A 22-year-old male presented with a brief history of progressive encephalopathy. One week previously, he had developed an upper respiratory infection that resolved spontaneously and was followed by intractable vomiting. He had taken salicylates for several days during the viral syndrome. The diagnosis of Reye's syndrome was confirmed by hepatic histology. Aggressive conservative management was followed by complete metabolic and neurological recovery. There are fewer than 10 reported cases of Reye's syndrome in adults but this disease may be more common than is generally suspected. The diagnosis should be considered in patients presenting with emesis and obtundation, who have recently had a viral illness and exhibit elevated blood ammonia and transaminases with normal cerebrospinal fluid. Confirmation is achieved by liver biopsy. Therapy is directed toward aggressive reduction of increased intracranial pressure.

During the 1980 influenza B outbreak in King County, Washington, 11 children whose asthma had previously been controlled with a stable theophylline dose, developed theophylline toxicity on this same dose. Two had seizures, eight had nausea and vomiting, and three had headaches. All had clinical evidence of a febrile viral illness. The toxicity appeared to be related to decreased theophylline clearance, which gradually returned to preillness levels over a period of one to three months. Six of ten children had serologic evidence of influenza B, which is presumed to be the cause of the altered clearance. In children receiving chronic theophylline therapy, symptoms of vomiting, headaches, or seizures during a viral illness may be due to theophylline toxicity rather than the virus. Such patients should have an immediate serum theophylline determination, even if previous levels have been in the therapeutic range.

A serological study of canine parvovirus (CPV) infections in a colony of dogs was conducted over a period of 8 months. Twenty-two of 24 adults samples initially had significant antibody titres to CPV. Nine litters of puppies were bled at fortnightly intervals and the sera tested for antibodies to CPV. Twenty-nine of 35 naturally PV infections observed were subclinical. A puppy in one litter developed vomiting and diarrhoea during the same period as seroconversion to CPV. Four puppies from a further litter developed histologically confirmed myocarditis. Serological testing of this latter litter indicated that the virus infections occurred between 2 weeks prior to and 1 week post whelping, and that clinical disease developed 20-40 days after viral infection. The mean half life of the decline of passively derived immunity to CPV was 8.3 days.

All references about a new viral infection, which was seen in Sudan and Zaire at 1976 called "Ebola Haemorrhagic Fever" with high fever, diarrhoea, vomiting and great systemic haemorrhagic manifestations were reviewed. We discussed the history, etiology, epidemiology, source of infections, mode of transmission, period of communicability, clinical and laboratory findings and control measures of the disease. Some comments were made about what could be done, if a new disease of unknown etiology is seen in any part of our country.

Enteric intussusception is one f the most frequent causes of acute abdomen in early childhood, with an incidence of 1.3-2/1000 children born and higher frequency from the third to the twelfth month. Primary intussusception is related to predisponsing factors such as peristalsis disorders or Peyer's patch hypertrophy induced by viral infection. Secondary intussusception is due to organic injury in the intestinal wall. The most involved sites are the terminal ileum and the ileocecum, the most frequent type is ileocolic intussusception. Many clinical forms exist, including acute enteric intussusception with its pathognomonic triad intermittent abdominal pain, emesis and rectal bleeding and the atypical form with a neurological presentation, where sopor, myosis and muscular atonicity are dominating, Intussusception can also present in a subacute or chronic form with a slow and apsecific onset. In a retrospective investigation we examined 30 cases of intussusception in children hospitalized at the Pediatric Clinic of Pisa from the 1960s up to today. Our patients (16 males and 14 females) were aged between one month and two years. Clinical presentations resulted in; typical forms (60%), atypical forms (16%), subacute forms 13%) and recurrent forms (10%). Clinical suspicion was confirmed either by the presence of blood observed during rectal exploration, which is a pathognomonic sign, or by the opaque enema which led to recovery by means of hydrostatic reduction in 40% of the cases. The remaining patients (60%) underwent surgery.(ABSTRACT TRUNCATED AT 250 WORDS)

Dengue fever is a viral disease, transmitted to man via mosquito bites. It is endemic in tropical regions (10 million infected annually) and is characterized by high fever, headache, myalgia, lethargy, vomiting, rash and neutropenia. The upward trend in the number of young Israelis visiting tropical countries increases the number of those potentially exposed to this disease. We present 4 Israelis who returned with dengue fever from Thailand.

