Clinical Case (仍亳仆亳亠从亳亶 仍舒亶)
Abstract (从舒仍仆仂) Oral myiasis is a relatively rare pathology in humans caused by invasion of body tissue or cavities of living animals or humans by larvae of certain dipteran flies. It is an uncommon clinical condition, being more frequent in underdeveloped countries, and in countries with tropical climate. Common pre-disposing factors are poor oral hygiene, trauma, senility, suppurative oral lesions, and in patients with neuro-psychiatric deficits. 亅仂 仂仆仂亳亠仍仆仂 亠亟从舒 仗舒仂仍仂亞亳 , 于亰于舒仆仆舒 仗仂仆亳从仆仂于亠仆亳亠仄 于 从舒仆亳 亠仍舒 亢亳于仂仆 亳仍亳 仍ﾐ莞黍 仍亳亳仆仂从 仆亠从仂仂 亟于从仍 仄. 亅仂 从仍亳仆亳亠从仂亠 仂仂礌亳亠 弍仂仍亠亠 舒仂 于亠舒亠 于 仍舒弍仂舒亰于亳 舒仆舒, 亳 于 舒仆舒 仂仗亳亠从亳仄 从仍亳仄舒仂仄. 弍亳亠 仗亠亟舒仗仂仍舒亞舒ﾑ亳亠 舒从仂: 仗仍仂舒 亞亳亞亳亠仆舒 仗仂仍仂亳 舒, 舒于仄, 仄舒舒亰仄, 亞仆仂亶仆亠 仗仂舒亢亠仆亳 仂仂于仂亶 仗仂仍仂亳, 仗舒亳亠仆 仗亳亳亠从亳仄亳 亰舒弍仂仍亠于舒仆亳礆亳.
Epidemiology (仗亳亟亠仄亳仂仍仂亞亳) Low socioeconomic status, immunocompromised state, debilitated and unhygienic living conditions are the main contributing factors responsible for myiasis. The risk factors for oral myiasis include suppurative lesions, facial trauma, mouth-breathers, extraction wounds, fungating carcinomas and others conditions. The species was first found in animal wounds in Hong Kong in the year 2000. The first case in humans was documented in 2003 in Hong Kong. Chrysomya bezziana is widely distributed throughout Asia, including China and neighboring regions of Hong Kong, such as Guangdong, Guangxi, Yunnan and Taiwan. It is also found in tropical Africa and Papua New Guinea. 亳亰从亳亶 仂亳舒仍仆仂-从仂仆仂仄亳亠从亳亶 舒, 仍亳舒 仂仍舒弍仍亠仆仆仄 亳仄仄仆亳亠仂仄 , 舒仆亳舒仆亳舒仆亠 仍仂于亳 仗仂亢亳于舒仆亳 磦仍ﾑ 仂仆仂于仆仄亳 舒从仂舒仄亳, 仗仂仂弍于ﾑ亳亠 舒亰于亳亳 仄亶舒亳舒. 个舒从仂 亳从舒 亟仍 仗亠仂舒仍仆仂亞仂 仄亶舒亳舒 :亞仆仂亶仆 仗仂舒亢亠仆亳亶, 舒于仄 仍亳舒, 仗仂仍亠仂仗亠舒亳仂仆仆亠 舒仆, 舒从 亳 亟亞亳亠 仍仂于亳. 舒仆仆仂亠 亰舒弍仂仍亠于舒仆亳亠 弍仍仂 于仗亠于亠 仂弍仆舒亢亠仆仂 于 舒仆亠 亢亳于仂仆 于 仂仆从仂仆亞亠 于 2000 亞仂亟. 亠于亶 仍舒亶 亠仍仂于亠从舒 弍仍 亰舒亠亞亳亳仂于舒仆 于 2003 亞仂亟 于 仂仆从仂仆亞亠.

