ABSTRACT

Chronic dacryocystitis is the inflammation of lacrimal sac, frequently caused by bacteria. Obstruction of nasolacrimal duct converts the lacrimal sac a reservoir of infection. It is a constant threat to cornea and orbital soft tissue. Moreover, it causes social embarrassment due to chronic watering from the eye. This study was conducted to find out the current clinicobacteriological profile of chronic dacryocystitis in adults. A total of 56 adult patients were selected from ophthalmology OPD. Detail history and clinical examinations were carried out. All patients underwent either dacryocystorhinostomy or dacryocystectomy. A part of the sac was collected for culture and sensitivity. This study revealed that chronic dacryocystitis is more common in females and left eye is more frequently involved than right eye. It is common among lower socioeconomic strata with habit of pond-bathing. Some form of nasal pathology like hypertrophied inferior turbinate, deviated nasal septum, nasal polyp and allergic rhinitis werefound in 19.6% of the patients. Complications of chronic dacryocystitis like conjunctivitis, corneal ulcer, acute on chronic dacryocystitis, lacrimal abscess and fistula were seen in 25.0% of these patients; 53.6% of the culture samples were positive for bacterial growth. Gram-positive organisms were most common isolate. Unlike other studies, Staphylococcus aureus (40.0%) was found to be most common Gram-positive organism, followed by Staphylococcus epidermidis (10.0%) and Steptococcus pneumoniae (10.0%). Among the Gram-negative organisms, Pseudomonas aeruginosa (16.6%) was the most common, followed by Klebsiella pneumoniae (6.6%) and Haemophilus influenzae (6.6%). Antibiotic sensitivity tests were done. Most of the organisms were resistant to penicillin. Chloramphenicol was effective against most of the Gram-positive organisms. Aminoglycosides, tobramycin in particular, was effective against Staphylococcus epidermidis. Fluoroquinolones, namely ciprofloxacin and ofloxacin were effective against Pseudomonas aeruginosa and Klebsiella pneumoniae.

ABSTRACT

An internal 24-hour biological clock working in tandem with external environmental cues like bright light regulates our daily rhythms specially sleep-wake cycle. In a blind individual, due to absence of external cue endogenous rhythm may take upper hand and free running of sleep-wake cycle starts without any synchronicity with day-night cycle, creating ground for sleep disorders. To evaluate the frequency of sleep disorders, 65 blind individuals without any comorbid medical or surgical problem were interviewed according to the criteria of Diagnostic and Statistical Manual of Mental Disorder-IV (DSM-IV). Simultaneously 70 persons with no visual impairment were assessed in the same manner as used for blind persons. Blind patients showed far higher presence (44.6%) of sleep problems compared to controls (15.7%), and this difference was highly significant statistically [odd's ratio (OR) = 4.32, CI 95 =1.8-10.54]. Blind patients showed far higher presence (43.1%) of DSM-IV based diagnosis compared to controls (8.6%), and this difference was highly significant statistically [OR = 8.072, CI 95 = 3.059-21.298]. Circadian sleep disorders, insomnia and hypersomnia were relatively higher in blind patients. High incidence of sleep disorders calls for development of short reliable screener for sleep disorders among blind persons and better liaison among ophthalmologists and psychiatrists for early detection of this problem.
