Rejuvenecimiento facial y láser de dióxido de carbono / Facial rejuvenation and carbon dioxide laser

El envejecimiento facial es multifactorial, la piel muestra el paso del tiempo a través de manchas, poros dilatados, arrugas, fl acidez y otras alteraciones. Si al momento de realizar un rejuvenecimiento facial no se rejuvenece también la piel, el resultado nunca será armónico o coherente. Actualmente la mejor herramienta para el rejuvenecimiento facial integral es el láser de dióxido de carbono. Si lo combinamos con el uso de microagujas y la aplicación de plasma rico en plaquetas, potenciaremos aún más los resultados

Facial aging is multifactorial, the skin shows prevents aging through spots, pores, wrinkles, gas, fl accidity and other situations. If at the time of perform facial rejuvenation we do not rejuvenate the skin, the result will never be harmonious or coherent. To this day, the best tool for refacial rejuvenation is the carbon dioxide laserand if we associate it with the use of microneedles and applications of rich plasma we are going to enhance the result

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.

Rejuvenecimiento periorbitario fisiológico / Physiological periorbital rejuvenation

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.

Métodos terapêuticos para despigmentação melânica gengival: técnica cirúrgica com lâmina de bisturi, abrasão com instrumento rotatório e ablação a laser ­ revisão de literatura / Therapeutic methods for melanin gingival depigmentation: surgical technique with a scalpel blade, abrasion with a rotary instrument and laser ablation ­ literature review

A hiperpigmentação melânica ocorre devido à deposição anormal de melanina na camada basal e suprabasal do epitélio, criando uma aparência escurecida. É fisiológica, por isso não representa dano à saúde, podendo ser apenas uma queixa estética do paciente. O objetivo deste trabalho foi realizar uma revisão de literatura narrativa sobre o uso da técnica cirúrgica com bisturi, da abrasão com instrumento rotatório e da ablação com laser como métodos para realizar a remoção da hiperpigmentação melânica gengival de etiologia fisiológica. Muitas técnicas têm sido utilizadas para fazer a despigmentação, diferentes resultados e fatores, como conforto do paciente, cuidado pós-operatório e recorrência, têm sido apresentados. A técnica cirúrgica com bisturi é considerada o padrão ouro devido aos seus bons resultados, material de fácil acesso e baixo custo. A abrasão com instrumentos rotatórios não requer nenhum equipamento ou material sofisticado, é relativamente simples e segura. E a terapia a laser é uma modalidade de tratamento eficaz, minimamente invasiva, com trans e pós-operatório confortável. Entretanto, são necessários mais estudos sobre o uso da abrasão com instrumento rotatório que acompanhem os pacientes em longo prazo e pesquisas que descrevam o uso e resultados proporcionados pelos diversos tipos de laser de alta potência. Tendo em vista a presente revisão de literatura pode-se concluir que a repigmentação não ocorre por uma média de um a dois anos. Porém, são necessários mais estudos para especificar qual técnica apresenta menor índice de repigmentação.

Melanic hyperpigmentation occurs due to abnormal deposition of melanin in the basal and suprabasal layers of the epithelium, creating a darkened appearance. It is physiological, so it does not represent harm to health, and may be just an aesthetic complaint by the patient. The objective of this work was to carry out a narrative literature review on the use of surgical technique with a scalpel, abrasion with a rotary instrument and laser ablation as methods to remove gingival melanin hyperpigmentation of physiological etiology. Many techniques have been used to perform depigmentation, different results and factors, such as patient comfort, postoperative care and recurrence, have been presented. The surgical technique with a scalpel is considered the gold standard due to its good results, easily accessible material and low cost. Abrasion with rotary instruments does not require any sophisticated equipment or material, is relatively simple and safe. And laser therapy is an effective treatment modality, minimally invasive, with comfortable trans and postoperative. However, more studies are needed on the use of abrasion with a rotary instrument to monitor patients in the long term and research that describe the use and results provided by the different types of high-power lasers. In view of the present literature review, it can be concluded that repigmentation does not occur for an average of one to two years. However, further studies are needed to specify wich technique has the lowest rate of repigmentation.

