RESUMO
La traqueotomía percutánea por dilatación es un procedimiento que se realiza en las unidades de paciente crítico, implica la disección roma de los tejidos pretraqueales, seguida de la dilatación de la tráquea sobre la guía y la inserción de la cánula traqueal mediante la técnica de Seldinger. En las últimas décadas, la evidencia sugiere que, en manos de médicos capacitados, es al menos tan segura como la traqueotomía quirúrgica, con similar incidencia de complicaciones. La selección adecuada de pacientes y el uso de herramientas de seguridad complementarias, como broncoscopio o ultrasonido, disminuyen las tasas de falla y complicaciones. Siendo contraindicaciones absolutas para traqueotomía percutánea por dilatación una anatomía anormal, tumor maligno en el sitio de traqueostomía, coagulopatías o vía aérea difícil. La guía mediante broncoscopia permite la evaluación de la profundidad del tubo endotraqueal, confirma la posición de la aguja en el eje de la tráquea y la adecuada inserción del cable guía y dilatador. Entre sus desventajas destacan que, el sitio de punción está sujeto a sesgo y no puede guiar con precisión la aguja en la penetración de la tráquea. La traqueotomía percutánea guiada por ultrasonido es una alternativa validada en unidades, donde no se cuente con broncoscopia. Es un método rápido, seguro, que permite la identificación de estructuras anatómicas, vasculatura cervical, permite identificar el sitio de la punción y guía la inserción de la aguja en la tráquea. Esta técnica presenta altas tasas de éxito al primer intento, reduciendo significativamente el número de punciones.
Percutaneous dilation tracheostomy is a procedure performed in critical patient units. It involves blunt dissection of the pretracheal tissues followed by dilation of the trachea over the guidewire and insertion of the tracheal cannula using the Seldinger technique. In recent decades, evidence suggests that in the hands of trained physicians it is at least as safe as surgical tracheostomy, with a similar incidence of complications. The proper selection of patients and the use of complementary safety tools such as bronchoscope or ultrasound reduce failure rates and complications. Being absolute contraindications for PDT abnormal anatomy, malignant tumor at the tracheostomy site, coagulopathies, or difficult to treat airway. Bronchoscopy guidance allows evaluation of the depth of the endotracheal tube, confirms the position of the needle in the axis of the trachea and the proper insertion of the guide wire and dilator. Among its disadvantages are that the puncture site is subject to slant and cannot accurately guide the needle into the trachea. In addition, it requires Critical Patient Units with bronchoscope and trained personnel. Ultrasound-guided percutaneous tracheotomy is a validated alternative in units where bronchoscopy is not available. It is a fast, safe method that allows the identification of anatomical structures, cervical vasculature, identifies the puncture site and guides the insertion of the needle into the trachea. With high first-attempt success rates, significantly reducing the number of punctures.

Introducción: La parálisis cordal bilateral en aducción es la segunda causa de estridor congénito y genera una grave obstrucción de la vía aérea, debutando con estridor. La traqueotomía ha sido durante mucho tiempo el gold estándar para el tratamiento de esta afección, no exenta de complicaciones. Existen procedimientos que intentan evitar la traqueotomía, como el split cricoideo anterior posterior endoscópico (SCAPE). Objetivo: Presentar experiencia con SCAPE en pacientes pediátricos como tratamiento alternativo de parálisis cordal bilateral en aducción. Material y Método: Análisis retrospectivo de los resultados quirúrgicos obtenidos en pacientes con parálisis cordal bilateral en aducción tratados con SCAPE entre enero de 2016 y diciembre de 2019 en el Hospital Guillermo Grant Benavente de Concepción, Chile. Resultados: Siete pacientes se sometieron a SCAPE. Todos los pacientes presentaban insuficiencia respiratoria severa, cinco requirieron asistencia ventilatoria mecánica. Seis pacientes tenían el diagnóstico de parálisis cordal bilateral (PCB) congénita y uno PCB secundaria a tumor de tronco cerebral. Cuatro pacientes presentaron comorbilidad de la vía aérea: dos pacientes presentaron estenosis subglótica grado I y dos pacientes presentaron laringomalacia que requirió manejo quirúrgico. Los días promedio de intubación fueron once días. Ningún paciente requirió soporte ventilatorio postoperatorio, sólo un paciente recibió oxigenoterapia nocturna debido a hipoventilación secundaria a lesión de tronco. Ningún paciente ha presentado descompensación respiratoria grave. Un 40% ha recuperado movilidad cordal bilateral. Conclusión: Split cricoideo anteroposterior endoscópico es una alternativa eficaz para tratar el PCB en pacientes pediátricos. Nuestro estudio evidencia que es una alternativa a la traqueotomía, con excelentes resultados y menor morbimortalidad.
