Thirteen out of 268 children (less than 18 years old) underwent hepatic transplantation (OLT) for end-stage liver disease (ESLD) associated with arteriohepatic dysplasia (AHD). Seven children are alive and well with normal liver function. Six children died, four within 11 days of the operation and the other two at 4 and 10 months after the OLT. Vascular complications with associated septicemia were responsible for the deaths of three children. Two died of heart failure and circulatory collapse, secondary to pulmonary hypertension and congenital heart disease. The remaining patient died of overwhelming sepsis not associated with technical complications. Seven patients had a portoenterostomy or portocholecystostomy early in life; five of these died after the OLT. Severe cardiovascular abnormalities in some of our patients suggest that complete hemodynamic monitoring with invasive studies should be performed in all patients with AHD, especially in cases of documented hypertrophy of the right ventricle. The improved quality of life in our surviving patients confirms the validity of OLT as a treatment of choice in cases of ESLD due to AHD.

Fifty-one patients under the age of 18 with histologic-proven malignant urinary tract tumors were encountered at the Department of Pediatrics of National Taiwan University Hospital from 1979 to 1989. There were 47 tumors arising from the kidney, 2 from the bladder, and 2 from the urethra. For upper urinary tract tumors, abdominal mass (92%) and abdominal distension (86%) were the most common symptoms and signs. For lower urinary tract tumors, painless hematuria, bladder distension and urinary difficulty were most frequently encountered. Associated anomalies were found in one-fifth of our patients, including kyphosis, undescended testes, hypospadias, inguinal hernia, intersex and congenital heart disease. Diagnosis was aided by plain X ray, abdominal ultrasonography, intravenous pyelography, computed tomography, or angiography in upper urinary tract tumors, and cystoscopy, cystography and computed tomography in lower urinary tract tumors. Multimodal treatment including total excision, multiagent chemotherapy, and radiotherapy were performed. Postoperative complications included infection (22%), ascites (19%), ileus, pleural effusion, scoliosis, neuropathies, and growth retardation. The local recurrence rate was 32%, and the metastatic rate was 34%. The overall mortality rate was 53% for an average follow-up period of 38 months. The causes of death included sepsis, respiratory failure and hepatic failure. The two-year survival rate was 47.6%. The important prognostic factors included histology, staging and vascular invasion, in addition to combined chemotherapy and radiotherapy.

Seventeen infants less than 1 year of age have undergone heart (12), heart-lung (3), and lung (2) transplantation for end-stage cardiopulmonary disease. The infants undergoing heart transplantation had a mean age of 4.5 months (range, 19 days to 12 months) with the diagnosis of cardiomyopathy in 4 and congenital heart disease in 8. Four of the 8 patients (50%) had hypoplastic left heart syndrome. Actuarial survival at 1 and 2 years was 74% and compared favorably with the survival of older children at 1 and 2 years of 82% and 69%. The linearized rejection rate was less in infants as compared with children more than 1 year of age (0.61 versus 1.48 episodes per 100 patient days). In intermediate follow-up, no graft atherosclerosis has been noted. Immunosuppression has included a three-drug protocol of cyclosporine, azathioprine, and prednisone. A steroid taper to alternate day steroids or off completely by 6 months has been the goal and has been accomplished in 6 of 12 infants. Heart-lung and lung transplantation has been performed in 5 infants. One infant in each group died: 1 infant secondary to airway complications and sepsis and another due to pulmonary sepsis. A pulmonary lobe from a larger and older donor was transplanted into a 4-week-old infant as a single-lung transplant with good outcome. The 3 surviving infants are well 24, 18, and 2 months after transplantation. Obliterative bronchiolitis has not been clinically apparent in this group. These data support the clinical efficacy of heart, heart-lung, and lung transplantation in the first year of life.

