ABSTRACT

Pivoting Brow Lift es una nueva opción terapéutica cuyas ventajas son tres mínimas incisiones, prácticamente imperceptibles, bien aceptadas por pacientes de todas las edades, sexo y incluso pacientes calvos. Una incisión se realiza en la región temporal y otra dentro del cuero cabelludo en la región medio frontal o en una arruga en pacientes calvos. La disección en región frontal es sub-perióstica, muchas veces llega a la punta nasal para reposicionarla. La disección en la región temporal se realiza entre las hojas superficiales y profundas extendiéndose hasta el tarso y canto externo del ojo; en la región palpebral la disección se realiza entre la piel y el musculo. La fijación son dos puntos externos en el cuero cabelludo y unos papeles adherentes. Los puntos del cuero cabelludo se retiran a los 14 días. Evita las complejas fijaciones que se realizan actualmente con tornillos, puntos internos o Endotime. La sencillez del procedimiento hace que este se pueda realizar entre 30 y 45 minutos, con anestesia local y sedación; esto permite lograr una mayor seguridad operatoria. Se han documentado pacientes tratados hace 9 años donde se demuestra la duración en el tiempo. El bajo índice de complicaciones y la alta satisfacción de los pacientes documentadas en encuestas hace que este procedimiento pueda ser considerado como una nueva opción terapéutica.

ABSTRACT

La resorción ósea alveolar suele dar lugar a que las inserciones de la mucosa interfieran para la construcción, estabilidad y retención de una prótesis removible, una opción que permite modificar este tejido se obtiene por medio de una vestibuloplastia. Actualmente se puede favorecer la cicatrización de heridas utilizando láser de alta potencia aplicado a procedimientos quirúrgicos orales. Se realiza reporte de caso en paciente femenino a la que se realizó procedimiento de vestibuloplastia con láser de Er,Cr:YSGG, utilizando de forma postoperatoria gel de quitosano en nanotransportador biomolécula EPX. Se observa una cicatrización rápida y favorable al combinar ambas terapéuticas, además al utilizar productos con quitosano se disminuye el riesgo de la necrosis de fibroblastos gingivales humanos como recientemente se reportó en el uso de colutorios de clorhexidina (AU)


Alveolar bone resorption often results in mucosal insertions interfering with the construction, stability and retention of a removable prosthesis, an option to modify this tissue is obtained by means of vestibuloplasty. Currently, wound healing can be promoted by using high power laser applied to oral surgical procedures. A case report of a female patient who underwent a vestibuloplasty procedure with laser Er,Cr:YSGG, using chitosan gel with EPX biomolecule nanocarriers postoperatively. A fast and favorable healing is observed when combining both therapeutics, besides, when using products with chitosan, the risk of necrosis of human gingival fibroblasts is reduced, as recently reported in the use of chlorhexidine mouthwashes (AU)

ABSTRACT

ABSTRACT Objective: To compare and evaluate the clinical efficacy of diode laser and cryosurgery for treating melanin pigmentation of gingiva. Material and Methods: A total of twenty-five subjects with physiological gingival pigmentation on the facial aspect of both maxillary and mandibular anterior arches (50 sites), both male and female, with an average age ranging from 18-35 years, participated in the study. The sites were randomly divided into Group I: depigmentation by Laser and Group II: depigmentation by Cryosurgery. The following parameters were assessed for the evaluation of treatment results: Melanin Oral Pigmentation Index (PI), Visual Analogue Scale (VAS) for pain evaluation and Healing index (HI). The data collected was statistically evaluated. Results: On intergroup comparison, there was no statistical difference in the score from baseline (p>0.05); however, a statistically significant difference was seen at the end of 1 year (p<0.05). Moreover, 57-60% of arches showed recurrence of pigmentation in the laser group whereas; only 12.7-17% recurrence was seen in the cryosurgery group at the end of the first year. Conclusion: Treatment of gingival hyperpigmentation with laser and cryosurgery shows a marked improvement of gingival pigmentation in both groups, but the cryosurgery depigmentation sites showed more sustainability.

ABSTRACT

Introducción: De acuerdo con el avance científico y tecnológico de la sociedad, se van implementando nuevas y mejoradas técnicas en la práctica dental, que están destinadas a ofrecer tratamientos efectivos, más rápidos, conservadores y que reduzcan los niveles de miedo y ansiedad en los pacientes. Objetivo: Interpretar los beneficios de emplear laserterapia en el campo odontológico, mediante una revisión bibliográfica. Métodos: Estudio del nivel exploratorio, auxiliado por la hermenéutica para interpretar la revisión bibliográfica ejecutada. Correspondió al tipo observacional, transversal, descriptivo y retrospectivo. Las búsquedas se efectuaron en las bases de datos: Lilacs, Pubmed, Sciencedirect y se buscaron estudios clínicos aleatorizados. Resultados: Se encontraron 252 artículos, de los cuales fueron seleccionados 7 de acuerdo con los criterios de inclusión y exclusión. Se percibieron resultados favorables sobre el láser en las especialidades de cirugía, endodoncia, periodoncia y patología oral, en comparación con las terapias consideradas como gold standard, lo que demuestra que el uso del láser es mejor o igual de efectivo que los tratamientos convencionales, ya que reduce el nivel de tiempo en las intervenciones, en tratamientos quirúrgicos evita el sangrado y el uso de sutura en algunos casos, además de que bien aceptado para pacientes porque también evita la presencia de dolor al aplicarlo. Conclusiones: Usando láser para intervenciones odontológicas se puede obtener una mejoría o al menos el mismo resultado que aplicando técnicas convencionales, lo que comprueba que es viable su uso(AU)


