ABSTRACT Aging and face sagging have many causes, and various techniques are used for treatment, including noninvasive procedures, such as focused ultrasound, which uses the principle of collagen regeneration by coagulative necrosis of the dermis layers using radiofrequency, but this procedure has complications. We reported a case of a 54-year-old female patient who complained of poor visual acuity in her right eye three days after a focused ultrasound facial aesthetic procedure, with the best visual acuity of 20/60. Biomicroscopy of the right eye revealed an acute cataract with three points of fibrosis extending from the posterior to the anterior capsule. The patient underwent phacoemulsification surgery with visual rehabilitation and improved vision of 20/20. We hypothesized that the occurrence of acute cataract was related to the inappropriate use of focused ultrasound.

Los pesticidas son un grupo de compuestos químicos que tienen diferentes acciones, insecticidas, fungicidas, herbicidas, rodenticidas. Luego de su aplicación el proceso de degradacion es lento. Pueden permanecer en el suelo y en las aguas subterráneas, contaminando el agua. El cambio climático transforma el proceso de degradación de los compuestos químicos, por la alteración de la composición del suelo, produciendo alteraciones en el ecosistema y la biodiversidad.El impacto de los pesticidas sobre la salud humana es un desafío por el gran potencial de daño que tienen. Desde el año 2004, se introduce en Paraguay las semillas geneticamente modificadas, acompañado de un gran incremento de las areas de cultivo y la utilizacion de pesticidas.Con el objetivo de revisar el estado del conocimiento actual sobre los efectos de estas sustancias quimicas, sobre los diferentes organos y sistemas en las poblaciones pediatricas y embarazadas, se realizo una revision descriptiva, abarcando las principales base de datos disponibles.Como objetivo secundario, considerando la extension de areas de cultivo en Paraguay, describir los resutlados de los estudios realizados en el pais. Los resultados de los estudios revisados muestran asociacion entre afectacion de diferentes organos, sistemas, de estas poblaciones y la exposcion ambiental, de las aguas y los alimentos. Algunos de estos resultados se replican en los realizados en las zonas de cultivo del pais.
Pesticides, such as insecticides, fungicides, herbicides, and rodenticides, are a group of chemical compounds that have different actions. After their application, the degradation process is slow. They can remain in the soil and groundwater, contaminating the water. Climate change transforms the process of degradation of chemical compounds, by altering soil composition, producing alterations in the ecosystem and biodiversity. The impact of pesticides on human health is challenging because of the great potential for harm they have. Since 2004, genetically modified seeds have been introduced in Paraguay, accompanied by a great increase in cultivation areas and pesticide use. To review the current state of knowledge about the effects of these chemical substances on the different organs and systems in pediatric and pregnant populations, a descriptive review was carried out, utilizing the main available databases. As a secondary objective, considering the extension of cultivation areas in Paraguay, we also described the results of studies carried out in the country. The results of the reviewed studies show an association between the involvement of different organ systems in these populations and environmental exposure, water, and food. Some of these results are replicated in those carried out in the country's growing areas.

