Levobupivacaine 0.5% and bupivacaine 0.5% were shown to be equally effective in spinal anaesthesia. In previous studies, low dose bupivacaine with an intrathecal opioid was used successfully in urological surgery. The aim of this study was to evaluate the clinical effectiveness and block quality of low dose levobupivacaine, and compare it with low dose bupivacaine when they are combined with fentanyl in transurethral resection of prostate surgery.
Forty nine patients undergoing transurethral prostate surgery were enrolled in this prospective, randomized and double blind study. Patients in levobupivacaine group received 5 mg levobupivacaine + 25 μg fentanyl and bupivacaine group received 5 mg bupivacaine + 25 μg fentanyl. Demographic data, surgery times, hemodynamic parameters, block qualities and patient and surgeon satisfactions were recorded.
Demographic data, surgery times and patient and surgeon satisfactions were similar in both groups. Hemodynamic parameters were comparable and stable during the procedure in both groups. Sensory block characteristics were comparable and clinically effective in both groups. While 3 patients in bupivacaine group had Bromage score of 3 at the beginning of the surgery, no patient in levobupivacaine group had this score and this difference was significant (p = 0.042). Bromage scores at the end of the surgery were comparable in both groups.
In conclusion, for transurethral prostate surgery 5 mg levobupivacaine with 25 μg fentanyl can provide stable hemodynamic profile, patient and surgeon satisfaction and effective sensorial blockade with less motor blockade in spinal anaesthesia; so it could be used at low doses as a good alternative to bupivacaine.
The new antiepileptic medications are prescribed for the treatment of patients with seizure disorders since 17 years ago. Gabapentin (GBP) was approved on January 1994 as adjunctive treatment in patients 12 years or older with partial seizures, with or devoid of secondary generalization. GBP, was formerly known as an anticonvulsant γ-aminobutyric acid (GABA) mimetic, is considered as a safe and well-tolerated antiepileptic drug (AED) with promising pharmacokinetic properties and a wide therapeutic index. GBP is useful for the therapy of mixed seizure disorders and refractory partial seizures in children. GBP must be regarded as the first treatment for older patients with recently diagnosed seizures. GBP has a well recognized clinical efficacy in those types of focal epilepsy which were resistant to the traditional AEDs. The main object of this review was to evaluate the efficacy, tolerability, dosing schedules and safety of GBP that have been investigated in peer-reviewed journals.
Acne scarring is treatable by a variety of modalities. Ablative carbon dioxide laser (ACL), while effective, is associated with undesirable side effect profiles. Newer modalities using the principles of fractional photothermolysis (FP) produce modest results than traditional carbon dioxide (CO(2)) lasers but with fewer side effects. A novel ablative CO(2) laser device use a technique called ablative fractional resurfacing (AFR), combines CO(2) ablation with a FP system. This study was conducted to compare the efficacy of Q-switched 1064-nm Nd: YAG laser and that of fractional CO(2) laser in the treatment of patients with moderate to severe acne scarring.
Sixty four subjects with moderate to severe facial acne scars were divided randomly into two groups. Group A received Q-Switched 1064-nm Nd: YAG laser and group B received fractional CO(2) laser. Two groups underwent four session treatment with laser at one month intervals. Results were evaluated by patients based on subjective satisfaction and physicians' assessment and photo evaluation by two blinded dermatologists. Assessments were obtained at baseline and at three and six months after final treatment.
Post-treatment side effects were mild and transient in both groups. According to subjective satisfaction (p = 0.01) and physicians' assessment (p < 0.001), fractional CO(2) laser was significantly more effective than Q- Switched 1064- nm Nd: YAG laser.
Fractional CO2 laser has the most significant effect on the improvement of atrophic facial acne scars, compared with Q-Switched 1064-nm Nd: YAG laser.
Amyloid A (AA) amyloidosis is a multisystem, progressive and fatal disease. Renal involvement occurs early in the course of AA. We aimed to investigate the etiology, clinical and laboratory features, and outcome of patients with biopsy-proven renal AA amyloidosis.
Materials and Methods:
A total of 121 patients (male/female: 84/37, mean age 42.6 ± 14.4 years) were analyzed retrospectively between January of 2001 and May of 2013. Demographic, clinical and laboratory features and outcomes data were obtained from follow-up charts.
Familial Mediterranean fever (37.2%) and tuberculosis (24.8%) were the most frequent causes of amyloidosis. Mean serum creatinine and proteinuria at diagnosis were 2.3 ± 2.1 mg/dL and 6.7 ± 5.3 g/day, respectively. Sixty-eight (56.2%) patients were started dialysis treatment during the follow-up period. Mean duration of renal survival was 64.7 ± 6.3 months. Age, serum creatinine and albumin levels were found as predictors of end-stage renal disease. Fifty patients (%41.3) died during the follow-up period. The mean survival of patients was 88.7 ± 7.8 months (median: 63 ± 13.9). 1, 2 and 5 years survival rates of patients were 80.7%, 68.2% and 51.3%, respectively. Older age, male gender, lower levels of body mass index, estimated glomerular filtration rate, serum albumin, calcium, and higher levels of phosphor, intact parathyroid hormone and proteinuria were associated with a higher mortality. Higher serum creatinine, lower albumin, dialysis requirement and short time to dialysis were predictors of mortality.
The outcome of patients with AA amyloidosis and renal involvement is poor, particularly in those who had massive proteinuria, severe hypoalbuminemia and dialysis requirement at the outset.
Rheumatoid arthritis (RA) is a chronic, systemic, inflammatory disease with autoimmune etiology, characterized by synovial inflammation and destruction of joint cartilage and bone. There are controversial data about the profile of interleukin-17 (IL-17A), interleukin-4 (IL-4), and interferon-gamma (INFγ), indicating in some studies the key role of IL-17, while in others the Th1 cytokines.
Serum samples of 31 early RA patients were evaluated for erythrocytes sedimentation rate (ESR), rheumatoid factor (RF), C-reactive protein (CRP), anti-cyclic citrullinated peptide antibodies (anti-CCP), and for the tested cytokines (IL-17A, IL-4, and INFγ). Disease activity score (DAS28) calculation was done for all patients. Control serum samples were obtained from 29 healthy volunteers.
The levels of tested cytokines were significantly higher (IL-17A, p < 0.001; INFγ, p < 0.001; IL-4, p < 0.01) in patients with early RA, compared to the healthy controls. In early RA patients, a strong correlation of serum IL-17A was found with DAS28, ESR, and CRP. Also, significant negative correlation was found between serum INFγ levels and the DAS28 score, indicating that INFγ may play a key role in maintaining immune homeostasis in patients with RA.
The mean serum IL-17A levels in patients with early RA, corresponded with the disease activity and severity. This might highlight the usefulness of the serum IL-17A level in defining the activity and predictive patterns, for aggressive disease therapy, and it might express specific therapeutically targets.
