ABSTRACT

Abstract Introduction: The standard management of orbital cellulitis is to administer a combination of intravenous broad-spectrum antibiotics along with treatment of associated sinusitis. Objective: The purpose of this study was to evaluate whether the addition of corticosteroids could lead to earlier resolution of inflammation and improve disease outcome. Methods: We independently searched five databases (PubMed, SCOPUS, Embase, the Web of Science, and the Cochrane database) for studies published as recent as December 2019. Of the included studies, we reviewed orbital cellulitis and disease morbidity through lengths of hospitalization, incidence of surgical drainage, periorbital edema, vision, levels or C-reactive protein, and serum WBC levels in order to focus on comparing steroid with antibiotics treated group and only antibiotics treated group. Results: Lengths of hospitalization after admission as diagnosed as orbital cellulitis (SMD = −4.02 [−7.93; −0.12], p -value = 0.04, I2 = 96.9%) decrease in steroid with antibiotics treated group compared to antibiotics only treated group. Incidence of surgical drainage (OR = 0.78 [0.27; 2.23], p -value = 0.64,I2 = 0.0%) was lower in the steroid with antibiotics treated group compared to the antibiotics only treated group. Conclusion: Use of systemic steroids as an adjunct to systemic antibiotic therapy for orbital cellulitis may decrease orbital inflammation with a low risk of exacerbating infection. Based on our analysis, we concluded that early use of steroids for a short period can help shorten hospitalization days and prevent inflammation progression.


Resumo Introdução: O tratamento padrão da celulite orbitária inicia-se com uma combinação de antibióticos intravenosos de amplo espectro concomitante ao tratamento do seio comprometido. Objetivos: O objetivo deste estudo foi avaliar se a adição de corticosteroides poderia levar a uma resolução mais precoce da inflamação e melhorar o desfecho da doença. Método: Fizemos uma pesquisa independente em cinco bancos de dados (PubMed, SCOPUS, Embase, Web of Science e o banco de dados Cochrane) em busca de estudos publicados até dezembro de 2019. Dos estudos incluídos, revisamos a celulite orbitária e a morbidade da doença através dos períodos de internação, incidência de drenagem cirúrgica, edema periorbital, visão, níveis de proteína C-reativa e níveis séricos de leucócitos com foco na comparação do grupo tratado com esteroides e antibióticos e do grupo tratado apenas com antibióticos. Resultados: Os tempos de internação após a admissão dos diagnosticados com celulite orbitária (SMD = -4,02 [-7,93; -0,12], p-valor = 0,04, I2 = 96,9%) diminuíram no grupo tratado com esteroides e antibióticos em comparação ao grupo tratado apenas com antibióticos. A incidência de drenagem cirúrgica (OR = 0,78 [0,27; 2,23], p-valor = 0,64, I2 =0,0%) foi menor no grupo tratado com esteroides e antibióticos em comparação com o grupo tratado apenas com antibióticos. Conclusão: O uso de esteroides sistêmicos como adjuvante da antibioticoterapia sistêmica para celulite orbitária pode diminuir a inflamação orbitária com baixo risco de agravar a infecção. Com base em nossa análise, concluímos que o uso precoce de esteroides por um curto período pode ajudar a encurtar os dias de internação e prevenir a progressão da inflamação.

ABSTRACT

ABSTRACT Adrenal steroid biosynthesis and its related pathology are constant evolving disciplines. In this paper, we review classic and current concepts of adrenal steroidogenesis, plus control mechanisms of steroid pathways, distribution of unique enzymes and cofactors, and major steroid families. We highlight the presence of a "mineralocorticoid (MC) pathway of zona fasciculata (ZF)", where most circulating corticosterone and deoxycorticosterone (DOC) originate together with 18OHDOC, under ACTH control, a claim based on functional studies in normal subjects and in patients with 11β-, and 17α-hydroxylase deficiencies. We emphasize key differences between CYP11B1 (11β-hydroxylase) and CYP11B2 (aldosterone synthase) and the onset of a hybrid enzyme - CYP11B1/CYP11B2 -, responsible for aldosterone formation in ZF under ACTH control, in "type I familial hyperaldosteronism" (dexamethasone suppressible). In "apparent MC excess syndrome", peripheral conversion of cortisol to cortisone is impaired by lack of 11β-hydroxysteroid dehydrogenase type 2, permitting free cortisol access to MC receptors resulting in severe hypertension. We discuss two novel conditions involving the synthesis of adrenal androgens: the "backdoor pathway", through which dihydrotestosterone is formed directly from androsterone, being relevant for the fetoplacental setting and sexual differentiation of male fetuses, and the rediscovery of C19 11-oxygenated steroids (11-hydroxyandrostenedione and 11-ketotestosterone), active androgens and important markers of virilization in 21-hydroxylase deficiency and polycystic ovaries syndrome. Finally, we underline two enzyme cofactor deficiencies: cytochrome P450 oxidoreductase which partially affects 21- and 17α-hydroxylation, producing a combined clinical/hormonal picture and causing typical skeletal malformations (Antley-Bixler syndrome), and PAPSS2, coupled to SULT2A1, that promotes sulfation of DHEA to DHEAS, preventing active androgens to accumulate. Its deficiency results in reduced DHEAS and elevated DHEA and androgens with virilization. Future and necessary studies will shed light on remaining issues and questions on adrenal steroidogenesis.

