Acquisition of infection in adults is rare. It is unlikely, therefore, that reinfection will occur after successful eradication.

Cerebral blood flow (CBF) was measured during the 1st week of subarachnoid hemorrhage in 46 patients who were in a good clinical grade and had a proven ruptured intracranial aneurysm. The mean initial CBF in patients who developed cerebral ischemia was 42 ml/min-1/100 gm brain-1, which was significantly lower than in patients who did not develop cerebral ischemia (49 ml/min-1/100 gm brain-1). This reduced CBF was not secondary to raised intracranial pressure or angiographic spasm. Patients with a reduced CBF (less than 50 ml/min-1/100 gm brain-1) and diffuse subarachnoid blood on computerized tomography had a very high incidence (78%) of cerebral ischemia, despite a good clinical grade at the time of measurement. Serial CBF measurements are of value in monitoring the evolution of cerebral vasospasm.

SummaryThe chromosomes were examined in preparations made directly (without culture) from biopsy material from the affected area in eight cases with presumptive precancerous change (carcinoma-in-situ or dysplasia) of the cervix uteri and one of the vagina. The eight cervical lesions were entirely intraepithelial, but the vaginal one was associated with a small invasive carcinoma.-
