CONDUCTIVE KERATOPLASTY: a RADIOFREQUENCY-BASED TECHNIQUE for the CORRECTION of HYPEROPIA by Marguerite B
CONDUCTIVE KERATOPLASTY: A RADIOFREQUENCY-BASED TECHNIQUE FOR THE CORRECTION OF HYPEROPIA BY Marguerite B. McDonald MD ABSTRACT Purpose: To evaluate the data on the safety, effectiveness, and stability of conductive keratoplasty (CK), a thermal, radiofrequency- based technique for treating 0.75 to 3.00 diopters (D) of spherical hyperopia. Methods: A prospective, consecutive series, multicenter clinical trial involving 400 hyperopic eyes was conducted by 19 surgeons at 12 centers. The treatment goal was emmetropia. Cohort follow-up was up to 2 years. Results: At 12 months postoperatively, data were available for 97.5% (354/363) of eyes for efficacy variables and 98% (391/400) of eyes for safety variables. A total of 54% of the CK eyes showed 20/20 or better uncorrected visual acuity, and 92% showed 20/40 or better at 12 months. The mean postoperative manifest refractive spherical equivalent was within 0.50 D in 61% and within 1.00 D in 88%. After CK, eyes were approximately 0.50 D myopic at month 1 and effectively emmetropic at 6 months. At 24 months, there was a 20% loss of initial effect. Safety results showed a 2-line loss of best-corrected visual acuity in 2% of the CK-treated eyes. The incidence of induced cylinder of 2.00 D or greater was below 1%. Conclusion: The CK technique corrects low to moderate hyperopia effectively and safely and with acceptable stability. It spares the visual axis, does not require the creation of a large flap, and is not associated with postoperative dry eye. CK has value as an alternative to hyperopic LASIK for patients with hyperopia. -
Soft Tissue Laser Dentistry and Oral Surgery Peter Vitruk, Phd
Soft Tissue Laser Dentistry and Oral Surgery Peter Vitruk, PhD Introduction The “sound scientific basis and proven efficacy in order to ensure public safety” is one of the main eligibility requirements of the ADA CERP Recognition Standards and Procedures [1]. The outdated Laser Dentistry Curriculum Guidelines [2] from early 1990s is in need of an upgrade with respect to several important laser-tissue interaction concepts such as Absorption Spectra and Hot Glass Tip. This position statement of The American Board of Laser Surgery (ABLS) on soft tissue dentistry and oral surgery is written and approved by the ABLS’s Board of Directors. It focuses on soft tissue ablation and coagulation science as it relates to both (1) photo-thermal laser-tissue interaction, and (2) thermo-mechanical interaction of the hot glass tip with the tissue. Laser Wavelengths and Soft Tissue Chromophores Currently, the lasers that are practically available to clinical dentistry operate in three regions of the electromagnetic spectrum: near-infrared (near-IR) around 1,000 nm, i.e. diode lasers at 808, 810, 940, 970, 980, and 1,064 nm and Nd:YAG laser at 1,064 nm; mid-infrared (mid-IR) around 3,000 nm, i.e. erbium lasers at 2,780 nm and 2,940 nm; and infrared (IR) around 10,000 nm, i.e. CO2 lasers at 9,300 and 10,600 nm. The primary chromophores for ablation and coagulation of oral soft tissue are hemoglobin, oxyhemoglobin, melanin, and water [3]. These four chromophores are also distributed spatially within oral tissue. Water and melanin, for example, reside in the 100-300 µm-thick epithelium [4], while water, hemoglobin, and oxyhemoglobin reside in sub-epithelium (lamina propria and submucosa) [5], as illustrated in Figure 1. -

