A fifth-month fetus and a newborn with amniogenic band anomalies were examined at autopsy. Both specimens were obtained from women who had undergone oophorectomy during early pregnancy. The dead male fetus was aborted spontaneously, and had a micrognathia, a right club foot, and a constriction ring on the left lower leg. The left fingers 2, 3, and 4 were attached to the placenta by a fibrous string. No internal anomaly was noted. In the other case, a male newborn was delivered at the 39th week of gestation and had an agenesis of the calvarium, a cleft lip with palate, an amputation of the right toe, and constriction rings on right fingers 3 and 4 and left finger 3. The placenta was attached to the left temporooccipital region of the head by a fibrous string. Also present was an atrial septum defect and a horseshoe kidney. Possible etiology is discussed in relation to the "amniogenic bands" hypotheses.  相似文献

Oculo-auriculo-vertebral (OAV) spectrum or Goldenhar syndrome is a complex and heterogeneous condition characterized by hemifacial microsomia (unilateral ear abnormalities and ipsilateral mandibular hypoplasia) as well as vertebral anomalies and epibulbar dermoids or lipodermoids. Although most cases of OAV spectrum are sporadic, both autosomal recessive and autosomal dominant inheritance have been reported. Furthermore, the association of OAV spectrum with different types of chromosomal abnormalities has been described. We present a premature newborn delivered after 36 weeks of gestation, whose birth weight was 2,100 g, birth length 43 cm and head circumference 32.5 cm. OAV spectrum with associated axial skeleton anomalies, eventration of the right hemidiaphragm, accessory spleen, unlobulated right lung, agenesis of right kidney, right ovary and right uterine horn, and partial agenesis of corpus callosum were found. She was the second child of unrelated parents, who have a healthy boy. Both parents refused chromosomal analysis of their peripheral blood. Trypsin G-banding and C-banding chromosomal analysis of the patient's peripheral blood revealed a pericentric inversion of chromosome 9 with break points at p11 and q13. This may be a coincidental or causal finding.  相似文献

Eight patients with severe rhesus disease and expected fetal loss were treated by intensive plasmapheresis using a continuous-flow cell separator. Plasmapheresis was started at 16-27 weeks'' gestation, and continued until planned intrauterine transfusion or until the infant was delivered or the rhesus disease became uncontrolled again. Altogether 24 to 2371 of plasma was exchanged over periods ranging from seven to 16 weeks. In seven of the eight patients the anti-D concentration fell during the period of plasmapheresis. Amniotic fluid spectrophotometry values remained below those recorded in the preceding pregnancy in six out of seven women. In five patients an attempt was made to control the rhesus disease by plasmapheresis alone, and two of these women delivered infants who survived. In the other three cases the infants died, one from the idiopathic respiratory distress syndrome and the other two in utero. These preliminary findings suggest that intensive plasmapheresis with a cell separator may reduce fetal haemolysis is delivered. Nevertheless, plasmapheresis may best be used to reduce haemolysis until intrauterine transfusions may be given more safely after 30 weeks'' gestation.  相似文献

Data concerning pregnancy in women with Cushing's disease treated by gamma-knife (GK) are scanty. We present and discuss the course and outcome of five pregnancies in two women with Cushing's disease (CD), the first of whom was treated only by GK, and the second one treated by surgery, GK and ketoconazole. In the first patient, pregnancy was uneventful and full-term. During gestation, plasma ACTH, serum cortisol and 24-h urinary free cortisol (UFC) levels were steady, and always in the normal range for healthy non-pregnant individuals. The newborn was healthy and normal-weight. In the second woman, two pregnancies, occurring 3 years after GK and few months after ketoconazole withdrawal, were interrupted by spontaneous abortion or placental disruption despite normal cortisol levels. This patient became again pregnant 3 years later and delivered vaginally a healthy full-term infant. Seven months after the delivery, the patient became pregnant again and at the 39th week of gestation delivered vaginally a healthy male. Hypoprolactinemia and/or central hypothyroidism occurred in both cases. In women with CD treated by GK, pregnancy can occur. However, pregnancy is at risk even when ACTH and cortisol levels are normalized by treatment. After GK, evaluation of pituitary function is mandatory due to the risk of hypopituitarism.  相似文献

