A case of human rabies is reported showing a peculiar course in some respects. The lack of a satisfactory history concerning an animal bite 5 months earlier as well as a misleading psychiatric history led to difficulty and delay in reaching a diagnosis. ⋯ The clinical course and the pathological findings are described in detail and the etiology and prognosis of the disease are discussed. The latter remains rather hopeless de spite modern intensive care.

Three different low pressure cuffed endotracheal tubes (Lanz, Portex soft-seal, Kamen-Wilkinson) were studied in cadaver tracheas and patients in our intensive care unit during ventilation. In the air filled low pressure cuffs without controlled pressure system the cuff pressure and the ventilation pressure are almost identical. Rises of intrathoracic pressure during mechanical ventilation are reflected by increased cuff pressure. Tubes with controlled pressure system or foam-filled cuffs have lower peak cuff pressures, especially during sighing, coughing and suctioning.
