                     href="http://www.medpagetoday.com/Washington-Watch/Washington-Watch/tb/18388?impressionId=1265771655655"
                     
      &lt;p&gt;Representative John P. Murtha (D-Pa.), 77, long-time chairman of the House Appropriations Subcommittee on Defense, died yesterday afternoon from complications following a planned laparoscopic cholecystectomy, according to a statement from the congressman&apos;s office.&lt;/p&gt;
&lt;p&gt;He had been admitted to the intensive care unit at Virginia Hospital Center in Arlington on Jan. 31, days after surgeons at the National Naval Medical Center in Bethesda, Md., accidentally nicked his intestine during the operation, according to a report in &lt;em&gt;The Washington Post&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;In that same report, Rep. Bob Brady (D-Pa.), a close friend of Murtha&apos;s, said the congressman developed an infection and fever.&lt;/p&gt;
&lt;p&gt;Citing a request for privacy from the Murtha family and patient privacy laws, a spokesperson for the National Naval Medical Center declined to provide information on the operation.&lt;/p&gt;
&lt;p&gt;In a statement, Virginia Hospital Center said Murtha died &quot;despite aggressive critical care interventions.&quot;&lt;/p&gt;


  &lt;p&gt;Mark Malangoni, MD, surgeon-in-chief at MetroHealth Medical Center in Cleveland, told &lt;em&gt;MedPage Today&lt;/em&gt; that serious complications, including bowel damage and death, are not common following cholecystectomy. More complicated patients, such as the obese and diabetics, have a greater risk of complications and of a switch to an open procedure.&lt;/p&gt;
    &lt;p&gt;Death is extremely rare in healthy individuals, occurring in no more than one per 1,000 patients, according to the American College of Surgeons (ACS).
    &lt;p&gt;More common, but still infrequent, are bleeding and leakage of bile, both of which can be treated fairly easily, said Malangoni, a regent of the ACS.&lt;/p&gt;


&lt;p&gt;When the bowel is damaged, as reportedly occurred in Murtha&apos;s case, it typically occurs in two ways -- either from a sharp injury when the trocars used for a laparoscopic procedure are inserted or from a cautery burn.
    &lt;p&gt;Both types of injury can go unnoticed by the surgeon and may not become apparent for days after the operation, Malangoni said.&lt;p&gt;
    &lt;p&gt;Although he did not know the details of Murtha&apos;s case, Malangoni said a patient would usually be admitted right away, at least overnight, if the surgeon realized that an injury had occurred. The procedure likely would have switched from a laparoscopic one to an open one as well.&lt;/p&gt;


&lt;p&gt;A 2009 Cochrane Review comparing laparoscopic versus open cholecystectomy for patients with symptomatic cholecystolithiasis found no difference in mortality in 38 trials. No patients died in the laparoscopic group and only 0.09% died in the open group.&lt;/p&gt;
&lt;p&gt;Severe complications were reported in 2.2% of the laparoscopic patients and 6.8% of the open patients.&lt;/p&gt;


 &lt;p&gt;Malangoni said most surgeons become experienced with performing laparoscopic cholecystectomies before completing their residency; most will perform 40 or 50 by the end of training.&lt;p&gt;
    &lt;p&gt;&quot;It is a very common operation, so once out into practice, most general surgeons are doing dozens of these each year,&quot; he said. &quot;So your experience comes about pretty quickly.&quot;
    &lt;p&gt;It is unclear how much experience Murtha&apos;s surgeon had.&lt;/p&gt;

&lt;p&gt;Murtha had recently become the longest serving member of Congress in Pennsylvania state history.&lt;/p&gt;
&lt;p&gt;First elected in 1974, Murtha, a former Marine, was the first Vietnam War combat veteran to serve in Congress, and he served as an advocate for the military throughout his career. He was also a prominent critic of the Iraq War.&lt;/p&gt;
&lt;p&gt;Murtha is survived by his wife, Joyce, and three children.&lt;/p&gt;

                     score="0.007"
                     href="http://www.medpagetoday.com/Gastroenterology/LiverTransplantation/tb/18203?impressionId=1265771655655"
                     