Gastric carcinoma is the second most common cause of cancer-related death in Iran. It is well-known that atrophic gastritis is a major risk factor for gastric cancer, which leads to variations in the serum levels of gastrin 17 (G-17), pepsinogen I (P-I), and pepsinogen II (P-II). The aim of this study was to investigate the diagnostic accuracy of these serum biomarkers in the early detection of atrophic gastritis.
A total of 132 dyspeptic patients underwent upper endoscopy and biopsies were taken. The biopsy specimens were evaluated as the gold standard according to operative link for gastritis assessment staging system. Serum levels of G-17, P-I, and P-II were investigated using enzyme-linked immunosorbent assay. Receiver operating characteristic (ROC) analysis was used to calculate the diagnostic indices and optimal cut-off values using Statistical Package for the Social Sciences SPSS statistical software.
A total of 67 men and 65 women were analyzed, among which 48 (36.4%) had atrophic gastritis. The mean age was 45.8 (±15.8) years. ROC curve analysis demonstrated that the biomarkers (including pepsinogen I/II [P-I/II] ratio), except for P-I, are diagnostically significant in detecting gastric atrophy. The area under the curve (95% confidence interval [CI]) for G-17, P-I, P-II, and P-I/II ratio were 0.65 (0.55-0.76), 0.42 (0.32-0.53), 0.62 (0.52-0.72), and 0.61 (0.50-0.72), respectively. However, the diagnostic indices were low (sensitivity <50%, specificity < 90%). The prevalence of Helicobacter pylori infection was significantly higher in patients with atrophy against those without atrophy (75.0% vs. 57.4%, P value < 0.0001).
In the studied population, the serum biomarkers of atrophic gastritis are not useful screening tests due to their low sensitivity.
The aim of this study is to evaluate the outcome of an innovative, minimally invasive sling technique with autologous tissue in women with concomitant incontinence and anterior vaginal wall prolapse (AVWP).
Fifty-six women with stress urinary incontinence (SUI) or mixed urinary incontinence and AVWP were randomly assigned into two groups: In Group A (26 patients), anterior colporrhaphy (Kelly placation) and sling placement using a strip of anterior vaginal wall were performed, and in Group B (30 patients), transvaginal mesh correction of AVWP and tension-free vaginal tape (TVT) insertion (retropubic - craniocaudal route) using polypropylene mesh were carried out. The patients were followed-up for over 18 months and were assessed objectively using a 48 h frequency-volume chart, a 48 h pad test and a standardized stress test. Related surgical complications and outcomes were recorded and compared.
Surgical cure rates for Group A and Group B at the first (3 days) and last (18 months) post-operative visits were 62% and 84%; and 54%, and 72%, respectively (P = 0.09 and 0.31). Complications occurred in 9 patients (44%) of Group B, but only 3 patients (12%) in Group A.
Vaginal sling surgery using an anterior vaginal wall strip can improve SUI and in comparison with propylene mesh is associated with lower complication rates. Although, the surgical success rate of this technique is lower than T-Sling, larger studies with selected patients will help assess the suitable patients for this pelvic reconstructive surgery.
Carbamazepine has been used as AEDs since 1965, and is most effective against partial seizures. Two basic mechanisms of action have been proposed: 1) enhancement of sodium channel inactivation by reducing high-frequency repetitive firing of action potentials, 2) and action on synaptic transmission. The aim of this study was to provide a review of carbamazepine pharmacokinetics and its management guidelines in Iranian epileptic population.
Directory of Open Access Journals (DOAJ), Google Scholar, Pubmed (NLM), LISTA (EBSCO), Web of Science were searched; 1600, 722 and 167 research and review articles relevant to the topics; carbamazepine pharmacokinetics, carbamazepine pharmacokinetics in epilepsy and review on carbamazepine pharmacokinetics in epilepsy were found, respectively.
Carbamazepine is highly bound to plasma proteins. In patients the protein-bound fraction ranged from 75-80% of the total plasma concentration. Bioavailability ranges from 75-85%. The rate or extent of absorption was not be affected by food. It is completely metabolized and the main metabolite is carbamazepine-epoxide (CBZ-E). Carbamazepine induces its own metabolism, leading to increased clearance, shortened serum half-life, and progressive decrease in serum levels. Increases in daily dosage are necessary to maintain plasma concentration. Severe liver dysfunction may cause disordered pharmacokinetics. In cardiac failure, congestion of major vital organs, including kidneys, may result in abnormally slow absorption and metabolism.
Carbamazepine shows variability due to its narrow therapeutic window. Therefore clinical management in a3n Iranian epileptic population should focus on results derived from therapeutic drug monitoring in order to reduce inter and intra- individual variability in plasma drug concentrations.
By providing a picture from published articles in a field, bibliometric studies can inform policy-makers in their challenging research funding decisions. In this regard, we applied bibliometric analysis to the Iranian pediatrics articles published in PubMed indexed journals between 1975 and 2007.
We evaluated all pediatric articles that had been published from Iran in different PubMed indexed journals from 1975 to 2007. Journal data (i.e. date of publishing, journal name, impact factor of the journal, language), authors data (i.e. number of authors, international collaboration, affiliation of the corresponding author), and paper characteristics [i.e. type of article, research design, study population (neonate, infant, child, and adolescent), and specialty] were registered.
During this period of time, 819 articles from Iran had been published in PubMed indexed journals, with a sharp increasing trend after 2002. Impact factors were up to 25.8. Paper had an international co-author in 13.7%. Regarding study population, 24.1% of studies were published on neonates, 23.6% on infants, and the remaining 66.3% of studies were performed on children and adolescents from 2 to 18 years old. Infectious disease was the most frequent area of research, followed by public health and metabolic disease. Original articles were the most frequent type (89.7%) of the published articles. Study design was cross-sectional in 51.2%, retrospective in 36.3%, and prospective in 11.6%. Clinical trials made up 4.8% of the total papers.
Contribution of Iran in production of pediatrics science is showing a sharp increase after 2002, this pattern is in parallel with other research fields.
Iraq fought three wars in three consecutive decades, Iran-Iraq war (1980-1988), Persian Gulf War in 1991, and the Iraq's war in 2003. In the nineties of the last century and up to the present time, there have been anecdotal reports of increase in cancer in Ninawa as in all provinces of Iraq, possibly as a result of exposure to depleted uranium used by American troops in the last two wars. This paper deals with cancer incidence in Ninawa, the most importance province in Iraq, where many of her sons were soldiers in the Iraqi army, and they have participated in the wars.
The data was derived from the Directorate of Health in Ninawa. The data was divided into three sub periods: 1980-1990, 1991-2000, and 2001-2010. The analyses are performed using Poisson regressions. The response variable is the cancer incidence number. Cancer cases, age, sex, and years were considered as the explanatory variables. The logarithm of the population of Ninawa is used as an offset. The aim of this paper is to model the cancer incidence data and estimate the cancer incidence rate ratio (IRR) to illustrate the changes that have occurred of incidence cancer in Ninawa in these three periods.
