Background and purpose: nasopharyngeal carcinoma (NPC) represents a seldom malignancy in most developed countries. Nevertheless, NPC receives an endemic form in concrete racial entities. The aims of this study were to detect the presence of Epstein-Barr virus DNA (EBV-DNA) in peripheral blood of NPC patients, to molecularly define human leukocyte antigens (HLA) DRB1*, DQA1* and DQB1* allele frequencies, and, finally, to determine whether the genetic predisposition of an individual to NPC depends on the liability to EBV infection. Patients and methods: a total of 101 patients of Hellenic origin and nationality, with histologically proven NPC, participated in this study. EBV-DNA detection was also applied in 66 patients with EBV-related malignancies (Hodgkin's [HL] and non-Hodgkin's lymphoma [NHL]) and infectious mononucleosis (IM), as well as in 80 healthy EBV-seropositive controls. Results: 81% of the NPC patients, 77.8% with HL, 72.2% with NHL, and 66.7% with IM were EBV-DNA positive, whereas the EBV genome was detected only in 15% of the healthy controls. These differences were statistically significant in all cases. Analysis of HLA class II antigens showed decreased frequency of the DRB1*07 (p 0.003), DQA1*0103 (p = 0.002), and DQA1*0201 (p = 0.003) alleles among NPC patients. A significant association between the HLA-DR/DQ alleles and the presence of EBV-DNA in peripheral whole blood was not established. Conclusion: circulating EBV-DNA and specific HLA class II alleles may predispose to or protect from NPC. However, the results of this study suggest that the genetic predisposition of an individual to NPC is independent of the liability to EBV infection. (orig.)

Full Text Available Abstract Background Glucose variability is one of components of the dysglycemia in diabetes and may play an important role in development of diabetic vascular complications. The objective of this study was to assess the relationship between glycemic variability determined by a continuous glucose monitoring (CGM system and the presence and severity of coronary artery disease (CAD in patients with type 2 diabetes mellitus (T2DM. Methods In 344 T2DM patients with chest pain, coronary angiography revealed CAD (coronary stenosis ≥ 50% luminal diameter narrowing in 252 patients and 92 patients without CAD. Gensini score was used to assess the severity of CAD. All participants' CGM parameters and biochemical characteristics were measured at baseline. Results Diabetic patients with CAD were older, and more were male and cigarette smokers compared with the controls. Levels of the mean amplitude of glycemic excursions (MAGE (3.7 ± 1.4 mmol/L vs. 3.2 ± 1.2 mmol/L, p 1c (HbA1c, hs-CRP and total cholesterol (TC. Multivariate analysis indicated that age (p 1c (p = 0.022 and hs-CRP (p = 0.005 were independent determinants for Gensini score. Logistic regression analysis revealed that MAGE ≥ 3.4 mmol/L was an independent predictor for CAD. The area under the receiver-operating characteristic curve for MAGE (0.618, p = 0.001 was superior to that for HbA1c (0.554, p = 0.129. Conclusions The intraday glycemic variability is associated with the presence and severity of CAD in patients with T2DM. Effects of glycemic excursions on vascular complications should not be neglected in diabetes.

Full Text Available Background/Aim. The presence of aneurysmal changes on the brain blood vessels has been subject to numerous research. This study investigated the relation between ruptured aneurysms and anatomical configuration of the Circle of Willis, with the purpose to obtain an insight into their mutual connection. Methods. The analysis included 114 patients suffering from ruptured intracranial aneurysms. Preoperative cerebral angiography was performed and compared with the intraoperative findings in order to attain a precise insight into morphological changes occurring on the circle of Willis. Results. The prevalence of asymmetrical Willis in the whole group of patients was 64%. Within the group of patients suffering from multiple aneurysms, the presence of asymmetrical Willis' circle was 75.7%. The highest incidence of the asymmetrical Circle of Willis was found among patients with aneurysmal rupture detected at the anterior comunicative artery (ACoA site (72.7% among cases with solitary and 100% among those with multiple aneurysms. Morphological changes on the A1 segment of ACoA were observed in 50 (44% cases, with higher incidence found on the right side (60%. When comparing location of ruptured aneurysms between genders, a statistically significant prevalence of the ruptured aneurisms on ACoA was present in men, whereas women showed higher incidence of ruptured aneurysms on interior cartid artery (ICA site (p < 0.01. The linkage between aneurysms with hypoplasia of the A1 segment of ACA and decreasing of the angle at which segments A1 and A2 join suggests the relationship between their onset, corresponding configuration type of Willis and subsequent hemodynamic changes. Conclusion. High incidence of asymmetry of Willis circle in the group of patients with ruptured aneurysms imply association of asymmetrical configuration and disorder in haemodynamic relations with forming and rupture of intracranial aneurysms.

We investigated the effects of diabetes and the presence of lung cavities on treatment outcomes in patients with pulmonary tuberculosis. We conducted a retrospective review of the clinical records of all consecutive patients admitted to the Kanagawa Cardiovascular and Respiratory Centre with the diagnosis of pulmonary tuberculosis. The study outcomes examined were time to sputum culture conversion and percentage of patients with sputum culture conversion by the time 2 months of treatment, and these outcomes were compared between patients with and without diabetes. Of the 260 patients enrolled in the study, 69 were diagnosed as having diabetes mellitus, while the remaining 191 did not have diabetes. The percentage of patients with cavities was higher in the patients with diabetes (71.0%) than in those without (45.5%; P = 0.0003). The time to sputum culture conversion was significantly longer in the patients with diabetes than in those without (P = 0.0005), and the percentage of patients with a positive sputum culture at 2 months was higher in the patients with diabetes (43.5%) than in those without (18.8%; P = 0.0001). Multivariate analyses revealed that the presence/absence of lung cavities was a more important determinant of treatment outcomes than the presence/absence of diabetes. The presence of lung cavities was found to be a more important determinant of the treatment outcomes than that of diabetes per se in patients with pulmonary tuberculosis. © 2014 The Authors.

This paper is a report of a study to illuminate the experience of family members whose relatives survived the resuscitation in an accident and emergency department, and their preferences with regard to being present. Family presence during resuscitation can offer benefits to both patient and family members, and large healthcare organizations support and recommend offering the option for their presence. However, many staff believe that this is too distressing or traumatic for families and that they would interfere with the resuscitation process. An interpretive phenomenological approach was used to collect data in 2007-2008 with 18 family members of patients who survived life-sustaining interventions in an accident and emergency department in Hong Kong. Audio-recorded interviews were transcribed verbatim for thematic analysis and verified with the participants in second interviews. None of the family members was present in resuscitation room during the life-sustaining interventions, and five entered the room after the patients' condition was stable. The majority indicated a strong preference to be present if given the option. Three interrelated themes emerged: (i) emotional connectedness, (ii) knowing the patient, and (iii) perceived (in)appropriateness, with 10 subthemes representing affective, rational and contextual determinants of family presence preferences. The interplay of these determinants and how they contributed to strong or weak preference for family presence was analysed. Variations among the contributing determinants to each family member's preference to be present were revealed. Appropriate nursing interventions, policy and guidelines should be developed to meet individualized needs during such critical and life-threatening moments in accident and emergency departments. © 2010 Blackwell Publishing Ltd.

Aim: To determine the frequency of normal variation left atrial anatomy (NVLAA) (diverticula, accessory appendages) and normal variation pulmonary venous anatomy (NVPVA) in patients with atrial fibrillation (AF), and to determine whether the presence of these entities is associated with an increased recurrence of atrial arrhythmias following radiofrequency catheter ablation (RFCA). Materials and methods: All cardiac MDCT images performed prior to RFCA between November 2009 and May 2011 in patients with drug-refractory AF were retrospectively evaluated. The presence, type, and location of NVLAA and NVPVA, and outcome of RFCA were recorded. Success was defined as restoration of sinus rhythm. Results: Forty-six consecutive patients with a mean age of 59.8 (±9.7) years (76.1% male) underwent cardiac MDCT for anatomical planning prior to RFCA procedures. Fourteen (30.4%) patients had NVLAA, 35% of patients had NVPVA. Thirty (65%) patients had successful RFCA: 57% of these had a NVLAA, 67% had NVPVA. Sixteen (35%) patients had unsuccessful RFCA: 63% of these had a NVLAA, 56% had NVPVA. There was no significant association between the presence of NVLAA (p = 0.699), NVPVA (p = 0.197), or “NVLAA in the presence of normal pulmonary venous anatomy” (p = 0.589) and the outcome of RFCA. Conclusion: The presence of NVLAA and NVPVA appears unrelated to adverse outcome in patients undergoing RFCA for the treatment of drug-refractory AF

Leprosy is a chronic systemic infectious disease caused by Mycobacterium leprae, one of the first organisms to be established as the cause for disease in humans. Because of high prevalence pockets of leprosy in the endemic regions, it is necessary to identify the possible sources of M. leprae in the environment and its mode of transmission. Slit skin smears (SSSs) from lesions were collected in 70% ethanol from 50 leprosy cases staying in the leprosy resettlement village and hospital from a high endemic area. One hundred and sixty soil samples were collected from different areas around the leprosy hospital and from the resettlement village of cured leprosy patients where active cases also resided at the time of sample collection. M. leprae specific gene region (RLEP 129 bp) and 16S rRNA targets were used for polymerase chain reaction (PCR) based detection for the presence and viability of M. leprae. An rpoT region was also amplified to determine presence of numbers of 6 bp tandem repeats. All the SSS samples collected from patients showed three copies of rpoT region (6 bp tandem repeat, an ancient Indian type). Fifty-two soil samples showed presence of M. leprae DNA whereas M. leprae specific 16S rRNA gene was amplified in sixteen of these samples. PCR amplification and fragment length analysis showed 91 bp, i.e., three copies of the rpoT 6 bp tandem repeats from soil samples and similar three copies observed in patient samples. Presence of viable M. leprae in the soil having same rpoT genotype of M. leprae noted in patients suggests that it could be the same strain of M. leprae. M. leprae found in the soil could be the one that is excreted out by the patient. Significance of its viability in the environment and its pathogenicity with respect to transmission needs to be further explored. Findings of this study might provide possible insights for further exploration into understanding transmission patterns in leprosy and also will throw light on identifying

Helicobacter pylori infection is one of the most common bacterial infections in men. This gastrointestinal pathogen is closely related to gastritis, peptic ulcers, and the increased risk of gastric cancer. Numerous studies have indicated oral cavities as possible Helicobacter pylori reservoirs. Helicobacter pylori has been detected both in supragingival and subgingival plaques, and also in saliva. In addition, the relationship between lesions of oral mucosa and the presence of H. pylori has been evaluated and described in some studies. The aim of this study was to assess the presence of Helicobacter pylori DNA in the oral cavity of patients with oral leukoplakia and oral lichen planus. The study included 54 patients with oral leukoplakia, 72 with oral lichen planus lesions, and 40 healthy controls. The presence of Helicobacter pylori in oral cavity samples was analyzed using a single-step Polymerase Chain Reaction (PCR) method. All patients underwent a periodontal examination and the following clinical parameters were collected: pocket depth, bleeding, and plaque indexes. The periodontal status was assessed using the Offenbacher classification. In most patients, pathological lesions were in typical sites on the buccal mucosa (leukoplakia in 88%, and oral lichen planus in 93% of patients). The DNA of the Helicobacter pylori was present in 20% of patients with leukoplakia and 23% of patients with lichen planus. We did not find the DNA of H. pylori in healthy controls. The periodontal status described by periodontal indices was worse in the investigated group than in the control group. These findings suggest that the H. pylori presence in oral cavities may be related with leukoplakia and lichen planus oral lesions.

Patients with chronic bronchiectasis (BQ) may suffer from psychological disorders. The objective of this study was to assess the presence of anxiety and depression in patients from a specialised BQ Unit, using validated questionnaires. We included patients consecutively diagnosed with BQ (unrelated to cystic fibrosis) by high resolution computed tomography in the study. Patients were clinically stable in the previous three weeks and voluntarily completed the Beck Depression Inventory, State-Trait Anxiety Inventory and St. George's Respiratory Questionnaire, after signing the informed consent. They were classified according to their scores on the psychological screening questionnaires, and their results were compared with the clinical, radiological and functional parameters and Quality of Life. Seventy patients were included, 48 women and 22 men, with a mean age of 64.19years. Thirty-four percent (34%) of patients showed symptoms of depression, and around 55% had scores above the 50th percentile in trait and state anxiety. The amount of sputum was associated with trait anxiety. Bacterial colonization was related to anxiety (trait and state), especially Pseudomonas aeruginosa colonization. Female patients showed a higher risk of depression. There was no relationship between the Quality of Life scores and the established classifications of anxiety and depression. A high percentage of patients with BQ presented anxiety (trait and state) and depression. The daily sputum production and bacterial colonization (especially with P. aeruginosa) were the variables most related to anxiety; depression was more common in women. We believe that the presence of psychological disorders should be evaluated, especially in patients with this profile. Copyright © 2012 SEPAR. Published by Elsevier Espana. All rights reserved.

The aim of this study was to investigate the relationship between endocan levels with the presence of slow coronary flow (SCF). In this cross-sectional study, a total of 88 patients, who admitted to our hospital, were included in this study. Of these, 53 patients with SCF and 35 patients with normal coronary flow were included in the final analysis. Coronary flow rates of all patients were determined by the Timi Frame Count (TFC) method. In correlation analysis, endocan levels revealed a significantly positive correlation with high sensitive C-reactive protein and corrected TFC. In multivariate logistic regression analysis, the endocan levels were found as independently associated with the presence of SCF. Finally, using a cutoff level of 2.3, endocan level predicted the presence of SCF with a sensitivity of 77.2% and specificity of 75.2%. In conclusion, our study showed that higher endocan levels were significantly and independently related to the presence of SCF.

The early diagnosis of inflammatory bowel disease (IBD)-associated spondyloarthritis (SpA/IBD) in patients affected by IBD represents a major topic in clinical practice; in particular, to date there are no available serum biomarkers revealing the presence of joint inflammation in these patients. Sclerostin (SOST), an antagonist of the Wnt/β-catenin pathway, and antisclerostin-immunoglobulin G (anti-SOST-IgG) have been recently studied in patients with ankylosing spondylitis (AS) as a putative marker of disease activity. SOST and anti-SOST-IgG serum levels were assayed in 125 patients with IBD, 85 with axial or peripheral SpA, and in control groups (patients with AS and rheumatoid arthritis, and healthy individuals). The diagnostic performance in discriminating the presence of SpA/IBD was assessed for both candidate biomarkers. Patients affected by SpA/IBD with axial involvement displayed significantly lower levels of SOST and higher levels of anti-SOST-IgG compared to patients with only peripheral arthritis, IBD, and controls. Moreover, SOST and anti-SOST-IgG serum levels were inversely correlated and were associated with the duration of articular symptoms. Both biomarkers showed good accuracy in predicting the presence of axial SpA in patients with IBD. We demonstrated that in patients with IBD, SOST and anti-SOST-IgG might represent novel biomarkers to assess the presence of axial joint involvement. Moreover, the development of anti-SOST-IgG and the subsequent decrease of SOST serum levels could play a role in the pathogenesis of SpA/IBD.

The relationship between the presence of viable myocardium and the extent of coronary collateral circulation to the infarct area was evaluated in 20 patients with a recent anterior myocardial infarction who had complete obstruction of the left anterior descending coronary artery. The viability of myocardial tissue was assessed by exercise thallium-201 myocardial scintigraphy, and the collateral circulation was angiographically evaluated by means of a collateral index ranging from 0 to 3. Patients were divided into two groups according to the presence (group 1, n = 10) or absence (group 2, n = 10) of viable myocardium in the perfusion territory of the infarct-related artery. The collateral index in group 1 was 2.5 ± 0.5 (SD), which was significantly higher than the 0.7 ± 0.8 in group 2. These findings indicate that the presence of ischemic but viable myocardium is intimately related to the development of collateral circulation in patients with myocardial infarction, and the existence of well-developed collateral channels predicts the presence of viable myocardium in the infarct area

To assess the conclusiveness of Cochrane reviews in the field of gynaecological cancer. The Cochrane Library was searched for reviews regarding gynaecological cancer published between 1 January 2000 and 1 November 2014. Data were extracted from each paper and the conclusiveness of each review was assessed. The study included 66 reviews, 41 (62.1%) of which were conclusive. Of these, 58 included randomized controlled trials (RCTs), 37 (63.8%) of which were conclusive. Conclusive reviews of RCTs included significantly more patients than inconclusive reviews, but there was no difference in the number of included studies. Of the eight reviews of nonrandomized studies, four (50.0%) were conclusive. The majority of reviews recognized the need for additional studies. In the field of gynaecological cancer, reviews are more likely to be conclusive when they include RCTs, as well as large numbers of patients. © The Author(s) 2015 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.

Clinical observations show that the HIV infection is often associated with affections of the skin. In order to examine the involvement of the epidermal immune system in the HIV infection, we determined accessory cell function of epidermal cells from HIV-1-infected patients. For this we measured the proliferative response of enriched CD(4+)-T-lymphocytes from HIV-infected patients and noninfected controls to stimulation with anti-CD3 and IL-2 in the presence of epidermal cells; the enhancement of the response is dependent on the presence of functionally intact accessory cells. The capacity of epidermal cells to increase the anti-CD3-stimulated T-cell proliferative response was significantly enhanced in HIV patients (CDC III/IVA) as compared with noninfected donors. It is discussed, whether the increased activity of epidermal cells from HIV-infected patients may be responsible for several of the dermal lesions in the course of an HIV infection as due to an enhanced production and release of epidermal cell-derived cytokines.

Mitral stenosis (MS) is a common cause of atrial fibrillation (AF). Oxidative stress and inflammation factors were shown to be involved in atrial remodeling. The study aim was to compare the oxidative parameters and prolidase activity in severe MS patients with and without AF. The study population was comprised of 33 patients with MS and sinus rhythm (group I), 27 patients with MS and AF (group II), and 25 healthy controls (group III). Plasma prolidase activity, total antioxidant capacity (TAC), total oxidative status (TOS), and oxidative stress index (OSI) were determined. Additionally, we measured tissue TOS and TAC in patients with mitral valve replacement. TAC and OSI were higher, but TOS and prolidase were lower in patients with MS than control (all p 0.05). Tissue TAC was significantly lower in group II than group I (0.015 +/- 0.01 vs. 0.026 +/- 0.01 mmol Trolox equiv/L, p = 0.014), tissue TOS was similar between groups I and II (0.24 +/- 0.06 vs. 0.22 +/- 0.05 mmol Trolox equiv/L, p = 0.161). Presence of AF was correlated with systolic blood pressure, left atrial diameter, plasma TAC, tissue TAC, plasma TOS, plasma OSI, and plasma prolidase activity. Tissue TAC level (beta = -0.435, p = 0.006) and left atrial diameter (beta = 0.460, p = 0.003) were independently related with presence of AF in patients with MS. This study suggested that the presence of AF in patients with severe MS may be associated with the plasma prolidase activity, tissue and plasma oxidative parameters.

The clinical and laboratory findings in 78 patients with various forms of urolithiasis depending on the presence of primary hyperparathyroidism (PHPT) were analyzed. PHPT was diagnosed in 17 patients. Group "without PHPT" and group "with PHPT" differed significantly in terms of parathyroid hormone (PTH) level, serum calcium, phosphorus, chloride, alkaline phosphatase, calciuria and kaliuria. In patients with staghorn calculi, PHPT was diagnosed in 12.5%, and staghorn calculi in the presence of PHPT were identified in 17.7% of cases. Hypercalciuria in the group "with PHPT" was detected in 82.4% of patients (all 3 patients with staghorn calculi), and in the group "without PHPT"--in 18% of patients (2 of 21 patients with staghorn calculi). Hyperoxaluria was observed in 42.3% of patients "without PHPT" and in 35.3% of patients "with PHPT", in 36.8% of patients with simple stones and in 57.2%--with staghorn calculi. In 39% of patients "without PHPT", secondary hyperparathyroidism (SHPT) was diagnosed. SHPT prevalence was 28% in patients with staghorn calculi, and 45% in patients with simple stones. In 87.5% of patients with hypomagnesemia, staghorn calculi were observed. Significant relationship between magnesium and triglycerides (r(s) = -0.296; P = 0.041), and magnesium and high-density lipoproteins (r(s) = 0.339; P = 0.032) in all patients with urolithiasis were revealed. Thus, the study found no association between staghorn nephrolithiasis and PHPT. Elevated PTH levels usually indicate SHPT rather than PHPT. In hypocalcemia, there was more strong association between PTH and calcium, in normocalcaemia--between PTH and magnesium.

Full Text Available Abstract Introduction Autoimmune hepatitis is a necroinflammatory disorder of unknown etiology characterized by the presence of circulating antibodies, hypergammaglobulinemia, and response to immunosuppression. It has the histological features of chronic hepatitis. The onset is usually insidious, but in some patients the presentation may be acute and occasionally severe. Certain drugs can induce chronic hepatitis mimicking autoimmune hepatitis. Different autoantibodies have been associated with this process but they are not detectable after drug withdrawal and clinical resolution. Case presentation We describe a case of drug-induced acute hepatitis associated with antinuclear, antisoluble liver-pancreas and anti-smooth muscle autoantibodies in a 66-year-old woman. Abnormal clinical and biochemical parameters resolved after drug withdrawal, but six months later anti-soluble liver-pancreas antibodies remained positive and liver biopsy showed chronic hepatitis and septal fibrosis. Furthermore, our patient has a HLA genotype associated with autoimmune hepatitis. Conclusion Patient follow-up will disclose whether our patient suffers from an autoimmune disease and if the presence of anti-soluble liver antigens could precede the development of an autoimmune hepatitis, as the presence of antimitochondrial antibodies can precede primary biliary cirrhosis.

We estimated associations between neighborhood supermarket gain or loss and glycemic control (assessed by glycated hemoglobin (HbA1c) values) in patients from the Kaiser Permanente Northern California Diabetes Registry (n = 434,806 person-years; 2007-2010). Annual clinical measures were linked to metrics from a geographic information system for each patient's address of longest residence. We estimated the association between change in supermarket presence (gain, loss, or no change) and change in HbA1c value, adjusting for individual- and area-level attributes and according to baseline glycemic control (near normal, Supermarket loss was associated with worse HbA1c trajectories for those with good, moderate, and poor glycemic control at baseline, while supermarket gain was associated with marginally better HbA1c outcomes only among patients with near normal HbA1c values at baseline. Patients with the poorest baseline HbA1c values (≥9.0%) had the worst associated changes in glycemic control following either supermarket loss or gain. Differences were not clinically meaningful relative to no change in supermarket presence. For patients with type 2 diabetes mellitus, gaining neighborhood supermarket presence did not benefit glycemic control in a substantive way. The significance of supermarket changes on health depends on a complex interaction of resident, neighborhood, and store characteristics. © The Author 2017.

Papillary thyroid carcinoma (PTC) is the most common thyroid cancer. EBV is one of the most important viruses related to different types of malignancies. This study investigated the relationship between EBV and papillary thyroid carcinoma. In this study the presence of Epstein-Barr Nuclear Antigen 1 (EBNA1) gene in papillary thyroid carcinoma tissues were examined by nested-PCR method. Paraffin-embedded tissues (N=41) blocks of thyroid cancer were used. DNA was extracted from all samples and then samples were evaluated for the presence of EBV gene. In 41 samples, EBNA1 was detected in 65.8% of patients with papillary thyroid carcinoma which was significantly higher in younger ages. The significant presence of EBV genome in papillary thyroid carcinoma suggests that this virus may play a role in this cancer especially in younger ages. As a result, monitoring of patients with EBV latent infection for PTC can be very important. Copyright © 2017 Elsevier GmbH. All rights reserved.

The aim of this study was to explore the association between the presence of comorbidities and the pain experience in individual patients with temporomandibular disorder (TMD). This clinical trial comprised 112 patients with TMD pain. For all participants the presence of the following comorbid factors was assessed: pain in the neck; somatization; impaired sleep; and depression. Pain experience was evaluated using the McGill Pain Questionnaire (MPQ). For each subject the TMD-pain experience was assessed for three dimensions - sensory, affective, and evaluative - as specified in the MPQ. The association between comorbid factors and these three dimensions of TMD-pain experience was then evaluated using linear regression models. Univariable regression analyses showed that all comorbid factors, except for one factor, were positively associated with the level of pain, as rated by the sensory description of pain, the affective component of pain, and the evaluative experience of pain. The multivariable regression analyses showed that for all MPQ dimensions, depression showed the strongest associations with pain experience. It was found that in the presence of comorbid disorders, patients with TMD experience elevated levels of TMD pain. This information should be taken into consideration in the diagnostic process, as well as in the choice of treatment. © 2016 Eur J Oral Sci.

Due to sensorial autonomic neuropathy, the type and severity of angina pectoris in patients with diabetes mellitus (DM) may be rather different from the type and severity of angina pectoris in patients without DM. The aim of the study was to understand if angina pectoris is related to extensive coronary artery disease (CAD) in patients with DM. The study included 530 patients with DM who underwent coronary angiography at our center in 2009 and 2010. Patients were divided into 4 groups according to type of chest pain: group 1, noncardiac chest pain or no pain; group 2, angina equivalent; group 3, atypical angina; and group 4, typical angina. All angiograms were re-evaluated and Gensini scores were calculated. Three-vessel disease was diagnosed in the presence of stenosis >50% in all 3 coronary artery systems. There were no statistically significant differences between the groups with regard to age, sex, systolic or diastolic blood pressures, body mass index, creatinine clearance, or lipid profile. Fasting blood glucose was significantly higher in group 4 than in group 2. Gensini scores were not statistically different between groups 1 and 2 or between groups 3 and 4; however, the scores for groups 3 and 4 were higher than the score for either group 1 or group 2. Prevalence of 3-vessel disease was significantly higher in groups 3 and 4 compared with the other groups. The presence of angina pectoris was related to extensive CAD in patients with DM. The extent of CAD was not correlated with the type of angina (typical or atypical). © 2013 Wiley Periodicals, Inc.

Appropriate calcium and vitamin D intake for the prevention of osteoporosis represents an important component of osteoporosis prevention education (OPE). We sought to assess the presence and quality of OPE among osteoporotic and at-risk inpatients. Prospective chart review plus cross-sectional interview. One academic tertiary referral medical center in Rochester, Minnesota. Adults admitted to an inpatient medicine service who were determined to be at risk for osteoporosis based on an investigator-developed screening tool or previously diagnosed with osteoporosis. Four hundred sixtyfour patients were screened, 192 patients were approached for participation, and 150 patients consented to be interviewed for the study. Source of OPE, rates of appropriate calcium intake and supplementation. OPE from a health care provider was reported by 31.3% of patients, with only one patient reporting education from a pharmacist. Self OPE and no OPE were received by 29.3% and 39.3% of patients, respectively. Appropriate overall calcium intake was found in 30.7% of patients, and only 21.3% of patients were taking an appropriate calcium salt. Patients with osteoporosis and risk factors for osteoporosis lack adequate education from health care providers regarding appropriate intake of dietary and supplemental calcium and vitamin D. A particular deficit was noted in pharmacist-provided education. Specific education targeting elemental calcium amounts, salt selection, and vitamin D intake should be provided to increase the presence of appropriate overall calcium consumption.

