Intraretinal hemorrhage associated with visceral leishmaniasis / Hemorragia intrarretiniana associada à leishmaniose visceral

ABSTRACT Visceral Leishmaniasis, also know as Kala-azar, is a parasitic tropical disease caused by protozoa of the genus Leishmania donovani. It is an endemic disease in many countries. It affects approximately 1,5 million people every year, and when associated with mal-nutrition and co-infection it may be fatal. Fever, hepatosplenomegaly, and pancytopenia is its typical clinical picture. Ocular manifestations of Kalaazar are relatively rare and can affect either anterior or posterior segment of the eye. We report a patient with kala-azar presenting intraretinal hemorrhages that regress completely after the successful treatment for visceral leishmaniasis.

Infestación de los párpados de un niño por phthirus pubis / Eyelids infestation by phthirus pubis in a boy

A clinical case of phthirus pubis infestation of the eyelids in an eight year old boy is presented. He complained of a bilateral eyelids inflammation for the last two weeks which had not healed with a daily application of a collyrium. Physical examination showed the presence of small dark spheres, of approximately 1 mm. attached to the proximal extreme of the eyelashes. A microscopical examination of these elements permitted to identify adults and eggs of P. pubis. Neither insects nor eggs were found in the scalp of the patient. Treatment consisted in the extraction of the parasite elements by means of a fine forceps after the application of liquid vaseline in the eyelashes. A total of 23 adults insects and 32 eggs was removed. The boy proceeded from a boarding school, where none of the other 27 children was found infested and stayed there form monday to friday, going home for week ends.

Aislamiento de Acanthamoeba en lentes de contacto, estuches y soluciones preservadoras de usuarios del Departamento de Lentes de Contacto del Hospital Oftalmológico de Nuestra Señora de la Luz / Acanthamoeba cultures were isolate from 150 samples of contact lenses

Se aislaron diecinueve cepas del género Acanthaoeba, en 150 muestras constituidas por 65 lentes de contacto; seis se aislaron de 49 lentes hidrofílicos y dos de 16 lentes semirrígidos correspondiendo al 12.33 por ciento global de positividad. De las 75 soluciones preservadoras se aislaron diez cepas de Acanthamoeba; el mayor número de muestras positivas se observó con la solución de timerosal al 1 por ciento(7/30) y el menor con EDTA al 1 por ciento (1/15) e hidrogéno peroxidasa (2/15). El global de los aislamientos en soluciones correspondió al 13.33 por ciento. Sólo se encontró una cepa de Acanthamoeba en los estuches para lentes de contacto; la mayor parte de los aislamientos podrían corresponder a una amiba patógena, Acanthamoeba castellani, aunque para su clasificación se requiere de estudios complementarios con patrón isoenzimático y estudio al microscopio electrónico.
