Phototherapeutic keratectomy: current approaches and changing trends in a tertiary eye clinic / Ceratectomia fototerapêutica: abordagens atuais e tendências de mudança em uma clínica oftalmológica terciária

ABSTRACT Purpose: To examine the efficacy of phototherapeutic keratectomy as a treatment for variable pathologies with anterior corneal opacities and evaluate the distribution of phototherapeutic keratectomy indications over the past 10 years. Methods: The records of 334 eyes from 276 patients who underwent phototherapeutic keratectomy between March 2010 and 2020 were retrospectively reviewed. Etiologies of the patients who underwent phototherapeutic keratectomy were noted, and their changes were examined. Refractive and visual acuity results before and after the operation were recorded and analyzed according to etiology. Results: The mean age of the patients was 40.7 ± 16.2 years (range: 19-84). The mean follow-up was 25.5 ± 19.1 months (range: 3-96). Phototherapeutic keratectomy was most frequently applied for corneal stromal dystrophies (44%, 151 eyes from 111 patients), and granular dystrophy was the most common phototherapeutic keratectomy indication among corneal dystrophies. Unlike other indications, there has been an increase in the application of phototherapeutic keratectomy for persistent subepithelial opacities due to adenoviral conjunctivitis in the past 10 years. There was a significant increase in visual acuity in all groups except for the recurrent epithelial defect group (p<0.05). The greatest improvement in visual acuity was detected for stromal dystrophies in the granular dystrophy subgroup. Conclusion: Despite changing indication trends, phototherapeutic keratectomy remains an effective and reliable treatment for anterior corneal lesions.

RESUMO Objetivo: Examinar a eficácia da ceratectomia fo­toterapêutica para o tratamento de patologias variáveis que apresentarem opacidades anteriores da córnea, e avaliar a distribuição das indicações de ceratectomia fototerapêutica nos últimos 10 anos. Métodos: Foram revisados retrospectivamente os prontuários de 276 pacientes, com 334 olhos tratados com ceratectomia fototerapêutica entre março de 2010 e o ano de 2020. As etiologias dos pacientes submetidos à ceratectomia fototerapêutica foram anotadas e suas alterações foram examinadas. Os resultados refrativos e de acuidade visual antes e após a operação foram registrados e analisados de acordo com a etiologia. Resultados: A idade média dos pacientes foi de 40,7 ± 16,2 anos (faixa: 19-84). O tempo médio de acompanhamento foi de 25,5 ± 19,1 meses (faixa: 3-96). A ceratectomia fototerapêutica foi aplicada com mais frequência para distrofias estromais corneanas (44%, 151 olhos de 111 pacientes); entre as distrofias corneanas como um todo, a distrofia granular foi a indicação terapêutica mais comum desse procedimento. Ao contrário de outras indicações, nos últimos 10 anos houve um aumento na aplicação de ceratectomia fototerapêutica em casos de opacidade subepitelial persistente causada por conjuntivite adenoviral. Houve um aumento significativo na acuidade visual em todos os grupos, exceto para o grupo com defeito epitelial recorrente (p<0,05). A maior melhora na acuidade visual foi detectada em casos de distrofia estromal, no subgrupo das distrofias granulares. Conclusão: Apesar das mudanças nas tendências de indicação, a ceratectomia fototerapêutica continua sendo uma abordagem terapêutica eficaz e confiável para tratar lesões da córnea anterior.

Impact of Saccharomyces boulardii on jaundice in premature infants undergoing phototherapy

