Evaluación del control del Asma en República Dominicana: una perspectiva clínica / Evaluation of Asthma Control in the Dominican Republic: a Clinical Perspective

Introducción: El asma es una patología respiratoria caracterizada por inflamación cró-nica y reversible de las vías aéreas. Esta se asocia con factores de riesgo modificables y no modificables que influyen sobre su control y exacerbaciones. En países como Puer-to Rico y Cuba, la prevalencia del asma es significativamente mayor a la global (22,8%, 23% y 6,6%, respectivamente).

Introduction: Asthma is a respiratory pathology characterized by chronic and reversible airway inflammation. It is associated with modifiable and non-modifiable risk factors that influence its control and exacerbations. In countries such as Puerto Rico (22.8 %) and Cuba (23 %), the prevalence of asthma is significantly higher than the global prevalence (6.6 %).

Periprosthetic gout flare after total knee arthroplasty: A misdiagnostic case report / 北京大学学报(医学版)

Periprosthetic gout flare is a rare arthritic condition after total knee arthroplasty, but the symptoms of gout may have often been mistaken as acute periprosthetic infection given their similarity. Misdiagnosis as periprosthetic infection can lead to unnecessary surgery, long-term dependence on anti-biotics, and even malfunction of the involved knee joint. Here, we report a case study of a patient with immunodeficiency condition of long-term oral glucocorticoid and diabetes mellitus, who had undergone a knee replacement 8 weeks before. The initial symptoms of fever and joint pain together with the dysfunction of her right knee with elevated inflammatory markers, such as increased serum leukocytes, erythrocyte sedimentation rate, C-reactive protein, and synovial cell counts led to a diagnosis of acute periprosthetic infection. Arthrocentesis and bacterial culture were performed preoperatively. According to the current Musculoskeletal Infection Society (MSIS) criteria for diagnosis of periprosthetic infection, the case was classified as periprosthetic infection and a prosthesis retained debridement surgery was performed. However we got negative culture results in all the pre-operative and intro-operative samples. The symptoms as well as the laboratory inflammatory markers improved shortly after the debridement surgery until the 11th day when all the similar systemic and local symptoms recurred. With a remedial crystal analysis of synovial fluid from the patient, gouty flare was found to be the cause of acute arthritis finally. Accor-dingly, after anti-gout medications were administrated, the symptoms associated with acute arthritis gra- dually subsided, and there was no recurrence during a 24-month follow-up. This article described the cli-nical manifestation, diagnosis and differential diagnosis, treatment of a case of periprosthetic gout. Although relatively rare, gout should be considered as a differential diagnosis in suspected periprosthetic infection. Current criteria for periprosthetic infection can not exclude the diagnosis of periprosthetic gout flare, it is therefore imperative that the analysis of joint aspirate for crystals be conducted to determine the correct course of treatment, or unnecessary surgical procedure may be performed in periprosthetic gout case.

Estimation of the predictive effect of body mass index-percentile on skeletal maturation in a Nigerian population

To determine the predicting the effect of BMI-index percentile on the skeletal maturation of Nigerian children. Design: A prospective cross-sectional study. Setting: This study was conducted in a tertiary health care facility in North-Central Nigeria. Participants: Children between the ages of 5-17 years consisting of 44 males and 30 females that presented in the Child Dental clinic over a period of eight months were recruited for the study. Main outcome measured: Skeletal maturation was assessed using the middle phalanx of the third finger (MP3) while the standard WHO growth chart specific for age (2-20 years) and gender was used for grading BMI-percentile. The unpaired t-test was used to compare mean chronological age of the stages of MP3 according to gender. Multinomial logistic regression used to determine the predictive effect of age, gender and BMI percentile on pubertal growth spurt. Results: The BMI-percentile had weak correlation with the pubertal growth spurt (r=0.089, p=0.448). Gender (p=0.004) and chronological age had significant (p<0.001) predictive effect on the skeletal maturation. A one-percentile increase in the BMI-percentile decreases the likelihood of healthy children to be in the peak-pubertal by 1.504 when compared to obese children (p=0.305). Conclusions: This study showed that BMI-percentile is a weak predictor of skeletal maturation. However, obese children had a tendency towards advanced skeletal maturation than healthy participants. It is therefore suggested that orthodontists should consider early implementation of jaw modification treatments among obese children.

