BACKGROUND: Canine screw-worm myiasis due to Cochliomyia hominivorax or Chrysomya bezziana has traditionally been treated with extra-label use of ivermectin. The larvicidal activities of nitenpyram and spinosad/milbemycin also have been described, but there have been no reports to describe the efficacy of isoxazolines such as afoxolaner. OBJECTIVES: To evaluate and compare the efficacy of spinosad, spinosad/milbemycin, milbemycin, nitenpyram and afoxolaner for the treatment of canine screw-worm myiasis...

Ascomycetes and zygomycetes account for the majority of (i) fungi responsible for cutaneous, subcutaneous, and invasive human fungal infections, (ii) plant fungal pathogens, (iii) fungi that threaten global biodiversity, (iv) fungal agents of agricultural spoilage, and (v) fungi in water-damaged buildings. Rapid recognition of fungal infection (or contamination) enables early treatment (or remediation). A bioinformatics search found homologues of Saccharomyces cerevisiae Mnn9p present in members of the Zygomycota and Ascomycota phyla and absent in members of the Chytridiomycota and Basidiomycota...

Delusional infestations are psychodermatologic disorders in which those affected have a false belief they are infested by parasites and/or "growing" inanimate objects from cutaneous surfaces. Individuals with delusional parasitosis (DP) believe parasites, bacteria, worms, mites, or other living organisms are the source of cutaneous symptoms, while those with Morgellons disease (MD) attribute their symptoms to growth of small fibers or inorganic material. In both DP and MD, self-inflicted, non-healing cutaneous lesions caused by scratching at the affected areas to alleviate symptoms are commonly observed...

Tick infestation is rarely seen in ophthalmological practice. We report the case of a 73-year-old woman who presented with edema and erythema of her right upper eyelid. Biomicroscopic examination revealed a tick firmly attached to the eyelid margin. The tick was successfully removed using fine tweezers, and within a few days, the patient had fully recovered without sequelae. Ticks are a threat to public health as they are known vectors of numerous infectious agents responsible for serious pathologies such as Lyme disease...

Scabies, a mite infestation caused by 'Sarcoptes scabiei', most commonly presents as pruritic linear burrows where the mite has invaded the skin. Scabies variant such as bullous, crusted, hidden, incognito, nodular and scalp-mimic the other conditions. In addition, atypical presentations of scabies can masquerade as dermatitis herpetiformis, ecchymosis, Langerhans cell histiocytosis, systemic lupus erythematosus, urticaria, and urticaria pigmentosa. A 59-year-old male presented with non-pruritic papulosquamous plaques on his chest, abdomen, and back resembling lesions of pityriasis rosea in morphology and distribution...

A large proportion of patients seen in dermatology practices have underlying psychological issues associated with their skin diseases. One of the most flagrant examples of this are patients with delusions of parasitosis. These patients have false fixed beliefs that they are infested by parasites and experience cutaneous sensations of crawling, biting, and stinging associated with their delusions. There is no organic skin disorder and all cutaneous manifestations are self-induced. Rather than a psychiatrist, the dermatologist is often designated by the patient to handle the chief complaint, even though the main disorder is psychogenic...

Soil and freshwater-dwelling amoebae may opportunistically infect the skin and evoke a granulomatous dermatitis that camouflages their underlying morphology. Amoebic infestations are incredibly rare in the U.S., predominantly occurring in the young, elderly, and immunocompromised. Sadly, because diagnosis is difficult and unsuspected, most cases are diagnosed at autopsy. The following case is of a healthy 84-year-old man with a non-healing nodulo-ulcerative cutaneous lesion on his left forearm that appeared following a gardening injury...

Morgellons disease (MD) is a skin condition characterized by the presence of multicolored filaments that lie under, are embedded in, or project from skin. Although the condition may have a longer history, disease matching the above description was first reported in the US in 2002. Since that time, the condition that we know as MD has become a polemic topic. Because individuals afflicted with the disease may have crawling or stinging sensations and sometimes believe they have an insect or parasite infestation, most medical practitioners consider MD a purely delusional disorder...

Subacute cutaneous lupus erythematosus is a clinically distinct form of cutaneous lupus erythematosus, with age of onset typically in the second to fifth decades. Eleven cases have been reported in childhood, and we present the first known case of subacute cutaneous lupus erythematosus in identical twins. Although flares are typically photo-induced, we present an annular eruption typical of subacute cutaneous lupus erythematosus with concurrent pinworm infestation, with recurrence of disease with cutaneous larva migrans...

Skin wound healing has been widely studied in mammalian models but the information on teleost cutaneous healing is sparse and frequently considered in the context of viral or bacterial infections or parasitic infestations in aquaculture. In the present study a detailed time course (0 h, 6 h, 1, 2, 3 and 4 days) coupled to morphology and gene expression analysis revealed rapid regeneration of skin without scarring in a marine teleost after a superficial wound caused by the loss of a large area of scales...

Understanding the effects of age on the epidemiology of diseases primarily affecting the skin is important to the practice of dermatology, both for proper allocation of resources and for optimal patient-centered care. To fully appreciate the effect that age may have on the population-based calculations of incidence of diseases primarily affecting the skin in Olmsted County, Minnesota, and worldwide, we performed a review of all relevant Rochester Epidemiology Project-published data and compared them to similar reports in the worldwide English literature...

Climate change contributes to the increase in severity and frequency of flooding, which is the most frequent and deadly disaster worldwide. Flood-related damage can be very severe and include health effects. Among those health impacts, dermatological diseases are one of the most frequently encountered. Both infectious and noninfectious dermatological conditions are increasing after flooding. We searched PubMed using the search term climate change OR global warming OR rainfall OR flooding OR skin.

Cutaneous infections and infestations are common among children and adolescents. Ectoparasitic infestations affect individuals across the globe. Head lice, body lice, scabies, and infestations with bed bugs are seen in individuals who reside in both resource poor areas and in developed countries. Superficial cutaneous and mucosal candida infections occur throughout the life cycle. Dermatophyte infections of keratin-containing skin and skin structures result in tinea capitis (scalp), tinea corporis (body), tinea pedis (foot), and tinea unguium (nails)...

Tick-borne diseases (TBDs) are emerging and reemerging diseases transmitted by ticks, which portray wide heterogeneity and global distribution. TBDs may present acute clinical pictures that resemble those of autoimmune diseases (i.e., musculoskeletal symptoms, cutaneous involvement, neurologic impairment, renal failure, etc.), and in some cases infection is considered a triggering factor for autoimmunity (e.g., rheumatoid arthritis, autoimmune thyroid disease, vasculitides). The clinician should consider TBDs among the differential diagnoses when approaching autoimmune-like signs in areas of tick infestation...

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...
