[Thermal radiofrequency of the medial genicular nerves in chronic pain related to degenerative meniscopathy. A clinical case]. / Radiofrecuencia térmica de las ramas geniculares mediales para dolor crónico en contexto de meniscopatía degenerativa. A propósito de un caso.

Persistent knee pain in patients around the fifth decade of life is a frequent cause of attention in rehabilitation consultations. The most common cause of diagnosis is knee osteoarthritis, considering the existence of different degrees seen in simple radiographies. The advanced degrees present joint space reduction, osteophytosis and subchondral sclerosis; however, in the initial degrees, the findings are more subtle and sometimes nonexistent for conventional radiology. Clinical ultrasound has partly come to fill this «diagnostic gap¼, making it possible to detect meniscal extrusions and small osteophytes as signs of incipient osteoarthritis and to relate them as triggers of pain. In clinical practice we find a group of patients who, with little or no radiological alterations, present persistent and severe pain with medial predominance in most cases. These, until the appearance of the current evidence, were subsidiaries of meniscectomies. At this moment, when meniscectomies are not recommended, it is necessary to find a treatment for those cases in which conservative and non-ablative interventional treatment has failed. In this context, the possibility of using radiofrequency arises. Its use is widespread in the case of tricompartmental and advanced osteoarthritis. However, little data is available on its usefulness in cases of medial meniscal extrusion. It seems that thermal radiofrequency has greater effects than pulsed radiofrequency. We present a clinical case where thermal radiofrequency of the medial genicular nerves of the knee is proposed as a therapeutic alternative for chronic pain secondary to medial meniscal extrusion associated with incipient knee osteoarthritis, with the result of a decrease in pain (VAS 8 before treatment, VAS 1 after one year), subjective improvement of 80% and gait capacity.

Morphofunctional evaluation of peripapillary retinoschisis associated with myopic posterior staphyloma and hyaloid traction: does it cause peripapillary vitreoretinal traction? / Avaliação morfofuncional da retinosquise peripapilar associada ao estafloma posterior miópico e à tração hialoidea: isso causa tração vitreo-retiniana peripapilar?

ABSTRACT This case report presents the details of a 33-year-old female patient who was referred to a specialized retina service because of mild vision loss in her right eye). The patient's visual acuity was 20/25 in right eye and 20/50 in the left eye (; amblyopic); the spherical equivalent was -12.75 diopters (right eye) and -14.75 diopters (left eye). Multimodal retinal imaging showed peripapillary schisis in both the inner and outer retinal layers, grade II posterior vitreous detachment, and a tessellated fundus. Using Humphrey perimetry and MP-3 microperimetry, the functional evaluation indicated macular sensitivity within normal limits and decreased sensitivity in the peripapillary region, especially in right eye. The pattern-re versal visual evoked potential was measured. The N75 and P100 latency and amplitude in right eye were within normal values for checks of 1º. However, the amplitude was low for checks of 15′. Highly myopic patients who have posterior staphyloma that involves the optic nerve are susceptible to posterior hyaloid traction, and the resulting peripapillary vitreous traction may compromise vision.

RESUMO Este relato de caso apresenta um paciente feminino de 33 anos encaminhado para um serviço especializado de retina devido à leve perda de visão em olho direito. A acuidade visual foi de 20/25 no olho direito e 20/50 no olho esquerdo, o equivalente esférico foi de -12,75 dioptrias e -14,75 dioptrias, respectivamente. Avaliações multimodais revelaram isquese peripapilar nas camadas internas e externas da retina, descolamento vítreo posterior grau II e fundo tesselado. Avaliação funcional com perimetria Humphrey e microperimetria MP-3 revelaram sensibilidade macular normais e diminuição da sensibilidade na região peripapilar, especialmente no olho direito. Potencial visual evocado de padrão reverso apresentou no olho direito latência e amplitude N75 e P100 dentro dos valores normais para verificação de 1º. Entretanto, a amplitude foi baixa para a de 15′. Pacientes alto míopes com esfiloma posterior envolvendo o nervo óptico são suscetíveis à tração da hialoide posterior. Portanto a tração vitreopapilar resultante pode causar comprometimento da visão.

Percutaneous lumbar discectomy: a systematic review / Discectomia percutânea lombar: uma revisão sistemática

Introduction: Low back pain is a clinical condition with a multifactorial etiopathogenesis, which has a high socioeconomic impact, especially in the economically active population, as it is associated with frequent absenteeism and reduced quality of life. Through intervertebral disc degeneration, a progressive instability of the compromised region is observed, triggering a harmful positive feedback mechanism that further promotes intervertebral disc disease. Built by the interaction between the predisposing biopsychosocial components, a multidisciplinary therapeutic proposition is suggested. In persistent low back pain, treatment involves surgical procedures such as Percutaneous Lumbar Discectomy. Objectives: to evaluate the scientific evidence regarding the clinical outcomes and safety of this surgery. Method: systematic review duly registered in Prospero (CRD42022370811), based on the PICOD question, elaborated from a Boolean search in different databases for scientific articles, evaluated and selected in a paired way based on the eligibility criteria. In addition to extracting data related to the proposed objectives, the articles included were evaluated in relation to their level of evidence and strength of recommendation. Results: among the 12 articles included, it was observed that it is a clinically effective and safe procedure. In the set of evidences gathered, they are of high and moderate level of evidence with respective strength of recommendation strong/good and weak/moderate. Conclusion: Percutaneous Lumbar Discectomy promotes significant reduction of pain and increase in body functionality, in addition to preserving local musculoskeletal structures and preventing post-surgical joint instability. It is, therefore, a safe and clinically effective minimally invasive procedure for patients with herniated discs.

