ABSTRACT
The anterior tarsal syndrome, a compression of the deep fibular nerve under the inferior extensor retinaculum, is a very rare entrapment neuropathy. Its most important symptom is nocturnal pain on the dorsum of the foot. The distal motor latency of the deep fibular nerve is prolonged, and the EMG demonstrates an active and chronic denervation of the extensor digitorum brevis muscle. One case of complete lesion of the deep fibular nerve in the anterior tarsal tunnel is presented as well as a discussion of its physiopathology.

The occurrence of cerebral metastasis due to hepatocellular carcinoma (HCC) is uncommon. The authors present a case of cerebral metastasis as a primary manifestation of HCC without pulmonary involvement. The dissemination pathways, the intervention and the prognosis are discussed

Os autores relatam um caso de movimento ocular anormal denominado de "bobbing" ocular que consiste em um movimento no plano vertical, com deslocamento rápido dos olhos para baixo, seguido, após uma pausa, de retorno lento à posiçao inicial, em um paciente do sexo masculino, 50 anos de idade, portador de hemorragia pontina devido a hipertensao arterial maligna. É feita revisao na literatura especializada a respeito deste sinal e discutem-se suas apresentaçoes, localizaçao anatômica da lesao e o prognóstico.

In 1988, Podestá et al pointed out that injury increases duodenogastric reflux, DGR. Therefore, the objective of this was to compare the amount of DGR in normal subjects, C group, and in patients with head injury, T group. DGR was assessed by intravenous injection of 99m Technetium+HIDA followed by aspiration of gastric juice. The amount of DGR was reported as the total percentagem of the injected rediotracer recovered in the gastric aspirate. Reflux values did not differ significantly between the two groups, C group-median of 1,60 for percentage, range of 0,13 for percentage - 3,01 for percentage and T group-median of 1,12 for percentage range of 0,04 for percentage - 4,4 for percentage, p>0,10. Our results show ta DGR is not increased in patients with severe head injury

A case of traumatic occlusion of the middle cerebral artery in a 12 years-old child is reporter. This complication has been rarely observed, since cerebral angiography was substituted by computed tomography in patients with head injury in emergency rooms. The mechanisms involved in the physiopathology of this complication and its treatment are discussed
