PURPOSE: Spring-assisted cranioplasty is performed to correct the long and narrow head shape of children with sagittal synostosis. Such corrective surgery involves osteotomies and the placement of spring-like distractors, which gradually expand to widen the skull until removal about 4 months later. Due to its dynamic nature, associations between surgical parameters and post-operative 3D head shape features are difficult to comprehend. The current study aimed at applying population-based statistical shape modelling to gain insight into how the choice of surgical parameters such as craniotomy size and spring positioning affects post-surgical head shape...

Inflammation, fibrosis and perineural adhesions with the surrounding tissue are common pathological processes following nerve injury and surgical interventions on peripheral nerves in human patients. Furthermore, these signs can reoccur following external neurolysis, currently the most common surgical treatment, thus leading to renewed nerve function impairment and chronic pain. To enable a successful evaluation of new therapeutic approaches, it is crucial to use a reproducible animal model that mimics the main clinical symptoms occurring in human patients...

INTRODUCTION AND HYPOTHESIS: Increased incidences of complications related to the use of mid-urethral slings (MUS) for the treatment of stress urinary incontinence resulted in both the Food and Drug Administration (FDA) and Health Canada issuing advisories in 2008 and 2010 respectively. The purpose of this study was to assess the effect these advisories had on the number of surgeons performing MUS surgery and post-surgical complications in Calgary, Canada. METHODS: In this study, we conducted a retrospective analysis of administrative data between 2006 and 2011...

Uretero-intestinal anastomosis (UIA) is one of the most critical points for the occurrence of severe complications of intestinal urinary diversion. Perfection of the current techniques and development of new UIA methods are motivated by the effort to reduce both early and late post-surgical complications. The necessity of using antireflux UIA, especially with an orthotopic neobladder, is controversial: according to some authors, antireflux UIA of any type generally increases, in comparison with reflux UIA, the risk of obstruction that endangers renal function more than the urine reflux itself...

BACKGROUND: Many patients who undergo anterior cruciate ligament (ACL) reconstructive surgery develop post-traumatic osteoarthritis (PTOA). ACL reconstructive surgery may not fully restore pre-injury joint biomechanics, thereby resulting in further joint damage and contributing to the development of PTOA. In an ovine model of idealized ACL reconstruction (ACL-R), it has been shown that signs of PTOA develop within surgical joints by 20 weeks post-surgery. The aim of the present study was to investigate whether altered kinematics contribute to early PTOA development within ACL-R joints of the ovine injury model by comparing the gait of these surgical animals to the gait of a stable normal control group, and an unstable injury group in which the ACL and medial collateral ligament (MCL) had been transected...

Chronic kidney disease (CKD) exacerbating vascular disease poses a major challenge to nephrology. Surgically placed vascular fistulas, as an aid to hemodialysis prior to kidney transplant, have extended many lives, while post-surgical restenosis closure of the fistula by smooth muscle cells affects many lives. When post-surgical restenosis is developed, palliative measures are almost always surgical: there are no effective drug treatments. In this study, we offer a testable hypothesis that effects of CKD on widely distributed vascular diseases and the phenomenon of fistula restenosis are both driven by the pathologic creation of non-dividing smooth muscle cells via asymmetric division of exponentially increasing metakaryotic stem cells...

EDITORIAL
Morris Gordon
5-Aminosalicylates are a class of anti-inflammatory agents that have been used for decades in inflammatory bowel disease. Whilst they are first line for induction and an option for maintenance of remission in ulcerative colitis, the picture in Crohn's disease is variable. For maintenance of remission, key Cochrane systematic reviews have found conflicting results between the medical and surgical induced contexts. In this piece, the possible reasons for this are considered. It is proposed that clinicians should consider 5-aminosalicylates agents an option to maintain remission post-surgery...

Intracardiac thrombosis is a rare complication of Behçet's disease (BD), which may manifest as intracardiac tumor. In half of cases, its detection precedes the diagnosis of MB. High mortality rates may be related to post-surgical complications and/or pulmonary arteries involvement. We report the case of a 29-year old young patient, with a previous history of bipolar aphthosis, who underwent surgery after the detection of right atrium and ventricle tumor. Anatomo-pathological examination showed thrombus and MB was diagnosed in the postoperative period...