Introduction: In accordance with the scientific and technological progress of society, new and improved techniques are being implemented in dental practice that are aimed at offering effective, faster, and more conservative treatments that reduce the levels of fear and anxiety in patients. Objective: To interpret the benefits of using laser therapy in the dental field by means of a review of the literature. Methods: This was an exploratory study, aided by hermeneutics to interpret the literature review. It was observational, cross-sectional, descriptive, and retrospective. The searches were carried out in the following databases: Lilacs, Pubmed, Sciencedirect and randomized clinical studies were searched. Results: 252 articles were found, of which 7 were selected according to the inclusion and exclusion criteria. Favorable results were found on laser in the specialties of surgery, endodontics, periodontics, and oral pathology, in comparison with therapies considered as gold standard. thus, demonstrating that the use of laser is better or equally effective than conventional treatments, since it reduces the level of time in interventions, in surgical treatments it avoids bleeding and the use of suture in some cases, besides being well accepted for patients because it also avoids the presence of pain when applying it. Conclusions: Using laser for dental interventions an improvement can be obtained or at least the same result as applying conventional techniques, which proves that its use is feasible (AU)

ABSTRACT

Objetivo: La leucoplasia oral es el desorden maligno de la mucosa bucal más prevalente a nivel global y su manejo clínico sigue siendo un desafío. Se llevó a cabo una revisión sistemática para determinar la eficacia clínica de la terapia fotodinámica mediada por ácido 5-aminolevulínico tópico como una alternativa de quimio-prevención para las diferen- tes formas clínicas de la leucoplasia oral. Materiales y métodos: Empleando términos MeSH, se realizó una búsqueda exhaustiva en diferentes bases digi- tales de ensayos clínicos publicados en inglés en los últimos 30 años acerca del uso de la terapia fotodinámica mediada por ácido 5-aminolevulínico tópico como fotosensibilizador, y radiación láser de baja intensidad o luz LED como posibles fuentes de iluminación. Resultados: La revisión sistematizada que aplicó la guía PRISMA mostró una eficacia del 88,6% para este modo de fototerapia en el manejo de leucoplasias orales, con un 60,7% de respuesta completa y 27,9% de respuesta parcial. Además, el tamaño de efecto fue mayor para las formas clíni- cas homogéneas con cambios displásicos, independientemen- te del tipo de fuente de luz. La ausencia de respuesta fue del 11,4%, pero la evidencia empleada en este análisis fue mo- derada. Conclusión: La terapia fotodinámica mediada por áci- do 5-aminolevulínico tópico parece ser una alternativa útil en el manejo onco-preventivo de lesiones de leucoplasia oral. Sin embargo, es recomendable ejecutar ensayos clínicos controla- dos y aleatorizados con metodologías homogéneas que per- mitan generar un meta-análisis con un alto nivel de evidencia


Aim: Oral leukoplakia is globally the most prevalent ma- lignant disorder of the oral mucosa and its clinical manage- ment remains a challenge. A systematic review was carried out to determine the clinical efficacy of photodynamic therapy mediated by topical 5-aminolevulinic acid as an alternative for chemoprevention in the different clinical forms of oral leu- koplakia. Materials and methods: Using MeSH terms, an ex- haustive search was carried out in different digital databases of clinical trials published in English in the last 30 years on the use of photodynamic therapy mediated by topical 5-ami- nolevulinic acid as a photosensitizer, and low-intensity laser radiation or LED light as possible lighting sources. Results: The systematized review using PRISMA guide- lines showed an efficacy of 88.6% for this mode of photother- apy in the management of oral leukoplakias, based on 60.7% of complete response and 27.9% of partial response. In addi- tion, the effect size was larger in homogeneous clinical forms with dysplastic changes, regardless of the type of light source. There was an 11.4% of absence of response, but the evidence used in this analysis was moderate. Conclusion: Photodynamic therapy mediated by topical 5-aminolevulinic acid seems to be a useful alternative in the onco-preventive management of oral leukoplakia lesions. However, it is recommendable to perform controlled and ran- domized clinical trials with homogeneous methodologies that allow the generation of a meta-analysis with a high level of evidence (AU)

ABSTRACT

ABSTRACT Objective: To evaluate the efficacy of mitomycin C in anatomical and functional success after modified transcanalicular diode laser dacryocystorhinostomy. Methods: A prospective, double-blinded, randomized placebo-controlled study compared the effect of topical mitomycin C on modified transcanalicular diode laser dacryocystorhinostomy. Group 1 had modified transcanalicular diode laser dacryocystorhinostomy with topical saline, while Group 2 had modified transcanalicular diode laser dacryocystorhinostomy with topical mitomycin C. Success was defined as anatomical patency and relief of symptoms at the end of 6 months. Results: Six months after surgery, Group 1 (30 patients) showed anatomical and functional success rates of 86.7% and 83.3%, respectively. Group 2 (32 patients) showed anatomical and functional success rates of 87.5% and 84.3%, respectively. There was no statistically significant difference between the groups 1 and 2 (p = 1.000). Conclusion: The use of mitomycin C did not improve the anatomical and functional success rates of modified transcanalicular diode laser dacryocystorhinostomy compared to placebo.

