Published: November 2013

Abstract
Incidence of triple-negative breast cancer (TNBC), which is cancer without expression of ER, PgR, and HER2, and nuclear grade (NG) are closely correlated with malignant potential of breast cancer. However, criteria to determine aggressiveness of breast cancer based on these factors have not been elucidated. The aim of this study was to create criteria using these factors to predict tumor recurrence in invasive ductal carcinoma (IDC) of the breast. One hundred and seventy-nine patients with IDC of the breast, which had been treated by surgical resection, were included. One point was added for each factor of the two categories of TNBC and NG 3. The sum of the scores (TGS 0, 1, or 2) was calculated. Significant difference was observed between TGS and the incidence of tumor recurrence (P &lt; 0.0001). Moreover, significant differences were observed regarding relapse-free survival (RFS) between patients with TGS 0 and TGS 1 (P &lt; 0.0001) and patients with TGS 1 and TGS 2 (P = 0.024). TGS might contain a clinical advantage as a useful predictor for tumor recurrence of IDC of the breast and could classify prognosis of the patients with a preferable stratification.

Abstract
A 75-year-old woman with a history of myocardial infarction, gallstones, and right renal cancer was referred to our department because of right flank pain. She had a surgical scar on the right abdomen between the 10th and 11th ribs; computed tomography demonstrated intercostal herniation of the colon. Recognizing the possibility of adhesions of the hernia and colon, we used a median skin incision and patched a polyester mesh coated with absorbent collagen. The patient had an uneventful postoperative course, with no pain for 6 months postoperatively. Transdiaphragmatic intercostal hernias with abdominal contents commonly develop after trauma or thoracic surgery. Incisional intercostal hernias seldom develop after nephrectomy; the present case is only the fourth report. We conjecture that a costochondral incision can induce subluxation of the costotransverse joint, intercostal nerve injury, and atrophy of the intercostal and abdominal oblique muscles. Surgeons must therefore recognize the potential, albeit rare, for intercostal hernia after nephrectomy.

Abstract
Several randomized prospective studies in western countries regarding the usefulness of prophylactic drainage have concluded that prophylactic abdominal drainage tubes are unnecessary. In Japan, however, longitudinal and vascular margins are rather different from in western countries. Furthermore, body mass index and volume of mesentery differed. Thus, although it is a retrospective study, it is worth investigating the usefulness of prophylactic drainage in the Japanese context. Two hundred sixty patients underwent colectomy and suprapromontory anastomosis. Prophylactic drainage tubes were inserted in 124 cases (47%) and not inserted in 136 cases (53%). In terms of postoperative complications, no statistically significant difference was found between the with-drainage and the without-drainage groups. The incidence of the abscess formation was not statistically different in the with-drainage group (4.0%) or the without-drainage group (0.7%). We concluded that the prophylactic and informational drainage tubes are not necessary even in Japanese cases of suprapromontory anastomosis, which typically have a wide resection and regional lymphadenectomy containing the roots of regional vessels.

Abstract
We report on a case of ileal lipoma that prolapsed into the ascending colon and was resected by laparoscopy-assisted surgery. A 31-year-old male Japanese patient was admitted to our hospital because of hematochezia and anemia. Colonoscopy revealed a pedunculated polyp arising from the ileum. The surface was covered with slightly edematous mucosa. Abdominal computed tomography showed a low-density mass in the ascending colon. A diagnosis of pedunculated ileal lipoma with intussusception was made, and laparoscopy-assisted surgery was performed. The intussusception was reducted by resection of the lipoma. The surgical specimen was a 40 × 30 × 25 mm round tumor with a long stalk 11 cm in length. Microscopic examination of the specimen revealed ileal lipoma. Laparoscopic surgery is recommended for benign tumors of the small intestine because it is minimally invasive.