Fatores relacionados a múltiplas consultas de urgência e internação hospitalar devido à descompensação asmática em pacientes adultos / Factors related to multiple urgent consultations and hospitalization due to asthmatic decompensation in adult patients

Introdução: A asma é caracterizada por inflamação crônica das vias aéreas. Exacerbações são episódios de aumento de sintomas e deterioração da função pulmonar. Objetivo: Avaliar fatores relacionados a múltiplas idas à emergência e internação por exacerbação asmática. Métodos: Estudo transversal, retrospectivo e analítico. Analisamos prontuários de pacientes adultos que foram atendidos no pronto-socorro (PS) por duas ou mais vezes em 2019 e receberam diagnóstico de asma. Os pacientes foram divididos em grupos de acordo com o número de idas a emergência: 2 ou 3 vezes (grupo A), e mais de 4 vezes (grupo B). Posteriormente foram divididos nos grupos Internação Hospitalar (IH) e Não Internação Hospitalar (NIH). Resultados: Gênero feminino correspondeu a 74% dos pacientes, e infecção bacteriana foi o fator desencadeante mais relatado. No grupo A, 67% não fazia acompanhamento ambulatorial regular; e no grupo B, 75% não o fazia. No grupo A, 37% usava corticoide inalatório em dose alta versus 75% do grupo B. Corticoide inalatório em dose alta foi associado ao risco de quatro ou mais idas ao PS. Foram internados 19% dos pacientes (grupo IH). Procuraram quatro vezes ou mais o PS por asma 29% dos pacientes IH, e 7% dos NIH. Usavam corticoide inalatório em altas doses 86% dos pacientes IH, e 31% dos NIH. No grupo IH, 50% apresentava distúrbio ventilatório obstrutivo moderado, contra apenas 8% do NIH. Múltiplas idas ao PS, CI dose alta e distúrbio ventilatório moderado foram associados à internação hospitalar. Conclusão: Múltiplas idas ao PS por asma em pacientes adultos tiveram correlação com a falta de acompanhamento ambulatorial, infecções bacterianas e uso de medicações em altas doses. Foram fatores de risco para a internação hospitalar: quatro ou mais idas ao PS e asma grave.

Introduction: Asthma is characterized by chronic inflammation of the airways. Exacerbations are episodes of increased symptoms and deterioration of lung function. Objective: To evaluate factors related to multiple visits to the emergency room (ER) and hospitalization due to asthmatic exacerbation. Methods: In this cross-sectional, retrospective, and analytical study, we analyzed medical records of adult patients who were seen at the ER at least twice in 2019 and were diagnosed with asthma. The patients were divided into groups according to the number of emergency visits: 2 or 3 times (group A) and 4 times or over (group B). Subsequently, they were divided into groups hospitalization (H) and no hospitalization (NH). Results: Seventy-four percent of patients were female, and bacterial infection was the most reported triggering factor. Lack of regular outpatient follow-up was found in 67% of patients in group A and 75% in group B. In group A, 37% used high-dose inhaled corticosteroids versus 75% in group B. High-dose inhaled corticosteroids were associated with a risk of 4 visits or over to the ER. Nineteen percent of patients were hospitalized (group H). Twenty-nine percent of group H and 7% of group NH sought the ER four times or over for asthma. Eightysix percent of group H and 31% of group NH used high-dose inhaled corticosteroids. In group H, 50% had moderate obstructive ventilatory impairment, compared to only 8% in group NH. Multiple visits to the ER, high-dose inhaled corticosteroids, and moderate ventilatory impairment were associated with hospitalization. Conclusion: Multiple visits to the ER for asthma in adult patients correlated with lack of outpatient follow-up, bacterial infections, and use of high-dose medications. Four visits or over to the ER and severe asthma were found to be risk factors for hospitalization.

