A case of central pontine myelinolysis (CPM) following rapid correction of hyponatremia was reported and literatures were reviewed. The case was 61-year-old nonalcoholic female who had taken an operation of craniopharyngioma 23 years ago. Fifteen years later, she received re-operation for the recurrent tumor, followed by replacement therapy of corticosteroid and clofibrate. She was otherwise well until two weeks before entry, when she noticed abrupt onset of high grade fever, nausea,
vomiting
and general malaise. She was admitted to an emergency hospital because of weakness, disorientation and a slight impairment of consciousness, but she was able to speak and to take some food per os. Laboratory studies disclosed urinary tract infection and showed a serum sodium level of 117 mEq/l,
potassium
2.9 mEq/l, a serum osmolarity 232 mO sm/l and urine osmolarity 141 mEq/l. She was diagnosed to have an exacerbation of adrenal insufficiency with hyponatremia and hypotonic dehydration triggered by urinary tract infection. Intravenous administration of vitamin B complex, electrolytes including KCL, 5% glucose solution and physiological saline with a large amount of corticosteroid was performed aggressively. Serum sodium concentration was raised to 161 mEq/l in two days, and the increased level had been maintained more than five days, resulting in coma and flaccid quadriplegia. During this period, there was no episode of hypotension, hypoglycemia, hypoxia nor hepatic failure which could have caused brain damage.(ABSTRACT TRUNCATED AT 250 WORDS)

Twelve taste repellents and 3 oral emetics were tested. The taste repellents were capsaicin, capsicum, oleoresin, sucrose octaacetate, quinine tonic, quassia wood extract, vanillamide, horseradish extract, caffeine, pepperoni enhancer, acorn extract, and commercially available bitter and hot flavors. The emetics tested were: antimony
potassium
tartrate, apomorphine, and copper sulfate. Intake of a 20% sucrose solution by Beagles was significantly depressed by addition of vanillamide at concentrations greater than 0.001%, by capsicum and capsaicin at concentrations greater than 0.01%, and by horseradish extract, pepperoni enhancer, and a commercially available hot flavor at concentrations greater than 0.1%. Antimony potassium tartrate, when added to the 20% sucrose solution at a concentration of 0.1%, produced
emesis
as did apomorphine at a concentration of 0.005% and copper sulfate at 1%. When the emetic antimony
potassium
tartrate was combined with vanillamide in a 20% sucrose solution, intake was reduced to less than 20 ml, and
vomiting
occurred within 15 minutes. Capsaicin (0.02%) inhibited intake of ethylene glycol to less than the lethal dose in 5 dogs tested. Incorporation of such taste repellents and/or emetics into potentially poisonous substances would reduce accidental poisoning of animals and children.

The main purpose of this work was to study changes in the balance of fluids, electrolytes and blood metabolites in neonatal piglets with severe transmissible gastroenteritis. Six two day old conventional piglets were infected with transmissible gastroenteritis virus while six others were used as normal controls. Blood samples were collected in heparin when the infected piglets were moribund. The following variables were measured: packed red cell volume, total plasma protein and bicarbonate, blood pH, blood urea nitrogen and plasma glucose, creatinine, chloride, inorganic phosphorus, sodium,
potassium
, magnesium and calcium.
Vomiting
and diarrhea appeared 12 to 24 hours postinoculation in the infected piglets and they were moribund one or two days later. Before becoming moribund, most of the piglets fell rapidly into a lethargic and comatose state. The most evident changes in their blood variables were an increase in packed cell volume, total protein, blood urea nitrogen, phosphorus and magnesium levels and a decrease in pH and bicarbonate concentration as well as a severe hypoglycemia. The results suggest that severe hypoglycemia coupled with metabolic acidosis and dehydration might be an important factor contributing to the high mortality rates caused by transmissible gastroenteritis in neonatal piglets. The hypoglycemia results from a combination of the inadequate glucose metabolism inherent to neonatal piglets and the acute maldigestion and malabsorption resulting from the diffuse and severe villous atrophy induced by the virus.

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.

We evaluated the relationship of ritodrine concentration to several maternal variables and to fetal heart rate in 17 women who received the drug for inhibition of preterm labor. Ritodrine was measured by high-performance liquid chromatography with electrochemical detection. Ritodrine increased maternal and fetal heart rate and decreased serum
potassium
in a dose-related manner, but wide variability was noted between patients and within individual patients. Tachyphylaxis of the maternal heart rate response to continuing treatment with ritodrine was seen in at least seven women. Maternal blood pressure, serum glucose concentration, and frequency of uterine contractions were changed by ritodrine treatment, but the changes in these variables were not closely correlated to the concentration of ritodrine (r less than or equal to 0.30 in all cases). The maximal infusion rate and the concentration of ritodrine in maternal serum after 4 hours of treatment were significantly (p less than 0.001) correlated with the frequency of uterine contractions prior to treatment. Successful inhibition of labor was achieved with serum concentrations of 15 to 31 ng/ml in 10 of 17 women; in six of the other seven women, labor could not be inhibited in spite of serum concentrations of 90 to 146 ng/ml. Side effects, such as hypotension,
vomiting
, chest discomfort, and shortness of breath, were most commonly observed when the infusion rate and concentration of ritodrine were increasing.

