The role of the "beret" sign and other markers in ultrasound diagnostic of the acrania-exencephaly-anencephaly sequence stages.

INTRODUCTION: Neural tube defects (NTDs) are a group of heterogeneous congenital anomalies of the central nervous system (CNS). Acrania is a non-NTD congenital disorder related to the CNS. It can transform into anencephaly through the acrania-exencephaly-anencephaly sequence (AEAS). In AEAS, the cerebral tissue is not protected and is gradually destroyed due to exposure to the harmful effect of amniotic fluid and mechanical injuries. These lead to exencephaly and then into anencephaly. In contrast to primary anencephaly (NTDs), this type of anencephaly authors suggests calling secondary anencephaly. OBJECTIVE: Analysis of the known prenatal ultrasonography (US) signs associated with AEAS. Simultaneously, the authors propose a new sign in the differentiation of acrania from exencephaly and anencephaly, called the "beret" sign. METHODS: It is a two-centre retrospective observational study. As part of the study, 4060 US scans were analyzed. RESULTS: In 10 cases, the absence of calvarium was diagnosed, allowing recognition of either AEAS stages or primary anencephaly. In 5 cases, cerebral structures were enclosed by an inertial rippled thin membrane, with a smooth outer contour. Between the described membrane and the brain structures, a thin anechoic space corresponding to cerebrospinal fluid was observed. This sign was defined as the "beret" sign. In these cases, acrania was diagnosed. In three cases calvarium was missing. The brain structures had an irregular appearance, did not wave and remained motionless. The outer contour was unequal as if divided into lobes. Amniotic fluid was anechoic. Exencephaly was diagnosed in these cases. In two cases calvarium, brain structures, and meninges were missing. The "frog eyes" sign and slightly echogenic amniotic fluid were visible. In this case, anencephaly was diagnosed. CONCLUSIONS: The "beret" sign seems to be a promising tool in the diagnosis of acrania. Furthermore, echogenicity of amniotic fluid could be useful during differentiation between primary and secondary anencephaly.

The influence of nebivolol on the activity of BRL 37344 - the ß3-adrenergic receptor agonist, in the animal model of detrusor overactivity.

AIMS: The cardiotoxic effects of antimuscarinics constitute a significant restriction in their application in elderly people. Overactive bladder syndrome pharmacotherapy using compounds with cardioprotective properties would seem an ideal solution. The main goal of the study was to assess the impacts of nebivolol (NEB) on the activity of BRL 37344 - ß3-adrenergic receptor (ß3AR) agonist, in the animal model of detrusor overactivity. As both these substances can impact on the cardiovascular system, their effect on the parameters of this system and diuresis was also examined. METHODS: Retinyl acetate (RA; 0.75%) solution was used to induce detrusor overactivity in female Wistar rats. BRL and/or NEB were administered intra-arterially during cystometry in a single dose (2.5 or 5, 0.05 or 0.1 mg/kg, respectively). In addition, a 24 hours measurement of heart rate, blood pressure, and urine production was carried out. RESULTS: NEB (0.05 mg/kg) and BRL (2.5 mg/kg) monotherapy proved to have no influence on the cystometric parameters of animals with RA-induced detrusor overactivity. NEB at 0.1 mg/kg resulted in a drop in the detrusor overactivity index, similarly to BRL at 5 mg/kg. Coadministration of NEB and BRL, both at ineffective doses, decreased the detrusor overactivity index and ameliorated the nonvoiding contractions. ß3AR stimulation proved to induce tachycardia and hypertension. NEB at 0.05 mg/kg proved to ameliorate detrusor overactivity and have preventive properties against adverse cardiovascular effects of the ß3AR agonist. CONCLUSIONS: The combined application of the ß3AR agonist and NEB may improve detrusor overactivity without affecting the heart rate, blood pressure, and urine production.

Extensive postpartum urinary retention successfully treated with clean intermittent catheterization.

We present a case of extensive urine retention after vaginal delivery. Postpartum urinary retention occurs in 0.7 to 0.9% of vaginal deliveries. In the literature, mediolateral episiotomy, epidural analgesia, perineal lacerations, macrosomic birth and prolonged 2nd stage of labor are suggested as risk factors for postpartum urine retention.

Ascites Index - a novel technique to evaluate ascites in ovarian hyperstimulation syndrome: a concept-proof study.

