Elective Neck Dissection Versus Therapeutic Neck Dissection in Clinically Node-Negative Early Stage Oral Cancer: A Meta-analysis of Randomized Controlled Trials.

J Maxillofac Oral Surg 2022 Jun 6;21(2):340-349. Epub 2022 Jan 6.

Department of Surgery, Jawaharlal Nehru Cancer Hospital and Research Centre, Bhopal, India.

Introduction: Oral squamous cell carcinoma (OSCC) is characterized by a high risk of cervical lymph node metastasis; however, it is still not clear whether patients with early stage OSCC with clinical N0 neck should undergo elective neck dissection (END) at the time of primary tumor removal, or they should undergo a conservative approach of observation (OBS), with therapeutic neck dissection at the time of lymph nodal recurrence. We conducted a meta-analysis of randomized controlled trials (RCTs) that compared these two approaches.

Methods: PubMed and Scopus databases were searched for RCTs published in English language related to END and OBS in patients with early stage OSCC with clinical N0 neck. Read More

Assessment of gene expressions from squamous cell carcinoma of the head and neck to predict radiochemotherapy-related xerostomia and dysphagia.

Acta Oncol 2022 Jul 3;61(7):856-863. Epub 2022 Jun 3.

OncoRay - National Center for Radiation Research in Oncology, Faculty of Medicine and University Hospital Carl Gustav Carus, Technische Universität Dresden, Helmholtz-Zentrum Dresden - Rossendorf, Dresden, Germany.

Purpose: We tested the hypothesis that gene expressions from biopsies of locally advanced head and neck squamous cell carcinoma (HNSCC) patients can supplement dose-volume parameters to predict dysphagia and xerostomia following primary radiochemotherapy (RCTx).

Material And Methods: A panel of 178 genes previously related to radiochemosensitivity of HNSCC was considered for nanoString analysis based on tumour biopsies of 90 patients with locally advanced HNSCC treated by primary RCTx. Dose-volume parameters were extracted from the parotid, submandibular glands, oral cavity, larynx, buccal mucosa, and lips. Read More

Challenging airway in a postmandibulectomy patient for carcinoma of the buccal mucosa undergoing laparoscopic cholecystectomy.

BMJ Case Rep 2022 May 23;15(5). Epub 2022 May 23.

Department of Anaesthesia and Intensive Care, Post Graduate Institute of Medical Education and Research, Chandigarh, India.

Failure to secure the airway after administration of induction agent in a postmandibulectomy patient can lead to life-threatening complications; hence, recognising a difficult airway is of immense importance. Preoperative airway evaluation includes, but is not limited to, inter-incisor gap, modified Mallampati grading, neck movement, neck circumference, thyromental distance, sterno-mental distance, upper lip bite test and dental status. This case signifies the challenge encountered in securing the airway and the importance of thorough preoperative airway evaluation and preparedness before induction of anaesthesia in a postmandibulectomy patient for carcinoma of the buccal mucosa.

A combination of two regional flaps for the complex reconstruction after head and neck cancer surgery as an alternative approach during the COVID-19 pandemic: A case report.

Exp Ther Med 2022 May 1;23(5):364. Epub 2022 Apr 1.

Department of Physiology, 'Carol Davila' University of Medicine and Pharmacy, Bucharest 050474, Romania.

Since the COVID-19 pandemic outbreak, the medical systems were challenged by continuously increasing numbers of infections and faced critical issues when trying to find solutions for patients suffering from other diseases, including patients with head and neck cancers. Complex surgeries were delayed due to an acute deficit of specialized intensive care medical staff and equipment, which were redirected towards COVID-19 hospitalized cases, with irreversible consequences for the patients. In the present study, the case of locally advanced head and neck cancer was presented, which was treated radically during the heaviest wave of the COVID-19 pandemic in Romania using an alternative approach for immediate defect reconstruction.

Development of biocompatible nanoparticles of tizanidine hydrochloride in orodispersible films: In vitro characterization, ex vivo permeation and cytotoxic study on carcinoma cells.

Curr Drug Deliv 2022 Mar 21. Epub 2022 Mar 21.

Department of Pharmaceutical Sciences, M.D. University, Rohtak (124001), Haryana, India.

Background: The main limitations of the therapeutic effectiveness of tizanidine hydrochloride (TNZ) are its low bioavailability due to its tendency to undergo first-pass metabolism and short biological half-life. These factors make it an ideal candidate for formulating orally disintegrating films.

Methods: The fast-dissolving film of TNZ HCl was prepared by the solvent-casting method and characterized using scanning electron microscopy, FTIR and XRD, and evaluated for critical quality attributes for this type of dosage forms such as disintegration time, tensile strength, drug content, dissolution, and ex-vivo permeability.
