OCLC Number/Unique Identifier: 7317627578

Regenerative medicine is a modern approach of dermatological treatment, using Epidermal Cells of the interfollicular epidermis (ESCs) for their effect in skin regeneration in chronic ulcers and burns, melanoma, vitiligo, junctional epidermolysis bullosa. Intraepidermal injections of autologous epidermal cell suspension can be a new and very promising treatment for many other cutaneous disorders as non-scarring alopecia (Alopecia Areata, Androgenic Alopecia) or scarring alopecia (Lichern Plano Pilaris alopecia, Discoid Lupus Erithematosus alopecia), anti-aging therapies. The intraepidermal injection of an autologous epidermal cell suspension is a simple, fast and safe surgical procedure: a small, thin portion of the epidermis of the patient undergoes a treatment where a suspension with all the cells collected from the epidermis and cultured for 7 days is injected into the skin. Our preliminary study shows that a suspension contains a significant number of viable cells that survive at day 7 in culture. Our research is ongoing and is focusing on the typing of the different cells in the suspension and evaluation of the presence and the nature of stem cells.

Effectiveness of ethinyl oestradiol /cyproterone acetate and ethinyl oestradiol/ desogestrel with or without low-dose metformin on perceived health-related quality of life in hirsute women with polycystic ovary disease: A randomised, double-blind, placebo-controlled study

Published on: 6th August, 2019

Background: Polycystic ovary disease (PCOD) is an endocrine disorder. It leads to menstrual disturbances, infertility, obesity and dermatological manifestations such as hirsutism and acne which leads to impaired health-related quality of life (QOL). Aims: To evaluate the perceived health related QOL in patients with PCOD treated with ethinyl oestradiol (35µg)/cyproterone acetate (2 mg) (EE/CPA) and ethinyl oestradiol (20 µg)/ desogestrel (0.15mg) (EE/DES) alone and in combination with low-dose metformin. Methods: A total of 117 patients with PCOD diagnosed according to Rotterdam Consensus Criteria 2003 with a hirsutism score of 8 or more according to modified Ferriman-Gallway Score (mFGS) were randomised to receive one of four drug combinations (arm A – EE/CPA, arm B- EE/DES, arm C- EE/CPA plus metformin, arm D- EE/DES plus metformin). The outcomes assessed were body mass index (BMI), hirsutism (using mFGS) and health-related QOL (Polycystic Ovary Syndrome Health- Related quality of life Questionnaire (PCOSQ) and a Visual Analog Scale (VAS) score) at baseline and 12 months after treatment. Results: PCOSQ score in relation to the hirsutism, emotions, menstruation, obesity, infertility and VAS score in relation to hirsutism and obesity had improved at the end of 12 months (p< 0.001) in all treatment arms. There was no difference between treatment arms in all measured outcomes at baseline and at the end of 12 months. Conclusion: Treatment with EE/CPA and EE/DES is associated with an improvement in perceived QOL in patients with PCOD. The addition of low-dose metformin did not have a significant benefit.

Bee venom: a case of effectiveness on skin varicosities veins with review of its dermatological benefits

Published on: 21st May, 2020

OCLC Number/Unique Identifier: 8870468269

Bee venom is a very rich and varied biochemical complex, which explains the multitude of its physiological effects as well as its medical indications. In dermatology, apart from psoriasis, few studies have been conducted concerning its interest and effectiveness; however the preliminary results remain so promising and encouraging. We present a clinical case illustrating the efficacy of bee venom in cutaneous varicosities, with a review of the literature of its main dermatological indications.

Artemisia Naphta: A novel oil extract for sensitive and acne prone skin

Published on: 15th June, 2021

OCLC Number/Unique Identifier: 9124793207

Background: The plant Artemisia annua has been used in traditional Chinese medicine for many years. Rich in bioactive molecules, the A. annua plant is used to extract the anti-malaria compound artemisinin (< 1%), which results in most of the plant being unutilized. One byproduct of artemisinin extraction is artemisia naphtha (AN), which has yet to be studied extensively. Aims: Study the activity of a novel AN oil extract against microbes, pro-inflammatory cytokines, and dermatological endpoints that are key for eczema and acne pathogenesis to determine if an effective A. annua extract for these skin conditions can be developed. Methods: Gas chromatography-mass spectrometry was performed to determine the composition of AN oil. P. acnes, S. aureus, M. furfur, and C. albicans were cultured to determine minimal inhibitory concentration. in vitro studies utilizing keratinocytes and macrophages were treated with AN oil and gene expression measured by quantitative RT-PCR. A 13-subject clinical trial was performed with 1% AN oil Gel to assess its potential benefits for sensitive and acne prone skin. Results: AN oil upregulates filaggrin gene expression and possesses antimicrobial and anti-inflammatory activity inhibiting LPS, S. aureus and "Th2 induced" pro-inflammatory mediator release (IL-6, IL-8 and TSLP). Clinical assessment of 1% AN Gel shows it reduces acne blemishes and the appearance of redness. Conclusion: Previously an underutilized and unpurified byproduct, AN is now the source to develop the first topical AN oil for cosmetic use with an activity profile that suggests it is effective for those with sensitive and/or acne prone skin.

