Does ethnicity have an effect on fetal behavior? A comparison of Asian and Caucasian populations.

AIM: This study aimed to evaluate the ethnic difference in fetal behavior between Asian and Caucasian populations. METHODS: Fetal behavior was assesed by Kurjak's antenatal neurodevelopmental test (KANET) using four-dimensional (4D) ultrasound between 28 and 38 weeks of gestation. Eighty-nine Japanese (representative of Asians) and seventy-eight Croatian (representative of Caucasians) pregnant women were studied. The total value of KANET score and values of each parameter (eight parameters) were compared. RESULTS: The total KANET score was normal in both populations, but there was a significant difference in total KANET scores between Japanese (median, 14; range, 10-16) and Croatian fetuses (median, 12; range, 10-15) (P<0.0001). When individual KANET parameters were compared, we found significant differences in four fetal movements (isolated head anteflexion, isolated eye blinking, facial alteration or mouth opening, and isolated leg movement). No significant differences were noted in the four other parameters (cranial suture and head circumference, isolated hand movement or hand to face movements, fingers movements, and gestalt of general movements). CONCLUSION: Our results suggest that ethnicity should be considered when evaluating fetal behavior, especially during assessment of fetal facial expressions. Although there was a difference in the total KANET score between Japanese and Croatian populations, all the scores in both groups were within normal range. Our results indicate that ethnical differences in fetal behaviour do not affect the total KANET score, but close follow-up should be continued in some borderline cases.

SPONTANEOUS HETEROTOPIC, ECTOPIC CERVICAL AND ECTOPIC TUBAL PREGNANCY - EVER PRESENT DIAGNOSTIC DIFFICULTY: THREE CASE REPORTS.

The incidence of heterotopic/ectopic pregnancy in recent times has increased partly due to the increase in assisted reproductive technologies, whereas such medical cases and cervical pregnancy in particular are extremely rare with spontaneous conception. We report on three patients referred to our department in one week: one patient each with spontaneous heterotopic pregnancy, cervical pregnancy and tubal pregnancy. All of them had conceived spontaneously and were properly diagnosed and treated, however, additional care is needed in diagnosing and managing the potentially fatal consequences of ectopic pregnancy if not recognized early and managed properly, despite its low incidence.

Diagnosis and counseling of thanatophoric dysplasia with four-dimensional ultrasound.

Thanatophoric dysplasia is a severe skeletal disorder with estimated frequency of 0.2-0.5 per 10,000 births. Affected infants die shortly after birth. The diagnosis of thanatophoric dysplasia can be made by two-dimensional ultrasound but the perception of these images is very difficult for the patients. The use of four-dimensional real time ultrasound gives the physician the possibility to discuss and counsel the patients with images that are more understandable to the general public.

Extremely large breast abscess in a breastfeeding mother.

Puerperal mastitis often occurs in younger primiparous women. Most cases occur between 3 and 8 weeks postpartum. If mastitis results in the formation of a breast abscess, surgical drainage or needle aspiration is most commonly performed. We report a case of an extremely large breast abscess in a primiparous 20-year-old woman, which presented 6 weeks postpartum. Surgical incision and evacuation of 2 liters of exudate were performed, and intravenous antibiotics therapy was administered. On the sixth day after incision, we secondarily closed the wound. Examination after 3 months showed symmetrical breasts with a small scar in the incision area of the right breast. A high degree of suspicion and adequate diagnostic procedures are essential to avoid delay in the treatment of mastitis and breast abscess and thereby prevent unnecessary surgical treatment.

[Acute abdomen two days after vaginal birth after cesarean section]. / Akutni abdomen dva dana nakon rodnickog porodaja poslije prethodnoga carskog reza.

A case is presented of puerperal acute abdomen with diffuse peritonitis and paralytic ileus two days after unnoticed complete uterine rupture after VBAC (vaginal birth after cesarean section) and uterine cavity obstetric examination. Explorative laparotomy, intestinal adhesiolysis, uterine revision and sutures, abdominal lavage and drainage were performed. The operation was followed by successful recovery and intact fertility. Medical and forensic aspects are discussed.

Neurobehavioral continuity from fetus to neonate.