There is evidence of a reduction in the cancer IRR in Ninawa in the third period as well as in the second period. Our analyses found that breast cancer remained the first common cancer; while the lung, trachea, and bronchus the second in spite of decreasing as dramatically. Modest increases in incidence of prostate, penis, and other male genitals for the duration of the study period and stability in incidence of colon in the second and third periods. Modest increases in incidence of placenta and metastatic tumors, while the highest increase was in leukemia in the third period relates to the second period but not to the first period. The cancer IRR in men was decreased from more than 33% than those of females in the first period, more than 39% in the second period, and regressed to 9.56% in the third period.
Our paper confirms the media reports that there are increases in the number of cancer cases, but when it analyzed statistically with population growth in the Ninawa province, there are decreases in incidence rates in most cancer types.
This study aimed to compare the cytochrome P450 1A1 (CYP1A1) gene expression in the cord blood of infants born from mothers living in low- and high-air polluted areas.
The study was conducted in Spring 2012 in Isfahan, the second large and air-polluted city in Iran. The study comprised 60 neonates, consisting of 30 infants born from mothers residing in areas with high levels of air pollution and an equal number of infants born in areas with a lower air pollution level. The umbilical cord blood sample was taken immediately after birth. The relative gene expression levels of CYP1A1 were examined using real time-polymerase chain reaction method.
CYP1A1 gene expression level was 3.3-fold higher in the group living in areas with higher pollution level than in the other group (P = 0.01). No significant difference existed in the mean values of maternal age, gestational age, the newborns' birth weight, and the gender distribution between the two groups.
This study provides confirmatory evidence of prenatal health hazards of ambient air pollution and highlights the need for pollution prevention programs to protect women of childbearing age and their children. The clinical implications of this study finding should be confirmed in future longitudinal studies.
Endometriosis is a chronic and progressive gynecological disorder and is manifest by dysmenorrhea and a major cause of infertility and chronic pelvic pain. The study was designed to compare the value of cervico-vaginal fluid of interleukin-1α (IL-1α) in patients with and without endometriosis.
Fifty women were assessed in this case control study. The case group included 25 patients with endometriosis. The control group included 25 women without any evidence of endometriosis or any other genital disease. Endometriosis was confirmed by laparoscopy and histopathological examination. Cervico-vaginal fluid samples were obtained from patients during the follicular phase and preup surgery to assess the levels of IL-1α in cervico-vaginal fluid. The level of IL-1α was assessed using commercially available Avi Bionhuman Enzyme-Linked Immunosorbent Assay kits (FIN-01720, Vantaa, Finland) for IL-1α. Receiver-operator curve analysis was used to estimate the power of IL-1α to distinguish subjects with endometriosis from controls.
The cervico-vaginal fluid level of IL-1α in cases was 210.44 ± 40.11 pg/mL and in controls was 54.28 ± 25.73 pg/mL, the differences between two groups was statistically significant (P < 0.0001). The cut-off point for cervico-vaginal fluid IL-1 for endometriosis was 105 pg/mL, with a sensitivity of 100% (95% confidence interval [CI]: 86.2-100), and specificity of 100% (95% CI: 86.2-100).
Results show a significant increase in the cervico-vaginal fluid levels of IL-1α, in women with endometriosis, that it can be a useful marker in the diagnosis of endometriosis.
Methotrexate, a toxic antimetabolite that limits cellular reproduction by acting as an antagonist to folic acid, has been used to control autoimmune disease with different results. The aim of this study was to evaluate the effectiveness of low dose Methotrexate in the relapsing-remitting multiple sclerosis (RRMS).
Eighty patients with definite RRMS aged 15 to 55 years were randomly allocated to receive a 12-month treatment course of either oral Methotrexate (7.5 mg/week) or intramuscular Interferon β-1α (30 μg/week). Response to treatment was assessed at 12 months after start of therapy.
The results of the study demonstrated significant reduction in relapse rate in both groups (p < 0.01). In 40 patients treated by Methotrexate, the mean value (SD) of relapse rate decreased from 1.75 (0.74) to 0.97 (0.83) (p < 0.01). Correspondingly, the mean value (SD) of relapse rate in patients treated by Interferon β-1α decreased from 1.52 (0.59) to 0.57 (0.78) (p < 0.01). Decrease of relapse rate in Interferon β-1α group was more than that in the other group (p = 0.06).
This study suggests that although treatment with Methotrexate may significantly reduce relapse rate and slow progression of disease in patients with RRMS, its efficacy is less than Interferon β-1α and it may be better used as add-on therapy.
The efficacy of Mycophenolate mofetil (MMF) plus interferon beta-1a (IFNB-1a) in treatment of relapsing-remitting multiple sclerosis (RRMS) was evaluated.
This was a pilot study with randomized, double-blinded, placebo-controlled design. Patients with RRMS and Expanded Disability Status Scale score (EDSS) of < 6.0 were included. Those with relapse within the previous two months and prior use of immunomodulatory/immunosuppressive drugs were excluded. Patients were randomized into MMF (n = 13) and placebo (n = 13) groups and received weekly intramuscular IFNB-1a plus either MMF or placebo. MMF started by 500 mg/d for one week and weekly escalated by 500 mg/d, until target divided dose of 2000 mg/d and continued for 12 months. Radiologic and clinical assessments were performed at baseline and then at month 12.
After one year of therapy, difference between the two groups in number of new T2 lesions was not statistically significant (0.54 ± 0.77 in MMF vs. 1.85 ± 3.2 in placebo group, p = 0.169). Two patients in the placebo group had gadoliniumenhanced lesions and one patient had relapse. There were 3 patients in each group with more than one point progression in EDSS. Common side effect in the MMF group included gastrointestinal upset, but no patient discontinued the treatment.
Combination of MMF with IFNB-1a in patients with RRMS is well tolerated, but the efficacy of such combination was not statistically significant in this pilot study and deserves further investigation with a larger sample size and a longer follow-up.
National Institute of Environmental Health Sciences (NIEHS) scientists shows that long-term exposure to air pollutants increases the risk of respiratory diseases such as allergies, asthma, chronic obstructive pulmonary disease, and lung cancer. Children and the elderly are particularly vulnerable to the health effects of ozone, fine particles, and other airborne toxicants. Air pollution factors are considered as one of the underlying causes of respiratory diseases. This study aimed to determine the association of respiratory diseases documented in medical records and air pollution (Map distribution) of accumulation in Isfahan province, Iran. By plotting the prevalence and spatial distribution maps, important differences from different points can be observed.
