PURPOSE OF REVIEW: This review highlights the current status of endoscopic retrograde cholangiopancreatography (ERCP) techniques in patients with altered anatomy. Endoscopic treatment of biliopancreatic disorders is particularly challenging in patients with altered anatomy. RECENT FINDINGS: There are two main approaches to perform ERCP in patients with altered anatomy: the transluminal access and the transmural access. The transluminal access uses device-assisted enteroscopy (DAE) to reach and cannulate the biliopancreatic system...

Stabilization of pelvic ring injuries and certain acetabular fractures using percutaneous techniques is becoming increasingly more common. Intramedullary superior ramus screw fixation is beneficial in both injury types. While implants can be placed in an antegrade or retrograde direction, parasymphyseal ramus fractures benefit from retrograde implant insertion. In some patients, the parabolic osseous anatomy or obstructing soft tissues of the anterior pelvis or thigh can prevent appropriate hand and instrumentation positioning for appropriate retrograde ramus screw insertion through the entire osseous fixation pathway...

Soft tissue sarcoma of the forearm, wrist and hand are rare. Their benign appearance leads often to primary inadequate treatment. Due to the complex anatomy of the hand and forearm, they are challenging to treat. The two goals are to obtain wide resection of the primary tumor while preserving function. Limb-sparing surgery is now the cornerstone for the treatment of most sarcomas of the forearm, hand and wrist. To achieve optimal oncological and functional outcomes, the surgical excision should be associated with early reconstructive procedures and a multidisciplinary meeting to define the treatment strategy including adjuvant medical treatments...

The evolution of primates is intimately linked to their initial invasion of an arboreal environment. However, moving and foraging in this milieu creates significant mechanical challenges related to the presence of substrates differing in their size and orientation. It is widely assumed that primates are behaviorally and anatomically adapted to movement on specific substrates, but few explicit tests of this relationship in an evolutionary context have been conducted. Without direct tests of form-function relationships in living primates it is impossible to reliably infer behavior in fossil taxa...

REVIEW
Florian Kurth, Nicolas Cherbuin, Eileen Luders
Over the last decade, an increasing number of studies has reported a positive impact of meditation on cerebral aging. However, the underlying mechanisms for these seemingly brain-protecting effects are not well-understood. This may be due to the fact, at least partly, that systematic empirical meditation research has emerged only recently as a field of scientific scrutiny. Thus, on the one hand, critical questions remain largely unanswered; and on the other hand, outcomes of existing research require better integration to build a more comprehensive and holistic picture...

BACKGROUND: Synovial chondromatosis is characterized by cartilaginous metaplasia in synovial tissues. Extra-articular tenosynovial chondromatosis is considered to be an anatomical counterpart of articular synovial chondromatosis. Extra-articular tenosynovial chondromatosis occurs preferentially in the hand, although its frequency is low. RESULTS: We report three cases of extra-articular tenosynovial chondromatosis. A 65-year-old female presented with a history of symptoms over 40 years related to the dorsum of her index finger (Case 1), A 46-year-old female presented with a 6-month history of symptoms at the volar surface of her middle finger (Case 2), and a 66-year-old male presented with a 3-month history of symptoms in a dorsal ring finger...

OBJECTIVE: Laparoscopic cholecystectomy is considered to be gold standard treatment for symptomatic gall stones. Despite several benefits there are still disadvantages of laparoscopic cholecystectomy in difficult cases where anatomy is disturbed even in experienced hand. Aim of this study is to identify advantages of early conversion to open cholecystectomy in difficult cases and how it should not be associated with surgeon's failure. METHODS: Observational study was conducted at tertiary care hospital of Karachi, Pakistan from January 2012 till June 2015...

We report a rare combination of variations in the upper limb of a human cadaver. Accessory flexor carpi ulnaris with absent palmaris longus was observed in the left forearm during routine dissection of a male cadaver. Variant vascular pattern was observed bilaterally. Brachial artery bifurcated at a higher level. Ulnar artery gave rise to persistent median artery (PMA) which pierced the median nerve and accompanied it deep into flexor retinaculum to terminate as two common palmar digital arteries. Superficial palmar arch was not formed as the PMA did not anastomose with either the radial or ulnar artery...

