Clinical standards for diagnosis, treatment and prevention of post-COVID-19 lung disease.

BACKGROUND: The aim of these clinical standards is to provide guidance on 'best practice' care for the diagnosis, treatment and prevention of post-COVID-19 lung disease.METHODS: A panel of international experts representing scientific societies, associations and groups active in post-COVID-19 lung disease was identified; 45 completed a Delphi process. A 5-point Likert scale indicated level of agreement with the draft standards. The final version was approved by consensus (with 100% agreement).RESULTS: Four clinical standards were agreed for patients with a previous history of COVID-19: Standard 1, Patients with sequelae not explained by an alternative diagnosis should be evaluated for possible post-COVID-19 lung disease; Standard 2, Patients with lung function impairment, reduced exercise tolerance, reduced quality of life (QoL) or other relevant signs or ongoing symptoms ≥4 weeks after the onset of first symptoms should be evaluated for treatment and pulmonary rehabilitation (PR); Standard 3, The PR programme should be based on feasibility, effectiveness and cost-effectiveness criteria, organised according to local health services and tailored to an individual patient's needs; and Standard 4, Each patient undergoing and completing PR should be evaluated to determine its effectiveness and have access to a counselling/health education session.CONCLUSION: This is the first consensus-based set of clinical standards for the diagnosis, treatment and prevention of post-COVID-19 lung disease. Our aim is to improve patient care and QoL by guiding clinicians, programme managers and public health officers in planning and implementing a PR programme to manage post-COVID-19 lung disease.

TB in the elderly: clinical features and outcomes.

BACKGROUND: TB in low-incidence countries is characterised by changes in age distribution towards larger numbers of cases among the elderly.OBJECTIVES: To investigate clinical features and outcomes of TB treatment in older patients and identify predictors of poor outcome.METHODS: Multicentre retrospective study of new TB cases from 53 hospitals included in the registry of the Integrated Tuberculosis Research Programme of the Spanish Society of Pulmonology and Thoracic Surgery (Sociedad Española de Neumología y Cirugía Torácica) between 2006 and 2020.RESULTS: We identified 731 patients aged ≥75 years from a cohort of 7,505 patients with TB. In the elderly, weight loss, disseminated disease and normal X-rays or infiltrates without cavitation were more common. All-cause mortality was 16% (5% of deaths due to TB). The elderly had higher rates of toxicity (6.7%) and hospital admissions (36%). In the multivariate analysis of predictors of TB mortality in ≥75-year-olds, only weight, age and treatment with non-standard regimens remained significant.CONCLUSIONS: TB in older patients needs more attention and remains a challenge because of a lack of specific clinical and radiological features. Standard treatment is effective, although mortality is higher than in young patients. Low weight, non-standard regimens and age are significant predictors of TB mortality.

Clinical standards for drug-susceptible pulmonary TB.

BACKGROUND: The aim of these clinical standards is to provide guidance on 'best practice´ for diagnosis, treatment and management of drug-susceptible pulmonary TB (PTB).METHODS: A panel of 54 global experts in the field of TB care, public health, microbiology, and pharmacology were identified; 46 participated in a Delphi process. A 5-point Likert scale was used to score draft standards. The final document represents the broad consensus and was approved by all 46 participants.RESULTS: Seven clinical standards were defined: Standard 1, all patients (adult or child) who have symptoms and signs compatible with PTB should undergo investigations to reach a diagnosis; Standard 2, adequate bacteriological tests should be conducted to exclude drug-resistant TB; Standard 3, an appropriate regimen recommended by WHO and national guidelines for the treatment of PTB should be identified; Standard 4, health education and counselling should be provided for each patient starting treatment; Standard 5, treatment monitoring should be conducted to assess adherence, follow patient progress, identify and manage adverse events, and detect development of resistance; Standard 6, a recommended series of patient examinations should be performed at the end of treatment; Standard 7, necessary public health actions should be conducted for each patient. We also identified priorities for future research into PTB.CONCLUSION: These consensus-based clinical standards will help to improve patient care by guiding clinicians and programme managers in planning and implementation of locally appropriate measures for optimal person-centred treatment for PTB.

Clinical standards for the assessment, management and rehabilitation of post-TB lung disease.

BACKGROUND: Increasing evidence suggests that post-TB lung disease (PTLD) causes significant morbidity and mortality. The aim of these clinical standards is to provide guidance on the assessment and management of PTLD and the implementation of pulmonary rehabilitation (PR).METHODS: A panel of global experts in the field of TB care and PR was identified; 62 participated in a Delphi process. A 5-point Likert scale was used to score the initial ideas for standards and after several rounds of revision the document was approved (with 100% agreement).RESULTS: Five clinical standards were defined: Standard 1, to assess patients at the end of TB treatment for PTLD (with adaptation for children and specific settings/situations); Standard 2, to identify patients with PTLD for PR; Standard 3, tailoring the PR programme to patient needs and the local setting; Standard 4, to evaluate the effectiveness of PR; and Standard 5, to conduct education and counselling. Standard 6 addresses public health aspects of PTLD and outcomes due to PR.CONCLUSION: This is the first consensus-based set of Clinical Standards for PTLD. Our aim is to improve patient care and quality of life by guiding clinicians, programme managers and public health officers in planning and implementing adequate measures to assess and manage PTLD.

