Vocal Folds Leukoplakia: The Efficacy of Vitamin A in the Initial Treatment.

 Laryngeal leukoplakia corresponds to a white lesion in the mucosa developed by the deposit of keratin in the epithelium, potentiated by chronic smoking. It is considered a preneoplastic lesion. Surgery is the most adopted treatment; however, non-surgical treatment is advocated by some authors.

Effect of Aging on the Vocal Muscle.

Introduction: Sarcopenia is a common and natural condition in the elderly, and leads to loss of muscle mass and function. In the presbylarynx there is atrophy of the vocal folds, however the degree of vocal muscle atrophy is poorly studied and the results are contradictory.

Aims: The aim of this study was to evaluate the effect of aging on the vocal muscle (thyroarytenoid muscle).

Is there a relationship between diet quality and bone health in elderly women? A cross-sectional study.

Objective: To evaluate whether there is a relationship between diet quality and bone health in a group of elderly Brazilian women.

Methods: A cross-sectional study was performed with 105 elderly women. Participants were evaluated regarding diet quality (good, needing improvement, and poor) and its relationship with bone mineral density (BMD), bone-specific alkaline phosphatase (BSAP), and C-telopeptide (CTX).

Does Abrupt Weight Loss Caused by Bariatric Surgery Compromise the Voice in Women?

Objective: To evaluate vocal symptoms, voice characteristics and videolaryngoscopy in obese women before and after bariatric surgery.

Methods: Obese patients (18 to 59 years old), candidates for bariatric surgery were recruited. Evaluation times: T1 (preoperative), T2 (after six months), T3 (after 12 months).

An estimate of the incidence and prevalence of laryngeal papillomatosis in São Paulo State (Brasil).

Background: Recurrent laryngeal papillomatosis, caused by the Human Papilloma Virus, has a significant economic impact worldwide and there are no epidemiological data of this disease in Brasil.

Objective: The objective of the study was to estimate the incidence and prevalence of laryngeal papillomatosis of some otorhinolaryngology centers in São Paulo State (Brasil).

Methods: A questionnaire containing data on the number of new and follow-up cases diagnosed with laryngeal papillomatosis was sent to the Otorhinolaryngology services (n=35) of São Paulo State (Brasil).

Is There an Association With Spino-Pelvic Relationships and Clinical Outcome of Type A Thoracic and Lumbar Fractures Treated Non-Surgically?

Background: The objective was to evaluate if there is an association of the spino-pelvic relationships and the global spinal alignment with the outcome of AO type A injuries treated nonsurgically.

Methods: This is a retrospective case series. Patients treated nonsurgically for AOSpine type A fractures (T1-L5) with at least 1 year follow-up identified.

Laryngeal and vocal alterations after thyroidectomy.

Introduction: Dysphonia is a common symptom after thyroidectomy.

Objective: To analyze the vocal symptoms, auditory-perceptual and acoustic vocal, videolaryngoscopy, the surgical procedures and histopathological findings in patients undergoing thyroidectomy.

Methods: Prospective study.

Aging voice and the laryngeal muscle atrophy.

Objectives/hypothesis: To study by means of morphometric measurements the severity of vocal muscle atrophy in the elderly.

Study Design: Cadaver study.

Setting: Universidade Estadual Paulista (UNESP), Botucatu Medical School, Brazil.

Hyaluronic acid behavior in the lamina propria of the larynx with advancing age.

Objectives: To analyze the hyaluronic acid behavior in the lamina propria of the larynx with advancing age.

Study Design: Prospective study.

Setting: UNESP-Univ Estadual Paulista, Botucatu Medical School, Brazil.

Perceptual and acoustic parameters of vocal nodules in children.

Unlabelled: Vocal nodules constitute the major cause of dysphonia during childhood. Auditory-perceptual and acoustic vocal analyses have been used to differentiate vocal nodules from normal voice in children.

Purpose: To study the value of auditory-perceptual and acoustic vocal analyses in assessments of children with nodules.

Differential morphofunctional characteristics and gene expression in fast and slow muscle of rats with monocrotaline-induced heart failure.

Heart failure (HF) is characterized by limited exercise tolerance, skeletal muscle atrophy, a shift toward fast muscle fiber, and myogenic regulatory factor (MRF) changes. Reactive oxygen species (ROS) also contribute to target organ damage in this syndrome. In this study, we investigated and compared morphofunctional characteristics and gene expression in Soleus (SOL--oxidative and slow twitching muscle) and in Extensor Digitorum Longus (EDL--glycolytic and fast twitching muscle) during HF.
