Autoimmune Pancreatitis Type 1 with Biliary, Nasal, Testicular, and Pulmonary Involvement: A Case Report and a Systematic Review.

Introduction: Immunoglobulin G4-related disease (IgG4-RD) is an immune-mediated condition associated with fibroinflammatory lesions that can occur at almost any anatomical site. It often presents as a multiorgan disease that may mimic malignancy, infection, or other immune-mediated conditions. Autoimmune pancreatitis (AIP) type 1 is the most prominent manifestation of IgG4-RD in the digestive tract, with common extra-pancreatic inflammation.

Hormone replacement therapy-related changes in the early postmenopausal period (critical window): an in vivo brain proton magnetic resonance spectroscopy study.

Aim: Findings from clinical studies in postmenopausal women with late initiation of hormone replacement therapy (HRT) that test whether HRT protects cognitive functions in women are inconsistent. The aim of this study was to investigate the effects of HRT on brain metabolite ratios when initiated in the early postmenopausal period (critical window).

Materials And Methods: Proton magnetic resonance spectrometry (1H MRS) was performed in 4 brain regions of 47 healthy postmenopausal women (21 received HRT, 26 did not).

The significance of magnetic resonance imaging and computed tomography findings in sphenoid sinus agenesis.

Agenesis of the sphenoid sinuses is a very rarely encountered anatomic variation. Findings on magnetic resonance imaging can mislead the radiologist and clinician. Therefore, the gold standard for diagnosis is computed tomography (CT) of the paranasal sinuses.

Importance of the ultrasonography in diagnosis of ileal duplication cyst.

Gastrointestinal duplication cysts are rare congenital anomalies that can be seen in anywhere of the gastrointestinal system from the mouth to the anus. These are prenatally diagnosed through antenatal ultrasonography. However, attention must be paid since these formations might be confused with ovarian or mesenteric cysts.

The benefit of expiratory-phase quantitative CT densitometry in the early diagnosis of chronic obstructive pulmonary disease.

Purpose: We aimed to compare the inspiratory and expiratory quantitative computed tomography (CT) densitometric data of healthy volunteers, individuals with chronic obstructive pulmonary disease (COPD) risk, and COPD patients to aid in the early diagnosis of COPD.

Materials And Methods: Of the study patients, 14 were healthy volunteers (Group I), 12 were patients at risk for COPD (Group II), and 13 were COPD patients (Group III). The high-resolution CT was performed at three levels (the upper, middle, and lower parts of the lungs).

A Mild Chest Trauma in an Infant who Developed Severe Pulmonary Hemorrhage.

Chest trauma, an important cause of morbidity and mortality, is the second most common cause of death in children under four years of age. Due to the different anatomy and physiology of the respiratory system in childhood, the injuries and consequences of chest trauma are also dissimilar. A seven-month-old male infant presented to the emergency clinic with cyanosis and respiratory distress.

Automatic identification of landmarks for standard slice positioning in brain MRI.

Purpose: To demonstrate a novel automatic slice-positioning technique based on three new anatomical landmarks and to standardize prospective scans by lowering rotational and translational variances.

The effect of cardiac fibrosis on left ventricular remodeling, diastolic function, and N-terminal pro-B-type natriuretic peptide levels in patients with nonischemic dilated cardiomyopathy.

Background: Cardiac fibrosis is common and associated with poor prognosis in patients with heart failure. We investigated the effect of cardiac fibrosis on the left ventricular (LV) diastolic function, functional capacity, LV remodeling, and biochemical parameters in patients with nonischemic dilated cardiomyopathy (NIDC). In addition, we investigated the biochemical and echocardiographic predictors of cardiac fibrosis in this group.

Fragmented QRS complexes are associated with cardiac fibrosis and significant intraventricular systolic dyssynchrony in nonischemic dilated cardiomyopathy patients with a narrow QRS interval.

Background: Myocardial scar causes heterogeneous ventricular activation, which results in fragmentation of QRS complexes on ECG. Myocardial fibrosis in patients with nonischemic cardiomyopathy (NDCM) can be identified as late gadolinium enhancement (LGE) areas on cardiac magnetic resonance (CMR) studies. We investigated the association of fragmented QRS (fQRS) complexes with systolic dyssynchrony and myocardial fibrosis in patients with NDCM.

Lung clearance of 99mTc-DTPA in ankylosing spondylitis.

The association of ankylosing spondylitis (AS) and lung parenchyma abnormalities has been shown in previous studies by radiological and pulmonary function tests. Technetium-99m diethylene triamine pentaacetic acid ((99m)Tc-DTPA) dynamic lung scanning is an easy, noninvasive method to assess alveolar-capillary barrier permeability. We aimed to study the abnormalities in pulmonary clearance of (99m)Tc-DTPA in patients with AS, and the presence of any correlation between this clearance and the radiological and pulmonary function tests.

Echinococcosis involving the liver, retrovesical and seminal vesicle presented with syncope.

Hydatid disease of the urogenital system, especially of the retroperitoneum and seminal vesicles, is a very rare condition. We report a case of hydatid disease located in the liver, retrovesical region and seminal vesicle that was diagnosed incidentally while investigating the etiology of syncope. Transabdominal and transrectal ultrasonography revealed hypoecoic multicystic masses which had thin septations and walls in the liver, retrovesical region and seminal vesicle.

[Double inversion recovery sequence in temporal lobe epilepsy: preliminary results].

Purpose: DIR (double inversion recovery) is a sequence with the hybrid contrast of both FLAIR and STIR sequences, produced by the application of double inversion recovery pulse. It has been suggested that DIR provides high sensitivity to lesions with low T2 contrast. The purpose of this study was to test the hypothesis that DIR sequence is superior to conventional sequences in the identification of mesial temporal sclerosis and other temporal lobe lesions in patients with temporal lobe epilepsy.
