RESUMO

In this article, we intend to discuss a case of cutaneous myiasis in a British child traveller who recently travelled to Somaliland. A Cordylobia anthropophaga larva was identified as the species that caused the disease. The case report, which contains a video illustration of the causative agent, proved a diagnostic challenge at presentation.

RESUMO

Myiasis by Oestrus ovis, the zoonotic infestation with Diptera larvae, primarily diagnosed in goats and rams in tropical and Mediterranean countries, is an uncommon disease in humans; indeed, literature data are still lacking. Nevertheless, few cases of human myiasis have been reported, leading to benign or severe complications. Here, we report a rare case of human rhinomyiasis detected in Northern Italy. A 39-year-old Italian woman, returning from vacation in Corsica, showed several sinusal symptoms and progressive asthenia and was therefore admitted at the Otorhinolaryngology Unit of Biella Hospital, Italy. Endoscopic examination of the nasal cavity revealed some formations, morphologically identified as O. ovis larvae. The patient then underwent endoscopic sinus surgery, followed by complete resolution of symptoms. Clinical presentation, diagnostic work-up and therapeutic procedures have been compared with few other cases found in the literature.

RESUMO

The work deals with atypical conjunctival infection of Czech patient with Oestrus ovis larvae. Ophthalmomyiasis is infestation of mammalian eyes by the larvae or worms of some flies. The most common cause of human myiasis is the Sheep. Shepherds are infected in habitats, but human eye disease outside the areas of abundant hamsters is rare. We describe a case of eye disease in a middle-aged man from the Czech Republic who spent a summer holiday seven weeks before examination in the north of Greece. During the first examination he was completely treated and no further problems were reported. Ophthalmomyiasis externa should be considered as a possible infection of travelers to the southern endemic regions when returning with an acute causeless onset of a one-sided foreign body sensation in the eye.

RESUMO

Myiasis is defined as follows; some flies lay their eggs and larvae on live organs and tissues or on cavities of nose, eye, ear and etc of humans or animals and the larvae develop there and cause pathological disorders. One of the rare types of myiasis is the urogenital myiasis. This condition has been associated with covering urogenital area with clothes in almost all populations and therefore, less chance for flies to reach this site and lay their eggs. Low socio-cultural level and poor hygiene conditions are stated as the most important risk factors of myiasis. On the other hand, toilets within the human living spaces are ideal environments for fly larvae that are fed on bacteria as they contain moisture and a microbial environment. It is stated that especially in case of the presence of an underlying infection, flies are more prone to lay their eggs or larvae on this area due to the bad smell. In this case report, a patient with a moderate sociocultural level with no underlying chronic disease, no open wound in the genital area and no urinary tract infection was presented. A 53-year-old female patient living with her family in an apartment flat in the city center of Konya admitted to the outpatient clinic of infectious diseases with the complaint of moving worms in her urine. The patient stated that she had seen maggots while urinating for two weeks and that she passed her urine into a container to be sure that the maggots were coming from her urine, upon seeing the maggots there she has admitted to the hospital. The Larvae were defined as the fourth stage larvae of Psychoda spp. No open lesions or wounds were seen in genitourinary area of the patient who had no complaints other than mild urinary burning. Complete blood count test results of the patient were normal and there was no growth in her urine culture. It was stated that other family members whom she lived with did not have similar complaints. The patient was diagnosed as genitourinary myiasis caused byPsychoda spp. and informed about the relationship between hygiene and the disease. And urinary antiseptics were initiated as the treatment for the patient. After the treatment, no larvae were seen in the urine of the patient. In conclusion, many regions are suitable for Psychoda type of adult flies to live in our country due to the climate conditions. It is considered that infestation may develop in patients with less risk factors in terms of urogenital myiasis, that larvae may increase in number of patients who are not treated or followed up and that the infestation may become chronic and results in more serious clinical conditions. The necessary treatment and follow-up must be performed in such cases and the patients should be educated about the relationship between infestation and hygiene.

RESUMO

INTRODUCTION: Parasitic infections of the eye are a major cause of ocular-surface diseases globally. While most infections are treatable, parasites can cause varying levels of damage mostly due to late diagnosis or misdiagnosis as a result of doctors' unfamiliarity with their characteristics of latency and crypsis, as well as lack of awareness by the patients. CASE REPORTS: In this study, we present three cases of phthiriasis palpebrarum, thelaziasis, and ophthalmomyiasis, respectively. Two of the cases were treated at the clinic and did not recur. One patient refused treatment and was lost to follow-up. DISCUSSION: By evaluating the natural histories, morphology, symptoms, clinical findings, and treatment of these parasitic diseases, we systematically analyzed several distinct and unique parasite characteristics, especially latency and crypsis. Furthermore, we have proposed specific examination techniques and methods as well as prevention and treatment strategies from these specific perspectives, aiming to prompt timely diagnoses and early interventions for these diseases by health care workers and improve the public's awareness of parasitic infections. CONCLUSION: Parasitosis on the ocular surface is a global infectious disease, and prevention strategies include maintaining personal and environmental hygiene and limiting contact with animals. We recommend that health care workers should enhance their ability to detect and diagnose these diseases while promoting the public's awareness of them in the context of our new perspectives.

