Abstract

BackgroundMalignant melanoma (MM) is a neoplasia derived from melanocytes. This is the most aggressive cancer ofskin. Even small tumors may have a tendency to metastasize and thus lead to a relatively unfavorableprognosis. Malignant melanoma depth of invasion based on Clark level is one of the important prognosticfactors to determine survival rate of MM patient. Determination of invasion based on this Clark level issubjective, more objective checks such as Ki-67 and E-Cadherin are required. This examination isexpected to see the risk of metastasis in MM. Cell proliferation is the main key for tumor progression and itcan be measured with Ki-67 expression. E-cadherin is one of transmembrane protein that plays importantrole in metastasis. The purpose of this study is to determine correlation between Ki-67 and E-Cadherinexpression with depth of invasion of malignant melanoma based on Clark level.MethodsThis is cross sectional study in Padang and Jakarta, with 42 cases of malignant melanoma which havebeen diagnosed in Pathology Anatomic Laboratory in West Sumatera. Samples were obtained fromparaffin block of or tissue from surgery and have been reviewed depth of invasion based on the Clark level.These samples were divided into I-V Clark level group. Ki-67 expression of cells nuclei and expression ofE-Cadherin of cells membrane were analyzed using immunohistochemistry assay. One Way Annovabivariate statistical analysis were used and value p<0.05 were considered significant.ResultsPositive Ki-67 expression were found in 42 cases, 6 samples with II Clark level, 8 samples with III Clarklevel, 19 samples with IV Clark level, 9 samples with V Clark level. Malignant melanomas were mostlyfound in male 60-79 age group and depth of invasion in IV Clark level. Positive E-Cadherin expression in IIClark level. There was significant correlation between Ki-67 and E-Cadherin

Abstract

Post-acne scars are a condition of skin layer damage due to the healing process of acne vulgaris, causing the skin to appear depressed. This condition disrupts facial aesthetics and may become permanent, thereby affecting the patient’s psychological condition and quality of life. This study aimed to determine the relationship between the severity of post-acne scars and the quality of life among medical students of FK UNAND, Padang, Indonesia. This study was an analytic observational study with a cross-sectional design conducted from June to December 2023. The population consisted of medical students of FK UNAND batch 2020–2022 who had acne scars. The total sample was 88 respondents selected using consecutive sampling. Data were collected using the Facial Acne Scar Quality of Life (FASQOL) questionnaire and Dysmorphic Concern Questionnaire (DCQ). Statistical analysis was performed using One-Way ANOVA and Fisher’s Exact Test. The results showed that most respondents were female and aged 21 years. The majority experienced mild acne scars (46.6%). The mean FASQOL score was 14.11. Most respondents felt disturbed by the presence of acne scars on their face. The DCQ results showed that 88.6% of respondents had no dysmorphic disorder features. There was no significant relationship between acne scar severity and quality of life (p=0.938) nor dysmorphic disorder (p=0.241). The study concluded that there was no relationship between the severity of post-acne scars and the quality of life among medical students of FK UNAND, Padang, Indonesia

Abstract

ABSTRACT Indonesia is one of the countries with high exposure to sunlight, and most of its population works outdoors, making skin protection necessary. While sunlight provides benefits, it also has harmful effects on the skin if exposed excessively. Ultraviolet rays, UVB and UVA, work synergistically to damage the skin, thus requiring prevention or protection to reduce the negative impacts of radiation. Excessive sun exposure is the main exogenous mediator of skin damage. The negative effects of sun exposure on the skin lead to various skin problems such as darkening, wrinkles, dullness, and the appearance of dark brown spots, and it can even cause skin cancer. Therefore, using sunscreen is crucial as it can prevent UV rays from penetrating the skin. This study uses a literature review design, where relevant scientific articles are analyzed to explore the potential of natural ingredients as sunscreen agents. A total of 9 articles were collected from various databases, including PubMed, ScienceDirect, and Google Scholar, using specific keywords related to UV protection, natural sunscreen, and bioactive compounds in plants. The selection of articles was based on inclusion and exclusion criteria, ensuring that only recent and relevant studies were considered. Natural ingredients have not yet been widely utilized in the sunscreen industry. Plants contain substances that can be extracted and serve as a potential source of sunscreen due to their photoprotective properties. This provides insight into the ability of plants to protect the skin through the compounds they contain, such as bioactive compounds like phenolic substances and antioxidants.
