Diaziquone (AZQ), a synthetic quinone with demonstrated activity against acute nonlymphocytic leukemia (ANLL), primary CNS tumors, and non-Hodgkin's lymphoma (NHL), is virtually devoid of nonhematopoietic toxicity at conventional doses. As a prelude to its inclusion into bone marrow transplant (BMT) preparative regimens, a phase I study of high-dose AZQ with autologous BMT (ABMT) was performed. Patients with refractory solid tumors and lymphomas were treated with a single 24-hour infusion of AZQ at 50 to 355 mg/m2 in dose escalations of 20%. Fifty-six patients received 69 courses. Those receiving greater than 60 mg/m2 had nadir granulocyte and platelet counts less than 500/microL and 20,000/microL, respectively. Nausea, vomiting, stomatitis, and diarrhea were mild, transient, and not dose-related. Transient minimal elevations of liver function tests were seen in five patients and were also not dose-related. The maximally tolerated dose (MTD) of high-dose AZQ was found to be 245 mg/m2, with nephrotoxicity being dose-limiting. Significant azotemia was seen in four of 12 patients treated at 295 and 355 mg/m2, including fatal anuric renal failure in three of these patients. Reversible proteinuria also occurred in 24 of 26 courses above 150 mg/m2, including nephrotic range proteinuria in eight courses, all at doses of 205 to 355 mg/m2. The proteinuria was also associated with multiple proximal tubular defects including generalized aminoaciduria and proximal renal tubular acidosis. There were six early deaths including two of early renal failure (295 and 355 mg/m2), two of sepsis (205 and 245 mg/m2), one of a pulmonary embolus (85 mg/m2), and one of progressive disease (60 mg/m2). Of 50 patients who were assessable for response, there were seven responses including two of 10 with primary CNS tumors, one of 12 with malignant melanoma, one of five with non-small-cell lung carcinoma, two of two with breast carcinoma, and one of one with ovarian carcinoma. Because of its activity in ANLL and NHL and its unique toxicity spectrum, high-dose AZQ may improve the efficacy of current BMT preparative regimens without significantly increasing their nonhematopoietic toxicity.

Pancreatic endocrine tumors are uncommon; of this type of tumors, the Verner-Morrison's syndrome, WDHA or vipoma is diagnosed very rarely. The present paper is a report of a pancreatic vipoma in a 60 year-old female; she presented with watery diarrhea, facial flushing, hypokalemia, hypochlorhydria, metabolic acidosis and reversible renal failure; these are the usual manifestations of the syndrome. The diagnosis was made on the basis of radiological imaging, CAT and arteriography as well as the finding or elevated levels of vasoactive intestinal peptide (VIP). The surgical resection of the tumor was followed by the remission of the symptoms and normalization of the plasmatic levels of VIP. It is necessary to recognize this type of tumors because the only way to achieve a curative surgical resection is after an early diagnosis.

We describe two female patients presenting with spontaneous peritonitis and fulminant Streptococcus pyogenes (Strep. pyogenes) septicemia and shock. Both patients recovered completely upon immediate antibiotic therapy, initially with broad range combination therapy effective against Strep. pyogenes, which was switched to penicillin G when culture results became available. This isolated strain in case 1 was M-type 28, which is the M-type most often isolated from vaginal swabs (as commensal) and from blood from patients with puerperal sepsis. Patient 1 had signs and symptoms of a toxic shock-like syndrome, including rapid onset of fever and shock, skin rash, desquamation of palms and soles, and multisystem involvement with vomiting, diarrhea, myalgia, renal failure, and severe disorientation without focal neurological deficits.

