Limb-Shaking TIA Presenting as Hemichorea-Hemiballismus: TIA Chameleons Diagnostic Challenge in the Emergency Department.

BACKGROUND: demonstrate the importance of considering limb-shaking syndrome in the differential diagnosis of patients who present to the emergency department (ED) with hyperkinetic movements. METHODS: In this article, we describe a diagnostic challenge in the ED in which a patient presents with hyperkinetic movements that are initially diagnosed as hemichorea-hemiballismus (HCHB) but are subsequently found to be limb-shaking syndrome with important therapeutic opportunities. RESULTS: Following a diagnosis of left carotid obstruction, the patient underwent left carotid endarterectomy 5 days after admission. Six months after surgery, the patient had no further symptoms, and an ultrasound scan and magnetic resonance angiography have confirmed no restenosis. CONCLUSION: Limb shaking is an uncommon form of transient ischemic attack that should be recognized and differentiated from conditions such as focal motor seizures. Recognition will almost invariably indicate carotid artery occlusion, and timely treatment may not only abolish the attacks in patients but also reduce their risk of stroke. HCHB represents a spectrum of hyperkinetic movement disorders varying in the severity of choreic and/or ballistic movements. The presented case includes limb-shaking syndrome in the differential diagnosis and prompts for further investigations to complete the assessment.

Comparison of the Canadian CT head rule and the New Orleans criteria in patients with minor head injury in a Spanish hospital. / Comparación de la regla canadiense y los criterios de New Orleans en el traumatismo craneal leve en un hospital español.

BACKGROUND AND OBJECTIVE: To compare two scales for assessment of patients with mild head injury. The Canadian CT Head Rule (CCHR) and New Orleans Criteria (NOC) according to their diagnostic accuracy in patients attending an emergency department, and to determine the most important predictive values. METHOD: Cross-sectional study in a first-level Hospital in the period of January 2011 to January 2013. Patients with mild head injury criteria were included. All the patients underwent a computed tomography (CT) of the head as part of internal protocol and the CCHR and NOC criteria were recorded for each patient. We consider the main variable the presence of traumatic lesions on CT and, as secondary variables, neurosurgical intervention and post-concussion syndrome. Sensitivity, specificity, predictive values and validity index (VI) of the CCHR and the NO criteria in the subgroup of patients with a Glasgow Coma Scale (GCS) score of 15 points were compared. RESULTS: A total of 217 patients, of whom 197 had a GCS score of 15 points were evaluated. Both rules showed 100% sensitivity when a significant injury was presented in the CT, the CCHR 100% (95% CI: 97.4%-100%) and the NO criteria 100% (95% CI: 97.4%-100%); but the CCHR achieved higher values of specificity 25.3% (95% CI: 18.6%-32%), positive predictive value (PPV) and VI. The two rules showed a 100% sensitivity regarding neurosurgical intervention; however the CCHR with high-risk criteria showed better specificity, PPV and VI 55.2 (95% CI: 8.3%-62.2%) compared to the NO criteria 7.6 (95% CI: 3.8%-11.5%). With regard to post-concussion syndrome criteria NO criteria showed better sensitivity 100% (95% CI: 96.2%-100%) and predictive values, but lower specificity and VI compared with the CCHR 76.9% (95% CI: 50.2%-100%). CONCLUSIONS: Our study demonstrates the high sensitivity of the CCHR and the NO criteria in patients with mild head injury, both to detect a significant clinical lesion on CT or the need for neurosurgical intervention and better specificity of CCHR compared with NO criteria. The adoption of clinical prediction rules, especially the CCHR, to request a CT scan in patients with mild head injury should be recommended in the emergency department.

Basic life support knowledge of secondary school students in cardiopulmonary resuscitation training using a song.

OBJECTIVES: To examine the effectiveness of a "cardiopulmonary resuscitation song" in improving the basic life support skills of secondary school students. METHODS: This pre-test/post-test control design study enrolled secondary school students from two middle schools randomly chosen in Córdoba, Andalucia, Spain. The study included 608 teenagers. A random sample of 87 students in the intervention group and 35 in the control group, aged 12-14 years were selected. The intervention included a cardiopulmonary resuscitation song and video. A questionnaire was conducted at three-time points: pre-intervention, one month and eight months post-intervention. RESULTS: On global knowledge of cardiopulmonary resuscitation, there were no significant differences between the intervention group and the control group in the trial pre-intervention and at the month post-intervention. However, at 8 months there were significant differences with a p-value = 0.000 (intervention group, 95% CI: 6.39 to 7.13 vs. control group, 95% CI: 4.75 to 5.92), F(1,120)=16.644, p=0.000). In addition, significant differences about students' basic life support knowledge about chest compressions at eight months post-intervention (F(1,120)=15.561, p=0.000) were found. CONCLUSIONS: Our study showed that incorporating the song component in the cardiopulmonary resuscitation teaching increased its effectiveness and the ability to remember the cardiopulmonary resuscitation algorithm. Our study highlights the need for different methods in the cardiopulmonary resuscitation teaching to facilitate knowledge retention and increase the number of positive outcomes after sudden cardiac arrest.

[Emergency department training on the appropriate prescription of anticoagulants in atrial fibrillation and on patient follow-up after discharge]. / Intervención en el servicio de urgencias para lograr un inicio y seguimiento adecuados de la anticoagulación en pacientes con fibrilación auricular.