Olfactory dysfunction in neurodegenerative conditions such as Parkinson's syndrome and Alzheimer's disease can hallmark disease onset. We hypothesized that patients with diabetes mellitus, a condition featuring peripheral and central neurodegeneration, would have decreased olfaction abilities. We examined participants with diabetic peripheral neuropathy, participants with diabetes without diabetic peripheral neuropathy, and control participants in blinded fashion using standardized Sniffin' Sticks. Diabetic peripheral neuropathy severity was quantified using the Utah Early Neuropathy Scale. Further subcategorization of diabetic peripheral neuropathy based on presence of neuropathic pain was performed with Douleur Neuropathique 4 Questionnaires. Participants with diabetes had decreased olfactory sensitivity, impaired olfactory discrimination abilities, and reduced odor identification skills when compared with controls. However, loss of olfaction ability was, at least partially, attributed to presence of neuropathic pain on subcategory assessment, although pain severity was not associated with dysfunction. Those participants with diabetes without diabetic peripheral neuropathy and those with diabetic peripheral neuropathy without neuropathic pain had similar olfactory function as controls in general. The presence of neuropathic pain, associated with limited attention and concentration, may explain at least a portion of the olfactory dysfunction witnessed in the diabetic patient population.

Objective To evaluate the feasibility of remote presence for improving the health of residents in a remote northern Inuit community. Study design A pilot study assessed patient's, nurse's and physician's satisfaction with and the use of the remote presence technology aiding delivery of health care to a remote community. A preliminary cost analysis of this technology was also performed. Methods This study deployed a remote presence RP-7 robot to the isolated Inuit community of Nain, Newfoundland and Labrador for 15 months. The RP-7 is wirelessly controlled by a laptop computer equipped with audiovisual capability and a joystick to maneuver the robot in real time to aid in the assessing and care of patients from a distant location. Qualitative data on physician's, patient's, caregiver's and staff's satisfaction were collected as well as information on its use and characteristics and the number of air transports required to the referral center and associated costs. Results A total of 252 remote presence sessions occurred during the study period, with 89% of the sessions involving direct patient assessment or monitoring. Air transport was required in only 40% of the cases that would have been otherwise transported normally. Patients and their caregivers, nurses and physicians all expressed a high level of satisfaction with the remote presence technology and deemed it beneficial for improved patient care, workloads and job satisfaction. Conclusions These results show the feasibility of deploying a remote presence robot in a distant northern community and a high degree of satisfaction with the technology. Remote presence in the Canadian North has potential for delivering a cost-effective health care solution to underserviced communities reducing the need for the transport of patients and caregivers to distant referral centers.

Full Text Available Introduction Multiple trauma is one of the leading causes of mortality and morbidity in the population of people under 45 years of age. The consequences of multiple trauma have huge epidemiological, social and economic significance. Objective The aim of the paper was to analyze the conclusive treatment outcome of multiply traumatized patients with respect to their sex, age, injury mechanism and type. METHOD This retrospective study included 100 patients with multiple injuries (ISS>16 treated in the Emergency Room of the Clinical Centre of Serbia in the course of 2004. Clinical, X-ray, laboratory and numerical presentation methods - scores (ISS and GCS were used to show the injury severity. Results Most of the injured were males (80%, and the average age was 40±20 (5-83. Out of the total number of patients who died, 23 (82% were males, and 5 (18% were females. The average age of the patients with fatal outcomes was 48±21 (8-86. Traffic accidents were the leading cause of injury (59%. The median GCS was 10±3 (3-15. The average ISS was 30 (20-66 in the surviving patients, and 53 (27-77 in those who died. Conclusion With respect to sex, in most cases multiple trauma affects males (p<0.01, with the average age of about 40. With respect to injury mechanism, the main cause of the occurrence of multiple trauma is traffic accidents (p<0.01. There is a statistically significant difference in the values of GCS and ISS relative to the definitive outcome (p<0.01. Statistical data processing indicated that there was a statistically significant correlation between mortality and type of injury in a given organic system (p<0.01, but that there was no statistically significant correlation between mortality and age. .

Images in medicine have to help the doctor in a diagnostic or therapeutic aim. The choice must be made in function of pathology or organ as known (it is not necessary to ask for a computed tomography where we know that only an echography can give the answer to the question we ask ), the criteria must stay the best performance for the cheapest price, but the quality of interpretation is a more important thing. It is important to avoid a lot of examinations which do not give better informations but are heavy to endure for the patients. In conclusion, the aim of this kind of proceedings is to assure to the patients who come confidently to us, the best service at the less constraints price without forgetting that a conclusion depends on a given methodological situation and reminding of beside machines we have not to forget the men

Helicobacter pylori (H. pylori) is the main etiologic agent of chronic gastritis and it is an important cause of gastric damage. The celiac disease can affect the morphology and the function of the gastrointestinal tract from the stomach to the colon and it is frequently associated with chronic gastritis. to assess the presence of H. pylori in gastric biopsies and in feces of pediatric patients with celiac disease and to relate it with the symptoms. Pediatric patients with celiac disease attending the Gastroenterology Service at the "Avelino Castelán" Hospital in Resistencia (Argentina) were included in the study. Gastric biopsies samples were obtained by endoscopy for histological studies, the symptoms and socio-epidemiological characteristics were recorded and the polimerase chain reaction(PCR) was applied in feces in order to detect the presence of H. pylori. Thirty one patients with celiac disease were studied (16 female and 15 male; age range:1-14 years; median 6.7 years); 14 (45.2%) were positive for H. pylori in gastric biopsy and among them, only 2 (14.2%) were positive for H. pylori in stool samples. There were not significant differences between symptoms between H. pylori positive and negative patients. 45.2% of the patients with celiac disease were infected by H. pylori. There was no correlation between the frequencies of bacterial detection in feces and in gastric biopsies. The clinical manifestations of celiac disease did not increase in children infected with H. pylori.

Subgroup classification of patientswas made as euthyroid, subclinic and clinic in Hashimato’s thyroiditis. All patients were evaluated by a single experienced ophthalmologist for the prevalence and characteristics of eye signs.RESULTS: The overall prevalences of eye changes were 22.7% (25 patients in patients and 4% (2 persons in control subjects respectively (P=0.002. In patients the most common symptom was retrobulbar eye pain with or without any eye movement. Thirteen patients had significant upper eyelid retraction (11.8%. Six patients had eye muscle dysfunction as reduced eye movements in up gaze. In control patients one person had proptosis and another had lid retraction. The clinical activity score and classification of the ophthalmopathy did not show any significant differences among subgroups.CONCLUSION:The eye signs were mostly mild (22.7% and the most common eye sign was the presence of upper eyelid retraction (11.8%. Additionally six patients had eye muscle dysfunction as reduced eye movements in up gaze. Therefore we recommend to make a routine ophthalmic examination in Hashimoto’s thyroiditis patients in order not to omit the associated ophthalmopathy.

Being present with the patient-A critical investigation of bodily sensitivity and presence in the field of physiotherapy.

Engelsrud, Gunn; Øien, Ingvil; Nordtug, Birgit

2018-04-12

This article advocates integrating ideas from phenomenological theory regarding the body with a psychoanalytical theory of language to enrich our understanding of the meaning of bodily presence in the practice of physiotherapy. The authors use this theoretical framework to explore bodily presence as a source for physiotherapists' professional development. They are using research on children as moving and meaning-producing subjects 1 1 The concept of subject is used in different ways in phenomenology and psychoanalysis, and also in varying ways in each of the two traditions. However, here the concept is used more in line with ordinary language, in the sense that it emphasizes the child's active position in her/his being in the world. to illustrate the relevance of their perspectives. They argue that the perspectives might contribute to a physiotherapeutic practice that incorporates bodily presence in the professional language in addition to specific methods and techniques. Understanding bodily presence involves the physiotherapist recognizing the Other (i.e., the patient/child) in the present moment and trusting her/his own capacity to become aware of her/his own bodily presence. The authors assert that being aware of one's own bodily presence enables therapists to develop an appreciation of their own bodies and the bodies of their patients as they are and move in mutual relation to each other. Applying the article's theoretical framework, the authors consider the body as the starting point for speech, 2 2 The concept of speech is used in a wide sense, including voice, tone, and rhythm in line with the article's psychoanalytical framework of Kristeva and the late Lacan. Thus, the call for being present for the child (as a patient) in the here and now includes participating in the speech of the child, even though the child does not use words. and suggest that introducing a richer professional language encourages practitioners to become more aware of the dialectic

Musculoskeletal findings in Sjögren's syndrome are arthralgia, arthritis, myalgia, myositis, fibromyalgia, and chronic fatigue. Enthesis zones are important in the formation of pain in the musculoskeletal system. Musculoskeletal ultrasound (US) may show subclinical enthesitis in the synovial joints and in the axial skeleton before joint swelling in inflammatory diseases characterized by arthritis. In this study, we aimed to determine the presence of enthesopathy using the Madrid sonographic enthesitis index (MASEI) in patients with primary Sjögren's syndrome (PSS). Consecutive patients with PSS and age-matched healthy controls were included in this study. All the patients met the 2002 American College of Rheumatology/European League against Rheumatism classification criteria for PSS. The demographic characteristics of the patients were recorded. Six enthesis sites were evaluated using gray-scale and Doppler US with a linear transducer, and they were scored using the MASEI. They were assessed by the EULAR Sjögren's syndrome disease activity index (ESSDAI). We evaluated 40 patients with PSS (average age 48.67 ± 11.23 years) and 30 healthy controls (average age 45.40 ± 8.24 years). Patients with PSS had significantly higher MASEI scores than the healthy controls. Plantar fascia, Achilles tendon, and distal patellar tendons were significantly thicker in the PSS group than in the healthy controls. The MASEI total score had a positive correlation with age. There was no correlation between MASEI total score and BMI and ESSDAI. In this study, it was shown that the MASEI scores assessed by US were significantly higher in patients with PSS than in healthy controls. Plantar fascia, Achilles tendon, and distal patellar tendon were significantly thicker in the PSS group than in the healthy controls. This result suggests that PSS may be one of the causes of musculoskeletal pain that can be seen in patients with PSS. Our study was the first study to use an enthesis

Purpose: The purpose of our study is to test for: (a) correlation between the presence of a perifollicular T2-hypointense rim on MRI with the presence of perifollicular hemorrhage on histology; and (b) correlation between this finding and diminished ovarian viability after intra-operative detorsion. Methods and materials: Our IRB-approved, retrospective study evaluated 780 patients between August 2012 and February 2016 with ovarian torsion as a diagnostic consideration on the emergency department note. Patients were included if they had preoperative MRI and intraoperatively confirmed case of ovarian torsion. MRIs were retrospectively reviewed for presence of perifollicular T2 hypointense rim in the torsed ovary. Two arms of analysis were performed: (a) assessment of perifollicular hemorrhage on histological exam; and (b) assessment of ovarian viability after intra-operative detorsion. Sensitivity, specificity, positive predictive value, and negative predictive value of MRI for predicting ovarian viability in the setting of torsion was performed. κ test assessed level of agreement between readers. Results: 24 patients included in one of the two arms; 20 in viability analysis and 12 in perifollicular hemorrhage analysis (8 in both). The presence of T2-hypointense rim on MRI demonstrated 88.9% sensitivity and 66.7% specificity for the diagnosis of perifollicular hemorrhage on histology, and 91.7% sensitivity and 100% specificity for predicting intraoperative viability. Conclusion: The presence of a perifollicular T2 hypointense rim on MRI in the setting of ovarian torsion correlates with perifollicular hemorrhage on histopathologic exam, and may also be a useful predictor of ovarian viability in patients presenting with ovarian torsion.

To examine the prevalence and impact of gingivitis and periodontitis in patients having heart valve surgical procedures. Nationwide Inpatient Sample for the years 2004-2010 was used. All patients who had heart valve surgical procedures were selected. Prevalence of gingivitis/periodontitis was examined in these patients. Impact of gingivitis/periodontitis on hospital charges, length of stay, and infectious complications was examined. 596,190 patients had heart valve surgical procedures. Gingivitis/periodontitis was present in 0.2 percent. Outcomes included: median hospital charges ($175,418 with gingivitis/ periodontitis versus $149,353 without gingivitis/periodontitis) and median length of stay (14 days with gingivitis/periodontitis versus 8 days without gingivitis/periodontitis). After adjusting for the effects of patient- and hospital-level confounding factors, hospital charges and length of stay were significantly higher (p gingivitis/periodontitis compared to their counterparts. Further, patients with gingivitis/periodontitis had significantly higher odds for having bacterial infections (OR = 3.41, 95% CI = 2.33-4.98, p gingivitis/periodontitis. Presence of gingivitis and periodontitis is associated with higher risk for bacterial infections and significant hospital resource utilization.

"Health" and "illness" are multilayered terms. The understanding of human health depends, apart from scientific aspects, on people's individual perceptions as well as on aspects of culture and world view. The ideal of patient-centered medicine requires that a physician does not merely have to establish an objectifiable diagnosis. Rather, a physician should also respect the patients' right to self-determination, their personal values, and their subjective view of health and illness. The philosophy of dialogue, which developed in the twentieth century, offers a conceptual background for this ideal. On an empirical basis, the successful communication between doctor and patient can be interpreted as a useful placebo phenomenon. Alternative medicine puts great emphasis on the doctor's attentive care. This also explains why the alternative branch of medicine has appealed to many patients. Therefore, science-oriented medicine should review methods in which the doctor's empathy and dialogue ability are crucial to treatment success. It is part of the physician's responsibility to appreciate the personal perspectives of patients, to respect them and, if necessary, to engage with them critically.

Artificial neural networks (ANNs) are computer programs used to identify complex relations within data. Routine predictions of presence of colorectal pathology based on population statistics have little meaning for individual patient. This results in large number of unnecessary lower gastrointestinal endoscopies (LGEs - colonoscopies and flexible sigmoidoscopies). We aimed to develop a neural network algorithm that can accurately predict presence of significant pathology in patients attending routine outpatient clinics for gastrointestinal symptoms. Ethics approval was obtained and the study was monitored according to International Committee on Harmonisation - Good Clinical Practice (ICH-GCP) standards. Three-hundred patients undergoing LGE prospectively completed a specifically developed questionnaire, which included 40 variables based on clinical symptoms, signs, past- and family history. Complete data sets of 100 patients were used to train the ANN; the remaining data was used for internal validation. The primary output used was positive finding on LGE, including polyps, cancer, diverticular disease or colitis. For external validation, the ANN was applied to data from 50 patients in primary care and also compared with the predictions of four clinicians. Clear correlation between actual data value and ANN predictions were found (r = 0.931; P = 0.0001). The predictive accuracy of ANN was 95% in training group and 90% (95% CI 84-96) in the internal validation set and this was significantly higher than the clinical accuracy (75%). ANN also showed high accuracy in the external validation group (89%). Artificial neural networks offer the possibility of personal prediction of outcome for individual patients presenting in clinics with colorectal symptoms, making it possible to make more appropriate requests for lower gastrointestinal endoscopy. © 2010 The Authors.

Purpose: The purpose of this study was to evaluate the presence of bronchiectasis in coal workers with or without coal worker pneumoconiosis (CWP) and to assess the extent of bronchiectasis, severity of bronchial wall dilatation and thickening by high resolution computed tomography (HRCT). Materials and methods: The retrospective study consisted of HRCT archives of 93 coal workers. The coal workers with previous diagnosis of COPD (six), asthma (one) and tuberculosis (three) were excluded. Five coal workers with progressive massive fibrosis were not included into the study. The resulting patient group consisted of 78 patients (43 CWP; 35 non-CWP). Pneumoconiosis profusions of CWP workers were between p0/1 and p2/2 according to ILO 1980 chest X-ray classification. HRCT examinations of all subjects were evaluated for the presence, extent, dilatation and thickness of bronchiectasis. Analysis of extent, dilatation and thickness were performed according to established criteria. Results: The diagnosis of bronchiectasis was put on 19 of 43 CWP (44.1%) and 7 of 35 non-CWP workers (20.0%). There were statistically significant differences between bronchiectasis positive and negative coal workers with CWP concerning age and exposure duration (P = 0.012 and 0.009, respectively). Then, multiple logistic regression analysis was performed to define exact risk factors. Exposure duration was only found to be related with presence of bronchiectasis [(odds ratio) OR = 1.494, 95% confidence interval 1.168-1.912]. Conclusions: The data from the present study shows that bronchiectasis is frequent and severe in CWP workers than without. Bronchiectasis is influenced by coal dust exposure. Thus, coal dust protection measures must be controlled efficiently to prevent bronchiectasis in coal workers

Assessing physician/patient relationships in the presence of HIV/AIDS: an exploratory study.

The following study investigates the nature of the relationship between physicians and HIV/AIDS patients within the context of the rapidly evolving services/relationship marketing literatures. The emerging evidence suggests that service providers generally play a critical role in the development of positive consumer attitudes and behaviors, and that relationship marketing practices can contribute to the delivery of health services. However, to date, there appears little evidence supporting the efficacy of employing relationship marketing practices in relation to a target market of HIV/AIDS patients. This exploratory study contributes to the body of knowledge by more closely investigating the nature of the patient-physician relationship relative to HIV/AIDS patients' attitudes, marketing-related behaviors, and overall quality-of-life/life satisfaction judgments. The results of this study first suggest that HIV/AIDS patients use the expectancy disconfirmation model when evaluating the performance of their physician. A reliance on expectancy disconfirmation suggests the likely prevalent role of service quality perceptions and satisfaction judgments in evaluating their relationship with their physician. Second, the results appear to support the conclusion that the patient's evaluation of their physician relationship and subsequent behaviors (e.g., word-of-mouth) are directly related to the patient's general perception of received health services. Thus, the patient/physician relationship may play a particularly powerful role in determining patient (marketing related) outcomes relative to other health service settings. Third, a direct influence is supported between negative affective reactions by patients and subsequent outcome behaviors. This finding lends support for the potential efficacy of service recovery efforts when rendering treatment to HIV/AIDS patients. Finally, evidence is presented demonstrating the effect of positive perceptions of the patient

2012-09-01

Full Text Available Abstract Background Central post-stroke pain (CPSP is a neuropathic pain syndrome associated with somatosensory abnormalities due to central nervous system lesion following a cerebrovascular insult. Post-stroke pain (PSP refers to a broader range of clinical conditions leading to pain after stroke, but not restricted to CPSP, including other types of pain such as myofascial pain syndrome (MPS, painful shoulder, lumbar and dorsal pain, complex regional pain syndrome, and spasticity-related pain. Despite its recognition as part of the general PSP diagnostic possibilities, the prevalence of MPS has never been characterized in patients with CPSP patients. We performed a cross-sectional standardized clinical and radiological evaluation of patients with definite CPSP in order to assess the presence of other non-neuropathic pain syndromes, and in particular, the role of myofascial pain syndrome in these patients. Methods CPSP patients underwent a standardized sensory and motor neurological evaluation, and were classified according to stroke mechanism, neurological deficits, presence and profile of MPS. The Visual Analogic Scale (VAS, McGill Pain Questionnaire (MPQ, and Beck Depression Scale (BDS were filled out by all participants. Results Forty CPSP patients were included. Thirty-six (90.0% had one single ischemic stroke. Pain presented during the first three months after stroke in 75.0%. Median pain intensity was 10 (5 to 10. There was no difference in pain intensity among the different lesion site groups. Neuropathic pain was continuous-ongoing in 34 (85.0% patients and intermittent in the remainder. Burning was the most common descriptor (70%. Main aggravating factors were contact to cold (62.5%. Thermo-sensory abnormalities were universal. MPS was diagnosed in 27 (67.5% patients and was more common in the supratentorial extra-thalamic group (P Conclusions The presence of MPS is not an exception after stroke and may present in association with CPSP

Full Text Available ABSTRACT Objective To determine the association of a scored patient-generated Subjective Global Assessment with mortality and length of hospital stay in cancer patients. Methods Cross-sectional study carried out between July and September 2014 using secondary data collection using data from 366 medical records of patients admitted to a hospital recognized as a cancer center of excellence. The present study included patients with hospital stay over than or equal three days and minimum age of 20 years. The patient-generated Subjective Global Assessment scores were calculated and compared with the patients’ clinical and anthropometric characteristics and outcomes (death and long length of stay in hospital. Results Of the 366 patients evaluated, 36.0% were malnourished. The presence of malnutrition, according to the scored patient-generated Subjective Global Assessment, was statistically associated with the presence of metastasis (52.4%. On the other hand, malnutrition, according to the body mass index in adults (55.8% and in older elderly patients (54.2%, was associated with death (55.0%. The adjusted logistic regression model showed that the following factors were associated with prolonged hospitalization: early nutritional screening, presence of severe malnutrition, radiotherapy and chemotherapy, and surgical procedures. As for mortality, the associated factors were: male reproductive system tumor, presence of metastasis, clinical treatment, prolonged hospitalization, and the presence of some degree of malnutrition. Conclusion The patient-generated Subjective Global Assessment score is an important risk marker of prolonged hospitalization and mortality rates. It is a useful tool capable of circumventing significant biases in the nutritional evaluation of cancer patients.

Purpose: To determine whether the electron return effect (ERE) has deleterious effects on lung SABR plans optimized in the presence of an orthogonal 1.5 T magnetic field. Methods: Data from five NSCLC-SABR patients were used. The Dose was modeled with a 2.5 mm dose grid in the presence and absence of a magnetic field using the Monaco (Elekta) TPS with the Monte Carlo GPUMCD (v5.1) algorithm. For each patient, two plans were generated, one using our conventional Elekta Agility linac beam model and another using the Elekta MRI Linac (MRL) model. Both plans were generated on the average CT using similar dose constraints and a 5 mm PTV. The optimization was performed using our clinic’s planning criteria, with normalization of the targets such that their V99% was equal to 99%. The OAR DVHs were compared for each patient. Results: The DVH plots revealed that there were limited differences when optimizing plans in the presence or absence of the magnetic field. The mean of the absolute differences, between the two planning types, in the equivalent uniform doses (EUDs) for the OARs were: 0.3 Gy (range of 0.0 - 1.0 Gy) for the esophagus, 0.6 Gy (range of 0.1 – 1.9 Gy) for the heart, 0.5 Gy (range of 0.2 – 0.8 Gy) for the lungs, and 0.6 Gy (range of 0.2 – 1.5 Gy) for the spinal canal. Regarding the maximum doses to the serial organs, the mean of the differences were 3.0 Gy (esophagus) and 0.9 Gy (spinal canal). No trends in the differences were observed. Conclusion: This study has demonstrated that there were no major differences between plans optimized using a conventional linac and those optimized using an MRI linac with an orthogonal 1.5 T magnetic field. This is attributed to the consideration of the ERE in the optimization. This project was made possible with the financial support of Elekta.

We aimed to test any association between authors' conclusions and self-reported COI or funding sources in central nervous system (CNS) studies. A review was performed for CNS malignancy clinical trials published in the last 5 years. Two investigators independently classified study conclusions according to authors' endorsement of the experimental therapy. Statistical models were used to test for associations between positive conclusions and trials characteristics. From February 2010 to February 2015, 1256 articles were retrieved; 319 were considered eligible trials. Positive conclusions were reported in 56.8% of trials with industry-only, 55.6% with academia-only, 44.1% with academia and industry, 77.8% with none, and 76.4% with not described funding source (p = 0.011). Positive conclusions were reported in 60.4% of trials with unrelated COI, 60% with related COI, and 60% with no COI reported (p = 0.997). Factors that were significantly associated with the presence of positive conclusion included trials design (phase 1) [OR 11.64 (95 CI 4.66-29.09), p source [OR 2.45 (95 CI 1.22-5.22), p = 0.011]. In a multivariable regression model, all these factors remained significantly associated with trial's positive conclusion. Funding source and self-reported COI did not appear to influence the CNS trials conclusion. Funding source information and COI disclosure were under-reported in 14.1 and 17.2% of the CNS trials. Continued efforts are needed to increase rates of both COI and funding source reporting.

Full Text Available Objective: To investigate the reactions of women with driving phobia to a therapeutic program of scheduled virtual reality exposure treatment (VRET sessions. Methods: The study intervention consisted of a computer game with car-driving scenarios that included several traffic situations. We investigated the participants’ sense of presence, subjective distress, and physiological responses during eight virtual-reality exposures. We also evaluated clinical characteristics, driving cognitions, and quality of life in the participants. Results: Thirteen women were selected. Eight were able to complete the protocol. After VRET, there was a decrease in the frequency of distorted thoughts and state anxiety scores, as well as a slight improvement in quality of life. Subjective discomfort scores, heart rate variation, and sense of presence scores confirmed that there was sense of presence in the virtual reality environment. Conclusion: All patients showed some degree of improvement and demonstrated different levels of anxiety in subsequent in vivo driving experiences. Our findings suggest that VRET could be used to facilitate in vivo exposure, because it can induce presence/immersion and reduce anxiety in patients with specific phobia. Furthermore, VRET is not associated with any type of risk.

A tendency to make hasty decisions on probabilistic reasoning tasks and a difficulty attributing mental states to others are key cognitive features of persecutory delusions (PDs) in the context of schizophrenia. This study examines whether these same psychological anomalies characterize PDs when they present in the context of psychotic depression. Performance on measures of probabilistic reasoning and theory of mind (ToM) was examined in five subgroups differing in diagnostic category and current illness status. The tendency to draw hasty decisions in probabilistic settings and poor ToM tested using story format feature in PDs irrespective of diagnosis. Furthermore, performance on the ToM story task correlated with the degree of distress caused by and preoccupation with the current PDs in the currently deluded groups. By contrast, performance on the non-verbal ToM task appears to be more sensitive to diagnosis, as patients with schizophrenia spectrum disorders perform worse on this task than those with depression irrespective of the presence of PDs. The psychological anomalies associated with PDs examined here are transdiagnostic but different measures of ToM may be more or less sensitive to indices of severity of the PDs, diagnosis and trait- or state-related cognitive effects.

