基于肿瘤影像学异质性分析CT在诊断十二指肠恶性肿瘤的价值

目的 探讨十二指肠肿瘤血流量存在的异质性及容积灌注CT成像对降低肿瘤异质性的影响。方法 纳入我院2013年1月至2014年11月十二指肠结节病例的132例,其中腺癌48例,间质瘤52例,淋巴瘤32例。所有的病例均行单层面灌注CT和容积灌注CT成像扫描,比较两者对十二指肠恶性肿瘤的诊断效能,采用变异系数评价两者在影像学异质性的差异,评价肿瘤影像学异质性对十二指肠恶性肿瘤的影响。结果 容积灌注CT成像与单层面灌注CT诊断恶性结节的效能其敏感性、特异性、准确性、阴性预测值、阳性预测值比较均无明显差别(P0.05);中高分化组及低分化组两个亚组的容积灌注CT成像的变异系数也均小于单层面灌注CT的变异系数,组间相比具有统计学差异(P0.05);血流量差异性的大小相比具有统计学差异(P0.05)。结论 容积灌注CT成像与单层面灌注CT检查在诊断效能上无明显差异,稳定性好,肿瘤影像学异质性对评价十二指肠肿瘤血流量有着一定影响,容积灌注CT成像能够降低肿瘤异质性的影响。     

腔内激光治疗大隐静脉曲张192例报告

目的 探讨腔内激光治疗大隐静脉曲张的疗效。方法 2004年7月～2006年3月我院对192例238条肢体大隐静脉曲张行高位结扎、激光烧灼静脉主干和小腿曲张静脉。小腿局部严重曲张的静脉团,另做切口做局部切除或点状抽拨。结果 本组一次治愈率96.2%（229/238）。9例9条肢体术后因仍有少量曲张静脉存在,局麻下行切除或再次激光治愈。114例大隐静脉主干及小腿局部条索状硬结、疼痛;9例皮肤灼伤。术后住院时间4～8 d,平均5.6 d。158例随访1～18个月,平均11.6月,未见复发。结论 腔内激光治疗大隐静脉曲张效果确切,创伤小。     

Admission rates for peptic ulcer in the Trent Region, UK, 1972–2000: Changing pattern, a changing disease?

BACKGROUND AND AIM: Peptic ulcer disease is believed to be less common and less severe as a result of modern medical treatment. We therefore examined changes in the admission rates for patients with duodenal ulcer and gastric ulcer, both emergency (for haemorrhage, perforation or severe pain) and for elective surgery, before and since the introduction of the new advances in therapy. These admission indices reflect disease prevalence and severity. PATIENTS AND METHODS: We identified admission rates during 1972--2000 within the Trent Regional Health Authority, UK (population 4.7 million), from computerised patient information using diagnostic search codes ICD8-10 and expressed as rates per million resident population. Drug expenditure details were obtained from the Department of Health. RESULTS: Emergency admission rates as a whole changed little, a decline in the young being offset by an increase in the elderly. Haemorrhage was the most common reason (approximately 115 per million for duodenal ulcer and 87 for gastric ulcer) throughout [compared with perforation (80 and 21) and pain (90 and 68)]. In contrast, elective surgery has almost disappeared; this reduction began before the introduction of modern treatment. CONCLUSION: Emergency admission rates for duodenal and gastric ulcer for complications or severe pain have fluctuated over the last three decades but with little overall change. In contrast, elective surgery has declined dramatically, as a result of advances in treatment but also from changes in the natural history.     

奥美拉唑联合呋喃唑酮及阿莫西林治疗十二指肠溃疡疗效观察

目的 观察奥美拉唑联合呋喃唑酮及阿莫西林治疗十二指肠溃疡的疗效.方法 将十二指肠溃疡患者50例随机分为两组:治疗组26例,予以奥美拉唑每日清晨空腹口服20 mg,治疗4周,呋喃唑酮100 mg,3次/d,阿莫西林1000 mg,2次/d,治疗2周,治疗期间不加其他药物.对照组:奥美拉唑每日清晨空腹口服20 mg,治疗4周.结果 治疗组:治愈率53.85%,好转率42.31%,有效率98.16%;对照组:治愈率41.67%,好转率37.50%,有效率79.17%.治疗组和对照组总有效率经统计学处理有显著差异(P＜0.05).结论 奥美拉唑联合呋喃唑酮及阿莫西林治疗十二指肠溃疡能改善临床症状和促进溃疡愈合.     

内镜下交通支结扎治疗下肢复发性静脉性溃疡

摘要：目的: 探讨内镜深筋膜下结扎交通支治疗下肢复发性静脉性溃疡的疗效。方法:手术治疗50例(56条)下肢复发性静脉性溃疡患者，行内镜下交通支静脉离断术，对术后溃疡愈合情况进行1~3年随访。 结果:55条下肢溃疡在10~49d内愈合，1条90d未愈，行小隐静脉高位结扎术后溃疡愈合。随访1~3年，6个月后复发1例，抗炎换药后愈合。18个月后2条复发，再行小隐静脉高位结扎术后溃疡愈合。 结论:腔镜深筋膜下交通支静脉结扎术安全有效，损伤小，并发症少，是治疗下肢复发性静脉性溃疡较为有效的方法。

Ulcer of the tongue as a presenting feature of pulmonary tuberculosis

Oral tuberculosis is very rare and when present they are usually secondary to pulmonary tuberculosis. Tuberculous lesions of the tongue have become so infrequent that they are virtually a forgotten disease entity and may pose a diagnostic problem. The case reported in this paper emphasizes the importance of including tuberculosis in the differential diagnosis of any chronic oral ulcer. The low number of oral infections by M. tuberculosis could be due to underreporting.

An Examination of the Alcohol Consumption and Peptic Ulcer Association—Results of a National Survey

Excessive alcohol consumption causes damages to the stomach or duodenum by impairing the integrity of the mucosal barrier. The aim of this study was to estimate the association between alcohol consumption and peptic ulcer, utilizing a large representative sample of the U.S. population, while controlling for cigarette smoking and major sociodemographic variables. Results indicated that alcohol consumption only minimally increased the odds of peptic ulcer. Thus, this study offers little support for the association between ethanol intake and peptic ulcer.