The geographic information system (GIS), pollutant standards index (PSI) measurements, and remote Sensing (RS) technology were used after entering data in the mapping information table; spatial distribution was mapped and distribution of Geographical Epidemiology of Respiratory Diseases in Isfahan province (Iran) was determined in this case study from 2005 to 2009.
Space with tracing the distribution of respiratory diseases was scattered based on the distribution of air pollution in the points is an important part of this type of diseases in Isfahan province where air pollution was more abundant.
The findings of this study emphasis on the importance of preventing the exposure to air pollution, and to control air pollution product industries, to improve work environmental health, and to increase the health professionals and public knowledge in this regard.
Cancer incidence rate is increasing in the world particularly in developing countries. The awareness regarding cancer incidence and distribution helps policy makers and researchers to design comprehensive plan for controlling cancer. The aim of this study was to determine the incidence rate and trend of cancer in Isfahan area, one of the most importance provinces of Iran.
Data of Isfahan cancer registry were derived from 2005 to 2010. Direct standardization through world standard population produced by the world health organization was used and adjusted standard rate (ASR) was calculated. The Poisson regression analysis was employed to estimate cancer incidence trend during 5 years.
The new cases of cancer were 24771 patients from 2005 to 2010. Mean age of these patients was 56.1 ± 18.0 years and 54.6% were male. Male patients were approximately 7 years older than females. The most frequent cancer was gastrointestinal in men and breast cancer in women. The rate of cancer increased approximately 4 per 1000 population and incidence rate ratio (IRR) was 1.004 (95%CI: 1.002-1.005).
The rate of cancer is increasing rapidly in Isfahan province. Cancer control and comprehensive prevention plan for Isfahan is necessary.
This study aimed to determine the secular trends in the national prevalence of overweight and obesity among 6-year-old Iranian children, and to compare the results in Northern, Central and Southern parts of the country.
The data were collected as part of a routine and mandatory national screening program on children entering elementary schools in 2007, 2008 and 2009.
The study population comprised 2,600,065 children including 862,433 in 2007, 782,244 in 2008 and 955,388 in 2009. Of total children 12.8%, 13.5% and 10.9% were overweight in 2007, 2008 and 2009, respectively (P > 0.05). The corresponding figures for obesity were 3.4%, 3.5% and 3.4%, respectively (P > 0.05). In all surveys, the prevalence of overweight was higher in Southern region than in the other two regions. P for trend was not significant for prevalence rates of overweight and obesity in any of the regions.
To the best of our knowledge, this study was the first of its kind in presenting the nationwide trend of overweight and obesity in young children living in a developing country. It showed a considerably high prevalence of overweight and obesity, but with a constant rate in three years. The higher prevalence of overweight in Southern region than in Central and Northern regions might be related to the lower socioeconomic position of this population. At a very young age, children's lifestyle is more under control of parents. Primordial and primary prevention efforts against the overweight epidemic can be effective and shall be further strengthened.
Pandemic 2009 H1N1 influenza A virus arrived at Isfahan in August 2009. The virus is still circulating in the world. The abnormal thoracic computerized tomographic (CT) scan findings vary widely among the studies of 2009 H1N1 influenza. We evaluated the thoracic CT findings in patients with 2009 H1N1 virus infection to describe findings compared to previously reported findings, and to suggest patterns that may be suggestive for 2009 influenza A (H1N1) in an appropriate clinical setting.
Retrospectively, the archive of all patients with a diagnosis of 2009 H1N1 influenza A were reviewed, in Al-Zahra Hospital in Isfahan, central Iran, between September 23(rd) 2009 to February 20(th) 2010. Out of 216 patients with confirmed 2009 influenza A (H1N1) virus, 26 cases with abnormal CT were enrolled in the study. Radiologic findings were characterized by the type and pattern of opacities and zonal distribution.
Patchy infiltration (34.6%), lobar consolidation (30.8%), and interstitial infiltration (26.9%) with airbronchogram (38.5%) were the predominant findings in our patients. Bilateral distribution was seen in 80.8% of the patients. Only one patient (3.8%) showed ground-glass opacity, predominant radiographic finding in the previous reports and severe acute respiratory syndrome (SARS).
The most common thoracic CT findings in pandemic H1N1 were patchy infiltration, lobar consolidation, and interstitial infiltration with airbronchogram and bilateral distribution. While these findings can be associated with other infections; they may be suggestive to 2009 influenza A (H1N1) in the appropriate clinical setting. Various radiographic patterns can be seen in thoracic CT scans of the influenza patients. Imaging findings are nonspecific.
During August 2009, novel H1N1 influenza virus began causing illness in Isfahan. Since rates of hospitalization and mortality due to the disease have varied widely in different countries, we described the clinical, radiologic, and demographic features of H1N1 hospitalized patients in a hospital in Isfahan.
This cross-sectional study was conducted in Alzahra Hospital during September 2009 to February 2010. Totally, 216 patients with confirmed, probable, or suspected cases of 2009 influenza A (H1N1) were admitted.
Most patients were women (50.5%). Mean age of patients was 26.6 ± 19.5 years. The most common complains on admission were respiratory symptoms (91.6%, n= 198), fever (88.4%, n = 191), myalgia (65.7%, n = 142). In addition, 120 patients (56%) had at least one underlying medical disorder. Thirty-six patients (16.7%) died. Mortality was higher in children under 5 years old (10/36, 10%) and female cases (63.9% of died patients). Predicting variables affecting mortality were intensive care unit (ICU) admission and procalcitonin (PCT) > 0.5. Antiviral treatment was prescribed for 200 (92.5%) of the 216 patients.
Based on the findings of the present study, novel H1N1 influenza is highly prevalent among the youth. Moreover, it causes a relatively high morbidity rate. Therefore, people need to be encouraged to have vaccination against 2009 H1N1. Early diagnosis and treatment is related to less admission and shorter duration of hospitalization.
Health equity audit, as an alternative solution, is a process by which local partners systematically review inequalities in the patients` health, their access to appropriate services and health system outputs. Then, necessary activities needed in order to have more equitable services are agreed on and these concurrences become the executive scheme and action initiates. Therefore, it is pivotal for health care organizations to pay special attention to this important topic. The objective of the current study was to review the health equity audit model in different countries to gather viewpoints of various involved groups in health sector, particularly health experts, and to offer a practical and appropriate model for health equity audit in Iran.
This study adopted applied research approach in two phases. In the first step, this study conducted theoretical health equity audit models in the texts; the experiences of other countries were studied and the most appropriate model for Iranian health system was selected. In the second step, this study employed the Delphi technique. According to the Delphi technique the questionnaire applied in order to gather data and then, the final model was extracted.
Agreeable topics, performing agencies, 6 equity audit stages, and equity indicators under 3 main parts with 16 sub-sections were elaborated and viewpoints of Iranian experts in the above fields were gathered and presented as the proposed health equity audit model for Iran.