Oculoauriculovertebral spectrum or Goldenhar syndrome is a phenotypically and probably genetically heterogeneous disorder characterized by hemifacial microsomia (unilateral ear abnormalities and ipsilateral mandibular hypoplasia) as well as vertebral anomalies and epibulbar dermoid/lipodermoids. Although most cases of the Goldenhar syndrome are sporadic, both autosomal recessive and dominant inheritance have been reported so far. In this report, we describe the clinical aspects of two familial cases with evidence of autosomal dominant inheritance and a non-familial case, and compare them with the reports in the literature. One of our familial cases was a ten day old female infant of a mother with left hemifacial microsomia. She had multiple bilateral preauricular tags and a "fleshy masse" on her right cheek. The other familial case was a two months old male infant whose father had hemifacial asymmetry. He had unilateral microtia, and abnormal antihelix, a skin tag in the contralateral ear associated with bilateral sensorineural hearing loss. The third case was a sporadic case who was 2 years old boy with preauricular skin tag, right hemifacial microsomia and limbal dermoid at the temporal limbus of the right eye. As there were no other associated defects, the cases we presented here were thought to be mild variations of the Goldenhar spectrum. The most commonly encountered mutations of thrombophilia genes were studied. We believe that the interfamilial and intrafamilial clinical variabilities observed in these cases reinforce the necessity of a careful examination for the whole family with regards to the stigmata of Goldenhar syndrome.  相似文献

Warfarin, which is used for anticoagulant therapy, rarely produces congenital warfarin syndrome characterized with hypoplastic nose, stippled epiphyses, and skeletal abnormalities when ingested during pregnancy. Here, we present a male infant, whose mother was treated with warfarin because of a prosthetic heart valve replacement after rheumatic heart disease, with signs of warfarin embryopathy. The mother's first pregnancy at 12 weeks gestation resulted in abortus due to warfarin toxicity. Subsequently, she delivered two healthy girls after her treatment had changed to low molecular heparin during pregnancy periods. We want to emphasize that risk-benefit ratio should be well weighed by both obstetricians and cardiologists when considering warfarin therapy for a woman at childbearing age.  相似文献

A non-resident male attacked a 4-month-old unweaned infant in a free-ranging group of Japanese macaques (Macaca fuscata) and it died 2 days later from a severe wound. When the infant was alone at the feeding site, the non-resident male rushed at it. The infant ran away as soon as it became aware of the male, but was captured. The male bit the infant on its hand, foot, and arm, while continuously scanning his surroundings. He did not kill the infant immediately and, after the infant escaped, he did not chase or attack it at all. Although the infants right arm was bleeding heavily, it survived until the following day. The infanticide occurred a few weeks before the mating season began, so the victims mother soon resumed estrus and the subsequent inter-birth interval was shortened. The first-, second-, and fourth-ranking adult males had died or disappeared a few months before this infanticide, and there were no other group members near the infant when the infanticidal male appeared. The infanticidal male had not been observed before this incident. Compared to one-male groups, the occurrence of infanticide in multi-male groups of Japanese macaques is extremely infrequent. However, in other reports of infanticide in Japanese macaques as well as in this case, it has been noted that infanticide is likely to occur in the pre- or early-mating season, when there are no resident males to defend the infant against attacks, and when a threatening male is least likely to be the infants father.Electronic Supplementary Material Supplementary material is available for this article at  相似文献

Background

We describe two cases of dichorionic triplet pregnancy after a frozen-thawed poor-stage embryo transfer.

Main body of the abstract

A 39-year-old and a 41-year-old woman underwent ART treatment. The first patient underwent intracytoplasmic sperm injection (ICSI) at 34 years of age, and two frozen-thawed poor-stage embryos were transferred at 39 years of age with assisted hatching, resulting in a trichorionic triamniotic triplet pregnancy. The second patient underwent ICSI, and two poor-grade blastocysts were transferred followed by assisted hatching, resulting in a dichorionic triamniotic triplet pregnancy.In the first case, the heartbeat of one monozygotic twin fetus had stopped on day 48 post-transfer (9 weeks 2 days), resulting in a dichorionic diamniotic twin pregnancy. A healthy boy and girl were delivered by elective caesarean section at 36 weeks, 5-days gestation. In the second case, the patient underwent selective reduction of the monochorionic twins, resulting in a single pregnancy that was vaginally delivered without any problems at 38 weeks 0-days gestation.

