In vitro activity of cefiderocol and other newly approved antimicrobials against multi-drug resistant Gram-negative pathogens recovered in intensive care units in Spain and Portugal.

OBJECTIVE: The antimicrobial resistance is a significant public health threat, particularly for healthcare-associated infections caused by carbapenem-resistant Gram-negative pathogens which are increasingly reported worldwide. The aim of this study was to provide data on the in vitro antimicrobial activity of cefiderocol and that of commercially available comparator antibiotics against a defined collection of recent clinical multi-drug resistant (MDR) microorganisms, including carbapenem resistant Gram-negative bacteria collected from different regions in Spain and Portugal. METHODS: A total of 477 clinical isolates of Enterobacterales, Pseudomonas aeruginosa, Acinetobacter baumannii and Stenotrophomonas maltophilia were prospectively (n=265) and retrospectively (n=212) included (2016-2019). Susceptibility testing was performed using standard broad microdilution and results were interpreted using CLSI-2021 and EUCAST-2021 criteria. RESULTS: Overall, cefiderocol showed a good activity against Enterobacterales isolates, being 99.5% susceptible by CLSI and 94.5% by EUCAST criteria. It also demonstrated excellent activity against P. aeruginosa and S. maltophilia isolates, all being susceptible to this compound considering CLSI breakpoints. Regarding A. baumannii (n=64), only one isolate was resistant to cefiderocol. CONCLUSIONS: Our results are in agreement with other studies performed outside Spain and Portugal highlighting its excellent activity against MDR gram-negative bacteria. Cefiderocol is a therapeutic alternative to those available for the treatment of infections caused by these MDR bacteria.

A hybrid approach: a safe option for surgical treatment of early-stage cervical cancer.

OBJECTIVE: The aim of the study was to describe the surgical treatment of early-stage cervical cancer (CC) via minimally invasive surgery (MIS) and a sequential hybrid approach combining MIS and mini-Pfannenstiel. Evaluate sentinel lymph node (SLN) detection using a hybrid tracer (ICG-99m Tc nanocolloid). PATIENTS AND METHODS: Prospective, observational, descriptive, single-center study conducted at Son Espases University Hospital between January 2019 and September 2021. Patients with early-stage CC (FIGO 2018 IA1 with ILV-IIA1) who underwent surgical treatment with a follow-up of at least one year were included. RESULTS: Thirty early-stage CC patients were included, of whom four (13.3%) were upstaged due to positive SLNs. In these cases, laparotomy was avoided, and paraaortic lymphadenectomy was performed via MIS approach. Twenty-six patients had a radical hysterectomy: 15 underwent a hybrid approach, 10 laparoscopy, and one laparotomy. Patients undergoing laparoscopic surgery had a smaller estimated tumor size than those undergoing the hybrid approach. The overall SLN detection rate was 96.1%, with 88.5% of cases occurring bilaterally. Five out of 26 patients (19.2%) presented SLN macrometastases, and five (19.2%) had atypical drainage. Surgery refined staging in 33.3% (10/30) of cases. No recurrences were reported after an average follow-up of 32 months. CONCLUSIONS: MIS for SLN avoids laparotomy leading to rapid recovery and early adjuvant treatment initiation in nodal metastasis. In our study, tumor size is an important clinical implication in the surgical approach to be used. The hybrid tracer provided a high detection rate and combined the advantages of the two tracers. The hybrid approach has a quick recovery and optimal results.

[Translated article] Relation between the volume of injected cement and the vertebral volume in the clinical outcome and in the appearance of leakage after a percutaneous vertebroplasty.