We examined 929 surgically obtained thyroid glands derived from 791 female and 138 male patients and found intrathyroidal adipose tissue in 18 cases (1.94%). Only the thyroid glands of middle aged and older women (mean age 51 years) were affected, as well as in the case of follicular adenomas and nodular and diffuse hyperplasia. With respect to localization in the interstitial connective tissue, as well as between thyroid follicles, interstitial, parenchymatous and mixed types are proposed. In addition to sex and age there is a high correlation with obesity, which is suggestive of hormonal influences. Knowledge of the presence of intrathyroidal fat tissue is of interest to the pathologist since it may lead to erroneous interpretations of histological and cytological specimens of the thyroid gland. In conclusion, not one case of hypothyroidism was detected amongst the 18 cases investigated in this study.

Presence of intestinal Mycobacterium avium subspecies paratuberculosis (MAP DNA is not associated with altered MMP expression in ulcerative colitis

Full Text Available Abstract Background Mycobacterium avium subspecies paratuberculosis (MAP is suspected to be a causative agent in human Crohn's disease (CD. Recent evidence suggests that pathogenic mycobacteria and MAP can induce the expression of Matrix Metalloproteinases (MMP, which are the main proteases in the pathogenesis of mucosal ulcerations in inflammatory bowel disease (IBD. Within this study we assessed the prevalence of intestinal MAP specific DNA in patients with Crohn's disease, ulcerative colitis (UC, and healthy controls. We further analysed regulation patterns of MMPs in mucosal tissues of UC patients with and without intestinal MAP DNA detection. Methods Colonic biopsy samples were obtained from 63 Norwegian and German IBD patients and 21 healthy controls. RNA was quantified by quantitative real-time polymerase chain reaction (PCR to study MMP gene expression in both pathological and healthy mucosal specimens. The presence of MAP DNA in colonic mucosa was examined using MAP specific PCR. Results MAP DNA was detected in 20% of UC patients and 33% of healthy controls but only in 7% of patients with CD. UC patients treated with corticosteroids exhibited a significantly increased frequency of intestinal MAP DNA compared to those not receiving corticosteroids. Expression of MMP-1, -2, -7, -9, -13, -19, -28 and TNF-α did not differ between UC patients with presence of intestinal MAP DNA compared to those without. MMP-2, MMP-9 and MMP-13 were significantly decreased in UC patients receiving corticosteroids. Conclusions The presence of intestinal MAP specific DNA is not associated with altered MMP expression in UC in vivo. Corticosteroids are associated with increased detection of intestinal MAP DNA and decreased expression of certain MMPs. Frequent detection of MAP DNA in healthy controls might be attributable to the wide environmental distribution of MAP and its presence in the food-chain.

[The presence of a companion in the primary care consultation].

The presence of an adult accompanying the patient in the consulting room is a significant fact that deserves the attention of the physician. Some types of companions and their presence in the consultation have been described and may improve communication, patient management, and participatory decision making, achieving greater patient satisfaction. Consultations with companion are generally longer, and patients accompanied are often elderly, women, less educated, and with poorer physical and mental health. But it is not known exactly what is the significance of a consultation with a companion. It may be a semiological fact to keep in mind for the family diagnosis, or it may be the risks of their presence, the influence of medication, or the importance of the doctors themselves that are the cause of the presence of a companion. Different communication skills must be achieved during the interview with the companion in the consultation, rather than with the patient alone. Copyright © 2014.

Gene Profiling in Patients with Systemic Sclerosis Reveals the Presence of Oncogenic Gene Signatures

Full Text Available Systemic sclerosis (SSc is a rare connective tissue disease characterized by three pathogenetic hallmarks: vasculopathy, dysregulation of the immune system, and fibrosis. A particular feature of SSc is the increased frequency of some types of malignancies, namely breast, lung, and hematological malignancies. Moreover, SSc may also be a paraneoplastic disease, again indicating a strong link between cancer and scleroderma. The reason of this association is still unknown; therefore, we aimed at investigating whether particular genetic or epigenetic factors may play a role in promoting cancer development in patients with SSc and whether some features are shared by the two conditions. We therefore performed a gene expression profiling of peripheral blood mononuclear cells (PBMCs derived from patients with limited and diffuse SSc, showing that the various classes of genes potentially linked to the pathogenesis of SSc (such as apoptosis, endothelial cell activation, extracellular matrix remodeling, immune response, and inflammation include genes that directly participate in the development of malignancies or that are involved in pathways known to be associated with carcinogenesis. The transcriptional analysis was then complemented by a complex network analysis of modulated genes which further confirmed the presence of signaling pathways associated with carcinogenesis. Since epigenetic mechanisms, such as microRNAs (miRNAs, are believed to play a central role in the pathogenesis of SSc, we also evaluated whether specific cancer-related miRNAs could be deregulated in the serum of SSc patients. We focused our attention on miRNAs already found upregulated in SSc such as miR-21-5p, miR-92a-3p, and on miR-155-5p, miR 126-3p and miR-16-5p known to be deregulated in malignancies associated to SSc, i.e., breast, lung, and hematological malignancies. miR-21-5p, miR-92a-3p, miR-155-5p, and miR-16-5p expression was significantly higher in SSc sera compared to

To evaluate the association between aortic morphology and elasticity with aortic regurgitation in surgically corrected of tetralogy of Fallot (TOF) patients. We retrospectively identified 72 consecutive patients with surgically corrected TOF and 27 healthy controls who underwent cardiac MRI evaluation. Velocity-encoded cine MRI was used to quantify degree of aortic regurgitation (AR) in TOF patients. Ascending aorta diameters were measured at standard levels on MRA images. Aortic pulse-wave velocity (PWV) was quantified with MRI. Morphological and functional MRI variables were compared between groups of TOF patients with and without clinically relevant AR and controls. The association between aortic morphology and elasticity with the presence of AR was evaluated using univariate and multivariate logistic regression. The majority of TOF patients had only trace AR. Nine TOF patients (12 %) had an AR fraction higher than 15 %. Indexed aorta diameter at the sinotubular junction (p = 0.007), at the RPA level (p = 0.006), and low left ventricular ejection fraction (LVEF) (p = 0.015) showed the strongest associations with the presence of at least mild AR, which persisted after controlling for age and gender. Increased ascending aorta dimension is associated with AR in patients after repair of TOF. LVEF was also low in the group of patients with relevant AR compared to those without, suggesting even mild to moderate AR may contribute to LV dysfunction in these patients. Enlarged ascending aorta may be an indication for precise quantification of regurgitant fraction with MRI, since symptomatic patients may need aortic valve repair when moderate regurgitation is present.

Purpose: To evaluate the clinical value of magnetic resonance imaging (MRI) of the uterus and the pelvis in infertile female with symptomatic endometriosis for the assessment of uterine morphology and function. Materials and Methods: Forty-one infertile women (mean age: 33.2 years) with symptomatic endometriosis documented by laparoscopy were evaluated with highfield MRI (Sonata, Siemens) using T2- and T1-weighted sequences. In addition, the patients underwent hysterosalpingoscintigraphy (HSSG) for evaluation of the uterotubal transport capacity. Pathologic findings of the uterine junction zone were correlated with the laparoscopic results, clinical symptoms and uterotubal transport capacity. Results: Adenomyosis was diagnosed on T2-weighted MR-images in 35 (85.4%) patients (focal adenomatosis in 26 patients and diffuse adenomatosis in 9). Patients showing signs of adenomyosis tended to be older than patients without adenomyosis (mean age 34.1 years vs. 30.1 years) and showed a longer history of symptomatic endometriosis. A positive transport capacity in HSSG was observed in 73.1% (19/26) of the patients with focal adenomyosis and only 22.2% (2/9) of patients with diffuse adenomyosis. In 83.3% (5/6) of the patients without signs of adenomyosis, a positive uterotubal transport was documented. Conclusion: MRI of the uterus is a helpful diagnostic tool for the diagnosis of adenomyosis and for planning further therapies. Patients with the diagnosis of adenomyosis showed a reduced uterotubal transport capacity that depended on the severity of adenomyotic changes and might be a possible cause of infertility. (orig.)

Abstract Conventional stroke risk prediction tools used in atrial fibrillation (AF) incorporate the presence of diabetes mellitus (DM) as a risk factor. However, it is unknown whether this risk is homogenous or dependent on the presence of diabetic microvascular complications, such as diabetic retinopathy, nephropathy, and neuropathy. The present study examined the risk of ischemic stroke in diabetic patients with and without microvascular complications. The present study used the National Health Insurance Research Database in Taiwan with detailed healthcare data on all-comers to the Taiwanese medical system from January 1, 1996 to December 31, 2011. AF and DM were identified when listed as discharge diagnoses or confirmed more than twice in the outpatient department. Patients on antithrombotic agents were excluded. The clinical endpoint was ischemic stroke. Among the 50,180 AF patients with DM, the majority had no microvascular complications (72.7%), while 2.6% had diabetic retinopathy, 8.4% had diabetic nephropathy, and 16.1% had diabetic neuropathy. Ischemic stroke occurred in 6003 patients, with a 4.74% annual risk of ischemic stroke. When compared with DM patients without microvascular complications, those with diabetic retinopathy, nephropathy, or neuropathy had higher incidences of ischemic stroke (4.65 vs 5.07, 4.77, or 5.20 per 100 person-years, respectively). However, after adjusting for confounding factors, the differences were no longer significant. In a large nationwide AF cohort with DM, risk of ischemic stroke was similar between patients with and without microvascular complications, suggesting that risk stratification of these patients does not require inclusion of diabetic retinopathy, nephropathy, and neuropathy.

Full Text Available Background. Patients with diabetes mellitus (DM suffer comorbid depression 1.4–3 times more often than those without DM. According to the latest data, DM in the world is on the 8th place as a cause of disability in the population, while depressive disorders occupy the 4th position. Depression affects emotion, cognition, and behavior, which results in the patient’s failure to carry out adequate treatment of the disease as a consequence of decompensation. The aim of the study was to examine the relationship between cognitive status and the presence of depression in patients with adult-onset DM. Materials and methods. 81 patients with type 2 DM were examined, including 43 women and 38 men. Patients were divided into 2 groups, with and without depressive disorders. Assessment of depressive symptoms was conducted using questionnaires filled in by the patient himself, including: Centre for Epidemiologic Studies Depression Scale, Hospital Anxiety and Depression Scale. Results. According to the Centre for Epidemiologic Studies Depression Scale, the incidence of depressive disorders was 38.3 %. During examination of cognitive function, there was noted a significant decrease in performance of neuropsychological tests, namely clock drawing test and Frontal Assessment Battery (FABбы in patients with depressive disorders. In the study of the relationship of various factors, such as the duration of the disease, body mass index, systolic blood pressure, diastolic blood pressure, levels of total cholesterol, triglycerides, vibration sensitivity and the severity of depressive symptoms, no significant differences were found, while the level of glycated haemoglobin had a significant correlation with depression. Conclusions. Patients with depression had a significant decline of cognitive function according to the FAB, Mini-Mental State Examination and clock drawing test that determines the defeat of the frontal lobe of the brain. There was found

The paper presents conclusions and recommendations at the closing session of the NEA/OECD Workshop held at Fontenay-aux-Roses on 12-14 June 1995. The conclusions refer to issues like: public reaction to foodstuffs containing radioisotope concentrations under the danger standards, possible non-adherence of manufacturers, processors, distributors, et al, to the instructions and guidance from radiation protection specialists, integration of all the food chain factors in the elaboration of the emergency intervention programs, etc. Among the most significant recommendations the following may be mentioned: 1. Differences between different intervention levels and the maximum admissible levels agreed upon by national, regional or international nutrition authorities should be further studied; 2. Problems created by the Chernobyl accident (as for instance, the methods of treatment of food chain products containing unacceptable radioactivity concentrations) are still present and must be solved; 3. Further studies should be done on the socio-cultural aspects of the communication, particularly on the information in rural environment; 4. The preventive measures in agriculture should be implemented as rapidly as possible; 5. In elaborating programmes of agriculture countermeasures, the management of contaminated media, particularly, of forests and their effect on agriculture

Full Text Available BACKGROUND: Barrett's esophagus (BE is one of the most common premalignant lesions and can progress to esophageal adenocarcinoma (EA. The numerous molecular events may play a role in the neoplastic transformation of Barrett's mucosa such as the change of DNA ploidy, p53 mutation and alteration of adhesion molecules. However, the molecular mechanism of the progression of BE to EA remains unclear and most studies of mitochondrial DNA (mtDNA mutations in BE have performed on BE with the presence of dysplasia. METHODS/FINDINGS: Thus, the current study is to investigate new molecular events (Barrett's esophageal tissue-specific-mtDNA alterations/instabilities in mitochondrial genome and causative factors for their alterations using the corresponding adjacent normal mucosal tissue (NT and tissue (BT from 34 patients having Barrett's metaplasia without the presence of dysplasia. Eighteen patients (53% exhibited mtDNA mutations which were not found in adjacent NT. mtDNA copy number was about 3 times higher in BT than in adjacent NT. The activity of the mitochondrial respiratory chain enzyme complexes in tissues from Barrett's metaplasia without the presence of dysplasia was impaired. Reactive oxygen species (ROS level in BT was significantly higher than those in corresponding samples. CONCLUSION/SIGNIFICANCE: High ROS level in BT may contribute to the development of mtDNA mutations, which may play a crucial role in disease progression and tumorigenesis in BE.

Full Text Available Objective: To identify literature evidences related to actions to promote family's presence during cardiopulmonary resuscitation and invasive procedures in children hospitalized in pediatric and neonatal critical care units. Data sources : Integrative literature review in PubMed, SciELO and Lilacs databases, from 2002 to 2012, with the following inclusion criteria: research article in Medicine, or Nursing, published in Portuguese, English or Spanish, using the keywords "family", "invasive procedures", "cardiopulmonary resuscitation", "health staff", and "Pediatrics". Articles that did not refer to the presence of the family in cardiopulmonary resuscitation and invasive procedures were excluded. Therefore, 15 articles were analyzed. Data synthesis : Most articles were published in the United States (80%, in Medicine and Nursing (46%, and were surveys (72% with healthcare team members (67% as participants. From the critical analysis, four themes related to the actions to promote family's presence in invasive procedures and cardiopulmonary resuscitation were obtained: a to develop a sensitizing program for healthcare team; b to educate the healthcare team to include the family in these circumstances; c to develop a written institutional policy; d to ensure the attendance of family's needs. Conclusions: Researches on these issues must be encouraged in order to help healthcare team to modify their practice, implementing the principles of the Patient and Family Centered Care model, especially during critical episodes.

Health-related quality of life in patients with Addison's disease has been assessed in various European countries, indicating a reduced quality of life. However, no studies have addressed the impact of Addison's disease on physical activity. The aim of this study was to investigate the quality of life in Dutch patients with Addison's disease particularly regarding the presence of fatigue and the ability to be physically active. In this cross-sectional study, a postal survey was performed among Dutch patients with Addison's disease on stable glucocorticoid replacement therapy with hydrocortisone or cortisone acetate. For quality of life and physical activity assessment, patients completed general and health-related quality of life and physical activity questionnaires, and scores were compared to Dutch controls. A total of 328 patients with Addison's disease were studied. In patients with Addison's disease, only 45·7% met the standard of physical activity (Combinorm) compared to 67·8% of Dutch controls (P < 0·01). Forty-eight per cent of patients showed abnormal fatigue, while 61% had severe fatigue. The CIS fatigue scores were significantly higher compared to controls (P < 0·01). We found reduced general subjective health-related QoL scores in both male and female patients, especially in younger patients <65 years of age. Physical activity is decreased in patients with Addison's disease, combined with a reduced subjective health-related QoL and increased fatigue. © 2016 John Wiley & Sons Ltd.

Reactivation of HHVs in the CNS due to inflammation has not been well described yet. The primary aim of this study was to investigate the frequency of HHV DNA detection in the cerebrospinal fluid (CSF) of immunocompetent patients with meningoencephalitis of other than HHV origin. The secondary aim of this study was to evaluate the impact of herpesvirus co-infection on the clinical course and patient outcome. Ninety-six patients with clinically and laboratory proven tick-borne encephalitis (TBE) and 77 patients with a confirmed diagnosis of enteroviral meningitis (EVM), along with a control group of 107 patients without evidence of inflammation in the CSF were retrospectively tested by nested PCR for the presence of DNA of the neurotropic herpesviruses HSV1, HSV2, VZV, and HHV6 in the CSF. The clinical course, laboratory tests, antiviral treatment, and neurological complications in a 6-month follow-up were compared between the groups positive or negative for HHV DNA in the CSF. HHV DNA was found in the CSF of 12 (6.9%) patients (6.3% and 7.8% in the TBE and EVM groups, respectively) and in 1 (0.9%) control patient. None of the patients had recent blisters or rash. The clinical course was comparably mild in all patients. No permanent neurological sequelae were observed. Only the CSF total protein level was significantly higher in HHV DNA-positive than in HHV-negative patients. © 2015 Wiley Periodicals, Inc.

Purpose: Lobular carcinoma in situ, when found in an otherwise benign breast biopsy, is associated with an increased risk of developing a subsequent invasive breast cancer. Among patients with an infiltrating cancer resected without margin assessment, the extent of ductal carcinoma in situ is an established risk factor for LR after CS and RT. However, the association between the presence and extent of LCIS and the risk of recurrence in patients treated with CS and RT for infiltrating breast cancer remains at issue. Materials and Methods: Between 1968 and 1986, 1625 patients with clinical stage T1 and T2 invasive breast cancer were treated at the Joint Center for Radiation Therapy with complete gross tumor excision and RT to a total of ≥60 Gy. Of these, 1160 had infiltrating ductal cancer (IDC), infiltrating lobular cancer (ILC), or mixed IDC/ILC (IMC) and sufficient pathologic material for review by the study pathologists (SS and JC) to establish the presence or absence of LCIS and were evaluable at 10 years. LCIS was present adjacent to the invasive cancer in (43(1027)) IDC (4%), and either within or adjacent to the infiltrating tumor in (70(82)) ILC (85%) and (26(51)) IMC (51%). Margins were evaluable in 35% of LCIS-positive patients and 33% of LCIS-negative patients. The median follow-up time was 153 months for surviving patients. Results: The 10-year crude risk of recurrence by first site of failure for all patients was as follows: Furthermore, there was no significant relationship between the extent of the LCIS adjacent to the invasive tumor and the LR risk: The 10-year crude risk of contralateral breast cancer was 7% for the patients with LCIS and 7% for those without LCIS. CONCLUSION: We conclude that neither the presence nor the extent of LCIS is related to the risk of LR in patients with invasive breast cancer treated with CS and RT. Thus, LCIS should not be considered a contraindication to breast conservation with CS and RT

In the monograph peculiarities of radioinduced sexual dysfunctions of Chernobyl accident liquidators are described. It is shown, that ones of principal clinical manifestations of stochastic radio-genetic effects are sexual dysfunctions. Assessment in point of view of stages and components of copulative cycle is carried out. Authors made attempt to take in account all involved in sexual dysfunctions systems for examined contingent. It is noted, that genesis of radioinduced sexual dysfunctions is complex and it includes both the influence of vegetative nervous system damage and the direct damage of gonads. During clinical examination with patients it is revealed that both vegetative-vascular dysfunctions and asteno-neurotic dysfunctions are dominating. Authors noting that mentioned sexual dysfunctions are caused by low dose irradiation, and they have certain distinctions. Measures for comprehensive rehabilitation of suffered contingent in late period after irradiation are developed

Full Text Available Objective: The relationship between psychological factors and cardiac diseases has been concerned for a long but our knowledge about the cognitive profiles which could be important etiological factor in cardiac disease and comorbid psychiatric disorders is limited. In this study, we aimed to compare the cognitive profiles of coronary artery disease patients with or without comorbid anxiety disorder. Method: A total of 35 coronary artery disease patients with anxiety disorder and 20 coronary artery disease patients without comorbid anxiety disorders were enrolled into the study. Beck Anxiety Inventory and the Young Schema Questionnaire-Short Form 3 were applied to each participant. Results: Disconnection, rejection, impaired autonomy self-manifestation, extreme vigilance, unrelenting standards, other-directedness, and impaired limits schema domain scores were significantly higher in coronary artery disease patients with anxiety disorder comorbidity compared to coronary artery disease patients without anxiety disorder. Conclusion: Our study has revealed significant differences in cognitive profiles of coronary artery disease patients with comorbidity of anxiety disorders. These findings show the importance of cognitive profiles which were observed in coronary artery disease patients with anxiety disorders. Schema-focused approach might be useful in the treatment of such patients. Further studies with schema-focused therapy approaches are needed to illustrate the issue.

which two were also culture positive (Only thirty samples were cultured). The presence of H. pylori in betel chewers (with or without cancer) compared to non-betel chewers was statistically significant. (Chi-square test p < 0.05) The use of tobacco and areca nut in betel chewers was significant with the presence of H. pylori (p < 0.05). Conclusion There is a significant higher proportion of H. pylori in betel chewers compared to non-betel chewers but not between oral cancer patients compared to patients without oral cancer. Hence Betel chewing may predispose to colonisation with H. pylori in the digestive tract through swallowing the quid or during betel chewing. PMID:19772630

A fine-grained analysis of the jumping-to-conclusions bias in schizophrenia

Steffen Moritz

2009-12-01

Full Text Available Impaired decision behavior has been repeatedly observed in schizophrenia patients. We investigated several cognitive mechanisms that might contribute to the jumping-to-conclusions bias (JTC seen in schizophrenia patients: biases in information-gathering, information weighting and integration, and overconfidence, using the process tracing paradigm Mouselab. Mouselab allows for an in-depth exploration of various decision-making processes in a structured information environment. A total of 37 schizophrenia patients and 30 healthy controls participated in the experiment. Although showing less focused and systematic information search, schizophrenia patients practically considered all pieces of information and showed no JTC in the sense of collecting less pieces of evidence. Choices of patients and controls both approximated a rational solution quite well, but patients showed more extreme confidence ratings. Both groups mainly used weighted additive decision strategies for information integration and only a small proportion relied on simple heuristics. Under high stress induced by affective valence plus time pressure, however, schizophrenia patients switched to equal weighting strategies: less valid cues and more valid ones were weighted equally.

The aims of this study were to evaluate the association between the use of clinical guidelines and the use of validated screening tools, evaluate the nutritional screening policy in hospitals, and examine the association between the use of validated screening tools and the prevalence of malnutrition and nutritional interventions in hospitalized patients. This was a cross-sectional, multicenter study. Data were collected using a standardized questionnaire on three levels: institution (presence of a guideline for malnutrition), department (use of a validated screening tool), and patient (e.g., malnutrition prevalence). In all, 53 hospitals with 5255 patients participated. About 45% of the hospitals indicated that they have guidelines for malnutrition. Of the departments surveyed, 38.6% used validated screening tools as part of a standard procedure. The nutritional status of 74.5% of the patients was screened during admission, mostly on the basis of clinical observation and patient weight. A validated screening tool was used for 21.2% of the patients. Significant differences between wards with and without validated screening tools were found with regard to malnutrition prevalence (P = 0.002) and the following interventions: referral to a dietitian (P malnutrition screening tools is associated with better nutritional care and lower malnutrition prevalence rates in hospitalized patients.

This study aimed to assess the persistent presence of microorganisms on patient-derived dental impressions and gypsum casts, while highlighting important human pathogens such as Candida, methicillin-resistant Staphylococcus aureus (MRSA), and Pseudomonas aeruginosa. The practices and opinions regarding cross-infection control from 59 general dentists in Japan were obtained via a questionnaire. Alginate impressions were made from 56 patients. Using a brain heart infusion agar medium, impression and imprint cultures were carried out to visualize the microbial contamination on the surfaces of the impressions and gypsum casts, respectively. The colonies on the surfaces of the 30 impression cultures and 26 imprint cultures were collected by swabbing and then inoculated onto selective agar plates to detect streptococci, staphylococci, Candida, MRSA, and P aeruginosa. The questionnaire showed that only 54% of general dentists had a cross-infection policy in their dental clinics, and only 30% to 40% were aware of the possible persistence of MRSA or P aeruginosa on impressions and gypsum casts. The impression/imprint cultures grew a large number of visible bacterial colonies on all of impression/gypsum cast samples investigated. Selective agar cultures demonstrated the presence of streptococci (100, 100%), staphylococci (56.7, 65.4%), Candida (30, 46.2%), MRSA (26.7, 15.4%), and P aeruginosa (6.7, 7.7%) on the impressions and the gypsum casts, respectively. This investigation showed that patient-derived dental impressions and gypsum casts are contaminated with numerous microbes, including Candida, MRSA, and P aeruginosa, which are known pathogens responsible for nosocomial and/or life-threatening infection in the immunocompromised host.

Jumping to conclusions style along the continuum of delusions: delusion-prone individuals are not hastier in decision making than healthy individuals.

Directory of Open Access Journals (Sweden)

Suzanne Ho-wai So

Full Text Available Literature comparing 'jumping to conclusions' (JTC between patients and healthy controls has demonstrated the importance of the reasoning bias in the development of delusions. When groups that vary along the entire delusional continuum are included, the relationship between JTC and delusionality is less clear. This study compared JTC and delusional dimensions between 28 patients with delusions, 35 delusion-prone individuals and 32 non-delusion-prone individuals. Delusion proneness was defined by an established threshold based on the Peters et al. Delusions Inventory. Two versions of the beads task (85:15 and 60:40 were used to measure JTC. As hypothesized, patients manifested hastier data gathering than the two non-clinical groups on both beads tasks. However, delusion-prone individuals did not manifest a hastier decision making style than non-delusion prone individuals. Instead, non-delusion-prone participants showed more JTC bias than delusion-prone individuals on the easier beads task. There was no evidence for a dose-response relationship between JTC and delusional dimensions, with correlations between JTC and PDI scores found in the non-delusion-prone group only. The present finding confirms the link between an extreme JTC bias and the presence of clinical delusions, and argues against a linear relationship between JTC and delusionality along the symptomatic continuum.

Full Text Available Objectives: Previous research on the association between adjustment latitude (defined as the opportunity to adjust work efforts in case of illness and sickness absence and sickness presence has produced inconsistent results. In particular, low adjustment latitude has been identified as both a risk factor and a deterrent of sick leave. The present study uses an alternative analytical strategy with the aim of joining these results together. Material and Methods: Using a cross-sectional design, a random sample of employees covered by the Upper Austrian Sickness Fund (N = 930 was analyzed. Logistic and ordinary least square (OLS regression models were used to examine the association between adjustment latitude and days of sickness absence, sickness presence, and an estimator for the individual sickness absence and sickness presence propensity. Results: A high level of adjustment latitude was found to be associated with a reduced number of days of sickness absence and sickness presence, but an elevated propensity for sickness absence. Conclusions: Employees with high adjustment latitude experience fewer days of health complaints associated with lower rates of sick leave and sickness presence compared to those with low adjustment latitude. In case of illness, however, high adjustment latitude is associated with a higher pro­bability of taking sick leave rather than sickness presence.

