A field study was carried out among cold store workers in China. A self administrative questionnaire and health check-up were taken among 463 male workers from two different types of cold stores, all during their whole daily work. 296 men from Lower Temperature Stores (LTS), where the air temperature was between -10 to -25 degrees C, and 167 men from Ice Stores (IS), where the air temperature was between -5 and +5 degrees C participated. Another group of 152 men working in normal stores and exposed to an air temperature between 20 and 30 degrees C served as a control group. The study did not indicate any special disease attributable to the cold environment. The number of complaints of lower back pain and knee pain in the cold exposed group were significantly higher than that of the control group (in LTS: 42.3%, 46.6%; IS: 52.7%, 50.8%; control group: 9.2%, 14.5%; low back and knee pain, respectively). After 5 years of cold exposure work, the lower back and knee symptoms were very frequent. The point press pain on the knees of the cooler group (LTS) was higher than in the moderate cold group (IS). We suppose that the cold factor contributed to lower back and knee pain. 12.2% of 463 cold exposed workers had frostbite on the body extremities viz: hand, foot and ear. Self estimation of health indicated more problems among cold exposed workers (28.0%) than control group (2.7%).

Ten patients with debilitating hip or knee pain were examined with magnetic resonance (MR) imaging. All had conventional radiographs that were either normal or showed nonspecific osteopenia. Nine patients had bone scintigrams that showed focal increased radionuclide uptake in the region of the painful joint. In each case, MR images of the affected joint showed regional decreased signal intensity of the bone marrow on T1-weighted images and increased signal intensity on T2-weighted images. Biopsy results of four patients excluded ischemic necrosis and metastases. The symptoms resolved spontaneously in all cases. The ten patients were followed up for 12-36 months, and there were no recurrences. The authors believe that the findings on MR images represent a transient increase in bone marrow water content. The focal findings on scintigrams confirmed the periarticular distribution of the process and provided evidence of accompanying hyperemia and increased bone mineral metabolism. For lack of a better term and to emphasize the generic character of the condition, the authors termed this condition "the transient marrow edema syndrome."

Seventy-seven subjects were decompressed from air or nitrogen-oxygen (nitrox) saturation exposures at 18.3 to 40.2 meters sea water (msw) [60 to 132 feet sea water (fsw)] using four different decompression schedules. A h schedule for decompression from an air saturation-excursion profile at 18.3 msw (60 fsw) resulted in pain-only decompression sickness (DCS) symptoms in 2 of 23 subjects. A 32 and 35 h schedule from a different air saturation profile at 19.8 and 22.9 msw (65 and 75 fsw), respectively, resulted in DCS symptoms in 1 of 24 subjects. A third and fourth schedule for air or nitrox saturation at 40.2 msw (132 fsw) resulted in DCS symptoms in 3 of 12 and 1 of 18, respectively. No serious (type II) symptoms were observed as a result of any of the decompressions. All DCS cases consisted of knee pain occurring either in the last 3 msw of the decompression or shortly after surfacing. Doppler ultrasound monitoring revealed venous gas emboli (VGE) in several subjects, but generally only shallow to 6.1 msw (20 fsw). Results demonstrate an overall DCS incidence of 9%, and all cases were pain-only and localized to the knee. The third schedule (U.S. Navy heliox saturation decompression schedule) seems to produce a higher incidence of DCS than the other schedules when used in air or nitrox exposures. Differentiation between the schedules designed for nitrox was impossible due to the limited number of subjects in each and the variable nature of the exposures.

From April 1993 to December 1993, we prospectively studied the knees of 15 patients (mean age, 48 +/- 11 yr) receiving long-term hemodialysis (mean duration, 9 +/- 4 yr) using magnetic resonance imaging (MRI) techniques including, T1 weighted spin-echo, multiplanar gradient recalled, and postcontrast T1 with chemical shift-selective, fat-saturation pulse sequences. Analysis of these images revealed that the three findings most indicative of hemodialysis-related arthropathy were intramedullary, cortical and soft tissue lesions. Knee pain was significantly correlated with the presence of soft tissue lesions. Cortical lesions were usually associated with soft tissue lesions. Inflammatory changes adjacent to soft tissue lesions were demonstrated in postcontrast studies in all patients with soft tissue lesions. Increases in water content in those lesions appeared to increase the signal intensity. Our results indicate that MRI is useful in demonstrating the extent of hemodialysis-related arthropathy involvement, especially in hemodialysis patients suffering from knee pain.

