Silkclasy: A simple way for liver transection during anatomic hepatectomies
Authors: Herman Paulo , Machado Marcel Autran C. , Machado Marcel C.C. 
Published: December 2006

AbstractBackgroundParenchymal transection is the most important step of liver resection, and during this phase, blood loss may lead to morbidity and mortality. Liver parenchyma can be transected by different ways such as finger fracture, clamp crushing, or instrument‐based techniques.MethodsA simple and cost‐efficient method has been developed for liver transection using a technique based on silk crushing of the liver substance.ResultsWe have successfully employed this technique in 278 consecutive liver resections from July 2001 to March 2006. The average duration of hepatic transection varied according to the type of liver resection: 22 min (range 15–42), 19 min (range 11–37), and 12 min (range 7–21) for right hepatectomy, left hepatectomy, and bisegmentectomy 2‐3, respectively. The mean transection speed was 6.9 ± 2.3 cm2/min. Blood transfusions were necessary in 42 patients (15.1%), and there were three operative deaths (1.1%). Morbidity rate was 20.9% (58 patients).ConclusionsThis technique allows a safe and quick liver transection without the use of expensive hemostatic devices, and also precludes the use of inflow occlusion maneuvers. We recommend the use of this technique in centers with low economic resources. J. Surg. Oncol. 2007;95:86–89. © 2006 Wiley‐Liss, Inc.

AbstractBackground and ObjectivesThe aim of this study was to clarify the significance of surgical treatment for recurrent thymic epithelial tumors with reference to the World Health Organization (WHO) histological classification system.PatientsAmong 67 patients with tumor recurrence, 22 underwent a re‐resection. There were 1 patient with a type AB tumor, 5 with type B1 tumors, 10 with type B2 tumors, 5 with type B3 tumors, and 1 with a carcinoma.ResultsThe 10‐year survival rate following the initial resection was 70% in patients who underwent a re‐resection and 35% in those who did not. The average intervals from the initial resection to re‐resection were 10.3, 7.8, 6.0, 2.4, and 2.6 years for patients with type AB, B1, B2, B3 tumors, and carcinoma, respectively. The patient with a type AB tumor was alive at 2.4 years after re‐resection, 12.7 years after the initial resection. The 5‐year survival rates following re‐resection in the patients with type B1, B2, and B3 tumors were 100, 56, and 60, respectively. The patient with a carcinoma died as a result of the tumor 2 years after re‐resection.ConclusionWHO histological classification indicates the outcome of surgical treatment for recurrent thymic epithelial tumors.

AbstractBackgroundIn this non‐randomized study we aimed to assess the efficacy of the addition of low molecular weight heparin (LMWH) to gemcitabine (GEM) plus cisplatinum (CDDP) combination chemotherapy on survival by prevention of thromboembolic complications in patients with advanced pancreatic cancer (APC).Patients and MethodsBetween November 1999 and February 2004, 69 consecutive patients with APC were treated with GEM (800 mg/m2, day 1, day 8) plus CDDP (35 mg/m2, day 1, day 8) every 21 days ±LMWH (nadroparine calcium, 2,850 IU/day until disease progression). Ten out of 35 patients in LMWH group and 10 out of 34 patients in chemotherapy alone group had primary inoperable locally advanced disease and the rest of the patients had metastatic disease.ResultsTotal response rate was 58.8% (11.7% CR) for the patients treated with LMWH and 12.1% for those treated without LMWH (P = 0.0001). LMWH group had a better median time to progression (TTP) and survival when compared to control group (7.3 vs. 4.0 months,P = 0.0001; 13.0 vs. 5.5 months,P = 0.0001). The toxicity was similar and acceptable in both groups.ConclusionAddition of LMWH to GEM plus CDDP combination significantly improved the response and survival in patients with APC and the current schedule deserves to be tested in phase III trials.

