Uso da terapia a laser de baixa potência como coadjuvante no levantamento de seios maxilares na implantodontia / Use of low-power laser therapy as an adjuvant in elevating maxillary sinuses in implantology

A busca por implantes dentários se tornou uma prática odontológica muito utilizada, no entanto, existem pacientes que não apresenta volume ósseo suficiente para receber o implante. A terapia a laser de baixa potência (LTBP) contém uma resposta relevante no desempenho dessas fases primárias da estabilidade da osseointegração. Dessa maneira, o estudo tem como objetivo analisar a eficiência e aplicação do LTBP em levantamento de seio maxilar dentro da implantodontia, ressaltando seus benefícios, limitações, importância e impacto para saúde bucal. Tratou-se de uma revisão narrativa de literatura, com seleção de artigos científicos encontrados nas bases de dados: PubMed, LILACS, BVS, SciELO e Google Acadêmico, sem período definido de publicação, com cruzamento dos Descritores em Ciências e Saúde (DeCS) e adotados os operadores booleanos "AND" e "OR". A quantidade ideal de altura óssea é importante para a reabilitação com implantes dentários e, em certos casos, o levantamento de seio maxilar se torna necessário expandir a altura de osso residual na maxila por meio da elevação da membrana de Schneider. Sendo assim, a literatura apresenta diversas formas para utilizar o LTBP na implantodontia, desde o início da limpeza na região que vai receber o implante até sua realização cirúrgica, a qual apresenta ótima melhoria na ação de osseointegração, amenizando desconfortos referentes ao pós-operatório e planejamento cirúrgico. Apesar de existir estudos controversos sobre a aplicação do LTBP no levantamento de seio maxilar para colocação de implantes, fica evidente que sua utilização obtém resultados efetivos no processo de cicatrização e reparação dos tecidos ósseos.

The search for dental implants has become a widely used dental practice; however, there are patients who do not have sufficient bone volume to receive the implant. Low-level laser therapy (LLLT) contains a relevant response in the performance of these primary phases of osseointegration stability. Thus, the study aims to analyze the efficiency and application of LLLT in maxillary sinus lifting within implantology, highlighting its benefits, limitations, importance, and impact on oral health. It was a narrative literature review, with the selection of scientific articles found in the databases: PubMed, LILACS, BVS, SciELO, and Google Scholar, without a defined publication period, with the crossing of the Health Sciences Descriptors (DeCS) and the adoption of the boolean operators "AND" and "OR." The ideal amount of bone height is important for rehabilitation with dental implants, and in certain cases, maxillary sinus lifting becomes necessary to expand the residual bone height in the maxilla through elevation of the Schneiderian membrane. Thus, the literature presents various ways to use LLLT in implantology, from the beginning of cleaning in the region that will receive the implant to its surgical implementation, which shows excellent improvement in osseointegration action, alleviating discomfort related to postoperative and surgical planning. Although there are controversial studies on the application of LLLT in maxillary sinus lifting for implant placement, it is evident that its use yields effective results in the healing and repair process of bone tissues.

Uso do laser de baixa potência para o tratamento de parestesia: uma revisão de literatura / Use of low-level laser to treat paresthesia: a literature review

Introdução: A parestesia é uma neuropatia que afeta a função sensorial. O Laser de Baixa Potência (LBP), por sua vez, apresenta propriedades analgésicas, bioestimuladoras e reparadoras. Objetivo: Realizar um levantamento na literatura científica sobre os aspectos gerais e benefícios do LBP no manejo terapêutico da parestesia, além de identificar a classificação e métodos de obtenção do diagnóstico desta condição. Materiais e Métodos: Tratou-se de uma revisão narrativa da literatura através da busca nas plataformas PubMed, SciELO, LILACS e Google Schoolar. Após o cruzamento dos descritores com os operadores booleanos e aplicação dos critérios de inclusão/exclusão, 26 estudos foram incluídos. Resultados: A parestesia pode ser classificada em neuropraxia, axonotmese e neurotmese, subdivididas em Grau I ao V. Seu diagnóstico pode ser executado através de testes subjetivos e objetivos. O LBP compreende em um dispositivo tecnológico com efeitos analgésico, anti-inflamatório e fotobiomodulador, que estimula o reparo neural. Os estudos mostram que a dosimetria nos comprimentos de onda vermelho e infravermelho, aplicação intra e extra oral, e com mais de uma sessão semanal exerce efeito modulatório positivo do reparo neural, com retorno progressivo da atividade sensitiva. Além disso, os estudos trazem uma ampla variação no número de pontos de aplicação, bem como no tempo de irradiação e quantidade de sessões, em virtude da extensão e tempo de diagnóstico da parestesia. Considerações finais: Apesar da alta complexidade da parestesia, o LBP exerce efeitos benéficos através do retorno da sensibilidade parcial ou total, além de ser um dispositivo bem tolerado pelo organismo e minimamente invasivo.

