Background: Clinical detection of structural narrowing of the upper airway may facilitate early recognition of obstructive sleep apnoea (OSA). To determine whether the craniofacial profile predicts the presence of OSA, the upper airway and craniofacial structure of 239 consecutive patients (164 Asian and 75 white subjects) referred to two sleep centres (Hong Kong and Vancouver) were prospective...

BACKGROUND Fluid accumulation in the neck during recumbency might narrow the upper airway (UA) and thereby contribute to its collapse in patients with obstructive sleep apnoea (OSA). It is hypothesised that acute fluid shifts from the legs to the upper body in healthy subjects would increase neck circumference and reduce the cross-sectional area of the UA (UA-XSA). METHODS In 27 healthy non-o...

BACKGROUND Head and neck injury is relatively common in Rugby Union. Despite this, strength and range-of-motion characteristics of the cervical spine are poorly characterised. The aim of this study was to provide data on the strength and range-of-motion of the cervical spine of professional rugby players to guide clinical rehabilitation. METHODS A cohort study was performed evaluating 27 play...

Objective: To test a prediction model for sleep apnea based on clinical and sociodemographic variables in a population suspected of having sleep disorders and submitted to polysomnography. Methods: We included 323 consecutive patients submitted to polysomnography because of the clinical suspicion of having sleep disorders. We used a questionnaire with sociodemographic questions and the Epworth ...

The objective of this research was to investigate the body measurements female Arabian chickens during laying phase. study utilized a sample 95 chickens, aged 94 weeks, which were housed in battery cages and for egg production. Direct taken on each chicken, with variables including weight, head circumference, beak length, comb height, neck back wing chest width, depth, upper thigh lower shank d...

background and objective: stop-bang questionnaire is a well-known obstructive sleep apnea (osa) screening tool. this study aimed to evaluate that patients with high probability of osa in stop-bang questionnaire meet the criteria for assessment by split-night polysomnography (psg). materials and methods: patients who were admitted to three sleep clinics and underwent full-night psg entered into ...

Purpose: Utilization of fiber optic video bronchoscope (F) alone vs. in combination with ultrasound (U + F) during tracheotomy procedures for patients with remarkable short necks. Materials and methods: Nineteen patients with short neck who required tracheotomy were enrolled to study. Tracheotomies were performed with Grigg’s technique. There was 9 patient in U + F group and 10 in F group. We g...

Background: Epicardial fat is an upper body visceral fat depot that may play a significant role in the development of adverse metabolic and cardiovascular risk profiles. There is a significant direct relationship between the amount of epicardial fat and general body adiposity (body mass index, BMI), but data regarding subcutaneous adiposity is limited. Objective: We conducted a study to deter...
