Intractable pain in six cancer patients was treated with lumbar intrathecal morphine (two patients) and intraventricular morphine (four patients). Daily percutaneous injections of morphine through Ommaya reservoirs were made. Initially, 1 mg of lumbar intrathecal morphine resulted in pain relief for 10 to 14 hours, and 2.5 to 4.0 mg of intraventricular morphine gave relief for 12 to 24 hours. This treatment was continued for 3 to 7 months in three of the adults. Morphine requirements gradually increased. Side effects were minimal, and there were no complications.

Ten patients with dementia due to normal-pressure hydrocephalus were evaluated prospectively according to a planned, longitudinal protocol for 4 to 12 months. Information recorded at each visit included clinical history, medical and neurological examination, psychometric scoring by Mini-Mental Status Questionnaire, measurement of ventricular size and local cerebral blood flow, and partition coefficients (local lambda changes) (1 lambda) by xenon contrast computerized tomography scanning. Cerebrospinal fluid shunting was carried out in eight cases. Serial evaluations were repeated at intervals up to 8 months after shunting, and demonstrated that the ventricles decreased in size and periventricular hypodensities decreased. White matter 1 lambda values and blood flows and cortical gray matter flows progressively increased for 3 months after shunting, and remained increased except for one case complicated by chronic alcoholism. Clinical recovery correlated with improved cerebral perfusion. There were returns of urinary continence and improvements in gait and usually in activities of daily living. Mentation was the last factor to improve. Factors negatively influencing cerebral perfusion and clinical recovery were shunt failures and various contributing causes of dementia.

Gorlin's syndrome, also known as multiple basal cell carcinoma syndrome, is a familial tumor condition with autosomal-dominant inheritance. Patients develop multiple basal cell carcinomas beginning in childhood. They also have a typical dysmorphic facies, skeletal malformations, and a particular type of epithelial cyst of the jaws. Recent evidence localizes a Gorlin's syndrome locus on chromosome 9 at band q31. Both tumors and malformations of the central nervous system occur with Gorlin's syndrome. Medulloblastoma is the primary brain tumor most frequently associated with this syndrome; over 40 such cases have been reported. However, only seven cases of meningioma associated with Gorlin's syndrome have been described. The authors report the case of a woman with Gorlin's syndrome whose mother and maternal grandfather also had the condition. The patient was found to have a medulloblastoma at 4 years of age and presented with a large bifrontal meningioma at 19 years of age. The meningioma was histologically malignant and had a complex karyotype with multiple translocations including a t(5;9) with the breakpoint on chromosome 9 located at 9q32. The constitutional karyotype of the mother was normal. No mutations of exons 5 to 9 of the p53 gene were detected using single-stranded conformational polymorphism analysis.
