Both conservative and operative forms of treatment have been recommended for patients with a 'floating shoulder'. We compared the results of conservative and operative treatment in 25 patients with this injury and investigated the use of the glenopolar angle (GPA) as an indicator of the functional outcome. A total of 13 patients (ten male and three female; mean age 32.5 years (24.7 to 40.4)) were treated conservatively and 12 patients (ten male and two female; mean age 33.67 years (24.6 to 42.7)) were treated operatively by fixation of the clavicular fracture alone. Outcome was assessed using the Herscovici score, which was also related to changes in the GPA at one year post-operatively. The mean Herscovici score was significantly better three months and two years after the injury in the operative group (p < 0.001 and p = 0.003, respectively). There was a negative correlation between the change in GPA and the Herscovici score at two years follow-up in both the conservative and operative groups, but neither were statistically significant (r = -0.295 and r = -0.19, respectively). There was a significant difference between the pre- and post-operative GPA in the operative group (p = 0.017). When compared with conservative treatment, fixation of the clavicle alone gives better results in the treatment of patients with a floating shoulder. The GPA changes significantly with fixation of clavicle alone but there is no significant correlation between the pre-injury GPA and the final clinical outcome in these patients.

Background. Malnutrition is common in patients with chronic renal failure (CRF), and its prevalence before the initiation of dialysis is poorly characterized in these patients in developing countries. There is a paucity of data on the quantification of malnutrition and inflammation in undialyzed patients of CRF from India. This study analyzed the prevalence and causes of malnutrition in patients with CRF before the initiation of dialysis treatment. Material and Methods. In the present study, assessments of nutritional and inflammatory status were carried out in patients with CRF. Serum albumin, body mass index (BMI), triceps skin fold thickness (TST), mid-arm muscle circumference (MAMC), and subjective global assessment (SGA) scoring were used for assessment of nutritional parameters. Serum C-reactive protein and serum ferritin level were used to assess the inflammatory state of the patient. Results. Two hundred and three (146 male, 57 female) patients with CRF were included in the study from August 2004 to April 2006. Overall, the prevalence of malnutrition was 65% (131/203). The age of malnourished patients (93 male, 38 female) ranged from 11-82, with mean age of 52 ± 12.68 years. The mean serum total protein and albumin were also significantly lower in patients with malnutrition in comparison to non malnourished cases (5.50 ± 0.40 gm/dL vs. 5.74 ± 0.38 gm/dL; p < 0.05, and 3.18 ± 0.58 gm/dL vs. 3.68 ± 0.55 gm/dL; p < 0.05). The C-reactive protein and serum ferritin were significantly elevated in the malnourished group as compared to non-malnourished patients (63% vs. 33%; p < 0.05, and 301.2 ± 127.1 mg/dL vs. 212.7 ± 124.9 mg/dL; p < 0.05). Conclusion. Thus, malnutrition was common in patients with CRF before the commencement of dialysis. These data indicate that an emphasis should be placed on the assessment and prevention or correction of malnutrition in patients with CRF because of its documented adverse effect on the outcome on maintenance dialysis.

Evidence indicates that stress conditions might lead to drug dependence. Recently, we have demonstrated that exposure to far infrared ray (FIR) attenuates acute restraint stress via induction of glutathione peroxidase-1 (GPx-1) gene. We investigated whether FIR affects methamphetamine (MA)-induced behavioral sensitization and whether FIR-mediated pharmacological activity requires interaction between dopamine receptor and GPx-1 gene. We observed that MA treatment significantly increased GPx-1 expression in the striatum of wild-type (WT) mice. Interestingly, exposure to FIR potentiated MA-induced increase in GPx-1 expression. This phenomenon was also observed in animals receiving MA with dopamine D1 receptor antagonist SCH23390. However, dopamine D2 receptor antagonist sulpiride did not affect MA-induced GPx-1 expression. FIR exposure or SCH23390, but not sulpiride, significantly attenuated MA-induced behavioral sensitization. Exposure to FIR significantly attenuated MA-induced dopamine D1 receptor expression, c-Fos induction and oxidative burdens. FIR-mediated antioxidant effects were also more pronounced in mitochondrial- than cytosolic-fraction. In addition, FIR significantly attenuated against MA-induced changes in mitochondrial superoxide dismutase and mitochondrial GPx activities, mitochondrial transmembrane potential, intramitochondrial Ca level, mitochondrial complex-I activity, and mitochondrial oxidative burdens. The attenuation by FIR was paralleled that by SCH23390. Effects of FIR or SCH23390 were more sensitive to GPx-1 KO than WT mice, while SCH23390 treatment did not exhibit any additive effects on the protective activity mediated by FIR, indicating that dopamine D1 receptor constitutes a molecular target of FIR. Our result suggests that exposure to FIR ameliorates MA-induced behavioral sensitization via possible interaction between dopamine D1 receptor and GPx-1 gene.
