1. Mean daily nutrient intakes of 195 women in the first trimester of pregnancy were assessed by weighed dietary records. 2. In comparsion with recommended intakes for non-pregnant women aged 18-55 years (Department of Health and Social Security, 1969), more than two-thirds of the subjects were having insufficient energy, iron and cholecalciferol. Unsatisfactory intakes of other nutrients were not uncommon. In relation to recommended intakes for the second trimester (Department of Health and Social Security, 1969), all mothers were having insufficient cholecalciferol and more than 80% of mothers had unsatisfactory intakes of energy and Fe. 3. Intakes appreciably lower than those recommended were associated with the following factors: social classes III, IV and V; maternal age under 20 years; smoking ten or more cigarettes daily; vomiting on more than 3 d/week.

Four haematinic supplements--Slow-Fe, FGF, Ferro-Gradumet and Ferro-Grad tfolic--were prospectively studied in 103 healthy pregnant patients. Significant differences in the mean cell counts, haematocrit values, haemoglobin levels, iron-binding capacities and serum folate levels were noted. The changes paralleled the elemental iron present in the compount. In this series, side effects principally vomiting and constipation, were more frequent in the lower dose iron group. Form both the haematological status aspect and the lack of side effects, Ferro-Grad Folic and Ferro-Gradumet were superior to both FGF and Slow-Fe (old formulation).

Data on prenatal, labor and delivery, and postnatal medication exposure to neonates were collected. During an 11-week period, 100 neonates consecutively admitted to a hospital were studied. The pharmacist obtained a social and medication history from the mothers and reviewed maternal anesthesia records and the charts of the neonates. Fifteen definite and possible adverse medication reactions were detected in 13 neonates. The median number of different medications ingested prenatally was 4.7. The four most commonly ingested prenatal medications were vitamins (97%), iron preparations (90%), headache/pain/arthritis medications (68%) and antinausea/vomiting medications (40%). The most commonly used medications during labor and delivery were oxytocin (73%), meperidine (33%) and promazine (25%). The use of strong narcotics during this period produced neonatal respiratory depression in some cases. The four most commonly prescribed postnatal medications were vitamin K1 (100%), gentamicin (10%), ampicillin (8%) and Poly-Vi-Sol (6%). The maternal interview indicated that most mothers were unaware of the influence that many medications can play upon the fetus. It is recommended that the pharmacist conduct a maternal medication interview prior to labor and delivery.

The last 30 years have shown marked improvements in formula feeding of infants. A decrease in breast-feeding popularity and improved sanitary formula methods are responsible for increased use of formulas. Because an infant's growth rate is highest from birth to 1 year, nutritional adequacy of the diet is of vital importance. Necessary for evaluating an infant's formula are the following: 1) the formula should have essential nutrients but not in excess; 2) it should be readily digestible; and 3) there should be a reasonable distribution of calories derived from protein, fat and carbohydrates; digestibility of the fat source is important. Iron deficiency anemia, the most prevalent deficiency in infants, is remedied by the use of iron-fortified commercial formulas. The most effective nutritionally balanced milk is human milk. 2 reasons for other choices are infantile abnormal conditions which require therapeutic formulas or the mother's choice not to breast-feed. A comparison of cow's and human milk shows that the former has 3 times as much ash and protein (which alters digestibility) than normally found in the latter. Differences in casein or curd content triglycerides and percentage of carbohydrates are sufficient to render human milk more easily digestible and nutritionally complete than cow's milk. Standard formulas, on the other hand, nutritionally approximate cow's and human's milk by chemically altering casein proteins, replacing butterfat with vegetable oils and creating highly concentrated electrolyte replacements for electrolyte loss during diarrhea and vomiting. A wide variety of therapeutic formulas are employed for milk allergy, fat restrictions, congenital heart disease, low birth weight infants and phenylektonuria. Preparation of infant formulas include ready-to-feed, concentrated liquid and concentrated powder. Proper dilution in the latter 2 is stressed as is the absolute need for sterilization of all equipment used in formula preparation. The appropriate choice would be a formula that is well tolerated by the infant, conveniently stored and prepared, and within the family budget.

This study examined the relationship between gastrointestinal (GI) symptoms and dietary intake in triathletes. Fifty-five male triathletes (age 31 +/- 6 yrs) were surveyed regarding the most recently completed half Iron Man triathlon. Questions were asked regarding GI symptoms and dietary intake. Fifty-two percent complained of eructation and 48% of flatulence. Other symptoms were abdominal bloating, vomiting urge, vomiting, nausea, stomachache, intestinal cramps, and diarrhea. More symptoms occurred while running than at other times. All individuals who had eaten within 30 min of the start vomited while swimming. Fat and protein intake was greater in those who vomited or had the urge to vomit than in those without these symptoms. Of the former, 93% had consumed a hypertonic beverage. Forty percent of those who drank a hypertonic beverage and only 11% of those who drank an iso- or hypotonic beverage had severe complaints. Four of five individuals with stomachache had consumed a strongly hypertonic beverage. All subjects with intestinal cramps had eaten fiber-rich foods in the prerace meal; only 10% of those without cramps had done so.