OBJECTIVES: To assess the connection between the volume of injected cement and the vertebral volume measured through a volumetric analysis with a computed tomography (CT scan) in relation to the clinical result and the appearance of a leakage in patients who underwent a percutaneous vertebroplasty after an osteoporotic fracture. MATERIALS AND METHODS: A prospective study of 27 patients (18 female-9 male) with an average age of 69 years old (50-81), and with a one-year follow-up. The study group presented 41 vertebrae with osteoporotic fractures that were treated with a percutaneous vertebroplasty with a bilateral transpedicular approach. The volume of injected cement was registered in each procedure and it was assessed together with the spinal volume measured through a volumetric analysis with CT scans. The percentage of the spinal filler was calculated. The appearance of cement leakage was proved by means of a simple radiography and a postoperative CT scan in all the cases. The leaks were classified according to the location in relation to the vertebral body (posterior, lateral, anterior and in the disc), and the significance (minor: smaller than the largest diameter of the pedicle; moderate: larger than the pedicle but smaller than the height of the vertebra; major: larger than the height of the vertebra). RESULTS: The average vertebra volume was 26.1cm3, the average volume of the injected cement was 2.0cm3 and the percentage of the average filler was 9%. A total of 15 leaks in 41 vertebrae appeared (37%). The leaks were posterior in 2 vertebrae, vascular in 8 and into the disc in 5 vertebrae. They were deemed as minor in 12 cases, moderate in 1 and major in 2 cases. The preoperative assessment of the pain was as it follows: VAS (8) and Oswestry (67%). The cessation of pain was immediate after a year with the following postoperative results: VAS (1.7) and Oswestry (19%). The only complication was the temporary neuritis with a spontaneous resolution. CONCLUSIONS: The injection of small amounts of cement, lower than the ones referred to by literary sources, obtains clinical results similar to the ones obtained by injecting higher amounts and it reduces the number of cement leaks and further complications.

Adequate timing of diagnostic tests for gastroesophageal reflux in children with esophageal atresia. / Momento adecuado para las pruebas diagnósticas de reflujo esofágico en pacientes con atresia de esófago.

OBJECTIVE: Recent guidelines made recommendations for the management of gastroesophageal reflux in patients with esophageal atresia (EA). However, the timing for some diagnostic tests remained somehow unclear. This investigation studied the tests for gastroesophageal reflux in children aged one year old and children aged two or three. MATERIALS AND METHODS: Patients with EA who underwent Multichannel Intraluminal Impedance-pH monitoring (MII-pH) and endoscopy-histology were studied retrospectively. Patients aged one when the test was performed were the YO group and patients aged two or three years old formed the OL group. Substantially impaired MII-pH was defined as total number of reflux episodes >105 or >85 (depending on age), or reflux index >10%. Substantially impaired endoscopy was defined as erosive esophagitis or Barrett's esophagus. Substantially impaired histology was defined as moderate-severe esophagitis or Barrett's esophagus. Conventional parameters and substantially impaired values of the tests were compared. RESULTS: Twenty-four patients were studied. Twenty-three MII-pH were performed (12 in YO and 11 in OL): percentages of abnormal conventional parameters of MII-pH were not significantly different in both groups. Twenty endoscopies with biopsies were performed (7 in YO and 13 in OL): percentages of esophagitis were not significantly different. Interestingly, 26.9% of all the tests performed in YO were substantially impaired vs. 10.8% of all the tests in OL (χ2 = 2.7; p = 0.1). CONCLUSION: Considering the percentage of alarming results of diagnostic tests in the YO group it would be advisable that patients with EA undergo MII-pH and endoscopy-histology at one year of age.

OBJETIVOS: Recientemente se han publicado recomendaciones para el manejo del reflujo gastroesofágico en pacientes con atresia de esófago (AE). Sin embargo, el momento de realización de algunas pruebas no está completamente aclarado. Esta investigación evalúa las pruebas para reflujo gastroesofágico en niños de 1 año y niños de 2-3 años. MATERIAL Y METODOS: Estudio retrospectivo de pacientes con AE sometidos a impedanciometría-phmetría (IMpH) y a endoscopia-histología. Los pacientes con 1 año en el momento de la prueba formaron el grupo MEN, y los pacientes con 2-3 años, el grupo MAY. Se consideró IMpH sustancialmente alterada aquella con un número total de reflujos >105 o >85 (según la edad), o un índice de reflujo >10%. La endoscopia se consideró sustancialmente alterada si presentaba esofagitis erosiva o esófago de Barrett. La histología se consideró sustancialmente alterada si presentaba esofagitis severa-moderada o esófago de Barrett. Se compararon los parámetros convencionales y los sustancialmente alterados. RESULTADOS: Se estudiaron 24 pacientes. Se realizaron 23 IMpH (12 en el grupo MEN y 11 en el MAY); los porcentajes de los parámetros convencionales patológicos no fueron estadísticamente diferentes en ambos grupos. Se realizaron 20 endoscopias (7 en el grupo MEN y 13 en el MAY); los porcentajes de esofagitis no fueron estadísticamente diferentes. El 26,9% de todas las pruebas en el grupo MEN resultaron sustancialmente alteradas, frente al 10,8% en el MAY (χ2 = 2,7; p = 0,1). CONCLUSION: Teniendo en cuenta el porcentaje de resultados alarmantes en el grupo MEN, sería recomendable realizar una IMpH y una endoscopia con biopsias a los pacientes con AE a la edad de un año.

