ABSTRACT
Background: Thrombophilia is an alteration of hemostasis that increases the risk to venous or arterial thrombosis. This condition may be the underlying cause of retinal vein thrombosis. Aim: To study the presence of thrombophilia in patients with retinal vein thrombosis. Patients and methods: Prospective study of 55 patients aged 22 to 86 years, with retinal vein thrombosis (central or branch). Antithrombin III, coagulant protein C, functional protein S, resistance to activated C protein, homocysteine, prothrombin G20210A gene, lupus anticoagulant and anticardiolipin antibodies were measured in all. Results: Seventeen patients had thrombophilic markers (antiphospholipid syndrome in seven, hyperhomocysteinemia in six and resistance to protein C in three). Of these 17 patients, 53percent had high blood pressure, 35percent an abnormal serum lipid profile and 23percent a personal history of thrombosis. The thrombosis was central in 12 (ischemic in four) and of a branch in five (ischemic in two). Conclusions: Thrombophilic markers must be assessed in patients with retinal vein thrombosis.

Objetivo: Evaluar el efecto de la inyección de espuma de polidocanol como sustancia esclerosante vascular en la reducción del tamaño de hemangiomas y linfangiomas orbitarios. Material y Métodos: Estudios prospectivo intervencional de 2 casos con diagnóstico de hemangioma capilar, 7 casos de linfangioma de la región orbitaria y 1 malformación vascular superficial preseptal, que recibieron una o más inyecciones de polidocanol intralesional. Se evaluaron el tipo de tumor, disminución de su tamaño, variación de ptosis palpebral, proptosis y presencia de complicaciones con el procedimiento. Resultados: Se realizaron 4,5 inyecciones promedio con una dosificación final de 0,6 cc al 0,5 por ciento de polidocanol. El seguimiento promedio fue 16,2 meses. Todos los pacientes redujeron el tamaño de la lesión significativamente. La principal complicación fue dolor postinyección. Conclusiones: El uso de inyecciones de polidocanol en el tratamiento de hemangiomas capilares y linfangiomas orbitarios sería una alternativa novedosa y efectiva para reducir el tamaño de las lesiones sin mayores complicaciones.

A Multiple Myeloma (MM), IgG-l stage III-A was diagnosed in a 41-year-old-man. After VAD cycles IgG decreased from 7.5 to 2.4 g/dL. were mobilized with cyclophosphamide and 10 µg/Kg G-CSF. Three days after the collection of peripheral stem cell, the patient had fever, nausea, vomiting, liquid stools, shoulder and knee arthralgia and dehydration. Upper GI endoscopy showed esophageal candidiasis and ulcerative necrotic lesions both in stomach and duodenum; the biopsy confirmed necrosis. Simultaneously, the appearance of purpura with maculopapular lesions of diverse sizes appeared in the feet progressing to the limbs and trunk. Hematuria and proteinuria were also observed. Skin biopsy showed leukocytoclastic vasculitis. Renal biopsy showed focal and segmental glomerulonephritis. Serum ANCA, cryoglobulins, anti-HCV and RF were negative, and serum monoclonal IgG was 1290 mg/dL. Daily treatment with iv methylprednisolone pulses for 3 days improved skin lesions and digestive involvement. Macroscopic hematuria and proteinuria improved after two months of steroid treatment
