Differential diagnosis of abuse injuries in infants and young children.

A complete differential diagnosis is essential when assessing potential child abuse injuries. The differential diagnosis provides clinicians with the opportunity to compare injuries that might mimic abuse with actual abuse-related injuries. The differential diagnosis should delineate the injury type, injury site, instruments used, patterns, and the appearance of old or repeated injuries. This article discusses differential diagnoses that should be considered when evaluating injuries in infants and young children.

Factors associated with victimization of personnel in emergency departments.

OBJECTIVE: The purpose of this study was to identify the incidence of ED personnel victimization in Central Florida and examine its relationship to victims' reports of 3 factors: characteristics of the patient/perpetrator, characteristics of the personnel victimized, and characteristics of the ED environment. METHODS: Data were collected anonymously in a mail survey using 37 items from Mahoney's Emergency Department Victimization Questionnaire (EDVQ) and a demographic questionnaire. Chi square, Spearman's rank correlation coefficient, and Pearson's product moment correlation were used to describe frequencies, incidence, and their relationships to the variables studied. A sample of 226 of the 600 direct care personnel (37%) from 18 of the 19 hospital emergency departments in a tri-county area (95%) participated. RESULTS: The incidence of physical assault was reported to be 42% during the past year and 72% during the respondents' careers. Alcohol use was associated with incidence (1-tailed Pearson; P =.001). Verbal abuse was significantly higher on day shift (P =.043). The most desired environmental variable was 24-hour security attendants, available to 51.8% of the respondents. More than a fourth of the subjects reported that they had completed no coursework or had no continuing education in violence prevention. DISCUSSION: Respondents reported avoiding identification on duty, underreporting, postvictimization staff turnover, dissatisfaction with security, and the desire for every security provision listed. The goals of reducing the fears and victimization of ED personnel should become a priority within the health care system.

Organophosphates--a pediatric hazard.

These agents act as anticholinesterases. Signs of toxicity are: overactivity of the parasympathetic nervous system, nausea, vomiting, diarrhea, sweating, abdominal cramps and copious secretions. Large doses may cause sustained depolarization of the motor end plate, leading to muscular paralysis. Death may ensue from respiratory failure. The extensive and often careless use of insecticides, fungicides and pesticides makes organophosphates a particular pediatric hazard. Atropine and pralidoxime chloride are effective for therapy.

Masseter contracture and tachycardia causing termination of anesthesia.

A careful preoperative history can be helpful in detecting problems with previous anesthetic experiences. However, it has been found that in the patients who have developed a complete syndrome of malignant hyperthermia (MH), 30% had prior uneventful general anesthesia. It is therefore of extreme importance when delivering anesthesia to recognize the signs of MH early in order to initiate correct procedures to prevent the development of a fulminating crisis of MH.
