AL aumentar un año de edad, disminuye en un 15 % la CVA, y al aumentar la depresión, la ansiedad y el comportamiento sedentario disminuye la CVA. Además, los niveles de depresión y ansiedad son mayores en mujeres, estudiantes mayores, sin apoyo de los padres y personas sedentarias. Conclusiones: La CVRS se asocia con estados de ánimo, actividad física, comportamiento sedentario y apoyo de los padres; mientras que los estados de ánimo se asocian con el sexo, el apoyo de los padres, la CVS y el sedentarismo.

Introduction: Even though health-related quality of life (HRQL) and mood states are key indicators of the well-being of adolescents, their relationship has not been analyzed in students from Antioquia, Colombia. Objective: To determine HRQL and mood states in schoolchildren from Antioquia. Materials and methods: A cross-sectional study was conducted on 1,957 schoolchildren and adolescents aged between 9 and 20 years. Measurements of HRQL, anxiety, depression, hostility and happiness, physical activity, sedentary behavior, parental social support, and socioeconomic status were applied. Results: A high quality of life (HQL) was observed more frequently in male participants, students with parental support, physically active, and those belonging to medium and high socioeconomic status. HQL decreased 15% as their age increased by one year. Also, HQL was reduced when depression, anxiety, and sedentary behavior increased. Furthermore, depression and anxiety levels were higher in women, older students, as well as in those without parental control and with sedentary behavior. Conclusions: HRQL is associated with mood states, physical activity, sedentary behavior, and parental support. In contrast, mood states are related to gender, parental support, HQL, and sedentary lifestyle.

Periodontal therapy for hopeless mandibular anterior teeth: a retrospective case report with a multidisciplinary approach and a 20-year follow-up

Introduction: This case report presents the intentional periodontal maintenance of two periodontal hopeless lower central incisors with a multidisciplinary approach and 20-year follow-up. Case presentation: A 36-year-old male, in 2001, was diagnosed with aggressive periodontitis, gingival swelling, bleeding, and mandibular central incisors with mobility and poor prognosis. Following periodontal therapy (phase I), root canal treatment, and occlusal adjustment, #31 and #41 were gently extracted to remove the granulation tissues, calculus, and infected cementum from the root surface. Then, tetracycline-HCl was applied for 5 minutes on the root surfaces. The teeth were repositioned into the sockets and splinted with a lingual bar. At 3 months, the bar was removed, and a free gingival autogenous graft was done to improve the local keratinized tissue width. Mobility scores, pocket depths, and clinical attachment levels were recorded, and radiographs were taken at 1, 5, and 20 years. The 5-year follow-up showed that the teeth were clinically and radiographically in function. There was a reduction in probing depth and a gain in clinical attachment and radiographic alveolar bone levels. After 20 years, #41 was stable, but #31 had external root resorption, leading to a new treatment plan (dental implants) and extraction. Conclusion: The clinical result of this case was satisfactory for 20 years. Intentional periodontal maintenance of the teeth may be an alternative treatment, even considering the high level of complexity.

Virtual planning as a resource for correcting severe facial asymmetry ­ case report / Planejamento virtual como recurso para correção de assimetria facial severa ­ relato de caso

A hiperplasia hemimandibular é responsável por prejuízos estéticos, funcionais, motores e psicossociais. Com etiologia incerta, ocorre frente ao desequilíbrio de fatores regulatórios de crescimento presentes na camada cartilaginosa do côndilo. O relato objetiva descrever a tomada de decisões baseada em exames complementares específicos aliados à adequada intervenção cirúrgica da lesão. Paciente gênero feminino, 33 anos de idade, compareceu à clínica particular com queixa principal de "face assimétrica", foi requerido uma avaliação cintilográfica objetivando e confirmando a interrupção do crescimento condilar, descartando a hipótese de Osteocondroma e condilectomia. Após preparo ortodôntico prévio, os exames tomográficos foram utilizados na criação de um protótipo que foi impresso após a realização dos movimentos ósseos planejados. Mediante à reconstrução, foi concluído que a assimetria presente não seria totalmente corrigida somente através da intervenção ortognática, sendo necessária também uma osteotomia removendo parte da base do corpo e ângulo mandibular, através da confecção de um guia de corte, promovendo à reanatomização sem a necessidade de acesso extra oral submandibular, evitando uma cicatriz em face feminina. Paciente encontra-se em pós-operatório de 60 meses, sem queixas e satisfeita. Portanto, é evidenciado cada vez mais a influência positiva que o planejamento virtual pode trazer aos profissionais na otimização dos resultados cirúrgicos.

