Hiperplasia nodular focal do fígado: apresentação de um caso e revisão da literatura

Neste trabalho apresentamos um caso de hiperplasia nodular focal que foi diagnosticado aos seis anos de idade e que está sendo acompanhado até o momento presente. Para o diagnóstico foram imprescindíveis as técnicas de imagem, tendo importância de realce a cintilografia hepatoesplênica e a tomografia computadorizada. Apresentamos, também, revisão da literatura sobre o assunto.

Reativação da retocolite ulcerativa com o uso de droga anti-inflamatória não esteróide: relato de caso e revisão da literatura

The case of a patient with ulcerative colitis and isolated sacro-ileitis is presented. She suffered reactivation of the intestinal disease with diclofenac. The patient was allergic to sulfasalazine and was using fish oil fatty acid. The possible mechanisms of reactivation of the inflammatory bowel disease with non-steroidal anti-inflammatory drugs are discussed. It is suggested when necessary the utilization of non-steroidal anti-inflammatory drugs that inhibits the lipoxygenase in these patients.

Utilização do metabolismo protéico ( 15N-glicina) na detecção precoce de agravamento da atividade da doença em pacientes portadores de retocolite ulcerativa inespecífica

Disease activity was assessed in 10 (five males and five females) ulcerative colitis patients through the following parameters: clinical, laboratory, sigmoidoscopic and histological. Protein metabolism was also assessed with 15N-glycine and urinary ammonia as end product. Only one patient had exacerbation of the disease two months after the study started. This patient presented in the beginning of the study protein synthesis and breakdown of 4.51 and 3.47 g protein/kg/day, respectively, values higher than all other patients, showing an hypermetabolic state, suggesting an increase of the disease activity. However, this increase was not detected by others indicators and indexes utilised. These data allow to suggest the hypothesis that protein metabolism predicts precociously the exacerbation of disease activity in ulcerative colitis patients.

Infliximabe no tratamento inicial da retocolite ulcerativa moderada e grave. Terapia top down: Relato preliminar

The first option for the treatment of UC is both: salicylates or corticoids. Recently, in late November of 2006, the Brazilian Ministry of Health has approved infliximab (Remicade c, Mantecorp, Brazil) to treat ulcerative colitis. We report the use of infliximab as a first option for the treatment of two patients with severe ulcerative colitis. Case report: Patient 1: AZF, 52 years-old, female, was first diagnosed with UC after history and clinical examination; colonoscopy showed pancolitis with positive biopsy (crypt microabscess). Her Mayo score was 10 (range: 0 to 12/asymptomatic to severe colitis). She received intra venous infusion of infliximab at a dose of 5mg/Kg of body weigh at week 0, 2, 6 and 14. Then, patient was given mesalazine 4.5 g/day for maintenance therapy. Clinical response was defined as a decreased from baseline in the total Mayo score of at least 3 points. At present, patient is asymptomatic with Mayo score of 3 one moth after the last dose of infliximab. Patient 2: MLA, 45 years-old, female was first diagnosed with bloody diarrhea; colonoscopy showed left colitis and the biopsy was positive for ulcerative colitis. Her Mayo score was 9. She was offered and accepted the step down treatment. She was given infliximab 5mg/Kg of body weight at week 0, 2, 6 and 14. After initial treatment with infliximab, she received mesalazine 4.2 g/day. At present, she is asymptomatic with Mayo score of 2 eighteen days after the last dose of infliximab. At our knowledge, this is the first Brazilian report of the use of infliximab as fist-line therapy in ulcerative colitis. Few days after the begging of the infusion, an impressive clinical and colonoscopy improvement was seen in these two patients. Recently, it has been reported the use of infliximab as first-line therapy in pediatric Crohn disease. Infliximab could be a good option in cases of moderate and severe UC to avoid the side effects of the use of high doses of corticoids in patients with moderate and severe UC. However, the question if step-down therapy in ulcerative colitis is better then conventional therapy with salicylates and corticoids needs to be answered by randomized trials.

Nodular dermatofibrosis in a gentian shepherd dog: case report

An 7-year-old male German shepherd dog not neutered was attended presenting several cutaneous nodules ranging from 0.5-3 cm in diameter at least a one year history, located mainly in thoracic and pelvic limbs, with progressive weight loss over two months. Fine needle aspiration biopsy and pelvic and thoracic limbs nodules excision biopsy were performed. After histopathological diagnosis, nodular dermatofibrosis diagnosis was determined and abdominal ultrasound was performed for possible renal cysts evaluation. The animal received treatment to control secondary bacterial infection. It is necessary to carry out histopathological examination and ultraosund to identify possible renal cysts and for definitive diagnosis. There is no specific treatment for nodular dermatofibrosis. © 2013 Asian Network for Scientific Information.
