Objective— To evaluate outcome after transanal rectal pull‐through amputation of single colorectal adenocarcinoma and in situ carcinoma (Tis) in dogs.Study Design— Retrospective case series.Animals— Dogs (n=11) with colorectal cancer.Methods— Full‐thickness colorectal amputation by either simple transanal (7 dogs) or combined abdominal–transanal (4) pull‐through technique.Results— Adenocarcinoma (8) and Tis (2) were removed with 3–6 cm of grossly normal tissue, cranial and caudal to the tumor, or in 1 Tis with 2 cm grossly normal tissue, cranial and caudal. Two dogs that had a combined abdominal–transanal approach died within 4 days. In the other dogs, postoperative complications included short‐term tenesmus (6 dogs), rectal bleeding (11), rectal stricture (3), and long‐term fecal incontinence (1). Postoperative recurrence and metastatic rates for adenocarcinoma were 18.2% and 0%, respectively. Median disease‐free interval and survival time were not reached. Mean disease‐free and overall survival times were 44.3 and 44.6 months (range, 0–75 months), respectively.Conclusion— En bloc excision of colorectal Tis and adenocarcinoma may be followed by a long survival. Complications of the transanal approach are usually moderate and self‐limiting, but complications are more common and severe when more extensive resections are performed through a combined abdominal–transanal approach.Clinical Relevance— Transanal rectal pull‐through amputation is suitable for en bloc resection of colorectal neoplasia. A combined abdominal–transanal approach should be reserved for tumors extending from the mid‐cranial region of the rectum to the descending colon.

Authors: KRAMER ALON , WALSH PETER J. , SEGUIN BERNARD 
Published: July 2008

Objective— To review and describe the surgical procedure of hemipelvectomy in dogs and cats.Study Design— Descriptive report.Animals— Dogs and cats.Methods— Anatomic surgical technique description and PubMed literature search.Results— Hemipelvectomy is an involved, aggressive surgical procedure that must be tailored to each specific clinical case. Thorough preoperative assessment and planning, as well as considerations for closure options are critical for a successful outcome. Although outcome data are scant, the prognosis after hemipelvectomy correlates to the underlying disease process. Proactive postoperative analgesia and slower return to function are important factors in patient management.Conclusions— With careful pre‐ and postoperative planning, hemipelvectomy can be used successfully in dogs and cats.Clinical Relevance— Hemipelvectomy in the dog and cat is a viable treatment option for selected neoplastic and traumatic conditions.
Laparoscopic Adrenalectomy for Treatment of Unilateral Adrenocortical Carcinomas: Technique, Complications, and Results in Seven Dogs
Authors: JIMÉNEZ PELÁEZ MANUEL , BOUVY BERNARD M. , DUPRÉ GILLES P. 
Published: July 2008

Objective—To investigate the feasibility of, and outcome after, laparoscopic adrenalectomy in dogs with unilateral adrenocortical carcinoma.Study Design—Case series.Animals—Dogs (n=7) with Cushing's syndrome caused by unilateral adrenocortical carcinoma.Methods—Laparoscopic adrenalectomy with the dog in lateral recumbency on the unaffected side. Three 5‐mm portals (1 laparoscopic portal, 2 instrument portals) were placed in the paralumbar fossa. A fourth instrumental portal (5–12 mm) was placed above the kidney. After dissection and hemostatic control of the phrenicoabdominal vein, the adrenal gland was carefully dissected or when there was capsule fragility, necrotic content was partially aspirated. The remaining glandular tissue was removed through the 12‐mm trocar site.Results—Dogs with unilateral adrenocortical carcinoma (3 right‐sided, 4 left‐sided) without invasion of the caudal vena cava were successfully operated by laparoscopic approach. There were no significant intraoperative complications; 2 dogs died within 48 hours of surgery because of respiratory complications. Five dogs were discharged 72 hours after surgery, and signs of hyperadrenocorticism disappeared thereafter (survival time ranged from 7 to 25 months).Conclusions—Laparoscopic adrenalectomy is feasible in dogs with either right‐ or left‐sided adrenocortical carcinoma not involving the caudal vena cava.Clinical Relevance—When performed by experienced surgeons, laparoscopic adrenalectomy offers a minimally invasive alternative to open laparotomy or retroperitoneal surgery for the treatment of unilateral adrenocortical carcinoma in dogs.

