Histopathological and virological features of lung, heart and liver percutaneous tissue core biopsy in patients with COVID-19: A clinicopathological case series.

INTRODUCTION: Data on pathological changes in COVID-19 are scarce. The aim of this study was to describe the histopathological and virological findings of postmortem biopsies, and the existing clinical correlations, in people who died of COVID-19. MATERIALS AND METHODS: We performed postmortem needle core biopsies of the chest in 11 people who died of COVID-19 pneumonia. Tissue examination was done by light microscopy and real-time polymerase chain reaction (RTPCR). RESULTS: The age of the patients were between 61 to 94 years. Of the 11 postmortem chest biopsies, lung tissue was obtained in 8, myocardium tissue in 7, and liver tissue in 5. Histologically of lung, the main findings pertaining to the lung were diffuse alveolar damage in proliferative phase (n = 4, 50%), diffuse alveolar damage in exudative and proliferative phase (n = 3, 37.5%), diffuse alveolar damage in exudative (n=1; 12.5%) and acute pneumonia (n = 2, 25%). Necrotising pneumonia, acute fibrinous and organising pneumonia, and neutrophils were detected in one sample each (12.5%). Another case presented myocarditis. RT-PCR showed RNA of SARS-CoV-2 in 7 of the 8 lung samples (87.5%), 2 of the 7 myocardial tissue samples (28.6%), and 1 of the 5 liver tissue samples (20%). CONCLUSION: The postmortem examinations show diffuse alveolar damage, as well as acute or necrotising pneumonia. RT-PCR of SARS-CoV-2 was positive in most lung samples.

Analysis of adherence to HIV-positive quality of care indicators and their impact on service quality perceptions in patients: a Spanish cross-sectional study.

BACKGROUND: Since the identification of human immunodeficiency virus (HIV) infection, there have been significant advances in its diagnosis and treatment, but there have been few contributions to the area of care quality. In 2010, the Spanish AIDS Study Group (GeSIDA) published the document "Health quality indicators of GeSIDA for the care of people infected with HIV/AIDS" in which standards are proposed for the purpose of improving and standardizing the assistance provided to people infected with HIV. The purpose of this study was to evaluate the degree of compliance with these indicators and to analyse whether adherence to the standards improves patient perception of care quality in terms of their satisfaction with the health care they have received. METHODS: Compliance with GeSIDA indicators was analysed within a cohort of people living with HIV (PLHIV) in a hospital in the Madrid region. To evaluate patient perception, the External Consultation User Satisfaction Questionnaire (SUCE) was used, which is a tool that was previously validated in the Spanish population. RESULTS: A total of 334 patients were included. The level of adherence to the indicators was 74.46%. The score on the SUCE questionnaire was 9.04 out of 10 (CI 95%: 8.90-9.19). Of the 47 indicators assessed, only 4 were related to satisfaction with health care. CONCLUSIONS: The levels of compliance with the indicators and patient satisfaction with health care were high. Adherence to quality indicators showed little relation to patient-reported satisfaction.

Evaluation of direct oral anticoagulants for the treatment of cancer-associated thrombosis: an update.

Cancer is associated with an increased risk of venous thromboembolism of four to sixfold. Cancer-related interventions such as chemotherapy, hormonal therapy and indwelling central venous catheters also increase the risk of venous thromboembolism. Low molecular weight heparin for at least 3-6 months is the current standard of care for the treatment of cancer associated venous thromboembolism. Anticoagulation should be continued as long as the cancer is active. Over the past few years, direct oral anticoagulants have emerged, including one direct thrombin inhibitor (dabigatran etexilate) and three factor Xa inhibitors (apixaban, edoxaban and rivaroxaban). In the randomized controlled trials comparing direct oral anticoagulants with vitamin K antagonists, the direct oral anticoagulants all provide non-inferior in prevention of thromboembolic events in patients with atrial fibrillation, for the prevention and treatment of venous thromboembolism and in acute coronary syndrome. In people with cancer, these drugs have emerged as attractive alternatives for the treatment of venous thromboembolism with the potential to overcome the limitations of low molecular weight heparin. Randomized controlled studies comparing direct oral anticoagulants to low molecular weight heparin in cancer patients are still limited and direct oral anticoagulants are not recommended for the treatment of cancer associated venous thromboembolism yet. However, new emerging data are supporting the use of direct oral anticoagulants in cancer-associated thrombosis. Here, we review recent data on the evidence related to the efficacy and safety of direct oral anticoagulants for the treatment of venous thromboembolism in patients with cancer.

