Certain common but seldom recognized clinical features of renovascular hypertension peculiar to infancy are emphasized in this communication from the observations made in a 9-month-old infant. Failure to thrive, extreme irritability, hypotonia, anorexia, vomiting, diarrhea, respiratory distress, and congestive heart failure are common clinical findings. Unless the physician is aware of this symptomatology or blood pressure is routinely obtained in all infants, the condition is likely to be missed. Renovascular hypertension is malignant and carries a high mortality but if diagnosed early may be cured by surgical intervention.

The role of ions and cell membrane function in the pathogenesis of benign and malignant hypertension was investigated in spontaneously hypertensive rats (SHR). Ten-week-old male SHR (n = 50) and SHR treated with deoxycorticosterone acetate (DOCA; n = 70) and 1% NaCl drinking water were studied weekly for 14 weeks. Malignant hypertension developed only in DOCA-salt SHR and was characterised by severe hypertension, failure to thrive and renal fibrinoid necrosis. Fourteen DOCA-salt SHR and one SHR died. Extracellular (serum) and intracellular (erythrocyte and muscle) Na+, K+, Mg2+, Ca2+ and muscle membrane Na+,K(+)-adenosine triphosphatase (ATPase), Ca(2+)-ATPase and Mg(2+)-ATPase were measured at various stages in the development of malignant hypertension. Three developmental phases were defined: benign, premalignant and malignant. DOCA-salt SHR showed persistent hypokalaemia. In the benign phase, there were no differences in Na+, Mg2+ and Ca2+ between SHR and DOCA-salt SHR. In the premalignant phase, serum and erythrocyte Mg2+ and ATPase activity were significantly lower in DOCA-salt SHR compared with SHR. During the late premalignant and malignant phases, intracellular Ca2+ and Na+ were significantly higher in the DOCA-salt SHR compared with SHR. In view of these findings, the abnormalities in DOCA-salt SHR during the early phases of blood pressure elevation could be contributory factors to the development of malignant hypertension.

Thirty six symptomatic hospitalized hypertensive children were evaluated for clinical profile and etiology. They were divided into two groups of 23 and 13 patients, respectively of chronic persistent hypertension and acute transient hypertension. Headache, failure to thrive, dyspnea and edema were common clinical features. Renal parenchymal pathology was the commonest etiology in both groups with a tubulo-interstitial pathology being more common amongst chronic hypertensives and acute glomerulonephritis in acute transient hypertensives. Essential hypertension was uncommon, found in only two patients with chronic hypertension reflecting probably an asymptomatic status of most patients with essential hypertension.

Violent shaking causes severe injury in infants, but the diagnosis of shaken baby syndrome is often difficult to make because of the lack of obvious external signs. Consultations by other specialists may not be helpful, since the findings of most organ systems, taken in isolation, are usually nonspecific. Shaken baby syndrome should be considered in infants presenting with seizures, failure to thrive, vomiting associated with lethargy or drowsiness, hypothermia, bradycardia, hypertension or hypotension, respiratory irregularities, coma or death. Shaken babies are usually less than one year old, and most are under six months of age. Head injury (notably subdural hemorrhage) and retinal hemorrhages are the hallmarks of the syndrome.

Recommendations for weaning have been based on empiric practices and observations of physiologic development. Estimates of nutritional requirements mimic those of the preweaning infant, adjusted for a slower growth rate. Concern for the onset of deficiency states (e.g., obesity, failure to thrive, atherosclerosis, hypertension) may provide scientific bases for nutritional recommendations during weaning.

The natural history of Williams syndrome, including medical complications, growth patterns, and problems in adulthood, was investigated. A growth pattern characterized by delay in the first 4 years of life, catch-up growth in childhood, and low ultimate adult height was found. Despite multiple medical problems in infancy, including feeding problems, failure to thrive, colic, and otitis media, mean age at diagnosis was 6.4 years. Developmental disabilities and cardiovascular disease were the major concerns in childhood. The older children developed progressive joint limitation and hypertonia. Adult patients were handicapped by their developmental disabilities. Hypertension, and gastrointestinal and genitourinary problems occurred frequently. Independent living and competitive employment were limited less by the individual's physical problems than by the psychologic and adaptive limitations. Williams syndrome is a progressive disorder with multisystem involvement.

Idiopathic infantile arterial calcification was diagnosed in a 2 week old infant with failure to thrive associated with neurological, renal and cardiac signs. Therapy with diphosphonate resulted in a complete resolution of vascular calcifications. At the age of 2 years the child is doing well but requires medical treatment for arterial hypertension.

Records of all children presenting with urinary calculi in the period 1972-86 were reviewed in order to detail clinical features, laboratory and radiographic findings and treatment. Of a total of 85 children, 59 were Aboriginal and 26 were Caucasian. The features of urolithiasis differed between these groups. In the Aboriginal patients, calculi consisted mainly of uric acid and urates. Important clinical characteristics of this group included a young age at presentation (median = 2.1 years) and frequent presentation with failure to thrive. Calculi were commonly located in the upper urinary tract and most required surgical removal. Documented sequelae included renal scarring and hypertension. Caucasian children presented at a later age (median = 10.5 years), frequently with abdominal pain, and most calculi were associated with an underlying urological or metabolic abnormality.

A 3 year old Chinese girl with watery diarrhoea, abdominal distension and hypokalaemia due to a thoracic paraspinal vasoactive intestinal peptide (VIP) secreting ganglioneuroma is reported. The pre-operative serum VIP was 314 pmol/l (normal less than 30). Her diarrhoea stopped after the removal of the tumour. The VIP was 14 pmol/l 6 months post-operatively. Review of the 19 reported cases in children with documented elevated serum VIP showed that many of the cases presented with watery diarrhoea for prolonged duration before the diagnosis was made. Earliest age of onset was 2 weeks of age. The male to female ratio was 9:10. Ganglioneuroma and ganglioneuroblastoma were the commonest tumours. Pancreatic non-beta cell hyperplasia and neurofibroma were also reported. Location of the tumour was variable: neck, chest or abdomen. Increased urinary catecholamine excretion was reported in 50% of the cases. Abdominal distension, flushing, episodic hypertension and failure to thrive were the other associated features.

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.
