Long-term Follow-up Results of Primary Canaliculitis Patients.

Objectives: To evaluate the demographic characteristics, clinical presentation, microbiologic profile, and treatment results of patients with primary canaliculitis. Materials and Methods: Patients diagnosed and treated for primary canaliculitis between May 2014 and May 2021 were analyzed retrospectively. Results: There were 26 patients with primary canaliculitis, including 17 females (65.4%) and 9 males (34.6%) with a mean age of 50.6±16.4 years (range: 9-80 years). Canaliculitis affected the right eye in 11 patients, the left eye in 13 patients, and bilateral involvement was seen in 2 patients. Inferior canaliculus involvement was more frequent (73%). The most common complaint was epiphora (46.1%). Five patients (19.2%) were wrongly diagnosed as chronic conjunctivitis. The time interval between the beginning of symptoms and canaliculitis diagnosis was 18.2±14.3 months (range: 1-60 months). Canaliculotomy and curettage of canalicular content with dacryolith removal were performed in 23 patients. After surgery, antibiotic irrigation of the canaliculus was added to the treatment regimen in 12 of these 23 patients. Intracanalicular antibiotic therapy was administered to the remaining 3 patients. The most cultured organism was Actinomyces (6 patients). Gemella (1 patient), Porphyromonas (1 patient), Candida parapsilosis (1 patient), Citrobacter koseri (1 patient) were also grown in culture. The follow-up time of patients was 26.2±23.7 months (range: 6-83 months). All symptoms and findings resolved in all patients in one month. In two patients, recurrence occurred at 4 and 16 months after surgical treatment. With appropriate treatment, no further recurrence was seen in either patient over 24-month follow-up. One patient presented with iatrogenic canaliculus blockage during follow-up. Conclusion: Primary canaliculitis is often overlooked and can be misdiagnosed. The most common symptom was epiphora. All patients with epiphora and chronic conjunctivitis should be examined carefully for canaliculitis.

Microbial distributions in the conjunctiva and lacrimal sacs of patients with chronic dacryocystitis in a tertiary hospital.

BACKGROUND: The aim was to clarify the distributions of bacteria in the conjunctival sac and lacrimal sac in patients with chronic dacryocystitis. METHODS: In total, 297 (322 eyes) chronic dacryocystitis patients who underwent nasal endoscopic dacryocystorhinostomy (EN-DCR) were included. Conjunctival sac secretions from the affected eye were collected preoperatively, and lacrimal sac retention fluid from the affected side in the same patient was collected intraoperatively. Bacterial culture and drug sensitivity testing were performed to determine bacterial distributions. RESULTS: In total, 127 bacterial isolates (49 species) were detected in 123 eyes in the conjunctival group, with a positivity rate of 38.2% (123/322); 85 bacterial isolates (30 species) were detected in 85 eyes in the lacrimal sac group, with a positivity rate of 26.4% (85/322). The positivity rates were significantly different (P = 0.001) between two groups. The gram-negative bacilli proportion in the lacrimal sac group (36/85, 42.4%) was significantly higher than that in the conjunctival sac group (37/127, 29.2%) ( P = 0.047). Positive conjunctival sac secretion culture (123/322) was significantly associated with increased ocular secretion (281/322, 87.3%) (P = 0.002). Among the culture-positive bacteria in the conjunctival sac group and the lacrimal sac group, 30/127, 23.6% and 43/127, 26.7% and 21/85, 24.7% and 20/85, 23.5% were resistant to levofloxacin and tobramycin, respectively. CONCLUSIONS: This study illustrated differences in bacterial distributions between conjunctival sac secretions and retained lacrimal sac fluid in chronic dacryocystitis patients, with a higher proportion of gram-negative bacilli in lacrimal sac secretions. The ocular surface flora in chronic dacryocystitis patients is partially resistant to levofloxacin and tobramycin, which need to be considered by ophthalmologists.

Predictors of surgical intervention and visual outcome in bacterial orbital cellulitis.

