Active case detection and treatment of malaria in pregnancy using LAMP technology (LAMPREG): a pragmatic randomised diagnostic outcomes trial-study protocol.

INTRODUCTION: Malaria is one of the major public health problems in sub-Saharan Africa. It contributes significantly to maternal and fetal morbidity and mortality in affected countries. This study aims to evaluate the impact of enhanced case detection using molecular testing called loop-mediated isothermal amplification (LAMP) on birth outcomes in a prospective study design. METHODS AND ANALYSIS: A pragmatic randomised diagnostic outcomes trial will be conducted in several health institutes in different Ethiopian regions. Women (n=2583) in their first and second trimesters of pregnancy will be included in the study and individually randomised to the standard of care or enhanced case detection arms, and followed until delivery. Enrolment will encompass the malaria peak transmission seasons. In the standard of care arm, a venous blood sample will be collected for malaria diagnosis only in symptomatic patients. In contrast, in the intervention arm, mothers will be tested by a commercially available Conformité Européene (CE)-approved LAMP malaria test, microscopy and rapid diagnostic test for malaria regardless of their symptoms at each antenatal care visit. The primary outcome of the study is to measure birth weight. ETHICS AND DISSEMINATION: The study was approved by the following ethical research boards: Armauer Hansen Research Institute/ALERT Ethics Review Committee (FORM AF-10-015.1, Protocol number PO/05/20), the Ethiopia Ministry of Science and Higher Education National Research Ethics Review Committee (approval SRA/11.7/7115/20), the Ethiopia Food and Drug Administration (approval 02/25/33/I), UCalgary Conjoint Health Research Ethics Board (REB21-0234). The study results will be shared with the institutions and stakeholders such as the Ethiopia Ministry of Health, the Foundation for Innovative Diagnostics, WHO's Multilateral initiative on Malaria - Tropical Diseases Research (TDR-MIM), Roll Back Malaria and the Malaria in Pregnancy Consortium. The study results will also be published in peer-reviewed journals and presented at international conferences. TRIAL REGISTRATION NUMBER: NCT03754322.

Disease Surveillance Among U.S.-Bound Immigrants and Refugees - Electronic Disease Notification System, United States, 2014-2019.

