RESUMO
OBJECTIVE: To assess barium esophagram (BAS) as a diagnostic marker for patients with Killian Jamieson diverticula (KJD). METHODS: Prospective, multicenter cohort study of individuals enrolled in the Prospective OUtcomes of Cricopharyngeus Hypertonicity (POUCH) Collaborative. Patient demographics, comorbidities, radiographic imaging reports, laryngoscopy findings, patient-reported outcome measures (PROM), and operative reporting were abstracted from a REDCap database and summarized using means, medians, percentages, frequencies. Paired t-tests and Wilcoxon Signed Rank test were used to test pre- to post-operative differences in RSI, EAT-10, and VHI-10 scores. Diagnostic test evaluation including sensitivity, specificity, positive, and negative predictive value with 95% confidence intervals were calculated comparing BAS findings to operative report. RESULTS: A total of 287 persons were enrolled; 13 (4%) patients were identified with confirmed KJD on operative reports. 100% underwent open transcervical excision. BAS has a 46.2% (95% confidence interval [CI]: 23.2, 70.9) sensitivity and 97.8% (95% CI: 95.3, 99.0) specificity in detecting a KJD and 50% (95% CI: 25.4, 74.6) positive predictive value but 97.4% (95%CI: 94.8, 98.7) negative predictive value. Preoperatively, patients reported mean (SD) RSI and EAT-10 of 19.4 (9) and 8.3 (7.5) accordingly. Postoperatively, patients reported mean (SD) RSI and EAT-10 as 5.4 (6.2) and 2.3 (3.3). Both changes in RSI and EAT-10 were statistically significant (p = 0.008, p = 0.03). CONCLUSION: KJD are rare and represent <5% of hypopharyngeal diverticula undergoing surgical intervention. Open transcervical surgery significantly improves symptoms of dysphagia. BAS has high specificity but low sensitivity in detecting KJD. LEVEL OF EVIDENCE: 4 Laryngoscope, 133:2110-2115, 2023.

OBJECTIVE: Tracheal reconstruction using a stem cell-based engineered trachea has recently shown promise. Our goal is to achieve a single-stage stem cell-based tracheal replacement. STUDY DESIGN: Prospective feasibility study. SETTING: Wake Forest Institute of Regenerative Medicine. SUBJECTS AND METHODS: Five healthy male beagles were implanted with a 2.5-cm segment of decellularized trachea. A sixth animal, planned for the control arm, died of anesthetic complications prior to tracheal implantation. The remaining 5 beagles were divided into 2 study arms: 4 had adipose-derived stem cells coating the lumen of the donor trachea, and a control animal had the trachea implanted cell free. The donor tracheas were obtained from previously sacrificed size-matched canines and decellularized. The adipose tissue was harvested from a recipient animal and the trachea prepared, seeded, and then implanted, all in one operation. Adipose stem cells were labeled fluorescently. RESULTS: Five of 6 planned surgical procedures were completed successfully. All required sacrifice for airway distress at approximately 1 week postoperatively. All tracheal grafts were found to be malacic and compromised. CONCLUSION: In a canine model using a decellularized tracheal scaffold and adipose stem cells, the postoperative inflammatory response and evidence of rejection was minimal. However, all scaffolds exhibited breakdown, compromising the animals' airways, necessitating euthanasia earlier than planned. For future study, a similar animal model using a single-stage approach with a more robust scaffold may allow for greater survival and stem cell differentiation.

We report a case of a 39-year-old female with a recent diagnosis of dermatomyositis and dysphonia. Dermatomyositis is a connective tissue disease with multisystem involvement: cardiac, pulmonary, musculoskeletal, gastrointestinal, and dermatologic are the most common. While dermatomyositis affects thousands of individuals in the United States, laryngeal involvement has only been described in a single case report to date.

OBJECTIVE: Proton pump inhibitors (PPIs) are the mainstay of current medical management for laryngopharyngeal reflux, and treatment often involves long-term use of this class of medications. The long-term adverse effects of PPI use have not been studied extensively, but several analyses have demonstrated epidemiological links between PPI use and adverse outcomes. These include altered mineral and vitamin absorption, orthopedic injury, acute coronary syndromes (ACS), and infectious risks. STUDY DESIGN: A PubMed search was performed for subject headings, including PPIs and adverse outcomes. Relevant studies were included in this review. Studies were compiled, reviewed, and compared in a narrative form. RESULTS: Several epidemiological links between PPI use and metabolic, infectious, cardiac, and orthopedic adverse outcomes were found. No definite causal effects were identified. CONCLUSION: Given these epidemiological patterns, we recommend that the clinician be aware of these possible unintended consequences. In addition, we recommend consideration of dual-energy X-ray absorptiometry (DEXA) bone density scans in at-risk patients who have not been previously tested. We recommend consideration of vitamin B12 and iron levels in selected patients who are at high risk. We also recommend close communication with our cardiology colleagues, as we attempt to ascertain the relationship between clopidogrel and PPI use. We recommend caution in the use of omeprazole in patients undergoing active treatment for ACS. Finally, we recommend consideration of Helicobacter pylori or serum gastrin level testing in patients with known risk factors for gastric carcinoma.

Vocal ford paralysis is a condition often seen in otolaryngologic adult and pediatric clinics. We report a case we believe to be the youngest child to undergo ansa cervicalis (ansa) to recurrent laryngeal nerve (RLN) reinnervation for unilateral vocal fold paralysis. We have included the preoperative and postoperative videostroboscopic and acoustic findings. The acoustic data shows improvement and is consistent with the patient's improved voice quality. Most notably the patient's voice quality is less raspy and his volume has improved while subjectively requiring less effort.

Metastatic calcification (MC) commonly results secondary to phosphorus and calcium dysregulation in end-stage renal disease (ESRD). Only once before has MC been reported to involve a true vocal cord. A 35-year-old man with ESRD and secondary hyperparathyroidism was evaluated for hoarseness. Three years ago, he underwent a total parathyroidectomy with parathyroid autograft to the forearm. Simultaneously, he had a left lobe thyroidectomy that displayed a papillary thyroid carcinoma. Since that time, he continued to have hyperphosphatemia and hypocalcemia. Laryngoscopy displayed a small papillomatous lesion on the right true vocal cord. He underwent excision of the vocal cord lesion; histologic examination demonstrated benign squamous epithelium with extensive submucosal calcification. In patients with ESRD with secondary dysregulation of serum phosphorus to calcium level balance, MC may involve variable anatomical locations, including the true vocal cords. Regarding histologic findings, pathologists must consider malignancies associated with calcification, mimicking a benign process.

BACKGROUND: Unsedated office-based laser surgery (UOLS) of the larynx and trachea has significantly improved the treatment options for patients with laryngotracheal pathology including recurrent respiratory papillomas, granulomas, leukoplakia, and polypoid degeneration. UOLS delivered by flexible endoscopes has dramatically impacted office-based surgery by reducing the time, costs, and morbidity of surgery. OBJECTIVES: To review our experience with 443 laryngotracheal cases treated by UOLS. METHODS: The laser logbooks at the Center for Voice and Swallowing Disorders were reviewed for UOLS, and the medical and laryngological histories were detailed, as were the treatment modalities, frequencies, and complications. RESULTS: Of the 443 cases, 406 were performed with the pulsed-dye laser, 10 with the carbon-dioxide laser, and 27 with the thulium: yttrium-aluminum-garnet laser. There were no significant complications in this series. A review of indications and wavelength selection criteria is presented. CONCLUSION: Unsedated, office-based, upper aerodigestive tract laser surgery appears to be a safe and effective treatment option for many patients with laryngotracheal pathology.
