Fetal outcome and childhood mortality in offspring of mothers with sickle cell trait and disease.

The sickle cell hemoglobinopathy is a major public health problem which causes high morbidity and mortality in India. Although the hematological and clinical profile of the patients is extensively studies. The reproductive outcome of mothers afflicted with sickle cell trait and disease is still unknown in India. In a retrospective study, we have examined the reproductive profile of 190 mothers afflicted with sickle cell, attending Medical Out-Patient Department at V.S.S. Medical College Hospital, Burla in Western Orissa, India during the year 1991-1992. Seventy-three mothers who were found normal after medical examination and were free from hemoglobinopathic disorders, anemia, jaundice, iron deficiency, etc. constituted the control group and 66 mothers with sickle cell trait and 51 with sickle cell disease formed the study group. The reproductive history was recorded for number of conceptions, fate of offspring, live birth, surviving children and childhood mortality. Hematological investigations and hemoglobin electrophoresis were done as per the standard procedure. There was no difference in mean number of livebirths per mother between controls and sickle cell trait mothers. But between the controls and sickle cell homozygotes (p < 0.01), and sickle cell trait and disease (p < 0.01) mothers, this mean number was significant. For abortions/miscarriages, the difference between controls and sickle cell homozygotes (p < 0.001), and sickle cell trait and disease (p < 0.01) mothers was highly significant. The number of stillbirths per mother in homozygous sickle cell mothers was higher (p < 0.01) as compared to controls. There were significantly higher childhood deaths in sickle cell trait (p < 0.05) and disease (p < 0.05) mothers than in the controls. It seems that the sickle cell heterozygote and hemoglobin E heterozygote mothers are genetically better fit than the sickle cell homozygotes. Further, the sickle cell disease is clinically severer than the hemoglobin E disease in India probably due to molecular diversity.

The influence of parity on multinodular goiter prevalence in areas with moderate iodine deficiency.

Despite the observation that parity may increase the risk of thyroid carcinoma, very few studies have investigated the possible repercussion of parity on thyroid benign pathology. Recently, parity has been identified as one of the factors contributing to a larger thyroid size in healthy females. The aim of this work was to investigate a possible role for parity on the prevalence of multinodular goiter in iodine deficient areas. For this purpose, the reproductive histories of 2 cohorts of women, normal (Group I, 235 cases) and non-toxic multinodular goiter (NTMNG) affected (Group II, 274 cases) were compared. All subjects were euthyroid and had no previous history of thyroid function abnormalities. The number of full-term previous pregnancies (2.55+/-0.11 vs 1.77+/-0.10) and age (47.7+/-0.76 vs 42.3+/-0.83 yr) were found significantly higher (p<0.001) in multinodular goiter (MNG) patients than controls. Parity and age were found to be directly correlated (p<0.001), nevertheless the partial correlation coefficients demonstrated an independent and statistically significant difference for both variables between normal and NTMNG. Therefore, the independent effects of parity and age were further investigated. The effect of age on NTMNG prevalence seems to be weaker, in fact significant differences (p<0.001) for age between patients and controls were detected only when the effect of parity was absent (nulliparous), while with increasing gestations the effect of age disappeared. Our results indicate that age plays a minor role compared to parity which can therefore be considered as a stronger risk factor. In conclusion, the present study shows that, at least in iodine deficient regions, non-toxic multinodular goiter women show a statistically significant higher parity rate than healthy controls. Age may play a certain role but only when additional stronger risk factors are absent.

Menstrual cycle and ovary alterations in women with epilepsy on antiepileptic therapy.

