This study presented an association between premature hair graying (PHG) and metabolic risk factors in young Koreans. Waist circumference, blood pressure, and fasting blood sugar were higher and serum high-density lipoprotein cholesterol was lower in subjects with PHG. The prevalence of subjects who had two or more metabolic risk factors was higher in subjects with PHG than those without. It postulates that PHG can be considered as a clinical marker for evaluating patients at risk for metabolic syndrome.

Adult-onset immunodeficiency due to anti-interferon-γ autoantibody is an emerging acquired immunodeficiency with frequent skin manifestations. A retrospective chart review was conducted and identified 41 patients with the syndrome. Skin involvement was detected in 33 (80%) patients, 15 (45%) with infective skin diseases and 27 (82%) with reactive skin disorders. Reactive lesions were mostly neutr ...

Impaired sleep due to nocturnal pruritus is a common symptom in patients with chronic pruritus. However, there is no standardized, simplified instrument for assessing sleep-related problems in patients with chronic pruritus. After a literature search, we conducted 50 interviews with patients with chronic pruritus and tested 12 items most frequently used in routine sleep questionnaires. Afterwards, ...

Studies on pregnancy and birth outcomes in women with psoriasis are scarce and the findings inconsistent. The effect of maternal psoriasis and its severity on the risk of adverse pregnancy and birth outcomes was examined. A cross-national population-based cohort study was performed using prospectively collected data from Denmark and Sweden. Singleton births in women with psoriasis were identified ...

Pruritus is a frequent symptom in systemic sclerosis (SSc), with a prevalence of 40–65%, but its pathophysiology is poorly understood. This study investigated the immunological component of pruritus. Fifty-six patients with SSc responded to a standardized questionnaire regarding both SSc disease and pruritus characteristics. Among patients with SSc, those with pruritus did not display a particul ...

The association of hair greying with metabolic syndrome is not well known, while association with obesity and coronary artery disease has been suggested. A cross-sectional study was conducted to identify an association between premature hair greying and metabolic risk factors. Of the 1,929 young healthy subjects (1,067 men and 862 women), 704 (36.4%) were categorized in the premature hair greying ...

Neurofibromatosis 1 has various complications. To elucidate the frequency of neurofibromatosis 1-related major complications requiring medical intervention, a nationwide retrospective study was conducted of 3,530 patients with neurofibromatosis 1 registered from 2001 to 2014 in Japan. The ratio of certified patients requiring medical intervention (>stage 3) was 82%. Patients classified in the most ...

There is a lack of data evaluating the influence of hidradenitis suppurativa-related subjective symptoms on sleep quality. The aim of this study was to assess the influence of itch and pain on sleep quality in 108 patients with hidradenitis suppurativa compared with 50 controls. The Athens Insomnia Scale (AIS) and Pittsburgh Sleep Quality Index (PSQI) were used to evaluate a spectrum of sleep dist ...

Carbonic anhydrases are ubiquitously expressed enzymes that reversibly hydrate carbon dioxide to bicarbonate and protons. While the main function of carbonic anhydrases is to regulate pH and osmotic balance, their involvement in other physiological processes remains to be explored. This study analysed changes in mRNA and protein levels of carbonic anhydrase II in human primary keratinocytes treate ...

Bullous pemphigoid (BP) is characterized by substantial skin and blood eosinophilia as well as intensive pruritus. Since the pruritogenic cytokine interleukin (IL)-31 is increased in inflammatory skin diseases the aim of this study was to determine whether IL-31 plays a role in BP. Using immunofluorescence, IL-31 expression was analysed in eosinophils derived from blister fluids and skin from pati ...

Tofacitinib is a Janus kinase (JAK) inhibitor, which has shown efficacy in treating psoriasis. The mode of action of tofacitinib is not completely understood but it has been thought to be mediated by the inhibition of CD4+ T-cell activation. Here, we investigated whether the molecular targets of tofacitinib are expressed in keratinocytes, and whether tofacitinib can modulate the activity of the JA ...

The development of androgenetic alopecia is associated with a risk of developing cardiovascular diseases, but the association of alopecia areata with cardiovascular diseases in humans is largely unexplored. We measured the plasma level of two common cardiovascular disease markers, cardiac troponin I and C-reactive protein, in alopecia areata and androgenetic alopecia affected subjects. Also, we in ...

Acne vulgaris has been postulated to have a gastrointestinal mechanism; however, little is known about gut microbiota dysfunction in this condition. The aim of this cross-sectional study was to investigate whether the gut microbiota is altered in acne. Faecal bacterial diversity was analysed in 43 patients with acne and 43 controls, using hypervariable tag sequencing of the V3–V4 region of the 1 ...