Introduction: Paresthesia is a neuropathy that affects sensory function. The Low-Level Laser (LLL), in turn, has analgesic, biostimulating and reparative properties. Purpose: Carry out a survey at the scientific literature on the general aspects and benefits of LLL in the therapeutic management of paresthesia in addition to identifying the classification and methods for obtaining a diagnosis of this condition. Materials and Methods: It was a narrative literature review through search in platforms PubMed, SciELO, LILACS and Google Schoolar. After crossing the descriptors with boolean operators and applying the inclusion/exclusion criteria, 26 articles were included in this study. Results: Paresthesia can be classified into neuropraxia, axonotmesis and neurotmesis, subdivided into Grades I to V. Its diagnostic can be carried out through subjective and objective tests. The LLL consists in a technological device with analgesic, anti-inflammatory and photobiomodulatory effects, which stimulates neural repair. Studies show that LLL in dosimetry at red and infrared wavelengths with intra and extra oral application and with more than one-week use exerts a positive modulatory effect on neural repair, with a progressive return of sensory activity. Furthermore, the studies show a wide variation in the number of application points, as well as the irradiation time and number of sessions, due to the extent and time of diagnosis of paresthesia. Final Considerations: Despite the high complexity of paresthesia, the LLL has beneficial effects through the return of partial or total sensitivity in addition being a device well tolerated by the body and minimally invasive.

A comparative analysis of the effectiveness of laser correction with a mechanical and laser microkeratome for myopia

ABSTRACT Purpose: Myopia, or nearsightedness, is one of the most common eye conditions worldwide. However, a comparison of the effectiveness of different laser-assisted interventions is lacking. Thus, we aimed to compare the efficacy and safety of LASIK and IntraLASIK in addressing myopia. Methods: The study was conducted in two ophthalmology clinics in Beijing, China, in 2022. A total of 84 patients (152 eyes) with different degrees of myopia were examined and underwent LASIK (n=46, 80 eyes) or IntraLASIK (n=38, 72 eyes). Keratometry, corneal topography, pachymetry, visual acuity evaluation, and corneal biomechanical analysis were performed before and after the intervention. Results: IntraLASIK produced more precise flaps than LASIK, with deviations of <8 mm and 0.1 mm from the intended thickness and diameter, respectively. LASIK resulted in nonuniform flaps, with thickness deviations of 5-86 mm. IntraLASIK demonstrated a superior efficacy for patients with severe myopia and thin corneas, with a mean spherical equivalent of 0.9 D at 6 months compared to the 1.4 D for LASIK. Approximately 91% and 83% of the patients with mild to moderate and severe myopia, respectively, achieved results within ± 0.49 D from the refractive target with IntraLASIK. Conclusions: Corneal hysteresis and corneal resistance factor decreased with an increase in laser intensity, and they decreased faster with thinner corneas. Thus, IntraLASIK is more useful than LASIK in patients with thin corneas and severe myopia.

