In early 1992, U.S. troops returning from the Gulf War began reporting a variety of nonspecific symptoms such as fatigue, skin rash, headache, muscle and joint pain, and loss of memory. These reports marked the beginning of what was to be identified as the Gulf War Syndrome (GWS). In the years since the war, as many as 100,000 troops have claimed they suffer from this mysterious disease. In our culture, the existence of disease as a specific entity is fundamental to ensuring the validity of that disease. The legitimacy of GWS has been repeatedly called into question because no specific physiological etiology has been confirmed, and it is becoming more and more likely that the origin of GWS will never be clearly delineated. The purpose of this paper is to illustrate the complicated process of defining GWS as a legitimate illness in the absence of etiological evidence and to suggest a method of treatment for individuals who still suffer from its sequelae.

A survey study using questionnaire was conducted in 530 people (270 men, 260 women) living or not in vicinity of cellular phone base stations, on 18 Non Specific Health Symptoms. Comparisons of complaints frequencies (CHI-SQUARE test with Yates correction) in relation with distance from base station and sex, show significant (p < 0.05) increase as compared to people living > 300 m or not exposed to base station, till 300 m for tiredness, 200 m for headache, sleep disturbance, discomfort, etc. 100 m for irritability, depression, loss of memory, dizziness, libido decrease, etc. Women significantly more often than men (p < 0.05) complained of headache, nausea, loss of appetite, sleep disturbance, depression, discomfort and visual perturbations. This first study on symptoms experienced by people living in vicinity of base stations shows that, in view of radioprotection, minimal distance of people from cellular phone base stations should not be < 300 m.

Indoor air contamination with toxic opportunistic molds is an emerging health risk worldwide. Some of the opportunistic molds include: Stachybotrys chartarum, Aspergillus species (A. fumigatus, A. flavus, A. niger, A. versicolor etc.), Cadosporium, Alternaria, Penicillium, Trichoderma, Fusarium graminearum etc. These molds flourish in homes that are moist and damp. Reports of floods are now evident in many parts of the world. With these global changes in climatic conditions that favor the opportunistic mode of living among these molds, some health authorities are beginning to feel concerned about the diversity and the extent to which opportunistic molds can cause adverse health effects in humans. Mycotoxicosis is the collective name for all the diseases caused by toxic molds. Frequently, we have cases of acoustic neuroma due to mycotoxicity in our Center. Mycotic neuroma probably has not been reported before and the application of brainstem auditory evoked response (BAER) techniques in acoustic mycotic neuroma have not been reported either. The aim of this study, therefore, was to report cases and measurements of acoustic mycotic neuroma in adolescents using the brainstem auditory evoked response. The patients' case history, clinical neurological and neurobehavioral questionnaires were assessed. Then, the BAERs were recorded between Cz and Ai, with a second channel, Cz-Ac. The case histories and the questionnaires were analyzed in conjunction with the outcome of the objective brainstem auditory evoked response measurements. The prevalent subjective findings in the patients were headaches, memory loss, hearing loss, lack of concentration, fatigue, sleep disturbance, facial swelling, rashes, nosebleeds, diarrhea, abdominal pains and respiratory difficulties. Objective BAER showed overall abnormalities in all the patients. Although the waveform abnormalities varied, 1-3 interpeak latencies were abnormal in all the patients. Overall results showed the presence of acoustic mycotic neuroma and confirmed the sensitivity and usefulness of BAER in screening acoustic mycotic neuroma and sensorineural auditory dysfunction.

