BACKGROUND Angina without significant stenosis, or nonobstructive coronary artery disease, attracts clinical attention. Microvascular coronary artery spasm (microvascular CAS) can cause nonobstructive coronary artery disease. We investigated the clinical features of microvascular CAS and the therapeutic efficacy of calcium channel blockers. METHODS AND RESULTS Three hundred seventy consecutiv...
BACKGROUND Despite a nonobstructive coronary angiogram, many patients may still have an abnormal coronary vasomotor response to provocation and to myocardial demand during stress. The ability of noninvasive stress tests to predict coronary vasomotor dysfunction in patients with nonobstructive coronary artery disease is unknown. METHODS AND RESULTS All patients with nonobstructive coronary art...
OBJECTIVE To determine the sensitivity and specificity of different ultrasound (US) modalities in predicting an obstructive vs a nonobstructive etiology of azoospermia. MATERIALS AND METHODS A total of 268 azoospermic men with available histopathologic slides were separated into obstructive (n = 104) and nonobstructive (n = 164) groups. Scrotal US studies, including color Doppler and transrec...
Nonobstructive azoospermia (NOA) is characterized by the complete absence of sperm in the ejaculate due to testicular failure. The evaluation and management of patients with NOA offer a challenge to the reproductive urologist. In the era of in vitro fertilization with intracytoplasmic sperm injection, surgical sperm extraction techniques can afford men with NOA biologic paternity. To provide a ...
Hepatoid adenocarcinoma (HAC) is the term proposed for a special type of extrahepatic tumors, which is similar to the hepatocellular carcinoma (HCC) both in the histopathology and immunohistochemistry. HAC has been observed in the stomach, colon, pancreas, gall bladder, lung and female genital tract, but rarely in the mediastinum. Now we describe a case of a 28-year-old Chinese male with primar...
PURPOSE Multiple small case series have reported sperm in the ejaculate and spontaneous pregnancies in patients with nonobstructive azoospermia after varicocele repair. We hypothesized that men with favorable testicular histopathology on testis biopsy such as maturation arrest or hypospermatogenesis would have a higher probability of success than those with more ablative pathology, eg Sertoli-c...
Introduction: Obstructive coronary artery disease (CAD) in proximal segments is associated with a poor prognosis. However, the contribution of plaque location to major adverse cardiovascular events (MACE) among patients nonobstructive CAD not well defined. We examined MACE risk relation non-obstructive by CT angiography (CCTA).
We report a 71-year-old man who had undergone pylorus-preserving pancreatoduodenectomy (PPPD) using PPPD-IV reconstruction for cholangiocarcinoma. For 6 years thereafter, he had suffered recurrent cholangitis, and also a right liver abscess (S5/8), which required percutaneous drainage at 9 years after PPPD. At 16 years after PPPD, he had been admitted to the other hospital because of acute puru...
Objective: To develop methods for the isolation and purification of round spermatids (RS) from ejaculated semen specimens recovered from patients suffering from nonobstructive azoospermia for the purpose of performing intracytoplasmic round spermatid injections (ROSI) into human oocytes. Design: Prospective study. Setting: Audrology Institute of Lexington, Lexington, Kentucky. Patients: Six men...
OBJECTIVES The goal of this study was to determine the long-term prognostic value of coronary computed tomography angiography (CTA) among patients with diabetes mellitus (DM) compared with nondiabetic subjects. BACKGROUND The long-term prognostic value of coronary CTA in patients with DM is not well established. METHODS Patients enrolled in the CONFIRM (Coronary CT Angiography Evaluation fo...