      &lt;p&gt;Patients who travel to foreign countries for organ transplants may return with more problems than they left with  --  and physicians here have a moral responsibility to treat them, researchers asserted in a transplant journal.&lt;/p&gt;
&lt;p&gt;&quot;Medical tourism&quot; has been on the rise as demand for organs outpaces supply and U.S. healthcare costs skyrocket, Thomas D. Schiano, MD, and Rosamond Rhodes, PhD, of Mount Sinai School of Medicine, reported in &lt;em&gt;Liver Transplantation&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;Researchers have estimated that 300 medical tourism transplants occurred between 2004 and 2006, with more than 40% of transplant tourists residing in New York or California, which have only 18% of the total U.S. population. (See &lt;a href=&quot;http://www.medpagetoday.com/PublicHealthPolicy/HealthPolicy/12564&quot; mce_href=&quot;http://www.medpagetoday.com/PublicHealthPolicy/HealthPolicy/12564&quot; target=&quot;_blank&quot;&gt;International Medical Trade Turns Big Business&lt;/a&gt;)&lt;/p&gt;
&lt;p&gt;Yet physicians have had little guidance on delivering care to these patients, and some transplant centers may turn them away, based on their actions, Schiano and Rhodes wrote.&lt;/p&gt;
&lt;p&gt;Their questions about treatment arose with a 46-year-old Chinese patient who had been put on a waiting list for a liver transplant here because of end-stage liver disease.&lt;/p&gt;
&lt;p&gt;The patient waited on the list for a year as his disease progressed from 18 points to 21 points on a 40-point severity scale.&lt;/p&gt;
&lt;p&gt;Rather than wait any longer, the patient flew to China and had a liver transplant there.&lt;/p&gt;
&lt;p&gt;Many transplanted organs in China come from executed prisoners, raising concerns about disease. Also, foreign transplants may be compromised by poor organ matching, unhealthy donors, and post-transplant infections, while some transplant centers abroad may use substandard surgical techniques, the researchers said.&lt;/p&gt;
&lt;p&gt;Foreign centers are also less likely to send patients home with adequate records and education than centers here, they asserted.&lt;/p&gt;
&lt;p&gt;Three months after his transplant in China, the patient came back to the clinic at Mount Sinai for follow-up care because he was about to run out of imunosuppressive medication.&lt;/p&gt;
&lt;p&gt;Two months after that, the patient developed sepsis due to diffuse intrahepatic biliary stricturing related to hepatic artery thrombosis.&lt;/p&gt;
&lt;p&gt;He required three additional hospitalizations for biliary sepsis, and at that point, retransplantation was the only viable option, Schiano said.&lt;/p&gt;
&lt;p&gt;However, members of the medical team had conflicting views about giving the patient another new liver.&lt;/p&gt;
&lt;p&gt;&quot;He was a medically suitable candidate,&quot; Schiano and Rhodes wrote, &quot;but there was disagreement about whether it was morally right to provide him with a transplant.&quot;&lt;/p&gt;
&lt;p&gt;The clinicians had few ethical guidelines to refer to in making their decision because many deal solely with moral issues related to donors and foreign medical standards.&lt;/p&gt;
