OBJECT
Intramedullary neurenteric cysts (NECs) are exceedingly rare lesions and have been previously reported in case reports. The aim of this study was to determine the clinical manifestations, radiological features, and long-term prognosis of patients with such lesions.

METHODS
The authors retrospectively reviewed the records of 13 patients with an intramedullary NEC. Each patient underwent MRI, laminotomy, and microsurgery. The accurate diagnosis was based on imaging and pathology findings. Each patient's follow-up status was determined through individual office visits and a structured telephone interview.

RESULTS
The series included 7 male and 6 female patients. Progressive or intermittent motor deficit was the main symptom associated with or without pain or sensory disturbance. Five cysts were located in the cervical cord, 1 in the cervicothoracic cord, 3 in the thoracic cord, and 4 in the conus medullaris. Concurrent malformations included scoliosis (3 cases), fusion of rib (1 case), enlarged spinal canal (1 case), tethered spinal cord (1 case), and ectocardia (1 case). Gross-total resection of the cyst was achieved in 8 cases, and subtotal resection (STR) was achieved in 5 cases. All patients were followed up, with a mean duration of 66.5 months. Cyst recurrence was observed in 4 cases after STR. In 2 cases the patients underwent reoperation; the other 2 patients remained clinically stable and did not undergo reoperation. At the last evaluation, neurological function was improved in 11 patients and remained stable in 2 patients.

CONCLUSIONS
Intramedullary NECs should be considered in the differential diagnosis of a middle-aged patient with intermittent neurological symptoms and concurrent malformations. Early surgery is advocated to prevent permanent neurological deficits. When gross-total resection cannot be achieved, maximally safe removal under the protection of intraoperative neuromonitoring is advised. Because of the high risk of cyst recurrence, routine follow-up MRI is needed. If a residual cyst shows obvious regrowth and results in neurological deficits, timely reoperation with a goal of STR should be performed.

OBJECT
The purpose of this study was to determine the efficacy of a modified vertebral column resection for the treatment of thoracolumbar angular kyphosis.

METHODS
A total of 13 patients (8 male, 5 female) with thoracolumbar kyphosis (kyphotic angle > 60°) were included in this study (Group A). There were 3 patients with failure of spinal formation (Type 1 deformity), 6 patients with old thoracic or lumbar compression fracture, and 4 patients with old spinal tuberculosis (including 1 case of T3–5 vertebral malunion). The average preoperative kyphotic angle was 67.3° (range 62°–75°). Each patient underwent an expanded eggshell procedure combined with the closing-opening technique for the treatment of thoracolumbar angular kyphosis. Sixteen patients who were previously treated with a closing-opening wedge osteotomy in the same spine classification group (kyphotic angle > 60°) were used as a control group (Group B).

RESULTS
In Group A, the average (± SD) operative time was 400 ± 60 minutes, and the average blood loss was 960 ± 120 ml. There were no surgery-related complications observed during or after the operations. The average local kyphotic angle was 20.3° (range 18°–24.5°), and the average correction rate was 68.7%. In Group B, the average operative time was 470 ± 90 minutes, and the average blood loss was 2600 ± 1600 ml (range 1200–8200 ml). There were segmental vessels and spinal canal venous plexus injury in 1 case, spinal cord injury in 1 case, dural tearing in 2 cases, pleural rupture in 2 cases, and hemothorax and pneumothorax in 1 case. Each patient had more than 2 years of follow-up. At the latest follow-up examination, the average regional kyphotic angle was 19.9° ± 9.1° (range 19°–34°), and there was no significant loss of correction (p > 0.05). There was greater blood loss and a higher complication rate in Group B than in Group A (p < 0.05).

CONCLUSIONS
An expanded eggshell procedure combined with the closing-opening technique for the treatment of thoracolumbar angular kyphosis resulted in significant reduction of the kyphotic angle, few complications, and good follow-up results. However, a larger series of patients and long-term follow-up results is still required to verify the effectiveness and safety of this method.