Ectopic varices include all varices except esophageal or gastric varices and comprise large portosystemic venous collaterals that occur anywhere in the abdomen. Ectopic varices are relatively rare; however, approximately 5% are related to gastrointestinal bleeding. Ectopic varices usually occur in the rectum, duodenum, or colon, and portal hypertension is the most common cause. Hemodynamic profiles of ectopic varices remain unknown, and extensive bleeding from these structures occurs because diagnosis and treatment are difficult...

BACKGROUND: Subthalamic deep brain stimulation (STN-DBS) is an established treatment for the motor complications of Parkinson's disease (PD) and may have beneficial effects on non-motor symptoms (NMS). However, the acute effect of STN stimulation on NMS has only been explored in small PD cohorts with short post-surgical follow-up. OBJECTIVE: To study NMS response to an acute stimulation challenge in an STN-DBS PD population with a medium/long-term post-surgical follow-up...

BACKGROUND: Cervical radiculopathies are rarely caused by vertebral artery loop formation, which is estimated to be present in less than 3% of patients. It is uncertain what causes the loop formation: some propose an association with spondylotic changes or trauma, whilst others suggest hypertension and atherosclerosis may be responsible. CASE REPORT 1: A 35-year-old male patient presented with signs and symptoms of cervical radiculopathy that was not improved with anterior cervical discectomy and fusion surgery performed 2 years beforehand...

BACKGROUND: Anecdotal reports support the position that the adulticidal heartworm treatment utilizing doxycycline and Advantage Multi®/Advocate® for Dogs (10% imidacloprid + 2.5% moxidectin) has successfully converted antigen-positive dogs to antigen-negative. To date, no controlled experimental studies have demonstrated the adulticidal efficacy of this treatment regimen. The aim of this study was to evaluate the parasitological and clinical efficacy of Advantage Multi® for Dogs (IMD + MOX) and doxycycline in heartworm-infected beagles...

External femoral derotation osteotomy (FDO) is an orthopaedic intervention to correct increased femoral anteversion and associated excessive internal hip rotation and internal foot progression during gait in children with cerebral palsy. The resulting functional issues may include clearance problems and hip abductor lever-arm dysfunction. The purpose of this study was to evaluate long-term gait outcomes of FDO. Twenty ambulatory patients (27 sides) with cerebral palsy who underwent pre-operative (P0) and a one year post-operative (P1) gait analysis as part of the standard of care had a second post-operative analysis (P2) approximately 11 years post-surgical intervention...

Bilateral pedicle stress fractures are rare even in the elderly. Bilateral pedicle fractures are due to post-surgical complications at the level of fusion or stress related activities in most cases. The authors describe a unique case of adjacent L4 bilateral pedicle fractures, which developed 4 years after anterior lumbar interbody fusion with bone cement augmented screw fixation at the L5-S1 level. As far as the authors' knowledge, no similar case has been previously reported in the literature. The pathophysiological mechanism of this rare entity is discussed with review of relevant literature...

REVIEW
Yong Jun Cho, Suk Hyung Kang
Cranioplasty is an in evitable operation conducted after decompressive craniectomy (DC). The primary goals of cranioplasty after DC are to protect the brain, achieve a natural appearance and prevent sinking skin flap syndrome (or syndrome of the trephined). Furthermore, restoring patients' functional outcome and supplementing external defects helps patients improve their self-esteem. Although early cranioplasty is preferred in recent year, optimal timing for cranioplasty remains a controversial topic. Autologous bone flaps are the most ideal substitute for cranioplasty...

Immunoglobulin D multiple myeloma is a rare type of multiple myeloma that usually presents as bone pain, fatigue, or weight loss. We report a case of immunoglobulin D multiple myeloma in a 53-year-old Caucasian male patient with previous medical history of anaplastic oligodendroglioma status post-surgical resection who was evaluated for back pain while mowing the lawn. His physical examination showed tenderness over the lower thoracic vertebrae with no sensory or motor impairment. Initial lab investigations showed normocytic anemia and hypercalcemia with low parathyroid hormone...

IgG4 related thoracic aortitis is a recent addition to the differential diagnosis for inflammatory aortic disease - a condition which is often underappreciated until complications arise such as aneurysmal formation or aortic dissection. Currently, IgG4 aortitis remains a post-surgical diagnosis reliant on positive immunohistochemistry findings. Management is guided by the extent of disease involvement, which can be gauged by serum IgG4 levels and radiological findings. Options include surgical resection, corticosteroid therapy and steroid-sparing agents to prevent relapses...
