ABSTRACT
INTRODUCTION: Telerehabilitation advanced significantly with the emergence of COVID-19 and the recommendation of limiting physiotherapist-patient contact time whenever practicable. The effectiveness of telerehabilitation on those who had a longer stay in hospital and on oxygen support following discharge is still under question. OBJECTIVES: To evaluate the effects after six weeks of pulmonary telerehabilitation on exercise tolerance, fatigue level, perceived exertion, symptoms of depression and quality of life in patients surviving COVID-19. MATERIALS AND METHODS: A quasi-experimental study was conducted on 25 post-COVID-19 patients following discharge in a home environment setting. The participants were advised to prepare equipment such as oxygen concentrator, B-type oxygen cylinder (backup), lengthy oxygen tubes, finger pulse oximeter, mini static pedal exerciser, incentive spirometry, weight cuffs or water bottles and sandbags. After six weeks of telerehabilitation, the patients underwent assessments including initial oxygen saturation (SPO2), heart rate, peak oxygen demand during exercise to maintain baseline SPO2, peak heart rate, maximum drop in SPO2, recovery time to baseline SPO2 measured with a pulse oximeter and stopwatch, peak perceived exertion using the Borg Dyspnea Scale, peak fatigue score using the visual analog scale (VASF), quality of life assessed with the SF-36 questionnaire, and mental health status evaluated with the Hamilton Depression Scale (HAMD). One-way repeated measure ANOVA and paired t-test were used. RESULTS: Significant improvements following the intervention on the initial SPO2 (F (2.12, 23.13) = 21.0, p< 0.05) and quality of life also showed significant improvement (mean difference =29.92, p< 0.05). CONCLUSION: Six weeks of comprehensive pulmonary telerehabilitation with simple equipment improved tolerance to exercise, fatigue, perceived exertion, symptoms of depression and quality of life for post-COVID-19 patients.
INTRODUÇÃO: A telereabilitação avançou significativamente com o surgimento da COVID-19 e a recomendação de limitar o tempo de contato entre fisioterapeutas e pacientes sempre que possível. A eficácia da telereabilitação em pacientes que permaneceram mais tempo no hospital e necessitaram de suporte de oxigênio após a alta ainda está em questão. OBJETIVO: Para avaliar os efeitos após seis semanas de telereabilitação pulmonar na tolerância ao exercício, nível de fadiga, percepção de esforço, sintomas de depressão e qualidade de vida em pacientes sobreviventes de COVID-19. MATERIAIS E MÉTODOS: Foi realizado um estudo quase-experimental com dezesseis pacientes pós-COVID-19 selecionados de um hospital multispecializado. Os participantes foram orientados a preparar equipamentos como concentrador de oxigênio, cilindro de oxigênio tipo B (reserva), tubos de oxigênio longos, oxímetro de pulso, exercitador de pedal estático, espirômetro incentivador, pesos de tornozelo ou garrafas d'água e sacos de areia. Após seis semanas de telereabilitação, os pacientes foram submetidos a avaliações, incluindo saturação inicial de oxigênio (SPO2), frequência cardíaca, demanda máxima de oxigênio durante o exercício para manter a SPO2 basal, frequência cardíaca máxima, queda máxima na SPO2, tempo de recuperação para SPO2 basal medido com um oxímetro de pulso e cronômetro, esforço percebido máximo usando a Escala de Dispneia de Borg, pontuação máxima de fadiga usando a escala analógica visual (VASF), qualidade de vida avaliada com o questionário SF-36 e estado de saúde mental avaliado com a Escala de Depressão de Hamilton (HAMD). RESULTADOS: Melhorias significativas após a intervenção foram observadas na SPO2 inicial (F (2,12, 23,13) = 21,0, p <0,05) e na frequência cardíaca (F (1,839, 20,23) = 43,73, p <0,05), demanda máxima de oxigênio durante o exercício para manter a SPO2 basal (F (1,487, 16,36) = 8,96, p <0,05), esforço percebido máximo (F (5, 55) = 112,51, p <0,05), pontuação máxima de fadiga (F (1,755, 19,30) = 67,44, p <0,05), frequência cardíaca máxima (F (1,798, 19,78) = 50,99, p <0,05), queda máxima na SPO2 (F (2,467, 27,14) = 41,46, p <0,05) e tempo máximo de recuperação para alcançar a SPO2 basal (F (5, 55) = 78,89, p <0,05). A análise de seis semanas pós-intervenção nos sintomas depressivos (diferença média = 11,25, p <0,05) e na qualidade de vida também mostrou melhoria significativa (diferença média = 29,92, p <0,05). CONCLUSÃO: Seis semanas de telereabilitação pulmonar abrangente com equipamentos simples melhoraram a tolerância ao exercício, a fadiga, a percepção de esforço, os sintomas de depressão e a qualidade de vida em pacientes pós-COVID-19.

