Tumoral calcinosis.

The authors present a case of tumoral calcinosis, a rare form of calcinosis due to the formation of "calcium tumours" in the vicinity of serous bursae. They discuss the clinical, anatomical and pathological features of the three principal forms of calcinosis, including the theories of pathogenesis. In the rare tumoral form the treatment is always radical excision.

[Prevalence of HBsAg and anti-HBs in hospital personnel].

The prevalence of serum HBsAg and Anti-HBs was studied in 201 staff members from two Renal Dialysis Units, one Medical and one Dermatological Division from two Hospitals in the Milano area. The overall prevalence of HBsAg was significantly greater among staff members (8.9%) as compared to controls (4.9%). On the contrary, the prevalence of Anti-HBs was only slightly higher in hospital personnel than in controls. Non-medical staff members (nurses, technicians) showed a prevalence of HBV markers (HBsAg and/or Anti-HBs) twice as high as medical staff members (46.1% vs 23.2%). When the prevalence of HBV markers was correlated to the duration of work in the hospital, a steady increase in the prevalence of Anti-HBs was observed. On the contrary, the prevalence of HBsAg rose in the first 3 years and remained constant thereafter. The prevalence of HBV markers was significantly higher among staff members from Renal Dialysis Units (HBsAg+ and/or Anti-HBs+:50%) than in the personnel from the Medical and Dermatological Divisions (32.4%). However, the difference was solely related to a higher prevalence of Anti-HBs in the former (42% vs 23%). This may reflect a higher risk of infection in Dialysis Units as compared to other Hospital Divisions. However, the difference might be magnified by the frequent use of HBIG in the Dialysis Units personnel.

CCNU chemotherapy in adult patients with tumors of the basal ganglia and brain stem.

The present investigation evaluates those few patients of our series with basal ganglia and brain-stem tumor who refused either surgical decompression and biopsy or radiation therapy. Four patients were suffering from tumors of the basal ganglia and three from brain-stem tumors; all the tumors were diagnosed by classical neuroradiological investigations and computerized tomography. The patients were given CCNU by mouth, 13 mg/sq m every 6 weeks. No toxicity was recorded. Mean survival was 19 weeks for patients with basal ganglia tumors and 48 weeks for those with brain-stem tumors. All patients were evaluated with respect to the quality of survival. Results were compared with those obtained in a control group of patients who received methylprednisolone therapy only.

Extracranial CSF shunting for infantile non tumoral hydrocephalus--a retrospective analysis of 360 cases.

A series of 360 consecutive extracranial CSF shunts performed between June 1960 and June 1976 for infantile non tumoral hydrocephalus is reviewed. The surgical methods used, the reasons for re-operation, the time distribution of post-operative complications, the causes of death and the long term results are analysed and discussed for each of the four groups: tetraventricular communicating hydrocephalus, triventricular hydrocephalus, obstructive hydrocephalus with a ventriculo-cisternal block and post-meningocele or post-myelomeningocele hydrocephalus.
