Sonography as a Diagnostic Tool in Midurethral Sling Complications: A Narrative Review

Despite the established safety and efficacy of midurethral slings (MUS), which are the current gold standard treatment for stress urinary incontinence (SUI), the potential for postoperative complications remains a significant concern for both healthcare professionals and patients. Meanwhile, sonography has emerged as a significant diagnostic tool in urogynecology, and one of the applications of this imaging modality may be the evaluation of complications arising from MUS procedures. This review, based on a comprehensive literature search, focuses on the use of pelvic floor ultrasound (US) in the context of MUS complications. It includes analyses of randomized controlled trials, prospective, and retrospective studies, covering preoperative and postoperative investigations, to assess complications such as persistent and recurrent SUI, urinary retention and obstructive voiding, de novo urgency/overactive bladder, vaginal exposure, sling erosion, pain, and hematoma. The review critically examines the existing literature, with a particular focus on recent publications. Despite the variability in findings, it appears that for each of the discussed complications, the application of pelvic floor US can significantly support the diagnostic and therapeutic process. The paper also identifies potential future directions for the development of US applications in diagnosing MUS complications.

Sexual function in women with pelvic organ prolapse and surgery influence on their complaints

Sexual health is an essential component of women's wellbeing. Women with pelvic organ prolapse (POP) often suffer from sexual dysfunction. The current review focuses on the impact of POP as well as surgical POP repair on sexual function. A variety of techniques are discussed in relation to this issue, including native tissue repair (NTR), transvaginal mesh (TVM) and sacrocolpopexy (SCP). The majority of studies utilise validated questionnaires to assess sexual function in women pre- and post-POP repair and FSFI (Female Sexual Function Index) and PISQ-IR (Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire-IUGA revised) are among the most commonly used. According to the available data, surgical management of POP usually results in improved or unchanged scores in sexual function, regardless of the type of procedure used. SCP appears to be the preferred surgical management for women with apical vaginal prolapse that minimises the risk of dyspareunia as compared to vaginal techniques.

Expression of Fucosyltransferase 4 (FUT4) mRNA Is Increased in Endometrium from Women with Endometriosis

Endometriosis is a common gynecological disorder defined as the presence of endometrial-like tissue (glands and stroma) outside the uterus. The etiopathogenesis of endometriosis is still poorly recognized. It is speculated that stage-specific embryonic antigen 1 (SSEA-1)-positive stem-like glandular epithelial cells may contribute to the development of the disease. The synthesis of SSEA-1 is mediated by fucosyltransferase 4 encoded by the FUT4 gene. Therefore, this study aimed to evaluate the specific expression of FUT4 mRNA in biopsies of the endometrium from women with and without endometriosis. FUT4 mRNA levels were examined in 49 women with laparoscopically confirmed endometriosis and 28 controls by means of quantitative reverse-transcription polymerase chain reaction (qRT-PCR). The expression of FUT4 mRNA was significantly increased in the endometrium of patients with endometriosis when compared to the controls (p < 0.0001). Expression of FUT4 mRNA in the endometrium was correlated with the severity of endometriosis (rs = 0.5579, p < 0.0001); however, there were no differences in endometrial FUT4 mRNA expression when comparing endometriotic lesions from various locations. The discriminatory ability of FUT4 mRNA expression was evaluated by receiver-operating characteristics (ROC), which showed high statistical significance (AUC = 0.90, p < 0.0001), thus indicating that an increased level of endometrial FUT4 mRNA may serve as a specific marker for endometriosis.

Endometriotic Peritoneal Fluid Stimulates Recruitment of CD4+CD25highFOXP3+ Treg Cells

