Background
In most case control studies the hardest decision is the choice of the control group, as in the ideal control group the proportion exposed is the same as in the population that produced the cases. 相似文献123.

We describe laparoscopic diagnosis and treatment for a case of dysgenetic
male pseudohermaphroditism with persistent Mullerian ducts. The patient, a
32 year old man, with a history of surgery for hypospadias and
cryptorchidism during childhood, was referred because of anejaculation. He
was of short stature, with male external genitalia composed of a small
penis and hypoplastic testis (1 ml right, 6 ml left side). Plasma follicle
stimulating hormone (FSH) was high (17 mUI/ml), testosterone low (1.9
ng/ml), and his karyotype was 46,XY. Pelvic ultrasound, nuclear magnetic
resonance (NMR) and genitography disclosed a uterine-like structure with
cavity communicating with the urethra. Laparoscopy and urethrocystoscopy
confirmed the presence of a 4 cm uterus, which was removed endoscopically
at the same time. A biopsy of the left gonad was also performed. The uterus
contained endometrial tissue and was fibrotic. Histology of the left gonad
showed spermatocytic arrest. We diagnosed dysgenetic male
pseudohermaphroditism. Laparoscopy, in our opinion, is an optimal tool to
diagnose and treat abnormal sexual conditions.

In order to detect left ventricular (LV) thrombosis, 111In-platelet scintigraphy and two-dimensional echocardiography were performed in 40 patients 15 days±6 days after acute myocardial infarction. A dual isotope subtraction method, using 111In-platelet scintigraphy and 99mTc-blood pool scintigraphy, was used to assess LV platelet deposition expressed as LV counts per pixed. Seven patients (group A) had a positive 111In-platelet scintigram and 33 patients (group B) had a negative 111In-platelet scintigram (LV counts per pixel: 0.56±0.23 and 0.28±0.19, respectively, P<0.05). Three group A patients but no group B patients had a positive echocardiogram. Arterial embolism was noted in four patients, of whom two showed both positive echocardiogram and platelet scintigram. LV counts per pixel were 0.57±0.13 and 0.31±0.21, respectively (P<0.02) in patients with and without arterial embolism. Thus, both 111In-platelet scintigraphy and two-dimensional echocardiography can detect LV thrombosis. 111In-platelet scintigraphy may help to define patients at risk for embolization and may be used in conjunction with echocardiography to study the effect of antithrombotic therapy. 相似文献

Aim: To compare the 5‐year survival without major disability in infants born at the threshold of viability at 22–25 weeks who were actively treated in the delivery room and admitted to a NICU to that of those born at 26–27 weeks of gestation. Methods: All infants between 22+0 and 27+6 weeks of gestation admitted to a regional intensive care unit during 1999–2003 were enroled prospectively. The survival and major disability at 5 years of age were analysed by gestational age. Results: Of 242 treated infants, 202 survived (83.5%). Although the overall survival rate was significantly higher in the 25–27 weeks’ gestation infants than the 22–24 weeks’ gestation infants (p < 0.001), the survival rate among infants 22–24 weeks (63.6%, 63.6%, and 70%) did not significantly differ, likewise infants 25–27 weeks (88.7%, 90.6%, and 92%) had similar results. Overall, 28 children (14.4% of assessed) had major disability. Both survival and survival without major disability were positively influenced by increasing gestational age, increasing birth weight, being born at 25–27 weeks and being female child. Conclusion: With an active approach in treatment, the outcome of infants born at 25 weeks is comparable to those born at 26–27 weeks. Thus, the ‘grey zone’ in which the risk of adverse outcome is high narrows to 22–24 weeks. 相似文献
