UREAPLASMAS UREALYTICUM AND HUMAN INFERTILITY: EFFECT ON SPERMATOZOA MORPHOLOGY

Seminal fluids of 197 males with complaints of involuntary infertility were examined for spermatozoal counts, morphological changes in the spermatozoa and cultured for ureaplasmas and mycoplasmas. In 12, no spermatozoa were present, 29 had a count of less than one million and 156 had more than one million spermatozoa per mL of the seminal fluid. Various morphological changes were detected in the spermatozoa in some cases. U urealyticum and M hominis were grown in 43.15% and 16.75% in comparison to control figures of 15.9% and 11.4% respectively. There was no correlation between growth of ureaplasmas and the spermatozoal count. Among the morphological changes, presence of coiled tails, presence of a fuzzy coat around the tail and microcolonies were highly specific for culture positivity (98.2, 98.2 and 97.35% respectively) but of low sensitivity (55.2%, 14.1% and 8.2% respectively).KEY WORDS: Mycoplasma, Spermatozoa, Ureaplasma     

OVARIAN HYPERSTIMULATION SYNDROME DURING INDUCTION OF OVULATION FOR INTRA UTERINE INSEMINATION

Ovarian Hyperstimulation Syndrome (OHSS) is a known iatrogenic complication of ovulation induction. Our experience of such complication while managing basic assisted conception cycles has been analysed in the present study. 12 such cases were identified in 976 cycles studied giving an overall incidence of 1.22%. All the cases were of mild to moderate variety and were managed conservatively. The duration of the complication ranged between 10 days to 6 weeks. Polycystic ovarian disease, LH: FSH ratio of more than 1, presence of four or more secondary follicles were found to be important predictive criteria. Identification of predictive factors of OHSS can be helpful in taking due care while using ovulation inducing drugs. Conception does worsen OHSS, but termination is usually not necessary.Key Words: OHSS, Ovulation Induction     

TO STUDY INCIDENCE OF CHLAMYDIAL GENITAL TRACT INFECTIONS USING ENZYME IMMUNO ASSAY-ANTIGEN DETECTION AND CELL CULTURE METHODS

Endocervical swabs from 315 patients were screened for chlamydial infection by using Enzyme Immuno Assay technique for antigen detection. Of these, 190 patients were of infertility and 125 patients were with history suggestive of pelvic inflammatory disease (PID). 100 age matched controls were also screened for the detection of chlamydial antigen by using EIA. The overall incidence of chlamydial infection in this study group was 15.2%. 21 (11.05%) of the infertility patients and 27 (21.6%) of the pelvic inflammatory disease cases were found to be positive for chlamydial antigen. The prevalence rate was found to be high in the age group of 31–40 years in both study groups i.e. infertility group (14.7%) and PID group (50%). All the ELISA positive cases (48) and randomly selected (10) age matched controls were screened by tissue culture using McCoy cell line. In the tissue culture, 44 of the 48 samples were found to be positive and none of the controls groups were found positive. 4 samples showed discordant results possibly due to the presence of non-viable organism or inhibitory material present at the sample site. The sensitivity and specificity of ELISA with respect to tissue culture are 100% and 71% respectively. The positive predictive value and the negative predictive value of the ELISA are 91.6% and 100% respectively. The efficiency of the test was found to be 93.1%.Key Words: Chlamydia trachomatis, Infertility, PID     

术中胆道造影在腹腔镜胆囊切除术中发现胆道损伤的作用

目的：评估术中胆道造影（IOC）在早期发现腹腔镜胆囊切除术（LC）术中胆道损伤的作用。方法：回顾分析31例LC术后胆道损伤的部位，机理，诊断时间，治疗方法及结果，并对是否行IOC进行评估。结果：胆道错认引起胆道损伤共19例，其中12例IOC显示胆道错认，致胆道部分切开损伤，腹腔镜下行I期修复或开腹修复，T管引流，但无并发症。19例中3例IOC误读及4例未行IOC患者中发生迷走胆管损伤2例，胆总管完全离断1例，胆总管完全离断合并胆道缺损2例，本组有2例损伤发生于IOC后，结论：行IOC并正确阅读可及时发现腹腔镜胆囊切除术中胆道错认所致的胆道损伤，从而防止随之可能发生的严重并发症。     

Serum interleukin 2 receptor levels in childhood acute lymphoblastic leukemia

The clinical significance of interleukin 2 receptor (IL2R) concentrations in serum was determined for 344 children with newly diagnosed acute lymphoblastic leukemia (ALL). Serum levels of IL2R in patients (267 to 80,000 U/mL, median 2,007 U/mL) were significantly higher than normal control values (170 to 738 U/mL, median 347 U/mL) (P less than .0001). Measurements in cases of T cell ALL were lower than in the non-T, non-B cases (P = .02). Among the 264 patients with non-T, non-B ALL, but not in those with T cell disease, higher serum IL2R levels (greater than 2,000 U/mL) were associated with a poorer treatment outcome (P = .04). In a multivariate analysis, serum IL2R level contributed independent prognostic information beyond that conveyed by leukocyte count, race, and age (P = .04). One explanation for these results is that soluble IL2R competes with normal lymphocyte- integrated IL2R for the ligand and thus could suppress host antitumor immunity.