Resumen Introducción : El objetivo de este estudio fue evaluar los efectos adversos y la respuesta inmune de anticuer pos IgG anti S1 SAEA-CoV-2 en el personal de Salud del Hospital del Milagro de la ciudad de Salta, posterior a recibir dos dosis de vacuna COVID-19. Métodos : Se realizó un estudio prospectivo de co horte desde marzo de 2021 hasta abril 2022. Se reco pilaron datos demográficos, clínicos, eventos adversos supuestamente atribuidos a la vacunación (ESAVI) y se tomaron dos muestras de sangre para medir los niveles de anticuerpos. Resultados : Participaron 408 voluntarios, 401 (98%) fueron vacunados con Sputnik- V. La edad promedio fue de 45.5 años con predominio del sexo femenino (71%). Los ESAVI fueron reportados en 188 (46.1%) y 121 (29.7%) luego de la primera y segunda dosis respectivamente (p<0.001). Estos eventos fueron mayormente de carácter leve y transitorios, más frecuentes luego de la primera dosis. El primer dosaje de anticuerpos fue positivo en 99% con una media de títulos de 9.7 (SD 3.7). El segundo dosaje fue positivo en 88% con una media de títulos de 6.4 (SD 4.4). Los participantes con antecedentes de infección y dosajes previos positivos mostraron títulos significativamente más altos de anticuerpos (p<0.001). Conclusión : Los ESAVI reportados fueron mayorita riamente leves y transitorios. La vacunación masiva y la administración de la dosis recomendada son esenciales para lograr una inmunidad colectiva efectiva. La mayoría de los trabajadores de la salud vacunados desarrollaron anticuerpos y aquellos que cursaron la enfermedad previa a la vacunación presentaron títulos significativos más elevados de anticuerpos.
Abstract Introduction : The aim of this study was to evaluate the adverse effects and immune response associated with IgG anti S1 SAEA-CoV-2 antibodies among health care workers at Señor del Milagro Hospital in Salta city, after receiving two doses of COVID-19 vaccine. Methods : A prospective cohort study was carried out from March 2021 to April 2022. Demographic, clinical data, adverse events supposedly attributed to vaccina tion (AEFIs) were collected and two samples were taken to measure serum antibody levels. Results : 408 volunteers participated, 401 (98%) were vaccinated with Sputnik-V. The average age was 45.5 years with a predominance of the female sex (71%). AEFIs were reported in 188 (46.1%) and 121 (29.7%) after the first and second doses respectively (p<0.001). These events were mostly mild and transient, more frequent after the first dose. The first antibody test was positive in 99% with a mean titer of 9.7 (SD 3.7). The second dosage was positive in 88% with a mean titer of 6.4 (SD 4.4). Participants with a history of infection and previous positive testing showed significantly higher antibody titers (p<0.001). Conclusion : The AEFIs reported were mostly mild and transient. Mass vaccination and administration of the recommended dose are essential to achieve effective herd immunity. The majority of vaccinated healthcare workers developed antibodies and those who had the disease prior to vaccination had significant antibody titers.

Background: Contraceptive use during a woman's reproductive years can help prevent unintended pregnancies, maternal deaths, and other non-reproductive problems. However, there is also a risk of running into various health challenges. The study aimed at finding out if women in the Greater Accra and Ashanti regions of Ghana encounter health issues during and after use of contraceptives was conducted. Methods: Questionnaires were administered to 600 women out of which 401 responses were carefully gleaned for analysis using SPSS version 25. The questionnaire probed side and adverse effects women encountered in their use of contraceptives as well as the types of contraceptives they preferred. Results: The study revealed that the use of contraceptives was widely prevalent, especially amongst women aged 21-30 years (61.8%). The preferred types of contraceptives were the oral-progestin only (42.9%) and combined oral contraceptives (31.4%). Spotting or bleeding between periods (menstrual-related) was the highest reported side effect (33.2%), followed by weight gain (metabolic-related), 21.7%. Pearson’s Chi squared test showed an association between the age of respondents and the choice of contraceptive type at p<0.01. Hypertension and deep vein thrombosis (DVT) were the highest reported adverse effect (10.2% and 9.2% respectively). Conclusions: It was concluded that contraceptive use (especially the oral type) may cause discomfort with the side effects reported in women of reproductive age and it may be a contributing factor to other health conditions in susceptible women.

Background: Metformin, a first-line agent in Type 2 diabetes mellitus, causes gastrointestinal adverse effects in 20-30% of patients, leading to discontinuation in 5-10% of them. Organic cation transporter 1 (OCT1) encoded by SLC22A1, transports metformin from the enterocytes into the bloodstream. Reduced function OCT1 variants could lead to increased luminal concentration of metformin leading to gastrointestinal adverse effects. Two single nucleotide polymorphisms in the SLC22A1 gene were studied in this cross-sectional study with cases and controls. Objective was to determine the association between genetic polymorphisms rs628031 (1222A>G) and rs622342 (1386C>A) in SLC22A1 gene and gastrointestinal adverse effects to metformin therapy in South Indian type 2 diabetes mellitus patients. Methods: The study was conducted in JIPMER, Puducherry, India in T2DM patients (n=300) of South Indian origin, who were categorized into case (N=100) and control (N=200) groups, based on their gastrointestinal tolerance to metformin. DNA was extracted from the patients using whole blood by phenol-chloroform method and genotyping was done using real-time PCR. Results: Minor allele frequency of rs628031 (A allele) and rs622342 (C allele) were 33.8% and 26.5% respectively. Genotype frequencies did not differ significantly between the case and control groups (rs628031, p=0.45, rs622342, p=0.28). Female gender (AOR 3.77; 95% CI 2.07, 6.85; p<0.001) and proton pump inhibitor usage (AOR 7.66; 95% CI 3.01, 19.47; p<0.001) had higher association with metformin intolerance. Conclusions: No significant association was found between the genotypes of single nucleotide polymorphisms (rs628031 and rs622342) in the SLC22A1 gene and gastrointestinal adverse effects to metformin therapy in South Indian type 2 diabetes mellitus patients.

