The authors observed an acute desert-related disease when the mixture of the fine Saudi sand dust and pigeon droppings triggered a hyperergic lung condition. It was further aggravated by various kinds of organic pathogenic components contributing to an opportunistic infection of the lung. These all lead to the recognition of a new clinicopathological entity, Desert Storm pneumonitis or Al Eskan disease. For the first time, the Saudi sand dust's elemental composition was studied by ultrastructural and microanalytical means. The authors concluded that, contrary to previous beliefs, sand particles less than 1 microns (0.1 microns to 0.25 microns) in diameter are present in substantial quantities in the Saudi sand and are pathogenic, causing hyperergia. Pathogenesis of the sand dust, induced hyperergia, and its immunopathologic background are highlighted.

Discharge diagnoses from October 1, 1987 to September 30, 1988 were analyzed to quantitate infection. Four hundred forty-nine (4.8%) of 9,290 discharges (excluding 1-day stays) were infections. Pneumonia, caused by all etiological agents, was responsible for 2.4% of the principal diagnoses. These data help define the role of infection in hospitalized veterans and further supports earlier findings that respiratory tract infections are the most common of all infections in our veterans.

Extracorporeal membrane oxygenation (ECMO) is used in the treatment of reversible pulmonary disease in the newborn. The ECMO program at Wilford Hall USAF Medical Center began in 1985 and to date, 57 patients have been placed on bypass for a mean of 125 hours. The indications for ECMO are severe, prolonged hypoxemia in patients with an estimated mortality of greater than 90% using conventional ventilator support. The major diagnoses in the patients placed on ECMO were meconium aspiration, congenital diaphragmatic hernia, and neonatal sepsis or pneumonia. Overall survival was 79%, or 45 out of 57. The most frequent complications were intracranial hemorrhage as well as hemorrhage from the surgical site. We have found ECMO to be an extremely valuable adjunct in the care of the critically ill newborn and believe it can significantly improve survival in infants with reversible pulmonary disease.

Lower respiratory disease is a major source of morbidity in military recruits, with hospitalization rates for pneumonia more than 30 times that of the non-recruit population. The etiologic agent remains unknown in over 75% of cases. This study prospectively examined the etiology of pneumonia among recruits at Naval Training Center, San Diego, California. Recruits presenting with cough, fever, or shortness of breath and pulmonary infiltrates on chest X-ray were eligible for enrollment. A standardized scoring form and focused physical exam were completed on each subject. Sputum specimens were obtained for Gram's stain and culture, DNA probing for Legionella and Mycoplasma species, and direct fluorescent antibody staining for Legionella. Acute and convalescent serologies were performed for adenovirus, influenza A and B, Mycoplasma pneumoniae, Chlamydia group, and respiratory syncytial virus. Of 110 eligible patients, 100 consented to enrollment and 75 patients completed the study. Etiologic diagnoses were obtained in 40 of the patients (53%). M. pneumoniae, Haemophilus influenzae, and viruses accounted for the majority of infections. Mixed infections were seen in six patients. Forty-seven percent of patients had no diagnosis established. Pneumonia in this series of military recruits was frequently caused by M. pneumoniae and H. influenzae. Fifty percent of cases were undiagnosed with routinely available laboratory methods. Further studies are warranted to more clearly define the etiologic agents of recruit pneumonia and the utility of prophylactic measures.

A 57-year-old man was admitted to our hospital because of dyspnea and abnormal shadow on chest roentgenogram. He had received two herbal drugs: Saikokeisikankyou-tou (SKT) for one month and Licium Halimifolium Mil (LHM) for two weeks. After admission, all medication was stopped and his symptoms were gradually diminished. Transbronchial lung biopsy specimens showed interstitial pneumonia. Lymphocyte stimulation test, skin test and challenge test were positive to these herbal drugs. We diagnosed him as drug-induced pneumonitis. This is the first report on pneumonitis caused by Saikokeisikankyou-tou diagnosed by lymphocyte stimulation test, skin test and challenge test.

