PURPOSE: We aimed to evaluate the efficacy of using testicular biopsy histopathology as an indicator of the success of loupe-assisted subinguinal varicocelectomy in non-obstructive azoospermia (NOA) patients. MATERIALS AND METHODS: In a 2-year period, a prospective study was carried at Minoufiya University Hospital on 20 NOA patients with clinical bilateral varicoceles. These patients underwent loupe-assisted subinguinal varicocelectomy with simultaneous testicular biopsy. All patients were evaluated by determining their hormonal profile and performing semen analyses and scrotal Doppler and transrectal ultrasonography. Two semen analyses showing azoospermia were performed before the surgery and two semen analyses were received at 3 and 6 months post-operatively for follow-up. RESULTS: The mean age was 29.9+/-6.7 years, and the mean follow-up duration was 17.3+/-8.3 months. We noted the restoration of spermatogenesis in six men (30% of all patients). Testicular biopsy results were as follows: hypospermatogenesis in 7 patients, maturation arrest in 3, and Sertoli cell-only syndrome in 10. The improvement in the sperm counts of these patients ranged from 3 million to 15 million/mL. Sperms were recovered in the hypospermatogenesis (6 patients, 85.5%) patients only, but other patients with testicular biopsy results of Sertoli cell-only or maturation arrest did not show any improvement in their semen parameters. CONCLUSIONS: Testicular biopsy results showed that hypospermatogenesis patients have a better chance of improvement in their semen analysis after varicocelectomy in contrast to NOA patients with Sertoli cell-only syndrome or maturation arrest.

There have been reports of the coexistence of abdominal aortic aneurysm (AAA) with intra-abdominal malignancy including gastric, colonic, pancreatic, and renal. We herein report a case of a previously undiagnosed AAA and a presenting complaint consistent with acute cholecystitis. Following cholecystectomy, this was noted to be a rare form of chronic cholecystitis: xanthogranulomatous cholecystitis. There is a known possible association of this uncommon condition with gallbladder cancer. The management of concomitant pathologies can present a real challenge to the multidisciplinary team, especially with large aneurysms.

BACKGROUND AND OBJECTIVES: Alzheimer's disease (AD) is a devastating neurodegenerative disorder. Increasing evidence implicates diabetes mellitus (DM) as a risk factor for AD. Green tea (GT) has several beneficial effects attributed to its anti-oxidant phenolic compounds. Adipose tissue is a rich source of adipose-derived mesenchymal stem cells (ADSCs). This study was designed to evaluate and compare the possible therapeutic effect of green tea extract (GTE) and ADSCs on AD complicating induced DM in male rat. METHODS: 31 adult male albino rats were divided into 5 groups. Group I (Control), Group II received GTE, 50 mg/kg daily orally for 4 weeks, Group III received a single intraperitoneal injection of Streptozotocin (STZ), 50 mg/kg, Group IV: received STZ followed by GTE and Group V: received STZ followed by human ADSCs (hADSCs) intravenously. RESULTS: Multiple acidophilic masses, deformed neurons, Congo red +ve masses and Caspase 3 +ve neurons were seen in group III, became few in group IV and occasional in group V. Multiple Prussian blue +ve cells were detected in group V. Some CD44 +ve cells were noticed in group III, became multiple in groups IV and V. The mean area of neurons exhibiting acidophilic cytoplasm, mean area of amyloid plaques and mean area % of Caspase 3 +ve cells indicated a significant increase in group III. The mean area % of CD44 +ve cells recorded a significant increase in group IV. CONCLUSIONS: hADSCs exerted a more marked therapeutic effect on the neurodegenerative changes complicating DM and corresponding to AD.
