The treatment of acute pain and anxiety in children undergoing therapeutic and diagnostic procedures in the emergency department has improved dramatically in recent years. The availability of non-invasive monitoring devices and the use of short-acting sedative and analgesic medications enable physicians to conduct safe and effective sedation and analgesia treatment. In today's practice of pediatric emergency medicine, sedation and analgesia has been considered as the standard of care for procedural pain. In most pediatric emergency departments throughout North America, "procedural sedation and analgesia" treatment is being performed by non-anesthesiologists (qualified emergency physicians and nurses). In 2003, the Israel Ministry of Health published formal guidelines for pediatric sedation by non-anesthesiologists; this important document recognizes for the first time the need for pediatric sedation and analgesia in the operating room. We describe the basic principles of procedural sedation and analgesia in children and urge physicians working in pediatric emergency rooms in Israel to expand their knowledge and be more involved in the treatment of pediatric procedural pain.

Background: Intravenous recombinant tissue plasminogen activator therapy within 3 hours of stroke onset is a proven effective treatment for acute ischemic stroke.

Objectives: To assess the feasibility and safety of rt-PA[1] therapy for reperfusion in routine clinical practice in Israel, in a setting of a dedicated stroke unit.

Methods: Consecutive patients presenting within less than 3 hours of stroke onset were evaluated by an emergency physician and the neurology stroke team. After brain computerized tomography eligible patients were treated with intravenous rt-PA (0.9 mg/kg; maximum dose 90 mg) according to an in-hospital protocol corresponding to recommended criteria. Patients were admitted to the acute stroke unit. Safety and clinical outcome were routinely assessed. Re-canalization was assessed by serial transcranial Doppler.

Results: The study group comprised 16 patients, mean age 61 years (range 47–80 years), male to female ratio 10:6, whose median baseline National Institutes of Health stroke scale was 13 (range 6–24). They were treated within a mean door-to-CT time of 39 minutes (range 17–62 min), door-to-drug time 101 minutes (range 72–150), and stroke onset-to-drug time 151 minutes (range 90–180). There was an early improvement within 24 hours (of ≥ 4 points in the NIHSS[2] score) in 7 patients (44%) and no early deteriorations. There were no protocol deviations, no symptomatic intracranial hemorrhages, and no major systemic hemorrhage within 36 hours of rt-PA treatment. Three asymptomatic hemorrhagic transformations of the infarct were noted on routine follow-up brain CT associated with neurologic improvement. Outcome data were comparable to the National Institute of Neurological Disorders and Stroke rt-PA Stroke Study.

Conclusion: Intravenous rt-PA treatment within 3 hours of stroke onset in routine clinical practice in Israel is feasible and appears safe in the setting of a neurology stroke unit and team. Careful implementation of rt-PA therapy for selected patients in Israel is encouraged.

Background: Since the early 1970s testicular scintigraphy has been used to diagnose the cause of acute scrotal pain. The advent of Doppler sonography further enhances diagnosis by  providing simultaneous real-time scrotal imaging with superimposed testicular blood flow information.

Objectives: To assess the diagnostic value of Doppler sonography in patients with acute scrotal pain and scintigraphic findings suggestive of testicular torsion.

Methods: Seventy-five patients with acute scrotal pain underwent testicular scintigraphy and Doppler sonography. All patients who had scintigraphic findings suggestive of testicular torsion were included in the study and their files were retrospectively reviewed.

Results: Twenty-seven patients had scintigraphic findings suggestive of testicular torsion. Radionuclide scintigraphy accurately detected all cases of testicular torsion. However, abscess, hematoma, hydrocele and other conditions simulated testicular torsion on scintigraphy, lowering the test specificity. These pathologies were clarified by Doppler sonography that was 95% specific and 86% sensitive for testicular torsion.

Conclusions: Doppler sonography should be used as the first-line modality in the evaluation of patients with suspected testicular torsion. Scintigraphy should be performed only in certain settings of equivocal sonographic findings to prevent false negative sonographic diagnosis.
 

Background: In the emergency department the physician is often confronted with the decision of where to hospitalize a patient presenting with chest pain and a possible acute myocardial infarction – in the cardiac care unit or in the internal medicine ward.

Objective: To characterize the clinical factors involved in the triage disposition of patients hospitalized with AMI[1] in Israel to either CCUs[2] or IMWs[3] and to determine to what extent the perceived probability of ischemia influenced the disposition decision.

Methods: During a 2 month nationwide prospective survey in the 26 CCUs and 82 of the 94 IMWs in Israel, we reviewed the charts of 1,648 patients with a discharge diagnosis of AMI. The probability of ischemia at admission was determined retrospectively by the Acute Coronary Ischemia Time-Insensitive Predictive Instrument. Co-morbidity was coded using the Index of Coexistent Diseases.

Results: The ACI-TIPI[4] score for patients admitted to CCUs or to IMWs was 76.2% and 57.7% respectively (P < 0.001). Multivariate analysis showed that young patients with a high probability of ischemia and low co-morbidity or functional impairment were more likely to be hospitalized in CCUs than in IMWs.

Conclusion: In Israel, the factors that strongly influence the initial triage disposition of patients with AMI to CCUs or IMWs are age, perceived probability of ischemia, status of co-morbid conditions and functional impairment.

Background: Acute myocardial infarction is rare in people under the age of 30.

Objective: To determine the clinical features and outcome in young patients presenting with AMI.

Methods: All patients aged 30 years and younger hospitalized with AMI during a period of 8 years (1993–2000) were evaluated for clinical features and outcome.

Results: Of the 3,758 patients with AMI, 15 were 30 years old or younger (0.4%). The mean age was 28 (range 21–30 years) and all were male. Eight had normal coronary arteries on angiogram; seven had obstructive coronary artery disease. Patients with OCA[1] had more classical risk factors for coronary disease. A complete diagnostic work-up was abnormal in four patients with NCA[2]: thrombophilia in two patients, spasm due to alcohol withdrawal and hyperthyroidism in one patient each. All patients presented with typical new-onset chest pain. None had a previous history of angina. All patients with OCA received reperfusion therapy as compared to one patient with NCA. Peak creatine phosphokinase in NCA and OCA was 504 ± 547 and 1,328 ± 440 respectively (P < 0.01). All patients with NCA had good left ventricular function on follow-up echocardiography, compared to only three in the OCA group (P = 0.02). There was one death due to cardiogenic shock in a patient with OCA. Follow-up of 4 ± 2 years demonstrated recurrent acute coronary syndromes in four of seven patients with OCA versus none in the NCA patients (P = 0.02).

Conclusions: AMI is rare in very young patients, and more than half have NCA. A thrombophilic tendency or spasm should be considered. Young patients with NCA have an excellent prognosis.