This study reviewed the model of health equity audit for UK and provided a comparative model for health system of Iran with respect to the opinions of academic experts.
Attention deficit hyperactivity disorder (ADHD) is the most common childhood behavioral disorder causing hyperactivity, attention deficit and education decline among students. The teachers may not have enough knowledge about this disorder and are in a real need in this field. Teachers' education is one of the ways to get knowledge about this disorder. Nowadays, finding a way like a short term nonattendance education method is highly in demand. Therefore, the aim of the study was to compare effectiveness of nonattendance and workshop education of primary school teachers on their knowledge, attitude, and function towards ADHD students.
Sixty seven primary school teachers from the First Districts of Education Department of Isfahan were randomly selected and put into two groups of workshop education (33 participants) and nonattendance education (34 participants). At first, both groups filled demographic date questionnaires and then, were given a pretest. Post tests were given after a two day education in workshop group and after ten days in nonattendance group who had studied the related booklet. Finally, the mean post test scores of knowledge, attitude and knowledge of function were compared between the two groups using ANCOVA analysis.
After intervention, the mean scores of knowledge between the two groups was not significantly different whereas the mean scores of attitude and the mean scores of knowledge of function showed a significant difference between the two groups.
Nonattendance education was as effective as workshop education in promotion of teachers' knowledge, but workshop education was more effective in attitude change and promotion of teachers' knowledge of function about dealing with ADHD students.
Low urine pH is related to obesity and insulin resistance, which are components of metabolic syndrome (MS). The aim of this study was to identify the relation between a low urine pH and MS after controlled for other covariates including demographic and lifestyle factors in adult Korean population.
Materials and Methods:
We analyzed data from the 2010 Korea National Health and Nutrition Examination Survey, a cross-sectional and nationally representative survey and 1960 men and 2702 women were included in this study. Study subjects were divided into the group with urine pH <5.5 and the group with urine pH ≥5.5 refer to literature. We then evaluated the association between low urine pH and MS.
After adjusting for age, sex, smoking status, drinking status, regular exercise, and blood urea nitrogen level, the odds ratio (OR) for the presence of MS in the group with urine pH <5.5 was 1.350 (95% confidence interval [95% CI]: 1.158-1.573) using the American Heart Association/National Heart, Lung, and Blood Institute criteria or 1.304 (95% CI: 1.082-1.572) using the International Diabetes Federation criteria. Among MS components, elevated fasting glucose (OR: 1.231, 95% CI: 1.058-1.433, P = 0.007) and elevated triglyceride (TG) (OR: 1.389, 95% CI: 1.189-1.623, P < 0.001) showed a significantly high OR.
The findings confirmed that low urine pH is associated with MS in the Korean population. Among MS components, elevated fasting glucose and elevated TG showed a significantly high OR.
Pharmacovigilance assesses the safety profile of drugs. Its main aim is the increase of spontaneous reporting of adverse drug reactions (ADRs). The Italian Drug Agency (AIFA; Agenzia Italiana del Farmaco) is financing several projects to the aim of increasing reporting, and in Calabria a Pharmacovigilance Information Centre has been created.
We analyzed the AIFA database relatively to Calabria in the year 2011 and we have analyzed ADRs using descriptive statistics. We have also collected a questionnaire-based interview in order to describe the background knowledge in the field.
Regarding the number of AIFA reported ADRs from Calabria, a 38% increase (138 vs. 100) in comparison to 2010 was evidenced. Hospital Doctors represent the main source of signaling (71.7 %). Ketoprofene and the combination amoxicillin/clavulanic acid represent the most frequently reported drugs causing ADRs. Our questionnaires indicated that despite the health professionals have met at least once an ADR only a small percentage of them was reported to the authorities (37%). There is a very good knowledge of the ADR concept and reporting system (90% of interviewed distinguish an ADR and knows how to report it), and there is a strong interest in participating to training courses in the field (95% are interested).
Despite Calabria has had a positive increase in the number of reported ADRs, the total number is very low and the pharmacovigilance culture is far from being achieved in this region.
The anti-oxidant and immunomodulating natural agents may enhance the efficacy of cancer chemotherapy. One of the most important agents is the pineal hormone melatonin (MLT) which may exert both anti-oxidant and antiproliferative immunostimulating anticancer effects. This study was performed to evaluate the efficacy of a biochemotherapeutic regimen in metastatic cancer patients, and its therapeutic activity in relation to the psychospiritual status of patients.
The study included 50 metastatic non-small cell lung cancer (NSCLC) patients and a control group of 100 patients. Chemotherapy consisted of cisplatin plus gemcitabine. MLT was given orally at 20 mg/day in the evening. Patients were subdivided into 5 psychic profiles, as follows: spiritual faith, rationale faith, anxiety, apathy, and accusation behavior.
Tumor response rate was significantly higher in patients treated by chemotherapy plus MLT than in those treated by chemotherapy alone (21/50 vs. 24/100, p < 0.001). However, the percentage of objective tumor regressions obtained in patients with spiritual faith was significantly higher than that found in the overall other patients concomitantly treated by chemotherapy plus MLT (6/8 vs. 15/42, p < 0.01).
In conclusion, the efficacy of chemotherapy may be enhanced by the pineal hormone MLT, by representing a new promising biochemotherapeutic combination; also despite its objective ability to enhance chemotherapy efficacy, the activity of MLT is depending at least in part on the psychospiritual status of cancer patients, and it is maximal in the presence of a real spiritual faith.
Velo-cardio-facial syndrome (VCFS) is caused by a submicroscopic deletion on the long arm of chromosome 22 and affects approximately 1 in 4000 persons, making it the second most prevalent genetic syndrome after Down syndrome and the most common genetic syndrome associated with cleft palate. Most of the 22q11.2 deletion cases are new occurrences or sporadic; however, in about 10 % of families, the deletion is inherited and other family members are affected or at risk for passing this deletion to their children. This report describes a 1.5 years-old male child with clinical signs of velo-cardio-facial syndrome (VCFS) presented with heart defect, soft cleft palate, developmental delay, acrocephaly, seizure, MRI abnormalities and descriptive facial feature, such as hypertelorism. Array-CGH test was done to confirm the diagnosis; the result revealed a 2.6 Mbp deletion in 22q11.2 chromosome that containing TBX1 and COMT genes. Our data suggest that haploinsufficiency of TBX1 gene is probably a major contributor to some of the syndrome characteristic signs, such as heart defect. Because of developmental delay and dysmorphic facial feature were observed in the index's mother and relatives, inherited autosomal dominant form of VCF is probable, and MLPA (multiplex ligation-dependent probe amplification) test should be performed for parents to estimate the recurrent risk in next pregnancy.
