    Full Text Available Aim: The aims of this retrospective study were to evaluate localized giant cell tumors of the tendon sheath (GCTTS with Magnetic Resonance (MR imaging findings and to review the epidemiological features of the disease. We also evaluated the literature regarding GCTTS and performed an analysis of the available information. Material and Method: We retrospectively reviewed the MR images of 25 histologically proven cases of GCTTS of the finger during the period between 2012-2014. In addition, a retrospective analysis of the patients’ records was carried out, and age, gender, site and size of lesion, recurrence, and MRI findings were reviewed. Results: The patients were predominantly female (n = 16 and had a mean age of 51.9 ± 12.8 years. Nine patients were male with a mean age of 45.1 ± 13.4 years. The size of the tumors ranged from 6 mm to 30 mm, with a mean size of 15.3±6.8 mm. Tumors were present on the right hand in 15 patients and on the left hand in 10 patients. Among women, 11 tumors were located on the right hand and 5 were found on the left. In men, 4 of the tumors were located on the right hand and 5 were on the left. The most frequent digit on which tumors were found was the index finger, accounting for 40% of cases (n=10. The most frequent location was the index finger for both women (n=6 and men (n=4. All of the lesions were described as well-circumscribed, encapsulated, lobulated, or multilobulated solitary masses with MR imaging. Signal intensity on T1 weighted images (WI was equal to that of skeletal muscle in 23 cases. In two cases, signal intensity was slightly higher. On T2WIs, the signal intensities tended to be between those of skeletal muscle and fat in all of the cases. All of the lesions showed mild to moderate contrast enhancement when compared with precontrast images. There was no statistically significant differences between male and female patients in terms of age, tumor side, involved digit, and highest tumor size

    This prospective study sought to investigate the clinical, radiological and electroencephalographic (EEG) characteristics of seizures in elderly stroke patients, and their outcomes. Over a 2-year study period, 158 consecutive eldedy patients with stroke were examined and followed up. Of these patients, 32 (20%) developed seizures, primarily related to stroke, within a follow up period between 5 months and 2 years. Of these 32 cases, 20 experienced infarctions, and 12 experienced hemorrhages. Involvement of cortical regions was detected in most of the patients exhibiting seizures. In these patients, 44% of the lesions involved cortical areas exclusively or in addition to subcortical areas observed on computed tomography (CT) images. Twenty-five patients (78%)developed early seizures (within 2 weeks after stroke), and half exhibited immediate post-stroke seizures. None of the patients exhibiting early onset seizures developed recurrent seizures or epilepsy, while 57% of late onset seizures (four cases) developed epilepsy. No specific EEG patterns were apparent in those who later developed epilepsy. Overall, early onset seizures after stroke were found to be relatively common, and did not affect outcome. Late onset seizures were less common, but were associated with chronic epilepsy.

    Full Text Available PURPOSE: To evaluate anatomical and functional results of 25-gauge transconjunctival sutureless pars plana vitrectomy in patients with uveitis. METHODS: Vitrectomy was performed on 20 eyes with residual vitritis secondary to infectious and noninfectious uveitis. Patients were evaluated 1 week before surgery and after surgery at day 1, week 1, week 4 and week 12. Visual acuity (VA, intraocular pressure, anterior chamber cells and flare and vitreous haze were measured. RESULTS: Mean VA improved from 2.06 ± 0.94 logMAR before surgery to 0.58 ± 0.46 logMAR at week 12 (p<0.05. No case required conversion to standard 20-gauge instrumentation or suture placement, no intraoperative complications were noted. Transient postoperative hypotony was seen in three eyes. One patient with toxoplasmic retinochoroiditis had a relapse during follow-up. CONCLUSION: 25-gauge vitrectomy has proven its efficacy on cleansing vitreous opacities and improving visual acuity on patients with residual vitritis secondary to uveitis with minimal postoperative inflammation and complications.

    Exactly twenty five years ago the world of high energy physics was set on fire by the discovery of a new particle with an unusually narrow width at 3095 MeV, known popularly as the $J/\\Psi$ revolution. This discovery was very decisive in our understanding as well as formulating the current picture regarding the basic constituents of nature. I look back at the discovery, pointing out how unexpected, dramatic and significant it was.

    To assess the efficacy of tocilizumab (TCZ) for the treatment of juvenile idiopathic arthritis (JIA)-associated uveitis. We conducted a multicenter study of patients with JIA-associated uveitis that was refractory to conventional immunosuppressive drugs and anti-tumor necrosis factor (anti-TNF) agents. We assessed 25 patients (21 female; 47 affected eyes) with a mean ± SD age of 18.5 ± 8.3 years. Uveitis was bilateral in 22 patients. Cystoid macular edema was present in 9 patients. Ocular sequelae found at initiation of TCZ included cataracts (n = 13), glaucoma (n = 7), synechiae (n = 10), band keratopathy (n = 12), maculopathy (n = 9), and amblyopia (n = 5). Before TCZ, patients had received corticosteroids, conventional immunosuppressive drugs, and biologic agents (median 2 [range 1-5]), including adalimumab (n = 24), etanercept (n = 8), infliximab (n = 7), abatacept (n = 6), rituximab (n = 2), anakinra (n = 1), and golimumab (n = 1). Patients received 8 mg/kg TCZ intravenously every 4 weeks in most cases. TCZ yielded rapid and maintained improvement in all ocular parameters. After 6 months of therapy, 79.2% of patients showed improvement in anterior chamber cell numbers, and 88.2% showed improvement after 1 year. Central macular thickness measured by optical coherence tomography in patients with cystoid macular edema decreased from a mean ± SD of 401.7 ± 86.8 μm to 259.1 ± 39.5 μm after 6 months of TCZ (P = 0.012). The best-corrected visual acuity increased from 0.56 ± 0.35 to 0.64 ± 0.32 (P uveitis was observed in 19 of 25 patients. Significant reduction in the prednisone dosage was also achieved. The main adverse effects were severe autoimmune thrombocytopenia in 1 patient, pneumonia and then autoimmune anemia and thrombocytopenia in 1 patient, and viral conjunctivitis and bullous impetigo in 1 patient. TCZ appears to be a useful therapy for severe refractory JIA

    Twenty-five years ago this month, Thomas Gold published a seminal manuscript suggesting the presence of a "deep, hot biosphere" in the Earth's crust. Since this publication, a considerable amount of attention has been given to the study of deep biospheres, their role in geochemical cycles, and their potential to inform on the origin of life and its potential outside of Earth. Overwhelming evidence now supports the presence of a deep biosphere ubiquitously distributed on Earth in both terrestrial and marine settings. Furthermore, it has become apparent that much of this life is dependent on lithogenically sourced high-energy compounds to sustain productivity. A vast diversity of uncultivated microorganisms has been detected in subsurface environments, and we show that H2, CH4, and CO feature prominently in many of their predicted metabolisms. Despite 25 years of intense study, key questions remain on life in the deep subsurface, including whether it is endemic and the extent of its involvement in the anaerobic formation and degradation of hydrocarbons. Emergent data from cultivation and next-generation sequencing approaches continue to provide promising new hints to answer these questions. As Gold suggested, and as has become increasingly evident, to better understand the subsurface is critical to further understanding the Earth, life, the evolution of life, and the potential for life elsewhere. To this end, we suggest the need to develop a robust network of interdisciplinary scientists and accessible field sites for long-term monitoring of the Earth's subsurface in the form of a deep subsurface microbiome initiative.

    Los Alamos National Laboratory (the Laboratory) is the nation's premier national security science laboratory. Its mission is to develop and apply science and technology to ensure the safety, security, and reliability of the United States (U.S.) nuclear stockpile; reduce the threat of weapons of mass destruction, proliferation, and terrorism; and solve national problems in defense, energy, and the environment. The fiscal year (FY) 2013-2037 Twenty-Five Year Site Plan (TYSP) is a vital component for planning to meet the National Nuclear Security Administration (NNSA) commitment to ensure the U.S. has a safe, secure, and reliable nuclear deterrent. The Laboratory also uses the TYSP as an integrated planning tool to guide development of an efficient and responsive infrastructure that effectively supports the Laboratory's missions and workforce. Emphasizing the Laboratory's core capabilities, this TYSP reflects the Laboratory's role as a prominent contributor to NNSA missions through its programs and campaigns. The Laboratory is aligned with Nuclear Security Enterprise (NSE) modernization activities outlined in the NNSA Strategic Plan (May 2011) which include: (1) ensuring laboratory plutonium space effectively supports pit manufacturing and enterprise-wide special nuclear materials consolidation; (2) constructing the Chemistry and Metallurgy Research Replacement Nuclear Facility (CMRR-NF); (3) establishing shared user facilities to more cost effectively manage high-value, experimental, computational and production capabilities; and (4) modernizing enduring facilities while reducing the excess facility footprint. Th is TYSP is viewed by the Laboratory as a vital planning tool to develop an effi cient and responsive infrastructure. Long range facility and infrastructure development planning are critical to assure sustainment and modernization. Out-year re-investment is essential for sustaining existing facilities, and will be re-evaluated on an annual

    Twenty-five cases of feline bronchial disease were identified retrospectively. The criteria for inclusion were consistent clinical signs or histopathology and no other identifiable aetiology. Patient records were analysed to determine historical, clinical, clinicopathologic and radiographic features. The main presenting complaints were coughing and dyspnoea. The most common physical finding was dyspnoea. The majority of radiographs had a bronchial pattern either as the sole change or as a component of a mixed pattern. Bronchoalveolar lavage cytology was neutrophilic or eosinophilic in the majority of cats. There was no association between age, breed, sex, clinical signs, bronchoalveolar lavage cytology or radiographic severity and disease severity.

    Rapidly involuting congenital hemangiomas are very rare vascular tumours, that are characterized for being completely developed at birth and for involuting in a short period of time after birth. We describe a case series of 25 patients with rapidly involuting congenital hemangiomas. Twelve patients were male and 13 female; they were all born at term. Lesions were small in 17 cases and big in 8. No patient needed active intervention and all lesions showed a rapid initial involution.

    Background Choledochal cyst is rare in western countries. The relatively high incidence of coexistent hepatobiliary disease increases the difficulty of the surgical management of choledochal cyst. Here we analyze the diagnosis and treatment of congenital bile duct cyst in 122 Chinese adults.Methods The clinical data of 122 patients with congenital choledochal cysts admitted from 1981 to 2006 were analyzed.Results Clinical symptoms in most cases were nonspecific, resulting in delayed diagnosis. Sixty-one patients (50%) had coexistent pancreatobiliary disease. Among the 122 patients, 119 patients underwent ultrasonic examination;ERCP/MRCP was performed in 63 cases and CT in 102 cases. Abnormal pancreatobiliary duct junction was found in 48 patients. Sixteen patients had malignant lesions in the bile duct, arising in 11 of them from incomplete choledochal cyst that underwent various operations including cystenterostomy or cystojejunostomy. There was significant difference between the patients who underwent incomplete cyst resection and complete cyst resection in malignancy rate of bile duct (Chi square test, P= 0.000; odds ratio, 7.800; 95 % confidence interval, 2.450 to 24.836).Conclusions ERCP, CT and MRCP had proved their great values in the classification of the disease. Cyst excision with Roux-en-Y hepaticojejunostomy is recommended as the treatment of choice for patients with type Ⅰ or type Ⅳ cysts. For type Ⅴ cyst (Caroli's disease) with recurrent cholangitis, liver transplantation should be considered.

    It is accepted by the surgical community that laparoscopic cholecystectomy (LC) is the technique of choice in the treatment of symptomatic cholelithiasis. However, more controversial is the standardization of system implementation in Ambulatory Surgery because of its different different connotations. This article aims to update the factors that influence the performance of LC in day surgery, analyzing the 25 years since its implementation, focusing on the quality and acceptance by the patient. Individualization is essential: patient selection criteria and the implementation by experienced teams in LC, are factors that ensure high guarantee of success.

    The incorporation, 25 years ago, of transjugular intrahepatic portosystemic shunting, better known by the acronym TIPS, represents an indisputable improvement in the treatment and management of patients with symptoms due to portal hypertension. This article discusses the origins of the technique and the technical innovations that have been progressively added through the years. The implantation of coated stents, which protect the stent from processes in the parenchymal track that can lead to stenosis, have helped ensure long-term patency, thus reducing the need for reintervention. Solid evidence from valuable publications has situated TIPS at the forefront of the treatment options in a wide variety of clinical situations associated with portal hypertension.

    Full Text Available OBJECTIVE: Aspiration can cause a variety of pulmonary syndromes, some of which are not well recognized. The objective of this study was to assess the demographic, clinical, radiological, and histopathological correlates of diffuse aspiration bronchiolitis (DAB, a bronchiolocentric disorder caused by recurrent aspiration. METHODS: This was a retrospective study of 20 consecutive patients with DAB seen at the Mayo Clinic in Rochester, Minnesota, between January 1, 1998 and June 30, 2014. RESULTS: The median age of the patients was 56.5 years (range, 22-76 years, and the male/female ratio was 2.3:1.0. In 18 patients, the diagnosis of DAB was based on the results of a lung biopsy; in the 2 remaining patients, it was based on clinical and radiological features, together with documented aspiration observed in a videofluoroscopic swallow study. In 19 patients (95%, we identified predisposing factors for aspiration, including gastroesophageal reflux disease (GERD, drug abuse, and dysphagia. Common presenting features included cough, sputum production, dyspnea, and fever. Twelve patients (60% had a history of recurrent pneumonia. In all of the patients, chest CT revealed bilateral pulmonary infiltrates consisting of micronodules and tree-in-bud opacities. In the majority of patients, interventions aimed at preventing recurrent aspiration (e.g., anti-GERD therapies led to improvement in the symptoms of DAB. CONCLUSIONS: Young to middle-aged subjects with recognizable predisposing factors for aspiration and who report a history of recurrent pneumonia are at increased risk for DAB. Although DAB is not well recognized, certain chest CT features are characteristic of the disorder.

    Full Text Available In 1971 many academic economists were predicting that the Bretton Woods system of fixed parities would collapse. Some, most notably Milton Friedman, became excited about the possibility of a floating system because the benefits of international capital mobility can only be achieved through the flexibility in the exchange rate. These economists argued that a floating exchange rate system can ensure positive results more than the fixed parities system. Twenty-five years later, however, there is still no consensus on the matter. The author reviews the post-Bretton Woods experience to highlight some policies and approaches that might be helpful for the future.

    2011-01-01

    The strong symmetric genus of a finite group is the minimum genus of a compact Riemann surface on which the group acts as a group of automorphisms preserving orientation. A characterization of the infinite number of groups with strong symmetric genus zero and one is well-known and the problem is finite for each strong symmetric genus greater than or equal to two. May and Zimmerman have published papers detailing the classification of all groups with strong symmetric genus two through four. Using the computer algebra system GAP, we extend these classifications to all groups of strong symmetric genus up to twenty-five. This paper outlines the approach used for the extension.

    Objective: To determine the larvicidal activity of twenty five plant extracts against Culex quinquefasciatus (Cx. quinquefasciatus). Methods: The larvicidal activity was determined against the third instar larvae of Cx. quinquefasciatus at 1 000 ppm concentration. Larval mortality was assessed after 24 and 48 h. Results: The hexane extracts of Cleistanthus collinus (C. collinus) and Murraya koeingii (M. koeingii) plants showed 100 percent mortality at 24 h bioassay followed by diethyl ether, dichloromethane and ethyl acetate extracts of C. collinus, Leucas aspera (L. aspera), Hydrocotyle javanica (H. javanica), M. koeingii, Sphaeranthus indicus (S. indicus) and Zanthoxylum limonella (Z. limonella) after 48 h exposure. Conclusions: The results indicate larvicidal activity against Cx. quinquefasciatus and further investigations are needed to elucidate this activity against a wide range of all stages of mosquito species and also the active ingredients of the extract responsible for larvicidal activity should be identified.

    Twenty-five years ago this past autumn, we published a short article entitled 'Adherence of bacteria to hydrocarbons: a simple method for measuring cell-surface hydrophobicity' in Volume 9 of FEMS Microbiology Letters. Together with my Ph.D. supervisors, Eugene Rosenberg and David Gutnick, we proposed a method of measuring bacterial cell surface hydrophobicity based on bacterial adherence to hydrocarbon ('BATH', later known as 'MATH', for microbial adhesion to hydrocarbon). The method became popular soon after it was published, and the paper was, for at least the following decade, the Journal's most cited article. It became an ISI 'citation classic' in 1991. This minireview is a rather personal look at the development of the method and its various modifications and other scientific offspring, with the perspective of a quarter-century.

    Purpose: To evaluate the prognostic factors, patterns of failure, and late toxicity in patients treated with chemoradiation (CRT) for anal cancer. Methods and Materials: Consecutive patients with nonmetastatic squamous cell carcinoma of the anus treated by CRT with curative intent between February 1983 and March 2008 were identified through the institutional database. Chart review and telephone follow-up were undertaken to collect demographic data and outcome. Results: Two hundred eighty-four patients (34% male; median age 62 years) were identified. The stages at diagnosis were 23% Stage I, 48% Stage II, 10% Stage IIIA, and 18% Stage IIIB. The median radiotherapy dose to the primary site was 54 Gy. A complete clinical response to CRT was achieved in 89% of patients. With a median follow-up time of 5.3 years, the 5-year rates of locoregional control, distant control, colostomy-free survival, and overall survival were 83% (95% confidence interval [CI] 78-88), 92% (95% CI, 89-96), 73% (95% CI, 68-79), and 82% (95% CI, 77-87), respectively. Higher T stage and male sex predicted for locoregional failure, and higher N stage predicted for distant metastases. Locoregional failure occurred most commonly at the primary site. Omission of elective inguinal irradiation resulted in inguinal failure rates of 1.9% and 12.5% in T1N0 and T2N0 patients, respectively. Pelvic nodal failures were very uncommon. Late vaginal and bone toxicity was observed in addition to gastrointestinal toxicity. Conclusions: CRT is a highly effective approach in anal cancer. However, subgroups of patients fare relatively poorly, and novel approaches are needed. Elective inguinal irradiation can be safely omitted only in patients with Stage I disease. Vaginal toxicity and insufficiency fractures of the hip and pelvis are important late effects that require prospective evaluation.

    Full Text Available Fungal peritonitis is a rare but serious complication of peritoneal dialysis. The aim of this study was to analyze peritonitis rates, associated factors, clinical course, microbiological aspects, therapeutic regimens, and outcome of patients with fungal peritonitis in the dialysis center of a teaching hospital over the last 25 years. A hundred and eighty three episodes of peritonitis were detected and microbiologically documented in 57 patients. Fungi were identified in eight episodes (4.37% occurring in seven female patients. The fungal peritonitis rate was 0.06 episodes/patient-year. Gram and Giemsa stains were positive in five out of eight dialysate fluids. The causative microorganisms were: Candida albicans in five episodes, and Candida parapsilosis, Candida glabrata, and Neosartorya hiratsukae in the remaining three. Antibiotics were administered to all but one patient, within 3 months before fungal peritonitis was detected. All patients required hospitalization, and antifungal therapy was administered in all episodes. The Tenckhoff catheter was removed in seven out of eight fungal peritonitis. All patients recovered from the fungal episodes. In the group of patients studied, it is concluded that recent exposure to antibiotics and female sex, were strongly associated with the development of fungal peritonitis by yeasts. The peritonitis caused by the environmental filamentous fungus did not require antibiotic pressure. Direct microscopy of the dialysate pellet was extremely useful for the prompt management of the fungal episode. Fungal peritonitis preceded by multiple episodes of bacterial peritonitis always determined the definitive dropout of the patient from the peritoneal dialysis program. Patients with de novo yeastrelated peritonitis could continue on the program.La peritonitis fúngica es una complicación infrecuente pero grave de la diálisis peritoneal.

    Classical 3beta-hydroxysteroid dehydrogenase/delta5-delta4 isomerase (3betaHSD) deficiency is a form of congenital adrenal hyperplasia that impairs steroidogenesis in both the adrenals and gonads resulting from mutations in the HSD3B2 gene and causing various degrees of salt-wasting in both sexes and incomplete masculinization of the external genitalia in genetic males. To identify the molecular lesion(s) in the HSD3B2 gene in the 11 patients from the seven new families suffering from classical 3betaHSD deficiency, the complete nucleotide sequence of the whole coding region and exon-intron splicing boundaries of this gene was determined by direct sequencing. Five of these families were referred to Morel's molecular diagnostics laboratory in France, whereas the two other families were investigated by Peter's group in Germany. Functional characterization studies were performed by Simard's group in Canada. Following transient expression in 293 cells of each of the mutant recombinant proteins generated by site-directed mutagenesis, the effect of the 25 mutations on enzyme activity was assessed by incubating intact cells in culture with 10 nM [14C]-DHEA as substrate. The stability of the mutant proteins has been investigated using a combination of Northern and Western blot analyses, as well as an in vitro transcription/translation assay using rabbit reticulocyte lysates. The present report describes the identification of 8 mutations, in seven new families with individuals suffering from classical 3betaHSD deficiency, thus increasing the number of known HSD3B2 mutations involved in this autosomal recessive disorder to 31 (1 splicing, 1 in-frame deletion, 3 nonsense, 4 frameshift and 22 missense mutations). In addition to the mutations reported here in these new families, we have also investigated for the first time the functional significance of previously reported missense mutations and or sequence variants namely, A82T, A167V, L173R, L205P, S213G and K216E, P222H, T259

  8. Twenty-five Years of PTHrP Progress from Cancer Hormone to Multifunctional Cytokine

    Twenty-five years ago a ‘new’ protein was identified from cancers that caused hypercalcemia. It was credited for its ability to mimic parathyroid hormone, and hence was termed parathyroid hormone-related protein (PTHrP). Today it is recognized for its widespread distribution, its endocrine, paracrine, and intracrine modes of action driving numerous physiologic and pathologic conditions with a central role in organogenesis. The multiple biological activities within a complex molecule with paracrine modulation of adjacent target cells present boundless possibilities. The protein structure of PTHrP has been traced, dissected and deleted comprehensively and conditionally, yet numerous questions lurk in its past that will carry into the future. Issues of the variable segments of the protein including the enigmatic nuclear localization sequence are only recently being clarified. Aspects of PTHrP production and action in the menacing condition of cancer are emerging as dichotomies that may represent intended temporal actions of PTHrP. Relative to PTH, the hormone regulating calcium homeostasis, PTHrP ‘controls the show’ locally at the PTH/PTHrP receptor throughout the body. Great strides have been made in our understanding of PTHrP actions, yet years of exciting investigation and discovery are imminent. PMID:22549910

    Human history is also the record of our fascination with the sky, and to look upwards is to follow in the steps of such greats as Galileo and Newton. What they and others once saw in the heavens for the first time, amateur astronomers can discover anew using this guide to twenty-five of the greatest journeys through space.   Starting with our most visible companion the Moon, each chapter offers a step-by-step walk-through of famous astronomical observations from the history of science. Beginning with the easiest targets, sometimes even accessible with the naked eye, the challenges become progressively more difficult. Beginner astronomers and more experienced hobbyists alike can reacquaint themselves with the wonders of our fellow planets and even reach far beyond our own solar system to touch on such incredible phenomena as the birth of new stars in nebula systems and the deceptive nothingness of black holes. The would-be astronaut can spy the International Space Station in orbit with binoculars or the dooms...

  10. The Twenty-five Maiden Ladies’ Tomb and Predicaments of the Feminist Movement in Taiwan

    2010-01-01

    Full Text Available “The Twenty-five Maiden Ladies’ Tomb” is the collective burial site of the female workers who died in a ferry accident on their way to work in 1973. The fact that of the more than 70 passengers on board all 25 who died were unmarried young women, and the taboo in Taiwanese culture that shuns unmarried female ghosts, made the Tomb a fearsome place. Feminists in Gaoxiong (高雄 had for some years wanted the city government to change the tomb’s public image. Their calls were not answered until the Gaoxiong mayor’s office finally allocated money to clean up the gravesite and, as part of the city’s plans to develop urban tourism, to remake it into the tourist-friendly “Memorial Park for Women Labourers”. Consequently, even though the tomb renovation seemed to indicate a triumph of the feminist endeavour, it was more a result of the Gaoxiong city government’s efforts towards culture-led urban revitalization.

  11. Twenty-five winters of unexpected Eurasian cooling unlikely due to Arctic sea-ice loss

    Surface air temperature over central Eurasia decreased over the past twenty-five winters at a time of strongly increasing anthropogenic forcing and Arctic amplification. It has been suggested that this cooling was related to an increase in cold winters due to sea-ice loss in the Barents-Kara Sea. Here we use over 600 years of atmosphere-only global climate model simulations to isolate the effect of Arctic sea-ice loss, complemented with a 50-member ensemble of atmosphere-ocean global climate model simulations allowing for external forcing changes (anthropogenic and natural) and internal variability. In our atmosphere-only simulations, we find no evidence of Arctic sea-ice loss having impacted Eurasian surface temperature. In our atmosphere-ocean simulations, we find just one simulation with Eurasian cooling of the observed magnitude but Arctic sea-ice loss was not involved, either directly or indirectly. Rather, in this simulation the cooling is due to a persistent circulation pattern combining high pressure over the Barents-Kara Sea and a downstream trough. We conclude that the observed cooling over central Eurasia was probably due to a sea-ice-independent internally generated circulation pattern ensconced over, and nearby, the Barents-Kara Sea since the 1980s. These results improve our knowledge of high-latitude climate variability and change, with implications for our understanding of impacts in high-northern-latitude systems.

    Temporalis muscle reconstruction is a necessary step during frontotemporal cranioplasty ensuing decompressive craniectomy (DC). During this procedure, scarring between the temporalis muscle and the dural layer may lead to complicated muscle dissection, which carries an increased risk of dura and muscle damage. At time of DC, temporalis muscle wrapping by an autologous vascularized dural flap can later on facilitate dissection and rebuilding during the subsequent cranioplasty. In a span of 2 years, we performed 57 DCs for different etiologies. In 30 cases, the temporalis muscle was isolated by wrapping its inner surface using the autologous dura. At cranioplasty, the muscle could easily be dissected from the duraplasty. The inner surface was easily freed from the autologous dural envelope, and reconstruction achieved in an almost physiological position. Follow-up examinations were held at regular intervals to disclose signs of temporalis muscle depletion. Twenty-five patients survived to undergo cranioplasty. Muscle dissection could always be performed with no injury to the dural layer. No complications related to temporalis muscle wrapping were recorded. Face asymmetry developed in four cases but it was always with bone resorption. None of the patients with a good neurological recovery reported functional or aesthetic complaints. In our experience, temporalis muscle wrapping by vascularized autologous dura proved to be effective in preserving its bulk and reducing its adhesion to duraplasty, thereby improving muscle dissection and reconstruction during cranioplasty. Functional and aesthetic results were satisfying, except in cases of bone resorption. PMID:24067769

  13. Twenty five years of antismoking movement started by medical students: some further goals.

    Twenty five years ago, medical students of the former Yugoslavia accepted an idea that emerged from the Medical School in Tuzla to carry out a national preventive campaign "January 31st, a Day without Cigarette". This campaign was soon recognized by the World Health Organization (WHO) as one of "the most successful preventive achievement of medical students in Europe". The only contribution that the government made was printing and releasing a postal stamp on January 31st, 1990. During the war in Bosnia, the UN sanctions imposed to Serbia, and the NATO bombing campaign of the F.R. Yugoslavia (Serbia & Montenegro) weakened this antismoking campaign. At the time of the civil war in several Yugoslav republics, more citizens, including children and youth, started to smoke than in previous years. In 2002, January 31st was proclaimed as the National Antismoking Day in Serbia and the "Republic of Srpska" in Bosnia & Herzegovina; the Republic of Slovenia, and to a smaller extent the rest of the "Bosnian Federation", continued to observe this antismoking campaign. In the future, the medical professionals have to look for new ways to help smokers quit smoking and to maintain abstinence. In addition to education and professional advice, they may use smoking cessation interventions, especially to smokers that require elective surgery. Medical students should continue to participate in the national antismoking campaigns, and they could be included in the comprehensive smoking intervention programs to improve their smoking cessation counseling skills. However, the governments should plan and rigorously realize needed measures to control smoking at public places, offices, and other closed working places. Such measures are especially needed in poor and developing countries where many people die unnecessarily.

    A literature review reports increased erythrocyte indices [hemoglobin concentration, hematocrit, mean corpuscular volume, mean corpuscular hemoglobin (MCH), MCH concentration] in subjects with hereditary hemochromatosis (HH). We, therefore, screened 52 consecutive patients with polycythemia vera for 12 HH gene mutations, comparing iron status and red cell parameters between patients positive or negative for HH gene mutations. Our results support the evidence that there is no association between these two conditions.

    The first twenty five semiannual reports of the United States Atomic Energy Commission to Congress cover the major unclassified activities of the Commission from January 1947 through January 1959. In addition to the semiannual summaries, a series of special reports on important atomic energy programs were included in many of the semiannual reports. This cumulative name and subject index provides a guide to the information published in these reports. Beginning in 1960, the Commission will be issuing annual reports, each separately indexed, ceasing the semiannual reporting.

    In the early 1990s, an international working group of experienced renal pathologists, the Renal Histology group, set up a scoring system for biopsies with anti-neutrophil cytoplasmic autoantibody (ANCA)-associated glomerulonephritis. This scoring system subdivided glomerular, interstitial and vascular lesions and served as a tool for the evaluation of all renal biopsies from studies of the European Vasculitis Study Group (EUVAS). Histopathological studies gave new insights into the prediction of renal outcome in patients with ANCA-associated glomerulonephritis. Percentage of normal glomeruli and a selected number of interstitial parameters were reliable predictors of long-term follow-up glomerular filtration rate in all studies. Out of these results, a histopathological classification distinguishing focal, crescentic, mixed and sclerotic classes of ANCA-associated glomerulonephritis was developed. Until today, 13 studies have validated this classification system. Future studies will try to determine if and how renal histology could be helpful in guiding treatment of ANCA-associated glomerulonephritis.

    OBJECTIVE Large consecutive series on the size and location of ruptured intracranial aneurysms (RIAs) are limited, and therefore it has been difficult to estimate population-wide effects of size-based treatment strategies of unruptured intracranial aneurysms. The authors' aim was to define the size and location of RIAs in patients diagnosed with subarachnoid hemorrhage due to aneurysm rupture in a high-volume academic center. METHODS Consecutive patients admitted to a large nonprofit academic hospital with saccular RIAs between 1995 and 2009 were identified, and the size, location, and multiplicity of RIAs were defined and reported by patient sex. RESULTS In the study cohort of 1993 patients (61% women) with saccular RIAs, the 4 most common locations of RIAs were the middle cerebral (32%), anterior communicating (32%), posterior communicating (14%), and pericallosal arteries (5%). However, proportional distribution of RIAs varied considerably by sex; for example, RIAs of the anterior communicating artery were more frequently found in men than in women. Anterior circulation RIAs accounted for 90% of all RIAs, and 30% of the patients had multiple intracranial aneurysms. The median size (measured as maximum diameter) of all RIAs was 7 mm (range 1-43 mm), but the size varied considerably by location. For example, RIAs of the ophthalmic artery had a median size of 11 mm, whereas the median size of RIAs of the pericallosal artery was 6 mm. Of all RIAs, 68% were smaller than 10 mm in maximum diameter. CONCLUSIONS In this large consecutive series of RIAs, 83% of all RIAs were found in 4 anterior circulation locations. The majority of RIAs were small, but the size and location varied considerably by sex. The presented data may be of help in defining effective prevention strategies.

    2016-01-01

    BACKGROUND: Sorbitan sesquioleate (SSO) has been added to fragrance mix I (FM I) as an emulsifier since the 1990s. Being a contact allergen itself, SSO has the potential to cause false-positive reactions to FM I. Recent results obtained with selected FM I-positive patients have shown that 5% have...... concomitant positive reactions to SSO. OBJECTIVES: To investigate the 5-year prevalence of contact allergy to SSO and evaluate the importance of SSO allergy when patch test results for FM I are interpreted. METHODS: This was a retrospective database study of consecutively patch tested eczema patients (n = 4 6...... 3 7) from 2010 to 2014. All patients were tested with our baseline series including FM I and SSO 20% in pet. RESULTS: Sensitization to SSO was identified in 9 (0.2%) patients. The proportion of FM I-positive patients with concomitant positive reactions to SSO was 1.4%. CONCLUSIONS: SSO is a rare...

    The aim of the study was to analyze the clinical use of different types of combination therapy in a large sample of consecutive patients with uncontrolled hypertension referred to Hypertension Centre. We performed a retrospective analysis of combination antihypertensive therapy in 1254 consecutive patients with uncontrolled hypertension receiving at least triple-combination antihypertensive therapy. Among the most prescribed antihypertensive classes were renin-angiotensin blockers (96.8%), calcium channel blockers (82.5%), diuretics (82.0%), beta-blockers (73.0%), centrally acting drugs (56.0%) and urapidil (24.1%). Least prescribed were spironolactone (22.2%) and alpha-1-blockers (17.1%). Thiazide/thiazide-like diuretics were underdosed in more than two-thirds of patients. Furosemide was prescribed in 14.3% of patients treated with diuretics, while only indicated in 3.9%. Inappropriate combination therapy was found in 40.4% of patients. Controversial dual and higher blockade of renin-angiotensin system occurred in 25.2%. Incorrect use of a combination of two antihypertensive drugs with the similar mechanism of action was found in 28.1%, most commonly a combination of two drugs with central mechanism (13.5%). In conclusion, use of controversial or incorrect combinations of drugs in uncontrolled hypertension is common. Diuretics are frequently underdosed and spironolactone remains neglected in general practice. The improper combination of antihypertensive drugs may contribute to uncontrolled hypertension.

  4. Two consecutive partial liver transplants in a patient with Classic Maple Syrup Urine Disease

    Full Text Available Maple syrup urine disease is caused by a deficiency in the branched chain ketoacid dehydrogenase (BCKAD complex. This results in the accumulation of branched chain amino acids (BCAA and branched chain ketoacids in the body. Even when aggressively treated with dietary restriction of BCAA, patients experience long term cognitive, neurological and psychosocial problems. Liver transplantation from deceased donors has been shown to be an effective modality in introducing adequate BCKAD activity, attaining a metabolic cure for patients. Here, we report the clinical course of the first known patient with classic MSUD who received two consecutive partial liver grafts from two different living non-carrier donors and his five year outcome posttransplant. We also show that despite the failure of the first liver graft, and initial acute cellular rejection of the second liver graft in our patient, his metabolic control remained good without metabolic decompensation.

    In Europe, trauma admissions and in particular hip fractures are on the rise. In recent years, health care systems have placed particular emphasis, including financial incentives, on delivering patients quickly and safely to surgery. At our unit, we have observed that hip fracture patients appear to be at significant risk of mortality even up to a year following injury. This study reviews a consecutive population of hip fracture patients to identify predictors of excess risk. Four hundred and sixty-five consecutive patients were treated over a 2-year period at our district general hospital with no ward-based orthogeriatricians. Follow-up was for 1 year following hip fracture admission. Statistical analysis of variables and their influence on 1-year mortality were performed by calculating odd's ratio (OR) using a logistic regression model and a p value year was 50 %. Following hip fracture, we found an overall 1-year mortality rate of 15.1 %. Patients with a time to surgery ≥36 h were at significantly increased risk of mortality even up to 1 year. We did not identify a further reduction in mortality in those operated on within 24 h. Raised ORs (p > 0.05) were found with increasing comorbidity, surgery type, independence on discharge, alcohol ingestion, history of smoking, readmission and several biochemical markers. Minimising mortality risk, even over the longer term, should begin on admission with prompt optimisation of any acute medical or biochemical abnormalities, followed by early surgery and intensive rehabilitation to maintain patients' functional independence.

    OBJECTIVE: To study a strategy of aggressive coronary balloon angioplasty with provisional stenting in allcomers. In randomized trials, stenting has improved the outcome of patients undergoing coronary intervention. However, whether these results hold up in clinical practice is largely unknown. Furthermore, the results of balloon angioplasty have also improved dramatically. It is therefore essential to evaluate the current results of balloon angioplasty and to assess whether stents are required in all patients. METHODS: The authors prospectively studied the occurrence of death, myocardial infarction (MI) and target lesion revascularization (TLR) of a large consecutive group of patients undergoing aggressive balloon angioplasty with provisional stenting. None of the patients received a platelet glycoprotein IIb/IIIa receptor blocker. The results were compared with the outcome of routine stenting in recent randomized trials. RESULTS: Angioplasty was performed in 1058 patients of whom 369 (34.9%) received a stent. The angiographic success rate was 98.9%. During hospital stay, 4.8% of the patients suffered any cardiac event. At one-year follow-up, death occurred in 1.1%, MI in 3.3%, TLR in 12.4% and any event in 16.7% of the patients. Event-free survival at one-year was 82.3%. These results compare favorably with routine stenting in recent trials. CONCLUSIONS: Aggressive balloon angioplasty with provisional stenting yields excellent results in a general patient population.

    Invasive fungal sinusitis is a rare condition that usually occurs in immunocompromised patients and often presents as an orbital apex syndrome. It is frequently misdiagnosed on presentation and is almost always lethal without early treatment. Retrospective case series of 14 consecutive patients with biopsy-proven invasive fungal sinusitis from four tertiary hospitals. Fourteen patients (10 men and 4 women; age range 46-82 years). Retrospective chart review of all patients presenting with invasive fungal sinusitis between 1994 and 2010 at each hospital, with a close analysis of the tempo of the disease to identify any potential window of opportunity for treatment. Demographic data, background medical history (including predisposing factors), symptoms, signs, radiological findings, histopathological findings, treatment approach and subsequent clinical course were recorded and analysed. Only one patient was correctly diagnosed at presentation. Only two patients were not diabetic or immunocompromised. The tempo was acute in two patients, subacute in nine patients and chronic in three patients. In the subacute and chronic cases, there was about 1 week of opportunity for treatment, from the time there was a complete orbital apex syndrome, and still a chance for saving the patient, to the time there was central nervous system invasion, which was invariably fatal. Only two patients survived - both had orbital exenteration, as well as antifungal drug treatment. Invasive fungal sinusitis can, rarely, occur in healthy individuals and should be suspected as a possible cause of a progressive orbital apex syndrome. © 2012 The Authors.

    One hundred consecutive patients receiving related donor kidneys were analyzed in regards to graft and patient survival, morbidity, mortality, histocompatibility and rehabilitation. The average followup was 3 years and 2 months with a minimum post transplant evaluation of one year. Donor morbidity was minimal and the mortality nil. Recipient mortality was 17%, all of which occurred after the first two post transplant months. The most serious life threatening complications after transplantation were due to infection. The greatest morbidity was secondary to aseptic necrosis. The overall graft survival at one year was 94%, 2 years--87%, 3 years--81% and 4 and 5 years--72%. Separation of patients according to tissue typing revealed 95% of recipients with A and B matched kidneys to be alive 5 years later compared to 55% of patients receiving C and D matched kidneys. Rehabilitation was good to excellent in 76% of the living patients and poor in only 4%. These results suggest related donor renal transplantation to be the treatment of choice for patients with chronic renal failure excluding only those individuals who are exceptionally high risks in terms of morbidity and mortality.

    Objective Anterior petrosectomy(AP) was popularized in the 1980s and 1990s as micro-neurosurgery proliferated. Original reports concentrated on the anatomy of the approach and small case series. Recently, with the advent of additional endonasal approaches to the petrous apex, the morbidity of AP remains unclear. This report details approach-related morbidity around and under the temporal lobe. Methods A total of 46 consecutive patients identified from our surgical database were reviewed retrospectively. Results Of the 46 patients, 61% were women. Median age of the patients was 50 years (mean: 48 ± 2 years). Median follow-up of this cohort was 66 months. Most procedures dealt with intradural pathology (n = 40 [87%]). Approach-related morbidity consisted of only two patients (4%) with new postoperative seizures. There were only two significant postoperative hemorrhages (4%). Cerebrospinal fluid leakage occurred in two patients (4%) requiring reoperation. Conclusion Approach-related complications such as seizures and hematoma were infrequent in this series, < 4%. This report describes a contemporary group of patients treated with open AP and should serve as a comparison for approach-related morbidity of endoscopic approaches. Given the pathologies treated with this approach, the morbidity appears acceptable.

    From December 2005 to December 2009, we performed 150 laparoscopic colorectal procedures. Based on this experience, we started offering robot-assisted colorectal surgery from December 2009. This study is a prospective evaluation of consecutive patients in order to study the technical feasibility and oncological outcome of robot-assisted low anterior resection. This investigation was conducted at a single minimal access surgery institute. Between December 2009 and December 2011, 53 consecutive patients with rectal adenocarcinoma underwent a robot-assisted low anterior resection (LAR) or ultralow anterior resection (ULAR) with total mesorectal excision (TME), using the standard da Vinci 'S' model. Patient demographics, mean operative time, mean postoperative hospital stay, blood loss, days to first flatus, resumption of oral feeds, urinary incontinence, and sexual dysfunction were studied. Surgical and pathological outcomes such as quality of TME, free circumferential margins, and number of lymph nodes dissected were also evaluated. Robot docking and undocking times were noted. Of the 53 patients, 41 were men and 12 were women. Their mean age was 66.7 years (range 37-90 years). The ASA grades were distributed as follows: ASA I 15 (28.3 %), ASA II 25 (47.16 %), ASA III 12 (22.64 %), ASA IV 1 (1.88 %). The mean operative time was 180 min (150-230 min) and the mean blood loss was 101.6 ml (50-300 ml). The robot docking time was 10 min (15-25 min) and the undocking time was 5 min (3-10 min). The mean hospital stay was 8 days (7-15 days). None of the patients was converted to either laparoscopic or open procedure. The longitudinal and circumferential margins were negative in all patients. Histopathological reports of 45 patients showed complete TME while 8 patients showed nearly complete TME. No repositioning of the robot was needed for splenic flexure mobilization, thus decreasing the operative time. Along with TME, even the splenic flexure mobilization

    Surgical removal of a symptomatic herniated lumbar disc is performed either with or without the support of a microscope. Up to the time of writing, the literature has reported similar clinical outcomes for the two procedures. Five hundred consecutive patients, operated upon for primary single-level lumbar disc herniation in our University Spine Center between 2003-2011, with (n=275), or without (n=225), the aid of a microscope were included. Data were retrospectively analyzed, comparing the primary endpoint of clinical outcome and the secondary endpoints of complications, surgical time and length of hospitalization. Clinical outcomes and reoperation rates were comparable in both groups. Surgical time was significantly shorter with a mean time of 47minutes without use of the microscope compared to the mean time of 87minutes (plumbar disc herniation is associated with similar clinical outcomes and reoperation rates. Open sequestrectomy is associated with shorter operation times. Microdiscectomy is associated with shorter hospitalization stays.

    AIM: The aim of this study was to assess the usefulness of pre-operative sestamibi-technetium subtraction scintigraphy in a large cohort of patients with primary hyperparathyroidism (HPT). MATERIALS AND METHODS: A group of 156 consecutive patients with biochemically proven HPT underwent sestamibi-technetium subtraction scintigraphy before cervical exploration. Images were interpreted and reported prospectively and influenced the extent of surgical exploration. The intraoperative findings were compared retrospectively with the pre-operative scintigram reports in 154 individuals with technically satisfactory scintigrams. RESULTS: Of the 154 patients with satisfactory scintigrams, 122 (78.2%) demonstrated a single focus of activity following subtraction, 31 (19.9%) had negative findings and the remaining scintigram showed four foci of activity. At operation 138 (89.6%) solitary adenomas were removed, 13 patients (8.4%) had multi-gland disease and in three individuals (2.0%) no abnormal parathyroid tissue was found. The pre-operative scintigram accurately localized 91 of 98 (92.9%) solitary tumours weighing > 500 mg but only 18 of 35 (51.4%) adenomas weighing < 500 mg, (P < 0.0001). Overall sensitivity of sestamibi-technetium scintigraphy for localizing single parathyroid adenomas was 83.7%. CONCLUSION: Sestamibi-technetium subtraction scintigraphy will accurately localize a high proportion of solitary parathyroid adenomas but its usefulness is diminished by its inability to consistently identify smaller tumours.

    In this retrospective study the results of primary and salvage treatment of oropharyngeal carcinoma were evaluated. A total of 289 consecutive patients (103 females and 186 males) were included in the study. Most tumours originated in the tonsil area (58%) and comprised stages I 8%, II 19%, III 46% and IV 28%. The primary treatment was delivered with curative intent in 276 cases (96%). Of these, 266 received primary radiotherapy. The median radiation dose was 62 Gy, given as laterally opposed fields to the primary tumour and bilateral neck. Eight patients were treated with primary surgery and two with chemotherapy as part of a curatively intended treatment programme including radiotherapy. Six patients received palliative treatment, and seven were not treated at all. Out of 276 tumours treated with curative intent, 173 reappeared; 72% recurred in T position, 38% in N position, and 12% at distant metastatic sites, some in combination. Salvage surgery was possible in 52 patients, and 24 treatments were successful. Salvage radiotherapy or cryotherapy was used in 22 patients and 4 were controlled. For the entire group, the 5-year locoregional tumour control, disease-specific survival and overall survival rates were 38%, 44% and 31%, respectively. For patients treated with curative intent, clinical T- and N-stage, stage, tumour size, gender, age, and pretreatment haemoglobin were significant prognostic parameters in a univariate analysis. The Cox multivariate analysis showed that T-stage, N-stage and gender were independent prognostic factors. It is concluded that T-stage, N-stage and gender are significant independent prognostic factors. The primary control of the carcinoma in the T-position is crucial for overall success, but salvage surgery is found to have a favourable success rate in patients suitable for relapse treatment.

    In Lithuania, data on patch testing are lacking and the applicability of the European baseline series needs to be evaluated. The aim of the study was to examine the prevalence of contact allergy to the European baseline series in the population of patients with suspected allergic contact dermatitis in Lithuania. Between April 2006 and October 2008, 816 consecutive adult patients referred to the Department of Skin and Venereal Diseases, Kaunas University of Medicine, with suspected allergic contact dermatitis were patch tested with the European baseline series. Demographic data were collected in accordance with the European Surveillance System on Contact Allergies 'minimal data set'. The positive patch test was observed in 384 (47.4%) patients. The most prevalent contact allergens were nickel sulphate (17.1%), Myroxylon pereirae resin (8.0%), p-phenylenediamine (6.0%), methyldibromo glutaronitrile (5.5%) and colophonium (5.0%). The sex and age factors strongly influenced the prevalence of nickel sensitization. The lowest sensitization prevalences were found to N-isopropyl-N'-phenyl-p-phenylene diamine (0.1%) and 2-mercaptobenzothiazole (0.1%). Differences in the sensitization prevalences to some allergens of the European baseline series compared with other European countries were recognized. The current European baseline series is a suitable diagnostic tool for contact allergy in Lithuania. © 2010 The Authors.

    Full Text Available Background : The association of intraspinal neural anomalies with scoliosis is known for more than six decades. However, there are no studies documenting the incidence of association of intraspinal anomalies in scoliotic patients in the Indian population. The guide lines to obtain an magnetic resonance imaging (MRI scan to rule out neuro-axial abnormalities in presumed adolescent idiopathic scoliosis are also not clear. We conducted a prospective study (a to document and analyze the incidence and types of intraspinal anomalies in different types of scoliosis in Indian patients. (b to identify clinico-radiological ′indicators′ that best predict the findings of neuro-axial abnormalities in patients with presumed adolescent idiopathic scoliosis, which will alert the physician to the possible presence of intraspinal anomalies and optimize the use of MRI in this sub group of patients. Materials and Methods : The data from 177 consecutive scoliotic patients aged less than 21 years were analyzed. Patients were categorized into three groups; Group A - congenital scoliosis (n=60, group B -presumed idiopathic scoliosis (n=94 and group C - scoliosis secondary to neurofibromatosis, neuromuscular and connective tissue disorders (n=23. The presence and type of anomaly in the MRI was correlated to patient symptoms, clinical signs and curve characteristics. Results : The incidence of intraspinal anomalies in congenital scoliosis was 35% (21/60, with tethered cord due to filum terminale being the commonest anomaly (10/21. Patients with multiple vertebral anomalies had the highest incidence (48% of neural anomalies and isolated hemi vertebrae had none. In presumed ′idiopathic′ scoliosis patients the incidence was higher (16% than previously reported. Arnold Chiari-I malformation (AC-I with syringomyelia was the most common neural anomaly (9/15 and the incidence was higher in the presence of neurological findings (100%, apical kyphosis (66.6% and early

    2010-11-01

    Full Text Available Abstract Background Femoral access is a fundamental element of catheter-based cerebral angiography. Knowledge of location of the common femoral artery (CFA bifurcation is important as the risk of retroperitoneal bleeding is increased if the puncture is superior to the inguinal ligament and there is an increased risk of thrombosis and arteriovenous fistula formation if the puncture is distal into branch vessels. We sought to characterize the location of the CFA bifurcation along with the presence of significant atherosclerosis or iliac tortuosity in a contemporary series of subarachnoid hemorrhage (SAH patients. Findings The records of a prospective single-center aneurysm database were reviewed to identify 100 consecutive SAH patients. Using an oblique femoral arteriogram, the presence of significant atherosclerosis, iliac tortuosity, and the CFA bifurcation were assessed. The CFA bifurcation was graded according to its position with respect to the femoral head: below (grade 1, lower half (grade 2, and above the upper half (grade 3. We found a CFA bifurcation grade 1 in 50 patients (50%, mean age 51.2 years, grade 2 in 40 patients (40%, mean age 55.5 years, and grade 3 in 10 patients (10%, mean age 58.2 years. Whereas 30 of 90 patients with CFA grades I or II were male (33%, only 10% with grade 3 were male (1 of 10, p = 0.12. Mean age for significant atherosclerosis was 65.5 +/- 2.6 years versus 50.9 +/- 1.6 years (p Conclusions Although a requisite element of endovascular treatment in SAH patients, femoral access can be complicated by a high common femoral artery bifurcation and the presence of atherosclerotic disease and/or iliac artery tortuosity. In this study, we found a grade 3 (above the femoral head CFA bifurcation in 10% patients, with 90% of these patients being female. We also found the presence of atherosclerotic disease and iliac tortuosity to be significantly more likely in patients older than 65 years of age.

