Background. Endothelial damage and dysfunction are commonplace in renal transplant recipients. Impaired endothelial function is an important contributor to cardiovascular diseases. We hypothesized that short-term black tea consumption may improve endothelium-dependent arterial dilation in kidney recipients. Methods. Fifteen recipients were studied on an outpatient basis in a single, universityaffiliated clinic. Inclusion criteria were stable and good allograft function. The main exclusion criteria were uncontrolled hypertension, smoking, alcohol consumption, coffee drinking, diabetes mellitus, and coronary artery disease, or a history of upper limb vascular manipulations. After overnight fasting, the brachial artery diameter (BAD) was measured at the end of diastole using an ultrasound machine before (basal BAD) and 1 minute after temporary (3 minutes) external occlusion (posthyperemia BAD). Flow-mediated vasodilation (FMV) and percent of FMV (FMV%) were calculated by appropriate formula. FMV and FMV% were determined at baseline and 2 hours after consuming 0.5 L freshly brewed black tea. For control, the study was repeated for each patient the next day and FMV and FMV% were determined before and 2 hours after consuming 0.5 L of water. Results. The men age of patients was 37.2 9.7 years (range, 25 to 50) with a male:female ratio of 3:2. Patients were 26.8 10.6 months postrenal transplantation. Black tea consumption significantly increased posthyperemia BAD, FMV, and FMV% (P .05). However, water consumption did not alter the basal or posthyperemia BAD, FMV, or FMV% (P .05). Conclusion. Based on our study, short-term consumption of black tea may improve endothelial function and endothelium-dependent arterial vasodilation in renal transplant recipients.

Patients on maintenance hemodialysis (HD) face an increased risk of atherosclerosis, a crucial problem and the leading cause of cardiovascular morbidity and mortality. This study was designed to evaluate the effects of zinc supplementation on paraoxonase (PON) enzyme activity in patients on HD.This double-blind randomized controlled trial was conducted from June 2005 to June 2007. Sixty HD patients were enrolled and divided into two groups: treatment (case) and control. The treatment and control groups were treated with 100 mg/day zinc or placebo, respectively, for 2 months. Serum zinc concentration was measured by atomic absorption spectrophotometry. PON activity was evaluated by spectrophotometric method. Lipid profile was determined using commercial kits, and apolipoprotein AI (Apo-AI) and B (Apo-B) levels were measured by commercial immunoturbidimetric kits.In the case group, there was no significant change in the serum total cholesterol (TC), triglyceride (TG), low-density lipoprotein (LDL), and Apo-B levels, while the serum levels of high-density lipoprotein (HDL), Apo-AI, and PON activity were significantly increased (p = 0.02). In the control group, although significant increases were observed in the serum levels of TC, TG, and Apo-B (p = 0.009, 0.019, and 0.001, respectively), the serum PON activity was significantly decreased (p = 0.025) and the serum levels of HDL, LDL, and Apo-AI were not changed. At the end of intervention period, the serum level of Apo-AI and PON activity were significantly higher in the case group.Zinc supplementation increased both the activity of PON and the serum level of Apo-AI in the HD patients.

Retinal arteriovenous malformations are rare and most are reported to be asymptomatic. We report an 11-year-old boy who attended for blunt trauma to his eye. The first ophthalmologic examination was performed in Nikookari Hospital Eye Emergency Room. Visual acuity was 20/20 and relative afferent pupillary defect was negative in both eyes. Ophthalmoscopic examination revealed multiple massive dilated retinal vessels in the superior arcade of the right eye. The arteriovenous malformation was not associated with exudation, hemorrhage or abnormal pigmentation. The left eye examination was unremarkable. We performed fluorescein angiography and brain magnetic resonance imaging (MRI). In the right eye fluorescein angiography, the malformation was not associated with leak or edema. The left eye fluorescein angiography was unremarkable. Brain MRI was unremarkable. After 16 months follow-up, there were no symptoms. This is the first case report from the Middle East region. To the best of our knowledge, retinal arteriovenous malformation has rarely been reported in children. Previously published literature suggests that these malformations may become complicated in time. Brain MRI is strongly recommended because of the possibility of Wyburn–Mason syndrome.

