Lupus Vulgaris Coexisting with Sinonasal Tuberculosis and Tuberculous Dacrocystitis.

We describe the case of a 72-year-old female diabetic who presented with epiphora and purulent discharge from the right eye for the past 2 years and multiple skin lesions over the right upper eyelid and right arm for 1 year. Computed tomography of the paranasal sinuses revealed mucosal thickening in the frontal and ethmoidal sinuses, with a polypoidal mass from the right side of the nasal septum and dacrocystitis. The histopathology of the skin lesion was suggestive of lupus vulgaris (LV). There was no evidence of pulmonary tuberculosis. This case was a rare coexistence of LV with sinonasal tuberculosis and dacrocystitis.

Clinicobacteriological profile and antibiotic susceptibility pattern of chronic dacryocystitis in adults

Background: Chronic dacryocystitis is a constant menace to delicate ocular structures. If left untreated, it can lead to sight as well as life-threatening complications. However, such complications may be prevented by timely intervention along with appropriate antibiotic prophylaxis. The objectives are to investigate the current bacterial community profile in adult patients with chronic dacryocystitis attending a referral eye care center in Odisha and to determine their drug susceptibility pattern to commonly used antimicrobial agents. Materials and Methods: An observational study was conducted on 70 adult patients with chronic dacryocystitis. The discharge from the punctum was collected by doing a regurgitation test or lacrimal passage irrigation and sent for microbiological analysis. Results: Out of 70 samples collected, 54 (77.1%) samples showed bacterial growth after 24–48 h of incubation. Among various isolates recovered, 68.5% were gram-positive and 27.8% were gram-negative organisms. Staphylococcus aureus was found to be the most common isolate among gram-positive, and Pseudomonas aeruginosa was most common among gram-negative organisms. Among all drugs used in the susceptibility test; amikacin, piperacilin + tazobactam, and netilmycin were found to be most sensitive and cefixime, and amoxycilin + clavulinic acid was found to be most resistant to gram-positive as well as for gram-negative organisms. Conclusion: Knowledge about the microbiological profile and the drug susceptibility pattern responsible for chronic dacryocystitis in a geographical area is important and should be kept in mind while treating these patients.

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.

Effect of different courses of Budesonide on endoscopic dacryocystorhinostomy / 国际眼科杂志(Guoji Yanke Zazhi)

AIM: To compare the effect of different courses of budesonide nasal spray on the postoperative efficacy of endoscopic dacryocystorhinostomy.METHOD: Prospective study. A total of 90 patients(90 eyes)with chronic dacryocystitis who underwent endoscopic dacryocystorhinostomy in our hospital from January 2019 to April 2022 were selected, and they were randomly divided into three groups. In group A, 30 patients(30 eyes)continued to use budesonide nasal spray for 2mo after surgery; in group B, 30 patients(30 eyes)continued to use budesonide nasal spray for 3mo after surgery; in group C, 30 patients(30 eyes)continued to use budesonide nasal spray for 4mo after surgery. Follow-up for 6mo after surgery, Lund-Kenndey score, surgical efficacy and complications of the three groups were compared.RESULT: At 3, 4 and 6mo after surgery, the Lund-Kenndey score of group C was lower than that of group A(P<0.05), and there was no statistical difference between group C and group B(P>0.05). Following up to 6mo, the surgical efficacy of group C was better than that of group A, and the incidence of complications was lower than that of group A(P<0.05); There was no statistically significant difference in efficacy and complications between group C and group B(P>0.05).CONCLUSION: Budesonide combined with endoscopic dacryocystorhinostomy has acceptable efficacy in the treatment of chronic dacryocystitis. After 3mo of treatment, inflammation can be well controlled, which can reduce the occurrence of postoperative complications and improve the effective rate of surgery. However, increasing the treatment course cannot further improve the effective rate of surgery.

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.

