A case of a 73-year-old woman with acute renal failure due to toxic shock syndrome (TSS) is reported. The patient was admitted to our hospital with the complaints of high fever, disturbance of consciousness and shock. Laboratory findings on admission were; CRP 25.11 mg/dl, WBC 35000/ microl, Plt 1.6 x 10(4)/ microl, GOT 155 U/l, GPT 65 U/l, CPK 4202 U/l (CPK-MM 96%), BUN 123 mg/dl and SCr 7.0 mg/dl. Because of anuria, hemodialysis was performed. This patient was treated with dopamine, methyl prednisolone (MP), frozen fresh plasma, AT III, antibiotics, and platelet transfusion. The bacterial cultures of blood and cerebrospinal fluid were negative, but MRSA was isolated subsequently from the pharynx and vagina. We investigated the production of toxic shock syndrome toxin 1 (TSST-1) and staphylococcal enterotoxins (SE). The isolated MRSA produced TSST-1, SEB and SEC. Accordingly, we made the diagnosis of TSS. After improvement of acute renal failure and the patient's general condition, MRSA persisted and TSST-1 was still found in the patient's blood. Finally we eradicated the MRSA and TSST-1 after administration of ciprofloxacin hydrochloride (CPFX) and Rifampicin (RFP).

Hyperlipidaemia of 18 male and 20 female patients following successful renal transplantation was treated with daily 20 mg fluvastatin (Lescol) for 12 weeks. The patients were several months after transplantation, and their total cholesterol levels exceeded 6.5 mmol/l following an 8-week diet. The effect of fluvastatin on the levels of total cholesterol, HDL, LDL, triglyceride, Apo A1 and Apo B, as well as of lipoprotein(a) was examined. Furthermore, changes of the renal function (GFR-urea, creatinine, uric acid) and hepatic function (bilirubin, GOT, GPT, CPK, ALP) were followed up, together with the body weight and blood pressure. The results of the examinations are summarized as follows: Fluvastatin may be administered effectively and without side effects in a daily dose of 20 mg in appropriately selected renal transplant patients. The average total cholesterol values, which were 7.91 mmol/l in men and 7.78 mmol/l in women following the diet, were reduced by 22-25% (p < 0.001) after 6 and 12 weeks, respectively, of fluvastatin treatment. The levels of LDL also decreased significantly (p < 0.001): in response to a 20 mg evening dosage, reduction of more than 25% was observed in 78% of men and 65% of women. Reductions of the Apo B levels were more pronounced in the females (18.3% men vs. 21.2% women). The ratio C/HDL-C decreased both in men (from 5.49 to 4.19) and in women (from 4.83 to 4.02). The ratio Apo B/Apo A1 also decreased (men: from 0.86 to 0.73, women: from 0.73 to 0.66). The concentrations of HDL and Apo A1 did not increase significantly, the reductions in the levels of triglyceride and lipoprotein(a) were not considerable either. An increase in the levels of hepatic enzymes and CPK was not encountered during the administration of fluvastatin. In two patients the levels of serum bilirubin increased by 2-4 micromol/l. Three patients complained about temporary myalgias of the sacroiliac or lumbar region which, however, were not accompanied by elevated CPK levels. The monitored levels of cyclosporine, urea and creatinine did not increase significantly during the 12 weeks of treatment. Two patients had temporary gastric complaints.

We have characterized clinical and diagnostic features in 18 cases of Legionella pneumonia. Age average of patients was 62.0 years old (male:female = 14:4) and underlying diseases were observed in 12 patients. Legionella pneumonia were diagnosed in 3, 5, 8 and 9 cases by culture, serum antibody measurement, urinary antigen detection and PCR, respectively. Sixteen cases were caused by L. pneumophila, while the other 2 cases were L. bozemanii pneumonia and L. pneumophila or L. dumoffii pneumonia. Chest X-rays of those patients showed multiple pneumonia shadows in 14 cases, alveolar shadows in 10 cases, pleural effusion in 5 cases. Blood-gas analysis on admission indicated hypoxemia in all cases with abnormal A-a DO2. Laboratory findings showed abnormal data in WBC, CRP, LDH, CPK and liver function tests (ex. GOT, GPT) in most cases. Serum antibody testing showed positive by 5 weeks after onset of pneumonia, but 10 cases of Legionella pneumonia diagnosed by other techniques were judged to be negative. In urinary antigen detection test, 6 and 2 cases showed positive 1 and 4 weeks after onset of pneumonia, respectively. Macrolide antibiotics were administered in all cases during the episode, but delay of macrolide administration was observed in 3 of 4 cases of dead outcome. Serum antibody measurement, urinary antigen detection and PCR, in addition to culture to bacteria, may be required for exact diagnosis of Legionella infection.

