Body mass index percentiles among adolescent girls living in Edirne, Turkey

BACKGROUND: Body mass index (BMI) is the simplest way to measure obesity; therefore, it is chosen by many authorities as a screening method for adolescent obesity. Body mass index is positively correlated with the complications of childhood and adolescent obesity, such as hypercholesterolemia, insulin resistance, hyper-tension and long-term development of cardiovascular diseases. The aim of the present study was to produce percentile curves for bodyweight, height and BMI in a representative sample of adolescent girls living in urban and rural areas of Edirne, Turkey, and to compare these percentile curves with curves from other countries. METHODS: The present study was a cross-sectional study, including a representative sample of 1687 adolescent girls from rural and urban areas of Edirne, who were evaluated between May and July 2001. Bodyweight and height were measured using standard procedures. Body mass index (kg/m2) was calculated as the ratio of bodyweight to body height squared. Smoothed percentiles for these variables were calculated using polynominal regression models. Crude weight, height and BMI percentile values, as well as smoothed percentile curves are presented. RESULTS: Body mass index, weight and height reference curves for adolescent girls were produced. When we compared the BMI values of subjects in the present study with those of other countries, 85th and 95th percentiles of BMI in the present study were found to be generally lower than those for other ethnicities. CONCLUSION: Our findings show ethnic differences in BMI among adolescent girls. It will be usefull for each country to produce its own BMI percentiles.     

Serum levels of C3 and Factors I and B in minimal change disease

Abstract Background: Relapses are an important problem in minimal change disease, which accounts for most of the cases of childhood nephrotic syndrome. Because of defects in the humoral immune system, patients are predisposed to infection in nephrotic syndrome and infection is the most important complication that determines mortality and morbidity.
Methods: In this study, serum levels of Factors I and B and C3 were studied to evaluate the relationships between nephrotic syndrome and infection in 17 children with nephrotic syndrome (24–96 months of age) and 10 healthy children (27–84 months of age).
Results: Serum levels of Factors I and B were found to be lowered in the active disease group compared with the control group. These values were lowest for the infection group. Although it was observed that these values increased with steroid treatment, they did not reach normal levels. The parameters in remission were not different from the parameters in the control subjects. The serum level of C3 was found to be high during the active disease state and returned to normal levels during remission.
Conclusions: The patients with active minimal change disease had infections such as peritonitis, septicemia and urinary tract infection because of low concentrations of Factors I and B in their sera.     

Renal functional reserve in insulin dependent diabetic children

Abstract Background: Microalbuminuria has been shown to be predictive for clinical diabetic nephropathy. Renal functional reserve (RFR), as a response to protein loading in a short period of time, is a parameter to assess the ability of kidneys to increase the glomerular filtration rate (GFR). The aim of this study was to predict the early phase of diabetic nephropathy by measuring urinary albumin level and RFR capacity in patients with insulin-dependent diabetes mellitus (IDDM).
Methods: Twenty-two patients with IDDM were studied: 11 with a disease duration of less than 5 years (group 1) and 11 with a disease duration of more than 5 years (group 2). As the control group, 15 healthy children (group 3) were included in the study. At the beginning of the study, glucose was measured and the urinary albumin/creatinine ratio was calculated. Average glycosylated hemoglobin (HbA₁c) over 1 year was determined. After protein loading (red meat containing 2 g/kg of protein), the creatinine clearance was calculated at each hour for a duration of 4 h. The RFR was accepted as the peak percentage increase in GFR over the baseline value.
Results: Although metabolic control in group 2 was better, the RFR in group 2 was significantly lower than in group 1 (P < 0.05). Urinary microalbumin levels between the groups did not differ (P < 0.05). In two patients in whom microalbuminuria was detected, the RFR was much lower.
Conclusions: Detecting lower RFR levels in patients with normal urinary albumin excretion, as well as in patients with microalbuminuria, may support the idea that the RFR capacity is more sensitive than microalbuminuria in assessing the early phase of diabetic nephropathy.     

