Pregnancy-associated neuromyelitis optical spectrum disorder combined with primary Sjögren's syndrome: A critical illness case report / 北京大学学报(医学版)

Central nervous system involvement in primary Sjögren's syndrome (pSS) is less common and usually presents as white matter lesions, neuromyelitis optica spectrum disorder (NMOSD), or transverse myelitis. NMOSD is an immune-mediated inflammatory demyelinating disease of the central nervous system with a high rate of relapse and significant disability. Studies have shown that patients with pSS combined with NMOSD have more severe symptoms and poorer prognosis. Here, we present a case of critical illness in pregnancy-associated NMOSD combined with Sjögren's syndrome. The patient was a 30-year-old pregnant woman with a history of Sjögren's syndrome who was diagnosed with NMOSD. She received combination therapy with steroids, intravenous immunoglobulin (IVIG), and hydroxychloroquine during pregnancy, resulting in partial resolution of numbness below the waist. However, due to irregular medication adherence outside the hospital setting, she developed weakness in her right lower limb accompanied by inability to move it, while her left lower limb still had some mobility but occasional numbness along with urinary and fecal incontinence. Ten days later, she was admitted to the emergency department where an emergency cesarean section was performed to deliver a healthy baby boy. However, her condition worsened postpartum as she developed high fever accompanied by bilateral lower limb paralysis and weakness along with loss of voluntary control over urination and defecation. The patient underwent ano-ther course of treatment consisting of steroids and IVIG; however there was limited improvement in symptoms observed after this intervention. Following administration of rituximab for the first time, the patient developed urinary tract infection which was successfully managed before continuing regular infusions. In later stages the patient could walk slightly with a limp and regained control over urination and defecation, allowing her to resume normal activities. This case suggests that combination therapy with steroids, IVIG, and hydroxychloroquine should be considered for the patients with pregnancy-associated NMOSD combined with Sjögren's syndrome. Rituximab can significantly improve symptoms such as postpartum paralysis in patients with NMOSD, however, there may be a risk of infection associated with its use.

A control study of steroid withdrawal protection strategy after kidney transplantation in children / 中华儿科杂志

Objective: To study the influence of steroid withdrawal protection strategy on height growth in pediatric patients after kidney transplantation. Methods: The prospective cohort study enrolled 40 stage 5 chronic kidney disease children receiving kidney transplantation from July 2017 to September 2022 at Guangzhou Women and Children's Medical Center. Based on the primary preoperative disease, patients with immune abnormality-associated glomerular diseases or unknown causes were assigned to the steroid maintenance group, in which patients received steroid tapering within 3 months after surgery to a maintenance dose of 2.5 to 5.0 mg/d. While patients with hereditary kidney disease or congenital urinary malformations were assigned to the steroid withdrawal group, in which patients had steroids tapered off within 3 months. The characteristics of height catch-up growth and clinical data were compared between the 2 groups at baseline, 6, 12, 18 and 24 months after kidney transplantation. T-test, repeated measurement of variance analysis, Mann-Whitney U test, and Fisher exact test were used for the comparison between the 2 groups. Results: Among the 40 children, 17 were males, 23 were females, 25 were in the steroid withdraw group ((7.8±2.8) years old when receiving kidney transplantation) and 15 cases were in the steroid maintenance group ((7.6±3.5) years old when receiving kidney transplantation). The study population was followed up for (26±12) months. The total dose per unit body weight of steroids in the steroid withdrawal group was lower than that in the steroid maintenance group ((0.13±0.06) vs. (0.36±0.19) mg/(kg·d), t=5.83, P<0.001). The height catch-up rate (ΔHtSDS) in the first year after kidney transplantation in the steroid withdraw and steroid maintenance groups was 1.0 (0.7, 1.4) and 0.4 (0.1, 1.0), respectively; in the second year, the ΔHtSDS in the steroid withdraw group was significantly higher than that in the steroid maintenance group (1.1 (0.2, 1.7) vs. 0.3 (0, 0.8), U=28.00, P=0.039). The HtSDS in the steroid withdrawal group at the five follow-up time points was -2.5±0.8, -2.0±0.8, -1.5±0.8, -1.3±0.9 and -0.5±0.3, respectively, while in the steroid maintenance was -2.4±1.3, -2.2±1.1, -2.0±1.0, -1.8±1.0 and -1.6±1.0, respectively. There were statistically significant differences in HtSDS at different follow-up time points in both 2 groups (F=19.81, P<0.01), but no statistical differences in overall impact between the 2 groups (F=1.13, P=0.204). The steroid treatment was interaction with the increase of follow-up time (F=3.62, P=0.009). At the 24th month after transplantation, the HtSDS in the steroid withdrawal group was significantly higher than that in the steroid maintenance group (P=0.047). Six patients in the steroid withdrawal group experienced antibody-mediated immune rejection (AMR), while 3 did in the steroid maintenance group. Moreover, there was no significant difference in AMR between the two groups (χ2=0.06, P=0.814). Conclusion: The steroid withdrawal protection strategy favors the height catch-up growth in pediatric patients after kidney transplantation and does not increase the risk of postoperative antibody-mediated immune rejection.