A 47-year-old woman visited a clinic with dyspnea which had continued for two months and was followed by general fatigue and fever. Antibiotics were not effective. Edematous erythema occurred on her face, elbows, knees and feet, and she entered our hospital. A skin biopsy revealed interface dermatitis with severe edema and mucinosis in dermis. Diffuse bilateral infiltration was observed in the chest X-ray, and laboratory findings showed increased LDH, GPT, GOT and CPK. No antinuclear factor was detected. Her respiratory condition rapidly worsened, and she died eight days after hospitalization in spite of corticosteroid pulse therapy. The autopsy revealed that the main cause of death was diffuse alveolar damage (DAD). Interstitial pneumonia related to dermatomyositis is not histologically uniform; the response to the therapy depends on its histological type. The patients with dermatomyositis who have poor prognosis are clinically characterized by acute onset with general symptoms and less pronounced muscle weakness; they generally show DAD in their lungs. We need to establish a simple method for distinguishing histological types of interstitial pneumonia and adequate therapy for each one.

DEHP [di-(2 ethyl hexyl) phthalate], a widely used plasticizer in blood storage bags, leaches out in appreciable amounts into blood (about 10 mg/100 ml) resulting in exposure of recipients of blood transfusion to this compound. Various reports indicate the toxicity of DEHP, particularly in liver and reproductive organs but all these studies used large doses (up to 2 g or more/Kg body weight) and oral route of administration which are not relevant to the intravenous administration during blood transfusion or the low amounts present in blood. We have studied changes in the activity of some important enzymes-gamma-GT, ALT, CPK, LDH, alkaline phosphatase, acid phosphatase, beta-glucuronidase and few other parameters like vitamin E, glutathione, serum albumin etc in rats administered low doses of DEHP (corresponding to transfusion of 2, 4, 6 and 10 units of blood). Histopathology of the organs has also been carried out. The results obtained indicate no serious toxic effects for DEHP at the level present in blood stored in DEHP plasticized blood bags as evidenced by the lack of any significant alteration in most of the biochemical parameters studied. Even in those cases where there was alteration (for e.g., decrease in the level of vitamin E) 24 hr after administration of DEHP, it returned to near normal level with in 72 hr to 7 days. No histopathological changes were observed in any of the organs at these levels of DEHP. It is concluded that DEHP did not cause any serious toxic effect even at doses corresponding to transfusion of several units of blood in a recipient.

This study was undertaken to assess our experience with the first 50 patients who underwent CABG without cardiopulmonary bypass. In seven patients left internal mammary artery to left anterior descending artery (LIMA-LAD) grafting was performed through a short left anterior thoracotomy. In 43 other patients median sternotomy was used. Primary CABG was performed in 48 patients; there were two reoperations. Eleven patients had unstable angina. Three patients had left ventricular ejection fraction (LVEF) equal to or lower than 25%. One patient had carcinoma of the right lung coexisting with unstable angina and underwent also right lower lobectomy. In each patient the clinical course, 12-lead ECG, transthoracic echocardiography and the serum levels of creatine kinase (CPK), alanine aminotransferase (ALAT), aspartate aminotransferase (AspAT) were assessed. The need for inotropic or intraaortic balloon counterpulsation (IABP) support and blood transfusion was also recorded. There were three deaths, all in the sternotomy group (6%). A patient with systemic lupus erythemetodes (SLE) died of postoperative MI due to graft thrombosis. Another patient who was found to have porcelain aorta and had LIMA-LAD grafting as a rescue procedure died of MI with low cardiac output. The third patient with unstable angina and ejection fraction of 30% developed postoperative MI with ventricular arrhythmia. One patient with LIMA-LAD graft in whom percutaneous translaminal coronary angioplasty (PTCA) had been abandoned because of coronary spasm developed acute myocardial ischaemia 5 h postoperatively. He had a vein graft placed to LAD in cardiopulmonary bypass, his further course was uneventful. Six patients had IABP support. Nine patients needed inotropic support. Ten patients received blood transfusion. Twelve-lead ECG did not show acute ischaemia or MI, apart from the above described cases. Echocardiographic check showed improved IVS contractility in three patients and better apex motion in one case. In the other survivors the echocardiographic findings were the same as before the procedure. ALAT and AspAT serum levels were normal in all the survivors, and the CPK levels did not exceed 200 IU/ml. One patient from the mini-thoracotomy group had recurrent angina 2 months after the procedure. His left internal mammary artery (LIMA) graft was occluded; we replaced it with a vein graft. All 47 survivors remain asymptomatic, with the mean follow-up time of 6 months. Coronary surgery without cardiopulmonary bypass seems a valuable alternative for high-risk patients.