ABSTRACT

RESUMO Objetivo: Identificar se há mudança refracional significativa após realização de capsulotomia posterior com laser Nd:YAG em olhos pseudofácicos. Métodos: Estudo retrospectivo com análise de prontuários de pacientes atendidos em um hospital com diagnóstico de opacificação de cápsula posterior do cristalino tratada com capsulotomia posterior com laser Nd:YAG no período de outubro de 2019 a março de 2021. A comparação entre a refração antes e após o procedimento foi realizada calculando-se o equivalente esférico. Também foi avaliada a mudança da acuidade visual, aferida por LogMAR. Resultados: Foram analisados 90 prontuários, totalizando 140 olhos, de pacientes submetidos à capsulotomia posterior com laser Nd:YAG. O equivalente esférico médio pré-procedimento foi de -0,07±0,89D, mínimo de -3,0D e máximo de +2,5D, mediana (intervalo interquartil) de 0,0D (-0,50D a +0,375D). A média pós-procedimento foi de -0,18±0,86D, mínimo de -3,5D e máximo de +2,25D, mediana (intervalo interquartil) de -0,125D (-0,50D a 0,0D). com p<0,0082. Dos 140 olhos, 66 sofreram miopização e 37 hipermetropização. A média de alteração do equivalente esférico geral foi de -0,12±0,51D, mínimo de -2,50D e máximo de +1,25D, mediana (intervalo interquartil) de 0,0D (-0,375D a +0,125D). Ao se comparar a diferença entre o equivalente esférico antes e após o procedimento do grupo de olhos que sofreu miopização (n=66) ou hipermetropização (n=37), separadamente, ambos obtiveram p<0,0001. Ao se compararem todos os olhos que sofreram alguma alteração refracional (n=103), foi encontrado p=0,008. A acuidade visual média pré-procedimento foi de 0,23±0,32, mínimo de 0,0 e máximo de 2,3. Pós-procedimento, a média foi de 0,06±0,13, mínimo de -0,12 e máximo de 0,7, com p<0,0001. Conclusão: A capsulotomia posterior com laser Nd:YAG gerou melhora significativa da acuidade visual nos pacientes do estudo, porém também gerou alteração refracional significativa após o procedimento, tanto para miopização (a mais frequente), quanto para hipermetropização.


ABSTRACT Objective: To identify if there is a significant change on refraction after Nd:YAG laser posterior capsulotomy in pseudophakic eyes. Methods: A retrospective study with analysis of medical records of patients treated at a hospital, with diagnosis of opacification of posterior lens capsule treated with Nd:YAG laser posterior capsulotomy, from October 2019 to March 2021. The comparison of refraction before and after the procedure was performed by calculating the spherical equivalent. Changes in visual acuity (VA), measured by LogMAR, were also evaluated. Results: A total of 90 medical records (140 eyes) of patients submitted to Nd:YAG laser posterior capsulotomy were analysed. The mean pre-procedure spherical equivalent was -0.07±0.89D, minimum of -3.0D and maximum of +2.5D, median (interquartile range) of 0.0D (-0.50D to +0.375D). The post-procedure mean was -0.18±0.86D, minimum of -3.5D and maximum of +2.25D, median (interquartile range) of -0.125D (-0.50D to 0.0D), with p <0.0082. Of the 140 eyes, 66 underwent myopia and 37 hyperopia, the mean change in the general spherical equivalent was -0.12±0.51D, minimum -2.50D and maximum +1.25D, median (interquartile range) of 0.0D (-0.375D to +0.125D). When comparing the difference between the spherical equivalent before and after the procedure of the group of eyes that underwent myopia (n=66) or hyperopia (n=37), separately, both obtained p<0.0001. When comparing all eyes that suffered any change on refraction (n=103), the p value was 0.008. The mean pre-procedure visual acuity was 0.23±0.32, minimum of 0.0 and maximum of 2.3. After the procedure, the mean was 0.06±0.13, minimum of -0.12 and maximum of 0.7, p<0.0001. Conclusion: Nd:YAG laser posterior capsulotomy significantly improved visual acuity of patients in this study; however, it also led to a significant change on refraction after the procedure, both for myopization, which was more frequent, and for hyperopization.

