    ABSTRACT: Background: Hypercalcemia and severe osteolytic lesions are rare complications of acute lymphoblastic leukemia (ALL) in childhood, and those cases share similar clinical features. Similarly, hypercalcemia is a rare feature in adult ALL. Here, we report an uncommon case of an adult patient with relapsed precursor B ALL (pre-B ALL) who developed multiple osteolytic lesions and hypercalcemia. Case description: A 24-year-old male patient, diagnosed with pre-B ALL, was admitted in our hospital due to severe lumbar pain. After reviewing laboratory, radiological and clinical findings, the patient was diagnosed as having relapse of a mixed phenotype acute leukemia, according to bone marrow aspiration (9% blasts) and cytogenetic analysis, with multiple osteolytic lesions in all lumbar vertebrae, sacrum and ilium and severe hypercalcemia (13.3 mg/dL). Thus, FLAG-IDA rescue therapy and hydration plus furosemide, corticoids and bisphosphonates were administered. Despite initial amelioration, his hematological condition deteriorated and he died due to severe sepsis as a result of severe immunosuppression. Conclusion: Two possible mechanisms have been suggested for hypercalcemia in hematological malignancy, either the leukemic infiltration or the paraneoplastic production of a variety of humoral factors and proinflammatory cytokines. However, hypercalcemia and severe osteolytic lesions are rare features in ALL adult patients and their combination may be indicator of poor prognosis. Hippokratia 2015, 19 (1): 78-81.

    ABSTRACT: Background: Ewing's sarcoma localized to foot is extremely rare. Local control is mandatory because of the aggressive nature of the tumor. Therapeutic options for these local tumors include neoadjuvant chemotherapy followed by surgery. Description of the case: A 17-year-old female patient presented with a 6-month history of progressive swelling and intermittent pain of the left great toe. Plain radiography and magnetic resonance imaging revealed an expansile mass that had originated from the proximal phalanx of the great toe and was destructing and surrounding the distal phalanx. Her erythrocyte sedimentation rate and serum lactate dehydrogenase levels were slightly elevated. Distant metastasis was not detected. The patient underwent an open biopsy, which confirmed the diagnosis of Ewing's sarcoma. She was treated with neoadjuvant chemotherapy and disarticulation above the metatarsophalangeal joint. She received adjuvant chemotherapy following the operation. The patient died 50 months after the operation as a result of disseminated disease. Conclusion: The distal phalanx of the foot is an extremely rare site for the development of Ewing's sarcoma. As local control is important to avoid dissemination of the disease, neoadjuvant chemotherapy followed by amputation or disarticulation of the affected digit and subsequently adjuvant chemotherapy may be favorable modality for increasing the patient's duration of survival.

    ABSTRACT: Background: The diagnosis of acute abdomen in the emergency setting, still remains a challenging problem. In these cases timely diagnosis and management is of great importance, while the anesthetic risk is high. The combination of the risk of an open laparotomy and the relative high likelihood of negative findings when performed, creates the need for a better approach. The alternative actually exists since 1911 when Eruheim made the first gasless laparoscopy. The aim of this study is to put back into the spotlight, gasless laparoscopy in the differential diagnosis of acute abdomen and to underline the advantages of this simple, cheap and very useful technique, especially in patients that require prompt diagnosis and have relative or absolute contraindications to general anesthesia or pneumoperitoneum. Methods: This study included 49 patients that were managed with gasless laparoscopy for the diagnosis of acute abdomen, from 2011 to 2013. Two techniques were used: the mechanical lift of the anterior abdominal wall and the LapVision device. Results: From the 49 patients included in the study, 41 were diagnosed with gasless laparoscopy while in eight the results were uncertain or there wasn't any pathology involved. With both techniques used, sample of the intraperitoneal fluid or biopsy could be obtained. Conclusion: The gasless technique for laparoscopy is an extremely useful mean of diagnosis in emergency conditions, or for patients with contraindications to undergo laparoscopy by pneumoperitoneum. Requiring only local or regional anesthesia, this technique could easily find application in diagnosis and treatment, while avoiding unnecessary laparotomies. Hippokratia 2015, 19 (1): 69-72.