Adherencia terapéutica en hipertensos con incremento matutino de la presión arterial / Therapeutic adherence in hypertensive patients with morning hypertension

Introducción: El incremento matutino de la presión arterial detectado por monitoreo ambulatorio se asocia a daño de órgano blanco y a una mayor incidencia de eventos cardiovasculares. Objetivo: Determinar la adherencia terapéutica en hipertensos con incremento matutino de la presión arterial. Métodos: Se realizó un estudio transversal en 195 pacientes hipertensos ingresados en el servicio de medicina interna del Hospital Universitario Calixto García en el año 2018. Estos mostraron incremento matutino de la presión arterial y se valoró la adherencia terapéutica mediante el test de cumplimiento autocomunicado de Morisky-Green-Levine. Las variables identificadas como predictores relevantes de no adherencia fueron introducidas en un modelo multivariado de regresión logística. Resultados: 63,6 por ciento de los pacientes con incremento matutino de la presión fueron no adherentes, predominaron los pacientes del sexo masculino, 71,6 por ciento. El 84,0 por ciento (p=0,00) de los no adherentes ingerían de 3 a 4 fármacos antihipertensivos, 90,2 por ciento (p=0,00) tomaban 3 o más dosis. 50,5 por ciento de los pacientes tenía un diagnóstico de más de 5 años. Conclusiones: Los pacientes con incremento matutino de presión arterial se caracterizaron por ser no adherentes a la terapéutica antihipertensiva(AU)

Introduction: The morning hypertension detected by ambulatory monitoring is associated with target organ damage and a higher incidence of cardiovascular events. Objective: To determine the therapeutic adherence in hypertensive patients with a morning hypertension. Methods: A cross-sectional study was carried out in 195 hypertensive patients admitted to the internal medicine service at Calixto García University Hospital in 2018. They showed a morning increase of blood pressure and therapeutic adherence was assessed using the self-reported compliance test by Morisky-Green-Levine. The variables identified as relevant predictors of non-adherence were entered in a multivariate logistic regression model. Results: 63.6 percent of the patients with morning hypertension were non-adherent. Male patients predominated. 71.6 percent 84.0 percent (p = 0.00) of the non-adherents had 3 to 4 antihypertensive drugs, 90.2 percent(p = 0.00) took 3 or more doses. 50.5 percent of the patients were diagnosed for more than 5 years. Conclusions: Patients with morning hypertension were described as non-adherent to antihypertensive therapy(AU)

Tempo entre o início dos sintomas e a hospitalização / Time between the onset of symptoms and hospitalization

Apresenta a compilação de estudos presentes na literatura internacional, apontando a variação nos intervalos de tempo relatados e no tempo médio desde o início dos sintomas até o momento de admissão hospitalar; concluindo que a diferença pode estar relacionada ao desenho metodológico, assim como ao reconhecimento e atenção aos sintomas à medida que a infecção pelo novo coronavírus (COVID-19) torna-se mais conhecida

It presents a compilation of studies present in the international literature, variation in reported time intervals and in the mean time from onset of symptoms to hospital admission; concluding that the difference may be related to the methodological design, as well as the recognition and attention to symptoms as the new coronavirus infection (COVID-19) becomes better known

Risk factors and diagnostic value for ultrasound-detected tendon monosodium urate crystal deposition in patients with gout / 北京大学学报(医学版)

