Approximately half of all patients presenting to dermatologists exhibit signs and symptoms of psychiatric conditions that are either primary or secondary to cutaneous disease. Because patients typically resist psychiatric consult, dermatologists often are on the front line in evaluating and treating these patients. Accordingly, distinguishing the specific underlying or resulting psychiatric condition is essential for effective treatment. The etiology, epidemiology, clinical presentation, diagnosis, and first-line treatment of specific primary psychiatric causes of dermatologic conditions, including delusional infestation, Morgellons syndrome, olfactory reference syndrome, body dysmorphic disorder, excoriation disorder, trichotillomania, and dermatitis artefacta are discussed here, followed by a discussion of the recommended treatment approach with an overview of the different first-line therapies discussed in this review, specifically cognitive behavioral therapy, atypical antipsychotics, selective serotonin reuptake inhibitors, and tricyclic antidepressants...

BACKGROUND: Immunization with killed Leishmania promastigotes without adjuvant was considered as safe, but gave variable rates of protection. Taking advantage of the immuno-modulatory effect of caffeic acid (CA), a natural polyphenolic antioxidant, we investigated its potentiating effect in autoclaved Leishmania major (ALM)-induced protection of Leishmania major-infected BALB/c. METHODS: First, BALB/c mice were sensitized for 6 weeks either with CA, or ALM alone or combined with caffeic acid (ALM-CA) or Freund's adjuvant (ALM-FA), and subsequently infected with L...

BACKGROUND: Atopic dermatitis (AD) is characterized by skin barrier defects, Th2 activation, and increased risk for cutaneous and extracutaneous infections. In clinical trials, dupilumab appeared to decrease rates of skin infections in AD. OBJECTIVE: We aimed to determine the impact of dupilumab on rates of skin and other infections in patients with moderate-to-severe AD. METHODS: We conducted a systematic review and meta-analysis of randomized controlled trials (RCTs) of dupilumab for AD...

BACKGOUND: Over the last thirty years, the scientific community has become increasingly interested in the intestinal flora, whether commensal or pathogenic, and its impact on other organs. In dermatology, the correlation between intestinal microbial agents and cutaneous lesions is well established. Giardia duodenalis, an intestinal parasite, has been particularly widely studied. The aim of this work is to provide a review of studies demonstrating the involvement of G. duodenalis in various forms of dermatosis...

BACKGROUND: Delusional parasitosis (DP) is an uncommon psychiatric disorder. Patients suffering from this disorder have the fixed false belief of being infested by a parasite. Because of this condition, patients mainly consult with dermatologists or general practitioners. They are often reluctant to see a psychiatrist and to take treatment with antipsychotics because of their belief. The following describes the case of a woman who has the particularity that the DP started a few days after sertraline interruption...

Significant new insights are being made into tick modulation of host immune defenses and the implications of those host defense changes on tick-borne pathogen transmission and establishment of infection. Understanding tick saliva complexity increased with construction and analyses of salivary gland cDNA libraries. High throughput next generation sequencing and advances in proteomics are revealing greater complexity of saliva, nature of gene families and differential gene expression patterns not previously attainable...

Hookworm-related cutaneous larva migrans (HRCLM) is caused by the penetration and migration in the epidermis of larvae of Ancylostoma braziliense and Ancylostoma caninum. It is characterized by slightly raised and erythematous tracks, located especially on the feet. These tracks may be single or multiple, serpiginous or linear, ramified and intertwined, accompanied by pruritus. Atypical clinical presentations of HRCLM are currently more frequent than in the past. We present six patients with bullous HRCLM and discuss the possible pathogenetic factors...

BACKGROUND: Myiasis designates the infestation of live human and vertebrate animals with dipterous (two-winged) larvae (maggots) and is the fourth most common travel-associated skin disease. Furuncle is the most common aspect of cutaneous myiasis. CASE PRESENTATION: A 24-year-old Caucasian female had been back from Cap-Vert. She described pruritus, slight pain, and the sensation of a foreign body moving in the eyelid. Physical examination showed a single furuncle-like nodule with surrounding erythema and a central pore of the upper eyelid through which a serosanguinous fluid was exuding...

