It is well known that narcoleptic patients have DR2 and DQw-1 on HLA typing. The development of narcolepsy is considered to depend on the two factors; genetic predispositions and exogenous factors such as head trauma, encephalitis, etc., mainly affecting the brainstem or diencephalon. We reported a 46-year-old man who had occasional sleep attacks after suffering from left thalamic hemorrhage and pontine vascular disorders. Rehabilitation was markedly disturbed due to frequent episodes of cataplectic attacks which was triggered by emotional lability such as laughing, anxiety, and excitement. HLA type examination showed both DR-2 and DQw-1 loci in the proband and his four other siblings. His elder brother also suffered from mild excessive daytime sleepiness during his younger age, but it subsided gradually. Analysis of overnight polysomnography in the patient revealed remarkable paradoxical alpha-blocking and frequent sleep onset REM stages as typically observed in narcoleptic patients. MRI examination showed multiple small hemorrhages and infarctions in the pontine tegmentum, in addition to the left thalamic hemorrhage and multiple subcortical ischemic lesions. Concerning the mechanism of frequent cataplexy in this patient, it is postulated that increased emotional incontinence might have stimulated the descending reticular system in the brainstem which in turn may inhibit anterior horn motor cell activities. Methylphenidate was initially given to the patient, resulting in some relief of attacks, and addition of imipramine dramatically suppressed cataplectic attacks. Imipramine is considered to inhibit the excitatory afferent pathway to the brainstem suppressing the hyperactivity of descending motor inhibitory system due to its anti-muscarinergic action.

A case with two cerebral aneurysms, in which one at the origin of the left superior cerebellar artery (SCA) grew and presented with Weber's syndrome and obstructive hydrocephalus, is reported. The patient was a 69-year-old female, who had severe headache and vomited. On admission, neck stiffness was recognized. CT scan showed findings of subarachnoid hemorrhage. Angiograms demonstrated two saccular aneurysms at the right middle cerebral artery (MCA) bifurcation and at the origin of the left SCA. Craniotomy and neck clipping of the aneurysm at the right MCA was performed. After discharge, left oculomotor palsy appeared and gradually progressed. Severe headache and right hemiparesis suddenly occurred two years after the first attack. On the second admission, CT scan revealed high density on the brain surface and a well enhanced round lesion at the left ambient cistern. Left vertebral angiogram demonstrated increase in size of the aneurysm at the left SCA. The patient was discharged after conservative therapy. Drowsiness and urinary incontinence appeared, and she was admitted for the third time three years after the first admission. CT scan showed an enhancing mass lesion sized 25 X 30 mm beside the left midbrain and obstructive hydrocephalus. The aneurysm at the SCA no longer seen on the left vertebral angiogram. V-P shunt was performed. Both Weber's syndrome and obstructive hydrocephalus in this case indicate an aneurysmal natural history, in which aneurysm becomes gigantic and thrombosed spontaneously.

A woman, aged 33 years, presented with headache, drowsiness, and attacks of loss of consciousness with incontinence, during the eight months previous to admission. A CT scan showed a round cystic mass in the third ventricle which was interpreted as a colloid cyst. A myodil ventriculogramm showed the anterior part of the third ventricle completely occupied by tumour. Eleven months later, because of worsening of symptoms, a new scan was carried out, and the presence of an intraventricular tumour in the anterior part of the third ventricle was confirmed. The patient died four months later. The histological diagnosis of the previous biopsy, as well as the post mortem examination, showed a craniopharyngioma of the third ventricle. There was no macroscopic or histological involvement of the pituitary gland by the tumour.

Central pontine myelinolysis was found histologically in a young man who died with Hodgkin's lymphoma. Clinically he had developed a progressive peripheral sensory deficit, ataxia, quadriparesis, dysarthria, incontinence and drowsiness. This is the fifth case reported in the British literature. The pathogenesis and aetiology of this primary demyelinating disease are considered.

