The use of computed tomography (CT) in 28 patients with surgically proved prolactinomas is described. The authors' experience suggests that in evaluating patients with galactorrhea-amenorrhea syndrome, CT in combination with pluridirectional tomography usually provides sufficient information to make further invasive studies unnecessary. In selected cases with low-density areas within the sella as seen on CT, pneumoencephalography is still advisable to distinguish between the empty sella and the necrotic tumor. Angiography is still necessary to exclude vascular causes for suprasellar and parasellar masses such as aneurysms and meningiomas.

Background: Endoscopic ultrasound-guided transmural drainage (EUS-TD) is widely performed to treat postoperative peripancreatic fluid collection (POPFC). Recent reports on EUS-TD lack a consensus on stent selection. This study aimed to assess the efficacy of EUS-TD for POPFC using an external drainage-based approach.

It is classified into six types: severe perinatal, benign prenatal, infantile, pediatric, adult, and odonto. HPP with femoral hypoplasia on fetal ultrasonography, seizures, or early loss of primary teeth can be easily diagnosed.

Background: The early mortality of trauma patients, mainly from hemorrhagic shock, raises interest in detecting the presence of non-exteriorized bleeding. Intra-hospital EFAST (Extended Focused Assessment with Sonography for Trauma) has demonstrated its utility in the assessment and management of severe trauma patients (STP). However, there is a lack of data regarding the diagnostic performance of prehospital EFAST (pEFAST).