Toxic shock syndrome (TSS) is an acute febrile, exanthematous illness associated with multisystem failure including shock, renal failure, myocardial failure and adult respiratory distress syndrome (ARDS). It usually presents with fever, pharyngitis, diarrhoea, vomiting, myalgia, and a scarlet fever-like rash, and may progress rapidly (within hours) to signs of hypovolaemic hypotension such as orthostatic dizziness or fainting. The signs and symptoms of toxic shock syndrome should be recognised early to permit successful therapy. Patients are usually suffering from hypovolaemia due to leaky capillaries and fluid loss into the interstitial space, and consequently large volumes of fluid, both crystalloid (e.g. saline, electrolyte-solutions) and colloid (e.g. albumin, intravenous gamma-globulin), may be necessary to maintain adequate venous return and cardiac output. Patients with toxic shock syndrome usually have a focus of staphylococcal infection such as a surgical wound infection or soft tissue abscess, or they may have TSS associated with menstruation and use of a vaginal device such as tampons. The site of infection should be adequately drained and treated with antimicrobial therapy. Subacute complications including ARDS and myocardial failure require a thorough understanding of the underlying pathophysiology to ensure appropriate treatment. Recurrences of TSS can be avoided by appropriate antimicrobial treatment and avoidance of recurrent conditions which might favour staphylococcal toxin production (e.g. use of tampons during menstruation). More than 95% of patients survive toxic shock syndrome if appropriate therapy is instituted early.

Horses suffering from trauma, sepsis, and severe burns need 12% to 16% of protein (dry matter basis) in their diet. Since reduced appetite may be a problem, relatively energy dense (greater than 2 Mcal DE/kg) feeds should be offered. In hepatic failure, maintenance protein requirements (8% on a dry matter basis for adult horses) should be met with feeds that are high in short branched-chain amino acids and arginine but low in aromatic amino acids and tryptophan (for example, milo, corn, soybean, or linseed meal) in addition to grass hay. Vitamins A, C, and E should also be supplemented. In cases with renal failure, protein, calcium, and phosphorus should be restricted to maintenance or lower levels. Grass hay and corn are the best feeds for horses with reduced renal function. Do not offer free-choice salt to horses with dependent edema from uncompensated chronic heart failure. Following gastrointestinal resection, legume hay and grain mixtures are the feeds of choice. Horses with diarrhea should not be deprived or oral or enteral alimentation for prolonged periods of time. Liquid formulas may be used if bulk or gastrointestinal motility are a problem. Apple cider vinegar and a high grain diet may reduce the incidence of enteroliths in horses prone to this problem. Pelleted feeds will reduce fecal volume and produce softer feces for horses that have had rectovaginal lacerations or surgery. Horses with small intestinal dysfunction or resection should be offered low residue diets initially, but long-term maintenance requires diets that promote large intestinal digestion (alfalfa hay, vegetable oil, restricted grain). Geriatric horses (greater than 20 years old need diets similar to those recommended for horses 6 to 18 months old.

The prognosis for diabetics with autonomic neuropathy is little known. We therefore studied the progress of young insulin-dependent diabetics, first identified as having abnormal autonomic function 10-15 years ago. We have shown that the mortality of diabetics with symptomatic autonomic neuropathy is increased, but is less than previously reported. Mortality in asymptomatic diabetics with an isolated abnormality in autonomic function tests is not increased. The heart rate variability declines at 1.02 +/- 0.47 (SD) per annum in diabetics with an initially normal heart rate variability. While symptoms of autonomic neuropathy do not usually remit even over a decade, they do not commonly progress. Three groups of young insulin-dependent diabetics had heart rate variability tested between 1972 and 1977 and have been reviewed 10-15 years later. Group A (n = 49) had symptomatic autonomic neuropathy and an abnormal heart rate variability (less than 12), Group B (n = 24) were asymptomatic yet had an abnormal heart rate variability and Group C (n = 38) were asymptomatic and had a normal heart rate variability (16-26). The 10-year survival in Group A (73.4 per cent) was less (P less than 0.05) than in Groups B (91.7 per cent) or C (89.5 per cent) which did not differ from each other. The 18 Group A deaths were due predominantly to renal failure (n = 4), myocardial infarction in patients with nephropathy (n = 3) and sudden unexpected death (n = 3). The chief symptoms of autonomic neuropathy--diarrhoea, postural hypotension and gustatory sweating, were very persistent but did not necessarily deteriorate or become disabling in the majority of patients. The development of autonomic symptoms in asymptomatic patients with abnormal heart rate variability was uncommon over a decade.