ABSTRACT

En la actualidad, las guías basadas en la evidencia constituyen una de las herramientas más útiles para mejorar la salud pública y la práctica clínica. Su finalidad es formular intervenciones con sólidas pruebas de eficacia, evitar riesgos innecesarios, utilizar los recursos de forma eficiente, disminuir la variabilidad clínica y, en esencia, mejorar la salud y garantizar una atención de calidad, razón de ser de los sistemas y servicios de salud. Las presentes directrices se elaboraron siguiendo la metodología GRADE con el apoyo de un panel de expertos clínicos de distintos países, todos ellos convocados por la Organización Panamericana de la Salud. Por medio de la respuesta a doce preguntas clave sobre el diagnóstico clínico y el tratamiento del dengue, el chikunguña y el zika, se formulan recomendaciones basadas en evidencia para pacientes pediátricos, jóvenes, adultos, personas mayores y embarazadas expuestos a estas enfermedades o con sospecha o diagnóstico confirmado de infección. La finalidad de las directrices es evitar la progresión a las formas graves y a los eventos mortales que puedan causar. Las recomendaciones están dirigidas a profesionales de la salud, incluidos el personal médico general, residente y especialista; y los profesionales de enfermería, así como a estudiantes de medicina y enfermería, quienes de una u otra forma participan en la atención de pacientes con sospecha de dengue, chikunguña o zika. También se dirige a los administradores de las unidades de salud y a los equipos directivos de los programas nacionales de prevención y control de enfermedades arbovirales, quienes tienen la responsabilidad de facilitar el proceso de aplicación de estas directrices. Esperamos que esta publicación beneficie no solo al personal de salud, que dispondrá de información científica actualizada y de la mejor calidad posible, sino a los menores, los adultos, las embarazadas, las personas mayores y la población en general, quienes recibirán una mejor atención de salud prestada por personal médico debidamente capacitado.


Evidence-based guidelines are one of the most useful tools for improving public health and clinical practice. Their purpose is to formulate interventions based on strong evidence of efficacy, avoid unnecessary risks, use resources efficiently, reduce clinical variability and, in essence, improve health and ensure quality care, which is the purpose of health systems and services. These guidelines were developed following the GRADE methodology, with the support of a panel of clinical experts from different countries, all convened by the Pan American Health Organization. By responding to twelve key questions about the clinical diagnosis and treatment of dengue, chikungunya, and Zika, evidence-based recommendations were formulated for pediatric, youth, adult, older adult, and pregnant patients who are exposed to these diseases or have a suspected or confirmed diagnosis of infection. The purpose of the guidelines is to prevent progression to severe forms of these diseases and the fatal events they may cause. The recommendations are intended for health professionals, including general, resident, and specialist physicians, nursing professionals, and medical and nursing students, who participate in caring for patients with suspected dengue, chikungunya, or Zika. They are also intended for health unit managers and the executive teams of national arboviral disease prevention and control programs, who are responsible for facilitating the process of implementing these guidelines.

ABSTRACT

Solanum nudum Dunal (Solanaceae) is most commonly known andused by the population of the colombian Pacific coast as an antimalarial treatment. This article study into optimization and quantitative analysis of compounds steroidal over time of development of this species when grown in vitro and wild. A new steroidal compound named SN6 was elucidated by NMR and a new method of quantification of seven steroidal compounds (Diosgenone DONA and six steroids SNs) using HPLC-DAD-MS in extracts of cultures in vitroand wild was investigated. Biology activity of extracts was found to a range of antiplasmodial activity in FCB2 and NF-54 with inhibitory concentration (IC50) between (17.04 -100µg/mL) and cytotoxicity in U-937 of CC50 (7.18 -104.7µg/mL). This method creates the basis for the detection of seven sterols antiplasmodial present in extracts from S. nudum plant as a quality parameter in the control and expression of phytochemicals.

ABSTRACT

La hiperglicemia y/o diabetes inducida por esteroides, se define como la elevación de la glicemia, causada por la acción de los fármacos glucocorticoideos, sobre el metabolismo de los carbohidratos, y presenta una prevalencia entre un 20% al 50%, en pacientes sin diabetes previa, existiendo mayor riesgo para esta patología en pacientes con diabetes pre-existente, obesidad, uso crónico de esteroides o en dosis altas, entre otros. El diagnóstico se rige por los criterios para diabetes en la mayoría de los casos. No obstante, existen casos en donde la hiperglicemia por esteroides es sub-diagnosticada. Su manejo se basa en el tratamiento farmacológico (antidiabéticos orales, subcutáneos e insulina) y no farmacológico (dieta y ejercicio), tomando en cuenta, el patrón glicémico, peso, edad, co-morbilidades, dosis, tipo y tiempo de uso de los esteroides. La relevancia de conocer como diagnosticar y tratar dicha patología, se debe al riesgo de ingreso hospitalario, de infección, de mala cicatrización y de mortalidad en casos no tratados. En vista del aumento del uso de glucocorticoides en la actualidad, se hace una revisión del abordaje terapéutico de la hiperglicemia y diabetes inducida por esteroides.


