Background: Wandering spleen is a rare entity that may pose a surgical emergency following torsion of the splenic vessels, mainly because of a delayed diagnosis. Complications after surgery for wandering spleen may necessitate emergency treatment.

Objectives: To describe the clinical course and treatment for children who underwent emergency surgeries for wandering spleen at a tertiary pediatric medical center over a 21 year period and to indicate the pitfalls in diagnosis and treatment as reflected by our experience and in the literature.

Methods: The database of a tertiary pediatric medical center was searched retrospectively for all children who underwent emergency treatment for wandering spleen between 1996 and 2017. Data were collected from the medical files. The relevant literature was reviewed.

Results: Of ten patients who underwent surgery for wandering spleen during the study period, five underwent seven emergency surgeries. One patient underwent surgery immediately at initial presentation. In the other four, surgical treatment was delayed either due to misdiagnosis or for repeated imaging studies to confirm the diagnosis. Emergency laparotomy revealed an ischemic spleen in all patients; splenectomy was performed in two and the spleen was preserved in three. Four of the seven emergency operations were performed as the primary surgery and three were performed to treat complications.

Conclusions: Wandering spleen should ideally be treated on an elective or semi-elective basis. Surgical delays could be partially minimized by a high index of suspicion at diagnosis and by eliminating unnecessary and time-consuming repeated imaging studies.

Background: Acute musculoskeletal pain is one of the most commonly reported symptoms among patients visiting the emergency department (ED). Treatment with over-the-counter pain medications, given by nurses, results in improved pain management and reduces the waiting time to drug administration without significant side effects. Opioid analgesics are extensively used for acute pain in the ED. Compared to morphine, oxycodone has a much more specific pharmacological activity, higher analgesic potential, and more tolerable side effects.

Objectives: To assess the degree of pain reduction using different protocols, including dypirone and oxycodone given by nurses, in treating acute musculoskeletal pain in the emergency department (primary outcome) and to evaluate the need for rescue medications (secondary outcome).

Methods: This observational prospective clinical trial compared two groups of 50 patients, each one visiting the ED due to musculoskeletal pain. One group was treated with dipyrone syrup and the other was treated with oxycodone syrup. The primary outcome was pain reduction measured by the Numeric Rating Scale (NRS). The secondary outcome was the difference in need for rescue medications.

Results: The reduction in the NRS was greater in the patients treated with oxycodone. This finding was statistically and clinically significant (P < 0.001). The need for rescue medications was also significantly reduced in this group of patients (P = 0.007).

Conclusions: This study showed that the administration of over-the-counter oxycodone syrup by nurses decreases the post-treatment pain reported by patients, reduces the need for rescue medications, and increases the satisfaction of the medical staff.

Background: When a patient arrives at the emergency department (ED) presenting with symptoms of acute decompensated heart failure (ADHF), it is possible to reach a definitive diagnosis through many different venues, including medical history, physical examination, echocardiography, chest X-ray, and B-type natriuretic peptide (BNP) levels. Point-of-care ultrasound (POCUS) has become a mainstream tool for diagnosis and treatment in the field of emergency medicine, as well as in various other departments in the hospital setting. Currently, the main methods of diagnosis of ADHF using POCUS are pleural B-lines and inferior vena cava (IVC) width and respiratory variation.

Objectives: To examine the potential use and benefits of bedside ultrasound of the jugular veins in the evaluation of dyspneic patients for identification of ADHF.

Methods: A blood BNP level was drawn from each participant at time of recruitment. The area and size of the internal jugular vein (IJV) during inspiration and expiration were examined.

Results: Our results showed that the respiratory area change of the IJVs had a specificity and sensitivity of nearly 70% accuracy rate in indentifying ADHF in our ED.

Conclusions: Ultrasound of the IJV may be a useful tool for the diagnosis of ADHF because it is easy to measure and requires little skill. It is also not affected by patient body habitus.

Background: Opinions differ as to the need of a lateral radiograph for diagnosing community acquired pneumonia in children referred to the emergency department. A lateral radiograph increases the ionizing radiation burden but at the same time may improve specificity and sensitivity in this population.

Objectives: To determine the value of the frontal and lateral chest radiographs compared to frontal view stand-alone images for the management of children with suspected community acquired pneumonia seen in a pediatric emergency department.

Methods: Chest radiographs from 451 children with clinically suspected pneumonia were retrospectively reviewed. Interpretation of frontal views was compared to interpretation of combined frontal and lateral view, the latter being the gold standard.