OBJECTIVE@#To evaluate frequency and patterns, risk factors of MSU (monosodium urate) crystal deposition at lower extremity tendon by ultrasonography in gout patients, and to explore diagnostic value by ultrasonography.@*METHODS@#Patients diagnosed with gout and age matched healthy controls had ultrasound scanning of both feet and knees including joints and tendons (achilles, quadriceps, and patellar tendon). Readers who scored the ultrasound scans for MSU crystal deposition were blinded to the patients' clinical diagnoses. Clinical characteristics were compared between positive and negative crystal deposition groups by US, and risk factors of MSU deposition in tendons were analyzed. Diagnostic values of MSU deposition were evaluated by ultrasonography according with positive MSU crystal in synovial fluid or tophi by polarized microscopy.@*RESULTS@#Eighty patients and eighty healthy controls were included. Thity-three patients (47.5%) had tophi by physical examination. The achilles tendon was the most commonly involved tendon site 41(51.2%), followed by the quadriceps tendons 22(27.5%), and patella tendon 10(12.5%). There were no MSU deposition in healthy control group at tendon by ultrasonography. Compared with negative MSU deposition at tendon site by ultrasonography, tendon MSU positive patients had longer mean gout duration [(87.3±40.9) months vs. (7.7±2.6) months, P=0.001];higher frequency of gout flare [2(1, 2) /year vs. 1(1, 1) /year, P=0.001]; higher BMI [(26.3±2.5) kg/m2vs. (23.3±2.1) kg/m2, P=0.05]. Also, the mean serum uric acid and creatinine levels were higher in tendon MSU positive group [(584.6±87.6) μmol/L vs. (460.4±96.7) μmol/L, P=0.001] and [(90.9±33.3) μmol/L vs. (70.6±40.2) μmol/L, P=0.02] separately. Logistic regression analysis showed gout duration and flare frequency were independent risk factors for MSU deposition at tendon by ultrasonography (P < 0.01). Joint or tophi aspirations were performed in all the eighty gout patients, and positive MSU crystals in synovial fluid analysis by polarized microscopy were defined as the golden standard of gout diagnosis. When compared with the golden standard, the sensitivity and specificity were 94.0% and 78.0% separately for MSU deposition at tendon by ultrasonography.@*CONCLUSION@#Tendon involvement at the lower extremity tendons in gout is very common. Long gout disease duration and high frequency of gout flare are both independent risk factors of tendon MSU deposition by ultrasonography. Ultrasonography had good sensitivity and specificity for detecting tendinous tophi and aggregates.

Symptom variability over the course of the day in patients with stable COPD in Brazil: a real-world observational study / Variabilidade dos sintomas diários de pacientes com DPOC estável no Brasil: um estudo observacional de vida real

ABSTRACT Objective: To analyze symptoms at different times of day in patients with COPD. Methods: This was a multicenter, cross-sectional observational study conducted at eight centers in Brazil. We evaluated morning, daytime, and nighttime symptoms in patients with stable COPD. Results: We included 593 patients under regular treatment, of whom 309 (52.1%) were male and 92 (15.5%) were active smokers. The mean age was 67.7 years, and the mean FEV1 was 49.4% of the predicted value. In comparison with the patients who had mild or moderate symptoms, the 183 (30.8%) with severe symptoms were less physically active (p = 0.002), had greater airflow limitation (p < 0.001), had more outpatient exacerbations (p = 0.002) and more inpatient exacerbations (p = 0.043), as well as scoring worse on specific instruments. The most common morning and nighttime symptoms were dyspnea (in 45.2% and 33.1%, respectively), cough (in 37.5% and 33.3%, respectively), and wheezing (in 24.4% and 27.0%, respectively). The intensity of daytime symptoms correlated strongly with that of morning symptoms (r = 0.65, p < 0.001) and that of nighttime symptoms (r = 0.60, p < 0.001), as well as with the COPD Assessment Test score (r = 0.62; p < 0.001), although it showed only a weak correlation with FEV1 (r = −0.205; p < 0.001). Conclusions: Dyspnea was more common in the morning than at night. Having morning or nighttime symptoms was associated with greater daytime symptom severity. Symptom intensity was strongly associated with poor quality of life and with the frequency of exacerbations, although it was weakly associated with airflow limitation.

