Background/Aims: Turner syndrome (TS) is associated with increased mortality due to cardiovascular disease and a dramatically higher rate of aortic dissection. The recognition and treatment of hypertension in this population is critical. We sought to assess the ability to detect blood pressure (BP) abnormalities comparing ambulatory blood pressure monitoring (ABPM) with conventional BP measurement methods. We hypothesized that ABPM would improve detection of hypertension and alter management strategies. Methods: Twenty-three girls with TS underwent BP measurements using an automated oscillometric method and a manual mercury sphygmomanometer. Twenty-four-hour ABPM was performed (Spacelabs 90217, Issaquah, Wash., USA). BP values were compared to normative data based on height and sex for ABPM, and for age, height and sex for automated oscillometric and manual measurements. Results: Five (22%) subjects were found to have ambulatory hypertension (3 of these with severe hypertension). Three subjects had prehypertension using ABPM measurements. Only 1 of the 5 patients with ambulatory hypertension was categorized as hypertensive using manual BP measurements. Twelve subjects (52%) had nocturnal hypertension. ABPM data led to a change in medical management of hypertensive patients with initiation of antihypertensive therapy. Conclusions: ABPM is advantageous in TS, as it improves detection of hypertension, identifies those with non-dipping BP patterns, and changes medical management of patients. © 2013 S.

Background: Cilengitide is a selective integrin inhibitor that is well tolerated and has demonstrated biologic activity in patients with recurrent malignant glioma. The primary objectives of this randomized phase 2 trial were to determine the safety and efficacy of cilengitide when combined with radiation and temozolomide for patients with newly diagnosed glioblastoma multiforme and to select a dose for comparative clinical testing. Methods: In total, 112 patients were accrued. Eighteen patients received standard radiation and temozolomide with cilengitide in a safety run-in phase followed by a randomized phase 2 trial with 94 patients assigned to either a 500 mg dose group or 2000 mg dose group. The trial was designed to estimate overall survival benefit compared with a New Approaches to Brain Tumor Therapy (NABTT) Consortium internal historic control and data from the published European Organization for Research and Treatment of Cancer (EORTC) trial EORTC 26981. Results: Cilengitide at all doses studied was well tolerated with radiation and temozolomide. The median survival was 19.7 months for all patients, 17.4 months for the patients in the 500 mg dose group, 20.8 months for patients in the 2000 mg dose group, 30 months for patients who had methylated O6-methylguanine-DNA methyltransferase (MGMT) status, and 17.4 months for patients who had unmethylated MGMT status. For patients aged ≤70 years, the median survival and survival at 24 months was superior to what was observed in the EORTC trial (20.7 months vs 14.6 months and 41% vs 27%, respectively; P =.008). Conclusions: Cilengitide was well tolerated when combined with standard chemoradiation and may improve survival for patients newly diagnosed with glioblastoma multiforme regardless of MGMT methylation status. The authors concluded that, from an efficacy and safety standpoint, future trials of this agent in this population should use the 2000 mg dose. © 2012 American Cancer Society.

Background: Current trends in the management of medial orbital wall fractures are toward the development of transconjunctival incisions and the use of endoscopic-assisted methods. Different authors have suggested variations of the medial transconjunctival approach. Methods: (1) In 30 fresh cadaver orbits, the classic transcaruncular approach was compared with the precaruncular and retrocaruncular approach under magnified dissection. (2) A retrospective analysis was conducted on a series of 20 consecutive patients that underwent primary repair of medial orbital wall fractures using a retrocaruncular approach without endoscopic assistance. Postoperative computed tomography scanswere obtained for all patients andwere evaluated by 3 experienced clinicians. Results: (1) Anatomic dissections showed that all 3 approaches provided excellent exposure of the entire medial orbital wall. The transcaruncular and precaruncular approaches, however, (a) both resulted in exposure of the upper and lower tarsi when incisions greater than 10 mm were used; (b) both required a transition from the preseptal plane to the postseptal plane when combined with inferior fornix incisions. (2) A clinical study of 20 patients showed all reconstructions were possible without endoscopic assistance, resulting in no postoperative complications. Postoperative computed tomography scans showed anatomic orbital reconstruction in all patients judged as excellent by the clinicians. Conclusions: Medial orbital wall fractures can be successfully repaired using transconjunctival incisions without using endoscopes. The retrocaruncular approach surpasses the transcaruncular and precaruncular methods due to its decreased risk of postoperative lid complications and its ability to be directly carried to the inferior conjunctival fornix. © 2016 Wolters Kluwer Health, Inc.

