Case Series of Phthirus pubis Infestation in Non-Perineal Regions.

Pediculosis has been reported in all countries and socio-economic classes. Due to the small size and translucent nature of their nits, patients with Pthirus pubis may be misdiagnosed. Here, we report three cases of Pthirus pubis infection involving different body sites, including the eyelashes, axillary region and head, respectively. This case series have discussed their clinical features and corresponding responses. A large number of eggs and adult pubic lice were observed under dermoscopic observation, which can be considered an effective tool for diagnosing Pthirus pubis and reducing the misdiagnosis rate.

Prevalence of Pediculus humunus capitis, Pediculus humanus corporis, and Pthirus pubis in Al-Kut, Iraq.

Lice infestations or pediculosis occurs throughout the world and is caused by Pediculus humunus capitis (head louse), Pediculus humanus corporis (body louse), and Pthirus pubis (crab louse). This study was conducted within March-October 2020 and aimed to investigate the presence of human lice among 1,632 individuals from 225 families living at different economic and social levels in AL-Kut city, Iraq, and its suburbs (urban, rural, and slum areas). Data collection was performed on volunteer families by completing survey forms and visual examinations. The families were divided by the number of members into 10-15, 7-9, 4-6, and 3-2 persons, for which, the infestation rates were estimated at 24.2%, 21.4%, 12.5%, and 8.6%, respectively. Moreover, in this study, urban, rural, and slum areas were infected at 11.5%, 33.6%, and 21.6 %, respectively. The infestation appeared in all ages, and the higher and lowest rates were obtained for the age ranges of 3-17 and 18-40 years old (79.04% and 20.9%), respectively. Based on the results, the rates of infestation were 21.8% and 13.3% in females and males, respectively. The findings of this study showed that the infection rate of Pediculus humanus corporis among the subjects aged 4-24 years old was 11.0% and that of Pthirus pubis was 3.0% in the cases aging 14-32 years old. Due to the high infestation with ectoparasites in these areas and large families, it is highly important to create conditions for health and provide information to control and prevent infection.

Eyelid Infestation: A Case Report of Atypical Phthiriasis Palpebrarum.

Phthiriasis palpebrarum is a rare parasitosis of the eyelashes caused by Phthirus pubis. This report describes an atypical case of this disease. A 72-year-old female patient suffered prolonged symptoms of severe left eye pruritus for 18 months, refractory to conventional eyelid hygienic measures, and anti-histaminic and corticosteroid medications. Slit-lamp examination showed multiple translucent oval structures adherent to the upper eyelashes, and 18 crab-like lice, which were mechanically removed and characterized as Phthirus pubis. Treatment was started with corticosteroid and antibiotic ointment, vaseline, and Blephademodex® wipes (Laboratoires Théa, Auvergne-Rhone-Alpes, France). After 2 weeks, all symptoms had subsided completely. Although rare, phthiriasis palpebrarum may be easily confused with frequent palpebral pathologies like blepharitis. A careful slit-lamp examination is central for proper evaluation and diagnosis. Mechanical removal of the lice is the most effective treatment but should be complemented by topical and/or systemic treatment. This report presented an atypical case of this disease.

First case of Phthirus pubis and Demodex co-infestation of the eyelids: a case report.

BACKGROUND: Phthirus pubis is an obligate parasite of human beings. Demodex spp. is a much more common parasite of human beings. However, P. pubis infestation accompanied by Demodex mite infestation in eye has not been reported. CASE PRESENTATION: We report the first case of Phthirus pubis and Demodex co-infestation on a 48-years-old woman. She presented to the hospital with itching and burning at her right eye for 2 weeks. Slit lamp examination revealed multiple nits and adults of P. pubis anchored to both upper and lower eyelashes. Eyelashes were trimmed, moxifloxacin eye ointment and fluorometholone eye drops were initiated daily. However, itching didn't improve after 2 weeks of treatment. Light microscopy examination of eyelashes revealed infestation with Demodex. The patient was treated with lid scrubs with 25% tea tree oil daily for 4 weeks and was completely cured. CONCLUSION: Our report shows the importance of an early and comprehensive diagnosis, because both phthiriasis palpebrarum and demodicosis can be confused with blepharitis.

Itching eyes after itching around the head.

Objective: To report the occurrence and management of an eyelashes infestation by Phthirus pubis. Methods: A 27-year-old female presented with itching in her right eye and head after she had been traveling in southern Italy five days earlier. Visual acuity (VA) was 20/20 in both eyes. Slit-lamp examination showed bilateral blepharitis. Moreover, mobile insects and eggs attached to the eyelashes were observed. A microbiological study was performed with a Phthirus pubis result. The patient was treated with mechanical dislodging. Results: The resolution of the infection was carried out removing every insect and egg. A vaseline application twice daily for 7 days was necessary to stifle any nits that could remain. Conclusions: The eyelashes pediculosis is frequently caused by Phthirus pubis. Only a minor percentage of the cases are due to Phthirus capitis, but the differential diagnosis is essential: there are Phthirus pubis pediculosis cases due to sexual abuse. A sexual history and screening for other sexually transmitted diseases is warranted.