Interleukin (IL) -1 ß, IL-6 and tumor necrosis factor in patients with seasonal flu.

OBJECTIVE: The role of tumor necrosis factor (TNF), interleukin (IL)-1ß and IL-6 in the pathogenicity of seasonal flu is unknown. METHODS: We analyzed the profiles of these cytokines in 77 flu patients and 17 controls with non-flu respiratory infection, using molecular biology techniques (real-time polymerase chain reaction). RESULTS: Flu patients had lower monocyte counts (p=0.029) and a slightly lower median level of IL-6 (P=0.05) than the control group. Twenty-four flu patients (31.2%) had pneumonia; this group had higher C-reactive proteins (p=0.01) and monocyte levels (p=0.009). Pro-inflammatory cytokines levels did not rise in patients with pneumonia complicating seasonal influenza. CONCLUSIONS: IL-6 levels were lower in adults with influenza.

Síndrome de POEMS incompleto asociado a enfermedad de Castleman multicéntrica y amiloidosis / Incomplete POEMS syndrome with multicentric Castleman’s disease and amyloidosis

La enfermedad de Castleman (EC) es un trastorno linfoproliferativo atípico de causa desconocida, caracterizado por crecimiento ganglionar hiperplásico no clonal. Actualmente se reconocen dos formas de presentación clínica, una localizada y otra multicéntrica, y cuatro variantes histopatológicas. Clínicamente se caracteriza por linfadenopatías generalizadas, hepatoesplenomegalia, fiebre y sudoración nocturnas. La EC puede presentar pancitopenia grave y fallo multiorgánico, evolucionar a linfoma y, en algunas ocasiones, asociarse a síndromes paraneoplásicos como el síndrome de POEMS. Las asociaciones de estas dos entidades han sido ampliamente descritas en la literatura actual, aunque su asociación con amiloidosis es menos frecuente y descrita como casos clínicos aislados. Presentamos un caso clínico con esta triple asociación: EC, POEMS y amiloidosis (AU)

Castleman’s disease (CD) is an atypical lymphoproliferative disorder of unknown cause, characterized by non-clonal nodal hyperplastic growth. Two forms of clinical presentation are currently recognized, one localized and the other multicentric, and four histopathologic variants. It is characterized by generalized lymphadenopathy, hepatosplenomegaly, fever and night sweats. CD may present severe pancytopenia, multi-organ failure, lymphoma evolution and it can sometimes be associated with paraneoplastic syndromes such as POEMS syndrome. Associations of these two entities have been widely described in the current literature, although its less common association with amyloidosis is described as isolated clinical cases. We report a case with this triple association: EC, POEMS and amyloidosis (AU)

Seasonal influenza in octogenarians and nonagenarians admitted to a general hospital: epidemiology, clinical presentation and prognostic factors / Gripe estacional en octogenarios y nonagenarios ingresados en un hospital general: epidemiología, clínica y factores pronósticos

Background. Seasonal influenza is responsible for high annual morbidity and mortality worldwide, especially in elderly patients. The aim of the study was to analyse the epidemiological, clinical and prognostic features of influenza in octogenarians and nonagenarians admitted to a general hospital, as well as risk factors associated with mortality. Methods. Retrospective, cross-sectional, descriptive study in patients admitted and diagnosed with influenza by molecular biology in the General University Hospital of Alicante from 1 January to 31 April 2015. Results. A total of 219 patients were diagnosed with influenza in the study period: 55 (25.1%) were ≤64 years-old; 77 (35.2%) were aged 65-79; 67 (30.6%) were aged 80-89 years; and 20 (9.1%) were aged ≥90 years. Most flu episodes were caused by influenza A (n=181, 82.6%). Patients aged 80 years or older had lower glomerular filtration rate (mean: 49.7 mL/min vs. 62.2 mL/min; p=0.006), a greater need for non-invasive mechanical ventilation (22% vs 9.3%; p=0.02), greater co-morbidity due to cardiac insufficiency (40.5% vs. 16.4%; p<0.001) and chronic renal disease (32.9 vs. 20%, p=0.03), and greater mortality (19% vs. 2.9%; p<0.001). In a multivariate analysis, mortality was higher in those aged 80 or over (adjusted odds ratio [ORa] 9.2, 95% confidence interval [CI] 1.65-51.1), those who had acquired the flu in a longterm care facility (ORa 11.9, 95% CI 1.06-134), and those with hyperlactataemia (ORa 1.89, 95% CI 1.20-3.00). Conclusions. Seasonal influenza is a serious problem leading to elevated mortality in octogenarian and nonagenarian patients admitted to a general hospital (AU)