Introduction: Bilateral vocal fold paralysis in adduction is the second cause of congenital stridor and generates a serious obstruction of the airway. Tracheostomy has long been the gold standard for the treatment of this condition, but it has inherent complications. There are procedures that try to avoid tracheotomy, such as the endoscopic anterior posterior cricoid split (EAPCS). Aim: Present our experience with EAPCS in pediatric patients as a treatment for bilateral vocal fold paralysis in adduction. Material and Method: Retrospective analysis of the surgical results obtained in patients with bilateral vocal cord paralysis in adduction treated with EAPCS between January 2016 and December 2019 at Guillermo Grant Benavente Hospital in Concepción, Chile. Results: Seven patients underwent EAPCS. All patients had severe respiratory failure, five required mechanical ventilation assistance. Six patients were diagnosed with congenital bilateral cord palsy (BCP) and one BCP secondary to a brainstem tumor. Four patients had airway comorbidity: two patients had grade I subglottic stenosis and two patients had laryngomalacia that required surgical management. The average days of intubation were eleven days. No patient required post op invasive/non-invasive ventilation, only one patient received nocturnal oxygen therapy due to hypoventilation secondary to trunk injury. None of the patients has presented severe respiratory decompensation. Forty percent have recovered bilateral chordal mobility. Conclusion: SCAPE is a cutting-edge and effective alternative to treat PCB in pediatric patients. Our study shows that it is an alternative to tracheotomy, with excellent results and lower morbidity and mortality.

El colesteatoma congénito (CC) es una lesión benigna de epitelio escamoso queratinizado que puede afectar diferentes aéreas del hueso temporal con predominio en el oído medio. El CC es una patología poco frecuente que se presenta en pacientes pediátricos y clínicamente se manifiesta como una lesión blanquecina detrás de un tímpano indemne. La mayoría de los pacientes no presenta historia de hipoacusia, otorrea, infección, perforación o cirugía otológica previa. Se analiza el caso de un prescolar con CC que consultó con trastorno de sueño sin sintomatología otológica, pero con otoscopía alterada como hallazgo clínico. En la resonancia magnética nuclear (RMN) con secuencia de difusión, se evidenciaron hallazgos sugerentes de lesión colesteatomatosa en oído medio. Se realizó tratamiento quirúrgico endoscópico combinado con remoción completa de la lesión compatible histológicamente con CC y reconstrucción funcional con prótesis inactiva con resultado auditivo satisfactorio. El CC requiere alta sospecha diagnóstica por pediatras y otorrinolaringólogos, siendo imprescindible realizar un examen físico acucioso que incluya otoscopía de rutina, aunque el paciente no manifieste síntomas otológicos. El tratamiento es quirúrgico y debe considerar uso de endoscópico para asegurar una extracción completa de la lesión. En algunos casos es requerido realizar una reconstrucción auditiva para asegurar un óptimo resultado funcional.
Congenital cholesteatoma (CC) is a benign lesion of keratinized squamous epithelium that can affect different areas of the temporal bone, predominantly in the middle ear. CC is a rare pathology that occurs in pediatric patients and clinically manifests as a white lesion behind an intact eardrum. Most patients do not have a history of hearing loss, otorrhea, infection, perforation, or previous otologic surgery. The following, is the case of an infant with CC who consulted with a sleep disorder without otological symptoms but with altered otoscopy as a clinical finding. Nuclear magnetic resonance (NMR) with diffusion sequence with findings compatible with a cholesteatomatous lesion in the middle ear. Endoscopic surgical treatment was performed combined with complete removal of the lesion histologically compatible with CC and functional reconstruction with inactive prosthesis with satisfactory hearing results. CC requires high diagnostic suspicion by paediatrics and otorhinolaryngologists, and it is essential to perform a thorough physical examination that includes routine otoscopy even if the patient does not show otological symptoms. Treatment is surgical and endoscopic use should be considered to ensure complete removal of the lesion. In some cases, hearing reconstruction is required to ensure optimal functional results.