High-flow nasal cannula oxygen therapy (HFNC) in palliative care is mentioned in several guidelines, however, the indication for this procedure has not been established yet. At our department, HFNC has increasingly been adopted for end-stage cancer patients when their dyspnea needs to be alleviated. This is a case report on three patients treated with this procedure at our department. Although they had severe dyspnea with respiratory failure, their daily activities, such as enjoying meals and conversation with their families, were improved with HFNC. It can be a treatment of choice to maintain and improve patients’ quality of life (QOL) in palliative setting, where benefits and risks should be considered for each patient.
ABSTRACT
Patients with chronic obstructive pulmonary disease have the disease phenomenon of fear of exercise because of dyspnea, which can accelerate the body degradation rate, weaken muscle strength, reverse increase dyspnea, and delay the recovery of the disease. As a result, this article examines the theoretical underpinnings and specific measures of dyspnea belief intervention programs for chronic obstructive pulmonary disease patients at home and abroad, summarizes the limitations of previous studies, and makes pertinent recommendations in an effort to serve as a guide for early patient prevention and the development of scientific and feasible intervention programs.
ABSTRACT
Objective:To study the clinical manifestations, genetic profiles and treatment of Kagami-Ogata syndrome (KOS).Methods:A neonate admitted to our hospital was genetically diagnosed of KOS from amniocentesis sampling. The phenotype, genotype and treatment of the neonate were analyzed. Multiple databases were searched using key words including "Kagami-Ogata syndrome", "14q32 microdeletion syndrome", "coat-hanger ribs", "paternal uniparental disomy (pUPD)(14) " from the inception of the databases to Jan. 23th 2023. The clinical features, genotype and treatment of patients from the literature were summarized.Results:The neonate in our hospital was born at 30 weeks gestational age with a birth weight of 2 035 g. Prenatal ultrasound indicated overgrowth, bilateral fetal renal pelvis dilatation (FRPD), dilatation of intestines in lower abdomen, clenched hands with overlapping fingers and polyhydramnios. After birth, the neonate showed progressively worsening respiratory distress, distinct facial features (small jaw, short neck, flat nasal bridge, upward-facing nostrils, small and malformed ears with auricular deformity and narrow external auditory canals), bell-shaped thorax, diastasis recti and abnormal posture (overlapping fingers, clenched fists), as well as feeding difficulties, recurrent fever and dependence of respiratory support. Whole exome sequencing (WES) revealed a 268.2Kb deletion (101034306_101302541) in 14q32.2 region on both the neonate and the mother and the father was otherwise normal. The prognosis was poor and the parents refused further treatment. The neonate died at one month of age after two days of palliative care. A total of 36 articles were identified in the literature review, including 78 KOS cases with complete clinical data (a total of 79 cases adding our case).The primary clinical manifestations included distinctive facial and thoracic abnormalities (79/79, 100%), polyhydramnios (71/75, 94.7%), feeding difficulties (55/63, 87.3%), abdominal wall defects (57/72, 79.2%), joint contractures (39/70, 55.7%) and dependence of respiratory support (29/56, 51.8%). Long-term follow-up revealed 86.8% (59/68) experienced physical, movement and intellectual development delay, 39.7% (25/63) died or gave up treatments within five years. Genetic testing showed pUPD in 44 cases (55.7%), maternal deletions in 23 cases (29.1%), epimutations in 8 cases (10.1%) and unreported variations in 4 cases (5.1%).Conclusions:KOS is a genetic imprinting disorder affecting multiple organs. Prenatal screening can detect abnormalities such as polyhydramnios. Specific clinical signs, radiological findings and 14q32 gene analysis are helpful for the diagnosis of the disease.
