Hamed M. El Darawany1 · Mahmoud E. Al Damhogy2 · Mohamed S. Kandil2 · Mohamed E. ELkordi2 · Salah A. Nagla3 · Mohamed R. Taha3 Received: 9 March 2019 / Accepted: 29 April 2019 / Published online: 10 May 2019 © Springer Nature B.V. 2019 Abstract Objectives To report our experience in starting the correction of penile torsion, whatever its degree (moderate or severe) with one or more simple procedures either separately or complementary in the same session. Patients and methods Between 2013 and 2018, 62 patients who have signifcant isolated penile torsion (> 45°) were involved in this study. Those patients were subjected to either simple degloving with skin reposition, degloving with skin overcor‑ rection and/or dartos fap procedures. Those procedures were performed either separately or complementarily. All patients were examined postoperatively after 7 days and followed up at 3, 6, and 9 months postoperatively. Results 37 out of 62 patients had a moderate degree (45–90) of penile torsion; 21 of them were corrected using skin deglov‑ ing–reattachment technique, 11 patients were corrected by degloving with skin overcorrection, and in the remaining 4 patients dartos fap technique was used for correction. In 25/62 patients who had severe degree (> 90°) of torsion; 9 patients were managed by degloving with skin overcorrection, while in 13 patients the procedure was shifted to dartos fap technique, and the remaining 3 patients, 2 of whom had 180° torsion, were managed by dartos fap with added skin overcorrection. Conclusion Performing degloving and skin reattachment with or without skin overcorrection procedure and dartos fap procedure either separately or complementarily in the same patient whatever the degree of torsion (moderate or severe) is associated with good results and can protect some patients from exposure to more difcult and extensive procedures as corporopexy and corporeal plication.

Buncamper Copy Editor: Cai-Hong Wang Production Editor: Jing Yu Abstract Penile skin grafting is an effective technique for managing skin deficiency resulting from a variety of causes. A thorough understanding of penile anatomy and the pathophysiology of the underlying condition being treated are essential. We provide an overview of penile anatomy as well as the pathophysiology of conditions that may lead to penile skin deficiency, as a result of either the underlying condition or its management. The conditions discussed include lichen sclerosus, buried penis, hidradenitis suppurativa, lymphedema, necrotizing fasciitis, cancer, and trauma. We also discuss surgical technique for penile skin grafting with an emphasis on technical considerations unique to the penis.

Under the auspices of the World Association of Veterinary Anatomists (W.A.V.A.), the International Committee on Veterinary Anatomical Nomenclature (I.C.V.A.N.) appointed in Giessen, 1965, a Subcommittee on Histology and Embryology which started a working relation with the Subcommittee on Histology of the former International Anatomical Nomenclature Committee. In Mexico City, 1971, this Subcommittee presented a document entitled Nomina Histologica Veterinaria: A Working Draft as a basis for the continued work of the newly-appointed Subcommittee on Histological Nomenclature. This resulted in the editing of the Nomina Histologica Veterinaria: A Working Draft II (Toulouse, 1974), followed by preparations for publication of a Nomina Histologica Veterinaria.

    BOSNIAN JOURNAL OF BASIC MEDICAL SCIENCES REVIEW ARTICLE WWW.BJBMS.ORG A plea for an extension of the anatomical nomenclature: Organ systems Vladimir Musil1*, Alzbeta Blankova2, Vlasta Dvorakova3, Radovan Turyna2,4, Vaclav Baca3 1Centre of Scientific Information, Third Faculty of Medicine, Charles University, Prague, Czech Republic,2 Department of Anatomy, Second Faculty of Medicine, Charles University, Prague, Czech Republic, 3Department of Health Care Studies, College of Polytechnics Jihlava, Jihlava, Czech Republic, 4Institute for the Care of Mother and Child, Prague, Czech Republic ABSTRACT This article is the third part of a series aimed at correcting and extending the anatomical nomenclature. Communication in clinical medicine as well as in medical education is extensively composed of anatomical, histological, and embryological terms. Thus, to avoid any confusion, it is essential to have a concise, exact, perfect and correct anatomical nomenclature. The Terminologia Anatomica (TA) was published 20 years ago and during this period several revisions have been made. Nevertheless, some important anatomical structures are still not included in the nomenclature. Here we list a collection of 156 defined and explained technical terms related to the anatomical structures of the human body focusing on the digestive, respiratory, urinary and genital systems. These terms are set for discussion to be added into the new version of the TA.

Abstract: Purpose: Our purpose is to study the use of buck’s fascia and dartos fascia to reinforce urethral suture line in hypospadias surgery to decrease the fistula rate and post op complications. Introduction:-The most common congenital penile anomaly in children is hypospadias (68./.) followed by chordee (8.6./.) and hypospadias with chordee (5./.). Fistula and glans disruption are still the most frequent complications of hypospadias surgery.Neourethral coverage is a mandatory step in this challenging surgery; it reduces the rate of fistula. This coverage can be bucks fascia, dartos fascia& tunica vaginalis, Glue, etc.

MATERIALS AND Twelve hypospadias presenting at older age (8-20 years) were studied with 1.5-T magnetic METHODS resonance imaging scanner and a 3-inch surface coil. Precontrast and postcontrast images were acquired using fast-spin echo sequences in sagittal, coronal, and transverse planes. The findings were processed in Volume Share 4.5, version Workstation, of General Electric Healthcare. Anatomic findings were verified during surgery. With imaging and surgical findings, a 3-dimensional conceptual diagram of surgical anatomy was created. RESULTS Distinct layers of the skin, dartos fascia, Buck fascia, tunica albuginea, glans urothelium, lamina propria of glans, and corpus spongiosum were delineated with their spatial relationship. Axial pattern vessels of the dartos and its anastomosis with branches of dorsal penile vessels at the coronal sulcus, perforators along the corpus spongiosum, subglanular extension of the fascia, and intraglanular branches of the dorsal penile artery forming an arcade were visualized. CONCLUSION Dorsomedial and dorsolateral axial pattern vessels are present in penile dartos with relative avascularity at dorsal midline in most cases. Subglanular extension of Buck fascia fused with the basal lamina propria of glans forms a barrier between the tip of corpora and the intraglanular arcade of vessels.