Short conclusions

Numerous factors may be associated with the development of a monochorionic pregnancy; however, controversies still remain. The present morphological grading for embryos is insufficient for inhibiting the development of a monochorionic pregnancy.

BACKGROUND: We report a successful pregnancy in a woman with severe ovarian dysfunction and infertility associated with a variant beta-subunit of luteinizing hormone (LH). METHOD/OUTCOME: A 35-year-old woman consulted our unit for infertility. Laparoscopy and ultrasonography showed obstruction of the right tube and ovulation from the right ovary only. Human menopausal gonadotrophin (hMG) therapy was used for six subsequent cycles, but did not result in conception. Subsequently, marked elevation of follicle-stimulating hormone (FSH) and testosterone, together with polycystic ovary (PCO) were noted. The patient failed to respond to ovarian stimulation by hMG. Severe ovarian dysfunction such as premature ovarian failure (POF) was strongly suspected. Sequence analysis of the LH beta-subunit gene indicated heterozygosity for point mutations Trp(8) to Arg(8) and Ile(15) to Thr(15) in the coding sequence. LH hypersecretion resembling that seen in PCO syndrome was observed. Induction of ovulation by hMG was successful in the first cycle in which the basal LH and FSH were well controlled with gonadotrophin-releasing hormone analog following estrogen-progesterone replacement. She conceived and delivered a healthy male infant at term. CONCLUSION: Clinicians should be clinically aware of patients with immunologically anomalous LH variant who might be at risk of developing ovarian failure within a relatively short time span. Pertinent treatment should be applied without delay in such cases.  相似文献

We present the autopsy report of a liveborn triploid female, born after 36 weeks of gestation, who died at the age of 20 hours. External features were diagnostic: fetal hypoplasia, hypertelorism, microstomia, micro-and retrognathia, preauricular skin tag, low-set ears, and 3-4 syndactylia. All internal organs were hypoplastic. There were atrial and ventricular septal defects. Adrenals and kidneys were fused, the gallbladder was absent, and ovarian hilum cell were found to be hyperplastic. Triploidy, 69xxx, was confirmed cytogenetically. The placenta was hypoplastic and, microscopically, revealed a peculiar type of immaturity, so-called hydatidiform villous hypoplasia, findings which have not been previously reported. We suggest that the generalized fetal and placental hypoplasia and the severe hypoplasia of all internal organs are caused by a proliferative deficiency of the triploid cells. In addition, the nuclear DNA content was determined by cytophotometrically from placental stromal cells and was found to be about 50% above the normal diploid DNA value; i.e., a triploid DNA value was confirmed.  相似文献

Cytogenetic analysis of germ-line cells prior to intracytoplasmic sperm injection (ICSI) treatment is thought to be necessary for infertile males with an identified chromosomal abnormality. We analyzed the chromosomal karyotype of human spermatozoa from an oligoasthenozoospermic carrier of a reciprocal translocation t(10; 21). Cytogenetic analysis of 39 spermatozoa was performed by spectral karyotyping (SKY) and by ICSI into mouse oocytes. The motile morphologically normal spermatozoa were injected into mouse oocytes. Of these spermatozoa, 38 (97.4%) were activated. Twenty-one (53.8%) of the activated oocytes formed two pronuclei. Metaphase chromosome spreads from 13 spermatozoa were analyzed. Only one spermatozoon was normal and 2 spermatozoa exhibited balanced translocation. Nine and one spermatozoa showed abnormalities related and unrelated to the translocation, respectively. The numbers of normal/balanced spermatozoa were lower than those in previous reports analyzing reciprocal translocations using a previously described technique involving penetrated golden hamster oocytes. After genetic counseling with the carrier and his partner, ICSI treatment was performed. Healthy female and male infants were delivered at 37 weeks gestation via a Caesarean section. The female infant was a carrier of the reciprocal translocation and the male infant was confirmed normal on prenatal diagnosis at 16 weeks gestation. For genetic counseling prior to ICSI treatment, the incidence of unbalanced type spermatozoa after swim-up or Percoll gradient treatment should be investigated and discussed with couples having fertility problems related to oligozoospermia autosomal structural abnormalities.  相似文献