Endometriosis is a common gynecological disorder characterized by the presence of endometrial-like tissue outside the uterus. The disease is associated with disturbed local and systemic immunity. It has been reported that the proportion of CD4⁺CD25^highFOXP3⁺ Treg cells may be significantly increased in the peritoneal fluid of patients with endometriosis. Therefore, the aim of our study was to investigate whether the proportions of Treg cells in the peritoneal cavity of patients with endometriosis are related to the chemotactic and stimulatory activity of the local peritoneal milieu. The peritoneal fluid was collected from 13 women with ovarian endometriosis and 12 control women without the disease. T cell populations were analyzed by flow cytometry, cytokines and chemokines were evaluated using the cytometric bead kit, and cell chemotaxis was studied by cell migration assay. We confirmed that the proportions of Treg cells are increased in the peritoneal fluid of women with endometriosis as compared to the control women. Endometriosis was also associated with elevated concentrations of IL-6, IL-10, and TGF-β1/2 as well as CCL20, CXCL8, CXCL9, and CXCL10. We did not reveal any changes in the proportion of peritoneal Th17 cells and concentrations of IL-17A. Peritoneal Treg cells positively correlated with concentrations of TGF-β, IL-10, and CCL20. Endometriotic peritoneal fluid stimulated chemotaxis of both CD4⁺ and Treg cells. This chemotactic activity positively correlated with concentrations of CCL20. CCL20 stimulated the migration of Treg cells, and the chemotactic activity of the endometriotic peritoneal fluid was inhibited by neutralizing anti-CCL20 antibodies. These results imply that increased proportions of the peritoneal Treg cells in women with endometriosis may result from attraction and activation by local chemokines and cytokines, especially CCL20 and TGF-β. Since Treg cells contribute to the immunopathogenesis of endometriosis, their chemotaxis and activation may be considered as a target for therapeutic intervention.

Peritoneal Fluid from Patients with Ovarian Endometriosis Displays Immunosuppressive Potential and Stimulates Th2 Response

Endometriosis is a common gynaecological disorder characterized by the ectopic growth of endometrial tissue outside the uterine cavity. It is associated with chronic pelvic inflammation and autoimmune reactivity manifesting by autoantibody production and abrogated cellular immune responses. Endometriotic peritoneal fluid contains various infiltrating leucocyte populations and a bulk of proinflammatory and immunoregulatory cytokines. However, the nature and significance of the peritoneal milieu in women with endometriosis still remains obscure. Therefore, the aim of the present study was to investigate the immunoregulatory activity of the peritoneal fluid (PF) from women with endometriosis. The peritoneal fluid samples were collected during laparoscopic surgery from 30 women with and without endometriosis. Immunoregulatory cytokines (IL-2, IL-4, IL-6, IL-10, IL-17A, IFN-γ and TNF) and chemokines (CCL2, CCL5, CXCL8 and CXCL9) were evaluated in PF and culture supernatants generated by unstimulated and CD3/CD28/IL-2-stimulated CD4⁺ T cells cultured in the presence of PF. The effect of PF on the generation of Treg and Th17 cells in CD4⁺ T cell cultures, as well as the natural cytotoxic activity of peripheral blood mononuclear cells, was also investigated. Concentrations of IL-6, IL-10, CCL2, CXCL8 and CXCL9 were significantly upregulated in the PF from women with endometriosis when compared to control women, whereas concentrations of other cytokines and chemokines were unaffected. The culturing of unstimulated and CD3/CD28/IL-2-stimulated CD4⁺ T cells in the presence of endometriotic PF resulted in the downregulation of their IL-2, IFN-γ, IL-17A and TNF production as compared to culture medium alone. On the other side, endometriotic PF significantly stimulated the production of IL-4 and IL-10. Endometriotic PF also stimulated the release of CCL2 and CXCL8, whereas the production of CCL5 and CXCL9 was downregulated. Endometriotic PF stimulated the generation of Treg cells and had an inhibitory effect on the generation of Th17 cells in cultures of CD4⁺ T cells. It also inhibited the NK cell cytotoxic activity of the peripheral blood lymphocytes. These results strongly imply that the PF from patients with endometriosis has immunoregulatory/immunosuppressive activity and shifts the Th1/Th2 cytokine balance toward the Th2 response, which may account for deviation of local and systemic immune responses. However, a similar trend, albeit not a statistically significant one, was also observed in case of PF from women without endometriosis, thus suggesting that peritoneal milieu may in general display some immunoregulatory/immunosuppressive properties. It should be stressed, however, that our present observations were made on a relatively small number of PF samples and further studies are needed to reveal possible mechanism(s) responsible for this phenomenon.