    ABSTRACT: Background: Different treatment options for patients with prostate cancer (PCa) are applicable after stratifying patients according to various classification criteria. The purpose of our study is to evaluate the revised Epstein's criteria for insignificant PCa prediction in a Greek subpopulation. Methods: During a 4-year-period, 172 Cretan patients were submitted to radical retropubic prostatectomy in our institution. 23 out of them met the revised Epstein's criteria for the presence of clinically insignificant PCa (clinical stage T1c, prostate specific antigen density < 0.15 ng/ml/g, absence of Gleason pattern 4-5, <3 positive biopsy cores, presence of <50% tumor per core) during pre-treatment evaluation and were retrospectively included in the study. Post-surgery outcomes were evaluated including pathological stage, surgical margins and Gleason score upgrade. Results: Organ confined disease and insignificant PCa were predicted with a 74% and 31% accuracy, respectively. These figures are remarkably lower than those derived from similar studies worldwide. Conclusions: Due to the high variation in the revised Epstein's criteria prediction accuracy observed worldwide, the development and implementation of novel tools/nomograms with a greater predictive accuracy is still warranted.

    ABSTRACT: Nesfatin-1 is a peptide secreted by peripheral tissues, central and peripheral nervous system. It is involved in the regulation of energy homeostasis related with food regulation and water intake. Nesfatin-1 can pass through the blood-brain barrier in both directions. It suppresses feeding independently from the leptin pathway and increases insulin secretion from pancreatic beta islet cells. That is why nesfatin-1 has drawn attention as a new therapeutic agent, especially for the treatment of obesity and diabetes mellitus. Its effects on nutrition have been studied in more detail in literature. On the other hand, its effects on other physiological parameters and mechanisms of action still need to be clarified. Synthesizing the research on nesfatin-1 can help us better understand this field. © 2015, Lithografia Antoniadis I - Psarras Th G.P. All rights reserved.

    ABSTRACT: Background: A Vitamin D Receptor gene (VDR) polymorphism, rs10735810 (Fok1), has been associated in the past with idiopathic short stature (ISS) in a linkage study. We have investigated the association of the same, as well as a different polymorphism in the same gene [rs731236 (Taq1)] with ISS, in an independent study in Greek children. Methods: The VDR rs10735810 (Fok1) and rs731236 (Taq1) polymorphisms were genotyped in a group of ISS children (n= 47) and an age and sex-matched group of normal height children (n= 60) from northern Greece. Genotyping was accomplished through established PCR-RFLP methods. Results: An association trend of rs10735810 with ISS was observed, with the TT (ff) genotype being apparently underrepresented among ISS children compared to controls (p= 0.076; OR= 0.165, 95% CI= 0.025-1.094). Conclusions: The above results, together with recent evidence related to the functionality of the rs10735810 polymorphism, cannot exclude an involvement of VDR in the pathogenesis of ISS.

    ABSTRACT: Background: Urate through NOD-like receptor family, pyrin domain containing 3 (NLRP3) inflammasome-dependent caspase-1 activation stimulates macrophages to secrete inteleukin-1β (IL-1β). Urate also enhances adaptive immunity indirectly through its effect on antigen presenting cells. In this study, the direct effect of urate on isolated primary human T-cells was evaluated. Methods: Isolated T-cells were cultured with or without monosodium urate crystals in the presence or not of the NLRP3 inflammasome inhibitor glyburide. Activated cleaved caspase-1 was assessed by means of western blotting, whereas caspase-1 activity was measured colorimetrically in the cell lysates. IL-1β was measured in the supernatants by means of enzyme-linked immunosorbent assay. T-cell proliferation was assessed by means of bromodeoxyuridine labelling and immunoenzymatic detection. Results: Urate induced caspase-1 activation and IL-1β release by T-cells. It also induced proliferation of T-cells. Glyburide inhibited urate-induced caspase-1 activation, IL-1β secretion and proliferation. Conclusions: Urate, a well defined danger signal, stimulates directly human T-cells in a NLRP3 infmmasomela-dependent way. The subsequent IL-1β secretion could enhance inflammation, whereas expansion of T-cell clones could facilitate a subsequent adaptive immune response. Hippokratia 2015, 19 (1): 41-46.