Apis mellifera(Hymenoptera: Apidae) drone sperm quality in relation to age, genetic line, and time of breeding
Authors: Rousseau Andrée , Fournier Valérie , Giovenazzo Pierre 
Published: April 2015

AbstractA honey bee (Apis melliferaLinnaeus; Hymenoptera: Apidae) queen’s life expectancy is strongly dependent on the number of sperm she obtains by mating with drones during nuptial flights. Unexplained replacement of queens by the colony and young queens showing sperm depletions have been reported in North America, and reduced drone fertility has been a suspected cause. The aim of this study was to evaluate drone reproductive qualities during the queen-rearing season, from May to August. Drones from two different genetic lines were reared six times during the 2012 beekeeping season at our research centre in Québec (Canada). Semen volume as well as sperm number and viability were assessed at the ages of 14, 21, and 35 days. Results showed (1) a greater proportion of older drones with semen at the tip of the genitalia after eversion; (2) an influence of rearing date on semen production; and (3) no influence of drone genetic line, age or time of breeding on sperm viability. These results highlight the necessity of better understanding drone rearing and how it can be improved to ensure optimum honey-bee queen mating.
The occurrence of Dryocoetes krivolutzkajae (Coleoptera: Curculionidae: Scolytinae) in Canada: a potential pest of cultivated roseroot (Crassulaceae)

Published: April 2015

AbstractDryocoetes krivolutzkajae Mandelshtam (Coleoptera: Curculionidae), a scolytine bark beetle previously known only from the Kamchatka Peninsula, Russia was discovered in Labrador and New Brunswick, Canada. It is unknown whether the Canadian populations represent an introduction or the natural range of D. krivolutzkajae. The habit of this beetle is particular because it is one of the few scolytines that complete their lifecycle within herbaceous roots. This species feeds on the rhizomes of Rhodiola rosea Linnaeus (Crassulaceae) an important natural medicinal plant. Currently it is unknown if, and how rhizome infestation affects the active chemical constituents. The impact of D. krivolutzkajae on the quantity and quality of R. rosea rhizomes requires study.

ABSTRACTBackgroundTrauma registry remains a great problem to most countries that are implementing trauma systems. Nondigital data assessment and storage may lead to information deterioration along the process. In order to verify the missing registry in prehospital trauma rescuers’ form, we ran this study.Study designA prospective observational noncontrolled study with 288 random trauma cases brought to a Level 1 Trauma Center in Curitiba, between May 28th and June 10th 2006. We analyzed data registered in the prehospital rescue team form. The including criteria were all patients delivered to the trauma center by ambulances. The excluding criteria were patients not transported by ambulances and those without the proper form filled out. Statistical analysis was performed using the Chi-square for discrete, and the student's t-test for continuous variables.ResultsTwo hundred and eighty-eight trauma cases were observed. Twelve patients were excluded. Of the 276 patients who met the including criteria, 75% were men with a mean age of 27-year-old. In only 8.34% of times patients were brought by doctors, while in 91.66% by paramedics. 63.4% of patients were traffic injuries victims, followed by 12.31% falls, 6.52% falls from the high, 5.79% gunshot wounds, 5.34% assaults, 3.62% stab wounds, 2.89% others. Impressively, 16 patients (5.89%) had no records of respiratory rate from the prehospital care assessment, 20 (7.24%) had no data of systolic blood pressure and 13(4.71%)had no pulse registry. Furthermore, 31.25% of the RR not registered were abnormal in the hospital admission evaluation, as well as 15% of the SBPs, and 23% of HR. None of the cases had information regarding time from the scene to the hospital.ConclusionElectronic data collection shall make checklists consistently filled out. It is not well understood the importance of registering data for most of healthcare providers working in the field, especially when they do not follow the in-hospital care of trauma patients.How to cite this articleAbreu-Reis P, Tomasich FS, Nasr A, Collaco I.

The Evolution of Liver Injury Diagnosis and Treatment in the Past 50 Years
Authors: Lucas Charles E 
Published: April 2015

ABSTRACTBackgroundDuring the past 50 years many changes have occurred in treating liver injury. Nonoperative therapy (NOT) for blunt penetrating injuries is now common.Study designThis report highlights the current therapy of liver injury.ResultsComplications of NOT include early rebleeding requiring prompt operative intervention; intrahepatic hematoma which becomes infected necessitating drainage; bile peritoneum requiring exploration and drainage; and hemobilia requiring embolization, hepatotomy with ligation, or resection. Operative exposure through a midline incision which can be extended as a median sternotomy is preferred. Prehepatic and intrahepatic packs are helpful. Full mobilization of the right and left triangular ligaments augments exposure. Hemostasis for both blunt and penetrating, usually, is obtained by hepatorrhaphy using the 2’ blunt tipped needle swedged onto a 2-O chromic suture. Through-and-through injuries may require hepatotomy with intrahepatic ligation of cross-linking vessels. Locally destructive wounds may require nonanatomic debridement to the point of healthy liver tissue which is then sutured. Formal segmentectomy, or lobectomy, is seldom needed. Hepatic artery ligation controls deep arterial not involving the portal venous supply. The retrohepatic caval atrial shunt will facilitate hemostasis from central liver injuries involving the hepatic veins or retrohepatic cava.Debridement of emacerated liver tissue should be extended to good liver parenchyma where deep liver sutures help with approximate the edges.Drainage is not used for minor injuries. Closed suctions are best for larger wounds. Common duct drainage should be avoided.ConclusionMost liver injuries are treated by NOT. Operative therapy involves hemostasis, debridement when necessary, and selective drainage.How to cite this articleLucas CE. The Evolution of Liver Injury Diagnosis and Treatment in the Past 50 Years.

