Since the mid-1960s, millions of dollars in federal funds have been used for research in the development of the Total Artificial Heart (TAH). Significant advances in bio-materials and pump and energy systems, as well as animal experimentations, have led to the clinical reality of the TAH's use in man. On December 2, 1982, Dr. Barney Clark became the first recipient of a permanent TAH. He had been suffering from terminal congestive heart failure secondary to idiopathic cardiomyopathy. No other treatment was available, since, at the age of 61, he was too old for heart transplant. Dr. Clark's 112-day hospitalization was complicated by pulmonary problems, renal insufficiency, seizures, nosebleeds, and a broken heart valve. Dr. Clark appeared malnourished before surgery, and his numerous postoperative complications confounded attempts at nutritional support. Standard nutritional assessment techniques were inadequate or inappropriate in the face of severe edema, renal failure, and multiple transfusions. Although nitrogen balance was achieved intermittently, for the majority of his hospitalization Dr. Clark remained in negative nitrogen balance, due mainly to renal insufficiency. Some of the nutritional complications seen in the first TAH patient might have been preventable with early nutritional assessment and more aggressive support. The Artificial Heart Management Team at the University of Utah now includes a nutritionist, and future protocols outline detailed nutrition monitoring.

Three cases are presented, in two of which the CNS lesions revealed the presence of systemic lupus erythematosus (SLE). The diagnosis of SLE was certain according to the criteria of the ARA, and it was further confirmed by results of renal needle puncture biopsy. Case 1: A 16-year-old adolescent developed choreic movements followed, one month later, by psychotic symptoms suggesting a mixed hebephrenic-catatonic schizophrenic affection. Cutaneous lesions and signs of renal insufficiency 3 months later established that these disorders were related to SLE. A favourable outcome was observed rapidly for the systemic signs, recovery from neuropsychic symptoms being obtained after 3 months only but then in a few days. This course suggests the diagnosis of a "functional psychosis" of lupus origin. Case 2: A 24-year-old woman developed left hemiparesis followed by febrile coma. The slowly favourable course of the disease led to the appearance of a progressive dementia, with numerous epileptic seizures. Although tests for antinuclear antibodies were negative and the ESR was normal, several minor biological anomalies were suggestive of a systemic disease and the diagnosis of SLE was finally established. Corticotherapy produced only slight transient improvement. This progression towards dementia with progressive cerebral atrophy is most probably related to cerebral lupus lesions, the initial coma in the absence of any other apparent cause possibly being the first sign. Case 3: A 47-year-old woman developed simultaneously or separately episodes of arthralgia and uveitis of unknown origin over a 12-year period, and attacks of regressive multilocular neurological deficiency over a 15-year period.(ABSTRACT TRUNCATED AT 250 WORDS)

A child with renal insufficiency was treated with the oral phosphate binder aluminum hydroxide from age 6 to 31 months. The prescribed dose of elemental aluminum varied from 31 to 108 mg/kg/d. Concurrently the patient developed vitamin D-resistant osteomalacia which failed to improve with parathyroidectomy. Encephalopathy with myoclonic seizures, loss of speech, and motor impairment also occurred. Serum and bone aluminum levels were elevated at 334 micrograms/L (normal 7 +/- 3 micrograms/L) and 156 mg/kg (normal 3.3 +/- 2.9 mg/kg), respectively. This case demonstrates that aluminum may accumulate in tissue of children receiving oral aluminum hydroxide. The accumulation of aluminum may have contributed to the vitamin D-resistant osteomalacia and the encephalopathy in this patient. Children receiving aluminum-containing antacids as phosphate binders should be monitored for aluminum accumulation and signs of aluminum intoxication.

A girl presented with small stature, obesity, tapetoretinal degeneration, deafness, psychomotor regression, seizures, acanthosis nigricans, hepatomegaly, and chronic tubulointerstitial nephropathy. She died at age ten with renal insufficiency and uncontrolled seizures. Histochemistry showed lipid storage in hepatocytes, histiocytes, smooth muscles and, to a much lesser extent, kidney tubules and cortical neurons. The liver had increased cholesterol esters (5-fold) and triacylglycerols (8-fold), and decreased phospholipids (50%). Methyllumbelliferyl-oleate, oleylcholestrol, trioleylglycerol, and tripalmitylglycerol lipase activities were markedly reduced in the liver, in the range found in Wolman's disease. In cirrhotic fatty livers these activities ranged from 7-87% of the normal mean. The patient's brain had limited neutral lipid storage and normal methyllumbelliferyl-oleate lipase. Trioleylglycerol lipase activity was 14-60% of controls; tripalmitylglycerol lipase activity 14-25% of controls; and oleylcholestrol lipase activity 12-33% of controls.

The author reviewed records of 10 patients who had experienced acute loxapine overdose. The most frequent medical complications were CNS depression, sinus tachycardia, hypertension, and hypothermia; 6 patients had had generalized major motor seizures, 1 had had recurrent paroxysmal atrial tachycardia, and 2 had had transient renal insufficiency from rhabdomyolysis and myoglobinuria. Other clinical effects from loxapine overdose were predominantly anticholinergic. The author recommends that loxapine-overdose patients receive ECG monitoring and treatment of medical complications in an intensive care unit.