Acrocallosal Syndrome is a rare genetic disorder which is characterized by moderate to severe mental retardation, agenesis or hypoplasia of the corpus callosum and polydactyly of fingers and toes. The spectrum of this syndrome is very variable. Prominent forehead, broad nasal bridge, short nose and mandible, hypertelorism, epicanthic folds, large anterior fontanelle and tapered fingers, omphalocele and inguinal hernia are some other common findings in this syndrome. Twenty percent of the patients have associated brain abnormalities such as cerebral atrophy, hypothalamic dysfunction, small cerebrum, micropolygyria, hypoplasia of pons, hypoplasia of cerebellar hemispheres, hypoplasia of medulla oblongata, agenesis or hypoplasia of cerebellar vermis and corpus callosum abnormalities. Here we present a 10-month-old female infant with clinical and radiological findings indicative of acrocallosal syndrome. She was noted to have craniofacial abnormalities suggestive of acrocallosal syndrome, optic atrophy and polydactyly. MRI revealed cerebral atrophy, corpus callosum agenesis, dilated lateral ventricules and unilateral right temporal lobe hypoplasia, the latter not previously reported in the spectrum of this syndrome. Based on this observation we conclude the importance of screening brain abnormalities and present temporal lobe hypoplasia as a new additional anomaly in this syndrome.  相似文献

A 30-year-old woman contracted Plasmodium falciparum malaria in the first trimester of her pregnancy while taking chloroquine for malaria prophylaxis. Her illness was characterized by hemolytic anemia with IgG1 coating of the surface of the erythrocytes and IgG3 in her serum. The hemolysis subsided following treatment of the malaria infection early in the third trimester. She delivered at term an infant who had hypoplasia of the right tibia and fibula and absence of the fifth ray of the right foot. The hemolytic process was attributed to the malaria infection, and the birth defect may have been related to the antimalarial therapy in the first trimester of pregnancy.  相似文献

Infants with congenital craniofacial malformations often have associated severe mandibular hypoplasia causing obstruction of the hypopharynx by retroposition of the base of the tongue into the posterior pharyngeal airway. Management depends on the severity of the airway obstruction. Most cases can be managed by prone positioning until the infant outgrows the problem at 3 to 6 months of age. In more critical cases, monitoring of oxygen saturation, temporary placement of a nasopharyngeal tube, and placement of an endotracheal tube will be useful procedures. Tracheotomy is an effective method for more severe cases, but longstanding tracheotomies result in high morbidity and occasional mortality. Mandibular distraction was performed in seven patients, ranging in age from 1 to 18 months, with critical obstructive apnea secondary to mandibular hypoplasia characterized by an apnea/hypopnea index greater than 20 apneas per hour and oxygen saturation below 80 percent. Two patients were tracheotomized previously. Mandibular lengthening, from 16 to 25 mm on the left side and from 10 to 22 mm on the right, was achieved in 21 to 25 days. Improvement of airway obstruction parameters was measured on polysomnograms and lateral cephalograms. Mandibular lengthening by gradual distraction is a successful method for young patients with severe mandibular hypoplasia causing critical obstructive apneas. Avoidance of tracheotomy or early decannulation in previously tracheotomized patients is a great advantage for patients with congenital craniofacial malformation.  相似文献

Secretory component (SC) is a phospholipase A2 inhibitor possibly associated with pregnancy maintenance and in serum is bound either to IgA (sIgA) or IgM (sIgM). To determine if serum secretory component levels a) increase during pregnancy, b) fall as term approaches, c) are low in women who will deliver prematurely, serum sIgA was measured at "booking in" and related to weeks of gestation and length of gestation at subsequent noninduced delivery. Levels of sIgA increased during pregnancy; sIgA increased from a non-pregnant value of 1.6 nM +/- 0.2 (mean +/- SEM) to 2.8 nM +/- 0.3 at the end of the second trimester, then fell significantly between 31-34 weeks. Delivery before 37 weeks was associated with significantly reduced serum sIgA levels, particularly in women who delivered before 32 weeks and in whom sIgA concentrations were similar to those of nonpregnant women.  相似文献