PROBLEM/CONDITION: Each year, approximately 500,000 immigrants and tens of thousands of refugees (range: 12,000-85,000 during 2001-2020) move to the United States. While still abroad, immigrants, refugees, and others who apply for admission to live permanently in the United States must undergo a medical examination. This examination identifies persons with class A or B conditions. Applicants with class A conditions are inadmissible. Infectious conditions that cause an applicant to be inadmissible include infectious tuberculosis (TB) disease (class A TB), infectious syphilis, gonorrhea, and infectious Hansen's disease. Applicants with class B conditions are admissible but might require treatment or follow-up. Class B TB includes persons who completed successful treatment overseas for TB disease (class B0), those with signs or symptoms suggestive of TB but whose overseas laboratory tests and clinical examinations ruled out current infectious TB disease (class B1), those with a diagnosis of latent TB infection (LTBI) (class B2), and the close contacts of persons known to have TB disease (class B3). Voluntary public health interventions might also be offered during the overseas examination. After arriving in the United States, a follow-up TB examination is recommended for persons with class B TB. PERIOD COVERED: This report summarizes health information that was reported to CDC's Electronic Disease Notification (EDN) system for refugees, immigrants, and eligible others who arrived in the United States during 2014-2019. Eligible others are persons who although not classified as refugees (e.g., certain parolees, special immigrant visa holders, and follow-to-join asylees) are eligible for the same services and benefits as refugees. DESCRIPTION OF SYSTEM: The EDN system has both surveillance and programmatic components. The surveillance component is a centralized database that collects 1) health-related data from the overseas medical examination for immigrants with class A or B conditions and for all refugees and eligible others and 2) TB-related data from the postarrival TB examination. The programmatic component is a reporting system that sends arrival notifications to state and local health agencies in the jurisdiction where newly arriving persons have reported intending to live and provides state and local health agencies and other authorized users with medical data from overseas examinations. RESULTS: During 2014-2019, approximately 3.5 million persons moved to the United States from abroad, including 3.2 million immigrants, 313,890 refugees, and 95,993 eligible others. Among these, the overseas examination identified 139,683 persons (3,903 per 100,000 persons examined) with class B TB, 54 with primary or secondary syphilis (30 per 100,000 persons tested), 761 with latent syphilis (415 per 100,000 persons tested), and, after laboratory testing for gonorrhea was added in 2016, a total of 131 with gonorrhea (374 per 100,000 persons tested). Refugees were offered additional, voluntary interventions, including vaccinations and presumptive treatment for parasites. By 2019, first- and second-dose coverage with measles-containing vaccine were 96% and 80%, respectively. In refugee populations for whom presumptive treatment is recommended, up to 96% of refugees, depending on the specific regimen, were offered and accepted treatment. For the 139,683 persons identified overseas with class B TB, EDN sent arrival notifications and overseas medical data to the appropriate state or local health agency to facilitate postarrival TB examinations. Among 101,119 persons identified overseas as having class B0 TB (6,586) or class B1 TB (94,533), a total of 67,432 (67%) had a complete postarrival examination reported to EDN. Among 35,814 children aged 2-14 years identified overseas with class B2 TB, 20,758 (58%) had a complete postarrival examination reported to EDN. (Adults are not routinely tested for immune reactivity to Mycobacterium tuberculosis during the overseas medical examination.) Among those with a complete postarrival examination reported to EDN, the number with a diagnosis of culture-positive TB disease within the first year of arrival was 464 (688 cases per 100,000 persons examined) for those with class B0 or B1 TB and was 11 (53 cases per 100,000 persons examined) for children with class B2 TB. INTERPRETATION: During 2014-2019, the overseas medical examination system prevented importation of 6,586 cases of infectious TB, 815 cases of syphilis, and 131 cases of gonorrhea. When the examination is used to offer public health interventions, most refugees (up to 96%) accept the intervention. Postarrival follow-up examinations, which were completed for 88,190 persons and identified 475 cases of culture-positive TB, represent an important opportunity to further limit spread of TB disease in the United States by identifying and providing, if needed, preventive care for those with LTBI or treatment for those with disease. PUBLIC HEALTH ACTION: Federal, state, and local health departments and agencies should continue to use EDN data to monitor, evaluate, and improve health-related programs and policies aimed at U.S.-bound or recently arrived immigrants, refugees, and eligible others. Additional public health interventions that could be offered during the overseas medical examination should be considered (e.g., treatment for LTBI). Finally, for persons with class B TB, measures should be taken to identify and remove barriers to completing postarrival examinations to reduce risk for TB disease and community transmission, along with measures to encourage reporting of completed examinations for better data-driven decision-making.

The long-term impact of the Leprosy Post-Exposure Prophylaxis (LPEP) program on leprosy incidence: A modelling study.

BACKGROUND: The Leprosy Post-Exposure Prophylaxis (LPEP) program explored the feasibility and impact of contact tracing and the provision of single dose rifampicin (SDR) to eligible contacts of newly diagnosed leprosy patients in Brazil, India, Indonesia, Myanmar, Nepal, Sri Lanka and Tanzania. As the impact of the programme is difficult to establish in the short term, we apply mathematical modelling to predict its long-term impact on the leprosy incidence. METHODOLOGY: The individual-based model SIMCOLEP was calibrated and validated to the historic leprosy incidence data in the study areas. For each area, we assessed two scenarios: 1) continuation of existing routine activities as in 2014; and 2) routine activities combined with LPEP starting in 2015. The number of contacts per index patient screened varied from 1 to 36 between areas. Projections were made until 2040. PRINCIPAL FINDINGS: In all areas, the LPEP program increased the number of detected cases in the first year(s) of the programme as compared to the routine programme, followed by a faster reduction afterwards with increasing benefit over time. LPEP could accelerate the reduction of the leprosy incidence by up to six years as compared to the routine programme. The impact of LPEP varied by area due to differences in the number of contacts per index patient included and differences in leprosy epidemiology and routine control programme. CONCLUSIONS: The LPEP program contributes significantly to the reduction of the leprosy incidence and could potentially accelerate the interruption of transmission. It would be advisable to include contact tracing/screening and SDR in routine leprosy programmes.

