Hysterectomy: Let's Step Up the Ladder of Evidence to Look Over the Horizon

2022

Hysterectomy is one of the most common non-obstetric gynecological surgical procedures carried out in Western countries [...]

Internal limiting membrane peeling versus no peeling during primary vitrectomy for rhegmatogenous retinal detachment: A systematic review and meta-an…

2018

Background Internal limiting membrane (ILM) peeling during primary vitrectomy for rhegmatogenous retinal detachment (RRD) prevents the formation of postoperative macular epiretinal membrane (ERM). However, studies that compared vitrectomy with and without ILM peeling for RRD, have reported controversial outcomes. Objective To assess the efficacy of ILM peeling versus non-ILM peeling during vitrectomy for RRD by a systematic review and meta-analysis of published studies. Methods PubMed, Medline, Web of Science, Embase databases, and the Cochrane Library were searched up to April 2018 to identify studies that compared primary vitrectomy with and without ILM peeling for RRD with at least six m…

On the role of internationalization of firm-level corporate governance: The case of audit committees

2022

Research Question/IssueMotivated by the agency theory and the findings of linguistic studies, we analyze the association between the internationalization of a firm's audit committee and its corporate governance.Research Findings/InsightsBased on data from 2159 publicly traded European firms from 15 countries for the period 2000–2018, we find that firms with foreign directors on their audit committees are associated with lower financial reporting quality. The association is mitigated by stronger country-level investor protection and a higher similarity among intra-committee languages. We further find that foreign directors on the audit committee are related to stock prices being less informa…

Uterine rejection after allogeneic uterus transplantation in the rat is effectively suppressed by tacrolimus

2013

Objective To evaluate the effects of the immunosuppressant tacrolimus on rejection of a transplanted uterus and on uterine expression of markers of inflammation and implantation. Design Experimental study. Setting University laboratory. Animal(s) Female rats. Intervention(s) Uteri from brown Norway rats were transplanted to Lewis rats, receiving either tacrolimus or no treatment. Sham groups underwent either hemihysterectomy or tacrolimus treatment. Main Outcome Measure(s) Gross morphology, histology, density of T-lymphocytes by immunohistochemistry, and mRNA levels of interleukin (IL)-1α, leukemia inhibitory factor (LIF), galectin-1, CD200, IL-15, interferon-inducible protein-10 (IP-10), a…

Uterus Transplantation

2018

Uterus transplantation (UTx) has been successfully introduced as a treatment option for women with absolute uterine factor infertility (AUFI). AUFI representing approximately 3% to 5% of the female general population is linked to either congenital uterine agenesis (Mayer-Rokitansky-Küster-Hauser syndrome), major congenital uterine malformation (hypoplastic uterus, fraction of bicornuate/unicornuate uterus), a surgically absent uterus, or an acquired condition (intrauterine adhesions, leiomyoma) linked to uterine malfunction that causes implantation failure or defect placentation. The world's first clinical uterus transplant was performed in 2000. However, a hysterectomy became necessary sho…

Preclinical report on allogeneic uterus transplantation in non-human primates

2013

Study question Is it possible to perform allogeneic uterus transplantation (UTx) with a donation from a live donor in a non-human primate species and what immunosuppression is needed to prevent rejection? Summary answer Allogeneic UTx in the baboon is a donor- and recipient-safe surgical procedure; immunosuppression with induction therapy and a triple protocol should be used. What is known already UTx may become a treatment for absolute uterine factor infertility. Autologous UTx models have been developed in non-human primates with reports on long-term survival of the uterine grafts. STUDY DESIGN, SIZEAND DURATION: This experimental study included 18 female baboons as uterus donors and 18 f…

Massive Adenomyose bei einer Patientin mit Uterus septus completus

2006

Septate uterus is a malformation caused by the defective resorption of the Mullerian ducts. It may be incomplete, or -- less frequently -- complete. We present a case of a uterus septus completus with special emphasis on the endometrial changes. We describe a 46-year-old female patient (nullipara) with a known uterus septus suffering from hypermenorrhea. Sonography demonstrated a massively enlarged uterus with several nodes. Hysterectomy was performed and tissue specimens were routinely processed. Macroscopical examination revealed a 1 230 g-weight uterus septus completus. In particular, the myometrium was enlarged and exhibited a cystic cut surface with several nodes measuring up to 4.5 cm…

Morphometrische Untersuchungen an Darminterponaten nach totaler Gastrektomie

1982

Im Tierexperiment wurden nach totaler Gastrektomie die Bildung eines Ersatzmagens mit verschiedenen Darminterponaten sowie der Oesophago-Jejunostomie mit Roux-Y-Anastomose durchgefuhrt. Bei der Relaparotomie nach 3monatiger postoperativer Uberlebenszeit wurden die Interponate an ausgewahlten Stellen morphometrisch untersucht. Als deutlichste Veranderung fiel bei allen Dunndarmersatzmagen eine starke muskulare Wandhypertrophie auf, die vor allem die Ringmuskulatur betraf. Beim Colonersatzmagen, der physiologisch eine dickere Wandmuskulatur besitzt, war die Hypertrophie sehr viel geringer. Als pathogenetischer Faktor dieser Veranderung gilt die Volumenbelastung, der der Ersatzmagen an dieser …

Akute Retinanekrose

1997

Einfuhrung: Da Studien zur Behandlung der akuten Retinanekrose (ARN) inzidenzbedingt kleine Fallzahlen haben und alle verfugbaren Daten zusammengetragen werden mussen, berichten wir uber unsere operativen Ergebnisse bei Netzhautablosungen durch ARN. Patienten und Methode: Nachuntersucht wurden 13 Augen von 13 Patienten mit Netzhautablosung bei ARN, die konsekutiv in unserer Klinik zwischen Januar 1988 und Juni 1995 operiert wurden. Das Patientenalter betrug 25 – 56 Jahre. Vier Patienten waren HIV-positiv, 9 Patienten immunkompetent. Bei 5 Patienten, die primar mit segmentalen Plomben versorgt worden waren, wurde eine Vitrektomie mit Membrane peeling, Silikonolendotamponade und Endolaserbeha…
