Condiloma lingual: a case report

O condiloma acuminado é uma doença sexualmente transmissível causada pelo Papilomavírus humano (HPV). Freqüente na região anogenital e rara na cavidade oral. No entanto, o aumento da atividade oro-sexual vem cada vez mais favorecendo a instalação da infecção do HPV na mucosa oral. O presente relato descreve um condiloma na cavidade oral em um paciente do sexo masculino, de 35 anos, com história de prática de sexo oral, cujo diagnóstico foi confirmado pela biópsia. O tratamento instituído foi efetuado com o uso de ácido tricloacético a 80%, ocorrendo remoção completa da lesão. Foi feito uma revisão da literatura acerca da incidência, quadro clínico, diagnóstico, tratamento e profilaxia.

A model of destination competitiveness/sustainability: Brazilian perspectives

This paper reviews the understanding I have gained from several years of research, and from several more years of ongoing discussions with industry leaders regarding the nature of competitiveness among tourism destinations. This understanding has been captured, in summary form, in the model of Destination Competitiveness/Sustainability (Ritchie and Crouch, 2003). This model contains seven (7) components which we have found to play a major role, from a policy perspective, in determining the competitiveness/sustainability of a tourism destination. In addition to the valuable understanding which these seven components provide from a policy perspective, the specific elements of each the major components provide a more useful/practical guidance to those who are responsible for the ongoing management of a DMO (Destination Management Organization). With this overview in mind, this paper will provide a detailed review and explanation of the model that I have developed with colleague, Dr. Geoffrey I. Crouch of Latrobe University in Melbourne, Australia. Based on previous presentations throughout the world, it has proven very helpful to both academics and practitioners who seek to understand the complex nature of tourism destination competitiveness/sustainability.

Anti-leishmania igA immunoenzymatic assay in mucocutaneous leishmaniasis (Preliminary report)

The Authors describe an anti-Leishmania IgA-ELISA assay in mucocutaneous leishmaniasis. Increased titers were found in leishmaniasis patients, mainly in the first and second year of infection and in deep mycoses patients showing either mucosal involvement or widespread disease.

Cardiac involvement in human rabies: case report

A case of human rabies with cardiac involvement and viral inclusion bodies in the heart is presented. The Negri bodies were found in the Schwann cells of the right epicardial atrium, with secondary mononuclear cells inflammation. In the myocardium, an interstitial edema, proliferation of Anitschkov and rare mononuclear inflammatory cells were seen. There was no relevant cardiovascular signs or symptoms. The rarity of histological descriptions of Negri bodies in the heart is stressed, as well as the importance of cardiac involvement as a potential complication for cases with life prolonged by intensive care units, or in the end-stages of the disease.

Acute Hepatitis B in a patient previously positive for antibody to surface antigen (anti-HBs) determined by radioimmunoassay: case report and review of the literature

The determination of anti-HBs as a screening test before vaccination has been advisable in order to encounter immune individuals that don't need to receive vaccine protection. A case-report is presented and three other cases are reviewed from the literature. Anti-HBs was positive in these health-care personnels that developped typical acute B hepatitis. Different subtyping involving the d/y determinants were found in the first case, but false-positive anti-HBs even with high titres, determined by RIA, were found in the other cases. Concomitant determination of anti-HBc or absence of screening tests seem to be more reasonable policies until a low-cost and risk-free vaccine is produced.

Acute myocardial infarction in chronic Chagas' cardiomyopathy: report of two cases with no obstructive coronary artery lesions

This report describes two patients with chronic Chagas' Heart Disease who developed clinical and laboratorial signs of myocardial infarction. Both patients presented sudden oppressive chest pain, without precipitating factor. In the first case, the highest MB-CK value was 65 IU, 22 hours after the beginning of the pain. On the second case, it was 77 IU at 18 hours after the beginning of the pain. In both cases ECG changes suggesting non-transmural infarction were present. The 99mTc PYP myocardial scintigram of the first case was positive. Coronary angiograms performed on the 18th and 9th day, respectively, after the acute infarction did not display obstructive lesions. Possible mechanisms causing myocardial infarction with normal coronary arteries in Chagas' Disease may include: embolic event's, particularly when there is associated congestive heart failure; coronary thrombosis and coronary spasms.

Acute diarrhoea associated with Cryptosporidium sp in Belém, Brazil (preliminary report)

Cryptosporidium sp was detected in faeces from three children suffering from acute diarrhoea. In two cases no other concomitant agents were detected and in a 3rd. this agent was associated with Entamoeba histolytic, Entamoeba coli, Endolimax nana, Chilomastix mesnili and Pentatricbomonas hominis.

Human disease in ribeira valley, brazil caused by caraparu, a group c arbovirus - Report of a case

The clinical and laboratory data of a disease in a resident of Ribeira Valley, São Paulo State, southeastern Brazil, caused by an agent close or identical to Caraparu, a Group C arbovirus, was described. Although there is evidence of an intensive circulation of several arboviruses in the area, no diagnosis of human disease by these agents has been made, except the encephalitis cases caused by Rocio virus during an epidemic in 1975-1977. An antigenic difference between Caraparu strains isolated in São Paulo and in Pará States and a close antigenic relationship between Caraparu strain from São Paulo and Bruconha virus were suggested by the serological tests.

Seizures and Praziquantel. A case report

A 27 year Old male developed seizures after receiving a single 20 mg/kg dose of praziquantel for the treatment of an intestinal Hymenolepis nana infection. On further clinical and laboratorial evaluations, he was found to suffer from an until then asymptomatic parenchymal brain cysticercosis. Praziquantel must be used with caution in those areas where cysticercosis represents a mayor public health problem. The occurrence of unexpected seizures in an individual being treated with the compound, must prompt clinicians to rule out cysticercosis of the CNS.

Chagas' Disease: an acute transfusional case report

Report of a case of acute transfusional Chagas'disease in a four-year-old child with a previous diagnosis of acute lymphocytic leukemia, transmitted in São Paulo, the Capital of São Paulo State, Brazil. Epidemiological investigation disclosed the donor's serological positivity and his previous residence in an area where Chagas' disease is endemic. The importance of adequate sorological screening in blood donors is evident. It should be stressed that this is the first case notified to the Superintendência de Controle de Endemias (SUCEN) (Superintendency for the Endemy Control) of the State Secretariat of Health, São Paulo, for the last five years.
