ABSTRACT

Pemphigus vulgaris is an autoimmune bullous disease whose therapy is based on systemic corticosteroids, with or without immunosuppressants. Rituximab is a chimeric monoclonal antibody of the IgG class, directed at a specific CD20 B cell surface antigen, used in pemphigus vulgaris empirically since 2002, with success in 90% of the cases and long periods of remission. Male patient, 33 years old, diagnosed with pemphigus vulgaris, confirmed by histopathology and direct immunofluorescence. He was treated for seven months with numerous treatments, including immunosuppressive drugs, with an unsatisfactory response, until he had complete remission with the use of rituximab. During a 34-month follow-up period, the patient presented a slight clinical relapse, which was successfully controlled with prednisone in a daily dose of 120mg, soon reduced to 20mg.


Pênfigo Vulgar é uma doença bolhosa auto-imune, cuja terapêutica é baseada em corticoesteróides sistêmicos, associados ou não a imunossupressores. Rituximabe é um anticorpo monoclonal quimérico da classe IgG direcionado a um antígeno CD20 de superfície celular específico da célula B, usado em pênfigo vulgar desde 2002, com sucesso em 90% e longos períodos de remissão. Paciente masculino, 33 anos, diagnóstico de pênfigo vulgar, confirmado por histopatologia e imunofluorescência direta. Durante 7 meses, recebeu inúmeros tratamentos com imunossupressores, apresentando resposta insatisfatória e progressão da doença, até que logo após a introdução de rituximabe teve completa remissão. Durante um acompanhamento de 34 meses, apresentou leve recidiva clínica, controlada com prednisona 120mg/dia, rapidamente reduzida e em uso atual de Prednisona 20mg/dia.

ABSTRACT

CONTEXT: Mucosa-associated lymphoid tissue (MALT) lymphomas are most commonly found in the stomach, lungs, orbital soft tissue, salivary glands and thyroid. Involvement of the trachea is extremely rare. CASE REPORT: This report describes a rare case of MALT lymphoma of the trachea in a 71-year-old woman who presented with a one-year history of coughing, dyspnea, hoarseness and weight loss. There was an infiltrative lesion in the mid-trachea. The anatomopathological diagnosis was only made from the fifth endoscopic biopsy attempt. Immunochemotherapy consisting of rituximab, cyclophosphamide, vincristine and prednisone (R-COP) induced complete remission of the symptoms and endoscopic lesion. CONCLUSIONS: MALT lymphoma of the trachea is extremely rare and indolent disease. It has to be considered in the differential diagnosis of airway lesions. It is crucial to obtain an anatomopathological diagnosis from a specialized pathologist. Immunochemotherapy with R-COP induced complete remission of the disease.


CONTEXTO: Linfomas de tecido linfoide associado à mucosa (TLAM) são mais comumente encontrados no estômago, pulmões, órbita, glandulas salivares e tireoide. O envolvimento da traqueia é extremamente raro. RELATO DE CASO: Relato de caso raro de linfoma TLAM de traqueia, em mulher de 71 anos com tosse, dispneia, rouquidão e emagrecimento há um ano. Detectou-se lesão infiltrativa na porção média da traquéia. O diagnóstico anatomopatológico só foi obtido na biópsia do quinto procedimento endoscópico. A imunoquimioterapia R-COP (rituximabe, ciclofosfamida, vincristina e prednisona) induziu remissão completa dos sintomas e da lesão endoscópica. CONCLUSÕES: Linfoma TLAM de traqueia é uma doença indolente e extremamente rara, que deve ser considerada no diagnóstico diferencial das lesões de vias aéreas. O diagnóstico anatomopatológico por um patologista experimentado é fundamental. Imunoquimioterapia com R-COP levou à remissão completa da doença.

ABSTRACT

CONTEXT: DRESS syndrome (Drug Rash with Eosinophilia and Systemic Symptoms) is a type of drug reaction commonly mistaken for a viral infection. It must be recognized promptly due to its high morbidity and 10 percent mortality rate. Few cases of DRESS syndrome induced by sulfasalazine have been reported in the literature. CASE REPORT: The case of a 47-year-old white Brazilian woman who developed DRESS syndrome eight weeks after starting a course of sulfasalazine for treatment of seronegative arthritis is reported. She presented a skin rash, fever, hepatitis, lymphadenopathy, eosinophilia and atypical lymphocytes. The causative drug was discontinued immediately, but she only improved after treatment with prednisone.


