Iatrogenic orifice transluminal endoscopic surgery (IOTES): managing uterine perforations at operative hysteroscopy

To prove safety and feasibility of an intra-abdominal endoscopic evaluation via an iatrogenic uterine perforation that occurred during operative hysteroscopy.

Laparoscopy or laparotomy? A comparison of 240 patients with early-stage endometrial cancer

This study aimed to compare the safety and efficacy of laparoscopy and laparotomy in the surgical treatment of early endometrial cancer, especially in obese women.

PPAR-gamma expression in peritoneal endometriotic lesions correlates with pain experienced by patients

Endometriosis is a significant gynecologic condition that can cause both pain and infertility and affects up to 15% of women during their reproductive years. In peritoneal endometriotic lesions, the expression of peroxisome proliferation-activated receptor gamma, a nuclear receptor with antiinflammatory and neuroprotective roles, is positively correlated with the pain reported by patients.

MicroRNAs may mediate the down-regulation of neurokinin-1 receptor in chronic bladder pain syndrome

Bladder pain syndrome (BPS) is a clinical syndrome of pelvic pain and urinary urgency-frequency in the absence of a specific cause. Investigating the expression levels of genes involved in the regulation of epithelial permeability, bladder contractility, and inflammation, we show that neurokinin (NK)1 and NK2 tachykinin receptors were significantly down-regulated in BPS patients. Tight junction proteins zona occludens-1, junctional adherins molecule -1, and occludin were similarly down-regulated, implicating increased urothelial permeability, whereas bradykinin B(1) receptor, cannabinoid receptor CB1 and muscarinic receptors M3-M5 were up-regulated. Using cell-based models, we show that prolonged exposure of NK1R to substance P caused a decrease of NK1R mRNA levels and a concomitant increase of regulatory micro(mi)RNAs miR-449b and miR-500. In the biopsies of BPS patients, the same miRNAs were significantly increased, suggesting that BPS promotes an attenuation of NK1R synthesis via activation of specific miRNAs. We confirm this hypothesis by identifying 31 differentially expressed miRNAs in BPS patients and demonstrate a direct correlation between miR-449b, miR-500, miR-328, and miR-320 and a down-regulation of NK1R mRNA and/or protein levels. Our findings further the knowledge of the molecular mechanisms of BPS, and have relevance for other clinical conditions involving the NK1 receptor.

An adjustable sling in the management of recurrent urodynamic stress incontinence after previous failed midurethral tape

The aim of this prospective study was to evaluate the feasibility and outcome of an adjustable sling system AMI in patients with recurrent urinary stress incontinence after failed suburethral sling insertion.

Suspicious axillary lymph nodes in patients with unremarkable imaging of the breast

The aim of this study was to evaluate the pathological findings and the method of tissue harvesting in those patients who have both suspicious axillary lymph nodes and normal imaging of the breast.

Sonographic transvaginal bladder wall thickness: Does the measurement discriminate between urodynamic diagnoses?

Measurement of bladder wall thickness (BWT) using transvaginal ultrasound has previously been shown to discriminate between women with confirmed detrusor overactivity and those with urodynamic stress incontinence. Aim of the current study was to determine if vaginally measured BWT correlates with urodynamic diagnoses in a female population.

Sexual function after sacrocolpopexy

Pelvic organ prolapse affects approximately 50% of parous women over 50 years of age and has a lifetime risk of 30-50%. Vault descent or prolapse occurs in about 20% after hysterectomy and can have a negative effect on sexual function. Sacrocolpopexy is the gold standard of surgical treatment for apical prolapse in fit, sexually active patients. Few data exist which determine sexual function after sacrocolpopexy.

Sexual function after rectocele repair

Pelvic organ prolapse is a common condition among women with a prevalence of 11% and may affect the anterior, posterior, or apical compartment with a negative impact on sexual function.

How should bladder wall thickness be measured? A comparison of vaginal, perineal and abdominal ultrasound

Measurement of bladder wall thickness using transvaginal ultrasound has previously been shown to discriminate between women with diagnosed detrusor overactivity and those with urodynamic stress incontinence. So far, no comparison has been made between abdominal, perineal and vaginal route for the measurement of bladder wall thickness. The aim of this prospective study was to determine if abdominal, perineal and vaginal ultrasound measurements of bladder wall thickness are comparable with each other.

[Urinary incontinence]

Incontinence is a common age-dependent and increasing problem in women that may mainly present as stress incontinence, overactive bladder, mixed incontinence or other forms. A thorough history, gynaecological and neurological examination and urinalysis as initial step will lead to the diagnosis and treatment. If midstream urine is difficult to receive, a catheter urine will be easy to obtain. Further investigations as urodynamics, cystoscopy and ultrasound may be required. As initial step, stress incontinence should be treated with physiotherapy and pelvic floor exercises, if not successful with operations as suburethral slings. Slings have good long-term success rates of approximately 85 % with a low morbidity and can even be inserted under local anaesthetic. The treatment of idiopathic overactive bladder consists of bladder training, a behavioural therapy, and mainly anticholinergics. Anticholinergics may cause side effects particularly in the elderly who are under several medications that may add anticholinergic effects as antidepressants, antibiotics or antihistaminics.

Ctenidins: antimicrobial glycine-rich peptides from the hemocytes of the spider Cupiennius salei

Three novel glycine-rich peptides, named ctenidin 1-3, with activity against the Gram-negative bacterium E. coli, were isolated and characterized from hemocytes of the spider Cupiennius salei. Ctenidins have a high glycine content (>70%), similarly to other glycine-rich peptides, the acanthoscurrins, from another spider, Acanthoscurria gomesiana. A combination of mass spectrometry, Edman degradation, and cDNA cloning revealed the presence of three isoforms of ctenidin, at least two of them originating from simple, intronless genes. The full-length sequences of the ctenidins consist of a 19 amino acid residues signal peptide followed by the mature peptides of 109, 119, or 120 amino acid residues. The mature peptides are post-translationally modified by the cleavage of one or two C-terminal cationic amino acid residue(s) and amidation of the newly created mature C-terminus. Tissue expression analysis revealed that ctenidins are constitutively expressed in hemocytes and to a small extent also in the subesophageal nerve mass.
