In a study of 60 elderly patients in a general hospital referred for psychiatric assessment, the commonest psychiatric disorders were depressive illness (41.6%) and dementia (35.0%). Patients with depression (mean age 69.5 years) were a younger age group compared with dementia (mean age 75.8 years)--this difference is statistically significant (p less than 0.01). Seven patients with depression were admitted for attempted suicide and 5 were referred because of headache and chest discomfort. The main reasons for referral of patients with dementia were disturbed and confused behaviour. The other psychiatric disorders in the sample were delirium (6.7%), paraphrenia (6.7%), alcohol dependence syndrome (5.0%) and anxiety neurosis (5.0%).

Some aspects of typhoid fever in 77 children are discussed. There were 48 boys and 29 girls and their ages ranged from 1 month to 12 years. The patients were treated with chloramphenicol 100 mg/kg/d during the first 2 weeks and with either amoxycillin (100 mg/kg/d) or ampicillin (200 mg/kg/d) during the third week. The average duration of fever was 5.2 days. There was 1 relapse and 1 child, a baby aged 1 month, died. The correct diagnosis was not suspected by the referring doctor in 38% of the patients. On admission the commonest complaints were fever, abdominal pain, diarrhoea, headache and vomiting. The commonest findings on examination were tenderness or distension of the abdomen, apathy or delirium, rhonchi or crepitations, liver enlargement and meningism. There was anaemia (Hb less than 10 g/dl) in 23% and lymphopenia (less than 1500/microliter) in 43% of the patients. The differential white blood cell count revealed 5% or more unsegmented neutrophils in 32% of the patients, while 25% had 10% or more band cells. Two patients (sisters) failed to respond after 15 and 16 days of therapy with chloramphenicol and ampicillin because of resistant Salmonella typhi and were successfully treated with co-trimoxazole. Practitioners caring for black patients should always be on the alert for typhoid fever; some patients may not respond to chloramphenicol or amoxicillin. During the acute phase milk feeds are best replaced by soya products because of abdominal distension or aggravation of diarrhoea by milk.

In 1963, acute trichinosis was recognized in four patients at the Ottawa Civic Hospital. One presented with cavernous sinus thrombosis and sixth nerve palsy. A second had a severe systemic infection with myocarditis; the signs of myocarditis appeared in the third week. Electrocardiographic abnormalities included T-wave flattening, prolongation of PR interval and QRS complex, and non-specific changes in 25%. Central nervous system involvement occurred in the second week with general symptoms (headache, delirium and psychotic behaviour), followed in the third week by focal signs (nerve palsy, convulsion, pareses and coma).The incidence of trichinosis in the U.S.A. fell from 15.9% before 1948 to 4.5% in the period 1948-1963. The Canadian incidence in the period from 1940 to 1943 was 5.6%. In a survey in Ottawa using the Baermann digestion and compression methods, four positive cases were found out of 500 diaphragms examined. These figures indicate the success of the public health regulations aimed at controlling trichinosis. A gastrocnemius muscle biopsy is still an invaluable diagnostic tool, especially in critically ill patients with negative skin tests and no eosinophilia.

Among patients with renal failure, there have been impressive modifications of both the duration and quality of life as a result of dialysis, renal transplantation, and improved medical management. However, patients who have renal failure continue to manifest a variety of neurologic disorders. Patients with chronic renal failure who have not yet received dialytic therapy may develop a symptom complex progressing from mild sensorial clouding to delirium and coma, with tremor, asterixis, multifocal myoclonus, and seizures. Even after the institution of otherwise adequate maintenance dialysis therapy, patients may continue to be afflicted with more subtle nervous system dysfunction, including impaired mentation, generalized weakness, and peripheral neuropathy. The central nervous system disorders of both untreated renal failure and that persisting despite dialysis are referred to as uremic encephalopathy. The dialytic treatment of end stage renal disease has itself been associated with the emergence of two distinct, new disorders of the central nervous system: Dialysis dysequilibrium and dialysis dementia. The dialysis disequilibrium syndrome consists of headache, nausea, muscle cramps, obtundation and seizures, and is a consequence of the initiation of dialysis therapy in some patients. Dialysis dementia is a progressive, generally fatal encephalopathy which affects patients on chronic hemodialysis. This disease also appears to be a complication of the therapy for renal failure.

