A Comparative Trial of Single Dose Chemotherapy in Paucibacillary Leprosy Patients with Two to Three Skin Lesions.

A multicentric double-blind, controlled, clinical trial was carried out to compare the efficacy of a combination of rifampicin 600 mg plus ofloxacin 400 mg plus minocycline 100 mg (ROM) administered as single dose with that of standard WHO/MDT/PB six months regimen. The study subjects were 236 previously untreated, smear-negative patients, without nerve trunk involvement and having only two or three skin lesions. Randomization was done on individual patient basis. Results were analyzed for mean clincal score for improvement, marked clinical improvement and complete clinical cure at the time of release from treatment and at 12 months and 18 months of follow-up. Clinical improvement was seen in most patients in both regimens. Marked improvement (i.e., more than 90% reduction in clinical score) at 18 months was seen in 46.2% and 53.4% of the patients treated with ROM and standard regimens, respectively. But, significant difference in favour of standard PB regimen was seen in patients with three skin lesions and in patients in whom more than one body part was affected. Reversal reaction and adverse drug reactions were minimal in both groups

A European multicentre photopatch test study

BACKGROUND: The two most common agent groups currently responsible for photoallergic contact dermatitis (PACD) are organic ultraviolet (UV) absorbers in sunscreens and topical nonsteroidal anti-inflammatory drugs (NSAIDs). However, availability of information on the photoallergenic potential of these agents is scarce. OBJECTIVES: To obtain current information on the frequency of PACD to 19 organic UV absorbers and five topical NSAIDs, including newer agents, in common usage in Europe. METHODS: A prospective, multicentre photopatch test study was conducted with 1031 patients attending for investigation of suspected PACD in 30 centres across 12 European countries. RESULTS: A total of 346 PACD reactions in 200 (19·4%) subjects occurred. PACD was most commonly caused by the topical NSAIDs, ketoprofen (128 subjects) and etofenamate (59 subjects). Of the organic UV absorbers, octocrylene, benzophenone-3 and butyl methoxydibenzoylmethane most frequently elicited PACD. The 'newer' organic sunscreen absorbers rarely led to PACD. There appeared to be an association between the agents ketoprofen, octocrylene and benzophenone-3, with several subjects developing PACD to two or all three agents concomitantly. Allergic contact dermatitis (ACD) was less commonly observed than PACD, comprising 55 reactions in 47 (5%) subjects. Irritant reactions and photoaugmentation and photoinhibition of ACD occurred infrequently. CONCLUSIONS: The European multicentre photopatch test study has provided current information on the relative frequency of PACD to common photoallergens. Such data will be of value when deciding on which agents to include in a future European 'baseline' photopatch test series

Increasing proportion of carbapenemase-producing Enterobacteriaceae and emergence of a MCR-1 producer through a multicentric study among hospital-based and private laboratories in Belgium from September to November 2015

Carbapenemase-producing Enterobacteriaceae (CPE) strains have been increasingly reported in Belgium. We aimed to determine the proportion of CPE among Enterobacteriaceae isolated from hospitalised patients and community outpatients in Belgium in 2015. For the hospitalised patients, the results were compared to a previous similar survey performed in the same hospitals in 2012. Twenty-four hospital-based and 10 private laboratories collected prospectively 200 non-duplicated Enterobacteriaceae isolates from clinical specimens. All isolates were screened locally by carbapenem disk diffusion using European Committee on Antimicrobial Susceptibility Testing methodology. Putative CPE strains with inhibition zone diameters below the screening breakpoints were referred centrally for confirmation of carbapenemase production. From September to November 2015, we found a proportion of clinical CPE of 0.55% (26/4,705) and of 0.60% (12/1,991) among hospitalised patients and among ambulatory outpatients respectively. Klebsiella pneumoniae (26/38) and OXA-48-like carbapenemase (28/38) were the predominant species and enzyme among CPE. One OXA-48-producing Escherichia coli isolated from a hospital was found carrying plasmid-mediated MCR-1 colistin resistance. Compared with the 2012 survey, we found a significant increased proportion of clinical CPE (0.55% in 2015 vs 0.25% in 2012; p = 0.02) and an increased proportion of hospitals (13/24 in 2015 vs 8/24 in 2012) with at least one CPE detected. The study results confirmed the concerning spread of CPE including a colistin-resistant MCR-1 producer in hospitals and the establishment of CPE in the community in Belgium

Ocular sequelae of congenital toxoplasmosis in Brazil compared with Europe

Toxoplasmic retinochoroiditis appears to be more severe in Brazil, where it is a leading cause of blindness, than in Europe, but direct comparisons are lacking. Evidence is accumulating that more virulent genotypes of Toxoplasma gondii predominate in South America

