Cocos nucifera and glycerine afterwork moisturizers for secondary prevention of hand dermatitis among fabric worker: a randomized, double-blind, cross over trial.

The use of skin barrier-enhancing topical medication is a favorable approach for the treatment of occupational hand dermatitis (OHD). Cocos nucifera or coconut oil is one of the best sources of lipid enriched with laurate acid, and glycerin is a well-known humectant that improves skin hydration. This study is aimed is to evaluate the effectiveness of C. nucifera and glycerin for secondary prevention of OHD among batik (Indonesian traditional fabric) workers. In a randomized, double-blind, crossover trial, the effect of glycerine-C. nucifera cream versus glycerin-only was considered with multiple afterwork applications of moisturizer over a 2-week period on batik workers with OHD. Assessment of trans-epidermal water loss (TEWL), skin capacitance, and a clinical assessment using the Hand Eczema Severity Index (HECSI) were carried out at day 0 and 14. The results show thirty-two batik dyeing and/or rinsing workers were enrolled in the study with mild to moderate OHD. Clinical improvement was demonstrated by 20% decrease in HECSI and TEWL, and 20% increase in skin capacitance. Both moisturizers were equally effective for the secondary prevention of OHD. As a conclusion, glycerine-C. nucifera and glycerin-only cream are equally effective for secondary prevention for OHD among batik worker to reduce the prevalence of hand dermatitis.

The Comparison between Microneedling and Fractional CO2 Laser for Amniotic Membrane Stem Cell-Conditioned Medium and Vitamin C in Photoaging Treatment.

Context: Photoaging correlates with ultraviolet radiation (UVR). In addition to direct and indirect DNA damage, UVR leads to a breakdown of collagen, resulting in enlarged pores, visible wrinkles, also uneven skin tones and pigmentations. Amniotic membrane stem cell (AMSC) can be a useful modality in cell regeneration. Vitamin C has been known as an agent of depigmentation, antioxidants, and collagen synthesis. A topical combination of amniotic membrane stem cell-conditioned medium (AMSC-CM) and vitamin C is expected to improve photoaging. Fractional CO2 laser and microneedling served as transdermal drug delivery. Aims: To compare between microneedling and fractional CO2 laser for the administration of AMSC-CM and vitamin C in photoaging treatment. Methods and Material: Sixty Indonesian women with photoaged skins participated in this experimental analytic, controlled, matching research and were divided into two groups. Thirty women received fractional CO2 laser, and others received microneedling. All participants received a topical combination of AMSC-CM and vitamin C. Three treatment sessions were repeated at a four-week interval for fractional CO2 laser and a two-week interval for microneedling. We evaluated the progression and side effects using a skin analyzer on weeks 0, 4, and 8 for the microneedling group and for the fractional CO2 laser group on weeks 0, 4, and 12. Results: Assessment of wrinkles, UV spots, skin tone, and pore revealed a statistically significant effect of a topical combination of AMSC-CM and vitamin C after fractional CO2 laser (p < 0.05). Conclusions: Combination of AMSC-CM and vitamin c using fractional CO2 laser can improve photoaging and is better compared to microneedling.

The optimum oxygen level in hypoxic culture conditions of ligament derived stem cells: experimental research.

The hypoxic condition is a physiological norm for various stem cells. The natural microenvironment contains lower oxygen pressures. Recent studies reported significant increases in the cultured cells' proliferation in the presence of a low oxygen pressure. Objective: This study aimed to investigate the optimum oxygen level for rabbit cruciate ligament fibroblast cells culture and Ligament Derived Conditioned Medium/LD-CM (Secretome) preparation in vitro. Materials and methods: Fibroblasts were isolated from the cruciate ligament of the rabbit's knee. Cultured of rabbit cruciate ligament Fibroblast Cells (fifth passage) were assigned to the slight (5% O2), middle (3% O2), and severe hypoxia (1% O2) groups and the normoxia (21% O2) group. Measurement of growth factors: TGF-ß1, PDGF, FGF, and VEGF in LD-CM (Secretome) used an enzyme-linked immunosorbent assay. Results: The highest number of cultured cells were in the 5% O2 group compared to the normoxia, 1 and 3% groups. The hypoxia 5% group also had increased productions of PDGF, FGF, and VEGF proteins in LD-CM (secretome) compared to the 1, 3%, and normoxia groups. TGF-ß1 production was slightly higher in the 3 group than the 5% group. Conclusion: The hypoxic precondition of 5% oxygen was the optimum condition for ligament culture and ligament derived conditioned medium (secretome) preparation in vitro.

