Objective. To assess the health-related quality of life (HRQl) of 8-to 12-year-old children undergoing therapy for cancer or childhood-cancer survivors by using the Minneapolis-Manchester Quality of life-Youth Form(MMQl-YF),a comprehensive,multidimensional self-report instrument with demonstrable reliability and validity. Design,Setting,and Patients. The MMQl-YF consists of 32 items comprising 4 scales:physical functioning,psychologic functioning,physical symptoms,and outlook on life. Scoring on the MMQl ranges from 1 to 5; 5 indicates maximal HRQl. An overall quality-of life (QOl) score is also computed. By using a cross-sectional study design,the MMQl-YF was administered to 90 off-therapy cancer survivors,72 children with cancer undergoing active therapy,and 481 healthy children without a history of cancer or other chronic disease. Results. Compared with healthy controls,children actively undergoing cancer treatment report low overall QOl,physical functioning,and outlook-on-life scores. However,off-therapy survivors report a superior overall QOl,compared with age-matched healthy controls. Conclusions. Young survivors of childhood cancer report a favorable HRQl relative to healthy controls. These results are reassuring,suggesting that this group of survivors may have been too young to encounter some of the negative psychosocial impacts of cancer and its treatment.

Aim: To define the clinical and histopathological characteristics of primary lacrimal sac lymphoma in a predominantly white population. Methods: Specimens of lacrimal sac lymphoma and follow up data were solicited from members of the Ophthalmic Oncology Task Force of the european Organization for Research and Treatment of Cancer (eORTC) and the european Ophthalmic Pathology Society (eOPS). Specimens were stained with haematoxylin and eosin and an immunohistochemical panel against leucocyte antigens was applied. Diagnosis was reached by consensus of five experienced pathologists according to the World Health Organization classification system. The histopathological findings were correlated with the clinical data. Results: Of 15 primary lacrimal sac lymphomas, five (33%) were diffuse large B cell lymphoma (DlBCl), five (33%) were extranodal marginal zone B cell lymphoma of mucosa associated lymphoid tissue (MAlT lymphoma), three were classified as “transitional MAlT lymphoma,”being in transition from MAlT lymphoma to DlBCl, and two were unclassified B cell lymphomas. Nine of the patients were female, and the median age at the time of diagnosis was 71 years (range 45-95 years). The most frequent presenting symptoms were epiphora (85%), swelling in the region of the lacrimal sac (79%), and dacryocystitis (21%). All but one patient presented in stage I. Systemic spread occurred in three of nine patients (33%). The 5 year overall survival was 65%. Conclusions: DlBCl and MAlT lymphoma are equally common in the lacrimal sac in contrast with the remaining periorbital and/or orbital region where MAlT lymphoma predominates.

关于区分生油岩和作为生油岩标志的相对数值的方法Philippi已提出过报告。区分的根据是本地原油和运移原油的分异作用。沉积物中有机质的总含量和可抽提烃类的含量,标志着这种分异作用。用以划分生油岩的相对数值是根据可抽提烃类的含量而定的。沉积物中总有机质的测定是一个困难问题,不能根据常规的方法来处理,合理的总有机质含量并不是总有机碳含量。测定碳的方法是根据碳氧化成二氧化碳,然后测定所生成的二氧化碳。文献中所报导的方法主要是关于有机化合物中的总碳和钢铁中碳的方法,大多是在氧气中燃烧氧化成二氧化碳的方法。二氧化碳一般用所产生气体的体积或重量测量。土壤中总碳的测量一般是用重铬酸氧化碳,然后称重所产生的二氧化碳。

低浓度甲基二磷戊二醛可引起接触致敏

世界核心医学期刊文摘（皮肤病学分册） 2005年第3期1卷 53-54页

作者： Pedersen l.K. Agner T. Held e. Johansen J.D. 崔荣 Natl. Allerg. Re s. Ctr. Consum. P. Gentofte Hospital University of Copenhagen Copenhagen Denmark