&lt;p&gt;For example, the International Society for Heart and Lung Transplantation issued a statement against accepting organs from prisoners in April 2007, and the American Association for the Study of Liver Diseases and the International Liver Transplant Society endorsed similar policies.&lt;/p&gt;
&lt;p&gt;The American Medical Association&apos;s guidelines on medical tourism focus on best practices  --  for example, the procedure must be voluntary, it can&apos;t limit the alternatives offered to patients, and patients should only be referred to accredited institutions.&lt;/p&gt;
&lt;p&gt;While the United Network for Organ Sharing (UNOS)&apos;s statement on medical tourism does maintain that the medical community has an obligation to provide care for these patients, it stops short of offering further direction to transplant programs.&lt;/p&gt;
&lt;p&gt;&quot;Little guidance is provided for dealing with the specific problems of patients who choose to become transplant tourists,&quot; Schiano and Rhodes wrote.&lt;/p&gt;
&lt;p&gt;Instead, they created some ethical guidance for the &quot;moral quandary.&quot;&lt;/p&gt;
&lt;p&gt;Physicians have a &quot;professional obligation to promote the good of patients&quot; as well as a &quot;professional responsibility to adhere to medicine&apos;s commitment to nonjudgmental regard,&quot; they wrote.&lt;/p&gt;
&lt;p&gt;&quot;Taken together, the moral principles of beneficence and nonjudgmental regard direct us to treat potential or returning transplant tourists as we would treat other patients under our care by focusing on providing the medical treatment and support they need,&quot; they continued.&lt;/p&gt;
&lt;p&gt;Physicians shouldn&apos;t deny patients post-transplantation care, and they ought to provide emergent care at the very least. They may refer the patient to another transplant center for long-term follow-up if they regard it as unethical to continue treatment.&lt;/p&gt;
&lt;p&gt;Patients should also be informed about the possibility of transplant tourism when they are not eligible for a transplant in the U.S. or when they are likely to die before reaching the top of the transplant list, Schiano and Rhodes wrote.&lt;/p&gt;
&lt;p&gt;&quot;Patients should not be threatened with abandonment by a center&apos;s refusal to provide care upon their return,&quot; they added.&lt;/p&gt;
&lt;p&gt;As for the 46-year-old patient who was transplanted in China, the Mount Sinai team decided a transplant program must treat all patients on the basis of their need &quot;regardless of what they might have done or how they secured their transplant organ.&quot;&lt;/p&gt;
&lt;p&gt;&quot;Although [the patient] had a long, complicated transplantation course,&quot; they wrote, &quot;he is currently doing well.&quot;&lt;/p&gt;
&lt;p&gt;Mount Sinai has seen a total of nine patients who pursued transplants in China. Three of those had post-transplant problems but had been turned away elsewhere &quot;because several transplant centers in our region do not render care to transplant tourists,&quot; the authors wrote.&lt;/p&gt;
&lt;p&gt;Seven of those nine patients have hepatitis B. Another three had had a renal transplant in India, and subsequently developed liver failure, the authors reported.&lt;/p&gt;