    ABSTRACT: Background: Gastrointestinal stromal tumors (GISTs) represent 85% of all mesenchymal neoplasms that affect the gastrointestinal track. Aim of this study is to report a case series of 18 GISTs treated surgically in a single centre and to discuss the diagnostic and therapeutic issues regarding these tumors. Case series: A retrospective search of the unit's medical records from 2002 to 2014 was carried out, to collect all cases diagnosed and treated for GISTs. Demographics and clinical features was obtained for all relevant cases. Results: Eighteen cases (18) of GIST were identified. Eleven tumors were located in the stomach, 3 tumors in the duodenum and 4 tumors in the jejunum. The mean age at diagnosis was 62.5 (range 42-81) years, while the male to female ratio was 1.57/1 (11 males/7 females). Patients presented with a variety of symptoms and all underwent surgery. The 5-year-survival rate of these patients was 50%. Conclusion: Due to non-specific presentation of GISTs, initial diagnosis of these tumors may be delayed. High clinical suspicion and knowledge of their characteristics are essentials in order to achieve an early diagnosis and lead patients to surgery as soon as possible. Hippokratia 2015, 19 (1): 73-75.

    ABSTRACT: Background: Progressive lung disease is the main cause of clinical deterioration and mortality in cystic fibrosis (CF) patients. Being able to assess the effectiveness of interventions is very significant. Objectives: To assess the response to intravenous (IV) treatment among CF patients, using forced expired volume in 1st second (FEV1) and Lung Clearance Index (LCI) as outcome measures and to compare the effect of IV treatment on lung function and LCI between CF children being treated on a regular basis, or in case of a pulmonary exacerbation. Subjects and Methods: Thirty-two CF patients (15 males) with mean age 9.90 (range: 2-23) years, performed spirometry and multiple breath washout (MBW) before and one month after IV antibiotic treatment. Nineteen patients received a course of elective treatment (group A) and 13 received IV antibiotic regimens for an acute exacerbation (group B). Results: Statistically significant differences after treatment were seen in LCI (p≤0.001), and Forced Expiratory Flow (FEF) z-scores (p<0.05). FEV1 did not change significantly after drug intervention. Dividing patients into two groups, only LCI showed significant change (p<0.05), when treatment was administered on a regular basis. Patients being treated for an acute pulmonary exacerbation showed significant improvement in most of the lung function parameters: LCI (p=0.0001), FEV1% (p=0.05), FEV1 z-score (p=0.033) and FEF25-75 (p=0.046). The mean LCI difference was significantly greater in group B compared to group A (p=0.001). Conclusion: LCI is more sensitive marker than FEV1 to assess the effect of IV antibiotic treatment among CF children. IV antibiotics are more effective on lung function parameters, when they are administered for an acute exacerbation, than when they are given on a regular basis. © 2015, Lithografia Antoniadis I - Psarras Th G.P.

    ABSTRACT: Aim: This study aims to investigate the inducing effect of subminimum inhibitory concentrations of macrolide antibiotics on Mycoplasma pneumoniae (M. pneumoniae) resistance to drugs. Materials and methods: One M. pneumoniae reference strain M129 (ATCC 29342) and 104 clinical isolates were incubated at 37C for 6-8 days. Genomic DNA of M. pneumoniae was extracted using TIANamp Bacteria DNA kit and amplified by polymerase chain reaction (PCR). Results: Ten sensitive isolates obtained from 104 M. pneumoniae clinical isolates were induced by subminimum inhibitory concentrations of macrolide antibiotics. Among them, three were found to possess mutations in L4 and L22 ribosomal proteins. Two cases carried simultaneously the C162A and A430G mutations of L4 and the T279C mutation of L22. In addition, one case had only the A209T mutation of L4. Conclusions: Repeated in vitro exposure to subminimum inhibitory concentrations of macrolide antibiotics could induce selective mutations in ribosomal genes of M. pneumoniae clinical isolates that cause resistance to macrolide antibiotics.

    ABSTRACT: Background: The aim of this study was to investigate the disease characteristics of children with juvenile idiopathic arthritis (JIA) in southeast Turkey. Methods: The International League of Associations for Rheumatology (ILAR) criteria were used to diagnose JIA. Hospital records of the Pediatric Rheumatology Unit, of the Dicle University Hospital, were reviewed retrospectively and demographic, clinical and laboratory data were recorded. Results: Totally 213 children (103 boys, 110 girls), with an age range of 1.6-18 years were enrolled. The mean age of the disease onset was 8.1 years. Polyarticular type was the most common (42.3%) presentation. The frequencies of other JIA subtypes were as follows: oligoarticular 37.1%, systemic 8.9%, enthesitis-related arthritis (ERA) 10.8% and psoriatic arthritis 0.9%. The knees (74.2%) and ankles (54.0%) were the most commonly affected joints. Uveitis was found in 4.2% of patients. Anti-nuclear antibodies were positive in 11.7% and HLA-B27 in 2.8% of patients. Active disease was seen in 57 (26.7%) patients at the last visit. Conclusion: In the present study, polyarticular JIA was the predominant subtype and there were fewer patients with positive ANA or uveitis compared to previous studies.

