In the period 1970 through 1979, the Coxsackie B1, B2, B3, B4, and B5 viruses constituted 24 percent of more than 18,000 enteroviruses isolated and reported through national surveillance. Young children, especially males, were most frequently affected: 48 percent of the national surveillance population were less than 5 years of age, including 30 percent who were less than 1 year old. Among the most frequently reported clinical syndromes associated with B infection were meningitis (in 56 percent of patients with B1-B5 infections), encephalitis (in 15 percent), and respiratory tract disease (in 14 percent). Carditis, a well-known B syndrome, was reported with only 2 percent of B1-B5 infections. Like most enteroviral agents, Group B viruses were isolated primarily during the summer: 87 percent of all these isolations were made during the 5 months from June through October. Although B2, B3, and B4 viruses were isolated at relatively uniform levels each year, B1 and B5 viral illnesses occurred nationwide as explosive epidemics only in certain years. A separate population of B-infected patients, identified by the Nassau County Medical Center (NCMC) Virus Laboratory, East Meadow, N.Y., during the same 10-year period, was studied to compare epidemiologic characteristics and to evaluate in greater detail clinical and laboratory features of B infections. Because of more active solicitation of specimens for testing, ascertainment in the NCMC system was more complete. The most frequently reported clinical findings at NCMC included fever (97 percent of cases), which was biphasic in 27 percent; pharyngitis (85 percent); vomiting (56 percent); headache (49 percent); other respiratory signs and symptoms (44 percent); diarrhea (40 percent); abdominal pain (33 percent); rash (31 percent); and otitis (28 percent). Rash was more frequently associated with younger than with older age groups (P < .01) for all B agents. Overall, throat (T) and rectal (R) swabs had the highest B-positivity rates among known infected patients(83 percent for T and 78 percent for R). Only for T was the positivity rate correlated with the interval between onset of illness and obtaining the specimen (P < .05). B agents grew most quickly from T specimens, but most reliably from R specimens. On the basis of these data,the authors recommend that both T and R specimens be obtained from every patient for whom prompt and reliable laboratory diagnosis of B infection is sought.To the authors' knowledge, these results from 10 years of national surveillance represent the largest surveillance summary of Coxsackie B viruses to date in the literature. Comparison of these results with those reported over the same 10 years by NCMC reflects differences that arise mostly because of differences in ascertainment systems.

A two year combined retrospective and prospective study of 555 acute medical admissions to a district general hospital was carried out to assess the value of emergency biochemical, haematological, radiological, and electrocardiographic tests in diagnosis and treatment. For the study the tests were considered helpful only if they disclosed an abnormality and resulted in a definite diagnosis or change of treatment which would not have been possible from the history and examination alone. A total of 2372 emergency tests were carried out in the 555 patients who presented with 579 acute medical problems. Only 403 (17%) of the test results were abnormal and, of these, only one third helped in treatment and less than one third helped in diagnosis. The most useful diagnostic tests were serum amylase activity in abdominal pain, the electrocardiogram in chest pain, the chest radiograph in respiratory problems, and cerebrospinal fluid analysis in suspected meningitis or subarachnoid haemorrhage. The most useful tests in treatment were blood sugar value in diabetes, PCO2 in obstructive airways disease, and haemoglobin concentration in gastrointestinal haemorrhage. Of the tests requested by far the most often--blood urea and serum electrolyte concentrations--only 7% gave abnormal results and were rarely of any help in either diagnosis or treatment. Analysis of the reasons for the uncritical use of emergency tests by house officers suggested that better undergraduate training, regular audit by senior members of medical units, abolition of routine investigational procedures, and more selective laboratory reports would help to build up the house officer's confidence in his own skills of history taking and physical examination without recourse to indiscriminate use of laboratory and other investigations.

Campylobacter jejuni (previously called "related vibrio") has recently become recognized as an important cause of acute diarrhoeal disease in many countries. As with other intestinal pathogens, the clinical picture of C. jejuni infection varies from symptomless excretion to severe disease. The incubation period averages two to five days. Fever, abdominal pain and bloody diarrhoea are the usual symptoms of campylobacter enteritis. Although it is normally a self-limiting disease, complications such as cholecystitis, peritonitis, septicaemia and meningitis occasionally arise. The small intestine is thought to be the main site of infection, but the colon is also regularly involved. The disease might be more accurately described as an enterocolitis. Campylobacters, like salmonellae and yersiniae, are thought to be pathogenic by virtue of their invasive ability. Chemotherapy is usually effective. Erythromycin is commonly used for patients ill enough to require specific treatment. Although the infection can be transmitted from person to person, it is mainly a zoonosis with many possible routes of infection. Poultry is a potential source of infection, dogs may also transmit the disease and there have been major outbreaks of campylobacter enteritis from the consumption of untreated or inadequately treated milk and water. Further epidemiological work is hampered by the lack of suitable typing techniques.

Cases of human infestation by Fasciola hepatica are not uncommon in Spain and other European countries. We report our experience with 20 patients diagnosed from 1982 to 1991 and present a critical review of published cases from western countries. Because F. hepatica has a special tropism for the liver, abdominal pain, hepatomegaly, and constitutional symptoms are among the most common manifestations of acute-stage fascioliasis. However, in the chronic stage, biliary colic and cholangitis are the predominant manifestations. The clinical spectrum of fascioliasis is variable, and patients may present with extrahepatic abnormalities, such as pulmonary infiltrates, pleuropericarditis, meningitis, or lymphadenopathy. Therefore, a high index of suspicion is required to establish a correct diagnosis. Eosinophilia is the most frequent laboratory abnormality. The CT scan has become a useful technique in the diagnostic work-up. A definitive diagnosis may be established by the observation of parasite ova in the feces, but most cases may be diagnosed by serologic methods. Triclabendazole and bithionol are the most effective drugs against F. hepatica. The efficacy of praziquantel is controversial.