Impaired reproductive function is thought to frequently affect women with epilepsy, mainly when seizures originate in the temporal lobe. In this study, we evaluated menstrual cycle features and assessed ovulation by determining luteal progesterone (Pg) levels in 101 consecutive women with epilepsy (36 with idiopathic generalized epilepsy -IGE; 65 with partial epilepsy -PE), aged between 16 and 50 years, treated with various antiepileptic drugs (AED). PE originated in the temporal lobe (TLE) in 40 subjects, in the frontal lobe in 13, in the parietal lobe in 2, while the origin of focal seizures remained undetermined in 10 patients. In all patients, menstrual and reproductive history, body mass index, hair distribution and hormonal pattern were assessed. Suprapubic ovary ultrasound (US) examination was carried out in 83 patients (28 with IGE, 55 with PE). Three patients with IGE and one with PE were amenorrheic. Oligomenorrhea occurred in 16 patients, polymenorrhea in 2. Changes in menstrual cyclicity were independent from epilepsy type (19.4% in IGE; 23.1% in PE) and from origin of focal discharges (22.5% of patients with TLE; 20.0% with origin in other brain areas). Luteal Pg levels remained below 2 ng/ml in 30 patients independently of epilepsy type. Corpus luteum dysfunction was combined with hyperandrogenism in 15 of these patients. In the other cases different alterations of hypothalamus-pituitary-ovary axis were observed. Valproic acid blunted luteal Pg surge more frequently than other AED. Polycystic ovaries (PCO) were observed in 14 (16.9%) patients (21.0% with IGE: 14.5% with PE). These prevalences are not higher than those reported in the general population. Among PE patients, PCO was found in 1 case with undetermined focal origin and in 7 TLE cases, who also had ovary volume significantly larger than patients with seizures originating from the frontal or parietal lobe. Epileptic women exhibited an increased occurrence of multifollicular ovaries (MFO) found in 12 cases (14.4% vs 5% in the general population). However, no defined hormonal or clinical pictures were associated with this US alteration in most patients. These findings reappraise the impact of ovary alterations in women mainly affected by mild to moderate epilepsy, on differing AED regimens, with the exception of more frequent ovulatory dysfunction and PCO occurrence in patients taking VPA.

The effect of mode of delivery, parity, and birth weight on risk of urinary incontinence.

To examine the relationship between symptoms of urinary incontinence (UI) and mode of delivery, parity, and birth weight, data were obtained from a population-based random sample of 3,205 black, Hispanic, and white women age 30-79 in the Boston Area Community Health Survey. Measures include UI symptoms [>or=3 (moderate/severe) Sandvik's severity index]; reproductive history [live birth(s), no live births, never pregnant]; mode of delivery for live births (>or=1 vaginal birth, cesarean delivery only); parity (1, 2, >or=3); and maximum birth weight of live births (<4,000 g, >or=4,000 g). Using logistic regression, women having >or=1 vaginal delivery had twice the odds of UI compared to women with no pregnancies (P = 0.002) or only cesarean deliveries (P = 0.032). There was no difference in odds of UI between cesarean delivery only and never pregnant, by parity or birth weight. Vaginal delivery contributes to risk of UI for black, Hispanic, and white women.

Lifestyle factors affecting heel ultrasound in Greek females across different life stages.

The use of quantitative ultrasound (QUS) of the bone is rapidly gaining in popularity, and QUS is widely used worldwide for the assessment of skeletal status. Although much has been learned about the influence of various factors on ultrasonic parameters in various populations, similar information at the local level is not available. This study was carried out to examine the effects of anthropometric, dietary, physical activity, reproductive, and other lifestyle factors on QUS parameters in healthy Greek women, including children (n=217), adults (n=235), and elderly (n=369) subjects. Calcaneal QUS measurements were performed with the SAHARA device, which measures broadband ultrasound attenuation (BUA) and speed of sound (SOS) through the os calcis; a composite parameter, the quantitative ultrasound index (QUI), and an estimate of heel bone mineral density (eBMD) were also derived. All QUS indices were higher in adult women than in girls or elderly women (P<0.05). The latter had a similar BUA to girls, but lower SOS, QUI, and eBMD (P<0.05). Most QUS parameters correlated positively with height, weight, body mass index (BMI), hip circumference, organized physical activity, and activity promoting bone mass, but negatively with the time devoted to sedentary activities and absolute carbohydrate intake (P<0.05). Age of menarche and years since menopause were negatively associated with QUS in the adult and elderly women, respectively (P<0.05). The latter relationship, however, was due to the confounding effect of advancing age. Overweight and obese females had significantly higher BUA and eBMD than normal-weight subjects (P<0.05), but similar SOS and QUI; this held true for all age groups. Likewise, in all ages, individuals spending more than 2 h/week on organized activities had significantly higher QUS indices than those spending less time on exercise (P<0.05). Further, postmenarchial girls had significantly higher age-adjusted BUA, SOS, QUI, and eBMD than premenarchial ones (P<0.05). Similarly, all QUS parameters were significantly higher in adult women with an early onset of menarche (<14 years old) than in those with a late onset (P<0.05), but no effects of menarche were detected among the elderly. No significant effects of calcium intake (which was generally adequate), smoking or alcohol drinking (which were generally low) on QUS indices were observed, in either age group. Available independent variables could explain approximately 16%-24% of the total variance in BUA, SOS, QUI and eBMD. The most important positive predictors of QUS were adulthood, time devoted to organized activities, and weight or BMI, while age and carbohydrate intake per se contributed negatively. In conclusion, age, body size, physical activity, and some aspects of reproductive history and diet appear to variably affect calcaneal QUS indices among otherwise healthy Greek women at different life stages.