OBJECTIVES: Controlled ovarian hyperstimulation is an important step in infertility treatment. In some cases, however, ovar-ian hyperstimulation syndrome (OHSS) can occur. In its severe forms, ascites is likely to develop, associated with dyspnea. The aim of this study was to explore the usefulness of Ascites Index (AsI), a new tool for quantitative determination of ascites in patients with OHSS, to obtain data for planning further trials. MATERIAL AND METHODS: Twelve patients with OHSS and ascites were included in the study. All patients were admitted to the hospital because of abdominal pain and dyspnea due to increasing ascites. Ultrasound measurements of ascites extent were performed in four external quadrants of the abdomen. Pockets of free fluid were measured. The obtained values were totaled, forming the Ascites Index (AsI), similarly to the amniotic fluid index. Because of dyspnea, paracentesis was performed in all cases. RESULTS: Median AsI at which patients reported dyspnea was 29.0 cm (range 21.6-38.6 cm). At AsI values less than 21.6 cm, no dyspnea was observed in any of the 12 studied patients. To avoid complications, 2000 mL of ascitic fluid was collected in each patient. After paracentesis, range of AsI decreased to 12.1-14.5 cm. CONCLUSIONS: The proposed AsI seems to be a promising tool for estimating and monitoring the ascites extent in OHSS. It can be estimated using basic ultrasound equipment. AsI requires further studies for standardization and transferability to other causes of ascites.

Primary ovarian Burkitt's lymphoma: a rare oncological problem in gynaecology: a review of literature.

PURPOSE: This review presents the information about epidemiology, clinical manifestation, diagnosis and treatment of primary ovarian Burkitt's lymphoma (BL), including a literature search of available BL cases. The purpose of this review is to draw clinicians' attention to the possibility of ovarian BL occurrence, which may be important in the differential diagnosis of ovarian tumours. METHODS: PubMed and Web of Science databases were searched using the keywords ''Burkitt's'', ''Lymphoma'', ''Ovarian'', ''Primary'', ''Burkitt's lymphoma''. Only cases with histopathologically confirmed diagnosis of primary ovarian BL were included in this review. RESULTS: Fifty articles, reporting cases with an ovarian manifestation of primary non-Hodgkin's lymphoma, were found. Twenty-one cases with a histopathologically confirmed BL were evaluated to compare various manifestations, treatment and prognosis in ovarian BL. CONCLUSIONS: Primary ovarian BL is a rare condition, included in the entity of non-Hodgkin lymphoma. The tumour can occur uni- or bilaterally in the ovaries with major symptoms such as abdominal pain or a large abdominal mass. Differential diagnosis, based on imaging features and pathological examination of the specimens, is essential for further treatment due to various aetiology of ovarian tumours. Although most of the patients suffering from ovarian BL underwent surgery after the ovarian tumour had been detected, surgical treatment is not the treatment of choice in patients with ovarian lymphoma. The mainstay of therapy is chemotherapy without further surgery. The prognosis is better if the chemotherapy protocol is more aggressive and followed by prophylactic central nervous system chemotherapy. Nowadays, multiagent protocols are administered, which improves the survival rate.

Secondary dysmenorrhea due to a rudimentary, non-communicating functional uterine horn.

Unicornuate uterus with a rudimentary horn is a rare congenital Müllerian anomaly, which may lead to many obstetrical and gynaecological complications. This pathology occurs in approximately 1/100 000 women. A rudimentary horn forms due to insufficient development of the Müllerian duct. The diagnosis of this anomaly is usually delayed, as it remains asymptomatic until adolescence and its main symptom is dysmenorrhea.

Use of a levonorgestrel-releasing intrauterine device for menorrhagia treatment during adjuvant therapy of adrenocortical carcinoma with mitotane.

Adrenocortical carcinoma is a rare tumour with high malignancy and poor prognosis. This tumour is rarely diagnosed in the reproductive age. Complete surgical resection is the only curative treatment for adrenal cancer in all stages. After surgery adjuvant chemotherapy is required. Mitotane is the most important drug in adrenal cancer chemotherapy. Mitotane's mode of action is not entirely explained. Animal studies have shown that the substance exerts a direct cytotoxic effect on the cells of the adrenal cortex. This activity is selective, progressive and affects only the zona reticularis and fasciculata of the adrenal cortex. Mitotane inhibits cortisol synthesis by disrupting the chain of cholesterol. It has been suggested, that mitotane also affects the peripheral metabolism of steroids, especially of transcortin (CBG). This results in an increase of CBG blood concentration and a reduction of the amount of free hormones.