We have previously shown the safety and efficacy of University of Wisconsin solution for hypothermic preservation of the human donor heart in a pilot group of 16 transplant recipients. The present study is a randomized clinical trial comparing University of Wisconsin solution to conventional preservation using crystalloid cardioplegia and saline storage within a 4-hour limit of ischemia. Heart transplant recipients (n = 42) were randomized into two groups: those receiving hearts preserved by University of Wisconsin solution, the UWS group (n = 22), and those receiving hearts preserved in the conventional manner, the CCS group (n = 20). Recipient age, gender, heart disease, and preoperative inotropic support and donor age, gender, and mean ischemic time in hours (UWS 2 hours 36 minutes, range 1 hour 36 minutes to 2 hours 53 minutes; CCS 2 hours 20 minutes, range 1 hour 20 minutes to 2 hours 44 minutes; p = not significant) were similar. Significant differences observed between the two groups included (1) mean time (minutes) from reperfusion to achieve a stable rhythm, (2) need for intraoperative defibrillations, (3) need for transient cardiac pacing, and (4) integrated postoperative creatinine kinase and aspartate aminotransferase release over 48 hours. There was no difference in postoperative electrocardiogram, endomyocardial biopsy, or hemodynamics. One UWS patient died of sepsis and another of a ruptured cerebral aneurysm. UWS is safe for donor organ arrest and preservation despite high viscosity and potassium concentration. When compared with CCS hearts, hearts preserved in UWS regained electrical activity more rapidly and had better myocardial protection as demonstrated by enzymatic analysis. Further investigation is required to determine the effects of UWS preservation on long-term survival, to determine the prevalence of rejection and graft atherosclerosis, and to test the ability of UWS to extend donor ischemic time in human cardiac transplantation.

Perioperative circulatory disorders in patients may take the form of a transitory reduction in oxygen transport to the peripheral tissues (pre-shock), manifest circulatory insufficiency in the presence or absence of concomitant heart insufficiency or general congestive heart failure due to the destabilization of an preexisting heart disease. The least problematical stage in this programme of therapy is the treatment of transitory perioperative circulatory insufficiency by manipulation of the oxygen transport system using the following means: comparative volume optimization [according to the central venous pressure (CVP)], positive inotropic support with dobutamine (5-10 micrograms.kg-1.min-1), monitoring of the blood pressure, heart rate and oxygen consumption and, in severe cases, insertion of a Swan-Ganz catheter. In manifest circulatory insufficiency, sepsis or acute congestive heart failure, the Swan-Ganz catheter seems to be obligatory. In such cases, the positive inotropic therapy is based on catecholamines of medium (dobutamine) or high (epinephrine) positive inotropic efficacy, as a normal pattern and functioning of beta-adrenoceptors can be assumed in such cases if there is no history of cardiac insufficiency. The systemic vascular resistance (SVR) is adjusted to 800-1200 n.s.cm-5 to relieve the working capacity of the heart and to maintain sufficient perfusion pressure by means of constrictors (phenylephrine, norepinephrine) or dilators [nifedipine, nitroglycerin or, if necessary, angiotensin-converting-enzyme (ACE) inhibitors].(ABSTRACT TRUNCATED AT 250 WORDS)

The authors describe a case of fatal acetaminophen overdose which occurred in a 16-year-old female. Her serum acetaminophen concentration 11.5 h postingestion was 154 mg/L. Antidotal therapy was unsuccessful, and after 9 days she died. Autopsy findings included centrilobular zonal liver necrosis, acute proximal renal tubular necrosis, and diffuse alveolar pulmonary damage. Her heart was transplanted into a young woman with congenital heart disease. The recipient expired 14 days after the transplant as a result of sepsis complicating bowel ischemia. The transplanted heart showed extensive subendocardial myocyte necrosis related to acetaminophen toxicity and not rejection.