Abstract Objectives To evaluate the therapeutic effect of Saccharomyces boulardii supplementation on jaundice in premature infants undergoing phototherapy. Methods In this article, the authors reviewed 100 hospitalized jaundiced premature infants under 35 weeks of gestational age. All infants were assigned to a control group (n= 45) and a treatment group (n= 55) randomly. The infants in the treatment group received S. boulardii supplementation by undergoing phototherapy and the infants in the control group were only treated by phototherapy. The total serum bilirubin levels were detected before and at the end of phototherapy, and transcutaneous bilirubin levels were measured on the 1st, 4th, 8th and 15th day of treatment. The duration of jaundice resolution and phototherapy, stool frequency, and characteristics were compared after phototherapy. Results The duration of jaundice resolution and phototherapy were shortened. Total serum bilirubin level was lower than the control group at the end of phototherapy (p < 0.05). Transcutaneous bilirubin levels decreased more significantly on the 8th and 15th day of treatment (p < 0.05), while there were no significant differences on the post-treatment 1st and 4th day (p > 0.05). In addition, bowel movements including stool frequency and Bristol Stool Form Scale ratings of stools also improved after treatment. Conclusions S. boulardii in combination with phototherapy is effective and safe in reducing bilirubin levels and duration of phototherapy, accelerating jaundice resolution in premature infants with jaundice. The procedure also provided an ideal therapeutic effect of diarrhea induced by phototherapy to promote compliance and maternal-infant bonding.

Evaluation of the comparative effects of infrared and red laser photobiomodulation therapy on skeletal muscle atrophy in an immobilization model in rats

Introduction: Skeletal muscle atrophy leads to a reduction in muscle strength, functionality, and the quality of life of individuals. Objective: To explore the effects of two different wavelengths (red and infrared) of laser PBMT on muscle atrophy and its active ingredients on skeletal muscle atrophy using an in vivo model of muscle atrophy. Methods: Thirty-two Wistar rats were randomly divided into four experimental groups: control (CG) animals were not immobilized and did not receive any type of treatment; immobilized animals with no treatment (ImC); immobilized animals submitted to red laser with wavelength of 660 nm (ImR) and near-infrared laser with wavelength of 808 nm (ImIR) treatments. The treatments were applied daily, at 2 points in the right gastrocnemius muscle (cranial and caudal), through the punctual contact technique, for 9 sessions, with the first application immediately after removing the cast. Results: The histological results demonstrated that in both treated groups (red and infrared wavelengths) a reduction of the inflammatory infiltrate and less connective tissue thickening when compared to the ImC. However, only infrared light was observed regenerating muscle fibers and an increase in the number of oxidative fibers (type I). Conclusion: These results suggest that red and infrared wavelength laser PBMT were able to promote changes in the morphology of the gastrocnemius muscle submitted to atrophy in an experimental immobilization model, reducing the inflammatory infiltrate and the formation of intramuscular connective tissue. However, infrared laser PBMT promoted more evident positive effects by increasing regenerating muscle fibers and the number of oxidative fibers.

Use of prophylactic phototherapy for RhD neonatal disease in a referral service

Abstract Objective: This study aimed to describe the effect of prophylactic phototherapy in the treatment of infants with Neonatal Hemolytic Disease. Method: A retrospective cohort study was carried out with 199 RhD-positive infants, born to RhD-negative mothers, alloimmunized for RhD antigen, between January 2009 and December 2018. Results: The incidence of exchange transfusions in the study population was 9.5%, with a mean maximum bilirubin value of 11.3 mg % (± 4.3mg %). Bilirubin's maximum peak was achieved with a mean of 119.2 life hours (± 70.6h). Conclusions: The low incidence of exchange transfusion, the extended maximum bilirubin peak for later ages, and the low mean of the maximum bilirubin values may indicate a positive effect of prophylactic phototherapy in the treatment of this disease. Further studies must be carried out to confirm these findings.

Research advances in the treatment of Crigler-Najjar syndrome / 临床肝胆病杂志

Crigler-Najjar syndrome (CNS) is an autosomal recessive disorder in which the content of plasma unconjugated bilirubin is increased due to the reduction or complete deficiency of the activity of bilirubin uridine diphosphate glucuronosyl transferase 1A1 (UGT1A1), classified as CNS type Ⅰ and Ⅱ. CNS type Ⅰ is the most severe, which will develop into kernicterus, damage the brain nervous system, and even threaten the life of patients. This article introduces six CNS treatment techniques, including phototherapy, plasma exchange, drug therapy, liver transplantation, hepatocyte transplantation and gene therapy. The applicable patient types, treatment effects and existing deficiencies of each technique were summarized. Phototherapy, plasma exchange, drug therapy and hepatocyte transplantation can temporarily control serum levels and reduce the risk of jaundice, but cannot completely restore UGT1A1 enzyme activity; liver transplantation is currently the only treatment option for CNS type Ⅰ patients, but is limited by suitable liver donors and post-operative immune rejection. Gene therapy has the most promising application in the treatment of genetic disorders such as CNS, which can provide more viable therapeutic techniques for CNS patients.

