The hybrid technique of pelvic organ prolapse treatment: apical sling and subfascial colporrhaphy

Introduction and hypothesis

The majority of patients with cystocele undergoing reconstructive surgery have combined defects of pubocervical fascia and uterosacral/cardinal ligament complex. In this regard, the simultaneous correction of both defects is rational. Furthermore, decreasing the use of synthetic materials in pelvic floor surgery is an important goal. The aim was to evaluate the objective and subjective cure rate of a hybrid technique: bilateral sacrospinous fixation using modern monofilament synthetic tape (apical sling) combined with the original technique of subfascial colporrhaphy.

Materials and methods

This prospective study involved 148 women suffering from cystocele combined with apical prolapse. We used the following criteria to evaluate the results of surgical treatment: results of the vaginal examination (POP-Q system), urodynamic tests, bladder ultrasound, special questionnaires (Pelvic Floor Distress Inventory [PFDI-20], Pelvic Floor Impact Questionnaire [PFIQ-7], Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire [PISQ-12], International Consultation on Incontinence Modular Questionnaire Short Form [ICIQ-SF]). All listed parameters were determined before the surgery and at control examinations at 1, 6, and 12 months after the treatment.

Results

At the 1-year follow-up, the objective cure rate for prolapse was 97.8%. The rate of anatomical recurrence was 2.2% (3 out of 138). The following long-term complications were noted: de novo urgency and stress urinary incontinence de novo in 2 (1.4%) and 4 (2.9%) patients, respectively. Comparison of the scores by the questionnaires also revealed a significant improvement in the quality of life in the postoperative period. Patient satisfaction rate was 97.1%.

Conclusion

The hybrid technique is an effective and safe uterus-sparing method for patients with advanced forms of cystocele combined with apical prolapse. This technique improves voiding function, quality of life, and provides a high satisfaction rate.

     

Femoral head avascular necrosis: correlation of MR imaging, radiographic staging, radionuclide imaging, and clinical findings

To better correlate the appearance of avascular necrosis (AVN) of the femoral head on magnetic resonance (MR) images with the stage of disease, MR images of 56 proved AVN lesions were compared with staging from corresponding radiographs (n = 56), Tc-99m scans (n = 41), and grade of symptoms (n = 28). Fractures complicating AVN were seen in 28 (50%) of 56 radiographs (radiographic stages III-V). With long repetition (TR) and echo delay (TE) times, a characteristic "double line sign" consisting of high signal intensity inside a low-intensity peripheral rim was seen in 45 lesions (80%). The central region within the rim was isointense with marrow fat on both short and long TR and TE images in 20 (71%) of 28 lesions uncomplicated by fracture (stages I-II) but in only four (14%) of 28 stage III-V lesions (P less than .001). Symptoms were least severe in lesions isointense with fat and most severe in lesions with low-signal central regions at short and long TRs and TEs. The peripheral double line sign on long TR/TE images may add specificity to the diagnosis of AVN by MR imaging. A chronologic pattern of central MR signal features is presented which may allow staging of AVN by MR imaging.     

Localization of the Usher syndrome type ID gene (Ush1D) to chromosome 10

The Usher syndromes (USH) are a group of autosomal recessive diseases characterized by progressive pigmentary retinopathy and sensorineural hearing loss. Five USH genes have been mapped and at least one additional gene is known to exist. By homozygosity mapping in a consanguineous family, a sixth USH gene has been localized. Clinical findings in the four affected children are consistent with established diagnostic criteria for Ush1. Linkage to known USH loci was excluded, and using two genomic DNA pools, one from the affected children and the other from the parents, 161 polymorphic markers evenly spaced across the autosomal human genome were screened. The location of the Ush1D gene was defined by the only region showing homozygosity by descent in the affected siblings, a 15 cM interval on chromosome 10q bounded by D10S529 and D10S573.      

Variations of sex hormone-binding globulin in thyroid dysfunction.

With the aim of understanding the variations of the levels of sex hormone-binding globulin (SHBG) in thyroid dysfunction, we studied the influence of factors that also modify SHBG, such as menopausal status, age, and body mass index (BMI) in women with hypothyroidism and hyperthyroidism, both overt and subclinical. Statistical analysis was performed by means of analysis of variance (ANOVA), stepwise multiple regression, and partial correlation. The ANOVA showed a significant statistical difference among the means of SHBG of all groups (p<0.01). The difference was due to the group that included hyperthyroid women. Multiple regression analysis showed that the main factors influencing SHBG were BMI and age, except for the hyperthyroid group, where the most important independent variables were triiodothyronine (T3) and thyroxine (T4). Partial correlation controlling the effect of BMI and age showed no association between SHBG and the other variables in all groups except for the subclinical hyperthyroid and hyperthyroid, where we found a significant association between SHBG and T4 and T3. The premenopausal or postmenopausal status did not modify SHBG levels. When the patients are taken as a whole, BMI, age, T4, and T3 all have an association with SHBG levels according to the multiple regression analysis.