La otitis media crónica (OMC) activa y colesteatomatosa se consideraban una contraindicación para el uso de implante coclear (IC) en el pasado. Actualmente, se han propuesto múltiples opciones quirúrgicas para el IC, de acuerdo con las características clínicas del paciente y el tipo de patología otológica prexistente. La cirugía del IC se puede realizar en un tiempo o en etapas, siendo fundamental intervenir un oído seco y estable previo a la instalación definitiva del electrodo para reducir complicaciones y obtener resultados auditivos satisfactorios. El IC es un tratamiento seguro y eficaz en pacientes con OMC. Múltiples reportes internacionales han evidenciado baja tasa de complicaciones mayores y óptimos resultados auditivos funcionales en pacientes con hipoacusia y OMC.
Supurative and cholesteatomatous chronic otitis media (COM) were considered a contraindication to cochlear implant (CI) use in the past. Currently, multiple surgical options have been proposed for CI according to the clinical characteristics of the patient and the type of pre-existing otological pathology. Cochlear implant surgery can be performed in a single time or in stages, being essential to intervene a dry and stable ear prior to the definitive installation of the electrode to reduce complications and obtain satisfactory hearing results. CI is a safe and effective treatment in patients with COM. Multiple international reports have shown a low rate of major complications and optimal functional hearing results in patients with hearing loss and COM.

Introducción: La desviación de la punta nasal suele producir alteración estética y funcional nasal. Generalmente, asocia alteraciones morfológicas de los cartílagos alares, además de dismorfia del cartílago septal. Objetivo: Presentar una técnica quirúrgica alternativa para el tratamiento de la laterorrinia en tercio inferior nasal y sus resultados. Material y Método: Se trataron 27 pacientes con una laterorrinia en punta nasal con la técnica del septum bisagra, incluyendo la colocación de uno o dos injertos de expansión. Describimos el protocolo de anamnesis y exploración que seguimos en estos pacientes y la descripción detallada de la técnica quirúrgica. Resultados: En 19 pacientes se utilizó un injerto de expansión unilateral para completar la técnica y en ocho de forma bilateral. Se obtuvo una puntuación media en la escala visual analógica (EVA) de ventilación de 8,3, con una mejoría de seis puntos, y en la EVA de aspecto estético de 8,1, mejorando en 4,6 puntos. Conclusión: la utilización de la técnica del septum bisagra es beneficiosa para el tratamiento de la desviación de la punta nasal, tanto a nivel funcional como estético. Presenta ciertas diferencias frente a otras técnicas descritas. La indicación se debe adecuar a cada paciente de manera individualizada.
Introduction: Deviation of nasal tip usually produces aesthetic disturbance and nasal ventilation decrease. It is usually associated with alar cartilages morphologic disturbances and dysmorphia of the septal cartilage. Aim: To present an alternative surgical technique for treating laterorrhinia in the nasal inferior third and its outcomes. Material and Method: 27 patients with nasal tip laterorrhinia were treated with the hinge septum technique, including the placement of one or two spreader grafts. We describe the anamnesis and exploration protocol that we carried out in these patients and a detailed description of the surgical procedure. Results: Unilateral spreader graft was used in 19 patients to complete the technique, and bilateral spreader graft was used in eight. The average score in visual analogue scale (VAS) related to nasal flow was 8.3, which means an improvement of six points, and in VAS related to aesthetic appearance the score was 8.1, improving 4.6 points. Conclusion: The use of the hinge septum technique is useful to treat the deviation of the nasal tip in a functional and aesthetic way. There are several differences compared to other described techniques. The indication has to be suitable for each patient individually.

