Hallazgos nasosinusales por tomografía computada en dacriocistitis crónica pediátrica.

OBJECTIVE: To evaluate the preoperative tomographic characteristics of the nose and paranasal sinuses of children with chronic dacryocystitis. METHOD: Prospective, observational, cross-sectional, and descriptive study. CT scans of the paranasal sinuses of patients candidates for endoscopic dacryocystorhinostomy were evaluated for two years. Demographic characteristics, radiological findings, inflammatory processes and anatomical variants were identified using the Lund-Mackay classification. Statistic analysis. Stata 10.0, descriptive analysis, Student's t: mean difference and χ2. Logistic studies to estimate the probability between variables. RESULTS: 27 men and 11 women (n = 38) were included. Of these, 22 had unilateral and 16 bilateral nasolacrimal duct involvement. Lund-Mackay score range: 2-20. Eleven patients had associated pathology. The most affected were anterior and maxillary ethmoidal sinus (69%), osteomeatal complex (68%), posterior ethmoidal (51%). Patients with severe rhinosinusitis are 12 times more likely to develop dacryocystitis than patients with < 12 points. Men presented greater severity, affectation, and clinical repercussion. CONCLUSIONS: There is radiological rhinosinusal involvement in dacryocystitis, which must be evaluated and treated preoperatively to avoid postoperative complications or reinfections.

Once pacientes tuvieron patología asociada. Seno etmoidal anterior y maxilar más afectados (69%), complejo osteomeatal (68%), etmoidal posterior (51%). La probabilidad de que los pacientes con rinosinusitis grave puedan presentar dacriocistitis es 12 veces mayor que en los pacientes con < 12 puntos. Los hombres presentaron mayor gravedad, afectación y repercusión clínica. CONCLUSIONES: Existe afección rinosinusal radiológica en la dacriocistitis, que debe ser evaluada y tratada en el preoperatorio para evitar complicaciones o reinfecciones posquirúrgicas.

Ocular Manifestations of Sporotrichosis in a Hyperendemic Region in Brazil: Description of a Series of 120 Cases.

PURPOSE: To describe 120 cases of ocular sporotrichosis. METHODS: Review of medical records of patients with culture-proven (from eye specimen) ocular sporotrichosis, in Rio de Janeiro, from 2007 to 2017. RESULTS: Women were more affected (61.7%) and median age was 24 years. The isolated ocular form was more frequent (75.8%). Fixed cutaneous sporotrichosis was the most commonly associated form (48.3%). Hypersensitivity reactions were observed in 10% of patients. Ocular involvement was unilateral in 98.3% of the cases, and the most frequent clinical presentation was granulomatous conjunctivitis (86.7%), followed by eyelid lesion (25%). Dacryocystitis represented 7.5% of the cases, predominantly in children (55.6%). Itraconazole was the first choice treatment (95.8%). Sequelae were observed in 23 patients (22.5%), and surgical treatment was required for most of them. CONCLUSION: Ocular sporotrichosis can be considered a characteristic form of the zoonotic transmission, with high morbidity. Delay in initiating specific treatment is likely to increase the risk of progression to more severe forms of the disease, and development of ocular sequelae.

Bilateral congenital dacryocystocele complicated with acute dacryocystitis / Dacriocistocele congênita bilateral complicada com dacriocistite aguda

ABSTRACT Congenital dacryocystocele is an uncommon entity that results from a malformation of the nasolacrimal system, occurring predominantly in neonatal females. It may resolve spontaneously but can be associated with potentially serious complications as acute dacryocystitis, requiring referral to an ophthalmologist. Bilateral cases of congenital dacryocystocele are rarely reported. We present a case of acute dacryocystitis occurring in a female newborn with bilateral congenital dacryocystocele who presented with bilateral epiphora and a mass in the right medial canthus since birth. Computed tomography revealed a bilateral soft tissue lesion in the medial canthus of the ocular globe. Dacryocystocele progressed to secondary infection on the right and patient developed acute dacryocistitis. She was admitted to the hospital for intravenous antibiotic therapy followed by the nasolacrimal system probing. This case report is also important to address the management of congenital dacryocystocele, and the decision to carry out the most suitable treatment, considering the diverse therapeutic options.

