Leg Ulcers in Antiphospholipid Syndrome Secondary to Systemic Lupus Erythematosus Treated with Intravenous Immunoglobulin

BACKGROUND: Despite encouraging reports on the efficacy of intravenous immunoglobulin (IVIg) in antiphospholipid syndrome, the clinical value of this treatment is not well established, and most of the data are based on case reports and small series of patients. OBSERVATION: We describe the significant improvement of leg ulcers with IVIg in a 61-year-old female, with diabetes mellitus, venous peripherical insufficiency and secondary antiphospholipid syndrome to systemic lupus erythematosus. CONCLUSIONS: This case illustrates a rare cause of leg ulcers and documents that IVIg may be an effective adjuvant treatment in the management of selected patients with antiphospholipid syndrome when conventional strategies using subcutaneous heparin and low-dose aspirin are insufficient.

Mucormicose Naso-Sinusal - Casos Clínicos e Revisão da Literatura

A mucormicose e uma infecção fúngica potencialmente grave,causada por fungo saprófita. Pode tornar-se patogénico, em condições específicas, com evolução frequentemente fatal, particularmente em indivíduos imunocomprometidos. A doença inicia-se com a inalação do fungo para os seios perinasais. 0 fungo pode invadir o palato, os seios perinasais, o seio cavernoso, as órbitas e cavidade craniana. A chave para uma terapêutica de sucesso inclui, a suspeição c1ínica e diagnóstico precoces e a estabilização das comorbilidades, em conjunto com uma terapêutica médica e cirúrgica agressivas. Apresentamos três casos c1ínicos de mucormicose rino-sinusal em doentes imunocomprometidos (sexo masculino), com idade media de 70 anos, com diagnóstico histopatologico de mucormicose, tratados no último ano (2009), no Serviço de Otorrinolaringologia do Hospital de S.José.Todos os doentes foram tratados com anfotericina B lipossómica e dois deles, foram submetidos a desbridamento cirúrgico, o desfecho foi fatal em dois dos doentes. A mucormicose caracteriza-se por um quadro c1ínico grave, que exige um diagnóstico precise e tratamento rápido, já que apresenta mortalidade elevada, não só pelas características da infecção, mas também pelas condições subjacentes aos doentes.

The Role of Propranolol in the Treatment of Infantile Hemangioma

INTRODUCTION: Infantile hemangioma (IH) is one of the most common childhood tumors. There are various medical or surgical therapeutic options, all with suboptimal results. Recently, the successful use of propranolol for involution of IH was described. We report the results of a single-center experience with this therapeutic option. OBJECTIVE: To prospectively assess the efficacy and safety of propranolol in children with infantile hemangioma. METHODS: We performed a prospective analysis of clinical data of all patients with IH referred to a pediatric cardiology center for baseline cardiovascular assessment prior to propranolol therapy. Propranolol was given at a starting dose of 1 mg/kg/day and titrated to a target dose of 2-3 mg/kg/day according to clinical response. Efficacy was assessed through a photograph-based severity scoring scale. Safety was assessed by collecting data regarding significant side effects. RESULTS: Starting in 2010, 30 patients (15 female) were referred for propranolol treatment of IH, at a median age of six months (1-63 months). The mean target propranolol dose was 2.8 mg/kg/day, with a mean duration of therapy of 12 months. All patients experienced significant reduction of IH size and volume. There were no side effects. CONCLUSIONS: In our experience propranolol appears to be a useful and safe treatment option for severe or complicated IH, achieving a rapid and significant reduction in their size. No adverse effects were observed, although until larger clinical trials are completed, potential adverse events should be borne in mind and consultation with local specialists is recommended prior to initiating treatment.

Methadone Intoxication in a Child: Toxic Encephalopathy?

Methadone is used in the treatment of opioid addiction. Acute intoxication can lead to severe consequences and can even be lethal. In several case reports and small series, a presumably toxic leukoencephalopathy is described resulting from inhalation of heroin. We present the case of a 3-year-old boy who ingested methadone accidentally. In a coma with acute obstructive hydrocephalus owing to massive cerebellar edema and supratentorial lesions, he was successfully treated with methylprednisolone and cerebrospinal fluid external drainage. To our knowledge, this is the first report of an encephalopathy associated with synthetic opioid intoxication.
