Galunisertib Exerts Antifibrotic Effects on TGF-β-Induced Fibroproliferative Dermal Fibroblasts.

Int J Mol Sci 2022 Jun 15;23(12). Epub 2022 Jun 15.

Department of Surgery, University of Texas Medical Branch, Galveston, TX 77555, USA.

Dermal fibroblasts in pathological scars secrete constitutively elevated levels of TGF-β, signaling the transcription of fibrotic genes via activin-like kinase 5 (ALK5). In the present study, we examine the antifibrotic effects of galunisertib, a small-molecule inhibitor of ALK5, on fibroproliferative dermal fibroblasts in an in vitro model of wound healing. We induced fibrosis in human dermal fibroblasts with exogenous TGF-β and performed cellular proliferation assays after treatment with varying concentrations of galunisertib. Read More

Resurfacing of Face and Neck Using Superthin Thoracodorsal Artery Perforator Free Flaps.

J Craniofac Surg 2022 May 1;33(3):931-934. Epub 2021 Oct 1.

Department of Plastic and Reconstructive Surgery, College of Medicine, Hanyang University, Seoul, South Korea.

Background: Resurfacing of facial and neck defects is challenging due to the unique skin color, texture, and thickness of the region. With the development of microsurgical reconstruction, perforator- free flaps can provide adequate soft tissue. However, despite various modifications, such flaps hardly satisfy cosmetic requirements, due to differences in color and bulkiness. Read More

Use of Serial Flap Transfer Technique in En Bloc Reconstruction of Extensive Soft Tissue Defects in the Head and Neck.

J Craniofac Surg 2022 May 12;33(3):809-813. Epub 2021 Apr 12.

Department of Plastic and Reconstructive Surgery, Plastic Surgery Hospital, Chinese Academy of Medical Sciences, Peking Union Medical College, Shijingshan District, Beijing, china.

[Stereotactic radiotherapy with CyberKnife and linear accelerator in the management of malignant melanoma].

Magy Onkol 2022 Jun 28;66(2):127-133. Epub 2022 May 28.

Onkodermatológiai Osztály, Országos Onkológiai Intézet, Budapest, Hungary.

Stereotactic radiotherapy gains more and more importance in the management of malignant melanoma, owing to technical developments of recent years. This approach might be applied with success in solitary or oligometastatic cases, since the deliverable biological dose is far higher than that of conventional radiotherapy. Beyond chemotherapy of decreasing importance, there is a widening range of new targeted and immunotherapy agents, leading to longer survival times even in disseminated stages. Read More

BMC Neurol 2022 Jun 18;22(1):223. Epub 2022 Jun 18.

Department of Neurosurgery, Nagoya University Graduate School of Medicine, 65 Tsurumai-cho, Showa-ku, Nagoya, Aichi, 466-8550, Japan.

Background: Eccrine spiradenocarcinoma (SC), also known as malignant eccrine spiradenoma, is a rare malignant cutaneous adnexal neoplasm arising from long-standing benign eccrine spiradenoma. Malignant skin tumors rarely show direct intracranial invasion. However, once the intracranial structure is infiltrated, curative excision with sufficient margins can become extremely difficult, particularly when the venous sinuses are involved. Read More

Controlling Inflammation Pre-Emptively or at the Time of Cutaneous Injury Optimises Outcome of Skin Scarring.

Front Immunol 2022 27;13:883239. Epub 2022 May 27.

Plastic and Reconstructive Surgery Research, National Institute for Health Research (NIHR) Manchester Biomedical Research Centre, University of Manchester, Manchester, United Kingdom.

Inflammation plays an active role during the wound healing process. There is a direct association between the extent of injury as well as inflammation and the amount of subsequent cutaneous scarring. Evidence to date demonstrates that high levels of inflammation are associated with excessive dermal scarring and formation of abnormal pathological scars such as keloids and hypertrophic scars.

FACELIFT TECHNIQUES: AN OVERVIEW.

Facial Plast Surg 2022 Jun 16. Epub 2022 Jun 16.

Facial Plastic Surgery, FACEISTANBUL, istanbul, Turkey.