Hiperplasia mesonéfrica difusa: a propósito de un caso / Diffuse mesonephric hyperplasia: a case report

La persistencia de restos derivados del mesonefros suele presentarse en las paredes laterales del cérvix de forma frecuente. En cambio, la evolución hacia una hiperplasia mesonéfrica o un carcinoma mesonéfrico es muy poco frecuente. Presentamos a una paciente de 50 años, intervenida de histerectomía por útero miomatoso, en cuya pieza quirúrgica se describe una hiperplasia mesonéfrica difusa. La presencia de restos procedentes del mesonefros o hiperplasia, constituyen en casi la totalidad de las ocasiones un hallazgo benigno que no precisa tratamiento. Es necesario conocer las características de este tipo de lesiones derivadas del mesonefros, para evitar tratamientos innecesarios

The persistence of mesonephric remnants is often present on the side walls of the cervix. However, the evolution towards mesonephric hyperplasia or mesonephric carcinoma is very rare. The case is presented of a 50-year-old female patient, who underwent hysterectomy for myomatous uterus, and in which surgical specimen was described a diffuse mesonephric hyperplasia. The presence of remains from mesonephros or hyperplasia is almost always a benign finding that does not require treatment. It is necessary to know the characteristics of this type of lesion derived from mesonephros, in order to avoid unnecessary treatments

Tuberculosis, COVID-19 and migrants: Preliminary analysis of deaths occurring in 69 patients from two cohorts.

Little is known about the relationship between the COVID-19 and tuberculosis (TB). The aim of this study is to describe a group of patients who died with TB (active disease or sequelae) and COVID-19 in two cohorts. Data from 49 consecutive cases in 8 countries (cohort A) and 20 hospitalised patients with TB and COVID-19 (cohort B) were analysed and patients who died were described. Demographic and clinical variables were retrospectively collected, including co-morbidities and risk factors for TB and COVID-19 mortality. Overall, 8 out of 69 (11.6%) patients died, 7 from cohort A (14.3%) and one from cohort B (5%). Out of 69 patients 43 were migrants, 26/49 (53.1%) in cohort A and 17/20 (85.0%) in cohort B. Migrants: (1) were younger than natives; in cohort A the median (IQR) age was 40 (27-49) VS. 66 (46-70) years, whereas in cohort B 37 (27-46) VS. 48 (47-60) years; (2) had a lower mortality rate than natives (1/43, 2.3% versus 7/26, 26.9%; p-value: 0.002); (3) had fewer co-morbidities than natives (23/43, 53.5% versus 5/26-19.2%) natives; p-value: 0.005). The study findings show that: (1) mortality is likely to occur in elderly patients with co-morbidities; (2) TB might not be a major determinant of mortality and (3) migrants had lower mortality, probably because of their younger age and lower number of co-morbidities. However, in settings where advanced forms of TB frequently occur and are caused by drug-resistant strains of M. tuberculosis, higher mortality rates can be expected in young individuals.

Sobresedación Zero como herramienta de confort, seguridad y gestión en la unidades de cuidados intensivos / Oversedation Zero as a tool for comfort, safety and intensive care unit management

La sedación es necesaria en el tratamiento de los pacientes críticos, tanto para aliviar el sufrimiento como para curar a los pacientes con enfermedades que precisan el ingreso en unidades de cuidados intensivos. Esta sedación debe ser la adecuada a las necesidades del paciente en cada momento de su evolución clínica, ni por debajo (infrasedación) ni por encima (sobresedación). Una sedación adecuada influye en la comodidad, la seguridad, la supervivencia, la calidad de vida posterior, la rotación de camas de las unidades de críticos y los costes. La infrasedación se detecta y corrige rápidamente. Sin embargo, la sobresedación es silente y difícil de prevenir sin unas pautas de actuación, una concienciación colectiva y un trabajo en equipo. El proyecto «Sobresedación Zero» del Grupo de Trabajo de Sedación, Analgesia y Delirium de la Sociedad Española de Medicina Intensiva, Crítica y Unidades Coronarias pretende ser una herramienta docente, práctica y de concienciación colectiva de comodidad, seguridad y gestión para maximizar el resultado clínico y minimizar los efectos perjudiciales de la sedación excesiva. Se basa en un paquete de medidas que se incluye monitorizar el dolor, la analgesia, la agitación, la sedación, el delirium y el bloqueo neuromuscular, mantener a los pacientes sin dolor, realizar una sedación dinámica según objetivos clínicos, consensuar el protocolo multidisciplinar a seguir y evitar la sedación profunda no indicada clínicamente