Background: The rapidly increasing level of contact allergy to methyldibromog lutaronitrile (MDBGN) in europe is of concern. In April 2003, the eU Commission prohibited the use of MDBGN in leave-on cosmetic products, such as creams and lotions, until a level of safe use can be defined. Industry risk assessment has indicated that such a safe level could be 50- 100 p.p.m. Objectives: To determi ne whether 50 p.p.m. or 100 p.p.m. could be tolerated by MDBGN-sensitized indi viduals, and to evaluate if the risk for elicitation of MDBGN allergy is higher for a leave-on product with a high lipid content than for a product with a low lipid content. Methods: eighteen volunteerswith contact allergy to MDBGN and 10 healthy controls were exposed to repeated open application tests (ROATs) with t wo moisturizers with a high and a low lipid content, respectively, both containi ng MDBGN at a concentration of 50 p.p.m. The ROATs were performed on the left an d the right side of the neck for 14 days, or until a positive re action was seen. If a positive reaction did not develop within the first 14 d ays, two analogous moisturizers containing 100 p.p.m. MDBGN were applied for a f urther 14 days. Clinical assessments were done on days 2, 3, 7, 14, 21 and 28 or when a reaction developed. Results: eleven of 18 (61% ) subjects developed der matitis on the test area, of whom 10 developed a positive reaction to the 50 p.p .m. moisturizer, seven having a positive reaction on day 2 or 3. Reactions to th e low-lipid moisturizer were the more frequent. All participants used more of the low-lipid moisturizer than the high-lipid moisturizer. The controls all had negative ROATs. Conclusions: even 50 p.p.m. cannot be regarded as a safe con centration for use and the prohibition of MDBGN is scientifically well founded.

PURPOSe: Current colonoscopy guidelines do not address the issue of when to stop performing screening and surveillance colonoscopy in the elderly. We reviewed our experience and results of colonoscopy in patients aged 80 years and older to assess the risks and diagnostic yield in this population. MeTHODS: We reviewed retrospectively the endoscopic and pathologic reports from consecutive colonoscopies performed on patients aged 80 years and older at a single, high-volume endoscopy center between August 1999 and May 2003. Patient characteristics, indications for examination, findings at colonoscopy, and complications were recorded and analyzed. ReSUlTS: A total of 1,199 colonoscopic examinations were performed on 1,112 patients. Average age was 83.1 (range, 80-100) years. Male∶female distribution was 1∶1.7. leading exclusive indications for colonoscopy included: polyp surveillance, 227 (19 percent); altered bowel habits, 168 (14 percent); iron-deficiency anemia, 132 (11 percent); and cancer follow-up, 108 (9 percent). eighty-six examinations (7 percent) were performed solely for an indication of colorectal cancer screening. Twenty-two percent of patients had more than one indication for colonoscopy. Forty-five malignancies were found (3.7 percent). No cancers were found in the screening group, and two malignancies (0.7 percent) were detected in patients undergoing colonoscopy for polyp surveillance. There were eight (0.6 percent) reported major complications. CONClUSIONS: Colonoscopy can be performed safely in patients aged 80 years and older. However, the diagnostic yield is low, particularly in patients undergoing routine screening or surveillance exam-inations. Colonoscopy should for the most part be limited to elderly patients with symptoms or specific clinical findings.

Abstract Abstract Background: Our series of patients with idiopathic pancreatitis (IP) found a cystic fibrosis (CF) gene abnormality in 19% compared with 3.5% in patients without pancreatitis. Objective: The objective was to determine whether the CF gene predicts more severe eRP findings. Design: This was a retrospective case-control study. Setting and Patients: From July 1998 to August 2004, CF gene analysis was performed in 819 patients with IP via Genzyme Genetics. The panel tests for 70 to 87 alleles and has a detection rate of more than 90% of the cases. Sixty-nine patients (8.4% ) who had at least one CF gene positive mutation were the study cohort. A total of 218 patients with IP and negative CF gene mutation were randomly selected from our database to be in the control group. Main Outcome Measurements: Pancreatograms were evaluated for chronic pancreatitis (CP) based on Cambridge criteria. The results of the gene analysis were not available at the time of pancreatogram interpretation. Results: Among patients positive for the CF gene, 42 (61% ) were women. The mean age at intervention was 40 years (range 14-80 years), and 48 patients (70% ) had cholecystectomy. Among patients who were negative for the CF gene, 147 (67% ) were women. The mean age at intervention was 41 years (range 9-89 years), and 125 patients (57% ) had cholecystectomy. Compared with controls, cases had higher incidence of CP (62% vs. 48% , p = 0.05), grade III CP (35% vs. 18% , p = 0.004), pseudocysts (12% vs. 4% , p = 0.036) and pancreatic strictures (20% vs. 8% , p = 0.008). limitations: The limitations of the study were (1) retrospective design and (2) the panel used tests only for 70 to 87 alleles (of approximately, 900 CF transmembrane conductance regulator genes known). Conclusions: The mean age at intervention in both groups was similar. CP, grade III CP, pseudocysts, and pancreatic strictures were more common among patients who were CF gene positive.
