Study of the histopathological types of cutaneous melanoma in Palmas-TO from 2001 to 2011

AbstractBACKGROUND:Cutaneous melanoma (CM) is considered serious for causing frequent metastasis, presenting high mortality, resistance to available therapies and incidences in laboring activity.OBJECTIVES:To study the histopathological types of cutaneous melanoma in Palmas-TO from 2001 to 2011, according to risk factors, location of lesions, Clark levels and Breslow thickness.METHODS:A descriptive, retrospective and quantitative research in reports of the Serviços de Anatomia Patológica in Palmas (SAPP) and Registro de Câncer de Base Populacional de Palmas (RCBPP).RESULTS:The years of highest incidences were: 2004 (8 cases/17.8%), 2008 and 2011 (7 cases each/15.6%) and 2010 (6 cases/13.3%). Among the 45 cases studied, there were predominance in patients between 41 and 60 years old, women, caucasians, farmers, located in trunk, in situ type, superficial extensive and metastatic cutaneous, Clark levels I (20%) and IV (17.7%), Breslow thickness ≤1 mm (35.5%) and 2.01 to 4 mm (24.4%).CONCLUSIONS:The most common histopathological types were: cutaneous melanoma in situ, superficial extensive and metastatic, followed by nodular cutaneous melanoma, and finally, by other forms. In this study, Clark levels and Breslow thickness pointed to greater importance of thin melanomas and sun exposure without appropriate protection in farmers.

HIV/AIDS-related visceral leishmaniasis: a clinical and epidemiological description of visceral leishmaniasis in northern Brazil

Introduction: This study aimed to describe the main features of visceral leishmaniasis (VL), both related to and independent of human immunodeficiency virus (HIV) infection, in patients who were registered in Tocantins, Brazil. Methods: Data from 1,779 new patients with VL, 33 of whom were also infected with HIV, were reviewed. Results: The incidence of VL/HIV coinfection increased from 0.32/100,000 inhabitants in 2007 to 1.08/100,000 inhabitants in 2010. VL occurred predominantly in children aged 10 years or younger, while VL/HIV was more common in patients aged between 18 and 50 years. There were more male patients in the VL/HIV group than in the VL group. Relapse rates were also considerably higher in the VL/HIV (9.1%) group than in the VL group (1.5%). Despite a similar clinical presentation, VL/HIV patients exhibited a higher proportion (24.2%) of concomitant infectious diseases and jaundice. Pentavalent antimonials were used for the initial treatment of VL and VL/HIV infections. However, amphotericin B deoxycholate and liposomal amphotericin B were also widely used in the treatment of VL/HIV coinfection. The mortality rate was higher in the VL/HIV coinfection group (19.4%) than in the VL group (5.4%). Furthermore, the mortality rate due to other causes was significantly higher in the VL/HIV group (12.9%) than in the VL group (0.7%). Conclusions: The study showed that the incidence, clinical characteristics and outcomes among the VL and VL/HIV patients in this state are similar to those from other endemic regions, indicating that both infections are emerging with increasing frequency in Brazil. .

Prevalência de sepse e fatores de risco em neonatos de unidade de terapia intensiva de referência em Palmas,Tocantins, Brasil / Prevalence of sepsis and risk factors in newborns from intensive care unit of reference in Palmas, Tocantins, Brasil

As infecções microbianas neonatais, especialmente as sepses, correspondem a uma das causas mais importantes de morbimortalidade em unidades de terapia intensiva e sua prevalência é maior naqueles pacientes expostos a procedimentos invasivos. Objetivo: identificar a prevalência de sepse neonatal hospitalar, bem como os principais fatores de risco associados a esta infecção e os microrganismos envolvidos. Métodos: foi realizado um estudo retrospectivo revisando as fichas de investigação epidemiológica do Serviço de Controle de Infecção Hospitalar com dados dos recém-nascidos internados em unidade de terapia intensiva de referência estadual do Tocantins, no período de julho de 2007 a junho de 2009. Observou-se que 25% dos pacientes analisados desenvolveram sepse neste período, dos quais 60% foram do gênero masculino, 67% prematuros e 65% com peso ao nascer menor que 2500 gramas. Entre os fatores de risco de importância clínica, observou-se a prematuridade, baixo peso ao nascimento, ventilação mecânica, cateterismo venoso central e utilização de nutrição parenteral. A prematuridade e o peso ao nascimento foram fatores de menor risco relativo quando comparados aos demais fatores analisados. Resultados: foram identificados 111 pacientes com sepse, com taxa de mortalidade de 26%. Os principais microrganismos associados à sepse neonatal foram Klebsiella pneumoniae (28%), os Staphylococcus coagulase negativa - CoSN (20%) e Candida albicans (14%). Conclusão: os achados neste estudo reforçam a importância de ações de prevenção de infecções neonatais, bem como o manejo asséptico durante a instalação e a manutenção de procedimentos invasivos necessários aos cuidados intensivos neonatais

Neonatal bacterial infections, especially sepsis, are one of the most important causes of morbidity and mortality in intensive care units and they are more prevalent among patients who have undergone invasive procedures. Objective: to identify the prevalence of hospital neonatal sepsis as well as the associated risks factors for this infection and the involved microorganisms. Method: a retrospective study was done going over the epidemiological investigation forms of the Service of Hospital Infection Control with data from newborns admitted in a State reference intensive care unit in Tocantins, from July 2007 to June 2009. We noticed that 25% of the analyzed patients developed sepsis and 60% were males, 67% premature and 65% with a weight at birth below 2500 grams. Among the risks factors of clinical importance we noticed, the prematurity, low birth weight, mechanical ventilation, central venous catheterization and use of parenteral nutrition. The prematurity and birth weight were lower relative risks factors in comparison with the other analyzed factors. Results: 111 patients with sepsis were found, with a mortality rate of 26%. The main microorganisms associated with neonatal sepsis were Klebsiella pneumoniae (28%), Staphylococcus coagulase negative - CoSN (20%) and Candida albicans (14%). Conclusion: the findings on this study emphasize the importance of actions for prevention of neonatal infections as well as aseptic handling during set up and maintenance of invasive procedures needed in neonatal intensive care
