Acanthosis nigricans and hyperandrogenism are commonly found in patients with extreme target cell resistance to insulin, as in the type A and B syndromes of insulin resistance. However, the significance of concurrent acanthosis nigricans and hyperandrogenism in other clinical settings is not clear.
OBJECTIVE
To clarify the clinical significance of acanthosis nigricans (AN) and the association of gene polymorphisms in the ss2- and ss3-adrenergic receptors (B2ADR and B3ADR) in Japanese obese children and adolescents.
METHODS
Seventy obese subjects (56 boys, 14 girls) from 5 to 19 y of age were
Acanthosis nigricans is prevalent in the general population and is the most common dermatological manifestation of obesity. It is typically observed in the flexural areas such as the neck, axillae, and groin. Herein we report an interesting case of extensive acanthosis nigricans involving the neck,
BACKGROUND
Screening for acanthosis nigricans (AcN) in overweight children is repeatedly recommended. The significance of AcN, and its relation to central obesity in children, is unclear.
OBJECTIVE
To compare clinical and anthropometric parameters associated with adiposity, between overweight and
We report a case of a morbidly obese 32-year-old man presenting with acanthosis nigricans in the setting of Duke's B adenocarcinoma of the hepatic flexure.
Acanthosis nigricans (AN) is a hyperpigmented dermatosis associated with obesity and insulin resistance (IR). There is no consensus whether AN extension scoring offers added value to the clinical estimation of IR. In this study we aimed to assess and score AN using both a short and an This longitudinal study examined the rates of overweight, elevated blood pressure, acanthosis nigricans, and their associated factors in third through fifth grade students over 4 years. Participants consisted of 279 students who participated in health screenings in 2002 and 2006. Hispanic students
OBJECTIVE
Acanthosis nigricans (AN) is proved to be a skin phenotype of hyperinsulinemia especially in obese patients. Irisin is a new myokine which plays an important role in metabolic disorders, such as obesity, insulin resistance, and type 2 diabetes. The role of irisin in the development of
OBJECTIVE
The prevalence of obesity and of type 2 diabetes mellitus in children have increased in the Chinese population over the past two decades, and thus diabetes prevention has become a major concern of public health agencies. Identification of individuals at risk for diabetes is an essential
BACKGROUND
Acanthosis nigricans (AN) is a skin condition characterized by darkening and thickening of skin with formation of irregular folds, usually limited to a few specific areas of the body. Recently, AN has been reported to be linked to hyperinsulinemia and obesity. The aim of the present study
Objective. We aimed to investigate the relationship between FGF21 and obesity-related acanthosis nigricans (AN). Methods. 40 obese patients without AN (OB group), 40 obese patients with AN (AN group), and 40 healthy volunteers (control group, CON) were included in this study. Weight, BMI, lipid
Acanthosis nigricans (AN) is most commonly related to obesity as a manifestation of cutaneous insulin resistance in children and adolescents, while the interaction and time course between AN and obesity and detailed mechanism for the pre- and co-obese appearance of AN (PCOAN) in child are unclear.
Acanthosis nigricans is characterized by hyperpigmented velvety plaques of body folds and neck. Insulin could be a responsible factor in the pathogenesis of this condition and hyperinsulinemia: a consequence of insulin resistance stimulates the formation of these characteristic plaques. In this
Acanthosis nigricans (AN) is characterized by symmetric, velvety, gray-brown hypertrophied plaques most commonly on the axillae and neck. Confluent and reticulated papillomatosis (CRP) is manifested by papules in the mid-chest that coalesce in the midline, and are arranged in a reticulated pattern
OBJECTIVE
The strong relation between type 2 diabetes mellitus and obesity with acanthosis nigricans is widely concerned. This study investigated the pancreatic beta-cell function in obese children with acanthosis nigricans, so as to find out the role of insulin secretion and insulin resistance in
