Email: [email protected]. Abstract: In pelvic organ prolapse, anatomical defects may occur in either the anterior, posterior, or apical vaginal compartment. The apex must be evaluated correctly. Often, defects will occur in more the one compartment with apical defects contributing primarily to the descent of the anterior or posterior vaginal wall. If the vaginal apex, defined as either the cervix or vaginal cuff after total hysterectomy, is displaced downward, it is referred to as apical prolapse and must be addressed. Apical prolapse procedures may be performed via native tissue repair or with the use of mesh augmentation. Sacrospinous ligament suspension and uterosacral ligament suspension are common native tissue repairs, traditionally performed vaginally to re-support the apex. The uterosacral ligament suspension may also be performed laparoscopically. We review the pathophysiology, clinical presentation, evaluation, pre-operative considerations, surgical techniques, complications, and outcomes of these procedures.

Bigliardi Department of Veterinary Medical Sciences, University of Parma, Parma, Italy ABSTRACT: A six-year-old intact female Lagotto Romagnolo was referred with a two-day history of purulent vulvar discharge associated with fever, lethargy, polyuria, polydipsia and signs of abdominal pain. Abdominal ultra- sound revealed a grass awn foreign body in the vaginal fornix. Culture swabs obtained from the vagina revealed the presence of Staphylococcus epidermidis as the preponderant organism. Ovariohysterectomy was performed, and the presence of the grass awn was confirmed. A chronic-active vaginitis was found at histological examina- tion. The dog recovered with resolution of all clinical signs. Differential diagnoses for acute vulvar discharge in bitches should include retention of vaginal foreign bodies. To the authors’ knowledge, this is the first reported case of a grass awn foreign body in the vaginal fornix of a dog.

    An Introduction to the Anatomy of the Uterine Cervix

    Chapter 1 An introduction to the anatomy of the uterine cervix • The cervix, the lower fibromuscular portion of the uterus, measures 3-4 cm in length and 2.5 cm in diameter; however, it varies in size and shape depending on age, parity and menstrual status of the woman. • Ectocervix is the most readily visible portion of the cervix; endocervix is largely invisible and lies proximal to the external os. • Ectocervix is covered by a pink stratified squamous epithelium, consisting of multiple layers of cells and a reddish columnar epithelium consisting of a single layer of cells lines the endocervix. The intermediate and superficial cell layers of the squamous epithelium contain glycogen. • The location of squamocolumnar junction in relation to the external os varies depending upon age, menstrual status, and other factors such as pregnancy and oral contraceptive use. • Ectropion refers to the eversion of the columnar epithelium onto the ectocervix, when the cervix grows rapidly and enlarges under the influence of estrogen, after menarche and during pregnancy. • Squamous metaplasia in the cervix refers to the physiological replacement of the everted columnar epithelium on the ectocervix by a newly formed squamous epithelium from the subcolumnar reserve cells. • The region of the cervix where squamous metaplasia occurs is referred to as the transformation zone. • Identifying the transformation zone is of great importance in colposcopy, as almost all manifestations of cervical carcinogenesis occur in this zone. A thorough understanding of the anatomy and remains above the vagina (Figure 1.1). The portio physiology of the cervix is absolutely essential for vaginalis opens into the vagina through an orifice called effective colposcopic practice.
  • REPRODUCTIVE SYSTEM Vasco Dominic

    REPRODUCTIVE SYSTEM Vasco Dominic

    REPRODUCTIVE SYSTEM Vasco Dominic ORGANISATION Reproductive organs which produce gametes and hormones. Reproductive tract consisting of ducts, store and transport gametes. Accessory glands and organs that secrete fluids into the ducts of the reproductive system or into other secretory ducts. Perineal structures associated with the reproductive system, collectively known as external genitalia. The male and female systems are functionally different. In the male the gonads are the testes that secrete androgens, principally testosterone and produce a half billion sperms per day. After storage the sperm travel along a lengthy duct and mixed with secretions of the glands to form semen. In the female the gonads are the ovaries which produce only one mature gamete per month. The oocyte travels via a short duct into the muscular uterus. THE MALE REPRODUCTIVE SYSTEM TESTES Each has the shape of a flattened egg rougly 5cm long, 3cm wide and 2.5 cms thick and weighs 10-15 gms. They hang within the scrotum. During development the testes form inside the body cavity adjacent to the kidneys. As the foetus grows they move inferiorly and anteriorly towards the anterior abdominal wall. The gubernaculum testis is a cord of connective tissue and muscle fibers that extend from the inferior part of each testis to the posterior wall of a small, inferior pocket of the peritoneum. As growth proceeds the gubernacula do not elongate and the testes are held in position. During the seventh developmental month: growth continues at a rapid pace, circulating hormones stimulate contraction of the gubernaculum testis. Over this period the testes move through the abdominal musculature accompanied by small pockets of the peritoneal cavity.

  • And Immunoglobulin a in the Urogenital Tract of the Male Rodent

    And Immunoglobulin a in the Urogenital Tract of the Male Rodent

    Immunohistochemical localization of secretory component and immunoglobulin A in the urogenital tract of the male rodent M. B. Parr and E. L. Parr Southern Illinois University, School of Medicine, Department of Anatomy, Carbondale, IL 62901, U.S.A. Summary. The mucosal immune system in the male rodent urogenital tract was studied by localizing secretory component (sc) in the rat and immunoglobulin A (IgA) in both rat and mouse by immunofluorescence. In the rat, bright labelling of sc was observed at several sites, including the ejaculatory ducts, excretory ducts of several accessory glands, and urethral glands in the pelvic and bulbous portions of the urethra. Pale labelling of sc was detected in epithelial cells of the ventral prostate gland. Plasma cells containing IgA were only observed in the urethral gland in the bulbous portion of the urethra in rats and mice. These results suggest that IgA may be transported into the urogenital tract of the male rat primarily at sites distal to the production of seminal fluid and spermatozoa. While locally synthesized IgA may be available in the bulbous urethra, it appears that serum may be the main source of IgA for transport into the rat urogenital tract at the other sites where its receptor, sc, was demonstrated. Keywords: secretory component; mucosal immunity; immunoglobulin A; male urogenital tract; rat Introduction The occurrence and possible functions of a mucosal immune system in the male urogenital tract are not well understood and have thus far been studied mainly in man. Immunoglobulins A (IgA) and G (IgG) have been detected in the seminal fluids of normal men (Chodirker & Tornasi, 1963; Herrmann & Hermann, 1969; Uehling, 1971; Rumke, 1974; Tauber et ai, 1975), secretory IgA (slgA) with anti-sperm activity has been found in the genital tracts of some men after vasectomy (Witkin et al, 1983), and IgA or slgA sperm agglutinins have been reported in the seminal plasma of men with autoimmunity to spermatozoa (Friberg, 1974; Husted & Hjort, 1975; Witkin et al, 1981; Bronson et al, 1984).