                     title="Immune Cells Point to Skin Cancer Risk after Transplants (CME/CE)"
                     score="0.007"
                     href="http://www.medpagetoday.com/Nephrology/KidneyTransplantation/tb/18200?impressionId=1265771655655"
                     
      Monitoring two types of immune cells in kidney transplant recipients might identify patients with an increased risk of skin cancer, British investigators reported.&lt;br&gt;
&lt;br&gt;Increased levels of T-regulatory cells (Tregs) more than doubled the risk of squamous cell cancer of the skin. Decreased levels of natural killer (NK) cells were associated with more than a five-fold increased risk of skin cancer.&lt;br&gt;
&lt;br&gt;Both immune parameters had substantially greater predictive power than a history of squamous-cell skin cancer, according to an online report in the &lt;em&gt;Journal of the American Society of Nephrology&lt;/em&gt; by a team of Oxford University investigators.&lt;/p&gt;
&lt;p&gt;&quot;Squamous cell cancer of the skin affects about 30% of kidney transplant patients after 10 years of immunosuppression,&quot; Robert Carroll, MD, currently of Queen Elizabeth Hospital in Woodville, Australia, observed in a statement.&lt;/p&gt;
&lt;p&gt;&quot;A small number of patients develop multiple skin cancers per year, but there is no laboratory test to determine which transplant recipients will develop multiple skin cancers in the future.&quot;&lt;/p&gt;
&lt;p&gt;&quot;If a test can confirm high risk of skin cancer development, this may help clinicians to tailor immunosuppressive regimens for individual patients,&quot; he added.&lt;/p&gt;
&lt;p&gt;Long-term immunosuppression, such as that required for transplant recipients, confers an increased risk of squamous-cell skin cancer.&lt;/p&gt;
&lt;p&gt;Estimates of the magnitude have ranged as high as 200 times greater than the general population, the authors wrote. Additionally, 3% of organ transplant recipients require extensive plastic surgery each year as a result of skin cancer lesions.&lt;/p&gt;
&lt;p&gt;Age at transplantation and the immunosuppression dosage are the principal determinants of skin-cancer risk, and the dosage of immunosuppression also influences the risk of metastasis from squamous-cell cancer of the skin.&lt;/p&gt;
&lt;p&gt;In the general population, cancer has been associated with increased levels of Tregs, including CDR&lt;sup&gt;+&lt;/sup&gt;CD25&lt;sup&gt;high&lt;/sup&gt;FOXP3&lt;sup&gt;+&lt;/sup&gt; and CD8&lt;sup&gt;+&lt;/sup&gt;CD28&lt;sup&gt;-&lt;/sup&gt; cells. The same types of cells could play a role in the risk of skin cancer among organ transplant recipients, the authors wrote.&lt;/p&gt;
&lt;p&gt;Within the tumor microenvironment, Tregs may impair the antitumor activity of CD8&lt;sup&gt;+&lt;/sup&gt; and NK cell. However, in organ transplant recipients, Tregs help control or prevent rejections and may help improve long-term outcomes.&lt;/p&gt;
&lt;p&gt;Different immunosuppressive drugs affect Tregs differently, the authors continued. Sirolimus (Rapamune), for example, increases the number of FOXP3&lt;sup&gt;+&lt;/sup&gt; cells, whereas cyclosporine decreases Treg numbers.&lt;/p&gt;
&lt;p&gt;&quot;Tregs have not been assessed in relation to cancer after transplantation,&quot; the authors wrote. &quot;We therefore investigated the hypothesis that squamous-cell cancer in kidney transplant recipients would be associated with an increased number of Tregs.&quot;&lt;/p&gt;
&lt;p&gt;To examine the hypothesis, investigators phenotyped peripheral blood from 65 kidney transplant recipients with squamous skin cancer and 51 recipients without skin cancer, matched for age, sex, and duration of immunosuppression.&lt;/p&gt;
&lt;p&gt;They also quantified lymphocyte populations in skin cancer lesions from a subset of 25 patients and matched them with 25 other nontransplant patients with squamous cell cancer of the skin.&lt;/p&gt;
&lt;p&gt;The kidney transplant recipients had a median follow-up of 340 days. The investigators found that a concentration of &amp;gt;35 peripheral FOXP3&lt;sup&gt;+&lt;/sup&gt;CD4&lt;sup&gt;+&lt;/sup&gt;CD127&lt;sup&gt;low&lt;/sup&gt; regulatory T cells/&amp;#181;L was associated with a hazard ratio for squamous cell skin cancer of 2.48 (95% CI 1.04 to 5.98).&lt;/p&gt;
&lt;p&gt;An NK cell count &amp;lt;100 cells/&amp;#181;L was associated with a skin cancer hazard ratio of 5.6 (95% CI 1.31 to 24). A history of squamous cell cancer of the skin increased the risk of skin cancer recurrence by a third (HR 1.33, 95% CI 1.15 to 1.53).&lt;/p&gt;
&lt;p&gt;&quot;If similar immune phenotypes are predictive in other kidney transplant recipient populations, then immune phenotype method has the potential to inform immunosuppressive regimen manipulation in kidney transplant recipients at high risk for developing multiple squamous cell cancers,&quot; the authors concluded.&lt;/p&gt;

                     title="Preop CT May Reduce Unnecessary Appendectomy (CME/CE)"
                     score="0.005"
                     href="http://www.medpagetoday.com/Surgery/GeneralSurgery/tb/18185?impressionId=1265771655655"
                     