ABSTRACT

Introducción: La capsulotomía láser representa el único tratamiento efectivo para tratar la opacidad de cápsula posterior -causa más común de disminución de la visión después de una cirugía de catarata-. Este proceder es sencillo, pero no exento de complicaciones. Hasta ahora su aprendizaje se realiza directamente en los pacientes. El uso de simuladores permite el aprendizaje de la técnica sin dañar al paciente y sin la obligada presencia del profesor. Objetivo: Validar la confección de un modelo de ojo artificial como simulador para el entrenamiento de residentes de oftalmología en capsulotomía posterior con láser. Métodos: Estudio observacional, descriptivo y prospectivo en el Instituto Cubano de Oftalmología "Ramón Pando Ferrer", realizado desde febrero hasta marzo de 2019. Se confeccionó un modelo que simula el ojo pseudofáquico con opacidad de cápsula posterior. Se eligieron ocho residentes de oftalmología de primer año que nunca habían realizado una capsulotomía láser. Todos observaron la ejecución de la capsulotomía en pacientes reales y en el modelo docente, mientras recibían la explicación de la técnica. Posteriormente, cada estudiante efectuó el proceder sobre el simulador en tres ocasiones, y se evaluó en cuanto al completamiento de la capsulotomía y los impactos al lente. Resultados: Se obtuvo un modelo de simulación para el entrenamiento de la capsulotomía posterior láser con el uso de materiales reusables. El promedio de disparos para completar el proceder fue superior al necesario en pacientes reales. No obstante, el número de disparos e impactos de láser en el lente intraocular se redujo con las sucesivas sesiones de entrenamiento. Conclusiones: El simulador confeccionado es económico y de fácil factura. Su uso resulta funcional para el entrenamiento sistemático de la capsulotomía posterior con Nd. YAG láser, sin riesgo de daño para el paciente. Contribuye a perfeccionar el enfoque y a minimizar los impactos en la lente intraocular, por lo que se muestra como un medio didáctico útil para la formación y evaluación de habilidades de los residentes de oftalmología(AU)


Introduction: Laser capsulotomy is the only effective treatment for posterior capsule opacity, the commonest cause of decreased vision after cataract surgery. This procedure is simple, but not without complications. Until now, learning such procedure has been carried out directly on patients. Using simulators allows learning the technique without harming patients and without the professor's obligatory presence. Objective: To validate the creation of an artificial eye model to be used as a simulator for the training of Ophthalmology residents in posterior capsulotomy with laser. Methods: Observational, descriptive and prospective study carried out, from February to March 2019, at Ramón Pando Ferrer Cuban Institute of Ophthalmology. A model was made that simulates the pseudophakic eye with posterior capsule opacity. Eight first-year Ophthalmology residents who had never performed a laser capsulotomy were selected. All the participants observed the performance of capsulotomy in real patients, as well as in the teaching model, while receiving the explanation regarding the technique. Subsequently, each student performed the procedure with the simulator on three occasions, and received an evaluation based on the completion of the capsulotomy and the impacts to the lens. Results: A simulation model was obtained for training posterior laser capsulotomy with the use of reusable materials. The average number of shots to complete the procedure was higher than necessary in real patients. However, the number of shots and laser impacts on the intraocular lens decreased with successive training sessions. Conclusions: The simulator created is cheap and easy to make. Its use is functional for the systematic training of posterior capsulotomy with neodymium. Yttrium aluminium garnet (YAG) laser did not have any risks to the patient. It contributes to perfecting the focus and minimizing the impacts on the intraocular lens; therefore, it is shown as a useful didactic means for the training and evaluation of skills of Ophthalmology residents(AU)

ABSTRACT

Objetivo: Describir la discapacidad visual del diabético de 50 años y más de edad y la cobertura de la atención oftalmológica en Cuba durante el año 2016. Métodos: Se realizó una investigación epidemiológica, descriptiva y transversal que tomó la encuesta rápida de ceguera evitable realizada en Cuba en el año 2016, la cual incluyó la retinopatía diabética validada por la Organización Mundial de la Salud. Con los datos obtenidos en los cuestionarios se confeccionó una base de datos donde se tomaron todos los diabéticos conocidos o no con discapacidad visual. Resultados: La prevalencia de cualquier tipo de discapacidad visual en el diabético es de 25,4 por ciento (21,8-28,9). El riesgo de desarrollar discapacidad visual moderada, grave y ceguera es de 19,4 por ciento (16,5-22,3), 2,8 por ciento (1,0-4,6) y 3,2 por ciento (1,5-4,8) respectivamente. La catarata es la primera causa de discapacidad. El riesgo de discapacidad visual en el diabético es similar para uno y otro sexo y se incrementa con la edad. Las coberturas de tratamiento son bajas. Conclusiones: En Cuba, alrededor de un cuarto de los diabéticos tienen algún riesgo de discapacidad visual. El diabético tiene mayor riesgo de discapacidad visual moderada; sin embargo, el riesgo de discapacidad visual grave y de ceguera es el mismo para toda la población de 50 años y más de edad. La catarata y la retinopatía diabética son las causas más frecuentes de discapacidad visual en el diabético. Se evidencian dificultades con la atención oftalmológica, que incluye el examen y la cobertura de tratamiento de la catarata y del láser para la retinopatía diabética(AU)


Objective: Describe visual impairment among diabetics aged 50 years and over, and the coverage of ophthalmological care in Cuba in the year 2016. Methods: A descriptive cross-sectional epidemiological study was conducted based on the Rapid Assessment of Avoidable Blindness survey developed in Cuba in the year 2016, which included diabetic retinopathy with validation by the World Health Organization. The data obtained from the questionnaires were transferred to a database of visually impaired known and unknown diabetics. Results: Prevalence of any sort of visual impairment among diabetics is 25.4 percent (21.8-28.9). Risk of developing moderate visual impairment, severe visual impairment or blindness is 19.4 percent (16.5-22.3), 2.8 percent (1.0-4.6) and 3.2 percent (1.5-4.8), respectively. Cataract is the leading cause of impairment. Risk of visual impairment among diabetics is similar in the two sexes and increases with age. Treatment coverage is low. Conclusions: In Cuba, about one fourth of the diabetics are at some risk of visual impairment. Diabetics are at a higher risk of moderate visual impairment. However, the risk of severe visual impairment and blindness is the same as for the population aged 50 years and over. Cataract and diabetic retinopathy are the most common causes of visual impairment among diabetics. Difficulties were found in ophthalmological care, including examination and treatment coverage for cataract and laser therapy for diabetic retinopathy(AU)

