Appearance of levator ani muscle subdivision defects on level III vaginal support structures in women with and without pelvic organ prolapse: an MRI study.

INTRODUCTION AND HYPOTHESIS: Injury of the levator ani muscle (LAM) is a significant risk factor for pelvic organ prolapse (POP). The puborectalis (PRM) and pubovisceral (PVM) subdivisions are level III vaginal support structures. The null hypothesis was that there is no significant difference in patterns of LAM subdivisions in healthy nulliparous women. Secondarily, we evaluated the presence of different LAM injury in a POP-symptomatic cohort. METHODS: This retrospective magnetic resonance imaging study included: 64 nulligravidae without any pelvic floor dysfunction (PFD) and 526 women of various parity with symptomatic POP. Primary outcome was PVM and PRM morphology on the axial planes: the attachment site on the pubic bone, and the visible separation/border between the PVM and PRM. The attachment was scored as "normal" or "abnormal". The "abnormal" attachment was divided in two types: "type I"-loss of the muscle substance, but preservation of the overall muscle architecture-and "type II"-muscle detachment from the pubic bone. RESULTS: The puboanal muscle (PAM) subdivision was evaluated as a representative part of the PVM. The PAM and PRM attachments and separation were distinguished in all asymptomatic nulliparae. PAM and PRM attachments did not significantly differ. POP group characteristics were parity 1.9 ± 0.8, instrumental delivery 5.6%, hysterectomy or POP surgery 60%, all Pelvic Organ Prolapse Quantification (POP-Q) stages, LAM defect 77.6% (PRM: 77.1%; PAM: 51.3%). Type I injuries were more frequent (PRM 54.7%; PAM 53.9%) compared with type II (PRM 29.4%; PAM 42.1%). CONCLUSIONS: A LAM defect was present in 77.6% of women with symptomatic POP. In PRM and PAM subdivisions type I injury was more frequent than type II.

A model for predicting unscheduled caesarean section in nulliparae.

OBJECTIVE: The objective of the study is to analyze the predictors of unplanned cesarean section in nulliparae. DESIGN: Prospective cohort study. SETTING: Institute for the Care of Mother and Child in Prague. METHODS: This study consisted of nulliparae giving birth between the 37th and 42nd weeks of singleton low-risk pregnancy, with the fetus in vertex position and without primary indication for CS. Selected prenatal and intranatal factors were analyzed in relation to acute CS due to a failure to progress in labor and/or fetal distress. Using logistic regression analysis (LR1-3) and the classification tree method (chi-square automatic interaction detector 1-2), five prediction models were tested. RESULTS: Of 3,728 nulliparae, 908 (24.4%) had an acute CS. All logistic regression models were comparable (receiver operating characteristic (ROC) 0.837-0.0881) and identified the occiput posterior position (OPP) of the fetus, maternal age, and epidural analgesia as the most influential risk factors. Spontaneous onset of labor, oxytocin administration, and maternal body height decreased are likely indicated for acute CS. The ability to predict a vaginal delivery was 95.7-96.3% and CS was 58.5-61.8%. The classification tree method (ROC 0.860-0.861) identified similar risk factors such as the OPP, peridural analgesia, and spontaneous onset of labor. The prediction abilities were similar at 94.5-96.4% for vaginal delivery and 64.6-59.0% for CS. CONCLUSION: OPP of the fetus was the strongest risk factor for the unsuccessful trial of vaginal labor.

First-trimester screening for preeclampsia.

DESIGN: Review article. SETTING: Department of Clinical Biochemistry, University Hospital Olomouc; Department of Obstetrics and Gynecology, Palacky University Olomouc, Faculty of Medicine and Dentistry, University Hospital Olomouc; The Institute for the Care of Mother and Child and 3rd Faculty of Medicine Charles University, Prague; G-CENTRUM Olomouc, Olomouc; Genetika Plzeň, Pilsen. Methods, results: Preeclampsia (PE) is a multisystem disorder complicating pregnancy. It is the leading cause of maternal and perinatal mortality and morbidity worldwide. Recent studies have shown that high-risk pregnant women may benefit from low-dose acetylsalicylic acid early therapy in prevention of the development of severe forms of the disease. The risk group of pregnant women should be identified in 11-13 gestational week for effective prevention. The only procedure validated in many studies for performing PE screening with sufficient diagnostic accuracy in the first trimester of pregnancy is given by The Fetal Medicine Foundation (FMF) and has been adopted and published in a new recommendation by The International Federation of Gynecology and Obstetrics (FIGO). CONCLUSION: This article summarizes the recent findings and recommendation for performing screening of preeclampsia in 1st trimester of pregnancy and how to prevent the development of severe forms of PE by low-dose acetylsalicylic acid therapy.