Introducción: Sulfato de magnesio (MgSO4) y aminofilina son broncodilatadores intravenosos utilizados en el tratamiento de niños con broncoobstrucción (BO). La evidencia disponible para recomendar su uso es escasa. Objetivo: Caracterizar el perfil de uso y la respuesta terapéutica al MgSO4 y aminofilina en el tratamiento de la BO en niños hospitalizados en un centro de referencia de Uruguay. Materiales y métodos: Estudio descriptivo de corte transversal mediante revisión de historias y entrevistas. Se incluyeron a todos los menores de 15 años que utilizaron estos fármacos. Se evaluó la respuesta terapéutica a la administración de ambos fármacos en forma exclusiva y concomitante y la presencia de efectos adversos. Resultados: Se incluyeron 102 niños, mediana de edad 4 años, ≤5 años 62%. Los principales diagnósticos fueron: crisis asmática 56% y neumonía viral 31%. Recibieron ambos fármacos 48%, únicamente aminofilina 28% y exclusiva de MgSO4 24%. Se observó buena respuesta terapéutica a la administración: exclusiva de MgSO4 67%, consecutiva de MgSO4 y aminofilina 45% y exclusiva de aminofilina en 34%. En 38,2% se registró al menos un efecto adverso, 64% eran menores de 5 años, riesgo aumentado en 1,5 veces. Conclusiones: Se registraron variadas indicaciones, la mayoría en niños asmáticos y en un porcentaje menor indicaciones fuera de prospecto. Menos de la mitad presentaron buena respuesta luego de la administración de MgSO4 y/o aminofilina. En un porcentaje no despreciable se registraron efectos adversos, predominaron en menores de 5 años. Son necesarios nuevos estudios para continuar caracterizando el perfil de uso y seguridad de estos fármacos.
Introduction: Magnesium sulfate (MgSO4) and aminophylline are intravenous bronchodilators used in the treatment of children with bronchoobstruction (BO). The evidence available to recommend their use is scarce. Objective: To characterize the use profile and therapeutic response to MgSO4 and aminophylline in the treatment of BO in children hospitalized in a reference center in Uruguay. Materials and methods: This was a descriptive cross-sectional study through review of clinical histories and interviews. All children under 15 years of age who used these drugs were included. The therapeutic response to the administration of both drugs exclusively and concomitantly and the presence of adverse effects were evaluated. Results: 102 children were included, median age was 4 years, 62% were ≤5 years. The main diagnoses were: asthmatic crisis, 56% and viral pneumonia, 31%. 48% received both drugs, 28% only aminophylline and 24% exclusively MgSO4. Good therapeutic response was observed to the administration: MgSO4 exclusively, 67%, MgSO4 followed by aminophylline, 45% and aminophylline exclusively in 34%. At least one adverse effect was recorded in 38.2%, of these, 64% were under 5 years of age, risk increased by 1.5 times. Conclusions: Various indications were recorded, the majority in asthmatic children and a smaller percentage off-label indications. Less than half had a good response after the administration of MgSO4 and/or aminophylline. Adverse effects were recorded in a non-negligible percentage, predominating in children under 5 years of age. New studies are necessary to continue characterizing the use and safety profile of these drugs.

RESUMEN Inicialmente desarrollados como medicamentos para la diabetes mellitus, los agonistas GLP-1 han ganado mucha popularidad en el tratamiento de la obesidad y la pérdida de peso. El presente caso describe a una mujer de 69 años con antecedente de úlcera péptica y consumo de AINES, quien cursó con dolor abdominal e intolerancia oral refractaria al manejo convencional, por lo que se realizó una endoscopía digestiva alta, diagnosticándose gastroparesia severa. Al ampliar la anamnesis, se reveló el uso subrepticio de semaglutida. Se continuó con terapia de soporte y los síntomas remitieron espontáneamente. El presente reporte de caso tiene como objetivo advertir los riesgos potenciales del uso de análogos de GLP-1 en el contexto de una endoscopía con sedación.
ABSTRACT Initially developed as medications for diabetes mellitus, GLP-1 agonists have gained much popularity in the treatment of obesity and weight loss. The present case describes a 69-yearold woman with a history of peptic ulcer and use of NSAIDs, who presented with abdominal pain and oral intolerance refractory to conventional management, for which an upper digestive endoscopy was performed, diagnosing severe gastroparesis. Asking more about the story, revealed surreptitious use of semaglutide. She continued with supportive therapy and the symptoms resolved spontaneously. The present case report aims to warn of the potential risks of the use of GLP-1 analogues in the context of endoscopy with sedation.

