CLINICAL CASE: A 46-year-old woman with no relevant medical history, native of Honduras and resident in Spain for one and a half months. The patient went to the Emergency Department due to inflammation of the upper eyelid of the right eye, with an area that simulated an abscess. This was drained (obtaining hardly any purulent content). Treatment was prescribed with oral and topical antibiotics, as well as an anti-inflammatory drug. One week later the patient returned, with improvement of the inflammatory signs, but with discomfort and corneal erosions. After eversion of the upper eyelid, a «worm¼ type parasite emerged from the tarsus. The extraction was completed with a clamp, and was later identified as Dermatobia hominis (Dh) by examination of a fresh specimen. The subsequent outcome of the patient was favourable. DISCUSSION: Preseptal cellulitis in patients from tropical and sub-tropical areas can be caused by Dh.

ABSTRACT This article presents a case of tick infestation of the lower eyelid by a previously unreported species. A 71-year-old male presented with a tick attached to the lower eyelid. The tick was identified morphologically, and then molecularly via polymerase chain reaction (PCR) and sequencing of its DNA. In addition, a review of the literature relevant to the genera of ticks associated with infestation of the human eye is provided. The tick, which was in the nymphal developmental stage, was first identified according to taxonomic keys as Dermacentor sp. For complete species identification, 16s rDNA gene PCR and sequencing were performed, which showed that the tick was D. marginatus. Systematizing tick species could assist physicians in determining the potential for transmission of tick-borne human diseases.
RESUMO Este artigo apresenta um caso de infestação por carrapatos da pálpebra inferior por uma espécie previamente não declarada. Um homem de 71 anos de idade apresentou-se com um carrapato grudado na pálpebra inferior. O carrapato foi identificado morfologicamente, e, em seguida, uma estrutura molecular através de reacção em cadeia da polimerase (PCR) e a sequenciação do seu DNA. Além disso, uma análise da literatura pertinente aos gêneros de carrapatos associados à infestação do olho humano é fornecido. O carrapato, que estava em fase de desenvolvimento das ninfas, foi identificado pela primeira vez de acordo com chaves taxonômicas com o Dermacentor sp. Para identificação de espécies completa, gene 16S rDNA PCR e sequenciamento foram realizadas, que mostrou que o carrapato foi D. marginatus. Sistematizando espécie de carrapato poderia ajudar os médicos a determinar o potencial de transmissão de doenças humanas transmitidas por carrapatos.

We describe a case of chronic conjunctivitis related to phthiriasis palpebrarum. A 36 year-old female presented with gradual pruritus and painless ocular hyperaemia over the previous 3 months. On examination, nasal pterygium, conjunctival hyperaemia, oedema, and mild hypertrophy of the palpebral margin were observed. A slit-lamp examination revealed numerous creamy oval structures approximately 1 mm in diameter localised in the middle area of the lashes, and bloody crusts and a semi-transparent deposit were present in the superior palpebral margin. Based on the observation of numerous nits at the base of the eyelashes and the ectoparasite in the palpebral margin, a diagnosis of phthiriasis palpebrarum was made. The patient was referred to an infectologist for evaluation of other sexually transmitted diseases and examination of other body areas. She was successfully treated with oral ivermectin, shampoo for ciliary hygiene and artificial tears. Other recommendations to avoid re-infestation were made, such as changing, washing and sterilising clothes, towels and sheets daily. This report emphasizes the importance of the correct diagnosis and management of this disease, considered as sexually transmitted.

A 74-year-old man from the rural area of Caicedonia, Valle del Cauca Province, was diagnosed with uncontrolled hypertension, stage IV chronic renal failure and severe anemia. Fifteen years earlier, while living in Guaviare Province, he was diagnosed with leishmaniasis-with lesions located on the right upper and lower eyelids, left auricle and limbs. At that time, he received an incomplete treatment with antimonials. The patient had experienced 8 years of progressive mucosal lesions located in the upper lip, nasal mucosa and right upper and lower eyelids (figure 1). A histopathological diagnosis of leishmaniasis was made and confirmed by polymerase chain reaction (figure 2). Treatment with antimonials (Glucantime) was contraindicated due to the patient's comorbidities. Inpatient supervised treatment with miltefosine (Impavido 50 mg capsules) was initiated according to the national guidelines of 1.8 mg/kg/day for 28 days. Clinical follow up and routine laboratory tests (creatinine, BUN, liver function tests and complete blood counts) were done during and after treatment; no complications were reported. Medical follow up was continued until the Internal medicine, ophthalmology, and plastic surgery consultations were provided for subsequent management of the pathology. Mucocutaneous leishmaniasis is a serious preventable complication of cutaneous leishmaniasis. This case illustrated a failure in opportune diagnosis and treatment of this disease as a consequence of an inadequate leishmaniasis control program. The case indicated the effectiveness of miltefosine as a therapeutic option in patients for whom antimonial treatment is contraindicated.

A 50 year-old man, a United States resident, presented in Texas with a violaceous non-ulcerating lesion, involving the entire lower eyelid. The patient had traveled to a jungle area of Belize several hours drive from the capital city. Leishmania mexicana was isolated. The lesion only partially resolved after an initial course of sodium stibogluconate, requiring retreatment. At two years of follow-up, there was no relapse. The parasite isolated from the patient caused a progressive, non-ulcerating lesion in an experimental mouse footpad infection. This is an unusual case of cutaneous leishmaniasis in a traveler. Travelers must be educated about personal protective measures to prevent exotic infections acquired during travel.

Os autores descrevem um caso de paciente de 16 anos portadora de fitiríase palpebral tratada com ivermectina por via oral. Embora esta droga já esteja em uso há vários anos para terapêutica de outras parasitoses, ela também é reconhecidamente eficaz contra o Phthirus pubis. A maior vantagem de seu emprego na enfermidade aqui descrita pode residir na comodidade posológica.