Earlier nonselective alpha 1-adrenergic blocking drugs such as phentolamine and phenoxybenzamine are now restricted to the pharmacological management of alpha 1-adrenergic crisis and phaeochromocytoma. Prazosin, the first selective alpha 1-blocker approved for the treatment of hypertension, became available in the mid-1970s. Additional alpha 1-blockers such as doxazosin and terazosin have been introduced during recent years. The undesirable effects of all members of this class are similar. Most adverse events can be attributed to reversible competitive antagonism of postsynaptic alpha 1-adrenergic receptors in tissues that sustain high levels of alpha-adrenergic sympathetic tone, e.g. resistance arteries, capacitance veins and the urinary bladder outflow tract. Orthostatic hypotension with a sensation of intense faintness and occasional syncope, can occur shortly after the initial dose. Aggravating factors include upright posture, intravascular volume depletion and concurrent administration of other medications that lower blood pressure, including all other classes of antihypertensive drugs. The problem is reduced or avoided by the choice of low starting doses, beginning treatment at bedtime and by minimising other risks. Among overall adverse effects, asthenia, dizziness, faintness and syncope predominate and occur in 10 to 20% of patients, leading to discontinuation of therapy in about half that number. Infrequent adverse events include headache, drowsiness, palpitations, urinary incontinence and priapism. Some patients experience a 1 to 2kg bodyweight gain which may be associated with secondary hyperaldosteronism. Tolerance appears to develop to the benefits of alpha 1-blockade in patients with congestive heart failure, but not in hypertension.(ABSTRACT TRUNCATED AT 250 WORDS)

Ifosfamide, a nitrogen mustard derived alkylating agent commonly used in the treatment of solid tumors, has been associated with neurotoxicity in 5-33% of treated patients. Encephalopathy most often occurs during or shortly following drug administration, with increased drowsiness or irritability, confusion, hallucinations, visual blurring, extrapyramidal dysfunction, cranial nerve abnormalities, incontinence, generalized muscle twitching, seizures, and coma reported in infants, children, and older adults. While most reported neurologic abnormalities associated with ifosfamide have been reversible, encephalopathy resulting in death has occurred. We now report an infant who developed ifosfamide-induced encephalopathy, loss of developmental milestones, progressive brain atrophy, and cessation of cranial growth. This is the first case of cerebral atrophy and loss of developmental milestones that has been reported in a pediatric patient treated with ifosfamide. Given the efficacy of this anti-neoplastic agent and its increasing use in pediatrics, further investigation is indicated, especially in infants where brain growth is ongoing.

Clozapine, used in the treatment of patients with schizophrenia resistant to other neuroleptic medication, is metabolized by the hepatic microsomal system to demethyl-clozapine and clozapine-N-oxide. Changes in clozapine serum concentrations have been documented after initiation of therapy with medications known to induce or inhibit liver microsomal enzymes. These interactions are of clinical importance when diminished efficacy or increased toxic effects of clozapine therapy occur. A 34-year-old schizophrenic man had increased clozapine serum concentrations, leukocytosis, and adverse effects as a result of concomitant erythromycin therapy given for suspected lower respiratory tract infection. Symptoms included somnolence, difficulty in coordination and ambulation, slurred speech, disorientation, and incontinence. The symptoms resolved after treatment with clozapine and erythromycin were discontinued, and treatment with clozapine was gradually resumed.