Published: July 2008

Objective— To evaluate the efficacy of cryosurgery for treatment of skin and subcutaneous tumors in dogs and cats.Study Design— Prospective study.Animals— Dogs (n=20), cats (10).Methods— Cutaneous or subcutaneous tumors were treated by liquid nitrogen cryosurgical spray (1 cm from target tissue at 90° until a 5‐mm halo of frozen tissue was achieved) for 15–60 seconds. Malignant lesions had 3 freeze–thaw cycles benign tumors, 2 cycles. The second or third freeze cycle was performed after complete thaw of the preceding freeze. Wounds healed by second intention. Follow‐up was weekly for 1 month and then twice monthly until wounds healed, and final outcome was determined by telephone interview of owners.Results— Tumor size ranged from 0.3 to 11 cm diameter with 28 (60%) being 0.3–1 cm; 8 (17%) 1.1–3 cm, and 11 (23%) >3.4 cm. Complications included edema, erythema and for extremity lesions, pain and lameness. Treated lesions (n=47) had an overall remission of 98% (mean follow‐up, 345±172.02 days [range, 150–750 days]). One malignant peripheral nerve sheath tumor recurred 7 months after cryosurgical treatment.Conclusion— Cryosurgery is an efficient method for treatment of skin and subcutaneous tumors in dogs and cats.Clinical Relevance— Cryosurgical ablation is an effective means of treating small cutaneous or subcutaneous tumors in dogs and cats, especially in older animals where wound closure or cosmetic outcome might limit surgical excision alone.

Objective— To describe the clinical features and determine oncologic outcome and prognostic factors for dogs with primary tumors of the osseous chest wall.Study Design— Historical cohort.Animals— Dogs (n=39) with spontaneous tumors involving the chest wall.Methods— Medical records were reviewed for dogs with rib and/or sternal tumors treated by chest wall resection and reconstruction. Signalment, preoperative clinical features, reconstruction technique, and oncologic outcome (local tumor recurrence, metastasis, and survival time) were determined from medical records and by telephone contact with owners and referring veterinarians. Oncologic outcome and prognostic factors were determined using Kaplan–Meier survival analysis and Cox proportional hazards. Logistic regression was used to determine if increased serum alkaline phosphatase (ALP) concentration was associated with tumor type.Results— Of the 39 dogs with tumors arising from the chest wall, 25 had osteosarcoma, 12 had chondrosarcoma, and 2 dogs had hemangiosarcoma. Median survival time (MST) for dogs with rib osteosarcoma was 290 days. Increased activity of total ALP significantly decreased survival in dogs with osteosarcoma (210 days versus 675 days, P=.0035). MST for dogs with rib chondrosarcoma was not reached (mean 1301 days) and survival was significantly greater than all other types of rib tumors (P=.0321).Conclusion— Rib tumors should be resected with wide margins to decrease the risk of incomplete excision, because local tumor recurrence has a significant impact on the survival time. The prognosis for dogs with rib chondrosarcoma is very good, but guarded for other types of tumors.Clinical Relevance— Osteosarcoma and chondrosarcoma are the most common primary tumors of the chest wall. Prognosis for dogs with primary rib chondrosarcoma is very good with surgery alone, but surgery and adjunctive chemotherapy is recommended for dogs with primary rib osteosarcoma and the prognosis remains guarded.

