Ramaut Lisa, Hoeksema Henk, Pirayesh Ali, Stillaert Filip, Monstrey Stan
BACKGROUND: Patients who suffer from scars or wrinkles have several therapeutic options to improve the appearance of their skin. The available treatment modalities that provide desirable results are often overtly invasive and entail a risk of undesirable adverse effects. Microneedling has recently emerged as a non-ablative alternative for treating patients who are concerned with the aesthetic changes that result from injury, disease or ageing. OBJECTIVE: This review aims to evaluate the current evidence in the literature on microneedling...

BACKGROUND: Acne keloidalis nuchae (AKN) is a chronic scarring folliculitis which usually occurs in young adult males of African descent. Studies have suggested that AKN may be associated with other dermatologic conditions and even general medical disorders. The aim of this study was to identify cutaneous and extracutaneous associated disorders and to examine risk factors in our population for developing AKN. METHODS: The study was a retrospective, descriptive, and analytical study conducted at the Dermatology Outpatient department of the University Hospital of the West Indies...

Importance: The notion that systemic isotretinoin taken within 6 to 12 months of cutaneous surgery contributes to abnormal scarring or delayed wound healing is widely taught and practiced; however, it is based on 3 small case series from the mid-1980s. Objective: To evaluate the body of literature to provide evidence-based recommendations regarding the safety of procedural interventions performed either concurrently with, or immediately following the cessation of systemic isotretinoin therapy...

Keloids are characterized by excessive collagen deposition and growth beyond the edges of the initial injury, and cytokines may be related to their formation. The objective of this study was to evaluate the collagen fibers, analyze in situ expression of cytokines in keloid lesions, and compare to the control group. Results showed that there was a predominance of women and nonwhite and direct black ancestry. Keloid showed a significant increase in total and type III collagen. Significantly, the expression of mRNA for TGF-β in keloid was increased, the expressions of IFN-γ, IFN-γR1, and IL-10 were lower, and IFN-γR1 and TNF-α had no statistical difference...

Keloids are developed as fibrotic scar at the site of surgery or trauma and often enlarge beyond the original scar margins. Re-188 colloid coated customized patch was superficially fixed onto the lesion for 3 hrs. The same patch was reapplied on the lesion on third day for 3 hrs. The patients were followed up at 1, 3,6 and 12 months post treatment. The size and elevation of the keloid lesion was reduced after treatment. The total radiation dose from the patch (day-1 and day-3) was 100 Gy/mCi of Re-188. The radioactive patch treatment of keloids is noninvasive, painless and safe with prolonged outcome...

Whitney L Quong, Yasuji Kozai, Rei Ogawa
Keloids are a manifestation of a fibroproliferative scarring disorder of the skin and develop in response to dermal injury in patients with a susceptible background. Local, systemic, and genetic factors contribute to keloid susceptibility. These factors include tension on the edges of the wound, hormonal influences, and ethnicity, respectively. Castleman's disease is a rare lymphoproliferative disorder that is characterized by the unregulated overproduction of interleukin-6, which leads to systemic lymphadenopathy and constitutional inflammatory symptoms...

Keloids are benign tumors that originate from scar tissues, but they usually overgrow beyond the original wounds. In a three-month single-center clinical trial, 69 patients were randomly divided into three groups. Patients in group 1 were treated with intralesional injection of diprospan (2 mg betamethasone disodium phosphate and 5 mg betamethasone dipropionate in 1 ml) with one-month intervals for three months. Patients in groups 2 and 3 were injected with a combination of 0.5 ml 5-fluorouracil (5-FU; 25 mg/ml) and diprospan as above for three months also...

BACKGROUND: Keloids and hypertrophic scars are fibroproliferative disorders of dermal tissue after skin injury. Many clinical control studies have reported evidence that silicone gel is effective in preventing and alleviating hypertrophic scarring. Whether silicone gel sheeting prevents hypertrophic scars or keloids requires clear evidence of its clinical effectiveness. OBJECTIVE: This review investigated the effectiveness of silicone gel and silicone gel sheeting for the prevention of hypertrophic or keloid scarring in patients with newly healed wounds...

