Ileocaecal tuberculosis: an under-recognised cause of vitamin B deficiency.

Trop Doct 2018 Dec 12:49475518816590. Epub 2018 Dec 12.

2 MD Resident, Department of Internal Medicine, Post Graduate Institute of Medical Education and Research, Chandigarh, India.

A combination of anaemia and knuckle pigmentation should always raise concern for megaloblastic anaemia. As the terminal ileum is the site of vitamin B absorption and also the commonest site of abdominal tuberculosis, a clinical triad of prolonged fever, knuckle pigmentation and right lower quadrant abdominal tenderness should suggest ileocaecal tuberculosis in endemic areas.

Great ape thorax and shoulder configuration-An adaptation for arboreality or knuckle-walking?

J Hum Evol 2018 Dec 16;125:15-26. Epub 2018 Oct 16.

Department of Anatomical Sciences, Stony Brook University School of Medicine, Stony Brook, NY 11794-8081, USA.

Great apes exhibit a suite of morphological traits of the shoulder and upper thorax that have traditionally been linked to orthograde arborealism. Recently it has been proposed that these traits are instead adaptations for knuckle-walking, and more broadly, that knuckle-walking itself is an adaptation for shock absorption during terrestriality. Here we test several tenets of these hypotheses using kinematic and kinetic data from chimpanzees and macaques, and electromyographic data of shoulder muscle activity in chimpanzees. Read More

Biomarkers of erosive arthritis in systemic lupus erythematosus: Application of machine learning models.

PLoS One 2018 4;13(12):e0207926. Epub 2018 Dec 4.

Lupus Clinic, Rheumatology, Dipartimento di Medicina Interna e Specialità Mediche, Sapienza Università di Roma, Rome, Italy.

Objective: Limited evidences are available on biomarkers to recognize Systemic Lupus erythematosus (SLE) patients at risk to develop erosive arthritis. Anti-citrullinated peptide antibodies (ACPA) have been widely investigated and identified in up to 50% of X-ray detected erosive arthritis; conversely, few studies evaluated anti-carbamylated proteins antibodies (anti-CarP). Here, we considered the application of machine learning models to identify relevant factors in the development of ultrasonography (US)-detected erosive damage in a large cohort of SLE patients with joint involvement.

Volar Resurfacing of the Thumb with a Superficial Circumflex Iliac Artery Perforator Flap after Hydrofluoric Acid Burn.

J Hand Microsurg 2018 Dec 5;10(3):162-165. Epub 2018 Apr 5.

Division of Plastic Surgery, University of Colorado, Aurora, Colorado, United States.

A right-hand-dominant 55-year-old male automotive mechanic presented 24 hours following a hydrofluoric acid burn to the volar left thumb. Despite the severity of soft tissue injury, the neurovascular bundles were intact. Although a free toe-pulp flap is often described to cover volar digit defects, the resultant 6- × 4-cm full-thickness injury of the thumb was too large to be adequately covered by a toe-pulp flap or other commonly used local flaps from the ipsilateral hand.

Pianism: Performance Communication and the Playing Technique.

Authors:
Barbara James

Front Psychol 2018 5;9:2125. Epub 2018 Nov 5.

School of Human Movement and Nutrition Sciences, The University of Queensland, Brisbane, QLD, Australia.

A pianist's movements are fundamental to music-making by producing the musical sounds and the expressive movements of the trunk and arms which communicate the music's structural and emotional information making it valuable for this review to examine upper-body movement in the performance process in combination with the factors important in skill acquisition. The underpinning playing technique must be efficient with economic muscle use by using body segments according to their design and movement potential with the arm segments mechanically linked to produce coordinated and fluent movement. Two physiologically and pianistically important actions proposed by early music scientists to deliver the keystroke involve dropping the hand from the shoulders toward the keys via a wave action with the joints activated sequentially, and forearm rotation to position the fingers for the keystroke, an action followed by the elbow/upper-arm rotating in the opposite direction.

Extraction of Aortic Knuckle Contour in Chest Radiographs Using Deep Learning.

Conf Proc IEEE Eng Med Biol Soc 2018 Jul;2018:5890-5893

In this paper, we aim to extract the aortic knuckle (AK) contour in chest radiographs, an anatomical structure rarely being addressed in the literature. Since the AK structure is small and thin, simply adopting the deep network methods that are successful for large organ segmentation is inadequate for achieving good pixel-level accuracy and resolving local ambiguities. To address this challenge, we propose a new coarse-to-fine segmentation approach which focuses on global and local information contexts, respectively. Read More

Inverse remodelling algorithm identifies habitual manual activities of primates based on metacarpal bone architecture.

Biomech Model Mechanobiol 2018 Nov 9. Epub 2018 Nov 9.

