An anatomical study of the pharyngeal plexus: Application to avoiding postoperative dysphagia following anterior approaches to the cervical spine.

Clin Anat 2021 Sep 18. Epub 2021 Sep 18.

Department of Neurosurgery, Tulane Center for Clinical Neurosciences, Tulane University School of Medicine, New Orleans, LA, USA.

Objective: We aimed to localize the pharyngeal branches of the pharyngeal plexus to preclude postoperative complications such as dysphagia resulting from injury to those branches.

Patients And Methods: Cranial nerves IX and X and the sympathetic trunk were dissected on ten sides in the necks of enbalmed adult cadavers of European descent to identify the pharyngeal branches so that anatomical landmarks could be identified and injury thereby avoided.

Results: In all sides, the pharyngeal branches originated from the glossopharyngeal and vagus nerves and the superior cervical ganglion and entered the posterior pharyngeal wall at the C2 to C4 levels within 10 mm medial to the greater horn of the hyoid bone. Read More

Radiological comparison of penetrating endplate trajectory versus anterior bicortical trajectory for sacral pedicle screw insertion in posterior lumbosacral interbody fusion.

J Orthop Sci 2021 Sep 13. Epub 2021 Sep 13.

Department of Orthopaedic Surgery, National Hospital Organization, Murayama Medical Center, Musashimurayama, Tokyo, Japan.

Background: The bicortical or tricortical fixation technique with purchase into the anterior sacral wall or promontory has been recommended to achieve rigid sacral pedicle screw fixation, which carries the potential risk of neurovascular injuries. The penetrating endplate screw (PES) technique was proposed as an alternative screw trajectory to facilitate both strong fixation and safety. However, there has been no report on the practical significance of using the PES technique. Read More

J Thorac Dis 2021 Aug;13(8):5314-5330

Division of Pulmonary, Allergy, and Critical Care Medicine, The University of Alabama at Birmingham, Birmingham, AL, USA.

Percutaneous tracheostomy and gastrostomy are some of the most commonly performed procedures at bedside in the intensive care unit. While they are generally considered safe, they can be associated with numerous short and long-term complications, many of which can occur long after their placement and cause significant morbidity. Performers of these procedures should possess a comprehensive understanding of procedural indications and contraindications, and know how to recognize and manage complications that may arise.

State of the art: percutaneous tracheostomy in the intensive care unit.

J Thorac Dis 2021 Aug;13(8):5261-5276

Division of Pulmonary & Critical Care Medicine, Section of Interventional Pulmonology, University of Maryland School of Medicine, Baltimore, MD, USA.

Percutaneous tracheostomy is a commonly performed procedure for patients in the intensive care unit (ICU) and offers many benefits, including decreasing ICU length of stay and need for sedation while improving patient comfort, effective communication, and airway clearance. However, there is no consensus on the optimal timing of tracheostomy in ICU patients. Ultrasound (US) and bronchoscopy are useful adjunct tools to optimize procedural performance. Read More

Wall shear stress mapping for human femoral artery based on ultrafast ultrasound vector Doppler estimations.

Med Phys 2021 Sep 15. Epub 2021 Sep 15.

Department of Biomedical Engineering, National Cheng Kung University, Taiwan.

An approach to giant neonatal hydrocolpos with normally sited anus - Diagnosis and management including a novel one stage operation.

J Pediatr Urol 2021 Aug 8. Epub 2021 Aug 8.

Department of Paediatric Surgery, PSG Institute of Medical Sciences and Research, Coimbatore, Tamilnadu, India.

Introduction: Giant non cloacal neonatal hydrocolpos is a rare entity where early recognition of the underlying cause and drainage of the distended vagina is paramount. Conventionally, immediate management has been by abdominal tube vaginostomy or, in urogenital sinus by vaginal clean intermittent catheterisation (CIC). Though effective in providing temporary relief, the abdominal tube vaginostomy is replete with complications, making it imperative to search for alternatives. Read More