Laser therapy for genitourinary syndrome of menopause: systematic review and meta-analysis of randomized controlled trial

Abstract Objective: This meta-analysis of randomized controlled trials (RCTs) aimed to update evidence on the effectiveness and safety of laser therapy for treating genitourinary syndrome of menopause (GSM). Data sources: Manuscripts published until May 2023 were systematically searched in PubMed; Embase; Scopus; Web of Science; CENTRAL; CINAHL; and clinical trial databases (www.trialscentral.org, www.controlled-trials.com, and clinicaltrials.gov), with no language and year of publication restriction. Studies selection: RCTs with women diagnosed with GSM, and the intervention was vaginal laser therapy (CO2-laser or Er: YAG-laser) comparing with placebo (sham therapy), no treatment or vaginal estrogen therapy. Data collection: Two authors evaluated the publications for inclusion based on the title and abstract, followed by reviewing the relevant full-text articles. Disagreements during the review process were addressed by consensus, with the involvement of a third author. Data synthesis: Twelve RCTs, representing a total of 5147 participants, were included in this review. Vaginal health index (VHI) significantly improved in the carbon dioxide laser (CO2-laser) therapy group (MD=2.21; 95% CI=1.25 to 3.16), while dyspareunia (MD=−0.85; 95% CI=−1.59 to −0.10), dryness (MD=−0.62; 95% CI=−1.12 to −0.12) and burning (MD= −0.64; 95% CI=−1.28 to −0.01) decreased. No serious adverse effects were reported. Conclusion: CO2-laser increases VHI score and decreases dyspareunia, dryness and burning, especially when compared to sham-laser. However, the certainty of the evidence is low, thus preventing the recommendation of laser therapy for GSM management.

Terapia de fotobiomodulação em lesões por pressão relacionada a dispositivos médicos: relato de caso em lábio de um paciente adulto / Photobiomodulation therapy for medical device-related pressure injuries: a case report of an adult with lip involvement

Lesão por pressão relacionada a dispositivos médicos é uma complicação bastante comum e geralmente oriunda da fixação do dispositivo utilizado na intubação endotraqueal para ventilação mecânica. Desta forma, o presente estudo reportou o caso de um paciente do sexo masculino, 65 anos, leucoderma, internado em uma unidade de terapia intensiva, e que desenvolveu lesão ulcerada na região de fixação do dispositivo utilizado para intubação orotraqueal. Após alívio da pressão local exercida, terapia de fotobiomodulação foi proposta como única estratégia para cicatrização da lesão e diminuição do edema. Após 3 sessões diárias foi possível observar excelente curso de reparação tecidual e remissão dos sinais flogísticos. De acordo com o presente caso, a terapia de fotobiomodulação parece ser bastante eficiente para o tratamento de lesões por pressão relacionada a dispositivos médicos(AU)

Medical device-related pressure injuries are very common complications and usually arise from the fixation of the device used in endotracheal intubation for mechanical ventilation. Thus, the present study reports a case of a Caucasian male patient, 65 years old, who was admitted to an intensive care unit and developed later an ulcerated lesion on the region of fixation of the device used for orotracheal intubation. After relieving the local pressure exerted, photobiomodulation therapy was proposed as the only strategy for wound healing and edema reduction. After 3 daily sessions, it was possible to note an excellent tissue repair course and remission of phlogistic signs. According to the present case, photobiomodulation therapy appears to be a quite efficient treatment strategy for medical device-related pressure injuries(AU)

Tratamento de lesão periradicular, de origem endodôntica, com auxílio de laserterapia: uma revisão sistemática da literatura e apresentação se caso clínico / Treatment of periradicular injury, of endodontic origin, with the aid of laser therapy: a systematic review of the literature and presentation if clinical case

