One hundred and thirty-five soldiers attending a 10-week training course in the Brecon Beacons were divided into three groups, each of which sat a different kit of five tests taken from the Kit of Factor-Referenced Cognitive Tests (Ekstrom et al., 1976). The tests were given three times, with the first administration serving as a baseline, and the second and third administrations being completed after exercises involving either two nights' loss of sleep, or a physically fatiguing day. The experimental design allows the effects of practice and physical fatigue to be taken into account, and measures of the cognitive effects of sleep loss are obtained for each test. The results show that tests adversely affected by sleep loss are those that involve visual encoding and scanning, production of novel responses, as well as those in which lapses of attention critically affect performance. Performance on tests which involved logical thought and reasoning did not suffer, and in some cases improved.

Chronic fatigue syndrome (CFS) is a syndrome of uncertain etiopathogenesis characterized by disabling fatigue associated with a variable number of somatic and/or neuropsychologic symptoms. In patients with CFS, several immunologic abnormalities can be detected, including a higher prevalance of allergy. The aim of this study was to determine whether CFS patients, well studied for their allergy profile, show signs of eosinophil activation, as detectable by the measurement in serum of eosinophil cationic protein (ECP) levels. In 35 consecutive CFS outpatients (diagnosis based on the Centers for Disease Control case definition), ECP was measured in serum by a competitive enzyme immunoassay (ECP-FEIA kit, Kabi Pharmacia Diagnostics, Uppsala, Sweden). Fourteen disease-free subjects with no history of CFS or allergy were selected as controls. ECP serum levels were significantly higher in CFS patients than in controls (18.0 +/- 11.3 micrograms/l vs 7.3 +/- 2.1 micrograms/l; P < 0.01). In the CFS population, the prevalence of RAST positivity to one or more allergens was 77%, while no control showed positive RAST. Twelve of the 14 CFS patients with increased ECP serum levels were RAST-positive. However, CFS RAST-positive patients had no significantly higher ECP serum levels than CFS RAST-negative patients (19.3 +/- 12.4 micrograms/l vs 13.6 +/- 3.7 micrograms/l; P = 0.4). This is the first report of increased serum levels of ECP in CFS. On the basis of the available data, it is discussed whether eosinophil activation has a pathogenetic role in CFS or is linked to the frequently associated allergic condition, or, finally, whether a common immunologic background may exist for both atopy and CFS.

The number of road vehicle accidents during travel outside Europe and/or under difficult conditions increases about 5% every year. Road accidents account for a third to half of medical evacuations as well as for the most serious injuries. The risk of accidents and their potential gravity may be enhanced by the poor condition of roads and vehicles. Personal factors including fatigue, speed, alcohol, drugs, and poor vision also play a major role. Physicians should warn travelers planning road trips of all these hazards and of any specific local conditions prevailing in certain destinations. Prevention depends on the age of the traveler and on any disabilities that he/she might have. Packing a first aid kit and inspecting safety equipment before the trip and at regular intervals during the trip are indispensable. Knowledge of emergency first aid procedures is highly recommendable. While avoiding excessiveness of any kind, the physician should encourage suitable psychological and material preparation in function of travel plans. This preparation should be aimed at reducing the risk of road accident particularly in developing countries. Counseling can be useful in reducing the risk of road accidents particularly in developing countries.

We experienced a case of hepatic arterial infusion chemotherapy using docetaxel for liver metastasis, which showed no response to CEF therapy, from breast cancer. A 63-year-old woman had undergone modified radical mastectomy for right breast cancer (T2aN1bM0: Stage II) in October, 1995. Six-cycle CMF therapy and toremifene citrate (40 mg/day) were administered as adjuvant therapy, but multiple recurrent tumors in liver, lung, and local site were detected in February 1997. Six-cycle CEF therapy was given for recurrent disease and there was a complete response for lung and local recurrence, but no change in liver metastasis. Chemoendocrine therapies using 5'-DFUR or CMitF in addition to TAM and fadrozole hydrochloride hydrate had developed progressive disease for liver metastasis. A catheter and port kit were operatively inserted and implanted in March 1998. Hepatic arterial infusion of docetaxel (30-40 mg/body/month, one hour administration) was repeated 4 times, once in our clinic. Leukopenia, general fatigue and fever, which were mild and did not require any treatment, appeared as side effects. This treatment reduced multiple liver metastatic sites on abdominal CT finding and was thought to be a partial response. However, the patient had multiple brain metastasis and died on August 2, 1998. While docetaxel, even by systemic administration, has a 36-77% response rate for liver metastasis, arterial infusion might have a good response and mild side effect with a lower dose than by intravenous administration.