ABSTRACT
Objective:To study the predictive values of lung ultrasound (LUS) score and Downes score in selecting respiratory support strategies for newborns with dyspnea.Methods:From September 2021 to July 2022, newborns admitted to our hospital with dyspnea were selected and assigned into the non-invasive respiratory support (N) group, invasive respiratory support (I) group and control (C) group based on the respiratory support strategies on admission. LUS scores and Downes scores at 6, 24, and 48 h after birth were recorded. ROC curves were drawn to determine the predictive values of LUS and Downes scores for respiratory support strategies.Results:A total of 263 cases were enrolled, including 105 cases in N group, 56 cases in I group and 102 cases in C group. The differences of LUS and Downes scores between the three groups at the same timepoint were statistically significant with I group had the highest scores, N group second and C group lowest ( P<0.05). LUS and Downes scores within each group at different timepoints were significantly different ( P<0.05).In all three groups, LUS and Downes scores were decreased with longer duration of treatment. LUS score, Downes score and PaO 2/FiO 2 were positively correlated with each other ( P<0.05). The area under the curve (AUC) of LUS score and Downes score predicting non-invasive respiratory support within 6 h after birth were 0.900 (95% CI 0.861-0.940, P<0.05) and 0.889 (95% CI 0.847-0.931, P<0.05), respectively, with the same cutoff of 2.5. The AUC of the combination of LUS and Downes scores predicting non-invasive respiratory support was 0.944 (95% CI 0.915-0.973, P<0.05). The AUC of LUS score and Downes score predicting invasive respiratory support were 0.979 (95% CI 0.963-0.995, P<0.05) and 0.831 (95% CI 0.760-0.902, P<0.05), respectively, with the same cutoff of 5.5. The AUC of the combination of LUS and Downes scores predicting invasive respiratory support was 0.985 (95% CI 0.972-0.998, P<0.05). Conclusions:Both LUS score and Downes score have certain predictive values for respiratory support strategies in newborns with dyspnea.
ABSTRACT
Objective:To investigate the efficacy of an extracorporeal diaphragm pacemaker (EDP) combined with airway clearance technology (ACT) in the treatment of pulmonary infection in older adult patients with dementia and its impact on diaphragmatic mobility and thickness.Methods:A total of 60 patients with dementia and pulmonary infections who received treatment at The Second Hospital of Jinhua from June 2022 to February 2023 were included in this prospective study. These patients were randomly divided into an observation group and a control group, with 30 patients in each group. The control group received ACT treatment, while the observation group received EDP treatment on the basis of ACT treatment. Two groups were treated for 4 successive weeks. Efficacy was compared between the two groups. Before and after treatment, sputum color score, sputum quality score, diaphragmatic mobility, and diaphragmatic thickness were compared between the two groups.Results:The overall response rate in the observation group was 93.33% (28/30), which was significantly higher than 73.33% (22/30) in the control group ( Z = 2.08, P = 0.038). After treatment, the sputum color score, sputum quality score, and sputum volume in the observation group were (0.46 ± 0.12) points, (0.34 ± 0.10) points, and (8.47 ± 1.23) mL, respectively, which were significantly lower than (0.89 ± 0.17) points, (0.76 ± 0.18) points, and (13.25 ± 2.87) mL, respectively, in the control group ( t = 11.32, 11.17, 8.38, all P < 0.001). After treatment, the diaphragmatic mobility and thickness in the observation group were (13.52 ± 0.51) mm and (0.52 ± 0.06) mm, respectively, which were significantly greater than (12.76 ± 0.41) mm and (0.44 ± 0.04) mm, respectively, in the control group ( t = -6.36, -6.08, both P < 0.001). Conclusion:The combined application of EDP and ACT shows a significant therapeutic effect on patients with dementia and pulmonary infection, effectively improving their pulmonary function, increasing the mobility and thickness of the diaphragm, and alleviating difficulties in breathing.
ABSTRACT
Objective To compare the accuracy of bedside lung ultrasound in emergency(BLUE)and combined cardiac-lung and additional ultrasound(CLAUS)for diagnosing the causes of acute dyspnea.Methods Totally 1 016 patients with acute dyspnea were retrospectively enrolled and divided into cardiogenic pulmonary edema group(n=268),pneumonia group(n=574),pneumothorax group(n=33),pulmonary embolism group(n=67)and CAD(chronic obstructive pulmonary disease/asthma/diaphragmatic dysfunction)group(n=74)according to the causes of acute dyspnea.The findings of CLAUS protocol were compared among groups,and the accuracy of BLUE and CLAUS protocol for diagnosing the causes of acute dyspnea were also compared.Results CLAUS showed that B-B and B-C were the most common modes in cardiogenic pulmonary edema group,while A-B/A-C/B-A/B-B/B-C/C-C modes were common in pneumonia group,and A-A mode was the most common in pneumothorax group,pulmonary embolism group and CAD group.Significant differences of the manifestations of pulmonary ultrasound,pleural feature of anterior chest wall,left/right cardiac insufficiency and abnormal inferior vena cava diameter were found among groups(all P<0.05).The accuracy of BLUE and CLAUS protocol for diagnosing the causes of acute dyspnea was 86.91%(883/1 016)and 94.49%(960/1 016),respectively,the latter was higher than the former(χ2=34.587,P<0.05).Conclusion CLAUS protocol could be used to effectively diagnose the causes of acute dyspnea,with higher accuracy than BLUE protocol.