Abstract
A 68-year-old man underwent pancreaticoduodenectomy with lymph nodes dissection for carcinoma of the ampulla of Vater. The patient had anxiety neurosis and had been treated with a selective serotonin reuptake inhibitor (SSRI). Postoperatively, SSRI was resumed on postoperative day 2. His serum sodium concentration gradually decreased, and the patient was given a sodium supplement. However, 11 days after the operation, laboratory findings included serum sodium concentration of 117 mEq/L, serum vasopressin of 2.0 pg/mL, plasma osmolality of 238 mOsm/kg, urine osmolality of 645 mOsm/kg, urine sodium concentration of 66 mEq/L, serum creatinine concentration of 0.54 mg/dL, and serum cortisol concentration of 29.1 μg/dL. With a diagnosis of syndrome of inappropriate secretion of antidiuretic hormone (SIADH), the antianxiety neurosis medication was changed from the SSRI to another type of drug. After switching the medication, the patient made a satisfactory recovery with normalization of serum sodium by postoperative day 20.

Abstract
The objective of this study was to analyze the clinical benefit of histopathologic analysis of appendectomy specimens from patients with an initial diagnosis of acute appendicitis. We retrospectively analyzed the demographic and histopathologic data of 1255 patients (712 males, 543 females; age range, 17–85 years) who underwent appendectomy to treat an initial diagnosis of acute appendicitis. Patients who underwent incidental appendectomy during other surgeries were excluded from the study. Histopathologic findings of the appendectomy specimens were used to confirm the initial diagnosis. Ninety-four percent of the appendectomy specimens were positive for appendicitis. Of those, 880 were phlegmonous appendicitis, 148 were gangrenous appendicitis with perforation, and the remaining 88 showed unusual histopathologic findings. In the 88 specimens with unusual pathology, fibrous obliteration was observed in 57 specimens, carcinoid tumor in 11, Encheliophis vermicularis parasite infection in 8, granulatomous inflammation in 6, appendiceal endometriosis in 2, and 1 specimen each showed mucocele, eosinophilic infiltration, Taenia saginata parasite infection, and appendicular diverticulitis. All carcinoid tumors were located in the distal appendix. Six of the 11 carcinoid tumors were defined by histopathology as involving tubular cells, and the other 5 as involving enterochromaffin cells. Six patients had muscularis propria invasion, 2 patients had submucosa invasion, 2 patients had mesoappendix invasion, and 1 patient had serosal invasion. All patients with tumors remained disease free during the follow-up (range, 1–27 months). We conclude that when the ratio of unusual pathologic findings for appendectomy specimens is considered, it is evident that all surgical specimens should be subjected to careful histologic examination.

Gold versus Palladium: A Regioselective Cycloisomerization of Aromatic Enynes

Published: November 2013

AbstractAromatic enynes can be transformed into arylnaphthalenes or benzofulvenes depending on the reaction conditions. Under gold(I) catalysis, exclusive or major 6‐endo‐dig cyclization took place leading to arylnaphthalenes. However, a catalytic system based on palladium iodide/1,3‐bis(diphenylphosphino)propane, in the presence of cesium carbonate as a base was necessary to furnish exclusively 5‐exo‐dig cyclization pattern, regardless of the electronic effects of the substituents. In the latter transformation, a mechanistic study (kinetic isotopic effect, density functional theory) involving a CH activation is suggested for the exclusive formation of benzofulvenes.magnified image
A combined experimental–numerical rheometric and mechanical characterization of EPM/EPDM rubber for medium voltage cable applications vulcanized with peroxides
Authors: Milani Gabriele , Galanti Andrea , Cardelli Camillo , Milani Federico 
Published: November 2013