43 children suffering from borreliosis, meningitis and septicemia were treated with ceftriaxone. A six year old boy with acute jaundice due to ceftriaxone induced cholelithiasis encouraged us to reevaluate the frequency of ceftriaxone induced cholelithiasis and its' sequelae in children in a prospective study. Out of 43 children (age 6.3 years, 4 months to 16 years, male: female 25:18), 20 children (46.5%) showed sonographical evidence for ceftriaxone induced cholelithiasis after a treatment of at least 10 days. Two of them even had signs of intrahepatic cholestasis, 3 kids suffered from severe abdominal pain, non of them showed serologic abnormalities. Another 5 children (11.6%) had sludge in the gallbladder without evidence for cholelithiasis. In all patients the "pseudocholelithiasis" spontaneously resolved within at most 2 months. We suggest a sonographical examination of the gallbladder at the end of the ceftriaxone treatment in order to detect cholelithiasis, which might call for further monitoring and maybe dietary treatment.

Only 15 cases of any etiology of Neisseria meningitidis peritonitis have been reported in the world literature since the first case in 1917. We report the first case in a continuous ambulatory peritoneal dialysis (CAPD) patient presenting with abdominal pain and cloudy peritoneal dialysis fluid. A lumbar puncture was normal. The patient died despite therapy with ceftriaxone. Autopsy confirmed this was a case of primary N. meningitidis peritonitis. Of the 15 cases of N. meningitidis reported as a cause of peritonitis, 9 patients were less than age 35 with no underlying diseases. Five cases were associated with cirrhosis or alcohol abuse. Two cases were associated with meningitis, and 1 patient was on steroid therapy for systemic lupus erythematosus. Nine of 15 patients recovered. In conclusion, N. meningitidis should be considered as another rare cause of peritonitis in patients on CAPD.

During the winter of late October, 1990 to March, 1991, echovirus type 30 meningitis affected 10 children aged 3-9 years of age in Mikuni, Japan. Five patients presented with constipation, four had diarrhoea, while five complained of severe abdominal pain, in addition to typical symptoms and signs compatible with aseptic meningitis. Echovirus type 30 was isolated from the CSF of nine, from the faeces of 10, and from the throats of eight children. All showed a significant antibody response to echovirus type 30 in paired samples of serum. Antigenic variation and thermostability of a representative isolate indicated some changes in virus structural proteins, possibly reflecting an altered tropism for tissues in the gastrointestinal tract.

This study reviewed 549 malpractice claims filed against emergency physicians in Massachusetts from 1975 through 1993, with a total of $39,168,891 of indemnity and expense spent on the 549 closed claims. High-risk diagnostic categories (chest pain, abdominal pain, wounds, fractures, pediatric fever/meningitis, epiglottitis, central nervous system bleeding, and abdominal aortic aneurysm) accounted for 63.75% of all closed claims and 64.23% of the total indemnity and expense spent on closed claims. Missed myocardial infarction (chest pain) claims accounted for 25.47% of the total cost of closed claims but only 10.38% of closed claims. The number of claims for missed myocardial infarction increased in the post-1988 closed claim group compared to the pre-1988 group; fractures and wounds were significantly less frequent in the post-1988 group. The frequency of high-risk claims decreased in the post-1988 group, largely because of the decline in fracture and wound claims. The category of missed myocardial infarction had a larger percentage of claims closed with indemnity payment than without indemnity payment. This parameter may serve as a marker for the overall seriousness of claims associated with a particular allegation, unlike the average cost per claim, which may be skewed by a few large awards.

Streptococcus pneumoniae is a frequent bacterial cause of pneumonia, bacteremia, meningitis, and otitis media in infants and children. Primary pneumococcal peritonitis, however, is rare in children and is usually associated with an underlying medical condition (such as nephrotic syndrome) or with upper genital tract disease in females, Pneumococcal upper genital tract infections in the premenarchal child are extremely unusual. Epidemiologic reviews of pneumococcal serotypes causing infection in children have indicated that serotype 1 is an uncommon pathogen of pelvic disease in children. We describe three children who presented with abdominal pain and a toxic appearance; appendicitis was initially suspected in all three children, but peritonitis due to S pneumoniae serotype 1 was subsequently diagnosed in all three. Each child had a tuboovarian abscess that was demonstrated radiographically. Two children had complicated courses, but all ultimately recovered. The epidemiology and possible tropism of serotype 1 isolates for the female upper genital tract are discussed.

Thirty-nine Danish cases of Capnocytophaga canimorsus septicemia were reviewed to determine the clinical course of this infection. The cases of septicemia were related to recent dog bites or other close contact with dogs. The period from the bite to the onset of symptoms ranged from 1 to 8 days. The mean age of the patients was 59.1 years (range, 28-83 years). Underlying conditions included previous splenectomy and alcoholism. Thirteen patients had previously been in good health. Common initial symptoms were fever, malaise, myalgia, vomiting, diarrhea, abdominal pain, dyspnea, confusion, headache and skin manifestations. Disseminated intravascular coagulation developed in 14 patients, meningitis in 5, and endocarditis in 1. Twelve of the patients died. All patients except two were treated with penicillin or ampicillin. Five patients had received antibiotics prior to admission. Attention should be drawn to C. canimorsus septicemia in cases of febrile illness following dog bites or contact with dogs, as well as those involving previously healthy persons. The incidence of this condition in Denmark is estimated to be 0.5 case per 1 million people per year.
