Paul E Neumann
This is the first in a short series about orthography in anatomical Latin. Although phonology is an important aspect of diphthongs and digraphs, the focus here is on spelling, not the more complicated topic of pronunciation. Recommendations are made for standard spellings of words that contain or may appear to contain diphthongs in Latin anatomical words or their ancient Greek sources. Ligatures and diaereses (typographical symbols that were developed after the classical period) are not recommended for use in anatomical Latin terms...

Little information is available on the length of the normal large intestine and its component parts in children. This information would be useful for procedures such as colonoscopy. The aim of this study was to investigate the length of the large intestine and its component parts in New Zealand children. Archival de-identified pediatric supine abdominopelvic computed tomography (CT) scans were retrospectively analyzed. After exclusion criteria, a total of 112 scans (57 males and 55 females) were included in the study and divided into three age groups: 0-2 years (n=33), 4-6 years (n=40), and 9-11 years of age (n=39)...

INTRODUCTION Chronic dry eye (keratitis sicca) is a significant problem that in certain populations can result in corneal desiccation and the potential for blindness. Therefore, novel treatments for such disorders might decrease patient morbidity. The present study aimed to investigate a potential treatment for chronic dry eye via a cadaveric feasibility study. MATERIALS AND METHODS On 10 cadaveric sides, the parotid gland branch of the auriculotemporal nerve was identified and anastomosed to an anterior superficial temporal branch of this same nerve...

INTRODUCTION: Augmented Realty (AR) offers a novel method of blending virtual and real anatomy for intuitive spatial learning. Our first aim in the study was to create a prototype AR tool for mobile devices. Our second aim was to complete a technical evaluation of our prototype AR tool focused on measuring the system's ability to accurately render digital content in the real world. MATERIALS AND METHODS: We imported Computed Tomography (CT) data derived virtual surface models into a 3D Unity engine environment and implemented an AR algorithm to display these on mobile devices...

This study was designed specifically to determine the normal acetabular orientation and femoral head covering, and whether these are affected by age or sex. Computed tomographic images of normal Japanese hip joints were used (males 60, females 60; mean age 48.3 years, range 15-79 years). Male and female age profiles were matched. The reconstructed 3D pelvic images were aligned in the anatomical pelvic coordinate system. The acetabular orientation angles and femoral covering angles were measured in the sagittal, coronal, and horizontal planes...

It has been demonstrated that the torsional patterns of the metatarsal heads are associated with the presence or absence of the medial longitudinal arch in hominoid feet. The relatively untwisted second metatarsal is unique in humans, but that of the African apes is much more inverted, suggesting that the torsion of the second metatarsal might represent the overall shape and flatness of the foot. Some clinical studies have recently argued that the onset of foot pathologies such as hallux valgus might be related to the torsional pattern of the metatarsals...

There have been many reports on migration of the distal catheter of the ventriculoperitoneal shunt (VPS) since this phenomenon was recognized 50 years ago. However, there have been no attempts to analyze its different patterns or to assess these patterns in terms of potential risk to patients. We comprehensively reviewed all reports of distal VPS catheter migration indexed in PubMed and identified three different anatomical patterns of migration based on catheter extension and organs involved: (1) internal, when the catheter invades any viscus inside the thoracic, abdominal, or pelvic cavity; (2) external, when the catheter penetrates through the body wall either incompletely (subcutaneously) or completely (outside the body); and (3) compound, when the catheter penetrates a hollow viscus and protrudes through a pre-existing anatomical orifice...

INTRODUCTION: Intraocular pressure (IOP) lowering surgery in congenital aniridia glaucoma (CAG) can be complicated by dysgenesis of the limbal region, anterior chamber angle, iris and lens. METHODS: The anterior segments of 23 eyes (17 patients) with congenital aniridia were investigated under general anesthesia using ultrasound biomicroscopy (UBM). The structures of the anterior segment were examined: distance of ciliary body processes from the anterior chamber angle and positioning of Schlemm's canal...

INTRODUCTION: Epithelial invasion after open globe injury is a rare complication. Wrong treatment (laser opening of the cyst) or no treatment can lead to painful blindness. PATIENTS AND METHODS: Forty percent (25/62) of patients with block excision with epithelial downgrowth had a history of open globe injury. Four of them were female. Their mean age was 45 ±21 years. RESULTS: A tectonic keratoplasty with block excision was performed on 25 patients...