    The objectives of this retrospective study were to elucidate the clinicopathological features and recent surgical results of cervical esophageal cancer. Cervical esophageal cancer has been reported to have a dismal prognosis. Accurate knowledge of the clinical characteristics of cervical esophageal cancer is warranted to establish appropriate therapeutic strategies. The clinicopathological features and treatment results of 63 consecutive patients with cervical esophageal cancer (Ce group) who underwent surgical resection from 1980 to 2013 were analyzed and compared with 977 patients with thoracic or abdominal esophageal cancer (T/A group) who underwent surgical resection during that time. Among the patients who received curative resection, the 5-year overall and disease-specific survival rates of the Ce patients were significantly better than those of the T/A patients (overall: 77.3% vs 46.5%, respectively, P = 0.0067; disease-specific: 81.9% vs 55.8%, respectively, P = 0.0135). Although total pharyngo-laryngo-esophagectomy procedures were less frequently performed in the recent period, the rate of curative surgical procedures was markedly higher in the recent period (2000-1013) than that in the early period (1980-1999) (44.4% vs 88.9%, P = 0.0001). The 5-year overall survival rate in the recent period (71.5%) was significantly better than that in the early period (40.7%, P = 0.0342). Curative resection for cervical esophageal cancer contributes to favorable outcomes compared with other esophageal cancers. Recent surgical results for cervical esophageal cancer have improved, and include an increased rate of curative resection and decreased rate of extensive surgery.

    Spinal stab wounds presenting with retained knife blades (RKB) are uncommon, often resulting in spinal cord injury (SCI) with catastrophic neurological consequences. The purpose of this study is to report a single unit's experience in management of this pattern of injury at this regional referral centre. Retrospective review of medical records identified 51 consecutive patients with spinal stabs presenting with a RKB at the Neurosurgery Department at Inkosi Albert Luthuli Central Hospital between January 2003 and February 2015. The data was analyzed for patient characteristics, level of the RKB, neurological status using the ASIA impairment scale, associated injuries, radiological investigations, management, hospital length of stay, complications and mortality. The mean age was 28±10.9 years (range 14-69), with 45 (88%) males (M: F=7.5:1). The median Injury Severity Score was 16 (range 4-26). RKB were located in the cervical [9,18%], thoracic [38,74%], lumbar [2,4%] and sacral [2,4%] spine. Twelve patients (24%) sustained complete SCI (ASIA A), while 21 (41%) had incomplete (ASIA B, C, D), of which 17 had features of Brown-Sequard syndrome. Eighteen (35%) patients were neurologically intact (ASIA E). There were 8 (16%) associated pneumothoraces and one vertebral artery injury. Length of hospital stay was 10±7.1 days (range 1-27). One patient (2%) died during this period. Stab injuries to the spine presenting with RKB are still prevalent in South Africa. Resources should be allocated to prevention strategies that decrease the incidence of inter-personal violence. All RKBs should be removed in the operating theatre by experienced surgeons to minimise complications. Copyright © 2015 Elsevier Ltd. All rights reserved.

    Discogenic lumbosciatica is a common disorder in patients between 30 and 40 years old. Because of the frequency and socio-professional impact of this entity, it represents a real public health problem. DiscoGel® is a class III medical device used for nucleolysis to avoid discectomy. The goal of this study was to evaluate the effectiveness of this treatment in patients with discogenic lumbosciatica following unsuccessful conservative medical treatment. This is a retrospective, single-center study including 25 patients who were treated with DiscoGel® between 2010 and 2011 at Niort Hospital, France. The severity of lumbar and radicular pain was assessed by a verbal numeric scale (VNS) and patient satisfaction. Patients were classified as successes or failures. Treatment was found to reduce the severity of lumbar pain in 73% and of radicular pain in 80% of patients in the success group. Treatment was a failure in 64% of patients. A comparison of the two groups showed that a preoperative MODIC 2 MRI signal of the adjacent vertebral end plate was significantly associated with treatment failure (Chi(2)=8572, P lumbosciatica in 16 patients. These results do not support others in the literature. A lack of statistical power could partly explain these results. The most important result of this study is found in the subgroup analysis which suggests that indications for DiscoGel® treatment could be modified in the future in relation to preoperative imaging data. 4.

    To report cytopathological observations on the cells retrieved from the 25-G cannula used during prognostic transvitreal fine-needle aspiration biopsy of choroidal melanoma. Transvitreal fine-needle aspiration biopsy of choroidal melanoma was performed through a 25-G valved cannula. Twenty samples from 20 consecutive patients were obtained. Most tumors were treated with plaque radiation therapy (16/20, 80%) following standard clinical guidelines. Four enucleated globes (4/20, 20%) were subjected to a similar transvitreal biopsy before enucleation. Cytopathological analysis of the cells retrieved from the cannula revealed the absence of any cells in 4 of 20 samples (20%). In the remaining 16 samples, definite melanoma cells and atypical cells (probable melanoma cells) were observed in 2 samples each (total 4, 25%). Histiocytes (4/16, 25%) and lymphocytes (1/16, 6%) were also observed. Thirteen samples (13/16, 81%) contained conjunctival epithelial epithelium. Prognostication could be performed on all fine-needle aspiration biopsy samples (20, 100%). Use of a 25-G valved cannula offers potential advantages by isolating the needle tract and by allowing retrieval of the contaminating cells without affecting the prognostic yield of the fine-needle aspiration biopsy sample.

    The functional integrity of the floor of the mouth (FOM) is essential in maintaining tongue mobility, deglutition, and control and disposal of saliva. The present study focused on reporting oral function using functional intraoral Glasgow scale (FIGS) in patients who had surgical ablation and reconstruction of FOM carcinoma with or without chemo-radiotherapy. The study included patients who had surgical treatment of floor of mouth cancer in two regional head and neck units in Glasgow, UK between January 2006 and August 2007. Patients were assessed using FIGS before surgery, 2 months, 6 months and 1 year after surgery. It is a five-point scale self-questionnaire to allow patients to self-assess speech, chewing and swallowing. The maximum total score is 15 points. The influence of socio-demographic parameters, tumour characteristics and surgical parameters was addressed in the study. A total of 62 consecutive patients were included in the study; 41 (66.1 %) were males and 21 (33.9 %) were females. The patients' mean age at the time of diagnosis was 60.6 years. Fifty (80.6 %) patients had unilateral origin of FOM tumours and 10 (19.4 %) had bilateral origin. Peroral approach was the most common approach used in 35 (56.4 %) patients. The mean preoperative FIGS score was 14. Two months after surgery, it droped to 9.4 then started to increase gradually thereafter and recorded 10.1 at 6 months and 11 at 1 year. Unilateral FOM resection recorded better score than bilateral and lateral FOM tumours than anterior at 1 year postoperatively. Furthermore, direct closure showed better functional outcome than loco-regional and free flaps. The FIGS is a simple and comprehensive way of assessing a patient's functional impairment following surgery in the FOM. Tumour site and size, surgical access, surgical resection and method of reconstruction showed significant influence on oral function following surgical resection. A well-designed rehabilitation programme is required to improve

    Full Text Available Aim : We report the outcome analysis of retropubic radical prostatectomy (RRP performed in 428 patients in terms of pathological findings, complications, and survival. Materials and Methods : Systematically recorded case reports forms of consecutive 428 RRPs done over a 14-year period were analyzed using the SPSS 14 software. Secondary analysis was done to evaluate era specific (pre and post 2002 changes in clinical features and survivals. Results : Seven-year overall survival (OAS, cancer-specific survival (CSS, and event-free survival (EFS was 83.2%, 82.8%, and 69.8% respectively in our series. Era-specific survival showed higher CSS post 2002, and there was an increase in presentation with organ-confined disease. Univariate and multivariate analysis showed statistically significant impact on era specific outcome. With the improvement in techniques decrease in complications rate and increase in quality of life was noted. Conclusions : Our series spanning over decade demonstrates that RRP is viable option to offer cure to organ-confined carcinoma prostate. Further, there is evidence of stage migration and improvements in outcome in post 2002 patients. Although our series is modest in number, the success rates and outcome data matches those reported in the literature.

    Full Text Available Background: There is little information about the possible influence of lifestyle and etiologic risk factors on survival amongst patients with gastric cancer. Methods: We recruited a consecutive series of 249 patients with definite diagnosis of gastric cancer who had been hospitalized in Towhid Hospital, Sanandaj, Kurdistan Province in Western Iran during a five-year period from 2006 until 2011. Survival rate was calculated according to the Kaplan-Meier and log rank statistical methods. Cox hazard regression was used to investigate the effect of the variables and adjust for the effect of age. Results: According to univariate analysis, related variables that included age, gender, Residence, histology grade, histology type, familial history of gastrointestinal cancer and mental illness during the disease had no significant effects on survival rate variation. Significant independent factors on survival included past medical history of gastrointestinal diseases (P-value = 0.010, tobacco smoking (P-value = 0.012, and early diagnosis (P-value = 0.008. Cox-regression analysis of demographic, lifestyle and histological factors with >45 years of age as the reference revealed that patients 46-65 years of age at diagnosis (HR=0.602; 95% CI=0.250-1.44; P=0.256 and those >66 years of age (HR=1.07, 95% CI=0.46-2.50, P≤0.001 had an increased risk for disease progression and death. Conclusions: Past medical history of gastrointestinal diseases, tobacco smoking and early stage diagnosis might influence the long-term survival of patients with gastric cancer.

One hundred and twenty-five years of the Annals of Botany Part 1: the first 50 years (1887-1936). Annals of Botany 115: : 1-18] summarized events leading to its founding, highlighted the individuals involved and examined the Journal's achievements and management practices over the first 50 years to 1937. This second article covers the next 75 years. The account draws principally on the Journal's own records, minute books, financial accounts, original letters and notes held by the Annals of Botany Company, the Journal's owners and managers. In 1937, its 51st year, the Journal was re-launched as Annals of Botany New Series and its volume numbers were reset to No. I. The present article evaluates the evolution of the New Series up to 2012, Annals of Botany's 125th anniversary year. The period includes a 2-year run-up to World War II, six war years and their immediate aftermath, and then on through increasingly competitive times. The ebb and flow of the Journal's fortunes are set against a roll-call of the often highly distinguished scientists who managed and edited the Journal. The article also examines an internal crisis in the 1980s that radically altered the Journal's organization in ways that were, ultimately, to its benefit. The narrative is set against changes to economic conditions in Great Britain over the period, to the evolving nature and geographical distribution of much experimental plant science and to the digital revolution that, from the late 20th century, transformed the workings of Annals of Botany and of scientific publishing more generally. © The Author 2016.

    Introduction: Gastro-duodenal perforations may be suspected in patients with history of ulceration, who present with acute pain and abdominal wall rigidity, but radiological findings in these cases may be unable to confirm a clinical diagnosis. The aim of our study was to report our experience in the diagnosis of gastro-duodenal perforation by conventional radiography, US and CT examinations. Material and methods: We retrospectively reviewed medical records of 166 consecutive patients who presented in the last 2 years to our institutions with symptoms of acute abdomen and submitted to surgery at the Emergency Unit of the ''A.Cardarelli'' Hospital of Naples with a surgical finding of perforated gastro-duodenal ulcer. The evidence of free intraperitoneal air on abdominal plain film was considered as a direct or suggestive finding of perforation. Evidence of intraperitoneal free fluid and/or reduced intestinal peristalsis at sonographic examination were considered indirect signs of gastro-duodenal perforation. Evidence of free peritoneal gas at CT was considered as a direct evidence of gastro-duodenal perforation. Results: Twenty patients underwent immediate surgery with no preoperative imaging evaluation, in 10 of them the site of perforation was found in a juxta-pyloric region and in the others at level of duodenum. In 146 patients submitted to serial radiological investigations before surgery, the site of perforation was in 56 (38.3%) duodenal, in 52 (35.6%) juxta-pyloric, in 28 (19.1%) gastric and in 10 (6.8%) pyloric. The cause of perforation was in all cases gastric or duodenal ulceration, in seven cases involving pancreatic parenchyma. In 110 (75.4%) patients with direct findings of perforation, in 94 cases (85.5%) the correct diagnosis was established on abdominal plain film, in two (1.8%) with radiographic and sonographic examinations and in 14 (12.7%) on CT findings. In 36 (24,6%) patients with no direct findings of perforation, only 24

    Background Short-segment U-shaped pedicle screw fixation has been widely used to treat thoracolumbar burst fracture.Some studies have reported the disadvantages of traditional U-shaped pedicle screw,which included a relatively high rate of adjacent segment degeneration and screw failure,including screw pullout and breakage.The purpose of this study was to assess the efficacy of open reduction and fixation using KumaFix fixation system in treatment of thoracolumbar burst fractures.Methods From June 2011 to June 2012,45 consecutive patients with thoracolumbar burst fractures were enrolled.They were randomly assigned to treatment with KumaFix (the treatment group,n=23) or traditional U-shaped pedicle screw (the control group,n=22).The patients were followed up postoperatively and were assessed with regard to radiologic and clinical outcomes.Radiologic outcomes were assessed mainly on the basis of Cobb angle and vertebral wedge angle.Clinical outcomes were evaluated mainly with use of Visual Analog Scale (VAS) for pain and the Oswestry Disability Index (ODI) Questionnaire.Results All patients were followed up from 9 to 22 months.There were no significant differences between the two groups with regard to preoperative indices.The operation time in the treatment group was significantly lower than that in the control group.Preoperative Cobb angles and vertebral wedge angles in two groups were significantly decreased after surgery,and these have been well maintained at the last follow-up with mild correction losses.The results of clinical outcome showed lower VAS and ODI scores in two groups compared with those preoperative,and the treatment group had greater improvement on the ODI compared with the control group at the last follow-up.Conclusions Compared with traditional U-shaped pedicle screw,KumaFix fixation system can achieve gradual,controlled reduction,provide enough space for bone implantation,and avoid acceleration of adjacent segment degeneration.It is an effective

    Full Text Available Klinefelter syndrome (KS is a hypergonadotropic hypogonadism characterized by a 47, XXY karyotype. The risk of testicular cancer in KS is of interest in relation to theories about testicular cancer etiology generally; nevertheless it seems to be low. We evaluated the need for imaging and serum tumor markers for testicular cancer screening in KS. Participants were 40 consecutive KS patients, enrolled from December 2009 to January 2013. Lactate dehydrogenase (LDH, alpha-fetoprotein (AFP, and beta-human chorionic gonadotrophin subunit (β-HCG serum levels assays and testicular ultrasound (US with color Doppler, were carried out at study entry, after 6 months and every year for 3 years. Abdominal magnetic resonance (MR was performed in KS when testicular US showed micro-calcifications, testicular nodules and cysts. Nearly 62% of the KS had regular testicular echotexture, 37.5% showed an irregular echotexture and 17.5% had micro-calcifications and cysts. Eighty seven percent of KS had a regular vascular pattern, 12.5% varicocele, 12.5% nodules 1 cm. MR ruled out the diagnosis of cancer in all KS with testicular micro calcifications, nodules and cysts. No significant variations in LDH, AFP, and β-HCG levels and in US pattern have been detected during follow-up. We compared serum tumor markers and US pattern between KS with and without cryptorchidism and no statistical differences were found. We did not find testicular cancer in KS, and testicular US, tumor markers and MR were, in selected cases, useful tools for correctly discriminating benign from malignant lesions.

    Neoplasms of histiocytic and dendritic cells are rare disorders of the lymph node and soft tissues. Because of this rarity, the corresponding biology, prognosis and terminologies are still being better defined and hence historically, these disorders pose clinical and diagnostic challenges. These disorders include Langerhans cell histiocytosis (LCH), histiocytic sarcoma (HS), follicular dendritic cell sarcoma (FDCS), interdigtating cell sarcoma (IDCS), indeterminate cell sarcoma (INDCS), and fibroblastic reticular cell tumors (FRCT). In order to gain a better understanding of the biology, diagnosis, and treatment in these rare disorders we reviewed our cases of these neoplasms over the last twenty five years and the pertinent literature in each of these rare neoplasms. Cases of histiocytic and dendritic cell neoplasms diagnosed between 1989–2014 were identified using our institutional database. Thirty two cases were included in this analysis and were comprised of the following: Langerhans cell histiocytosis (20/32), histiocytic sarcoma (6/32), follicular dendritic cell sarcoma (2/32), interdigitating dendritic cell sarcoma (2/32), indeterminate dendritic cell sarcoma (1/32), and fibroblastic reticular cell tumor (1/32). Median overall survival was not reached in cases with LCH and showed 52 months in cases with HS, 12 months in cases with FDCS, 58 months in cases with IDCS, 13 months in the case of INDCS, and 51 months in the case of FRCT. The majority of patients had surgical resection as initial treatment (n = 18). Five patients had recurrent disease. We conclude that histiocytic and dendritic cell neoplasms are very rare and perplexing disorders that should be diagnosed with a combination of judicious morphology review and a battery of immunohistochemistry to rule out mimics such as carcinoma, lymphoma, neuroendocrine tumors and to better sub-classify these difficult to diagnose lesions. The mainstay of treatment for localized disease remains surgical resection

    To assess the feasibility and accuracy of two magnetic resonance (MR) venography methods in a consecutive series of patients with suspected deep vein thrombosis of the upper extremity (DVTUE). Consecutive in- and outpatients who were referred for imaging of suspected DVTUE in a large teaching hospital during the period April 2001 to October 2002 were eligible for inclusion. All patients were scheduled to undergo contrast venography with the intention to perform additional MR venography. Both time-of-flight and gadolinium-enhanced 3D MR venography were scheduled. All MR imaging were interpreted independently by consensus of two experienced radiologists, who were blinded for contrast venography outcome. Patients were managed based on contrast venography only. A total of 44 patients were eligible for inclusion. Thirteen patients were excluded (5 refused consent, 2 inability to gain venous access, 2 renal failure, 4 logistic reasons). Contrast venography was performed in 31 patients, and demonstrated DVTUE in 11 patients. MR imaging was not feasible in 10 patients (4 unable to lie flat, 3 claustrophobia, 1 too large for MR scanner, 1 osteosynthesis of shoulder, 1 pacemaker). The sensitivity and specificity of TOF MRV versus Gadolinium 3D MRV was 71% and 89% versus 50% and 80%, respectively. A high number of patients were unable to undergo MR venography in this setting. Contrast-enhanced MRV did not improve diagnostic accuracy. The clinical utility of MR venography in the setting of suspected DVTUE seems disappointing.

    Transmissible strains of Pseudomonas aeruginosa have been described for cystic fibrosis (CF) and may be associated with a worse prognosis. Using a comprehensive strain biobank spanning 3 decades, we sought to determine the prevalence and stability of chronic P. aeruginosa infection in an adult population. P. aeruginosa isolates from sputum samples collected at initial enrollment in our adult clinic and at the most recent clinic visit were examined by a combination of pulsed-field gel electrophoresis and multilocus sequence typing and compared against a collection of established transmissible and local non-CF bronchiectasis (nCFB) isolates. A total of 372 isolates from 107 patients, spanning 674 patient-years, including 66 patients with matched isolates from initial and final encounters, were screened. A novel clone with increased antibacterial resistance, termed the prairie epidemic strain (PES), was found in 29% (31/107 patients) of chronically infected patients referred from multiple prairie-based CF centers. This isolate was not found in those diagnosed with CF as adults or in a control population with nCFB. While 90% (60/66 patients) of patients had stable infection over a mean of 10.8 years, five patients experienced strain displacement of unique isolates, with PES occurring within 2 years of transitioning to adult care. PES has been present in our cohort since at least 1987, is unique to CF, generally establishes chronic infection during childhood, and has been found in patients at the time of transition of patients from multiple prairie-based CF clinics, suggesting broad endemicity. Studies are under way to evaluate the clinical implications of PES infection.

    The aim of this study was to evaluate the value of thyroglobulin (Tg) kinetics during preparation of radioiodine ablation for prediction of initial radioiodine ablation failure in thyroid cancer patients. Thyroid cancer patients after total thyroidectomy who underwent radioiodine ablation with 3–4 weeks of hormone withdrawal between May 2011 and January 2012 were included. Consecutive serum Tg levels 5–10 days before ablation (Tg1) and on the day of ablation (Tg2) were obtained. The difference between Tg1 and Tg2 (ΔTg), daily change rate of Tg (ΔTg/day) and Tg doubling time (Tg-DT) were calculated. Success of initial ablation was determined by the results of the follow-up ultrasonography, diagnostic radioiodine scan and stimulated Tg level after 6 to 20 months. A total of 143 patients were included. Failed ablation was reported in 52 patients. Tg2 higher than 5.6 ng/ml and Tg-DT shorter than 4.2 days were significantly related to a high risk of ablation failure. ΔTg and ΔTg/day did not show significant correlation with ablation failure. Thyroglobulin kinetics on consecutive blood sampling during hormone withdrawal may be helpful in predicting patients with higher risk of treatment failure of initial radioiodine ablation therapy in thyroid cancer patients.

    Neuroblastoma is an aggressive pediatric tumor accounting for ~15% of cancer-associated mortalities in children. Despite the current intensive therapy, >50% of high-risk patients experience tumor relapse or regrowth caused by the activation of minimal residual disease (MRD). Although several MRD detection protocols using various reverse transcription-quantitative polymerase chain reaction (RT-qPCR) markers have been reported to evaluate the therapeutic response and disease status of neuroblastoma patients, their clinical significance remains elusive. The present study reports two high-risk neuroblastoma patients, whose MRD was consecutively monitored using 11 RT-qPCR markers (CHRNA3, CRMP1, DBH, DCX, DDC, GABRB3, GAP43, ISL1, KIF1A, PHOX2B and TH) during their course of treatment. The two patients initially responded to the induction therapy and reached MRD-negative status. The patients' MRD subsequently became positive with no elevation of their urinary homovanillic acid, urinary vanillylmandelic acid and serum neuron-specific enolase levels at 13 or 19 weeks prior to the clinical diagnosis of tumor relapse or regrowth. The present cases highlight the possibility of consecutive MRD monitoring using 11 markers to enable an early detection of tumor relapse or regrowth in high-risk neuroblastoma patients.

    Deep sternal incisional surgical site infection is a serious and potentially life-threatening complication after open heart surgery. Although a rare post-operative complication, the rates of post-operative morbidity and mortality are greater in patients who develop a deep sternal incisional surgical site infection than in those who do not. We evaluated retrospectively the results of patients who developed a deep sternal incisional surgical site infection who were treated with either a pectoralis major flap or delayed primary closure after previous negative-pressure wound therapy (NWPT). From July 2007 to July 2012, 25 patients had a deep sternal incisional surgical site infection after open heart surgery in the Departments of Plastic Surgery and Cardiac Surgery of the Tri-Service General Hospital Medical Center. Sternal refixation was not performed in our patients. In 15 patients, a unilateral or bilateral pectoralis major advancement flap with a myocutaneous or muscle flap was used. In seven patients, delayed primary closure was performed after NPWT. One patient received a rectus abdominis myocutaneous flap and another received a free anterior lateral thigh flap. One patient died after developing nosocomial pneumonia with severe sepsis after debridement. In our series, no patient required sternal re-fixation. Our findings suggest that delayed primary closure and use of a unilateral or bilateral pectoralis major flap following NPWT for a deep sternal incisional surgical site infection are simple and quick methods for managing such difficult surgical incisions even if the deep sternal surgical site infection is located in the lower one-third of the sternum.

    Slow pathway modification (SPM) is the therapy of choice for AV-nodal reentry tachycardia (AVNRT). When AVNRT is not inducible, empirical ablation can be considered, however, the outcome in patients with two AV nodal echo beats (AVNEBs) is unknown. Out of a population of 3003 patients who underwent slow pathway modification at our institution between 1993 and 2013, we retrospectively included 32 patients with a history of symptomatic tachycardia, lack of paroxysmal supraventricular tachycardia (pSVT) inducibility but occurrence of two AVNEBs. pSVT documentation by electrocardiography (ECG) was present in 20 patients. The procedural endpoint was inducibility of less than two AVNEBs. This was reached in 31 (97%) patients. Long-term success was assessed by a telephone questionnaire (follow-up time 63±9 months). A total 94% of the patients benefited from the procedure (59% freedom from symptoms; 34% improvement in symptoms). Among those patients in whom ECG documentation was not present, 100% benefited (58% freedom from symptoms, 42% improvement). This is the first collective analysis of a group of patients presenting with symptoms of pSVT and inducibility of only two AVNEBs. Procedural success and clinical long-term follow-up were in the range of the reported success rates of slow pathway modification of inducible AVNRT, independent of whether ECG documentation was present. Thus, SPM is a safe and effective therapy in patients with two AVNEBs. Copyright © 2016. Published by Elsevier Ltd.

    Cystic dystrophy of heterotopic pancreas, groove pancreatitis, pancreatic hamartoma of the duodenum, paraduodenal wall cyst, and myoadenomatosis are all terms grouped together, from a pathological viewpoint, as definitions of paraduodenal pancreatitis (PP). The objective of the present study was to investigate the clinical characteristics, therapeutic strategies, and results in 58 patients undergoing pancreatic resection for PP. From January 1990 to December 2006 data were prospectively collected on 58 patients who were diagnosed with PP who then underwent pancreaticoduodenectomy. In this patient cohort the median age was 44.7 years; only 4 patients were women, and only 3 had non-drinker and/or non smoker habits. The overall morbidity was 18.9%, and the median hospitalization was 11 days. There were no postoperative deaths. In a median follow-up of 96.3 months, all patients noted a decrease in the pain associated with PP; 35 patients (76%) had complete disappearance of pain, whereas occasional relapsing pain occurred in the remaining 11 (24%). Patients with PP have clinical characteristics similar to those of chronic pancreatitis. The diagnostic imaging modalities of choice are ultrasonographic endoscopy and magnetic resonance cholangiopancreaticography. Based on our surgical experience, pancreaticoduodenectomy seems to be a reasonable choice of treatment in patients with PP.

    Heart transplantation (HTx) is a well-established treatment for severe cardiac failure. However, HTx for cardiac sarcoidosis is rare; less than 80 patients have been reported worldwide. In many patients, the diagnosis was not made prior to HTx. The aim of this study was to describe the use of HTx...... to HTx. In three patients, all with dilated cardiomyopathy due to myocardial sarcoidosis, the final diagnosis was obtained by examination of the explanted heart. Arrythmias (supraventricular and ventricular), heart block, mitral valve insufficiency and dilated cardiomyopathy were prominent clinical...... features. None of the patients had recurrence of sarcoid disease in the allograft. Two patients are long-term survivors and two are deceased, one of primary graft failure, the other from Cytomegalovirus myocarditis.

    We report five consecutive cases of Anaplasma (A.) phagocytophilum infection (the causative agent of human granulocytic anaplasmosis (HGA)) from western Austria. All infections were acquired between June and August in 2003 and 2004 in the Inn valley (Tyrol, Austria). Four patients required hospitalisation, one patient was treated as an outpatient. During the acute stage of illness, laboratory findings included thrombocytopenia (5/5), elevated C-reactive protein (5/5), elevated neopterin (5/5), elevated lactate dehydrogenase (4/5), and elevation of liver enzymes (4/5). Leukopenia (3/5) and elevated procalcitonin (2/5) were less frequently observed. All patients were treated with tetracyclines, which led to prompt improvement of the clinical conditions. Anti-platelet antibodies were observed in one of four patients, but remained unchanged after complete covalescence.

    Full Text Available Abstract Background Refusal of heterogenic blood products can be for religious reasons as in Jehovah's Witnesses or otherwise or as requested by an increasing number of patients. Furthermore blood reserves are under continuous demand with increasing costs. Therefore, transfusion avoidance strategies are desirable. We describe a historic comparison and current results of blood saving protocols in Jehovah's Witnesses patients. Methods Data on 250 Jehovah's Witness patients operated upon between 1991 and 2003 (group A were reviewed and compared with a second population of 250 patients treated from 2003 to 2012 (group B. Results In group A, mean age was 51 years of age compared to 68 years in group B. An iterative procedure was performed in 13% of patients in group B. Thirty days mortality was 3% in group A and 1% in group B despite greater operative risk factors, with more redo, and lower ejection fraction in group B. Several factors contributed to the low morbidity-mortality in group B, namely: preoperative erythropoietin to attain a minimal hemoglobin value of 14 g/dl, warm blood cardioplegia, the implementation of the Cornell University protocol and fast track extubation. Conclusions Cardiac surgery without transfusion in high-risk patients such as Jehovah Witnesses can be carried out with results equivalent to those of low risk patients. Recent advances in surgical techniques and blood conservation protocols are main contributing factors.

    Background: Septic arthritis in the sternoclavicular (SC) region is rare and may be difficult to diagnose clinically and radiologically. It mainly affects immunocompromised persons, and can clinically be misinterpreted as tumor and rheumatic disorders. Lacking radiological reference standard, a multimodality approach may contribute to a prolonged diagnostic process. Purpose: To describe the diagnostics of septic arthritis in the SC region. Material and Methods: Between 2001 and 2011, 10 patients with Staphylococcus infection in the SC region were investigated in our institution. Clinical, biochemical, radiological, and microbiological findings were studied retrospectively; all CT and MR examinations were re-evaluated. Results: Initial radiography in nine patients and ultrasonography in six patients were inconclusive resulting in supplementary MRI and/or CT. Five patients examined by MRI were immediately diagnosed with septic arthritis whereas CT in five patients led to the diagnosis in only one. Three were subsequently diagnosed by MRI, but delayed more than 2.5 weeks, and one was diagnosed by surgery. The median time to diagnosis was 1.5 weeks. The delay caused by imaging was 0 days to 11.5 weeks (median 0 days). By re-evaluation overlooked complications included mediastinitis in seven patients (three diffuse, four localized), and abscesses and pleuritis each in four patients. Conclusion: Awareness of infection in the SC region is important to avoid diagnostic delay. MRI is proposed as the initial imaging procedure.

    Mucosal proctectomy with ileoanal pull-through in the treatment of ulcerative colitis and familial polyposis provides a technique for the preservation of the anal sphincters and relatively normal mechanisms of continence. Five patients had straight ileoanal anastomosis while 18 had the construction of a J-pouch. A two-team approach was used for simultaneous abdominal and perineal procedures to facilitate a shortened operating time. A loop ileostomy was routinely used in the postoperative period and was closed an average of 4.5 months (range: 2-16 months) later without complication. Prolonged preoperative hospitalization was rarely necessary and outpatient steroid enema preparation was routinely used. There were no deaths. Nineteen patients with functioning pull-through procedures have been followed an average of 23 months (range: 3-42 months). Two other patients have not had ileostomy closure because of complications. The two remaining patients had intractable diarrhea and have since undergone conversion to a permanent ileostomy. The 19 patients are continent, having three to nine bowel movements each day. Nearly all wear a perineal sanitary pad because of rare, unpredictable leakage of small amounts of fluid, especially at night. Complications were significant in this group of patients. Intestinal obstruction was a frequent problem, occurring in 52 per cent of the entire series and necessitating reoperation in 22 per cent. Anal stricture was a problem in another five patients. A variety of other minor problems occurred and most were treated nonoperatively. In spite of moderate diarrhea and occasional leakage of stool, all patients with functioning pull-through procedures prefer their current status to life with an ileostomy.(ABSTRACT TRUNCATED AT 250 WORDS)

    Full Text Available INTRODUCTION: Male testosterone deficiency is associated with bad sexual function and quality of life (QoL. The aim of this study was to determine whether a daily dose of 25 mg clomiphene citrate (CC is effective in stimulating the endogenous testosterone production pathway and to address the applicability of this medication as a therapeutic option for symptomatic hypogonadism. MATERIALS AND METHODS: This was a prospective study. Men with low sexual desire and testosterone levels (T below 400 ng/dL were selected to receive CC. Blood samples were obtained to determine baseline measurements of serum T, estradiol, LH, lipid profile and fasting plasma glucose. Each patient was treated with a daily dose of 25 mg CC for at least 3 months. Patients were asked if they experienced any side effects related to the use of CC and if they experienced any improvement in their sexual profile. Paired samples T-test was utilized to analyze responses to therapy. RESULTS: Our cohort consisted of 125 men with hypogonadism and low libido. Mean age was 62 years (± 11.1 years. Serum T levels ranged from 309 ng/dL (baseline, mean value to 642 ng/dL (3 months after CC initiation, mean value (p < 0.001. Serum cholesterol levels ranged from 197 to 186 mg/dL (p = 0.003. There were no statistically significant differences when comparing pre and post-treatment HDL-Cholesterol, triglycerides, fasting plasma glucose and prolactin. All men reported improvements in the post-treatment QoL scores. No serious adverse events were recorded. CONCLUSIONS: The CC was effective in stimulating the endogenous production of testosterone. A lower level of total cholesterol was verified after three months of treatment. This medication should be considered as a therapeutic option for some patients with symptomatic male testosterone deficiency.

    In order to assess the cognitive and adaptive profiles of school-aged patients with Dravet syndrome (DS), we proposed to evaluate the intelligence and adaptive scores in twenty-one 6- to 10-year-old patients with DS followed in our institution between 1997 and 2013. Fourteen patients were tested using the Wechsler Intelligence Scale for Children (WISC) and the Vineland Adaptive Behavioral Scales (VABS); 6 patients could not be tested with the WISC and were tested with the VABS only, and one was tested with the WISC only. Data regarding the epilepsy were retrospectively collected. Statistical analysis (Spearman rank order and Pearson correlation coefficient) was used to correlate early epilepsy characteristics with the cognitive and adaptive scores. Sodium channel, neuronal alpha-subunit type 1 (SCN1A) was mutated in 19 out of 21 patients. After the age of 6years, none of the DS patients had a normal intelligence quotient (IQ) using WISC (age at the testing period: mean=100±5; median=105months; mean total IQ=47±3; n=15). Only five patients had a verbal and/or a non verbal IQ of more than 60 (points). Their cognitive profile was characterized by an attention deficit, an inability to inhibit impulsive responses, perseverative responses and deficit in planning function. Administering the Vineland Adaptive Behavioral Scales in the same period, we showed that socialization skills were significantly higher than communication and autonomy skills (age at the testing period: mean=100±4; median=100months; n=20). We did not find any significant correlation between the IQ or developmental quotient assessed between 6 and 10years of age and the quantitative and qualitative parameters of epilepsy during the first two years of life in this small group of patients. Despite an overall moderate cognitive deficit in this group of patients, the Vineland Adaptive Behavioral Scales described an adaptive/behavioral profile with low communication and autonomy capacities, whereas the

    The purpose of this study was to assess the use of the Günther Tulip Filter (GTF) for the management of venous thromboembolism (VTE). Between December 2000 and April 2005, 118 patients (42 males, 76 females; mean age 60.5 years) diagnosed with VTE, underwent treatment with a GTF. The filter was left permanently in 52 patients. In the other 66 patients, attempts were made to retrieve it, with success in 60 cases (90.9%). No major complication was found throughout the filter's use. Of the 58 patients with the permanent filters, 41 underwent enhanced computed tomography at follow-up in the chronic phase. Thirty-eight filters (92.7%) remained patent, and under low-intensity anticoagulation therapy (international normalized ratio 1.8+/-0.4), the patency rate was 97.1%. Penetration of the inferior vena cava (IVC) wall by the filter's struts beyond a distance of 3 mm occurred in 23 patients (56.1%), but there was no observable leakage from the IVC or injury to adjacent organs. The GTF is feasible and safe for treating VTE. When used permanently, GTFs have a high patency rate, and there is neither leakage from the IVC nor injury to adjacent organs in the event of penetration by the struts.

    OBJECTIVE Patients treated for Chiari I malformation (CM-I) with posterior fossa decompression (PFD) may occasionally and unpredictably develop postoperative hydrocephalus. The clinical risk factors predictive of this type of Chiari-related hydrocephalus (CRH) are unknown. The authors' objective was to evaluate their experience to identify risk factors that may predict which of these patients undergoing PFD will develop CRH after surgery. METHODS The authors performed a retrospective clinical chart review of all patients who underwent PFD surgery and duraplasty for CM-I at the Primary Children's Hospital in Utah from June 1, 2005, through May 31, 2015. Patients were dichotomized based on the need for long-term CSF diversion after PFD. Analysis included both univariate and multivariable logistic regression analyses. RESULTS The authors identified 297 decompressive surgeries over the period of the study, 22 of which required long-term postoperative CSF diversion. On multivariable analysis, age < 6 years old (OR 3.342, 95% CI 1.282-8.713), higher intraoperative blood loss (OR 1.003, 95% CI 1.001-1.006), and the presence of a fourth ventricular web (OR 3.752, 95% CI 1.306-10.783) were significantly associated with the need for long-term CSF diversion after decompressive surgery. CONCLUSIONS Younger patients, those with extensive intraoperative blood loss, and those found during surgery to have a fourth ventricular web were at higher risk for the development of CRH. Clinicians should be alert to evidence of CRH in this patient population after PFD surgery.

    AIM: To analyze the importance in predicting patients risk of mortality due to upper gastrointestinal (UGI)bleeding under today's therapeutic regimen.METHODS: From 1998 to 2001, 121 patients with the diagnosis of UGI bleeding were treated in our hospital.Based on the patients' data, a retrospective multivariate data analysis with initially more than 270 single factors was performed. Subsequently, the following potential risk factors underwent a logistic regression analysis:age, gender, initial hemoglobin, coumarines, liver cirrhosis, prothrombin time (PT), gastric ulcer (small curvature), duodenal ulcer (bulbus back wall), Forrest classification, vascular stump, variceal bleeding, MalloryWeiss syndrome, RBC substitution, recurrent bleeding,conservative and surgical therapy.RESULTS: Seventy male (58%) and 51 female (42%)patients with a median age of 70 (range: 21-96) years were treated. Their in-hospital mortality was 14%. While 12% (11/91) of the patients died after conservative therapy, 20% (6/30) died after undergoing surgical therapy. UGI bleeding occurred due to duodenal ulcer (n = 36; 30%), gastric ulcer (n = 35; 29%), esophageal varicosis (n = 12; 10%), Mallory-Weiss syndrome (n = 8; 7%), erosive lesions of the mucosa (n = 20;17%), cancer (n = 5; 4%), coagulopathy (n = 4; 3%),lymphoma (n = 2; 2%), benign tumor (n = 2; 2%)and unknown reason (n = 1; 1%). A logistic regression analysis of all aforementioned factors revealed that liver cirrhosis and duodenal ulcer (bulbus back wall)were associated risk factors for a fatal course after UGI bleeding. Prior to endoscopy, only liver cirrhosis was an assessable risk factor. Thereafter, liver cirrhosis,the location of a bleeding ulcer (bulbus back wall) and patients' gender (male) were of prognostic importance for the clinical outcome (mortality) of patients with a bleeding ulcer.CONCLUSION: Most prognostic parameters used in clinical routine today are not reliable enough in predicting a patient's vital threat posed by

    Hereditary spherocytosis is an inherited hemolytic anemia caused by a deficiency in erythrocyte membrane proteins. Removal of the spleen may reduce the intra-splenic hemolytic process of the disease and, therefore, may correct the anemia. Furthermore, it seems to decrease the levels of serum bilirubin, thus reducing the formation of gallbladder stones. Indications and timing of splenectomy, however, are still debated. Twelve patients with severe hereditary spherocytosis operated on with laparoscopic splenectomy were retrospectively reviewed. Median age at diagnosis was 13.8 years (range 8-25 years). Male to female ratio was 5/7. Indications for laparoscopic removal of the spleen included anemia unresponsive to iron supplementation in eight patients (66.6 %) with increase need for red cells transfusions, and jaundice with symptoms related to cholelitiasis in four patients (33.3 %). Laparoscopic splenectomy was associated in four cases to laparoscopic cholecystectomy. Mean operative time was 50 min (range 40-75 min) with no conversion to open surgery. Mean hospital stay ranged from 3 to 7 days. In a 16-month follow-up, no complications were recorded and a persistent correction of anemia was observed. With the advent of laparoscopic surgery, splenectomy has been performed by this mini-invasive approach in referral centers. Laparoscopic splenectomy is an effective technique, when performed in patients with hereditary spherocytosis. Low complication rate and persistent correction of the hematologic disorders can be expected after the laparoscopic splenectomy, provided that a proper technique is performed and an experienced surgical team is available.

    Fibromyalgia is a chronic widespread pain disorder in which, the neurogenic origin of the pain, featured by allodynia and hyperalgesia, results from an imbalance in the levels of neurotransmitters and consequently of the peripheral pro- and anti-inflammatory mediators. Whole body cryotherapy is a peculiar physical therapy known to relieve pain and inflammatory symptoms characteristics of rheumatic diseases, through the regulation of the cytokine expression. The aim of this study was to qualitatively evaluate the effects of cryotherapy on the clinical output of fibromyalgic patients. A total of 100 fibromyalgic patients (age range 17-70 years) were observed; 50 subjects were addressed to cryotherapy, while the second group (n = 50) did not underwent to the cryotherapic treatment. All subjects kept the prescribed pharmacological therapy during the study (analgesic and antioxidants). The referred health status pre- and post-observation was evaluated with the following scales: Visual Analogue Scale, Short Form-36, Global Health Status and Fatigue Severity Scale. Fibromyalgic patients treated with cryotherapy reported a more pronounced improvement of the quality of life, in comparison with the non-cryo treated fibromyalgic subjects, as indicated by the scores of the qualitative indexes and sub-indexes, that are widely recognized tools to assess the overall health status and the effect of the treatments. We speculate that this improvement is due to the known direct effect of cryotherapy on the balance between pro- and anti-inflammatory mediators having a recognized role in the modulation of pain.

    The aim of this study was to evaluate the results of the initial and salvage treatment for hypopharyngeal carcinoma. The study was conducted in 1963 to 1991 and included 138 patients (38 females and 100 males). Most of the tumours originated in the piriform sinus (86%). Tumour stage distribution was T1: 20%, T2: 27%, T3: 37% and T4: 17% and nodal stage distribution was N0: 45%, N1: 25%, N2: 10%, and N3: 20%. Primary treatment was delivered with curative intent in 124 out of 138 cases. Treatment failure was noted in 98 patients, with 55% recurrence in T-position, 39% in N-position, and 14% at distant metastases sites. Salvage surgery was successful in 9 out of 32 patients. The overall 5-year locoregional tumour control, cause-specific and overall survival rates were 20%, 25% and 19%, respectively. Univariate actuarial analysis showed that T- and N-stage, clinical stage, tumour size and well-differentiated tumours were significant prognostic parameters. A Cox multivariate analysis showed that only the T- and N-stages were independent prognostic factors. In conclusion, the prognosis for advanced hypopharyngeal carcinoma is extremely poor and the meagre results with conventional radiotherapy alone indicate that other treatment modalities should be introduced in the management of this disease.

    Hypersexuality remains an increasingly common but poorly understood patient complaint. Despite diversity in clinical presentations of patients referred for hypersexuality, the literature has maintained treatment approaches that are assumed to apply to the entire phenomenon. This approach has proven ineffective, despite its application over several decades. The present study used quantitative methods to examine demographic, mental health, and sexological correlates of common clinical subtypes of hypersexuality referrals. Findings support the existence of subtypes, each with distinct clusters of features. Paraphilic hypersexuals reported greater numbers of sexual partners, more substance abuse, initiation to sexual activity at an earlier age, and novelty as a driving force behind their sexual behavior. Avoidant masturbators reported greater levels of anxiety, delayed ejaculation, and use of sex as an avoidance strategy. Chronic adulterers reported premature ejaculation and later onset of puberty. Designated patients were less likely to report substance abuse, employment, or finance problems. Although quantitative, this article nonetheless presents a descriptive study in which the underlying typology emerged from features most salient in routine sexological assessment. Future studies might apply purely empirical statistical techniques, such as cluster analyses, to ascertain to what extent similar typologies emerge when examined prospectively.

The favorable 12- and 36-month outcomes for frontal lobe epilepsy surgery are 62% and 52%, respectively. For both parietal and occipital epilepsy lobe surgeries the 12- and 36-month outcomes are 67%. For multilobar epilepsy surgery, the 12- and 36-month outcomes are 65% and 50%, respectively. The 12- and 36-month outcomes for functional hemispherectomy epilepsy surgery are 64.2% and 63%, respectively. According to histopathology diagnosis, mesiotemporal sclerosis (MTS and benign CNS tumors had the best favorable outcome after surgery at 1 year (77.27% and 84.3%, resp., and 3 years (76% and 75%, resp.,. The least favorable seizure-free outcome after 3 years occurred in cases with dual pathology (66.6%. Thirty-four epilepsy patients with normal magnetic resonance imaging (MRI brain scans were surgically treated. The first- and third-year epilepsy surgery outcome of 17 temporal lobe surgeries were (53% and (47% seizure-free, respectively. The first- and third-year epilepsy surgery outcomes of 15 extratemporal epilepsy surgeries were (47% and (33% seizure-free. Conclusion. The best outcomes are achieved with temporal epilepsy surgery, mesial temporal sclerosis, and benign CNS tumor. The worst outcomes are from multilobar surgery, dual pathology, and normal MRI.

    Conclusion: This surgical procedure, like laparoscopic treatment, allows the surgeon to avoid dissection of the abdominal layer and improves prosthesis adhesion with reinforcement of the incisional area near the abdominal defect. The reduction in operation time is remarkable. Despite good results in terms of safety and minimal recurrence for laparoscopy in the management of IH, the use of minimally invasive techniques for large incisional wall defects, especially in elderly patients, is still controversial and practiced by few surgeons. This open technique avoids cardiopulmonary complications arising from pneumoperitoneum in the elderly.

    Pallidal stimulation is a convincing and valid alternative for primary generalized dystonia refractory to medical therapy or botulinum toxin. However, the clinical outcome reported in literature is variable most likely because of heterogeneity DBS techniques employed and /or to clinical dystonic pattern of the patients who undergo surgery. In this study, we report the long term follow up of a homogeneous group of eleven subjects affected by segmental dystonia who were treated with bilateral stimulation of the Globus Pallidus pars interna (GPi) from the years 2000 to 2008. All the patients were evaluated, before surgery and at 6-12-24-36 months after the treatment, in accordance with the Burke Fahn Marsden Dystonia Rating Scale (BFMDRS). Our study indicates that DBS promotes an early and significant improvement at 6 months with an even and a better outcome later on. The analysis of specific sub items of the BFMDRS revealed an earlier and striking benefit not only as far as segmental motor function of the limbs but also for the complex cranial functions like face, (eyes and mouth), speech and swallowing, differently from results reported in primary generalized dystonia. Deep Brain Stimulation of GPi should be considered a valid indication for both generalized and segmental dystonia when other therapies appear ineffective.

    We found no prospective studies on dental extraction in anticoagulated patients in the literature, even though most authors suggest that there is no need to change anticoagulant treatment and to utilize a local haemostatic measure after extraction. In the present study, we have verified the incidence of bleeding complications after dental extraction in a group of 250 consecutive anticoagulated patients. Two hundred and fifty non-anticoagulated subjects requiring dental extraction represented the control group. In all patients, anticoagulant treatment was not changed (International Normalized Ratio, 1.8-4) and local haemostatic measures (fibrin sponge, silk suture and a gauze saturated with tranexamic acid) were used. All procedures were performed in an outpatient clinic setting. We registered four bleeding complications in the group of anticoagulated patients and three in the control group. The difference of bleeding complications in the two groups was not statistically different (relative risk, 1.14; 95% confidence interval, 0.29-6.04; P = 0.7). None of the post-operative late bleeding required hospitalization and/or blood transfusions, and further local measures were sufficient to stop the bleeding. The protocol proposed in the present study makes dental extractions in anticoagulated patients possible on an outpatient basis with a cost reduction for the community and minor discomfort for the patients.

