BACKGROUND
The clinical efficacy of Jinchuang Ointment, a traditional Chinese medicine (TCM), in treating chronic non-healing diabetic wounds has been demonstrated over the past decades. Both in vitro and in vivo angiogenic activities have been reported for its herbal ingredients, including dragon blood from the palm tree Daemonorops draco and catechu from Uncaria gambir Roxb. Additionally, crude extracts of dragon blood have exhibited hypoglycemic effects not only in animal studies but also in cell-based in vitro assays.
RESULTS
Our findings indicate that crude dragon blood extract promotes the differentiation of myoblasts into myotubes. Partially purified fractions of dragon blood crude extract significantly enhance the expression of muscle cell differentiation-related genes such as myoG, myoD, and myoHC. Our results also demonstrate that crude extracts of dragon blood can inhibit platelet-derived growth factor-induced PAI-1 expression in primary rat vascular smooth muscle cells, thereby favoring changes in hemostasis towards fibrinolysis. Consistent with previous reports, reduced expression of plasminogen activator inhibitor 1 (PAI-1) accelerates wound healing. However, further separation resulted in a significant loss of both activities, indicating the involvement of more than one compound in these processes. Stem cells play a crucial role in muscle injury repair. Neither dragon blood nor catechu alone stimulated the proliferation of human telomerase reverse transcriptase (hTERT)-immortalized and umbilical cord mesenchymal stem cells. Interestingly, the proliferation of both types of stem cells was observed when crude extracts of dragon blood and catechu were present together in the stem cell growth medium.
CONCLUSIONS
Dragon blood from D. draco offers multifaceted therapeutic benefits for treating chronic nonhealing diabetic wounds from various perspectives. Most drugs in Western medicine consist of small molecules with defined ingredients. However, this is not the case in TCM, as the activities of dragon blood reported in this study. Surprisingly, the activities documented here align with descriptions in ancient Chinese medical texts dating back to A.D. 1625.

Retinoids are used topically as well as orally, and the most commonly used oral retinoids are isotretinoin and acitretin. Mucocutaneous adverse effects are frequently seen with the use of systemic retinoids, the most common being cheilitis, which is dose-dependent and seen in almost all patients using it. To study the comparative effect of topical tacrolimus 0.1% ointment versus topical white soft petrolatum jelly in the treatment of cheilitis due to retinoids. A total of 26 patients with cheilitis post-treatment with isotretinoin were enrolled in this cross-sectional study conducted over a period of 6 months. They were randomized into two groups of 13 patients each to receive topical tacrolimus 0.1% ointment and soft petrolatum jelly twice daily, respectively. Patients were followed up weekly with clinical photographs. Resolution of cheilitis was assessed on the basis of photograph and ICGS score. About 84.6% of patients of group A and 53.8% of patients of group B showed resolution of symptoms within 1 week of treatment. A significant difference was seen in duration for complete cheilitis resolution and relapse rate in the two groups. Our study concludes that oral retinoid-induced cheilitis shows faster and more significant resolution with twice-daily topical tacrolimus 0.1% ointment application compared to twice-daily topical petrolatum jelly.

The increasing popularity of tattoo art, including facial cosmetic tattoos, has led to a growing societal acceptance of tattoos. However, complications such as lip inflammation following cosmetic lip tattoos remain a concern. This article presents the case of a 47-year-old Asian woman who experienced recurrent lip swelling, purulent discharge, and scarring after receiving lip tattoos. Despite previous treatment with corticosteroid injections yielding unsatisfactory results, the patient showed significant improvement with topical application of 2% Crisaborole, a phosphodiesterase-4 inhibitor. Crisaborole modulates intracellular cyclic adenosine monophosphate levels, thereby reducing tissue inflammation and swelling associated with chronic cheilitis. Additionally, pulse laser therapy was effective in addressing residual tattoo pigment and scar tissue. This case highlights the therapeutic challenges of managing chronic inflammatory diseases of the lips secondary to cosmetic tattoos and introduces Crisaborole as a promising treatment option, offering insights for managing similar conditions in the future.

