Published: January 2014

Abstract
Background. The primary aim of this study was to evaluate the diagnostic accuracy of ultrasound (US) in the study of superficial lymph nodes during the follow-up of patients surgically treated for skin tumours. The secondary objective was to compare positive cytological results with histological reports.
Patients and methods. From 2004 to 2011, 480 patients (male/female: 285/195; median age 57 years; prevalent skin tumour: melanoma) underwent US-guided fine-needle aspiration biopsy (FNAB) of suspicious recurrent lymph nodes. An expert radiologist first performed US testing of the lymph nodes, expressing either a negative or positive outcome of the test. Subsequently, US-guided FNAB was performed. FNAB positive patients were subjected to lymphadenectomy; the patients who tested negative underwent the follow-up.
Results. The size of lymph nodes was ≤ 2 cm in 90% of cases. Out of the 336 (70%) US “positive” patients, 231 (68.8%) were FNAB positives. Out of the 144 (30%) US “negatives”, 132 (91.7%) were FNAB negatives. The sensitivity and specificity of the US were 95% and 55.7%, respectively; the negative predictive value was 91.7% and the positive predictive value was 68.8%. Definitive histological results confirmed FNAB positivity in 97.5% of lymphadenectomies.
Conclusions. US is a sensitive method in the evaluation of superficial lymph nodes during the follow-up of patients with skin tumours. High positive predictive value of cytology was confirmed.

Abstract
The representatives of the genus Compsopogon Montagne in Bory et Durieaux (Rhodophyta) are basically tropical or subtropical algae. In central Europe they are only found in aquaria and in water bodies affected by thermal effluents, like the species C. aeruginosus (J. Agardh) Kützing in the Pulkau River (Austria), a tributary of the Dyje /Thaya River (Austria, Czech Republic). The first observation of this species was made in 2007 in the Pulkau River. In autumn 2010 the species was also observed at lower densities in an approximately 20 km section of the Dyje/Thaya River between the mouth of the Pulkau River (A) and the Nové Mlýny Reservoir (CR). Recently, the species was found also in Skryjský Brook, a tributary of the Jihlava River, below the cooling water effluent from the Dukovany Nuclear Power Plant, South Moravia, Czech Republic. This is the second finding of representatives of the genus Compsopogon in rivers in central Europe.
Changing Attitude of Women towards Infertility and Motherhood
Authors: Harasankar Adhikari 
Published: January 2014

Abstract The present study was conducted among the employed women (N=50) at their reproductive age (25-35 years) of urban Kolkata to elucidate their changing attitudes towards infertility and motherhood. We found that the women were very much attentive to their personal happiness and career. They did not believe to perform their traditional female roles because in their opinion it was a restriction of achieving their equity and justice in our patriarchal society. They were engrossed into most modern urban mode of life. They did not prefer to enter into their marital relation because it would be a threat to cherish their happiness. Even in their opinion infertility would not be a stigma in women’s lives because it would be an obstacle for their freedom and self progress in their working life. But they would prefer to enjoy the taste of motherhood otherwise rather than biologically. Thus reproductive rights of women were violated through their overall behaviour.
A clinical comparison of high dose and low dose of Suxamethonium
Authors: Yadav RK , Majhi PC , Tiwari D 
Published: January 2014

Background: Suxamethonium having its rapid onset and short duration of action makes this drug unique amongst the neuromuscular blocking drugs described so far. However, use of suxamethonium is associated with a large number of undesirable side effects. Objective: To evaluate clinical effects of high and low dose of suxamethonium and to determine whether lower dose of suxamethonium can be used for any beneficial effects in terms of its various adverse effects e.g. cardiovascular responses, post-operative muscle pains and intraocular pressure. Methods: A total of 100 patients were included in this prospective study. All these patients on preoperative clinical evaluation were assessed to have adequate airway. All the patients were divided in two groups, low dose group (group I) and High dose group (group II) with 50 patients in each at random. A standard anesthetic technique was adhered to all the patients and following parameters were observed on comparative basis: a. Fasciculation and post operative myalgia. b. Cardiovascular effects, c. Intraocular pressure. Observation: The incidence of post Suxamethonium pain was significantly greater in group II. Increase in heart rate from baseline was significant in both groups. There was no significant difference between the two groups in the diastolic pressure but rise in systolic blood pressure was significant at all assessment times in both groups. This rise from control was statistically significant. Conclusion: Suxamethonium can be used in lower doses (0.5 mg/kg) in elective cases without airway compromise. It gives benefits of reduced muscle pains, cardiovascular responses and intraocular hypertension.