    Purpose: The present study was performed to analyze the midterm results (five consecutive patients, 2-year follow-up) of the endovascular management of visceral artery aneurysms using the Cardiatis Multilayer Flow Modulator (CMFM) (Cardiatis, Isnes, Belgium), a self-expandable stent. Materials and Methods: From August 2009 to January 2011, we implanted five CMFMs in five patients (all men; mean age 73 years) to treat two common hepatic artery aneurysms, one celiac trunk aneurysm, one splenic artery aneurysm, and one superior mesenteric artery aneurysm (diameter 25-81 mm). The primary end point was technical success. The secondary end point was stent patency, absence of aneurysm rupture or reperfusion, and shrinking of the sac at 6-, 12-, and 24-month follow-up using computed tomography angiography. Follow-up ranged from 24 to 48 months (mean 31.2). Results: Technical success was achieved in all patients. Complete exclusion of the aneurysm with sac shrinking was achieved in two patients. Two stents became occluded at 6- and 24-month follow-up, respectively; both patients were asymptomatic and were not retreated. One patient developed sac reperfusion due to incomplete aneurysm exclusion. Conclusion: Long-term results in a wider population are needed to validate the effectiveness of the CMFM.

    Fifty children with Ewing's sarcoma were consecutively treated from 1962 to 1987 and retrospectively analyzed at the I.P.O.F.G. of Lisbon. At first diagnosis, 10 cases had distant metastases. The remaining 40 patients had clinically localized disease, and different protocols were followed over the years. The best results were obtained with chemotherapy and radiotherapy with or without surgery; and for these children the two-year survival rate was 42.8% vs. 8.3% for the group of patients submitted to local treatment alone. Besides the treatment modality, other factors influenced the prognosis, such as inflammatory signs, sex, tumor volume, and tumor site as well as evidence of distant metastases.

    The low-phospholipid-associated cholelithiasis syndrome (LPAC; OMIM 171060) is a peculiar form of intrahepatic cholelithiasis occurring in young adults, associated with ABCB4/MDR3 gene sequence variations. Our aim was to determine the genotype-phenotype relationships in 156 consecutive patients with the criteria of LPAC syndrome. A variant was detected in 79 (61 missense and 18 truncating sequence variants), 63 being monoallelic. The clinical features (age at onset, high prevalence in women, frequency and severity of acute and chronic complications, intrahepatic cholestasis of pregnancy [ICP]) were similar in the patients with or without ABCB4 gene sequence variation. Truncating variations were associated with an earlier onset of symptoms both in women and men. Acute and chronic biliary complications were variant-independent. Half of the women who had pregnancy developed ICP. The frequency of ICP and fetal complications were similar in patients with missense and truncating variants. The LPAC syndrome is more frequent in women and highly associated with ICP. Half of the patients harbored missense or truncating variants of the ABCB4 gene. The characteristics of the patients without detectable variant are similar to those with variant, indicating that yet unexplored regions of the ABCB4 and other genes may be involved. © 2013 by the American Association for the Study of Liver Diseases.

    Full Text Available Abstract Background Kyphoplasty represents an established minimal-invasive method for correction and augmentation of osteoporotic vertebral fractures. Reliable data on perioperative and postoperative complications are lacking in the literature. The present study was designed to evaluate the incidence and patterns of perioperative complications in order to determine the safety of this procedure for patients undergoing kyphoplasty. Patients and Methods We prospectively enrolled 102 consecutive patients (82 women and 20 men; mean age 69 with 135 operatively treated fractured vertebrae who underwent a kyphoplasty between January 2004 to June 2006. Clinical and radiological follow-up was performed for up 6 months after surgery. Results Preoperative pain levels, as determined by the visual analogous scale (VAS were 7.5 +/- 1.3. Postoperative pain levels were significantly reduced at day 1 after surgery (VAS 2.3 +/- 2.2 and at 6-month follow-up (VAS 1.4 +/- 0.9. Fresh vertebral fractures at adjacent levels were detected radiographically in 8 patients within 6 months. Two patients had a loss of reduction with subsequent sintering of the operated vertebrae and secondary spinal stenosis. Accidental cement extravasation was detected in 7 patients in the intraoperative radiographs. One patient developed a postoperative infected spondylitis at the operated level, which was treated by anterior corporectomy and 360 degrees fusion. Another patient developed a superficial wound infection which required surgical revision. Postoperative bleeding resulting in a subcutaneous haematoma evacuation was seen in one patient. Conclusion The data from the present study imply that percutaneous kyphoplasty can be associated with severe intra- and postoperative complications. This minimal-invasive surgical procedure should therefore be performed exclusively by spine surgeons who have the capability of managing perioperative complications.

  15. The Incidence of Patent Foramen Ovale in 1,000 Consecutive Patients: A Contrast Transesophageal Echocardiography Study

    1995-01-01

    Study objective: Patent foramen ovale (PFO) is present in 10 to 35% of people and has been reported to be an important risk factor for cardioembolic cerebrovascular accidents (CVAs) and transient ischemic attacks (TIAS), especially in younger patients. While contrast transthoracic echocardiography has been used to detect PFO, contrast transesophageal echocardiography (TEE) has a greater sensitivity. Prior studies reported the incidence of PFO in patients presenting with a CVA or TIA. Design: To determine the incidence of PFO in a more general population, we reviewed 1,000 consecutive TEES performed with contrast and color Doppler for the presence of PFO and other cardioembolic risk factors, including atrial septal aneurysm (ASA), aortic plaque, atrial fibrillation (AFib), and atrial thrombi. While imaging with monoplane or biplane TEE, multiple injections of agitated saline solution were injected during cough or Valsalva maneuver to detect flow through a PFO. Patients: There were 482 male and 518 female patients with mean age of 60 + 17 years (range 11 to 93 years). Results: Patent foramen ovale was found in 9.2% of all patients and, though seen in all age groups divided by decade, the incidence in patients aged 40 to 49 years was greater than those aged 70 to 79 years (12.96% vs 6.15%',, p=0.03). Contrast TEE had a much higher detection rate than color Doppler alone. Importantly, there was no greater incidence of PFO in patients with CVA vs thos without CVA, or in male vs female patients. Also, there was a very strong correlation between the presence of ASA and PFO (p<.001). Conclusion: Thus, PFO detected by TEE, frequently seen with ASA, is seen in all age groups and does not in itself present a risk factor for CVA. The association of PFO with peripheral thrombosis and CVA needs further study.

    The study was conducted to evaluate the frequencies of the anatomic variations and the gender distributions of these variations of the pancreatic duct and their relevance with the Cambridge classification system as morphological sign of chronic pancreatitis using magnetic resonance cholangiopancreatography (MRCP). We retrospectively reviewed 1312 consecutive patients who referred to our department for MRCP between January 2013 and August 2015. We excluded 154 patients from the study because of less than optimal results due to imaging limitations or a history of surgery on pancreas. Finally a total of 1158 patients were included in the study. Among the 1158 patients included in the study, 54 (4.6%) patients showed pancreas divisum, 13 patients (1.2%) were defined as ansa pancreatica. When we evaluated the course of the pancreatic duct, we found the prevalence 62.5% for descending, 30% for sigmoid, 5.5% for vertical and 2% for loop. The most commonly observed pancreatic duct configuration was Type 3 in 528 patients (45.6%) where 521 patients (45%) had Type 1 configuration. Vertical course (p = 0.004) and Type 2 (p = 0.03) configuration of pancreatic duct were more frequent in females than males. There were no statistically significant differences between the gender for the other pancreatic duct variations such as pancreas divisium, ansa pancreatica and course types other than vertical course (p > 0.05 for all). Variants of pancreas divisum and normal pancreatic duct variants were not associated with morphologic findings of chronic pancreatitis by using the Cambridge classification system. The ansa pancreatica is a rare type of anatomical variation of the pancreatic duct, which might be considered as a predisposing factor to the onset of idiopathic pancreatitis.

    Full Text Available Epidemiological studies of neuromyelitis optica (NMO in Jamaica are lacking. Here we reviewed the clinical records of 700 patients undergoing neurological evaluation at the Kingston Public Hospital, the largest tertiary institution in Jamaica over a 4 month period. We investigated the diagnostic utility of Aquaporin-4 ImmuneglobulinG (AQP4-IgG testing in 36 consecutive patients with a diagnosis of an inflammatory demyelinating disorder (IDD of the central nervous system (CNS. Patients were classified into 3 categories: i NMO, n=10; ii multiple sclerosis (MS, n=14 and iii unclassified IDD (n=12. All sera were tested for AQP-IgG status by cell binding assay (Euroimmun. No MS cases were positive. Ninety per cent of NMO cases were positive. Four of 12 patients with unclassified IDD tested positive for AQP4-IgG. AQP4-IgG seropositivity was associated with a lower socioeconomic status, higher EDSS (P=0.04 and lower pulmonary function than the seronegative cases (P=0.007. Aquaporin-4 autoimmunity may account for a significant proportion of Jamaican CNS IDDs.

    The goal of this study was to compare the semen parameters of two successive samples obtained within an interval of less than 60 minutes from patients planning to undergo intrauterine insemination (IUI) whose first samples exhibited low semen quality. Thirty-two consecutive patients were enrolled in the study. On the day of IUI, the semen analysis of the samples initially presented by all patients met at least two of the following criteria: sperm concentration <5×10(6)/mL, total sperm count <10×10(6), progressive sperm motility (a+b) in the native sample <30%, and total motile sperm count (TMSC) <4×10(6). A successive semen sample was obtained no more than 60 minutes after the first sample. Compared to the first sample, the second exhibited significantly (p<0.05) improved sperm concentration, TMSC, progressive motility, and vitality. Regarding TMSC, the most critical parameter on the day of IUI, 23 patients (71.8%) improved it, while nine (28.2%) displayed poorer outcomes. In defined cases, requesting a second successive ejaculate on the day of insemination may result in a high percentage of cases in an improvement of the quality of the sample.

    The objectives of this study are to assess: (a) the prevalence of vitamin D deficiency among new patients attending rheumatology outpatient departments, (b) the age profile of these low vitamin D patients and (c) whether any diagnostic category had a particularly high number of vitamin D-deficient patients. All new patients seen consecutively in general rheumatology clinics between January to June 2007 inclusive were eligible to partake in this study, and 231 out of 264 consented to do so. Parathyroid hormone, 25-hydroxyvitamin D, creatinine, calcium, phosphate, albumin and alkaline phosphatase levels were measured. We defined vitamin D deficiency as <\\/=53 nmol\\/l and severe deficiency as <\\/=25 nmol\\/l. Overall, 70% of 231 patients had vitamin D deficiency, and 26% had severe deficiency. Sixty-five percent of patients aged >\\/=65 and 78% of patients aged <\\/=30 years had low vitamin D levels. Vitamin D deficiency in each diagnostic category was as follows: (a) inflammatory joint diseases\\/connective tissue diseases (IJD\\/CTD), 69%; (b) soft tissue rheumatism, 77%; (c) osteoarthritis, 62%; (d) non-specific musculoskeletal back pain, 75% and (e) osteoporosis, 71%. Seasonal variation of vitamin D levels was noted in all diagnostic groups apart from IJD\\/CTD group, where the degree of vitamin D deficiency persisted from late winter to peak summer. Very high prevalence of vitamin D deficiency was noted in all diagnostic categories (p = 0.006), and it was independent of age (p = 0.297). The results suggest vitamin D deficiency as a possible modifiable risk factor in different rheumatologic conditions, and its role in IJD\\/CTD warrants further attention.

    This prospective study aimed to compare outcomes after laparoscopic peritoneal lavage (LPL) and sigmoid resection with primary colorectal anastomosis (RPA). From June 2010 to June 2015, 40 patients presenting with Hinchey III peritonitis from perforated diverticulitis underwent LPL or RPA. Patients with Hinchey II or IV peritonitis and patients who underwent an upfront Hartmann procedure were excluded. Primary endpoint was overall 30-day or in-hospital postoperative morbidity after surgical treatment of peritonitis. Twenty-five patients underwent RPA and 15 LPL. Overall postoperative morbidity and mortality rates were not significantly different after RPA and LPL (40 vs 67 %, p = 0.19; 4 vs 6.7 %, p = 1, respectively). Intra-abdominal morbidity and reoperation rates were significantly higher after LPL compared to RPA (53 vs 12 %, p < 0.01; 40 vs 4 %, p = 0.02, respectively). Multivariate analysis showed that LPL (p = 0.028, HR = 18.936, CI 95 % = 1.369-261.886) was associated with an increased risk of postoperative intra-abdominal septic morbidity. Among 6 patients who underwent reoperation after LPL, 4 had a Hartmann procedure. All surviving patients who had a procedure requiring stoma creation underwent stoma reversal after a median delay of 92 days after LPL and 72 days after RPA (p = 0.07). LPL for perforated diverticulitis is associated with a high risk of inadequate intra-abdominal sepsis control requiring a Hartmann procedure in up to 25 % of patients. RPA appears to be safer and more effective. It may represent the best option in this context.

    AimTo present our single-centre prospective experience on the use of cryoablation (CA) applied to treat primary breast cancer (BC) in a cohort of patients unsuitable for surgical treatment.Materials and MethodsTwenty-three consecutive post-menopausal female patients (median age 85 years; range 56–96) underwent percutaneous CA of unifocal, biopsy-proven BC, under ultrasound/computed tomography (US/CT) guidance. Clinical and dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) follow-ups were systematically scheduled at 3, 12, 18 and 24 months. Local tumour control was assessed by comparing baseline and follow-up DCE-MRI.ResultsTwenty-three BC (median size 14 mm) were treated under local anaesthesia (78.3 %) or local anaesthesia and conscious sedation (21.7 %). Median number of cryo-probes applied per session was 2.0. A “dual-freezing” protocol was applied for the first ten patients and a more aggressive “triple-freezing” protocol for the remaining 13. Median follow-up was 14.6 months. Five patients recurred during follow-up and two were successfully re-treated with CA. Five patients presented immediate CA-related complications: four hematomas evolved uneventfully at 3-month follow-up and one skin burn resulted in skin inflammation and skin retraction at 3 and 12 months, respectively.ConclusionsPercutaneous CA is safe and well tolerated for non-resected elderly BC patients. Procedures can be proposed under local anaesthesia only. Given the insulation properties of the breast gland, aggressive CA protocols are required. Prospective studies are needed to better understand the potential role of CA in the local treatment of early BC.

    Full Text Available To determine the pattern of lower gastrointestinal disease in the Eastern region of Saudi Arabia we analysed 1907 colorectal biopsies obtained from 1590 consecutive patients (1256 males &334 females, evaluated during a 13 year period (1983-1996 in a tertiary care teaching hospital. The age range was 6-81 years with a mean of 37 + 15. During the same period 6874 new patients were seen in the Gastroenterology Clinics. Saudi Arabs constituted 970 (61 % of all patients. The remaining 620 (39% were non-Saudi, mostly of Arab origin from neighbouring countries. The most common presenting symptom for referral was abdominal pain (1193 patients, 75% followed by diarrhea (636 patients, 40%. The most frequent histologic diagnosis was a normal mucosa followed by non specific proctocolitis accounting respectively for 37.9% and 37.4% of all cases. These were followed by schistosomiasis, 113 (7.1%, adenocarcinoma, 91 (5.7% and ulcerative colitis, 91 cases with a relative frequency of 5.7% and a calculated prevalence of 1.3%. Of significance was the encounter of 14 cases of Crohn′s disease amounting to 0.9% of all cases with a calculated prevalence of 0.2%. A minority of 83 patients (5.2% were cases of either a benign polyp, diverticular disease, tuberculosis, ischaemia, lymphoma, pseudomembranous colitis (PMC, eosinophilic gastroenteritis or malacoplakia. These data show that although a "normal mucosa" and "nonspecific proctocolitis" were the dominant diagnoses, significantly, ulcerative colitis and Crohn′s disease exist and should be considered in the differential diagnosis of lower GI disease.

    Schwannoma of the cervical vagus nerve is rare. Treatment options include intracapsular enucleation and en bloc resection. The purpose of this study was to compare the outcomes of enucleation and resection in terms of postoperative mortality and morbidity, freedom from vocal cord palsy, freedom from local recurrence, quality-adjusted life-year (QALY) and vocal handicap index (VHI). Twentytwo consecutive patients were divided into two groups. Patients in group A (n = 9) underwent intracapsular enucleation, whereas patients in Group B (n = 13) underwent en bloc resection. Main endpoints of the study were postoperative mortality and morbidity, freedom from vocal cord palsy, freedom from local recurrence and quality of life. The quality of life after surgery was assessed according to the quality-adjusted life-year (QALY) EQ-5D-5L methodology, and calculation of the voice handicap index (VHI). Postoperative mortality was nil. Morbidity included 1 wound dehiscence in group A and 2 transitory dysphagias in group B. Freedom from vocal cord palsy was 22% in group A and zero in group B (p = 0.15). Operation-specific local recurrence rate was 33% (3/9 patients) in group A and nil in group B (0/23 patients) (p = 0.05). QALYs was 0.55 in group A and 0.54 in group B (p = 1.0). VHI was 23.77 in group A and 26.15 in group B (p = 1.00). Resection is superior to enucleation in terms of freedom from local recurrence. Functional results are comparable for both techniques.

    Introduction In this cephalometric investigation, we analyzed the treatment effects of bone-anchored maxillary protraction (BAMP) with miniplates in the maxilla and mandible connected by Class III elastics in patients with Class III malocclusion. Methods The treated sample consisted of 21 Class III patients consecutively treated with the BAMP protocol before the pubertal growth spurt (mean age, 11.10 ± 1.8 years) and reevaluated after BAMP therapy, about 1 year later. The treated group was compared with a matched control group of 18 untreated Class III subjects. Significant differences between the treated and control groups were assessed with independent-sample t tests (P<0.05). Results Sagittal measurements of the maxilla showed highly significant improvements during active treatment (about 4 mm more than the untreated controls), with significant protraction effects at orbitale and pterygomaxillare. Significant improvements of overjet and molar relationship were recorded, as well as in the mandibular skeletal measures at Point B and pogonion. Vertical skeletal changes and modifications in incisor inclination were negligible, except for a significant proclination of the mandibular incisors in the treated group. Significant soft-tissue changes reflected the underlying skeletal modifications. Conclusions Compared with growth of the untreated Class III subjects, the BAMP protocol induced an average increment on skeletal and soft-tissue advancement of maxillary structures of about 4 mm, and favorable mandibular changes exceeded 2 mm.

    The purpose of this study was to evaluate the clinical feasibility of coronary artery imaging during routine preoperative 64-slice MDCT scans of the chest. Ninety-nine consecutive patients in sinus rhythm underwent a biphasic multidetector-row spiral CT examination of the chest without the administration of beta-blockers, including an ECG-gated acquisition over the cardiac cavities, followed by a non-gated examination of the upper third of the thorax. Data were reconstructed to evaluate coronary arteries and to obtain presurgical staging of the underlying disease. The percentage of assessable segments ranged from 65.4% (972/1,485) when considering all coronary artery segments to 88% (613/693) for the proximal and mid segments, reaching 98% (387/396) for proximal coronary artery segments. The 387 interpretable proximal segments included 97 (97%) LM, 99 (100%) LAD, 96 (97%) LCX and 95 (96%) RCA with a mean attenuation of 280.70{+-}52.93 HU. The mean percentage of assessable segments was significantly higher in patients with a heart rate {<=}80 bpm (n=48) than in patients with a heart rate greater than 80 bpm (n=35) (80{+-}11% vs. 72{+-}13%; P=0.0008). Diagnostic image quality was achieved in all patients for preoperative staging of the underlying disorder. The mean estimated effective dose was 12.06{+-}3.25 mSv for ECG-gated scans and 13.88{+-}3.49 mSv for complete chest examinations. Proximal and mid-coronary artery segments can be adequately evaluated during presurgical CT examinations of the chest obtained with 64-slice MDCT without the administration of {beta}-blockers.

    Objectives: To investigate the diagnostic accuracy of 64-slice multidetector computed tomography (64-CT) for detection of in-stent restenosis (ISR) in an unselected, consecutive patient population. Background: Detection of in-stent restenosis by cardiac CT would be a major advance for the evaluation of patients suspected of having ISR. However, the diagnostic accuracy of current generation 64-CT in this context is not fully established. Methods: We conducted a prospective study on patients with stable angina or acute coronary syndrome with no prior history of coronary artery disease. Six months after percutaneous coronary intervention (PCI) with stent placement they underwent a 64-CT scan (Toshiba Multi-Slice Aquilion 64) and consequently a repeat coronary angiography for comparison. Cardiac CT data sets were analyzed for the presence of in-stent restenosis by two independent expert readers blinded to the coronary angiographic data. Results: Ninety-three patients with a total of 140 stents were evaluated. Males comprised 82% of the study group and the mean age was 63 {+-} 10 years. The mean time from PCI to the repeat coronary angiography was 208 {+-} 37 days and the mean time from 64-CT to repeat coronary angiography was 3.7 {+-} 4.9 days. The restenosis rate according to coronary angiography was 26%. Stent diameter, strut thickness, heart rate and body mass index (BMI) significantly affected image quality. The sensitivity, specificity, positive and negative predictive values of 64-CT for detection of in-stent restenosis were 27%, 95%, 67% and 78%, respectively. Conclusions: Current generation, 64-slice CT, remains limited in its ability to accurately detect in-stent restenosis.

    Thoracolumbar instrumentation has experienced a dramatic increase in utilization over the last 2 decades. However, pedicle screw fixation remains a challenging undertaking, with suboptimal placement contributing to postoperative pain, neurological deficit, vascular complications, and return to the operating suite. Image-guided spinal surgery has substantially improved the accuracy rates for these procedures. However, it is not without technical challenges and a learning curve for novice operators. The authors present their experience with the O-arm intraoperative imaging system and share the lessons they learned over nearly 5 years. The authors performed a retrospective chart review of 270 consecutive patients who underwent thoracolumbar pedicle screw fixation utilizing the O-arm imaging system in conjunction with StealthStation navigation between April 2009 and September 2013 at a single tertiary care center; 266 of the patients underwent CT scanning on postoperative Day 1 to evaluate hardware placement. The CT scans were interpreted prospectively by 3 neuroradiologists as part of standard work flow and retrospectively by 2 neurosurgeons and a senior resident. Pedicle screws were evaluated for breaches according to the 3-tier classification proposed by Mirza et al. Of 270 patients, 266 (98.5%) were included in the final analysis based on the presence of a postoperative CT scan. Overall, 1651 pedicle screws were placed in 266 patients and yielded a 5.3% breach rate; 213 thoracic and 1438 lumbosacral pedicle screws were inserted with 6.6% and 5.1% breach rates, respectively. Of the 87 suboptimally placed screws, there were 13 Grade 1, 16 Grade 2, and 12 Grade 3 misses as well as 46 anterolateral or "tip-out" perforations at L-5. Four patients (1.5%) required a return to the operating room for pedicle screw revision, 2 of whom experienced transient radicular symptoms and 2 remained asymptomatic. Interestingly, the pedicle breach rate was higher than anticipated at 13

    Background Coronary artery fistulas (CAFs) are rare congenital abnormality often unintentionally found in patients with coronary artery disease.Clinical diagnosis of CAFs is difficult due to symptomless or lack of specific symptoms.Dual-source computed tomography (DSCT) might be a useful diagnostic tool for CAFs.The study aimed to retrospectively summarize the imaging features of CAFs delineated at DSCT in 48 CAF patients detected from consecutive 6624 patients with suspected or confirmed coronary artery disease in our institution.Methods Forty-eight patients underwent DSCT angiography by using retrospective electrocardiographic (ECG) gating after infusion of 70 ml of intravenous contrast material during breath hold.Maximum intensity projection (MIP),curved planar reconstruction (CPR),and volume rendering technique (VR) were obtained.Anomalous termination of coronary artery in each subject was evaluated by two radiologists (with more than 10 years experience with cardiovascular imaging),and disagreement between diagnosis readers was settled by a consensus reading.Ten of 48 patients also underwent traditional coronary angiography (CAG) simultaneously.Results In each CAF case,DSCT angiography clearly demonstrated the origin,the termination,the size of abnormal vessel and its course in relation to surrounding great vessels.CAF arising from right coronary artery was the most common type,left circumflex was the least one involved among three coronaries,and pulmonary artery was the most common drainage site.Aneurismal fistulous tract,coronary atherosclerosis,myocardial bridging and anomalous origin of coronary artery were also detected in this group.The demonstration of drainage sites in CAG was consistent with DSCT angiography in 9 patients,and judgment on one anomalous connection in CAG was inconsistent with that in DSCT angiography.Conclusions DSCT angiography could provide accurate delineation of anomalous communications,size and numbers of fistulas in patients with

    To evaluate direct medical costs and their predictors in patients with refractory epilepsy enrolled into the SOPHIE study (Study of Outcomes of PHarmacoresistance In Epilepsy) in Italy. Adults and children with refractory epilepsy were enrolled consecutively at 11 tertiary referral centers and followed for 18 months. At entry, all subjects underwent a structured interview and a medical examination, and were asked to keep records of diagnostic examinations, laboratory tests, specialist consultations, treatments, hospital admissions, and day-hospital days during follow-up. Study visits included assessments every 6 months of seizure frequency, health-related quality of life (Quality of Life in Epilepsy Inventory 31), medication-related adverse events (Adverse Event Profile) and mood state (Beck Depression Inventory-II). Cost items were priced by applying Italian tariffs. Cost estimates were adjusted to 2013 values. Of 1,124 enrolled individuals, 1,040 completed follow-up. Average annual cost per patient was € 4,677. The highest cost was for antiepileptic drug (AED) treatment (50%), followed by hospital admissions (29% of overall costs). AED polytherapy, seizure frequency during follow-up, grade III pharmacoresistance, medical and psychiatric comorbidities, and occurrence of status epilepticus during follow-up were identified as significant predictors of higher costs. Age between 6 and 11 years, and genetic (idiopathic) generalized epilepsies were associated with the lowest costs. Costs showed prominent variation across centers, largely due to differences in the clinical characteristics of cohorts enrolled at each center and the prescribing of second-generation AEDs. Individual outliers associated with high costs related to hospital admissions had a major influence on costs in many centers. Refractory epilepsy is associated with high costs that affect individuals and society. Costs differ across centers in relation to the characteristics of patients and the extent of

    Acute cholecystitis is one of the most frequent abdominal inflammatory processes. If untreated or misdiagnosed it can result in severe complications such as gallbladder rupture, abscesses, or peritonitis. It was retrospectively reviewed a series of 71 consecutive patients with surgical confirmation of acute cholecystitis and then compared the results of the diagnostic techniques that have been used preoperatively. Over 16 months, 71 consecutive patients (42 women and 29 men; age range: 34-84 years, mean: 58) with acute abdominal pain were operated on for acute cholecystitis at Cardarelli Hospital, Naples. On abdominal plain films, it was retrospectively searched the following signs: densities projected over the gallbladder, linear calcifications in gallbladder walls, gallbladder enlargement, focal gas collections within the gallbladder, and air-fluid levels in the gallbladder wall lumen. On US images it has been looked for: gallbladder wall thickening (>3 mm), intraluminal content in the gallbladder, pericholecystic fluid, US Murphy's sign, and gallbladder distension. On CT images, it has been investigated: gallbladder distensions, wall thickening, intraluminal content, pericholecystic fluid, and inflammatory changes in pericholecystic fat. On plain abdominal films it was found densities projected over the gallbladder (16.9%) and linear calcifications in the gallbladder wall (4.6%). US appears to be the most useful imaging technique in patients with suspected acute cholecystitis, for both screening and final diagnosis. CT plays a limited role in the early assessment of these patients, but can a useful tool in diagnosing acute cholecystitis in patients with questionable physical findings or in investigating related complications.

    A cross-sectional study of 1804 consecutive patients. The aim of this study was to investigate the prevalence of pathological pain and its distribution features in patients with chronic lumbar spinal disorders. Clinical spinal disorders can involve pathological neuropathic pain (NeP) as well as physiological nociceptive pain (NocP), as they have varied pathology, including spinal cord injury, stenosis, and compression. A study conducted by the Japanese Society for Spine Surgery and Related Research (JSSR) has determined a prevalence of 29.4% for NeP in patients with lumbar spinal disorder. However, the data did not include information on pain location. Patients aged 20 to 79 years with chronic lower back pain (≥3 months, visual analog scale score ≥30) were recruited from 137 JSSR-related institutions. Patient data included an NeP screening questionnaire score and pain location (lower back, buttock, and legs). The association between the pain pathology and its location was analyzed statistically using the unpaired t test and Chi-square test followed by Fisher test. P < 0.05 was considered significant. Low back pain subjects showed 31.9% of NeP prevalence, and the pain distribution showed [NocP(%)/NeP(%)] low back pain only cases: 44/22, while low back pain with leg pain cases showed a prevalence of 56/78. This indicates that low back pain alone can significantly induce NocP rather than NeP (P < 0.01). Buttock pain was revealed to significantly induce both lower back pain and leg pain with NeP properties (P < 0.01). Leg pain was revealed to be predominantly neuropathic, especially when it included peripheral pain (P < 0.01). Low back pain with no buttock pain induces NocP rather than NeP. Buttock pain is significantly associated with NeP prevalence whether or not leg pain exists. Leg pain can increase the prevalence of NeP, especially when it contains a peripheral element. 3.

    To assess the functional status and long-term outcomes of endovascular management for the treatment of central veno-occlusive disease in patients undergoing hemodialysis. Retrospective chart evaluation of 600 patients with threatened upper extremity dialysis access showed central veno-occlusive disease in 69 patients (11%; 30 women and 39 men; mean age, 63.9 years; age range, 26-92 years). A total of 92 venous segments were involved with disease. Initial endovascular procedures consisted of transvenous angioplasty (n = 88) and stent placement (n = 6); there were 134 repeat interventions (14 stents). The mean follow-up was 14.5 months (range, 1-44 months). Angiographic data were reviewed prospectively by two independent observers for the extent of veno-occlusive disease. Technical failures were defined as residual stenosis of at least 30% or lesions that were unable to be dilated or crossed. Statistical analysis, including interobserver agreement and Kaplan-Meier analysis, was performed. Technical success rates for initial and follow-up interventional procedures were 90% (81 of 92 segments) and 96% (129 of 134 interventions), respectively. Two complications required treatment with interventional procedures. There was excellent interobserver agreement (kappa = 0.84; 95% confidence interval: 0.67, 0.93) for grading the degree of venous stenoses. Primary patency rates of hemodialysis access at 1, 6, and 12 months were 81%, 46%, and 22%, respectively, which significantly (P = .001) improved to assisted patency rates of 91%, 77%, and 63% at 1, 6, and 12 months, respectively. Endovascular management including a combination of angioplasty and selective stent placement can be effectively used to treat central veno-occlusive disease and preserve functional access in patients with threatened upper extremity dialysis access.

    BACKGROUND: Follow-up studies have shown that patients with ulcer disease are at risk of developing reflux esophagitis (RE) after successful eradication of Heliobacter pylori. It is still not clear whether this is induced by eradication of H. pylori or whether RE is already present at the time the ulcer is diagnosed. A cross-sectional study was done in consecutive patients suffering from active ulcer disease in order to assess coincidental RE. METHODS: Patients with an active duodenal or gastric ulcer were included in the study. Concomitant RE and the presence of hiatal hernia (HH) were scored. Biopsy specimens were taken for detection of H. pylori. RESULTS: In 375 patients (77%), an active duodenal ulcer was the only abnormality. In 43 patients (8.8%), duodenal ulcer and concomitant RE were present and 69 patients (14.2%) had a duodenal ulcer with concomitant HH. Patients with a duodenal ulcer were significantly younger than patients with concomitant RE or HH. From 374 patients (76.8%) with a duodenal ulcer, biopsy specimens were available for the detection of H. pylori. The majority of duodenal ulcer patients were H. pylori-positive. H. pylori was significantly more often present in patients with an active duodenal ulcer than it was in duodenal ulcer patients suffering from concomitant RE (P=0.04). In 218 patients (76%), a gastric ulcer was the only abnormality. Fifteen patients (5.2%) also had RE and 54 patients (18.8%) had a concomitant HH. There was no difference in H. pylori status in these three groups of patients. CONCLUSIONS: Given the low prevalence of concomitant RE, it is concluded that this condition is likely to occur in a large percentage of patients suffering from H. pylori-positive ulcer disease after successful eradication therapy.

    Retrospective review of charts of 180 consecutive patients with frontal sinus fractures managed by plastic surgeons at the University of Kentucky between 1987 and 2007 was performed with institutional review board approval. Twenty-six charts did not meet the criteria. The remaining 154 records provided 1-to-20-year follow-up. The study included 34 patients who underwent cranialization and 120 patients who did not. A low-complication rate of 6% after cranialization is ascribed by the authors to meticulous sinus mucosal debridement; thorough obliteration of the frontal sinus outflow tract (with sterile gelatin sponge pledgets and bone chips from the outer cortex of the temporoparietal skull); and avoidance of avascular barriers, such as abdominal fat. As high-resolution computerized tomography with parasaggital views was introduced, an increasing ability to preoperatively define the extent of injury of the medial and lateral sinus floor was observed. The authors conclude selective use of cranialization is indicated.

  17. Laparoscopic left and right adrenalectomy from an anterior approach – is there any difference? Outcomes in 176 consecutive patients

    Lukas Kokorak

    2016-12-01

    Full Text Available Introduction : Traditionally, in open surgery, right adrenalectomy is considered technically more demanding than its left-sided counterpart. This belief is supposed to be attributable mainly to different anatomic characteristics of the adrenal veins. Whether this opinion is also correct for laparoscopic adrenalectomy remains elusive. Aim : To compare the outcomes of left versus right laparoscopic adrenalectomy from an anterior approach. Material and methods: Retrospective statistical analysis of a prospectively compiled database of consecutive patients undergoing laparoscopic adrenalectomy in a single center with focus on potential differences in the left- versus right-sided procedure in terms of demographic parameters, tumor size, operating time, occurrence of serious intraoperative complications, conversion, length of hospital stay and re-operation rate. Results: One hundred seventy-six patients underwent elective laparoscopic adrenalectomy – 80 left-sided (45.45% and 96 right-sided (54.55%. No significant difference was found between the groups in terms of age (54.09 ±11.2 vs. 56.27 ±11.6; p = 0.2, tumor size (3.39 ±1.86 vs. 3.26 ±1.66; p = 0.64, operating time (71.84 ±22.33 vs. 72.06 ±30.99; p = 0.95, occurrence of serious intraoperative complications (7.5% vs. 10.4%; p = 0.5, conversion (1.25% vs. 1.04%; p = 0.9, length of hospital stay (4.52 ±1.30 vs. 4.37 ±1.91; p = 0.55 or reoperation rate (5% vs. 1%; p = 0.11. There was no mortality. Conclusions : No significant difference was found between the left and right laparoscopic adrenalectomy in terms of operating time, occurrence of serious intraoperative complications, conversion rate or postoperative outcome. Therefore, the opinion that the right-sided procedure is more difficult does not seem to be justified for laparoscopic adrenalectomy from the anterior approach.

    We have retrospectively reviewed the results of all common bile duct (CBD)-stone preoperative asymptomatic patients operated on our unit to point out the feasibility and safety of the laparoscopic cholecystectomy approach without the IOC use. From January 2004 and June 2008 we analyzed all the data from hospital records and follow up results of all the patients who underwent LC. The indications for performing preoperative endoscopic retrograde cholangiopancreatography (ERCP) or selective IOC were abnormal liver function tests, history of jaundice, cholangitis or pancreatitis, and ultrasonographic evidence of CBD stone or dilation (≥ 10 mm). These patients were excluded from study. The follow up of the all patients were done by liver function tests and abdominal ultrasonography when needed at the time of the visit. Between January 2006 and June 2010, 750 patients were operated in our clinic. In 34 patients, operations were converted to open cholecystectomy (OC). Of these 750 patients, 98 of them had one or more exclusion criteria and were excluded from the further analyzes. We did not perform any IOC during LC. Regular follow up of at least two years was obtained in 618 (618/657, 94.0%) patients. No operative mortality was encountered among the patients. Postoperative morbidity was detected in 15 of the patients (2.5%). In one patient, CBD injury was detected (0.017%). The mean follow up was 35 (24 - 74) months. Retained stone was detected in three patients (3/577, 0.5%) during the follow up. This approach allows to omit routine IOC and to perform LC safely in selected patients group given the low percentage of both CBD injuries and symptomatic retained stones observed in the late follow up period in our 618 operated patients, we consider our approach a feasible and safe approach to manage patients with gallbladder stones re-confirming the results of other studies.

    In the prehospital setting, advanced airway management is challenging as it is frequently affected by facial trauma, pharyngeal obstruction or limited access to the patient and/or the patient's airway. Therefore, incidence of prehospital difficult airway management is likely to be higher compared to the in-hospital setting and success rates of advanced airway management range between 80 and 99%. 3961 patients treated by an emergency physician in Zurich, Switzerland were included in this retrospective analysis in order to determine the incidence of a difficult airway along with potential circumstantial risk factors like gender, necessity of CPR, NACA score, GCS, use and type of muscle relaxant and use of hypnotic drugs. 692 patients underwent advanced prehospital airway management. Seven patients were excluded due to incomplete or incongruent documentation, resulting in 685 patients included in the statistical analysis. Difficult intubation was recorded in 22 patients, representing an incidence of a difficult airway of 3.2%. Of these 22 patients, 15 patients were intubated successfully, whereas seven patients (1%) had to be ventilated with a bag valve mask during the whole procedure. In this physician-led service one out of five prehospital patients requires airway management. Incidence of advanced prehospital difficult airway management is 3.2% and eventual success rate is 99%, if performed by trained emergency physicians. A total of 1% of all prehospital intubation attempts failed and alternative airway device was necessary. Copyright © 2015 Elsevier Ireland Ltd. All rights reserved.

    Objective To provide the evidence on the selection and related policies of essential medicine for policy-makers through systematic review of the National Essential Medicine List(NEML) around the world. Method We systematically searched the official websites of the health authorities, like the departments of health and pharmaceutical administrations. We selected the published NEML. Two reviewers independently selected literature and extracted data. We analyzed the time of NEML published and updated, NEML committees, selection criteria, medicine category, number of medicines, and medicine information in NEML and standard treatment guidelines (STGs) as well. Results Thirty-six NEMLs from 25 countries were included with 34 in English and 2 in Chinese. From 1982 to 2009, Twenty-five countries developed their NEMLs respectively. They were updated from four months to eight years. The NEML committee members came from central government, ministry of health, pharmaceutical administrations, ministry of public health, ministry of education, essential medicine division, etc. The committees were composed of clinical specialists, health officials, pharmacists (pharmacologists), medicine educators, economist, statisticians, epidemiologist and experts from WHO/ UNICEF, etc. Most of the countries took the WHO's concept of essential medicine and selection criteria as standard. The applications of essential medicine were reviewed by considering the following aspects: safety, effectiveness, economic characteristics, the main disease burden, rational use of drug and supply. The medicines in NEMLs of 25 countries varied from 103 to 2 033, and the median is 447. The Anatomical Therapeutic Chemical (ATC) classification was used to classify the medicines in NEMLs of 12 countries. The drug information was provided, including generic name, dosage,form of medication and administration route as well. The STGs or formularies covered from 73 to 167 common diseases, including the diagnosis

    Abstract Cohort studies of large series of patients with sarcoidosis over a long period of time are scarce. The aim of this study is to report a 40-year clinical experience of a large series of patients at Bellvitge University Hospital, a tertiary university hospital in Barcelona, Spain. Diagnosis of sarcoidosis required histological confirmation except in certain specific situations. All patients underwent a prospective study protocol. Clinical assessment and follow-up of patients were performed by a multidisciplinary team. From 1976 to 2015, 640 patients were diagnosed with sarcoidosis, 438 of them (68.4%) were female (sex ratio F/M 2:1). The mean age at diagnosis was 43.3 ± 13.8 years (range, 14–86 years), and 613 patients (95.8%) were Caucasian. At diagnosis, 584 patients (91.2%) showed intrathoracic involvement at chest radiograph, and most of the patients had normal pulmonary function. Erythema nodosum (39.8%) and specific cutaneous lesions (20.8%) were the most frequent extrapulmonary manifestations, but there was a wide range of organ involvement. A total of 492 patients (76.8%) had positive histology. Follow-up was carried out in 587 patients (91.7%), over a mean of 112.4 ± 98.3 months (range, 6.4–475 months). Corticosteroid treatment was administered in 255 patients (43.4%), and steroid-sparing agents in 49 patients (7.7%). Outcomes were as follows: 111 patients (18.9%) showed active disease at the time of closing this study, 250 (42.6%) presented spontaneous remission, 61 (10.4%) had remission under treatment, and 165 (28.1%) evolved to chronic sarcoidosis; among them, 115 (19.6%) with mild disease and 50 (8.5%) with moderate to severe organ damage. A multivariate analysis showed that at diagnosis, age more than 40 years, the presence of pulmonary involvement on chest radiograph, splenic involvement, and the need of treatment, was associated with chronic sarcoidosis, whereas Löfgren syndrome and mediastinal lymphadenopathy on chest

    Lumbar synovial cysts (LSCs) are an uncommon cause of radiculopathy and back pain. Open surgical treatment is associated with extensive bone resection and muscle trauma. The endoscopic tubular-assisted LSC resection has not been described in detail. Here the authors assessed the effectiveness of this technique for LSC resection. Eleven patients (4 female and 7 male patients) were operated on via an ipsilateral approach for resection of LSC using an endoscopic tubular retractor system. Preoperative magnetic resonance imaging was evaluated for signs of degeneration and instability. At follow-up a standardized questionnaire including the Oswestry Disability Index and functional outcome according to MacNab criteria was conducted. Additionally, a personal examination with particular reference to back and leg pain was performed. The mean follow-up was 10.5 months. Preoperatively, spondylolisthesis grade 1 was noted in 4 patients (36.4%). Ten patients had bilateral facet joint effusion (90.9%). At follow-up 10 patients reported being free of leg pain (90.9%), eight patients reported no back pain (72.7%), ten patients had full motor strength (90.9%), and 9 patients had no sensory deficit (81.8%). Nine patients reported an excellent or a good clinical outcome (81.8%). The mean Oswestry Disability Index was 4.7%. None of the patients developed new mechanical low back pain or required subsequent fusion procedure. The endoscopic tubular-assisted procedure is a safe way to treat LSC. It offers complete resection of LSC and achieves good clinical outcome by preserving muscle and ligamentous and bony structures, which prevents delayed instability. Copyright © 2017 Elsevier Inc.

    Full Text Available Objective. We reviewed a cohort of patients with previously untreated locoregional advanced head and neck squamous cell carcinoma (HNSCC who received a uniform chemoradiotherapy regimen. Methods. Retrospective review was performed of 105 patients with stage III or IV HNSCC treated at Greater Baltimore Medical Center from 2000 to 2007. Radiation included 125 cGy twice daily for a total 70 Gy to the primary site. Chemotherapy consisted of cisplatin (12 mg/m2/h daily for five days and 5-fluorouracil (600 mg/m2/20 h daily for five days, given with weeks one and six of radiation. All but seven patients with N2 or greater disease received planned neck dissection after chemoradiotherapy. Primary outcomes were overall survival (OS, locoregional control (LRC, and disease-free survival (DFS. Results. Median followup of surviving patients was 57.6 months. Five-year OS was 60%, LRC was 68%, and DFS was 56%. Predictors of increased mortality included age ≥55, female gender, hypopharyngeal primary, and T3/T4 stage. Twelve patients developed locoregional recurrences, and 16 patients developed distant metastases. Eighteen second primary malignancies were diagnosed in 17 patients. Conclusions. The CRT regimen resulted in favorable outcomes. However, locoregional and distant recurrences cause significant mortality and highlight the need for more effective therapies to prevent and manage these events.

    Background: Little is known about the prognostic importance of murmur in unselected patients. It is difficult to distinguish between innocent and significant murmurs. N-terminal pro-brain natriuretic peptide (NT-pro-BNP) and BNP have recently been shown to be useful in small series of patients......-pro-BNP, discovery of valvular heart disease by echocardiography yielded no additional prognostic information. Conclusions: Detection of a cardiac murmur during routine medical examination of hospitalized patients is associated with increased risk of death within a year.

    Compression stockings are the major long-term treatment of non-complicated primary varicose veins recommended by international consensus. Nevertheless there are few data concerning the patient compliance to treatment. Hundred and forty-four patients with varicose veins of primary origin were prospectively recruited and questioned about their compression therapy: 29.2% patients are wearing compression stockings, and for 10.4% on a daily basis; 32.6% do not wear their compression mainly because it is not well tolerated; 38.2% do not have compression treatment because it is not recommended or not prescribed by the physician.

    This study describes the peri-procedural and late complications and angiographic follow-up results of 32 patients with 34 complex aneurysms treated with flow diverter Silk stents in a single centre. In this retrospective study, 40 Silk stents (SS) were implanted in 34 complex intracranial aneurysms in 32 patients. In our series, 20 (58.8%) carotid-ophthalmic internal carotid artery (ICA), six (17.6%) cavernous ICA, two (5.9%) supraclinoid ICA, two (5.9%) petrosal ICA (the same patient- bilateral) and four (11.8%) posterior circulation aneurysms were treated. One of the posterior circulation lesions was a fenestrated-type aneurysm. Twenty wide-necked, saccular; eight neck remnant; four fusiform and two blister-like aneurysms were included in our series. SS were successfully implanted in all patients (100%). Misdeployment occurred in 17.6% of patients. In two of these patients adequate stent openness was achieved via Hyperglide balloon dilatation. Coil embolization in addition to SS placement was utilized in four aneurysms. One patient (3%) experienced transient morbidity due to a thromboembolic event and there was one mortality (3%) due to remote intraparenchymal haemorrhage. Complete occlusion of 27/33 (81.8 %) and 29/33 (87.9 %) aneurysms was achieved six and 12 months after the procedure, respectively. In-stent intimal hyperplasia was detected in 6.1 % patients. Flow-diverter Silk stent implantation is an effective method of treating complex aneurysms with acceptable mortality and morbidity rates. Complete occlusion is achieved in most of the complex aneurysms.

    Full Text Available Background: Different surgical approaches have been described in the past to treat a trapped fourth ventricle (TFV but, unfortunately, these techniques showed a high rate of dysfunction and complications. During the last 10 years the development of neuroendoscopy has dramatically changed the outcome of these patients. Materials and Methods: We conducted a retrospective evaluation of the safety, effectiveness, and long-term outcome of endoscopic aqueductoplasty and stent placement, performed in 18 consecutive patients with symptomatic TFV through a trans-fourth ventricle approach between 1994 and 2010. Thirteen patients underwent endoscopic aqueductoplasty and stent placement and 5 patients underwent aqueductoplasty alone using a tailored suboccipital approach through the foramen of Magendie in prone or sitting position. Results: The mean age of the patients at the time of surgery was 15.2 years. All patients but 3 had a supratentorial ventriculoperitoneal shunt. Fifteen patients presented with slit supratentorial ventricles. At a mean followup of 90.8 months all patients experienced a stable clinical improvement. Only two complications were observed: A transient diplopia due to dysconjugate eye movements in one patient and a transient trochlear palsy in another one. Conclusions: Our experience and the literature review suggest that endoscopic trans-fourth ventricle aqueductoplasty and stent placement is a minimally invasive, safe, and effective technique for the treatment of TFV and should be strongly recommended, especially in patients with supratentorial slit ventricles.

    To characterize peripheral neuropathy subtypes, ancillary studies, and immunologic profiles associated with peripheral neuropathies in patients with systemic lupus erythematosus (SLE). In this 25-year study of 2,097 SLE patients, we characterized peripheral neuropathies due to SLE and compared clinical and SLE-related features in patients with versus those without neuropathy. The prevalence of peripheral neuropathies was 5.9% (123 of 2,097 patients), and 66.7% of these patients (82 of 123) had peripheral neuropathies attributable to SLE. We noted that 17.1% of the patients with peripheral neuropathies due to SLE (14 of 82 patients) had small-fiber neuropathy, which is a painful neuropathy not included in the American College of Rheumatology (ACR) neuropsychiatric SLE (NPSLE) case definitions. SLE patients with small-fiber neuropathies could present with unorthodox neuropathic pain patterns not consistent with a stocking-glove distribution and had associated skin biopsy results suggestive of dorsal root ganglion neuronal cell loss. Compared to SLE patients without peripheral neuropathies, those with peripheral neuropathies had lower mean disease activity (P = 0.01) and higher disease damage (P neuropathies, is warranted.