É sabido que a cavidade oral é a porta de entrada para muitos microrganismos e que possui alguns gêneros de bactérias que quando se associam ou proliferam em excesso, com a falta de higienização correta, fatores ambientais e imunológicos podem causar danos em algumas partes dos dentes como no tecido pulpar e canais radiculares. Neste sentido, a endodontia tem sido capaz de tratar pessoas com problemas dentários em fases muito precoces como as medidas profiláticas até casos infeciosos que afetam a polpa dos dentes causando as lesões perirradiculares que são infecções causadas por microrganismos, Para tanto, é necessário que a odontologia ofereça transformações positivas por meio de técnicas que sejam mais previsíveis para os tratamentos. A literatura tem indicado o uso da laserterapia como técnica auxiliar para o tratamento endodôntico pelo seu potencial mínimo invasivo, preciso e eficaz em menor tempo de cura de patologias orais como as lesões perirradiculares. Este estudo pretendeu abordar a importância da laserterapia sobre as variáveis patológicas de pacientes com lesão perirradiculares. Para realiza-lo foi necessário buscar na literatura estudos que associem este tipo de tratamento e sua eficiência no tratamento desta patologia. Para realizar esta pesquisa foi necessário buscar dados na literatura que tratam sobre o tema para investigar o tempo indicado ao tratamento com a laserterapia bem como o estágio em que as lesões podem ser tratadas com auxílio deste método. Corroborando com o estudo apresentamos um caso clínico(AU)

It is known that the oral cavity is the gateway to many microorganisms and that it has some genera of bacteria that when they associate or proliferate in excess, with the lack of correct hygiene, environmental and immunological factors can cause damage in some parts of the teeth such as in pulp tissue and root canals. In this sense, endodontics has been able to treat people with dental problems at very early stages such as prophylactic measures to infectious cases that affect the pulp of teeth causing perirradicular lesions that are infections caused by microorganisms, therefore, it is necessary that dentistry offer positive transformations through techniques that are more predictable for treatments. The literature has indicated the use of laser therapy as an auxiliary technique for endodontic treatment for its minimal invasive, precise and effective potential in shorter time of cure of oral pathologies such as perirradicular lesions. This study aimed to address the importance of laser therapy on the pathological variables of patients with perirradicular lesions. To accomplish this, it was necessary to seek studies in the literature that associate this type of treatment and its efficiency in the treatment of this pathology. To carry out this research it was necessary to seek data in the literature that deal with the subject to investigate the time indicated for treatment with laser therapy as well as the stage at which lesions can be treated with the aid of this method. Corroborating the study, we present a clinical case(AU)

Surgical Treatment of Oral Fibrous Hyperplasia with Diode Laser: An Integrative Review / Tratamiento Quirúrgico de la Hiperplasia Fibrosa Oral con Láser de Diodo: Una Revisión Integradora

This study aimed to carry out an integrative review of the use of diode lasers in the treatment of oral fibrous hyperplasia in order to observe surgical efficacy, healing process, and main microscopic findings. The following databases-PubMed/MEDLINE, Embase, Virtual Health Library, Scopus, Web of Science, and gray literature-were searched without regard to the time of year or language. Diode laser treatment cases described in case reports and case series were included, but those who did not undergo microscopic analysis to confirm the diagnosis or who did not provide postoperative information were excluded. Twelve studies (64 patients) were included. Prevalence was observed for females (68.75 %, n=44). In view of the diagnosis, there was a prevalence of focal fibrous hyperplasia (79.68 %, n=51), followed by inflammatory fibrous hyperplasia (20.31 %, n=13). For surgical removal, a diode laser was used with a wavelength ranging from 808 to 960 nm, in continuous mode, and an average power of 2830 mW. In general, there were no intercurrences in the trans and postoperative periods and wound healing occurred by second intention, with excellent evolution. High-powered diode lasers can be an excellent therapeutic option for oral hyperplastic lesions. Long-term clinical trials should be conducted to determine laser setting parameters in various oral lesions.

