Current guidelines recommend adding long-acting muscarinic antagonists (LAMAs) in patients with uncontrolled asthma, despite the use of moderate to high doses of inhaled steroid-long-acting beta agonists (ICS/LABA). This study aims to analyze the factors related to the prescription of add-on LAMA in clinical practice for asthma patients, shedding light on physicians' preferences. This study included adult asthma patients on add-on LAMA and ICS/LABA monitored for at least one year in a national registry comprising 2053 asthmatics.

Hamamy Syndrome is an autosomal recessive syndrome with craniofacial, neurological, and osteological implications. Patients most commonly present with repeated long fractures however, other affected systems with their respective clinical presentations warrant a thorough reporting and understanding of this genetic disorder. Herein, the authors, present a 21-year-old male patient diagnosed with Hamamy Syndrome with bilateral stenosis of the optic canals and associated bilateral vision loss.

Article Synopsis
  • A global collaborative study reviewed the management and outcomes of malignant skull base tumors, collecting data from 28 institutions involving 3,061 patients.
  • The majority of surgeries utilized an open approach (55%), with endoscopic (36%) and combined techniques (9.6%) being less common, and the overall 5-year survival rates were 65% for overall survival (OS) and 71.7% for disease-specific survival (DSS).
  • Factors such as older age, comorbidities, and the extent of tumor involvement were identified as independent predictors of survival, while adjuvant radiation therapy (RT) emerged as a protective factor in outcomes.

Article Synopsis
  • NSAID-exacerbated respiratory disease (NERD) leads to worsened respiratory symptoms after taking NSAIDs, and new treatments like biologicals are being explored alongside traditional aspirin desensitization (ATAD).
  • This study compared the quality of life and respiratory health outcomes between NERD patients treated with ATAD and those treated with biologicals, specifically mepolizumab and omalizumab.
  • Results showed that mepolizumab significantly reduced blood eosinophil counts and the need for sinus surgeries compared to ATAD, but no major differences were found in other clinical parameters between the two treatment groups.

Purpose: Expansion sphincter pharyngoplasty (ESP) is a common surgery for patients with obstructive sleep apnea (OSA) which aims to correct the obstruction at the palatal level. The effectiveness of ESP has been widely shown in the literature using surgical success rates, but to our knowledge, there is no research which documents the changes in the upper airway anatomy objectively. We aimed to demonstrate the effectiveness of expansion sphincter pharyngoplasty using acoustic pharyngometry.