The aim of the study was to estimate the usefulness of rest 99mTc-MIBI SPECT scintigraphy to evaluate carbon monoxide cardiotoxicity in acute group poisonings. There were 7 study patients (5 men and 2 women) aged from 14 to 35 years treated at the Department of Clinical Toxicology intoxicated with CO at three different sites: three persons were intoxicated at one, two persons at the second and the next two persons at another site of exposure. As derived from interview the circumstances, source and duration of exposure were similar within the separate group. This enables a comparison of clinical course of carbon monoxide poisoning, particularly the circulatory system of people who were simultaneously exposed to the same source of carbon monoxide. Measurement of COHb, blood lactate level, duration of exposure and ECG examination were performed on admission to the Clinic. The enzymes activity (ALT, AST, CPK) were evaluated after 24 hours. The rest 99mTc-MIBI SPECT scintigraphy was performed in all patients two to five days after intoxication. The changes in myocardial scans were graded according to the arbitrarily accepted point scale. Considering the results of ECG and enzymes activity only, no objective were found to diagnose the cardiac dysfunction. However the perfusion scintigraphy scans indicated regions of myocardium that have decreased blood flow in all the study patients.

Previous work has shown, that stobadine-hydrochloride (-)cis-2,8-dimethyl-2,3,4,4a,5,9b-hexahydro-14-pyrido(4,3b) indole administered in a single dose 2 mg/kg of body weight reduces cardiotoxic effect of isoproterenol (1 mg/kg) as shown by lowered serum enzyme activities of AST, CPK, LDH and ALT. We studied the effect of stobadine in vivo on respiration, the level of ATP, malondialdehyde (MDA) and superoxiddismutase (SOD) in heart mitochondria. Serum enzyme activities of AST, CPK and LDH after stobadine application were significantly decreased. In mitochondria, respiration and activity of SOD were inhibited, level of MDA was increased and level of ATP was unchanged. The cardioprotective effect of stobadine is not linked to preservation of mitochondrial function. This effect is probably more complex and mediated on the level of the whole organism.

1,1,1,3,3-Pentafluoropropane (HFC 245fa) is a volatile, low boiling liquid. It was inactive in a reverse mutation (Ames) assay using five strains of Salmonella typhimurium and one strain of Escherichia coli. It was also inactive in an in vivo mouse micronucleus assay with exposures of 101,000 ppm. In a chromosome aberration study with human lymphocytes, some activity was seen when cell cultures were exposed to atmospheres of 30% v/v or higher for 24 h without metabolic activation. No activity was seen in assays using less than 30% v/v or exposure times of less than 24 h. No activity was seen in the presence of metabolic activation even with exposures of 70%. It was not toxic by the dermal route. There was no mortality or significant signs of toxicity when rats and mice were given 4- h exposures to levels of 203,000 ppm or 101,000 ppm of HFC 245fa, respectively. In a cardiac sensitization study with dogs involving intravenous administration of epinephrine, the no observed effect level (NOEL) was 34,000 ppm and the threshold for a response was 44,000 ppm. In a rat inhalation, developmental toxicity study, a slight reduction in pup weight was seen at 50,000 ppm, but not at 10,000 ppm. There were no developmental effects at any level. A series of three inhalation toxicity studies were conducted. All involved daily 6-h exposures up to 50,000 ppm. The first study involved 14 consecutive snout-only exposures. There were no treatment-related effects on body weight, survival, or histologic parameters. BUN, GPT, and GOT levels frequently were elevated compared to controls , whereas cholesterol levels tended to be lower. The second study involved 28 consecutive whole-body exposures. Again, there were no treatment related effects on body weight, survival, or histological parameters. Urine volume was increased. Increases were also seen in several red blood cell parameters. These may be related to partial dehydration. Increases were seen in BUN levels and alkaline phosphatase (AP), GPT, GOT and CPK activities, primarily in rats exposed at 10,000 and 50,000 ppm. Urinary fluoride levels were also elevated in an exposure- related pattern. In the third study, whole-body exposures were conducted 5 days per week for 13 weeks. There were no treatment-related effects on survival, clinical observations, body weight gain, or food consumption. Urine volumes were increased, urinary fluoride levels were elevated, and increases were seen in red blood cell counts, and related parameters and increases were seen in AP, GOT, GPT and CPK activities. These effects were seen in the 10,000 and 50,000 ppm exposure level groups. Histopathologic examination did not show any effects on the kidney, liver, or lungs. There was an increased incidence of myocarditis in all animals exposed at 50,000 ppm and the majority exposed at 10,000 ppm. It was described as mild. Based on these findings, 2000 ppm appears to be a no observed adverse effect level.
