FIRST REPORT OF CANINE MYIASIS WITH SHEEP NASAL BOT FLY, Oestrus ovis, IN SLOVENIA

First larval stage (L1) of Oestrus ovis was recovered by flushing of the nasal cavity during rhinoscopy in an urban living dog. The dog was taken to the Small animal clinic after an acute onset of sneezing and bilateral nasal discharge. In Europe, there are sporadic reports of nasal myiasis in dogs caused by sheep bot flies, and the overall prevalence of O. ovis is high in Mediterranean countries. Because of its habitat expansion due to climate change, it should be considered as a differential diagnosis when an animal patient presents with signs of rhinitis in areas bordering the Mediterranean climate. This is the first report of a dog infested by sheep nasal bot fly in Slovenia.Key words: Oestrus ovis; sheep bot fly; nasal myiasis; dog; climate changesPRVI PRIMER PASJE MIAZE Z OVČJIM NOSNIM ZOLJEM, Oestrus ovis, V SLOVENIJIIzvleček: Med rinoskopijo in spiranjem nosne votline, smo pri psu, ki živi v urbanem okolju, ugotovili ličinke prve stopnje (L1) zajedavca Oestrus ovis. Lastniki so psa pripeljali na Kliniko za male živali po akutnem izbruhu kihanja in bilateralnega nosnega izcedka. V Evropi so dokumentirani sporadični primeri nosne miaze pri psih zaradi ovčjega nosnega zolja, O. ovis, in skupna prevalenca ovčjega zajedavca je v mediteranskih državah visoka. Zaradi klimatskih sprememb, se habitat nosnih zoljev čedalje bolj širi, za kar je pomembno O. ovis vključiti v seznam diferencialnih diagnoz pri pacientih s kliničnimi znaki rinitisa tudi na področjih, ki mejijo na mediteransko klimo. To je prvi opisan primer infestacije psa z ovčjim nosnim zoljem v Sloveniji.Ključne besede: Oestrus ovis; ovčja nosni zolj; nosna miaza; pes; podnebne spremembe

Nasal Maggot Infection in a Patient With Nasal Non-Hodgkin’s Lymphoma

We describe a case of nasal non-Hodgkin’s lymphoma in a 79-year-old Chinese patient accompany with nasal myiasis. The first 2 biopsies in this case were false negative. Subsequently, nasal maggots developed in this patient. After removing all maggots under nasal endoscopy, the patient continued to have recurrent fever and was transferred to a higher hospital for further treatment, in which he received a third biopsy. Unfortunately, several hours after the biopsy, the patient died for severe nasal bleeding. The final biopsy result indicated the neoplasm of the left nasal cavity was non-Hodgkin’s lymphoma. This case illustrates the importance of repeated biopsies for nasal non-Hodgkin’s lymphoma if necessary. Nasal myiasis is a secondary disease of nasal non-Hodgkin’s lymphoma in this case.

Nasal Myiasis: A Neglect State

Background: Nasal myiasis is a parasitic condition of human being and animal species in which nose and paranasal sinuses infested by Diptera Larvae of Chrysomya albiceps and Oestrus ovis group of flies. It is rare and sporadic, usually occurs in adults, the elderly, debilitated poor, and neglected patients suffering from chronic Sinonasal diseases. Methods: A cohort retrospective study of 11 cases in the Department of Otolaryngology and Head-Neck Surgery, Comilla Medical College Hospital, Cumilla, Bangladesh from 01 July 2016 to 31 June 2020. Results: Incidence of nasal myiasis out of total admitted in the inpatient department was 0.03%. Of them, the female was 10 (90.91%), the male 01 (9.09%) (P-value <0.001), age range 35-70 years, the adult was 09 (81.82%), and the elderly 02 (18.18%) (P-value <0.001). The left nostril exhibited 08 (72.73%), and right nostril 03 (27.27%) (P-value <0.05). Social class showed poor was 08 (72.73%), and lower middle class to working 03 (27.27%) (P value< 0.05), villagers was 09 (81.82%), and slum dwellers 02 (18.18%) (P-value <0.001), Sinonasal mass was 07 (63.64%), and atrophic rhinitis 04 (36.36%) (P-value <0.001), Sinonasal malignancy was 06 (85.71%), and benign 01 (14.29%) (P-value <0.001). Conservative traditional treatment was 07 (63.64%), and endoscopic removal 04 (36.36%) (P-value <0.001), recovery without complication was 10 (90.91%), and complication occurred in 01 (9.09%) (P value<.001). Conclusion: Nasal myiasis is a progression of other disease processes of the nose and paranasal sinuses of adults and the elderly in a low socioeconomic group of people. They need extra care medical services to overcome it.

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

Accidental Nasal Myiasis Caused by Megaselia rufipes (Diptera: Phoridae) in a Child

A case of a nasal myiasis in a 3-yr-old Italian girl who was referred to Bambino Gesù Hospital in Rome, Italy, is reported. Larvae discharged with the nasal mucus were microscopically identified as Megaselia spp.; DNA barcoding analysis showed that they belonged to the ‘scuttle fly’ species Megaselia rufipes (Meigen). Based on the patient’s history, she became infected when she played outside. This is the first report of myiasis in humans due to M. rufipes (Diptera: Phoridae).