Laboratory options for risk assessment of pregnancy pathologies.

The most effective method of screening for chromosomal abnormalities and evaluating the risk of pregnancy pathologies in the first trimester is combined screening. The algorithm of screening is based on the combination of maternal age, measuring of the nuchal translucency and the fetal heart rate and analysis of the placental products of free ß-hCG and PAPP-A. For the screening of preeclampsia, placental growth factor (PlGF) is added. To distinguish between preeclampsia and other pathologies caused by placental dysfunction it is recommended to also extend the screening with selected immunological markers. We concluded that elevated biochemical and immunological markers can help to predict the threat of preeclampsia in the third trimester. Some markers can probably predict the development of particularly severe pathological conditions.

[MRI analysis of the musculo-fascial component of pelvic floor in woman before planned vaginal reconstruction procedur for symptomatic pelvic organ prolapse]. / Analýza stavu muskulo-fasciální slozky pánevního dna pomocí MRI u pacientek pred plánovaným vaginálním rekonstrukcním výkonem pro symptomatický sestup pánevního dna.

OBJECTIVE: The aim of the study is to analyse the musculo-fascial component of the pelvic floor in symptomatic group of woman with pelvic organ prolapse before planned vaginal reconstruction using synthetic vaginal mesh. DESIGN: Observational cohort study. SETTING: Department of Obstetrics and Gynaecology, Hospital in Frýdek-Místek; GONA Ltd, Prague; Institute for Care of Mother and Child, Prague; 3rd Faculty of Medicine CHU Prague. METHODOLOGY: The study involved 285 female volunteers (6 nulliparous, all other patients gave birth vaginally at least once) that in the period 2008-2015 before the planned reconstructive vaginal operations have undergone a comprehensive urogynaecology examination supplemented by magnetic resonance imaging (MRI) of the pelvic floor. Assessed was musculofascial component of the pelvic floor containing -musculus levator ani (MLA), endopelvic fascia (EF) and sacrouterine ligaments (SUL). MLA and EF were evaluated at two levels. The first level corresponds to the puborectalis muscle (evaluation of MRI trauma stage and avulsion), the second level correspondes to the iliococcygeus muscule (evaluation only avulsion injury to the muscle). RESULTS: Normal appereance of musculus puborectalis (level 1) was captured only in 25 (8.8) women. In 117 (41.1%) of women were present MRI minor trauma, 143 (50,2%) women were present with MRI major trauma. Avulsion of the muscle was captured in 85 cases (29.8%) at level 1 and in 165 cases (57.9%) in level 2. Preserved architecture of the EF was caught only 99 (34.7%) of the cases in level 1 and in 47 cases (16.5%) in level 2. Sacrouterine ligaments showed normal morphology in 100 cases (35.1%).Conslusion: Defects of musculofascial component of the pelvic floor is found frequently in women with symptomatic pelvic organ prolapse. Often a combination of defects MLA, EF and SUL are found. These comprehensive pelvic floor defects require careful urogynecological examination and planing operating methods with a view to minimizing the likelihood of recurrence of the descent. In indicated cases the use of the synthetic vaginal mesh is as a method of first choice.

[The results of five years follow-up prospective study of vaginal prolapse repaired by prolift total mesh surgery or sacrospinous fixation]. / Resení sestupu trí kompartmentu pomocí syntetického implantátu a sakrospinózní fixace: kohortová prospektivní studie s délkou follow-up peti let.