Skin tests for the detection of Mycobacterial infections: achievements, current perspectives, and implications for other diseases.

Immunological and molecular advances have modernized diagnostic testing for many diseases. Although interferon gamma-release and polymerase chain reaction assays have been developed to detect Mycobacterium tuberculosis (Mtb) infection, purified protein derivative (PPD)-based tuberculin skin testing (TST) remains the most widely used method. Indeed, the TST is a simple and cost-effective tool that can be easily applied for widespread screening for Mtb infection. However, the lack of specificity has been a limitation of these tests, and, more recently, supply issues have arisen. Building upon the skin tests that historically have been used within TB and leprosy control programs, we discuss recent developments using modern technologies for improving mycobacterial skin testing as well as practical advantages inherent to the technique. Furthermore, we outline how this knowledge could be applied to develop similar tests that could benefit diagnostic strategies for other infections. KEY POINTS: • Skin testing provides a significantly cheaper alternative to most modern technologies. • Skin tests provide a lab-independent diagnostic strategy that can be widely administered. • Diseases for which T cell responses are more robust or durable than antibody responses are accessible for skin testing.

Leprosy post-exposure prophylaxis with single-dose rifampicin (LPEP): an international feasibility programme

Background: Innovative approaches are required for leprosy control to reduce cases and curb transmission of Mycobacterium leprae. Early case detection, contact screening, and chemoprophylaxis are the most promising tools. We aimed to generate evidence on the feasibility of integrating contact tracing and administration of single-dose rifampicin (SDR) into routine leprosy control activities. Methods The leprosy post-exposure prophylaxis (LPEP) programme was an international, multicentre feasibility study implemented within the leprosy control programmes of Brazil, India, Indonesia, Myanmar, Nepal, Sri Lanka, and Tanzania. LPEP explored the feasibility of combining three key interventions: systematically tracing contacts of individuals newly diagnosed with leprosy; screening the traced contacts for leprosy; and administering SDR to eligible contacts. Outcomes were assessed in terms of number of contacts traced, screened, and SDR administration rates. Findings Between Jan 1, 2015, and Aug 1, 2019, LPEP enrolled 9170 index patients and listed 179 769 contacts, of whom 174782 (97·2%) were successfully traced and screened. Of those screened, 22 854 (13·1%) were excluded from SDR mainly because of health reasons and age. Among those excluded, 810 were confirmed as new patients (46 per 10 000 contacts screened). Among the eligible screened contacts, 1182 (0·7%) refused prophylactic treatment with SDR. Overall, SDR was administered to 151 928 (86·9%) screened contacts. No serious adverse events were reported. Interpretation Post-exposure prophylaxis with SDR is safe; can be integrated into different leprosy control programmes with minimal additional efforts once contact tracing has been established; and is generally well accepted by index patients, their contacts, and health-care workers. The programme has also invigorated local leprosy control through the availability of a prophylactic intervention; therefore, we recommend rolling out SDR in all settings where contact tracing and screening have been established(AU).

A systematic review and meta-analysis of studies on the diagnostic accuracy and screening of tests to detect antimicrobial resistance in leprosy

Although multidrug therapy is considered an effective treatment for leprosy, antimicrobial resistance is a serious concern. We performed a systematic review of studies on the diagnostic accuracy and screening of tests for antimicrobial resistance in leprosy. This review was registered in PROSPERO (CRD42020177958). In April 2020, we searched for studies in the PubMed, EMBASE, Web of Science, Scopus, Scielo, and LILACS databases. A random effects regression model was used for the meta-analysis. We included 129 studies. Molecular tests for dapsone resistance had a sensitivity of 78.8% (95% confidence interval [CI] = 65.6−87.9) and a specificity of 97.0% (95% CI = 94.0−98.6). Molecular tests for rifampicin resistance had a sensitivity and specificity of 88.7% (95% CI = 80.0−93.9) and 97.3% (95% CI = 94.3−98.8), respectively. Molecular tests for ofloxacin resistance had a sensitivity and specificity of 80.9% (95% CI = 60.1−92.3) and 96.1% (95% CI = 90.2−98.5), respectively. In recent decades, no increase in the resistance proportion was detected. However, the growing number of resistant cases is still a clinical concern(AU).