Results: Findings consistent with bacterial pneumonia were diagnosed in 94 (20.8%) of the frontal stand-alone radiographs and in 109 (24.2%) of the combined frontal and lateral radiographs. The sensitivity, specificity, positive predictive value, and negative predictive value of the frontal radiograph alone were 86.2%, 93.9%, 81.7%, and 95.5%, respectively. False positive and false negative rates were 15% and 21%, respectively, for the frontal view alone. The number of lateral radiographs needed to diagnose one community acquired pneumonia was 29.

Conclusions: The lateral chest radiograph improves the diagnosis of pediatric community acquired pneumonia to a certain degree and may prevent overtreatment with antibiotics.

Background: Outcomes of patients with acute ST-elevation myocardial infarction (STEMI) are strongly correlated to the time interval from hospital entry to primary percutaneous coronary intervention (PPCI). Current guidelines recommend a door to balloon time of < 90 minutes. 

Objectives: To reduce the time from hospital admission to PPCI and to increase the proportion of patients treated within 90 minutes. 

Methods: In March 2013 the authors launched a seven-component intervention program: 

1. Direct patient evacuation by out-of-hospital emergency medical services to the coronary intensive care unit or catheterization laboratory


2. Education program for the emergency department staff


3. Dissemination of information regarding the urgency of the PPCI decision


4. Activation of the catheterization team by a single phone call


5. Reimbursement for transportation costs to on-call staff who use their own cars


6. Improvement in the quality of medical records


7. Investigation of failed cases and feedback 

Results: During the 14 months prior to the intervention, initiation of catheterization occurred within 90 minutes of hospital arrival in 88/133 patients(65%); during the 18 months following the start of the intervention, the rate was 181/200 (90%) (P < 0.01). The respective mean/median times to treatment were 126/67 minutes and 52/47 minutes (P < 0.01). Intervention also resulted in shortening of the time interval from hospital entry to PPCI on nights and weekends. 

Conclusions: Following implementation of a comprehensive intervention, the time from hospital admission to PPCI of STEMI patients shortened significantly, as did the proportion of patients treated within 90 minutes of hospital arrival. 

 

Background: Deliberate self-harm (DSH) increases the danger of future suicide death and the risk increases with age. Self-harm in older adults is often associated with greater suicidal intent and lethality. 

Objectives: To investigate clinical and psychosocial variables of older patients (age ≥ 65 years) assessed due to DSH, compared with younger adults.

Methods: Patients admitted to the Emergency Department following DSH during an 8 year period were included.

Results: Of 1149 participants, 187 (16.6%) were older adults (age ≥ 65) and 962 (83.4%) were younger adults (< 65). The older adults reported DSH closer to mid-day (P < 0.01) and suffered more frequently from adjustment disorder and depression. Personality disorders and schizophrenia were less commonly diagnosed (P < 0.001). Prescription medication (sedatives and hypnotics) were a more frequent means (88% vs. 71%) of DSH among older patients. Younger patients with DSH used over-the-counter medications (21.9% vs. 6.4%) three times more than did the older patients (P < 0.01). Past DSH was significantly more frequent in younger adults. Following DSH the older patients were frequently admitted for further general hospitalization (P < 0.001). 

Conclusions: Older adults with DSH are a unique group with different clinical characteristics. There is a need for targeted prevention strategies and education of caregivers regarding DSH in older adults.

 

Background: Medical clowns are increasingly used for diminishing pain and anxiety during painful procedures being performed on children in the hospital setting. Cortisol levels rise as a response to emotional distress. 

Objectives: To investigate whether medical clown-assisted interventions to reduce child's distress during venipuncture have an effect on cortisol levels. 

Methods: During a 1 year period, children requiring blood work or intravenous access in the pediatric emergency department were prospectively randomized to either the presence or absence of a medical clown during the procedure. The child's distress was evaluated using the Faces Pain Scale - revised (FPS-R) for the 4–7 year age group and the visual analog scales (VAS) for those aged 8–15 years. Serum cortisol levels were measured in blood samples obtained by venipuncture. 

Results: Fifty-three children aged 2–15 years were randomly assigned to the study group (with medical clown, n=29) or to the control group (without medical clown, n=24). Combined pain scores of the study group and control group were 2.2 and 7.5 respectively (P < 0.001). No difference in mean cortisol levels was found between the study group and the control group at all ages (16.4 µg/dl vs. 18.3 µg/dl, P = 0.65).

Conclusions: In this pilot study, medical clowns reduced the distress from venipuncture in children. No effect on cortisol levels was observed. 

