The data of 16 children who died while receiving valproate (VPA) therapy in West Germany were analyzed. Five were normally developed, 5 were receiving VPA-monotherapy, and only 2 patients were aged less than 3 years. The first clinical symptoms of impending hepatotoxicity usually included nausea, vomiting, and apathy; pathologic laboratory tests reflected liver failure. Liver histology revealed microvesicular steatosis, cell necrosis, and bile duct proliferation of varying degree. An abnormal metabolite, 4-ene-VPA, was detected in all examined patients (six of six) and persisted after drug withdrawal. The pathogenesis of fatal liver failure during VPA treatment remains unknown. World-wide, approximately 100 fatalities have been reported in relation to VPA treatment. More than 90% were aged less than 20 years, 95% developed their first symptoms within the first 6 months of treatment, and 16 were treated with VPA alone. Since it is difficult precisely to define a group at risk for fatalities with VPA, careful clinical and laboratory monitoring with a special focus on vomiting and apathy, liver enzymes, and coagulation tests seem mandatory during the first 6 months after introduction of VPA. Taking into account the considerable number of fatalities during VPA treatment, the indication for its use requires careful reevaluation.

Of 61 cases of ibuprofen overdosage reported consecutively to the Rocky Mountain Poison and Drug Center from September 1985 through April 1986, 16 were excluded because of incomplete follow-up or concurrent medication ingestion. A toxic reaction developed in 7 (16%) of the remaining 45 patients. Nausea, vomiting, abdominal cramps, mild central nervous system depression, coma, tachycardia, apnea, metabolic acidosis with or without respiratory alkalosis, hematemesis, and oliguric renal failure were noted. Two of six adults had a toxic reaction, and one died. Among pediatric patients, 5/39 (13%) had a toxic reaction. Of patients whose ibuprofen ingestion was less than 104 mg per kg, none became ill. All patients in whom the time of ingestion was known (six of seven) and who had a toxic reaction did so within four hours of ingestion. An ibuprofen overdose, although usually benign, can occasionally produce serious toxicity.

During a 5-month period, 513 stool samples submitted to the enteric laboratory at the University Hospital of the West Indies were examined for Cryptosporidium. Oocysts were detected in 4.9% of all stools, 7.3% of diarrhoeal stools, 19.5% of stools from malnourished children and 23.7% of stools from malnourished children with diarrhoea. Cryptosporidium was the sole pathogen detected in all 25 positive stools, and was the second most frequent enteric isolate. All cases of cryptosporidiosis occurred in children less than 2.5 years of age. All 15 malnourished children were admitted to hospital where they presented with dehydration (87%), vomiting (93%), fever (100%) and diarrhoea which lasted an average of 15.3 days. Two of these children died. In contrast, dehydration (20%), vomiting (40%) and fever (50%) were less common and diarrhoea less protracted in well-nourished children, four of whom were admitted to hospital. This preliminary report suggests that cryptosporidial gastroenteritis presents with increased frequency and severity in malnourished compared with well-nourished Jamaican children.

In clinical descriptions of human plague, fever and tender lymphadenitis are emphasized and gastrointestinal manifestations are rarely mentioned. A review of 71 human plague cases showed that gastrointestinal symptoms occurred commonly (57%). Vomiting (39%) was the most frequent symptom, with nausea (34%), diarrhea (28%) and abdominal pain (17%) occurring less often. Physicians treating patients who reside in or have recently visited plague-endemic areas should include plague in the differential diagnosis in the presence of gastrointestinal symptoms and fever.

A prospective case-control study of Lassa fever was established in Sierra Leone to measure the frequency and case-fatality ratio of Lassa fever among febrile hospital admissions and to better delineate the clinical diagnosis and course of this disease. Lassa fever was responsible for 10%-16% of all adult medical admissions and for approximately 30% of adult deaths in the two hospitals studied. The case-fatality ratio for 441 hospitalized patients was 16.5%. We found the best predictor of Lassa fever to be the combination of fever, pharyngitis, retrosternal pain, and proteinuria (predictive value together, .81); of outcome, the best predictor was the combination of fever, sore throat, and vomiting (relative risk of death, 5.5). Complications included mucosal bleeding (17%), bilateral or unilateral eighth-nerve deafness (4%), and pleural (3%) or pericardial (2%) effusion. Lassa fever is endemic in this area and is a more-common cause of hospital admission and death than has previously been described; this disease must be considered when diagnosing febrile illness in West Africa.

A systematic study of Lassa fever in febrile children was undertaken over a four-year period, from August 1977 to August 1981, in the Eastern Province of Sierra Leone, West Africa. 479 patients were studied; of these, 245 had adequate specimens to confirm or exclude the laboratory diagnosis of Lassa fever. 51 cases of Lassa fever were identified (21% of patients from whom diagnosis was possible). Virus was isolated from 23 patients. All children had fever; cough and vomiting were present in over 60% of cases studied. The five to nine-year age group had the highest prevalence rate (41% of cases). Seasonal clustering occurred in April, May, and August. A significantly higher proportion of females than males had Lassa fever, a finding which remains to be explained. It is concluded that Lassa fever is a disease of significant concern in the paediatric age group.