The long-term impact of the leprosy post-exposure prophylaxis (LPEP) program on leprosy incidence: a modelling study

The Leprosy Post-Exposure Prophylaxis (LPEP) program explored the feasibility and impact of contact tracing and the provision of SDR to eligible contacts of newly diagnosed leprosy patients in states or districts of Brazil, India, Indonesia, Myanmar, Nepal, Sri Lanka and Tanzania. This study investigated the long-term impact of the LPEP program on the leprosy new case detection rate (NCDR). Our results show that LPEP could reduce the NCDR beyond the impact of the routine leprosy control programme and that many new cases could be prevented. The benefit of LPEP increases gradually over time. LPEP could accelerate the time of reaching predicted NCDR levels of 2040 under routine program by up to six years. Furthermore, we highlighted how the impact varies between countries due to differences in the number of contacts per index patient screened and differences in leprosy epidemiology and national control programme. Generally, including both household contacts and neighbours (> 20 contacts per index patient) would yield the highest impact.

Activity limitation and social participation restriction among leprosy patients in Boru Meda Hospital, Amhara Region, Ethiopia.

BACKGROUND: Although Ethiopia eliminated leprosy as public health problem 20 years ago, still more than 3000 new cases are reported annually. Leprosy related disability affects patients' day to day physical activities and their participation in social activities. Assessing the degree of activity limitation and social participation is recommended to show disability and assess the efficacy of rehabilitation efforts. METHODOLOGY AND PRINCIPAL FINDING: A hospital based cross sectional study was conducted among a total of 305 leprosy patients. Data were collected by face to face interview using Screening of Activity Limitation and Safety Awareness (SALSA) scale and participation scale. The analysis was done with SPSS version 25. Descriptive statistics was done and then binary logistic regression was used to identify factors associated with activity limitation as well as participation limitation. Most patients (219, 71.8%) had activity limitation; 41 (13.4%) with severe and 25 (8.2%) with extreme limitations. More than half of patients (168, 55.1%) were suffering from participation restriction; with 43 (14.1%) having severe restriction and 30 (9.8%) extreme restriction. Older age, low educational status, distance from treatment center, time of treatment and higher Eye, Hand, Foot disability score were associated with activity limitation. Similarly, older age, low educational status and being unmarried were significantly associated with participation restriction. CONCLUSION: This study revealed that activity limitation and participation restriction are common among leprosy patients. Earlier diagnosis and improved rehabilitative services may help to decrease activity limitation, whereas community rehabilitation may improve social participation. The old and centralized leprosy rehabilitation services need to be decentralized and backed with modern equipment and trained staffs.

Distribuição espacial dos casos de hanseníase no município de Sobral, Ceará, de 2010 a 2017 / Spatial distribution of leprosy cases in the municipality of Sobral, state of Ceará from 2010 to 2017 / Distribución espacial de casos de lepra en el municipio de Sobral, Ceará, de 2010 a 2017