RESUMO A dacriocistocele congênita é uma entidade incomum, que resulta de uma malformação do sistema nasolacrimal, ocorrendo predominantemente em recém-nascidos do sexo feminino. Pode se resolver espontaneamente, mas também pode estar associada a complicações potencialmente graves, como dacriocistite aguda, necessitando de encaminhamento a um oftalmologista. Raramente são relatados casos bilaterais de dacriocistocele congênita. Relatamos um caso de dacriocistite aguda acometendo um recém-nascido do sexo feminino. Ele apresentava dacriocistocele congênita bilateral, que apresentava epífora bilateral e uma massa no canto medial direito desde o nascimento. A tomografia computadorizada revelou lesão bilateral de partes moles no canto medial do globo. A dacriocistocele apresentou infecção secundária à direita, e a paciente desenvolveu dacriocistite aguda. Ela foi internada no hospital para antibioticoterapia intravenosa seguida de sondagem do sistema nasolacrimal. Este relato de caso também é importante para abordar o manejo da dacriocistocele congênita e a decisão de realizar o tratamento mais adequado, considerando as diversas opções terapêuticas.

Linfoma ocular primario vs celulitis orbitaria en tiempos de COVID-19 / Primary ocular lymphoma vs orbital cellulitis in times of COVID-19

Los tumores sólidos neoplásicos de tejido linfoide se caracterizan por proliferación acelerada de la porción linforreticular del sistema retículo endotelial, su incidencia mundial es de 4/100,000 prevalente en féminas entre 50-70 años, de etiología desconocida, asociado a helicobacter pylori, epstein barr y VIH. Clínicamente están presentes los síntomas B: fiebre, sudoraciones nocturnas, pérdida de peso, prurito y astenia. ausentes en el caso que nos ocupa de una paciente femenina de 46 años de edad que acudió a consulta de oftalmología por aumento de volumen a nivel de anejos de ojo izquierdo, proptosis indolora y disminución de la visión, con diagnóstico inicial de celulitis orbitaria tratada ambulatoriamente sin resolución. Se administró antibioticoterapia intravenosa sin mejoría clínica, se realizaron estudios complementarios de imagen radiológica, ultrasonido, resonancia magnética con evidencia de imagen tumoral de crecimiento antero lateral, desplazamiento de globo ocular, diámetro mayor de 57,3 mm, de características isointensas heterogéneas, secuencia T1 y flair, erosión de pared interna de orbita y la biopsia excisional informó linfoma primario de anexo ocular orbitario tipo no-Hodgkin. El abordaje acucioso con estudios complementarios para descartar neoplasias orbitarias en pacientes con celulitis orbitaria o dacriocistitis de evolución tórpida es necesario en todo momento, independiente de las condiciones atípicas de pandemia por COVID-19 que dificultan su manejo(AU)

Solid neoplastic tumors of lymphoid tissue are characterized by accelerated proliferation of the lymphoreticular portion of the reticulum endothelial system, their worldwide incidence is 4/100,000 prevalent in females between 50-70 years of age, of unknown etiology, associated with helicobacter pylori, epstein barr and HIV. Clinically, symptoms B are present: fever, night sweats, weight loss, itching and asthenia, absent in the present case of a 46-year-old female patient who came to the ophthalmology office due to increased volume at the level of the appendages. of the left eye, painless proptosis and decreased vision, with an initial diagnosis of orbital cellulitis treated outpatiently without resolution. Intravenous antibiotic therapy was administered without clinical improvement, complementary radiological imaging studies, ultrasound, magnetic resonance imaging were performed with evidence of an anterolateral growth tumor image, ocular globe displacement, diameter greater than 57.3 mm, heterogeneous isointense characteristics, T1 sequence and flair, erosion of the internal wall of the orbit and the excisional biopsy reported primary non-Hodgkin type orbital annex lymphoma. A careful approach with complementary studies to rule out orbital neoplasms in patients with orbital cellulitis or dacryocystitis of torpid evolution is necessary at all times, regardless of the atypical conditions of a COVID-19 pandemic that make its management difficult(AU)

Acute dacryocystitis retention: a case report and literature review / Dacriocistite aguda de retenção: relato de caso e revisão da literatura

ABSTRACT Acute dacryocystitis retention (ADR) is an unusual entity that contributes to an incorrect diagnosis and treatment. We describe a case of acute dacryocystitis retention occurring in a 61-year-old diabetic male who presented with severe pain, swelling, and inflammatory signs above the left medial canthal ligament tendon. He had no previous history of epiphora. Computed tomography scan indicated acute dacryocystitis. Clinical treatment resulted in complete resolution of the condition. Syringing one month after the acute episode indicated a patent lacrimal excretory system. The temporary obstruction that evolved to an acute dacryocystitis retention was probably secondary to nasal alteration or supposed dacryoliths. Timely, conservative clinical treatment can lead to complete resolution of acute dacryocystitis retention with no further treatments.