Rapidly growing global population adds significant strains on the fresh water resources. Consequently, saline water is increasingly tapped for crop irrigation. Meanwhile, rapid advancement of nanotechnology is introducing more and more engineered nanoparticles into the environment and in agricultural soils. While some negative effects of ENPs on plant health at very high concentrations have been reported, more beneficial effects of ENPs at relatively low concentrations are increasingly noticed, opening doors for potential applications of nanotechnology in agriculture...

Living anatomy is gaining increasing popularity as an alternative to the use of preserved cadaver specimens in musculoskeletal anatomy teaching. This article describes the development of a garment painted with musculoskeletal structures as an alternative to body painting. Garments offer some advantages over traditional body painting in anatomy teaching. The technique can be used across different disciplines, enhances students' ability to identify anatomic structures in living bodies, and provides insights into the topography of one or more body systems at the same time...

In neonate ruminants, the acoustic structure of vocalizations may depend on sex, vocal anatomy, hormonal profiles and body mass and on environmental factors. In neonate wild-living Mongolian gazelles Procapra gutturosa, hand-captured during biomedical monitoring in the Daurian steppes at the Russian-Mongolian border, we spectrographically analysed distress calls and measured body mass of 22 individuals (6 males, 16 females). For 20 (5 male, 15 female) of these individuals, serum testosterone levels were also analysed...

In the anatomical sciences, e-learning tools have become a critical component of teaching anatomy when physical space and cadaveric resources are limited. However, studies that use empirical evidence to compare their efficacy to visual-kinesthetic learning modalities are scarce. The study examined how a visual-kinesthetic experience, involving a physical skeleton, impacts learning when compared with virtual manipulation of a simple two-dimensional (2D) e-learning tool, A.D.A.M. Interactive Anatomy. Students from The University of Western Ontario, Canada (n = 77) participated in a dual-task study to: (1) investigate if a dual-task paradigm is an effective tool for measuring cognitive load across these different learning modalities; and (2) to assess the impact of knowledge recall and spatial ability when using them...

Situs inversus totalis is a rare congenital condition, characterized by the transposition of the thoracic and abdominal viscera, resulting in a mirror image of normal anatomy. Even though situs inversus does not predispose to gall stones, a laparoscopic cholecystectomy, in a case of situs inversus, can prove to be a technically challenging procedure, especially for the right-handed surgeon. In this case report, we present an unusual case of cholelithiasis in a patient with situs inversus totalis. A laparoscopic cholecystectomy, which is considered the gold standard procedure for symptomatic gallstones, was performed...

INTRODUCTION: Ultrasound-guided thrombin injection (UGTI) is a well-established practice for the treatment of femoral artery pseudoaneurysm. This procedure is highly successful but dependent on appropriate pseudoaneurysm anatomy and adequate ultrasound visualization. Morbid obesity can present a significant technical challenge due to increased groin adiposity, resulting in poor visualization of critical structures needed to safely perform the procedure. We aim to evaluate the safety and efficacy of UGTI to treat femoral artery pseudoaneurysm in the morbidly obese...

INTRODUCTION/PURPOSE: Arterial injury in the hand is most often due to repetitive blunt trauma. Although not always associated with significant impairment, it may cause serious ischemic damage or considerable disability. As a cause of digital ischemia, the frequency of this disorder is widely under appreciated. This study reviews the clinical and angiographic features of this condition. MATERIALS/METHODS: An extensive literature review combined with the authors experience with arterial injury in the hand due to repetitive blunt hand trauma is summarized with emphasis on mechanisms of injury and pathologic changes to explain the angiographic findings and clinical presentations...

We reported a rare peripheral nerve case, a patient developed carpal tunnel syndrome with a history of floating thumb in right hand. The median nerve was found expanded and spindle-shaped and a plexiform neurofibroma was diagnosed. Our case sheds light on anatomy and possible etiological association which may help clinical management.

Clinical assessment of the hand is important for diagnosing underlying hand disorders. Using a case study approach, the clinical assessment for three disorders of the hands is presented: trigger finger (stenosing tenosynovitis), carpal tunnel syndrome, and ulnar-sided wrist injury (styloid impingement). We assess the annular one pulley and finger range of motion for patients with trigger finger. To diagnose for carpal tunnel syndrome, assessment for Tinel's sign, Phalen's sign, abductor pollicis brevis muscle bulk, two-point discrimination, and obtaining a nerve conduction study are performed...
