[Frequency of Utilization of Medical and Paramedical Care in Infants with Excessive Crying: Cross- Sectional Analysis and Parent Survey]. / Inanspruchnahme medizinischer und paramedizinischer Versorgung bei Säuglingen mit exzessivem Schreien: Querschnittsanalyse und Eltern-Survey.

BACKGROUND: Infants can present in the first year of life with excessive, recurrent crying without an apparent illness or failure to thrive. The excessive crying results in a wide variety of problems for infants, parents and health care service. OBJECTIVES: This study aimed at evaluating how often parents of children with excessive crying seek help in the medical and paramedical health care system and which therapies are prescribed. MATERIALS AND METHODS: This study uses data collected within KUNO Kids health study. Families who participated completed questionnaires 4 weeks after birth and answered questions which screened for excessive crying. Families whose child was screened positive completed an additional questionnaire on symptoms, parental management and health care utilization. Data were analysed using descriptive statistics. RESULTS: We received 238 questionnaires from children with excessive crying, 105 fulfilled the modified Wessel criteria. Of these 37 children (36%) were seen by a pediatrician because of crying. 57 (55%) received medications by the pediatrician. 51 (49%) of the parents specified that they also used paramedical therapies due to crying or whining, most often osteopathy. 45 (43%) adapted their own nutrition or their child's nutrition. CONCLUSIONS: Our study shows that parents experience problems in dealing excessive crying. Frequent consultations with pediatricians or use of paramedical therapies are common, demanding additional resources. The parents received different diagnoses for excessive crying. Available drugs like Simeticon, homeopathy or manual therapy are recommended and applied despite largely missing evidence.

Colossal topological Hall effect at the transition between isolated and lattice-phase interfacial skyrmions.

The topological Hall effect is used extensively to study chiral spin textures in various materials. However, the factors controlling its magnitude in technologically-relevant thin films remain uncertain. Using variable-temperature magnetotransport and real-space magnetic imaging in a series of Ir/Fe/Co/Pt heterostructures, here we report that the chiral spin fluctuations at the phase boundary between isolated skyrmions and a disordered skyrmion lattice result in a power-law enhancement of the topological Hall resistivity by up to three orders of magnitude. Our work reveals the dominant role of skyrmion stability and configuration in determining the magnitude of the topological Hall effect.

Birth management and fetal outcome in multiple gestation: analysis of 1.444 births.

PURPOSE: Since the late 1990s, controversies came up concerning the mode of delivery for multiples births. The twin birth study indicated no difference in maternal and fetal outcome between planned vaginal delivery and planned caesarean section, but did not analyze the influence of maternal and fetal characteristics or the obstetric management in vaginal birth. The purpose of this study is to analyze these parameters regarding fetal outcome. METHODS: A large-scale retrospective analysis of twin births (n = 1.444) was performed at a university medical center. The analysis included pregnancy, delivery, and maternal and fetal parameters, including pH and base excess (BE) differences between the first- and second-born twin (delta pH, delta BE). RESULTS: Delta pH correlated significantly with the birth interval for various positions of twins in the womb (p < 0.05). The longer the birth interval, the greater the delta pH with a lower pH of the second twin. Delta BE values were significantly correlated with the birth interval for a combination of twins in cephalic and breech presentation. Furthermore, it could be shown that higher differences in birth weight between the first/second twin are associated with higher delta pH, higher delta BE values (all p < 0.05). We found significantly decreasing delta pH values in vaginal deliveries over secondary and, finally, primary caesarean sections (p < 0.001). CONCLUSION: We conclude a vaginal delivery of twin appears safe if experienced staff monitor birth weight discrepancies, birth interval, and blood values consequently. A good outcome also for the second twin delivered spontaneously is nevertheless feasible if experienced staff is available.

Prevalence, clonality, and pathogenicity of Staphylococcus epidermidis isolates in newborn feces.