Resumen El plasmocitoma extramedular solitario (PES) es una neooplasia maligna infrecuente caracterizada por una proliferación aislada de células plasmáticas monoclonales en tejido extramedular. La localización más frecuente es en cabeza y cuello con predominio en el territorio rinosinusal, sin embargo, estas lesiones malignas representan menos del 1% de los tumores de esta región anatómica. El diagnostico requiere una alta sospecha clínica, análisis histopatológico acucioso, estudios serológicos y exámenes radiológicos sistémicos de acuerdo a los criterios diagnósticos establecidos en la literatura internacional. Se analiza el caso de un paciente masculino con un PES que se presentó como un tumor de fosa nasal derecha y obstrucción nasal de meses de evolución con hallazgos clínicos e imagenológicos inespecíficos. El diagnóstico definitivo se realizó mediante biopsia endoscópica nasal y estudio histopatológico. El tratamiento fue abordado de manera multidisciplinaria entre otorrinolaringología, hematología y radiooncología. De acuerdo a las guías internacionales, se decidió realizar radioterapia localizada con buen resultado clínico precoz. El PES requiere un abordaje multidisciplinario para lograr un diagnóstico y tratamiento oportuno, siendo imprescindible la exclusión del mieloma múltiple debido a las diferencias terapéuticas y en pronóstico clínico. El tratamiento puede realizarse con radioterapia y/o cirugía, siendo la radioterapia el pilar de tratamiento.
Abstract Solitary extramedullary plasmacytoma (SEP) is a rare malignant neoplasm characterized by isolated proliferation of monoclonal plasma cells in extramedullary tissue. The most frequent location is in the head and neck with a predominance in the rhinosinusal territory; however, these malignant lesions represent less than 1% of the tumors in this anatomical region. The diagnosis requires a high clinical suspicion, careful histopathological analysis, serological studies and systemic radiological examinations according to the diagnostic criteria established in the international literature. We analyze the case of a male patient with SEP that presented as a tumor of the right nostril and nasal obstruction of months of evolution with nonspecific clinical and imaging findings. The definitive diagnosis was made by nasal endoscopic biopsy and histopathological study. The treatment was approached by multidisciplinary teamwork. According to international guidelines, it was decided to perform localized radiotherapy with good early clinical results. SEP requires a multidisciplinary approach to achieve a timely diagnosis and treatment, being essential exclusion of multiple myeloma due to the therapeutic differences and prognosis. Treatment can be done with radiation therapy and/or surgery; radiation therapy is the mainstay of treatment.

BACKGROUND: Many patients with coronavirus disease 2019 (COVID-19) have been diagnosed with computed tomography (CT). A prognostic tool based on CT findings could be useful for predicting death from COVID-19. OBJECTIVES: To compare the chest CT findings of patients who survived COVID-19 versus those of patients who died of COVID-19 and to determine the usefulness the clinical usefulness of a CT scoring system for COVID-19. METHODS: We included 124 patients with confirmed SARS-CoV-2 infections who were hospitalized between April 1, 2020 and July 25, 2020. RESULTS: Whereas ground-glass opacities were the most common characteristic finding in survivors (75%), crazy paving was the most characteristic finding in non-survivors (65%). Atypical findings were present in 46% of patients. The chest CT score was directly proportional to mortality; a score ≥18 was the best cutoff for predicting death, yielding 70% sensitivity (95%CI: 47%-87%). CONCLUSIONS: Our results suggest that atypical lesions are more prevalent in this cohort. The chest CT score had high sensitivity for predicting hospital mortality.

Chronic liver injury leads to advanced fibrosis, cirrhosis, and hepatocellular carcinoma. Genetical cell treatment related to the use of adenovirus (Ads) has proven to be beneficial and efficient in the recovery of hepatic diseases. Nevertheless, they are highly immunogenic and trigger an immune response where interferons type 1 (IFN-I) play a very important role. Three shRNAs against the Interferon-1 receptor (IFNAR1) were designed and cloned in pENTR/U6 plasmid and amplified in DH5α cells. Huh7 cells were transfected with these plasmids in the presence or absence of 1 × 109 viral particles/ml of adenovirus containing the green fluorescent protein gene used as a reporter. Transfection with the shRNA plasmids partially inhibited the IFNAR1 expression. This inhibition substantially decreased antiviral response, demonstrated by the decrease of IFNAR1, IFN-α, and TNF-α gene expression, and the decrease at protein levels of IFNAR1, Protein kinase RNA-activated (PKR), and phosphorylated STAT1, allowing higher adenoviral transduction and transgene expression. Interestingly it was seen shRNA inhibited macrophage activation. These results suggest that the inhibition of the IFN-I pathway could be a strategy to minimize the immune response against Adenoviral vectors allowing higher Adenovirus transduction extending the transgene expression.

