1/9. brucella melitensis dacryoadenitis: a case report.PURPOSE: To present a case of brucellosis-related unilateral dacryoadenitis. methods: A 16-year-old boy had unilateral lacrimal gland enlargement, shown by magnetic resonance imaging of the orbits. Clinical findings, tube agglutination, the culture of a lacrimal gland aspirate, and histopathological examination confirmed the diagnosis of brucellosis. RESULTS: Tube agglutination testing for brucellosis gave a titer of over 1/640. The aspirate from the lacrimal glands grew brucella melitensis and histopathological findings were consistent with brucellosis. CONCLUSIONS: Dacryoadenitis may occur in the course of systemic brucellosis caused by brucella melitensis.- - - - - - - - - - ranking = 1keywords = dacryoadenitis (Clic here for more details about this article) |
2/9. Combined coliform and anaerobic infection of the lacrimal sac.A case is reported of combined coliform and anaerobic bacterial infection of the lacrimal sac, a condition of which there is only one other published case report. In addition, a literature review is presented of the bacteriology of acute dacryocystitis as it applies to this case. Recommendations for the microbiological investigation and management of acute dacryocystitis are made.- - - - - - - - - - ranking = 2.5100796272461keywords = dacryocystitis (Clic here for more details about this article) |
3/9. dacryocystorhinostomy for dacryocystitis caused by methicillin- resistant Staphylococcus aureus: report of four cases.BACKGROUND: To evaluate the outcome of dacryocystorhinostomy (DCR) for dacryocystitis caused by methicillin-resistant staphylococcus aureus (MRSA). CASES: Four otherwise healthy patients with dacryocystitis caused by MRSA were studied (3 with chronic dacryocystitis; 1, acute dacryocystitis). Ophthalmic symptoms were epiphora with purulent discharge in 2 cases, with blepharoconjunctivitis in 1 case, and with lacrimal fistula in 1 case. culture of the purulent discharge from the affected conjunctival sacs revealed MRSA infection. Initial treatment, which was unsuccessful, included intravenously administered common antibiotics, the use of topical antibiotics and povidone-iodine in the conjunctival sac and mupirocin ointment in the nasal cavity. Subsequently, standard DCR was performed with a bicanalicular silicone tube inserted under local anesthesia, accompanied by the administration of common antibiotics. observation: Cultures from all patients were negative for MRSA as soon as 4 days after DCR. None of the patients had epiphora with pus, and the lacrimal passage became patent postoperatively. CONCLUSION: dacryocystitis due to MRSA was resistant to conservative therapy. DCR subsequent to the conservative therapy resulted in almost immediate resolution of the lacrimal fistula and nasolacrimal obstruction, rapid control of dacryocystitis, and a decrease in the period of MRSA infection in the conjunctiva and the nasal cavity.- - - - - - - - - - ranking = 11.295358322607keywords = dacryocystitis (Clic here for more details about this article) |
4/9. Bilateral dacryocystitis after punctal occlusion with thermal cautery.A 61-year-old woman developed acute bilateral dacryocystitis secondary to Staphylococcus aureus 3 weeks after undergoing punctal occlusion with thermal cautery for keratoconjunctivitis sicca. The dacryocystitis resolved with intravenous antibiotics, aspiration of the lacrimal sacs, injection of sulfacetamide into the lacrimal sacs, and bilateral dacryocystorhinostomy. Preexisting bilateral nasolacrimal duct obstruction was postulated as the underlying cause. In these cases, irrigation of the lacrimal system is recommended before proceeding with punctal occlusion.- - - - - - - - - - ranking = 7.5302388817382keywords = dacryocystitis (Clic here for more details about this article) |
5/9. bacteriology of chronic dacryocystitis in a tertiary eye care center.PURPOSE: To determine the current bacteriology of adult chronic dacryocystitis in a tertiary eye care center and compare it with previously reported studies. methods: Clinical and microbiological records of patients with diagnosis of chronic dacryocystitis between January 1999 and March 2002 were reviewed for age, sex, lacrimal sac side involved, and culture results. patients younger than 16 years of age and patients who were receiving any systemic or topical antibiotics were excluded from the study. RESULTS: One hundred eighty-eight adult patients with an average age of 50.5 years (range, 16 to 91 years), who had a diagnosis of chronic dacryocystitis, were identified. The study was predominated by female subjects (65.4%). Of the cultures from the nasolacrimal sac, 183 (97.3%) were positive for bacteria, with