PROBLEM: Granulysin (GNLY) is a cytotoxic molecule mostly present in decidual natural killer (NK) cells. Blighted ovum (BO) and missed abortion (MA) represent the early pathological pregnancies with hindered development of the embryoblast or a dead embryo. We investigated the GNLY-mediated apoptotic mechanism potentially responsible for delayed termination of pregnancy. METHOD OF STUDY: We performed immunohistological and immunofluorescence labeling of decidual tissues (GNLY, Apaf-1, NF-κB)...

BACKGROUND: Heterotopic pregnancies are rare in spontaneous conceptions. Nonetheless, when it does occur, the intrauterine pregnancy is usually viable. We herein present a true rarity of the coexistence of a blighted ovum and an ectopic pregnancy. CASE PRESENTATION: A 25 year old G2P1001 married seamstress of African ethnicity at 8 weeks of amenorrhoea presented to our health facility with a 4 day history of lower abdominal pains and vaginal bleeding for which physical examination revealed a closed cervix...

BACKGROUND: Blighted ovum is one of the most common reasons for abortion during the first three months of pregnancy. Manganese superoxide dismutase (MnSOD) is an important antioxidant enzyme in the human immune system. The gene is located on 6q25 chromosome and acts on mitochondrial matrix. In the case of mutation or inactivity of this enzyme, mitochondrial and nuclear DNA will severely be destructed. The most common polymorphism of its gene is Val16Ala. OBJECTIVE: The aim was to investigate a possible mutation in pregnant women who had abortion during the first trimester of pregnancy due to blighted ovum...

INTRODUCTION: Hydatidiform moles (HM), presenting as complete (CHM) and partial (PHM) form, are rare pregnancy disorder. Diagnosis is based on clinical presentation, ultrasound imaging findings and pathological examination of products of conception. Protein p57, encoded by CKDN1C gene, is paternally imprinted and maternally expressed gene and provides quick insight in genetic basis of HM and allows distinction of CHM from all other conceptions. compare the preevacuational and pathohistological diagnosis with outcome of p57 immunostaining...

The role of the complement system in first-time pathologic first-trimester miscarriage was investigated. In this case-control study, tissue samples of 126 women with pathologic miscarriage and termination of normal pregnancies were assessed. The pathologic pregnancy group consisted of 40 women with missed miscarriage, 13 women with incomplete miscarriage and 10 women with a blighted ovum. The control group consisted of 63 normal-appearing pregnancies. Immunoreactivity for C4d, Bb and MBL was evaluated in the deciduas and villous trophoblasts separately using a semi-quantitative histological scoring system (H-score)...

BACKGROUND: Chromosomal disorders are the most common cause of first trimester spontaneous abortion. Among the human chromosomes, chromosome no.9 was the most common structural chromosomal variant and it is not thought to be of any functional importance, which often considers as a normal variation in structural polymorphisms, nevertheless there are some studies which claim that there is an association between heteromorphism of chromosome no.9 and some pregnancy complication. CASE: To postulate any correlation between chromosome no...

BACKGROUND AND OBJECTIVE: Miscarriage is a common complication of early pregnancy with medical and psychological consequences. Dilation and Curettage are considered as two standard caring ways for early pregnancy failure. Alternatively misoprostol has been used as a single agent for termination of early pregnancy. Aim of the present study was to compare the usefulness of serum β-hCG measurement and ultrasound examination to predict complete abortion after medical induction. METHODS: There were one hundred and thirty three patients experiencing missed abortion or blighted ovum...