Comparison of safety and effectiveness of micropulse transscleral cyclophotocoagulation and "slow cook" diode laser transscleral cyclophotocoagulation in patients with refractory open-angle glaucoma

ABSTRACT Purpose: This study aimed to compare the safety and effectiveness of intraocular pressure reduction between micropulse transscleral cyclophotocoagulation and "slow cook" transscleral cyclophotocoagulation in patients with refractory primary open-angle glaucoma. Methods: We included patients with primary open angle glaucoma with at least 12 months of follow-up. We collected and analyzed data on the preoperative characteristics and postoperative outcomes. The primary outcomes were a reduction of ≥20% of the baseline value (criterion A) and/or intraocular pressure between 6 and 21 mmHg (criterion B). Results: We included 128 eyes with primary open-angle glaucoma. The preoperative mean intraocular pressure was 25.53 ± 6.40 and 35.02 ± 12.57 mmHg in the micropulse- and "slow cook" transscleral cyclophotocoagulation groups, respectively (p<0.001). The mean intraocular pressure was reduced significantly to 14.33 ± 3.40 and 15.37 ± 5.85 mmHg in the micropulse- and "slow cook" transscleral cyclophotocoagulation groups at the last follow-up, respectively (p=0.110). The mean intraocular pressure reduction at 12 months was 11.20 ± 11.46 and 19.65 ± 13.22 mmHg in the micropulse- and "slow cook" transscleral cyclophotocoagulation groups, respectively (p<0.001). The median preoperative logMAR visual acuity was 0.52 ± 0.69 and 1.75 ± 1.04 in the micropulse- and "slow cook" transscleral cyclophotocoagulation groups, respectively (p<0.001). The mean visual acuity variation was −0.10 ± 0.35 and −0.074 ± 0.16 in the micropulse- and "slow cook" transscleral cyclophotocoagulation, respectively (p=0.510). Preoperatively, the mean eye drops were 3.44 ± 1.38 and 2.89 ± 0.68 drugs in the micropulse- and "slow cook" transscleral cyclophotocoagulation groups, respectively (p=0.017), but those were 2.06 ± 1.42 and 1.02 ± 1.46 at the end of the study in the "slow cook" and micropulse transscleral cyclophotocoagulation groups, respectively (p<0.001). The success of criterion A was not significant between both groups. Compared with 11 eyes (17.74%) in the "slow cook" transscleral cyclophotocoagulation group, 19 eyes (28.78%) in the micropulse transscleral cyclophotocoagulation group showed complete success (p=0.171). For criterion B, 28 (42.42%) and 2 eyes (3.22%) showed complete success after micropulse- and "slow cook" transscleral cyclophotocoagulation, respectively (p<0.001). Conclusion: Both techniques reduced intraocular pressure effectively.

In-office Laryngeal Procedures: a Modern Perspective for Vocal Fold Interventions

Introduction: The purpose of this article is to discuss in-office laryngeal procedures as an alternative to surgical intervention under general anesthesia. In-office procedures have become more common due to technological advancements. As a result, these approaches are less invasive and more patient-friendly, with increased pain tolerance and reduced procedure time and cost. Methods: We conducted a thematic analysis of published reports regarding the best known and performed in-office laryngeal interventions. Three questions guided our analysis: What laryngological procedures can be performed in the office setting? What are the advantages of in-office laryngology procedures compared to operating room surgical procedures? Why aren't more in-office procedures performed in some Latin American countries? Discussion: Despite being performed more frequently, there is still controversy whether in-office procedures should be performed as often due to the risk of complications. Furthermore, procedures that are done in the office setting are more popular in some countries than in others, even though their benefit has been well demonstrated. This article describes various in-office procedures, including biopsy, vocal fold injections, and laser surgery. We also discuss what factors might contribute to having office-procedures being performed more frequently in some countries than others. Conclusion: Awake interventions offer numerous benefits, including shorter procedure time, reduced costs, and lower patient morbidity. These advantages have significantly transformed the treatment of laryngeal diseases in modern laryngology practice in a global manner.

