ABSTRACT
BACKGROUND AND AIMS: Submucosal injection of a viscoelastic solution prolongs submucosal lift, thus, facilitating endoscopic mucosal resection. Our objective was to assess the safety and clinical effectiveness of 0.4% hydroxypropyl methylcellulose (HPMC) as a submucosal injectant for endoscopic mucosal resection. PATIENTS AND METHODS: A prospective, open-label, multicenter, phase 2 study was conducted at 2 academic institutions in Brazil. Eligible participants included patients with early gastrointestinal tumors larger than 10 mm. Outcomes evaluated included complete resection rates, volume of HPMC injected, duration of the submucosal cushion as assessed visually, histology of the resected leisons, and complication rates. RESULTS: Over a 12-month period, 36 eligible patients with superficial neoplastic lesions (stomach 14, colon 11, rectum 5, esophagus 3, duodenum 3) were prospectively enrolled in the study. The mean size of the resected specimen was 20.4 mm (10 to 60 mm). The mean volume of 0.4% HPMC injected was 10.7 mL (range 4 to 35 mL). The mean duration of the submucosal fluid cushion was 27 minutes (range 9 to 70 min). Complete resection was successfully completed in 89%. Five patients (14%) developed immediate bleeding requiring endoclip and APC application. Esophageal perforation occurred in 1 patient requiring surgical intervention. There were no local or systemic adverse events related to HPMC use over the follow-up period (mean 2.2 mo). CONCLUSION: HPMC solution (0.4%) provides an effective submucosal fluid cushion and is safe for endoscopic resection of early gastrointestinal neoplastic lesions.

A escleroterapia endoscópica é uma modalidade de tratamento efetiva no controle do sangramento agudo e na prevenção do ressangramento de varizes esofagianas. No entanto, é associada a complicações significativas, tais como hemorragia, estenose e perfuração de esôfago. Relata se caso de paciente que apresentava varizes esofagianas de fino calibre e foi submetido à escleroterapia endoscópica com pequeno volume de oleato de etanolamina. O paciente evoluiu com disfagia total em 12 horas devido a volumoso hematoma submucoso do esôfago. Foi adotado tratamento conservador (jejum, hidratação venosa e antibioticoterapia) com êxito. Endoscopia digestiva alta (EDA) realizada após seis semanas e seis meses mostrou resolução completa do hematoma, retrações cicatriciais e ausência de varizes. O hematoma submucoso esofagiano é complicação grave da escleroterapia endoscópica e pode ocorrer mesmo após aplicação de pequeno volume de esclerosante em varizes de fino calibre. O tratamento indicado é conservador e consiste em suporte clínico, jejum, hidratação venosa e antibióticos...

É relatado o caso clínico de paciente adulto com febre de origem inderteminada e perda de peso inexplicável, procedente de área urbana que recentemente se tornou foco da Leishmania Donovani. A urbanização da leishmaniose não é só um alerta quanto ao descuido sanitário, mas revela o poder de adaptação da vida e da necessidade de se buscar na epidemiologia o apoio ao diagnóstico clínico. Enfatiza-se 0 cuidado permanente com o uso de anfotericina B.
The clinical case of adult patient with fever of unknown origin and inexplicable weight loss is described. The patient lived in urban area that, recently, became a focus Leishmania Donovani. The urbanization of leishmaniasis is a sign of sanitary carelessness and shows the power of adaptation of a living organism. There is a need of the support of an epidemiologist for the clinical diagnosis. The permanent care with the use of anfotericin B should be emphasized.

A leucemia mieloblástica aguda é doença grave, de prognóstico reservado e pequena sobrevida. Reporta-se neste trabalho a associação em uma pessoa entre leucemia mieloblástica aguda e diabetes insipidus, por infiltração leucêmica no sistema nervoso central.
The acute myeloblastic leukemia is a severe disease, marked by an unfavorable prognosis and low survival rates. We report one case of association between acute myeloblastic leukemia and diabetes insipidus caused by infiltration of the central nervous system.
