Detection of Chlamydia trachomatis antigen by enzyme immunoassay in patients with pelvic inflammatory disease.

In 27 out of the 60 women clinically suspected to have pelvic inflammatory disease (PID) studied, the C. trachomatis antigen titre was found to be higher than the cut-off value. Since the presence of C. trachomatis antigen was detected in 45 per cent of women, it is suggested that all the PID patients may be investigated by ELISA to confirm the role of C. trachomatis as the etiological agent.

Postcaesarean wound infection: a review of risk factors.

In a prospective study of 431 cases delivered by caesarean section, wound infection developed in 54 (12.52%) cases. In 2.55% cases, infection was deep with drainage of purulent material. The factors associated with a high risk of wound infection were anaemia, multiple pelvic examinations, prolonged rupture of membranes and handling by dai. General ward cases had a significantly higher wound infection rate than the private ward cases.

A special purpose x-ray fan-beam CT scanner for trabecular bone density measurement in the appendicular skeleton.

A special purpose x-ray CT scanner with the capability of scanning objects 75-220 mm in diameter with constant relative geometrical resolution has been developed. The data collection scheme for the scanner uses multiple rotations of a linearly shifted, asymmetric fan beam permitting user-defined variable resolution. Details of hardware and the calibration procedures for the scanner are described and the methods used to measure trabecular bone density (TBD) in the peripheral skeleton are outlined. The standard error of estimate (SEE) of a calibration line of pixel value as a function of K2HPO4 concentration was determined to be 0.07%. The short-term, in vivo precision of the TBD determination, by repeated measurements of a volunteer with repositioning between each measurement, was +/- 0.67% (coefficient of variation (CV] with a 50s scan time and a radiation dose of less than 20 mR per slice.

Placental pathology in pre-eclampsia eclampsia syndrome.

Quantitative analysis of placental pathology was carried out on 20 placentae from various grades of pre-eclampsia eclampsia syndrome and 20 placentae from control group. Placental weights were lower in the study group. The gross abnormalities noted were the placental infarcts, retroplacental haematoma and calcification. The striking villous lesions observed in the study group were cytotrophoblastic cell proliferation, thickening of villous basement membrane and paucity of vasculosyncytial membrane and these findings correlated well with the severity of maternal disease. These vascular villous lesions were considered secondary to uteroplacental ischaemia.