Epidemiological Features of the Bladder Neck Rest Position and Mobility

The data concerning epidemiological determinants of the bladder neck (BN) mobility are scarce. The aim of the study was to determine epidemiological features and identify factors influencing BN position at rest and BN mobility in patients without pelvic organ prolapse (POP). Seven hundred and ninety-six patients that attended two outpatient clinics were enrolled in the study. Position and mobility of the BN were measured with the use of pelvic floor ultrasound. Demographic and functional factors that were hypothesized to influence BN mobility were assessed. Vaginal deliveries (VDs) and age ≥65 were associated with lower BN position at rest. Higher BN mobility was observed in women with stress urinary incontinence (SUI). In obese women, higher BN position and lower BN mobility was observed compared to non-obese women, and it was correlated with longer urethras in this group of patients. VDs and their number were associated with increased BN mobility, independently of body mass index (BMI). To conclude, obesity, VDs, and age are factors associated with changes in bladder neck position at rest and its mobility. Higher BMI correlates with restricted BN mobility, and, therefore, the incidence of SUI in obese patients is probably not connected to BN hypermobility.

Oxidative stress markers in saliva and plasma differ between diet-controlled and insulin-controlled gestational diabetes mellitus

OBJECTIVES

The aims of the study were as follows: to investigate possible differences between plasma oxidative status (OS) in late-onset GDM and well-characterized healthy pregnant women (oral health, diet); to verify the existence of possible differences between GDMG1 (diet-treated) and GDMG2 (insulin-treated GDM); to determine whether oxidative stress markers could be detected in saliva.

MATERIAL AND METHODS

A total of 89 pregnant women (n = 89; 59 with GDM and 30 controls) were evaluated. Malondialdehyde (MDA), total antioxidant capacity (ORAC), inactivation of aldehyde dehydrogenase (I_ALDH), activity of glutathione peroxidase (GPx) and glutathione transferase (GST)) in plasma and/or saliva were analyzed.

RESULTS

The activity of GPx and GST in plasma was higher in GDMG2 as compared to GDMG1 and controls. Also, in GDMG2, elevated concentrations of salivary MDA and higher I_ALDH were observed. In contrast, GDMG1 had higher plasma ORAC and lower GPx activity as compared to controls, probably due to low-energy diet, high in antioxidants and fibers. Salivary and plasma OS were correlated and most significant for ORAC.

CONCLUSION

Oxidative stress were not observed in GDMG1 but were confirmed to be moderate in GDMG2. However, large variability of the analyzed markers in GDM groups encourages screening of all patients, regardless of the treatment option. Saliva may be considered useful for the estimation of oxidative stress levels in GDM populations.

Demographic risk factors for mid-urethral sling failure. Do they really matter?

Age, obesity and vaginal deliveries (VD) are recognized risk factors for stress urinary incontinence (SUI). According to many authors, the abovementioned risk factors for incontinence also increase the risk of mid-urethral sling (MUS) failure. Our aim was to evaluate the objective and subjective effectiveness of retropubic MUS in 12 months observation, relative to the three potential risk factors of failure: obesity, age and VDs. A prospective observational study including 238 women who underwent retropubic MUS implantation was performed. Patients were divided into subgroups: obese vs non-obese, <65 vs ≥65 years old and no history of VD vs ≥1 VD. Follow-up took place between 6 and 12 months post-surgery. Cough test, 1-hour pad test, pelvic floor ultrasound examination, and Incontinence Impact Questionnaire 7 (IIQ-7) results were assessed pre- and post-operatively. Of the 238 patients, 208 (86.3%) completed a minimum follow-up period of 12 months. Significant improvement in the pad test was observed in all patients (83.2 ± 78.6 g vs 0.7 ± 3.3 g). Negative cough test results were obtained in over 94% of patients. Significant improvement in the IIQ7 results was observed in all patients (74.2 ± 17.7 vs 5.5 ± 13.4). No significant differences in all the analyzed parameters with regard to BMI, age and parity were observed. No combination of risk factors influenced the objective and subjective cure rates. Our study demonstrated that older age, obesity and history of VDs have no impact on objective and subjective sling effectiveness in a short term observation. There is no influence of combined demographic features on the failure risk.

Demographic features of female urethra length

AIMS

To determine cohort urethral length, identify epidemiological factors influencing the parameter and to establish the percentage of cases with clinically relevant outsized urethras.

