RESUMO

ABSTRACT Purpose: Information is scarce regarding the comprehensive profile of patients with essential blepharospasm and hemifacial spasm in Brazil. The present study aimed to assess the clinical features of patients with these conditions, followed up in two reference centers in Brazil. Methods: The study included patients with essential blepharospasm and hemifacial spasm, followed up at the Departments of Ophthalmology at Universidade Federal de São Paulo and Universidade de São Paulo. Apart from demographic and clinical features, past stressful events related to the first symptoms (triggering event), aggravating factors, sensory tricks, and other ameliorating factors for the eyelid spasms were assessed. Results: A total of 102 patients were included in this study. Most patients were female (67.7%). Essential blepharospasm was the most frequent movement disorder [51/102 patients (50%)], followed by hemifacial spasm (45%) and Meige's syndrome (5%). In 63.5% of the patients, the onset of the disorder was associated with a past stressful event. Ameliorating factors were reported by 76.5% of patients; 47% of patients reported sensory tricks. In addition, 87% of the patients reported the presence of an aggravating factor for the spasms; stress (51%) was the most frequent. Conclusion: Our study provides information regarding the clinical features of patients treated in the two largest ophthalmology reference centers in Brazil.


RESUMO Objetivo: Há poucos dados sobre o perfil de pacientes com blefaroespasmo essencial e espasmo hemifacial no Brasil. O objetivo deste estudo é avaliar de forma mais abrangente as características clínicas dos pacientes portadores dessas doenças acompanhados em dois centros de referência em oftalmologia no Brasil. Métodos: Pacientes com blefaroespasmo essencial e espasmo hemifacial, acompanhados nos Departamentos de Oftalmologia da Universidade Federal de São Paulo e da Universidade de São Paulo foram incluídos neste estudo. Além dos dados clínicos e demográficos, foram avaliados também a presença de eventos estressantes relacionados ao início dos sintomas (evento desencadeante), fatores agravantes, truques sensoriais, e outros fatores de melhora. Resultados: Cento e dois pacientes foram incluídos no estudo. A maior parte dos pacientes era do sexo feminino (67,7%). Blefaroespasmo essencial foi a condição mais frequente, observada em 51 (50%) dos pacientes. Espasmo hemifacial correspondia a 45% dos casos, enquanto 5% dos pacientes apresentavam a Síndrome de Meige. 63,5% dos pacientes associaram o início dos sintomas com um evento estressante prévio. 76,5% dos pacientes relataram fatores de melhora para os espasmos; 47% relataram truques sensoriais. Além disso, 87% dos pacientes relataram fatores de piora; estresse (51%) foi o mais frequente. Conclusão: Este estudo fornece informações a respeito das características clínicas dos pacientes com blefaroespasmo essencial e espasmo hemifacial acompanhados nos dois maiores centros de referência em oftalmologia do Brasil.

RESUMO

ABSTRACT Purpose: To evaluate the variables possibly related to actinic keratosis and malignant skin lesions on the eyelid. Methods: A prospective study of patients with suspected eyelid malignancy was conducted. The participants underwent a 2-mm punch biopsy at two opposite sites of the lesion for diagnosis, and the results were compared with those of the histopathological study of the surgical excised specimen. The patients with an actinic keratosis component were divided into two groups (actinic keratosis-associated malignancy and actinic keratosis alone), which were compared for the following variables: age, disease duration, largest diameter, tumor area, Fitzpatrick classification, sex, tumor site and margin involvement. A cluster analysis was also performed. Results: We analyzed 174 lesions, of which 50 had an actinic keratosis component. Actinic keratosis was associated with squamous cell carcinoma in 22% of the cases and to basal cell carcinoma in 38%, which shows that both neoplasms may have contiguous actinic keratosis. Statistical analysis revealed no significant difference among the variables. In a cluster analysis, four groups were identified with malignant lesions in the medial canthus with the largest mean diameter and area. All margin involvements on the lower eyelid were related to malignancy, which means that all cases with margin involvement had an almost 100% risk of malignancy. Conclusions: Larger actinic keratosis lesions in the medial canthus and lesions with margin involvement on the lower eyelid have a greater probability of malignant association.