Karoo, la répression jusqu'à la mort
Authors: Nayrou Félicie 
Published: January 2014

Dans un roman étonnant, le personnage central, Karoo, donne à voir de façon spectaculaire le déploiement de la répression sous plusieurs aspects. La répression consciente et travaillée des affects devient peu à peu recherche et tentative d’écrasement de tout mouvement pulsionnel – sexuel et/ou agressif – et de toute émergence psychique. Elle s’accompagne de clivages et de dénis ainsi que de pressions d’un moi idéal dont les impératifs finissent par aveugler le héros. In fine , le lecteur psychosomaticien peut reconstruire l’enchaînement traumatisme/répression/somatisation, sous le règne de la destructivité.
Paradox reconsidered: Methane oversaturation in well‐oxygenated lake waters

Published: January 2014

The widely reported paradox of methane oversaturation in oxygenated water challenges the prevailing paradigm that microbial methanogenesis only occurs under anoxic conditions. Using a combination of field sampling, incubation experiments, and modeling, we show that the recurring mid‐water methane peak in Lake Stechlin, northeast Germany, was not dependent on methane input from the littoral zone or bottom sediment or on the presence of known micro‐anoxic zones. The methane peak repeatedly overlapped with oxygen oversaturation in the seasonal thermocline. Incubation experiments and isotope analysis indicated active methane production, which was likely linked to photosynthesis and/or nitrogen fixation within the oxygenated water, whereas lessening of methane oxidation by light allowed accumulation of methane in the oxygen‐rich upper layer. Estimated methane efflux from the surface water was up to 5 mmol m−2 d−1. Mid‐water methane oversaturation was also observed in nine other lakes that collectively showed a strongly negative gradient of methane concentration within 0–20% dissolved oxygen (DO) in the bottom water, and a positive gradient within ≥ 20% DO in the upper water column. Further investigation into the responsible organisms and biochemical pathways will help improve our understanding of the global methane cycle.
An Empirical Analysis of the Impact of Fuel Costs on the Level and Distribution of Manufacturing Inventory in the United States
Authors: Ke Jian-yu “Fisher” , Dresner Martin , Yao Yuliang 
Published: January 2014

Abstract
While fuel costs have become an important factor in supply chain management, the impact of fuel costs on inventory levels and the distribution of inventories remains unclear. Location theory suggests that firms will relocate inventories to regions with lower fuel costs, leading to lower inventories in the states with higher fuel costs. In contrast, inventory theory suggests that firms will ship orders in greater quantity with less frequency when fuel costs are high, thus resulting in higher inventories in states with higher fuel costs. Using state-level cross-sectional, time-series data for manufacturing industries in the United States during 1994–2006, we empirically examine how fuel price disparities impact the location and dispersion of inventories. Our major findings are that: (1) states with higher fuel costs have lower inventories ceteris paribus; (2) there are lower inventory deviations across states when fuel costs rise; that is, the inventory distribution becomes flatter; and (3) when fuel costs increase, states with higher production output increase their inventories, while states with higher expenditures (as indicated by higher GDPs) experience relative decreases in inventories, suggesting that inventories are relocated from points of demand to points of production. We further quantify that a 1 percent increase in the gasoline price for a state results in a 0.40 percent reduction in inventory levels in the state. Public policy and managerial implications are discussed.
Assessing the Impact of Sarbanes-Oxley Act on the Logistics Industry:
Authors: Srinivasan Mahesh , Chandra Akhilesh 
Published: January 2014

