Childhood borderline lepromatous leprosy: a case report.

BACKGROUND: Leprosy in children is a strong indicator of the recent failure of leprosy control and disease transmission programs. For twenty-two years, leprosy has been declared `eliminated as a public health hazard,` yet new cases continue to emerge in endemic areas. The new case detection rate among the child population was recorded at 4.4 per million children. Because of their underdeveloped or neonatal immunity and exposure to intrafamilial contacts, children tend to be the most vulnerable population. CASE: We present a case of the borderline lepromatous type of leprosy in a 9-year-old Indonesian male patient with the chief complaint of three stiff fingers on his left hand that began four years ago and hypopigmented patches on the back and buttocks that began five years ago. In this case, there was a history of leprosy in his mother`s sister, who had died. Leprosy in the patient was suspected of possibly being transmitted from his mother`s sister who had intense contact with the patient. The results of bacteriological examination with Ziehl- Neelsen staining of tissue scrapings found acid-fast bacilli. He was treated with a multibacillary multidrug regimen for 12 months. Periodical observations after the patient received the treatment revealed no new spots on the patient`s skin, some of the previous hypopigmented patches seemed to fade, especially those on the back. CONCLUSIONS: In the absence of an effective vaccine, early diagnosis and treatment are critical in preventing disability and deformity and reducing the physical, psychosocial, and economic burden of the disease.

Evolution of anti-malaria policies and measures in P.R. China for achieving and sustaining malaria-free.

Malaria is a major public health threat worldwide, and it was also widely prevalent in the history in China, seriously endangering people's health and affecting socioeconomic development. China was certified malaria elimination in 2021 with unremitting efforts since the founding of the People's Republic of China in 1949. This great achievement has been another milestone in the fight against major infectious diseases following the elimination of smallpox, poliomyelitis, leprosy, filariasis, neonatal tetanus and blinding trachoma in China. This paper briefly introduces the malaria burden dynamics and the corresponding malaria transmission risk stratificantions, as well as systematically reviews the evolution of anti-malaria policies and measures from severe epidemic to elimination in China. Meanwhile, five key lessons in malaria control and elimination in China are also briefly summarized. All of the above provide evidences for promoting global malaria eradication and preventing reestablishment of malaria transmission, finally benefit all individuals still suffering from the scourge of malaria.

Educação e trabalho na saúde sob participação social organizada e disseminada: a acumulação das conferências livres nacionais 2022-2023 / Education and work in health under organized and disseminated social participation: the accumulation of national free conferences 2022-2023

A coletânea "Educação e trabalho na saúde sob participação social organizada e disseminada: a acumulação das conferências livres nacionais 2022 ­ 2023", reunida por Maria Luiza Jaeger, Ricardo Burg Ceccim e Priscila Viégas Barreto de Oliveira, é uma obra decorrente do cotejamento de seis conferências livres nacionais, realizadas entre final de 2022 e início de 2023, como parte da construção da 17ª Conferência Nacional de Saúde, das quais participou a Associação Científica Rede Unida […]. O foco da entidade é a Educação e Trabalho na Saúde, fazendo parte da comunidade de entidades/sociedades científicas com forte presença junto ao Conselho Nacional de Saúde, inclusive integrando várias de suas Comissões, em especial a Comissão Intersetorial de Recursos Humanos e Relações de Trabalho. A entidade também integra o Fórum de Entidades Nacionais de Trabalhadores da Área da Saúde, instância que congrega Conselhos, Federações e Associações presentes no campo da saúde. Considerada essa personalidade institucional, a Rede Unida integrou conferências nacionais livres onde o tema da Educação e Trabalho na Saúde formaram tópicos estratégicos ao debate dos rumos no Sistema Único de Saúde. […] A obra representa um esforço de memória e apoio ao exercício do controle social em saúde nos termos da Constituição Federal relativamente ao setor da saúde e especialmente no tocante à Lei Federal 8.142, de 28 de dezembro de 1990. A anotação "participação social organizada e disseminada" ao título da coletânea diz respeito à congregação de participantes país afora de modo orquestrado pelo Conselho Nacional de Saúde em um dispositivo inovador à democracia: a chancela às estratégias autogeridas, capazes de acumular engajamento, reflexão e contribuição cidadã às políticas públicas de saúde. Essa nova realidade certamente se tornará mais um patrimônio brasileiro aos sistemas de saúde. A coletânea inicia a acaba no escopo da Educação e Trabalho na Saúde, este é seu propósito: recolher da participação social organizada e disseminada as contribuições de um campo particular pouco reconhecido como campo nas áreas de Ensino da Saúde e da Saúde Coletiva. Contudo, um campo germinativo, potente e aglutinador à ciência, à docência, à intervenção e à inovação.