Neurobehavior represents development of the central nervous system (CNS). Fetuses and newborns exhibit a large number of endogenously generated motor patterns, among which general movements are often investigated pre- and post-natally. Spontaneous activity is probably a more sensitive indicator of brain dysfunction than reactivity to sensory stimuli while testing reflexes. Nutritional stress at critical times during fetal development can have persistent and potentially irreversible effects particularly on brain growth and function. Unfavorable intrauterine environment can affect adversely brain growth. All endogenously generated movement patterns from un-stimulated CNS might be observed as early as from the seven to eight weeks' gestation, with a rich repertoire of movements within the next two or three weeks, continuing for five to six months postnatally. It is still uncertain whether a new scoring system for prenatal neurological assessment will be adequate for the distinction between normal and abnormal fetuses in low-risk pregnancies. The continuity of behavioral patterns from prenatal to postnatal life might answer these intriguing questions.

Prenatal and postnatal neurological evaluation of a fetus and newborn from pregnancy complicated with IUGR and fetal hypoxemia.

In this case report, we present prenatal and postnatal neurological evaluation of a fetus and newborn from pregnancy complicated with intrauterine growth restriction, fetal hypoxemia, and preterm labor. Despite unfavorable intrauterine conditions, this premature infant showed normal early neurological development that was verified not only by postnatal tests but also with a new prenatal neurological screening test.

The comparison of fetal behavior in high risk and normal pregnancies assessed by four dimensional ultrasound.

OBJECTIVE: We compared fetal behavior (FB) in high risk and normal pregnancies using four dimensional ultrasound (4DUS). METHODS: For assessment of FB in high risk and normal pregnancies, we used a scoring system of Kurjak's antenatal neurological test (KANET). The newborns were assessed by a postnatal neurological test, Amiel-Tison neurological assessment at term (ATNAT). The scores of KANET in high risk (N=116) and in normal pregnancies (N=110) were compared. After delivery, the results of KANET from both groups were compared with ATNAT test. RESULTS: There was a statistically significant difference between group of high risk and normal pregnancies, for 8 out of 10 parameters in KANET: isolated anteflection of the head, eye blinking, facial expressions, mouth movements, isolated hand movement, hand to face movement, fist and finger movements, general movements. There was no difference for cranial sutures and isolated leg movements. Comparison of KANET and ATNAT showed statistically significant, moderate correlation between the two tests, which means that the neuropediatric exam (ATNAT) confirmed the prenatal 4DUS finding (KANET). CONCLUSION: The difference of FB between the high risk and normal pregnancies was evident. These preliminary results are promising but further studies have to be done before the test could be recommended for wider clinical practice.

The potential of 4D sonography in the assessment of fetal neurobehavior--multicentric study in high-risk pregnancies.

OBJECTIVE: An evolving challenge for obstetrician is to better define normal and abnormal fetal neurological function in utero in order to better predict antenatally which fetuses are at risk for adverse neurological outcome. PATIENTS AND METHODS: Prenatal neurological assessment in high-risk fetuses using four-dimensional ultrasound applying the recently developed Kurjak antenatal neurodevelopmental test (KANET). Postnatal neurological assessment was performed using Amiel Tison's neurological assessment at term (ATNAT) for all live-borns and general movement (GM) assessment for those with borderline and abnormal ATNAT. RESULTS: Inclusion criteria were met by 288 pregnant women in four centers of whom 266 gave birth to a live-born baby. It was revealed that 234 fetuses were neurologically normal, 7 abnormal and 25 borderline. Out of 7 abnormal fetuses ATNAT was borderline in 5 and abnormal in 2, whereas GM assessment was abnormal in 5 and definitely abnormal in 2. Out of 25 KANET borderline fetuses, ATNAT was normal in 7, borderline in 17 and abnormal in 1, whereas the GM assessment was as follows: normal optimal in 4, normal suboptimal in 20, and abnormal in 1. In summary, out of 32 borderline and abnormal fetuses ATNAT was normal in 7, borderline in 22 and abnormal in 3; GM assessment was normal optimal in 4, normal suboptimal in 20, abnormal in 6 and definitely abnormal in 2. CONCLUSION: The sonographic test requires further studies before being recommended for wider clinical practice.

New scoring system for fetal neurobehavior assessed by three- and four-dimensional sonography.

