Sensitivity and specificity of ultrasonography in predicting etiology of azoospermia.

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 transrectal US examinations, were performed in all patients and compared with the testicular biopsy results as the reference standard.

Systemic lupus erythematosus after thymectomy for myasthenia gravis: a case report and review of the literature.

Here, we report a case of systemic lupus erythematosus in a 13-year-old girl who developed the disease 3 years after thymectomy performed for the treatment of myasthenia gravis. The presenting symptoms were fever, generalized fatigability, bilateral loin pain, weight loss, arthralgia, hair loss, and recurrent painless mouth ulcers. Laboratory findings revealed proteinuria, hematuria, anemia, leucopenia, a high titer of antinuclear antibodies (ANA), anti-dsDNA, and decreased complement (C3 and C4) levels.

Calciphylaxis cutis: a case report and review of literature.

Calciphylaxis is a poorly understood syndrome of vascular calcification and skin necrosis. It affects 1-4% of the population with end stage renal disease (ESRD). Disorders implicated in the pathogenesis of calciphylaxis include chronic renal failure, hypercalcemia, hyperphosphatemia, an elevated calcium-phosphate product, and secondary hyperparathyroidism (Essary, L.

Decidual immune cell infiltrate in hydatidiform mole.

Background: Hydatidiform mole is a gestational trophoblastic disease characterized by proliferation of the pregnancy-associated trophoblastic tissue. Complete hydatidiform mole is an entirely paternally derived lesion, and therefore, represents complete intrauterine allografts that can induce an altered maternal immune response Hypothesis: Here, we hypothesize that "the development of hydatidiform moles is associated with numeric alterations of the decidual immune cell infiltrate."

Materials And Methods: A total of 30 specimens (decidual tissue), entailing normal first trimester pregnancy terminations and complete hydatidiform moles (15 cases, each), were evaluated for immune cell infiltrate using immunohistological methods and monoclonal antibodies (CD20, CD68, and CD3 for B cells, histiocytes/dendritic cells, and T cells, respectively).

Melatonin and roentgen irradiation-induced acute radiation enteritis in Albino rats: an animal model.

Background: Roentgen irradiation can affect normal cells, especially the rapidly growing ones such as the mucosal epithelial cells of the small intestine. The small intestine is the most radiosensitive gastrointestinal organ and patients receiving radiotherapy directed to the abdomen or pelvis may develop radiation enteritis. Although roentgen rays are widely used for both imaging and therapeutic purposes, our knowledge about the morphological changes associated with radiation enteritis is lacking.
