1. The behaviour of medullary respiratory neurons was studied during fictive coughing and swallowing evoked by electrical stimulation of the superior laryngeal nerve (SLN) in decerebrate, paralysed and artificially ventilated cats. Fictive coughing, swallowing and respiration were monitored by recording activities of the phrenic, hypoglossal and abdominal… (More)
A controlled randomized study was carried out to evaluate the effects of chemotherapy in patients with brain metastases from lung carcinoma. One hundred patients were randomly divided into three groups at the time of diagnosis or after surgery for metastases. Group A received radiotherapy alone; Group B received radiotherapy and chloroethylnitrosoureas… (More)
The location and axonal projection of a type of respiratory neurones (termed bIE neurones), which show burst firing at the time of phase transition from inspiration to expiration, were studied in Nembutal-anaesthetized, paralysed and artificially ventilated cats. The bIE neurones showed maximum firing at the sharp decline of inspiratory activity. All of the… (More)
Meningiomas are often described as hormone-dependent because of their preponderance in females and their tendency to clinically manifest during or after pregnancy. We describe a case of meningioma that grew rapidly during two pregnancies over a 2-year period. The tumor's rapid growth was confirmed by high-resolution computed tomography. Its estimated… (More)
OBJECT Twenty-nine nonimmunocompromised patients with primary central nervous system (CNS) lymphoma were treated with high-dose methotrexate (MTX) therapy followed by irradiation. The authors investigated the correlation of infusion schedules with MTX penetration into cerebrospinal fluid (CSF), tumor response, and survival to develop a regimen that would… (More)
Extracellular recordings were made from a type of relay neurons of the superior laryngeal nerve (SLN) afferents in the vicinity of the retrofacial nucleus (RFN) in either pentobarbitone-anesthetized or unanesthetized and decerebrate cats, which were paralyzed and artificially ventilated. A total of 26 neurons that could be activated both orthodromically by… (More)
A new operative method for treating recurrent chronic subdural hematoma is presented. This method consists of complete obliteration of the subdural hematoma cavity and conversion of the hematoma cavity into epidural space. The procedure was carried out in three patients with recurrent chronic subdural hematoma, all of whom made a complete recovery.
We report the case of a 14-year-old boy with benign chondroblastoma in the occipital bone associated with a cerebellar hemorrhage. The clinical features, radiologic and histologic appearances, and histogenesis in this case are described. Other reports of benign chondroblastomas of the cranial bones are also discussed.
Five cases of subdural hematoma from arterial rupture (SDH-AR) are described and other 39 reported cases are reviewed. The average age of the patient is 59 and male to female ratio is 2:1. Fifty two percent of the patients have history of recent head injuries most of which are trivial. A very few patient have initial loss of consciousness. Approximately… (More)