Introdução: a lombalgia é uma condição clínica de etiopatogenia multifatorial, que desencadeia um elevado impacto socioeconômico especialmente na população economicamente ativa, por associar-se ao absenteísmo frequente e à redução da qualidade de vida. Observa-se mediante a degeneração do disco intervertebral, uma instabilidade progressiva da região comprometida desencadeando um mecanismo de feedback positivo prejudicial que promove ainda mais a doença do disco intervertebral. Edificada pela interação entre os componentes biopsicossocial predisponentes, sugere-se uma proposição terapêutica multidisciplinar. Na dor lombar persistente o tratamento envolve procedimentos cirúrgicos como a Discectomia Percutânea Lombar. Objetivo: avaliar as evidencias científicas relativas aos desfechos clínicos e à segurança desta cirurgia. Método: revisão sistemática devidamente registrada no Prospero (CRD42022370811), fundamentada na pergunta PICOD acrônimo para Paciente, Intervenção, Comparação, Desfechos (outcomes) e Design, elaborada a partir de busca booleana em diferentes bases de dados por artigos científicos, avaliados e selecionados de forma pareado com base nos critérios de elegibilidade. Além da extração de dados relativos aos objetivos propostos, os artigos incluídos foram avaliados em relação ao respectivo nível de evidencia e força de recomendação. Resultados: dentre os 12 artigos incluídos, observou-se que se trata de um procedimento clinicamente efetivo e seguro. No conjunto de evidencias reunidas são de alto e moderado nível de evidencia com respectiva força de recomendação forte/boa e, fraca/moderada. Conclusão: a Discectomia Percutânea Lombar promove relevante redução da dor e aumento da funcionalidade corporal, além de preservar as estruturas musculoesqueléticas locais e prevenir a instabilidade articular pós-cirúrgica. Trata-se, portanto, de um procedimento minimamente invasivo seguro e clinicamente efetivo para os pacientes portadores de hérnia discal.

ABSTRACT: Objective: Evaluate the epidemiological and radiographic data of patients submitted to the Anterior Lumbar Interbody Fusion (ALIF) technique and the possible complications related to this procedure. Methods: A longitudinal and retrospective study was carried out to analyze electronic medical records and image files of patients who underwent spinal surgery using the ALIF technique between February 2019 and January 2021. Epidemiological data such as age, gender, and level of surgery were analyzed. Radiographic evaluations of lumbar lordosis from L1 to S1 were performed using the COBB technique and the anterior and posterior height of the disc space. The presence of intraoperative and postoperative complications in the patients was analyzed. Results: Initially, 70 patients were analyzed. The most prevalent operated level was L5-S1. The length of stay of the patients varied between 36 and 72 hours. Intraoperative bleeding ranged from 20mL to 400mL. Three patients had significant venous lesions. Differences between anterior and posterior lordosis and height measurements were significant (p < 0.001). Lordosis had a mean increase of 10.3°, anterior height had a mean increase of 7.9mm, and posterior height of 4.0mm. Six cases of intra and postoperative complications were observed. Conclusion: The patients showed improvement in the radiological parameters of the anterior and posterior height of the vertebral discs, with a significant increase in lumbar lordosis. Complication rates were 9.8%, and we had a short hospital stay. Level of Evidence II; Retrospective Longitudinal Study.

Tratamiento de la mielopatía cervical mediante abordaje posterior: laminoplastia vs. laminectomía con fijación posterior. ¿Existen diferencias desde el punto de vista clínico y radiológico? / Treatment of cervical myelopathy by posterior approach: Laminoplasty vs. laminectomy with posterior fixation, are there differences from a clinical and radiological point of view?