Coagulase-negative staphylococci (CoNS) are the most prevalent pathogens causing late-onset sepsis in neonates. The question is whether neonates acquire endemic hospital-adapted clones or incidentally occurring CoNS strains after birth during their hospital stay. Therefore, a prospective study was performed on the prevalence of CoNS in the stool of babies (born vaginally or by cesarean section) during their first days of life. Their clonal relatedness and potential to induce invasive disease were characterized. CoNS were analyzed from the stool samples of newborns with a load of CoNS above 103 colony-forming units (CFU)/mL. The identification of CoNS was performed phenotypically and genotypically. For typing, repetitive polymerase chain reaction (PCR), pulsed-field gel electrophoresis, and multilocus sequence typing were used. Resistance profiles, biofilm production, the presence of icaAD and of IS256 were determined as well. From a total of 207 stool samples (56 newborns), CoNS were detected in 41% of the newborns, mostly on day 3 for the first time (62.5%). Staphylococcus epidermidis was isolated in 85.7% of cases, harbored no IS256 element, and mostly expressed no biofilm. The isolates were separated into four main clusters by repetitive sequence-based PCR. 24% of the strains showed no antimicrobial resistance. 20% were resistant against four antibiotics of two different antibiotic classes. The remaining strains were resistant only against one antimicrobial substance class. Thus, it can be concluded that newborns do not acquire hospital-adapted endemic, multidrug-resistant S. epidermidis isolates during their first days of life. Yet, the results support the thesis that, during hospital stay, environmental parameters may convert sensible/noninvasive S. epidermidis strains into multidrug-resistant strains with characteristics of invasiveness.

Extraesophageal symptoms of gastroesophageal reflux disease during pregnancy.

AIM: Typical symptoms of gastroesophageal reflux disease (GERD) are known to be frequent in pregnancy. The aim of this study was to gain a first estimation of the occurrence of extraesophageal symptoms in this context. METHODS: A prospective longitudinal study was performed on 166 pregnant women and in a control group of 285 women. The diagnosis of GERD was based on the Montreal classification using the reflux disease questionnaire (RDQ). Extraesophageal symptoms were recorded with a self-administered questionnaire. Typical GERD symptoms and extraesophageal GERD symptoms were recorded in each trimester of pregnancy. RESULTS: The prevalence of GERD during pregnancy was 16.9% in the first, 25.3% in the second and 51.2% in the third trimester. The prevalence of GERD in the control group was 6.3%. Asthma was reported by 3.5% of controls and by 6% of pregnant women during pregnancy. Chest pain occurred in 6% of the controls and in 1.8%, 2.4% and 2.4% during the trimesters of pregnancy, chronic cough was reported by 1.1% of controls and 1.2% of pregnant women. With the diagnosis of GERD the odds ratios and 95% confidence intervals for asthma, chronic cough and chest pain in the third trimester of pregnancy were as follows: 1.56 (0.58-4.22) for asthma, 0.91 (0.08-10.28) for chronic cough and 2.04 (0.49-8.46) for chest pain. CONCLUSION: GERD is very frequent during pregnancy with progressive incidence during the course of pregnancy. Extraesophageal symptoms of GERD have an unexpected low prevalence during pregnancy.

[Substance abuse and pregnancy from an obstetric point of view]. / Schwangerenbetreuung bei Drogenkonsum.

INTRODUCTION: In Germany we find about 2 000 newborns per year with a mother misusing drugs. It is to be feared that there is a substantial amount of underreported substance abuse in pregnant women. To care for these pregnancies from an obstetric point of view as well as from an addiction treatment point of view is a challenge for all health-care professionals, due to multiple drugs being used and the special psychosocial and health issues these mothers and babies -present. METHOD: A selective search was undertaken in Pubmed, retrieving reviews and original articles from 2001-2013, with consideration of statements, recommendations and guidelines from national and international associations and committees on the topic. This review is intended to assist gynaecologists, obstetricians and paediatricians during the complex peripartum care for the drug abusing pregnant patient. RESULTS: When offering obstetric care for these pregnancies, several issues have to be taken into account: the special psychological situation of the pregnant drug user, with frequent occurrence of psychiatric comorbidities like depression and anxiety disorders, as well as gynaecological complications like premature labour, intrauterine growth restriction and maternal infectious diseases. The pharmacological complexity of the substances abused and the possible side-effects on the foetus have to be explained to the mother. Maintenance medication for foetomaternal risk reduction and maternal stabilisation remains the state-of-the-art treatment. Furthermore, it is important to explain the neonatal abstinence syndrome to the mother as well as the result of breast-feeding in the presence of smoking and/or infectious diseases. DISCUSSION: Professionalism and empathy are needed from gynaecologists in order to achieve risk reduction for mother and child in substance-using pregnancies. However, in spite of close cooperation of all health-care professionals and avoidance of stigma, it will be difficult to offer good obstetric care to the high-risk patients with poly-drug abuse.

Three-dimensional ultrasound of pelvic floor: is there a correlation with delivery mode and persisting pelvic floor disorders 18-24 months after first delivery?

