Pelvic organ prolapse repair using the Uphold (TM) Vaginal Support System : a 1-year multicenter study

The objective was to assess safety and clinical outcomes in women operated on using the Uphold (TM) Lite Vaginal Support System. We carried out a 1-year, multicenter, prospective, single cohort study of 207 women with symptomatic Pelvic Organ Prolapse Quantification (POP-Q) stage aeyen2 apical pelvic organ prolapse, with or without concomitant anterior vaginal wall prolapse. Safety data were collected using a standardized questionnaire. Anatomical outcome was assessed by the POP-Q and subjective outcomes by the Pelvic Floor Distress Inventory after 2 months and 1 year using a one-way repeated measures analysis of variance. Pain was evaluated using a visual analog scale. The overall rate of serious complications was 4.3 % (9 out of 207 patients), including 3 patients with bladder perforations, 1 with bleeding > 1,000 ml, 2 who had undergone re-operations with complete mesh removal because of pain, and 3 surgical interventions during follow-up because of mesh exposure. POP-Q stage aecurrency sign1 after 1 year was 94 % and subjective symptom relief was reported by 91 % of patients (p <0.001). Pain after 2 months and 1 year was 60 % lower compared with the preoperative mean (p <0.001). Minor complications occurred in 20 women (9.7 %) and were dominated by lower urinary tract dysfunction. No predisposing risk factors for complications were found. The Uphold (TM) Lite procedure in women with apical pelvic organ prolapse provided satisfactory restoration of vaginal topography and symptom relief. However, serious complication rates were largely comparable with those of other transvaginal mesh kits.Peer reviewe

Conduct of labor and rupture of the sphincter ani.

OBJECTIVE: To determine whether the conduct of the second stage of labor and delivery technique influences the incidence of rupture of the anal sphincter. MATERIAL AND METHOD: A total of 1072 primipara delivered vaginally at term at Rigshospitalet in 1998. A questionnaire on prenatal risk factors, conduct of the second stage of labor, and delivery technique was completed by the attending midwife immediately after delivery in 90 cases with rupture of the sphincter and in two subsequent controls (n = 164), matched by use of vacuum extractor and episiotomy. RESULTS: Partial or total sphincter rupture was found in 8.4% of primipara who delivered vaginally, in 20.9% of those delivered by vacuum extraction, and in 6.4% of those with episiotomy only. The prenatal risk factors--maternal age, birth weight, shoulder dystocia, and edema of the perineum were found to have a statistically significant effect on the incidence of rupture of the sphincter ani. In non-instrumental vaginal deliveries easing of the perineum over the caput as it advanced helped prevent a rupture of the anal sphincter. Vacuum extraction performed with the woman in a semi-recumbant position was associated with an increased risk of rupture of the anal sphincter, whereas attention to the perineum during extraction decreased the risk. CONCLUSIONS: The significant effect of prenatal risk factors did not explain a correlation between delivery technique and rupture of the sphincter ani. The present study indicates that a reduction in the incidence of sphincter rupture may be accomplished by improved obstetric care: fewer vacuum extractions and improved delivery technique

Review - Chromosome 13 dementia syndromes as models of neurodegeneration

Two hereditary conditions, familial British dementia (FBD) and familial Danish dementia (FDD), are associated with amyloid deposition in the central nervous system and neurodegeneration. The two amyloid proteins, A Bri and ADan, are degradation products of the same precursor molecule BriPP bearing different genetic defects, namely a Stop-to-Arg mutation in FBD and a ten-nucleotide duplication-insertion immediately before the stop codon in FDD. Both de novo created amyloid peptides have the same length (34 amino acids) and the same post-translational modification (pyroglutamate) at their N-terminus. Neurofibrillary tangles containing the classical paired helical filaments as well as neuritic components in many, instances co-localize with the amyloid deposits. In both disorders, the pattern of hyperphosphorylated tau immunoreactivity is almost indistinguishable from that seen in Alzheimer's disease. These issues argue for the primary importance of the amyloid deposits in the mechanism(s) of neuronal cell loss. We propose FBD and FDD, the chromosome 13 dementia syndromes, as models to study the molecular basis of neurofibrillary degeneration, cell death and amyloid formation in the brain
