During 1984-1989, 19 Bedouin children, 4-8 years old, were hospitalized because of henbane plant (Hyoscyamus reticulatus) poisoning. There were 14 cases in the autumn, 3 in the spring and 2 in the summer. The most prominent signs were altered state of consciousness (including deep coma in 3) and flushed dry, warm skin in all. Pupils were dilated in 18 of the 19 and restlessness and hallucinations were present in 17. Less common were vomiting, increased tendon reflexes, convulsions, involuntary movements, ataxia, hypertension, hyperpyrexia and tachycardia. Therapy included intravenous physostigmine in 7 and sedatives (diazepam and triclofos) in 6. All were free of symptoms within 24 hours of admission. Henbane may grow as an annual or biennial. Renewed growth of leaf rosettes occurs before the first rains and they attract attention in the fields. The parts of the plant eaten by most of the children were the roots, which are easily mistaken for the edible roots of other plants. The main alkaloids in henbane are atropine (hyoscyamine) and scopolamine (hyoscine) which explains the clinical picture of mixed stimulation and depression of the brain. Educational measures should be undertaken to prevent poisoning of Bedouin children by eating such plants.

A case of polyarteritis nodosa (PN) in childhood involving various organs such as the gastrointestinal tract, skin, CNS, kidneys and liver with hypogammaglobulinemia is reported. This 6 month old girl was admitted to our hospital with vomiting, diarrhea, bloody stools with mucous and weight loss. For the past 5 months she had these abdominal symptoms. She was diagnosed as having PN of the Kussmaul-Maier variety on the grounds of the biopsy of skin lesion where a necrotizing vasculitis was found. Prednisolone and methylprednisolone pulse treatment were not effective in suppressing the progress of the disease. At the age of 1 year 7 month a combination therapy of prednisolone and immunosuppressants (cyclophosphamide) was started and this was found to be effective. She was discharged when she was 2 year and 2 month. The dosage of prednisolone was tapered as the activity of the PN decreased and she did well with a maintainance dosage of 9.5 mg/day. At 3 year 6 month of age she suddenly developed hypertension (the plasma renin activity was found to be 16.6 ng/m/hr. and the aldosterone 220 ng/dl). CNS involvement such as spinal cord dysfunction, left sided convulsions, cerebral hemorrhage developed 5 months later. Methylprednisolone pulse therapy was performed 3 times and 2 mg/kg/day of prednisolone was administered. In spite of this therapy she passed away with a massive cerebral hemorrhage at the age of 4 year 8 month. Unfortunately an autopsy was not performed. Results of the immunological tests proved that the hypogammaglobulinemia was a common variable immunodeficiency (CVI). It has been reported that primary immuno-deficiency syndrome is often associated with collagen disease and auto-immune disease. This lack of the defense mechanism against the virus or extra antigen could be related to the onset of collagen and auto-immune disease. As the correlation between CVI and PN has not been clarified this case is of interest as concerns the cause of PN.

Meningitis is endemic in Vanuatu and other Pacific island countries and has a high case fatality rate. The incidence in the southern island of Tanna is especially high. This descriptive study of 64 cases in children (under 15 years) on that island was undertaken over a 21-month period from January 1988 to September 1989. Meningococcus was identified in 23 cases (36%) and Pneumococcus in 12 (19%). The age distribution showed a high rate in under 1 year olds. The symptoms of fever, convulsion and vomiting were most common. Bulging fontanelle (in children under 1 year), neck rigidity, and altered level of consciousness were the most frequent signs. These signs were as frequent in meningococcal as pneumococcal infections and were used to develop a simple protocol for use in primary care. Delay in treatment or referral because of patients seeking traditional medicine is a major problem yet to be overcome. Only a weak association between admissions with meningitis and underweight or crowding was found in this study.