Scabies, a parasitic infestation caused by the mite Sarcoptes scabiei, is diagnosed by observing either the mite, its ova, or its excrement. The mite tracts, known as burrows and a characteristic presentation of the pruritic condition, are typically found on the web spaces between the fingers. Other cutaneous lesions include excoriated papules, pustules, and vesicles. However, atypical clinical variants of scabies, such as bullous, crusted, hidden, incognito, nodular, and scalp forms of the parasitic infestation, mimic the morphologic features of other non-parasitic dermatoses...

Companion animals are an important aspect in human life. However, they may also be considered a source of pathogens. An example of zoonotic parasitoses is toxocarosis or cutaneous larva migrans (CLM). The aim of the study was to detect zoonotic nematodes of dogs living in different areas and the intensity of contamination in parasite polluted environments that are hazardous to human health. The fecal samples were examined using standard flotation and decantation methods as well as McMaster's quantitative technique...

The clinical manifestations of scabies infestation vary according to age, making the diagnosis challenging, particularly for primary care providers and dermatologists who do not routinely care for young children. We present seven cases of newborns and infants who developed inflammatory burrows and nodules early in the course, which is not typical of the eruption seen in older children and adults. We review the cutaneous features, differential diagnosis, and treatment recommendations for scabies in different age groups...

Scabies is a parasitic disease due to infestation of skin by the burrowing mite Sarcoptes scabiei. Scabies is a major public health problem and endemic in resource poor communities worldwide affecting over 100 million people. Associated bacterial infections cause substantial morbidity, and in severe cases can lead to renal and cardiac diseases. Mite infestation of the skin causes localised cutaneous inflammation, pruritus, skin lesions, and allergic and inflammatory responses are mounted by the host against the mite and its products...

Myiasis, infestation of live human and vertebrate animals by larvae, can complicate ulcers and open wounds. Although myiasis occurs in neglected erosions of pemphigus, such a complication is not documented in the literature. Herein, we report a case of myiasis complicating pemphigus vulgaris and describe its dermatoscopic features.

BACKGROUND: The prevalence of skin disease in low and middle income countries is high and communicable skin diseases are a significant public health problem. Tungiasis is an ectoparasite infestation caused by the flea Tunga penetrans, which has a widespread geographical distribution. Tungiasis causes painful skin lesions and may affect activities of daily living. OBJECTIVE: We wished to determine the prevalence and impact of tungiasis and scabies in schoolchildren in southern Ethiopia...

Neotrombicula autumnalis is an arthropod living in the soil and parasitizes animals only in its larval stage. Depending on climatic conditions, one to five life cycles can take place in a single year. Human infestation is probably underestimated and can be easily missed due to non-pathognomonic cutaneous manifestations in absence of systemic signs. We describe a case of human trombiculiasis and discuss the diagnostic and therapeutic management of this ‘synanthropic’ dermatosis.

BACKGROUND: Fluralaner and afoxolaner are isoxazolines licensed for the treatment of flea and tick infestations. Isoxazolines have also shown efficacy for treatment of demodicosis. Nothing is known about the impact of these compounds on the populations of Demodex in healthy dogs. HYPOTHESIS/OBJECTIVES: The objective of this study was to measure the prevalence of Demodex in the skin of healthy dogs prior to and following the use of either afoxolaner or fluralaner, using real-time PCR (RT-PCR) for Demodex DNA...

Myiasis is an infestation of tissues and organs of humans and animals by Diptera larvae (flies, horseflies, mosquitoes). They are located at different body sites, and classified clinically as cutaneous, visceral and cavitary. We report a 26-year-old woman with a history of seborrheic dermatitis and recent trip to Brazil. She presented with a seven days history of suppurating wounds in the parieto-occipital area of the scalp. At physical examination we found three ulcers of approximately 1.5 cm each, with multiple mobile larvae inside...

Rareş G M Căpitan, Chiara Noli
BACKGROUND: Pelodera strongyloides infestation has rarely been reported in dogs. It is a saprophytic free-living nematode, found in moist decaying organic matter, whose L3 larval stages occasionally can invade the skin of dogs and humans. Larvae penetrate the follicular infundibula causing an erythematous and pruritic dermatitis. The disease is usually diagnosed by deep skin scraping or histopathology, with large numbers of parasites readily identified in hair follicles. CASE REPORT: Pelodera strongyloides dermatitis was diagnosed in a six-year-old mixed breed dog presenting with alopecia, erythema and severe pruritus on the ventrum and limbs...