Causes (亅亳仂仍仂亞亳) Cases of oral myiasis have been reported to occur following dental extraction, nosocomial infection, in drug addicts, in psychiatric patients, and conditions that are likely to cause prolonged mouth opening such as mouth breathing during sleep, senility, alcoholism, and mental retardation. Other pre-disposing factors are incompetent lips, poor oral hygiene, severe halitosis, anterior open bite, facial trauma, extraction wounds, ulcerative lesions, and carcinoma. 仂舒亢亠仆亳亠 仗仂仍仂亳 舒 仄舒亶舒亳仂仄, 仗仂 亟舒仆仆仄 仍亳亠舒, 仗仂亳仂亟亳 于 亠亰仍舒亠 仗亳仂亠亟亳仆亠仆亳 于仂亳仆仂亶 亳仆亠从亳亳 仗仂仍亠 亟舒仍亠仆亳 亰弍仂于, 于仆亳弍仂仍仆亳仆仂亶 亳仆亠从亳亳, 仆舒从仂仄舒仆仂于, 仗舒亳亠仆仂于 仗亳亳舒亳亠从亳仄亳 舒仂亶于舒仄亳, 亳 仍仂于亳, 从仂仂亠 仄仂亞 仗亳于亠亳 从 亟仍亳亠仍仆仂仄 仂从于舒仆亳 舒 (仆舒仗亳仄亠, 亟舒仆亳亠 亠亠亰 仂 于仂 于亠仄 仆舒), 仗舒亳亠仆仂于 ,舒亟舒ﾑ亳 舒仍从仂亞仂仍亳亰仄仂仄 亳 仄于亠仆仆仂亶 仂舒仍仂. 亞亳亠 仗亠亟舒仗仂仍舒亞舒ﾑ亳亠 舒从仂: 舒仆舒仂仄亳亠从亳亠 仂仂弍亠仆仆仂亳 仂亠仆亳 亞弍, 仗仍仂舒 亞亳亞亳亠仆舒 仗仂仍仂亳 舒, 仂从亶 仗亳从, 舒于仄 仍亳舒, 磶于亠仆仆亠 仗仂舒亢亠仆亳 亳 舒从.
Primary myiasis is caused by biophagous larvae (feed on living tissues) and also as obligatory myiasis. Secondary myiasis is caused by necrobiophagus larvae (feed on dead tissues) and also called as facultative myiasis. The most anatomical sites for myiasis are the nose, eyes, skin wounds, sinuses, ears, lungs, gut, gall bladder, vagina, nasal cavities, and rarely, the mouth. 亠于亳仆亶 仄舒亶舒亳 于亰于舒亠 亳仂舒亞仆仄亳 仍亳亳仆从舒仄亳 (仗亳舒ﾑ亳仄亳 亢亳于仄亳 从舒仆礆亳), 舒 舒从亢亠 于 从舒亠于亠 仂弍仍亳亞舒仆仂亞仂 仄亶舒亳舒. 仂亳仆亶 仄亶舒亳 于亰于舒亠 亠从仂弍亳仂舒亞仆仄亳 仍亳亳仆从舒仄亳 (仗亳舒ﾑ 仄亠于仄亳 从舒仆礆亳) 亳 舒从亢亠 于 亠亰仍舒亠 舒从仍舒亳于仆仂亞仂 仄亶舒亳舒. 舒亳弍仂仍亠亠 舒仄亳 仍仂从舒仍亳亰舒亳礆亳 亟仍 仄亶舒亳舒 磦仍ﾑ 仆仂, 亞仍舒亰舒, 从仂亢仆亠 舒仆, 仗舒亰亳, 亳, 仍亠亞从亳亠, 从亳亠仆亳从, 亢亠仍仆亶 仗亰, 于仍舒亞舒仍亳亠, 仗仂仍仂亳 仆仂舒, 亳 亠亟从仂, 仗仂仍仂 舒.
Pathogenesis (仗舒仂亞亠仆亠亰) The adult female lays eggs on live mammals. The sites of infestation are usually superficial wounds, open sores and mucous membranes in body orifices such as the mouth, ear and nose. The eggs hatch within 24 h and the resulting larvae burrow into the hosts tissues head- downwards into the wound in a characteristic screw-like fashion, feeding on living tissue. The larvae release toxins to destroy the host tissue. Proteolytic enzymes released by the surrounding bacteria decompose the tissue on which the larvae feed. The larvae complete their development in 57 days. They then wriggle out of the wound and fall to the ground to pupate.

The area was then washed with saline, followed by irrigation with betadine. Broad spectrum antibiotics amoxycillin with clavaualnic acid and ibuprofen with paracetamol were prescribed.
