Minimally invasive periareolar approach to repair sinus venosus atrial septal defect with partial anomalous pulmonary venous connection.

BACKGROUND AND AIM: Atrial septal defects with anomalous venous connections are commonly repaired via sternotomy, requiring careful baffle reconstruction to redirect pulmonary venous return and ensure a durable result. The cosmetically appealing periareolar incision may provide an esthetically superior alternative to the anterolateral minithoracotomy incision used in minimally invasive cardiac surgery. METHODS: We describe a patient with a sinus venosus atrial septal defect and partial anomalous pulmonary venous connection who underwent successful minimally invasive, endoscopic repair with apical vein translocation and autologous pericardial baffle reconstruction through a periareolar approach. RESULTS: Post-operative echocardiography demonstrated excellent results with no residual shunt and a widely patent baffle and preserved biventricular function. At 1-year post-op, our patient has had a greatly improved quality of life and an excellent cosmetic result with normal nipple-areolar sensation. CONCLUSIONS: We believe that periareolar approaches should be considered for all adult patients with simple and complex atrial septal defects.

Thromboprophylaxis With Heparin During Orthotopic Liver Transplantation: Comparison of Hepcon HMS Plus and Anti-Xa Assays for Low-Range Heparin.

OBJECTIVES: The purpose of this study was to compare the agreement between two heparin assays, Hepcon HMS plus/Kaolin-ACT and Anti-Xa, and their predictive power in detecting circulating heparin levels post-reperfusion of the liver graft when compared with thromboelastogram (TEG) r time ratio in patients undergoing orthotopic liver transplantation (OLT). DESIGN: Prospective, observational cohort study design. SETTING: Single center, university hospital. PARTICIPANTS: Thirty-eight consecutive adults who had undergone liver transplant. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Paired arterial blood samples were collected before surgical incision, 5 minutes after administration of an average dose of 2,054±771 units of intravenous unfractionated heparin before caval cross-clamping, 5 minutes after portal reperfusion, 5 minutes after hepatic artery reperfusion, and 1 hour after hepatic artery reperfusion. The observations that heparin assay measurements were within the predetermined limits of agreement, strongly suggested the two heparin assays (Hepcon HMS plus and Anti-Xa assay) are interchangeable during prophylactic heparin dose therapy during OLT. Post-reperfusion, receiver operating characteristic curve analysis revealed high accuracy in measuring circulating heparin levels with both Anti-Xa and Hepcon HMS assays when compared with the TEG r time ratio assay. CONCLUSIONS: The point-of-care Hepcon HMS plus/Kaolin-ACT (activated clotting time) assay appeared to be a reliable alternative to the more expensive and laboratory-required Anti-Xa assay in monitoring the response to intravenous heparin in patients undergoing OLT.

A randomized trial of nicotine enemas for active ulcerative colitis.

BACKGROUND & AIMS: Ulcerative colitis (UC) is largely a disease of nonsmokers in which transdermal nicotine improves the symptoms but often causes adverse events (AEs). Nicotine enemas cause fewer AEs and were used as supplemental treatment for active UC. METHODS: We treated 104 patients with active UC with either 6-mg nicotine enemas or placebo enemas for 6 weeks in a randomized double-blind study. Patients continued their oral therapy, if any, for UC: 68 patients were taking mesalamine, 15 patients were taking prednisolone, and 12 patients were taking thiopurines during the study. Clinical, sigmoidoscopic, and histologic assessments were made at baseline and at the end of the study and symptoms were recorded daily on a diary card. The primary end point was induction of clinical remission and clinical improvement also was measured by the UC disease activity index. After the study, patients then used nicotine enemas daily for 4 weeks and sigmoidoscopy with a biopsy examination was repeated. AEs and salivary cotinine levels were monitored throughout the study. RESULTS: Clinical remission was achieved in 14 of 52 (27%) patients on active treatment and 14 of 43 (33%) patients on placebo (P = .55). The UC disease activity index improved by 1.45 points in the active group and by 1.65 points for those on placebo (P = .88). Only 1 patient discontinued treatment because of an AE (abdominal pain). In the 47 patients taking mesalamine only, active treatment conferred benefit that was not statistically significant; disease remission occurred in 9 of 25 patients on active therapy and 4 of 21 patients on placebo (P = .20). CONCLUSIONS: Six-milligram nicotine enemas were well tolerated but were not found to be efficacious for active UC.

Supplement use among men with prostate cancer.

OBJECTIVES: To characterize supplement use within a sample population of men diagnosed with prostate cancer. METHODS: A census of men diagnosed with prostate cancer at Duke University Medical Center from 1997 to 2002 (n = 1402) was mailed a survey that ascertained data on health status, education, diet, exercise, smoking status, and information on supplement use. Differences between demographic and treatment subgroups were described and tested, as was change in supplement use after diagnosis. RESULTS: Data from 805 respondents indicated that a majority (73%) used supplements, and 68% claimed that this information was shared with their cancer care provider. The most commonly reported supplements were multivitamins (56%), vitamin E (43%), vitamin C (33%), and calcium (26%). On average, 2.7 +/- 2.8 supplements per day were taken, and use increased significantly after diagnosis for most supplements. Use was significantly higher among men who were white (P = 0.043), were more highly educated (P = 0.002), exercise regularly (P = 0.020), and who consume five or more daily servings of fruits and vegetables (P = 0.040). CONCLUSIONS: A high percentage of men with prostate cancer take supplements, especially those who are white, more educated, and who pursue healthful behaviors. Systematic means of capturing these data are necessary to begin to understand the potential impact of supplements on disease outcome, especially because no data exist to suggest that supplements are of any benefit after diagnosis.
