Retrospective Study of the Use of a Fractional Radio Frequency Ablative Device in the Treatment of Acne Vulgaris and Related Acne Scars  [PDF]
Judith Hellman
Journal of Cosmetics, Dermatological Sciences and Applications (JCDSA) , 2015, DOI: 10.4236/jcdsa.2015.54038
Abstract: Background: Acne vulgaris (AV) is a common disease that often results in disfiguring facial scarring that carries into adulthood. Here we report our experience with fractional radiofrequency (FRF) device in treatment of patients with acne and acne related scarring. Materials & Methods: We retrospectively reviewed the charts of all patients with acne scarring who completed a four treatment regimen in our clinic. Results: We identified eight patients who completed four treatments with median age of 20.5 years (range 17 - 41). All patients demonstrated significant improvement of acne lesions and acne scarring. Skin biopsies demonstrated reduction of scar depth and increased new collagen production, and repopulation of the scar tissue by elastic fibers and adnexal structures after the fourth treatment. Conclusion: FRF emerges as a safe and effective treatment modality for AV and acne related scars. Further randomized controlled studies are required to fully evaluate the magnitude of this positive effect and more basic science studies are needed in order to better characterize its mechanism of action on acne lesions.
Long Term Follow-Up Results of a Fractional Radio Frequency Ablative Treatment of Acne Vulgaris and Related Acne Scars  [PDF]
Judith Hellman
Journal of Cosmetics, Dermatological Sciences and Applications (JCDSA) , 2016, DOI: 10.4236/jcdsa.2016.63013
Abstract: Introduction: Acne vulgaris and acne scarring are prevalent conditions that can have a negative effect on a patient’s quality of life. Fractional radiofrequency technologies have been shown to be clinically safe and effective in managing acne scars through dermal remodeling without causing direct damage to the epidermis. In a recently published study, we presented our clinical and histological results in the treatment of patients with active acne and acne related scarring using a Fractional RF (FRF) device. In the current article we demonstrate long term follow-up results, up to two years post last fractional treatment. Methods: Four out of the eight patients who completed a four treatment regimen were invited for long term follow-up visit to document treatment results. In some cases, touch-up treatments were conducted to optimize clinical results. Results: Patients demonstrated significant improvement of acne lesions, acne scarring, pores and skin texture. Long term photos demonstrated that clinical improvement progressed with time. Conclusion: The current study further supports the previous findings that FRF is a safe and effective treatment modality for active acne and acne related scars. Treatment protocol can be customized according to patient needs and clinical results last for long term.
Retrospective Analysis of Outcomes with a Unique IPL System  [PDF]
Judith Hellman
Journal of Cosmetics, Dermatological Sciences and Applications (JCDSA) , 2021, DOI: 10.4236/jcdsa.2021.112012
Abstract: Introduction: Intense Pulsed Light (IPL) technology is well accepted in the medical aesthetic field for the treatment of various skin lesions, including pigmented and vascular lesions. The light penetrates into the skin and is selectively absorbed by lesion chromophore. Absorbed energy is converted into heat, coagulating the lesion, which naturally fades following the treatment. The current article presents a retrospective efficacy evaluation of an IPL device with high peak power. Methods: Representative treatment results were collected from several clinics based on photographs taken at baseline and after treatments. Photos were evaluated and analyzed for aesthetic improvement of the various skin conditions in different facial and body areas. Results: Analysis included cases of pigmented and vascular lesions, textural lesions, and more specific conditions such as melasma and rosacea. The two evaluators’ scoring demonstrated improvement in all cases according to the Global Aesthetic Improvement Scale (GAIS) scale. Conclusion: The vast experience gathered from the market in treating various skin lesions supports the safety and efficacy of the investigated IPL device. The device’s particular specifications contribute to the successful results and ease of treatment for the practitioner and the patient.
