High tension electrical burns of upper arms treated by segmental excision of necrosed humerus. An introduction of a new surgical method.

This paper describes treating high-tension electrical burns of the upper arms by segmental excision of the necrosed humerus. This is a new surgical method of treating local electrical burns. The authors use modification of traditional surgical method, shorten the course of treatment, and preserve the injured limb. However, this surgical method should not be used to treat all high-tension electrical burns of the upper arm, and should be used only under certain conditions. Therefore, it is important to grasp the operative indications.

Verdoglobinuria phenomenon in severe electrical burns.

Verdoglobinuria is considered to be an ominous sign of Pseudomonas aeruginosa septicaemia in burns. No report of the survival of a case with this phenomenon could be found in the literature. Stone et al. (1964) first reported verdoglobinuria as an important diagnostic basis for P. aeruginosa septicaemia in burns. A patient with high-tension electrical injury was admitted to our hospital burn department in 1977. Verdoglobinuria occurred. This patient is reported as follows. There was a large defect in the left chest wall with exposure of the heart and secondary P. aeruginosa pyothorax which happened during the early stage of injury. It led to septicopyraemic shock. The patient's urine was examined under ultraviolet rays, the fluorescence was ultrapositive. Verdoglobinuria was positive proof. After active measures were administered, the patient was out of danger from this septicopyraemic shock. The metabolism mechanism of verdoglobin, diagnostic effect of verdoglobinuria on P. aeruginosa septicaemia in severe burns and treatment are discussed.

Serial MRI studies in pathologically verified Balò's concentric sclerosis.

We report serial MRI studies in a patient with Balò's concentric sclerosis, who presented with a progressive weakness in the right limbs of 10 day duration. Serial MR images revealed several concentric lesions characterized by layer by layer of demyelinated and myelinated appearance and multiple plaques in the white matter. Pathological study of a biopsy of a concentric lesion (which was performed to rule out neoplasm) further confirmed this diagnosis. These MR findings resolved in correspondence with clinical improvement. The patient was almost completely normal 1 year later. In conclusion, in this case, we found that MRI could show the striking feature reminiscent of the histopathologic findings of Balò's concentric sclerosis and played an important role in antemortem diagnosis of this rare demyelinating disease.

MRI diagnosis of spinal cord infarction: report of a case.

A 62-year-old diabetic women developed acute quadriparesis. Her first symptom was clumsiness of the right limbs, which was followed shortly after by quadriparesis with severe left-sided symptoms. Sensory examination showed pinprick and thermal sensation deficits below the left T6 and right T8 dermatomes. An intramedullary infarction in the cervical cord at C5 to C6 levels was demonstrated by serial magnetic resonance imaging (MRI) studies with Gadolinium-DTPA (Gd-DTPA) enhancement. Based on the findings from this patient and 20 patients with spinal cord infarction reported in the literature, it was concluded that spinal cord infarct lesions are characterized by negative Gd-DTPA enhancement at the acute and chronic stages and positive enhancement at the subacute stage, 1 to 4 weeks after the onset of infarction.