METHODS

Prospective cohort study conducted in two tertiary clinical centers between 2013 and 2017. Nine hundred and twenty seven consecutive adult, Caucasian females attending outpatients' clinics were included. The urethral length has been measured in pelvic floor ultrasound examination. The exclusion criteria were inadequate bladder filling (<200 mL; >400 mL), previous history of pelvic floor surgery, and no consent.

RESULTS

Urethral length varied from 19 to 45 mm. The distribution of the examined parameter was normal. Obese patients had significantly longer urethras as compared to non-obese subjects. Number of vaginal deliveries was connected with shorter urethral length. The limitations of the study are: analysis only of Caucasian patients and subjects without previous pelvic floor surgeries.

CONCLUSIONS

Differences in urethral length in the female population were demonstrated. Thirty percent of patients have atypical urethras that may be a risk factor for sling surgery failure. We therefore postulate introduction of urethral measurement before the procedure.

Is Bariatric Surgery a Prophylaxis for Pelvic Floor Disorders?

Introduction

Obesity is one of the well-documented risk factors of pelvic floor disorders (PFDs). The PFDs include urinary and fecal incontinence (UI, FI) and pelvic organ prolapse (POP). Surgery-induced weight loss improves different kinds of incontinence as well as POP symptoms. However, there is a lack of evidence how bariatric surgery influences pelvic floor anatomy and function in women without previous PFDs and whether it may be concerned as PFD prophylaxis tool.

Materials and Methods

The present analysis is a prospective, non-randomized case-control study from January 2014 to September 2017. Participants underwent pelvic floor ultrasound examination with bladder neck position estimation at rest, during levator ani tension, and at Valsalva maneuver before surgery and 12–18 months after. Pelvic organ prolapse quantification (POPQ) > 2 stage and PFD complaints were the exclusion criteria.

Results

Fifty-nine patients underwent bariatric surgery (57 sleeve gastrectomy and 2 gastric bypass). Mean BMI decreased from 43.8 ± 5.9 to 29 ± 4.6 kg/m² after surgery (p < 0.001). Statistically significant higher position of the bladder neck at rest, during tension, and at Valsalva maneuver (p < 0.05) was shown after surgery. We did not demonstrate differences in bladder neck mobility and bladder neck elevation at tension after weight loss.

Conclusions

Bariatric surgery is associated with a betterment of bladder neck position at rest, tension, and Valsalva maneuver in women without PFDs. We postulate that bariatric surgery may be a tool for PFD prevention. It does not improve levator ani function and does not limit bladder neck mobility, which implicates that it has no influence on preexisting pelvic dysfunction.

Does the suburethral sling change its location?

OBJECTIVES

To ascertain whether a phenomenon of sling migration exists after suburethral sling placement, whether this might be responsible for suboptimal sling location and persistent incontinence, and whether a link exists between sling dislocation or migration and risk factors, such as obesity or age.

METHODS

The present prospective cohort study was carried out in a group of 244 patients who underwent retropubic sling implantation. Sling location was determined by means of pelvic floor ultrasound, and calculated relative to the individual patient's urethral length measured before the procedure. The sling location was visualized on 1 day, and 1 and 6 months post-surgery. Overweight/obese and elderly patients were analyzed separately to assess the possible influence of those factors on sling location.

RESULTS

The mean urethral length in the studied cohort was 28.76 ± 3.67 mm. The mean tape position 1 day post-surgery was 66.18 ± 8.43% of the urethral length, and it did not change 1 and 6 months post-surgery in the whole group. Similar results were obtained in elderly and overweight/obese patients.

CONCLUSIONS

Suboptimal sling location appears to result from incorrect surgical technique, and should be diagnosed and treated early after the primary surgery. Sling location does not change after mid-term follow up.

Endometriotic lesions mimicking advanced ovarian cancer - A case report and a review of the literature

BACKGROUND

Approximately 2-5% of women affected by endometriosis are postmenopausal. The disease may simulate various malignancies. A case of endometriosis in a postmenopausal woman, spreading similarly to ovarian cancer, is reported. A broad review of existing literature on postmenopausal endometriosis, endometriosis involving the urinary tract, and the links between endometriosis and cancer are also presented.