The Post-Modern Mind. A Reconsideration of John Ashbery’s “Self-Portrait in a Convex Mirror” (1975) from the Viewpoint of an Interdisciplinary History of Ideas  [PDF]
Roland Benedikter, Judith Hilber
Open Journal of Philosophy (OJPP) , 2012, DOI: 10.4236/ojpp.2012.21010
Abstract: This paper gives a short description of basic features of the dominating mindset in the Western world between the 1970s and today, often called “post-modern”, through a re-reading of John Ashbery’s poem “Self-Portrait in a Convex Mirror” (1975). In doing so, it applies the viewpoint of an interdisciplinary history of ideas. Since collective mindsets have become the most important contextual political factors, the implications are multiple.
Gender Differences and Leadership Styles in a Non Secular Setting  [PDF]
Judith Corbett Carter
Open Journal of Leadership (OJL) , 2012, DOI: 10.4236/ojl.2012.11001
Abstract: Women are increasingly taking on the role of religious leaders despite some institutional barriers. Do ef- fective female clergy lead differently than effective male clergy? The focus of this study was to examine gender differences in the context of non secular leadership. The Multifactor Leadership Questionnaire (MLQ) styles and NEO-Five Factor Inventory (FFI) was used to measure leadership and personal charac- teristics of female and male pastors. Limited findings indicate that female pastors were higher in Open- ness and Charisma than male pastors.
“I’ve Got the Pilot”: An Interpretation of Flight, a Film by John Gatins, Writer, and Robert Zemeckis, Director  [PDF]
Judith Ferster, Paul Weiser
Advances in Literary Study (ALS) , 2014, DOI: 10.4236/als.2014.23013
Abstract:

Robert Zemeckis’s recent film Flight, about a talented but flawed commercial airline pilot (played by Denzel Washington) is discussed on both the realistic and allegorical levels, showing the relationship between the contemporary plot and the fifteenth-century morality play, The Summoning of Everyman. Evidence for and against the different kinds of interpretation is identified and discussed. The film forces the main character to make a series of progressively more difficult and significant ethical decisions about drugs, alcohol, friends (true and false), lovers, and personal atonement that challenge him. The audience must make an interpretive decision between the possible levels of meaning.

Teachers Creating Effective Learning Experiences for Indigenous Learners  [PDF]
Lindsey Conner, Judith Bennetts
Creative Education (CE) , 2018, DOI: 10.4236/ce.2018.96074
Abstract: “Recently professional learning and development has turned a corner. Teachers as leaders of learning have realized that they can be agents of change within their classrooms by focusing on quite specific teaching changes to improve outcomes for their learners” (Conner, 2015: p. 7). This paper provides examples of how teachers were challenged to link changes in their practice to include good principles of indigenous pedagogies (through participating in cycles of teaching and inquiry), to changes in students’ outcomes, which has rarely been reported previously. Vignettes of changes teachers made to their teaching were gathered as they responded to reflections and support from mentors and used student achievement data as tools for inquiry. Teachers were provoked to be more aware of the importance of evidence-informed critical reflection on pedagogical development that was appropriate for indigenous students. We provide an overall analysis and vignette examples to illustrate the emerging themes which were: the development of positive professional relationships (mentor-teacher, teacher-teacher and teacher-student), developing pedagogical knowledge that was appropriate for indigenous students that was also informed by seeking student and whānau (family) voice or feedback to inform changes to teaching.
Novel Histological Evidence of Collagen and Elastin Regeneration in Fractional RF-Treated Acne Scars  [PDF]
Judith Hellman, Jonathan Yao
Journal of Cosmetics, Dermatological Sciences and Applications (JCDSA) , 2019, DOI: 10.4236/jcdsa.2019.92013
Abstract: Introduction: Fractional radiofrequency (RF) technology has been shown to be a gold standard therapy for acne scars. We have previously published clinical and histological results from the treatment of 8 patients with active acne and acne related scarring using a fractional RF device. Evidence of safety and efficacy was demonstrated, including long term follow-up clinical results from 4 patients, up to two years post last fractional treatment. In the current article we present histology evidence of acne scar skin renewal 3.5 years post treatment. Methods: Skin biopsies from acne scars in a concealed facial area were taken before, after four treatments and at 3.5 years after the last fractional treatment. Biopsies were examined with standard hematoxylin and eosin (H&E) stain, as well as Verhoeff’s Van Gieson (VVG) and Shikata stains for elastic fibers. Results: Histological findings demonstrate regeneration of elastic fibers and reduction of the dermal fibrosis. Scar depth of Patient #2 was reduced by 80% in the corresponding follow-up period. Conclusion: The long-term histological results further support the previously published findings that fractional RF is a safe and effective treatment for acne related scars.
