Hair Transplantation Follicular Unit Excision (FUE): Introducing the Multipurpose Octagonal Ring Punch.

J Cosmet Dermatol 2021 May 14. Epub 2021 May 14.

Division of Dermatology, Department of Medicine, University of Toronto School of Medicine, Toronto, Ontario, Canada.

The technique of follicular unit excision for harvesting grafts for hair transplantation procedures has become very popular. This technique relies on the use of small punches to remove viable grafts. Many different punch shapes have been developed to accommodate the varying nature of skin and hair characteristics, resulting in hair transplant surgeons requiring a variety of punches to suit a wide range of patients, which can be overwhelming to the beginner when trying to decide on the optimal choice of a punch to suit a particular skin characteristic.

A family with partially penetrant multicentric carpotarsal osteolysis due to gonadal mosaicism: First reported case.

Am J Med Genet A 2021 May 14. Epub 2021 May 14.

Department of Twin Research and Genetic Epidemiology, School of Life Course Sciences, Faculty of Life Sciences and Medicine, King's College London, London, UK.

Multicentric carpotarsal osteolysis (MCTO) is an autosomal dominant condition characterized by carpal-tarsal abnormalities; over half of affected individuals also develop renal disease. MCTO is caused by mutations of MAFB; however, there is no clear phenotype-genotype correlation. We describe the first reported family of variable MCTO phenotype due to mosaicism: the proband had classical skeletal features and renal involvement due to focal segmental glomerulosclerosis (FSGS), and the father had profound renal impairment due to FSGS, necessitating kidney transplantation.

Narrative review of facial gender surgery: approaches and techniques for the frontal sinus and upper third of the face.

Ann Transl Med 2021 Apr;9(7):606

Department of Plastic and Reconstructive Surgery, Johns Hopkins University School of Medicine, Baltimore, MD, USA.

Facial gender confirmation surgery (FGCS) is a series of procedures which seek to harmonize a patient's face with his/her self-image and gender identity. Originally described in San Francisco in the 1980s, FGCS has evolved to encompass all elements of the craniofacial skeleton and facial soft tissue. This field in plastic and reconstructive surgery has quickly gained more attention in the past decade due to the pioneering work of groups around the world along with increased social acceptance and medical care of the transgender community.

Design of In Vitro Hair Follicles for Different Applications in the Treatment of Alopecia-A Review.

Biomedicines 2021 Apr 16;9(4). Epub 2021 Apr 16.

Faculty of Medicine, Institute of Biomedical Sciences, University of Maribor, SI-2000 Maribor, Slovenia.

The hair research field has seen great improvement in recent decades, with in vitro hair follicle (HF) models being extensively developed. However, due to the cellular complexity and number of various molecular interactions that must be coordinated, a fully functional in vitro model of HFs remains elusive. The most common bioengineering approach to grow HFs in vitro is to manipulate their features on cellular and molecular levels, with dermal papilla cells being the main focus. Read More

Genomic and anatomical comparisons of skin support independent adaptation to life in water by cetaceans and hippos.

Curr Biol 2021 Mar 27. Epub 2021 Mar 27.

Division of Vertebrate Zoology and Sackler Institute for Comparative Genomics, American Museum of Natural History, New York, NY 10024, USA. Electronic address:

The macroevolutionary transition from terra firma to obligatory inhabitance of the marine hydrosphere has occurred twice in the history of Mammalia: Cetacea and Sirenia. In the case of Cetacea (whales, dolphins, and porpoises), molecular phylogenies provide unambiguous evidence that fully aquatic cetaceans and semiaquatic hippopotamids (hippos) are each other's closest living relatives. Ancestral reconstructions suggest that some adaptations to the aquatic realm evolved in the common ancestor of Cetancodonta (Cetacea + Hippopotamidae). Read More

HaCaT‑conditioned medium supplemented with the small molecule inhibitors SB431542 and CHIR99021 and the growth factor PDGF‑AA prevents the dedifferentiation of dermal papilla cells .

Mol Med Rep 2021 May 24;23(5). Epub 2021 Mar 24.

The Key Laboratory of Pathobiology, Ministry of Education, College of Basic Medical Sciences, Jilin University, Changchun, Jilin 130000, P.R. China.

Hair loss, including alopecia, is a common and distressing problem for men and women, and as a result, there is considerable interest in developing treatments that can prevent or reverse hair loss. Dermal papillae closely interact with epidermal cells and play a key role during hair follicle induction and hair morphogenesis. As dermal papilla cells (DPCs) lose their hair‑inducing ability in monolayer cultures , it is difficult to obtain hair follicle structures following DPC transplantation . Read More

Research Laboratory Omics Technology, Institute of Fundamental Medicine and Biology, Kazan Federal University, 420008 Kazan, Russia.

Several methods for the stimulation of skin wound repair have been proposed over the last few decades. The most promising among them are gene and stem cell therapy. Our present experiments combined several approaches via the application of human umbilical cord blood mononuclear cells (hUCB-MC) that were transfected with pBud-165-2 plasmid (gene-cell therapy) and direct gene therapy using pBud-165-2 plasmid to enhance healing of full thickness skin wounds in rats.
