Propranolol-induced hypertension in treatment of cocaine intoxication.

The case of a patient with apparent cocaine toxicity and drug-mediated hypertension and tachycardia is presented. IV propranolol was used as the initial treatment for his hyperadrenergic state, resulting in a decrease in heart rate but a paroxsymal increase in blood pressure. The patient required nitroprusside for control of elevated blood pressure.

Rebound rib: stress-induced first rib fracture.

Reported are two cases of stress-induced fracture of the first rib in young, healthy basketball players. Presumably the fractures resulted from violent contraction of the scalene musculature. This is the usual method of production of stress-induced first rib fracture, but basketball-related cases have not been reported previously.

[Medulloblastoma. Report of 13 cases (author's transl)].

Thirteen patients with medulloblastoma were admitted to the Clinica Puerta de Hierro (Department of Radiotherapy) between 1964 and 1977. Two subtypes of medulloblastoma (classical and desmoplastic) with different histologic pattern, age of onset, clinical manifestations and clinical course have been identified. Radical surgery does not increase overal survival.

Multiwire proportional chamber system of the Fermilab single arm spectrometer.

We describe a system of two groups of multiwire proportional chambers and its special purpose interface used in the Single Arm Spectrometer (SAS) facility at Fermilab. The first set measures the coordinates of the fast particle going into the spectrometer arm with a space resolution down to +/-0.5 mm.
