We present a newborn infant with paraplegia and contractures of the lower limbs, consistent with neurologic injury rather than malformation. The mother was involved in a severe motor vehicle accident during the sixth month of pregnancy. We propose that this infant's injuries are a result of that accident. © 1992 Wiley-Liss, Inc. 相似文献

Postpartum weight, body mass index (BMI), triceps skinfold thicknesses (TSF) and upper arm circumferences (AC) were measured bimonthly for 24 months in a large cohort of urban and rural Filipino women. Weight loss, leading to an increasing prevalence of low BMI (<18.5) is the norm in this population where dietary intakes of energy, calcium, and iron fall below WHO recommended intakes. The effects of lactation on postpartum changes in weight and TSF during 6-month intervals were examined by stratifying women into groups defined by lactation duration. In addition, multivariate models were used to examine the effects of lactation on changes in weight or TSF while controlling for other factors such as energy intake, seasonality, morbidity, pregnancy interval, parity, and age. Lactation was associated with significantly increased weight losses from birth to 18 months postpartum. Furthermore, full lactation (breast-feeding with the addition of less than 20 kcal/day to the infant's diet) also significantly increased weight loss in the first 6 months, when the overall duration of lactation in that interval was controlled. Lactation had a small but statistically significant effect on changes in TSF as well. © 1992 Wiley-Liss, Inc. 相似文献

Shaken baby syndrome refers to the constellation of nonaccidental injuries occurring in infants and young children as a consequence of violent shaking. The typical victim of shaken baby syndrome is a male infant younger than six months of age who is alone with the perpetrator at the time of injury. Occurrence of the syndrome is unrelated to race, gender, socioeconomic status, or education. The characteristic injuries observed in shaken baby syndrome include subdural hemorrhages, retinal hemorrhages, and fractures of the ribs or long bones. Although each of these injuries may result from violent shaking of the victim, the most severe brain injuries result from the addition of a forceful impact of the infant's or child's head against a firm surface. The unique anatomic features of the infant's head and skeletal system, which account for the type and pattern of injuries observed in shaken baby syndrome, are emphasized in this article. Anat. Rec.

A total of 260 females were studied in an iodine-deficient regions in different periods of gestation. Among them, 123 females were examined during pregnancy and within 3 months of lactation. Iodine deficiency during pregnancy was shown to form a high risk for diseases in both a child and a mother. There is an increased risk for severe complications of pregnancy and labor, for decreased weight and height, and for the worse status of a fetus and a baby of the first year of life. The use of iodine-containing drugs (100 micrograms iodine a day) is highly effective. 相似文献

The aim of this study was to evaluate the effect of methamphetamine (MA) exposure during pregnancy and lactation on doublecortin (DCX) expression in the hippocampus of rat offspring and also on learning/memory. Thirty-five pregnant Wistar rats were randomly divided into seven groups of 5 rats each: three experimental groups, each receiving 5 mg/kg body weight (BW) intraperitoneal (i.p.) injections of MA during pregnancy or/and lactation; three sham groups, each receiving saline injections; one control group, receiving no injection. After the interventions, two male pups (1 and 22 days old) were randomly selected from each mother, sacrificed and their brains subjected to DCX immunohistochemistry. One additional male pup from each mother was randomly selected and maintained for 60 days for testing in the Morris water maze and passive avoidance tests. MA administration during pregnancy was found to have significantly decreased the number of DCX-positive cells in the CA1, CA3 and DG regions of the hippocampus in the 1-day pups (P ≤ 0.05) and to have significantly decreased the number of DCX-positive cells in only two regions of the hippocampus, the CA1 and DG regions, in 22-day old pups. In comparison, exposure to MA during lactation was only associated with a significant decrease in the number of DCX-positive cells in the DG. Exposure to MA during pregnancy had significant impact on the intensity of DCX expression in the hippocampus of 1- and 22-day pups (P ≤ 0.05). There was no significant difference in memory/learning among the study groups. Our results indicate the administration of MA during pregnancy had a greater effect that during the lactation period on DCX expression in the hippocampus of rat offspring. 相似文献

The aim of this study is to evaluate the clinical feature and pregnancy outcome in patients with ovarian cancer diagnosed during pregnancy. We retrospectively analyzed the medical records of 27 patients diagnosed with ovarian cancer during pregnancy at Cheil General Hospital & Women''s Healthcare Center from January 1996 to December 2006. Mean age of the patients was 29.1 yr (range 23-40), and a mean follow-up period was 57 months (range 7-112 months). Of 27 patients, 15 (55.5%) had borderline malignancies, 7 (25.9%) had epithelial malignancies and 5 (18.6%) had germ cell tumors. A total of 26 patients received a conservative surgery preserving pregnancy. The mean time for surgical intervention during pregnancy was 20 weeks of gestational age. Of the 27 patients, 26 had full term delivery of a healthy baby without any congenital malformation. Only one patient with epithelial ovarian cancer had a relapse at 19 months after the first conservative operation with adjuvant chemotherapy. There were few data for managing patients with ovarian cancer diagnosed during pregnancy. This study results could help establish a guideline for management of ovarian malignancy complicating pregnancy. 相似文献