Introducción La mielopatía cervical degenerativa representa una entidad patológica producida por la estenosis del canal medular cervical, resultando en una compresión crónica de la médula espinal, variable y progresiva. El abordaje quirúrgico de la columna cervical puede realizarse por vía anterior y/o vía posterior. Respecto al abordaje posterior, existen 2 técnicas fundamentales: laminoplastia y laminectomía con fijación posterior (LFP). En la literatura actual existe controversia acerca de cuál de las 2 técnicas permite obtener mejores resultados postoperatorios. El objetivo es el estudio de las diferencias entre laminoplastia y LFP desde el punto de vista clínico y radiológico. Materiales y métodosSe realiza un estudio de una cohorte histórica de 39 pacientes (12 LFP y 27 laminoplastia) intervenidos en un período de 10 años en el Hospital Universitario La Paz con un seguimiento de 12 meses tras la cirugía. Se analizan y comparan los resultados clínicos mediante la escala de Nurick y la Escala Japanese Orthopaedic Association modificada (mJOA) y los resultados radiológicos mediante el ángulo de Cobb, eje sagital vertical, T1 Slope y el alineamiento (medido mediante Cobb-T1 Sloppe). Resultados Se observan diferencias significativas en la mejoría postoperatoria de la escala Nurick (p=0,008) y mJOA (p=0,018) en el grupo de laminoplastia. En LFP se objetiva una tendencia a una mejoría mayor, pero no se alcanza la significación estadística debido al bajo tamaño muestral de este grupo. No se objetivan diferencias estadísticamente significativas en cuanto a la variables radiológicas. Respecto al total de complicaciones, se observó un número mayor en el grupo de laminoplastia (7 casos) frente a LFP (un caso), pero no se vieron diferencias estadísticamente significativas... (AU)

Introduction Cervical degenerative myelopathy is a variable and progressive degenerative disease caused by chronic compression of the spinal cord. Surgical approaches for the cervical spine can be performed anteriorly and/or posteriorly. Regarding the posterior approach, there are 2 fundamental techniques: laminoplasty and laminectomy with posterior fixation (LPF). There is still controversy concerning the technique in terms of outcome and complications. The aim of the present work is to analyze from the clinical and radiological point of view these 2 techniques: laminoplasty and LPF. Materials and methods A historical cohort of 39 patients was reviewed (12 LFP and 27 laminoplasty) including patients operated in a 10 years period at the Hospital Universitario La Paz with a follow-up of 12 months after surgery was carried out. The clinical results were analyzed and compared using the Nurick scale and the modified Japanese Orthopaedic Association Scale (mJOA) and the radiological results using the Cobb angle, Sagittal Vertical Axis, T1 Slope and alignment (measured by Cobb-T1 Sloppe). Results Significant differences were observed in the postoperative improvement of the Nurick scale (P=.008) and mJOA (P=.018) in the laminoplasty group. In LFP there is a tendency to a greater improvement, but statistical significance is not reached due to the low sample size of this group. No statistically significant differences were observed in the radiological variables. Regarding the total number of complications, a higher number was observed in the laminoplasty group (7 cases) versus LFP (one case), but no statistically significant differences were observed. (AU)

Influencia de la obesidad en los resultados del tratamiento quirúrgico de la estenosis lumbar degenerativa / Obesity Influence on the Surgical Treatment Results of Degenerative Lumbar Stenosis

Introducción: La estenosis lumbar degenerativa altera la calidad de vida y disminuye la capacidad funcional en adultos mayores. La obesidad representa un problema de la salud mundial actual. Objetivo: Detallar los efectos de la obesidad sobre el riesgo quirúrgico, los índices de complicaciones posoperatorias y los resultados funcionales en pacientes adultos mayores sometidos a cirugía electiva por estenosis lumbar degenerativa. Métodos: Estudio prospectivo-descriptivo, con pacientes adultos mayores intervenidos quirúrgicamente por diagnóstico de estenosis lumbar degenerativa y valorados un año después. Resultados: 55 pacientes, 23 obesos, 32 no obesos; relación de sexos 1,5:1 masculino-femenino, mayor cantidad de espacios intervenidos, tiempo quirúrgico y pérdida de sangre en obesos. Los obesos presentaron un mayor número de complicaciones postquirúrgicas y resultados funcionales menos buenos. Conclusiones: La obesidad constituye un mayor riesgo quirúrgico, que, aunque la diferencia en los resultados clínicos no sea muy importante, provoca intervenciones más prolongadas y mayor incidencia de complicaciones quirúrgicas(AU)

Introduction: Degenerative lumbar stenosis alters quality of life and decreases functional capacity in older adults. Obesity represents a current global health problem. Objective: To detail the effects of obesity on surgical risk, postoperative complication rates, and functional outcomes in older patients undergoing elective surgery for degenerative lumbar stenosis. Methods: Prospective-descriptive study with elderly patients who underwent surgery for a diagnosis of degenerative lumbar stenosis, who were evaluated one year later. Results: Fifty-five patients, 23 obese, 32 non-obese; sex ratio 1.5:1 male-female, higher number of intervened spaces, surgical time and blood loss in obese subjects. The obese patients showed higher number of post-surgical complications and less good functional results. Conclusions: Obesity constitutes a higher surgical risk, even when the difference in clinical results is not very important, it causes longer interventions and higher incidence of surgical complications(AU)