@#AIM: To investigate the proportional distribution of the size of lacrimal sac in recurrent dacryocystitis after the removal of artificial nasolacrimal duct and the clinical effect of dacryocystorhinostomy under nasal endoscope on patients with recurrent dacryocystitis.METHODS: Totally 73 patients(73 eyes)with recurrent dacryocystitis after removal of artificial nasolacrimal duct in our hospital from January 2018 to November 2019 were retrospectively studied. All patients underwent dacryocystography after hospitalization, and then performed dacryocystorhinostomy combined with intubation of double- artificial nasolacrimal duct under nasal endoscope and general anesthesia. The size of lacrimal sac was measured, and the area and effective rate of fistula were analyzed respectively at 2wk, 1, 3 and 6mo after operation. RESULTS: There were 13 eyes with large dacryocyst(Transverse diameter > 5mm, 18%), 26 eyes with middle dacryocyst(Transverse diameter between 2-5mm, 36%), and 34 eyes with small dacryocyst(Transverse diameter <2mm, 47%); There was significant difference in the stoma area of dacryocystostomy at 2wk, 1, 3, 6mo respectively(<i>P</i><0.05); Compared with 2wk, 1, 3mo after operation, the stoma area at 6mo after operation significantly decreased by 14.08±0.68, 10.49±0.75, 0.31±0.23mm2(all <i>P</i><0.05); The curative rates were 100%, 93%, 88% and 85% at 2wk, 1, 3, 6mo after operation, respectively. CONCLUSION: After the removal of the artificial nasolacrimal duct, the majority of the patients with recurrent dacryocystitis typically featured medium and small lacrimal sac. The curative effect of this type of recurrent dacryocystitis by dacryocystorhinostomy and intubation under nasal endoscope was proved to be effective, which could serve as a proper and better choice in clinic practice.

Immune factors in the pathogenesis of dacryocystitis and their roles / 中华实验眼科杂志

Dacryocystitis is a common ophthalmic disease, and the main treatment of it is to abandon the obstructed nasolacrimal duct and create a new lacrimal drainage pathway through implanting a tube.For now, its pathogenesis is understood very limitedly.It is widely accepted that many factors take part in its occurrence, among which obstruction and infection play important roles.Recent researches have shown that there is lacrimal drainage-associated lymphoid tissue (LDALT) which changes remarkably in dacryocystitis, and significant differences in cytokines expression levels in tears between dacryocystitis patients and normal control have been found.In addition, the lacrimal duct has reactions similar to immune rejection to the silicone tube.All of these indicate that immune factors participate in the pathogenesis of dacryocystitis.Changes of immune tissue and macromolecular substances including the LDALT, cytokines, local tissue and cytokines after tube implantation were reviewed to analyze the changes and possible roles of immune factors in the pathogenesis of dacryocystitis.

Prognostic value of DIP endoscopic scoring system for simultaneous operation in patients with chronic dacryocystitis complicated with sinusitis / 国际眼科杂志(Guoji Yanke Zazhi)

@#AIM: To investigate the prognostic value of DIP endoscopic scoring system for simultaneous operation of chronic dacryocystitis complicated with sinusitis.METHODS: From January 2018 to February 2021, 96 patients(96 eyes)with chronic dacryocystitis complicated with sinusitis who underwent nasal endoscopic sinus surgery and dacryocystorhinostomy were enrolled in a prospective single-blind study. Patients were examined by nasal endoscopy and recorded video to get DIP endoscopic score before operation. The patients were followed-up for 6mo, and the curative effect was based on the results of the last follow-up. The receiver operating characteristic curve(ROC curve)was drawn according to DIP endoscopic scoring system and postoperative curative effect, and the value of DIP endoscopic scoring system in predicting the prognosis of nasal endoscopic sinus surgery combined with dacryocystorhinostomy was evaluated. According to the best cutoff value obtained by ROC curve analysis, patients were analyzed in subgroups, and the age and sex constituent ratio of two groups were compared. RESULTS: Among the 96 eyes with chronic dacryocystitis complicated with sinusitis, 86 eyes(90%)were cured, 4 eyes(4%)were improved, and 6 eyes(6%)were invalid. ROC curve analysis showed that the area under the ROC curve(AUC)of DIP endoscopic score for predicting the curative effect of nasal endoscopic sinus surgery combined with dacryocystorhinostomy was 0.905. When Yoden index reached its peak, the DIP endoscopy score was 16.5 as the best cutoff value. At the same time, the sensitivity was 80.0% and the specificity was 86.0%. In the subgroup analysis, there was no significant difference in age and sex constituent ratio between the two groups(<i>P</i>>0.05); The surgical efficiency of patients with DIP endoscopic score <16.5 was better than the patients with DIP endoscopic score ≥16.5(<i>P</i><0.05).CONCLUSION: DIP endoscopic scoring system has a good predictive value for the prognosis of endoscopic of transnasal endoscopic sinus opening combined with dacryocystorhinostomy.

