Evaluation of fetal serum thiol/disulphide homeostasis in deliveries complicated by nuchal cord

Aim: To investigate the serum thiol/disulphide homeostasis in deliveries complicated by nuchal cord (NC) and to compare the results with healthy deliveries (without NC).

Methods: This prospective controlled study included 48 pregnant women complicated by NC and 48 similar gestational aged healthy pregnant women during labor. Fetal umbilical cord serum samples were collected during labor and the thiol/disulphide homeostasis was measured by using an automated assay method. The patients were followed up until end of the delivery and perinatal outcomes were recorded.

Results: Fetal umbilical cord native thiol, total thiol, and disulphide levels as well as disulphide/native thiol and disulphide/total thiol ratios are impaired in labor with the presence of NC. There were no statistically significant differences in terms of maternal and gestational age at delivery and maternal number of gravida and parity, fetal gender, fifth Apgar scores <7, mode of delivery and fetal birth weight between groups. The group of patients with NC had higher emergency C/S numbers indicated for fetal distress and lower first Apgar scores <7. There were no neonatal intensive care unit admissions among these babies.

Conclusions: Maternal serum thiol/disulphide homeostasis reflect transient effects of NC during labor regardless of labor type. Vaginal delivery can be safely and successfully performed in pregnancies complicated with NC.     

Importance of TNF-related apoptosis-inducing ligand in pathogenesis of interstitial cystitis

Introduction  

Although interstitial cystitis is an inflammatory disease, its etiopathogenesis is not clearly understood. The objective of the present study is to investigate the distribution of TNF-related apoptosis-inducing ligand (TRAIL) and its receptors in bladder biopsy samples of patients diagnosed with interstitial cystitis and the role of TRAIL in the pathogenesis of interstitial cystitis.     

Occupational asthma, eosinophil and skin prick tests and serum total IgE values of the workers in a plant manufacturing rose oil

This study was aimed to determine the rate of occupational asthma (OA) in workers at a rose extracting plant. Specific clinical tests of 52 workers, randomly chosen from four local rose extracting plants, were statistically compared with the test results of 30 local control subjects of similar age and sex as the plant workers, but who had never worked in such a plant. There were no significant differences in pulmonary function tests (FVC, FEV1, FEV1/FVC, PEFR) between the control and test groups. Significantly higher serum total IgE values (p < 0.0001) were observed for the test subjects (239.08+/-240 IU/ml) compared to the control subjects (81.33+/-61.45 IU/ml). There were also significant differences (p < 0.0001) in the number of eosinophils between the control and test groups, with corresponding mean values of 2.28+/-2.75% and 0.73+/-1.72%, respectively. A specifically prepared skin prick test using a rose allergen (Rosa domescena) was positive for 53.84% in the test subjects whereas only 5.33% positive test results were seen in the control group. We have demonstrated the involvement of Rosa domescena pollen in occupational allergy, through IgE-mediated hypersensitivity. It was concluded that the workers of a rose oil extracting plant are more susceptible to the rose pollens.     

The value of tartrate resistant acid phosphatase (TRAP) immunoreactivity in diagnosis of hairy cell leukemia

Hairy cell leukemia (HCL) is a rare chronic B-cell lymphoproliferative disorder characterized by splenomegaly, pancytopenia, and circulating atypical lymphocytes with circumferential cytoplasmic projections. We investigated the specificity and the sensitivity of anti-TRAP antibody immunoreactivity in 57 cases of HCL. We found that there is a statistically highly significant difference between TRAP immunoreactivities of the study and the control groups, and HCL can be diagnosed by TRAP immunoreactivity in bone marrow trephine biopsy materials with a specificity of 98.27 % and a sensitivity of 100%.     

The use of transdermal fentanyl in chronic non-malignant pain

Twelve non-malignant pain patients were followed-up for pain, improvement in the quality of life, satisfaction for pain therapy and side effects for a mean of 95.25 days with the use of transdermal fentanyl (TDF). During this period a mean of 32.04 mg/gr TDF was used. While the score of pain at rest was decreased by 52.6%, mean pain score on movement was decreased by 45.2% (p= 0.002). Quality of sleep improved and impairment of daily living by pain was decreased significantly (p= 0.002). Satisfaction by the pain therapy was 83.3% and the most common side effect was nausea (16.8%). TDF may be a good alternative in the therapy of chronic non-malignant pain if patients were selected carefully.     

Plasmacytoma of the temporal bone: management with a combination of surgery and radiotherapy

The diagnosis of solitary plasma cell neoplasm is based on clinical, radiological and laboratory findings and it can be accepted as the precursor lesion of multiple myeloma as spread of disease occurs in 30-50% of affected patients. However, solitary plasmacytoma of the temporal bone is a rare pathology. We present an interesting case of plasmacytoma of the temporal bone which was controlled by a combination of surgery and radiotherapy.     

Comparison of the effects of enalapril and losartan on posttransplantation erythrocytosis in renal transplant recipients: prospective randomized study

BACKGROUND: The aim of this prospective randomized study was to compare the safety and efficacy of enalapril (E) and losartan (L) in the treatment of posttransplantation erythrocytosis and the effect of the ACE genotype on response to therapy. METHODS: Twenty-seven (24 male and 3 female, mean age 34+/-8 years) renal transplant recipients with erythrocytosis were treated either with E (15 patients) (10 mg/day) or L (12 patients) (50 mg/day) for 8 weeks. RESULTS: The hemoglobin levels were significantly decreased in the L (17.1+/-0.7 to 15.9+/-1.3 g/dl, P=0.01) and E groups (17.4+/-1.1 to 14.9+/-2.2 g/dl, P=0.001). Among the responders who discontinued treatment, there was a trend for longer time to relapse in the L group (7.38+/-3.75 months; 95% confidence interval: 0.03-14.7) compared with the E group (2.75+/-0.70 (95% confidence interval: 1.37-4.13) (P=0.11). Decrease in hemoglobin was more prominent with E compared with L (-3.26+/-0.65 vs. -1.70+/-0.39 g/dl, P=0.05). Decrease in hemoglobin levels between DD and non-DD genotype groups was similar (-2.0+/-1.5 vs. -1.7+/-2.3 g/dl, P=0.69). CONCLUSIONS: Enalapril caused a greater decrease but faster relapse in hemoglobin levels compared with losartan in patients with posttransplantation erythrocytosis. The DD type polymorphism had no effect on response.