Background: Pregnant women with acute abdominal pain pose a diagnostic challenge. Delay in diagnosis may result in significant risk to the fetus. The preferred diagnostic modality is magnetic resonance imaging (MRI), since ultrasonography is often inconclusive, and computed tomography (CT) would expose the fetus to ionizing radiation

Objectives: To describe the process in setting up an around-the-clock MRI service for diagnosing appendicitis in pregnant women and to evaluate the contribution of abdominal MR in the diagnosis of acute appendicitis.

Methods: We conducted a retrospective study of consecutive pregnant women presenting with acute abdominal pain over a 6 year period who underwent MRI studies. A workflow that involved a multidisciplinary team was developed. A modified MRI protocol adapted to pregnancy was formulated. Data regarding patients' characteristics, imaging reports and outcome were collected retrospectively. 

Results: 49 pregnant women with suspected appendicitis were enrolled. Physical examination was followed by ultrasound: when positive, the patients were referred for MR scan or surgery treatment; when the ultrasound was inconclusive, MR scan was performed. In 88% of women appendicitis was ruled out and surgery was prevented. MRI diagnosed all cases with acute appendicitis and one case was inconclusive. The overall statistical performance of the study shows a negative predictive value of 100% (95%CI 91.9–100%) and positive predictive value of 83.3% (95%CI 35.9–99.6%).

Conclusions: Creation of an around-the-clock imaging service using abdominal MRI with the establishment of a workflow chart using a dedicated MR protocol is feasible. It provides a safe way to rule out appendicitis and to avoid futile surgery in pregnant women.

Background: Plain abdominal radiographs are still performed as a first imaging examination to evaluate abdominal pain in the emergency department (ED), despite uncertainty regarding their utility.

Objectives: To describe the frequency and outcomes of the use of plain abdominal radiographs in the diagnosis of patients presenting with acute non-traumatic abdominal pain in the ED of a medical center. 

Methods: We retrospectively reviewed the records of patients presenting to the ED with acute abdominal pain during a 6 month period. Further imaging (computed tomography, ultrasonography), when performed, was compared with the abdominal radiography. 

Results: Of 573 consecutive patients, 300 (52%) underwent abdominal radiography. Findings were normal in 88% (n=264), non-specific in 7.3% (n=22), and abnormal in 4.7% (n=14). For those with normal results, no further imaging was ordered for 43% (114/264). Of the 57% (150/264) who had follow-up imaging, 65% (98/150) showed abnormal findings. In 9 (3%) of the 300 patients, abdominal radiography identified bowel perforations and obstructions, and treatment was provided without the need for further radiologic examination.

Conclusions: The use of plain abdominal radiography is still common despite the high rate of false positive results. Efforts are needed to decrease the indiscriminate use of radiography in patients presenting with abdominal symptoms.

 

Background: Extracorporeal membrane oxygenation (ECMO) may serve as a bridge to regain cardiac function in refractory resuscitation. However, its use has so far been limited owing to low availability, especially in emergency departments. 

Objectives: To describe two children with acute myocarditis successfully treated with ECMO in the emergency department of a tertiary pediatric medical center. 

Description: The children presented with vomiting, followed by rapid deterioration to cardiogenic shock that failed to respond to conservative treatment. Given the urgency of their condition and its presumably reversible (viral) etiology, treatment with ECMO was initiated in the department’s resuscitation room. 

Results: Outcome was excellent, and cardiac function remained normal throughout 6 and 10 months follow-up. 

Conclusions: Extracorporeal life support has enormous potential in the emergency department and warrants further assessment.  

Objectives: To examine the quality and accuracy of diagnoses recorded in the ED in order to appraise its potential utility as a guage of the population's medical needs.

Methods: Using the Delphi process, a preliminary list of health indicators generated by an expert focus group was transformed into a query to the Ministry of Health's database. In parallel, medical charts were reviewed in four hospitals to compare the handwritten diagnosis in the medical record with that recorded on the standard diagnosis "pick list" coding sheet. Quantity and quality of coding were assessed using explicit criteria.

Results: During 2010 a total of 17,761 charts were reviewed; diagnoses were not coded in 42%. The accuracy of existing coding was excellent (mismatch 1%–5%). Database query (2,670,300 visits to 28 hospitals in 2009) demonstrated potential benefits of these data as indicators of regional health needs.

Conclusions: The findings suggest that an increase in the provision of community care may reduce ED attendance. Information on ED visits can be used to support health care planning. A "pick list" form with common diagnoses can facilitate quality recording of diagnoses in a busy ED, profiling the population’s health needs in order to optimize care. Better compliance with the directive to code diagnosis is desired.