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.

@#AIM: To analyze the difference of the angle between the long axis of lacrimal sac and bony nasolacrimal duct(BNLD)in patients with chronic dacryocystitis and normal eyes, and discuss the relationship between the angle and chronic dacryocystitis.<p>METHODS:A total of 218 patients(248 diseased eyes)from Sichuan Province who visited the ophthalmology department of our hospital from January 2016 to March 2019 were collected retrospectively. All patients underwent computed tomography dacryocystography(CT-DCG)immediately after bilateral lacrimal duct irrigation, and three-dimensional reconstruction of the nasolacrimal duct structure was performed. The structures of the nasolacrimal duct, lacrimal sac and its surrounding tissues were observed in the coronal position, and the lacrimal sac-BNLD angles of the diseased eyes and the normal eyes were measured respectively.<p>RESULTS:The lacrimal sac-BNLD angle of the diseased eyes \〖23.55°(17.30°, 29.90°)\〗 was higher than that of the normal eyes \〖20.05°(15.40°, 28.35°)\〗(<i>P</i><0.05). Among them, the angle of the diseased eyes in female patients \〖24.60°(17.75°, 31.00°)\〗 was significantly higher than that in normal eyes \〖21.15°(15.10°, 27.35°)\〗(<i>P</i><0.05), while there was no significant difference in the angle between the diseased eyes and normal eyes in male patients(<i>P</i>>0.05). In addition, the angle of the diseased eyes in the age group of 41-60 a \〖25.20°(17.90°, 33.00°)\〗 was significantly higher than that in normal eyes \〖21.60°(15.25°, 29.05°)\〗(<i>P</i><0.05).<p>CONCLUSION: The angle between the long axis of lacrimal sac and bony nasolacrimal duct increased in patients with chronic dacryocystitis, which may be one of the factors causing the onset of chronic dacryocystitis in middle-aged and elderly women.

Compared outcomes of using histoacryl and tube insertion for endoscopic endonasal dacryocystorhinostomy surgery / Шинэ санаа Шинэ нээлт

Background@#Dacryocystorhinostomy (DCR) is a surgical treatment for site of obstruction in the nasolacrimal duct system [1]. This surgery is performed in cases of congenital nasolacrimal obstruction, partial and complete occlusion of the nasolacrimal duct in adults, chronic tearing disorders, ineffective probing treatment and placement of a silicone tube in the nasolacrimal system [2,3]. the present findings indicate that preservation of lacrimal sac flaps with end-to-end anastomosis to the nasal mucosa using histoacryl has a positive impact on surgical outcome in patients undergoing endonasal endoscopic dacryocystorhinostomy [4]. Histoacryl glue is one of the most commonly surgical materials used recently. The basis of our study is the lack of research on the use of this glue in the practice of oculoplastic and reconstructive surgery.@*Purpose@#The purpose of this study to comparing outcomes of surgical methods of histoacryl glue and silicone tube during endoscopic endonasal dacryocystorhinostomy.@*Methods@#Retrospective, case series study. The study included 83 patients who underwent endonasal endoscopic dacryocystorhinostomy between January 2017 to June 2020. Whole case was divided into two groups. In group 1, an anastomosis was made during surgery by using histoacryl glue to the posterior wall of the lacrimal sac and the wall formed by the nasal mucosa [5]. In group 2, a silicone tube was placed in the nasolacrimal duct during endonasal dacryocystorhinostomy and the results were evaluated in the 1st, 3rd, 6th, and 12th months after surgery. Statistical calculations were performed using SPSS software.@*Results@#The age of the whole cases was between 17 and 82 years. There were no significant difference among the age groups. In terms of gender, n=48 (78.7%) were female and n=13 (21.3%) were male, indicating that dacryocystitis was predominant in women. Study reports no significant difference in intraoperative and postoperative complication. The surgical success rate was significantly higher in histoacryl group 94.9%, than silicone tube group 79.5%. Recurrent cases n=2 (5.1%) in group 1 and n=9 (20.4%) in group 2 respectively. @*Conclusion@#Histoacryl glue is highly effective, commodity, inexpensive and easy to apply during endonasal endoscopic dacryocystorhinostomy surgery.