Resumen Introducción: La pandemia COVID-19 ha afectado significativamente el uso de los sistemas de salud en todo el mundo y se han reducido las consultas de urgencia por patologías no relacionadas con el virus SARS-CoV-2. Objetivo: Analizar el impacto de la pandemia COVID-19 en las consultas de urgencia otorrinolaringológicas atendidas en el servicio de urgencia de un centro de alta complejidad. Material y Método: Se realizó un estudio retrospectivo en que se analizaron las consultas de urgencia otorrinolaringológicas atendidas entre el 3 de marzo y 31 de diciembre de 2020. Se comparó con los datos obtenidos el año 2019 para determinar los cambios epidemiológicos de la pandemia en curso. Resultados: Se evidenció una notoria disminución en las atenciones de urgencia otorrinolaringológicas desde el inicio de la pandemia COVID-19 (-23,3%). El mayor descenso se observó en el periodo de cuarentena o restricción total de movilidad (-59%). No hubo diferencias significativas entre los antecedentes sociodemográficos, tipo de patología otorrinolaringológica, número de cirugías de urgencias y admisiones hospitalarias en comparación con el periodo anterior. Conclusión: La pandemia COVID-19 ha generado una disminución de las consultas de urgencia otorrinolaringológicas agudizándose en el periodo de restricción total de movilidad impuesta por el gobierno. Si bien no se evidenciaron cambios en el patrón de atenciones predominante con respecto al periodo prepandemia, se estima un aumento de las patologías descompensadas o complicadas a mediano-largo plazo. Se requieren estudios prospectivos para determinar el verdadero impacto de la pandemia en curso.
Abstract Introduction: The COVID-19 pandemic has significantly affected the use of health systems around the world, and emergency consultations for diseases not related to the SARS-CoV-2 virus, have been reduced. Aim: To analyze the impact of the COVID-19 pandemic on emergency otolaryngology consultations attended in the emergency department of a highly complex center. Material and Method: A retrospective study was carried out in which the emergency otolaryngology consultations attended between March 3 and December 31, 2020. These data were analyzed and compared with the data obtained in 2019, to determine the epidemiological changes of the ongoing pandemic. Results: There was a noticeable decrease in ENT emergency care since the beginning of the COVID-19 pandemic (-23.3%). The greatest decrease is recorded in the period of quarantine or total mobility restriction (-59%). There were no significant differences between sociodemographic history, type of ENT pathology, number of emergency surgeries and hospital admissions compared to the previous period. Conclusion: The COVID-19 pandemic has generated a decrease in ENT emergency consultations, exacerbating the period of total mobility restriction imposed by the government. Although no changes were evidenced in the predominant care pattern with respect to the pre-pandemic period, an increase in decompensated or complicated pathologies is estimated in the medium-long term. Prospective studies are required to determine the true impact of the ongoing pandemic.

BACKGROUND: Environmental psychological factors such as mood states can modify and trigger an organic response; depressive disorder is considered a risk factor for oncological development, leading to alterations both in the genesis and in the progression of the disease. Some authors have identified that personality relates to mood since a high score in neuroticism is associated with intense and long-lasting emotions of stress and therefore with the development of depressive behaviors. The objective of this study was to analyze the relationship between personality and depression in skin cancer patients. METHODS: A total of forty-seven clinically and histopathologically diagnosed patients were scheduled for an hour-long interview, during which they provided informed consent and sociodemographic information. The psychological questionnaires applied were the revised Eysenck Personality Questionnaire and the clinical questionnaire for the diagnosis of the depressive syndrome. RESULTS: The patient's mean age was 66.5 years (SD ± 12.4) and the majority were diagnosed with basal cell carcinoma (70.2%). The frequency of anxious/depressive symptoms was 42.5%, with an increase in depression scores in the female gender (p < 0.001). Furthermore, a difference was found in the neuroticism dimension related to gender, with higher values in women (p = 0.002). Depressive symptomatologic portraits were correlated with the dimensions of neuroticism (p < 0.001, r = 0.705), psychoticism (p = 0.003, r = 0.422) and lying (p = 0.028, r = - 0.321). CONCLUSIONS: Our results support the hypothesis that personality dimensions are related to the presence of anxiety/depressive symptomatology in patients with skin cancer, especially in the female gender. Highlighting the need for future research that delves into the implications at the psychological level, the quality of life, and the biological mechanisms that link personality and depressive symptoms in the development and evolution of skin cancer.
