The first twenty-one cases of Paediatric Acquired Immunodeficiency Syndrome (PAIDS) in Trinidad and Tobago were studied. An overwhelming majority of patients were of African descent. Most of the children presented within the first year of life, the average time between presentation and death was 4 1/2 months, and the majority presented with either diarrhoea or pneumonia or failure to thrive, common conditions in the West Indies. Fever lasting longer than two weeks as well as hepatomegaly were clues which led to a definitive diagnosis.

Most inborn errors of intermediary metabolism presenting in the neonatal period fall schematically into three clinical categories: (1) those which lead to a neurological distress 'intoxication type' with a symptom-free interval, vomiting, comas, hypertonia, abnormal movements and frequent humoral disturbances (organic acidaemias, congenital urea cycle defects); (2) those which lead to a neurological distress 'energy deficiency' type. Frequent symptoms in this group include hyperlactacidaemia, severe hypotonia, cardiomyopathy, failure to thrive and malformations (congenital lactic acidaemias, fatty acid oxidation defects, peroxysomal disorders); (3) those which present evidence of liver dysfunction and hepatomegaly (glycogenesis, neoglucogenesis defects, galactosaemia, fructosaemia, tyrosinaemia type I). According to these three major clinical presentations and according to the proper use of few screening tests (blood gases, glucose, ammonia, lactic acid, electrolytes, acetest), we propose a method of diagnosis which groups these children into five schematical syndromes: type I MSUD; type II organic acidaemias; type III; congenital lactic acidosis; type IVa, urea cycle defects; type IVb, non-ketotic hyperglycinaemia, sulfite oxidase deficiency, peroxisomal disorders; type V liver dysfunctions. Once the above classification has been made, sophisticated and specific investigations can be planned (amino acid chromatography, organic acid chromatography, enzymatic studies, etc).

Three patients affected by infantile Refsum disease are described with mental retardation, minor facial dysmorphia, chorioretinopathy, sensorineural hearing deficit, hepatomegaly, failure to thrive and hypocholesterolaemia. Initially, only an accumulation of phytanic acid was thought to be present. More recent findings showed a biochemical profile very similar to that found in classical Zellweger syndrome or neonatal adrenoleukodystrophy. Morphologically typical peroxisomes were absent in the liver. All three disorders are associated with multiple peroxisomal dysfunction. Because of these similarities pertinent clinical data of our three patients are compared with those of reported patients diagnosed as having infantile Refsum disease, neonatal adrenoleukodystrophy or Zellweger syndrome who survived for several years. Attention is drawn to the difference in severity of clinical features, ranging from infantile Refsum's disease to neonatal adrenoleukodystrophy and, finally, to Zellweger syndrome.

This review describes the transmission, clinical picture and immunological abnormalities of HIV infection in children in general, and the special problems of AIDS in African children. The review begins with a thorough introduction to the epidemiology of AIDS. Transmission to children generally involves vertical transmission by placental transfer or transmission of HIV via transfusion of blood and blood products, or by contaminated needles. Casual transfer is unknown, and only a few cases of transmission via breast milk are known. The clinical picture of HIV infection in infants and children differs from that in adults in 3 important aspects: earlier onset, different clinical presentation and existence of AIDS embryopathy. The average onset was 5 months of age. The most common symptoms in young children are chronic interstitial pneumonitis without demonstrable etiology, hepatomegaly, failure to thrive, adenopathy, diarrhea, oral or perineal thrush, eczema and thrombocytopenia. The common opportunistic infections are pneumocystis carinii pneumonia, cytomegalovirus, Epstein-Barr virus, Cryptosporidium diarrhea, pyogenic infections of the middle ear and gram-negative septicemia. Several infections seen in adult AIDS cases are rare in children: mycobacterium avium-intracellulare, toxoplasma gondii, hepatitis B, as well as Kaposi's sarcoma, malignant lymphoma and cardiac abnormalities. The AIDS embryopathy or HIV dysmorphic syndrome is characterized by immunological abnormalities, growth failure, and craniofacial dysmorphism, particularly microcephaly, prominent box-like forehead, hypertelorism, flattened nasal bridge, obliquity of the eyes, blue sclerae and patulous lips. AIDS in African children is extremely difficult to diagnose because of similarities between the presenting symptoms and those commonly seen in sick children there, many of whom are also immune compromised. Where serotesting is available, the picture is complicated by cross reaction between the test agents and some factor found in sera from malaria patients. Seropositivity in some areas is high, increased by the prevalence of transfusion and injection treatments. Diagnosis is made more difficult by lack of laboratory facilities and difficulties in follow-up for pediatric patients. The CDC definitions of AIDS and ARC, and the WHO/CDC definitions of AIDS are appended.