Breast Care / Breast Cancer
BREAST CARE / BREAST CANCER Overview The Kaiser Permanente Breast Care Management Algorithm provided on this site was developed by the Inter-Regional Breast Cancer leaders group (IRBC). This multidisciplinary group includes physicians from Primary Care, Surgery, Oncology, Obstetrics and Gynecology, Radiology, Mammography, Genetics and Women’s Services and representatives from various regional Breast Cancer Task force groups, Clinical Nursing, Quality Resource & Risk Management, Public Relations & Issues Management, Prevention Services, and the Permanente Federation. The algorithm was developed to: • Improve the quality of care for our members with breast complaints, • Improve the timeliness of the identification of breast abnormalities and diagnosis of breast cancer, • Improve the satisfaction of members with breast complaints, and • Respond to the increase in malpractice allegations of failure to diagnose breast cancer. In 2002, the IRBC group held periodic conference calls to develop information to assist primary care clinicians in improving the quality of care for patients with breast complaints. A multidisciplinary consensus-based method was used to develop the content of the algorithm. The group also identified additional information and resources available internally and externally which would support implementation.The Breast Care Leaders in each Region have been encouraged to review and modify the algorithm to reflect local operations. Therefore, prior to use, PCPs are advised to contact a Regional member of the Inter-Regional Breast Care leaders group about revisions for your Region This site is for use within Kaiser Permanente only. What is Available on this Site? The IRBC group and the project management staff from the Permanente Federation worked together to define the project scope and develop the following products and information: I. -

Using Next Generation Science to Understand the Normal Breast and the Development of Breast Cancer Conference Report Dr. Susan Love Research Foundation is committed to performing and advancing research that will lead to the discovery of what causes cancer to develop in the human breast. As part of this effort, the Foundation hosted the 8th International Symposium on the Breast in Santa Monica, Calif., Feb. 19-21, 2015. More than 120 forward-thinking clinical researchers, epidemiologists, pathologists, basic scientists, translational investigators, and breast cancer advocates from six countries attended this year’s conference, “Using Next Generation Science to Understand the Normal Breast and the Development of Cancer.” The Symposium was organized around three central topics: the anatomy and molecular biology of the breast and cancer risk; the microenvironment and microbiome of the normal and cancerous breast; and clinical applications of next generation science. During the conference, attendees also had the opportunity to observe live demonstrations of nipple aspirate fluid collection, ductal lavage, and ductoscopy. A Public Panel allowed the community to hear highlights of the Symposium and gain insight into new directions in breast cancer research. On the final day of the conference, Dr. Susan Love Research Foundation awarded a total of $70,000 to support four multidisciplinary consortia formed at the Symposium that will conduct research focused on using next generation technology to investigate the human breast and how it develops cancer. Introduction Recent advances in technology have created new opportunities in breast cancer research. Dr. Susan Love Research Foundation’s 8th International Symposium on the Breast fostered an intimate think-tank environment where researchers, clinicians, and breast cancer advocates 1 could discuss and explore ways to use these new technologies to obtain long-sought answers to critical questions on how breast cancer develops. -

Bille Abstract Age-related macular degeneration (AMD) is a retinal disease that affects the retinal pigment epithelium (RPE) cells in the macular region. It is the lead- ing cause for blindness in the Western world. In the RPE, enlarged lipofuscin granules show autofluorescence that is monitored through confocal scanning laser ophthalmoscope (cSLO) in clinical practice today. This work focuses on a new approach. The lipofuscin is imaged by means of a two-photon excited fluorescence (TPEF) ophthalmoscope. This offers intrinsic three dimensional resolution and a larger sensing depth. A conven- tional cSLO (HRT, Heidelberg Engineering, Germany) has been modified for TPEF imaging at video rate speed (20 Hz). Two different femtosecond (fs) lasers have been used for the setup. A mode- locked Ti:Sa laser (Mira 900, Coherent, USA) and a compact, all diode- pumped, solid-state Nd:glass fsd oscillator (femtoTRAINTM Nd-Glas V1.0, High Q Laser, Austria). The first images of the high-speed TPEF ophthalmoscope on retinas from donor eyes are presented. The results show the potential for in vivo TPEF imaging of the human eye in everyday clinical use.