ABSTRACT

Resumo Contexto Existem diversas formas de tratamento de varizes de membros inferiores. Entre elas, destaca-se o uso do laser diodo de 1.470 nm. Essa técnica proporciona aos pacientes uma cirurgia em regime ambulatorial, com retorno precoce à atividade ocupacional, bom resultado estético e baixo índice de complicações. No entanto, ainda se discute exaustivamente variáveis como comprimento de onda do laser, potência aplicada em cada área, tipo de fibra, necessidade ou não de tumescência e densidade de energia endovenosa linear. Objetivos Analisar os resultados do tratamento da insuficiência venosa superficial com laser diodo de 1.470 nm. Métodos Estudo retrospectivo, realizado em uma clínica privada de um hospital privado em Florianópolis a partir de dados colhidos prospectivamente. As amostras eram de 287 pacientes submetidos à cirurgia para tratamento da insuficiência venosa superficial com laser diodo de 1.470 nm, de janeiro de 2016 a dezembro de 2018, totalizando 358 veias safenas magnas e 84 veias safenas parvas tratadas. Resultados A taxa de oclusão total após 12 meses de cirurgia foi de 94,4%, com densidade de energia endovenosa linear média de 45,90 J/cm nas veias safenas magnas e de 96,4% com densidade de energia endovenosa linear média de 44,07 J/cm nas veias safenas parvas. Conclusões No período acompanhado, o laser diodo de 1.470 nm mostrou-se um tratamento seguro, muito efetivo e com baixas taxas de complicações (dor, edema, equimose, trombose venosa profunda e trombose induzida pelo calor endovenoso).


Abstract Background There are several ways to treat varicose veins of the lower limbs, among which use of 1470nm diode lasers stands out. This technique can be used to treat patients in outpatient settings, with early return to work, good esthetic results, and low rates of complications. However, variables such as the laser wavelength, the power administered in each area, the type of fiber, and the linear intravenous energy density (LEED) are still extensively discussed. Objectives To analyze the results of superficial venous insufficiency treatment with a 1470nm diode laser. Methods Retrospective study conducted at a private clinic in a private hospital in Florianopolis, based on a database collected prospectively. The sample comprised 287 patients who underwent surgery to treat superficial venous insufficiency with 1470nm diode laser, from January 2016 to December 2018, totaling 358 great saphenous veins (GSVs) and 84 small saphenous veins (SSVs) treated. Results The total occlusion rates after 12 months of surgery were 94.4% in the GSVs, with an average LEED of 45.90 J/cm, and 96.4% in the SSVs, with an average LEED of 44.07 J/cm. Conclusions During the follow-up period, the 1470nm diode laser proved to be a safe treatment, with great efficacy and low rates of complications (pain, edema, bruising, deep vein thrombosis, and endothermal heat-induced thrombosis - EHIT).

ABSTRACT

ABSTRACT Objective To identify preoperative clinical characteristics of patients undergoing femtosecond laser-assisted anterior lamellar keratoplasty who failed to achieve optimal postoperative visual outcomes. Methods In this single-center, retrospective case series, patients who underwent femtosecond laser-assisted anterior lamellar keratoplasty between 2013 and 2018 were included if they required graft revision, subsequent corneal procedure, or additional postoperative visits for a femtosecond laser-assisted anterior lamellar keratoplasty-related issue. Visual outcomes assessed included best-corrected visual acuities and postoperative corneal astigmatism. Results Eight eyes of eight patients meeting the above criteria were included. Mean patient age was 64.5 years (range, 21 to 89 years). Mean included preoperative best-corrected visual acuities was one logarithm of the minimum angle of resolution (range, 0.3 logarithm of the minimum angle of resolution to counting fingers). Indications for femtosecond laser-assisted anterior lamellar keratoplasty included anterior stromal scarring due to viral keratitis (two cases), bacterial keratitis (one case), chronic epithelial defect (one case), Avellino dystrophy (one case), trauma (one case), and chronic endothelial failure (two cases). Six patients had history of prior intraocular surgeries including phacoemulsification (four cases), pars plana vitrectomy (one case), endothelial keratoplasty (two cases), and trabeculectomy (one case). Mean included best-corrected visual acuities at most recent follow-up was one logarithm of the minimum angle of resolution (range zero logarithm of the minimum angle of resolution to hand movements) representing improvement or stability in six of eight patients. Visually significant corneal astigmatism was present in four of eight patients. Post-femtosecond laser-assisted anterior lamellar keratoplasty procedures included graft repositioning, arcuate keratotomy, phacoemulsification, and regraft. Conclusion While femtosecond laser-assisted anterior lamellar keratoplasty offers a less-invasive treatment option compared to penetrating keratoplasty, intraoperative and postoperative management can be complex. Femtosecond laser-assisted anterior lamellar keratoplasty in patients with history of prior endothelial keratoplasty or ongoing ocular comorbidities should be pursued with caution.


