Role of the health care supervisor in management of a therapeutic milieu.

The health care supervisor responsible for establishing a therapeutic milieu within a traditional hospital organization will have greater success if these suggested management strategies are employed. Decentralizing, improving organizational communication, and clarifying interdisciplinary role relationships are the strategies that support the integration of differing organizational approaches to management.     

Studies of the blood lipid peroxide status and vitamin E levels in patients with chronic active hepatitis and alcoholic liver disease

As free radicals and lipid peroxidation are involved in the pathogenesis of different inflammatory diseases of the liver, the blood malondialdehyde content, the activity or quantity of free radical eliminating enzymes and the natural antioxidant, vitamin E serum level has been studied in ten patients with chronic active hepatitis and in six subjects with alcoholic liver disease. Thirty healthy volunteers served as controls. The serum malondialdehyde/thiobarbituric acid reactive substance and its concentrations increased significantly in both hepatitis groups. The superoxide dismutase content was also raised in the patients' sera. The serum glutathione peroxidase (GSH-Px) activity was decreased in both groups, while the red blood cell GSH-Px showed a significantly lower activity in the alcoholic hepatitis patients. Serum catalase activity and vitamin E levels in both types of chronic hepatitis were not significantly different from the healthy controls.     

Comparative analysis of the effect of gestagens,antiestrogencytostatics, and androstenes on the viability of tumor and normal cells

The hormonal compound with the highest cytostatic activity against MCF-7 tumor cells (human breast cancer, BC) and the lowest activity against normal cells (rat skin fibroblasts) was sought among gestagens, androstenes, and antiestrogencytostatics. It was found that antiestrogencytostatics and androstenes had the highest cytostatic activity against tumor cells whereas gestagens and antiestrogencytostatics were least active against fibroblasts. Studies of the activity of the hormonal compounds in combination with doxorubicin on the viability of MCF-7 and rat skin fibroblasts found that all investigated compounds with the exception of dehydroepiandrosterone (DHEA) intensify the cytostatic activity of doxorubicin against tumor cells, the greatest effect seen for antiestrogencytostatics. A chemoprotective effect of androstenes on normal cells was noted. __________ Translated from Khimiko-Farmatsevticheskii Zhurnal, Vol. 41, No. 7, pp. 3–7, July, 2007.     

Preference for donor site scar orientation in pedicled latissimus dorsi breast reconstruction

A survey was carried out to ascertain the preference for donor site scar orientation in patients undergoing pedicled latissimus dorsi breast reconstruction and their views on breast reconstruction in general. One hundred twelve women (59 Chinese, 53 Western) completed the questionnaire. Participants were asked to state their preferred scar orientation (i.e., oblique, horizontal, or vertical) based on photographs showing the position of the scars. Demographic information and views on issues surrounding breast reconstruction in general were also collected. Data was analyzed non-parametrically with chi-square test and t test. The mean age of participants was 39.5 years (20–73 years). Seventy-seven percent of the participants would opt for an immediate breast reconstruction if offered (p < 0.001). Eighty-six percent would have objection to the use of silicone implant as a whole or part of a reconstruction (p < 0.001). Vertical and horizontal scars were the preferred orientation, with no women choosing the oblique orientation as their first choice (p < 0.001). The non-Chinese of 40 years or older, as well as Chinese women from all age groups, preferred the horizontal scar (p < 0.05). We demonstrated that both culture and age impact on the preferred scar orientation in breast reconstruction. Women in the age group we commonly reconstruct favored the horizontal scar. However, the younger women of non-Chinese origin tended to favor the vertical scar.
