Hyalinizing Clear Cell Carcinoma of the Maxilla.

Hyalinizing clear cell carcinoma (HCCC) is a rare low-grade salivary gland tumor with distinctive clear cell morphology, accounting for < 1% of all salivary gland tumors. In the majority of cases, the tumor originates typically from the minor salivary glands in the oral cavity. A total of 155 cases of HCCCs from head and neck region have been reported in the literature until 2017, of which only 16 are of maxillary origin.

Robotic resection of lingual thyroglossal duct cyst in an infant.

Thyroglossal duct cysts (TDCs) are the most common congenital midline neck masses. Lingual TDC is a rare variant that emerges as an isolated cyst at the tongue base. Unlike conventional procedures aiming removal of cyst, duct, and hyoid bone via open surgical access, a transoral cystectomy is mostly sufficient in cases with lingual TDC.

Impact of age on intermittent hypoxia in obstructive sleep apnea: a propensity-matched analysis.

Purpose: To determine independent relationship of aging with chronic intermittent hypoxia, we compared hypoxia-related polysomnographic variables of geriatric patients (aged ≥ 65 years) with an apnea-hypopnea index (AHI)-, gender-, body mass index (BMI)-, and neck circumference-matched cohort of non-geriatric patients.

Methods: The study was conducted using clinical and polysomnographic data of 1280 consecutive patients who underwent complete polysomnographic evaluation for suspected sleep-disordered breathing (SDB) at a single sleep disorder center. A propensity score-matched analysis was performed to obtain matched cohorts of geriatric and non-geriatric patients, which resulted in successful matching of 168 patients from each group.

Can Statistical Machine Learning Algorithms Help for Classification of Obstructive Sleep Apnea Severity to Optimal Utilization of Polysomnography Resources?

Objectives: The goal of this study is to evaluate the results of machine learning methods for the classification of OSA severity of patients with suspected sleep disorder breathing as normal, mild, moderate and severe based on non-polysomnographic variables: 1) clinical data, 2) symptoms and 3) physical examination.

Methods: In order to produce classification models for OSA severity, five different machine learning methods (Bayesian network, Decision Tree, Random Forest, Neural Networks and Logistic Regression) were trained while relevant variables and their relationships were derived empirically from observed data. Each model was trained and evaluated using 10-fold cross-validation and to evaluate classification performances of all methods, true positive rate (TPR), false positive rate (FPR), Positive Predictive Value (PPV), F measure and Area Under Receiver Operating Characteristics curve (ROC-AUC) were used.

Estimation of cardiovascular disease from polysomnographic parameters in sleep-disordered breathing.

We aimed to illustrate the causal relationships between cardiovascular diseases (CVDs) and various polysomnographic variables, and to develop a CVD estimation model from these variables in a population referred for assessment of possible sleep-disordered breathing (SDB). Clinical and polysomnographic data of 1162 consecutive patients with suspected SDB whose comorbidity status was known, were reviewed, retrospectively. Variable selection was performed in two steps using univariate analysis and tenfold cross validation information gain analysis.

Spindle Cell Carcinoma of the Larynx: A Confusing Diagnosis for the Pathologist and Clinician.

Laryngeal spindle cell carcinoma (SpCC) is an uncommon subtype of squamous cell carcinoma which represents 0.5% of all laryngeal squamous cell carcinomas. It is a biphasic tumor consisting of the combination of a malignant mesenchymal spindle cell component and a squamous cell component that includes dysplasia, carcinoma in situ, or invasive carcinoma.

The influence of multilevel upper airway surgery on CPAP tolerance in non-responders to obstructive sleep apnea surgery.

The aim of this study was to evaluate the influence of multilevel upper airway surgery on subsequent continuous positive airway pressure (CPAP) use and tolerance in patients with moderate to severe obstructive sleep apnea (OSA). The study cohort enrolled 67 consecutive patients, who underwent septoplasty plus modified uvulopharyngopalatoplasty (mUPPP) with or without modified tongue base suspension (mTBS) due to CPAP intolerance, and who had residual OSA requiring CPAP therapy [non-responders to surgery, apnea-hypopnea index (AHI) >15 events/h] that had been confirmed by control polysomnography at the sixth month postoperatively. A questionnaire including questions on postoperative CPAP use, problems faced during CPAP use after the surgery, change in OSA symptoms, and satisfaction with the surgery was designed, and filled through interviews.

Pediatric sinonasal rhabdomyosarcoma: A case report.

Pediatric sinonasal rhabdomyosarcoma (PSR) is a rare condition, with a limited number of previously reported cases.

Internal Jugular Vein Thrombosis following Oropharyngeal Infection.

Internal jugular vein thrombosis (IJVT) is a rare condition which may lead to life-threatening complications such as sepsis and pulmonary embolism. Prolonged central venous catheterization, intravenous (IV) drug use, trauma, and radiotherapy are the most frequent causes of the IJVT. IJVT that develops after the oropharyngeal infection is a quite rare situation today.

The relationship between the duration of obstructive respiratory events and outcomes of multilevel upper airway surgery in patients with obstructive sleep apnea.

We aimed to examine whether the duration of respiratory events and related oximetric values are associated with outcomes of multilevel upper airway surgery in patients with moderate-severe obstructive sleep apnea (OSA). The records of patients with a preoperative apnea-hypopnea index (AHI) >15 events/h, who underwent uvulopharyngopalatoplasty plus tongue base suspension with or without septoplasty between 2012 and 2014, were reviewed retrospectively. If the postoperative 6th month AHI was <20 events/h with at least a 50 % reduction from preoperative rates, the outcome of surgery was regarded as successful, otherwise, as failure.

Predicting the outcome of modified tongue base suspension combined with uvulopalatopharyngoplasty.