RESUMO Objetivo: Avaliar as possíveis variáveis relacionadas à ceratose actínica e lesões malignas cutâneas nas pálpebras. Métodos: Estudo prospectivo de pacientes com lesões palpebrais suspeitas de malignidade. Os participantes foram submetidos à biopsia por trépano (punch) de 2-mm em dois pontos opostos da lesão como método diagnóstico e os resultados foram comparados com o estudo histopatológico da peça excisada cirurgicamente. Aqueles que apresentaram ceratose actínica como resultado foram divididos em dois grupos (ceratose actínica associada com malignidade e ceratose actínica isolada) e foram comparados de acordo com as variáveis: idade, tempo de doença, maior diâmetro, área do tumor, classificação de Fitzpatrick, gênero, localização e acometimento da margem palpebral. A análise de cluster também foi realizada. Resultados: Foram analisadas 174 lesões e 50 delas tinham ceratose actínica como componente do tumor. Ceratose actínica esteve associada ao Carcinoma Espinocelular em 22% dos casos e ao Carcinoma Basocelular em 38%, mostrando que ambos podem ter ceratose actínica adjacente. A análise estatística não encontrou diferença entre as variáveis. A análise de cluster identificou quatro grupos e mostrou que lesões malignas no canto medial tinham maiores diâmetro e área. Acometimento da margem na pálpebra inferior relacionou-se em 100% com malignidade, enquanto a ausência de acometimento da margem mostrou menor chance de malignidade. Conclusões: Lesões maiores de ceratose actínica no canto medial e lesões com acometimento da margem palpebral inferior têm maiores chances de associação com malignidade.

RESUMO

BACKGROUND AND PURPOSE: It is challenging to assess essential blepharospasm (EB) patients objectively because they exhibit chaotic patterns of abnormal eyelid movements. Previously employed objective approaches used systems with low levels of accuracy systems or were too complex to be applied in routine clinical practice. We aimed to develop a practical tool using a smartphone camera and custom-made software to objectively assess the therapeutic effects of botulinum toxin in blepharospasm patients. METHODS: Thirty-four patients with EB were evaluated before and 15 days after receiving onabotulinumtoxinA injections. The control group was composed of 19 age-matched healthy individuals. A smartphone (iPhone 6 S; Apple) was used to record spontaneous eyelid movements for 3 min, after which eyelid movement frequency was analysed using custom-made software. RESULTS: Before treatment, eyelid movement frequency was significantly higher in the EB group (21.55 ± 13.30 movements/min) compared to the control group (8.26 ± 8.89 eyelid movements/min; p < 0.001). The frequency of spontaneous eyelid movements was significantly reduced after treatment in the EB patients (8.46 ± 6.32 eyelid movements/min; p < 0.001). After treatment, no statistically significant difference in eyelid movement rate was observed between the EB patients and the control group (p = 0.32). CONCLUSIONS: Assessment of the spontaneous eyelid movements obtained with the smartphone camera and analysed with the custom-made software enabled us to objectively measure the therapeutic effects of botulinum toxin in patients with blepharospasm. Further refinement of this system could enable customized and fine adjustments to botulinum toxin doses based on each patient's needs.

RESUMO

ABSTRACT Dermal filler injection is among facial rejuvenation treatments that have been increasingly used. Despite being a minimally invasive procedure, it can lead to severe complications such as blindness. A review of all cases of filler- -induced visual loss in the world literature was conducted to summarize the mechanisms, anatomical considerations, and clinical ophthalmologic course, current strategies of prevention and management, and trends over the years. We identified 233 cases of filler-induced visual loss, and 172 patients had a severe visual impairment in at least one eye. The typical patients are young women who received injections of hyaluronic acid or autologous fat in the glabella or nose, and the typical presentations were sudden ocular pain, ptosis, and ophthalmoplegia due to vascular occlusion. The findings of this study also suggest an increase in the number of unlicensed professionals performing the procedure. Even though the continued development of dermal fillers has improved the treatment options available, further studies and strategies are necessary to reduce the incidence and minimize the consequences of filler-induced visual loss.