The clinical results were analyzed and compared using the Nurick scale and the modified Japanese Orthopaedic Association Scale (mJOA) and the radiological results using the Cobb angle, Sagittal Vertical Axis, T1 Slope and alignment (measured by Cobb-T1 Sloppe). RESULTS: Significant differences were observed in the postoperative improvement of the Nurick scale (p = 0.008) and mJOA (p = 0.018) in the laminoplasty group. In LFP there is a tendency to a greater improvement, but statistical significance is not reached due to the low sample size of this group. No statistically significant differences were observed in the radiological variables. Regarding the total number of complications, a higher number was observed in the laminoplasty group (7 cases) versus LFP (one case), but no statistically significant differences were observed. CONCLUSIONS: Laminoplasty and LFP are both safe and effective procedures in the treatment of cervical degenerative myelopathy. The findings of our study demonstrate statistically significant clinical improvement based on the Nurick and mJOA scales with laminoplasty. No significant differences in terms of complications or radiological variables were observed between the 2 techniques.

Percutaneous cement discoplasty in the treatment of degenerative disc disease. case series / Cimento discoplastia percutânea no tratamento da doença degenerativa do disco. série de casos / Cemento discoplastia percutánea en el tratamiento de la enfermedad discal degenerativa. serie de casos

ABSTRACT Introduction: Percutaneous cement discoplasty (PCD) is a minimally invasive surgical technique, which provides segmental stabilization and an indirect decompression effect in cases of severe degenerative disc disease with vacuum phenomenon, useful in patients with comorbidities that contraindicate invasive surgical procedures. Materials and methods: A retrospective analysis of 6 patients undergoing PCD was carried out, reporting the demographic variables, the segments treated and the clinical result evaluated by means of the visual analog pain scale (VAS) both in the presurgical and in the 6-month follow-up. Finally, a literature review was carried out. Results: 6 cases of PCD were included, of which 5 had a diagnosis of dyscarthrosis and 1 dyscarthrosis with spondylolisthesis. 4 female and 2 male patients. In 3 patients, PCD was performed in 1 segment and in 3 patients in multiple segments. Regarding the clinical result, an improvement was presented in 5 of the patients (mean 5.6 VAS points), 1 of the patients did not present improvement and required another surgical intervention. Conclusions: PCD is a minimally invasive technique useful in the treatment of spine pain secondary to degenerative disc disease in those patients with comorbidities that contraindicate a major procedure. Indirect foraminal decompression by PCD in one or more segments appears to contribute to pain relief. Level of Evidence III. Series of cases and controls.

RESUMO Introdução: O cimento discoplastia percutânea (PCD) é uma técnica cirúrgica minimamente invasiva, que proporciona estabilização segmentar e efeito descompressivo indireto nos casos de doença discal degenerativa grave com fenômeno de vácuo, útil em pacientes com comorbidades que contra-indicam procedimentos cirúrgicos agressivos. Materiais e métodos: Foi realizada uma análise retrospectiva de seis pacientes submetidos à PCD, relatando as variáveis demográficas, os segmentos tratados e o resultado clínico avaliado por meio da escala visual analógica de dor (EVA) tanto no pré-cirúrgico quanto no de seis meses acompanhamento. Por fim, foi realizada uma revisão da literatura. Resultados: foram incluídos seis casos de PCD, dos quais cinco apresentavam diagnóstico de disartrose e um de disartrose com espondilolistese. Quatro pacientes do sexo feminino e dois do sexo masculino. Em três pacientes, o PCD foi realizado em um segmento e em três pacientes em vários segmentos. Em relação ao resultado clínico, houve melhora em cinco dos pacientes (média 5.6 pontos EVA), um dos pacientes não apresentou melhora e necessitou de nova intervenção cirúrgica. Conclusões: A PCD é uma técnica minimamente invasiva útil no tratamento da dor da coluna secundário à doença degenerativa do disco em pacientes com comorbidades que contra-indicam um procedimento de grande porte. A descompressão foraminal indireta por PCD em um ou mais segmentos parece contribuir para o alívio da dor. Nível de Evidência III; Série de casos e controles.

Epidemiologia e prevalência da maculopatia miópica em centro de referência em oftalmologia / Epidemiology and prevalence of myopic maculopathy in an ophthalmology reference center