RESUMO
ABSTRACT: Aims: To identify the frequency in changes of bone metabolism, including below the average value for age, osteopenia, and osteoporosis, in people living with HIV/AIDS (PLWHA) and to compare the frequency of factors associated with bone mineral density (BMD) and body composition between sex. Methods: This observational study assessed 106 PLWHA (65 male) recruited from the University Hospital of Ribeirão Preto Medical School from 2013 to 2014. BMD was measured using Dual Energy X-ray Absorptiometry (DXA). Standard deviation values for Z- and T-score proposed by the International Society for Clinical Densitometry were adopted to classify participants below the average value for age, osteopenia, and osteoporosis. Qui-square and Fischer's exact tests were employed to compare males and females based on their factors associated with BMD reduction. Results: Fifty-two (49%) PLWHA presented at least one diagnosis for below the average value for age, osteopenia, and osteoporosis, being 37 (57%) and 15 (37%) male and female, respec-tively. Frequency of alcohol consumption was higher in males (n=20; 30.8%) than females (n=05; 12.2%) (p=0.028).Conclusions: A high rate of PLWHA showed changes in bone metabolism, with a higher frequency in males. The fre-quency of alcohol consumption was higher in males, and it may partially explain the possible causes of the increased rates of bone metabolism changes observed in this group. This information may help develop strategies for reducing the frequency of diagnosis for below the average value for age, osteopenia, osteoporosis improving quality of life in PLWHA. (AU)
RESUMO: Objetivos: Identificar a frequência de alterações no metabolismo ósseo, incluindo valores abaixo do estimado para idade, osteopenia e osteoporose, em pessoas vivendo com HIV/Aids (PVHA) e comparar a frequência de fatores associados à redução da densidade mineral óssea (DMO) e composição corporal entre sexos. Métodos: Estudo observacional que ava-liou 106 PVHA (65 do sexo masculino) recrutadas do Hospital das Clínicas da Faculdade de Medicina de Ribeirão Preto da Universidade de São Paulo entre os anos 2013 e 2014. A DMO foi medida utilizando a Absorciometria Radiológica de Dupla Energia (DXA). Valores de desvio padrão Z- e T- scores propostos pela Sociedade Internacional para Densitometria Clí-nica foram adotados para classificar os participantes em abaixo do valor estimado para idade, osteopenia e osteoporose. Os testes do qui-quadrado e exato de Fischer foram empregados na comparação entre os sexos baseado em seus respec-tivos fatores associados à redução da densidade mineral óssea. Resultados: Cinquenta e dois (49%) PVHA apresentaram ao menos um diagnóstico para abaixo do valor estimado para idade, osteopenia e osteoporose, sendo 37 (57%) do sexo masculino e 15 (37%) feminino. A frequência de consumo de álcool foi maior no sexo masculino (n=20; 30,8%) compara-do ao feminino (n=5; 12,2%) (p=0,028). Conclusões: Uma alta taxa de PVHA apresentaram alterações no metabolismo ósseo, com maior frequência no sexo masculino. A frequência no consumo de álcool foi maior no sexo masculino, podendo explicar parcialmente as possíveis causas para taxa aumentada de alterações no metabolismo ósseo observada nesse grupo. Essa informação pode contribuir no desenvolvimento de estratégias para redução da frequência do diagnóstico para valores abaixo do estimado para idade, osteopenia e osteoporose, melhorando a qualidade de vida em PVHA

Resumen La otitis media crónica colesteatomatosa (OMCC) complicada es una condición inusual en la época actual. Clásicamente las complicaciones se han clasificado en extracraneales e intracraneales. Estas últimas suponen un alto riesgo para los pacientes debido a la alta morbimortalidad y las secuelas neurológicas asociadas. La atención médica oportuna y derivación a otorrinolaringología junto con las medidas preventivas en edad pediátrica han disminuido la incidencia de los colesteatomas y sus complicaciones. Se presenta a continuación el caso de una paciente de 50 años, atendida en el Hospital Guillermo Grant Benavente de Concepción (Chile) por cuadro de OMCC complicada con meningoencefalitis y vasculitis infecciosa sin consulta precoz por contexto de pandemia COVID-19. Se expone metodología diagnóstica y manejo terapéutico.