RESUMO O uso de preenchedores dérmicos é uma prática bem estabelecida de rejuvenescimento facial. Embora seja um procedimento minimamente invasivo, pode levar a complicações graves como cegueira. Uma revisão de casos de perda visual pós preenchimento facial estético foi conduzida para descrever os mecanismos, considerações anatômicas, quadro oftalmológico, atuais estratégias de prevenção e manejo, e tendências ao longo dos anos. Foram identificados 233 casos, e 172 pacientes tiveram ao menos um olho com baixa visão ao final do seguimento. O paciente típico é uma mulher jovem submetida a preenchimento de ácido hialurônico na glabela ou nariz, apresentando dor ocular súbita, ptose e oftalmoplegia devido à oclusão vascular. Este estudo também destaca um possível aumento de profissionais não habilitados realizando este procedimento. Apesar do contínuo desenvolvimento dos preenchedores dérmicos e aprimoramento das opções de tratamento disponíveis, mais estudos e estratégias são necessários para reduzir a incidência de complicações e minimizar suas consequências.

RESUMO

PURPOSE: Radioiodine therapy, a standard treatment for differentiated thyroid carcinomas, is associated with several adverse events including lacrimal drainage system obstruction. Herein, we describe the first case of duct lumen recanalization using dacryoendoscopy for lacrimal passage obstruction and stenosis after radioiodine therapy. OBSERVATIONS: A 48-year-old female treated with radioiodine therapy for differentiated thyroid carcinoma 5 years prior presented with epiphora in both eyes. Dacryocystography showed nasolacrimal duct stenosis in the right eye and nasolacrimal duct obstruction in the left eye. Dacryoendoscopic examination revealed right common canalicular polyps, fibrosis in the right lacrimal sac, right nasolacrimal duct stenosis, and left upper and common canaliculus stenosis. Lacrimal passage recanalization with the insertion of a nasolacrimal stent tube using dacryoendoscopy was performed on the right eye. This successfully resolved the epiphora. CONCLUSIONS AND IMPORTANCE: Dacryoendoscopic examination for epiphora after radioiodine therapy may help detect early-stage nasolacrimal passage obstruction/stenosis. This condition can be resolved by recanalization and insertion of a lacrimal tube, without the need for a more invasive surgical approach such as dacryocystorhinostomy.

RESUMO

BACKGROUND: Estimating the volume of fat to be resected during lower lid blepharoplasty can be challenging. While the excess fat is clearly visible in the upright position, it retracts into the orbital cavity when the patient is in decubitus. Several tools have been developed to predict the volume required for adequate outcomes and to reduce the risk of complications. Among these, 3D photography, in addition to being noninvasive, radiation-free, portable and relatively inexpensive, can be used to make simulations. OBJECTIVE: To assess the level of agreement between Vectra H1 camera simulations and the outcome of lower eyelid blepharoplasties with volume removal based on these simulations. METHODS: Preoperatively, a 3D camera and simulation software (Vectra H1, Canfield Imaging Systems) was used to estimate the fat pad volume to be resected from the lower eyelids in a sample of 35 patients (female n = 34) aged 55 years on average. Following the procedure, the patients were photographed at 1, 3 and 6 months and the outcome was compared to the simulation. RESULTS: The agreement between the simulated volume and the intraoperative volume was high. While the difference between the postoperative volume and the simulated volume decreased over time, at 6 months the actual volume was still 0.30 mL (right eye) and 0.24 mL (left eye) larger than the simulated volume. CONCLUSIONS: A systematic and significant difference was found between the simulation volume and the postoperative volume. The low level of agreement observed suggests that the accuracy of the tested software is insufficient for reliable simulations.