Este artigo tem como objetivo analisar a distribuição espacial dos casos de hanseníase no município de Sobral, Ceará, entre 2010 e 2017, utilizando técnicas de geoprocessamento. Trata-se de um estudo epidemiológico ecológico, de referência temporal transversal com abordagem quantitativa, realizado no município de Sobral, CE. Elegeu-se como participantes do estudo pacientes diagnosticados com hanseníase no município de Sobral, de 2010 a 2017, e utilizou-se de geoprocessamento para análise espacial. Foram notificados durante o período do estudo um total de 750 casos novos. O ano de 2012 foi o que registrou maior número de diagnósticos e uma taxa de detecção de 52,81 por 100 mil habitantes, o que demonstra a hiperendemicidade do município. Além disso, identificou-se que a maioria dos casos ocorre nos perfis de sexo masculino, baixa escolaridade, zona urbana e casos novos. Já a análise espacial demonstra que a maioria dos bairros apresentou pelo menos um caso de hanseníase durante os anos estudados, sendo que a sede apresenta uma área endêmica para a transmissão da hanseníase positivas. O município, durante o período estudado, apresentou uma evolução favorável da doença, com os dois últimos anos registrando taxa muito alta de detecção da hanseníase. Dessa forma, confirma-se a endemicidade do município e demonstra-se que as ações implementadas estão sendo eficazes, com diagnóstico precoce, conclusão do tratamento e rastreamento dos contatos.

This article seeks to analyze the spatial distribution of leprosy cases in the municipality of Sobral, state of Ceará, from 2010 to 2017, using geoprocessing techniques. This is an epidemiological, ecological study of transversal temporal reference with a quantitative approach conducted in the municipality of Sobral, Ceará. Patients diagnosed with leprosy in the municipality of Sobral from 2010 to 2017 and use of geoprocessing for spatial analysis were chosen as study participants. In total, 750 new cases were notified during the study period, of which the year 2012 had the highest number of diagnoses and a detection rate of 52.81 per 100 thousand inhabitants, which demonstrates the hyperendemicity of the municipality, besides the male prevalence, low education, urban area and new cases. The spatial analysis shows that most neighborhoods have at least one case of leprosy during the years studied, and the headquarters has an endemic area for the transmission of positive leprosy. The municipality during the study period showed a favorable evolution of the disease, with the last two years presenting a very high rate of detection of leprosy, which confirms the endemicity of the municipality and demonstrates that the implemented actions are being effective, with early diagnosis, completion of treatment and tracking of contacts.

Incidence of and Factors Associated With Leprosy Among Household Contacts of Patients With Leprosy in Brazil.

Importance: Despite progress toward reducing global incidence, leprosy control remains a challenge in low- and middle-income countries. Objective: To estimate new case detection rates of leprosy among household contacts of patients with previously diagnosed leprosy and to investigate its associated risk factors. Design, Setting, and Participants: This population-based cohort study included families registered in the 100 Million Brazilian Cohort linked with nationwide registries of leprosy; data were collected from January 1, 2007, through December 31, 2014. Household contacts of patients with a previous diagnosis of leprosy from each household unit were followed up from the time of detection of the primary case to the time of detection of a subsequent case or until December 31, 2014. Data analysis was performed from May to December 2018. Exposures: Clinical characteristics of the primary case and sociodemographic factors of the household contact. Main Outcomes and Measures: Incidence of leprosy, estimated as the new case detection rate of leprosy per 100 000 household contacts at risk (person-years at risk). The association between occurrence of a subsequent leprosy case and the exposure risk factors was assessed using multilevel mixed-effects logistic regressions allowing for state- and household-specific random effects. Results: Among 42 725 household contacts (22 449 [52.5%] female; mean [SD] age, 22.4 [18.5] years) of 17 876 patients detected with leprosy, the new case detection rate of leprosy was 636.3 (95% CI, 594.4-681.1) per 100 000 person-years at risk overall and 521.9 (95% CI, 466.3-584.1) per 100 000 person-years at risk among children younger than 15 years. Household contacts of patients with multibacillary leprosy had higher odds of developing leprosy (adjusted odds ratio [OR], 1.48; 95% CI, 1.17-1.88), and the odds increased among contacts aged 50 years or older (adjusted OR, 3.11; 95% CI, 2.03-4.76). Leprosy detection was negatively associated with illiterate or preschool educational level (adjusted OR, 0.59; 95% CI, 0.38-0.92). For children, the odds were increased among boys (adjusted OR, 1.70; 95% CI, 1.20-2.42). Conclusions and Relevance: The findings in this Brazilian population-based cohort study suggest that the household contacts of patients with leprosy may have increased risk of leprosy, especially in households with existing multibacillary cases and older contacts. Public health interventions, such as contact screening, that specifically target this population appear to be needed.

