Multiple suture synostosis, macrocephaly, and intracranial hypertension in a child with alpha-D-mannosidase deficiency. Case report.

The authors present an unusual case in which increased intracranial pressure developed because of multiple-suture craniosynostosis and megaloencephaly in a child with a previously undiagnosed lysosomal storage disease, alpha-D-mannosidase deficiency. This 3-year-old boy presented with a history of frequent naps, headaches, florid papilledema, enlarged head (> 95th percentile), elevated opening pressure by lumbar puncture, a "beaten copper" appearance on skull radiographs, and no hydrocephalus. Multiple synostectomies were performed. Postoperatively, the child's headaches and papilledema resolved and his level of physical activity increased dramatically. The authors discuss the paradoxical presentation of prematurely fused sutures and macrocrania in light of this lysosomal storage disease and its subsequent management.

Neonatal hemochromatosis associated with maternal autoantibodies against Ro/SS-A and La/SS-B ribonucleoproteins.

Liver disease in the fetus and neonate may be associated with maternal Sjögren's syndrome (neonatal lupus erythematosus). The infant of a mother with Sjögren's syndrome and high anti-Ro/SS-A and anti-La/SS-B antibody titers presented at 2 1/2 weeks of age with overwhelming hepatic insufficiency and died at 6 weeks of age. Autopsy confirmed the antemortem diagnosis of neonatal hemochromatosis. We discuss the possibility of a relationship between these two conditions.

Animal-induced injuries and disease, neonatal jaundice, viral infections, and immunizations.

This section features recent information in four areas of interest to the practicing pediatrician: animal-induced injuries and disease, neonatal jaundice, viral infections, and immunizations. The focus is on areas of major current discussion: the clinical spectrum and etiology of cat-scratch disease, the debate on new neonatal bilirubin recommendations, viral etiology of previously recognized clinical diagnoses, new immunization recommendations, and new vaccines. In addition, isolated but thought-provoking papers in the four areas over the past year are briefly discussed. By paying careful attention to highlighted articles, the busy practitioner should be able to keep abreast of rapid new developments.

Orthotopic liver transplantation, Epstein-Barr virus, cyclosporine, and lymphoproliferative disease: a growing concern.

Lymphoproliferative disease (LPD) is a well-recognized complication of both solid organ and bone marrow transplantations. The occurrence of LPD in these settings is related in part to the use of the immunosuppressive agent cyclosporine. We report 12 cases of LPD after orthotopic liver transplantations in 132 pediatric patients. Lymphoproliferative disease occurred as one of three clinical syndromes: (1) lymphadenopathic, (2) systemic, and (3) lymphomatous. Effective management of LPD with excisional therapy or reduction of immunosuppressive medications or both resulted in the survival of 7 of 12 patients. In an alarming and increasing percentage of patients after orthotopic liver transplantation, progressive LPD develops with lethal outcome (5/12 patients). Early recognition of LPD and aggressive intervention may improve outcome in this group.

Varicella in pediatric orthotopic liver transplant recipients.

From May 1981 to May 1984, 90 pediatric patients underwent liver transplantation and 65 patients survived as of May 1986. Two of the nonsurvivors died with complications related to clinical varicella. Of these 67 patients (65 survivors and two nonsurvivors who died of varicella-related causes), 51 patients were determined to be varicella susceptible. Clinical disease developed in no patients with serologic evidence or clinical history of varicella prior to transplantation. Eighteen susceptible patients were exposed and received zoster immune globulin and varicella did not develop. Clinical disease developed in eight patients despite zoster immune globulin, although one patient received it 96 hours after exposure. Six patients received no zoster immune globulin and clinical varicella developed. In all, varicella developed in 14 patients. Thirteen were admitted to the hospital and treated with intravenous acyclovir. Of those treated, two died of causes related to complications of varicella. The remaining patients treated with acyclovir had mild disease. The one patient not treated with acyclovir also had mild disease. We conclude that patients contracting varicella after liver transplantation while receiving maintenance immunosuppressive agents should be treated with intravenous acyclovir. Generally, when treated with acyclovir while receiving maintenance immunosuppressive drugs, these patients have mild clinical disease. Patients recently treated with high-dose prednisone and cyclosporine may have severe clinical disease resulting in death.

Acute profound dystonia in infants with glutaric acidemia.