Correlations between bone mineral density and demographic, lifestyle, and biochemical variables in community-dwelling Japanese women 69 years of age and over.

INTRODUCTION: A few epidemiologic studies have comprehensively attempted to identify risk factors for low bone mineral density (BMD) in elderly Asian women. The purpose of this study was to identify demographic, lifestyle, and biochemical factors correlated with BMD in elderly Japanese women 69 years of age and over. METHODS: The study design was cross-sectional. The subjects were 583 ambulatory women aged 69 years and over, and their average age was 74.3 (SD 4.4) years. Predictor variables were age, reproductive history, anthropometric indices, grip strength, calcium intake, lifestyle information, and serum 25-hydroxyvitamin D, 1,25-dihydroxyvitamin D (1,25(OH)(2)D), osteocalcin (OC), and undercarboxylated osteocalcin (ucOC) values. The outcome variable was forearm BMD measured with a DTX-200 osteometer. RESULTS: Simple linear regression analyses showed that BMD was significantly positively associated with body height, weight, body mass index, grip strength, serum albumin concentration, and "housework," and negatively associated with age, years since menopause, age at menarche, number of children, serum 1,25(OH)(2)D concentration, serum OC concentration, and ucOC concentration. The stepwise multiple regression analysis showed that weight (beta=0.00316, SE=0.00028, R(2)=0.180), age (beta=-0.00321, SE=0.00050, R(2)=0.108), log-transformed serum OC (beta=-0.0445, SE=0.0064, R(2)=0.053), log-transformed serum 1,25(OH)(2)D (beta=-0.0401, SE=0.0074, R(2)=0.050), "farmwork" (beta=0.00904, SE=0.00426, R(2)=0.005), and serum 25(OH)D concentration (beta=0.000281, SE=0.000120, R(2)=0.003) were significantly associated with BMD. CONCLUSION: It was concluded that body weight is a major predictor of forearm BMD among the factors measured in this study in independent Japanese women 69 years of age and over and that serum 1,25(OH)(2)D concentration may be associated with cortical BMD. Maintenance of body weight is very important for maintaining BMD in this population, unless a large weight aggravates obesity-related diseases. A follow-up study is needed to confirm these findings.

Factors related to variation in premenopausal bone mineral status: a health promotion approach.

Bone loss prior to menopause may contribute to later risk of fracture due to osteoporosis. Women may be able to optimize premenopausal bone mass and/or prevent losses. Heredity, and possibly age at menarche (retrospectively determined), are unmodifiable risk factors and attention should therefore be directed to more amenable factors. Amenorrhea, low body weight, disordered eating, and smoking are modifiable risk factors. Vitamin D is not a factor for premenopausal women who receive incidental sun exposure and consume fortified foods, but supplementation should be considered for others, especially during the winter months. Protective factors include a higher body weight (especially due to increased muscularity), calcium supplementation, and purposeful load-bearing exercise. Positive effects of oral contraceptives are most apparent in women with menstrual irregularities. Reproductive history (parity), lactation, moderate intakes of alcohol and caffeine, and the appropriate treatment of endometriosis have no apparent effect on premenopausal bone.

Lifestyle and biologic contributors to proximal femur bone mineral density and hip axis length in two distinct ethnic groups of premenopausal women.