RESUMO A dacriocistite aguda de retenção é uma entidade incomum, o que contribui para que o diagnóstico e o tratamento não sejam corretos. Estamos descrevendo um caso de dacriocistite aguda de retenção ocorrendo em um homem diabético de 61 anos que apresentou dor intensa, edema e sinais inflamatórios acima do tendão cantal medial esquerdo. Ele não tinha histórico anterior de epífora. A tomografia computadorizada indicou dacriocistite aguda. O tratamento clínico resultou na resolução completa da condição. A irrigação, um mês após o episódio agudo, indicou sistema excretor lacrimal pérvio. A obstrução temporária que evoluiu para uma dacriocistite aguda de retenção foi provavelmente secundária a alteração nasal ou supostos dacriolitos. O tratamento clínico conservador pode levar à resolução completa da dacriocistite aguda de retenção, sem necessidade de outros tratamentos.

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.

Nasolacrimal obstruction concomitant to cataract: diagnosis and management in the preoperative period of cataract surgery / Obstrução lácrimo-nasal concomitante a catarata - diagnóstico e conduta no período pré-operatório da facectomia

ABSTRACT Purpose: Concomitant nasolacrimal duct obstruction can occur in cataract carriers, which increases the risk of postoperative endophthalmitis. The primary aim of this study is to evaluate the knowledge of Brazilian cataract surgeons on the diagnosis and management of cataracts associated with nasolacrimal duct obstruction. Methods: This survey was based on a questionnaire involving Brazilian cataract surgeons that was conducted from March to April 2018. Data were collected on the participant's profile, time and experience in ophthalmic practice, previous training in diagnosis and management of nasolacrimal duct obstruction, and background with endophthalmitis after cataract surgery in patients with nasolacrimal duct obstruction. All data were entered into an Excel spreadsheet and analyzed according to the frequency of occurrence. Results: Ninety-one ophthalmologists answered the questionnaire. Most (63.7%) had been performing cataract surgery for >10 years, and most (84.6%) received training to diagnose and handle nasolacrimal duct obstruction during their medical residence training. Nasolacrimal duct obstruction was investigated in the preoperative period of the cataract by lacrimal sac expression test (53.8%) or by irrigation of the tear pathways (23.1%). Nasolacrimal duct obstruction was treated with antibiotic eye drops by 47.2% of respondents. Seventy-eight percent of surgeons indicate usually performing lacrimal surgery prior to the intraocular surgery, waiting for 4 to 6 weeks to proceed with the cataract surgery. The procedure of choice for treating nasolacrimal duct obstruction prior to cataract surgery was dacryocystorhinostomy (88.4%). Most participants recognized the need for a protocol to assist in the detection and management of nasolacrimal duct obstruction in cataract carriers. Conclusion: Improvement in the diagnosis and management of nasolacrimal duct obstruction concomitant to cataract is needed, as this is a risk factor for endophthalmitis.

RESUMO Objetivo: Portadores de catarata podem apresentar concomitantemente obstrução do ducto lacrimo-nasal (DLN), com risco de desenvolver endoftalmite no pós-operatório da facectomia. O objetivo do presente estudo é apresentar as percepções dos cirurgiões de catarata sobre a propedêutica e a conduta frente a pacientes com obstrução do ducto lacrimo-nasal concomitante com catarata. Métodos: Trata-se de uma pesquisa baseada em um questionário envolvendo cirurgiões brasileiros de catarata, realizado no período de março a abril de 2018. Foram levantados dados sobre o perfil dos participantes, o tempo e a experiencia da prática oftalmológica, o treinamento prévio para diagnóstico e tratamento da obstrução do ducto lacrimo-nasal e os conhecimentos de endoftalmite após cirurgia de catarata. Todos os dados foram inseridos em planilha Excel e analisados de acordo com a frequência de ocorrência. Resultados: Noventa e um oftalmologistas responderam ao questionário. A maioria (63,7%) deles realiza cirurgias de catarata há mais de 10 anos e a maioria (84,6%) recebeu treinamento para diagnóstico e tratamento da obstrução do ducto lacrimo-nasal durante o curso de residência médica. A pesquisa da obstrução crônica do ducto lacrimo-nasal no pré-operatório da catarata é feita pelo teste do refluxo de secreção pelos pontos lacrimais (53,8%) ou por irrigação das vias lacrimais (23,1%). A obstrução do ducto lacrimo-nasal é tratada com colírios antibióticos por 47,2% dos respondentes. Para os portadores de obstrução do ducto lacrimo-nasal , 78% indicam a desobstrução das vias lacrimais previamente à facectoma, aguardando de 4 a 6 semanas para tal. O procedimento de escolha para tratar a obstrução do ducto lacrimo-nasal antes da facectomia é a dacriocistorrinostomia (88,4%). A necessidade de um protocolo para auxiliar na detecção e tratamento da obstrução do ducto lacrimo-nasal em portadores de catarata é reconhecida pela maioria dos participantes deste estudo. Conclusão: É necessário melhorar a propedêutica e o manejo da catarata em portador de obstrução do ducto lacrimo-nasal porque esse é um fator de risco para endoftalmite.