Authors: JUTLEY RAJWINDER S. , WALLER DAVID A. , LOKE IAN , SKEHAN DOUGLAS , NG ANDRE , STAFFORD PETER , CHIN DEREK , SPYT T. J. 
Published: July 2008

Background: To study the feasibility and efficacy of video‐assisted thoracoscopic (VAT) placement of the left ventricular pacing lead for cardiac resynchronization therapy (CRT) where the conventional transvenous coronary sinus approach has failed.
Methods: Seventeen patients underwent the VAT procedure. Indications for CRT were ischemic cardiomyopathy in six patients and nonischemic cardiomyopathy in 11. The procedure was performed under general anesthesia with single‐lung ventilation. Three 2‐cm incisions were used on the left chest wall to place the screw‐in lead near the obtuse marginal arteries high on the lateral wall of the left ventricle (LV).
Results: The VATS approach was successful in 13/17 (76%) patients. Median procedure time was 75 minutes (range 55–135). A learning curve was observed that appeared to plateau at 75 minutes procedure time after four cases. Median length of hospital stay was 2 days (range 2–8) with one patient requiring intensive care. Satisfactory thresholds and impedances of 2.3 ± 0.9 V/0.5 ms and 560 ohms, respectively, were achieved at mean follow‐up of 226 days. All patients reported symptomatic benefit with reduction in New York Heart Association score from III preoperatively to II postoperatively.
Conclusions: VAT placement of the epicardial pacing lead is feasible, safe, and efficacious. It should be considered in cases where the transvenous route has failed or as an alternative in prolonged or hazardous transvenous procedures.

Background: Lack of stable access to all desired ablation target sites is one of the limitations for efficacious circumferential left atrial (LA) pulmonary vein (PV) ablation. Targeting that, new catheter navigation technologies have been developed. The aim of this study was to describe atrial fibrillation (AF) mapping and ablation using manually controlled steerable sheath catheter navigation and to compare it against an ablation approach with a nonsteerable sheath.
Methods and Results: In this case‐control‐analysis 245 consecutive patients (controls) treated with circumferential left atrial PV ablation were matched with 105 subsequently consecutive patients (cases) ablated with a similar line concept but mapping and ablation performed with a manually controlled steerable sheath. One hundred sixty‐six patients were selected to be included into 83 matched patient pairs. Ablation success was measured with serial 7‐day Holter electrocardiograms. Patients ablated with the steerable sheath showed an increase in the success rate (freedom from AF) from 56% to 77% (P = 0.009) after a single procedure and 6 months of follow‐up. With respect to procedural data no difference could be found for procedure time, fluoroscopy time, irradiation dose, and radiofrequency (RF) burning time. With the steerable sheath mean procedural RF power (33 ± 9 vs 41 ± 4 W; P < 0.0005) and total RF energy delivery (97,498 vs 111,864 J; P < 0.005) were significantly lower and the rate of complete PV isolation significantly increased from 10% to 52% (P < 0.0005). The complication rate was the same in both groups. Among different arrhythmia, procedure, and patient characteristics, the lack of early postinterventional arrhythmia recurrences was the only but powerful predictor for long‐term ablation success.
Conclusions: An AF mapping and ablation approach solely using a manually controlled steerable sheath for catheter navigation improved the outcome of circumferential left atrial PV ablation at similar intervention times and similar complication rates. The 6‐month success rate after a single LA intervention increased from 56% to 77%.

Background: As bariatric surgery has become an increasingly popular treatment for obesity, we have seen an increasing number of patients present after bariatric surgery with new‐onset syncope, near‐syncope, and lightheadedness.
Methods: We retrospectively reviewed patients who had had bariatric surgery referred to our institution for evaluation of orthostatic intolerance. We reviewed history, physical examination, type of bariatric surgery procedure, and tilt table test results in these patients. There were 14 women and one man with mean age 42 ± 6 years, preoperative body mass index was 49.3 ± 6.0 kg/m2, and mean postoperative weight loss was 55.9 kg. Mean onset of symptoms was 5.2 ± 3.9 months after surgery. Presenting symptoms were lightheadedness in 15 (100%), near‐syncope in 11 (73%), and syncope in nine (60%). All but one patient had a positive tilt table test with eight (53%) having a neurocardiogenic response, three (20%) having a dysautonomic response, and (20%) having a postural tachycardia response. The likely mechanism of orthostatic intolerance is autonomic insufficiency in combination with reverse course of obesity‐related hypertension. The majority of the patients (12 out of 15) responded to standard therapy for autonomic insufficiency.
Conclusion: Some patients may develop significant orthostatic intolerance due to autonomic insufficiency following bariatric surgery, and awareness of the potential association between bariatric surgery and new orthostatic intolerance is important for providing timely care.
Remote Magnetic Navigation‐Assisted Catheter Ablation Enhances Catheter Stability and Ablation Success with Lower Catheter Temperatures
Authors: DAVIS DARRYL R. , TANG ANTHONY S.L. , GOLLOB MICHAEL H. , LEMERY ROBERT , GREEN MARTIN S. , BIRNIE DAVID H. 
Published: July 2008