We studied a group of 48 patients with systemic amyloidosis and end-stage renal disease (ESRD) treated with chronic dialysis to analyze the clinical course and the factors which can influence survival. This group was compared to a control group of 63 nondiabetic patients without amyloidosis with ESRD treated with hemodialysis. The median survival of the experimental group was 52 months; 1-, 2- and 6-year actuarial survival was 72, 62, and 44%, while in the control group it was 95, 91, and 81%, respectively (p less than 0.001). Survival was significantly shorter for patients with amyloidosis who rapidly (less than 3 months) progressed to ESRD or who had an acute deterioration in renal function immediately prior to the need for dialysis. The median survival in these cases was 4 and 1.5 months, respectively. Age, the presence or the degree of renal failure at the moment of diagnosis, and the type of amyloidosis did not affect the survival of these patients. Despite a shorter period of time spent on dialysis, these patients had a similar number of hospital admissions, cardiovascular and infectious events as the control patients, but more gastrointestinal disorders (bleeding and chronic diarrhea) and blood access problems. In conclusion, amyloidotic patients maintained on chronic dialysis have high morbidity and mortality rates. Nevertheless, acceptable survival is predictable in stable patients who progress slowly to ESRD.

A 41-year-old female, who had been diagnosed as having paroxysmal nocturnal hemoglobinuria (PNH) in 1985, was admitted to our hospital with cough, fever, diarrhea, vomiting and palpitation in April 1988. The chest X-ray showed pneumonia in her right lung. In the peripheral blood, red blood cell count was 1.64 x 10(6)/microliters, hemoglobin 4.7 g/dl and reticulocytes 19%. The levels of serum LDH, indirect bilirubin and creatinine were high. Pneumonia improved by the administration of antibiotics, however, anemia and renal failure deteriorated. After washed red blood cell transfusions totalling 2,000 ml and six times of hemodialysis, renal function returned to normal. This patient with PNH appeared to have developed acute renal failure by dehydration and hemolytic crisis due to pneumonia.

In the course of two and a half years we treated six diabetic women on account of lactate acidosis during concurrent biguanide administration. The patients were given an average dose of 290 mg Buformin/24 hours. Their mean age was 71 years. Three patients died, i.e. the mortality was 50%. All patients reported nausea, vomiting and abdominal pain. Two suffered from diarrhoea. Two patients suffered from renal failure and one from cardiac weakness. One patient was in coma. The mean lactate concentration was 14.7 mmol/l, pH on admission was 6.84. The patients were given on average 550 mmol bicarbonate. In two instances bicarbonate dialysis was used. The authors discuss the pathophysiology, clinical aspects and importance for treatment and prevention of lactate acidosis during biguanide treatment.

A previously healthy 35-year-old woman was seen at 37 weeks' gestation with a 10-day history of fever, vomiting, diarrhea and malaise. Serum laboratory findings included elevation of serum bilirubin and AST, prolongation of serum prothrombin time and a positive monospot. A tentative diagnosis of acute fatty liver of pregnancy was made, and a healthy male infant was delivered by emergency cesarean section because of fetal distress. Over the subsequent 3 days, acute progressive oliguric renal failure, disseminated intravascular coagulation, hypoglycemia requiring intravenous dextrose infusion and pancreatitis developed; her mental status progressed to stage III encephalopathy. Quantitative computed tomography estimated the liver volume to be 770 cm3. The decision to proceed with orthotopic liver transplantation was made on the basis of progressive clinical deterioration despite aggressive support and because of her small liver size. After transplant, the patient's multisystem failure rapidly reversed. Histopathological examination of the native liver demonstrated predominantly zone 3 microvesicular steatosis with characteristic ultrastructural changes consistent with acute fatty liver of pregnancy. Southern blot analysis for Epstein-Barr virus DNA was negative. We conclude that orthotopic liver transplantation should be considered for the small group of patients with fulminant hepatic failure associated with acute fatty liver of pregnancy who manifest signs of irreversible liver failure despite delivery of the fetus and aggresive supportive care.