Clear cell sarcoma of soft tissues
Authors: Malchau Sara Sofia , Hayden James , Hornicek Francis , Mankin Henry J. 
Published: December 2006

AbstractClear cell sarcoma (CCS) is a rare but highly malignant tumor of soft tissues often appearing as a small tender mass in the deep tissues of the distal extremities. We have studied 17 patients with such lesions treated since 1986 and have a high incidence of local recurrence and metastasis with a survival rate of only 47% despite surgery and for many of the patients, adjuvant therapy. The purpose of this article is to warn the readers of the dangers related to treating this seemingly benign lesion and urge them to perform wide surgery and utilize adjuvant therapy. J. Surg.

Published: December 2006

AbstractBackground and ObjectivesThe aim of this study was to investigate whether microscopic positive margins are detrimental to the outcome of gastric cancer patients treated with extended (D2/3) gastrectomy.MethodsAmong 2,740 consecutive patients who had undergone extended gastrectomy for advanced gastric cancer between January 1987 and December 2002, 49 patients (1.8%) had positive resection margins on final histology.ResultsAmong 49 patients, 29 (59.2%) had proximal involved margins and 20 (40.8%) had distal involved margins. The median survival time of the positive margin group was 34 months. The negative margin group had a significantly longer median survival time of 69 months (P = 0.025). When both groups of patients were stratified according to nodal stage, a positive resection margin determined a worse prognosis only in patients with node‐negative disease (174 months vs. 37 months, P = 0.0001). In patients with nodal metastasis, the median survival time was similar in both groups.ConclusionsOur results suggest that a positive microscopic margin is associated with a worse outcome in patients with node‐negative disease. Therefore, a more aggressive treatment, such as re‐operation, is needed in node‐negative patients with a positive microscopic disease. J. Surg. Oncol. 2007; 95: 461–468. © 2006 Wiley‐Liss, Inc.
Verbal and physical aggression in World War II former prisoners of war: Role of posttraumatic stress disorder and depression
Authors: O'Donnell Casey , Cook Joan M. , Thompson Richard , Riley Kevin , Neria Yuval 
Published: December 2006

AbstractThis study examined the relationship among posttraumatic stress disorder (PTSD), depression, and intimate partner relationship aggression in a community sample of World War II (WWII) male military former prisoners of war (POWs). Sixty percent of these POWs reported verbal aggression in their marriages, and 12% endorsed physical aggression. Both verbal and physical aggression were significantly correlated to the severity of captivity trauma and to PTSD symptoms. Posttraumatic stress disorder symptoms significantly mediated the relationship between severity of trauma and both verbal and physical aggression. Depression was a significant moderator of the relationship between PTSD and both physical and verbal aggression. Theoretical and clinical implications are suggested.
Changes in coping strategies, relationship to the perpetrator, and posttraumatic distress in female crime victims
Authors: Gutner Cassidy A. , Rizvi Shireen L. , Monson Candice M. , Resick Patricia A. 
Published: December 2006

AbstractThis study examined the relationship between changes in coping and posttraumatic stress disorder (PTSD) symptomatology among recent female rape and physical assault victims as a function of assault type and perpetrator status. Participants were assessed within 1 month after trauma and again at 3 months after trauma. Results indicate that changes in coping strategies over time are associated with the severity of the PTSD symptoms. Assault type was not a significant factor in the association between changes in coping and PTSD, but perpetrator status was. Victims with known perpetrators, who coped more by social withdrawal, had more severe PTSD symptoms over time. The importance of examining the dynamic nature of coping in the development of PTSD is discussed.
Cumulative interpersonal traumas and social support as risk and resiliency factors in predicting PTSD and depression among inner‐city women
Authors: Schumm Jeremiah A. , Briggs‐Phillips Melissa , Hobfoll Stevan E. 
Published: December 2006

