Infiltração resinosa em lesões brancas cariosas e não cariosas: relato de casos / Infiltración resinosa em lesiones blancas cariosas y no cariosas: Reporte de Casos / Resinous infiltration in carious and non-carious white lesions: Case Reports

Introdução: O processo de desmineralização proveniente da cárie leva à formação de manchas brancas que são a primeira manifestação visível da doença. Os infiltrantes resinosos surgem como uma alternativa para o tratamento dessas lesões não cavitadas, pois sãoresinas de baixa viscosidade e faz parte dos procedimentos que visam uma odontologia menos invasiva. Objetivo: Este estudo objetiva relatar a experiência clínica no uso de infiltrante resinoso, Icon, em lesões de mancha branca de etiologias cariosa e não cariosa em dois pacientes distintos, insatisfeitos com a estética do seu sorriso. Descrição do caso: Ao exame clínico foi observado nos pacientes com lesões brancas. No primeiro paciente, de 14 anos, verificou-se a presença da atividade de cárie e micro cavitações. Dessa forma, o plano de tratamento perpassou orientação de higiene oral supervisionada, aplicação de verniz fluoretado, Enamelast, semanal, adequação do meio com restaurações em resina, e só então o uso do infiltrante. A segunda paciente, de 11 anos, já possuía saúde bucal adequada e tinha queixa estética devido à lesão branca não cariosa, hipoplasia, cujo plano de tratamento foi à utilização do Icon apenas. Conclusões: Nos dois casos obteve-se melhoria estética considerável com este procedimento microinvasivo. Melhoria na saúde bucal, aliado à devolução da estética, pode ser observada com o uso de infiltrantes resinosos (AU).

Introduction: The process of demineralization resulting from caries leads to the formation of white spots that are the first visible manifestation of the disease. Resin infiltrants appear as an alternative for the treatment of these non-cavitated lesions, since they are low viscosity resins and are part of the procedures that aim at a less invasive dentistry.Objective:This study aims to report the clinical experience in the use of a resin infiltrant, Icon,in white spot lesions of carious and non-carious etiologies in two different patients who were dissatisfied with the esthetics of their smiles.Methodology: On clinical examination, white lesions were observed in both patients. In the first patient,14 years old,the presence of caries activity and micro cavitations was verified. Thus, the treatment plan included supervised oral hygiene guidance, weekly application of fluoride varnish,Enamelast, adaptation of the environment with resin restorations, and, onlythen, the use of the infiltrant, Icon. The second patient, 11 years old,already had adequate oral health and had an esthetic complaint due to a non-carious white lesion, hypoplasia, whose treatment plan consisted of the use of Icon only.Conclusions:In both cases considerable esthetic improvement was obtained with this microinvasive procedure. Improvement in oral health, combined with the return of esthetics, can be observed with the use of resin infiltrants (AU).

Dying with end stage kidney disease: factors associated with place of death on a palliative care program / Fim de vida na doença renal terminal: fatores associados ao local de óbito num programa de cuidados paliativos

Abstract Introduction: End of life care of patients with end-stage kidney disease (ESKD) may be particularly challenging and requires the intervention of a specialized palliative care team (PCT). Objective: To characterize the population of ESKD patients referred to a PCT and evaluate the determinants of planned dying at home. Methods: We performed a retrospective observational cohort study of all patients with ESKD referred to our PCT between January 2014 and December 2021 (n = 60) and further characterized those with previously known ESKD regarding place of death (n = 53). Results: The majority of the patients were female and the median age was 84 years. Half of the patients were on conservative treatment, 43% were on chronic hemodialysis, and the remainder underwent hemodialysis on a trial basis and were subsequently suspended. Of those with previously known ESKD, 18% died at home and neither gender, age, cognition, performance status, comorbidities, CKD etiology, or treatment modality were associated with place of death. Anuria was significantly associated with dying at the hospital as was shorter time from dialysis suspension and death. Although not reaching statistical significance, we found a tendency towards a longer duration of palliative care follow-up in those dying at home. Conclusion: Dying at home is possible in a palliative domiciliary program regardless of age, gender, etiology of CKD, major comorbidities, and treatment modality. Anuria and shorter survival from RRT withdrawal may be limiting factors for planned dying at home. A longer follow-up by palliative care may favor dying at home.

Resumo Introdução: Os cuidados de fim de vida em doentescom doença renal terminal (DRT) podem ser desafiantes e necessitar do apoio de uma equipa especializada em cuidados paliativos (ECP). Objetivo: Caracterizar a população de doentes com DRT encaminhada à ECP e avaliar os determinantes para um fim de vida planeado no domicílio. Métodos: Realizámos um estudo de coorte observacional retrospectivo dos doentes com DRT encaminhados à ECP entre janeiro/2014 e dezembro/2021 (n = 60) e caracterizámos aqueles com DRT previamente conhecida relativamente ao local de fim de vida (n = 53). Resultados: A maioria dos pacientes eram mulheres comidade mediana de 84 anos. Metade dos doentes encontrava-se em tratamento conservador, 43% em hemodiálise crónica e os restantes suspenderam diálise iniciada agudamente. Daqueles com DRT previamente conhecida, 18% morreram em casa. Não foi objetivada associação entre género, idade, cognição, status funcional, comorbilidades, etiologia da DRC ou modalidade de tratamento da DRT e o local de óbito. A anúria e a menor sobrevida após suspensão de diálise associaram-se a um fim de vida no hospital e verificámos uma tendência para o fim de vida em casa nos doentes com mais tempo de acompanhamento pela ECP. Conclusão: O fim de vida no domicílio é possível num programa domiciliário de cuidados paliativos, independentemente de idade, sexo, etiologia da DRC, principais comorbilidades e modalidade de tratamento. A anúria e o menor tempo de sobrevida após suspensão da TRS podem ser fatores limitantes. Um acompanhamento mais longo em cuidados paliativos pode favorecer o fim de vida no domicílio.