ABSTRACT
ABSTRACT Objectives: To describe persistent symptoms and lung function in mild cases of COVID-19 six months after infection. Methods: Data collection was performed through a semi-structured questionnaire containing information on the participants' demographic and anthropometric data, the disease in the acute phase, and persistent symptoms six months after COVID-19 using spirometry and manovacuometry. Results: A total of 136 participants were evaluated, of whom 64% were male, with a mean age of 38.17 ± 14.08 years and a body mass index (BMI) of 29.71 ± 17.48 kg/m2. The main persistent symptoms reported were dyspnea on exertion (39.7%), memory loss (38.2%), and anxiety (48.5%). Considering lung function, the participants reached 88.87 ± 17.20% of the predicted forced vital capacity (FVC), 86.03 ± 22.01% of the forced expiratory volume in one second (FEV1), and 62.71 ± 25.04% of peak expiratory flow (PEF). Upon manovacuometry, 97.41 ± 34.67% of the predicted inspiratory force (Pimax) and 66.86 ± 22.97% of the predicted expiratory force (Pemax) were observed. Conclusions: Six months after COVID-19 infection, a reduction in PEF and MEP was observed. Among the most commonly reported persistent symptoms were fatigue, tiredness with the slightest exertion, anxiety and depression, memory loss, and deficits in concentration.

ABSTRACT
Abstract Platypnea-orthodeoxia syndrome (POS) is a rare condition of positional hypoxemia and dyspnea. The following is a case of hypoxemia for no obvious reason in the perioperative scenario. A 70-year-old male patient was submitted to a radical prostatectomy. On several occasions after anesthetic induction, peripheral oxygen saturation decreased without any understandable cause. In the postanesthesia care unit, severe hypoxemia occurred in the upright position, oddly correcting with recumbency. An echocardiography showed a right-to-left intracardiac shunt through a patent foramen ovale with no pulmonary hypertension, establishing POS. Achieving this diagnosis required a broad workup with a high degree of suspicion.
ABSTRACT
Abstract Introduction With the advances in critical care, the incidence of post intubation tracheal stenosis is increasing. Tracheal resection and anastomosis have been the gold standard for the management of grades III and IV stenosis. Scientific evidence from the literature on the determining factors and outcomes of surgery is not well described. Objective This study was aimed at determining the influence of tracheostoma site on the surgical outcomes and postoperative quality of life of patients undergoing tracheal resection anastomosis. Methods Thirteen patients who underwent tracheal resection and anastomosis during a period of 3 years were followed up prospectively for 3 months to determine the degree of improvement in their quality of life postsurgery by comparing the pre and postoperative validated Tamil/vernacular version of RAND SF-36 scores and Medical Research Council (MRC) dyspnea score. Results As per preoperative computed tomography (CT), the mean length of stenosis was found to be 1.5 cm while the mean length of trachea resected was 4.75 cm. We achieved a decannulation rate of 61.53%. There was an estimated loss of 3.20 +/- 1.90 cm of normal trachea from the lower border of the stenosis until the lower border of the stoma that was lost during resection. Analysis of SF-36 and MRC dyspnea scores revealed significant improvement in the domains of physical function postoperatively in comparison with the preoperative scores (p < 0.05). Conclusion Diligent placement of tracheostomy in an emergency setting with respect to the stenotic segment plays a pivotal role in minimizing the length of the resected segment of normal trachea.