ObjectiveTo investigate the efficacy and safety of cinobufagin tablets combined with thalidomide/dexamethasone (TD) regimen in the treatment of newly diagnosed multiple myeloma (NDMM) with phlegm and stasis obstruction. MethodsThe clinical data of 50 patients with NDMM of phlegm and stasis obstruction who were hospitalized at the Jiangsu Province Hospital of Chinese Medicine from June 1st, 2015 to July 31th, 2019 were retrospectively analyzed, and they were divided into a control group (bortezomib/dexamethasone-containing regimen, 27 cases) and an observation group (cinobufagin tablets combined with TD regimen, 23 cases). The clinical efficacy and safety were compared between the two groups after two or three courses of treatment. The primary outcomes were clinical remission rate including overall response rate and deep remission rate, one-year and two-year overall survival rate, and adverse effects. The secondary outcomes were the proportion of plasma cells in bone marrow, hemoglobin, β2-microglobulin, lactate dehydrogenase, serum creatinine, blood urea nitrogen, bone pain score, and KPS functional status score (KPS score) before and after treatment. ResultsIn terms of clinical efficacy, there was no statistically significant difference (P>0.05) in the overall response rate [the observation group 69.57%(16/23) vs the control group 70.37% (19/27)] and deep remission rate [the observation group 56.52% (13/23) vs the control group 55.56% (15/27)] between groups after the treatment. The one-year overall survival rates of the observation group and the control group were 90.9% and 92.4%, and the two-year overall survival rates were 81.8% and 80.9% respectively, with no statistically significant differences between groups (P>0.05). During the treatment, no renal function injury occurred in both groups. The incidence of peripheral nerve injury in the observation group was 8.70%, which was lower than 48.15% in the control group (P<0.01). After the treatment, the proportion of myeloma plasma cells, β2-microglobulin, serum creatinine level, and bone pain score decreased, while the hemoglobin level and KPS score increased in both groups (P<0.05 or P<0.01). Compared between groups after treatment, the bone pain score of the observation group was lower than that of the control group, while the KPS score was higher than that of the control group (P<0.05). ConclusionThe clinical efficacy of cinobufagin tablets combined with TD in the treatment of NDMM is equivalent to bortezomib/dexamethasone-containing regimen, but the former is more helpful in relieving the pain and improving the quality of life, and has better safety.

@#Myogenous temporomandibular disorder (M-TMD) is one of the main subtypes of temporomandibular disorder (TMD) and typically manifests as masticatory myofascial pain; the incidence of TMD has been increasing annually in recent years. Botulinum toxin type A (BTX-A) is a potent neurotoxin produced by Clostridium botulinum. BTX-A inhibits the release of acetylcholine from the presynaptic membrane, thereby blocking neuromuscular junction signaling. The noncosmetic application of BTX-A in the oral and maxillofacial regions is a prominent research topic. In recent years, an increasing number of studies have focused on the application of BTX-A in the treatment of M-TMD. The results of a literature review revealed that an appropriate dose (10-50 U unilaterally) of BTX-A administered in a single injection into the masticatory muscles can effectively treat myalgia over a period of 3-6 months. Common adverse effects, such as masticatory weakness and facial paralysis, are transient and can be avoided by standardized injection techniques. However, there is a lack of standardized guidelines for injection techniques in clinical practice.

ABSTRACT We present a case of a patient complaining of monocular diplopia due to a decentered ablation after LASIK. The patient underwent a wavefront-guided retreatment, which resulted in an epithelial ingrowth complication. Additionally, the patient developed cataract, with cataract surgery requiring reliable biometric measurements. Therefore, we opted for corneal treatment and corneal surface regularization. Although we attempted to lift the flap and wash the interface initially, the procedure proved unsuccessful, thereby necessitating immediate flap amputation. Once the corneal surface was regularized in the seventh postoperative month, transepithelial photorefractive keratectomy was successfully performed to homogenize the ocular surface, thereby significantly improving the patient's corrected visual acuity and resolving monocular diplopia. The surface and corneal curvature stabilized by the fifth month after the procedure. Phacoemulsification was then performed along with the implantation of a toric monofocal lens, which was selected using an appropriate formula, resulting in an excellent uncorrected visual acuity.

