Presence of metallic components in transdermal drug delivery systems and risk of skin burns. / [Artículo traducido] Presencia de partículas metálicas en parches transdérmicos de medicamentos y riesgo de quemaduras.

OBJECTIVE: Skin burns are associated with the presence of metallic components in transdermal drug delivery systems during Magnetic Resonance Imaging, cardioversion or defibrillation procedures. The aim of the study was to review the presence of metallic components in marketed products of transdermal drug delivery systems in Spain. METHOD: For each presentation, the summary of product characteristics was reviewed. If the information was not provided, manufacturers were contacted. RESULTS: We identified 59 marketed products of transdermal drug delivery systems of 12 different active substances. 59.3% of patches contained metallic components or their presence could not be ruled out. Information regarding the need to remove the patch was only included in 8 summaries of product characteristics (13.6%). A table was elaborated and included the following aspects: product, active substance, manufacturer, need to remove the patch before the exposure to magnetic or electric fields and references. CONCLUSION: More than a half of the patches at the time of the study contained metals or their absence could not be confirmed by the manufacturer. However, this information was only included in 13.6% of summaries of product characteristics.

Appropriateness of Empirical Antibiotic Therapy for Cervicitis and Urethritis Prescribed in the Emergency Department.

Objectives: Sexually transmitted infections are a prevalent global health care problem. Treatment guidelines have recently been updated as a result of antimicrobial resistance and public health trends. The aim of the study was to assess the appropriateness of empirical antibiotic therapy prescribed for cervicitis and urethritis in the emergency department. Methods: We designed a retrospective observational cohort study. We included adult patients with suspected cervicitis or urethritis who attended the emergency department of a tertiary hospital in 2020. We excluded patients with suspected pelvic inflammatory disease, pregnancy or prostatitis and those requiring admission to hospital. Appropriateness of empirical antibiotic therapy was evaluated taking into account 4 aspects: indication, dosing, duration of therapy, and route of administration. Data were obtained from the electronic medical record, the electronic prescription program, and the discharge summary. Results: The study population comprised 176 patients; mean age was 28.9 years (SD = 7.7), and 90.9% were men. The most prescribed treatment was the combination of ceftriaxone and azithromycin (83.0%). Treatment was inappropriate in 71.6% of patients. A total of 159 drug errors were recorded. The most frequent cause was undertreatment (36.4%) related to underdosing (46.5%), particularly with regard to ceftriaxone. The percentage of errors was 11.9% for indication, 84.9% for dosing, 3.1% for duration, and 0% for route of administration. Conclusions: A high percentage of patients who attended the emergency department for suspected cervicitis or urethritis received an inappropriate empirical antibiotic regimen. The main reason was undertreatment due to underdosing.

Level of concordance between two risk-assessment models for predicting venous thromboembolism in medical patients at admission.

OBJECTIVES: To evaluate the level of concordance between the 2007 PRETEMED guidelines and the 2012 American College of Chest Physicians (ACCP) guidelines in medical patients at admission. METHODS: A cross-sectional, observational and descriptive study was designed and included all adult medical patients admitted from an emergency department. Firstly, patients classified as low-moderate risk and high risk according to PRETEMED were compared to those classified by ACCP as low and high risk. Secondly, the same analysis was performed but this time low and moderate-high risk patients according to PRETEMED were compared to ACCP low and high risk patients. The level of concordance was calculated using the kappa concordance index. The study was approved by the Ethics Committee for Clinical Research of the hospital. RESULTS: The analysis was performed with 207 patients; 53.1% were male and the median age was 75.3 years (minimum 18, maximum 100 years old). The most common diagnosis at admission was related to a respiratory disease (37.2%). The level of concordance was 0.59 (95% CI 0.48 to 0.70) when moderate risk patients were grouped with low-risk patients and 0.53 (95% CI 0.42 to 0.65) when moderate risk patients were grouped with high-risk patients. CONCLUSIONS: The level of concordance between both guides is moderate. It would be helpful to confirm whether the level of agreement improves when the patient's condition stabilises after several days of hospitalisation.

Usefulness of midregional proadrenomedullin to predict poor outcome in patients with community acquired pneumonia.