Plant-based diets and their effects on the metabolism and survival of chronic renal patients undergoing conservative treatment

Diet therapy in conservative treatment of chronic kidney disease involves protein restriction, but there is not enough evidence to recommend a particular type of protein, whether animal or plant based. However, studies suggest that plant-based diets help reduce the consumption of total and animal protein, reduce the need for nephroprotective drugs, improve complications and bring advantages in terms of disease progression and patient survival. The article considers up-to-date data on the effects of this diet and observed that when low in protein, primarily vegetable and in some cases supplemented with ketoanalogues, it can result in positive clinical outcomes, such as: delay in the decrease in the glomerular filtration rate, lower concentrations of urea, reduction of serum creatinine and phosphorus concentrations, lower metabolic acidosis, higher insulin sensitivity and lower systemic inflammation. As a whole, this dietary pattern may be able to postpone the start of dialysis with less progression of renal insufficiency. Additional research is needed to better characterize this dietary pattern.

La dietoterapia en el tratamiento conservador de la enfermedad renal crónica implica la restricción de proteínas, pero aún no hay pruebas suficientes para recomendar un tipo concreto de proteínas, ya sean animales o vegetales. Sin embargo, los estudios sugieren que las dietas basadas en plantas ayudan a reducir la ingesta de proteínas totales y animales, disminuyen la necesidad de fármacos nefroprotectores, mejoran las complicaciones y presentan ventajas con respecto a la progresión de la enfermedad y la supervivencia de los pacientes. En este artículo se consideran datos actualizados sobre los efectos de esta dieta y se observa que, cuando es hipoproteica, principalmente vegetal y en algunos casos se complementa con cetoanálogos, puede dar lugar a resultados clínicos positivos, como una disminución retardada de la tasa de filtración glomerular, concentraciones más bajas de urea, concentraciones reducidas de creatinina y fósforo séricos, menor acidosis metabólica, mayor sensibilidad a la insulina y menor inflamación sistémica. En conjunto, este patrón dietético tiene el potencial de retrasar el inicio de la diálisis con una menor progresión de la insuficiencia renal. Es necesario seguir investigando para caracterizar mejor este patrón dietético.

Manejo y resultados de pacientes con diverticulitis aguda: experiencia de cinco años en el Hospital San Vicente Fundación / Management and results of patients with acute diverticulitis. Five year-experience at the San Vicente Fundación Hospital

Introducción. Los datos epidemiológicos de la diverticulitis en Colombia son limitados. El objetivo de este artículo fue caracterizar una población que ingresó con diverticulitis aguda al Hospital Universitario San Vicente Fundación, un centro de referencia de la ciudad de Medellín, Colombia, para analizar la presentación y comportamiento de la enfermedad en la población local, con estadísticas propias y desenlaces de la enfermedad en los últimos años. Métodos. Estudio observacional retrospectivo, descriptivo, entre enero de 2015 y diciembre de 2019. Se hizo un estudio exploratorio uni-, bi- y multivariado de factores de riesgo para fallo en el tratamiento y la mortalidad. Resultados. Se incluyeron 103 pacientes. Se presentó principalmente en mujeres y la edad promedio fue de 65 años. La diverticulitis Hinchey Ia fue la más frecuente (41,7 %) y el manejo médico fue exitoso en todos los casos, mientras que en las tipo III y IV, todos se manejaron de forma quirúrgica, con tasas de éxito entre el 50 y el 64 %. La presencia de signos de irritación peritoneal al examen físico, el recuento de leucocitos y la PCR, el ingreso a la Unidad de Cuidados Intensivos y la mortalidad aumentaron de forma directamente proporcional con el estadio de Hinchey. Conclusiones. Existe una relación directamente proporcional entre la clasificación de Hinchey y los signos de respuesta inflamatoria clínicos y paraclínicos, la necesidad de manejo quirúrgico, la estancia en la Unidad de Cuidados Intensivos y la mortalidad.

