Extrapulmonary manifestations of Mycoplasma pneumoniae are well described, including a subset of central nervous system (CNS)-associated syndromes. In pediatric populations, frequencies of CNS sequelae occur in 0.1% to 7% of patients. Neurologic illness associated with M. pneumoniae, such as meningitis, encephalitis, polyradiculitis, Guillain-Barre, and stroke have been reported; however, the incidence of M. pneumoniae-associated organic brain syndrome is rare. We present the case of a 20-year-old midshipman with acute psychosis following resolution of M. pneumoniae pneumonia and review 6 other adult cases found in the literature. M. pneumoniae remains one of the most common causes of respiratory illnesses in the military recruit setting and therefore should always be suspected as an organic cause of mental status changes in young persons such as recruits, cadets, and midshipmen particularly with antecedent respiratory illnesses.

Adenovirus, a frequent cause of mild respiratory disease in military trainees, can result in severe manifestations when outbreaks are caused by novel viral strains for which there is little pre-existing immunity. Twenty-five basic military trainees (BMTs) were hospitalized with adenovirus pneumonia from April 1, 2007 through June 21, 2007. Clinical findings for 9 of these patients with PCR-confirmed adenovirus serotype 14 were studied retrospectively. The clinical picture was characterized by cough (88.9%) and sputum production (77.8%). All trainees were febrile. Laboratory results showed 88.9% had normal white blood cell (WBC) counts, 66.7% with high monocytes, and 55.6% with low lymphocytes on differential. All had lobar pneumonia radiographically. One patient required the intensive care unit (ICU) and later expired. In conclusion, among hospitalized patients with the combination of fever, productive cough, normal WBC, a differential showing high monocytes and low lymphocytes in an immunocompetent young adult with lobar pneumonia warrants a high level of suspicion for adenovirus 14 pneumonia.

Pneumonia is a major cause of hospital admissions and deaths worldwide. Our aim was to examine the trends in admissions for pneumonia in the Department of Veterans Affairs (VA). We examined data for the fiscal years 2002 through 2007 on patients aged 65 years and older hospitalized with pneumonia by using VA administrative databases. The numbers of hospital admissions for pneumonia were relatively stable during this period. However, length of hospital stay and 30- and 90-day mortality decreased during this period. The proportion of patients admitted to the intensive care unit remained relatively constant, but fewer received mechanical ventilation; there was substantial increase in noninvasive ventilation. In the VA, pneumonia-related admissions are being managed more effectively even as the overall number of admissions remains stable.

Community-acquired pneumonia can compromise readiness of recruits and service members operating in confined spaces. Often respiratory pathogens are implicated in outbreaks. In July 2008, 5 Basic Underwater Demolition/SEAL students entering an intense period of training at Naval Amphibious Base Coronado reported with clinical symptoms and chest radiographs consistent with pneumonia. Throat and nasal swabs were tested for respiratory pathogens. Molecular evidence indicated that they were infected with the atypical bacterium Chlamydophila pneumoniae. Thirty contemporaneous Basic Underwater Demolition/SEAL students were tested to determine the extent of C pneumoniae infection burden. Five additional cases were captured within this group. The 10 individuals diagnosed with C pneumoniae were treated with a course of azithromycin, Avelox (moxifloxacin hydrochloride), and doxycycline. The cases ended following the isolation of cases and prophylaxis with oral antibiotics. This work highlights the importance of rapid respiratory disease diagnoses to guide the clinical response following the emergence of respiratory infections among military trainees.

Traumatic brain injury or stroke causes profound suppression of the cellular immune system and short- and long-term psychological sequelae. Infection is also a common result and is likely caused by bacterial translocation from the gut. Both the bacterial translocation from the gut and the ensuing pneumonia and sepsis are ameliorated by adoptive immune therapy. Huge health care costs are incurred by brain trauma and its sequelae in our soldiers, athletes, and general population. Diffusion tensor imaging and adoptive immune therapy should become standards of care to follow the injured brain serially as it heals and as the immune suppression and infections are overcome. Brain infrastructure healing is retarded by a suppressed immune system, and the blood-brain barrier's response to trauma offers opportunity for adoptive immune therapy to enhance microglial-directed neuronal repair and maintenance.