Establishment and validation of clinical prediction model for steroid-resistant nephrotic syndrome in children / 中华儿科杂志

Objective: To identify the clinically relevant factors of steroid-resistant nephrotic syndrome (SSNS) in children and establish a predictive model followed by verifying its feasibility. Methods: A retrospective analysis was performed in a total of 111 children with nephrotic syndrome admitted to Children's Hospital of ShanXi from January 2016 to December 2021. The clinical data of general conditions, manifestations, laboratory tests, treatment, and prognosis were collected. According to the steroid response, patients were divided into SSNS and steroid resistant nephrotic syndrome (SRNS) group. Single factor Logistic regression analysis was used for comparison between the 2 groups, and variables with statistically significant differences were included in multivariate Logistic regression analysis. The multivariate Logistic regression analysis was used to identify the related variables of children with SRNS. The area under the receiver operating characteristic curve (ROC), the calibration curve and the clinical decision curve were used to evaluate its effectiveness of the variables. Results: Totally 111 children with nephrotic syndrome was composed of 66 boys and 45 girls, aged 3.2 (2.0, 6.6) years. There were 65 patients in the SSNS group and 46 in the SRNS group.Univariate Logistic regression analysis showed that the 6 variables, including erythrocyte sedimentation rate, 25-hydroxyvitamin D, suppressor T cells, D-dimer, fibrin degradation products, β2-microglobulin, had statistically significant differences between SSNS and SRNS groups (85 (52, 104) vs. 105 (85, 120) mm/1 h, 18 (12, 39) vs. 16 (12, 25) nmol/L, 0.23 (0.19, 0.27) vs. 0.25 (0.20, 0.31), 0.7 (0.6, 1.1) vs. 1.1 (0.9, 1.7) g/L, 3.1 (2.3, 4.1) vs. 3.3 (2.7, 5.8) g/L, 2.3 (1.9,2.8) vs. 3.0 (2.5, 3.7) g/L, χ2=3.73, -2.42, 2.24, 3.38, 2.24,3.93,all P<0.05), were included in the multivariate Logistic regression analysis. Finally, we found that 4 variables including erythrocyte sedimentation rate, suppressor T cells, D-dimer and β2-microglobulin (OR=1.02, 1.12, 25.61, 3.38, 95%CI 1.00-1.04, 1.03-1.22, 1.92-341.04, 1.65-6.94, all P<0.05) had significant correlation with SRNS. The optimal prediction model was selected. The ROC curve cut-off=0.38, with the sensitivity of 0.83, the specificity of 0.77 and area under curve of 0.87. The calibration curve showed that the predicted probability of SRNS group occurrence was in good agreement with the actual occurrence probability, χ2=9.12, P=0.426. The clinical decision curve showed good clinical applicability. The net benefit is up to 0.2. Make the nomogram. Conclusions: The prediction model based on the 4 identified risk factors including erythrocyte sedimentation rate, suppressor T cells, D-dimer and β2-microglobulin was suitable for the early diagnosis and prediction of SRNS in children. The prediction effect was promising in clinical application.