Recurrence risk of idiopathic venous thromboembolism. / Riesgo de recurrencia en el tromboembolismo venoso idiopático.

For patients with idiopathic venous thromboembolism (unprovoked), the risk of recurrence is high. Secondary prophylaxis with anticoagulant therapy reduces the thrombotic risk but at the expense of an increased risk of haemorrhage. A number of factors, such as the male sex and an increase in dimer-D concentrations after completing the anticoagulation therapy, are associated with an increased risk of recurrence. Other factors such as residual venous thrombosis have a more controversial and sometimes contradictory relationship. A number of models have been proposed for predicting thrombotic recurrence risk after anticoagulation therapy in unprovoked TVD. However, these models need external validation to determine their current usefulness in clinical practice. In this article, we analyse the risk factors for thrombotic recurrence and the existing prediction models.

A risk score for prediction of recurrence in patients with unprovoked venous thromboembolism (DAMOVES).

BACKGROUND: In patients with unprovoked venous thromboembolism (VTE), the optimal duration of anticoagulation is anchored on estimating the risk of disease recurrence. We aimed to develop a simple risk assessment model that improves prediction of the recurrence risk. METHODS: In a prospective cohort study, 398 patients with a first unprovoked VTE were followed up for a median of 21.3months after discontinuation of anticoagulation. We excluded patients with a strong thrombophilic defect. Preselected clinical and laboratory variables were analyzed based on the independent confirmation of the impact on the recurrence risk, simplicity of assessment, and reproducibility. Multivariable Cox regression analysis was used to develop a recurrence score that was subsequently internally validated by bootstrap analysis. RESULTS: A total of 65 patients (16.3%) had recurrent VTE. In all patients, VTE recurred spontaneously. Male sex (HR=2.89 [95% CI 1.21-6.90] P=0.016), age (HR=1.0310 per additional decade [95% CI 1.01-1.07] P=0.011), obesity (HR=3.92 [95% CI 1.75-8.75] P=0.0001), varicose veins (HR=4.14 [95% CI 1.81-9.43] P=0.0001), abnormal D-dimer during anticoagulation (HR=13.66 [95% CI 4.74-39.37] P=0.0001), high factor VIII coagulant activity (HR=1.01 [95% CI 1.00-1.02] P=0.028) and heterozygous of factor V Leiden and/or Prothrombin G20210A mutation (HR=13.86 [95% CI 5.87-32.75] P=0.0001) were related to a higher recurrence risk. Using these variables, we developed a nomogram [hereafter referred to as DAMOVES score (D-dimer, Age, Mutation, Obesity, Varicose veins, Eight, Sex)] for prediction of recurrence in an individual patient. CONCLUSIONS: The DAMOVES score can be used to predict recurrence risk in patients with a first unprovoked VTE and may be useful to decide whether anticoagulant therapy should be continued indefinitely or stopped after an initial treatment period of at least 3months.

Corpora amylacea in the neocortex in patients with temporal lobe epilepsy and focal cortical dysplasia.