MiR-1290: a potential therapeutic target for regenerative medicine or diagnosis and treatment of non-malignant diseases.

MicroRNAs are a set of small non-coding RNAs that could change gene expression with post-transcriptional regulation. MiRNAs have a significant role in regulating molecular signaling pathways and innate and adaptive immune system activity. Moreover, miRNAs can be utilized as a powerful instrument for tissue engineers and regenerative medicine by altering the expression of genes and growth factors. MiR-1290, which was first discovered in human embryonic stem cells, is one of those miRNAs that play an essential role in developing the fetal nervous system. This review aims to discuss current findings on miR-1290 in different human pathologies and determine whether manipulation of miR-1290 could be considered a possible therapeutic strategy to treat different non-malignant diseases. The results of these studies suggest that the regulation of miR-1290 may be helpful in the treatment of some bacterial (leprosy) and viral infections (HIV, influenza A, and Borna disease virus). Also, adjusting the expression of miR-1290 in non-infectious diseases such as celiac disease, necrotizing enterocolitis, polycystic ovary syndrome, pulmonary fibrosis, ankylosing spondylitis, muscle atrophy, sarcopenia, and ischemic heart disease can help to treat these diseases better. In addition to acting as a biomarker for the diagnosis of non-malignant diseases (such as NAFLD, fetal growth, preeclampsia, down syndrome, chronic rhinosinusitis, and oral lichen planus), the miR-1290 can also be used as a valuable instrument in tissue engineering and reconstructive medicine. Consequently, it is suggested that the regulation of miR-1290 could be considered a possible therapeutic target in the treatment of non-malignant diseases in the future.

A Pandemia e o Trabalho em Saúde: vozes do cotidiano / The Pandemic and Health Work: everyday voices

Com esta obra buscamos apresentar ao leitor reflexões sobre a COVID -19 e seus impactos no mercado de trabalho, especialmente num contexto de desigualdade social, onde muitos trabalhadores de ocupações essenciais ou não precisaram se expor ao vírus para manter a sua sobrevivência e a de sua família. Ao final das análises, pontuamos a necessidade proteção dos trabalhadores em tempos de Covid, orientações para os serviços e gestores de saúde, com a finalidade de desencadear a discussão sobre a invisibilidade de muitos trabalhadores que ficaram desprotegidos pelas políticas sociais brasileiras durante a pandemia de COVID-19. Com esse conjunto de textos, esperamos ampliar a compreensão sobre os efeitos da pandemia nos trabalhadores e trabalhadoras e, ao mesmo tempo, ativar o pensamento para iniciativas que são visibilizadas pelas autoras e autores. Ou seja, mais do que buscar aprendizagem com a experiência trágica da pandemia, pretendemos também construir novas manhãs para o trabalho na saúde. Objetivo oportuno, já que estamos diante da preparação da 17ª Conferência Nacional de Saúde, que terá o tema "Garantir Direitos e Defender o SUS, a Vida e a Democracia ­ Amanhã Vai Ser Outro Dia". Acreditamos que a pandemia será memória, aprendizagem e mobilização para retomarmos a agenda da proteção do trabalho, ampliarmos a compreensão de que o trabalho é direito humano e não dependência do capital, expandirmos iniciativas de políticas de proteção da vida e avançarmos no processo civilizatório que é necessário, como bem nos lembrou Sérgio Arouca na abertura da 8ª Conferência Nacional de Saúde, para que o SUS seja possível. Por fim, nossa homenagem às trabalhadoras e trabalhadores que, asfixiados pela pandemia e órfãos da ação governamental responsável, tiveram suas vidas tomadas nesses anos. Especialmente àqueles que foram vitimados desde sua inserção no trabalho em saúde. Aliás, não somente aos que partiram, também a todas as pessoas que se ocupam do trabalho em saúde nos sistemas, redes e serviços de saúde, mas também nos pontos de atenção nos territórios, com trabalhos informais e, muitas vezes, invisíveis. A vocês, nossas palmas, nosso reconhecimento e nossa luta para novas manhãs!

Pustular lesions in the neonate: Focused diagnostic approach based on clinical clues.

Pustules in a neonate can be due to various causes. Though the majority of conditions causing pustules in a neonate are benign, it is essential to clearly differentiate these from serious ones. A systematic approach based on detailed history and clinical examination of the neonate along with basic laboratory evaluation narrows down diagnostic possibilities and aids in the correct diagnosis. This review outlines a step-by-step approach so as to avoid clinical dilemmas and unnecessary intervention.