A guideline for early diagnosis of metabolic disorders affecting central nervous system during neonatal and early infancy was presented. Clinical manifestations associated with inborn errors of metabolism in the neonatal period are poor feeding, vomiting, diarrhea, abnormalities in muscle tonus, dyspnea, convulsion, coma and so on, and these are not specific to each disorder. However, such symptoms or signs as described below have often intimate relation to metabolic disorders: (1) previous children died of undetermined causes during early infancy; (2) complication of sepsis; (3) onset in the early neonatal period; (4) developmental and growth retardation. When newborns and infants have these symptoms or signs, we should start simple screening studies immediately for metabolic disorders, including CBC, hepatic function tests, blood glucose, lactate, pyruvate, ketone bodies, ammonia, blood gas analysis, urinalysis (including non-glucose reducing substance tests and FeCl3 reaction) and so on. As for CBC, we have to make our own effort to find spherocytosis and vacuoles in lymphocytes. Family history, especially the mother's personal history, is indispensable. During physical examinations, we must pay attention to facial appearance, skin color, macroglossia, hair abnormalities, peculiar odor of the urine and hepatosplenomegaly. When abnormality is found in these clinical signs or simple laboratory examinations, we should not hesitate to start dietary treatment even if special examinations for differential diagnosis are on the way.

Mothers' influence on their adolescent's tendency to seek medical care is examined in a national sample of 12- to 17-year-old children. A similar measurement model fits mother's and adolescent's tendency to seek medical care for the symptoms of a sore throat, stomachache, and vomiting. Maternal influence persists as the predominant effect on adolescents' tendency to seek medical care when sex, age, race, birth order, socioeconomic status, and intellectual ability are controlled. Older and more intellectually capable adolescents have a lower tendency to seek medical care. An adolescent's tendency to seek medical care is not influenced by gender and/or birth-order differences. Socioeconomic status variables indirectly influence adolescents' tendency to seek medical care through their primary influence on adolescent's intellectual ability.

One hour after suicidal ingestion of about 20 mL of a 38% solution of bromofosmethyl, CAS: 2104-96-3 (bromophos), a 52 year-old female was admitted to the hospital with extreme miosis, hypersalivation, hyperperistalsis and muscular fibrillation. Gastric lavage was performed and activated charcoal administered. Cholinergic symptoms were antagonized by repeated doses of 0.5 mg atropine. Because of the high dose of bromophos, hemoperfusion was performed with amberlite XAD4. The bromophos clearance during hemoperfusion was 95 mL/min (flow 200 mL/min). The patient received two doses of 500 mg obidoxime for recurrent muscular fibrillation. The further clinical course was uneventful. On day 4, the patient was transferred to a psychiatric ward because of persistent suicidality. In contrast to poisoning by most organophosphates, red blood cell acetyl cholinesterase was only minimally depressed but the plasma butyryl cholinesterase was initially decreased and normalized within a few days. The records of 25 patients reported to our Poison Control Center with ingestion of more than 1 g bromophos were also evaluated. The most frequent symptoms were miosis, hyperperistalsis, hypersalivation, agitation, nausea/vomiting and convulsions. Nine of the patients had no symptoms. Bromophos is relatively less toxic than its phosphate derivative, parathion.

A case of 25-year-old woman with mitochondrial encephalomyopathy, lactic acidosis and stroke-like episodes (MELAS) was reported. She had short stature, episodic vomiting with headache, several episodes with homonymous hemianopsia, progressive intellectual decline, generalized convulsion, muscular atrophy, sensory disturbance on the left side of the body, and primary amenorrhea. Lactate, pyruvate and the lactate to pyruvate ratio were elevated in the serum and cerebrospinal fluid. Muscle biopsy revealed ragged-red fibers. On electron microscopy there were subsarcolemmal aggregations of abnormal mitochondria with proliferation of crista and inclusions. Activities of the respiratory chain enzymes of the muscle mitochondria were normal. She showed a failure of GH response to arginine and levodopa and delayed response of serum GH to growth hormone releasing factor (GRF). She also showed decreased gonadotropin levels and delayed response of the hormone to LH-RH. In this case, a dysfunction of the hypothalamo-pituitary axis may be related to the short stature and primary amenorrhea. It is suggested that the hypothalamo-pituitary hypofunction may be one of the characteristic features in MELAS.