AbstractThis study represents one of the largest examinations of how child abuse, adult rape, and social support impact inner‐city women (N = 777). Using retrospective self‐report, the effects of interpersonal trauma were shown to be cumulative such that women who experienced either child abuse or adult rape were 6 times more likely to have probable posttraumatic stress disorder (PTSD), whereas women who experienced both child abuse and rape were 17 times more likely to have probable PTSD. High social support predicted lower PTSD severity for women who experienced both child abuse and adult rape, but not for women who reported one or none of these traumas. Results suggest that social support, when left intact, might buffer the cumulative impact of child and adult interpersonal traumas.
Is mixed‐handedness a marker of treatment response in posttraumatic stress disorder?: A pilot study
Authors: Forbes David , Carty Jessica , Elliott Peter , Creamer Mark , McHugh Tony , Hopwood Malcolm , Chemtob Claude M. 
Published: December 2006

AbstractRecent studies suggest that mixed‐handedness is a risk factor for posttraumatic stress disorder (PTSD). This study examined whether mixed‐handed veterans with combat‐related PTSD respond more poorly to psychosocial treatment. Consistency of hand preference was assessed in 150 Vietnam combat veterans with PTSD using the Edinburgh Handedness Inventory (R. C. Oldfield, 1971). Growth modeling analyses using Mplus (L. K. Muthén & B. Muthén, 2002) identified that PTSD veterans with mixed‐handedness reported significantly less treatment improvement on the PTSD Checklist (F. W. Weathers, B. T. Litz, D. S. Herman, J. A. Huska, & T. M. Keane, 1993) than did veterans with consistent handedness. These data suggest that mixed‐handedness is associated with poorer PTSD treatment response. Several possible explanations for this finding are discussed.
University of Rhode Island Change Assessment–Trauma: Preliminary psychometric properties in an alcohol‐dependent PTSD sample
Authors: Hunt Yvonne M. , Kyle Tiffany L. , Coffey Scott F. , Stasiewicz Paul R. , Schumacher Julie A. 
Published: December 2006

AbstractThe co‐occurrence of posttraumatic stress disorder with substance use disorders (PTSD‐SUD) is common and is associated with poorer treatment outcomes. Attrition represents an ongoing, but poorly understood challenge in PTSD‐SUD treatment research. The current study examined the initial psychometric properties of the University of Rhode Island Change Assessment—Trauma (URICA‐T), a scale designed to assess attitudes and behaviors related to addressing trauma issues, in a sample of 42 individuals meeting diagnostic criteria for PTSD and alcohol dependence. Results suggest that the URICA‐T may have acceptable psychometric properties as a continuous measure of motivational readiness in a PTSD‐SUD sample. Preliminary data also suggests higher URICA‐T scores are associated with retention of alcohol dependent‐PTSD participants in a study utilizing trauma‐focused exposure.
Posttraumatic stress disorder and treatment seeking in a nationally representative Canadian military sample
Authors: Fikretoglu Deniz , Brunet Alain , Schmitz Norbert , Guay Stephane , Pedlar David 
Published: December 2006

AbstractThis study aimed to identify predictors of treatment seeking in military members with posttraumatic stress disorder (PTSD) using data from the 2002 Canadian Community Health Survey–Canadian Forces Supplement (Statistics Canada, 2003). To identify predictors, two complementary analyses (binary logistic regression and recursive partitioning of independent variables) were conducted in military members with PTSD (N = 509). Results indicate that trauma‐related (index traumatic event type, cumulative trauma exposure), demographic (marital status), enabling (income), and need (PTSD interference) factors predict treatment seeking in military members with PTSD, and that treatment seekers and nontreatment seekers are both comprised of distinct subgroups. Interventions aimed at increasing treatment‐seeking behaviors should be tailored to the specific needs of various subgroups of nontreatment seekers.
The impact of resource loss and traumatic growth on probable PTSD and depression following terrorist attacks
Authors: Hobfoll Stevan E. , Tracy Melissa , Galea Sandro 
Published: December 2006