Background: It has been suggested that remote magnetic navigation (RMN) may provide enhanced catheter stability and substrate contact to aid in ablation. To date, no study has examined this claim. Accordingly, we compared the characteristics of the successful ablation of atrioventricular reentry tachycardia (AVNRT) using RMN with a matched population ablated using a conventional (CON) manual approach.
Methods: Sixteen patients who underwent RMN‐assisted ablation of typical AVNRT were matched with 16 patients who had a CON‐AVNRT ablation.
Results: All patients had successful slow pathway modification without complication. The mean catheter temperature achieved with the successful ablation was significantly lower with RMN than with CON (42 ± 7°C vs 47 ± 3°C, P ≤ 0.05). Time to junctional tachycardia (JT) was significantly earlier (5.7 ± 4.1 s vs 11.2 ± 8.9 s, P ≤ 0.05) and variation in catheter temperature with the successful ablation (0.89 ± 0.45 vs 1.45 ± 0.49, P < 0.01) was significantly reduced in the RMN group than in the CON group. There was no significant difference between RMN and CON in terms of the total number of lesions and the mean power achieved during the successful lesion.
Conclusions: Although the construction of the ablation catheters is similar, ablations with RMN catheters resulted in a lower mean temperature, earlier time to JT, and less variability of temperature during ablation, suggesting greater catheter stability. This study indicates that ablation with RMN can achieve success with lower catheter temperatures.

Published: July 2008

Introduction: Mapping of intraatrial reentrant tachycardia (IART) still presents a challenge in complex congenital heart disease. The goal of this work was to present our initial experience with remote magnetic navigation (RMN) for mapping of IART in four patients after the atrial switch procedure (Mustard n = 1, Senning n = 3) for d‐transposition of the great arteries. Methods: Three‐dimensional (3D) mapping of the systemic venous atrium and the pulmonary venous atrium (PVA) was performed using RMN (Niobe) in conjunction with 3D mapping (CartoRMT). The maps were fused with a CT‐based 3D anatomy. Results: All patients had cavotricuspid isthmus‐dependent IART with a mean atrial cycle length of 305 ms. Mapping of both atria (PVA retrogradely by passing the aortic and tricuspid valve) was feasible and safe. The procedure time for IART mapping ranged from 210 to 320 minutes with a mean of 251 minutes. The fluoroscopy time for IART mapping ranged from 15.8 to 45.0 minutes (mean 31.6 minutes) for patients, and ranged from 12.3 to 24.3 minutes with a mean of 19.5 minutes for physicians. No procedural complications occurred. Conclusion: Precise mapping of IART in the complex anatomical structures after an atrial switch procedure was feasible and safe using RMN. The maneuverability of the catheter was possible even with a retrograde access crossing two valves. Further reduction of procedural and fluoroscopy times for both patients and physicians seems possible