CASE DESCRIPTION

A 51-year-old woman was diagnosed with a pelvic mass. She complained of pain in the lower abdomen that began three weeks prior, and had no history of dysmenorrhea, acyclic pelvic pain, or infertility. CT scan revealed a solid and cystic tumor in the region of the right adnexa, infiltrating the surrounding tissues, with possible infiltration of the urinary bladder, as well as soft-tissue lesions of the small intestinal mesentery. Bilateral hydronephrosis and distension of the ureters were also present. A malignant neoplasm of the ovary or the corpus uteri was suspected. Total abdominal hysterectomy and appendectomy were performed. A superficial infiltration of the urinary bladder was also excised. The pathology report revealed endometriotic foci in the tumor and in the bladder infiltration, as well as an endometriotic cyst in the right ovary. Two years postoperatively the patient is disease-free and in good condition.

CONCLUSIONS

Clinicians should remain conscious of the possibility of endometriosis mimicking advanced ovarian cancer and infiltrating the peritoneum and internal organs of the abdominal cavity, including the urinary tract. Imaging techniques, including CT and MRI, are not always effective in establishing the correct diagnosis preoperatively.

Respiratory Function and Language Abilities of Profoundly Deaf Adolescents with and without Cochlear Implants

The objective of the study was to investigate whether hearing loss has an effect on the ventilatory functional capability and whether possible deviations of ventilatory variables from the reference ranges could have to do with the language abilities of deaf adolescents. Spirometric evaluations were performed in 72 prelingually profoundly deaf adolescents with and without cochlear implants (CI) and compared with the results of a control group consisting of 48 participants with normal hearing (CG). The deaf adolescents showed a significantly lower vital capacity (VC), forced vital capacity (FVC), and expiratory flows (PEF and MEF) compared with their hearing peers. The adolescents with CI demonstrated predominantly the oral communication mode, which however did not affect the students' education achievements. Perseverance of oral communication was also associated with higher FVC and PEF, compared with deaf participants without CI. We conclude that sensory deprivation of prelingually deaf adolescents affects the respiratory system function. The use of oral communication seems to have beneficial effects on respiratory performance in profoundly deaf adolescents.

Vaginal excision of the sub-urethral sling: analysis of indications, safety and outcome

INTRODUCTION

Sling techniques are the method of choice in stress urinary incontinence management, despite the high rates of complications leading sometimes to the necessity of re-operation, and the tape transection and resection are of the greatest importance. The study was aimed at analyzing the indications, technique and effects of transvaginal tape excision.

MATERIAL AND METHODS

A retrospective study including 100 patients who underwent surgical removal of the sub-urethral sling in Evangelisches Krankenhaus Hagen-Haspe was conducted. The analyzed measures were: sling type, onset of symptoms, rates of particular complications, safety and outcome of the operative procedure.

RESULTS

Most complications occurred in the first 2 years after surgery. The most common indications for re-operation were: overactive bladder (OAB) (64%), persistent stress urinary incontinence (SUI) (59%), pain (40%), urinary retention (40%), and erosion (29%). Some of the complications co-existed (i.e. vaginal erosion with postoperative pain, infections with urinary retention). During the procedure 1 bladder was injured and 1 patient had a hematoma. In women with OAB, 24-hour frequency decreased from 13.3 to 8.5 (p < 0.001), the mean voiding volume increased from 131.7 to 216.4 ml (p < 0.001), and nocturia increased from 3.28 to 1.19 (p < 0.001). Intensity of urgency decreased from 8.78 to 0.92 in the 10-point visual score (p < 0.001). Pain and urinary retention resolved in 39 out of 40 patients (p < 0.0001). The rate of SUI increased from 59% to 83% (p < 0.001).

CONCLUSIONS

Sling removal is safe and associated with a minimal rate of complications. Removing the tape causes resolution of most of the complications, but SUI recurs or worsens.

Assessment of patient acceptability of medical treatment in case of non-viable first trimester pregnancy

OBJECTIVES

The aim of the present study was to assess patient acceptability and satisfaction with medical treatment (vaginal misoprostol) of non-viable first trimester pregnancy.