Institute of Lightweight Design and Structural Biomechanics, TU Wien, Getreidemarkt 9/BE, Vienna, Austria.

Previously, a micro-finite element (micro-FE)-based inverse remodelling method was presented in the literature that reconstructs the loading history of a bone based on its architecture alone. Despite promising preliminary results, it remains unclear whether this method is sensitive enough to detect differences of bone loading related to pathologies or habitual activities. The goal of this study was to test the sensitivity of the inverse remodelling method by predicting joint loading histories of metacarpal bones of species with similar anatomy but clearly distinct habitual hand use.

The third metacarpal has been a focus of study when examining questions surrounding early hominin locomotion since this bone is adapted to the diverse range of positional behaviors performed by extant hominoids. The shape of this bone is potentially under strong selective pressure related to the biomechanical demands of terrestrial knuckle-walking, arboreal clambering, and brachiation performed by extant hominoids since the hand directly interacts with the substrate during the performance of these movements. The objective of the present study was to explore shape variation of the third metacarpal and examine how different parts of the bone discriminated between hominoid genera that perform these different locomotor behaviors.

Trabecular Bone Structural Variation in the Proximal Sacrum among Primates.

Anat Rec (Hoboken) 2018 Oct 13. Epub 2018 Oct 13.

Department of Anthropology, Stony Brook University, Stony Brook, New York.

The sacrum occupies a functionally important anatomical position as part of the pelvic girdle and vertebral column. Sacral orientation and external morphology in modern humans are distinct from those in other primates and compatible with the demands of habitual bipedal locomotion. Among nonhuman primates, however, how sacral anatomy relates to positional behaviors is less clear. Read More

Clinical Examination of the Extensor Pollicis Brevis: Anatomical Study and Description of a Novel Clinical Sign.

J Hand Surg Asian Pac Vol 2018 Sep;23(3):330-335

§ Hand Surgery Unit, St Vincent's Public Hospital, Fitzroy, VIC, Australia.

Background: The Extensor Pollicis Brevis (EPB) is an extrinsic thumb muscle whose main function is extension of the first metacarpophalangeal joint (MCPJ). It is subject to significant anatomical variation and may be absent, vestigial or have an anomalous distal attachment. Clinical examination of EPB is notoriously difficult and no reliable test has yet been described. Read More

Ulnar Subluxation of the Extensor Pollicis Longus Tendon as a Cause of Congenital Clasped Thumb: A Case Report.

J Hand Surg Asian Pac Vol 2018 Sep;23(3):408-411

* Department of Orthopaedic Surgery, Tsuchiura Kyodo Hospital, Tsuchiura, Japan.

A 15-year-old male patient presented with difficulty extending his right thumb due to subluxation of the extensor pollicis longus (EPL) tendon. Physical examination showed that active motion of the thumb's metacarpophalangeal (MP) joint was 76° in flexion and -58° in extension. During active extension, the EPL tendon shifted onto the ulnar aspect of the MP joint, and the extensor pollicis brevis (EPB) tendon shifted onto the central dorsal course of the MP joint. Read More

Severe calcium pyrophosphate dihydrate deposition disease of the metacarpophalangeal joints.

BMJ Case Rep 2018 Sep 28;2018. Epub 2018 Sep 28.

Medicine/Rheumatology, University of Kentucky, Lexington, Kentucky, USA.

We report a case of calcium pyrophosphate deposition disease (CPPD) with an unusual presentation of severe chondrocalcinosis with atypical large burden deposited in the metacarpophalangeal joints as well as more typical deposition in wrists and knees as demonstrated on plain radiographs. A 77-year-old African-American woman 1-year status post parathyroidectomy for hyperparathyroidism initially presented to the rheumatology clinic to treat suspected rheumatoid arthritis given her pattern of joint involvement but was found to have CPPD. The patient's history is notable for end-stage renal disease which complicates medical management. Read More

Tether Creation Between the Second and Third Extensor Digitorum Communis for Third Extensor Tendon Subluxation at the Metacarpophalangeal Joint.

Tech Hand Up Extrem Surg 2018 Dec;22(4):146-149

Yukioka Hospital Hand Center, Osaka Yukioka College of Health Science, Kita-ku, Osaka-shi, Osaka, Japan.

We developed a substitution technique for a sagittal band reconstruction for subluxation of the third extensor tendon at the metacarpophalangeal joint. Through this procedure, we attempted to supply a tether between the second and third extensor digitorum communis (EDC) tendons. A half-slip of the second EDC was interlaced to the third EDC tendon at the level of the third metacarpal head with the metacarpophalangeal joint in full flexion position; this ensured that the interlace of the graft serves as a direct stabilizer against ulnar subluxation.
