Marfan's syndrome is a hereditary disorder of connective tissue, involving the ophthalmic, cardiovascular and musculoskeletal systems. Two cases are described in which protrusio acetabuli was a major problem. Otto pelvis should be considered as one of the musculoskeletal manifestations of Marfan's syndrome.
A study was conducted to determine the validity of the MMPI for 142 American Indian patients from Pacific Northwest tribes. All the MMPI profiles were similar and had significant elevations in the Sc, Pd, and Pa scales. There was no significant difference between diagnostic groups on many clinical scales. Nonpsychotic, depressed Indian patients could not be distinguished from schizophrenic patients on any clinical scale, and there were no significant differences between antisocial-alcoholic patients and those with situational reactions. There were minimal differences between the Northwest Coast, Plateau, and Plains cultural groups. The authors believe that the similarity of all subgroup profiles demonstrates a significant cultural influence on the results of the MMPI in this population of American Indians.
The purpose of this study was to provide experimental evidence for the role of Gore-Tex polytetraflourethylene as an abdominal wall prosthesis. This was achieved by evaluating tissue reaction in animals to the plastic and comparing it to that of Marlex mesh. Ten Wistar rats received especially prepared Gore-Tex implants, and another ten received Marlex. The materials were inserted in a fashion that yielded results both intraperitoneally and extraperitoneally. Gross and microscopic data were recorded at the time of sacrifice, which ranged from two to ten weeks postoperatively. Grossly, both plastics were found to be similar in intraperitoneal tissue reaction. Microscopically, all of the Gore-Tex grafts retained their original shape and demonstrated focal adherence to the muscle. In contrast, strands of Marlex showed disorganization in the host in 90 per cent of the specimens and no focal adherence to muscle. Instead, it was seen walled off in fibrous tissues. It was concluded that specifically formulated Gore-Tex may provide the more suitable abdominal wall prosthesis and that further research is necessary.

Although the legal basis to refuse life supports is firmly embedded in the laws of all 50 states, there is evidence that a gap exists between patients' preferences and physicians' actions. Patients and their families have increasingly begun to turn to the courts for redress, requesting damages when a physician has ignored their request to forgo life-sustaining treatment. This article explores the reasons why patients' end-of-life medical choices are often ignored by the medical profession and the results of recent attempts to remedy these situations through the courts. Implications for practice are discussed, including practical suggestions for increasing the likelihood that a patient's wishes will be respected by medical providers.