RESUMO

BACKGROUND: Currently, botulinum toxin (BoNT) injections are the most commonly performed non-invasive procedure for rejuvenation on the upper face. The therapeutic use of botulinum toxin has generally been safe and well tolerated. Adverse effects are considered mild, transient, and self-limited. However, as with all other injectable procedures, this one is also susceptible to adverse events and complications. When the safety zones are respected, the chance of any of these complications is practically null. Thus, this review aims to describe the main complications of treatment with BoNT on the upper face and to present a practical guide based on current evidence on how to avoid them. METHODS: The literature research considered published journal articles (clinical trials or scientific reviews). Studies were identified by searching electronic databases (MEDLINE and PubMed) and reference lists of respective articles. RESULTS: The main complications secondary to BoNT injections on the upper face are: ptosis of eyelid or eyebrow, eyebrow asymmetry, diplopia, Lakeophthalmos, Palpebral ectropion, and prominence of the palpebral bags. To avoid such complications, it is necessary to have knowledge of the anatomy of this region and adequate and individualized planning based on the existing patterns of the frontalis muscle, glabella, and crow's feet. This review presents the specificities of each of these regions and practical suggestions to obtain satisfactory results, avoiding complications. CONCLUSION: Particularly on the upper face treatment with BoNT offers predictable results, has few adverse effects, and is associated with high patient satisfaction. However, it is suggested that the commented parameters and safety areas be incorporated into daily practice so that the possibilities of complications are minimized as much as possible. LEVEL OF EVIDENCE III: This journal requires that authors assign a level of evidence to each article.

RESUMO

RESUMO A obstrução de via lacrimal é uma possível complicação decorrente de tratamentos oncológicos sistêmicos e locais. A epífora crônica gera grande impacto na qualidade de vida desses pacientes, e, como a fibrose terminal da via lacrimal pode necessitar de procedimentos complexos para sua resolução, é importante estarmos atentos a esse efeito adverso, com o objetivo de reconhecê-lo e tratá-lo precocemente, ou mesmo preveni-lo. Nesta revisão da literatura, os autores analisam todos os agentes quimioterápicos e radioterápicos associados à obstrução lacrimal e descrevem os mecanismos, a frequência, os tratamentos e a profilaxia. Os tratamentos oncológicos associados à obstrução lacrimal foram: radioterapia em cabeça e pescoço (dosagem acima de 45 a 75Gy), radioiodoterapia (dosagem acima de 150mCi) e quimioterapia com 5-FU, S-1, capecitabine e docetaxel. A obstrução lacrimal pode ser irreversível, e a intubação profilática das vias lacrimais é uma possibilidade descrita de tratamento profilático em casos de radioterapia e uso do 5-FU, S-1 e docetaxel. O tratamento cirúrgico de todos os casos é a dacriocistorrinostomia.


ABSTRACT Lacrimal duct obstruction can be a side effect of systemic and/or local cancer treatments. Chronic epiphora has a great impact on the quality of life of oncological patients. Since terminal fibrosis of the lacrimal system may require complex procedures, it is important to be aware of this adverse effect in order to recognize and treat it, or even prevent it. A literature review was performed to identify all types of systemic cancer treatment associated with lacrimal obstruction and to describe the mechanisms, frequency, treatment, and prophylaxis. The oncological treatments associated with lacrimal obstruction were head and neck radiotherapy (dosage above 45-75 Gy), radioiodine therapy (dosage above 150 mCi), and chemotherapy with 5-FU, S-1, Capecitabine and Docetaxel. Depending on the dose, this complication may be irreversible. Prophylactic intubation of the lacrimal system is an option for prophylaxis in cases of radiotherapy, use of 5-FU, S-1, and Docetaxel. Final surgical treatment is dacryocystorhinostomy.

RESUMO

ABSTRACT In the literature, there is a confusing classification among congenital floppy eyelid, eyelid eversion and ectropion. They are described as eyelid malposition with laxity and out-turning of the eyelids in newborns, usually associated with conjunctival prolapse and chemosis. Although the underlying pathophysiology of these rare conditions is obscure, they share anatomic characteristics. Thus, instead of a plethora of denominations, a spectrum approach should join these entities. In this paper, the authors present a case series of four patients that illustrates distinctive presentations of this condition and advocate that it should be considered as variants of a spectrum of congenital ectropion. Mild cases, when promptly treated, can benefit from clinical treatment. On the other hand, severe and delayed cases will need surgical correction as in the case of acquired ectropion.