Objective Mechanochemical ablation is a novel technique for ablation of varicose veins utilising a rotating catheter and liquid sclerosant. Mechanochemical ablation and radiofrequency ablation have no reported neurological side-effect but the rotating mechanism of mechanochemical ablation may produce microbubbles. Air emboli have been implicated as a cause of cerebrovascular events during ultrasound-guided foam sclerotherapy and microbubbles in the heart during ultrasound-guided foam sclerotherapy have been demonstrated. This study investigated the presence of microbubbles in the right heart during varicose vein ablation by mechanochemical abaltion and radiofrequency abaltion. Methods Patients undergoing great saphenous vein ablation by mechanochemical abaltion or radiofrequency ablation were recruited. During the ablative procedure, the presence of microbubbles was assessed using transthoracic echocardiogram. Offline blinded image quantification was performed using International Consensus Criteria grading guidelines. Results From 32 recruited patients, 28 data sets were analysed. Eleven underwent mechanochemical abaltion and 17 underwent radiofrequency abaltion. There were no neurological complications. In total, 39% (11/28) of patients had grade 1 or 2 microbubbles detected. Thirty-six percent (4/11) of mechanochemical abaltion patients and 29% (5/17) of radiofrequency ablation patients had microbubbles with no significant difference between the groups ( p=0.8065). Conclusion A comparable prevalence of microbubbles between mechanochemical abaltion and radiofrequency ablation both of which are lower than that previously reported for ultrasound-guided foam sclerotherapy suggests that mechanochemical abaltion may not confer the same risk of neurological events as ultrasound-guided foam sclerotherapy for treatment of varicose veins.

Full Text Available Introduction. A non-carious lesion (NCL is the loss of hard dental tissue on the neck, tuberculum and incisal edges of the teeth. Interest in clinical presence and in unclear etiology of these lesions allows for their future prevention and treatment. Objective. The aim of the study was to determine presence and clinical characteristics of NCLs and dentine hypersensitivity (DH, as well as their possible risk factors in children, in the population of the city of Novi Sad. Methods. A total of 55 subjects were included in the present study, aged between three and 18 years. Each subject completed a structured questionnaire related to the etiological factors, and all teeth of each subject were examined by two independent clinical dentists to determine NCLs and DH. In the case of small children, their parents or guardians filled out the questionnaire. Teeth with NCLs and DH were diagnosed according to the Basic Erosive Wear Examination (BEWE index and by a blast of air according to Schiff and Hypersensitivity Index. The review was carried out by inspection and probing. Results. The data were analyzed by clinical examination and comparison of the answers to the questionnaires. We observed an increased presence of non-caries lesions on primary teeth, compared to permanent teeth, with a statistically significant difference (χ2=3.86, df=1, p=0.04. The changes were observed in 82 teeth, and were most frequent on the canine deciduous teeth (65% and canine permanent teeth (51%. BEWE index was 10-11% to 92-100% in permanent, and 51-57% in deciduous teeth. Majority of patients with primary teeth (89.36% did not respond to air stimulus, while most patients with permanent teeth (74.29% did not react to Schiff Index. In the estimate of sensitivity, the respondents reported hypersensitivity on 6.38% of the deciduous teeth and 22.86% of the permanent teeth. Comparison of etiology factors did not reveal a direct link with the appearance of NCLs. Conclusion. Research

Madden, Eilis

2012-02-03

PURPOSE: To examine emergency nurses\\' current practices and understanding of family presence during CPR in the emergency department, Cork University Hospital, Republic of Ireland. METHOD: A quantitative descriptive design was used in the study. A questionnaire developed by ENA was distributed to emergency nurses working in a level I trauma emergency department at Cork University Hospital. The total sample number was 90, including all emergency nurses with at least 6 months\\' emergency nursing experience. RESULTS: Emergency nurses often took families to the bedside during resuscitation efforts (58.9%) or would do so if the opportunity arose (17.8%). A high percentage (74.4%) of respondents would prefer a written policy allowing the option of family presence during CPR. The most significant barrier to family witnessed resuscitation (FWR) was conflicts occurring within the emergency team. The most significant facilitator to FWR was a greater understanding of health care professionals on the benefits of FWR to patients and families, indicating the need for educational development. CONCLUSION: The findings of the study and previously published studies indicate the need for development of written polices and guidelines on the practice to meet the needs of patients, families, and staff by providing consistent, safe, and caring practices for all involved in the resuscitation process. Recommendations of the study include the development of a written policy and an educational programme on the safe implementation and practices of FWR.

Full text: The coexistence of hyperthyroidism and thyroid cancer is a rare event. The aim of this study was to evaluate the relevance of the association of hyperthyroidism and thyroid cancer. Method: From 1st January 2006 to 31st December 2006, a total of 388 new hyperthyroid patients attended the Institute of Nuclear Medicine and Ultrasound for radioiodine therapy. Eighty-two of them were selected before radioiodine therapy, on the basis of findings on palpation and ultrasound (USG) examination, to undergo fine needle aspiration cytology (FNAC) for cytological diagnosis. USG examination was performed to localize and mark the position of nodule/nodules for FNAC and, in cases of nonpalpable nodules, USG guided FNAC was done. In the case of non-nodular patients, guided FNAC was done in sonographically suspicious areas. Results: FNAC report was positive for thyroid cancer in 4 patients. Histopathology examination revealed the presence of papillary carcinoma. Among the four positive cases, one had multi-nodular goitre, two had uni-nodular goiters and one had no nodule. Another patient had a negative FNAC report but due to a huge goiter, the patient underwent surgery and histopathology revealed the presence of papillary carcinoma. Conclusion: Although the occurrence of thyroid cancer in hyperthyroid patients is rare, the presence of a nodule should be carefully evaluated to exclude the presence of concurrent malignancy. FNAC (USG guided in case of non-palpable nodules) is found helpful before radioiodine therapy or surgery. (author)

Hypertension has a significant relevance as a cardiovascular risk factor. A consistent increase on world's Metabolic Syndrome (MetS) incidence has been associated with an epidemic cardiovascular risk in different populations. Dislipidemia plays a major role determining the epidemic CV burden attributed to MetS. Apolipoprotein E (ApoE) is involved on cholesterol and triglycerides metabolism regulation. Once ApoE polymorphism may influence lipid metabolism, it is possible that it brings on individual susceptibility consequences for the development of MetS and cardiovascular risk. The objective of the study is to measure the discriminatory power of ApoE polymorphism in determining cardiovascular risk stratification based on the presence MetS in a cohort of hypertensive patients. It was enrolled 383 patients, divided in two groups, classified by MetS presence (IDF criteria): Group 1: 266 patients with MetS (MetS +) and Group 2: 117 patients without Mets (MetS -). Patient's data were collected by clinical evaluation, physical exam, file reviews and laboratory testing. Polymorphic ApoE analysis was performed by PCR amplification. Groups were compared on clinical and laboratory characteristics as well as allele and genotype distribution towards ApoE polymorphism. Mets CVD prevalence was analysed according to E4 allele prevalence. The results evidenced 184 men (48%), 63,7% whites, 45,1% diabetics and 11,7% of patients were smokers. Mean age was 64,0 ± 12,0 years. When genotypic distribution was analyzed, E3/3 genotype and E3 allele frequencies were more prevalent. Among patients with MetS, we observed an independent association between CVD prevalence and E4 allele frequency (OR 2.42 (1.17- 5.0, p < 0,05)). On the opposite direction, in those without MetS, there was lesser CVD burden in E4 allele carriers (OR 0,14 (0,02-0,75)). These associations remained significant even after confounding factor corrections. The results presented demonstrate that the association

The expansion of neuromodulation and its indications has resulted in hundreds of thousands of patients with implanted devices worldwide. Because all patients require programming, this growth has created a heavy burden on neuromodulation centers and patients. Remote point-of-care programming may provide patients with real-time access to neuromodulation expertise in their communities. To test the feasibility of remotely programming a neuromodulation device using a remote-presence robot and to determine the ability of an expert programmer to telementor a nonexpert in programming the device. A remote-presence robot (RP-7) was used for remote programming. Twenty patients were randomly assigned to either conventional programming or a robotic session. The expert remotely mentored 10 nurses with no previous experience to program the devices of patients assigned to the remote-presence sessions. Accuracy of programming, adverse events, and satisfaction scores for all participants were assessed. There was no difference in the accuracy or clinical outcomes of programming between the standard and remote-presence sessions. No adverse events occurred in any session. The patients, nurses, and the expert programmer expressed high satisfaction scores with the remote-presence sessions. This study establishes the proof-of-principle that remote programming of neuromodulation devices using telepresence and expert telementoring of an individual with no previous experience to accurately program a device is feasible. We envision a time in the future when patients with implanted devices will have real-time access to neuromodulation expertise from the comfort of their own home.

, responsibility and the home were performed. Twenty-two patients were interviewed the first time, and 15 of these were interviewed the second time. The data were analyzed in an everyday life relational perspective. RESULTS: Outpatient management facilitates time to be administrated by the patients and thereby...... the possibility of maintaining everyday life, which was essential to the patients. The privacy ensured by the home was important to patients, and they accepted the necessary responsibility that came with it. However, time spent together with fellow patients and their relatives was an important and highly valued...... part of their social life. CONCLUSIONS: Approached from the patient perspective, outpatient management provided a motivation for patients as it ensured their presence at home and provided the possibility of taking part in everyday life of the family, despite severe illness and intensive treatment...

Family presence at resuscitation attempts.

Science.gov (United States)

Jaques, Helen

UK resuscitation guidelines suggest that parents and carers should be allowed to be present during a resuscitation attempt in hospital but no guidance is available regarding family presence when resuscitation takes place out of hospital. A new research study has suggested that relatives who were offered the opportunity to witness resuscitation were less likely to develop symptoms of post-traumatic stress disorder than those who were not given the chance. This article summarises the results of this study and provides an expert commentary on its conclusions.

The incorporation of family-centered rounds has become standard in PICUs across the United States. We compared rounding times in our institution, with and without family members present, to determine the effect on total rounding time and work flow. This observational study of a convenience sample was conducted over a 17-month period (May 2014-October 2015), accounting for typical seasonal variation in the PICU. The individual patient rounding times for 2657 encounters were recorded. The presence of family members, intubation status, physician assistant participation, interruptions during rounds, attending physician's full- or part-time status, and patient census were documented. The effect of family presence on per-patient rounding time was analyzed, while controlling for influential variables. Family members were present during 1743 of 2657 (66%) rounding encounters. The average per-patient rounding time with and without family members present was 8.6 minutes and 7.3 minutes, respectively, a difference of 1.3 minutes per patient. In statistical models that accounted for other influential variables, the presence of family members was associated with a highly significant (20.4%, P family members increases per-patient rounding times in the PICU. Family presence on rounds may have benefits that outweigh the additional time required to complete each patient interaction. Copyright © 2017 by the American Academy of Pediatrics.

Full Text Available Abstract Background Although the WHO guideline for the management of dengue fever considers the presence of ascites or pleural effusions in the diagnosis of DSS, it does not emphasize the importance of their presence when selecting fluids for resuscitation. Case presentation We highlight three patients with DSS who received boluses of crystalloids on priority basis as recommended by WHO guidelines during resuscitation. All three patients had varying degrees of third space fluid loss (ascites and pleural effusions at the time of development of DSS. Ascites and pleural effusions were detected in all 3 patients at the time of shock irrespective of whether iv fluids were given or not. All three patients had documented liver involvement at the time of shock evidenced by elevation of AST (4800 iu/L, 5000 iu/L and 1960 iu/L. One patient who had profound shock died 6 hours after admission with evidence of acute pulmonary oedema in the convalescence phase. All of them needed CPAP ventilator support and potent diuretics. Conclusions We therefore feel that resuscitation of patients with DSS who already have third space fluid accumulation with crystalloid boluses on priority basis may contribute to recovery phase pulmonary oedema.

Conclusion: Ultrasound-based grading of the severity of NAFLD is associated with abnormalities in the metabolic profile of patients. The FRS is correlated with increasing severity of NAFLD based on ultrasound. These findings suggest that the presence of NAFLD may be a marker for the presence of increased cardiovascular risk and may help identify patients who may benefit from more aggressive therapies to prevent development of adverse cardiovascular events.

Rethinking presence: a grounded theory of nurses and teleconsultation.

Barrett, David

2017-10-01

To develop a theory that offered an evidence-based insight into the use of teleconsultation by nurses. Teleconsultation is the use of video to facilitate real-time, remote interaction between healthcare practitioners and patients. Although its popularity is growing, there is little understanding of how teleconsultation impacts on the role of nurses. The study adopted a constructivist grounded theory method, supplemented by the use of Straussian analytical approaches. Using selective and theoretical approaches, registered nurses with experience of using video in health care were sampled. Data were collected using semi-structured interviews exploring experiences, knowledge and feelings surrounding teleconsultation. Interviews were recorded, transcribed and subjected to three-stage, nonlinear manual analysis (open, axial and selective coding). Theoretical saturation occurred after 17 interviews. The core category identified from the data was 'nursing presence' Four subcategories of nursing presence were identified: operational, clinical, therapeutic and social. The degree to which presence could be achieved was dependent upon three influencing factors - enablers, constraints and compensation. Nurses provide different types of presence during teleconsultation, with the degree of presence dependent on specific characteristics of video-mediated communication. Where the use of video constrains the delivery of presence, nurses use a range of compensatory mechanisms to enhance patient care. Teleconsultation provides an innovative approach to enhancing the delivery of health care. This study provides nurses with insight into the impact of teleconsultation on their professional role, and an understanding of how best to use video-mediated communication to support patient care. © 2016 John Wiley & Sons Ltd.

Full Text Available Objective: To evaluate the association between exostosis and / or torus along with the variables: sex, age, ethnic aspects, anatomic site and temporomandibular joint dysfunction (TMD. Methods: This was a retrospective and serial case study. The sample consisted of 75 patients, of both genders, aged between the 1st and 10th life decades, sorted from the Center of Oral facial Pain of Pernambuco Dentistry School at the State University of Pernambuco (CDO-FOP-UPE. The data were obtained by means of patients’ interview, complemented by analyses of clinical records, besides intraoral examination for the identification, description and classification of the exostosis and/or palatal and/or mandibular torus. The descriptive statistical analyses was accomplished considering anthropometric and demographic data of the patients, applying Pearson’s chi-square test and Fisher’s exact test (p>5. Results: The torus was present in 20.0% of the cases, of which 60.0% were palatal torus. The majority of the cases occurred in male patients (25.0%, brown in color (24.3% and at the 5th decade of life (23.1%, with no association between its presence and the sex, age or race. It was observed that the displacement of the disc with reduction was the type of intra-capsular TMD most related to these alterations. Conclusion: In the studied sample, the presence of torus was registered in 20.0% of the studied subjects, although there was no statistically significant association between the presence of exostosis and the analyzed variables – sex, race and age. The displacement of the disc with reduction was the temporomandibular joint dysfunction most associated to the presence of torus.

Objective: The aim of this study was to investigate the factors which might result in normal myocardial perfusion imaging in the presence of significant coronary artery stenosis. Methods: One hundred and thirty-three patients [mean age of (59±10) years, 98 men, 35 women] who underwent coronary angiography and myocardial perfusion SPECT were retrospectively analyzed. Results: Forty-six (35%) patients performed adequate bicycle exercise testing and achieved more than 85% of their predicted maximal heart rates; while 87 (65%) patients did not. Eighty-four (63%) patients had single coronary stenosis, 31(23%) two-vessel and 17(13%) three-vessel diseases. The difference in stenosis severity among the vessels in 13 (76%) cases with three-vessel diseases was not more than 20%. There were totally 202 coronary artery stenosis: 93 (46%) in left anterior descending coronary artery (LAD), 52 (26%) left circumflex coronary artery (LCX), 52(26% ) right coronary artery (RCA) and 5 (2%) left main coronary artery (LM) disease. Eighty-six(43%) vessels had 50%-70% stenosis, 100 (49%) >70%-90% and 16(8% )more than 90%. Conclusion: Normal myocardial perfusion imaging with significant coronary artery stenosis can probably due to inadequate exercise, single vessel disease and mild to moderate stenotic lesion.

Simultaneous detection of disseminated tumor cells (DTCs) and circulating tumor cells (CTCs) was shown to be associated with an especially poor prognosis and increased incidence of disease-related deaths in non-metastatic breast cancer patients. We analyzed the occurance of DTCs and CTCs in patients with primary breast cancer and evaluated the correlation of their presence with other prognostic markers and investigated the changes in DTCs/CTCs number at different time points during treatment.Blood of 50 patients with primary breast cancer were used for immunomagnetic separation and detection of circulating tumor cells using the commercial available system the AdnaTest Breast Cancer™ (AdnaGen GmbH, Langenhagen, Germany). Bone marrow aspirates from 50 patients were analyzed for DTCs by immunocytochemistry using the pan-cytokeratin antibody conjugated with FITC (Monoclonal Anti-Cytokeratin antibody F3418, Sigma Aldrich).DTCs were identified in 30% (15/50) and CTCs in 22% (11/50) of patients. We found that DTC positivity could point to a significantly high risk of larger primary tumor size (p-value 0.011) and significantly higher risk of lymph node involvement (p-value 0.002). For CTC positivity, no such relationship was proven. DTCs have shown significantly higher prevalence in ER/PR-negative females and in HER2-positive cases. CTCs were equally prevalent in patients with the presence and absence of standard prognostic and predictive markers such as ER, PR and HER2. We found no correlation between CTCs and DTCs findings (r = -0.097, p = 0.504). We used DTCs/CTCs analysis for therapy monitoring in a small group of 29 patients, who underwent neoadjuvant chemotherapy (NACT). We find out no significant correlation between DTCs/CTCs detection and the primary tumor response to NACT. A pathologic complete response (pCR) was achieved by 31% (9/29) of the patients in our study, however, no association was observed between pCR and the detection of DTCs after NACT

Cell replacement has been explored as a therapeutic strategy to repair the brain in patients with Huntington's and Parkinson's disease. Post-mortem evaluations of healthy grafted tissue in such cases have revealed the development of Huntington- or Parkinson-like pathology including mutant huntingtin aggregates and Lewy bodies. An outstanding question remains if tau pathology can also be seen in patients with Huntington's and Parkinson's disease who had received foetal neural allografts. This was addressed by immunohistochemical/immunofluorescent stainings performed on grafted tissue of two Huntington's disease patients, who came to autopsy 9 and 12 years post-transplantation, and two patients with Parkinson's disease who came to autopsy 18 months and 16 years post-transplantation. We show that grafts also contain tau pathology in both types of transplanted patients. In two patients with Huntington's disease, the grafted tissue showed the presence of hyperphosphorylated tau [both AT8 (phospho-tau Ser202 and Thr205) and CP13 (pSer202) immunohistochemical stainings] pathological inclusions, neurofibrillary tangles and neuropil threads. In patients with Parkinson's disease, the grafted tissue was characterized by hyperphosphorylated tau (AT8; immunofluorescent staining) pathological inclusions, neurofibrillary tangles and neuropil threads but only in the patient who came to autopsy 16 years post-transplantation. Abundant tau-related pathology was observed in the cortex and striatum of all cases studied. While the striatum of the grafted Huntington's disease patient revealed an equal amount of 3-repeat and 4-repeat isoforms of tau, the grafted tissue showed elevated 4-repeat isoforms by western blot. This suggests that transplants may have acquired tau pathology from the host brain, although another possibility is that this was due to acceleration of ageing. This finding not only adds to the recent reports that tau pathology is a feature of these neurodegenerative

Full Text Available Background/Aim. In patients with premalignant cervical lesions, human papillomavirus (HPV infection, at any moment, may be spontaneously eliminated, or may persist or transform cervical epithelium from a lower to a higher degree. Due to that, it is necessary to wisely select the patients who are at high risk of cancer development. The aim of the study was to establish the interdependence between a suspicious Papanicolaou (Pap test and colposcopy with the infection caused by high-risk genotypes of human papillomavirus and the presence of premalignant cervical lesions. Methods. This prospective study used cytological, colposcopy, real-time polymerase chain reaction (PCR of high-risk genotypes of human papillomavirus and histopathological analysis of cervical biopsy specimen. Out of 2,578 female patients sent to cytological analyses in Clinical Center of Montenegro, during 2012, 2013 and 2014, the study included 80 women who had to submit their biopsy specimens due to a suspicious Pap test and atypical colposcopy results. Results. In the group of 80 (3.1%; n = 80/2,578 of the selected female patients with suspicious Pap test and colposcopy, 2/3 or 56 (70% of them had cervicitis, and 1/3 or 24 (30% had cervical intraepithelial neoplasia. The most common type in cervical intraepithelial neoplasia was HPV16 in 8 female patients, ie 61.53% out of the number of infected, or 33.33% out of the total number of premalignant lesions. Conclusion. Patients with suspicious Papanicolaou test, colposcopy results and infection which is caused by high-risk HPV infection (HPV 16 in particular often have premalignant cervical lesions. In these cases, histopathological confirmation of lesions is mandatory, since it serves as a definitive diagnostic procedure.

To investigate associations between cleft lip anthropometrics and dental anomalies in the permanent dentition in unilateral cleft lip patients. Retrospective cross-sectional study. Children with unilateral clefts of the lip, with or without cleft palate. Anthropometric lip measurements, made immediately prior to lip repair, were available for each patient. The presence of dental anomalies in the permanent dentition was assessed radiographically. The presence of associations between anthropometric lip measurements and prevalence rates of different dental anomalies were determined using logistic regression analyses. In the 122 included patients, the cleft lateral lip element was deficient in height in 80% and in transverse length in 84% of patients. Patients with more deficient cleft side lateral lip height and less deficient cleft side lateral lip transverse length were more likely to present with cleft side maxillary lateral incisor agenesis. On the other hand, patients with a less deficient cleft side lateral lip height and more deficient cleft side lateral lip transverse length were more likely to present with a cleft side supernumerary maxillary lateral incisor. When looking only at incomplete clefts, the cleft side lateral lip transverse length deficiency was more predictive of the presence of supernumerary maxillary lateral incisors (P = .030), while for complete clefts, the cleft side lateral lip height deficiency was more predictive of the presence of maxillary lateral incisor agenesis (P = .035). In patients with unilateral clefts, cleft lip anthropometrics have a predictive role in determining the occurrence of dental anomalies.

Parathyroid glands (PG) are rarely analyzed in renal transplant (RTX) patients. This study analyzes comparatively PG of RTX and end-stage renal disease (ESRD) patients. The clinical part of the study evaluates if total parathyroidectomy with autotransplantation (TPT+AT) treats appropriately hypercalcemic hyperparathyroidism in RTX patients. TPT+AT was performed in 15 of 23 RTX and 21 of 27 ESRD patients. Remaining patients underwent less-than-total PT. Volume and stage of hyperplasia were determined from 86 PG of RTX and 109 PG of ESRD patients. Patients were categorized according to the presence of small PG (volume hyperparathyroidism were evaluated 2 years after PT in RTX patients. PG of RTX patients were significantly smaller, but similar hyperplastic in comparison to PG of ESRD patients. Small PG were more frequent in RTX than in ESRD patients (19% vs 6%) and mainly graded normal or diffuse hyperplastic (94%). Forty-seven percent of RTX, but only 14% of ESRD, patients receiving a total PT possessed ≥1 small PG (P hyperparathyroidism. However, TPT+AT caused permanent hypocalcemia in 50% of RTX patients without small PG and even in 83% of RTX patients with small PG. All RTX patients receiving less-than-total PT were normocalcemic at 2-year follow-up. Logistic regression revealed a 10.7 times greater risk of permanent hypocalcemia in RTX patients with small PG receiving TPT+AT compared with RTX patients without small PG receiving TPT+AT or RTX patients undergoing less-than-total PT. Surgeons performing PT should be aware of the high frequency of small and less diseased PG in RTX patients. In this context, TPT+AT might overtreat hypercalcemic hyperparathyroidism in RTX patients, especially when small PG are present. Copyright © 2014 Mosby, Inc. All rights reserved.

Gadolinium-ethoxybenzyl-diethylenetriamine pentaacetic acid (Gd-EOB-DTPA)-enhanced magnetic resonance imaging (MRI) performed before curative therapy for hepatocellular carcinoma (HCC) can distinguish between intrahepatic distant recurrence and hypervascularization. This study aimed to retrospectively evaluate the presence of non-hypervascular hypointense nodules on hepatobiliary phase images from Gd-EOB-DTPA-enhanced MRI as a risk factor of the intrahepatic distant recurrence of early stage HCC following radiofrequency ablation (RFA). A total of 132 patients who underwent preprocedural Gd-EOB-DTPA-enhanced MRI followed by initial RFA were retrospectively analyzed. Post-RFA intrahepatic distant recurrence, which excluded the hypervascularization of non-hypervascular hypointense nodules detected by preprocedural Gd-EOB-DTPA-enhanced MRI, was evaluated according to the presence of non-hypervascular hypointense nodules on preprocedural Gd-EOB-DTPA-enhanced MRI. Intrahepatic distant recurrence rates following RFA were higher in patients with non-hypervascular hypointense nodules (1-year: 22.5%, 2-year: 52.1%, 5-year: 89.1%) compared with in patients without non-hypervascular hypointense nodules (1-year: 7.0%, 2-year: 28.8%, 5-year: 48.7%). The presence of non-hypervascular hypointense nodules was associated with markedly increased cumulative recurrence rates of both identical and different subsegment intrahepatic distant recurrence, being an independent risk factor for post-RFA identical and different subsegment intrahepatic distant recurrence (identical: HR = 2.365, P = 0.027; different: HR = 3.276, P DTPA-enhanced MRI obtained prior to RFA is an important predictive factor of intrahepatic distant recurrence following RFA of HCC. © 2016 Journal of Gastroenterology and Hepatology Foundation and John Wiley & Sons Australia, Ltd.

