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.

Objective To compare the efficacy of using“distal acupoints only”vs.“local acupoints mainly combined with distal acupoints”in cases of acute low back pain(AlBP).Methods A total of 102 eligible patients aged 18–65 years with AlBP lasting less than 6 weeks will be randomized in a 1:1 ratio to the distal acupoints only group(DPOG)and the local acupoints mainly combined with the distal acupoints group(lPMG).During a 4-week treatment period,patients in the DPOG will receive acupuncture at distal acupoints only(Houxi[SI 3]and Yaotongxue[EX-UE 7])twice a week,while those in the lPMG group will receive acupuncture at local acupoints(mainly Shenshu[Bl 23]and Dachangshu[Bl 25])combined with distal points(Weizhong[Bl 40]).The patients in both groups will be evaluated at every session of treatment,and the follow-up will be performed for 3 *** primary outcome measure will be the change in AlBP intensity,assessed using visual analogue scale scores before and after *** secondary outcome measure will be the evaluation of functional disability using the Oswestry Disability *** This study compares the DPOG and lPMG to explore the feasibility of the DPOG in the treatment of AlBP.

This paper is a review of the history,development and efficacy of using dogs in wildlife studies and considers the use of dogs in the research and conservation of wild tigers(Panthera tigris linnaeus,1758).Using scat detection dogs,scent-matching dogs,law enforcement detection dogs and protection dogs are proven methods that can be effectively used on *** methods all take advantage of the dog’s extremely evolved sense of smell that allows them to detect animals or animal byproducts(often the focus of tiger studies).Dogs can be trained to communicate this information to their handlers.