OBJECTIVE: The aim of the study is to compare the results of five years follow-up prospective study of vaginal prolapse repaired by prolift total mesh surgery or sacrospinous fixation. STUDY DESIGN: A single-center prospective, cohort study, in patients with defect grade II and more by POP-Q. SETTING: The Institute for the Care of Mather and Child; 3rd Medical Faculty Charles university, Prague. METHODS: Comparison of the preoperative state and the five years after the operation according POP Q, ICIQ-SF, PISQ 12, VAS. Comparison of intraoperative and postoperative complications. RESULTS: The study was attended by 142 patients; 75 patients underwent surgery Prolift Total and 67 patients sacrospinous fixation by Amreich Richter. On clinical examination at 5-year follow-up, we observed 15 (20.0%) case of anatomical failure in the Prolift group and 30 (44.8%) in the SSF group. Anatomic failure was defined clinically as Ba, C or Bp at the hymen or below. In assessing the overall condition before and five years after surgery using a VAS occurred in patients in the cohort Prolift Total decrease to 2.9 (± 1.9) from the original 7.8 (± 1.8). VAS in SSF group decreased after 5 years to 4.2 (± 2.7) of the original 7.8 (± 1.4). Values ICIQ-SF, analyzing the state of voiding PT group showed a decline from the original 6.7 (± 6.9) to 5.5 (± 5.3). A similar trend was evident even after the SSF. Parameters questionnaire PISQ-12 showed a positive increase from the original 28.6 (± 9.5) to 31.8 (± 7.9) points. PISQ-12 was improved from 28.7 (± 9.8) to 32.2 (± 7.5). CONCLUSION: Recurrences were observed more frequently in patients after sacrospinous fixation, while the quality of life questionnaires yielded comparable postoperative results. Quantity of intraoperative complications is low and both groups do not differ.

[Reconstruction of the posterior and central compartment with the Prolift Posterior: cohort study with a 5-year follow-up]. / Rekonstrukce defektu zadního a stredního kompartmentu pomocí kotveného implantátu Prolift Posterior: kohortová studie s petiletým follow-up.

OBJECTIVE: To analyse the results of the long-term prospective follow-up study of vaginal prolapse reconstructed using a Prolift Posterior. STUDY DESIGN: Prospective, cohort study. SETTING: Institute for the Care of Mother and Child, Prague. METHODS: Over a 5-year period (I/2006 - XII/2011) we prospectively followed a cohort of patients with posterior vaginal wall defect who underwent surgical reconstruction using a monofilament polypropylene implant Prolift Posterior (Gynecare, Ethicon, Inc., Piscataway, NJ, USA). Patients were invited for review at six weeks, three months, six months, 12 months and then yearly up to five years. Postoperative follow-up included the clinical examination and subjective evaluation using VAS, PISQ 12 and ICIQ SF. RESULTS: One hundred twenty-four women were included in the study, of which 14 (11.3%) had no prolapse surgery in their health history. There were no concomitant vaginal procedures such as hysterectomy or another implant surgery. The average operation time and blood loss were 64.25 min (min. 10, max. 205 min) and 115 ml (min. 10 ml, max. 1000 ml), respectively. Only one patient had a blood loss 1000 ml. There were no injuries of the urinary bladder or intestines during the needle insertion of the mesh. In the five-year period, the recurrence of posterior vaginal wall defect was observed in 4 cases (3.3%). The average time to the posterior vaginal wall recurrence prolapse was 19.5 months (min. 6, max. 36). De novo prolapse in the anterior compartment was observed in 25 patients (20.5%). CONCLUSION: In this prospective single centre study, we observed anatomical improvement in the implanted compartment with low recurrence rate. During five years follow-up period there was de novo anterior vaginal wall defect observed in 20.5% cases. The question of implant employment in urogynecology remain to be answered, however, our results show that implants have their position in reconstructive surgery.

[Retrospective analysis of monochorionic twin pregnancies born in the Institute for the Care of Mother and Child between 2012-2015]. / Analýza prípadu monochoriálních dvojcat porozených v Ústavu pro péci o matku a díte ve ctyrletém období (2012-2015).

