Prediction of Neonatal Outcome by Umbilical Artery Velocimetry in Intrauterine Growth Restriction: A Study in Western Nepal

Abstract The introduction of Doppler velocimetry to obstetrics offered a noninvasive and safe imaging modality of indirectly assessing the fetal and uteroplacental circulation. Obstetric Doppler ultrasound plays an important role in detecting Intra Uterine Growth Restriction (IUGR). The early diagnosis of IUGR with the help of abnormal flow patterns in umbilical, uterine and middle cerebral arteries using Doppler ultrasound may help in reducing perinatal and neonatal mortality and morbidity as well as reducing perinatal complications. This provides for timely interventions to prevent progression from IUGR to Intrauterine death (IUD).The study was carried out in 140 patients in Manipal Teaching Hospital, Pokhara for a period of twenty months from October 2013 to June 2015. All the cases presented to Radiology department for obstetric Doppler with clinical suspicion of IUGR were taken up for the study and obstetric doppler of umbilical artery was performed. Seventy two out of 140 (51.50%) had abnormal umbilical artery Doppler velocimetry. Fifty seven out of these 72 subjects (positive predictive value -79.2%) with abnormal umbilical artery Doppler were later born with small for gestational age (SGA). The S/D ratio of umbilical artery of 3 or greater was considered abnormal in predicting IUGR and it showed sensitivity, specificity, positive predictive value, and negative predictive value of 76%, 76.9%, 79.2% and 73.5% respectively. Admission to the Neonatal Intensive Care Unit (NICU) and incidence of perinatal and neonatal mortality increased with the worsening of Doppler velocimetry. Twenty seven out of one hundred and forty neonates developed perinatal asphyxia, out of which 26 (96.3%) had abnormal umbilical artery velocimetry. NICU admissions comprised of a total of 30 neonates, out of which 27(90%) had abnormal umbilical artery Doppler velocimetry prenatally. Fifteen out of thirty didn't survive, all of whom had abnormal umbilical artery Doppler velocimetry prenatally. There were 3 still born and all of them had abnormal umbilical artery velocimetry prenatally. The study could underline that abnormal Doppler velocimetry has a fairly good sensitivity and specificity for predicting IUGR and it is related with poor neonatal outcomes

Hydatidosis of infratemporal fossa with proptosis – an unusual presentation: a case report and review of the literature

Abstract Background Hydatid disease is one of the common zoonotic diseases caused by the larval stage of Echinococcus granulosus. It is endemic in sheep-raising and cattle-raising areas worldwide and humans are an accidental intermediate host following the ingestion of the larvae. Head and neck involvement of echinococcosis is a rare entity and involvement of the infratemporal region is extremely rare even in endemic areas. Only a few cases of hydatid cysts located in the infratemporal fossa have been reported in the literature. Moreover, extension of the hydatid cyst into the intraorbital region and infiltrating into the surrounding orbital bone is even rarer. Case presentation We present a case of a 65-year-old Gurung Nepalese woman with painless proptosis of her left eyeball of 2 months’ duration with recent progressive diminution of vision for 15 days. Radiological findings showed a cystic mass in the left infratemporal fossa extending into the left orbit and involving the surrounding orbital bone. Surgical removal was carried out. On histopathological evaluation, it was reported as hydatid cyst infiltrating into the bone. She was prescribed albendazole and discharged after surgery. However, she was lost to follow up and returned after 15 months with recurrence and proptosis of the same eye. Repeat excision of the lesion was carried out and postoperatively she was administered tablet albendazole. She was found to be disease free after 6 months of follow up. Conclusions Clinical and radiological findings are important but may not be sufficient in the preoperative diagnosis of hydatid disease especially if rare sites are involved. Proptosis may be seen in several conditions and orbital or infratemporal hydatidosis, although rare, should be considered a differential diagnosis
