The case of a restrictive valve disease associated with cabergoline, an ergot alkaloid agonist used in the treatment of Parkinson's disease, is described. Cardiovascular and periodical follow-up assessment may be required when these drugs are prescribed.
Coronary artery obstruction during cardiac catheterization is rare. It is a serious complication and has been reported to occur in 0.15 to 0.5% of cases. Thromboembolism, air embolism and coronary dissection have been described as the most common causes of intraprocedural coronary occlusion. Aortic valve masses can also cause coronary obstruction. We report the case of a young woman with a complication and an incidental finding during angiographic procedure. A surgical treatment was needed.
PURPOSE: To test the hypothesis that long-term immunological response may be different after accustomed concentric and unaccustomed eccentric exercise in endurance-trained men. METHODS: Fourteen highly endurance-trained male runners performed two bouts of high-intensity exercise with at least 2-wk intervals between bouts. Concentric exercise consisted of a 60-min level run with a targeted heart rate of 80% VO2 peak. Eccentric exercise was conducted lying on a specially designed exercise rack, eliciting eccentric action of the musculus quadriceps femoris. Blood samples were taken before and 1, 6, 24, 72, and 144 h after exercise to determine creatine kinase (CK), C-reactive protein (CRP), and interleukin-6 (IL-6). Lymphocyte subset distribution was assessed using flow cytometry. RESULTS: We found a significant (P < 0.05) increase of CD4 (eccentric: 17%; concentric: 20%), CD3+/CD4+ (16 vs 19%), CD25+ (45 vs 29%), CD25+/CD4+ (27 vs 50%), HLA-DR+ (20 vs 15%), HLA-DR+/CD4+ (16 vs 67%), and CD19+/CD45+ (52 vs 103%) positive lymphocytes 1 h after both exercise bouts. However, eccentric exercise resulted in a significantly higher and longer (6 h) increase of CD25+/CD4+ and HLA-DR+/CD8+ lymphocytes and a peak increase of CK at 72 h. IL-6 and CRP increased only after concentric exercise within the first 24 h. Both exercises resulted in a decrease of monocyte activation (LFA-1: CD18+/CD11a+) after 6 h, with an increase for the eccentric exercise part after 24 h (P < 0.05). CONCLUSION: Accustomed concentric exercise mainly induced an acute-phase response, with increased CRP, IL-6, and activation of CD4 lymphocyte subsets. Unaccustomed eccentric exercise provided a delayed increase in CK and activation of monocytes and CD4+ and CD8+ subsets. Therefore, the immunological reaction depends not only on the type of contraction but also on the adaptation to the exercise.
BACKGROUND: In a Hull and Holderness Community NHS Trust audit of prescribing in unipolar depression, 55 patients were identified as taking a redundant conventional antipsychotic with no apparent diagnostic indication. Concerns regarding these patients' polypharmacy, duration of treatment, and risk of long-term or undetected side effects led to their being contacted with a view to the discontinuation of conventional antipsychotic treatment. METHOD: All case notes were scrutinized to validate, as far as possible, the diagnosis of unipolar depression without psychotic features. Patients were invited for a review of their medication. Ratings of symptoms (Brief Psychiatric Rating Scale), depression (Hamilton Rating Scale for Depression), motor side effects (Abnormal Involuntary Movement Scale), and personal function (Independent Living Skills Survey) were made before and after conventional antipsychotic discontinuation. The study was conducted Autumn 1999-Spring 2000. RESULTS: None of the 55 patients were deemed to present comorbid depression secondary to any other diagnosis. One patient could not be contacted; 14 patients, who tended to be older, refused the review. Of the remaining 40 who were seen, 25 had already discontinued antipsychotic treatment; their chronicity of illness was half that of the 15 patients continuing antipsychotic treatment. However, only 11 of these 25 patients had their medications discontinued under consultant psychiatrist supervision following the audit; 14 patients had stopped medication of their own volition, or for unclear reasons. Of the remaining 15 patients, 13 had their conventional antipsychotic discontinued by us. There were clinically and statistically significant improvements in symptoms and side effects after antipsychotic treatment was discontinued, and a statistically significant improvement in personal health care function. CONCLUSION: In this small sample, discontinuation of nonindicated conventional antipsychotic treatment was associated with clear benefits. Conventional antipsychotics should be used with caution in nonpsychotic depressed patients, particularly in the long term. Reluctance to discontinue medication in more chronic patients may be misplaced.
