Noise-Induced Hearing Loss and Use of Hearing Protection Awareness among Medical Students in Saudi Arabia: Mixed Qualitative and Quantitative Study.

BACKGROUND: Noise-Induced Hearing Loss (NIHL) is a prevalent occupational hazard among healthcare professionals, including medical students. Despite its detrimental effects, the awareness and utilization of hearing protection measures among medical students in Saudi Arabia remain understudied. OBJECTIVE: Is to determine the level of awareness and understanding of NIHL among medical students in Saudi Arabia, as well as their knowledge and usage of hearing protection measures and to identify potential barriers and facilitators for hearing protection utilization. METHODS: A mixed-methods approach was employed, involving a questionnaire survey and semi-structured interviews. The survey collected data on demographics, knowledge of NIHL, and hearing protection practices among medical students. Subsequently, a semi-structured interview was conducted to obtain in-depth insights into the students' experiences, attitudes, and beliefs regarding NIHL and the use of hearing protection. RESULTS: The level about NIHL was 59.32%. Better access to information is associated with increased odds of awareness (odds ratio=3.07, p=0.012). Having relatives with hearing loss increases the odds of awareness (odds ratio =2.49, p=0.034). Individuals with hearing loss or impairment have higher odds of awareness (odds ratio =2.27, p=0.046). Ear Pain, temporary hearing loss, tinnitus, or ringing in the ear: These factors are not significantly associated with awareness of noise-induced hearing loss (p>0.05). Using hearing aids is strongly associated with increased odds of awareness (odds ratio =3.94, p=0.006).The quantitative analysis provided statistical information on the prevalence rates and factors influencing hearing protection usage, while the qualitative analysis uncover nuanced perspectives and experiences. CONCLUSION: This research will contribute to the understanding of NIHL and hearing protection practices among medical students in Saudi Arabia. Improving hearing protection awareness and practices among medical students can ultimately reduce the incidence of NIHL and promote a healthier work environment within the healthcare sector.

Partial Obstruction of the Endotracheal Tube by a Part of the Metallic Stylet; Case Report and Review of the Literature.

Endotracheal intubation is common in the emergency department, intensive care units, and operating rooms. It involves the insertion of an endotracheal tube (ETT) through the mouth or nose into the trachea to maintain a patent airway and facilitate mechanical ventilation. Using a stylet during intubation can guide the ETT through the vocal cords. However, complications can arise when the stylet is not removed after successful intubation. Herewith, we reported a patient who was two years old and suffered from respiratory failure. However, in the first 12 hours, we observed a foreign body in the trachea, a small end of a metal stylet immediately removed by bronchoscope. This case demonstrates that multiple uses of a stylet, especially by a single user, can result in impaction of the stylet in the ETT during intubation, requiring force when the stylet is withdrawn after intubation, which can result in breakage, shearing, and retention of the stylet or plastic sheath in the lumen of the ETT.

Patterns and Correlations of Hearing Loss Among Adolescents, Adults, and Elderly in Saudi Arabia: A Retrospective Study.

Background According to the World Health Organization (WHO), hearing loss (HL) has a significant disease burden with a global prevalence as high a 5% with an expected exponential rise in the coming years. HL has medical, social, and psychological implications on one's health. A significant proportion of HL cases might be the result of preventable conditions, especially among the young.  Aim To estimate the pattern of HL and its correlates among adolescent, adult, and elderly populations in the southern regions of Saudi Arabia. Methodology A retrospective observational study was carried out between May 2018 and April 2019 across four different ENT clinics located across Saudi Arabia. We included all patients who had a clinical diagnosis of conductive, sensorineural, or mixed HL with varying degrees of severity tested via Pure Tone Audiometer (PTA). Results We included 332 cases with HL, ages ranged from 14 to 62 years old with a mean age of 45.2 ±12.6 years. HL was bilateral in 72% of the cases and was associated with tinnitus in 43.1% of cases. Sensorineural HL was the predominant pattern of HL among the elderly and conductive pattern was more common among the young. Causes such as infections, congenital causes, and age-related damage were among the key causes of HL.  Conclusion Our study showed that HL might be more prevalent among the Saudi population than previously reported. Sensorineural HL is most common among the elderly. However, conductive HL following ear infections is the main cause of HL among young. Therefore, there is a need for significant improvement in public health surrounding ear health to prevent reversible causes of HL, especially among the young.

Catgut Versus Polypropylene Sutures for Transcolumellar Incision Closure in Open Rhinoplasty: A Retrospective Cohort Study.

Background Open rhinoplasty, including the transcolumellar approach, is commonly performed as it has fewer side effects and provides superior anatomical control to the surgeons compared to closed rhinoplasty. However, the postoperative scar outcomes, such as scar appearance, vary depending on the type of suture used in wound closure, and the optimal suture type is not firmly established. Objective To compare the impact of catgut versus polypropylene sutures on the postoperative transcolumellar scar outcomes and patient satisfaction following open rhinoplasty. Methods This retrospective cohort study, including 100 patients who underwent transcolumellar open rhinoplasty, was conducted at otolaryngology department of King Abdulaziz University Hospital, Riyadh, KSA. The patients were divided into two groups: the propylene suture group (group 1), which included 15 males and 35 females with a mean age of 31.5 years and underwent surgery using propylene sutures, and the catgut suture group (group 2), which included 10 males and 40 females with a mean age of 30.5 years and underwent surgery using catgut sutures. The postoperative transcolumellar scar outcomes, as determined by visual analogue scale (VAS) and Stony Brook Scar Evaluation Scale (SBSES) scores, and patient satisfaction, as assessed using a self-assessment scale, were compared between groups. Results The scars were unnoticeable in the majority of both groups: 88% in group 1 and 86% in group 2. The VAS and SBSES scores did not significantly differ between groups. Patients' satisfaction rates were also comparable and did not significantly differ between groups (p = 0.341). Conclusion Both catgut and polypropylene sutures lead to similar outcomes and patient satisfaction rates in terms of postoperative rhinoplasty transcolumellar scars. Thus, catgut may be the optimal suture for closing transcolumellar incisions following open rhinoplasty.
