Skin-lightening patterns among female students: A cross-sectional study in Saudi Arabia.

BACKGROUND: Skin-lightening products (SLPs) are commonly used worldwide, and their improper use and overuse is becoming a burden on health care workers, including dermatologists. OBJECTIVE: This study aimed to determine the characteristics, determinants, preferences, and side effects of the use of SLPs among Saudi female students and their association with mental health. METHODS: A cross-sectional analytic study, using a self-administered prevalidated questionnaire, was conducted among female students in the Aljouf region of Saudi Arabia. We used the consecutive nonprobability sampling technique to recruit participants. The questionnaire contained demographic data, two questions about knowledge of SLPs, eight questions regarding perceptions of fair skin, and three proxy scales for mental health (depression, posttraumatic stress disorder, and Internet addiction). RESULTS: The mean age of the participants (± standard deviation) was 29 ± 9.6 years. Of the 760 responders, 427 (56.2%) used SLPs; all were women with relatively light skin (types III-V). There was a unanimous positive perception of lighter skin tone among women. The participants used skin-lighteners for cosmetic and medical conditions (67.2% and 17.5%, respectively). The practice was significantly associated with poor mental health status, poor level of knowledge, and lower sociodemographic status (p < .05). CONCLUSIONS: The use of SLPs is highly prevalent among Saudi female students. Users believe that fairer skin is associated with beauty and social advantage. Female students with a lower economic status and poor mental health are more prone to overuse SLPs. A need exists for targeted public health campaigns to raise public awareness about uncontrolled skin lightener usage.

Relationship between tooth value and skin color in patients visiting Royal Medical Services clinics of Jordan.

BACKGROUND: Facial and dental aesthetics are becoming of great concern for patients, especially for the younger generation. Tooth color matching and selection is considered a vital element in order to create an attractive beautiful smile. The importance of tooth color matching is to adjust tooth colors to obtain a good match with adjacent teeth and the skin. This is considered a challenge especially if adjacent teeth were lost or records of patients' teeth color were not available. OBJECTIVE: The aim of this study was to determine the relationship between skin complexion and tooth value in a Jordanian population. METHODS: A cross-sectional study of 520 individuals who were randomly selected and belonging to different age groups, ranging from 15-65 years, with equal sex distribution. These patients visited the dental clinics at different Jordanian military hospitals. The study was carried out over a period of one year from 2015 to 2016. The randomly selected sample was examined by one researcher. Shade of the middle third of the labial surface of central incisor was determined visually using VITA tooth guide, 3D-MASTER shade guide. Tooth shades were divided into two categories according to their value. The skin complexion was identified using Fitzpatrick skin type test, and was categorized into two categories (fair and dark). Data were statistically analyzed using Epi Info version 6. RESULTS: A statistically significant tooth shade value difference was discovered among subjects of different skin color (p<0.0001). Individuals with dark skin tend to have lighter teeth, while individuals with light skin tend to have darker teeth. Out of the 304 participants that were with dark complexion 274 (90%) have light teeth, and only 30 (10%) were with dark teeth. Out of the 216 participants with light complexion 172 (80%) have dark teeth and only 44 (20%) have light teeth. CONCLUSION: Within the limitation of this study, there was an inverse relation between skin complexion and tooth value among a Jordanian population. Thus, considering the skin complexion when choosing tooth shades is helpful in achieving a pleasing good-looking smile, yet further investigations in this field must be carried out.

The significance of age group, gender and skin complexion in relation to the clinical distribution of developmental oral mucosal alterations in 5-13 year-old children.

INTRODUCTION: To describe the relationship and impact of age group, gender and skin complexion on the prevalence and clinical distribution of oral mucosal alterations of developmental origin (OMA-DO) among school children aged 5-13 years. METHODS: A randomized representative national survey of Jordanian school children including all Country geographic areas was performed. Cut-off age that significantly correlated with presence and distribution of OMA-DO was identified (ROC curve). Skin complexion was classified into light/fair, intermediate/tan, dark/brown based on skin complexion index. Chi square test with P value≤0.05 was used for significance of correlations. RESULTS: Two thousand two hundred and fifty one children were clinically examined. The average age that significantly correlated with prevalence and distribution of OMA-DO was 9.9 years. Female gender was significantly correlated with four OMA-DO: leukoedema (L), linea Alba (LA), Fordyce's granules (FG), commissural lip pits (CLP) and wider distribution of racial pigmentations (RP) (P<0.05, χ2 test). Older age group (9.9-13 years) was significantly correlated with 7 OMA-DO: L, LA, FG, frenal tag, CLP, mandibular and maxillary tori (MT) as well as wider clinical distribution of RP, FG, L (P<0.05 χ2 test). Dark skin complexion significantly correlated with 5 OMA-DO: L, LA, FG, RP, MT and wider clinical distribution of RP (P<0.02, χ2 test). CONCLUSIONS: Increased prevalence and wider clinical distribution of OMA-DO are significantly associated with older age group of 9.9-13 years, female gender, and dark skin complexion. Oral health care provides are encouraged to be familiar with these correlations. This knowledge is expected to improve OMA-DO diagnosis and clinical management. Continuous education programs in this field are recommended.

Clinical Anaemia Detection in Children of Varied Skin Complexion: A Community-based Study in Southeast, Nigeria.

BACKGROUND: Clinicians rely on clinical detection of pallor to diagnose anaemia. This makes it important to evaluate the effect of different skin complexions on the accuracy of the pallor in diagnosing anaemia in children. METHODS: Clinicians conducted blind-independent physical examination, and their reports were compared with HemoCue 301 haemoglobin estimated with. The sensitivity and specificity were calculated. RESULTS: A total of 573 children were reviewed by 27 healthcare workers. The prevalence of anaemia was high. The highest prevalence was among children between the age of 4 and 12 months (urban 63.4% and rural 69.2%). Anaemia was detected better among dark-skinned children. Conjunctivae and palm pallor had the highest sensitivity (78.6% and 69.2%, respectively). DISCUSSION: Clinical pallor is a good screening assessment for anaemia but not diagnostic. Its sensitivity and specificity vary among different sites and skin complexions. Thus combining findings at any of the sites can improve detection of anaemia in children.

Changes of skin complexion after ultraviolet A (UVA) and ultraviolet B (UVB) exposure / 中华皮肤科杂志

Objective To observe the alteration of skin complexion after UVA and UVB exposure.Methods The back skin of ten females with skin type Ⅲ was subjected to single exposure to solar-simulated UVA of double minimal persistent pigment darkening (MPPD) or UVB of double minimal erythema dose (MED). Skin reflectance was assessed with clinical grading, spectcolometer and Mexameter MX 18 before irra-diation, 6 hours, 1, 7 and 14 days after the irradiation. Results After UVB irradiation, a~* value and erythema index (EI) abruptly increased at 6 hours and peaked on day 2; L~* value sharply declined on day 1; ITA° markedly decreased on day 7; melanin index (MI) declined within the first 2 days, but notably increased on day 7. After UVA irradiation, a~* and El value experienced no apparent changes; L~* value obviously declined at 6 hours; ITA° reached its lowest value on day 14; MI increased only on day 1. Conclusions There is a significant difference in the kinetics and extent of skin complexion changes after UVA and UVB irradiation. EI and a~* value are sensitive and accurate indices for evaluating sunburn, and MI and ITA ° for analyzing tanning.
