[Open tuberculosis with radiologically negative cavity findings].

Non-cavernous bacillary tuberculosis is observed with relatively increasing frequency nowadays. Most patients affected have very few or no symptoms, and radiographs usually show circumscribed lesions. The essential feature is the low infection risk due to the small number of bacilli excreted.

[Cytology, lactate dehydrogenase, and creatine kinase in CSF in mild head injuries (author's transl)].

Cytology, lactate dehydrogenase, and creatine kinase in cerebrospinal fluid were investigated 6-72h after mild head injuries in 59 patients aged 16-49 years. Significant differences were not found in creatine kinase. Lactate dehydrogenase, however, was significantly more elevated in mild cerebral contusions compared with concussions 24h after head injury.
