Improved autonomic neurocardial balance in short-term abstinent alcoholics treated with acamprosate

Standardized investigations on resting heart rate variability (HRV) should provide more information on acamprosate's human pharmacodynamic properties because acamprosate interacts with several neurotransmitter systems which are also involved in maintaining autonomic neurocardiac balance. We performed HRV measurements prospectively in 69 healthy controls and 19 chronic alcoholics to prove the hypotheses that: (1) compared to healthy controls, chronic alcoholics show disturbances in neurocardiac vagal function; and (2) in alcoholics, acamprosate treatment (6-8 days) should further decrease parasympathetic activity if acamprosate interacts with central gamma-aminobutyric acidA receptors in vivo. Cardiovagal dysfunction was initially present in 21% of the alcoholics. After treatment. however, their neurocardiac sympathetic-parasympathetic balance improved significantly.     

Hypertrophic osteopathy and dysgerminoma in a mare

A case of hypertrophic osteopathy is described in a mare with a vague history of abdominal discomfort over the preceding 12 months. Bony swellings were obvious in the pastern area of both forelegs. There was a dysgerminoma of the left ovary that had metastasised to several abdominal lymph nodes and had infiltrated the posterior vena cava. There was no gross thoracic involvement although there was histologic evidence of tumour metastasis in pulmonary arterioles.     

Duration of hospitalization for acute bacterial meningitis at Boston City Hospital during 12 selected years, 1935-1972

An analysis is presented of the duration of hospitalization of the patients with acute bacterial (purulent) meningitis which occurred at Boston City Hospital during 12 selected years between 1935 and 1972. Considerable differences in the length of stay in the hospital were noted depending on the bacterial etiology, whether the infection was present on admission or acquired within the hospital, and, of course, whether the patient survived or died. Most of the deaths occurred within the first few days after admission or after the diagnosis was first established, but even among fatal cases, the survival time differed depending on the etiology and site of acquisition of the infection. During the years after effective antibiotics became available the hospital stay of patients who survived after admission for meningococcal, influenzal, or pneumococcal meningitis was shorter than before. The same has not been true for meningitis caused by other gram-positive cocci, gram-negative rods, or mixed infections, probably reflecting the relative ineffectiveness of antimicrobial therapy in such patients.