Introduction. Epidemiological data on diverticulitis in Colombia are limited. The objective of this article was to characterize a population that was admitted with acute diverticulitis to the San Vicente Fundación University Hospital, a reference center in the city of Medellín, Colombia, to analyze the presentation and behavior of the disease in the local population, with its own statistics, and outcomes of the disease in recent years. Methods. Retrospective descriptive observational study between January 2015 and December 2019. An exploratory uni-, bi- and multivariate study of risk factors for treatment failure and mortality was performed. Results. A total of 103 patients were included. The most frequent Hinchey classification was Ia (41.7%). It occurs mainly in women, mean age 65 years. Hinchey Ia diverticulitis is the most frequent and medical management is successful in 100% of cases; while in III and IV, 100% were managed surgically with success rates between 50 and 64%. The presence of peritoneal signs on physical examination, leukocyte count and CRP, ICU admission and mortality increased directly proportional with Hinchey stage. Conclusions. There is a directly proportional relationship between Hinchey staging with clinical and paraclinical signs of inflammatory response, need for surgical management, ICU stay and mortality.

Evolución clínica en pacientes con síndrome del túnel carpiano tratados con ultrasonido o infiltración con corticoesteroides / Clinical Evolution in Patients with Carpal Tunnel Syndrome Treated with Ultrasound or Corticosteroid Infiltration

Introducción. El Síndrome del túnel carpiano es la neuropatía periférica compresiva más común de la extremidad superior, que se produce por la compresión del nervio mediano. Los casos leves y moderados pueden tratarse con métodos conservadores como ultrasonido terapéutico o infiltración con corticoesteroides. Objetivo. Describir la evolución clínica de pacientes con síndrome de túnel carpiano tratados con terapia por ultrasonido e infiltración de corticoesteroides. Metodología. Ensayo clínico abierto, en pacientes con síndrome del túnel carpiano leve y moderado, que consultaron del 1 de octubre 2021 al 30 de mayo 2022. Se formaron dos grupos; el que recibió tratamiento con ultrasonido con 12 casos y el grupo tratado con infiltración con corticoesteroides con seis casos. Ambos grupos fueron intervenidos en la consulta inicial, y luego, en las cuatro y ocho semanas posteriores al inicio del tratamiento. Resultados. Se muestran los resultados descriptivos relacionados con la intensidad de dolor, valorada con la Escala Visual Numérica, la infiltración obtuvo dos casos sin dolor y cuatro con dolor moderado, contrario a ultrasonido que se mantuvo con cuatro casos leves, tres moderados y cinco intensos. En los síntomas, la infiltración redujo el número de casos en cuatro de los síntomas estudiados, en cambio el ultrasonido únicamente en dos. En severidad, valorada con el cuestionario de Boston para túnel carpal, con infiltración se obtuvieron dos casos asintomáticos y ninguno con ultrasonido. Respecto a los signos clínicos, el signo de Tinel desapareció en cuatro casos en ambos grupos, mientras que signo de Phalen desapareció en cuatro casos en ultrasonido y dos en infiltración. Conclusión. En intensidad de dolor y grado de severidad, la infiltración generó casos asintomáticos y redujo mayor cantidad de síntomas que el ultrasonido. Ambos tratamientos disminuyeron la presencia de signos clínicos

Introduction. Carpal tunnel syndrome is the most common compressive peripheral neuropathy of the upper extremity, which is caused by compression of the median nerve. Mild and moderate cases can be treated with conservative methods such as therapeutic ultrasound or corticosteroid infiltration. Objective. To describe the clinical evolution of patients with carpal tunnel syndrome treated with ultrasound therapy and corticosteroid infiltration. Methodology. A prospective open clinical trial was conducted in patients with mild and moderate carpal tunnel syndrome who consulted from October 1, 2021 to May 30, 2022. Two groups were formed: the group that received ultrasound treatment with 12 cases and the group treated with corticosteroid infiltration with six cases. Both groups were treated at the initial consultation and then at four and eight weeks after the start of treatment. Results. The descriptive results related to the intensity of pain, evaluated with the Visual Numeric Scale, are shown. Infiltration obtained two cases without pain and four with moderate pain, contrary to ultrasound which was maintained with four mild, three moderate and five intense cases. In symptoms, infiltration reduced the number of cases in four of the symptoms studied, while ultrasound reduced the number of cases in only two. In severity, assessed with the Boston carpal tunnel questionnaire, with infiltration, there were two asymptomatic cases and none with ultrasound. Regarding clinical signs, Tinel's sign disappeared in four cases in both groups, while Phalen's sign disappeared in four cases in ultrasound and two in infiltration. Conclusion. Infiltration produced asymptomatic patients and reduced more symptoms than ultrasonography in terms of pain intensity and severity. Clinical symptoms were less common with both treatments.

