Management of febrile children with urinary tract infections.

This study of the management of children with fever and urinary tract infection (UTI) was conducted to identify factors associated with initial admission, outpatient treatment, and outpatient treatment failure. A retrospective chart review identified children 3 months to 16 years of age with an emergency department (ED) diagnosis of cystitis, pyelonephritis, or UTI, a positive urine culture, and an ED temperature of >38 degrees C. Sixty-nine patients (90% female) were studied; 19% were admitted initially. Age younger than 2 years was associated with admission (P < .001). Of those initially discharged, 63% received parenteral antibiotics (usually intramuscular ceftriaxone), followed by oral antibiotics; 9% failed outpatient treatment. Outpatient failure was associated with higher initial temperatures (median 40.1 degrees C v 39.2 degrees C, P=.03, Mann-Whitney U) but was unrelated to age, initial white blood cell count, or use of parenteral antibiotics. These results indicate that most children with fever and UTI do not require hospital admission; those with temperatures of > or = 40 degrees C are at increased risk for outpatient failure.

Pediatric male rectal and genital trauma: accidental and nonaccidental injuries.

OBJECTIVE: To characterize accidental pediatric rectal/genital trauma in males and compare these physical findings to a cohort of boys evaluated for sexual abuse. DESIGN: Retrospective chart review. SETTING: Tertiary pediatric trauma center/sexual abuse clinic. PARTICIPANTS: Male patients evaluated in the emergency department for rectal/genital trauma from 9/1/89 through 10/31/93 ("accidental group"). Male patients referred to Child Protection Services for suspected sexual abuse from 1/1/93 through 12/31/95 who had abnormal genital physical findings ("sexual abuse group"). MAIN OUTCOME MEASURES: Outcomes measured included age, mechanism of injury, category of diagnosis, location of injury, and type of injury. RESULTS: Forty-four male patients comprised the accidental group, aged six months to 17 years. The most common mechanism was a fall onto an object (34%). The most common injuries were lacerations/perforations of the scrotum (36%) followed by penile lacerations/perforations (25%). No patient had an isolated rectal laceration. Forty-four male patients with positive physical findings comprised the sexual abuse group. Ages ranged from seven months to 18 years. All patients had rectal lesions. Penile lacerations/perforations were the only other injuries documented, occurring in two patients. CONCLUSIONS: Accidental rectal/genital trauma in the pediatric population is uncommon; scrotal trauma occurs much more frequently than rectal trauma. Rectal/genital injury in the sexual abuse group typically involves only the rectal area. Sexual assault should be considered in patients with isolated rectal injury or whenever the alleged history does not correlate with physical findings.

Using the hand to estimate the surface area of a burn in children.

OBJECTIVE: Estimation of the surface area involved is vital to evaluation and treatment of burns. Common teaching suggests the palm approximates 1% of the total body surface area (TBSA). However, early century literature suggests the palmar surface of the entire hand approximates 1% of the TBSA. We sought to determine whether the palm or the entire palmar surface of the hand approximates 1% TBSA in children. DESIGN: A prospective, convenience sample. MATERIALS AND METHODS: Using height, weight, and standard nomograms, body surface area was determined. A photocopy of the hand was used to determine the surface area of the palm and the entire palmar surface of the hand. RESULTS: In 91 children, the mean percent of the TBSA represented by the entire palmar surface was 0.94% (95% confidence interval (C.I.) 0.93-0.97), and the mean percent of the TBSA represented by the palm was 0.52% (95% C.I. 0.51-0.53). CONCLUSION: The entire palmar surface of a child's hand more closely approximates 1% TBSA, while the palm approximate 0.5% TBSA.

Treatment of convulsive status epilepticus with propofol: case report.

INTRODUCTION: Convulsive status epilepticus (CSE) refractory to treatment with benzodiazepines, phenobarbital, and phenytoin presents a challenge to pediatric emergency and critical care specialists. Prompt seizure control may prevent mortality and morbidity. CASE: A nine-month-old girl with hereditary fructose intolerance had prolonged, refractory CSE. Her seizures promptly stopped after administration of propofol (3 mg/kg bolus followed by infusion of 100 micrograms/kg/min). This dose resulted in electroencephalographic burst suppression. She required endotracheal intubation, invasive hemodynamic monitoring, and pressor support. DISCUSSION: This is the first pediatric case of prolonged, refractory CSE treated with propofol. The adult experience is reviewed. Propofol should be used only in a setting where definitive airway control and hemodynamic support is possible.