CONTEXTO: A síndrome DRESS (Drug Rash with Eosinophilia and Systemic Symptoms) é um tipo de reação a drogas comumente confundida com uma infecção viral. Deve ser prontamente reconhecida devido a sua alta morbidade e taxa de mortalidade de 10 por cento. Poucos casos de síndrome DRESS induzida por sulfasalazina foram relatados na literatura. RELATO DE CASO: É relatado o caso de uma mulher branca, brasileira, de 47 anos, que desenvolveu a síndrome DRESS oito semanas após iniciar tratamento com sulfasalazina para artrite soronegativa. A paciente apresentou rash maculopapular, febre, hepatite, linfadenomegalia, eosinofilia e linfocitose atípica. A medicação foi suspensa imediatamente no início dos sintomas, mas só houve melhora clínica após tratamento com prednisona.

ABSTRACT

Apesar de resultados discordantes, evidências sugerem que baixas concentrações de colesteroi podem estar associadas a uma variedade de traços de personalidade e atitudes potencialmente relevantes à associação com mortes violentas. Caso comprova- da uma relação d e causalidade nesta associação, a preocupação com as alterações comportamentais, particularmente o aumento de eventos violentos, deve passar a figurar na análise do risco-benefício para a redução do colesterol, sobretudo na prevenção primária da doença cardiovascular em indivíduos com fatores de risco para doença psiquiátrica ou violência. As intervenções para redução do colesteroi em larga escala podem levar a um desvio do comportamento de toda a população para um padrão mais violento. Por outro lado, se este receio for infundado, não deve prejudicar os programas de prevenção da doença cardiovascular já instituídos em várias regiões do planeta. Este artigo traz uma revisão da literatura relativa a baixas concentrações de colesterol, incluindo dados epidemiológicos, estudos de mortalidade global e mortes por violência, além de discutir possíveis mecanismos que justifiquem a associação entre violência e baixo colesterol.(au)

ABSTRACT

PURPOSE: To evaluate the frequency and the consequences of the co-infection of hepatitis B and C viruses in patients with hepatosplenic schistosomiasis (HSS). METHODS: B and C serologic markers, exposure to risk factors, biochemical assays, upper gastrointestinal endoscopies, and abdominal ultrasonograms were evaluated in 101 patients with HSS from 1994 to 1997. Whenever possible, PCR was tested and histopathological studies were reviewed. RESULTS: At least one HBV virus marker was found in 15.8 percent, and anti-HCV was detected in 12.9 percent of the subjects. The seropositive subjects tended to be older than the seronegative ones. A history of blood transfusion was significantly related to the presence of anti-HCV. Three (18.75 percent) out of 16 subjects exposed to B virus were HBsAg positive. Eleven (84.6 percent) out of thirteen patients who were anti-HCV positive demonstrated viral activity. Patients with ongoing viral infection presented a higher average level of liver aminotransferases, a higher frequency of cell decompensation and a higher rate of chronic hepatitis. Portal hypertension parameters were not influenced by viral exposure. CONCLUSIONS: The rate of hepatitis B and C viruses serologic markers observed in the patients with HSS was higher than the control group. The co-infection was responsible for a higher frequency of cell decompensation

ABSTRACT

CONTEXT: Oncocytomas are generally small and present slow growth. Finding of the tumor usually occurs incidentally. Their incidence is higher among male patients. Oncocytomas in mucous bronchial glands are extremely rare. CASE REPORT: A 35-year-old male who presented bronchial oncocytoma. The tumor was found after bronchoscopy that investigated an atelectasis of the upper left lobe. Histological examination with optical microscopy revealed a mature neoplasm formed by ovoid cells with thin, granular, eosinophilic cytoplasm and small nuclei similar to oncocytes. Electron microscopy showed mitochondrial hyperplasia. A three-year follow-up after thoracotomy followed by lobectomy and removal of the bronchial tumor was uneventful