Brugada syndrome (BS) is a cardiac rhythm disturbance that predisposes patients to sudden cardiac death. Brugada is classically described with specific electrocardiographic (EKG) findings of ST elevation and right bundle branch block in precordial leads and is an often unrecognized contributor to sudden cardiac death. We present a case of BS with cyclic EKG findings in a febrile 20-year-old active duty, Vietnamese male who presented following a witnessed syncopal event. His classic findings of Brugada pattern on EKG demonstrated reversibility with clinical defervescence. In patients with a suggestive history, a normal EKG cannot definitively rule out BS as the Brugada pattern can be unmasked by stress, which in this case was represented by a pneumonia-induced fever.

Confederate Lieutenant General Thomas J. "Stonewall" Jackson was wounded by his own men at the Battle of Chancellorsville during the American Civil War. While being removed from the field, Jackson fell from the litter and struck the right side of his chest on a large stone or stump. Four days following the amputation of his left arm, Jackson developed pneumonia in his right lung. His treating physicians believed the infection developed secondary to a pulmonary contusion that occurred when he fell from the litter. Pulmonary contusions are an independent risk factor in the development of post-traumatic pneumonia and an infection that occurs within 72 to 96 hours of injury is termed an early onset pneumonia. The nature and timing of Stonewall Jackson's illness following his wounding is consistent with the modem diagnosis of early onset pneumonia following chest trauma.

Although there is literature evaluating infectious complications associated with combat-related injuries from Iraq and Afghanistan, none have evaluated pneumonia specifically. Therefore, we assessed a series of pneumonia cases among wounded military personnel admitted to Landstuhl Regional Medical Center, and then evacuated further to participating U.S. military hospitals. Of the 423 casualties evacuated to the United States, 36 developed pneumonia (8.5%) and 30 of these (83.3%) were ventilator-associated. Restricting to 162 subjects admitted to intensive care, 30 patients had pneumonia (18.5%). The median Injury Severity Score was higher among subjects with pneumonia (23.0 vs. 6.0; p < 0.01). There were 61 first-isolate respiratory specimens recovered from 31 pneumonia subjects, of which 56.1% were gram-negative, 18.2% were gram-positive, and 18.2% were fungal. Staphylococcus aureus and Pseudomonas aeruginosa were most commonly recovered (10.6%, and 9.1%, respectively). Thirteen bacterial isolates (26.5%) were multidrug-resistant. Outcome data were available for 32 patients, of which 26 resolved their infection without progression, 5 resolved after initial progression, and 1 died. Overall, combat-injured casualties suffer a relatively high rate of pneumonia, particularly those requiring mechanical ventilation. Although gram-negative pathogens were common, S. aureus was most frequently isolated. Continued focus on pneumonia prevention strategies is necessary for improving combat care.

Acute eosinophilic pneumonia is a rare entity characterized by rapidly progressive infiltration of eosinophils into the lungs and is often associated with drug exposure or infection. We report a case of a previously healthy 19-year-old woman who presented with acute progressive dyspnea. Chest radiograph revealed diffuse bilateral infiltrates. Based on the results of bronchoalveolar lavage fluid and her clinical course, she was diagnosed as having acute eosinophilic pneumonia. We suspect that the disease was related to smoking because she had started smoking 3 weeks before the onset of symptoms. Given the high prevalence of smoking and initiation of smoking in the military population, it is important for physicians taking care of this population to be aware of this disorder.

Deployment to Southwest Asia is associated with increased airborne hazards such as geologic dusts, burn pit smoke, vehicle exhaust, or air pollution. There are numerous ongoing studies to evaluate the potential effects of inhaled particulate matter on reported increases in acute and chronic respiratory symptoms. Providers need to be aware of potential causes of pulmonary disease such as acute eosinophilic pneumonia, asthma, and vocal cord dysfunction that have been associated with deployment. Other pulmonary disorders such as interstitial lung disease are infrequently reported. Not all deployment-related respiratory complaints may result from deployment airborne hazards and a broad differential should be considered. We present the case of a military member with a prolonged deployment found to have lobar infiltrates secondary to pulmonary vein stenosis from treatment for atrial fibrillation.