AbstractThe authors interviewed by phone 2,752 randomly selected individuals in New York City within 6 to 9 months after the attacks of September 11, 2001 on the World Trade Center, and 1,939 of these were reinterviewed at a 12‐ to 16‐month follow‐up. It was hypothesized that resource loss would significantly predict probable posttraumatic stress disorder (PTSD) and probable depression since September 11, and that resource loss's impact would be independent of previously identified predictors relating to individuals' demographic characteristics, history of stressful event exposure, prior trauma history, peritraumatic experience, and social support. Second, it was predicted that reported traumatic growth would be related to greater, not lesser, psychological distress. The authors' findings supported their hypotheses for resource loss, but traumatic growth was unrelated to psychological outcomes when other predictors were controlled.
The association between childhood abuse, PTSD, and the occurrence of adult health problems: Moderation via current life stress
Authors: Cromer Kiara R. , Sachs‐Ericsson Natalie 
Published: December 2006

AbstractThe association between childhood abuse, current life stressors, and the occurrence of adult medical problems was investigated in the National Comorbidity Survey. It was found that after controlling for a number of covariates, current life stressors moderated the relationship between abuse history and medical problems such that health problems were greater for individuals who had been abused in the presence of current stressors. The findings suggest that a history of childhood abuse, even without the presence of posttraumatic stress disorder (PTSD), can influence the occurrence of poor health if current life stressors are present. Future directions and implications are discussed.
Positive and negative adjustment and social support of sexual assault survivors
Authors: Borja Susan E. , Callahan Jennifer L. , Long Patricia J. 
Published: December 2006

AbstractThe roles of positive (i.e., growth) and negative (i.e., posttraumatic stress symptoms and general symptomatology) adjustment following adult sexual assault experience(s) were examined using a standardized definition of abuse. These reactions were explored in association with positive and negative support from formal and informal providers. Finally, using standardized measures, the collective impact of positive and negative support, formal and informal support were investigated in predicting positive and negative psychological adjustment. Both forms of informal support were found to be associated with positive outcomes. Only negative informal support was associated with posttraumatic stress symptoms. First responders should consider whether support resources are appropriate to victims' needs.
Correlates of posttraumatic growth in survivors of intimate partner violence
Authors: Cobb Amanda R. , Tedeschi Richard G. , Calhoun Lawrence G. , Cann Arnie 
Published: December 2006

AbstractThe negative consequences of intimate partner violence are well documented. This study investigated the possibility that some survivors of intimate partner violence may also experience posttraumatic growth because of their struggle with this highly stressful circumstance. In addition, the relationships between posttraumatic growth and relationship status, type of abuse, depression, and availability of models of posttraumatic growth were examined. Most women reported posttraumatic growth. Overall abuse experienced and depression were unrelated to posttraumatic growth, but abuse was related to one domain of growth. Contact with a model of posttraumatic growth and having left an abusive relationship were both positively related to posttraumatic growth.
El Salvador earthquakes: Relationships among acute stress disorder symptoms, depression, traumatic event exposure, and resource loss

Published: December 2006

AbstractFour and seven weeks after powerful earthquakes in El Salvador, the authors examined the relationships among demographics, traumatic event exposure, social support, resource loss, acute stress disorder (ASD) symptoms, depression, and posttraumatic growth. Participants were 253 college students (Study 1) and 83 people in the community (Study 2). In Study 1, female gender, traumatic event exposure, low social support, and loss of personal characteristic, condition, and energy resources contributed to ASD symptoms and depression. In Study 2, damage to home and loss of personal characteristic and object resources contributed to ASD symptoms and depression. Posttraumatic growth was not associated with ASD symptoms or depression. Findings support the conservation of resources stress theory (Hobfoll, 1998). Resource loss spirals, excessive demands on coping, and exposure to multiple disasters are discussed.
Traumatic events and alcohol use disorders among American Indian adolescents and young adults
Authors: Boyd‐Ball Alison J. , Manson Spero M. , Noonan Carolyn , Beals Janette 
Published: December 2006

AbstractThis study examined the relationship between severe traumatic events and alcohol use disorders in American Indian adolescents and young adults. Interviews of 432 adolescents and young adults who were enrolled tribal members living on or near two closely related American Indian reservations were used. Results indicated that severe trauma increased the odds of alcohol use disorders (p <.001), with the number of traumas having a dose‐dependent effect. The authors conclude that trauma is associated with alcohol use disorders in this population. This study's findings yield important insights into the risks in American Indian adolescents and young adults that may result from early trauma, as well as implications for the timing and possible settings for intervention.

