1/6. Phthiriasis palpebrarum: an unusual blepharoconjunctivitis.Phthiriasis palpebrarum is an unusual cause of blepharoconjunctivitis and may easily be overlooked because of the failure of physicians to recognize phthirus pubis. We report a case of a 30-year-old woman with persistent itching in the left eyelid which was unsuccessfully treated under the diagnosis of allergic blepharoconjunctivitis. Careful ophthalmic examination revealed seven bugs with multiple red pinpoint excretions and numerous small translucent oval eggs (nits) coating the eyelashes. The patient was successfully treated with mechanical removal of all the lice and nits from the eyelashes. The specimen proved histopathologically to be the phthirus pubis infestation. The phthirus pubis infestation is usually associated with poor hygiene in overcrowded or undeveloped country. However, it may become a notable problem because of frequent traveling and commercial activities across the different countries.- - - - - - - - - - ranking = 1keywords = infestation (Clic here for more details about this article) |
2/6. Ophthalmomyiasis caused by the sheep bot fly Oestrus ovis in northern iraq.myiasis is the feeding of fly larvae on vertebrates. The sheep bot fly larva of Oestrus ovis is a mammalian parasite of the skin, nose, ears, and eyes. When the larvae infest and feed on the structures of the eye, the condition is termed ophthalmomyiasis. Most often this infestation is limited to the external structures of the eye and is referred to as ophthalmomyiasis externa. The features of this condition are severe local inflammation, positive foreign body sensation, erythema, and lacrimation. Vision may or may not be reduced, depending on involvement of the cornea. A 20-year-old white male soldier sought treatment for an inflamed eye and an irritated cornea OS. His eyelids were swollen with marked periorbital edema and conjunctival erythema OS. On slitlamp examination, small whitish organisms were viewed on the conjunctiva OS. The organisms were removed, preserved, and sent to Nova Southeastern University where they were identified as O. ovis first-stage larvae. The patient was treated with antibiotic ointment, and the inflammation resolved within 1 week. O. ovis has a worldwide distribution, and although sheep are the preferred host, humans may also serve as an intermediate host in the organism's life cycle. This case represents one of several reports of ophthalmomyiasis in the middle east caused by O. ovis. U.S. troops stationed in iraq and surrounding areas are vulnerable to eye infestation by fly larvae, and health care providers need to include this condition in their differential diagnosis of anterior segment inflammatory disorders.- - - - - - - - - - ranking = 1.1354839993903keywords = infestation, mite (Clic here for more details about this article) |
3/6. Periocular inflammation after retrobulbar chlorpromazine (thorazine) injection.PURPOSE: Retrobulbar chlorpromazine injection is a relatively recently described method of pain control in nonseeing eyes. This report illustrates severe sterile inflammation as a potential complication. methods: In this university-based, retrospective, small case series, we reviewed the records of 2 female patients and 1 male patient (ages, 13 to 89 years) who developed severe inflammation after retrobulbar chlorpromazine injection. RESULTS: Three patients had development of severe periocular edema after retrobulbar chlorpromazine injection. Two had development of chemosis, limited extraocular motility, proptosis, and incomplete eyelid closure, necessitating temporary tarsorrhaphy. The third patient had development of facial edema involving the ipsilateral eyelids, forehead, and cheek. Strikingly, it extended to the contralateral face. All 3 patients denied discomfort. In each case, swelling was first noted the day after injection and progressed for 1 week. All were treated with topical lubrication and two with temporary tarsorrhaphy. Resolution occurred within 3 weeks in each case. CONCLUSIONS: Severe periocular inflammation can result from retrobulbar chlorpromazine injection and may manifest as chemosis, proptosis, limited ocular motility, and facial swelling that may extend well beyond the eyelids. awareness of this potential adverse reaction is important both for patient counseling before injection and subsequent treatment. Specifically, a sterile inflammatory response should be differentiated from infection to avoid inappropriate therapy.- - - - - - - - - - ranking = 0.27096799878057keywords = mite (Clic here for more details about this article) |
4/6. A case report of demodicosis.We report on a patient who had an excessive number of mites (Demodex folliculorum) on his eye lashes, i.e. 10 mites on eight lashes examined. A review of three previous reports suggested that one mite for every two lashes represents an over population of this nearly ubiquitous mite. Greasy scales on the lashes and foamy tears suggested that seborrhea was present as well as demodicosis. The primary symptoms of itching was relieved after one week of treatment with mercuric oxide ointment and lid scrubs, although the number of mites was not reduced. Treatment for an additional two weeks did reduce the mite number. We therefore recommend continuing treatment for demodicosis for at least three weeks even if symptoms abate sooner.- - - - - - - - - - ranking = 0.81290399634172keywords = mite (Clic here for more details about this article) |
5/6. Pediatric ocular phthiriasis infestation.Although pubic lice infestation of ocular regions is relatively uncommon, the optometrist needs to be aware of the diagnosis and treatment of louse-infested patients. A case report of ocular phthiriasis is presented along with a discussion of its etiology, clinical diagnosis and management.- - - - - - - - - - ranking = 2.5keywords = infestation (Clic here for more details about this article) |
6/6. Diagnosing and treating phthirus pubis palpebrarum.Phthiriasis palpebrarum is an uncommon cause of blepharitis and conjunctivitis and may easily be overlooked. A high index of suspicion and careful examination of the patient's lid margins and eyelashes will lead to the proper diagnosis. Treatment is best accomplished by careful removal of the lice and nits (louse eggs) from the patient's lashes. Local application of a pediculocide such as yellow mercuric oxide N.F. 1% ophthalmic ointment applied twice daily for one week or 0.25% physostigmine (Eserine) ointment applied twice daily for a minimum of ten days, to the lid margins should be considered when the total removal of phthirus pubis and nits is not possible mechanically. Body hair should be examined for infestation with lice and treated with gamma benzene hexachloride shampoo. This medication should be used with caution in infants, children and pregnant women. family members, sexual contacts, and close companions should be examined and treated appropriately; clothing, linen and personal items should be disinfected with heat of 50 degrees C for 30 minutes.- - - - - - - - - - ranking = 0.5keywords = infestation (Clic here for more details about this article) |
