Ten subjects were exposed to high-G on the human centrifuge using seatback angles of 13 degrees, 30 degrees, 45 degrees, 60 degrees, and 75 degrees from the vertical, and body configurations of the lower portion of the body with pelvis and legs elevated, pelvis, elevated, and pelvis elevated with knees on chest (fetal position). Tolerance was measured by peripheral light loss. Mental status, respirations, core and ambient temperatures, and ECG were monitored. Daily physio-chemical data included: creatinine, bilirubin, phosphorus, alkaline phosphatase, uric acid, cholesterol, total protein, albumin, BUN, glucose, LDH cardiac isoenzyme No. 5, SGOT, SGPT, CPK, CBC, and urinalysis. Tiredness, pressure on the chest, and general discomfort in the fetal position were reported. Physical examination demonstrated petechiae. Heart rate, respiratory rate, and temperature increased post-session. There was a significant rise in values for albumin, chloride ion, creatinine, calcium, LDH, BUN, and immature white cells; and a decrease in values for phosphorus, SGOT, SGPT, protein, uric acid CO2, globulin, hematocrit, monocytes, and eosinophils.

A 51-year-old female with systemic lupus erythematosus (SLE) was admitted in November 1987 because of general fatigue and muscular weakness. She was treated with prednisolone (PSL) 30 mg and azathioprine (AZP) 50 mg after failure in the management of thrombocytopenia by PSL 15 mg. She exhibited no splenomegaly. Muscular atrophy and weakness were seen in the proximal muscles. Her platelet count was 44,000/microliters. A bone marrow aspiration revealed an increase in megakaryocytes. The blood chemistry revealed a normal CPK level and an elevated LDH level, indicating a presence of steroid myopathy. A splenectomy was performed after an increase of platelet count by giving gamma-globulin 400 mg/kg for 5 days. The platelet count rose to 368,000/microliters on the 46th postoperative day. She was treated with PSL 5 mg and AZP 50 mg as postsplenectomy therapy. The splenectomy did not adversely affect other aspects of SLE, in particular, renal function. She had no major complications in the postoperative period. Her platelet count reached a plateau 4 months later and revealed 115,000/microliters 18 months postoperatively.

Overwork weakness has been reported in survivors of poliomyelitis with residual paralysis. Investigators have recently reported that approximately 25% of polio survivors experience functional declines with onset of symptoms of new weakness, fatigue, and muscle pain. The diagnosis of overwork weakness has remained a clinical diagnosis, as previous investigations have failed to uncover reliable, objective, diagnostic methods to confirm the diagnosis in symptomatic individuals. A case is presented in which markedly elevated levels of CPK were present with symptoms of weakness, fatigue, and muscle pain. These levels declined after clinical intervention, with resolution of symptoms. This case represents an overuse syndrome in which muscle fibers were being damaged through overuse. This case further suggests the possible role of serum CPK in the diagnosis of, and in monitoring clinical intervention in, some polio survivors who experience overwork weakness.

Our understanding of the time course of recovery from exertional heatstroke (EH) and the heat acclimation ability of prior EH patients is limited. This manuscript reviews previous findings regarding recovery from EH and presents original research involving the heat acclimation ability of 10 prior EH patients (PH) and 5 control subjects. Heat acclimation, by definition, distinguishes heat-intolerant from heat-tolerant prior heatstroke patients. Nine PH exhibited normal heat acclimation adaptations (40.1 degrees C, 7 d, 90 min.d-1), thermoregulation, sweat gland function, whole-body sodium and potassium balance, and blood values at 61 +/- 7 d after EH. One PH (subject A) did not adapt to exercise in the heat, was defined heat intolerant, but subsequently was declared heat tolerant (11.5 months post-EH). Three PH exhibited large, unexpected increases in serum CPK levels, which resolved upon subsequent testing, and were probably related to their detrained state and the exercise which they performed. It was concluded that: 1) sleep loss and generalized fatigue were the most common predisposing factors for PH; 2) recovery from EH was idiosyncratic and may require up to 1 year in severe cases; 3) PH were not hereditarily heat intolerant, prior to EH; 4) no measured variable predicted recovery from EH, or heat acclimation responses; 5) heat intolerance occurs in a small percentage of prior heatstroke patients, and may be transient or persistent.

A 37-year-old man suffered from photosensitivity and urinary casts with serological findings of positive anti-DNA antibody, LE cells and false positive VD reaction in September of 1979. He developed general fatigue, dyspnea and diplopia with ptosis of bilateral eyelids in November of 1979, which were improved by the anti-cholinesterase drugs. In January of 1980, he had an attack of unconsciousness and his chest X-ray film showed several tumorous shadows in the anterior mediastinum and middle and lower lung fields. Treating him with chemotherapy of VEMP, the pulmonary shadows disappeared. However, he developed severe muscle weakness with an elevated CPK (430 mU/ml) and a myogenic EMG pattern along with an increased anti-acetylcholine receptor antibody (243 n Mol/l), dysphagia and eyelid-ptosis. He died in September of 1985 and his autopsy disclosed a malignant thymoma of mixed type in the anterior mediastinum and an atrophy and fibrosis with infiltration of inflammatory cells in the striated muscles.

Nine semi-professional football players have been studied during a pre-championship retreat in a hilly area with their team. The nine athletes drank "Amorosa" oligo mineral water for three weeks and various haematochemical parameters (such as uricaemia, creatinemia, azotemia, sodium content) both before and after the retreat, have been evaluated. Furthermore, LDH and CPK were monitored before and after an exertion test on an exercise bicycle after hydropinic ingestion. The results obtained fully confirm the diuretic and cathartic properties of the water and its property of mobilization of hydroelectrolytic system which are even more useful in subjects needing a rapid elimination of metabolic wastes accumulated during muscle fatigue.