Vozes, olhares e sentidos da Participação Social no SUS / Voices, looks and senses of Social Participation in the SUS

Olhando para a trajetória histórica compreende-se melhor a relação entre "Democracia e Saúde" estabelecida para 16ª Conferência Nacional de Saúde realizada em 2019, pois a luta pelo direito à saúde e a implementação do SUS está vinculada a busca pela redemocratização e a ampliação dos direitos sociais no Brasil. As instâncias do controle social se consolidaram no decorrer das três décadas de sua existência, os movimentos sociais, bem como, as mais diversas organizações da sociedade civil, ocuparam estes espaços e buscaram transformá-los numa arena democrática de defesa da sua concepção de saúde, de política pública, de Estado, de desenvolvimento e de direitos humanos.

In the footsteps of Albert Calmette: an ecological study of TB, leprosy and potential exposure to wild-type Mycobacterium bovis.

BACKGROUND: One hundred years ago, Albert Calmette developed an avirulent strain of Mycobacterium bovis, but there is no evidence that his BCG strain was more immunogenic than wild-type M. bovis. Geographic variations in BCG efficacy remain ill-understood. We hypothesized that exposure to M. bovis through unpasteurized milk might protect against Mycobacterium tuberculosis and Mycobacterium leprae. METHODS: After excluding high-income countries (with universal milk pasteurization) and microstates, an ecological study comprising 113 countries was conducted. National data were obtained from United Nations agencies and international organizations about milk production per capita (1980-1999) as a proxy for exposure to wild-type M. bovis, TB (2000-2019) and leprosy (2005-2019) incidence, HIV prevalence (2000-2019), human development index (2010), global hunger index (2010), neonatal BCG coverage (1980-1999), urbanization (2000) and temperature (1990-2020). Multiple linear regression analyses were performed using log-transformed variables. RESULTS: For TB, the association differed by region. An inverse association with milk production was seen in regions outside, but not within, sub-Saharan Africa, after adjustment for confounders. The incidence of leprosy was inversely associated with milk production when combining all countries, but the association was stronger in sub-Saharan Africa. CONCLUSIONS: Exposure to wild-type M. bovis through unpasteurized milk may provide cross-protection against M. tuberculosis and M. leprae and contribute to geographic disparities in BCG efficacy. This needs to be confirmed by individual-level studies.

1ª Conferência Nacional de Vigilância em Saúde: processo ascendente e participativo / 1st National Health Surveillance Conference: bottom-up and participatory process

Este livro foi organizado e produzido para documentar e expandir o acesso às deliberações da 1ª Conferência Nacional de Vigilância em Saúde, com a expectativa de que se tornem vivas no cotidiano de todas as pessoas em todo o território brasileiro. Afinal, sistematizar o trabalho que se realiza pelo controle social no SUS é fundamental, inclusive para ocupar a condição de relevância pública que a Constituição Brasileira de 1988 atribuiu às ações e serviços de saúde. Tornar esse trabalho visível e reconhecê-lo nessa condição tem a dupla finalidade de fortalecer o SUS como política de saúde do estado brasileiro, conquistada pela população em esforço e luta, e de consolidar a relação entre a saúde e a democracia, aqui expressa pela designação das necessidades nos diferentes territórios e de forma ascendente, materializando a diretriz que embasa a institucionalidade do aparelho estatal na definição constitucional de que a saúde é bem de todos e que os governos devem agir para preservá-la e fortalecê-la.

Tuberculosis vaccine BCG: the magical effect of the old vaccine in the fight against the COVID-19 pandemic.

Bacillus Calmette-Guérin (BCG) is a live attenuated M. bovis vaccine that was developed about 100 years ago by Albert Calmette and Camille Guérin. Many countries have been using the vaccine for decades against tuberculosis (TB). The World Health Organization (WHO) recommends a single dose of BCG for infants in TB endemic as well as leprosy high risk countries, and globally almost 130 million infants are vaccinated yearly. The role of BCG is well known in reducing neonatal and childhood death rates. Epidemiological and retrospective cross-sectional studies demonstrated that the BCG vaccination protects the children against respiratory tract infections and lowers the risk of malaria in children. In addition, BCG enhances IFN-γ and IL-10 levels, thus providing immunity against respiratory tract infection even in elderly people. The BCG is also known to provide nonspecific innate immunity against viruses and parasites, through an innate immune mechanism termed 'trained immunity' and is defined as the immunological recall of the innate immune system by epigenetic reprogramming. Based on these studies it is suggested that the BCG has the potential to act as a protective agent against COVID-19. Further proven safety records of BCG in humans, its adjuvant activity and low-cost manufacturing make it an attractive option to stop the pandemic and reduce the COVID-19 related mortality. In this review we discuss the heterologous effects of BCG, induction of trained immunity and its implication in development of a potential vaccine against COVID-19 pandemic.