Gastroesophageal reflux (GER) in the pediatric patient is a frequently recognized problem. Unlike the adult, in whom symptoms relating to esophagitis predominate, the infant and child may present with a variety of respiratory problems, vomiting and/or growth failure. GER is often seen in association with other conditions and must be considered in the evaluation of any pediatric patient with chronic recurring respiratory problems, vomiting or failure to thrive (FTT). Thirty-eight pediatric patients have been surgically managed at West Virginia University from 1977-1983 for GER. The patients fall into several different patterns of presentation and associated problems. Nine premature infants all with bronchopulmonary dysplasia (BPD) have undergone fundoplication for FTT, worsening BPD, and pneumonia. Seven infants and two older children had GER associated with previous esophageal atresia repairs. Esophagitis, vomiting and growth failure were the predominant complaints in this group, though all nine patients had recurring respiratory symptoms as well. Syndromes involving mental retardation and neurologic dysfunction affected another group of five patients, all of whom presented with the complications of long-term esophagitis. The remaining 15 children were otherwise healthy infants who had predominantly respiratory symptoms due to GER. The benefits of fundoplication in these severely affected infants and children far outweigh the relatively few complications. In the carefully selected patient, surgical management of GER is dramatically successful.

Necrotizing enterocolitis is an uncommon but dangerous disease in premature infants. Ten cases, seen over a three-year period at the Stanford University Medical Center, represented an incidence of 0.4 percent. The patients, six of whom died, derived from a general population, in contrast to the large series of patients reported in the literature in which the incidence was from 0.9 percent to 3.7 percent.(3-6)The initial symptoms-rapid respiration, periodic breathing, lethargy and irritability-were identical to those which occurred in numerous infants who had respiratory disease. Subsequent symptoms (abdominal distension, in 100 percent; vomiting, 80 percent; apneic spells, 70 percent; jaundice, 70 percent; guaic-positive stools, 60 percent) were those of nonspecific acute abdominal disease. The radiologist first made the diagnosis in 90 percent of cases. Interstitial air in the wall of the gut and the retroperitoneum, and portal vein gas were the most diagnostic radiographic features. Barium contrast studies were not helpful, and in one case led to the erroneous diagnosis of small bowel volvulus. Plain abdominal radiographs must be taken of all premature infants with symptoms of nonspecific acute abdominal disease. If the radiographs are negative, but symptoms continue, they should be repeated at frequent intervals, for early diagnosis is critical to institution of proper therapy.

Eight patients were seen within 15 minutes of intranasal self-administration of large amounts of pure D-lysergic acid diethylamide (LSD) tartrate powder. Emesis and collapse occurred along with signs of sympathetic overactivity, hyperthermia, coma and respiratory arrest. Mild generalized bleeding occurred in several patients and evidence of platelet dysfunction was present in all. Serum and gastric concentrations of LSD tartrate ranged from 2.1 to 26 nanograms per ml and 1,000 to 7,000 mug per 100 ml, respectively. With supportive care, all patients recovered. Massive LSD overdose in man is life-threatening and produces striking and distinctive manifestations.

Postcoital contraceptives, the so-called "morning after pill," are agents used as emergency treatment to prevent pregnancy after unprotected intercourse or contraceptive accidents. In the 1960s and early 1970s high doses of estrogens were used in 5-day courses such as diethylstilbestrol 25-50 mg a day or ethinyl estradiol 0.5-5 mg a day begun within 72 hours after coitus. Although effective, a considerable drawback of the associated nausea and vomiting as well as an increased risk of menstrual disturbance during the treatment cycle. Norgestrel alone in various dosages has been used postcoitally. Quingestanol has been used as a continuing postcoital agent in Latin America but proved unacceptable owing to nausea and irregular bleeding. In China "visiting pills" have been devised containing anordrin. In the West regimens of this sort have been superseded by the Yuzpe treatment of 100 mcg ethinylestradiol and 0.5 mg levonorgestrel initially, repeated after precisely 12 hours. The treatment must be initiated within 72 hours of exposure. Postcoital contraceptives act by combinations of mechanisms--the function of the corpus luteum is disrupted, tubal motility may be affected, and changes in endometrial biochemistry prevent ovoimplantation. In a multicenter trial involving 602 women Yuzpe reported a pregnancy rate of 1.6%. Other workers show comparable figures of 0-3%. The primary side effects of the current hormonal method are nausea, which occurs in 61% of cases, and vomiting, 20% of cases. Both are mild and of short duration. All postcoital methods carry a risk of ectopic pregnancy should the treatment fail. 3 ectopic pregnancies were recorded with diethylstilbestrol and 1 recently with the Yuzpe regimen. There have been no reports of thromboembolic complications. If a hormonal form of postcoital treatment fails, the theoretical possibility of the pregnancy being harmed cannot be ruled out. The patient needs to be counseled about this, and careful records should be kept. Also important is the taking of an accurate menstrual and coital history to exclude exposures earlier in the menstrual cycle. Lippes and coworkers showed the efficacy of copper IUDs as postcoital agents. These can be used up to 5 days from intercourse. An IUD is preferred if hormones are contraindictated, if exposure was more than 72 hours beforehand, if the woman desires the most effective method, and if she wants the IUD for longterm contraception. Postcoital contraception, however defined, raises ethical questions. Postcoital methods could be classed as contraceptive rather than abortive within the maximum period (defined by medical scientific consensus) that may elapse between intercourse and nidation.