Abstract Complicated chronic cholesteatomatous media otitis (CCMO) is an unusual condition nowadays. Complications have traditionally been classified as extracranial and intracranial. The last one entails a higher risk for patients due to high morbi-mortality and neurological consequences associated. Suitable medical care and otorhinolaryngological attention among with preventive measures in pediatric age have decreased the incidence of cholesteatomas and their complications. The following, is the case of a 50-year-old patient treated for CCMO at Guillermo Grant Benavente Hospital in Concepcion (Chile) complicated due to meningoencephalitis and infectious vasculitis without early diagnose due to COVID-19 pandemic. Diagnostic methodology and therapeutic management are exposed.
RESUMO
One year after the first case reported by a new coronavirus (COVID-19), the evidence has shown a series of persistent signs and symptoms once the acute process has been overcome.Under the WHO's framework for health and disability, these impairments at cardiorespiratory, cognitive, and musculoskeletal body functions and structures lead, at least in the short and mid-term, to activity limitations and participation restriction. In this review, we discussed the main alterations generating disability and the challenges of implementing effective evaluation strategies in this disease. Along with their role in the health emergency, rehabilitation teams are challenged to design and deliver timely intervention strategies to reduce post-COVID-19 disability. (AU)

INTRODUCTION AND AIMS: More than 20% of healthcare-associated infections correspond to those at surgical sites, and there is a higher incidence of infections in colorectal surgery due to the associated bacterial load. Surgical wound protectors are designed to prevent contamination and mechanical trauma. Our aim was to demonstrate the usefulness of a circumferential wound retractor/protector for the prevention of surgical site infections (SSIs) in emergency colorectal surgery. METHODS: Forty-one patients that underwent emergency open surgery at a tertiary care hospital were randomized into 2 groups: 20 cases without the retractor (group A) and 21 cases with the retractor (group B). Subjects were assigned to a group in a 1:1 randomization allocation ratio. The chi-square and Fisher's exact tests were employed for the quantitative variables, and the statistical analysis was performed using the IBM Statistical Package for the Social Sciences software for Mac, version 16.0 (IBM SPSS Inc., Chicago, IL, USA). RESULTS: The SSI rate was 17%. Six group A patients developed SSI versus one group B patient. The use of a circumferential wound retractor/protector was statistically significant for the prevention of surgical wound infections, with a P=.031 and an OR of 8.5. In addition, preoperative blood glucose levels below 200mg/dl provided a 3.2-times higher protective effect, compared with glucose levels above 200mg/dl. CONCLUSIONS: In the present prospective randomized pilot study, the use of the circumferential wound retractor/protector significantly decreased the likelihood of SSI in emergency colorectal surgery.

BACKGROUND: Promising results have been reported with immune checkpoint inhibitors (ICI) in a small proportion of MPM patients. MMR deficiency (dMMR) has been well described in several malignancies and was approved as a biomarker for anti-PD-1 inhibitors. Next generation sequencing (NGS) data demonstrated that 2% of MPM harbor microsatellite instability. The aim of this study is to characterize MMR by immunohistochemistry (IHC) in a series of MPM including a subset of patients treated with immunotherapy. METHODS: Tumors of 159 MPM p diagnosed between 2002 and 2017 were reviewed. Formalin-fixed, paraffin-embedded tissue was stained for MLH1, MSH2, MSH6 and PMS2 and tumors were classified as dMMR (MMR protein expression negative) and MMR intact (all MMR proteins positively expressed). We retrospectively collected clinical outcomes under standard chemotherapy and experimental immunotherapy in the entire cohort. RESULTS: MMR protein expression was analyzed in 158 samples with enough tissue and was positive in all of the cases. Twenty two patients received ICI with anti-CTLA4 or anti-PD-1 blockade in clinical trials, 58% had a response or stable disease for more than 6 m, with median progression-free survival (PFS) of 5.7 m (2.1-26.1 m). The median overall survival (mOS) in all population was 15 months (m) (13.5-18.8 m). In a multivariable model factors associated to improved mOS were PS 0, neutrophil-lymphocyte ratio (NLR) < 5 and epithelioid histology (p < 0.001). CONCLUSIONS: In our series we were unable to identify any MPM patient with dMMR by IHC. Further studies are needed to elucidate potential predictive biomarkers of ICI benefit in MPM.