A fatal case of oral ingestion of
potassium
dichromate is presented. Following an initial presentation of abdominal pain and
vomiting
, the patient had a rapid progression to coma with the development of methemoglobinemia, coagulopathy, gastrointestinal hemorrhage, and respiratory distress syndrome. A blood concentration of chromium on admission was 5,800 mcg/dL, 80% of which was found to be in the intracellular fraction. Supportive treatment was also initiated as a four-hour period of hemodialysis followed by a one-hour period of charcoal hemoperfusion. Neither of these treatment modalities was found to significantly remove chromium from whole blood and neither seemed to affect the progression or outcome of this intoxication. We conclude that the ingestion of
potassium
dichromate is highly toxic and may rapidly lead to death. Hemodialysis and charcoal hemoperfusion appear to have little role in the management of chromium intoxication.

In 1980, 104 infants with seven to 15 percent dehydration due to severe diarrhea and
vomiting
were hospitalized in Tehran and treated in two separate phases, deficit therapy and maintenance therapy, using two isotonic oral solutions. For deficit therapy, solution A (sodium 80,
potassium
20 mmol/l) was administered at a rate of 40 ml/kg per hour until all signs of dehydration disappeared. For maintenance therapy, solution B (sodium 40,
potassium
30 mmol/l) was given sip by sip at a rate of about 250 ml/kg per 24 hours until diarrhea stopped. Intravenous fluids were not used, even in severe dehydration and shock. The efficacy and safety of this regimen were confirmed by rapid and successful rehydration and correction of electrolyte abnormalities present on admission.

21 patients who underwent maxillofacial surgery received daily 6-8 packets of the instant formula diet Fresubin (2,100-2,800 kcal = 8,790-11,720 J). In 1 patient nutrition with Fresubin had to be interrupted due to
vomiting
. Under nutrition with Fresubin, mean body weight decreased significantly by about 3.5 kg. Serum electrolytes, blood gases, pH, base excess, serum-urea-nitrogen and creatinine, albumin content, serum transaminases, glucose content, hemoglobin and hematocrit did not show any significant change. It was evident that the sodium and
potassium
content of Fresubin was not high enough to guarantee normal serum values. In 8 of 21 patients
potassium
had to be substituted parenterally. Concentrations of lipids and triglycerids increased during nutrition with Fresubin and became elevated over normal values without statistic significance.

One of the major factors in the development of severe protein-energy malnutrition (PEM) is infection, such as diarrhea, upper respiratory infection, and malaria. Social and environmental factors include family size, access to land and occupation of parents, and exposure of rural populations to urban centers. Breast milk has been shown to play a role in the prevention of infections; however, the mother must be well-nourished to provide the optimum product. Traditional foods available to rural children in most developing countries are difficult to digest and low in energy and protein and inadequate nutritional education prevents the inclusion of good protein sources in children's diets. Severe PEM, called marasmus and kwashiorkor is indicated by wasting of muscles, absence of subcutaneous fat, wrinkled skin, thin and sparse hair, and weakness. The basic treatment for severe PEM is dietary. Treatment of kwashiorkor and marasmus is divided into 3 stages: 1) attending to acute problems, 2) restoring nutritional balance, and 3) ensuring nutritional rehabilitation. Care must be taken to ensure a minimum daily intake of 3-4 gm of protein and 120-150 Kcal of energy/kg of body weight. There must be, in addition, replacement of vitamin A, zinc,
potassium
, magnesium, and iron. An initial regimen which has been advocated is based on dry skim milk, sugar, and vegetable oil, divided into 6-12 feedings/day, which prevents
vomiting
. It is not necessary to remove lactose from the diet, and other animal protein sources such as meat and meat extracts are also well accepted. Soy and vegetable protein have been used successfully. In treating mild and moderate PEM it is important to ensure the intake of these food supplements by the child and to avoid a major substitution effect in the household diet. It is crucial for the physicians, nutritionists, public health workers, and educators to convince parents about the safety of using foods that are fed only to adults and older children. In addition nutritional and health education must not be restricted to the rehabilitation of the child but the prevention of nutritonal deterioration of the entire family and sometimes to the entire community.

In the US oral glucose electrolyte solutions have been marketed for over 30 years for the treatment of infantile diarrhea. Recently, oral solutions have been widely used instead of intravenous fluids for treatment of dehydration from diarrhea, especially in developing countries, where diarrhea is a major cause of death in infants and young children and facilities for intravenous fluid replacement are limited or unavailable. The high concentrations of glucose and other carbohydrates in older preparations may make the diarrhea worse. The use of 2-2 1/2% glucose, as in "Infalyte, Pedialyte R.S." and the World Health Organization (WHO) solution avoids the osmotic effect of unabsorbed glucose, makes the taste tolerable, and promotes coupled absorption of sodium from the intestine. Replacement solutions for fluid loss due to diarrhea should also contain about 20 mEq/L of
potassium
because diarrhea invariably results in a substantial loss of
potassium
. Although homemade mixtures of glucose electrolyte solutions and commercial powders that require dilution are less costly than ready to use commercial solutions, errors in mixing or diluting occur often and can have serious consequences. For rehydration after volume depletion, the sodium concentration of the replacement fluid should be between 50-90 mEq/L, regardless of the cause of the diarrhea, patient's age, or the serum sodium concentration. For early treatment of diarrhea to prevent dehydration or for maintenance of hydration after parenteral fluid replacement, 90 mEq/L of sodium is acceptable for adults and children, but may not be appropriate for infants who have a higher insensible water loss. When diarrhea in infants is not caused by cholera, some consultants prefer to use more dilute fluids that contain 50-60 mEq/L of sodium. When circulatory insufficiency (10-15% weight loss), severe
vomiting
, inability to drink, or severe gastric distention is present, parenteral fluid replacement is indicated. With 5-8% acute weight loss, oral rehydration alone is often successful. Infants should be offered frequent small amounts of rehydration solution, aiming for an intake of about 150 ml/kg in the 1st 24 hours, 1/2 in the 1st 8 hours, if possible.
