Background: Pyelonephritis can lead to renal scar. Objective: To evaluate the effects of betamethasone in preventing renal scarring in rat model of pyelonephritis. Methods: Sixty three female Sprague-Dawley rats were divided into seven groups. Group A was the control. Mannose-sensitive E coli was directly inoculated into the left kidney exposed under general anesthesia in groups C–G. Group B re...

BACKGROUND Scar burden by late gadolinium enhancement (LGE) cardiovascular magnetic resonance (CMR) is associated with functional recovery after coronary artery bypass surgery (CABG). There is limited data on long-term mortality after CABG based on left ventricular (LV) scar burden. METHODS Patients who underwent LGE CMR between January 2003 and February 2010 within 1 month prior to CABG were...

Scar endometriosis is a rare condition. We report a case of scar endometriosis occurring at the site of a four years old cesarean section scar. She complained of painful sensation during menstruation for 2 years that occurred at the site of her cesarean section surgical scar. On examination, there was a firm nodule measuring 3 × 2 cm in size at the right side of the scar. In view of the possibi...

Most cutaneous wounds heal with scar formation. Ideally, an inconspicuous normotrophic scar is formed, but an abnormal scar (hypertrophic scar or keloid) can also develop. A major challenge to scientists and physicians is to prevent adverse scar formation after severe trauma (e.g. burn injury) and understand why some individuals will form adverse scars even after relatively minor injury. Curren...

BACKGROUND Previous studies have found that BCG vaccination has nonspecific beneficial effects on child survival, especially among children who developed a BCG scar. These studies have mostly been done in settings with a high scar frequency. In rural Guinea-Bissau, many children do not develop a scar; we tested the hypothesis that among BCG-vaccinated children, a vaccination scar was associated...

Two types of microtopographic features (plant scar mounds and plant scar depressions) on surfaces of barren desert pavements provide a unique record of the former presence of large perennial plants. Evidence of bioturbation by burrowing animals extends more than I m beneath each type of plant scar, indicating that both features originated as large bioturbation mounds. Formation of bioturbation ...

Various methods are available for refining scars of the external nose and optimal scar revision frequently requires the utilization of multiple techniques. Differing anatomy of nasal subunits and their underlying structural framework limit surgical options in nasal scar revision compared with other areas of the face. An understanding of a variety of laser technologies and their specific applica...

Scar endometriosis is an under-appreciated or misdiagnosed phenomenon in general surgery and may eventually be more common than reflected in the literature. We herein report five cases of scar endometriosis that were treated in our surgical department one to five years after Caesarean section. Scar endometriosis should be considered when the symptoms are present in a cyclic manner mostly after ...

BACKGROUND This study evaluates a novel dark-blood late gadolinium enhancement (LGE) cardiovascular magnetic resonance imaging (CMR) method, without using additional magnetization preparation, and compares it to conventional bright-blood LGE, for the detection of ischaemic myocardial scar. LGE is able to clearly depict myocardial infarction and macroscopic scarring from viable myocardium. Howev...