Facelift techniques can be classified according to the depth and extent of the dissection applied. Imbrication and plication of the SMAS referred to as "SMAS lifts" or "classical facelifts" are the most commonly used techniques. Plication techniques involve in-folding of the SMAS and suture suspension without any SMAS incision whereas imbrication techniques involve a SMAS incision with a portion of the SMAS either removed or transposed with or without limited subSMAS dissection.

Does Residual Invasive Disease in Wide Local Excision after Diagnosis with Partial Biopsy Technique Influence Survival in Melanoma? Matched-Pair Analysis of Multicenter Selective Lymphadenectomy Trial I and II.

J Am Coll Surg 2022 Jul 5;235(1):49-59. Epub 2022 May 5.

From Saint John's Cancer Institute at Providence Saint John's Health Center, Santa Monica, CA.

Background: Current guidelines recommend excisional/complete biopsy for melanoma diagnosis, owing to high rates of residual disease found at wide local excision (WLE) after partial biopsy techniques. We sought to determine any survival disadvantage associated with the presence of residual invasive melanoma in the WLE after diagnosis with a partial biopsy technique.

Study Design: Data were examined from Multicenter Selective Lymphadenectomy Trials I and II (MSLT-I and -II), 2 large melanoma trials. Read More

Actas Dermosifiliogr 2022 May 31;113(5):491-497. Epub 2022 Jan 31.

Departamento de Dermatología, Instituto Valenciano de Oncología, Valencia, España.

Dermatologic surgery has 2main objectives: 1) to guarantee surgical radicality; and 2) to achieve optimal aesthetic and functional results. These 2paradigms and their hierarchy must be considered when performing surgical procedures on the skin. Even the easiest intervention, the elliptical excision, presents some features that should be known to achieve such goals. Read More

scarless skin healing of a severe human burn wound induced by a hCTLA4Ig gene-transferred porcine skin graft.

Int J Med Sci 2022 21;19(5):952-964. Epub 2022 May 21.

Department of Burns and Plastic Surgery, the First Affiliated Hospital of Shenzhen University, Shenzhen Second People's Hospital, Shenzhen, P.R. China.

Preventing fibrosis or hypertrophic scar formation following tissue damage is still a big challenge despite the numerous approaches clinicians currently use. Hitherto, no written account was available of a successful case of scarless skin healing after a severe burn injury. Here, we report the first case of the "perfect regenerative healing" of a severe burn wound with no hypertrophic scar formation in which a postage stamp skin autograft was covered with human cytotoxic-T-lymphocyte associated antigen4-immunoglobulin (hCTLA4Ig) gene-transferred pig skin.

Higher proportions of CD39+ tumor-resident cytotoxic T cells predict recurrence-free survival in patients with stage III melanoma treated with adjuvant immunotherapy.

J Immunother Cancer 2022 Jun;10(6)

Melanoma Institute Australia, The University of Sydney, Sydney, New South Wales, Australia

Background: Adjuvant immune checkpoint inhibitor (ICI) immunotherapies have significantly reduced the recurrence rate in high-risk patients with stage III melanoma compared with surgery alone. However, 48% of anti-PD-1-treated patients will develop recurrent disease within 4 years. There is a need to identify biomarkers of recurrence after adjuvant ICI to enable identification of patients in need of alternative treatment strategies. Read More

Cutaneous Melanomas: A Single Center Experience on the Usage of Immunohistochemistry Applied for the Diagnosis.

Int J Mol Sci 2022 May 25;23(11). Epub 2022 May 25.

Pathology Unit, IRCCS Azienda Ospedaliero-Universitaria di Bologna, Policlinico di Sant'Orsola, 40139 Bologna, Italy.

Cutaneous melanoma (cM) is the deadliest of all primary skin cancers. Its prognosis is strongly influenced by the stage at diagnosis, with early stages having a good prognosis and being potentially treatable with surgery alone; advanced stages display a much worse prognosis, with a high rate of recurrence and metastasis. For this reason, the accurate and early diagnosis of cM is crucial-misdiagnosis may have extremely dangerous consequences for the patient and drastically reduce their chances of survival. Read More