    Although laparoscopic adjustable gastric banding (LAGB) has been found to be a generally successful weight loss operation, many patients require revision for weight regain, mechanical complications or intolerance to restriction. We report our experience with laparoscopic mini-gastric bypass (LMGB) as a revisional procedure for failed primary LAGB. From June 2007 to November 2012, 48 patients, who had undergone LAGB, underwent revisional surgery to LMGB. Patient demographics, reasons for band removal, interval between removal and LMGB, operative times, complications, change in comorbidities, and weight loss were collected. The revisions to a mini-gastric bypass (MGB) were completed laparoscopically in all cases except in four, when the MGB was deferred because of gastric tube damage. Mean age was 38 years (range 20-59) and BMI was 43.4 ± 4.2 kg/m(2); 82 % of patients were females. Revision was performed after a mean of 28.6 months. The mean hospital stay was 3.25 days. Within 60 days of the MGB, mortality and morbidity were nil. We observed a significant difference in mean BMI after 6 months' follow-up (P < 0.001). Diabetes remission was observed in 88 % of patients, apnea remission in 66 %, and hypertension remission in 66 % after LMGB (p < 0.001). Moreover, four patients with GERD were cured. All LAGB patients had positive outcomes after the conversion to MGB, with a mean gain of 1.7 points in the bariatric analysis and reporting outcome system questionnaire. Our results suggested that LMGB is a safe, feasible, effective and easy-to-perform revisional procedure for failed LAGB.

    This article presents a new method of cranioplasty in which polypropylene polyester knitwear was used as the filling material. The basis for prosthesis shaping was a three-dimensional model of the defect made according to the patient's CT scans. Previously, such material has never been a subject of computer-aided design and computer-aided manufacturing (CAD/CAM) individual forming. The process of the prosthesis design included CT bone scans and mold preparation for each patient. Such prostheses were implanted in 48 patients with cranial defects. The total number of prostheses applied was 51. The follow-up time was at least 6 months up to 36 months. The group of treated patients is described here, and sample pictures are shown to illustrate the results. The smallest defect had a size of 15 cm(2); the biggest, 178 cm(2). The coverage and the aesthetic results were very good in all cases. Two patients had postoperative complications. The cranioplastic solution described here is a valuable addition to the existing reconstructive methods, because of the low cost of the implant, the ease of its adjustment to the shape of the defect, and the short time of preparation.

    2014-01-01

    Full Text Available Background: Although some patients with symptomatic spinal disease may benefit greatly from surgery, their multiple attendant comorbidities may make general anesthesia risky or contraindicated. However, there is scarce literature describing the efficacy and safety of local anesthesia to perform these operations. Here we report seven patients who successfully underwent spinal surgery utilizing local anesthesia to limit the risks and complications of general anesthesia. Methods: Seven patients for whom general anesthesia was contraindicated were prospectively followed for a minimum of 3 months following spinal surgery performed under local anesthesia. Pain and functional improvement were assessed utilizing the Visual Analog Scores (VAS and Oswestry Disability Index (ODI scores. Results: Five patients had interlaminar decompressions for stenosis alone, while two patients had laminectomies for debulking of tumors. The mean duration of surgery was 79.8 ± 16.6 min, the mean estimated blood loss was 157.1 ± 53.4 ml, the mean dose of local anesthetic was 1.9 ± 0.7 mg/kg, and the mean length of hospital stay after surgery was 3.2 ± 1.2 days. There were no intraoperative complications. The surgery resulted in improved VAS and ODI scores consistent with significant improvement in pain (P = 0.017 and functionality (P = 0.011. Conclusions: Performing spinal surgery under local anesthesia is a safe and effective alternative when patient′s major comorbidities preclude a general anesthetic. For all the seven patients studied, spinal surgery, performed under a local anesthetic, resulted in a statistically significant reduction in pain and improvement in function.

    Postoperative cerebrospinal fluid (CSF) leak in neurosurgery remains a significant source of morbidity. TissuePatchDural (TPD), a novel impermeable adhesive membrane, can be used to reinforce dural closure in cases considered at high risk to develop postoperative CSF leak. A retrospective, single-center, clinical investigation was conducted on 119 patients who underwent elective neurosurgical procedures between January and June 2010. Inclusion criteria included adult patients undergoing clean elective surgeries where a primary watertight closure was not possible. Three groups of patients were considered: 1) infratentorial, 67 cases; 2) supratentorial, 34 cases; and 3) spinal, 18 cases. All these patients received TPD to reinforce dural closure. Preoperative (long-term corticosteroid therapy, previous surgery and radiotherapy), intraoperative (site of procedures and size of dural gap), and postoperative (early and late hydrocephalus) conditions were analyzed as possible risk factors associated with CSF leakage. The mean follow-up was 7.14 months (range 6-12 months). CSF leak was detected in 11 of 119 cases (9.2%). The presence of pre- and postoperative risk factors was associated with a higher percentage of CSF leakage: 8 of 22 cases (36.3%) vs. 3 of 97 cases (3.1%) (P < 0.0001). All leaks could be conservatively treated and no patient required readmission or second surgery. No TPD-related adverse or allergic effects were observed. TPD seems to be a safe tool to be used to reinforce dural closure in patients with a high risk of developing CSF leaks. Copyright © 2013 Elsevier Inc. All rights reserved.

    Aim of our study was to evaluate the predictive factors of positive surgical margins (PSM) in a cohort of patients who underwent partial nephrectomy (PN) for renal cell carcinoma. We retrospectively evaluated our Institutional database of patients treated with open or laparoscopic PN between 200 and 2013. Categorical variables were compared using Pearson's chi-square test and linear-by-linear association. Multivariable Cox analysis was used in order to evaluate independent predictors of PSM. Surgical margins were found to be negative in 274 out of 298 patients (91.9%), and the remaining 24 (8.1%) patients had PSM at the final pathological exam. The median clinical size was significantly lower in patients with PSM than those with negative margins (2.6 vs. 3 cm, p=0.03). At univariable analysis, a shorter operative time (p=0.04), a malignant histotype (p=0.04) and higher Fuhrman grade (p=0.02) were observed in patients with positive surgical margins compared to those without PSM. At multivariable analysis, median tumor dimension (p=0.02), the malignant histotype (p=0.01) and the high Fuhrman grade (3-4) (p=0.01) were found to be independent predictive factors of PSM. The most important goal of any PN is to reach negative surgical margins. In our study, clinical tumor dimensions, malignant tumor histotype and the high Fuhrman grade demonstrated to be independent predictive factors of PSM after nephron sparing surgery for renal cell carcinoma. Other prospective, multi-institutional studies are needed in order to confirm these results.

    Purpose: To present the results of stereotactic body radiotherapy (SBRT) for medically inoperable patients with Stage I non-small-cell lung cancer (NSCLC) and contrast outcomes in patients with and without a pathologic diagnosis. Methods and Materials: Between December 2004 and October 2008, 108 patients (114 tumors) underwent treatment according to the prospective research ethics board-approved SBRT protocols at our cancer center. Of the 108 patients, 88 (81.5%) had undergone pretreatment whole-body [18F]-fluorodeoxyglucose positron emission tomography/computed tomography. A pathologic diagnosis was unavailable for 33 (28.9%) of the 114 lesions. The SBRT schedules included 48 Gy in 4 fractions or 54-60 Gy in 3 fractions for peripheral lesions and 50-60 Gy in 8-10 fractions for central lesions. Toxicity and radiologic response were assessed at the 3-6-month follow-up visits using conventional criteria. Results: The mean tumor diameter was 2.4-cm (range, 0.9-5.7). The median follow-up was 19.1 months (range, 1-55.7). The estimated local control rate at 1 and 4 years was 92% (95% confidence interval [CI], 86-97%) and 89% (95% CI, 81-96%). The cause-specific survival rate at 1 and 4 years was 92% (95% CI, 87-98%) and 77% (95% CI, 64-89%), respectively. No statistically significant difference was found in the local, regional, and distant control between patients with and without pathologically confirmed NSCLC. The most common acute toxicity was Grade 1 or 2 fatigue (53 of 108 patients). No toxicities of Grade 4 or greater were identified. Conclusions: Lung SBRT for early-stage NSCLC resulted in excellent local control and cause-specific survival with minimal toxicity. The disease-specific outcomes were comparable for patients with and without a pathologic diagnosis. SBRT can be considered an option for selected patients with proven or presumed early-stage NSCLC.

    Full Text Available Abstract Objective To compare outcomes between children ( Summary of background data Reported complication rates for children undergoing surgery for Graves’ disease are worse than for adults. Methods 100 consecutive patients (32 children; 68 adults who underwent total thyroidectomy for Graves’ disease (GD by a high-volume endocrine surgery team from were compared. Results The mean patient age was 9.7 yrs (range 3.4-17.9 yrs in children versus 44.9 yrs (range 18.4-84.2 yrs in adults. Operative times were longer in children (2.18 ± 0.08 hrs than in adults (1.66 ± 0.03 hrs (p = 0.003. Pediatric thyroid specimens averaged 38.6.0 ± 8.9 gm (range: 9–293 gm and adult thyroid specimens averaged 48.0 ± 6.4 gm (range: 6.6-203 gm (p = 0.34. Thyroid to body weight ratios were greater in children (0.94 ± 0.11 gm/kg than adults (0.67 ± 0.8 gm/kg (p = 0.05. In all patients, the hyperthyroid state resolved after surgery. There was no operative mortality, recurrence, or permanent hypoparathyroidism. Transient post-operative hypocalcemia requiring calcium infusion was greater in children than adults (6/32 vs. 1/68; p = 0.004. Transient recurrent laryngeal nerve dysfunction occurred in two children and in no adults (p = 0.32. Postoperative hematoma occurred in two adults and in no children (p = 0.46. The length of stay was longer for children (1.41 ± 0.12 days than for adults (1.03 ±0.03 days (p = 0.004. Conclusion Surgical management of GD is technically more challenging in children as evidenced by longer operative times. Whereas temporary hypocalcemia occurs more commonly in children than adults, the risks of major complications including disease recurrence, permanent hypoparathyroidism, recurrent laryngeal nerve injury, or neck hematoma were indistinguishable. These data suggest that excellent and equivalent outcomes can be achieved for GD surgery in children and adults when care is rendered

    AIM: To assess the lifetime cumulative incidence of porGl venous thrombosis (PVT) in the general population.METHODS: Between 1970 and 1982, 23 796 autopsies,representing 84% of all in-hospital deaths in the Malmo city population, were performed, using a standardised protocol including examination of the portal vein. PVT patients were characterised and the PVT prevalence at autopsy, an expression of life-time cumulative incidence,assessed in high-risk disease categories and expressed in terms of odds ratios and 95% CI.RESULTS: The population prevalence of PVT was 1.0%.Of the 254 patients with PVT 28% had cirrhosis, 23%primary and 44% secondary hepatobiliary malignancy,10% major abdominal infectious or inflammatory disease and 3% had a myeloproliferative disorder. Patients with both cirrhosis and hepatic carcinoma had the highest PVT risk, OR 17.1 (95% CI 11.1-26.4). In 14% no cause was found; only a minority of them had developed portal-hypertension-related complications.CONCLUSION: In this population-based study, PVT was found to be more common than indicated by previous clinical series. The markedly excess risk in cirrhosis and hepatic carcinoma should warrant an increased awareness in these patients for whom prospective studies of directed intervention might be considered.

    Full Text Available Breast reconstruction using free tissue transfer is an increasingly utilised oncoplastic procedure. The aim was to review all bilateral breast reconstructions using abdominal free flaps by a single surgeon over an 11-year period (2003–2014. A retrospective review was performed on all patients who underwent bilateral breast reconstruction using abdominal free flaps between 2003 and 2014 by the senior author (DAM. Data analysed included patient demographics, indication for reconstruction, surgical details, and complications. Fifty-five female patients (mean 48.6 years [24–71 years] had bilateral breast reconstruction. The majority (41, 74.5% underwent immediate reconstruction and DIEP flaps were utilised on 41 (74.5% occasions. Major surgical complications occurred in 6 (10.9% patients, all of which were postoperative vascular compromise of the flap. Failure to salvage the reconstruction occurred on 3 (5.5% occasions resulting in a total flap failure rate of 2.7%. Obesity (>30 kg/m2 and age > 60 years were shown to have a statistically increased risk of developing postoperative complications (P60 years were associated with higher complication rates.

    Full Text Available Context: Type 2 diabetes mellitus doubles the odds of suffering from depressive illness. Co-morbid depression is associated with poorer outcomes in diabetes mellitus in terms of glycemic control, medication adherence, quality of life, physical activity, and blood pressure control. Aim: The present study aims to estimate the prevalence of depression among a consecutive group of patients with type 2 diabetes and assess its impact on glycemic and blood pressure control. Setting: Outpatient department of the endocrinology department of a university affiliated teaching hospital in north India. Subjects: Consecutive adult patients (18-65 years with type 2 diabetes mellitus of over 5-year duration with no prior history of psychiatric illnesses or intake of anti-depressants. Materials and Methods: A semi-structured questionnaire was used for demographic data, HbA1c was obtained to assess glycemic control, and blood pressure was recorded twice during patient interview to assess blood pressure control. Depression was assessed with the Major Depression Inventory and scores obtained were classified as consistent with mild, moderate and severe depression. Data was analyzed with SPSS v16, and multiple logistical regression test was done to compare the effect of depression on glycemic control after adjusting for age and sex. Results: Of the 80 patients interviewed, 31 (38.8% had depressive symptoms. Among them 20 (25% had mild depression, 10 (12.5% had moderate depression, and 1 (1.3% had severe depression. Conclusions: Over one third of patients with type 2 diabetes mellitus of over 5-year duration had depressive symptoms. The presence of depressive symptoms was associated with a significant worsening of glycemic control.

  7. Magnetoencephalographic study of hand and foot sensorimotor organization in 325 consecutive patients evaluated for tumor or epilepsy surgery

    Conclusions: MEG localization of sensorimotor cortex activation was more successful for the hand compared to the foot. In patients with neural lesions, there were signs of brain reorganization as measured by more frequent ipsilateral motor cortical activation of the foot in addition to the traditional sensory and motor activation patterns in the contralateral hemisphere. The presence of ipsilateral neural reorganization, especially around the foot motor area, suggests that careful mapping of the hand and foot in both contralateral and ipsilateral hemispheres prior to surgery might minimize postoperative deficits.

    Correlations between neurological symptoms and brain MRI changes during the course of SSPE in 10 patients were studied. Visual agnosia and mental regression - very frequent symptoms at the early stages of the disease were caused by nearly symmetrical, focal involvement of the occipital and frontal white matter in all cases. Pyramidal and extrapyramidal disturbances reflected rather diffuse lesions of both cerebral hemispheres in late second stage of the illness. In cases with clinical improvement the brain changes disclosed an entire stability, but not diminishing intensity. (author) 9 refs, 8 figs, 3 tabs

    ObjectiveThis study was designed to evaluate the clinical application of preoperative auxiliary embolization for juvenile nasopharyngeal angiofibroma (JNA) by direct puncture embolization (DPE) of the tumor in combination with transarterial embolization (TAE). The study included 22 patients. An 18-gauge needle was used to puncture directly into the tumor, and 20-25 % N-butyl cyanoacrylate was injected under the guidance of fluoroscopy after confirming the placement of the needle into the JNA and no leaking into the surrounding tissue. Tumors were obstructed later via TAE. The supplying arteries of JNA were from branches of the internal carotid and external carotid arteries. Control angiography showed the obliteration of contrast stain in the entire tumor mass and the distal supplying arteries disappeared after DPE in combination with TAE. Surgical resection was performed within 4 days after embolization and none of the patients required blood transfusion. The use of DPE in combination with TAE was a safe, feasible, and efficacious method. It can devascularize effectively the JNAs and reduce intraoperative bleeding when JNAs are extirpated.

    The purposes of this study were to describe a technique for treatment of meralgia paresthetica (lateral femoral cutaneous neuropathy) using ultrasound guidance and to report the results of treatment. Twenty consecutive patients (7 male and 13 female; age range, 23-66 years; mean, 39 years) with meralgia paresthetica confirmed by electromyography were treated with perineural injection of 1 mL of methylprednisolone acetate (40 mg/mL) and 8 mL of mepivacaine, 2%, under direct ultrasound guidance. Main outcome measures included the technical success of the procedure, visual analog scale score for the lateral femoral cutaneous nerve (pain, burning sensation, and paresthesia), and visual analog scale global quality of life score. Technical success (successful nerve block at the distribution of the lateral femoral cutaneous nerve) was achieved in all patients. Five patients felt slight sharp pain during needle insertion. The symptoms in 16 patients (80%) diminished progressively after the first week. The 4 remaining patients (20%) required a further perineural injection. The symptoms disappeared in all patients 2 months after injection (mean visual analog scale score ± SD for lateral femoral cutaneous neuropathy at baseline, 8.1 ± 2.1; at 2 months, 2.1 ± 0.5; t = 6.2; P meralgia paresthetica with ultrasound-guided perineural injections resulted in substantial symptom relief in most patients 2 months after injection. Randomized placebo-controlled trials of this treatment should be considered in the future.

    Although extremity chronic osteomyelitis is common in China, updated data were still limited regarding its characterizations. The present study aimed to review clinical features of extremity chronic osteomyelitis in Southern China.A retrospective analysis was conducted in the patients who had sought medical attention from January 2010 to April 2015 for extremity chronic osteomyelitis in Nanfang Hospital in Southern China. Clinical data were collected and analyzed.A total of 394 patients (307 males and 87 females) were included, giving a gender ratio of 3.53. The median age at first diagnosis was 42 years for all. The most frequent type was traumatic osteomyelitis (262 cases, 66.50%), which was mainly caused by open injury (166 cases, 63.36%) and during a road accident (91 cases, 34.73%). Single-site infection accounted for 81.98% (323 cases), with tibia (126 cases), femur (79 cases), calcaneus (37 cases), and toes (37 cases) as the top sites. The positive rate of intraoperative culture was 70.63% (214/303), 78.97% (169/214) of which was monomicrobial infection. Staphylococcus aureus (59 cases) was the most frequent bacteria for monomicrobial infection, followed by Pseudomonas aeruginosa (29 cases) and Escherichia coli (11 cases). The positive ratios of preoperative serum white blood cell (WBC), erythrocyte sedimentation rate (ESR), C-reactive protein (CRP), procalcitonin (PCT), interleukin-6 (IL-6), and tumor necrosis factor alpha (TNF-α) were 21.63%, 64.92%, 53.27%, 42.25%, 72.82%, and 66.67%, respectively. The most frequently used intravenous antibiotic was cephalosporins. The overall cure rate was 77.74%, with a total amputation rate of 16.75%.In this representative Chinese cohort, extremity chronic osteomyelitis was mostly caused by open injury and during a road accident, predominated in males and favored the tibia. S. aureus was the most frequent pathogenic organism. Preoperative elevated levels of serum IL-6, TNF-α, and ESR may be helpful diagnostic

    Ovarian pathology, although rare in children, must be included in the differential diagnosis of all girls who present with abdominal pain, an abdominal mass, or precocious puberty. To improve clinical appreciation of these lesions, the authors reviewed the presentation, evaluation, and outcome of all patients with ovarian pathology surgically treated at their institution since 1985. One hundred two girls (aged 9.8 +/- 5.5 years; range, 2 days to 20 years) underwent 106 separate ovarian operations (43 salpingo-oophorectomies, 21 oophorectomies, 33 ovarian cystectomies, and 9 ovarian biopsies). Of those presenting with acute abdominal pain (n = 59), 25 (42%) had ovarian torsion (14 associated with a mature teratoma), and only 1 (2%) had a malignant tumor. In contrast, of those presenting with an abdominal mass (n = 23), 6 (26%) had malignancies. There was no age difference between those with benign disease (9.9 +/- 5.6 years; n = 96) and those with malignant tumors (8.6 +/- 3.9 years, n = 10). Nine children had 10 operations for presumed malignant tumors (3 dysgerminomas, 2 immature teratomas with foci of yolk sac tumor, 2 juvenile granulosa cell tumors, 1 yolk sac tumor, and 1 Sertoli-Leydig cell tumor). These patients all had unilateral salpingo-oophorectomy, 4 had chemotherapy, and all are now disease free at 8.4 +/- 4.1 years follow-up. Ovarian pathology remains a rare indication for surgery in girls less than 20 years of age. Because most of these lesions are benign, ovarian-preserving operations should be performed whenever feasible. Copyright 2001 by W.B. Saunders Company.

    The Absorb™ BVS is a bioresorbable, everolimus-eluting scaffold approved and marketed for coronary use. Published data on long-term results after treatment are limited to a small number of patients, most of them with elective PCI of simple lesions. The importance of scaffold resorption is variably appreciated among cardiologists, and indications for use from health technology assessment bodies or guidelines are missing. Instruments are needed to collect, share and assess the experience being accumulated with this new device in several centres. The BVS-RAI Registry is a spontaneous initiative of a group of Italian interventional cardiologists in cooperation with Centro di Ricerche Farmacologiche e Biomediche "Mario Negri" Institute, and is not recipient of funding or benefits originating from the BVS manufacturer. It is a prospective registry with 5-year follow-up of all consecutive patients who have undergone successful implantation of 1 or more coronary BVS following the indications, techniques and protocols used in each of the participating institutions. Outcome measures are BVS target lesion failure within one year and device-oriented major adverse cardiac events within 5years. The registry started in October 2012 and will extend enrolment throughout 2015, with the aim to include about 1000 patients. ClinicalTrials.gov identifier is CT02298413. The BVS-RAI Registry will contribute observational knowledge on the long-term safety and efficacy of the Absorb™ BVS as used in a number of Italian interventional centres in a broad spectrum of settings. Unrewarded and undirected consecutive patient enrolments are key-features of this observation, which is therefore likely to reflect common clinical practice in those centres.

    A case report. To report the successful consecutive spinal osteotomies of multiple segments performed on a patient with extremely severe kyphotic deformity. There have been no reports on the experience and surgical strategy of spinal osteotomy on multiple segments for severe global spine deformity. A 48-year-old man, a patient with ankylosing spondylitis with "chin-on-pubis" deformity, underwent consecutive spinal osteotomies to correct the severe, fixed global kyphosis. The axial skeletons from the skull, all vertebrae, and both sacroiliac joints and hip joint were fused into a single bone. After both hip resectional arthroplasties for the first step, staged, sequential spinal osteotomies, including pedicle subtraction osteotomy (PSO) on C6, posterior vertebral column resection on T11-T12, and PSO on L3, were performed. Finally, both total hip arthoroplasties were performed. The chin-brow vertical angle improved from 140° to 15°. Correction angles of 45°, 70°, and 30° in the cervical, thoracic, and lumbar spines, respectively, were achieved without complication. At the last follow-up, excellent improvement in activities of daily living and horizontal gaze were achieved. This is the first report on C6 PSO and spinal osteotomies in whole spine segments. For patients with a severe global kyphotic deformity, it is important to place the patient in a stable prone position so that corrective surgery can be performed on the thoracolumbar spine. To accomplish this, initially correcting the deformities in the hip joints and the cervical spine can yield excellent clinical results.

    After severe reactor emergencies with release of radioactive iodine, elevated thyroid cancer risk in children and adolescents is considered the main health consequence for the population exposed. We studied thyroid cancer outcome after 11.3 years' median follow-up in a selected, very high-risk cohort, 234 Chernobyl-exposed Belarusian children and adolescents undergoing postsurgical radioiodine therapy (RIT) in Germany. Cumulatively 100 children with or (without; n = 134) distant metastasis received a median 4 (2) RITs and 16.9 (6.6) GBq, corresponding to 368 (141) MBq/kg iodine-131. Outcomes were response to therapy and disease status, mortality, and treatment toxicity. Of 229 patients evaluable for outcome, 147 (64.2%) attained complete remission [negative iodine-131 whole-body scan and TSH-stimulated serum thyroglobulin (Tg) 10 μg/L, decrease from baseline in radioiodine uptake intensity in ≥ 1 focus, in tumor volume or in Tg). Except for 2 recurrences (0.9%) after partial remission, no recurrences, progression, or disease-specific mortality were noted. One patient died of lung fibrosis 17.5 years after therapy, 2 of apparently thyroid cancer-unrelated causes. The only RIT side effect observed was pulmonary fibrosis in 5 of 69 patients (7.2%) with disseminated lung metastases undergoing intensive pulmonary surveillance. Experience of a large, very high-risk pediatric cohort with radiation-induced differentiated thyroid carcinoma suggests that even when such disease is advanced and initially suboptimally treated, response to subsequent RIT and final outcomes are mostly favorable.

    To evaluate the efficacy of portal vein embolization (PVE) with n-Butyl-cyanoacrylate (NBCA) through an ipsilateral approach before major hepatectomy. Secondary end-points were PVE safety, liver resection and patient outcome. Over a 5-year period 50 non-cirrhotic consecutive patients were included with primary or secondary liver cancer treatable by hepatectomy with a liver remnant (FLR) volume less than 25% or less than 40% in diseased livers. There were 37 men and 13 women with a mean age of 57 years. Colorectal liver metastases were the most frequent tumor and patients were previously exposed to chemotherapy. FLR increased from 422 ml to 629 ml (P < 0.001) after PVE, corresponding to anincrease of 52%. The FLR ratio increased from 29.6% to 42.3% (P < 0.001). Kinetic growth rate was 2.98%/week. A negative association was observed between increase in the FLR and FLR ratio and FLR volume before PVE (P = 0.002). In 31 patients hepatectomy was accomplished and only one patient presented with liver insufficiency within 30 days after surgery. PVE with NBCA through an ipsilateral puncture is effective before major hepatectomy. Meticulous attention is needed especially near the end of the embolization procedure to avoid complications.

    We analysed the prevalence of the most common hereditary thrombophilia (hTP) - factor V Leiden (FVL) mutation, prothrombin 20210 G>A substitution (PT) - and the 677 C>T replacement in the 5,10-methylenetetrahydrofolate reductase (MTHFR) gene in Caucasian patients with a history of two and more consecutive recurrent miscarriages (RMs) as compared to healthy controls with an identical ethnic background and at least one live birth. A multicenter analysis of three hTP was performed in 641 RM patients identically screened at specialized university centres. The study groups consisted of 240 patients with 2 (1) and 401 patients with >2 miscarriages (2) and were compared with 157 controls. There was no significant difference in the prevalence of the hTP between RM patients and controls nor within the two study groups. Subgroup analysis showed that the homozygous MTHFR polymorphism was significantly more prevalent in the study group 2 as compared to study group 1 (13.9 versus 7.9%, P = 0.02). In Caucasians, maternal FVL or PT mutations do not seem to contribute to the pathophysiology of RM, irrespective of the number of miscarriages. However, the role of the homozygous MTHFR polymorphism merits further investigation. © 2013 John Wiley & Sons Ltd.

    Fifty-six consecutive patients in a referral-based practice seeking treatment for a complex chronic painful temporomandibular disorder (TMD) were enrolled in a retrospective study to evaluate the skeletal relationship of patients with TMD compared to the distribution of skeletal patterns found in the average population. During the standard clinical workup, lateral cephalometric radiographs were performed. Using Wits appraisal all of the fifty-six (56) cephalometric radiographs were analyzed. Based on the results of the Wits analysis, 34.6 percent of the patients were skeletal Class I, 63.6 percent were skeletal Class II, and 1.8 percent were skeletal Class III. These results were compared with the data published by the National Health and Nutrition Examination Survey (NHANES) in Proffit's text Contemporary Orthodontics. This study states that in the general population occlusal diversity is eighty to eighty-five percent (80-85%) skeletal Class I, fifteen percent (15%) are skeletal Class II, and one percent (1%) are skeletal Class III. The conclusion can be drawn that the patient sampling analyzed shows that TMD patients have a higher prevalence for skeletal Class II than the general population.

    Purpose: To determine if use of an electromagnetic navigation system (EMN) decreases radiation dose and procedure time of CT fluoroscopy guided lung biopsy in lesions smaller than 2.5 cm. Materials/methods: 86 consecutive patients with small lung masses (<2.5 cm) were approached. 60 consented and were randomized to undergo biopsy with CT fluoroscopy (CTF) (34 patients) or EMN (26 patients). Technical failure required conversion to CTF in 8/26 EMN patients; 18 patients completed biopsy with EMN. Numerous biopsy parameters were compared as described below. Results: Average fluoroscopy time using CTF was 28.2 s compared to 35.0 s for EMN (p = 0.1). Average radiation dose was 117 mGy using CTF and 123 mGy for EMN (p = 0.7). Average number of needle repositions was 3.7 for CTF and 4.4 for EMN (p = 0.4). Average procedure time was 15 min for CTF and 20 min for EMN (p = 0.01). There were 7 pneumothoracesin the CTF group and 6 pneumothoraces in the EMN group (p = 0.7). One pneumothorax in the CTF group and 3 pneumothoraces in the EMN group required chest tube placement (p = 0.1). One pneumothorax patient in each group required hospital admission. Diagnostic specimens were obtained in 31/34 patients in the CTF group and 22/26 patients in the EMN group (p = 0.4). Conclusions: EMN was not statistically different than CTF for fluoroscopy time, radiation dose, number of needle repositions, incidence of pneumothorax, need for chest tube, or diagnostic yield. Procedure time was increased with EMN.

    PURPOSE: The most common complication following treatment of a clavicle fracture is nonunion. Most nonunions are symptomatic and treatment is mostly operative. The aim of this study was to describe risk profiles of patients developing nonunion and what outcome is observed following operative...... treatment of clavicle nonunions. METHODS: In a consecutive series of 729 clavicle fractures we retrospectively identified 55 that developed nonunion (49 diaphysial and six lateral). All were treated operatively by reconstruction with (n = 28) or without (n = 27) autologous bone graft. Assessment...... was anatomic site, fracture complexity, female gender, smoking habits and initial treatment. A total of eight post-operative complications were found. Remission of symptoms was reported by 29 of the 33. Outright satisfaction with current shoulder condition was reported by 24. The overall median DASH was 8...

    The precise incidence rates of multiple primary colorectal cancers in esophageal cancer patients are unknown. In total, 480 consecutive patients with esophageal cancers surgically resected in the Kumamoto University Hospital received preoperative total colonoscopy for the assessment of colorectal disease between April 2005 and February 2016. We retrospectively investigated the occurrence of synchronous colorectal cancer with esophageal cancer. In addition, we examined the risk factors for the incidence of multiple primary colorectal cancers. Of the 480 patients, 14 (2.9 %) had synchronous colorectal cancers, 13 had well-differentiated tubular adenocarcinomas, and 1 had papillary adenocarcinoma. Other 14 patients had metachronous colorectal cancer. The current incidence rates of synchronous and total (both synchronous and metachronous) colorectal cancers outnumbered those in normal healthy population and those in esophageal cancer patients which previously reported by The Japan Esophageal Society. The age ≥70 years (hazard ratio 4.82, 95 % confidence interval 1.473-15.78; p = 0.009) and Brinkman index ≥800 (hazard ratio 3.47, 95 % confidence interval 1.056-11.37; p = 0.040) were the independent risk factors for the incidence of synchronous colorectal cancer. They were also the independent risk factors for the incidence of total colorectal cancer. The results of the present study suggested that pretreatment screening with total colonoscopy is meaningful for patients with esophageal cancer, because the frequency of synchronous colorectal cancer was not negligible. Particularly, in patients >70 years and with history of heavy smoking, pretreatment colonoscopy might be necessary.

    The objective of this study is to examine the costs attributable to robotic-assisted laparoscopic hysterectomy from a broad healthcare sector perspective in a register-based longitudinal study. The population in this study were 7670 consecutive women undergoing hysterectomy between January 2006 and August 2013 in public hospitals in Denmark. The interventions in the study were total and radical hysterectomy performed robotic-assisted laparoscopic hysterectomy (RALH), total laparoscopic hysterectomy (TLH), or open abdominal hysterectomy (OAH). Service use in the healthcare sector was evaluated 1 year before to 1 year after the surgery. Tariffs of the activity-based remuneration system and the diagnosis-related grouping case-mix system were used for valuation of primary and secondary care, respectively. Costs attributable to RALH were estimated using a difference-in-difference analytical approach and adjusted using multivariate linear regression. The main outcome measure was costs attributable to OAH, TLH, and RALH. For benign conditions RALH generated cost savings of € 2460 (95% CI 845; 4075) per patient compared to OAH and non-significant cost savings of € 1045 (95% CI -200; 2291) when compared with TLH. In cancer patients RALH generated cost savings of 3445 (95% CI 415; 6474) per patient when compared to OAH and increased costs of € 3345 (95% CI 2348; 4342) when compared to TLH. In cancer patients undergoing radical hysterectomy, RALH generated non-significant extra costs compared to OAH. Cost consequences were primarily due to differences in the use of inpatient service. There is a cost argument for using robot technology in patients with benign disease. In patients with malignant disease, the cost argument is dependent on comparator.

    Full Text Available PURPOSE: The authors analyzed the 30-day and 6-month outcomes of 1,126 consecutive patients who underwent coronary stent implantation in 1996 and 1997. METHODS: The 30-day results and 6-month angiographic follow-up were analyzed in patients treated with coronary stents in 1996 and 1997. All patients underwent coronary stenting with high-pressure implantation (>12 atm and antiplatelet drug regimen (aspirin plus ticlopidine. RESULTS: During the study period, 1,390 coronary stents were implanted in 1,200 vessels of 1,126 patients; 477 patients were treated in the year 1996 and 649 in 1997. The number of percutaneous procedures performed using stents increased significantly in 1997 compared to 1996 (64 % vs 48%, p=0.0001. The 30-day results were similar in both years; the success and stent thrombosis rates were equal (97% and 0.8%, respectively. The occurrence of new Q wave MI (1.3% vs 1.1%, 1996 vs 1997, p=NS, emergency coronary bypass surgery (1% vs 0.6%, 1996 vs 1997, p=NS and 30-day death rates (0.2% vs 0.5%, 1996 vs 1997, p=NS were similar. The 6-month restenosis rate was 25% in 1996 and 27% in 1997 (p= NS; the target vessel revascularization rate was 15% in 1996 and 16% in 1997 (p = NS. CONCLUSIONS: Intracoronary stenting showed a high success rate and a low incidence of 30-day occurrence of new major coronary events in both periods, despite the greater angiographic complexity of the patients treated with in 1997. These adverse variables did not have a negative influence at the 6-month clinical and angiographic follow-up, with similar rates of restenosis and ischemia-driven target lesion revascularization rates.

    Laparoscopic anti-reflux surgery is conventionally performed using two 10/12 mm ports. While laparoscopic procedures reduce post-operative pain, the use of larger ports invariably increases discomfort and affects cosmesis. We describe a new all 5 mm ports technique for laparoscopic anti-reflux surgery and present a review of our initial experience with this approach. All patients undergoing laparoscopic fundoplication over a 35 month period from February 2013 under the care of a single surgeon were included. A Lind laparoscopic fundoplication was performed using an all 5 mm port technique. Data was recorded prospectively on patient demographics, operating surgeon, surgical time, date of discharge, readmissions, complications, need for re-intervention, and reasons for admission. Two hundred and five consecutive patients underwent laparoscopic fundoplication over the study period. The all 5 mm port technique was used in all cases, with conversion to a 12 mm port only once (0.49%). Median operating time was 52 min 185 (90.2%) patients were discharged as day cases. Increasing ASA grade and the presence of a hiatus hernia were associated with the need for overnight stay with admission required in 33% of patients with ASA 3, compared to 4% with ASA 1 (p = 0.001), and 29% of those with a hiatus hernia vs. 5% without (p effective technique which facilitates same day discharge and minimises port related complications. National commissioning guidelines in the UK should target quality improvements in anti-reflux surgery based around day-case management. This would improve the service for these patients and culminate in cost savings for the NHS. Copyright © 2016. Published by Elsevier Ltd.

    There are limited data on serum total light chain (sTLC) in lymphoma and its relative role on the outcome of diffuse large B cell lymphoma (DLBCL) patients. Blood samples from 46 cases newly diagnosed with DLBCL were collected consecutively during chemotherapy to detect sTLC, IgG, IgA, and IgM levels. Clinical data and survival outcomes were analyzed according to the results of sTLC measurements. In summary, 22 patients (47.8 %) had abnormal k or λ light chain, respectively, and 6 patients (13.0 %) had both abnormal k and λ light chains before chemotherapy. Patients with elevated k light chain more frequently displayed multiple extra-nodal organ involvement (P = 0.01) and had an inferior overall survival (OS) (P = 0.041) and progression-free survival (PFS) (P = 0.044) compared to patients with normal level of k light chain. Furthermore, patients with elevated level of both k and λ also exhibited significant association with shorter OS (P = 0.002) and PFS (P = 0.009). Both elevated k alone and concurrent elevated k and λ had independent adverse effects on PFS (P = 0.031 and P = 0.019, respectively). sTLC level was reduced gradually by treatment in this study and reached the lowest point after the fourth cycle of chemotherapy, which was consistent with the disease behavior during chemotherapy. Considering the small sample size of this study, these results should be confirmed in a larger prospective study.

    The aim of this study was to assess the tolerance and report obtained results with a stable prostacyclin analogue (iloprost) in diabetic patients with severe forms of permanent lower limb ischaemia. Sixty-four consecutive unselected patients, in stage III and IV of Leriche and Fontaine, turned down for vascular surgery after angiography and treated with iloprost during 28 days, were enrolled in this study. Patients were followed-up clinically (ischemic pain, trophic change, walking distance) and with transcutaneous oxymetry (D28). Long-term assessment (6 and 12 months) was expressed as rate of death, major amputation and of live patients with viable limbs and walking. There was no manifestation of intolerance to iloprost. Were considered as responders patients offering a lack or significant decrease in pain, a reduction of trophic lesions and improvement or recovery of walking. Response at two months is lasting: 29 responders (45.3%) and 35 non-responders (54.7%). At 6 months and one year, we observed that 8 (12.5%) and 15 (24.1%) patients respectively had died; 19 (29.6%) and 22 (34.3%) patients underwent major amputation, but 41 (64%) and 34 (53.1%) patients were still alive with their limb and conservative walking. In responder group, at 6 months, 28 (96.5%) patients were alive without amputation for only 13 (37.1%) among non-responders. At one year, 79.3% of the responders and 31.4% of the non-responders were alive without amputation. A total loss of walking, a segmental amputation and a previous amputation of opposite limb were more often noted in no responder group. But no predictive factor was referred to TcPO(2) in particular. Results ware similar in the group of 136 non diabetic patients treated during the same period (67.9% alive with limb at 6 months). This retrospective study, despite its limitations, underlines the clinical particularities of critical ischaemia in diabetics and the good tolerance to iloprost. This point allowed patients, in non

    A quarter century has passed since the first publication of the evolutionary discordance hypothesis, according to which departures from the nutrition and activity patterns of our hunter-gatherer ancestors have contributed greatly and in specifically definable ways to the endemic chronic diseases of modern civilization. Refinements of the model have changed it in some respects, but anthropological evidence continues to indicate that ancestral human diets prevalent during our evolution were characterized by much lower levels of refined carbohydrates and sodium, much higher levels of fiber and protein, and comparable levels of fat (primarily unsaturated fat) and cholesterol. Physical activity levels were also much higher than current levels, resulting in higher energy throughput. We said at the outset that such evidence could only suggest testable hypotheses and that recommendations must ultimately rest on more conventional epidemiological, clinical, and laboratory studies. Such studies have multiplied and have supported many aspects of our model, to the extent that in some respects, official recommendations today have targets closer to those prevalent among hunter-gatherers than did comparable recommendations 25 years ago. Furthermore, doubts have been raised about the necessity for very low levels of protein, fat, and cholesterol intake common in official recommendations. Most impressively, randomized controlled trials have begun to confirm the value of hunter-gatherer diets in some high-risk groups, even as compared with routinely recommended diets. Much more research needs to be done, but the past quarter century has proven the interest and heuristic value, if not yet the ultimate validity, of the model.

    In an effort to promote communication between the formal and phenomenological branches of the high-energy theory community, we provide a description of some important issues in supersymmetric and string phenomenology. We describe each within the context of string constructions, illustrating them with specific examples where applicable. Each topic culminates in a set of questions that we believe are amenable to direct consideration by string theorists, and whose answers we think could help connect string theory and phenomenology.

    The discovery of neutrino mass marks a turning point in elementary particle physics, with important implications for nuclear and astroparticle physics. Here I give a brief update, where I summarize the current status of three-neutrino oscillation parameters from current solar, atmospheric, reactor and accelerator neutrino data, discuss the case for sterile neutrinos and LSND, and also the importance of tritium and double beta decay experiments probing the absolute scale of neutrino mass. In this opininated look at the present of neutrino physics, I keep an eye in the future, and a perspective of the past, taking the oportunity to highlight Joe Schechter's pioneering contribution, which I have had the fortune to share, as his PhD student back in the early eighties.

    Foramen magnum dural arteriovenous fistulas (DAVF) with perimedullary venous drainage represent a small minority of intracranial DAVF, and only a number of small series with limited cases have been reported. The purpose of this retrospective study is to summarize experience of transarterial Onyx embolisation in the treatment of these lesions, with emphasis on the balloon-augmented technique. Five consecutive patients with DAVF at the foramen magnum were treated by transarterial embolisation using the Onyx system. Their symptoms included myelopathy (n=4) and SAH (n=1). Suppliers were from the vertebral artery (VA) (n=4), occipital artery (OA) (n=4), and ascending pharyngeal artery (APA) (n=2), with drainage to the perimedullary veins. After catheterization of the dilated supplier, the fistulous connections, proximal draining veins and appropriate distal segment of the feeders of these DAVF were transarterial embolized using Onyx-18. In three patients, balloon-augmented technique was used to assist embolisation. The technical feasibility of the procedure, angiographic results, and clinical outcome were evaluated. In every case, complete obliteration was achieved. Neither intraprocedural vessel rupture nor other procedure-related complications occurred. The results remained stable in all patients on follow-up angiograms (mean, 7.2 months). At the last clinical follow-up (mean, 17.6 months), two patients showed complete resolution of the initial symptoms, and three patients showed significant improvement. We found that Onyx embolisation is a feasible and safe alternative to open surgery in the treatment of selective DAVF at the foramen magnum. The balloon-augmented technique widens indications for transarterial Onyx packing of these lesions, and improved safety of the procedure. Copyright © 2013. Published by Elsevier Masson SAS.

    Recurrence of anterior shoulder instability after operative repair is an uncommon but disabling condition for which treatment options have been insufficiently studied. Coracoid transfer as described by Latarjet is a highly successful primary operation for recurrent anterior shoulder instability. The purpose of this study was to verify the hypothesis that this procedure is also effective for treating recurrent glenohumeral instability after previous operative repair. Forty-nine consecutive patients with either one (n = 32), two (n = 12), or at least three (n = 5) previous stabilizations other than a Latarjet procedure and recurrence of anterior glenohumeral instability associated with a lesion of the anterior aspect of the glenoid rim had revision with a coracoid transfer as described by Latarjet. Clinical outcomes at a mean of thirty-eight months postoperatively included the subjective shoulder value, the Constant-Murley score, and glenohumeral stability. Standardized anteroposterior and axial radiographs before and after the Latarjet revision were used to grade the degree of glenohumeral osteoarthritis. The results in all forty-nine patients were reviewed. No shoulder redislocated, subluxations recurred in two patients, and five patients reported slight, unspecified shoulder symptoms. No revision surgery was needed. Forty-three shoulders (88%) were subjectively graded as excellent or good; three, fair; and three, poor. Dissatisfaction was associated with persistent pain, and patients with preoperative pain had a twentyfold higher probability of having postoperative pain. The mean subjective shoulder value increased from 53% preoperatively to 79% at the time of follow-up (p Latarjet can effectively restore anterior glenohumeral shoulder stability if previous operation(s) have failed to do so. If recurrence is associated with chronic pain, the pain is likely to persist and compromise the subjective outcome.

    Management of deep facial burns remains one of the greatest challenges in burn care. We have developed a protocol over the past 20 years for management of facial burns that includes excision and coverage with thick autograft. However, the results were not perfect. Deformities of the eyelids, nose and mouth as well as the prominence of skin graft junctures demonstrated the need to explore novel approaches. Integra has been used with success in the management of burns of the trunk and extremities. The purpose of this study was to prospectively evaluate the aesthetic outcome of the use of Integra for deep facial burns. Twelve consecutive patients underwent excision of large, deep facial burns and placement of Integra. Integra provides excellent color and minimally visible skin graft junctures. The texture is good but not as supple as thick autograft. Integra is not well suited for use in the coverage of eyelid burns due to the need to wait 2 weeks for adequate vascularization. In summary, thick autograft remains the gold standard for deep facial burns. However, for patients with extensive burns and limited donor sites, Integra provides an acceptable alternative.

    Full Text Available Introduction This study evaluated the effect of fibrin glue applied as a sandwich film between a two layer pancreatico-jejunostomy anastomosis following pancreaticoduodenectomy. Primary end-points were post-operative pancreatic fistulae, overall complication rates and post-operative length of stay. Methods Pancreaticoduodenectomy was performed by fashioning a two layer pancreatico-jejunostomy with or without a glue sealant which when applied, formed a thin film external to the ductal anastomosis but internal to the seromuscularpancreatic parenchymal layer. Results Following audit of 100 consecutive patients undergoing pancreaticoduodenectomy, patients were separated into two groups; those with glue augmented anastomosis [Glue (G N=50] or those without [No Glue (NG, N=50]. Each group was matched with regard to age [median, G=68 years vs. NG=66 years, (P=0.19] and sex (P=0.84. There were no statistically significant differences between the two groups with respect to overall POPF [G N=7(14% vs. NG N=11(22%, (P=0.42], significant complications (Clavien Grade 3 or more, [G N=4(8% vs. NG N=2(4% (P=0.40], or post-operative length of stay [G 13 days vs. NG 14 days, (P=0.90]. In those patients with the highest fistulae risk score, there were significantly more post-operative pancreatic fistulae in the no glue cohort. There was no mortality in either group. Conclusion This study shows that application of sealant glue significantly reduces post-operative pancreatic fistulae in high-risk patients, but does not reduce overall complications or hospital stay following pancreaticoduodenectomy.

    When we first approached some colleagues allover the world to sound them about a volume dedicated to Professor John Xanthakis on the occasion of completing twenty-five years of scientific activities as fellow of the National Academy of Athens, any possible doubts as to the feasibility of the project were quickly dispelled by their warm and encouraging response. In a short time 50 authors from 15 countries, coming from a wide range of Professor Xanthakis' immediate colleagues, pupils and friends joined to produce the 36 contributions included in this volume. Some of those who where originally approached found themselves un­ able to contribute, because of the time-limit necessarily imposed. Happi­ ly, they were only few in number, and we should like to record our grat­ itude to them for their good wishes for the success of the venture. Their warm words were among the many sources of inspiring encouragement extended to us.

    Cerebral dural arteriovenous fistulas (DAVFs) are rare intracranial vascular lesions but can cause significant morbidity and mortality. To analyze the effect of the center's experience on DAVF embolization efficacy and safety. From May 2008 to October 2014, 57 embolization procedures were attempted on 48 patients (37 men and 11 women; median age: 63.9 years) for DAVF in a single center. DAVF presented with cortical venous reflux in 44/48 cases (91.7%) and hemorrhagic manifestation in 21/48 cases (43.75%). Angiographic occlusion quality, whether complete or incomplete (efficacy), and neurological complications (safety) were recorded. The patient population was divided into four consecutive quartiles during the inclusion period to assess the progress profile. Efficacy and safety outcomes were compared with Fisher's test. A logistic regression was performed to explore a learning curve phenomenon, showing a significant association between the chronological rank in the cohort and embolization efficacy (P=0.007). Significant differences were found between first and last quarter (P=0.036). The endovascular technique involved an arterial injection of Onyx(®) in 36/48 cases (75%), administered via the middle meningeal artery in 25/36 cases (69.5%). The complete occlusion rate improved significantly from 33.3% for the first quartile of the population, to 75.0% for the 2nd and 3rd quartiles and 83.3% for the last quartile. Neurological complications were found in 7/48 patients (14.6%), the rate decreased by 41.7% to 16.7%, without statistically difference. The efficacy and safety of DAVF embolization improved with the experience gained at the center, suggesting the existence of a learning curve. Copyright © 2016 Elsevier Masson SAS.