Ectoparasites: Pediculosis and tungiasis.

Pediculosis is an infestation of lice on the body, head, or pubic region that occurs worldwide. Lice are ectoparasites of the order Phthiraptera that feed on the blood of infested hosts. Their morphotype dictates their clinical features. Body lice may transmit bacterial pathogens that cause trench fever, relapsing fever, and epidemic typhus, which are potentially life-threatening diseases that remain relevant in contemporary times. Recent data from some settings suggest that head lice may harbor pathogens. The epidemiology, clinical manifestations, and management of body, head, and pubic louse infestation are reviewed. New therapies for head lice and screening considerations for pubic lice are discussed. Tungiasis is an ectoparasitic disease caused by skin penetration by the female Tunga penetrans or, less commonly, Tunga trimamillata flea. It is endemic in Latin America, the Caribbean and sub-Saharan Africa and seen in travelers returning from these regions. Risk factors for acquiring tungiasis, associated morbidity, and potential strategies for prevention and treatment are discussed.

Phthirus pubis Infestation of the Scalp: A Case Report and Review of The Literature.

Phthirus pubis usually infests the pubis, groin, buttocks and perianal region. It can sometimes infest the thighs, abdomen, chest, axillae and beard. Eyelashes and eyebrows may be involved in children. The involvement of the scalp is very rare. We describe a case of P. pubis infestation located exclusively on the scalp in an adult woman. Neither lice/nits nor skin lesions were observed elsewhere, including eyebrows, eyelashes, axillae, pubis, buttocks and perianal region (the patient was hairless in the axillae and pubis). A review of the literature is enclosed.

Pubic lice infestation in man from Mhow, Madhya Pradesh.

Worldwide, 2-10% of human population is infested with pubic lice which are mostly found in the hair of pubic area, occasionally under the armpits, in the beard or mustache and on the eyebrows and eyelashes. They are usually transmitted through sexual contact or through toilet seats and bedding material. A twenty-year-old boy suffering from severe itching in the genital region during night hours submitted the lice for their identification in Department of Veterinary Parasitology, College of Veterinary Science and Animal Husbandry, Mhow. These lice were identified as Phthirus pubis.

Phthirus pubis Infestation of the Eyelids Presenting as Chronic Blepharoconjunctivitis in a 6-Year-Old Girl: A Case Report.

PURPOSE: To report the case of Phthirus pubis infestation of the eyelashes presenting as chronic blepharoconjunctivitis. CASE REPORT: A 6-year-old girl presented with a 2-month history of blepharoconjunctivitis unresponsive to topical antibiotics in the left eye. Slit-lamp examination revealed the presence of nits and adult parasites on the eyelashes. Parasitological examination confirmed adult forms and nits of Phthirus pubis. There was no evidence of infestation elsewhere. Outcome was favourable with mechanical removal and application of petroleum jelly. CONCLUSION: Careful slit-lamp examination of the eyelashes should be done in all patients presenting with ocular irritation symptoms.

Human head lice and pubic lice reveal the presence of several Acinetobacter species in Algiers, Algeria.

There are two majorspecies of medically important lice that parasitize humans: Phthirus pubis, found in pubic hair, and Pediculus humanus. Pediculus humanus consists of two eco types that live in specific niches on the human host: body lice (Pediculus humanus humanus), found on the human body and clothing, and head lice (Pediculus humanus capitis), found on the scalp. To date, only body lice are known to be vectors of human disease; however, it has recently been reported that the DNA of several bacterial agents has been detected in head lice, raising questions about their role in the transmission of pathogens. This issue caught our attention, in addition to the fact that the pathogenic bacteria associated with P. pubis and P. humanus capitis have never been investigated in Algeria. To investigate this,molecular techniques (real-time PCR) were used to screen for the presence of Acinetobacter spp., Bartonella spp., Borrelia spp. and Rickettsia prowazekii DNA from P. humanus capitis (64 lice) collected from schoolchildren,and P. pubis (4 lice),collected from one adultman living in Algiers. Positive samples for Acinetobacter spp.were identified by sequencing therpoBgene. Conventional PCR targeting the partial Cytb gene was used to determine the phylogenetic clade of the collected lice. Of the 64 samples collected, Acinetobacter spp. DNA was detected in 17/64 (27%) of head lice, identified as: A. baumannii (14%), A. johnsonii (11%) and A. variabilis (2%). Of the four P. pubissamples, 2(50%) were positive for A. johnsonii. The phylogenetic tree based on the Cytb gene revealed that P. humanus capitis were grouped into clades A and B. In this study, we report andidentify for the first time Acinetobacter spp.in Algerian P. pubis and P. humanus capitis. The detection of the genus Acinetobacter in lice should not be underestimated, especially in P. humanus capitis, which is distributed worldwide. However, additional epidemiological data are required to determine if human lice may act as an environmental reservoir and are actively involved in the propagation of these bacteria to humans.