RESUMO Objetivo: Analisar os sintomas em diferentes momentos do dia em pacientes com DPOC. Métodos: Estudo observacional multicêntrico de corte transversal em oito centros brasileiros. Foram avaliados os sintomas matinais, diurnos e noturnos em pacientes com DPOC estável. Resultados: Foram incluídos 593 pacientes em tratamento regular, sendo 309 (52,1%) do sexo masculino e 92 (15,5%) fumantes ativos. A média de idade foi de 67,7 anos, e a média de VEF1 foi de 49,4% do valor previsto. Os pacientes com sintomas mais graves (n = 183; 30,8%), em comparação com aqueles com sintomas leves e moderados, apresentaram pior nível de atividade física (p = 0,002), maior limitação ao fluxo aéreo (p < 0,001), exacerbações ambulatoriais (p = 0,002) e hospitalares (p = 0,043) mais frequentemente e piores resultados em instrumentos específicos. Os sintomas matinais e noturnos mais frequentes foram dispneia (em 45,2% e 33,1%, respectivamente), tosse (em 37,5% e 33,3%, respectivamente) e chiado (em 24,4% e 27,0%, respectivamente). Houve forte correlação da intensidade dos sintomas diurnos com sintomas matinais (r = 0,65, p < 0,001), sintomas noturnos (r = 0,60, p < 0,001), bem como com o escore do COPD Assessment Test (r = 0,62; p < 0,001); porém, houve uma correlação fraca com VEF1 (r = −0,205; p < 0,001). Conclusões: A dispneia foi mais frequente no período matinal do que no período noturno. Ter sintomas matinais e/ou noturnos foi associado à pior gravidade dos sintomas diurnos. A intensidade dos sintomas foi fortemente associada a pior qualidade de vida e frequência de exacerbações, mas fracamente associada à limitação ao fluxo aéreo.

2020 Brazilian Thoracic Association recommendations for the management of asthma / Recomendações para o manejo da asma da Sociedade Brasileira de Pneumologia e Tisiologia - 2020

ABSTRACT The pharmacological management of asthma has changed considerably in recent decades, as it has come to be understood that it is a complex, heterogeneous disease with different phenotypes and endotypes. It is now clear that the goal of asthma treatment should be to achieve and maintain control of the disease, as well as to minimize the risks (of exacerbations, disease instability, accelerated loss of lung function, and adverse treatment effects). That requires an approach that is personalized in terms of the pharmacological treatment, patient education, written action plan, training in correct inhaler use, and review of the inhaler technique at each office visit. A panel of 22 pulmonologists was invited to perform a critical review of recent evidence of pharmacological treatment of asthma and to prepare this set of recommendations, a treatment guide tailored to use in Brazil. The topics or questions related to the most significant changes in concepts, and consequently in the management of asthma in clinical practice, were chosen by a panel of experts. To formulate these recommendations, we asked each expert to perform a critical review of a topic or to respond to a question, on the basis of evidence in the literature. In a second phase, three experts discussed and structured all texts submitted by the others. That was followed by a third phase, in which all of the experts reviewed and discussed each recommendation. These recommendations, which are intended for physicians involved in the treatment of asthma, apply to asthma patients of all ages.

RESUMO O manejo farmacológico da asma mudou consideravelmente nas últimas décadas, com base no entendimento de que a asma é uma doença heterogênea e complexa, com diferentes fenótipos e endótipos. Agora está claro que o objetivo do tratamento da asma deve ser alcançar e manter o controle da doença e evitar riscos futuros (exacerbações, instabilidade da doença, perda acelerada da função pulmonar e efeitos adversos do tratamento). Isso implica em uma abordagem personalizada, incluindo tratamento farmacológico, educação do paciente, plano de ação por escrito, treinamento para uso do dispositivo inalatório e revisão da técnica inalatória a cada visita ao consultório. Um painel de 22 pneumologistas brasileiros foi convidado a revisar criticamente evidências recentes de tratamento farmacológico da asma e a preparar esta recomendação, um guia de tratamento adaptado à nossa realidade. A escolha dos tópicos ou questões relacionadas às mudanças mais significativas nos conceitos e, consequentemente, no manejo da asma na prática clínica foi realizada por um painel de especialistas. Foi solicitado a cada especialista que revisasse criticamente um tópico ou respondesse a uma pergunta, com base em evidências, para estas recomendações. Numa segunda fase, três especialistas discutiram e estruturaram todos os textos submetidos pelos demais e, na última fase, todos revisaram e discutiram cada recomendação. As presentes recomendações se aplicam a adultos e crianças com asma e destinam-se a médicos envolvidos no tratamento da doença.

