An effective method of skin traction in A-K guillotine amputation.

In modern orthopedic surgery, there are still indications for the guillotine amputation of the thigh. Immediate postoperative management by effective skin traction can promote rapid healing and eliminate the need for revision surgery. Revision surgery necessitates further shortening of the stump; skin grafting likewise can be avoided as a secondary procedure. Most skin tractions for above-the-knee amputations loosen within 24 hours. The suggested method of applying skin traction on A-K amputations, if applied properly, will be effective for periods ranging from five to seven days.

Myocutaneous flaps: the Saskatoon experience.

The purpose of this study was to determine the results of myocutaneous flap procedures performed in three Saskatoon hospitals between 1977 and 1979. Twenty-two flap procedures were performed on 17 patients. Eleven patients were suffering from decubitus ulcers and 6 had other wounds. Myocutaneous flaps have a place in the early surgical management of decubitus ulcers. Fluorescein given intravenously in some patients during operation was used to assess flap viability; 4 out of 10 flaps required trimming as a result. The myocutaneous flap technique provides rapid and durable closure for a wide variety of tissue defects which are otherwise difficult to cover.

A distinctive variant of pernio. Clinical and histopathologic study of nine cases.

We describe here nine women who had similar distinctive clinical features that consisted of painful red-to-purple macules, papules, and plaques on the digits, predominantly on the toes. All patients reported that exposure to cold had preceded their symptoms. Histologic study demonstrated a lymphocytic vasculitis, characterized by lymphocytes infiltrating the walls of blood vessels in eight (88%) of nine lesions. This pattern of inflammation is different from the perivascular lymphocytic infiltrate that is common to lupus erythematosus, erythema multiforme, lymphocytic infiltration of the skin (Jessner), and drug eruptions. It also serves to distinguish the disorder from other clinical conditions resembling it, such as cellulitis, herpes simplex infection, and disseminated gonococcemia. To the best of our knowledge, this lymphocytic vasculitis has not been previously described as occurring in pernio. We believe the unique disorder that we are reporting is a common, but infrequently recognized, variant of pernio.

[Thermal stress. Dangers, tolerance, prevention and cure].

The Authors after a description about the thermoregulation processes and after having considered the tolerance of the human body to the thermic stress, point out the dangers of the exposure to the high or low temperatures in some labour conditions and, in particular; in the aerospace ambient. A great importance is attached to the method of prediction of individual tolerance to varied temperatures. Lastly the Authors discuss the prevention and treatment of heat-stroke and of frost-bite.

Diagnosis from single-digit radiography.

This pictorial assay illustrates the value of plain radiographs of the digit in diagnosing disease in children. Although the hand is regarded as a mirror of disease, the finger often points to the correct diagnosis. The authors present a series of cases for which a coned-down view of a single digit is given. In some cases the findings indicate a specific diagnosis, whereas in others only a differential diagnosis is possible. The radiographic findings and a brief differential diagnosis, as well as the definitive diagnosis, are presented for each case.

Psychological and psychophysiological factors in prevention and treatment of cold injuries.

Cold injured patients in Alaska come from many sources. Although sport and work continues to provide large numbers of cold injured, most severe repeat injuries tend to reflect other biopsychosocial consequences. Certain behaviors can increase the probability of injury, however all persons living in cold climates are potential candidates. One can decrease risk by education, knowledge and intelligent behavior. Proper respect for adequate protection and hydration seem to be critical factors. Understanding the psychological, physiological and psychophysiological aspects of the cold environment performer helps refine the prevention and treatment strategies for cold injury. Skill training with bio-behavioral methods, such as thermal biofeedback, and the value of medical psychotherapy appear to offer continued promise by facilitating physiologic recovery from injury, as well as assisting in long term rehabilitation. Both approaches increase the likelihood of a favorable healing response by soliciting active patient participation. Medical Psychotherapy for traumatic injuries can also help identify and manage cognitive emotional issues for families and patients faced with the permanent consequences of severe thermal injuries. Thermal biofeedback therapy has the potential benefit of encouraging greater self-reliance and responsibility for self-regulating overall health by integrating self-management skills regarding physiology, diet and lifestyle. Inpatient and outpatient biofeedback training offers specific influence over vascular responses for healing, as well as providing an effective tool for pain management. Interest in cold region habitation has continued to expand our study of human tolerance to harsh, extreme environments. Biological, psychological, sociological, and anthropological views on adaptation, habituation, acclimatization, and injury in cold environments acknowledges the role of development, learning and educated responses to cold environments. The study of health, performance, and injury prevention in extreme isolated cold environments has important strategic and scientific implications. What is learned from behavioral studies of cold survival provides an opportunity to increase our scientific knowledge and understanding. These cold research findings can assist in our future exploration of cold, underwater farming at great depths, and to far distance space travel to cold planets. The relatively new research frontier "Polar Psychology" has evolved to study how interactions with cold environments can have both positive and/or negative consequences. This research simulates the psychological factors likely to be encountered while exploring isolated cold regions of distant galaxies. The psychological and psychophysiological correlates of cold experience appear to be a function of four interactive issues: the environment, genetic predisposition, learning or experience, and finally perception or cognition. Individual cold tolerance seems to relate heavily on sensation, perception and behavior.(ABSTRACT TRUNCATED AT 400 WORDS)
