Introduction: Gastric volvulus occurs primarily when the stomach suffers torsion on itself due to laxity, elongation, or agenesis of the stomach ligamentous attachments or secondary to diaphragmatic hernias. Gastric torsion after sleeve gastrectomy is a rare complication. We present a case report of 3 patients with gastric torsion after sleeve gastrectomy. Case Description/Technique Description...

Objective Maternal ovarian torsion in pregnancy is a rare complication. Its diagnosis is often missed due to the nonspecific clinical features and uncommon objective findings. Ovarian torsion is seen most commonly at first trimester, but can happen second or third trimester. In late pregnancy, especially in the second and third trimesters, the diagnostic accuracy of ultrasound is limited becaus...

Riyad T. Ellati, Parviz K. Kavoussi, Terry T. Turner, Jeffrey J. Lysiak From the Department of Urology, University of Virginia Health System, USA Purpose: This review addresses different aspects of testicular torsion from the clinical perspective as well as the basic cellular and molecular events responsible for the post-torsion testicular changes and pathology, including tissue ischemia-reperf...

Gallbladder torsion is a rare clinical entity and it is a difficult condition to diagnose preoperatively. About 500 cases of gallbladder torsion have been reported since 1898, when Wendel first described gallbladder volvulus. This condition most commonly occurs in elderly women and the symptoms of this disease are largely non-specific and they mimic those of acute cholecystitis. Even with the r...

The zygapophyses and zygosphene-zygantrum articulations of snake vertebrae are hypothesized to restrict or eliminate vertebral torsion. This hypothesis is apparently based solely on the inference of function from structure, despite the limitations of such inferences, as well as contradictory observations and measurements. In this study, I observed and measured axial torsion in gopher snakes, Pi...

CONTEXT AND OBJECTIVE Testicular torsion is a medical and urological emergency because it can lead to loss of the organ. The theory of seasonal testicular torsion occurrence is based on studies from institutions located in cold and temperate regions. The objective here was to determine whether cold weather is associated with higher incidence of testicular torsion in a tropical country, such as ...

The role of electronic excitation in inelastic collisions between ultracold Ca atoms and Ba(+) ions, confined in a hybrid trap, is studied for the first time. Unlike previous investigations, this system is energetically precluded from undergoing inelastic collisions in its ground state, allowing a relatively simple experimental determination and interpretation of the influence of electronic exc...

The torsion index is a positive integer associated by Grothendieck to any connected compact Lie group G [10]. Knowing the torsion index of a group has direct consequences for the integral cohomology of the classifying space BG, the complex cobordism of BG, the Chow ring of BG, and the classification of G-torsors over fields. These applications of the torsion index are summarized in my paper [25...

Background-Left ventricular (LV) torsion is emerging as a sensitive parameter of LV systolic myocardial performance. Aim of the present study was to explore the effects of acute myocardial infarction (AMI) on LV torsion, and to determine the value of LV torsion early after AMI in predicting LV remodeling at 6-month follow-up. Methods and Results-A total of 120 patients with first ST-elevation A...

The aim of this study was to determine whether objective ocular torsion in intermittent exotropia (IXT) changes after recession surgery, and to evaluate the relationship between change in ocular torsion and clinical parameters in IXT. Sixty patients between 3 and 14 years of age underwent lateral rectus (LR) recession for IXT. Digital fundus photographs were obtained from both eyes of each subj...
