Skin disorders among children living in orphanage centres in Dar es Salaam, Tanzania

Prevalence of Sarcoptes scabiei infestation and its associated factors among primary school children: A school-based cross-sectional survey in the Rufiji district, Tanzania

Objectives

This study aimed to investigate the prevalence of Sarcoptes scabiei infestation and its associated factors among primary school children (PSC) in the Rufiji district.

Methods

A quantitative school-based cross-sectional study was conducted among 447 PSC in the Rufiji district. The prevalence of scabies among PSC was determined by clinical examination and by microscopic examination of skin samples for the presence of S. scabiei. A structured questionnaire was used to gather data on factors associated with S. scabiei infestation. Descriptive analysis, Fisher's exact, chi-square tests, and logistic regression analysis were used to analyze the data.

Results

The prevalence of scabies was 2.0%. Of the assessed factors, only physical contact with a person having itchy skin lesions (Adjusted Odds Ratio [AOR]=4.04, 95%CI 4.39-12.50) and infrequency of changing clothes before laundry (AOR=2.99, 95%CI 1.35-4.94) were significantly associated with scabies. The majority of participants demonstrated low levels of knowledge, with half exhibiting poor attitudes and inappropriate healthcare-seeking behaviors.

Conclusions

There was an ongoing transmission of scabies among PSC in the Rufiji district, with the factors associated with the transmission being physical contact with a person who had an itchy skin lesion and the infrequency of changing clothes before laundry. Therefore, there is a need for regular clinical screening and treatment of positive cases with preventive measures on contact and provision of health education.

A Cross Sectional Survey for Dermatoses in Children and Adolescents Residing in Orphanages in Urban Tirunelveli, Tamil Nadu, India

Context:

Skin diseases are a major cause of public concern among underprivileged people residing in orphanages. There is a need for community-based study for dermatoses in orphanages as the literature is scarce at the national and international levels.

Aims:

For profiling of various dermatoses to generate information on general health, nutritional status, and sanitation, and to educate about personal skin hygiene and care to inmates in urban child orphanages.

Settings and Design:

A cross-sectional study was conducted at 18 urban child orphanages in Tirunelveli city for 1 month.

Methods and Material:

A predesigned proforma was prepared and the demographic details regarding the inmates were obtained and they were screened under natural light for skin, hair, nail, and oral disorders as well as their built, nourishment, height, and weight were measured and recorded in tabulations.

Statistical Analysis Used:

Descriptive statistical analysis was followed for describing the prevalence of dermatoses and the age group affected which are explained in percentages and ratios.

Results:

Out of a total of 850 inmates, 93 (11%) were of 5–9 years and 757 (89%) were of 10–19 years. Among them, 330 (39%) were males and 520 (61%) were females. Overall, the inmates affected with dermatoses were 360 (42.4%) and infectious dermatoses were seen in 218 inmates (60.5%) and non-infectious dermatoses were seen in 142 inmates (39.5%). Adolescent females were more commonly affected and the commonest dermatoses observed were pediculosis capitis (13.6%) followed by acne vulgaris (8.1%) and in adolescent males, scabies (7.1%) was the commonest. No psychocutaneous disorders were encountered.

Conclusions:

Infections and infestations are common in orphanages due to a lack of awareness of personal hygiene and self-care practices. They should be given health education in order to reduce the disease burden in children living in orphanages which in turn decreases the disease burden at the community level.

Estimation of the burden of tinea capitis among children in Africa

Tinea capitis is a common and endemic dermatophytosis among school age children in Africa. However, the true burden of the disease is unknown in Africa. We aimed to estimate the burden of tinea capitis among children <18 years of age in Africa. A systematic review was performed using Embase, MEDLINE and the Cochrane Library of Systematic Reviews to identify articles on tinea capitis among children in Africa published between January 1990 and October 2020. The United Nation's Population data (2019) were used to identify the number of children at risk of tinea capitis in each African country. Using the pooled prevalence, the country-specific and total burden of tinea capitis was calculated. Forty studies involving a total of 229,086 children from 17/54 African countries were identified and included in the analysis. The pooled prevalence of tinea capitis was 23% (95% CI, 17%-29%) mostly caused by Trichophyton species. With a population of 600 million (46%) children, the total number of cases of tinea capitis in Africa was estimated at 138.1 (95% CI, 102.0-174.1) million cases. Over 96% (132.6 million) cases occur in sub-Saharan Africa alone. Nigeria and Ethiopia with the highest population of children contributed 16.4% (n = 98.7 million) and 8.5% (n = 52.2 million) of cases, respectively. Majority of the participants were primary school children with a mean age of 10 years. Cases are mostly diagnosed clinically. There was a large discrepancy between the clinical and mycological diagnosis. About one in every five children in Africa has tinea capitis making it one of the most common childhood conditions in the region. A precise quantification of the burden of this neglected tropical disease is required to inform clinical and public health intervention strategies.

Burden of tinea capitis among children in Africa: protocol for a systematic review and meta-analysis of observational studies, 1990-2020

INTRODUCTION

Tinea capitis is the most common form of dermatophytosis among children, contributing significantly to the global burden of skin and hair infections. However, an accurate account of its burden in Africa, where most cases are thought to occur, is lacking. We aim to systematically evaluate the burden, aetiology and epidemiological trend of tinea capitis among children over a 30-year period in Africa.

METHODS AND ANALYSIS

A systematic review will be conducted using Embase, PubMed, African Journals Online, Web of Science and the Cochrane Library of Systematic Review. These resources will be used to identify studies published between 1990 and December 2020, which report the prevalence, aetiology and trend of tinea capitis among children younger than 18 years in Africa. Articles in English and French will be considered. Two independent reviewers will screen the articles for eligibility, and any discrepancies will be resolved by discussion and consensus between the authors. Methodological quality of all studies will be assessed and critically appraised. We will perform a metaregression to assess the impact of study characteristics on heterogeneity and also to correct the meta-analytical estimates for biases. A qualitative synthesis will be performed, and STATA V.16.0 software will be used to estimate the pooled prevalence and aetiology of tinea capitis. The Mann-Kendall trend test will be use to evaluate the trend in the prevalence of tinea capitis over the study period.

ETHICS AND DISSEMINATION

Ethical approval from an institutional review board or research ethics committee is not required for this systematic review and meta-analysis. The results will be published in a peer-reviewed journal and presented in conferences.