an average of 2.3 (1 to 6) microorganisms. More than 2 microorganisms were present in 66.1% of the cultures, whereas a single microorganism was recovered from 33.9% of the cultures. The majority of microorganisms in our study were gram-positive bacteria, representing 53.7% of the overall microorganisms cultured with a predominance of Staphylococcus species. gram-negative bacteria were recovered from 26.0% of the specimens with predominance of haemophilus influenzae. Anaerobic microorganisms were present in 19.1% of the samples. The most frequently isolated anaerobic microorganisms were propionibacterium acne and peptostreptococcus species. CONCLUSIONS: Several bacterial species may be involved in the pathogenesis of chronic dacryocystitis in adults, and the majority of patients harbor multiple microorganisms in their nasolacrimal sacs. The high rate of microorganism-positive lacrimal sac cultures suggests that adult patients should be treated for their infection before any intraocular surgery because of the potential risk of infection.- - - - - - - - - - ranking = 10.040318508984keywords = dacryocystitis (Clic here for more details about this article) |
6/9. Chronic dacryocystitis caused by mycobacterium fortuitum.PURPOSE: To characterize the clinical presentation of mycobacterium fortuitum dacryocystitis, an unusual microbial cause of this disease. methods: The authors present a detailed description of a case of M. fortuitum chronic dacryocystitis and a review of the literature. FINDINGS: Although M. fortuitum is a well-recognized cause of chronic keratitis and corneal ulcer, it has only been reported once previously as a cause of dacryocystitis. Multiple factors that alter the ocular environment of the host may predispose to infection with this organism. The diagnosis requires isolation of the organism in the appropriate clinical setting. The authors' case represents the first patient successfully treated with dacryocystectomy. CONCLUSION: M. fortuitum is a rare cause of chronic dacryocystitis that may respond favorably to surgical therapy alone.- - - - - - - - - - ranking = 10.040318508984keywords = dacryocystitis (Clic here for more details about this article) |
7/9. Pseudodacryocystitis arising from anterior ethmoiditis.The contiguous spread of inflammation from infected ethmoid sinuses to the surrounding tissues of the lacrimal drainage system can produce symptoms easily confused with acute dacryocystitis. We report the cases of two patients with presumed dacryocystitis whose patency of the lacrimal apparatus was established by probing, irrigation, and dacryocystography. Computerized tomography and magnetic resonance imaging demonstrated opacification of anterior ethmoid air cells adjacent to the region of the lacrimal sac. A greater awareness of this diagnostic possibility of pseudodacryocystitis arising from anterior ethmoiditis, together with improved noninvasive imaging techniques, will likely increase the observed incidence of this disease. This distinction is important since anterior ethmoidectomy, rather than dacryocystorhinostomy, is the treatment of choice when such pseudodacryocystitis proves unresponsive to antibiotic therapy. In misdiagnosed patients who undergo dacryocystorhinostomy, it is the coincidental limited anterior ethmoidectomy and not the lacrimal-nasal fistula that provides the cure.- - - - - - - - - - ranking = 10.040318508984keywords = dacryocystitis (Clic here for more details about this article) |
8/9. pseudomonas dacryoadenitis secondary to a lacrimal gland ductule stone.Infectious dacryoadenitis is a rare condition. A case of pseudomonas dacryoadenitis has not been reported previously. We treated a patient with pseudomonas dacryoadenitis secondary to obstruction from a lacrimal gland ductule stone. Histologically, the calculus contained hairs.- - - - - - - - - - ranking = 1.4keywords = dacryoadenitis (Clic here for more details about this article) |
9/9. An orbital abscess secondary to acute dacryocystitis.An orbital abscess is an ophthalmic surgical emergency that is typically caused by the spread of bacteria from adjacent structures, such as the sinuses, eyelids, or teeth. Although acute dacryocystitis is commonly associated with preseptal cellulitis, it rarely causes orbital infection. infection of the lacrimal sac will typically localize in the preseptal space because the lacrimal sac lies anterior to the orbital septum. To the authors' knowledge, this is the first report of an intraconal abscess secondary to acute dacryocystitis. The key points in the surgical management of this entity are discussed.- - - - - - - - - - ranking = 7.5302388817382keywords = dacryocystitis (Clic here for more details about this article) |