Dacrioestenosis con dacriocistitis aguda en lactante, a propósito de un caso / Dacryostenosis with acute dacryocistitis in an infant, a case report

RESUMEN La obstrucción del conducto nasolacrimal (OCNL) o dacrioestenosis consiste en una canalización incompleta de dicho conducto. El cuadro clínico se presentó a las 2-6 semanas de edad y se caracteriza por epifora y secreción mucopurulenta. Genera diversas complicaciones, como la dacriocistitis aguda, una inflamación supurativa caracterizada por dolor, eritema e hinchazón; que puede evolucionar a un absceso lagrimal, celulitis preseptal y puede complicarse a celulitis orbitaria, absceso orbitario, trombosis del seno cavernoso, trombosis de la vena oftálmica superior y meningitis. Se presenta el caso de un lactante de siete meses 28 días de vida extrauterina con antecedente de prematuridad, diagnóstico de Tetralogía de Fallot y dacrioestenosis en ojo derecho. A su ingreso a emergencia, se evidenció eritema, aumento de calor local, secreción sero-amarillenta, consistencia dura con dolor a la palpación y edema periorbitario derecho. Clínicamente se concluyó en el diagnóstico de dacriocistitis aguda.

SUMMARY The obstruction of the nasolacrimal conduct or dacryostenosis is the result of an incomplete canalization of such a conduct. The clinical manifestations start 2-3 weeks after birth and are characterized by epiphora and muco-purulent discharge. Dacryostenosis may lead to several complications such as acute dacrocystitis, that is a suppurative inflammation characterized by pain, erythema and swollen that can evolve to a lacrimal abscess, pre-septal cellulitis, orbital cellulitis, orbital abscess, cavernous sinus thrombosis, thrombosis of the superior ophthalmic vein and meningitis.

Congenital dacryocystocele diagnosed by antenatal ultrasonography with spontaneous resolution / Dacriocistocele congênita diagnosticada por ultrassonografia pré-natal com resolução espontânea

ABSTRACT Dacryocystocele is a rare benign facial abnormality of the nasolacrimal system, which may be detected at the antenatal workup during the third trimester of pregnancy. Ultrasound is the method of choice for this examination. However, magnetic resonance imaging may also be used in selected cases. Dacryocystocele is mostly a transient finding; it may resolve spontaneously in utero or postnatally. When the defect is bilateral and persists in neonatal life, it may lead to respiratory complications. We report a case of a fetus with bilateral dacryocystocele diagnosed by prenatal ultrasound at the beginning of the third trimester of pregnancy with spontaneous postpartum resorption.

RESUMO A dacriocistocele é uma anormalidade facial benigna rara do sistema nasolacrimal, que pode ser detectada na rotina pré-natal durante o terceiro trimestre da gravidez. O ultrassom é o método de escolha, mas a ressonância magnética também pode ser usada em casos específicos. Na maioria das vezes, a dacriocistocele é um achado temporário, que pode se resolver espontâneamente ainda no útero ou após o nascimento. Quando a anormalidade é bilateral e persiste na vida neonatal, pode levar a complicações respiratórias. Este é o relato do caso de um feto com dacriocistocele bilateral diagnosticada por ultrassom pré-natal no início do terceiro trimestre da gravidez, com reabsorção espontânea após o nascimento.

Valor del ultrasonido en el diagnóstico de los tumores del saco lagrimal / Value of the ultrasound in the diagnosis of lacrimal sac tumor

RESUMEN Los tumores del saco lagrimal son extremadamente raros, y el benigno primario más común es el papiloma escamoso. Clínicamente se manifiestan como una zona de tumefacción en la región cantal medial, asociado a epifora y dacriocistitis crónica-recurrente. Dentro de las pruebas de imagen recomendadas están: dacriocistografía, tomografía computarizada, resonancia magnética y dacrioescintifotografía. Sin embargo, muy pocos sugieren el uso del ultrasonido. Se presenta el caso de un papiloma mixto del saco lagrimal diagnosticado por ultrasonido. Se trata de una paciente femenina de 39 años, quien fue remitida por cuadros repetidos de dacriocistitis derecha en los últimos 3 años. En consulta se constató celulitis preseptal ipsolateral, por lo que se indicó antibiótico-terapia, y se logró la remisión de los signos inflamatorios agudos, pero persistió el aumento del volumen cantal medial derecho. La vía lagrimal se exploró y se comprobó que estaba obstruida. Se realizó ultrasonido, donde el saco lagrimal derecho apareció ocupado por una masa ecogénica, que se extendía al conducto lacrimonasal y mostraba ligera vascularidad. Seguidamente se hizo tomografía computarizada, y se confirmaron los hallazgos ecográficos, pero sin lograr delimitar la lesión intrasaco descrita, aún tras la administración de contraste yodado endovenoso. Se sugirió dacriocistitis crónica derecha, secundaria al tumor intrasaco de aspecto benigno, probable papiloma, por lo que se efectuó cirugía y examen histopatológico que ratificaron dicho diagnóstico. En conclusión, el ultrasonido del saco lagrimal es un método complementario de gran valor, que en algunos casos hará el diagnóstico, y en otros brindará información que optimizará la decisión de quienes serían tributarios a estudios más complejos(AU)