Trans-nasal sphenopalatine ganglion block for post-dural puncture headache management: a meta-analysis of randomized trials

Abstract Objective: To evaluate the efficacy and safety of trans-nasal Sphenopalatine Ganglion (SPG) block over other treatments for Post-Dural Puncture Headache (PDPH) management. Methods: A systematic literature search was conducted on databases for Randomized Controlled Trials (RCTs) comparing trans-nasal SPG blockade for the management of PDPH over other treatment modalities. All outcomes were pooled using the Mantel-Haenszel method and random effect model. Analyses of all outcomes were performed as a subgroup based on the type of control interventions (conservative, intranasal lignocaine puffs, sham, and Greater Occipital Nerve [GON] block). The quality of evidence was assessed using the GRADE approach. Results: After screening 1748 relevant articles, 9 RCTs comparing SPG block with other interventions (6 conservative treatments, 1 sham, 1 GON and 1 intranasal lidocaine puff) were included in this meta-analysis. SPG block demonstrated superiority over conservative treatment in pain reduction at 30 min, 1 h, 2 h, 4 h after interventions and treatment failures with "very low" to "moderate" quality of evidence. The SPG block failed to demonstrate superiority over conservative treatment in pain reduction beyond 6 h, need for rescue treatment, and adverse events. SPG block demonstrated superiority over intranasal lignocaine puff in pain reduction at 30 min, 1 h, 6 h, and 24 h after interventions. SPG block did not show superiority or equivalence in all efficacy and safety outcomes as compared to sham and GON block. Conclusion: Very Low to moderate quality evidence suggests the superiority of SPG block over conservative treatment and lignocaine puff for short-term pain relief from PDPH.

Manejo conservador del neumotórax oculto en trauma

Introducción: El neumotórax oculto (NTXO) se encuentra hasta en el 15% de los traumatismos torácicos. Existen antecedentes del manejo conservador de esta patología (sólo observación), aunque su práctica continúa siendo discutida, especialmente, en traumatismos penetrantes. El objetivo de este trabajo es describir nuestra experiencia en el manejo conservador del NTXO. Materiales y Método: Estudio de cohorte retrospectivo realizado durante un período de 3 años en un Hospital de Trauma nivel I. Se incluyeron pacientes con traumatismo torácico (cerrado o penetrante) con NTXO. Se dividieron en dos grupos (conservados o drenados), realizándose una comparación de su evolución. Resultados: En 3 años fueron admitidos con traumatismo torácico 679 pacientes. De 93 pacientes con NTXO, 74 (80%) fueron conservados inicialmente y 19 (20%) tratados con drenaje pleural. Dos (3%) presentaron progresión del neumotórax en el seguimiento radiológico (conservación fallida). No se registraron complicaciones relacionadas con la ausencia de drenaje pleural. Las complicaciones y estancia hospitalaria fueron menores en el grupo de manejo conservador. Conclusión: Pacientes con NTXO por traumatismo de tórax (cerrado o penetrante), sin requerimiento de ventilación asistida y hemodinámicamente estables, pueden manejarse de manera conservadora con un monitoreo cercano durante 24 horas en forma segura, con menor tasa de complicaciones y de estancia hospitalaria.

Background: Occult pneumothorax (OPTX) is found in up to 15% of chest injuries. There is a history of conservative management of this pathology (only observation), although its practice continues to be discussed, especially in penetrating trauma. The objective of this paper is to describe our experience in the conservative management of OPTX. Materials and Method: Retrospective cohort study conducted over a 3-year period at a level I Trauma Center. Patients with thoracic trauma (blunt or penetrating) with OPTX were included. They were divided into two groups (preserved or drained) comparing their evolution. Results: Over a 3-year period 679 patients were admitted with chest trauma. From 93 patients with OPTX, 74 (80%) were initially preserved and 19 (20%) drained. Two patients (3%) presented pneumothorax progression in the follow-up imaging. There were no complications related to the absence of pleural drainage. Complications and hospital stay were lower in the conservative management group. Conclusion: Patients with OPTX due to chest trauma (blunt or penetrating), without requiring assisted ventilation and hemodynamically stable, can be safely conservative managed with close monitoring for 24 hours, with a lower rate of complications and hospital stay.

Conservative treatment of ameloblastoma: report of 2 cases and review of the literature / Tratamiento conservador de ameloblastoma: reporte de 2 casos y revisión de la literatura

Introduction: ameloblastomas correspond to one of the most prevalent odontogenic tumors in developing countries, they are mainly located in the mandible, and their treatment has been widely discussed over the years, using radical or conservative treatments depending on different variables. Clinical case: we present two cases of patients with ameloblastoma who underwent conservative treatment without the use of adjuvant therapy, obtaining satisfactory results at 36 and 48 months. Discussion: due to a possible recurrence with conservative treatment, radical management has been suggested, however, the choice of treatment should be based on a series of clinical, histological, and radiographic characteristics.

Introducción: Los ameloblastomas corresponden a uno de los tumores odontogénicos más prevalentes en los países en desarrollo, se ubican principalmente en la mandíbula, y su tratamiento ha sido ampliamente discutido a lo largo de los años, utilizando tratamientos radicales o conservadores dependiendo de distintas variables. Caso clínico: se presentan dos casos de pacientes con un ameloblastoma a quienes se les realizó tratamiento conservador sin uso de terapia coadyuvante, obteniendo resultados satisfactorios a los 36 y 48 meses. Discusión: Debido a una posible recurrencia con un tratamiento conservador, se ha sugerido manejo radical, sin embargo, la elección de tratamiento debe ser en base a una serie de características clínicas, histológicas y radiográficas.