BACKGROUND: midregional proadrenomedullin (MR-proADM) is a prognostic biomarker in patients with community-acquired pneumonia (CAP). We sought to confirm whether MR-proADM added to Pneumonia Severity Index (PSI) improves the potential prognostic value of PSI alone, and tested to what extent this combination could be useful in predicting poor outcome of patients with CAP in an Emergency Department (ED). METHODS: Consecutive patients diagnosed with CAP were enrolled in this prospective, single-centre, observational study. We analyzed the ability of MR-proADM added to PSI to predict poor outcome using receiver operating characteristic (ROC) curves, logistic regression and risk reclassification and comparing it with the ability of PSI alone. The primary outcome was "poor outcome", defined as the incidence of an adverse event (ICU admission, hospital readmission, or mortality at 30 days after CAP diagnosis). RESULTS: 226 patients were included; 33 patients (14.6%) reached primary outcome. To predict primary outcome the highest area under curve (AUC) was found for PSI (0.74 [0.64-0.85]), which was not significantly higher than for MR-proADM (AUC 0.72 [0.63-0.81, p > 0.05]). The combination of PSI and MR-proADM failed to improve the predictive potential of PSI alone (AUC 0.75 [0.65-0.85, p=0.56]). Ten patients were appropriately reclassified when the combined PSI and MR-proADM model was used as compared with the model of PSI alone. Net reclassification improvement (NRI) index was statistically significant (7.69%, p = 0.03) with an improvement percentage of 3.03% (p = 0.32) for adverse event, and 4.66% (P = 0.02) for no adverse event. CONCLUSION: MR-proADM in combination with PSI may be helpful in individual risk stratification for short-term poor outcome of CAP patients, allowing a better reclassification of patients compared with PSI alone.

Factores predictivos de mortalidad en la gangrena de Fournier: serie de 59 casos / Predictive factors for mortality in Fournier’ gangrene: A serie of 59 cases

OBJETIVOS: La gangrena de Fournier (GF) es la fascitis necrosante del periné y área genital que presenta una elevada mortalidad. El objetivo es analizar los factores pronósticos de mortalidad, creación de una nueva escala predictiva de mortalidad y compararla con las ya validadas en los pacientes diagnosticados de GF en nuestro Servicio de Urgencias. MÉTODOS: Estudio analítico, retrospectivo entre 1998 y 2012. RESULTADOS: De los 59 casos, 44 sobrevivieron (74%) (S) y 15 fallecieron (26%) (E). Se encontraron diferencias significativas en la vasculopatía periférica (S 5 [11%]; E 6 [40%]; p = 0,023), hemoglobina (S 13; E 11; p = 0,014), hematocrito (S 37; E 31,4; p = 0,009), leucocitos (S 17.400; E 23.800; p = 0,023), urea (S 58; E 102; p < 0,001), creatinina (S 1,1; E 1,9; p = 0,032), potasio (S 3,7; E 4,4; p = 0,012) y fosfatasa alcalina (S 92; E 133; p = 0,014). Escalas predictivas: índice de Charlson (S 1; E 4; p = 0,013), criterios de sepsis grave (S 16 [36%]; E 13 [86%]; p = 0,001), Fournier's gangrene severity index score (FGSIS) (S 4; E 7; p = 0,002) y Uludag Fournier's Gangrene Severity Index (UFGSI) (S 9; E 13; p = 0,004). Los factores predictores independientes fueron la vasculopatía periférica, el potasio sérico y criterios de sepsis grave, creando un modelo con área bajo la curva de 0,850 (0,760-0,973) superior al FGSIS (0,746 [0,601-0,981]) y al UFGSI (0,760 [0,617-0,904]). CONCLUSIONES: La GF presentó una tasa de mortalidad elevada cuyos factores predictores independientes fueron la vasculopatía periférica, el potasio sérico y criterios de sepsis grave, creando un modelo con una capacidad discriminativa superior al resto

AIMS: Fournier's gangrene (FG) is the necrotizing fasciitis of the perineum and genital area and presents a high mortality rate. The aim was to assess prognostic factors for mortality, create a new mortality predictive scale and compare it with previously published scales in patients diagnosed with FG in our Emergency Department. METHODS: Retrospective analysis study between 1998 and 2012. RESULTS: Of the 59 patients, 44 survived (74%) (S) and 15 died (26%) (D). Significant differences were found in peripheral vasculopathy (S 5 [11%]; D 6 [40%]; P = .023), hemoglobin (S 13; D 11; P = .014), hematocrit (S 37; D 31.4; P = .009), white blood cells (S 17,400; D 23,800; P = .023), serum urea (S 58; D 102; P < .001), creatinine (S 1.1; D 1.9; P = .032), potassium (S 3.7; D 4.4; P = .012) and alkaline phosphatase (S 92; D 133; P = .014). Predictive scores: Charlson index (S 1; D 4; P = .013), severe sepsis criteria (S 16 [36%]; D 13 [86%]; P = .001), Fournier's gangrene severity index score (FGSIS) (S 4; D 7; P = .002) and Uludag Fournier's Gangrene Severity Index (UFGSI) (S 9; D 13; P = .004). Independent predictive factors were peripheral vasculopathy, serum potassium and severe sepsis criteria, and a model was created with an area under the ROC curve of 0.850 (0.760-0.973), higher than FGSIS (0.746 [0.601-0.981]) and UFGSI (0.760 [0.617-0.904]). CONCLUSIONS: FG showed a high mortality rate. Independent predictive factors were peripheral vasculopathy, potassium and severe sepsis criteria creating a predictive model that performed better than those previously described

Alpha-Fetoprotein-Producing Extrahepatic Tumor: Clinical and Histopathological Significance of a Case.