RESUMO

We review epidemiological and clinical data on human myiasis from Ecuador, based on data from the Ministry of Public Health (MPH) and a review of the available literature for clinical cases. The larvae of four flies, Dermatobia hominis, Cochliomyia hominivorax, Sarcophaga haemorrhoidalis, and Lucilia eximia, were identified as the causative agents in 39 reported clinical cases. The obligate D. hominis, causing furuncular lesions, caused 17 (43.5%) cases distributed along the tropical Pacific coast and the Amazon regions. The facultative C. hominivorax was identified in 15 (38%) clinical cases, infesting wound and cavitary lesions including orbital, nasal, aural and vaginal, and occurred in both subtropical and Andean regions. C. hominivorax was also identified in a nosocomial hospital-acquired wound. Single infestations were reported for S. haemorrhoidalis and L. eximia. Of the 39 clinical cases, 8 (21%) occurred in tourists. Ivermectin, when it became available, was used to treat furuncular, wound, and cavitary lesions successfully. MPH data for 2013-2015 registered 2,187 cases of which 54% were reported in men; 46% occurred in the tropical Pacific coast, 30% in the temperate Andes, 24% in the tropical Amazon, and 0.2% in the Galapagos Islands. The highest annual incidence was reported in the Amazon (23 cases/100,000 population), followed by Coast (5.1/100,000) and Andes (4.7/100,000). Human myiasis is a neglected and understudied ectoparasitic infestation, being endemic in both temperate and tropical regions of Ecuador. Improved education and awareness among populations living in, visitors to, and health personnel working in high-risk regions, is required for improved epidemiological surveillance, prevention, and correct diagnosis and treatment.

RESUMO

RATIONALE: Myiasis is a parasitic disease caused by fly larvae of the Diptera order that infest human and other vertebrate animal tissues. Orbital myiasis is a potentially destructive infestation of the orbital tissues, which may affect individuals with previous ocular diseases or disorders of consciousness. PATIENT CONCERNS: A 72-year-old man presented with a complaint of repeated pain for two years after trauma to his right eyelid and aggravated symptoms with larvae wriggling out for 2 days. An orbital computed tomography scan revealed right eyeball protrusion and periocular soft tissue edema. Two days later, magnetic resonance imaging showed that the shape of the right eyeball was changed and that the normal structure of the eyeball could not be identified. DIAGNOSES: Due to the patient's symptoms and imaging examination results, the diagnosis of orbital myiasis was made. INTERVENTIONS: The patient was treated by exenteration of the right orbit, and all necrotic tissues and larvae were removed. The defect was repaired via reconstruction with a pedicled musculocutaneous flap from the forehead region. Antibiotics and tetanus toxoid therapy were utilized to prevent potential bacterial infection. OUTCOMES: The patient recovered well postoperatively and was discharged uneventfully. During the 6-month follow-up period, the wound healed well. LESSONS: Advanced age and untreated eye trauma are risk factors for orbital myiasis. Timely removal of larvae and elimination of infections are important measures for protecting the eyeball.

RESUMO

We describe a case of nasal myiasis in an 89-year-old Brazilian patient affected by leprosy with severe nasal sequelae. An initial treatment comprising sinusectomy combined with nasal endoscopy removed more than 300 larvae, supplemented by systemic treatment using oral and topical ivermectin and levofloxacin. Infestation recurred after 2 months, was treated similarly, and resolved completely. The case could be attributed to severe nasal leprosy sequelae, with a lack of sneezing reflex, painless ulceration, atrophic rhinitis (ozena), and inability to clean the nose properly due to hand and nose impairment. This case illustrates the importance of long-term medical follow-up of patients with leprosy sequelae.

RESUMO

This is the first case report in Egypt and Middle East region of human intestinal myiasis caused by Clogmia albipunctata larvae. A 36-year-old male patient presented to the Outpatient Clinic of Internal Medicine in Beni-Suef University Hospital complaining of abdominal pain, bloating, and diarrhea intermittent with constipation. Patient's stool sample was referred to the Department of Medical Parasitology for examination of passed larvae and treatment prescription. Examination of larvae by light and scanning electron microscopy confirmed the morphological identification of fourth instar larvae of C. albipunctata. Human intestinal myiasis is an unusual cause of gastrointestinal manifestations.

RESUMO

The objective of the present study is to present a patient with oral myiasis caused by Calliphoridae larvae. The patient was a 63-year-old male who was transferred from Van Closed Prison to Yüzüncü Yil University, Faculty of Medicine Research and Application Hospital. Five alive larvae localized in different points of gingival region were observed during routine oral cleaning. These larvae belonged to Calliphoridae family. As a result, medical staff should be informed about this infestation and this parasite should be kept in mind especially in risky group of patients and necessary controls should be conducted.

RESUMO

Ophthalmomyiasis is the ocular infestation by dipterous larvae. It has been described in patients from rural areas, poor hygiene, or contact with animals. However, there are sporadic reports of this infestation in urban areas. We present the case of a young man without risk factors, from an urban area in southern Peru, in whom we found 10 larvae at ocular conjunctiva. The larvae were identified as Oestrus ovis, a fly that usually infests sheep and goats as part of their life cycle. We made a brief review of the case, highlighting the importance of adequately identifying the species that cause myiasis as well as its life cycle.