Abstract Although kidney transplantation is the best therapeutic option for patients with chronic kidney disease, the immunosuppression required greatly increases susceptibility to infections that are responsible for high post-transplant mortality. Pulmonary tuberculosis (TB) represents a major cause of such infections, and its early diagnosis is therefore quite important. In view of that, we researched the manifestations of active pulmonary TB in kidney transplant recipients, through chest X-ray and computed tomography (CT), as well as determining the number of cases of active pulmonary TB occurring over a 3.5-year period at our institution. We identified four cases of active pulmonary TB in kidney transplant recipients. The CT scans provided information complementary to the chest X-ray findings in all four of those cases. We compared our CT findings with those reported in the literature. We analyzed our experience in conjunction with an extensive review of the literature that was nevertheless limited because few studies have been carried out in lowand middle-income countries, where the incidence of TB is higher.
Resumo Apesar de o transplante renal ser a melhor opção terapêutica para pacientes com doença renal crônica, a imunodepressão decorrente desse tratamento eleva muito a suscetibilidade desses pacientes a infecções, responsáveis por altas taxas de mortalidade pós-operatórias. A tuberculose (TB) pulmonar é uma significativa causa dessas infecções, sendo muito importante o seu diagnóstico precoce. Assim, nós pesquisamos as manifestações da TB pulmonar ativa nessa população de transplantados renais por meio de radiografias simples e tomografia computadorizada (TC) do tórax, também para estabelecer o número de casos de TB pulmonar ativa em nossa instituição após levantamento de 3,5 anos. Encontramos quatro casos de TB pulmonar ativa em pacientes transplantados renais. A TC forneceu informações adicionais em relação às radiografias de tórax em 100% dos casos analisados. Comparamos os nossos achados de TC com os relatados na literatura. Somamos a experiência obtida com extensa revisão da literatura, ainda limitada nessa questão, com poucos estudos realizados em países em desenvolvimento onde a incidência de TB é maior.

ABSTRACT Maculopathy from prolonged exposure to solar light is a rare but well-recognized clinical entity of vision loss and macular damage. Photochemical damage precedes visual decline, and in mild cases, vision usually returns fully or partially. With the advancement of humanity, other forms of macular injuries induced by light radiation have emerged, increasing the group of photic maculopathies. In this report, we describe the cases of five patients where a diagnosis of photic maculopathy was made based on the anamnesis, clinical findings, and complementary exams. We compare the five cases regarding their similarities and differences, as well as review the literature on the subject.
RESUMO A maculopatia causada pela exposição prolongada à luz solar é uma entidade clínica rara, mas bem reconhecida, de perda de visão e dano macular. O dano fotoquímico precede o declínio visual e em casos leves a visão geralmente retorna total ou parcialmente. Com o avanço da humanidade, surgiram outras formas de lesões maculares induzidas pela radiação luminosa, aumentando o grupo das maculopatias fóticas. Neste relato, descrevemos os casos de cinco pacientes onde o diagnóstico de maculopatia fótica foi feito com base na anamnese, achados clínicos e exames complementares. Comparamos os quatro casos quanto às suas semelhanças e diferenças, bem como revisamos a literatura sobre o assunto.

ABSTRACT A 51-year-old non-obese woman presented with a one-week history of progressive blurry vision within the inferior visual field of her left eye. Her only relevant past medical history was long-standing hypothyroidism and recent vaccination against Coronavirus Disease 2019 (COVID-19) with an mRNA vaccine 12 days before the onset of symptoms. At examination, the anterior segment was unremarkable, but the retinal fundus revealed a central retinal vein occlusion associated with a branch retinal artery occlusion of the superior temporal branch in her left eye. Ancillary tests to rule out thrombophilia, hyperviscosity, hypercoagulability, or inflammation were negative. Ultrasound tests were also negative for a cardiac or carotid origin of the branch retinal artery occlusion. At two-month follow-up, no new retinal vascular occlusive events were observed. Although the best-corrected visual acuity at presentation was 8/10 in the left eye, the final best-corrected visual acuity remained 3/10.
RESUMO Uma mulher de 51 anos, não obesa, apresentou história de uma semana de visão embaçada progressiva no campo visual inferior do olho esquerdo. Seu único histórico médico anterior relevante era hipotireoidismo de longa data e uma recente vacinação contra a Doença de Coronavírus 2019 (COVID-19), com vacina de mRNA, 12 dias antes do início dos sintomas. O exame mostrou segmento anterior normal, mas o fundo da retina revelou uma oclusão da veia central da retina associada a uma oclusão de ramo arterial da retina do ramo temporal superior no olho esquerdo. Testes auxiliares para descartar trombofilia, hiperviscosidade, hipercoagulabilidade ou inflamação apresentaram resultados negativos. Testes de ultrassom também foram negativos quanto a uma origem cardíaca ou da carótida da oclusão do ramo da artéria da retina. Após dois meses de acompanhamento, nenhum novo evento vascular oclusivo retiniano foi observado. Embora, a acuidade visual melhor corrigida na apresentação tenha sido de 8/10 no olho esquerdo, a acuidade visual final melhor corrigida permaneceu em 3/10.