RESUMO Objetivo: Determinar a epidemiologia e a prevalência da maculopatia miópica e da miopia patológica e os fatores de risco associados. Métodos: Trata-se de estudo observacional transversal retrospectivo realizado em um serviço de oftalmologia, com 59 pacientes com idade entre 7 e 70 anos e equivalente esférico maior que -6 dioptrias. Suas retinografias foram laudadas segundo a classificação META-PM, por dois oftalmologistas e um retinólogo experiente. A análise estatística foi realizada conforme o Matlab R2010, com o Excel 2010 e o Statistical Package for the Social Sciences , versão 20.0, sendo utilizado o resultado da análise de regressão logística binária múltipla. Resultados: De acordo com a META-PM, a prevalência da maculopatia miópica nos cem olhos analisados foi de 19% para C0, 53% para C1,18% para C2,2% para C3 e 8% para C4. A prevalência da miopia patológica foi de 39%, sendo que 37% desses olhos possuíam maculopatia miópica C1 com lesões plus , C2 ou pior ou estafiloma posterior, e 2% apresentavam categoria menor que C2, sem lesões plus , porém com estafiloma posterior. A análise de regressão logística binária múltipla revelou associação entre idade e equivalente esférico com a presença da miopia patológica (p<0,05), evidenciando que o aumento de 1 ano na idade implicou em 1,05 vez (razão de chance de 1,05) mais chance de apresentar miopia patológica (p<0,001; intervalo de confiança de 95% de 1,02-1,08). O aumento de 1 dioptria no equivalente esférico maior que -6 dioptrias acarretou 1,19 vez (razão de chance de 1,19) maior risco de apresentar miopia patológica (p=0,001; intervalo de confiança de 95% de1,08-1,32). Por fim, não houve associação entre sexo e presença da miopia patológica (p=0,784). Conclusão: A classificação META-PM é uma ferramenta importante na padronização do estadiamento da lesão miópica, permitindo comparação entre estudos e normatização de condutas. O avançar da idade e o equivalente esféricomiópico estão relacionados à severidade da maculopatia miópica e à presença da miopia patológica.

ABSTRACT Objective: To determine the epidemiology and prevalence of myopic maculopathy and pathologic myopia and associated risk factors. Methods: This is a retrospective cross-sectional observational study performed at an ophthalmology center, including 59 patients aged 7 to 70 years, and spherical equivalent higher than -6 diopters. Their retinographies were assessed by two ophthalmologists and an experienced retina specialist, using the META-PM study classification. Statistical analysis was performed using Matlab R2010, Excel 2010 and Statistical Package for the Social Sciences version 20.0, based on the result of multiple binary logistic regression analysis. Results: According to META-PM, the prevalence of myopic maculopathy in 100 eyes analyzed was 19% C0; 53% C1; 18% C2; 2% C3; 8% C4. The prevalence of pathologic myopia was 39%, and 37% of these eyes having myopic maculopathy category C1 with lesions plus, C2 or worse, or posterior staphyloma, and 2% in category smaller than C2, without lesions plus, but with posterior staphyloma. Multiple binary logistic regression analysis revealed an association between age and spherical equivalent inpathologic myopia (p<0.05), demonstrating the increase by 1 year in age implied in 1.05-fold (odds ratio=1.05) more likelyto present pathologic myopia (p<0.001; 95%CI 1.02-1.08). The increase by 1 diopter in the spherical equivalent higherthan -6 diopters, led to 1.19-fold (odds ratio=1.19) greater risk of presenting pathologic myopia (p=0.001; 95%CI 1.08-1.32). Finally, there was no association between sex and pathologic myopia (p=0.784). Conclusion: The META-PM study classification is an important tool to standardize myopic lesion staging, allowing comparison between studies and establishing management. Advanced age and myopic spherical equivalent are related to severity of myopic maculopathy and pathologic myopia.

Incidence of neurosurgical pathology of the spine in population of Mexico City.

BACKGROUND: Spine pathologies have been increased in the past years worldwide being important cause of disability which represents significant economic losses. OBJECTIVE: The objective of the study was to establish the incidence of spinal neurosurgical pathology in a national reference hospital in Mexico City (General Hospital of Mexico "Dr. Eduardo Liceaga"). MATERIALS AND METHODS: A descriptive, observational, retrospective, and cross-sectional study was carried out, using the database of all patients that were undergoing spinal surgery from January 2015 to January 2020. Measures of central tendency and percentages, demographic variables, diagnosis, and affected segment were assessed. RESULTS: A total of 341 cases were analyzed, the group of patients with degenerative disease represents the main cause of care followed by neoplasms; trauma and special cases of congenital type and reoperations were the less frequent pathologies between the groups. In general, the most affected age group was 51-60 years. CONCLUSIONS: Within the study population, a wide range of diseases that affect the spine were treated, ranging from degenerative diseases, neoplasms, trauma, congenital, and infectious diseases.

El grupo de edad más afectado fue de entre 51 a 60 años. CONCLUSIONES: Dentro de la población de estudio se trataron una amplia gama de enfermedades que afectan a la columna, que van desde enfermedades degenerativas, neoplasias, traumatismos, enfermedades congénitas e infecciosas.