AbstractRegulatory compliance imposes economic costs on organizations and can affect their competitive advantage. Using Sarbanes-Oxley (SOX) Act as the context, we examine its economic consequences on the operating performance of the logistics industry, including 3PLs. Passed in July 2002, SOX mandates widespread and radical corporate governance reforms with the goal of reinstating investors' confidence in the financial reporting process in particular, and the financial system in general. Little evidence is available regarding the economic consequences of such reforms on the logistics industry, especially within private and small organizations (such as logistics service providers) that, unlike public organizations, do not have direct SOX compliance and reporting obligations. Our findings suggest that logistics firms in our sample invest in key resources (e.g., managerial expertise and technology) to comply with SOX, experience organizational changes (with associated negative effects) following SOX, manage their existing workforce to comply with SOX, and do not perceive significant advantages from being SOX compliant. Our findings have significant managerial implications for both logistics firms and their supply chain trading partners.
Gender Differences in Nicotine Induced Dyslipidemia and Hyperglycemia in Mice
Authors: Samina Bano  , Shabana Saeed  
Published: January 2014

The purpose of this study is to examine the prevalence of metabolic syndrome in nicotine treated male and female mice and to evaluate gender related differences. For these purposes adult male and female BALB/C mice were subjected to chronic nicotine treatment (3.08mg/100ml in drinking water) for 4 weeks. Serum glucose, albumin, corticosterone and lipid profile levels were determined. Body weight changes were also monitored. We have found that nicotine treatment raises total cholesterol and glucose levels more in male as compared to female mice. Low density lipoprotein cholesterol (LDL-C) levels were increased by 35% (P<0.01) only in male mice. However rise in triglycerides were greater in females (28%) than males (21%) when compared with their respective controls. Serum albumin levels were increased in both sexes showing 13% greater increase in males as compared to females. However nicotine treatment had no effect on high density lipoprotein cholesterol, corticosterone levels and body weights in both genders. It is concluded that nicotine use is positively associated with LDL-C in males; the results are discussed in relation to prevalence of metabolic syndrome andrisk of cardiovascular events in nicotine users.

Abstract
A 61-year-old man presented to our hospital with hypercalcemia and elevated C reactive protein (CRP). Evaluation revealed renal cell carcinoma (RCC) with metastasis to lung, bone, and brain. He underwent partial resection of the right kidney and a left nephrectomy. Histopathologic findings of resected tumors were consistent with clear cell RCC. Whole-brain irradiation was performed for management of brain metastasis. Postoperatively, he was treated with molecularly targeted therapy using a mammalian target of rapamycin inhibitor. Approximately 14 months later, he suffered an episode of upper gastrointestinal bleeding with secondary anemia and melena. Upper gastrointestinal endoscopy revealed a distinctly protruding lesion in the gastric body. Biopsy of the gastric lesion showed metastatic clear cell RCC. He underwent partial gastrectomy. His postoperative course was uneventful. However, 4 months after surgery, he died from brain metastasis. Metastatic RCC to the stomach, although rare, should be suspected in any patient with a history of RCC who presents with gastrointestinal symptoms.

Published: January 2014

AbstractEvidence of the association between blood transfusions and its impact on prognostic outcomes in patients who undergo curative resection of colorectal cancer remains controversial. The aim of this study was to determine whether receiving peri-operative blood transfusions during curative colorectal cancer resection affected overall survival, cancer-related survival, and cancer recurrence. This retrospective study was undertaken at The Royal Brisbane and Women's Hospital, Australia, between 1984 and 2004. The outcomes of 1370 patients undergoing curative colorectal cancer resection for TNM stage I to III were analyzed. Four hundred twenty three patients (30.9%) required transfusion and 947 patients (69.1%) did not. Peri-operative transfusion was associated with higher rates of cancer recurrence on multivariate analysis (P = 0.024, RR, 1.257, 95% CI, 1.03–1.53); however, it was not independently associated with poorer overall or cancer-related survival. Where the aim is curative resection, this study contributes to a body of evidence that blood transfusions may be associated with poorer outcomes.