We report a case of a non-Hodgkin's lymphoma (NHL) patient treated successfully with combination chemotherapy during pregnancy who delivered a full-term baby. A 29 year-old patient with cervical and inguinal lymphadenopathy in the 27th week of gestation was referred to our hospital. The diagnosis of lymph node biopsy was NHL (diffuse, large cell type with B-cell phenotype). Three courses of CHOP regimen (adriamycin, cyclophosphamide, vincristine and prednisolone) were given before delivery. The patient has been in complete remission for three years and her baby has been in normal development. Our case supports previous reports that chemotherapy in the third trimester may be given safely on NHL patients. 相似文献

Objectives: This study evaluated changes in breast size during pregnancy depending on infant sex. Due to larger nutritional needs during lactation, male infants may stimulate greater changes in maternal breast size than female infants. Methods: Data were collected by an online questionnaire survey of 120 women from Poland, who had at least one child. Results: Changes in breast circumference during pregnancy were associated with the infant's gender. Surprisingly, mothers offemale infants had greater breast circumference changes than the mothers of male infants (P = 0.03). Conclusion: The observed difference is surprising in the light of studies reporting that mothers of male infants produced milk that had greater energy content. However, breast size alone does not determine the quality and quantity of produced milk. It is suggested that the larger difference in breast size for mothers of female infants results from a trade‐off between direct energy allocations to the growing fetus and to breast enlargement. Perhaps, as in other primates maintaining sexually attractive attributes during pregnancy, early breast enlargement in women is a primary sexual stimulus. The ultimate function of early breast enlargement may function to ensure greater involvement from partners, which is especially important to mothers expecting daughters, who might be in poorer nutritional condition, as predicted by Trivers‐Willard hypothesis.

Demands on cardiovascular function and fluid turnover increase during lactation and pregnancy in the goat, but the hormonal status is different. This study is aimed at investigating the effects of hypertensive angiotensin II (ANGII) in lactating goats. The results were compared with those of pregnancy and control conditions. ANGII (0.5 pg min-1) was infused intravenously for 60 min (n = 6). The rise in blood pressure in response to ANGII was attenuated during lactation as in pregnancy (P < 0.001 vs control period). ANGII caused reflex bradycardia. Plasma protein concentration decreased by 7.5% during infusions in lactating goats (pregnancy: 9%; control period: 4.5%). Renal Na excretion increased by 260% (lactation), by 400% (pregnancy; n.s. vs. lactation), and by 800% (control period; P < 0.01 vs. lactation). The glomerular filtration rate was unchanged during ANGII infusions in lactating animals, but increased in the other periods. Effective renal plasma flow decreased. ANGII raised aldosterone from < 34.5 pmol 1--1 to 539 ± 80 pmol l-1 (lactation) and to 428 ± 41 pmol l-1 (control; P < 0.05 vs. lactation), and from 72 ± 9 to 651 ± 103 pmol l-1 (pregnancy; P < 0.01 vs. lactation). Plasma progesterone was undetectable during lactation, but varied from 0 to 17 nmol l-1 during control conditions and was 16 ± 1 nmol l-1 during pregnancy. Oestradiol 17β was 181± 22 pmol l-1 in pregnant goats, and undetectable in lactating animals. In conclusion, lactation affects ANGII-induced changes in cardiovascular and fluid regulation, but in this period the effects were not related to progesterone or oestradiol 17 β. 相似文献

This study investigated lateral biases in nipple preferences, maternal cradling, carrying, and retrieval in 41 rhesus macaque (Macaca mulatta) mother–infant dyads living in two captive social groups. Observations were made during the first 6 weeks of infant life using a combination of scan sampling and ad-libitum sampling techniques. Infants exhibited a significant left-nipple preference in the first weeks of life but the bias decreased with infant age. Mothers showed a left-arm bias in carrying their infants but no significant lateral bias in cradling or retrieval. Our results suggest that the left-side cradling bias reported in studies of humans and some other primates reflects a bias in the infant's nipple preference rather than in maternal behavior. The infants' preference for the left nipple is consistent with both Salk's (1960) heartbeat hypothesis and with more recent hypotheses linking this lateral bias with brain asymmetry and hemispheric specialization for mother–infant communication. © 1998 John Wiley & Sons, Inc.