Hemimandibular hyperplasia is responsible for aesthetic, functional, motor, and psychosocial impairments. With an uncertain etiology, it occurs due to the imbalance of regulatory growth factors present in the cartilaginous layer of the condyle. The report aims to describe decision-making based on specific complementary exams combined with the appropriate surgical intervention for the condition. A 33-year-old female patient presented at a private clinic with the main complaint of "asymmetric face." A scintigraphic evaluation was requested to objectively confirm the interruption of condylar growth, ruling out the hypothesis of Osteochondroma and condylectomy. After prior orthodontic preparation, tomographic exams were used to create a prototype that was printed after planned bone movements. Through the reconstruction, it was concluded that the existing asymmetry would not be entirely corrected through orthognathic intervention alone, necessitating also an osteotomy to remove part of the base of the body and mandibular angle. This was done through the creation of a cutting guide, allowing for reanatomization without the need for submandibular extraoral access, thus avoiding a scar on the female face. The patient is 60 months postoperative, with no complaints and satisfied. Therefore, the increasingly positive influence of virtual planning on optimizing surgical outcomes for professionals is evident.

Percepção profissional sobre tratamento endodôntico em sessão única e múltiplas sessões / Professional perception of single and multi-session endodontic treatment

Na odontologia a decisão do tratamento é exclusiva dos cirurgiões dentistas e suas percepções, incluindo filosofia de tratamento, fazendo com que a prática de novos conceitos, tratamentos ou técnicas dependam não apenas de sua lógica ou eficácia biológica. Sendo assim, este estudo teve como objetivo avaliar os parâmetros envolvidos na tomada de decisão de cirurgiões dentistas clínicos e especialistas para a realização do tratamento endodôntico em sessão única ou múltiplas sessões. Para tanto, este estudo contou com uma coleta de dados através de um questionário online, aplicado cirurgiões dentistas clínicos gerais e especialistas em endodontia. As respostas foram tabuladas e analisadas por meio de estatística descritiva. Os resultados revelaram que a maioria dos endodontistas e dos clínicos gerais prefere realizar tratamento endodôntico em sessão única, devido ao menor desperdício de material, além do melhor domínio da anatomia e tratamento em um único momento. O motivo mais comum para os endodontistas e clínicos gerais escolherem o tratamento com múltiplas visitas é para dentes com prognóstico duvidoso e os casos em que o profissional aguarda a remissão dos sintomas antes da obturação. Em conclusão, a maioria dos endodontistas e dos clínicos gerais preferiu realizar tratamento endodôntico em sessão única.

In dentistry, treatment decisions are made exclusively by dental surgeons and their perceptions, including treatment philosophy, which means that the practice of new concepts, treatments or techniques depends not only on their logic or biological efficacy. Therefore, the aim of this study was to evaluate the parameters involved in clinical and specialist dental surgeons' decision to carry out endodontic treatment in single or multiple sessions. To this end, data was collected using an online questionnaire administered to general dental surgeons and endodontic specialists. The answers were tabulated and analyzed using descriptive statistics. The results revealed that the majority of endodontists and general practitioners prefer to carry out endodontic treatment in a single session, due to less wastage of material, as well as better mastery of the anatomy and treatment at a single time. The most common reason for endodontists and general practitioners to choose treatment with multiple visits is for teeth with a doubtful prognosis and cases in which the professional is waiting for symptoms to remit before filling. In conclusion, the majority of endodontists and general practitioners preferred to carry out endodontic treatment in a single session.

