Surface Anatomy and Subcutaneous Adipose Tissue Features in the Analysis of the Patterson- Gimlin Film Hominid The RELICT HOMINOID INQUIRY 2:1-21 (2013) Research Article SURFACE ANATOMY AND SUBCUTANEOUS ADIPOSE TISSUE FEATURES IN THE ANALYSIS OF THE PATTERSON- GIMLIN FILM HOMINID Bill Munns1*, Jeff Meldrum2 1Blue Jay, CA 92317 2Department of Biological Sciences, Idaho State University, 921 S. 8th Ave, Pocatello, ID 83209 ABSTRACT. The anatomical form of the Patterson-Gimlin film (PGF) hominid has been debated for many years, in in terms of musculoskeletal anatomy (if it is biologically real), or costume material flaws (if it is a hoax). What has been neglected however, are comparisons and contrasts of equivalent surface anatomy and subcutaneous adipose features of real human and great ape bodies. Many presumed anomalies seen in the appearance of the film subject have been uncritically attributed to artifacts of a fabricated costume. It has been asserted that these attributes are inconsistent with real musculoskeletal anatomy. An examination of normal human and great ape surface anatomy reveals that the PGF hominid’s anatomical features are, in fact, found in the superficial tissues of the human body that is aged, lacks superficial physical or athletic tone, or has not been altered by either surgical procedures or digital enhancement (“photoshopped”). The presence of equivalent surface anatomy features in the hominid body that are consistent with observed traits of the PGF hominid nullifies previous claims that such traits of necessity indicate a costume. Rather they are consistent with the conclusion that the PGF hominid indeed represents a novel primate species.

The second line of reasoning tries to explain the subject’s The best known images offered as evidence of appearance in relation to a fabricated fur suit, the existence of sasquatch, a.k.a.

The following bony prominences can usually be palpated in the living subject (corresponding vertebral levels are given in brackets): •◊◊superior angle of the scapula (T2); •◊◊upper border of the manubrium sterni, the suprasternal notch (T2/3); •◊◊spine of the scapula (T3); •◊◊sternal angle (of Louis) — the transverse ridge at the manubrio-sternal junction (T4/5); •◊◊inferior angle of scapula (T8); •◊◊xiphisternal joint (T9); •◊◊lowest part of costal margin—10th rib (the subcostal line passes through L3). Note from Fig. 1 that the manubrium corresponds to the 3rd and 4th thoracic vertebrae and overlies the aortic arch, and that the sternum corre- sponds to the 5th to 8th vertebrae and neatly overlies the heart. Since the 1st and 12th ribs are difficult to feel, the ribs should be enu- merated from the 2nd costal cartilage, which articulates with the sternum at the angle of Louis. The spinous processes of all the thoracic vertebrae can be palpated in the midline posteriorly, but it should be remembered that the first spinous process that can be felt is that of C7 (the vertebra prominens). The position of the nipple varies considerably in the female, but in the male it usually lies in the 4th intercostal space about 4in (10cm) from the midline.

  • Six Steps to the “Perfect” Lip Deborah S
    September 2012 1081 Volume 11 • Issue 9 Copyright © 2012 ORIGINAL ARTICLES Journal of Drugs in Dermatology SPECIAL TOPIC Six Steps to the “Perfect” Lip Deborah S. Sarnoff MD FAAD FACPa and Robert H. Gotkin MD FACSb,c aRonald O. Perelman Department of Dermatology, New York University School of Medicine, New York, NY bLenox Hill Hospital—Manhattan Eye, Ear & Throat Institute, New York, NY cNorth Shore—LIJ Health Systems, Manhasset, NY ABSTRACT Full lips have always been associated with youth and beauty. Because of this, lip enhancement is one of the most frequently re- quested procedures in a cosmetic practice. For novice injectors, we recommend hyaluronic acid (HA) as the filler of choice. There is no skin test required; it is an easily obtainable, “off-the-shelf” product that is natural feeling when skillfully implanted in the soft tissues. Hyaluronic acid is easily reversible with hyaluronidase and, therefore, has an excellent safety profile. While Restylane® is the only FDA-approved HA filler with a specific indication for lip augmentation, one can use the following HA products off-label: Juvéderm® Ultra, Juvéderm Ultra Plus, Juvéderm Ultra XC, Juvéderm Ultra PLUS XC, Restylane-L®, Perlane®, Perlane-L®, and Belotero®. We present our six steps to achieve aesthetically pleasing augmented lips. While there is no single prescription for a “perfect” lip, nor a “one size fits all” approach for lip augmentation, these 6 steps can be used as a basic template for achieving a natural look. For more comprehensive, global perioral rejuvenation, our 6-step technique can be combined with the injection of neuromodulating agents and fractional laser skin resurfacing during the same treatment session.