OBJECTIVE: The purpose of this study was to describe monochorionic twin pregnancies and their complications, born between 24th and 37th week of gestation in the Institute for the Care of Mother and Child in years 2012-2015. DESIGN: Retrospective cohort. SETTING: The Institute for the Care of Mother and Child, Praha. METHODS: From 2012 to 2015 we observed 177 monochorionic twin pregnancies from which two or one viable fetuses were born, or both fetuses died in utero. RESULTS: From a total of 177 women, 12 (6.8%) gave birth before 26th week of gestation, between 26+0 - 27+6 four women (2.3%) gave birth, 37 women (20.9%) between 28+0 - 31+6, 84 women (47.8%) between 32+0 - 35+6 and after 36th week of gestation 40 women (22.6%) gave birth. Mean week of delivery was 33.8. Indications for termination of pregnancies were premature rupture of membranes (PPROM) in 11.9%, onset of spontaneus uterine contractions in 12.4% and in 53.3% other iatrogenic indication. 23.3% of pregnancies in our cohort were uncomplicated and terminated after 36th week of gestation. We performed caesarean section in 94.3%, in 5.7% patients gave birth vaginally. In vitro fertilization had 19.9% women, 80.1% conceived spontaneously. The age range of pregnant women in our cohort was 20-43, with median 32.3. Mean weight of bigger fetus was 2047.6 g (min. 520 g, max. 3530 g), mean weight of smaller fetus was 1799.5 g (min. 350 g, max. 2790 g). In 30 cases (16. 9%) we performed intrauterine intervetion. In 21/30 cases (11.9%) for TTTS diagnose, in 5/30 cases (2.8%) for congenital abnormalities or TRAP sequence and in 4/30 cases (2.2%) for sIUGR type III. The most frequent complication in our cohort was sIUGR (36 patients - 20.3%), TTTS (21 patients - 11.9%) and on the third place congenital abnormality or TRAP sequence (five patients - 2.8%) Nineteen patients gave birth to one viable fetus, in two cases both fetuses died in utero. In one case, in twin pair, one new-born died shortly after the birth - it had several congenital abnormalities and due to anhydramnion it was impossible to perform amnioinfusion and umbilical cord occlusion. After the birth it was given palliative care. CONCLUSION: The study brought data about specific risks in monochorionic twin pregnancies and suggests careful observation of women in fixed intervals and necessity of immediate referral to perinatal centre in case of any suspicious or pathological finding.

[The hypercholesterolemias in pregnancy: their etiology and diagnostic significance considerations]. / Hypercholesterolémie v tehotenství: úvahy o jejich etiologii a diagnostickém významu.

OBJECTIVE: Analysis of gestational hypercholesterolemia incidence in Prague population of healthy pregnant women. Diagnostic significance of non-cholesterol sterols as suitable markers of endogenous synthesis and intestinal absorption in etiology of gestational hypercholesterolemia. DESIGN: Retrospective study. PATIENTS AND METHODS: From 21 000 healthy pregnant women set of 84 patients with blood level of total cholesterol >7.0 mmol/l where noncholesterol sterols had been analyzed by use of GC/MS method on Finnigan MAT 120b. Lathosterol and desmosterol as markers of endogenous syntesis and campesterol and sitosterol as markers for intestinal absorbtion. Classical lipid parameters have been analyzed on Beckman Coulter and Cobas analyzators. RESULTS: The median of total cholesterol values in the set of 21 000 healthy pregnant women - 6,8 mmol/l was observed; median of LDLCh - 4.6 mmol/l and HDLCh - 2.2 mmol/l. The frequency of hypercholesterolemia values > 8.0 mmol/l 1:132 (!) was observed. The average values were for lathosterol 7.8 ± 1.7 µmol/l; desmosterol 4.7 ± 0.9 µmol/l; campesterol 9.8 ± 2.6 µmol/l; sitosterol 9.6 ± 3.8 µmol/l. The correlations of lathosterol with total cholesterol r = 0.524 as well as with non-HDLCh r = 0.35 and LDLCh r = 0.36 were observed. In campesterol or sitosterol as well as HDLCh or TAG no significant correlations have been observed. DISCUSSION: Pilot study for gestational hypercholesterolemias in Czech population of healthy pregnant women proved the high frequency of increased levels of total cholesterol (> 8.0 mmol/l) 1:132. Increased levels of lathosterol values could explain the hypercholesterolemia in pregnancy as result of higher endogene synthesis of cholesterol. CONCLUSION: Relatively high frequency of hypercholesterolemia in pregnancy is caused according to our findings by increased endogenous synthesis of cholesterol via lathosterol. The highly increased values of cholesterolemia during pregnancy could be efectivelly used for detection and after ending of lactation period for further differential diagnostic and treatment of previously undiagnosed familial hypercholesterolemias.