Introducción: El propósito de este artículo es discutir los procedimientos laríngeos en el consultorio como una alternativa a la intervención quirúrgica bajo anestesia general. Los procedimientos en consultorio se han vuelto más comunes debido a los avances tecnológicos. Como resultado, estos enfoques son menos invasivos y más amigables para el paciente, con mayor tolerancia al dolor y reducción del tiempo y costo del procedimiento. Métodos: Realizamos un análisis temático de los informes publicados sobre las intervenciones laríngeas más conocidas y realizadas. Tres preguntas guiaron nuestro análisis: ¿Qué procedimientos laringológicos se pueden realizar en el consultorio y cuales sin los más frecuentes?, ¿cuáles son las ventajas de los procedimientos laringológicos fuera del quirófano frente a los que se realizan bajo anestesia general?, ¿por qué no se realizan más procedimientos laringológicos en el consultorio en la mayoría de los países en Latinoamérica? Discusión: A pesar de que se realizan con mayor frecuencia, aún existe controversia sobre si los procedimientos en consultorio deben realizarse con tanta frecuencia debido al riesgo de complicaciones. Además, los procedimientos que se realizan en el consultorio son más populares en algunos países que en otros, aunque sus beneficios han sido bien demostrados. Este artículo describe varios procedimientos en el consultorio, incluida la biopsia, las inyecciones de cuerdas vocales y la cirugía con láser. También se discutieron los factores que podrían contribuir a que los procedimientos en el consultorio se realicen con más frecuencia en algunos países que en otros. Conclusión: Las intervenciones con pacientes despiertos ofrecen numerosos beneficios, incluido un tiempo de procedimiento más corto, costos reducidos y una menor morbilidad para el paciente. Estas ventajas han transformado significativamente el tratamiento de las enfermedades laríngeas en la práctica de la laringología moderna a nivel mundial.

Fotocoagulación láser guiada por ultrasonido para el tratamiento del secuestro broncopulmonar fetal. Reporte de dos casos exitosos en Venezuela / Ultrasound-guided laser photocoagulation for the treatment of fetal bronchopulmonary sequestration. Report of two successful cases in Venezuela

El secuestro broncopulmonar es una malformación del aparato respiratorio que consiste en tejido bronquial y pulmonar no funcionante, separado del árbol tráqueo-bronquial y alimentado por un vaso sanguíneo proveniente de la circulación sistémica. La incidencia es de 1 por cada 5000 nacimientos, comprende entre 0,15 % y 6,45 % de las patologías pulmonares. El pronóstico es, generalmente, favorable, reportándose regresión espontánea de la lesión en 50 % a 75 % de los pacientes. Puede ocasionar efecto de masa, comprimiendo el corazón y el pulmón hasta generar cambios hemodinámicos y falla cardíaca. Hay múltiples procedimientos para el tratamiento y manejo, principalmente en casos de gran tamaño y fetos hidrópicos, para mejorar el pronóstico perinatal. Se presentan los dos primeros casos de secuestro broncopulmonar tratados en Venezuela mediante fotocoagulación láser del vaso nutricio y su evolución perinatal, con sobrevida del 100 % y sin ninguna complicación registrada en el periodo perinatal(AU)

Bronchopulmonary sequestration is a malformation of the respiratory system consisting of non-functioning bronchial and pulmonary tissue, separated from the tracheo-bronchial tree and fed by a blood vessel from the systemic circulation. The incidence is 1 in 5000 births, ranging from 0.15% to 6.45% of pulmonary pathologies. The prognosis is generally favorable, with spontaneous regression of the lesion reported in 50% to 75% of patients. It can cause mass effect, compressing the heart and lung to the point of generating hemodynamic changes and heart failure. There are multiple procedures for treatment and management, mainly in large cases and hydropic fetuses, to improve perinatal prognosis. We present the first two cases of bronchopulmonary sequestration treated in Venezuela by laser photocoagulation of the nutrient vessel and their perinatal evolution, with 100% survival and without any complications recorded in the perinatal period(AU)

The integration of surgical and dermatological techniques in the treatment of cutaneous aging: multidisciplinary approaches and clinical outcomes - a comprehensive systematic review of current literature

This comprehensive review explores the integration of surgical and dermatological techniques in treating cutaneous aging, highlighting the evolution of anti-aging strategies towards more refined and less invasive methods. As aging skin results from a combination of intrinsic and extrinsic factors, leading to structural and physiological changes, dermatology has advanced to offer multifaceted treatment approaches. We aimed to review advances and evolution in surgical interventions such as facelifts and blepharoplasty. We will discuss noninvasive and minimally invasive techniques, such as Ultherapy and fat grafting, which are widely used and are the best alternatives to traditional surgery. Other techniques, such as thread lifts and novel materials like polydioxanone (PDO) and polylactic acid (PLA) threads, are also reliable techniques for minimally invasive facial rejuvenation.