Published: December 2006

AbstractIn a sample of 336 patients with an alcohol use disorder, this study examined, whether patients with histories of childhood sexual abuse (CSA) and childhood physical abuse (CPA) compared to those without such histories have a greater severity of alcohol and other clinical difficulties. Whether lifetime posttraumatic stress disorder (PTSD) mediates the relationship between childhood abuse and clinical outcomes was explored. Results were that CSA was associated with earlier age of onset for alcohol disorder, greater Axis I comorbidity as defined by the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM‐IV; American Psychiatric Association, 1994), more social and psychiatric problems, but lower drinking frequency. Childhood physical abuse was related to greater drinking consequences, social and psychiatric dysfunction, and Axis I comorbidity, but also lower drinking frequency. Posttraumatic stress disorder partially mediated the effect of both CSA and CPA on severity of psychiatric problems.
Posttraumatic stress after a motor vehicle accident: A six‐month follow‐up study utilizing latent growth modeling
Authors: Wu Kitty K. , Cheung Mike W. L. 
Published: December 2006

AbstractFeatures of posttraumatic stress disorder (PTSD) for 596 survivors of motor vehicle accidents were examined by self‐report measures at 1 week, 1 month, 3 months, and 6 months after the motor vehicle accident (MVA). Latent growth modeling was utilized to study the trend and predictors of the level of distress. Results indicated that 5–20% of the participants reported to have a significant level of posttraumatic stress in one, two, or three of the PTSD symptom clusters within the period studied. Survivors with significant acute stress 1 week after the MVA had a higher risk for developing chronic posttraumatic stress. Although the severity of intrusive and hyperarousal symptoms decreased over time, the severity of avoidance symptoms remained unchanged. Factors predicting the course of PTSD after an MVA are identified.
Coping, symptoms, and functioning outcomes of patients with posttraumatic stress disorder
Authors: Tiet Quyen Q. , Rosen Craig , Cavella Steven , Moos Rudolf H. , Finney John W. , Yesavage Jerome 
Published: December 2006

AbstractThis study examines the association between approach coping and better functioning outcomes and the reciprocal relationships between coping and posttraumatic stress disorder (PTSD) symptoms in patients diagnosed with PTSD. Posttraumatic stress disorder patients receiving services in five VA health care systems were randomly selected and surveyed at baseline and followed 10 months later. Analyses of longitudinal data using structural equation modeling techniques showed that more approach coping predicted better family and social functioning. Cognitive avoidance coping predicted more PTSD symptoms, and more PTSD symptoms predicted more approach coping and more behavioral avoidance coping. Approach coping may enable patients with chronic PTSD to establish and maintain better relationships with family and friends, despite continuing PTSD.
Maximizing follow‐up in longitudinal studies of traumatized populations
Authors: Scott Christy K. , Sonis Jeffrey , Creamer Mark , Dennis Michael L. 
Published: December 2006

AbstractAlthough longitudinal research is essential in understanding the nature and course of posttraumatic mental health problems, high rates of attrition often threaten the internal validity of such studies and make results hard to interpret. C. K. Scott (2004) developed an approach to minimizing attrition in longitudinal studies that consistently yielded retention rates in excess of 90% through to 2‐year follow‐up. In this article, the authors discuss the interface between trauma exposure and participation in longitudinal research, before describing in detail a model to address those effects. The effectiveness of the model is examined with reference to traumatic stress in a large community sample (N= 887) with eight waves of data over 2 years.
