Can we predict agitation in patients with suicide attempts in the emergency department?

Background: The agitation in patients presenting to the emergency department (ED) after suicide attempts is common and an important problem. Objective: To establish whether we can predict agitated patients among suicide attempt patients in ED. Methods: This is a cross-sectional observational study of adult suicide attempt events in ED. Information was collected prospectively on a specially designed data-collection form. Patients aged 16 years old and above who presented to the ED for care due to suicide attempts were included in the study. Suicide attempts were grouped as aggressive and non-aggressive attempts. Results: A total of 533 patients were included. Forty-three of these patients had agitation in ED (8%). Non-aggressive suicide attempts were referred to psychiatry services more than aggressive ones (73.6%, n=345 vs 32.8%, n=21, P<0.0001). Agitation in ED and being male increased aggressive suicide attempt risk 3.5 (95% CI:1.6-7.6) and 3.2 times (95% CI:1.8-5.5), respectively. Agitation was statistically more frequent among these patients: those on antidepressant overdose, with previous suicide attempt; with aggressive suicide attempt; and those with confusion; and unconsciousness (P<0.05). Conclusion: Patients who attempted suicide and whose risk of harm to others included those with: antidepressant overdose, aggressive suicide attempt and the unconscious. Response teams should be prepared for these subgroups.

Scrotal Exploration for Testicular Torsion and Testicular Appendage Torsion: Emergency and Reality

Background: Scrotal exploration is considered the procedure of choice for acute scrotum. Objectives: We evaluated the importance of early diagnosis and testicular salvage on the therapeutic outcomes of patients with pediatric testicular torsion (TT) and testicular appendage torsion (TAT) in our geographic area. Patients and Methods: We performed a retrospective database analysis of patients who underwent emergency surgery for TT or TAT between January 1996 and June 2009. Patient history, physical examination findings, laboratory test results, color Doppler sonography (CDS) results, and surgical findings were reviewed. Results: A total of 65 cases were included in our analysis. Forty-two cases were followed up for at least 3 months. Testicular tenderness was identified as the major clinical manifestation of TT, while only a few patients with TAT presented with swelling. CDS was an important diagnostic modality. The orchiectomy rate was 71% in the TT group. Conclusions: Cases of acute scrotum require attention in our area. Early diagnosis and scrotal exploration could salvage the testis or preserve normal function without the need for surgery.

Multi-drug resistant Staphylococcus aureus isolated from emergency ward of an Iranian hospital

Purpose: To study the prevalence of resistant strains of Staphylococcus aureus isolated from surfaces, beds and various equipment of an Iranian hospital emergency ward. Methods: Two hundred swab samples were collected from the surfaces, beds, trolleys, surgical equipment and diagnostic medical devices in emergency ward. Samples were cultured and those that were S. aureus-positive were confirmed using polymerase chain reaction (PCR). Antimicrobial resistance pattern was analyzed using disk diffusion method. Results: Nine of 200 samples (4.5 %) collected were positive for S. aureus. Surfaces (8.8 %), beds (5 %) and trolleys (5 %) were the most commonly contaminated. S. aureus isolates exhibited varying levels of resistance against antibiotics with the following being the highest: tetracycline (88.8 %), penicillin (88.8 %) and ampicillin (77.7 %). The prevalence of resistance against methicillin, oxacillin and azithromycin were 44.4, 33.3 and 33.3 %, respectively. There was no pattern of resistance against imipenem. Conclusion: Efficient disinfection of surfaces, beds, trolleys and surgical instruments should be performed periodically to reduce colonization of resistant strains of S. aureus in various areas of emergency health care centers.