The dermatologic manifestations of COVID-19: a mini-review

Published on: 27th August, 2021

OCLC Number/Unique Identifier: 9244773760

Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), was identified in Wuhan, China, and caused coronavirus disease-19 (COVID-19), which is still a global pandemic. Dermatologic manifestations have increasingly been identified as significant extrapulmonary manifestations of COVID-19. The dermatologic manifestations associated with COVID-19 infection reported to date include maculopapular rash, vesicular lesions, urticaria-like lesions, and chilblain-like lesions. Knowledge of dermatologic manifestations of COVID-19 may be essential for early diagnosis and a better prognosis in COVID-19 patients. This review summarizes the current understanding of common COVID-19-associated dermatologic manifestations.

A Genetic study in assisted reproduction and the risk of congenital anomalies

Published on: 12th October, 2021

OCLC Number/Unique Identifier: 9305465911

In vitro fertilization is one of the most common and effective procedure for thousands of couples worldwide who want to have a child and are unable to do so for various reasons. Diverse studies show that couples who conceive naturally after one year of trying had newborns with an increased risk of prematurity and low birth weight, compared with couples who conceived before completing one year of trying. Children from assisted reproduction (AR), have a 30% increased risk of prematurity and low birth weight, compared with children from infertile fathers. Regarding the conflicting results the present study aimed to record the frequency of genetic, congenital anomalies in children and adolescents who had examined in the last decade to the Clinical Genetics Clinic of the National and Kapodistrian University of Athens whose mothers had undergone assisted reproduction. The research process was conducted at the "Aghia Sofia" Children's Hospital based in Athens. However, the cases that were studied came from all over Greece. Initially, the researcher recorded the cases that came to the clinic of Clinical Genetics and whose conception occurred after technical assisted reproduction. After telephone communication and the consent of the parents, a live appointment was scheduled. In this meeting-interview all the provisions of the investigation and the protocol were asked and some elements of the medical history of the cases were confirmed. The total sample included 230 children and adolescents. The resulting data were recorded on a printed form/questionnaire. Then, they were registered electronically in the program SPSS 25.0 (Statistical Package for Social Sciences) with a specific unit code for each case/patient, followed by the processing and statistical analysis of the data as well as the recording of the results. The gender of the participants was male for 118 participants (51.3%) and 112 females (48.7%). Mean and standard deviation (SD) of maternal, paternal (at the time of delivery) age was equal to 36.38 (5.94) and 39.94 (6.58) respectively. The observed abdormalities were 35.53% psychomotor retardation, 23.68% facial abnormalities, 23.68% spinal cord abnormalities, 21.05% morphological abnormalities, 20.61% short stature, 19.74% developmental disorders, 19.30% heart disease, 16.67% neurological diseases, 14.47% genetic syndromes, 11.40% genital abnormalities, 8.33% limb abnormalities, 7.46% dermatological abnormalities, 6.14% eye abnormalities, 6.14% hypothyroidism, 5.70% endocrine disorders, 5.26%otolaryngology abnormalities, 2.63% disease of kidney, intestine, 2.19% vascular malformations. Regarding the karyotype chromosome analysis by G-banding technique, from the 230 children in: 24 (10.43%) a pathological result was found, in 158 children (68.70%) it was found normal (46, XX or 46, XY by case) without other findings, while in 48 children (20.87%) the test was not performed for various reasons. Regarding the results of molecular analysis (DNA) from the 230 children, in 50 (21.74%) a pathological finding was found, in 56 children (24.35%) no abnormalities were found and in 124 children (53.91%) no molecular analysis was performed for various reasons. In conclusion, the sample of this descriptive study is characterized as uniform in terms of the method of assisted reproduction since 96.24% had followed the classic IVF. Full-term pregnancy was associated with the appearance of malignancy and head morphological abnormalities (64.6%), normal pregnancy was associated with genetic syndromes (18.2%) and facial abnormalities (11.1%). It is recommended the screening oocyte and sperm donors in order to help protect the safety and health of donors, recipients, and future offspring. The present study confirms the association of the presence of congenital anomalies after in vitro fertilization (IVF). However, the absolute risk of developing severe dysplasias after an IVF procedure is limited.
