Early prenatal detection of a fast-growing fetal epignathus.

Epignathus is a rare congenital orofacial teratoma. We present a case of a fast-growing tumor, where early prenatal diagnosis was made and where fetopathological examination revealed the reason of the remarkable ultrasonographic signs and underlined the expected poor prognosis. Ultrasonographic examination at 18 weeks' gestation showed that there was a growing tumor protruding from the fetus's mouth.

[Pentalogy of Cantrell: six new cases].

Unlabelled: Cantrell's pentalogy is a rare multiple malformation syndrome consisting of supraumbilical abdominal wall defect, sternal defect, pericardial defect, anterior diaphragmatic defect and heart malformation.

Aims And Methods: Prenatal ultrasound findings and malformations described during autopsy of the Cantrell's pentalogy cases diagnosed between January 1991 and June 2009 in our institute were reviewed. A literature research was conducted to analyze the prevalence and prenatal detection rate of the five previously described malformations and ectopia cordis in the Cantrell's pentalogy cases.

Prenatal diagnosis and fetopathological investigation of dorsolumbosacral agenesis.

Sacral and lumbosacral spine agenesis, as characteristic signs of a rare congenital malformation--caudal regression syndrome--has been well described. However, dorsolumbosacral agenesis involving the lower thoracic, lumbar, and sacral vertebrae has rarely been reported, and prenatal diagnosis of this severe form has not been published yet. A 37-year-old woman (gravida 2, para 0) who had diabetes mellitus asked for termination of her pregnancy, because second-trimester ultrasound screening showed dorsolumbosacral agenesis of the fetus.

Circulating antibodies to a conserved epitope of the Chlamydia trachomatis 60-kDa heat shock protein is associated with decreased spontaneous fertility rate in ectopic pregnant women treated by salpingectomy.

Problem: This prospective study was aimed to evaluate whether non-invasive clinical and serologic parameters of tubal disease are predictive for subsequent spontaneous conception and pregnancy outcome after first episode of ectopic pregnancy (EP).

Method Of Study: Overall, 144 women aged <35 years were enrolled. Outcome of subsequent spontaneous conception was analyzed after 3 years and compared with clinical parameters and antibody responses to Chlamydia trachomatis and epitopes of the 60-kDa chlamydial heat shock protein (CHSP-60).

Effect of hormone replacement therapy on postmenopausal endometrial bleeding.

The aim of the study was to determine the effect of postmenopausal hormone replacement therapy (HRT) (treatment using estrogen only and sequential and continuous combined estrogen-progestogen treatment) on endometrial bleeding and histological changes of the endometrium. In a six-year period (2000-2005), 5893 patients were given care and the incidence of postmenopausal uterine bleeding was detected in groups of patients having and not having received hormonal treatment at the Menopause Outpatient Unit of the authors' department. In the case of bleeding, fractioned abrasion was performed and the samples were analyzed histologically.

Prenatally diagnosed fetal brain injuries with known antenatal etiologies.

Periventricular leukomalacia of pre- or postnatal onset is responsible for severe neurological and intellectual impairment and cerebral palsy later in life. The etiology is multifactorial, involving hypoxic-ischemic insults of various origin. The disorder is characterized by multiple necrotic foci of the white matter found most frequently adjacent to the lateral ventricles.

[Analysis of the dopamine D4 receptor gene variants in attention deficit hyperactivity disorder].

The human dopamine D4 receptor (DRD4) gene has been extensively studied as a candidate gene for attention deficit hyperactivity disorder (ADHD). Both the 5' regulatory region and the coding sequence contain a number of polymorphisms. The most widely investigated polymorphism of the DRD4 gene is the 48 bp VNTR (Variable Number of Tandem Repeats) in the third exon.

[The effect of postmenopausal hormone replacement therapy on endometrial bleeding].

Association between the 120-bp duplication of the dopamine D4 receptor gene and attention deficit hyperactivity disorder: genetic and molecular analyses.

Abnormalities of the dopamine neurotransmission have been hypothesized to play an important role in the pathophysiology of attention deficit hyperactivity disorder (ADHD). Promoter variants of the dopamine D4 receptor gene (DRD4) have attracted particular interest due to their possible role in regulation of gene transcription. Here we describe the haplotype analysis of the 120 base pair duplication (120-bp dup) and three SNPs (-616C/G, -615A/G, -521C/T) in the 5' region of the DRD4 gene among children with ADHD.

[Congenital absence of the ductus venosus associated with severe congenital heart malformation--case report and review of the literature].

Congenital absence of the ductus venosus is a rare anomaly. The authors have found 57 cases in the literature. Their case was associated with a complex congenital heart disease, what occurs only in 10% of absent ductus venosus cases.

[Improved outcome with sirolimus-cyclosporine regimen in high-risk renal transplant recipients].

Aim: The immunosuppressive agents have a broad spectrum of adverse effects. In the absence of selective and specific drugs the decrease incidence and severity of side effects can be achieved by the combination of synergistic drugs only. Without wise selection and use of the combination of the potent immunosuppressive agents for the immunosuppressive maintenance therapy better results cannot be achieved without or fewer toxicities particularly in high-risk patients who lose their grafts prematurely.