ABSTRACT Primary graft failure (PGF) is a known complication following penetrating keratoplasty (PKP). The usual approach to treat this complication is to repeat a penetrating keratoplasty. Here, we report a case of Descemet's membrane endothelial keratoplasty (DMEK) for the treatment of PGF after PKP. A patient that underwent PKP, developed PGF with persistent graft edema and very poor visual acuity despite aggressive steroid use and a proof anti-viral treatment. Three months after the initial surgery, a DMEK was performed under the PKP graft. There was progressive early corneal clearing and, by the end of the first month, the patient already had no corneal edema. Uncorrected visual acuity (UCVA) improved to 20/40 and best corrected visual acuity (BCVA) to 20/20. DMEK may be an alternative to a second PKP for the treatment of PGF. This technique is a less invasive option when compared to the standard PKP procedure.
RESUMO A falência primária do enxerto é uma complicação conhecida que pode ocorrer após o transplante penetrante de córnea. O tratamento usual dessa complicação é com um novo transplante penetrante. Apresentamos um caso em que foi usado o transplante endotelial de membrana de Descemet (DMEK - do inglês Descemet membrane endo-thelial keratoplasty) para o tratamento da falência primária após o transplante penetrante. Uma paciente submetida a transplante penetrante evoluiu com falência primária do enxerto a despeito do uso intenso de corticoide tópico e uma prova terapêutica de antivirais. Três meses após a cirurgia inicial, foi optado pela realização do transplante endotelial de membrana de Descemet sob o transplante penetrante. Houve um clareamento precoce e progressivo do enxerto com melhora importante da visão. Após um mês, a visão sem correção era de 20/40 melhorando para 20/20 com refração. O transplante endotelial de membrana de Descemet pode ser uma alternativa a um novo transplante penetrante como tratamento da falência primária.

ABSTRACT Objective: To guide professionals about the criteria for replacing amalgam restorations and inform them about the new guidelines regarding the use/indication of this (amalgam) material after the Minamata Convention - COP-4. Material and Methods: The articles were selected from the databases (PubMed, Scielo, Bireme), and relevant articles on the subject between the years 2003-2021 were selected. Recently, social media have been flooded with dental treatments that aim to perform restorations only with composite resins or other types of esthetic material and completely replace all dental amalgam restorations, irrespective of their time in place, size, and functionality. Results: Although improperly, it has been noted that this information reaches patients, and they are led to believe in the inaccurate data that is passed on, such as, for example, (that amalgam leads to) permanent contamination by mercury, causing systemic problems and the loss of the tooth. Conclusion: The "phase down" of amalgam in research and teaching has previously been observed in several countries worldwide; however, its use is still necessary given particular circumstances, which, theoretically, make it a material with exact indication.

