BACKGROUND: Borderline personality disorder (BPD) has a pervasive pattern of instability in interpersonal relationships, self-image, and emotions. BPD may be linked to an abnormal brain anatomy, but little is known about possible impairments of the white matter microstructure in BPD or their relationship with impulsivity or risky behaviors. The aims of the present study were to explore the relationship between BPD and diffusion tensor imaging (DTI) parameters and psychological tests. METHODS: We evaluated 35 un-medicated BPD patients in a medication-free state and 50 healthy controls (HCs)...

OBJECTIVES: Rectovaginal fistulas can occur from both obstetric and nonobstetric (eg, inflammatory bowel disease, iatrogenic, or traumatic) etiologies. Current data on factors contributing to rectovaginal repair success or failure are limited, making adequate patient counseling difficult. Our objective was to compare outcomes of transperineal rectovaginal fistula repair performed in a single referral center on women with obstetric and nonobstetric causes. METHODS: We performed a retrospective cohort study of women who had a transperineal rectovaginal fistula repair performed by a urogynecologist at the University of Michigan from 2005 to 2015...

In breast cancer screening or diagnosis, it is usual to combine different images in order to locate a lesion as accurately as possible. These images are generated by using a single or several imaging techniques. As X-ray based mammography is used widespread, a breast lesion is located in the same plane of the image (mammogram), but tracking of a breast lesion across mammograms corresponding to different views is a daring task for medical physicians. According to this, simulation tools and methodologies that use patient-specific numerical models can facilitate the task of fusing information from different images...

The current contrast agents utilized in ultrasound (US) imaging are based on microbubbles which, however, suffer from a short lifetime in the systemic circulation. The present study introduces a new type of contrast agents for US imaging based on bioresorbable Janus nanoparticles (NPs) that are able to generate microbubbles in situ under US radiation for extended time. The Janus NPs were fabricated from porous silicon (PSi) that was modified via a nanostopper technique. The technique was exploited to prepare PSi NPs which had hydrophobic pore walls (inner face) while the external surfaces of the NPs (outer face) were hydrophilic...

Echocardiography is an excellent noninvasive imaging modality for evaluation and follow-up of cardiac lesions, especially coronary artery changes occurring as a result of Kawasaki disease. The information obtained has prognostic implications and can be complemented with other modes of imaging for risk stratification and optimization of both medical and interventional therapy. The aim of this article is to describe the time line of echocardiographic follow-up of patients affected with Kawasaki disease. The classification of coronary artery changes and transthoracic echocardiographic views recommended for detailed evaluation of the coronary arteries are delineated in detail in this report...

W Harth
Aesthetic medicine has in recent decades attained a growing social significance and firm place in the medical profession image. In a short time, a variety of technical procedures and processes have been developed and applied by specialized physicians. A further leading medical discussion regarding the central question "What is beauty" is missing compared with the technologically innovative progress. Beauty is characterized by an individual and subjective pleasure. Social media and fashion trends exert a central influence on common beauty ideals and aesthetic medicine...

Determination of age is one of the most important and vital demand in legal affairs, court and young sports, especially from 7-21 years. There is no established age determination table in our county. So we are dependent upon Galstaun, Bashu & Bashu and other European tables, which sometimes provide misinterpretation and variation of opinion. We should have our own table suitable for our nation. So, this prospective study was carried out in the Department of Radiology and Imaging of Bangabandhu Sheikh Mujib Medical University (BSMMU), Dhaka, Bangladesh from July 2010 to June 2014 (five years) to assess the general skeletal maturity...

OBJECTIVE: Stereoscopic three-dimensional (3D) imaging is increasingly used in the teaching of neuroanatomy and although this is mainly aimed at undergraduate medical students, it has enormous potential for enhancing the training of neurosurgeons. This study aims to assess whether 3D lecturing is an effective method of enhancing the knowledge and confidence of neurosurgeons, and how it compares to traditional two-dimensional (2D) lecturing and cadaveric training. METHODS: Three separate teaching sessions for neurosurgical trainees were organised: i) 2D course (2D lecture + cadaveric session), ii) 3D lecture alone, iii) 3D course (3D lecture + cadaveric session)...

REVIEW
F Moissenet, L Modenese, R Dumas
Musculoskeletal modelling is a methodology used to investigate joint contact forces during a movement. High accuracy in the estimation of the hip or knee joint contact forces can be obtained with subject-specific models. However, construction of subject-specific models remains time consuming and expensive. The purpose of this systematic review of the literature was to identify what alterations can be made on generic (i.e. literature-based, without any subject-specific measurement other than body size and weight) musculoskeletal models to obtain a better estimation of the joint contact forces...

The incidence of renal cell carcinoma (RCC) and metastatic adrenal lesions continues to rise and present evolving complexities in terms of management. Technical challenges in treatment delivery are compounded by the setting of an ageing patient population with multiple medical co-morbidities. While the standard of care treatment for both primary RCC and oligometastatic adrenal lesions has typically been surgery, a number of patients may be medically or surgically inoperable, and for whom alternative options require consideration...

Over the past half-century since Lars Leksell first utilized radiation to address deep and difficult to treat lesions of the central nervous system (CNS), intracranial stereotactic radiosurgery (SRS) has become an increasingly valued tool in the hands of neurosurgeons and radiation oncologists. Following developments in medical imaging and radiation technology, radiosurgery has evolved from its first application in movement disorders to widespread use for a varied range of malignant and benign conditions. SRS remains a powerful, minimally invasive instrument that offers additional options for intervention to a diverse patient population...
