Assessment of urinary symptoms in children with dysfunctional elimination syndrome

Objective This study was organized to form a symptom scale for diagnosis and assessment of urinary and bowel symptoms in children with dysfunctional elimination syndrome (DES). Methods The study group included 81 children presented to our clinic with symptoms of DES like enuresis, abnormal voiding, urinary tract infection and urgency, between January 2003 and February 2004. Age matched 102 children with no history of urological complaints were randomly recruited from a public school as control group. Children with isolated, mono-symptomatic nocturnal enuresis were not taken to the study. All children and parents were requested to fill a 35-item questionnaire related to symptoms of DES. After statistical analysis, questions from the initial form that had a P-value <0.05 and an area under curve (AUC) value >0.6 were selected to form a final scale. Results The mean ages for study and control groups were 8.7 ± 2.5 and 8.3 ± 2.2 years, respectively (P = 0.236). The final scale was composed of 15 questions. The cut-off score for the presence of DES was determined as 7.5 (sensitivity 85.2%, specificity 93.1%, AUC value = 0.943) for the total population. When only the male population were concerned the cut-off score was 4.5 (sensitivity 93.8%, specificity 78%, AUC value = 0.913) while the cut-off score for the female population was 7.5␣(sensitivity 87.7%, specificity 94.2%, AUC value = 0.953). Conclusion Providing objective assessment of symptom severity, formation of a validated scoring system for children with DES might be a good tool for diagnosis, confirmation of treatment results and follow up. It might also be useful for screening purposes.     

Serum α-fetoprotein levels in liver steatosis

Background  

Nonalcoholic fatty liver disease (NAFLD) is a common disorder and becoming a leading cause of cirrhosis in the western world. The monitoring of the disease is challenging and the prognostic importance of α-fetoprotein (AFP) level elevation in NAFLD remains uncertain.     

High serum transforming growth factor beta 1 (TGFB1) level predicts better survival in breast cancer

The transforming growth factor beta 1 (TGFB1) is a regulatory cytokine with both tumor suppressor and tumor-promoting effects in breast cancer (BC) cell lines and tissue. Data about level of circulating TGFB1 and its prognostic significance in BC patients is conflicting. The objective of this study is to determine the clinical significance of the serum TGFB1 levels in BC patients. We enrolled 96 female patients with histopathologically diagnosed BC who did not receive chemotherapy (CT) or radiotherapy. Serum TGFB1 levels were measured by ELISA method and compared with 30 healthy controls. The mean serum TGFB1 level of BC patients was significantly higher than controls (0.08 vs. 0.04 ng/ml, p?<?0.001). There was no significant difference according to known disease-related clinicopathological or laboratory parameters. Serum TGFB1 level had a significant impact on overall survival in both univariate (p?=?0.01) and multivariate analysis (p?=?0.013). Serum TGFB1 level is elevated in BC patients and has a favorable prognostic value. However, it has no predictive role on CT response.     

Anaphylactic shock due to intravenous amiodarone

A 24-year-old male patient was admitted to the coronary intensive care unit with atrial fibrillation with rapid ventricular response. He was given amiodarone (Cordarone 150 mg i.v., Sanofi-Aventis) intravenous loading dose of 300 mg in 100 mL dextrose 5% in water (D5W) over 1 hour, followed by a maintenance dose of 900 mg in 500 mL D5W for infusion up to 24 hours. At the emergency department, the patient was conscious and cooperative; his pretreatment arterial blood pressure was 120/80 mm Hg, and the arrhythmic tachycardia was 145 per minute. After intravenous amiodarone loading and half an hour into maintenance infusion, extreme perspiration, hypotension (blood pressure immeasurable), and mild cyanosis developed. The patient was conscious; his auscultation and pulse were normal. He was given physiologic serum and dopamine support. Approximately an hour later, the blood pressure was measurable. Infusion was terminated because of suspicion of an allergic reaction to acetylsalicylic acid or amiodarone. The allergic reaction observed was attributed to acetylsalicylic acid and amiodarone; infusion was resumed when the clinical situation worsened during the maintenance infusion. Once again, the patient was given physiologic serum (2000 mL), dopamine (20 mg/kg per minute), and, additionally, 250 mg of methyprednisolone sodium succinate intravenous, whereby the clinical condition improved within 20 minutes. Anaphylactic shock cases due to amiodarone are rare; it is important to take a history of drug-mediated anaphylaxis before prescribing amiodarone. An addition to a review of the literature regarding treatment of amiodarone-related anaphylactic shock cases had not been reported before.     

Unusual complication of aortic dissections: intimo–intimal intussusception

Angiography with a pre-diagnosis of acute coronary syndrome was performed in a 76-year-old female patient presenting to another hospital with symptoms of chest pain and syncope. Upon determination of type III aortic dissection, the patient was referred to our clinic. On CT angiography, the ascending aortic diameter was 57 mm and no dissection flap was observed. There was a filling defect suggestive of intimo–intimal intussusception at the level of the aortic arch, occlusion of the left arteria carotid communis, and a double-channel aorta extending from the left subclavian artery to the iliac artery. On transoesophageal echocardiography, the ascending aorta was seen to be larger than normal and no dissection flap was observed. There were findings suggestive of haematoma and intimo–intimal intussusception at the proximal part of the aortic arch. The dissection flap causing occlusion in the vascular structures was resected. Supracoronary graft replacement of the ascending aorta was performed. Transoesophageal echocardiography is an invasive investigative method with high sensitivity and specificity for the diagnosis of intimo–intimal intussusception.     

Are chondrocytes damaged when rheumatologic inflammation is suppressed?

Aim: The use of biological agents (BAs) for treating diseases such as rheumatoid arthritis (RA), spondyloarthropathy, and systemic lupus erythematosus to reduce inflammation has been fruitful. Especially as part of the increasing number of studies on the intra-articular application of BAs, the effects of BAs on cartilage have been widely investigated. In the present study, the effects of rituximab, abatacept, and adalimumab, all approved antirheumatic agents, on human primary chondrocytes were investigated comparatively and on the molecular level through viability, proliferation, and toxicity analyses. Materials and methods: Osteochondral tissues from the distal femur and proximal tibia were resected during total knee arthroplasty from patients (n?=?3) with confirmed gonarthrosis in whom all medical or conservative treatments had failed. Standard human primary chondrocyte cell culturing was carried out. Immunophenotyping was performed on the cells that adhered to the flask, and their chondrotoxicity was observed using a flow cytometry device. Images of the cells showing chondrotoxicity were analyzed using invert and environmental scanning microscopes, and microimages were obtained. The MTT-enzyme linked immunosorbent assay was performed to observe the toxic effects of BAs on the proliferation of chondrocytes at 24 and 48?h. The results were analyzed using the number of cells and proliferation; statistical comparisons among the groups were carried out using one-way ANOVA. The alpha significance level was set at <0.01. Results: These pharmaceutical agents were chondrotoxic, especially on viability and proliferation (p?=?0.0000). Conclusion: BAs are generally used during active inflammation, and following the management of inflammation, their dosage should be determined taking into consideration their cellular-level toxic effects on chondrocytes.
