Aseptic avascular necrosis of the femoral condyles in renal transplant patients: clinical and radiological aspects on 69 knees

Three cases of primary hyperparathyroidism in pregnancy are described. Patient 1 developed left thigh pain and lower abdominal pain at 34 weeks' gestation. Patient 2 had right flank pain and lower abdominal pain at 32 weeks' gestation. Both patients accepted medical therapy initially, which resulted in poor control of hypercalcemia. Patient 1 delayed her parathyroidectomy until the postpartum period; she had maternal hypercalcemia and neonatal hypocalcemia. Patient 2 accepted parathyroidectomy at 32 weeks' gestation with an uneventful outcome for both mother and baby. Patient 3 was asymptomatic; her hyperparathyroidism was diagnosed postpartum after neonatal hypocalcemia and agreed to parathyroidectomy. All 3 patients had a parathyroid adenoma.     

Follow-up treatment after surgery of internal derangement of temporomandibular joint--a survey of 20 patients

The simultaneous occurrence of primary hyperparathyroidism (PHPT) and pancreatitis during pregnancy is very rare. We present a case of concurrent PHPT and pancreatitis in pregnancy and review 13 cases reported in the English and Japanese literature. Two maternal and three fetal deaths occurred. Mortality seemed to be related to delayed resection of the parathyroid tumor. Morphologically, severe pancreatitis was only seen in three cases, whereas even edematous or focal pancreatitis caused the same symptoms as clinically severe pancreatitis. Acute pancreatitis should be kept in mind in the differential diagnosis of unexplained nausea and abdominal pain during pregnancy, and hyper-or normocalcemia in the severe form of pancreatitis should be a clue to concurrent PHPT.     

Assessing the relationship between maternal opiate use and neonatal mortality

We undertook a number of meta-analyses to estimate more precisely the relationship between neonatal mortality and use of opiates in three groups of women. First, women who continued to use illicit heroin throughout pregnancy; secondly, women stabilized on methadone at the time of conception or shortly after and thirdly, women who use heroin well into pregnancy with late entry into methadone treatment, or who continued to use illicit heroin during pregnancy while receiving methadone. FINDINGS: The pooled estimates of the relative risks of neonatal mortality for separate heroin and methadone use were both near unity: 1.47 (95% CI 0.88-2.33) and 1.75 (95% CI 0.60-4.59), respectively. The result for heroin may be due to the inclusion in the meta-analysis of a particularly large study, which, unlike the two other smaller studies included found a relative risk near unity. When this study was excluded from the meta-analysis the pooled estimate of the relative risk of neonatal mortality for heroin use was 3.27 (95% CI 0.95-9.60). In contrast to the results for use of methadone only, the pooled relative risk associated with heroin and methadone use was 6.37 (95% CI 2.57-14.68). CONCLUSIONS: The increased relative risk for neonatal mortality associated with women using heroin and methadone during pregnancy, compared to those stabilized on methadone, is probably due to the chaotic and high-risk life-style associated with illicit heroin use and not solely to the use of heroin and methadone per se. It is recommended tht women who use heroin well into pregnancy with late entry into methadone treatment, or who continue to use illicit heroin during pregnancy while receiving methadone, receive special attention over and above that provided to women stabilized on methadone.     

Pregnancy after surgical therapy of obesity. Bibliographic review and our experience with biliopancreatic diversion

BACKGROUND: An increasing number of women in childbearing age are submitted to surgical treatment of obesity; for this reason pregnancy represents a frequent event in operated patients. METHODS: In this study pregnancy in patients with morbid obesity submitted to jejunoileal bypass (JIB) and gastric bypass (GB) are reviewed from the literature and the analysis of our experience with biliopancreatic diversion (BPD) is reported. RESULTS: In 113 pregnancies after JIB reviewed from the literature, the results seem to be debated either about the course of pregnancy or about maternal and neonatal status. The data of literature concerning the pregnancies following GB are less debated but rather slight. One hundred and fifty-two pregnancies after BPD have a complete documentation concerning maternal conditions, modality of outcome and neonatal situation. CONCLUSIONS: Pregnancy occurred in the obese women represents an increased maternal-fetal risk. The excess weight loss, the weight maintenance and the reduced weight changes during pregnancy are an advantage in the operate women who, in any case, need accurate controls of the nutritional status during the whole gestational period. Keeping these cautions pregnancy following surgical treatment of obesity represents an event not only possible but even with less problems than in pregnancy in obese women.     