Integrated approach in the control and management of skin neglected tropical diseases in three health districts of Côte d'Ivoire.

BACKGROUND: Neglected tropical diseases (NTDs) comprise 20 communicable diseases that are prevalent in rural poor and remote communities with less access to the health system. For effective and efficient control, the WHO recommends that affected countries implement integrated control interventions that take into account the different co-endemic NTDs in the same community. However, implementing these integrated interventions involving several diseases with different etiologies, requiring different control approaches and driven by different vertical programs, remains a challenge. We report here the results and lessons learned from a pilot test of this integrated approach based on integrated screening of skin diseases in three co-endemic health districts of Côte d'Ivoire, a West African country endemic for Buruli ulcer, leprosy and yaw. METHOD: This cross-sectional study took place from April 2016 to March 2017 in 3 districts of Côte d'Ivoire co-endemic for BU, leprosy and yaws. The study was carried out in 6 stages: identification of potentially co-endemic communities; stakeholder training; social mobilization; mobile medical consultations; case detection and management; and a review meeting. RESULTS: We included in the study all patients with skin signs and symptoms at the screening stage who voluntarily accepted screening. In total, 2310 persons screened had skin lesions at the screening stage. Among them, 07 cases were diagnosed with Buruli ulcer. There were 30 leprosy cases and 15 yaws detected. Other types of ulcerations and skin conditions have been identified and represent the majority of cases detected. We learned from this pilot experience that integration can be successfully implemented in co-endemic communities in Côte d'Ivoire. Health workers are motivated and available to implement integrated interventions instead of interventions focused on a single disease. However, it is essential to provide capacity building, a minimum of drugs and consumables for the care of the patients identified, as well as follow-up of identified patients, including those with other skin conditions. CONCLUSIONS: The results of this study show that the integration of activities can be successfully implemented in co-endemic communities under the condition of staff capacity building and minimal care of identified patients.

[Leprosy in Amazonas-impressions of the National Leprosy Program]. / Lepra in Amazonien ­ Eindrücke aus einem Kontrollprogramm.

Due to the often late detection and the neurological disability as a consequence of the disease, leprosy plays an important role in the public health system of emerging countries with the highest prevalence such as India and Brazil. The National Leprosy Control Program of the Ministry of Health and the Health Institutions of the Federal States in Brazil has implemented a strategy to ensure successful treatment of people in rural areas both at the preventive and curative level. A successful screening program, timely treatment of patients according to the stage of disease, and the introduction of preventive measures have significantly reduced the prevalence of leprosy in Brazil over the last 20 years. Due to limited medical care and socioeconomic weakness in the Amazon region in Brazil, the early eradication of leprosy does not seem to be currently realistic.

Community health care workers in pursuit of TB: Discourses and dilemmas.

Community-led tuberculosis (TB) active case finding is widely promoted, heavily funded, but many efforts fail to meet expectations. The underlying reasons why TB symptom screening programs underperform are poorly understood. This study examines Nigerian stakeholders' insights to characterize the mechanisms, enabling structures and influences that lead programs to succeed or fail. Eight focus group discussions were held with Community Health Workers (CWs) from four models of community-based TB screening and referral. In-depth interviews were conducted with 2 State TB program managers, 8 Community based organizations (CBOs), and 6 state TB and Leprosy Local Government supervisors. Transcripts were coded using Framework Analysis to assess how divergent understandings of CWs' roles, expectations, as well as design, political and structural factors contributed to the observed underperformance. Altruism, religious faith, passion, and commitment to the health and well-being of their communities were reasons CWs gave for starting TB symptom screening and referral. Yet politicized or donor-driven CWs' selection processes at times yielded implementers without a firm grounding in TB or the social, cultural, and physical terrain. CWs encountered suspicion, stigma, and hostility in both health facilities and communities. As the interface between the TB program and communities, CWs often bore the brunt of frustrations with inadequate TB services and CBO/iNGO collaboration. Some CWs expended their own social and financial capital to cover gaps in the active case finding (ACF) programs and public health services or curtailed their screening activities. Effective community-led TB active case finding is challenging to design, implement and sustain. Contrary to conventional wisdom, CWs did not experience it as inherently empowering. Sustainable, supportive models that combine meaningful engagement for communities with effective program stewardship and governance are needed. Crucially effective and successful implementation of community-based TB screening and referral requires a functional public health system to which to refer.