[Measurement of gestational sac volume in the first trimester of pregnancy]. / Merení objemu gestacního vácku v I. trimestru gestace.

OBJECTIVE: The aim of our study was to measure the volume of gestational sac and amniotic sac in physiological pregnancies and missed abortion. We wanted to create nomograms for individual weeks of gestation. DESIGN: Retrospective cohort study. SETTING: Institute for the Care of Mother and Child, Prague. METHODS: The study randomized 413 women after spontaneous conception. The patients were divided into two groups: women with physiological pregnancy and childbirth in the period (374), and women with pregnancy terminated by missed abortion. Both groups were performed measurement volume of gestational and amniotic sac in the first trimester of pregnancy. Analysis was performed using 4D View software applications, and volume calculations were performed using VOCAL (Virtual Organ Computer Aided anaLysis). RESULTS: We have created the first in the Czech Republic nomograms volumes of gestational and amniotic sac in physiological pregnancies and missed abortion. We performed a correlation between the size of gestational sac and prosperity pregnancy. CONCLUSION: In our study we found no correlation between the volume of gestational sac and the development of the pregnancy.

[Intrauterine fetal death syndrome: analysis of cases from 2008 to 2012 in Institute for the care of mother and child]. / Syndrom intrauterinního úmrtí plodu: analýza souboru za období 2008-2012 v Ústavu pro péci o matku díte

OBJECTIVE: We made an analysis of number of intrauterine fetal deaths in our institute, it's causes, risk factors and patient's main complaints. METHODS: Retrospective study of all intrauterine fetal deaths in Institute for the care of mother and child in years 2008-2012. RESULTS: We had 60 cases of intrauterine fetal death from 2008 to 2012 which represented 2.4 of all deliveries (24884). The examination started in 45% of cases due to information about decreased fetal movements, 28.3% was diagnosed during regular visit, 13.3% came for contractions, 10% because of PPROM and 3.3% due to vaginal bleeding. In 58.3% we used induction of delivery, in 10% delivery started spontaneously and in 31.7% a caesarean section was performed. CONCLUSION: Decrease in fetal movements was the most frequent complaint of our patients. Spontaneously delivered 68.3% patients, caesarean section was indicated in twins, due to maternal diseases or from vital indication. In 70% of cases we approved the cause of intrauterine fetal death. Mostly umbilical cord or placental abnormalities were present.

[Nocturia, incidence, ethiology, diagnostics]. / Epidemiologie, etiologie a diagnostika nykturie.

Nocturia is the complaint that the individual has to wake at night one or more times to void, according to the International Continence Society definition from the ICS Standardisation of Terminology Report 2002. As the nocturia definition is complicated there are also other slightly modified definitions. It is currently not absolutely clear if prevalence or incidence is more important for epidemiology evaluation of nocturia. Nocturia is a variable symptom and its presence in individuals is reversible therefore it is very difficult to obtain reliable incidence data. Nocturia prevalence varies remarkably in different studies according to evaluation methodology, nocturia definition, methods of data collection and characteristics of evaluated population. There are not enough studies, especially demographic ones, evaluating lower urinary tract symptoms and/or nocturia in males and females. There is relatively large number of comparative studies confirming strong correlation between aging and prevalence of nocturia. Prevalence of two or more voids per night in individuals in their twenties varies between 5-15 %, it progresses with age, and in the seventh decade of life ranges between 35-50 %. Prevalence evaluated by gender is higher among younger women compared to older women and older men compared to younger men. Currently there are only limited sources of data regarding nocturia incidence. Incidence of nocturia (two or more voids per night) in a population older than 60 years is 213 new cases/1000 persons/1 year in two year observation. Incidence of two or more voids per night is 75 new cases/1000 male/1 year in five year observation and 126 new cases/1000 male/1 year in ten year observation in male population. Incidence of nocturia rises significantly with age. Incidence of two or more voids per night increases by 2,7 % in the population of women after child birth during 5 year follow up and by 5,9 % during 12 year follow up. Incidence of nocturia newly diagnosed in a pregnancy drops down by 98% in 3 month after the child birth. The incidence data indicate that incidence of nocturia rises with age and probability of nocturia relief decreases with age. Incidence of mild nocturia is higher compared to incidence of severe nocturia and significant relief of nocturia in women after child birth is very inconsistent compared to increase of other lower urinary tract symptoms. Ethiology of nocturia might be polyuria, nocturnal polyuria or reduced bladder capacity. Nocturia and its ethiology can be determined in most cases with simple and commonly used investigative methods on the out-patients bases. The diagnostic algorithm should lead to verification of nocturia and identifying its cause because treatment of nocturia differs remarkably according to the etiology.