You examine the patient and find her to be alert but pale and sweaty, with breathing that is rapid and shallow. You see that she has distension of her right internal jugular vein visible to the jaw and neck. Her trachea is deviated 3 cm to the right of midline. She has tender contu- sions on her left anterior chest wall with minimal active bleeding over one of the ribs. During the brief period of your examination, the patient exhibits more respiratory distress, and her blood pressure begins to drop. You urgently insert a large-gauge needle into her left hemitho- rax and withdraw 20 cc of air. This results in immediate improvement in the patient’s breath- ing and blood pressure. Why does the patient have a distended internal jugular vein on the right side of her neck? Could this be related to a rapid drop in blood pressure? What is the clinical situation of this patient?

  • Anatomic Imaging of Gluteal Perforator Flaps Without Ionizing Radiation: Seeing Is Believing with Magnetic Resonance Angiography
    Anatomic Imaging of Gluteal Perforator Flaps without Ionizing Radiation: Seeing Is Believing with Magnetic Resonance Angiography Julie V. Vasile, M.D.,1 Tiffany Newman, M.D.,2 David G. Rusch, M.D.,4 David T. Greenspun, M.D.,5 Robert J. Allen, M.D.,1 Martin Prince, M.D.,3 and Joshua L. Levine, M.D.1 ABSTRACT Preoperative imaging is essential for abdominal perforator flap breast reconstruc- tion because it allows for preoperative perforator selection, resulting in improved operative efficiency and flap design. The benefits of visualizing the vasculature preoperatively also extend to gluteal artery perforator flaps. Initially, our practice used computed tomography angiography (CTA) to image the gluteal vessels. However, with advances in magnetic resonance imaging angiography (MRA), perforating vessels of 1-mm diameter can reliably be visualized without exposing patients to ionizing radiation or iodinated intravenous contrast. In our original MRA protocol to image abdominal flaps, we found the accuracy of MRA compared favorably with CTA. With our increased experience with MRA, we decided to use MRA to image gluteal flaps. Technical changes were made to the MRA protocol to improve image quality and extend the field of view. Using our new MRA protocol, we can image the vasculature of the buttock, abdomen, and upper thigh in one study. We have found that the spatial resolution of MRA is sufficient to accurately map gluteal perforating vessels, as well as provide information on vessel caliber and course. This article details our experience with preoperative imaging for gluteal perforator flap breast reconstruction. KEYWORDS: Gluteal artery perforator flap, superior gluteal artery perforator flap, inferior gluteal artery perforator flap, magnetic resonance imaging angiography, preoperative imaging The ability to dissect a perforating vessel of appearance and feel can be created from a patient’s own adequate caliber to provide blood flow to a flap of skin tissue while minimizing injury to the underlying muscle and subcutaneous fat without sacrificing the muscle has at the donor site.

Obtaining a beautiful smile is always the main objective of any aesthetic dental treatment. The gummy smile is a condition characterised by an excessive display of maxillary gingivae during smiling. One cause of excessive gingival display is the muscular capacity to raise the upper lip higher than average. Several surgical procedures have been reported to improve the condition, but surgery always involves risk and is costly. Botulinum toxin type A (BTX-A) (Botox; Allergan, Irvine, Calif) has been studied since the late 1970s for the treatment of several conditions associated with excessive muscle contraction or pain.Injection with BTX-A at preselected sites is a novel, cosmetically effective, minimally invasive alternative for the temporary improvement of gummy smiles caused by hyperfunctional upper lip elevator muscles. Keywords: Botulinum toxin, excessive gingival display, unesthetic smiles,facial muscles. I. Introduction Smile is one of the most important expression contributing to facial attractiveness. An attractive or pleasing smile enhances the acceptance of individual in the society by improving interpersonal relationships.[1] A smile is considered the universal friendly greeting in all cultures.