Orthotopic cardiac transplantation has become established for selected infants with severe forms of congenital heart disease. This study reviews the combined experience and intermediate term results of infants undergoing orthotopic cardiac transplantation from Children's Memorial Hospital, Chicago, and Kosair Children's Hospital, Louisville. From June 1986 through December 1989, 20 orthotopic cardiac transplantations were performed in 19 patients. Sixteen patients had variants of hypoplastic left heart syndrome. One infant had anomalous origin of the left coronary artery with severe ischemic cardiomyopathy. Two infants had aortic stenosis with endocardial fibroelastosis, and one had extracorporeal membrane oxygenation as a bridge to transplantation. Immunosuppression included cyclosporine, azathioprine (Imuran), and corticosteroids with an effort to wean the patients from steroids by 6 months to 2 years. Three early deaths resulted--from technical errors in two patients and from hyperacute rejection in one patient at 3 days. Four late deaths have occurred. Two patients died at 2 and 13 months of acute rejection. One patient died at 15 months of acute rejection after retransplantation. One patient died at 7 months of respiratory syncytial viral pneumonia. The remaining 12 patients are surviving 5 to 47 months (means 20 months) after orthotopic cardiac transplantation. Rejection surveillance in the first 6 months is by clinical signs supplemented by echocardiography, electrocardiography, and cell cycle analysis; endomyocardial biopsy is used after 6 months of age. For the cumulative series, 24 episodes of suspected rejection have been treated during 277 at-risk patient months with intravenous methylprednisolone (Solu-Medrol) (n = 18) and monoclonal antibody (OKT3) (n = 6), for an incidence of 1.04 episodes of rejection per patient per year. Serious posttransplantation infections including endocarditis, catheter sepsis, meningitis, and colonic perforation were successfully treated in four patients. Subjectively, their quality of life is excellent as shown by normal growth and developmental milestones and a low hospital readmission rate (1.4 episodes per patient per year). These encouraging intermediate term results warrant continued application of infant orthotopic cardiac transplantation for severe forms of congenital heart disease.

Obstructive jaundice has been known to cause severe hemodynamic disturbance. The present study was therefore designed to assess the cardiac involvement in jaundiced patients. The multiple-gated blood pool cardioscintigraphic studies were done in 9 jaundiced patients who had either cholestatic or obstructive jaundice (mean total bilirubin 29.30 +/- 3.30 mg/dL), and in 8 normal volunteers (total bilirubin less than 1 mg%). None of the patients had evidences of obvious cirrhosis, intrinisic heart disease, or septicemia. Following intravenous dobutamine there was comparable change of blood pressure and heart rate in both groups. However the response of left ventricular ejection fraction (LVEF) to dobutamine (10 micrograms/kg/min x 5 min) was strikingly blunted in the jaundiced patients as compared to that seen in the normal controls (3.56 +/- 0.9 vs. 12.7 +/- 2.2%, p less than 0.005). Our present data thus show that there is blunted myocardial contractile response to the inotropic stimulation in jaundiced patients. Such myocardial refractoriness to beta-1 stimulation may contribute to the susceptibility of jaundiced patients to postoperative shock and acute renal failure.

The advances in the antibiotic therapy of acute bacterial infections can be shown by the decreasing frequency of complications and fatalities in children. The annual death-rate from pneumonia in children aged one month to 15 years has fallen in Schleswig-Holstein from 1.8 (1954-1958) to 0.6 per 10,000 (1969-1973). At the same time the total death-rate in the same age group has fallen from 14.5 to 9.3 per 10,000 children. The percentage of pneumonia in the total death-rate was 5.3% in 1971-1973: 1.6% in the first month of life and after the sixteenth year 2.3%. Pneumonia was in fourth place (after accident, malformation and neoplasm) as a cause of death in children more than one month old. Of 245 children operated on for congenital heart disease in 1983-1984, bacterial and fungal infections occurred in 3.6% compared to 17.8% of 469 in 1968-1972. Staphylococcal infections decreased from 3.4% to 0.8% and those caused by gram-negative bacteria from 6.9% to 0. Perioperative prophylaxis was performed with cefotaxime plus piperacillin in 1983-1984 versus oxacillin plus ampicillin in 1968-1972. Between 1984 and 1989, 944 children (premature babies and term babies) were treated in the intensive care unit of the University Children's Hospital of Kiel. The incidence of sepsis was 5% (congenital sepsis 4%, sepsis acquired after birth 1%). Early diagnosis and treatment of severe bacterial infections with cefotaxime plus piperacillin reduced the mortality rate of sepsis to 2%. Sepsis never developed under treatment with cefotaxime plus piperacillin.(ABSTRACT TRUNCATED AT 250 WORDS)

A 1-month-old boy without precedent clinical signs of heart disease died unexpectedly. At autopsy, the child was found to have origin of the right coronary artery from the left sinus of Valsalva immediately leftward to the thickening of the aortic wall at the cuspal commissure and adjacent to the ostium of the left main coronary artery. The association of this coronary anomaly with otherwise unexplained prenatal or early postnatal death has only recently been appreciated as a potential cause of sudden infant death and mimic of sepsis, dysrhythmias, congestive heart failure, or metabolic storage diseases.
