This review summarizes the symptoms, signs and laboratory abnormalities seen in 59 patients with chronic fatigue syndrome (CFS), 2 patients with post-infectious CFS and in 26 patients with possible CFS whose illnesses fulfill the criteria proposed by the study group of the Ministry of Welfare, Japan. The characteristic symptoms and signs of CFS are prolonged generalized fatigue following exercise, headache, neuropsychological symptoms, sleep disturbance and mild fever. In possible CFS patients, the frequency of mild fever, muscle weakness, myalgia and headache is low. Our standard hematologic and laboratory tests revealed a few abnormality in patients with CFS. The characteristic abnormality in CFS patients is the low values of 17-Ketosteroid-Sulfates/creatinine in morning urine and the acylcarnitine deficiency. It seems likely that this deficiency of acylcarnitine induces an energy deficit in the skeletal muscle, resulting in general fatigue, myalgia, muscle weakness and postexertional malaise in CFS patients. Virologic studies revealed no evidence of retrovirus infection with HTLV-1, HTLV-2 and HIV, but the reactivation of HHV-6 infection was apparent.

This multi-center trial was carried out to assess the therapeutic potential of recombinant tumor necrosis factor (rTNF) as the first form of systemic therapy for advanced carcinomas of gastric and pancreatic origin. To be eligible patients were required to have no overt sign of coagulopathy and hepatic function studies with enzymes less than two times beyond the normal range. Twenty nine patients with gastric cancer and 26 with pancreatic cancer were entered from various institutions in the Southwest Oncology Group with 27 and 22, respectively, meeting eligibility criteria. Drug treatment consisted of rTNF (Genentech) given at a dose of 150 micrograms intravenously for five consecutive days every 3 weeks; 50% dose reduction was made for acute intolerance such as hypotension or severe fever and chills. Although eight patients with gastric cancer and five patients with pancreatic cancer received four or more courses of treatment, no objective antitumor responses were recorded. As in other trials common toxicities of rTNF included nausea and vomiting, chills and fever, hypotension, headache, myalgias, fatigue and malaise. However, in this trial, other toxicities became prominent: four episodes of symptomatic disseminated intravascular clotting occurred among patients with pancreatic cancer. Eleven with this disease and five with gastric cancer manifested laboratory findings of abnormal amounts of fibrin split products, and/or hypofibrinogenemia, and/or thrombocytopenia after treatment began. Other laboratory abnormalities that were commonly encountered included hyperglycemia, hypertriglyceridemia, anemia, neutropenia and an elevation in liver enzymes. We conclude that rTNF does not demonstrate antitumor efficacy against adenocarcinomas of the stomach and the pancreas.(ABSTRACT TRUNCATED AT 250 WORDS)

Ray Kennedy's Parkinson's disease probably began during his distinguished career as a professional soccer player at least 10 years before the first unequivocal physical signs and 14 years before the diagnosis was finally made, when he was 35-years old. Early prodromal symptoms included intermittent subtle disturbances of movement and posture affecting the right arm and leg, mild facial immobility, episodes of profound malaise and lack of energy, inner feelings of tremulousness, excessive unprovoked bouts of perspiration, and accompanying feelings of heat. Abnormalities of movement in the right arm can be seen in video footage of soccer games up to 8 years before his disability came to medical attention. Many of his premorbid personality traits are characteristic of those believed to be associated with the subsequent development of the malady. At least in some patients with Parkinson's disease, the search for instigating aetiological factors should focus 10-20 years before the cardinal signs can be recognised with certainty.

The optimal schedule for recombinant interleukin-2 (rIL-2) administration is unclear. Because the clinical and immunological effects of prolonged continuous exposure to rIL-2 are unknown, we have conducted a phase I study to assess the toxicity and feasibility of continuous low dose infusion of rIL-2 (EuroCetus) using central venous access with a portable infusion device on an out-patient basis. Twenty-two patients entered the study, 13 with melanoma and nine with renal cell cancer, age range 26-66 years (median 51), performance status less than or equal to 1. They were treated with one of the following doses per m2 per 24 h: 0.18 x 10(6) IU, 0.6 x 10(6) IU, 1.8 x 10(6) IU, 3 x 10(6) IU, 6 x 10(6) IU and 9 x 10(6) IU. Toxicity was evaluable in 20 patients receiving greater than or equal to 3 weeks treatment duration or in whom treatment was discontinued prematurely because of toxicity. Constitutional symptoms consisting of fatigue, malaise and fever up to 40 degrees C without significant organ dysfunction occurred with doses greater than or equal to 1.8 x 10(6) IU m-2. The maximum tolerated dose was 6 x 10(6) IU m-2 24 h-1. In all patients toxicity reached a peak at 3 weeks and resolved thereafter despite continued rIL-2 treatment. Peripheral blood eosinophilia (up to 66% of white blood cell count) followed the same pattern. An infection of the central venous access occurred in 55% of the patients but this was mostly asymptomatic. Thirteen patients were treated greater than or equal to 6 weeks and were evaluable for tumour response. A partial remission occurred in a patient with melanoma with a dose of 1.8 x 10(6) IU rIL-2 m-2 24 h-1.