ABSTRACT Purpose: To evaluate the effect of tobacco smoking on trabeculectomy outcomes. Methods: Charts of patients with glaucoma who underwent trabeculectomy performed by a single surgeon between 2007 and 2016 were retrospectively reviewed. Charts were screened for a documented history of smoking status before surgery. Demographic and clinical preoperative variables were recorded. Based on smoking history, subjects were divided into two groups: smokers and nonsmokers. Any bleb-related interventions (e.g., 5-flourouracil injections ± laser suture lysis) or bleb revision performed during the postoperative period were noted. Success was defined as an intraocular pressure >5 mmHg and <21 mm Hg without (complete success) or with (qualified success) the use of ocular hypotensive medications. Failure was identified as a violation of the criteria mentioned above. Results: A total of 98 eyes from 83 subjects were included. The mean age of the subjects was 70.7 ± 11.09 years, and 53% (44/83) were female. The most common diagnosis was primary open-angle glaucoma in 47 cases (47.9%). The smokers Group included 30 eyes from 30 subjects. When compared with nonsmokers, smokers had a significantly worse preoperative best-corrected visual acuity (p=0.038), greater central corneal thickness (p=0.047), and higher preoperative intraocular pressure (p=0.011). The success rate of trabeculectomy surgery at 1 year was 56.7% in the smokers Group compared with 79.4% in the Group nonsmokers (p=0.020). Smoking presented an odds ratio for failure of 2.95 (95% confidence interval, 1.6-7.84). Conclusion: Smokers demonstrated a significantly lower success rate 1 year after trabeculectomy compared with nonsmokers and a higher requirement for bleb-related interventions.
RESUMO Objetivo: Avaliar o efeito do tabagismo nos desfechos da trabeculectomia. Métodos: Uma revisão retrospectiva do gráfico de pacientes com glaucoma submetidos à trabeculectomia foi realizada por um único cirurgião entre 2007 e 2016. Os gráficos foram examinados para uma história documentada de condição de fumante antes da cirurgia. Variáveis pré-operatórias clínicas e demográficas e clínicas foram registradas. Os pacientes foram divididos em dois grupos de acordo com sua história de tabagismo em fumantes e não fumantes. Quaisquer Intervenções relacionadas à bolha, por exemplo, injeções de 5-fluorouracil + lise de sutura com laser, ou revisão da bolha realizada durante o período pós-operatório foram observadas. O sucesso foi definido como pressão intraocular > 5 mmHg e < 21 mm Hg sem (sucesso completo) ou com (sucesso qualificado) medicamentos hipotensores oculares. A falha foi identificada como violação dos critérios mencionados acima. Resultados: O estudo incluiu 98 olhos de 83 pacientes com idade média de 70,7 ± 11,09 anos, sendo 53% (44/83) dos pacientes do sexo feminino. O diagnóstico mais comum foi o glaucoma de ângulo aberto primário com 47 casos (47,9%). O Grupo de fumantes incluiu 30 olhos de 30 pacientes. Os fumantes, quando comparados aos não fumantes, apresentaram uma melhor acuidade visual pré-operatória significativamente pior (p=0,038), maior espessura central da córnea (p=0,047) e maior pressão intraocular pré-operatória (p=0,011). A taxa de sucesso de um ano para a cirurgia de trabeculectomia foi de 56,7% no Grupo de fumantes contra 79,4% no Grupo de não fumantes (p=0,020). O tabagismo apresentou razão de chances para falha de 2,95 95% de IC (1,6-7,84). Conclusão: Os fumantes demonstraram uma taxa de sucesso significativamente menor em um ano após a trabeculectomia em comparação com os não fumantes e uma maior necessidade de intervenções relacionadas à bolha.