[Doctors specialty training in obstetrics and gynecology at university medical schools: 2012-2013]. / Specializacní vzdelávání v gynekologii a porodnictví na lékarských fakultách: 2012-2013.

OBJECTIVE: The paper addresses transfer of doctors specialty training from the national Institute of postgraduate medical education (IPVZ) to University Medical Schools (UMS) with the special focus to Obstetrics and Gynecology (OG). METHODS: The National Specialty Board (NSB) has been established. NSB tasks include definition of inclusion criteria and process of specialty choice at UMS. In OG specialty there are defined mid-term and final postgraduate training courses and other requirements for final specialty exam (FSE) - in particular trainees scientific work and surgery done with the supervision of NTB member. The system of FSE, its content, application, reimbursement and mechanisms are described in details. RESULTS: In the whole country in 2012 there have been done 864 FSE in all basic medical specialties, which took place at seven UMS. Autumn semester terms has been utilized significantly more than spring terms (57% vs. 43%). There have been differences in the numbers of specialties and also numbers of candidates in each specialty among different UMS. In total 94% of applicants succeed in the FSE. In 2012 within OG specialty training there has been held 56 FSE - 24 exams on five UMS in spring term and 32 (57%) exams only on two UMS in autumn term. In the spring 2013 FSE were organized on 1st LF UK in Prague with 23 applicants, from which 22 successfully passed. During autumn 2013 the FSE in OG will be held on LF UP in Olomouc with 44 applicants for final postgraduate training course and 39 candidates for FSE. CONCLUSION: Within OG specialty the transfer of doctors specialty training from IPVZ to UMS has been successfully managed. The NSB in OG specialty closely cooperates with past IPVZ and the Accreditation Commission of the Czech Ministry of Health. Thus continuity, quality and continuous enhancement of specialty training program in OG in Czech Republic is assured.

[Nocturnal polyuria, treatment with desmopressin]. / Lécba nocní polyurie desmopresinem.

UNLABELLED: Nonpharmacologic and especially pharmacologic treatment options are available for nocturnal polyuria. Desmopressin represents the basis of pharmacologic treatment. Desmopressin acetate is a synthetic analogue of arginine vasopressin with high affinity to V2 receptors with antidiuretic effect. It is the only medicament currently registered for antidiuretic treatment. Desmopressin has not any relevant affinity to V1 receptors, and therefore there is no hypertensive effect in contrary to natural vasopressin. Desmopressin use before a bedtime leads to reduced production of urine during a sleep, therefore time between desires to void is prolonged and number of nocturia is reduced. Clinical effect, in a meaning of reduced urine production and increased osmolality of urine, lasts approximately 8-12 hours. In the treatment of nocturnal polyuria desmopressin is used orally one hour before a bedtime. It is essential to titrate an ideal dose, the initial dose is 60 µg of MELT formula (fast melting oral formulation) and it can be increased according to the clinical effect up to the maximal recommended daily dose 240 µg. Patients treated with desmopressin should cut down a fluid intake 1 hour before and 8 hours after the use of desmopressin. Total number of adverse events connected withdesmopressin treatment in clinical studies was higher compared to placebo but the side effects were mostly mild. The most common adverse events were headaches, nausea, diarrhoea, abdominal pain, dry mouth and hyponatremia both in the short-term and long-term clinical trials. Hyponatremia was observed mainly in patients over 65 year of age. Therefore treatment with desmopressin should not be commended in patients over 65 year of age without close monitoring of the natrium level in serum and all patients should be informed about the first symptoms of hyponatremia - headache, nausea and insomnia. According to Evidence Based Medicine, the level of evidence for treatment of nocturnal polyuria with desmopressin is 1b and the grade of recommendation for treatment is A. KEYWORDS: nocturnal polyuria - treatment - desmopressin.

