Apocrine adenocarcinoma of the head and neck district: Our experience with two cases.

Introduction: Apocrine adenocarcinoma (AA) is a rare gland cancer that appears in the elderly, especially males. Surgery is considered the first option for the management of this tumor.

Case Presentation: We report two cases of AA that occurred at our Unit of Maxillofacial Surgery.

Evaluation of sarcopenia and sarcopenic obesity in patients affected by oral squamous cell carcinoma: A retrospective single-center study.

This retrospective single-center study aimed to evaluate the relevance of sarcopenia and sarcopenic obesity as negative prognostic factors in patients with oral squamous cell carcinoma (OSCC). The study was performed on patients who underwent oral squamous cell carcinoma resection surgery. Patients' demographic and clinical variables were collected at diagnosis (sex, age, height, weight, comorbidities, smoke and alcohol consumption, HPV positivity, TNM-stage) and corrected for known prognostic factors (age, body mass index, TNM-stage).

Effect of COVID-19 Italian Lockdown on Maxillofacial Trauma Related to Domestic Violence: A Retrospective Cohort Study.

Background: This retrospective study aims to identify the potential reasons for the increase in maxillofacial trauma from domestic violence in the first COVID-19 lockdown and propose some strategies that could be effective in fighting it during any future pandemic events. Materials and Methods: The study was conducted on patients with maxillofacial trauma who arrived at the Maxillofacial Unit of the Magna Graecia University of Catanzaro from 9 March to 3 May 2020, who were compared with those registered in the same period in 2019. Inclusion criteria were: patients of both sexes and admission diagnosed with maxillofacial trauma with or without bone fracture.

Extra-Nodal Lymphomas of the Head and Neck and Oral Cavity: A Retrospective Study.

: Lymphomas, both Hodgkin's and non-Hodgkin's lymphomas, are one of the most common cancers in the head and neck area. The extra-nodal variant of lymphoma is rare, but it is the most common non-Hodgkin's lymphoma (ENHL). Furthermore, it is difficult to diagnose due to its non-specific clinical and radiological features, which can mimic other benign or malignant clinical manifestations.

A Health Technology Assessment in Maxillofacial Cancer Surgery by Using the Six Sigma Methodology.

Squamous cell carcinoma represents the most common cancer affecting the oral cavity. At the University of Naples "Federico II", two different antibiotic protocols were used in patients undergoing oral mucosa cancer surgery from 2006 to 2018. From 2011, there was a shift; the combination of Cefazolin plus Clindamycin as a postoperative prophylactic protocol was chosen.

Application of DMAIC Cycle and Modeling as Tools for Health Technology Assessment in a University Hospital.

Background: The Health Technology Assessment (HTA) is used to evaluate health services, manage healthcare processes more efficiently, and compare medical technologies. The aim of this paper is to carry out an HTA study that compares two pharmacological therapies and provides the clinicians with two models to predict the length of hospital stay (LOS) of patients undergoing oral cavity cancer surgery on the bone tissue.

Methods: The six Sigma method was used as a tool of HTA; it is a technique of quality management and process improvement that combines the use of statistics with a five-step procedure: "Define, Measure, Analyze, Improve, Control" referred to in the acronym DMAIC.

On the integrability of Birkhoff billiards.

In this survey, we provide a concise introduction to convex billiards and describe some recent results, obtained by the authors and collaborators, on the classification of integrable billiards, namely the so-called Birkhoff conjecture.This article is part of the theme issue 'Finite dimensional integrable systems: new trends and methods'.
