A 3-yr-old boy was investigated for numerous episodes of fatigue, irritability, pallor, and sweating, which began at 11 mo of age, when he had an episode of symptomatic hypoglycemia with ketonuria. He had euphoria, mental confusion, drowsiness, nausea, and vomiting 1-5 hr after oral administration of glycerol in doses of 0.5-1.0gm/kg. Orally administered MCT (1 gm/kg) had similar effects. On one occasion, oral glycerol also provoked hypoglycemia, as had a 16 1/2 hr fast. Intravenously administered glycerol (0.09 gm/kg) induced an immediate loss of consciousness from which he recovered spontaneously after 30 min; there were no changes in blood glucose values. Intravenously administered fructose (0.25 gm/kg) was tolerated normally. Leukocytes showed normal activities for FDPase, glycerol kinase, and glycerol phosphate dehydrogenase. The restriction of dietary intake of fat has been associated with a marked improvement in physical and mental activities. These observations suggest a unique, yet undifined intolerance to glycerol, which suggest caution in the diagnostic use of glycerol in the investigation of hypoglycemia as well as in the therapy of increased intracranial or intraocular pressure.

It is today's general medical opinion that children's diabetes mellitus was uncommon in the past. It was generally admitted at that time the initail stages were so sudden as to make difficut its early diagnosis. It's increased incidence is at present an alarming truth; however, a parallel increase of diabetic coma or of mulminant types has rather dropped. Diabetes may be diagnosed by just considering the main symptoms at the onset which are polydipsia, polyuria and weight loss. If an early diagnosis is not made, acidosis (abdominal pain, nausea, vomiting) may appear within a few days or weeks followed by coma (Kussamul's acidotic respiration and dehydration). Coma may be avoided by an early diagnosis and a life may be saved. It must be stressed that an important percentage of children and adolescents show a slow and gradual evolution (week or months) of their diabetes: gradual weight loss, sometimes with noticeable polyphagia, occasional enuresis, but without other associated symptoms. Asymptomatic, intermittent glucosurias are also frequent; they vary in magnitude an almost always they appear without ketonuria and with fasting normal glycemia. According to our experience they may precede in weeks or months the clinical manifestations of the disease. Postprandial glycemia is a sure diagnostic resource; it is of greater trustworthines than fasting glycemia; therefore we advise it as a routine diagnostic procedure which we recommend widely. In uncertain situations, the oral glucose tolerance test is advisable.

A new case of propionic acidemia is presented, paying special attention to the early symptoms of this disease, such as increased drowsiness, muscular hypotonia, poor feeding, hypothermia, metabolic acidosis, ketonuria and vomiting. Investigation by gas chromatography (GC) and gas chromatography-mass spectrometry (GC-MS) revealed the excretion of fairly high amounts of 2-methyl-3-oxovaleric acid, a condensation product of two molecules of propionyl-CoA, as well as the known pathological metabolites such as propionic, 3-hydroxypropionic and methylcitric acids. Among the post mortem findings the histological studies of the liver were the most remarkable.

The efficacy of fixed dose PGE2 (prostaglandin E2) in inducing labor was studied in 40 multiparous patients. Low amniotomy was performed, and 1 tablet of 6.5 mg PGE2 was given orally in the absence of uterine activity after 30 minutes, and hourly thereafter until the patient delivered. Successful induction was defined as the establishment of effective uterine contractions and cervical dilatation within 12 hours of amniotomy. Indications for induction are postmaturity (n=15); pre-eclampsia (n=10); essential hypertension (n=6); weight loss (n=4); bad obstetric history (n=2); and others (n=3). 38 patients (95 percent) had successful labor induction, with 37 delivering vaginally within 18 hours of amniotomy and 1 delivering by Cesarian section because of fetal distress. In the remaining 2 patients, labor did not commence within 12 hours and consequently necessitated intravenous oxytocin. Mean amniotomy-delivery interval was 7.53 hours. Maternal side effects included vomiting (12.5%); diarrhea (5%); pyrexia (15%); ketonuria (22.5%); and postpartum hemorrhage (12.5%). There were no apparent fetal side effects. Advantages of oral PGE2 for labor induction include: 1) ease of administration; 2) increased patient acceptability; 3) greater convenience for medical and nursing staff; 4) absence of complications associated with intravenous infusion such as sudden changes in infusion rate, air emboli or occasional pyrogen reactions. Advantages of using a low fixed dose are: 1) excessive administration and subsequent uterine hypertonus are less likely to occur; 2) low incidence of vomiting/diarrhea; and 3) absence of uterine hypertonus and apparent fetal side effects.

Propionyl CoA carboxylase deficiency was found in a 7-month-old boy who presented with attacks of vomiting, anorexia, weight loss, weakness, and hypotonia. He failed to thrive and had generalized seizures. He had propionic acidemia and hyperglycinemia; these are the manifestations of the ketotic hyperglycinemia syndrome. However, ketonuria was not a consistent part of his clinical picture, and he had at least two episodes of acute overwhelming illness, the latter one fatal, in which ketones were never found in the urine. Large amounts of pyrrolidone carboxylic acid were found in body fluids.