To characterize APC gene mutations and correlate them with patient phenotypes in individuals diagnosed with familial adenomatous polyposis (FAP) in northern Brazil. A total of 15 individuals diagnosed with FAP from 5 different families from the north of Brazil were analyzed in this study. In addition to patients with histopathological diagnosis of FAP, family members who had not developed the disease were also tested in order to identify mutations and for possible genetic counseling. All analyzed patients or their guardians signed a consent form approved by the Research Ethics Committee of the João de Barros Barreto University Hospital (Belem, Brazil). DNA extracted from the peripheral blood of a member of each of the affected families was subjected to direct sequencing. The proband of each family was sequenced to identify germline mutations using the Ion Torrent platform. To validate the detected mutations, Sanger sequencing was also performed. The samples from all patients were also tested for the identification of mutations by real-time quantitative polymerase chain reaction using the amplification refractory mutation system. Through interviews with relatives and a search of medical records, it was possible to construct genograms for three of the five families included in the study. All 15 patients from the five families with FAP exhibited mutations in the APC gene, and all mutations were detected in exon 15 of the APC gene. In addition to the patients with a histological diagnosis of FAP, family members without disease symptoms showed the mutation in the APC gene. In the present study, we detected two of the three most frequent germline mutations in the literature: the mutation at codon 1309 and the mutation at codon 1061. The presence of c.3956delC mutation was found in all families from this study, and suggests that this mutation was introduced in the population of the State of Pará through ancestor immigration (i.e., a de novo mutation that arose in one

Chemotherapy is often administered in openly designed hospital wards, where the possibility of patient-patient social influence on health exists. Previous research found that social relationships influence cancer patient's health; however, we have yet to understand social influence among patients receiving chemotherapy in the hospital. We investigate the influence of co-presence in a chemotherapy ward. We use data on 4,691 cancer patients undergoing chemotherapy in Oxfordshire, United Kingdom who average 59.8 years of age, and 44% are Male. We construct a network of patients where edges exist when patients are co-present in the ward, weighted by both patients' time in the ward. Social influence is based on total weighted co-presence with focal patients' immediate neighbors, considering neighbors' 5-year mortality. Generalized estimating equations evaluated the effect of neighbors' 5-year mortality on focal patient's 5-year mortality. Each 1,000-unit increase in weighted co-presence with a patient who dies within 5 years increases a patient's mortality odds by 42% ( β = 0.357, CI:0.204,0.510). Each 1,000-unit increase in co-presence with a patient surviving 5 years reduces a patient's odds of dying by 30% ( β = -0.344, CI:-0.538,0.149). Our results suggest that social influence occurs in chemotherapy wards, and thus may need to be considered in chemotherapy delivery.

Although computerized methods of analyzing respiratory system mechanics such as the least squares fitting method have been used in various patient populations, no conclusive data are available in patients with chronic obstructive pulmonary disease (COPD), probably because they may develop expiratory flow limitation (EFL). This suggests that respiratory mechanics be determined only during inspiration. Eight-bed multidisciplinary ICU of a teaching hospital. Eight non-flow-limited postvascular surgery patients and eight flow-limited COPD patients. Patients were sedated, paralyzed for diagnostic purposes, and ventilated in volume control ventilation with constant inspiratory flow rate. Data on resistance, compliance, and dynamic intrinsic positive end-expiratory pressure (PEEPi,dyn) obtained by applying the least squares fitting method during inspiration, expiration, and the overall breathing cycle were compared with those obtained by the traditional method (constant flow, end-inspiratory occlusion method). Our results indicate that (a) the presence of EFL markedly decreases the precision of resistance and compliance values measured by the LSF method, (b) the determination of respiratory variables during inspiration allows the calculation of respiratory mechanics in flow limited COPD patients, and (c) the LSF method is able to detect the presence of PEEPi,dyn if only inspiratory data are used.

Objective: To identify the factors that predispose to ischemic versus hemorrhagic stroke in hypertensive patients. Materials and Methods: All the hypertensive patients, who were registered in AKUH acute stroke outcome data base, over a period of 22 months, were identified and from this cohort the patients with first ever stroke were selected. The data regarding demographics, stroke type (ischemic vs. hemorrhagic), pre-existing medical problems, laboratory and radiological investigations was recorded and analyzed. Results: Five hundred and nineteen patients with either ischemic stroke or parenchymal hemorrhage were registered over a period of 22 months. Three hundred and forty-eight patients (67%) had hypertension and of these, 250 had first ever stroke at the time of admission. Presence of diabetes mellitus (OR: 3.76; Cl:1.67-8.46) and ischemic heart disease (OR: 6.97; Cl:1.57-30.98) were found to be independent predictors of ischemic strokes. Conclusion: Presence of diabetes mellitus and ischemic heart disease predict ischemic stroke in a patient with hypertension. (author)

Human metapneumovirus (hMPV), an enveloped RNA virus classified in Paramyxoviridae family, was first characterized in 2001 from children with acute respiratory tract infection. Recent studies have suggested hMPV to play a role in chronic obstructive pulmonary disease (COPD) and asthma attacks. The aims of this study were to investigate the frequency of hMPV in patients with COPD and asthma, its effects on the severity of the attacks and the relationship between demographical and clinical factors. A total of 123 patients, including 66 with COPD (45 were in attack and 21 were stable) and 57 with asthma (33 were in attack and 24 were under control) diagnosed according to the criteria of Global Initiative for Chronic Obstructive Lung Disease and the Global Strategy for Asthma Management and Prevention, respectively, were included in the study. Nasopharyngeal lavage samples collected from all of the patients have been evaluated for the presence of hMPV-RNA by using a reverse transcriptase-polymerase chain reaction (RT-PCR) targeting F gene region of the virus. hMPV-RNA positivity rates in patients with COPD and asthma were observed as 30.3% (20/66) and 31.6% (18/57), respectively, and the difference between the groups were not statistically significant (p= 1.00). When patients were compared according to their disease status, hMPV was detected in 31.1% (14/45) of patients with COPD attack and 28.6% of stable patients (p> 0.05). These rates were found as 36.4% (12/33) and 25% (6/24) in patients with asthma attack and controlled asthma, respectively (p> 0.05). Although the virus detection rates in patients with COPD and asthma attacks (26/78; 33.3%) were higher than the patients with stable/controlled disease (12/45; 26.7%), the difference was not found as statistically significant (p= 0.57). The detection rate of hMPV-RNA was 26.1% in patients who can be treated at home and hospital without any need of intensive care and mechanical ventilation, while this rate was 36

Objective: : The purpose of this study is to determine the prevalence of radiographic presence of otomastoiditis while examining temporomandibular joint (TMJ) disorders in magnetic resonance images (MRI) in a series of 2270 temporomandibular joint magnetic resonance images and to examine the relationship between otomastoiditis and TMJ disorders. Materials and methods: : 2270 temporomandibular joint magnetic resonance images and patients' data were retrospectively investigated. Magnetic resonance images were obtained from the patients who referred to Osaka University Dental Hospital Outpatient Clinic with TMJ complaints for the last four years (from January 1998 to January 2003). The patients, who were diagnosed as otomastoiditis based on their temporomandibular joint magnetic resonance images, were sent to Osaka University Hospital Department of Otolaryngology for a medical consultation in order to have their pathologies certified following their MR process. Age and sex were recorded for all patients and for otomastoiditis cases; location of the disease, symptoms of patients and TMJ findings were noted as well. Results: : Seven patients were diagnosed as acute otomastoiditis and one patient diagnosed as chronic active otitis media with cholesteatoma in the series of 2270 MR, which were representing a prevalence of 0.39%. Neurilemoma diagnosed in left mastoid process in one patient. The final diagnoses of all patients were made after medical consultation. Conclusion: : While examining temporomandibular joint magnetic resonance images; it is not only important to examine just the TMJ structures, but also to look at the nearby anatomical features to check evidence for inflammatory disease.

Full Text Available Abstract Introduction The presence of oocytes in the ovarian surface epithelium has already been confirmed in the fetal ovaries. We report the presence of SSEA-4, SOX-2, VASA and ZP2-positive primitive oocyte-like cells in the adult ovarian surface epithelium of a patient with serous papillary adenocarcinoma. Case presentation Ovarian tissue was surgically retrieved from a 67-year old patient. Histological analysis revealed serous papillary adenocarcinoma. A proportion of ovarian cortex sections was deparaffinized and immunohistochemically stained for the expression of markers of pluripotency SSEA-4 and SOX-2 and oocyte-specific markers VASA and ZP2. The analysis confirmed the presence of round, SSEA-4, SOX-2, VASA and ZP2-positive primitive oocyte-like cells in the ovarian surface epithelium. These cells were possibly related to the necrotic malignant tissue. Conclusion Primitive oocyte-like cells present in the adult ovarian surface epithelium persisting probably from the fetal period of life or developed from putative stem cells are a pathological condition which is not observed in healthy adult ovaries, and might be related to serous papillary adenocarcinoma manifestation in the adult ovarian surface epithelium. This observation needs attention to be further investigated.

Acute lymphoblastic leukemia (ALL), cancer of the white blood cells, is a heterogeneous disease that mainly occurs due to the malignant cloning of original and naive lymphocytes. The aim of this study was to explore the immunophenotype, the percentage of CD4(+)CD25(+) regulatory T cells (Tregs) and the expression of cytokines interleukin (IL)-2, IL-10 and TGF-β in patients with ALL. The immunophenotype and levels of CD4(+)CD25(+) Tregs were detected using flow cytometry in the peripheral blood of 35 ALL patients, with 18 healthy individuals being selected as controls. The results suggested that 22 patients had B cell ALL (B-ALL) and 13 had T cell ALL (T-ALL) among the 35 ALL patients. In B-ALL patients, the surface antigen CD19 was most commonly expressed; in T-ALL patients, CD7 was most common. Furthermore, the percentage of CD4(+)CD25(+) Treg cells in the peripheral blood of B-ALL and T-ALL patients was higher compared to that of healthy individuals (Pcell culture supernatants from B-ALL and T-ALL patients were higher compared to those in the controls (Pcells, IL-2, IL-10 or TGF-β in B-ALL versus T-ALL patients. The authors concluded that CD19 and CD7 may serve as diagnostic markers of B-ALL and T-ALL, respectively. The increased presence of CD4(+)CD25(+) Treg cells and the altered levels of secreted cytokines are indicative of an immunosuppressive mechanism in the pathogenesis of ALL.

The presence of gastric ectopic mucosa in Meckel's diverticulum is associated with a higher risk of development of complications. The aim of the present study was to investigate which demographic/clinical parameters predict the presence of gastric heterotopia in Meckel's diverticulum. This was a retrospective cohort study conducted in a single institution (University Hospital Ostrava, Czech republic). All children who underwent laparoscopic/open resection of Meckel's diverticulum within a 20-year study period were included in the study. In total, 88 pediatric patients underwent analysis. The mean age of the children was 4.6 ± 4.73 years; the male-female ratio was approximately 2:1. There were 50 (56.8%) patients with asymptomatic Meckel's diverticulum in our study group. Laparoscopic resection was performed in 24 (27.3%) patients; segmental bowel resection through laparotomy was performed in 13 (14.8%) patients. Gastric heterotopia was found in 39 (44.3%) patients; resection margins of all patients were clear of gastric heterotopia. No correlation was found between the presence of gastric heterotopia and the following parameters: age, gender, maternal age, prematurity, low birth weight, perinatal asphyxia, distance from Bauhin's valve and length of Meckel's diverticulum. The width of the diverticulum base was significantly higher in patients with gastric heterotopia (2.1 ± 0.57 vs. 1.2 ± 0.41 cm; p < 0.001). According to the study outcomes, the width of the diverticulum base seems to be a significant predictive factor associated with the presence of gastric heterotopia in Meckel's diverticulum. The laparoscopic/open resection of asymptomatic MD with a wide base should therefore be recommended.

Purpose: To quantify the prostate and seminal vesicles (S.V.) anatomic variations in order to choose appropriate margins including intrapelvic anatomic variations. To quantify volumetric benefit of image-guided radiotherapy (I.G.R.T.). Patients and methods: Twenty patients, receiving a total dose of 70 Gy in the prostate, had a planning CT scan and eight weekly CT scans during treatment. Prostate and S.V. were manually contoured. Each weekly CT scan was registered to the planning CT scan according to three modalities: radiopaque skin marks, pelvis bone or prostate. For each patient, prostate and S.V. displacements were quantified. 3-dimensional maps of prostate and S.V. presence probability were established. Volumes including minimal presence probabilities were compared between the three modalities of registration. Result: For the prostate intrapelvic displacements, systematic and random variations and maximal displacements for the entire population were: 5 mm, 2.7 mm and 16.5 mm in anteroposterior axis; 2.7 mm, 2.4 mm and 11.4 mm in supero-inferior axis and 0.5 mm, 0.8 mm and 3.3 mm laterally. Margins according to van Herk recipe (to cover the prostate for 90% of the patients with the 95% isodose) were: 8 mm, 8.3 mm and 1.9 mm, respectively. The 100% prostate presence probability volumes correspond to 37%, 50% and 61% according to the registration modality. For the S.V., these volumes correspond to 8%, 14% and 18% of the S.V. volume. Conclusions: Without I.G.R.T., 5 mm prostate posterior margins are insufficient and should be at least 8 mm, to account for intrapelvic anatomic variations. Prostate registration almost doubles the 100% presence probability volume compared to skin registration. Deformation of S.V. will require either to increase dramatically margins (simple) or new planning (not realistic). (authors)

Presence, Mourning, and Beauty: Elements of Analytic Process.

Markman, Henry C

2017-12-01

Analyst and patient occasionally arrive at moments of heightened meaning and aliveness. These moments can be transformative and lead to psychic change in the patient. They give life and arouse hope, and feel "real" in a new way, though often entailing emotional turbulence. Specific internal work must be done by the analyst to allow for and foster these experiences. This involves a kind of mourning process in the analyst that allows for "presence" and "availability" as described by Gabriel Marcel, and for the "at-one-ment" described by Bion. These transforming moments can be viewed in an aesthetic realm, along the lines of Keats's "Beauty is truth, truth beauty." This embodies the analytic value of emotional truth. These moments are shared and their emergence is an intersubjective creation. Clinical illustrations show how the internal work of mourning by the analyst through directed introspection allows for presence and availability, and then for shared moments of beauty with the patient.

Full Text Available Introduction. Pneumonia in patients with head trauma occurs commonly; however, few data are available to evaluate the effects of the infection on the prognosis.
Objective. The incidence and microbiological findings were described, and the associated risk factors were established with the appearance of pneumonia in patients with severe brain trauma.
Materials and methods. A prospective cohort study was conducted that included 39 patients with severe brain trauma and who required mechanical ventilation; initially, none had pneumonia. These patients were observed during a 24-month period in an attempt to discern the principal risk factors associated with the onset of pneumonia.
Results. Pneumonia occurred in 31 (80% of the 39 patients, and 28 of these presented early pneumonia. The most frequent germ in patients with pneumonia was Staphylococcus aureus with a percentage of the 42.4%. In the multivariate analysis, the single statistically significant risk factor was the presence of hypotension and vasopressor support with a RR=27.9 (95% CI=1.0-749.9, p<0.05. No significant differences in the days of mechanical ventilation or mortality in both groups. The major mortality-associated risk factor in patients with pneumonia was a low Glasgow score at admittance with an OR=2.19 (95% CI 1.03 - 4.65, p<0.05.
Conclusions. The incidence of pneumonia in patients with severe brain trauma is high; however, its appearance does not affect the prognosis. The single significant risk factor was the presence of hypotension and vasopressor support.Introducción.

Relatively little is known about the cytological characteristics of hyperfunctioning (hot) thyroid nodules. Concern has been expressed that fine-needle aspiration (FNA) identifies hot nodules as follicular tumors or indeterminate, and as a consequence patients could be unnecessarily referred for surgery. Between 1979 and 1996, thyroid FNA was performed on 829 patients. Result of thyroid scan was available in 326; 69 (21%) patients had hot, and 257 (79%) had warm or cold thyroid nodules. Nodules in each of these major groups were divided into 2 subgroups: clinically solitary nodules and dominant nodules in multinodular goiters (MNG). The frequencies of adequate versus inadequate FNA samples, and of conclusive versus indeterminate FNA results were determined separately for each of the groups and subgroups. In addition, patients with hot nodules and overt hyperthyroidism were identified and evaluated separately. Bivariate analyses were performed for the frequency of adequate versus inadequate smears and conclusive versus indeterminate results between hot, toxic, and cold-warm nodules, and between solitary nodules and MNG. The frequency of adequate aspirations and conclusive results in the various groups and subgroups was found to be statistically indistinguishable. In conclusion, the yield of adequate samples and the rate of conclusive results of FNA in thyroid nodules is similar, irrespective of the functional state or of goiter presentation. Hot thyroid nodules do not seem to produce an increase in the rate of inadequate or indeterminate FNA results, and therefore, do not affect the overall performance of thyroid FNA.

The results of the study of women in both groups indicate that the patients are moderately using coping strategies for coping with the disease, preferring the strategy of "problem resolution" and "search of social support". Patients with breast cancer "with externally visible postoperative defect in comparing with patients with breast cancer "without an externally visible postoperative defect" often use positive religious coping in coping with the disease. The group of women with «externally visible postoperative defect" usually operate with negative religious coping. Both groups of women focused on the perception of social support. In a greater degree of social support they perceive from family and significant for them. Women with breast cancer and "externally visible postoperative defect” compared with women “without an externally visible postoperative defect" are not satisfied with your opportunities, have a feeling of weakness, doubt ability to evoke respect, sympathy, understanding and approval from others. They seek to change, doubt their self-worth, willing to put themselves in the guilt of their mistakes, failures, have low self-esteem. The group of patients with breast cancer "with externally visible postoperative defect" has an external locus of control

To assess the utility of stress electrocardiography (ECG) for identifying the presence and severity of obstructive coronary artery disease (CAD) defined by coronary computed tomographic angiography (CCTA) among patients with normal nuclear myocardial perfusion imaging (MPI). The study population comprised 119 consecutive patients with normal MPI who also underwent CCTA (interval 3.5+/-3.8 months). Stress ECG was performed at the time of MPI. CCTA and MPI were interpreted using established scoring systems, and CCTA was used to define the presence and extent of CAD, which was quantified by a coronary artery jeopardy score. Within this population, 28 patients (24%) had obstructive CAD identified by CCTA. The most common CAD pattern was single-vessel CAD (61%), although proximal vessel involvement was present in 46% of patients. Patients with CAD were nearly three times more likely to have positive standard test responses (1 mm ST-segment deviation) than patients with patent coronary arteries (36 vs. 13%, P=0.007). In multivariate analysis, a positive ST-segment test response was an independent marker for CAD (odds ratio: 2.02, confidence interval: 1.09-3.78, P=0.03) even after adjustment for a composite of clinical cardiac risk factors (odds ratio: 1.85, confidence interval: 1.05-3.23, P=0.03). Despite uniformly normal MPI, mean coronary jeopardy score was three-fold higher among patients with positive compared to those with negative ST-segment response to exercise or dobutamine stress (1.9+/-2.7 vs. 0.5+/-1.4, P=0.03). Stress-induced ST-segment deviation is an independent marker for obstructive CAD among patients with normal MPI. A positive stress ECG identifies patients with a greater anatomic extent of CAD as quantified by coronary jeopardy score.

2014-10-01

Full Text Available Background: Specific pathogenic bacteria have been implicated in recurrent aphthous stomatitis (RAS, a chronic inflammatory condition characterised by ulcerations in the oral mucosa. However, the aetiology behind this condition still remains unclear. Objective: The buccal microbiota of patients with RAS was compared to that of control subjects to investigate its potential role for this condition. Design: Buccal swabs were obtained from non-ulcerative areas of 60 patients, of whom 42 patients had lesions at the time of sampling, and 60 healthy age- and gender-matched controls. Bacterial DNA was extracted and analysed by Terminal-Restriction Fragment Length Polymorphism, using enzymatic digestion of the polymerase chain reaction-amplified 16S rRNA gene, yielding a series of peaks, each representing a bacterial taxon. Results: Two peaks, 60 and 489, were more prevalent in patients with RAS than controls. Conversely, peaks 58 and 490 were less common in patients than controls. When the patients were divided into subgroups, we found that the observed differences in peak-pattern were related to the presence of lesions during sampling. Conclusions: The microbiota of the non-inflamed buccal mucosa differed between patients and controls. The differences were most pronounced in patients who presented with lesions during sampling, suggesting that a disturbance in the normal buccal microbiota triggers the presence of lesions or that presence of lesions alters the microbiota.

Results: Among the patients with goiter it was noted a high incidence of a subclinical hypothyroidism (31,58%. Thyroid autoimmunity was involved in 94,4% of the patients with clinical hypothyroidism, in 93,7 % with subclinical hypothyroidism and 100% in the patients with thyrotoxicosis. Low serum level of HDL-cholesterol was identified in 66,6% of patients with clinical hypothyroidism and 64,5% patients with subclinical hypothyroidism. The assessment of atherogenic index and coronarian risk was significantly higher (p<0,01 in patients with hypothyroidism in comparison to healthy control subjects. The incidence of vascular accidents was significantly higher (p<0,01 among the hypothyroid patients ( 19,7%/ 10,8%, of masculine gender (12,7% where the main cause of hypothyroidism was autoimmunity. Conclusions: The atherogenic index and coronarian risk were higher in patients with hypothyroidism associated to thyroid autoimmunity resulting in an increased probability in producing vascular accidents

Imputation by the mean score should be avoided when validating a Patient Reported Outcomes questionnaire by a Rasch model in presence of informative missing data

Abstract Background Nowadays, more and more clinical scales consisting in responses given by the patients to some items (Patient Reported Outcomes - PRO), are validated with models based on Item Response Theory, and more specifically, with a Rasch model. In the validation sample, presence of missing data is frequent. The aim of this paper is to compare sixteen methods for handling the missing data (mainly based on simple imputation) in the context of psychometric validation of PRO by a Rasch model. The main indexes used for validation by a Rasch model are compared. Methods A simulation study was performed allowing to consider several cases, notably the possibility for the missing values to be informative or not and the rate of missing data. Results Several imputations methods produce bias on psychometrical indexes (generally, the imputation methods artificially improve the psychometric qualities of the scale). In particular, this is the case with the method based on the Personal Mean Score (PMS) which is the most commonly used imputation method in practice. Conclusions Several imputation methods should be avoided, in particular PMS imputation. From a general point of view, it is important to use an imputation method that considers both the ability of the patient (measured for example by his\\/her score), and the difficulty of the item (measured for example by its rate of favourable responses). Another recommendation is to always consider the addition of a random process in the imputation method, because such a process allows reducing the bias. Last, the analysis realized without imputation of the missing data (available case analyses) is an interesting alternative to the simple imputation in this context.

Full Text Available Introduction: Presence of blood in the stomach has been thought to affect the performance of diagnostic tests used in detecting Helicobacter pylori (H. pylori in the stomach. This study evaluated the effect of blood on the efficacy of rapid urease test (RUT and microscopic appearance of the biopsy after staining with Giemsa stain. Materials and Methods: Patients with bleeding oesophageal varices who met the inclusion criteria were tested for H. pylori by RUT and microscopic examination of the biopsy. A repeat endoscopy, RUT and histology were done one month following initial presentation. The performance of the diagnostic tests was evaluated with and without the presence of intraluminal blood. A combined result of the two tests, RUT and histology, carried out in presence or absence of blood for the diagnosis of H. pylori, when considered together was considered as the gold standard. Results: Thirty six patients included in the study were in the ages ranging between 15-60 years (mean age = 44.14 years ±2.1. The combination of tests at both visits showed 20/36 (55.6% patients were positive for H. pylori. The decrease in H. pylori positivity in the presence of blood was significant for RUT (8.3% vs. 38.9%; P=0.005 and combined test (19.4% vs. 47.2%; P=0.02 but the decrease in positivity for histology (11.1% vs 30.6% was not significant (P=0.08. In the presence of blood, the sensitivity of RUT, histology and combined tests were 15%, 20% and 35%, respectively. In the absence of blood, the sensitivity of RUT, histology and combination of tests was 70%, 55% and 85%, respectively. Conclusion: Blood in the stomach significantly decreased the sensitivity of RUT, histology and the combination of both. Negative results of these tests in acute upper gastro intestinal (GI bleeding should therefore be interpreted carefully.

Only one simple conclusion about the climate

Findings concerning climate change, by a three-man team of scientists from the North Dakota Geological Survey, which were presented in a paper read at the Eight International Williston Basin Horizontal Well Workshop, are discussed. The survey by the three scientists covered more than 6,000 scholarly publications. It reported that while the rise in the Earth's temperature is beyond argument, there is anything but agreement as to the causes, or whether the trend is unusual enough to justify concerted and costly actions to change lifestyles. It is shown by direct instrumental measurements that the average temperature at the Earth's surface increased about 0.8 degree Celsius between 1866 and 1998. During that time the concentration of carbon dioxide in the atmosphere increased from 280 to 353 parts per million. While it is generally assumed that the global warming was caused by human activities, new techniques of measurement such as glacier ice coring, dendrochronology (tree-growth rings), lichenometry (measuring the diameter of lichens) and counting concentrations of oxygen 18 and 16 (isotopes whose presence in marine fossils varies depending on temperature) suggest that most of the global warming took place before the increase in carbon dioxide concentration occurred, raising the possibility that the increase in average temperature had causes other than the increase in greenhouse gases. Some of the studies reviewed by the group show that in Europe between ice ages during the Eemian period, some 135,000 to 110,000 years ago, temperature variations of seven degrees Celsius took place; they dropped from two degree Celsius warmer than today to five degree Celsius colder than today. Based on these findings the group's only firm conclusion was that climate is in a continual flux.

Full Text Available Introduction: The anatomical variants of the hepatic artery may have important implications for pancreatic cancer surgery. The aim of our study is to compare the outcome following a pancreatoduodenectomy (PD in patients with or without a variant hepatic artery arising from superior mesenteric artery. Material and methods: We reviewed 151 patients with periampullary tumoral pathology. All patients underwent oncological PD between January 2005 and February 2012. Our series was divided into two groups: Group A: Patients with a hepatic artery arising from superior mesenteric artery; and Group B: Patients without a hepatic artery arising from superior mesenteric artery. We expressed the results as mean ± standard deviation for continuous variables and percentages for qualitative variables. Statistical tests were considered significant if p < 0.05. Results: We identified 11 patients with a hepatic artery arising from superior mesenteric artery (7.3%. The most frequent variant was an aberrant right hepatic artery (n = 7, following by the accessory right hepatic artery (n = 2 and the common hepatic artery trunk arising from the superior mesenteric artery (n = 2. In 73% of cases the diagnosis of the variant was intraoperative. R0 resection was performed in all patients with a hepatic artery arising from superior mesenteric artery. There were no significant differences in the tumor resection margins and the incidence of postoperative complications. Conclusion: Oncological PD is feasible by the presence of a hepatic artery arising from superior mesenteric artery. The complexity of having it does not seem to influence in tumor resection margins, complications and survival.