ABSTRACT Lacrimal sac tumors are extremely rare, and the most common benign primary is squamous papilloma. Clinically, they manifest as a zone of swelling in the medial canthal region, associated with epiphora and chronic-recurrent dacryocystitis. Among the recommended imaging tests are dacryostography, computed tomography, magnetic resonance imaging, and dacryoscintifotography. However, very few suggest the use of ultrasound. The case of a mixed papilloma of the lacrimal sac diagnosed by ultrasound is presented. This is a 39-year-old female patient, who was referred for repeated cases of right dacryocystitis in the last three years. In consultation, ipsolateral preseptal cellulitis was found, for which antibiotic therapy was indicated, and the remission of acute inflammatory signs was achieved, but the increase in right medial canthal volume persisted. The lacrimal duct was explored and found to be obstructed. Ultrasound was performed, where the right lacrimal sac appeared occupied by an echogenic mass, which extended to the lacrimal duct and showed slight vascularity. Subsequently, computed tomography was performed, and the ultrasound findings were confirmed, but without defining the described intrasaccal lesion, even after administration of intravenous iodinated contrast. It was suggested chronic right dacryocystitis, secondary to apparently benign intrasaccal tumor, probable papilloma, so surgery and histopathological examination were performed, which that ratified the diagnosis. In conclusion, ultrasound of the lacrimal sac is a complementary method of great value, which in some cases will make the diagnosis, while in others it will provide information that will optimize the decision of those who would be candidate to more complex studies(AU)

Bilateral Simultaneous Endoscopic Dacryocystorhinostomy: Outcome and Impact on the Quality of Life of the Patients.

Introduction Bilateral simultaneous endoscopic dacryocystorhinostomy (endo-DCR) has received little attention in the literature, thus many surgeons continue to address bilateral nasolacrimal duct obstruction at two stages, rather than in the same setting. Objective To evaluate the feasibility and the outcome of simultaneous bilateral Endo-DCR and its impact on the quality of life of the patients. Methods We have conducted a retrospective analysis of patients who underwent bilateral simultaneous endo-DCR between March 2013 and February 2017 at our tertiary care institution. The reviewed data included clinical presentation; operative details; success rate; pre and postoperative evaluation of the symptoms of the patients, using the Nasolacrimal Duct Obstruction Symptom Score Questionnaire; satisfaction of the patients, and improvement in the quality of life, assessed by the Glasgow Benefit Inventory (GBI) questionnaire. Results Out of 128 cases in which endo-DCRs were performed, 13 were bilateral (26 sides). Postoperative success was documented in 24 of the 26 sides (92.3%), with a mean follow-up duration of 16.2 months. The two failed sides were reported in the same case. The preoperative symptom score ranged between 12 and 80 (mean ± standard deviation [SD]: 38.23 ± 15.7). The postoperative symptom score was significantly lower (mean ± SD: 5.4 ± 12.9). The success rates in unilateral and bilateral cases were comparable, with no statistically significant difference. A notable improvement in the quality of life of the patients was also reported, with a mean GBI score of 81.38 ± 12.37. Conclusion Our results support that a simultaneous bilateral endo-DCR is a safe procedure that offers a high success rate, spares the patient from the stress of a second surgery, provides the patient with a bilateral resolution of the symptoms, and confers an immediate improvement in the quality of life of the patients.

Esporotricose ocular: manifestações atípicas / Ocular sporotrichosis: atypical manifestations

Resumo A esporotricose humana e animal é uma infecção subaguda a crônica causada pelo fungo dimórfico Sporothrix schenckii. A esporotricose ocular tem ganhado destaque em função da epidemia de esporotricose urbana enfrentada pelo estado do Rio de Janeiro na última década e se apresenta classicamente como conjuntivite granulomatosa, mas formas atípicas podem ocorrer. Este artigo tem por objetivo relatar 2 casos atípicos de esporotricose ocular em pacientes imunocompetentes, ambos apresentando quadro clínico compatível com a síndrome oculoglandular de Parinaud associada à dacriocistite em um caso e presumivelmente à coroidite no outro caso.

