目的 探讨空回肠间质瘤的诊断和治疗经验。方法 对我院 1993年 10月~ 2 0 0 4年 1月收治的有完整资料的 13例空回肠间质瘤病例进行回顾性分析 ,本组患者均经术后病理和免疫组化证实。结果 本组患者主要临床表现为消化道出血、腹痛。发病至确诊时间 2个月至 7年。剖腹探查确诊 7例 ,腹腔镜腹腔探查确诊 4例 ,术前确诊的仅 2例。随访 2个月至 9年 ,除 1例死于其它疾患外 ,余 12例均健在 ,无空回肠间质瘤复发病例发现。结论 小肠间质瘤预后甚好 ,但本病缺乏特征性的临床表现及有效的诊断手段 ,易致长期延误诊治 ;对长期不明原因的消化道出血患者 ,及早行剖腹探查或腹腔镜腹腔探查是避免小肠间质瘤长期延误诊治 ,改善患者预后的关键 相似文献

ABSTRACT Recent research has demonstrated the importance of family relationships in women's experience of premenstrual changes, their construction of these changes as “PMS.” However, the discursive process by which women take up the subject position of “PMS” sufferer through the explicit naming of “PMS” to an intimate partner has received little research attention. Drawing on 60 individual interviews with Australian women, conducted between 2004 and 2006, we examined accounts of naming “PMS” in intimate relationships, women's explanations for naming or not naming, their experiences of their partner naming them as premenstrual. The analysis process identified an overarching theme of naming “PMS,” which was made up of three themes: naming to explain; “PMS” becoming the only explanation for distress; “PMS” as not a legitimate explanation for distress. The findings suggest that clinicians need to be aware of women's complex, often ambivalent, experiences of naming “PMS” within their relationships, when working with women, couples, seeking treatment or support for premenstrual distress. 相似文献

We describe an intensive group program for older adults, facilitated by a tobacco cessation specialist and a geriatric social worker, designed to focus on factors that maintain smoking behavior. Integral components dealt with issues specific to the older adult such as social isolation or economic need. Pharmacological therapy was provided. Participants with a mean age of 67 years who smoked an average of 19 cigarettes per day completed the program. Sixty-six percent of participants had been treated or were in treatment for depression and/or anxiety. Follow-up was completed at 1, 3, 6, and 12 months. The cessation rate across follow-up points was 68%. This program shows that older adults can maintain smoking cessation when provided with programs designed to address their issues. 相似文献

An epidemiologic study by questionnaire was undertaken in Great Britain and the United States, to provide data on diabetes mellitus in Down’s syndrome. Among 20,362 patients with Down’s syndrome, 88 living diabetics were found. A high prevalence of diabetes in the population with Down’s syndrome, particularly In the younger age groups, was noted. In these age groups the prevalence of diabetes in the population with Down’s syndrome exceeded that of the general population by factors 6.8, 3.3, and 3.0. Insufficient data exist to determine the exact statistical significance of these ratios. Further investigation is necessary. Nevertheless, a definitive association between Down’s Syndrome and diabetes mellitus is suggested. The role of prediabetes, autoimmunity and genetics in this association is discussed. 相似文献