From August 1993 through April 1994, U.S. Marines (98% male, median age 20 years) who were hospitalized with radiographically confirmed pneumonia were prospectively studied for evidence of acute Mycoplasma pneumoniae infection. Overall, 32 (36.4%) of the 88 patients with paired sera had evidence of acute infection by an elevated immunoglobulin M titer (22.7%), a 4-fold rise in immunoglobulin G titer (9.1%), a positive polymerase chain reaction result (11.1%), and/or a positive culture (5.8%). No specific symptoms or clinical findings were strong predictors of M. pneumoniae infection. Among patients with evidence of acute M. pneumoniae infection, admitting clinicians chose other pathogens as more likely etiologic agents 46.4% of the time, and over the course of the hospitalization, 10% of patients failed to receive appropriate antibiotics. These data indicate that M. pneumoniae may cause a high proportion of pneumonias among military personnel and should be considered in empiric treatment and prophylaxis.

An outbreak of 16 cases of ciprofloxacin-resistant Acinetobacter baumannii (calcoaceticus subspecies anitratus) infections occurred during a 7-month period in a medical intensive care unit. Fifteen of the patients developed pneumonia associated with ventilator support. Possible sources considered in the outbreak investigation were sinks, ice, personnel, patients on multiple antibiotic therapy, reusable ventilator circuits, and hemodialysis. The equipment and environment associated with the outbreak were cultured. Patients on ventilators were significantly more susceptible to Acinetobacter nosocomial infection compared with the rest of the patients in the medical intensive care unit (p < 0.05). Sputum cultures were only 5% sensitive to ciprofloxacin and gentamicin, but they were 100% sensitive to imipenem (p < 0.0001). Uncloaking imipenem was a significant contributing factor in controlling this outbreak. Once outbreak control measures were instituted, Acinetobacter isolates dropped from 77 (during the outbreak year) to 9 (during the subsequent year) and no new pneumonia cases occurred.

Melioidosis is a tropical environmental hazard that causes acute and chronic pulmonary disease, abscesses of the skin and internal organs, meningitis, brain abscess and cerebritis, and acute fulminant rapidly fatal sepsis. It is more common among adults, individuals with diabetes, and individuals with chronic renal disease, but it can occur in normal hosts and children. Burkholderia pseudomellei is the most prevalent cause of community-acquired pneumonia, liver and splenic abscess, and sepsis in northeastern Thailand. Melioidosis can reactivate years after primary infection and result in chronic or acute life-threatening disease. With increasing worldwide travel and migration, patients may present in nonendemic countries with reactivation melioidosis decades after leaving an endemic region. We discuss seven selected patients presenting with this disease to a tertiary care facility in Bangkok between 1995 and 1997. Awareness should allow early diagnosis and treatment, which can lead to decreased morbidity and mortality.

Hexachloroethane (HC) smoke, also known as white smoke, is an obscurant used in numerous military situations. Many adverse health effects are associated with the use of white smoke, some of which are potentially life threatening. Inhalation is the most frequent route of injury. Two deaths among U.S. Army personnel resulted from HC smoke exposure in 1988. As recently as 1997, a United Nations soldier in Bosnia died after an HC smoke canister was discharged in his tent. Injuries are predominantly pulmonary and range from cough and dyspnea to chemical pneumonitis, pulmonary edema, and adult respiratory distress syndrome. In the case presented, a soldier developed pneumomediastinum after exposure to HC smoke. This is the first case reported in the literature of pneumomediastinum associated with HC smoke inhalation.

Low-dose methotrexate is a commonly prescribed medication for the treatment of rheumatoid arthritis and other rheumatic diseases. Its effectiveness in ameliorating the clinical symptoms and findings has been well established, and adverse effects have been relatively infrequent, particularly compared to other immunosuppressive agents. Pneumocystis carinii pneumonia is most often seen in severely immunosuppressed patients related to the acquired immunodeficiency syndrome or treatment of malignancies with potent cytotoxic agents. However, P. carinii pneumonia can occur in patients receiving low-dose methotrexate concurrent with corticosteroids, nonsteroidal anti-inflammatory drugs, renal impairment, or a combination of factors. We report 1 patient and review 10 additional cases that support this relationship.
