The association between obstructive sleep apnea and osteoporosis: A systematic review and meta-analysis.

Obstructive sleep apnea (OSA) is a sleep disorder with well-known metabolic consequences. The relationship between OSA and bone health, especially osteoporosis, remains poorly understood. Given that both OSA and osteoporosis are highly prevalent chronic conditions with significant public health implications, this study aims to investigate the association of OSA with bone health and osteoporosis.

Mandibular Advancement vs CPAP for Blood Pressure Reduction in Patients With Obstructive Sleep Apnea.

Background: Hypertension guidelines recommend diagnosis and treatment of obstructive sleep apnea (OSA) in patients with hypertension. The mandibular advancement device (MAD) is an oral appliance therapy for patients who decline or cannot tolerate continuous positive airway pressure (CPAP).

Objectives: We compared the relative effectiveness of MAD vs CPAP in reducing 24-hour ambulatory blood pressure (BP).

The Association Between Transverse Maxillary Deficiency and Septal Deviation in Adults with Obstructive Sleep Apnea.

Objectives: Recent evidence suggests that environmental factors impact craniofacial development. Specifically, the height and width of the maxilla may impact the degree of septal deviation. We sought to determine the relationship between transverse maxillary deficiency and severity of septal deviation.

Posterior Palatal Expansion via Subnasal Endoscopy (2PENN) for Maxillary Deficiency: A Pilot Study.

Objective: Surgically assisted rapid palatal expansion (SARPE) addresses transverse maxillary deficiency, a known contributor to nasal obstruction. The purpose of this study was to assess the feasibility, preliminary outcomes, and safety of posterior palatal expansion via subnasal endoscopy (2PENN), a modified SARPE procedure, aimed at achieving anterior and posterior maxillary expansion.

Methods: This prospective case series included consecutive adult patients with findings of transverse maxillary deficiency that underwent the 2PENN procedure from 4/2021 to 4/2022.

Mandibular advancement device versus CPAP in lowering 24-hour blood pressure in patients with obstructive sleep apnoea and hypertension: the CRESCENT trial protocol.

Introduction: Although treatment of obstructive sleep apnoea (OSA) using continuous positive airway pressure (CPAP) reduces blood pressure (BP), adherence to CPAP is often suboptimal. A mandibular advancement device (MAD) is a guideline-endorsed alternative therapy for OSA. Still, there is limited evidence on the relative efficacy between MAD and CPAP on BP reduction.

Enhanced drug-induced sleep endoscopy: Distinguishing central from obstructive apnea.

This case report describes a patient originally diagnosed with obstructive sleep apnea (OSA) who was later found to have central sleep apnea (CSA) during drug-induced sleep endoscopy, which was subsequently confirmed on an in-laboratory sleep study. The revised diagnosis resulted in a change in recommended therapy from hypoglossal nerve stimulation to phrenic nerve stimulation. This case report is a reminder that the sleep surgeon must be cognizant of the possibility of CSA being misclassified as OSA especially as home sleep studies become increasingly routine, and discusses ways to more easily distinguish between CSA and OSA.

International Consensus Statement on Obstructive Sleep Apnea.

Background: Evaluation and interpretation of the literature on obstructive sleep apnea (OSA) allows for consolidation and determination of the key factors important for clinical management of the adult OSA patient. Toward this goal, an international collaborative of multidisciplinary experts in sleep apnea evaluation and treatment have produced the International Consensus statement on Obstructive Sleep Apnea (ICS:OSA).

Methods: Using previously defined methodology, focal topics in OSA were assigned as literature review (LR), evidence-based review (EBR), or evidence-based review with recommendations (EBR-R) formats.

Obstructive sleep apnea during acute coronary syndrome is related to myocardial necrosis and wall stress.

Background: The relative contribution of pathophysiological mechanisms in acute coronary syndrome (ACS) towards obstructive sleep apnea (OSA) is not well-studied. We examined the correlation between severity of OSA and inflammation, myocardial necrosis, wall stress, and fibrosis.

Methods: A total of 89 patients admitted with ACS underwent a sleep study during index admission.

The Emerging Role of Drug-Induced Sleep Endoscopy in the Management of Obstructive Sleep Apnea.

Obstructive sleep apnea is a prevalent sleep disorder characterized by partial or complete obstruction of the upper airway. Continuous positive airway pressure is the first-line therapy for most patients, but adherence is often poor. Alternative treatment options such as mandibular advancement devices, positional therapy, and surgical interventions including upper airway stimulation target different levels and patterns of obstruction with varying degrees of success.

Sleep Apnea and Heart.

Scientific investigations in the past few decades have supported the important role of sleep in various domains of health. Sleep apnea is a highly prevalent yet underdiagnosed sleep disorder representing a valid cardiovascular risk factor, particularly for hypertension. While several studies have demonstrated the benefits of sleep apnea treatment on subclinical cardiovascular measures, there is a paucity of studies proving reduction of cardiovascular events and mortality.

Rare Cause of Facial Palsy: Case Report of Tick Paralysis by Ixodes Holocyclus Imported by a Patient Travelling into Singapore from Australia.

Background: Ticks are blood-sucking arachnids that feed on all classes of vertebrates, including humans. Ixodes holocyclus, also known as the Australian Paralysis Tick, is capable of causing a myriad of clinical issues in humans and companion animals, including the transmission of infectious agents, toxin-mediated paralysis, allergic and inflammatory reactions, and mammalian meat allergies in humans. The Australian Paralysis Tick is endemic to Australia, and only two other exported cases have been reported in the literature.

Intratympanic steroids as a salvage treatment for sudden sensorineural hearing loss? A meta-analysis.

Sudden sensorineural hearing loss is typically treated with systemic steroids. The aim of this meta-analysis was to evaluate the efficacy of salvage intratympanic steroid treatment in patients who have initial treatment failure with systemic steroids. A MEDLINE literature search was performed, supported by searches of Web of Science, Biosis, and Science Direct.

Clinical audit of the microbiology of otorrhoea referred to a tertiary hospital in Singapore.

Introduction: Otorrhoea is a common complaint in Ear, Nose and Throat clinics. This study aimed to establish the pathogens involved in cases of otorrhoea in Singapore, their sensitivity patterns and the effectiveness of empirical management.

Methods: A retrospective chart review was conducted on 91 patients with otorrhoea who had undergone swab cultures between July 2010 and February 2011.

Low local recurrence rates in young Asian patients with phyllodes tumours: less is more.

Background: Phyllodes tumours are increasingly being discovered incidentally in young patients after excision of a seemingly innocuous breast lump. The clinical course of this group of patients has not been well-described, especially in the Asian population.

Methods: A retrospective review of 44 consecutive patients below 25 years of age undergoing surgery for phyllodes tumours at our institution from 1992 to 2010 was conducted.