Analysis of visual disability in Buenos Aires, Argentina. Pathologic myopia is the leading cause in working age / Análisis de discapacidad visual en Buenos Aires, Argentina. La miopía patológica es la principal causa en edad laboral

Abstract This study assessed the causes of visual impairment over a decade in Buenos Aires City. This is a retrospective case series where we reviewed the database of visual disability certificates issued by the Buenos Aires City Ministry of Health between 2009 and 2017. In Argentina, visual disability is defined as a visual acuity ≤ 20/200 in the better eye, or a corresponding visual field of less than 20 degrees in the less impaired eye. The database included the following variables: year of issue, age, gender, and cause of visual disability. Between 2009 and 2017 a total of 7656 subjects were certified as legally blind. The mean age of the sample was 57 ± 21 years and 52.1% were females. The emission was near 700 certificates per year. The age distribution showed that 62.8% of certificates were from patients older than 50 years and that only 6.6% were given to subjects under 20. The leading causes of visual disability in Buenos Aires City were age-related macular degeneration (ARMD) with a rate of 15.5%, degenerative myopia (14.4%), primary open-angle glaucoma (11.3%) and diabetic retinopathy (6.6%). In subjects younger than 50, degenerative myopia was the first cause of visual disability. Interestingly in Argentina, where the prevalence of myopia is low, degenerative myopia is found to be the major cause of visual disability in middle-aged adult subjects. Population and clinical methods to avoid this preventable disease should need to be implemented as a matter of urgency.

Resumen Este trabajo estudia las causas de la discapacidad visual durante una década en la Ciudad de Buenos Aires. Se presenta una serie de casos retrospectiva donde se revisó la base de datos de certificados de discapacidad visual emitidos por el Ministerio de Salud de la Ciudad de Buenos Aires entre 2009 y 2017. En Argentina, la discapacidad visual se define como una agudeza visual ≤ 20/200 en el mejor ojo, o un campo visual correspondiente de menos de 20 grados en el ojo menos deteriorado. La base de datos incluyó las siguientes variables: año de emisión, edad, sexo y causa de la discapacidad visual. Entre 2009 y 2017 se certificaron un total de 7656 sujetos con ceguera legal. La edad media de la muestra fue de 57 ± 21 años y el 52.1% fueron mujeres. La distribución por edades mostró que el 62.8% de los certificados fueron dados a pacientes mayores de 50 años y que solo el 6.6% se otorgó a menores de 20 años. Las principales causas de discapacidad visual fueron la degeneración macular asociada a la edad (DMAE) (15.5%), la miopía degenerativa (14.4%), el glaucoma primario de ángulo abierto (11.3%) y la retinopatía diabética (6.6%). En los menores de 50 años, la miopía degenerativa fue la primera causa de discapacidad visual. Resulta interesante que, en Argentina, donde la prevalencia de miopía es baja, la miopía degenerativa sea la principal causa de discapacidad visual en adultos de mediana edad.

Cambios Clínicos e Imagenológicos en Terapias no Invasivas en Articulaciones Temporomandibulares con Alteraciones Óseas Degenerativas

RESUMEN: El objetivo del presente estudio fue describir los cambios clínicos e imagenológicos de las terapias no invasivas aplicadas a pacientes con alteraciones óseas degenerativas de las articulaciones temporomandibulares (ATM). Metodología: Se evaluaron 25 pacientes con alteraciones óseas degenerativas de las ATM, sin tratamiento previo de trastornos temporomandibulares (TTM) al momento del diagnóstico. Se realizó tratamiento no invasivo y un año después fueron evaluados según criterios clínicos e imagenológicos DC/TMD y Ahmad. Los resultados fueron presentados por medio de estadística descriptiva, odds ratio con sus respectivos intervalos de confianza, comparaciones de medianas y correlaciones. Se estudiaron 50 ATM, 72 % mujeres (32,2 años promedio). Se observó mejora significativa en los parámetros: dolor (p=0,0001), sinovitis (p=0,001) e incremento de la esclerosis del trabeculado óseo (p=0,051) a un año post-tratamiento. Después de un año del establecimiento de terapias no invasivas en pacientes con alteraciones óseas degenerativas de las ATM, se observaron cambios positivos tanto clínicos como imagenológicos, reduciéndose significativamente la sintomatología dolorosa, limitándose la progresión del daño óseo degenerativo, y observándose recuperación de los casos de sinovitis.

ABSTRACT: The objective of this study was to describe clinical and imaging changes of non-invasive therapies applied to patients with degenerative bone disorders of the temporomandibular joints (TMJ). To carry out this study, 25 patients with degenerative bone disorders of TMJ without previous treatment at the time of diagnosis, were evaluated. Non-invasive treatment was performed and one year later they were evaluated according to clinical and imaging criteria DC/TMD and Ahmad. Results were presented by descriptive statistics, odds ratio, confidence interval, comparisons of means, and correlations. 50 TMJs, 72 % women, (32.2 years mean of age) were studied. Significant improvement was observed in the parameters: pain (p=0.0001), synovitis (p=0.001), and increased sclerosis of the bone trabeculae (p=0,051) at one-year post-treatment. After one year of the establishment of non-invasive therapies in patients with degenerative joint disease of TMJ, it was observed positive changes, both clinical and imaging, reducing painful symptomatology, limiting effect on the progression of degenerative bone damage, and recovery of synovitis cases.