Endovascular abdominal aortic aneurysm repair (EVAR) requires both endovascular and open surgical skills. Although usually performed by a single operating specialist, EVAR may alternatively involve multiple teams from different specialties performing separate procedural components. We examined the relative frequencies of single versus multi-specialty EVAR in the 2005 to 2008 American College of Surgeons National Surgical Quality Improvement Participant Use Datafile and explored the influence of multi-specialty EVAR on 30-day mortality. EVARs were identified and classified as single or multiple-specialty procedures based on Current Procedural Terminology codes. Baseline and procedural characteristicswere compared using χ 2 or Fisher's exact test for categorical variables and t test for continuous variables. The association between multispecialty EVAR and 30-day mortality was examined using a multivariate logistic regression model. Of 7269 EVAR patients identified, 7086 were single and 183 were multi-specialty. Multi-specialty patients had higher frequency of brachial or iliac artery exposure and longer operative times, but were otherwise similar in baseline and procedural characteristics. In the multivariate model, multi-specialty EVAR was associated with increased risk of 30-day mortality (odds ratio 2.35; 95% confidence interval 1.08-5.11; P value 0.031). Multi-specialty participation in EVAR procedures is associated with significantly higher 30-day mortality. Further research is warranted to determine whether multi-specialty participation reflects provider experience, institutional protocols, procedural complexity, non-surgical or other factors.

Intraneural hemangiomas and vascular malformations are rare, with approximately 50 cases reported in the literature. They present a therapeutic challenge; surgical resection can result in damage to the nerve and lesion recurrence is common. We introduce a new framework to classify intraneural vascular anomalies in relation to the anatomic compartments of the nerve and assess amenability to surgical resection.We retrospectively reviewed cases of intraneural hemangiomas and vascular malformations treated at our institution between 2003 and 2013 that had high-resolution 3-T magnetic resonance imaging (MRI). A review of the literature was also performed. Our cases and reports in the literature with available MRI data were sub-categorized according to their relationship to the paraneurium and epineurium of the nerve.Nine patients were identified with intraneural (subparaneurial or subepineurial) vascular lesions. Two patients had a predominantly subparaneurial involvement of the nerve, six patients had predominantly subepineurial involvement, and one patient exhibited extensive involvement in both compartments. Four patients were managed surgically and the rest conservatively. Targeted resection of two subparaneurial hemangiomas provided complete relief of symptoms and freedom from recurrence at 18 month and 24 months respectively. One patient with extensive subepineurial and extraneural vascular malformations did not appear to benefit from sub-total resection with interfascicular dissection. No surgical morbidity was noted in any of the cases.We believe that the subparaneurial compartment-a potential space between the epineurium and paraneurium-provides a tissue plane within which benign vascular lesions can occur. Hemangiomas and vascular malformations are complex and can occupy different intraneural and extraneural compartments. The anatomic framework aids surgical decision-making and ensures that all components of the lesion are considered. We advocate a multimodal approach in the treatment of these rare lesions.

Objective: To evaluate the relationship between early relapse recovery and onset of progressive multiple sclerosis (MS). Methods: We studied a population-based cohort (105 patients with relapsing-remitting MS, 86 with bout-onset progressive MS) and a clinic-based cohort (415 patients with bout-onset progressive MS), excluding patients with primary progressive MS. Bout-onset progressive MS includes patients with single-attack progressive and secondary progressive MS. "Good recovery" (as opposed to "poor recovery") was assigned if the peak deficit of the relapse improved completely or almost completely (patient-reported and examination-confirmed outcome measured $6 months post relapse). Impact of initial relapse recovery and first 5-year average relapse recovery on cumulative incidence of progressive MS was studied accounting for patients yet to develop progressive MS in the population-based cohort (Kaplan-Meier analyses). Impact of initial relapse recovery on time to progressive MS onset was also studied in the clinic-based cohort with already-established progressive MS (t test). Results: In the population-based cohort, 153 patients (80.1%) had on average good recovery from first 5-year relapses, whereas 30 patients (15.7%) had on average poor recovery. Half of the good recoverers developed progressive MS by 30.2 years after MS onset, whereas half of the poor recoverers developed progressive MS by 8.3 years after MS onset (p = 0.001). In the clinic-based cohort, good recovery from the first relapse alone was also associated with a delay in progressive disease onset (p < 0.001). A brainstem, cerebellar, or spinal cord syndrome (p = 0.001) or a fulminant relapse (p < 0.0001) was associated with a poor recovery from the initial relapse. Conclusions: Patients with MS with poor recovery from early relapses will develop progressive disease course earlier than those with good recovery. © 2015 American Academy of Neurology.

