摘要:

Propofol (Diprivan) in a new formulation, a short-acting intravenous anesthetic, was used as an induction agent for short urological procedures. Forty unpremedicated patients were treated with either propofol or thiopental in a randomized study. The onset of anesthesia and duration of apneic period were prolonged and the decrease in systolic blood pressure was more profound in the propofol group. Heart rate was less stable and recovery time was longer in the thiopental group. Other parameters, such as quality of anesthesia, acceptability of the drug or rate of side effects, were similar in both groups. These results suggest that propofol in a new formulation is a suitable agent for short urological procedures in outpatient surgery.

摘要:

Structural chromosomal aberrations, such as translocations or inversions, may cause spermatogenic failure. We report a rare chromosomal anomaly 46, X, t(Y;3)(q12;p21) in an azoospermic male with normal phenotype. Twenty-two cases of a balanced Y-autosome translocation have been reported in the literature and the majority of them have been detected among azoospermic males at male infertility clinics. This structural chromosomal anomaly brings spermatogenic arrest at the primary or secondary spermatocyte.

摘要:

Polyorchidism is an unusual abnormality of the genital tract in which supernumerary testicles are present, usually within the scrotum. We report a recently encountered case with no remarkable symptoms. Preoperative ultrasonographic evaluation differentiates this rare benign entity from more ominous abnormalities such as neoplastic involvement of the scrotal contents.

摘要:

We describe a case of adrenal myelolipoma that simulated clinically and biochemically a virilizing adrenal tumor. The tumor was removed surgically. The preoperative diagnosis of adrenal myelolipoma can be made by the characteristic appearance on ultrasonography, computerized tomography and in equivocal cases by guided needle biopsy.

摘要:

We report a case of secondary penile carcinoma with primary tumor in the pancreas. Immunoperoxidase tissue staining of carbohydrate antigen 19–9, carcinoembryonic antigen and prostate-specific antigen was useful for diagnosis of original tumor.

摘要:

A case of pheochromocytoma presenting as an acute abdominal emergency with shock is described. Shock was followed by transient hypertensive crisis and thereafter by spontaneous remission of clinical symptoms. The surgically removed tumor showed extensive necrosis.