RESUMO Objetivo Identificar as características clínicas pré-operatórias de pacientes submetidos à ceratoplastia lamelar anterior assistida por laser de femtossegundo que não alcançaram resultados visuais pós-operatórios ideais. Métodos Nesta série de casos retrospectiva em um único centro, os pacientes submetidos à ceratoplastia lamelar anterior assistida por laser de femtossegundo entre 2013 e 2018 foram incluídos se precisassem de revisão do enxerto, procedimento corneano subsequente ou visitas pós-operatórias adicionais por uma intercorrência relacionada à ceratoplastia lamelar anterior assistida por laser de femtossegundo. Os resultados visuais avaliados incluíram melhor acuidade visual corrigida e astigmatismo pós-operatório da córnea. Resultados Oito olhos de oito pacientes que atenderam aos critérios descritos foram incluídos. A idade média dos pacientes foi de 64,5 anos (variação de 21 a 89). A melhor acuidade visual corrigida pré-operatória média foi de um logaritmo do mínimo ângulo de resolução (variação de 0,3 logaritmo do mínimo ângulo de resolução para contagem de dedos). As indicações para ceratoplastia lamelar anterior assistida por laser de femtossegundo incluíram cicatriz do estroma anterior devido à ceratite viral (dois casos), ceratite bacteriana (um caso), defeito epitelial crônico (um caso), distrofia de Avellino (um caso), trauma (um caso) e insuficiência endotelial crônica (dois casos). Seis pacientes tinham história de cirurgias intraoculares anteriores, incluindo facoemulsificação (quatro casos), vitrectomia via pars plana (um caso), ceratoplastia endotelial (dois casos) e trabeculectomia (um caso). O mínimo ângulo de resolução médio no acompanhamento mais recente foi de um logaritmo do mínimo ângulo de resolução (variação de zero logaritmo do mínimo ângulo de resolução para movimentos das mãos), representando melhora ou estabilidade em seis de oito pacientes. Astigmatismo corneano visualmente significativo estava presente em quatro de oito pacientes. Os procedimentos pós-ceratoplastia lamelar anterior assistida por laser de femtossegundo incluíram reposicionamento do enxerto, ceratotomia arqueada, facoemulsificação e enxerto. Conclusão Embora a ceratoplastia lamelar anterior assistida por laser de femtossegundo ofereça uma opção de tratamento menos invasiva em comparação com a ceratoplastia penetrante, o manejo intra e pós-operatório pode ser complexo. A ceratoplastia lamelar anterior assistida por laser de femtossegundo em pacientes com história de ceratoplastia endotelial anterior ou comorbidades oculares correntes deve ser avaliada com cautela.

ABSTRACT

Resumo Contexto Na insuficiência venosa crônica (IVC), a veia safena parva (VSP) é afetada em 15% dos casos. A cirurgia convencional é a técnica padrão para o tratamento da insuficiência da VSP, sendo a lesão no nervo sural uma complicação bastante temida. O tratamento de termoablação com endolaser tende a ser um método cirúrgico que diminui complicações da terapia cirúrgica da IVC. Objetivos Avaliar os pacientes com IVC submetidos à terapia por endolaser da VSP ao menos 30 dias após o procedimento. Métodos Foram analisados 54 membros inferiores de 46 pacientes submetidos à terapia por endolaser 1470 nm, sob anestesia local, para o tratamento da IVC em um hospital terciário. Os pacientes foram avaliados no período pré-operatório, intraoperatório e pós-operatório de 30 dias, através da clínica, exame físico e achados ecográficos. Resultados Nos 54 membros inferiores submetidos ao tratamento, comparando-se o período pré-operatório e o 30º dia pós-operatório, houve diferença significativa (p < 0,003) na redução do diâmetro da VSP tratada (6,37 mm pré-operatório e 5,15 mm no 30º dia pós-operatório) (IC95% 4,58-5,72) e na melhora do escore de gravidade clínica venosa (VCSS) (média de 8,02 pré-operatório e 6,11 no 30º dia pós-operatório) (IC95% 5,01-7,21) (p < 0,02). Complicações pós-operatórias, como parestesia e flebite, estiveram presentes e foram diagnosticadas em cinco e três pacientes, respectivamente, sem significar alteração na qualidade de vida e nas atividades de rotina. Conclusões A técnica de termoablação com laser da VSP mostrou-se segura e eficaz na redução dos sintomas clínicos e na melhora da qualidade de vida.


