Two young men, aged 34 and 30 years, developed transient recurrent multifocal neurological symptoms with associated severe headache over a 2-week period. Both had a lymphocytic pleocytosis in their cerebrospinal fluid. Cranial imaging studies were normal. All symptoms resolved without recurrence. Although the cause and pathogenesis are undefined, this self-limited benign neurological syndrome may be more common than previously recognized and has a predilection for young adult men.

A case of human ehrlichiosis (caused by infection with Ehrlichia chaffeensis) is presented. The patient was a female Naval Academy midshipman with a 26-day history of daily field training with the U.S. Marines near Quantico, Virginia. She presented with a several-day history of myalgias, fever, and frontal headache. During her clinical course, she developed fever to 104 degrees F, dry cough, dyspnea on exertion, arthralgias, and nephrotic syndrome. She did not develop a rash. Laboratory studies were significant for thrombocytopenia, equivocal Lyme enzyme immunosorbent assay with a negative confirmatory western immunoblot, equivocal Rocky Mountain spotted fever acute serology without a convalescent increase in immunoglobulin G, and immunoglobulin G/immunoglobulin M serology positive for human monocytic ehrlichiosis. She manifested known sequelae for this emerging disease, including dyspnea, pedal edema, increased transminases, and nephrotic syndrome.

The general public, the mass media, and many government officials believe that the use of weapons of mass destruction (WMD) will inevitably lead to mass panic and/or mass hysteria. However, studies of disasters and wars show that disorganized flight in the presence of a real or perceived danger (i.e., mass panic) is rare. On the other hand, in a real or perceived WMD scenario, outbreaks of multiple unexplained symptoms (i.e., mass psychogenic illness, mass sociogenic illness, mass hysteria, or epidemic hysteria) may be prevalent. Many of the symptoms (fatigue, nausea, vomiting, headache, dizziness/lightheadedness, and anorexia) are common in combat and after toxic chemical exposure, chemical weapon exposure, prodromal infectious illness, and acute radiation sickness.

An epidemic of Q fever was identified among soldiers from the Czech Republic serving in the U.N. Stabilization Force in Bosnia and Herzogovina in 1997. There were 26 serologically confirmed infections, or 4.6% of those exposed. There were 14 cases of febrile illness and 12 subclinical infections. Prodromal symptoms of malaise, headache, backache, and fatigue were followed by fever > or = 39 degrees C with an intermittent course. Physical findings were unremarkable except in five cases with radiographically confirmed pneumonia. Cases were treated with doxycycline, trimethoprim-sulfamethoxazole, or ceftriaxone and supportive care. Q fever occurred at four U.N. Stabilization Force bases with the highest incidence at Dolna Ljubija (attack rate 9.4% vs. 2.3% at other locations (risk ratio = 4.0; 95% confidence interval [CI] = 2.7-5.9; p < 0.05). A sheep farm with active lambing was located 100 m from the base. Helicopter operations at a nearby landing zone may have generated infectious environmental aerosols and may have been a cause of the Q fever outbreak.

Between 1954 and 1973, more than 2000 men entering military service as conscientious objectors participated in Project Whitecoat as medical research volunteers for the Army's biological warfare defense program. An assessment of self-reported, current health status among 358 "exposed" individuals and 164 unexposed control subjects found no conclusive evidence that receipt of investigational agents was related to adverse health outcomes. No differences in current overall health, current exercise levels, self-reported symptoms, and self-reported medical conditions were seen between the study groups. Possible associations were seen between exposure to antibiotics or other biological agents and self-reported asthma (13.0% vs. 2.4%, relative risk [RR] = 6.00, 95% confidence interval [CI] = 1.03-34.90, p = 0.050), as well as between receipt of tularemia vaccine(s) and self-reported asthma (13.3% vs. 2.4%, RR = 6.15, 95% CI = 1.03-36.70, p = 0.049) and increased frequency/severity of headaches (35.6% vs. 18.3%, RR = 2.46, 95% CI = 0.99-6.15, p = 0.074). However, the size of the population under study was insufficient to assert with confidence that these statistical associations are real.

