Pseudoseizures in the pediatric emergency department.

We report 10 cases of children with pseudoseizures who presented to a pediatric emergency department. Half of the patients were teenagers and seven were female. None of the patients had incontinence, and none was injured during the "seizure." All but one patient had invasive procedures or laboratory tests performed in the emergency department, and six of 10 patients were given anticonvulsants. Pseudoseizures are often confused with generalized tonic-clonic seizures.

Treatment of kerions.

Therapy for kerions was evaluated by randomly assigning 30 patients to one of four treatment groups: group A griseofulvin, group B griseofulvin plus erythromycin, group C griseofulvin plus prednisone, and group D griseofulvin, erythromycin, and prednisone. Data indicate that antibiotic and steroid therapy, in addition to griseofulvin, may reduce scaling and pruritus, but does not reduce the time it takes for kerions to flatten.

Microbiology of kerions.

Qualitative and semiquantitative bacterial culture specimens were obtained from 44 patients with kerions. Staphylococcus aureus was isolated from the scalp surface overlying the kerion in 29% of patients and from the pus within the kerion in 48% of patients. Gram-negative bacteria were found in the same locations in 11.3% and 18% of patients, respectively. The data indicate that bacteria are frequently cultured from kerions.

The pediatrician as expert witness. Participation and reaction to this activity.

Little is known about the qualifications and motives of pediatricians who provide expert witness testimony. Pediatricians in Pennsylvania were surveyed anonymously to learn more about this practice. Two hundred fifty-five (49%) of 520 pediatricians responded, and 126 of these physicians had provided expert testimony at some time. Fully affiliated medical school faculty members were more likely to act as expert witnesses than were other pediatricians. Seventy-seven (61%) did so to defend a fellow physician. Only eight (6%) were listed with an organization that provides expert witnesses. Pediatricians were selective about their involvement as expert witnesses, and 96 (76%) had refused to give testimony at some time. Most were paid an hourly rate, which was in keeping with charges for medical consultation or lecturing. More than 80% of respondents were unhappy with the present system of procuring expert witnesses.

Cephalexin and penicillin in the treatment of group A beta-hemolytic streptococcal throat infections.

OBJECTIVE: To determine whether cephalexin or penicillin is more effective in the treatment of group A beta-hemolytic streptococcal tonsillopharyngitis in children. DESIGN: Randomized, double-blind, crossover study conducted from 1981 to 1984. SETTING: Seven pediatric practices in the United States, including private offices and pediatric clinics. PARTICIPANTS: Of the 654 patients, 525 children and adolescents with clinical evidence of tonsillitis or pharyngitis and throat cultures positive for group A beta-hemolytic streptococcal infection were evaluable. Eighty percent of patients completed the study; none were withdrawn because of adverse reaction. SELECTION CRITERIA: Children and adolescents who had acute illness suggestive of group A beta-hemolytic streptococcal infection were enrolled in the study. Treatment was continued if the throat culture was positive for group A beta-hemolytic streptococcal infection. INTERVENTIONS: Four doses of cephalexin and penicillin (27 mg/kg per day) were prescribed to be taken on an empty stomach for 10 days. MEASUREMENTS/MAIN RESULTS: Symptomatic clinical failure occurred in 8% of penicillin-treated patients and in 3% of cephalexin-treated patients. Bacteriologic failure rates were 11% in the penicillin treatment group and 7% in the cephalexin treatment group. The combined treatment failure rate of clinical relapse plus asymptomatic bacteriologic failure was 19% in the penicillin treatment group and 10% in the cephalexin treatment group. Paired antistreptolysin-O titer increased significantly in 62.3% of penicillin-treated patients and in 64.2% of cephalexin-treated patients. Similarly, anti-DNase B titers rose 52.2% in penicillin-treated patients and 52.4% in cephalexin-treated patients. CONCLUSION: Cephalexin is a more effective drug than penicillin in the treatment of group A beta-hemolytic streptococcal throat infection in children.

Interfacing with police in the pediatric emergency department.

In summary, ED staff and local police departments should make a concerted effort to work together. The ED director should develop management protocols in conjunction with local police chiefs to plan strategies in advance. It is helpful to provide "orientation sessions," so that each group of professionals knows what to expect of the other. It may also be helpful to arrange tours of the ED so that police know where to go when they are called to the ED. All of these efforts should foster better care of children in the ED and will reduce tensions between the dedicated groups who work with such children.

Blood lead levels in children with foreign bodies.

To determine the risk of increased blood lead levels in children with aural, nasal, or gastrointestinal foreign bodies, the authors prospectively obtained venous blood lead and erythrocyte protoporphyrin levels from 40 study patients and two control groups without foreign bodies (65 patients presenting to a medical clinic and 40 patients presenting to an emergency department). A questionnaire was used to assess environmental and behavioral risk factors for lead poisoning in the three groups. Mean blood lead level was higher in children with foreign bodies (P less than .001), and they were more likely to have a venous blood lead value of more than 1.2 mumol/L (25 micrograms/dL, P less than .01) than patients in either control group. Seventy-eight percent of study patients had no prior lead screening by parent's report vs 64% of emergency department control subjects and 55% of medical clinic control subjects. Control patients in the emergency department had the same incidence of elevated blood lead values as patients enrolled from the medical clinic (6%). No differences in environmental risk factors were found among the three groups. Study patients more often had a history of pica or ingestion of a poison than control patients from the medical clinic. Inner-city children with foreign bodies have increased lead exposure and may have an increased risk for lead poisoning. In areas of high prevalence of lead poisoning, children with foreign bodies should be screened for lead poisoning in the emergency department. General lead screening in the emergency department may be justified for high-risk, inner-city populations.

Factors affecting outcome in meningococcal infections.

A prognostic score for evaluating meningococcal infections in patients consists of the following five features that indicate a poor prognosis: onset of petechiae within 12 hours of presentation; shock; normal or low peripheral leukocyte count; normal or low erythrocyte sedimentation rate; and absence of meningitis. Based on our experience and some published data, we suspected that the score may no longer be reliable. We reviewed the charts of 73 children with meningococcal infection from December 19, 1979 to December 19, 1987 and applied the prognostic score mentioned previously. Our findings indicate that although a low score is generally associated with a good outcome, a higher score is less predictive of poor outcome than previously suggested. A rash with petechiae or purpura, the presence of shock, and a normal or low peripheral leukocyte count continue to be predictors of poor outcome. Erythrocyte sedimentation rate was not evaluated owing to a limited amount of data. The absence of meningitis did not correlate with a worse outcome in our patients. Most patients who died had evidence of meningeal involvement at the time of presentation. Instead, altered mental status at presentation, particularly obtundation or coma, was an ominous sign. We conclude that absence of meningitis is not a good predictor of outcome, as was previously thought. Altered mental status at the time of presentation may prove to be a stronger indicator of poor outcome.

Three-wheeled vehicle injuries in children.

Injuries associated with nonmotorized three-wheeled vehicles were prospectively evaluated through a standard questionnaire during the summer months at the emergency department of the Children's Hospital of Philadelphia, Pa. Forty-four children, including 32 boys, with a mean age of 3.77 years, reported such injuries. Most fell (36.4%), but a second vehicle was often involved. Most children (33 of 44) were on low-slung Big Wheels. Head, neck, and dental injuries accounted for the majority. Most injuries were not serious. Two patients were admitted; both had fractures, one of them had a concussion. Data from the US Consumer Product Safety Commission corroborate the epidemiology of these injuries. Recommendations of safety precautions with non-motorized three-wheeled vehicles are reviewed.