Phthiriasis palpebrarum: diagnosis and treatment.

INTRODUCTION: Phthiriasis palpebrarum is an ectoparasitosis in which Phthirus pubis infest the eyelashes. It is rare and it can easily be misdiagnosed as blepharitis. The purpose of this study is to describe seven cases of phthiriasis palpebrarum so as to discuss its mode of infestation, diagnosis and treatment. PATIENTS AND METHODS: This is a study of all cases of phthiriasis palpebrarum reported in our laboratory. For each patient, an ophthalmic examination and parasitological examination of the eyelashes were performed. RESULTS: There were five men and two women. Their ages ranged from 4 to 50years with an average of 21.57years. There were four children and three adults. The main symptom was itching of the eyelids. Clinical signs included reddish-brown crusts at the base of the eyelashes in all the cases and visible lice and nits in three cases. Biomicroscopic examination showed lice and nits anchored to the eyelashes in three cases. In the other two cases, the initial diagnosis was felt to be blepharitis. In all cases, the diagnosis of phthiriasis palpebrarum was confirmed by parasitological examination of eyelashes, which revealed the presence of adult and nit forms of Phthirus pubis. The number of adult lice ranged from 1 to 30. In all cases, treatment was based on mechanical removal of both the lice and nits. Outcomes were favorable without recurrence. CONCLUSION: In conclusion, phthiriasis palpebrarum can be easily diagnosed by close examination of the eyelashes and eyelid margins at the slit lamp and can be managed mechanically. Parasitological examination of the eyelashes can confirm the diagnosis.

A Case of Phthiriasis Palpebrarum Treated with Tea Tree Oil in a Child

PURPOSE: The authors of the present study report a case of phthiriasis palpebrarum treated with petrolatum ointment and tea tree oil in a 12-month-old boy. CASE SUMMARY: A bluish-gray macule and blood clots were found on the central portion of the upper eyelid of a boy who had rubbed his eyelid vigorously 1 week prior. Several 0.5 mm sized brownish-gray nits and 1.6 mm sized lice on the eyelashes were visible and was diagnosed with phthiriasis palpebrarum after light microscopic examination. The nits and lice were gently removed mechanically with the help of a white petrolatum ointment (Vaseline) and the eyelashes were cleaned with 50% tea tree oil. Nits and lice were successfully eradicated without recurrence 10 days after daily treatment with petrolatum ointment and 10% tea tree oil eyelash cleansing.

A Case of Phthiriasis Occurring on the Scalp of a Child / 대한피부과학회지

Phthiriasis is a sexually transmitted disease by Phthirus pubis(pubic or crab louse) and usually affect the pubis in adult. Infestation of the eyelashes and scalp occurs rarely and mainly in children. In children, infestation may be transmitted by close contact with infected family, infected towel or other materials, or rarely by sexual abuse. So, careful examination is needed to find out familial source. We report a case of phthiriasis occuring on the scalp of a 16 month-old child whose mother has phthiriasis on the pubis and both axilla.

A Case of Phthiriasis Palpebrarum in Children

The majority of the crab louse is found in pubic hairs, but some of them will colonize axillary hairs, eyelashes, eyebrows and occasionally scalp hairs. In children crab louse may colonize the eyelashes and scalp hairs. The authors found a crab louse, Phthirus pubis and their nits on the eyelashes and scalp hiars of 25-months-old female who complained of foreign body and itching sensation of her right upper lid. Treatment is accomplished by careful mechanical removal of the louse and nits followed by the epilation and application of antibiotic eyedrops or ointments. We report a case of Phthiriasis palpebrarum in children.

A Case of Phthiriasis Palpebrarum

Phthiriasis has been usually known as a sexually-transmitted disease. The majority of these cases are found in the hair of the genital lesion, however, infestation of the eyelashed may occur. Eyeld involvement frequently causes blepharitis or conjunctivitis. The authors found a crab louse, Phthirus pubis and their nits on the eyelashes of 22-year-old female who complained foreign body and itching sensation of her right upper lid. Treatment is accomplished by careful mechanical removal of the louse and nits followed by the epilation and alllication of antibiotic eyedrops. We report a case of Phthiriasis palpebrarum with a review of the literatures.

Morpholgical Study of Korean Pubic Louse , Phthirus pubis ( Linnaeus , 1758 ) by Light and Scanning Electron Microscopy / 대한피부과학회지

By light and scanning electron microscopy, the morphologies of Korean pubic louse(Phthirus pubis) were described and measured. Especially, electron microscopic structures of palpus, tuft organ, sensilla basiconicum and palpal lobe were reviewed in detail. The variations were obserbed in the number of dorsal setae and the setae of membranous processes of abdomen. And also, the importance of public health and epidemiological aspects was discussed.