Plasma rico en plaqueta en el tratamiento de la enfermedad degenerativa discal / Platelet-rich plasma in the treatment of degenerative disc disease

Introducción: La enfermedad degenerativa discal es una entidad frecuente y uno de los principales motivos de consulta. Genera altas tasas de discapacidad, años útiles perdidos, así como altos costos económicos por asistencia médica y grandes pérdidas monetarias. Su tratamiento es generalmente conservador, aunque en la actualidad se incluyen terapias biológicas novedosas. Objetivo: Describir las principales propiedades biológicas que hacen del plasma rico en plaquetas una terapéutica efectiva para la enfermedad degenerativa discal. Métodos: Se realizó una revisión no sistemática de la bibliografía basada en artículos que se publicaron en bases de datos indexadas en Infomed como Hinari, Ebsco, Scielo, Pubmed, Cubmed, Cocrhane, Scopus, LILACS; en idioma español, inglés y portugués, durante los últimos diez años. Desarrollo: Se expusieron características clínico epidemiológicas de la enfermedad degenerativa discal, así como las propiedades biológicas que le permiten al plasma rico en plaqueta tener una función activa en la regeneración del disco intervertebral o el retraso de la cascada de degradación de este. Se resaltan los principales estudios de acuerdo a la vía de administración del plasma rico en plaquetas y sus resultados. Conclusiones: De acuerdo con lo publicado por los autores, el plasma rico en plaquetas es una alternativa efectiva en el tratamiento de la enfermedad degenerativa discal por la producción de factores derivados de las plaquetas, que intervienen en la degeneración del disco intervertebral, siendo la vía intradiscal la que más se emplea(AU)

Introduction: Degenerative disc disease is a frequent condition and one of the main reasons to attend the consultation. It generates high rates of disability, useful years lost, as well as high economic costs for medical assistance and large monetary losses. Its treatment is generally conservative, although novel biological therapies are currently included. Objective: To describe the main biological properties that make platelet-rich plasma an effective therapy against degenerative disc disease. Methods: A nonsystematic review of the bibliography was carried out based on articles published, during the last ten years, in databases indexed in Infomed, such as Hinari, Ebsco, Scielo, Pubmed, Cubmed, Cocrhane, Scopus, and LILACS, in Spanish, English and Portuguese. Development: Clinical-epidemiological characteristics of degenerative disc disease were presented, as well as the biological properties that allow platelet-rich plasma to have an active function in the regeneration of the intervertebral disc or the delay of its degradation cascade. The main studies are highlighted, according to the route of administration of platelet-rich plasma and their results. Conclusions: According to what has been published by authors, platelet-rich plasma is an effective alternative in the treatment of degenerative disc disease, due to the production of factors derived from platelets, which intervene in the degeneration of the intervertebral disc, being the intradiscal pathway the most used(AU)

Current status of the treatment of degenerative mitral valve regurgitation.

Degenerative mitral valve disease (myxomatous degeneration or fibroelastic deficiency) is the most common indication for surgical referral to treat mitral regurgitation. Mitral valve repair is the procedure of choice whenever feasible and when the results are expected to be durable. Posterior leaflet prolapse is the commonest lesion, found in up to two-thirds of patients. It is the easiest to repair, particularly when limited to one segment. In these cases, rates of repairability and procedural success approach 100%, and there is now ample evidence that the immediate and long-term results are better than those of valve replacement. Notably, minimally invasive valvular procedures, surgical or interventional, have attracted increasing interest in the last decade. When performed by experienced groups, mitral valve repair is unrivaled irrespective of the severity of lesions, from simple to complex, which leaflets are involved, and the type of degenerative involvement (myxomatous or fibroelastic). Its results should be viewed as the benchmark for other present and future technologies. By contrast, percutaneous mitral valve repair is still in its infancy and its results so far fall short of those of surgical repair. Nevertheless, continued investment in transcatheter procedures is of great importance to enable development and improved accessibility, particularly for patients who are considered unsuitable for surgery. In this review, we analyze the current status of management of degenerative mitral valve disease, discussing mitral valve anatomy and pathology, indications for intervention, and current surgical and transcatheter mitral valve procedures and results.

Lumbar degenerative spondylolisthesis II: treatment and controversies / Espondilolistesis degenerativa lumbar II: tratamiento y controversias

Abstract: There are various approaches and surgical techniques with the objective of nerve root decompression, restrict mobility, and fusion of the listhesis. Among the techniques, posterior interbody fusion combines direct and indirect root decompression with the fusion between vertebral bodies, placing an autologous bone graft between transverse apophysis and vertebral bodies. Transforaminal lumbar and posterior interbody fusion, on the same way, look to decompress and fuse but with a different approach to the spine. The anterior approach for interbody fusion provides a better fusion rate. Lateral lumbar interbody fusion is considered less invasive, with an anterolateral transpsoas approach. The lumbar fusion technique in degenerative spondylolisthesis must be individualized. Non-fusion decompression is considered a less invasive procedure. Various studies suggest that decompression has better results when fusion is added. Surgery had several potential benefits and greater improvement in those patients who fail conservative management. An optimal technique is not conclusively identified.

