The Immunogenetics of Granulomatous Diseases.

Adv Exp Med Biol 2022 ;1367:349-368

Department of Dermatology, Mersin University, Mersin, Turkey.

Non-infectious granulomatous skin diseases are a wide category of well-defined reactive inflammatory conditions that share main similarities. While cutaneous sarcoidosis is the prototype of non-infectious (sterile) granulomatous dermatitides, there are several other entities in this group including granuloma annulare and necrobiosis lipoidica. Non-infectious granulomatous diseases are caused by complex associations between genetic situations and environmental triggers resulting in a variety of cutaneous and systemic manifestations.

Skin anomalies in acromegalic patients (Review of the practical aspects).

Exp Ther Med 2021 Nov 20;22(5):1330. Epub 2021 Sep 20.

Department of Endocrinology, 'Carol Davila' University of Medicine and Pharmacy, 050474 Bucharest, Romania.

Acromegaly is a hormonal disorder which occurs as the result of growth hormone (GH) and insulin growth factor 1 (IGF-1) over-secretion; both hormones are related to skin anomalies. The skin acts as a large endocrine organ, hosting GH receptors in every cell while IGF-1 receptors are expressed only in keratinocytes. This review is a literature review of skin anomalies found in acromegaly, either related to the disease itself or associated with related complications such as secondary diabetes mellitus, or involving associated conditions such as genetic syndromes.

Cutaneous Manifestations of Nutritional Excess: Pathophysiologic Effects of Hyperglycemia and Hyperinsulinemia on the Skin.

Cutis 2021 Feb;107(2):74-78

Mr. Svoboda is from the Virginia Tech Carilion School of Medicine, Roanoke. Dr. Shields is from the Department of Dermatology, University of Wisconsin School of Medicine and Public Health, Madison.

Hyperglycemia is defined by excess blood glucose and, when persistent, may lead to prediabetic and diabetic states. Insulin is a hormone produced by the beta cells of the pancreas in response to elevated blood glucose. Dysregulated insulin secretion or clearance results in hyperinsulinemia, which also is closely associated with type 2 diabetes mellitus (T2DM) and metabolic disturbances. Read More