BACKGROUND: Arborizing vessels (AVs) are dermoscopically defined as telangiectasias with distinct treelike branching, and are a characteristic feature of basal cell carcinoma (BCC). However, AVs are observed in various conditions other than BCC. OBJECTIVE: The aim of this study was to investigate skin diseases showing AV and investigates dermoscopic differences between BCC and non-BCC. METHODS: Dermoscopic images showing AV were prospectively collected and classified into BCC/non-BCC...

For decades, low- and moderate-dose radiation therapy (RT) has been shown to exert a beneficial therapeutic effect in a multitude of non-malignant conditions including painful degenerative muscoloskeletal and hyperproliferative disorders. Dupuytren and Ledderhose diseases are benign fibroproliferative diseases of the hand/foot with fibrotic nodules and fascial cords, which determine debilitating contractures and deformities of fingers/toes, while keloids are exuberant scar formations following burn damage, surgery, and trauma...

BACKGROUND: Keloids are a dermal fibroproliferative scar of unknown etiology. There is no good animal model for the study of keloids, which hinders the development and assessment of treatments for keloids. METHODS: Human keratinocytes and dermal fibroblasts were isolated from 3 human skin tissues: normal skin, white scars, and keloids. A mixed-cell slurry containing keratinocytes and dermal fibroblasts was poured into a double chamber implanted on the back of NOD/Shi-scid/IL-2Rγnull mice...

Frontometaphyseal dysplasia (FMD) is caused by gain-of-function mutations in the X-linked gene FLNA in approximately 50% of patients. Recently we characterized an autosomal dominant form of FMD (AD-FMD) caused by mutations in MAP3K7, which accounts for the condition in the majority of patients who lack a FLNA mutation. We previously also described a patient with a de novo variant in TAB2, which we hypothesized was causative of another form of AD-FMD. In this study, a cohort of 20 individuals with AD-FMD is clinically evaluated...

Intralesional triamcinolone acetonide injection is indicated for multiple skin conditions such as keloid scars, alopecia areata, and hypertrophic lichen planus. Immediate hypersensitivity reaction remains uncommon. We report on a 24-year-old woman who had received multiple intralesional injections with triamcinolone acetonide (Kenacort) plus lidocaine for keloid scar treatment without any reaction for the previous 10 years. The immediate reaction occurred 15 minutes after injection, with numbness on her face and 5 minutes later with urticaria on her chest wall and upper extremities, together with hypotension (blood pressure of 90/60 mmHg)...

Dog-ear collection, Z-plasty, and W-plasty are often performed for excision of dumbbell-shaped keloids; however, these procedures require additional incisions or excision of normal skin. Thus, an S-shaped wound closure technique was performed. The keloid lesions were extralesionally excised above the deep fascia, and the wound edges were shifted in opposite directions along the major axis to form an S-shape. The incision was closed by applying deep fascial sutures, subcutaneous sutures, and superficial sutures...

The aim of the present study is to explore the effect of IL-6 gene polymorphisms on the development of keloid scar (KS) in the Chinese Han population. Genotyping of IL-6 was performed by the polymerase chain reaction (PCR), followed by restriction fragment length polymorphism assays (PCR-RFLP). Serum level of IL-6 was measured using enzyme-linked immunosorbent assay (ELISA). Results indicated that when the IL-6 -572 CC homozygote genotype was used as the reference group, the GG genotype was found to be associated with a significantly increased risk of KS (GG vs CC: OR = 2...

REVIEW
C Huang, L Liu, Z You, Y Zhao, J Dong, Y Du, R Ogawa
Hypertrophic scars/keloids are pathogenic scars that are characterized by collagen and fibroblast accumulation. The endothelia in the lesions are mechanosensitive and participate actively in the pathogenesis of these scars. The present review summarizes how endothelium responds to mechanical stimuli such as shear, stretch, and hydrostatic pressure. It also shows that in heart, liver, kidney, and lung fibrosis, endothelial dysfunctions (EDs) associate with changes in vascular tone, endothelial permeability, coagulation, and vasomodulation that result in inflammation, hypertension, and coagulation...

BotulinumtoxinA (BoNT-A) is now widely established for the main approved indication of reducing glabellar lines, and is also widely used off-label to improve the appearance of wrinkles and lines in other parts of the face. The number of aesthetic procedures continues to increase as the patient population becomes more diverse, in particular with increasing numbers of people of color and men. Further developments in treatment may continue to expand the audience for BoNT-A by making procedures more comfortable and by delivering a more natural, less static appearance...
