Arthrograms of the temporomandibular joint were obtained in 20 symptomatic joints that had previous reconstructive arthroplasty with disk repositioning because of internal derangements. Preoperative arthrograms were available for comparison in 18 joints. Symptoms resulting in a postoperative arthrogram included pain, limited ability to open the mouth, and clicking of the joints. Postoperative arthrographic findings included limited anterior translation of the condyle (90%), irregularity in outline of the intraarticular contrast agent (60%), a conical configuration of the posterior recess (25%), decreased size of the joint (28%), anterior displacement of the meniscus (25%), and perforated meniscus (15%). Many of these findings may have resulted from fibrosis and scarring, which may be a response to intraarticular bleeding. The mechanism by which the fibrosis causes the postsurgical arthrographic features is discussed. 相似文献
BACKGROUND: Quality of life (QOL) assessment has emerged to measure and
quantify the balance between treatment benefit and toxicity, and has a
value in predicting response and overall survival in cancer patients.
METHODS: From July 1995 to February 1997, 38 symptomatic patients with
advanced non-small cell lung cancer (NSCLC) were treated with MIP
chemotherapy (mitomycin 6 mg/m2, ifosfamide 3000 mg/m2 and cisplatin 50
mg/m2 on day 1 every 3 weeks). Patients were assessed for QOL including
physical well-being, general symptoms and lung cancer-specific symptoms, as
well as objective response. RESULTS: The overall response rate was 38.9%
(14/36, all were partial response) and the median duration of response was
3.5 months [95% confidence interval (CI) 2.0-4.0]. The median duration of
overall survival was 7 months (95% CI 5.9-8.5). The overall improvement of
QOL was 58.3% with 21 patients feeling better on treatment. The toxicity of
chemotherapy was mild, mainly nausea/vomiting and minimal alopecia. Using
multiple clinical predictors of survival (age, histology, stage,
performance status), only change of QOL emerged significantly (P = 0.0007).
CONCLUSIONS: MIP had an endurable response and low toxicity profile, and
provided good QOL. Integral QOL data in our study provided the strong
prediction of survival in advanced NSCLC. Further experienced QOL study
will provide greatly enhanced outcome data in clinical trials.

We present a study on selection of a psychometric scale to be clinically used among Indigenous people with depression. Our aim was to select a psychometric tool for cultural adaptation with Mohawk and Inuit in Quebec.
Methods
We selected three depression scales and three protective factor scales based on: strong validity for psychometric properties, evidence for good psychometric qualities across translations, avoidance of cognitively complex sentences, brevity, and clarity. We submitted the scales for consultation, and followed qualitative participatory methods with Mohawks of Kahnawake and Inuit from Nunavik living in an urban environment. We collected data through ten focus groups with advisory committees, and carried out a thematic analysis of the information.
Results
The advisory groups considered the measurement scales to be unsafe. The major components that hindered their acceptance were: numeric rating, self-evaluation (versus supportive interaction), and a focus on symptoms rather than supportive factors. The participants preferred the Growth and Empowerment Measure due to its empowering approach. They voiced that it is necessary to develop a culturally sensitive and safe tool which facilitates interactions between the person and the practitioner.
Conclusion
This project provides valuable information about the perspectives of local Indigenous peoples regarding mental health and factors of empowerment and resilience. The ideal tool should be flexible in terms of the content and its use as compared to the conventional psychometric strategies. A tool developed with the Indigenous perspective on wellbeing could be used in psychological and psychiatric intervention as well as in social and community services.
The combination of high-dose busulfan (16 mg/kg) and 200 mg/kg cyclophosphamide is gaining increasing significance as a preparative regimen prior to autologous, syngeneic, or allogeneic marrow transplantation. A new regimen of high-dose busulfan in conjunction with a reduced dose of 120 mg/kg cyclophosphamide has recently been described as a preparative regimen prior to allogeneic transplantation. To determine the drug-related nonhematologic toxic effects of this new regimen without confounding factors associated with allogeneic transplantation, we conducted a pilot study using this new regimen in 20 patients with acute myeloid leukemia (AML) in first remission prior to autologous unpurged marrow transplantation. All patients experienced transient non-life-threatening acute drug-related toxicity with skin reactions in 20 (100%), nausea and vomiting in 20 (100%), oral mucositis in 18 (90%), hepatic functional impairment in 17 (85%), hemorrhagic cystitis in three (15%), and generalized seizures in two (10%) of these patients, respectively. Two procedural, fatal complications resulted from infectious causes that were not directly related to the speed of hematopoietic reconstitution or the toxicity of the preparative regimen. The 3-year event-free survival estimate (55% +/- 11%) and probability of leukemic recurrence (38% +/- 11%) attained with this new regimen in recipients of autografts in first remission of AML are promising and challenge comparisons with preparative regimens employing combinations of cytotoxic agents or total body irradiation (TBI). 相似文献
Elimination of neoplastic B cell populations from autologous bone marrow grafts also removes normal B lymphocytes. This is potentially hazardous for the reconstitution of the immune system in patients undergoing high-dose chemotherapy and total body irradiation followed by autologous marrow rescue. Five pediatric patients with B cell non- Hodgkin's lymphoma in first remission undergoing such a regimen were studied. They received bone marrow pretreated with anti-Y 29/55 monoclonal antibody and complement. B and T lymphocyte subpopulations reached normal levels within 6 months after autologous bone marrow transplantation (ABMT), and serum immunoglobulin levels became normal within 4 to 9 months. Vaccination with diphtheria and tetanus toxoid, trivalent poliomyelitis vaccine of the Salk type, and pneumococcal capsular antigens (38 to 54 months after transplantation) gave rise to specific antibody production. ABO isoagglutinins could be demonstrated in all patients. The response pattern was similar to that of patients who received unmanipulated autologous bone marrow. It is concluded that ex vivo anti-Y 29/55 depletion of the marrow graft does not induce relevant disturbances of humoral immune functions. 相似文献