El objetivo de este estudio fue realizar una revisión integradora sobre el uso del láser de diodo en el tratamiento de la hiperplasia fibrosa oral, con el fin de visualizar la eficacia quirúrgica, el patrón de cicatrización y el análisis de los principales resultados microscópicos. Se realizó una búsqueda sin restricciones de año e idioma en PubMed/MEDLINE, Embase, Virtual Health Library, Scopus, Web of Science y literatura gris. Se incluyeron reportes de casos y series de casos que brindaron información sobre pacientes diagnosticados con lesiones hiperplásicas orales tratados con láser de diodo, excluyendo aquellos a los que no se les había realizado análisis microscópico para confirmar el diagnóstico, así como aquellos que no brindaron información postoperatoria. Se incluyeron doce estudios (64 pacientes). Se observó prevalencia en el sexo femenino (68,75 %, n=44). Ante el diagnóstico, predominó la hyperplasia fibrosa focal (79,68 %, n=51), seguida de la hiperplasia fibrosa inflamatoria (20,31 %, n=13). Para la remoción quirúrgica se utilizó un láser de diodo con una longitud de onda de 808 a 960 nm, en modo continuo, y una potencia promedio de 2830 mW. En general, no hubo intercurrencias en el trans y postoperatorio y la cicatrización de la herida ocurrió por segunda intención, con excelente evolución. El uso de láseres de diodo de alta potencia puede ser una excelente alternativa terapéutica para las lesiones hiperplásicas orales. Se deben realizar más estudios clínicos a largo plazo para determinar los parámetros de ajuste del láser en diferentes lesiones orales.

Parestesia do nervo alveolar inferior decorrente de procedimentos cirúrgicos e suas formas de tratamentos / Paresthesi of the lower alveolar nerve resulting from surgical procedures and its forms of treatment

Nas cirurgias odontológicas é possível que ocorra alguns acidentes ou complicações que podem interferir no dia a dia do paciente. A lesão do nervo alveolar inferior é uma complicação decorrente de cirurgias orais que podem causar um distúrbio de sensibilidade transitória ou persistente, na região do lábio inferior e na região delimitada do forame mentoniano e hemi-arco da mucosa. O diagnóstico da parestesia pode ser feito através de testes mecanoceptivos e nocioceptivos em que o profissional escolherá para qual melhor se adapte no paciente. O objetivo do presente trabalho foi abordar por meio de uma revisão de literatura as formas de diagnóstico e tratamento da parestesia do nervo alveolar inferior decorrentes de cirurgias orais. As bases de dados utilizadas para confecção desta revisão são encontradas nas bibliotecas virtuais eletrônicas: BVS (Biblioteca Virtual em Saúde), LILACS (Literatura Latino-Americana e do Caribe em Ciências da Saúde) e Pubmed. Como critério de inclusão foram selecionados artigos publicados de 2012 a 2022 em língua inglesa, portuguesa e espanhola. Após a leitura do título e resumo dos resultados da pesquisa e aplicação dos critérios de inclusão e exclusão dentre eles foram excluídos 883, pois não se enquadravam no nosso critério de inclusão. No final, foram selecionados 13 estudos por meio de base de dados, que serviram de base para esta revisão. Concluímos que as formas de tratamento para a parestesia na literatura, são um pouco escassas e conflitantes, mas relata que o uso da laserterapia e acupuntura tem sido uma forma de tratamento com um bom índice de sucesso, e para os casos que não sejam suficientes tais tratamentos, pode-se optar por uma cirurgia(AU)