Primary breast lymphoma (PBL) of the breast is a rare type of localized non-Hodgkin lymphoma, which is usually of the B-cell. The majority of breast lymphoma present as a unilateral painless breast masses in an older woman, average age at diagnosis 55-60. A less common but distinctive presentation is a young woman of childbearing age who presents during or immediately after pregnancy. We present a 23-year-old postpartum woman with bilateral breast swelling. After surgical drainage and debridement and pathologic examination, the diagnosis of breast Burkitt lymphoma (BL) was confirmed. Chemotherapy was immediately started for her and the patient showed a good response with complete remission.
Sulfur mustard (SM) is an incapacitating chemical warfare agent, which has been widely employed in particular regions including Iran. We investigated and reported delayed biochemical and hematological complications of SM in severely toxic Iranian veterans 23 years after exposure.
Forty-two Iranian veterans, residents of Khorasan Razavi, poisoned by SM, and suffering from clinical complications were investigated. A total of 30 healthy male volunteers were also selected as a control group. Biochemical and hematological variables were measured for the case and control groups. Data were analyzed using a Student's t-test by InStat software (GraphPad Inc., San Diego, CA) to determine significant differences between the data from the two groups.
The percentages of reticulocytes were significantly higher in patients (0.82 ± 0.04, P < 0.05). Total protein and albumin levels were significantly lower in veterans (total protein: 7.58 ± 0.07 g/dL, albumin: 4.97 ± 0.04 g/dL, P < 0.01). In addition, we observed a significant increase in serum cholesterol (226.74 ± 5.23 mg/dL, P < 0.01), triglyceride (173.53 ± 17.05 mg/dL, P < 0.05), and gamma-glutamyl transferase (GTT) activity of the patients (44.04 ± 3.35 IU/L, P < 0.05).
Results showed that SM can cause long-term effects on some biochemical factors of veterans. As many of the functional tests of liver and kidney between two groups were statistically unchanged, it seems that the observed biochemical changes may be secondary to delayed respiratory complications of the patients.
Diabetic nephropathy is the major cause for chronic renal failure (CRF) and proteinuria is an independent risk factor for end stage renal disease. Hence, early identification and quantification of proteinuria is of prime importance in the diagnosis and management.
This study was conducted amongst 42 diabetic subjects from HSK hospital, Bagalkot. Twenty four-hour urine protein and random urine protein to creatinine ratio (P:C) was determined. Pearson's correlation, sensitivity, specificity, positive and negative predictive values were determined using 24-hour urinary protein as a gold standard for spot urine P:C ratio. ROC curve and area under curve was also determined using SPSS (11.5) software. All the results were expressed in mean±SD.
Forty two diabetes mellitus patients participated in this study. The average of 24 hour urinary protein was 1.6 ± 1.7 gm/day. The spot urine P:C ratio was 1.27 ± 1.55. There was a positive correlation between 24 hours urinary protein and spot urine P:C ratio (r = 0.925, p < 0.0001). The area under the ROC curve for urine P:C ratio at various cutoff was 0.947 (95% confidence interval: 0.831-0.992, p < 0.0001). The sensitivity and specificity was 80.65% and 100% respectively at P:C ratio cutoff of 0.3.
The random urine P:C ratio predicts the amount of 24-hour urinary protein excretion with high accuracy. Hence it can be used as a faster diagnostic substitute for 24-hour urinary protein estimation.
Definitions of chronic kidney disease (CKD) in many catheterization laboratories have relied on the serum creatinine (Scr) rather than glomerular filtration rate (GFR). Regarding that CKD is the primary predisposing factor for contrast induced nephropathy (CIN), we compared the sensitivity of calculated GFR by 24-h Urine creatinine with Cockcroft-Gault (CG) equation and Scr level to define at risk patients for CIN who were undergone coronary angiography (CAG).
Two hundred fifty four subjects who were candidate for CAG and had normal creatinine level were enrolled. Before CAG, GFR was calculated from a 24-h urine collection, CG equation and a single Scr sample regarding to previously described protocol. Contrast volume used for each case <100 ml. CIN was defined as a 0.5 mg/dL or 25% elevation in the Scr.
CIN occurred in 10.6%. Baseline GFR, the volume of contrast agent, and diabetes were the independent risk factors for CIN. GFR was less than 60 ml/min/1.73 m2 in 28% and 23.2% of patients regarding to 24-h urine creatinine and CG equation, respectively. In CIN prediction, 24-h urine creatinine estimated GFR had 85.2%, 59.3% and CG equation GFR had 78.9%, 81.1% sensitivity and specificity, respectively.
Although, GFR estimated by CG equation has less sensitivity than GFR calculated from 24-h creatinine in CIN probability, but it is better than Scr alone and because of cost-effectiveness and convenience using of this method, we suggest at least using CG equation for GFR calculation before CIN, especially in diabetic and/or older than 60 years cases.
Metabolic syndrome (MetS) is a serious public health problem. It is an important risk factor of cardiovascular disease in developed countries. Adipose tissue considered as an organ that releases a variety of molecules referred to adipocytokines such as leptin. Polymorphism of their related genes may play an important role in development of MetS. The aim of this study was to determine the association of leptin gene-2548G/A (LEP-2548G/A) polymorphism with lipid profile in subjects with and without Mets.
In this case/control study a frequency of LEP-2548G/A single nucleotide polymorphism was determined between 200 patients (142 women and 58 men) and 200 controls (122 women and 78 men). Both groups were selected randomly from Hamadan city, Iran. Blood samples were collected then followed by routine biochemical analysis, DNA extraction and serum leptin measurements. Polymerase chain reaction-restriction fragment length polymorphism was applied to identify LEP-2548G/A genotypes. Statistical analyses were applied using SPSS software version 10. Continuous variables were presented as means± SD and compared by independent sample t-test. Variables without normal distribution compared through Mann-Whitney U test.
In both groups, a significant difference was observed between biochemical factors and leptin concentration. Serum leptin concentration was more in females than males. No statistical significant difference was detected in the frequency of LEP-2548G/A polymorphism between both MetS and healthy groups.
In summary, it is concluded that frequency of LEP G-2548A polymorphism in Metabolic syndrome (MetS) and healthy subjects was not significantly different and more research with large sample size is needed in this area.
Primary bone lymphoma (PBL) is a rare disease and distinct clinicopathological entity. The optimal treatment strategy is still unclear. Because of rarity of PBL, we report our institute experience in PBL clinicopathological feature and treatment results.
28 patients diagnosed with PBL were referred to Omid Hospital, cancer research center (CRC), between March 2001 and February 2009. Immunophenotype studies on 16 out of 28 pathological blocks were performed. We analyzed disease free survival (DFS) and overall survival (OS) rates.
