ABSTRACT
Abstract INTRODUCTION: Describing the general aspects of American tegumentary leishmaniasis enables the identification of the epidemiological scenario of the disease and the development of preventive actions. METHODS: We analyzed the records of patients with American tegumentary leishmaniasis in north Paraná between 2010 and 2015. RESULTS: We identified 108 cases (mostly in 2014) with the following characteristics: male individuals, rural workers, and ages averaging 56.8 years. Isolated ulcerated lesions were predominant, and Glucantime® was the most frequently used drug. CONCLUSIONS: American tegumentary leishmaniasis remains endemic and affects mostly men found in areas surrounded by woods; its treatment is partially efficient considering its side effects and incidence of recurrences.

O objetivo deste estudo consistiu em analisar o perfil clínico de pacientes positivos para tuberculose através de um estudo epidemiológico, descritivo e retrospectivo, com base em dados secundários contidos em prontuários dos pacientes atendidos no Hospital Universitário de Londrina compreendendo de janeiro de 2010 a dezembro de 2014. Dos prontuários disponíveis para a análise no momento de estudo 86 casos eram positivos para tuberculose, sendo a maioria do sexo masculino (65/76%) com faixa etária compreendida entre 2 e 91 anos. Os principais sinais clínicos apresentados foram tosse (50/58%), febre (45/52%) e perda de peso (34/40%). Em relação à forma clinica, 58/67% dos pacientes apresentaram a forma pulmonar, e 28/33% a forma não pulmonar. Casos positivos para tuberculose em associação com HIV/AIDS corresponderam a 32/37%. Também foram relatados hábitos prejudiciais dos pacientes nos quais 30/34% eram tabagistas, 20/23% usuários de drogas e 14/16% etilistas. Diante da escassez de dados publicados referentes à tuberculose na nossa região e sua relevância para a saúde pública, nosso estudo contribui com os aspectos epidemiológicos principalmente em relação ao elevado número de casos de coinfecção com Vírus da Imunodeficiência Humana e pacientes com evolução a óbito, auxiliando assim, o desenvolvimento e implementação de campanhas ou projetos que visem o diagnóstico e tratamento precoce.
The objective of this study was to analyze the clinical profile of patients positive for tuberculosis through an epidemiological study, descriptive and retrospective, based on secondary data contained in medical records of patients that attended the Hospital Universitário de Londrina comprising from January 2010 to December 2014. From the medical records available for analysis at the moment of study 86 cases were positive for tuberculosis, being the majority male (65/76%) with age group comprised between 2 to 91 years. The main symptoms presented were cough (50/58%), fever (45/52%) and weight loss (34/40%). Regarding the clinical form, 58/67% of the patients presented the pulmonary form, and 28/33% the non-pulmonary form. Positive cases for tuberculosis in association with HIV/AIDS corresponded to 32/37%. Harmful habits were also reported in patients in which 30/34% were smokers, 20/23% drug users and 14/16% were alcoholics. Against scarcity of published data referring to tuberculosis in our region and its relevance to public health, our study contributes to the epidemiological aspects mainly in relation to the high number of cases of coinfection with Human Immunodeficiency Virus and patients with evolution to death, assisting the development and implementation of campaigns or projects aimed at early diagnosis and treatment.

Intestinal parasites are a major public health problem. It is important to inform and educate the public about these infections, especially where such data are scarce. This study aimed to determine the prevalence of intestinal parasites from the analysis of medical records of individuals of the city of Londrina. We analyzed 11,641 fecal reports from February 2009 to December 2012. Data were cataloged after the completion of parasitological testing of Hoffmann, Pons & Janer, Faust and Kato-Katz. From 11,641 reports, 19.1% were positive for intestinal parasites. Among those, 52.1% pertained to females and 47.9% to males, with predominance of positivity of 27.1% among children 0-10 years. For the regions studied, the northern region stood out with 35.4% of cases and prevalence of 6.8%. Among the pathogenic protozoa, reports of Giardia lamblia comprised 19.1% of positivity, while hookworms were the most frequent among helminths, comprising 7.8% of positive cases. It follows that poor conditions of basic sanitation contribute to the dissemination of these parasites. Early diagnosis is a determinant of successful treatment. Additionally, epidemiological data may be used to study the risk factors for transmission and may result in measures applicable to improving living conditions in the community