The highest body temperature and clinical symptoms during the influenza infection were analyzed on 2,145 patients with influenza, (type A: 1,408cases, type B: 737cases: confirmed by a rapid diagnosis kit, Capilia FluA, B), and for 670 patients with a negative response to the rapid diagnosis kit (controls). The study was a multi-center study of the 2002-2003 influenza season. The percentages of patients with fever over 38 degrees C, 38.5 degrees C and 39 degrees C were significantly higher in influenza A than in influenza B or controls (16-64 yrs). Over 80% of the patients in all age groups of 0-6 yrs, 7-15 yrs, 16-64 yrs or over 64 yrs with influenza A or B had a cough. The percentage of patients with cough was significantly higher for patients with influenza A or B than for controls under 65 yrs. The percentages of influenza A or B patients with rhinorrhea or loss of appetite were significantly higher than in controls under 65 yrs. The percentage of patients reporting fatigue, headache or myalgia was significantly higher for influenza A than for controls of 16-64 yrs. Differences in symptoms, including fever, were minimal between influenza A and B patients under 16 yrs, and also among influenza A, B and controls in patients over 64 yrs. The percentage of patients with cough was not different among the three age groups by influenza A or B. However, the percentage of patients with rhinorrhea, loss of appetite, vomiting or diarrhea was higher in children under 16 yrs than in adults aged 16-64 yrs in influenza A or B. In conclusion, consideration must be given to the patient's age and the type of influenza when doing a symptomatic diagnosis of influenza. In addition, the use of a rapid diagnosis kit seems necessary for the diagnosis of influenza in elderly patients, who may have no specific symptoms of influenza.

A 6-year-old boy was hospitalized because of dark feces and facial pallor of 1 weeks duration. Other gastrointestinal symptoms, including vomiting and abdominal pain, were absent, but he felt dizziness when standing and fatigue on effort. Hematologic studies revealed iron-deficiency anemia, and endoscopy showed gastric erosions and a duodenal ulcer. All test results for Helicobacter pylori infection, including H. pylori antigen in stool, anti-H. pylori IgG immunoassay in serum, and the (13)C-urea breath test, were positive. Because an H. pylori-associated gastric ulcer had been diagnosed with endoscopy in the patients father 3 years earlier, father-son transmission was suspected. The patient was treated with triple-agent eradication therapy (proton pump inhibitor [lansoprazol], amoxicillin, and clarithromycin) for 2 weeks. One month after therapy was completed, eradication of H. pylori was confirmed by negative results on the stool antigen test. Peptic ulcer disease can occur in young children, as in this case. The stool antigen test kit is a useful and reliable method that can be used even in preschool children to diagnose H. pylori infection.

The objectives of the present study were to evaluate the presence of antipolymer antibody (APA) seropositivity in 285 Italian patients affected by primary fibromyalgia (FM) and to verify whether APA levels correlate with disease severity and with cytokine levels.APA levels were determined on serum samples by an indirect ELISA kit that detects IgG APA. Cytokines (IL-1, IL-6, IL-8, IL-10 and TNFalpha) were measured by ELISA in plasma. The impact of FM on the quality of life was estimated using the Fibromyalgia Impact Questionnaire, while pain severity was evaluated using a visual analogic scale. Patients were also characterized by the presence of tiredness, stiffness, nonrestorative sleep, anxiety, depression, tension headache, irritable bowel syndrome, temporomandibular dysfunction and Raynaud's phenomena. Using a cut-off value of 30 U, APA-positive values were detected in 60 FM patients (21.05%) and in 15 healthy control individuals (15.00%) without significant differences among their levels or the percentage of seropositivity. FM patients with moderate and severe symptoms had slightly higher APA levels with respect to patients with mild symptoms. APA-seropositive patients exhibited significant correlations between APA levels and the Fibromyalgia Impact Questionnaire estimate (P = 0.042), tiredness (P = 0.003) and IL-1 levels (P = 0.0072). In conclusion, APA cannot be considered a marker of disease in Italian FM patients. The presence of APA, however, might permit the identification of a subset of FM patients with more severe symptoms and of patients who may respond differently to different therapeutic strategies.