Effects of social, familial, and maternal state variables on neonatal and infant health.

The medical protocols of a Danish birth cohort of 5,036 infants were summarized into 5 infant outcome measures: birth weight, neonatal physical health, neonatal neurological status, 1-yr physical health, and 1-yr motor development. All Ss received uniform medical care during pregnancy. 17 indices representing both medical and environmental variables were used as predictors in hierarchical regression analyses. Consistent negative environmental influences on neonatal outcomes were not found, presumably due to the uniform medical care during pregnancy that each mother received. A stronger environmental influence was observable at 1 yr of age. Institutional daycare, mother's employment, family size, whether the child was planned, and SES all contributed significantly to the regression equation for 1-yr physical health. This effect was anticipated, since no uniform medical treatment was provided the cohort subsequent to birth. (46 ref) (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Pathogenic factors in idiopathic mental retardation

Pathogenic factors in a mentally retarded population were evaluated by comparing their frequency among three groups of patients: a control group with predominantly genetic retardation and consanguineous parents; a group with severe idiopathic retardation and unrelated parents; and a group with mild idiopathic retardation and unrelated parents. Seven factors were found to be significantly more common among the patients with idiopathic retardation than in the genetic control group: a history of maternal reproductive inefficiency; bleeding during pregnancy; toxemia during pregnancy; signs of perinatal stress; neonatal anoxia; neonatal jaundice; and seizures during the first year of life. A history of repeated maternal abortions was particularly associated with mild retardation, and infantile seizures were particularly associated with severe retardation. The latter association remained significant even after exclusion of all infantile spasms, neonatal seizures and symptomatic seizures. Since the control group in this study was composed mainly of genetically retarded patients, the associations observed seem likely to be related to the causes of retardation rather than simply being the effects of a damaged fetus.     

Glycosylated hemoglobin and fetal growth in normal, gestational and insulin dependent diabetes mellitus pregnancies

Aims of the study were: evaluation of HbA1c levels in the peripheral blood of pregnant women with insulin dependent diabetes, gestational diabetes, glucose intolerance, and healthy pregnant controls; implications of HbA1c concentration on detection and the control of women with impaired carbohydrate metabolism in pregnancy; comparison of HbA1c levels with appearance of miscarriages, and premature deliveries; comparison of weight gain during pregnancy to HbA1c levels; comparison of difference from ideal body weight with HbA1c in diabetic pregnant women; comparison of neonatal birth weight and HbA1c levels. 290 pregnant women were enrolled to the study. The highest value of HbA1c was in the group IDDM pregnant women (7.7% +/- 1.8%), and the lowest value of HbA1c was in the control group (4.1% +/- 0.5%). Statistically significant coefficients were found between HbA1c and weight gain during pregnancy, between weight deviation from ideal body weight and HbA1c (r = 0.54 and r = 0.48 respectively); and between newborns weight and HbA1c (r = 0.51). Well regulated glycemia and intensive pregnancy follow-up of diabetic women reduces stillbirths, neonatal complications and neonatal macrosomia incidence.     

Supporting parents during and after a pregnancy subsequent to a perinatal loss

The experience of perinatal loss can be devastating for couples who want children. The decision and desire to attempt another pregnancy may be too much for parents to bear, yet the majority of women who experience perinatal loss do become pregnant again soon after the loss. A pregnancy after a perinatal loss can be mentally, emotionally, and physically taxing. The anxiety experienced by mothers during a subsequent pregnancy has been documented consistently by investigators, but less is known about the effects of perinatal loss on parenting subsequent children. Perinatal and neonatal nurses play a critical role in supporting parents during and after a subsequent pregnancy and need an understanding of the research to direct their practice.     

