Whooping cough continues to be a major childhood disease in parts of West Germany. At age six, more than one third of the children in our area have had pertussis according to parental information, whereas only 12% received a specific vaccination. During a four-year period from 1984 to 1987, a total of 2,881 clinically diagnosed cases of whooping cough were investigated. The children had a mean age of 4.1 years, 11% of all patients were younger than one year and 6% of the patients were adults with a mean age of 35.8 years. No sex difference was observed in children (less than 20 years) with clinically overt whooping cough. The seasonal distribution showed that whooping cough was present throughout the year, peaking in early winter. In relation to clinical symptoms, the isolation rate of Bordetella pertussis or Bordetella parapertussis from nasopharyngeal swabs continuously decreased with the duration of paroxysms, starting with 56% positive swabs on day 1. Titers (greater than or equal to 1:100) of IgA-antibodies to B. pertussis antigens increased with the duration of paroxysmal coughing. B. pertussis, however, was also isolated from 152 of 964 patients without the clinical signs of whooping cough. IgA-antibodies were also found in 522 patients with non-typical respiratory symptoms, but not in healthy blood donors. Children with clinically diagnosed whooping cough were compared to a group of children showing the symptoms but without any clinical or laboratory signs of whooping cough. We can assume from our data that the incidence and duration of non-paroxysmal coughing, the nocturnal increase in coughing, fever, auscultatory findings and a contact anamnesis occurred with a similar frequency in the whooping cough group and the control group. Apart from the typical paroxysmal fits, whooping and vomiting were found significantly more often in the pertussis group. At least 19% of patients with a recent infection with B. pertussis, however, were not diagnosed by clinical symptoms. The leukocyte count differed only marginally between the three groups and was of no great diagnostic value. A relative lymphocytosis, however, was found significantly more often in whooping cough patients and in patients with laboratory-diagnosed infection with B. pertussis. Our study indicates that part of the symptomatology and some laboratory findings in whooping cough patients in endemic areas of West Germany may differ from the classical form of the disease. Furthermore, our data stress the importance of an accurate procedure in diagnosing B. pertussis infection, and this can be facilitated by a combination of bacteriological and serological tests.

Staff of the California Department of Health Services investigated the death of a parathion applicator in California that was thought to be pesticide-related. A crew of eleven workers (including six sprayers, three mixer/loaders, one mixer/sprayer and one foreman) had been applying 0.125% parathion spray to almond orchards for approximately three weeks. On the day of the fatality, a sprayer rapidly developed symptoms of salivation, sweating, and convulsions after a half-day of work. Despite aggressive medical treatment, the worker died within one hour of his initial symptoms. Significant laboratory results for the decreased case included: parathion residue on the inner and outer garments worn by the worker, parathion in the post-mortem gastric contents, and elevated urinary metabolites consistent with acute parathion intoxication. Interviews with the work crew revealed that three of the 10 workers had complaints of headaches, vomiting, and/or sore throat; yet, subsequent plasma and red cell cholinesterase tests of the co-workers did not show any significant depressions in comparison with pre-season baseline values. This worker death is consistent with prior reports of parathion-related sprayer/applicator intoxications and is the first worker-related parathion death in California since 1972. Substitution of pesticides with less toxic active ingredients or the elimination of parathion is recommended.

Sixteen patients acutely poisoned with aldrin were examined to evaluate a possible correlation between serum aldrin and dieldrin levels and clinical complaints. The patients were classified as having mild (N = 8), moderate (N = 5) or severe (N = 3) poisoning according to clinical symptoms. Concentrations of less than 20 micrograms/l were usually associated with mild poisoning, which involved complaints such as nausea, vomiting and epigastric pain, whereas concentrations of 100 to 200 micrograms/l were considered to represent moderate intoxication and were associated with nausea, vomiting, epigastric pain, headache, dizziness, and convulsions. Severe or fatal cases were associated with levels above 700 micrograms/l. Taken together, these results suggest that serum aldrin and dieldrin levels can be used as indicators of clinical prognosis after acute poisoning with these insecticides and that convulsions could suddenly occur even in the absence of prodromal signs or symptoms.

