    Item does not contain fulltextINTRODUCTION AND HYPOTHESIS: The objective of this work was to collect and summarize a detailed historical review of the surgical treatment of pelvic organ prolapse (POP) in which we specifically focused on the anterior compartment. METHODS: A literature search in English, Dutch, and German was carried out using the keywords pelvic organ prolapse, anterior colporrhaphy, cystocele, and interposition operations in several databases (e.g., PubMed and HathiTrust Digital Library). Other relevant journal and textbook articles were found by retrieving references cited in previous articles and textbooks. RESULTS: Probably the first explanation of the treatment of POP dates from 1500 B.C. The Egyptians gave a description to "falling of the womb" in the Kahun Papyrus. More than a millennium later, Euryphon, a contemporary of Hippocrates (400 B.C.) described some interesting therapeutic options, from succussion (turning a women upside down for several minutes) to irrigating the displaced uterus with wine. A wide range of techniques has been attempted to repair the prolapsing anterior vaginal wall. By 1866, Sim had already performed a series of operations very similar to a modern anterior repair. The first reviews about the abdominal approach to correcting a cystocele were in 1890. The first description of using mesh to cystoceles was the use of tantalum mesh in 1955. In 1970, the first report of collagen mesh in urogynecology was described. Nowadays, robot-assisted surgery and cell-based tissue engineering are the latest interventions. CONCLUSION: Many surgeons have tried to find the ideal surgical therapy for anterior compartment prolapse, but to date, this has not been achieved

    GNAI3: Another Candidate Gene to Screen in Persons with Ocular Albinism

    Ocular albinism type 1 (OA), caused by mutations in the OA1 gene, encodes a G-protein coupled receptor, OA1, localized in melanosomal membranes of the retinal pigment epithelium (RPE). This disorder is characterized by both RPE macro-melanosomes and abnormal decussation of ganglion cell axons at the brain's optic chiasm. We demonstrated previously that Oa1 specifically activates Gαi3, which also signals in the Oa1 transduction pathway that regulates melanosomal biogenesis. In this study, we screened the human Gαi3 gene, GNAI3, in DNA samples from 26 patients who had all clinical characteristics of OA but in whom a specific mutation in the OA1 gene had not been found, and in 6 normal control individuals. Using the Agilent HaloPlex Target Enrichment System and next-generation sequencing (NGS) on the Illumina MiSeq platform, we identified 518 variants after rigorous filtering. Many of these variants were corroborated by Sanger sequencing. Overall, 98.8% coverage of the GNAI3 gene was obtained by the HaloPlex amplicons. Of all variants, 6 non-synonymous and 3 synonymous were in exons, 41 in a non-coding exon embedded in the 3' untranslated region (UTR), 6 in the 5' UTR, and 462 in introns. These variants included novel SNVs, insertions, deletions, and a frameshift mutation. All were found in at least one patient but none in control samples. Using computational methods, we modeled the GNAI3 protein and its non-synonymous exonic mutations and determined that several of these may be the cause of disease in the patients studied. Thus, we have identified GNAI3 as a second gene possibly responsible for X-linked ocular albinism