RESUMO Na literatura, existe uma classificação confusa entre floppy eyelid congênita, eversão palpebral e ectrópio congênito. Essas afecções são similarmente descritas como pálpebras frouxas e evertidas em recém-nascidos e geralmente associadas a prolapso de conjuntiva e quemose. Embora a fisiopatologia dessas raras afecções seja incerta, elas apresentam íntimas características anatômicas em comum. Assim, ao invés dessa nomenclatura variada, seria interessante incluí-las em um espectro de uma só doença. Neste artigo. apresenta-se uma série de quatro casos que ilustram diferentes apresentações dessa afecção e propõe-se que todas devam ser consideradas variações do espectro de ectrópio congênito. Casos leves são beneficiados quando tratados precocemente. Por outro lado, casos mais graves ou que são tratados tardiamente necessitarão de procedimento cirúrgico semelhante ao ectrópio adquirido.

RESUMO

ABSTRACT Objective: To evaluate the efficacy of mitomycin C in anatomical and functional success after modified transcanalicular diode laser dacryocystorhinostomy. Methods: A prospective, double-blinded, randomized placebo-controlled study compared the effect of topical mitomycin C on modified transcanalicular diode laser dacryocystorhinostomy. Group 1 had modified transcanalicular diode laser dacryocystorhinostomy with topical saline, while Group 2 had modified transcanalicular diode laser dacryocystorhinostomy with topical mitomycin C. Success was defined as anatomical patency and relief of symptoms at the end of 6 months. Results: Six months after surgery, Group 1 (30 patients) showed anatomical and functional success rates of 86.7% and 83.3%, respectively. Group 2 (32 patients) showed anatomical and functional success rates of 87.5% and 84.3%, respectively. There was no statistically significant difference between the groups 1 and 2 (p = 1.000). Conclusion: The use of mitomycin C did not improve the anatomical and functional success rates of modified transcanalicular diode laser dacryocystorhinostomy compared to placebo.


RESUMO Objetivo: Avaliar a eficácia da mitomicina C no sucesso anatômico e funcional após dacriocistorrinostomia transcanalicular com laser de diodo. Métodos: Estudo prospectivo, duplo-cego, randomizado e controlado por placebo. Comparou o efeito da mitomicina C tópica na dacriocistorrinostomia transcanalicular com laser de diodo. No Grupo 1, foi utilizada apenas solução salina tópica, enquanto no Grupo 2 foi utilizada mitomicina C tópica. O sucesso foi definido como permeabilidade da via lacrimal e alívio dos sintomas ao final de 6 meses. Resultados: Seis meses após a cirurgia, o Grupo 1 (30 pacientes) apresentou taxas de sucesso anatômico e funcional de 86,7% e 83,3%, respectivamente. O Grupo 2 (32 pacientes) apresentou taxas de sucesso anatômico e funcional de 87,5% e 84,3%, respectivamente. Não houve diferença estatística significante entre os Grupos 1 e 2 (p=1,000). Conclusão: O uso de mitomicina C não melhora as taxas de sucesso anatômico e funcional do dacriocistorrinostomia transcanalicular com laser de diodo em comparação ao placebo.