Introduction@#Dacryocystorhinostomy (DCR) is a surgical treatment for site of obstruction in the nasolacrimal duct system. This surgery is performed in cases of congenital nasolacrimal obstruction, partial and complete occlusion of the nasolacrimal duct in adults, chronic tearing disorders, ineffective probing treatment and placement of a silicone tube in the nasolacrimal system. the present findings indicate that preservation of lacrimal sac flaps with end-to-end anastomosis to the nasal mucosa using histoacryl has a positive impact on surgical outcome in patients undergoing endonasal endoscopic dacryocystorhinostomy. Histoacryl glue is one of the most commonly surgical materials used recently. The basis of our study is the lack of research on the use of this glue in the practice of oculoplastic and reconstructive surgery.@*Purpose@#To report the use of fibrin glue as an adjunctive procedure in endoscopic dacryocystorhinostomy (En-DCR) surgery and compare it to silicone tubing@*Material and Method@#Patients with primary nasolacrimal duct obstruction were retrospectively reviewed for endo-DCR between January 2017 and December 2019. Group I patients applied fibrin glue and Group II used silicone tube insertion. The fibrin glue group received end-to-end anastomosis of the nasal mucosa and lacrimal sac using fibrin glue at the end of surgery. The demographics, recurrence, causes of failure, formation of scars, final ostium size and the success rate were compared. This study was approved by the Institutional Review Board of the Chang Gung Memorial Hospital Clinical Research Ethnics Committee and followed the Declaration of Helsinki. All statistical analysis was performed with SPSS version 24.0 software (SPSS Inc., Chicago, IL, USA), and a P value < .05 was considered statistically significant. Continuous variables were presented as mean ± standard deviation, while categorical data was represented as numbers and percentages. Independent t-tests were used to compare the differences in parametric variables. The Mann-Whitney U test was performed to compare the follow-up period. Pearson’s chi-squared and Fisher’s exact tests were used to compare categorical variables. Multivariate logistic regression was used to identify the risk factors associated with recurrence. @*Result@#The age of the whole cases was between 17 and 82 years. There was no significant difference among the age groups. In terms of gender, n=48 (78.7%) were female and n=13 (21.3%) were male, indicating that dacryocystitis was predominant in women. Study reports no significant difference in intraoperative and postoperative complication. The surgical success rate was significantly higher in histoacryl group 94.9%, than silicone tube group 79.5%. Recurrent cases n=2 (5.1%) in group 1 and n=9 (20.4%) in group 2 respectively.@*Conclusion@#Fibrin glue improves the surgical outcome in patients undergoing Endo-DCR compared to commonly used silicone stenting by securing flaps apposition and maintaining the ostium opening.

Analysis of the neonatal dacryocystitis treated by lacrimal passage probing in ambulatory surgery mode during the prevalence of COVID-19 / 国际眼科杂志(Guoji Yanke Zazhi)

@#AIM: To analyze the clinical efficacy of neonatal dacryocystitis treated by the lacrimal passage probing(LPB)in ambulatory surgery mode during the prevalence of the COVID-19, and to provide a theoretical basis for the development and promotion of daytime operation mode of LPB in neonatal dacryocystitis.<p>METHODS: The information of 215 cases with neonatal dacryocystitis treated by LPB with ambulatory surgery mode was analyzed retrospectively, including the cure rate, the incidence of complications and adverse reactions, as well as the reasons for not arriving at the hospital after appointment.<p>RESULTS: All patients accomplish LPB surgery and daytime operation management successfully. The success rate of LPB for neonatal dacryocystitis with ambulatory surgery mode was 99.6%, with few postoperative complications and adverse reactions. The reason why the children did not arrive at the hospital after appointment was mainly due to the sickness being catching a cold, pneumonia, diarrhea and other diseases, otherwise, they had to cancel or postponed the appointment.<p>CONCLUSION: In the course of the prevalence of the COVID-19, LPB in the treatment of neonatal dacryocystitis in ambulatory surgery mode is safe, effective and feasible. It can reduce hospitalization expenses, shorten hospitalization time, and is more conducive to the prevention and control of COVID-19, which is worthy of popularization and application.