ABSTRACT
ABSTRACT Objective: To evaluate symptoms, lung function, and quality of life of a cohort of patients hospitalized for severe COVID-19 12 months after hospital admission. Methods: This was a cross-sectional study. We included severe COVID-19 survivors hospitalized in one of three tertiary referral hospitals for COVID-19 in the city of Belo Horizonte, Brazil. Participants were submitted to lung function and six-minute walk tests and completed the EQ-5D-3L questionnaire. Results: The whole sample comprised 189 COVID-19 survivors (mean age = 59.6 ± 13.4 years) who had been admitted to a ward only (n = 96; 50.8%) or to an ICU (n = 93; 49.2%). At 12 months of follow-up, 43% of patients presented with dyspnea, 27% of whom had a restrictive ventilatory disorder and 18% of whom presented with impaired DLCO. There were no significant differences in FVC, FEV1, and TLC between the survivors with or without dyspnea. However, those who still had dyspnea had significantly more impaired DLCO (14.9% vs. 22.4%; p < 0.020) and poorer quality of life. Conclusions: After one year, survivors of severe COVID-19 in a middle-income country still present with high symptom burden, restrictive ventilatory changes, and loss of quality of life. Ongoing follow-up is needed to characterize long COVID-19 and identify strategies to mitigate its consequences.
ABSTRACT
Introducción: La enfermedad pulmonar intersticial difusa no soporta el ejercicio, debido a la sensación de disnea y fatiga durante el esfuerzo de baja intensidad. La recuperación de la frecuencia cardíaca se relaciona con el desempeño en el test de caminata de los seis minutos. Objetivo: Determinar las diferencias sociodemográficas de la función y la capacidad pulmonar en pacientes con enfermedad intersticial difusa, a partir de la recuperación de la frecuencia cardíaca durante el test de caminata de los seis minutos. Métodos: Se realizó un estudio descriptivo de corte transversal. Se calculó la recuperación de la frecuencia cardíaca a partir de la diferencia entre el final del test y los cinco minutos de la prueba. Se conformaron dos grupos de comparación, anormal versus normal, en variables sociodemográficas de la función pulmonar y la capacidad funcional. Resultados: Se vincularon 38 pacientes en el grupo normal y en el anormal 26. En el primero predominaron la edad de 62,26 ± 15,82 y los hombres (52,6 %); mientras que en el grupo anormal los años promediaron entre 58,77 ± 13,23 y sobresalieron las mujeres (61,5 %). Se presentó un valor p < 0,05 del grupo recuperación de la frecuencia anormal en la distancia recorrida, disnea y fatiga al final, un minuto y a los cinco minutos de culminar el test. Conclusiones: Los pacientes con enfermedad pulmonar intersticial difusa con una recuperación de la frecuencia cardíaca anormal presentaron peores resultados en la distancia recorrida, volumen de oxígeno, los equivalentes metabólicos, disnea y fatiga de los miembros inferiores.
Introduction: Diffuse interstitial lung disease does not tolerate exercise, due to the sensation of dyspnea and fatigue during low-intensity exertion. Heart rate recovery is related to performance in the six-minute walk test. Objective: To determine sociodemographic differences in lung function and capacity in patients with diffuse interstitial lung disease, based on heart rate recovery during the 6-minute walk test. Methods: A descriptive cross-sectional study was performed. Heart rate recovery was calculated from the difference between the end of the test and the five minutes of the test. Two comparison groups were formed, abnormal versus normal, in sociodemographic variables of pulmonary function and functional capacity. Results: 38 patients were included in the normal group and 26 in the abnormal group. In the normal group, age was 62.26 ± 15.82 and men were predominant (52.6 %); while in the abnormal group, age averaged 58.77 ± 13.23 and women were predominant (61.5 %). A p-value < 0.05 of the abnormal frequency recovery group was presented in the distance run, dyspnea at the end, fatigue at the end, 1 minute and at 5 minutes after the culmination of the test. Conclusions: Patients with diffuse interstitial lung disease with abnormal heart rate recovery had worse results in distance run, oxygen volume, metabolic equivalents, dyspnea and lower limb fatigue.
ABSTRACT
Este artículo está dedicado al análisis detallado de los mecanismos de disnea. Se tratarán el control químico de la respiración, los reflejos neurales, la mecánica respiratoria, el costo de oxígeno para respirar y la inadecuación entre tensión y longitud de la fibra muscular. En general, las diferentes explicaciones estuvieron asociadas al desarrollo de aparatos y metodologías de estudio de los laboratorios pulmonares. Todas las teorías tuvieron defensores y detractores e, interesantemente, con el desarrollo de sofisticadas técnicas neurofisiológicas y de imágenes funcionales ha sido posible jerarquizar cada uno de los mecanismos. Todas han sobrevivido al paso del tiempo y ninguna puede explicar de manera unicista la disnea en todas las situaciones clínicas, lo cual habla de la naturaleza compleja y multifactorial del fenómeno.
