BACKGROUND
A young boy presented with acute ethmoiditis and recurrent periorbital swelling. The periorbital swelling was confirmed to be caused by a rare condition.
CASE PRESENTATION
Debut symptoms were acute rhinitis, unilateral periorbital swelling, fatigue, and swelling in the temple region, probably caused by an insect bite. Magnetic resonance imaging (MRI) of the sinuses showed bilateral ethmoiditis and unilateral periorbital cellulitis without subperiostal abscess formation, and antibiotics were prescribed. Because of recurrence of the periorbital swelling, an interdisciplinary team started an investigation for a differential diagnosis. The infestation of Hypoderma tarandi was confirmed by recent history of hiking in reindeer habitat, typical clinical presentation and detection of IgG hypodermin C antibodies.
INTERPRETATION
Human myiasis by Hypoderma tarandi is a rare condition in Norway. Typical clinical signs are unaffected general condition, migration of swelling in the forehead, recurrent unilateral periorbital swelling and normal CRP levels. Early-stage diagnosis and treatment will contribute to rapid symptom relief and prevent rare eye and intracranial complications. This case illustrates the importance of investigation for other conditions when the disease course is unexpected. The authors emphasise that knowledge about this disease is important in a variety of medical specialties.

The infestation of the human body by maggots has been reported worldwide and occurs most commonly in people of lower socioeconomic status and poor personal hygiene. Urogenital is the rarest site of myiasis presentations. Here we report the case of a 20-year-old, sexually inactive female student who presented with a necrotic growth in the paraurethral region infested with numerous maggots. The lesion involved the urethra and the bladder base. She was treated with debridement and bladder irrigation. The cystoscopy and local examination performed 2 weeks after admission, confirmed the complete healing of the urogenital lesion. Managing this patient's unique challenge was to assess the extent of the involvement and removal of all maggots from the deepest wound portion. The female internal and external urogenital myiasis is a very occasional and under-reported health hazard. Reporting such cases increases the public and physician awareness about the mode of presentation, right diagnosis, and available treatment options.

BACKGROUND
Human myiasis is a parasitic dipteran fly infestation that infects humans and vertebrates worldwide. However, the disease is endemic in Sub-Saharan Africa and Latin America. In Sub-Saharan Africa, it is under-reported and therefore its prevalence is unknown. This systematic review aims to elucidate the prevalence of human myiasis, factors that influence the infection, and myiasis-causing fly species in SSA. The review also dwelled on the common myiasis types and treatment methods of human myiasis.
METHODS
Here, we collect cases of human myiasis in Sub-Saharan Africa based on literature retrieved from PubMed, Google Scholar and Science Direct from 1959 to 2022. A total of 75 articles and 157 cases were included in the study. The recommendations of PRISMA 2020 were used for the realization of this systematic review.
RESULTS
In total, 157 cases of human myiasis in SSA were reviewed. Eleven fly species (Cordylobia anthropophaga, Cordylobia rodhaini, Dermatobia hominis, Lucilia cuprina, Lucilia sericata, Oestrus ovis, Sarcophaga spp., Sarcophaga nodosa, Chrysomya megacephala, Chrysomya chloropyga and Clogmia albipuntum) were found to cause human myiasis in SSA. Cordylobia anthropophaga was the most prevalent myiasis-causing species of the reported cases (n = 104, 66.2%). More than half of the reported cases were from travelers returning from SSA (n = 122, 77.7%). Cutaneous myiasis was the most common clinical presentation of the disease (n = 86, 54.7%). Females were more infected (n = 78, 49.6%) than males, and there was a higher infestation in adults than young children.
CONCLUSION
The findings of this study reveals that international travelers to Sub-Saharan Africa were mostly infested therefore, we recommend that both international travelers and natives of SSA be enlightened by public health officers about the disease and its risk factors at entry points in SSA and the community level respectively. Clinicians in Sub-Saharan Africa often misdiagnose the disease and most of them lack the expertise to properly identify larvae, so we recommend the extensive use of molecular identification methods instead.

