We described two clinical cases of ortho-k lenses fitting in patients with “non-typical” corneal curvature/diameter ratio. The main goal was to acknowledge effective and safe use of this myopia correction method in patients with corneal diameter greater than 11 mm. Individual approach to each patient is the key to a successful and safe ortho-k lenses fitting.

We described clinical cases of scleral lenses fitting in patients with induced ametropia and have shown the efficiency of this optical correction. High functional results and comfortable use make scleral lenses the main optical correction method for patients with irregular corneas after refractive surgery procedures.

The aim of the study was the analysis of domestic and foreign medical literature of different time periods, which describes the basic methods of surgical and conservative treatment of congenital or habitual dislocation of patella, as well as statistical analysis of the results of treatment. Due to the existence of a large number of options of surgical treatment for this pathology (more than 150 methods were developed) and high variability of its manifestations, it is necessary to know the basic methods and their results for planning tactics of treatment with individual approach to each patient. Based on this review, analysis was performed for the results of using different options for invasive treatment of congenital or habitual dislocation of patella. Also, the paper contains the indications and efficacy of conservative therapy for this disease. A comparative analysis was made on the results of surgical and conservative methods of treatment of patellar dislocation, which were used in different time periods, from the initial description of the first results of treatment of this pathology to modern surgical techniques that are currently used. It is shown that all methods of surgical treatment of the pathology are divided into three main groups: myofascioplastic surgeries, osteoplastic and combined surgical interventions. It is underlined that the diseases requires individual approach to the choice of correction method in each certain case to achieve positive outcomes.

Electron Energy Loss Spectra

The normal method of background subtraction in quantitative EELS analysis involves fitting an expression of the form I=AE-r to an energy window preceding the edge of interest; E is energy loss, A and r are fitting parameters. The calculated fit is then extrapolated under the edge, allowing the required signal to be extracted. In the case where the characteristic energy loss is small (E < 100eV), the background does not approximate to this simple form. One cause of this is multiple scattering. Even if the effects of multiple scattering are removed by deconvolution, it is not clear that the background from the recovered single scattering distribution follows this simple form, and, in any case, deconvolution can introduce artefacts.The above difficulties are particularly severe in the case of Al-Li alloys, where the Li K edge at ~52eV overlaps the Al L2,3 edge at ~72eV, and sharp plasmon peaks occur at intervals of ~15eV in the low loss region. An alternative background fitting technique, based on the work of Zanchi et al, has been tested on spectra taken from pure Al films, with a view to extending the analysis to Al-Li alloys.

Recent studies indicate there is some disagreement concerning the interpretation and clinical utility of the Type V Bekesy pattern. Bekesy tracings obtained over the past six years from a sample of clinical cases were analyzed and a definition was established for the Type V pattern. This definition was applied to Bekesy tracings obtained from normal listeners, hypoacusics, and pseudohypoacusics. The Type V pattern was found frequently among pseudohypoacusics and only rarely among other individuals.