Análise dos sintomas de distúrbios osteomusculares em endodontistas, relacionados à técnica de instrumentação dos canais radiculares / Analysis of osteomuscular disorders symptoms in endodontists, related to root canals instrumentation technique

Introdução: a prática da Endodontia exige do profissional longas sessões clínicas e movimentos repetitivos na execução de manobras que exigem esforço excessivo e, muitas vezes, manutenção de postura inadequada, fatores que contribuem de forma significativa para o surgimento de sintomas dolorosos relacionados a distúrbios osteomusculares referentes ao trabalho (DORTs). Métodos: o presente estudo consistiu na aplicação de um instrumento de coleta de dados ­ que constou de dois questionários compostos por questões abertas, fechadas e mistas ­ em vinte e cinco profissionais da Odontologia com especialidade de Endodontia do município de Maringá/ PR. Os dados foram tabulados e analisados estatisticamente com o auxílio do software Statistica 8.0 e realizado o teste Exato de Fisher. Resultados: as regiões relatadas com presença de dor foram: região lombar, pescoço, braços e ombros. Os profissionais que usavam somente instrumentação rotatória não relataram dor nos braços, cotovelos, punho / dedo / mão e quadril; porém, todos apresentaram dor na região lombar e no pescoço. Entre os que utilizam somente instrumentação manual, todos afirmaram sentir dor nos locais apresentados, principalmente na região dorsal e lombar. Conclusão: o presente estudo sugere que os endodontistas estão expostos a fatores de risco em adquirir algum tipo de LER/DORT, estando diretamente associado à atividade profissional e, também, à técnica de instrumentação utilizada, sendo que as regiões mais acometidas estão relacionadas com a rotação do corpo durante o procedimento e de posturas inadequadas (AU).

Introduction: The practice of endodontics involves of long sessions and repetitive movements during the execution of maneuvers that require considerable effort often in an uncomfortable position. Such factors exert a significant influence on the emergence of symptoms related to musculoskeletal disorders. Methods: Two questionnaires were administered to 25 endodontists in the city of Maringá, Brazil. Data analysis involved Fisher's exact test with the aid of Statistica 8.0. Results: Pain was more frequent in the lower back, neck, arms and shoulders. Endodontists who used rotary equipment did not report pain in the arms, elbows, wrist/fingers/hand or hips, but all participants reported low back and neck pain. Those who only used manual instruments reported pain in all sites, especially the back. Conclusion: The present findings suggest that endodontists are exposed to risk factors for the development of work-related musculoskeletal disorders, which are directly associated with the professional activity and the use of manual instruments. The most affected anatomic regions are related to the rotation of the body during theprocedure and inadequate posture (AU).

Frequency of emergency department visits and hospitalizations due to chronic obstructive pulmonary disease exacerbations in patients included in two models of care / Frecuencia de visitas al departamento de emergencias y hospitalizaciones debido a exacerbaciones de la enfermedad pulmonar obstructiva crónica en pacientes incluidos en dos modelos de atención