In dental surgeries it is possible to have some accidents or complications that can interfere with the patient's day. Injury to the inferior alveolar nerve is a complication resulting from oral surgeries that can cause a disturbance of sensitivity that can be transient or persistent in the region of the lower lip and in the delimited region of the mental foramen and hemiarch of the mucosa. The diagnosis of paresthesia can be made through mechanoceptive and nocioceptive tests that the professional will choose, which best suits the patient. The objective of the present work is to approach, through a literature review, the forms of diagnosis and treatment aimed at inferior alveolar nerve paresthesia resulting from oral surgeries. The databases used for this review are found in the virtual electronic libraries: VHL (Virtual Health Library), LILACS (Latin American and Caribbean Literature on Health Sciences) and Pubmed. As inclusion criteria, articles published from 2012 to 2022 in English, Portuguese and Spanish were selected. After reading the title and summary of the research results and applying the inclusion and exclusion criteria, 883 were excluded, as they did not meet our inclusion criteria. In the end, 13 studies were selected from the database, which served as the basis for this review. We conclude that the forms of treatment for paresthesia in the literature are a little scarce and conflicting, but it reports that the use of laser therapy and acupuncture has been a form of treatment with a good success rate, and for cases that are not enough, such treatments, one can opt for surgery(AU)

Terapia a laser de alta intensidade para rigidez muscular dos isquiotibiais: fundamentação e desenho do estudo para estudo controlado randomizado simples-cego / High-intensity laser therapy for hamstring muscle tightness: rationale and study design for a single-blinded randomized controlled trial

CONTEXTO: Sentar-se por muito tempo e um estilo de vida sedentário podem resultar em encurtamento dos isquiotibiais. Um declínio na atividade física regular pode levar a uma diminuição da flexibilidade do músculo em um adulto mais jovem. Aumentar a flexibilidade dos músculos isquiotibiais pode diminuir as possibilidades de lesões e prevenir a dor lombar. A aplicação da terapia a laser de alta intensidade (TLAI) tem demonstrado inúmeros benefícios para diversas condições. No entanto, até o momento, não hápesquisas publicadassobre a eficácia dessaterapia para melhorar o comprimento dos músculos isquiotibiais em adultos jovens saudáveis. Este artigo descreve o protocolo de estudo para investigar os benefícios do TLAI no tratamento da rigidez muscular dos isquiotibiais em adultos jovens. MÉTODOS: 136 indivíduos jovens saudáveis serão recrutados, pelo método de amostragem intencional, para participar de um estudo randomizado, simplescego e controlado por simulação. Os participantes recrutados serão divididos aleatoriamente em dois grupos, o grupo TLAIativo e o grupo TLAI placebo. A duração do tratamento será de 8 a 10 minutos por sessão em ambos os membros inferiores, em dias alternados, durante duas semanas. O teste de extensão ativa do joelho e o teste de sentar e tocar são as medidas de resultado que serão registradas na linha de base, no final do período pós-intervenção de 2 semanas. O valor de p ≤0,05 será considerado estatisticamente significativo. DISCUSSÃO: Os resultados do estudo fornecerão os dados para determinar se aTLAI seria uma futura intervenção não farmacológica não invasiva para reduzir a tensão muscular dos isquiotibiais em adultos jovens.

BACKGROUND: Prolonged sitting and a sedentary lifestyle may result in hamstring shortness. A decline in regular physical activity could lead to a decrease in the flexibility of the muscle in a younger adult. Increasing hamstring muscle flexibility could decrease the possibility of injuries and prevent low back pain. The application of high-intensity laser therapy (HILT) has proved to be innumerable benefits for many conditions. However, to date, no published research is available on the effectiveness of this therapy in improving hamstring muscle length in healthy young adults. This article describes the study protocol for investigating the benefits of HILT in treating hamstring muscle tightness among young adults. METHODS: 136 healthy young individuals will be recruited, by purposive sampling method, to participate in a randomized, single-blinded, sham-controlled study. Recruited participants will be randomly divided into two groups, the active HILT group, and the sham HILT group. The treatment duration will be 8-10 minutes per session, on both lower limbs, for alternate days a week, for two weeks. The active knee extension test and sit-toe and touch test are the outcome measures that will be recorded at baseline, end of the 2-week post-intervention period. The p-value ≤0.05 will be considered statistically significant. DISCUSSION: The study findings will provide the data to determine whether HILT would be a future non-pharmacological non-invasive intervention to reduce hamstring muscle tightness among young adults. TRIAL REGISTRY: Clinical Trials Registry NCT05077761.

