The Bethesda System for Reporting Thyroid Cytopathology: A Retrospective Review of its Diagnostic Utility at Johns Hopkins Aramco Healthcare, Saudi Arabia

PURPOSE

Fine needle aspiration (FNA) is the gold standard for assessment of thyroid nodules, with the Bethesda System for Reporting Thyroid Cytopathology (TBSRTC) used to predict the malignancy risk of these nodules. Our aim was to evaluate the diagnostic utility of the TBSRTC for a Saudi population, by comparing the malignancy risk based on histopathology to FNA-based diagnosis of each of the TBSRTC categories and to previously published malignancy risk in other population.

MATERIALS AND METHODS

This was a retrospective study of the data of 241 patients who underwent FNA assessment of thyroid nodules and surgical resection with histopathology at John Hopkins Aramco Healthcare, Dhahran, Saudi Arabia, between January 2016 and December 2019.

RESULTS

The malignancy risk for each of the TBSRTC categories was as follows: non-diagnostic, 25%, benign; 5.74%; atypia of undetermined significance, 37%; suspicious for follicular neoplasm, 38%; suspicious for malignancy, 100%; and malignant, 95%. Our finding were comparable to previously published malignancy risks, except for a higher rate of malignancy in the benign category at 18% compared to 0-3%.

CONCLUSION

Our findings validate the diagnostic reproducibility of the TBSRTC for a Saudi population, with the risk of malignancy confirmed by histopathological assessment being consistent with those previously reported for other populations.

Role of Otolaryngologists in the Treatment of Patients With Riboflavin Transporter Deficiency: A Case Report

Riboflavin transporter deficiency (RTD) is a rare genetic disorder that can have detrimental effects on the nervous system, causing progressive neurodegeneration. Here, we report the second case of RTD in Saudi Arabia. An 18-month-old boy presented to the otolaryngology clinic with six weeks history of progressive noisy breathing associated with drooling, choking, and difficulty in swallowing. Progressive regression of the child's motor and communicative abilities was reported as well. Upon examination, the child had biphasic stridor, chest retractions, bilateral facial palsy, and hypotonia. The presence of an aerodigestive foreign body or congenital anomalies was excluded using bronchoscopy and esophagoscopy. Empirical high-dose riboflavin replacement therapy was initiated upon anticipation of diagnosis. Whole exome sequencing revealed a SLC52A3 gene mutation, which confirmed the diagnosis of RTD. After a period of intensive care unit (ICU) admission with endotracheal intubation, the child's general condition improved, and he was weaned off of respiratory support. Tracheostomy was avoided in this patient, as he responded to riboflavin replacement therapy. During the disease course, an audiological assessment revealed severe bilateral sensorineural hearing loss. He was discharged home on gastrostomy feeding owing to the risk of frequent aspiration, and he was regularly followed up by the swallowing team. The early initiation of high-dose riboflavin replacement appears to be of great value. The benefits of cochlear implants in RTD have been reported, but not fully established. This case report will increase awareness in the otolaryngology community about patients with this rare disease who might initially present to the clinic with an otolaryngology-related complaint.

Association of Pediatric Gastroesophageal Reflux Disease and Subglottic Stenosis: A Systematic Review and Meta-analysis

Gastroesophageal reflux disease in children, which affects approximately 18% of infants, results from gastric contents flowing into the esophagus due to factors such as immature sphincter function. Regurgitation is normal and often resolves by age two; however, persistent gastroesophageal reflux disease can lead to otolaryngological lesions such as subglottic stenosis. PubMed, AIRE, Scholar, MEDLINE, Springer Nature Journal, and Scopus were searched from their inception to February 2024. Pediatric patients < 18 years diagnosed with subglottic stenosis and investigated for gastroesophageal reflux disease or related endoscopic findings were included. Studies not reporting relevant outcomes, duplicates, and non-English studies were excluded. Six studies conducted between 1990 and 2001 explored gastroesophageal reflux-associated otolaryngological issues among pediatrics. Among the 149 participants with subglottic stenosis, 53.47% had laryngopharyngeal reflux disease. Some studies used the Cotton-Myer classification to identify intubation and gastroesophageal reflux disease as primary causes. Younger age and difficulty with intubation were associated with subglottic stenosis severity. Early management of gastroesophageal reflux disease before surgical intervention improved outcomes and reduced endoscopic repair failure rates. A meta-analysis of risk ratios from three studies underscored the relationship's statistical significance, with an overall effect size of 0.03 (95%CI: 0.01 to 0.17) and a P-value < .0001. Heterogeneity analysis showed minimal variability across studies, supporting the observed association between gastroesophageal reflux disease and subglottic stenosis. The prevalence of gastroesophageal reflux disease in pediatric subglottic stenosis cases has been established, stressing the need for early diagnosis and treatment to minimize the necessity of surgery.

Quality of life improvement in children with otitis media with effusion post ventilation tube insertion: A prospective cohort study

OBJECTIVES

To study is to establish the OM-6 scores in Saudi children with OME and subjectively assess the change in QoL following VT insertion. The Otitis Media 6 (OM-6) questionnaire is a widely used measure of the quality of life (QoL) in children with otitis media with effusion (OME). Myringotomy with ventilation tube (VT) insertion is indicated when OME persists with clinically documented hearing impairment.

METHODS

The present study is a prospective cohort study investigating the QoL of children with OME using a validated OM-6 questionnaire. The caregivers of 100 children were subjected to the questionnaire preoperatively from January 2023 to December 2023. All included patients underwent bilateral myringotomy and VT insertion with adenoidectomy under general anaesthesia. Caregivers were asked to complete the OM-6 questionnaire three months postoperatively to assess the change in QoL.

RESULTS

A total of 100 children were enrolled in this study. The average OM-6 score was 16 before surgery and reduced to 7 after surgery. There is a statistically significant reduction in the score after the surgery (p<0.001). While considering the OM-6 score separately, the Wilcoxon signed rank test shows that, there is statistically significant reduction in the average score of all the variables except caregiver concern, which remained the same pre and post-surgery (p<0.001).

CONCLUSION

The QoL of children with OME measured by OM-6 questionnaire significantly improved following VT insertion.

National survey on Congenital Cytomegalovirus Awareness and Screening Practices among Healthcare Professionals

OBJECTIVES

Congenital cytomegalovirus (CMV) infection, resulting from maternal-fetal transmission of CMV, poses a substantial risk to maternal and child health. It is the most prevalent congenital viral infection, and the prevention and management of this condition rely heavily on the knowledge and awareness of healthcare professionals.

METHODS

This cross-sectional survey was conducted between March 1, 2023, and August 31, 2023, across multiple tertiary centers in various Saudi Arabian cities. It assessed the understanding and awareness of congenital CMV infection among 400 healthcare professionals from diverse specialties. The study utilized a structured questionnaire to evaluate knowledge levels, obtain demographic data, and identify factors influencing awareness.

RESULTS

The study revealed significant disparities in knowledge levels, with around 84 % of participants categorized as having "low" knowledge. Obstetricians and gynecologists exhibited better knowledge. Factors like specialization, age, and professional experience significantly affected knowledge levels. Additionally, many healthcare professionals perceived a lack of information and awareness regarding CMV among their peers.

CONCLUSION

Congenital CMV infection is a major public health concern with potential severe consequences. The study identified knowledge disparities, particularly among non-specialist healthcare practitioners, emphasizing the need for targeted educational programs and focused awareness initiatives. Key factors, such as expertise, age, and experience, underscore the importance of addressing ongoing knowledge gaps, highlighting the need for continuous efforts to mitigate challenges associated with CMV infection.