This article is devoted to a detailed analysis of the mechanisms of dyspnea. Chemical control of respiration, neural reflexes, respiratory mechanics, the cost of oxygen to breathe, and the mismatch between tension and muscle fiber length will be discussed. In general, the different explanations were associated with the development of apparatus and study methodologies in pulmonary laboratories. All the theories had defenders and detractors and, interestingly, with the development of sophisticated neurophysiological techniques and functional imaging it has been possible to prioritize each of the mecha nisms. All have survived the passage of time and none can explain dyspnea in all clinical situations, which speaks of the complex and multifactorial nature of the phenomenon.

Objective: Evaluate the spirometry pattern of patients who persisted with respiratory symptoms after infection with SARS-Cov-2. Methods: Cross-sectional, observational, retrospective study in a single center, approved by the local Ethics Committee (registration number: 5,120,720). Patients who underwent spirometry due to Post-Covid Syndrome were evaluated to analyze the spirometric pattern presented. The following were collected: exam identification data, sex, age, symptom time, the need for mechanical ventilation, and quality of spirometry, in addition to the following exam parameters: FVC, FEV1, FEV1/FVC, FEV 25-75/FVC, and FEV 75, evaluating the Lower Limit of Normality, pre-bronchodilator and post-bronchodilator values. Results: Data from 72 patients were collected. Of these, 55.5% of patients had spirometry results within normal limits. The most frequent respiratory alteration was obstructive respiratory disorder, present in 29.2% of the patients. Conclusions: The presence of dyspnea in patients with normal spirometry may indicate further evaluation of lung function and other etiologies for dyspnea (AU).

Este artículo es el primero de una serie dedicada a ese extraño fenómeno de la vida atrapado a medio camino entre lo consciente y lo inconsciente: la disnea. El artículo proporciona información sobre las definiciones a lo largo del tiempo y presenta la evolución de las ideas que hicieron a la comprensión de sus mecanismos. La relevancia de cada uno de ellos debe evaluarse en el contexto de cada situación clínica y fisiopatológica específica. La experiencia de la disnea comienza a ser vista como un fenómeno multidimensional que debe estar centrado en lo que percibe el paciente. Considerando la complejidad de la experiencia y su multidimensión, es posible que se desarrollen nuevas opciones terapéuticas en tiempos venideros(AU)

The article provides information on the definitions over time and presents the evolution of the ideas that led to understanding its mechanisms. The relevance of each of these mechanisms must be evaluated in the context of each specific clinical and pathophysiological situation. The experience of dyspnea begins to be seen as a multidimensional phenomenon that must be centred on what the patient perceives.

Background: Sexual life of women with chronic obstructive pulmonary disease (COPD) can be affected by breathing difficulties, a decrease in functional status, depressive mood and fatigue. Objetive: To evaluate the sexual dysfunction in female COPD patients and the possible explanatory mechanisms or correlations between these conditions. Methods: The study included 70 female patients with COPD aged between 36-65 and 70 age-matched controls. All the subjects completed questionnaires for the Female Sexual Functional Index (FSFI), BECK depression inventory and, spirometry. Results: Statistically significant sexual dysfunction was noted in COPD patients compared to the non-COPD group (p0.005). In linear regression analysis determining depression, no statistically significant factor was found among age, number of comorbidities, and FEV1/ forced vital capacity (FVC) % predicted (p>0.05). In multivariable analysis, only fatigue during intercourse was found to be a statistically significant factor in predicting sexual dysfunction among factors like age, presence of comorbidities, duration of the disease, smoking status, FEV1%, m MRCpoints, 6-minutes walk test, BECK depression scores (p=0.008). Conclusion: Sexual dysfunction is reported in many COPD females and seems to be related not to spirometric measures or exercise capacity but to fatigue. Depression is also a common comorbidity, of which both disorders are often neglected.
