Percutaneous epididymal sperm aspiration (PESA), percutaneous testicular sperm aspiration (TESA) and testicular sperm extraction (TESE) are invasive procedures and their consequences on the testis have not been clearly defined. In order to relate the sonographic and colour Doppler flow changes to the clinical data, 14 patients with non-obstructive and six with obstructive azoospermia were exami...
Lymphoepithelial cyst of oral cavity is a rare cystic lesion that presents as an asymptomatic submucosal mass and is usually discovered during routine dental examinations. The site most commonly affected is floor of the mouth and tonsillar involvement seems to be very rare. Multiple Lymphoepithelial cysts have been reported in parotid of HIV positive patients however in oral cavity they usua...
INTRODUCTION Chronic obstructive pulmonary disease in non-smokers has been an important concern in past decade. We studied the risk factors responsible for more severe Chronic obstructive pulmonary disease. Identifying them would help to work against progression to more severe disease as well as prevention. METHODS A prospective cross sectional study was done in outpatient clinic of Jinnah po...
Comparative Immunohistochemical Study of Multicystic Dysplastic Kidneys With and Without Obstruction
Etiology of multicystic dysplastic kidney (MCDK) remains unknown. Not all cases are associated with obstruction. We compared by immunohistochemistry 17 cases of MCDK (10 cases with and seven without obstruction) to 17 controls and 20 fetal kidneys. TGF-β was negative in obstructive MCDKs and positive in nonobstructive MCDK. IGF2 was overexpressed in obstructive and underexpressed in nonobstruct...
BACKGROUND Previous studies have demonstrated the relevance of left coronary artery dominance in the outcome and prognosis of obstructive coronary artery disease (CAD). However, no studies have investigated the influence of coronary vessel dominance on non obstructive CAD. The aim of this study was to establish the association of left and mixed dominance of the major epicardial arteries with th...
BACKGROUND Coronary computed tomography angiography (coronary CTA) can prognosticate outcomes in patients without modifiable risk factors over medium term follow-up. This ability was driven by major adverse cardiovascular events (MACE). OBJECTIVE Determine if coronary CTA could discriminate risk of mortality with longer term follow-up. In addition we sought to determine the long-term relation...
In this study we evaluated the incidence and severity of obstructive sleep apnea and Obstructive sleep apnea syndrome in patients with thromboangiitis obliterans for reduction of crisis. In 40 patients with Buerger's disease daily sleepiness and risk of Obstructive sleep apnea were evaluated using the Epworth sleeping scale (ESS) and the Stop-Bang score. An Apnea-link device was used for evalua...
Obstructive azoospermia is a common cause of male infertility and can result from infection, congenital anomalies, or iatrogenic injury. Microsurgical vasal reconstruction is a suitable treatment for many cases of obstructive azoospermia, although some couples will require sperm retrieval paired with in-vitro fertilization. The various causes of obstructive azoospermia and recommended treatment...
Various procedures for sperm recovery in azoospermic men have been described, from open testicular biopsy to simple needle aspiration from the epididymis and the testis. Fifty-one obstructive and 86 non-obstructive azoospermic men were treated to compare the recovery of spermatozoa obtained by percutaneous aspiration from the epididymis (PESA) and aspiration/extraction from the testis (TESA, TE...