Cyclizine abuse by teenagers in Utah.

Substance abuse by teenagers is common, often involving use of alcohol and illicit drugs. Ingestion of cyclizine hydrochloride, a nonprescription medication, was noted to occur frequently in Utah for abuse reasons. A retrospective review was conducted of patients younger than 18 years of age over a 3-year period who intentionally ingested cyclizine identified from Utah Poison Control Center records. Eighty patients were included; 42 patients underwent hospital record review. Abuse accounted for 89% of cyclizine ingestions; hallucinations (70%) and confusion/disorientation (40%) were the most notable symptoms. Tachycardia (52%) and systolic hypertension (69%) were frequently present in patients who presented to a hospital. No serious complications occurred. This study illustrates teenage abuse of one nonprescription antihistamine presumably to induce hallucinations. Abuse of over-the-counter medications by adolescents may be more appealing than illicit drug use for numerous reasons, and may be more common than appreciated.

The utility of head computed tomographic scanning in pediatric patients with normal neurologic examination in the emergency department.

Head injury is a frequent cause of morbidity and mortality in pediatric trauma. Guidelines for obtaining computed tomographic (CT) scans in the child with mild head injury are poorly defined. This study investigated the utility of head CT scanning in the pediatric patient presenting with normal neurologic examination. All patients undergoing head CT scanning for trauma in the emergency department (ED) at a tertiary care pediatric trauma center during 1992 were identified (508). Charts were reviewed for historical and physical examination findings, CT results, and need for neurosurgical intervention. Patients were excluded if they had an abnormal neurologic examination (179), known depressed skull fracture (11), bleeding diathesis (3), age older than 18 years (1), or developmental delay (1). Included were 313 patients (median 5.5 years) who presented with clinical variables including sleepiness (38%), vomiting (34%), headache (30%), loss of consciousness (LOC) (25%), irritability (22%), amnesia (20%), and seizures (8%). An abnormal head CT was noted in 88 cases (28%); 79 (25%) were traumatic abnormalities involving the skull and/or contents. Thirteen patients (4%) had intracranial injuries (ICI); all had either a linear (10), basilar (2), or depressed (1) skull fracture noted on CT. Four patients required neurosurgery, three for epidural hematoma, and one for a complicated orbital fracture (without ICI). No clinical variables (seizure, LOC, vomiting, headache, confusion, irritability, sleepiness, amnesia) were associated with ICI (P > 0.05). In pediatric head trauma patients, with normal neurologic examinations in the ED, ICI occurs < 5% of the time and neurosurgery is needed in 1% of the cases. Commonly used clinical variables are not associated with ICI in these children.

Laboratory presentation in diabetic ketoacidosis and duration of therapy.

OBJECTIVE: To determine if initial emergency department (ED) laboratory parameters in children with diabetic ketoacidosis (DKA) can predict the minimum duration of continuous insulin therapy and aid in ED triage. DESIGN: Retrospective chart review, over a four-year period. SETTING: Tertiary care pediatric center ED. PATIENTS: All patients in DKA, managed with a standard hospital protocol were included. Standard therapy consisted of an intravenous infusion over an hour of normal saline or Ringer's lactate, followed by 0.45% saline (potassium acetate/ phosphate added) at 1.5 times maintenance and insulin infusion (0.1 units/kg/h). New-onset diabetic patients were excluded. MAIN RESULTS: One hundred thirty-two visits (45 patients, 55.5% female) were reviewed. Three of 60 (5%) patient-visits with moderate to severe DKA (serum pH < 7.20 and serum bicarbonate concentration < 10 mmol/L) had their acidosis corrected (serum pH > or = 7.30 or serum bicarbonate concentration > or = 15 mmol/L) within four hours compared to 33 of 72 (46%) patient-visits with mild DKA (serum pH > or = 7.20 or serum bicarbonate concentration > or = 10 mmol/L) (P < 0.0001). The acidosis was corrected within six hours in 69 and 11% of the mild and moderate-severe DKA group, respectively (P < 0.0001). CONCLUSIONS: Initial laboratory presentation can help predict the minimum necessary duration of therapy in pediatric patient with DKA, aid early triage decision in the ED, and select a subgroup of patients who may be considered for outpatient management.