Comparison of the clinical effectiveness of Class IV Laser therapy and therapeutic ultrasound in patients with chronic neck pain: a randomized controlled trial / Comparação da eficácia clínica da terapia a laser Classe IV e do ultrassom terapêutico em pacientes com dor cervical crônica: um estudo controlado e randomizado

INTRODUCTION: Chronic neck pain (CNP) is a common musculoskeletal problem that affects a large proportion of the population and lasts longer than three months. It has a high cost in terms of life, disability, and healthcare. Several modalities have effectively provided immediate and long-term relief for CNP; however, the comparative clinical effectiveness of these modalities is limited. OBJECTIVES: The study aimed to determine the clinical effectiveness of Class IV Laser therapy and Therapeutic Ultrasound (TUS) in patients with CNP. METHODS AND MATERIALS: Forty-four patients with CNP of both genders were recruited from an age range of 20­45 years from the Department of Musculoskeletal Physiotherapy of Maharishi Markandeshwar Institute of Physiotherapy, MM(DU), Ambala, India. They were divided into two groups at random: the LASER group A (n = 22) and the TUS group B (n = 22). The intervention duration was 2 weeks with 6 treatment sessions. Pre- and post-treatment outcome measures were assessed with the Visual Analog Scale (VAS), Algometer, Goniometer, and Neck Disability Index (NDI) questionnaires at baseline and after 2 weeks of intervention. The LASER group received a target dose of 10 joules per cm2 at a power of 10 watts, with a continuous dosage frequency. The TUS group underwent a continuous mode ultrasound (3 MHz, 1 W/cm2) for 6 minutes. The Shapiro-Wilk test was used to assess the normality of the data. For parametric and non-parametric data analysis within the group, the paired t-test and Wilcoxon signed rank were used. The independente t-test and Mann-U Whitney test were used for the group comparison of parametric and non-parametric data, respectively. RESULTS: In both groups, there was a significant improvement in all the outcome measures (p<0.001). There was a statistically significant difference between the two interventions in VAS, Pain Pressure Threshold (PPT), and NDI (p<0.05). CONCLUSION: Class IV Laser therapy is clinically more effective than therapeutic ultrasound in treating patients with chronic neck pain.

INTRODUÇÃO: A dor cervical crônica (DCC) é um problema musculoesquelético comum que afeta uma grande proporção da população e dura mais de três meses. Ela tem um alto custo em termos de vida, incapacidade e assistência médica. Várias modalidades têm proporcionado alívio imediato e de longo prazo para a dor cervical crônica; entretanto, a eficácia clínica comparativa dessas modalidades é limitada. OBJETIVOS: O objetivo do estudo foi determinar a eficácia clínica da terapia a laser de classe IV e do ultrassom terapêutico (UST) em pacientes com DCC. MÉTODOS E MATERIAIS: Quarenta e quatro pacientes com DCC de ambos os sexos, em uma faixa etária de 20 a 45 anos, foram recrutados do Departamento de fisioterapia musculoesquelética do Instituto de Fisioterapia Maharishi Markandeshwar, MM (DU), Ambala, Índia. Eles foram divididos em dois grupos de forma aleatória: o grupo LASER A (n = 22) e o grupo UST B (n = 22). A duração da intervenção foi de 2 semanas com 6 sessões de tratamento. As medidas de resultado pré e pós-tratamento foram avaliadas com os questionários Escala Visual Analógica (EVA), Algometer, Goniometer e Índice de Incapacidade do Pescoço (IIP) na linha de base e após 2 semanas de intervenção. O grupo LASER recebeu dose alvo de 10 joules por cm2 na potência de 10 watts, com frequência de dosagem contínua. O grupo UST foi submetido a ultrassom em modo contínuo (3 MHz, 1 W/cm2) por 6 minutos. O teste de Shapiro-Wilk foi utilizado para avaliar a normalidade dos dados. Para análise dos dados paramétricos e não paramétricos dentro do grupo, foram utilizados o teste t pareado e o posto sinalizado de Wilcoxon. O teste t independente e o teste Mann-U Whitney foram utilizados para comparação de grupos para dados paramétricos e não paramétricos, respectivamente. RESULTADOS: Em ambos os grupos, houve uma melhora significativa em todas as medidas de resultado (p<0,001). Houve uma diferença estatisticamente significativa entre as duas intervenções na EVA, Limiar de pressão de dor (PPT) e IIP (p<0,05). CONCLUSÕES: A terapia a laser de classe IV é clinicamente mais eficaz do que o ultrassom terapêutico no tratamento de pacientes com dor cervical crônica.