The analysis of Proxima Centauri’s radial velocities recently led Anglada-Escudé et al. to claim the presence of a low-mass planet orbiting the Sun’s nearest star once every 11.2 days. Although the a priori probability that Proxima b transits its parent star is just 1.5%, the potential impact of such a discovery would be considerable. Independent of recent radial velocity efforts, we observed Proxima Centauri for 12.5 days in 2014 and 31 days in 2015 with the Microwave and Oscillations of Stars space telescope. We report here that we cannot make a compelling case that Proxima b transits in our precise photometric time series. Imposing an informative prior on the period and phase, we do detect a candidate signal with the expected depth. However, perturbing the phase prior across 100 evenly spaced intervals reveals one strong false positive and one weaker instance. We estimate a false-positive rate of at least a few percent and a much higher false-negative rate of 20%–40%, likely caused by the very high flare rate of Proxima Centauri. Comparing our candidate signal to HATSouth ground-based photometry reveals that the signal is somewhat, but not conclusively, disfavored (1 σ –2 σ ), leading us to argue that the signal is most likely spurious. We expect that infrared photometric follow-up could more conclusively test the existence of this candidate signal, owing to the suppression of flare activity and the impressive infrared brightness of the parent star.

Brief interventions delivered in primary health care are effective in reducing excessive drinking; online behavior-changing technique interventions may be helpful. Physicians may actively encourage the use of such interventions by helping patients access selected websites (a process known as "facilitated access"). Although the therapeutic working alliance plays a significant role in the achievement of positive outcomes in face-to-face psychotherapy and its development has been shown to be feasible online, little research has been done on its impact on brief interventions. Strengthening patients' perception of their physician's endorsement of a website could facilitate the development of an effective alliance between the patient and the app. We describe the implementation of a digitally mediated personal physician presence to enhance patient engagement with an alcohol-reduction website as part of the experimental online intervention in a noninferiority randomized controlled trial. We also report the feedback of the users on the module. The Download Your Doctor module was created to simulate the personal physician presence for an alcohol-reduction website that was developed for the EFAR-FVG trial conducted in the Italian region of Friuli-Venezia-Giulia. The module was designed to enhance therapeutic alliance and thus improve outcomes in the intervention group (facilitated access to the website). Participating general and family practitioners could customize messages and visual elements and upload a personal photo, signature, and video recordings. To assess the perceptions and attitudes of the physicians, a semistructured interview was carried out 3 months after the start of the trial. Participating patients were invited to respond to a short online questionnaire 12 months following recruitment to investigate their evaluation of their online experiences. Nearly three-quarters (23/32, 72%) of the physicians interviewed chose to customize the contents of the interaction

Family presence during resuscitation (FPDR) has advantages for the patients' family member to be present at the bedside. However, FPDR is not regularly practiced by nurses, especially in low to middle income countries. The purpose of this study was to determine Iranian nurses' and family members' attitudes towards FPDR. In a descriptive study, data was collected from the random sample of 178 nurses and 136 family members in four hospitals located in Iran. A 27-item questionnaire was used to collect data on attitudes towards FPDR, and descriptive and correlational analyses were conducted. Of family members, particularly the women, 57.2% (n=78) felt it is their right to experience FPDR and that it has many advantages for the family; including the ability to see that everything was done and worry less. However, 62.5% (n=111) of the nurses disagreed with an adult implementation of FPDR. Nurses perceived FPDR to have many disadvantages. Family members becoming distressed and interfering with the patient which may prolong the resuscitation effort. Nurses with prior education on FPDR were more willing to implement it. FPDR was desired by the majority of family members. To meet their needs, it is important to improve Iranian nurses' views about the advantages of the implementation of FPDR. Education on FPDR is recommended to improve Iranian nurses' views about the advantages of the implementation of FPDR. Copyright © 2017 Elsevier Ltd. All rights reserved.

Total Knee Arthroplasty for Knee Osteoarthritis: Support for a Foregone Conclusion?

Steinhaus, Michael E; Christ, Alexander B; Cross, Michael B

2017-07-01

Total knee arthroplasty (TKA) is generally accepted as the definitive treatment for advanced knee arthritis after patients fail nonoperative treatments; however, the safety and efficacy of TKA compared to continued nonoperative treatment has never been proven in high-quality, randomized controlled trials. Recently, a 2015 Danish study published a 12-month follow-up on a cohort of patients randomized to either a TKA or continued nonsurgical management for advanced knee osteoarthritis (OA). The authors reported significantly greater improvement in the TKA group in functional outcome scores such as the overall Knee Injury and Osteoarthritis Outcome Score (KOOS 4 score), the KOOS subscales, EQ-5D descriptive index, and timed get up-and-go and 20-m walk tests; however, patients in the TKA did suffer significantly more serious adverse events (SAE). The authors concluded that TKA combined with additional nonoperative care postoperatively is more efficacious than nonsurgical treatment alone in terms of improving pain, function, and quality of life at 12 months but is associated with more SAE. The purpose of this review is to identify the strengths and weaknesses of this trial, interpret its outcomes within the context of prior literature, and evaluate the validity of its conclusions.

Full Text Available Increased multidrug resistance of extended-spectrum beta-lactamases (ESBLs compromises the efficacy of treatment of urinary tract infections. The objective of this study is to determine the prevalence of ESBL-producing uropathogens from patients with chronic pyelonephritis (CP and to evaluate the risk factors of these types of infections. Screening for the presence of plasmid-mediated ESBL was performed by polymerase chain reaction. Out of 105 patients, 22 (20.9% revealed strains with resistance genes: 11 (36.7%, 11 (36.7% and 8 (26.7% were identified to carry bla(TEM, bla(SHV and bla(CTX-M beta-lactamase genes, respectively. We have demonstrated that prevalence of the resistance among patients with CP combined with type 2 DM was 31.3%, while among patients with CP without type 2 DM was 27.4%; however the difference between these groups was not significant. The main factors related with appearance of plasmid-mediated resistance genes were age range above 55 years, Chronic Kidney Disease stage ІІІ and ІV, in-patient treatment history, history of using antibiotics last year. Isolation and detection of ESBL-producing strains are essential fоr the sеlection оf the mоst effеctive antibiоtic for the empiric trеatment.

Presence and enactment as a vehicle of psychotherapeutic change.

1999-01-01

This article addresses an aspect of psychoanalytic and psychotherapeutic process that leads to change. Focusing on an aspect of the patient-therapist interaction that the author calls "presence" of the therapist, it demonstrates how the experience of this may lead the patient to unconscious enactment of early wishful fantasies concerning the good parent. The gratification of these wishes implicit in the interaction influences the therapist-patient relationship and plays a significant role in change.

Acute respiratory distress syndrome (ARDS) is today a leading cause of hospitalization in intensive care unit (ICU). ARDS and pneumonia are closely related to critically ill patients; however, the etiologic agent is not always identified. The presence of human herpes simplex virus 1, human cytomegalovirus and Epstein-Barr virus in respiratory samples of critically ill patients is increasingly reported even without canonical immunosuppression. The main aim of this study was to better understand the significance of herpesviruses finding in lower respiratory tract of ARDS patients hospitalized in ICU. The presence of this group of herpesviruses, in addition to the research of influenza viruses and other common respiratory viruses, was investigated in respiratory samples from 54 patients hospitalized in ICU, without a known microbiological causative agent. Moreover, the immunophenotype of each patient was analyzed. Herpesviruses DNA presence in the lower respiratory tract seemed not attributable to an impaired immunophenotype, whereas a significant correlation was observed between herpesviruses positivity and influenza virus infection. A higher ICU mortality was significantly related to the presence of herpesvirus infection in the lower respiratory tract as well as to impaired immunophenotype, as patients with poor outcome showed severe lymphopenia, affecting in particular T (CD3+) cells, since the first days of ICU hospitalization. In conclusion, these results indicate that herpesviruses lower respiratory tract infection, which occurs more frequently following influenza virus infection, can be a negative prognostic marker. An independent risk factor for ICU patients with ARDS is an impaired immunophenotype.

One of the core diagnostic criteria used by Analgesic, Anesthetic, and Addiction Clinical Trial Translations Innovations Opportunities and Networks-American Pain Society Pain Taxonomy (AAPT to define chronic SCD pain is the presence of pain on a “majority of days” in the past 6 months in one or more locations. The frequency characteristic of “majority of days” is adapted from the criteria of 15 days or more per month, used to define chronic migraine, but there are inadequate data to support this cutoff in SCD. Using an existing dataset of adults with SCD who completed patient-reported outcomes of pain interference, physical functioning, anxiety, depression, and fatigue using the National Institutes of Health (NIH patient-reported outcomes measures information system (PROMIS short-form instruments, we examined the association of the presence of pain on 3 or more days per week with patient-reported outcomes of functioning. In unadjusted analyses, presence of pain on 3 or more days a week was associated with higher median PROMIS scores of pain interference, anxiety, and depression. Median PROMIS scores of fatigue and physical function were worse in women compared with men in unadjusted analyses. We did not find any difference in median PROMIS pain scores between adults aged ≤35 years compared with those aged ≥35 years. In linear regression models, after adjustment for age and sex, the presence of pain on 3 or more days a week was found to be associated with worse pain interference and anxiety. These data support

Stressful anesthesia induction has psychological adverse effects that recur with repeated anesthesia, can lead to increased pediatric discomfort during the recovery period, and may even induce reactionary postoperative behavior. A randomized controlled trial was performed to assess the impact of parental presence during induction of anesthesia (PPIA on preoperative anxiety of pediatric patients and their parents at three different times, cooperation of child with anesthesiologist at induction of anesthesia, and parental satisfaction.Patients and methods: A total of 96 pediatric patients undergoing elective minor surgery (ASA 1–2 were randomly divided into two groups. Both groups received oral midazolam (0.5 mg/kg at least 20 minutes before surgery, but in the PPIA group, the parents were also present in the operating room until loss of consciousness of child at anesthesia induction. Anxiety in the patients (as measured by the modified Yale Preoperative Anxiety Scale [mYPAS] and parents (as measured by the State and Trait Anxiety Inventory [STAI], the Induction Compliance Checklist (ICC, and parental satisfaction (as measured by visual analog scale were assessed. Results: There was no significant difference in the mean anxiety scores (mYPAS of participants in the control and PPIA groups at ward T0 and upon arrival to operating room T1 (P>0.05.

This study was conducted to evaluate the effect of clinical factors on the treatment outcomes of lung cancer patients with active epidermal growth factor receptor (EGFR) mutations treated by first-line tyrosine kinase inhibitors (TKIs). Patients of stage IIIb or IV lung adenocarcinoma harboring mutated EGFR were enrolled between March 2010 and June 2014 and followed up until December 2015. The effects of various clinical features, such as age, sex, smoking history, EGFR mutation types, TKIs used, presence of pleural effusion, metastatic sites on progression-free survival (PFS) and overall survival (OS), were analyzed retrospectively. A total of 104 patients were included in this study. Patients with pleural effusion at initial diagnosis had significantly shorter PFS and OS than those without pleural effusion (median PFS: 8.2 months vs 15.3 months, P = 0.0004; median OS: 16.3 months vs 28.2 months, P = 0.0003). Univariate analysis revealed that being male or a smoker was associated with short PFS, whereas smoking history, bony metastasis and malignant pleural effusion were associated with poor OS. Stepwise multivariate Cox regression analysis showed that the presence of pleural effusion and different TKI use were independent prognostic factors for PFS [hazard ratio [HR] = 2.50 (95% confidence interval [CI], 1.53-4.10), P = 0.0003 and HR = 0.55 (95% CI, 0.31-0.97), P = 0.0396, respectively], whereas the presence of pleural effusion and liver metastasis were associated with poor OS [HR = 2.79 (95% CI: 1.46-5.30), P = 0.0018 and HR = 2.12 (95% CI, 1.02-4.40), P = 0.0440, respectively]. The presence of pleural effusion predicts poor PFS and OS in lung adenocarcinoma patients receiving TKIs as the first-line treatment. Additional studies are warranted to elucidate the underlying mechanisms and determine novel strategies for improving the outcome of these patients. © 2017 John Wiley & Sons Australia, Ltd.

A symbolic encoding scheme, based on the ordinal relation between the amplitude of neighboring values of a given data sequence, should be implemented before estimating the permutation entropy. Consequently, equalities in the analyzed signal, i.e. repeated equal values, deserve special attention and treatment. In this work, we carefully study the effect that the presence of equalities has on permutation entropy estimated values when these ties are symbolized, as it is commonly done, according to their order of appearance. On the one hand, the analysis of computer-generated time series is initially developed to understand the incidence of repeated values on permutation entropy estimations in controlled scenarios. The presence of temporal correlations is erroneously concluded when true pseudorandom time series with low amplitude resolutions are considered. On the other hand, the analysis of real-world data is included to illustrate how the presence of a significant number of equal values can give rise to false conclusions regarding the underlying temporal structures in practical contexts. - Highlights: • Impact of repeated values in a signal when estimating permutation entropy is studied. • Numerical and experimental tests are included for characterizing this limitation. • Non-negligible temporal correlations can be spuriously concluded by repeated values. • Data digitized with low amplitude resolutions could be especially affected. • Analysis with shuffled realizations can help to overcome this limitation.

The aim of this study was to evaluate whether the maximum standardized uptake value (SUVmax) of (18)F-fluorodeoxyglucose (FDG) correlates with the International Prognostic Index (IPI) and the presence of extranodal involvement in patients with Diffuse Large B-Cell Lymphoma (DLBCL). 77 patients (age: 57.2±18.5, 40F, 37M) with DLBCL who underwent FDG PET/CT for initial staging were included. SUVmax of the predominant lesions were compared to Ann Arbor stage, IPI scores, the presence of extranodal involvement and the number extranodal sites. PET/CT detected nodal (n:25) and extranodal involvement (n:52) in all the patients. In 27 patients, extranodal disease could only be detected by PET. SUVmax of the predominant lesion in patients with extranodal disease was significantly higher than that of the patients who had only nodal disease (25±12 vs. 15.3±10 respectively, p=0.001). SUVmax significantly correlated with IPI scores; the average SUVmax was significantly correlated with the IPI: Mean SUVmax of the predominant lesion was 13.9±9.5 in patients with low risk (IPI=0-1), 14.2±8.8 in low-intermediate risk group (IPI=2) whereas 26.6±9.5 in high-intermediate risk group (IPI=3) and 25±13.6 in high risk group patients (IPI=4-5) (p=0.002). SUVmax was not correlated with clinical stage, the number of extranodal sites and serum LDH levels. FDG uptake correlates with IPI and the presence of extranodal involvement in DLBCL. PET is a powerful method to detect extranodal disease in DLBCL. The correlation of SUVmax with these prognostic factors may highlight the importance of pretreatment FDG uptake as a metabolic marker of poor prognosis for patients with DLBCL.

Full Text Available Background and Design: Practical training of medical students, especially in specialties such as dermatology, is performed in outpatient clinics where mostly outpatients are encountered. The aim of this study was to compare patients’ perspectives on medical students in two university hospitals (X–Y situated in different regions of Turkey. Materials and Methods: A total of 250 patients, who visited outpatient clinics of X (group 1 and Y (group 2 university hospitals during practical training for fifth year medical students, were included in this study. A questionnaire composed of 16 items was filled by all patients. The first eight questions were about patients’ consent and preferences on the presence of medical students during their interview and the remaining eight questions inquired patients’ overall thoughts on medical students. Results: The patients in both groups were willing to be a part of the educational programme of medical students (39.8%, 53.5%, respectively. The patients were aware that they had the right to refuse the presence of medical students (61.0%, 62.3% and majority wanted to be informed on the presence of medical students during the interview (72.4%, 80.7%. While patients in group 1 evaluated being with medical students as pleasurable (43.1%, patients in group 2 did not agree (44.7%. In addition, both groups were not bothered to share personal information with medical students (50.4%, 44.7% and stated that they would recommend their friends and relatives to have a physical examination done by medical students (51.2%, 41.2%. Conclusion: The active role of medical students during dermatology training is positively viewed by patients in both western and eastern parts of our country. The patients’ request on being informed for the presence of medical students during clinical examination reveals the requirement of oral and written informed consent.

The most common aetiologies of acute pancreatitis (AP) are gallstones, alcohol and idiopathic. The impact of the aetiology of AP on the extent and morphology of pancreatic and extrapancreatic necrosis (EXPN) has not been clearly established. The aim of the present study was to assess the influence of aetiology on the presence and location of pancreatic necrosis in patients with AP. We carried out a post-hoc analysis of a previously established multicentre cohort of patients with AP in whom a computed tomography was available for review. Clinical data were obtained from the medical records. All computed tomographies were revised by the same expert radiologist. The impact of aetiology on pancreatic and EXPN was calculated. In total, 159 patients with necrotizing pancreatitis were identified from a cohort of 285 patients. The most frequent aetiologies were biliary (105 patients, 37%), followed by alcohol (102 patients, 36%) and other aetiologies including idiopathic (78 patients, 27%). No relationship was found between the aetiology and the presence of pancreatic necrosis, EXPN, location of pancreatic necrosis or presence of collections. We found no association between the aetiology of AP and the presence, extent and anatomical location of pancreatic necrosis.

We prepared a database covering young-mature adulthood and investigated the clinical usefulness of the evaluation. Subjects and methods: One hundred seven patients with major depressive disorder (MDD, 74 patients with bipolar disorder (BD, and 240 healthy control subjects underwent 1.5T magnetic resonance imaging scanning. Using new VBM software and databases covering young-mature adults and the elderly, target volumes of interest were set in the sgACC and scACC, four indicators (severity, extent, ratio, and whole-brain extent were determined, and the presence or absence of atrophy of the sgACC and scACC was evaluated on the basis of the indicators. In addition, the relationships between the presence or absence of atrophy of the sgACC and scACC and performance of diagnosing MDD and BD and therapeutic drugs were investigated. Results: It was clarified that the disease is likely to be MDD when atrophy is detected in the sgACC, and likely to be BD when no atrophy is detected in the sgACC but is detected in the scACC. Regarding the relationship with therapeutic drugs, it was clarified that, when

Osteoporosis-related fractures are one of the complications of Graves' disease. This study hypothesized that the different actions of thyroid-stimulating hormone receptor (TSHR) antibodies, both stimulating and blocking activities in Graves' disease patients might oppositely impact bone turnover. Newly diagnosed premenopausal Graves' disease patients were enrolled (n = 93) and divided into two groups: patients with TSHR antibodies with thyroid-stimulating activity (stimulating activity group, n = 83) and patients with TSHR antibodies with thyroid-stimulating activity combined with blocking activity (blocking activity group, n = 10). From the stimulating activity group, patients who had matched values for free T4 and TSH binding inhibitor immunoglobulin (TBII) to the blocking activity group were further classified as stimulating activity-matched control (n = 11). Bone turnover markers BS-ALP, Osteocalcin, and C-telopeptide were significantly lower in the blocking activity group than in the stimulating activity or stimulating activity-matched control groups. The TBII level showed positive correlations with BS-ALP and osteocalcin levels in the stimulating activity group, while it had a negative correlation with the osteocalcin level in the blocking activity group. In conclusion, the activation of TSHR antibody-activated TSH signaling contributes to high bone turnover, independent of the actions of thyroid hormone, and thyroid-stimulation blocking antibody has protective effects against bone metabolism in Graves' disease.

To determine cutoff values of late-night salivary cortisol (LNSC) using an electrochemiluminescent immunoassay and investigate whether the diagnostic performance of the assay is influenced by the presence of obesity or polycystic ovary syndrome (PCOS). A total of 124 subjects comprising 25 patients with Cushing syndrome (CS), 44 with PCOS (22 nonobese and 22 obese), 21 with constitutional obesity (CO), and 34 healthy subjects (HS) were included in the study. Two consecutive LNSC samples were collected from all participants. The median LNSC levels of patients with CS were significantly higher than LNSC levels of HS, patients with CO, and obese and nonobese patients with PCOS, respectively (P.05 for all). The cutoff values and corresponding sensitivity and specificity were similar between the groups. The comparisons of the area under curve of the first LNSC (0.963; 95% confidence interval [CI], 0.910 to 0.989), second LNSC (0.954; 95% CI, 0.898 to 0.984), and the mean of two consecutive LNSC (mLNSC) values (0.962; 95% CI, 0.909 to 0.989) did not differ significantly (P>.05 for all). A cutoff value for mLNSC of 7.45 nmol/L yielded a sensitivity of 100% and specificity of 87.5% in HS. In conclusion, LNSC is a reliable test with high diagnostic accuracy in both HS and patients with PCOS and obesity.

Full Text Available BACKGROUND Opioid dependence is a major public health problem in Kerala. Presence of psychiatric disorder among opioid dependent patients worsens the scenario. To date no attempts have been made to analyse the magnitude and pattern of comorbid psychiatric disorders in the state. MATERIALS AND METHODS We assessed 30 patients with ICD-10 diagnosis of opioid dependence syndrome for the presence of comorbid psychiatric disorders using structured clinical interview for DSM IV Axis 1 disorder (SCID-1. Patients with opioid withdrawal state, delirium and acute medical emergencies were excluded. RESULTS 56.7% of our subjects had a comorbid psychiatric disorder. Major depressive disorder was the most common one (n=7, 23.3%. Prevalence of other disorders were generalised anxiety disorder (n=6, 20%, bipolar affective disorder (n=3, 10% and schizophrenia (n=1, 3.3%. CONCLUSION Comorbid Psychiatric disorders are highly prevalent in opioid dependence. There is a need for further large sample studies in the areas of comorbidities and in the integrated strategies for the identification and management of both opioid dependence and comorbid psychiatric disorders.

Purpose: The purpose of this study was to examine factors associated with the presence of secondary external and internal lymphedema in patients with head-and-neck cancer (HNC). Methods and Materials: The sample included 81 patients {>=}3 months after HNC treatment. Physical and endoscopic examinations were conducted to determine if participants had external, internal, and/or combined head-and-neck lymphedema. Logistic regression analysis was used to examine the factors associated with the presence of lymphedema. Results: The following factors were statistically significantly associated with presence of lymphedema: (1) location of tumor associated with presence of external (P=.009) and combined lymphedema (P=.032); (2) time since end of HNC treatment associated with presence of external (P=.004) and combined lymphedema (P=.005); (3) total dosage of radiation therapy (P=.010) and days of radiation (P=.017) associated with the presence of combined lymphedema; (4) radiation status of surgical bed was associated with the presence of internal lymphedema, including surgery with postoperative radiation (P=.030) and (salvage) surgery in the irradiated field (P=.008); and (5) number of treatment modalities associated with external (P=.002), internal (P=.039), and combined lymphedema (P=.004). No demographic, health behavior-related, or comorbidity factors were associated with the presence of lymphedema in the sample. Conclusions: Select tumor and treatment parameters are associated with increased occurrence of lymphedema in patients with HNC. Larger and longitudinal studies are needed to identify adjusted effects and causative risk factors contributing to the development of lymphedema in patients with HNC.

Background: Nowadays, endoscopic management of ureteropelvic junction (UPJ) obstruction is the treatment of choice. However, in the presence of crossing vessels, the success rate of endoscopic management decreases and the risk of hemorrhagic and vascular complications rises. The purpose of this study is to evaluate patients with UPJ obstruction using contrast enhanced multidetector computed tomography (CT) angiography to aid in surgical planning and management. Patients and methods: Between 2001 and 2005, 27 patients (mean age: 43 years; age range: 17-75 years) with UPJ obstruction were studied with multidetector CT angiography. Identification and characterization of crossing vessels was performed with multidirectional images and three-directional reconstructions. Results: 12 patients (44%) were found to have 16 crossing vessels (vessels in contact with the UPJ or within a vicinity of less than 2 mm). Nine of these vessels were arteries and seven were veins. Nine vessels crossed anteriorly, two posteriorly, and one anteromedially. Endopyelotomy was contraindicated in these 12 patients due to the presence of crossing vessels. Eleven out of the 12 patients underwent a pyeloplasty by open surgery or laparoscopy, where the presence of crossing vessels was confirmed. One of the 12 patients did not undergo surgery. Conclusion: Multidetector CT angiography permits an adequate preoperative assessment of patients with UPJ obstruction as it is able to identify the presence and location of crossing vessels. Furthermore, it allows to study in detail the anatomy of the renal area and its vascular variants.

Transient anisocoria in a patient treated with nebulized ipratropium bromide

Renato Pejic

2017-09-01

Conclusions and importance: Presence of anisocoria may be a concerning neurological sign. If there are no other neurological or ophthalmological signs and symptoms and a recent ipratropium bromide inhalation treatment exists in the patient's history, we should consider iatrogenic side-effect of drugs as a possible reason of anisocoria and possibly spare the patient extensive and invasive diagnostic procedures that can also raise costs of treatment significantly. Observing neurological status and testing with 1% pilocarpine solution may be necessary to determine the etiology of this condition.

Full Text Available Background. We study the clinical significance and management of pulmonary venous obstruction in cancer patients. Methods. We conducted a prospective cohort study to characterize the syndrome that we term “pulmonary vein obstruction syndrome” (PVOS between January 2005 and March 2014. The criteria for inclusion were (1 episodes of shortness of breath; (2 chest X-ray showing abnormal pulmonary hilum shadow with or without presence of pulmonary edema and/or pleural effusion; (3 CT scan demonstrating pulmonary vein thrombosis/tumor with or without tumor around the vein. Results. Two hundred and twenty-two patients developed PVOS. Shortness of breath was the main symptom, which was aggravated by chemotherapy in 28 (13%, and medical/surgical procedures in 21 (9% and showed diurnal change in intensity in 32 (14%. Chest X-rays all revealed abnormal pulmonary hilum shadows and presence of pulmonary edema in 194 (87% and pleural effusion in 192 (86%. CT scans all showed pulmonary vein thrombosis/tumor (100% and surrounding the pulmonary veins by tumor lesions in 140 patients (63%. PVOS was treated with low molecular weight heparin in combination with dexamethasone, and 66% of patients got clinical/image improvement. Conclusion. Physicians should be alert to PVOS when shortness of breath occurs and chest X-ray reveals abnormal pulmonary hilum shadows.

Preoperative preparation of paediatric patients and their environment in order to prevent anxiety is an important issue in paediatric anaesthesia. Anxiety in paediatric patients may lead to immediate negative postoperative responses. When a child undergoes surgery, information about the child's anaesthesia must be provided to parents who are responsible for making informed choices about healthcare on their child's behalf. A combination of written, pictorial, and verbal information would improve the process of informed consent. The issue of parental presence during induction of anaesthesia has been a controversial topic for many years. Potential benefits from parental presence at induction include reducing or avoiding the fear and anxiety that might occur in both the child and its parents, reducing the need for preoperative sedatives, and improving the child's compliance even if other studies showed no effects on the anxiety and satisfaction level. The presence of other figures such as clowns in the operating room, together with one of the child's parents, is an effective intervention for managing child and parent anxiety during the preoperative period.