Resumen: El tratamiento de la espondilolistesis degenerativa lumbar es específico para cada etapa de la enfermedad y el manejo quirúrgico no debe de ser la primera elección en la mayoría de los casos. El manejo conservador está basado en el uso de antiinflamatorios no esteroideos, control de peso y rehabilitación. En caso de falla después de cuatro a seis semanas, el siguiente paso es la infiltración facetaria. En caso de dolor persistente, alteraciones neurológicas o claudicación neurogénica el siguiente paso es la cirugía. Existen varios abordajes y técnicas quirúrgicas con el objetivo de descomprimir las raíces nerviosas, restringir la movilidad y fusionar la listesis. Entre las técnicas quirúrgicas, la fusión posterior combina la descompresión directa e indirecta con artrodesis entre los cuerpos vertebrales, colocando injerto entre las apófisis transversas y los cuerpos vertebrales. La artrodesis intersomática transforaminal y posterior buscan de la misma manera la descompresión y fusión, pero con un abordaje distinto. El abordaje anterior para artrodesis intersomática provee la mejor tasa de fusión. La artrodesis intersomática lateral se considera un procedimiento menos invasivo, con un abordaje anterolateral transpsoas. La técnica de artrodesis lumbar en la espondilolistesis debe ser individualizada. La descompresión sin artrodesis se considera un procedimiento menos invasivo; varios estudios sugieren que la descompresión tiene mejores resultados cuando se agrega una artrodesis. La cirugía tiene múltiples beneficios posibles en pacientes en quienes el tratamiento conservador ha fallado. No se ha identificado una técnica óptima de tratamiento.

Evaluación funcional y del dolor en pacientes con deformidad espinal manejados quirúrgicamente.

BACKGROUND: The degenerative spine has an incidence greater than 60% in people over 60 years old. Functionality and pain is assessed by the Oswestry Disability Index (ODI) and the visual analogue pain scale (VAPS), respectively. OBJECTIVE: To evaluate the functionality and pain one year after surgery, in patients with degenerative spine. METHOD: Comparative, longitudinal study, in patients with degenerative spine surgically managed during 2016 to 2018. Functional aspects and pain were evaluated before surgery and one year later using ODI and VAPS. Descriptive statistics, measures of central tendency and dispersion, Student's t were used for the difference between the pre and postoperative values of both scales. RESULTS: There were 18 patients. Of these, 15 completed the follow-up; 8 were men and 7 women. The average age was 63.5 ± 4.8 years; 13 presented moderate post-surgical functional limitation, 2 intense functional limitation. There were statistically significant differences between the pre and postoperative values for ODI and VAPS (p = 0.011 and p = 0.017, respectively). CONCLUSIONS: Functionality and pain evaluated one year after surgery, have a statistically significant difference compared to evaluations before surgery in patients with spine deformity surgically treated.

RESULTADOS: De 18 pacientes, 15 completaron seguimiento (8 hombres y 7 mujeres). La edad promedio fue de 63.5 ± 4.8 años. Trece presentaron limitación funcional posquirúrgica moderada y dos limitación funcional intensa. Hubo diferencias estadísticamente significativas entre el preoperatorio y el posoperatorio para el ODI y la EVA (p = 0.011 y p = 0.017, respectivamente). CONCLUSIONES: La funcionalidad y el dolor evaluados 1 año después de la cirugía tienen diferencia estadísticamente significativa en comparación con las evaluaciones antes de la cirugía.

Functional outcomes and 8-year survival after hip arthroscopy in patients with degenerative hip disease. / Resultados funcionales y supervivencia a ocho años de la artroscopia de cadera en pacientes con patología degenerativa de cadera.

BACKGROUND AND PURPOSE: The purpose of this study is to identify which variables may have a significant impact in mid-term survivorship following hip arthroscopy. METHODS: This a single-centre single-surgeon retrospective study including 102 patients who underwent a hip arthroscopy procedure between August 2007 and October 2011. Each subject completed three questionnaires at final follow- up: Hip Outcome Score-Activities of Daily Living (HOS-ADL), Hip Outcome Score-Sport (HOS-S) and Modified Harris Hip Score (m-HHS). RESULTS: Thirty-nine patients (40 hips) were finally included in our study. Mean age was 43.1 ± 9.9 years with a three-year minimum follow-up (75.43 ± 25.2 months). Younger patients and those with a shorter duration of symptoms obtained significantly higher HOS-S and m-HSS scores. Patients who had undergone previous lumbar spinal surgery obtained significantly worse HOS-ADL scores. Patient acceptable symptom state (PASS) was achieved in 23 patients (57.5%) for m-HHS, 22 patients (55%) for HOS-ADL and 25 patients for HOS-S scores. No major complication was observed. Only four patients had minor complications. Mean survival time was 97.1 months (95% CI, 85.1 to 109.1 months), with a survival at 8 years of 69% (95% CI, 53% to 85%). CONCLUSIONS: Our findings suggest that hip arthroscopy is a safe procedure with acceptable functional outcomes after a long follow-up. Care should be taken when treating patients with prior lumbar surgery. LEVEL OF EVIDENCE: Level IV.