Manejo das disfunções temporomandibulares. Parte I: tratamento conservador / Management of temporomandibular joint disorders. Part I: conservative treatment

Objetivo: Apresentar as modalidades de tratamentos conservadoras e minimamente invasivas mais usadas disponíveis no arsenal terapêutico das desordens temporomandibulares (DTM). Revisão da literatura: Os objetivos do tratamento invariavelmente incluem redução da dor, diminuição das atividades parafuncionais e restauração da função. Dentre as alternativas conservadoras e minimamente invasivas, podemos citar os dispositivos interoclusais, exercícios terapêuticos, eletrofototermoterapia, agulhamento seco e infiltração de anestésicos locais em pontos gatilho, injeção de sangue autógeno para controle da luxação mandibular, terapia cognitivo comportamental, toxina botulínica, viscossuplementação, controle farmacológico da dor aguda e crônica. As DTMs afetam uma proporção significativa da população. Somente após o fracasso das opções não invasivas é que devem ser iniciados tratamentos mais invasivos e irreversíveis. No entanto, algumas condições, como a anquilose e neoplasias, por exemplo, são essencialmente tratadas cirurgicamente e tentativas de tratamentos conservadores podem trazer piora na qualidade de vida ou risco de morte. Considerações finais: Uma abordagem de equipe multidisciplinar para o manejo é essencial no cuidado fundamental de todos os pacientes com DTM, para que o tratamento possa ser especificamente adaptado às necessidades individuais do paciente.

Aim: To present the most widely used conservative and minimally invasive treatment modalities available in the therapeutic arsenal for temporomandibular disorders (TMD). Literature review: Treatment goals invariably include pain reduction, reduction of parafunctional activities and restoration of function. Among the conservative and minimally invasive alternatives, we can mention interocclusal devices, therapeutic exercises, electrophototherapy, dry needling and infiltration of local anesthetics in trigger points, autogenous blood injection to control mandibular dislocation, cognitive behavioral therapy, botulinum toxin, viscosupplementation, pharmacological control of acute and chronic pain. TMD affects a considerable proportion of the population. Only after non-invasive options have failed should more invasive and irreversible treatments be initiated. However, some conditions, such as ankylosis and neoplasms, for example, are treated surgically and attempts at conservative treatments can lead to worsening quality of life or risk of death. Conclusions: A multidisciplinary team approach to management is essential in the fundamental care of all TMD patients, so that treatment can be specifically tailored to the patient's individual needs.

Spontaneous bilateral pneumothorax in a previously healthy COVID-19 patient: A case report

Coronavirus disease 2019 (COVID-19) is commonly linked with mild cough, fever, and shortness of breath symptoms. However, there have been reports of pneumothorax, which particularly occurred at least 1 week following symptom onset in elderly COVID-19 patients. Spontaneous pneumothorax (SP) is an uncommon but possibly fatal complication of COVID-19 pneumonia and is rarely reported in non-intubated patients. We report a case of a healthy, non-smoker 35-year-old young woman who presented with a 7-day cough, fever, and sudden shortness of breath. She was diagnosed with severe COVID-19 pneumonia, experienced a right SP, and developed a second pneumothorax on the contralateral side. She improved gradually following chest tube insertion in the right lung and conservative management for the left pneumothorax.

Dispositivos médicos en tiempos de pandemia: Eficacia de un sistema artesanal de alto flujo en el manejo de pacientes hospitalizados por COVID-19

Evaluar la eficacia del dispositivo artesanal de asistencia respiratoria no invasivo de administración de presión positiva continua en las vías respiratorias (CPAP) Wayrachi en comparación con la cánula de alto flujo comercial (CAF) para el tratamiento de pacientes con SARS-CoV-2. Estudio realizado en el Hospital Honorio Delgado Espinoza de Arequipa (Hospital COVID-MINSA Arequipa). Se evaluó a las historias clínicas de pacientes con SARS-CoV-2, de severidad moderada o grave que requerían asistencia respiratoria no invasiva, hospitalizados en el servicio de medicina interna durante la segunda ola de COVID en el Perú. Se realizó un análisis de supervivencia considerando los días a la muerte comparando al Wayrachi con la CAF. Se exploró el efecto de las variables sobre la muerte mediante una regresión de Cox. Resultados: Se evaluaron 114 pacientes tratados con Wayrachi (56,44 %) y 88 con CAF (43,5 %), observándose una frecuencia de muerte de 34,2 % y 34,1 % respectivamente. Al comparar la frecuencia de muerte, o su sobrevida, en ambos manejos no se observó una diferencia significativa (p=0,986 y p=0,928), esto se mantuvo en el modelo multivariado. El CPAP Wayrachi tuvo resultados similares a los presentados por el equipo CAF comercial lo que lo indica como una opción eficaz para el manejo de pacientes COVID que requieran soporte respiratorio no invasivo.