Arteritis de células gigantes: ¿Cómo debutan pacientes chilenos? Análisis de casos y revisión de la literatura / Giant cell arteritis. Experience in 32 patients

BACKGROUND: Giant cell Arteritis (GCA) is the most common systemic vasculitis in patients over 50 years. Diagnosis is based on clinical, laboratory, imaging and biopsy. Temporal artery biopsy (TAB) may be inconclusive in up to 40% of patients. AIM: To describe disease features of patients diagnosed with GCA. MATERIAL AND METHODS: Review of pathology reports of giant cell arteritis and clinical records of patients seen with the diagnosis between 2000 and 2019. Demographic, clinical, laboratory, histopathology, imaging, treatment and follow-up variables were analyzed. RESULTS: We fetched 32 patients with a median age at diagnosis of 70.5 years (range 57-90), 81% women. Twenty eight percent had polymyalgia. 72% had only cranial symptoms, 12% had extracranial involvement and 13% exclusive extracranial involvement. The median time from onset of symptoms to diagnosis was two months (range 0.5-8). All had elevated erythrocyte sedimentation rate and c reactive protein. A TAB was performed in 27 patients and in 17 (65.4%) it confirmed the diagnosis. Transmural inflam- mation was the most frequent finding. All patients received steroids. Follow-up information was available from 25 patients and 92% received a steroid-spa- ring agent, usually methotrexate (74%). Ninety two percent achieved clinical remission in the first year and 59% had minor relapses during steroid tapering. CONCLUSIONS: Our patients showed frequent extracranial involvement and TAB was a useful diagnostic tool.

Directrices para el diagnóstico clínico y el tratamiento del Dengue, el Chikunguña y el Zika / Guidelines for the clinical diagnosis and treatment of Dengue, Chikungunya, and Zika

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.

Efficacy of basiliximab in the treatment of 87 cases of steroid-refractory or steroid-dependent acute graft-versus-host disease / 中华血液学杂志

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.

Hidrodisección guiada por ultrasonido para el tratamiento de pacientes con sindrome del tunel carpiano / Ultrasound-Guided hydrodissection for treatment of Patients with Carpal Tunnel Syndrome

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

Hemorragia alveolar pulmonar como presentación poco frecuente de infección por Leptospira spp: una enfermedad ocupacional del personal militar en zonas tropicales / Pulmonary alveolar hemorrhage as an unusual presentation of Leptospira spp: an occupational-disease of military personnel in tropical zones

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.

Enfermedad inflamatoria orbitaria idiopática. Presentación de un caso / Idiopathic orbital inflammatory disease. Case presentation

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.

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.

