RESUMO
Myiasis is a term derived from the Greek word "myia", meaning invasion of vital tissue of humans or other mammals by fly larvae. The deposited eggs develop into larvae, which penetrate deep structures causing adjacent tissue destruction. It is an uncommon clinical condition, being more frequent in underdeveloped countries and hot climate regions, and is associated with poor hygiene, suppurative oral lesions, alcoholism and senility. Its diagnosis is made basically by the presence of larvae. This paper reports a case of oral and maxillofacial myiasis involving 273 larvae in a patient with epidermoid carcinoma without physical or neurological deficiency. The patient's management was antisepsis, larval removal and general care, before death after three months.

La meningoencefalitis amebiana primaria (MAP) es infrecuente. Describimos dos nuevos casos de MAP en pacientes Venezolanos. Caso 1, Varón de 10 años, con fiebre, cefalea, vómitos y debilidad generalizada, y antecedente de inmersión en un estanque de agua días antes del inicio de sus síntomas, falleciendo 72 horas después del ingreso. Caso 2, Varón de 23 años con historia de cefalea, fiebre, vómitos, somnolencia y cambios de conducta. El paciente falleció 40 horas después. El estudio neuropatológico en ambos casos reveló MAP por Naegleria fowleri. La encefalitis por amebas anfizoicas debe sospecharse en casos de meningoencefalitis asépticas.
Primary amebic menigoencephalitis (PAM) is rare. Two cases of PAM in Venezuelan patients are described. Case 1, a 10 year-old male with headache, fever, vomiting. The patient swam in a water reservoir before the onset of his disease. He died during his third hospital day. Case 2, a 23 year-old male with a history of headache, fever, vomiting, drowsiness, and behavioral disturbances. The patient died on his second hospital day. The diagnosis in both cases was PAM due to Naegleria fowleri. Central nervous system infection by free-living amebas should be considered in meningoencephalitides with bacterial-free cerebro-spinal fluid.
