Azithromycin resistance and its molecular characteristics in Neisseria gonorrhoeae isolates from a tertiary care centre in North India

Treatment guidelines for management of uncomplicated gonorrhoeae have been recently modified owing to alarming upsurge in azithromycin resistance. This study investigated the prevalence and genetic determinants of gonococcal azithromycin resistance in India. Four (5.7%) of 70 gonococcal isolates were resistant to azithromycin. Of 16 isolates investigated for molecular mechanisms of resistance, 13 (81.3%) and 6 (37.5%) isolates exhibited mutations in coding and promoter regions of mtrR gene, respectively. However, ermA, ermB and ermC genes or mutations in rrl gene were absent in all isolates. Azithromycin resistance is low in India posing no immediate threat to use of dual-therapy for syndromic management.     

Reducing sexual risk and promoting acceptance of men who have sex with men living with HIV in India: Outcomes and process evaluation of a pilot randomised multi-level intervention

ABSTRACT

HIV-positive men who have sex with men (HIV+MSM) in India need culturally-relevant interventions to promote safer sex. We tested a multi-level intervention among HIV+MSM that targeted individual, interpersonal, and community factors, based on the Social-Personal and Social Ecological Models. We conducted a 2?×?2 factorial RCT with 119 HIV+MSM randomised to receive either an individual-level intervention (ILI) using motivational interviewing to promote safer sex, a community-level intervention (CLI) to strengthen community norms toward safer sex and reduce stigma among MSM communities, a multi-level intervention combining the individual- and community-level interventions (ILI?+?CLI), or standard-of-care control. Participants completed pre- and post-intervention assessments of a composite sexual risk score and a process evaluation to assess fidelity and satisfaction. Out of the 119 HIV+MSM, 106 (89.0%) completed pre- and post-intervention assessments. Generalised Estimating Equation models showed that both CLI (Incidence Rate Ratio [IRR]?=?.67, 95% CI .47 to .96) and ILI?+?CLI (IRR?=?.66, 95% CI .48 to .91) groups had a statistically significant decrease in sexual risk compared to the standard-of-care. The interventions had high levels of fidelity and satisfaction. This pilot RCT demonstrated feasibility and potential effectiveness of a multi-level intervention that addresses individual, interpersonal and community-level contributors of sexual risk among HIV+MSM.     

The healing of femoral neck fractures in dogs

Summary This study evaluates healing fractures of the femoral neck in dogs by using standard radiography, intraosseous venography, India ink staining and histology.The 45 animals were divided into three groups, one of which was not treated, but in the other two the fracture was fixed with a screw or two Kirschner wires.Our results suggest that, when intraosseous venography was positive, India ink injection was also positive, and the late phase of fracture healing was reached.

Résumé Etude de la consolidation des fractures du col fémoral chez le chien à l'aide des radiographies standard, de la phlébographie osseuse, de la coloration par l'encre de Chine et de l'examen anatomopathologique. Les animaux ont été divisés en trois groupes, dans l'un la fracture n'a pas été traitée, dans les deux autres elle a été fixée soit par une vis, soit par deux broches de Kirschner. Les résultats tendent à montrer que lorsque la phlébographie est positive, la coloration par l'encre de Chine l'est également et que la phase ultime de la consolidation est atteinte.

     

Can the process indicators for emergency obstetric care assess the progress of maternal mortality reduction programs? An examination of UNFPA Projects 2000-2004.

BACKGROUND: In view of the disappointing progress made in the last 20 years in reducing maternal mortality in low-income countries and before going to scale in implementing the new evidence-based strategies, it is crucial to review and assess the progress made in pilot countries where maternal mortality reduction programs focused on emergency obstetric care. OBJECTIVE: To review the process indicators recommended for monitoring emergency obstetric care and their application in field situations, examining the conditions under which they can be used to assess the progress of maternal mortality reduction programs. METHODS: Five of the six UN recommended process indicators were monitored annually for 5 years in selected districts of Morocco, Mozambique, India and Nicaragua. Trends are presented and discussed. RESULTS: With specific variations due to different local situations in the four countries and in spite of variations in quality of data collection, all indicators showed a consistent positive trend, in response to the inputs of the programs. CONCLUSIONS: The UN process indicators for emergency obstetric care should continue to be promoted, but with two important conditions: (1) data collection is carefully checked for quality and coverage; (2) efforts are made to match process and outcome indicators (maternal and perinatal mortality, incidence of complications).     