Previous studies note a positive relationship between female-headed households (FHHs) and poverty in urban and rural areas of Botswana. To explore this further, data were collected from 7 FHHs through participant observation and open-ended interviews. A secondary analysis of data described the quality of life (QOL) of members of the households according to one's ability to meet basic human needs (food, water, shelter, safety, and health). FHHs ranged in age from 40-91 years, with family size ranging from 1-11 members. Monthly income for 6 of the 7 families was 30 dollars (U.S.) per month or less. Physical living environments were overcrowded, with poorly maintained latrines and unsafe refuse disposal. Family illnesses included hypertension, cataracts, mental illness, knee pain, ringworm, leg sores, and tonsillitis. Health risk behaviours included unprotected sex, alcohol abuse, and breastfeeding among potentially HIV positive mothers. Although Botswana claims rapidly rising levels of national income after independence, the QOL of FHHs remains poor. We suggest that, to alleviate poverty, governments in developing African countries should explore strategies that effectively target families headed by women.

Hyaluronic acid (HA) is a glycosaminoglycan composed of alternating N-acetyl-D-glucosamine and D-glucuronic acid moieties. HA is an ubiquitous component of connective tissue where it forms matrix and plays an important role in the maintenance of matrix structure and water balance. The viscoelastic properties of HA derivatives and nonimmunogenicity has provided its use in a number of pharmaceutical applications. Ability of HA to create and fill space by organizing and modifying the extracellular matrix is widely used for soft tissue augmentation to limit age-related and photoinduced skin aging, but also may be used for correction of facial lipodystrophy and to prevent reccurence of hypertrophic scars or keloids. Furthermore HA may be employed as a surgical aid in ophthalmology or to reduce knee pain and joint motion in patients with osteoarthritis. In children HA may become an alternative to the open surgery for the management of vesicoureteral reflux.

Rowing-whether on the water or with machines-is increasingly popular, and, as with any strenuous exercise, the potential for injury is high. Rowers may have common symptoms, such as low-back and knee pain, or more sport-specific problems such as rib stress fractures, nerve impingement, and blisters. Virtually all rowing injuries are due to overuse, and many can be traced to training errors or equipment problems. Understanding the mechanics of rowing, the equipment, and the training procedures is essential for the physician caring for injured rowers.

The authors describe a case of distal femoral physeal injury with disruption of the perichondrium in a 9-year-old girl after a sledding accident. The patient presented with knee pain, limited range of motion, and inability to bear weight. Initial radiographs were normal. A magnetic resonance imaging of the knee demonstrated abnormal signal and widening of the distal femoral physis with elevation of the posterior distal femoral periosteum. This case illustrates the main magnetic resonance imaging findings in an occult Salter Harris type I injury: increased physeal thickness and signal intensity on water-sensitive sequences, perichondrial disruption, and intracartilaginous fracture.

Competitive swimmers are affected by several musculoskeletal and medical complaints that are unique to the sport. 'Swimmer's shoulder,' the most common overuse injury, is usually caused by some combination of impingement, rotator cuff tendinopathy, scapular dyskinesis, and instability. The condition may be treated with training modifications, stroke error correction, and strengthening exercises targeting the rotator cuff, scapular stabilizers, and core. Implementation of prevention programs to reduce the prevalence of shoulder pathology is crucial. Knee pain usually results from the breaststroke kick in swimmers, and the 'egg beater' kick in water polo players and synchronized swimmers. Lumbar back pain also is common in aquatics athletes. Among the medical conditions of particular importance in swimmers are exercise-induced bronchoconstriction, respiratory illnesses, and ear problems. Participants in other aquatics sports (water polo, diving, synchronized swimming, and open water swimming) may experience medical ailments specific to the sport.

The aim of this study was to estimate the effects of pressurized salt ice packs (PIP) with water ice packs (WIP) which are used to relieve pain and decrease swelling on patients following total knee arthroplasty (TKA). Sixty-nine patients undergoing primary unilateral TKA were randomly divided into two groups (PIP group and WIP group). We used a visual analog scale (VAS) to score knee pain and the score was recorded. The knee bilateral girth, the slipping times of the ice pack, and the times of wound dressing or bed moist were recorded during cryotherapy. The scores of pain between the two groups were significant difference in 12 h, 24 h, 48 h and 72 h after TKA (P < 0.05). No significant difference was found for the girth measurements of the operative knee on the two levels in 12 h, 24 h and 72 h, respectively. However, there was statistically difference for girth measurements between the two groups in 48 h after TKA (P < 0.05). PIP is a cheap, safe and simple method, which is more effective than WIP on reducing pain and swelling degree of patients. Thus, PIP is recommended in clinical nursing work.
