[Impact of a more stringent organization of intravitreal injection treatment on the number of treatments and examinations in routine practice]. / Auswirkungen einer stringenteren IVOM-Behandlungsorganisation auf die Anzahl der Behandlungen und Untersuchungen im Praxisalltag.

BACKGROUND: Results from recent studies show that less intravitreal injections are often performed in everyday practice than in controlled trials, which subsequently leads to worse treatment success. In this study we analyzed the introduction of a more stringent organization of treatment using workflow optimization and new IT systems and analyzed the effect on treatment continuity. MATERIAL AND METHODS: In the second quarter of 2019 a new medical practice management software and a software for automated injection planning were implemented. There was also a change of the treatment regimen from pro re nata (PRN) to treat and extend (T&E ). We analyzed the results of the patients regarding the frequency of injections and treatment controls three quarters before (Q3/2018-Q1/2019) and three quarters after the change (Q2/2019-Q4/2019). Treatment-naive and pretreated patients were analyzed. RESULTS: In group 1 (Q3/2018-Q1/2019) the average number of injections per quarter was 1.74 (SD = 0.4). Eyes of patients from group 2 (Q2/2019-Q4/2019) received on average 2.17 (SD = 0.3) injections. The number of check-ups per quarter was 1.71 (SD = 0.3) before the introduction, and thereafter 2.16 (SD = 0.3). There was a significant increase in the number of OCTs from 1.18 (SD = 0.2) to 1.98 (SD = 0.3). The visual acuity was stable in both groups. CONCLUSION: We were able to show that the introduction of the medical practice management software and the change of the regimen from PRN to T&E can achieve numbers of injections, check-ups and OCT similar to those in studies. A standardized procedure facilitates efficient treatment planning and enables a better patient management.

Evaluation of patient satisfaction with an ophthalmology video consultation during the COVID-19 pandemic.

BACKGROUND: We introduced a video consultation (VC) during the coronavirus (COVID-19) pandemic in an ophthalmology practice with eight doctors to ensure continuous ophthalmological care, infection prophylaxis and to compensate a decreased number of patient presentations. OBJECTIVE: Evaluation of the most common reasons for patient presentations in the VC, the proportion of re-presentations in the practice despite VC, practical challenges associated with the introduction of VC and patient satisfaction. MATERIAL AND METHODS: Patients with a recent acute visual deterioration and severe eye pain were excluded from the VC. The VC were carried out by a trained specialist in ophthalmology. A questionnaire with eight questions was completed after the VC appointment in order to evaluate the proportion of completed VC and patient satisfaction. RESULTS: We included 29 (13 male, Ø 52.6 years, 16 female, Ø 64.7 years) patients in this analysis. The VC could be performed with 68.97% of the participants who rated their overall experience with an average grade of 1.6 (1 very good to 6 insufficient) and all of them indicated that they would recommend the VC. Of presentations in VC 70% were related to the symptoms of the anterior eye segment. In 70% of the cases no re-presentations took place in the unit. CONCLUSION: Our study represents a significant practical application of VC for the management of non-urgent ocular conditions with maximum infection prophylaxis. The introduction of VC was severely limited by technological or user-related issues by the establishment of video connections. Patient satisfaction with VC was high to very high.

New aspects of longitudinal instabilities in electron storage rings.

Novel features of the longitudinal instability of a single electron bunch circulating in a low-emittance electron storage ring are discussed. Measurements and numerical simulations, performed both in time and frequency domain, show a non-monotonic increase of the electron beam energy spread as a function of single bunch current, characterized by the presence of local minima and maxima, where a local minimum of the energy spread is interpreted as a higher-order microwave instability threshold. It is also shown that thresholds related to the same zero-intensity bunch length depend linearly on the accelerating radio frequency voltage. The observed intensity-dependent features of the energy spread, confirmed by measurements with two independent diagnostics methods, i.e. horizontal beam profile measurements by a synchrotron light monitor and photon energy spectrum measurements of undulator radiation, are given a theoretical interpretation by applying a novel eigenvalue analysis based on the linearized Vlasov equation.

[The extent of the concept and the diagnostic criteria of psychopathy based on catamnestic data. I. The spectrum of psychopathic disorders. II. Organic pathology and psychopathy]. / Ob''em poniatiia i kriterii diagnostiki psikhopatii po dannym katamneza. I. Spektr psikhopaticheskikh rasstroistv. II. Organicheskaia patologiia i psikhopatiia.

A study covering 277 psychopathic patients has been aimed at specifying the notion of psychopathy as well as the criteria of its diagnosis with the help of follow-up findings. Psychopathies are considered as a transient status of protracted adaptation due to retardation of the pubertal period. The study of "true" psychopathy has demonstrated that psychic disturbances are transitory and determined typologically by manifestations of neurosis or neurotic development. Persistent and prolonged psychopathy-like disturbances (n = 233) are referred to groups of other diseases.A total of 118 psychopathic patients have been subjected to a prolonged follow-up. The findings obtained have demonstrated a variety of organic cerebral diseases from traumatic encephalopathy to oligophrenia. The authors raise a question as to the validity of the generally accepted criteria of psychopathy in the framework of the so-called "organic psychopathy". A suggestion is put forward that abuse of the diagnosis of psychopathy in organic diseases of the central nervous system leads to the erroneous therapeutic strategy and corresponding social restrictions.