[Elimination of infectious disease in China, past and future].

In the long history, infectious disease once caused huge disasters to human beings, not only resulting in serious impacts on public health, but even threatening socioeconomic development and national security. Since the founding of the People's Republic of China, China has attached great importance to the prevention and treatment of infectious disease and achieved remarkable achievements. This article mainly summarizes the historical progresses of the eradication of smallpox and the eliminations of polio, leprosy, filariasis, neonatal tetanus, blinding trachoma and malaria in China, and discusses the eliminations of the infectious diseases which can be conducted in the future.

Implementation of a Pregnancy Prevention Programme (PPP) with a Controlled Distribution System (CDS) for the Generic Teratogenic Phthalimides Thalidomide, Lenalidomide and Pomalidomide.

Thalidomide (α-phthalimidoglutaride) was marketed in the 1950s and early 1960s; it was promoted as a sedative-hypnotic agent with minimal hangover. It was available in some countries as an over-the-counter medicine. Publications reporting profound teratogenic effects with thalidomide brought about major revisions to the monitoring of the safety of medicines. As a consequence of previously unrecognised teratogenic effects, it has been estimated that over 12,000 children were born with a range of defects and disabilities, including severe congenital anomalies. Notably, it has been hypothesised that around 40% of babies with thalidomide-induced malformations born during the 1950s and 1960s died in the neonatal period. The commonest causes of death were atresia of the small bowel, cardiac or renal malformations. Nevertheless, phocomelia (as a typical manifestation of thalidomide´s teratogenic effects) has been reported once again after thalidomide was approved for use in areas where leprosy is endemic. As a result, thalidomide embryopathy remains an important topic in countries such as Brazil. Nowadays thalidomide is approved around the world for the treatment of a wide range of conditions, including leprosy, Crohn's disease, multiple myeloma, and certain malignant solid tumours. Second-generation immunmodulatory drugs including lenalidomide and pomalidomide have received approval for use in the management of various forms of neoplastic disease. Based on clinical experience with thalidomide and its derivatives, learnings have been transferred to further research on a subset of substituted phthalimides each of which has a high risk of causing teratogenic effects. This group of phthalimides is classified within regulatory science as human teratogens. In order to gain approval, a Pregnancy Prevention Programme (PPP), along with a Controlled Distribution System (CDS) is required. The challenges of PPPs in particular for a generic manufacturer have been described, including Raising of awareness, and education; Special aspects of data collection and evaluation; Ethically and socially relevant aspects, and Utilising existing information technology and infrastructure. This paper highlights the risks of unplanned pregnancies, provides information on the regulatory background, and regulatory expectations. Our aim is to provide insights and practical learnings that have impacted operational risk management with the teratogenic phthalimides. Opportunities are presented that may support the implementation of harmonised approaches for PPP and CDS using existing IT-systems across countries and companies.

Predictive nomogram for leprosy using genetic and epidemiological risk factors in Southwestern China: Case-control and prospective analyses.

BACKGROUND: There is a high incidence of leprosy among house-contacts compared with the general population. We aimed to establish a predictive model using these genetic factors along with epidemiological factors to predict leprosy risk of leprosy household contacts (HHCs). METHODS: Weighted genetic risk score (wGRS) encompassing genome wide association studies (GWAS) variants and five non-genetic factors were examined in a case-control design associated with leprosy risk including 589 cases and 647 controls from leprosy HHCs. We constructed a risk prediction nomogram and evaluated its performance by concordance index (C-index) and calibration curve. The results were validated using bootstrap resampling with 1000 resamples and a prospective design including 1100 HHCs of leprosy patients. FINDING: The C-index for the risk model was 0·792 (95% confidence interval [CI] 0·768-0·817), and was confirmed to be 0·780 through bootstrapping validation. The calibration curve for the probability of leprosy showed good agreement between the prediction of the nomogram and actual observation. HHCs were then divided into the low-risk group (nomogram score ≤ 81) and the high-risk group (nomogram score > 81). In prospective analysis, 12 of 1100 participants had leprosy during 63 months' follow-up. We generated the nomogram for leprosy in the validation cohort (C-index 0·773 [95%CI 0·658-0·888], sensitivity75·0%, specificity 66·8%). Interpretation The nomogram achieved an effective prediction of leprosy in HHCs. Using the model, the risk of an individual contact developing leprosy can be determined, which can lead to a rational preventive choice for tracing higher-risk leprosy contacts.
