Successful Avoidance of Cicatricial Tracheobronchial Stenosis in a Patient With Endobronchial Tuberculosis by Early Administration of Systemic High-Dose Corticosteroids: A Case Report.
A 63-year-old Japanese woman was referred to our hospital due to dry cough, fever, hoarseness, stridor, and difficulty breathing. Chest computed tomography showed circumferential wall thickening in the trachea, carina, right main bronchus, and right upper lobe bronchus, and granular and nodular shadows in right S. Flexible laryngofiberscopy showed yellowish dry respiratory secretions adhering to the subglottis. Bronchoscopic findings showed that the tracheobronchial mucosa was swollen, hyperemic, and covered with yellowish-white, cheese-like materials, and ulcerative lesions with white coatings were observed from the subglottis to the trachea, carina, right main bronchus, and right upper lobe bronchus. A diagnosis of endobronchial tuberculosis (EBTB) was confirmed by polymerase chain reaction testing, and cultures were positive for . In addition to anti-tuberculosis chemotherapy, intravenous high-dose methylprednisolone reduced her severe respiratory symptoms and prevented cicatricial tracheobronchial stenosis. Early administration of systemic high-dose corticosteroids may be effective for EBTB patients with severely active tracheobronchial mucosal and submucosal lesions.

Subglottic stenosis (SGS) can be asymptomatic in cases with slow-growing granulomas. In this study, we report a case of SGS discovered during tracheal intubation for anesthesia induction. A 74-year-old woman was scheduled for surgery under general anesthesia for a left humeral fracture. Resistance was observed when the tracheal tube passed through the glottis, stopping the tube from advancing. We placed a laryngeal mask (LMA) to secure her airway and examined it using a bronchial fiber to detect circumferential stenosis of the subglottis due to granulation. The airway was secured using an LMA instead of intubation, and the patient was successfully managed under anesthesia. Asymptomatic SGS is difficult to detect preoperatively, and anesthesiologists may encounter unexpected intubation issues. LMA is an important tool for an effective strategy to manage intubation difficulties.

The risk of endotracheal tube (ETT) placement includes endobronchial intubation and subglottic injury. This study aimed to describe the lengths of lower airway parameters related to cuff location and vocal cord markings in different adult-sized ETTs. Eighty cadavers were examined for the lengths of the lower airway, including their correlations and linear regressions with height. Thirty adult-sized ETTs from seven different brands were examined for Mark-Cuff and Mark-Tip distances. The depth of ETT placement was simulated for each brand using vocal cord marking. The mean (standard deviation) lengths from the subglottis, trachea, vocal cord to mid- trachea, and vocal cord to carina were 24.2 (3.5), 97.9 (8.6), 73.2 (5.3), and 122.1 (9.0) mm, respectively. Airway lengths were estimated as: (1) subglottis (mm) = 0.173 * (height in cm) - 3.547; (2) vocal cord to mid-trachea (mm) = 0.28 * (height in cm) + 28.391. There were variations in the Mark-Cuff and Mark-Tip distances among different ETTs. In the simulation, endobronchial intubation ranged between 2.5 and 5% and the cuff in the subglottis ranged between 2.5 and 97.5%. In summary, the lower airway parameters were height-related. ETT placement using vocal cord marking puts the patient at a high risk of cuff placement in the subglottis.

Shabbir Syndrome or commonly known as Laryngo-onycho-cutaneous syndrome (LOCS) is an autosomal recessively inherited syndrome, caused due to mutations in the laminin alpha-3 (LAMA3) gene. This syndrome affects the epidermal layer and results in granulation formation in the eyes, larynx, and nails. One of the most dreadful complications of this syndrome can be due to granulation formation in the larynx or sub-glottis region resulting in laryngeal stenosis and death. According to the latest (OMIM) classification, LOCS has been reclassified as a subtype of Junctional epidermolysis bullosa (JEB). But it is still considered a rare syndrome with limited cases reported worldwide. In this case report, we have discussed a case of a four year old, Pakistani boy, who presented with stridor, fragile skin, and granulation of nails, with no family history of LOCS.

Dysphagia is common in idiopathic Parkinson's disease (IPD) and is associated with impairments in both swallowing safety and swallowing efficiency. The goals of this study were to define post-swallow residue patterns in people with IPD and describe pathophysiological endoscopic findings affecting residue accumulation. This was a prospective single-blinded cross-sectional cohort study of patients with the diagnosis of IPD recruited from a Movement Disorder Clinic. Clinical variables included patient age, cognitive function, and measures of disease severity, and laryngoscopic examinations with a flexible endoscopic evaluation of swallowing (FEES) were completed for each patient. Visual Analysis of Swallowing Efficiency and Safety (VASES) was used to analyze FEES. Post-swallow residue outcomes and non-residue endoscopic outcomes including the Bowing index, Penetration Aspiration Scale (PAS) score, premature leakage, and build-up phenomenon were evaluated. Multiple regression models were used to evaluate factors affecting the residue at different anatomic levels. Overall 53 patients completed the study. The multiple regression analyses showed a relation between (1) the presence of residue at the level of oropharynx and epiglottis with premature leakage, (2) the presence of residue at the level of the laryngeal vestibule and vocal folds with build-up phenomenon, and (3) the presence of residue at the level of the hypopharynx, laryngeal vestibule, and subglottis with airway invasion. Residue pattern during FEES is associated with specific swallow dysfunctions in IPD. Using residue localization and quantification may be a helpful tool in assessing the impact of targeted swallowing interventions in patients with IPD and dysphagia.