    Coronary computed tomographic angiography (CCTA) employing CT scanners of 64-detector rows or greater represents a novel noninvasive method for detection of coronary artery disease (CAD), providing excellent diagnostic information when compared to invasive angiography. In addition to its high diagnostic performance, prior studies have shown that CCTA can provide important prognostic information, although these prior studies have been generally limited to small cohorts at single centers. The Coronary CT Angiography EvaluatioN For clinical Outcomes: An InterRnational Multicenter Registry, or CONFIRM, is a large, prospective, multinational, dynamic observational cohort study of patients undergoing CCTA. This registry currently represents more than 32,000 consecutive adults suspected of having CAD who underwent ≥ 64–detector row CCTA at 12 centers in 6 countries between 2005 and 2009. Based on its large sample size and adequate statistical power, the data derived from CONFIRM registry has and will continue to provide key answers to many important topics regarding CCTA. Based on its multisite international national design, the results derived from CONFIRM should be considered as more generalizable than prior smaller single-center studies. This article summarizes the current status of several studies from CONFIRM registry. PMID:22689072

    Dynamic contrast-enhanced (DCE) and dynamic susceptibility contrast (DSC) magnetic resonance imaging (MRI) are the perfusion imaging techniques most frequently used to probe the angiogenic character of brain neoplasms. With these methods, T1- and T2/T2*-weighted imaging sequences are used to image the distribution of gadolinium (Gd)-based contrast agents. However, it is well known that Gd exhibits combined T1, T2, and T2* shortening effects in tissue, and therefore, the results of both DCE- and DSC-MRI can be confounded by these opposing effects. In particular, residual susceptibility effects compete with T1 shortening, which can confound DCE-MRI parameters, whereas dipolar T1 and T2 leakage and residual susceptibility effects can confound DSC-MRI parameters. We introduce here a novel perfusion imaging acquisition and postprocessing method termed Spiral Perfusion Imaging with Consecutive Echoes (SPICE) that can be used to simultaneously acquire DCE- and DSC-MRI data, which requires only a single dose of the Gd contrast agent, does not require the collection of a precontrast T1 map for DCE-MRI processing, and eliminates the confounding contrast agent effects due to contrast extravasation. A detailed mathematical description of SPICE is provided here along with a demonstration of its utility in patients with high-grade glioma. PMID:28090589

    OBJECTIVE Although 3-column osteotomy (3CO) can provide powerful alignment correction in adult spinal deformity (ASD), these procedures are complex and associated with high complication rates. The authors' objective was to assess complications associated with ASD surgery that included 3CO based on a prospectively collected multicenter database. METHODS This study is a retrospective review of a prospectively collected multicenter consecutive case registry. ASD patients treated with 3CO and eligible for 2-year follow-up were identified from a prospectively collected multicenter ASD database. Early (≤ 6 weeks after surgery) and delayed (> 6 weeks after surgery) complications were collected using standardized forms and on-site coordinators. RESULTS Of 106 ASD patients treated with 3CO, 82 (77%; 68 treated with pedicle subtraction osteotomy [PSO] and 14 treated with vertebral column resection [VCR]) had 2-year follow-up (76% women, mean age 60.7 years, previous spine fusion in 80%). The mean number of posterior fusion levels was 12.9, and 17% also had an anterior fusion. A total of 76 early (44 minor, 32 major) and 66 delayed (13 minor, 53 major) complications were reported, with 41 patients (50.0%) and 45 patients (54.9%) affected, respectively. Overall, 64 patients (78.0%) had at least 1 complication, and 50 (61.0%) had at least 1 major complication. The most common complications were rod breakage (31.7%), dural tear (20.7%), radiculopathy (9.8%), motor deficit (9.8%), proximal junctional kyphosis (PJK, 9.8%), pleural effusion (8.5%), and deep wound infection (7.3%). Compared with patients who did not experience early or delayed complications, those who had these complications did not differ significantly with regard to age, sex, body mass index, Charlson Comorbidity Index, American Society of Anesthesiologists score, smoking status, history of previous spine surgery or spine fusion, or whether the 3CO performed was a PSO or VCR (p ≥ 0.06).

    Optimal treatment strategy for retroperitoneal recurrence of testicular cancer involving the inferior vena cava (IVC) is uncertain. The purpose of this study was to validate the hypothesis that surgical resection, en-bloc with the involved segment of IVC and its subsequent reconstruction followed by chemotherapy, would yield better oncologic results than chemotherapy alone. Two consecutive series of patients with retroperitoneal recurrence of testicular cancer involving the IVC, treated with surgical resection plus chemotherapy (group A, n=14) or chemotherapy alone (group B, n=8) were retrospectively reviewed. The mean duration of follow-up was was 65 months (range=8-184). Operative mortality and morbidity in group A, response to chemotherapy in group B, disease-specific survival and quality adjusted life-years (QALY) for both groups, were primary end-points of the study. Postoperative mortality and morbidity (group A) were, respectively, nil and 14%. In group B, two patients (25%) fully responded to chemotherapy and remained free from disease progression. Disease-specific survival at 3 and 5 years was 81% and 54% in group A and 36% in group B both at 3 and 5 years, respectively (p=0.02). QALY was 3.92 in group A and 0.77 for both 3 and 5 years in group B, respectively, (p=0.031). En bloc resection of retroperitoneal recurrence of testicular tumors invading the IVC, followed by chemotherapy, allows a better survival rate compared to chemotherapy alone.

    Full Text Available Abstract Background For recurrent disease or primary therapy of advanced ovarian cancer, cytoreductive surgery (CRS followed by adjuvant chemotherapy is a therapeutic option. The aim of this study was to evaluate the outcome for patients with epithelial ovarian cancer treated with hyperthermic intraoperative chemotherapy (HIPEC and completeness of cytoreduction (CC. Methods Data were retrospectively collected from 111 patients with recurrent or primary ovarian cancer operated with the contribution of visceral surgical oncologists between 1991 and 2006 in a tertiary referral hospital. Results Ninety patients received CRS and 21 patients CRS plus HIPEC with cisplatin. Patients with complete cytoreduction (CC0 were more likely to receive HIPEC. Overall, 19 of 21 patients (90.5 % with HIPEC and 33 of 90 patients (36.7 % with CRS had a complete cytoreduction (P  Conclusions Completeness of cytoreduction was proved to be crucial for long-term outcome. HIPEC procedures in ovarian cancer should be performed in clinical trials to compare CRS, HIPEC and systemic chemotherapy against CRS with systemic chemotherapy. Concerning the safety of HIPEC with cisplatin, the risk of persistent renal failure must be considered when dosage is based on body surface.

    Full Text Available Abstract Background One of the sources of knee pain in osteoarthritis (OA is believed to be related to local chronic inflammation of the knee joints, which involves the production of inflammatory cytokines such as tumor necrosis factor alpha (TNFα, interleukin (IL-6, and nerve growth factor (NGF in the synovial membrane, and these cytokines are believed to promote pathological OA. In the present study, correlations between proinflammatory cytokines in knee synovial fluid and radiographic changes and functional scores and pain scores among OA patients were examined. Methods Synovial fluid was harvested from the knees of 47 consecutive OA patients, and the levels of TNFα, IL-6, and NGF were measured using enzyme-linked immunosorbent assays. Osteoarthritic knees were classified using Kellgren-Lawrence (KL grading (1-4. The Western Ontario and McMaster University Osteoarthritis Index (WOMAC was used to assess self-reported physical function, pain, and stiffness. Results TNFα and IL-6 were detectable in knee synovial, whereas NGF was not. TNFα was not correlated with the KL grade, whereas IL-6 had a significantly negative correlation. We observed differences in the correlations between TNFα and IL-6 with WOMAC scores and their subscales (pain, stiffness, and physical function. TNFα exhibited a significant correlation with the total score and its 3 subscales, whereas IL-6 exhibited a moderately significant negative correlation only with the subscale of stiffness. Conclusions The present study demonstrated that the concentrations of proinflammatory cytokines are correlated with KL grades and WOMAC scores in patients with knee OA. Although TNFα did not have a significant correlation with the radiographic grading, it was significantly associated with the WOMAC score. IL-6 had a significant negative correlation with the KL grading, whereas it had only a weakly significant correlation with the subscore of stiffness. The results suggest that these

    To evaluate the contribution of CT for the management of patients with severe acute exacerbation of colitis (SAC) complicating inflammatory bowel disease (IBD); in particular, its contribution to surgical decision making. All patients who were admitted to our institution for SAC complicating IBD were divided into two groups: group A (those who received surgical treatment); and group B (those who received medical treatment). Admission CT results were compared between groups. From 2006 to 2015, 54 patients [26 male; median age 39 (17-71) years] presenting with SAC were placed in either group A (n = 41; 76%) or group B (n = 13; 24%). Surgical patients in group A more frequently had altered general status (50 vs 17%; P = 0.01). Physical examination, Lichtiger score, endoscopic findings and laboratory results were similar between the groups. There was no significant difference in CT data between the groups with respect to extent of the colitis (pan-colitis in 54 and 69%, respectively, P = 0.35), median colonic thickness [10 (4-16) vs 8 (6-11) mm, P = 0.15], target enhancement (88 vs 77%, P = 0.38) and occurrence of toxic megacolon (2 vs 0%). Admission CT is not helpful in surgical decision making in SAC. Colorectal Disease © 2017 The Association of Coloproctology of Great Britain and Ireland.

  4. The role of dynamic susceptibility contrast-enhanced perfusion MR imaging in differentiating between infectious and neoplastic focal brain lesions: results from a cohort of 100 consecutive patients.

    Full Text Available BACKGROUND AND PURPOSE: Differentiating between infectious and neoplastic focal brain lesions that are detected by conventional structural magnetic resonance imaging (MRI may be a challenge in routine practice. Brain perfusion-weighted MRI (PWI may be employed as a complementary non-invasive tool, providing relevant data on hemodynamic parameters, such as the degree of angiogenesis of lesions. We aimed to employ dynamic susceptibility contrast-enhanced perfusion MR imaging (DSC-MRI to differentiate between infectious and neoplastic brain lesions by investigating brain microcirculation changes. MATERIALS AND METHODS: DSC-MRI perfusion studies of one hundred consecutive patients with non-cortical neoplastic (n = 54 and infectious (n = 46 lesions were retrospectively assessed. MRI examinations were performed using a 1.5-T scanner. A preload of paramagnetic contrast agent (gadolinium was administered 30 seconds before acquisition of dynamic images, followed by a standard dose 10 seconds after starting imaging acquisitions. The relative cerebral blood volume (rCBV values were determined by calculating the regional cerebral blood volume in the solid areas of lesions, normalized to that of the contralateral normal-appearing white matter. Discriminant analyses were performed to determine the cutoff point of rCBV values that would allow the differentiation of neoplastic from infectious lesions and to assess the corresponding diagnostic performance of rCBV when using this cutoff value. RESULTS: Neoplastic lesions had higher rCBV values (4.28±2.11 than infectious lesions (0.63±0.49 (p<0.001. When using an rCBV value <1.3 as the parameter to define infectious lesions, the sensitivity of the method was 97.8% and the specificity was 92.6%, with a positive predictive value of 91.8%, a negative predictive value of 98.0%, and an accuracy of 95.0%. CONCLUSION: PWI is a useful complementary tool in distinguishing between infectious and neoplastic brain

    To investigate the effect of rapid needle-out patient-rollover approach on the incidence of pneumothorax and drainage catheter placement due to pneumothorax in C-arm Cone-beam CT (CBCT)-guided percutaneous transthoracic needle biopsy (PTNB) of lung lesions. From May 2011 to December 2012, 1227 PTNBs were performed in 1191 patients with a 17-gauge coaxial needle. 617 biopsies were performed without (conventional-group) and 610 with rapid-rollover approach (rapid-rollover-group). Overall pneumothorax rates and incidences of pneumothorax requiring drainage catheter placement were compared between two groups. There were no significant differences in overall pneumothorax rates between conventional and rapid-rollover groups (19.8 % vs. 23.1 %, p = 0.164). However, pneumothorax rate requiring drainage catheter placement was significantly lower in rapid-rollover-group (1.6 %) than conventional-group (4.2 %) (p = 0.010). Multivariate analysis revealed male, age > 60, bulla crossed, fissure crossed, pleura to target distance > 1.3 cm, emphysema along needle tract, and pleural punctures ≥ 2 were significant risk factors of pneumothorax (p < 0.05). Regarding pneumothorax requiring drainage catheter placement, fissure crossed, bulla crossed, and emphysema along needle tract were significant risk factors (p < 0.05), whereas rapid-rollover approach was an independent protective factor (p = 0.002). The rapid needle-out patient-rollover approach significantly reduced the rate of pneumothorax requiring drainage catheter placement after CBCT-guided PTNB. (orig.)

    This study aims at testing the hypothesis that the Diagnostic and Statistical Manual of Mental Disorders fifth edition (DSM-5) alternative model of personality disorder (AMPD) traits may be significantly associated with deficits on 2 different social cognition tasks, namely, the Reading the Mind in the Eyes Test and the Movie for the Assessment of Social Cognition, in a sample of consecutively admitted inpatients and outpatients. The sample was composed of 181 consecutively admitted participants (57.5% women; mean age = 38.58 years). Correlation coefficients and partial correlation coefficients were computed in order to assess the associations among social cognition tasks, DSM-5 AMPD traits, and dimensionally assessed DSM-5 Section II personality disorders. Specific maladaptive traits listed in the DSM-5 AMPD were significantly associated with Reading the Mind in the Eyes Test scores and Movie for the Assessment of Social Cognition scores, even when the effect of selected DSM-5 Section II personality disorders was controlled for. Our results support the relevance of studying social cognitive functioning in subjects suffering from personality disorders. Copyright © 2017 John Wiley & Sons, Ltd.

    Three oral platelet P2Y12 inhibitors, clopidogrel, prasugrel, and ticagrelor, are available for reducing the risk of cardiovascular death and stent thrombosis in patients with acute coronary syndromes (ACS). We sought to compare the efficacy of these antiplatelet drugs in contemporary practice. Data were collected for 10 793 consecutive ACS patients undergoing coronary angiography at Sheffield, UK (2009-2015). Since prasugrel use was mostly restricted to the STEMI subgroup, clopidogrel and ticagrelor were compared for all ACS patients, and all three agents were compared in the STEMI subgroup. Differences in outcomes were evaluated at 12 months by KM curves and log-rank test after adjustment for independent risk factors. Of 10 793 patients with ACS (36% STEMI), 43% (4653) received clopidogrel, 11% (1223) prasugrel and 46% (4917) ticagrelor, with aspirin for all. In the overall group, ticagrelor was associated with lower all-cause mortality compared with clopidogrel (adjusted hazard ratio (adjHR) 0.82, 95% confidence intervals (CI) 0.71-0.96, p = 0.01). In the STEMI subgroup, both prasugrel and ticagrelor were associated with a lower mortality compared with clopidogrel (prasugrel vs. clopidogrel: adjHR 0.65, CI 0.48-0.89, p = 0.007; ticagrelor vs. clopidogrel: adjHR 0.70, CI 0.61-0.99, p = 0.05). Of the 7595 patients who underwent PCI, 78 (1.0%) had definite stent thrombosis by 12 months. Patients treated with ticagrelor had a lower incidence of definite stent thrombosis compared with clopidogrel (0.6% vs. 1.1%; adjHR 0.51, CI 0.29-0.89, p = 0.03). In the STEMI subgroup, there was no significant difference between the three groups (ticagrelor 1.0%, clopidogrel = 1.5%, prasugrel = 1.6%; p = 0.29). In conclusion, ticagrelor was superior to clopidogrel for reduction in both mortality and stent thrombosis in unselected invasively managed ACS patients. In STEMI patients, both ticagrelor and prasugrel were associated with lower mortality compared with clopidogrel, but

    Full Text Available Abstract Background A central venous catheter (CVC currently represents the most frequently adopted intravenous line for patients undergoing infusional chemotherapy and/or high-dose chemotherapy with hematopoietic stem-cell transplantation and parenteral nutrition. CVC insertion represents a risk for pneumothorax, nerve or arterial punctures. The aim of this prospective observational study was to explore the safety and efficacy of CVC insertion under ultrasound (US guidance and to confirm its utility in clinical practice in cancer patients. Methods Consecutive adult patients attending the oncology-hematology department were eligible if they had solid or hematologic malignancies and required CVC insertion. Four types of possible complication were defined a priore: mechanical, thrombotic, infection and malfunctioning. The patient was placed in Trendelenburg's position, a 7.5 MHZ puncturing US probe was placed in the supraclavicular site and a 16-gauge needle was advanced under real-time US guidance into the last portion of internal jugular vein. The Seldinger technique was used to place the catheter, which was advanced into the superior vena cava until insertion into right atrium. Within two hours after each procedure, an upright chest X-ray and ultrasound scanning were carried out to confirm the CVC position and to rule out a pneumotorax. CVC-related infections, symptomatic vein thrombosis and malfunctioning were recorded. Results From December 2000 to January 2009, 1,978 CVC insertional procedures were applied to 1,660 consecutive patients. The procedure was performed 580 times in patients with hematologic malignancies and 1,398 times those with solid tumors. A single-needle puncture of the vein was performed on 1,948 of 1,978 procedures (98.48%; only eighteen attempts among 1,978 failed (0.9%. No pneumotorax, no major bleeding, and no nerve puncture were reported; four cases (0.2% showed self-limiting hematomas. The mean lifespan of CVC was 189

    The objective of this study was to determine the long-term survivorship and clinical and radiographic results of the Scandinavian Total Ankle Replacement (STAR). From February 1996 to March 2000, seventy-seven ankles in seventy-two patients (thirty-seven female and thirty-five male patients, with an average age of fifty-six years) underwent total ankle replacement using the STAR prosthesis with a single coating of hydroxyapatite. Two patients were lost to follow-up, and twelve patients with thirteen ankle replacements died. The average duration of follow-up for the patients without revision was 12.4 years (range, 10.8 to 14.9 years). Sixty-two of the seventy-seven ankles were available for final follow-up. Twenty-nine (38%) of the seventy-seven ankles had a revision of at least one of the metallic components. The probability of implant survival was 70.7% at ten years and 45.6% at fourteen years. The main reasons for revision were aseptic loosening, subsidence of the talar component, and progressive cyst formation. Polyethylene insert fractures were observed in eleven ankles. While the midterm to short-term results for patients managed with the STAR prosthesis have been encouraging at 3.7 years, the long-term survivorship of the same cohort was considerably inferior. The subjective and clinical results of the patients with retained prostheses are generally good and comparable with results reported in the current literature.

    Full Text Available Introduction: The optimal treatment concept for temporary abdominal closure (TAC in critically ill visceral surgery patients with open abdomen (OA continues to be unclear. The VACM (vacuum-assisted closure and mesh-mediated fascial traction therapy seems to permit higher delayed primary fascial closure rates (FCR than other TAC procedures. Material and methods: Patients of our clinic (n=58 who were treated by application of a VAC/VACM treatment manual in the period from 2005 to 2008 were retrospectively analysed. Results: The overall FCR of all patients was 48.3% (95% confidence interval: 34.95–61.78. An FCR of 61.3% was achieved in patients who had a vicryl mesh implanted at the fascial level (VACM therapy in the course of treatment. Mortality among patients treated with VACM therapy was 45.2% (95% CI: 27.32–63.97.Conclusions: The results of our own study confirm the results of previous studies which showed an acceptable FCR among non-trauma patients who were treated with VACM therapy. VACM therapy currently appears to be the treatment regime of choice for patients with OA requiring TAC.

    objective: Among ovarian cancer patients, cancer treatment is aggressive and yet survival is often so limited; hence, this study sought to measure quality of life with the ultimate goal of identifying ways of improving it over the duration of these patients' lives. The medical records of all ovarian cancer patients who received some/all of their initial chemotherapy at the Mayo Clinic in Rochester, Minnesota from late 2010 through 2012 were reviewed. Patient-reported quality of life was derived from the following ten-point linear analogue scale questions which had been administered to all patients: 1) How would you describe your degree of pain, on average? 2) How would you describe your level of fatigue, on average? 3) How would you describe your overall quality of life? Quality of life data were censored upon cancer recurrence. Among 59 eligible patients, the median cumulative interval during which quality of life was serially assessed was 1.15 years (range: three months, 3.2 years). Area under the curve for pain, fatigue, and global quality of life showed no statistically significant differences between patients treated with dose-dense chemotherapy with carboplatin/paclitaxel (n = 10) versus three-week chemotherapy with carboplatin/paclitaxel (n = 36) versus other (n = 13). Although pain, fatigue, and global quality of life improved over time, 35 of 59 (59%) patients reported grade 4 or worse pain during follow up, and 47 of 59 (80%) reported grade 4 or worse fatigue (higher scores denote worse pain or fatigue). After completion of cancer treatment, 30 (51%) described grade 4 or worse pain or fatigue. The most common pain site was the abdomen/pelvis, followed by the back, followed by the hands, feet, fingers, and toes. In ovarian cancer patients who remain cancer-free, severe pain and fatigue occur years after cancer treatment. Further research should focus on how best to address these symptoms.

    Purpose Emerging evidence shows that positive airway pressure (PAP) treatment of obstructive sleep apnea (OSA) and upper airway resistance syndrome (UARS) in chronic insomnia patients (proposed “complex insomnia” disorder) leads to substantial decreases in insomnia severity. Although continuous PAP (CPAP) is the pressure mode most widely researched, intolerance to fixed pressurized air is rarely investigated or described in comorbidity patients. This retrospective study examined dual pressure, autoadjusting PAP modes in chronic, complex insomnia disorder patients. Patients and methods Chronic insomnia disorder patients (mean [SD] insomnia severity index [ISI] =19.11 [3.34]) objectively diagnosed with OSA or UARS and using either autobilevel PAP device or adaptive servoventilation (ASV) device after failing CPAP therapy (frequently due to intolerance to pressurized air, poor outcomes, or emergence of CSA) were divided into PAP users (≥20 h/wk) and partial users (insomnia patients, PAP users (n=246) averaged 6.10 (1.78) nightly hours and 42.71 (12.48) weekly hours and partial users (n=56) averaged 1.67 (0.76) nightly hours and 11.70 (5.31) weekly hours. For mean (SD) decreases in total ISI scores, a significant (group × time) interaction was observed (F[1,300]=13.566; Pinsomnia symptoms (r=−0.256, PInsomnia severity significantly decreased in patients using autoadjusting PAP devices, but the study design restricts interpretation to an association. Future research must elucidate the interaction between insomnia and OSA/UARS as well as the adverse influence of pressure intolerance on PAP adaptation in complex insomnia patients. Randomized controlled studies must determine whether advanced PAP modes provide benefits over standard CPAP modes in these comorbidity patients. PMID:28331381

    Full Text Available We aimed to reveal the true status of epidermal growth factor receptor (EGFR mutations in Chinese patients with non-small cell lung cancer (NSCLC after lung resections. EGFR mutations of surgically resected fresh tumor samples from 697 Chinese NSCLC patients were analyzed by Amplification Refractory Mutation System (ARMS. Correlations between EGFR mutation hotspots and clinical features were also explored. Of the 697 NSCLC patients, 235 (33.7% patients had tyrosine kinase inhibitor (TKIs sensitive EGFR mutations in 41 (14.5% of the 282 squamous carcinomas, 155 (52.9% of the 293 adenocarcinomas, 34 (39.5% of the 86 adenosquamous carcinomas, one (9.1% of the 11 large-cell carcinomas, 2 (11.1% of the 18 sarcomatoid carcinomas, and 2 (28.6% of the 7 mucoepidermoid carcinomas. TKIs sensitive EGFR mutations were more frequently found in female patients (p < 0.001, non-smokers (p = 0.047 and adenocarcinomas (p < 0.001. The rates of exon 19 deletion mutation (19-del, exon 21 L858R point mutation (L858R, exon 21 L861Q point mutation (L861Q, exon 18 G719X point mutations (G719X, including G719C, G719S, G719A were 43.4%, 48.1%, 1.7% and 6.8%, respectively. Exon 20 T790M point mutation (T790M was detected in 3 squamous carcinomas and 3 adenocarcinomas and exon 20 insertion mutation (20-ins was detected in 2 patients with adenocarcinoma. Our results show the rates of EGFR mutations are higher in all types of NSCLC in Chinese patients. 19-del and L858R are two of the more frequent mutations. EGFR mutation detection should be performed as a routine postoperative examination in Chinese NSCLC patients.

    Objectives: This study examined patterns of recurrence after low–dose-rate prostate brachytherapy (LDR-PB), estimated local recurrence rate and compared that rate to the estimated local recurrence rate after radical prostatectomy (RP). Methods and Materials: A prospective database was maintained with clinical, dosimetric, and outcome data for all LDR-PB implantation procedures performed at our institution. From 1998 to 2008, 2223 patients with prostate cancer received LDR-PB without supplemental external beam radiation therapy. Patients who developed Phoenix-defined biochemical failure were reviewed for sites of relapse and investigations completed. Results: At a median follow-up of 5 years, 108 of 2223 patients (4.8%) developed biochemical relapse. In 1 additional patient, local relapse was found on transurethral prostate resection, but his prostate-specific antigen concentration was well short of triggering Phoenix-defined failure. Of the 109 patients with disease relapse, 18 of 2223 (0.8%) had a proven local recurrence, and 30 of 2223 (1.3%) had a proven distant recurrence. The remaining 61 of 2223 patients (2.7%) had unidentified sites of recurrence; of these, 57 patients (93%) had digital rectal examinations (DREs), 18 (30%) had post-treatment biopsies, 45 (74%) had bone scans, and 34 (56%) had computed tomography imaging of the abdomen and pelvis. If every biochemical failure were local, the local recurrence rate would be as high as 4.9%; however, by excluding those with proven distant failure and those with both a negative DRE and biopsy, we estimate that the local recurrence rate is 2.7% or less. Conclusions: In the context of limitations of the study design, our population-based analysis indicates that the local recurrence rate after LDR-PB is as low or lower than that after RP in our jurisdiction.

    Objectives Renal involvement in scrub typhus ranges from simple urinary abnormalities to acute kidney injury (AKI) leading to death. This study evaluated the incidence, predictors and prognosis of AKI associated with scrub typhus according to the RIFLE (risk, injury, failure, loss, end-stage kidney disease) criteria. Methods We retrospectively evaluated the medical records of patients diagnosed with scrub typhus from January 2001 to November 2013 in Gyeongsang National University Hospital. Results During the study period, 510 patients were diagnosed with scrub typhus and the incidence of AKI was 35.9%. There were 132 (25.9%) patients at risk, 37 (7.3%) with injury and 14 (2.7%) with failure. In comparison with the non-AKI group, the AKI group was older (73.9 vs 63.4 years, pIntensive care unit admission and death were more frequent in the AKI group. The renal function of most patients with AKI recovered without sequelae, except for 1 patient who had underlying CKD. Multivariate analysis showed that age, presence of CKD, serum albumin level and time to hospital presentation after symptom onset were independent predictors of AKI in patients with scrub typhus. Conclusions Our current results suggest that the presence of underlying CKD, older age, lower serum albumin level and time to hospital presentation after symptom onset were important risk factors to determine occurrence of AKI. Whether earlier diagnosis and treatment in patients with the above risk factors reduce the incidence and severity of AKI deserves to be investigated. PMID:28298367

    Controversy exists as to the most effective management option for elderly patients with type II odontoid fractures. The purpose of this study is to evaluate outcomes associated with rigid cervical collar and posterior fusion surgery. Patients with ≥ 50% odontoid displacement were treated with posterior fusion surgery including C1-2 (PSF group, n = 25, average age = 80 years). Patients with cervical collar for 12 weeks (collar group, n = 33, average age = 83 years). These inhomogeneous groups were followed for an average of 14 months. Fracture healing rates were higher in the operative group (28% versus 6%). Neck Disability Index scores were slightly lower in the nonoperative group (13 versus 18.3, p = 0.23). Analogue pain scores were also slightly lower in the nonoperative group (1.3 versus 1.9, p = 0.26). The mortality rate was 12.5% in the collar group and 20% in the operative group. Complications were higher in the operative group (24% versus 6%). Rates of type II odontoid facture healing and stability appear to be higher in geriatric patients treated with posterior fusion surgery. Fracture healing and stability did not correlate with improved outcomes with respect to levels of pain, function, and satisfaction. Mortality and complication rates are lower in those patients with lesser-displaced fractures who are treated with a cervical collar and early mobilization.

    2014-11-01

    Full Text Available Introduction:  Insulin-like growth factor 1 (IGF-1 is a key peptide involved in cell growth and protein turnover, acting as the primary mediator of many of the responses regulated by growth hormone (GH in tissues. Signs and symptoms of adult GH deficiency (AGHD in patients with β-thalassaemia major (TM  may be subtle and overlap with those of the disease itself; therefore, the diagnosis may be missed or delayed, with potentially serious consequences. The diagnosis of AGHD requires an appropriate clinical setting and is confirmed through biochemical testing. The  aim of this study  was  to measure IGF-1 values and other clinical data in a large number of adult  patients with TM and to  evaluate whether an  IGF-1 concentration 2 SDs below normative values  could be used as an effective index supporting  the probable presence of  AGHD. Patients and Methods: A cohort of 120 adult patients with TM was studied for plasma levels of IGF-1. Plasma total IGF-1 was determined by chemiluminescent immunometric assay (CLIA method. In eleven patients (4 males the GH response during glucagon stimulation test (GST was also evaluated.  Results:  Fifty percent of patients (33 males and 27 females had IGF-1 levels   -2SDs. In multivariate regression analyses,  height, weight, BMI, serum ferritin, ALT, HCV serology and left ventricular ejection fraction (LVEF were not significantly related to IGF-1,  but a significant correlation was found in females between HCV-RNA positivity and IGF-1, ALT and serum ferritin (p= 0.043. AGHD was diagnosed in 6 (4 males out of 11 patients (54.5% who had glucagon stimulation tests and in 5 out of 8 (62.5% with IGF-1 <-2SD. The mean age of patients with GHD was 39.3 years (range: 25-49 years versus 35.8 years (range: 27-45 years in non-GHD patients. A positive correlation between GH peak after GST and IGF-1 level was found (r: 0.6409; p: < 0.05. Conclusions: On the basis of the present results and data from the

    The prevalence of MLH1 constitutional epimutations in the general population is unknown. We sought to analyse the prevalence of MLH1 constitutional epimutations in unselected and selected series of patients with colorectal cancer (CRC). Patients with diagnoses of CRC (n=2123) were included in the unselected group. For comparison, a group of 847 selected patients with CRC who fulfilled the revised Bethesda guidelines (rBG) were also included. Somatic and constitutional MLH1 methylation was assayed via methylation-specific multiplex ligation-dependent probe amplification of cases lacking MLH1 expression. Germline alterations in mismatch-repair (MMR) genes were assessed via Sanger sequencing and methylation-specific multiplex ligation-dependent probe amplification. Loss of MLH1 expression occurred in 5.5% of the unselected series and 12.5% of the selected series (pprevalence of MLH1 constitutional epimutations in unselected cases of CRC. Therefore, MLH1 constitutional epimutation analysis should be conducted only for patients who fulfil the rBG and who lack MLH1 expression with methylated MLH1.

    Full Text Available Background: Percutaneous closure of patent ductus arteriosus (PDA with Amplatzer duct occluder (ADO has become increasingly popular in many cardiovascular centres. This study analysed the long-term results of percutaneous closure of PDA with ADO in a single centre. Materials and Methods: Between May 2004 and January 2013, 243 patients with median age of 2.5 years (range = 30 months to 38 years and median weight of 10 Kg (range 4.5-80.5 Kg underwent percutaneous closure of PDA using the ADO. The devices were implanted under fluoroscopic guidance. Patients were followed-up for any complications. Results: The mean diameter of narrow part of PDA was 6.4 ± 2.2 mm. The mean diameter of devices was 7.8 ± 2.3 mm. The devices were successfully implanted in 239 (98.3% cases. At immediate, 1 day, 1, 6, 12 months and late follow-up, the complete occlusion rate was 33% (79 case, 97.1% (236 case, 97.5% (237 case, 98.3% (238 case, 98.3% (238 case and 98.3% (238 case, respectively. Residual shunt remained in one case at late follow-up. The device embolisation occurred in five patients. The devices were successful retrieved in three patient and second larger devices were inserted. Two other devices were surgically retrieved and PDAs were ligated. Moderate left pulmonary artery stenosis (LPA in one child and mild LPA stenosis in one infant were detected. Mild aortic obstruction occurred in one infant. Conclusions: Long-term follow-up of patients indicate that percutaneous closure of PDA using ADO is a safe and effective procedure. However, some complications, including device embolisation, left pulmonary stenosis and aortic obstruction may be observed in some cases.

    To present the various complications of ultrasound (US)-guided core needle biopsy (CNB) of thyroid lesions in a large patient series. From January 2008 to March 2013, 6,169 patients underwent US-guided CNB of 6,687 thyroid nodules at a single institution. We assessed the number and types of major and minor complications, and evaluated the factors associated with complications. Overall, 53 complications were observed in 50 patients (0.81 %), including 4 major and 49 minor complications. The major complications were massive haematoma (n = 2), pseudoaneurysm (n = 1) and voice change leading to disability that lasted for more than 30 days (n = 1). The minor complications were small to moderate haematoma (n = 42), carotid injury (n = 2), voice change that recovered within 30 days (n = 3), tracheal puncture (n = 1) and dysphagia (n = 1). Oedema (n = 12), vertebral puncture (n = 3) and vasovagal reaction (n = 1) were recorded as side effects. The presence of a coprocedure was the only significant factor associated with complications after thyroid CNB (P = 0.023). US-guided CNB of thyroid lesions was found in a large population to be a safe procedure with a low complication rate. • The complication rate after US-guided CNB for thyroid lesions was 0.81 % (50/6,169). • The rate of major complications was 0.06 % (4/6,169). • Vascular injury was the most common complication (47/6,169; 0.76 %). • None of the patients experienced permanent problems resulting from complications.

    The medial protrusio technique may be used during total hip arthroplasty (THA) on patients with developmental dysplasia. However, studies have yet to determine whether a cementless cup can be sufficiently stable to withstand loading forces. This study aimed to assess the clinical and radiographic outcomes of this technique. Furthermore, we sought to determine the relationship between the rate of medial protrusion and the incidence of cup loosening. Thirty-nine patients (43 hips) underwent cementless THA between April 2006 and March 2009 by using the medial protrusio technique. These patients participated in a 6- to 9-year follow-up. Their clinical and radiographic data were gathered prospectively. The average Harris Hip Score improved from 43.1 ± 15.4 points preoperatively to 91.9 ± 12.8 points at the final follow-up (P hip center and the distance of hip center medialization were 2.4 ± 0.6 and 2.5 ± 0.9 cm, respectively. The rate of medial protrusion and the rate of cup coverage were 42.1 ± 12.4% and 96.8 ± 5.1%, respectively. The rate of medial protrusion ranged from 18.3% to 58.3% in 38 hips (group A) and from 61.3% to 68.9% in 5 hips (group B). None of the cups in group A loosened or failed, 2 failures occurred in group B (0% vs 40.0%; P = .011). Developmental dysplasia was treated through THA using the medial protrusio technique, which easily achieves a sufficient superolateral host bony coverage of the cup and promotes socket reconstruction at the true acetabulum. The rate of medial protrusion of <60% may be necessary to obtain excellent clinical and radiographic midterm results. Copyright © 2016 Elsevier Inc. All rights reserved.

    Physiologic monitors are plagued with alarms that create a cacophony of sounds and visual alerts causing "alarm fatigue" which creates an unsafe patient environment because a life-threatening event may be missed in this milieu of sensory overload. Using a state-of-the-art technology acquisition infrastructure, all monitor data including 7 ECG leads, all pressure, SpO(2), and respiration waveforms as well as user settings and alarms were stored on 461 adults treated in intensive care units. Using a well-defined alarm annotation protocol, nurse scientists with 95% inter-rater reliability annotated 12,671 arrhythmia alarms. A total of 2,558,760 unique alarms occurred in the 31-day study period: arrhythmia, 1,154,201; parameter, 612,927; technical, 791,632. There were 381,560 audible alarms for an audible alarm burden of 187/bed/day. 88.8% of the 12,671 annotated arrhythmia alarms were false positives. Conditions causing excessive alarms included inappropriate alarm settings, persistent atrial fibrillation, and non-actionable events such as PVC's and brief spikes in ST segments. Low amplitude QRS complexes in some, but not all available ECG leads caused undercounting and false arrhythmia alarms.

    Full Text Available PURPOSE: Physiologic monitors are plagued with alarms that create a cacophony of sounds and visual alerts causing "alarm fatigue" which creates an unsafe patient environment because a life-threatening event may be missed in this milieu of sensory overload. Using a state-of-the-art technology acquisition infrastructure, all monitor data including 7 ECG leads, all pressure, SpO(2, and respiration waveforms as well as user settings and alarms were stored on 461 adults treated in intensive care units. Using a well-defined alarm annotation protocol, nurse scientists with 95% inter-rater reliability annotated 12,671 arrhythmia alarms. RESULTS: A total of 2,558,760 unique alarms occurred in the 31-day study period: arrhythmia, 1,154,201; parameter, 612,927; technical, 791,632. There were 381,560 audible alarms for an audible alarm burden of 187/bed/day. 88.8% of the 12,671 annotated arrhythmia alarms were false positives. Conditions causing excessive alarms included inappropriate alarm settings, persistent atrial fibrillation, and non-actionable events such as PVC's and brief spikes in ST segments. Low amplitude QRS complexes in some, but not all available ECG leads caused undercounting and false arrhythmia alarms. Wide QRS complexes due to bundle branch block or ventricular pacemaker rhythm caused false alarms. 93% of the 168 true ventricular tachycardia alarms were not sustained long enough to warrant treatment. DISCUSSION: The excessive number of physiologic monitor alarms is a complex interplay of inappropriate user settings, patient conditions, and algorithm deficiencies. Device solutions should focus on use of all available ECG leads to identify non-artifact leads and leads with adequate QRS amplitude. Devices should provide prompts to aide in more appropriate tailoring of alarm settings to individual patients. Atrial fibrillation alarms should be limited to new onset and termination of the arrhythmia and delays for ST-segment and other parameter

    AIM: To evaluate the suitability of percutaneous drainage as a primary and definitive treatment of hydatid disease of the liver. MATERIALS AND METHODS: Between October 1989 and April 1992, percutaneous drainage was performed on 52 consecutive patients (27 women and 25 men aged 13 to 84 years) with 55 hydatid cysts in the liver. Twenty-five (45%) cysts were type I, 10 (18%) were type II, 14 (25%) were type III, 5 (10%) were type IV and 1 (2%) was type V. All procedures were performed under light sedation and local anaesthetic at the puncture site. The standard Seldinger technique was used. Initial puncture was performed under ultrasound (US) guidance through the liver parenchyma. The rest of the procedure was conducted under fluoroscopic control. Pigtail drainage catheters (size 12-20 Fr) were used, with Betadine (10% povidone iodine; 1% free iodine) being allowed to act within the cyst for 30 min, as a scolicidal agent. RESULTS: All the patients were successfully treated and 6-9 year follow-up involving US, computed tomography (CT) and serology tests showed no local recurrence or spread of the disease. No major (death, cyst rupture, anaphylactic shock) and very few minor complications arose. Two patients had mild skin reaction with nausea requiring no treatment and three patients developed a secondary infection of the cyst, due to prolonged drainage time. These liver abscesses responded successfully to further catheter drainage. Subsequent patients were treated with large bore (18-20 Fr) catheters and none developed secondary infection. Overall drainage time varied from 7-118 days (7-28 days, if we exclude three initial cases who had prolonged drainage). CONCLUSION: It is our strong belief that percutaneous drainage using the above method should be considered a first-line treatment for hydatid disease of the liver. Bosanac, Z.B., Lisanin, L. (2000)

    Aims Infection is a serious complication of pacemaker (PM) systems. Although the rate of infection has been debated, the figures are largely unknown. We therefore studied the incidence of PM infection and its associated risk factors in the Danish population. Methods and results Since 1982, all PM implantation and removal procedures performed in Denmark have been prospectively recorded in the Danish Pacemaker Register. All patients (n = 46299) who underwent implantation between 1982 and 2007 were included. The total length of surveillance was 236 888 PM-years. The incidence of infection was calculated according to the total number of PM-years. The incidence of surgical site infection (≤365 days after PM implantation) was compared with later infection in first implant and replacement procedures. Multiple-record and multiple-event-per-subject proportional hazards analyses were used to identify the independent risk factors of PM infection. Surgical site infection occurred in 192 cases after first implantation (incidence rate 4.82/1000 PM-years), and in 133 cases after replacement (12.12/1000 PM-years). Infections occurring more than 365 days after the first implantation occurred in 153 cases (1.02/1000 PM-years), and in 118 cases after replacement (3.26/1000 PM-years). Independent factors associated with an increased risk of PM infection were a greater number of PM operations (including replacements), male sex, younger age, implantation during the earliest part of the study period, and absence of antibiotics (P< 0.001). Conclusion The overall risk of infection after PM implantation was low. A greater number of operations augmented the risk of infection. This should be taken into account when considering revisions of PM systems. PMID:21252172

    In the last decade, costs of U.S. healthcare expenditures have been soaring, with billions of dollars spent on hospital readmissions. Identifying causes and risk factors can reduce soaring readmission rates and help lower healthcare costs. The aim of this is to determine if post-operative delirium in the elderly is an independent risk factor for 30-day hospital readmission after spine surgery. The medical records of 453 consecutive elderly (≥65years old) patients undergoing spine surgery at Duke University Medical Center from 2008 to 2010 were reviewed. We identified 17 (3.75%) patients who experienced post-operative delirium according to DSM-V criteria. Patient demographics, comorbidities, and post-operative complication rates were collected for each patient. Elderly patients experiencing post-operative delirium had an increased length of hospital stay (10.47days vs. 5.70days, p=0.009). Complication rates were similar between the cohorts with the post-operative delirium patients having increased UTI and superficial surgical site infections. In total, 12.14% of patients were re-admitted within 30-days of discharge, with post-operative delirium patients experiencing approximately a 4-fold increase in 30-day readmission rates (Delirium: 41.18% vs. No Delirium: 11.01%, p=0.002). In a multivariate logistic regression analysis, post-operative delirium is an independent predictor of 30-day readmission after spine surgery in the elderly (p=0.03). Elderly patients experiencing post-operative delirium after spine surgery is an independent risk factor for unplanned readmission within 30-days of discharge. Preventable measures and early awareness of post-operative delirium in the elderly may help reduce readmission rates.

    Study Design. Multi-center, prospective analysis of consecutive ASD patients.Objective. Evaluate complications associated with rhBMP-2 use in ASDSummary of Background Data. Off-label rhBMP-2 use is common, however under-reporting of rhBMP-2 associated complications has been recently scrutinized.Methods. ASD patients consecutively enrolled into a prospective, multicenter database, were evaluated for type and timing of acute perioperative complications. Inclusion criteria: age ≥ 18 years, ASD, spinal arthrodesis >4 levels, and ≥3 months follow-up. Patients divided into those receiving rhBMP-2 (BMP) or no rhBMP-2 (NOBMP). BMP divided into location of use: posterior (PBMP), interbody (IBMP), and interbody + posterior spine (I+PBMP). Correlations between acute perioperative complications and rhBMP-2 use including total dose, dose/level and location of use were evaluated.Results. 279 patients (mean age 57 years, mean spinal levels fused 12.0, mean follow-up 28.8 months) met inclusion criteria. BMP (n = 172; average posterior dose = 2.5 mg/level, average interbody dose = 5 mg/level) had similar age, smoking history, previous spine surgery, total spinal levels fused, estimated blood loss, and duration of hospital stay as NOBMP (n = 107; p>0.05). BMP had greater Charlson Comorbidity Index (1.9 vs. 1.2), greater scoliosis (43° vs. 38°), longer operative time (488.2 vs. 414.6 minutes), more osteotomies/patient (4.0 vs. 1.6) and greater percentage of anteroposterior fusion (APSF; 20.9% vs. 8.4%) than NOBMP, respectively (p0.05). Multivariate analysis demonstrated small to non-existent correlations between rhBMP-2 use and complications.Conclusions. RhBMP-2 use and location of rhBMP-2 use in ASD surgery, at reported doses, does not increase acute major, neurological or wound complications. Research is needed for higher rhBMP-2 dosing and long-term follow-up.

    Medication-related osteonecrosis of the jaw (ONJ) is often preceded by dentoalveolar trauma. The aim of this study was to examine the frequency of dentoalveolar trauma precipitated ONJ and compare trauma-precipitated ONJ with spontaneously developing ONJ. This was a retrospective study. All patients were examined according to a standard ONJ chart. Among 149 consecutive ONJ patients from the Copenhagen Cohort, 95 (64%) had a dentoalveolar trauma before referral (trauma group): dental extractions (n = 80); denture-related sore mouth (n = 12); and others (n = 3). The remaining 54 patients had spontaneous ONJ (spontaneous group). The mean time from oral trauma to referral for ONJ was 8 months. This study documented that dentoalveolar trauma precipitated ONJ in the majority of cases. However, even minor trauma, such as intubation and impression tray lesions, precipitated ONJ in a few cases (1%). Besides the occurrence of fistula to the skin and a difference in the male-to-female ratio, we found no significant difference between the spontaneous and trauma groups.

    Borderline ovarian tumours are semimalignant tumours occurring unilaterally or bilaterally with a peak incidence among women of reproductive age. Since the affected women often wish to preserve fertility, particular precautions must be taken when counselling the patient and obtaining consent prior to planning an individual treatment. Options for preserving fertility include an organ-sparing surgical procedure and cryopreservation of oocytes and/or ovarian tissue. In this article, we report on a 25-year-old patient with a bilateral seromucinous borderline tumour who desired all fertility-preserving options. In order to perform the procedure without delay, we opted to perform luteal phase stimulation prior to oocyte retrieval. We conclude by discussing the current literature on the state of fertility preservation in the treatment of borderline ovarian tumours.

    To determine the long-term outcome after fusion for adolescent idiopathic scoliosis in terms of degenerative disc findings diagnosed using MR imaging and to elucidate the clinical consequences. Material and methods: Thirty-two patients with adolescent idiopathic scoliosis, who had undergone spinal fusion using Harrington rods to the lower lumbar spine with one or two unfused discs below the fusion, were re-examined 25 years after the fusion. The re-examinations included validated questionnaires, clinical examination, full standing frontal and lateral radiographs and MR examination of the lower lumbar region. Curve size and degenerative findings on MR images were evaluated by two unbiased radiologists, blinded to the clinical findings. A matched control group of 32 persons without scoliosis was subjected to the same examinations. Results and conclusion: There were significantly more degenerative disc changes (p<0.0001), disc height reduction (p=0.0010) and end-plate changes (p<0.0001 for both upper and lower end-plates) in the lowest unfused disc in the patient group compared with the control group. The MR findings in the lowest unfused disc, but not the one above, in the patient group correlated to lumbar pain intensity as well as to the diminished lumbar lordosis.

    Purpose: To evaluate the metabolic response of uterine cervix and pelvic lymph nodes (LNs) using consecutive {sup 18}F-fluorodeoxyglucose-positron emission tomography/computed tomography (PET/CT) immediately after RT and to correlate survival outcome with the metabolic response. Methods and Materials: We retrospectively reviewed 48 patients with cervical cancer who had positive pelvic LNs by preradiation therapy (pre-RT) PET/CT. All patients underwent PET/CT scans immediately after RT (inter-RT PET/CT) after median 63 Gy to the gross LNs. The metabolic response of the LNs was assessed quantitatively and semiquantitatively by measurement of the maximal standardized uptake value (SUV{sub max}). Results: Classifying the metabolic response of all nodal lesions, 37 patients (77%) had LNs with complete metabolic response on the inter-RT PET/CT (LNCMRi), and 11 patients had a non-LNCMRi, including 4 patients with progressive metabolic disease. The overall 3-year survival rates were 83% for the patients with LNCMRi and 73% for the non-LNCMRi group (P=.038). The disease-free survival for patients with LNCMRi were significantly better than that for the non-LNCMRi group (71% vs 18%, respectively, P<.001). The 3-year distant metastasis-free survival rates were 79% for the patients with LNCMRi and 27% for the non-LNCMRi group (P<.001). There were no statistically significant differences in overall survival (76% vs 86%, respectively, P=.954) and disease-free survival rates (58% vs 61%, respectively, P=.818) between the CMR of primary cervical tumor and the non-CMR groups. Conclusions: The results showed a significant correlation between survival outcome and the interim metabolic response of pelvic LNs. CMR of nodal lesion on inter-RT PET/CT had excellent overall survival, disease-free survival and distant metastasis-free survival rates. This suggested that PET/CT immediately after RT can be a useful tool for the evaluation of the interim response of the LNs and identify a subset

    To perform a quantitative analysis of choroidal thickness in patients with Fuchs Uveitis Syndrome (FUS) using enhanced depth imaging optical coherence tomography (EDI-OCT). All patients underwent comprehensive ophthalmic examination, including best-corrected visual acuity, slit-lamp biomicroscopy, applanation tonometry, axial length measurements with a swept-source biometer (IOLMaster 700, Carl Zeiss Medic AG, Jena, Germany) and macular 30° linear EDI- B-scan SD-OCT section (Spectralis HRAII+OCT, Heidelberg Engineering, Heidelberg, Germany) in both eyes. Analysis of choroidal thickness was performed at three different locations: subfoveally, 750 μm nasally, and 750 μm temporally to the fovea. Patients having received any surgery or intravitreal injections in the last 12 months and with axial length variance ≥ 1 mm between both eyes were excluded. Sixteen eyes of eight consecutive patients with unilateral FUS were included. Segmented analysis of the choroid, separately considering Haller's layer and Sattler's-choriocapillaris layers, showed statistically significant lower values (p choroidal thickness mean values ranged from 305.62 ± 92.96 μm to 347.50 ± 91.55 μm; in FEs those values were significantly lower (p thickness choroidal thinning in FEs was observed. Considering the absence of significant axial length differences between FEs and NFEs in our patient series, these data seem to suggest that the full-thickness choroidal thinning in FEs may be due to the inflammatory process. In that way, FUS might be regarded as an inflammatory condition involving the whole uveal tunic, even the posterior part of it, definitively supplanting the early definition of "heterochromic iridociclytis".

