Mucilage is a sticky substance found in various plants and microorganisms and is made up of proteins and polysaccharides. Mucilage fromis a complex polysaccharide traditionally used to treat different skin diseases. In our study, we fabricated mucilage polymer fromleaves and evaluated its potential application in second-degree burns and excision wounds. The physical properties of Hibiscus mucilage (HM) polymer were demonstrated by using Ultraviolet-visible absorption spectroscopy, x-ray diffraction, Fourier transform infrared spectroscopy, dynamic light scattering, Scanning electron microscopy, Brunauer-Emmett-Tellerand, Swelling ratio. The human cell lines WI-38, and HaCaT have been used forexperiments like MTT, scratch wound, BrdU, ROS scavenging assays, and western blot analysis. The results of the MTT, scratch-wound, and BrdU assay indicated that the HM polymer is nontoxic in nature and also enhances both the properties of cellular migration and proliferation, respectively. On the other hand, the result of the ROS scavenging assay suggested that HM polymer enhances the antioxidant activity of cells while the western blot analysis designated that the HM polymer treatment caused downregulation of the pro-inflammatory cytokine IFN-and upregulation of the pAkt (Serine 473) protein, and TGF-1 signaling pathway. Therefore, allexperimental studies recommended that HM polymer is biocompatible and has antioxidant and anti-inflammatory effects. In theexperiment, second-degree burns and excision wounds were created on the dorsal surface of male BALB/c mice. After the sixth day of HM polymer treatment have developed new tissue, hair follicles, blood vessels,-SMA, and Collagen type-1 fiber on the burn and excision wound area while the 11th day of HM polymer treatment cured the wound area significantly. Therefore, it could be contemplated that HM polymer is a potential agent for treating different wounds in the near future.

Purpose: The aim of the present study is to examine the demographic data and clinical features of ocular surface injuries due to thermal burns and to evaluate LSCD in the light of global consensus.
Methods: Thirty-three eyes of 20 cases with ocular surface injury due to thermal burn who attended to the clinic between 2012 and 2023 were included in the study. LSCD severity was staged according to the global consensus which was published in 2019.
Hidradenitis Suppurativa Surgery Complication Rates Among Patients With Obesity or Diabetes or Who Smoke: A Review.
JAMA Dermatol
January 2025
Department of Dermatology, School of Medicine, University of North Carolina at Chapel Hill.
Importance: Surgery is frequently required for hidradenitis suppurativa (HS) treatment, but the impact of common comorbidities such as obesity, diabetes, and smoking on outcomes has been sparsely studied.
Observations: A total of 12 studies met final inclusion criteria for investigating complication rates associated with at least 1 comorbidity. Complication rates were associated with obesity in 3 of 10 studies.
Biodegradable Temporizing Matrix in Postoncological Scalp Reconstruction: A Case Series.
Plast Reconstr Surg Glob Open
January 2025
From the Department of Plastic Surgery, Hull University Teaching Hospitals, East Riding of Yorkshire, United Kingdom.
Biodegradable temporizing matrix (BTM) is a synthetic biodegradable dermal matrix that helps develop a non-skin graft amenable wound bed (eg, over tendon or bone) into a graftable wound bed, by acting as an inert scaffold for angiogenesis and formation of granulation tissue. There is currently a paucity of evidence to encourage its use in scalp defects following skin malignancy excision. This retrospective analysis aimed to evaluate the utility of BTM in this patient subset.

Pilonidal sinus is a common pathology of the intergluteal cleft that can develop into abscess or suppuration. This lesion corresponds histologically to a granuloma that organizes around foreign bodies, most often hairs, and fistulizes to the skin through partially epithelialized orifices. If suppuration and abscess develop, treatment is based either on medical treatment combining analgesics, local antiseptics and sometimes antibiotics, or on emergency incision and drainage in the operating room.

Plast Reconstr Surg Glob Open
January 2025
From the Department of Plastic and Reconstructive Surgery, Beaumont Hospital, Dublin, Ireland.
Background: The use of PolyNovo NovoSorb biodegradable temporizing matrix (BTM) has become popular for the management of complex wounds, often with the subsequent application of a split-thickness skin graft. To date, there are no published case series describing healing via secondary intention over BTM in the management of small, complex nasal wounds following excision of skin malignancy in the elective setting.
Methods: This study consisted of a single-center, consecutive case series.