Real-time SERS monitoring anticancer drug release along with SERS/MR imaging for pH-sensitive chemo-phototherapy

In situ and real-time monitoring of responsive drug release is critical for the assessment of pharmacodynamics in chemotherapy. In this study, a novel pH-responsive nanosystem is proposed for real-time monitoring of drug release and chemo-phototherapy by surface-enhanced Raman spectroscopy (SERS). The Fe3O4@Au@Ag nanoparticles (NPs) deposited graphene oxide (GO) nanocomposites with a high SERS activity and stability are synthesized and labeled with a Raman reporter 4-mercaptophenylboronic acid (4-MPBA) to form SERS probes (GO-Fe3O4@Au@Ag-MPBA). Furthermore, doxorubicin (DOX) is attached to SERS probes through a pH-responsive linker boronic ester (GO-Fe3O4@Au@Ag-MPBA-DOX), accompanying the 4-MPBA signal change in SERS. After the entry into tumor, the breakage of boronic ester in the acidic environment gives rise to the release of DOX and the recovery of 4-MPBA SERS signal. Thus, the DOX dynamic release can be monitored by the real-time changes of 4-MPBA SERS spectra. Additionally, the strong T2 magnetic resonance (MR) signal and NIR photothermal transduction efficiency of the nanocomposites make it available for MR imaging and photothermal therapy (PTT). Altogether, this GO-Fe3O4@Au@Ag-MPBA-DOX can simultaneously fulfill the synergistic combination of cancer cell targeting, pH-sensitive drug release, SERS-traceable detection and MR imaging, endowing it great potential for SERS/MR imaging-guided efficient chemo-phototherapy on cancer treatment.

Research progress of nano delivery system in breast cancer treatment / 中国药房

Breast cancer is a malignant tumor that seriously threatens women’s health at present. Although surgical treatment is the most direct and effective， it is limited by many factors and needs to be assisted by other treatments. In addition to conventional radiotherapy， these adjuvant therapies also include chemotherapy， gene therapy， phototherapy and so on. However， the therapeutic agents used in these treatment methods have some limitations， such as poor water-solubility， instability and targeting. With the development of nano-technology， more and more researchers construct and study nano delivery system for breast tumor treatment， such as response system designed based on tumor microenvironment， temperature sensitive response system， nano delivery system based on specific proteins of tumor cell membrane， etc. The author summarizes the nano delivery system， and finds that these nano delivery systems can not only improve the water-solubility and stability of the therapeutic agents， but also accurately deliver them to the breast tumor site by targeted means， improve the efficacy and reduce toxic side effects， which provides new ideas for the treatment of breast cancer in the future.

Simulation of non-invasive phototherapy therapy mediated by medical LED array light source / 国际生物医学工程杂志

Objective:To simulate the spot characteristics of light emitting diode (LED) array light sources used in non-invasive phototherapy at different distances and to provide reference for the formulation of clinical non-invasive phototherapy treatment schemes.Methods:The ray tracing module in Comsol software was used to simulate the spot characteristics of LED light sources with different power and arrays at different distances, and the fitting curve was analyzed. The model was verified by the actual LED spot measurement, and the feasibility of the treatment scheme was verified by the mouse back wound model.Results:Under the irradiation of 2×2 LED light source array, with the increase of the vertical distance from the light source, the area of the effective area and the treatment area gradually increased, the power density value in the area gradually decreased, and the uniformity gradually increased. These changes showed a linear or binomial correlation with the vertical distance. The model was improved based on the actual LED light spot, and the new model consisted of an array of 18 LEDs as the light source, and the treatment area showed better uniformity and power density values. The simulated optical parameters were used to treat mice’s wounds with light, and the results showed that light treatment could promote wound healing.Conclusions:The established medical LED array light source spot characteristics simulation can provide a reference for the development of clinical non-invasive phototherapy protocols, thus helping the clinic select the appropriate LED power and array distribution according to the treatment needs and also providing a basis for the development of medical LED array light sources.