Hyperglycemia and Steroid-induced Diabetes is defined as the elevation of glycemia caused by the action of glucocorticoid drugs on carbohydrate metabolism, with a prevalence between 20% and 50% in patients without Diabetes. Though, there is a greater risk of this pathology in patients with pre-existing Diabetes, Obesity, chronic use of steroids or in high doses, among others. In most cases, the diagnosis is governed by the criteria of Diabetes; however, there are cases where hyperglycemia Steroid-induced is under-diagnosed. Its management is based on pharmacological treatment (oral and subcutaneous hypoglycemic agents and insulin) and non-pharmacological treatment (diet and exercise), in accordance with the glycemic pattern, weight, age, co-morbidities, dose, type and the duration of the use of steroid. The relevance of knowing how to diagnose and treat this pathology is the risk of hospital admission, infection, poor healing and mortality in untreated cases. In view of the increased use of glucocorticoids nowadays, a review is made about the therapeutic approach to hyperglycemia and steroid-induced Diabetes.

ABSTRACT

Objective: To investigate the efficacy and safety of adrenocorticotropic hormone (ACTH) in children with frequently relapsing or steroid-dependent nephrotic syndrome. Methods: The clinical data of 38 children with frequently relapsing or steroid-dependent nephrotic syndrome who were admitted to the Department of Nephrology, the Children Hospital, Zhejiang University School of Medicine from January 2015 to December 2020 were retrospectively analyzed. The general information, clinical manifestations, laboratory data of the children and follow-up (till 12 months after treatment) were collected. The patients were divided into ACTH group and Glucocorticoid (GC) group according to treatment plan. Cumulative remission, average recurrence rate, GC dosage, height and weight change and peripheral blood CD19+B lymphocyte count were compared between the two groups to evaluate the efficacy and adverse reactions of ACTH. Fisher's exact test, t test or rank sum test was used for comparison between groups. Results: Among the 38 patients, 28 were male and 10 were female, aged 84 (24, 180) months; 19 were in ACTH group and 19 were in GC group. The cumulative remission rate of 12 months in ACTH group was higher than that in GC group (9/19 vs. 2/19,χ²=6.81,P=0.009), the average recurrence rate was lower than that in GC group ((0.7±0.8) vs. (1.7±1.1) times, t=-3.27, P=0.011), and the average dosage of GC was lower than that in GC group ((0.27±0.16) vs. (0.51±0.27) mg/(kg·d), t=-3.21, P=0.014). The increase in height was higher than that in the GC group (4 (3,5) vs. 3 (2, 3) cm/year, Z=2.58, P=0.010), and the peripheral blood CD19+B lymphocyte count was lower than that in the GC group ((223±149)×106 vs. (410±213)×106/L,t=-3.35, P=0.009). In safety, 19 cases had transient decreased urine volume, 7 cases had hyperglycemia, and 3 cases had hypertension during the infusion of ACTH, which could be relieved after drug withdrawal. Conclusion: ACTH has a better effect on children with frequently relapsing or steroid-dependent nephrotic syndrome, which can improve cumulative sustained remission rate, lower relapses rate and decrease the dosage of GC, with good safety.

