Treatment of infantile colic with dicyclominehydrochloride

We performed a prospective, randomized, double-blind, placebo-controlled clinical trial of dicyclomine hydrochloride using specific diagnostic criteria for infantile colic: spells of unexplained irritability, agitation, fussiness or crying lasting greater than or equal to 3 hours/day, occurring greater than or equal to 3 days/week, and continuing for greater than or equal to 3 weeks. Dicyclomine eliminated colic in 15 of 24 (63%) infants, whereas placebo was effective in six of 24 (25%) (corrected X2 = 5.42, P = 0.02). The study also addressed the hypothesis that parental distress caused by infantile colic affects subsequent temperament and sleep patterns. The data fail to document easier temperaments or longer sleep durations at 4 months in infants whose colic ceased during treatment.

Short-term holding room treatment of asthmatic children

We undertook a randomized trial to compare holding room treatment vs hospitalization of patients with childhood status asthmaticus. Two thirds of 51 patients were discharged from a holding room within 24 hours (mean 11.8 +/- 4.61 hours); the others required hospitalization. One third of 52 hospitalized patients received less than or equal to 1 day of intravenously administered therapy, and two thirds received less than 2 days of therapy (mean 45.6 +/- 12 hours). There were no statistically significant differences in recurrence rates between the two groups in the 28 days following status asthmaticus. For patients receiving less than or equal to 1 day of therapy, the holding room cost was

Acute psychosis after anesthesia : the case for antibiomania

PURPOSE To report childhood infection with Baylisascaris procyonis (raccoon round worm) manifesting as diffuse unilateral subacute neuroretinitis (DUSN) and choroidal infiltrates in association with neurologic disease (neural larva migrans). METHOD Observational case series, one with eye manifestations of DUSN, the other with choroidal infiltrates, both with severe neurologic degeneration. RESULTS Indirect immunofluorescence assays on serum and cerebrospinal fluid were positive for B. procyonis in one and serially positive and increasing in the other. Both children had a history of pica and raccoon exposure. CONCLUSIONS Baylisascaris procyonis infection is associated with two cases of severe neurologic degeneration with ocular lesions: DUSN and choroidal infiltrates. Although B. procyonis is known to cause DUSN, these cases indicate that concomitant ocular migration may accompany neural larva migrans. These are the third and forth cases in the US literature of neural larva migrans due to B. procyonis with eye findings.

A controlled trial of methylprednisolone in the early emergency department treatment of acute asthma in children.

Baylisascaris procyonis, the common raccoon roundworm, is a rare cause of devastating or fatal neural larva migrans in infants and young children. We describe the clinical features of two children from suburban Chicago who developed severe, nonfatal B. procyonis neural larva migrans. Despite treatment with albendazole and high dose corticosteroids, both patients are neurologically devastated. In many regions of North America, large populations of raccoons with high rates of endemic B. procyonis infection live in proximity to humans, which suggests that the risk of human infection is probably substantial. In the absence of effective treatment, prevention of infection remains the most important public health strategy.

Shigella dysentery with secondary Klebsiella sepsis.

The carriage rate of ampicillin-resistant Hemophilus influenzae type B in a chronic care facility was investigated. Up to 48% of the children carried this strain. Of interest was the finding of simulaneous carriage of ampicillin-resistant and ampicillin-sensitive HITB, a phenomenon which was detected by using both chocolate agar and chocolate agar containing 2 microgram/ml of ampicillin. A trial of sulfamethoxazole-trimethoprin successfully eradicated the ampicillin-sensitive HITB, but had no effect on the ampicillin-resistant HITB.

Bacterial endocarditis in 4 young infants. Is this complication on the increase

Seizure is a common problem evaluated in pediatric emergency departments. Serum chemistry analysis is often performed as a routine part of the diagnostic evaluation of children who arrive in the ED with seizure. From this retrospective study, we sought to determine 1) how often serum electrolytes (Na, K, Cl, CO2), total calcium, magnesium,ammonia, and glucose chemistries were performed, 2) the frequency of abnormalities detected, and 3) whether abnormalities resulted in a change in patient care. Three hundred eight ED charts from 12 consecutive months were reviewed. Data collected included age, sex, ED diagnosis, medical history, and physical examination. Charts were also reviewed for diagnostic tests ordered and patient management. Children were classified as having febrile (FS) or nonfebrile seizures (NFS) to establish diagnostic evaluation practices for each group as well as to determine rates of laboratory abnormalities. Three hundred eight children were enrolled, 108 (35%) FS and 200 (65%) NFS. The mean ages of FS and NFS patients were 2.1 and 5.7 years, respectively (P < 0.05, t-test). One hundred twenty-four of 308 (40%) children had at least one test performed; no abnormal test was thought to have caused seizure; none was treated. One hundred five of 308 (34%) were experiencing their first seizure. There was no difference in the likelihood of having a test ordered for children with a first seizure, regardless of seizure category. We concluded that 1) abnormal serum electrolytes, total calcium, magnesium, and glucose rarely cause seizure in children and 2) routine use of these tests in the ED is costly and does not contribute to seizure therapy.