Symptom severity and neuropsychological deficits negatively influence functional outcomes in patients with schizophrenia. Recent research implicates specific types of biased thinking styles (e.g. jumping-to-conclusions) in the pathogenesis of schizophrenia. This is the first study to test the impact of jumping-to-conclusions on functional outcome in schizophrenia. The aim of the study was to investigate the association of psychopathology, neuropsychology and JTC with subjective quality of life, vocational outcome and housing status in schizophrenia. Analyses were carried out both cross-sectionally at baseline, and longitudinally over the course of symptomatic improvement in the immediate aftermath of a psychotic exacerbation. Seventy-nine patients with schizophrenia were included in the study. Data concerning the variables of interest were collected at baseline, after one month, and after six months. Positive symptomatology was the most significant predictor of subjective and vocational outcome and changes across time. Verbal memory deficits were associated with functional status cross-sectionally, whereas general cognitive capacity significantly predicted functional changes over time. Improvement of the jumping-to-conclusions bias positively affected vocational outcome. Though limited, the observed effect of this bias on real-world functioning highlights the possible usefulness of interventions aimed at improving (meta)cognitive deficits in schizophrenia.

Various aspects of a clinical session on 'High dose-rate afterloading in the treatment of cancer of the uterus' at the International Workshop, London in April 1978 are discussed. The results of high dose-rate afterloading treatment were at least as good as those of conventional low dose-rate therapy. However, there is still a need to optimize dose fractionation and technique according to the type and stage of the disease to achieve the best results with the least distress for the patient. It would appear that, at the doses used, side effects with high dose-rate afterloading were few and probably related to the external rather than to the intracavitary therapy. High dose-rate afterloading therapy has obvious social and economic advantages and is thus of interest to all countries. (U.K.)

Full Text Available Context: Hypothyroidism is a common public health problem in India. With iodine sufficiency, autoimmune thyroiditis is becoming the most important etiology of hypothyroidism. Often, thyroiditis is associated with other systemic autoimmune diseases. Aims: We undertook thisobservational study to find the prevalence of systemic lupus erythematosus (SLE amongst the hypothyroid patients at our Institution. Settings and Design: This is probably the first study of its kind from India. Materials and Methods: 185 patients with diagnosed hypothyroidism were included and screening for SLE was done by standard epidemiological criteria. Majority of the patients (63.8% were young adults (20-40 years. Statistical Analysis Used: Two by two contingency tables were analyzed by Chi-square test or Fisher′s exact test as needed. Logistic regression model was used considering the presence of SLE as a dependent variable. Results: Eleven (5.94% patients were found to have SLE. However, anti nuclear factor was positive in 145 cases (78.4%. Of the patients with SLE, 8 (72.7% were found to be anti TPO positive, but the titers of ANF and anti TPO did not correlate. Presence of discoid rash, haematological criteria and presence of antibodies like anti-dsDNA were significantly correlated with the presence of SLE in hypothyroid patients. Presence of ANF was also correlated with the grade of goiter (r=0.62; P<0.05. Also four patients with SLE had a positive family history (OR=9.37. Logistic regression model showed anti-TPO has OR=1.54 (P=0.02 for the development of SLE. Conclusions: Prevalence of SLE in hypothyroid patients is high compared to the general population, especially, as thyroiditis is very common in SLE.

Full Text Available Background: Obesity is a well-known principal risk factor for metabolic disorders and cardiovascular diseases. Resistin is one of adipocyte-derived molecules, which plays important roles in inflammation as well as in endocrine and cardiovascular systems. Objectives: The present study aimed to determine the association between serum resistin level and presence/severity of Coronary Heart Disease (CHD. Patients and Methods: This cross-sectional study was conducted on 155 individuals referred for coronary angiography. Information about the patients’ age, gender, and cardiovascular risk factors was recorded. Their weight, height, and waist and hip circumferences were measured, as well. Each coronary angiogram was reported for two scoring methods (number of vessel diseases (usual method and Gensini scoring system by one cardiologist who was not aware of the participants’ serum resistin levels. Then, the relationship between serum resistin level and presence/severity of CHD was evaluated. Results: The results revealed no significant associations between the mean serum resistin level and the presence of CHD by both methods of evaluation of the coronary angiograms after adjustment for all conventional risk factors for CHD. In addition, no significant association was detected between serum resistin level and the severity of CHD based on the usual method of reporting the coronary angiograms (number of vessel diseases (P = 0.332. Yet, serum resistin level was positively correlated to body mass index and waist and hip circumferences and negatively related to height and fasting blood sugar level. Moreover, no linear correlation was found between serum resistin level and Gensini score (P = 0.35. Finally, hip circumference (P = 0.002 and height (P = 0.018 were determined as the predictors of serum resistin level. Conclusions: This cross-sectional study showed no significant associations between serum resistin level and presence/severity of CHD.

Patients and methods: The study was observational and cross-sectional. One-hundred and sixty-four females between 45 and 65 years of age were evaluated. The sample was divided into two groups, according to WC: Group ≤80 (G≤80 was composed of females in whom WC was up to 80 cm; and Group >80 (G>80 was composed of females with WC above 80 cm. The subjects were assessed in terms of sociodemographic data, pre-existing conditions, urogynecological and obstetric history, and the presence of lower UTS (LUTS, as well as physical examination, measurement of WC, height, and weight. The PFM assessment was made by perineometry. To compare the mean between groups, the independent samples t-test was applied, and to correlate the WC with perineometry and LUTS, the Pearson’s correlation test was used. Results: The final sample was composed of 156 patients. The average age of participants was 55.21 (±24.5 years in G≤80 and 57.23 (±6.12 years in G>80. There were significant differences regarding the presence of LUTS between the groups (P<0.05; as to the perineometry, there was a significant difference (P=0.03 between the groups: 38.68±13.63 cmH2O for G≤80 and 30.11±11.20 cmH2O for G>80. There was a correlation between the presence of urinary urgency (r=0.7; P=0.00, nocturia (r=0.7; P=0.00, and urinary incontinence (r=0.9; P=0.00 with WC. Conclusion: Females with larger abdominal diameter have a higher prevalence of LUTS such as urinary incontinence, nocturia, and urinary urgency, as well as a lower PFM

2016-12-01

Full Text Available Aim: To evaluate the survival of patients after surgery of the esophagus/cardia using the transthoracic and transhiatal methods. Material and methods : In the years 2007–2011, 102 patients were radically treated for cancer of the esophagus/cardia: 24 women and 78 men at the average age of 59.5. There were 38 transthoracic procedures and 64 transhiatal procedures. All patients had a conduit made from the stomach, led through lodges in the esophagus and combined with the stump of the esophagus in the neck following the Collard method. Two-pole lymphadenectomies were performed in all patients. Results: Patients after transthoracic procedures had statistically more (p < 0.05 lymph nodes removed than patients after transhiatal procedures. The 5-year survival rates in transhiatal and transthoracic procedures did not statistically differ, being 8% and 0% respectively. The length of patient survival was influenced by metastases in the nearby lymph nodes (p < 0.0001 and the presence of adenocarcinoma. Conclusions : Surgical access (transhiatal and transthoracic surgery does not affect the 5-year survival rates. Transhiatal surgery allows a greater number of lymph nodes to be removed. The main factor influencing the 5-year survival rate is the presence of metastases in the nearby lymph nodes.

The purpose of this study was to assess if the presence of information including the pretest probability (Wells score), other known risk factors, and symptoms given on referrals for computed tomography (CT) pulmonary angiography correlated with prevalence rates for pulmonary embolism (PE). Also, to evaluate for differences between a university and a regional hospital setting regarding patient characteristics, amount of relevant information provided on referrals, and prevalence rates for pulmonary embolism. Retrospective review of all consecutive referrals (emergency room, inpatient, and outpatient) for CT performed on children and adults for suspected PE from two sites: a tertiary (university) hospital (site 1) and a secondary (regional) hospital (site 2) over a 5-year period. The overall prevalence rate was 510/3641 or 14% of all referrals. Significantly higher number of males had a positive CT compared to women (18% versus 12%, P relevant information on the referral and the probability for positive finding existed, a slight trend was noted (P = .09). In two categories, "hypoxia" and "signs of deep vein thrombosis," the presence of this information conferred a higher probability for pulmonary embolism, P information conferred a higher probability for pulmonary embolism. The amount of relevant clinical information on the request did not correlate with prevalence rates, which may reflect a lack of documentation on the part of emergency physicians who may use a "gestalt" approach. Request forms likely did not capture all relevant patient risks and many factors may interact with each other, both positively and negatively. Pretest probability estimations were rarely performed, despite their inclusion in major society guidelines. Copyright © 2013 AUR. Published by Elsevier Inc. All rights reserved.

To evaluate the effects of presence of hydronephrosis on micropercutaneous nephrolithotomy (micro-PNL) surgery. A retrospective analysis of 112 patients who underwent microperc surgery between December 2012 and April 2014 was performed. Patients were evaluated in two groups according to whether the presence of hydronephrosis. Stone size and location, fluoroscopy and operation time, stone-free rates and patient-related parameters were prospectively recorded into a centralized computer-generated system. A total of 58 patients in Group 1 with hydronephrosis and 54 patients in Group 2 with no hydronephrosis were analyzed. There was no statistically significant difference in terms of stone sizes and body mass indexes (BMI) in comparison of groups (155.2 ± 93.06 vs. 143.70 ± 70.77 mm(2), p = 0.856 and 27.6 ± 4.2 vs. 26.7 ± 3.2 kg/m(2), p = 0.625). The success rates were similar (91.3 vs. 92.5%, p = 0.341). While the mean operation time and fluoroscopy time in Group 1 were 44.2 ± 23.62 min and 105.3 ± 47 s, it was 38.8 ± 26.4 min and 112.53 ± 68.3 s in Group 2, but there was no statistical difference in comparison of both groups. The mean attempts of percutan puncture were 1.35 ± 0.47 in Group 1 and 1.76 ± 0.31 in Group 2 (p = 0.185). We also found no statistical differences regarding mean hemoglobin change and hospitalization time, respectively (p = 0.685 and p = 0753). In comparison of grades of hydronephrosis, there was no statistically significant difference in subgroups analysis. The presence of hydronephrosis does not affect success rates and operative time in micro-PNL procedures significantly. Micropercutaneous nephrolithotomy is technically feasible and efficacious both in hydronephrotic and non-hydronephrotic kidneys.

Human Papilloma Virus (HPV) infection can be a predisposing condition for the development of squamous cell papilloma (SCP) of the esophagus, which can progress to dysplasia and to carcinoma as a result of chronic infection. The aim of the present study was to search for the presence of HPV in the esophageal SCP, and to genotype the detected HPV. Data from patients with definite diagnosis of SCP of the esophagus were identified from pathology records for two years period at different Hospitals. Slides from each patient were reviewed and samples with satisfactory papilloma tissues were submitted to molecular analysis. DNA has been isolated. DNA sequencing has been performed for genotyping HPV for all types. Our study group consisted of 21 women and 17 men (a total of 38 patients), mean age was 41 years (range 17-67 years). Most of the papillomas were located at mid-esophagus (68%). Eight out of 38 patients (21%) had associated erosive esophagitis, and fourteen patients (36.8%) had Helicobacter Pylori (H. pylori). Of the 38 SCP analyzed, seven (19%) were positive for HPV DNA. Three of them were of genotype 6, whereas four were of genotype 16, 18, 31, 81 that are known as highly oncogenic. There were no correlations between the presence of HPV and the patient's age, the presence of reflux esophagitis or H. pylori, smoking habit and the location of the papillomas. The presence of high-risk type HPV in esophageal SCP may implicate a role of the virus in the pathogenesis of the esophageal tumor.

Can presence of oral Fordyce's granules serve as a marker for hyperlipidemia?

Gaballah, Kamis Y.; Rahimi, Iman

2014-01-01

Background: Hyperlipidemia is a well-documented risk factor for coronary heart disease and a great wealth of clinical trials have shown that early detection of hyperlipidemia and prescribing drugs that lower elevated lipid levels reduce serious cardiovascular events, such as myocardial infarction, heart failure and stroke. Fordyce granules (FGs) are sebaceous glands without hair follicles, most often located under the epithelium of the cheek and the vermilion border of lip. The incidence of FGs is typically high and their presence is usually regarded as a normal variation of the oral mucosa. The aim of this study was to investigate the pattern of anatomical distribution and density of FGs and also to explore any potential relationship between the detection of FGs and the state of hyperlipidemia. Materials and Methods: A cross-sectional, prospective study was designed. The participants were divided into two groups; first group consisted of individuals with FGs and the second group included those with no FGs detected. All participants were fasting 9-12 h before they were subjected to a comprehensive oral examination and their blood was sampled and tested for complete lipid profile. The presence of FGs was scored based on the number of the granules and their anatomical distribution. Chi-square test was used and P < 0.05 was considered as significant. Results: A total of 350 patients were recruited for this study, nearly 90% (n = 314) elicit detectable FGs. The FGs were mainly located on the buccal mucosa with or without labial involvement and their density tend to reduce with age and also with smoking. Individuals with elevated lipid profile tend to have the highest score of the FGs. Conclusion: According to this report, the presence of high numbers of FGs in people with high risk factors for cardiovascular disease should not be neglected. PMID:25426145

Background Gout and osteoarthritis (OA) are the most prevalent arthritides, but their relationship is neither well established nor well understood. Objectives We assessed whether a diagnosis of gout or asymptomatic hyperuricemia (AH) is associated with increased prevalence/severity of knee OA. Methods 119 male patients ages 55–85 were sequentially enrolled from the primary care clinics of an urban VA hospital, assessed and categorized into 3 groups: gout (ACR Classification Criteria), AH ([serum urate] ≥ 6.8 mg/dL, no gout), and control ([serum urate] gout). 25 patients from each group subsequently underwent formal assessment of knee OA presence and severity (ACR Clinical/Radiographic Criteria, Kellgren-Lawrence (KL) grade). Musculoskeletal ultrasound was used to detect monosodium urate (MSU) deposition at the knees and 1st metatarsophalangeal (MTP) joints. Results 68.0% of gout, 52.0% of AH, and 28.0% of age-matched control subjects had knee OA (gout vs. control, P=0.017). Odds ratio for knee OA in gout vs. controls was 5.46 prior to, and 3.80 after adjusting for BMI. Gout subjects also had higher KL grades than controls (P=0.001). Subjects with sonographically-detected MSU crystal deposition on cartilage were more likely to have OA than those without (60.0 vs 27.5%, P=0.037), with crystal deposition at the 1st MTP joints correlating most closely with OA knee involvement. Conclusion Knee OA was more prevalent in gout patients vs. controls, and intermediate in AH. Knee OA was more severe in gout patients vs. controls. PMID:25710856

Ocular surface inflammation may lead to tear film instability, epithelial cell irregularities, and permeability, resulting in chronic symptomatic pain and fluctuating vision as well as negative surgical outcomes.Patients and methods: A retrospective single center medical chart review of 100 patients was conducted. All patients were tested with the InflammaDry test to determine if patients exhibited elevated levels of matrix metalloproteinase 9 (MMP-9. InflammaDry-positive patients were started on a combination of cyclosporine 0.05% twice daily, 2,000–4,000 mg oral omega-3 fatty acids, and frequent artificial tear replacement. InflammaDry-negative patients were started on 2,000–4,000 mg of oral omega-3 fatty acids and frequent artificial tear replacement. Each patient was retested at ~90 days. A symptom questionnaire was performed at the initial visit and at 90 days.Results: 60% of the patients with dry eye symptoms tested positive for elevated MMP-9 at the initial visit. 78% of all patients returned for follow-up at ~90 days including 80% (48/60 of the previously InflammaDry-positive patients and 75% (30/40 of the previously InflammaDry-negative patients. A follow-up symptom questionnaire reported at least 75% symptomatic improvement in 65% (31/48 of the originally InflammaDry-positive patients and in 70% (21/30 of the initially InflammaDry-negative patients. Symptomatic improvement of at least 50% was reported in 85% (41/48 of previously InflammaDry-positive patients and 86% (26/30 of previously InflammaDry-negative patients. Following treatment, 54% (26/48 of previously InflammaDry-positive patients converted to a negative InflammaDry result.Conclusion: Identifying which symptomatic dry eye

Purpose: To confirm the cortical thickness difference across the central sulcus (CS) visualized in the presence of vasogenic edema on MRI. Materials and methods: T2-weighted images of 70 cerebral hemispheres showing vasogenic edema infiltrating into subcortical white matter around the CS were studied retrospectively. Two neuroradiologists measured the cortical thickness of the anterior and posterior banks of the CS, precentral sulci (PrCS), and postcentral sulci (PoCS). Additionally, we compared the cortical thickness of the anterior and posterior banks of each sulcus visually using a grading scale. Results: On T2-weighted images, the cerebral cortex was highlighted by a high signal-intensity vasogenic edema in the adjacent white matter, and its thickness was readily measurable. The unique cortical thickness difference between the anterior and posterior banks of the CS were confirmed with measurements of 2.67 and 1.48 mm (p < 0.0001). The cortical measurements across other cerebral sulci were 2.04 and 1.95 mm (NS) for the PrCS, and 1.67 and 1.77 mm (NS) for the PoCS. The cortical thickness ratios were 1.86 for the CS, 1.05 for the PrCS, and 0.96 for the PoCS. On visual evaluation, the anterior bank of the CS was thicker than the posterior bank in 93% (65/70). For the PrCS and PoCS, the thickness of the anterior and posterior banks appeared to be equal in over 70% of the patients. Conclusion: A prominent cortical thickness difference across the CS in the presence of vasogenic edema was confirmed. This finding is considered to facilitate the identification of the CS in patients with brain tumors.

For the PrCS and PoCS, the thickness of the anterior and posterior banks appeared to be equal in over 70% of the patients. Conclusion: A prominent cortical thickness difference across the CS in the presence of vasogenic edema was confirmed. This finding is considered to facilitate the identification of the CS in patients with brain tumors

Despite the advantages of large, national datasets, one continuing concern is missing data values. Complete case analysis, where only cases with complete data are analyzed, is commonly used rather than more statistically rigorous approaches such as multiple imputation. This study characterizes the potential selection bias introduced using complete case analysis and compares the results of common regressions using both techniques following unicompartmental knee arthroplasty. Patients undergoing unicompartmental knee arthroplasty were extracted from the 2005 to 2015 National Surgical Quality Improvement Program. As examples, the demographics of patients with and without missing preoperative albumin and hematocrit values were compared. Missing data were then treated with both complete case analysis and multiple imputation (an approach that reproduces the variation and associations that would have been present in a full dataset) and the conclusions of common regressions for adverse outcomes were compared. A total of 6117 patients were included, of which 56.7% were missing at least one value. Younger, female, and healthier patients were more likely to have missing preoperative albumin and hematocrit values. The use of complete case analysis removed 3467 patients from the study in comparison with multiple imputation which included all 6117 patients. The 2 methods of handling missing values led to differing associations of low preoperative laboratory values with commonly studied adverse outcomes. The use of complete case analysis can introduce selection bias and may lead to different conclusions in comparison with the statistically rigorous multiple imputation approach. Joint surgeons should consider the methods of handling missing values when interpreting arthroplasty research. Copyright © 2017 Elsevier Inc. All rights reserved.

To explore the similarities and differences in factors that influence nurses' and physicians' decision-making related to family presence during resuscitation. Despite the growing acceptance of family presence during resuscitation worldwide, healthcare professionals continue to debate the risks and benefits of family presence. As many hospitals lack a policy to guide family presence during resuscitation, decisions are negotiated by resuscitation teams, families and patients in crisis situations. Research has not clarified the factors that influence the decision-making processes of nurses and physicians related to inviting family presence. This is the first study to elicit written data from healthcare professionals to explicate factors in decision-making about family presence. Qualitative exploratory-descriptive. Convenience samples of registered nurses (n = 325) and acute care physicians (n = 193) from a Midwestern hospital in the United States of America handwrote responses to open-ended questions about family presence. Through thematic analysis, decision-making factors for physicians and nurses were identified and compared. Physicians and nurses evaluated three similar factors and four differing factors when deciding to invite family presence during resuscitation. Furthermore, nurses and physicians weighted the factors differently. Physicians weighted most heavily the family's potential to disrupt life-saving efforts and compromise patient care and then the family's knowledge about resuscitations. Nurses heavily weighted the potential for the family to be traumatised, the potential for the family to disrupt the resuscitation, and possible family benefit. Nurses and physicians considered both similar and different factors when deciding to invite family presence. Physicians focused on the patient primarily, while nurses focused on the patient, family and resuscitation team. Knowledge of factors that influence the decision-making of interprofessional colleagues

Autoimmune hepatitis is a necroinflammatory disorder of unknown etiology characterized by the presence of circulating antibodies, hypergammaglobulinemia, and response to immunosuppression. It has the histological features of chronic hepatitis. The onset is usually insidious, but in some patients the presentation may be acute and occasionally severe. Certain drugs can induce chronic hepatitis mimicking autoimmune hepatitis. Different autoantibodies have been associated with this process but they are not detectable after drug withdrawal and clinical resolution. We describe a case of drug-induced acute hepatitis associated with antinuclear, antisoluble liver-pancreas and anti-smooth muscle autoantibodies in a 66-year-old woman. Abnormal clinical and biochemical parameters resolved after drug withdrawal, but six months later anti-soluble liver-pancreas antibodies remained positive and liver biopsy showed chronic hepatitis and septal fibrosis. Furthermore, our patient has a HLA genotype associated with autoimmune hepatitis. Patient follow-up will disclose whether our patient suffers from an autoimmune disease and if the presence of anti-soluble liver antigens could precede the development of an autoimmune hepatitis, as the presence of antimitochondrial antibodies can precede primary biliary cirrhosis.

Full Text Available Introduction: Inhibin-B is glycoproteins of the transforming growth factor-β superfamily, is produced almost exclusively by the Sertoli cells and has been proposed as direct markers of their function and indirect markers of spermatogenesis. Our objective was to evaluate the predictive value of serum Inhibin-B levels as an indicator of the presence of testicular spermatozoa in non-obstructive azoospermia (NOA, compared with other markers such as FSH and testicular volume. Material and methods: A total of 228 patients with idiopathic non-obstructive azoospermia (NOA were recruited in this prospective study. Inhibin-B in serum has been evaluated before sperm retrieval by Enzyme-Linked Immuno-Sorbent Assay (Elisa, in addition to FSH and testosterone. Testicular volume was measured by sonography. Testicular Fine Needle Aspiration (FNA and Testicular Sperm Extraction (TESE were performed for sperm retrieval. The patients were classified according to the presence or absence of Testicular spermatozoa into two groups (I and II respectively. Results: Spermatozoa were retrieved in 87 patients (38.16%, classified as group I and were absent in 141 patients (61.84% classified as group II. Mean serum Inhibin-B ± SD was significantly higher in group I than in group II, 71.77 versus 27.49 respectively (P < 0.001. The odds ratio of Inhibin-B for success of sperm retrieval was 1.0409 (95% CI: 1.0286–1.0533. Serum Inhibin-B demonstrated that the best inhibin-B value threshold for discriminating between successful and failed sperm retrieval was 35 pg/ml, with a sensitivity of 75.86 (95% Confidence interval [CI]: 65.5–84.4 and specificity of 80.85 (CI: 73.4–87.0 for the prediction of the presence of testicular spermatozoa as determined by the receiver operating characteristic (ROC curve analysis and area under curve (AUC. Conclusions: Inhibin-B might be a predictive marker of persistent spermatogenesis in the men with non-obstructive azoospermia.

Fanconi anaemia is a heterogeneous genetic disease, where 12 complementation groups have been already described. Identifying the complementation group in patients with Fanconi anaemia constitutes a direct procedure to confirm the diagnosis of the disease and is required for the recruitment of these patients in gene therapy trials. To determine the subtype of Fanconi anaemia patients in Spain, a Mediterranean country with a relatively high population (23%) of Fanconi anaemia patients belonging to the gypsy race. Most patients could be subtyped by retroviral complementation approaches in peripheral blood T cells, although some mosaic patients were subtyped in cultured skin fibroblasts. Other approaches, mainly based on western blot analysis and generation of nuclear RAD51 and FANCJ foci, were required for the subtyping of a minor number of patients. From a total of 125 patients included in the Registry of Fanconi Anaemia, samples from 102 patients were available for subtyping analyses. In 89 cases the subtype could be determined and in 8 cases exclusions of common complementation groups were made. Compared with other international studies, a skewed distribution of complementation groups was observed in Spain, where 80% of the families belonged to the Fanconi anaemia group A (FA-A) complementation group. The high proportion of gypsy patients, all of them FA-A, and the absence of patients with FA-C account for this characteristic distribution of complementation groups.

Food intolerance in adults is mostly associated with vague symptoms and not clearly related to atopy and food allergy. A combination of different pathogenetic mechanisms may be responsible for the symptoms. The aim of this study was to describe patients with a history of food-related gastrointestinal symptoms in relation to the presence of mucus in the stools, joint swelling and arthralgia and to determine whether or not there is an association between the presence of these parameters, atopic disease and the presence of immune complexes in serum. Fifty-eight patients consecutively referred to our clinic with food-related gastrointestinal symptoms were investigated. Thirty-five patients (60%) had mucus in their stools, 24 patients (41%) complained about joint swelling and 41 patients (71%) had arthralgia. There were no correlations between these parameters and atopy according to Phadiatope test or skin prick test (SPT). No correlations were found between the occurrence of mucus in the stools, arthralgia and joint swelling. There were significantly higher levels of circulating immune complexes in patients with a history of arthralgia compared with patients with no such history (P mucus in the stools. However, there were significant positive correlations between food-related gastrointestinal symptoms in the following instances: chocolate-induced gastrointestinal symptoms and mucus in the stools (P = 0.006), vegetable-induced gastrointestinal symptoms and mucus in the stools (P = 0.002) and meat-induced gastrointestinal symptoms and mucus in the stools (P = 0.003). In a group of individuals without food-related symptoms investigated separately, a very low frequency of mucus in the stools, joint swelling and arthralgia was seen (none, two and three individuals of the 20 subjects, respectively). Of 41 patients with immediate onset of gastrointestinal symptoms, 20 were atopic according to Phadiatope and SPT. Of 11 patients with late onset of symptoms 10 were negative in

Full Text Available Objective: In oncology practice, nutrition and also metabolic activity are essential to support the nutritional status and prevent malignant cachexia. It is important to evaluate the patients and plan the maneuvers at the start of the therapy. The primary objective of the study is to define the nutritional status of hospitalized patients and the factors affecting it in order to define the most susceptible patients and maneuvers for better nutritional support. Methods: Patients hospitalized in oncology clinic for therapy were evaluated for food intake and nutritional status through structured interviews. The clinical properties, medical therapies, elements of nutritional support were noted and predictors of inadequate nutritional status (INS were analyzed. Results: Four hundred twenty three patients, between 16-82 years old (median: 52 were evaluated. Nearly half of the patients (185, 43% reported a better appetite at home than in hospital and declared that hospitalization is an important cause of loss of appetite (140/185, 75.6%. Presence of nausea/vomiting (N/V, depression, age less than 65 and use of non-steroidal anti-inflammatory drugs (NSAIDs were associated with increased risk of INS in hospitalized cancer patients. On the contrary, steroid medication showed a positive impact on nutritional status of cancer patients. Conclusion: N/V, younger age, presence of depression and NSAIDs medication were associated with INS in hospitalized cancer patients. Clinicians should pay more attention to this group of patients. In addition, unnecessary hospitalizations and medications that may disturb oral intake must be avoided. Corticosteroids are important tools for managing anorexia and INS.