Introduction: Exacerbations of chronic obstructive pulmonary disease (COPD) have a huge impact on lung function, quality of life and mortality of patients. Emergency Department visits and hospitalizations due to exacerbations cause a significant economic burden on the health system. Objective: To describe the differences in the number of emergency visits and hospitalizations due to exacerbations of COPD among patients included in two models of care of the same institution. Materials and methods: A historical cohort study in which COPD patients who are users of two models of care were included: COPD integrated care program (CICP) and general consultation of pulmonology (GCP). The first model, unlike the second one, offers additional educational activities, 24/7 telephone service, and priority consultations. The number of emergency visits and hospitalizations due to COPD exacerbations in patients who had completed at least one year of follow-up was evaluated. The multivariable Poisson regression model was used for calculating the incidence rate (IR) and the incidence rate ratio (IRR) with an adjustment for confounding factors. Results: We included 316 COPD patients (166 from the CICP and 150 from the GCP). During the year of follow-up, the CICP patients had 50% fewer emergency visits and hospitalizations than patients from the GCP (IRR=0.50, 95%CI: 0.29-0.87, p=0.014). Conclusions: COPD patients in the CICP had fewer emergency visits and hospitalizations due to exacerbations. Prospective clinical studies are required to confirm the results and to evaluate the factors that contribute to the differences.

Introducción. Las exacerbaciones de la enfermedad pulmonar obstructiva crónica (EPOC) tienen un gran impacto en la función pulmonar, la calidad de vida y la mortalidad de los pacientes. Las visitas al Departamento de Emergencias y las hospitalizaciones debido a las exacerbaciones, causan una carga económica importante para el sistema de salud. Objetivo. Describir las diferencias en el número de visitas de emergencia y hospitalizaciones debidas a exacerbaciones de la EPOC, entre los pacientes incluidos en dos modelos de atención de la misma institución. Materiales y métodos. Se trata de un estudio de cohorte histórica en el que se incluyeron pacientes que son usuarios de dos modelos de atención: el programa de atención integrada de la EPOC (CICP) y la consulta general de neumología (PCG). El primer modelo, a diferencia del segundo, ofrece actividades educativas adicionales, servicio telefónico las 24 horas del día y consultas prioritarias. Se evaluó el número de visitas de emergencia y hospitalizaciones debido a exacerbaciones de la EPOC en pacientes que habían completado, al menos, un año de seguimiento. Se utilizó el modelo de regresión multivariable de Poisson para calcular la tasa de incidencia (IR) y la razón de tasas de incidencia (IRR), con un ajuste para factores de confusión. Resultados. Se incluyeron 316 pacientes con EPOC, 166 del CICP y 150 de la PCG. Durante el año de seguimiento, los pacientes en el CICP tuvieron 50 % menos visitas de emergencia y hospitalizaciones que los pacientes en la PCG (IRR=0,50; IC95% 0,29-0,87; p=0,014). Conclusiones. Los pacientes con EPOC en el CICP, tuvieron menos visitas de emergencia y hospitalizaciones debido a las exacerbaciones. Se requieren estudios clínicos prospectivos para confirmar los resultados y evaluar los factores que contribuyen a las diferencias.

The prevalence of bruxism and related factors in patients with multiple sclerosis: a comparative study / A prevalência do bruxismo e fatores relacionados em pacientes com esclerose múltipla: um estudo comparativo

ABSTRACT Objective: To determine the prevalence of bruxism and related factors in patients with multiple sclerosis (MS). Methods: Diagnosed with relapsing-remitting MS under the 2010-revised McDonald diagnostic criteria, 182 patients without MS exacerbations during the previous three months were included in the patient group, and 145 healthy individuals made up the control group in the study. Demographic data of the participants in both groups were determined. In the patient and control groups, the diagnosis of definite bruxism was made using the International Classification of Sleep Disorders (Diagnosis and Coding Manual, Second Edition). Results: Bruxism was found in 29.7% (n = 54) of the patients and in 12.4% (n = 18) of the controls, and the difference was statistically significant (p < 0.001). Of all patients, the onset of bruxism was found in 70.4% (n = 38) after the diagnosis and in 29.6% (n = 169) prior to the diagnosis of MS. Compared with those without bruxism, the mean age (p = 0.031) and the score of the Expanded Disability Status Scale (p = 0.001) were also significantly higher among MS patients with bruxism. Between MS patients with and without bruxism, no significant differences were found in terms of sex, marital status, educational status, employment, cigarette smoking, total number of exacerbations, number of exacerbations within the previous year, and drugs used. Conclusions: The frequency of bruxism was found to be higher in the patients with MS than in the controls. Bruxism is associated with age and the Expanded Disability Status Scale score in MS patients.

