Actinomycosis of parotid gland after maxillary molar extraction, case report and review of literature.

Although actinomycosis is frequently seen in the cervicofacial region, it is very rare in the parotid gland. Furthermore, it can be confused with salivary gland malignancies in imaging. The most important underlying causes are cervicofacial trauma, tooth extraction history and poor oral hygiene.

Biphenotypic sinonasal sarcoma with PAX3/FOXO1 fusion.

Biphenotypic sinonasal sarcoma (BSNS), previously known as low-grade sinonasal sarcoma, is a rare tumour of the sinonasal tract, first described in 2012. It involves both myogenic and neural differentiation and is characterized by PAX3 rearrangement. MAML3 is the most frequent fusion partner of PAX3; however, its partner remains unidentified in a subset of cases.

The Evolution of Blood Flow Restricted Exercise.

The use of blood flow restricted (BFR) exercise has become an accepted alternative approach to improve skeletal muscle mass and function and improve cardiovascular function in individuals that are not able to or do not wish to use traditional exercise protocols that rely on heavy loads and high training volumes. BFR exercise involves the reduction of blood flow to working skeletal muscle by applying a flexible cuff to the most proximal portions of a person's arms or legs that results in decreased arterial flow to the exercising muscle and occluded venous return back to the central circulation. Safety concerns, especially related to the cardiovascular system, have not been consistently reported with a few exceptions; however, most researchers agree that BFR exercise can be a relatively safe technique for most people that are free from serious cardiovascular disease, as well as those with coronary artery disease, and also for people suffering from chronic conditions, such as multiple sclerosis, Parkinson's, and osteoarthritis.

Epithelial-myoepithelial carcinoma on lower lip and microinvasive verrucous carcinoma in vocal cord: Case report.

Epithelial-myoepithelial carcinoma is a biphasic low-grade malignant tumor, which represents approximately 1% of all salivary gland tumors. This tumor occurs mostly in the parotid gland, followed by submandibular gland and minor salivary glands. Women, mostly fifth to the eighth decade of life, are commonly affected.

An incidental giant preperitoneal fibrolipoma diagnosed during laparoscopic cholecystectomy.

Preperitoneal lipomas are rare in clinical practice. Here we report an unexpected diagnosis of a giant preperitoneal fibrolipoma detected intraoperatively during laparoscopic cholecystectomy in a 56-year-old woman. The mass was excised and a histopathological examination confirmed fibrolipoma.

Methods: his study consisted of conducted a cross-sectional analysis from a sample of community-dwelling older adults (N = 130) aged ≥67 years.

Pleomorphic adenoma of the larynx.

Pleomorphic adenoma (PA) is the most common benign neoplasm of the salivary glands. It usually occurs in major salivary glands, such as the parotid and submandibular glands. Occasionally, however, it occurs in the larynx.

Mobility limitations and fear of falling in non-English speaking older Mexican-Americans.

Objective: To determine whether older Mexican-Americans who cannot speak and/or understand spoken English have higher rates of mobility limitations or fear of falling than their English-speaking counterparts.

Design: We conducted a cross-sectional analysis of 1169 community-dwelling Mexican-Americans aged 72-96 years from the 2000-2001 wave of the Hispanic Established Population for the Epidemiological Study of the Elderly. Mobility limitations were defined as having a Short Physical Performance Battery score ≤9, and fear of falling by participant report of being somewhat, fairly, or very afraid of falling.

A Rare Cause of Prepubertal Gynecomastia: Sertoli Cell Tumor.

Prepubertal gynecomastia due to testis tumors is a very rare condition. Nearly 5% of the patients with testicular mass present with gynecomastia. Sertoli cell tumors are sporadic in 60% of the reported cases, while the remaining is a component of multiple neoplasia syndromes such as Peutz-Jeghers syndrome and Carney complex.

Hemodynamic responses and energy expenditure during blood flow restriction exercise in obese population.

Purpose: The study investigated the acute effects of different initial restrictive pressures (IRP; tightness of cuffs before inflation with air) on heart rate (HR), systolic (SBP) and diastolic blood pressure (DBP), rating of perceived exertion (RPE), respiratory exchange ratio (RER) and energy expenditure (EE) during constant-load upright cycling.

Methods: In a within subject study design, 34 obese men (age = 24·3, n = 18) and women (age = 23·1, n = 16) completed three cycling sessions (two blood flow restriction and one control sessions). The cycling exercise was performed with an external load of 1kp at 50 rpm for 20 min with 1-min rest after the 10th-min.

Kaposi sarcoma is usually associated with acquired immunodeficiency syndrome and involves lymphatic nodes and visceral organs. In this report, an 81-year-old man with epiglottic Kaposi sarcoma who screened negative for human immunodeficiency virus is presented.

Clinical significance of benign endometrial cells found in papanicolaou tests of Turkish women aged 40 years and older.

Background: Spontaneously exfoliated benign-appearing endometrial cells (BEC) on a Papanicolaou smear might indicate endometrial pathology in postmenopausal women, necessitating further investigation. A cut-off age of 40 years was included in the Bethesda System 2001 based on studies of clinical significance of endometrial cells in Pap smears in Western countries.

Aims: The purpose of this study was to determine the significance of age subgroup for women with a cytological diagnosis of BEC, regardless of menopausal status, in a retrospective cohort of Turkish women.

Tissue oxygenation, strength and lactate response to different blood flow restrictive pressures.

This study aimed to determine whether changes in initial restrictive pressures (IRP, tightness of the cuff before inflation with air) affect tissue oxygenation, lactate production and leg strength before, during and after knee extension exercises. The cuff was positioned on the right thigh, and the IRP of either 40-45 or 60-65 mmHg were applied randomly prior to inflating the cuff to the final restrictive pressure (the pressure reached after inflating the cuff with air). Subjects performed four sets (30, 15, 15 and 15 reps) of isotonic knee extensions with 1-min rest between sets.

Neuromuscular response to varying pressures created by tightness of restriction cuff.

Variation in regional body composition between genders may change the degree of pressure created by the tightness of cuff used during blood flow restriction training resulting in changes in the level of neuromuscular activation. This study investigates the effects of tightness of cuff and skin and subcutaneous fat thickness on electromyography (EMG) amplitude (RMS) and median frequency (MDF) during exercises and strength testing. Subjects performed knee-extension exercises with varying tightness of cuff while using EMG to measure changes in neuromuscular response.

Vascular restriction decreases EMG regularity during walking.

Prior research has found that the level of regularity in the output of numerous physiological systems is lowest in healthy young adults and higher in groups such as the elderly and those with various diseases. Vascular restriction has been found to stimulate exercise induced responses, including greater muscle activation, hypertrophy and increased strength. However, the time-dependent properties of muscular activation with vascular restriction have not previously been examined.