ABSTRACT

Objective: To evaluate the efficacy and prognosis of basiliximab in the treatment of steroid-refractory or steroid-dependent acute graft-versus-host disease (SR/SD-aGVHD) after allogeneic hematopoietic stem cell transplantation (allo-HSCT) . Methods: Clinical data of 87 patients with SR/SD-aGVHD in the skin, intestine, and liver after allo-HSCT at the Institute of Hematology & Blood Diseases Hospital Transplantation Center from January 2015 to December 2018 were retrospectively analyzed. The administration plan of basiliximab was as follows: 20 mg for adults and children weighing ≥35 kg and 10 mg for children weighing<35 kg. The drug was administered once on the 1st, 4th, and 8th days, respectively, and then once weekly. The efficacy was evaluated on the 7th, 14th, 21st, and 28th days after basiliximab treatment. Results: ①There were 51 males (58.6%) and 36 females (41.4%) , with a median (range) age of 34 (4-63) years. There were 54 cases of classic aGVHD, 33 of late aGVHD, 49 of steroid-refractory aGVHD, and 38 of steroid-dependent aGVHD. ②Thirty-five patients (40.2%) achieved complete remission (CR) , 23 (26.4%) achieved partial remission (PR) , and 29 had no remission (NR) . The total effective rate[overall response rate (ORR) ] was 66.7% (58/87) . ③The ORR of the classic and late aGVHD groups was 77.8% (42/54) and 48.5% (16/33) , respectively. ④The median (range) follow-up time was 154 (4-1813) days, the 6-month overall survival (OS) rate of the 87 patients was 44.8% (95% CI 39.5%-50.1%) and the 1-year OS was 39.4% (95%CI 34.2%-44.3%) . ⑤After treatment with basiliximab, the 6-month OS in the CR (35 cases) , PR (23 cases) , and NR (29 cases) groups was 80.0% (95%CI 73.2%-86.8%) , 39.1% (95%CI 28.9%-49.3%) , and 6.9% (95%CI 2.2%-11.6%) , respectively (χ(2)=34.679, P<0.001) , and the 1-year OS was 74.3% (95%CI 66.9%-81.7%) , 30.4% (95%CI 20.8%-40.0%) , and 3.4% (95%CI 0%-6.8%) , respectively (χ(2)=43.339, P<0.001) . The OS of the classic and late aGVHD groups was 57.4% (95%CI 50.7%-64.1%) and 24.2% (95%CI 16.7%-31.7%) , respectively (χ(2)=9.109, P=0.004) , and the 1-year OS was 51.9% (95%CI 45.1%-58.7%) and 18.2% (95%CI 11.5%-24.9%) , respectively (χ(2)=9.753, P=0.003) . ⑥Univariate and multivariate analyses showed that late aGVHD (OR=3.121, 95%CI 1.770-5.503, P<0.001) , Minnesota score high-risk group before medication (OR=3.591, 95%CI 1.931-6.679, P<0.001) , active infection before medication (OR=1.881, 95%CI 1.029-3.438, P=0.040) , and impairment of important organ function caused by non-GVHD (OR=3.100, 95%CI 1.570-6.121, P=0.001) were independent risk factors affecting the efficacy of basiliximab. Conclusion: Basiliximab has good efficacy and safety for SR/SD-aGVHD, but not in patients with late aGVHD, high-risk group of Minnesota score, and infection or impaired function of important organs.

ABSTRACT

OBJECTIVE@#To analyze the kinetic characteristics of lymphocyte subsets and myeloid-derived suppressor cell (MDSC) in patients who newly diagnosed intermediate- to high-risk aGVHD and treated with steroids-ruxolitinib as the first line therapy from a single-arm, open clinical trial (NCT04061876).@*METHODS@#We prospectively observed the efficacy of 23 patients having intermediate- to high-risk aGVHD and treated with steroids-ruxolitinib as the first line therapy. The kinetic characteristics of lymphocyte subsets and MDSC were monitored, and then we compared them in steroids-ruxolitinib group (n=23), free-aGVHD group (n=20) and steroids group (n=23).@*RESULTS@#Of the 23 patients, the CR rate was 78.26% (18/23) on day 28 after first-line treatment with steroids-ruxolitinib. On day 28 after treatment, patients had lower level of CD4+CD29+ T cells (P=0.08) than that of pre-treatment, whereas levels of other lymphocyte subsets in this study were higher than that of pre-treatment; CD4+CD29+ T cells in CR patients decreased, compared with refractory aGVHD patients. On day 28 of treatment, CD8+CD28- T cells (P=0.03) significantly increased in patients with aGVHD than that in patients without aGVHD, so did CD8+CD28- T / CD8+CD28+ T cell ratio (P=0.03). Compared with patients without aGVHD, patients with aGVHD had lower level of G-MDSC, especially on day 14 after allo-HSCT (P=0.04). Compared with pre-treatment, M-MDSC was higher in CR patients on day 3 and 7 post-treatment (P3=0.01, P7=0.03), e-MDSC was higher on day 28 post-treatment (P=0.01). Moreover, compared with CR patients, M-MDSC was lower in refractory aGVHD patients on day 3 post-treatment (P=0.01) and e-MDSC was lower on day 28 post-treatment (P=0.01). Compared with steroids group, MDSC in steroids-ruxolitinib group was higher, with the most significant difference in M-MDSC (P3=0.0351; P7=0.0142; P14=0.0369).@*CONCLUSION@#We found that patients newly diagnosed intermediate- to high-risk aGVHD receiving first-line therapy with steroids-ruxolitinib achieved high response rate. Moreover, the novel first-line therapy has a small impact on the immune reconstitution of patients after allo-HSCT. Elevated MDSC might predict a better response in aGVHD patients receiving this novel first-line therapy. M-MDSC responded earlier to steroids-ruxolitinib than e-MDSC, G-MDSC.