A patient with multiple enteric fistulae, after months of parenteral hyperalimentation, developed, severe depression accompanied by delirium, dermatitis, pallor, paresthesia, nausea, vomiting, anorexia, and headaches. His symptoms improved after treatment with parenteral biotin. Biotin-deficiency should be suspected in patients on hyperalimentation (without biotin supplementation) who develop similar symptoms.

Methyl bromide (MeBr) is used as an insecticide fumigant. Four deaths and three recent hospitalizations have resulted from exposures to MeBr in Dade County, FL. Six cases occurred during burglaries of tented houses over a nine-month period. In four lethal exposures, the symptoms of nausea, vomiting, and malaise preceded fulminant respiratory failure. Two of these also had seizures, delirium, and agitation. Serum or plasma bromide ion levels ranged from 40 to 583 mg/L. Pulmonary edema, hyaline membranes, and hemorrhagic alveolitis were present at autopsy along with varying degrees of cerebral edema. The nonlethal exposures resulted in symptoms of conjunctival irritation, headache, or nausea. Plasma bromide concentrations varied between 17.5 and 321 mg/L. Methyl bromide characteristics, use, morbidity, and mortality in Florida during the past 25 years are reviewed. Remedies for illegal entry are proposed.

Tick-bite fever, the variety of tick typhus occurring in southern Africa, is caused by Rickettsia conori var. pijperi and is transmitted by hard or ixodid ticks. It is usually a mild disease, especially in children and young adults, but in middle-aged and elderly patients (and sometimes in young adults) it may assume a severe form. This is characterized by high fever, severe headache, delirium, stupor and occasionally coma, and a profuse maculopapular rash which becomes haemorrhagic and is associated with petechiae in the skin and later, but rarely, by the development of gangrene of the fingers and toes. During these severe attacks the central nervous system may be involved and marked disorders of liver and kidney function sometimes lead to kidney failure and the need for treatment and dialysis in an intensive care unit. Three illustrative cases are described in which diagnosis was delayed. One patient died; 2 patients responded to administration of tetracycline. The danger of allowing tick-infested dogs onto one's bed is stressed. Infections transmitted by dog ticks tend to be more severe than those acquired via ticks from the bushveld, possibly because they so often occur in middle-aged and elderly patients. Serological tests have recently indicated that there are antigenic differences between 'suburban' and 'bushveld' strains; these clearly require further study.

Patients with renal failure may manifest a variety of neurologic disorders. Patients with chronic renal failure who have not yet received dialytic therapy may develop a symptom complex progressing from mild sensorial clouding to delirium and coma, with tremor, asterixis, multifocal myoclonus, and seizures. After the institution of adequate maintenance dialysis therapy, patients may continue to be afflicted with more subtle nervous dysfunction, including impaired mentation, generalized weakness, and peripheral neuropathy. These central nervous system disorders are referred to as uremic encephalopathy. The dialytic treatment of end-stage renal disease has itself been associated with the emergence of two distinct, new disorders of the central nervous system; dialysis dysequilibrium and dialysis dementia. The dialysis disequilibrium syndrome consists of headache, nausea, muscle cramps, obtundation, and seizures, and is a consequence of the initiation of dialysis therapy in some patients. Dialysis dementia is a progressive, generally fatal encephalopathy which affects patients on chronic hemodialysis. There are at least three different forms of dialysis encephalopathy: sporadic, epidemic; and that associated with renal disease in children. In addition to the foregoing neurologic diseases which are specifically related to uremia and/or dialysis, a number of other neurologic disorders occur with increased frequency in patients with end-stage renal disease on chronic hemodialysis. These include subdural hematoma, electrolyte disorders, vitamin deficiencies, drug intoxication, hypertensive encephalopathy, and acute trace element intoxication. Renal transplantation is associated with a variety of central nervous system infections, reticulum cell sarcoma, and central pontine myelinosis. The present manuscript will review the clinical, structural, and biochemical components of those neurologic disorders which are peculiar to the uremic state and its treatment with dialysis.

