Hypothyroidism is a common disorder, potentially severe, often clinically ignored, easily diagnosed by laboratory tests, and highly treatable. It may cause chronic illnesses if left untreated. Saudi Society of Endocrinology and Metabolism (SSEM) assembled a panel of twelve endocrinologists with experience in thyroid diseases in adults and children and made up a task force. An initial concept proposal that included types of hypothyroidism, population, scope, and prevalence in Saudi Arabia was obtained. The proposal was divided into several topics discussed in February 2022. The panel approved that the consensus will include all types of hypothyroidism in Saudi Arabia, screening, diagnosis, management, and special population. A literature review was carried out. Most of the latest international guidelines were screened in Europe and USA. The literature search was completed in March 2022. They drafted a report that was distributed to the entire panel. Approval of the recommendations required consensus, defined as a majority approval. The recommendations were revised to accommodate any differences of opinion until a consensus was reached. Recommendations were finally formulated on April 2022. Subsequently, the panel reviewed and discussed the supporting rationale of the revised recommendations. This article presents these practical recommendations.

Instrumental detection of cystic duct stones during laparoscopic cholecystectomy

Hepatobiliary & Pancreatic Diseases International 2014年第2期13卷 215-218页

作者： amir Kambal Tomos Richards Harsha Jayamanne Zeyed Sallami ashraf Rasheed Taha Lazim Gwent Institute for Minimal Access Surgery Royal Gwent Hospital

Residual cystic duct stones (CDSs) after cholecystectomy have been recognized as a cause of post cholecystectomy pain. This study was undertaken to determine the incidence of CDSs during laparoscopic cholecystectomy(LC). A cohort of 330 consecutive patients (80 males and 250females) undergoing LC between November 2006 and May2010 was studied. Their age ranged between 16 and 88 years(median 50, IQR: 36.62). The data were prospectively collected of preoperative liver function tests, imaging, the presence of intraoperative CDSs, and common bile duct stones at on-table cholangiogram. CDSs were detected intraoperatively in 64 of the 330 patients (19%). Ultrasound failed to detect CDSs in any of these cases. Deranged liver function tests were noted in 73% of the patients with CDSs and in 57% without CDSs Common bile duct stones were detected in 9% (29) of the 330patients. CDSs occur commonly at routine cholecystectomy, and preoperative investigations are not helpful in their diagnosis As CDSs may lead to postoperative morbidity, they should be actively sought out during surgery if present.

Green Internet of things （loT） has been heralded as the ＂next big thing＂ waiting to be realized in energy-efficient ubiquitous computing. Green IoT revolves around increased machine-to-machine communications and encompasses energy-efficient wireless embedded sensors and actuators that assist in monitoring and controlling home appliances. Energy efficiency in home applications can be achieved by better monitoring of the specific energy consumption by the appliances. There are many wireless standards that can be adopted for the design of such embedded devices in loT. These communication technologies cater to different requirements and are classified as the short-range and long-range ones. To select the best communication method, this paper surveys various loT communication technologies and discusses the advantages and disadvantages to develop an energy monitoring system. An IoT device based on the Wi-Fi technology system is developed and tested for usage in the home energy monitoring environment. The performance of this system is then evaluated by the measurement of power consumption metrics. In the efficient deep-sleep mode, the system saves up to 0.3 W per cycle with an average power dissipation of less than 0.1 W/s.
