Various corneal diseases, such as hereditary corneal dystrophies, corneal infection, and bullous keratopathy, cause corneal opacity, scarring, and edema, leading to severely decreased visual acuity and loss of vision. These diseases were regarded as corneal opacity diseases, and the decreased visual acuity was considered to be predominantly caused by corneal opacity. The influence of corneal irregular astigmatism on vision has been poorly understood to date, mainly because accurate quantification of irregular astigmatism has been technically challenging...

Cystinosis is an autosomal recessive, lysosomal storage disease characterised by the accumulation of the amino acid cystine in different organs and tissues. It is a multisystemic disease that can present with renal and extra-renal manifestations. In this report, we present the first case of transplanted nephropathic cystinosis in a Tunisian child. A 4-year-old Tunisian boy born to nonconsanguineous parents, was treated in our medical services in 1990 for cystinosis. Since the age of five months, he developed symptoms of severe weight loss, vomiting, dehydration, and polyuria...

INTRODUCTION: Primary posterior capsular plaques can be highly adherent to the posterior capsule leading to possible posterior capsular rupture during attempted removal. Here we describe a novel method for posterior capsular plaque removal using a technique inspired by the experience of retina surgeon in the peeling of membranes from the posterior pole. METHODS: Retinal end-grasping forceps were used to peel the plaque from the posterior capsule. RESULTS: We have performed this technique on 12 eyes with successful removal of the posterior capsular plaque in all instances without compromise of the posterior capsule in any case...

BACKGROUND: Correlation of ST-segment elevation on the 12-lead electrocardiogram (ECG) with the expected affected coronary territory is established in patients with ST-elevation myocardial infarction (STEMI). In patients with non-ST-elevation myocardial infarction (NSTEMI), correlation of ischemic ECG abnormalities with the affected coronary territory has not been well-established. We sought to investigate the correlation of electrocardiographic abnormalities with the location of 1-vessel obstructive coronary artery disease (CAD) in patients with both STEMI and NSTEMI...

Current polytrauma management is multidisciplinary, with Damage Control Surgery (DCS), Damage Control Orthopaedics (DCO) and Damage Control Resuscitation (DCR) being applied in the first few hours after injury. The most severe group of polytrauma patients are those with circulatory instability and massive blood loss as a consequence of unstable pelvic fractures. In treating these patients, of crucial importance is the speed and quality of stabilisation of pelvic fracture fragments. The authors present two case reports of polytrauma patients with unstable pelvic fractures, in whom open reduction and internal fixation was performed on the anterior fracture segment through extended laparotomy in order to stop bleeding into the abdominopelvic cavity as part of the DCS approach...

We describe the case of a patient presenting with ST-segment elevation myocardial infarction due to very late scaffold thrombosis. The patient was already admitted for an elective percutaneous recanalization of a chronically occluded left anterior descending artery (LAD). The procedure was performed according the sub-intimal tracking and re-entry (STAR) technique with 4 bioresorbable vascular scaffolds implantation. However, even though the coronary flow was preserved at the end of the procedure, the dissected segment was only partially sealed at the distal segment of the LAD...

The cerebellum is implicated in social cognition and is likely to be involved in the pathophysiology of autism spectrum disorder (ASD). The goal of our study was to explore cerebellar morphology in adults with ASD and its relationship to eye contact, as measured by fixation time allocated on the eye region using an eye-tracking device. Two-hundred ninety-four subjects with ASD and controls were included in our study and underwent a structural magnetic resonance imaging scan. Global segmentation and cortical parcellation of the cerebellum were performed...

Combining magnetic-resonance imaging (MRI) and proton therapy (PT) using pencil-beam scanning (PBS) may improve image-guided radiotherapy. We aimed at assessing the impact of a magnetic field on PBS-PT plan quality and robustness. Specifically, the robustness against anatomical changes and positioning errors in an MRI-guided scenario with a 30 cm radius 1.5 T magnetic field was studied for prostate PT. Five prostate cancer patients with three consecutive CT images (CT1-3) were considered. Single-field uniform dose PBS-PT plans were generated on the segmented CT1 with Monte-Carlo-based treatment planning software for inverse optimization...

BACKGROUND: Surgical access to the temporal horn is necessary to treat tumors and vascular lesions, but is used mainly in patients with mediobasal temporal epilepsy. The surgical approaches to this cavity fall into 3 primary categories: lateral, inferior, and transsylvian. The current neurosurgical literature has underestimated the interruption of involved fiber bundles and the correlated clinical manifestations. OBJECTIVE: To delineate the interruption of fiber bundles during the different approaches to the temporal horn...
