Is There a Relationship Between Paratracheal Air Cysts and Upper Lobe Fibrosis?

Objective: The purpose of this study was to determine the characteristics of paratracheal air cysts (PACs) and their relationship with upper lobe pulmonary fibrosis.

Materials And Methods: The routine thoracic computed tomography scans of 3549 patients carried out between January 2014 and April 2015 were retrospectively evaluated. The presence, location, structural characteristics (uniloculated or multiloculated), number of cysts, and anterior-posterior and transverse dimensions of the PAC and its communication with the tracheal lumen were evaluated.

Twin Reversed Arterial Perfusion (TRAP) Sequence; Characteristic Gray-Scale and Doppler Ultrasonography Findings.

Twin reversed arterial perfusion (TRAP) sequence is a syndrome with poor prognosis, seen only in monochorionic monozygotic twin pregnancies. The incidence is one in 35.000 births and one in 100 monozygotic twin pregnancies.

Are there any effects of chronic carbon monoxide exposure on argyrophilic nucleolar-organizing region-associated protein synthesis in rat myocardium?

The aims of the study are to detect whether there are any possible effects of chronic carbon monoxide (CO) exposure on the argyrophilic nucleolar-organizing region (AgNOR)-associated protein synthesis and evaluate any possible relationship between the amount of AgNOR protein and the level of myocardial injury also and between AgNOR and histopathological evaluation methods. Adult male albino Wistar rats (n = 18) were randomly divided into three groups (groups A, B, and C). Group A served as control, while groups B and C were rats exposed to CO gas chronically (1000 and 3000 ppm CO concentration with a flow rate of 4 L/min for 30 min/day for 7 days, respectively).

Do the variations in renal pelvic angles play a role in the formation of renal stone? A computed tomography study.

Objective: In this study, we aimed to investigate the effect of variations in renal pelvic angle on urinary calculi development.

Materials And Methods: A total of 2456 unenhanced abdominal CT scans were retrospectively evaluated and 262 kidneys of 131 patients were compared. Patients included in this study were identified and qualified as follows: Having unilateral calculi, having no calculi or a history of calculi in contra-lateral side and having totally normal renal morphology.

Characteristic imaging findings of duodenal perforation.

Two patients were admitted to emergency room with complaint of abdominal pain with abrupt onset and retroperitoneal free air was detected in pararenal area on CT. In this paper, characteristic CT findings of patients diagnosed with duodenal perforation are presented under the light of literature data.

Lumbar Morel-Lavallee lesion after trauma: a report of 2 cases.

Morel-Lavallee syndrome is a posttraumatic soft tissue injury in which the subcutaneous tissue is broken off from the underlying fascia, creating a cavity filled with hematoma and liquefied fat. It commonly occurs over the greater trochanter and, rarely, may also occur in the lumbal region.Morel-Lavallee syndrome can be often diagnosed late because of ommitted diagnosis in emergency services.

Whole-exome sequencing identifies homozygous GPR161 mutation in a family with pituitary stalk interruption syndrome.

Context: Pituitary stalk interruption syndrome (PSIS) is a rare, congenital anomaly of the pituitary gland characterized by pituitary gland insufficiency, thin or discontinuous pituitary stalk, anterior pituitary hypoplasia, and ectopic positioning of the posterior pituitary gland (neurohypophysis). The clinical presentation of patients with PSIS varies from isolated growth hormone (GH) deficiency to combined pituitary insufficiency and accompanying extrapituitary findings. Mutations in HESX1, LHX4, OTX2, SOX3, and PROKR2 have been associated with PSIS in less than 5% of cases; thus, the underlying genetic etiology for the vast majority of cases remains to be determined.

Colloid cyst mimicking intracranial hemorrhage after head trauma.

Trauma patients consist vast majority of the patients who admit to emergency department, and most of them have a head trauma. A 58-year-old patient was taken to emergency department with head trauma, and a hyperdense lesion neighboring to third ventricle was detected. A diagnosis of colloid cyst was made in the patient who was being followed up for hemorrhage.

CT and MR Imaging Characteristics of Intravestibular and Cerebellopontine Angle Lipoma.

Intracranial lipoma is an uncommon entity. A rare type of tumor in the internal auditory canal (IAC) and the cerebellopontine angle (CPA) is lipoma. There are a few case reports in the literature related to intravestibular lipoma.

Breast arterial calcifications and carotid intima-media thickness and haemodynamics: Is there any association?

Objective: In this study, we aimed to research the relation between breast arterial calcifications (BACs) detected on mammography and two well-known markers of cardiovascular diseases-carotid artery intima-media thickness (C-IMT) and haemodynamics parameters like carotid peak-systolic velocity (PSV), end-diastolic velocity (EDV) and resistive index (RI).

Methods: The study group consisted of 50 consecutive BAC (+) women and the control group consisted of 55 BAC (-) women. In all participants, BAC was diagnosed using mammography and C-IMT was measured using B-mode and Doppler ultrasonography.

Role of ultrasonography with color-Doppler in the emergency diagnosis of acute penile fracture: a case report.

Penile fracture is the rupture of tunica albuginea, typically resulting from blunt trauma, intercourse, or penile manipulation. Diagnosis is made clinically. Ultrasound is not used frequently in diagnosis of penile fracture but it provides a fast, non-invasive alternative to more often used MRI and cavernography.

Complex fracture of the clivus after head trauma.

Clivus fracture (CF), which is usually reported to accompany with head trauma, has high mortality rates. Early diagnosis of CF is rare because of high mortality rates and inadequate urgent radiologic techniques; however, diagnosis rates are increasing with computed tomography images obtained in high resolution and thin sections. In this article, radiologic and clinical features of 2 patients who were detected to have longitudinal CF after head trauma are presented and accompanying pathologies and its importance for prognosis are discussed under the light of literature data composed of a small number of reports.

Role and importance of Doppler ultrasound in the diagnosis of pulmonary sequestration: report of two adolescent cases.

Pulmonary sequestration is a rare pulmonary parenchymal anomaly. The localization of the aberrant artery and its relation with sequestration are of importance in the process of diagnosis in the preoperative period. The feeding artery can be identified by color Doppler ultrasonography.
