The goal of treatment is an early female gender assignment and feminizing reconstruction of the perineum. KEY WORDS: Aphallia, Penile agenesis, Ambiguous genitalia Penile agenesis (PA) is an extremely rare developmental the scrotal folds which were preserved for subsequent anomaly with the reported incidence of 1 in 30 million genital reconstruction. births[1]. PA is believed to result from either the absence of the genital tubercle, or its failure to develop.[2] Several DISCUSSION investigators claim the absence of corpora cavernosa and corpora spongiosum as a prerequisite for the diagnosis of The earliest case report of aphallia was by Imminger in penile agenesis.[3] Except for the reported XX-XY mosaic, 1853[2] since then only 75 cases have been reported in the patients have 46 XY karyotypes.[4] More than half of these literature[6].

Urinary System Intermediate Mesoderm
Urinary System Intermediate mesoderm lateral mesoderm: somite ectoderm neural NOTE: Intermediate mesoderm splanchnic groove somatic is situated between somites and lateral mesoderm (somatic and splanchnic mesoderm bordering the coelom). All mesoderm is derived from the primary mesen- intermediate mesoderm endoderm chyme that migrated through the notochord coelom (becomes urogenital ridge) primitive streak. Intermediate mesoderm (plus adjacent mesothelium lining the coelom) forms a urogenital ridge, which consists of a laterally-positioned nephrogenic cord (that forms kidneys & ureter) and a medially-positioned gonadal ridge (for ovary/testis & female/male genital tract formation). Thus urinary & genital systems have a common embryonic origin; also, they share common ducts. NOTE: Urine production essentially requires an increased capillary surface area (glomeruli), epithelial tubules to collect plasma filtrate and extract desirable constituents, and a duct system to convey urine away from the body. Kidneys Bilateraly, three kid- mesonephric duct neys develop from the neph- metanephros pronephros rogenic cord. They develop mesonephric tubules chronologically in cranial- mesonephros caudal sequence, and are designated pro—, meso—, Nephrogenic Cord (left) and meta—, respectively. cloaca The pronephros and mesonephros develop similarly: the nephrogenic cord undergoes seg- mentation, segments become tubules, tubules drain into a duct & eventually tubules disintegrate. spinal ganglion 1] Pronephros—consists of (7-8) primitive tubules and a pronephric duct that grows caudally and terminates in the cloaca. The tubules soon degenerate, but the pronephric duct persists as the neural tube mesonephric duct. (The pronephros is not functional, somite except in sheep.) notochord mesonephric NOTE tubule The mesonephros is the functional kidney for fish and am- aorta phibians. The metanephros is the functional kidney body of reptiles, birds, & mammals. -

Box 8013 Baltimore, MD 21244-1850 RE: Medicare Program; Hospital Inpatient Prospective Payment Systems for Acute Care Hospitals and the Long-Term Care Hospital Prospective Payment System and Proposed Policy Changes and Fiscal Year 2020 Rates; Proposed Quality Reporting Requirements for Specific Providers; Medicare and Medicaid Promoting Interoperability Programs Proposed Requirements for Eligible Hospitals and Critical Access Hospitals Dear Ms. Verma: On behalf of the over 80,000 members of the American College of Surgeons (ACS), we appreciate the opportunity to submit comments to the Centers for Medicare & Medicaid Services’ (CMS) proposed rule, Medicare Program; Hospital Inpatient Prospective Payment Systems for Acute Care Hospitals and the Long-Term Care Hospital Prospective Payment System and Proposed Policy Changes and Fiscal Year 2020 Rates; Proposed Quality Reporting Requirements for Specific Providers; Medicare and Medicaid Promoting Interoperability Programs Proposed Requirements for Eligible Hospitals and Critical Access Hospitals, published in the Federal Register on May 3, 2019. The ACS is a scientific and educational association of surgeons founded in 1913 to improve the quality of care for patients by setting high standards for surgical education and practice. Since a large portion of surgical care is provided in the inpatient hospital setting, the College has a vested interest in CMS’ Inpatient Prospective Payment System (IPPS) and related hospital quality improvement efforts, and we believe that we can offer insight to CMS’ proposed modifications to these policies for fiscal year (FY) 2020. Our comments below are presented in the order in which they appear in the proposed rule. -

Department of Obstetrics & Gynaecology, Federal Medical centre, Bida Nigeria Abstract Background: Abnormalities of the male external genitalia and groin, a set of lesions which may be congenital or acquired, are rather obscured to many kids and their parents and Nigerian health care system has no formal program to detect them. Objectives: To identify and determine the prevalence of abnormalities of external genitalia and groin among primary school boys in Bida, Nigeria. Methods: This was a cross-sectional study of primary school male pupils in Bida. A detailed clinical examination of the external genitalia and groin was performed on them. Results: Abnormalities were detected in 240 (36.20%) of the 663 boys, with 35 (5.28%) having more than one abnormality. The three most prevalent abnormalities were penile chordee (37, 5.58%), excessive removal of penile skin (37, 5.58%) and retractile testis (34, 5.13%). The prevalence of complications of circumcision was 15.40% and included excessive residual foreskin, exces- sive removal of skin, skin bridges and meatal stenosis. -

The Approach to the Infant with Ambiguous Genitalia
334 Review Article Disorders/differences of sex development (DSDs) for primary care: the approach to the infant with ambiguous genitalia Justin A. Indyk Section of Endocrinology, Nationwide Children’s Hospital, the Ohio State University, Columbus, Ohio 43205, USA Correspondence to: Justin A. Indyk, MD, PhD. THRIVE Program, Section of Endocrinology, Nationwide Children’s Hospital, 700 Children’s Drive, Columbus, Ohio 43205, USA. Email: [email protected]. Abstract: The initial management of the neonate with ambiguous genitalia can be a very stressful and anxious time for families, as well as for the general practitioner or neonatologist. A timely approach must be sensitive and attend to the psychosocial needs of the family. In addition, it must also effectively address the diagnostic dilemma that is frequently seen in the care of patients with disorders of sex development (DSDs). One great challenge is assigning a sex of rearing, which must take into account a variety of factors including the clinical, biochemical and radiologic clues as to the etiology of the atypical genitalia (AG). However, other important aspects cannot be overlooked, and these include parental and cultural views, as well as the future outlook in terms of surgery and fertility potential. Achieving optimal outcomes requires open and transparent dialogue with the family and caregivers, and should harness the resources of a multidisciplinary team. The multiple facets of this approach are outlined in this review. Keywords: Sex; gender; genitalia; DSD; -
