A medical condition known as myiasis, or maggot infestation, occurs when fly larvae eat living tissue and continue to grow inside of it. Tropical and subtropical areas are where it is most commonly seen. Human myiasis is more prevalent among individuals who have close contact with domestic animals and those living in unhygienic conditions. Traumatic cerebral myiasis is a rare clinical condition in humans with only two such cases documented in the literature. It is brought on by a parasite infestation, also referred to as a maggot infestation of dipteran larvae, on an untended open wound due to trauma. In this report, we present an exceedingly rare case of cerebral myiasis in a 54-year-old Indian male, the first report from India, occurring as a result of trauma. Wound debridement with maggots removal and antibiotic administration was done. However, the patient was lost to follow-up.

Myiasis is defined as the infestation of any part of the body by fly larvae. It is particularly common in tropical and subtropical regions. Cutaneous myiasis is the most common manifestation of this infestation. Here, we report a 21-year-old Syrian female who presented with a 10-day history of painful 2 ulcer-like lesions on her scalp and was diagnosed with furuncular myiasis, which included more than 20 larvae. The patient had no history of international travel to myiasis-endemic areas before the onset of the lesions. She probably acquired the infestation while visiting a cattle farm located in a rural region east of Hama governorate. Seborrheic dermatitis developed on her scalp after the myiasis treatment was performed.

Chitinases play a crucial role in insect metamorphosis by facilitating chitin degradation. Sarcophaga peregrina (Robineau-Desvoidy, 1830) (Diptera: Sarcophagidae) is a typical holometabolous insect and an important hygiene pest that causes myiasis in humans and other mammals and acts as a vector for various parasitic agents, including bacteria, viruses, and parasites. Enhancing the understanding of the metamorphosis in this species has significance for vector control. In this study, we identified a total of 12 chitinase genes in S. peregrina using bioinformatic analysis methods. Based on transcriptome data, SpIDGF2 and SpCht10 were selected for further functional investigation. The down-regulation of these genes by RNA interference led to developmental delays, disruptions in molting, and differences in cuticle composition during the pupal stage. These findings underscore the pivotal role of chitinase genes in the metamorphic process and offer valuable insights for effective control strategies.

Myiasis is one of the most common skin diseases found in travelers returning from tropical and subtropical regions, where humans living in or visiting the African continent are most commonly infested by during the rainy season in regions with a warm climate. Here, we present a case of furuncular myiasis caused by in a Serbian patient returning from temporary work in Kenya, where the initial histology of skin lesion mimicked hyperproliferative skin disorder.

Myiasis is the invasion of mammalian tissues by dipterous larvae. Cutaneous myiasis is the commonest type, and less commonly, internal tissues and organs are affected. Here, we report the first case of oro-nasopharyngeal myiasis caused by the third-instar larvae of (Old-World screwworm) in Sri Lanka. A retired 71-year-old female tea-plucker presented to the hospital with a 4-day history of nasal bleeding and neck discomfort. Except for well-controlled hypertension, she had no significant medical history. On examination, there was an ulcerated area in the posterior oro-nasopharynx filled with maggots. Hematological analysis showed a high C-reactive protein level (24 mg/dL) and white blood cell count (17.5 × 10/L) with 80% neutrophils. Computed tomography showed severe inflammation of the pharynx with no features of a neoplasm or parapharyngeal abscess. An examination was performed under anesthesia followed by manual removal of larvae, surgical debridement with biopsy, and treatment with antiparasitic medicines and antibiotics. Histopathology excluded neoplasm and only showed inflammatory changes. All extracted larvae were morphologically similar and identified as third-instar larvae of using a trinocular zoom stereomicroscope. The patient recovered and was discharged from the hospital on the 15th day and was well at 2 months follow-up.

Myiasis is an ectoparasitic infestation caused by larvae of arthropods in the group Diptera. Cutaneous myiasis is the infection of skin and includes the following types: furuncular, migratory and wound myiasis. Out of all the organisms responsible for this disease, Wohlfahrtia vigil is the most common causative agent in Pakistan, usually seen from June to September with nearly all presentations occurring at a young age. In our case, a patient without a history of trauma, skin erosion or animal exposure has a unique presentation of cutaneous myiasis. Here, an effort was made to treat a 15- year-old otherwise healthy female with a multisegmented treatment modality. A follow up visit was conducted every three days for three months at the end of which a 60% decrease in the size of the open wound was observed.

Annals of Medicine and Surgery (2012) Oct 2023Myiasis of an open fracture wound is very rare but can occur due to neglect of wound care.
INTRODUCTION AND IMPORTANCE
Myiasis of an open fracture wound is very rare but can occur due to neglect of wound care.
CASE PRESENTATION
A 12-year-old boy from a low socio-economic background, following an impact injury in his right great toe 10 days back presented with complaints of pain, swelling, and a foul-smelling odor from his right great toe. On examination, a swollen, tender puncture wound was noted over the dorsal aspect of the great toe revealing part of live larvae and serosanguinous discharge. Management was done with the complete removal of maggots, wound debridement, wound lavage, administration of systemic antibiotics, and toe guard slab application.
CLINICAL DISCUSSION
Wound myiasis results from a facultative or obligatory parasite that is initiated when flies oviposit in hemorrhagic, necrotic, or pus-filled lesions. The possible complications of myiasis include local destruction, invasion into deep tissues, and secondary infection, which could result in amputation of the affected area, especially where obligatory parasites are concerned.
CONCLUSION
Myiasis commonly occurs due to poor hygiene and neglect of wound care along with many other risk factors. Early proper wound care prevents the development of wound myiasis and early diagnosis and treatment of myiasis prevent complication of local tissue destruction and amputation of affected parts.