AIM: To produce a new scoring system for fetal neurobehavior based on prenatal assessment by 3D/4D sonography. We identified severely brain damaged infants and those with optimal neurological findings and compared fetal with neonatal findings. RESULTS: The new scoring system was retrospectively applied in a group of 100 low-risk pregnancies. After delivery, postnatal neurological assessment was performed, and all neonates assessed as normal reached a score between 14 and 20, which we assumed to be a score of optimal neurological development. Subsequently, the same scoring system was applied in the group of 120 high-risk pregnancies in which, based on postnatal neurological findings, three subgroups of newborns were found: normal, mildly or moderately abnormal, and abnormal. Normal neonates had a prenatal score between 14 and 20, mildly or moderately abnormal neonates had a prenatal score of 5-13, whereas those infants who were assigned as neurologically abnormal had a prenatal score from 0-5. CONCLUSION: A new scoring system for the assessment of neurological status for antenatal application is proposed, similar to the neonatal optimality test of Amiel-Tison. This preliminary work may help in detecting fetal brain and neurodevelopmental alterations due to in utero brain impairment.

[Dillema about the method of delivery for the fetus in breech presentation]. / Dvojbe o nacinu porodaja ploda u stavu zatkom.

The management of preterm and term delivery of fetus in breech presentation is one of the most disputable issues in modern obstetric practice. Several years ago, one of the biggest randomized controlled studies in obstetrics, Term Breech Trial (TBT), tried to set up guidelines and resolve the question of the best method to deliver the fetus at term in breech presentation. The results of this study have shown that the policy of planned cesarean section reduces the risk of short-term adverse perinatal outcome, compared with the policy of planned vaginal birth. Many perinatal centers have accepted the recommendations from this study and different obstetric associations have implemented these results in their guidelines. On the other hand, TBT had some limitations, especially those connected with the impossibility of regular and objective comparison of these two methods of delivery. In addition, the same group of authors did not find differences in long-term outcomes between the planned cesarean section and vaginal delivery. Although the rate of planned cesarean section has increased following the publication of TBT, selective vaginal breech delivery is still very successfully used in the centers where doctors have the possibility to obtain experience in vaginal breech deliveries. The most common method of reduce the noncephalic presentation is external cephalic version at term. It reduces the incidence of noncephalic presentations at labor, thus reducing the number of cesarean sections as well. At this moment, there is not enough evidence to support cesarean section as the method of choice for delivery of preterm and term breech, having in mind obstetric indications and criteria. The decision whether to deliver vaginally or by cesarean section should be individual for each pregnant woman.

Is sonographic assessment of cervical length better than digital examination in screening for preterm delivery in a low-risk population?

BACKGROUND: This randomized controlled trial compared the diagnostic accuracy of the sonographic assessment of cervical length and clinical digital examination of the cervix in the second trimester regarding the prediction of preterm delivery in a low-risk population. METHODS: In total, 282 unselected, asymptomatic women with singleton pregnancy randomly underwent sonographic cervical length measurement (study group, n=138) or clinical digital examination (control group, n=144) in the second trimester. In the study group cervical length or=95th percentile (>or=4) for our population was defined as high. The primary outcome measure was the diagnostic accuracy of both tests regarding the prediction of preterm delivery (<37 weeks). RESULTS: Shortened cervical length was found in 6/138 (4.3%) women whereas the high Bishop score was found in 17/144 (11.8%) (p=0.038, Fisher's exact test). The incidence of preterm delivery was 5.7% (16/282). Regarding the prediction of preterm delivery, shortened cervical length and high Bishop score had sensitivity 57.1% versus 33.3% and positive predictive value 66.7% versus 17.6%. Shortened cervical length in comparison with high Bishop score had 12-fold higher positive likelihood ratio for preterm delivery in a low-risk population (37.4; 95%CI [8.2-170.7] versus 3.2; 95%CI [1.1-9.2]). CONCLUSION: Sonographic assessment of cervical length has better diagnostic accuracy in the prediction of preterm delivery compared to digital examination in a low-risk population.

Prevalence of scoliosis in school-children from Mostar, Bosnia and Herzegovina.

In the school-year 2002/2003 a prospective epidemiological study was performed with the aim of evaluating the prevalence and distribution of scoliosis in the population of schoolchildren from Mostar, Bosnia and Herzegovina. The general check-up of primary-school children covered a total of 2,517 children aged 7-14. The children in which at least one positive symptom of scoliosis was found were directed to undergo orthopedic examination and--if indicated--radiography. Incorrect posture was noted in 33.4% of children, and 11.8% of children were sent to orthopedic specialist examination. The prevalence of structural scoliosis amounted to 3.1%, with the spine curvature threshold being 10 degrees. In eight children (0.32%; 1 boy and 7 girls) a curvature of 20 degrees or more was diagnosed. The most common type of curvature was the thoracal (39%) and the thoraco-lumbar (39%) while 14 children had a double curvature (17.8%). A scoliosis was detected due to here performed check-up in 83.5% of children with scoliosis. No case of serious spine deformity (45 degree or more) was recorded, due to regular general check-ups taking place biannually in this population.

