2. Is there a relationship between tonsil volume and the success of pharyngeal surgery among adult patients with obstructive sleep apnea?
Abstract Objectives: Hypertrophic palatine tonsils play a role in the blockage of the upper airway, one of the known causes of Obstructive Sleep Apnea (OSA). Therefore, it is possible that there is an association between tonsil size and the success of pharyngeal surgery during OSA treatment. The main objective of this study was to evaluate the relationship

3. Effects of vestibular rehabilitation in the management of patients with and without vestibular migraine
Abstract Objective: Vestibular Migraine (VM) is the second most common cause in patients with vertigo. Patients with VM complain about vestibular symptoms during a headache attack or during the period between attacks. Vestibular Rehabilitation (VR), an exercised based therapy to treat dizziness and balance dysfunction has been shown to be effective in vesti

4. Cadaveric study of anatomical measurement of isthmus parameters of lumbar spine to guide cortical bone screw placement
SUMMARY OBJECTIVE: To reduce surgical exposure and improve accuracy, this study evaluated the anatomical distance parameter D (including D1, D2, and D3) of the lumbar isthmus for cortical bone screw insertion. METHODS: A total of 25 structurally complete lumbar dry specimens were used for lumbar anatomy measurements. The six cadaver specimens were divided

5. AOPs são o futuro da ecotoxicologia?
ARE AOPs THE FUTURE OF ECOTOXICOLOGY? AOPs (Adverse Outcome Pathways) were introduced in the field of ecotoxicology due to the need of replacement of the classic system for assessing adverse results (considering only the mortality of organisms exposed to certain substances or mixtures) to a predictive system based on the measurement of biological events occu

6. Serum vascular endothelial growth factor as a marker for tubal pregnancy
SUMMARY OBJECTIVE: The objective of this study was to evaluate whether a single measurement of vascular endothelial growth factor could distinguish between intrauterine pregnancy and ectopic pregnancy and to correlate the levels of vascular endothelial growth factor with serum levels of progesterone andβ-human chorionic gonadotropin in each subgroup. METH

9. Out-of-pocket costs for patients with psoriasis in an outpatient dermatology referral service
Abstract Background: Psoriasis is a chronic disease that derives great costs to the health care system. In Colombia, due to deficiencies in this system, patients are more likely to incur in out-of-pocket expenses; money that has never been quantified in this country. Objectives: To quantify out-of-pocket expenses and to analyze their relation to patients'

10. Intra and intersession repeatability and reliability of dynamic parameters in pressure platform assessments on subjects with simulated leg length discrepancy. A cross-sectional research
ABSTRACT BACKGROUND: Leg length discrepancy (LLD) may play a key role in exercise biomechanics. Although the Podoprint platform has been used in dynamic pressure studies, there are no data regarding the reliability and repeatability of dynamic measurements under simulated LLD conditions. OBJECTIVES: To determine the intra and intersession repeatability and