An audit of cholesterol measurement in patients with ischaemic heart disease in a district hospital

OBJECTIVES: To determine the prevalence of bacterial vaginosis (BV) in pregnant women and to assess the association between BV and adverse pregnancy outcome. METHODS: Bacterial vaginosis was screened in 380 healthy pregnant women during different gestational weeks by clinical features and Grams stained vaginal smears. The pregnancy outcome of these gravidae was followed up. RESULTS: The prevalence of BV in pregnant women was 6.8% (26/380). The incidence of puerperal infection, neonatal infection, and jaundice of newborn were higher in women with BV than those without BV (14.3%, 9.5%, and 23.8% v.s. 2.2%, 1.3%, and 5.4%, respectively P < 0.05, P < 0.05, P < 0.005). CONCLUSION: Pregnant women with BV are associated with maternal infection, neonatal infection, and jaundice of newborn. It is necessary to treat BV during pregnancy.     

Pregnancy and iron deficiency: unresolved issues

Iron deficiency and iron deficiency anemia are prevalent among pregnant women. The extent to which iron deficiency affects maternal and neonatal health is uncertain. Existing data suggest that maternal iron deficiency anemia may be associated with adverse outcomes, including preterm delivery and higher maternal mortality. Further research is needed on the maternal and neonatal benefits of iron supplementation during pregnancy.     

Pregnancy-associated thrombocytopenia revisited: assessment and follow-up of 50 cases

Thrombocytopenia detected during pregnancy addresses the issue of its mechanism and of the possible occurrence of neonatal thrombocytopenia. To further investigate these issues, 50 women referred to us because of thrombocytopenia detected during pregnancy (platelet count, <150 x 10(9)/L), were extensively studied, as well as their offspring. Among these thrombocytopenic women, we used the threshold of 70 x 10(9)/L to differentiate between mild and severe thrombocytopenia. Whatever the severity of thrombocytopenia, we found biological features of an autoimmune disorder in 48% of the women, and chronic thrombocytopenia in 55%. A familial thrombocytopenia was evidenced in 1 case. These 50 women gave birth to 63 neonates, among whom 24 were thrombocytopenic, either at birth or during the first week of life. Neonatal thrombocytopenia could only be predicted in multiparous women, on the basis of previous neonatal thrombocytopenia in older siblings, and/or when maternal platelet life span study, performed before pregnancy, had evidenced an autoimmune thrombocytopenia (AITP)-like profile. These results suggest that, in case of pregnancy-associated thrombocytopenia, familial and immunological studies, combined with postdelivery iterative platelet counts, should be performed to properly characterize the thrombocytopenia. Moreover, the platelet count of the neonate should be carefully assessed at birth and during the following days, a platelet life span study should be performed after delivery in the mother, because these two parameters are likely to bring valuable information regarding the forthcoming pregnancies and the risk of neonatal thrombocytopenia.     

Neonatal death after induced abortion

An obstetrical practice based at a university hospital in Jerusalem has studied the offspring of 9,894 women who were pregnant at least once during the years 1966 through 1968, and discovered that the neonatal mortality rate was 2 to 3 times higher in infants born to women who reported a previous induced abortion. Among the women studied, 7.2% reported at least 1 previous abortion; immigrants from South Africa tended to have the highest rate of abortion, whereas the lowest rate was observed in the Arab population. An inverse relationship was detected between a history of induced abortion and the following: the degree of religious observance; maternal age at the time of marriage; and maternal age at the time of past deliveries. A positive correlation was observed between a history of induced abortion and the present age of the mother; smoking; Caesarian section; bleeding during pregnancy; vomiting during pregnancy; and the use of medications during the 1st trimester of the present pregnancy. The women in this study delivered a total of 11,057 infants between 1966 and 1968; infants born to mothers who reported a previous induced abortion experienced a higher neonatal mortality rate and were more likely to be low birth-weight infants, when compared to the group of infants whose mothers did not report a previous induced abortion.     