A case of isovaleric acidemia appearing as diabetic ketoacidosis with acute encephalopathy and pancytopenia was reported. A three-year-old male patient, with mild psychomotor retardation, had recurrent bouts of acute encephalopathy and pancytopenia after episodes of upper respiratory infection. At admission, he had vomiting associated with dehydration, acidosis, ketonuria, coma and a pungent, rather unpleasant odor. Laboratory features included hyperglycemia, hyperammonemia, hyperamylasemia, hypocalcemia, neutropenia, thrombocytopenia and subsequent anemia. Urine organic acid profiles showed profuse amount of 3-beta-hydroxyisovaleric acid (295 mg/ml) and isovalerylglycine (616 mg/ml) by gas chromatography-mass spectrometry. Levels of amino acids in the serum and urine were normal. The patient received treatment with rehydration and insulin, with rapid improvement. After the acute illness, blood glucose levels returned to normal. The patient was doing well on a low-protein diet in recent 3 months.

We reviewed retrospectively a cohort of 80 patients with hyperemesis gravidarum hospitalized between 1976 and 1986 for the presence of abnormal liver enzymes and ketonuria. Thirteen (16%) had abnormal liver enzymes, generally less than four times the upper limit of normal. In this group, hyperemesis gravidarum began at the 14th week of pregnancy as compared to the 6th week in the normal enzyme group (p less than 0.01). Both groups were similar with regard to age, number of children and pregnancies, and duration of vomiting. Ketonuria was significantly more severe (p less than 0.01) in the abnormal enzyme group, implying a more severe state of starvation and dehydration. The correlation coefficient between the degree of ketonuria and level of liver enzymes was low for alkaline phosphatase (r = 0.18), GPT (r = 0.15), and GOT (r = 0.28). The concept that dehydration and starvation are important factors for the induction of liver cell injury is supported by our data. Lack of correlation between the degree of ketonuria and liver enzyme levels is suggestive of other mechanisms (hormonal, genetic) that may interact to produce transaminasemia.

The metabolic response to human growth hormone (HGH) was studied in five obese subjects in the fed state and during prolonged (5-6 wk) starvation. In the fed state (three subjects), HGH induced an elevation in basal serum insulin concentration, a minimal increase in blood and urine ketone levels, and a marked reduction in urinary nitrogen and potassium excretion resulting in positive nitrogen and potassium balance. In prolonged fasting (four subjects), HGH administration resulted in a 2- to 3-fold increase in serum insulin which preceded a 50% elevation in blood glucose. Persistence of the lipolytic effects of HGH was indicated by a rise in free fatty acids and glycerol. The response differed markedly from the fed state in that blood beta-hydroxybutyrate and acetoacetate levels rose by 20-40%, resulting in total blood ketone acid concentrations of 10-12 mmoles/liter, ketonuria of 150-320 mmoles/day, and increased urinary potassium loss. The subjects complained of nausea, vomiting, weakness, and myalgias. Despite a 50% reduction in urea excretion during HGH administration, total nitrogen loss remained unchanged as urinary ammonia excretion rose by 50% and correlated directly with the degree of ketonuria. It is concluded that in prolonged starvation (a) HGH may have a direct insulinotropic effect on the beta cell independent of alterations in blood glucose concentration, (b) persistence of the lipolytic action of HGH results in severe exaggeration of starvation ketosis and interferes with its anticatabolic action by necessitating increased urinary ammonia loss, and (c) failure of HGH to reduce net protein catabolism in starvation suggests that this hormone does not have a prime regulatory role in conserving body protein stores during prolonged fasting.

Two cases of propionicacidemia are reported. The first patient was a child aged 16 months with psychomotor retardation, severe disturbances of wakefulness, and vomiting; the second case concerned a new-born baby with metabolic acidosis and neurological disorders. In both cases the diagnosis of propionicacidemia was made after the discovery of ketonuria, and raised blood ammonia and glucose levels. Appropriate dietary measures led to great improvement in the first case, and nearly normal psychomotor development in the second case at 7 months of age. Problems related to biotin sensitivity, leucine intolerance, and raised blood ammonia levels are discussed.

Metabolic alkalosis is regarded as the "classical" electrolyte abnormality occurring with hypertrophic pyloric stenosis (HPS) but recent experience suggests that atypical electrolyte findings frequently occur and delay establishing the correct diagnosis. The records of 65 infants with HPS treated by pyloromyotomy during the past 4 years were reviewed to determine the serum electrolytes at the initial presentation. The four study groups formed included 8 (12.3%) patients in group A with serum bicarbonate (HCO3) below 18 mEq/L (mean 15.7 +/- 0.5 mEq/L); 19 (29%) in group B with HCO3 between 18 and 25 (22.9 +/- 0.3); 22 (33.8%) in group C with HCO3 between 25 and 30 (27.0 +/- 0.3) and 16 (24.6%) in group D with HCO3 over 30 (34.0 +/- 0.9). Established values for normal HCO3 in neonates is 20.1 +/- 2.5 (mean +/- SD). The mean values in group D for HCO3, potassium (4.0 +/- 0.18 mEq/L), and chloride (88.75 +/- 2.15 mEq/L) were each significantly different (p less than 0.001) from determinations of similar electrolytes in other groups. The duration of vomiting in group D of 10.5 +/- 1.3 days is almost double the time (p less than 0.001) in group A, and was associated with more severe dehydration, predominantly acid urine (pH less than 6), and ketonuria as compared to other groups. No significant difference in other demographic characteristics including the age at presentation, the gestational age, sex distribution, or types of formula used was observed. The results of the study emphasize that serum electrolytes in early HPS may be normal, that HCO3 is significantly lower than established normals for older children, and that the effects of hydrogen-ion loss elevating the serum HCO3 precedes alterations in other serum electrolytes.
