PET/CT Imaging in Treatment Planning and Surveillance of Sinonasal Neoplasms.

Sinonasal cancers are uncommon malignancies with a generally unfavorable prognosis, often presenting at an advanced stage. Their high rate of recurrence supports close imaging surveillance and the utilization of functional imaging techniques. Whole-body F-FDG PET/CT has very high sensitivity for the diagnosis of sinonasal malignancies and can also be used as a "metabolic biopsy" in the characterization of some of the more common subgroups of these tumors, though due to overlap in uptake, histological confirmation is still needed.

Significance of detectable hepatitis B virus DNA in liver allograft tissue in long-term follow-up of liver transplant recipients.

Background And Aim: The objective of this study was to evaluate the long-term presence of hepatitis B virus (HBV) DNA in the liver grafts of liver transplant patients who received hepatitis B immunoglobulin (HBIg) plus oral antiviral hepatitis B virus prophylaxis and had negative HBV serum markers.

Materials And Methods: Patients aged 18 years or older who underwent liver transplantation for HBV-related liver disease, had negative serum viral markers, and had a liver biopsy at least 3 years after liver transplantation were eligible for this study. Clinical, serological, and pathological data were retrospectively obtained from medical records.

Objective: The objective of the study was to examine a possible relationship between morphometric corpus callosum (CC) measurements, age, and gender characteristics using MR images.

Materials And Methods: The medical data and MR examinations of 436 consecutive subjects were retrospectively reviewed. The CC thickness from five different sites, and additionally splenium length, height, and total length of the CC, and the splenium index (SI) were measured with a mid-sagittal T1-weighted sequence.

Is visceral obesity associated with colorectal cancer? The first volumetric study using all CT slices.

Purpose: We aimed to examine the possible relationship between abdominal adiposity parameters and the presence of colorectal cancer (CRC) and between these adiposity parameters and various histopathologic findings of the tumor.

Methods: A total of 60 control subjects and 111 CRC patients, 63 with early-stage and 48 with advanced-stage disease, were enrolled. Medical data and abdominopelvic computed tomography (CT) examinations of each study group were retrospectively reviewed.

Effect of gadolinium concentration on temperature change under magnetic field.

Gadolinium based contrast agents (GBCAs) were found to play a role in nephrogenic systemic fibrosis in patients with and without renal impairment. Therefore, preserving the structural stability of GBCAs to reduce their propensity to liberate Gd3+ is of utmost importance. This study evaluates the effect of gadolinium concentration of GBCAs on solution temperature under magnetic fields.

Fecal Elastase Levels Predict Honeycombing in Pancreas Detected with Endoscopic Ultrasound.

Background And Study Aims: We aimed to demonstrate the association between fecal elastase levels and Rosemont categories in patients with chronic changes in pancreas detected with endoscopic ultrasound.

Patients And Methods: Patients were selected consecutively from endosonography examinations performed for upper gastrointestinal subepithelial lesions and for pancreas evaluation. Pancreas imaging findings were categorized according to the Rosemont criteria using echoendoscope.

Distribution characteristics of combat-related shrapnel and relationship to weapon type and conflict location: Experience of an operational field hospital.

Background: The aim of this study was to investigate the characteristics of shrapnel distribution in the body and a possible relationship to the type of weapon and type of location of the conflict.

Methods: The records of 246 patients admitted to a level-III trauma center with any kind of firearm injury were examined retrospectively. Ninety patients who had at least 1 radiologically-proven piece of shrapnel in their body were included in the study.

Analyses of combat-related injuries to the maxillofacial and cervical regions and experiences in an operational field hospital.

Background: With the changing conditions of war, maxillofacial injuries are observed more frequently. Particularly in urban areas, high-energy explosive devices (HEEDs), such as improvised explosive devices, are often used alongside long-barreled weapons (LBWs). It is important to use trauma scoring systems and a multidisciplinary approach for medically and accurately responding to the trauma patient in a timely manner.

Case Report: Ultrasound-Guided Infraclavicular Brachial Plexus Block for a Case with Posterior Elbow Dislocation.

Background: The interest in regional anesthesia procedures for the management of upper-extremity emergencies has increased. Toward that end, supraclavicular, interscalene, or infraclavicular approaches, with or without ultrasound guidance, are used for brachial plexus nerve blocks. Although many studies have reported on the use of ultrasound-guided supraclavicular and interscalene brachial plexus blocks for upper-extremity dislocations, very few studies have reported on the use of ultrasound-guided infraclavicular brachial plexus blocks.

Improving the standard sequential treatment of Helicobacter pylori with either extended treatment or by adding bismuth.

Background And Study Aims: Standard sequential treatment for Helicobacter pylori (H. pylori) eradication has less success because of increasing clarithromycin resistance. Extended treatment and bismuth containing regimens were, therefore, investigated.

Efficiency of instant messaging applications in coordination of emergency calls for combat injuries: A pilot study.

Background: Coordination of an emergency response team is an important determinant of prompt treatment for combat injuries in hospitals. The authors hypothesized that instant messaging applications for smartphones could be appropriate tools for notifying emergency response team members. The objective of this study was to investigate the efficiency of a commercial instant messaging application (WhatsApp, Mountain View, CA) as a communication tool for the emergency team in a level-I trauma center.

Ultrasound-Guided Femoral Nerve Blockage in A Patellar Dislocation: An Effective Technique for Emergency Physicians.

Background: Patellar dislocation is an orthopedic emergency and its reduction can be painful. The aim of this case is to show that the ultrasound-guided femoral nerve blockage can be effectively used in the pain management of patellar reduction in the emergency department (ED).

Case Report: A 21-year-old man was admitted to our ED after suffering a fall down a flight of stairs.

Apparent diffusion coefficient value in invasive ductal carcinoma at 3.0 Tesla: is it correlated with prognostic factors?

Objective: To investigate the correlation between apparent diffusion coefficient (ADC) values and prognostic factors in patients with invasive ductal carcinoma (IDC).

Methods: 48 lesions belonging to 47 patients with histopathologically proven IDC were examined using conventional MR and diffusion-weighted imaging at a 3.0-T system.

Surgically Confirmed Intra- and Extratesticular Hematoma Clinically Mimicing Epididymo-Orchitis and Radiologically Mimicing Traumatic Torsion.

Background: Scrotal blunt trauma may result in injuries, such as testicular rupture, dislocation, torsion, hematoma, spermatic cord injury or contusion, and epididymal, scrotal, and urethral injuries. Ultrasonography (US) has a crucial role in the evaluation of those kinds of pathologies. Early diagnosis of testicular rupture may lead to the salvaging of the testicle by prompt surgical exploration within 72 h.

Complete currarino syndrome recognized in adulthood.

Currarino syndrome is a hereditary pathology that is characterized by sacrococcygeal bone defect, presacral mass, and anorectal malformation. Sacrococcygeal bone defect is almost always a part of the syndrome. The complete form of this entity displays all three abnormalities and is very uncommon.

Bilateral Bochdalek hernias associated with severe aortic tortuosity and aberrant right subclavian artery.

Although Bochdalek hernia is the most common congenital diaphragmatic hernia in adults, bilateral occurrence is rare. To the best of our knowledge, only case reports on Bochdalek hernia and its associated pathologies have been previously published. Herein, we present the case of a 27-year-old man with bilateral Bochdalek hernias, which were detected incidentally.
