Ivermectin (IVM) is a broad-spectrum anti-parasitic drug with significant anti-inflammatory properties. The emergence of treatment resistance to lindane, permethrin, and possibly malathion complicates the global strategy for management of common parasitic skin diseases such as scabies and head lice. In this regard. IVM has been safely and effectively used in the treatment of these common human infestations. In addition, IVM may be useful in inflammatory cutaneous disorders such as papulopustular rosacea where demodex may play a role in pathogenesis...

Cutaneous myiasis is the infestation of the skin or mucous membranes by larvae of the order Diptera. Wound myiasis affect the skin with a previous lesion, and it may consume both dead and living tissue. Finger infestation is rarely a cause of death, but it may provoke considerable morbidity. Prompt wound exploration and careful total larvae removal is essential to achieve healing. In the reported case, the patient was presented in an advanced stage of the infestation, with a large area of finger necrosis and amputation, associated with cellulitis extending from the finger's base to the hand...

Some cutaneous inflammatory disorders are typified by a predominant or exclusive localization in the dermis. They can be further subdivided by the principal cell types into lymphocytic, neutrophilic, and eosinophilic infiltrates, and mixtures of them are also seen in a proportion of cases. This review considers such conditions. Included among the lymphoid lesions are viral exanthems, pigmented purpuras, gyrate erythemas, polymorphous light eruption, lupus tumidus, and cutaneous lymphoid hyperplasia. Neutrophilic infiltrates are represented by infections, Sweet syndrome, pyoderma gangrenosum, and hidradenitis suppurativa, as well as a group of so-called "autoinflammatory" dermatitides comprising polymorphonuclear leukocytes...

Phenol (carbolic acid) is one of the oldest antiseptic agents. Apart from being used in many commercially available products, in rural India, it is often used in the household to prevent snake infestation. We hereby present four cases of acute carbolic acid poisoning which we saw over the last monsoon. The cases highlight the multiple routes of absorption of carbolic acid as well as its multi-organ complications which often necessitate intensive care of local therapy decreases systemic phenol absorption from cutaneous exposure and may help in reducing severity...

BACKGROUND: Acaricides are used to treat and prevent tick infestations, and a common clinical scenario is to administer an acaricide on observing an attached tick. Consequently, immediate acaricidal efficacy (onset of activity and speed of kill) results are clinically valuable. This study evaluated the immediate efficacy of four commercially available acaricides against adult Rhipicephalus sanguineus (sensu lato). METHODS: Forty dogs were blocked on hair length and tick carrying capacity, then randomly assigned to receive one of four treatments (fluralaner, sarolaner, imidacloprid + permethrin, or afoxolaner) or left untreated as controls...

Ekbom syndrome or delusional parasitosis is a rare disease characterized by the unwavering conviction of having cutaneous infestation of insects or parasites. This is a monothematic delusion of hallucinatory origin that typically affects older women. We report the case of three patients with delusional parasitosis in different clinical settings. The first patient suffered from isolated delusional parasitosis corresponding to the condition described by Karl Ekbom. The second case suffered from secondary delusional parasitosis, occurring in the setting of leukoencephalopathy (CADASIL)...

Mio Nakamura, John Koo
In monosymptomatic hypochondriacal psychosis (MHP), such as delusional infestation (DI), the patient has a fixed, false, encapsulated belief associated with tactile hallucinations (TH), most commonly formication, which is defined as cutaneous sensations of crawling, stinging, biting, etc., without evidence of infestation. Drug-induced TH should be considered in patients with suspected MHP. Although recreational drugs such as cocaine, amphetamines, and narcotics are well known to induce TH, many busy practicing dermatologists may not be familiar with other types of medications that can induce TH...

Strongyloidiasis is a parasitic infestation caused by Strongyloides stercoralis. Most cases are asymptomatic; however, symptomatic patients may present with a wide range of non-specific cutaneous, pulmonary, or gastrointestinal symptoms posing a diagnostic dilemma and delay in diagnosis. We report a case of a 58-year-old female who presented with months of generalized pruritus and abdominal discomfort along with persistent eosinophilia due to strongyloidiasis, which completely resolved with treatment.

Eight Bald Eagle ( Haliaeetus leucocephalus ) nestlings heavily infested with larval ticks were found in or under a nest near the confluence of the Verde and Salt rivers in Arizona in 2009-11. The 8-12-wk-old nestlings were slow to respond to stimuli and exhibited generalized muscle weakness or paresis of the pelvic limbs. Numerous cutaneous and subcutaneous hemorrhages were associated with sites of tick attachment. Ticks were identified as Argas radiatus and Argas ricei. Treatment with acaricides and infection with West Nile virus (WNV) may have confounded the clinical presentation in 2009 and 2010...

Myiasis is defined as the infestation of live vertebrates, either humans or animals, with dipterous larvae. Many organs can be infested by these larvae with cutaneous myiasis being the most common form. Cutaneous myiasis can be divided into three categories: localized furuncular myiasis, migratory myiaisis and wound myiasis, which occurs when fly larvae infest the open wounds of the host. Human myiasis has worldwide distribution, with more species and a heavier burden in tropical and subtropical countries. In recent years with increased travel to the tropics, myiasis has become common in returning travelers from these regions, Furuncular myiasis, mainly Dermatobia homonis becomes the most common form seen among them...

Dirofilaria repens is a filarial nematode which cause subcutaneous dirofilariosis. Dogs, foxes and cats are the definitive hosts and principal reservoirs of the parasite. We report cases of D. repens infestation in non-descript canines from Goa, India. The nematodes were enclosed within fibrous capsule or freely present in the tunica vaginalis of the testes, in sub-cutaneous tissue of foreleg and body cavity. The parasite showed well-developed thick multilayered cuticular ridges in the outermost layer, followed by transverse smooth muscles striations...

The popularity of international travel continues to increase among Americans, even though they often experience subsequent illness on return from their journey. The pathogens responsible are not necessarily endemic to the destination itself but are often the result of poor sanitary conditions or activities engaged in while away. Skin disease ranks third among all medical concerns in returning travelers. This review addresses the pathogenesis, epidemiology, clinical presentation, and treatment of the most common skin diseases in returning travelers: insect bites and bedbugs, cutaneous larva migrans, scabies, tungiasis, myiasis, leishmaniasis, viral exanthems, and marine envenomation...