ABSTRACT

El estudio tuvo como objetivo comparar el grupo de hidrodisección de solución salina normal guiada por ultrasonido más esteroides y el grupo de hidrodisección de solución salina normal guiada por ultrasonido sola en pacientes con síndrome del túnel carpiano (STC), y determinar su relevancia clínica en relación con los resultados del tratamiento. Realizamos 60 hidrodisecciones guiadas por ecografía con solución salina normal con y sin inyecciones de corticosteroides en 51 pacientes con STC y evaluamos los resultados de la ecografía antes y después de la inyección. Clasificamos estas inyecciones en dos grupos según la solución salina normal más corticosteroide (grupo de esteroides). solución salina normal (grupo de control) y también registramos datos clínicos que incluían el sexo, la edad, el lado de la inyección, el peso corporal y la duración de las molestias relacionadas con el STC antes de la inyección. Los resultados se midieron mediante la escala analógica visual que se asignó para evaluar el resultado primario. Los resultados secundarios se evaluaron mediante el cuestionario del síndrome del túnel carpiano de Boston, el área transversal del nervio mediano y estudios electrofisiológicos. La evaluación se realizó antes de la inyección y 1, 3 y 6 meses después de la inyección, y se comparó el alivio de los síntomas para los pacientes que recibieron la inyección de solución salina normal y de esteroides. Comparamos las hidrodisecciones con la solución salina normal y las inyecciones de corticosteroides. Los datos clínicos, las puntuaciones de CSA-MN antes de la inyección en la entrada del túnel carpiano y las puntuaciones de BCTQ antes de la inyección no mostraron diferencias significativas entre los grupos (p> 0,05). Todos los pacientes (datos de 30 muñecas en cada grupo) completaron el estudio. En comparación con el grupo de control, en todos los momentos posteriores a la inyección, ambos grupos tuvieron una reducción significativa del dolor y la discapacidad, una mejora en las medidas de respuesta electrofisiológica y una disminución del área transversal del nervio mediano. Nuestro estudio revela que la solución salina normal guiada por ecografía con y sin hidrodisección de corticosteroides tiene un efecto terapéutico en los pacientes con STC. Se demostró que la hidrodisección nerviosa es potencialmente beneficiosa para los pacientes con STC antes de la cirugía. La hidrodisección es un procedimiento simple y mínimamente invasivo que se puede realizar utilizando únicamente NS. Además, en comparación con la inyección a ciegas, la hidrodisección bajo guía ecográfica puede reducir las posibilidades de lesión nerviosa


The study aimed to compare Ultrasound-Guided Normal saline plus steroid hydrodissection group and Ultrasound-Guided normal saline alone hydrodissection group in patients with carpal tunnel syndrome (CTS), and to determine their clinical relevance in relation to treatment outcomes. We performed 60 US-guided hydrodissections Normal saline with and without corticosteroid injections in 51 patients with CTS and evaluated their pre- and post-injection US findings. We categorized these injections into two groups based on the normal saline plus corticosteroid (steroid group). normal saline (control group) and we also recorded clinical data including gender, age, side of injection, BW, and the duration of preinjection CTS related discomfort. The outcomes were measured using the visual analog scale was assigned to assess the primary outcome. The secondary outcomes were assessed using the Boston Carpal Tunnel Syndrome Questionnaire, cross-sectional area of the median nerve, and electrophysiological studies. The assessment was performed prior to injection, and 1-, 3-, and 6-months' post-injection, and the symptom relief for the patients receiving normal saline and steroid injection were compared. We compared hydrodissections with normal saline and corticosteroid injections The clinical data, pre injection CSA-MN at the inlet of the carpal tunnel, and pre-injection BCTQ scores showed no significant intergroup differences (p > 0.05). All patients (data from 30 wrists in each group) completed the study. Compared both the control group, at all post-injection time points, both groups had a significant reduction in pain and disability, improvement on electrophysiological response measures, and decreased cross-sectional area of the median nerve. Our study reveals that ultrasound-guided Normal saline with and without corticosteroid hydrodissection has therapeutic effect in patients CTS. Nerve hydrodissection was shown to be potentially beneficial for CTS patients' pre-surgery. Hydrodissection is a simple, minimally invasive procedure that can be performed using only NS. In addition, compared to blind injection, hydrodissection under ultrasound guidance can lower the chances of nerve injury

ABSTRACT

Resumen La leptospirosis es una de las zoonosis endémicas más importantes en el mundo con un aumento de la incidencia en los últimos años. En el personal militar podría ser catalogada como una enfermedad ocupacional dado sus actividades específicas en áreas rurales. Su presentación clínica es variable siendo en la mayoría de los casos una enfermedad febril autolimitada. De acuerdo con diversos factores dependientes del patógeno y del hospedero pueden presentarse manifestaciones severas de la enfermedad dentro de la cual destaca el compromiso pulmonar con una alta tasa de mortalidad. Existe evidencia del uso de esteroide sistémico como parte del tratamiento de esta complicación. Presentamos el caso de un paciente joven, militar, que debuta con síndrome de hemorragia alveolar difusa secundario a leptospirosis y presenta una excelente respuesta al tratamiento con altas dosis de metilprednisolona, con una discusión del proceso diagnóstico y aspectos fisiopatológicos de esta condición.


Leptospirosis is one of the most important endemic zoonoses in the world with an increase in incidence in recent years. In military personnel it could be classified as an occupational disease given their specific activities in rural areas. Its clinical presentation is variable being in most cases a self-limited febrile disease. According to various factors dependent on the pathogen and the host, severe manifestations of the disease may occur within which the pulmonary involvement with a high mortality rate stands out. There is evidence of systemic steroid use as part of the treatment of this complication. We present a case of a young, military patient who debuts with diffuse alveolar hemorrhage syndrome secondary to leptospirosis and presents an excellent response to treatment with high doses of methylprednisolone, with a discussion of the diagnostic process and pathophysiological aspects of this condition.