Introducción: El dolor lumbar es uno de los principales motivos de consulta en diferentes escenarios clínicos; entre las causas más frecuentes de dolor lumbar se encuentra el canal lumbar estrecho, discopatía y radiculopatías, por lo que se han establecido diferentes modalidades de tratamiento que incluyen medidas invasivas, como las inyecciones de esteroides epidurales vía caudal. Objetivo: Evaluar la mejoría del dolor lumbar después de la aplicación de esteroides epidurales caudales no particulados en la población con dolor crónico lumbar bajo secundario a canal lumbar estrecho, discopatía y radiculopatía lumbar de un hospital en Bogotá, Colombia. Metodología: Se realizó un estudio observacional retrospectivo en el que se evaluó la reducción del dolor, en pacientes con diagnóstico de dolor lumbar crónico secundario a canal lumbar estrecho, radiculopatía, discopatía, mediante escala visualanáloga del dolor EVA seis meses después de la aplicación de dexametasona 8 mg vía epidural caudal en 147 pacientes en un período de 2 años. Resultados: Se evaluaron 147 pacientes con dolor lumbar crónico, de los cuales 58.32% eran mujeres y 47.76% hombres, con edades entre 44 y 77 años, de los cuales 50% eran mayores o igual a 65 años y 75% mayor o igual a 77 años. En la evaluación inicial del dolor lumbar, se encontró que el 50% de los pacientes tenían una EVA inicial mayor o igual a 8/10 y el 75% informó un EVA inicial 10/10. Se encontró que el canal lumbar estrecho fue la principal causa de dolor lumbar en el 53,06% de los pacientes, seguido de la enfermedad del disco lumbar el 49,66% y en el tercer lugar, los pacientes con radiculopatía lumbar correspondieron al 19.73% de la población. Sobre la mejoría del dolor de una manera particular, se encontró una mayor reducción del dolor en pacientes con enfermedad de disco lumbar 48,21%, seguido de estrecho canal lumbar estrecho 41,37% y radiculopatías lumbares 33,3%. En el análisis comparativo por patología aislada, la intervención no presentó una mejora considerable, sin embargo, cuando más de una de las entidades estudiadas coexistieron en el mismo paciente, hubo una mejoría significativa del dolor, por lo que en el 66,5% de los pacientes diagnosticados con un canal lumbar estrecho y radiculopatía, la mejoría de la lumbalgia y la radiculopatía disminuyó, de la misma forma que los pacientes que presentaron discopatía y radiculopatía tuvieron un alivio del dolor del 66% y, finalmente, aquellos con discopatía y canal lumbar estrecho, 60% tuvieron una reducción del dolor después del procedimiento. Conclusión: La aplicación de esteroides no particulados vía epidural caudal proporciona una mejora sintomática significativa en un porcentaje considerable de pacientes sometidos al procedimiento, especialmente en aquellos que tienen más de una de las causas de dolor lumbar crónico expuesta, por lo que se constituye en una medida invasiva de tratamiento efectivo para el dolor lumbar en este tipo de pacientes.

Introduction: Low back pain is one of the main reasons for consultation in different clinical scenarios; among the most frequent causes of low back pain is the narrow lumbar canal, discopathy and radiculopathies, which is why different modalities have been established of treatment including invasive measures such as injections of epidural steroids caudal via. Objective: To evaluate the improvement of lumbar pain after application of non-particulate caudal epidural steroid via in the population with chronic low lumbar pain in the narrow lumbar canal, discopathy and lumbar radiculopathy of a military hospital in Bogotá, Colombia. Methodology: A retrospective observational study was performed in which the pain reduction measured by visual analogous scale of pain VAS was evaluated six months after the application of dexamethasone 8 mg caudal epidural via in 147 patients in a period of 2 years Results: 147 patients with chronic low back pain were evaluated, of which 58.32% were women and 47.76% men, with ages between 44 and 77 years, of which 50% were greater than or equal to 65 years and 75 % greater than or equal to 77 years. Concerning the initial evaluation of lumbar pain, it was found that 50% of the patients had an initial VAS greater than or equal to 8/10 and 75% reported an initial VAS 10/10. Regarding the prevalence of causes of low back pain in the evaluated patients, it was found that the narrow lumbar canal was the main cause in 53.06% of the patients, followed by lumbar disc disease 49.66% and in the third place patients with lumbar radiculopathy corresponded 19.73% of the population. About pain improvement in a particular way, greater pain reduction was found in patients with lumbar disc disease 48.21%, followed by narrow lumbar canal 41.37% and lumbar radiculopathies 33.3%. In the comparative analysis due to isolated pathology, the intervention did not present a considerable improvement, however, when more than one of the entities studied coexisted in the same patient, there was a significant improvement in pain, thus 66.5% of the patients diagnosed with a canal. Narrow lumbar and radiculopathy improved, in the same way those patients who presented with discopathy and radiculopathy 66% had relief of pain and finally those with discopathy and narrow lumbar canal 60% had pain reduction after the procedure. Conclusion: The application of non-particulate steroid via caudal epidural provides significant symptomatic improvement in a considerable percentage of patients undergoing the procedure, especially in those who have more than one of the causes of chronic low back pain exposed and evaluated, thus being able to constitute an invasive measure of effective treatment for low back pain in this type of patients.

