Continuous-infusion cisplatin, 5-fluorouracil, and bolus methotrexate in the treatment of advanced non-small cell lung cancer.

BACKGROUND. Cisplatin and 5-fluorouracil have noted synergy in preclinical systems. The authors combined methotrexate with infusional cisplatin and 5-fluorouracil in an attempt to produce a regimen with improved activity in advanced NSCLC. METHODS. Twenty-six ambulatory patients with previously untreated non-small cell lung cancer were treated with continuous-infusion cisplatin (25 mg/m2/day for 5 days), 5-fluorouracil (800 mg/m2/day for 5 days), and intermediate-dose methotrexate (200 mg/m2 on days 15, 22), followed by leucovorin rescue (PFM regimen). RESULTS. Patients received a median of four cycles of therapy. Two patients had a complete response, and 10 had a partial response (overall response rate, 46.2% or 12 of 26). The median time to treatment failure was 22.5 weeks; the median survival was 55 weeks from the start of chemotherapy. There were no toxic deaths attributed to chemotherapy. Thrombocytopenia was the only Grade 4 toxicity (27%). Grade 1/4 and 2/4 peripheral neuropathy occurred in 17 of 26 patients (66%) and was associated with a cumulative cisplatin dose of more than 300 mg/m2. CONCLUSIONS. PFM (using continuous-infusion cisplatin) produced a high response rate but resulted in an high incidence of low-grade peripheral neuropathy.     

Liver transplantation for erythropoietic protoporphyria liver disease.

In erythropoietic protoporphyria (EPP), there is excessive production of protoporphyrin, primarily in the bone marrow, resulting in increased biliary excretion of this heme precursor. Some patients will develop progressive liver disease that may ultimately require liver transplantation. However, excessive production of protoporphyrin by the bone marrow continues after transplantation, which may cause recurrent disease in the allograft. This study was performed to define post-transplant survival, the risk of recurrent disease, and specific management issues in patients transplanted for EPP liver disease. The patients studied consisted of twelve males and eight females, with an average age of 31 (range, 13-56) years at the time of transplantation. The estimated maximum MELD score prior to transplant was 21 (range, 15-29). Unique complications in the perioperative period were light induced tissue damage in four patients and neuropathy in six, requiring prolonged mechanical ventilation in four. Patient and graft survival rates were 85% at 1 year, 69% at 5 years, and 47% at 10 years. Recurrent EPP liver disease occurred in 11 of 17 patients (65%) who survived more than 2 months. Three patients were retransplanted at 1.8, 12.6, and 14.5 years after the initial transplant for recurrent EPP liver disease. In conclusion, the 5-year patient survival rate in patients transplanted for EPP liver disease is good, but the recurrence of EPP liver disease appears to diminish long term graft and patient survival.     

Role of Alcohol-induced Hypothermia in Mediating the Teratogenic Effects of Alcohol in C57BL/6 J Mice

The purpose of this study was to determine the role of alcohol-induced maternal hypothermia in the teratogenic actions of alcohol. C57BL/6J mice were administered an acute dose of alcohol (5.8 g/kg orally) or isocaloric sucrose on day 10 of gestation. One half of each group was placed for 6 hr in an incubator set at 32 degrees C and the other half was housed in the incubator at room temperature (22 degrees C). As expected, acute prenatal alcohol exposure at this time of gestation was associated with decreased birth weight and an increase in limb and kidney malformations. The significant alcohol x environmental temperature interaction on these dependent variables indicated that the teratogenic insult was not attenuated, but was in fact even greater for the 32 degrees C/alcohol group. An absence of a main effect of environmental temperature indicated that the 32 degrees C environment, per se, was not teratogenic. Thus, maternal hypothermia is probably not an etiological factor in animal models of fetal alcohol syndrome. Moreover, antagonism of alcohol-induced maternal hypothermia exacerbates the teratogenic actions of alcohol observed at room temperature.     

Psychiatric rehabilitation in a French-speaking setting: current practices, future challenges]

This paper aims to assess current interventions in psychiatric rehabilitation in the French-speaking world and to discuss future developments. We review examples of policies and practices in Quebec and Europe and discuss the role and involvement of professionals; namely, the psychiatrists and the nursing staff. We also present different rehabilitation strategies and techniques used in the French-speaking world, such as case management, social-skills training, cognitive therapies for psychotic symptoms, family interventions, and return-to-work interventions. In conclusion, we invite psychiatrists to play a more active role in rehabilitation. We recommend the creation of small, specialized units closely linked to the needs of clients, and we propose to integrate social and medical interventions, rather than opposing them.     

Personal and family risk factors for adolescent suicidal ideation and attempts.

Despite research indicating that suicidal ideation is strongly related to future suicide attempts, there is limited data on variables associated with continued suicidal ideation and behaviors in adolescents. The objective of this study is to investigate whether personal, cognitive and family risk factors can differentiate adolescent suicidal ideation and attempts. Twenty-four attempters, 50 ideators and 50 non-suicidal adolescents (aged 14 to 25 years) were asked during an interview to complete individual and psychosocial measures. Both suicidal groups reported greater personal vulnerability and perceived their family as less functional than did the non-suicidal group. However, no differences were found between both suicidal groups. The results suggest the presence of common factors in both adolescent suicidal ideators and attempters.     

Methodological issues in music interventions in oncology settings: A systematic literature review

This paper is part of a systematic literature review and presents methodological issues within studies, investigating therapeutic applications of music in cancer patients. This review focuses on published international research from the USA, Canada, Australia and European countries using four electronic databases: PSYCHINFO, WEB OF SCIENCE, MEDLINE and SCIENCEDIRECT. Thirty-two papers were identified and each paper was coded in terms of sample type, basic research question, research design and methodological details, results and implications for future research. This paper addresses questions related to study design and methodology. It explores and discusses the relative advantages and disadvantages of various approaches.     

Pituitary volume in pediatric obsessive-compulsive disorder.

BACKGROUND: Abnormalities in the limbic-hypothalamic-pituitary-adrenal (LHPA) axis have been implicated in the pathogenesis of obsessive-compulsive disorder (OCD). To our knowledge, however, no prior study has measured pituitary gland volume in OCD. METHODS: Volumetric magnetic resonance imaging studies were conducted in 31 psychotropic drug-na?ve children (10 boys, 21 girls) aged 8-17 years and 31 case-matched healthy comparison subjects. RESULTS: Pituitary volume was significantly smaller in patients with OCD as compared with healthy control subjects (11% smaller). Smaller pituitary volume in patients with OCD was associated with increased compulsive but not obsessive symptom severity. Boys with OCD had smaller pituitary gland volumes compared with control boys (20% smaller). No significant differences in pituitary volume were observed between girls with OCD and control girls. Boys with OCD had significantly smaller pituitary volumes than girls with OCD (31% smaller), whereas control boys also had smaller pituitary gland volumes compared with control girls (21% smaller). CONCLUSIONS: These findings provide new evidence of reduced pituitary volume in pediatric OCD that seems to be more prominent in male patients. The observed alterations in pituitary volume are consistent with neuroendocrine studies that have reported abnormalities in the LHPA axis in OCD.