A 72-year-old male with a history of systemic hypertension, asthma, chronic obstructive pulmonary disease (COPD), and hyperlipidemia presents with diffuse patches of cutaneous depigmentation. A shave biopsy of different regions of depigmented skin indicated vitiligo. The patient was prescribed Opzelura (ruxolitinib) 1.5% topical cream as well as tacrolimus 0.1% topical ointment for vitiligo. He also had a history of prostate cancer. A prostate biopsy revealed three sites of prostatic adenocarcinoma with a Gleason score of 6 and a Prostate Imaging-Reporting and Data System (PI-RADS) score of 2. The patient remained in active surveillance for prostate cancer without treatment, due to its low severity. A subsequent biopsy five years later revealed a decrease in prostate cancer prevalence, with cancer present in only one core and at a lower severity. The purpose of this case presentation is to discuss possible links between vitiligo and prostate cancer, as well as their shared mechanisms and pathways.

This case report aims to present the successful reconstruction of a nasal defect in a 56-year-old male patient who suffered a partial nasal amputation due to a domestic accident involving a grinding wheel. The reconstruction was carried out using a paramedian frontal flap in a two-stage surgical process. Initially, the flap was designed and customized to match the dimensions of the defect, with a pedicle width of approximately 1.5 cm vertically. The flap was elevated in a distal-to-proximal manner, starting with subcutaneous dissection and progressing to periosteal dissection proximally. Weekly dressing changes were made using fatty gauze and fusidic acid ointment. Four weeks postoperatively, the flap pedicle was divided, and the brow was repositioned. At the six-month follow-up, the patient showed satisfactory clinical outcomes with no functional complaints and was very pleased with the aesthetic result. Paramedian frontal flap reconstruction is a dependable technique for addressing nasal defects following traumatic amputation, providing favorable functional and aesthetic results. This case highlights the importance of careful surgical planning and technique in achieving successful facial reconstruction.

While typically low-risk, cutaneous squamous cell carcinoma (cSCC) can infrequently progress to metastatic disease with in-transit lesions, localized to the dermis or subcutaneous tissue between the primary tumor and draining regional lymph nodes. These lesions are associated with poor prognostic values, including decreased survival rates and increased risk of recurrence. We present the case of a 75-year-old male with cSCC and in-transit metastases on his scalp treated with the immune checkpoint inhibitor (ICI) pembrolizumab in conjunction with diphencyprone (DPCP), a topical hapten that induces a delayed-type hypersensitivity reaction in the skin. The patient was enrolled in a clinical trial (NCT05481658) that involved the twice-weekly application of DPCP 0.04% ointment to four of the in-transit metastases on his frontal scalp, concurrent with pembrolizumab 300 mg administered every three weeks. Following effective sensitization and a twelve-week treatment course, complete clearance of all lesions, DPCP-treated and non-DPCP treated, was achieved, with no adverse events. The immunologic profiles of the post-treatment biopsies were analyzed by TaqMan Low Density Array quantitative real-time polymerase chain reaction to measure immune marker gene expression. Relative to the non-DPCP-treated lesion, the DPCP-treated lesion demonstrated increased pro-inflammatory genetic markers and T-cell activation. This case represents the first reported instance of in-transit metastases of cSCC successfully treated with DPCP and an ICI. It highlights the potential safety and efficacy of DPCP with systemic immunotherapy for the management of in-transit metastases of cSCC in patients for whom surgery and radiation may be contraindicated.