Anti-endotoxin antibodies consumption in cardiovascular collapse: Pathophysiological concerns.

OBJECTIVE: Abnormal endotoxin activity in critically ill patients has been described in the absence of Gram-negative bacterial (GNB) infection. As disease severity seems to be crucial in the detection of this phenomenon, we decided to assess and compare endotoxin exposure in those patients representing the critical situation: septic shock and cardiogenic shock. DESIGN: Prospective, observational non intervention study. SETTING: Critical Care Department of a University tertiary hospital. PATIENTS: Cardiogenic shock (CS) and septic shock (SS) patients. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Follow-up was performed for the first three days. Inflammatory biomarkers (C-reactive protein, procalcitonin and interleuquin-6) and IgM antiendotoxin-core antibodies titter (IgM EndoCAb) were daily analyzed. Sixty-two patients were included; twenty-five patients with SS and thirty-seven with CS. Microbial etiology was established in 23 SS patients (92%) and GNB were present in 13 cases (52%). Although infection was suspected and even treated in 30 CS patients (81%), any episode could be finally confirmed. EndoCAb consumption was more intense in SS patients, although twenty-two CS patients (59.5%) had IgM anti-endotoxin value below 10th percentile range for healthy people. No statistically significant difference in endotoxin exposure was detected between Gram-positive and Gram-negative infections in the SS group. Endotoxin exposure ability to distinguish between SS and CS was moderate (AUC 0.7892, 95% IC: 0.6564-0.9218). CONCLUSIONS: In the severely ill patient some mechanisms take place allowing endotoxin incursion and therefore blurring the limits of diseases pathophysiology. Our work representatively shows how exposure to endotoxin was not fully capable of distinguishing between CS and SS.

Pain and late-onset of hidradenitis suppurativa can have a negative influence on occupational status and educational level. A cross-sectional study. / [Artículo traducido] El dolor y la aparición tardía de la hidrosadenitis supurativa pueden tener una influencia negativa en el estatus ocupacional y el nivel educativo. Estudio transversal.

BACKGROUND AND OBJECTIVES: Hidradenitis suppurativa (HS) is a chronic and painful condition with negative impact on daily activity. Little information on the impact of disease-specific factors on educational level and occupational status in hidradenitis suppurativa patients has been reported. We sought to identify how disease-specific factors could influence occupational status and educational level in patients with HS. METHODS: Cross-sectional study of patients with HS seen between September 2017 and September 2018. Disease-specific variables were analyzed to find associations in patients with different educational levels and occupational status. RESULTS: Ninety-eight patients were included. Patients with non-university studies had more frequently ≥ 3 affected areas (22.5% [16/73] vs. 4.8% [1/22], p = 0.049), a higher number of painful days (8.5 [SD 8.8] vs. 4.6 [SD 4.8], p = 0.048) and a higher score on the VAS scale (6.7 [SD 2.8] vs. 5.0 [3.3], p = 0.031). Patients from the inactive group had a significantly increased number of painful days (11.2 [SD 10.4] vs. 5.7 [SD 6.2], p = 0.004). This group had a greater number of patients with a history of depression (61.3% [19/31] vs. 27.4% [17/62], p = 0.002) and a higher mean BMI (32.3 [9.1] vs. 28.4 [6.4], p = 0.016). Late disease onset was significantly associated with being «inactive¼ (26.7% [8/31] vs. 6.5% [4/62], p = 0.026). No significant differences between severity scales of HS and educational level or occupational status were found. LIMITATIONS: cross-sectional and single center study. CONCLUSIONS: Pain, ≥ 3 affected areas, history of depression, higher mean BMI, and late onset of HS, are associated with low education level and inactive occupational status.

Primary Cutaneous Lymphoma Registry of the Spanish Academy of Dermatology and Venereology (AEDV): Data for the First 5 Years. / Registro de linfomas cutáneos primarios (RELCP) de la AEDV: datos tras 5 años de funcionamiento.