ABSTRACT: This study aims to identify predictive factors associated with surgical intervention and the visual outcome of orbital cellulitis and to evaluate the treatment outcomes.A retrospective study involving 66 patients (68 eyes; 64 unilateral and 2 bilateral) diagnosed with bacterial orbital cellulitis was conducted between November 2005 and May 2019.The mean (± standard deviation) age was 42.1 (± 25.8) years (range: 15 days-86 years). Sinusitis was the most frequent predisposing factor, occurring in 25 patients (37.9%), followed by skin infection in 10 patients (15.2%), and acute dacryocystitis in 9 patients (13.6%). Subperiosteal abscesses were found in 24 eyes and orbital abscesses in 19 eyes. Surgical drainage was performed in 31 eyes. Regarding the abscess volume for surgical drainage, a cut-off of 1514 mm3 showed 71% sensitivity and 80% specificity. There was significant improvement in visual acuity (VA) and decrease in proptosis after treatment (for both, P ≤ .001). Only pre-treatment VA ≤20/200 was a significant predictor for post-treatment VA of 20/50 or worse (adjusted odds ratio: 12.0, P = .003). The presence of a relative afferent pupillary defect was the main predictor of post-treatment VA of 20/200 or worse (adjusted odds ratio: 19.0, P = .003).The most common predisposing factor for orbital cellulitis in this study was sinusitis. VA and proptosis significantly improved after treatment. We found that the abscess volume was strongly predictive of surgical intervention. Pre-treatment poor VA and the presence of relative afferent pupillary defect can predict the worst visual outcome. Hence, early detection of optic nerve dysfunction and prompt treatment could improve the visual prognosis.

The microbiologic spectrum of dacryocystitis.

BACKGROUND: To investigate the microbiologic spectrum of dacryocystitis in adult and pediatric groups, specifically the microbiologic differences between chronic dacryocystitis with nasolacrimal duct obstruction (NLDO) and acute dacryocystitis in pediatric group. METHODS: This retrospective study was reviewed for demographic and microbiologic profile of dacryocystitis. The culture results were reported. RESULTS: Sixty-four adults and one hundred and five pediatrics with dacryocystitis were included in this study. Of all adults, only chronic dacryocystitis with NLDO was observed. Of all pediatric patients, 89 had chronic dacryocystitis with NLDO and 16 had acute dacryocystitis. Gram positive and negative isolates were numerically equal in adult group (both 36(48.65%)), while gram positive isolates were the major organism in pediatric group (71(58.68%)). Streptococcus pneumonia was the most common isolate in both adult (11(14.86%)) and pediatric (30(24.79%)) dacryocystitis. For both pediatric subgroups, gram positive isolates were the major organism (59(57.84%) for chronic dacryocystitis with NLDO and 12 (63.16%) for acute dacryocystitis). However, the leading isolates in those two subgroups were distinct, with Streptococcus pneumonia (29(28.43%)) being most common in chronic dacryocystitis with NLDO and Staphylococcus aureus (8(42.11%)) being most common in acute dacryocystitis. CONCLUSIONS: In adult group, gram negative isolates were more common in dacryocystitis than before. In pediatric group, gram positive isolates were still the major infection pathogen. Moreover, the more virulent organisms were more common in acute dacryocystitis than chronic dacryocystitis with NLDO.

Isolated Meningitis and Lacrimal Gland Abscess due to Odontogenic Sinusitis: Case Report / Meningitis Aislada y Absceso de la Glándula Lagrimal debido a Sinusitis Odontogénica: Reporte de un Caso

ABSTRACT: Our objective was report an extremely rare case of isolated meningitis and suppurative dacrioadenitis as consequences of odontogenic sinusitis. We describe the diagnostic tools including imaging and culture, as well as surgical treatment and follow-up. Our final diagnosis was odontogenic sinusitis caused by Streptococcus Anginosus complicated by isolated meningitis and lacrimal gland abscess. Urgent surgical treatment to restore the paranasal sinuses and drainage of the lacrimal gland was performed. Culture from purulent material collected from maxillary sinus indicated the targeted therapy. Clinical assessment and imaging obtained 20 days after surgery demonstrated successful results. This case emphasizes the importance of evaluating intracranial complications of rinosinusitis, the need to search for a dental infection when a maxillary sinusitis is encountered, the key role of a thorough diagnostic workup in order to plan a comprehensive and effective surgical treatment, as well as targeted medical therapy.