Cystic fibrosis (CF) is generally believed to be rare or nonexistent in Saudi Arabia. The aim of this report is to document the occurrence of CF in Saudi Arabia. Thirteen Saudi children were diagnosed as having CF, evidenced by typical clinical features and elevated sweat chloride concentrations (greater than 60 mmol/l). Duration of symptoms prior to diagnosis varied from 1 month-5 years (mean 23 months). The main clinical manifestations of the children were abdominal distention, failure to thrive, steatorrhoea, hepatomegaly, rectal prolapse and recurrent respiratory infections, often with Pseudomonas aeruginosa. In addition, eight patients with symptoms and a family history highly suggestive of CF, but without confirmatory sweat test results are presented. We hope that this report will increase the awareness of CF and ensure an earlier diagnosis of the disease in Saudi Arabia.

Perinatal transmission of human immunodeficiency virus is thought to occur in 25% to 50% of the offspring of infected women. Standard diagnostic methods do not permit identification of the infected newborns. To assess diagnostic methods and document the natural history of perinatal human immunodeficiency virus infection, 20 children born to human immunodeficiency virus-infected women were followed prospectively for 18 months by measuring antibody titer, Western blot profiles, and antigenemia, and the results were compared with clinical outcome. Endogenous synthesis of anti-human immunodeficiency virus IgG was demonstrated in 6 of the 8 infected children. Four children synthesized IgM against human immunodeficiency virus. Five had demonstrable p24 antigenemia. No significant differences between infected and noninfected children were noted at birth except drug withdrawal, which occurred more frequently in noninfected infants. The incidence of adenopathy, hepatomegaly, and neurologic and immunologic abnormalities in the infected children were compared with noninfected children. The distinguishing illnesses were the opportunistic infections, lobar pneumonia, and failure to thrive. Seven of the 8 infected children had human immunodeficiency virus-mediated disease by 1 year of age (Centers for Disease Control [Atlanta, Ga] P2 classification), and four had acquired immunodeficiency syndrome (Centers for Disease Control P2D). These studies offer an approach to diagnosis of human immunodeficiency virus infection in infants and document the natural history and possible outcomes of infected children.

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.

In order to study the long term outcome of hepatic glycogen storage diseases, a national retrospective inquiry gathered 76 patients older than 12 years. In adolescents and adults, hypoglycemia, failure to thrive, pubertal delay, hepatomegaly and metabolic disturbances are major in type I, intermediary in type III and mild in type "VI+IX". Spontaneous improvement of these symptoms is noted in older patients. Beside these classical signs, anemia, high blood pressure, renal failure and persistent hypercholesterolemia were reported in some type I glycogen storage disease and bad school and professional results in type III. The knowledge of these complications should lead to a better management of these patients.

A 3-month-old girl presented with anorexia, failure to thrive and drowsiness. She was mildly icteric with hepatomegaly and peripheral oedema. Disordered liver function tests were associated with the biopsy appearances of a giant cell hepatitis and with a Fanconi syndrome. At the age of 16 weeks she collapsed with profound hypoglycaemia. Fasting also provoked hypoglycaemia with lactic acidaemia. She became increasingly irritable and hypotonic and, although initially liver and renal function improved, she deteriorated and died of hepatocellular failure and septicaemia. A post-mortem revealed massive fatty degeneration of the liver. The activity of phosphoenolpyruvate carboxykinase in her cultured skin fibroblasts was 16% of controls. Her brother died at the age of 4 weeks of sudden infant death syndrome.

A four-month-old boy affected by glycogen storage disease type I is presented. The child suffered from hepatomegaly, lactic acidosis, fasting hypoglycemia and failure to thrive. He had repeated infectious and cyclic neutropenia. Immunoglobulin and chemotactic neutrophil motility was impaired. Liver biopsy showed increased amounts of glycogen in hepatic cells as assessed by morphological and biochemical grounds. The activity of glucose-6-phosphatase as well as other glycogenolytic enzymes was normal in the frozen liver. The aforementioned characteristics suggested the diagnosis of glycogen storage disease type Ib. The child was first treated by enteral continuous feeding and later on by frequent meals during the daytime and enteral continuous feeding during the night time, improving the hypoglycemia as well as the other biochemical and metabolic abnormalities.