14 patients with PBL were analyzed retrospectively. 17 patients (60.7%) were male and 11 (39.3%) were female with a median age of 41 years (range: 11-79). Long bones were the most primarily site of involvement (71%). 26 (93%) patients had diffuse large B cell lymphoma and 2 (7%) had small lymphoblastic lymphoma. One (3%) patient received radiation alone, 18 (66%) cases received combined modality (chemotherapy + radiotherapy) and 8 (30%) received only chemotherapy during their treatment period. The median follow up was 18 months (range: 1-82). Mean DFS was 51 months (range: 37-66). Overall survival (OS) was 54 months (range: 40-68). OS was significantly better in the chemoradiotherapy group compared with other two groups (64 versus 27 months, respectively, p=0.014). DFS was also significantly better in combined modality arm compared with other two groups (64 versus 21 months, respectively, p=0.003).
In spite of small number of patients reported in this study, combined modality treatment (chemotherapy and radiotherapy) was shown to be useful as an effective treatment strategy in PBL.
The aim of this study was to evaluate the effectiveness of monotherapy with interferon alpha-2b and combination therapy with interferon alpha-2b plus ribavirin on chronic hepatitis C infection in thalassaemic patients.
In parallel group randomized, double blind, controlled trial, 32 thalassaemic patients with chronic hepatitis C infection completed the study. In a random fashion, one group was treated with three million units of interferon alpha-2b three times a week plus ribavirin (800-1200 mg daily). The second group received interferon alpha-2b alone. Treatment duration was 24-48 weeks. Primary efficacy variables were HCV RNA after treatment and sustained viral response (SVR) six months after treatment.
The mean age of patients was 22 ± 7.4 years; 19 (59.4%) were male and 13 (40.6) were female. At the end of treatment, no statistically significant differences were found between the groups in HCV RNA and AST. The proportion of patients with SVR six months after treatment was significantly greater in the monotherapy group (90.9%) than in the combination therapy group (44.4%; p = 0.049). A significant difference in mean of ALT was also obtained at the end of treatment between monotherapy and combination therapy groups (30.4 ± 19.2 and 60.1 ± 48.9, respectively; p = 0.02). Response rates were not associated with genotype and severity of hepatitis C infection in both groups.
These results suggest that monotherapy may be considered as the first-line therapy in patients with thalassemia.
Recent findings suggest that production of pro-inflammatory cytokines, such as Tumour Necrosis Factor-alpha (TNF-α), is increased in the brain tissue of patients suffering late-onset Alzheimer's disease (LOAD) and play an important role in the pathogenesis of this disease. Several epidemiological studies also suggest that patients taking anti-inflammatory drugs have a decreased risk of developing AD. TNF-α is an important pro inflammatory cytokine that is unregulated in Alzheimer's patients. Functional polymorphisms in tumor necrosis factor alpha (TNF-α) can affect immune response, inflammation, tissue injury and possibly the susceptibility to Alzheimer disease (AD).
We used the polymorphic DNA markers (-308G/A) and (-863C/A) to study the association of TNF-α gene mutations with Late-onset Alzheimer's disease (LOAD) and the relation between clinical features and genotypes in affected individuals. A total of 160 patient samples and 163 healthy controls from west northern Iran (Eastern Azerbaijan) were genotyped for the two polymorphisms by the PCR-RFLP method and genotype frequencies were statistically determined.
Our data showed significant difference in TNF-α-308 G/A genotype and pro inflammatory cytokine allele frequencies between the Alzheimer disease patients and healthy subjects. Contrary to that, no significant difference was observed in TNF-α-863 C/A genotype and allele frequencies between these two groups.
TNF-α-308 G/A gene polymorphism could affect cerebral inflammatory response and the risk of late-onset Alzheimer disease but -863 C/A polymorphism does not influence the risk of this disease and this possible association between TNF-α -308G/A and -863C/A gene polymorphisms have to be further elucidated in larger case control studies.
Quality of life (QOL) improvement is the main objective of treating patients with irritable bowel syndrome (IBS). This study aimed to assess the validity, reliability, and factor analysis of IBS-QOL-34 questionnaire as a common transcultural instrument for Iranian IBS patients.
Two hundred and forty patients with IBS (based on gastroenterologists' diagnosis according to ROM III criteria) were referred to Digestive Health Clinic in Psychosomatic Research Center have been selected in this study. Aside with IBS-QOL-34, MOS 36-item short-form health survey (SF-36) and IBS severity index (IBSSI) questionnaires were completed by the cases for determination of correlation coefficients; the data were analyzed using descriptive statistics, factor analysis, Cronbach's alpha, Pearson correlation coefficient by Statistical Package for Social Sciences (SPSS) software, version 18.
Total reliability of the questionnaire was reported by using Cronbach's alpha as 0.95, ranging from 0.65 to 0.90. Correlation coefficients of concurrent implementation of IBS-QOL with SF-36 and IBSSI resulted in -0.61 and 0.64, respectively. Exploratory factor analysis using varimax rotation identified eight principle components, which will determine QOL at 67% variance.
According to the results, IBS-QOL-34 questionnaire has good psychometric properties in the research community and can be safely used as a valid tool to assess QOL of patients with IBS for healthcare and therapeutic purposes.
The symptoms of irritable bowel syndrome (IBS) are common in the general population. The aim of this population-based study was to determine the prevalence of IBS and describe the associated factors including demographic, life style and health-seeking behaviors in Shiraz city, southern Iran.
From April to September 2004, 1978 subjects aged > 35 years old completed a validated and reliable questionnaire on IBS.
The prevalence rate of IBS was 10.9%, higher in females, in 35-44 years old age group and among subjects eating fast food (14.1%) but was lower in those taking more fruits and vegetables (10.5%). The occurrence of anxiety, nightmare and restlessness was also significantly higher in subjects with IBS. It had an association with psychological distress and recurrent headaches but not with drinking tea/coffee, smoking or physical activity.
In our area, IBS was correlated with gender, age, psychological distress, recurrent headaches and consumption of fast foods that necessitate health planning programs by health policy makers.
This study was carried out to evaluate activities in different branches of science in Iran compared to other countries over the past 35 years.
Essential Science Indicators (ESI) and Web of Science from (Thomson Reuters ISI) and SCImago Journal & Country Rank (SJR) were searched for scientometrics data. ESI indicated place of Iran among other countries in all 22 scientific categories based on the publication and citation rates. SJR parameters, such as publication rate, citable publications, citation rate, citations per publication and the H-index were used to record the rank of Iran among the world's countries.
A progressive quantitative and qualitative growth of Iranian publications was evident. The field of chemistry in Iran was the most prolific in terms of the number of publications (16982) whereas economics and business was the least prolific (156). A growth in the quality of works of Iranian authors was evident by gaining higher H-index in the recent years.
If this scientific growth of Iran continues, it would not be surprising to see Iran as one of the most powerful countries in the field of science in the World.
Health related quality of life is an important outcome measure in studies involving patients with chronic neurological conditions. Disease specific patient reported outcome measures (PROMs) are increasingly used as primary end points in clinical trials. The most widely used disease specific PROM is the 39 item Parkinson's Disease Questionnaire (PDQ-39). The aim of this study was to determine validity and reliability of Persian PDQ-39.