ABSTRACT

En los ámbitos científico e institucional existe controversia sobre el manejo idóneo de la bron- quiolitis en pacientes pediátricos. El objetivo de este trabajo es valorar el nivel de evidencia cientí- fica que existe sobre el manejo de la bronquiolitis para determinar si las recomendaciones actuales son o no adecuadas. Se realizó una revisión sis- temática de artículos científicos consultando di- versas bases de datos, sin restricción de fecha, en los idiomas español e inglés. Se incluyó literatura gris mediante búsqueda manual. No se hicieron restricciones respecto al tipo de estudio. Se re- visaron los resúmenes y en los casos necesarios los artículos completos, teniéndose en cuenta fi- nalmente todos los artículos que incluían apor- tes sobre el manejo adecuado de la bronquiolitis. Como resultado la mayoría de las recomenda- ciones realizadas por las sociedades fueron a tra- vés de guías de práctica clínica o artículos de opinión, concluyendo que no se cuenta con un esquema de tratamiento adecuado para tratar la bronquiolitis aguda, existiendo un manejo erróneo con el uso de esteroides y antibióticos, mientras que uno de los tratamiento más viables y costo efectivos queda en el olvido como es la solución hipertónica al 3%, la cual ha demostra- do reducción de la estancia hospitalaria...(AU)

ABSTRACT

Resumen El síndrome de DRESS (Reacción a drogas con eosinofilia y síntomas sistémicos) es una patología poco frecuente en Pediatría, descrita por primera vez en 1996, por Bocquet. Puede presentarse en un tiempo variable luego de exposición a algunos medicamentos, se caracteriza por fiebre, compromiso cutáneo y de órganos internos. En este caso, se presenta a un paciente de 13 años, con antecedente de uso de Trimetroprim sulfa desde hace 2 meses, con cuadro de 3 días consistente en fiebre y rash cutáneo, sin compromiso de mucosas, con respuesta no favorable al manejo con esteroide, requiriendo Inmunoglobulina IV. Semanas después del inicio de los síntomas y evolución estable presenta insuficiencia renal aguda que requirió terapia de reemplazo renal. Se descartaron otras patologías subyacentes de índole autoinmune. Hubo recuperación de azoados y normalización de los demás paraclínicos el día 40 de la enfermedad. El paciente continúa asintomático, 4 meses después, con tratamiento con esteroide oral, en descenso lento y gradual. Se debe considerar la evaluación permanente de las pruebas de función renal en los pacientes que presenten Síndrome de DRESS, por su asociación con Nefritis intersticial aguda y complicaciones relacionadas.


Abstract DRESS syndrome (Drug Reaction with Eosinophilia and Systemic Symptoms) is a rare pathology in Pediatrics, first described in 1996 by Bocquet. It can appear in a variable period of time after exposure to some medications, it is characterized by fever, skin involvement and internal organs. A 13-year-old patient is presented, with a history of use of Trimethoprim sulfa for two months, with a disease of three days of evolution, consisting of fever and skin rash, without mucosal involvement, with an unfavorable response to steroid management, requiring Intravenous inmunoglobulin. Weeks after the onset of symptoms and stable evolution, he presented acute renal failure that required renal replacement therapy. Other underlying autoimmune pathologies were ruled out. There was recovery of renal function test and normalization of the other paraclinical on day 40 of the disease. Patient remains asymptomatic four months later, with oral steroid treatment, in slow and gradual decline. Permanent evaluation of renal function tests should be considered in patients with DRESS syndrome, due to its association with acute tubulointerstitial nephritis and related complications.

ABSTRACT

RESUMEN El pseudotumor orbitario es la tercera causa de oftalmoplejía dolorosa; constituye un desafío diagnóstico pues obliga a descartar enfermedades de etiología muy diversa que lo provocan. Se presenta el caso de una paciente femenina, de color de piel blanca, de procedencia urbana, ama de casa, fumadora, que no practica ejercicios ni lleva dieta, con antecedentes de hipertensión arterial y artritis reumatoidea, que acudió al Servicio de Oftalmología por presentar síntomas inflamatorios anexiales: edema palpebral, quemosis conjuntival, vasos conjuntivales dilatados, que se acompañaban de proptosis, oftalmoplejía dolorosa con diplopía y de una masa tumoral palpable a nivel de la porción supero-externa de la órbita. Se ingresó y se le realizaron estudios imagenológicos e histológicos, que solo aportaron signos inflamatorios y una pansinusitis. Se concluyó como un pseudotumor orbitario en su forma aguda de aparición, asociada a la artritis reumatoidea, cuyo diagnóstico se realizó por exclusión sobre la base de los resultados negativos de los estudios imagenológicos y de la biopsia. Llevó tratamiento con antibióticos parenterales y altas dosis de esteroides orales con regresión del cuadro y mejoría clínica. Se decidió la presentación del caso porque en la provincia no existen reportes sobre esta entidad, y por el énfasis en cómo llegar al diagnóstico y su correcto manejo, evitando con ello secuelas en el órgano visual.