BACKGROUND AND OBJECTIVE: Primary cutaneous lymphomas (PCL) are uncommon. Observations based on the first year of data from the Spanish Registry of Primary Cutaneous Lymphomas (RELCP, in its Spanish abbreviation) of the Spanish Academy of Dermatology and Venereology (AEDV) were published in February 2018. This report covers RELCP data for the first 5 years. PATIENTS AND METHODS: RELCP data were collected prospectively and included diagnosis, treatments, tests, and the current status of patients. We compiled descriptive statistics of the data registered during the first 5 years. RESULTS: Information on 2020 patients treated at 33 Spanish hospitals had been included in the RELCP by December 2021. Fifty-nine percent of the patients were men; the mean age was 62.2 years. The lymphomas were grouped into 4 large diagnostic categories: mycosis fungoides/Sézary syndrome, 1112 patients (55%); primary B-cell cutaneous lymphoma, 547 patients (27.1%); primary CD30+lymphoproliferative disorders, 222 patients (11%), and other T-cell lymphomas, 116 patients (5.8%). Nearly 75% of the tumors were registered in stage I. After treatment, 43.5% achieved complete remission and 27% were stable at the time of writing. Treatments prescribed were topical corticosteroids (1369 [67.8%]), phototherapy (890 patients [44.1%]), surgery (412 patients [20.4%]), and radiotherapy (384 patients [19%]). CONCLUSION: The characteristics of cutaneous lymphomas in Spain are similar to those reported for other series. The large size of the RELCP registry at 5 years has allowed us to give more precise descriptive statistics than in the first year. This registry facilitates the clinical research of the AEDV's lymphoma interest group, which has already published articles based on the RELCP data.

Pain and Late-Onset of Hidradenitis Suppurativa Can Have a Negative Influence on Occupational Status and Educational Level. A Cross-Sectional Study.

BACKGROUND AND OBJECTIVES: Hidradenitis suppurativa is a chronic and painful condition with negative impact on daily activity. Little information on the impact of disease-specific factors on educational level and occupational status in hidradenitis suppurativa patients has been reported. We sought to identify how disease-specific factors could influence occupational status and educational level in patients with hidradenitis suppurativa. METHODS: Cross-sectional study of patients with hidradenitis suppurativa seen between September 2017 and September 2018. Disease-specific variables were analyzed to find associations in patients with different educational levels and occupational status. RESULTS: Ninety-eight patients were included.

Patients from the inactive group had a significantly increased number of painful days (11.2 [SD 10.4] vs 5.7 [SD 6.2], p=0.004). This group had a greater number of patients with a history of depression (61.3% [19/31] vs 27.4% [17/62], p=0.002) and a higher mean BMI (32.3 [9.1] vs 28.4 [6.4], p=0.016). Late disease onset was significantly associated with being "inactive" (26.7% [8/31] vs 6.5% [4/62], p=0.026). No significant differences between severity scales of hidradenitis suppurativa and educational level or occupational status were found. LIMITATIONS: cross-sectional and single center study. CONCLUSIONS: Pain, ≥3 affected areas, history of depression, higher mean BMI, and late onset of hidradenitis suppurativa, are associated with low education level and inactive occupational status.

Relation between the volume of injected cement and the vertebral volume in the clinical outcome and in the appearance of leakage after a percutaneous vertebroplasty. / Relación entre el volumen de cemento inyectado y el volumen vertebral en el resultado clínico y en la aparición de fugas tras vertebroplastia percutánea.

Contributions to the revision of the genus Entoloma (Basidiomycota, Agaricales) in Europe: six new species from subgenus Cyanula and typification of E. incarnatofuscescens.

In anticipation of a phylogenetically revised monograph of Entoloma in Europe, six new species of subgenus Cyanula are described here. Entoloma cistocruentatum is associated with Cistus in Spain, E. dislocatum occurs in montane regions in Catalonia (Spain) and Tuscany (Italy), E. indikon is known from Denmark and three species are mainly distributed in the Nordic countries in Europe: E. calceus, E. perchalybeum and E. praecipuum. Entoloma incarnatofuscescens, from the /Rusticoides clade is neotypified. A fully amended description is given based on molecular evidence, which includes the recently described E. violaceoparkensis and E. klofacianum which became later synonyms.

Impact of the first lockdown related to the COVID-19 pandemic on ophthalmic emergencies in a French University Hospital.