Abstract Human and animal sporotrichosis is an infection caused by the dimorphic fungus Sporothrix schenckii, which is classified from subacute to chronic. Ocular sporotrichosis has been highlighted due to the epidemic of urban sporotrichosis faced by the state of Rio de Janeiro in the last decade and presents classically as granulomatous conjunctivitis, but atypical forms may occur. This article aims to report two atypical cases of ocular sporotrichosis in immunocompetent patients, both presenting a clinical picture compatible with Parinaud oculoglandular syndrome associated with dacryocystitis in one case and presumably to choroiditis in the other case.

Bilateral simultaneous endoscopic dacryocystorhinostomy: outcome and impact on the quality of life of the patients

Tomographic and anatomical study of the orbit and nasolacrimal duct in capybaras (Hydrochoerus hydrochaeris-Linnaeus, 1766).

The objective of this study was to describe the reference values of cranial measurements of capybaras, correlating the ocular orbit with the nasolacrimal duct. The documentation of its results can contribute to standardizing characteristics of anatomical normality and favouring the correct diagnosis and treatment of changes. The capybara carcasses, maintained by freezing, were distributed in two groups (G) designated GA (n = 12) adult animals (A) and GY (n = 13) for young animals (Y). All subjects underwent dacryocystography examination by computed tomography (CT) and cranial measurements. Descriptive analyses of cranial and nasolacrimal duct measurements and statistical analysis of the Pearson correlation with the variable weight were performed. In GA, there was no correlation between the nasolacrimal and cranial duct measurements. However, in the GY, a correlation was verified with facial length (r = .6233), facial width (r = .5771), cranial height (r = .6981), cranial length (r = .7116), total right length (r = .7517) and left length (r = .7999). Thus, in the young animals, cranial length measurements were strongly correlated with nasolacrimal duct lengths. However, this biological behaviour was not observed in adults, demonstrating stability in development. The capybara's ocular orbit was found to be circular and incomplete, with developed zygomatic process of the maxilla. CT dacryocystography is indicated to evaluate the nasolacrimal canal pathway in capybaras, emphasizing the importance of normal anatomical study to aid in treating animals affected by diseases.

Dacryocystectomy as a treatment of chronic dacryocystitis in the elderly.

To evaluate the dacryocystectomy (DCT) outcomes for chronic dacryocystitis in an elderly population over 70 years old. A retrospective chart review was performed for patients over 70 years old who were diagnosed with chronic dacryocystitis and underwent DCT at the Botucatu School of Medicine, UNESP, Brazil, from 2007 to July 2014. Data were collected about patient demographics, age, gender, previous nasal, or ophthalmic diseases, symptoms related to the lacrimal drainage system preoperatively and postoperatively, signs of enlargement of the lacrimal sac (regurgitation of secretion), and histopathologic evaluation. The study sample was comprised of 17 patients with an average age of 76.5 ± 8.5 years. The major complaint for all patients was tearing and 17.6% patients had an additional complaint of discharge. Regurgitation of secretion with lacrimal sac expression was present in 76.5% of patients. Postoperatively, 76.5% of the patients reported improvement of the initial complaint, likely due to the total excision of the lacrimal sac which removed the focal site of chronic infection. Epiphora persisted in 23.5% of patients, of whom 11.7% underwent successful lacrimal stent intubation. DCT for chronic dacryocystitis should be considered a primary procedure in individuals over 70 years old. This procedure has a much lower risk to these patients who often have associated comorbidities.

Ultrasound parameters of normal lacrimal sac and chronic dacryocystitis / Parâmetros ultrassonográficos do saco lacrimal normal e na dacriocistite crônica

ABSTRACT Purpose: To compared the ultrasound findings of the lacrimal sac between subjects with normal lacrimal systems those with chronic dacryocystitis. Methods: A retrospective study of 10 subjects with a normal lacrimal system (Group 1) and 10 with chronic dacryocystitis (Group 2) diagnosed according to B-mode ultrasound with a 10-MHz transducer and the direct-contact technique (AVISO, Quantel Medical) for lacrimal sac assessment. We analyzed the dimensions, features, and content of the sacs. Characteristics of the population: female: 6, Group 1; 8, Group 2; mean age 48.4 years (SD=19.9; range, 22-80 years), Group 1; 50.5 years (SD=15.5; range, 25-75 years), Group 2. Results: The dimensions of the lacrimal sac were as follows: anteroposterior 1.86 and 10.99 mm in Groups 1 and 2, respectively, p<0.0001; vertical 9.79 and 14.13 mm in Groups 1 and 2, respectively, p=0.049. Qualitative evaluation of the lacrimal sac contents showed hypoechogenic content in Group 1 (10, 100%) and hyperechogenic punctiform content in Group 2 (10, 100%) with partial filling in seven cases (70%). Conclusions: Ultrasonography can differentiate normal lacrimal sacs from sacs compromised by chronic dacryocystitis, thus being useful as an adjunct to clinical examination and surgical planning.

