Tonic pupil,areflexia, and segmental anhidrosis: two additional cases of Ross syndrome and review of the literature

Summary Two patients are described with the triad of tonic pupil, hyporeflexia and segmental anhidrosis (Ross syndrome). Only 18 cases of this syndrome have been reported in the literature so far. While tonic pupil and reduced sweating can be attributed to the affection of postganglionic cholinergic parasympathetic and sympathetic fibres projecting to the iris and sweat glands, respectively, the pathogenesis of diminished or lost tendon jerks remains obscure. To identify the characteristic clinical features, the previous cases of Ross syndrome are reviewed. Recent evidence of subclinical disturbances of sweating in most patients with Adie's syndrome, i.e. tonic pupil and areflexia, casts doubt on the nosological concept of Ross syndrome as a distinct clinical entity.     

Adenocarcinoma of the small intestine: 21-Year review of diagnosis,treatment, and prognosis

Background: The purpose of this study was to evaluate the tumor characteristics and treatment associated with an improved overall survival in patients with adenocarcinoma of the small intestine. Methods: The records of all patients with primary adenocarcinoma of the small bowel seen between January 1971 and December 1991 were reviewed retrospectively. The study comprised 38 patients, 22 (58%) with duodenal tumors, 11 (29%) with jejunal tumors, and five (13%) with ileal tumors. Results: Although not statistically significant, the patients with duodenal adenocarcinoma lived longer than the patients with jejunal or ileal lesions (p=0.77). The overall survival was 23% and seemed to correlate best with absence of lymph node metastases (p=0.04) and pancreaticoduodenectomy for localized duodenal tumors (p=0.04). The patient's age, duration of symptoms, disease-free interval, tumor location, type of recurrence, and histologic grade did not significantly influence survival. Conclusions: The lethality of small-intestinal adenocarcinoma appears to be related to a delay in diagnosis and treatment. When a definitive surgical procedure is performed before lymph node metastases appear, the patient's chance for long-term survival is greatly improved.Presented at the 46th Annual Cancer Symposium of The Society of Surgical Oncology, Los Angeles, California, March 18–21, 1993.

Malignant Peripheral Nerve Sheath Tumor: An Unusual Cause of Intussusception

Malignant peripheral nerve sheath tumors (MPNST) are defined as any tumor arising from a peripheral nerve or showing nerve sheath differentiation. The majority of these tumors arise on the trunk, extremities, or head and neck region. The literature to date has fewer than 14 cases of MPNST arising in the gastrointestinal tract, and only two cases were ever reported in the small intestine, one of which was a recurrent disease. In this paper, we report the first US case of an MPNST arising in the small intestine and presenting as intussusception.

Broad ligament hernia-associated bowel obstruction.

BACKGROUND AND OBJECTIVE: We present the case of a female patient 29 years of age with antecedents of laparoscopic laser ablation for endometriosis, laparoscopic appendectomy, and umbilical hernioplasty. METHODS: The patient was admitted to the hospital's emergency room for abdominal pain in the epigastrium, transfixing, irradiating to both upper quadrants and to the lumbar region, accompanied by nausea and gastrobiliary vomiting. Lipase determination was 170 mg/dL. Other laboratory findings were normal. Plain abdominal films on the patient's admission were normal, and computed tomography (CT) showed data compatible with acute pancreatitis. Without improvement during the patient's hospital stay, pain and vomiting increased in intensity and frequency. RESULTS: New abdominal x-rays revealed dilatation of small bowel loops. Management was begun for intestinal obstruction, with intravenous hydration and placement of a nasogastric tube without a good response. At 48 hours, a diagnostic laparoscopy was performed, revealing a 3-cm internal hernia in the left broad ligament in which a 20-cm segment of terminal ileum was encased. We performed liberation of the ileal segment and closed the hernial orifice by using the laparoscopic approach. CONCLUSION: The patient's evolution was excellent.     