Acute experiments were performed on 20 guinea pigs. The animals were divided at random into four groups of five each: the non-acupuncture group for control and three electroacupuncture groups (EA-I, EA-II, EA-III). Four pairs of platinum-wire electrodes were implanted under serosa of the antrum and corpus, duodenum, jejunum. The gastroenteric electric activity (GEA) was recorded in conscious and fasting state. Needling was applied at position 1 cm below the knee, corresponding to Zusanli. The peripheral vomiting model was established by infusion of CuSO4 into the stomach. Observation was made with regard to latency of vomiting induced by infusion of CuSO4, duration of the symptom, number of fits in the first five minutes after the attack began, and the variation of amplitude and frequency of GEA. The results were as follows: (1) The GEA of normal guinea pigs showed regular cyclic changes. After latency of 3.7 seconds following the infusion, symptom of vomiting began appear. The GEA returned to normal after latency of 60 minutes. (2) During vomiting, the GEA was characterized by a series of spikes which were seen more obviously in the antrum and corpus; during serious fits of vomiting, duodenum and jejunum were involved. The GEA showed disordered and quicker rhythm with higher amplitude and frequency. (3) EA could not affect the latency of the peripheral vomiting, but it could shorten the duration of the symptom. Results of group EA-II (p less than 0.001) showed EA could reduce the number of fits during the first five minutes; results of group EA-I (p less than 0.01) showed that EA could lower the amplitude and frequency of the GEA (p less than 0.05) that rose during vomiting.(ABSTRACT TRUNCATED AT 250 WORDS)

Groups of 64 male and 64 female Wistar rats were given thiram at constant dietary doses of 0, 3, 30, and 300 ppm (0, 0.1, 1.2, and 11.6 mg/kg/day for males and 0, 0.1, 1.4, and 13.8 mg/kg/day for females) for 104 weeks. Eight males and eight females in each group were killed after Weeks 13, 26, and 52. For the dog study, four male and four female beagle dogs were alloted to each group and treated with the compound at 0, 0.4, 4, and 40 mg/kg/day for 104 weeks. The dogs in the 40 mg/kg/day group had severe toxic signs, including nausea or vomiting, salivation, and occasional clonic convulsion, and all were subjected to unscheduled necropsy before Day 203 of treatment. The dogs also had ophthalmological changes such as fundal hemorrhage, miosis, and desquamation of the retina which were consistent with the retinal lesions shown by histopathology. The rats of the high-dose group had retarded growth with a slightly decreased food intake. Anemia was evident in high-dose female rats and in middle- and high-dose dogs. Liver failure in male and female dogs and kidney damage in female dogs were detected in middle- and high-dose groups by blood biochemistry and/or histopathology. Regressive changes of the sciatic nerve accompanied by atrophy of the calf muscle were seen in female rats of the high-dose group but not in male rats. In high-dose rats, progression of myocardial lesions of the heart and chronic nephrosis of the kidney were depressed in males and females, respectively. Female rats of the middle- and high-dose groups had decreased occurrences of mammary fibroadenoma and decreased development of skin masses.

The incidence of cerebral haemorrhage was studied from a population-based stroke registry. The incidence was 12.3 per 100,000 per year in women and 13.9 per 100,000 per year in men, with a peak in the eighth decade and a male preponderance. Haemorrhages were deep seated and mostly due to hypertension. Recognised clinical characteristics of haemorrhage are acute onset, convulsion, vomiting, and disturbed consciousness. This study showed that cerebral haemorrhage may present with pure motor deficit or transient deficit preceding the stroke. The mortality was 51% in the first month, and 61% by two years.

