1. 1. Anal fistulae - Three-dimensional endoanal ultrasound and outcomes of collagen plug treatment

   Författare :Ursula Fält; Kirurgi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; analfistel; Crohns sjukdom; kryptoglandulär fistel; kollagenplugg; komplicerad analfistel; tredmensionellt endoanalt ultraljud; analkanalens längd; analkanalens anatomi; anal fistula; Crohn s disease; cryptoglandular fistula; anal fistula plug; Complex anal fistula; three-dimensional endoanal ultrasound; anal canal length; anal canal anatomy;

   Sammanfattning : Background: The treatment of complex anal fistulae remains a therapeutic challenge. Early anal fistula plug (AFP) studies showed high success rates, while later reports demonstrated success rate of 13-100% at usual follow-up of 6-24 months. LÄS MER

3. 2. Anatomical and physiological aspects of anorectal dysfunction

   Författare :Geert Morren; Anders Mellgren; Linköpings universitet; []
   Nyckelord :Anal canal; Anal-sphincter repair; Audit; Magnetic resonance imaging; Magnetic stimulation; Latency; Pelvic floor; Sacral roots; MEDICINE; MEDICIN;

   Sammanfattning : Objective: To analyse the results of anal-sphincter repair; to examine the feasibility of motor latency measurements of the anal sphincter after magnetic sacral stimulation in healthy subjects, patients with a spinal cord injury and patients with faecal incontinence, using a new recording technique; to study, in the same 3 groups, the effects ofphasic magnetic sacral root stimulation on the anal sphincter and rectum; to describe normal, undisturbed anatomy of the anal canal and perianal structures in both men and nulliparous women using high-resolution phased array magnetic resonance imaging; to study pelvic floor movements in healthy volunteers of both sexes using a new instrument.Methods: Latencies were recorded with an intraanal, bipolar sponge electrode and an intrarectal ground electrode.

4. 3. ULTRASOUND STUDIES ON PELVIC FLOOR PHYSIOLOGY AND OBSTETRIC PERINEAL TEARS

   Författare :Ann-Kristin Örnö; Lund Obstetrik och gynekologi; []
   Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; reproduction; sexuality; Obstetrik; andrology; bladder neck descent; rectoanal inhibitory reflex; rectal sensation; Hirschsprung´s disease; Obstetrics; gynaecology; Valsalva manoeuvre; perineal tears; Pelvic floor; anal sphincter; gynekologi; andrologi; reproduktion; sexualitet;

   Sammanfattning : Repair of obstetric perineal tears is one of the most frequent procedures in surgical practice. Despite repair such tears may result in anal and urinary incontinence and prolapses of the pelvic floor, problems in need of surgical repair later in life. LÄS MER

5. 4. Sphincter injuries and anal incontinence after vaginal delivery : a clinical and physiological study

   Författare :Jan Zetterström; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :Obstetric sphincter injury; anal sphincter defect; anal incontinence; perineal body; endoanal ultrasonography; anorectal manometry; pudendal nerve terminal motor latency;

   Sammanfattning : Objective: To investigate the frequency and degree of anal incontinence after vaginal delivery in primiparous women, to determine risk factors for obstetric sphincter tears and to evaluate outcome of primary repair, to evaluate perineal body measurement (PBM) in patients with obstetric sphincter injuries, to study anal sphincter morphology and function before and after delivery, and to evaluate primiparous women who had sustained a sphincter tear or developed anal incontinence after delivery. Methods: Questionnaires regarding anal incontinence before pregnancy, at five and nine months after delivery were used. LÄS MER

7. 5. Human papillomavirus in men who have sex with men, transgender women and people living with HIV in Pakistan

   Författare :Muslima Ejaz; Karolinska Institutet; Karolinska Institutet; []
   Nyckelord :;

   Sammanfattning : Background: Anal infection with human papillomavirus (HPV) and associated anal squamous intraepithelial lesions (ASIL), are more prevalent among men who have sex with men (MSM) particularly among MSM and transgender women living with HIV The high prevalence of HIV among MSM and transgender women in Pakistan is a significant health concern and access to screening and health-seeking is often delayed due to stigmatization and discrimination. Anal Papanicolaou (Pap) screening may have utility in the identification of these lesions and is a cost- effective modality for anal cancer prevention among MSM, but no such data are available for Pakistan.