Purpose To report the surgical treatment of 3 eyes of 2 patients with bilateral anterior lenticonus due to Alport syndrome using femtosecond laser-assisted cataract surgery (FLACS). Methods Two patients with Alport syndrome presented to our department due to anterior lenticonus in both eyes. We performed FLACS with posterior chamber lens implantation in both eyes of one patient and in one eye of the other patient. Anterior segment morphologic changes were visualized with a Scheimpflug camera, and anterior segment optical coherence tomography preoperatively and 3 months after surgery. Ultrastructure of the cut capsule edges was observed with scanning electron microscopy and compared to the edge of femtosecond laser capsulotomy performed on an otherwise healthy patient with cataract (control). Results The intraocular lens (IOL) postoperative positioning parameters met the international requirements of aspherical and wavefront customized IOLs (tilt <10 degree, decentration <800 μm). Scanning electron microscopy revealed the same characteristics of the cut capsule edges in the Alport and in the control eyes. Conclusions Femtosecond laser cataract surgery can be a safe and successful method for optical rehabilitation of anterior lenticonus in patients with Alport syndrome.

Purpose Cementless press-fit total hip arthroplasty (THA) with the Accolade stem (Stryker Accolade™ TMZF, Mahwah, New Jersey) has demonstrated variable implant survivorship and outcomes. The purpose of this study was to analyse the: 1) implant survivorship; 2) complications; 3) functional outcomes; 4) overall quality of life; and 5) patient expectations and satisfaction following THA with this particular press-fit stem. Methods A prospectively collected database of 222 patients who underwent THA at 7 institutions between 2006 and 2009 using the Accolade stem (Stryker Inc. Mahwah, New Jersey) was evaluated. Harris Hip Score (HHS) and SF-12 were used to assess the outcomes at 2- and 5-year follow-up. Kaplan-Meier survivorship was calculated at 5 years of follow-up. Results The 5-year aseptic and all-cause survivorship rates were 99.4% (95% CI, 96.3 to 99.9%) and 97.9% (95% CI, 94.6 to 99.2%), respectively. At 2 and 5 years postoperatively, the patients demonstrated a mean HHS of approximately 89 points and 92 points, respectively. The mental and physical components of the SF-12 mean score increased with the physical component having a more marked increase. The mental and physical components of the SF-12 score increased to a mean of 46 and 45 points at 2 and 5 years, respectively. At 2-year follow-up, over 90% of patients were satisfied with their outcome in a majority of areas surveyed. Discussion Our results suggest that the use of this press-fit construct results in tremendous improvements in functional and quality of life outcomes, along with excellent survivorship at short- and mid-term follow-up.

Published: April 2015

Introduction Miniaturization and surgical progress in the field of ventricular assist device (VAD) therapy will lead to an increasing use in grown-up patients with congenital heart disease (GUCH). VAD implantation in such patients, especially biventricular VAD (BVAD) placement, can be very challenging, potentially associated with high morbidity and mortality. Methods and Results We report on a 47-year-old male patient in terminal biventricular failure with pulmonary hypertension 40 years after a Mustard procedure. The patient was successfully provided with a HVAD (HeartWare; HeartWare Inc., Framingham, MA, USA) into the systemic ventricle as bridge to transplantation, with the sub-pulmonary ventricle left unsupported. Discussion We present our institutional strategy for VAD selection in these patients and highlight intra-corporeal VAD implantation technique.

Published: April 2015

Purpose As a step to large-scale clinical trials, we conducted a small-scale exploratory study to clarify whether the secondary lumen of the double-lumen (DL) peripherally inserted central catheters (PICCs) could perform as well as the secondary lumen of the DL centrally inserted central catheters (CICCs), with an acceptable complication rate in the perioperative surgery period. Methods Forty thoracic esophageal cancer patients requiring central venous catheterization during the perioperative period were assigned to the DL-PICC (4.5-French, 60-cm) group or the DL-CICC (16-gauge, 30-cm) group, with 1:1 randomization. The primary endpoint was the completion rate of continuous catecholamine infusion via the secondary lumen during the observation period. Results Thirty-two cases (14 cases in the PICC group and 18 cases in the CICC group) were analyzed. Continuous catecholamine infusion via the secondary lumen was completed in all 32 cases. No major complications related to PICC/CICC placement/maintenance were noted in the groups during the median observation period of 6 days. Conclusions The secondary lumen of the DL-PICCs performed as well as the secondary lumen of the DL-CICCs with acceptable safety during the relatively short perioperative period of these thoracic esophageal cancer patients (UMIN Clinical Trial Registry UMIN000008131).