Bullous lesions following phototherapy in a newborn

ABSTRACT A male infant presented with progressive jaundice immediately after birth. Fecal acholia and choluria associated with extensive bullous skin lesions in his trunk, abdomen, and upper and lower limbs developed during phototherapy. Several diagnostic hypotheses were presented, including neonatal porphyria, hemochromatosis, Alagille syndrome, and neonatal lupus. A 24-hour urine sample for the dosage of urinary porphyrins was collected, showing high results (1823.6µg in 100mL). At 50 days of life, fluorescence spectroscopy using a Wood's lamp revealed simultaneous bright red fluorescence of urine-stained diapers and sample blood. A definitive diagnosis of congenital erythropoietic porphyria was made following identification of a mutation of the uroporphyrinogen synthetases III gene on genetic testing. The patient was subsequently maintained in a low light environment since then, resulting in improvement of the lesions. Congenital erythropoietic porphyria is a disease of the group of porphyrias that presents shortly after birth with blistering occurring in regions exposed to the sun or other ultraviolet light. Atrophic scars, mutilated fingers, and bright red fluorescence of the urine and teeth may also be observed. There is no specific treatment, and prophylaxis comprising a total avoidance of sunlight is generally recommended. A high degree of suspicion is required for diagnosis. An early diagnosis can lead to less damage. Here, we present the case of a newborn with congenital erythropoietic porphyria diagnosed after presenting with bullous lesions secondary to phototherapy.

A Comparative Study of Phototherapy Versus Phototherapy Plus Ursodeoxycholic Acid in the Treatment of Indirect Hyperbilirubinemia in Neonate

Background: Hyperbilirubinemia is a common neonatal problem. Phototherapy and exchange transfusion is the conventional treatment for indirect hyperbilirubinemia. In the treatment of cholestatic liver disorders, Ursodeoxycholic acid (UDCA) is a bile acid widely used. Few studies have been conducted using UDCA in indirect hyperbilirubinemia. Aim of the study: This study was planned to assess the additive effect of UDCA on reducing indirect hyperbilirubinemia in neonates receiving phototherapy. Material & Methods:This prospective randomized controlled trial was conducted among neonates with indirect hyperbilirubinemia in the neonatal wards of Bangladesh Shishu Hospital and Institute, Dhaka, Bangladesh from June 2018 to July 2020. Finally, 140 neonates were included in the study. Eligible cases were randomized into two groups by the lottery method. Group A (n=70) received phototherapy and Group B (n=70) received UDCA at a dose of 10 mg/kg/day orally twice daily in addition to phototherapy. Total serum bilirubin levels were measured every 12 hours until serumbilirubinlevel falls below 10 mg/dl and then phototherapy was stopped. Demographic data, clinical features, laboratory parameters, outcome variables, and complications were recorded in a pre-format sheet. CBC with PBF, Total and indirect bilirubin, Blood grouping and Rh and typing, CRP, Reticulocyte count, and Coombs test were obtained at enrolment. Comparison of parameters among themselves was done by unpaired t-test and chi-square test. Analyzed outcomes were: time for resolution of jaundice, total duration of phototherapy, length of hospital stays, and adverse effects of the drug. The two groups did not differ statistically in age, sex or weight. The mean total serum bilirubin level measured at 12, 24, 36, 48, and 60 hours of treatment in group A was 16.10±1.43, 14.76±1.45, 13.34±1.68, 11.84±1.35, and, 10.57±0.74 respectively, and in the group, B was,15.18±1.63, 13.18±2.25, 11.39±1.56, 9.84±0.81 and, 9.44±0.46 respectively (p<0.001). The mean duration of phototherapy (64.11±10.8 vs. 47.18±7.51 hours, p<0.001) and length of hospital stay (2.80 ±0.40 vs. 2.19±0.39 days, p=<0.001).Conclusion:The inclusion of UDCA as an adjuvant to phototherapy is more effective in reducing indirect hyperbilirubinemia in neonates.