Abstract Background The small saphenous vein (SSV) is affected in 15% of chronic venous insufficiency (CVI) cases. Conventional surgery is the standard technique for treatment of SSV insufficiency, but sural nerve injury is a complication of great concern. Endovenous laser ablation is a surgical technique for treatment of CVI that is considered likely to reduce morbidity and mortality. Objectives To evaluate patients with CVI undergoing endovenous laser ablation of the SSV at least 30 days after the procedure. Methods We analyzed 54 lower extremities in 46 patients scheduled for 1470-nm endovenous laser ablation under local anesthesia to treat CVI in a tertiary hospital. Patients were evaluated preoperatively, intraoperatively, and postoperatively over 30 days with clinical examination, physical examination, and ultrasound. Results In the 54 lower extremities treated, there was a significant difference (p < 0.003) in terms of reduction in the diameter of treated veins (6.37 mm preoperatively and 5.15 mm on the 30th postoperative day) and improvement in the venous clinical severity score (VCSS) (means of 8.02 preoperative and 6.11 on the 30th postoperative day) (95%CI, 5.01—7.21) (p < 0.02). Postoperative complications such as paresthesia and phlebitis were present and diagnosed in 5 and 3 patients, respectively, but did not affect their quality of life or routine activities. Conclusions Intravenous laser ablation of the SSV proved to be safe and effective for reducing clinical symptoms and improving quality of life.

ABSTRACT

RESUMEN Objetivo: Determinar las características clínicas y epidemiológicas de la maculopatía diabética en adultos de 50 años y más en Cuba. Métodos: Se realizó una investigación epidemiológica, descriptiva transversal, que tomó la Encuesta Rápida de Ceguera Evitable realizada en Cuba en el año 2016, la cual incluyó la retinopatía diabética validada por la Organización Mundial de la Salud. Resultados: La prevalencia de cualquier grado de maculopatía fue de 8,5 por ciento (6,1 a 10,8) y la maculopatía observable y remitible fue de 4,2 por ciento (2,2 a 6,0). El riesgo de desarrollar maculopatía resultó mayor en el sexo femenino, con el 9,3 por ciento (6,6-12,9), y en los diabéticos que tenían entre 60 y 69 años de edad, de 9,2 por ciento (5,7-14,0). Este riesgo se incrementaba si existía descontrol de la glicemia y si la enfermedad tenía 15 años y más de evolución. La asociación con la retinopatía observable fue de 2,5 por ciento. La discapacidad visual moderada por maculopatía fue de 1,4 % y la grave junto con la ceguera de 0,8 por ciento. La cobertura de tratamiento fue baja (28,6 por ciento por personas). Conclusiones: El diabético de 50 años y más en Cuba tiene baja prevalencia de maculopatía diabética, la cual se comporta de manera similar para la forma observable y para la remitible. La retinopatía no proliferativa moderada tiene mayor riesgo de afectación macular. La discapacidad visual por afectación macular en el diabético es baja, aunque la estrategia de atención oftalmológica en el diabético no alcanza los estándares necesarios de efectividad, relacionados con la cobertura del tratamiento con láser(AU)


ABSTRACT Objective: Determine the clinical and epidemiological characteristics of diabetic maculopathy in adults aged 50 years and over in Cuba. Methods: A descriptive cross-sectional epidemiological study was conducted based on the Rapid Assessment of Avoidable Blindness survey developed in Cuba in the year 2016, which included diabetic retinopathy with validation by the World Health Organization. Results: Prevalence of any maculopathy grade was 8.5 percent (6.1 to 10.8), whereas observable, referable maculopathy was 4.2 percent (2.2 to 6.0). Risk for maculopathy was higher in the female sex with 9.3 percent (6.6-12.9) and among diabetics from the 60-69 years age group with 9.2 percent (5.7-14.0). Risk increased in uncontrolled glycemia and when the evolution of the disease was 15 years and over. Association with observable retinopathy was 2.5 percent. Moderate visual disability due to maculopathy was 1.4 percent, while severe disability and blindness were 0.8 percent. Treatment coverage was low (28.6 percent per persons). Conclusion: Prevalence of maculopathy is low among diabetics aged 50 years and over in Cuba, with similar behavior in the observable and the referable variants. Moderate non-proliferative retinopathy shows a higher risk for macular damage. Visual disability due to macular damage is low among diabetics, though the ophthalmological care strategy for diabetics does not achieve the required effectiveness standards in terms of laser therapy coverage(AU)

ABSTRACT

Occipital neuralgia (ON) is an uncommon cause of headache, and it is characterized by a stabbing paroxysmal pain that radiates to the occipital region. The present study includes a review of the literature and a case report. The etiology of this pathology can vary from traumas, infections, compressions of nerves or vertebrae, skull base surgeries, to degenerative changes and congenital anomalies. However, most of the time, the etiology is considered idiopathic. The diagnosis is essentially clinical. However, it is crucial that other types of primary headache are excluded. The treatment for ON may be based on nerve blocks, medications or surgeries. Neurectomy of the second spinal nerve is among the surgical techniques available.

