BACKGROUND: Dentists are an overlooked group of prescribers but are responsible for up to 10% of antibiotic prescriptions written in the US annually, a majority of which are for prophylaxis. Dental prophylaxis in orthopedic patients has been an area of confusion, with discordance among societal guidelines. In 2020, an Antimicrobial Stewardship (AS) group spear-headed a collaborative effort between dental, orthopedic surgery, and infectious diseases specialties to develop a protocol for the use of dental antibiotic prophylaxis for patients with total joint replacements (TJR) based on the most current American Dental Association/American Academy of Orthopaedic Surgeons (ADA/AAOS) statement...

Calcium phosphate cement remains the choice biomaterial for cranial reconstruction and augmentation in pediatric patients after 90% completion of cranial growth, especially compared with other nonallograft alternatives. While trauma to the site of calcium phosphate augmentation is a known risk for cement fracture, subsequent micro-fragmentation and sequestration of the cement beneath the fracture site can produce a localized inflammatory reaction that requires surgical intervention to adequately address. The authors present the course of a patient undergoing a prolonged inflammatory reaction to calcium phosphate micro-fragmentation after trauma to the site of previous augmentation performed to mend bitemporal hollowing...

Myasthenia gravis is a rare autoimmune condition that affects postsynaptic cholinergic receptors, resulting in symptoms of muscular fatigue. Clinical signs could be subtle and variable, often leading to many differentials. This leads to inappropriate tests being performed and a delay in diagnosis. Although ocular signs are more common, it may rarely present as bulbar palsy. Our patient, in her 30s, was referred to the emergency department after six months of symptom onset when she was discovered to be at a high risk of silent aspiration...

Hirschsprung disease (HSCR) is a rare congenital intestinal disease that occurs in 1 in 5,000 live births. HSCR is characterized by the absence of ganglion cells in the myenteric and submucosal plexuses of the intestine. Most patients present during the neonatal period with the first meconium passage delayed beyond 24 h, abdominal distension and vomiting. Syndromes associated with HSCR include trisomy 21, Mowat-Wilson syndrome, congenital central hypoventilation syndrome, Shah-Waardenburg syndrome and cartilage-hair hypoplasia...

OBJECTIVES: To study clinical disease outcomes in both human and animal models to understand the pathogenicity of omicron compared to the delta variant. METHODS: In this cross-sectional observational study, clinical outcomes of adults who tested positive at 2 testing centres in Delhi National Capital Region between January 2022 and March 2022 (omicron-infected; N = 2998) were compared to a similar geographical cohort (delta-infected; N = 3292)...

BACKGROUND: Current understanding of medical debt among various income ranges and insurance carriers is limited. We analyzed median household incomes, insurance carriers, and medical debt of plastic surgery patients at a major metropolitan children's hospital. METHODS: A retrospective chart review for zip codes, insurance carriers, and account balances was conducted for 2018-2021. All patients were seen by members of the Division of Pediatric Plastic Surgery at Ann and Robert H...

Parenteral nutrition (PN) prevents starvation and supports metabolic requirements intravenously when patients are unable to be fed enterally. Clinically, infants are frequently provided PN in intensive care settings along with exposure to antibiotics (ABX) to minimize infection during care. Unfortunately, neonates experience extremely high rates of hepatic complications Adult rodent and piglet models of PN are well-established, but neonatal models capable of leveraging the considerable transgenic potential of the mouse remain underdeveloped...

INTRODUCTION: The mechanism underlying radiation-induced gut microbiota dysbiosis is undefined. This study examined the effect of radiation on the intestinal Paneth cell α-defensin expression and its impact on microbiota composition and mucosal tissue injury and evaluated the radio-mitigative effect of human α-defensin 5 (HD5). METHODS: Adult mice were subjected to total body irradiation, and Paneth cell α-defensin expression was evaluated by measuring α-defensin mRNA by RT-PCR and α-defensin peptide levels by mass spectrometry...

BACKGROUND: The American Board of Plastic Surgery (ABPS) has collected data on cosmetic surgery from member surgeons since 2003. These data offer valuable information on national trends in clinical practice. OBJECTIVES: The present study was performed to analyze trends in rhinoplasty over the last decade. METHODS: Tracer data were compared between two cohorts 2012-2016 (early cohort "EC") and 2017-2021 (recent cohort "RC"). Data included patient demographics and surgical techniques...

Surgical treatment of velopharyngeal insufficiency (VPI) after primary palatoplasty poses a difficult challenge in cleft care management. Traditional treatment options have shown improved speech outcomes but oftentimes lead to airway obstruction by constriction of the posterior pharynx. The buccinator myomucosal flap is an alternative flap used for VPI correction that re-establishes palatal length and velar sling anatomy by recruiting tissue from the buccal mucosa and buccinator muscle. We present innovative modifications to the original buccinator myomucosal flap by performing the procedure in one stage without a mucosal bridge, incorporating full-thickness buccinator muscle during flap elevation, and placement of bilateral buccal fat flaps...

BACKGROUND: Prior reports have highlighted disparities in healthcare access, environmental conditions, and food insecurity between Black and White populations in the United States. However, limited studies have explored racial disparities in postoperative complications, particularly reconstructive flap surgeries. METHODS: Cases of flap reconstruction based on named vascular pedicles were identified in the American College of Surgeons National Surgical Quality Improvement Program database and grouped into 3 time periods: 2005 to 2009, 2010 to 2014, and 2015 to 2019...

We discuss a promising solid-state system that emits single photons at room temperature in the blue-green range, making it an attractive candidate for quantum communications in free space and underwater. The active element is a core-shell ZnSe tapered nanowire embedding a single CdSe quantum dot grown by molecular beam epitaxy. A patterned substrate enables a comprehensive study of a single nanowire using various methods. Our source shows potential for achieving a total brightness of 0.17 photon per pulse and anti-bunching with g(2) (0) < 0...