Background: It is unknown whether abnormal heart rate turbulence (HRT) and abnormal fractal properties of heart rate variability identify older adults at increased risk of cardiovascular death (CVdth). Methods: Data from 1,172 community‐dwelling adults, ages 72 ± 5 (65–93) years, who participated in the Cardiovascular Health Study (CHS), a study of risk factors for CV disease in people ≥65 years. HRT and the short‐term fractal scaling exponent (DFA1) derived from 24‐hour Holter recordings. HRT categorized as: normal (turbulence slope [TS] and turbulence onset [TO] normal) or abnormal (TS and/or TO abnormal). DFA1 categorized as low (≤1) or high (>1). Cox regression analyses stratified by Framingham Risk Score (FRS) strata (low = <10, mid = 10–20, and high >20) and adjusted for prevalent clinical cardiovascular disease (CVD), diabetes, and quartiles of ventricular premature beat counts (VPCs). Results: CVdths (N = 172) occurred over a median follow‐up of 12.3 years. Within each FRS stratum, low DFA1 + abnormal HRT predicted risk of CVdth (RR = 7.7 for low FRS; 3.6, mid FRS; 2.8, high FRS). Among high FRS stratum participants, low DFA1 alone also predicted CVdth (RR = 2.0). VPCs in the highest quartile predicted CVdth, but only in the high FRS group. Clinical CV disease predicted CVdth at each FRS stratum (RR = 2.9, low; 2.6, mid; and 1.9, high). Diabetes predicted CVdth in the highest FRS group only (RR = 2.2). Conclusions: The combination of low DFA1 + abnormal HRT is a strong risk factor for CVdth among older adults even after adjustment for conventional CVD risk measures and the presence of CVD.
The Political Impact of Labor Migration in Bahrain
Authors: LOUËR LAURENCE 
Published: July 2008

AbstractThis paper shows that, in Bahrain, the main political consequence of migration has been the deepening of state/society conflict. While having old historical roots, this conflict has been fostered in the recent period by the collapse of the “caste system” that, since the 1970s, used to regulate the relations between foreigners and nationals in the labor market by preventing the two groups from being in competition for jobs. I conclude that in order to evaluate the possible political impact of migration in the Gulf States, one has to look first at the structure of the relation between the national population and the migrants, rather than focus on the number of foreigners.
Fluid City, Solid State: Urban Environmental Territory in a State of Emergency, Kathmandu
Authors: RADEMACHER ANNE M. 
Published: July 2008

AbstractThis paper addresses the relationship between contemporary territorial processes of statemaking and the fluidity associated with globalizing cities. Focused on the remaking of urban environmental space during a period of political emergency in Kathmandu, the paper examines how state power was sustained and articulated through the production of urban environmental forms, and shows how particular modes of violence and governance were enabled in urban environmental territory. Through an analysis of beautification initiatives undertaken in concert with preparations for a major regional trade conference, I argue that urban environmental productions are critical for understanding the semiotics, multiple scales, and materialities of statemaking in twenty‐first century cities.
A Matter of “Co‐opportunism”: (In)Alienability in London Social Housing
Authors: LAVIOLETTE PATRICK 
Published: July 2008

AbstractThis paper explores the dynamics of temporary urban residency. It looks at the relationships between domesticity, mobility and improvisational housing – all relevant to Britain's housing crisis. Hence, I offer a reflexive ethnographic description of ‘short‐life’ co‐op living based on a five year account of managing vacant properties that await refurbishment or re‐development by two major Charitable Housing Trusts based in West London. In questioning how tenants deal with the constant threat of having to move, I ask how members of a short‐life housing co‐op create their own sense of self and stability through a temporary form of accommodation. My goal is thus to investigate how these co‐op tenants appropriate space, relocate themselves and cope with transient domestic alienability. The creative formulation of individual and community identities are central to the wider understanding and implications of residential instability, alternative lifestyles and the general underlying ethos of co‐operative organizations.
The 3‐Minute Emergency Medicine Medical Student Presentation: A Variation on a Theme
Authors: Davenport Chip , Honigman Benjamin , Druck Jeff 
Published: July 2008

AbstractOral presentations are a critical element in the communication of medical knowledge between students and faculty, but in most locations, the amount of time spent on teaching the oral presentation is minimal. Furthermore, the standard oral presentation does not work well within the emergency medicine (EM) setting, due to time constraints and the different principles that make EM a unique specialty. This article provides a suggested approach on how to educate students on optimal oral presentations in EM, as well as providing a link to an online guide instructing medical students how to give oral presentations.ACADEMIC EMERGENCY MEDICINE 2008; 15:683–687 © 2008 by the Society for Academic Emergency Medicine