OBJECTIVES: The main objective was to evaluate the effect of an emergency department training intervention on the use of a protocol for prescribing anticoagulant therapy in atrial fibrillation and on following patients after discharge. MATERIAL AND METHODS: Quasi-experimental pre-post study of a training intervention; the control patients were not matched but were selected consecutively before and after the intervention. All patients were over the age of 18 years, had atrial fibrillation identified by electrocardiogram, and indications for anticoagulant therapy, specifically a score of 2 or more on the CHADS2-DS2-VASc scale (cardiac failure, hypertension, age >75 years, diabetes, stroke [doubled], vascular disease, age 65-74 years, sex). The primary outcome was percentage of patients on anticoagulant therapy on discharge from the department. The secondary outcome was the percentage of patients on therapy 1 month after discharge. RESULTS: A total of 184 patients (86 before the intervention and 98 afterwards) were included. Training significantly increased the prescription of anticoagulants in the department (before the intervention, 32 patients [37%] vs 95 [97%] afterwards; P<.001). In the preintervention period, 26 patients (30% were on anticoagulants 1 month later; in the postintervention period, 26 (30%) were still on therapy (P<.001). CONCLUSION: This study shows that emergency staff training is effective for implementing protocols based on anticoagulant therapy guidelines.

OBJETIVO: Evaluar el resultado de una intervención formativa realizada en el servicio de urgencias (SU), en cuanto a la correcta prescripción y uso de un protocolo de anticoagulación en pacientes con fibrilación auricular (FA) y su posterior seguimiento. METODO: Estudio cuasi-experimental con un grupo de control no equivalente, pre/post intervención formativa. Se seleccionaron dos grupos de pacientes (pre y postintervención) mediante muestreo consecutivo, mayores de 18 años, que se presentaron en el SU con FA identificada en el ECG y con criterios de anticoagulación según la estratificación de riesgo de la escala CHA2DS2-VASc 2. El resultado primario fue la proporción de pacientes anticoagulados al alta del SU. El resultado secundario fue la proporción de pacientes anticoagulados al mes del alta del SU. RESULTADOS: Se incluyeron 184 pacientes (86 preintervención, 98 postintervención). La intervención aumentó de manera significativa el comienzo de la anticoagulación [preintervención 32 (37%) vs postintervención 95 (97%); p < 0,001] y el seguimiento al mes de comenzar el tratamiento [preintervención 26 (30%) vs postintervención 91 (93%); p < 0,001]. CONCLUSIONES: Una intervención formativa en el SU es efectiva para implementar los protocolos adaptados a las guías de práctica clínica de la anticoagulación.

Spontaneous splenic rupture and Anisakis appendicitis presenting as abdominal pain: a case report.

INTRODUCTION: Anisakidosis, human infection with nematodes of the family Anisakidae, is caused most commonly by Anisakis simplex. Acquired by the consumption of raw or undercooked marine fish or squid, anisakidosis occurs where such dietary customs are practiced, including Japan, the coastal regions of Europe and the United States. Rupture of the spleen is a relatively common complication of trauma and many systemic disorders affecting the reticuloendothelial system, including infections and neoplasias. A rare subtype of rupture occurring spontaneously and arising from a normal spleen has been recognized as a distinct clinicopathologic entity. Herein we discuss the case of a woman who presented to our institution with appendicitis secondary to Anisakis and spontaneous spleen rupture. CASE PRESENTATION: We report the case of a 53-year-old Caucasian woman who presented with hemorrhagic shock and abdominal pain and was subsequently found to have spontaneous spleen rupture and appendicitis secondary to Anisakis simplex. She underwent open surgical resection of the splenic rupture and the appendicitis without any significant postoperative complications. Histopathologic examination revealed appendicitis secondary to Anisakis simplex and splenic rupture of undetermined etiology. CONCLUSIONS: To the best of our knowledge, this report is the first of a woman with the diagnosis of spontaneous spleen rupture and appendicitis secondary to Anisakis simplex. Digestive anisakiasis may present as an acute abdomen. Emergency physicians should know and consider this diagnosis in patients with ileitis or colitis, especially if an antecedent of raw or undercooked fish ingestion is present. Spontaneous rupture of the spleen is an extremely rare event. Increased awareness of this condition will enhance early diagnosis and effective treatment. Further research is required to identify the possible risk factors associated with spontaneous rupture of the spleen.

A report of disseminated adenocarcinoma presenting as thrombotic thrombocytopenic purpura.

Thrombotic microangiopathies (TMAs) represent a heterogeneous group of diseases characterized by a microangiopathic hemolytic anemia, peripheral thrombocytopenia, and organ failure of variable severity. TMAs encompass thrombotic thrombocytopenic purpura (TTP), typically characterized by fever, central nervous system manifestations and hemolytic uremic syndrome (HUS), in which renal failure is the prominent abnormality. In patients with cancer TMAs may be related to various antineoplastic drugs or to the malignant disease itself. The reported series of patients with TMAs directly related to cancer are usually heterogeneous, retrospective, and encompass patients with hematologic malignancies with solid tumors or receiving chemotherapy, each of which may have distinct presentations and pathophysiological mechanisms. Patients with disseminated malignancy who present with microangiopathic hemolytic anemia and thrombocytopenia may be misdiagnosed as thrombotic thrombocytopenic purpura (TTP) Only a few cases of TTP secondary to metastatic adenocarcinoma are known in the literature. We present a case of a 34-year-old man with TTP syndrome secondary to metastatic small-bowel adenocarcinoma. Patients with disseminated malignancy had a longer duration of symptoms, more frequent presence of respiratory symptoms, higher lactate dehydrogenase levels, and more often failed to respond to plasma exchange treatment. A search for systemic malignancy, including a bone marrow biopsy, is appropriate when patients with TTP have atypical clinical features or fail to respond to plasma exchange.