Review
Myiasis is a type of parasitosis caused by the larvae of diptera. It commonly occurs in tropical and subtropical zones. The infestation of nose and ears can be extremely dangerous if the larvae destroy the bone and penetrate into the brain, in which case the fatality rate is reported to be as high as 8%. Here, we report a case of aural myiasis in a patient with congenital mental retardation. Twelve maggots were removed mechanically, and the patient was treated with appropriate antibiotics.

BACKGROUND
Nasal myiasis is a nasal infestation caused by house fly larvae (maggot). It's a rare condition with only a few reported cases and no treatment consensus.
CASE PRESENTATION
A 54-year-old woman was admitted to the emergency unit with a complaint of larvae found in the left nasal cavity and bloody nasal discharge for 2 days. Anterior rhinoscopy found some living larvae in a narrowed left nasal cavity. Patient's management included larvae removal manually with forceps, nasal saline irrigation, a systemic broad-spectrum antibiotic, and insulin to controlled blood sugar.
DISCUSSION
Removal of larvae in the nasal cavity using irrigation saline and systemic broad-spectrum antibiotics is effective in the absence of bone destruction.
CONCLUSION
manual extraction combined with nasal saline irrigation and systemic broad-spectrum antibiotic was effective to manage nasal myiasis.

BACKGROUND
Myiasis is an emerging disease caused by tissue invasion of dipteran larvae. In Uruguay, Cochliomyia hominivorax and Dermatobia hominis are the most frequent species. This study aimed to describe the epidemiological and clinical characteristics and the follow-up of children < 15 years hospitalized for myiasis in a reference center in Uruguay between 2010 and 2019.
METHODS
We conducted a descriptive and retrospective study by reviewing medical records. We analyzed the following variables: age, sex, comorbidities, origin, the month at admission, clinical manifestations, other parasitoses, treatments, complications, and larva species identified.
RESULTS
We found 63 hospitalized children: median age of 7 years (1 month-14 years), 68% of females. We detected risk comorbidities for myiasis (33%), of which chronic malnutrition was the most frequent (n = 6); 84% were from the south of the country; 76% were hospitalized during the summer. Superficial and multiple cutaneous involvements were found in 86%: of the scalp 50, furunculoid type 51, secondary to C. hominivorax 98.4%, and to D. hominis in 1.6%. As treatments, larval extraction was detected in all of them, surgical in 22%. Asphaltic products for parasites were applied in 94%, ether in 49. Antimicrobials were prescribed in 95%; cephradine and ivermectin were the most frequent. About 51% presented infectious complications, impetigo was found in 29, cellulitis in 2, and abscess in 1.
CONCLUSIONS
Myiasis predominantly affected healthy schoolchildren during the summer months and was frequently associated with ectoparasites. Superficial infestation of the furuncle-like scalp by C. hominivorax was the most frequent form. Infectious complications motivated hospitalizations.

Giant otters are territorial semi-aquatic mammals. It is common to find several individuals exhibiting wounds and scars due to intraspecific conflicts. Myiasis is a parasitic infestation on living tissues of vertebrates caused by dipterous larvae, that usually develops in freshly open wounds and can seriously threaten the host's health. Ectoparasites seem to be rare among giant otters and myiasis had not been recorded in this species until now. Here, is presented one record of myiasis in a free-ranging giant otter found dead in the Pantanal, Brazil. An ulcerative lesion was found in the frontoparietal region, from which 22 larvae were recovered and identified as Cochliomyia hominivorax. The low occurrence of ectoparasites in giant otters might reflect their semi-aquatic habits and their grooming behavior, which makes it difficult for parasites to remain on the skin. The injured otter probably got the larvae after an intraspecific fight. Agonistic encounters between groups of giant otters have been reported before and these fights can result in serious wounds or even death. It was hypothesized that the myiasis caused by C. hominivorax deteriorated the health of the infested giant otter, which prevented recovery and accelerated its death.
