Restless Legs Syndrome And Neurological Comorbidities: A Narrative Review, Kyrillos Ghattas, Helen Hernandez, Yongwoon Huh, Zhanna Fast, Zhikui Wei

Department of Sleep Medicine Faculty Papers

Restless legs syndrome (RLS) is a common yet underrecognized neurological disorder characterized by uncomfortable sensations and an irresistible urge to move he legs, typically following a circadian pattern. RLS frequently co-occurs with various other neurological diseases, raising questions about shared mechanisms and clinical consequences. This review synthesizes evidence on the prevalence, outcomes, and pathophysiology of RLS in various neurological disorders, including Parkinson's disease, multiple sclerosis, migraine, dementia, stroke, epilepsy, and peripheral neuropathy. In Parkinson's disease, RLS is linked to disease progression and dopaminergic therapy. In stroke and multiple sclerosis, RLS is associated with structural lesions at specific locations, such as …

Do Pressure Requirements Change Over Time With Auto Titrating Positive Airway Pressure Therapy For Obstructive Sleep Apnea?, Anupama Tiwari, Md, Karl Doghramji, Md, Ritu Grewal, Md

Department of Sleep Medicine Faculty Papers

Study Objective:

Prior studies have demonstrated reduced inflammation after chronic use of CPAP therapy. This may lead to reduced pressures over time as the upper airway becomes more compliant. We sought to determine if there was a reduction in 90th percentile pressure requirements in patients on Auto PAP for OSA.

Methods:

A retrospective chart review of 988 patients who underwent a sleep study at our sleep center was performed. Those with moderate to severe sleep apnea who were prescribed and compliant with Respironics Auto PAP were included, yielding a total of 46 patients for analysis. All statistical analysis analyses were …

Does A Short, Thick Neck Predict Obstructive Sleep Apnea?: The Role Of Physical Examination In Osa Screening, Ramya Punati, Md, Shivan Saxena, Md, Constantine Daskalakis, Sc.D., Salvatore Mangione, Md, Ritu G. Grewal, Md

Department of Sleep Medicine Faculty Papers

Purpose:

The purpose of this study was to determine whether a short neck, alone or together with a thick neck, can predict obstructive sleep apnea (OSA).

Methods:

The laryngeal heights of 169 new adult patients presenting to a sleep medicine physician were measured over a period of 5 months. Neck circumference, Mallampati score, and body-mass index (BMI) were also determined, together with medical history, smoking status, and serum bicarbonate. Lastly, patients’ polysomnograms were obtained in order to ascertain the presence or absence of OSA as indicated by the apnea-hypopnea index, as well as other sleep study parameters.

Results:

No association …

Severe Obesity Hypoventilation Syndrome Treated With Auto-Cpap, Zhanna Fast, Md, Ritu G. Grewal, Md

Department of Sleep Medicine Faculty Papers

Summary

Obesity hypoventilation syndrome (OHS) is a serious medical condition that remains undiagnosed in seriously ill hospitalized patients. Significant improvement of daytime hypercapnia can be achieved with positive airway pressure (PAP) therapy. Bi-level PAP is generally employed with the goal of improving ventilation. A 50-year-old woman with OHS and severe hypercapnia was successfully treated with an auto titrating continuous PAP (Auto-CPAP) device. The major role in the pathogenesis of daytime hypercapnia in patients with OHS, is the progressive accumulation of carbon dioxide (CO2) caused by repetitive obstructive events at night, which can be eliminated with the low cost approach of …

Treatment Of Cardiomyopathy With Pap Therapy In A Patient With Severe Obstructive Sleep Apnea., Ritu G. Grewal, Md

Department of Sleep Medicine Faculty Papers

Obstructive sleep apnea is common in patients with heart failure. This case illustrates that treatment with PAP therapy can improve cardiac function in patients with both conditions. CPAP-emergent central apnea, as seen in this patient, has multiple etiologies. It is commonly seen in patients with severe sleep apnea, usually resolves over time, and does not need treatment with adaptive servoventilation.

Obstructive Sleep Apnea Syndrome And Perioperative Complications: A Systematic Review Of The Literature., Tajender S. Vasu, Md, Ms, Ritu G. Grewal, Md, Karl Doghramji, Md

Department of Sleep Medicine Faculty Papers

Obstructive sleep apnea syndrome (OSAS) is a common sleep related breathing disorder. Its prevalence is estimated to be between 2% and 25% in the general population. However, the prevalence of sleep apnea is much higher in patients undergoing elective surgery. Sedation and anesthesia have been shown to increase the upper airway collapsibility and therefore increasing the risk of having postoperative complications in these patients. Furthermore, the majority of patients with sleep apnea are undiagnosed and therefore are at risk during the perioperative period. It is important to identify these patients so that appropriate actions can be taken in a timely …