The internal contamination with depleted uranium (DU) isotopes was detected in British, Canadian, and United States Gulf War veterans as late as nine years after inhalational exposure to radioactive dust in the Persian Gulf War I. DU isotopes were also identified in a Canadian veteran's autopsy samples of lung, liver, kidney, and bone. In soil samples from Kosovo, hundreds of particles, mostly less than 5 microm in size, were found in milligram quantities. Gulf War I in 1991 resulted in 350 metric tons of DU deposited in the environment and 3-6 million grams of DU aerosol released into the atmosphere. Its legacy, Gulf War disease, is a complex, progressive, incapacitating multiorgan system disorder. The symptoms include incapacitating fatigue, musculoskeletel and joint pains, headaches, neuropsychiatric disorders, affect changes, confusion, visual problems, changes of gait, loss of memory, lymphadenopathies, respiratory impairment, impotence, and urinary tract morphological and functional alterations. Current understanding of its etiology seems far from being adequate. After the Afghanistan Operation Anaconda (2002), our team studied the population of Jalalabad, Spin Gar, Tora Bora, and Kabul areas, and identified civilians with the symptoms similar to those of Gulf War syndrome. Twenty-four-hour urine samples from 8 symptomatic subjects were collected by the following criteria: 1) the onset of symptoms relative to the bombing raids; 2) physical presence in the area of the bombing; and 3) clinical manifestations. Control subjects were selected among the sympotom-free residents in non-targeted areas. All samples were analyzed for the concentration and ratio of four uranium isotopes, (234)U, (235)U, (236)U and (238)U, by using a multicollector, inductively coupled plasma ionization mass spectrometry. The first results from the Jalalabad province revealed urinary excretion of total uranium in all subjects significantly exceeding the values in the nonexposed population. The analysis of the isotopic ratios identified non-depleted uranium. Studies of specimens collected in 2002 revealed uranium concentrations up to 200 times higher in the districts of Tora Bora, Yaka Toot, Lal Mal, Makam Khan Farm, Arda Farm, Bibi Mahro, Poli Cherki, and the Kabul airport than in the control population. Uranium levels in the soil samples from the bombsites show values two to three times higher than worldwide concentration levels of 2 to 3 mg/kg and significantly higher concentrations in water than the World Health Organization maximum permissible levels. This growing body of evidence undoubtedly puts the problem of prevention and solution of the DU contamination high on the priority list.

We examine Gulf War illnesses--which include the fatigue, joint pain, dermatitis, headaches, memory loss, blurred vision, diarrhea, and other symptoms reported by Gulf War veterans--in relation to other medically unexplained physical symptoms such as multiple chemical sensitivity, chronic fatigue syndrome, and fibromyalgia. Our intent is to examine the diagnosis negotiations involved in these mysterious diseases, by showing the different forms of legitimacy involved in such interactions. Factors involved in diagnostic legitimacy are: diagnostic legitimacy in the medical community, lay acceptance of the diagnosis, uncertainty in looking for causes, and social mobilization. We conclude by noting that research may not be able to find any cause for these diseases/conditions; hence, it may be necessary to embrace medical uncertainty, and also to accept patient experience in order to facilitate diagnosis, treatment, and recovery process. Such a change can alter patients' expectations and taken-for-granted assumptions about medicine, and perhaps in turn reduce the frequency with which dissatisfied individuals form illness groups that mobilize to challenge what they see as an unresponsive medical system.

This paper analyzes and presents the biochemical abnormalities in the sera of patients presenting with chronic mycosis in order to investigate the relationship with the risks of multiple renal disorders. The study population (n = 10) consisted of six females and four males (mean age 36.3 years) exposed by toxic molds in their homes and offices for an average of 2.8 years. The control group comprised ten people, five males and five females (mean age 35.9 years) without any known exposures to toxic molds. Blood samples were obtained from both the patients and the controls and were processed using specific biochemical methods that included enzyme-linked immunoabsorbent assay (ELISA). There were biochemical abnormal concentrations in creatinine, uric acid, phosphorus, alkaline phosphotase, cholesterol, HDH, SGOT/AST, segmented neutrophils, lymphocytes, total T3, IgG and IgA immunoglobulins with significant differences between patients and controls. These abnormalities were consistent with multiple renal disorders. The major complaints of the mycosis patients were headaches, pulmonary symptoms, allergic reactions, memory loss, skin rashes, blurred vision symptoms, fatigue, and runny nose. These findings were depictive of a strong association of chronic mycosis with abnormal renal indicators. It was concluded that, although this research was a pilot investigation, based on the overall results, people exposed to chronic indoor environmental toxic molds were at risk of multiple renal complications.

