Clinical Results of Percutaneous Transhepatic Biliary Drainage With Different Hepatic Access and Methods in the Treatment of Obstructive Jaundice.

Background: Percutaneous transhepatic biliary drainage (PTBD) is a common procedure for biliary obstruction jaundice caused by biliary tract obstruction. PTBD can be performed using external or external-internal methods, by the right or left lobe approach. However, differences in both the method used and the hepatic approach may affect success rates and complications.

Changes of the Buccal Fat Pad Volume According to the Different Age Groups, Gender, and Body Mass Index: An Evaluation With Computed Tomography.

Objectives: We investigated volumetric changes in buccal fat pad (BFP) in age groups and sexes by cranial or neck computed tomography (CT) or cranial CT angiography.

Methods: One hundred twenty patients underwent cranial or neck CT examinations or cranial CT angiography were retrospectively screened: 18-29 years old (group 1), 30-49 years old (group 2), and 50 years and older (group 3). Left buccal fat tissue measurements were performed in age groups, sexes, and body mass index (BMI) groups.

Evaluation of peripheral and central olfactory pathways in HIV-infected patients by MRI.

Aim: To investigate peripheral and central olfactory pathways using cranial magnetic resonance imaging (MRI) in human immunodeficiency virus (HIV)-infected patients.

Materials And Methods: The cranial MRI images of 37 HIV-infected adult patients and 37 adults without HIV infection having normal cranial MRI results were included in the study. In both groups, olfactory bulb (OB) volume and olfactory sulcus (OS) depth; and insular gyrus and corpus amygdala areas were measured using cranial MRI.

Evaluation of the relationship between trochlear and patellar morphology and patellar chondromalacia with magnetic resonance imaging.

It was aimed to investigate the relationship between magnetic resonance imaging (MRI) measurements of trochlear and patellar morphology and grade 3-4 patellar chondromalacia. Grade 3-4 patellar chondromalacia group, and an age- and sex-matched control group with normal patellar joint cartilage were comprised. For trochlear morphology evaluation in MRI; sulcus angle, trochlear angle, lateral trochlear inclination angle and medial trochlear inclination angle were measured.

Attention-based rehearsal: Eye movements reveal how visuospatial information is maintained in working memory.

The human eye scans visual information through scan paths, series of fixations. Analogous to these scan paths during the process of actual "seeing," we investigated whether similar scan paths are also observed while subjects are "rehearsing" stimuli in visuospatial working memory. Participants performed a continuous recall task in which they rehearsed the precise location and color of three serially presented discs during a retention interval, and later reproduced either the precise location or the color of a single probed item.
