1/3. Ophthalmomyiasis and nasal myiasis in new zealand: a case series.We report three cases of ophthalmomyiasis in new zealand, due to the larvae of Oestrus ovis. All three patients reported eye injury caused by a fly. The larvae were removed from the conjunctival sac without difficulty under local anaesthesia. Presenting ocular symptoms of foreign body sensation, irritation, redness and photophobia all resolved swiftly. Topical antibiotic and steroid eye drops were administered. All three patients also developed nasal symptoms such as sneezing, nasal discharge and epistaxis. otolaryngology follow-up demonstrated nasal myiasis in two patients which was treated with nasal decongestants. In addition, all three patients were treated with ivermectin (Mectizan).- - - - - - - - - - ranking = 1keywords = anaesthesia (Clic here for more details about this article) |
2/3. External ophthalmomyiasis caused by Dermatobia hominis. A retrospective study of nine cases and a review of the literature.PURPOSE: To report nine cases of external ophthalmomyiasis caused by Dermatobia hominis. methods: Retrospective, non-comparative, interventional case series. Participants consisted of patients (n = 9) presenting at Cayenne Hospital between 1968 and 2003. The location and number of larvae, the larval stage, and the medical and surgical procedures applied were studied in each case. RESULTS: Seven patients had palpebral myiasis (including one with three larvae) and two had conjunctival myiasis. Every patient had palpebral oedema. The larval respiratory pore was located on the palpebral skin or free margin or on the conjunctiva. Movements were present within the lesion in at least three patients. petroleum ointment or ivermectine solution was used in at least four patients to smother or kill the larvae. Extraction under local anaesthesia was possible in six patients, while three required general anaesthesia. CONCLUSION: Several larvae may be present in a patient. Topical ivermectine may help to kill the larvae before extraction is attempted.- - - - - - - - - - ranking = 2keywords = anaesthesia (Clic here for more details about this article) |
3/3. First report of ophthalmomyaisis externa in pakistan.Two individuals presented to the Aga Khan University Opthalmology service with foreign-body sensation, pain and redness in one of their eyes. Slit-lamp biomicroscopy revealed tiny larvae crawling around the conjunctival sac. They were mechanically removed under topical anaesthesia and preserved for light microscopy and photography. Comprehensive liaison was established with the Australian Centre for International agriculture research for identification of these larvae. Their morphology characterized them as members of fruit-fly, Oestridae family. At least one of them was positively identified as first instar larva of Oestrus ovis. This report describes the first instance of such infections in Southern pakistan, as concluded after a medline search.- - - - - - - - - - ranking = 1keywords = anaesthesia (Clic here for more details about this article) |