RESUMEN: En este estudio se informa un caso extremadamente raro de meningitis aislada y dacrioadenitis supurativa, como consecuencia de sinusitis odontogénica. Describimos las herramientas de diagnóstico que incluyen imágenes y cultivo, como también el tratamiento quirúrgico y el seguimiento. El diagnóstico final fue de sinusitis odontogénica causada por estreptococo anginoso complicado por una meningitis aislada y el absceso de la glándula lagrimal. Se realizó un tratamiento quirúrgico de urgencia para restaurar los senos paranasales y drenar la glándula lagrimal. Se determinó el tratamiento de acuerdo a los resultados de cultivo del seno maxilar. La evaluación clínica y las imágenes obtenidas 20 días después de la cirugía demostraron resultados exitosos. Es importante la evaluación de las complicaciones intracraneales de la rinosinusitis además de la necesidad de considerar una infección dental frente a una sinusitis maxilar. Por otra parte, es clave una evaluación exhaustiva de diagnóstico para planificar un tratamiento quirúrgico completo y efectivo, así como el tratamiento médico.

Bilateral tuberculous dacryoadenitis.

Tuberculosis is a real public health problem in developing countries. The ophthalmic form is a rare clinical entity. Dacryoadenitis presents an exceptional manifestation. We report the case of a 45-year-old female who presented with a 1-month history of painless bilateral dacryoadenitis with a normal initial work-up. Anatomopathological examination of the lacrimal glandular tissue showed a gigantic epithelioid granuloma with caseous necrosis confirming the diagnosis of tuberculosis. The search for a primary focus was negative. Evolution was good under anti-tuberculosis chemotherapy. The objective of this work is to think of the tuberculous etiology when having dacryoadenitis in an endemic country.

Presentation, Diagnostic Evaluation, Management, and Rates of Serious Bacterial Infection in Infants With Acute Dacryocystitis Presenting to the Emergency Department.

BACKGROUND: Dacryocystitis is considered benign, yet infants represent a population at risk of complications. The presentation, management, and rates of serious bacterial infection in infants with dacryocystitis have not been described. METHODS: We conducted a retrospective study of infants (12 months or younger) presenting to a single urban tertiary care pediatric emergency department between January 1995 and March 2014 with concern for dacryocystitis. Exclusion criteria included immune compromise or craniofacial anomalies. Cases were identified using text search software, followed by manual chart review. RESULTS: We identified 333 subjects, and median age was 38 days (interquartile range, 12; 106). Fifty-three percent were female. Most were afebrile (81%, T < 38°C) at triage while 6% had fever of ≥39°C. Two of 135 blood cultures sent were positive (both Streptococcus pneumoniae). Lumbar punctures were performed on 40 patients (12%), and no cerebrospinal fluid (CSF) cultures were positive. Eye cultures were positive in 47% (N = 58) of infants cultured (N = 123); the most common pathogens were Haemophilus species (N = 17), Staphylococcus aureus (N = 13), Gram-negative rods (N = 7), and Moraxella species (N = 4). Imaging was obtained in 11 subjects (3.3%) with 3 demonstrating cellulitis and 1 a hemangioma. Ophthalmology was consulted for 21%, and an intervention/probe performed in 6%. Topical antibiotics were used in 147 subjects (44%), oral antibiotics in 100 (33%), and parenteral antibiotics in 87 (26%). CONCLUSION: Infants with dacryocystitis have a variable presentation and management ranges from observation to aggressive management. The rates of serious bacterial infection were low in this sample and not associated with any presenting risk factors.

Pediatric acute dacryocystitis due to Eikenella corrodens: A case report.

