Vulvo-vaginal myiasis among rural women in West Bengal, India

Myiasis, the infestation of living or dead tissue of vertebrates by larvae (maggots) of dipterous flies, is well-known in the medical field. Different parts of the human body, such as skin, oral, nasal, urogenital are affected and named accordingly. The present study was a clinic-entomological study where the women having vulvo-vaginal myiasis were included. Maggots were collected, cultured, and adult flies were identified. A total of 34 cases of vulvo-vaginal myiasis were treated. The larvae of 29 cases were cultured into adults. Most of the women are rural (94%), illiterate and from a low socioeconomic society. The authors specified the infested sites of vulva and vagina such as vaginal, labia, clitoris, episiotomy wound, vulval growth, and prolapsed uterus. The episiotomy wound (32%) is the most common infestation site, followed by the vagina (26%). Chrysomya bezziana (76%) and Chrysomya megacephala (24%) are the identified flies. Illiterate, rural puerperal mothers of low socioeconomic status without proper health education and basic hygiene knowledge are vulnerable to myiasis.

Myiasis Diagnosis and Treatment in Goat

Background: Myiasis is a disease caused by an infestation of fly larvae (Chrysomya bezziana) in living tissue. Myiasis cases are common in Indonesia because of the tropical climate. Purpose: This case report is intended to provide information on handling myiasis in goats. Case Analysis: A 2-year-old female goat weighing 30 kg was reported by the farmer because there was a wound in the leg. The goat was examined physically and hematologically. On physical examination, there was a limp on the left front leg caused by an injury with the larvae. Haematological examination results showed leukocytosis with leukocyte count of 13.26 x 103 cells/μL, monocytosis with monocyte counts of 0.63 x 103 cells/μL and anemia with erythrocyte counts of 2.93 x 106 cells/μL. The goat was diagnosed with myiasis and treated by eliminating fly larvae, irrigating the injured part by procaine penicillin and dihydrostreptomycin, spraying the wound using 1% dichlofenthion and intramuscular injection of 20 mg/kg body weight long-acting oxytetracycline and 1 mg/kg body weight diphenhydramine HCl. Conclusion: Three days after treatment, the wound condition has improved.

Otorhinolaryngological myiasis: the problem and its presentations in the weak and forgotten

Introduction: Myiasis is common in tropical regions, but now increasing incidence is seen in the west due to international travel. Otorhinolaryngological myiasis is uncommon and is seen in diabetics, alcoholics or patients unable in self-care.Objectives: To study presentations of otorhinolaryngological myiasis, identify associated risk factors and species of flies causing myiasis.Methods: Clinical findings and co-morbidities of 67 myiasis cases were noted. Maggots were identified, manually removed, and patients were managed with topical treatment, systemic ivermectin and antibiotics.Findings: Thirty-three nasal myiasis, 13 aural myiasis and 5 patients with oral myiasis were noted. Seven patients with head neck wounds myiasis and nine patients of tracheostome myiasis were recorded.Discussion: Warm humid climate of tropical regions is a major concern along with co-existing conditions like poor sanitation, alcoholism, psychiatric diseases and neuropathies. Hesitancy is seen in attendants and health care professionals to deal with myiasis.Conclusion: Awareness about risk factors is important in avoiding myiasis along with prompt treatment which reduces morbidity. Tracheostome myiasis is an under-documented entity rather than a rare presentation.Keywords: Myiasis, Ivermectin, screwworm, Chrysomya bezziana, Musca domestica, Lucilia sericata.Funding: None

MANAGEMENT OF ORAL MYIASIS CAUSED BY CHRYSOMYA BEZZIANA

Myiasis is derived from a Latin word ‘Muia,’ which means fly and ‘iasis,’ which means disease and a term derived from the Greek word “myia,” meaning invasion of fly larvae into vital tissue of humans or other mammals The term was coined by F.W. Hope in 1840
