Differences in Survival between Black and White Patients with Head and Neck Squamous Cell Carcinoma: Comparison of Data from the DOD Central Cancer Registry and SEER

BACKGROUND

Barriers to health care access may contribute to the poorer survival of Black patients with head and neck squamous cell carcinoma (HNSCC) than their White counterparts in the U.S. general population. The Department of Defense's (DOD) Military Health System (MHS) provides universal health care access to all beneficiaries with various racial backgrounds.

METHODS

We compared overall survival of patients with HNSCC by race in the MHS and the general population, respectively, to assess whether there were differences in racial disparity between the two populations. The MHS patients were identified from the DOD's Central Cancer Registry (CCR) and the patients from the U.S. general population were identified from the NCI's Surveillance, Epidemiology and End Results (SEER) program. For each cohort, a retrospective study was conducted comparing survival by race.

RESULTS

Black and White patients in the CCR cohort had similar survival in multivariable Cox regression models with a HR of 1.04 and 95% confidence interval (95% CI) of 0.81 to 1.33 after adjustment for the potential confounders. In contrast, Black patients in the SEER cohort exhibited significantly worse survival than White patients with an adjusted HR of 1.47 (95% CI = 1.43-1.51). These results remained similar in the subgroup analyses for oropharyngeal and non-oropharyngeal sites, respectively.

CONCLUSIONS

There was no racial difference in survival among patients with HNSCC in the MHS system, while Black patients had significantly poorer survival than White patients in the general population.

IMPACT

Equal access to health care could reduce racial disparity in overall survival among patients with HNSCC.

Anterior Cervical Pain Syndromes: Defining the Patient Population and Approach to Treatments

Objective This study aimed to evaluate patients with anterior cervical pain syndromes (ACPSs) by describing patient characteristics, therapeutic interventions, and response to treatments. Study Design This is a retrospective observational study. Methods Patients treated for diagnoses associated with ACPSs over a seven-year period in one laryngology practice at a tertiary care center were identified and evaluated via a review of clinical and surgical records. Patients identified to have undergone any treatment for ACPSs via medication, trigger-point injections of local anesthetics mixed with steroids, and/or surgical resection of the greater cornu of the hyoid bone and superior cornu of the thyroid cartilage were included. Participants subsequently underwent a medical record review and telephone interview to determine response to treatments. Results Twenty-seven patients met the inclusion criteria, including 12 patients (44.4%) with superior laryngeal neuralgia (SLN), seven patients (25.9%) with superior thyroid cornu syndrome (STCS), and eight patients (29.6%) with hyoid bone syndrome (HBS)/clicking larynx syndrome. The most common symptoms were neck/throat pain (27, 100%), globus sensation (20, 74.1%), and dysphagia (20, 74.1%). A total of 24 patients (93.3%) underwent point injections of bupivacaine and dexamethasone. Of these, 12 patients (52.2%) demonstrated a complete response that was permanent in six patients (26.1%). Seven patients (25.9%) underwent surgical intervention, with at least partial improvement noted in six patients (85.7%). Conclusion ACPSs constitute a number of complex diagnoses that remain poorly characterized in the literature. The use of point injections of local anesthetics with steroids appears efficacious with surgical options available for those with an incomplete response or return of symptoms.

Treatment of Relapsing HPV Diseases by Restored Function of Natural Killer Cells

Human papillomavirus (HPV) infections underlie a wide spectrum of both benign and malignant epithelial diseases. In this report, we describe the case of a young man who had encephalitis caused by herpes simplex virus during adolescence and currently presented with multiple recurrent skin and mucosal lesions caused by HPV. The patient was found to have a pathogenic germline mutation in the X-linked interleukin-2 receptor subunit gamma gene (IL2RG), which was somatically reverted in T cells but not in natural killer (NK) cells. Allogeneic hematopoietic-cell transplantation led to restoration of NK cytotoxicity, with normalization of the skin microbiome and persistent remission of all HPV-related diseases. NK cytotoxicity appears to play a role in containing HPV colonization and the ensuing HPV-related hyperplastic or dysplastic lesions.

Low-Dose Prednisone Therapy is Efficacious in Treating Painful Subacute Thyroiditis