      Using computed tomography (CT) to diagnose appendicitis may reduce the likelihood of removing healthy organs in women under 45, but not among other groups, a retrospective study showed.&lt;br&gt;
&lt;br&gt;Over a 10-year period, the use of preoperative CT increased from 18.5% of patients who ultimately had their appendices removed to 94.2% (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.00001), according to Courtney Coursey, MD, of Duke University Medical Centeri, and colleagues.&lt;br&gt;
&lt;br&gt;During the same time period, the rate of negative appendectomy (removal of a healthy organ) declined, although the trend was significant only among women 45 and younger (&lt;em&gt;P&lt;/em&gt;=0.0001), the researchers reported in the February issue of &lt;em&gt;Radiology&lt;/em&gt;.&lt;/p&gt;
&lt;p&gt;&quot;We believe our study . . . supports the use of preoperative CT, particularly in the evaluation of women of reproductive age suspected of having acute appendicitis,&quot; they wrote.&lt;/p&gt;
&lt;p&gt;They acknowledged the radiation risk and potential overuse of CT scans, but concluded, &quot;We believe that the risk of unnecessary surgery justifies the use of CT in patients in whom the clinical diagnosis of appendicitis is uncertain.&quot;&lt;/p&gt;
&lt;p&gt;Previous studies looking at the link between the use of preoperative CT and the negative appendectomy rate have yielded mixed results.&lt;/p&gt;
&lt;p&gt;So Coursey and her colleagues looked at the relationship using data from 1998 to 2007 for 925 adult patients who underwent an appendectomy at Duke. Two-thirds had a preoperative CT no more than 48 hours before surgery.&lt;/p&gt;
&lt;p&gt;Although the overall negative appendectomy fell by nearly half during the study (16.7% to 8.7%, &lt;em&gt;P&lt;/em&gt;&amp;lt;0.0001), it was driven almost entirely by a reduction among women 45 and younger (42.9% to 7.1%, &lt;em&gt;P&lt;/em&gt;=0.0001).&lt;/p&gt;
&lt;p&gt;&quot;However, the timing of the decline in negative appendectomy rates for women 45 years and younger could not be proved to be associated with the increase in CT use,&quot; the researchers noted.&lt;/p&gt;
&lt;p&gt;There were no significant trends in older women or in men of any age.&lt;/p&gt;
&lt;p&gt;&quot;The lack of a decline in the negative appendectomy rates for men and women older than 45 years may be a consequence of the initially low rates resulting in low power,&quot; the authors wrote.&lt;/p&gt;
&lt;p&gt;During the study, false-negative CT scans ranged from 0% to 20%, with lower rates in the later years of the study.&lt;/p&gt;
&lt;p&gt;False-positive scans fluctuated between 1.7% to 10%. A drop in rates of false-positive scans was associated with advances in CT technology.&lt;/p&gt;
&lt;p&gt;The researchers noted some limitations of the study, including the retrospective design and the failure to evaluate the effect of CT detector configuration on diagnostic performance.&lt;/p&gt;
&lt;p&gt;In addition, they wrote, the measure of CT use to diagnose appendicitis was biased because the analysis excluded cases in which CT had ruled out appendicitis.&lt;/p&gt;

                     score="0.002"
                     href="http://www.medpagetoday.com/HematologyOncology/ColonCancer/tb/18164?impressionId=1265771655655"
                     