    ABSTRACT: Background: Respiratory dysfunction often persists in post intensive care unit (ICU) patients and intermediate care facilities have been established to ensure the continuous of appropriate care. Methods: The data of patients with difficult weaning from mechanical ventilation admitted to a respiratory intermediate unit (RIU) attached to a pulmonary department of a General Hospital, were retrospectively analyzed. Clinical characteristics, weaning from mechanical ventilation and tracheostomy, ICU readmission and RIU mortality were examined over a period of 18 years (1993- 2010) that was randomly divided into three six-year-periods. Results: A total of 548 patients (age 56.7±17.9 years) [mean ± standard deviation (SD)], of whom 80% with tracheostomy in place and 37.6% with pressure ulcers, were examined. The ICU stay was 30.1±24.7 days (mean ± SD) and increased over time (p<0.05). Patients' baseline disorders were: chronic respiratory disease (41.3%), chronic cardiovascular diseases (10.6%), neuromuscular disease (22.8%) and miscellaneous (25.3%). The length of RIU stay (22.8±19.5 days) was constant over the examined periods but an increase in age and maintenance of tracheostomy were observed; 80% of patients were liberated from mechanical ventilation and 58.5% from tracheostomy, whereas the RIU mortality was 15%. Conclusion: In their vast majority patients with chronic respiratory failure, who were admitted to RIU,were weaned from mechanical ventilation, although in a substantial percentage the maintenance of tracheostomy was mandatory after discharge.

    ABSTRACT: Background-objective: No study has focused on the difference in efficacy of maintenance therapy between patients with new-onset and recurrent gastroesophageal reflux disease (GERD). The aim of this study is to reveal this point. Methods: Endoscopically proven GERD patients who had completed 8-week initial therapy were sequentially randomized to continuous arm (Omeprazole 20mg od) or on-demand arm (Omeprazole 20mg on-demand). Patients filled in daily symptoms and tablet usages for 24 weeks. Patients underwent upper GI endoscopy at 24 weeks. Symptom relief was defined as no symptoms for>6 days during a week. The numbers of patients who achieved symptom relief and mucosal healing were compared between the new-onset and recurrent groups in the continuous arm and in the on-demand arm, respectively. Results: Among new-onset GERD [n=82 (continuous: 42 patients, on-demand: 40)], continuous arm achieved significant symptom-relief than in on-demand arm at 4*,5*,6** and 17*week. Among recurrent GERD [n=36(continuous: 17 patients, on-demand: 19)], continuous arm achieved significant symptom-relief at 1**,2*,3*,4*,5**,7**,8**,17* and 18* week, respectively (*<0.05,**<0.01). The number of healed patients was significantly higher in new-onset group (60/68, 88.2%) than in recurrent group (17/30, 56.7%) (<0.01). Conclusion: Since therapeutic response during maintenance therapy was poor in recurrent GERD, continuous therapy is recommended in order to maintain symptom-relief and mucosal healing.

    ABSTRACT: Background: West Nile virus (WNV) causes to humans a variety of symptoms, from asymptomatic infection to severe neuroinvasive disease. In a previous study, it was shown that WNV IgM antibodies persisted in three of 26 (12%) patients, nine months after onset of the symptoms. The aim of the present study was to test 10 of these patients, three years post-infection for probable persistence of IgM antibodies and to investigate their IgG antibody patterns. Material and methods: In summer 2013 serum samples were collected from 10 persons who were infected with WNV in 2010; 6 of them had a neuroinvasive disease. The three persons with detectable WNV IgM antibodies, nine months after onset of the symptoms, were included in the study. All samples were tested by ELISA in parallel with their stored paired samples taken in 2011. The positive results were confirmed by neutralization test. Results: WNV IgM antibodies were still detectable in the three persons, while high levels of WNV IgG and neutralizing antibodies were present in nine of the 10 persons, regardless the involvement of the nervous system. Conclusions: WNV IgM antibodies persist for more than three years in 12% of patients with WNV infection, while WNV IgG antibodies persist and even increase their levels, regardless the involvement of the nervous system, suggesting that the immune response in the symptomatic WNV infections is strong and long-lasting.
