[show abstract] [hide abstract]
ABSTRACT: This study planned for finding the agreement DXA and quantitative ultrasound (QUS) of phalanx in osteoporosis diagnosis and cut off point of QUS for osteoporosis diagnosis in postmenopausal women. In 180 postmenopausal women, BMD of axial regions with DXA (DPX-MD, GE, Lunar, USA) and phalanx with QUS (DBM-Sonic 1200) measured. Agreement of methods and cut off for QUS in defining osteoporosis obtained. Prevalence of osteoporosis with DXA was 28.8% (18.3% in L2-L4 and 3.9%-7.8% in femoral regions) and in 28.9% with QUS. Agreement of them (Kappa score) was 0.317 for spine and 0.036-0.068 for femoral regions. T-score= -2.0 was the cut off of QUS in spinal osteoporosis diagnosis (sensitiv-ity=78.8% and specificity= 55.9%). We could not find cutoff point for osteoporosis in femoral regions. This means that QUS of phalanx is not a good replacement for DXA, but it can be used as a screening method for osteoporosis.Iranian journal of public health 01/2013; 2004(A supplementary issue on Osteoporosis). · 0.24 Impact Factor -
Article: Relation of Reproductive Factors and Heel Quantitative Ultrasound Parameters in Normal Women of Tehran
[show abstract] [hide abstract]
ABSTRACT: Quantitative Ultrasound (QUS) is a noninvasive, inexpensive and portable method for bone densitometry. It may measure some other parameters in addition to BMD, like elasticity and micro architecture. This study designed to determine the rela-tion between reproductive factors and calcaneus QUS parameters in normal women of Tehran. BMD of heel in 151 normal women, 20-72Y/O (participator of Iranian Multi center Osteoporosis Study) was assessed using Achilles+ (GE, Lunar Cor-poration, USA). After assessment of normal values, Stiffness Index percentiles acquired. With consideration of correlation between variables, multiple regression analysis was used. Mean±SD values of Speed of Sound (SOS), Broad Band Ultra-sound Attenuation (BUA) and Stiffness Index (SI), was 36/75±1527/25, 121/42±15/1, 94/46±17/92, respectively. Parame-ters decreased with age (P<0/01). Years of menopause significantly related with QUS parameters and age of menopause significant related with SOS and SI. Results show effectiveness of some reproductive factors on QUS parameters.Iranian journal of public health 01/2013; 2004(A supplementary issue on Osteoporosis):76-81. · 0.24 Impact Factor -

Article: Epidemiology of absconding from an Iranian psychiatric centre.
[show abstract] [hide abstract]
ABSTRACT: Absconding by psychiatric patients from acute psychiatric wards has been a significant problem for some time. This study was conducted to identify the incidence rate of absconding in a psychiatric hospital and some of the characteristics of patients who had escaped from hospital in year 2006. In this descriptive cross-sectional study, all of absconds in our centre have been registered in the period of 9 months. We assessed patients' age, gender, marital status, hospital stay, substance abuse, psychiatric diagnosis and site of absconding. A total of 43 cases of absconding have been registered in this period, attempted by 35 patients, with the incidence rate of 3% in our centre. The mean age of absconders was 31.7 years; 95.3% of absconds were made by men; 67.4% were single; 37.4% absconded through the main door; 62.8% of our absconders had bipolar mood disorder or schizophrenia; mean in hospital stay before absconding was 18.4 days; and 53.5% of absconds were attempted by substance users. Absconders utilize a significant portion of hospital resources and have an adverse effect on ward milieu. It seems that the patients who are more prone to abscond are male, young, single, addict, with the diagnosis of bipolar mood disorder or schizophrenia and patients who are admitted not long ago.Journal of Psychiatric and Mental Health Nursing 04/2009; 16(2):153-7. · 0.80 Impact Factor -
Article: Hyperglycemia in acute aluminum phosphide poisoning as a potential prognostic factor.