MATERIAL AND METHODS

A total of 64 women, treated with vaginal misoprostol for non-viable first trimester pregnancy between October 2012 and December 2012 at the First Department of Obstetrics and Gynecology Medical University of Warsaw, were included in this questionnaire-based study. Questions pertaining to advantages and disadvantages of misoprostol treatment as compared to potential surgical intervention were used. The respondents also determined whether they would choose medical treatment if they were to decide again. The Visual Analogue Scale (VAS) was used to assess pain and bleeding intensity.

RESULTS

Medical treatment was successful in 57 and surgical treatment was needed in 7 women. Average pain and bleeding intensity were 5.8 and 5.3, respectively. The most common side effects included diarrhea (27%), dizziness (22.2%), nausea (15.9%), and chills (15.6%). The most important advantages of misoprostol therapy were avoidance of the risk of uterine perforation (96.4%) and formation of intrauterine adhesions (74.6%), whereas the most significant disadvantages were prolonged bleeding (21.4%), pain (21.4%), and longer treatment duration (42.9%). Overall, 95.6% of the patients with successful treatment outcome declared they would choose this procedure if they were to decide again, as compared to 85.6% of women with treatment failure (p > 0.05).

CONCLUSIONS

Medical treatment with vaginal misoprostol is acceptable and well-tolerated by the vast majority of women with non-viable first trimester pregnancy. Satisfaction is expressed by both, respondents with successful as well as unsuccessful treatment outcome.

Postradiation carcinosarcoma of the corpus uteri--a case report

INTRODUCTION

Radiation therapy is a very effective treatment modality, commonly used for numerous gynecological malignancies, e.g. cervical cancer. Unfortunately, ionizing radiation is associated with numerous side effects, including secondary cancer formation. A case of carcinosarcoma of the corpus uteri in a woman with a history of pelvic irradiation for cervical carcinoma is reported. The literature has been reviewed to present the incidence, optimal management, and prognosis in cases of postradiation uterine carcinosarcoma.

CASE

A 55-year-old woman with a history of pelvic radiotherapy for cervical cancer five years earlier was diagnosed with a pelvic mass. Endovaginal ultrasound examination revealed a solid and cystic tumor, 12.5 cm in diameter. The patient was scheduled for surgery. Gross examination revealed an enlarged, plain corpus uteri, 12 cm in diameter. Both adnexa were normal. Pelvic and abdominal peritoneum were macroscopically normal and normal on palpation. Iliac and obturatory lymph nodes were enlarged on both sides. Radical hysterectomy, omentectomy, and ilio-obturator lymph node dissection were performed. The pathology report revealed carcinosarcoma of the corpus uteri with lymph nodes metastases--FIGO IIIC1. No adjuvant treatment was given. The patient is still alive and disease-free one year after surgery.

CONCLUSIONS

Clinicians should.remain conscious of the potential carcinogenic effect of radiation therapy. Uterine carcinosarcoma may occur years after radiotherapy applied for cervical cancer. Therefore, long-term control following pelvic irradiation is always necessary.

Complications of sub-urethral sling procedures

Approximately one-third of the female population has been estimated to suffer from stress urinary incontinence. Surgical management of this disorder has been an area of ongoing innovation since the beginning of the 20th century. Better understanding of the underlying patomechanisms resulted in the invention of suburethral sling, that proved to be very effective in terms of the cure rates. The introduction of sling techniques also caused a considerable reduction of the rates of intra- and postoperative complications of incontinence treatment. Unfortunately modern anti-incontinence surgery continues to be associated with a high risk of both, perioperative morbidity and long-term adverse outcomes, even with the recently introduced single-incision techniques. The article focuses on intra- and postoperative complications of sling techniques in anti-incontinence surgery. Both, common and rare adverse outcomes are widely discussed.

[Assessment of efficacy and safety of medical treatment of non-viable first trimester pregnancy]

OBJECTIVES

The aim of our study was to assess the efficacy and safety of medical treatment of non-viable first trimester pregnancy.

