Mirizzi综合征的影像学诊断

目的:探讨Mirizzi综合征的发病机理、临床表现、影像学诊断及术前诊断的重要价值.方法:查阅了大量的相关资料文献,进行对比、分析、总结归纳.结果:Mirizzi综合征是胆道系统感染的一种特殊类型,临床少见,极易造成漏诊和误诊,在术中造成不必要的胆道损伤和胆总管探查,影像学检查在诊断此综合征方面有较多的独特优势.结论:Mirizzi综合征术前可以通过影像学检查尤其是超声检查明确诊断.

Clinicopathological study of vesicoureteral reflux (VUR)-associated pyelonephritis in renal transplantation

Abstract:  We retrospectively studied the occurrence of vesicoureteral reflux (VUR)-associated pyelonephritis using renal biopsies obtained from the transplanted kidneys, and correlated the histological changes with clinical parameters. Out of a total of 131 renal biopsies performed between 1990 and 2001 on renal transplant patients at the department of Urology of Nagasaki University Graduate School of Biomedical Sciences, 12 patients showed pyuria more than twice in a single year. Seven of these 12 patients were available for determining VUR by voiding cystourethrography (VCUG). Cystoureterography demonstrated VUR in three of seven studied patients with pyuria. A histopathological examination revealed dilatation of both proximal and distal tubules in renal biopsies of transplant patients with VUR, compared to renal biopsies of transplant patients without VUR, or non-transplanted patients with thin membrane disease. One of the patients with VUR showed advanced features of chronic pyelonephritis in four consecutive biopsies at different time points, suggesting a late stage of reflux nephropathy in the transplanted kidney. We conclude from our study that the occurrence of VUR-related pyelonephritis may be one of the important long-term complications in the survival of renal allografts.     

肠易激综合征Manning诊断标准的评价

目的 评价Manning标准诊断肠易激综合征(IBS)的真实性。方法 采用自行设计的调查表对499例对象进行调查。结果 1．随着Manning标准中结合指标数的增多，IBS组与非溃疡性消化不良及溃疡性结肠炎组鉴别的灵敏度及其95％CI明显下降，特异度及其95％CI明显上升，同时阳性预测值、阳性似然比及阴性似然比也明显上升。2．符合Manning标准中二项以上结合指标，IBS组就具有较好与健康对照组鉴别的灵敏度及其95％CI、特异度及其95％CI。结论 Manning标准中需要3项以上结合指标可较好地使IBS与非溃疡性消化不良或溃疡性结肠炎鉴别；2项以上结合指标可较好地使IBS与健康人鉴别。     

经皮肾穿气压弹道碎石联合体外冲击波碎石治疗上尿路结石

目的 探讨提高上尿路结石碎石成功率的微创治疗方法。方法 采用经皮肾穿微造瘘输尿管镜气压弹道碎石，术中放置双J管，术后配合体外冲击波碎石术(ESWL)治疗上尿路结石48例。结果 结石总排净率为89．1％，结石最小排净率79．2％，无严重并发症发生。结论 该方法结石排净率高，创伤较小，手术并发症少，是上尿路结石较为理想的微创治疗方法。     

Lipoprotein (a) levels in those with high molecular weight apo (a) isoforms may remain low in a significant proportion of patients with end-stage renal disease.

BACKGROUND: Studies have reported an increase in median Lipoprotein (Lp) (a) in patients with high molecular weight (HMW) apolipoprotein (apo) (a) isoforms and renal impairment. Some studies identify Lp (a) levels as a risk factor for vascular disease in renal failure whilst others have demonstrated an association with apo (a) isoform type and vascular disease. METHODS: A total of 239 patients at end-stage renal failure (ESRF) were studied prior to the initiation of dialysis. Blood was taken for Lp (a) levels and apo (a) isoforms. Clinical vascular disease (CVD) was assessed on the basis of clinical history and Rose questionnaire. The control group for Lp (a) levels consisted of 228 healthy volunteers. RESULTS: Despite a higher median Lp (a) level in those with HMW isoforms, 30% of patients had Lp (a) levels <10 mg/dl. Overall, 49% patients were identified as having CVD. Diabetes, smoking history and Lp (a) levels were significantly associated with CVD in logistic regression analysis, although when patients with low molecular weight (LMW) and HMW isoforms were analysed separately, Lp (a) levels were not significantly associated with CVD in those with LMW isoforms. The rates of CVD in those with HMW isoform and low Lp (a) levels were significantly lower than those with HMW isoforms and elevated Lp (a) levels, 34 vs 57% (P < 0.01). CONCLUSIONS: Although median Lp (a) levels in those patients at ESRF with HMW isoforms are higher than controls, in a third of such patients Lp (a) levels remain relatively low. These patients have lower rates of CVD than those with high levels of Lp (a).     

Cutaneous manifestations in the cardiofaciocutaneous syndrome, a variant of the classical Noonan syndrome. Report of a case and review of the literature

We report one patient with cardiofaciocutaneous (CFC) syndrome. He presented with clinical findings characteristic of this condition such as: cutaneous abnormalities, including ichthyosis, widespread keratosis pilaris, a peculiar craniofacial appearance with sparse, curly hair and low-set posteriorly rotated ears; congenital heart defects; and mild mental and motor retardation. We submit a comprehensive review of previously published articles regarding the dermatological findings in CFC syndrome (recently shown to be a variant of Noonan syndrome) emphasizing diagnostic criteria and its differentiation from the Costello syndrome.     

Acute pustulosis of the legs in diverticulitis with sigmoid stenosis: an overlap between bowel-associated dermatosis–arthritis syndrome and pustular pyoderma gangrenosum

BACKGROUND: Bowel-associated dermatosis-arthritis syndrome denotes the occurrence of diarrhoea with arthritis and skin lesions related to bowel disease with or without bowel bypass. In this condition, the histological finding of cutaneous aseptic neutrophilic cell infiltrate is non-specific and common to a wide spectrum of neutrophilic dermatoses, including pyoderma gangrenosum. OBSERVATION: We describe a 78-year-old woman with fever, abdominal discomfort and arthralgias, who developed grouped pustular lesions on her shins with histologically spongiform pustule formation. Aetiological assessment disclosed diverticular disease with sigmoid stenosis. CONCLUSION: Although clinical and histological features in our case fit the diagnosis of bowel-associated dermatosis-arthritis syndrome, they may also correspond to a pustular variant of pyoderma gangrenosum. Our observation raises the question of the nosological classification of bowel-associated dermatosis-arthritis syndrome within the spectrum of neutrophilic diseases.
