Endometrial carcinoma presenting as hematometra mimicking a large pelvic cyst.

Large pelvic cysts are commonly seen in gynecologic practice; their heterogeneous origin is reflected in their pleomorphic clinical features. We report the case of a 64-year-old multiparous postmenopausal woman with an unusual manifestation of endometrial adenocarcinoma that presented as hematometra mimicking a large pelvic cyst. In this case, hematometra was well demonstrated by transabdominal sonography, but transvaginal sonography allowed better visualization of the endometrial lining and suggested the correct diagnosis of endometrial cancer. Abnormal vaginal bleeding or hematometra in postmenopausal women should lead to assessment of the endometrial mucosa. Transvaginal sonography can be used to visualize neoplastic lesions in the endometrium when hematometra is detected through transabdominal sonography.

The success of closed reduction in the treatment of complex developmental dislocation of the hip.

The purpose of our study was to determine the efficacy of closed reduction in the treatment of complex developmental dislocation of the hip. We identified two factors, the cone of stability and the limbus type, through the use of arthrography and gentle examination under anesthesia, which are useful guidelines in the management of complex developmental dislocation of the hip. We feel as a result of this study we can select those cases of complex developmental dislocation of the hip that are amenable to closed reduction and separate them from those other cases for which we recommend open reduction.

Cranial and orbital growth in Chinese fetuses.

We assess Chinese fetal orbital growth by biparietal diameter (BPD) in normal pregnancies. One hundred and ninety-six normal fetuses, whose gestational periods ranged from 14 weeks to term, were measured by prenatal ultrasonography. Orbital parameters measured included orbital diameter (OD), biorbital distance (BOD), and interorbital distance (IOD). At the same time, fetal BPD was measured. The results show that orbital growth correlates well with BPD; OD versus BPD (r = 0.94, p less than 0.001), BOD versus BPD (r = 0.96, p less than 0.001), and IOD versus BPD (r = 0.83, p less than 0.001). Polynomial regression analysis demonstrates that the best-fit model for orbital parameters versus BPD was the first-order linear regression. From the above analysis, the 5th, 50th and 95th confidence limits of OD, BOD, and IOD were computed for specific growth values of BPD, and these can serve as a reference for prenatal diagnosis of fetal orbital malformations when menstrual age is not defined.