      Patients 65 and older are as suitable as younger individuals for CT colonography, said researchers conducting a large retrospective study.&lt;br&gt;
&lt;br&gt;Advanced neoplasias were detected with CT colonography  --  often called &quot;virtual colonoscopy&quot;  --  in older patients at more than double the rate in the general screening population, reported David H. Kim, MD, of the University of Wisconsin in Madison, Wis., and colleagues in the February issue of &lt;em&gt;Radiology&lt;/em&gt;.&lt;br&gt;
&lt;br&gt;They found that 7.6% of older patients had advanced neoplasias, compared with 3.2% of all patients screened in the university&apos;s clinic (&lt;em&gt;P&lt;/em&gt;&amp;lt;0.001).&lt;/p&gt;
&lt;p&gt;On the basis of this and other findings in 577 individuals 65 and older versus the entire group of 3,120 patients undergoing the procedure, Kim and colleagues concluded that &quot;CT colonography performance is maintained in an older cohort.&quot;&lt;/p&gt;
&lt;p&gt;&quot;Overall, the observations from this clinical experience confirm that CT colonography may be a valuable screening modality in the older population,&quot; they wrote.&lt;/p&gt;
&lt;p&gt;On the other hand, the study did not address several objections raised by the Centers for Medicare and Medicaid Services (CMS) in its decision last year to deny Medicare coverage for the procedure. (See &lt;a href=&quot;http://www.medpagetoday.com/PublicHealthPolicy/Medicare/14186&quot; mce_href=&quot;http://www.medpagetoday.com/PublicHealthPolicy/Medicare/14186&quot; target=&quot;_blank&quot;&gt;Medicare Finalizes Denial of Virtual Colonoscopy Coverage&lt;/a&gt;)&lt;/p&gt;
&lt;p&gt;CMS had pointed to relatively low sensitivity of CT colonography compared with optical colonoscopy in prospective trials, especially for small lesions.&lt;/p&gt;
&lt;p&gt;The agency also determined that CT colonography increased the costs of positive findings, since abnormalities in the CT scans must be confirmed with optical colonoscopy. In addition, CMS said there was no evidence to support claims that the less invasive imaging procedure would be more acceptable to patients and therefore would raise screening rates.&lt;/p&gt;
&lt;p&gt;The data analyzed by Kim and colleagues did not allow for calculations of false-negative rates or predictive values of positive or negative findings. Nor did the researchers report cost information.&lt;/p&gt;
&lt;p&gt;Mean age of their older cohort was 69.2 (SD 3.8). The oldest was 79.&lt;/p&gt;
&lt;p&gt;The researchers reported that 15.3% of the older patients were referred for optical colonoscopy on the basis of the CT results, compared with 7.9% of the overall screening group.&lt;/p&gt;
&lt;p&gt;Less than 4% of positive findings were determined to be false with the optical procedure (3.6% for polyps 6 to 10 mm in diameter, 2.1% for larger lesions).&lt;/p&gt;
&lt;p&gt;Of the 59 advanced neoplasias identified in the older patients, all but three were at least 10 mm in size.&lt;/p&gt;
&lt;p&gt;The scans also suggested abnormalities outside the colon in 89 (15.4%) patients. Of these, 45 received a full workup, which revealed substantial and previously unsuspected diagnoses in 21 cases  -- 18 were vascular aneurysms. The other three included one lung tumor, a femoral hernia, and a malrotation.&lt;/p&gt;
&lt;p&gt;Kim and colleagues reported that no &quot;substantial complications&quot; such as perforations or major hemorrhage occurred in the older patients, either with the CT scan or follow-up colonoscopy.&lt;/p&gt;
&lt;p&gt;They also indicated that the ratio of large to small neoplasias was similar in the older patients compared with their CT screening group as a whole. Histologic and morphologic findings were similar as well.&lt;/p&gt;
&lt;p&gt;The researchers cited the observational nature of the study, in which negative findings were not corroborated with optical colonoscopy, and its restriction to a single center as its main limitations.&lt;/p&gt;
