Torsion of the testicle: it is time to stop tossing the dice.

Abstract In this review, long-held myths and misperceptions about the evaluation and management of testicular torsion are discussed, and recommendations for the management of patients who present with acute scrotal pain are presented.

Neuromuscular blockade after ingestion of tree tobacco (Nicotiana glauca)

Two patients presented with life-threatening motor paresis after ingestion of leaves from the tree tobacco plant (Nicotiana glauca ). In addition to severe muscle weakness, bulbar palsies, flexor muscle spasm, hypertension, nausea, vomiting, and respiratory compromise were reported or observed. These are the fourth and fifth reported cases of a toxicologic emergency apparently caused by the alkaloid, anabasine, an isomer of nicotine found in the tobacco tree plant. The effects of this plant ingestion can mimic other better-known causes of paresis or paralysis. In areas of the country where the plant is indigenous, this toxicologic condition should be considered in the differential diagnosis of patients presenting with paresis or paralysis.

Spiral tibial fractures of children: A commonly accidental spiral long bone fracture

Pediatric training in child abuse has consistently emphasized a strong association between nonaccidental injuries and spiral fractures of long bones. Isolated spiral tibial fractures of childhood have previously been recognized by the orthopedic specialty to most frequently be accidental in etiology. The authors present evidence that supports a predominantly accidental etiology for isolated spiral tibial fractures of young children. This article presents a series in which 9 of 10 such spiral fractures were most likely the result of an accident and not child abuse or gross neglect. Additionally, almost all of these fractures presented as a gait disturbance and should be included in the differential of this complaint.

Treatment of Headaches in the ED With Lower Cervical Intramuscular Bupivacaine Injections: A 1-Year Retrospective Review of 417 Patients

Objective.—The primary objective of this retrospective chart review is to describe 1 years experience of an academic emergency department (ED) in treating a wide spectrum of headache classifications with intramuscular injections of 0.5% bupivacaine bilateral to the spinous process of the lower cervical vertebrae.

Childhood accidental spiral tibial (CAST) fractures.

OBJECTIVE To further define and describe the spectrum of presentations for accidental spiral tibial fractures of childhood. DESIGN A retrospective review. METHODS Children 8 years of age or younger who had sustained a tibial fracture within the last five or ten years were collected from the patient populations of two large tertiary medical centers in Southern California, Riverside General Hospital (RGH) and Loma Linda University Medical Center (LLUMC). A total of 189 tibial fractures were documented from both locations. Of the 189 patients, the 55 children with isolated spiral tibial fractures and no criteria for exclusion were selected for further review and analysis. These patients were reviewed for age at time of injury, gender, specific extremity involved, mechanism of injury, fracture location, degree of displacement, and whether child protective services involvement occurred. RESULTS Patients with isolated spiral tibial fractures ranged in ages from 12 months to 94 months (7 years 10 months). The mean age was 50.7 months. Eighteen (32.7%) of the patients were less than or equal to 36 months of age. No patient was under one year of age. Males (38/55 or 69%) sustained the fracture slightly more frequently than females. The right extremity was injured slightly less frequently (45.5%) than the left extremity (54.5%). Overall, the lower two thirds of the tibia contained the fracture in 95% of the injuries. Displacement of the fracture segments was most frequently none or minimal. While Child Protective Service referrals or investigations were not accomplished on the majority of the children, no injury was confirmed to have occurred as a result of non-accidental trauma. CONCLUSION Isolated spiral tibial fractures are a common injury of children less than 8 years of age and are most frequently accidental. The original description of a distinct clinical entity matching the original definition of the toddlers fracture does not appear to exist. Instead, the previously defined toddlers fracture is simply part of a spectrum of presentations of childhood accidental spiral tibial, or CAST, fractures. Consequently, our findings further support new nomenclature suggested for this fracture (1, 2).

Tibial fractures of young children

Tibial fractures are relatively frequent injuries of young children. These fractures are occasionally the cause of a childhood gait disturbance. Additionally, tibial fractures may be the result of child abuse. Consequently, the pediatrician should have knowledge concerning these injuries. In this paper, we present a review of tibial fractures in hospitalized children and describe their associations with nonaccidental trauma (NAT). Finally, we provide suggestions for improving nomenclature clarity for isolated spiral fractures of the tibia.

Emergency department presentation and management of pediatric heart transplant recipients.