Although relatively little is known about osteoporotic risk factors in women from the Indian subcontinent, osteoporotic fractures usually occur 10-20 years earlier in Indian men and women compared with their western Caucasian counterparts. The primary purpose of this cross-sectional study was to determine the relative contributions of ethnicity, reproductive history, body size (height, weight) and composition, bone turnover, serum 25(OH)vitamin D(3) [25(OH)D(3)], dietary intake (of calcium, fiber and alcohol) and energy expenditure to femoral bone mineral density (BMD) in Indian and Pakistani (Indian/Pakistani; n = 47) versus American (n = 47) Caucasians. We also contrasted femoral BMD and hip axis length in these two distinct groups of premenopausal females living in the USA. The Indian/Pakistani (0.875 +/- 0.096) women had lower (p = 0.0014) femoral BMD (g/cm(2)) than their American (0.937 +/- 0.088) counterparts, placing them at greater osteoporotic risk. However, the shorter (p = 0.0002) hip axis length (cm) of the Indian/Pakistani (10.54 +/- 0.57) versus American (11.11 +/- 0.78) Caucasians might attenuate hip fracture risk in the former group. Significant contributors to proximal femur BMD were maximum non-pregnant lifetime weight, age at menarche, ratio of summation sigma central-to-peripheral skinfold thicknesses, calcium intake from milk and usual alcohol intake. Although serum 25(OH)D(3) and urinary N-telopeptide concentrations did not contribute to femoral BMD in the regression models, the lower (p<0.0001) serum 25(OH)D(3) (33.1 +/- 16.5 vs 64.0 +/- 22.0 nmol/l) and higher (p = 0.0004) urinary N-telopeptide (45.9 +/- 43.3 vs 18.9 +/- 18.7 nmol BCE/mmol) values in Indian/Pakistani versus American Caucasians, respectively, coupled with their lower BMD, places the Indian/Pakistani women at greater osteoporotic risk. These results suggest that a clinical trial to increase BMD and reduce osteoporotic risk is warranted in this ethnic group of premenopausal women.

Determinants of bone mineral density and spinal fracture risk in postmenopausal Japanese women.

The present study analyzed the factors that determine bone mineral density (BMD) and predict spinal fracture risk in postmenopausal Japanese women. Two hundred and five postmenopausal Japanese women aged 48-84 years (mean age 64 years) were enrolled in the cross-sectional study. BMD of the lumbar spine, femoral neck and total body as well as body composition were measured by dual-energy X-ray absorptiometry (DXA). Mid-radial BMD was measured by single-photon absorptiometry. We also determined serum levels of insulin-like growth factor (IGF)-I, IGF binding protein-2, -3 and osteocalcin as well as urinary levels of pyridinoline (Pyr), deoxy-Pyr (D-Pyr) and growth hormone. Multiple regression analysis revealed that lean body mass (LBM) was positively correlated with BMD at all sites. In contrast, femoral neck BMD was highly related to fat mass as well as LBM, although fat mass was not an independent correlate of total body and mid-radial BMD. LBM and urinary D-Pyr were crucial determinants at all sites except the mid-radius in stepwise regression analysis. Fat mass and serum IGF-I were determinants of femoral neck and mid-radial BMD, respectively. In terms of reproductive history, parity affected lumbar BMD. Factors affecting BMD differed according to the site. On the other hand, lumbar BMD as well as serum levels of IGF-I and albumin were selected as predictors of spinal fracture risk in multiple logistic regression analysis. Lumbar BMD, serum IGF-I and LBM were selected in women with lumbar BMD above 0.727 g/cm2. In conclusion, the present study indicates that LBM is a more important determinant of BMD than fat mass at any site except the femoral neck. Age, serum IGF-I and urinary D-Pyr were also determinants of BMD, dependent on the regions measured. Lumbar BMD and LBM as well as serum levels of IGF-I and albumin were useful markers which predicted the risk of osteoporotic spinal fractures in postmenopausal Japanese women.

A strong association between body fat mass and protein profiles in nipple aspirate fluid of healthy premenopausal non-lactating women.

Fluid can be aspirated from the nipples of most non-lactating women. This nipple aspirate fluid (NAF) is a potential source for the discovery of new breast cancer biomarkers. NAF has two distinct protein profiles. Type I NAF is similar to the fluid associated with cystic disease of the breast, whereas type II NAF is enriched in milk-associated proteins. The prevalence of these two profiles differs in healthy women and in breast cancer patients. This study investigated the relationship of these two NAF profiles to reproductive history, body composition, diet, and levels of lipids, steroids and thyroid hormones in healthy premenopausal women (age 30-40 years) who had regular menstrual cycles and normal mammograms and were not taking contraceptive medications. On average, women with the type I NAF profile were older, had more years since last childbirth, were less likely to have breastfed their babies and had higher dietary saturated fat intake, body mass index, body fat mass, and levels of plasma low density lipoproteins than women with the type II profile (P <0.05). Using multiple logistic regression, type I NAF was predicted independently (P <0.05) by higher body fat mass [Odds Ratio (OR) = 3.0; 95% Confidence Interval (CI): 1.5-6.1], more years since last childbirth (OR = 2.6; 95% CI: 1.3-5.2) and a higher percentage of calories from saturated fat (OR = 4.1; 95% CI: 1.1-14.6). These results suggest that protein profiles of NAF might be influenced by amounts or types of dietary and body fat, but further study of the relationship of the two profiles to breast cancer risk is needed.