Láser CO2 vaginal, indicaciones y aplicaciones / Vaginal CO2 laser, indications and applications

El síndrome genitourinario es una entidad hoy en día cada vez más frecuente en la mujer posmenopáusica, con signos y síntomas muy característicos que llevan a la pérdida de calidad de vida de las pacientes, generados por la disminución de estrógenos. Su diagnóstico se realiza mediante una buena historia clínica, exámenes hormonales, estudios urodinámicos y de pH vaginal. Su clínica varía desde sequedad vaginal, atrofia de la misma, vaginitis a repetición, pérdida de orina al esfuerzo, nicturia y dispareunia. A los largo de los años se han protocolizado diferentes tratamientos como reemplazos hormonales, lubricantes y cirugías invasivas vaginales. Pero en los últimos años ha aparecido una nueva terapéutica de láser CO2 fraccionado. Materiales y método. Se realizó un estudio retrospectivo de seis años de evolución, entre los años 2017 y 2023, con más de 300 pacientes tratadas con tecnología láser CO2 fraccionado, con criterios de inclusión y exclusión, protocolizando 3 sesiones cada 30 días y controles hasta los 6 meses. Resultados. Para evaluar los resultados se diseñó una encuentra de satisfacción de 5 puntos, la cual fue presentada luego de cada sesión, encontrando un alto grado de satisfacción en la mejoría clínica a medida que transcurrían las sesiones, con un muy bajo índice de complicaciones. También biopsias con mejorías histológicas que demuestran resultados. Discusión. La aplicación de esta nueva tecnología láser nos abre una posibilidad terapéutica segura, rápida y efectiva para mejorar la sintomatología y calidad de vida de nuestras pacientes con síndrome genitourinario, sumando una nueva terapéutica a todo el arsenal de tratamientos médico-quirúrgicos disponibles a la fecha. Conclusiones. El síndrome genitourinario es una entidad prácticamente inevitable, con síntomas desde leves a graves, que afecta la calidad de vida personal, sexual y social. Los tratamientos hasta la fecha hormonales, tópicos o quirúrgicos han dado mediocres resultados sin estar exentos de complicaciones, por lo que la aparición de la tecnología láser CO2 fraccionada nos ha dado el plus necesario para aportar un tratamiento seguro, eficaz, con mínimas complicaciones y una curva de aprendizaje pequeña

Genitourinary syndrome is an increasingly frequent entity in postmenopausal women today, with very characteristic signs and symptoms that lead to a loss of quality of life in patients, generated by estrogen depletion, whose diagnosis is made through a good clinical history, hormonal tests, urodynamic and vaginal pH studies. Its symptoms vary from vaginal dryness, vaginal atrophy, repeated vaginitis, loss of urine on exertion, nocturia and dyspareunia. Over the years, different treatments have been protocolized, such as hormone replacements, lubricants, and invasive vaginal surgeries. But in recent years a new fractionated CO2 laser therapy has appeared. Materials and method. A retrospective study of six years of evolution was carried out, between the years 2017 and 2023, with more than 300 patients treated with fractionated CO2 laser technology, with inclusion and exclusion criteria, protocolizing 3 sessions every 30 days and controls until the 6 months. Results. To evaluate the results, a 5-point satisfaction score was designed, which was presented after each session, finding a high degree of satisfaction in the clinical improvement as the sessions progressed with a very low indication of complications. Also biopsies with histological improvements that demonstrate results. Discussion. The application of this new laser technology opens up a safe, fast and effective therapeutic possibility to improve the symptoms and quality of life of our patients with genitourinary syndrome, adding a new therapeutic option to the arsenal of medical-surgical treatments available to date. Conclusions. Genitourinary syndrome is a practically inevitable entity, with symptoms ranging from mild to severe, affecting the quality of personal, sexual and social life. The hormonal, topical or surgical treatments to date have given mediocre results, not being free of complications, so the appearance of fractionated CO2 laser technology has given us the necessary extra to provide a safe, effective treatment, with minimal complications. and a small learning curve.