INTRODUCTION: The serum rise of alpha-fetoprotein (AFP) has been relationed to hepatic tumors. Other than these, such as gastric adenocarcinoma, can present with high levels of this glycoprotein. One rare kind of gastric adenocarcinoma, called hepatoid subtype, has two essential features: hepatoid differentiation in histology and high levels of AFP in serum. DISCUSSIONS: We report a Spanish female who consulted because of fatigue, anorexia, and weight loss. In laboratory data, she presented anemia and markedly elevation of AFP. On CT scan, a gastric mass resulted without hepatic dissemination, and subsequently, gastroduodenoscopy was performed for histological diagnosis. Then, an ulcerated mass was detected and sample was taken, resulting in poorly-differentiated adenocarcinoma of stomach with hepatoid tissue foci, with intense positivity for AFP-immunohistochemical staining. This rare cancer has poor prognosis even with early gastrectomy and chemotherapy.

Demanda de atención hospitalaria por gripe A/H1N1: evaluación de los primeros 1.000 casos atendidos / Hospital care of patients with A/H1N1 influenza: Evaluation of the first 1000 reported cases in Spain

Introducción y objetivos: A pesar del enorme impacto que se prevé tenga la pandemia por gripe A/H1N1 en países del hemisferio norte, todavía son escasos los datos disponibles de su repercusión a nivel hospitalario. El objetivo de este trabajo es evaluar la asistencia prestada a los pacientes atendidos por posible gripe A y su evolución en un hospital de tercer nivel.Material y método: Desde la aparición de los primeros casos se estableció un circuito específico de atención a pacientes con posible gripe A en la unidad de admisión, urgencias y hospitalización. Se diseñó un registro nominal con variables epidemiológicas y variables clínicas.Resultados: A 31 de agosto de 2009 se habían evaluado 1.018 pacientes por posible gripe A, de los que el 77% cumplía criterios clínicos. Entre los pacientes con sospecha de gripe A, la edad media (desviación estándar) fue de 31,71 (17,2) años, el 52% eran mujeres, un 3,3% de ellas embarazadas o puérperas. Ingresó el 23,4%, y la estancia media global fue de 3,5 días y de 2,5 días para los adultos que ingresaron en la unidad de corta estancia. Un 2,8% presentó neumonía y 2 pacientes necesitaron atención en unidad de cuidados intensivos (uno de ellos falleció).Conclusiones: Nuestra serie muestra una epidemia de gripe que se comporta de forma benigna con un porcentaje considerable de neumonías, pero que evolucionan favorablemente. A pesar del alto porcentaje de ingresos, y para evitar el menoscabo de la atención a otros enfermos, consideramos que un modelo asistencial basado en unidades específicas, estancias cortas y seguimiento posthospitalario puede ser adecuado (AU)

Introduction and objectives: Influenza A is expected to have a great impact in countries in the northern hemisphere yet little has been reported about how this outbreak can affect hospital care. The aim of this study is to assess patients who demand care for flu symptoms and their outcome. Material and methods: From the beginning of the outbreak a specific protocol was established for the care of patients with potential influenza A in admission, emergency and hospitalization ward. A nominal registry was designed with clinical and epidemiological data.Results: 1018 patients were evaluated for potential influenza A from the beginning of the outbreak until the 31st August, 2009. 77% of them fulfilled clinical criteria and were classified as suspected cases. Mean age was 31,7 years (SD17,2), 52% were women, 3,3% pregnant or puerperal. The admission rate was 23,4% with a global mean stay of 3,5 days, and 2,5 for the adults who were admitted to the short stay hospital unit. 2,8 % had pneumonia, two patients required admission to the intensive care unit and one of them died.Conclusions: Our data show an outbreak with mild illness, with a remarkable percentage of pneumonia but with good outcome. Despite of the high percentage of admissions, and in order to avoid the misleading attention to other patients, we believe that an assistance model based in specific units, short stay and post-discharge follow up could be suitable (AU)

Implementation of a bundle of actions to improve adherence to the Surviving Sepsis Campaign guidelines at the ED.

