cryptorchidism/吐き気

Previous epidemiological studies of cryptorchidism have led to the hypothesis that the risk of undescended testis is associated with excess oestrogen exposure during pregnancy. A case-control study was undertaken to test this hypothesis, comparing mothers of affected boys (244) and normal male

The hypothesis that undescended testis is caused by an excess of maternal oestrogen in pregnancy has been tested indirectly in a case-control study comparing mothers of boys with undescended testis (83) and mothers of normal boys (129) born on the same day. The study concentrated on the gestation of

We sent questionnaires to 424 retina specialists in order to compile information on the use of fluorescein angiography in pregnant women. Four-hundred and three specialists responded. Of these, 313 (78%) had never performed fluorescein angiography on a pregnant woman. Ninety specialists (22%) had

Intraoperative analgesia was performed using a combination of tramal at a dose of 2-2.5 mg/kg and transcranial electrical stimulation under halothane-nitrous oxide-oxygen mask anesthesia. The study was performed in 12 apparently healthy boys aged 11-13 operated on for II to III degree varicocele.

Germ-cell testicular cancer has a well-characterized descriptive epidemiology, whereas the aetiology remains largely unknown. It is believed that exposures acting prenatally are instrumental to germ-cell cancer development, although no specific exposure has been identified. Several epidemiological

Undescended testicle is the most common congenital anomaly among males. Testicular tumor develops in 3-5% of the boys with a complaint of undescended testicle. The clinical presentation of malignant intra-abdominal testicular tumors ranges from asymptomatic cases to acute abdomen. In this study, we

Persistent Mullerian duct syndrome is a rare entity and usually presents with common symptoms of undescended testis and hernia. The syndrome is caused by an insufficient amount of Mullerian inhibiting substance or due to the insensitivity of the target organ to Mullerian inhibiting substance.

An individual matched case-control study of testis cancer in 131 men under age 40 was conducted to investigate antecedent risk factors including events during prenatal life. Ten patients were born with an undescended testis compared to only two controls (p less equal to 0.02), a previously reported

BACKGROUND Torsion of an intraabdominal testicular tumor is a rare event. We report a new case and review the literature. METHODS A review of the literature was carried out in order to identify reported cases of an intraabdominal testicular tumor undergoing torsion of its vascular pedicle. Data on

In this case--control study of 108 cases of testicular cancer in men under 30 years of age, cryptorchidism was a major risk factor [relative risk (RR) = 9.0]. Low birth weight was also associated with increased risk (RR = 3.2). Having severe acne at puberty was protective (RR = 0.37). Interviews

We sent 424 retina specialists questionnaires on fluorescein angiography performed on pregnant women; 399 specialists responded. Of these, 309 (77%) had never performed fluorescein angiography on a pregnant woman. Ninety specialists (23%) had performed at least one fluorescein angiogram on a

BACKGROUND Therapies containing two reverse transcriptase inhibitors (RTI) with or without protease inhibitors are used with increasing frequency in pregnant HIV-infected women. OBJECTIVE To assess the safety of antiretroviral therapy in pregnant women and their newborns. METHODS All clinical events