    To the best of our knowledge, this is the first study to evaluate the predictive value of free air (on a plain radiograph) for bowel perforation in a large prospective cohort of surgical patients. All consecutive patients undergoing abdominal surgery between January 2011 and June 2012 were screened for this study. We performed an upright chest radiograph on the second and third postoperative day. Thereafter, additional radiographic evaluations were performed every 2 days until the disappearance of abdominal free air. Of the 648 subjects enrolled in our study, free abdominal air was found in 65 subjects on the first radiographic evaluation (2 days after surgery), 51 on the second (3 days after surgery), three on the third (5 days after surgery), and none on the fourth (7 days after surgery). The presence of free abdominal air was associated with an increased risk of gastrointestinal perforation. The presence of free air was associated with a hazard ratio (HR) of 21.54 (95% CI 9.66-48.01, pSensitivity, specificity, positive predictive value, and negative predictive value were 70, 93, 33, and 98%, respectively, at 2 days after surgery, and similar results were confirmed at 3 days after surgery. We believe that the presence of free air at 3 days after surgery should not be considered a common finding. Here, we demonstrate that the detection of free air has a remarkable predictive value for gastrointestinal perforation, which has been overestimated in previous experience.

    Full Text Available Customized patient instrumentation (CPI combines preoperative planning with customized cutting jigs to position and align implants during total knee arthroplasty (TKA. We compared postoperative implant alignment of patients undergoing surgery with CPI to traditional TKA instrumentation for accuracy of implant placement. Twenty-five consecutive TKAs using CPI were analyzed. Preoperative CT scans of the lower extremities were segmented using a computer program. Limb alignment and mechanical axis were computed. Virtual implantation of computer-aided design models was done. Postoperative coronal and sagittal view radiographs were obtained. Using 3D image-matching software, relative positions of femoral and tibial implants were determined. Twenty-five TKAs implanted using traditional instrumentation were also analyzed. For CPI, difference in alignment from the preoperative plan was calculated. In the CPI group, the mean absolute difference between the planned and actual femoral placements was 0.67° in the coronal plane and 1.2° in the sagittal plane. For tibial alignment, the mean absolute difference was 0.9° in the coronal plane and 1.3° in the sagittal plane. For traditional instrumentation, difference from ideal placement for the femur was 1.5° in the coronal plane and 2.3° in the sagittal plane. For the tibia, the difference was 1.8° in the coronal plane. CPI achieved accurate implant positioning and was superior to traditional TKA instrumentation.

    A new method in creating 3D models of the left atrium (LA) and esophagus before catheter ablation of atrial arrhythmias is 3D rotational angiography (3DRA) of the LA. The purpose of this retrospective study was to test various acquisition protocols of the 3DRA and attempt to define the parameters influencing the success of the protocols. From August 2010 to November 2014, 3DRA of the LA using the Philips Allura FD 10 X-ray system was performed in 547 consecutive patients using right atrial and left atrial protocols. Visualization of the esophagus was performed after oral administration of a contrast agent. Patients were monitored for success (creation of a useful 3D models) and evaluated for a number of parameters affecting the success of 3DRA. The success of the RA protocol was 88.89 % with and 91.91 % without esophagus imaging. The success of the LA protocol was 97.42 % with and 94.54 % without esophagus imaging. The only factor reducing the success of the RA protocol was BMI; the LA protocol was not influenced by any factor. Ventricular fibrillation induced in two patients was successfully treated with defibrillation. 3DRA of the LA is a reliable method that supports catheter ablation of complex atrial arrhythmias. The LA protocol with esophagus imaging was significantly more reliable than the RA protocol; the other protocols were comparable. The RA protocol may be negatively affected by high BMI. Simultaneous imaging of the esophagus is safe and feasible, and the LA protocol can be recommended.

    Acromegaly is characterized by a persistent hypersecretion of GH and provides information on long-term effects of GH on bone metabolism. The aim of this study was to examine the effect of gonadal status and disease activity on bone metabolism in active acromegaly. Seventy-three consecutive patients with active acromegaly: 40 women and 33 men (50 +/- 13 (mean +/- s.d.) and 49 +/- 10 years respectively) were evaluated and compared with age-, sex-, and body mass index (BMI)-matched controls by X-ray absorptiometry and biochemical analysis (markers of disease activity and bone turnover). We found that bone turnover, as evaluated by biochemical bone markers, is coupled and markedly increased in relation to disease activity in active acromegaly. Acromegalic women, but not men, were characterized by an increased bone area and slightly decreased bone mineral content resulting in significantly decreased bone mineral density (BMD) in the ultradistal radius, proximal radius, and total body. No differences in bone turnover or BMD were found between eu-and hypogonadal subjects. Multivariate analysis identified age, BMI, and gender as independent predictors of total BMD in acromegaly. Our study demonstrates a decreased total body BMD in women, not men, with active acromegaly, regardless of gonadal status or disease activity. Bone turnover is markedly increased in relation to disease activity, possibly counteracting the anabolic effects of excess GH/IGF-I in these subjects. We suggest more focus on biomechanical analyses when investigating endocrine disorders affecting bone size and distribution between compartments.

    Purpose: prospective evaluation of vertebroplasty for osteoporotic compression fractures concerning pain reduction, demand of analgesics and quality of life. Material and Methods: in 26 consecutive patients, 50 vertebral fractures were treated by percutaneous vertebroplasty under fluoroscopic (n = 44) or combined fluoroscopic/CT guidance (n = 6). Prospective follow-up was performed after 6 (for 50 vertebral fractures) and 12 months (for 27 vertebral fractures). Visual analogue scale (VAS) and numeric rating scale (NRS) was applied for the assessment of pain. Subjective quality of life and analgesics demand was documented semi-quantitatively. Results: mean interval from the beginning of pain symptoms to therapy was 8.5 weeks. Vertebroplasty was technically successful in all evaluated patients. Pain severity decreased from 10 (defined at baseline as initial pain score) to 2.8 after 6 months and 2.7 after 12 months. Subjective quality of life was reported as very well, well or improved in 92% (n = 26 after 6 months) or 100% (n = 13 after 12 months). No need for additional analgesic therapy was observed in 69.3% (n = 26) after 6 months and 61.5% (n = 13) after 12 months. Eight newly developed vertebral fractures were observed during follow-up, with 5 fractures directly adjacent to previously treated vertebrae. Leakage of polymethyl methacrylate (PMMA) into the intervertebral space or spinal canal was observed in 22% and 20% respectively (n = 50 vertebrae). No neurologic deterioration or complications requiring surgery were observed. Conclusion: vertebroplasty is a successful therapeutic approach for the treatment of osteoporotic vertebral fractures. Persistent improvement of clinical symptoms was shown at follow-up after 6 and 12 months. (orig.)

    The Lick planet search program began in 1987 when the first spectrum of $\\tau$ Ceti was taken with an iodine cell and the Hamilton Spectrograph. Upgrades to the instrument improved the Doppler precision from about 10 m/s in 1992 to about 3 m/s in 1995. The project detected dozens of exoplanets with orbital periods ranging from a few days to several years. The Lick survey identified the first planet in an eccentric orbit (70 Virginis) and the first multi-planet system around a normal main sequence star (Upsilon Andromedae). These discoveries advanced our understanding of planet formation and orbital migration. Data from this project helped to quantify a correlation between host star metallicity and the occurrence rate of gas giant planets. The program also served as a test bed for innovation with testing of a tip-tilt system at the coud{\\'e} focus and fiber scrambler designs to stabilize illumination of the spectrometer optics. The Lick planet search with the Hamilton spectrograph effectively ended when a heat...

    We report on 25 subarcsecond binaries, detected for the first time by means of lunar occultations in the near-infrared (near-IR) as part of a long-term program using the ISAAC instrument at the ESO Very Large Telescope. The primaries have magnitudes in the range K = 3.8-10.4, and the companions in the range K = 6.4-12.1. The magnitude differences have a median value of 2.8, with the largest being 5.4. The projected separations are in the range 6-748 mas and with a median of 18 mas, or about three times less than the diffraction limit of the telescope. Among our binary detections are a pre-main-sequence star and an enigmatic Mira-like variable previously suspected to have a companion. Additionally, we quote an accurate first-time near-IR detection of a previously known wider binary. We discuss our findings on an individual basis as far as made possible by the available literature, and we examine them from a statistical point of view. We derive a typical frequency of binarity among field stars of Almost-Equal-To 10%, in the resolution and sensitivity range afforded by the technique ( Almost-Equal-To 0.''003 to Almost-Equal-To 0.''5, and K Almost-Equal-To 12 mag, respectively). This is in line with previous results using the same technique but we point out interesting differences that we can trace up to sensitivity, time sampling, and average distance of the targets. Finally, we discuss the prospects for further follow-up studies.

    2008-01-01

    Over the last 25 years in the Netherlands the residency training programme for psychiatry has been concerned primarily with teaching students to use practice guidelines, providing science education, promoting internationalisation and satisfying society's requirement for transparency. This has led to the transformation of the classical training programme with its paternalistic 'master-apprentice' relationship to a programme in which the required professional competencies are taught and assessed by supervisors who in the future will need to be explicitly qualified in particular areas. The dramatic increase in the number of women wanting to become psychiatrists has made it clear that the classical training programme puts a heavy burden on students who are struggling to combine private life with a heavy work-load and enthusiasm for their chosen subject. The compulsory personal therapy in the curriculum may be helpful in solving this problem.

    Employee commitment is one of the most important principles of practice man- agement. Yet commitment is delicate; it must be carefully earned, and it can easily deteriorate. This article explores practical strategies the medical practice manager can use to assess, foster, and increase employee commitment. It de- fines commitment and how commitment is manifested in employee attitudes and behavior. It provides a 10-question guide medical practice managers can use to assess employee commitment, and a four-part roadmap that will inspire commitment through leadership. This article also offers 25 hands-on strate- gies to increase employee commitment, and more than a dozen questions to guide difficult conversations with employees when their commitment level to the medical practice is low or unclear. Finally, this article suggest four drivers of employee commitment and a five-part strategy medical practice managers can use to model commitment through their own leadership.

    2011-02-01

    In this essay, we take the publication of the seventh edition of the casebook Social Science in Law (2010) as an opportunity to reflect on continuities and changes that have occurred in the application of social science research to American law over the past quarter-century. We structure these reflections by comparing and contrasting the original edition of the book with the current one. When the first edition appeared, courts' reliance on social science was often confused and always contested. Now, courts' reliance on social science is so common as to be unremarkable. What has changed--sometimes radically--are the substantive legal questions on which social science has been brought to bear.

    The antioxidant activity of the crude n-hexane, dichloromethane, and methanol extracts from 25 species belonging to the Asteraceae, Euphorbiaceae, Rubiaceae, and Solanaceae families collected at natural reserves from the Eje Cafetero Ecorregión Colombia, were evaluated by using the spectrophotometric 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical-scavenging method. The strongest antioxidant activities were showed by the methanol and dichloromethane extracts from the Euphorbiaceae, Alchornea coelophylla (IC50 41.14 mg/l) and Acalypha platyphilla (IC50 111.99 mg/l), respectively. These two species had stronger DPPH radical scavenging activities than hydroquinone (IC50 151.19 mg/l), the positive control. The potential use of Colombian flora for their antioxidant activities is discussed.

    Cervical spondylolysis, with or without spondylolisthesis, is a rare condition defined as a corticated cleft between the superior and inferior articular facets of the articular pillar. The defect occurs predominantly at C6, and is usually bilateral in up to two-thirds of cases. Multilevel involvement is uncommon, however, to date, no case of two consecutive levels of unilateral cervical spondylolysis on opposite sides has been reported. Here, we report a rare case of a patient affected by two consecutive levels of unilateral cervical spondylolysis at C5 and C6 on opposite sides in a 19-year-old male complaining of neck pain.

    We report on the discovery of consecutive bright radio pulses from the Vela pulsar, a new phenomenon that may lead to a greater understanding of the pulsar emission mechanism. This results from a total of 345 hr worth of observations of the Vela pulsar using the University of Tasmania's 26 m radio telescope to study the frequency and statistics of abnormally bright pulses and sub-pulses. The bright pulses show a tendency to appear consecutively. The observations found two groups of six consecutive bright pulses and many groups of two to five bright pulses in a row. The strong radio emission process that produces the six bright pulses lasts between 0.4 and 0.6 s. The numbers of bright pulses in sequence far exceed what would be expected if individual bright pulses were independent random events. Consecutive bright pulses must be generated by an emission process that is long lived relative to the rotation period of the neutron star.

    Seventy-five consecutive patients undergoing hysterectomy subsequent to elective sterilization were studied regarding the occurrence of the post-tubal-ligation syndrome of pelvic pain and/or menorrhagia. Twenty patients were clinically considered to have the syndrome. In none of the patients operated on specifically for menstrual abnormalities could the findings be remotely attributed to the sterilization procedure. Five of the 20 patients had pelvic varicosities and one had pelvic adhesions that may have been a consequence of previous sterilization and conceivably the cause for the pelvic pain for which the patients were undergoing hysterectomy. I question the legitimacy of the post-tubal-ligation syndrome as a reason for hysterectomy.

    To test the predictive value of stairs climbing test for the development of postoperative complications in lung cancer patients with forced expiratory volume in one second (FEV1)stairs climbing with pulse oximetry before the operation with the number of steps climbed and the time to complete the test recorded. Oxygen saturation and pulse rate were measured every 20 steps. Data on postoperative complications including oxygen use, prolonged mechanical ventilation, and early postoperative mortality were collected. Eighty-seven of 101 patients (86%) had at least one postoperative complication. The type of surgery was significantly associated with postoperative complications (25.5% patients with lobectomy had no early postoperative complications), while age, gender, smoking status, postoperative oxygenation, and artificial ventilation were not. There were more postoperative complications in more extensive and serious types of surgery (Pstairs climbing test produced a significant decrease in oxygen saturation (-1%) and increase in pulse rate (by 10/min) for every 20 steps climbed. The stairs climbing test was predictive for postoperative complications only in lobectomy group, with the best predictive parameter being the quotient of oxygen saturation after 40 steps and test duration (positive likelihood ratio [LR], 2.4; 95% confidence interval [CI], 1.71-3.38; negative LR, 0.53; 95% CI, 0.38-0.76). In patients with other types of surgery the only significant predictive parameter for incident severe postoperative complications was the number of days on artificial ventilation (P=0.006). Stairs climbing test should be done in routine clinical practice as a standard test for risk assessment and prediction of the development of postoperative complications in lung cancer patients selected for elective surgery (lobectomy). Comparative to spirometry, it detects serious disorders in oxygen transport that are a baseline for a later development of cardiopulmonary postoperative

    Abstract Radiographic features of consecutive lumbar spondylolisthesis were retrospectively analyzed in a total of 17 patients treated for this condition at the Third Hospital of Hebei Medical University from June 2005 to March 2012. To investigate the radiographic features, pelvic compensatory mechanisms, and possible underlying etiologies of consecutive lumbar spondylolisthesis. To the best of our knowledge, there is no previous report concerning the characteristics of consecutive lumbar spondylolisthesis. The Taillard index and the lumbar lordosis (LL), pelvic incidence (PI), sacrum slope (SS), and pelvic tilt (PT) were determined on lateral X-ray images, and the angular displacement was analyzed on flexion–extension X-ray images. Correlation between LL and various pelvic parameters and correlation between Taillard index and angular displacement were assessed by Pearson correlation analysis. A total of 20 cases of isthmic spondylolisthesis and 14 of degenerative spondylolisthesis were retrospectively studied in 17 patients. The Taillard index and the angular displacement in the lower vertebrae were both larger than those in the upper vertebrae. Statistical analysis revealed that LL was correlated with PI and PT, whereas PI was correlated with PT and SS. However, no correlation was identified between Taillard index and angular displacement. In consecutive lumbar spondylolisthesis, the degree of vertebral slip and the angular displacement of the lower vertebrae were both greater than those of the upper vertebrae, indicating that the compensatory mechanism of the pelvis plays an important role in maintaining sagittal balance.

    A retrospective analysis of 88 consecutive pediatric patients who underwent surgical correction of their dentofacial deformities is presented. There were twice as many female as male patients and the most common deformities were of the skeletal Class II type. The LeFort I osteotomy was the most frequently performed operation. The effect of controlled hypotensive anesthesia on the duration of both anesthesia and surgery, estimated blood loss and incidence of transfusion is discussed. Surgery for the correction of dentofacial deformities can be performed on children and adolescent patients with little morbidity and few complications.

Idade e complicações intra-operatórias foram identificadas como fatores de risco para a conversão. A presença de lesões associadas foi significativamente correlacionada com a persistência de sintomas funcionais do cólon durante o seguimento. CONCLUSÕES: A colectomia laparoscópica esquerda é segura e eficaz em comparação com todas as outras modalidades de tratamento da doença diverticular. Diagnóstico preciso e cuidado nas indicações são essenciais para atingir bons resultados.BACKGROUND: The increased prevalence of diverticular disease has made its most appropriate management a matter of constant debate. Especially for the cases of diverticulitis, considerable progress has been made in terms of diagnosis and management. The surgical resection of the involved colon is the only means of definitely eradicate this condition and so, the elective laparoscopic colectomy has emerged as a safe and interesting choice among the options of treatment. AIM: To analyze the outcomes of the laparoscopic left colectomy for diverticular disease performed over a 17-year period at a single institution. METHODS: Between April 1990 and May 2007, a total of 205 consecutive left laparoscopic colectomies were retrospectively reviewed. Data obtained included the pre-operative work-up, indications for surgery, operative results, complications and follow-up. Univariate and multivariate statistical analyzes were performed in an effort to identity risk factors for adverse outcomes in the series. RESULTS: Indications were for non-complicated acute diverticulitis (80%, acute or chronic complicated diverticulitis (18.05% and bleeding diverticular disease (1.95%. The conversion rate was 5.85% (12 cases. The median operative time was 180 (100-420 min with a hospital stay of 7 (5-44 days. The mean length of the

    We present a ?rst study on the energy required to reduce a unit mass fragment by consecutively using several devices, as it happens in the mining industry. Two devices are considered, which we represent as different stochastic fragmentation processes. Following the self-similar energy model introduced by Bertoin and Martinez, we compute the average energy required to attain a size x with this two-device procedure. We then asymptotically compare, as x goes to 0 or 1, its energy requirement with that of individual fragmentation processes. In particular, we show that for certain range of parameters of the fragmentation processes and of their energy cost-functions, the consecutive use of two devices can be asymptotically more efficient than using each of them separately, or conversely.

    The following report describes two consecutive brothers from a nonimmigrant family, with no identifiable predisposing factors, who presented with osteosarcomas of their distal femurs, one at the age of 18 years and the other at the age of 21 years. Until a cost-effective program is developed to screen for osteosarcoma, a detailed family history should be obtained from every new patient with osteosarcoma and parents should be urged to schedule early evaluations of siblings with complaints of painful extremities. Increased frequency of cytogenetic studies to screen for genetic abnormalities in patients with osteosarcoma is recommended to help elucidate the cause of osteosarcoma.

    The first aim of this study was to evaluate combination antiemetic therapy consisting of 5-HT3 receptor antagonists, neurokinin-1 receptor antagonists (NK-1RAs), and dexamethasone for multiple high emetogenic risk (HER) anticancer agents in bone and soft tissue sarcoma. The second aim was to compare the effectiveness of single-shot palonosetron and consecutive-day granisetron in a randomized, single-blinded crossover study. A single randomization method was used to assign eligible patients to the palonosetron or granisetron arm. Patients in the palonosetron arm received a palonosetron regimen during the first and third chemotherapy courses and a granisetron regimen during the second and fourth courses. All patients received NK-1RA and dexamethasone. Patients receiving the palonosetron regimen were administered 0.75 mg palonosetron on day 1, and patients receiving the granisetron regimen were administered 3 mg granisetron twice daily on days 1 through 5. All 24 patients in this study received at least 4 chemotherapy courses. A total of 96 courses of antiemetic therapy were evaluated. Overall, the complete response CR rate (no emetic episodes and no rescue medication use) was 34%, while the total control rate (a CR plus no nausea) was 7%. No significant differences were observed between single-shot palonosetron and consecutive-day granisetron. Antiemetic therapy with a 3-drug combination was not sufficient to control chemotherapy-induced nausea and vomiting (CINV) during chemotherapy with multiple HER agents for bone and soft tissue sarcoma. This study also demonstrated that consecutive-day granisetron was not inferior to single-shot palonosetron for treating CINV.

    Full Text Available Statement of Problem. Low scientific evidence is identified in the literature for combining implant placement in fresh extraction sockets with immediate function. Moreover, the few studies available on immediate implants in postextraction sites supporting immediate full-arch rehabilitation clearly lack comprehensive protocols. Purpose. The purpose of this study is to report outcomes of a comprehensive protocol using CAD-CAM technology for surgical planning and fabrication of a surgical template and to demonstrate that immediate function can be easily performed with immediate implants in postextraction sites supporting full-arch rehabilitation. Material and Methods. 14 subjects were consecutively rehabilitated (13 maxillae and 1 mandible with 99 implants supporting full-arch fixed prostheses followed between 6 and 24 months (mean of 16 months. Outcome measures were prosthesis and implant success, biologic and prosthetic complications, pain, oedema evaluation, and radiographic marginal bone levels at surgery and then at 6, 12, 18, and 24 months. Data were analyzed with descriptive statistics. Results. The overall cumulative implant survival rate at mean follow-up time of 16 months was 97.97%. The average marginal bone loss was 0,9 mm. Conclusions. Within the limitations of this study, the results validate this treatment modality for full-arch rehabilitations with predictable outcomes and high survival rate after 2 years.

    Full Text Available Purpose: To evaluate the efficiency of medial rectus advancement surgery in consecutive exotropia. Material and Methods: The study group consisted of 20 cases, 10 male, 10 female, who were diagnosed as consecutive exotropia and underwent surgery between 2008-2013 at Cukurova University Medical Faculty Ophthalmology Department. Records of the patients were investigated retrospectively. We evaluated best corrected visual acuity, existence of ambliopia, postoperative duration following the first surgery and applied surgical procedures. Postoperative deviation lower than 10 PD were assesed as successful. Mean follow up period was 29,8 +/- 21,36 (8-80 months, patients with inadequate follow up period were dismissed from the study group. Results: We only applied bilateral medial rectus advancement surgery to 6 and unilateral medial rectus advancement surgery to 5 patients and obtained intended surgical result in these 11 cases. The other patients underwent lateral rectus recession or/and medial rectus resection operations inorder to reach projected deviation degrees. Deviation was found to be 46,4+/-9,24 (40-70 PD in cases who only underwent advancement surgery and was 65,56 +/- 18,78 (40-90 PD in cases who underwent additional surgical procedure. 16 (%80 of the cases had hypermetropi various dioptries and 7 (%35 had ambliopia. Discussion: Consecutive exotropia can appear years after surgery and is an important late period complication. In this study achievement of %55 success with medial rectus advancement surgery indicates that this is a preferable procedure. But in wide angle deviations additional lateral rectus recession or/and medial rectus resection operations can be applied inorder to reach intended adjustment. Accurrate prediction of the propotion of advancement surgery and adjustment is not always possible because of intensive fybrosis in operated muscles and enviroment tissue.

    We describe a substitution based sparse Jacobian matrix determination method using algorithmic differentiation. Utilizing the a priori known sparsity pattern, a compression scheme is determined using graph coloring. The "compressed pattern" of the Jacobian matrix is then reordered into a form suitable for computation by substitution. We show that the column reordering of the compressed pattern matrix (so as to align the zero entries into consecutive locations in each row) can be viewed as a variant of traveling salesman problem. Preliminary computational results show that on the test problems the performance of nearest-neighbor type heuristic algorithms is highly encouraging.

    Aggressive non-Hodgkin's lymphomas (NHL) in patients under the age of 60 have a very poor prognosis when the international prognostic index (IPI) is high, with an age-adjusted (Aa)-IPI score at 3. In such patients, conventional chemotherapy results in a low complete response (CR) rate of 46%, a five-year survival and disease-free survival (DFS) of 32% and 58%, respectively. For this report we have analyzed whether front-line high-dose chemotherapy could influence the outcome of this group of patients. From 1992 onwards we conducted two pilot clinical trials of intensive sequential chemotherapy (ISC) with growth factors and blood stem cell support as initial treatment in 62 poor-risk patients with aggressive NHL. Of these patients, 33 were considered to be a high-risk group based on the Aa-IPI. The median age was 42 years (range 21-60). The treatment was completed in 88% of patients, 86% receiving greater than 75% or more of the projected dose-intensity. Twenty patients (61%) achieved a CR. At a median follow-up of 48 months (range 26-86), the estimated five-year survival and DFS was 51% (95% confidence interval (CI): 34%-68%) and 70% (95% CI: 50%-90%), respectively. These results suggest that primary treatment using high-dose therapy supported by both growth factors and peripheral blood stem cells can cure up to 50% of high-risk patients with malignant lymphomas.

    Cohort studies of large series of patients with sarcoidosis over a long period of time are scarce. The aim of this study is to report a 40-year clinical experience of a large series of patients at Bellvitge University Hospital, a tertiary university hospital in Barcelona, Spain. Diagnosis of sarcoidosis required histological confirmation except in certain specific situations. All patients underwent a prospective study protocol. Clinical assessment and follow-up of patients were performed by a multidisciplinary team.From 1976 to 2015, 640 patients were diagnosed with sarcoidosis, 438 of them (68.4%) were female (sex ratio F/M 2:1). The mean age at diagnosis was 43.3 ± 13.8 years (range, 14-86 years), and 613 patients (95.8%) were Caucasian. At diagnosis, 584 patients (91.2%) showed intrathoracic involvement at chest radiograph, and most of the patients had normal pulmonary function. Erythema nodosum (39.8%) and specific cutaneous lesions (20.8%) were the most frequent extrapulmonary manifestations, but there was a wide range of organ involvement. A total of 492 patients (76.8%) had positive histology. Follow-up was carried out in 587 patients (91.7%), over a mean of 112.4 ± 98.3 months (range, 6.4-475 months). Corticosteroid treatment was administered in 255 patients (43.4%), and steroid-sparing agents in 49 patients (7.7%). Outcomes were as follows: 111 patients (18.9%) showed active disease at the time of closing this study, 250 (42.6%) presented spontaneous remission, 61 (10.4%) had remission under treatment, and 165 (28.1%) evolved to chronic sarcoidosis; among them, 115 (19.6%) with mild disease and 50 (8.5%) with moderate to severe organ damage. A multivariate analysis showed that at diagnosis, age more than 40 years, the presence of pulmonary involvement on chest radiograph, splenic involvement, and the need of treatment, was associated with chronic sarcoidosis, whereas Löfgren syndrome and mediastinal lymphadenopathy on chest radiograph were

    Real-life safety and efficacy of sorafenib in advanced renal cell carcinoma in a nationwide patient population were evaluated by post-marketing all-patient surveillance. All patients with unresectable or metastatic renal cell carcinoma in Japan who started sorafenib therapy from February 2008 to September 2009 were registered and followed for up to 12 months. Baseline characteristics, treatment status, tumor response, survival and safety data were recorded by the prescribing physicians. Safety and efficacy were evaluated in 3255 and 3171 patients, respectively. The initial daily dose was 800 mg in 78.2% of patients. Median duration of treatment was 6.7 months and the mean relative dose intensity was 68.4%. Overall, 2227 patients (68.4%) discontinued the treatment by 12 months, half of which (52.0% of discontinued patients) were due to adverse events. The most common adverse drug reactions were hand-foot skin reaction (59%), hypertension (36%), rash (25%) and increase in lipase/amylase (23%). The median progression-free survival was 7.3 months (95% confidence intervals: 6.7-8.1), and the overall survival rate at 1 year was 75.4% (73.5-77.1). Prognostic factors for overall survival were mostly consistent with those in previous clinical trials in the univariate analysis and largely similar to those for progression-free survival and duration of treatment in the multivariate analysis. Sorafenib for the treatment of advanced renal cell carcinoma under the labeled dose was feasible in daily medical practice, for its acceptable toxicity profile and favorable clinical benefit that were consistent with those in clinical trials. © The Author 2015.

    The imaging and surgical literature has confusing association rates for the association between sporadic intracranial cavernous malformations (CMs) and developmental venous anomalies (DVAs). In this study, our purpose was to determine the association rate using ultra-high-resolution C-arm flat-detector CT angiography (FDCTA) and compare it with literature. Fifty-eight patients with 60 sporadic intracranial CMs that underwent an FDCTA study were included in our retrospective study. Re-evaluation of radiological data was performed based on the criteria defined by authors. Isotropic volumetric reconstructions with ultra-high resolution (voxel size of 102 μm{sup 3} for initial; 67 μm{sup 3} and 32 μm{sup 3} for further evaluation) were used for assessment. Sixteen patients underwent surgery for excision of their CMs. Fifty-one of all patients (87.9 %) were associated with a DVA. Undefined local venous structures (UD-LVSs) were observed in the remaining 7 patients (12.1 %). The strength of interobserver agreement was excellent [kappa(k) coefficient = 0.923]. Ultra-high-resolution FDCTA evaluation of CMs and DVAs reveals 3-fold higher association rate compared to the literature. FDCTA for patients with sporadic CMs could help identify the associated DVAs that remained undetected or unclear with other imaging modalities, which can be useful in decision-making processes, planning surgery, and during operation.

    AIM:To evaluate the incidence of contrast-induced nephropathy (CIN) in cirrhotic patients and to identify risk factors for the development of CIN. METHODS:We performed a retrospective review of 216 consecutive patients with cirrhosis who underwent computed tomography (CT) with intravenous contrast at the University of Rochester between the years 2000-2005. We retrospectively examined factors associated with a high risk for CIN, defined as a decrease in creatinine clearance of 25% or greater within one week after receiving contrast. RESULTS:Twenty-five percent of our patients developed CIN, and 74% of these patients had ascites seen on CT. Of the 75% of patients who did not develop CIN, only 46% had ascites. The presence of ascites was a significant risk factor for the development of CIN ( P = 0.0009, OR 3.38, 95% CI 1.55-7.34) in multivariate analysis. Patient age, serum sodium, Model for End-stage Liver Disease score, diuretic use, and the presence of diabetes were not found to be significant risk factors for the development of CIN. Of the patients who developed CIN, 11% developed chronic renal insufficiency, defined as a creatinine clearance less than baseline for 6 wk. CONCLUSION:Our results suggest that in hospitalized cirrhotic patients, especially those with ascites, the risk of CIN is substantial.

    Fifty consecutive matched patients with benign or malignant biliary tract obstruction were compared to determine the efficacy of preoperative percutaneous biliary drainage (PBD). Twenty-five patients underwent PBD for an average of nine days before operation; 25 patients underwent percutaneous transhepatic cholangiography ( PTHC ) followed immediately by operation. Serum bilirubin levels before PTHC were 16.5 +/- 7.6 mg/dL and 14.9 +/- 7.6 mg/dL in PBD and non-PBD groups, respectively. Serum bilirubin levels decreased to 6.5 +/- 6.2 mg/dL preoperatively in patients having PBD. One week after operation, bilirubin levels were 4.2 +/- 4.3 mg/dL and 9.0 +/- 5.2 mg/dL in the PBD and non-PBD groups, respectively. Major morbidity (sepsis, abscess, renal failure, or bleeding) occurred in two patients (8%) having PBD and in 13 patients (52%) without PBD. One patient (4%) with PBD, and five patients (20%) without PBD, died. The mean hospital stay was shorter for the PBD group. Preoperative PBD reduces operative mortality and morbidity and results in a more rapid resolution of hyperbilirubinemia during the postoperative period.

    OBJECTIVES The European System for Cardiac Operative Risk Evaluation (EuroSCORE) II was developed to improve the overestimation of surgical risk associated with the original (additive and logistic) EuroSCOREs. The purpose of this study was to evaluate the significance of the EuroSCORE II by comparing its performance with that of the original EuroSCOREs in Japanese patients undergoing surgery on the thoracic aorta. METHODS We have calculated the predicted mortalities according to the additive EuroSCORE, logistic EuroSCORE and EuroSCORE II algorithms in 461 patients who underwent surgery on the thoracic aorta during a period of 20 years (1993–2013). RESULTS The actual in-hospital mortality rates in the low- (additive EuroSCORE of 3–6), moderate- (7–11) and high-risk (≥11) groups (followed by overall mortality) were 1.3, 6.2 and 14.4% (7.2% overall), respectively. Among the three different risk groups, the expected mortality rates were 5.5 ± 0.6, 9.1 ± 0.7 and 13.5 ± 0.2% (9.5 ± 0.1% overall) by the additive EuroSCORE algorithm, 5.3 ± 0.1, 16 ± 0.4 and 42.4 ± 1.3% (19.9 ± 0.7% overall) by the logistic EuroSCORE algorithm and 1.6 ± 0.1, 5.2 ± 0.2 and 18.5 ± 1.3% (7.4 ± 0.4% overall) by the EuroSCORE II algorithm, indicating poor prediction (P < 0.0001) of the mortality in the high-risk group, especially by the logistic EuroSCORE. The areas under the receiver operating characteristic curves of the additive EuroSCORE, logistic EuroSCORE and EuroSCORE II algorithms were 0.6937, 0.7169 and 0.7697, respectively. Thus, the mortality expected by the EuroSCORE II more closely matched the actual mortality in all three risk groups. In contrast, the mortality expected by the logistic EuroSCORE overestimated the risks in the moderate- (P = 0.0002) and high-risk (P < 0.0001) patient groups. CONCLUSIONS Although all of the original EuroSCOREs and EuroSCORE II appreciably predicted the surgical mortality for thoracic aortic surgery in Japanese patients, the Euro

    The study aimed at determining the different types of precancerous conditions of the stomach and searches the frequency of Helicobacter pylori in these lesions in patients with chronic antral gastritis in Yaounde, Cameroon. Five gastric biopsies were performed during upper gastrointestinal endoscopy for pathology and fixed in formol 10% before being coated in paraffin. Both the modified Giemsa and Periodic acid of Shift - Alkaline blue stains were used for the histological diagnosis of Helicobacter pylori infection. Hematoxylyn and eosin stain was used to determine the activity of gastritis, atrophic gastritis and intestinal metaplasia in accordance to the Sydney's classification of gastritis. Data were analysed using both the Epi info 6.04 and Excel 2007 softwares. Means and their standard deviations, medians and their interquartiles (IQR) were calculated. Proportions were established for qualitative variables and chi square analysis done in this study with a p value set at 0.05. Seventy-nine patients with chronic antral gastritis were enrolled, of which 43 (54.4%) were male, median age: 43 years (range from 21 to 70 years). The rate of atrophic gastritis was 74.7% (59/79). The activity of atrophic gastritis was mild in 47.5% (28/59) of cases, moderate in 47.5% (28/59) and severe in 5% (5/59). Intestinal metaplasia and follicular gastritis were present in 6.3% (5/79), and 10.1% (8/79), respectively. Concerning Helicobacter pylori infection, 71.2% (42/59) of patients with atrophic gastritis tested positive against 28.8% (17/59) who tested negative (p=0.00003). Helicobacter pylori infection was related to the severity of gastric atrophy (p=0.0001). Among patients with intestinal metaplasia and follicular gastritis, the proportion of those who tested positive for Helicobacter pylori infection was 80% (4/5), and 75% (6/8), respectively. There were no significant differences in the occurrence of atrophic gastritis according to age groups (p=0.908). This study concludes

    To describe clinical and laboratory features of human immunodeficiency infection (HIV)-infected patients with neurosyphilis. Retrospective study of 27 consecutive cases of HIV-infected patients with a positive Venereal Disease Research Laboratory (VDRL) in cerebrospinal fluid (CSF). Median of age was 36 years and 89% were men. Ten (37%) patients had previous nonneurologic syphilis treatment. At the time of neurosyphilis diagnosis, 10 (37%) patients had early syphilis, and 6 of them were neurologically asymptomatic. Nine (33%) patients had symptomatic neurosyphilis. Twenty-six (96%) patients were classified with early neurosyphilis. The medians of serum VDRL and CD4 T cell counts were 1:128 and 182 cell/muL, respectively. Twenty five (93%) patients presented serum VDRL titers > or =1:16. Five of 6 patients with early syphilis and asymptomatic neurosyphilis, presented serum VDRL > or =1:16. Symptomatic patients showed lower CD4 T cell counts (59 cell/muL vs. 208 cell/muL, P = 0.03) and higher protein concentration on CSF (118 mg/dL vs. 39 mg/dL, P VDRL titers > or =1:16, regardless of syphilis stage.

    Full Text Available Psoriasis is a disease characterized by increased epidermal cell turnover and hence an increase in purine catabolism. The serum uric acid levels in psoriasis are expected to be raised because of the high purine catabolism. AIM To study the levels of serum uric acid in 25 cases of uncomplicated chronic plaque type psoriasis. MATERIALS AND METHODS Twenty five consecutive patients with chronic plaque type psoriasis attending the Dermatology OPD of a Tertiary Care Hospital were selected and their serum uric acid levels were estimated. RESULTS The average uric acid levels in males psoriatic patients was between 3.6-7.7mg/dl and in the female psoriasis patients, the serum uric acid values were between 2.5-6.8mg/dl. DISCUSSION The serum levels of uric acid in uncomplicated chronic plaque type psoriasis were within the normal ranges for both male and female patients. Since only chronic plaque type psoriasis patients were included in the study and the severity of disease is less in such patients when compared to erythrodermic or unstable psoriasis, the serum uric levels were observed to be within the normal ranges. CONCLUSION This study concludes that the serum uric acid levels are not raised in chronic plaque type psoriasis, patients with less disease severity.

    Aneurysms of the ascending aorta, if undiagnosed or untreated, may result in left ventricular failure from aortic valvular insufficiency. Aortic rupture, dissection, or compression of adjacent vital structures may also occur. The application of refined cardiopulmonary bypass devices, prosthetic heart valves, and synthetic grafts now allows successful surgical management of this disorder. This report presents our current diagnostic methods, surgical techniques, and the early and late results of 100 consecutive patients undergoing surgical treatment of aneurysms of the ascending aorta. There were 72 males and 28 females, ranging in age from 25 to 72 (ave 51.2) years. All patients had angiographic studies to demonstrate precisely the location of the aneurysm and the presence or absence of aortic valvular insufficiency. Sixty-three patients required concomitant aortic valve replacement, and the remaining 37 patients had only aneurysm resection and replacement. Pathological studies revealed 69 aneurysms were atherosclerotic, 22 were secondary to cystic medial necrosis, with the remaining 9 considered to be possibly leutic in origin. Despite the magnitude of the surgery and the advanced ages of some of these patients, the overall operative and hospital mortality rates were 4% and 9%. Survival rates by actuarial representation in 82 patients at 2, 4, 6, and 8 years were 82.9%, 78%, 70%, and 69.5%, respectively.

    Epigastric herniation is a common, though not always symptomatic condition. It is likely, that in accordance to the tension-free principles for other hernias, epigastric hernia repair should be mesh based. Patients from two large hospitals were investigated retrospectively if they were operated on an epigastric hernia for the past 6 years. Follow-up was completed with a postal questionnaire. A total of 235 patients (50 % male) were operated. Sixty-eight patients were operated with mesh and 167 patients with suture repair. Forty-six patients were loss-to follow-up (19.6 %). In the mesh operated patients the recurrence rate was 10.9 % (n = 6) compared to 14.9 % (n = 20) in the suture repair group. Cox-regression analysis showed an increased risk for recurrence in the suture repair group (odds ratio 1.43; 95 % CI 0.56-3.57; p = 0.44). Operation time for mesh repair (47 min) was significantly longer compared to suture repair (29 min) (p hernias. A total of 51 patients smoked and 14 patients had diabetes mellitus. Fourteen patients used steroids and 22 patients suffered from a chronic lung disease. Subgroup analysis showed a significant difference for pain in patients in which re-operation for a recurrence occurred (p = 0.004). This is one of the largest reported series on solely epigastric hernias. A recurrence occurred more often after sutured repair compared to mesh repair. No differences in chronic pain was seen between mesh and suture repaired patients. Male:female ratio of 1:1, which is different from the 3:1 ratio found in previous older smaller studies, could be more reliable.

    Background Although liver transplantation has become a standard therapy for end-stage liver diseases, the experience of pediatric liver transplantation is limited in China. In this article we report our experience in pediatric liver transplantation, and summarize its characters in their indications, surgical techniques, and postoperative managements. Methods Thirty-one children (≤18 years old) underwent liver transplantation in our centers. The mean age at transplantation was 12.4 years old (ranged from 5 months to 18 years) with 7 children being less than 4 years of age at transplantation. The most common diagnosis of patients who underwent liver transplantation were biliary atresia, Wilson's disease, primary biliary cirrhosis, glycogen storage disease, hepatoblastoma, urea cycle defects, fulminant hepatic failure, etc. The surgical procedures included 12 standard (without venovenous bypass), 6 pigyback, 6 reduced-size, 3 split, 3 living donor liver transplantation, and 1 Domino liver transplantation. The triple-drug (FK506, steroid, and mycophenolate mofetil) immunosuppressive regimen was used in most of patients. Patients were followed up for a mean of 21.8 months. Results Five of the 31 patients died during perioperative time; mortality rate was 16.1%. The reasons of death were infections, primary non-function, heart failure, and hypovolemic shock. Postoperative complications in 10 patients included biliary leakage, acute rejection, abdominal infection, hepatitis B virus (HBV) or hepatitis C virus (HCV) infection, and pulmonary infection. Overall patient cumulative survival rate at 1-, 3-, and 5-year was 78.1%, 62.6%, 62.6%, respectively.Conclusions The most common indications of pediatric liver transplantation were congenital end-stage liver diseases. According to patients' age and body weight, standard, piggyback, reduced-size, split, or living donor liver transplantation should be performed. Pediatric liver transplantation especially requires higher

    The clinical records and histologic material of 18 consecutive patients with malignant histiocytosis were reviewed. The age of the patients ranged from 20 months to 72 years (median 35 years). There were 14 males and 4 females (3.5:1). Lymph node and liver enlargement, fever, and skin nodules were the most common physical findings; and leukocytosis was frequently the most abnormal laboratory test. Seven of 18 patients died, and their survival ranged from 1 to 15 months (median 8 months) after histopathologic diagnosis. The histologic findings on lymph nodes, spleen, liver, bone marrow, and skin were investigated with special reference to both the cellular composition and the pattern of lymph node involvement. Vascular invasion of small perinodal vessels was observed in 4 fatal cases. The absence of capsular invasion and the lack of cohesiveness among atypical proliferating histiocytes of malignant histiocytosis appeared to be inconstant. Sequential lymph node biopsies revealed in later stages the extension of the histiocytic proliferation from the sinuses into the cords and the complete obliteration of the nodal structures. The radiologic investigations yielded numerous pathologic findings that were consistent with the dissemination of the disease. Complete response to initial treatment was achieved in patients that were treated with radiotherapy and/or chemotherapy. Complete response with chemotherapy was achieved only when the treatment included adriamycin. The histologic and clinical features of the present series provide future evidence for the recognition of malignant histiocytosis as a distinct clinical and pathologic entity.

    Full Text Available Abstract Background Fever is an undifferentiated clinical feature that may enhance the sensitivity of syndromic surveillance systems. By studying the spatiotemporal associations of febrile patients, it may allow early detection of case clustering that indicates imminent threat of infectious disease outbreaks in the community. Methods We captured consecutive emergency department visits that led to hospitalization in a district hospital in Hong Kong during the period of 12 Sep 2005 to 14 Oct 2005. We recorded demographic data, provisional diagnoses, temperature on presentation and residential location for each patient-episode, and geocoded the residential addresses. We applied Geographical Information System technology to study the geographical distribution these cases, and their associations within a 50-m buffer zone spatially. A case cluster was defined by three or more spatially associated febrile patients within each three consecutive days. Results One thousand and sixty six patient-episodes were eligible for analysis; 42% of them had fever (>37°C; oral temperature on presentation. Two hundred and four patient-episodes (19.1% came from residential care homes for elderly (RCHE. We detected a total of 40 case clusters during the study period. Clustered cases were of older age; 57 (33.3% were residents of RCHE. We found a median of 3 patients (range: 3 - 8 and time span of 3 days (range: 2 - 8 days in each cluster. Twenty five clusters had 2 or more patients living in the same building block; 18 of them were from RCHE. Conclusions It is technically feasible to perform surveillance on febrile patients and studying their spatiotemporal associations. The information is potentially useful for early detection of impending infectious disease threats.

    The Chao Phraya basin, Thailand, is frequently inundated by flooding during the southwest monsoon period. Most floods coincide with consecutive rainfall days. This study investigated consecutive rainfall days during the southwest monsoon period at 11 stations over northern Thailand, the upstream area of this basin. The Markov chain probability model was used to study the consecutiveness of days with at least 0.1, 10.1, and 35.1 mm of rainfall. The consecutive length of rainfall days from the model showed good agreement with the observed value. A chi-square test of independence was applied to assess the significance of the consecutiveness, and it was found that days with at least 10.1 mm of rainfall tend to be consecutive over the entire area. Moreover, days with at least 35.1 mm of rainfall were found to be consecutive over the joint area where the mountainous region meets the plain area. However, the consecutiveness of days with less than 10.1 mm of rainfall was not obvious. The rainfall amount on days with at least 10.1 mm of rainfall was also calculated and it showed lower values over the mountainous region than over the plain. Hence, this study established the characteristics of consecutive rainfall days over the plain, mountainous region, and joint area.

    AIM To compare a group of patients with consecutive exotropia with patients who had ≤10 prism diopters (PD) esotropia or no deviation postoperatively in terms of probable clinical risk factors for the development of consecutive exotropia. METHODS The study recruited fourteen patients who developed consecutive exodeviation during follow-up period after the correction of esotropia who were categorized as group 1 and thirty-one patients who had still ≤10 PD esotropia or no deviation at the final visit that were considered as group 2. Clinical risk factors leading the development of consecutive deviation were analyzed as the main outcome measures. RESULTS The mean age of patients was 4.57±3.11y in group 1 and 5.10±3.52y in group 2 (P=0.634). There was no significant difference of preoperative near and distant deviations among two groups (P=0.835, 0.928 respectively). The mean amount of medial rectus recession and lateral rectus resection was similar in both groups (P=0.412, 0.648 respectively). Convergence insufficiency and neurological diseases were more frequent in group 1 (P=0.007, 0.045). Accompanying neurological disease was found to be as a significant factor increasing the risk of the development of consecutive exotropia significantly [odds ratios (OR): 5.75 (1.04-31.93)]. CONCLUSION Accompanying neurological disease appears to be a significant clinical risk factor for the development of consecutive exodeviation during postoperative follow-up after the correction of esotropia. However, larger studies are needed in order to interpret the results to the clinical practice and to ascertain other concurrent risk factors. PMID:27366693

    Huntington's disease (HD) is a neurodegenerative disease caused by the expansion of unstable CAG repeats in the HTT gene. There are scarce data about HD in China. Fifty-eight HD patients were consecutively recruited and assessed using the Unified HD Rating Scale (UHDRS) motor section and UHDRS behaviour assessment (UHDRS-b). Genetic analyses were also conducted. Thirty-three women and Twenty -five men were diagnosed with a mean age of 46.1 ± 11.2 years and a mean number of CAG triplet repeats 44.6 ± 4.4. CAG triplet repeat number was negatively correlated with age at onset, and positively correlated with UHDRS-b total score, and its subdomains including depressed mood, low self-esteem, anxiety and irritability. On the other hand, negative correlations were identified between age at onset and UHDRS-b total score, and its subdomains include low self-esteem, anxiety, suicidal thought, irritability and apathy. Disease durations were correlated with UHDRS motor scores and anxiety domain of UHDRS-b. This is the largest series of Chinese HD patients with demographic, clinical and genetic data confirms the demographic features of Chinese HD patients are comparable to those in other ethnic backgrounds. CAG triplet repeat number may also predict the severity of behaviour problems in HD patients besides its predication for age of onset.

    Breast cancer is the most common cancer in women globally, and tumor size measured as the largest diameter of the tumor focus is currently used in tumor-lymph node-metastasis (TNM) staging for prognosis and treatment decisions. The present study utilized the tumor-to-breast volume ratio (TBR) to evaluate the relative tumor size and determined the prognostic impact of TBR on survival in patients with breast cancer. Two thousand twenty-five consecutive breast cancer patients who underwent modified radical mastectomy between January 2002 and December 2008 at Sun Yat-Sen University Cancer Center were enrolled in this retrospective study. Kaplan-Meier analysis was used to assess the prognostic effect of TBR on cancer-specific survival (CSS), and univariate log-rank test and multivariate Cox proportional hazards regression model were performed to identify independent prognostic factors. The optimal cutoff value of TBR was determined to be 1.70 %, and 1473 and 552 patients were categorized to low-TBR and high-TBR groups, respectively. In the whole patient cohort, CSS was significantly shorter in the high-TBR group (110.2 vs 128.5 months, P breast cancer patients (hazard ratio (HR) 1.489, 95 % CI 1.130-1.961, P = 0.005). High TBR was independently associated with poor prognosis in breast cancer patients. This variable may serve as a valuable parameter to predict the outcomes of breast cancer.

