[Impingement syndrome of the subacromial area: analysis of 42 cases].

To create a new classification of subacromial impingement phenomena according to different etiology, we treated 42 cases of impingement syndrome. They were 29 male, and 23 females, with an average age of 45 years. 29 patients had typical subacromial pain are signs. Positive impingement test was found in 30 patients. Roentgenographic findings showed that the high density of the great tuberosity (GT) in 27 cases, 8 cases got the cystic changes around the CT, and exostosis formed on the G. T. in 3 cases. The abnormal acromion with sloped or over hanging form was found in 6 cases. 11 cases had an irregular inferior surface of the acromion in two cases with the spur formed at inferior surface of acromion. Four patients combined with calcium deposit at subacromial space. Space narrowing of the AH interval was in noted 12 cases. According to the X-ray findings, 35 cases were classified into the abnormal anatomy structure group. The other 7 patients were in dynamic impingement group. 13 cases of impingement syndrome combined with the complication of rotator cuff tear were treated by the Mclaughlin's procedure for repairing the rotator cuff with the acromion plasty. 11 patients were followed up for more than 6 months after operation. 7 cases had excellent results and 4 cases good results. This classification includes two kinds of impingement syndromes: anatomical of structural and dynamic or dysfunction.

[Early cancer detection in the oro-pharyngo-laryngeal area: analysis of a regional screening project (author's transl)].

During a six months lasting screening project 6866 persons were examined free of cost. Inspection of the mouth, endoscopy of the naso-hypopharynx and larynx with the Wolf-endoscope after v. Stuckrad, and palpation of the neck were included. Every sixth person required further diagnosis or treatment. Precanceroses were found in almost 3%, and up to now malignomas were found in 0.3% of the screened persons. Among these 14 cases of cancer were 9 carcinomas of the larynx. This comparatively high percentage of precanceroses and cancer favors the endoscopic screening of patients with organ-related symptoms and of high risk groups.

[Failure of the central oxygen supply to a surgical area. Analysis of a critical incident].

An incident involving central oxygen supply failure affecting 4 anesthetized patients in the operating theatre was analyzed by way of interviews with the anesthesiologists and a review of graphic records of anesthesia. The 4 ventilators involved had been checked by each anesthesiologist according to his own method. The oxygen supply failure alarm warned of the supply cutoff in 2 cases and the oxygen analyzer detected the other 2 within approximately 1 minute. After the failure, 2 patients were ventilated with ambient air through the ventilator, 1 was given medicinal air with the resuscitator. None suffered damage or recalled having awakened as a result of the incident. The cause of the failure in oxygen supply has not been determined but its duration has been estimated to be between 4 and 7 minutes. Our investigation shows that: 1) the operating rooms are not equipped with an alarm that warns of a drop in pressure within the tubes that supply central oxygen and in 2 cases the alarm warning of a cutoff in oxygen supply to the respirator did not sound correctly; 2) the ventilator equipment check did not follow a standard method and did not cover the possibility of oxygen supply failure, and 3) no alternative oxygen supply is available inside the operating theatre.(ABSTRACT TRUNCATED AT 250 WORDS)

Long-term effect on optic nerve of silicone oil tamponade in rabbits: histological and EDXA findings.

PURPOSE: Side-effects after intravitreal use of silicone oil (SO) are not well defined and elucidated. The object of this study was to examine the influence and toxicity of SO on the optic nerve after vitrectomy with SO tamponade. METHODS: We injected medical grade SO and emulsified SO into rabbit eyes after gas-mediated vitreous compression and examined the eyes by light microscopy (LM), transmission electron microscopy (TEM) and energy dispersive X-ray analysis (EDXA) (point analysis and area analysis) 6 months after injection. We compared the findings in the non-treated eyes and eyes with only gas-mediated vitreous compression with those in SO-injected eyes. RESULTS: Vacuole-like structures were seen in the optic nerve posterior to the lamina cribrosa. In the group treated with only gas-mediated vitreous compression, the myelin structures were shown by TEM to be destroyed and replaced by glial tissue, while in groups injected with medical grade or emulsified SO severe destruction of the myelin sheath (myelinolysis) was observed. Silicone was identified at the electron-dense edges of the vacuoles by EDXA point analysis, but not in the vacuoles without electron-dense deposits. Dots of Si K alpha were not seen in the control groups, and dense dots were observed in SO-injected groups, by EDXA area analysis. CONCLUSIONS: Some of the vacuoles might be artefacts caused by insufficient fixation or the operative procedure, but TEM showed almost no artefacts in the control optic nerve. Thus, most vacuoles may be SO storage sites. SO uptake into the optic nerve might play a role in the pathogenesis of optic nerve atrophy after SO injection.