To evaluate the efficacy of the Wayrachi continuous positive airway pressure (CPAP) non-invasive respiratory support device compared to the commercial high-flow cannula (CAF) for the treatment of patients with SARS-CoV-2. Study carried out at the Honorio Delgado Espinoza Hospital in Arequipa (Hospital COVID-MINSA Arequipa). The medical records of patients with SARS-CoV-2, of moderate or severe severity, who required non-invasive respiratory assistance, hospitalized in the internal medicine service during the 2nd wave of COVID in Peru, were evaluated. A survival analysis was performed considering days to death comparing Wayrachi with CAF. The effect of variables on death was explored using Cox regression. Results: 114 patients treated with Wayrachi (56.44%) and 88 with CAF (43.5%) were evaluated, observing a frequency of death of 34.2% and 34.1%, respectively. When comparing the frequency of death, or its survival, in both managements, no significant difference was observed (p=0.986 and p=0.928), this was maintained in the multivariate model. The Wayrachi CPAP had similar results to those presented by the commercial CAF equipment, which indicates it as an effective option for the management of COVID patients who require non-invasive respiratory support.

Ameloblastoma uniquístico con patrón plexiforme: revisión de la literatura a propósito de un caso clínico / Unicystic ameloblastoma with a plexiform pattern: literature review regarding a clinical case

En 1827 el médico James William Cusack describió una lesión tumoral expansiva con características clínicas similares al ameloblastoma. Para el 2017 la Organización Mundial de la Salud lo clasificó como un tumor odontogénico benigno de origen epitelial. En la actualidad hemos aceptado la teoría de su etiología asociada con una mutación en el biomarcador BRAF-V600E, donde se presentan claras heterogeneidades extra/intratumorales en el metabolismo de la tumorogénesis; la mutación en BRAF genera cambios en la regulación de la odontogénesis, en conjunto con el gen CDC73 presente en el cromosoma 1 q25-q32, lo que produce un cambio en la proteína parafibromina que inhibe la proliferación celular durante el crecimiento y la división celular, esto afecta en conjunto al gen p53 y su homólogo p63 presentes en el cromosoma 17, por lo que se tiene como resultado la expresión de quistes y tumores dentales como el ameloblastoma. La presente obra muestra el caso clínico de un paciente femenino de 11 años de edad con aumento de volumen en la región submandibular izquierda de 7 × 4 cm, con seis años de evolución; de tal manera que fue diagnosticado con ameloblastoma uniquístico y tratado de forma conservadora mediante enucleación, posteriormente fue valorada anualmente hasta que la paciente cumplió los 18 años de edad (AU)

In 1827, physician James William Cusack described an expansive tumor lesion with clinical characteristics similar to ameloblastoma. For 2017, the World Health Organization classified it as a benign odontogenic tumor of epithelial origin. Currently, we have accepted the theory of its etiology associated with a mutation in the BRAF-V600E biomarker, where there are clear extra/intratumoral heterogeneities in the metabolism of tumorigenesis; the BRAF mutation generates changes in the regulation of odontogenesis, together with the CDC73 gene present on chromosome 1 q25-q32, producing a change in the parafibromin protein that inhibits cell proliferation during cell growth and division, which together it affects the p53 gene and its p63 homolog is present on chromosome 17, resulting in the expression of dental cysts and tumors such as ameloblastoma. This work provides the clinical case of an 11-year-old patient with an increase in volume in the left submandibular region of 7 × 4 cm of 6 years of evolution. Being diagnosed as a unicistic ameloblastoma and treated conservatively by enucleation, it is subsequently evaluated annually until the patient reaches 18 years of age (AU)

Análise das gestações ectópicas íntegras tratadas com o protocolo de dose única de metotrexato / Analysis of unruptured ectopic pregnancies treated with single-dose methotrexate protocol

Objetivo: Avaliar o índice de sucesso do tratamento da gravidez ectópica com o protocolo de dose única do metotrexato e verificar sua correlação com variáveis clínicas e dados dos exames complementares. Métodos: É um estudo epidemiológico observacional, analítico, retrospectivo, de delineamento transversal. Foi realizado de janeiro de 2014 a agosto de 2020 em um hospital público, de ensino, em nível terciário, do Sul do Brasil. Em 73 casos com diagnóstico de gestação ectópica íntegra, foi utilizado o protocolo de dose única de metotrexato intramuscular, com a dose de 50 mg/m2 de superfície corporal. As variáveis do estudo foram relacionadas ao sucesso do tratamento e abordaram as características clínicas na admissão, dos exames complementares e do tratamento realizado. As variáveis foram comparadas por análise de regressão de Poisson. O nível de significância estabelecido foi de p < 0,05. Resultados: O índice de sucesso foi de 83,6%, e em nove casos foi necessária uma segunda dose da medicação. Nível de ß-hCG inicial superior a 5.000 mUI/mL foi relacionado a menor chance de sucesso (odds ratio ajustado de 0,20 [0,05-0,95]). Tamanho da imagem anexial, presença de líquido livre na cavidade abdominal e demais variáveis estudadas não afetaram a chance de sucesso do tratamento. Conclusão: O protocolo de dose única de metotrexato mostrou-se uma opção válida para o tratamento da gestação ectópica íntegra, notadamente quando o nível de ß-hCG inicial é inferior 5.000 mUI/mL.

