Evaluation of serum paraoxonase, 1 and its association with serum cholinesterase as a cause of congenital anomalies

Background: Birth defects are conditions of prenatal origin that are present at birth, potentially impacting an infant's health, development, and/or survival. Several environmental toxins affect the growth of the fetus during the intrauterine period by affecting various cellular components. Pesticides and industrial chemicals are known toxins that can hinder the developmental process. In this study, authors are evaluating the relation of cholinesterase and paraoxonase-1 with visible congenital anomalies.Methods: Sixty babies delivered in the labor room were selected for the study. They were divided into two groups. Thirty newborns with visible congenital anomalies were included in Group I. Only babies with visible congenital anomalies were taken as inclusion criteria for this group. This group was compared with Group II, which were taken as controls and consisted of 30 healthy newborns without any congenital anomalies. Serum cholinesterase and serum paraoxonase-1 were estimated and statistical tests were applied.Results: Serum cholinesterase and serum paraoxonase-1 were significantly low in the babies with visible congenital anomalies. Serum cholinesterase levels showed a statistically significant positive correlation with serum paraoxonase 1 level in both the groups.Conclusions: Decrease in acetylcholinesterase by various environmental toxins and the associated decrease in serum paraoxonase level imposes significant oxidant stress and the resultant risk of developing congenital anomalies.

Endometrial stromal nodule: a rare case report

Endometrial stromal nodules (ESN) are benign tumours of mesenchymal origin with features reminiscent of proliferative phase endometrial stroma. Diagnosis of ESNs can be established only by light microscopy and no preoperative diagnostic methods are available. Although ESNs are benign and rare, distinguishing it from other types of invasive stromal tumours is of utmost importance since prognosis and management change considerably with the diagnosis. This was a rare case report of endometrial stromal nodule in a nulliparous woman, 30 years old who presented with complaint of menorrhagia and primary infertility and had a preoperative diagnosis of large leiomyoma with cystic degeneration. She underwent a fertility preserving conservative surgery i.e. myomectomy via abdominal route, histopathology reports of which revealed endometrial stromal nodule that changed the final diagnosis and follow up regime of the patient.