INTRODUCTION: Corpora amylacea (CoA) are present in about 60% of atrophic hippocampi resected from patients with drug resistant temporal lobe epilepsy (DRTLE). They have also been described in the lateral temporal neocortex, although less frequently. OBJECTIVE: The objective is to measure the presence, distribution and density of CoA in the lateral temporal lobes of patients with DRTLE and focal cortical dysplasia (FCD), also examining how CoA density may be linked to demographic and clinical traits. METHODS: Resected tissue from 35 patients was analysed. CoA density was assessed with a semi-quantitative scale according to the criteria established by Cherian et al. RESULTS: Presence of CoA in the neocortex of 9 patients was associated with hippocampal sclerosis (FCD type iiia, 7 cases), disembryoplastic neuroepithelial tumour (FCD type iiib, 1 case), and cavernous angioma (FCD type iiic, 1 case). The meningeal surface (MS) was involved in all cases, and 8 cases displayed CoA in the cerebral parenchyma (white matter) and around blood vessels. CoA density on the MS showed a negative correlation with age at seizure onset (r = -0.828, P<.05) and a positive correlation with disease duration (r = 0.678, P<.05) but not with postoperative clinical outcome. CONCLUSIONS: Patients with DRTLE and a primary lesion (hippocampal sclerosis, tumour, vascular malformation) associated with mild FCD were shown to have CoA deposits in the neocortex. No association was found between presence of CoA and clinical outcome one year after surgery.

Accuracy of systolic aortic regurgitation in the diagnosis of heart failure: a predictive approach.

BACKGROUND: Systolic aortic regurgitation (SAR) is a curious phenomenon that has been found to be associated with heart failure (HF). We aimed to determine de diagnostic value of SAR as a black box predictive tool in patients with suspected HF admitted to hospital with dyspnea as leading symptom. METHODS AND RESULTS: Cross-sectional study including 269 consecutive patients admitted to hospital with dyspnea as leading symptom without definite clinical diagnosis. SAR was defined by echocardiography as the presence of blood flow from the aorta to the left ventricular outflow tract during a complete systole. The reference standard was the presence of HF diagnosis at discharge. SAR was present in 9 (3.3%) patients. Prevalence of HF was 40.3%. Specificity of SAR in the diagnosis of HF was high at 99.4% (95% CI 96.5-99.9%). Sensitivity was 7.5% (95% CI 3.9-14.2%). Positive predictive value (PPV) was 88.9% (95% CI 56.5-98.0%). Positive likelihood ratio was 11.85. Estimated PPV of SAR was significantly higher than 50% for any hypothetical prevalence of HF. CONCLUSION: In patients admitted to hospital with dyspnea, the finding of systolic aortic regurgitation in echocardiography has a high PPV for HF diagnosis at discharge.

Manifestaciones neurológicas de los mixomas cardiacos. Experiencia en un centro de referencia / Neurological manifestations of cardiac myxoma: Experience in a referral hospital

Introducción: El mixoma cardiaco es una causa poco frecuente pero importante de infarto cerebral en pacientes jóvenes. Existen pocas series de pacientes que analicen la frecuencia de las manifestaciones neurológicas en pacientes con mixoma y su presentación clínica. Objetivo: Conocer las complicaciones neurológicas del mixoma cardiaco en nuestro hospital durante los últimos 28 años. Pacientes y métodos: Revisión retrospectiva de las manifestaciones neurológicas de 36 pacientes operados de mixoma cardiaco con confirmación patológica en nuestro centro desde diciembre de 1983 hasta marzo del 2012. Resultados: Ocho de los 36 pacientes con mixomas cardiacos (22%) intervenidos en nuestro centro presentaron clínica neurológica. El 50% eran mujeres y la edad media ± desviación estándar de 52,4 ± 11,6 años. El síntoma neurológico más frecuente fue la hemiparesia de aparición brusca (63%). El ictus isquémico establecido fue la manifestación clínica más frecuente (75%), seguido del accidente isquémico transitorio. El territorio más afectado fue el de la arteria cerebral media. En todos los casos se alcanzó el diagnóstico del tumor mediante ecocardiografía. El tamaño medio del mixoma fue de 4,12 cm. La mayoría (63%) presentaba una superficie polipoide. Todos los tumores fueron resecados quirúrgicamente con éxito. No hubo muertes hospitalarias. Conclusiones: Los mixomas cardíacos comienzan frecuentemente con manifestaciones neurológicas, en particular como eventos isquémicos (AIT o ictus establecidos) en pacientes jóvenes y sin factores de riesgo cardiovascular. El territorio anterior, en especial la arteria cerebral media, suele estar más frecuentemente afectado. La ecocardiografía puede facilitar el diagnóstico y permitir un tratamiento precoz de la lesión (AU)