RESUMO Objetivo: Categorizar os achados ultrassonográficos do saco lacrimal em indivíduos com via lacrimal normal e em portadores de dacriocistite crônica. Métodos: Estudo retrospectivo de 20 indivíduos, 10 com via lacrimal normal (Grupo 1) e 10 com diagnóstico de dacriocistite crônica (Grupo 2) utilizando ultrassonografia modo B com transdutor de 10 MHz e técnica de contato (Aviso, Quantel Medical) para avaliar o saco lacrimal. Analisamos os seguintes parâmetros: dimensões, características e conteúdo. Resultados: Características da população estudada: sexo feminino: 6, Grupo 1; 8, Grupo 2; idade média: 48,4 anos (DP=19,93; variação, 22 a 80 anos), Grupo 1; 50,5 anos (DP=15,47; variação, 25 a 75 anos), Grupo 2. As dimensões do saco lacrimal foram aferidas: anteroposterior, 1,86 mm no Grupo 1 e 10,99 mm no Grupo 2, p<0,0001; vertical, 9,79 mm no Grupo 1 e 14,13 mm no Grupo 2, p=0,049. A avaliação qualitativa do conteúdo do saco lacrimal mostrou: conteúdo hipoecogênico no Grupo 1 (10, 100%); e conteúdo puntiforme hiperecogênico no Grupo 2 (10, 100%), com preenchimento parcial em 7 casos (70%). Conclusão: A ultrassonografia foi capaz de diferenciar a via lacrimal normal da acometida por dacriocistite crônica, e de determinar parâmetros úteis para suportar o acompanhamento clínico ou auxiliar no planejamento cirúrgico.

A comparative study of modified transcanalicular diode laser dacryocystorhinostomy versus conventional transcanalicular diode laser dacryocystorhinostomy.

External dacryocystorhinostomy (DCR) is the gold standard surgical technique for the treatment of primary acquired nasolacrimal duct obstruction (PANDO). However, new techniques such as endoscopic DCR and transcanalicular dacryocystorhinostomy (T-DCR) are being studied in an attempt to reduce surgical time, avoid external scarring and preserve the lacrimal pump while achieving the same efficacy. The purpose of this study was to compare the efficacy between conventional T-DCR and modified transcanalicular dacryocystorhinostomy (MT-DCR) in patients with PANDO. MT-DCR is performed to remove nasal mucosa prior to laser osteotomy. This is a comparative, prospective, interventionist and randomized study. Patients with PANDO were selected to undergo MT-DCR or T-DCR by blocked randomization. PANDO was diagnosed based on clinical presentation, dye disappearance test and dacryocystography. All of the procedures were performed by the same surgery team members. Anatomical success outcome was defined as positive lacrimal syringing and functional success outcome was defined as the absence or improvement of epiphora. A total of 44 surgical procedures were performed (22 MT-DCR and 22 T-DCR). In the case of MT-DCR, the anatomical and functional success rates after 12 months were 90 and 86%, respectively. After T-DCR, these rates were 77 and 72%, respectively (p = 0.162). MT-DCR and T-DCR are both safe and fast procedures with low morbidity and well-tolerated.

Dacryoliths causing intermittent epiphora associated with a patent lacrimal system / Dacriolitíase causando epífora intermitente associada a um sistema lacrimal de patente

ABSTRACT We present two patients with dacryoliths and patent lacrimal drainage with intermittent tearing and without infection. Dacryoliths can be present in the lacrimal sac or lacrimal duct without acute or chronic inflammation. In these cases, we believe dacryolith formation was a causative factor of intermittent epiphora even with a patent drainage system, and we propose that dacryoliths and even fungal colonization formation may be the first event before dacryocystitis and should be considered as a cause of epiphora.

RESUMO Apresentamos dois pacientes com dacriolitíase e drenagem lacrimal patente com lacrimejamento intermitente, sem infecção. Os dacriolitos podem estar presentes no saco lacrimal ou duto lacrimal, sem inflamação aguda ou crônica. Neste caso nós acreditamos que a dacriolitíase foi um fator causador da epífora intermitente mesmo com sistema de drenagem patente e propomos que dacriolitíase e até mesmo a colonização fúngica pode ser o primeiro evento antes dacriocistite, e deve ser adicionada como uma das causas de epífora.

