Acute symptomatic seizures and epilepsy after mechanical thrombectomy. A prospective long-term follow-up study.

INTRODUCTION: New treatments for acute ischaemic stroke, such as mechanical thrombectomy, can achieve reperfusion of large ischaemic tissue. Some studies have suggested that reperfusion therapies can increase the risk of suffering acute symptomatic seizure (ASS) and poststroke epilepsy (PSE). The aim of the study was to determine the incidence of ASS and PSE in patients undergoing thrombectomy, and related factors. PATIENTS AND METHODS: This was a retrospective single-centre study including patients with ischaemic stroke and NIHSS> 8 treated with thrombectomy with a follow-up ≥5 years. We evaluated several epidemiological, radiological, clinical and electroencephalographic variables. RESULTS: Of the 344 included patients, 21 (6.1%) presented ASS, 53 (15.40%) died in the acute phase, and 13 (4.46%) died during the first year. The degree of reperfusion (p 0.029), advanced age (p 0.035), and haemorrhagic transformation (p 0.038) increased the risk of suffering ASS, with degree of reperfusion being an independent factor, OR 2.02 (1.21-4.64). The incidence of PSE was 4.12% in the first year, 3.72% in the second, and 1.61% in the fifth. The accumulated incidence at 5 years was 8.93%. Related risk factor for suffering PSE was ASS (p < 0.001), yielding an OR value of 2.00 (1.28-3.145). CONCLUSIONS: Thrombectomy doesn´t increase the risk of ASS. A higher percentage of reperfusion, advanced age, and haemorrhagic transformation are associated with an increased risk of ASS. ASS is a risk factor for suffering PSE. In terms of mortality, having suffered ASS and/or PSE does not increase acute or long-term mortality.

Hypersensitivity Reactions to Cancer Chemotherapy: Practical Recommendations of ARADyAL for Diagnosis and Desensitization.

Rapid drug desensitization has enabled first-line therapies in patients with drug hypersensitivity reactions to chemotherapeutic drugs including monoclonal antibodies. Desensitization is a safe and highly effective procedure, not only for IgE-mediated reactions, but also for those mediated by non-IgE mechanisms. The likelihood of breakthrough reactions during desensitization is low, and most are mild; in fact, moderate-to-severe reactions are infrequent. In this document, 16 allergy departments belonging to the Spanish research network ARADyAL present a review of the available scientific evidence and provide general guidelines for the diagnosis and management of drug hypersensitivity reactions to chemotherapeutic drugs and monoclonal antibodies. Emphasis is placed on the desensitization procedure.

Spanish Society of Allergology and Clinical Immunology (SEAIC) Vision of Drug Provocation Tests.

The controlled drug provocation test (DPT) is currently considered the gold standard for the diagnosis of drug allergy. Adverse drug reactions (ADRs) are an increasingly common presenting complaint in both primary and specialized care. In Spain, ADRs are usually assessed via the allergology department, which rules out immunological mechanisms in up to 90% of cases. An adequate approach to ADRs clearly impacts the costs and efficacy of the treatments prescribed by other specialists. Consequently, if we did not use DPTs, patients would require more expensive, more toxic, and less effective treatments in many cases. In recent years, many new drugs have been developed. This document is intended to be a practical guideline for the management of DPTs according to the vision of the Spanish Allergology Society. The diagnostic work-up begins with a detailed clinical history. Skin tests are only useful for some medications, and in most cases the diagnosis can only be confirmed by DPT. Although cross-reactivity is common, DPTs can confirm the diagnosis and help to find an alternative drug. Programmed individualized patient management based on the type of drug to be studied and the patient´s comorbidities usually enables a solution to be found in most cases.

Diagnostic agreement between video capsule endoscopy and single and double balloon enteroscopy for small bowel bleeding at a tertiary care hospital in Bogota, Colombia. / Concordancia diagnóstica entre la videocápsula endoscópica y enteroscopia mono y de doble balón en la hemorragia de intestino delgado en un hospital de alta complejidad en Bogotá, Colombia.

