The diagnosis of ovarian torsion remains challenging. Clinical characteristics lack sensitivity and specificity and ultrasound diagnosis is not definitive. Laparoscopy remains the investigation of choice. Despite delays in diagnosis this study demonstrates relatively high ovarian salvage rates compared with most published data.

Introduction:Recent events have brought disaster medicine into the public focus. Both the government and communities expect hospitals to be prepared to cope with all types of emergencies. Disaster simulations are the traditional method of testing hospital disaster plans, but a recent, comprehensive, literature review failed to find any substantial scientific data proving the benefit of these resource and time-consuming exercises.Objectives:The objective of this study was to test the hypothesis that an audiovisual presentation of the hospital disaster plans followed by a simulated disaster exercise and debriefing improved staff knowledge, confidence, and hospital preparedness for disasters.Methods:A survey of 50 members of the medical, nursing, and administrative staff were chosen from a pool of approximately 170 people likely to be in a position of responsibility in the event of a disaster.The pre-intervention survey tested factual knowledge as well as perceptions about individual and departmental preparedness. Post-intervention, the same 50 staff members were asked to repeat the survey, which included additional questions establishing their involvement in the exercise.Results:There were 50 pre-intervention tests and 42 post-intervention tests. The intervention resulted in a significant improvement in test pass rate: preintervention pass rate 9/50 (18%, 95% confidence interval ((CI) = 16.1–19.9%) versus post-intervention pass rate 21/42 (50%, 95% CI = 42.4–57.6%; X2 test, p = 0.002). Emergency department (ED) staff had a stronger baseline knowledge than non-ED staff: ED pre-test mean value for scores = 12.1 versus nonED scores of 6.2 (difference 5.9, 95% CI = 3.3–8.4); t-test, p <0.001. Those that attended >1 component had a greater increase in mean scores: increase in mean attendees was 5.6, versus the scores of non-attendees of 2.7 (difference 2.9, 95% CI = 1.0–4.9); t-test, p = 0.004. There was no significant increase in the general perception of preparedness. However, the majority of those surveyed described the exercise of benefit to themselves (53.7%,95% CI = 45.5–61.8%) and their department (63.2%, 95% CI = 53.5–72.8%).Conclusions:The disaster exercise and educational process had the greatest benefit for individuals and departments involved directly. The intervention also prompted enterprise-wide review, and an upgrade of disaster plans at departmental levels. Pre-intervention knowledge scores were poor. Post-intervention knowledge base remained suboptimal, despite a statistically significant improvement. This study supports the widely held belief that disaster simulation is a worthwhile exercise, but more must be done. More time and resources must be dedicated to the increasingly important field of hospital disaster preparedness.

In motor vehicle crash fatalities, most victims who die before reaching hospital do so because of major injury, with the head and chest the commonest regions involved. A large proportion of these injuries could be considered unsurvivable regardless of treatment. Earlier intervention or retrieval of such patients is unlikely to influence outcome in the majority of cases.

Glyphosate surfactant herbicide (GlySH) toxicity is an uncommon poisoning. We report two fatalities involving suicidal ingestion of this herbicide. Both deaths occurred despite early recognition of the serious nature of the poisoning and aggressive treatment. The deaths in this series are analysed in the context of a review of existing literature. Although traditionally regarded as minimally toxic, many deaths have been reported following suicidal ingestion. Severe GlySH toxicity may be refractory even to the most intensive supportive care. The triad of pulmonary oedema, metabolic acidosis and hyperkalaemia portends poor outcome. While containing a carbon phosphorus moiety, GlySH does not exhibit organophosphate toxicity. A clinical guide to assessing severity of GlySH toxicity is proposed and treatment modalities discussed.

The current study found that patients with musculoskeletal problems seen by a primary practitioner physiotherapy service had improved waiting times and length of stay relative to ACEM and Victorian Department of Health targets, and though constrained by a retrospective non-randomised design, to a similar group of patients seen by medical staff. Further evaluation of the physiotherapy practitioner service is required.

This finding justifies compulsory viewing of the video in the registrar orientation package locally and might encourage more widespread use of educational video in hospital disaster preparedness.

A more complete blockade is achieved earlier using the US-assisted technique. The US-assisted technique will become the technique of choice for FNB in this department.

ImportanceThe administration of a high fraction of oxygen following return of spontaneous circulation in out-of-hospital cardiac arrest may increase reperfusion brain injury.ObjectiveTo determine whether targeting a lower oxygen saturation in the early phase of postresuscitation care for out-of-hospital cardiac arrest improves survival at hospital discharge.Design, Setting, and ParticipantsThis multicenter, parallel-group, randomized clinical trial included unconscious adults with return of spontaneous circulation and a peripheral oxygen saturation (Spo2) of at least 95% while receiving 100% oxygen. The trial was conducted in 2 emergency medical services and 15 hospitals in Victoria and South Australia, Australia, between December 11, 2017, and August 11, 2020, with data collection from ambulance and hospital medical records (final follow-up date, August 25, 2021). The trial enrolled 428 of a planned 1416 patients.InterventionsPatients were randomized by paramedics to receive oxygen titration to achieve an oxygen saturation of either 90% to 94% (intervention; n = 216) or 98% to 100% (standard care; n = 212) until arrival in the intensive care unit.Main Outcomes and MeasuresThe primary outcome was survival to hospital discharge. There were 9 secondary outcomes collected, including hypoxic episodes (Spo2 &amp;lt;90%) and prespecified serious adverse events, which included hypoxia with rearrest.ResultsThe trial was stopped early due to the COVID-19 pandemic. Of the 428 patients who were randomized, 425 were included in the primary analysis (median age, 65.5 years; 100 [23.5%] women) and all completed the trial. Overall, 82 of 214 patients (38.3%) in the intervention group survived to hospital discharge compared with 101 of 211 (47.9%) in the standard care group (difference, −9.6% [95% CI, −18.9% to −0.2%]; unadjusted odds ratio, 0.68 [95% CI, 0.46-1.00]; P = .05). Of the 9 prespecified secondary outcomes collected during hospital stay, 8 showed no significant difference. A hypoxic episode prior to intensive care was observed in 31.3% (n = 67) of participants in the intervention group and 16.1% (n = 34) in the standard care group (difference, 15.2% [95% CI, 7.2%-23.1%]; OR, 2.37 [95% CI, 1.49-3.79]; P &amp;lt; .001).Conclusions and RelevanceAmong patients achieving return of spontaneous circulation after out-of-hospital cardiac arrest, targeting an oxygen saturation of 90% to 94%, compared with 98% to 100%, until admission to the intensive care unit did not significantly improve survival to hospital discharge. Although the trial is limited by early termination due to the COVID-19 pandemic, the findings do not support use of an oxygen saturation target of 90% to 94% in the out-of-hospital setting after resuscitation from cardiac arrest.Trial RegistrationClinicalTrials.gov Identifier: NCT03138005
