Abstract: Due to mounting evidences of interaction between Hansen's bacilli with endothelial cells and the paucity of studies addressing the presence of nailfold capillaroscopic alterations in patients with Hansen's disease, a study was carried out in order to verify the presence of capillaroscopic alterations in patients with leprosy in its various forms and its correlation with clinical parameters. Ten patients were evaluated at a specialized university service. Sixty percent of those had some capillaroscopic change, such as micro-hemorrhages, ectatic, bushy and corkscrew capillaries. Such changes were unspecific, which suggests there is not a specific pattern for this disease.

Abstract Background: The incidence of cutaneous melanoma has increased over the last decades. Recurrences occur most frequently within the first 2-3 years after diagnosis but patients carry a lifelong risk of relapse. Nevertheless, there is no consensus in the literature on what screening tests patients should undergo. Objectives: To evaluate the most common melanoma metastasis sites among a South Brazilian population from a city with one of the highest melanoma rates, and establish the best screening method for these patients. Methods: A cross-sectional retrospective study of 108 consecutive melanoma patients followed up at a center from 2009 to 2013. Data were collected on demographic and tumoral characteristics, as well as the site of the first diagnosed metastasis. Results: Patients were divided into 3 groups for analytical purposes: Non-visceral metastases (48% of patients), visceral metastasis (39%) and brain metastasis (13%). We tried to correlate age, gender, mean Breslow thickness, mitosis and death rates with the aforementioned groups but none showed any statistically significant association. Conclusion: Melanoma patients must be monitored to detect early relapse and subsequent effective treatment but the best follow-up strategy remains to be established.

AbstractBACKGROUND:Leprosy is an infectious disease that may lead to irreversible nerve damage, compromising patient's quality of life and leading to loss of working years.OBJECTIVES:To evaluate the epidemiological profile of patients followed at a University Hospital.MATERIALS AND METHODS: This is a retrospective observational study, based on a review of medical records. We studied the clinical and epidemiological features of patients with leprosy monitored at the Hospital de Clínicas of the Federal University of Paraná between January 2005 and January 2010.RESULTS:The mean age was 47.51, while 35.94% of patients were aged 41-60. The male:female rate was 1.8:1. The most prevalent occupations were: retired, students or rural workers. Patients came mainly from Curitiba or nearby areas, but there were also patients from the countryside. The mean diagnostic delay was 24.57 months. Multibacillary forms prevailed, with the lepromatous variety being the most common, closely followed by the borderline type. Neural enlargement was found in more than 50% of the patients and 48.44% of them developed reactional states. Hemolysis was the most commonly detected drug side effect. Initial functional evaluation was possible in 70% of patients, 55% of whom had disabilities upon diagnosis. The most prevalent associated disease was hypertension.CONCLUSIONS:This study showed an important diagnostic delay and a high rate of sequelae in this specific population. Brazil is one of the few remaining countries that has not yet eradicated leprosy and it is important to improve health policies in order to prevent sequelae and achieve eradication.

BACKGROUND: Cutaneous melanoma is a highly aggressive malignancy with increasing incidence worldwide. The southern Brazilian state of Santa Catarina has one of the highest incidence rates of melanoma in the country. OBJECTIVE: To evaluate the epidemiological profile of melanoma patients in a southern city of Brazil. METHODS: a cross-sectional retrospective study was conducted, aiming to detect the clinical and histopathological characteristics of cutaneous melanoma diagnosed in the city of Brusque - SC, between 1999 and 2013. RESULTS: A total of 213 cases in 212 individuals were studied. More than 50% of the patients were females (p< 0.05). The trunk was the most commonly affected site (p< 0.05), followed by the upper limbs. Nodular and superficial spreading melanomas were the most commonly detected in histological analyses. They did not differ statistically in frequency, but were more prevalent than other histopathological subtypes (p< 0.05). There was no statistically significant difference between invasive and noninvasive melanomas (p= 0.2441). Among the invasive melanomas, those with Breslow thicknesses < 1 mm and between 1-2mm were more prevalent (p< 0.05). CONCLUSIONS: In this study we found a higher frequency of melanomas in female patients and patients aged over 51. The trunk was the most commonly affected site. Nodular and superficial spreading melanomas prevailed. Among invasive melanomas, those with Breslow thicknesses < 2 mm were the most frequent. This paper highlights the epidemiological profile of melanoma patients in the city and may help to identify and aid in the follow-up of those who are most likely to present the disease.

Este relato de caso, junto com a revisão de literatura, descreve um paciente com diagnóstico de hepatite viral aguda, que desenvolveu quadro de dor abdominal intensa e alterações laboratoriais compatíveis com pancreatite aguda. Casos de pancreatite aguda complicando hepatites virais agudas fulminantes e não fulminantes tem sido esporadicamente relatados e vários mecanismos são propostos para explicar esta complicação, no entanto sua causa ainda se mantém desconhecida. Como a hepatite aguda é doença comum, é importante estimular o desenvolvimento de mais estudos na América Latina que visem determinar a incidência local e o perfil dos pacientes que apresentam esta complicação.

This case report, along with the review presented, describes a patient diagnosed with acute viral hepatitis, who developed a framework of intense abdominal pain and laboratorial alterations compatible with acute pancreatitis. The association of acute pancreatitis complicating fulminant and non-fulminant acute hepatitis virus (AHV) has been reported and several mechanisms have been proposed for this complication, but so far none is clearly involved. As acute hepatitis is a common disease, it is important to stimulate the development of other studies in order to determine local incidence and profile of patients presenting this association in our environment.

A linfangiomatose, doença rara e de origem controversa, ocorre em indivíduos de todas as faixas etárias, predominando entre os mais jovens, sem predileção por sexo. Comumente cursa com envolvimento torácico, porém órgãos como ossos, baço e fígado podem ser acometidos. Histologicamente, o envolvimento pulmonar cursa com proliferação, anastomoses complexas e dilatação secundária do sistema linfático. Clinicamente, a apresentação é variável. Os achados radiográficos podem ser sugestivos e o diagnóstico é definido pela histologia. Relatamos dois casos da doença; uma das pacientes era oligossintomática e encontra-se em tratamento; na outra, a doença foi mais agressiva e o diagnóstico muito tardio, culminando em óbito.

Lymphangiomatosis, a rare diseases of controversial origin, occurs in individuals of any age, regardless of gender, but is predominantly seen in younger individuals. It often presents with thoracic involvement, although, the bones, spleen and liver can also be affected. Histologically, the pulmonar involvement includes proliferation, complex anastomoses and secondary dilatation of the lymphatic vessels. Clinically, the presentation is variable. Although radiographic findings can be suggestive of the disease, the final diagnosis is made histologically. We report two cases of lymphangiomatosis, both in females: one was oligosymptomatic and is being treated for the disease; the other had a more progressive form, was diagnosed quite late and ultimately died of the disease.
