Abstract
Background: Various studies have examined occlusive dressings in fingertip amputations and reported good outcomes. Occlusive dressing preserves appropriate pH, cell accumulation and moisture for healing, thereby limiting scar formation and deformity. To our knowledge, no study was performed in tropical Asia. This study aims to demonstrate the viability of healing fingertip amputations through secondary intention using an effective dressing technique, even in warm tropical climates. Methods: All patients who presented to our institution with fingertip amputations from 1 July 2020 to 31 July 2022 were analysed retrospectively. Seventeen patients (15 male, 2 female) of mean age 37.2 ± 9.4 years old with 18 injured digits were retrospectively analysed. Twelve (66.7%) were Allen Type III injuries, and one patient required distal phalangeal K-wire fixation. During the patient's final review, static 2-point discrimination, pulp sensation, fingertip contour and nail deformities alongside the last measured range of motion (ROM) of the injured finger was recorded. Treatment duration and days of leave taken were also summed and assessed. Results: Patients were dressed with semi-occlusive dressing for an average of 20.1 ± 6.83 days. The average total duration of dressing is 36.78 ± 18.88 days over an average of 7.18 ± 4.03 dressing visits. Mean duration of follow-up was 108 ± 63.46 days. Good outcome measures in sensation, pulp contour, nail deformity and ROM similar to existing literature were reported. Conclusions: Occlusive dressing remains a viable and feasible treatment option for fingertip amputation even in a tropical climate. While this simple treatment method may require more effort from patient, wound healing was attained after 36.8 ± 18.9 days of dressing. Level of Evidence: Level IV (Therapeutic).

Abstract
Background The aim of this prospective cohort was to evaluate the conservative treatment of fingertip amputation with exposed bone, with a semi-occlusive dressing. Methods Ten patients with an amputation distal to the distal interphalangeal joint were treated via secondary healing under a semi-occlusive film dressing. We followed up the patients weekly until the fingertip had healed, then a final clinical visit at 6 months, and a patient-reported outcome assessment at 2 years after the injury. Results All 10 patients completed the 6-month clinical follow-up, and seven patients completed the final patient-rated outcome assessments at 2 years. There were no complications during the study period, all the patients were satisfied with the results, and all answered "fully agree" on choosing the same treatment method again in a similar injury. Conclusion Our results show that conservative treatment of fingertip amputation is feasible and can provide good results.

Abstract
PURPOSE To analyze the influence of occlusive dressing on the healing of excisional skin wounds in mice. METHODS Pre-clinical, comparative, and translational study. Mice were divided into three experimental groups: wounds occluded with hydrocolloid (HD) dressings, transparent polyurethane film (TF) dressings, and without occlusion (WO), monitored at three, six and 14 days, with eight animals each. Closure rate, infiltration of neutrophils and macrophages, measurement of tumor necrosis factor-α (TNF-α) and vascular endothelial growth factor (VEGF) and, histologically, angiogenesis were evaluated. RESULTS Wound closure was accelerated in the occlusive groups. There was a decrease in TNF-α levels in the HD group when compared to the WO and TF groups. Neutrophils accumulation decreased in the HD group. Increased dosages of macrophages were evidenced in the HD group, compared to the WO and TF groups. Levels of VEGF were increased in the TF and HD groups. CONCLUSIONS It is suggested that the occlusion of wounds modulates the inflammatory response.

Abstract
Abstract
Objectives
Treatment of fingertip amputations is subject of controversial debates. Recently, semi-occlusive dressings have increased in popularity in these injuries.
Aims
To compare clinical outcomes of conservative semi-occlusive dressing therapy versus surgical treatment of fingertip amputations.
Methods
Eighty-four patients with fingertip amputations were re-examined clinically after a mean follow-up of 28.1 months (range 9.6–46.2). Sixty-six patients (79%) were treated with semi-occlusive dressings (group 1) and 18 (21%) underwent surgery (group 2). Range of motion, grip strength, and two-point discrimination were measured at the final follow-up. Furthermore, VAS score, Quick-DASH score, subjective aesthetic outcome and loss of working days were obtained.
Results
Group 1 demonstrated healing in all 66 patients (100%) while in Group 2 5 out of 18 patients (28%) failed to achieve healing after a mean of 17 days (range 2–38) due to graft necrosis. Group 1 showed significantly lower VAS scores and significantly lower loss of two-point discrimination compared to Group 2. Work absence was significantly shorter in Group 1 versus Group 2. Trophic changes in finger (46%) and nail (30%) were significantly lower in Group 1 compared to Group 2 (44% and 70%, respectively). Disturbance during daily business activities (14%) and cold sensitivity (23%) were significantly lower in Group 1 compared to Group 2 (86% and 77%, respectively).
Conclusions
Semi-occlusive dressing therapy for fingertip amputations demonstrated excellent healing rates. Compared to surgical treatment, it resulted in significantly better clinical outcomes, lower complication rates and significantly higher reported satisfaction rates. Therefore, semi-occlusive dressing for fingertip injuries is a very successful procedure and shall be preferred over surgical treatment in most cases.
Level of evidence
III therapeutic.

