Emphysematous pyelonephritis in a transplant kidney

Emphysematous pyelonephritis [EPN] is a severe necrotizing infection of the kidney and its surrounding tis- sues. It is characterized by the production of gas within the kidney and perinephric structures. EPN often affects diabetic women but can also occur in nondiabetic patients who have ureteral obstruction and in im- munocompromised patients. Herein, we report EPN in a 23-year-old woman who had a renal transplantation

Chrysomya bezziana as a causative agent of human myiasis in Fars Province, Southern Iran

Myiasis is the invasion of body tissues of humans or animals by the larvae of the Diptera or two-winged flies. The various forms of myiasis may be classified from clinical or entomological point. This study describes the existence of Chrysomya bezziana [Diptera: Calliphoridae] cases as a causative agent of myiasis in 18 and 87 year-old men in two different regions in Fars Province. To our knowledge, this is the first observation of mentioned species in this province

nutcracker syndrome: an underdiagnosed cause for high grade varicocele

The nutcracker syndrome represents a clinical condition caused by compression of the left renal vein [LRV] between the superior mesenteric artery [SMA] and the aorta. One of its manifestations is left-sided varicocele. The aim of this study is to determine the prevalence of nutcracker syndrome in patients with primary and recurrent high grade left-sided varicocele. Fifty patients with primary and recurrent high grade left-sided varicocele were enrolled in this study. Color Doppler ultra-sonography [US] of renal vessels was done and diameter of LRV and peak systolic velocity [PSV] were measured in renal hilum and in site of compression of LRV be-tween SMA and the aorta and then magnetic resonance angiography [MRA] of renal vessels was done. Thirty six patients [72%] had primary high grade varicocele and 14 patients [28%] had recurrent high grade varicocele. Twelve patients [33%] with primary high grade varicocele and seven patients [50%] with recurrent varicocele had evidences of NCS in color Doppler US and MRA. The differences of LRV diameter in NCS group and in patients without NCS were statistically significant [P<0.001]. The differences of PSV in the LRV at the hilar portion in the NCS group and in the patients without NCS were not statistically significant. The differences of PSV in the LRV at the aortomesenteric portion in the NCS group and in the patients without NCS were statistically significant [P< 0.001]. In all patients with NCS, MRA showed dilatation and compression of LRV at site of passage between aorta and SMA. NCS should be suspected in patients with high grade primary and recurrent varicocele

incidence of diverticula of urinary bladder in patients with benign prostatic hypertrophy and the comparison between cystoscopy and cystography in detecting bladder diverticula

The majorities of bladder diverticula are acquired and are secondary to either bladder outlet obstruction or the upper motor type of neurogenic bladder. This study was undertaken to increase awareness and understanding the putative role of BPH [Benign Prostatic Hyperplasia] in the development of bladder diverticula and to compare cystoscopy and cystography in detecting bladder diverticula. During a 4-month period, 106 patients with BPH, who were admitted in the hospital for surgery, were examined by cystoscopy to detect bladder diverticula. Thirty-one patients were selected randomly and underwent cystography. In this study, the rate of bladder diverticula in patients with BPH was 27.4% by cystoscopy while by cystography, it was 48%.There was a slight increase of bladder diverticula with increasing age. This research also depicted that the detection rate of diverticula cystography in of urinary bladder was much greater than that of cystoscopy. This study shows that the prevalence of bladder diverticula is considerably high. The detection rate of cystography in diverticula of urinary bladder was much greater than that of cystoscopy. Considering this high prevalence and potential complications, we suggest cystography for the early diagnosis and possible treatment of bladder diverticula in older patients with lower urinary tract symptoms