Diabetes and the retinal changes in the eye: a threat to the sight

This article discusses the importance of diabetic retinopathy, an eye disease associated with diabetes, which is a systemic disease. The research question addresses the impact of diabetes on the retina of the eye through infection and clinical features. This approach is designed to improve the relationship between early diagnosis and treatment of disease, including laser surgery, corticosteroid injections, and vitrectomy. This article focuses on chronic diabetic retinopathy and eye examination recommendations in the United States and the United Kingdom. To prevent and manage diabetic retinopathy, it is recommended that diabetic patients have regular eye examinations. The results of this study include the importance of good glycaemic control, injections, photocoagulation, and vitrectomy as treatment options. Intravitreal long-acting steroids may also temporarily improve visual acuity by reducing macular oedema. However, long-term use of the drug may cause side effects and may lead to cataracts, steroid glaucoma, and endophthalmitis. It may cause reasons. A recent study of the disease in India shows that the incidence of high blood sugar and its effects on the eye is mainly diabetic retinopathy, including cataracts, neovascular glaucoma and even retinal detachment, which are very dangerous for eye health. Therefore, it is important to inform patients about this disease and perform timely screening because patients need to be informed carefully.

Acute effects of energy drink consumption on microvascular reactivity in young male volunteers at rest: a randomized trial

Energy drinks are nonalcoholic beverages whose main ingredients are sugar, taurine, and caffeine. The consumption of energy drinks is increasing worldwide, but only a few conflicting studies have investigated the vascular effects of energy drinks in young adults. The aim of this study was to evaluate microvascular reactivity before and after energy drinks consumption in young healthy male volunteers. This was a cross-sectional prospective study. Microvascular reactivity signals were evaluated in the skin of the forearm using laser speckle contrast imaging with acetylcholine (ACh) iontophoresis before and 90 and 180 min after the randomized consumption of one ED or the same volume of water (control), followed by a postocclusive reactive hyperemia (PORH) test. Thirty-two volunteers were evaluated (age: 25.4±4.3 years). Energy drink consumption prevented the rest-induced reduction in cutaneous vascular conductance over time that was observed in the control group. In the control group, there were significant reductions in microvascular vasodilation at 90 and 180 min compared to baseline (P=0.004), but this was not the case in the energy drink group (P=0.76). Our results demonstrated that the reduction in microvascular conductance associated with prolonged immobility can be prevented by the consumption of one energy drink, highlighting the vasodilator effects of this beverage in young individuals at rest. The between-study variability in terms of the brand of energy drinks and the ingested volume, as well as the method of vascular evaluation and the inclusion criteria, may explain the discrepancies among previous studies on the vascular effects of energy drinks.

Recurrence rate of oral melanotic macule treated with Q-switched alexandrite laser versus surgical excision: a retrospective cohort study / 口腔疾病防治

Objective@#To compare the recurrence rates between 755 nm Q-switched alexandrite laser (QSAL) treatment and surgical excision of oral melanotic macules (OMM).@*Methods@#This study was reviewed and approved by the Ethics Committee, and informed consent was obtained from the patients. A retrospective cohort study was designed to collect demographic and clinical characteristics and follow-up data from patients with OMM. Patients who received QSAL or surgical excision in the Department of Oral Medicine, Shanghai Ninth People's Hospital, Shanghai Jiao Tong University School of Medicine from January 2019 to August 2021 were included. The one-year recurrence rate was investigated as the primary outcome. Long-term adverse reaction rates were investigated as safety indicators. Kaplan-Meier analyses were performed to analyze the recurrence-free rates between the groups.@*Results@#A total of 57 patients were enrolled in this study. 16 patients underwent surgical excision, and 41 underwent QSAL. The baseline demographic and clinical characteristics between the groups were not significantly different. No recurrence (0%) of OMM was observed in the surgical excision group, while in the QSAL group, the macule recurred in 12 patients (29.27%). The average duration of recurrence was 6.08 months after treatment. Recurrence was not found to be associated with smoking (P = 1.000), gastrointestinal polyps (P = 1.000), longitudinal melanonychia (P = 0.187), family history (P = 0.552), treatment sessions (P = 0.567) or multiple macule lesions (P = 0.497). Compared with treatment with surgical excision, the odds ratio of recurrence for treatment with QSAL was 4.41, with a 95% confidence interval of 1.27-15.24 (P = 0.020). In the surgical excision group, 3 patients (18.75%) reported depressions and scars on the lesion, while no long-term adverse reactions (0%) were reported in the QSAL group (P = 0.019).@*Conclusion@#Compared with surgical excision, the advantage of QSAL is the low long-term adverse reaction rate, while the disadvantage is the relatively high one-year recurrence rate. It is necessary to communicate the advantages and disadvantages of the two methods with OMM patients to assist in clinical decision-making.