Front Pharmacol 2021; 12:690538. [PMID: 34276377 PMCID: PMC8277921 DOI: 10.3389/fphar.2021.690538] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2021] [Accepted: 06/16/2021] [Indexed: 11/23/2022] Open
Abstract
Dermal fibroblast replicative senescence that often occurs in aging skin is characterized by loss of cell proliferative capacity, cell cycle arrest, decreased cell elongation, and decreased synthesis of dermal extracellular matrix (ECM) components. Although Panax notoginseng is known for its effectiveness in alleviating many age-related degenerative diseases, few studies have evaluated P. notoginseng components for efficacy or mechanisms of action in delaying cell replicative senescence. In this study, P. notoginseng oligosaccharides (PNO) were isolated using a stepwise purification procedure involving water extraction and alcohol precipitation followed by DEAE Sepharose Fast Flow column chromatography, preparative high performance liquid chromatography, and size-exclusion chromatography. Monosaccharides detected in PNO constituents included mannose, galactose, and sorbitose in relative molar proportions of 14.2:12.3:1, respectively, aligning with PNO absorption spectrum results resembling typical known spectra for sugars. In vitro, PNO treatment of replicative senescent NIH-3T3 fibroblasts significantly promoted cell vitality, inhibited SA-β-galactosidase (SA-β-Gal) activity, and reduced p16 and p21 protein-level expression. Moreover, PNO treatment of senescent fibroblasts led to a lower proportion of G1 phase cells and higher proportion of S phase cells, while also inducing aging NIH-3T3 cells to migrate and synthesize collagen-I (CoL-I). Mechanistically, PNO treatment up-regulated expression of proliferating cell nuclear antigen (PCNA), cyclin E, cyclin D1, and cyclin-dependent kinase 4 (CDK4) proteins and promoted phosphorylation of MEK, p38, and ERK1/2 to trigger cell cycle progression. Additionally, PNO treatment also up-regulated protein-level expression of TGF-β1 and levels of p-Smad2/3, p-FAK, and p-Pax to trigger CoL-I synthesis and cell migration. Taken together, these findings demonstrate that oligosaccharides purified from P. notoginseng could reverse fibroblast replicative senescence by promoting fibroblast cell proliferation, migration, and CoL-I production.

Abstract
Skin injury is quite common, and the wound healing is a complex process involving many types of cells, the extracellular matrix, and soluble mediators. Cell differentiation, migration, and proliferation are essential in restoring the integrity of the injured tissue. Despite the advances in science and technology, we have yet to find the ideal dressing that can support the healing of cutaneous wounds effectively, particularly for difficult-to-heal chronic wounds such as diabetic foot ulcers, bed sores, and venous ulcers. Hence, there is a need to identify and incorporate new ideas and methods to design a more effective dressing that not only can expedite wound healing but also can reduce scarring. Calcium has been identified to influence the wound healing process. This review explores the functions and roles of calcium in skin regeneration and reconstruction during would healing. Furthermore, this review also investigates the possibility of incorporating calcium into scaffolds and examines how it modulates cutaneous wound healing. In summary, the preliminary findings are promising. However, some challenges remain to be addressed before calcium can be used for cutaneous wound healing in clinical settings.

Analysis of Rinsing Fluid during Negative Pressure Wound Therapy with Instillation: A Potential Monitoring Tool in Acute and Chronic Wound Treatment. A Pilot Study. Cells 2021; 10:cells10040732. [PMID: 33810232 PMCID: PMC8065450 DOI: 10.3390/cells10040732] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2021] [Revised: 03/20/2021] [Accepted: 03/25/2021] [Indexed: 11/16/2022] Open
Abstract
Background: During negative pressure wound therapy (NPWT), open wounds are draped with a nontransparent sponge, making daily wound evaluation impossible. Sometimes, late or undetected bacterial infections and postoperative bleeding result in repetitive surgery, thus prolonging inpatient time. With the introduction of additional fluid instillation (NPWTi), the wound surface is rinsed, and bacteria, proteins and biomarkers are flushed into a collecting canister, which is later discarded. Methods: The aim of this pilot study was to analyze rinsing fluid samples (0.9% sodium chloride) from the NPWTi device in patients with acute and chronic wounds. In 31 consecutive patients a standardized laboratory analysis was performed to evaluate cellular composition and potassium, phosphate, lactate dehydrooxygenase, pH and total protein levels. Results: While there was an increase in the total cellular amount and the number of polymorphonuclear cells, the number of red blood cells (RBC) decreased after surgery. Potassium and pH showed no significant changes in the first three postoperative days, whereas total protein showed an undulant and partially significant course. Conclusion: We were able to quantify cellular metabolites by analyzing the rinsing fluid of NPWTi. We propose the analysis of this material as a novel and potentially promising tool to monitor wound status without removal of the dressing. The establishment of reference values might help to improve the NPWTi therapy.

Abstract
Stem cell-based products are rapidly emerging in the marketplace as topical skin care and wound care products. Confusion is prevalent among healthcare providers and end-users about these products. Adipose-derived stem cells, fibroblasts, platelets, and bone marrow-derived stem cells are the most common cells used for stem cell therapeutic development, medical procedures, and skin care products. In this review, the significant advantages of adipose-derived stem cells and fibroblasts in terms of safety and efficacy are highlighted and compared to relatively risky platelets and bone marrow stem cells.