Seventy-seven episodes of pneumococcal meningitis in 69 patients were reviewed. Twelve (15.6%) episodes occurred in those over 60 years old, 14 (18.2%) in patients between 10 and 60 years, 22 (28.6%) in patients between 2 and 10 years and 29 (37.7%) in those under 2 years. Overall mortality was 13.0% (10/77) and age of > 60 years was significantly associated with mortality (P < 0.05). Twelve episodes resulted in disabilities, eight of which were in those under 2 years, and took the form of hearing impairment in nine. Many patients had predisposing conditions with aural pathology, malignancy and diabetes mellitus being commonest in those over 10 years of age and aural pathology, preceding viral infection, renal disease, sinusitis or recent lower respiratory tract infection commonest in those aged between 2 and 10 years. Three of five patients with recurrent meningitis had CSF leaks. The most common features at presentation were fits, irritability, diarrhoea, and bulging fontanelles in those under 6 months; vomiting, drowsiness and poor feeding in those between 6 months and 2 years; neck stiffness, vomiting and drowsiness in those between 2 and 10 years while neck stiffness, focal neurology, headache and vomiting were commonest in those over 10 years old. Fever was common in all age groups as were foci of infection outside the CSF, with chest infections being significantly associated with mortality (P < 0.05). Of the laboratory parameters measured, low platelets (< 100 x 10(9)/l and high blood urea (> 7 mmol/l) were associated with mortality (P < 0.05). Blood cultures grew Streptococcus pneumoniae in 79.7% patients. Seventy-four (96%) patients had CSF taken of which 81% had gram films which were positive and interpreted correctly as showing pneumococci. Pneumococci were grown in 87.8% CSF cultures and all were sensitive to penicillin but a single isolate was chloramphenicol resistant. Many different antimicrobial drugs were used but penicillin plus chloramphenicol was the most commonly employed after the results of CSF microscopy were known and penicillin alone after culture results were available. Penicillin mono-therapy was associated with a low mortality.

Reye's syndrome is considered a disease of the pediatric age. It is characterized by a prodrome of viral illness followed by vomiting and encephalopathy with associated hepatic dysfunction. This syndrome is potentially life-threatening with high morbidity and mortality rates. There are 27 other cases of adult onset Reye's syndrome reported in the literature. We describe a 18-year-old woman who developed varicella and four days later started with vomiting, delirium and in the following day she became comatose. Laboratory tests of liver function and pathology of a liver biopsy proved the diagnosis. The patient survived. A review of the proposed pathogenic mechanisms are presented. Our patient represents case the number 28 in world literature and the first in the mexican literature.

The aim of this work was to offer a description of the clinical manifestations developed by patients under 1 year who had dengue virus infection and dengue hemorrhagic fever during the epidemic which broke out in 1981, and to determine if the passive transfer of maternal dengue antibodies to the fetuses influenced the occurrence of a severe development of the disease, through a retrospective study. In 20 cases, type 2 dengue virus infection was confirmed. Eight patients showed the clinical manifestations of dengue hemorrhagic fever of dengue shock syndrome (DHF/DSS), and the other 12 had the typical dengue virus infection. The former were of the white racial phenotype, aged under 6 months. There was a predominance of type 1 dengue antibodies in the mothers of children with DHF/DSS. Fever, rash, vomiting and diarrheas (not frequent) appeared in the two clinical manifestations of the infection; blood leukocytes were predominantly lymphocytic; and erythrocyte sedimentation was always normal. Patients with DHF/DSS presented with some bleeding (87.5%); cyanosis and ascites (37.5%); and shock (25%), as well as hepatomegaly. All these infants with DHF/DSS had thrombocytopenia and most of them showed hemoconcentration. No deaths occurred.

Norwalk virus infection is a common cause of gastroenteritis in humans. The clinical features and virologic and immunologic responses following oral administration of Norwalk virus to 50 volunteers were monitored. New ELISAs using recombinant virus particles as the antigen source were used to assess the pattern of virus shedding and the specific immune responses. Forty-one subjects (82%) became infected; 68% were symptomatic and 32% were asymptomatic. The proportion of subjects infected was similar for those with and without preexisting antibody (82% vs. 60%; P > .2). The magnitude of seroconversion was highest in subjects who had vomiting. The peak of viral shedding was between 25 and 72 h, and virus first appeared in stool at 15 h. Specimens collected 7 days after inoculation remained positive. These results show a higher infection rate, more subclinical infections, and longer virus excretion following Norwalk virus inoculation than previously recognized.