ABSTRACT: BACKGROUND: Viral infections during pregnancy can pose serious threats to mother and fetus from the time of conception to the time of delivery. These lead to congenital defects, spontaneous abortion and even death. The definitive diagnosis and management of pregnancy-related viral infections may be challenging especially in less resourced countries. CASE PRESENTATION: We present clinical and laboratory responses to the diagnosis and management of three cases of fulminant hepatitis secondary to Hepatitis E viral infection in pregnancy.Case 1 was a 31-year-old Ghanaian woman who presented with a week's history of passing dark urine as well as yellowish discoloration of the eyes. She subsequently developed fulminant hepatitis secondary to Hepatitis E viral infection, spontaneously aborted at 24 weeks of gestation and later died.Case 2 was also a 31-year-old Ghanaian woman who was admitted with a four-day history of jaundice. She had low grade fever, but no history of abdominal pain, haematuria, pale stool or pruritus. She next developed fulminant hepatitis secondary to Hepatitis E viral infection. However, she did not miscarry but died at 28 weeks of gestation.Case 3 was a 17-year-old Ghanaian woman who was referred to the tertiary health facility on account of jaundice and anaemia. She had delivered a live male infant at maturity of 32 weeks but noticed she was jaundiced and had a presentation of active disease 3 days prior to delivery. The baby was icteric at birth and on evaluation, had elevated bilirubin (mixed type) with normal liver enzymes. Hepatitis E virus infection was confirmed in both mother and baby. However, the jaundice and the hepatomegaly resolved in mother and baby after 5 and 12 days respectively. CONCLUSION: To the best of our knowledge, these are the first documented cases of fatal fulminant hepatic failures resulting from HEV infection in Ghana.  相似文献

We describe a successful cardiac intervention in an infant, born at 32 weeks of gestation, with a birth weight of 1040 g, who had a critical pulmonary valve stenosis with the right ventricular pressure twice the systemic pressure. Continuous prostaglandin E infusion kept the arterial duct open and at the age of four weeks and a weight of 1500 g a balloon valvuloplasty was performed, which reduced the systolic right ventricular pressure to below the systemic pressure. Two weeks later the procedure was repeated because of increasing right ventricular pressure. At two months of age the mean systolic transpulmonary Doppler gradient was 30 mmHg with an adequate right ventricular volume. The neurological status of the infant was normal and the femoral vein was patent. Timely interventional heart catheterisation is a successful method of treatment in critical pulmonary valve stenosis in infants with a low birth weight. (Neth Heart J 2008;16:264-6.)  相似文献

The purposes of this study were to determine the intervals when placental corticotrophic-releasing hormone (CRH) was most responsive to maternal cortisol. A sample of 203 women each were evaluated at 15, 19, 25 and 31 weeks gestation and followed to term. Placental CRH and maternal adrenocorticotropin hormone (ACTH), B-endorphin and cortisol were determined from plasma. CRH levels increased faster and were higher in women who delivered preterm compared with women who delivered at term (F3,603 = 5.73, p < .001). Simple effects indicated that CRH levels only at 31 weeks predicted preterm birth (F1,201 = 5.53, p = .02). Levels of cortisol were higher in women who delivered preterm at 15 weeks gestation (F1,201 = 4.45, p = .03) with a similar trend at 19 weeks gestation. Hierarchical regression suggested that the influence on birth outcome of maternal cortisol early in pregnancy was mediated by its influence on placental CRH at 31 weeks. Elevated cortisol at 15 weeks predicted the surge in placental CRH at 31 weeks (R = .49, d.f. = 1,199, Fchange = 61.78, p < .0001). Every unit of change in cortisol (microg/dl) at 15 weeks was associated with a 34 unit change of CRH (pg/ml) at 31 weeks. These findings suggested that early detection of stress signals by the placenta stimulated the subsequent release of CRH and resulted in increased risk for preterm delivery.  相似文献

Acholeplasmas have been isolated from a variety of animals, insects, and plants, but onlyAcholeplasma laidlawii has previously been found in humans. We have isolatedAcholeplasma oculi in pure culture from the amniotic fluid of a woman at 19 weeks of gestation. The organism was positively identified by growth inhibition, epi-immunofluorescence, and arbutin hydrolysis. Demonstration of organisms directly in amniotic fluid by DNA fluorochrome and immunofluorescence staining provided additional evidence that the isolate was genuine and not a medium contaminant. The remainder of the pregnancy was unremarkable, and a full-term male infant was delivered without complications. Even though there is some evidence possibly associatingA. oculi with various diseases in livestock, the prevalence and significance ofA. oculi in humans has not been determined.  相似文献
