Hiding in plain sight: Diagnosing pleural tuberculosis using lung ultrasound.

INTRODUCTION: Diagnosing pleural tuberculosis can be difficult in patients with ambiguous presentation, especially in resource-limited health centres. Thus, lung ultrasound had been studied as a novel method in helping clinicians to diagnose this condition. CASE PRESENTATION: A 48-year-old woman presented with worsening dyspnoea and orthopnoea for one week. She had also experienced weight loss, minimal dry cough and right-sided pleuritic chest pain for several weeks. A chest radiograph showed a right lower zone pleural effusion with no apparent lung consolidation. Lung ultrasound showed a right apical consolidation and right lower zone septated pleural effusion. Pleural fluid investigations showed exudative features of mixed lymphocytic, mesothelial and neutrophilic cellular components. Tuberculin skin test was strongly positive. She was subsequently treated for pleural tuberculosis. One month after treatment, her symptoms had improved considerably. DISCUSSION: Lung ultrasound has been found to be more effective than chest radiograph in detecting consolidation and diagnosing pneumonia. The portability and efficacy of today's ultrasound machines, including the handheld types, show that lung ultrasound is a practical, reliable and valuable diagnostic tool in managing pulmonary conditions including tuberculosis, provided that the operators are adequately trained. CONCLUSION: Lung ultrasound in tuberculosis is the next frontier for clinicians and researchers.

Transesophageal Echocardiography at the Golden Hour: Identification of Blunt Traumatic Aortic Injuries in the Emergency Department.

BACKGROUND: Although surface sonography has become an essential diagnostic tool in the evaluation of trauma patients, important limitations of this modality include the evaluation of retroperitoneal hemorrhage and mediastinal pathology, such as blunt traumatic aortic injuries (BTAI). As in other emergency applications where surface sonography can't provide the information needed, focused transesophageal echocardiography (TEE) may represent a valuable diagnostic tool in the evaluation of hemodynamically unstable trauma patients with suspected thoracic pathology such as BTAI. CASE SERIES: We present a series of five cases that illustrate the diagnostic value of emergency physician-performed resuscitative TEE in the diagnosis of BTAI in patients presenting with blunt thoracic trauma. WHY SHOULD AN EMERGENCY PHYSICIAN BE AWARE OF THIS?: As the use of point-of-care TEE during resuscitation continues to expand in emergency medicine, the evaluation of patients with BTAI represents a novel application where this emerging modality can allow early diagnosis of these injuries in hemodynamically unstable patients.

Prevalence and associated factors of stress, anxiety and depression among emergency medical officers in Malaysian hospitals.

BACKGROUND: Demanding profession has been associated with poor psychological health due to multiple factors such as overworking hours and night shifts. This study is to determine prevalence and associated factors of depression, anxiety and stress among medical officers working at emergency department in Malaysian hospitals. METHODS: A cross-sectional study was conducted on 140 emergency department medical officers working at general hospitals from seven Malaysia regions. They were randomly selected and their depression, anxiety and stress level were measured by the 21-item Depression, Anxiety, Stress Scale. RESULTS: The highest prevalence was anxiety (28.6%) followed by depression (10.7%) and stress (7.9%). Depression, anxiety and stress between seven hospitals were not significantly different (P>0.05). Male medical officers significantly experienced more anxiety symptoms than female medical officers (P=0.0022), however depression and stress symptoms between male and female medical officers were not significantly different (P>0.05). Depression, anxiety and stress were not associated with age, working experience, ethnicity, marital status, number of shifts and type of system adopted in different hospitals (P>0.05). CONCLUSION: The prevalence of anxiety was high, whereas for depression and stress were considerably low. Gender was the only factor significantly associated with anxiety. Other factors were not associated with depression, anxiety and stress. Future research should aim to gain better understanding on unique factors that affect female and male medical officers' anxiety level in emergency setting, thus guide authorities to chart strategic plans to remedy this condition.

Intravenous parecoxib sodium as an analgesic alternative to morphine in acute trauma pain in the emergency department.

BACKGROUND: Parecoxib sodium is the first parenteral COX-2 inhibitor used for pain management licensed for postoperative pain. However, no study has assessed the usage of parecoxib for acute traumatic pain in the emergency department (ED). The objective of this study was to investigate a potential alternative analgesic agent in the ED by determining the mean reduction of pain score between acute traumatic pain patients who were administered with intravenous (IV) parecoxib sodium versus IV morphine sulfate. The onset of perceptible analgesic effect and side effects were also evaluated. METHODS: A randomized, double-blinded study comparing IV parecoxib 40 mg versus IV morphine at 0.10 mg/kg was conducted in adult patients presented with acute traumatic pain with numeric rating scale (NRS) of 6 or more within 6 hours of injury. Patients were randomized using a computer-generated randomization plan. Drug preparation and dispensing were performed by a pharmacist. Periodic assessment of blood pressure, pulse rate, oxygen saturation, and NRS were taken at 0, 5, 15, and 30 minute intervals after the administration of the study drug. The primary outcome was the reduction of NRS. Side effect and drug evaluation was conducted within 30 minutes of drug administration. RESULTS: There was no statistically significant difference in the reduction of mean NRS between patients in the IV parecoxib group or IV morphine group (P = 0.095). The mean NRS for patients treated with IV morphine were 7.1 at 0 minutes, 4.5 at 5 minutes, 3.1 at 15 minutes, and 2.0 at 30 minutes. Whereas mean NRS for patients who received IV parecoxib were 7.8 at 0 minutes, 5.7 at 5 minutes, 4.7 at 15 minutes, and 3.9 at 30 minutes. The onset of perceptible analgesic effects could be seen as early as 5 minutes. Dizziness was experienced in 42.9% of patients who received IV morphine compared to none in the parecoxib group. CONCLUSIONS: There was non-significant trend toward superiority of IV morphine over IV parecoxib. Looking at its effectiveness and the lack of opioid-related side-effects, the usage of IV parecoxib sodium may be extended further to a variety of cases in the ED.