Small area variation analysis: a tool for primary care research.

Small area variation analysis is a research tool used by health services researchers to describe how rates of health care use and events vary over well-defined geographic areas. Significant variation has been shown to exist in the rates of hospitalization for chronic obstructive lung disease, pneumonia, hypertension, and in surgical procedures, such as hysterectomy, cholecystectomy, and tonsillectomy. Potential sources of variation include differences in underlying morbidity, access to care, physician judgment, quality of care delivered, patient demand for services, and random variation. Small area variation studies have been used to determine if significant variation exists across geographic areas and to describe relationships between the observed variation and potential causal factors. Methodologic concerns include the definition of small areas, defining the at-risk population within each small area, sample size, case mix adjustments, and stability of rates over time. The use of small area analysis in primary care will require definition of appropriate small areas for ambulatory care, description of the variation in ambulatory events across small areas, development of appropriate measures for ambulatory case mix, and development of appropriate tools to measure the outcomes of ambulatory care.

Potential use of small area variations analysis in nursing outcomes research.

Small area variations analysis (SAVA) is a method for measuring and analyzing differences in clinical practice and service utilization across small geographic areas. To date, nursing has not adopted a SAVA approach in patient outcomes studies. A discussion is offered of the conceptual and methodological considerations confronting researchers and outcomes managers who wish to conduct a small area variations analysis followed by examples and suggestions for incorporating SAVA into nursing practice.

Seasonal variation in orthopedic health services utilization in Switzerland: the impact of winter sport tourism.

BACKGROUND: Climate- or holiday-related seasonality in hospital admission rates is well known for many diseases. However, little research has addressed the impact of tourism on seasonality in admission rates. We therefore investigated the influence of tourism on emergency admission rates in Switzerland, where winter and summer leisure sport activities in large mountain regions can generate orthopedic injuries. METHODS: Using small area analysis, orthopedic hospital service areas (HSAo) were evaluated for seasonality in emergency admission rates. Winter sport areas were defined using guest bed accommodation rate patterns of guest houses and hotels located above 1000 meters altitude that show clear winter and summer peak seasons. Emergency admissions (years 2000-2002, n = 135'460) of local and nonlocal HSAo residents were evaluated. HSAo were grouped according to their area type (regular or winter sport area) and monthly analyses of admission rates were performed. RESULTS: Of HSAo within the defined winter sport areas 70.8% show a seasonal, summer-winter peak hospital admission rate pattern and only 1 HSAo outside the defined winter sport areas shows such a pattern. Seasonal hospital admission rates in HSAo in winter sport areas can be up to 4 times higher in winter than the intermediate seasons, and they are almost entirely due to admissions of nonlocal residents. These nonlocal residents are in general -and especially in winter- younger than local residents, and nonlocal residents have a shorter length of stay in winter sport than in regular areas. The overall geographic distribution of nonlocal residents admitted for emergencies shows highest rates during the winter as well as the summer in the winter sport areas. CONCLUSION: Small area analysis using orthopedic hospital service areas is a reliable method for the evaluation of seasonality in hospital admission rates. In Switzerland, HSAo defined as winter sport areas show a clear seasonal fluctuation in admission rates of only nonlocal residents, whereas HSAo defined as regular, non-winter sport areas do not show such seasonality. We conclude that leisure sport, and especially ski/snowboard tourism demands great flexibility in hospital beds, staff and resource planning in these areas.