MATERIAL AND METHODS

We analyzed 50 cases of women diagnosed with non-viable first trimester pregnancy: missed abortion (79.6%) or anembryonic pregnancy (20.4%), who were admitted and treated at the First Clinic of Obstetrics and Gynecology Medical University of Warsaw, between June 2011 and February 2012. The diagnosis was made after two ultrasound examinations, performed at least one week apart. None of the patients manifested symptoms of imminent miscarriage. All women received medical treatment - misoprostol administered vaginally or in cases of excessive bleeding in the course of the procedure, sublingually - according to our own scheme. The patients were informed that any moment they could decide to discontinue medical treatment and ask for surgery Initially, 4 tablets containing misoprostol (800 mcg) were administered vaginally A control ultrasound examination was performed 6 hours later. If expulsion of the gestational sac was completed, the patient was discharged. If the gestational sac was still present in the uterus, an additional dose of misoprostol was administered: 4 tablets vaginally or if excessive bleeding occurred, 3 tablets (600 mcg) sublingually. Another ultrasound examination was performed after 6 hours from the second dose and the patient was discharged if the expulsion of the gestational sac was completed. If the procedure failed, it was repeated in the same manner the next day. D&C was performed in cases of excessive bleeding, failure of medical treatment after 48 hours, patient decision to discontinue medical treatment or suspected incomplete abortion after menstrual bleeding. For women who completed the medical treatment, control visits were scheduled 14 days after hospital discharge and after menstrual bleeding, if incomplete abortion was suspected.

RESULTS

D&C was performed in 12% of patients because of failure of medical treatment after 48 hours, excessive bleeding or incomplete abortion after menstrual bleeding. Additional 6% of women decided to discontinue medical treatment and demanded D&C before completing 48 hours of treatment. The mean dose of misoprostol administered until the expulsion of the gestational sac was 1.404 g (7.02 tablets). In 60% of cases the expulsion was completed before 12 hours from the beginning of the procedure. In multiparae, the time until expulsion did not exceed 6 hours more frequently than in nulliparae (50 vs. 24.14%, p<0.05). The duration of the procedure did not exceed 24 hours in any of the multiparae. Among women who did not undergo D&C, 46.2% were diagnosed with complete abortion during the control visit, 74 days after the hospital discharge, and 53.8%- after menstrual bleeding. No serious side effects of misoprostol, influencing its safety, were observed.

CONCLUSIONS

Medical treatment is a highly effective and safe method of management of non-viable first trimester pregnancy. Because of the currently existing variety of protocols, it is recommended to implement standard schemes of misoprostol administration and control visits. It seems that there is no need for hospitalization during the procedure. Outpatient care may contribute to further reduction of the D&C rate. Limited surgery rate, apart from decreasing the risk of iatrogenic damage of the uterus, additionally leads to lower treatment costs as it eliminates the necessity of hospitalization and anesthesia.

Spirometric measurements and physical efficiency in children and adolescents with hearing and visual impairments

The objective of the study was to investigate whether a sensory impairment has an effect on functional capabilities of the respiratory system and whether possible deviations from reference ranges of selected parameters might indicate a decrease of physical efficiency. Vital capacity (VC), forced vital capacity (FVC), forced expiratory volume in 1 second (FEV1), peak expiratory flow (PEF), forced expiratory flow of 25-75% (FEF25-75), maximum voluntary volume (MVV), and maximum oxygen uptake VO2 max were measured in 86 deaf and 102 blind children and adolescents, and in a matched group of hearing controls. We found a significant influence of deafness on PEF (P<0.01), FEF25-75 (P<0.05), and MVV (P<0.05). As compared with the control subjects, mean VC was significantly lower in blind adolescents (P<0.05). Our results seem to suggest that both sensory defects during childhood and adolescence affect functional capabilities of the respiratory system.

Spirometric values and aerobic efficiency of children and adolescents with hearing loss

Vital capacity (VC), forced expiratory volume in 1 s (FEV(1)), peak expiratory flow (PEF), mean forced expiratory flow (FEV(25-75)), and maximum voluntary volume (MVV) were measured in 36 girls and 36 boys with hearing loss and compared with the same number of normal healthy children, all subjects were aged 10-16 years. They participated in an exercise test to calculate VO(2 max) in order to determine their physical efficiency. We found that all spirometric indices tended to be lower in deaf children, in all age-groups studied and irrespective of gender, compared with their hearing counterparts; the differences assumed significance with respect to PEF and MVV (P<0.05). Moreover, some deaf children had an appreciably lower level of VO(2 max) compared with hearing children. Our results demonstrate that sensory deprivation of deaf children affects functional capabilities of the respiratory system.