    We report the updated results for a previously described cohort of patients who were less than fifty years old at the time of the index Charnley total hip arthroplasty with cement. The original cohort consisted of ninety-three consecutive hips in sixty-nine patients. The patients were followed for a minimum of thirty-five years after surgery or until death. At the latest follow-up evaluation, there were forty-one total hip replacements (44%) in thirty-two living patients. Thirty-four (37%) of the ninety-three total hip replacements in the original cohort had been revised or removed. Twenty acetabular (22%) and seven femoral (8%) components had been revised for aseptic loosening. Since the twenty-five-year follow-up, the average six-minute-walk distance decreased from 395 m to 171 m, and this decrease correlated with increasing comorbidity. This study demonstrates the durability of cemented total hip replacements in a young patient population. Although 63% (fifty-nine) of the ninety-three original hip replacements were functioning at the latest follow-up or at the time of death, a significant decrease in activity level was seen over time (p < 0.001). Of the forty-one original implants in the patients who were alive at the time of the thirty-five-year follow-up, only 46% (nineteen) were retained.

  3. Computational Approaches to Consecutive Pattern Avoidance in Permutations

    CERN Document Server

    Nakamura, Brian

    2011-01-01

    In recent years, there has been increasing interest in consecutive pattern avoidance in permutations. In this paper, we introduce two approaches to counting permutations that avoid a set of prescribed patterns consecutively. These algoritms have been implemented in the accompanying Maple package CAV, which can be downloaded from the author's website. As a byproduct of the first algorithm, we have a theorem giving a sufficient condition for when two pattern sets are strongly (consecutively) Wilf-Equivalent. For the implementation of the second algorithm, we define the cluster tail generating function and show that it always satisfies a certain functional equation. We also explain how the CAV package can be used to approximate asymptotic constants for single pattern avoidance.

    Ovarian stimulation combined with intra-uterine insemination (IUI) is an effective treatment of non-tubal infertility but most women undergo several cycles of treatment to achieve a pregnancy. This prospective study was designed to assess the consistency (or variation) of ovarian responses and the effect of various ovarian stimulation protocols on this consistency in consecutive cycles of ovarian stimulation and IUI in women with non-ovulatory infertility. A total of 86 regularly menstruating ovulating patients each completed three to six cycles of ovarian stimulation and IUI (n = 347 cycles). Ovarian stimulation was achieved by sequential clomiphene citrate/human menopausal gonadotrophin (HMG), HMG-only or combined gonadotrophin-releasing hormone analogue--HMG protocols in 33, 29 and 24 patients respectively, and each patient used the same protocol consistently throughout the study. Standard methods were used to monitor ovarian response and to perform IUI. Using each patient as her own control, repeated measurements analysis of variance revealed consistency of ovarian response in consecutive ovarian stimulation cycles, as shown by the number and mean diameter of maturing pre-ovulatory follicles, peak plasma oestradiol, duration of stimulation and mean HMG requirements. This consistency existed using any of the ovarian stimulation protocols. We conclude that regularly menstruating and ovulating women are likely to have similar ovarian responses in consecutive cycles of ovarian stimulation and IUI if the same ovarian stimulation protocol is used consistently.(ABSTRACT TRUNCATED AT 250 WORDS)

    When monitoring patients over time, clinicians may struggle to distinguish 'real changes' in consecutive blood parameters from so-called natural fluctuations. In practice, they have to do so by relying on their clinical experience and intuition. We developed Labtracker+, a medical app that calculates the probability that an increase or decrease over time in a specific blood parameter is real, given the time between measurements. We presented patient cases to 135 participants to examine whether there is a difference between medical students, residents and experienced clinicians when it comes to interpreting changes between consecutive laboratory results. Participants were asked to interpret if changes in consecutive laboratory values were likely to be 'real' or rather due to natural fluctuations. The answers of the study participants were compared with the calculated probabilities by the app Labtracker+ and the concordance rates were assessed. Medical students (n=92), medical residents from the department of internal medicine (n=19) and internists (n=24) at a Dutch University Medical Centre. Concordance rates between the study participants and the calculated probabilities by the app Labtracker+ were compared. Besides, we tested whether physicians with clinical experience scored better concordance rates with the app Labtracker+ than inexperienced clinicians. Medical residents and internists showed significantly better concordance rates with the calculated probabilities by the app Labtracker+ than medical students, regarding their interpretation of differences between consecutive laboratory results (p=0.009 and p<0.001, respectively). The app Labtracker+ could serve as a clinical decision tool in the interpretation of consecutive laboratory test results and could contribute to rapid recognition of parameter changes by physicians. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2017.

    Hepatectomies have been increasingly recommended and performed in Brazil; they present great differences related to immediate complications. Assessing the immediate postoperative complications in a series of 88 open liver resections. Prospective database of patients subjected to consecutive hepatectomies over nine years. The post-hepatectomy complications were categorized according to the Clavien-Dindo classification; complications presenting grade equal to or greater than 3 were considered major complications. Hepatic resections involving three or more resected liver segments were considered major hepatectomies. Eighty-four patients were subjected to 88 hepatectomies, mostly were minor liver resections (50 cases, 56.8%). Most patients had malignant diseases (63 cases; 71.6%). The mean hospitalization time was 10.9 days (4-43). Overall morbidity and mortality rates were 37.5% and 6.8%, respectively. The two most common immediate general complications were intra-peritoneal collections (12.5%) and pleural effusion (12.5%). Bleeding, biliary fistula and liver failure were identified in 6.8%, 4.5% and 1.1% of the cases, respectively, among the hepatectomy-specific complications. The patients operated in the second half of the series showed better results, which were apparently influenced by the increased surgical expertise, by the modification of the hepatic parenchyma section method and by the increased organ preservation. No Brasil as hepatectomias têm sido cada vez mais indicadas e realizadas, apresentando grandes diferenças relacionadas às complicações imediatas.

    2014-01-01

    A common misconception is that the phrase workplace diversity means meeting certain quotas in employee race or gender categories. In fact, diversity is much more than that. This article explores the unique benefits and challenges of managing a culturally diverse medical practice team and offers practice managers 25 practical strategies. It describes the two types of diversity training that are beneficial to practice managers and the kinds of policies, practices, and procedures that foster and promote diversity. This article also explores ethnocentrism, racism, ageism, sexism, stereotyping, and other potentially divisive issues among a diverse medical practice team. It provides an assessment instrument practice managers can use to evaluate their own diversity management skills. Finally, this article defines specifically what is meant by the term diversity and explores the top 10 diversity issues in workplaces today.

    2008-02-15

    In this historical review covering the past 25 years, we reflect on the content of manuscripts relevant to the Sport Performance section of the Journal of Sports Sciences. Due to the wide diversity of sport performance research, the remit of the Sport Performance section has been broad and includes mathematical and statistical evaluation of competitive sports performances, match- and notation-analysis, talent identification, training and selection or team organization. In addition, due to the academic interests of its section editors, they adopted a quality-assurance role for the Sport Performance section, invariably communicated through key editorials that subsequently shaped the editorial policy of the Journal. Key high-impact manuscripts are discussed, providing readers with some insight into what might lead an article to become a citation "classic". Finally, landmark articles in the areas of "science and football" and "notation analysis" are highlighted, providing further insight into how such articles have contributed to the development of sport performance research in general and the Journal of Sports Sciences in particular.

    2008-04-01

    Following its invention 25 years ago, PCR has been adapted for numerous molecular biology applications. Gene expression analysis by reverse-transcription quantitative PCR (RT-qPCR) has been a key enabling technology of the post-genome era. Since the founding of BioTechniques, this journal has been a resource for the improvements in qPCR technology, experimental design, and data analysis. qPCR and, more specifically, real-time qPCR has become a routine and robust approach for measuring the expression of genes of interest, validating microarray experiments, and monitoring biomarkers. The use of real-time qPCR has nearly supplanted other approaches (e.g., Northern blotting, RNase protection assays). This review examines the current state of qPCR for gene expression analysis now that the method has reached a mature stage of development and implementation. Specifically, the different fluorescent reporter technologies of real-time qPCR are discussed as well as the selection of endogenous controls. The conceptual framework for data analysis methods is also presented to demystify these analysis techniques. The future of qPCR remains bright as the technology becomes more rapid, cost-effective, easier to use, and capable of higher throughput.

    An overview of nearly thirty years development of waste gasification and pyrolysis technology is given, and some major general conclusions are drawn. The aim has been to give new developers an overview of earlier major attempts to treat MSW/RDF with thermochemical processes, gasification or pyrolysis. Research work in general is not covered, only R and D efforts that have led to substantial testing in pilot scale or demonstration. For further details, especially related to ongoing R and D, readers are referred to other recent reviews. The authors' view is that gasification of RDF with appropriate gas cleaning can play an important role in the future, for environmentally acceptable and efficient energy production. A prerequisite is that some of the major mistakes can be avoided, such as: (1) too rapid scale-up without experimental base, (2) unsuitable pretreatment of MSW to RDF and poor integration with material recycling, and (3) too limited gas/flue gas cleaning.

    1991-01-01

    Infrared imaging used in aerodynamic research evolved during the last 25 years into a rewarding experimental technique for investigation of body-flow viscous interactions, such as heat flux determination and boundary layer transition. The technique of infrared imaging matched well its capability to produce useful results, with the expansion of testing conditions in the entire spectrum of wind tunnels, from hypersonic high-enthalpy facilities to cryogenic transonic wind tunnels. With unique achievements credited to its past, the current trend suggests a change in attitude towards this technique: from the perception as an exotic, project-oriented tool, to the status of a routine experimental procedure.

    The areas in and along a 262-km length of the Susquehanna River in Pennsylvania were monitored for the presence of radioactive materials. This study began two months after the 1979 Three Mile Island (TMI) partial reactor meltdown; it spanned the next 25 y. Monitoring points included stations at the PPL Susquehanna and TMI nuclear power plants. Monthly gamma measurements document concentrations of radionuclides from natural and anthropogenic sources. During this study, various series of gamma-emitting radionuclide concentration measurements were made in many general categories of animals, plants, and other inorganic matter. Sampling began in 1979 before the first start-up of the PPL Susquehanna power plant. Although all species were not continuously monitored for the entire period, an extensive database was compiled. In 1986, the ongoing measurements detected fallout from the Chernobyl nuclear accident. These data may be used in support of dose or environmental transport calculations.

  5. Twenty-five years of progress in understanding pollination mechanisms in palms (Arecaceae)

    Barfod, Anders S.; Hagen, Melanie; Borchsenius, Finn

    2011-01-01

    Background With more than 90 published studies of pollination mechanisms, the palm family is one of the better studied tropical families of angiosperms. Understanding palm–pollinator interactions has implications for tropical silviculture, agroforestry and horticulture, as well as for our understanding of palm evolution and diversification. We review the rich literature on pollination mechanisms in palms that has appeared since the last review of palm pollination studies was published 25 years ago. Scope and Conclusions Visitors to palm inflorescences are attracted by rewards such as food, shelter and oviposition sites. The interaction between the palm and its visiting fauna represents a trade-off between the services provided by the potential pollinators and the antagonistic activities of other insect visitors. Evidence suggests that beetles constitute the most important group of pollinators in palms, followed by bees and flies. Occasional pollinators include mammals (e.g. bats and marsupials) and even crabs. Comparative studies of palm–pollinator interactions in closely related palm species document transitions in floral morphology, phenology and anatomy correlated with shifts in pollination vectors. Synecological studies show that asynchronous flowering and partitioning of pollinator guilds may be important regulators of gene flow between closely related sympatric taxa and potential drivers of speciation processes. Studies of larger plant–pollinator networks point out the importance of competition for pollinators between palms and other flowering plants and document how the insect communities in tropical forest canopies probably influence the reproductive success of palms. However, published studies have a strong geographical bias towards the South American region and a taxonomic bias towards the tribe Cocoseae. Future studies should try to correct this imbalance to provide a more representative picture of pollination mechanisms and their evolutionary implications across the entire family. PMID:21831852

  8. Twenty-five years of co-management of caribou in northern Québec

    Directory of Open Access Journals (Sweden)

    René Dion

    2003-04-01

    Full Text Available The Hunting Fishing and Trapping Co-ordinating Committee (HFTCC, created at the signature of the James Bay and Northern Quebec Agreement has been meeting regularly since 1977. Early in the process, it became clear that the perception of the role and powers of the Committee were not commonly shared by the native and non-native members of the Committee. Nevertheless, the Committee has been used primarily as a consultative body for wildlife related issues. Of all the files on which the Committee worked, Caribou management, (including the development of outfitting and commercial hunting for this species has been among one of the most discussed subjects during the meetings. An analysis of important decisions taken and of the process that led to them reveal that very rarely was the Committee able to formulate unanimous resolutions to the Governments concerning caribou management. In fact, only a few unanimous resolutions could be traced and many were ignored. This took place during a period of abundance and growth of the caribou herds. As a result, the Committee has gone through the cycle of growth of the George River Herd without a management plan, without a long term outfitting management plan and for the last 8 years, without a population estimate of the herds. This situation did not prevent the Committee from allocating quotas for a commercial hunt, open a winter sport hunt and to give permanent status to outfitting camps that were once established as mobile camps. It was hoped then that increased harvest would help maintain the population at carrying capacity. This short-term reaction however, never evolved into a more elaborate plan. Of course this must be looked at in the context of the HFTCC having a lot more to worry about than the Caribou. Although all members know of the population cycles of caribou, the decision process that must be triggered, should a crisis occur is not in place. This presently results into a polarization of concerned users (fall outfitters vs. winter outfitters, subsistence and sport hunters vs. commercial hunt, Outfitters Associations vs. HFTCC and eventually George River Herd users vs. Leaf River Herd users. The HFTCC may have to make difficult decisions during the coming years but did not gain much constructive experience through its first 25 years of existence. It is unfortunate that the authority of the Committee is binding the governments only in times of crisis when an upper limit of kill needs to be established. Because of the unpredictability of caribou herd numbers, the upper limit of kill should be established on a yearly basis. This would insure that the committee is fed information continuously in order to make informed decisions and would also re-establish the authority of the HFTCC over this resource.

    Models of community regulation commonly incorporate gradients of disturbance inversely related to the role of biotic interactions in regulating intermediate trophic levels. Higher trophic-level organisms are predicted to be more strongly limited by intermediate levels of disturbance than are the organisms they consume. We used a manipulation of the frequency of hydrological disturbance in an intervention analysis to examine its effects on small-fish communities in the Everglades, USA. From 1978 to 2002, we monitored fishes at one long-hydroperiod (average 350 days) and at one short-hydroperiod (average 259 days; monitoring started here in 1985) site. At a third site, managers intervened in 1985 to diminish the frequency and duration of marsh drying. By the late 1990s, the successional dynamics of density and relative abundance at the intervention site converged on those of the long-hydroperiod site. Community change was manifested over 3 to 5 years following a dry-down if a site remained inundated; the number of days since the most recent drying event and length of the preceding dry period were useful for predicting population dynamics. Community dissimilarity was positively correlated with the time since last dry. Community dynamics resulted from change in the relative abundance of three groups of species linked by life-history responses to drought. Drought frequency and intensity covaried in response to hydrological manipulation at the landscape scale; community-level successional dynamics converged on a relatively small range of species compositions when drought return-time extended beyond 4 years. The density of small fishes increased with diminution of drought frequency, consistent with disturbance-limited community structure; less-frequent drying than experienced in this study (i.e., longer return times) yields predator-dominated regulation of small-fish communities in some parts of the Everglades. ??

  11. Spatial variability studies in São Paulo, Brazil along the last twenty five years

    Directory of Open Access Journals (Sweden)

    2010-01-01

    Full Text Available Soil properties vary in space due to many causes. For this reason it is wise to know the magnitude and behaviour of the variability for adequate data analysis and decision making. Our work on spatial variability of soil properties in São Paulo, Brazil began in 1982 with a very simple soil sampling in a small field. Much progress has been made since then on sampling designs, field equipment and methods, and mostly on computation equipment and softwares. This paper reports the results corresponding to some aspects of this progress, as far as the field, analysis and computation work are concerned. The objective of this study was to illustrate the use of geostatistics in data analysis for three sampling conditions on long term no-tillage system. The analysis is done on a wide range of field scales, variables, sampling schemes as well as repeating sampling scheme for the same variable in different years. Semivariograms are compared for the same variables in different scales and sampling dates and depths as to provide a guide for sampling spacing and number of samples. Normalized crop yield parameters for many years are used in the discussion of time variability and on the use of yield maps to locate management zones. The time of the year in which measurements of soil physical properties are made affected the results both in terms of descriptive statistical and spatial dependence parameters. Crop yields changed (soybean decrease and maize increase with time of no-tillage but the real cause was not identified. The length of time with no-tillage affected the range of dependence for the main crops (increased for soybean, maize and oats and therefore increased the size of the homogeneous management zones. The evolution of the sampling grid from 20 m with 63 sampling points to 10 m with 302 sampling points allowed for a much better knowledge of the spatial variability of crop yields but it had the reverse effect on the spatial variability of soil physical properties.

  12. 1972-1997, Twenty-five years of energy and environmental history : lessons learned.

    Energy Technology Data Exchange (ETDEWEB)

    Drucker, H.

    1997-12-17

    Given the events of the past 25 years concerning energy and environmental issues and our reaction to them, what lessons can we learn? First, the individual American consumer wants and expects energy to be a stable commodity with low prices and easy availability. As evidenced by the heated debate over increasing the federal gasoline tax by $.05 per gallon (which would still leave Americans paying only one-third of what Europeans pay for gasoline), increases in energy prices elicit very strong public and political opposition. As further evidence, it has been argued that the general public support of the Gulf War was due, in part, to a recognition of the need to maintain a stable source of cheap oil from the region. The American public wants to maintain the benefits of cheap and abundant energy and expects its political leaders to make it happen. A second lesson is that if constraints on the energy supply do occur (e.g., the OPEC-imposed oil embargo) ardor environmental impacts from energy use do appear to be significant (e.g., SO{sub 2} and CO{sub 2} emissions), the preference is for a technology fix rather than a behavioral change. This is evidenced by our reliance on moving low-sulfur coal more than 1,000 miles from Wyoming to burn in Illinois power plants rather than reducing the demand for electricity with energy-efficient measures in residential, commercial, and industrial activities. National research programs to produce an automobile that gets 80+ miles per gallon take higher priority over working to get people to use mass transit to reduce their driving mileage. Americans expect that advanced technology can be relied upon to come up with solutions to energy and environmental problems without having to change their lifestyles. The experience with natural gas, in which a regulatory change (deregulation) was combined with technology developments (horizontal drilling and improved gas turbines for electricity generation) to increase available supply and hold prices down, has added to the confidence in the efficacy of technology fixes to solve energy and environmental problems. Third, it is difficult for government to tamper with energy markets and achieve the desired results.The energy system has shown itself to be a complex adaptive system that adjusts to even the most strenuous burdens in ways that are not easy to predict. Governmental attempts to predict and then prescribe the development of the future energy system are bound to meet with limited, if any, success. Rather, the more appropriate goal seems to be development of a robust and flexible energy system that can evolve and adjust to changing conditions. Given the experiences of the past and the lessons learned from these experiences, what might the future bring? Some predictions can be made with considerable confidence. It is highly likely that the trend of deregulating the energy sector will continue, with electricity deregulation a virtual certainty. It is also highly probable that the demand and consumption of energy from developing countries will soon surpass those of the US, Europe, and Japan, thus making them serious competitors for limited fossil fuel resources. In the environmental arena, some form of emission control of greenhouse gases from the energy sector will be agreed upon soon by the international community. More stringent regulations in the US for the emissions of some air and water pollutants are also likely. Preservation of biological diversity will also likely continue to be an issue of increasing importance.

    Bregni, Stefano

    2016-04-01

    The Modified Allan Variance (MAVAR) was originally defined in 1981 for measuring frequency stability in precision oscillators. Due to its outstanding accuracy in discriminating power-law noise, it attracted significant interest among telecommunications engineers since the early 1990s, when it was approved as a standard measure in international standards, redressed as Time Variance (TVAR), for specifying the time stability of network synchronization signals and of equipment clocks. A dozen years later, the usage of MAVAR was also introduced for Internet traffic analysis to estimate self-similarity and long-range dependence. Further, in this field, it demonstrated superior accuracy and sensitivity, better than most popular tools already in use. This paper surveys the last 25 years of progress in extending the field of application of the MAVAR in telecommunications. First, the rationale and principles of the MAVAR are briefly summarized. Its adaptation as TVAR for specification of timing stability is presented. The usage of MAVAR/TVAR in telecommunications standards is reviewed. Examples of measurements on real telecommunications equipment clocks are presented, providing an overview on their actual performance in terms of MAVAR. Moreover, applications of MAVAR to network traffic analysis are surveyed. The superior accuracy of MAVAR in estimating long-range dependence is emphasized by highlighting some remarkable practical examples of real network traffic analysis.

    Every medical practice manager has to deal with a certain amount of employee pessimism at times. But one overly pessimistic employee can spread his or her negativity to the entire medical practice team if the manager doesn't intervene. This article suggests practical strategies managers can use to deal effectively with a pessimistic, defeatist, gloomy, or cynical employee. It describes two kinds of pessimism medical practice managers may encounter and offers 25 specific management do's and don'ts for managing a pessimist. This article also offers managers guidance for firing a pessimistic employee, including sample language they can use. It provides 10 self-care strategies for practice managers so they can keep themselves from succumbing to an employee's negativity. It also suggests eight ways that pessimism can hurt the medical practice team and describes five kinds of negative thinking managers may encounter. Finally, this article explores defensive pessimism theory and the surprising benefits for managers of some pessimistic thinking.

    A Corynorhinus townsendii maternity roost located in an abandoned ranch house in central California was monitored for 25 y. Prior to the discovery of the bats in 1987, the house was broken into regularly and disturbance levels were quite high. Upon discovery of the roost, the house was fortified and vandalism was greatly reduced. The number of females and the number of volant young greatly increased during our study and was directly correlated with the decline in vandalism. Bats emerged from the house 43.6 (± 10.9 SD) min after local sunset. Bats emerged later in the evening during spring and fall, when it was warmer, and when it was windier. We also evaluated duration of emergence (47.11 [45.0–49.7] min), and seasonal patterns of re-entry into the roost. Several factors suggested that potential predation, most likely by owls, influenced both the timing and duration of evening emergences.

    2016-01-01

    Amyloid hypothesis of Alzheimer's disease (AD) has been long the primary one. During the 25-year history the concept has been dramatically changed. Accumulation of β-amyloid is associated not only with the disruption of its synthesis (as it seemed after the discovery of genetic mechanisms of some familial cases of AD) but rather with the disruption of its clearance and elimination from the brain tissue via the microcirculatory system. It has been recognized that soluble oligomers of β-amyloid, but not senile plaques that consisted of insoluble conjugates described by A. Alzheimer 100 years ago, play a key pathogenic role in the brain. Interrelation of vascular and degenerative processes is confirmed by common risk factors, clinical, neuroimaging, pathomorphological and experimental data. Insulin-resistance is also one of the links between AD degenerative and vascular processes. Based on the current state of the amyloid hypothesis, perspectives of new multimodal treatment strategies are discussed.

    The first study of Bahia Todos Santos (BTS) was reported by Walton in 1955. We conducted oceanographic studies in BTS since 1979. The BTS has a connection with a coastal lagoon named Estero de Punta Banda (EPB), two islands at the western portion and the Port of Ensenada. The general hydrographic characteristics are: In winter the water became homogeneous, less saline (33.6) low temperature (13°C), low oxygen (~3mL L-1) and rich in nutrient concentration. The isothermal top layer has relatively high temperature (>17°C) and oxygen concentration (>6mL L-1). The intermediate transition layer (seasonal thermocline) has minimum salinity, maximum oxygen and high stability. During fall there is distribution of heat from the surface layer to the entire water column. The thermic waves propagate with decrease amplitude in ~3 months, from surface to bottom water. The California Current flow generally southward off the western United States and northern Mexico and is one of the major coastal upwelling of the word oceans. The upwelling events in BTS appear regularly at the SW portion and were typically characterized by an increase in pCO2, decrease of O2, increase of nutrients and a lower temperature. Upwelling activity increases surface nutrient availability causing rise in the primary productivity and hence increased zooplankton biomass. The annual upwelling event which had a maximum strength on May, the seasonal warming and cooling, and the water advection were the dominant modifying processes for the variability of seawater characteristics. Higher salinities are located close to the coastline and lower off the bay. The levels of oxygen, alkalinity, pH and chlorophyll indicate that the maximum concentration of phytoplankton is located at the center of the bay. The nitrification support the primary productivity and the NO3 levels were below detection limits; the N/P ratio in 2005 was from 10 to 25; and for 2006 was below 5. There is a net enrichment of anthropogenic nutrients at BTS. The heavy metals and pesticides studies started since the early 80's with problems still to solve for Tl, Cd. There is a net Pb enrichment and higher Cr concentrations at the NE of the bay. The EPB is a wetland ~7 Km. long located at the SE part of the BTS. The EPB is a net source of DIP (deltaDIP = +0.13 mmol m-2 day-1), that brings agricultural runoff to the BTS. It is typically a hypersaline system during summer and a net heterotrophic (p-r = -14 mmol m-2 day-1), and a net denitrifying (nfix-denit = -2.1 mmol m-2 day-1) system. Some anomalies were in 2005 the presence of a huge red tide observed inside BTS (about 50% of the bay) that last for more than six months, this HAB's has killed many fishes (anoxia) and marine mammals. The hydrographic conditions during the red tide were, temperature anomalies higher than 2°C above normal; high nutrient concentration above the normal. In 2006 the values were normal again. The Port of Ensenada, increased in size and activities (tourism, transportation, coastguards for national security, cement industry, research) these developments generate some management problems, like the beach and coastline modification. The aground of the APL Panama, activates the management agencies to prevent and control pollution.

    Chohan, V

    2010-01-01

    The 25 year consolidation project was a result of a major re-thinking of CERN’s strategy for consolidating the LHC operation and the decision not to build a new PS Ring or a new Superconducting Proton Linac in early 2010. The work packages envisaged under this consolidation exercise came to a budget estimation of nearly 500 MCHF and were subjected to risk analyses to establish priorities and allocated funds based on limited spending profiles permitted under the CERN’s rolling Medium Term Plan, MTP.

  4. Twenty-five years on: still working toward a theory of conservation?

    Directory of Open Access Journals (Sweden)

    Paolo Fancelli

    2012-12-01

    Full Text Available During the 1980s conservation was still based on the scientific experimentation of the 1800s and only became operationally efficient in the 1960s. It has been interpreted and described in several ways, such as pure-conservative, a term which was first used at the beginning of 1971. However, conservation without the adjectival prefixes and resisting any form of retrospection has continued to advance both in laboratories and on archaeological sites, becoming more defined, elaborate and even authoritative in the aftermath of natural disasters. Nevertheless, it has had difficulty in being consid­ered within the traditional theories and practices of restoration; it is only recently that it has become an advantageous association. This is due to the fact that on the one hand, there has been growing awareness regarding the necessity of using conserva­tive intervention in the strict sense of the word and on the other it is evident that this intervention must be carried out in conjunction with other measures of an inhibitory and contrasting nature, using architectural instruments when faced with possibly inevitable deterioration. The result is a fruitful convergence between conservation and critical restoration in terms of a critical-conservative(or vice-versa approach.

    Full Text Available Abstract Background The socioeconomic gradient in obesity and overweight is amply documented. However, the contribution of different socioeconomic indicators on trends of body mass index (BMI over time is less well known. The aim of this study was to investigate the associations of education and income with (BMI from the late 1970s to the early 2000s. Methods Data were derived from nationwide cross-sectional health behaviour surveys carried out among Finns annually since 1978. This study comprises data from a 25-year period (1978–2002 that included 25 339 men and 25 330 women aged 25–64 years. BMI was based on self-reported weight and height. Education in years was obtained from the questionnaire and household income from the national tax register. In order to improve the comparability of the socioeconomic position measures, education and income were divided into gender-specific tertiles separately for each study year. Linear regression analysis was applied. Results An increase in BMI was observed among men and women in all educational and income groups. In women, education and income were inversely associated with BMI. The magnitudes of the associations fluctuated but stayed statistically significant over time. Among the Finnish men, socioeconomic differences were more complicated. Educational differences were weaker than among the women and income differences varied according to educational level. At the turn of the century, the high income men in the lowest educational group had the highest BMI whereas the income pattern in the highest educational group was the opposite. Conclusion No overall change in the socio-economic differences of BMI was observed in Finland between 1978 and 2002. However, the trends of BMI diverged in sub-groups of the studied population: the most prominent increase in BMI took place in high income men with low education and in low income men with high education. The results encourage further research on the pathways between income, education, living conditions and the increasing BMI.

  7. Twenty-five years of breast-feeding research in Midwifery.

    Dykes, Fiona

    2011-02-01

    This paper explores some of the significant changes that have taken place with regard to the protection, promotion and support of breast feeding during the past three decades. The period covered since the first issue of Midwifery in 1985, has been marked by some dramatic reversals of harmful discourses and detrimental practices with regard to infant and young child feeding and more specifically breast feeding. Midwifery has spanned this period with the publication of 80 papers on breast feeding. This collection of papers has both influenced and reflected upon changes in international and national breast-feeding strategies and practices. Six papers have been selected for a special virtual edition of Midwifery to reflect the diversity of breast-feeding research in terms of issues explored, methodology and country of origin (www.midwiferyjournal.com). Considerable progress is reflected in these papers. However, there are still enormous challenges ahead in working towards the optimisation of infant and young child feeding. In addition to continuing to conduct and collate robust scientific and epidemiological research we need further studies that explore the political, economic, socio-cultural and psychological factors influencing women's infant feeding practices. Our professional practice needs to continue to improve in order to provide women and families with appropriate support, encouragement and resources to enable them to breastfeed effectively. Finally, we need to continue to challenge the systems and approaches at organisational and community levels that impede women in their endeavours to feed their infants in optimum ways.

    Full Text Available Aim: To assess the quality of life (QoL and prevalence of psychological problems (PP in patients with neurological illness, and their correlation with functional abilities. Materials and Methods: Prospective cross-sectional study conducted in the neurological rehabilitation unit of tertiary research hospital in 30 consecutive hospitalized patients (21 men, age 16-55 years (34.63±11.87. Outcome Measure: WHOQoL-BREF was used to assess QoL. The prevalence of PP was recorded using Hospital Anxiety Depression Scale (HADS and General Health Questionnaire (GHQ-12. QoL and HADS scores were correlated with functional abilities using mean Barthel Index (BI Score. Results: The duration of illness was three to 30 months (10.63±7.83 and their primary diagnoses were stroke 12, traumatic spinal cord injury seven and non-traumatic spinal cord lesion 11. Twenty-two patients qualified for GHQ-12 caseness, with 15 patients having distress (score ≥15 and seven having severe problem and psychological distress (score≥20. Twenty five patients had abnormal anxiety and 17 had abnormal depression on HADS (abnormal = 8-21, with moderate to severe anxiety and depression (scores≥11 in nine and three patients respectively. The mean WHOQoL-BREF transformed scores (on WHOQoL 0-100 scale were (38.83±8.02, (50.76±9.79, (48.53±18.46 and (49.13±10.63 in physical, psychological, social, and environmental domains respectively. The social domain of QoL had significant correlation ( P < .05 with functional abilities. Conclusion: Patients with neurological disorders requiring inpatient rehabilitation have impaired QoL that affects all domains of life. There is high prevalence of psychological problems, including anxiety and depression. The social domain of QoL adversely affected functional abilities, but the correlation between PP and functional abilities was insignificant.

  13. Consecutive spawnings of Chinese amphioxus, Branchiostoma belcheri, in captivity.

    Directory of Open Access Journals (Sweden)

    Guang Li

    Full Text Available Cephalochordate amphioxus is a promising model animal for studying the evolutionary and developmental mechanisms of vertebrates because its unique phylogenetic position, simple body plan and sequenced genome. However, one major drawback for using amphioxus as a model organism is the restricted supply of living embryos since they are available only during spawning season that varies from a couple of days to several months according to species. Therefore we are aiming to develop methods for obtaining viable amphioxus embryos in non-spawning season. In the current study, we found that Branchiostoma belcheri could develop their gonads and spawn consecutively in the laboratory when cultured in a low density at a high temperature (25-28 °C supplied with sufficient food and proper cleanness. Among the approximate 150 observed animals, which spawned spontaneously between November and December 2011, 10% have spawned twice, 10% three times, and 80% four times, through April 2012. The quality and quantity of the gametes reproduced in the consecutive spawning have no obvious difference with those spawned once naturally. Spawning intervals varied dramatically both among different animals (from 1 to 5 months and between intervals of a single individual (from 27 to 74 days for one animal. In summary, we developed a method with which, for the first time, consecutive spawnings of amphioxus in captivity can be achieved. This has practical implications for the cultivation of other amphioxus species, and eventually will greatly promote the utilization of amphioxus as a model system.

    No studies have monitored the levels of faecal calprotectin (FC) during mesalazine suppository therapy for proctitis in ulcerative colitis (UC). To evaluate the value of consecutive monitoring of FC in patients with UC during mesalazine suppository therapy. One hundred and sixty patients with active inflammation limited to the rectum were treated with mesalazine 1 g suppository once daily for 8 weeks. Patients who achieved clinical remission were advised to maintain the treatment, and were followed up for further 40 weeks. FC levels were measured every 8 weeks during the study. At week 8, 118 patients (74%) went into clinical remission, of whom 88 achieved endoscopic healing. The median FC level significantly decreased in patients with clinical and endoscopic remission (both P suppositories. Serial monitoring of faecal calprotectin appears to be valuable for the prediction and early diagnosis of relapse during maintenance therapy. © 2015 John Wiley & Sons Ltd.

    2016-06-01

    Full Text Available Background/Aims: The acute hospital ward can be unfamiliar and stressful for older patients with impaired cognition, rendering them prone to agitation and resistive to care. Extant literature shows that music therapy can enhance engagement and mood, thereby ameliorating agitated behaviours. This pilot study evaluates the impact of a creative music therapy (CMT programme on mood and engagement in older patients with delirium and/or dementia (PtDD in an acute care setting. We hypothesize that CMT improves engagement and pleasure in these patients. Methods: Twenty-five PtDD (age 86.5 ± 5.7 years, MMSE 6/30 ± 5.4 were observed for 90 min (30 min before, 30 min during, and 30 min after music therapy on 3 consecutive days: day 1 (control condition without music and days 2 and 3 (with CMT. Music interventions included music improvisation such as spontaneous music making and playing familiar songs of patient's choice. The main outcome measures were mood and engagement assessed with the Menorah Park Engagement Scale (MPES and Observed Emotion Rating Scale (OERS. Results: Wilcoxon signed-rank test showed a statistically significant positive change in constructive and passive engagement (Z = 3.383, p = 0.01 in MPES and pleasure and general alertness (Z = 3.188,p = 0.01 in OERS during CMT. The average pleasure ratings of days 2 and 3 were higher than those of day 1 (Z = 2.466, p = 0.014. Negative engagement (Z = 2.582, p = 0.01 and affect (Z = 2.004, p = 0.045 were both lower during CMT compared to no music. Conclusion: These results suggest that CMT holds much promise to improve mood and engagement of PtDD in an acute hospital setting. CMT can also be scheduled into the patients' daily routines or incorporated into other areas of care to increase patient compliance and cooperation.

    Two consecutive community outbreaks of Salmonella enteritidis phage type 4 (PT4) traced to the same bakery occurred in Cardiff, Wales during August-September 1992. In the first outbreak, illness was associated with eating custard slices (odds ratio 23.8, 95% confidence interval 6.5-94.4, P sponge cake retained by a case and from two fresh cream cakes and four environmental swabs obtained at the bakery. This incident illustrates the hazard of widespread environmental contamination with salmonella and the need for thorough environmental cleansing for any premises implicated in an outbreak of food poisoning.

    This paper shows that effects of creative education program through the development of sliding bearings in the mechanical engineering department. In this program, the sliding bearings are designed and performance assessed at project team. In the beginning, the shape of a new sliding bearing is examined and suggested. When the suggested one obtains desired performance by the simulation program that is manufactured by CAD/CAM system and Machining Center. After estimation of geometry basis on shape measure, the produced one is measured the floating distance at performance test. The student can independently experience a consecutive improvement process by doing these processes twice in this program. The result with high attendance degree of satisfaction is gotten from the questionnaire about the member of a class.

    On 15 May 2005, a huge interplanetary coronal mass ejection (ICME) was observed near Earth. It triggered one of the most intense geomagnetic storms of solar cycle 23 (Dst peak = -263 nT). This structure has been associated with the two-ribbon flare, filament eruption, and coronal mass ejection originating in active region 10759 (NOAA number). We analyze here the sequence of events, from solar wind measurements (at 1 AU) and back to the Sun, to understand the origin and evolution of this geoeffective ICME. From a detailed observational study of in situ magnetic field observations and plasma parameters in the interplanetary (IP) medium and the use of appropriate models we propose an alternative interpretation of the IP observations, different to those discussed in previous studies. In our view, the IP structure is formed by two extremely close consecutive magnetic clouds (MCs) that preserve their identity during their propagation through the interplanetary medium. Consequently, we identify two solar events in H...

    Full Text Available One hundred and eighty five consecutive prostate specimens were studied. The predominant lesion noted was benign prostatic hyperplasia (B.P.H. (92.97%. The incidence of carcinoma was low, (7.02%. Conditions which can mimic and should be considered in the differential diagnosis of carcinoma, like basal cell hyperplasia, atypical hyperplasia and atrophy associated hyperplasia were noted in 10, 4 and 3 cases of B.P.H. respectively. None of these cases showed evidence of carcinoma. Corpora amylacea were noted in 38.91% of the cases of B.P.H. and were conspicuously absent in cases of carcinoma. Chronic prostatitis was frequently encountered (58% and metaplastic changes were seen in 11% of the cases.

    To assess the technical feasibility and surgical outcome of a 5 mm-ports technique in a consecutive series of women with endometrial cancer laparoscopically managed. Prospective collaborative cohort study (Canadian Task Force classification II-2). Two gynecologic oncology units of university hospitals. A series of consecutive patients undergoing laparoscopic hysterectomy, bilateral salpingo-oophorectomy, and pelvic lymphadenectomy for the treatment of endometrial cancer. A 10-mm zero-degree umbilical operative laparoscope and three 5-mm suprapubic trocars were used. The lymph nodes were removed with the use of a specimen bag through the umbilical port. Intraoperative and postoperative details and complications were prospectively collected. A total of 101 patients were enrolled. Twenty-two (21.8%) had a body mass index (BMI) of 30 kg/m2 or higher, and nine (8.9%) were severely obese (BMI > or =35 kg/m2). One hundred procedures (99%) were carried out entirely with only three 5-mm ancillary trocars. In one patient, a 5-mm trocar was replaced with a 10-mm trocar because of a lesion of the external iliac vein requiring the placement of vascular clips. One procedure needed to be converted to laparotomy. Intraoperative complications occurred in three patients (one bladder injury and one iliac vein injury, both managed laparoscopically, and one subcutaneous emphysema). Postoperative complications occurred in 10 (10%) patients. The only complication requiring a subsequent intervention was a symptomatic pelvic lymphocyst. No difference was found in surgical outcomes between obese women and those of ideal BMI. The use of only 5-mm ancillary trocars for the laparoscopic treatment of endometrial cancer can further minimize surgical invasiveness without compromising surgical efficacy and safety in patients with high BMI as well as for women with ideal BMI.

    Cardiovascular medication overdoses can be difficult to treat. Various treatment modalities are currently recommended. To describe patient outcomes and adverse events of high-dose insulin therapy in consecutive overdose patients in cardiogenic shock after implementation of a high-dose insulin protocol (1-10 U/kg/h, while avoiding or tapering off vasopressors). This is an observational consecutive case series of patients identified from a registry. Data were collected by retrospective chart review of patients treated by our toxicology service with this protocol from February 2007 until March 2010. Twelve patients were treated with high-dose insulin. The mean age was 36.5 years (SD 11.7). Seven patients had pre-existing vasopressor therapy, and all were tapered off vasopressors while on insulin. Two patients experienced pulseless electrical activity cardiac arrest prior to high-dose insulin therapy. Intravenous fat emulsion was given to two patients. The mean maximum insulin infusion rate was 8.35 U/kg/h (mean = 8.35, SD 6.34). The mean duration of insulin infusion was 23.5 h (SD 19.7). The mean duration of glucose infusion post-insulin was 25.2 h (SD 17.7). The primary toxins were β-blocker in five, calcium channel blocker in two, combined β-blocker/calcium channel blocker in two, tricyclic antidepressant in one, and polydrug in 2. CLINICAL OUTCOMES: Eleven of 12 patients survived. One patient expired 9 h into insulin therapy from cardiac arrest shortly after the insulin was stopped and a vasopressor re-initiated (protocol deviation). Six patients experienced a total of 19 hypoglycemic events. Hypokalemia (defined as insulin therapy. One patient was discharged with mild anoxic injury thought due to pulseless electrical activity arrest prior to insulin therapy. Three of these 12 patients have been previously described in published case reports. High-dose insulin therapy based on a 1-10 U/kg/h dosing guideline and recommending avoidance of vasopressors appears to be

    Insole pressure sensors capture the force distribution patterns during the stance phase while walking. By comparing patterns obtained from healthy individuals to patients suffering different medical conditions based on a given similarity measure, automatic impairment indexes can be computed in order to help in applications such as rehabilitation. This paper uses the data sensed from insole pressure sensors for a group of healthy controls to train an auto-encoder using patterns of stochastic distances in series of consecutive steps while walking at normal speeds. Two experiment groups are compared to the healthy control group: a group of patients suffering knee pain and a group of post-stroke survivors. The Mahalanobis distance is computed for every single step by each participant compared to the entire dataset sensed from healthy controls. The computed distances for consecutive steps are fed into the previously trained autoencoder and the average error is used to assess how close the walking segment is to the autogenerated model from healthy controls. The results show that automatic distortion indexes can be used to assess each participant as compared to normal patterns computed from healthy controls. The stochastic distances observed for the group of stroke survivors are bigger than those for the people with knee pain.

    Full Text Available Abstract Objective To describe management and clinical features observed in a patient's seven spontaneous pneumothoraces that developed during two consecutive pregnancies involving both hemithoraces. Materials and methods A 21 year old former smoker developed three spontaneous left pneumothoraces in the index pregnancy, having already experienced four right pneumothorax events in a prior pregnancy at age 19. Results Chest tubes were required in several (but not all hospitalizations during these two pregnancies. Following her fourth right pneumothorax, thoracoscopic excision of right apical lung blebs and mechanical pleurodesis was performed. The series of left pneumothoraces culminated in mini-thoracotomy and thoracoscopically directed mechanical pleurodesis. For both pregnancies unassisted vaginal delivery was performed with no adverse perinatal sequelae. With the exception of multiple pneumothoraces, there were no additional pregnancy complications. Conclusion Spontaneous pneumothorax in pregnancy is believed to be a rare phenomenon, yet the exact incidence is unknown. Here we present the first known case of multiple spontaneous pneumothoraces in two consecutive pregnancies involving both hemithoraces. Clinical management coordinated with obstetrics and surgical teams facilitated a satisfactory outcome for both pregnancies. The diagnosis of pneumothorax should be contemplated in any pregnant patient with dyspnea and chest pain, followed by radiographic confirmation.

    Tibial plateau fractures may result in significant limitations postoperatively. Studies have described outcomes of arthroscopic-assisted percutaneous fixation (AAPF) of these injuries but have rarely reported postoperative activity levels. Between 2009 and 2013, patients who sustained a lateral split, split depression, or pure depression type tibial plateau fracture (Schatzker types I-III fractures) and underwent outpatient AAPF were eligible for the study. Outcomes were assessed using Knee Injury and Osteoarthritis Outcome Score (KOOS), International Knee Documentation Committee (IKDC) Subjective Knee Evaluation Form, Lysholm score, and Marx activity score. Twenty-five consecutive patients were eligible for the study, and 22 (88%) were included in the final analysis, with average follow-up of 2.5 years (range, 1-5.2 years). Thirteen women and 9 men with an average age of 48.3 years (range, 23-65 years) comprised the study population. Average number of screws used for fixation was 2 (range, 1-4). The average depression was 8 mm preoperatively and 0.9 mm (range, 0-3 mm) postoperatively. Four patients (18%) had complications: 2 with hardware removal and 2 with postoperative deep venous thrombosis. Average postoperative Marx activity score was 5.7. Average postoperative KOOS Symptoms, Sports, and Quality of Life scores were 88 (range, 68-100), 85 (range, 45-100), and 77 (range, 50-100), respectively. Average IKDC and Lysholm scores were 81 (range, 55-97) and 87 (range, 54-100), respectively. The AAPF surgical technique, which was performed in an outpatient setting, facilitated excellent postoperative range of motion, outcomes, and activity scores with minimal complications.

    We report the case of a 9-year-old child operated for intermittent exotropia and V-pattern with a good result 2 months after bilateral Lateral Rectus Muscle Recession. The binocular vision was restored in primary position and down-gaze with excellent stereopsis at near and distance and a deviation of +4 PD in primary position. Three months later, the patient developed a consecutive esotropia of + 18 PD in primary position with diplopia in all gazes triggered by Amitriptyline treatment prescribed one month earlier for nocturnal enuresis. Diplopia was solved in time after anticholinergic medication cessation. During the recovery period, Fresnell prisms have been used in order to eliminate diplopia. Three months after diplopia onset, the binocular vision was restored showing a transitory and reversible effect of the Amitriptyline treatment. Fusion vulnerability can be a possible risk factor in developing diplopia and esotropia in patients treated with anticholinergic drugs.

    Drops are often used as building blocks for line and pattern printing where their interactions play an important role in determining the morphology and properties of deposited functional materials. In this study, the impact, spreading and oscillation of single and consecutively printed drops on substrates of different wettabilities are examined using a high speed camera. The results show that, for a single droplet impacting at a low Weber number, both the inertia and surface tension play important roles in the initial spreading stage before the droplet starts to oscillate. On a substrate of higher wettability, drop oscillation is damped down faster due to stronger viscous dissipation resulted from a longer liquid oscillation path. It is also found that when a drop impacting on an evaporating sessile drop sitting on a hydrophobic substrate, recoil of the combined drop is observed, in contrast to no recoil for the impact of a single drop under the same condition. Furthermore, a single-degree-of-freedom vibration model for the height of oscillating single and combined drops on a hydrophobic substrate is established. The results show that as viscosity of liquid increases, damping of drop oscillation becomes faster, and the combined drop oscillates longer compared to a single drop.

    For any real $x$ and any integer $k\\ge1$, we say that a set $\\mathcal{D}_{k}$ of $k$ distinct integers is a $k$-tuple jumping champion if it is the most common differences that occurs among $k+1$ consecutive primes less than or equal to $x$. For $k=1$, it's known as the jumping champion introduced by J. H. Conway. In 1999 A. Odlyzko, M. Rubinstein, and M. Wolf announced the Jumping Champion Conjecture that the jumping champions greater than 1 are 4 and the primorials 2, 6, 30, 210, 2310,.... They also made a weaker and possibly more accessible conjecture that any fixed prime $p$ divides all sufficiently large jumping champions. These two conjectures were proved by Goldston and Ledoan under the assumption of appropriate forms of the Hardy-Littlewood conjecture recently. In the present paper we consider the situation for any $k\\ge2$ and prove that any fixed prime $p$ divides every element of all sufficiently large $k$-tuple jumping champions under the assumption that the Hardy-Littlewood prime $k+1$-tuple conje...

    Cerebral angiography is an invasive procedure associated with a small, but definite risk of neurological morbidity. In this study we sought to establish the nature and rate of complications at our institution among a large prospective cohort of consecutive patients. Also, the data were analysed in an attempt to identify risk factors for complications associated with catheter angiography. Data were prospectively collected for a consecutive cohort of patients undergoing diagnostic cerebral angiography between January 2001 and May 2006. A total of 2,924 diagnostic cerebral angiography procedures were performed during this period. The following data were recorded for each procedure: date of procedure, patient age and sex, clinical indication, referring specialty, referral status (routine/emergency), operator, angiographic findings, and the nature of any clinical complication or asymptomatic adverse event (arterial dissection). Clinical complications occurred in 23 (0.79%) of the angiographic procedures: 12 (0.41%) significant puncture-site haematomas, 10 (0.34%) transient neurological events, and 1 nonfatal reaction to contrast agent. There were no permanent neurological complications. Asymptomatic technical complications occurred in 13 (0.44%) of the angiographic procedures: 3 groin dissections and 10 dissections of the cervical vessels. No patient with a neck dissection suffered an immediate or delayed stroke. Emergency procedures (P = 0.0004) and angiography procedures performed for intracerebral haemorrhage (P = 0.02) and subarachnoid haemorrhage (P = 0.04) were associated with an increased risk of complications. Neurological complications following cerebral angiography are rare (0.34%), but must be minimized by careful case selection and the prudent use of alternative noninvasive angiographic techniques, particularly in the acute setting. The low complication rate in this series was largely due to the favourable case mix. (orig.)

