Exclusive Endonasal Endoscopic Removal of an Old, Retained, Displaced Tooth Fragment Causing Isolated, Refractory, Chronic Maxillary Sinusitis.

Unlabelled: Inadvertent displacement of tooth fragments into the maxillary sinus is a known complication of dental extraction that can be managed instantaneously or soon thereafter through conventional techniques like Caldwell-Luc, alveolar crestal, and lateral approaches. However, if the event remains unidentified or ignored, recalcitrant sinus infection and intra-sinus tooth migration may result. The situation can then be difficult to investigate and treat.

The Effects of Electronic Cigarettes on Oral Microbiome and Metabolome in 3D Tissue-Engineered Models.

Background And Aim: Recent studies have shown that electronic cigarettes (ECs) use disrupts the oral microbiome composition and diversity, impairing the metabolic pathways of the mucosal cells.

Objectives: To evaluate effects of prolonged intubation in children through endoscopic screening of the laryngotracheal airway.

Methods: In this cross-sectional pilot project, children (2 months-12 years) successfully extubated following prolonged intubation were selected, irrespective of having symptoms, for a 1-time flexible nasolaryngoscopy at third to sixth month post-extubation (follow-up window).

The effect of COVID-19 pandemic on routine surgical turnover in otolaryngology: a retrospective analysis of service dynamics utilizing finalized, cumulative data from a tertiary-care teaching institute in India.

Objective: To ascertain the effect of coronavirus (COVID-19) pandemic on routine (non-COVID) Otolaryngology and Head-Neck Surgery (ORL-HNS) turnover in a tertiary-care teaching institute, utilizing the cumulated, finalized dataset one year after the pandemic ceased to be a "public health emergency of international concern".

Methodology: In this retrospective analysis, annual routine turnover in the ORL-HNS categories (otology, rhinology/skull-base, head-neck/airway, emergency, miscellaneous) for the COVID-period (2020-21) were individually compared with pre-COVID (2017-19) data. Subsequently, categorical turnovers, along with the major surgeries in each category, were compared trimester-wise in the COVID-period.

TBK1 Reprograms Metabolism in Breast Cancer: An Integrated Omics Approach.

Metabolic rewiring is required for cancer cells to survive in harsh microenvironments and is considered to be a hallmark of cancer. Specific metabolic adaptations are required for a tumor to become invasive and metastatic. Cell division and metabolism are inherently interconnected, and several cell cycle modulators directly regulate metabolism.

Presentation and Management of Facial Fractures: An Experience from a Tertiary-Care Teaching Institute in India.

Background: Most tertiary-care teaching institutes in low and middle-income nations lack dedicated oral and maxillofacial surgery (OMFS) units in the emergency trauma centers. Consequently, most facial fractures need to be managed in the otolaryngology and head-neck surgery (ORL-HNS) setup.

Objectives: To present a study on a series of patients with facial fractures attending the emergency and outpatient departments of ORL-HNS in a tertiary-care teaching institute in India that lacked the facility of OMFS in its emergency trauma center.

Hepatic stearoyl-CoA desaturase-1 deficiency induces fibrosis and hepatocellular carcinoma-related gene activation under a high carbohydrate low fat diet.

Stearoyl-CoA desaturase-1 (SCD1) is a pivotal enzyme in lipogenesis, which catalyzes the synthesis of monounsaturated fatty acids (MUFA) from saturated fatty acids, whose ablation downregulates lipid synthesis, preventing steatosis and obesity. Yet deletion of SCD1 promotes hepatic inflammation and endoplasmic reticulum stress, raising the question of whether hepatic SCD1 deficiency promotes further liver damage, including fibrosis. To delineate whether SCD1 deficiency predisposes the liver to fibrosis, cirrhosis, and hepatocellular carcinoma (HCC), we employed in vivo SCD1 deficient global and liver-specific mouse models fed a high carbohydrate low-fat diet and in vitro established AML12 mouse cells.

Like Versus Unlike: Closure of a Moderate-sized Circular Tissue Defect Following Wide Local Excision of Primary Cutaneous Squamous Cell Carcinoma of Face by Rhombic Transposition Flap with Modification.

Closure of a circular tissue defect in the head-neck-face region is challenging because most transposition flaps are rhombic or triangular. For a tension-less closure, both rhombic transposition flap and the circular tissue defect need to be engineered maintaining strict geometric calculations. The present illustration demonstrates a modified rhombic transposition flap with greater freedom in rotation and mobility for closing a moderate-sized circular defect resulting from wide local excision of cutaneous squamous cell carcinoma in the mid-face.