Use of antimalarial prophylaxis continues to be routine practice among military personnel returning from areas where malaria is endemic. Primaquine may be used for terminal prophylaxis against Plasmodium ovale and Plasmodium vivax. Serious complications of this regimen are infrequent. We report the occurrence of significant hemolytic anemia for two soldiers returning from Operation Iraqi Freedom. They presented with dark urine, headaches, and classic laboratory findings of hemolysis. Both soldiers were subsequently found to have glucose-6-phosphate dehydrogenase deficiency, and both responded to conservative treatment and cessation of medication. Although this complication is unusual, medical personnel involved in the care of recently returned deployed service members should be alert to its potential occurrence among patients who are receiving antimalarial prophylaxis. This complication could be completely avoided with prescreening of personnel for glucose-6-phosphate dehydrogenase deficiency, as is currently done in the Air Force and Navy, before the use of primaquine.

The purpose of this study was to determine the concentrations and precise isotopic compositions of four uranium isotopes (234U, 235U, 236U, and 238U) in urine specimens from the civilian population of Afghanistan after Allied Forces Operation Enduring Freedom. Eight male civilians from Nangarhar-Jalalabad region who presented with symptoms of fatigue, fever, musculoskeletal and neurological alterations, headaches, and respiratory impairment after inhalation of dust during the bombing raids in June 2002 had urine samples collected under controlled conditions and analyzed in duplicate for 234U, 235U, 236U, and 238U, with multicollector, inductively coupled, plasma ionization mass spectrometry. Control samples with an internal urine standard were analyzed with the same method. The mean concentration of uranium in eight samples was found to be considerably greater (275.04 ng/L; SD, 137.80 ng/L; SE, 48.72 ng/L) than what is regarded as a reference range (1-20 ng/L). The 238U/235U ratio was 137.87 +/- 0.20, which is consistent with that of natural uranium. The 234U/238U ratio for the Afghan samples was 0.000055 +/- 0.000001, also consistent with natural uranium. 236U, which usually forms a component of depleted uranium, was not detected (measured 236U/ 238U ratio, < 10(-7)). Our results demonstrate that contamination in Afghanistan with a source consistent with natural uranium has resulted in total uranium concentrations up to 100 times higher than the normal range for various geographic and environmental areas throughout the world. The cause of our findings is currently being evaluated as a part of our ongoing research.

Arnold-Chiari I malformation (Chiari I) is a congenital disorder characterized by caudal herniation of cerebellar tonsils through the foramen magnum. The symptoms and signs include headaches precipitated by coughing or exertion, dizziness, visual or oculomotor symptoms, dysphagia, trunk or extremity dysesthesias, ataxia, and drop attacks indicating cerebellar or cervical cord lesion. The symptoms may be provoked by increased intracranial pressure. The mean age of onset of symptoms is 25 years; consequently, previously unidentified Chiari I malformations occur in military personnel. Chiari I is associated with deaths following minor trauma, with acute respiratory failure, and with transient quadriparesis occurring in contact sports. Furthermore, Chiari I symptoms may be aggravated by chiropractic manipulation. This report describes symptoms and signs of Chiari I in four military conscripts in the Finnish Defense Forces. It is important to detect Chiari I in military personnel to establish appropriate service fitness and safety for these patients.

The case of a 24-year-old male U.S. Marine Corps sergeant who presented with headache and ataxia to a combat support hospital (CSH) in Kuwait, during Operation Iraqi Freedom, is described. Imaging studies revealed a cystic brain neoplasm causing hydrocephalus and increased intracranial pressure. Because of the patient's deteriorating clinical condition and the high risk of further brain injury during a prolonged air evacuation flight, immediate surgery at the CSH was deemed the safest treatment option. The tumor was completely removed and the patient's symptoms resolved, allowing safe evacuation. A CSH is not intended to provide comprehensive neurosurgical capabilities and some equipment usually considered necessary to perform this surgery was unavailable, but field-expedient methods were devised to overcome these deficiencies. This is the first reported case of a brain tumor successfully removed in a CSH.

This study surveyed health care providers about their evaluation and treatment of mild traumatic brain injury (TBI) in adults. We presented two vignettes describing mild TBI cases to staff in the emergency department (N = 22) and primary care clinics (N = 16) at Wilford Hall Air Force Medical Center and asked how they would evaluate and treat these patients. Most providers said they would assess visual changes, nausea/vomiting, headache, and neck pain. More emergency department personnel than primary care clinic providers would make referrals to different specialties, whereas more primary care clinic providers would schedule a follow-up appointment. Neither group of providers mentioned assessing common postconcussive symptoms of fatigue, emotional changes, and problems sleeping. Comparing findings to current literature suggest that added focus on emotional, cognitive and psychosocial factors, and education of the patient and family could improve early identification of mild TBI patients at risk for poor recovery.
