Partial splenectomy, splenic autotransplantation, and immunization with pneumococcal vaccine have been reported to protect patients against overwhelming postsplenectomy infection, and this study was undertaken to evaluate these therapeutic alternatives. For this purpose 136 rats were divided into experimental groups: 34 controls, 34 splenectomy, 34 partial(More)
A new method for continuous external drainage of cerebrospinal fluid (CSF) for the treatment of CSF fistulas is described. In this system, CSF is withdrawn continuously from the lumbar subarachnoid space at a controlled flow rate calculated to be slightly less than the natural absorption rate of CSF. Controlled spinal drainage can be achieved using(More)
Massive bleeding into an intracranial neurinoma is a rare event. The 12th case of this particular occurrence, which was precipitated by weight lifting, is described and a review of the literature is presented. Risk factors for bleeding appear to be tumor size and vascularity. Presenting symptomatology is abrupt and includes headache, nausea, vomiting, and(More)
An experimental study was undertaken to evaluate the protective effect of heterotopic splenic autotransplantation in weanling rats. Rats were divided into three experimental groups: splenectomy, control, and splenic autotransplantation. Rats were challenged with i.v. type I pneumococcus. Bacterial bloodstream clearance and survival were determined. Splenic(More)
A convenient sampling method was developed for collection of volatile nitrosamines from large-volume air samples. Stainless steel tubes containing 0.3 g Tenax GC were employed to collect nitrosamines from 5-30 1 air samples. Nitrosamines were eluted from the sample tubes with diethylether to minimize formation of artifacts which were observed when thermal(More)
Fourteen patients with classic tic douloureux were treated with neurovascular decorapression of the trigeminal nerve at its zone of entry into the pons. In addition, selective rhizotomy of the portio major was performed in each patient. This combined procedure gave excellent relief of pain with no recurrences in a 23-month postoperative period.