INTRODUCTION: At the beginning of the COVID-19 pandemic, the French government implemented its first national lockdown between March and May 2020 in order to limit the dissemination of the virus. This historic measure affected patients' daily lives and transportation, resulting in changes in the delivery of medical care, particularly emergency care. This study aimed to assess the impact of this restriction policy on the number and severity of ophthalmic emergencies seen in an ophthalmology emergency department. METHODS: This retrospective study conducted at the regional university Hospital of Tours included all patients presenting to the ophthalmology emergency department over four periods: lockdown (03/16/2020 to 05/10/2020), post-lockdown (05/11/2020 to 06/12/2020) and the two corresponding periods in 2019. The following data were recorded: sex, age, time of visit, reason for visit, diagnosis, severity of emergency graded on the BaSe SCOrE, time from first symptoms until visit, existence of a work-related injury, and referral source (ophthalmologist or other). RESULTS: A total of 1186 and 1905 patients were respectively included during the 2020 lockdown period and the corresponding period in 2019. The study populations for the 2019 and 2020 post-lockdown periods consisted of 1242 and 1086 patients respectively. During the lockdown, the number of consultations decreased significantly (-37.7%), affecting mild and severe emergencies similarly. During the post-lockdown period, the number of emergencies gradually increased but did not reach the level of the corresponding period in 2019 (-12.6%). CONCLUSION: The first French lockdown resulted in a significant decrease in ophthalmic emergency visits, similar for all levels of severity. All age groups were impacted similarly, without the expected exaggerated decrease for patients over 50 years of age, who are considered to be at greater risk for developing a severe form of COVID-19. The post-lockdown period showed a gradual increase in ophthalmic emergency visits, although these remained fewer than the previous year.

En bloc resection vs. Gips procedure in pilonidal sinus surgery. / Resección en bloque vs. técnica de Gips en cirugía del sinus pilonidal.

INTRODUCTION: Pilonidal sinus (PS) is an infectious/inflammatory condition of the sacrococcygeal region, with frequent relapses. There is no clear consensus as to which management technique is best. The most widely used technique is en bloc resection (EBR), but less invasive methods (Gips procedure) are now being developed. OBJECTIVE: To compare complications and progression of pediatric patients undergoing PS surgery in our institution using two different surgical techniques. MATERIAL AND METHODS: A retrospective study of patients under 16 years of age undergoing PS surgery (EBR/Gips procedure) for the first time from 2014 to 2020 was carried out. Demographic variables, complications in the first month (exudate, wound infection, dehiscence, and bleeding), and result at the end of follow-up were collected. Qualitative variables were expressed as absolute frequency and percentage, whereas quantitative variables were expressed as mean and standard deviation. RESULTS: 60 patients underwent surgery. EBR was used in the first group, and the Gips procedure was used in the second group (76.67%, n = 46 vs. 23.33%, n = 14). Both were comparable in terms of sex (32.61% vs. 35.71% male), age (14.04 vs. 13.79 years old), and BMI (26.63 vs. 26.20 kg/m2) at surgery. 6 patients underwent re-intervention (10.87% vs. 7.14%; p = 0.684). Median follow-up time to healing was 6.13 ± 0.98 months vs. 3.31 ± 1.26 months (p < 0.024). The Gips procedure caused no dehiscence, whereas dehiscence rate in EBR was 65.22%. CONCLUSION: The Gips procedure is a minimally invasive alternative to EBR. It avoids dehiscence, and time to healing is shorter. Therefore, it should be regarded as the first-line treatment in PS patients.

INTRODUCCION: El sinus pilonidal (SP) es una enfermedad infecciosa/inflamatoria de la región sacrococcígea, que asocia recaídas frecuentes, sin un consenso claro sobre su manejo óptimo. La técnica más empleada es la resección en bloque (RB), pero se están desarrollando métodos menos invasivos (técnica de Gips). OBJETIVOS: Comparar las complicaciones y evolución de pacientes pediátricos intervenidos de SP en nuestro centro con dos técnicas quirúrgicas diferentes. MATERIAL Y METODOS: Estudio retrospectivo de pacientes menores de 16 años intervenidos por primera vez de SP (RB/técnica de Gips) entre 2014 y 2020. Se recogieron variables demográficas, complicaciones en el primer mes (exudado, infección de herida, dehiscencia, sangrado) y resultado al final del seguimiento. Las variables cualitativas se expresaron mediante frecuencia absoluta y porcentaje, y las cuantitativas mediante media y desviación estándar. RESULTADOS: Se intervinieron 60 pacientes: el primer grupo mediante RB y el segundo mediante técnica de Gips (76,67%, n = 46 vs. 23,33%, n = 14). Ambos fueron comparables en cuanto a sexo (32,61% vs. 35,71% varones), edad (14,04 vs. 13,79 años) e IMC (26,63 vs. 26,20 kg/m2) durante la cirugía. Se reintervinieron 6 pacientes (10,87% vs. 7,14%; p = 0,684). La mediana del tiempo de seguimiento hasta la curación fue de 6,13 ± 0,98 vs. 3,31 ± 1,26 meses (p < 0,024). La técnica de Gips no presenta dehiscencias, a diferencia de la RB con un 65,22%. CONCLUSION: La técnica de Gips es una alternativa mínimamente invasiva a la RB, que evita la dehiscencia y precisa menos tiempo en alcanzar la curación, por lo que debería emplearse como tratamiento de primera elección.