A case of congenital toxoplasmic chorioretinitis was diagnosed (specific-immunoglobulin G [IgG] and -IgM comparative Western blot analysis) in a baby whose mother was immune during pregnancy. Maternal sera showed an increase in specific IgG and emergence of both IgM and IgA during pregnancy. The mother was probably reinfected through contact with kittens. 相似文献

Abstract Role reversal, whereby a child attempts to meet her parent's adult needs for parenting, intimacy, or companionship, has been identified as a risk factor for developmental disturbances. It has been defined from diverse perspectives as a child attachment strategy, a parent – toddler relational disturbance, and a boundary disturbance between parents and child. The recently discovered infant's triangular capacity, namely the sharing of her attention and affects with both parents, allows one to analyse the infant's contribution to early family dynamics. Role reversal was detected in 4 out of 45 father – mother – infant interactions observed in trilogue play from pregnancy to toddlerhood. The developmental trajectories towards role reversal are explored by means of case analyses. Results are compared with cases of problematic triangulation encountered in the same sample. In role reversal, family interactions are rigidly organized around a “two against one” coalition, whereby the normative hierarchy between parents and child is reversed. The child's triangular capacity is overactivated, controlling the tension between her parents by provocation – animation strategies. 相似文献

Maternal immune responses during pregnancy are critical in programming the future health of a newborn. The maternal immune system is required to accommodate fetal immune tolerance as well as to provide a protective defence against infections for the immunocompromised mother and her baby during gestation and lactation. Natural immunity and antibody production by maternal B cells play a significant role in providing such immunoprotection. However, aberrations in the B cell compartment as a consequence of maternal autoimmunity can pose serious risks to both the mother and her baby. Despite their potential implication in shaping pregnancy outcomes, the role of B cells in human pregnancy has been poorly studied. This review focuses on the role of B cells and the implications of B cell depletion therapy in pregnancy. It highlights the evidence of an association between aberrant B cell compartment and obstetric conditions. It also alludes to the potential mechanisms that amplify these B cell aberrances and thereby contribute to exacerbation of some maternal autoimmune conditions and poor neonatal outcomes. Clinical and experimental evidence suggests strongly that maternal autoantibodies contribute directly to the pathologies of obstetric and neonatal conditions that have significant implications for the lifelong health of a newborn. The evidence for clinical benefit and safety of B cell depletion therapies in pregnancy is reviewed, and an argument is mounted for further clinical evaluation of B cell‐targeted therapies in high‐risk pregnancy, with an emphasis on improving neonatal outcomes and prevention of neonatal conditions such as congenital heart block and fetal/neonatal alloimmune thrombocytopenia. 相似文献

In the rat, peripheral glucagon concentrations were studied throughout pregnancy and lactation. Basal glucose concentrations were decreased during late pregnancy and during lactation, but basal glucagon concentrations were not affected. Infusion of glucose (7.4 mg/min) caused an elevation of the glucose concentrations, which became lower in the course of lactation, and a suppression of the glucagon concentrations which was the same throughout pregnancy and lactation. Ingestion of 336 mg of glucose or 1 g of rat chow throughout pregnancy and lactation induced a transient increase of the glucose concentrations and a biphasic glucagon response: following a short-lasting elevation, the glucagon concentrations became suppressed. The glucagon responses to these tests did not change during pregnancy and lactation. It is concluded that the regulation of the peripheral glucagon concentration is not affected by pregnancy or lactation, and that the response of the glucagon concentration to a metabolic challenge varies with the kind of test (oral or intravenous) used. 相似文献

Both scent marking frequency and nest building activity increase during pregnancy and early lactation, and then gradually fall off to prepregnancy levels by the end of lactation. Females ovariectomized two days after parturition fail to show the normal increase in marking in early lactation. In addition, ovariectomy of nonpregnant females causes a significant decline in marking frequency, thus implicating ovarian secretions in the control of female scent marking. The presence of the mother's sebum on a strange pup enhances the pup's probability of being retrieved to the nest, suggesting that scent marking aids the mother in identifying her pups. The role of the hormones of pregnancy in regulating many aspects of maternal behavior is emphasized. 相似文献