Evaluation of teaching low intensity laser in perspective dentist

Search knowledge dentist front surgeon to low intensity laser through a questionnaire. They were selected randomly in the city of Juiz de Fora and region 91 Dental Surgeons of Minas Gerais. These employees were sent during the months from July to October 2013, a standard form printed with questions about laser education assessment of low intensity. Of the 91 participants, 42 (46.2%) were female and 49 (53.8%) were male. Fifty-seven (62.6%) had dental public institution of higher education; 32 (35.2%) attended a private institution and 2 (2.2%) did not report this data. Eighty-nine dentists reported the time of graduation, and this varied with a minimum of 1 year and a maximum of 38 years of training, the average being 11 years and this is the standard deviation of 10.7. The age of these professionals is on average thirty-five years, ranging from twenty-two years to sixty-five years of age and the standard deviation of this is 10.8. The distribution according to academic title was: 35 dentists (38.5%) had a degree in dentistry; 13 (14.3%) were specialists; 14 (15.4%) had master's and 4 (4.4%) doctorate. 25 (27.5%) did not report the academic title. The most relevant mentioned specialties were general practitioner, endodontics and implantology. We can conclude that the Juiz de Fora dentist - MG and region makes little use of laser therapy and this is mainly due to little knowledge acquired at the undergraduate and graduate education.

Application and value of intravascular ultrasound for excimer laser ablation combined with drug-coated balloon in the treatment of lower limb arteriosclerotic obliterans / 中华外科杂志

Objective: To examine the value of intravascular ultrasound (IVUS) for excimer laser ablation (ELA) combined with drug-coated balloon (DCB) in treating lower limb arteriosclerotic obliterans (ASO). Methods: As a prospective case series study, patients who underwent ELA combined with DCB for lower limb ASO with the guidance of IVUS from September 2021 to March 2022 at Department of Vascular Surgery, Zhongshan Hospital, Fudan University were enrolled prospectively. Lesion characteristics, procedure-related outcomes and complications were collected. The therapy outcomes were compared with baseline data by paired t test. Results: There were 8 males and 2 females, aged (72.0±5.9) years (range: 61 to 81 years). Of all the 11 lesions, there were 8 lesions in superficial femoral artery and 3 in popliteal artery. The lesion length was (7.0±2.4) cm (range: 3.2 to 9.8 cm). There were 4 chronic totally occlusion and 7 severe stenosis. All patients underwent the operation successfully. The technical success rate was 10/11. Bailout stenting was performed in one lesion because of flow-limiting dissection. Four lesions were grade 3 to 4 in peripheral artery calcium score system, and 9 lesions with calcification arc≥180°. Larger diameter drug-coated balloons were selected in 5 lesions after measurement of intravascular ultrasound. The follow-up time was (6.0±1.9) months (range: 3 to 9 months). The ankle-brachial index of the patient was significantly improved immediately after surgery (0.97±0.13 vs. 0.48±0.18, t=-7.60, P<0.01) and at 3 months after surgery (0.95±0.12 vs. 0.48±0.18, t=-7.17, P<0.01). The 3-month primary patency rate was 11/11, the target lesion reintervention was 0 and ulcer healing rate was 3/4. Conclusion: IVUS assisted ELA in the treatment of lower limb artery lesions is safe and effective in early stage.