3D Power Doppler vascular indices as a novel technique in assessing the outcome of minimally invasive techniques in uterine fibroids treatment.

Uterine fibroids are considered to be the most frequent female benign tumours. The most common reported symptoms of fibroids are heavy menstrual bleeding and painful menstruation, pelvic pain, urinary problems, constipation, as well as infertility and recurrent pregnancy loss. The mainstay of fibroid treatment is surgery, but nowadays minimally-invasive techniques are growing in popularity. Vascularity of fibroids may play a role in the outcome of these techniques, which is why it is important to find an objective, reproducible technique to measure the vascularization before and after the procedure. The 3D Power Doppler vascular indices (3DPDVI) allow objective assessment of vascularization in the entire volume of the tumour. Initially this technique was mostly used in experimental imaging phantoms, but recently many studies focus on the clinical utility of this technique. Power Doppler allows to obtain information on vascularity in the area of interest, while 3DPDVI can be objectively calculated by the Virtual Organ Computer-aided AnaLysis (VOCAL™) software. 3DPDVI showed high reproducibility in most of the studies. This technique has an important role in monitoring the outcome of minimally invasive procedures in fibroid treatment, because they affect vascularity of the tumours. Although there are some limitations of 3DPDVI, it seems that their application may be an effective tool in objective assessment of vascularity of fibroids. However further studies are required to consolidate the usage of 3DPDVI in clinical practice.

The role of levonorgestrel intrauterine systems in the treatment of symptomatic fibroids.

Uterine fibroids are considered to be the most frequently occurring tumours in females. The majority of fibroids do not require any treatment. When symptomatic, the major ailments include abnormal uterine bleeding, painful menstruation, pelvic pressure or pain, urinary problems, constipation, infertility, and recurrent pregnancy loss. Surgery remains a mainstay of symptomatic uterine fibroids therapy; however, minimally-invasive techniques and pharmacological management have become more available. The levonorgestrel intrauterine system (LNG-IUS) is a T-shaped device with a vertical stem containing a reservoir of levonorgestrel and is widely known for its contraception effect. Moreover, the non-contraceptive benefits of the LNG-IUS have been previously confirmed by numerous studies. LNG-IUS causes reduction of the duration and the amount of menstrual bleeding, with minimal side effects due to release of hormones at the targeted organ. Currently, results from systematic reviews show that LNG-IUS may be an effective and safe treatment for symptomatic uterine fibroids in premenopausal women. However, further studies are required to consolidate the usage of LNG-IUS in the treatment of symptomatic uterine fibroids.

The safety and tolerance of phytotherapies in menopausal medicine - a review of the literature.

Phytoestrogens are polyphenol, non-steroidal substances of plant origin, resembling 17ß-estradiol in structure. These substances can act as either agonists or antagonists of oestrogen receptors α and ß. Phytoestrogens are widely used to alleviate menopausal symptoms, such as hot flushes and night sweats. Most of the currently available products of plant origin registered to soften climacteric symptoms consist of extracts obtained from soy, red clover, or black cohosh. Non-hormonal phytotherapy is a new alternative for patients suffering from menopausal symptoms. Active ingredients such as PI 82-GC FEM extract do not show any direct hormonal mechanisms of action typical for oestrogens and phytoestrogens. There are concerns about the safety and tolerability of phytoestrogens. In this review we summarise the current literature regarding the clinical aspect of safety and tolerance of different phytotherapies used to relieve menopausal symptoms.

Minimally invasive procedures in the management of uterine fibroids.