Práticas integrativas e complementares de saúde em Sergipe / Integrative and complementary health practices in Sergipe

A atenção primária em saúde (APS) é o primeiro nível de atenção em saúde, sendo um elo entre a população e o setor de saúde. Tem-se buscado a humanização dos atendimentos, e essa mudança, refletida pelas mudanças da sociedade, trouxe a implementação da Política Nacional de Práticas Integrativas e Complementares (PNPIC) no SUS. O objetivo deste trabalho foi realizar uma análise da tendência da quantidade das práticas integrativas e complementares realizadas nas regionais de saúde de Sergipe de 2017 a 2023, associando com a cobertura da atenção primária. Foi realizada análise de dados secundários através do Departamento de Informática do Sistema Único de Saúde (DATASUS), como forma de organização no período de junho/2015 a junho/2023 por regional de saúde de Sergipe. As análises dos dados foram descritivas e de correlação e por meio de análise de série temporal. A regional de saúde de Lagarto foi a que mais executou as práticas integrativas e complementares no período analisado e algumas regionais não tiveram continuidade na realização destas práticas. A regional de saúde com maior cobertura de APS foi Itabaiana. Não foi possível observar associação entre o número de práticas e a cobertura de atenção primária. Com o intuito de que o atendimento aos indivíduos seja cada vez mais humanizado, e em virtude da realização das práticas integrativas ter baixo índice ou descontinuidade em algumas regiões de Saúde de Sergipe, é relevante que os profissionais de saúde busquem conhecimentos sobre essas práticas, como também, os gestores em saúde incentivem esta ação.

Primary health care (PHC) is the first level of health care, being a link between the population and the health sector. The aim has been to humanize care, and this change, reflected by changes in society, has led to the implementation of the National Policy on Integrative and Complementary Practices (PNPIC) in the SUS. The objective of this work was to carry out an analysis of the trend in the number of integrative and complementary practices carried out in the health regions of Sergipe from 2017 to 2023, associating it with primary care coverage. Secondary data analysis was carried out through the Department of Informatics of the Unified Health System (DATASUS), as a form of organization from June/2015 to June/2023 by health region in Sergipe. Data analyzes were descriptive and correlational and through time series analysis. The Lagarto health region was the one that carried out the most integrative and complementary practices in the period analyzed and some regions did not continue to carry out these practices. The health region with the highest PHC coverage was Itabaiana. Observing an association between the number of practices and primary care coverage was impossible. With the aim that care for individuals is increasingly humanized, and because the implementation of integrative practices has a low rate or discontinuity in some Health regions of Sergipe, health professionals must seek knowledge about these practices as well as health managers encourage this action.

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.

Hyperbaric Medicine in Pediatrics — reality of a Portuguese reference center / Medicina Hiperbárica em Pediatria — realidade de um centro de referência português

ABSTRACT Objective: To identify and characterize the population of Pediatric patients referred to our hyperbaric oxygen therapy center. Methods: Retrospective and observational study, including pediatric patients treated with hyperbaric oxygen therapy, from 2006 to 2021, at the hyperbaric medicine reference center in the north of Portugal. Variables of interest were extracted from electronic medical records. Results: Our study included 134 patients. The most frequent reasons for referral were carbon monoxide poisoning (n=59) and sudden sensorineural hearing loss (n=41). In 75 cases (56%), treatment was initiated in an urgent context. Symptom presentation at Emergency Department varied among patients, the most frequent being headache and nausea/vomiting. Concerning carbon monoxide poisoning, the most common sources were water heater, fireplace/brazier, and boiler. Regarding adverse effects, it was identified one case of intoxication by oxygen and four cases of middle ear barotrauma. Conclusions: The most frequent cause for referral was carbon monoxide poisoning. All patients evolved favorably, with few side effects being reported, emphasizing the safety of this therapy. While most pediatricians may not be aware of the potential benefits arising with hyperbaric oxygen therapy, it is of upmost importance to promote them, so that this technique is increasingly implemented.

RESUMO Objetivo: Identificar e caracterizar a população de casos pediátricos encaminhados para o nosso centro de oxigenoterapia hiperbárica. Métodos: Estudo retrospetivo e observacional, que incluiu doentes pediátricos tratados com oxigenoterapia hiperbárica, de 2006 a 2021, no centro de referência de medicina hiperbárica do norte de Portugal. As variáveis de interesse foram extraídas dos processos clínicos eletrônicos. Resultados: O nosso estudo incluiu 134 casos. Os motivos de encaminhamento mais frequentes foram intoxicação por monóxido de carbono (n=59) e surdez súbita neurossensorial (n=41). Em 75 casos (56%) o tratamento foi iniciado em contexto de urgência. Os sintomas de apresentação à admissão variaram entre os diferentes casos, sendo os mais frequentes cefaleias e náuseas/vômitos. No que diz respeito à intoxicação por monóxido de carbono, as fontes mais comuns foram o aquecedor, lareira/braseiro e caldeira. Com relação aos efeitos adversos, foram identificados um caso de intoxicação por oxigênio e quatro casos de barotrauma do ouvido médio. Conclusões: A causa mais frequente de encaminhamento foi a intoxicação por monóxido de carbono. Todos os pacientes evoluíram favoravelmente e foram registrados poucos efeitos adversos, o que enfatiza a segurança desta terapia. Uma vez que a maioria dos pediatras pode não estar informada sobre os potenciais benefícios da oxigenoterapia hiperbárica, é de extrema importância promovê-los para que esta técnica seja cada vez mais implementada.

