The recent COVID-19 pandemic has underscored the necessity of protecting health care providers (HCPs) against the transmission of infectious agents during dental procedures. To this end, the effectiveness of several air cleaning devices (ACDs) in reducing HCPs exposure to aerosols generated during dental procedures was estimated, separately or in combination with each other. These ACDs were a chairside unit capturing aerosols at the source of generation, and four ambient ACDs: a portable ambient ACD; a negative pressure module; a custom made, fan-operated and wall-mounted air filter (WMAF); and a smaller and passive version of the latter. The last three ACDs were intended for mobile dental clinics (MDCs) only. ⋯ This assessment suggests that the use of the tested chairside ACD, by capturing aerosols at the source of generation, had the greatest impact on reducing exposure of dental personnel to PM10 produced during dental procedures. This study also indicates that such exposure is further reduced with the addition of an ambient ACD. However, creating a negative pressure room as high as -0.25 inch wc can lead to air turbulence reducing the effectiveness of ACDs in capturing aerosols at the source. Furthermore, the presence of uncaptured droplets and spatter on the surrounding environment supports the need to complement the use of engineering controls with proper administrative controls and personal protective equipment, as recommended by governmental agencies and the scientific community for preventing the transmission of infection in health care settings.

Randomized Controlled Trial
The Effectiveness of Dexmedetomidine as a Prophylactic Treatment for Emergence Delirium Among Combat Veterans With High Anxiety: A Randomized Placebo-Controlled Trial.
Emergence delirium (ED) is characterized by agitation, confusion, and violent physical and verbal behavior associated with awakening from general anesthesia. Combat exposure among U.S. military veterans has been identified as a risk factor for ED. Preoperative baseline anxiety was shown to be a predictor of ED, and combat veterans are known to be at high risk for anxiety as well as depression and PTSD. Dexmedetomidine is an alpha-2 receptor agonist proven to mitigate ED in several patient populations. Perioperative use of dexmedetomidine demonstrated promising benefits in pediatric ED but has not been evaluated in combat veterans. ⋯ Dexmedetomidine was effective at reducing PAED among combat veterans who were experiencing symptoms of pre-operative anxiety (i.e., STAI-State ≥39). Although psychological morbidity is not unique to the military population, combat veterans carry some of the highest rates of anxiety, PTSD and depression compared to the general population. Dexmedetomidine can be safety employed by anesthesia providers to reduce symptoms of ED in the perioperative period. The double-blind randomized, controlled study design strengthens our analyses; however, this study did not control for the type of surgical procedure or the duration of anesthetic. Furthermore, we only enrolled patients with combat exposure experiencing symptoms of anxiety and did not investigate the role of dexmedetomidine in combat veterans with less anxiety. Further study of the relationship between psychological comorbidities, ED, and dexmedetomidine is warranted.

Review Case Reports
Adult-diagnosed Chronic Granulomatous Disease: The Need to Increase Awareness.
Chronic granulomatous disease is genetic disorder characterized by the inability of phagocytes to produce sufficient oxidative burst needed to kill intracellular organisms. Patients have recurrent, life-threatening infections involving multiple systems including the lungs, skin, lymph nodes, and liver. The majority of patients with chronic granulomatous disease are diagnosed in childhood although some may present in adulthood due to a milder phenotype. ⋯ She developed subsequent bacterial and fungal infections initially attributed to immunosuppressive drugs. Further evaluation revealed the diagnosis of chronic granulomatous disease. We review the diagnosis and treatment of chronic granulomatous disease in hopes to increase awareness of this disease in adulthood in order to initiate potential life-saving prophylactic antibiotics.

Randomized Controlled Trial
Non-pharmacological Home Therapies for Subacute Low Back Pain in Active Duty Military Personnel: A Randomized Controlled Trial.
Low back pain (LBP) is a major cause of visits to ambulatory care, missed duty time, and disability discharge. The subacute phase of LBP presents an opportune time to prevent chronicity and lessen recurrence. The goal of this randomized controlled trial (RCT) was to determine the relative effectiveness of neuromuscular electrical stimulation (NMES) training and a progressive exercise program (PEP) on improving physical performance, pain, and torso strength in U.S. service members with subacute LBP, compared to standard primary care management (PCM) alone. ⋯ In an active duty population with subacute LBP, integrating NMES strength training into the rehabilitation therapy may offer a modest benefit for increasing sit-ups and push-ups and improving torso strength.
