Susceptibility of brain and skin to bacterial challenge.

The brain is a uniquely protected organ. Once the protective barriers are overcome, the brain is susceptible to bacterial infection. Using a reproducible rat model, the susceptibility of brain tissue to challenge by S. aureus or E. coli was quantitatively compared to that of skin. Brain was significantly more susceptible to the presence of bacteria than was the skin of the scalp. The development of infection in skin required at least 10(5) organisms, while brain infection could be produced with as few as 100 organisms.

The significance of proteinuria and haematuria in Schistosoma haematobium infection.

The intensity and prevalence of proteinuria and haematuria were studied with urinanalysis reagent strips in a Gambian community in which the intensity of infection with Schistosoma haematobium was high. The level of proteinuria present was shown to be related to the intensity of infection. Follow-up for 12 months showed that infected subjects with heavy proteinuria had a good prognosis. These findings suggest that the urinary protein in such subjects is likely to originate from lesions in the bladder and ureters and that advanced glomerular pathology is probably rare. The relationship of the levels of proteinuria and haematuria to the egg count suggests they may be parameters which could have value as indications for chemotherapy. Detailed study showed that the effect of treating all the subjects who had both 30 mg/100 ml or more of protein and at least a trace of haematuria would have been very similar to treating all those with an egg count of 200 ova/10 ml or more. Since urinalysis with reagent strips is very simple and rapid it could have a role in mass chemotherapy campaigns, particularly those aimed at the identification and treatment of heavily infected subjects.

Production of experimental brain abscess in the rat.

Experimental evaluation of brain abscess has been inhibited by the lack of a simple and reproducible model in small animals. A stereotaxic headholder and slow infusion of 1 microliter of saline, containing a known number of bacteria, were used to produce brain abscess consistently in the rat. The natural history of the brain abscess produced by this technique closely simulated that found in the human clinical situation.

Preliminary observations on the use of Corynebacterium parvum in patients with primary intracranial tumors: effect on intracranial pressure.

It has been observed that patients with metastatic brain lesions developed neurologic symptoms when given Corynebacterium parvum. To obtain more information in patients with intracranial mass lesions, intracranial pressures (ICP) were measured or observed in six patients undergoing C. parvum therapy. All patients except two (one previously shunted, one recently operated) demonstrated a profound increase in ICP. It is presumed that either edema is formed within brain and tumor tissue (inasmuch as neurologic deterioration has not been observed in patients without an intracranial lesion) or transient increases in cerebral blood flow adversely alter an already compromised intracranial volume. Surgical decompression of tumor volume or use of Lasix may abort this response to C. parvum infusion.

Patients' knowledge of heart disease in general practice.

Interviews with 400 consecutive patients attending a general practice sought their knowledge of the signs and symptoms of an acute heart attack, what action they would take for such an event, and their understanding of the predisposing factors contributing to heart disease. The survey revealed poor recognition of the relevant signs and symptoms of an acute heart attack and lack of knowledge of some of the main predisposing factors associated with heart disease.