ABSTRACT Orbital pseudotumor is the third cause of painful ophthalmoplegia; it constitutes a diagnostic challenge as it forces us to rule out diseases of very diverse etiology that cause it. A female patient, of white skin color, of urban origin, housewife, smoker, who does not practice exercises or is not on a diet, with a history of high blood pressure and rheumatoid arthritis, who attended the Ophthalmology service for presenting Adnexal inflammatory symptoms: eyelid edema, conjunctival chemosis, dilated conjunctival vessels, which were accompanied by proptosis, painful ophthalmoplegia with diplopia and a palpable tumor mass at the level of the superior-external portion of the orbit was presented. She was admitted and imaging and histological studies were performed, which only revealed inflammatory signs and pansinusitis. It was concluded as an orbital pseudotumor in its acute onset form, associated with rheumatoid arthritis, the diagnosis of which was made by exclusion on the basis of the negative results of imaging studies and biopsy. She was treated with parenteral antibiotics and high doses of oral steroids with regression of the symptoms and clinical improvement. The presentation of the case was decided because in the province there are no reports on this entity, and because of the emphasis on how to reach the diagnosis and its correct management, thereby avoiding effects in the visual organ.

ABSTRACT

La enfermedad por el Coronavirus 2019 (COVID-19 - Coronavirus Disease 2019) es una patología respiratoria de humanos producida por la infección por un nuevo coronavirus identificado como el Síndrome Respiratorio Agudo Severo por Coronavirus 2 (SARS-CoV-2). 1 El 11 de marzo de 2020 la Organización Mundial de la Salud (OMS) declaro al COVID-19 como una pandemia, y desde ese momento hasta el 28 abril del 2021 se ha reportado aproximadamente para Argentina con más de 2.900.000 casos confirmados y 62.599 muertes. 1,2 Al no existir un tratamiento farmacológico específico contra el virus hasta el momento la comunidad científica ha actuado globalmente orientada al descubrimiento y desarrollo intervenciones antivirales y en resignificar diferentes tipos de fármacos que se utilizan en otras indicaciones. En este contexto, existirían evidencias sobre efectos de fármacos como la dexametasona en la reducción de la mortalidad en pacientes hospitalizados por COVID-19 con complicaciones respiratorias graves y que las heparinas son efectivas en la prevención de la trombosis venosa profunda también en casos graves. El presente informe pretende evaluar si el empleo de los esteroides es eficaz, seguro y resulta conveniente para el tratamiento de pacientes con COVID-19 en Argentina

Clasificamos estas inyecciones en dos grupos según la solución salina normal más corticosteroide (grupo de esteroides). solución salina normal (grupo de control) y también registramos datos clínicos que incluyen el sexo, la edad, el lado de la inyección, el peso corporal y la duración de las molestias relacionadas con el STC antes de la inyección. Los resultados se midieron mediante la escala analógica visual que se asignó para evaluar el resultado primario. Los resultados secundarios se evaluaron mediante el cuestionario del síndrome del túnel carpiano de Boston, el área transversal del nervio mediano y estudios electrofisiológicos. La evaluación se realizó antes de la inyección y 1, 3 y 6 meses después de la inyección, y se comparó el alivio de los síntomas de los pacientes que recibieron la inyección de solución salina normal y de esteroides. Comparamos las hidrodisecciones con la solución salina normal y las inyecciones de corticosteroides; los datos clínicos, la preinyección de CSA-MN en la entrada del túnel carpiano y las puntuaciones de BCTQ antes de la inyección no mostraron diferencias significativas entre los grupos (p> 0,05). Todos los pacientes (datos de 30 muñecas en cada grupo) completaron el estudio. En comparación con el grupo de control, en todos los momentos posteriores a la inyección, ambos grupos tuvieron una reducción significativa del dolor y la discapacidad, una mejoría en las medidas de respuesta electrofisiológica y una disminución del área transversal del nervio mediano. Nuestro estudio revela que la solución salina normal guiada por ecografía con y sin hidrodisección de corticosteroides tiene un efecto terapéutico en los pacientes con STC. Se demostró que la hidrodisección nerviosa es potencialmente beneficiosa para los pacientes con STC antes de la cirugía. La hidrodisección es un procedimiento simple y mínimamente invasivo que se puede realizar utilizando únicamente NS. Además, en comparación con la inyección a ciegas, la hidrodisección bajo guía ecográfica puede reducir las posibilidades de lesión nerviosa.


