Norwegian scabies in human immunodeficiency virus and tuberculosis-infected child: A case report.

Norwegian scabies is a rare scabies with the manifestation of thick crusts of the extremities of the skin that contain eggs and mites. Several conditions in which scabies infection is easily transmitted include immunocompromised, home nursing, and severe neurological disorder. The aim of this case report was to present a thorough analysis of a comprehensive resource for the management of Norwegian scabies patients, with a specific focus on individuals who also have HIV or other immunocompromising diseases. A 1-year-and-7-month-old boy was presented to the hospital with a chief complaint of a thick crust that he had experienced for four months. It began as a red papule in the lower extremity, then crusted and spread to the whole body. The patient kept scratching due to itching, had a recurrent fever and diarrhea for three months, and cough for one month. The patient was diagnosed with human immunodeficiency virus (HIV) and pulmonary tuberculosis at three months, suspected to get the infection from the parents. Sarcoptes scabiei was found from microscopy examination of skin scraping. The patient received holistic treatment, including antiretroviral drugs, antituberculosis medication, scabies treatment, and malnutrition treatment. Appropriate scabies treatment aimed at peeling crusted skin, relieving itching, and increasing the patient ability to use the extremities. Comorbidity conditions caused by HIV and pulmonary tuberculosis should also be treated to optimize the outcome. The patient was discharged in good condition with sanitation education and regular follow-up at the outpatient clinic. This case highlights that Sarcoptes scabiei infestation may be a clue to an immunocompromised condition. Holistic therapy aiming to cure underlying infection, infestation and underlying nutrition and psychosocial problems must be addressed to fully cure this high-burden case.

The hidden scabies: a rare case of atypical Norwegian scabies, case report and literature review.

BACKGROUND: Norwegian scabies is a rare dermatological manifestation that usually affects the most fragile populations, such as elderly and immunocompromised patients, and its diagnosis is quite complex, due to its low prevalence in the general population and because of a broad spectrum manifestation. CASE PRESENTATION: Here we describe a rare case of Norwegian scabies that was previously misdiagnosed in a sixteen year old patient affected by Down syndrome and we conducted a non-systematic literature review about this topic. Lesions were atypical, pruritic and associated with periodic desquamation of the palms and soles and after a series of specialist evaluations, she finally underwent topical treatment with complete remission. CONCLUSION: It is therefore crucial to take in consideration the relation between Down syndrome and community acquired crusted scabies, to enable preventative measures, early detection, and proper treatment.

Evaluation and Management of Pruritus and Scabies in the Elderly Population.

Pruritus is the most common dermatologic complaint in the geriatric population. Its growing prevalence coincides with the rapid growth of the elderly population (>65 years of age) in the United States. According to the US Census Bureau, 16.9% of the population, or more than 56 million adults 65 years and older, lived in the United States in 2022. Pruritus is a condition that accompanies a diverse array of underlying etiologic factors. The mechanism of normal itch impulse transmission has been recently elucidated. The itch sensation originates from epidermal/dermal receptors connected to unmyelinated, afferent C-fibers that transmit the impulse from the periphery.

Crusted Scabies Presenting as Erythroderma in a Patient With Iatrogenic Immunosuppression for Treatment of Granulomatosis With Polyangiitis.

The diagnosis of scabies can be difficult when the infection presents as erythroderma. Crusted scabies is a severe form of scabies caused by cutaneous ectoparasitic infection by the mite Sarcoptes scabiei var hominis. Crusted scabies most commonly occurs in patients with underlying immunosuppression from acquired infection or subsequent to solid organ or bone marrow transplantation. We present a rare case of a patient with granulomatosis with polyangiitis (GPA) who developed azathioprine-induced myelosuppression and subsequent erythrodermic crusted scabies. It is critical to maintain a broad differential when patients present with erythroderma, especially in the setting of medication-induced immunosuppression for the treatment of autoimmune disease.

Case of concurrence of bullous pemphigoid and Norwegian scabies.

Bullous pemphigoid (BP) with scabies is a condition rarely encountered in clinical practice, and when it is encountered, it is often due to the use of immunosuppressants. This paper is a report on a patient with BP and scabies, who developed scabs after taking dexamethasone. It should be noted that BP antibody is necessary, which can distinguish BP with scabies and bullous scabies, and the treatment options for the two diseases are different.

[Post-scabies itch: an overview of causes and treatment strategies]. / Postscabiësjeuk.

The main manifestation of scabies infection is intense itching. This itch is experienced by nearly every individual affected by the infestation and may persist even after successful treatment of scabies. In certain cases, this post-scabies itch can persist for several weeks to months. In rare cases, it can even progress into a delusional parasitosis related to scabies. This article highlights three cases and explores the underlying causes of itch as well as treatment strategies.

Bullous Pemphigoid and Scabies: Is There an Association?

BACKGROUND: Bullous Pemphigoid (BP) is an autoimmune subepithelial bullous disease. Several reports suggested an association between BP and scabies. OBJECTIVE: We aimed to evaluate whether an association between BP and scabies exists. METHODS: This is a retrospective matched case-control study. We retrospectively identified BP patients treated in our clinic between January 1, 2009, and December 31, 2016. Each patient was assigned to 3 control subjects (matched by age and sex) treated in our clinic, not due to BP. The study group was examined for a scabies diagnosis within the 3 years prior to BP diagnosis; the control group was examined for a scabies diagnosis 3 years prior to its first visit in our clinic. RESULTS: Fifteen out of the 87 (17.2%) BP patients were diagnosed with scabies within the 3 years prior to their initial BP diagnosis, compared to only 4.2% (11 out of 261) among the control group. The odds ratio of scabies history was 4 times higher among BP patients compared to the control group (OR=4.23; 95% CI: 1.50–11.91, P=0.007). LIMITATIONS: A retrospective study design. CONCLUSIONS: An association between scabies diagnosis and BP is demonstrated in our study. J Drugs Dermatol. 2022;21(9):1009-1011. doi:10.36849/JDD.4900.