Eikenella corrodens is a facultatively anaerobic gram-negative rod bacterium in the oropharynx and respiratory tract. It is a member of HACEK (Haemophilus spp., Aggregatibacter spp., Cardiobacterium hominis, E. corrodens, and Kingella kingae) group commonly associated with endocarditis and craniofacial infections. It is usually susceptible to penicillin, second and third-generation cephalosporins, and carbapenem, but has variable susceptibility to first-generation cephalosporin. We herein provide a description of the first case of pediatric acute dacryocystitis caused by E. corrodens. The patient did not respond to oral cephalexin and required surgical drainage followed by intravenous cefotaxime. Also provided is a brief review of the current literature.

Are systemic antibiotics required during and after dacryocystitis-related dacryocystorhinostomy?

PURPOSE: To compare the outcomes of patients with and without a history of dacryocystitis that undergo dacryocystorhinostomy without systemic intra- and post-operative antibiotics. METHODS: A retrospective review was performed to identify all cases of patients that received surgery under this paradigm and had at least three months of follow up care. Key demographic and outcome data were captured, and a statistical analysis was performed via a dedicated software package (Microsoft Excel, Redmond, WA). RESULTS: For the study period, 83 patients without and 69 patients with a history of dacryocystitis were identified, and the two groups were not statistically significantly different in age, gender, or postoperative follow up duration (mean = 6.4 months for patients without and 6.3 months for those with dacryocystitis, respectively). No patient developed a postoperative infection or a recurrence of dacryocystitis during the follow up period. DISCUSSION: While many surgeons routinely use systemic antibiotics in patients with a history of dacryocystitis who undergo dacryocystorhinostomy, these agents may not be necessary. As a result, patients may be able to avoid the complications and side effects inherent to systemic antibiotics. Large-scale, prospective studies will likely help to further clarify this issue.

Tuberculosis presenting as dacryoadenitis in the USA.

A 25-year-old Filipino woman living in the USA was evaluated for a 5-month history of left eye pain and a subsequent orbital mass. Histopathological analysis of the lacrimal mass showed a mixed inflammatory process with necrotising granulomas and positive cultures for Mycobacterium tuberculosis She was treated with antituberculosis therapy, with resolution of symptoms. Tuberculosis dacryoadenitis is extremely rare in the USA and other developed countries. It requires a high degree of clinical suspicion with special attention to the patient's history to make the correct diagnosis. It can be treated successfully with antituberculosis therapy.

Dacryoadenitis Caused by Blastomycosis: A Case Report.

This is the first case of histopathologically proven blastomycosis involving the lacrimal gland. A 51-year-old woman with a history of disseminated blastomycosis involving her lungs and skin, on oral itraconazole, presented with 3 days of right upper eyelid swelling, erythema, and pain concerning for recurrent dacryoadenitis. MRI showed enlargement of the right lacrimal gland with a cystic lesion at the anterior aspect of the gland with a radiographic differential diagnosis of abscess versus cyst. After no improvement with intravenous antibiotics, orbitotomy with lacrimal gland biopsy and incision and drainage of the cystic lesion were performed. Culture and pathology of the drained fluid demonstrated an abscess with both viable and nonviable broad-based budding yeast consistent with partially treated blastomycosis. The patient's symptoms improved after the surgery and continued itraconazole therapy.

The Role of Bacterial Etiology in the Tear Duct Infections Secondary to Congenital Nasolacrimal Duct Obstructions.

