Introduction There are three groups of disorders during pregnancy: disorders specific for pregnancy that resolve spontaneously or soon after delivery, acute hepatic disorders coinciding with pregnancy, and chronic disorders. Drug-induced liver disease prevails among women and it is estimated to be a leading cause of acute liver injury. Drug-induced hepatitis is rare in pregnancy with only a few cases reported in literature. Alpha-methyldopa is one of the commonly used drugs in pregnancy that could cause hepato-toxicity with different clinical presentations and possible adverse effects on normal course of pregnancy. Case outline We reported a rare case of hepatotoxicity caused by alpha-methyldopa in 26 gestational weeks pregnancy in a 35-year-old patient admitted because of jaundice and elevated liver function tests. She had been using antihypertensive drug, alpha-methyldopa, from 12th gestational week, and no other medication or supplementation was recorded. Ultrasound of the abdomen excluded obstruction or any other abnormalities. Autoimmune panel was done. Biochemical analyses were indicative of toxic acute liver injury caused by alpha-methyldopa according to values of transaminase. After 13 days, patient was discharged recovered from the hospital. Conclusion Diagnosis of alpha-methyldopa hepatotoxicity is challenging since the low incidence, un-predictability, diverse symptomatology and absence of specific biomarkers. That is why timely diagnosis is crucial for the well-being of both future mother and child. © 2024, Serbia Medical Society. All rights reserved.

Introduction Progress of labor in multiparous women usually is not accompanied with risk of any kind of birth trauma. Case Outline We report a very rare case of rib fracture in a neonate during vaginal delivery in the 39/40 week of gestation. The expulsion started spontaneously without any manipulation from the obstetrician. Live male newborn was delivered 4650 g. in weight, 55 cm long, with head circumference of 39 cm, Apgar score 9. The child was immediately examined by the neonatologist. Crepitations were palpable over the left hemithorax, and auscultatory on the left side inspiratory cracks. Finding was suspicious for rib fracture on the left side posteriorly and brachial plexus palsy, while other findings were normal. X-ray finding was inconclusive, but suspicious for fracture of the 4th, 5th, and 6th left rib posteriorly, without dislocation of bone fragments. There were no signs of pneumothorax. Dorsal position of the newborn was considered sufficient, accompanied with analgetics. X-ray was scheduled in a week because formation of the calus would be the only objective sign of previous rib fracture. On the control X-ray fracture lines were clearly visible on the 3rd, 4th, 5th, 6th and 7th rib posteriorly, without dislocation of bone fragments with initial calus formation. The child was discharged from hospital in good condition after two weeks, for further outpatient care. Conclusion With timely diagnostics of this very rare intrapartal fracture, adequate treatment, dorsal position and close control of clinical condition of the newborn, serious and potentially life threatening complications can be avoided.

Antibodies to phospholipids (aPL) have been shown to adversely affect trophoblast invasion in vivo and in vitro. HTR-8/SVneo cells derived from first trimester of pregnancy extravillous trophoblast were studied. Matrigel invasion assay, cytochemistry and cell-based enzyme-linked immunosorbant assay (ELISA) with aPL or normal IgG was used. Our data show that aPL at 100 μg/ml decrease invasiveness of HTR-8/SVneo cells to 60% of control (p<0.01), and this was also shown for primary cytotrophoblast (to 15.5% of control, p<0.001). aPL treatment caused a significant decrease in integrin α1, α5, and β1 proteins (86%, 84%, and 87%, respectively). We conclude that HTR-8/SVneo cell culture is a suitable model to study mechanisms of action of aPL on trophoblast, which in HTR-8/SVneo cells inhibit invasion by decreasing integrins α5, α1, and β1. © 2008 Elsevier GmbH.

Introduction/Objective Increased incidence of cesarean sections leads to the reduction of incidence of instrumental vaginal deliveries. The aim of this study was to analyze the trends of forceps deliveries at the tertiary healthcare facility. Methods The study was performed at the Clinic of Gynecology and Obstetrics, covering a 30-year period, from 1987 to 2016 with a total of 198,882 births. Results Forceps delivery rate was significantly lowering during time, while the cesarean section rates were rising. Conclusion Using linear, cubic and quadratic prediction models, we can estimate that in the year 2020 there will be no more forceps deliveries. However, minding the confidence interval of 95% some forceps deliveries might still be carried out. Since it has been shown that the forceps is a very useful obstetric tool, this very important skill might soon be neglected due to the lack of training. © 2019 Serbia Medical Society.

Antiphospholipid syndrome (APS) is a complex thrombo-inflammatory autoimmune disease characterized by the presence of antiphospholipid antibodies (aPL). Women with APS are at high risk of recurrent early pregnancy loss as well as late obstetrical complications—premature birth due to placental insufficiency or severe preeclampsia. Accumulating evidence implies that vascular thrombosis is not the only pathogenic mechanism in obstetric APS, and that the direct negative effect of aPL on the placental cells, trophoblast, plays a major role. In this review, we summarize the current findings regarding the potential mechanisms involved in aPL-induced trophoblast dysfunction. Introduction on the APS and aPL is followed by an overview of the effects of aPL on trophoblast—survival, cell function and aPL internalization. Finally, the implication of several non-coding RNAs in pathogenesis of obstetric APS is discussed, with special emphasis of their possible role in trophoblast dysfunction and the associated mechanisms. © 2023 by the authors.