Delayed diagnosis of injury in pediatric trauma.

OBJECTIVE: To define the frequency and nature of delayed diagnosis of injury (DDI) in pediatric trauma. DESIGN: Retrospective review. SETTING: Tertiary pediatric trauma center. METHODS: Medical records of 1175 pediatric trauma admissions from July 1, 1989, through June 30, 1992, were reviewed. RESULTS: Fifty (4.3%) patients had 53 DDI. Fractures accounted for 38 DDI, most commonly of the extremities (total, 16). The delay until injury diagnosis ranged from 1 to 55 (median, 3) days. Patients with DDI had lower scores on the Glasgow Coma Scale, higher injury severity scores, and longer pediatric intensive care unit and hospital stays than patients without DDI. Patients with DDI more frequently required medical transport, emergent intubation, admission to the pediatric intensive care unit, and surgery. The DDI altered treatment for 68% of patients; 10 required surgery, including second operations for 6 children. CONCLUSIONS: DDI represents a failure of pediatric trauma care at all levels. The severely injured child is at the greatest risk of DDI. All pediatric patients with trauma warrant ongoing evaluation to identify initially unrecognized injuries.

Pediatric basilar skull fracture: do children with normal neurologic findings and no intracranial injury require hospitalization?

STUDY OBJECTIVE: To delineate complications in patients with basilar skull fractures (BSFs) and normal neurologic findings, including computed tomography (CT) scans without intracranial injury, and to assess the need for hospitalization. DESIGN: Retrospective chart review. PARTICIPANTS: All emergency department patients with the ED diagnosis or hospital discharge diagnosis of BSF. Patients were included if they had a clinical or radiographic diagnosis of BSF. A subgroup of patients ("simple BSF") with normal neurologic examination findings in the ED, Glasgow Coma Scale scores of 15, and cranial CT scans without intracranial pathology was specifically analyzed. RESULTS: We included 239 patients in the study. One hundred fourteen patients (48%) were included in the "simple BSF" subgroup. In this subgroup, vomiting (6%) was the most common complication, meningitis (1%) the most serious. There were no cases of delayed intracranial hemorrhage, and no patient with "simple BSF" required surgery. CONCLUSION: Given the relatively low frequency of serious complications, our study suggests that some patients with BSFs may not require hospital admission.

Felbamate overdose: a case report and discussion of a new antiepileptic drug.

Felbamate was approved in July 1993 for use alone or in combination with other antiepileptic drugs for partial seizures and Lennox-Gastaut syndrome. We report an overdose of felbamate in a teenage female patient who, in a suicide gesture, ingested eight times her maximum dose and suffered only mild side effects. This first report of a felbamate overdose is presented and followed by a discussion of felbamate's effectiveness, pharmacology, adverse effects, and drug interactions.

Fluoroscopic foley catheter removal of esophageal foreign bodies in children: experience with 415 episodes.

OBJECTIVE: This study sought to investigate the safety and efficacy of the fluoroscopic Foley catheter technique (FFCT) for removal of esophageal foreign bodies (EEBs) in children, and to identify factors associated with decreased success. DESIGN/SETTING/PATIENTS: An 11-year retrospective review of all pediatric patients undergoing the FFCT for removal of EFBs at a tertiary-care children's hospital was performed. RESULTS: Four-hundred and fifteen cases are reported. The median age was 29 months (range, 4 to 193); children < or = 24 months accounted for 45% (185) of the cases. Of all episodes 86% (355) involved children without known esophageal pathology. Coins comprised 76% (316) of the EFBs. The FFCT was successful in 91% (378) of the cases. In the 60 episodes involving children with underlying esophageal pathology, the technique had an 83% success rate compared to 92% in children without known pathology (P < .05). There were 290 patients where the duration of impaction was known. The success rate was 96% if the duration was 3 days or less compared to 50% if the duration was longer (P < .0001). Though the overall success in children < or = 24 months was less than older children (88% vs 94%, P < .05), this effect disappeared when corrected for duration of impaction. Minor complications occurred in 2% of the episodes, and major complications were noted in 1%. CONCLUSIONS: The FFCT appears to be a safe and effective method for removal of EFBs especially in children without underlying esophageal lesions and a duration of impaction < or = 3 days. Major complications are rare.

