3D computed tomography (CT) visualizations of volumetric data have become an important aspect of diagnostic imaging. The utility of 3D CT has been well described for the imaging of a number of renal pathologies. Recently, a new 3D visualization technique known as cinematic rendering (CR) has become available and provides photorealistic images derived from standard CT acquisitions by use of a complex global lighting model. Herein, we describe a number of normal variant and pathologic conditions of the kidney visualized with CR...

BACKGROUND: Radiocapitellar pathology after traumatic injury to the elbow can be challenging to treat. The anconeus interposition arthroplasty has been proposed to treat radiocapitellar or proximal radioulnar joint dysfunction and pain, or both. This study evaluated whether radial head excision (native or prosthetic), followed by an anconeus interposition arthroplasty, relieves pain and improves subjective and objective elbow function in patients with post-traumatic radiocapitellar pathology...

REVIEW
J Welzel, S Schuh
Optical coherence tomography (OCT) has become established in routine diagnosis in dermatology only in the last few years. The reason is that the skin is a challenge for OCT as a strong scattering medium, because only a very small proportion of photons is reflected and can be used for imaging. In addition, in most cases a visual assessment or a biopsy is sufficient. Nevertheless, the main field of application in dermatology is the diagnostics of epithelial skin tumors. The OCT is suitable for the early recognition of small, clinically and light microscopically unspecific basal cell carcinomas as well as for the differential diagnosis of other tumors and precancerous lesions...

Suture tip plasty is one the most used methods in nasal tip surgery. Transdomal suture (TDS) used for this purpose is utilized for providing the dome symmetry, thinning the nasal tip, and enhancing the nasal tip projection and rotation. However, there are not sufficient visual data on what the dome position should be during TDS. In this study, it was aimed to be directive in tip plasty and to define the convenient dome holding technique during TDS. Patients, 510 male and 621 female at the age of 18 to 50 years, who underwent the open technique septorhinoplasty between the years of 2003 to 2015 were included in the authors' study...

Progress in clinical development of magnetic resonance imaging (MRI) substrate-sensors of enzymatic activity has been slow partly due to the lack of human efficacy data. We report here a strategy that may serve as a shortcut from bench to bedside. We tested ultra high-resolution 7T MRI (µMRI) of human surgical histology sections in a 3-year IRB approved, HIPAA compliant study of surgically clipped brain aneurysms. µMRI was used for assessing the efficacy of MRI substrate-sensors that detect myeloperoxidase activity in inflammation...

Microvascular decompression (MVD) is widely accepted as an effective surgical method to treat trigeminal neuralgia (TN), but the risks of morbidity and mortality must be considered. We experienced a case of acute angle-closure glaucoma attack following MVD for TN in an elderly patient, considered to be caused by lateral positioning during and after the surgery. A 79-year-old female underwent MVD for right TN in the left lateral decubitus position, and TN disappeared after the surgery. Postoperatively, the patient tended to maintain the left lateral decubitus position to prevent wound contact with the pillow, even after ambulation...

Hypertrophic cardiomyopathy (HCM) is a disease with left ventricular hypertrophy caused by mutations in the genes of myocardial contractile proteins, whose frequency is about 0.5 %. Due to the high incidence of anginal pain and marked changes in ECG with HCM, the problem of diagnosing the combination of HCM and coronary artery disease (CAD) presents a rather difficult task for the clinician. The complexity of this diagnosis is due to the ability of standard methods of instrumental examination (ECG, a test with physical activity, stress tests in conjunction with visualization of the myocardium) to detect myocardial ischemia in both СAD and HCM...

Albinism, typically characterized by decreased melanin synthesis, is associated with significant visual deficits owing to developmental changes during neurosensory retina development. All albinism is caused by genetic mutations in a group of diverse genes including enzymes, transporters, G-protein coupled receptor. Interestingly, these genes are not expressed in the neurosensory retina. Further, regardless of cause of albinism, all forms of albinism have the same retinal pathology, the extent of which is variable...