Purpose To investigate the effect of subconjunctival bevacizumab immediately after excision of primary pterygium. Methods Eighty patients (80 eyes) with primary pterygium were included in this double-blind clinical trial. The pterygia were excised by the bare sclera technique. Then, the patients were randomized in 2 equal groups; group A received subconjunctival bevacizumab (1.25 mg/0.1 mL) injected immediately after surgical excision of the pterygium, and placebo was administered in the same way in group B. Patients were followed-up for 9 months after the operation, and the possible complications and recurrence rate were documented. Thirty-three patients (33 eyes) completed the study in each group. Results The rate of complications was comparable between the 2 groups (57.6% in group A versus 63.6% in group B; P = 0.61). None of these complications was clinically significant, and they resolved spontaneously or by using conservative measures. The recurrence rate was higher in group B compared with group A (57.6% vs. 45.5%); however, this difference was not statistically significant (P = 0.33; odds ratio, 1.63; 95% confidence interval, 0.62-4.31). Conclusions Subconjunctival injection of bevacizumab immediately after surgical excision of primary pterygium is well-tolerated, but it cannot significantly prevent the recurrence of this condition.

A supernumerary renal artery is a common arterial variation, which warrants considerations in a variety of urologic and retroperitoneal operations. Supernumerary renal arteries can be associated with other uro-vascular variations and anomalies such as duplicated renal veins and ureters, aberrant origin of the gonadal arteries, persistence of fetal renal lobulation, and kidney malrotation. The role of crossing supernumerary renal arteries in ureteropelvic junction obstruction (UPJO) is controversial. We report a healthy potential renal transplant donor with bilateral UPJO, which appeared to be secondary to supernumerary renal (inferior polar) arteries. We believe that the bilateral occurrence of asymptomatic UPJO associated with supernumerary renal arteries has not been previously reported.

Celiac artery aneurysm (CAA) is a rare condition, which occasionally occurs in association with such visceral aneurysms as splenic, common hepatic, left hepatic, superior mesenteric and renal arteries. We describe our observation of a patient with CAA and bilateral main renal artery aneurysm. To the best of our knowledge, a combination of these visceral arterial aneurysms has not been reported previously. The available literature on this topic is briefly reviewed.

To determine the susceptibility of low-density lipoprotein (LDL) to oxidation in the plasma of male patients with wet type age related macular degeneration (AMD) and in a similar control group, in order to evaluate the LDL oxidative status as risk factor of AMD.We conducted this study in the Retina Service, Department of Ophthalmology, Nikookari Eye Hospital-Drug of Applied Research Center, Tabriz University of Medical Sciences, Tabriz, Iran during the period between October 2004 and December 2005. Sixty male patients with AMD (mean age 67 +/- 16 years) with BMI 4.1 +/- 1.3 were selected as the patient group. The control group consisted of 60 males, apparently healthy, and without ophthalmologic signs and family history of AMD. Low-density lipoprotein was isolated by gradient ultracentrifugation and susceptibility of LDL to in vitro copper-mediated oxidation was assayed by measuring conjugated dienes production (lag phase duration) at 234 nm. Lipid and lipoproteins were determined by standard methods.Comparing with control, significant reduction in the duration of lag phase (p0.004) and a significant increase in LDL-C concentrations (p=0.006), were noticed. No significant change in cholesterol (p0.3), triglyceride (p0.1) and high density lipoprotein cholesterol (p0.1) levels were found between control and patient groups. A significant negative correlation between Lag phase and LDL-C levels (p=0.004, r=-0.364) was found in the patient group.The increased LDL concentration and enhanced susceptibility of LDL to oxidation may play a roll in the wet type AMD process.

Background Finasteride is a competitive inhibitor of 5 alpha-reductase enzyme, and is used for treatment of benign prostatic hyperplasia and androgenetic alopecia. Animal studies have shown that finasteride might induce behavioral changes. Additionally, some cases of finasteride-induced depression have been reported in humans. The purpose of this study was to examine whether depressive symptoms or anxiety might be induced by finasteride administration. Methods One hundred and twenty eight men with androgenetic alopecia, who were prescribed finasteride (1 mg/day) were enrolled in this study. Information on depressed mood and anxiety was obtained by Beck Depression Inventory (BDI), and Hospital Anxiety and Depression Scale (HADS). Participants completed BDI and HADS questionnaires before beginning the treatment and also two months after it. Results Mean age of the subjects was 25.8(± 4.4) years. At baseline, mean BDI and HADS depression scores were 12.11(± 7.50) and 4.04(± 2.51), respectively. Finasteride treatment increased both BDI (p < 0.001) and HADS depression scores significantly (p = 0.005). HADS anxiety scores were increased, but the difference was not significant (p = 0.061). Conclusion This preliminary study suggests that finasteride might induce depressive symptoms; therefore this medication should be prescribed cautiously for patients with high risk of depression. It seems that further studies would be necessary to determine behavioral effects of this medication in higher doses and in more susceptible patients.
