The core tissue microflora of 40 patients who underwent tonsillectomies were examined with cultures, DNA probe tests, enzyme immunoassays, and direct immunofluorescence antibody tests for Chlamydia and Mycoplasma. We believe this is the largest and most accurate prospective study that has examined the role of Chlamydia and Mycoplasma in the core tonsil tissue of patients with recurrent or chronic tonsillitis. The data strongly indicate that, unlike acute tonsillopharyngitis, Chlamydia and Mycoplasma are not involved in recurrent or chronic tonsillitis. 相似文献

OBJECTIVE: The aim of this study was to assess changes in early and late haemodynamic status after the Norwood procedure (NP), caused by the implementation of right ventricle-to-pulmonary artery shunt (RV-PA). METHODS: A consecutive series of 68 children with hypoplastic left heart syndrome underwent NP: Group 1 (n=31) with the application of a modified Blalock-Taussig shunt and Group 2 (n=37) with RV-PA. Haemodynamic data from the early postoperative period (72 h after the operation) and cardiac catheterisation data, as well as blood tests before the hemi-Fontan procedure (HF) were analysed. Univariate (chi(2) test, Mann-Whitney's and Student's t-tests) and multiple regression analysis were carried out. RESULTS: In Group 1, circulatory collapse requiring resuscitation occurred in 15 (48.4%) children, within 72 h after the procedure. The resuscitation was unsuccessful in nine (29%) cases. The operative mortality (30 days) was 35%. In Group 2, two (5%) children died within the early and two (5%) within the late postoperative period. The postoperative course in the remaining children from Group 2 was uneventful. In Group 2 there was a significantly higher mean diastolic pressure after NP (P<0.05). The arterial pulse pressure after NP was significantly lower in Group 2 (P<0.05). Before HF, the application of RV-PA was associated with a lower Qp:Qs ratio (P=0.020), lower aortic pulse pressure (P=0.004) and lower aortic oxygen saturation (P=0.039). CONCLUSIONS: A stable haemodynamic status due to independent coronary perfusion, higher diastolic and lower pulse pressure is the most advantageous effect of RV-PA, resulting in a lower mortality and morbidity after NP. A lower Qp:Qs ratio eliminates the danger of the ventricular volume overload and ensures good conditions for the development of the pulmonary circulation before HF. 相似文献

Ethical issues in child and adolescent psychiatry consultation arise frequently but seldom are discussed in a public setting. This case of an adolescent victim of a surgical accident illustrates many aspects of consultation psychiatry. The consult question itself, of behavior management, is not unusual, although in this case the question is complicated by the sequelae of trauma, psychosocial chaos, and the staff's angry feelings toward the patient. In addition, potential surgical wrongdoing at the referring hospital brings up the more difficult ethical questions of the consultant's responsibilities, which must be to the patient and his family, as well as to the attending and referring physicians. 相似文献

A new cytochemical technique, sensitive to altered lysosomal membrane permeability of blood neutrophils, has been evaluated as a screening test for bacterial infection. This technique, for the lysosomal enzymes acid phosphatase and chloroacetate esterase, was compared with the neutrophil alkaline phosphatase and nitroblue tetrazolium tests. The mean score for each method was significantly higher in infected patients than in normal controls. There was, however, considerable overlap of individual scores between infected patients and ill, but uninfected, patients. This overlap limits the diagnostic value of existing cytochemical screening methods. 相似文献