Objective: The purpose of the present study is to evaluate the success rate of treatment of ectopic pregnancy with the single-dose methotrexate protocol and to verify its correlation with clinical variables and complementary exam data. Methods: This is a retrospective epidemiological observational analytical cross-sectional study. It was carried out from January 2014 to August 2020 in a tertiary level teaching hospital in southern Brazil. In 73 cases with a diagnosis of intact ectopic pregnancy, the intramuscular methotrexate single-dose protocol was applied with a dose of 50 mg/m2 of body surface. The study variables were related to the success of the treatment and addressed the clinical characteristics on admission, the complementary exams and the treatment performed. The variables were compared by Poisson regression analysis. The level of significance was set at p < 0.05. Results: The success rate was 83.6%, and in nine cases a second dose of the medication was necessary. An initial ß-hCG level greater than 5,000 mIU/mL was related to a lower chance of success (adjusted odds ratio of 0.20 [0.05- 0.95]). The size of the adnexal image, the presence of free fluid in the abdominal cavity and other variables studied did not affect the chance of a successful treatment. Conclusion: The methotrexate single-dose protocol proved to be a valid option for the treatment of intact ectopic pregnancy, notably when the initial ß-hCG level is below 5,000 mIU/mL.

Conservative management of newborns with 35 weeks or more of gestational age at risk for early-onset sepsis: a Brazilian cohort study

Abstract Objective: To evaluate the conservative management of newborns born at ≥35 weeks of gestational age, at risk for early-onset neonatal sepsis (EOS). Methods: Retrospective, analytic cohort study (2016 to 2019), including newborns ≥35 weeks of gestational at risk of EOS, asymptomatic at birth, managed conservatively in full rooming-in: serial physical examination and clinical observation for at least 48 h. They were classified into three groups, according to the clinical course: asymptomatic (group A), symptomatic for other reasons (group B), and with sepsis (group C). Risk factors, clinical signs and differential diagnoses of sepsis, length of stay, and discharge conditions were evaluated. Results: The authors evaluated 769 asymptomatic newborns at risk of EOS. (mean birth weight 2999 ± 485 g and gestational age 37.6 ± 1.7 weeks, respectively) corresponding to 12.2% of rooming-in admissions. The most prevalent risk factors were colonization by Group B Streptococcus (29%), prolonged rupture membrane duration (21.9%) and preterm labor (21.4%). Most of all of them (53.9%) remained asymptomatic (group A). Group B corresponded for 45.3%, and the most common clinical signs were hypothermia (24.5%), tremors (8.7%) and vomiting (8%). Environmental dysthermia (50.7%), prematurity (20.0%), and feeding intolerance (15.7%) were common in Group B. Laboratory tests were performed in 3.5%. Five patients (one confirmed) comprised group C (0.8/1,000 live births). There were no deaths. The median length of stay was 64 h (IQR 50-93). Conclusion: The rate of clinical/confirmed EOS was low. Most of the symptomatic patients only needed clinical evaluation to rule out sepsis. Management was shown to be safe.

Resultados de la cirugía conservadora y radical de la mama en pacientes operadas en el Centro de Investigaciones Médico Quirúrgicas, Cuba / Results of Conservative or Radical Breast Surgeries in Patients Operated on at Centro de Investigaciones Médico Quirúrgicas, Cuba

Introducción: El cáncer ha causado más muertes que todas las guerras y catástrofes conocidas. En particular, el cáncer de mama se ha convertido en una pandemia que amenaza con seguir propagándose. Objetivo: Describir las diferencias en cuanto a los resultados obtenidos de la cirugía conservadora y radical como tratamiento del cáncer de mama. Métodos: Se realizó un estudio analítico, observacional, descriptivo y retrospectivo en un universo de 177 pacientes con diagnóstico de cáncer de mama en el servicio de Cirugía General del Centro de Investigaciones Médico Quirúrgicas de La Habana, Cuba. Todas recibieron tratamiento quirúrgico en el período comprendido de enero de 2011 a diciembre de 2016. Resultados: De las pacientes estudiadas, el 92,09 por ciento no presentaron antecedentes de patología mamaria, mientras que el 36,72 por ciento tuvieron como antecedente patológico familiar cáncer de mama. Predominaron las pacientes mayores de 70 años en ambas técnicas quirúrgicas. En el grupo de 30-40 años solamente se practicaron técnicas conservadoras. Con respecto al estadiamiento, predominó la etapa II de la enfermedad. La sobrevida global a los 5 años fue superior al 90 por ciento, mientras que el intervalo libre de enfermedad se mantuvo en valores similares para ambas técnicas. Conclusiones: Se realizaron mayor número de cirugías conservadoras de mama en pacientes que se encontraban en etapas clínicas más tempranas de la enfermedad y la sobrevida global de los procedimientos conservadores fue ligeramente mayor(AU)

Introduction: Cancer has caused more deaths than all known wars and catastrophes. Particularly speaking, breast cancer has become a pandemic that threatens to continue to spread. Objective: To describe the differences based on the results obtained from conservative and radical surgery as a treatment for breast cancer. Methods: An analytical, observational, descriptive and retrospective study was carried out with a universe of 177 female patients diagnosed with breast cancer in the general surgery service of Centro de Investigaciones Médico Quirúrgicas, of La Habana, Cuba. All of them received surgical treatment in the period from January 2011 to December 2016. Results: 92.09 percent of the patients studied had no history of breast pathology, while 36.72 percent had breast cancer as a family pathological history. Patients over 70 years of age predominated in both surgical techniques. In the group of 30-40 years of age only conservative techniques were performed. With respect to staging, there was a predominance of the disease in stage II. Overall survival at 5 years was higher than 90 percent, while the disease-free interval remained at similar values for both techniques. Conclusions: A greater amount of breast-conserving surgeries were performed in patients at earlier clinical stages of the disease, while overall survival of conservative procedures was slightly higher(AU)

Self-reported and objective sleep duration in patients with CKD: are they telling the same story? / Duração do sono autorrelatada e objetiva em pacientes com DRC: contam a mesma história?