RESUMO Objetivo: Neste estudo, pretendeu-se determinar a prevalência de bruxismo e fatores relacionados em pacientes com esclerose múltipla (EM). Métodos: Diagnosticados com EM remitente recidivante sob os critérios de McDonald Diagnostic revisados em 2010, 182 pacientes sem ataques de EM durante os últimos três meses foram incluídos no grupo de pacientes, e 145 indivíduos saudáveis constituíram o grupo de controle no estudo. Os dados demográficos dos participantes dos dois grupos foram determinados. Nos grupos de pacientes e controle, o diagnóstico de bruxismo definitivo foi feito usando a Classificação Internacional de Distúrbios do Sono (1) (Manual de Diagnóstico e Codificação Segunda Edição). Resultados: O bruxismo foi detectado em 29,7% (n = 54) dos pacientes e observado dentro de 12,4% (n = 18) dos controles, e a diferença foi estatisticamente significante (p <0,001). De todos os pacientes, o tempo inicial de bruxismo foi encontrado em 70,4% (n = 38) após o diagnóstico e em 29,6% (n = 169) antes do diagnóstico. Em comparação com aqueles sem bruxismo, os níveis de idade média (p = 0,031) e o escore da Escala de Status de Incapacidade Expandida (p = 0,001) também foram significativamente maiores entre os pacientes com esclerose múltipla com bruxismo. Entre os pacientes com esclerose múltipla com e sem bruxismo, não foi encontrada diferença significativa em termos de sexo, estado civil, status educacional, emprego, tabagismo, número total de ataques, número de ataques no último ano e medicamentos utilizados. Conclusões: A freqüência de bruxismo foi maior em pacientes com esclerose múltipla do que nos controles. O bruxismo está associado à idade e ao escore da Escala de Status de Incapacidade Expandida (EDSS) em pacientes com EM.

Clinical and epidemiologic characterization of patients with systemic lupus erythematosus admitted to an intensive care unit in Colombia

Abstract Objective: Describe the clinical and epidemiologic characteristics of patients with systemic lupus erythematosus (SLE) admitted to the intensive care unit (ICU). Methods: a retrospective study with medical records review of patients with systemic lupus erythematosus (SLE) admitted to the ICU between 2004 and 2015 were included. Qualitative variables were described using absolute and relative frequencies. For quantitative variables mean value and standard deviation (SD) or median value with the interquartile range (IQR) depending on data distribution. To compare groups, it was used the Student t-test or Mann Whitney U test as appropriate and Fisher's exact test. Results: 33 patients were included, with a total of 45 ICU admissions, 29 (87.9%) were females with a median age of 26 years. The median time of diagnosis of SLE was two years, (IQR 1.5-5). The most common SLE manifestation and comorbidity were renal disease and hypertension with 27 (81.8%) and 14 (42.4%) respectively. The main reason for admittance was lupus flare with 25 events (55.5%). Infection was the second cause of admission with 19 events (42.2%). The median stay time in the ICU was four days (IQR 2-7). LODS score was 6 (RIQ 5-8), and APACHE II score was 13 (RIQ 11-17.7). There were 29 infections (64.5%) of which 20 (69%) were hospital-acquired. Four (12.1%) patients died. Conclusion: Unlike most of the previously reported series, in this study SLE activity was the most common cause of admission in the ICU. A more aggressive disease and difficulties in the ambulatory setting could explain this behavior. Despite the higher percentage of lupus flares, there was lower mortality.