小肠原发性非霍奇金淋巴瘤34例临床分析

目的探讨小肠淋巴瘤的临床特点、治疗和预后。方法对1996年1月至2005年12月间收治的经组织病理学明确诊断、并作免疫学分型的原发性小肠淋巴瘤34例患者的临床资料进行分析。结果27例为B细胞淋巴瘤，7例为T细胞淋巴瘤。腹痛和肠梗阻是主要临床表现。用Ann Arbor分期，22例为Ⅰ～Ⅱ期，其中B细胞淋巴瘤20例（74．1％），T细胞淋巴瘤2例（2／7）；12例为Ⅲ～Ⅳ期，其中B细胞淋巴瘤7例（25．9％），T细胞淋巴瘤5例（5／7）；小肠B细胞淋巴瘤的分期低于T细胞淋巴瘤（P〈0．05）；27例行手术治疗，14例行6次化疗[方案为CHOP（环磷酰胺、阿霉素、长春新碱和强的松龙）]，8例同时加用抗CD20单克隆抗体Rituximab。T细胞淋巴瘤急诊手术率高于B细胞淋巴瘤（P〈0．05），B细胞淋巴瘤更易达到完全缓解（P〈0．05），累计生存率高于T细胞淋巴瘤（P〈0．05）。结论小肠B细胞淋巴瘤Ⅰ和Ⅱ期对手术和化疗效果佳，T细胞淋巴瘤的治疗效果和预后不满意。     

外引流术后的白内障超声乳化手术

目的：探讨抗青光眼餐引流术后的白内障患眼进行超声乳化吸除术的手术入路，操作方式及临床效果。方法：避开功能性滤过泡，选择角巩膜隧道切口或透明角膜切口，瞳孔麻痹性散大时，做一个完美的直径约5mm的连续环形撕囊以补偿之；恰当处理虹膜后粘连后，在病理性小瞳孔下完成超声乳化手术；眼压失控者行青光眼白内障人工晶体植入三联术。结果：无后囊破裂，人工晶体全部囊袋内植入，术后1周视力≥0．5者20只眼（64．5％），0．1－0．4者8只眼（25．8％），＜0．1者3只眼（9．7％）。随访1－16个月，眼压均在20.55mmHg以下。结论：体外流术后的白内障患眼，超声乳化手术因其切口小，并发症少，不破坏功能性滤过泡，不损伤瞳孔，是目前各种手术方法中的最佳选择。     

评价酶联免疫检测血清CYFRA21—1对非小细胞肺癌的诊断价值

目的评价检测ＣＹＦＲＡ２１┐１对非小细胞肺癌的诊断价值。方法用ＥＬＩＳＡ法测定７０例肺癌（ＬＣ）其中４７例非小细胞肺癌（ＮＳＣＬＣ），３例小细胞肺癌（ＳＣＬＣ）和２０例未分型肺癌、６４例肺部良性疾病患者及４０例健康人血清ＣＹＦＲＡ２１┐１浓度。试验的诊断性能用相对操作特征（ＲＯＣ）分析法估测之。结果测得全阈诊断准确率（ＯｖｅｒａｌＤｉａｇ┐ｎｏｓｔｉｃＡｃｃｕｒａｃｉｅｓ）ＬＣ为０．７５、ＮＳＣＬＣ为０．７６，ＳＱＣ为０．８３，ＡＤＥ为０．６７和ＳＣＬＣ为０．３８。在相应于特异性为０．９５的界定值３．４７μｇ／Ｌ处，各型的灵敏度分别为ＳＱＣ０．６２，ＬＣ０．５３，ＮＳＣＬＣ０．５１，ＡＤＥ０．４８和ＳＣＬＣ０．００。结论结果显示ＣＹＦＲＡ２１┐１是ＮＳＣＬＣ较灵敏和特异的一个标志物。未观察到ＴＮＭ各期间该标志物的平均水平有明显的差异；然而异常升高水平的患者的比例随病期的进展而显著增加，提示一系列检测ＣＹＦＲＡ２１┐１水平可能有助于监查ＮＳＣＬＣ患者的疗效。     

Influence of continuous infusion of interleukin-1 alpha on the core protein and the core protein fragments of the small proteoglycan decorin in cartilage.

Decorin, a collagen-binding small proteoglycan, is considered to have a specific function in the organization or stability of the collagen network. Therefore, alteration of its molecular properties may be of pathophysiological relevance during the development of cartilage damage. It is shown here that normal cartilage from rabbit knee-joint contains glycosaminoglycan chain-bearing core protein fragments of 39, 23, and 18 kDa, each one amounting to approximately 5-6% of the intact decorin core protein. Continuous infusion of human recombinant interleukin-1 alpha for 14 days (200 ng/day) into a knee-joint led in condylar cartilage to a reduction in the amount of intact core protein from 2 micrograms/mg wet tissue to about 1.1 micrograms/mg. The increase in its quantity found after infusion of heat-inactivated interleukin-1 was not statistically significant. The concentration of all three core protein fragments became reduced to a similar extent as the intact core protein under the influence of the cytokine, and additional fragments were not found. Surprisingly, there was a much smaller response to interleukin-1-treatment in patellar cartilage.