Acute profound dystonia developed in three previously well infants who were found to have glutaryl-CoA dehydrogenase deficiency in cultured skin fibroblasts. Two patients had excessive urinary excretion of glutaric acid, but one did not. Neuroradiologic studies performed in all three patients at the onset of their illnesses revealed large CSF-containing spaces both within the sylvian fissures and anterior to the temporal lobes. Pathologic examination of the brain of one patient demonstrated cerebral and cerebellar atrophy, shrinkage of the putamen, and white matter vacuolation. Glutaric acidemia may be a common cause of acquired persistent dystonia or choreoathetosis in infancy.

Kawasaki disease and perineal rash.

During the past several years, we treated seven children with Kawasaki disease who developed a distinctive but rarely described perineal rash. This rash began three to four days from onset of the illness and desquamated in all instances by days 5 to 7. The presence of this rash may facilitate early diagnosis of Kawasaki disease and, hence, may influence the initiation of early treatment.

Changes in life-style after liver transplantation.

Sixty-five pediatric patients who received liver transplants between May 1981 and May 1984 were observed for as many as 5 years and examined for changes in life-style. Children were less frequently hospitalized, spent less time hospitalized, required fewer medications, and generally had excellent liver and renal function after hepatic transplantation as compared with their pretransplantation status. Most children were in age-appropriate and standard school classes or were only 1 year behind. Cognitive abilities remained unchanged. Children improved in gross motor function and patients' behavior significantly improved according to parents' perceptions. Enuresis was more prevalent, however, than in the population of children who had not received liver transplants. Parental divorce rates were no greater than those reported for other families with chronically ill children. Overall, objective changes in life-style as well as parents' perceptions of behavior of children appear to be improved after liver transplantation.

Successful treatment of homozygous protein C deficiency by hepatic transplantation.

A child with homozygous protein C deficiency was treated at age 20 months by orthotopic hepatic transplantation. Postoperatively there was complete reconstitution of protein C activity and resolution of the thrombotic condition.

Munchausen's syndrome by proxy and its professional participants.

Physicians and legal and protective service agencies may unwittingly participate in Munchausen's syndrome by proxy (MSP) when they fall to recognize MSP, treat the true disorder, and effect a favorable outcome for the child. Five patients with MSP are described, emphasizing a variety of presentations, often with a delay in diagnosis. In addition, features in the family unit are identified to aid in early recognition of the disorder, and a management protocol used at Children's Hospital of Pittsburgh is presented. Finally, the need for better care, recognition, and reporting to help determine the true incidence of the disorder and aid in educating involved professionals is emphasized.

Choosing a pediatric recipient for orthotopic liver transplantation.

Between March 3, 1981, and June 1, 1984, 216 children were evaluated for orthotopic liver transplantation. Of the 216 patients, 117 (55%) had received at least one liver transplant by June 1, 1985. Fifty-five (25%) died before transplantation. The 117 patients who received transplants were grouped according to severity of disease and degree of general decompensation at the time of transplantation. The severity of a patient's medical condition with the possible exception of deep hepatic coma, did not predict outcome following orthotopic liver transplantation. Seventy variables were assessed at the time of the evaluation. Twenty-three of the 70 variables were found to have prognostic significance with regard to death from progressive liver disease before transplantation. These 23 variables were incorporated into a multivariate model to provide a means of determining the relative risk of death among pediatric patients with end-stage liver disease. This information may allow more informed selection of candidates awaiting liver transplantation.

Pediatric liver transplantation: patient evaluation and selection, infectious complications, and life-style after transplantation.

Liver transplantation is an increasingly accepted treatment for children with end-stage liver disease. Evaluation of the patient and appropriate patient selection for transplantation will become increasingly important issues as more and more children come to transplantation and compete for available organs. Numerous complications occur after transplantation, including infections. We have summarized our experience with bacterial, fungal, and viral infections in these patients and emphasize the need for continued improvement in immune suppressive drugs and regimens to minimize such complications. And finally, information presented on 65 pediatric patients followed 2 to 5 years suggests that, despite numerous complications and often prolonged hospitalization for transplantation, life-style after transplantation appears to be significantly improved.

Myasthenia gravis associated with human T-cell lymphotropic virus type III infection.

A 15-year-old boy is described with myasthenia gravis, hemophilia A, positive HTLV-III serology, antithyroglobulin and antimicrosomal antibodies, and laboratory evidence of altered cell-mediated immunity. Treatment with pyridostigmine produced dramatic clinical improvement. The results of this patient raise the possibility of myasthenia gravis as the sole or presenting clinical manifestation of infection with HTLV-III.
