Dermatoscopic imaging of skin lesions by high school students: a cross-sectional pilot study.

ABSTRACT: BACKGROUND:The ability of novices to perform imaging of skin lesions is not well studied. OBJECTIVES:To determine the ability of 12th grade high school students without formal training to take clinical and dermatoscopic images of skin lesions on patient-actors. PATIENTS/METHODS:Nineteen participants were divided into 11 gender-specific groups of 1-2 students. Groups were provided written instructions and assessed in their ability to (a) identify 8 pre-specified skin lesions, (b) take overview clinical images, and (c) take contact, polarized dermatoscopic images. Groups captured the same images twice using two different cameras [Nikon TM 1 J1 / VEOS HD1 and a VEOS DS3 (Canfield Scientific, Inc.)]. The sequence of camera use was determined using block randomization. If students made visibly poor skin contact during dermatoscopic imaging using their first camera, study investigators provided verbal instructions to place the second camera directly onto the skin. Students completed anonymous surveys before and after the imaging activity. RESULTS:Students were proficient at identifying the correct pre-specified skin lesions (86/88, 98%), capturing sufficient quality overview clinical images of the back and legs (41/42, 98%), and taking dermatoscopic images of the entire skin lesion (174/176, 99%). Regarding dermatoscopic image quality, 116 of 175 (66%) images were in focus. Out of focus images were attributed to poor skin contact. Groups that received feedback (n=4) were able to obtain a significantly higher proportion of in focus dermatoscopic images using their second camera compared to their first camera (16% to 72%, P<0.001). CONCLUSIONS:We identified several barriers that exist for participant-acquired dermatoscopic imaging. Instructions emphasizing the importance of skin contact are useful. Our results may help guide future patient-acquired teledermatoscopy efforts.

Project description:ObjectivesDepression is one of the most widely reported mental health issues that affect adolescents globally. However, there is a dearth of data on its prevalence and associated factors among senior high school students in Ghana, since previous studies have focused more on adult populations. This can hinder policies needed to champion mental health and mental health care in senior high schools. Hence, this study sought to assess the prevalence of depression and associated factors among senior high school students in Ghana.MethodsAn analytical cross-sectional study involving 289 students at the Manya Krobo Senior High School was conducted from December 2022 to February 2023. The students were selected using a two-stage random sampling method. A questionnaire was used to collect data on sociodemographics and individual characteristics. The primary outcome was depression, and this was assessed using the Patient Health Questionnaire-9. Summary statistics were presented as means, frequencies, and percentages. Multivariate logistic regression was used to identify factors associated with depression and odds ratios presented with 95% confidence intervals. Statistical significance was considered at p-value < 0.05.ResultsThe mean age of the students was 16.6 (±1.2) with a range of 14-20 years. Over a quarter (26.3%) of the students reported financial difficulties. The prevalence of depression among the students was 68.9%. The factors associated with depression in this study were female sex (adjusted odds ratio: 1.74, 95% confidence interval: 1.01-2.97), age (adjusted odds ratio: 1.41, 95% confidence interval: 1.10-1.81), history of chronic health condition (adjusted odds ratio: 3.74, 95% confidence interval: 1.36-10.25), and financial difficulties (adjusted odds ratio: 2.31, 95% confidence interval: 1.15-4.63).ConclusionThis study shows that depression is rife among students at the Manya Krobo Senior High School, Manya Krobo District, Ghana. These findings call for pragmatic interventions such as strengthening counseling units and professional mental health services to ameliorate the impact of depression on the lives of students.

Project description:BackgroundHealth outcomes of electromagnetic fields (EMF) from mobile phones and their base stations are of concern. Conducting multidisciplinary research, targeting children and exploring dose-response are recommended. Our objectives were to describe the mobile phone usage characteristics of high school students and to explore the association between mobile phone usage characteristics, high school EMF levels and self-reported symptoms.MethodsThis cross-sectional study's data were collected by a survey questionnaire and by measuring school EMF levels between November 2009 and April 2011. A sample size of 2530 was calculated from a total of 20,493 students in 26 high schools and 2150 (85.0%) were included in the analysis. The frequencies of 23 symptoms were questioned and analysed according to 16 different aspects of mobile phone use and school EMF levels, exploring also dose-response. School EMF levels were measured with Aaronia Spectran HF-4060 device. Chi square and trend tests were used for univariate and logistic regression was used for multivariate analyses.ResultsAmong participants, 2021 (94.0%) were using mobile phones and 129 (6.0%) were not. Among users, 49.4% were speaking <10 min and 52.2% were sending/receiving 75 or more messages per day. Headache, fatigue and sleep disturbances were observed respectively 1.90 (95% CI 1.30-2.77), 1.78 (1.21-2.63) and 1.53 (1.05-2.21) times more among mobile phone users. Dose-response relationships were observed especially for the number of calls per day, total duration of calls per day, total number of text messages per day, position and status of mobile phone at night and making calls while charging as exposures and headache, concentration difficulties, fatigue and sleep disturbances as general symptoms and warming of the ear and flushing as local symptoms.ConclusionsWe found an association between mobile phone use and especially headache, concentration difficulties, fatigue, sleep disturbances and warming of the ear showing also dose-response. We have found limited associations between vicinity to base stations and some general symptoms; however, we did not find any association with school EMF levels. Decreasing the numbers of calls and messages, decreasing the duration of calls, using earphones, keeping the phone away from the head and body and similar precautions might decrease the frequencies or prevalence of the symptoms.
