Background: Early cholecystectomy has been recommended for patients with acute cholecystitis and gallstone pancreatitis. However, patients with pancreaticobiliary malignancy may present acutely with similar symptoms. We hypothesize that the diagnoses of these malignancies may potentially be delayed as an unintended consequence of expedited cholecystectomies. This study reviews a cohort of patients who underwent pancreaticoduodenectomy (PD) to identify those who underwent a separate cholecystectomy before their PD. Methods: We retrospectively reviewed 162 PDs performed between 2012 and 2022. Data collected included: demographics, disease etiology and the presence of cholelithiasis. We identified patients who had a previous cholecystectomy and the time elapsed before PD as well as procedures done during the interval. We reported detailed case summaries on those patients who had a cholecystectomy within 1 year of PD. Results: In the entire cohort, mean age was 65 years, 54% were males, and 83% had a malignant reason for PD. Thirty-one patients had cholelithiasis with 23 (14%) patients having had previous cholecystectomy. Six patients had cholecystectomy within 1 year of PD. They had the following malignancies: ampullary—3, pancreas—1, cholangiocarcinoma—1 and neuroendocrine—1. Four of these patients had expedited cholecystectomy on their index hospital admission and were later found to have a periampullary malignancy with further work up. Conclusions: Pancreaticobiliary malignancies can be difficult to diagnose, and surgeons should not overlook these potential diagnoses when considering expedited cholecystectomy. Future studies in large cohorts are needed to identify high risk candidates who should undergo more detailed testing to exclude malignancy before proceeding with cholecystectomy.

The authors report a case of deficient sensory neuropathy secondary to vitamin B12 deficiency, diagnosed in the neurology department of the Sino-Central African Friendship University Hospital in Bangui. The diagnosis was made possible by electroneuromyography which showed subclinical neurological damage associated with hematological damage (anemia). Through this observation, we recall the diagnostic criteria of the disease in a context of difficult medical practice. .

目的:采用静息态功能磁共振成像(rs-f MRI)技术探究杨氏絮刺火罐治疗湿疹瘙痒的临床疗效和中枢机制。方法:50例湿疹瘙痒患者纳入观察组,50名健康受试者纳入对照组。对照组不行任何干预;观察组于大椎及双侧曲池、血海、三阴交行杨氏絮刺火罐治疗,每周1次,共治疗6周。比较观察组治疗前后12项瘙痒严重程度评估量表(12-PSS)、湿疹面积及严重程度(EASI)、皮肤病生活质量指数(DLQI)、匹兹堡睡眠质量指数(PSQI)和焦虑自评量表(SAS)评分。观察组治疗前后及对照组入组时均接受rs-fMRI扫描并进行局部一致性(ReHo)分析,将差异脑区ReHo值与上述量表评分进行相关性分析。结果:与治疗前比较,观察组治疗后12-PSS、EASI、DLQI、PSQI、SAS评分均降低(P<0.01,P<0.05)。与对照组比较,观察组治疗前右侧尾状核、右侧颞中回、右侧眶部额上回、右侧丘脑、左侧角回ReHo值增高(P<0.001);与治疗前比较,观察组治疗后上述脑区ReHo值下降(P<0.001)。与对照组比较,观察组治疗前左侧颞中回、左侧顶上小叶、左侧补充运动区ReHo值下降(P<0.001);与治疗前比较,观察组治疗后上述脑区ReHo值增高(P<0.001)。治疗前,观察组左侧补充运动区ReHo值与12-PSS评分呈正相关(r=0.432,P=0.004);右侧眶部额上回ReHo值与PSQI评分呈负相关(r=-0.318, P=0.04)。治疗后,观察组左侧顶上小叶ReHo值与12-PSS评分呈正相关(r=0.384,P=0.012)。结论:湿疹瘙痒患者多个参与刺激反应、情绪调节、行为控制、注意力等功能的脑区存在活动异常。杨氏絮刺火罐能有效改善湿疹患者瘙痒症状和皮肤损害,其作用机制可能和逆转瘙痒所导致的脑区功能活动异常有关。