REVIEW
Mohammadali M Shoja, Jaspreet Johal, W Jerry Oakes, R Shane Tubbs
Although the Chiari malformations are well-studied and described developmental anomalies, there remains some incongruity in regards to their underlying etiologies. A number of theories have been proposed with the purpose of accounting for the embryology and pathogenesis of the Chiari I and II malformations and their associated complications and clinical syndromes. The present review aims to review the pertinent literature for all of the main theories that have been proposed, and outline their validity and relevance to our contemporary understanding of these anomalies...

PURPOSE: To provide insight into the clinical anatomy of Tenon's capsule and to describe a technique to manage sclerocorneal defects using autologous Tenon's tissue. METHODS: A thin layer of Tenon's capsule harvested from the patient's own eye is used to seal the defect and act as a scaffold. The Tenon's flap is spread over the defect and held in place by Vicryl sutures. A bandage contact lens is then placed on the eye. RESULTS: Tenon's capsule is composed of thick fibrous tissue with smooth muscle fibers and a thin posterior capsule of orbital fat...

INTRODUCTION The sensory innervation of the inferior eyelid is mainly derived from the inferior palpebral branch of the infraorbital nerve. This study aimed to investigate another, to our knowledge, previously unknown branch, and elucidate its location and distribution. MATERIALS AND METHODS Twelve sides from seven fresh frozen cadaveric Caucasian heads were used in this study. The specimens were derived from two male and four female adult cadavers age. The diameter of the inferior palpebral branch of the infraorbital nerve (D1) and branch arising from the upper wall of the infraorbital canal (D2), and distance between the branching points of this branch and the anterior border of the orbit floor (L1) was measured...

INTRODUCTION The debate regarding anatomy laboratory teaching approaches is ongoing and controversial. To date, the literature has yielded only speculative conclusions due to general methodological weaknesses and a lack of summative empirical evidence. Through a meta-analysis, this study compared the effectiveness of instructional laboratory approaches used in anatomy education to objectively and more conclusively synthesize the existing literature. MATERIALS AND METHODS Studies published between January 1965 and December 2015 were searched through five databases...

INTRODUCTION: Anatomical variations in the suprascapular nerve (SSN) and its depth in the suprascapular notch can make it difficult to target with ultrasonography (US). One alternative could be a proximal approach to the SSN, if US provides a reliable description of its origin (orSSN). The primary objective of this study was to demonstrate that US can reliably locate the orSSN. The secondary objective was to describe the features of the proximal SSN. MATERIALS AND METHODS: Seventy brachial plexuses (BP) from 30 healthy volunteers (60 BP) and five cadavers (10 BP) were included...

INTRODUCTION: Three-dimensional (3 D)-scanning-based morphological studies of the face are commonly included in various clinical procedures. This study evaluated validity and reliability of a 3 D scanning system by comparing the ultrasound (US) imaging system versus the direct measurement of facial skin. MATERIALS AND METHODS: The facial skin thickness at 19 landmarks was measured using the three different methods in 10 embalmed adult Korean cadavers. Skin thickness was first measured using the ultrasound device, then 3 D scanning of the facial skin surface was performed...

The issue of co-author relationships on medical sciences journal publications has become more pronounced as advances in technology have enabled collaboration across countries and institutions to occur much more efficiently. These relationships often have underlying political motivations and outcomes, including career advancement, attempting to increase prestige of a project, and maintaining research grants. Some authors may be listed as senior or honorary authors despite offering little or no contribution to the original research project...

The extraocular muscles consist of the superior, inferior, lateral, and medial rectus muscles and the superior and inferior oblique muscles. This study aimed to create a new teaching model for demonstrating the function of the extraocular muscles. A coronal section of the head was prepared and sutures attached to the levator palpebral superioris muscle and six extraocular muscles. Tension was placed on each muscle from a posterior approach and movement of the eye documented from an anterior view. All movements were clearly seen less than that of the inferior rectus muscle...

BACKGROUND: A traumatic wound dehiscence can occur many years after surgery in 2-6% of all keratoplasties. Intraocular tissue prolapse can lead to severe visual loss. Deep anterior lamellar keratoplasty (DALK) leads to higher wound stability because of the intact Descemet membrane. We report a case of a novel management of wound dehiscence following DALK. METHODS: A 59-year-old patient underwent uncomplicated DALK for advanced keratoconus. Eighteen months later he experienced a traumatic wound dehiscence (globe rupture) after a fall...

The internal nasal branch of the infraorbital nerve (ION) runs down the nose and around the ala to be distributed to the nasal septum and vestibule. The aim of this study was to measure the internal nasal branch around the ala of the nose and discuss its possible relevance in clinical/surgical practice. Twelve sides from seven specimens derived from fresh frozen and embalmed Caucasian cadaveric heads were dissected. The specimens included three males and four females. The ages of the cadavers at death ranged from 65 to 84 years...