Schistosomal myeloradiculopathy in a non-endemic area / Mielorradiculopatia esquistossomótica em região não endêmica

ABSTRACT Objective: To report a schistosomal myeloradiculopathy case in a non-endemic area. Case description: A previously healthy 11-year-old boy, stricken by an acute loss of strength on his lower limbs, followed by a loss of strength on his upper limbs and upper body, associated with altered sensitivity of the vesical globe formation. The patient's cerebrospinal fluid analysis showed eosinophilic meningitis, in addition to peripheral eosinophilia. The investigation resulted in a positive serology for Schistosoma mansoni. The treatment included steroids and praziquantel 60mg/kg, with a new dose after a month, as well as physical therapy for rehabilitation. The patient evolved with clinical improvement in the neurological exam, with a medullary section initially at C6, but now at T6. The patient is kept at prednisolone use (30mg/day) and longterm urinary catheter dependence. Comments: The schistosomiasis is endemic in many regions of Brazil; however, it has low incidence in the south of the country. Among its main manifestations, the schistosomal myeloradiculopathy is the most severe ectopic form of the disease, and should be suspected in patients with low back pain, strength and/or sensibility disorder of the lower limbs or urinary tract's disturbance. Early diagnosis and treatment should be done in order to reduce severe neurological sequelae. Treatment includes schistosomiasis drugs, corticosteroids and/or surgery.

RESUMO Objetivo: Relatar um caso de mielorradiculopatia esquistossomótica em área não endêmica. Descrição do caso: Paciente do sexo masculino, 11 anos, previamente hígido, com história aguda de paresia de membros inferiores, que evoluiu para membros superiores e tronco, associada à alteração de sensibilidade e formação de globo vesical. O exame do líquor demonstrava meningite eosinofílica, além de eosinofilia periférica. A investigação resultou em sorologia positiva para Schistosoma mansoni. O tratamento foi realizado com corticoterapia e praziquantel 60 mg/kg, com nova dose após um mês, além de fisioterapia para reabilitação. Evoluiu com melhora clínica no exame neurológico, com nível de secção medular que inicialmente correspondia a C6, encontrando-se atualmente em T6. Mantém uso de prednisolona 30 mg/dia e dependência de sonda vesical de demora. Comentários: A esquistossomose é uma doença endêmica em muitas regiões do Brasil, porém com pouca incidência no Sul do país. Dentre as principais manifestações, a mielorradiculopatia esquistossomótica é a forma ectópica mais grave e deve ser suspeitada na vigência de dor lombar, alteração de força e/ ou sensibilidade de membros inferiores e distúrbio urinário. O diagnóstico e o tratamento devem ser instituídos precocemente para diminuir o risco de sequelas neurológicas graves. O tratamento pode ser realizado com esquistossomicidas, corticosteroides e/ ou cirurgia.

Utility of Hyperbaric Oxygen Therapy for Acute Acoustic Trauma: 20 years' Experience at the Japan Maritime Self-Defense Force Undersea Medical Center

Introduction: Acute acoustic trauma, which is a kind of sensorineural hearing loss, is caused by acoustic overstimulation. Hyperbaric oxygen therapy (HBOT) is reported to be effective against acute acoustic trauma. Objective: We aimed to evaluate the efficacy of HBOT against acoustic hearing loss based on our 20 years of experience with such cases. Methods: Patients who were treated with HBOT for acute acoustic trauma between April 1997 and August 2017 were evaluated in this study. Thirty-five patients with a mean age of 25.7 ± 9.2 (range: 16­48) years were included. Thirty-nine out of 70 ears (35 patients) were damaged. We investigated the initial level of hearing loss; the extent to which hearing recovered; subjective symptoms, such as tinnitus and aural fullness; and the treatment administered. Results: The planned HBOT was completed in 37 of 39 ears. Twenty-six of the 37 ears (70.2%) displayed improved hearing, and 31 of the 37 ears (83.9%) exhibited symptom improvement. Twenty-three (76.7%) and 26 (86.7%) of the 30 ears treated with steroids demonstrated improvements in hearing and subjective symptoms, respectively. Conclusion: A combination of HBOT and steroids should be considered as a treatment for acute acoustic trauma in cases involving symptoms such as tinnitus and aural fullness (AU)