Abstract

Platelet-rich plasma (PRP) is one of many new developments within the expanding field of regenerative medicine. Specialists in areas such as orthopedics, physical medicine and rehabilitation, and rheumatology have been exploring the benefits of this novel therapy. Although PRP therapy remains controversial and has minimal clinical trial support, the use of orthobiologics such as PRP continues to advance as patients seek nonsurgical approaches to acute and chronic musculoskeletal injury and disease. However, academic acceptance as well as insurance reimbursement remain reliant on solid and repeatable positive results from large clinical trials. The authors summarize the evolution of PRP therapy and report on its status.

ObjectivesTo determine whether radiologic assessment of thyroid nodules can potentially help guide clinical management after a cytologic diagnosis of atypia of undetermined significance or a follicular lesion of undetermined significance.MethodsWe identified 41 patients with 41 thyroid nodules initially diagnosed as atypia or follicular lesions of undetermined significance on fine‐needle aspiration that were subsequently definitively diagnosed by either surgical resection or repeated fine‐needle aspiration. All sonograms of nodules were reviewed by 2 blinded board‐certifiedradiologists. Lesions were assessed in 3 ways: (1) Mayo pattern classification as benign, indeterminate, or worrisome for malignancy (Ultrasound Q 2005; 21:157–165); (2) thyroid imaging reporting and data system scores (scale of 1–5) based on 2 different previously published scoring criteria (Park et al [Thyroid 2009; 19:1257–1264] and Kwak et al [Radiology 2011; 260:892–899]); and (3) binary classification as benign or malignant.ResultsOf the 41 nodules, 25 had benign histologic findings, and 16 were malignant. Mayo pattern classification was 100% accurate for the benign score. Lesions with a Mayo score of indeterminate were malignant in 21% of cases (6 of 28) and benign in 79% (22 of 28). Lesions with a Mayo score of malignant were malignant in 91% of cases (10 of 11) and benign in 9% (1 of 11). Thyroid imaging reporting and data system scores had area under the receiver operating characteristic curve values of 0.827 for Park scores and 0.822 for Kwak scores. Radiologist binary classification of thyroid nodules showed 88% overall accuracy.ConclusionsRadiologist assessment of thyroid nodules in cases of atypia of undetermined significance or follicular lesions of undetermined significance is highly predictive of the final diagnosis and can help guide management of thyroid nodules of these pathologic types.

ObjectivesTo evaluate the usefulness of sonography for monitoring the response to glucocorticoid treatment in patients with immunoglobulin G4 (IgG4)–related disease.MethodsWe conducted a retrospective study using sonography in 12 patients with bilateral swollen submandibular glands who had a diagnosis of IgG4‐related disease based on an elevated serum IgG4 level (>135 mg/dL) and histopathologic findings between January 2010 and December 2012. Among these patients, 6 were treated with prednisolone, and the other 6 were placed under observation. B‐mode sonographic examinations of the submandibular glands were performed with or without color Doppler imaging at the initial examination and 6 months later. Findings were compared between the groups (treated and untreated), and their relationship with the treatment response of the primarily involved organs was investigated.ResultsIn the treated group, the submandibular glands of all 6 patients decreased in both size and volume after treatment (average volume ± SD, 27,449.7 ± 24,227.6 to 4609.7 ± 1911.4 mm3; P = .004). The internal echo texture, characterized by multiple hypoechoic foci scattered against a heterogeneous hyperechoic background of submandibular tissue with demarcated hyperechoic lines, with or without hypoechoic tumor formation, disappeared or was obscured in all cases. In addition, the blood flow signals were reduced in all 3 patients who underwent color Doppler sonography, and the response observed on sonography was found to correlate with the IgG4 level and recovery of specific organ involvement. In contrast, in the untreated group, the submandibular glands showed a tendency to increase in both size and volume (average volume, 9326.3 ± 3054.8 to 12,217.4 ± 4605.5 mm3; P= .2) without a decrease in the blood flow signals.ConclusionsSonography is considered useful for evaluating the response to glucocorticoid therapy in patients with IgG4‐related disease of the submandibular glands.
