Objective: the aim of our study was to assess the contribution of quantitative fluorescent polymerase chain reaction (QF-PCR) and pathology studies in the diagnosis of diandric triploidies/partial hydatidiform moles. Methods: this study included all fet al triploidies diagnosed by QF-PCR in chorionic villi or amniotic fluid in the 2 centers of BCNatal in which a maternal saliva sample was used to establish its parental origin. Pathology studies were performed in products of conception and concordance between a partial hydatidiform mole diagnosis and the finding of a diandric triploidy was assessed. Results: among 46 fetal triploidies, found in 13 ongoing pregnancies and in 33 miscarriages, there were 26 (56%) diandric triploidies. Concordant molecular (diandric triploidy) and pathology results (partial mole) were achieved in 14 cases (54%), while in 6 cases (23%) pathology studies were normal, and in the remaining 6 cases (23%) pathology studies could not be performed because miscarriage was managed medically. Conclusions: diandric triploidy is associated with partial hydatidiform mole and its diagnosis is crucial to prevent the development of persistent trophoblastic disease. QF-PCR analysis in chorionic villi or amniotic fluid provides a more accurate diagnosis of the parental origin of triploidy than the classical pathology studies.

Partial Mole

Partial hydatidiform mole can evolve into a metastatic trophoblastic tumor. A 36-year-old, multiparous woman, pregnant with a 22-week embryonic hydatidiform mole, having spontaneously expelled. Histopathological examination showed a non-invasive partial mole. During biological monitoring, a trophoblastic tumor was diagnosed with pulmonary metastasis on CT-scan and myometrial invasion by MRI. Authors opted for a monochemotherapy with a good evolution. The potential risk of malignant transformation of the partial hydatidiform mole requires an adequate therapeutic strategy with strict monitoring.

Rule Out

ABSTRACT Partial hydatidiform mole (PHM) with a singleton live fetus is a rare condition. A live baby of 2000 grams with many external congenital anomalies like hydrocephalus, bilateral congenital talipus equino varus (CTEV), meningomyelocele and spina bifida was delivered. Placenta weighed 700 grams and PHM was confirmed by histopathological examination. Baby expired one hour after birth. Baby was sent for autopsy which documented various anomalies. Partial hydatidiform mole is a histopathological entity characterized by focal trophoblastic hyperplasia with villous hydrops together with identifiable fetal tissue. PHM with a single live fetus is a rare condition which is reported by very few authors. Not all the cases of partial mole can be detected by USG/Doppler. If any anomalies are detected, PHM should be thought among the conditions possible. MShCG and karyotyping can be done to rule out this condition. Placenta has to be sent for histopathological examination to confirm the diagnosis of PHM. These patients are prone to go in preterm labor and preterm premature rupture of membranes (PPROM). There is possibility of malpresentations like transverse lie among these cases.

Abstract Purpose To establish the distribution of diandric and digynic triploidy depending on gestational age. Methods 107 triploid samples tested prospectively in a single genetic department during a four-year period were analyzed for parental origin of triploidy by Quantitative Fluorescent Polymerase Chain Reaction (QF-PCR) (n=95) with the use of matching parental samples or by MS-MLPA (n=12), when parental samples were unavailable. Tested pregnancies were divided into three subgroups with regard to the gestational age at spontaneous pregnancy loss: <11 gestational weeks, 11–14 gestational weeks, and >14 gestational weeks. Results Diandric triploidy constituted overall 44.9% (46.5% in samples miscarried <11 gestational weeks, 64.3% in samples miscarried between 11 and 14 gestational weeks, and 27.8% in pregnancies which survived >14 gestational weeks). Conclusions The distribution of diandric and digynic triploidy depends on gestational age. The majority of diandric triploid pregnancies is lost in the first trimester of pregnancy. In the second trimester, diandric cases are at least twice less frequent than digynic ones.

Objective: To study the spectrum of histopathological diagnosis of endometrial lesions and their distribution according to age. Methods: All the endometrium samples obtained by the procedure of dilatation and curettage and hysterectomy sent for histopathological examination at Pathology Department of Gandaki Medical College Teaching Hospital, Pokhara, Nepal. The study duration was total 12 months ranging from July 2016 to June 2017. All the endometrial samples were processed, sectioned at 4 - 6 μm and stained with routine H & E stain. Patient’s data including age, sex, procedure of the biopsy taken and histopathological diagnosis were noted. A pathologist, using Olympus microscope, reported the slides. Cases were reviewed by a second pathologist whenever necessary. Results: A total of 128 cases were studied. The most common histopathological diagnosis was proliferative endometrium (28.9%) followed by disorder proliferative endometrium (15.65%). Most of the patients were in age group 36 - 45 years comprising 32.03%. Hydatidiform mole comprised of 7.03% and among Hydatidiform mole, partial mole was more common. Dilatation and curettage (82.8%) was the common procedure in compare to hysterectomy for the evaluation of endometrial lesions. Conclusions: In this study, we observed a variety of endometrial lesions. Most of them are benign; among benign, proliferative endometrium was the common histopathological diagnosis followed by disorder proliferative endometrium. Most common presenting age group was found to be at 36 - 45 years. In evaluation of hydatidiform mole, partial mole was more frequent in compare to complete mole. Conventional dilatation and curettage is the preferred method in developing countries with limited resource to screen endometrial lesion and therefore biopsy should be sent for histopathological examination. Thus histopathological examination of routinely stained hematoxylin and eosin is readily available and widely accepted standard technique for evaluation of the endometrial lesions.

The sterile-womb dogma in uncomplicated pregnancy has been lively debated. Data regarding the in utero microbiome environment are based mainly on studies performed at the time of delivery. Aim: To determine whether human placenta and amniotic fluid are populated by a bacterial microbiota in the first and second trimesters of pregnancy. Materials & methods: We analyzed by next-generation sequencing method 24 and 29 samples from chorionic villus sampling (CVS) and amniocentesis (AC), respectively. The V3 region of the 16S rRNA gene was sequenced. Results: 37.5% of CVS and 14% of AC samples showed the presence of bacterial DNA. Conclusion: Our study suggests that bacterial DNA can be identified in the placenta and amniotic fluid during early prenatal life.

Invasive Mole

Invasive mole is a condition where a molar pregnancy, such as a partial hydatidiform mole or complete hydatidiform mole, invades the wall of the uterus, potentially spreading and metastasizing to other parts of the body. Here is a case who presented with history of evacuation for molar pregnancy. She presented with irregular P/V bleeding on and off and after admission silent perforation with massive haemoperitoneum was detected for which emergency laparotomy was done. She recovered and was followed up till her b-hCG levels were within normal limits. As patient presented to us with haemoperitoneum and on laparotomy, there was invasion into whole of the uterus, it could not be saved and hysterectomy was done.Faridpur Med. Coll. J.