The study aimed to compare Ultrasound-Guided Normal saline plus steroid hydrodissection group and Ultrasound-Guided normal saline alone hydrodissection group in patients with carpal tunnel syndrome (CTS), and to determine their clinical relevance in relation to treatment outcomes. We performed 60 US-guided hydrodissections Normal saline with and without corticosteroid injections in 51 patients with CTS and evaluated their pre- and post-injection US findings. We categorized these injections into two groups based on the normal saline plus corticosteroid (steroid group). normal saline (control group) and we also recorded clinical data including gender, age, side of injection, BW, and the duration of pre-injection CTS related discomfort. The outcomes were measured using the visual analog scale was assigned to assess the primary outcome. The secondary outcomes were assessed using the Boston Carpal Tunnel Syndrome Questionnaire, cross-sectional area of the median nerve, and electrophysiological studies. The assessment was performed prior to injection, and 1, 3, and 6 months' post-injection, and the symptom relief for the patients receiving normal saline and steroid injection were compared. We compared hydrodissections with normal saline and corticosteroid injections the clinical data, pre injection CSA-MN at the inlet of the carpal tunnel, and pre-injection BCTQ scores showed no significant intergroup differences (p > 0.05). All patients (data from 30 wrists in each group) completed the study. Compared both the control group, at all post-injection time points, both groups had a significant reduction in pain and disability, improvement on electrophysiological response measures, and decreased cross-sectional area of the median nerve. Our study reveals that ultrasound-guided Normal saline with and without corticosteroid hydrodissection has therapeutic effect in patients CTS. Nerve hydrodissection was shown to be potentially beneficial for CTS patients' pre-surgery. Hydrodissection is a simple, minimally invasive procedure that can be performed using only NS. In addition, compared to blind injection, hydrodissection under ultrasound guidance can lower the chances of nerve injury.

ABSTRACT

Os esteroides anabólicos androgênicos (EAA) são utilizados clinicamente para tratar diferentes doenças, porém propagou-se o uso não terapêutico por atletas de elite e fisiculturistas, com o intuito de aumentar a massa muscular e melhorar o desempenho físico. O uso de substâncias ergogênicas, como fármacos estimulantes e narcóticos analgésicos no esporte, foi proibido em 1967 pelo International Olympic Committee (COI), mas somente em 1976 os EAA entraram para a lista de substâncias proibidas. O uso de EAA está associado a diversos efeitos adversos, principalmente cardiovasculares, neuroendócrinos e distúrbios psiquiátricos, além de dislipidemia, elevação dos marcadores inflamatórios e disfunção endotelial. As análises toxicológicas constam como a maneira mais eficaz de minimizar o doping no esporte. O material é fornecido pelo atleta durante as competições ou treinamentos e previne que os competidores alcancem vantagem competitiva devido ao uso de EAA. A utilização de métodos para amostragem alternativos tem ganhado força, devido à necessidade de técnicas mais práticas que utilizam pouco volume de amostra e possuem facilidade de armazenamento. O dried urine spots é um método no qual pequenas amostras de urina são aplicadas em papéis de filtro para análises qualitativas ou quantitativas. Ele se caracteriza por ser uma técnica rápida, fácil, simples e barata para a coleta, armazenamento e distribuição, além de minimizar os riscos de infecção, podendo ser utilizado na rotina. A técnica de paper spray (PS-MS) foi desenvolvida a partir da relevância de métodos como o dried blood spots por proporcionar análises mais rápidas, apresenta alta especificidade, capacidade de analisar diferentes analitos simultaneamente, baixo limite de detecção e dispensa a necessidade de reagentes específicos. Sendo assim, neste trabalho foi desenvolvido e validado o método de screening de EAAs em dried urine spots por ionização por paper spray acoplada à espectrometria de massas. O método apresentou limites de detecção entre 2-15ng/mL e presença de três interferentes endógenos. Os dez analitos de interesse deste estudo são estáveis por 150 dias em temperatura ambiente. Dessa forma, a análise de EAAs em dried urine spots por PS-MS demonstra grande potencial para se tornar um método alternativo no monitoramento rápido de drogas de abuso


Anabolic androgenic steroids (AAS) are used clinically to treat different diseases, but non-therapeutic use has spread among elite athletes and bodybuilders, with the aim of increase muscle mass and improve physical performance. The International Olympic Committee (IOC) banned the use of ergogenic substances, such as stimulating drugs and analgesic narcotics in sports, in 1967, but only in 1976, AAS were included on the list of prohibited substances. The use of AAS is associated with several adverse effects, mainly cardiovascular, neuroendocrine and psychiatric disorders, in addition to dyslipidemia, elevated inflammatory markers and endothelial dysfunction. Toxicological analyzes are the most effective approach to minimize doping in sport. The material is provided by the athlete during competitions or training and prevents competitors from achieving a competitive advantage due to the use of AAs. The use of alternative sampling methods has gained strength, due to the need for more practical techniques that use low sample volume and can be easily storage. Dried urine spots are a method, which a small amount of urine samples is applied to filter papers for qualitative or quantitative analysis. It is characterized by being a fast, easy, simple and inexpensive technique for collection, storage and distribution, in addition to minimizing the risks of infection, and can be used in the routine. The paper spray technique (PS-MS) was developed based on the relevance of methods such as dried blood spots for providing faster analysis, high specificity, ability to analyze different analytes simultaneously, low detection limit and for eliminating the need for specific reagents. Therefore, this work developed and validated a screening method for AAS in dried urine spots by paper spray-mass spectrometry ionization. The method provided detection limits between 2-15ng/mL and the presence of three endogenous interferents. The ten analytes of interest in this study are stable for 150 days at room temperature. Thus, the analysis of AAS in dried urine spots by PS-MS demonstrates great potential to become an alternative method for the rapid monitoring of drugs of abuse