Subacute thyroiditis (SAT) usually presents with neck pain, radiating to ears and is often associated with hyperthyroidism. Currently the available treatment involves administration of NSAID or in more symptomatic patients prednisone 40mg daily tapered over 6 weeks or longer. We report successful treatment of 3 patients (Pts) with SAT with low-dose prednisone therapy (20mg/day) (LDP20) initially and tapered over 4 weeks. Patient 1: A 32-year-old female presented with severe neck pain radiating to both ears and low- grade fever of 2-weeks duration. Two weeks prior, patient had cold-like symptoms lasting for 3 days. Physical examination: HR 110bpm, tremors of fingers noted, tenderness of the anterior neck present, thyroid 30-gms in size. Labs: ESR 92 mm/hr, CRP 3.2 mg/dL, TSH <0.005 uIU/mL, free T4 2.71 ng/dL, total T3 168 ng/mL. Thyroid scan and uptake showed a 24-hrs uptake <1%, thyroid gland not visualized, consistent with SAT. Patient was treated with atenolol and LDP20 tapered over 4 weeks. Pain significantly improved after 2 days of treatment. Six weeks later TSH was 0.9 uIU/mL with a free T4 1.4 ng/dL and ESR 8 mm/hr. Patient 2: A 19-year-old female presented with left-ear pain, anterior neck pain, fever, and extreme fatigue. PE: HR 111bpm, heat shield present, tender-to-palpation thyroid, brisk DTR. Lab: CBC normal, ESR 98 mm/hr, CRP 9.9 mg/dL, TSH <0.01 uIU/mL, free T4 3.8 ng/dL, total T3 210 ng/mL. Thyroid scan and uptake: uptake <1%, no thyroid gland visualized and SAT was diagnosed. Patient was started on LDP20 and atenolol. Four days following prednisone therapy her symptoms completely resolved and prednisone was tapered off over 4 weeks. Thyroid functions were normal by the seventh week. Patient 3: A 38-year-old male presented with fever, fatigue, severe neck pain, palpitation and a weight loss of 8 pounds. PE: HR 120 bpm, thyroid severely tender on palpation, brisk DTR. Lab: normal CBC, ESR 128 mm/hr, CRP 11.9 mg/dL, TSH <0.001 uIU/mL, free T4 4.2 ng/dL, total T3 201 ng/mL. Thyroid scan: thyroid gland not visualized and uptake was < 1%. SAT was diagnosed and patient was treated with propranolol and LDP20. After 5 days the dose of prednisone was reduced to 15mg/day and the prednisone was tapered over five weeks. Patient had resolution of symptoms in 70 hours and remained asymptomatic for the next 12 months of follow-up. Thyroid function normalized by the eighth week. Conclusion: SAT is a painful disabling thyroid disorder apparently caused by a viral infection; and NSAID or high-dose steroid treatment remains the standard of care. We have treated 3 Pts with relatively lower doses of prednisone than previously recommended and attained remission successfully. Thus side effects can be avoided with lower prednisone dose.

A new lateral neck mass in a 63-year-old man with multinodular goiter

Described is a rare presentation of ectopic thyroid tissue as a lateral neck mass. This case raises the awareness that a lateral neck mass (including ectopic thyroid mass) needs appropriate investigations to rule out malignancy.

Left Paraglossal Approach for Airway Management of Patient With Large Neck Mass in an Austere Environment: A Case Report

We present the case of a 25-year-old man with a significant neck mass and describe the technique used for managing his airway given limited equipment in an austere environment. Physical examination and imaging revealed significant proximal airway involvement. Without access to a fiberoptic bronchoscope, we sought a technique that might avoid contact with the mass from both the laryngoscope and endotracheal tube. In this case report, we describe our approach to left paraglossal laryngoscopy and intubation under general anesthesia-a method not well described in the literature and proved to be imperative for our airway management.

Phonatory effects of type I thyroplasty implant shape and depth of medialization in unilateral vocal fold paralysis

OBJECTIVES/HYPOTHESIS

Medialization thyroplasty (MT) is commonly used to treat glottic insufficiency. In this study, we investigated the phonatory effects of MT implant medialization depth and medial surface shape.

METHODS

Recurrent laryngeal nerve (RLN) and vagal paralysis were simulated in an in vivo canine. A type 1 MT was performed using a silicone elastomer implant with variable medialization depths and medial surface shapes: rectangular, V-shaped, divergent, and convergent. The effects on phonation onset flow/pressure relationships and acoustics were measured.

RESULTS

Increasing depth of medialization led to improvements in fundamental frequency (F0) range and normalization of the slope of pressure/flow relationship toward baseline activation conditions. The effects of implant medial shape also depended on depth of medialization. Outcome measures were similar among the implants at smaller medialization depths. With large medialization depths and vagal paralysis conditions, the divergent implant maintained pressure/flow relationship closer to baseline. The vagal paralysis conditions also demonstrated decreased fundamental frequency range and worse flow/pressure relationship compared to RLN paralysis.

CONCLUSIONS

The depth and medial shape of a medialization laryngoplasty (ML) implant significantly affect both the F0 range and aerodynamic power required for phonation. These effects become more notable with increasing depth of medialization. The study also illustrates that ML is less effective in vagal paralysis compared to RLN paralysis.

Incidence of laryngospasm and bronchospasm in pediatric adenotonsillectomy

OBJECTIVES/HYPOTHESIS

To evaluate and describe airway complications in pediatric adenotonsillectomy.

STUDY DESIGN

Retrospective case-control study.

METHODS

A chart review of patients that underwent adenotonsillectomy between 2006 and 2010 was performed. Perioperative complications, patient characteristics, and surgeon and anesthesia technique were recorded.

RESULTS

A total of 682 charts were reviewed. Eleven cases (1.6%) of laryngospasm were identified: one was preoperative, seven occurred in the operating room postextubation, and three occurred in the recovery area. Four patients were given succinylcholine, one was reintubated, and the other cases were managed conservatively. Mean age of patients with laryngospasm was 5.87 years (standard deviation [SD], 4.01; 1.9-15.8 years). There were 12 cases (1.8%) of bronchospasm; all were treated with nebulized albuterol. Mean age of patients with bronchospasm was 5.81 years (SD, 4.17; 1.8-14.1 years). Overall, 22 patients required antiemetics (3.3%), 19 required albuterol (2.9%), and five required racemic epinephrine (0.8%). Compared to the children without airway complications, there was no difference in age, weight, American Society of Anesthesiologists status, length of surgery, need for admission, and anesthesia technique in those that had laryngospasm. Patients with bronchospasm, compared to the patients without complications, had faster surgeries (P < .05), were more likely to have underlying asthma (P < .05), and were more likely to be admitted (P < .05). There were no unexpected admissions or other morbidities.

CONCLUSIONS

The rates of laryngospasm (1.6%) and bronchospasm (1.8%) are significantly lower than reported in the literature, reflecting refinements in modern anesthesia/surgical technique. Knowledge of at-risk patients can facilitate planning to potentially reduce the incidence of perioperative airway complications during adenotonsillectomy.