During 24 months in an uncontrolled, retrospective study of 268 patients with cat-scratch disease (CSD), 202 were treated with 18 different antimicrobial agents. Criteria for antibiotic effectiveness were established. One or two antibiotics were taken separately for at least 3 to 5 days by 202 patients with CSD. Outcome was determined by follow-up examinations and telephone. Effectiveness of antibiotic therapy was based upon 3 or more days of therapy and clinical improvement of the patient with absence of and/or a decrease in malaise, fatigue, fever, headache, anorexia, lymphadenopathy and, in 90 patients, a declining or normal sedimentation rate. Of 18 different antimicrobials prescribed, 14 commonly used antibiotics were judged to be of little or no value in treatment of CSD. Four antimicrobials were efficacious. Efficacy of the three oral drugs in decreasing order was: rifampin 87%, ciprofloxacin 84%, trimethoprim-sulfamethoxazole 58%. Gentamicin sulfate intramuscular was 73% effective. Antibiotic therapy can be considered for patients with severe cat scratch disease. Conservative, symptomatic treatment is recommended for the majority of patients with mild or moderate CSD.

Cryptogenic organizing pneumonitis is a clinical and pathologic syndrome characterized by a "pneumonia-like" illness with excessive proliferation of granulation tissue within small airways and alveolar ducts associated with chronic inflammation in the surrounding alveoli. The duration of illness prior to lung biopsy is short, usually less than 2 months, and it is markedly different from that of IPF. Interestingly, unlike in IPF where the patient has difficulty remembering the exact onset of symptoms, patients with COP are frequently very specific about the timing of their disease onset. This is because the disease onset is recent and is often dramatic with the development of a severe flulike illness, ie, cough, fever, malaise, fatigue, and weight loss. Inspiratory crackles are frequently present on chest examination. Pulmonary function is usually impaired with a restrictive defect being most common. Gas exchange abnormalities are extremely common with a reduction in Dco and resting hypoxemia being almost universal findings. The roentgenographic manifestations are quite distinctive with a pattern of bilateral, diffuse but inhomogeneous, ground-glass or alveolar opacities being present in the majority of the cases. Bronchoalveolar lavage findings are nonspecific but usually reveal a lymphocytosis. The response to corticosteroid treatment is quite favorable and death from progressive disease is uncommon in COP, especially if treatment is instituted early in the course of the disease. In our experience, the cases with the worse prognosis are those associated with another disease process, in particular, connective tissue disorders like rheumatoid arthritis. In fact, these patients are prone to develop a rapidly progressive form of BOOP with a clinical course similar to the "Hamman-Rich syndrome." Recurrences are relatively frequent, consequently, withdrawal of treatment should be done with extreme caution. Corticosteroids have been the conventional initial treatment of COP, although to our knowledge, there are no controlled clinical trials to support it use. Antibiotics are not effective in treating this syndrome. Thus, based solely on our experience and that of others, we believe that high-dose corticosteroid therapy should be used to treat COP, usually initiated with 1 to 1.5 mg/kg/day (using ideal body weight) not to exceed 100 mg/day. Prednisone is given as a single oral dose in the morning. We recommended maintaining this dose for 4 to 8 weeks. If the patient's condition is stable or improved, the prednisone dosage is gradually tapered to 0.5 to 1 mg/kg/day (using ideal body weight) for the ensuing 4 to 6 weeks.(ABSTRACT TRUNCATED AT 400 WORDS)

Three siblings with inhaled elemental mercury toxicity are described, and the signs and symptoms of mercury toxicity, interpretation of mercury concentrations, and management of elemental mercury exposure are reviewed. A 4-year-old girl was admitted to the hospital with a history of fever and increasing irritability, fatigue, malaise, insomnia, headache, anorexia, and ataxia. She was discharged two days later with a diagnosis of acute cerebellar ataxia. During the following 18 days, the child's condition worsened, and she was rehospitalized. Meanwhile her 11-year-old sister was hospitalized for evaluation of fatigue, weakness, lower back pain, and ataxia. The older girl's blood mercury concentration, at 5.5 micrograms/dL, was in the toxic range. Twenty-four-hour urine mercury screening confirmed mercury intoxication in both children. Questioning revealed that the girls' brother had recently spilled 0.5-1 oz of elemental mercury in the house. All family members underwent blood and urine mercury testing. The brother underwent a dimercaprol challenge to determine his tissue mercury burden, which was found to be greater than 2.4 micrograms/dL. The sisters underwent two courses of chelation therapy with dimercaprol. Symptoms persisted in all three children, and they underwent five 10-day cycles of N-acetyl-D,L-penicillamine (NAP) therapy; the youngest underwent a third dimercaprol regimen. All siblings continued NAP chelation therapy because of extensive tissue mercury burden until the results of repeated urine mercury concentration determinations were normal.(ABSTRACT TRUNCATED AT 250 WORDS)