Association between the Rosén and Lundborg Score and the Screening Activity Limitation and Safety Awareness scale in hand functional evaluation of patients with leprosy diagnosis.

PURPOSE: To evaluate the association of results from the Rosén and Lundborg Score and the screening activity limitation and Safety Awareness scale for the assessment of hand in patients diagnosed with leprosy. METHOD: An association between the Rosén and Lundborg Score and the Screening Activity Limitation and Safety Awareness scale for hand was evaluated in a cross-section study with 25 people of a mean age of 51 years old (SD 14), undergoing drug treatment for leprosy. RESULTS: The mean quantitative score in the Screening Activity Limitation and Safety Awareness scale was 27.9 (SD 10.5). Rosén and Lundborg Score for the median nerve were 2.43 (SD 0.38) on the right hand and 2.41 (SD 0.54) on the left hand whilst for the ulnar nerve, the scores observed were 2.33 (SD 0.42) for the right hand and 2.31 (SD 0.61) for the left hand. Significant correlations between the two instruments in assessment of the median and ulnar nerves on both hands were found. CONCLUSIONS: Due to the association found between the scales, the Rosén and Lundborg Score may be used in assessment of the hand in patients diagnosed with leprosy, as a tool to assist the result evaluation after the drug treatment, surgical treatment, rehabilitation and follow-up in the hand dysfunction in leprosy. Implications for Rehabilitation The leprosy inflammatory neuropathy may cause limitations and disabilities related to hand functions of patients. Instruments with quantitative scores provide a reliable basis for therapeutic intervention prognosis. New evaluation methods promote a better monitoring of treatment and hand function evolution of people with leprosy.

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.

Evidence of hidden leprosy in a supposedly low endemic area of Brazil.

OBJECTIVES: Show that hidden endemic leprosy exists in a municipality of inner São Paulo state (Brazil) with active surveillance actions based on clinical and immunological evaluations. METHODS: The study sample was composed by people randomly selected by a dermatologist during medical care in the public emergency department and by active surveillance carried out during two days at a mobile clinic. All subjects received a dermato-neurological examination and blood sampling to determine anti-PGL-I antibody titers by enzyme-linked immunosorbent assay (ELISA). RESULTS: From July to December 2015, 24 new cases of leprosy were diagnosed; all were classified as multibacillary (MB) leprosy, one with severe Lucio's phenomenon. Seventeen (75%) were found with grade-1 or 2 disability at the moment of diagnosis. Anti-PGL-I titer was positive in 31/133 (23.3%) individuals, only 6/24 (25%) were positive in newly diagnosed leprosy cases. CONCLUSIONS: During the last ten years before this study, the average new case detection rate (NCDR) in this town was 2.62/100,000 population. After our work, the NCDR was raised to 42.8/100,000. These results indicate a very high number of hidden leprosy cases in this supposedly low endemic area of Brazil.

RESULTS From July to December 2015, 24 new cases of leprosy were diagnosed; all were classified as multibacillary (MB) leprosy, one with severe Lucio's phenomenon. Seventeen (75%) were found with grade-1 or 2 disability at the moment of diagnosis. Anti-PGL-I titer was positive in 31/133 (23.3%) individuals, only 6/24 (25%) were positive in newly diagnosed leprosy cases. CONCLUSIONS During the last ten years before this study, the average new case detection rate (NCDR) in this town was 2.62/100,000 population. After our work, the NCDR was raised to 42.8/100,000. These results indicate a very high number of hidden leprosy cases in this supposedly low endemic area of Brazil.
