Prospective multicenter clinical trial of Uretex Sup for surgical treatment of stress urinary incontinence

AIM: To evaluate in a prospective multicenter study the efficacy and safety of the suburethral support Uretex (Sofradim, Trevoux, France) delivered by a suprapubic approach in the treatment of female stress urinary incontinence. METHODS: Between March 2002 and March 2003, 57 patients were treated for stress urinary incontinence with Uretex. Preoperative evaluation included urodynamic examination and questionnaires (symptoms and quality of life, Contilife). Forty patients had pure stress urinary incontinence and 17 mixed urinary incontinence. No associated procedure was performed. The objective cure rate was evaluated by clinical examination and pad-test, and the subjective cure rate was assessed through questionnaires at 1, 3 and 12 months. RESULTS: The mean follow-up was 13 months (range 11-24 months). During follow up, chronic urinary retention requiring a tape section occurred in one patient, and in another patient a delay of vaginal healing was followed by a sling exposure and resection at 4 months. No infection or urethral erosion was reported. The objective cure rate was 96.2%, and the subjective cure rate was 79.2%; four patients reported low leakage on stress and nine patients complained of urge incontinence (four de novo and five persistent). CONCLUSION: The suprapubic Uretex Sup procedure is a safe and effective treatment for women with stress urinary incontinence.     

MRI在心脏瓣膜病中的诊断价值

目的 探讨多序列MR扫描在心脏瓣膜病中的诊断价值。方法 回顾性分析56例心脏瓣膜病患者的影像学资料，患者分别采用超声心动图（UCG）、二维（2D）黑血及亮血序列、K-空间节段真实稳态进动快速扫描序列（True FISP）对瓣膜病进行定性评价，15例患者还进行小角度快速激发（FLASH）电影序列和流速编码电影（VEC）定量分析，并将MR结果与UCG进行对比。结果 UCG和MRI诊断二尖瓣狭窄（MS）2例，二尖瓣关闭不全（MI）23例；主动脉瓣狭窄（AS）7例，其中二瓣畸形5例；主动脉瓣关闭不全（AI）13例；三尖瓣关闭不全（TI）2例；复合或联合瓣膜病9例。受累心腔的增大和升主动脉的扩张是其主要形态学改变，异常的血液湍流信号是受累瓣膜的直接征象。VEC-MR定量分析与多普勒超声一致性好：6例AS，MR和UCG检查结果相关性分析，相关系数和校正相关系数分别为：R=0，975、Rsq=0．951（P〈0．01），AI9例，分别为R=0．965、Rsq=0．932（P〈0．01）。结论 MR多序列综合扫描可对心脏瓣膜病特别是主动脉瓣疾病进行准确的定性及定量评价。

Comorbidity and social phobia: evidence from clinical,epidemiologic, and genetic studies

This paper reviews evidence from clinical, epidemiologic, and family studies regarding the association between social phobia and other syndromes. Social phobia is strongly associated with other anxiety disorders, substance abuse, and affective disorders in both clinical and community samples. An average of 80% of social phobics identified in community samples meet diagnostic criteria for another lifetime condition. Social phobia is most strongly associated with other subtypes of anxiety disorders, with an average of 50% of social phobics in the community reporting a concomitant anxiety disorder including another phobic disorder, generalized anciety, or panic disorder. Approximately 20% of subjects in the community meet lifetime criteria for a major depressive disorder. The onset of social phobia generally precedes that of all other disorders, with the exception of simple phobia. Both clinical severity and treated prevalence are consistently greater among social phobics with comorbid disorders The results of family and twin studies reveal that shared etiologic factors explain a substantial proportion of the comorbidity between social phobia and depression, whereas the association between social phobia and alcoholism derives from a nonfamilial causal relationship between the two conditions. Clinical and phenomenologic implications of these findings are discussed.

脊髓损伤的MR表现

研究脊髓损伤的MR表现。采用GESigna0．5T超导型磁共振检查机，用脊柱表面线圈，对55例脊柱创伤病人做MR检查。所有病例做轮位和矢状位检查，用自旋回波序列和快速自旋回波序列。脊髓损伤表现为脊髓水肿23例次（41．8％），髓内出血10例次（18．1％），脊髓不完全性和完全性断裂7例次（12．7％），椎间盘值22例次（364％），脊柱韧带断裂30例次（545％）。脊髓损伤多见于爆裂型和骨折脱位型脊柱骨折。MR是脊髓损伤最有效的检查方法，MR对发现和评估脊髓损伤优于CT扫描。

Effects of MPP+ on catecholamine levels in adrenal glands and heart of rats

The effects of MPP⁺ (2.5–20 mg/kg) on the adrenal glands and heart were investigated in rats. At various periods after s.c. drug administration the rats were decapitated and tissue catecholamine levels were determined by means of HPLC with electrochemical detection. Adrenal dopamine (DA) levels were reduced at 2–8 h after MPP⁺ administration, but this decrease was followed by an elevation after 16 h and return to the control values after one week. Three successive injections of MPP⁺ caused a statistically significant elevation in adrenal DA, one day, with a tendency to elevation four and seven days after the last injection, whereas a severe (up to 96%) decrease in heart noradrenaline (NA) was found one day after the last injection. Seven days after the last injection a 50% depletion of NA in the heart was still observed. Pretreatment with GBR 12909 (30 mg/kg, 4 h) blocked the MPP⁺ (10 mg/kg, 2 h) induced reduction of adrenal DA levels, but at the same time GBR 12909 failed to block the effects of MPP⁺ in the heart. One day after three successive daily injections of MPP⁺ (10 mg/kg each), the DA-uptake inhibitor GBR 12909 (30 mg/kg, 6 h) could still induce an increase in adrenal DA.MPP⁺ appears to lack persistent cytotoxic action in the adrenal medulla but rather to cause a transient inhibition of DA synthesis followed by a compensatory stimulation. The inhibition can be blocked by specific inhibitor of the DA-uptake mechanism, suggesting a direct effect of MPP⁺ taken up by adrenomedullary cells. The data obtained so far do not suggest any involvement of peripheral dopaminergic nerves in the action of MPP⁺ on the adrenal medulla. The long-lasting depletion of the heart NA, however, suggests a lesion of peripheral noradrenergic nerves.Part of this work was presented at 6th International Symposium on Chromaffin Cell Biology, Marburg, Germany, 18–23 August 1991 Correspondence to: M.
