Psychotic symptoms and a diagnosis of schizophrenia follow an initial diagnosis of tic disorder.

We report a patient with a tic disorder who later developed psychotic symptoms and was diagnosed with schizophrenia.

[Rapid resolution of acute subdural hematoma; report of two cases].

We reported two cases of rapid resolution of acute subdural hematoma. Case 1, a 21-year-old female, sustained head trauma and became unconscious for about 15 min. Probably she was suffering from posttraumatic amnesia for about 1 day. On admission J.C.S and G.C.S were 20 and 9 (2 + 2 + 5) points, respectively. Neurological examination showed no abnormalities. An initial computed tomography (CT) scan taken 2 hours after the injury showed a high dense subdural hematoma on the left cerebral hemisphere and hemispheric swelling. She was conservatively treated. A follow up CT scan taken 8 hours after the injury disclosed rapid disappearance of the hematoma and cerebral swelling. Case 2a 23-year-old male, sustained head trauma and became unconscious for about 30 min. On admission J.C.S and G.C.S were 1 and 14 (4 + 4 + 6) points, respectively, and slight right hemiparesis was noted. An initial CT scan taken 2 hours after the injury showed subdural hematoma of the left cerebral hemisphere and hemispheric swelling. He was conservatively treated. A follow up CT scan taken 24 hours after the injury revealed almost complete disappearance of the subdural hematoma and cerebral swelling. It was suggested that the rapid resolution of acute subdural hematoma was attributable to redistribution due to decrease of ICP, and washing out by cerebrospinal fluid.

[Effect of exercise on rats with renal injury].

Effect of exercise on rats with renal injury was studied. Nephritis was induced in rats by injection of anti-GBM antibody followed by ligation of a branch of the left renal artery after nephrectomy of the right kidney. Moderate daily treadmill exercise was forced on these experimental rats for ten weeks. Sedentary nephritic rats that received the same treatment described above served as controls. The sedentary nephritic rats suffered progressively increasing proteinuria during the time course of the experiment, whereas the nephritic rats with daily treadmill exercise experienced less proteinuria. Mild proteinuria was induced by daily treadmill exercise forced on non-nephritic rats that had received only nephrectomy of the right kidney, but no NTS injection. Light microscopy and immunofluorescence microscopy revealed severe glomerular injury in the sedentary nephritic rats, however, less glomerular injury was seen in nephritic rats with treadmill exercise. Serum cholesterol level was higher in the sedentary rats than in the rats with daily treadmill exercise. The results suggest that daily exercise by nephritic rats will not aggravate renal injury.
