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. -
Slipping Rib Syndrome
Slipping Rib Syndrome Jackie Dozier, BS Edited by Lisa E McMahon, MD FACS FAAP David M Notrica, MD FACS FAAP Case Presentation AA is a 12 year old female who presented with a 7 month history of right-sided chest/rib pain. She states that the pain was not preceded by trauma and she had never experienced pain like this before. She has been seen in the past by her pediatrician, chiropractor, and sports medicine physician for her pain. In May 2012, she was seen in the ER after having manipulations done on her ribs by a sports medicine physician. Pain at that time was constant throughout the day and kept her from sleeping. However, it was relieved with hydrocodone/acetaminophen in the ER. Case Presentation Over the following months, the pain became progressively worse and then constant. She also developed shortness of breath. She is a swimmer and says she has had difficulty practicing due to the pain and SOB. AA was seen by a pediatric surgeon and scheduled for an interventional pain management service consult for a test injection. Following good temporary relief by local injection, she was scheduled costal cartilage removal to treat her pain. What is Slipping Rib Syndrome? •Slipping Rib Syndrome (SRS) is caused by hypermobility of the anterior ends of the false rib costal cartilages, which leads to slipping of the affected rib under the superior adjacent rib. •SRS an lead to irritation of the intercostal nerve or strain of the muscles surrounding the rib. •SRS is often misdiagnosed and can lead to months or years of unresolved abdominal and/or thoracic pain. -

Carcinomatous Cirrhosis of the Liver with Sarcomatosis of the Peritoneum 1
CARCINOMATOUS CIRRHOSIS OF THE LIVER WITH SARCOMATOSIS OF THE PERITONEUM 1 S. SANES, M.D., AND K. TERPLAN, M.D. (From tile Pathological Laboratory of the Buffalo General Hospital and School of Medicine, University of Buffalo) The following case is reported because of the occurrence of two different types of malignant neoplasm with typical portal cirrhosis of the liver. That a pathogenetic relationship exists between Laennec's cirrhosis and primary carcinoma of the liver is generally recognized. Whether the association of a peritoneal sarcoma with the cirrhosis in this case was more than a coincidence seemed an interesting point for discussion. REPORT OF CASE E. G., 11 white Italian male fifty-seven years old, was admitted to the Buffalo General Hospital on the service of Drs. N. G. Russell and A. H. Aaron, Nov. 25, 1934. He died Nov. 29, 1934. All his adult life he had partaken of large amounts of wine and whiskey daily. At the age of seventeen years he had suffered an attack of jaundice of several weeks' duration. The patient first began to lose weight and strength in 1932 and noticed that his skin was becoming dark. In March 1934 he complained of cramp-like abdominal pain, diarrhea, and bloating. The stools were watery. There was no nausea or vomiting. Upon hos pitalization, April 9, 1934, physical examination revealed that the pupils reacted to light and accommodation. The chest was emphysematous; breath sounds were diminished in both bases. The heart was regular; a systolic murmur was heard. The blood pressure was 118/70. The liver and spleen were palpable three finger breadths below the costal margin. -

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. -

Detailed and Applied Anatomy for Improved Rectal Cancer Treatment
REVIEW ARTICLE Annals of Gastroenterology (2019) 32, 1-10 Detailed and applied anatomy for improved rectal cancer treatment Τaxiarchis Κonstantinos Νikolouzakisa, Theodoros Mariolis-Sapsakosb, Chariklia Triantopoulouc, Eelco De Breed, Evaghelos Xynose, Emmanuel Chrysosf, John Tsiaoussisa Medical School of Heraklion, University of Crete; National and Kapodistrian University of Athens, Agioi Anargyroi General and Oncologic Hospital of Kifisia, Athens; Konstantopouleio General Hospital, Athens; Medical School of Crete University Hospital, Heraklion, Crete; Creta Interclinic, Heraklion, Crete; University Hospital of Heraklion, Crete, Greece Abstract Rectal anatomy is one of the most challenging concepts of visceral anatomy, even though currently there are more than 23,000 papers indexed in PubMed regarding this topic. Nonetheless, even though there is a plethora of information meant to assist clinicians to achieve a better practice, there is no universal understanding of its complexity. This in turn increases the morbidity rates due to iatrogenic causes, as mistakes that could be avoided are repeated. For this reason, this review attempts to gather current knowledge regarding the detailed anatomy of the rectum and to organize and present it in a manner that focuses on its clinical implications, not only for the colorectal surgeon, but most importantly for all colorectal cancer-related specialties.

The Formation of Peritoneal Adhesions
THE FORMATION OF PERITONEAL ADHESIONS Christian DellaCorte, Ph.D., C.M.T. The increased incidence of postoperative adhesions and their complications has focused attention on trying to understand the adhesion, adhesion formation, clinical consequences, and prevention of adhesion formation. Adhesions are highly differentiated, formed through an intricate process involving a complex organ, the peritoneum, whose surface lining is the key site in adhesion formation. The peritoneum, a serous membrane, serves a protective function for the contents of the abdominal cavity. Homeostasis is maintained by allowing exchange of molecules and production of peritoneal fluid. This provides an environment for optimal function of intra-abdominal organs. Forms of trauma to the peritoneum (i.e., mechanical, thermal, chemical, infectious, surgical, and/or ischemic) can result in the formation of peritoneal adhesions. In 1919, it was shown that peritoneal healing differed from that of skin. When the peritoneal membrane is traumatized, a dynamic response results that produces a series of steps toward rapid regeneration in approximately five to seven days of the injured peritoneum via re-epithelialization, irrespective of the size of injury. Microscopic studies showed the new peritoneal cells are derived from mesodermal cells of the underlying granulation tissue, multipotent mesenchymal cells that are able to take the form of fibroblasts or mesothelial cells. When a defect is made in the parietal peritoneum the entire surface becomes simultaneously epithelialized, differing from the gradual epidermalization from the borders as is found in skin wounds. Multiplication and migration of mesothelial cells from the margins of the wound may play a small part in the regenerative process, but it does not play a major role.