The object of this study was to review and delineate the presenting complaints, signs, symptoms, and Emergency Department (ED) management of pediatric heart transplant recipients who presented to Loma Linda University Medical Centers (LLUMC) Emergency Department. A retrospective chart review was made of all of the pediatric heart transplant patients who presented to the ED at LLUMC from January 1986 through February 1993. The department is part of a 600-bed university hospital with an associated 250-bed childrens hospital that includes a pediatric heart transplant center and an ED that sees over 38,000 patients per year. The retrospective review collected information relating to chief complaint, physical findings, laboratory analysis, and diagnoses. Forty-seven patients (23%) presented to the ED for a total of 76 visits. The patients presented a median of 278 days (range 19 days to 6.5 years) after transplantation. The most common chief complaints were related to the respiratory tract, and the most common diagnoses (55%) were related to infectious processes. Fever was present in 21% of the visits. Three of 13 blood cultures obtained were positive. Cardiac symptoms were present in 14% of the visits with two rejection episodes. Hospital admission was required for 22 (29%) of the ED visits. Results showed that pediatric heart transplant recipients are most likely to present to the ED with infections. Although infections from opportunistic organisms and bacteremia must be considered, most infections are similar to those in the nontransplanted child. Life-threatening conditions such as graft rejection are less likely. Nevertheless, the emergency physician should maintain caution in the evaluation of these patients. Close cooperation and consultation with the transplant team will assure the optimal outcome for these patients.

Testicular torsion following orchiopexy

A case of testicular torsion one year after orchiopexy is presented. The occurrence of testicular torsion following surgery is a rare event which has the potential for diagnostic misadventures. To better delineate this condition, we performed a literature review of all reported cases of recurrent testicular torsion. Thirteen reported patients with testicular torsion following orchiopexy are presented and discussed.

Do pediatric headaches respond to bilateral lower cervical paraspinous bupivacaine injections

Objective: Bilateral lower cervical paraspinous intramuscular bupivacaine injections have recently been reported as a therapeutic modality for headache pain in adult patients presenting to an emergency department. In this study, we accomplished a retrospective review of all pediatric patients with headaches who were treated with this technique in an emergency department setting over a 16-month period. The therapeutic response of all pediatric patients who received bilateral lower cervical paraspinous intramuscular bupivacaine injections for headache pain is described in this article. Methods: Three separate databases were reviewed to capture all patients younger than 18 years with a diagnosis of headache who received bilateral cervical injections between June 30, 2003, and December 1, 2004, in the Medical College of Georgia and Childrens Medical Center emergency departments. Their medical records were retrospectively reviewed to determine their response to this procedure. Results: The headaches of 13 patients younger than 18 years were treated with this procedure. The mean headache severity was 9.15, and the mean duration of headache was 3.16 days. Six (46.2%) of 13 patients had complete relief of their headaches, whereas 5 (38.4%) of 13 patients had partial relief. No significant relief was documented in 2 (15.4%) of 13 patients. A therapeutic response was documented in 11 (84.6%) of 13 of the patients. Conclusions: These retrospective observations suggest that bilateral lower cervical paraspinous intramuscular injections with small amounts of bupivacaine may have a therapeutic role in the management of headache pain in children, and their rate of therapeutic response may be similar to that recently reported for adult headache patients.

Pediatric laryngoscope blade size selection using facial landmarks.

Objectives: The study evaluates whether facial landmarks can be used to estimate an appropriate laryngoscope blade length for oral endotracheal intubation in children. We tested the hypothesis that the laryngoscope blade measuring 10 mm or less distal or proximal to the angle of the mandible (when the flat portion of the blade follows the facial contour from the upper incisor teeth to the angle of the mandible) will demonstrate greater success and ease of oral tracheal intubation. Methods: We performed an observational study that prospectively evaluated a convenience sample of children 8 years old or younger and who were undergoing direct laryngoscopy for oral endotracheal intubation in the operating room, outpatient surgery center, emergency department, or pediatric intensive care unit of a tertiary referral medical center. Ease and success of oral tracheal intubation were compared with distance measurements from the angle of the mandible to the tip of the laryngoscope blade. Results: Blade lengths considered too short (blade lengths >10 mm proximal to the angle of the mandible) were more likely to be associated with more than 1 attempt at intubation. Only 57.1% (12/21; 95% confidence interval [CI], 36.5-75.5) of the intubations using the shorter blade were performed on the first attempt as compared with 89.7% (26/29; 95% CI, 73.6-96.4) of the intubations using the recommended length or 85.7% (6/7; 95% CI, 48.7-97.4) of the intubations using blades extending longer than 10 mm past the angle of the mandible. Conclusions: The distance from the upper incisor teeth to the angle of the jaw seems to be an excellent clinical landmark for laryngoscope blade length selection for pediatric intubations. When the blade (excluding the handle insertion block) is placed at the upper midline incisor teeth and the tip is located within 1 cm proximal or distal to the angle of the mandible, oral tracheal intubations are more consistently accomplished on the first attempt. Our observations suggest that facial landmarks can be used to estimate an appropriate laryngoscope blade length for oral endotracheal intubation in children.