The interaction of the diltiazem with oral and intravenous cyclosporine in rats.

This study investigated the effect of diltiazem on the bioavailability of oral and intravenous cyclosporine (CsA) in rats. While control rats received normal saline, experimental groups received 60 or 90 mg/kg diltiazem orally for 3 days. Each group divided into 2 equal groups that received a single oral dose or i.v. injection of CsA. Pharmacokinetic parameters were analyzed by nonparametric analysis of variance. Pretreatment with 60 or 90 mg/kg diltiazem decreased the area under the blood CsA concentration-time curve (AUC) of oral CsA compared to control group (54.5% and 65.5% for AUC(0-24), 57.6% and 62.2% for AUC(0-infinity), respectively, p<0.05). Mean CsA maximum concentration (Cmax) decreased from 0.4 +/- 0.1 microg/ml to 0.1 +/- 0.0 microg/mL in rats pretreated with 90 mg/kg diltiazem (p<0.05). The absolute bioavailability after oral administration (F(p.o.)) in the 60 or 90 mg/kg diltiazem groups were lower than the control group (9.6% and 8.5% versus 22.6%). Pretreatment with 90 mg/kg but not 60 mg/kg of diltiazem increased the AUC(0-infinity), elimination half-life (t1/2) of intravenous CsA (116.0%, 219.2%, respectively, p<0.05) and decreased the intravenous CsA clearence (CL(i.v.)) (62.9%, p<0.05). Diltiazem decreased the bioavailability of oral CsA, while it increased the bioavailability of intravenous CsA. One must consider this interaction when administering oral or intravenous CsA concomitantly with diltiazem.     

Protective effects of thymoquinone and methotrexate on the renal injury in collagen-induced arthritis

The goal of this investigation was to study the protective effects of thymoquinone (TQ) and methotrexate (MTX) on collagen-induced arthritis (CIA) in rats. On day 0 under ether anesthesia, the experimental groups were immunized with 0.5 mg native chick collagen II (CII) solubilized in 0.1 M acetic acid and emulsified in Freund's incomplete adjuvant. Control rats were gavaged with vehicle, whereas CII was administered intradermally. In addition, arthritis treated with TQ group received TQ (10 mg kg(-1) bw by gavage once a week for 3 weeks starting on day 0); and arthritis treated with MTX group received MTX (MTX was suspended in corn oil and administered by gavage at 1 mg kg (-1) bw once a week for 3 weeks starting on day 0). A significant decrease in the incidence and severity of arthritis by clinical and radiographic assessments was found in recipients of therapy, compared with that of controls. The MTX treatment significantly (P<0.01) decreased the elevated serum NO, urea and creatinine in arthritic rats. Likewise, TQ treatment was also able to reduce significantly (P<0.05) serum NO, urea and creatinine levels, but to lesser extent than MTX. The histopathologic abnormalities are consistent with the hydropic epithelial cell degenerations and moderate tubular dilatation in the some proximal and distal tubules. The severity of the degenerative changes in most of the shrunken glomerules and vascular congestion were also observed in arthritic animals. Preventive treatment of TQ and especially MTX significantly inhibited kidney dysfunction and this histopathologic alterations. These studies indicate that TQ can be used similar to MTX as a safe and effective therapy for CIA and may be useful in the treatment of rheumatoid arthritis.     

Effect of latanoprost/timolol and dorzolamide/tiomolol on intraocular pressure after phacoemulsification surgery