Immunological and biochemical markers in preeclampsia.

A basic precondition for the development of preeclampsia is the presence of placental trophoblast cells in the maternal blood circulation. On the other hand, while trophoblast cells are present in the blood of all pregnant women, preeclampsia occurs in only 2-5% of them. Evidently, other factors play a crucial role. The aim of this study was to compare a set of selected immunological factors (anti-cardiolipin autoantibodies, trophoblast-induced cell-mediated immunity, C3 and C4 complement components) and biochemical factors (serum immunoglobulins IgA, IgG, IgM) among three groups of women with uncomplicated pregnancy, gestational hypertension, or preeclampsia. Blood samples were taken 2-12h before delivery. In the preeclampsia group, there was a significantly higher number of women positive for anti-cardiolipin autoantibodies, trophoblast-induced cell-mediated immunity was elevated, serum IgG was elevated and C4 complement component was reduced. We conclude that both elevated autoimmune reactivity and the higher immune reactivity to trophoblast may contribute to the onset of preeclampsia.

[Peripartal life-threatening hemorrhage - interdisciplinary consensus opinion]. / Peripartální zivot ohrozující krvácení - mezioborové konsenzuální stanovisko.

22 experts from the fields of gynecology and obstetrics, anesthesiology and resuscitation, intensive care, hematology and transfusion medicine has developed recommendations for diagnosis and procedure for life-threatening peripartum haemorrhage, which is still one of the most common causes of maternal mortality in childbirth. This guidelines, which is valid for the Czech Republic, supported by a total of 10 professional medical societies. There are based on new knowledge applicable at this time and is focused mainly on eliminating the most common causes of bleeding during delivery and prevention of haemorrhagic shock.

[The role of three-dimensional ultrasonography in assisted reproduction]. / Vyuzití a význam 3D ultrasonografického vysetrení v asistované reprodukci.

OBJECTIVE: Clarifying the role of three-dimensional transvaginal sonography in diagnosis sterility and assisted reproduction treatment. DESIGN: Review. SETTING: Institute for the Care of Mother and Child, Department of IVF, Charles University, Prague. METHODS: Study of current literature. SUMMARY: With arrised frequency of ovarian, uterus and another pelvic patologies remains the three-dimensional transvaginal sonography in diagnosis of sterility women very actual in the fields of reproductive medicine. Actually the assessment of ovarian reserve belong to the essentials investigations in the diagnosis of primary and secondary sterility at this time. The advance in the three-dimensional transvaginal sonography allows to assess the endometrial volume, echogenity, endometrial vascularity and endometrial receptivity. There is a significant importance of 3D power Doppler angiography by measurement of folicular and ovarian vascularity with three indices (VI, FI, VFI) and provides the calculation of ovarian vascularity from the volume. New Sono-Automatic Volume Calculation (Sono-AVC) software that identifies and quantifies hypoechoic regions within a three-dimensional dataset and provides automatic estimation of their absolute dimensions, mean diameter and volume. An unlimited number of volumes can theoretically be quantified, which makes it an ideal tool for assessment of the ovarian volume and the antral follicle count (AFC) in women undergoing controlled ovarian stimulation.

Malignant changes in adenomyosis in patients with endometrioid adenocarcinoma.

