Porocarcinoma coexisting at a site of Bowen disease in a 63‐year‐old woman

Porocarcinoma is an unusual, locally aggressive and potentially fatal neoplasm. Several cutaneous malignancies have been described in association with porocarcinoma, including squamous cell carcinoma, basal cell carcinoma and tricholemmal carcinoma. Previous reports have indicated that the occurrence of malignant tumours in combination with porocarcinoma is extremely rare, in particular with regard to Bowen disease (BD). We report an uncommon case of porocarcinoma occurring synchronously in a single BD lesion in a 63‐year‐old woman with multiple BD lesions. The clinical and histological findings confirmed this diagnosis.

The quality of spontaneous adverse drug reaction reports from the pharmacovigilance centre in western China

Background: High-quality adverse drug reaction (ADR) reports are essential for conducting drug safety monitoring in pharmacovigilance. The study aim was to assess the current quality of ADR reports in western China, and to identify problems with ADR report quality.

Research design and methods: A sample of 1139 reports received by the Shaanxi ADR Monitoring Center from January 2015 to December 2017 was selected. ADR report quality was evaluated using an ADR report quality evaluation system.

Results: None of the reports were rated as excellent and 1.40% (n = 16) as good. Report quality was better for new and serious reports than for general reports. Medical institutions generated higher quality reports than pharmaceutical manufacturers. Nurses generated higher quality reports than doctors, pharmacists, and other professionals. Reporters of different occupations showed significant differences in the quality of the indicators Reporting time limit, Intervention ADR time, ADR termination time, ADR intervention measures, Original disease, and Cause of medication (P = 0.000).

Conclusions: The ADR data quality was poor in western China, and of lower quality than reported data from previous research in other regions. Improvements in the quality and availability of ADR reports are urgently needed.     

氧腹腔气体置换对腹腔镜胆囊切除术后胃肠动力影响的临床研究

为观察腹腔镜胆囊切除术（LC）及LC术后进行O2气置换对胃肠动力的影响。笔者对15例腹腔O2气体置换行LC的患者（O2置换组）与同期15例仅行LC的患者（常规LC组）进行对照，于术前、术后行胃电图检查及胃肠激素检测。结果示，O2置换组LC术后3d内全部病例气腹均未完全吸收，占100%;常规LC组LC术后3d内均完全吸收。O2置换组术后胃肠动力恢复慢;O2置换组LC术后气腹存留时限明显长于常规LC组（P<0.01）。提示术后腹腔气体存留可能不利于胃肠动力的恢复。     

癫(癎)患者先兆症状的研究

目的 探讨癫(癎)患者先兆症状的发生比例、临床表现,为正确诊断治疗癫(癎)提供依据.方法 回顾性研究1028例癫(癎)患者的临床资料,分析癫(癎)患者的先兆发生率、临床表现、脑电图和神经影像学结果.比较伴或不伴先兆的部分性发作癫(癎)患者的发病年龄、性别、脑电图、神经影像学的差异以及腹部先兆在颞叶内外侧癫(癎)出现比例的差异.结果 部分性癫(癎)725例,484例(66.8 % )出现先兆;全面性发作者303例,无一例患者出现先兆.64例患者出现2种或2种以上的先兆表现;14例出现持续性先兆的癫(癎)患者.1028例患者中脑电图异常547例(53.2 % ),影像学异常217例(21.1 % ).484例有先兆症状的患者中286例脑电图异常(59.1 % ),126例(26.0 % )影像学异常.伴或不伴先兆的部分性发作癫(癎)患者的首次发病年龄差异无统计学意义,腹部先兆在颞叶内外侧癫(癎)出现的比例差异有统计学意义(x2=170.877,P<0.01).结论 癫(癎)患者先兆症状多样,分析先兆症状对于癫(癎)分型、病灶定位以及合理治疗有指导意义.