Sedation is necessary in the management of critically ill patients, both to alleviate suffering and to cure patients with diseases that require admission to the intensive care unit. Such sedation should be appropriate to the patient needs at each timepoint during clinical evolution, and neither too low (undersedation) nor too high (oversedation). Adequate sedation influences patient comfort, safety, survival, subsequent quality of life, bed rotation of critical care units and costs. Undersedation is detected and quickly corrected. In contrast, oversedation is silent and difficult to prevent in the absence of management guidelines, collective awareness and teamwork. The Zero Oversedation Project of the Sedation, Analgesia and Delirium Working Group of the Spanish Society of Intensive and Critical Care Medicine and Coronary Units aims to offer a practical teaching and collective awareness tool for ensuring patient comfort, safety and management with a view to optimizing the clinical outcomes and minimizing the deleterious effects of excessive sedation. The tool is based on a package of measures that include monitoring pain, analgesia, agitation, sedation, delirium and neuromuscular block, keeping patients pain-free, performing dynamic sedation according to clinical objectives, agreeing upon the multidisciplinary protocol to be followed, and avoiding deep sedation where not clinically indicated

Complicaciones de la biopsia transrectal de próstata en nuestro medio. Estudio multicéntrico internacional de 3.350 pacientes / Complications of transrectal prostate biopsy in our context. International multicenter study of 3350 patients

INTRODUCCIÓN: El cáncer de próstata es la neoplasia visceral más frecuente en el varón, y en Estados Unidos es la segunda con mayor mortalidad, por detrás del cáncer de pulmón y por delante del cáncer colorrectal. La mortalidad por cáncer prostático se ha reducido en Estados Unidos, Austria, Reino Unido y Francia, mientras que la supervivencia a los 5 años ha aumentado en Suecia, debido probablemente al incremento de la actividad diagnóstica y a una mayor detección de tumores no mortales. La biopsia transrectal de próstata (BTRP) suele tener una baja tasa de complicaciones graves, con un número de complicaciones menores no despreciable. La mortalidad asociada directamente a este procedimiento es baja y suele estar en el contexto de un shock séptico. Las principales complicaciones derivadas de la biopsia de próstata pueden ser infecciosas (leves o graves) y no infecciosas (hemorragia en forma de hematuria, uretrorragia, rectorragia o hemospermia, retención aguda de orina [RAO], dolor o reacciones vagales). MATERIAL Y MÉTODO: El objetivo del estudio es comparar tres protocolos habituales de BTRP y su relación con la aparición de complicaciones. Estudio retrospectivo multicéntrico observacional realizado en tres países (España, Italia y Portugal). Se revisaron los historiales clínicos de 3.350 varones a los que se ha realizó una BTRP para investigar la existencia de cáncer de próstata, con un control evolutivo mínimo de 6 meses. RESULTADOS: La edad media fue de 65,50 años, mediana 66, rango 43-79. En el análisis de subgrupos se apreció que en los pacientes más jóvenes hubo más RAO (p = 0,0000001). Así mismo, nuestros resultados arrojaron que los pacientes más jóvenes presentaron más dolor relacionado con el procedimiento (p = 0,0000001) que los de mayor edad. En cuanto al PSA, la media fue de 10,44, DE 7,73, mediana 8,15, rango 0,98-68,09. El índice de masa corporal (IMC) más elevado no se asoció a más infección (p = 0,000004). Al realizar el análisis multivariante se comprobó que las variables significativas en el grupo general fueron: edad (p = 0,0013), PSA (p = 0,0402), anestesia con infiltración local (p = 0,0001) y profilaxis con esquema metronidazol +tobramicina +amoxicilina-ácido clavulánico +gentamicina (p = 0,0001), presentando una distribución normal con alto intervalo de confianza (95%) y correlación significativa. La variable más significativa para ninguna complicación y para el dolor es la profilaxis (p = 0,0001), para el sangrado son la edad (p = 0,0013) y la profilaxis (p = 0,0001), para la infección son la edad (p = 0,0013), la profilaxis y el PSA (p = 0,0001), y para la RAO son la edad (p = 0,0013), la anestesia con infiltración local, la profilaxis (p = 0,0001) y el PSA (p = 0,0402). CONCLUSIONES: La aplicación de sedación general tiene menos efectos secundarios y complicaciones relacionadas con el procedimiento de la biopsia transrectal de próstata respecto a la aplicación de anestesia local transrectal. La elección del tipo de pauta de profilaxis antibiótica resulta determinante en la aparición de complicaciones derivadas de la realización de la biopsia transrectal de próstata