Uterine fibroids are benign uterine tumors. In women during the reproductive period, uterine fibroids occur in about 25%, whereas after this time, they are observed in more than 40% of women. In the majority of women (about 20-50%), such tumors do not cause discomfort and do not require treatment. Asymptomatic uterine fibroids usually undergo only regular medical control, whereas symptomatic fibroids are an indication for treatment. Current treatment methods include surgical, pharmacological and minimally invasive treatment. Among the current commonly used methods, there are minimally invasive treatment options, which include Uterine Artery Embolization (UAE), Magnetic Resonance Guided Ultrasound Surgery (MRgFUS), MR-guided High Intensity Focused Ultrasound (MR-HIFU) and Laparoscopic Uterine Artery Occlusion (LUAO). The minimally invasive Ultrasound-guided High Intensity Focused Ultrasound method (US-HIFU) is new, but still experimental. The use of MRgFUS/MR-HIFU for the thermoablative treatment of fibroids was approved by the FDA (Food and Drug Administration) in 2004. As a minimally invasive method, it enables preservation of the uterus and eliminates the need for general anesthesia. LUAO is based on the use of the vascular clip, which is placed on the uterine artery at the level of the internal iliac artery. This procedure is performed bilaterally. The use of UAE in obstetrics and gynecology was first described in 1987 as an effective method in the treatment of hemorrhage, which allows avoiding surgical intervention and enables the uterus to be preserved. An appropriate qualification of patients is crucial for high clinical efficacy and prevention of complications after UAE. The candidates should be women with symptomatic uterine fibroids, without other pathologies within the pelvis, who do not plan to get pregnant in the future. The variety of uterine fibroids as for the location, size, and symptoms they can evoke, has enforced a very individual approach to each patient, to begin with observation and regular gynecological control, through a number of pharmacological and minimally invasive treatment methods, and ending with the removal of the uterus. It gives the doctors the tools, which, if used properly, can manage uterine fibroids and fulfil the expectations of the patient.

Elastography Improves the Diagnostic Accuracy of Sonography in Differentiating Endometrial Polyps and Submucosal Fibroids.

OBJECTIVES: To assess whether strain elastography may be used to visualize the different stiffness of endometrial polyps and submucosal fibroids. METHODS: We conducted a prospective monocentric single-operator study on diagnostic accuracy. Patients who qualified for hysteroscopy because of suspected endometrial polyps and submucosal fibroids were included. Before the procedure, all patients underwent routine sonographic and power Doppler examinations. Additionally, the stiffness of intrauterine lesions was assessed by strain elastography. The enhancement was adjusted to visualize hard myometrium and soft endometrium around the intrauterine lesion. Due to their histologic structure, we assumed that on strain elastography, endometrial polyps should appear as soft lesions, whereas submucosal fibroids should appear as hard lesions. Sonographic, power Doppler, and elastographic findings were verified by pathologic examinations after hysteroscopies. The diagnostic accuracy of sonography, power Doppler imaging, and strain elastography was compared by the McNemar test. RESULTS: Forty-seven patients were included and underwent hysteroscopy. In 29 cases, endometrial polyps were found, and in 18, submucosal fibroids were found. The diagnostic accuracy rates for B-mode sonography, power Doppler imaging, and strain elastography in distinguishing endometrial polyps and submucosal fibroids were 70.2%, 65.9%, and 89.4%, respectively. The proportion of correct findings was significantly higher for strain elastography than for B-mode sonography (P = .0265) and power Doppler imaging (P = .0153). CONCLUSIONS: Strain elastography complements sonography in differentiating intrauterine lesions. Strain elastography may be used to visualize the different stiffness of endometrial polyps and submucosal fibroids.

Unusual location of a plexiform neurofibroma in the fallopian tube: A case report.

It is rare for neurofibromatosis to occur in the female genital tract. We report a case of a plexiform neurofibroma in the left fallopian tube in a 50-year-old postmenopausal woman. The initial diagnosis was a pedunculated leiomyoma or a fallopian tube tumor. Laparotomy was performed and a solid mass approximately 90 x 60 x 40 mm in size was found in the left fallopian tube. Total abdominal hysterectomy and bilateral salpingo-oophorectomy with an appendectomy, lymphadenectomy and omentectomy was performed. The histopathological diagnosis was plexiform neurofibroma. Although neurofibromatosis may involve various gynecological structures, to the best of our knowledge, localized plexiform neurofibroma in the fallopian tube has not previously been reported. The presented case is the first report of clinical, ultrasound and histopathological findings in a fallopian tube neurofibroma. Neurofibroma is a neoplasm that should be taken into consideration when diagnosing pelvic masses.

Perioperative complications of gynecologic surgery in diabetic patients.