[show abstract] [hide abstract]
ABSTRACT: Aluminum phosphide (AlP) is a solid fumigant widely used in Iran as a grain preservative. When reacted with water or acids, AIP produces phosphine gas, a mitochondrial poison that interferes with oxidative phosphorylation and protein synthesis. Poisoning by AIP is one of the most important causes of fatal chemical toxicity in Iran. There are few studies in the medical literature addressing prognostic factors associated with AlP poisoning. In this prospective study conducted across a 14-month period commencing on 21st March 2006, we enrolled all patients admitted to the ICU of Loghman-Hakim Hospital Poison Center (Tehran, Iran) with AIP poisoning, no history of diabetes mellitus diagnosed before hospitalization, and normal body mass index. We recorded patient-specific demographic information, blood glucose level on presentation (before treatment), arterial blood gas (ABG) analysis, time elapsed between ingestion and presentation, ingested dose, duration of intensive care admission, and outcome data related to each presentation. We enrolled the group of patients who survived the intoxication as a control group and compared their blood glucose levels with those who died because of AlP poisoning. Data were analyzed by Statistical Product and Service Solutions (SPSS) software (Version 12; Chicago, Ilinois, USA) using logistic regression, Pearson correlation coefficient and Student's t-test. P values of 0.05 or less were considered as the statistical significant levels. Forty-five patients (21 women and 24 men) with acute AlP poisoning were included in the study. The mean age was 27.3 +/- 11.5 years (range: 14-62 years). Thirteen patients survived (29%) and 32 expired (71%). AlP poisoning followed deliberate ingestion in all patients. The time elapsed between ingestion and arrival at the hospital was 3.2 +/- 0.4 h. There was no significant difference between survived and non-survived groups according to age, gender, and time to treatment. However, the difference between mean blood glucose levels in survived (143.4 +/- 13.7 mg/dL) and non-survived (222.6 +/- 20 mg/dL) cases was statistically significant (P = 0.021). There was no significant correlation between blood glucose level and time to treatment, age, gender, pH, HCO3 concentration, and ingested dose. Twenty-three (71.9%) of non-survived and four (30.8%) of survived patients had a blood glucose level greater than 140 mg/dL. After adjusting according to age, gender, ingested dose, pH and HCO3 concentration The odds ratio for hyperglycemia as a risk factor for death was 5.7 (CI of 1.4-23.4). In our study, patients who succumbed to AIP poisoning had significantly higher mean blood glucose levels than those who survived. This correlation of hyperglycemic effect and mortality suggests that it may be useful in guiding risk assessment and treatment of AIP poisoning. Management of hyperglycemia may have a useful role in treatment of these patients by allowing increased entrance of glucose into cells and reducing oxygen consumption.Human & Experimental Toxicology 08/2008; 27(7):591-5. · 1.77 Impact Factor -
Article: Assessment of bone structure in renal transplant recipients: comparison of phalangeal qualitative ultrasound and dual x-ray absorptiometry.
[show abstract] [hide abstract]
ABSTRACT: According to the WHO criteria many renal transplant patients display osteopenia or osteoporosis. Dual-energy X-ray absorptiometry (DXA), the standard method to assess bone mineral density (BMD), is not always available. Quantitative ultrasound (QUS) of the phalanx is an inexpensive, mobile, and radiation-free diagnostic alternative. Few data address the correlation of this method with DXA in renal transplant patients. This study assessed the value of QUS compared with DXA to detect changes in bone structure among renal transplant recipients. This cross-sectional study of 42 patients (22 women), of mean age 40.2 +/- 11.9 years, mean time since transplantation of 2.8 +/- 2.9 years, and mean dialysis time of 8.55 +/- 10.26 months, included. DXA for bone mineral densitometry of the hip (neck and total femur) and spine as well as QUS to measure the amplitude-dependent speed of sound (Ad-SOS) in the phalanx. Using DXA, osteoporosis was observed in 19% of all patients: 9.5% in femoral neck, 9.5% in total region of the femur, and 9.5% in the spinal region. The sensitivity of Ad-SOS for osteoporosis diagnosis in the above regions were 100%, 75%, and 25%, respectively; its specificity was 45%, 43%, and 37%, respectively. There was no significant relation between the two methods for diagnosis of osteoporosis in any region. QUS of phalanx can be recommended for osteoporosis screening in renal transplant patients. Those suspected of osteoporosis should be examined by additional DXA measurements in order to establish the diagnosis.Transplantation Proceedings 10/2005; 37(7):3112-5. · 1.00 Impact Factor -
Article: Bone Mineral Density in Iranian Kidney Graft Recipients and Its Relation to Biochemical and PTH Serum Levels
[show abstract] [hide abstract]
ABSTRACT: Little is known about relation of transplantation and bone. We conducted a study to find out the frequency and predictors of osteoporosis in kidney transplanted patients in Iran. DEXA (DPX-MD, GE, Lunar corporation, USA) used for BMD of 61 kidney transplanted patients. Calcium, phosphate, alkaline phosphatase, BUN, creatinine and PTH, were also measured. Fourty four percent of patients were men (27). Mean±SD of age of men and women was 44.3±10.44 and 40/7± 13.77, respectively. Mean±SD of transplant duration was 33.9± 33. 2 months Mean±SD of dialysis time was 12±14 months. 29.5% of patients had osteoporosis. Osteoporosis was significantly higher in subjects with BMI less than 19 kg/m2 (P= 0.007). Alkaline phosphatase had a negative relation with osteoporosis in neck (P= 0.001). Other parameters had no significant relationship with osteoporosis. High prevalence of osteoporosis found in Iranian kidney graft recipients. Screening and therapeutic intervention in these patients is urgently needed.Iranian J Publ Health. 01/2004; -
Article: Opium use in a rural area of the Islamic Republic of Iran.
[show abstract] [hide abstract]
ABSTRACT: Because of its geographic proximity to the major drug production centres, there is easy access to narcotic drugs in the Islamic Republic of Iran despite efforts by governmental and nongovernmental organizations. Using a structured questionnaire as a basis for conversation, local health workers interviewed 310 residents of a rural area in Babol province about opium use. The self-reported rate of opium use, adjusted due to a bias in the sex ratio of the sample, was 8.9%. All the 42 opium users reported opium use at least 2-3 times per week in the previous 3 months. Opium was smoked by 95.2% and taken orally by 4.8%; there was no injecting use. There was no reported use of other substances, including alcohol. There was a statistically significant relationship between opium use and male sex, unemployment and cigarette smoking.Eastern Mediterranean health journal = La revue de santé de la Méditerranée orientale = al-Majallah al-ṣiḥḥīyah li-sharq al-mutawassiṭ 15(2):425-31. -