INTRODUCTION: Video capsule endoscopy and balloon-assisted enteroscopy are complementary diagnostic methods in the study of small bowel bleeding, and different factors can affect their diagnostic yield. AIMS: To define the level of agreement between video capsule endoscopy and enteroscopy in small bowel bleeding, according to the type of lesion, in a cohort of patients at a tertiary care referral center. MATERIALS AND METHODS: A retrospective study was conducted that included 428 capsule endoscopies performed within the time frame of 2011 and 2019 at our healthcare institution. Seventy-four video capsule endoscopies, followed by enteroscopy, in 71 patients suspected of presenting with small bowel bleeding, were analyzed. RESULTS: Mean patient age was 63.9 ± 13.5 years and 42 patients were women. The two diagnostic procedures were performed. Overall diagnostic yield of positive findings between video capsule endoscopy and enteroscopy was 86.5% vs. 58.1%, respectively (p = 0.0527). Agreement between video capsule endoscopy and enteroscopy for positive pathologic findings was weak (Ik = 0.17, 95% CI: -0.0097-0.3543), but according to lesion type, it was good for inflammatory lesions (Ik = 0.71, 95% CI: 0.5182-0.9119) and moderate for angiectasias (Ik = 0.45, 95% CI: 0.2469-0.6538) and tumors (Ik = 0.40, 95% CI: 0.1217-0.6794). The results between the two methods differed in 38 patients (51.3%). There was complete intestinal capsule retention in one patient (1.4%) and active bleeding in 13 (17.6%). CONCLUSIONS: The present study showed that the two techniques had a similar overall detection rate for small bowel lesions, but the type of lesion was the main factor that could modify diagnostic agreement.

La desensibilización a medicamentos ha permitido la administración de fármacos de primera línea en pacientes con reacciones dehipersensibilidad (RH) a quimioterápicos (QT), incluyendo los anticuerpos monoclonales (AcM). La desensibilización es un procedimientoseguro y altamente efectivo, no únicamente para las reacciones mediadas por IgE sino también para aquellas relacionadas con un mecanismoindependiente de IgE. El riesgo de reacciones durante la desensibilización es bajo y frecuentemente las reacciones observadas son leves,considerándose infrecuentes las reacciones moderadas o graves.En este documento, dieciséis Servicios de Alergia pertenecientes a la red española de investigación ARADyAL presentan una revisiónde la evidencia científica disponible y sugieren unas pautas de actuación generales para el diagnóstico y manejo de las RH a QT y AcM,centrándose en el proceso de desensibilización (AU)

La prueba de exposición controlada a fármacos (DPT) se considera actualmente el estándar de oro para el diagnóstico de alergia amedicamentos. Las reacciones adversas inducidas por medicamentos (RAM) son un motivo creciente de consulta tanto en atención primariacomo especializada. Las consultas de Alergología en España son las que habitualmente estudian estas RAM y descartan mecanismosinmunológicos implicados hasta en el 90% de los casos consultados. Un abordaje adecuado de estos casos repercute de una maneraevidente en los costes y la eficacia de los tratamientos requeridos por otros especialistas, de modo que, si no empleáramos los DPT, lospacientes requerirían tratamientos más costosos, más tóxicos y menos eficaces en la mayoría de los casos.En los últimos años se han desarrollado un gran número de nuevos fármacos y este documento pretende ser una guía práctica en lagestión de las DPT con la visión de la Sociedad Española de Alergología. El trabajo de diagnóstico comienza con un historial detalladodel paciente. Las pruebas cutáneas solo son útiles en algunos medicamentos y, en la mayoría de los casos, el diagnóstico solo puedeconfirmarse mediante el DPT. Aunque suele haber reactividad cruzada, las DPT pueden confirmar el diagnóstico y también contribuir aencontrar un fármaco alternativo tolerable. El manejo individual de los pacientes de forma programada, teniendo en cuenta tanto eltipo de fármaco a estudiar como las comorbilidades del paciente, suele permitir encontrar una solución para la mayoría de los pacientes (AU)

A fatal gastric perforation secondary to ulcerated metastasis in undiagnosed breast cancer: pathological aspects and review of literature.