INTRODUCTION: Prostate cancer is the most common visceral neoplasm in men and the second one in the United States with the highest mortality behind lung cancer and ahead of colorectal cancer. While prostate cancer mortality rates have been reduced in the United States, Austria, United Kingdom and France, 5-year survival rates have been incremented in Sweden, probably due to a higher diagnostic activity and non-lethal tumor detection. TRPB usually has low rates of serious complications, with a not negligible number of minor complications. Mortality directly associated with this procedure is low and usually related to septic shock. The main complications derived from prostate biopsy can be infectious (mild or severe) and non-infectious (hematuria consistent with hemorrhage, urethral bleeding, rectal bleeding or hemospermia, acute urinary retention, pain or vasovagal reactions). MATERIAL AND METHOD: The objective of the study is to compare three usual TRPB protocols and their relationship with the incidence of complications. Retrospective multicenter observational study conducted in three countries (Spain, Italy and Portugal). We have reviewed the medical records of 3350 men who underwent TRPB to evaluate the existence of prostate cancer, with a minimum evolutionary control of 6 months. RESULTS: The mean age was 65,50 years, median 66, range 43-79. The subgroup analysis showed that younger patients had higher rates of acute urine retention (AUR) (P=.0000001). Likewise, our results revealed that younger patients presented more procedural pain (P=.0000001) than older PATIENTS: Regarding PSA, the mean value was 10.44, SD 7.73, median 8.15, range 0.98-68.09. A higher body mass index (BMI) was not associated with further infection (P=.000004). When performing the multivariate analysis, it was found that the significant variables in the general group were: age (P=.0013), PSA (P=.0402), local infiltration anesthesia (P=.0001) and prophylaxis with metronidazole +tobramycin +amoxicillin/clavulanic acid +gentamicin (P=.0001), presenting a normal distribution with high confidence interval (95%) and significant correlation. Prophylaxis is the most significant variable for no complications and pain (P=.0001), age (P=.0013) and prophylaxis (P=.0001) are for bleeding, age (P=.0013), prophylaxis and PSA (P=.0001) are for infection, and finally, age (P=.0013), anesthesia with local infiltration and prophylaxis (P =.0001) and PSA (P=.0402) are for AUR. CONCLUSIONS: Sedation has fewer side effects and complications related to the transrectal prostate biopsy procedure with respect to transrectal local anesthesia. The choice of the antibiotic prophylaxis scheme is decisive in the onset of complications arising from the performance of a transrectal prostate biopsy

CONCLUSIÓN: La sospecha diagnóstica de estas anomalías se basa en los hallazgos clínicos, de ahí la importancia del conocimiento de los mismos para implementar cuanto antes un tratamiento efectivo en la esfera estomatológica

BACKGROUND: Marfan-Like syndrome is a congenital pathology that does not meet all Marfan syndrome criteria. Describing its phenotype allows us to make a diagnosis of suspicion. Case description. Authors expose the clinical manifestations observed in a girl with a mutation in the COL5A1 gene not described at the present time. These alterations are muscular hypotonia and articular hypermobility, attention deficit, scoliosis, flat feet valgus, elongated and myopathic facies, antimongoloid slant, detached atrial pavilions, mild exophthalmos and bilateral ptosis, astigmatism, cleft palate, micrognathia, compressed palate, dental crowding, early emergence and altered sequence of eruption in both dentitions. CONCLUSIONS: Clinical diagnosis of suspicion is based on the clinical findings, hence the importance of the knowledge of them to implement precociously an effective treatment in the stomatological área

Tratamiento farmacológico de la obesidad para médicos de Atención Primaria / Pharmacological treatment of obesity for Primary Care physicians

La obesidad es una enfermedad de alta prevalencia en las consultas de Atención Primaria. Se asocia a comorbilidades mayores (dislipidemia, diabetes, hipertensión) que aumentan la morbimortalidad, el gasto sanitario y disminuye la calidad de vida de los pacientes. Los cambios en el estilo de vida siguen siendo los pilares del tratamiento del exceso de peso. Debemos plantearnos tratamiento farmacológico cuando hay dificultades para alcanzar objetivos de pérdida de peso. En este artículo revisamos los fármacos autorizados actualmente para el tratamiento de la obesidad y del sobrepeso con comorbilidades mayores

Obesity is a disease of high prevalence in Primary Care clinics. It is associated with major comorbidities (dyslipidaemia, diabetes, hypertension) that increase morbidity and mortality, health expenditure, and reduces the quality of life of patients. Changes in lifestyle are still the pillars of the treatment of excess weight. Pharmacological treatment should be considered when there are difficulties in achieving weight loss goals. In this article, a review is presented on the currently authorised drugs for the treatment of obesity and overweight with major comorbidities

Cuatro años de experiencia clínica con radio-223 para el tratamiento del cáncer de próstata resistente a la castración / Four years of clinical experience with Radium-223 for the treatment of castration-resistant prostate cancer

El dicloruro de radio-223 es un radiofármaco emisor alfa que prolonga la supervivencia global en pacientes con cáncer de próstata resistente a la castración y metástasis óseas sintomáticas. Presentamos un análisis retrospectivo de 68 pacientes tratados. MÉTODO: Se evaluó la incidencia de eventos adversos hematológicos, gastrointestinales y otros, incluidos aquellos que llevaron a la interrupción o el retraso del tratamiento. Se determinó la mejoría o empeoramiento del dolor óseo, los niveles de antígeno prostático específico y de fosfatasa alcalina sérica. Se valoró la gammagrafía ósea pre- y postratamiento y se correlacionó con la evolución clínica. RESULTADOS: Fueron incluidos 68 pacientes. La media del número de inyecciones de radio-223 fue de 5 (rango 1-6), el 69% de los pacientes recibieron 5 o 6 inyecciones. Los efectos secundarios más comunes fueron alteraciones digestivas en 24 pacientes, anemia en 7 y trombocitopenia en 5. Se observaron claras tendencias a la baja en la fosfatasa alcalina sérica. La fosfatasa alcalina sérica media disminuyó desde el inicio en el 77% de los pacientes y el antígeno prostático específico en menos del 40%. La mayoría de los pacientes (62) experimentaron una mejoría en la intensidad o estabilidad del dolor. No se observó ningún fenómeno de llamarada de antígeno prostático específico. CONCLUSIONES: El radio-223 fue generalmente bien tolerado y no hubo problemas de seguridad. Los eventos adversos fueron leves y manejables. Fue más común una disminución en la fosfatasa alcalina sérica que del antígeno prostático específico. La monitorización de la dinámica de la fosfatasa alcalina sérica puede ser útil

