1/13. myiasis with Lund's fly (Cordylobia rodhaini) in travelers.myiasis is an infestation of human tissue by the larvae of certain flies. There are many forms of myiasis, including localized furuncular myiasis, creeping dermal myiasis and wound and body cavity myiasis.1 Cordylobia anthropophaga (the Tumbu fly) and Dermatobia hominis (the human botfly) are the most common causes of myiasis in africa and tropical America respectively. The genus Cordylobia also contains two less common species, C. ruandae and C. rodhaini. The usual hosts of C. rodhaini are various mammals (particularly rodents), and and humans are accidentally infested. Figure 1 shows the life cycle of C. rodhaini, which occurs over 55 to -67 days.3 The female fly deposits her eggs on dry sand polluted with the excrement of animals or on human clothing. In about 3 days, the larva is activated by the warm body of the host, hatches and invades the skin. As the larva matures, it induces a furuncular swelling. In 12 to -15 days, the larva reaches a length of about 23 mm, exits the skin and falls to the ground to pupate. The adult fly emerges in 23 to -26 days, and the life cycle resumes. In humans, the skin lesion starts as a red papule that gradually enlarges and develops into a furuncle. In the center of the lesion an opening forms, through which the larva breaths and discharges its serosanguinous feces. The lesion is associated with increasing pain until the larva exits the skin. The disease is usually uncomplicated and self-limiting.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
2/13. Internal ophthalmomyiasis presenting as endophthalmitis associated with an intraocular foreign body.Ophthalmomyiasis interna infestation by fly larva can present in various forms. A 3-year-old girl with a 15-day history of pain, redness, and tearing of the right eye was referred to our clinic with the diagnosis of endophthalmitis associated with an intraocular foreign body, based on clinical and ultrasonographic findings. The patient underwent pars plana vitrectomy, during which an 8-mm long larva was encountered within the vitreous cavity. It was removed and identified as a cattle botfly. The patient developed a retinal detachment 1 month postoperatively, but the family refused further treatment and the patient was lost to follow-up. Ophthalmomyiasis should be included in the differential diagnosis of endophthalmitis and intraocular foreign bodies in patients from rural areas.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
3/13. A case of oral myiasis due to Chrysomya bezziana.Chrysomya bezziana is a causative agent of obligatory myiasis. We report the first case of human infestation of Chrysomya bezziana in hong kong in an 89-year-old woman who had previously had a stroke. One day after hospital admission for fever, a small fissure at the labial gingiva of the upper incisors and several ulcerative lesions at the hard palate were noticed during routine mouth care. A live maggot was seen protruding from the small fissure. In the following few days, a total of seven maggots were removed by forceps. Urgent computed tomography and magnetic resonance imaging of the oral cavity showed an ulcerative soft-tissue lesion over the anterior palate, with a fistula communicating to the labial gingiva. The tissue loss was limited to the bony margin of the hard palate. The infestation was managed by manual removal of maggots and surgical debridement. Medical personnel taking care of old or debilitated patients need to bear in mind the possibility of Chrysomya bezziana infestation to be able to make a prompt diagnosis and implement relevant intervention to prevent extensive tissue destruction.- - - - - - - - - - ranking = 1.5103875697775keywords = cavity, mouth (Clic here for more details about this article) |
4/13. Radical mastoidectomy cavity myiasis caused by Wohlfahrtia magnifica.In this article, a Wohlfahrtia magnifica otomyiasis case, a 31-year-old, non-mentally retarded patient who had undergone radical mastoidectomy previously is presented. Maggots in the radical mastoidectomy cavity were removed then topical treatment was applied. The maggots were identified as W. magnifica. In cases of myiasis, identification of larvae following direct extraction and application of preventative methods is essential.- - - - - - - - - - ranking = 5keywords = cavity (Clic here for more details about this article) |
5/13. mastoid cells myiasis in a Saudi man: a case report.We report here the case of myiasis of the mastoid cells in a 50-year old Saudi farmer. Eight larvae of suspected Calliphorid fly were extracted from his right mastoid at examination in the clinic. The larvae almost ate into his brain, using their powerful screw-shaped mouth parts. It is the first report of Calliphorid larvae affecting the mastoid cells from saudi arabia. The epidemiological and clinical implications of this finding are discussed below.- - - - - - - - - - ranking = 0.51038756977753keywords = mouth (Clic here for more details about this article) |
6/13. Oral myiasis in a child by the reindeer warble fly larva Hypoderma tarandi.We describe a case of human oral myiasis by a first-stage larva of the reindeer warble fly, Hypoderma (Oedemagena) tarandi (L.) (diptera: Oestridae), in a 12-year-old girl. In September the patient complained of erythema, swelling and conjunctivitis of the right eyelid. Symptoms subsided spontaneously but re-occurred in October. In December she presented with acute swelling of the right corner of the mouth. Later that day a living larva protruded from this swelling. The patient had been on vacation in norway during the previous summer months.- - - - - - - - - - ranking = 0.51038756977753keywords = mouth (Clic here for more details about this article) |
7/13. Ophthalmomyiasis interna posterior.Ophthalmomyiasis interna posterior (OIP) means infection of the posterior part of the eye with the larvae of flies. Few cases have been reported in which the larvae have been removed from the eye and the visual acuity preserved. We report four cases of OIP with living larva in the vitreous cavity. The larvae produced severe uveitis and were removed alive with vitrectomy and a procedure for removing foreign bodies. They were identified as first-stage reindeer warble fly larvae (Oedemagena tarandi). We also observed dead larva in the vitreous cavity of a patient who suffered severe uveitis in 1943, and this eye survived with normal visual acuity. Another patient had a blind eye enucleated and the remnants of a larva were found inside the eye. All patients live in scandinavia.- - - - - - - - - - ranking = 2keywords = cavity (Clic here for more details about this article) |
8/13. Nosocomial nasal myiasis.Sixty-five fly maggots were retrieved from the nasal cavity of an unconscious 64-year-old man who had been admitted 18 days earlier with diabetic hyperosmolar coma. The larvae were identified as Cochliomyia macellaria, an organism commonly associated with myiasis in the united states. The clinical time sequence indicates that this infection was acquired in the hospital. This incident provides further evidence that immobile and debilitated patients are at risk to acquire myiasis.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
9/13. Lucilia sericata (diptera: Calliphoridae) causing hospital-acquired myiasis of a traumatic wound.A case of traumatic nosocomial myiasis caused by the green bottle fly Lucilia sericata (Meigen, 1826) occurred in a patient hospitalized following a serious road traffic accident. The patient had suffered extensive polytrauma particularly in the facial area of the skull. A total of 50 larvae was discovered in the oral cavity, nose, paranasal sinuses and enucleated eye-socket. Projected timing indicated that the eggs were laid while the patient was hospitalized. The development of myiasis was facilitated by the mental and physical debility and dependency of the patient, numerous and deep facial necrotic wounds and a lengthy period of hot weather which led to prolonged open window ventilation of his room.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
10/13. Neurofibromatosis with the eye fly Siphunculina funicola in an eyelid tumor.A 15-year-old Indonesian girl presented with a history of one year of multiple cutaneous tumors including a protuberant mass of the right upper eyelid. Histological findings were consistent with the clinical diagnosis of neurofibromatosis. A cystic cavity in the eyelid tumor contained the eye-fly Siphunculina funicola.- - - - - - - - - - ranking = 1keywords = cavity (Clic here for more details about this article) |