The authors describe a fatal case of gastric perforation secondary to an ulcerated metastasis in a woman with undiagnosed breast cancer. The 48-year-old woman, with no significant medical history, presented with weight loss, persistent dyspepsia and pain in the epigastric and mesogastric region. She was treated by her primary care physician with proton-pump inhibitors and antispasmodics. The following day she was found dead at her home. External examination showed a tumefaction in the lateral region of her left breast, near the axilla. Autopsy revealed 1000 ml of turbid, light-brown peritoneal fluid in the abdominal cavity and a perforated gastric wall. Histological examination of the breast mass showed an infiltrating, poorly-differentiated breast carcinoma. Microscopical analysis of the stomach wall revealed a perforated metastatic gastric ulcer. Immunohistochemistry was required to confirm the neoplastic involvement of the stomach due to metastatic breast cancer.

Incidence, recurrence and cost of hyperglycaemic crises requiring emergency treatment in Andalusia, Spain.

AIMS: Hyperglycaemic crises (diabetic ketoacidosis and hyperosmolar hyperglycaemic state) are medical emergencies in people with diabetes. We aimed to determine their incidence, recurrence and economic impact. METHODS: An observational study of hyperglycaemic crises cases using the database maintained by the out-of-hospital emergency service, the Healthcare Emergency Public Service (EPES) during 2012. The EPES provides emergency medical services to the total population of Andalusia, Spain (8.5 million inhabitants) and records data on the incidence, resource utilization and cost of out-of-hospital medical care. Direct costs were estimated using public prices for health services updated to 2012. RESULTS: Among 1 137 738 emergency calls requesting medical assistance, 3157 were diagnosed with hyperglycaemic crises by an emergency coordinator, representing 2.9 cases per 1000 persons with diabetes [95% confidence intervals (CI) 2.8 to 3.0]. The incidence of diabetic ketoacidosis was 2.5 cases per 1000 persons with diabetes (95% CI 2.4 to 2.6) and the incidence of hyperosmolar hyperglycaemic state was 0.4 cases per 1000 persons with diabetes (95% CI 0.4 to 0.5). In total, 17.7% (n = 440) of people had one or more hyperglycaemic crisis. The estimated total direct cost was €4 662 151, with a mean direct cost per episode of €1476.8 ± 217.8. CONCLUSIONS: Hyperglycaemic crises require high resource utilization of emergency medical services and have a significant economic impact on the health system.

Incidence and care-related costs of severe hypoglycaemia requiring emergency treatment in Andalusia (Spain): the PAUEPAD project.

AIMS: Hypoglycaemia is a serious medical emergency. The need for emergency medical service care and the costs of hypoglycaemic emergencies are not completely known. METHODS: This was a retrospective observational study using Public Company for Health Emergencies (EPES) data for hypoglycaemia in 2012. The EPES provides emergency medical services to the entire population of Andalusia, Spain (8.5 million people). Data on event type, onsite treatments, emergency room visits or hospitalization were collected. Medical costs were estimated using the public rates for healthcare services. RESULTS: From a total of 1 137 738 emergency calls that requested medical assistance, 8683 had a primary diagnosis of hypoglycaemia (10.34 per 10 000 person-years). The incidence of severe hypoglycaemic episodes requiring emergency treatment in the estimated population with diabetes was 80 episodes per 10 000 person-years. A total of 7479 episodes (86%) required an emergency team to visit the patient's residence. The majority of cases (64%) were addressed in the residence, although 1784 (21%) cases were transferred to hospital. A total of 5564 events (65%) involved patients aged > 65 years. Overall mortality was 0.32% (28 cases). The total annual cost of attending a hypoglycaemic episode was €6 093 507, leading to an estimated mean direct cost per episode of €702 ± 565. Episodes that required hospital treatment accounted for 49% of the total costs. CONCLUSIONS: Hypoglycaemia is a common medical emergency that is associated with high emergency medical service utilization, resulting in a significant economic impact on the health system.