PURPUSE: Radium-223 is an alpha-emitting radiopharmaceutical that significantly prolongs overall survival in patients with castration-resistant prostate cancer and symptomatic bone metastases. We report a retrospective analysis of our clinical experience with Radium-223 in the first 68 patients treated. METHODS: The incidence of hematologic, gastrointestinal, and other adverse events was identified, including events that led to treatment discontinuation or delay. Alterations in bone pain and prostate-specific antigen and serum alkaline phosphatase levels were evaluated. Bone scan changes were identified and correlated with the clinical course. RESULTS: Sixty-eight patients were included in the study. The median number of radium-223 injections was 5 (range 1-6), with 69% of patients receiving 5 to 6 injections. The most common side effects were digestive alterations in 24 patients, anemia in 7 patients, and thrombocytopenia in 5 patients. Clear downward trends in serum alkaline phosphatase were seen, that were less clear in prostate-specific antigen. Mean serum alkaline phosphatase decreased from baseline in 77% of the patients, and prostate-specific antigen in less than 40%. The majority of patients (62) experienced an improvement in bone pain intensity or no increase in bone pain intensity. No prostate-specific antigen flare phenomenon was noted. CONCLUSIONS: Radium-223 was generally well tolerated and there were no safety concerns. The adverse events were mild and manageable. A decline in serum alkaline phosphatase was more common than a decline in prostate-specific antigen. Monitoring changes in serum alkaline phosphatase dynamics may be useful

Biopsia selectiva de ganglio centinela en carcinomas de mama N+ convertidos a N0 después de quimioterapia neoadyuvante / Sentinel lymph node biopsy in N+ breast cancer with conversion into N0 after neoadjuvant chemotherapy

OBJETIVO: Valorar la utilidad de la biopsia selectiva del ganglio centinela (BSGC) en pacientes con carcinoma de mama N+ convertidas a N0 tras recibir quimioterapia neoadyuvante. MATERIAL Y MÉTODOS: Análisis descriptivo incluyendo 16 mujeres diagnosticadas de carcinoma infiltrante de mama con metástasis linfáticas confirmadas por biopsia y portadoras de marcador metálico (MM) en el ganglio patológico. Recibieron quimioterapia neoadyuvante con respuesta radiológica completa ganglionar. Se realizó linfogammagrafía tras inyección 99mTc-nanocoloides, obteniéndose imágenes planares y SPECT/TC, analizando el drenaje linfático y la concordancia del ganglio centinela (GC) con el MM. RESULTADOS: El GC se visualizó en la linfogammagrafía en el 93,7% de los casos. El GC coincidió con el MM en 12/15 en la SPECT/TC. Se completó la técnica de BSGC en 14/16, localizando intraoperatoriamente el GC en todas ellas. El GC fue negativo en 10 pacientes, 3 presentaron macrometástasis y una micrometástasis, realizándose linfadenectomía axilar a los casos con macrometástasis>15.000cp/μARNm CK-19, ausencia de drenaje y uno de los no coincidentes con el MM por encontrarse en diferentes niveles de Berg. Estos 2 últimos con resultado positivo para metástasis. En los otros casos de no coincidencia con el MM se extirparon en total 4 ganglios linfáticos, sin evidencia de metástasis. A las pacientes que no se les practicó linfadenectomía axilar se les hizo seguimiento medio de 10 meses (rango 6-17), sin evidencia de afectación ganglionar. CONCLUSIONES: La BSGC en el cáncer de mama con conversión a N0 post-neoadyuvancia presenta buenos resultados y una baja tasa de falsos negativos

OBJECTIVE: Sentinel lymph node biopsy (SLNB) usefulness in breast carcinoma N+ converted to N0 after neoadjuvant chemotherapy (NC). MATERIAL AND METHODS: Descriptive study including 16 females with infiltrating carcinoma with lymphatic metastasis confirmed by biopsy, leaving a metallic marker (MM) in pathological lymph nodes (LN). All patients underwent NC reaching a complete radiological response in LN. Lymphoscintigraphy was performed after 99mTc nanocoloid injection, obtaining planar images and SPECT/CT. Lymphatic drainage and concordance of sentinel node (SN) with MM was analyzed. RESULTS: SN was visualized in lymphoscintigraphy in 93.7% of cases. The SN coincided with the MM in 12/15 cases on SPECT/CT. The SLNB technique was completed on 14/16 patients, intraoperatively locating the GC in all of them. The SN was negative in 10 cases, 3 cases presented macrometastases and 1 micrometastases. Axillary lymphadenectomy (AL) was performed in a case of macrometastasis with>15,000cp/μARNm CK-19, absence of drainage and in one case that showed no coincidence with the MM due different Berg′s level location. These last two cases presented lymph node metastasis. In the other two cases with not coincidence between the SN and the MM, a total of 4 lymph nodes were removed, showing no evidence of metastasis. Patients without AL were followed up for an average of 10 months (range 6-17), with no evidence of lymph node involvement. CONCLUSION: SLNB in breast cancer with conversion into N0 after neoadjuvant treatment is a technique with good results and a low false negative rate