Maternal immunization to Gov system alloantigens on human platelets

BACKGROUND: Immunization to platelet alloantigens can occur during pregnancy or after the transfusion of blood components. Platelet alloantibodies can cause neonatal alloimmune thrombocytopenia and posttransfusion purpura. Transfusion-induced alloimmunization to a novel platelet alloantigen system, Gov, expressed on the 175-kDa glycosyl phosphatidylinositol-anchored platelet glycoprotein, CD109, was previously described. This report describes three unrelated patients who were alloimmunized to Gov(a) or Gov(b) during pregnancy. STUDY DESIGN AND METHODS: Platelets were typed by using radioimmunoprecipitation for HPA-1a, -3a, -5a, -5b, Gov(a), and Gov(b) and by polymerase chain reaction-restriction fragment length polymorphism for HPA-1a, -1b, -3a, and -3b. Maternal sera were screened for platelet antibodies by using radioimmunoprecipitation and the antigen capture assay. RESULTS: Patients 1 and 2 were investigated after the diagnosis of neonatal alloimmune thrombocytopenia in their children, and alloantibodies specific for Gov(b) and Gov(a), respectively, were detected in maternal serum. Serum from patient 3, who had mild idiopathic thrombocytopenia purpura with no detectable autoantibody, was found to contain alloantibodies to Gov(b) and to HPA-5b, presumably as a result of immunization during pregnancy. Platelet typings confirmed that the patients were at risk for alloimmunization to the respective antigen. CONCLUSION: This report of three cases of maternal alloimmunization to antigens in the Gov system indicates that immunization can occur via placental transfer of antigen and that Gov system alloantibodies may be associated with neonatal alloimmune thrombocytopenia.     

Glucose and galactose transport in Bifidobacterium bifidum DSM 20082

The onset of psychosis during pregnancy presents several difficult management decisions and a careful risk-benefit analysis is required. Withholding antipsychotic treatment may produce more risks than benefits. Studies on neuroleptic teratogenicity are contradictory. Most of the commonly used neuroleptics exhibit a pregnancy risk of category C. Neuroleptic use during pregnancy may be associated with adverse effects in the pre- and postnatal period. These concerns include compromising uterine blood flow, post-partum neonatal sedation, and extrapyramidal signs expressed in the neonate. Each neuroleptic exhibits a unique pharmacokinetic profile. The antipsychotic properties and side effects considered most significant include sedation, half-life, hypotension, and apparent hydrophilicity. In this case study a decision to select molindone was based on these parameters.     

Early prognostic ultrasonographic indices in pregnancy with fetal cystic hygroma

OBJECTIVE: Aim of this study was the correlation of same early ultrasonographic signs with fetal karyotype, prognosis of pregnancy and neonatal outcome. EXPERIMENTAL DESIGN: Volume of cystic hygroma and presence of septations are correlated with fetal karyotype and an ultrasonographic follow-up was carried out during pregnancy. Details concerning neonatal outcome were recorded at delivery. PATIENTS: Diagnosis was performed in 13 patients between 8.3 to 16.5 weeks' gestation referred to our center for prenatal diagnosis or for obstetric reasons. METHOD: Ultrasonographic examinations were performed using 5.0 and 6.0 MHz endovaginal convex probes. SURVEYS: Hygroma was diagnosed as a cystic dilatation in the nuchal region larger than 3 mm in diameter in the anterolateral aspects. The volume was calculated considering the lesion as spherical and using the standard formula for an ellipsoid volume; the presence of septations was considered. RESULTS: A volume greater than 70 cc3 and the presence of septations demonstrated a strictly correlation with fetal karyotype, evolution of the features, pregnancy and neonatal outcome. CONCLUSIONS: Prognosis varies depending on fetal karyotype, volume, presence of septations and other associated malformations. The volume of the hygroma and the presence of septa are associated with higher incidence of chromosomal diseases and a poorer fetal prognosis.     