Management of congenital and acquired airway pathologies in newborns by a cross-disciplinary committee at a third level hospital. / Manejo de la patología congénita y adquirida de la vía aérea en el neonato por parte de un comité multidisciplinar en un centro terciario.

INTRODUCTION: Neonatal airway examination through flexible/rigid bronchoscopy has proved to be useful in the presence of persistent stridor and extubation failure, as well as to assess complications following cardiac surgery. At our institution, these examinations are carried out by a pulmonologist, a neonatologist, an otorhinolaryngologist, and a pediatric surgeon from the pediatric airway committee, established in 2014. OBJECTIVE: To analyze the airway examinations performed in neonates during their stay at the neonatology/neonatal intensive care unit since the airway committee was established. MATERIAL AND METHODS: A retrospective study of the airway examinations conducted in neonates from 2015 to 2019 was carried out. Clinical and demographic data, number of examinations, indications, findings, and complications were collected. Results are presented as mean and standard deviation. Statistical significance was established at p < 0.05. RESULTS: 92 airway examinations were analyzed in 51 patients (54.9% of whom were female). 51% of the patients were premature. Extubation failure and persistent respiratory symptoms following successful extubation were the most frequent indications for airway examination (35.3%). Stratification by gestational age or weight at birth was not associated with an increased risk of pathological findings at examination (p > 0.05). The most frequent finding was vocal cord paralysis (n = 14; 27.5%). In 10 patients (19.6%), no pathological findings were observed. CONCLUSION: Airway examination is useful in patients with stridor to identify vocal cord paralysis following extubation failure. It also allows congenital airway pathologies to be diagnosed and treated. The number of examinations with no pathological findings was similar to that reported in international series.

INTRODUCCION: La exploración de vía aérea mediante broncoscopia flexible/rígida en el neonato ha demostrado utilidad en el estridor persistente, extubaciones fallidas o para valorar complicaciones tras cirugía cardiaca. En nuestro hospital estas exploraciones son practicadas por un neumólogo, neonatólogo, otorrinolaringólogo y cirujano pediátrico del Comité de Vía Aérea Pediátrica, formado en 2014. OBJETIVO: Analizar las exploraciones de vía aérea practicadas a neonatos durante su estancia en Neonatología/Unidad de Cuidados Intensivos Neonatales desde la constitución del Comité de Vía Aérea. MATERIAL Y METODOS: Estudio retrospectivo de exploraciones de vía aérea practicadas a neonatos de 2015-2019. Se recogen datos clínicos y demográficos, número de exploraciones, indicación, hallazgos y complicaciones. Se presentan las medias con su desviación estándar. Se consideró un resultado estadísticamente significativo cuando p < 0,05. RESULTADOS: Se analizaron 92 exploraciones de vía aérea en 51 pacientes (género femenino: 54,9%). El 51% de los pacientes fueron prematuros. La extubación fallida y la persistencia de sintomatología respiratoria tras una extubación satisfactoria fueron las indicaciones más frecuentes (35,3%). La estratificación por edad gestacional o por peso al nacimiento no se asociaba a un mayor riesgo de presentar hallazgos patológicos en la exploración. El hallazgo más frecuente fue la parálisis de cuerda vocal (n = 14; 27,5%). En 10 pacientes (19,6%) no se encontraron hallazgos patológicos. CONCLUSION: La exploración de la vía aérea es útil en pacientes con estridor postextubación y para identificar parálisis de cuerda vocal tras extubación fallida. Además, permite el diagnóstico y tratamiento de patologías congénitas de la vía aérea.

Usefulness of digestive biopsy in the diagnosis of graft-versus-host disease. / Utilidad de la biopsia digestiva para el diagnóstico de la enfermedad injerto contra huésped.