Corrective effect of femtosecond laser assisted laser in situ keratomileusis Xtra on patients with moderate to high myopia after 2a postoperatively / 国际眼科杂志(Guoji Yanke Zazhi)

AIM:To evaluate corrective effect and stability of corneal morphology in patients with moderate to high myopia after 2a treatment of femtosecond laser assisted laser in situ keratomileusis(FS-LASIK)Xtra.METHODS:Retrospective case-control study. A total of 30 cases(58 eyes)Patients with moderate to high myopia combined with astigmatism who planned to undergo refractive surgery in our hospital from August 2019 to August 2020 were included, and different types of surgery were performed respectively based on the relevant index of keratoconus screening in the preoperative corneal topography. They were divided into FS-LASIK group and Xtra group, with 15 cases(29 eyes)in each group. Uncorrected visual acuity(UCVA), best corrected visual acuity(BCVA), spherical equivalent(SE)and the corneal curvature of the anterior and posterior surfaces of different diameters(3, 5 and 7 mm)measured by Sirius three-dimensional corneal topography were observed preoperatively and 3 mo, 1 and 2 a postoperatively.RESULTS: The UCVA of the two groups of patients at different time points after surgery was significantly increased compared with preoperatively(both P&#x0026;#x003C;0.01), and there was no difference in UCVA and SE between the two groups(P&#x0026;#x003E;0.05). After 2 a postoperatively, residual astigmatism was -0.25-0 D in 25 eyes(86%)of the FS-LASIK Xtra group and 24 eyes(83%)of the FS-LASIK group. The actual corrected SE and expected corrected SE of both groups were positively correlated(both P&#x0026;#x003C;0.05). There were differences in corneal curvature on the surface of different diameter areas(3, 5, and 7 mm)between the two groups at 3 mo, 1, and 2 a postoperatively compared with preoperatively. After 1 and 2 a postoperatively, the corneal posterior surface curvature of the FS-LASIK Xtra group with corneal diameter of 3 and 5 mm was higher than that of the FS-LASIK group(P&#x0026;#x003C;0.05).CONCLUSIONS:FS-LASIK Xtra has good safety, efficacy and predictability in correcting patients with moderate to high myopia.

Portable Electrochemical Sensor for Sensitive Detection of Azo Dyes Sunset Yellow and Tartrazine / 分析化学

A polymethionine(p-Met)-modified laser-induced graphene(LIG)electrode was constructed and integrated with portable electrochemical workstations and handheld computer to achieve on-site,simultaneous detection of azo dyes sunset yellow(SY)and tartrazine(Tz)in environmental water.Firstly,the sensor interface with the best electrical conductivity was obtained by optimizing the laser processing parameters,and then the electrochemical responses of SY and Tz were improved by electropolymerization of methionine on the surface of LIG.Finally,a portable electrochemical sensor platform was built by connecting p-Met/LIG,a small electrochemical workstation and a handheld computer application program.Differential pulse voltammetry(DPV)was used to determine these two dyes.SY showed a good linear relationship in the concentration range of 0.2-20 μmol/L and 20-100 μmol/L,the detection limit was as low as 0.001 μmol/L.Tz showed a good linear relationship in concentration range of 0.3-40 μmol/L and 40-100 μmol/L,and the detection limits was as low as 0.005 μmol/L.p-Met/LIG also had excellent anti-interference performance and reproducibility.The portable electrochemical platform was applied to real-time detection of real water samples,and the results showed that the platform was expected to be applied in field detection of SY and Tz in real environmental water bodies.