Subfertility and the risk of testicular germ cell tumors (United States).

OBJECTIVES: Previous studies have reported an association between subfertility and the risk of testicular germ cell tumors. We examined fertility, measured by number of children fathered and prior diagnosis of infertility, as a risk factor for testicular cancer, while accounting for the influence of occult cancer and cryptorchidism. METHODS: Tumor registry data were used to identify 329 cases of testicular cancer in white men aged 20 to 69 years, diagnosed in western Washington State from 1977 to 1983; 672 cancer-free controls were identified by random-digit dialing. Telephone interviews ascertained reproductive histories and basic demographic information. Logistic regression was used to estimate the relative risk of testicular cancer associated with fertility. RESULTS: Testicular cancer risk was decreased among men who had previously fathered a child (age-adjusted odds ratio (OR) 0.76, 95% confidence interval (CI): 0.54-1.06). Inverse associations were seen for seminomas and non-seminomas, and only slight attenuations in the ORs were observed when men with a history of cryptorchidism were excluded. Prior diagnosis of infertility was associated with an increased risk of testicular cancer (OR 2.40, 95% CI: 1.00-5.77). CONCLUSIONS: These results are consistent with an increased risk of testicular cancer among men with reduced fertility that goes beyond the effects of cryptorchidism.

Maternal pregnancy loss, birth characteristics, and childhood leukemia (United States).

OBJECTIVE: The authors evaluated the relation between maternal pregnancy loss, birth characteristics, and childhood leukemia in the Northern California Childhood Leukemia Study. METHODS: Incident cases of childhood leukemia (age 0-14 years) were rapidly ascertained, and controls were randomly selected from birth records and individually matched to cases. A total of 366 cases [313 acute lymphoblastic leukemia (ALL) and 53 acute myeloid leukemia (AML)] and 460 controls were included in this analysis. The biological mothers of all subjects provided detailed reproductive history and birth characteristics of the index children during a personal interview. Odds ratio (OR) and 95% confidence intervals (CI) were estimated using conditional logistic regression. Data on maternal pregnancy loss and birth characteristics were also available from the birth certificates of 96.3% of all subjects. RESULTS: History of miscarriage was associated with a significantly increased risk of AML (OR = 2.94, 95% CI: 1.03, 8.34), but not ALL. Neither birth weight, birth order, or parental ages appeared to be an important predictor of the risk of ALL or AML. A comparison between data from two different sources (interview versus birth certificate) indicated good reproducibility and offered some evidence against recall bias. CONCLUSION: Maternal history of miscarriage is associated with an increased risk of childhood AML.

Smoking as a determinant for plasma levels of testosterone, androstenedione, and DHEAs in postmenopausal women.

The aim of the present study was to investigate whether current smoking, ex-smoking, or amount of current smoking among postmenopausal women was associated with plasma levels of testosterone, and rostenedione, and DHEAs. About 65,000 women in Sweden have participated in two population-based prospective cohort studies where blood samples were collected at baseline, and information on life-style, reproductive history and anthropometrical measurements were available. The present study was based on 407 control subjects from a previous nested case-control study on the relation between steroid hormone levels and risk of breast cancer. A multivariate logistic regression analysis, adjusted for potential confounders, was used in order to obtain odds ratios (OR) with 95% confidence intervals. There was a high risk of high testosterone levels (above the median) in current vs. never smokers, OR: 1.85 (1.06-3.23). Risk of high testosterone levels increased by amount of daily smoking (increments of 10 cigarettes/day), OR: 1.55 (1.02-2.37). Ex-smoking was associated with high testosterone levels, OR: 1.56 (0.98-2.47). Current smoking and increasing amount of current smoking were weakly associated with high androstenedione levels. However, these associations did not reach statistical significance. No association was seen between smoking habits and DHEAs levels. We conclude that current smoking, and increasing amount of daily smoking, is associated with high testosterone levels.