Better timing for HoLEP: a retrospective analysis of patients treated with HoLEP over a 10-year period with a 1-year follow-up / 亚洲男科学杂志(英文版)

The aim of this study was to explore the optimal timing of holmium laser enucleation of the prostate (HoLEP) in patients presenting benign prostatic hyperplasia (BPH) with lower urinary tract symptoms (LUTS). A retrospective analysis was conducted based on the perioperative and postoperative outcome data of 1212 patients who underwent HoLEP in Shanghai Ninth People's Hospital (Shanghai, China) between January 2009 and December 2018. According to the preoperative International Prostate Symptom Score (IPSS), all patients whom we analyzed were divided into Group A (IPSS of 8-18) and Group B (IPSS of 19-35). Peri- and postoperative outcome data were obtained during the 1-year follow-up. IPSS changes were the main postoperative outcomes. The postoperative IPSS, quality of life, peak urinary flow rate, postvoid residual, and overactive bladder symptom score (OABSS) improved significantly. The IPSS improved further in the group with severe LUTS symptoms, but the postoperative IPSS was still higher than that in the moderate LUTS group. OABSSs showing moderate and severe cases after follow-up were more frequent in Group B (9.1%) than in Group A (5.2%) (P < 0.05). There were no significant intergroup differences in the intraoperative American Society of Anesthesiologists or hospitalization expense scores, and the medication costs, as well as the total costs, were significantly higher in Group B. In this retrospective study, HoLEP was an effective treatment for symptomatic BPH. For patients with LUTS, earlier surgery in patients with moderate severity may result in a marginally better 12-month IPSS than that in men with severe symptoms.

Mucosite oral em pacientes com câncer de cabeça e pescoço: limitações das escalas de graduação, avaliação da terapia fotodinâmica antimicrobiana no tratamento e associação com microbioma oral / Oral mucositis in patients with head and neck cancer: limitations of grading scales, evaluation of antimicrobial photodynamic therapy in treatment and association with oral microbiome

O câncer de cabeça e pescoço (CCP) é uma das principais causas de morbidade e mortalidade em todo mundo. Cirurgia, radioterapia (RT) e quimioterapia (QT) são os principais tratamentos empregados. Contudo, pacientes submetidos a RT e QT podem apresentar complicações como mucosite oral (MO). A terapêutica mais recomendada para MO é a fotobiomodulação (FTBM). Há diversas escalas para graduação da MO, entretanto elas apresentam limitações quando aplicadas em pacientes com CCP. Por esse motivo, foi desenvolvido uma revisão da literatura para descrever as escalas mais utilizadas e apontar as limitações. Microrganismos podem agravar a cicatrização da MO. Diante disso, a terapia fotodinâmica antimicrobiana (aPDT), poderia complementar a ação da FTBM. Assim, foi realizado estudo comparativo entre o uso da FTBM isolada e FTBM + aPDT no tratamento da MO. Mudanças no microbioma oral induzidas pela RT e seu papel no agravamento das complicações, como MO, vem sendo descrito. Em razão disso, amostras da cavidade oral dos pacientes com CCP foram coletadas com swab antes da RT (T0), entre 12 e 16 Grays (Gy) (T1), entre 30 e 36 Gy (T2) e acima de 60 Gy (T3) para caracterização molecular por meio da amplificação e sequenciamento das regiões v1-v2 do gene 16S rRNA. As escalas da World Health Organization - WHO, Radiation Therapy Oncology Group - RTOG e National Cancer Institute ­ NCI foram as mais utilizadas e todas apresentaram limitações associadas principalmente com a dificuldade de diferenciar entre os sinais e sintomas da MO e os do tumor, como por exemplo a disfagia. O estudo comparativo (FTBM isolada X FTBM + aPDT) foi composto por 14 pacientes, com câncer de boca e orofaringe submetidos a RT e QT concomitantes, com 6 pacientes no grupo FTBM isolada e 8 no grupo FTBM + aPDT. A média de redução no tamanho da MO no grupo intervenção foi de 0,70 cm2 (±0,35) e 0,30 cm2 (±1,10) no grupo controle. A média de duração foi de 18,37 dias (±12,12) para o grupo intervenção e 23 dias (±14,78) para o grupo controle. O grupo intervenção teve redução média de 3,40 pontos na escala de dor (±2,44), enquanto o grupo controle teve 0,17 (±2,28). O estudo prospectivo que avaliou o microbioma oral (filo e gênero) ao longo da RT foi composto por 49 pacientes com CCP. Intrigantemente não foi observado diferença no microbioma oral dos pacientes que apresentaram MO (n=31) daqueles que não apresentaram (n=18). Interessantemente foi observado ao final da RT (T3) diminuição de Porphyromonas (p=<0.0001), Prevotella (p=0.010), Fusobacterium (p=<0.0001), gêneros associados ao câncer. Não há uma escala ideal para a avaliação da mucosite oral em pacientes com CCP. A mensuração das lesões de MO associada aos dados de dor e duração da MO pode ser uma forma mais eficaz de avaliação. A combinação de FTBM + aPDT parece ser uma abordagem promissora para descontaminar lesões de MO. Não foi observado diferença no microbioma oral de pacientes com e sem MO. Mudanças na composição do microbioma oral foram observadas durante a RT.