Abstract Introduction: There is disagreement between data on sleep duration obtained from questionnaires and objective measurements. Whether this is also true for individuals with CKD is unknown. Here we compared self-reported sleep duration with sleep duration obtained by actigraphy. Methods: This prospective study included adult individuals with stage 3 CKD recruited between September/2016 and February/2019. We evaluated subjective sleep duration by asking the following question: "How many hours of actual sleep did you get at night?" Results: Patients (N=34) were relatively young (51 ± 13 years). Self-reported and measured sleep duration were 7.1 ± 1.7 and 6.9 ± 1.6 hours, respectively, with no correlation between them (p=0.165). Although the mean difference between measurements was 0.21 h, the limits of agreement ranged from -3.7 to 4.1 h. Conclusion: Patients with CKD who are not on dialysis have an erroneous sleep perception. Data on sleep duration should be preferentially obtained from objective measurements in patients with CKD.

Resumo Introdução: Há discordância entre os dados sobre duração do sono obtidos a partir de questionários e medições objetivas. Não se sabe se isto também é verdade para indivíduos com DRC. Aqui comparamos a duração do sono autorrelatada com a duração do sono obtida por meio de actigrafia. Métodos: Este estudo prospectivo incluiu indivíduos adultos com DRC estadio 3 recrutados entre Setembro/2016 e Fevereiro/2019. Avaliamos a duração subjetiva do sono, fazendo a seguinte questão: "Quantas horas de sono real você teve à noite?" Resultados: Os pacientes (N=34) eram relativamente jovens (51 ± 13 anos). A duração do sono autorrelatada e mensurada foi de 7,1 ± 1,7 e 6,9 ± 1,6 horas, respectivamente, sem correlação entre elas (p=0,165). Embora a diferença média entre as medições tenha sido de 0,21 h, os limites de concordância variaram de -3,7 a 4,1 h. Conclusão: Pacientes com DRC que não estão em diálise apresentam uma percepção equivocada do sono. Dados sobre a duração do sono devem ser obtidos preferencialmente a partir de medições objetivas em pacientes com DRC.

A política social e o conservadorismo econômico: o que revela o período recente? / Social policy and economic conservatism: what do recent years reveal? / Política social y conservadurismo económico: ¿qué revela el período reciente?

O objetivo do artigo é averiguar se os brasileiros ficaram mais conservadores em termos econômicos, em especial, pós-2013, a despeito dos ganhos das gestões de centro-esquerda no campo social. Como metodologia, se apresenta uma análise descritiva de dados de diversas fontes, bem como a revisão da literatura sobre os protestos de 2013. Os resultados, com contribuição à literatura devido à amplitude de informações e de abordagem, apontam o avanço da política social com reflexos na queda da pobreza e da desigualdade, porém, com retrocessos se consubstanciando na Emenda Constitucional 95 e nas reformas trabalhista e previdenciária. Em meio à inflexão iniciada com as manifestações de 2013, a conclusão a que se chega é que parece ter havido uma onda de conservadorismo econômico, que teria atingido seu pico em algum momento no quinquênio posterior a 2013

The purpose of the paper is to investigate whether Brazilians have become more conservative in economic terms, especially after 2013, despite the gains of the center-left administrations in the social field. As a methodology, a descriptive analysis of data from different sources is presented, as well as a literature review on the 2013 protests. With contribution to the literature due to the breadth of data and approaches, the results point to the progress of social policy with repercussions on the fall of poverty and inequality, however, with setbacks materializing in the Constitutional Amendment 95 and in labor and social security reforms. Amid the inflection that started with the 2013 demonstrations, the conclusion is that there seems to have been a wave of economic conservatism, which would have reached its peak at some point in the five years after 2013

El objetivo del artículo es investigar si, a pesar de los avances logrados por las administraciones de centro-izquierda en el campo social, los brasileños se volvieron más conservadores en términos económicos, especialmente des-pués de 2013. Como metodología, se presenta un análisis descriptivo de datos de diferentes fuentes, y una revisión de la literatura sobre las protestas de 2013. Se identifica un avance de la política social con consecuencias en términos de reducción de la pobreza y de la desigualdad, sin embargo, con retrocesos, consustanciados en la Enmienda Constitucional 95 y en reformas laboral y previsional. Se concluye que parece haber habido una ola de conservadurismo económico, que habría alcanzado su pico en algún momento del quinquenio posterior a 2013
