We present results of anisotropy and exchange-coupling studies of asymmetric Co/Cr/Fe trilayers and superlattices grown by molecular beam epitaxy on Cr͑001͒/Mg͑001͒ buffers and substrates. The magnetic properties have been investigated using both the longitudinal magneto-optical Kerr effect and ferromagnetic resonance. The hysteresis data obtained from the trilayer system were fit to a theoretical model which contains both bilinear and biquadratic coupling. The effective in-plane anisotropy was found to be of fourfold symmetry with the same easy-axis orientation for both the Fe and Co layers. An analysis of the easy-axis hysteresis loops indicates long-period oscillatory coupling and also suggests a short periodic coupling. We show that weakly antiferromagnetically coupled asymmetric films might serve as potential candidates for improved spin-valve systems.

We report a case of a 54-year-old man with an angioleiomyoma originating from the right nasal floor. Nasal vascular leiomyomas are extremely rare tumours. A review of the literature revealed a limited number of cases of vascular leiomyoma in the nasal cavity. Clinically, they are characterised by nasal obstruction, epistaxis or pain as the primary symptom. Up to our knowledge, this is the first case in which a 3D CT scan was performed preoperatively. 3D CT scan reconstructions can show the delineation of the tumour very accurately helping to establish the therapeutic plan for removal. The definite diagnosis can only be confirmed by histopathology. Histopathologically, a vascular leiomyoma demonstrates proliferation of smooth muscle cells intermingled with dilated venous vessels.

Since there are currently no interesting treatment options for men with early-stage Dupuytren's disease, new, safe and effective treatment methods are required to improve the quality of life of such patients. Over the past decade, isotonic sugar water injections have received increasing attention from clinicians worldwide. Glucopuncture is a new term to describe isotonic sugar water injections into dermis, fascia, muscles, tendons and ligaments. In this clinical case, a 75-year-old man was treated with glucopuncture for a painless nodule on the right hand. A marked reduction in hardness and size of the nodule was observed after six sessions. Establishing a case series with imaging before and after treatment could be a first step to further illustrate the effects of this novel injection technique. Next, randomized controlled trials (RCTs) with sufficient sample size are needed to establish the value of glucopuncture for painless nodules in Dupuytren's disease.
