Résumé

Background & objectives: Acute nongonococcal urethritis (NGU) is one of the commonest sexually transmitted infections affecting men. The role of genital mycoplasmas including Mycoplasma genitalium in HIV infected men with NGU is still not known. The aim of this study was to determine the isolation pattern/detection of genital mycoplasma including M. genitalium in HIV infected men with NGU and to compare it with non HIV infected individuals. Methods: One hundred male patients with NGU (70 HIV positive, 30 HIV negative) were included in the study. Urethral swabs and urine samples obtained from patients were subjected to semi-quantitative culture for Mycoplasma hominis and Ureaplasama urealyticum, whereas M. genitalium was detected by PCR from urine. The primers MgPa1 and MgPa3 were selected to identify 289 bp product specific for M. genitalium. Chalmydia trachomatis antigen detection was carried out by ELISA. Results: M. genitalium and M. hominis were detected/isolated in 6 per cent of the cases. M. genitalium was more common amongst HIV positive cases (7.1%) as compared to HIV negative cases (3.3%) but difference was not statistically significant. Co-infection of C. trachomatis and U. urealyticum was found in two HIV positive cases whereas, C. trachomatis and M. hominis were found to be coinfecting only one HIV positive individual. M. genitalium was found to be infecting the patients as the sole pathogen. Interpretation & conclusions: Patients with NGU had almost equal risk of being infected with M. genitalium, U. urealyticum or M. hominis irrespective of their HIV status. M.genitalium constitutes one of the important causes of NGU besides other genital mycoplasmas.

Résumé

BACKGROUND AND OBJECTIVES: Though quinolones have been recommended as a single dose treatment for uncomplicated gonorrhoea, there have been reports of treatment failure with fluoroquinolones. In this study we determined the antimicrobial susceptibility levels of consecutive isolates of Neisseria gonorrhoeae to examine the emergence of ciprofloxacin resistance N. gonorrhoeae. METHODS: Minimum inhibitory concentration (MIC) of ciprofloxacin and other drugs (penicillin, tetracycline, ciprofloxacin and ceftriaxone) was determined by agar dilution method. MIC was interpreted according to the NCCLS guidelines. beta lactamase production was detected by iodometric method and chromogenic cephalosporin method using nitrocefin disc. RESULTS: A total of 45 consecutive isolates of N. gonorrhoeae were obtained from patients with suspected acute gonococcal uretheritis. Of the 45 isolates, 35 (77.7%) were resistant to ciprofloxacin, 16 (35.5%) showed MIC value greater than 8 microg/ml. All isolates were sensitive to ceftriaxone while 21 isolates (46.6%) were resistant to penicillin and 23 (51%) to tetracycline. Ten isolates (22%) were found to be beta-lactamase producers. INTERPRETATION AND CONCLUSION: Ciprofloxacin resistant N. gonorrhoeae is on the rise in and around Chandigarh (north India). Thus, periodic surveillance of susceptibility levels of N. gonorrhoeae is essential to prevent the dissemination of drug resistant strains in the community.

Résumé

Paired maternal and cord blood samples were collected at delivery from 150 women who received varying doses of tetanus toxoid during pregnancy. Tetanus specific IgM and IgG antibodies were measured in them by standard ELISA with a sensitivity for IgM of 0.001 mg/ml, and for IgG of 0.0003 IU/ml. In 22 infants an additional estimation of tetanus antibody was made 1 month after birth. The presence of specific IgM in 78% of cord samples established an active foetal immune response. The titre did not alter significantly with the number of TT doses given to the mother. Foetal IgM rose in 60% of cases at one month of age compared to cord blood levels. At this time IgG levels were uniformly diminished in accord with a maternally derived passively transferred antibody. No switch of foetal IgM to IgG production was evident. The foetal immune response thus did not confer active protection against tetanus.

Résumé

The records of seventeen neonates (13 males and 4 females) with osteomyelitis and septic arthritis, who were admitted over a 3 year period, were reviewed. Neither prematurity nor low birth weight seemed to be a predisposing factor. The majority of the neonates (88.2%) had some antecedent illness or were subjected to certain procedures in the neonatal period. Paucity of movement of limb, fever and local swelling of the joint were the most frequent presenting symptoms. Deep soft tissue swelling was the frequently noted radiographic change (58.8%). Bone scintigraphy was abnormal in 7 out of 11 cases. Of the 21 sites involved, femur and humerus accounted for 76.1% of cases. Four of seventeen neonates had multiple bone involvement. Arthritis was present in fifteen neonates. Of the organisms isolated, Staphylococcus aureus was the commonest.