Evolución de las derivaciones desde Atención Primaria a Urología tras la creación de un grupo de trabajo y la instauración de protocolos y cursos de formación continuada / Analysis of referrals after a synergic work between primary care and urology. Impact of joint protocol implementation and a continuing education program in our healthcare area

Objetivo: Analizar la evolución y adecuación de las derivaciones de Atención Primaria a Urología tras la implantación de protocolos sobre las enfermedades urológicas más frecuentes y la instauración de un programa de formación continuada. Material y métodos: En el 2011 se creó un grupo de trabajo Atención Primaria-Urología. Se instauraron inicialmente protocolos de actuación y práctica clínica en enfermedad prostática (HBP y PSA), que se apoyaron con sesiones formativas a los médicos de Atención Primaria. Tras analizar su efecto, en el 2015 se añadieron otros 3(enfermedad escrotal, infecciones urinarias e incontinencia urinaria). Analizamos y comparamos las derivaciones y su adecuación antes y después de la instauración. Resultados: El motivo más frecuente de derivación son los síntomas del tracto urinario inferior (STUI) por HBP que, inicialmente, suponían un 22,8% del total, y que han disminuido al 16,9%. Tras la introducción de los demás algoritmos, observamos una disminución de las derivaciones sobre enfermedad escrotal (del 13-14 al 7,8%), que permanecen estables (en torno al 10%) las relacionadas con infecciones urinarias y que aumentan las derivaciones por incontinencia urinaria (del 3 al 10,3%). La adecuación a los protocolos fue mejorando progresivamente en las relacionadas con STUI (del 46 al 65,3%); en PSA (del 55 al 84,4%) y en incontinencia urinaria (del 66,2 al 73,1%). Descendió la adecuación en cuanto a enfermedad escrotal (del 67,1 al 63,3%) y se mantuvo similar en ITU (en torno al 76%). Conclusiones: El trabajo conjunto entre Urología y Atención Primaria consigue mejorar la adecuación de las derivaciones en las enfermedades urológicas más frecuentes

Objective: To analyse the evolution and adequacy of referrals from Primary Care to Urology, after the implementation of referral protocols on the most frequent urological diseases and the establishment of a continuing education program. Material and methods: A Primary Care-Urology work group was created in 2011. Initially, performance and clinical practice protocols in prostatic pathology (BPH and PSA) were established. These were supported by training sessions for primary care physicians. After analysing the effect of the mentioned joint work, 3more (scrotal pathology, urinary tract infections and urinary incontinence) were included. We analysed and compared the referrals and their adequacy before and after the establishment of the protocols. Results: The most common referral causes were symptoms of the lower urinary tract due to BPH, which initially represented 22.8% of the total, and decreased to 16.9%. After the introduction of the new algorithms, we observed a decrease in referrals for scrotal pathology (13-14% to 7.8%), an increase in urinary incontinence referrals (3% al 10.3%) and those related to urinary tract infections remained stable. The adequacy to the protocols improved progressively: LUTS from 46% to 65.3%; PSA from 55% to 84.4% and urinary incontinence from 66.2% to 73.1%. Adequacy in scrotal pathology decreased (de 67.1% a 63.3%), while in UTI it stayed much the same (around 76%). Conclusions: The joint work between Urology and Primary Care achieves an improvement in referrals adequacy regarding the most frequent urological pathologies

Evolución de la resistencia a antibióticos de microorganismos causantes de infecciones del tracto urinario: un estudio de vigilancia epidemiológica de 4 años en población hospitalaria / Evolution of the antibiotic-resistance of microorganisms causing urinary tract infections: A 4-year epidemiological surveillance study in a hospital population

Antecedentes: La infección del tracto urinario (ITU) es la primera causa de infección en pacientes con ingreso hospitalario. En este trabajo describimos los patógenos más frecuentemente implicados en el desarrollo de ITU en pacientes hospitalizados, su perfil de sensibilidad antibiótica y la evolución de la actividad de los antibióticos de uso habitual en el tratamiento de estas infecciones. Métodos: Se evaluaron retrospectivamente los resultados de los cultivos y antibiogramas de las muestras de orina procedentes de pacientes adultos ingresados en el Complejo Hospitalario Virgen de las Nieves (Granada, España) con confirmación microbiológica de ITU entre enero de 2013 y diciembre de 2016. Resultados: Se identificaron 4.347 microorganismos (3.969 bacterias y 378 levaduras). Durante los 4años de estudio, y en ambos sexos, Escherichia coli fue la especie más frecuentemente aislada; sin embargo, el 62,9% de las ITU estuvieron causadas por microorganismos diferentes a este. La presencia de microorganismos multirresistentes como Acinetobacterspp. (1,2%) y de enterobacterias productoras de betalactamasas de espectro extendido (10,0%) y de carbapenemasas (0,3%) fueron también hallazgos relevantes. Imipenem, piperacilina-tazobactam y fosfomicina presentaron tasas de actividad por encima del 80%, considerando todos los microorganismos causantes de ITU, mientras que el resto de antibióticos ensayados presentaron porcentajes de actividad inferiores al 70%. Conclusión: Imipenem y piperacilina-tazobactam fueron los antibióticos de uso hospitalario más activos, lo que los convierte en antibióticos de primera línea en el tratamiento empírico de la ITU en este ámbito sanitario. El uso de otros antibióticos debería estar limitado a situaciones de sensibilidad demostrada o muy probable

