Spinal cord ischemia as intraoperatory complication in shoulder surgery positioned in beach chair: case report.

Spinal cord infarction is an uncommon phenomenon, which can be caused by different etiologies, constituting a real diagnostic challenge which can lead to devastating consequences. General anesthesia in beach chair positioning with intraoperative hypotension in order to avoid surgical bleeding are associated with hypoperfusion and potential neurological ischemia-related complications. We present a case of spinal cord ischemia in the context of shoulder surgery in a beach chair position.

Barriers for dental treatment of primary teeth in East and West Germany.

Background: In many countries, restorative treatment in primary teeth is suboptimal.

Aim: Thus, this study tried to detect barriers for dentists to restore primary teeth in kindergarten children (3-6 years).

Design: For a representative survey, 320 dentists (184 West, 136 East Germany) were randomly selected from the dental associations' registers and asked to answer a questionnaire on their profile, their view of the National Health System, and possible barriers for restoring primary teeth.

[Effects of housing conditions of farrowing and nursing sows on development of piglets: our own studies and an evaluation of the literature].

Results of rearing and growing 3250 piglets derived from 287 litters of 99 German Landrace sows in parities 1-11, from parturition throughout 5 weeks post-weaning, were compared in two farrowing systems. The Group-Farrowing System (GFS) was designed according to natural behaviour of wild pigs and contained 8 farrowing boxes allowing sows and their litters to move freely on an area of 85.2 m2.

Valsalva-induced syncope during apnea diving.

A young man had two dangerous episodes of transient loss of consciousness during apnea diving in a swimming pool. Medical and neurologic examination results were normal. Standard autonomic test results (including heart rate variability, baroreflex sensitivity, tilt-table test, and Valsalva ratio) were unremarkable, with the exception of an increased blood pressure decrease during early phase II of the Valsalva maneuver.

[Radiation-induced osteomyelitis of the mandible].

Osteoradionecrosis of the mandible following primary or adjuvant radiotherapy of progressive oral and oropharyngeal malignancy is, for the affected patient, a feared and sometimes vitally threatening complication. In the authors' experience, the incidence rate of osteoradionecrosis between 1973 and 1987 was 4.1%, which makes the necessity of the prophylactic efforts described in the present study evident.

[Diagnostic value of orthopantomography in otorhinolaryngology].

The present paper emphasizes the diagnostic importance of panoramic radiography in ENT, as demonstrated by representative groups where this specialty is indicated. Pantomographic radiography, which has proved its work in dentistry for many years, often offers a valuable alternative beyond the supplementary evidence provided by routine radiological techniques.

[Orthopantomography and its significance for the otorhinolaryngologist].

Orthopantomography, i.e. a single radiograph producing a panorama-like view of the entire jaw, was originally developed for the diagnosis of dental diseases.

[Dog bite injuries of the head and neck].

Dog bite injuries of the head and neck concern mostly children. Early definite surgical treatment provides the best cosmetic results. If necessary, detached tissue must be re-implanted and defects be closed by flap plasties.

[Clinical experiences with a standardized balanced diet in maxillo-facial surgery].

The clinical trial of a standardized balanced diet--Berodiet S--in maxillo-facial surgery during a year-period permits in regard to all aspects a fully satisfying review of this kind of tube feeding. The balanced relation of nutritive substances of biologically high value according to physiologically nutritional recommendations, a good tube passage, minimal energy of preparation and in case application by nursing personal and the practically unimportant danger of bacterial contamination in giving due regard to corresponding application notices fulfill all choosing criteria of clinical applicability of this tube feeding, which has to be evaluated also because of its individual compatibility as extremely positive and extensively free of secondary effects within the bounds of physiological requirements.

[Hypertrophy of the masseter: aetiology, diagnosis and treatment (author's transl)].

An assessment of the pathogenesis of masseter muscle hypertrophy is first discussed. This is followed by an account of its diagnostic criteria and by a consideration of the differential diagnosis. General instructions regarding its treatment are presented.

[ Glucose concentration in blood during exertion. 5. Use of the total distribution of blood glucose values during physical exercise or the estimation of response to exertion in various breeds of swine].

Blood glucose was determined by an enzymic method in 56 pigs of the German Edelschwein, German Landrace, German Saddleback breeds and Edelschwein/Landrace crosses before, during and after exercise on a belt moving at 1.3 metres/second for ten minutes, at 10 degrees C (winter) or 22-34 degrees C (summer) and relative humidity of 65-75%. Total plasma glucose was calculated from the plasma volume.

[Evaluation of blood glucose concentration during exertion. 6. Effect of anemia on the glucose regulation capacity of domestic swine in standardized running exercise].

Individual mean blood glucose values and the scatter of individual values were determined in six healthy and six anaemic pigs before, during and after ten minutes of exercise on a belt moving at 78 m/min (environmental temperature 22-24 degrees C, relative humidity 55-65%). The glucose regulatory capacity of anaemic pigs was inferior to that of healthy pigs. Blood glucose regulation was related to haemoglobin content and to the increase in rectal temperature during exercise.