Two hundred Parkinson's disease patients attending neurologic clinics of teaching hospitals were recruited. PD patients completed a translated version of the PDQ-39. Internal consistency reliability of the questionnaire was assessed by Cronbach's alpha coefficient. Reproducibility was assessed across the 3-week interval using the intraclass correlation coefficient. To assess convergent validity, results on the PDQ-39 were correlated with those gained on the SF-36. Discriminate validity of questionnaire was assessed by comparing PDQ-39 scores and the severity and the duration of disease.
A value of 0.93 (Cronbach's α) was gained for the summary score (PDQ-SI), indicating high levels of internal reliability. Alpha value of seven domains was greater than 0.70. The intraclass correlation coefficient ranged from 0.47 to 0.90. The range of correlation coefficients between domains of SF-36 and PDQ-SI was from -0.40 to -0.61. There was a statistically significant difference between severity of disease and mean scores of PDSI.
This study provides evidence that the Persian version of PDQ-39 is a valid and reliable measure of quality of life in PD.
Epigenetic event is a biological regulation that influences the expression of various genes involved in cancer. DNA methylation is established by DNA methyltransferases, particularly DNAmethyltransferase 3B (DNMT3B). It seems to play an oncogenic role in the creation of abnormal methylation during tumorigenesis. The polymorphisms of the DNMT3B gene may influence DNMT3B activity in DNA methylation and increase the susceptibility to several cancers. These genetic polymorphisms have been studied in several cancers in different populations.
In this study, we performed a case-control study with 125 colorectal cancer patients and 135 cancer-free controls to evaluate the association between DNMT3B G39179T polymorphism (rs1569686) in the promoter region and the risk of sporadic colorectal cancer. Up to now, few studies have investigated the role of this gene variant in sporadic colorectal cancer with no familial history. The genotypes of DNMT3B G39179T polymorphism was analyzed by PCR-RFLP.
We found that compared with G allele carriers, statistically the DNMT3B TT genotype (%34) was significantly associated with increased risk of colorectal cancer (adjusted OR, 3.993, 95% CI, 1.726-9.238, P = 0.001). Compared with DNMT3B TT genotype, the GT and GG genotypes had lower risk of developing sporadic colorectal cancer (OR = 0.848, 95% CI = 0.436-1.650).
Our findings were consistent with that of previously reported case-control studies with colorectal cancer. These results suggest that the DNMT3B G39179T polymorphism influences DNMT3B expression, thus contributing to the genetic susceptibility to colorectal cancer. Further mechanistic studies are needed to unravel the causal molecular mechanisms.
The performance of the subjects with above-knee amputation is noticeably poorer than normal subjects. Various types of components have been designed to compensate their performance. Among various prosthetic components, the knee joint has great influence on the function. Two types of knee joints (3R15, 3R20) have been used broadly for above-knee prostheses. However, there is not enough research to highlight the influence of these joints on the gait performance of the subjects. Therefore, an aim of this research was to investigate the performance of the above-knee amputees while walking with 3R15 and 3R20 knee joints.
7 above-knee amputees were recruited in this research study. They were asked to walk with a comfortable speed to investigate the gait function of the subjects with 3 cameras 3D motion analysis system (Kinematrix system). The difference between the performances of the subjects with these joints was compared by use of paired t-test.
The results of this study showed that, the performances of the subjects with 3R20 were better than that with 3R15. The walking speed of the subjects with 3R20 was 66.7 m/min compared to 30.4 m/min (P-value = 0.045). Moreover; the symmetry of walking with 3R20 was more than that with 3R15, based on the spatio- temporal gait parameters values (P-value <0.05).
The difference between the performances of the subjects with 3R20 and 3R15 knee joints was related to the walking speed, which improved while walking with 3R20 joint.
Seborrheic keratosis is a common, benign skin tumor. Numerous reports have shown its possibility of malignant transformation. This study was designed to demonstrate the occurrence of concomitant seborrheic keratosis and skin cancers.
Data was retrospectively reviewed from all patients with a diagnosis of seborrheic keratosis in pathology department of Alzahra Hospital and a private pathology laboratory in Isfahan, Iran over a 4-year period. We classified all demographic data and associated dysplasia or Bowen's disease and analyzed them by student-t or chi-square tests.
From all 429 specimens, 5 (1.2%) were found to be associated with Bowen's disease and one (0.2%) with mild dysplasia in squamous epithelium. All cases arose within the clinically, atypical seborrheic keratosis. More men were affected with lesions alone and with malignancy (230/423 (54.4%) and 5/6 (83.3%), respectively) compared to women. The average age of patients suffering from lesions with and without associated malignancy was 57 and 54 years, respectively. The common site of lesion alone was head and neck but lesions with malignancy involved lower extremities. The two lesions were significantly different in site of occurrence (p < 0.001).
Generally, although the association between seborrheic keratosis and skin malignancy appears to be accidental, it must always be in mind. Therefore, histopathologic examination of all seborrheic keratosis should be considered, especially when seborrheic keratosis has atypical clinical manifestations.
To determine disparity in mortality-related factors in 1-59 months children across Iran using hospital records of emergency units.
After designing and validating a national questionnaire for mortality data collection of children 1-59 months, all 40 medical universities has been asked to fill in the questionnaires and return to the main researcher in the Ministry of Health and Medical Education. Age and sex of deceased children, the type of health center, staying more than 2 h in emergency unit, the reason of prolonged stay in emergency, having emergency (risk) signs, vaccination, need to blood transfusion, need to electroshock and so on have also been collected across the country. There was also a comparison of children based on their BMI. Chi-square test has been applied for nominal and ordinal variables. ANOVA and t-student test have been used for measuring the difference of continuous variables among groups.
Mortality in 1-59 months children was unequally distributed across Iran. The average month of entrance to hospital was June, the average day was 16(th) of month, and the average hour of entrance to hospital was 14:00. The average of month, day and hour for discharge was July, 16, and 14:00, respectively. The hour of discharge was statistically significant between children with and without risk signs. More than half (54%) of patients had referred to educational hospital emergency units. There were no statistically significant differences between children with and without emergency signs. There were statistically significant differences between children with and without emergency signs in age less than 24 months (0.034), nutrition situation (P = 0.031), recommendation for referring (P = 0.013), access to electroshock facilities (P = 0.026), and having successful cardiopulmonary resuscitation (P = 0.01).
This study is one of the first to show the distribution of the disparity of early childhood mortality-related factors within a developing country. Our results suggest that disparity in 1-59 months mortality based on hospital records in emergency units needs more attention by policy-makers. It is advisable to conduct provincially representative surveys to provide recent estimates of hospital access disparities in emergency units and to allow monitoring over time.