AIM: To evalaute the effect of fixed-combination latanoprost 0.005%/timolol maleate 0.5% and dorzolamide hydrochloride 2%/timolol maleate 0.5% on postoperative intraocular pressure after phacoemulsification cataract surgery. METHODS: This study is a prospective, randomized, double-masked and placebo-controlled. The study included 90 eyes of 90 patients which were scheduled to have phacoemulsification surgery. Patients were randomly assigned preoperatively to 1 of 3 groups (30 eyes of 30 patients). Two hour before surgery, the patients received one drop latanoprost/timolol (group 1), dorzolamide/timolol (group 2) and placebo (group 3, control group). The IOPs were measured at preoperative and postoperative 4, 8, and 24 hours. RESULTS: The preoperative mean intraocular pressure was not statistically significant between both drug groups and control group. In group 1 and 2, the postoperative mean IOP [group1: (14.03±3.15)mmHg and group 2: (14.16±4.43)mmHg] at 24 hours were significantly lower than the control group [(16.93±3.70)mmHg, (P<0.05)]. In addition, the postoperative mean IOP of group 1 [(14.90±3.69)mmHg] at 8 hours was significantly lower than the control group [(17.70±3.89)mmHg, (P<0.05)], but there was no significant difference between group 2 [(16.16±5.23)mmHg] and control group at 8 hours (P>0.05). CONCLUSION: When compared with placebo, the use of preoperative fixed combination of latanoprost/ timolol and dorzolamide/timolol is an effective method for preventing intraocular pressure elevation in 24 hours after phacoemulsification surgery, but did not completely prevent IOP spikes.     

Effect of honey on intestinal morphology, intraabdominal adhesions and anastomotic healing

In the present study, attempts have been made to determine the effects of honey on intestinal morphology, postoperative adhesions, and the healing of colonic anastomoses in the rats after colonic resection and anastomosis. Thirty-six rats were randomly divided into three groups each including 12 animals. Colonic resection and anastomosis were performed on all animals. Rats were fed with standard rat chow in group I, standard rat chow plus 10 g/kg/day honey in group II and artificial honey including the same caloric amount with honey in group III. Adhesion scores, bursting pressures and histopathological examinations were evaluated. Colonic bursting pressures of honey group were significantly better than control and artificial honey groups. Histological analysis of anastomotic site showed that submucosa and muscularis propria were nearly filled with granulation tissue and regular fibrin matrix in honey group. There was statistically significant difference between the adhesion scores of honey vs artificial honey and control groups. The scores of histological changes of ileum in honey group were significantly different from other groups. These results indicate a protective role of honey against intraabdominal adhesions and anastomotic dehiscence.     

Sexual dysfunction in patients with chronic hand eczema in the Turkish population

IntroductionHand eczema can cause considerable psychosocial disorders, such as anxiety, depression, and difficulties at work, and it may also cause sexual dysfunction.AimThe aim of this study was to investigate sexual function in patients with hand eczema and to find out whether concomitant depression has an additional negative effect on sexual function in these patients.Main Outcome MeasuresSexual functions were evaluated in hand eczema patients.MethodsNinety-one female (43 patients vs. 48 controls) and 79 male (45 patients vs. 34 controls) subjects were enrolled in the study. Hand eczema severity index was used to determine severity of hand eczema. The Female Sexual Function Index (FSFI) and the International Index of Erectile Function (IIEF) were used to assess sexual function. Quality of life was assessed with the Dermatology Life Quality Index. Diagnosis of depression was made based on the Structured Clinical Interview for the DSM-IV, while the Hamilton Depression Rate Scale was used for grading depression.ResultsAmong 43 female subjects with hand eczema, 26 had depression (60.46%); of the 45 male patients, 11 had depression (24.44%). FSFI total score was found to be significantly decreased in female patients with both eczema and depression compared with controls (20.84 ± 9.19 vs. 24.04 ± 3.40, P < 0.05). FSFI total score was found to be significantly decreased in female patients with both eczema and depression compared with those without depression (20.84 ± 9.19 vs. 22.23 ± 5.82, P < 0.05). IIEF total score was also found to be significantly decreased in male patients with or without depression compared with controls (52.36 ± 14.83 vs. 59.88 ± 5.65 vs. 62.03 ± 11.04, P < 0.05).ConclusionsThe results of the study demonstrated that patients with hand eczema had sexual dysfunction, and concomitant depression had an additional negative effect on sexual dysfunction. Patients with hand eczema should be evaluated with regard to sexual function and depression to provide a better quality of life.