Seasonality of the incidence of bronchiolitis in infants — Brazil, 2016-2022: An interrupted time-series analysis / Sazonalidade da incidência de bronquiolite em lactentes — Brasil, 2016-2022: Uma análise de série temporal interrompida

ABSTRACT Objective: To evaluate the seasonality of acute bronchiolitis in Brazil during the 2020-2022 season and compare it with the previous seasons. Methods: Data from the incidence of hospitalizations due to acute bronchiolitis in infants <1 year of age were obtained from the Department of Informatics of the Brazilian Public Health database for the period between 2016 and 2022. These data were also analyzed by macro-regions of Brazil (North, Northeast, Southeast, South, and Midwest). To describe seasonal and trend characteristics over time, we used the Seasonal Autoregressive Integrated Moving Averages Model. Results: Compared to the pre-COVID-19 period, the incidence of hospitalizations related to acute bronchiolitis decreased by 97% during non-pharmacological interventions (March 2020 - August 2021) but increased by 95% after non-pharmacological interventions relaxation (September 2021 - December 2022), resulting in a 16% overall increase. During the pre-COVID-19 period, hospitalizations for acute bronchiolitis followed a seasonal pattern, which was disrupted in 2020-2021 but recovered in 2022, with a peak occurring in May, approximately 4% higher than the pre-COVID-19 peak. Conclusions: This study underscores the significant influence of COVID-19 interventions on acute bronchiolitis hospitalizations in Brazil. The restoration of a seasonal pattern in 2022 highlights the interplay between public health measures and respiratory illness dynamics in young children.

RESUMO Objetivo: Avaliar a sazonalidade da bronquiolite aguda no Brasil durante a temporada 2020-2022 e compará-la com a das temporadas anteriores. Métodos: Os dados de incidência de internações por bronquiolite aguda em lactentes <1 ano de idade foram obtidos do Departamento de Informática da base de dados da Saúde Pública Brasileira para o período entre 2016 e 2022. Esses dados também foram analisados por macrorregiões do Brasil (Norte, Nordeste, Sudeste, Sul e Centro-Oeste). Para descrever características sazonais e de tendência ao longo do tempo, utilizamos o Modelo de Médias Móveis Integradas Autorregressivas Sazonais. Resultados: Em comparação com o período pré-COVID-19, a incidência de hospitalizações relacionadas com bronquiolite aguda diminuiu 97% durante as intervenções não farmacológicas (março de 2020 - agosto de 2021), mas aumentou 95% após a flexibilização das intervenções não farmacológicas (setembro de 2021 - dezembro de 2022), resultando no aumento geral de 16%. Durante o período pré-COVID-19, as hospitalizações por bronquiolite aguda seguiram um padrão sazonal, que foi interrompido em 2020-2021, mas recuperaram-se em 2022, com um pico ocorrido em maio, aproximadamente 4% superior ao pico pré-COVID-19. Conclusões: Este estudo ressalta a influência significativa das intervenções contra a COVID-19 nas hospitalizações por bronquiolite aguda no Brasil. A restauração de um padrão sazonal em 2022 sublinha a interação entre as medidas de saúde pública e a dinâmica das doenças respiratórias em crianças pequenas.

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.

Rare case of mantle cell lymphoma of the lacrimal sac

ABSTRACT Mantle cell lymphoma of the ocular and periorbital regions is extremely rare but should be considered in the differential diagnosis of lesions affecting the periorbital tissues. In this study, we present a rare case of mantle cell lymphoma of the lacrimal sac in a 65-year-old male presenting with a mass in the lacrimal sac region and epiphora. After clinical examinations and imaging studies, the mucocele was misdiagnosed. Considering the unexpected findings during external dacryocystorhinostomy, a frozen biopsy was performed, which confirmed the diagnosis of lymphoma.