ABSTRACT

Abstract Purpose: To determine the impact of neodymium:YAG (Nd:YAG) laser posterior capsulotomy on quality of life and visual acuity in adults. Methods: A prospective study that included patients over 65 years old with clinical indications for Nd: YAG laser capsulotomy. On the day of the procedure, corrected distance visual acuity tests, slit-lamp examination and posterior capsule opacification (PCO) photo documentation were performed, followed by application of the National Eye Institute Visual Function Questionnaire (NEI-VFQ-25). The PCO rate was evaluated with Evaluation of Posterior Capsule opacification (EPCO 2000) software. Four weeks after the posterior capsulotomy, corrected distance visual acuity was measured, and the NEI-VFQ-25 was applied again. Complications were also reported. Results : Sixty eyes from 45 patients were enrolled in the study. The mean age was 71.51 ± 6.38 years (65 to 93). Comparing the results before and after the Nd:YAG laser capsulotomy, there was a statistically significant improvement in quality of life according to the NEI-VFQ-25 (p<0.001) and in visual acuity (p=0.0). The mean score in NEI-VFQ-25 Questionnaire before capsulotomy was 62.07 ± 20.90 (16.81-95.90) and after was 83.95±19.49 (20.68 - 100.0). The mean CDVA before the procedure was 0.75 ± 0.35 LogMAR (0.1-1.3) and after was 0.21 ± 0.20 LogMAR (0.0-1.3). The mean PCO rate measured by the EPCO software was 0.688 ± 0.449. There was a positive correlation between the EPCO score and the total score of quality of life after Nd: YAG laser capsulotomy (r=0.845, p=0.00). Damage to intraocular lens was the only complication observed in six eyes (10%). Conclusion: Nd: YAG laser capsulotomy, in addition to improving visual acuity, is able to improve quality of life.


Resumo Objetivo: Determinar o impacto da capsulotomia posterior com laser de neodímio: YAG (Nd: YAG) na qualidade de vida e na acuidade visual em adultos. Métodos: Estudo prospectivo que incluiu pacientes acima de 65 anos com indicação clínica para capsulotomia com laser de Nd: YAG. No dia do procedimento, foram realizados testes de acuidade visual corrigida, exame com lâmpada de fenda e fotodocumentação da opacificação da cápsula posterior (OCP), seguido da aplicação do National Eye Institute Visual Function Questionnaire (NEI-VFQ-25). A taxa de OCP foi avaliada utilizando o software de avaliação de opacificação de cápsula posterior (EPCO 2000). Quatro semanas após a capsulotomia posterior, a acuidade visual corrigida foi medida, e o NEI-VFQ-25 foi aplicado novamente. Complicações também foram relatadas. Resultados: Sessenta olhos de 45 pacientes foram incluídos no estudo. A idade média foi de 71,51±6,38 anos (65 to 93). Comparando os resultados antes e após a capsulotomia com laser Nd: YAG, houve melhora estatisticamente significante na qualidade de vida de acordo com o NEI-VFQ-25 (p <0,001) e na acuidade visual (p = 0,0). A média do escore total do questionário NEI-VFQ-25 pré capsulotomia foi de 62.07 ± 20.90 (16.81-95.90) e pós foi de 83.95 ±19.49 (20.68 - 100.0). A AVCC antes do procedimento foi 0.75 ± 0.35 LogMAR (0.1-1.3) e após foi 0.21 ± 0.20 LogMAR (0.0-1.3). A taxa média de OCP medida pelo software EPCO foi de 0,688 ± 0,449. Houve correlação positiva entre o escore EPCO e o escore total de qualidade de vida após a capsulotomia com laser de Nd: YAG (r = 0,845, p = 0,00). O dano à lente intraocular foi a única complicação observada em seis olhos (10%). Conclusão: A capsulotomia com laser Nd: YAG, além de melhorar a acuidade visual, é capaz de melhorar a qualidade de vida.

ABSTRACT

ABSTRACT: The pigmented lesions of the oral cavity may be endogenous or exogenous. Endogenous lesions are benign and usually caused by melanin, and they are called gingival melanin pigmentations. Among the options for depigmenting these areas, laser therapy stands out for being a minimally invasive procedure. This study aims to report a clinical case of the gingival depigmentation technique using a high-power diode laser in the anterior maxillary region, for the ablation of the pigmented tissue to improve gingival aesthetics. The patient had an aesthetic complaint of the darkened aspect of the gingiva in the anterior maxillary and mandibular portions. After local anesthesia, we started depigmentation with high-power diode laser and performed ablation from the attached gingiva toward the free marginal gingiva. The patient returned after 30 and 180 days presenting healthy gingiva and absence of melanin repigmentation. Thus, we concluded that the diode laser was a good alternative for melanin depigmentation because it is a procedure with lower morbidity and satisfactory postoperative results.


RESUMEN: Las lesiones pigmentadas de la cavidad oral pueden ser endógenas o exógenas. Las endógenas son benignas y generalmente causadas por la melanina, denominándose pigmentaciones melánicas gingivales. Entre las opciones para la despigmentación de estas regiones, se destaca la laserterapia, por ser un procedimiento poco invasivo. Este trabajo tuvo como objetivo relatar un caso clínico de la técnica de despigmentación gingival utilizando láser de diodo de alta intensidad en la región anterior de los maxilares para ablación del tejido pigmentado con la finalidad de mejorar la estética gingival. El paciente presentaba como queja estética el aspecto oscurecido de la encía en la región anterior de la maxila y de la mandíbula. Tras aplicar anestesia local, se inició la despigmentación con láser de diodo de alta intensidad, siendo que la ablación se realizó a partir de la encía insertada hacia la encía marginal libre. El paciente regresó tras 30 y 180 días, presentando encía saludable y con ausencia de repigmentación melánica. Así fue posible concluir que el láser de diodo mostró ser una buena alternativa para la despigmentación melánica, ya que se presentó como un procedimiento con menor morbidad y buen resultado postoperatorio.