OBJECTIVE: Three-dimensional (3D) transperineal ultrasound has been shown to be a reliable and reproducible method for visualization of morphological changes in the female levator ani muscle. The aim of this study was to evaluate the relationship between persisting pelvic floor disorders 18-24 months after first delivery, biometric measurements of the pelvic floor and mode of delivery. METHODS: In this prospective observational study, we recruited on their second day after delivery 130 primiparous women. All were Caucasian and their pregnancies had been singleton with cephalic presentation. 3D transperineal ultrasound was performed, with standardized settings, on the second day (results published previously) and 18-24 months after delivery. Volumes were obtained at rest and on Valsalva maneuver and biometric measurements of the levator hiatus were determined in the axial plane. Obstetric and constitutional parameters were obtained from our clinical files and, 18-24 months after the delivery, a standardized questionnaire was used to evaluate persisting pelvic floor disorders. Ultrasound measurements at 18-24 months were compared according to clinical symptoms of pelvic floor disorders and mode of delivery, including a subgroup analysis of vaginal (spontaneous vs operative vaginal) and Cesarean (primary i.e. elective vs secondary i.e. after onset of labor) delivery groups. RESULTS: Seventy-seven (59%) women had complete follow-up at 18-24 months. Biometric measurements showed a significantly larger hiatal area in the vaginal delivery group than in the Cesarean section group 2 years after delivery (P < 0.01), whereas subgroup analysis within the vaginal and Cesarean delivery groups did not show significant differences. Although there was no statistical correlation between delivery mode and persisting stress urinary incontinence, women with persisting stress urinary incontinence 2 years after delivery had a larger hiatal area than did women without this clinical symptom (P < 0.01). There were no significant differences in hiatal dimensions in women with bladder urgency or dyspareunia. CONCLUSIONS: 3D transperineal ultrasound, which is easily accessible, can provide useful information on morphological changes of the female pelvic floor. Women with a spontaneous or operative vaginal first delivery had a significantly larger hiatal area and axial distension than did women whose first delivery was by Cesarean section, even 2 years after delivery. Performing 3D ultrasound after the first delivery may help to identify women at high risk for persisting pelvic floor disorders.

[Novel uses of afterbirth tissues in regenerative medicine]. / Neue Verwendungsmöglichkeiten von Nachgeburtsgewebe für die Regenerative Medizin.

INTRODUCTION: Afterbirth tissues, which include the umbilical cord, placenta, amnion, and cord blood, are usually discarded. Recent progress in regenerative medicine suggests that we re-evaluate these tissues and assess their therapeutic potential. METHODS: Firstly the unique properties of afterbirth tissues and their current use in regenerative medicine are summarised. Then we introduce the cooperation of our institutions and our experiences regarding the collection and utilisation of afterbirth tissues. RESULTS: A literature survey suggests that besides the well-known transplantation of hematopoietic stem cells from cord blood, afterbirth tissues were also used as a source of stem cells, progenitor cells, differentiated cells, and blood vessels for tissue engineering purposes. According to our own experience, the two participating OB/GYN departments and the blood donation service were able to organise a sufficient supply of umbilical cords for research purposes. The yield correlated with incentives for the midwives. A total of more than 4,300 cords was collected for experiments designed to create small caliber vessel grafts. The contamination rate was low. Birth mode significantly affected umbilical vein function, whereas ischaemia for up to 40 h did not have any deleterious effects. Umbilical veins were cryopreserved with a moderate loss of function. Fresh umbilical veins were endothelium-denuded and reseeded with endothelial cells harvested from coronary artery disease patients to generate an autologous surface. CONCLUSIONS: Afterbirth tissues have unique properties which make them ideally suited for regenerative medicine. These tissues can be procured and utilised in research facilities even in the absence of an in-house birthing centre.

Robust modeling of appetite regulation.

The interaction between appetite activation and the energy content of the brain and the body is mathematically modeled. General influence functions with saturation are used to describe the interaction. The resulting class of models is investigated with respect to the circadian periodicity of human food intake. We show that very weak and physiologically reasonable assumptions on the constitutive functions are sufficient to validate the indispensable role of the brain as energy consumer in appetite regulation. Subsequently, implications from our systemic investigations of metabolic systems can be drawn although the quantification of the underlying regulatory pathways is uncertain, incomplete, or incompletely understood.

[Structure and reimbursement in obstetrics - are births in level I perinatal centres economically sound?]. / Struktur und Refinanzierung in der Geburtshilfe -Trägt sich die Geburt im Perinatalzentrum Level I?

