Twenty infants and young children with hereditary fructose intolerance (HFI) were admitted to hospital. None was diagnosed at admission. Referals were for vomiting of unknown aetiology (16X), pyloric stenosis or hiatus hernia (5X), toxic condition (3X), and hepatomegaly of unknown origin (5X). Feeding difficulties (20X), vomiting (18X), and failure to thrive (16X) were leading symptoms. The most frequent clinical findings were hepatomegaly (18X), pallor (14X), haemorrhages (13X). Ascites, oliguria, tachypnoea, fever, splenomegaly and rickets were less frequent. Laboratory findings were indicative of disturbed hepatic and renal tubular function and also of disturbed intermediary metabolism (hypokaliaemia, hypophosphataemia). However, hypoglycaemia was found in only 4 out of 15 patients tested. Differential diagnosis after hospital admission centered on metabolic disorders such as glycogenoses, galactosaemia, tyrosinosis, or Wilson's disease. Hepatitis, toxic hepatosis, liver tumour, intrauterine infection and sepsis were also considered. Eleven children had first ingested fructose within the first 6 weeks of life. The diagnosis was usually established only many weeks or months after first fructose intake and appearance of symptoms. This documents how difficult the diagnosis of this disease can be both in practice and in hospital. The course was severe in 11 children and lethal in 4. In only 5 patients was the course mild. The 16 survivors are doing well under fructose-exclusion diet. Irreversible visual impairment after intraocular haemorrhage occurred once. In each case HFI could have been suspected immediately, had a detailed nutritional history been taken. Practising paediatricians should know the composition of commonly used infant formulae. They should never prescribe sugared condensed milk for intractable vomiting prior to excluding HFI. Solution for intravenous infusion containing fructose and sorbitol are life-threatening for undiagnosed HFI patients.

Congenital hepatic fibrosis (CHF) is a recognized cause of portal hypertension with oesophageal varices, gastro-intestinal haemorrhage and cholangitis in children without significant impairment of hepatic or renal function. This report describes the varied clinical presentation of CHF as seen at King Faisal Specialist Hospital and Research Centre (KFSH & RC) and emphasizes the clinical patterns that should enable a pediatrician to consider the diagnosis. Fourteen children with CHF were diagnosed between 1981 and 1988. The age at presentation ranged from 1.8-14 years (mean: 7.5 years); clinical manifestations at diagnosis were splenomegaly (12), hepatomegaly (11), failure to thrive (10), marked abdominal distention (4), and fever (4). Liver function tests were normal except for high alkaline phosphatase. Eight patients had polycystic kidneys confirmed on ultrasound examination. Upper gastro-intestinal endoscopy showed oesophageal varices of variable severity in all eight patients examined. Splenoportography revealed splenic vein occlusion in one patient. One patient died within days of admission with convulsions, coma, and aspiration pneumonia. One patient was lost to follow-up. The remaining 12 patients are all alive and receive regular follow-up. Two patients required splenorenal shunt. In view of the prevalence of consanguinity in Saudi Arabia, the diagnosis of CHF should be considered in children with hepatomegaly despite normal liver function tests, and particularly in those with renal abnormalities and/or evidence of portal hypertension.

The predominantly heterosexual transmission of human immunodeficiency virus (HIV) in Africa suggests that pediatric acquired immunodeficiency syndrome (AIDS) could develop into a significant child health problem in this region. To assist clinicians in recognizing HIV infection in African children, the clinical features of 185 children with symptomatic HIV-related disease diagnosed at the 2 central hospitals in Harare, Zimbabwe, from April 1986-July 1987 were enumerated. In this period, 185 such cases were diagnosed. 83 (47%) involved children 0-12 months of age and another 61 (35%) represented children 13-24 months old. The male/female ratio was 1.0:1.03. The most frequently recorded clinical feature (52% of cases) was generalized lymphadenopathy, with or without hepatosplenomegaly. 45% of HIV-infected children presented with respiratory symptoms and pulmonary infiltrates on chest x-ray. Failure to thrive was present in 38% of cases. Also relatively common were hepatomegaly and splenomegaly (35% and 26%, respectively). Chronic, recurrent diarrhea was present in 21%. Less frequently observed (under 10% of cases) clinical findings were maculopapular eczematoid rashes, parotid swelling, chronic suppurative otitis media, chronic mucopurulent rhinitis, meningitis, and encephalopathy. 3 main clinical modes of presentation were identified--children with failure to thrive or marasmus in association with chronic diarrhea and developmental delay, those with generalized lymphadenopathy and hepatosplenomegaly, and children who present with chronic cough with pulmonary infiltrates on chest x-ray.

A 6-yr-old girl is described who presented with failure to thrive at age 3 months and was found to have mental retardation, growth retardation, disproportionately large head, distinctive face, abnormal hair, eczema, heart defect, splenomegaly, and multiple hemangiomata. She is thought to have the cardio-facio-cutaneous syndrome and to be the first such case identified in Britain.

Eighty per cent of children with AIDS acquire their infection perinatally from infected mothers. Symptoms and signs appear in the first year of life and include failure to thrive, an increased number of bacterial infections, hepatomegaly, splenomegaly, lymphadenopathy, and progressive encephalopathy. Serious and multiple opportunistic infections are the rule. Antibody tests are difficult to interpret in the first year of life because of the presence of transmitted maternal antibodies. Management includes vigorous therapy for infections and attention to caloric intake and other aspects of child life, that is, foster care, day care, and schooling. Specific antiretroviral therapy is not yet established. Monthly intravenous immunoglobulin and sulfa-trimethoprim are recommended to prevent infections. The key to prevention is education.