The emotional bond that a mother feels towards her baby is critical to social, emotional and cognitive development. Maternal health and wellbeing through pregnancy and antenatal bonding also play a key role in determining bonding postnatally, but the extent to which these relationships may be disrupted by poor mental health or substance use is unclear. This study aimed to examine the extent to which mother-fetal bonding, substance use and mental health through pregnancy predicted postnatal mother-infant bonding at 8 weeks. Participants were 372 women recruited from three metropolitan hospitals in Australia. Data was collected during trimesters one, two and three of pregnancy and 8 weeks postnatal using the Maternal Antenatal Attachment Scale (MAAS), Maternal Postnatal Attachment Scale (MPAS), the Edinburgh Antenatal and Postnatal Depression Scale (EPDS), the Depression and Anxiety Scales (DASS-21), frequency and quantity of substance use (caffeine, alcohol and tobacco) as well as a range of demographic and postnatal information. Higher antenatal bonding predicted higher postnatal bonding at all pregnancy time-points in a fully adjusted regression model. Maternal depressive symptoms in trimesters two and three and stress in trimester two were inversely related to poorer mother-infant bonding 8 weeks postnatally. This study extends previous work on the mother’s felt bond to her developing child by drawing on a large sample of women and documenting the pattern of this bond at three time points in pregnancy and at 8 weeks postnatally. Utilising multiple antenatal waves allowed precision in isolating the relationships in pregnancy and at key intervention points. Investigating methods to enhance bonding and intervene in pregnancy is needed. It is also important to assess maternal mental health through pregnancy. 相似文献

A 29-year-old lady was diagnosed with lecithin:cholesterol acyltransferase (LCAT) deficiency having presented with bilateral corneal clouding, severely reduced high density lipoproteins cholesterol, and proteinuria. She is a compound heterozygote with two LCAT gene mutations, one of which is novel, c.321C>A in exon 3. Surprisingly, the level of proteinuria significantly improved during pregnancy, despite stopping the angiotensin-converting enzyme inhibitor. However, LCAT concentration and activity remained identical during pregnancy and postpartum. Her pregnancy was complicated by rising triglyceride levels from the second trimester requiring treatment with omega-3 fatty acid and fenofibrate. In the last trimester, a further complication arose when she became hypertensive and proteinuria worsened. She was diagnosed with pre-eclampsia and had an emergency cesarean section at 39 weeks delivering a healthy baby. This case adds to the knowledge of the pathophysiology of LCAT deficiency during pregnancy and will be useful in future patient management. 相似文献

Water and salt balance was studied in the same goats during pregnancy, lactation and anestrus. All goats increased their water intake during the course of pregnancy, but individual differences were large. In general, twin pregnant (TP) goats drank more water than single pregnant (SP) animals (3.4±0.4; N=11 as compared to 2.5±0.3 litres/day; N=5) during the last weeks of pregnancy. During lactation the high water intake of TP goats persisted and the SP animals increased their intake to the same level as the TP goats. The water intake was reduced to about 2 1/day in both categories of animals during anestrus. Urine volume largely followed the changes in water intake in the individual animal. A continuous decrease in urine osmolality during the course of pregnancy occurred, but during lactation urine osmolality increased towards anestrus levels. TP goats generally retained more sodium than SP animals during pregnancy and during anestrus, whereas the figures were similar during lactation. Plasma Na, K and osmolality remained unchanged during pregnancy, lactation and anestrus, but a large fall in total plasma proteins and a moderate fall in hematocrit were observed during the course of pregnancy. Glomerular filtration rate of TP goats was elevated by about 35% during the 4th month of pregnancy, but did not differ from anestrus levels during the 3rd and 5th month or during lactation. Effective renal plasma flow was highest during the 3rd pregnancy month and then fell to reach lactation and anestrus levels during the 4th month of pregnancy. A few hours before parturition the animals became markedly dehydrated as shown by sudden increases in plasma Na, K, osmolality, total proteins and hematocrit. This water deficit was replenished within 26 h post-partum. 相似文献

This study evaluated whether a new predictive rule is more accurate for estimating the length of pregnancy in African Americans than Nägele''s rule, the accepted standard. After identifying women in early pregnancy, telephone interviews were conducted to obtain information about 16 previously established determinants of gestational length. Based on these data, a linear multivariate regression model was used to predict an estimated delivery date (EDD) for each mother. In addition, the EDD was determined using Nägele''s rule. Later, the actual delivery date was compared with the EDD predicted by the new rule and with the EDD predicted by Nägele''s rule. Each pregnancy was assigned to its better prediction group, either the new rule''s group or the Nägele''s rule group. Fifty-seven pregnancies were identified prospectively and monitored. The new rule predicted the actual delivery date more accurately in 66% (37/56) of pregnancies, Nägele''s rule was a better predictor in 34% (19/56) of pregnancies, and both rules were equally accurate in predicting the delivery date for one pregnancy. The new rule was more precise than Nägele''s rule (P = .022) when the binomial distribution was used. When using the linear regression model rule, a more accurate EDD can be determined for African-American women. Moreover, it is possible to predict the risk of preterm delivery (those occurring > 3 weeks earlier than the EDD). 相似文献
