BACKGROUND: The floating shoulder (ipsilateral fractures of the clavicular shaft and the scapular neck) is thought to be an unstable injury pattern requiring operative stabilization in most instances. This recommendation has been made with little biomechanical data to support it. The purpose of this study was to determine the osseous and ligamentous contributions to the stability of experimentally created scapular neck fractures in a cadaver model. METHODS: Standardized scapular neck fractures were made in twelve fresh-frozen human cadaveric shoulders. Each specimen was mounted in a specially designed testing apparatus and secured to a standard materials testing device. In group 1 (six shoulders), resistance to medial displacement was determined following sequential creation of an ipsilateral clavicular fracture, coracoacromial ligament disruption, and acromioclavicular capsular disruption. In group 2 (six shoulders), resistance to medial displacement was determined following sequential sectioning of the coracoacromial and coracoclavicular ligaments. RESULTS: The average measured force for all specimens (groups 1 and 2) after scapular neck fracture was 183 +/- 3.3 N (range, 166 to 203 N). The addition of a clavicular fracture (group 1) resulted in an average measured force of 128 +/- 10.5 N (range, 83 to 153 N), which corresponds to only a 30% loss of stability. Subsequent sectioning of the coracoacromial and acromioclavicular capsular ligaments yielded an average force of 126 +/- 9.1 N (range, 114 to 144 N), a 31% loss of stability, and 0 N, a complete loss of stability, respectively. Sectioning of the coracoacromial and coracoclavicular ligaments after scapular neck fracture (group 2) resulted in an average force of 103 +/- 8.4 N (range, 89 to 118 N), a 44% loss of stability, and 0 N, a complete loss of stability, respectively. CONCLUSIONS: Ipsilateral fractures of the scapular neck and the clavicular shaft do not produce a floating shoulder without additional disruption of the coracoacromial and acromioclavicular capsular ligaments. These and other unstable combined injury patterns are likely to be accompanied by substantial medial displacement of the glenoid fragment. 相似文献

The phosphodiesterase (PDE) inhibitor isomazole increased the force of contraction to 278.3 +/- 89.1% (n = 7) of the predrug value in ventricular trabeculae carneae isolated from nonfailing human hearts. This effect can be attributed mainly to a PDE III or a combined PDE III/IV inhibition since at the concentration of the maximal positive inotropic effect of isomazole, PDE III and PDE IV were completely inhibited. In explanted failing human hearts (end-stage myocardial failure, NYHA IV), isomazole increased the force of contraction only marginally to 110.1 +/- 10.7% of the predrug value. The lack of a distinct positive inotropic efficacy of isomazole in failing human hearts could not be explained by an impairment of PDE inhibition since the properties of the PDE I-IV isoenzymes separated by DEAE-Sepharose chromatography and the inhibitory effects of isomazole did not differ in both preparations. The positive inotropic effect of the beta-adrenoceptor agonist isoprenaline was also reduced in failing hearts. However, in the presence of isomazole, the diminished positive inotropic effect of isoprenaline was restored to values obtained with isoprenaline alone in nonfailing hearts. Thus, the decreased effect of inotropic drugs like isoprenaline or isomazole in preparations from failing human heart might be explained mainly by a diminished cAMP formation due to a defect in receptor-adenylate cyclase coupling. 相似文献

Hypereosinophilic syndrome (HES) is defined as chronic, unexplained hypereosinophilia with organ involvement. A subset of HES patients presents an interstitial deletion in chromosome 4q12, which leads to the expression of an imatinib-responsive fusion gene, FIP1L1-PDGFRA. These patients are diagnosed as chronic eosinophilic leukaemia (CEL). We treated seven CEL and HES patients, six of which expressed FIP1L1-PDGFRA , with imatinib using initial daily doses ranging from 100 to 400 mg. In a remission maintenance phase, the patients were treated with imatinib once weekly. All imatinib-treated patients achieved a complete haematological remission (CHR), and five of the six patients with FIP1L1-PDGFRA expression exhibited molecular remission. The decreased imatinib doses were as follows: 200 mg/week in three patients, 100 mg/week in two patients and 100 mg/d in the remaining two patients. For remission maintenance, imatinib doses were set at 100 mg/week in five patients and 200 mg/week in two patients. At a median follow-up of 30 months all patients remained in CHR and FIP1L1-PDGFRA expression was undetectable in five of the six FIP1L1-PDGFRA -expressing patients. These data suggest that a single weekly dose of imatinib is sufficient to maintain remission in FIP1L1-PDGFRA - positive CEL patients. 相似文献

Aims: Acute alcohol intoxication itself may act as a trigger for suicidal thoughts and attempts among individuals at risk and may influence the potential lethality of the suicide attempt. This study in alcohol-dependent patients compared the correlates of suicide attempts during a heavy drinking episode with those of suicide attempts during relative sobriety. Methods: In two outpatient and two residential alcohol treatment programs in Warsaw, Poland, 113 patients who reported a suicide attempt during their lifetime were interviewed. The analyses focused on the patients' most serious suicide attempts and on whether these occurred during a heavy drinking episode. Results: Over two-thirds of the patients reported that their most serious suicide attempt occurred during a period of heavy drinking. A multivariable logistic model indicated that the following factors significantly distinguished those patients whose most serious suicide attempt occurred during a heavy drinking episode: male gender, younger current age, greater severity of alcohol dependence and the attempt being unplanned. Conclusion: Among the patients in treatment for alcohol dependence who made a suicide attempt, the most serious attempt was likely to have been unplanned and committed by men when it occurred during a heavy drinking episode. 相似文献

Manganese encephalopathy is a known disorder in occupational medicine. A serious phenomenon has been the emergence of manganese encephalopathy in intravenous users of homemade methcathinone (ephedrone). A short survey was developed for clinical environments dealing with people who use psychoactive substances. The data were obtained from 72 rehabilitation therapy centers. Surveys carried out in about a third of Polish centers dealing with providing medical assistance to people addicted to substances other than alcohol and tobacco have shown that over 4% of people treated there had symptoms of manganese encephalopathy, of which more than half are people in whom the probability of a clinical diagnosis of this disorder is significant. It has been shown that knowledge of manganese encephalopathy is none or minimal in more than 70% of the surveyed institutions. An urgent need for personnel training in this field was pointed out. Attention was paid to the importance of disseminating good review articles on new and dynamically developing problem phenomena. 相似文献