    The role of robotic instruments in mitral valve (MV) surgery continues to evolve. The purpose of this study was to assess the safety, efficacy, and scope of MV surgery using a lateral endoscopic approach with robotics (LEAR) technique. From 2006 to 2013, a dedicated LEAR team performed 1,257 consecutive isolated MV procedures with or without tricuspid valve repair or atrial ablation. The procedures were performed robotically through five right-side chest ports with femoral artery or ascending aortic perfusion and balloon occlusion. Operative videos and data were recorded on all procedures and reviewed retrospectively. The mean age of all patients was 59.3 ± 20.5 years, and 8.4% (n = 105) had previous cardiac surgery. The MV repair was performed in 1,167 patients (93%). The MV replacement was performed in 88 patients (7%), and paravalvular leak repair in 2 patients. Concomitant atrial ablation was performed in 226 patients (18%), and tricuspid valve repair in 138 patients (11%). Operative mortality occurred in 11 patients (0.9%) and stroke in 9 patients (0.7%). Predischarge echocardiograms demonstrated mild or less mitral regurgitation in 98.3% of MV repair patients. At mean follow-up of 50 ± 26 months, 44 patients (3.8%) required MV reoperation. Application of the LEAR technique to all institutional isolated MV procedures increased from 46% in the first year to more than 90% in the last 3 years. Mitral valve repair or replacement, including concomitant procedures, can be performed safely and effectively using the LEAR technique. With a dedicated robotic team, the vast majority of patients with MV disorders, either isolated or with concomitant problems, can be treated using the LEAR technique.

    Liposomal cisplatin (Lipoplatin) is a new agent, a cisplatin formulation that has been investigated in a number of studies and compared with cisplatin with respect to toxicity and effectiveness. It has been administered once weekly and in combination with a second agent, once every two weeks. The main outcome of the studies was that lipoplatin has no renal toxicity and is as equally effective as cisplatin. The present study investigated toxicity and effectiveness when lipoplatin is administered on two consecutive days, repeated every two weeks. Between January 2011 and November 2011, a total of 21 patients with histologically- or cytologically-confirmed non-small cell lung cancer (NSCLC) were enrolled in the study. All but two patients, who had not been pretreated, had received one or two series of chemotherapy and some had undergone radiotherapy. Lipoplatin monotherapy was infused for 8 h the first and second days and repeated every 2 weeks with the aim of administering 6 cycles. The dose per day was 200 mg/m(2). Eight out of 21 (38.10%) patients had a partial response, 9 (42.86%) had stable disease and 4 (19.05%) had progressive disease. Results showed that there was no renal failure toxicity and no other adverse reactions apart from grade 1 myelotoxicity in only 2 patients who had been heavily pretreated, and grade 1 nausea/vomiting in 4 patients. Liposomal cisplatin is an agent with negligible toxicity and reasonably high effectiveness even when administered to pretreated patients with NSCLC.

    Full Text Available Abstract Background High prevalence of depression has been reported in otorhinolaryngologic patients (ORL. However, studies using a semi-structured interview to determine the prevalence of depression in ORL are lacking. Therefore the present study sought to determine the depression prevalence in ORL applying a semi-structured diagnostic interview and to further characterize the pathopsychological and demographic characteristics of depression in these patients. Methods One-hundred inpatients of the otorhinolaryngologic department of a German university hospital participated voluntarily (age M = 38.8 years, SD = 13.9; 38.0% female. Depression was assessed using a clinical interview in which the International Diagnostic Checklist for depression (IDCL was applied. Patients completed the Brief Symptom Inventory (BSI which constitutes three composite scores and nine symptom scales and the Beck Depression Inventory (BDI. Multivariate analyses of variance, correlations and effect sizes were conducted. Results A prevalence of depression of 21.0% was determined, 38.0% of the depressed patients were female. Depressed patients showed higher scores on the BSI-scales "interpersonal sensitivity", "depression", "anxiety", "phobic anxiety" and "psychoticism" with medium effect sizes. Conclusions High prevalence of depression was found which is in accordance with results of prior studies. Depressed patients showed higher psychological distress as compared to non-depressed patients. The results call for carrying on in engaging in depression research and routine depression screening in ORL.

    To prospectively assess the feasibility and safety of holmium laser enucleation of the prostate (HoLEP) as day-case surgery for the treatment of benign prostatic hyperplasia. A prospective observational study was conducted by a single surgeon between June 2012 and October 2015. Except for patients ineligible for day-case surgery due to unstable cardiovascular disease, all patients with lower urinary tract symptoms presumably due to benign prostatic hyperplasia were consecutively included. HoLEP procedures were performed at 8AM, and patients were discharged before 8PM. The urinary catheter was removed at home the following morning. The monitoring of complications related with surgery included systematic assessment of perioperative complications, phone call within 48 hours after surgery, and follow-up visits after 1 and 3 months. Intent-to-treat univariate and multivariate analysis was performed to identify risk factors for day-case surgery failure. Ninety among 211 HoLEP performed by the surgeon were selected for day-case surgery (43%). Hospital stay was Day-case surgery failure rate (including prolonged hospitalization and readmissions within 48 hours) was 20.0% (18/90). The overall complication rate was 36.7%, with a Clavien III complication rate of only 3.3%. Monocentric design and limited number of patients are the main limitations of this work. This prospective evaluation shows that day-case HoLEP may be performed by a trained surgeon with an appropriate patient selection.

    Lumbar synovial cysts are a relatively common clinical finding. Surgical treatment of symptomatic synovial cysts includes computed tomography-guided aspiration, open resection and minimally invasive tubular resection. We report our series of 40 consecutive minimally invasive microscopic tubular lumbar synovial cyst resections. Following Institutional Review Board approval, a retrospective analysis of 40 cases of minimally invasive microscopic tubular retractor synovial cyst resections at a single institution by a single surgeon (B.D.B.) was conducted. Gross total resection was performed in all cases. Patient characteristics, surgical operating time, complications, and outcomes were analyzed. Lumbar radiculopathy was the presenting symptoms in all but 1 patient, who presented with neurogenic claudication. The mean duration of symptoms was 6.5 months (range, 1-25 months), mean operating time was 58 minutes (range, 25-110 minutes), and mean blood loss was 20 mL (range, 5-50 mL). Seven patients required overnight observation. The median length of stay in the remaining 33 patients was 4 hours. There were 2 cerebrospinal fluid leaks repaired directly without sequelae. The mean follow-up duration was 80.7 months. Outcomes were good or excellent in 37 of the 40 patients, fair in 1 patient, and poor in 2 patients. Minimally invasive microscopic tubular retractor resection of lumbar synovial cysts can be done safely and with comparable outcomes and complication rates as open procedures with potentially reduced operative time, length of stay, and healthcare costs. Patient selection for microscopic tubular synovial cyst resection is based in part on the anatomy of the spine and synovial cyst and is critical when recommending minimally invasive vs. open resection to patients.

    The demographic profile and complications are compared and contrasted for 150 consecutive parotidectomies. All patients were under the care of one surgeon (JDL) over a twenty-year period (1977-1997). The case records and contemporaneous database were analysed retrospectively. 111 (74%) procedures were performed for tumours and 39 (26%) for inflammatory disease. The incidence of unexpected permanent facial nerve palsy was 1.8% in the tumour group and zero in the inflammatory group. The overall unexpected palsy rate was 1.3%. Transient paralysis was more common in the inflammatory group than the tumour group (61.5% compared with 33.3%, P<0.02) and was more likely to be panfacial (48.7% compared with 17.1%, P<0.0002). The overall incidence of Frey's syndrome was less than 20% and both salivary fistulae and sialocoeles were infrequent.

Methods Retrospective case analysis of 472 patients with traumatic hyphaema admitted to the University College Hospital, Ibadan between January 1997 and December 2006. Results The home was the single most frequent place of injury for all cases and for 75% of cases in children aged 0–10 years. Injuries that occurred at school comprised about one-fifth of cases. Sport-related injuries were uncommon. The most common activities preceeding injuries were play, corporal punishment and assault. Stones, sticks and whiplash were the agents that caused traumatic hyphaema. Occupational-related hyphaema that caused injuries was mostly in farmers and artisans, few of whom used protective goggles. The majority of patients were males. Children and young adults aged ≤ 20 years comprised 63.6% of patients. A total of 336 (76% eyes had at least one surgical intervention. While 298 (73.2% patients had visual acuity (VA less than 6/60 at presentation, 143 (37.0% of eyes had visual acuity (VA Conclusion The injuries leading to traumatic hyphaema occur mostly at home and school, and frequently affect children and young adolescents. Over one-third resulted in blindness in the affected eye. The focus should be on prevention of stick-related eye injuries at these locations and improving access to eye health services for patients who sustained eye injuries.

    Sentinel lymph node biopsy is the most important tool available for node staging in patients with melanoma. To analyze sentinel lymph node detection and dissection with radio guidance from a portable gamma camera. To assess the number of complications attributable to this biopsy technique. Prospective observational study of a consecutive series of patients undergoing radioguided sentinel lymph node biopsy. We analyzed agreement between nodes detected by presurgical lymphography, those detected by the gamma camera, and those finally dissected. A total of 29 patients (17 women [62.5%] and 12 men [37.5%]) were enrolled. The mean age was 52.6 years (range, 26-82 years). The sentinel node was dissected from all patients; secondary nodes were dissected from some. In 16 cases (55.2%), there was agreement between the number of nodes detected by lymphography, those detected by the gamma camera, and those finally dissected. The only complications observed were seromas (3.64%). No cases of wound dehiscence, infection, hematoma, or hemorrhage were observed. Portable gamma-camera radio guidance may be of use in improving the detection and dissection of sentinel lymph nodes and may also reduce complications. These goals are essential in a procedure whose purpose is melanoma staging. Copyright © 2014 Elsevier España, S.L.U. and AEDV. All rights reserved.

    To investigate the etiology of pleural effusions (PE) in adults and the accuracy of pleural fluid (PF) cytology and cultures in malignant and infectious PE, respectively. Retrospective analysis of all consecutive patients with PE undergoing diagnostic thoracentesis during the last 19 years in a university hospital. The leading causes of PE among the 3,077 patients were: cancer (27%), heart failure (21%), pneumonia (19%), tuberculosis (9%), abdominal surgery (4%), pericardial diseases (4%) and cirrhosis (3%). Tuberculosis was the most common etiology in patients <34 years of age (52%), whereas heart failure predominated in octogenarians (45%). The most common primary tumors in malignant PE were lung (37%) and breast (16%). The overall accuracy of PF cytology was 59%, although it was significantly lower in mesotheliomas (27%) and squamous cell lung cancer (25%). In infectious PE, only 30% of cultures yielded positive results, a percentage which increased two-fold (66%) in purulent fluids (empyemas). Viridans streptococci were the most commonly isolated pathogens (25.5%). The sensitivity of solid media cultures of PF for Mycobacterium tuberculosis was low (18.5%). Three-quarters of patients with PE in whom a diagnostic thoracentesis was indicated had cancer, heart failure, pneumonia or tuberculosis. PF cytology and cultures give false negative results in a significant number of cases. Copyright © 2013 SEPAR. Published by Elsevier Espana. All rights reserved.

    To assess the feasibility of routine use of electromagnetic image guidance systems in orbital decompression. Six consecutive patients underwent stereotactic-guided three wall orbital decompression using the novel Fusion ENT Navigation System (Medtronic), a portable and expandable electromagnetic guidance system with multi-instrument tracking capabilities. The system consists of the Medtronic LandmarX System software-enabled computer station, signal generator, field-generating magnet, head-mounted marker coil, and surgical tracking instruments. In preparation for use of the LandmarX/Fusion protocol, all patients underwent preoperative non-contrast CT scan from the superior aspect of the frontal sinuses to the inferior aspect of the maxillary sinuses that includes the nasal tip. The Fusion ENT Navigation System (Medtronic™) was used in 6 patients undergoing maximal 3-wall orbital decompression for Graves' orbitopthy after a minimum of six months of disease inactivity. Preoperative Hertel exophthalmometry measured more than 27 mm in all patients. The navigation system proved to be no more difficult technically than the traditional orbital decompression approach. Electromagnetic image guidance is a stereotactic surgical navigation system that provides additional intraoperative flexibility in orbital surgery. Electromagnetic image-guidance offers the ability to perform more aggressive orbital decompressions with reduced risk.

    Highlights: •We evaluated myocardial perfusion by dual energy computed tomography (DECT). •We included patients with intermediate to high likelihood of coronary artery disease. •Stress myocardial perfusion by DECT had a reliable accuracy for the detection of ischemia. •Stress myocardial perfusion with DECT showed an incremental value over anatomical evaluation. •DECT imaging was associated to a significant reduction in radiation dose compared to SPECT. -- Abstract: Purpose: We sought to explore the diagnostic performance of dual energy computed tomography (DECT) for the evaluation of myocardial perfusion in patients with intermediate to high likelihood of coronary artery disease (CAD). Materials and methods: Consecutive patients with known or suspected CAD referred for myocardial perfusion imaging by single-photon emission computed tomography (SPECT) constituted the study population and were scanned using a DECT scanner equipped with gemstone detectors for spectral imaging, and a SPECT. The same pharmacological stress was used for both scans. Results: Twenty-five patients were prospectively included in the study protocol. The mean age was 63.4 ± 10.6 years. The total mean effective radiation dose was 7.5 ± 1.2 mSv with DECT and 8.2 ± 1.7 mSv with SPECT (p = 0.007). A total of 425 left ventricular segments were evaluated by DECT, showing a reliable accuracy for the detection of reversible perfusion defects [area under ROC curve (AUC) 0.84 (0.80–0.87)]. Furthermore, adding stress myocardial perfusion provided a significant incremental value over anatomical evaluation alone by computed tomography coronary angiography [AUC 0.70 (0.65–0.74), p = 0.003]. Conclusions: In this pilot investigation, stress myocardial perfusion by DECT demonstrated a significant incremental value over anatomical evaluation alone by CTCA for the detection of reversible perfusion defects.

    Optimal management of eumycetoma, a severely debilitating chronic progressive fungal infection of skin, disseminating to bone and viscera, remains challenging. Especially, optimal antifungal treatment and duration are ill defined. We conducted a monocentric retrospective study of 11 imported cases of eumycetoma treated by voriconazole or posaconazole for at least 6 months. Response to treatment was assessed through evolution of clinical and magnetic resonance imaging (MRI). (1→3) ß-D-glucan (BG) and positron emission tomography using [18F] fluorodeoxyglucose (PET/CT) results were also assessed. Identified species were Fusarium solani complex (n = 3); Madurella mycetomatis, (n = 3), and Exophiala jeanselmei, (n = 1). Moreover, two coelomycetes and one phaeohyphomycetes strains without species identification were retrieved. Serum BG and PET/CT were abnormal in 7/8 and 6/6 patients tested, respectively. Patients received last generation azoles for a mean duration of 25.9±18 months. Complete response (major clinical and MRI improvement) was observed in 5/11 patients, partial response (minor MRI improvement or stable MRI findings) in 5 and failure (MRI evidence of disease progression) in one, with a 73±39 [6-132] months mean follow-up. Relapse occurred in 2 patients after treatment discontinuation. Optimal outcome was associated with fungal species, initiation of last generation triazole therapy (eumycetoma.

    Full Text Available Abstract Background Combined kidney pancreas transplantation (PTx evolved as excellent treatment for diabetic nephropathy. Infections remain common and serious complications. Methods 217 consecutive enteric drained PTxs performed from 1997 to 2004 were retrospectively analyzed with regard to bloodstream infection. Immunosuppression consisted of antithymocyteglobuline induction, tacrolimus, mycophenolic acid and steroids for the majority of cases. Standard perioperative antimicrobial prophylaxis consisted of pipercillin/tazobactam in combination with ciprofloxacin and fluconazole. Results One year patient, pancreas and kidney graft survival were 96.4%, 88.5% and 94.8%, surgical complication rate was 35%, rejection rate 30% and rate of infection 59%. In total 46 sepsis episodes were diagnosed in 35 patients (16% with a median onset on day 12 (range 1–45 post transplant. Sepsis source was intraabdominal infection (IAI (n = 21, a contaminated central venous line (n = 10, wound infection (n = 5, urinary tract infection (n = 2 and graft transmitted (n = 2.

    Objective: To study the CT characteristics of solitary focal organizing pneumonia (FOP). Materials and methods: Chest CT of consecutive 45 patients (34 males and 11 females, median age: 56 years) with confirmed FOP were analyzed. The CT features between large FOP (>3 cm, n = 27) and small FOP (≤3 cm, n = 18) were compared. Results: FOP lesions predominately located in peripheral lungs (86.7%), with the right lower lobe being most common lobe (44.4%). No lesion mainly located in the inner 1/3 of lungs. All large lesions were polygon in shape and had an irregular margin, while small lesions were more likely to be round or oval with an irregular or smooth border. Air bronchogram or small bubble-like lucency was present in majority of the lesions. 42.2% of lesions had incompact internal structure with inhomogeneous density besides air component. Most lesions were associated with a contraction or convergence of surrounding vessels; while no pulmonary vessel was interrupted abruptly by a small FOP lesion. Majority of large lesions had broad contact with the pleura, while only one patient had mild pleural effusion. Mild mediastinal lymph nodes enlargement was present in about 1/5 of the patients. Conclusion: Compared with the known CT features of lung cancer, our results suggest differential diagnosis can often be made for large FOP, while small FOP may resemble lung cancer.

    Acute pancreatitis can be triggered by a variety of factors ranging from short lasting to sustained disruptions. It is plausible that the characteristics and course of disease differ among etiologies. Data distinguishing characteristics of patients with pancreatitis of biliary, alcoholic, idiopathic or other origin are scarce and conflicting. To compare patients' characteristics, baseline parameters on admission, and outcome in patients with an episode of acute pancreatitis in whom the etiology was thoroughly determined. Retrospective study. Single center. Three-hundreds and 91 consecutive episodes of acute pancreatitis through the years 2008 to 2011. Gender, age, body mass index, Charlson comorbidity index, history of pancreatitis, heart rate, blood pressure, plasma lipase, hematocrit, plasma creatinine, white blood cell count, rate of persistent organ failure and necrosis, maximum C-reactive protein, duration of hospitalization, mortality. There were marked differences between the groups. Biliary etiology was associated with higher age and body weight, female predominance, higher plasma lipase, and a favourable outcome. Alcoholic etiology had male predominance, a tendency for initial hemoconcentration, a lower plasma lipase, and the highest rate of necrosis. Idiopathic etiology had the highest rate of persistent organ failure and the highest mortality. Biliary, alcoholic and idiopathic acute pancreatitis should be treated as distinct entities. While alcoholic episodes have the highest risk of necrosis, the worst outcome was observed in the idiopathic group. Hence, finding no causality for an episode of acute pancreatitis after thorough investigation might be a predictor for poor outcome. Larger studies are warranted to confirm this.

    Compared to other surgical areas, laparoscopic liver resection (LLR) has not been widely implemented and currently less than 20% of hepatectomies are performed laparoscopically worldwide. The aim of our study was to evaluate the feasibility, and the ratio of implementation of LLR in our department. We analyzed a prospectively maintained database of 749 liver resections performed during the last 10-year period in a single centre. A total of 150 (20%) consecutive pure LLR were performed between 2005 and 2015. In 87% of patients the indication was the presence ofprimary or metastatic liver malignancy. We performed 30 major hepatectomies (20%) and (80%) were minor resections, performed in all liver segments. Twelve patients were operated twice and 2 patients underwent a third LLR. The proportion of LLR increased from 12% in 2011 to 62% in the last year. Conversion rate was 9%. Overall morbidity rate was 36% but only one third were classified as severe. The 90-day mortality rate was 1%. Median hospital stay was 4 days and the rate of readmissions was 6%. The implementation of LLR has been fast with morbidity and mortality comparable to other published series. In the last 2 years more than half of the hepatectomies are performed laparoscopically in our centre. Copyright © 2017 AEC. Publicado por Elsevier España, S.L.U. All rights reserved.

    Minimally invasive surgery represents the gold standard for the management of deep infiltrating endometriosis (DIE) involving the rectovaginal septum (RVS). This analysis aimed to evaluate the feasibility of robotic-assisted laparoscopy (RAL) and clinical outcomes in terms of long-term complications, pain relief, and recurrence rate for the treatment of DIE of the RVS. A prospective cohort study of robotic procedures was performed between October 2010 and July 2014, including removal of endometriotic nodules from the RVS with rectal shaving alone or in combination with accessory procedures. In all cases, the revised American Society for Reproductive Medicine (rASRM) score for endometriosis was >40 points (stage IV). Twenty-five consecutive patients underwent RAL, with a successful complete nodule debulking by the wall shaving technique. Pathology confirmed the adequacy of the surgical specimen and the median largest endometriotic nodule was of 21 mm (range, 10-60 mm), with free margins in all cases. The median operative time from skin opening to closure was 174 minutes (range, 75-300 minutes), and blood loss was close to 0 mL. The median revised Enzian score for location A (RVS) was 2 (range, 1-3). The most frequent Enzian class was A2B0C0 (48%), followed by A3B0C0 (12%). In 3 cases (12%), partial vaginal resection was required to remove endometriotic nodules of the RVS (1 each in classes A3B0C1FI, A3B0C0FO, and A3B0C0). No intraoperative complications occurred. This series has a median long-term follow up of 22 months (range, 6-50 months) currently available with an optimal operative time, demonstrating good long-term outcomes. Our data support robotics as a safe and attractive alternative for comprehensive surgical treatment of DIE.

In the present study, we used transcranial direct current stimulation (tDCS applied to cerebellar and prefrontal cortices to improve the neurophysiological performances of patients with euthymic BD.Methods: Twenty-five outpatients with BD underwent open-label prefrontocerebellar tDCS for 3 consecutive weeks. Neurophysiological performances were assessed through the examination of the P3b and P3a subcomponents of P300 event-related potential at baseline and after stimulation.Results: Compared to baseline, P3b component after tDCS showed significantly higher amplitude and shorter latency (latency: Fz P=0.02, Cz P=0.03, and Pz P=0.04; amplitude: Fz P=0.24, Cz P=0.02, and Pz P=0.35.Conclusion: In our sample of patients with euthymic BD, concomitant prefrontoexcitatory and cerebellar-inhibitory modulations led to improved brain information processing stream. This improvement may at least partially result from neuroplastic modulation of prefrontocerebellar circuitry activity.

    To evaluate the feasibility in clinical practice of alternating chemo-radiotherapy in locally advanced head and neck cancer patients. From August 1993 to April 1998 at the Division of Medical Oncology of Parma, 48 consecutive patients were observed, and 38 (79%) started the Merlano chemo-radiotherapy. The characteristics of the patients were: males (32, 84%); median age, 57 years; PS <2 (32, 84%). The primary sites were the oropharynx (18, 47%), oral cavity (8, 21%), hypopharynx (7, 19%), larynx (5, 13%); stage IV disease was present in 29 (76%) patients. Twenty-five (66%) patients were married, and 24 (63%) resided outside of the city. The compliance was very low: 21 patients (55%) performed all the programmed cycles of chemotherapy, whereas only 5 patients (13%) performed the chemo-radiotherapy at full doses without any delay. The objective responses were 3 (8%) complete and 21 (55%) complete plus partial responses. Failures were 2 (5%) stable disease and 2 (5%) progressive disease, and the response was not assessable in 10 (26%). The median duration of the response was 8 months. The median overall survival and the time to progression were 18 and 13 months, respectively; the 5-year overall and relapse-free survival were 36% and 26%, respectively. Nine (24%) patients were still alive as of August 30, 2001, 8 (21%) of them without progression. Twenty-six patients (68%) died with a local-regional relapse. One patient (3%) died for a second cancer. Grade 3-4 hematologic toxicity was leukopenia (n = 25, 66%) and thrombocytopenia (n = 9, 24%); grade 3-4 non-hematologic toxicity was diarrhea (n = 3, 8%) and mucositis (n = 2, 5%). Two patients (5%) died for intestinal infarction and perforation possibly related to treatment. Compliance to the chemo-radiotherapy was very poor. The response rate was lower than that reported in clinical trials, whereas overall survival was comparable. The alternating chemo-radiotherapy is a very complex treatment that cannot be easily

    Colonoscopic polypectomy is the best diagnostic and therapeutic tool to detect and prevent colorectal neoplasms. However, previous studies have reported that 17% to 28% of colorectal polyps are missed during colonoscopy. We investigated the miss rate of neoplastic polyps and the factors associated with missed polyps from quality-adjusted consecutive colonoscopies. We reviewed the medical records of patients who were found to have colorectal polyps at a medical examination center of the Kangbuk Samsung Hospital between March 2012 and February 2013. Patients who were referred to a single tertiary academic medical center and underwent colonoscopic polypectomy on the same day were enrolled in our study. The odds ratios (ORs) associated with polyp-related and patient-related factors were evaluated using logistic regression analyses. A total of 463 patients and 1,294 neoplastic polyps were analyzed. The miss rates for adenomas, advanced adenomas, and carcinomas were 24.1% (312/1,294), 1.2% (15/1,294), and 0% (0/1,294), respectively. Flat/sessile-shaped adenomas (adjusted OR, 3.62; 95% confidence interval [CI], 2.40-5.46) and smaller adenomas (adjusted OR, 5.63; 95% CI, 2.84- 11.15 for ≤5 mm; adjusted OR, 3.18; 95% CI, 1.60-6.30 for 6-9 mm, respectively) were more frequently missed than pedunculated/sub-pedunculated adenomas and larger adenomas. In patients with 2 or more polyps compared with only one detected (adjusted OR, 2.37; 95% CI, 1.55-3.61 for 2-4 polyps; adjusted OR, 11.52; 95% CI, 4.61-28.79 for ≥5 polyps, respectively) during the first endoscopy, the risk of missing an additional polyp was significantly higher. One-quarter of neoplastic polyps was missed during colonoscopy. We encourage endoscopists to detect smaller and flat or sessile polyps by using the optimal withdrawal technique.

METHODS: Forty four consecutive orthotopic liver transplants performed from October 2009 to December 2010 were analyzed. The patients (38 male and eight female were divided into two groups: group A, survivors, and group B, non-survivors. Fifty percent of group A patients were Chid-Pugh C, 40% Chid-Pugh B and 10% Chid-Pugh A. In group B, 52% of the patients were Chid-Pugh C, 41% Chid-Pugh B, and 17% Chid-Pugh A. All orthotopic liver transplants were performed by the piggy-back technique without a portacaval shunt in an anhepatic phase. ALT, AST, LDH and lactate levels were determined preoperatively, at five, 60 minutes after arterial revascularization of the graft and 24 and 48 hours after the end of the surgery.( or: after the surgery was finished. RESULTS: There were no preoperative clinical differences (Child and Meld between the two groups. The times of warm and hypothermal ischemia were similar for both groups (p>0.05. Serum aminotransferases levels at five and 60 minutes after arterial revascularization of the graft were similar (p>0.05 for both groups, as also were lactate levels at the time points studied. There was no significant difference in Δ lactate between groups at any time point studied (p>0.05. No significant difference was observed between groups during the first 24 and 48 hours after surgery (p>0.05. CONCLUSION: No significant difference in any of the parameters studied was observed between groups. Under the conditions of the present study and considering the parameters evaluated, no direct relationship was detected between the intraoperative situation and the type of evolution of the patients of the two groups studied.

    AIM: To evaluate the efficacy and safety of three consecutive monthly injections of intravitreal ranibizumab for the treatment of polypoidal choroidal vasculopathy(PCV) in Korea.METHODS: A retrospective chart review of 25 patients(27 eyes) with PCV was conducted. Patients received three initial monthly intravitreal injections(0.5 mg) of ranibizumab and were monitored monthly for 12 mo from January 2010 to October 2011. Reinjection of ranibizumab after three initial monthly loading was administered on an as-needed basis, guided by the optical coherence tomography(OCT), fluorescein angiography(FA) and indocyanine green angiography(ICGA). The main outcomes were the changes of the mean best corrected Snellen visual acuity(VA), central macular thickness(CMT) by OCT, the changes of polyps and branching vascular network by FA and ICGA, and total number of injections received by patients during the 12 mo.RESULTS: The mean best corrected Snellen visual acuities at baseline, 1, 3, 6 and 12 mo after primary injection were 0.77 ±0.59, 0.76 ±0.53, 0.70 ±0.47, 0.63 ±0.43,0.61 ±0.43, 0.62 ±0.42 log MAR, respectively, and showed significant improvement at 3, 6, 12mo(P =0.003, P =0.002,P =0.018, Wilcoxon signed-rank test). The mean CMT at baseline, 1, 2, 3, 6, and 12 mo was 312.41 ±66.38 μm,244.59 ±71.47 μm, 232.32 ±69.41 μm, 226.69 ±69.03 μm,228.62 ±37.07 μm, 227.59 ±51.01 μm respectively, and showed significant reduction(all P <0.001, Wilcoxon signed-rank test). Polypoidal lesions resolved on ICGA in 3 eyes(11.1%) and a branching vascular network remained in all 24 eyes(88.9%). A total of 106 injections were given in the 12-month period, which equaled to a mean of 3.92(range, 3-6) times. Sixteen of the 27 treatedeyes had additional 1.56 ±0.91 injections. The others(11eyes) had just 3 consecutive injections.CONCLUSION: An initial loading dose of three monthly ranibizumab injections is a safe and effective method in treating PCV, with visual and anatomical

    Lipoatrophia semicircularis is an infrequent condition characterized by semicircular depressions of the anterolateral aspects of the thighs. The origin of this peculiar variant of lipoatrophy is unknown, although repeated mechanical trauma on the affected thighs has been advocated in many cases. A 57-year-old woman presented with a 1-year history of two bilateral, parallel, symmetric, asymptomatic depressions on the anterolateral aspect of her thighs. The patient worked as a cashier, permanently seated and almost always wearing trousers. The localization of lesions and their linear artifactual appearance perfectly matched with the strangling folds formed by trousers while being sat. Echotomographic examination revealed a loss of the normal echogenic pattern in the subcutaneous tissue of the affected areas. We believe that the anatomical adipose constitution of women's thighs predisposes that a persistent mechanical pressure induced by wearing trousers while being sat for long periods of time, originates a relative impaired circulation on a tenuous perfused tissue, and induces the development of lipoatrophia semicircularis.

    A unit is presented that provides the neurosurgeon with CT, MRI, x-ray, DA, and DSA compatible headholder and multimodality image localization as well as freedom of choice for surgical approach on patient's intraoperative positioning. The unit consists of a carbon fiber ring-shaped headholder which allows free selection for location of three or four fixation pins, avoiding interference with the flap sites or craniotomy. The base ring is mounted intraoperatively on a special adapter that allows any patient positioning including supine, lateral, prone, 3/4 prone, sitting, etc. Surgical draping can be performed given a completely sterile field. An arc/quadrant localizing device can be mounted on any four alternative positions according to the neurosurgeon's preference. A PC compatible software gives the setting for any possible mounting. Intraoperative the localizing unit can be used in a 'fixed' permanent setting or as a 'non-fixed' system to provide intraoperative three-dimensional orientation. Different are adapted instruments which give the unit further capabilities, especially 'bayonet' type brain retractors (cylinders and speculum) that allows the neurosurgeon to keep the surgical corridor unobstructed from the arc. As an alternative, in the 'non-fixed' setting, self-retaining arms are fixed to the base ring and brain retractors and conventional microsurgical technique can be used without any mechanical obstruction. This article presents the unit details, methodology and the clinical experience in 103 consecutive cases of 'open stereotaxis' for resection or internal decompression of deep seated or near eloquent area lesions.

    The modern era of breast augmentation and reconstruction began in 1963, with the introduction of silicone implants by Cronin and Gerow. To date, the demand for cosmetic augmentation continues to increase exponentially. However, whilst the surgical techniques and quality of mammary prosthesis have improved dramatically in recent years, patients are still confronted with significant potential complications. We performed a retrospective study of 1400 consecutive primary breast augmentations performed between March 1995 and March 2009 by a single surgeon. We specifically examined the incidence of capsular contracture and the possible causative factors. Follow up ranged from 1 to 16 years. The mean age at the time of surgery was 32.8 years and fill volume was between 195 ml and 800 ml. Our capsular contracture rate was in the order of 26.9%. BMI >30, fill volumes >350 ml, smoking and alcohol consumption did not significantly increase capsular contracture rate. Implant type, pregnancy, infection and delayed haematoma significantly increased the risk of capsular contracture. Our series has given us a unique insight into the frequency of capsular contracture and identified several risk factors. To our knowledge, this is the first report of pregnancy having a significant effect on capsular contracture. We now counsel patients thoroughly into the detrimental effects of pregnancy on the implant. Copyright © 2011 British Association of Plastic, Reconstructive and Aesthetic Surgeons.

    2003-09-01

    To assess the reasons for and outcomes of referrals concerning the foreskin, 100 consecutive patients seen in paediatric clinics were followed to discharge. 18 referrals were for circumcision on religious grounds. Of the other 82, the main reason for referral was non-retractability or phimosis. At clinic, 24 (29%) of these were deemed normal for age, 31 (38%) were treated with topical steroid (successfully in 25), 9 (11%) were listed for preputioplasty, 7 (9%) were listed for adhesiolysis, 7 (9%) were listed for circumcision, and 4 were listed for other forms of surgery. 6 patients were identified as having balanitis xerotica obliterans (BXO), a condition that had not been suggested on referral. With the advent of new treatments for foreskin disorders, circumcision is decreasingly necessary. Knowledge of the natural history of the foreskin, and the use of topical steroids, could shift the management of paediatric foreskin problems from the hospital outpatient department to primary care. BXO is not sufficiently recognized as a form of phimosis that requires operation.

    Our aim was to examine the clinical and radiographic outcomes in 257 consecutive Oxford unicompartmental knee arthroplasties (OUKAs) (238 patients), five years post-operatively. A retrospective evaluation was undertaken of patients treated between April 2008 and October 2010 in a regional centre by two non-designing surgeons with no previous experience of UKAs. The Oxford Knee Scores (OKSs) were recorded and fluoroscopically aligned radiographs were assessed post-operatively at one and five years. The median age of the 238 patients was 65.0 years (interquartile range (IQR) 59.0 to 73.0), the median body mas index was 30.0 (IQR 27.5 to 33.0) and 51.7% were male. There were no intra-operative complications. There was a significant improvement in the median OKS at six weeks (34, IQR 31.0 to 37.0), one year (38, IQR 29.0 to 43.0) and five years (37, IQR 27.0 to 42.0) when compared with the pre-operative scores (16, IQR 13.0 to 19.0) (all p = five years. The cumulative survival at five years was 98.8% and the mean survival time was 5.8 years (95% confidence interval 5.6 to 5.9). A total of seven OUKAs (2.7%) were revised; three within five years and four thereafter, between 5.1 and 5.7 years post-operatively. Five (1.9%) had re-operations within five years. The proportion of patients requiring revision at five years is lower than that generally reported for UKA. These findings add support for the use of the cementless OUKA outside the design centre. Longer follow-up is required. Cite this article: Bone Joint J 2017;99-B:623-31. ©2017 The British Editorial Society of Bone & Joint Surgery.

    AIM: To review our experience performing polypectomy in anticoagulated patients without interruption of anticoagulation.METHODS: Retrospective chart review at the Veterans Affairs Palo Alto Health Care System. Two hundred and twenty five polypectomies were performed in 123 patients. Patients followed a standardized protocol that included stopping warfarin for 36 h to avoid supratherapeutic anticoagulation from the bowel preparation. Patients with lesions larger than 1 cm were generally rescheduled for polypectomy off warfarin. Endoscopic clips were routinely applied prophylactically.RESULTS: One patient (0.8%, 95% CI: 0.1%-4.5%)developed major post-polypectomy bleeding that required transfusion. Two others (1.6%, 95% CI:0.5%-5.7%) had self-limited hematochezia at home and did not seek medical attention. The average polyp size was 5.1 ± 2.2 mm.

    Full Text Available Background : Multimodal intraoperative neuromonitoring is recommended during corrective spinal surgery, and has been widely used in surgery for spinal deformity with successful outcomes. Despite successful outcomes of corrective surgery due to increased safety of the patients with the usage of spinal cord monitoring in many large spine centers, this modality has not yet achieved widespread popularity. We report the analysis of prospectively collected intraoperative neurophysiological monitoring data of 354 consecutive patients undergoing corrective surgery for adolescent idiopathic scoliosis (AIS to establish the efficacy of multimodal neuromonitoring and to evaluate comparative sensitivity and specificity. Materials and Methods : The study group consisted of 354 (female = 309; male = 45 patients undergoing spinal deformity corrective surgery between 2004 and 2008. Patients were monitored using electrophysiological methods including somatosensory-evoked potentials and motor-evoked potentials simultaneously. Results : Mean age of patients was 13.6 years (±2.3 years. The operative procedures involved were instrumented fusion of the thoracic/lumbar/both curves, Baseline somatosensory-evoked potentials (SSEP and neurogenic motor-evoked potentials (NMEP were recorded successfully in all cases. Thirteen cases expressed significant alert to prompt reversal of intervention. All these 13 cases with significant alert had detectable NMEP alerts, whereas significant SSEP alert was detected in 8 cases. Two patients awoke with new neurological deficit (0.56% and had significant intraoperative SSEP + NMEP alerts. There were no false positives with SSEP (high specificity but 5 patients with false negatives with SSEP (38% reduced its sensitivity. There was no false negative with NMEP but 2 of 13 cases were false positive with NMEP (15%.

    PURPOSE: This study was to investigate the classification of traumatic temporomandibular joint ankylosis (TMJA) based on coronal CT sean and to present our treatment experience in the TMJ division of Shanghai Ninth People's Hospital. METHODS: From 2001 to 2009, 130 patients diagnosed of TMJA were treated in TMJ division. Among them,84 patients with 124 joints were caused by trauma and treated first by our group of surgeons. They were included in this study. All of them had CT scan, especially coronal reconstruction through the TMJ area before and after surgery. A new classification based on the coronal CT scan was proposed. The treatment protocol for Type A 1 ankylosis was fibrous tissue release or condylar head resection with costochondral graft (CCG) and temporalis myofascial flap (TMF). For Type A2 and A3 ankylosis, the lateral bony fusion was resected while the intact residual condylar fragment displaced medially was remained. The operation was named "lateral arthroplasty" (LAP). TMF or masseter muscle flap (MMF) was used as a barrier in the lateral gap between temporomandibular joint fossa and stump of the mandibular ramus, If the medial condylar fragment in Type A3 ankylosis was too small to bear the load, it was resected with the bony mass. The joint was then reconstructed with CCG and TMF or MMF. For Type A4 ankylosis, the bony fusion was completely removed and the joint was reconstructed with CCG and TMF or MMF. The result of the treatment were evaluated by CT scan and clinical follow-up. RESULTS: Among the 124 ankylotic joints, 14 were Type Al ankylosis (11.3%); 43 were Type A2 (34.7%);46 were Type A3 (37.1%) and 21 were Type A4 ankylosis (16.9%). Part of Type Al, all Type A2 and A3 ankylosis had residual condylar head displaced medially which accounted for 75% (93/124) of the TMJ ankylosis. Treatment according to the classification was: LAP for 82 joints (66.1%); CCG for 33 joints (26.6%); and other treatment for 9 joints (7.3

    To estimate the feasibility and conversion rate of laparoscopic radical hysterectomy (LRH) in early-stage cervical cancer. Data were collected from the medical records of 260 consecutive patients with stage IA2 to IIA2 cervical cancer who had undergone LRH, regardless of age, body mass index, prior abdominal surgery, uterus size, or tumor size. The median patient age was 48 years (range, 26-78 years), 11.9 % of whom were elderly (≥65 years), 11.2 % were obese (≥30 kg/m(2)), 15.4 % had undergone previous abdominal surgery, and 13.1 % had a tumor larger than 4 cm. Negative-margin resection was feasible in all patients except one. The median operative time and estimated blood loss were 253 min (range, 111-438 min) and 300 mL (range, 80-2000 mL), respectively. Intraoperative and postoperative complications occurred in seven (2.7 %) and 10 patients (3.8 %), respectively. Four patients (1.5 %) required intraoperative conversion to laparotomy, three of which were due to conglomerated metastatic lymph nodes surrounding the aorta (n = 2), the left external iliac vein (n = 1) or the left ureter (n = 1). LRH was still completed in the four conversion patients, and a laparotomy was required for the removal of the conglomerated metastatic lymph nodes and the repair of the injured vessels. The conversion rate to laparotomy among patients undergoing LRH for early-stage cervical cancer was 1.5 % when performed exclusively in consecutive patients. LRH showed comparable feasibility and effectiveness to open radical hysterectomy in the treatment of early-stage cervical cancer.

  1. Novel free-hand T1 pedicle screw method: Review of 44 consecutive cases

    Mark A Rivkin

    2014-01-01

    Full Text Available Summary of Background Data: Multilevel posterior cervical instrumented fusions are becoming more prevalent in current practice. Biomechanical characteristics of the cervicothoracic junction may necessitate extending the construct to upper thoracic segments. However, fixation in upper thoracic spine can be technically demanding owing to transitional anatomy while suboptimal placement facilitates vascular and neurologic complications. Thoracic instrumentation methods include free-hand, fluoroscopic guidance, and CT-based image guidance. However, fluoroscopy of upper thoracic spine is challenging secondary to vertebral geometry and patient positioning, while image-guided systems present substantial financial commitment and are not readily available at most centers. Additionally, imaging modalities increase radiation exposure to the patient and surgeon while potentially lengthening surgical time. Materials and Methods: Retrospective review of 44 consecutive patients undergoing a cervicothoracic fusion by a single surgeon using the novel free-hand T1 pedicle screw technique between June 2009 and November 2012. A starting point medial and cephalad to classic entry as well as new trajectory were utilized. No imaging modalities were employed during screw insertion. Postoperative CT scans were obtained on day 1. Screw accuracy was independently evaluated according to the Heary classification. Results: In total, 87 pedicle screws placed were at T1. Grade 1 placement occurred in 72 (82.8% screws, Grade 2 in 4 (4.6% screws and Grade 3 in 9 (10.3% screws. All Grade 2 and 3 breaches were <2 mm except one Grade 3 screw breaching 2-4 mm laterally. Only two screws (2.3% were noted to be Grade 4, both breaching medially by less than 2 mm. No new neurological deficits or returns to operating room took place postoperatively. Conclusions: This modification of the traditional starting point and trajectory at T1 is safe and effective. It attenuates additional bone

    2003-04-01

    This paper presents an exploratory trend analysis of the statistics published over the past twenty-four editions of the Annual Statistics of Medical School Libraries in the United States and Canada. The analysis focuses on the small subset of nineteen consistently collected data variables (out of 656 variables collected during the history of the survey) to provide a general picture of the growth and changing dimensions of services and resources provided by academic health sciences libraries over those two and one-half decades. The paper also analyzes survey response patterns for U.S. and Canadian medical school libraries, as well as osteopathic medical school libraries surveyed since 1987. The trends show steady, but not dramatic, increases in annual means for total volumes collected, expenditures for staff, collections and other operating costs, personnel numbers and salaries, interlibrary lending and borrowing, reference questions, and service hours. However, when controlled for inflation, most categories of expenditure have just managed to stay level. The exceptions have been expenditures for staff development and travel and for collections, which have both outpaced inflation. The fill rate for interlibrary lending requests has remained steady at about 75%, but the mean ratio of items lent to items borrowed has decreased by nearly 50%.

    Full Text Available This article revisits the epidemiology of dengue in Brazil, 25 years after its reemergence in the country, discussing the main determinants and implications for its control. The authors emphasize the clinical and epidemiological peculiarities of this viral disease in Brazil, which leads the world in both the number of cases reported and risk of occurrence of the disease. The article presents the changes occurring in the dengue epidemiological pattern in recent years, like the sudden age shift in the incidence of dengue hemorrhagic fever, and discusses possible associated factors. The article focuses specifically on the epidemic in Rio de Janeiro in 2008, this episode's impact on the international community, and the fear that the disease could spread to Europe. The authors conclude that the current situation emphasizes the need for the international scientific community to renew its efforts to generate knowledge allowing improvement and progress in the development of new tools and strategies for dengue prevention.Este artigo revisita a epidemiologia da dengue no Brasil após 25 anos da sua reemergência discutindo os principais determinantes e implicações no seu controle. Destacam-se peculiaridades clínicas e epidemiológicas desta virose neste país, que ocupa uma das primeiras posições no que diz respeito tanto ao número de casos notificados como no risco de ocorrência desta doença no mundo. Apresentam-se as mudanças que vêm ocorrendo no padrão epidemiológico da doença nos últimos anos, a exemplo do súbito deslocamento de faixa etária na incidência da febre hemorrágica da dengue, discutindo-se os possíveis fatores envolvidos. Particulariza-se a epidemia do Rio de Janeiro, em 2008, o reflexo deste episódio na comunidade internacional e o temor de disseminação da doença para a Europa. Os autores consideram que esta conjuntura aponta para a necessidade da comunidade científica mundial renovar esforços para gerar conhecimentos que possibilitem o aperfeiçoamento e avanço no desenvolvimento de novas ferramentas e estratégias de prevenção da dengue.

    The literature on the causes of health care reform is dominated by institutionalist accounts, and political institutions are among the most prominent factors cited to explain why change takes place. However, institutionalist accounts have difficulty explaining both the timing and the content of reforms. By applying a range of explanatory approaches to a case study of health reform in New Zealand since the 1970s, this article explores some of the theories of reform beyond institutionalism, particularly those that take into account problem pressure, policy ideas, and the more agency-centered factor of partisan ideology. The aim is not to dismiss institutionalism but to try to fill some of the gaps that cannot be addressed with institutionalist theories alone. The detailed analysis shows that various factors played a role in conjunction, namely, problem pressure, policy ideas, and the ideology of parties in government. Partisan ideology, in particular, has perhaps been prematurely ignored by health care scholars.

    Three experiments were conducted to determine the optimal true ileal digestible (TID) Trp:Lys ratio for 90- to 125-kg barrows. Basal diets contained 0.55% TID Lys and were either corn-based (Exp. 1) or corn- and soybean meal-based (Exp. 2 and 3) diets supplemented with crystalline AA. In addition, each experiment contained a corn-soybean meal control diet. The number of pigs per pen progressively increased, with pigs housed in 2 (n = 82; initial and final BW of 88.5 and 113.6 kg, respectively), 7 (n = 210, initial and final BW of 91.2 and 123.3 kg, respectively), or 20 to 22 (n = 759; initial and final BW of 98.8 and 123.4 kg, respectively) pigs per pen for each successive experiment. Pigs in Exp. 1 were fed 6 incremental additions of L-Trp, equating to TID Trp:Lys ratios of 0.109, 0.145, 0.182, 0.218, 0.255, and 0.290. For the 28-d period, there was a quadratic improvement in G:F (P = 0.05) and ADG (P = 0.08) with increasing TID Trp:Lys, characterized by an improvement in performance of pigs fed the basal diet compared with those consuming diets with a 0.145 TID Trp:Lys ratio, with a plateau thereafter as TID Trp:Lys increased. Pigs fed the control diet had less increase in backfat depth than the average of pigs fed the titration diets (1.30 vs. 4.09 mm, respectively; P = 0.02), but pork quality was unaffected by dietary treatment. Pigs in Exp. 2 were fed 4 incremental additions of L-Trp, equating to TID Trp:Lys ratios of 0.130, 0.165, 0.200, and 0.235. Average daily gain and ADFI increased in a linear fashion with increasing TID Trp:Lys for the 29-d trial (P < 0.01), with quadratic improvements in d-29 BW (P = 0.06) and G:F (P = 0.05). Pigs fed the diet containing a TID Trp:Lys ratio of 0.165 had greater d-29 BW, ADG, G:F, and lower serum urea N concentration than pigs fed the basal diet (P < 0.05), but were similar to pigs fed TID Trp:Lys ratios of 0.200 and 0.235 for all criteria measured. In Exp. 3, TID Trp:Lys ratios of 0.13, 0.15, 0.17, 0.19, and 0.21 were evaluated. The response to increasing TID Trp:Lys was limited to a quadratic (P < 0.10) improvement in G:F with increasing TID Trp:Lys ratios. Maximum G:F was noted at a TID Trp:Lys ratio of 0.17. No relationship was noted between TID Trp:Lys and carcass characteristics. These experiments demonstrate that the minimum TID Trp:Lys ratio for pigs from 90 to 125 kg of BW is at least 0.145, but not greater than 0.17.

    The World Health Organization (WHO) vaccines prequalification programme was established in 1987. It is a service provided to United Nations procurement agencies to ensure that the vaccines supplied through these agencies are consistently safe and effective under conditions of use in national immunization programmes. This review describes the purpose and aims of the programme, its evolution during 25 years of existence, its added value, and its role in the context of the WHO strategy to ensure the global availability of vaccines of assured quality. The rationale for changes introduced during the implementation of the programme is provided. The paper also discusses the resources involved, both human and financial, its performance, strengths and weaknesses and steps taken to maximize its efficiency. Th
