Introduction Burn pits (BPs) have been widely used by the U.S. military for waste disposal while in conflicts abroad. Significant adverse health effects are thought to be linked to BPs, but limited data exist examining the impact on the respiratory tract. The purpose of this systematic review is to characterize these effects on both the upper respiratory tract (URT) and lower respiratory tract (LRT). Materials and Methods A systematic review was performed according to the Preferred Reporting Items for Systematic Reviews and Meta-Analysis guidelines on articles published from January 1, 2001, through November 2020. PubMed, EMBASE, and Ovid MEDLINE databases were queried for studies examining the effect of BPs on the URT and LRT of service members. Results A total of 288 articles were identified, with nine meeting inclusion criteria. Eight of the nine articles assessed the LRT, one examined the URT alone, and two examined both the URT and LRT. Outcome measures were heterogeneous across all studies, precluding meta-analysis. Patient-reported LRT diagnoses appeared to increase as exposure to BPs increased. There are very limited data assessing the impact of BP exposure on the URT. No association between BP exposure and objective measures of LRT or URT disease was identified. Conclusion Service members deployed to combat zones seem to report a significant increase in respiratory diseases following exposure to BPs, although definitive conclusions are limited by multiple airborne exposures and varied reporting methods. Self-reported LRT diagnoses appear to be more prevalent. There is a paucity of data on the effects of BPs on the URT. Objective measures of disease do not appear to correlate with patient reports. Prospective, long-term, and outcome-based studies are necessary to examine the effects of BPs, and other airborne hazards related to deployment, on the URT and LRT of service members.

Objective Following thyroid lobectomy, patients are at risk for hypothyroidism. This study sought to determine the incidence of postlobectomy thyroid hormone replacement as well as predictive risk factors to better counsel patients. Study Design Retrospective cohort study. Setting Patients aged 18 to 75 years treated in a single academic institution who underwent thyroid lobectomy from October 2006 to September 2017. Methods Patients were followed for an average of 73 months. Demographic data, body mass index, size of removed and remnant lobe, preoperative thyroid-stimulating hormone (TSH) level, final thyroid pathology, and presence of thyroiditis were collected and analyzed. Risk factors were evaluated with chi-square analyses, t tests, logistic regression, and Kaplan-Meier analysis. Results Of the 478 patients reviewed, 369 were included in the analysis, 30% of whom eventually required thyroid hormone replacement. More than 39% started therapy >12 months postoperatively, with 90% treated within 36 months. Patient age ≥50 years and preoperative TSH ≥2.5 mIU/L were associated with odds ratios of 2.034 and 3.827, respectively, for thyroid hormone replacement. Malignancy on final pathology demonstrated an odds ratio of 7.76 for hormone replacement. Sex, body mass index, volume of resected and remaining lobes, and weight of resected lobe were not significant predictors. Conclusion Nearly a third of patients may ultimately require thyroid hormone replacement. Age at the time of surgery, preoperative TSH, and final pathology are strong, clinically relevant predictors of the need for future thyroid hormone replacement. After lobectomy, patients should have long-term thyroid function follow-up to monitor for delayed hypothyroidism.

Hundreds of thousands of US Service Members have been exposed to deployment-related burn pits. This novel study demonstrates that individuals with burn pit exposure experience significantly worse quality of life and more severe objective sinus disease on exam, implying that this environmental exposure contributes to the development of chronic sinusitis.

situations. Obstructive masses of the head and neck in the fetus present a difficult and potentially fatal clinical problem. Based on our experience, we offer the otolaryngologist a structured and well-choreographed approach in dealing with such complex situations, with the incorporation of a comprehensive checklist for EXIT procedures.

In December of 2019, a novel virus known as severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) produced a cluster of viral pneumonia cases in Wuhan, China. In the United States (US), New York City was particularly devastated, with the volume and acuity of patients placing an unprecedented strain on the hospital system and health care workers. In response to this crisis, USNS Comfort (T-AH 20) was deployed to New York City with a 1100 member medical team to augment local hospitals. Comfort's mission to New York City was dynamic, and required special adaptation to care for both COVID positive and COVID negative patients. Neuroplastic surgery procedures were indicated in both COVID positive and COVID negative patients, and lessons learned with regard to performance of complex surgery in an unfamiliar environment consisted of developing a thorough understanding of ones capabilities, and working with a highly skilled team of Navy surgeons, anesthesiologists, and surgical support staff, in order to provide high quality care in a deployment platform.
