Navigating a challenging airway: An ultrasound-guided approach to urgent tracheostomy.

Objectives: Airway compromise in neck cancer patients with distorted anatomy has been a challenge for head and neck surgeons. To the best of our knowledge, the use of ultrasound has not been reported as an adjunct prior to an awake urgent tracheostomy in these types of patients. Our main objective is to provide an additional tool for identification of vital neck structures in preparation for an awake tracheostomy.

Pediatric Free Flaps: Indications, Considerations, and Follow-up.

Free tissue transfer is a very effective reconstructive technique for challenging defects of the head and neck and in many cases the gold standard for congenital facial paralyses and composite defects. Although its use in the pediatric population is not new and the success rates are comparable to those in adults, there is still a lack of information about its applications in children. This study aims to review the indications for use and discuss the anatomic considerations that may influence surgical complexity and long-term outcomes in the developing craniofacial skeleton.

Incidental Tracheocele as an Unusual Presentation of Pneumomediastinum in the Trauma Setting.

BACKGROUND Tracheocele are rarely encountered air cysts formed due to tracheal wall outpouching through a weak vantage point. The majority are acquired in the adult population and are associated with conditions that weaken the tracheal wall. Most tracheoceles are diagnosed incidentally since many are asymptomatic or present with nonspecific symptoms.

uses amino acids associated with gut microbial dysbiosis in a subset of patients with diarrhea.

The gut microbiota plays a critical role in pathogen defense. Studies using antibiotic-treated mice reveal mechanisms that increase susceptibility to infection (CDI), but risk factors associated with CDI in humans extend beyond antibiotic use. Here, we studied the dysbiotic gut microbiota of a subset of patients with diarrhea and modeled the gut microbiota of these patients by fecal transplantation into germ-free mice.