Antecedentes: La vida sexual en mujeres con enfermedad pulmonar obstructiva crónica (EPOC) es afectada por dificultades respiratorias, disminución del estado funcional, estado de ánimo depresivo y fatiga. Objetive: Evaluar la disfunción sexual en mujeres con EPOC y posibles mecanismos explicativos de esas dos condiciones Métodos: Participaron 70 pacientes mujeres con EPOC, rango edad 36-65 años y 70 controles emparejados por edad. Todos los sujetos respondieron un cuestionario para el índice funcional sexual femenino e inventario de depresión de BECK, mas una espirometría. Resultados: Se observó disfunción sexual significativa en las pacientes con EPOC comparado con el grupo sin EPOC. Las puntuaciones del inventario de depresión BECK fueron significativamente inferiores a las del grupo control. No hubo correlación entre las puntuaciones del FSFI y la depresión BECK con las características de las "mujeres" (r=-0.055). No se encontraron diferencias significativas en edad, FEV1% y antecedentes de exacerbación del año anterior según la gravedad de la depresión. En la regresión lineal para determinar la depresión, no hubo ningún factor estadísticamente significativo entre edad, número de comorbilidades y FEV1/FVC% predicho. En el multivariado, sólo la fatiga durante el coito resultó ser un factor significativo para predecir la disfunción sexual entre factores como edad, presencia de comorbilidades, duración de la enfermedad, hábito tabáquico, FEV1%, m MRCpoints, prueba de la marcha de 6 minutos y puntuaciones de depresión de BECK. Conclusiones: La disfunción sexual parece no estar relacionada con las medidas espirométricas o la capacidad de ejercicio, pero si con la fatiga. La depresión es una comorbilidad frecuente, de la que a menudo se descuidan ambos trastornos.

Introducción: El compromiso respiratorio en la enfermedad de Pompe es una de sus manifestaciones más frecuentes, tiene un impacto negativo en la calidad de vida y facilita la aparición de múltiples complicaciones. Se puede presentar como parte evolutiva de la enfermedad o incluso ser el síntoma inicial de la patología. Contenidos: La presentación clínica del compromiso respiratorio en la enfermedad de Pompe se caracteriza por disnea, ortopnea, cefalea y tos, y sus cambios paraclínicos incluyen hipercapnia, policitemia, elevación del índice de apnea/hipopnea, así como disminución de la capacidad vital y de las presiones inspiratoria y espiratorias máximas. El compromiso respiratorio es causado principalmente por disfunción muscular (especialmente el diafragma) y alteración de la regulación del sistema nervioso central. Conclusiones: Es fundamental la valoración acuciosa inicial de los patrones respiratorios y por supuesto su seguimiento, el cual dependerá del tipo de progresión de la disfunción respiratoria (rápida o lenta) o del requerimiento específico para cada paciente (ventilación no invasiva o invasiva).
Introduction: Respiratory compromise in Pompe disease is one of the most frequent manifestations, which has a negative impact on quality of life and leads to multiple complications. This can occur as an evolutionary part of the disease, or even be the initial symptom of the pathology. Contents: Its clinical presentation is characterized by dyspnea, orthopnea, headache, and cough, and its paraclinical changes include hypercapnia, polycythemia, elevated apnea/hypopnea index, decreased vital capacity, and decreased maximum inspiratory and expiratory pressures. Respiratory compromise is caused mainly by muscular dysfunction (especially the diaphragm) and alteration of regulation of the central nervous system. Conclusions: An initial careful assessment of respiratory patterns is essential, and of course their follow-up, that will depend of the type of progression of respiratory dysfunction (rapid or slow) or the specific requirement for each patient (non-invasive or invasive ventilation).

Introducción: La COVID-19 genera afectación durante el proceso de la enfermedad en el aparato respiratorio y cardiovascular; sin embargo, se desconoce si esta afectación desaparece con la resolución del proceso inflamatorio o se mantienen en forma de secuela con el de cursar del tiempo. Objetivo: Analizar la capacidad funcional cardiorrespiratoria en pacientes entre 30 y 60 años post COVID-19. Métodos: Se realizó una investigación básica, no experimental, descriptiva y transversal que incluyó 328 pacientes, de los cuales 178 formaron parte de la muestra. Se analizaron características generales, la capacidad funcional respiratoria y cardiovascular. Resultados: Promedio de edad de 53,48 años con predominio de pacientes femeninas (55,62 %). El 33,15 % de los pacientes refirió una comorbilidad asociada. El 15,73 % de los pacientes presentaba bradicardia y el 8,99 % taquicardia. En el 42,70 % de los casos se identificó enfermedad hipertensiva. Las manifestaciones respiratorias estuvieron dadas por la presencia de disnea y porcentaje elevado de pacientes con taquipnea y trastornos de la saturación de oxígeno. Conclusiones: Después de transcurridos 6 meses de la presencia de COVID-19 un elevado porcentaje de pacientes presentaban manifestaciones cardiorrespiratorias que afectaban la capacidad funcional de ambos aparatos.