Risk factors for hip fracture and a possible effect modification by hormone replacement therapy. The Danish nurse cohort study.

OBJECTIVE: To identify risk factors for hip fracture and to examine whether hormone replacement therapy (HRT) modifies the effect of these risk factors. DESIGN: Prospective cohort study. SETTING: The Danish Nurse Cohort Study. PARTICIPANTS: 14,015 female nurses aged 50 years and above who in 1993 completed a questionnaire on general health and lifestyle issues, reproductive history including information on HRT, and family history of osteoporosis and personal history of a wrist fracture. OUTCOME MEASURES: End-point was the first-ever hip fracture registered in the Danish National Hospital Register during the period from 1993 to 1999. RESULTS: During the follow-up period 245 hip fractures were identified. Ever users of HRT had a lower risk of hip fracture (hazard ratio 0.69; 0.50-0.94). Women reporting a poor health (hazard ratio 2.01; 1.30-3.11), restrictions in daily activities (hazard ratio 1.52; 1.05-2.21), low body mass index (hazard ratio 1.65; 0.98-2.77), and leisure time sedentary physical activity (hazard ratio 1.88; 1.30-2.70) were main identified risk factors for hip fracture. HRT did not modify the effect of risk factors on the risk of hip fracture. CONCLUSION: This study confirms that women with a frail health are at increased hip fracture risk and that ever use of HRT decreases the risk of hip fracture. HRT did not modify the effect of these risk factors, indicating that the preventive effect of this therapy is independent of risk factors.

Pregnancy and stem cell behavior.

The identification of cancer-initiating epithelial subtypes (i.e. cancer stem cells) is important for gaining a more comprehensive understanding of the process of neoplastic transformation and tumorigenesis. Since reproductive history has a major impact on breast tumorigenesis, it is reasonable to assume that pregnancy and lactation have enduring effects on the cancer susceptibility of multipotent progenitors. Using the Cre-lox technology as a tool to genetically label pregnancy-hormone-responsive cells, we identified a mammary epithelial subtype that is abundant in parous females. These pregnancy-induced mammary epithelial cells (PI-MECs) originate from differentiating cells during the first pregnancy and lactation cycle. They do not undergo apoptosis during postlactational remodeling, and they persist throughout the remainder of a female's life. In this review, we discuss the biological relevance of PI-MECs in multiparous females and their important stem cell-like features, such as self renewal, as well as their ability to produce progeny with diverse cellular fates. Using appropriate animal models, we further demonstrate that PI-MECs are cellular targets for pregnancy-enhanced mammary tumorigenesis.

Fertility in women with gonadal dysgenesis.

A successful pregnancy in a patient with a 45,X/47,XXX karyotype who had premature menopause is described. Review of the literature revealed an additional 24 cases of fertility in women with gonadal dysgenesis associated with a 45,X chromosomal line. Their reproductive history showed a total of 58 pregnancies. However, abortion, stillbirth, and abnormal progeny, including five with chromosomal errors, were common. Therefore, such patients should be advised regarding their reduced fertility potential and the possibility of abnormal offspring.

The association of maternal floor infarction of the placenta with adverse perinatal outcome.

Maternal floor infarction of the placenta is a relatively rare disorder that on gross examination is characterized by a thickened gray-yellow maternal floor of the placenta with histologic evidence of massive fibrin deposition involving the decidua basalis and the contiguous villi. This lesion has been associated with fetal death, preterm delivery, and intrauterine growth retardation and is thought to be recurrent. Sixty cases of maternal floor infarction were identified in 48 women. Fetal death occurred in 24 of the 60 cases (40%). Preterm birth occurred in 21 of 36 (58.3%) live-born infants, and 19 of the 35 (54.2%) live-born infants for whom a birth weight was known had evidence of intrauterine growth retardation. Among the 41 multiparous patients in our series there were five documented recurrences (12.2%). Review of the past reproductive history of these 48 patients (196 pregnancies) demonstrated a significant incidence of fetal death (24.1%), intrauterine growth retardation (31.3%), and preterm death (35.4%). The association of fetal death and maternal floor infarction emphasizes the importance of a placental examination with all cases of fetal death and infants with intrauterine growth retardation. Given the risk of recurrence, the identification of maternal floor infarction should alert the clinician to the potential for growth retardation, preterm birth, and fetal death in subsequent pregnancies.
