Cavitation is a most unusual radiological feature of Pneumocystis carinii pneumonia (PCP). Autopsy evidence of cavities in PCP is poorly documented. We describe a case of fatal PCP occurring in a patient with the acquired immune deficiency syndrome; the PCP was associated with radiological as well as autopsy evidence of large intrapulmonary cavities. These(More)
Two cases of myocarditis complicating meningococcal septicaemia are presented. Neisseria meningitidis infection with bacteraemia is a common entity but the important complication of myocarditis has not often been described. The autopsy findings in 1 of the 2 patients described further illustrates the significance of myocarditis. The pathology, clinical(More)
A patient with pulmonary mucormycosis caused by Rhizopus oryzae was treated with a total dose of intravenous amphotericin B 2060 mg which resulted in medical cure. This is the first reported medical cure in the RSA of pulmonary mucormycosis. Mucormycosis with brachial plexus involvement and Horner's syndrome has not been previously reported.
In the state space approach to linear systems three concepts play a central role: realization-to construct an internal (state space) description or model for a given input-output description; reachability-to determine if it is possible to reach any given final state from any initial state by choosing suitable inputs; and observability-to determine if it is(More)
The Kalman duality between the reachability and observability of finite-dimensional linear systems is generalized to adjoint systems (in the sense of Arbib-Manes). The theory includes previous results on infinite-dimensional linear systems and linear systems over rings, and yields new results for classes of nonlinear systems such as bilinear and polynomial(More)
In 97 patients undergoing elective biliary (44) or colorectal (53) surgery, cases were randomly allocated to receive peri-operative prophylaxis with either cefoxitin (Mefoxin; MSD) or metronidazole, penicillin and tobramycin (MPT). Sepsis occurred in 3 of the biliary cases (6,8%) and in 16 of the colorectal cases (30,2%). In the colorectal group sepsis(More)