Introduction: COVID-19 affects the respiratory and cardiovascular systems during the disease process; however, it is unknown if this affectation disappears with the resolution of the inflammatory process or if it remains in the form of a sequel over time. Objective: To analyze the cardiorespiratory functional capacity in patients between 30 and 60 years old post COVID-19. Methods: A basic, non-experimental, descriptive and cross-sectional investigation was carried out that included 328 patients, of which 178 were part of the sample. General characteristics, respiratory and cardiovascular functional capacity were analyzed. Results: Average age of 53,48 years with a predominance of female patients (55.62 %). 33.15 % of the patients reported an associated comorbidity. 15.73 % of the patients presented bradycardia and 8.99 % tachycardia. Hypertensive disease was identified in 42.70 % of the cases. The respiratory manifestations were given by the presence of dyspnea and a high percentage of patients with tachypnea and oxygen saturation disorders. Conclusions: After 6 months of the presence of COVID-19, a high percentage of patients presented cardiorespiratory manifestations that affected the functional capacity of both devices.
ABSTRACT
El enfrentamiento de estridor en el Servicio de Urgencias puede ser un desafío para el clínico. La mayoría de los pacientes responderán a medidas estándar de anafilaxia, no obstante, ante pacientes refractarios a tratamiento se deben sospechar otras patologías. Presentamos el caso clínico de una paciente refractaria a manejo de anafilaxia. Se realiza videolaringoscopía que identifica quiste de vallécula y se maneja mediante protección de vía aérea con intubación orotraqueal. Se decide escisión quirúrgica, en la cual se identifica estenosis subglótica que requiere instalación de traqueostomía. La paciente evoluciona favorablemente y es dada de alta.
Coping with stridor in the Emergency Department can challenge the clinician. Most patients respond to standard anaphylaxis measures. The clinician should suspect other differential diagnoses when patients are refractory to treatment. We present the clinical case of a patient refractory to standard anaphylaxis management. A video laryngoscopy was performed, identifying a vallecula cyst. We secured the airway through orotracheal intubation. The surgical team of our hospital performed a surgical excision of the cyst and identified subglottic stenosis, which required the installation of a tracheostomy. The patient evolved favorably in the postoperative period and was discharged.
ABSTRACT
La tuberculosis miocárdica es una localización infrecuente que, en general, se caracteriza por cuadros clínicos silentes. Su diagnóstico se basa en la alta sospecha clínica y hallazgos inespecíficos en las imágenes cardíacas, pero la histopatología continúa siendo el estándar de oro para establecer el diagnóstico. La terapia antituberculosa ha sido exitosa, presentando mejoría radiológica y clínica en la mayoría de los casos. Presentamos el caso de una infección miocárdica por Mycobacterium tuberculosis en un hombre de 34 años que consultó por un cuadro de disnea de varias semanas de evolución. Se pesquisó un derrame pleural derecho y pericárdico grave, sin signos de taponamiento cardíaco. La RPC para M. tuberculosis en líquido pleural resultó positiva. El estudio histológico de pericardio y miocardio evidenció una pericarditis crónica y una inflamación granulomatosa, no necrosante, con células gigantes multinucleadas en el tejido miocárdico. Se estableció el diagnóstico de tuberculosis pleural, pericárdica y miocárdica y se inició tratamiento antituberculoso, presentando una mejoría clínica significativa.
Myocardial tuberculosis is a rare location that is generally characterized by silent clinical pictures. Diagnosis is based on high clinical suspicion and some nonspecific findings on cardiac imaging, but histological findings remain the gold standard. Treatment with standard antitubercular drugs llave been successful, presenting radiological and clinical improvement in most cases. We report a case of myocardial infection by Mycobacterium tuberculosis in a 34-year-old man, who presented with several weeks of dyspnea and evidence of right pleural effusion and severe pericardial effusion, without signs of cardiac tamponade. PCR for M. tuberculosis was positive in pleural fluid. The histologic study of pericardium and myocardium showed myocardial fibers with non-necrotizing granulomatous inflammation with multinucleated giant cells. Due to all the above, a diagnosis of pleural and myocardial tuberculosis was made, and tuberculosis treatment was started with significant clinical improvement.
