Double naso-enteric tubes stenting in afferent limb syndrome with concomitant proximal efferent limb obstruction after loop gastrojejunostomy bypass: a case report.
J Surg Case Rep
December 2024
Department of Surgery, Phramongkutklao Hospital, Thung Phaya Thai, Ratchathewi, Bangkok 10400, Thailand.
Endoscopic or fluoroscopic guided naso-enteric placement for stenting and decompression has been used in mechanical enteric limb obstruction after gastrectomy or gastric bypass surgery. However, the use of double naso-enteric tube for treatment of multiple enteric limbs obstruction has not been described to date. We present a 61-year-old female with afferent limb syndrome with concomitant efferent limb obstruction which caused by kinking of anastomosis after loop gastrojejunostomy for benign gastric outlet obstruction.

Article Synopsis
- The study aimed to evaluate the characteristics of upper limb arteriovenous fistulas used for hemodialysis in patients, focusing on their Doppler ultrasound results.
- Conducted at Yaoundé University Teaching Hospital, it included 41 dialysis patients and found that a significant number had complications such as stenosis and low flow volume.
- Key findings showed that over half of the fistulas were stenosed, with common complications including aneurysms and reverse flow, highlighting a high prevalence of vascular issues in these access points.
An Efficient Framework for Personalizing EMG-Driven Musculoskeletal Models Based on Reinforcement Learning.
IEEE Trans Neural Syst Rehabil Eng
October 2024
This study aimed to develop a novel framework to quickly personalize electromyography (EMG)-driven musculoskeletal models (MMs) as efferent neural interfaces for upper limb prostheses. Our framework adopts a generic upper-limb MM as a baseline and uses an artificial neural network-based policy to fine-tune the model parameters for MM personalization. The policy was trained by reinforcement learning (RL) to heuristically adjust the MM parameters to maximize the accuracy of estimated hand and wrist motions from EMG inputs.

September 2024
General Surgery, Lebanese Hospital Geitaoui University Medical Center, Beirut, LBN.
Article Synopsis
- Meckel's diverticulum (MD) is a common birth defect in the gastrointestinal tract that affects about 2% of people, resulting from the incomplete closure of the vitelline duct, and it can cause complications like obstruction and hemorrhage.
- Diagnosing MD can be tricky due to low sensitivity of imaging techniques, which makes understanding and accurately diagnosing it important for managing potential complications.
- The text presents two cases: one involving a 73-year-old male requiring surgery for ileostomy closure who was found to have MD during surgery, and another involving a 40-year-old female with severe abdominal pain related to an inflamed MD with a fish bone lodged inside, highlighting the ongoing debate over whether or not to resect
Dropping Objects in Carpal Tunnel Syndrome: Clinical and Electrophysiological Features.
Cureus
August 2024
Neurology and Clinical Neurophysiology, Istanbul University, Istanbul Faculty of Medicine, Istanbul, TUR.
Background Dysfunction in both afferent sensory and efferent motor components of the median nerve may contribute to the manifestation of the symptom of dropping objects (DO) in carpal tunnel syndrome (CTS). The objective of this study was to compare the clinical and electrophysiological characteristics of CTS patients with dropping objects (wDO) and those without dropping objects (w/oDO). The study evaluated the correlation between DO symptoms and median partial conduction block, as well as the reduction in median motor conduction velocity at the wrist.