Erythropoietin, a glycoprotein, is synthesized mainly in the kidney. With the destruction of renal tissue, erythropoietin production decreases; this is a major factor in the development of anemia in patients with renal failure. For about ten years now, recombinant human erythropoietin has been available for the treatment of renal anemia. All patients with renal insufficiency, independent of their plan for future renal replacement therapy, may benefit from erythropoietin. At what extent of anemia erythropoietin therapy should be started is still discussed and is certainly dependent on the degree of the patient's impairment by his anemia. Before beginning a therapy with erythropoietin, other forms of anemia observed in patients with renal failure, i.e. mainly iron deficiency, have to be excluded. A strict monitoring of hematocrit during treatment with erythropoietin is mandatory. Hypertension, seizures and cardiovascular complications have been observed with overdosing of erythropoietin. Special emphasis of this review is therefore put on the discussion of the dynamics of the erythropoietin-red cell system.

The introduction of cyclosporine A (CsA) and FK506 significantly improved the outcome of liver transplantation. However, the postoperative course and outcome of liver transplant recipients in still compromised by rejection, over-immunosuppression-induced infection and immunosuppression-associated toxicity. In the present study, we evaluated the reason for conversion between immunosuppressive regimens in 121 patients, 60 treated with FK506 and 61 patients treated with CsA-based immunosuppression. Five patients treated primarily with CsA (8.3%) were converted to FK506 therapy because of refractory acute of chronic rejection within 12 months following liver transplantation (LTX). In 2 patients, conversion was performed after Re-LTX. In 4 of these 5 patients, rejection was successfully treated according to histological and laboratory investigations, while in the remaining patient, graft function improved with persisting histological evidence of chronic rejection. Moderate and severe neurologic symptoms during the early postoperative period, i.e. organic brain syndromes (OBS), seizures, hemiparesis, dysphasia, dysathria and cerebellar symptoms were observed in 21.3% of patients treated with FK506 and in 11.7% of patients treated with CsA (p = n.s.). Five patients treated primarily with FK506 were converted to CsA due to severe neurotoxicity. Early postoperative renal insufficiency was observed to a similar extent with 42.6% of FK506- and 36.7% of CsA-treated patients. 8.3% of FK506-treated patients and 11.7% of CsA-treated patients required hemodialysis (p = n.s.) There patients were converted from FK506 to CsA due to persisting renal insufficiency. Moderate and severe neurologic symptoms were observed more frequently under treatment with FK506 than CsA, and all conversions from FK506 to CsA (13.3%) were performed because of neuro- or nephrotoxicity.(ABSTRACT TRUNCATED AT 250 WORDS)

A now 33-year-old woman first had psychomotor seizures at the age of 3 years. At 9 years tuberous sclerosis (Bourneville-Pringle disease) was diagnosed, on the basis of sebaceous adenoma, white spots of the skin and periventricular cerebral calcifications. Later she developed hyperostoses of the cranium and two periungual fibromas. When aged 23 years she was first noted to have borderline hypertension (145/95 mmHg) and signs of renal insufficiency which, over the subsequent 10 years, gradually worsened: computed tomography and magnetic resonance imaging demonstrated angiolipomas and cysts. Haemodialysis became necessary when serum creatinine level had risen to 9.0 mg/dl, creatinine clearance to 8 ml/min, with proteinuria of 2660 mg/24 h and metabolic acidosis (pH 7.17, base excess -8.1 mmol). She had no mental retardation nor other neurological deficits and is scheduled to have renal transplantation. There were no hamartomas in other organs.

Renal angiomyolipoma is common in the tuberous sclerosis complex (TSC), the classic features of which are facial angiofibroma, seizures, and mental retardation. We report a family with three affected members demonstrating the wide spectrum of TSC-associated lesions ranging from asymptomatic findings to life-threatening complications. The predominant symptoms of the index patient were hypertension and mild renal insufficiency at age 48, resulting in end-stage renal failure at age 63 due to giant bilateral angiomyolipoma of the kidneys. The two TSC-affected siblings had died years previously, one from pulmonary lymphangioleiomyomatosis and the other during an epileptic state; the latter had situs inversus totalis as another remarkable finding. The diagnosis of TSC may be overlooked if CNS symptoms are absent and if cutaneous lesions are masked by cosmetic procedures, as occurred in the index case. Chronic renal failure due to angiomyolipoma is not widely known to clinical nephrologists, but develops in approximately 15% of TSC patients. Displacement of functional renal parenchyma by abnormal tissue appears to be the major pathogenetic mechanism leading to end-stage renal failure. Angiomyolipomas can be diagnosed from this characteristic sonographic pattern and the demonstration of fatty tissue in CT or MRI. Multiple renal cysts are also common in TSC. Therefore TSC should be considered in the differential diagnosis of polycystic kidney disease.

Ten patients with hemolytic uremic syndrome (HUS) were admitted to our ICU during the last 7 years. The mean age at entry was 26 month old. Only one child was more than 2 years of age. A greater incidence of this illness was noted during the summer season. Almost all cases (90%), were severe with arterial hypertension and requiring peritoneal dialysis. HUS is a multisystemic disorder with early renal involvement, but the possibility of other sites being affected must be kept in mind. Half of the patients presented extrarenal manifestations of disease, including: seizures (30%), colonic ischemia requiring intestinal resection, and heart failure with lung edema due to severe hypertension. The two parameters that were helpful in determining the prognosis were the interval of renal insufficiency (greater than 14 days) and neurologic impairment, with the later being of most importance.