The clinical, biochemical, and histological features of 27 children with syndromic paucity of the interlobular bile ducts are described. All presented in the first 5 months of life, 21 with jaundice, two with spontaneous bleeding due to vitamin K malabsorption in addition to jaundice, two with pruritus, and two with failure to thrive. Interlobular bile ducts were abundant in liver biopsies from five (18% of cases) in the first 6 months of life. The degree of portal fibrosis and cellular infiltrate was mild in all except three patients. Clinically significant heart lesions occurred in 52% but only 22% had peripheral pulmonary stenosis. Characteristic facial appearances were present in only 70%; embryotoxon and vertebral anomalies were present in 56 and 33%, respectively. Two infants died of cardiovascular complications, one of alimentary bleeding and one of progressive liver disease. Complications of vitamin K deficiency occurred in 15%, vitamin D deficiency in 30%, and vitamin E deficiency in 37%. Survivors at ages of 19 months to 16.5 years had considerable morbidity with pruritus occurring in 70%, jaundice in 48%, xanthomas in 30%, 74% having hepatomegaly and 63% splenomegaly. All had abnormal biochemical tests of liver function, 90% had growth retardation, and 50% developmental delay. We conclude that differentiation from extrahepatic biliary atresia can be difficult if biliary flow cannot be demonstrated. Prevention of fat-soluble vitamin deficiency is essential. Further research is required to decrease the morbidity associated with this syndrome in infancy.

Children with sickle cell disease in Nairobi come from tribes living in malarial regions of Kenya. The clinical presentation and complications of this disease are described. The symptoms at onset are nonspecific but the typical features that follow are easy to recognize. Cardiac murmurs and persistently enlarged spleen in older children pose diagnostic challenges. Poor appetite and failure to thrive are common; so are school absenteeism due to crises and infection. The use of white blood cell counts to determine the presence of infection during crises is described.

Clinical and hematological features of nine cases of Hemoglobin E variant were studied prospectively over three years. There were three cases of HbE-beta thalassemia and six cases of homozygous HbE disease. Two cases were asymptomatic. The commonest symptom was jaundice (unconjugated 2). Other symptoms were left hypochondrial pain, tiredness, syncope and failure to thrive. Splenomegaly and microcytosis was detected in all. Mild anaemia was present in majority (6/9), and the mean hemoglobin was 11.3 gm/dl. Reticulocyte count was normal in all and cholelithiasis was seen in one patient only. Clinical and hematological features were evaluated and compared to reported series. Splenomegaly was found to be more common.

In order to study the functions of simian immunodeficiency virus (SIV) Nef in vivo in a small-animal model, we constructed transgenic (Tg) mice expressing the SIV(mac)239 nef gene in the natural target cells of the virus under the control of the human CD4 gene promoter (CD4C). These CD4C/SHIV-nef(SIV) Tg mice develop a severe AIDS-like disease, with manifestations including premature death, failure to thrive or weight loss, wasting, thymic atrophy, an especially low number of peripheral CD8+ T cells as well as a low number of peripheral CD4+ T cells, diarrhea, splenomegaly, and kidney (interstitial nephritis, segmental glomerulosclerosis), lung (lymphocytic interstitial pneumonitis), and heart disease. In addition, these Tg mice fail to mount a class-switched antibody response after immunization with ovalbumin, they produce anti-DNA autoantibodies, and some of them develop Pneumocystis carinii lung infections. All these results suggest a generalized Nef-induced immunodeficiency. The low numbers of peripheral CD8+ and CD4+ T cells are likely to reflect a thymic defect and may be similar to the DiGeorge-like "thymic defect" immunophenotype described for a subgroup of human immunodeficiency virus type 1-infected children. Therefore, it appears that SIV Nef alone expressed in mice, in appropriate cell types and at sufficient levels, can elicit many of the phenotypes of simian and human AIDS. These Tg mice should be instrumental in studying the pathogenesis of SIV Nef-induced phenotypes.

Recent advances in immunologic techniques have lead to increased recognition of primary immunodeficiencies. A review of patients with suspected immunodeficiencies in a Taiwan tertiary hospital from January 1985 to October 2004 and molecular/genetic analyses done on some patients were investigated. Of the 403 patients selected based on the International Classification of Disease, Ninth Revision, 37 patients with PID (8 females and 29 males) were identified: 17 (46%) with antibody production deficiencies, nine (24%) with defective phagocyte function, four (11%) with combined B and T cell immunodeficiencies, seven (19%) with T cell deficiencies, but none with primary complement deficiencies. Those with secondary immunodeficiencies were excluded from the study. Recurrent sinopulmonary infections (62%) were the most common clinical manifestation, followed by sepsis (57%), severe skin infection (40%), splenomegaly/hepatomegaly (27%), central nervous system dysfunction (22%), chronic diarrhea (22%), and failure to thrive (19%). Seven (19%) patients died, five of infections, one of disseminated intravascular coagulopathy and one of hepatocellular carcinoma. Six novel mutations were found from 11 agreed patients. This is the first report on primary immunodeficiencies in Taiwan covering a 20-year period.