Introduction: Cardiac myxoma is an important but uncommon cause of stroke in younger patients. Few published case series analyse the frequency and clinical presentation of neurological complications in patients with myxoma. Objective: To list all neurological complications from cardiac myxoma recorded in our hospital in the past 28 years. Patients and methods: We retrospectively reviewed the neurological manifestations of cardiac myxoma in patients treated in our hospital between December 1983 and March 2012. Results: Of the 36 patients with cardiac myxoma, 8 (22%) presented neurological manifestations. Half were women and mean age of patients was 52.4 ± 11.6 years. Sudden-onset hemiparesis was the most frequent neurological symptom (63%). Established ischaemic stroke was the most common clinical manifestation (75%), followed by transient ischemic attack. The most commonly affected territory corresponded to the middle cerebral artery. Myxoma was diagnosed by echocardiography in all cases. Mean myxoma size was 4.1 cm and most of the tumours (63%) had a polypoid surface. All tumours were successfully removed by surgery. There were no in-hospital deaths. Conclusions: Cardiac myxomas frequently present with neurological symptoms, especially ischaemic events (established stroke or transient ischaemic attack), in younger patients with no cardiovascular risk factors. The anterior circulation is more frequently affected, especially the middle cerebral artery. Echocardiography can facilitate prompt diagnosis and early treatment of the lesion (AU)

Estudio del consumo de fármacos inadecuados o no indicados en el anciano que ingresa en un Servicio de Medicina Interna / Study of the consumption of innapropiate medicaments in elder hospitalized in the internal medicine service

Introducción: Los pacientes ancianos se caracterizan por el alto grado de polimedicación. Este factor se ha mostrado el más importante en la aparición de efectos adversos (EAF). El estudio de los fármacos ayuda a establecer cuales son inapropiados y por lo tanto se deben retirar, disminuyendo de esta forma la posibilidad de EAF. Material y Métodos: Estudio prospectivo y observacional. Criterio de inclusión: pacientes de > 64 años que ingresan en Medicina Interna. Se definió como fármaco inapropiado los medicamentos de baja utilidad terapéutica (UTB), los no indicados, y los inadecuados para el anciano. Mediante el programa informático SPSS 11.5 se analizaron las posibles variables relacionadas con el consumo. Resultados: Se incluyeron en el estudio 172 ancianos. La media de medicamentos por persona y día fue de 5,34 (0-15). El 52,5% consumían un fármaco inapropiado (36,6% inadecuado para el anciano, 15% noindicado y 12% UTBs). El análisis multivariante asocia el consumo de estos fármacos a un mayor número de patologías (p < 0,012), a un mayor consumo de medicamentos (p < 0,001) y a la procedencia de residencias de ancianos (p < 0,001). Sólo el consumo de fármacos no adecuados para el anciano se asocia a aumento de EAF. Conclusión: La mitad de los ancianos toma al menos un fármaco deforma innecesaria, y la mayoría de estos fármacos favorece la aparición de EAF

Background: The elderly patients are characterized by the high degree of polymedication. This factor is the most important in the appearance of adverse effects (EAD). The study of the medicaments helps to establish which are inappropriate and therefore they must move back, diminishing of this form EAD’s possibility. Patients and Method: Prospective and observacional Study. Criterion of incorporation: patients of > 64 years old, hospitalized in an Internal Medicine Service. There were defined as inappropriate medicament the medicines of low therapeutic utility, them not indicated, and the inadequate ones for the elder. By means of the SPSS 11.5 program the possible variables related with the consumption were analyzed. Results: 172 elders were included in the study. The average of medicines for person and day belonged to 5.34 (0-15). 52.5% was consuming an inappropriate medicament (36.6% inadequate for the elder, 15% not indicated, and 12% UTBs). The analysis multivariant associates the consumption of these medicaments with a major number of diseases (p <0.012), to a major consumption of medicines (p < 0.001) and to the origin of the nursing residences (p < 0.001). Only the consumption of medicaments not adapted for the elder is associated with increase of EAD. Conclusion: The half of the elders takes at least a medicament of unnecessary form, and the majority of these medicaments favors appearance of EAD

[Pathological neocortical findings in patients with medication-resistant medial temporal lobe epilepsy submitted to surgery]. / Hallazgos patológicos neocorticales en pacientes con epilepsia del lóbulo temporal medial farmacorresistente sometidos a cirugía.