PURPOSES: We had previously demonstrated surviving sepsis campaign guidelines had not had enough impact at our Emergency Department. BASIC PROCEDURES: Actions directed to increase the qualification of our staff and residents, to facilitate guidelines divulgation and to improve spatial conditions by creating a High Dependency Unit were implemented as a bundle. The impact of these actions on the achievement of early objectives of the campaign and on mortality was analyzed. MAIN FINDINGS: Following campaign guidelines was more frequent after the implementation of these actions, as shown by less restrictive fluids administration for more severe cases (P = .001), earlier administration of antibiotics (P = .001) and lactate determination rate (46% vs. 12%). In-hospital mortality difference did not reach statistical difference. Physicians were able to identify high-risk patients on clinical grounds. PRINCIPAL CONCLUSIONS: The bundle of actions has had a moderate beneficial effect on our Emergency Department. High Dependency Units are useful for managing patients not fulfilling criteria for Intensive Care Unit admission.

Patient outcomes after noninvasive mechanical ventilation at a high dependency unit of an emergency department.

OBJECTIVE: To describe the outcome of patients after noninvasive ventilation in a high dependency unit (HDU) of an emergency department (ED). Secondary aims were to define the role of intensive care consultation and to identify variables associated with mortality. METHODS: Observational, prospective 6-month study. RESULTS: Two hundred and nine cases were analysed. Thirty-four patients were initially rejected by the intensive care unit (ICU). Physicians in the ED did not request ICU consultation in the remaining 175 (83%) because of 'belief of improvable medical condition in the ED in patients without therapeutic limits' in 93 (group 1) and to 'preset therapeutic limits' or 'comfort measures only' in 82 (groups 2 and 3). Ten out of these 175 were subsequently admitted to the ICU. The global in-hospital mortality rate was 22% (3.3% in the high dependency unit), but only 10% in group 1. Place of referral for ventilation (P<0.001), absence of subsequent ventilation on the general ward (P<0.001), group of assignation (P=0.004), intensive care initial rejection (P=0.022), no previous home ventilation (P=0.028), older age (P=0.03) and longer duration on ventilation (P=0.047) were significantly associated with mortality. In the multivariate regression model, ventilating patients from general wards (odds ratio=7.1; 2.3-25, 95% confidence interval) and ventilation under preset limits (odds ratio=3.57; 1.42-8.98, 95% confidence interval) remained significantly associated with mortality. CONCLUSION: Noninvasive ventilation is a relatively safe and effective treatment in the ED when performed in carefully controlled settings. ICU consultation may be securely deferred in this setting.

Failure to implement evidence-based clinical guidelines for sepsis at the ED.

OBJECTIVE: The main objective was to evaluate if consensus "bundle" measures to optimize the treatment of sepsis have been integrated in our routine practice. We also tried to identify variables significantly associated to mortality. METHODS: An observational, unblinded study of those patients who, according to their physicians, met criteria for sepsis under its different stages of severity was conducted. Six items as proposed by surviving sepsis campaign were evaluated: (1) measurement of blood lactate; (2) obtaining blood samples for culture before use of antibiotics; (3) early use of antibiotics (>3 h); (4) fluid replacement with at least 20 mL/kg of crystalloids in the first hour, unless contraindicated, if hypotension or blood lactate >4 mmol/L; (5) use of vasoactive drugs, other than dopaminergic doses of dopamine, if hypotension or shock; (6) measurement of central venous pressure and central venous O2 saturation in shock. Data concerning several aspects of diagnosis, treatment, and consultation to ICU were collected. RESULTS: Compliance with published guidelines is poor after evaluating the 6 items proposed: 12.5% of shocked patients had determinations of blood lactate; 15% of septic patients had no blood cultures drawn; 32% had received their first dose of antibiotics in the first 3 hours after admission; 46.6% of the cases of severe sepsis or shock received a fluid aggressive therapy; 43.3% of the patients with an indication for vasoactive drugs received them; no patient had central venous pressure monitoring at the ED. In addition, intensive care specialists were seldom consulted (17%). Having used dopaminergic doses of dopamine and having a respiratory focus as a source of infection were independently associated to mortality, respective OR: 21 ([1.7-254.9]; 95% CI) and 9.6 ([1.7-52]; 95% CI). CONCLUSIONS: The "bundle" measures proposed in the surviving sepsis campaign seem not to have had enough impact in our ED. This is the start point of a "plan-do-study-act" process directed to improve the outcome of patients with sepsis at our institution.