PURPOSE: To define the microbiological features of dacryocystitis in childhood. METHODS: Patients with dacryocystitis secondary to CNLDO between 2017 and 2019 in Izmir, Turkey were included in the study. Inclusion criteria of the study were: mucopurulent secretion, being under 4 years old and not having received prior antibiotic treatment. Samples from secretion were cultivated in sheep blood agar, eosin methylene blue, and chocolate agar. Reproduction was checked intermittently. Clinically significant growths were reported. RESULTS: Seventy patients with dacryocystitis secondary to CNLDO were included in the study. Sixty percent of patients were female (n = 42) and 40% (n = 28) percent of patients were male. The average age of participants was 2.09 ±â€Š0.68 (1-3) years old. Positive bacterial proliferation results were noted in 20 patients (28.6%). Eighty percent (n = 16) of culture-positive bacterias were gram-negative bacterias and 20% (4) were gram-positive bacterias. Twenty percent of culture-positive bacterias were aerobic and 80% were facultative bacterias. The most common bacteria seen in culture specimen was Haemophilus 40% (Haemophilus haemolyticus [20%] and Haemophilus influenzae [20%]). CONCLUSIONS: Gram-negative organisms especially Haemophilus were most prevalent. These findings could be helpful for antibiotic selection.

Paediatric orbital and periorbital infections.

PURPOSE OF REVIEW: This study is a review of recent literature in the diagnosis and management of preseptal cellulitis, orbital cellulitis and dacryocystitis, including causative organisms, diagnosis and medical or surgical therapy and potential complications. RECENT FINDINGS: Advances in vaccination against Haemophilus influenzae B have resulted in a shift in the most common causative organisms of preseptal and orbital cellulitis. Management of orbital cellulitis has been advanced by adjuvant corticosteroids, and subperiosteal abscess volumes of more than 1250 ml has been shown as predictive for requiring potential surgical intervention. SUMMARY: Periorbital infections require prompt evaluation and management. Although the infectious organisms in both preseptal and orbital cellulitis include Staphylococcus/Streptococcus species, management may differ significantly on the basis of the nidus of infection, presenting signs and symptoms, and response to initial medical management.

A Rare Complication of Oropharyngeal Tularemia: Dacryocystitis

Tularemia is a zoonotic disease caused by Francisella tularensis, a highly virulent gram-negative coccobacillus. Oropharyngeal tularemia, one of the clinical subtypes, is the most common clinical form of the disease in Eastern Europe, including Turkey. This clinical form affects mostly the head and neck region and the most common complaints of patients are mass in the neck, sore throat, and fever. This form of tularemia may be confused with tonsillitis, pharyngitis, or cervical lymphadenitis caused by other microbial agents due to the nonspecific clinical and laboratory features. In this study, we present a patient with nasolacrimal duct obstruction and dacryocystitis caused by oropharyngeal tularemia.

High Prevalence of Biofilm-Forming MRSA in the Conjunctival Flora in Chronic Dacryocystitis.

OBJECTIVES: To report the microbiological spectrum of conjunctival flora and prevalence of biofilm-forming Methicillin-resistant Staphylococcus aureus (MRSA) in conjunctival flora in chronic dacryocystitis. DESIGN: Prospective, case-control study. METHODS: We included patients with unilateral chronic dacryocystitis, and their unaffected eyes as control. Microbiological profile and antibiotic susceptibility of the isolates was determined by standard microbiological procedures. S. aureus isolates were further evaluated for Methicillin resistance by Oxacillin resistance screening agar method and mecA polymerase chain reaction (PCR) and for biofilm synthesis by Congo red agar method, Microtitre plate (MTP) assay, and ica A and ica D PCR. RESULTS: We found 95 patients with unilateral chronic dacryocystitis. Aerobic Gram-positive isolates (74.2%, n = 72) were more than Gram-negative (25.7%, n = 25) or anaerobic isolates (20.5%, n = 25). S. aureus was most common (46.4%, n = 45), followed by Pseudomonas aeruginosa (10.3%, n = 10). Gram-positive isolates showed highest sensitivity to Linezolid (100%) and higher generation fluoroquinolones. Gram-negative isolates showed good sensitivity (>90%) to all tested antibiotics. S. aureus isolates showed MRSA prevalence as 93.5% and 96.9% by Oxacillin resistance screening agar method and mecA PCR, respectively. Biofilm formation was found in 71.8% MRSA isolates by MTP assay and 58.1% MRSA isolates were resistant to ≥3 classes of antibiotics. CONCLUSIONS: Gram-positive organisms, specifically S. aureus, are the major etiological agent in chronic dacryocystitis. There is high prevalence of MRSA in these isolates and concurrent biofilm formation.