Patients with esophageal atresia (EA) or choanal atresia (CA) manifest similar clinical and pathophysiological features. To determine the significance of this observation, the clinical records of 80 patients with EA and 57 with CA were reviewed. This survey showed that similarities between the two conditions included inspiratory and expiratory dyspnea, episodes of reflex apnea and/or bradycardia, oropharyngeal dysphagia, vomiting, convulsions, hyperhydrosis, hyperthermia, sialorrhea, and sudden death. After the second year of life most symptoms disappeared spontaneously. In both conditions, respiratory effort resulted in partial or complete obstruction affecting both the inspiratory and expiratory phases of the respiratory cycle. Support for this finding was obtained by studying the breathing pattern of 3 patients with EA and 3 with CA, before and during postural respiratory loading. The data suggest that patients with EA are similar to those with CA, having upper airway instability that may result in obstructive hypopnea or apnea associated with expiratory grunting. It is possible that this upper airway instability is a manifestation of more general maturational dysautonomia previously not recognised in patients with EA.

During a 2-year period from January 1988 to December 1989, 125 patients (68 boys, 57 girls), aged 30 days to 9 years, were diagnosed as rotavirus gastroenteritis at this hospital. Diagnosis was made by identification of the rotavirus antigen in stool samples by latex agglutination assay. Ninety-nine (79.2%) of them were under 2 years of age. The seasonal peak in incidence was from January to March. The most common clinical characteristics were watery diarrhea (100%), followed by vomiting (68.8%), fever (68.0%), cough (42.4%), rhinorrhea (17.6%), convulsions (6.4%) and moderate to severe dehydration (1.6%). Fecal occult blood was positive in 4 patients and fecal leukocytes were positive in one patient. Stool cultures revealed concomitant infections with enteropathogenic Escherichia coli in 4 patients. Of the 106 patients who underwent serum electrolyte examinations, serum sodium concentrations ranged from 135-145 meq/L in 81.9% (86/106) and serum potassium concentrations ranged from 3.5-5.0 meq/L in 86.8% (92/106). Leukocyte counts greater than 15,000/mm3 were found in 10.8% (13/120) of the patients. All 125 patients recovered from the diarrheal illness on follow-up. Our results showed a different seasonal distribution of this disease from that of a previous observation between 1983-1984 in Taipei City and provides original clinical information on rotavirus gastroenteritis in children living in an area of Taipei County. Using the simple and rapid latex agglutination assay, we can make early diagnosis of rotavirus gastroenteritis. Thus, early treatment and early isolation of patients to prevent nosocomial infection among hospitalized patients is possible.

Recently introduced chloroquine resistant malaria has altered the clinical picture and complicated the overall management of malaria. 113 adults with proved malaria admitted at Harare Central Hospital, Zimbabwe, were evaluated to determine the incidence, nature, relationship to morbidity and mortality and response to treatment of the complications due to malaria. 47.7 pc (52 of 109) patients had relatively chloroquine resistant malaria. 87.4 pc (99 of 113) had complications whose percentage frequency of occurrence were: Anaemia 51.2 pc, diarrhoea and/or vomiting 42.2 pc, cerebral malaria +/- fits 39.2 pc, renal insufficiency +/- hyperkalaemia 26.4 pc, hypoglycaemia 15.6 pc, jaundice 15.2 pc, neuro-psychiatric 15.0 pc, shock 10.6 pc, concurrent sepsis 8.9 pc, pulmonary oedema 3.5 pc and hyperpyrexia 1.7 pc. Multiple complications in the same patient were common. The combination of cerebral malaria and renal insufficiency had the worst mortality (p less than 0.001). All patients dialysed, however, survived. Non-iron deficiency anaemia, 91.7 pc (51 of 55) and diarrhoea and/or vomiting, were common, worsened morbidity but not mortality (p = 0.555). A seriously-ill patient with malaria should be suspected of having complications and chloroquine resistance and should be referred promptly to a centre with facilities for dialysis. Anti-malaria drugs should be mixed in a dextrose solution and iron supplements should not be given routinely.