OBJECTIVES: The aim of the study was to estimate whether diabetes was an independent risk factor for perioperative complications in patients undergoing gynecologic surgery. MATERIAL AND METHODS: The study population consisted of 182 women (diabetics and controls) who underwent elective gynecologic surgery. Each patient without diabetes from the control group and matched for age and body mass index diabetic patient were admitted with the same gynecologic diagnosis, underwent the same gynecologic procedure, were operated on in the same operating room and were hospitalized within the same time interval. The following parameters of the perioperative period were compared between every matched pair of patients (diabetic vs. non-diabetic patient): number and characteristics of intra- and postoperative complications, length of postoperative hospitalization, decrease in hemoglobin level, increase in body temperature, and postoperative use of antibiotics. RESULTS: The study revealed no statistically significant differences between the diabetic patients and pair-matched controls in terms of the examined parameters of the perioperative period. CONCLUSIONS: Diabetes was not an independent risk factor for early postoperative complications after gynecologic procedures in the examined population. Good pre-operative glycemic control and strict cooperation of the diabetologist with the surgeon in the perioperative period resulted in reduction of the complication rate to the level typical for non-diabetic patients.

Genital psoriasis: a hidden multidisciplinary problem - a review of literature.

Genital psoriasis is a variety of autoimmune dermatological disease - psoriasis with relapsing-remitting course, which can have an onset in all age groups. It is most often diagnosed at an advanced stage. Genital psoriasis is considered an embar-rassing condition and is often misjudged as a sexually transmitted disease or allergic reaction due to low social awareness of the disease. The manifestations of genital psoriasis may differ from typical genital dermatoses and with symptoms such as itch, erythroderma and vaginal discharge may mimic other diseases at an early stage. The diagnosis and treatment of genital psoriasis may be difficult and often requires a multidisciplinary approach. The aim of this article is to present the literature review of genital psoriasis concentrating on the clinical presentation, treatment and influence on the quality of patients' life and sexual activity disorders.

The influence of uterine artery embolisation on ovarian reserve, fertility, and pregnancy outcomes - a review of literature.

Uterine fibroids are considered to be the most frequent female benign tumours. Fibroids affect mainly women of reproductive age. The most frequently reported signs and symptoms of fibroids include disturbances of the menstrual cycle such as heavy bleeding and painful menstruation, pelvic masses associated with pelvic pain, urinary problems or constipation, as well as infertility and recurrent pregnancy loss. The mainstay of fibroid treatment is still surgery. However, many patients seek alternative treatment options for fibroids, to preserve their uterus and fertility. One of the most important alternative treatment options for fibroids is uterine artery embolisation (UAE). However, there are some concerns that UAE may negatively influence ovarian function and even result in premature menopause. Moreover, the use of UAE in patients with future reproductive plans is still controversial, due to the possible pregnancy complications. The purpose of this review is to summarise the current knowledge regarding the possible influence of UAE on fertility, pregnancy outcome, and ovarian reserve.

Usefulness of elastography in predicting the outcome of Foley catheter labour induction.

BACKGROUND: Incorrect selection of women for labour induction may increase the risk of caesarean section and other postpartum and neonatal complications. It has been recently shown that elastography of the uterine cervix holds the potential to predict the outcome of pharmacological labour induction. There are no data on the usefulness of elastography in predicting the outcome of mechanical induction of labour. AIM: To assess the usefulness of elastographic cervical assessment in predicting the success of Foley catheter labour induction. MATERIALS AND METHODS: This prospective observational study included 39 pregnant women at term with an unfavourable cervix (Bishop score ≤ 6) suitable for Foley catheter labour induction. Before labour induction the following data were recorded: Bishop score, cervical length (measured by ultrasound) and the stiffness of cervical internal os, canal and external os assessed by elastography (elastography index - EI). Statistical relationships between pre-interventional assessment of the cervix and outcome of Foley catheter labour induction (successful induction, time to delivery and route of delivery) were analysed. RESULTS: EI's of internal cervical os and cervical canal were significantly lower (softer) in women with successful labour induction and vaginal delivery, while EI's of the external cervical os, Bishop score and cervix length were not significantly different. Time to vaginal delivery was significantly correlated with the EI's of internal cervical os, cervical canal and Bishop score, but not with EI's of the external cervical os and cervix length. CONCLUSION: Elastography has the potential to predict the outcome of Foley catheter labour induction.

