Ultrasound is now an established tool in the clinical management of pregnancy. Consequent to its major role in clinical decision-making and its remarkable operator dependence, it is necessary to have guidelines for minimum standards of performance of this modality in each area of obstetric ultrasound. The Society of Fetal Medicine guidelines have been developed for use by all the practitioners performing antenatal ultrasound scans. They are intended to provide the entire medical community with standards for the performance of quality ultrasound examinations. Practitioners are encouraged to go beyond these standards in relevant clinical situations. Each guideline in this document has undergone extensive discussion followed by a consensus. In a rapidly evolving technological and research environment, it is imperative to constantly re-evaluate and update these guidelines. Practitioners are advised to be aware of these updates and incorporate these into their daily practice.
Zika virus (ZIKV) belongs to the family of flaviviruses and is transmitted by mosquitoes of the genus Aedes (A. aegypti and A. albopictus). ZIKV infection in pregnancy can have serious implications on the fetus and the neonate. Vertical transmission to the fetus can occur irrespective of symptomatic or asymptomatic infection in the pregnant woman and the risk can persist throughout pregnancy. The exact frequency of maternal-to-fetal transmission of Zika virus is difficult to determine accurately. The greatest risk of serious fetal sequelae is seen if the infection occurs within the first and second trimester. However, they can also be seen with infections in the third trimester. This document describes the presentation, fetomaternal manifestations, role of prenatal Ultrasound in diagnosis of infection, testing methods and the management in pregnancy and screening in the neonatal period. In the absence of robust evidence as to the definite effects, this document is aimed at providing practice recommendations for the management of this infection.
Posterior fossa lesions are rare. Introduction of high resolution ultrasound with 3D reconstruction and endovaginal evaluation of fetal brain through the fontanelle helps in better understanding of neuroanatomy. MRI is often used as an additional tool for evaluation in addition to ultrasound studies. Major components of posterior fossa such as cerebellar hemispheres, vermis, fourth ventricle, cisterna magna, and their normal variants and abnormalities can be demystified by ultrasound studies. Morphometry of these structures helps in the diagnoses of these abnormalities.
Few adult haemangiomas of larynx have been reported. Most common presentations are in infants where the incidence is about 4% -5% [1]. In children they resolve by age of five whereas in adults they do not regress. In children the most common modality of treatment is by propranolol. In adults, there are various modalities of surgical excision by laser excision with Co 2 or KTP and electrocautery assisted excision. We are presenting a case of adult laryngeal haemangioma that presented with blood-tinged sputum on coughing since 8 months and we managed with micro laryngeal surgical excision by coblation without any complications.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