Dacryoadenitis due to gonococcal conjunctivitis complicated by corneal perforation.

Adnexal and periocular involvement in Neisseria gonorrhoeae (NG) infection is rare. This report describes the case of a patient with a delayed diagnosis of gonococcal dacryoadenitis with contiguous conjunctivitis and corneal involvement. She underwent extensive inpatient laboratory and infectious workup but rapidly progressed to corneal perforation requiring emergent penetrating keratoplasty prior to a positive culture confirming the diagnosis. To date, this is the first reported case of ophthalmologic NG infection with associated conjunctivitis, dacryoadenitis, and corneal perforation.

The microbiologic profile of dacryocystitis.

PURPOSE: Recent studies suggest an increasing incidence of gram-negative bacteria and methicillin-resistant Staphylococcus aureus in dacryocystitis. Since patients are often treated empirically without culture data, a changing microbiologic profile will markedly affect the success of oral treatment. To provide current guidelines for the treatment of this common condition, we investigated the microbiology and antibiogram of dacryocystitis seen at our institution. METHODS: The charts of all patients presenting with acute and/or chronic dacryocystitis in University Hospital, Newark, from 2007 to 2015 were reviewed. Patient demographics, culture isolates, and in vitro antimicrobial susceptibility data were collected. Additional sensitivity data were obtained from the Sanford Guide to Antimicrobial Therapy. RESULTS: A total of 137 patients were included in the study. Of 205 samples collected, S. aureus was the most commonly isolated organism (46 of 156, 30%) followed by Pseudomonas species (19 of 156, 12%) and Propionibacterium acnes (15 of 156, 10%). Based on sensitivity data, the two oral antibiotics that would have been most effective in this population were levofloxacin and amoxicillin/clavulanate; however, even these antibiotics would have encountered at least one resistant organism in 16% and 32% of patients, and potentially in another 15% and 8% of patients, respectively. CONCLUSIONS: Given the broad range of causative organisms, routine treatment of dacryocystitis with any specific antibiotic may fail in up to one-third of patients. Obtaining a culture at the time empiric antibiotic treatment is initiated can prove extremely valuable when treating patients with dacryocystitis.

Long-Term Outcomes of Oral Anti-Tubercular Therapy in Patient with Tubercular Dacryoadenitis: A Case Series.

Purpose: To describe the clinico-radiological features and long-term outcomes in patients with tubercular dacryoadenitis (TbD) Methods: Retrospective, observational study of TbD patients who underwent a thorough clinical examination, orbital imaging study, and tailored ancillary investigations. Polymerase chain reaction (PCR) and microscopy were done in specific cases. A 4-drug anti-tubercular therapy (ATT) was started and clinical response was monitored in all. Patients with a minimum follow-up of 6 months "off-ATT" were included. Results: All patients were women and three presented with pain, blepharoptosis, and bilateral involvement. In all, ESR was raised, Mantoux test was positive and orbital imaging revealed enlarged lacrimal gland/s. Positive PCR and granulomatous inflammation on microscopy were seen in two patients. At a mean follow-up of 17.25 months, all women responded with no relapse or clinical recurrence. Conclusion: Bilateral lacrimal gland enlargement, positive Mantoux & PCR with early response to ATT may provide sufficient evidence for diagnosing TbD.

Primary tubercular dacryocystitis - a case report and review of 18 cases from the literature.

Tuberculosis is an airborne communicable disease primarily affecting lungs. Primary tuberculosis of the lacrimal sac is very rare. A 15-year-old girl presented with bilateral epiphora for 8 months. Examination revealed bilateral nasolacrimal duct obstruction. During dacryocystorhinostomy, bone over lacrimal sac was found partially eroded. Lacrimal sac was found filled with caseous white material. Biopsy from the lacrimal sac revealed tubercular granulomas. Patient improved after anti-tubercular therapy. Abbreviations: PCR: polymerase chain reaction; NAAT: nucleic acid amplification test.
