Arch Expansion Efficiency of Coaxial Tubular Superelastic Nickel-Titanium in Comparison to Single-Stranded Superelastic Nickel-Titanium While Relieving Mandibular Anterior Crowding: A Randomized Controlled Study.

Aim: The aim of the study is to compare the efficiency of six-stranded coaxial tubular superelastic nickel-titanium (NiTi) archwire and a single-stranded wire in relieving anterior mandibular crowding.

Materials And Methods: This double-blind randomized study included 40 patients, categorized into two groups: Sentalloy round group and Speed tubular supercable group (20 each). After taking alginate impressions, the allocated archwire was engaged.

Platelet-rich Plasma and Incidence of Alveolar Osteitis in High-risk Patients Undergoing Extractions of Mandibular Molars: A Case-control Study.

Background: To evaluate the efficiency of platelet-rich plasma (PRP) on the incidence of alveolar osteitis (AO) in patients with potential risk factors for the development of AO.

Materials And Methods: This study was conducted in 150 patients visiting the outpatient department of oral and maxillofacial surgery. Patients with potential risk factors for the development of AO which included smokers, alcoholics, postmenopausal women, patients on oral contraceptives, pericoronitis, and bruxism were included for the study.

Delayed Exercise Is Ineffective at Reversing Aberrant Nociceptive Afferent Plasticity or Neuropathic Pain After Spinal Cord Injury in Rats.

Neuropathic pain is a debilitating consequence of spinal cord injury (SCI) that correlates with sensory fiber sprouting. Recent data indicate that exercise initiated early after SCI prevents the development of allodynia and modulated nociceptive afferent plasticity. This study determined if delaying exercise intervention until pain is detected would similarly ameliorate established SCI-induced pain.

Exercise dependent increase in axon regeneration into peripheral nerve grafts by propriospinal but not sensory neurons after spinal cord injury is associated with modulation of regeneration-associated genes.

Insufficient regeneration of central nervous system (CNS) axons contributes to persisting neurological dysfunction after spinal cord injury (SCI). Peripheral nerve grafts (PNGs) support regeneration by thousands of injured intraspinal axons and help them bypass some of the extracellular barriers that form after SCI. However this number represents but a small portion of the total number of axons that are injured.

The superior vena cava syndrome: late presentation after hemodialysis catheter removal.

The superior vena cava (SVC) syndrome is due to obstruction of the SVC and may present by dyspnea, chest pain, cough, headache, dysphasia, and symptoms of increased intracranial pressure; however, the affected patients can be asymptomatic. Numerous collateral veins are often seen on the upper chest, arms and neck. The syndrome may be caused by prolonged use of indwelling catheters, but is an infrequently reported complication in the hemodialysis patients.
