Evaluation of forearm arterial repairs: Functional outcomes related to arterial repair.

Background: There are few studies of single forearm arterial injury repair that compare long-term results of intact and obliterated forearm arterial repair. Aim of the present study was to compare long-term results of forearm arterial repair using Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) score and color Doppler ultrasound (CDUS).

Methods: Records of 166 consecutive patients with forearm arterial injury were reviewed, and 30 patients with same injury (ulnar artery, ulnar nerve, and tendon injuries at flexor zone V) were called back for CDUS and QuickDASH scoring.

Caudal Septal Support Versus Strut Graft in Achieving the Desired Lateral Profile in Rhinoplasty.

Nasal tip support is critical to achieve a lasting result in rhinoplasty. In this article, the authors compared the effects of strut grafts (SG) and caudal septum-based nasal tip supporting techniques (CSB-T) in terms of reaching the desired tip projection.Included in this study were 40 patients (24 women and 16 men) who underwent primary open rhinoplasty via transcolumellar incision between January and June 2012.

Comparison of the effects of different vasoactive and antiplatelet drugs on perforator flap viability. An experimental study.

Perforator flaps are very popular in the reconstruction of soft tissue defects. As these flaps generally depend on a single perforator, drugs that increase the perfusion of the flap and/or prevent vascular complications may increase flap survival. In this study, we compared the effects of systemically administered hydralazine (arterial vasodilator via potassium channels), nifedipine (arterial vasodilator via calcium channels), piracetam (antiplatelet and regulator of microcirculation) and alprostadil (vasodilator, antiplatelet, rheological and cytoprotective) on flap survival in a rat epigastric artery perforator flap model.

The Effect of Chemodenervation by Botulinum Neurotoxin on the Degradation of Hyaluronic Acid Fillers: An Experimental Study.

Background: Early degradation is a common complaint for hyaluronic acid fillers. Although the combination of hyaluronic acid fillers with botulinum neurotoxin type A presented improved clinical results, objective measurement of hyaluronic acid volumes has not been previously assessed.

Methods: In this study, the authors have split the calvaria of the rabbit to mimic the glabellar region in humans.

Multiple Subungual Pyogenic Granulomas Following Levothyroxine Treatment.

Pyogenic granulomas are benign vascular lesions that can result from a large number of etiological factors. Drugs are one etiological factor involved in pyogenic granuloma development. In this study we present our experience of multiple pyogenic granulomas following levothyroxine administration suggesting that levothyroxine hormone replacement therapy might play an important role in the formation of pyogenic granuloma.

A missed diagnosis: acute encephalopathy with biphasic seizures and late reduced diffusion.

Acute encephalopathy with biphasic seizures and late reduced diffusion (AESD) is a very rare encephalopathy subtype which is characterized by biphasic seizures and disturbance of consciousness in the acute stage followed in the subacute stage by restricted diffusion in the subcortical white matter and finally resulting in cerebral atrophy on magnetic resonance imaging. Although exact pathogenesis of AESD is uncertain, the etiology of AESD has been attributed to viral and bacterial infection. Here we report a case of AESD in a 15-year-old mentally and motor retarded patient, diagnosed based on clinicoradiological correlation.

A rare complication of rhinoplasty: periorbital emphysema.

Unlabelled: Subcutaneous emphysema is a clinical entity that may be associated with trauma. Rhinoplasty is not an atraumatic procedure. This report presents a case of acute periorbital emphysema after cosmetic rhinoplasty.

Penetrating maxillary sinus injury caused by a construction nail passing through the orbital cavity.

Because of its anatomic position, the orbit is frequently subject to trauma, leading to functional and cosmetic problems. After blunt trauma, orbital fractures can cause functional problems by trapping the periocular tissues without affecting the anatomic integrity of the globe. In comparison, high-energy penetrating injuries can cause serious consequences such as disrupting the lacrimal drainage system and causing loss of vision.

Angiofibrolipoma of the tendon sheath.

We present a rare case of benign tumor of the hand.