INTRODUCTION: Graft-versus-host disease (GVHD) is a frequent complication of allogeneic hematopoietic stem cell transplantation (allo-HSCT), with high morbidity and mortality rates. Intestinal clinical signs are unspecific, which means differential diagnosis with infections and drug-related etiology should be carried out. Even though intestinal biopsy is widely considered as the gold standard technique, there is no consensus as to which sampling method is best. OBJECTIVE: To assess the results of the biopsy techniques used in patients with suspected intestinal GVHD. MATERIAL AND METHODS: A retrospective study of patients with suspected intestinal GVHD undergoing allo-HSCT from 2010 to 2019 was carried out. They were assessed through digestive biopsy - esophagogastroduodenal biopsy (upper GI endoscopy - UGIE) or rectal biopsy (colonoscopy or direct biopsy). Quantitative variables, expressed as median and interquartile range, and qualitative variables, expressed as absolute frequency and percentage, were collected. RESULTS: 23 patients were studied, 60.9% of whom were male. Median age at biopsy was 9 years (7-14 years). UGIE was used in 47.8% of patients (n=11), colonoscopy was used in 26.1% of patients (n=6), and direct biopsy was used in 34.8% of patients (n=8), with GVHD positive results in 2 (18.2%), 2 (33.3%), and 4 (50%) patients, respectively. CONCLUSIONS: Samples taken through direct biopsy stand as an effective alternative in GVHD diagnosis.

INTRODUCCION: La enfermedad injerto contra huésped (EICH) es una complicación frecuente de los trasplantes de células precursoras hematopoyéticas alogénicos (alo-TCPH), con gran morbimortalidad. La clínica intestinal es inespecífica, planteando el diagnóstico diferencial con infecciones y etiología medicamentosa. Aunque las biopsias intestinales son el gold standard, no existe consenso sobre la mejor técnica para obtenerlas. OBJETIVO: Evaluar los resultados de las técnicas empleadas para obtener biopsias en pacientes con sospecha de EICH intestinal. MATERIAL Y METODOS: Estudio retrospectivo que incluye pacientes sometidos a alo-TCPH entre 2010 y 2019, con sospecha de EICH intestinal estudiados mediante biopsias digestivas: esofagogastroduodenales (endoscopia digestiva alta - EDA) o rectales (colonoscopia o biopsia directa). Recogimos variables cuantitativas, expresadas como mediana y rango intercuartílico; y cualitativas, expresadas en frecuencia absoluta y porcentaje. RESULTADOS: Estudiamos 23 pacientes (60,9% varones). La mediana de edad en el momento de la biopsia fue 9 años (7-14 años). Empleamos EDA en el 47,8% (n= 11), colonoscopia en 26,1% (n= 6) y biopsia directa en el 34,8% (n= 8); siendo positivas para EICH en 2 (18,2%), 2 (33,3%) y 4 (50%), respectivamente. CONCLUSIONES: Las muestras obtenidas mediante biopsia directa se plantean como una alternativa eficiente en el diagnóstico del EICH.

Long-term evaluation of anabolic and anti-resorptive agents in adults with familial osteoporosis due to pro205ala variant of the col1a1 gene.

INTRODUCTION: Osteogenesis imperfecta (OI) is a rare disorder with variable clinical presentation, commonly caused by mutations in collagen type I genes. OI affects both bone quality and density resulting in fractures and deformity. The effectiveness of bisphosphonates in the treatment of adult OI remains unclear. Small, randomised trials have shown increases in BMD, but without fracture rate reduction. AIM: We report the results of BMD of a family harbouring C 613 C>G substitution in exon 8 of Col1A1 gene leading to Pro205Ala missense variant, as well as the results of long term treatment of a mother and daughter with this mutation.

[Duodenal capillary hemangioma as an atypical cause of iron deficiency. Case report].

Hemangiomas are benign vascular gastrointestinal tumours. They are infrequent, located in the submucosa, and can be asymptomatic or cause intestinal obstruction, anaemia or ferropenia. Their initial diagnosis is usually endoscopic despite the absence of pathognomonic features. Traditionally their treatment has been surgical although endoscopic resection is now possible. We present a case of ferropenia resolved after endoscopic resection of a capillary duodenal hemangioma.

Early identification and optimal management of carbapenem-resistant Gram-negative infection.