Background: Urinary tract infections (UTIs) are the leading cause of infection in hospitalised patients. In this study, we describe the most common pathogens involved in the development of UTIs in hospitalised patients, their antibiotic-sensitivity profile and the activity evolution of antibiotics in standard use for treating these infections. Methods: We retrospectively assessed the results of cultures and antibiograms from urine samples from adult patients hospitalised in the Hospital Complex Virgen de la Nieves (Granada, Spain) with a microbiological confirmation of UTI between January 2013 and December 2016. Results: We identified 4,347 microorganisms (3,969 bacteria and 378 yeasts). During the 4years of the study, Escherichia coli was the most common species isolated in both sexes; however, 62.9% of the UTIs were caused by other microorganisms. The presence of multiresistant microorganisms such as Acinetobacterspp. (1.2%) and extended-spectrum beta-lactamase-producing enterobacteria (10.0%) and carbapenemase-producing enterobacteria (0.3%) were also relevant findings. Imipenem, piperacillin-tazobactam and fosfomycin presented activity rates above 80%, considering all causal microorganisms of UTI, while the other tested antibiotics presented activity rates below 70%. Conclusion: Imipenem and piperacillin-tazobactam were the most active antibiotics in hospital use, which makes them first-line antibiotics in the empiric treatment of UTIs in this healthcare setting. The use of other antibiotics should be limited to conditions of demonstrated or highly probable sensitivity

Complicaciones a mediano plazo de la prótesis monopolar modular de cabeza radial / Mid-term complications of the monopolar, modular radial head prosthesis

Resumen: Introducción: El objetivo de este estudio es evaluar el tipo, la frecuencia y la gravedad de las complicaciones después de la implantación de la prótesis monopolar modular de cabeza radial. Material y métodos: Se revisaron retrospectivamente 47 pacientes con 48 prótesis de cabeza radial implantadas entre 2009 y 2017 durante una media de 43.55 meses (rango: 12-89). Resultados: Se implantó el mismo tipo de prótesis en cada paciente (Ascension Modular Radial Head) . La puntuación media obtenida en la clasificación Mayo Elbow Performance Score fue de 88.29 ± 9.9 puntos. Durante el seguimiento tres pacientes (6.25%) sufrieron dolor continuo. Doce casos (25.5%) mostraron sobredimensión radiológica, aunque sólo cinco fueron sintomáticos. Se detectó osificación heterotópica en 27 casos (57.4%), 11 pacientes (23.4%) desarrollaron rigidez postoperatoria, 19 casos (40.42%) mostraron osteólisis periprotésica, de los cuales siete fueron sintomáticos, 13 pacientes (27%) presentaron complicaciones: tres casos de infección, cuatro casos de aflojamiento sintomático, dos neuroapraxias, una inestabilidad y tres casos de sobredimensionamiento con rigidez asociada. Nueve pacientes (18.75%) fueron reintervenidos. Discusión: Presentamos 27% de complicaciones globales, principalmente relacionadas con la sobredimensión y el aflojamiento protésico y 19% de reintervenciones. Estos resultados son similares a los descritos en estudios previos con variaciones en función del tiempo de seguimiento. Asimismo, se requieren nuevos estudios para evaluar los resultados a largo plazo y la posible progresión de los hallazgos radiográficos. Conclusión: En conjunto, estos datos ponen de manifiesto la necesidad de mejoría tanto de la técnica quirúrgica como del diseño de los implantes.

Abstract: Introduction: The objective of this study is to assess the type, frequency and severity of complications after the implantation of the modular monopolar radial head prosthesis. Material and methods: Forty-seven patients with 48 radial head prostheses implanted between 2009 and 2017 were reviewed retrospectively. Patients were evaluated clinical and radiographically for a mean follow-up of 43.55 months (range: 12-89). Results: The same type of prosthesis was implanted in every patient (Ascension Modular Radial Head). The average score in the Mayo Elbow Performance Score was 88.29 ± 9.9 points. During the follow-up, three patients (6.25%) suffered from continuous pain. Twelve cases (25.5%) showed radiological oversizing, though only five were symptomatic. Heterotopic ossification was detected in twenty-seven cases (57.4%). Eleven patients (23.4%) developed postoperative stiffness. Nineteen cases (40.42%) showed periprosthetic osteolysis, from which seven were symptomatic. Thirteen patients (27%) developed surgery-related complications: three cases of infection, four cases of symptomatic loosening, two neurapraxies, one instability and three cases of oversizing with associated stiffness. Nine patients (18.75%) required reintervention. Discussion: Our study obtains a 27% of overall complications, mostly related to oversizing and prosthetic loosening, and 19% of reinterventions. These results are similar to those presented in previous studies, with variations depending on the time of follow-up. Further research is also required to evaluate long-term results and the potential progression of the radiographic findings. Conclusion: Taken together, these data stress the need for improvement in both the surgical technique and the design of the implants.

