[Tuberculous prostatitis in a previously healthy Danish man]. / Tuberkuløs prostatitis hos en tidligere rask dansk mand.

Prostatitis is a common disease, but rarely caused by Mycobacterium tuberculosis. We present a case where a Danish man was referred to our outpatient clinic with lower urinary tract symptoms. Prostate biopsies revealed granulomatous prostatitis with caseous necroses and acid-fast bacilli. Urine and sputum were culture positive of M. tuberculosis and treatment was initiated. Tuberculosis is still an important diagnosis and should be remembered in urologic investigations. Extra pulmonary symptoms may be the initial presentation and lack of awareness could lead to increased spread.

Neocortical glial cell numbers in Alzheimer's disease. A stereological study.

Most studies agree that specific regions of the hippocampus and specific subcortical regions show neuronal loss in Alzheimer's disease (AD). The aim of the study was to use design-based stereological methods to obtain an estimate of the total glial cell population in 14 AD cases and 20 controls to determine whether brains from AD patients have a different number of neocortical glial cells than controls. The mean total number of neocortical glial cells was 25.9 x 10(9) for the AD group and 29.1 x 10(9) for the control group, 2p = 0.18. The mean total number of neocortical neurons was 18.9 x 10(9) for the AD group and 21.2 x 10(9) for the control group, 2p = 0.059. Estimates of the sum of all glial cells and neurons in the neocortex were in the order of 50 billion cells with a glia to neuron ratio of 1.37 in both groups.