General anesthesia offers greater comfort for both the abortion patient and the operator. The combination of diazepam and ketamine which is rapidly reversible and offers a moderately deep anesthesia was used in 127 voluntary abortions and 3 therapeutic abortions. Patients ranged in age from 14-40 years and averaged 26, with 58% under 26. Patient weights ranged from 40-82 kg and averaged 56 kg. 43% were primaparas and average parity was 2.5. The average duration of the prenancy was 8.1 weeks. 10 patients were obese, 1 was asthmatic, 1 was a controlled hypertensive, 3 had cardiopathies, and 4 each had hepatitis and meningitis. 1 had treated epilepsy and 2 had serious depressive syndromes. 3 women had previously had voluntary abortions, 9 had had miscarriages, and 1 had had an extrauterine pregnancy. 17% had no fear or anxiety before the procedure, 56% had moderate levels, 28% had significant levels, and 19% had very high levels. 94% of the procedures were done by aspiration and in most cases a preliminary insertion of laminaria was done. The average duration of the procedure was 5 minutes, with extremes of 2 and 25 minutes. Patients were premedicated 1 hour before the procedure with intramuscular injections of 10 mg diazepam and 1/4 mg of atropine. For the induction, a butterfly needle with an antireturn system was used to inject 10 mg of diazepam and 1/4 mg of atropine diluted in 20 ml of distilled water. The patient was placed in the gynecological position and, if necessary, 5 mg of diazepam were added. Between .5-1 mg/kg of ketamine were injected in 10-15 seconds. The same dose was reinjected if the anesthesia was insufficient or the procedure was prolonged. A mixture of 40% oxygen and 60% nitrous oxide was administered if necessary. Patients remained in bed for 6 hours after awakening. 85% of patients received total doses of ketamine of .70mg/kg or less. Average duration of anesthesia was 9.2 minutes, with durations of less than 15 minutes in 94% of cases. On awakening 5% of patients had nausea and vomiting. 16% had minor psychic disturbances or disorientation, 8% had moderate problems with vocalization, and 2% had hallucinatory delirium with agitation. Overall, 20% of patients experienced headaches, 11% nausea, and 9% dizziness. It was concluded that the combination of diazepam .2 mg/kg and ketamine .5-.7 mg/kg provides well tolerated light anesthesia utilizable for outpatient abortions.

A 22-year-old woman was admitted following the sudden onset of severe headache and loss of consciousness. On admission, she was delirious with nuchal rigidity. A lumbar puncture showed bloody spinal fluid. Laboratory studies revealed no abnormalities. Her consciousness state became clear 2 days after the attack. Computerized tomography taken 7 days after the attack revealed intraventricular hemorrhage in the right trigonum. Emergent right carotid angiography was performed. The intraventricular extravasation of contrast media was shown in the region of the right trigonum. One hour after the angiography, she was semicomatose with left flaccid hemiplegia. Reexamination of computerized tomography revealed diffuse intraventricular hemorrhage and periventricular intracerebral hematoma in the right parieto-temporal lobe. Emergent operation was performed and intracerebral hematoma was extirpated. Good postoperative results were obtained after ventriculoperitoneal shunting 46 days after removal of the hematoma. In our review of the literature, intraventricular extravasation of contrast media through primary intraventricular hemorrhage has not been reported.U
