Discussing options between patients and health care professionals in genetic diagnosis: ethical and legal criteria

The specific characteristics of genetic data lead to ethical-legal conflicts in the framework of genetic diagnosis. Several international organisations, including UNESCO and the Council of Europe, have enacted rules referring to the use of genetic information. This paper discusses possible legal and ethical criteria that could be used in genetic testing.     

Synovectomy of the knee in hemophilia

Synovectomy of the knee in patients with hemophilia presenting in countries with demographic characteristics that make central referral difficult is the subject of this article. Ten patients, six surgeons, and two countries contributed to this study, which demonstrated that approximately 40% of these patients had no further hemarthroses into the affected joint and the remainder had reduced frequency and severity of bleeding. Continuous passive motion has an important place in postoperative management, and manipulation with the patient under anesthesia is of doubtful value. The possible relationship between diminished range of movement and a successful outcome in terms of abolition of hemorrhage is explored. One patient underwent synovectomy of the knee without complication; the other nine suffered significant complications.     

A stepped care approach to reduction of anterior shoulder dislocation in the prone position.

There are various methods of reducing anterior shoulder dislocations. The traditionally used methods like Kocher's and Hippocratic are associated with procedural complications and frequently require sedation/muscle relaxants which have their own complications and are associated with longer stay and monitoring requirement in the emergency department. We describe a stepped care approach to shoulder dislocation reduction in the prone position involving four steps and two new manipulation methods taking into consideration the pathological deforming forces in a dislocated shoulder and addressing them in a stepwise fashion. This method does not require sedation/muscle relaxants in the majority of cases, is easy to learn, relatively painless, associated with shorter stay in the emergency department and has fewer complications.     

Elevation of cell adhesion molecule immunoreactivity in the anterior cingulate cortex in bipolar disorder.

BACKGROUND: Neuroimaging reports of increases in signal hyperintensities in white and deep gray matter and other work indicate that there might be an inflammatory response in affective disorders. METHODS: The microvascular immunoreactivity of intercellular adhesion molecule-1 and vascular cell adhesion molecule-1 was measured with image analysis in postmortem tissue from the anterior cingulate cortex (ACC) and dorsolateral prefrontal cortex (DLPFC) from 15 unipolar and 15 bipolar subjects and compared with each other and with 15 subjects with schizophrenia and 15 control subjects. RESULTS: Intercellular adhesion molecule-1 immunoreactivity in gray and white matter of the ACC in bipolar subjects was increased compared with control subjects (gray: p =.001; white: p <.001) and schizophrenic subjects (gray: p =.016; white: p =.025) and modestly increased in white matter compared with unipolar subjects (p =.049). No such differences were found in the DLPFC. CONCLUSIONS: These findings are consistent with the presence of an inflammatory response in the ACC in bipolar disorder.     

Penetrating abdominal vena cava injuries.

OBJECTIVE: The surgical management and outcome of abdominal vena cava (AVC) injuries is presented. STUDY DESIGN, PATIENTS AND METHODS: A retrospective record review of patients with AVC injuries treated in the Trauma Unit at Groote Schuur Hospital between January 1999 and December 2003 was undertaken. Demographic data, mechanism of injury, surgical management, associated injuries, duration of hospital stay, complications and mortality were extracted from patient records. Patients with acute peritonitis and/or shock underwent emergency laparotomy. RESULTS: Forty-eight patients with AVC injuries were identified. Gunshot wounds accounted for 45 (94%) injuries. The mean weighted revised trauma score, injury severity score (ISS) and penetrating abdominal trauma index (PATI) were 6.3, 24 and 42, respectively. The AVC injury was infrarenal and suprarenal in 41 and seven patients, respectively. Thirty injuries were ligated. There were 15 deaths (31%). Significant differences between survivors and non-survivors included ISS, preoperative hypotension and blood transfusion requirements, whereas site of injury, PATI, and surgical management did not. CONCLUSION: Abdominal vena cava injuries are associated with a high mortality. Ligation of the AVC in critically ill patients is a feasible and life-saving option.     

Eight Days of Cyclosporine Overdose: A Case Report

A 25–year-old woman was admitted to the hospital because of rising trough cyclosporine concentrations thought to be due to self-administration of 4 times the normal dosage of the drug for 8 days. Her symptoms included colicky central abdominal pains and urinary retention; her serum creatinine concentrations were elevated. Whole blood cyclosporine and metabolite concentrations were measured by high-performance liquid chromatography and monoclonal radioimmunoassays. The highest reported trough cyclosporine concentration was 5877 ng/ml, and AM1 (M17) concentration was 3425 ng/ml. A cyclosporine half-life of 91 hours was calculated. Nine days after the agent was discontinued the patient's serum creatinine concentration had returned to normal and her symptoms resolved. Due to the availability of three sizes of cyclosporine capsules, and the need for frequent dosage changes, continued vigilance is necessary to ensure that patients understand their drug regimen.