Maternal-foetal interaction, antibody formation, and metabolic response in mice immunized with pneumococcal polysacharides

The maternal transfer of pneumococcal polysaccharides to foetus, as well as the antibody formation and metabolic response were studied in mice exposed to pneumococcal polysaccharides during pregnancy. Type 19 and type 57 pneumococcal polysaccharides display cross-placental transfer to foetus. These polysaccharides also transfer through mother's milk to neonates. Maternal immunization of type 19 polysaccharide during pregnancy induced higher antibody formation in the offspring than the group from non-immunized mothers. Young mice, which received a second dose of polysaccharide at 2 weeks of age, showed a higher antibody response than those which did not receive polysacharide. Treatment of mothers with anti-lymphocyte serum, following by administration of polysaccharide, significantly increased the neonatal immune response to the polysaccharide. Treatment of the mother with a high dose of type 19 or type 57 polysaccharide did not cause significant changes in neonatal growth and organ weights. The offspring from mothers treated with high doses of these polysaccharides did not exhibit abnormalities in chemical contents of their tissues.     

Prenatal tobacco exposure: Developmental outcomes in the neonatal period.

Smoking during pregnancy is a persistent public health problem that has been linked to later adverse outcomes. The neonatal period—the first month of life—carries substantial developmental change in regulatory skills and is the period when tobacco metabolites are cleared physiologically. Studies to date mostly have used cross-sectional designs that limit characterizing potential impacts of prenatal tobacco exposure on the development of key self-regulatory processes and cannot disentangle short-term withdrawal effects from residual exposure-related impacts. In this study, pregnant participants (N = 304) were recruited prospectively during pregnancy, and smoking was measured at multiple time points, with both self-report and biochemical measures. Neonatal attention, irritable reactivity, and stress dysregulation were examined longitudinally at three time points during the first month of life, and physical growth indices were measured at birth. Tobacco-exposed infants showed significantly poorer attention skills after birth, and the magnitude of the difference between exposed and nonexposed groups attenuated across the neonatal period. In contrast, exposure-related differences in irritable reactivity largely were not evident across the 1st month of life, differing marginally at 4 weeks of age only. Third-trimester smoking was associated with pervasive, deleterious, dose–response impacts on physical growth measured at birth, whereas nearly all smoking indicators throughout pregnancy predicted level and growth rates of early attention. The observed neonatal pattern is consistent with the neurobiology of tobacco on the developing nervous system and fits with developmental vulnerabilities observed later in life.

Successive relationships between maternal attitudes during pregnancy, analgesic medication during labor and delivery, and newborn behavior.

Asked 85 primiparous mothers in their last trimester of pregnancy to respond to a questionnaire assessing fears regarding pregnancy as well as generalized tension and depression. At delivery, information was obtained regarding obstetric analgesic medication and duration of labor. Two days following delivery, neonatal behavior was described in terms of sleeping and waking behavior. Sequential relationships between each of the 3 phases were examined. Three questionnaire scales were related to 1 of 4 drug variables. Three of the 4 drug variables were related to duration of 1st-stage labor. Three drug variables were correlated with neonatal behavior. Duration of labor was unrelated to neonatal behavior. Multiple regression analyses using pregnancy, drug, and labor variables as predictors did not yield impressive relationships to neonatal behavior.

Antibiotic prophylaxis for gastrointestinal endoscopy

An infant with benign familial neonatal convulsions had abnormal movements during the last 2 months of pregnancy suggestive of intrauterine seizures. His postnatal seizures, one of which was captured by electroencephalography, had both partial and generalized features. Most seizures appeared to be provoked by feeding.     

Maternal attitude toward pregnancy and the risk of neonatal death

OBJECTIVES: Reduced options for fertility control over the past decade have increased the rates of unwanted pregnancy. We evaluated whether a woman's negative attitude toward her pregnancy increased the risk of perinatal mortality, in a large, prospective cohort study. METHODS: The association between attitude toward the pregnancy and perinatal mortality was evaluated in a longitudinal cohort study of 8823 married, pregnant patients enrolled from 1959 to 1966 in the Child Health and Development Studies. RESULTS: Women who reported during the first trimester of prenatal care that the pregnancy was unwanted were more than two times more likely to deliver infants who died within the first 28 days of life than were women reporting accepted pregnancies. A positive attitude toward pregnancy was not associated with fetal death or post-neonatal death. CONCLUSIONS: These data, collected when induced abortions were illegal, may have important implications for the 1990s. If maternal attitude toward the pregnancy is associated with neonatal mortality and abortion laws change such that access is restricted, infant mortality may increase because a greater proportion of births will be unwanted.