Postepy Dermatologii I Alergologii Apr 2024Vitiligo is an immune-related skin disease. Cytokines regulate immune response and inflammation and are involved in the pathogenesis of vitiligo.
INTRODUCTION
Vitiligo is an immune-related skin disease. Cytokines regulate immune response and inflammation and are involved in the pathogenesis of vitiligo.
AIM
To assess the serum levels of pro-inflammatory cytokines pre- and post- systemic glucocorticoid treatment in patients with active vitiligo.
MATERIAL AND METHODS
We measured serum cytokine levels using the enzyme-linked immunosorbent assay in 31 patients with active vitiligo before and after treatment. All patients received systemic glucocorticoid (compound betamethasone injection) in combination with topical halometasone cream and tacrolimus ointment for 3 months. Twenty healthy controls were also examined. The cytokines measured included TNF-α, IL-1β, IL-6, IFN-γ, IL-2, IL-17, IL-10, IL-8, and CXCL10.
RESULTS
The serum levels of TNF-α, IL-1β, IL-6, IFN-γ, IL-2, IL-17, IL-8, and CXCL10 were significantly higher, and levels of IL-10 were lower in vitiligo patients compared to controls. Additionally, serum IFN-γ ( = 0.378; = 0.036), IL-17 ( = 0.426; = 0.017), and CXCL10 ( = 0.514; = 0.003) showed a positive correlation with affected body surface area in vitiligo patients. After 3 months of systemic glucocorticoid treatment, the levels of IL-1β, IFN-γ, IL-2, IL-17, and CXCL10 in responders were significantly decreased and nearly restored to normal levels. The IL-10 level was also increased in response to treatment. In contrast, the non-responder group had persistently high IL-6, IL-17, IL-8, and CXCL10 levels, and negligible changes in TNF-α, IL-1β, IFN-γ, IL-2, and IL-10.
CONCLUSIONS
Our study indicated that the levels of inflammatory cytokines were significantly ameliorated in the glucocorticoid responder group. Altered cell-mediated immunity may contribute to the resistance in vitiligo. The cytokines such as TNF-α, IL-1β, IFN-γ and IL-2 could serve as therapeutic targets for managing glucocorticoid-resistant vitiligo.

Journal of Multidisciplinary Healthcare 2024This study aimed to investigate the maintenance effect of two puncture methods using non-coring needles in children with totally implantable venous access device (TIVAD).
PURPOSE
This study aimed to investigate the maintenance effect of two puncture methods using non-coring needles in children with totally implantable venous access device (TIVAD).
METHODS
The 110 children who received TIVAD implantation for short bowel syndrome and solid tumors in our department from 2021.12 to 2022.12 were selected as the study subjects. Blinded method was used and divided into experimental group and control group according to random number table The experimental group underwent painless surround puncture method to place the needles and compound lidocaine ointment for topical anesthesia, while the control group underwent traditional puncture method to complete this operation. The effects of the two puncture methods on pain, catheter seal fluid volume, and catheter occlusion rate were evaluated using the Facial Pain Scale Revised, Behavioral Assessment Scale, and in vitro digital subtraction angiography test.
RESULTS
In the control group, the degree of puncture pain was mild in 5 patients, moderate in 19 patients, and severe in 28 patients; the amount of catheter sealing solution was 9.32 ± 1.32 mL, and the catheter occlusion rate was 25.00%. In the experimental group, the degree of puncture pain was mild in 16 patients, moderate in 22 patients, and severe in 16 patients; the amount of sealing solution was 7.66 ± 1.08 mL, and the blocking rate was 9.26%. The total pain score in the experimental group was lower than that in the control group (5.23±6.17 VS 7.89±2.38). The difference between the two groups had statistical significance < 0.05).
CONCLUSION
The use of the painless surround puncture method can effectively reduce the pain experienced by children during puncture, decrease the volume of catheter sealing fluid, reduce the rate of catheter blockage, provide a valuable basis for enhancing the maintenance effect of TIVAD in clinical practice for children.

BACKGROUND
is an aromatic desert plant used in Saudi folk medicine to treat skin infections. It is widely found in Middle Eastern countries.
METHODS
A methanolic extract of the plant was prepared, and its phytoconstituents were determined using LC-MS. and antibacterial and antibiofilm activities of the methanolic extract were evaluated against multidrug-resistant bacteria. The cytotoxic effect was assessed using HaCaT cell lines . Diabetic mice were used to study the antibiofilm and wound healing activity using the excision wound method.
RESULTS
More than 50 phytoconstituents were found in the extract after LC-MS analysis. The extract exhibited antibacterial activity against both the tested pathogens. The extract was free of irritant effects on mice skin, and no cytotoxicity was observed on HaCaT cells with an IC value of 1381 µg/ml. The ointment formulation of the extract increased the healing of diabetic wounds. The microbial load of both pathogens in the wounded tissue was also reduced after the treatment. The extract was more effective against methicillin-resistant (MRSA) than MDR- in both and experiments. Further, skin regeneration was also observed in histological studies.
CONCLUSIONS
The results showed that methanol extract supports wound healing in infected wounds in diabetic mice through antibacterial, antibiofilm, and wound healing activities.
