Little Doctors: Agents of change in Indian rural communities.

The child-to-child approach to health advocacy is one that draws on the strengths and agency of children to make a positive impact within their communities. The approach has been popularly used for health education in low- and middle-income countries. This article describes the 'Little Doctors' program that implemented the child-to-child approach in the towns of KC Patty and Oddanchatram, located in remote hilly regions of Tamil Nadu, India starting in 1986 to train middle- and high school children to respond to diseases prevalent in their communities along with practices for preventative measures. The program involved sessions that used a combination of creative instructional methods to engage students and provided take-home messages for them to act on with their families and community. The program was successful in creating a creative learning environment for children, offering a shift from the traditional methods of classroom instruction. Students who successfully completed the program were awarded certificates as 'Little Doctors' in their communities. Although the program did not conduct formal evaluations of the program effectiveness, students reported successfully recalling complex topics such as early signs of diseases like tuberculosis and leprosy that were prevalent in the community during the time. The program experienced several challenges and had to be discontinued despite its continued benefits to the communities.

Skin disease prevalence study in schoolchildren in rural Côte d'Ivoire: Implications for integration of neglected skin diseases (skin NTDs).

BACKGROUND: Early detection of several skin-related neglected tropical diseases (skin NTDs)-including leprosy, Buruli ulcer, yaws, and scabies- may be achieved through school surveys, but such an approach has seldom been tested systematically on a large scale in endemic countries. Additionally, a better understanding of the spectrum of skin diseases and the at-risk populations to be encountered during such surveys is necessary to facilitate the process. METHODS: We performed a school skin survey for selected NTDs and the spectrum of skin diseases, among primary schoolchildren aged 5 to 15 in Côte d'Ivoire, West Africa. This 2-phase survey took place in 49 schools from 16 villages in the Adzopé health district from November 2015 to January 2016. The first phase involved a rapid visual examination of the skin by local community healthcare workers (village nurses) to identify any skin abnormality. In a second phase, a specialized medical team including dermatologists performed a total skin examination of all screened students with any skin lesion and provided treatment where necessary. RESULTS: Of a total of 13,019 children, 3,504 screened positive for skin lesions and were listed for the next stage examination. The medical team examined 1,138 of these children. The overall prevalence of skin diseases was 25.6% (95% CI: 24.3-26.9%). The predominant diagnoses were fungal infections (n = 858, prevalence: 22.3%), followed by inflammatory skin diseases (n = 265, prevalence: 6.9%). Skin diseases were more common in boys and in children living along the main road with heavy traffic. One case of multi-bacillary type leprosy was detected early, along with 36 cases of scabies. Our survey was met with very good community acceptance. CONCLUSION: We carried out the first large-scale integrated, two-phase pediatric multi-skin NTD survey in rural Côte d'Ivoire, effectively reaching a large population. We found a high prevalence of skin diseases in children, but only limited number of skin NTDs. With the lessons learned, we plan to expand the project to a wider area to further explore its potential to better integrate skin NTD screening in the public health agenda.

A study on knowledge, beliefs and attitude towards leprosy in students of Jaipur, Rajasthan.

The objective of this study was to determine the knowledge, beliefs and attitudes regarding leprosy in school students of Jaipur district. A cross-sectional study was conducted from August 2010 to February 2011 on 1199 students (rural and urban) studying in class 10th and above. The findings of this study showed fair knowledge in students about cause, signs and symptoms of leprosy but less knowledge about prevention and treatment of the disease. Myths and beliefs were more prevalent in rural students as compared to urban ones. Both the groups showed positive attitude toward leprosy with 30-50% students showing neutral approach but negative reaction was more in rural students. In conclusion the study highlights to emphasize on health education in students and improving knowledge to develop positive attitude towards leprosy.

Behavioral surveillance survey regarding human immunodeficiency virus/acquired immunodeficiency syndrome among high school and junior college students.

BACKGROUND AND AIMS: It is necessary to know the baseline knowledge, attitude, and practices about human immunodeficiency virus/acquired immunodeficiency syndrome among young people and the changes in these with intervention to guide prevention efforts. METHODS: A cross-sectional pre- and post-survey with health education as a method of intervention was carried out in four different randomly selected schools and junior colleges among the Class IX-XII students of both sex. Instrument developed by the World Health Organization (WHO)/UNAIDS in their best practice recommendations was used for data collection. RESULTS: Knowledge about all correct methods was present in 61.23% of the respondents. Knowledge of at least two methods of prevention was present in 70.31% of the respondents. Misconceptions about prevention were that good diet (33.42%), avoiding mosquito bite (49.71%) and avoiding public toilets (65.14%) could help in the prevention. With intervention, there was an improvement in the knowledge. However, the proportion of students with misconceptions did not come down. Correct knowledge about two methods of prevention also did not reach the WHO recommendation of 90%. CONCLUSION: It is very difficult to change the attitude and practices by a single health educational intervention and an ongoing behavior change communication is recommended.

The use of ML Flow test in school children diagnosed with leprosy in the district of Paracatu, Minas Gerais.

