Renal dysfunction in septicemic newborns

The study was undertaken to assess the association and incidence of acute renal failure (ARF) in septicemic neonates. Thirty neonates with septicemia formed the subject matter. Neonates with renal dysfunction were labelled as ARF patients after non responsiveness to a fluid and a diuretic challenge. Renal function tests were also evaluated. Nearly 15% neonates with septicemia developed ARF which was predominantly oliguric in type. The mortality rate in the septicemic neonates with ARF was significantly high. Further the mortality in neonates with oliguric ARF was significantly higher than those with non-oliguric ARF.     

Human papilloma virus infection in Indian nasopharyngeal carcinomas in relation to the histology of tumour

Nasopharyngeal carcinoma (NPC) is a rare malignancy world-wide. It shows an increasing trend in the southern parts of India. Genetic alterations brought about by environmental factors, HPV and EBV are thought to be crucial for NPC carcinogenesis. This study reports for the first time the incidence of HPV infection in NPC in Southern India. Detection of HPV was carried out in 36 NPC and 10 adenoid lesions by immunohistochemical analysis. 38.8% of NPC were positive for HPV with higher positivity in WHO Type I and WHO Type II cancers. One among 10 adenoid lesions also showed presence of HPV. The patients belonged to low socio-economic status and had exposure to either tobacco or alcohol alone or in combination or kitchen smoke.     

Risk factors for HIV infection in injection drug users and evidence for onward transmission of HIV to their sexual partners in Chennai, India

OBJECTIVES: Determining HIV prevalence in injection drug users (IDUs) and their regular sex partners in Chennai, India. METHODS: A total of 226 IDUs and their regular sex partners were enrolled during April-July 2003. After informed consent was obtained, a semistructured questionnaire was administered and serum was tested for HIV antibody. RESULTS: The HIV seroprevalence was 30% (68/226) in IDUs and 5% in their regular sex partners (11/226). While in 25% of couples only the male partner was HIV positive, 5% of the couples were concordant for HIV infection and 70% were HIV negative. Fifty-seven percent of the HIV-positive IDUs and 45% of the HIV-infected women thought that they had "no chance" or "very little chance" of getting HIV, reflecting low HIV risk perception. More than 20% IDUs reported borrowing or lending of injection equipment. In univariate analyses "sex" and "condom use" with sex workers had no bearing but "more than twice a day injecting frequency," "history of incarceration," "tattoos," "recruitment from northern part of the city," and ever-injecting drugs in drug-selling places had significant association with HIV infection in IDUs. In an adjusted model, the odds of HIV infection were 2 times higher among IDUs who had ever injected drugs in drug-selling places and 6 times higher in those who were recruited from the northern part of central Chennai. CONCLUSION: Reducing sharing of injection equipment and unsafe tattooing through targeted and environmental interventions, increasing HIV risk perception, and promoting safer sex practices among IDUs and their sex partners are urgent program needs.     

Value of papanicolaou smear in detection of Chlamydia trachomatis infection

This study was undertaken to assess the value of Papanicolaou smear for the diagnosis of Chlamydia trachomatis infection. The study was both retrospective (groups I and II) and prospective (group III). Group I consisted of 41 smears with cytomorphological changes proposed by Gupta, Kiviat, or Shiina. Group II was a control group, consisting of 30 cytologically normal smears. All these smears were subjected to specific immunofluorescent (IF) staining under identical conditions to confirm the diagnosis. In group III, 40 consecutive duplicate cervical smears were collected from patients attending the Sexually Transmitted Disease Clinic. One smear was routinely examined, and the specific IF staining was done on the other smear. The results in all the three groups were analysed. It was concluded that Papanicolaou smear is not useful in the detection of Chlamydia trachomatis infection.     

Randomized comparison between fluconazole and itraconazole for the treatment of candidemia in a pediatric intensive care unit: a preliminary study.

OBJECTIVE: Candida bloodstream infections have shown an increase in hospitalized patients, especially those receiving intensive care. The effectiveness of various azoles, especially itraconazole, in treatment of candidemia has not been fully evaluated. Our objective was to compare the efficacy and safety of enterally administered itraconazole vs. fluconazole in treatment of candidemia. DESIGN: Randomized, double-blind, controlled trial. SETTING: Pediatric intensive care unit of a referral and teaching hospital. SUBJECTS: Forty-three pediatric patients with candidemia, INTERVENTION: Patients received either fluconazole (n = 22) or itraconazole (n = 21), about 10 mg/kg orally or through a gastric tube, and were monitored for clinical and mycological cure (sterile fungal blood culture), blood counts, and liver and renal functions. MEASUREMENTS AND MAIN RESULTS: The clinical characteristics of two groups were comparable. The cure rate was similar in both the groups: itraconazole 17 of 21 (81%) and fluconazole 18 of 22 (82%). Crude mortality rate (itraconazole 9.5% and fluconazole 13.6%) was also comparable in two groups of patients. The frequency of electrolyte disturbance was very low and similar in both the groups. Blood urea, creatinine, liver enzymes, and serum bilirubin were not adversely affected. CONCLUSIONS: Itraconazole was as effective as fluconazole in nosocomial candidiasis in children receiving intensive care and was devoid of serious side effects.