ABSTRACT Purpose: This study aimed to screen the ocular surface of children with attention deficit hyperactivity disorder and identify the adverse effects of methylphenidate related to dry eye disease. Methods: This cross-sectional study included children with attention deficit hyperactivity disorder and healthy children (all aged 5-18 years). They were randomized into Group A (without methylphenidate treatment), Group B (with methylphenidate treatment), and Group C (healthy children). Tear film break-up time, Ocular Surface Disease Index questionnaire, tear meniscus height, tear meniscus area, and Schirmer test results were evaluated. Furthermore, symptom severity in attention deficit hyperactivity disorder was assessed by Turgay DSM-IV-based Child and Adolescent Behavioral Disorders Screening and Rating Scale and Conners Parent Rating Scale-48. Results: Groups A, B, and C consisted of 34, 40, and 60 individuals (n=34, 40, and 60 eyes; age=11.44 ± 2.79, 11.70 ± 2.83, and 11.96 ± 3.63 years, median age=12, 12, and 11.5 years), respectively. Tear film break-up time, Ocular Surface Disease Index, tear meniscus height, tear meniscus area, and Schirmer test results were not significantly different between Groups A and C (p=0.964, 0.336, 0.445, 0.439, and 0.759, respectively). However, Group B showed a significant decrease in tear film break-up time (10.50 ± 3.39 vs. 12.52 ± 2.46 s; p=0.005), tear meniscus height (307.40 ± 5.53 vs. 310.82 ± 7.30 µm; p=0.025), tear meniscus area (0.024 ± 0.0037 vs. 0.026 ± 0.0046 mm2; p=0.010) and Schirmer test (12.75 ± 3.96 vs. 15.41 ± 3.75 mm; p=0.004) results compared with Group A. Conclusion: Compared with healthy children, children with attention deficit hyperactivity disorder showed ocular surface parameters suggestive of dry eye disease despite taking methylphenidate. Thus, they require close ophthalmologic follow-up to prevent sight-threatening dry eye complications.
RESUMO Objetivos: Este estudo teve como objetivo examinar a superfície ocular de crianças com transtorno de déficit de atenção com hiperatividade e identificar os efeitos adversos do metilfenidato relacionados à síndrome do olho seco. Métodos: Este estudo transversal incluiu crianças com transtorno de déficit de atenção e hiperatividade e crianças saudáveis (todas entre 5-18 anos de idade). Elas foram randomizadas no Grupo A (sem tratamento com metilfenidato), Grupo B (com tratamento com metilfenidato) e Grupo C (crianças saudáveis). Foram avaliados o tempo de ruptura do filme lacrimal, questionário sobre Índice de Doenças de Superfície Ocular (IDSO), altura do menisco lacrimal, área do menisco lacrimal e os resultados do teste de Schirmer. Além disso, a gravidade dos sintomas no transtorno de déficit de atenção com hiperatividade foi avaliada usando a Turgay DSM-IV-based Child and Adolescent Behavioral Disorders Screening and Rating Scale com base na escala de Conners Parent Rating Scale-48. Resultados: Os Grupos A, B e C consistiram de 34, 40 e 60 indivíduos (n=34, 40 e 60 olhos; idade=11,44 ± 2,79, 11,70 ± 2,83 e 11,96 ± 3,63 anos, idade média=12, 123 e 11,5 anos), respectivamente. O tempo de ruptura do filme lacrimal, o Índice de Doença da Superfície Ocular, as altura do menisco lacrimal, a área do menisco lacrimal e o teste de Schirmer não foram significativamente diferentes entre os Grupo A e C (p=0,964, 0,336, 0,445, 0,439 e 0,759, respectivamente). Entretanto, o Grupo B mostrou uma redução significativa no tempo de ruptura do filme lacrimal (10,50 ± 3,39 vs 12,52 ± 2,46 seg; p=0,005), altura do menisco lacrimal (307,40 ± 5,53 vs 310,82 ± 7,30 µm; p= 0,025), área do menisco lacrimal (0,024 ± 0,0037 vs 0,026 ± 0,0046 mm2; p=0,010) e teste de Schirmer (12,75 ± 3,96 vs 15,41 ± 3,75 mm; p=0,004), resultados com0arados com o Grupo A. Conclusão: Em comparação com crianças saudáveis, crianças com transtorno de déficit de atenção com hiperatividade apresentaram parâmetros de superfície ocular sugestivos de olho seco, apesar do uso de metilfenidato. Assim, elas requerem um acompanhamento oftalmológico próximo para evitar complicações oculares de olho seco que ameaçam a visão.

Abstract Introduction Low-Level Red-Light (LLRL) Therapy is a safe and natural way to promote healing and reduce inflammation in the body. When it comes to treating myopia in children, LLRL therapy is recent, and its efficacy and safety still are not clear. Methods A systematic review and meta-analysis of the literature for LLRL was conducted in accordance with the PRISMA guidelines on November 5, 2022. Databases, including PUBMED, Cochrane Library, Web of Science, and Embase were queried. A meta-analysis of random effects was conducted. Inclusion criteria included Randomized Controlled Trials (RCTs) or observational studies where LLRL therapy was used in children (3‒15 years old) with myopia. Exclusion criteria were studies with other ocular abnormalities. Efficacy was evaluated through the mean change in Axial Length (AL) and cycloplegic Spherical Equivalent Error (SER), while safety was evaluated by monitoring adverse effects. Results A total of 5 final studies were included (4 RCTs, and 1 observational), in which 685 total patients were analyzed. The mean age was 9.7 ± 0.66 years, with 48,2% female patients. The number of eyes in the LRLL arm is 714 and, in the control, arm is 656. LLRL showed better results in SER and AL mean change (OR = 0.58; 95% CI 0.33 to 0.83; p < 0.00001, and MD -0.33; 95% CI -0.52 to -0.13; p = 0.001, respectively), in comparison to the control group. There was no significant difference in adverse effects between groups (MD = 5.76; 95% CI 0.66 to 50.14; p = 0.11). Conclusion LLRL therapy is a non-invasive, effective, and safe short-term treatment option; however, long-term evaluation, particularly in comparison to other therapies, requires additional investigation.