Resveratrol promotes secretion of wound healing related growth factors of mesenchymal stem cells originated from adult and fetal tissues.

Non-healing wounds have demonstrated aberrant regulation of several growth factors, thus using exogenous growth factors and cytokines in the clinical setting may improve the outcomes of non-healing wounds. Mesenchymal stem cells (MSCs) are the source of growth factors that show beneficial effect in promoting impaired wound healing. Certain culture condition should be developed to stimulate growth factor secretion from stem cell. Resveratrol, a small molecule found to increase MSCs therapeutic effectiveness. This study aims to investigate the effect of RV on secretion of wound healing related growth factors. We isolated and characterised MSCs from wharton's jelly (WJ), amniotic membrane (AM), and adipose tissue. We treated MSCs with serum deprived medium (SDM) supplemented with RV at 0.1 µM, 0.5 µM, 0.8 µM concentration. Our study revealed that RV at 0.1 µM was more effective to increase cell proliferation rate. Resveratrol at 0.1 µM promoted EGF, HGF, PDGF, and TGF-ß1 secretion from MSCs. AD-MSCs showed the greatest response to RV stimulation in the term of cell proliferation and growth factors secretion. As conclusion, RV can facilitate cell proliferation and wound healing related growth factors secretion at dosage dependent manner.

Prevalence and characterisation of Staphylococcus aureus causing community-acquired skin and soft tissue infections on Java and Bali, Indonesia.

OBJECTIVES: To define the role of Staphylococcus aureus in community settings among patients with skin and soft tissue infections (SSTI) in Indonesia. METHODS: Staphylococcus aureus were cultured from anterior nares, throat and wounds of 567 ambulatory patients presenting with SSTI. The mecA gene and genes encoding Panton-Valentine leukocidin (PVL; lukF-PV and lukS-PV) and exfoliative toxin (ET; eta and etb) were determined by PCR. Clonal relatedness among methicillin-resistant S. aureus (MRSA) and PVL-positive S. aureus was analysed using multilocus variable-number tandem-repeat analysis (MLVA) typing, and multilocus sequence typing (MLST) for a subset of isolates. Staphylococcal cassette chromosome mec (SCCmec) was determined for all MRSA isolates. Moreover, determinants for S. aureus SSTI, and PVL/ET-positive vs PVL/ET-negative S. aureus were assessed. RESULTS: Staphylococcus aureus were isolated from SSTI wounds of 257 (45.3%) patients, eight (3.1%) of these were MRSA. Genes encoding PVL and ETs were detected in 21.8% and 17.5% of methicillin-susceptible S. aureus (MSSA), respectively. PVL-positive MRSA was not detected. Nasopharyngeal S. aureus carriage was an independent determinant for S. aureus SSTI (odds ratio [OR] 1.8). Primary skin infection (OR 5.4) and previous antibiotic therapy (OR 3.5) were associated with PVL-positive MSSA. Primary skin infection (OR 2.2) was the only factor associated with ET-positive MSSA. MLVA typing revealed two more prevalent MSSA clusters. One ST1-MRSA-SCCmec type IV isolate and a cluster of ST239-MRSA-SCCmec type III were found. CONCLUSIONS: Community-acquired SSTI in Indonesia was frequently caused by PVL-positive MSSA, and the hospital-associated ST239-MRSA may have spread from the hospital into the community.