Qualitative glandular cervical score as a potential new sonomorphological parameter in screening for preterm delivery.

This study compared diagnostic accuracy of sonographic assessment of cervical length (CL) and qualitative glandular cervical score (QGCS), in the second trimester regarding the prediction of preterm delivery (PTD) in the low-risk population. Cervical length < or = fifth percentile for our population was defined as shortened. The parameters evaluated in QGCS were: cervical mucus area and deepest invasion of cervical glands, and score < or = fifth percentile for our population was defined as low. Shortened CL was found in 6.1% whereas the low QGCS was found in 5.5%. The incidence of PTD < 34 completed wk was 2.1%, and between 34 to 37 wk it was 3%. Low QGCS in comparison with shortened CL had twofold higher likelihood ratio (LR) (23; 95% CI [12 to 43] versus 11; 95% CI [5 to 25]) for PTD < 34 completed wk and fourfold higher LR (12; 95%CI [5 to 28] versus 3; 95% CI [1 to 13]) for PTD between 34 to 37 wk. Low QGCS has the same if not better accuracy in comparison with shortened CL regarding the prediction of PTD in the low-risk population.

Ritodrine in oral maintenance of tocolysis after active preterm labor: randomized controlled trial.

AIM: To assess the efficacy of oral ritodrine in the form of sustained-release capsules for maintenance of uterine quiescence after successful treatment of threatened preterm labor. METHODS: We randomized 120 women with singleton pregnancy who were successfully treated for threatened preterm labor before 34 completed weeks to receive either maintenance tocolysis with two 40 mg ritodrine sustained release capsules three times a day (study group, n=62) or no treatment (control group, n=58) for three days. The primary outcome measure was the recurrent episode of threatened preterm labor within 72 hours, which was defined as regular palpable uterine contractions and change in cervical effacement or cervical dilatation on clinical examination. Secondary outcome measures included the incidence of preterm birth, neonatal adverse outcomes, and maternal side effects. RESULTS: There was no difference in the frequency of recurrent episodes of threatened preterm labor requiring another course of intravenous treatment between the study (8/62) and control (6/58) group of women (P=0.879). No differences were found between the study and control groups in any of the predefined secondary outcome measures, ie, delivery before 37 weeks (13/62 vs 7/58, respectively; P=0.288), delivery before 34 weeks (3/62 vs 1/58, respectively; P=0.682) and birth weight (3037-/+573 g vs 3223-/+423 g, respectively, P=0.862). There were more reported maternal side effects in the study group than in control group (47/62 vs 23/58, respectively; P(<0.001). CONCLUSIONS: Additional maintenance ritodrine therapy was unnecessary in women with singleton pregnancy who had an episode of threatened preterm labor successfully treated with intravenous tocolytic therapy. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov Identifier: NCT00290173.

Placental site does not change background uterine electromyographic activity in the middle trimester of pregnancy.

OBJECTIVE: This study was performed in order to assess the potential influence of placental implantation site on transabdominal electromyographic (EMG) assessment of the uterine electrical activity in the middle trimester of pregnancy. STUDY DESIGN: In this prospective study 251 unselected, nulliparous asymptomatic women with a singleton pregnancy underwent transabdominal uterine EMG. Uterine electrical activity was recorded using bipolar electrodes placed on the abdominal surface for 20min. Regarding the placental implantation site and presence of action potentials (AP) pregnant women were divided into two groups: the anterior placenta group (APG) and the posterior placenta group (PPG). Outcome measures were differences in the median frequency (MF) and median amplitude (MA) of AP between the two groups. RESULTS: Action potentials were detected in 56 women: 33/56 in the APG versus 23/56 in the PPG. The parameters analyzed (MF, p=0.527, Fisher's exact test, and MA, p=0.255, Fisher's exact test) did not produce any statistical significant differences between the two groups. CONCLUSION: Background uterine EMG activity measured from the abdominal surface in the middle trimester of pregnancy does not depend on the placental implantation site.
