Introduction Gout is an illness characterized by the deposition of monosodium urate crystals in the joints or in soft tissues. The clinical manifestation results from inflammation of limb joints and pain with a rare presentation in the temporomandibular joint (TMJ). Case Report This study describes a 66-year-old white man with a chief complaint of “occasional pain in the left temporal muscle region.” The case disclosed a gout manifestation in the TMJ after physical, radiographic, and ultrasonographic exams, and the patient was referred to proper treatment. Conclusion Gout manifestation in the TMJ is an unusual presentation, and few reports in the English literature address to the subject. Gout in the TMJ should be included as a differential diagnosis for joint disorders.
Saturnism is the poisoning that occurs in activities with high occupational exposure to lead (Pb). Although less common, poisoning can occur after incidents with firearm projectiles (FAP). The present study describes a clinical-surgical case of saturnism by FAP accident in a male patient exposed to multiple fragments and blood lead limiting levels. His main complaint in a maxillofacial consultation was "lead in the body". After several surgeries and controls between 2007 and 2011, the patient had decreased blood lead levels from 44 mcg/dL to 15.6 mcg/dL and improvement in urinary tract infections, depressions, and mood changes. Saturnism should be included in the diagnostic investigation of patients wounded by gunshots. The proper poisoning diagnosis certainly will assist in the appropriate intervention.

Introdução: A terapia biológica revolucionou o tratamento das doenças inflamatórias intestinais (DII). Embora muito efetivas, as medicações biológicas colocam os pacientes em maior risco de desenvolvimento de reações infusionais e paradoxais, infecções e alguns tipos de câncer como linfomas, este último especialmente quando feita em combinação com tiopurinas. A adequada seleção, aconselhamento e educação dos pacientes são itens importantes para o uso bem sucedido dos biológicos. Objetivo: Revisar a melhor estratégia para mostrar uma visão atualizada das etapas imprescindíveis no preparo dos pacientes com DII para terapia biológica. Material e Métodos: Realizou-se uma revisão sistemática da literatura, em fevereiro de 2018, utilizando os termos de pesquisa: “doença de Crohn”, “doença inflamatória intestinal”, “imunização”, “imunossupressores” e “terapia biológica”, em língua inglesa e portuguesa. Foram incluídos apenas artigos originais e de revisão. Discussão e Conclusão: Uma história detalhada para excluir contraindicações destas medicações e um monitoramento baseado em diretrizes são passos importantes antes de iniciar a terapia. Biológicos devem ser considerados somente se uma avaliação confirmar que o paciente tem doença ativa. É relevante também excluir condições que mimetizam a atividade de doença. Até o momento, os agentes biológicos demonstraram um perfil de segurança favorável em pacientes com DII. No entanto, é importante que o início da terapia biológica seja discutido atentamente com os pacientes, explicando os riscos e benefícios do tratamento. Antes de iniciar o uso de biológicos, os pacientes necessitam ser rastreados para tuberculose latente, hepatites B e C, e infecção por HIV. Idealmente, o status vacinal deve ser verificado e atualizado antes do início da terapia imunossupressora. As diretrizes atuais recomendam aos pacientes adultos com DII o mesmo esquema de imunização de rotina da população geral, evitando as vacinas de agentes vivos durante a terapia imunossupressora. Todas essas medidas são essenciais para estabelecer de forma segura a terapia esperada pelo uso de biológicos.
Solid pseudopapillary neoplasms (SPN) are rare and represent a minority of all pancreatic cystic tumors. Symptoms, if present, are generally nonspecific and upper gastrointestinal bleeding is extremely uncommon as an initial presentation. A 31-year-old woman with no prior medical history presented with a 3-week period of epigastric pain, which she reported as persistent, exacerbated by eating, and associated with progressive asthenia, fatigue, and exertional dyspnea. One month prior, she had had experienced 2 episodes of melena. Upon physical examination her skin was pale, with no other changes. Through diagnostic investigation, an esophagogastroduodenoscopy showed a giant ulcer in the duodenal bulb and a suspect fistulous orifice localized on the posterior wall of the duodenal bulb. In addition, a bulge on the duodenal bulb, suggestive of an extrinsic compression, was noticed. An abdominal computed tomography scan and magnetic resonance imaging showed a mixed solid and cystic lesion in the head of the pancreas in direct proximity to the duodenum, which contained an image compatible with a fistula. The patient successfully underwent pancreaticoduodenectomy. The histopathology, including microscopic analysis and immunohistochemistry, was consistent with an SPN of the pancreas. This case emphasizes that the evaluation of patients presenting with upper gastrointestinal bleeding due to a giant duodenal ulcer and an extrinsic mass effect noted on the duodenum should include cross-sectional images of the abdomen. In this case, the finding of a large well-encapsulated pancreatic solid and cystic mass on abdominal images was suggestive of a pancreatic neoplasm diagnosis, including an SPN.
