Active clinical trials for "Pruritus"

Vulvar contact dermatitis (VCD) is a common problem presenting as vulvar pruritus, burning or irritation. Its estimated prevalence is 20-30% in vulvar clinics, but the prevalence in the general population is unknown. Contact dermatitis is an inflammation of the skin resulting from an external agent that acts as an irritant or as an allergen. The skin reaction may be acute, subacute or chronic, resulting from prolonged exposure to weak irritating substances. The most common form of VCD is irritant contact dermatitis, and it usually presents as vulvar itch. The causes that contribute to VCD are increased sensitivity of the vulvar skin to irritants compared to other body parts, decrease in the skin barrier function due to exposure to sweat, urine and vaginal discharge and constant friction of the vulvar area. In menopausal women, lack of estrogen contributes to tissue atrophy and thinning, and may increase the effect of irritants on the vulvar skin. One of the most common irritating substances that cause VCD is urine. The phenomenon of urine-induced VCD is known as" diaper rash" in babies, and it was also described in bedridden patients using diapers constantly. Women with urine incontinence (UI), a problem that its prevalence in women increases with aging, may use constantly panty liners or pads to prevent urine leakage. The urine is being absorbed in the pad, and the vulvar skin is continually exposed to urine. This can cause VCD, similar to diaper rash. The prevalence of this phenomenon in the general population is unknown. The patients complain of itch, burning or irritation of the vulvar skin, and on exam erythema, edema and irritated skin are found. As most patients do not connect between UI to their vulvar disorder, and as most care-givers do not ask routinely about UI, the vulvar symptoms are mistakenly attributed to yeast infection or other factors. As the cause to the vulvar complaints is not recognized, patients do not receive proper treatment that requires primary management of UI. The aim of the study is to evaluate the prevalence of VCD in women with UI and to recognize risk factors for UI induced VCD.

Mycosis Fungoides (MF) is a rare malignancy in the United States. It is the most common form of cutaneous T-cell lymphoma (CTCL). Sézary syndrome (SS) is the most severe and leukemic form of CTCL. Pruritus, or itch, is defined as an unpleasant sensation that elicits the desire to scratch. Severe itch is a manifestation of all forms of MF, especially those with patch/plaque and folliculotropic variants, as well as in Sezary patients. While severe itch causes great suffering for patients, the pathogenesis of itch in MF and Sezary syndrome is complex and not well understood. It is thought that various chemical mediators are produced by the malignant cells to cause itch. Vorinostat, an FDA approved therapy for the treatment of MF, has also been reported to relieve pruritis. The goal of the study is to evaluate how vorinostat affects different chemicals in the skin that have been known to cause itch. This is a single center, non-randomized study designed to obtain and test blood and skin tissue samples take at various time-points over 6 months in patients who are prescribed vorinostat per standard of care treatment. Samples from pruritic and non-pruritic skin and blood of MF and Sezary patients will be evaluated for the presence of chemicals thought to be important in the cause of itch in these diseases. This evaluation will include immunohistochemistry, RT-PCR, and ELISA assays. The results from this study may help define how vorinostat decreases itch in patients with MF and Sezary Syndrome.

The primary objective of this observational study is to describe the prevalence of pruritus and pemphigoid in nursing home patients. Secondary outcomes are the relationships of demographic factors and medical risk factors with pemphigoid, including dementia and neuropsychiatric symptoms, medication use and Karnofsky score.

Work stress and pruritus: imbalance of effort balance reward in patients with psoriasis.

Pediculosis capitis is a parasitic infestation that can cause scalp pruritus and quality of life disturbances. There are two objective measurement for pruritus, visual analog scale (VAS) and 5-D itch scale, which can assess the severity of the scalp pruritus and the latter can also asses the quality of life affected by pruritus. Even though VAS can not be used to evaluate the impact of pruritus on quality of life, it is very easy to use while 5-D itch scale is complex and not child-friendly. The aim of this study is to determine the relationship between two different pruritus scales and to establish validity of pruritus VAS scale in evaluating quality of life in children with pediculosis capitis. We compare two pruritus scale on students with pediculosis of two boarding school in Bogor, West Java, Indonesia.

Systemic sclerosis (SSc) has heterogeneous symptoms and significant medical morbidity. Recently, itch was described as a symptom of SSc (prevalence of 42,6%). To the investigators knowledge, no study yet has examined the clinical features of itch neither had used a specific itch-related quality of life (QoL) scales in patients with SSc. The objectives were to evaluate the prevalence of pruritus, its characteristics and its impact on the QoL in those patients. In this descriptive study, patients followed for SSc in the departments of dermatology, rheumatology, internal medicine and pulmonology at the University Hospital of Brest were included. Participants received a questionnaire including questions about the clinical features of pruritus and 2 scores (5-D itch scale, ItchyQol).

We believe that knowing characteristics of uremic pruritus is the foundation to investigate its pathophysiology and offer better skin care for patients with chronic kidney disease. We therefore conducted this cross-sectional study to evaluate the characteristics of uraemic pruritus.

The purpose of this study is to investigate the prevalence of depression, anxiety, and sleep problems in patients with chronic skin diseases in dermatology clinics at the University of Wisconsin Hospital and Clinics.