Variables asociadas a complicaciones de la punción con aguja fina frente a biopsia con aguja gruesa de las lesiones pulmonares / Variables associated with complications of fine needle puncture against core needle biopsy of pulmonary injuries

Introducción. El cáncer de pulmón es la primera causa de muerte por cáncer contando con terapias específicas que exigen identificar estructuras moleculares; por ello se utiliza más biopsia aguja gruesa, pudiendo aumentar el riesgo de complicaciones. El objetivo es comparar tasa de complicaciones de punción aguja fina (PAAF) frente a biopsia aguja gruesa (BAG) y analizar variables asociadas. Material y método. Análisis retrospectivo observacional de 146 pacientes con lesiones pulmonares periféricas, practicando PAAF o BAG guiada con técnicas de imagen. El periodo de estudio (marzo 2012-septiembre 2013), durante la primera mitad se realizó PAAF y durante la segunda BAG. Se calculó la tasa de complicaciones y se analizaron variables relativas al tamaño y localización lesión, técnica y presencia de enfisema. El estudio estadístico se realizó mediante un análisis univariado seguido de un modelo de regresión logística. Resultados. Se realizó PAAF en 66 pacientes (45,2%) y BAG en 80 (54,8%). Tasa global complicaciones 36,3% (53 casos), siendo neumotórax la más frecuente 43 casos (29,5%). La tasa de complicaciones fue menor en BAG que PAAF (28,8% vs 45,5%) (p= 0,037) en análisis univariado. En análisis multivariado las variables que asociaron mayor probabilidad complicaciones fueron: número pases ≥ 3 (OR 0,57), tamaño lesión < 30 mm (OR 3,45) y distancia lesión-pleura > 15 mm (OR 0,94). Conclusiones. Los factores que asociaron de forma independiente complicaciones fueron tamaño lesión, distancia lesión-pleura y número pases. La menor tasa complicaciones de BAG se explica por el menor número de pases realizados

Introduction. Lung cancer is the leading cause of cancer death, with specific therapies that require identification of molecular structures; therefore, a core needle biopsy is used, which can increase the risk of complications. The objective is to compare the rate of complications of fine needle puncture (FNP) versus core needle biopsy (CNB) and analyze associated variables. Material and method. Retrospective observational analysis of 146 patients with peripheral pulmonary lesions, practicing FNP or CNB guided with imaging techniques. Study period (March 2012-September 2013), during the first half FNP was carried out and during the second CNB. The complication rate was calculated and variables related to size and location of the lesion, technique and presence of emphysema were analyzed. The statistical study was carried out through a univariate analysis followed by a logistic regression model. Results. FNP was performed in 66 patients (45.2%) and CNB in 80 (54.8%). Overall rate complications 36.3% (53 cases) with pneumothorax being the most frequent 43 cases (29.5%). The complication rate was lower in CNB than FNP (28.8% vs 45.5%) (p= 0.037) in univariate analysis. In multivariate analysis, variables that associated the highest probability of complications were: number of passes ≥ 3 (OR 0.57), lesion size < 30 mm (OR 3.45) and lesion-pleura distance > 15 mm (OR 0.94). Conclusions. Factors that independently associated complications were lesion size, lesion-pleura distance and number of passes. The lower complication rate of BAG is explained by lower number of passes made

Clinical and immunological profile of children aged 5-9 years with persistent egg allergy before oral immunotherapy with egg. A multicenter, randomized controlled trial of the Spanish Society of Pediatric Allergy, Asthma and Clinical Immunology (SEICAP)

BACKGROUND: In children with egg protein allergy (EA), the probability of overcoming the allergy decreases with age, and the possibility of suffering severe adverse reactions as a consequence of dietetic transgressions results in worsened quality of life. One treatment option in such cases is oral immunotherapy (OIT) with foods. METHODS: We present a cohort of children with EA scheduled for OIT with pasteurized raw egg white, describing their clinical and allergic characteristics before the start of OIT. RESULTS: The median age was six years, and 93% of the patients also suffered other allergies (58% asthma and 38.6% allergy to more than two food groups). In the last year, 14.8% had suffered a severe reaction due to dietetic transgression with egg. The median IgE specific of egg white titer was 38.5 kU/l. A double-blind placebo-controlled food challenge with cooked egg white was performed, and if the test proved positive, it was repeated with pasteurized raw egg white. The mean symptoms-provoking dose was 1.26 g and 0.55 g for cooked egg white and raw egg white, respectively. An IgE specific of ovomucoid titer of <2.045 kU/l differentiated those patients that tolerated cooked egg white. CONCLUSIONS: OIT with egg is regarded as an option in patients with persistent egg allergy. In the previous challenge test, an IgE specific of ovomucoid titer of <2.045 kU/l differentiates those patients that tolerate cooked egg white