The detection rate of leprosy in the district of Paracatu is high in the age group under 15 years-old, including about 6.8/10,000 inhabitants in 2003, and classified as hyperendemic. The study aimed to analyze the application of the PGL-1 (ML Flow) serological test in 56 of 68 school-age patients of the public school system, diagnosed with leprosy through active case finding in Paracatu, Minas Gerais State (2004 to 2006), with 71% classified as paucibacillary. Of these, 85.2% lived in urban areas, 55.8% were female and the disease was predominant in the 10 to 14 year-old age group (95%CI: 0.49-0.89; chi(2)=7.373), with 15 (26.7%) presenting a positive ML Flow result. Five patients showed grade 1 disabilities in the borderline clinical form (40% ML Flow positive). The percentage of leprosy cases among household contacts was 46.4%, 44.9% presenting positive ML Flow test results. The study suggests incorporating the ML Flow test into the health services, since it assists in the operational classification of the disease and in the control of household contacts with positive test results, aimed at early detection of suspected leprosy cases.

The relation between seroprevalence of antibodies against phenolic glycolipid-I among school children and leprosy endemicity in Brazil.

Leprosy control programs would benefit expressively from an easy method to estimate disease prevalence and to assess the effect of leprosy control measures on disease prevalence. Determination of the seroprevalence of antibodies to PGL-I through school children surveys might be a useful indicator of leprosy prevalence at the district level. To investigate whether seropositivity rates could be related to leprosy detection rates and whether seropositivity could be used as a proximal indicator to predict the leprosy incidence in other areas, 7,073 school children in three different leprosy-endemic states in Brazil were tested. The results show a widely varying distribution of seropositivity in the communities independent of the number of leprosy cases detected. Seroprevalence was significantly lower at private schools. No differences in the patterns of seropositivity between ELISA and dipstick were observed. No correlation between leprosy detection rate and seropositivity rates could be established.

A relação entre soroprevalência de anticorpos contra o glicolipídeo fenólico-I entre crianças em idade escolar e endemicidade da hanseníase no Brasil / The relation between seroprevalence of antibodies against phenolic glycolipid-I among school children and leprosy endemicity in Brazil

Os programas de controle da hanseníase se beneficiariam de um método fácil para estimar prevalência e avaliar o impacto das ações de controle na prevalência da doença. A determinação da soroprevalência de anticorpos contra PGL-I através de estudos com crianças em idade escolar foi sugerida como indicador útil da taxa de prevalência da hanseníase a nível municipal.Para investigar se a soropositividade estaria associada aos coeficientes de detecção da hanseníase e se poderia ser usada como indicador da prevalência em outras áreas, 7.073 crianças em três estados endêmicos de hanseníase no Brasil foram testadas. Resultados mostram uma considerável variação da distribuição de soropositividade nas comunidades, independente do número de casos de hanseníase detectados. A soroprevalência foi significativamente menor nos colégios. Nenhuma diferença na distribuição da soropositividade determinada por ELISA ou dipstick foi observada. Nenhuma correlação entre o coeficiente de detecção da hanseníase e soropositividade pôde ser estabelecida.

[Active search for leprosy and other skin diseases in school children from Agua de Dios, Colombia]. / Búsqueda Activa de Lepra y de Otras Enfermedades de la Piel en Escolares de Agua de Dios, Colombia.

OBJECTIVE: Actively searching for leprosy, other skin diseases and BCG vaccination scars amongst school children from Agua de Dios, the municipality having the highest prevalence of leprosy in Colombia. METHODS: A clinical examination of the children was carried out by nurses, interns, general practitioners and experts on leprosy. Skin smear tests and skin biopsies were performed when the clinical findings suggested leprosy. Anti-phenolic glycolipid antibodies in blood were determined in special cases. RESULTS: 86 % of the 2 844 school children were examined; 833 had skin diseases and 16 % of these required evaluation by specialists. Four new cases of paucibacillary leprosy, two indeterminate and two primary polyneuritic cases were found. Pediculosis capitis, pityriasis alba, tinea versicolor, hypopigmented nevus, insect bites and miliaria were frequently detected. BCG vaccination scars were absent in 387 children; following several logistical problems, they were vaccinated. Four children had signs of childhood abuse. An 11-year-old girl presented hypopigmented mycosis fungoides. All diseases and conditions found were treated. The community received information regarding the results, emphasising the importance of an early diagnosis of leprosy. CONCLUSIONS: The incidence of leprosy found (16/10,000) was 123 times higher than the rest of the country's incidence. It is advisable to continue clinical examinations in Agua de Dios and research into risk factors for acquiring leprosy.

Leprosy among university and high school students in Benin City, Nigeria. A eight years review.

36 cases of leprosy were seen among University and High School students in the Skin Clinic of the University of Benin Teaching Hospital during an 8 years period (1982-1989). The male to female ratio was 2 to 1. Borderline tuberculoid and tuberculoid leprosy were the commonest form of presentation, seen in 66.6% of all cases. Borderline lepromatous and lepromatous leprosy were seen in 22% while indeterminate in 11% of cases. There has been a gradual reduction of new cases from a peak of about 8 cases in 1983 to one in 1989. Most patients complied with treatment and were able to continue their education with little or no hinderance.

[The level of knowledge about leprosy among university students]. / Nivel de conocimientos sobre la lepra en estudiantes universitarios.

A survey about leprosy was made in 1,000 students from the University of Guadalajara (Guadalajara, Jalisco, Mexico). There were considered clinical, preventive, social and etiological aspects. The results showed that the patient suffering leprosy is currently marginated. We suggest that this study should be carried out in other universities of Mexico, with purposes to verify the stigmata of this entity.