INTRODUCTION: The standardization of the profit in the public health system causes the question if obstetrical departments of different structures can work cost-coveringly and which services in the DRG-system operate in deficit or profitably. This problem mainly refers to the hospitals of obstetrical maximal care, namely the perinatal centre of level I. MATERIAL AND METHODS: Based on the body cost accounting according to InEK-Matrix the average actual costs of an obstetrical department level IV, a perinatal centre level I and university hospitals were found out for the obstetrical DRGs and compared with the profits calculated by InEK. An analysis of the costs was carried out concerning the cost relevance for different cost areas. RESULTS: Spontaneous delivery was the service that turned out to be cost-covering in all structures. The real costs of caesarean sections, however, as well as those of some vaginal kinds of delivery, mainly pre-mature births and complicated diagnoses turned out to be not cost-covering. However, the perinatal centre was able to compensate the deficit by the high number of vaginal deliveries. The actual personel costs for physicians were higher in the perinatal center than the InEK-calculation for all obstetrical DRGs. The costs of nursery and the costs of the non-medical infrastructure were partly smaller than those of the InEK-calculation. CONCLUSION: A perinatal center level I can operate cost-coveringly on the basis of the DRG system. To achieve this it's not necessary to increase the number of caesarean sections, but what is needed instead is a high number of normal deliveries and an economical non-medical infrastructure and care.

Three-dimensional ultrasound of the pelvic floor 2 days after first delivery: influence of constitutional and obstetric factors.

OBJECTIVES: Morphological changes of the pelvic floor during pregnancy and delivery can be visualized by three-dimensional (3D) perineal ultrasound. The aim of this study was to compare biometric measurements of the levator ani muscle according to maternal constitutional factors, delivery mode and size of the baby immediately after the first delivery. METHODS: In this prospective observational study, 130 primiparae were recruited (all of them Caucasians with singleton pregnancy and cephalic presentation). A 3D perineal ultrasound scan was performed on the second day after delivery with standardized settings. Volumes were obtained at rest and on Valsalva maneuver, and biometric measurements of the levator hiatus were determined in the axial plane. Different obstetric and constitutional parameters were obtained from our clinical files. RESULTS: All biometric measurements of the levator hiatus were significantly greater in the vaginal delivery group than in the Cesarean section group (P < 0.001), whereas subgroup analysis within the vaginal (spontaneous vs. operative vaginal) and Cesarean (primary vs. secondary) delivery groups did not show statistically significant differences. There was no demonstrable influence of maternal constitutional factors (age, body mass index (BMI)) or different obstetric parameters (length of second stage of labor, episiotomy, maternal injuries) on levator hiatus size postpartum, even in subgroups that delivered vaginally. Women with de novo postpartum stress incontinence showed a significantly higher mean levator hiatus transverse diameter and larger hiatal area on Valsalva maneuver (P < 0.05). There was also a positive but very weak correlation between the newborn's head circumference and hiatal dimensions at Valsalva maneuver (P < 0.05). CONCLUSIONS: Pelvic floor imaging by 3D ultrasound is easily accessible even on the first days after delivery and can provide useful information on morphological changes of the levator ani muscle. In our study, women with vaginal or operative vaginal delivery had a significantly larger hiatal area and transverse diameter than women who delivered by Cesarean section. Maternal constitutional factors (BMI, age) and duration of second stage of labor had no influence on the biometric measurements of hiatal area, whereas weight and head circumference of the baby showed a positive correlation with area of the levator hiatus.

[Reliability of fetal pulse oximetry for the detection of fetal acidosis]. / Die Zuverlässigkeit der fetalen Pulsoxymetrie bei der Detektion einer fetalen Azidose.

Fetal pulse oximetry is a continuous method to exclude the lack of oxygen in cases of non-reassuring fetal heart rate. This study aims at the evaluation of the predictive value of this method concerning the development of fetal acidosis. 136 fetuses with non-reassuring heart rate were monitored by fetal pulse oximetry. In all cases fetal blood pH and base excess were determined repeatedly by fetal blood analysis (FBA). The pH value and base excess in the umbilical artery and scalp blood as well as the changes of pH and base excess were correlated to the duration of low, medium and high fetal oxygen saturation (FSpO (2)). Sensitivity, specificity, positive and negative predictive values were calculated for the assumption that "FSpO (2) < or = 30 % for at least 10 or 15 minutes" predicts a pH or base excess in the umbilical artery and in FBA of < 7.1/7.15/7.2 or < or = -4/8/12 mmol/L and a decline of pH (base excess) by more than 0.05 (0.1) pH units (4 mmol/L). A highly significant negative correlation was found between umbilical artery and FBA pH and base excess as well as the change of both and the duration of low oxygen saturation. Additionally the change of FBA pH depends on the duration of medium FSpO (2). A pH below 7.15 in FBA as well as base excess < or = -12 mmol/L were safely detected by a cut-off of "FSpO (2) < or = 30 % for at least 10 minutes" and pH < 7.1 and base excess < or = -12 mmol/l in FBA in 100 % and 75 %, respectively. A decline of pH by more than 0.1 pH units and of base excess by more than 4 mmol/L were excluded by a negative predictive value of 98 %. In conclusion, medium and progressive acidosis can be reliably excluded by fetal pulse oximetry.