Head and neck cancer (HNC) is one of the main causes of morbidity and mortality worldwide. Surgery, radiotherapy (RT) and chemotherapy (CT) are the main treatments used. However, patients undergoing RT and CT may present complications such as oral mucositis (OM). The most recommended therapy for OM is photobiomodulation (PBM-T). There are several scales for grading OM, however they have limitations when applied to patients with HNC. For this reason, a literature review was developed to describe the most used scales and point out the limitations. Microorganisms can aggravate OM healing. Therefore, antimicrobial photodynamic therapy (aPDT) could complement the action of PBM-T. Thus, a comparative study was carried out between the use of PBM-T alone and PBM-T + aPDT in the treatment of OM. RT-induced changes in the oral microbiome and its role in worsening complications such as OM have been described. For this reason, samples from the oral cavity of patients with HNC were collected with a swab before RT (T0), between 12 and 16 Grays (Gy) (T1), between 30 and 36 Gy (T2) and above 60 Gy (T3) for molecular characterization through amplification and sequencing of regions v1-v2 of the 16S rRNA gene. The World Health Organization - WHO, Radiation Therapy Oncology Group - RTOG and National Cancer Institute - NCI scales were the most used and all had limitations mainly associated with the difficulty of differentiating between the signs and symptoms of OM and those of the tumor, such as example dysphagia. The comparative study (isolated PBM-T X PBM-T + aPDT) consisted of 14 patients with oral and oropharyngeal cancer who underwent concomitant RT and CT, with 6 patients in the isolated PBM-T group and 8 in the PBM-T + aPDT group. The mean reduction in OM size in the intervention group was 0.70 cm2 (±0.35) and 0.30 cm2 (±1.10) in the control group. The mean duration was 18.37 days (±12.12) for the intervention group and 23 days (±14.78) for the control group. The intervention group had an average reduction of 3.40 points on the pain scale (±2.44), while the control group had 0.17 (±2.28). The prospective study that evaluated the oral microbiome (phylum and genus) during RT consisted of 49 patients with HNC. Intriguingly, no difference was observed in the oral microbiome of patients who had OM (n=31) and those who did not (n=18). Interestingly, a decrease in Porphyromonas (p=<0.0001), Prevotella (p=0.010), Fusobacterium (p=<0.0001) was observed at the end of RT (T3), genera associated with cancer. There is no ideal scale for assessing oral mucositis in patients with HNC. Measurement of OM lesions associated with data on pain and duration of OM may be a more effective form of evaluation. The combination of PBM- T + aPDT appears to be a promising approach to decontaminate OM lesions. No difference was observed in the oral microbiome of patients with and without OM. Changes in oral microbiome composition were observed during RT.

Comparative Evaluation of Clinical Efficacy of Diode LASER and Cryosurgery for Gingival Pigmentation: A Split-Mouth Randomized Clinical Study

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.