The efficacy and safety of oral sumatriptan as a 100-mg dispersible tablet was compared with oral Cafergot (2 mg ergotamine tartrate, 200 mg caffeine) in a multicentre, randomized, double-blind, double-dummy, parallel-group trial. In the trial, 580 patients were treated from 47 investigating centres in nine European countries. Sumatriptan was significantly more effective than Cafergot at reducing the intensity of headache from severe or moderate to mild or none; 66% (145/220) of those treated with sumatriptan improved in this way by 2 h, compared with 48% (118/246) of those treated with Cafergot (p less than 0.001). The onset of headache resolution was more rapid with sumatriptan, whereas recurrence of migraine headache within 48 h was lower with Cafergot. Sumatriptan was also significantly more effective at reducing the incidence of nausea (p less than 0.001), vomiting (p less than 0.01) and photophobia/phonophobia (p less than 0.001) 2 h after treatment, and fewer patients on sumatriptan (24%) than on Cafergot (44%, p less than 0.001) required other medication after 2 h. The overall incidence of patients reporting adverse events was 45% after sumatriptan and 39% after Cafergot; the difference was not significant. The most commonly reported events in the sumatriptan-treated patients were malaise or fatigue and bad taste; these were generally mild and transient. Nausea and/or vomiting, abdominal discomfort, and dizziness or vertigo were reported by a greater proportion of Cafergot-treated patients. It is concluded that oral sumatriptan was well tolerated and is a more effective acute treatment for migraine than Cafergot.

Safety information was pooled from 4,859 patients, mainly treated in controlled clinical trials with a dispersible tablet of sumatriptan or by a subcutaneous injection, and from 1,164 patients who received placebo by these routes. Safety monitoring involved collection of all adverse events, regardless of their relationship to treatment, and included routine laboratory screening tests and some special investigations. Individuals experienced several groups of symptoms that might be considered to be features of migraine itself or of the post-migraine period or due to treatment. The commonest complaints were an unpleasant taste or pain on injection. After oral sumatriptan (100-300 mg), some events (nausea, malaise) were characteristic of migraine and others (fatigue, sedation, weakness) were characteristic of the recovery period. With subcutaneous sumatriptan (4-8 mg) similar events were observed, but certain distinctive symptoms variously described as heaviness, pressure sensation, tingling, feelings of heat or warmth, were more common and affected various parts of the body. Their early onset and transient nature suggests some pharmacological mechanism, as yet not identified. Despite the mixed picture of symptoms recorded after treatment, they were not serious, they were transient and they were accepted by patients. Close patient monitoring allowed detailed evaluation of any possible cardiovascular side-effects as seen with other anti-migraine agents, particularly ergotamine. The evidence is reassuring but, since experience in patients with symptomatic ischaemic heart disease is limited, it is recommended that they should initially be treated with sumatriptan under medical supervision for their first two or three attacks.(ABSTRACT TRUNCATED AT 250 WORDS)

Pyridostigmine bromide, a reversible inhibitor of acetylcholinesterase (AChE), is effectively used as a pre-treatment to organophosphate intoxication. Previous studies have shown that an oral dose of 30 mg twice a day produces a sufficient inhibition of the enzyme activity (20-40%) without causing any significant adverse effect. During the Persian Gulf war pyridostigmine was taken for the first time under a chemical warfare threat. We searched for symptoms and complaints that may be related to the medication. Our survey included 213 soldiers who completed a questionnaire regarding possible symptoms and their severity. AChE inhibition level was compared between groups of soldiers with and without complaints. The most frequent symptoms were nonspecific and included dry mouth, general malaise, fatigue and weakness. Typical effects, such as nausea, abdominal pain, frequent urination and rhinorrhea, were infrequent. The severity of the symptoms was generally mild. The symptoms appeared around 1.6 h after taking the medication and recurred after each intake. No correlation was found between levels of cholinesterase and type or severity of complaints. Anxiety, which accompanies wartime, may have contributed to the appearance of significant symptoms. Further investigations concerning the effects of pyridostigmine ingestion under stressful conditions are warranted.