Five subjects wearing standard USAF anti-G suits and seated at a 65 degrees back angle were exposed to a simulated aerial combat maneuver (SACM) which was repeated 5 times with 4-min 1-G rests between each SACM exposure. The SACM was 122 s in duration with 10 s acceleration peaks of 10, 8, and 6 G; between these peaks, the subject was at 4 G for 15 s. This series of repeated SACM exposure fatigued four of the five subjects. Heart rate and rhythm, arterial oxygen saturation, expired gases, lactate, pyruvate, glucose, CPK enzymes and isoenzymes, blood volume, subjective fatigue measurements, and subject performance were examined relative to the development of fatigue, the energy cost of the M-1, and tolerance to the SACM. All physiologic-metabolic parameters were significantly affected by the repeated SACMs. However, only heart rate changes appeared to be correlated with developing fatigue. A significant amount of energy is required to perform the M-1. Subjects whose energy-metabolic and cardiovascular states are least disturbed by high G exposure are those persons who will perform best and become least fatigued during repeated aerial combat maneuvers.

Toxic manifestations of digitalis are one of the most prevalent adverse drug reactions encountered in clinical practice. The estimated incidence is about 20% in hospitalized patients in the USA. The authors describe a rare case of myocardial "catecholamine necrosis" (anteroseptal myocardial infarction) during accidental digitalis intoxication. A male patient, 75 years old, suffering from cirrhosis and ascites, take on by mistake a tablet of digoxin 0.25 mg. four times at day for eleven days. He hadn't heart disease in the past. At the eleventh day the patient showed a deep tiredness and so he was submitted to a clinical examination and electrocardiogram. The ECG demonstrated an anteroseptal myocardial infarction in the second-third electrical stage. The patient was hospitalized. The successive examination revealed: very high plasma digitalis concentrations; an increase of the serum levels of CPK and LDH; a significant increase of plasmatic and urinary catecholamine levels which return to normal values after fifteen days; apical akinesia at the echocardiographic examination; no signs of residual myocardial ischemia to the echo-dypiridamole stress test; normal coronary artery to the coronary arteriography and absence of coronary artery spasm to the ergonovine test. Furthermore the abdominal echography and the abdominal computerized tomography didn't reveal surrenal disease but showed an important liver disease. The patient was free from other cardiac events in the follow-up. Generally, during the digitalis intoxication we observe various rhythm and conduction disturbances. Instead in this case no serious arrhythmias were registered and the main expression of the drug toxicity was an anteroseptal myocardial infarction with undamaged coronary artery. Also the usual extracardiac symptoms and signs of the digitalis intoxication were absent in this case. All these observations can be explained with the pathological increase of the cathecholamine levels, indirectly induced by digitalis; with the direct toxic effect of the drug at the myocardic level; with the contemporary absence of ionic disturbances; with the concomitant liver disease. The direct toxic effect of the digitalis produced an increase in calcium ions availability for the electromechanical coupling and an increase of the intramyocardial pressure; the increase of the adrenergic activity determined contemporary an increase in the oxygen consumption of the myocardial cells, a rise of vascular tone and coronary artery tone and a reduction of the duration of the diastole. All these factors provoked a "primary and secondary" ischemia which evolved toward a real "cathecholamine necrosis" and produced a myocardial infarction. This hypothesis explains the myocardial infarction in absence of injury at the coronary arteriography and without coronary spasm at the ergonovine test; moreover it explains the transient increase in cathecholamine plasma levels observed in the acute phases an normalized after fifteen days. The "cathecholamine necrosis" is an anatomical definition, nevertheless in our opinion it gives account of the rare clinical situation observed.

A 51-year-old female was admitted with complaints of fever and general fatigue. Chest X-ray showed diffuse bilateral fine nodular shadows and infiltrates. Complication of hepatic and muscular injury was suspected from increased levels of GOT, GPT and CPK in the serum. Arterial blood gas analysis revealed hypoxemia. Because hypoxemia aggravated despite treatment with intravenous minocycline (200 mg/day), corticosteroids and mechanical ventilation were started, and the administration of minocycline (400 mg/day) and sparfloxacin was added. Consequent, chest X-rays and several laboratory data improved gradually. The final diagnosis was established with a significant rise of both IgG and IgM antibody against Chlamydia psittaci with MIF and identification of Chlamydia with the cell culture method. Chlamydia was successfully isolated from BALF of this patient obtained 5 days after commencement of minocycline treatment. Psittacosis should be considered as a possible cause of severe respiratory failure necessitating emergency care including mechanical ventilation.

A 60-year-old male was admitted to our hospital complaining abdominal pain and fatigue. Complete blood count showed as follows; WBC 3,900/microliters (48% of monocytes), Hb 11.5 g/dl, Plt 0.9 x 10(4)/microliters. Marrow smears showed the presence of phagocytic histiocytes that consist 22.4% of total nuclear cells. Laboratory findings showed as follows; BUN 109.5 mg/dl, Creatinine 7.4 mg/dl, CPK 1,259 IU/l, Aldolase 195 IU/l, Myoglobin 4,200 mg/dl. Serological studies showed a 16-fold increase in herpes-simplex virus (HSV) antibody titers 4 weeks after admission. So we diagnosed his illness as virus-associated hemophagocytic syndrome (VAHS) and rhabdomyolysis that were associated with HSV. We performed three times of hemodialysis for acute renal failure and used prednisolone for VAHS. These treatments were successful, and he made a complete recovery from illness. VAHS complicated by rhabdomyolysis is very rare, and we think this case is full of suggestions.