From 1986 to 1991, 13 patients at Northwestern Memorial Hospital were entered onto a pilot study designed to test the feasibility of treating children with medulloblastoma (11 patients) or primitive neuroectodermal tumors of the cerebral hemispheres (2 patients) with hyperfractionated craniospinal radiotherapy (HFxRT). Follow-up times ranged from 10 to 96 months with a median of 53 months. The patients were prospectively divided among three treatment arms depending on prior treatment history, if any, and degree of surgical resection. The 3 patients in group I had undergone gross total resection of the primary site, receiving 64.8 Gy to the primary site and 31.2 Gy directed to the craniospinal axis (CSA). Of these 3 patients, patient 1 had residual disease in the thoracic spine at T-10. The 8 patients in group II, who had gross residual disease remaining at the primary site, received 72 Gy to the primary site and 34 Gy to the CSA. Five of these eight patients in group II also received 8-in-1 chemotherapy. The 2 patients in group III had already failed chemotherapy and were then treated with 60 Gy to the primary site and 26 Gy to the CSA. Of the 11 patients in groups I and II, 7 of the 11 (64%) have never recurred. Two of the three group-I patients have not recurred, and 5 of the 7 group-II patients have not recurred. In addition, patient 7 (group II) remains alive after salvage with bone marrow transplant, following a local failure bordering the tentorium. Unfortunately, neither of the group-III patients could be salvaged with HFxRT. Acute/subacute toxicities included 7 cases of external auditory canal or skin desquamation, 2 cases of postradiation somnolence, and 1 case each of poor wound healing and neutropenia. Chronic toxicities included hypothyroidism in 2 patients and growth problems in 2 patients. Neuropsychologic complications affected only the 3 youngest patients in the study. Three patients developed neurologic sequelae attributed to radiation, including 1 with progressive urinary incontinence, 1 who developed a transient ischemic attack, and 1 who became progressively ataxic. Our research, although based on a small number of patients, suggests that hyperfractionated radiation therapy to craniospinal access is feasible and that the survival results are favorable. This treatment strategy should be further explored in a phase-III randomized trial.

A 61-year-old man with multiple subcutaneous, ileocecal and neurologic manifestations was reported. Histological examination of subcutaneous and ileocecal mass showed non-Hodgkin's lymphoma (diffuse medium cell type [LSG classification]), B-cell type. Headache, somnolence and incontinence of urine were considered owing to the CNS involvement by lymphoma cells. The cranial CT findings showed diffuse spread involving the lateral and third ventricle and hypothalamus with adjacent edema. Then he was treated by VEMP regimen and repeated intrathecal MTX injections. The neurologic remission with improvement of cranial CT findings was obtained and he has been free of the disease for 15 years.

This study was performed to compare the efficacy of tropisetron, droperidol, and saline in the prevention of postoperative nausea and vomiting (PONV) and to compare the possible adverse effects of these drugs in gynecologic incontinence surgery. Using a randomized, double-blind study design, we studied 150 women undergoing gynecologic incontinence surgery with standardized general anesthesia. At the end of surgery, the patients received either tropisetron 5 mg, droperidol 1.25 mg, or 0.9% saline intravenously (i.v.). As a rescue antiemetic, the patients received metoclopramide 10 mg i.v.. The episodes of nausea, retching, and vomiting; the need for rescue treatment; and the type and severity of adverse events were recorded at four occasions during the 48-h observation period. Pain, anxiety, drowsiness, and general satisfaction were also evaluated on a linear numerical scale of 0-10. Complete response (no PONV within the 48-h observation period) occurred similarly in the study groups (tropisetron 25%, droperidol 22%, and placebo 18%). Tropisetron and droperidol had no effect on the incidence of nausea and retching. However, the incidence of vomiting was significantly less in the tropisetron group than in the placebo group (tropisetron 19%, droperidol 45%, and placebo 57%). The number of emetic episodes (retching and/or vomiting) per patient within 48 h was significantly decreased under tropisetron when compared with placebo (tropisetron 2.5 +/- 3.4, droperidol 4.2 +/- 6.1, placebo 5.9 +/- 7.1). With regard to adverse events, the patients in the droperidol group had significantly more anxiety than the placebo group (2-6 h postoperatively), more drowsiness than the tropisetron and placebo groups (0-2 h postoperatively), and more dissatisfaction than the tropisetron (0-6 h postoperatively) and placebo groups (2-6 h postoperatively). We conclude that tropisetron given 5 mg i.v. during anesthesia in gynecologic incontinence surgery effectively prevents vomiting but not nausea and retching, while 1.25 mg i.v. droperidol fails to prevent any of these emetic symptoms and results in adverse events.