O objetivo deste trabalho foi determinar a presença de parasitas intestinais em amostras de alfaces e almeirões comercializadas em feira livre e supermercado da cidade de Londrina, Paraná. Foram coletadas e analisadas oito amostras de alface (Lactuca sativa) e oito amostras de almeirão (Cichirium intybus). A análise foi realizada no Laboratório de Extensão e Pesquisas em Enteroparasitoses L.E.P.En. Foram encontrados cistos de Endolimax nana, Entamoeba coli, Entamoeba histolytica, Balantidium coli, larvas de Strongyloides stercoralis, larvas e ovos de Ancilostomídeos e ovos de Ascaris spp. Esses resultados demonstram a necessidade de medidas higiênico-sanitárias, visando à educação da comunidade, possibilitando a melhoria na condição de vida da população.
The objective of this study was to determine the presence of intestinal parasites in samples of lettuce andchicory sold in street market and supermarket Londrina city, Paraná. For this purpose, eight samples of lettuce (Lactuca sativa) and eight samples of chicory (Cichorium intybus) were collected and analyzed. The analysis was performed at the Laboratory for Extension and Research in Enteroparasitosis L.E.P.En. Cysts of Endolimax nana, Entamoeba coli, Entamoeba histolytica, Balantidium coli and Strongyloides stercoralis larvae, Hookworm larvae and eggs, and eggs of Ascaris spp were found in the samples.

A Dietilnitrosamina (DEN), uma substância reconhecidamente hepatotóxica e carcinogênica, foiutilizada na indução da necrose hepática centrolobular em ratos isogênicos Lewis divididos em 5 grupos de 5 animais. O objetivo deste estudo foi avaliar o efeito quimiopreventivo da epigalocatequina-3-galato (EGCG), de Camellia sinensis (chá verde) no tratamento da hepatotoxicidade celular induzida pela DEN. Foi mensurada a concentração sérica da alanina aminotransferase (ALT) e aspartato aminotransferase(AST) dos diferentes grupos experimentais. No ensaio bioquímico para AST e ALT, houve diferença significativa entre os valores médios do grupo controle (163±70,32) comparado ao grupo DEN (1631±1039,44), sugerindo que a DEN influencia na função hepática. Entretanto, não houve diferença significativa entre o grupo DEN e o tratado com epigalocatequina. A lactato desidrogenase (LDH) éconsiderada um marcador bioquímico comum para avaliação da progressão tumoral, e em relação ao LDH, as amostras não apresentaram diferenças significativas entre o grupo DEN (1385,5±43,13) e DEN + EGCG 150mg ou DEN + EGCG 200mg 1537,5±1010,45). Neste trabalho foi demonstrado que a epigalocatequina nas concentrações de 150 e 200 mg/Kg não induziram alterações hepáticas e também não foi possível verificar nenhuma quimioproteção pela EGCG em animais inicialmente tratados comDEN durante 24 horas. Sendo assim, novos experimentos com diferentes concentrações de EGCG sãonecessários para comprovar seu possível efeito quimioprotetor.
Diethylnitrosamine (DEN), a known hepatotoxic and carcinogenic substance, was used in the induction of centrilobular hepatic necrosis in isogenic Lewis rats divided into 5 groups with 5 animals. The aim of this study was to evaluate the chemopreventive effect of epigallocatechin-3-gallate (EGCG)from Camellia sinensis (green tea) in the treatment of cellular hepatotoxicity induced by DEN. It was measured the serum concentration of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) of the different experimental groups. In the biochemistry assay for AST and ALT, there was significant difference between median values of control group (163±70.32) compared to DEN group(1631±1039.44), suggesting that DEN influences on hepatic function. However, there was no significant difference between DEN group to that treated with epigallocatechin. Lactate dehydrogenase (LDH) is considered a common biochemical marker for evaluation of tumor progression, and regarding LDH,the samples presented no significant differences between the DEN group (1385.5±43.13) and DEN + EGCG 150mg or DEN + EGCG 200mg (1537.5± 1010.45). In this work it was demonstrated that epigallocatechin concentrations of 150 and 200 mg/kg did not induce liver alterations and though was not verified any chemoprotective effect by EGCG in animals initially treated with DEN for 24 hours. Moreover, new experiments with different concentrations of EGCG are needed to verify its possiblechemoprotector effect.

In the present study, nasal mucus from patients with leprosy were analyzed by PCR using specific primers for Lsr2 gene of Mycobacterium leprae. The presence of Lsr2 gene in the nasal mucus was detected in 25.80% of patients with paucibacillari leprosy, and 23.07% of contacts. Despite the absence of clinical features in the contact individuals, it was possible to detect the presence of Lsr2 gene in the nasal mucus of these individuals. Therefore, PCR detection of M. leprae targeting Lsr2 gene using nasal mucus samples could contribute to early diagnosis of leprosy.