Protein profile of purified plasma- and aqueous humor-derived extracellular vesicles from patients with ocular toxoplasmosis

ABSTRACT Purpose: To characterize the extracellular vesicle protein cargo in the aqueous humor and plasma of patients with ocular toxoplasmosis. Methods: Aqueous humor and plasma were collected from six patients with active ocular toxoplasmosis and six patients with cataract. Extracellular vesicles were isolated, and western blotting and mass spectrometry were performed for protein analysis. Results: All plasma samples from patients with ocular toxoplasmosis and cataract were positive for the tetraspanins CD63 and TSG101. However, the aqueous humor from patients with ocular toxoplasmosis was positive only for CD63. Sixty-seven new unreported proteins were identified in the aqueous humor and plasma of patients with the ocular toxoplasmosis and cataract. Of the 67 proteins, 10 and 7 were found only in the cataract and ocular toxoplasmosis groups, respectively. In general, these proteins were involved in immune system activation and retina homeostasis and were related to infections and retina-associated diseases. Conclusion: The distinct protein signatures between ocular toxoplasmosis and cataract may be helpful in the differential diagnosis of ocular toxoplasmosis. However, more studies are needed to better understand the role of these proteins in the pathogenesis of ocular toxoplasmosis.

Intraocular pressure modulation with thermal stimuli

ABSTRACT Purpose: This study aimed to determine whether early-stage intraocular pressure can be modulated using a thermal face mask. Methods: In this prospective clinical study, healthy participants were randomized on a 1:1:1 allocation ratio to three mask groups: hypothermic (G1), normothermic (G2), and hyperthermic (G3). After randomization, 108 eyes from 108 participants were submitted to clinical evaluations, including measurement of initial intraocular pressure (T1). The thermal mask was then applied for 10 minutes, followed by a second evaluation of intraocular pressure (T2) and assessment of any side effects. Results: The hypothermic group (G1) showed a significant reduction in mean intraocular pressure between T1 (16.97 ± 2.59 mmHg) and T2 (14.97 ± 2.44 mmHg) (p<0.001). G2 showed no significant pressure difference between T1 (16.50 ± 2.55 mmHg) and T2 (17.00 ± 2.29 mmHg) (p=0.054). G3 showed a significant increase in pressure from T1 (16.53 ± 2.69 mmHg) to T2 (18.58 ± 2.95 mmHg) (p<0.001). At T1, there was no difference between the three study groups (p=0.823), but at T2, the mean values of G3 were significantly higher than those of G1 and G2 (p<0.00). Conclusion: Temperature was shown to significantly modify intraocular pressure. Thermal masks allow the application of temperature in a controlled, reproducible manner. Further studies are needed to assess the duration of these effects and whether they are reproducible in patients with pathologies that affect intraocular pressure.

Clinical outcomes and significance of postoperative ultrasound biomicroscopy in patients with Boston type 1 keratoprosthesis

ABSTRACT Purpose: To determine the clinical outcomes in patients after type 1 Boston keratoprosthesis surgery and the significance of ultrasound biomicroscopy imaging for postoperative follow-up. Methods: This retrospective analysis included 20 eyes of 19 patients who underwent corneal transplantation with type 1 Boston keratoprosthesis between April 2014 and December 2021. Data on patient demographics, preoperative diagnosis, visual acuity, and postoperative clinical findings were analyzed. Results: Type 1 Boston keratoprosthesis implantation resulted in intermediate- and long-term positive outcomes. However, blindness and other serious complications such as glaucoma, retroprosthetic membrane formation, endophthalmitis, or retinal detachment also occurred. The use of ultrasound biomicroscopy imaging allowed for better evaluation of the back of the titanium plate, anterior segment structures, and the relationship of the prosthesis with surrounding tissues, which provided valuable postoperative information. Conclusion: Regular lifetime monitoring and treatment are necessary in patients who undergo Boston type 1 keratoprosthesis implantation for high-risk corneal transplantation. ultrasound biomicroscopy imaging can be a valuable imaging technique for the evaluation of patients with Boston type 1 keratoprosthesis, providing important information on anterior segment anatomy and potential complications. Further studies and consensus on postoperative follow-up protocols are required to optimize the management of patients with Boston type 1 keratoprosthesis.