RESUMO

RESUMO Objetivo: O presente trabalho teve por objetivo caracterizar o perfil epidemiológico e clínico de pacientes com lagoftalmo associado à hanseníase, atendidos no ambulatório de oftalmologia da Fundação Alfredo da Matta, Manaus, Amazonas. Métodos: Trata-se de estudo retrospectivo realizado por meio da análise dos prontuários clínicos dos pacientes incluídos no estudo. Sexo, idade, forma clínica, grau de incapacidade no diagnóstico e desfecho foram obtidos dos prontuários. Início, tipo de comprometimento (unilateral ou bilateral), grau de intensidade do lagoftalmo e alterações oculares associadas também foram compilados. Resultados: Foram incluídos 65 pacientes; 66,1% eram do sexo masculino e 53,8% tinham idade superior a 60 anos. Em relação à classificação operacional da hanseníase, a maioria dos pacientes (81,5%) era multibacilar: 33,8% na forma de hanseníase borderline e 47% virchowiana. 36,9% casos apresentavam sequelas oculares associadas ao lagoftalmo: opacidade corneana, epífora, ceratopatia em faixa, e neovascularização corneana.41,6% evoluíram para a cegueira. O lagoftalmo foi conduzido de forma clínica em 23 pacientes e a abordagem cirúrgica foi indicada em 42. Em relação ao tratamento cirúrgico consistiu principalmente no implante de peso de ouro e na cantoplastia de Tessier. Discussão: O lagoftalmo nessa casuística acometeu mais homens idosos, esteve relacionado à forma multibacilar, com hanseníase do tipo virchowiano como relatado na literatura. O diagnóstico de lagoftalmo foi tardio na maioria dos casos, explicando o grande número de sequelas incluindo a cegueira. Conclusão: O presente estudo reforça a necessidade de acompanhamento oftalmológico precoce para que as potenciais e graves sequelas associadas a essa condição sejam evitadas.

Methods: This is a retrospective study carried out by analyzing the medical records of the patients included in the study. Sex, age, clinical form, degree of disability in diagnosis and outcome were obtained from medical records. Onset, type of impairment (unilateral or bilateral), degree of intensity of lagophthalmos and associated eye changes were also compiled. Results: 65 patients were included; 66.1% were male and 53.8% were older than 60 years. Regarding the operational classification of leprosy, most patients (81.5%) were multibacillary: 33.8% in the form of borderline leprosy and 47% virchowian. 36.9% of cases had ocular sequelae associated with lagophthalmos: corneal opacity, epiphora, band keratopathy, and corneal neovascularization.41.6% progressed to blindness. Lagophthalmos was performed clinically in 23 patients and the surgical approach was indicated in 42. Regarding surgical treatment, it consisted mainly of gold weight implantation and Tessier's canthoplasty. Discussion: Lagophthalmos in this sample affected more elderly men, was related to the multibacillary form, with leprosy-like leprosy as reported in the literature. The diagnosis of lagophthalmos was delayed in most cases, explaining the large number of sequelae including blindness. Conclusion: The present study reinforces the need for early eye care so that the potential and serious sequelae associated with this condition are avoided.

RESUMO

PURPOSE: To compare the accuracy and positive predictive values of the air bubble test (ABT) and endoscopic Jones I test for assessment of anatomical and functional success after diode laser transcanalicular dacryocystorhinostomy (T-DCR). METHODS: This cross-sectional study included 60 eyes of 56 patients who underwent T-DCR by a single surgical team from January 2016 to December 2018. All the 56 patients (60 eyes) underwent lacrimal syringing, endoscopic Jones I test, and ABT. Anatomical success was considered as a free passage of fluid with no reflux on the irrigation test. Functional success was defined as the resolution or improvement of epiphora (Munk score of 0 or 1). The results of irrigation test, endoscopic Jones I test, and ABT were used to calculate the accuracy and positive predictive values (PPVs) of ABT and endoscopic Jones I test for assessment of anatomical and functional success (Munk score of 0 or 1) after T-DCR. A value of p < 0.05 was considered statistically significant. All statistical evaluations were performed using SPSS software. RESULTS: There were 60 T-DCR procedures in 56 patients (82.1% women; 46 patients) with a mean age of 56.4 years (standard deviation: 15.7; range from 29 to 92). The mean follow up was 8.1 months. Overall anatomical and functional success rates were 83.3% (50/60) and 73.3% (44/60), respectively. The PPV of endoscopic Jones I test in anatomical success and functional success was 100% and 88%, respectively. The accuracy of this test in anatomical and functional success was 100% and 81.25%, respectively. The PPV of ABT in anatomical success and functional success was 100% and 90.4%, respectively. The accuracy of this test in anatomical and functional success was 92% and 80.65%, respectively. CONCLUSIONS: In conclusion, both endoscopic Jones I test and ABT showed PPV of 100% to detect anatomical success after T-DCR; the endoscopic Jones I test and ABT had 88% and 90.4% of PPV on evaluation of functional success, respectively. Both tests showed good accuracy in the assessment of anatomical and functional success after T-DCR. These outcomes may indicate that ABT could substitute Jones I test on postoperative DCR assessment.

