PURPOSE: To characterize posterior corneal surface features in patients with keratoconus and healthy controls and correlate them with the severity of the disease according to visual limitation. METHODS: Retrospective, comparative, clinical study including 477 cases, 374 keratoconic eyes and 103 healthy corneas. Patients were classified according to the degree of visual limitation. The corneal posterior surface including shape indices and keratoconus screening indices was evaluated using the rotating Scheimpflug camera and Placido disc topographer...

PURPOSE: The purpose of this study was to: 1) compare scanners output by measuring normalized CTDIw (mGy/100mAs) in different CT makes and models and at different kV's, and 2) quantify the relationship between kV and CTDI and compare this relationship between the different manufacturers. METHODS: Study included forty scanners of major CT manufacturers and of various models. Exposure was measured at center and 12 o'clock holes of head and body CTDI phantoms, at all available kV's, and with the largest or second largest available collimation in each scanner...

BACKGROUND: The aim of this review is to provide an overview about health services research in Bavarian primary care. METHODS: The academic development of general practice and the associated health services research is described within this narrative -review. RESULTS: Health services research is a heterogeneous field which might be best described for primary care as "research along the last mile of the health care System". Various elements are evolving in Bavarian primary care research, like investigation of diagnostic issues, impact of psychosomatic co-morbidity on patient management and maintenance of medical services in rural areas...

Since the late 1980s implantation of UV-blocker intraocular lenses during cataract surgery has become an internationally accepted standard. Last year the Kassenärztliche Vereinigung Bayern (KVB) and statutory health insurance organisations proposed for the first time quality criteria for intraocular lenses (IOL), thereby including exact parameters for the amount of UV light transmission (≤10% at 400 nm). Since then, the discussion has been raised again as to what extent IOLs should filter or block UV light...

AIM: Germany's growing shortage of doctors is a current topic of numerous discussions in healthcare policy. The objective of this study is to show the medical supply situation and migratory movement of doctors in the outpatient and inpatient physician care sector, with particular emphasis on the immigration of foreign doctors to Germany and its consequences. SUBJECTS AND METHODS: The annual statistical reports from the Bavarian Medical Association and the Federal Medical Association were investigated with regard to foreign doctors and migratory movements...

BACKGROUND: Vertigo and dizziness are common symptoms leading patients to consult a physician. The nationally representative "2003 Health Survey" depicts the epidemiology of the symptoms vertigo and dizziness across all of Germany. A breakdown of the data by region is not available. METHODS: Routine data of the Bavarian Association of Statutory Health Insurance Physicians accounting centre ("Kassenärztliche Vereinigung Bayerns", KVB) from 2008 were analysed using multilevel models to investigate individual and regional factors and the relevance of nonspecific regional heterogeneity...

Occupational exposure to non-ionising electromagnetic radiation emitted by train protection (TP) systems operating at ∼27 MHz is investigated in situ. In total, five TP systems of two different types, i.e. KVB (Contrôle de Vitesse par Balises) and TBL1+ (Transmission Balise-Locomotive), are considered. For each type, the boundaries outside which the field levels are in compliance with the International Commission on Non-Ionizing Radiation Protection guidelines for occupational exposure ('compliance boundaries') are determined...

AIM OF THE STUDY: Differences in health care in Germany have rarely been analysed. Recent research, however, indicates that subjects of the lower social class participate in cancer screening less frequently. METHODS: Participation in screening for cervical cancer among women older than 20 years has been analysed using billing information of the KVB (Kassenärztlichen Vereinigung Bayern) for the period from 2002-2005. Women were assigned to one of the 96 Bavarian districts based on their postal code...

PURPOSE: Over 20,000 patients have been treated with partial breast irradiation (PBI) using the MammoSite balloon brachytherapy applicator (IBB). Recently, a new form of balloon-based PBI, Xoft Axxent electronic brachytherapy (KVB), which uses a 50-kV x-ray source, has been introduced. This analysis was undertaken to dosimetrically compare the results of treatment using these two methods of PBI. METHODS AND MATERIALS: The study population consisted of 15 patients previously treated with IBB...

In this paper, we suggest a simple representation for notation of Kekulé valence bond (KVB) structures and longer range resonance valence bond (RVB) structures, which is called "the adjacency bonding array". In this representation, only an N component one-dimensional array is needed for inscribing each KVB or longer range RVB structure for an N-carbon system. Based on the adjacency bonding arrays, we develop very efficient algorithms for the systematic search of KVB and RVB structures as well as evaluation of the basis set overlap and Hamiltonian matrices...

OBJECTIVE: To investigate the relationship between the expression of glucosylceramide synthase (GCS) mRNA in vincristine-resistant KBV(200) human cancer cell line and multidrug resistance (MDR) of the cancer cells. METHODS: Reverse transcriptional polymerase chain reaction (RT-PCR) was employed to analyze the differential expression of GCS mRNA between KBV(200) and KB cell lines and the changes in the mRNA expressions of GCS and mdr1 gene in KBV(200) cells after reversion of MDR...

Private veterinary practice has existed in Kenya for more than half a century. Between the early 1930s and the mid-1960s, provision of clinical and advisory services almost entirely involved servicing commercial ranches and dairy farms. The Department of Veterinary Services (VSD) was mainly responsible for providing regulatory services in these areas. Until the mid-1960s, public sector veterinary responsibilities were predominantly associated with the prevention of notifiable diseases outside the commercial farming areas...

RATIONALE AND OBJECTIVES: In January 2002, the Bavarian Statutory Health Care Administration ("Kassenärztliche Vereinigung Bayerns", KVB) started a recertification program for quality assurance and quality improvement in mammography reading. MATERIALS AND METHODS: All accredited radiologists and gynecologists are asked to prove their qualification every 1-2 years. The recertification program requires the physicians to read 50 cases randomly selected from a larger collection of high-quality test cases...

One of the results of the 49th Bavarian Physician's Conference was that in 1996 the Bavarian Statutory Health Care Administration (Kassenärztliche Vereinigung Bayerns, KVB) and the Bavarian Medical Association (Bayerische Landesärztekammer, BLAK) jointly suggested a project for the development and verification of a security infrastructure for the online transmission of medical patient data. This Project, the so-called "Health Care Professionals Protocol" (HCP-Protokoll), was designed to establish the first consensus standard for a secure and probably open system to be used in the health care system operating under the constraints of the diverse and heterogeneous IT-infrastructure in Bavaria, with a view towards utilization in all of Germany...