Restoration of Forested Lands under Bauxite Mining with Emphasis on Guyana during the First Two Decades of the XXI Century: A Review  [PDF]
Susy Lewis, Judith Rosales
Journal of Geoscience and Environment Protection (GEP) , 2020, DOI: 10.4236/gep.2020.811003
Abstract: Mining poses a major environmental threat to tropical forest ecosystems, given its role in long-term forest degradation. Like Suriname, Guyana presents one of the less disturbed forested lands in South America. The local economy is improving, thanks to the development of mining which is primarily focused on gold, diamond, and bauxite. This, however, has resulted in long-term degradation of important forest ecosystems and the pollution of water bodies, and these have given rise to increasing concentrations of sediments. Taking into consideration the afore-mentioned, this review synthesizes, for the first time, literature which describes knowledge-based restoration practices in forested fragmented landscapes at different bauxite mining areas. The principal objective of this endeavor is to learn from case studies that have been carried out in the Neotropics especially in South America, with a view to applying best practices to the Guyana context. It has been found that mining presents a serious challenge for physical, chemical, and biological restoration. Comprehensive knowledge of the ecology of the landscape—structure and configuration, soil type, physical, chemical and biological properties, dispersal mode, and the identification and quantification/inventory of plant communities is critically important pinpointed for planning restoration programmes. The process of recovering some of the ecological functions of the pristine forest, through natural regeneration, is vital to supporting biodiversity in overburden dumps and to mitigating environmental impacts. One of these many functions, functional connectivity, can be enhanced to optimize the restoration of forest cover leading to an increase in local biodiversity. Bearing in mind the afore-stated, this review synthesizes passive and active restoration through reforestation with local and exotic species, ecological management of colonization, nucleation practices, and the use of Landscape Ecology models. These have been identified as the most appropriate to follow, given that a spatially driven design can provide much needed knowledge of the restoration/reclamation plan for Bauxite Mine Lands. Ecologically sound designs are a catalyst for devising mechanisms which can (help to) reduce environmental impacts. These designs can also help to boost the velocity at which ecological processes operate, in order to increase the resilience of ecosystems and the connectivity between forest patches and continuous pristine forests.

Psychology (PSYCH) , 2011, DOI: 10.4236/psych.2011.22019
Abstract: Deciding to initiate antiretroviral treatment (ART) for HIV involves a number of factors, including how one thinks about disease (illness appraisals) and how one thinks about treatment (medication appraisals). We conducted semi-structured interviews with 20 adults who were deciding whether to begin ART, in which participants were asked to relate their experience of testing positive, their experience with medications other than ART, and their thoughts about ART. Digital recordings were transcribed for team-based narrative analysis. In response to HIV+ diagnosis, participants described the following appraisals: 1) HIV is a threat to mortality; 2) nonacceptance of the HIV diagnosis; 3) HIV is associated with stigma and rejection; and, 4) the HIV diagnosis meant betrayal by a cared for other. Medication appraisals included: 1) negative feelings about medications in general, 2) taking HIV medication would create a personal crisis; 3) the benefits of taking HIV medication would not outweigh the costs; 4) doubts whether they could adhere, and 5) taking medications would be stigmatizing. Illness and medication appraisals may represent barriers to initiating and adhering to treatment and should be taken into account in helping clients to cope with their diagnosis and manage their healthcare.