BACKGROUND: Carbapenem resistance in Gram-negative bacteria is associated with severe infections in the hospital setting. No uniform screening policy or agreed set of criteria exists within the EU to inform treatment decisions for infections caused by carbapenem-resistant Gram-negative bacteria. AIM: To develop a range of consensus statements to survey experts in carbapenem resistance, to identify potential similarities and differences across the EU and across specialties. METHODS: The survey contained 43 statements, covering six key topics relating to carbapenem-resistant organisms: microbiological screening; diagnosis; infection control implementation; antibiotic stewardship; use of resources; and influencing policy. FINDINGS: In total, 136 survey responses were received (66% infectious disease specialists, 18% microbiologists, 11% intensive care specialists, 4% other/unknown) from France, Germany, Greece, Italy, Spain, and the UK. High, or very high, levels of agreement were seen for all 43 consensus statements, indicating good alignment concerning early identification and optimal management of infection due to carbapenem-resistant organisms. CONCLUSION: We offer the following recommendations: (1) screening is required when a patient may have been exposed to the healthcare system in countries/hospitals where carbapenem-resistant organisms are endemic; (2) rapid diagnostic tools should be available in every institution; (3) all institutions should have a specific policy for the control of carbapenem-resistant organisms, which is routinely audited; (4) clear strategies are required to define both appropriate and inappropriate use of carbapenems; (5) priority funding should be allocated to the management of infections due to carbapenem-resistant organisms; and (6) international co-operation is required to reduce country-to-country transmission of carbapenem-resistant organisms.

Fibrin glue treatment associated or not with diathermy for recurrent tracheoesophageal fistula: our results after more than 20 years' experience. / Tratamiento con adhesivo de fibrina asociado o no a diatermia para las fístulas traqueoesofágicas recurrentes: resultados tras más de 20 años de experiencia.

INTRODUCTION: Recurrent tracheoesophageal fistula (RTEF) is a frequent complication (5-10%) in patients with esophageal atresia (EA). Open RTEF surgery has a high morbidity and mortality, so the endoscopic approach represents a promising alternative. We present the long-term results of fibrin glue (FG) bronchoscopic application in patients with RTEF secondary to EA, which was first used by our team in 1994. MATERIAL AND METHODS: A retrospective review of all patients diagnosed with RTEF following EA repair and treated with FG bronchoscopic application from 1993 to 2019 was carried out. In most cases, diathermy was applied prior to FG sealing. The maximum number of endoscopic sessions was 5. In case of persistent RTEF following the fifth session, open surgery was performed. RESULTS: 14 RTEF patients were treated with FG. In all but the first 3 cases (11 patients, 78.6%), diathermy was applied concomitantly. Mean first treatment day was day 85 of life (range: 14-770). Patients received a mean of 2.1 (1-5) endoscopic sessions. Mean follow-up was 12.1 (10-20) years. Overall success rate was 71.4%, without significant differences according to whether diathermy was concomitantly applied or not (72.7% vs. 66.6%). CONCLUSIONS: Fibrin glue bronchoscopic application associated or not associated with diathermy is an excellent option for RTEF treatment in EA patients. The endoscopic approach should be considered as the first-choice treatment for RTEF.

INTRODUCCION: La fístula traqueoesofágica recurrente (FTER) representa una complicación frecuente (5-10%) en los pacientes con atresia de esófago (AE). La cirugía abierta de FTER implica una alta morbimortalidad, por lo que los abordajes endoscópicos suponen una alternativa prometedora. Presentamos los resultados a largo plazo de la aplicación broncoscópica de adhesivo de fibrina (AF) en pacientes con FTER secundaria a AE, técnica utilizada por primera vez en 1994 por nuestro equipo. METODOS: Revisión retrospectiva de 1993 a 2019, incluyendo a todos los pacientes diagnosticados de FTER tras la reparación de AE, y tratados con aplicación broncoscópica de AF. En la mayoría de los casos se aplicó diatermia previamente al sellado con AF. El número máximo de sesiones endoscópicas se estableció en cinco; en caso de persistir FTER tras la quinta sesión, se procedió a cirugía abierta. RESULTADOS: 14 pacientes con FTER fueron tratados con AF; en todos salvo los primeros 3 casos (11 pacientes, 78,6%) se aplicó diatermia concomitante. El día promedio del primer tratamiento fue el día 85 de vida (14 a 770). Los pacientes recibieron una media de 2,1 (1-5) sesiones endoscópicas. El seguimiento medio fue de 12,1 (10-20) años. El éxito global fue del 71,4%, sin apenas variar con la aplicación o no de diatermia concomitante (72,7% vs. 66,6%). CONCLUSIONES: La aplicación broncoscópica de adhesivo de fibrina asociado o no a diatermia representa una excelente opción para el tratamiento de FTER en pacientes con AE. El abordaje endoscópico debe considerarse como tratamiento de primera elección para FTER.
