Objective The study aimed to utilize the neurosonographic findings in neonates in early diagnosis, prediction of their long-term outcome, parental counseling, and early intervention. Methods The study was carried out in neonatal intensive care unit (NICU) of Shri BM Patil Medical College and Hospital. All preterms and term babies with neurological clinical findings were included in the study. Neurosonogram was done within first 7 days in preterms and when indicated in terms. Philips HD11XE ultrasound and color Doppler unit were used with a small footprint probe. Color Doppler images for vessels were performed for screening of vascular changes. Results A total of 215 babies were included, of which 80 (32%) were term and the rest were preterm. Mean weight of term babies was 2.8 kg and that of preterm was 1.2 kg.Among term babies, 78% showed ultrasound abnormality, and among preterm, 42%showed abnormalities. Among term babies, 60% and, among preterms, 30% had birth asphyxia. Periventricular leukomalacia was the most common and earliest finding followed by thalamic hyperechogenicity and intracranial hemorrhage. Intraventricular hemorrhage was more common in preterm babies. Other common finding in NICU was meningitis which was more common in pretrms. Among congenital anomalies, corpus callosal agenesis was more common. Conclusions Point of care ultrasonography along with Doppler study is very useful and safe to use in NICUs. It helps in diagnosis, patient management as well as prediction of many short- and long-term outcomes.

Introduction: Cervical region is the commonest area of lymphadenopathy which is easily accessible to ultrasound and Doppler study. The morphological and vascular-architectural differences among various nodal diseases aids in differentiating benign from malignant causes. Methods: The study was done on the 108 patients referred to Department of Radiology andImaging, TUTH for ultrasound of cervical lymphadenopathy who subsequently underwentFNAC examination. Gray scale evaluation for morphology of the nodes along with Doppler evaluation for resistive index (RI), pulsatility index (PI) and Peak systolic velocity (PSV) were done and correlated with FNAC findings. Results: Among the 108 lymph nodes, 24 were proven to be malignant on FNAC. Features such as S/L ratio >0.5, absence of echogenic hilum, and abnormal vascular pattern demonstrated sensitivities of 96%, 92%, and 87%, specificities of 74%, 65% and 77% and positive predictive values (PPVs) of 51%, 43%, and 55% respectively. The cutoff values for RI, PI and PSV were found to be 0.705, 1.34 and 17.5 cm/s with sensitivities of 96%, 96% and 87%, specificities of 95%, 99% and 88% and positive predictive values (PPVs) of 85%, 95% and 70% respectively. Conclusion: Ultrasound findings of S/L ratio, absence of echogenic hilum, abnormal vascular pattern and Doppler indices revealed good sensitivity, specificity, and accuracy in differentiating benign and malignant lymph nodes.

Background: Pre-eclampsia affects 2-5% of pregnancies and is a major cause of perinatal and maternal morbidity and mortality. Doppler is a non-invasive method for evaluation of feto-placental circulation without affecting pregnancy. A high resistance index in uterine artery Doppler waveform has been shown to be the best non-invasive screening test. Thus, we have conducted this study to find out the predictive value of transvaginal uterine artery doppler in early pregnancy for the prediction of pre-eclampsia. The aim of the study was early prediction of pre-eclampsia by trans-vaginal uterine artery Doppler study at 12-16 weeks.Methods: According to the study criteria 100 antenatal women between 12 to 16 weeks of singleton pregnancy attending out patient in the Department of OBG of S. D. M. Medical College Dharwad were included. After an informed consent, the women underwent ultrasound for dating and subsequently trans-vaginal ultrasound along with color doppler was performed to obtain uterine artery indices. These women were again rescanned at 24-26 weeks of gestation trans-abdominally and further followed up clinically for development of preeclampsia.Results: Out of 100 women, 22 patients developed preeclampsia. At 12-16 weeks 35% of women had bilateral uterine artery notching, mean RI was 0.57 and PI was 0.89. When uterine artery notch at 12-16 weeks alone was considered, 34.28% of women developed preeclampsia. Detection rate increased to 85.71% when RI>0.65 was also included along with notching. Uterine artery notching at 12-16 weeks gestation had 34.29% sensitivity, 84.62% specificity, 70.51% NPV. When notch and RI>0.65 considered together sensitivity and NPV increases to 85.71% to 98.25%.Conclusions: The uterine artery Doppler waveform indices at 12-16 weeks are the best non-invasive screening test available for early prediction of preeclampsia.