OBJECTIVE: The aim of our retrospective study was to evaluate pathological changes in adenomyotic foci in hysterectomy specimens, and point out a possible mechanism of carcinogenesis in adenomyotic foci inside the myometrium. METHODS: Retrospective analysis of clinical data; 219 patients were operated at our departments from 2003-2008 with the diagnosis of early endometrial cancer. Standard staging operation was used in all cases and all hysterectomy specimens were afterwards routinely analyzed. RESULTS: Adenomyosis was found in 88 of a total of 219 hysterectomy specimens, while 205 of these 219 were affected by endometrioid adenocarcinoma, ten with clear cell carcinoma and four with papillary serous carcinoma. Within these subgroups adenomyosis was documented in 87 of 205 specimens with endometrioid adenocarcinoma (42.4%) and in one specimen of ten with clear cell carcinoma (2.2%), all found in the eutopic endometrium. All cases of malignant changes (n = 6) in adenomyosis were found exclusively with coexisting endometrioid adenocarcinoma: adenocarcinoma in adenomyosis was well or moderately differentiated in five cases, and poorly differentiated in just one case. Differentiation of the tumor in adenomyosis correlated with differentiation of the eutopic endometrial cancer in 50%. Hyperplastic changes like benign glandular hyperplasia, or atypical complex hyperplasia (ACH) were identified simultaneously in all cancer-positive adenomyotic foci. CONCLUSION: Malignant changes in adenomyosis were present in 6.8% of patients with endometrial cancer. All malignancy-positive cases of adenomyosis were associated with endometrioid adenocarcinoma of the eutopic endometrium. Interestingly, in all these cases, different stages of hyperplastic changes were also simultaneously identified. This observation suggests a similar pathway of carcinogenesis in adenomyosis as is known in estrogen-responsive endometrial cancer type I.

[Diagnosis and management in women with lower urinary tract symptoms (LUTS) after burch colposuspension]. / Management mikcních obtízí u pacientek po antiinkontinentním chirurgickém výkonu bez vyuzití syntetického materiálu na dolních cestách mocových.

OBJECTIVE: To demonstrate the significance of introital ultrasound of the lower urinary tract in the diagnostic algorithm in patients with lower urinary tract symptoms (LUTS) after Burch colposuspension. METHODS: Twenty six women with voiding dysfunction directly associated with prior anti-incontinence surgery (Burch colposuspension) were included in the study (Group A). The control group (Group B) consisted of twenty eight women after Burch colposuspension with a good clinical result without LUTS. Introital ultrasound was performed at rest and at maximum voluntary contraction to measure the monitored parameters (angle alpha: the inclination angle of the urethra, angle beta: the posterior urethrovesical angle, angle gamma: the angle between the axis of the symphysis and the line segment connecting the region of the internal urethral orifice and the lower margin of the symphysis, distance H: the distance between the internal urethral orifice and the horizontal axis running through the bottom edge of the symphysis, distance p: the distance between the internal urethral orifice and the lower margin of the symphysis). RESULTS: Significant differences were found in bladder neck position and mobility between those women with LUTS and control group. At a 5% confidence interval, both groups differ in mean values of the angles alpha, beta a gamma, and in the mean values of segments p and H on straining. Ventral displacement of the bladder neck (characterized by angles alpha and gamma) at rest and during straining was present in all women in group A. The difference was statistically significant (p=0,001). Angle beta also demonstrates abnormal position and minimal mobility of the bladder neck in group A. As a result of bladder neck disclocation in the ventral direction, at rest, this parameter shows significantly lower values in comparison with group B. This difference is more apparent on Valsalva, where as a result of minimal mobility of the bladder neck. This parameter has even lower values in group A in comparison with group B. The bladder neck in patients with LUTS after Burch colposuspension shows not only ventral displacement of the bladder neck but also a significant reduction in dorsocaudal movement during straining. CONCLUSION: In women with LUTS after Burch colposuspension, atypical changes in the position and mobility of urethra can be demonstrated when compared with women who underwent successful surgery for incontinence.

[Quiscent trophoblastic disease]. / Neinvazivní trofoblastická nemoc.

TYPE OF STUDY: Case report. SETTING: Center for trophoblastic disease in Czech Republic, Institute for care of mother and child, 3rd Faculty of Medicine of Charles University Prague. METHODS: The autors present a case of quiscent trophoblastic disease diagnosed at 27 years old primipara, secundigravida after previous molar pregnancy. The patient had low levels of serum hCG present for more than 18 months after the termination of pregnancy. After this period there was a malignant transformation associated with rapid elevation of hCG levels with need for chemotherapy which was succesfully completed. CONCLUSION: Quiscent (dormant, noninvasive) trophoblastic disease is a recently described unit defined by low levels of hCG present in patients serum and urine samples without any evidence of trophoblastic tumour or other source of hCG production. Quiscent trophoblastic disease is associated with high risk of malignant transformation.