Hyaluronic acid-mediated epithelial-mesenchymal transition of human lens epithelial cells via CD44 and TGF-β2

ABSTRACT Purpose: The epithelial-mesenchymal transition of human lens epithelial cells plays a role in posterior capsule opacification, a fibrotic process that leads to a common type of cataract. Hyaluronic acid has been implicated in this fibrosis. Studies have investigated the role of transforming growth factor (TGF)-β2 in epithelial-mesenchymal transition. However, the role of TGF-β2 in hyaluronic acid-mediated fibrosis of lens epithelial cell remains unknown. We here examined the role of TGF-β2 in the hyaluronic acid-mediated epithelial-mesenchymal transition of lens epithelial cells. Methods: Cultured human lens epithelial cells (HLEB3) were infected with CD44-siRNA by using the Lipofectamine 3000 transfection reagent. The CCK-8 kit was used to measure cell viability, and the scratch assay was used to determine cell migration. Cell oxidative stress was analyzed in a dichloro-dihydro-fluorescein diacetate assay and by using a flow cytometer. The TGF-β2 level in HLEB3 cells was examined through immunohistochemical staining. The TGF-β2 protein level was determined through western blotting. mRNA expression levels were determined through quantitative real-time polymerase chain reaction. Results: Treatment with hyaluronic acid (1.0 μM, 24 h) increased the epithelial-mesenchymal transition of HLEB3 cells. The increase in TGF-β2 levels corresponded to an increase in CD44 levels in the culture medium. However, blocking the CD44 function significantly reduced the TGF-β2-mediated epithelial-mesenchymal transition response of HLEB3 cells. Conclusions: Our study showed that both CD44 and TGF-β2 are critical contributors to the hyaluronic acid-mediated epithelial-mesenchymal transition of lens epithelial cells, and that TGF-β2 in epithelial-mesenchymal transition is regulated by CD44. These results suggest that CD44 could be used as a target for preventing hyaluronic acid-induced posterior capsule opacification. Our findings suggest that CD44/TGF-β2 is crucial for the hyaluronic acid-induced epithelial-mesenchymal transition of lens epithelial cells.

Choroiditis following severe acute respiratory syndrome coronavirus 2 infection in unvaccinated identical twins

ABSTRACT Unvaccinated identical twins developed bilateral anterior uveitis soon after the onset of coronavirus disease 2019 symptoms. During follow-up, both patients developed choroiditis, and one twine developed posterior scleritis and serous retinal detachment. Prompt treatment with oral prednisone ameliorated the lesions, and no recurrence was observed at the 18-month follow-up. Choroiditis may rarely be associated with severe acute respiratory syndrome coronavirus 2 infection, and it responds well to corticosteroid therapy. Although the exact mechanism is unknown, we hypothesize that the virus may act as an immunological trigger for choroiditis.

Anterior lamellar corneoscleral keratoplasty for the management of corneal thinning following treatment with mitomycin-C and interferon to treat highly suspected ocular surface squamous neoplasia: a case report

ABSTRACT A patient presented with corneoscleral thinning five months after the treatment of suspected ocular squamous surface neoplasia with mitomycin-C and interferon. For tectonic and aesthetic purposes, we decided to perform lamellar corneoscleral transplantation. The approach used established new tectonic support and corneal homeostasis. This technique might be an option in similar cases.

Unilateral hemi-central retinal artery occlusion as a presenting sign of Susac syndrome

ABSTRACT A young woman presented at our clinic with sudden visual loss in the right eye, recurrent vertigo, and right-sided tinnitus. We performed a complete ophthalmological evaluation. This revealed effects of the condition on the small arterioles of the peripheral retina. Susac syndrome is characterized by the clinical triad of retinal arteriolar occlusions, cochleovestibular manifestations, and encephalopathy (which can be identified by neuroimaging abnormalities). Early diagnosis and immunosuppressive therapy improved the patient's visual acuity and the remission of her other symptoms. Hemi-central retinal artery occlusion is an atypical neuro-ophthalmological finding in this disease. However, its identification as a sign of Susac syndrome may facilitate timely diagnosis and accurate treatment.
