Haemodialysis is the most frequent form of renal replacement therapy (RRT) in patients with end-stage renal disorder (ESRD). Patients with ESRD frequently develop skin problems, mainly xerosis, pruritus and hyperpigmentation, as well as bullous diseases, mainly porphyria or pseudoporphyria and, in some cases, bullous pemphigoid (BP). BP is the most common autoimmune sub-epidermal blistering disease, and it predominantly affects elderly people. Clinically, BP is characterised by generalised pruritic, bullous eruptions and urticaria-like lesions...

OBJECTIVE: Xerosis is a serious problem among the very old. It is a dermatological challenge caused by significant alterations in stratum corneum (SC) function and structure. Two negative changes in aged skin are: (i) the enhanced skin surface pH and (ii) the altered SC lipid content, composition and ordering. METHODS: Therefore, we investigated the way in which an acidic skin care product with different plant oils affects SC function, structure and lipid profile in older subjects with dry skin...

BACKGROUND: "Holi" is a spring festival celebrated primarily in the Indian subcontinent and also abroad by expatriate Indians. It is a festival of colors, traditionally celebrated by mutual application of colors in different forms on a particular day of the year. These colors frequently comprise a range of synthetic dyes which have harmful effects on the skin and mucosae. Children take part in this colorful festival with much enthusiasm and vigor, making them prone to develop different "Holi"-related dermatoses...

Phototherapy is a valuable therapeutic tool in Dermatology, but there may be drawbacks. Acute and long-term adverse effects, of variable severity, include skin erythema, xerosis, pruritus, blistering, altered pigmentation, photoaging, and photocarcinogenesis. Despite concerns over the carcinogenic potential of ultraviolet radiation, most studies have not found an increased risk of non-melanoma or melanoma skin cancer in patients treated with ultraviolet B (broadband and narrowband) and ultraviolet A1 phototherapy...

BACKGROUND: Although a number of pathological processes resulting in amyloid deposition has been described in lichen amyloidosus (LA), no attention has been given to the involvement of sweat glands/ducts in the pathogenesis of LA. According to recent studies, the follicular structures are usually spared in serial histologic sections of LA and deposits of amyloid are likely to be confined to areas that display xerosis, suggesting that decreases in skin wetness by sweating disturbance seem to initiate LA...

This chapter summarizes recent advances in the pathogenesis and management of Sjögren's syndrome (SS). Major topics are newly described pathomechanisms and cutaneous manifestations of SS, with special references to hypohidrosis and related mucocutaneous manifestations. Although the significance of cutaneous manifestations in SS has been gradually recognized in rheumatologists, sudomotor function has not been fully evaluated and recognized in the diagnosis of SS except by dermatologists. SS is a relatively underestimated collagen disease in contrast to systemic lupus erythematosus, systemic sclerosis, or dermatomyositis, and special care is needed not to misdiagnose SS when we see patients with common skin diseases such as drug eruption, infectious skin disease, or xerosis in daily practice...

Many factors such as food or environmental allergens, bacteria, fungi, and mental stress aggravate the condition of atopic dermatitis (AD) eczema. Sweating can also exacerbate AD, and patients are aware of that. In the past, it has been reported that contamination of skin surface antigens by sweat induces acute allergic reactions and that sweating functions of AD patients via axonal reflexes are decreased. Histamine demonstrably inhibits acetylcholine-induced sweating in both mice and humans via histamine H1 receptor-mediated signaling...

Itch is a common symptom in the elderly population over 65 years old, and is often a chronic condition lasting more than 6 weeks. As in all age groups, but especially in the elderly, there can be a significant effect on the general health status and quality of life, with impaired daily activities and lack of sleep, which can also lead in some cases to depression or anxiety. The cause of chronic itch in the elderly is often multifactorial due to physiological changes in the aging skin, including impaired skin barrier function, and also due to decline in immunological (immunosenescence), neurological, and psychological changes associated with age...

BACKGROUND: The purpose of our study is to find out in which weeks and in which cumulative doses the side effects emerge and to study whether or not there is a significant variance between the observed period and doses of the emergent side effects of the patients taking the daily doses of below and above 0.5 mg/kg. METHODS: Patients were started treatment with doses of 0.25-1 mg/kg isotretinoin, and a form was given to the patients to mark which probable side effects occurred in which weeks and called for weekly follow-up for the first 2 months...

OBJECTIVE: Diagnoses of skin, mucosae, hair and nail manifestations in malignant diseases are often challenging because of life-threatening drug reactions, opportunistic infections or skin involvement of primary processes. Description of morphology, configuration and distribution of lesions is important in order to differentiate the self-healing eruptions from serious side effects of chemotherapy. There are case reports from Turkey including dermatological manifestations of malignancies and case series in adult patients but there are no published large group studies assessing all manifestations in children...

BACKGROUND: Xeroderma pigmentosum (XP) is an autosomal recessive disorder characterized by xerosis, ultraviolet light sensitivity, and cutaneous dyspigmentation. Due to defects in their DNA repair mechanism, genetic mutations and carcinogenesis inevitably occurs in almost all patients. In these patients, reconstruction of cutaneous malignancies in the head and neck area is associated with some challenges such as likelihood of recurrence and an aggressive clinical course. The aim of this study is to discuss the therapeutic options and challenges commonly seen during the course of treatment...

BACKGROUND: Corynebacterium xerosis is a commensal organism found in skin and mucous membranes of humans. It is considered an unusual pathogen, and it is rarely found in human and animal clinical samples. Here we describe the isolation of C. xerosis from a 4-months-old Pelifolk lamb located in Tesistán, central western Mexico. This microorganism should be considered for differential diagnosis in cutaneous abscessed lesions in sheep, as it represents a zoonotic risk factor for human infection in sheep farms...

The ichthyoses, also known as disorders of keratinization (DOK), encompass a heterogeneous group of skin diseases linked by the common finding of abnormal barrier function, which initiates a default compensatory pathway of hyperproliferation, resulting in the characteristic clinical manifestation of localized and/or generalized scaling. Additional cutaneous findings frequently seen in ichthyoses include generalized xerosis, erythroderma, palmoplantar keratoderma, hypohydrosis, and recurrent infections. In 2009, the Ichthyosis Consensus Conference established a classification consensus for DOK based on pathophysiology, clinical manifestations, and mode of inheritance...