Toxigenic mold activities produce metabolites that are either broad-spectrum antibiotics or mycotoxins that are cytotoxic. Indoor environmental exposure to these toxigenic molds leads to adverse health conditions with the main outcome measure of frequent neuroimmunologic and behavioral consequences. One of the immune system disorders found in patients presenting with toxigenic mold exposure is an abnormal natural killer cell activity. This paper presents an overview of the neurological significance of abnormal natural killer cell (NKC) activity in chronic toxigenic mold exposure. A comprehensive review of the literature was carried out to evaluate and assess the conditions under which the immune system could be dysfunctionally interfered with leading to abnormal NKC activity and the involvement of mycotoxins in these processes. The functions, mechanism, the factors that influence NKC activities, and the roles of mycotoxins in NKCs were cited wherever necessary. The major presentations are headache, general debilitating pains, nose bleeding, fevers with body temperatures up to 40 degrees C (104 degrees F), cough, memory loss, depression, mood swings, sleep disturbances, anxiety, chronic fatigue, vertigo/dizziness, and in some cases, seizures. Although sleep is commonly considered a restorative process that is important for the proper functioning of the immune system, it could be disturbed by mycotoxins. Most likely, mycotoxins exert some rigorous effects on the circadian rhythmic processes resulting in sleep deprivation to which an acute and transient increase in NKC activity is observed. Depression, psychological stress, tissue injuries, malignancies, carcinogenesis, chronic fatigue syndrome, and experimental allergic encephalomyelitis could be induced at very low physiological concentrations by mycotoxin-induced NKC activity. In the light of this review, it is concluded that chronic exposures to toxigenic mold could lead to abnormal NKC activity with a wide range of neurological consequences, some of which were headache, general debilitating pains, fever, cough, memory loss, depression, mood swings, sleep disturbances, anxiety, chronic fatigue, and seizures.

From 1996 to 2000, high-dose chemotherapy with haematopoietic stem-cell support was used as an adjuvant treatment strategy for management of primary high-risk breast cancer patients with more than five positive nodes. This single institution study included 52 women aged < or = 56 years with primary operable breast cancer and > or = 6 tumour-positive axillary lymph nodes. The treatment regimen consisted of at least three initial courses of FEC (5-fluorouracil, epirubicin, cyclophosphamide) followed by high-dose chemotherapy (cyclophosphamide, thiotepa, carboplatin) supported by autologous peripheral blood stem-cell reinfusion. This study focuses on quality control including evaluation of toxicity, supportive therapy and assessment of the stem-cell products. Cytokeratin 19 positive cells were found in the stem-cell product from 3/37 patients. Data regarding organ toxicity were used for evaluation of short- and long-term side effects. Substantial acute toxicity and frequent catheter-related infections were found. Long-term toxicities included reduced lung diffusion capacity (n = 36), fatigue (n = 14), arthralgia/myalgia (n = 10), neurotoxicity (n = 9) and memory loss (n = 4). However, most toxicities were grade 1-2 and reversible within two years. No treatment-related death occurred. Within a median follow-up of 30 months (range, 11-57), 25% of the patients had relapsed. Recurrence-free survival was 75% and overall survival was 88% three years after the start of treatment. Overall, high-dose chemotherapy was relatively well tolerated, with manageable toxicity and an acceptable requirement of supportive therapy. Until now, high-dose chemotherapy has not proven superior to conventional-dose adjuvant chemotherapy, therefore it is necessary in the future to focus on well-designed randomized studies.

The purpose of this study was to identify the major problems and associated feelings experienced by family caregivers of stroke survivors during the first month after returning home. Safety, difficulty in managing activities of daily living, and cognitive, behavioral and emotional changes of stroke survivors (for example, mood swings, lack of motivation, forgetfulness and memory loss, depression and calling the caregiver often) were the three most common problems experienced by caregivers during the first month. Other problems were loss of caregiver independence, confinement, tiredness and inadequate time to do caregiving tasks as well as managing stroke survivor physical symptoms, for example, pain, not eating and skin problems. The first month of caregiving is very dynamic and distressful for caregivers of stroke survivors and telephone contacts appear to be beneficial in assisting caregivers to cope with the caregiving process.

The development of new chemotherapeutic agents and regimens has contributed to reduced risk of cancer recurrence and prolonged patient survival. However, mild cognitive impairment (MCI), also known as ''chemofog'' or ''chemobrain'' following adjuvant chemotherapy for breast cancer has been reported since the late 1980s. Unfortunately, little is known about it's mechanism, type, severity, and episode length. This article reviewed related studies on the subject, and found that chemotherapy-induced MCI appears to occur in 10-40% of patients, and memory loss and lack of concentration are the most frequent symptoms. The symptoms are apparently transient, but take at least several years to disappear. Reviewed studies show a lack of clear understanding of what causes MCI directly. There is also a lack of consistency in symptom measurement. We point to the need to conduct well-designed studies which begin with a proper hypothesis. Future research needs to be randomized and longitudinal with a base measurement point before the chemotherapy cycle starts. Future studies must adopt an effective and sensitive method to measure MCI. The latest imaging technique, positron emission tomography (PET) may be a powerful tool. Also, all confounding factors, such as age, education, intelligence quotient (IQ), fatigue and depression, hormonal therapy and other treatments should be controlled within the study design. It is hoped that the results of such future studies will allow medical professionals to contemplate effective prevention, treatment and rehabilitation for MCI.
