Between the state of well-being and that of illness, an intermediary state often occurs, characterized by feelings of uneasiness, fatigue and pains. The study of these intermediary states in function of the work load (posture, noises, heat, etc.) constitutes an important feature of ergonomics. In this study we present the results of two polls showing pains due to inappropriate postures. Many observations of occupational medicine lead us to believe that pathological troubles of rheumatic order (arthritis, periathritis, tendinitis, myalgias, arthroses) can appear as a result of inappropriate postures and repetitive movements over a number of years. Thus, the ergonomic analysis of the work place can help to determine the risk of illness.

The histochemical characteristics, cross-sectional area and capillary of the skeletal muscle fibers of the anterior and posterior regions of the superficial masseter and the temporalis muscles are described for juvenile and adult rhesus monkeys of both sexes. Slow twitch fatigue resistant (S), fast twitch fatigue resistant (FR) and fast twitch fatigable (FF) fibers were found in varying proportions throughout the muscles; however some fibers with an intermediate myofibrillar ATPase activity were observed in the anterior masseter. No significant differences for any of the variables were found between male and female juveniles for a specific muscle sample site. However, considerable variation was found between juvenile and adult and between adult male and female monkeys in the percentages of different fiber types and the cross-sectional area of fibers in specific regions of the superficial masseter and temporalis muscles. We conclude from these observations that significant differences in function exist both within and between the different masticatory muscles of rhesus monkeys. Functional differences may result from the pronounced sexual dimorphism evident in the dentofacial complex of the rhesus monkey.

For the past eight years the Rochester Child Health Group has systematically investigated chronic illness in childhood with the goal of minimizing the psychosocial sequelae of chronic illness through more optimal management. This overview examines the impact of chronic illness on 404 children and their families in five separate studies: 1) 209 children in a follow-up of all children with chronic symptoms in a previous random sampling of children; 2) 42 children with juvenile arthritis; 3) 44 nephrotic children; 4) 54 asthmatic children; 5) 55 chronically ill children living in rural areas of Western New York. Information was obtained through parental interviews, school reports, and psychological testing of the child. The percentage of parents reporting impact of the child's illness on family differed according to study population. The percentage reporting areas of impact according to severity of the illness is as follows: worry, 75--97; financial, 46--60; fatigue of parent, 31--65; change in sleep arrangements, 17--31; change in furnishings, 15--40; less social life for parents, 12--35; restrictions on travel, 13--40; parental friction, 9--20; sibling neglect, 10--20; sibling resentment, 10--25; embarrassment, 12--20; interference from relatives, 5--17. Over half the parents felt their child's future education, job chances, and social life would be affected. One third reported activity limitations. Compared to a control group of children, a significantly greater percentage of parents of the chronically ill reported teacher concern about their child's effort and behavior, and showed concern about the child having too few friends. Two of the three studies in which psychological appraisals were obtained suggested that more of the ill children than controls showed indices of maladjustment. School information from two studies showed more of the ill children than controls underachieving and being referred to a school psychologist. Work by the Rochester Child Health Group has pointed up several ways in which providers of care can more optimally assist families in order to minimize these problems: 1) identifying families at risk at the onset to find which families may require special support; 2) Assuring that family and all care providers know who is orchestrating care, and that all areas of care are being provided; 3) Assuring that where necessary, an outreach person is meeting the needs of the family and child on an intensive, sustained, caring and creative basis.

Workups by physicians in response to five common complaints in a sample of 104 men and women--52 married couples--were evaluated by chart audit. For the total group of complaints, back pain, headache, dizziness, chest pain, and fatigue, the physicians' workups were significantly more extensive for men than they were for women. These data tend to support the argument that male physicians take medical illness more seriously in men than in women.

The anterior cruciate ligaments in 17 knees of 12 mongrel dogs were replaced with one of three porous minimally reactive prosthetic (synthetic) materials. The results show that while the porous materials support the ingrowth of fibrous tissue from the bone of the dog's knee, fatigue failure occurred before sufficient fibrous tissue was incorporated to reconstitute a functional ligament. Further laboratory investigation is necessary before prosthetic materials, currently available, can be used in the unstable human knee.

Basing on roentgenological observation of the course of the disease, and on postmortem examination, of a patient with polysegmental Andersson lesions (known as spondylodiscitis) in ankylosing spondylitis, the article reports on the histological and often also clinico-roentgenological possibility of differentiating between an inflammatory and non-inflammatory type of this destructive lesion. The non-inflammatory type of Andersson lesion reflects a fracture due to fatigue, or its sequel, eg pseudarthrosis, in the stiffened axial skeleton. In this particular patient, renal osteopathy had favoured the genesis of the disease.

Materials in current use resulting from clinical acceptance are reviewed. Requirements for a bio-material are considered and problem areas still awaiting solution are identified. These include fatigue, wear, corrosion and adverse tissue effects. The question of relating the structure of materials to their in-vivo properties and the application of this to development of bio-materials is next considered. The properties of the tissues and the way in which newer materials are better adapted to the dynamic properties of these is discussed and future developments are considered in the light of this.

Amongst approximately 1 500 spastic children under treatment, the authors have seen three cases of fatigue fracture of the patella. One patient was spastic and two others were athetotic. The fatigue fractures can be explained by a flexed knee gait aggravated by a contracture of the hamstring tendons. No fracture was seen in patients treated by Egger's operation. It is concluded that this procedure both prevents and cures fatigue fracture of the patella.

A 26-year-old female with Bartter's syndrome associated with Graves' disease is reported. This patient had a history of Graves' disease from the age of 22 and anti-thyroid drug (Methimazole) had been administered for 2 years. Thyroid function returned to normal but general fatigue and polyuria continued. Hypokalemia was diagnosed at 25 years of age and she was referred to our hospital for evaluation. Blood pressure was normal and laboratory data revealed normal thyroid function, hypokalemic alkalosis, high plasma renin activity and high plasma aldosterone concentration. She showed normal pressor sensitivity to norepinephrine infusion, grossly diminished pressor sensitivity to exogenous angiotensin II infusion compared with the normal. A renal biopsy specimen showed juxtaglomerular cell hyperplasia. Electron microscopy confirmed lacis cell (agranular cell) proliferation.

The 1976 Olympiad for the Physically Disabled was the first olympiad with full competition for blind, paralyzed, and amputee athletes. More than 1,500 from 38 countries took part in wheelchair (12 events), blind (8 events), and amputee (11 events) games. Participants were classified by an international team of doctors. The athletes were accomodated in university residences with small infirmaries. A school near the games site was used as a field hospital. Rest areas were also set up. Volunteers served on the medical staff (three doctors, three nurses, three receptionists, and three physical therapists on each of two shifts per day). In addition doctors, nurses, trainers, and physical therapists rotated around various venues at the games site. Physicians treated 285 patients (184 were athletes; others were spectators) for a variety of problems, physical therapists treated 119 athletes, and trainers treated 114 athletes. Contigency plans in case of mass disaster were made but were not needed. Disabled athletes are slightly more vulnerable to stress and fatigue than able-bodied athletes. The Toronto games will probably be remembered as the turning point in the emergence of sports for the disabled from a purely rehabilitation measure to a true sporting event in its own right.