Limited reports exist regarding acute iron intoxication during pregnancy. The maternal and fetal effects of accidental or deliberate ingestion of large amounts of iron may be catastrophic. A case report of acute iron intoxication, management strategies, and a review of the literature are presented. The cornerstones of effective therapy are aggressive management with emesis induction or gastric lavage, bicarbonate instillation, vigorous intravenous hydration, and chelation therapy with deferoxamine.

Ferrets were exposed to gamma rays (60Co), fission neutrons, high-energy electrons (18.5 MeV) or iron particles (56Fe, 600 MeV/amu) in order to establish the dose-response relationships for emesis following exposure to different types of radiation. The results showed that the mean effective doses (ED50s) for iron particles (35 cGy) and neutrons (40 cGy) were similar. High-energy electrons were the least effective radiation, with an ED50 of 138 cGy. Gamma rays, with an ED50 of 95 cGy, showed an intermediate effectiveness. The results suggest that the relative effectiveness of different types of radiation generally increases with an increase in linear energy transfer (LET), although LET is not completely predictive of relative behavioral effectiveness.

The author relates her experience in Benin during a 3 and 1/2 year tenure as a nurse under the aegis of the German Development Agency. In Malanville, she was responsible for starting the operating room, caring for hygiene, sterility, and the related training of domestic staff. A septic and aseptic operating room was set up along with a storage room for instruments, a sterilization room, and a changing room. For the operating and surgical station, the following personnel were available: 2 nurses with 3 years of training, 1 nurse with 2 years of training, and 3 orderlies without training. A nurse with 3 years of training was assigned to the author to carry on the project after her departure. The standard of operating care was very low. It took a month to teach the staff what was not sterile. There was a even problem with putting on sterile gloves which required an exercise in patience. There were an average of 5 relatives per patient taking care of the patient and cooking. The undernutrition center for infants had 6 beds with 2 German nurses who administered Bacillus Calmette-Guerin (BCG), diphtheria, polio, and tetanus vaccinations. Their activity was strengthened by nutrition counselling and plans for underweight and malnourished children. Abrupt weaning that resulted in harmful diarrhea and vomiting was prevalent. Clinical signs of marasmus and kwashiorkor were frequent. In the middle of 1990, AIDS educators informed students of the public school as well as registered prostitutes about condom use. In the hospital, there were about 900 births per year, and women were asked to follow recommendations for prenatal care, especially to achieve anemia prevention by getting iron tablets. They were urged to deliver in the clinic, not at home assisted by untrained midwives. Oxytocin and syntometrin were available as was a hand-driven, vacuum evacuation pump. This experience made a lasting impression on the author who has resolved to go to another developing country to train traditional birth attendants in midwifery.

The pharmacology, pharmacokinetics, clinical efficacy, adverse effects, and dosage and administration of succimer when used for the treatment of lead poisoning are reviewed. Succimer is an orally active, heavy-metal chelating agent that forms stable, water-soluble complexes with lead; it also chelates other toxic heavy metals, such as arsenic and mercury. It is a designated orphan drug that is indicated for the treatment of lead poisoning, specifically in children with blood lead concentrations higher than 45 micrograms/dL. Succimer reverses the adverse metabolic effects of lead on heme synthesis while increasing urinary lead output without adversely affecting essential mineral excretion at the recommended dosage regimen. The rebound in lead concentrations that can occur after short courses of chelating therapies (caused by redistribution of lead from bone stores) may require frequent and multiple courses of chelation therapy. The most common adverse effects reported in clinical trials of succimer in children and adults were nausea, vomiting, diarrhea, appetite loss, and loose stools; these effects may be related to the drug's unpleasant mercaptan odor. There are no known drug interactions between succimer and other drugs, including iron supplements, although data are limited. The recommended initial dosage in children is 10 mg/kg or 350 mg/sq m every eight hours for five days. The dosage is then reduced to 10 mg/kg or 350 mg/sq m every 12 hours for an additional two weeks. Clinical studies indicate that succimer is relatively selective for lead and effectively lowers blood lead concentrations. Although clinical experience is limited, an oral lead chelator may offer advantages over currently available agents.

An 11-month-old, 11-kg infant presented to the emergency department after ingesting 130 to 150 mg/kg of elemental iron. Emesis was induced twice and the child was lavaged throughout a 4-hour period with some tablet return. An abdominal radiograph after gastrointestinal decontamination showed at least 16 whole iron tablets remaining in the stomach. Serum iron drawn 2 hours postingestion was 46.7 mumol/L. Blood glucose was 7.7 mmol/L and white blood count was 21,800 mm3. Despite a second lavage 8 hours postingestion, a large number of whole tablets were visualized in the stomach per radiograph. Whole bowel irrigation with polyethylene glycol electrolyte lavage solution (Golytely, Braintree Laboratories, Inc, Braintree, MA) was begun via nasogastric tube 14 hours after the ingestion. Serial abdominal radiographs showed tablet movement out of the stomach within 4 hours after initiating whole bowel irrigation. This case demonstrates the safety and efficacy of WBI in an infant when conventional gastrointestinal decontamination has failed.