ABSTRACTThe vulcanization of medium and high voltage (M‐H V) cables is an important industrial application where manufacturers use principally EPM/EPDM, crosslinked polyethylene (XLPE) and now also thermoplastic rubbers. In the present article, an EPDM compound for medium voltage cables—normally distributed to producers in pellets and ready to be cured—is considered and several experimental tests (rheometer curves and mechanical characterizations) are conducted changing controlled curing temperature, peroxide type and peroxide concentration. In particular, tests are replicated in a temperature range between 160 and 200°C, with data provided every 20°C, using two different peroxides, a mixture of three commercial peroxides at five different concentrations. A huge amount of experimental data (cure curves) is obtained (one for each temperature, peroxide used and concentration) and results are critically compared one each other, to have a quantitative insight into the most effective temperature and peroxide to be used during this kind of vulcanization, with the aim of maximizing vulcanization velocity, final torque reached and mechanical properties of cured rubber. The comprehensive experimental study proposed is finally assessed from a numerical point of view, utilizing a complex kinetic scheme constituted by reactions occurring in series and parallel, which allows estimating numerically the vulcanization degree by means of a single second order nonlinear differential equation, with unknown parameters determined through non‐linear least squares fitting, with target data represented by experimental rheoemeter curves. The experimental fitting is almost perfect for all the cases analyzed and is aimed at predicting (without an expensive experimentation) the most suitable production parameters (e.g., curing time and temperature) to guarantee improved mechanical properties and a good aging resistance of the items. In addition, the numerical approach could allow finding the most suitable recipe, also in presence of mixtures of peroxides, able to provide items with a uniform vulcanization level. © 2013 Wiley Periodicals, Inc.

Electrical energy discharging performance of poly(vinylidene fluoride‐co‐trifluoroethylene) by tuning its ferroelectric relaxation with polymethyl methacrylate
Authors: Xia Weimin , Zhang Qiuping , Wang Xiao , Zhang Zhicheng 
Published: November 2013

ABSTRACTPoly(methyl methacrylate) (PMMA) was introduced into ferroelectric Poly(vinylidene fluoride‐co‐trifluoroethylene) P(VDF‐co‐TrFE) via a simple solution blending process and a series of P(VDF‐co‐TrFE)/PMMA blends with varied PMMA content was obtained in an effort to investigate the confinement effect of PMMA on the crystalline, dielectric, and electric energy storage properties of P(VDF‐co‐TrFE). PMMA addition could reduce the crystallinity dramatically as well as the crystal size due to its dilution effect and impediment effect on the crystallization of P(VDF‐co‐TrFE). PMMA introduction is also responsible for the phase transition of P(VDF‐co‐TrFE) from α phase into γ phase. As expected, both the dielectric constant and loss of the blends are reduced as PMMA addition increases for the dilute, decoupling, and confinement effect of PMMA on the relaxation behavior of crystal phases of P(VDF‐co‐TrFE) under external electric field. As a result, both the maximum and remnant polarization of the blends are significantly depressed. The irreversible polarization of P(VDF‐co‐TrFE) is effectively restricted by the addition of PMMA due to its impeding effect on the crystallization of P(VDF‐co‐TrFE) and restricting effect on the switch of the polar crystal domains. Therefore, the energy loss induced by the ferroelectric relaxation of P(VDF‐co‐TrFE) is significantly reduced to less than 25% at an electric field of 450 MV/m while the energy storage density is well maintained at about 10 J/cm−3 in the blend with 30 wt % PMMA. The results may help to understand how the ferroelectric relaxation affects the energy loss of ferroelectrics fundamentally and design more desirable materials for high energy storage capacitors. © 2013 Wiley Periodicals, Inc.

Authors: Markar S R , Karthikesalingam A , Di Franco F , Harris A M 
Published: November 2013

Abstract

Background
The aim of this systematic review and meta-analysis was to compare clinical outcomes following single-incision laparoscopic appendicectomy (SILA) and conventional multiport laparoscopic appendicectomy (CLA) for the treatment of acute appendicitis.

Methods
An electronic search of MEDLINE, Embase, Web of Science and Cochrane Library databases was performed. Publications were included if they were clinical trials randomizing patients with appendicitis to SILA or CLA. Outcome measures evaluated included operating time, length of hospital stay, total postoperative complications, and, specifically, wound infection, intra-abdominal collection and ileus. Weighted mean difference was calculated for the effect size of SILA on continuous variables, and pooled odds ratios were calculated for discrete variables.

