OBJECTIVES/HYPOTHESIS: Reconstruction of craniofacial cartilagenous defects are among the most challenging surgical procedures in facial plastic surgery. Bioengineered craniofacial cartilage holds immense potential to surpass current reconstructive options, but limitations to clinical translation exist. We endeavored to determine the viability of utilizing adipose-derived stem cell-chondrocyte co-culture and three-dimensional (3D) printing to produce 3D bioscaffolds for cartilage tissue engineering...

BACKGROUND AND OBJECTIVES: Major ankle surgery causes intense postoperative pain, and whereas the importance of a sciatic nerve block is well established, the clinical significance of a supplemental saphenous nerve block has never been determined in a prospective, randomized, double-blind, placebo-controlled trial. We hypothesized that a saphenous nerve block reduces the proportion of patients experiencing significant clinical pain after major ankle surgery. METHODS: Eighteen patients were enrolled and received a popliteal sciatic nerve block...

Renin-angiotensin-system blockers are thought to increase the risk of acute kidney injury after surgery and haemorrhage. We found that Losartan does not cause renal cortical hypoxia after haemorrhage in rats because of decreased renal vascular resistance, but did not evaluate resuscitation. AIM: Study Losartan´s effect on renal cortical and medullary oxygenation, and norepinephrine´s vasopressor effect in a model of resuscitated haemorrhage. METHOD: After seven days Losartan (60 mg/kg/day) or control treatment, male Wistar rats were haemorrhaged 20 % of the blood volume and resuscitated with Ringer's Acetate...

Body dysmorphic disorder (BDD) is a preoccupation with a slight or imagined flaw in appearance that causes significant distress and impairment in daily functioning. The disease is more prevalent among patients who seek aesthetic procedures as compared with population standards or individuals that are not interested in aesthetic surgery. Several studies have indicated that BDD symptoms typically worsen after an aesthetic procedure because the preoccupation shifts to a different body area. This article discusses the demographic and clinical features, psychiatric comorbidity, assessment, differential diagnosis, and management of BDD...

Patients who have suffered ACL injury are more likely to develop early onset post-traumatic osteoarthritis despite reconstruction. The purpose of our study was to evaluate the longitudinal changes in the tibiofemoral cartilage contact area size and location after ACL injury and reconstruction. Thirty-one patients with isolated unilateral ACL injury were followed with T2 weighted Fast Spin Echo, T1ρ and T2 MRI at baseline prior to reconstruction, and 6 months, 1 year, and 2 years after surgery. Areas were delineated in FSE images with an in-house Matlab program using a spline-based semi-automated segmentation algorithm...

OBJECTIVE: Pituicytomas and granular cell tumours (GCTs) of the neurohypophysis are considered non-adenomatous neoplasms in the sellar region. The association between hormone hypersecretion and the tumours is seldom discussed and unclear. Therefore, we attempt to investigate this association based on our experience and a review of the literature. METHODS: We report three patients who presented with Cushing's syndrome- or acromegaly-like symptoms at our institution...

We present the case of a 40-year-old female who presented to the General Surgery clinic due to a single episode of abdominal pain which required a visit to the Emergency Department. The patient had undergone surgery during childhood due to the suspicion of a hepatic hydatid cyst. However, an intraoperative cholangiography identified a small, non-complicated biliary cyst. Therefore, a hepatic resection was not performed. The patient did not undergo follow-up of the lesion.