[Fetal pulse oximetry during risk deliveries in German clinics--a representative national survey in 81 obstetric departments]. / Uber den Einsatz der fetalen Pulsoxymetrie bei Risikogeburten in deutschen Kliniken - Ergebnisse einer repräsentativen Anwenderumfrage an 81 Geburtskliniken -

BACKGROUND: The development of a new technique to evaluate the normal fetal acid-base balance in risk deliveries with pathological fetal heart rate has been seen with great expectations over the last years. The aim of this representative survey was to ask for the actual status of the fetal pulse oximetry in clinical use in German delivery rooms and to analyze hopes, expectations and system errors. PATIENTS RESPECTIVELY AND METHODS: Collecting data were done by a representative, time limited anonymous questionnaire in all German clinics who used Nellcors fetal pulse oximetry N-400 in measuring fetal arterial saturation in the years 1995 - 1999 during risk deliveries with non-reassuring fetal heart rate. RESULTS: With 66,6 % of the departments participating a number of 54 clinics returned the questionnaires. An average of 4.5 times per month fetal pulse oximetry was used per clinic and in over 90 % of all cases the handling and fixation of the sensor was without problems. There is qualified staff in every clinic and regarding the satisfaction with this system an average note of 2.8 was assigned. Fetal pulse oximetry will be established in some years to replace fetal blood analysis and to reduce operative deliveries. Technical problems in cases of insufficient sensor fixation at the fetal head and with the re-sterilization of fetal sensors must be solved in the future. CONCLUSIONS: Fetal pulse oximetry will be incorporated as the third method of monitoring the fetus during labor.

Oxygen saturation in healthy newborn infants immediately after birth measured by pulse oximetry.

Pre- and postductal arterial oxygen saturation (SpO2) rates were measured in 50 healthy vaginally delivered newborn infants to establish reference values of SpO2 rates immediately after birth. We compared the SpO2 values in the pre- and postductal areas and assessed the influence of oxitocin and analgetics applied during delivery. Fifty neonates were examined by the 2nd minute (min) of life using Nellcor N-3000 pulse oximeters on the right hand and foot. Measurements were carried out until a SpO2 of 95% was achieved. Heart rates were registered simultaneously. Two min after birth the mean preductal SpO2 was 73% (44-95%) and 67% (34-93%) in the postductal region. SpO2 rates of > 95% were reached after 12 min (2-55 min) preductally and after 14 min (3-55 min) postductally. Our results demonstrate that it takes 12-14 min for healthy neonates to reach an oxygen saturation of 95% prerespectively postductal, in some cases even 55 min. All neonates were in good clinical condition and didn't require any supplemental oxygen. Additionally, we were able to show that epidural anaesthesia (PDA) during delivery increases the heart rate of the newborn infant.

Fetal pulse oximetry and other monitoring modalities. Future directions.

Although in the beginning phase of its use, the application of fetal oximetry in high-risk obstetrics is predicted to increase. Even at its early clinical application, patient data have shown that fetal oximetry has the excellent potential to be used with other fetal monitoring modalities to further characterize the metabolic state of the fetus, especially during labor. Similar to other monitoring modalities, the clinicians also need to be aware of its limitations.

Disseminated intravascular coagulation.

OBJECTIVES: To provide an overview of the pathophysiology, manifestations, diagnosis, and treatment of disseminated intravascular coagulation (DIC) as it occurs in cancer. DATA SOURCES: Published articles, research reports, and book chapters. CONCLUSIONS: The syndrome of DIC is a serious hypercoagulation state that in its acute form may be life-threatening. The hemorrhage and intravascular coagulation that occur with DIC may lead to irreversible morbidity and mortality. Prompt recognition and emergency treatment are necessary to help minimize morbidity and mortality. IMPLICATIONS FOR NURSING PRACTICE: Nurses can play an important role in early recognition of DIC to allow for prompt intervention. Nurses caring for patients affected by DIC will be providing complex nursing care, in addition to psychosocial support to patients and families.