Results
The literature search identified seven randomized clinical trials that met the inclusion criteria for meta-analysis. In total, 1108 appendicectomies were included, 555 SILA and 553 CLA procedures. There were no significant differences between the groups in the incidence of total postoperative complications, wound infection, intra-abdominal collection, ileus or length of hospital stay. However, SILA was associated with a significantly longer operating time compared with CLA (weighted mean difference 6·96 (95 per cent confidence interval 3·79 to 10·12) min; P &lt; 0·001). Insertion of an additional port was required in 7·6 per cent of patients undergoing SILA.

Conclusion
SILA is a safe procedure for the treatment of acute appendicitis, with comparable clinical outcome to CLA when undertaken by experienced laparoscopic surgeons.

Abstract

Background
Most patients requiring an extended right hepatectomy (ERH) have an inadequate standardized future liver remnant (sFLR) and need preoperative portal vein embolization (PVE). However, the clinical and oncological impact of PVE in such patients remains unclear.

Methods
All consecutive patients presenting at the M. D. Anderson Cancer Center with colorectal liver metastases (CLM) requiring ERH at presentation from 1995 to 2012 were studied. Surgical and oncological outcomes were compared between patients with adequate and inadequate sFLRs at presentation.

Results
Of the 265 patients requiring ERH, 126 (47·5 per cent) had an adequate sFLR at presentation, of whom 123 underwent a curative resection. Of the 139 patients (52·5 per cent) who had an inadequate sFLR and underwent PVE, 87 (62·6 per cent) had a curative resection. Thus, the curative resection rate was increased from 46·4 per cent (123 of 265) at baseline to 79·2 per cent (210 of 265) following PVE. Among patients who underwent ERH, major complication and 90-day mortality rates were similar in the no-PVE and PVE groups (22·0 and 4·1 per cent versus 31 and 7 per cent respectively); overall and disease-free survival rates were also similar in these two groups. Of patients with an inadequate sFLR at presentation, those who underwent ERH had a significantly better median overall survival (50·2 months) than patients who had non-curative surgery (21·3 months) or did not undergo surgery (24·7 months) (P = 0·002).

Conclusion
PVE enabled curative resection in two-thirds of patients with CLM who had an inadequate sFLR and were unable to tolerate ERH at presentation. Patients who underwent curative resection after PVE had overall and disease-free survival rates equivalent to those of patients who did not need PVE.

Published: November 2013

AbstractBackgroundInfectious complications remain a serious threat to patients with multiple trauma. Susceptibility and response to infection is, in part, heritable. The lectin pathway plays a major role in innate immunity. The aim of this study was to assess whether single nucleotide polymorphisms (SNPs) in three key genes within the lectin pathway affect susceptibility to infectious complications in severely injured patients.MethodsA prospective cohort of severely injured patients admitted to a level I trauma centre between January 2008 and April 2011 were genotyped for SNPs in MBL2 (mannose-binding lectin 2), MASP2 (MBL-associated serine protease 2) and FCN2 (ficolin 2). Association of genotype with prevalence of positive culture findings and infection was tested by χ2 and logistic regression analysis.ResultsA total of 219 patients were included, of whom 112 (51·1 per cent) developed a positive culture from sputum, wounds, blood or urine. A systemic inflammatory response syndrome (SIRS) developed in 139 patients (63·5 per cent), sepsis in 79 (36·1 per cent) and septic shock in 37 (16·9 per cent). Patients with a MBL2 exon 1 variant allele were more prone to positive wound cultures (odds ratio (OR) 2·51, 95 per cent confidence interval 1·12 to 5·62; P = 0·025). A MASP2Y371D DD genotype predisposed to SIRS (OR 4·78, 1·06 to 21·59; P = 0·042) and septic shock (OR 2·53, 1·12 to 4·33; P = 0·003). A FCN2A258S AS genotype predisposed to positive wound cultures (OR 3·37, 1·45 to 7·85; P = 0·005) and septic shock (OR 2·18, 1·30 to 4·78; P = 0·011).ConclusionSeverely injured patients with SNPs in MBL2, MASP2 Y371D and FCN2 A258S of the lectin pathway of complement activation are significantly more susceptible to positive culture findings, and to infectious complications, SIRS and septic shock than patients with a wildtype genotype.
