Characterizing the presence of neutrophil extracellular traps in neutrophilic dermatoses.

Exp Dermatol 2021 May 9. Epub 2021 May 9.

Department of Dermatology, American University of Beirut Medical Center, Beirut, Lebanon.

Neutrophil extracellular traps (NETs) are implicated in the pathogenesis of multiple inflammatory dermatoses. However, characterization of NETs in neutrophilic dermatoses was performed on very limited number of patients; this limitation precluded definitive conclusions. In this case series of 57 patients, we compared the amounts of neutrophils producing NETs in cutaneous lesions of different entities of neutrophilic dermatoses (17 with pyoderma gangrenosum, 37 with Sweet's syndrome and three with subcorneal pustular dermatosis).

Changes in peri-ocular anatomy and physiology in pseudoexfoliation syndrome (Review).

Exp Ther Med 2021 Jun 19;21(6):650. Epub 2021 Apr 19.

Laboratory of Clinical Virology, Medical School, University of Crete, Heraklion 71003, Greece.

Pseudoexfoliation syndrome (PEX) is characterized by the deposition of proteinaceous material in the anterior ocular segment (resulting in ophthalmic pathologies such as glaucoma and increased risk of complications in cataract surgery), but also by several systemic manifestations. The involvement of peri-ocular tissues in PEX, including the eyelid skin, lacrimal gland, conjunctiva, orbital fat and vessels, as well as the optic nerve, has been reported by several previous studies. The peri-ocular effects of PEX include the development of eyelid laxity, conjunctival chalasis, tear film abnormalities, pronounced orbital fat atrophy in response to the administration of prostaglandin analogues in pseudoexfoliative glaucoma, deficient orbital vascular supply and biomechanical changes in both the eyeball and the optic nerve.

Key indicators of repetitive overuse-induced neuromuscular inflammation and fibrosis are prevented by manual therapy in a rat model.

BMC Musculoskelet Disord 2021 May 5;22(1):417. Epub 2021 May 5.

Department of Anatomy and Cell Biology, Lewis Katz School of Medicine, Temple University, 3500 North Broad Street, Philadelphia, PA, 19140, USA.

Background: We examined the effectiveness of a manual therapy consisting of forearm skin rolling, muscle mobilization, and upper extremity traction as a preventive treatment for rats performing an intensive lever-pulling task. We hypothesized that this treatment would reduce task-induced neuromuscular and tendon inflammation, fibrosis, and sensorimotor declines.

Methods: Sprague-Dawley rats performed a reaching and lever pulling task for a food reward, 2 h/day, 3 days/week, for 12 weeks, while simultaneously receiving the manual therapy treatment 3 times per week for 12 weeks to either the task-involved upper extremities (TASK-Tx), or the lower extremities as an active control group (TASK-Ac).

Ovine model of burn wounds grafted with ovine cadaver skin.

Burns 2021 Mar 30. Epub 2021 Mar 30.

Department of Anesthesiology, University of Texas Medical Branch, Galveston, TX, USA; Shriners Hospitals for Children, Galveston, TX, USA. Electronic address:

Shortage in autograft to cover burn wounds involves a frequent use of cadaver skin (CS) as a temporary cover to prevent infection, dehydration and preparation of wounds for subsequent autografting. We aimed to establish an ovine model of burn wound healing using ovine CS (OCS). Quality and efficacy of fresh and frozen OCS overlaid on to excised 3rd degree flame burn wounds in sheep were evaluated in comparison to autograft. Read More

Elevated APOBEC mutational signatures implicate chronic injury in etiology of an aggressive head-and-neck squamous cell carcinoma: a case report.

J Med Case Rep 2021 Apr 30;15(1):252. Epub 2021 Apr 30.

Department of Dermatology, University of California, San Francisco, CA, 94115, USA.

Background: Aggressive squamous cell carcinomas (SCCs) present frequently in the context of chronic skin injury occurring in patients with the congenital blistering disease recessive dystrophic epidermolysis bullosa. Recently, these cancers were shown to harbor mutation signatures associated with endogenous deaminases of the active polynucleotide cytosine deaminase family, collectively termed APOBEC, and clock-like COSMIC [Catalogue of Somatic Mutations in Cancer] signatures, which are associated with normal aging and might result from cumulative DNA replication errors. We present a case of a nasal septal SCC arising in the context of recurrent injury, but also modest past tobacco use. Read More

An enzyme-responsive Gp1a-hydrogel for skin wound healing.

J Biomater Appl 2021 Apr 28:8853282211012870. Epub 2021 Apr 28.

Jiangsu Medical Engineering Research Center of Gene Detection and Department of Forensic Medicine, Xuzhou Medical University, Xuzhou, China.

Faster recovery and fewer scars are ideal wound healing. We have demonstrated that the cannabinoid receptor 2 (CB) agonist Gp1a is beneficial to skin wound healing, which inhibits inflammation and fibrogenesis while promoting re-epithelialization. However, the systemic administration is imprecise and overqualified for a local skin wound. Read More

Revisiting the Pericranial Flap for Scalp Reconstruction.

J Craniofac Surg 2021 May;32(Suppl 3):1275-1280

Division of Plastic, Aesthetic and Reconstructive Surgery, University of Miami, Miami, FL.

Abstract: Soft tissue deficits of the scalp due to trauma, infection, or tumor resection present a unique challenge to the reconstructive surgeon whose goal is to achieve excellent cosmesis in a hair bearing area without compromising coverage. While extensive undermining for large rotation flaps or free tissue transfer can provide necessary coverage, the pericranial flap is an excellent alternative for less ideal surgical candidates who cannot tolerate more extensive interventions or for patients who require long-term cancer surveillance. Elevation of the pericranial flap limits the need for back cuts through the skin and uses blunt dissection to preserve overlying hair follicles. Read More

Vopr Kurortol Fizioter Lech Fiz Kult 2021 ;98(2):45-54

Skin and venereal clinic N4, St.-Petersburg, Russia.

The scope of physical methods for correcting the pathological skin scars is rapidly growing but the results of their use are often unsatisfactory. An inadequate approach to therapy without taking into account the assessment of their effectiveness leads to relapses, increased growth of scar tissue or the absence of a clinically significant effect which requires strict scientific evidence in the course of benign scientific studies.

Objective: Scientometric analysis of evidence-based studies on the use of therapeutic physical factors in the correction of post-acne scars. Read More