RESUMO

The ideal implant for anophthalmic socket reconstruction has yet to be developed. Biosilicate, a highly bioactive glass-ceramic, has been used in the composition of conical implants, which were initially tested in rabbit orbits with excellent results. However, the use of this material and the conical shape of the implants require further study in the human anophthalmic socket. Thus, we propose the use of a new conical implant composed of Biosilicate for orbital volume augmentation in anophthalmic sockets. This prospective, randomized study included 45 patients receiving conical implants composed of either Biosilicate or polymethylmethacrylate (control). Patients were evaluated clinically before and 7, 30, 60, 120, and 180 days after implantation. Systemic evaluations, laboratory tests, and computed tomography of the orbits were performed preoperatively and 180 days postoperatively. Both groups had good outcomes with no significant infectious or inflammatory processes. Only 1 patient, in the Biosilicate group, had early implant extrusion. Laboratory tests were normal in both groups. Computed tomography scans showed that the implants in both groups were well positioned. The new conical implant composed of Biosilicate was successfully used for anophthalmic socket reconstruction. This implant may provide a good alternative to the only conical implant currently available on the market, which is composed of porous polyethylene.

RESUMO

Although squamous cell carcinomas (SCC) are the most frequent human solid tumor at many anatomic sites, the driving molecular alterations underlying their progression from precursor lesions are poorly understood, especially in the context of photodamage. Therefore, we used high-depth, targeted next-generation sequencing (NGS) of RNA and DNA from routine tissue samples to characterize the progression of both well- (cutaneous) and poorly (ocular) studied SCCs. We assessed 56 formalin-fixed paraffin-embedded (FFPE) cutaneous lesions (n = 8 actinic keratosis, n = 30 carcinoma in situ [CIS], n = 18 invasive) and 43 FFPE ocular surface lesions (n = 2 conjunctival/corneal intraepithelial neoplasia, n = 20 CIS, n = 21 invasive), from institutions in the US and Brazil. An additional seven cases of advanced cutaneous SCC were profiled by hybrid capture-based NGS of >1500 genes. The cutaneous and ocular squamous neoplasms displayed a predominance of UV-signature mutations. Precursor lesions had highly similar somatic genomic landscapes to SCCs, including chromosomal gains of 3q involving SOX2, and highly recurrent mutations and/or loss of heterozygosity events affecting tumor suppressors TP53 and CDKN2A. Additionally, we identify a novel molecular subclass of CIS with RB1 mutations. Among TP53 wild-type tumors, human papillomavirus transcript was detected in one matched pair of cutaneous CIS and SCC. Amplicon-based whole-transcriptome sequencing of select 20 cutaneous lesions demonstrated significant upregulation of pro-invasion genes in cutaneous SCCs relative to precursors, including MMP1, MMP3, MMP9, LAMC2, LGALS1, and TNFRSF12A. Together, ocular and cutaneous squamous neoplasms demonstrate similar alterations, supporting a common model for neoplasia in UV-exposed epithelia. Treatment modalities useful for cutaneous SCC may also be effective in ocular SCC given the genetic similarity between these tumor types. Importantly, in both systems, precursor lesions possess the full complement of major genetic changes seen in SCC, supporting non-genetic drivers of invasiveness.