Resumen El imatinib es un agente antineoplásico que actúa como inhibidor de la tirosina-cinasa. Los efectos adversos cutáneos son, en general, leves y autolimitados. Dentro de estos, la erupción liquenoide es infrecuente y suele mejorar sólo con tratamiento tópico. Presentamos el caso de una paciente con erupción liquenoide por imatinib refractaria al tratamiento con corticoides tópicos, con respuesta favorable a terapia de luz ultravioleta B de banda estrecha. No existen casos publicados a la fecha en la literatura de erupción liquenoide por imatinib tratada con fototerapia.

Abstract Imatinib is an antineoplastic agent that acts as a tyrosine kinase inhibitor. Cutaneous adverse effects are generally mild and self-limited. The lichenoid eruption due to imatinib is rare. It usually improves just with topical treatment. We present the case of a patient with a lichenoid reaction due to imatinib, refractory to treatment with topical corticosteroids, with a favorable response to narrow-band ultraviolet B phototherapy. There are no published cases to date in the literature of lichenoid eruption due to imatinib treated with phototherapy.

Uso da fotobiomodulação laser no tratamento de úlceras venosas: uma revisão sistemática / Laser photobiomodulation in the treatment of venous ulcers: a systematic review

O objetivo do presente trabalho foi relatar a eficácia da fotobiomodulação laser na abordagem de úlceras venosas de membros inferiores e como se dá o papel da enfermagem nesse contexto. Tratou-se de uma revisão sistemática que utilizou as bases de dados eletrônicas PubMed, BVS, SCIELO e Lilacs, além da busca no repositório de teses e dissertações pelo cruzamento dos descritores livres e provenientes do DeCS através dos operadores booleanos AND e OR: "laserterapia", "fotobiomodulação laser" e "úlceras venosas". Os critérios de inclusão estabelecidos foram estudos prospectivos, teses e dissertações escritas nos idiomas inglês, português e espanhol, e publicações entre o período de 2010-2020. A revisão foi conduzida conforme metodologia PRISMA, utilizou-se os critérios de Jadad para avaliação da qualidade dos manuscritos. Dos 104 artigos encontrados, apenas 8 contemplavam os critérios de inclusão, tendo uma população total de 942 pacientes. Notou-se que a maioria dos estudos mostrou a eficácia do uso da laserterapia, principalmente quando associado ao uso da terapêutica comum, como a terapia compressiva, agentes tópicos e farmacoterapia. A fotobiomodulação laser demonstrou ser eficaz, porém ainda são necessários mais estudos com o objetivo de uniformizar os parâmetros de aplicação dessa modalidade terapêutica.

The objective of this work was to investigate the effectiveness of laser photo-biomodulation in lower limb venous ulcers and the role of nursing in this context. This is a systematic review, using the PubMed, BVS, SCIELO and Lilacs electronic databases in addition to searching the repository of thesis and dissertations by crossing the free descriptors coming from the DeCS through the Boolean operators AND and OR: "laser therapy", "laser photo-biomodulation" and "venous ulcers". The inclusion criteria were prospective studies, theses and dissertations written in English, Portuguese, or Spanish, and publications in the 2010-2020 period. From the 104 articles found, only 8 met the inclusion criteria, with a total population of 942 patients. It could be observed that most studies showed the effectiveness of using laser therapy, especially when associated with the use of common therapy, such as the compressive therapy, topical agents, and pharmacotherapy. The laser photo-biomodulation was also shown as being effective, but further studies are needed to standardize the application parameters for this therapeutic modality.