Epilepsy in Ancient India

The ancient Indian medical system, Ayurveda, meaning science of life, is the oldest system of medicine in the world. Epilepsy is defined as Apasmara: apa, meaning negation or loss of; smara, meaning recollection or consciousness. Aura was recognized and was called Apasmara Poorva Roopa. A large number of symptoms indicative of aura were listed. Worthy of mention are subjective sensation of sounds, sensation of darkness, feeling of delusion, and dream-like state. An actual attack of Apasmara includes falling down; shaking of the hands, legs, and body; rolling up of the eyes; grinding of the teeth; and foaming at the mouth. Four major types of epilepsy based on the disturbance of doshas (humors) that govern the physiological and physiochemical activities of the body are mentioned. Apasmara is considered a dangerous disease that is chronic and difficult to treat. Several causes are mentioned. Treatment included correcting the etiological factors and dietary regimen and avoiding dangerous places that may result in injuries.     

Prevalence of metabolic syndrome in adolescents from a north Indian population.

AIMS: To estimate the prevalence and distribution of the metabolic syndrome (MS) in adolescents attending school in the north Indian city of Chandigarh. RESEARCH DESIGN AND METHODS: At total of 1083 adolescents attending school (aged 12-17 years) participated in a community-based cross-sectional survey. Anthropometric examination included height, weight, body mass index, waist circumference, hip circumference, waist-hip ratio and blood pressure measurement. A fasting blood sample was taken for measurement of glucose, insulin and lipid profile. Socio-demographic characteristics were investigated using a questionnaire. The metabolic syndrome was determined by the National Cholesterol Education Program Adult Treatment Panel III definition modified for age. RESULTS: The overall prevalence of MS in adolescents was 4.2%. However, the prevalence rose to 5.8% when the fasting plasma glucose cut-off was lowered to 5.5 mmol/l. There was no gender difference in the distribution of MS. When stratified by body mass index (BMI), 5.5% adolescents were overweight (BMI > or = 95th percentile), while 4% were at risk for overweight (BMI between 85th and 95th percentile). Of the overweight adolescents, 36.6% met the criteria for MS, while 11.5% at risk for overweight and only 1.9% of the normal population had MS (P < 0.0001). Low high-density lipoprotein was the most common and abdominal obesity the least common constituent of MS. There was a significant difference (P < 0.0001) between the prevalence of MS adolescents from low to high socio-economic strata. CONCLUSIONS: A substantial number (4.2%) of north Indian adolescents and 36.6% of overweight adolescents had MS. This poses a serious threat to the current and future health of these young people.     

Community survey of primary dystonia in the city of Kolkata, India.

An epidemiological study on dystonia has not been reported from India. As part of a major study to find out the prevalence of major neurological disorders in the large urban city of Kolkata, Eastern India, we planned to determine the prevalence of primary dystonia. The study design was a cross-sectional study of a sample population obtained through stratified random selection and conducted in a two-stage procedure of screening by a nonprofessional team followed by confirmation of screened positive cases by the study neurologist. A total population of 52,377 was screened, and 29 subjects with dystonia were diagnosed. Out of them 23 subjects had primary dystonias [crude prevalence rate (CPR), 43.91/100,000; 95% confidence interval (CI), 28.41-64.81; age-standardized rates to world standard population, 49.06 (95% CI,31.74-72.41)] and all cases were focal type and predominantly of limb dystonia variety. Mean onset of dystonias were earlier in women (43.5 years) as compared to men (46.6 years). Thus our study on primary dystonia shows higher prevalence when compared with that of many studies globally, predominantly of focal type, earlier onset among women, and more cases of limb dystonias when compared with more prominent blepharospasm and cervical dystonias in western reports.     

Use of epr oximetry with india ink to measure the po2 in the liver in vivo in mice

The partial pressure of oxygen (pO₂) of the liver in vivo in unanesthetized mice was determined using electron paramagnetic resonance (EPR) oximetry with India ink. The EPR spectra were obtained using a low-frequency (1.2 GHz) EPR spectrometer with a loop gap cavity resonator. The line width of the India ink used in this experiment was reversibly broadened by oxygen and was particularly sensitive to pO₂ below 30 torr. After the administration of India ink into the tail vein, the India ink particles were taken up mainly by Kupffer cells in the liver and in part by phagocytes in the spleen. The pO₂ measured in the normal liver was about 14 torr and was constant for the 2-week experimental period. The pO₂ decreased when measured at 1, 2, and 6 days after treatment with a hepatotoxin (carbon tetrachloride (CCI₄)); within 2 weeks, it returned almost to the initial level. Measurements by EPR at sacrifice of controls and CCI₄-treated mice indicated that more than 90% of the India ink went to the liver; the spleen contained 4.7% of total amount in control mice and 8.8% in CCI₄-treated mice when measured 2 weeks after the treatment. These data indicate the usefulness of India ink for measuring the pO₂ of the liver in vivo and that the pO₂ in the Kupffer cells is decreased when the liver is damaged by CCI₄.