RESUMO

Resumo O carcinoma de glândulas sebáceas (CGS) é a terceira neoplasia maligna mais frequente nas pálpebras. Acomete geralmente mulheres idosas e pode simular blefarite ou calázio. A reconstrução da pálpebra superior é sempre desafiadora. O objetivo deste é relatar um caso inusitado de CGS na pálpebra superior de indivíduo jovem e do sexo masculino. Foi realizada a ressecção total da pálpebra superior direita e o exame histológico revelou margens livres. A reconstrução foi feita com dois procedimentos cirúrgicos em tempos diferentes. Devido ao fato do CGS apresentar alto potencial de metástases, o paciente continua em acompanhamento para reavaliação funcional e estética.


Abstract Sebaceous gland carcinoma (SGC) is the third most frequent malignant neoplasm in the eyelids. It usually affects elderly women and can simulate blepharitis or chalazion. Upper eyelid reconstruction is always challenging. The purpose of this is to report an unusual case of SGC in the upper eyelid of a young and male patient. Total resection of the right upper eyelid was performed and histological examination revealed free margins. The reconstruction was done with two surgical procedures at different times. Due to the fact that SGC presents a high potential for metastasis, the patient continues to be followed for functional and aesthetic reevaluation.

RESUMO

ABSTRACT Purpose: To determine the reliability of the endoscopic dye transit test for the prediction of functional success after dacryocystorhinostomy. Methods: A cross-sectional study was conducted with 50 patients who underwent external dacryocystorhinostomy Group or transcanalicular dacryocystorhinostomy Group and had anatomically patent ducts during irrigation, with a minimum 6-month follow-up. The external dacryocystorhinostomy, defined as the time from instillation of the dye into the conjunctival sac until its flow from the rhinostomy site, was performed in all patients. Positive predictive value of the endoscopic dye transit test to assess functional success was analyzed. The cutoff point was determined using a receiver operating characteristic curve. Results: Of the 50 patients, 44 (88%) exhibited subjective improvement or complete resolution of epiphora (functional success). The best cutoff point for the endoscopic dye transit test was 60 s. Of 39 patients with endoscopic dye transit test £60 s, 38 (97.4%) exhibited functional success, demonstrating a 97.4% positive predictive value. Conclusion: The endoscopic dye transit test £60 s is a reliable tool to predict functional success and good prognosis after external or laser transcanalicular dacryocystorhinostomy.


RESUMO Objetivo: Determinar a confiabilidade do teste endoscópico do corante na predição do sucesso funcional após dacriocistorrinostomia. Métodos: Estudo transversal com 50 pacientes submetidos ao grupo de dacriocistorrinostomia externa ou grupo dacriocistorrinostomia transcanalicular e que possuíam dutos anatomicamente patentes pela irrigação, com seguimento mínimo de 6 meses. A dacriocistorrinostomia externa, definida como o tempo desde a instilação do corante no saco conjuntival até o fluxo do local da rinostomia, foi realizada em todos os pacientes. O valor preditivo positivo do teste endoscópico do corante para avaliar o sucesso funcional foi analisado. O ponto de corte foi determinado usando uma curva característica de operação do receptor. Resultados: Dos 50 pacientes, 44 (88%) apresentaram melhora subjetiva ou resolução completa da epífora (sucesso funcional). O melhor ponto de corte para o teste endoscópico do corante foi de 60 s. Dos 39 pacientes com teste endoscópico do corante £60 s, 38 (97,4%) apresentaram sucesso funcional, demonstrando um valor preditivo positivo de 97,4%. Conclusão: O teste en­doscópico do corante £60 s é uma ferramenta confiável para predizer o sucesso funcional e o bom prognóstico após dacriocistorrinostomia transcanalicular externa ou a laser.

RESUMO

Ductal cysts of the accessory lacrimal glands of Wolfring are rare clinical entities. They typically present as mobile and translucent lesions on the superior or inferior tarsal borders. Here, the authors describe a 7-year-old male child presenting with giant bilateral cysts of Wolfring. Management of such cysts is primarily surgical and the preferred route for excision is transconjunctival. To the best of the authors' knowledge, this is the first report of a bilateral Wolfring dacryops affecting a child.Cysts of the accessory lacrimal glands of Wolfring are rare clinical entities. To the authors' knowledge, here the authors describe the first report of a bilateral Wolfring dacryops affecting a child.