Algorithms for converting estimates of child malnutrition based on the NCHS reference into estimates based on the WHO Child Growth Standards

<p>Abstract</p> <p>Background</p> <p>The child growth standards released by the World Health Organization (WHO) in 2006 have several technical advantages over the previous 1977 National Center for Health Statistics (NCHS)/WHO reference and are recommended for international comparisons and secular trend analysis of child malnutrition. To obtain comparable data over time, earlier surveys should be reanalyzed using the WHO standards; however, reanalysis is impossible for older surveys since the raw data are not available. This paper provides algorithms for converting estimates of child malnutrition based on the NCHS reference into estimates based on the WHO standards.</p> <p>Methods</p> <p>Sixty-eight surveys from the WHO Global Database on Child Growth and Malnutrition were analyzed using the WHO standards to derive estimates of underweight, stunting, wasting and overweight. The prevalences based on the NCHS reference were taken directly from the database. National/regional estimates with a minimum sample size of 400 children were used to develop the algorithms. For each indicator, a simple linear regression model was fitted, using the logit of WHO and NCHS estimates as, respectively, dependent and independent variables. The resulting algorithms were validated using a different set of surveys, on the basis of which the point estimate and 95% confidence interval (CI) of the predicted WHO prevalence were compared to the observed prevalence.</p> <p>Results</p> <p>In total, 271 data points were used to develop the algorithms. The correlation coefficients (R²) were all greater than 0.90, indicating that most of the variability of the dependent variable is explained by the fitted model. The average difference between the predicted WHO estimate and the observed value was <0.5% for stunting, wasting and overweight. For underweight, the mean difference was 0.8%. The proportion of the 95% CI of the predicted estimate containing the observed prevalence was above 90% for all four indicators. The algorithms performed equally well for surveys without the entire age coverage 0 to 60 months.</p> <p>Conclusion</p> <p>To obtain comparable data concerning child malnutrition, individual survey data should be analyzed using the WHO standards. When the raw data are not available, the algorithms presented here provide a highly accurate tool for converting existing NCHS estimates into WHO estimates.</p

Timing of Menarche in Girls Adopted from China: a Cohort Study

Background: Girls adopted internationally from some states have been found to have high rates of early puberty, including early menarche. Explanations for the link between international adoption and early puberty include post-adoption catch-up growth triggering puberty, and under-recorded age. Methods: We compared menarcheal age in a cohort of 814 girls adopted from China into North America against menarcheal ages in girls in China. Adoptive parents provided survey data on their daughters’ weight in 2005 and on menarcheal status and age at menarche in 2011. Results: Estimated median age at menarche for adopted Chinese girls is 12.37y (95% CI: 11.84-13.00y). Estimated prevalence of menarcheal age ≤10.00y for adopted girls is 3%. These findings are similar to published findings on non-adopted Chinese girls. The distribution of menarche of adopted girls and non-adopted girls at the estimated incidence rates P3-P97 are also similar. Among the 609 girls whose parents reported on their weight shortly after adoption, 148 (24.3%) were –2SD or more below the median weight in the WHO weight-for-age tables. The proportion of these girls who had attained menarche was not statistically different from other girls. Conclusions: For girls adopted from China, the age of menarche, the percentage of girls attaining menarche <10y and the distribution of menarcheal age are all similar to Chinese girls growing up in China

Association between congenital toxoplasmosis and parent-reported developmental outcomes, concerns, and impairments in 3 year old children

Background: Information is lacking on the effects of congenital toxoplasmosis on development, behavior, and impairment in later childhood, as well as on parental concerns and anxiety. This information is important for counselling parents about the prognosis for an infected child and for policy decisions on screening. Methods: We prospectively studied a cohort of children identified by screening for toxoplasmosis in pregnant women or neonates between 1996 and 2000 in ten European centers. At 3 years of age, parents of children with and without congenital toxoplasmosis were surveyed about their child's development, behavior, and impairment, and about parental concerns and anxiety, using a postal questionnaire. Results: Parents of 178/223 (80%) infected, and 527/821 (64%) uninfected children responded. We found no evidence that impaired development or behavior were more common in infected children, or that any potential effect of congenital toxoplasmosis was masked by prenatal treatment. Parents of infected children were significantly more anxious and reported more visual problems in their children. Conclusion: On average, children aged three to four years with congenital toxoplasmosis identified by screening and treated during infancy in this European setting had risks of abnormal development and behavior similar to uninfected children. Parental anxiety about infected children needs to be addressed by clinicians. Future studies with longer follow up and clinician-administered assessments may be better able to detect any subtle differences in child outcomes