The aim was to study the effect of job task and fast backward-rotating shifts on the time-of-day variations of cortisol, fatigue, and sleep disturbances in broadcasting sound engineers. The concentration of saliva cortisol and ratings of stress, sleepiness, and fatigue were followed at 3-hour intervals during the fast backward-rotating shifts in 26 sound engineers: 14 subjects from control rooms, aged 45.1 +/- 7.3 years, and 12 subjects working in direct transmissions, aged 51.7 +/- 6.0 years. Saliva cortisol was assessed using an radioimmunology kit. The participants reported for stress symptoms after the shifts and filled a sleep diary. The effects of job task, shift, and time-of-day were analyzed by tests of between-subjects effects (SPSS). Cortisol retained the typical diurnal pattern with a highly significant effect of the shift. The job task and the shift interacted significantly. Higher cortisol values during the morning and night shifts in engineers working in direct transmissions were found. Their stress ratings were also higher, as well as the ratings of sleepiness and fatigue. The quality of sleep was worse in engineers working in direct transmissions. In conclusion, our data indicate that stress and fast backward-rotating shifts in sound engineers working in direct transmissions affect physiological stress markers such as cortisol and increase sleepiness, fatigue, and sleep problems.

Electroacupuncture (EA) and manual acupuncture (MA) have therapeutic effects on muscle fatigue in muscle disease. The deficiencies of carnitine and glutathione induce muscle fatigue. This report investigated the effects of EA and MA on carnitine and glutathione in muscle. After the mice of EA group were fixed in the animal cage, right Zusanli (ST36) and Jiexi (ST41) were acupunctured and stimulated with uniform reinforcing and reducing method by twirling the acupuncture needle for 15 min. And then, the needle handles were connected to an electric stimulator for stimulating the acupoint with dense-sparse waves. After the mice of MA group were fixed in an animal cage, right ST36 and ST41 were acupunctured and allowed for 15 min. The mice of normal control group were not acupunctured and stimulated for 15 min. The mice of all groups were killed for collecting muscle tissue 1 h after the final treatment. Carnitine and glutathione in homogenate of muscle tissue were determined with carnitine (Kainos Laboratories Co., Tokyo, Japan) and glutathione assay kit (Dojin Chemicals Co., Kumamoto, Japan). Carnitine level in muscle tissue of MA group was significantly higher than those of EA group and normal control group. Carnitine level in muscle tissue of EA group was not significantly different from that of normal control group. Glutathione levels in muscle tissue of EA group and MA group were significantly higher than that of normal control group. This report presented that carnitine in muscle is increased by MA, and not increased by EA, and that glutathione in muscle is increased by EA and MA.

The prognosis of patients with metastatic uveal melanoma is poor and there are limited therapeutic options. C-kit is expressed in the majority of patients with metastatic uveal melanoma. In this pilot trial, we examined the toxicity and efficacy of sunitinib malate, a multitarget tyrosine kinase inhibitor, in patients with metastatic uveal melanoma. Twenty patients with metastatic uveal melanoma expressing c-kit, 17 of whom failed previous treatments, were included in this study. Patients received sunitinib malate 37.5 mg daily continuously in 4-week cycles. The evaluation of response was carried out every 8 weeks. The overall survival (OS) and progression-free survival (PFS) were evaluated using Kaplan-Meier survival curves and differences in survivals were tested using the log-rank test. There was one partial response and 12 stable disease (SD) after sunitinib treatment. The median OS and PFS were 8.2 and 4.2 months, respectively. Three patients had SD for more than 12 months with sunitinib after failing previous treatments. The most common adverse events were fatigue (90%), diarrhea (60%), hemorrhage (55%), anorexia (45%), hand-foot syndrome (25%), hypothyroidism (25%), and rash (25%). Eleven patients required a dose reduction to 25 mg daily secondary to grade 3 adverse events. The degree of c-kit expression in melanoma cells was not associated with longer PFS or OS. Patients who developed systemic metastases after more than 5 years of their initial diagnosis had better PFS (median PFS: 5.8 vs. 2.6 months, P=0.005). Sunitinib was safely administered and showed potential clinical benefit in patients with metastatic uveal melanoma. The lack of a correlation between c-kit expression and clinical outcomes requires further investigation on the mechanism of sunitinib in metastatic uveal melanoma.