Elastography for predicting preterm delivery in patients with short cervical length at 18-22 weeks of gestation: a prospective observational study.

OBJECTIVES: The aim of the study was to estimate the potential value of elastographic evaluation of the internal cervical os at 18-22 weeks of pregnancy in patients with short cervical length for prediction of preterm delivery (PTD). MATERIAL AND METHODS: This prospective observational study included 109 patients with cervical length of ≤ 25 mm at 18-22 weeks scan. Stiffness of the internal cervical os was assessed by elastography. Elastographic assessment of the internal os was performed using a color map: red (soft), yellow (medium soft), blue (medium hard), and purple (hard). If two colors were visible in the region of the internal os, the softer option was noted. The following outcome measures were analyzed: percentage of PTDs in various categories of elastographic cervical assessment, sensitivity specificity negative predictive value (NPV), and positive predictive value (PPV) of elastography in predicting PTDs. Additionally ROC curves were constructed for elastography and cervical length for predicting PTDs. RESULTS: Forty-five cases of PTDs (< 37 weeks of pregnancy) were found in the studied population. The number of PTDs was significantly higher in the red group, than in the blue and purple groups. The sensitivity specificity NPV and PPV for the assessment of both, red and yellow internal os for predicting preterm delivery were 82.2%, 75.0%, 84.0% and 72.5% respectively The cut-off value for elastography suggested inclusion of both, red and yellow (warm) colors as predictors of PTD. CONCLUSIONS: Elastographic evaluation of the internal cervical os at 18-22 weeks of pregnancy in patients with short cervical length may be useful in predicting PTD.

Evaluation of effectiveness of endovascular embolisation for the treatment of pelvic congestion syndrome--preliminary study.

OBJECTIVES: The Aim: The aim of the study was to evaluate the effectiveness, safety and clinical outcomes of endovascular embolisation of pelvic congestion syndrome (PCS). MATERIAL AND METHODS: This prospective, observational study carried out between January and May of 2014 encompassed 24 female patients aged 22-44 years (average - 31 years) diagnosed with PCS. Diagnosis of PCS was established by medical history physical examination, transvaginal Doppler ultrasound examination and confirmed by MRI. The patients were qualified for phlebography and ovarian vein embolization with 0.035" detachable coils and/or microcoils. Pelvic pain scores were assessed before and 3 months after the procedure with the visual analog scale (VAS; 0 - no pain, 10 - unbearable pain). RESULTS: Embolisation procedures were performed in 23 out of 24 patients. Nineteen patients underwent unilateral and 4 patients bilateral embolisation of the ovarian vein. In one case, safe and selective vessel catheterization was not possible due to the anatomical variant of venous flow. Nineteen patients underwent unilateral embolisation of the left ovarian vein. Four patients had the left and right ovarian veins embolized; in one of them, the internal iliac vein was additionally closed (the two-stage procedure). The technical success rate was 96%. Procedures lasted 23-78 minutes (32 minutes on average). An average of 40 ml of contrast was administered during the procedures. The total mean radiation dose at the reference point was 389 mGy (from 127 mGy to 1112 mGy). A decrease in pelvic pain intensity according to VAS was considered a clinical success. The median VAS pelvic pain score before the procedure was 8. Three months after the procedure median pelvic pain score decreased to 1 (p < 0.001). In two cases, the ovarian vein was injured and the contrast medium extravasated, which was clinically insignificant. In one case, a small injection site haematoma developed. CONCLUSION: Embolisation is a minimally invasive, effective and safe method of treatment for PCS. The cooperation between gynaecologists and interventional radiologists is essential for successful outcomes.

Pelvic organ prolapse in women: how is it diagnosed and treated currently?

The aim of the paper was to summarize the current opinions about the management of pelvic organ prolapse in women. Food and Drug Administration safety announcements from 2008 and 2011 triggered the discussion about the methods of treatment of pelvic organ prolapse and the used materials and a partial return to the methods which had been totally criticized before the implementation of meshes. The decrease in mesh usage is also observed. The studies did not demonstrate the prevalence of any particular surgical procedure. The amount of studies concerning the evaluation and the treatment of pelvic organ prolapse ensures that the quality of care provided to women with urogynecological problems is continuously increasing.