Dacriocistorrinostomía externa: resultados en un año de experiencia en Villa / External dacryocystorhinostomy: outcomes achieved in one-year experience in Villa Clara province

Objetivo: describir los resultados de la cirugía dacriocistorrinostomía externa en un año. Métodos: se realizó un estudio observacional, descriptivo longitudinal prospectivo en 25 pacientes, 28 ojos. Se consideraron las variables sexo, color de piel, edad, lado afectado, etiología, complicaciones y resultados de la cirugía. Resultados: hubo 7 pacientes masculinos y 18 femeninos; de ellos, 16 blancos y 9 no blancos con una diferencia estadísticamente significativa (p= 0,043). La edad promedio fue de 69 ± 11 años. En 13 pacientes (52,0 por ciento) se afectó el lado izquierdo y en el 68,0 por ciento la etiología fue involutiva con significación estadística (p= 0,0003). El sangramiento transoperatorio se presentó como complicación en el 24,0 por ciento de los pacientes. El 92,0 por ciento refirió mejoría de la sintomatología después de operados. Según el criterio del cirujano, la mejoría objetiva se obtuvo en el 88,0 por ciento de los casos. La dacriocistorrinostomía externa fue más frecuente en mujeres blancas encontradas entre su sexta y séptima década de vida. El lado izquierdo fue el más afectado con predominio de la etiología involutiva. Las complicaciones fueron escasas; dentro de ellas predominó el sangramiento transoperatorio. Conclusiones: la mayoría de los pacientes sintieron mejoría después de la cirugía; el criterio del cirujano estuvo a favor de los resultados positivos en la cirugía dacriocistorrinostomía externa(AU)

Objective: to describe the results of external dacryocystorhinostomy surgery in one year. Methods: a prospective, longitudinal descriptive and observational study was conducted in 28 patients from 25 patients. The study variables were gender, race, age, affected side, etiology, complications and surgery outcomes. Results: there were 7 male and 18 female patients, 16 Caucasians and 9 non-Caucasians with statistically significant difference (p= 0,043). The mean age was 69 ± 11 years. The obstruction involved the left side in 13 patients (52 percent) and involution was the main etiology in 68 percent with statistical significance (p= 0,0003). Perioperative bleeding was the main complication (24 percent). In the group, 92 percent said the symptoms had reduced after surgery, and according to the surgeon, objective improvement was attained in 88 percent of cases. Conclusion: external dacryocystorhinostomy was more frequent in Caucasian women aged 60 to 70 years. The left side was the most affected, with prevailing involution etiology. There were minimum complications, being perioperative bleeding predominant. Most of the patients felt better after surgery and the surgeon´s criteria were in favor of the positive results of this surgery(AU)

Objetivo: comparar la técnica de sondaje de vías lagrimales previa dilatación canalicular con gel viscoelástico con el sondaje directo. Métodos: se realizó un estudio analítico prospectivo de cohorte no concurrente en 136 ojos pertenecientes a pacientes con obstrucción congénita del conducto lacrimonasal atendidos en la Consulta de Oftalmopediatría del Hospital Pediátrico Docente Pepe Portilla, de Pinar del Río, a quienes se les realizó sondaje de vía lagrimal, desde enero del año 2008 a julio de 2013. Se conformaron dos grupos de estudio, ambos de 68 ojos, uno con la técnica quirúrgica de sondaje directo, y un segundo grupo donde se aplicó dilatación previa de la vía excretora con gel viscoelástico. Resultados: en el primer grupo se presentaron complicaciones en el 45,59 por ciento. Se logró el 54,41 por ciento de curación y fue reintervenido el 32,35 por ciento. En el segundo grupo se logró el 97,92 por ciento de curación sin complicaciones incluyendo a 6 ojos de pacientes mayores de 3 años, y fue necesario reintervenir a un solo paciente. Conclusiones: el sondaje del conducto lacrimonasal previa dilatación con Healon minimiza las complicaciones y la necesidad de reintervención, y posibilita su empleo efectivo en pacientes mayores de 3 años(AU)

Objective: to compare the lachrymal duct probing technique after canalicular dilation canalicular with viscoelastic gel or with direct probing. Methods: prospective, analytical and non-concurrent cohort study carried out in 136 eyes from patients with congenital nasolachrymal duct obstruction, who were seen at the ophthalmological pediatric service in Pepe Portilla teaching pediatric hospital located in Pinar del Rio and who underwent lachrymal duct probing in the period of January, 2008 through July,2013. Two study groups were formed with 68 eyes each, one treated with direct probing, and the other with previous dilation of the excretory duct with viscoelastic gel. Results: the first group showed some complications in 45,59 percent of patients; 54,41 percent recovered and 32,35 percent were reoperated. In the second group, 97,92 percent managed to recover without complications, including 6 eyes from patients older than 3 years. It was necessary to re-operate a patient. Conclusions: nasolachrymal duct probing after dilation with Healon minimizes complications and need for reoperation, thus facilitating its use in patients aged over 3 years(AU)