What dose of epinephrine is being used in pediatric resuscitation? Results of a survey.

Standard-dose epinephrine (SDE) currently recommended by the American Heart Association for pediatric resuscitation is 0.01 mg/kg (0.1 ml/kg of 1:10,000 solution). SDE has come under increasing scrutiny; many authors suggest that this dose is too small. We sought to determine current epinephrine dosing practices among physicians practicing pediatric emergency medicine. Half of the members of the American Academy of Pediatrics Emergency Medicine section, selected randomly, were surveyed by a mailed questionnaire. After two mailings, 105 of 162 surveys (65%) were completed by members in practice. Of the 105 responders, 59% described their practice as "pediatric emergency medicine"; 17% as "emergency medicine (children and adults)"; 10% as "general pediatric practice or clinic"; 10% as "critical care"; and 5% as "other." Fifty-one (49%) had completed fellowship training, and 81 (77%) were either PALS or APLS instructors (referred to as "instructors" below). Overall, 72% (76/105) indicated that they use doses larger than SDE. Sixty-five of these (86%) described their dosing practice as "recommended dose initially, then larger dose." Twenty-one percent use SDE less than half of the time, and 16% use a dose 10 to 20 times larger at least half of the time. No responder used doses smaller than SDE. Instructors were more likely to use larger doses than were noninstructors (83% compared with 38%; P < 0.001). In the instructor group, a significantly larger dose was being taught "informally" than "formally" (P < 0.001). This survey was undertaken to determine current dosing practices by a group of physicians who are knowledgeable and experienced in pediatric resuscitation, not to resolve the question of the optimal dose of epinephrine.(ABSTRACT TRUNCATED AT 250 WORDS)

Trampolines revisited: a review of 114 pediatric recreational trampoline injuries.

A search of the medical literature failed to reveal any articles that discuss pediatric injuries acquired on privately owned recreational trampolines. This study was undertaken to quantify and qualify pediatric injuries from recreational trampoline use. A group of 114 patients who presented to the Emergency Department at Primary Children's Medical Center in Salt Lake City, Utah, with injuries directly related to use of a trampoline are discussed. There was a 1.2:1 male-female ratio. The average age was 8.0 years. Forty-eight percent of the patients were injured on their family's trampoline, with the remainder injured on a friend's, neighbor's, relative's, or gymnasium's equipment. The majority of injuries involved group use of the trampoline and the youngest person in a group was most often the injured participant. Extremity injuries were seen in 55% of the patient and head or neck injuries in 37%. Seventy-five percent of the patients required radiographs, 23% hospitalization, and 17% operative intervention. The history of the trampoline and medical literature discussions concerning injuries and safety are reviewed.

Radial head subluxation: epidemiology and treatment of 87 episodes.

Radial head subluxation is a frequent upper-extremity injury in children. Through a prospective study of patients seen in the emergency department, the epidemiology and treatment were reviewed, and two methods of reduction were compared. During a nine-month period, there were 87 episodes of radial head subluxation in 83 children with six cases in infants 6 months old or younger. A pull mechanism of injury was not identified in 49% of the cases. Girls were seen more often than boys, the left arm was more frequently involved, and the incidence of recurrence was 26.7%. The two reduction methods did not differ significantly in their initial success rate. The presence of a click during a reduction attempt had a positive predictive value of 92% and a negative predictive value of 76%. Most children (76.8%) had return of arm use in less than ten minutes. Slow return of arm use (more than ten minutes) was not associated with delay in reduction but was associated with age of less than 2 years (P less than .001).

Pediatric coin ingestions. A prospective study of coin location and symptoms.

Coins are the most common esophageal foreign body in children. We prospectively evaluated 52 consecutive children who had swallowed coins to determine the incidence of asymptomatic esophageal coins and the rate of spontaneous passage. All patients had a roentgenogram; coins were removed from the esophagus if the patient was symptomatic. children with asymptomatic esophageal coins were allowed less than 24 hours to pass the coin to the stomach. Thirty children had esophageal coins; of these, 9 (30%) were asymptomatic. The presence of symptoms was significantly associated with esophageal coins, but the absence of symptoms did not reliably exclude the possibility of an esophageal coin. All children who swallow coins should undergo roentgenographic evaluation.