Dehydration, in childhood as in adulthood, may origin from an inadequate water ingestion or an excessive water elimination. Causes may be found in fever, vomiting, scalds, pulmonary hyperventilation, diabetes. Water loss during acute diarrhea in children can be even 6-7 times higher in comparison with an healthy child. Together with water, electrolytes are lost. We differentiate dehydration in isonatremic d. (70% of cases), hyponatremic d. (10%) and hypernatremic d. (20%) basing on Sodium loss. Important dehydration causes severe clinical symptoms as shock, renal and cardiocirculatory failure, convulsion, coma. Symptoms at the central nervous system level derivate both from hyperosmolarity in brain cells and from thrombosis or hemorrhages in subdural sites. Dehydration, following acute diarrhea, is slight when weight loss is lower than 5%. The child health conditions still remain good. Dehydration become moderate if weight loss reaches 5% and the child starts suffering. When the weight loss reaches 10%, dehydration is now severe and circulatory deficiency becomes evident. When it is higher than 10%, prognosis is very severe and shock and coma may be observed. In the present work, we illustrate the different ways of rehydration after acute diarrhea. Initially, oral rehydration must be established with one of the oral solutions, differing each other for amount of electrolytes and glucose. Recently, a new solution, "supersolution", has been presented differing from the other ones for electrolytes concentration and for the presence of rice starch instead of glucose. In most cases of diarrhea, oral rehydration appears adequate but sometimes an intravenous rehydration becomes necessary, e.g. in case of vomiting, CNS depression and in any case of severe gastroenteric symptomatology.(ABSTRACT TRUNCATED AT 250 WORDS)

The use of Gadolinium-DTPA as a paramagnetic contrast agent in MRI with adults and juveniles concerning brain and spinal cord pathology is well proven since years. Tolerance and safety were excellent. In the FRG it is only introduced for children over two years of age. Therefore this report deals with the experience in four infants and small children under the age of two, who received gadolinium-DTPA for diagnostic purposes in pre- or post-operative circumstances. They all were suffering from neurological tumors and got additional diagnostic information in three cases. Clinical side-effects like urticaria, vomiting or convulsions had not been observed nor had pathologic changes of the biochemical parameters been noticed.

Gyromitra esculenta (Pers.: Fr.) Fr. and a few other mushrooms have caused severe poisonings and even deaths in humans. Clinical data are characterized primarily by vomiting and diarrhoea, followed by jaundice, convulsions and coma. Gastrointestinal disorders distinguish this poisoning. Frequent consumption can cause hepatitis and neurological diseases. The species of concern are mainly G. esculenta and G. gigas (Kromb.) Cooke (non Phill.). Nevertheless, recent advances in chromatography, biochemistry and toxicology have established that other Ascomycetes species also may prove toxic. Gyromitrin (acetaldehyde methylformylhydrazone, G) and its homologues are toxic compounds that convert in vivo into N-methyl-N-formylhydrazine (MFH), and then into N-methylhydrazine (MH). The toxicity of these chemicals, which are chiefly hepatotoxic and even carcinogenic, has been established through in vivo and in vitro experiments using animals, cell cultures and biochemical systems. When we consider the chemical nature and the reactivity of these natural compounds, we suggest that chemical and biochemical mechanisms may explain their intrinsic biological activity.

Symptoms and signs were recorded for 1007 infants younger than 6 months of age seen at home (298) or hospital (709) and correlated with four grades of illness severity. Most symptoms, present in the preceding 3 days, were associated with all grades of illness. Only four symptoms were not reported in well infants: a fluid intake less than a third of normal, convulsions, frank blood in the stools, and bile-stained vomiting. By comparison, many signs were seen only in ill infants. Those associated only with moderate or serous illness were marked retraction of the lower ribs, high-pitched or moaning cry, expiratory grunt, loss of alertness, central cyanosis, and severe hypotonia. Although these will not identify all seriously ill infants, parents and professionals should be taught to recognize these important symptoms and signs of serious illness.