Mortality after smoke inhalation-associated acute lung injury (SI-ALI) remains substantial. Age and burn surface area are risk factors of mortality, whereas the impact of patient- and center-level variables and treatments on survival are unknown.We performed a retrospective cohort study of burn and non-burn centers at 68 US academic medical centers between 2011 and 2014. Adult inpatients with SI-ALI were identified using an algorithm based on a billing code for respiratory conditions from smoke inhalation who were mechanically ventilated by hospital day 4, with either a length-of-stay 5days or death within 4days of hospitalization. Predictors of in-hospital mortality were identified usinglogistic regression. The primary outcome was the odds ratio for in-hospital mortality.A total of 769 patients (52.9 18.1 years) with SI-ALI were analyzed. In-hospital mortality was 26%in the SI-ALI cohort and 50%in patients with 20%surface burns. In addition to age > 60 years (OR 5.1, 95%CI 2.53-10.26) and 20%burns (OR 8.7, 95%CI 4.55-16.75), additional risk factors of in-hospital mortality included initial vasopressor use (OR 5.0, 95%CI 3.16-7.91), higher diagnostic-related group-based risk-of-mortality assignment and lower hospital bed capacity (OR 2.3, 95%CI 1.23-4.15). Initial empiric antibiotics (OR 0.93, 95%CI 0.58-1.49) did not impact survival. These new risk factors improved mortality prediction by 9.9%(P< .001).In addition to older age and major surface burns, mortality in SI-ALI is predicted by initial vasopressor use, higher diagnostic-related group-based risk-of-mortality assignment, and care at centers with< 500 beds, but not by initial antibiotic therapy.

Purpose: The purpose of this study was to determine if loss of serine protease HtrA1 in endometrial cancer will promote the invasive potential of EC cell lines. Experimental design: Western blot analysis and immunohistochemistry methods were used to determine HtrA1 expression in EC cell lines and primary tumors, respectively. Migration, invasion assays and in vivo xenograft experiment were performed to compare the extent of metastasis between HtrA1 expressing and HtrA1 knocked down clones. Results: Western blot analysis of HtrA1 in 13 EC cell lines revealed complete loss of HtrA1 expression in all seven papillary serous EC cell lines. Downregulation of HtrA1 in Hec1A and Hec1B cell lines resulted in a three- to fourfold increase in the invasive potential. Exogenous expression of HtrA1 in Ark1 and Ark2 cells resulted in three- to fourfold decrease in both invasive and migration potential of these cells. There was an increased rate of metastasis to the lungs associated with HtrA1 downregulation in Hec1B cells compared to control cells with endogenous HtrA1 expression. Enhanced expression of HtrA1 in Ark2 cells resulted in significantly less tumor nodules metastasizing to the lungs compared to parental or protease deficient (SA mutant) Ark2 cells. Immunohistochemical analysis showed 57% (105/184) of primary EC tumors had low HtrA1 expression. The association of low HtrA1 expression with high-grade endometrioid tumors was statistically significant (P = 0.016). Conclusions: Collectively, these data indicate loss of HtrA1 may contribute to the aggressiveness and metastatic ability of endometrial tumors. ©2010 AACR.

In recent years, development of computer graphics and haptic feedback technology enabled the use of virtual reality. Virtual reality provides the opportunity to combine 3D visual imagery with interactivity, visual, and tactile realism. Robotic-assisted orthopedic surgery is defined as the use of computers and robotic technology to assist the orthopedist in providing musculoskeletal care, in which machine has the capability of precision and accuracy. Robotic-assisted orthopedic surgery is used in simulating diagnosis, preoperative and intraoperative planning, and actual surgery. One of the main areas for computer-assisted surgical applications is unicompartmental or bicompartmental knee arthroplasty, in which the clinical efficacy is improved by providing enhanced component positioning with dynamic ligament balancing.