Published: January 2014

AbstractThe aim of this study was to evaluate the results of cases with pilonidal sinus (PS) disease that underwent Limberg flap (LF) transposition and to compare the short and long-term results of early discharge cases with those in the literature. A total of 345 patients who underwent rhomboid excision and LF transposition for PS were evaluated retrospectively. No major anesthetic or surgical complications occurred. Partial wound dehiscence, localized flap necrosis, hematoma, wound infection, and seroma rates were determined as 4.0, 2.1, 1.5, 3.3, and 3.7% respectively. All patients other than those with a hematoma or localized necrosis were discharged with a drain in place 24 hours after the operation. The recurrence rate was 3.9% after a mean 33.1-month follow-up (range, 6–72 months). As a result, we found that short and long-term results of patients who underwent LF and were discharged 24 hours after the operation were similar to those in the literature. We suggest that patients without postoperative complications, such as hematoma or flap necrosis, can be discharged early.
The influence of ambient fault temperature on flash‐heating phenomena
Authors: Passelègue François X. , Goldsby David L. , Fabbri Olivier 
Published: January 2014

AbstractRecent high‐velocity friction experiments on room temperature rocks reveal a dramatic weakening caused by extreme frictional heating and thermal degradation of the strength of microscopic asperity contacts on a slip surface, i.e., “flash” heating. Here we explore the effects of elevated ambient fault temperature, up to that at the base of the Earth's seismogenic zone, on the flash‐heating behavior of quartzite, Westerly granite, and India gabbro. The experiments demonstrate that elevated ambient fault temperature causes 1) an increase in the characteristic weakening velocity for flash heating, and 2) an increase in the friction coefficient at a given velocity above this characteristic weakening velocity. These unexpected results are reconciled with flash‐heating theory when temperature‐specific values of various material parameters are incorporated in existing constitutive descriptions of flash heating. Our results suggest that constitutive equations for flash heating can be extrapolated with confidence to the elevated ambient temperatures of the seismogenic zone.
Effects of Mackenzie River discharge and bathymetry on sea ice in the Beaufort Sea

Published: January 2014

AbstractMackenzie River discharge and bathymetry effects on sea ice in the Beaufort Sea are examined in 2012 when Arctic sea ice extent hit a record low. Satellite‐derived sea surface temperature revealed warmer waters closer to river mouths. By 5 July 2012, Mackenzie warm waters occupied most of an open water area about 316,000 km2. Surface temperature in a common open water area increased by 6.5°C between 14 June and 5 July 2012, before and after the river waters broke through a recurrent landfast ice barrier formed over the shallow seafloor offshore the Mackenzie Delta. In 2012, melting by warm river waters was especially effective when the strong Beaufort Gyre fragmented sea ice into unconsolidated floes. The Mackenzie and other large rivers can transport an enormous amount of heat across immense continental watersheds into the Arctic Ocean, constituting a stark contrast to the Antarctic that has no such rivers to affect sea ice.

Published: January 2014

AbstractThis paper describes a novel method for quantitatively and routinely identifying auroral breakup following substorm onset using the Time History of Events and Macroscale Interactions during Substorms all‐sky imagers. Substorm onset is characterized by a brightening of the aurora that is followed by auroral poleward expansion and auroral breakup. This breakup can be identified by a sharp increase in the auroral intensity i(t) and the time derivative of auroral intensity i(t). Utilizing both i(t) and i'(t), we have developed an algorithm for identifying the time interval and spatial location of auroral breakup during the substorm expansion phase based solely on quantifiable characteristics of the optical auroral emissions. We compare the time interval determined by the algorithm to independently identified auroral onset times from three previously published studies. In each case the time interval determined by the algorithm is within error of the onset independently identified by the prior studies. We further show the utility of the algorithm by comparing the breakup intervals determined using the automated algorithm to an independent list of substorm onset times. We demonstrate that 50% of the breakup intervals characterized by the algorithm are within the uncertainty of the times identified in the list. The quantitative description and routine identification of an interval of auroral brightening during the substorm expansion phase provides a foundation for unbiased statistical analysis of the aurora and to probe the physics of the auroral substorm and identify the processes leading to auroral substorm onset.