INTRODUCTION: The dual pathology consisting of hippocampal sclerosis plus focal cortical dysplasia (FCD) is often reported in patients with medication-resistant medial temporal lobe epilepsy (MTLE). AIMS: To determine the histopathological changes that take place in the neocortex of patients with medication-resistant MTLE submitted to surgery and to evaluate the relation between the histopathological changes, pathological background and the clinical course of patients who had received surgical treatment. MATERIALS AND METHODS: Tissue obtained by en bloc resection from the neocortex of 18 patients with MTLE refractory to medical treatment was processed histologically and a tailored temporal lobectomy was performed with electrocorticography. RESULTS: Dual pathology was diagnosed in 13 patients (72.2%). Imaging studies confirmed the existence of mesial sclerosis of the temporal in 100% of cases and there was no evidence of neocortical lesions. Histologically, 46.15% and 38.46% of the patients were diagnosed as belonging to FCD type 1a and FCD type 1b, respectively. Only one patient presented FCD type 2a. A statistically significant relation was found between the presence of dual pathology and the existence of an early precipitating injury (p = 0.04). One year after surgery, 72.7% (8/11) patients with dual pathology were classified as belonging to Engel class I. CONCLUSIONS: In patients with MTLE there are microscopic FCD-type alterations in the neocortex. There is an association between these alterations and the existence of an initial precipitating injury. Complete resection of the epileptogenic area, which is guaranteed by the lobectomy tailored by electrocorticography, allows patients to enjoy a favourable post-surgical progression one year after surgery.

Histologically, 46.15% and 38.46% of the patients were diagnosed as belonging to FCD type 1a and FCD type 1b, respectively. Only one patient presented FCD type 2a. A statistically significant relation was found between the presence of dual pathology and the existenceof an early precipitating injury (p = 0.04). One year after surgery, 72.7% (8/11) patients with dual pathology were classified as belonging to Engel class I. Conclusions. In patients with MTLE there are microscopic FCD-type alterations in the neocortex.There is an association between these alterations and the existence of an initial precipitating injury. Complete resection of the epileptogenic area, which is guaranteed by the lobectomy tailored by electrocorticography, allows patients to enjoy a favourable post-surgical progression one year after surgery

[Study of the conpsumption of innapropiate medicaments in elder hospitalized in the Internal Medicine Service]. / Estudio del consumo de fármacos inadecuados o no indicados en el anciano que ingresa en un Servicio de Medicina Interna.

BACKGROUND: The elderly patients are characterized by the high degree of polymedication. This factor is the most important in the appearance of adverse effects (EAD). The study of the medicaments helps to establish which are inappropriate and therefore they must move back, diminishing of this form EAD's possibility. PATIENTS AND METHOD: Prospective and observacional Study. Criterion of incorporation: patients of > 64 years old, hospitalized in an Internal Medicine Service. There were defined as inappropriate medicament the medicines of low therapeutic utility, them not indicated, and the inadequate ones for the elder. By means of the SPSS 11.5 program the possible variables related with the consumption were analyzed. RESULTS: 172 elders were included in the study. The average of medicines for person and day belonged to 5.34 (0-15). 52.5% was consuming an inappropriate medicament (36.6% inadequate for the elder, 15% not indicated, and 12% UTBs). The analysis multivariant associates the consumption of these medicaments with a major number of diseases (p < 0.012), to a major consumption of medicines (p < 0.001) and to the origin of the nursing residences (p < 0.001). Only the consumption of medicaments not adapted for the elder is associated with increase of EAD. CONCLUSION: The half of the elders takes at least a medicament of unnecessary form, and the majority of these medicaments favors appearance of EAD.