Full Text Available The purpose of our study was to investigate the lipid profile in patients with polycystic ovary syndrome (PCOS. Methods: a retrospective review of the medical records of female patients addressing for a consultation in a private healthcare network in Cluj-Napoca between 2009 and 2011 was performed. Patients with complete lipid profile and without previous treatment were included in the PCOS group. PCOS was diagnosed using Rotterdam criteria for PCOS. Healthy female patients matched for age but without PCOS were included in the control group. Results: Compared with healthy women, women with PCOS presented higher total cholesterol levels (mean difference = 27.5 mg/dl for total cholesterol, p = 0.004 and LDL-cholesterol (mean difference = 38.1 mg/dl, p < 0.001. HDL-cholesterol displayed lower levels in PCOS patients compared with healthy women (44.4±12.2 mg/dl vs. 50.5±12.2 mg/dl, p = 0.02. No difference was observed between groups in terms of triglycerides levels. In regression analysis both total cholesterol and LDL-cholesterol were positively associated only with the presence of PCOS (β = 0.30, p = 0.01 for total cholesterol, β = 0.44, p<0.001 for LDL-cholesterol. No association was observed between HDL-cholesterol levels and the presence of PCOS. Conclusion: The results of our study show that women with PCOS have altered lipid profile, with higher cholesterol levels (both total and LDL and lower HDL cholesterol compared with healthy women. These lipid parameters were associated with the presence of PCOS and not with parameters describing body weight.

Full Text Available Background. The sense of presence is an important aspect of interaction with virtual reality applications. Earlier we suggested that presence can depend on cognitive control. The latter is a set of meta-cognitive processes which are responsible for configuring the cognitive system for the accomplishment of specific tasks with respect to a given context. In particular, cognitive control helps in preventing interference from the task-irrelevant variables. Objective. is study aimed at investigation of the possible relationship between interference control and aspects of presence. Design. Thirty-nine subjects (32 female and 7 male, aged 18 to 27 years participated in the study. The subjects were assessed via a battery of interference control tasks (Flanker Task, Go/No Go task, antisaccade task and performed a virtual scenario (navigating within an array of randomly placed virtual digits in correct numerical order in high-immersion (CAVE and low-immersion (standard computer display virtual environments. Afterwards, the subjects completed a Russian version of the ITC-Sense of Presence inventory. Results. We found that interference control is generally related to the sense of presence, especially in the CAVE (high-immersion environment. Sensory interference control was most strongly associated with various aspects of presence (overall presence score, spatial presence, and emotional involvement. Motor interference control was associated with spatial presence and emotional involvement, but this relationship was weaker than was the case with sensory interference control. Low-immersion virtual environments attenuate some of these links between interference control and presence so that only sensory interference control remains a notable predictor of presence. Conclusion. Interference control is positively associated with presence in virtual environments with varying immersion levels. is may reflect a more general cause-and-effect relationship between

The existing family presence literature indicates that implementation of a family presence policy can result in positive outcomes. The purpose of our evidence-based practice project was to evaluate a family presence intervention using the 6 A's of the evidence cycle (ask, acquire, appraise, apply, analyze, and adopt/adapt). For step 1 (ask), we propose the following question: Is it feasible to implement a family presence intervention during trauma team activations and medical resuscitations in a pediatric emergency department using national guidelines to ensure appropriate family member behavior and uninterrupted patient care? Regarding steps 2 through 4 (acquire, appraise, and apply), our demonstration project was conducted in a pediatric emergency department during the implementation of a new family presence policy. Our family presence intervention incorporated current appraisal of literature and national guidelines including family screening, family preparation, and use of family presence facilitators. We evaluated whether it was feasible to implement the steps of our intervention and whether the intervention was safe in ensuring uninterrupted patient care. With regard to step 5 (analyze), family presence was evaluated in 106 events, in which 96 families were deemed appropriate and chose to be present. Nearly all families (96%) were screened before entering the room, and all were deemed appropriate candidates. Facilitators guided the family during all events. One family presence event was terminated. In all cases patient care was not interrupted. Regarding step 6 (adopt/adapt), our findings document the feasibility of implementing a family presence intervention in a pediatric emergency department while ensuring uninterrupted patient care. We have adopted family presence as a standard practice. This project can serve as the prototype for others. Copyright (c) 2010 Emergency Nurses Association. Published by Mosby, Inc.

It is characterized by various degrees of iris atrophy, corneal endothelial changes, uveal ectropion, corectopia, peripheral anterior synechiae (PAS and secondary glaucoma. The aim of the study was to illustrate forms of ICE syndrome, determine frequency of secondary glaucoma with emphasis on cases with uveal ectropion, analyze response to medicament treatment and the need for surgical treatment in intraocular pressure (IOP control. Methods. Patients underwent slit lamp examination, applanation tonometry, gonioscopy, ophthalmoscopy, Humphrey visual field testing and Heidelberg retina tomography. Patients were divided into two groups: group I, without uveal ectropion (22 patients and group II, with uveal ectropion (14 patients. Results. A total of 36 patients were examined in a 10-year period. The average age was 38 years, male to female ratio 1:2. Secondary glaucoma was confirmed in 26 (72.2% patients, out of which 12 (54.5% in group I and 14 (100% in group II. PAS were more frequent in group II. In group I, mean initial IOP was 37 mmHg, and after medicament treatment 26 mmHg. Secondary glaucoma was controlled in 50% and remaining 50% underwent surgical treatment. In group II, mean initial IOP was 49 mmHg, and after medicament treatment 32 mmHg. All 14 patients (100% underwent surgical treatment in order to achieve IOP control. Conclusion. ICE syndrome is a rare, progressive disease, with high incidence of secondary glaucoma, which is more frequent in cases with uveal ectropion. In these cases, medicament treatment is not effective and trabeculectomy with antimetabolite application is necessary.

Full Text Available Objective: to evaluate the accuracy of the defining characteristics of the excess fluid volume nursing diagnosis of NANDA International, in patients undergoing hemodialysis. Method: this was a study of diagnostic accuracy, with a cross-sectional design, performed in two stages. The first, involving 100 patients from a dialysis clinic and a university hospital in northeastern Brazil, investigated the presence and absence of the defining characteristics of excess fluid volume. In the second step, these characteristics were evaluated by diagnostic nurses, who judged the presence or absence of the diagnosis. To analyze the measures of accuracy, sensitivity, specificity, and positive and negative predictive values were calculated. Approval was given by the Research Ethics Committee under authorization No. 148.428. Results: the most sensitive indicator was edema and most specific were pulmonary congestion, adventitious breath sounds and restlessness. Conclusion: the more accurate defining characteristics, considered valid for the diagnostic inference of excess fluid volume in patients undergoing hemodialysis were edema, pulmonary congestion, adventitious breath sounds and restlessness. Thus, in the presence of these, the nurse may safely assume the presence of the diagnosis studied.

Full Text Available Introduction: The nasal Polyposis is a non-neoplastic chronic inflammatory process of the nasal mucosa. It causes a large impact to the patients' life quality. Objective: To analyze the characteristics of patients with polyposis in the Brazilian population. Method: 50 records of patients followed up in a tertiary hospital and submitted to surgical treatment of nasal polyposis were reviewed. The following variables were analyzed: age, sex, smoking, presence of asthma, presence of AAS intolerance and also the clinical manifestations: anterior and posterior rhinorrhea, nasal obstruction, hyposmia, sneezing and pruritus. The tomographic evaluation system applied was that of Lund-McKay. For statistical analysis we applied the chi-square test with p<0.05. Results: Out of 50 patients evaluated, 28 were male and 22 were female. The mean age range was of 40.8 years. The main clinical manifestation was nasal obstruction in 100% of the patients. In the tomographic evaluation, according to the Lund-McKay system, the average scoring was of 10.9. Discussion: No statistically significant difference was obtained in the patients' general symptoms compared to the patients with asthma or AAS intolerance. The difference in the Lund-McKay score was statistically significant in the populations studied. The symptoms were similar to the frequency of symptoms of other works. Conclusion: We concluded that the main complaint of the patients with nasal polyposis is nasal obstruction, the most affected age is of about 40 years old, without preference of sex. The severity of tomographic findings is higher in patients with asthma and AAS intolerance.

Full Text Available ntroduction: Chronic otitis media (COM is regarded as one of the disabling diseases which have a great influence on the quality of life. Because of the surgical approach of cholesteatoma, timely diagnosis is very important in management of patients with COM. The purpose of this study was to assess the frequency of cholesteatoma in patients with COM, demographic factors and disease related factors. Materials and Methods: In this retrospective study, medical records of 100 patients with COM who had surgery since 2005 to 2009 in Imam Reza Hospital were selected. Patients’ age, gender, duration of COM, clinical manifestations, location of perforation of tympanic membrane and presence or absence of cholesteatoma were analyzed by SPSS statistical software and some tables and graphs were planned. Results: patients   included 70 males and 30 females with an average age of 23.08 ± 11.35. Mean of COM duration was 8.04 ± 7.14 years. The most common manifestations of the disease were otorrhea (92% and hearing loss (80%. The most frequent type of tympanic perforation was total perforation. Frequency of cholesteatoma was 42% and it was more common in males than females (42.9% and 40%. Presence of choleasteatoma was related to gender, age, location of tympanic perforation, presence of otorrhea and hearing loss. Conclusion: Prevalence of cholesteatoma in patients  with COM  in  Mashhad  is more than  other  cites of Iran and  also other  countries, but it is less than prevalence of non cholesteatomatos COM. It is very important to pay more attention to patients with COM who are evaluated about presence of cholesteatoma, specially those with otorrhea, hearing loss, total perforation of tympanic membrane or male gender.

The purpose of this study was to evaluate the presence of bronchiectasis in coal workers with or without coal worker pneumoconiosis (CWT) and to assess the extent of bronchiectasis, severity of bronchial wall dilatation and thickening by high resolution computed tomography (HRCT). The patient group consisted of 78 patients (43 CWP; 35 non-CWP). Pneumoconiosis profusions of CWP workers were between p0/1 and p2/2 according to ILO 1980 chest X-ray classification. HRCT examinations of all subjects were evaluated for the presence, extent, dilatation and thickness of bronchiectasis. The diagnosis of bronchiectasis was put on 19 of 43 CWP (44.1 %) and 7 of 35 non-CWP workers (20.0 %). There were statistically significant differences between bronchiectasis positive and negative coal workers with CWP concerning age and exposure duration (P = 0.012 and 0.009, respectively). Then, multiple logistic regression analysis was performed to define exact risk factors. Exposure duration was only found to be related with presence of bronchiectasis ((odds ratio) OR = 1.494, 95 % confidence interval 1.168-1.912). The data from the present study shows that bronchiectasis is frequent and severe in CWP workers than without. Bronchiectasis is influenced by coal dust exposure. Thus, coal dust protection measures must be controlled efficiently to prevent bronchiectasis in coal workers.

Summary and Conclusions

This section summarizes the presentations and Panel discussions of the 4 technical sessions of the workshop: 1 - Regulatory cooperation on generic and design specific issues, MDEP working groups (EPR, AP1000), vendor inspection co-operation, digital I and C, and codes and standards (7 presentations); 2 - Regulatory positions on siting practices and enhancements as a result of lessons learned from Fukushima accident (5 presentations); 3 - Construction experience and regulatory oversight of new reactor construction activities (6 presentations); 4 - Lessons learned from regulatory licensing reviews of new reactor designs (6 presentations). The main workshop conclusions are listed as follows: - Harmonization is a long term goal and significant progress has been made. However, this long term objective needs to be associated with short term measurable steps; - MDEP approach to tackle on one side with specific technical subjects, and to strive harmonisation on generic topics was considered appropriate; - Convergence on technical requirements is more realistic than harmonization of codes and standard; - Beneficial early engagement of different stakeholders specially at the siting stage has been acknowledged; - Need to characterise the hazards and to keep updated the safety assessment (PSR); - Land use issues are important particularly after Fukushima; - Commissioning aspects (e.g. training aspects for inspectors) should be addressed by WGRNR taking into account MDEP interaction; - Importance of WGRNR ConEx Programme: construction experience sharing is a leverage for quality and so for a future safe operation of NPPs; - Capability of licensee to follow the responsibility of design changes (could be an issue for small utilities); - Importance of Periodic Safety Reviews to review and account for the design. Finally, the WGRNR has convened that a third conference should be held in about two years time (2014- 2015)

Full Text Available Background: Hyperlipidemia is a well-documented risk factor for coronary heart disease and a great wealth of clinical trials have shown that early detection of hyperlipidemia and prescribing drugs that lower elevated lipid levels reduce serious cardiovascular events, such as myocardial infarction, heart failure and stroke. Fordyce granules (FGs are sebaceous glands without hair follicles, most often located under the epithelium of the cheek and the vermilion border of lip. The incidence of FGs is typically high and their presence is usually regarded as a normal variation of the oral mucosa. The aim of this study was to investigate the pattern of anatomical distribution and density of FGs and also to explore any potential relationship between the detection of FGs and the state of hyperlipidemia. Materials and Methods: A cross-sectional, prospective study was designed. The participants were divided into two groups; first group consisted of individuals with FGs and the second group included those with no FGs detected. All participants were fasting 9-12 h before they were subjected to a comprehensive oral examination and their blood was sampled and tested for complete lipid profile. The presence of FGs was scored based on the number of the granules and their anatomical distribution. Chi-square test was used and P < 0.05 was considered as significant. Results: A total of 350 patients were recruited for this study, nearly 90% (n = 314 elicit detectable FGs. The FGs were mainly located on the buccal mucosa with or without labial involvement and their density tend to reduce with age and also with smoking. Individuals with elevated lipid profile tend to have the highest score of the FGs. Conclusion: According to this report, the presence of high numbers of FGs in people with high risk factors for cardiovascular disease should not be neglected.

Although incidence of pertussis has been gradually decreased with the introduction of active immunization, total eradication is not possible. This has been shown by national and international data, as well. In the early 2000's, slow increase in incidence of pertussis was observed. To demonstrate the presence of Bordetella pertussis in the Hungarian population by presenting 17 cases of adolescent pertussis. Etiology of pertussis was confirmed by quantification of pertussis-antibodies in blood samples taken from permanently coughing patients in the firstly identified subject's vicinity which latter was explored by retrospective data collection. In the vicinity of the first identified patient epidemiologic research identified another 16 patients all of which were confirmed by serological tests. If permanent coughing is present, pertussis needs to be ruled out. Immunity against pertussis obtained by vaccination fades by the end of childhood. Bordetella pertussis circulates in the national population. A booster-vaccination against pertussis in the regular vaccination course for the 11-year old children is recommended. Pertussis in adolescents and in adults is mild and atypical, but in case of prolonged coughing it needs to be considered.

The role of exercise imaging with thallium-201 in the evaluation of patients suspected of having coronary artery disease was studied in 194 patients undergoing diagnostic coronary arteriography. Ninety-eight patients had 70 percent or more narrowing of one or more coronary vessels and 96 patients had either no or insignificant coronary artery disease. One hundren twenty-three of the 194 patients had conclusive treadmill exercise electrocardiograms (either positive or negative), and 71 had inconclusive exercise electrocardiograms. The specificity of exercise imaging (97 percent) was higher than that of exercise electrocardiograms (86 percent, p less than 0.02). The specificity of both tests combined was not significantly different from that of exercise electrocardiograms alone. The sensitivity (79 percent) and specificity (95 percent) of exercise imaging were not significantly different in patients with inconclusive exercise electrocardiograms when compared with those in patients whose exercise electrocardiograms were conclusive. These data indicate that exercise imaging is sensitive and specific in diagnosing coronary artery disease in the presence of diagnostic as well as nondiagnostic exercise electrocardiograms and that propranolol therapy does not affect the results

Full Text Available Background and Purpose Orthostatic hypotension (OH is known to be present even in patients with early Parkinson’s disease (PD. To affirm the presence of OH and find correlation between OH and other dysautonomic symptoms in PD, this study has done in newly-diagnosed PD patients. Methods Forty-five non-demented patients with no prior history of treatment for PD were recruited (17 men, 63.8 ± 10.1 years of age. All the patients were evaluated for OH before starting medications. Autonomic symptoms were evaluated with structured questionnaires. Clinical characteristics of PD were evaluated (median Hoehn and Yahr stage 2.0 (1–3, 1.3 ± 1.1 years of disease duration, and comorbid medical conditions that could affect blood pressure were also recorded. Results OH was prevalent, and eighteen patients (40% showed orthostatic hypotension, and twenty-seven (60% did not (normotensive group. There was no significant difference in demographic and clinical characteristics between groups. The presence or severity of symptoms of autonomic dysfunction in the OH group also not differed from those of the normotensive group. Conclusions OH was prevalent even in the early stage of PD, and was not related to presence or severity of any other symptoms of autonomic dysfunction. Our findings suggest that clinicians should pay attention to OH from the early stage of disease.

Full Text Available Abstract Background In many studies, some information might not be available for the whole cohort, some covariates, or even the outcome, might be ascertained in selected subsamples. These studies are part of a broad category termed two-phase studies. Common examples include the nested case-control and the case-cohort designs. For two-phase studies, appropriate weighted survival estimates have been derived; however, no estimator of cumulative incidence accounting for competing events has been proposed. This is relevant in the presence of multiple types of events, where estimation of event type specific quantities are needed for evaluating outcome. Methods We develop a non parametric estimator of the cumulative incidence function of events accounting for possible competing events. It handles a general sampling design by weights derived from the sampling probabilities. The variance is derived from the influence function of the subdistribution hazard. Results The proposed method shows good performance in simulations. It is applied to estimate the crude incidence of relapse in childhood acute lymphoblastic leukemia in groups defined by a genotype not available for everyone in a cohort of nearly 2000 patients, where death due to toxicity acted as a competing event. In a second example the aim was to estimate engagement in care of a cohort of HIV patients in resource limited setting, where for some patients the outcome itself was missing due to lost to follow-up. A sampling based approach was used to identify outcome in a subsample of lost patients and to obtain a valid estimate of connection to care. Conclusions A valid estimator for cumulative incidence of events accounting for competing risks under a general sampling design from an infinite target population is derived.

Objective: To compare the severity of carotid artery disease in diabetic and non-diabetic patients undergoing coronary artery bypass grafting. Methods: From January to June 2008, 379 patients undergoing elective coronary artery bypass surgery were preoperatively evaluated for the presence of carotid stenoses by duplex scanning. Patients were divided into two groups, Group I, 156 (41.2%) diabetic patients and Group II, 223 (58.8%) non-diabetic patients. Results: There were 314 (82.8%) males and 65 (17.2%) females with a mean age of 57.2+-9.1 years. In diabetic group there were 125 (80.1%) males and 31 (19.9%) females with a mean age of 56.3+-8.9 years. Left main stem stenosis was present in 59 (37.8%) diabetics and 45 (20.2%) non-diabetics (p 70% stenosis was present in 20 (5.3%) with 13 (8.3%) diabetics and 7 (3.1%) non-diabetics (p<0.025). Stenosis of 50-70% was observed in 30 (7.9%) of which 17 (10.9%) were diabetics and 13 (5.8%) were non-diabetics. Conclusion: Presence of diabetes mellitus is associated with diffuse coronary artery disease and significant carotid artery disease in patients undergoing coronary artery bypass grafting. (author)

Neutrophils Release Metalloproteinases during Adhesion in the Presence of Insulin, but Cathepsin G in the Presence of Glucagon

Directory of Open Access Journals (Sweden)

Natalia V. Fedorova

2018-01-01

Full Text Available In patients with reperfusion after ischemia and early development of diabetes, neutrophils can attach to blood vessel walls and release their aggressive bactericide agents, which damage the vascular walls. Insulin and 17β-estradiol (E2 relieve the vascular complications observed in metabolic disorders. In contrast, glucagon plays an essential role in the pathophysiology of diabetes. We studied the effect of hormones on neutrophil secretion during adhesion to fibronectin. Amino acid analysis revealed that proteins secreted by neutrophils are characterized by a stable amino acid profile enriched with glutamate, leucine, lysine, and arginine. The total amount of secreted proteins defined as the sum of detected amino acids was increased in the presence of insulin and reduced in the presence of glucagon. E2 did not affect the amount of protein secretion. Proteome analysis showed that in the presence of insulin and E2, neutrophils secreted metalloproteinases MMP-9 and MMP-8 playing a key role in modulation of the extracellular matrix. In contrast, glucagon induced the secretion of cathepsin G, a key bactericide protease of neutrophils. Cathepsin G can promote the development of vascular complications because of its proinflammatory activity and ability to stimulate neutrophil adhesion via the proteolysis of surface receptors.

Full Text Available Background: Hypokalemic paralysis is characterized by episodes of acute muscle weakness associated with hypokalemia. In this study, we evaluated the possible etiological factors in patients of hypokalemic paralysis. Materials and Methods: We reviewed the records of 29 patients who were admitted with a diagnosis of hypokalemic paralysis. Modified Guillain-Barre΄ Syndrome disability scale was used to grade the disability. Results: In this study, 15 (51.7% patients had secondary causes of hypokalemic paralysis and 14 patients (42.3% had idiopathic hypokalemic paralysis. Thyrotoxicosis was present in six patients (20.6%, dengue infection in four patients (13.7%, distal renal tubular acidosis in three patients (10.3%, Gitelman syndrome in one patient (3.4%, and Conn′s syndrome in one patient (3.4%. Preceding history of fever and rapid recovery was seen in dengue infection-induced hypokalemic paralysis. Approximately 62% patients had elevated serum creatinine phosphokinase. All patients had recovered completely following potassium supplementation. Patients with secondary causes were older in age, had significantly more disability, lower serum potassium levels, and took longer time to recover. Conclusion: In conclusion, more than half of patients had secondary causes responsible for hypokalemic paralysis. Dengue virus infection was the second leading cause of hypokalemic paralysis, after thyrotoxicosis. Presence of severe disability, severe hypokalemia, and a late disease onset suggested secondary hypokalemic paralysis.

Abstract Laparoscopic sleeve gastrectomy (LSG) is a therapeutic option in severely obese patients. The aim of this study was to evaluate the presence of Helicobacter pylori (HP) gastritis and non-Helicobacter gastritis in the gastrectomy specimens, and its association to other variables. One hundred six sleeve gastrectomy specimens were examined histopathologically for the presence of gastritis and its relation to other factors like ethnicity, glycemic control, and postoperative complications. Twelve patients had HP gastritis, 39 had non-HP gastritis, and 55 had normal mucosa. There was a statistical difference between the Arab and Jewish Israeli patients in our study. Twenty-eight of the Arab patients had HP gastritis and 48% had non-HP gastritis. In the Jewish population 6% had HP gastritis and 34% had non-HP gastritis. The preoperative glycemic control was worse in the gastritis group with a mean HbA1c of 8.344% while in the normal mucosa group the mean HbA1c was 6.55. After operation the glycemic control reverted to normal in most the diabetic patients. There were few postoperative complications however, they were not related to HP. There is a high incidence of gastritis in obese patients. The incidence of gastritis in the Arab population in our study was higher than that in the Jewish population. The glycemic control before surgery was worse in patients with gastritis than in the normal mucosa group. HP bares no risk for postoperative complications after LSG and does not affect weight loss. However a larger cohort of patients must be studied to arrive at conclusive results. PMID:28422853

AIM: To assess the role of contrast-enhanced computed tomography (CT) prospectively in patients with suspected malignant pleural effusions. MATERIALS AND METHODS: Forty consecutive patients referred for the investigation of a suspected malignant pleural effusion had contrast-enhanced thoracic CT, thoracoscopy, thoraco-centesis and pleural biopsy, either percutaneously or at thoracoscopy. Final diagnoses were based on histopathological or cytological analysis (n = 30), autopsy findings (n = 3) or clinical follow-up (n = 7). The pleural surfaces were classified at contrast-enhanced CT as normal or abnormal and, if abnormal, as benign or malignant in appearance using previously established CT criteria for malignant pleural thickening by two observers unaware of the pathological diagnosis. RESULTS: Pleural effusions were malignant in 32 patients and benign in eight patients. Pleural surfaces assessed at CT showed features of malignancy in 27 out of 32 patients with a malignant effusion (sensitivity 84%, specificity 100%). Overall, CT appearances indicated the presence of malignancy in 28 of 32 (87%) patients. All eight patients with benign pleural disease were correctly diagnosed by CT. CONCLUSION: Contrast-enhanced CT is of value in patients with suspected malignant pleural effusions. The previously established criteria for malignant pleural thickening of nodularity, irregularity and pleural thickness >1 cm are reliable in the presence of a pleural effusion. Traill, Z.C. et al.

Whether antithyroid drugs (ATDs), radioiodine (RAI), or thyroidectomy should be favored in such patients...... - independent of extent - do not influence the natural course of GO. RAI can cause de novo development or progression of GO, which is largely preventable with oral steroid prophylaxis. In patients with mild GO, the thyroid treatment is largely independent of GO.

Objective: To evaluate the frequency of recurrence of spontaneous bacterial peritonitis (SBP) in patients with end stage liver disease and the factors responsible for it. Study Design: Descriptive study. Place and Duration of Study: The Aga Khan University Hospital, Karachi, from November 2008 till November 2009. Methodology: Patients with cirrhosis who were admitted at AKUH with diagnosis of SBP during the study period were included. Any episode of SBP after resolution of the first index case of SBP within one year was considered as recurrence. Results: Out of 238 cirrhotic patients, 157 (66%) had single, while 81 (34%) had recurrent episodes of SBP. History of using proton pump inhibitors (PPI) and diuretics was found in 113 (47.5%) and 139 (58.4%) patients respectively. Only 58 (24.4%) patients were on prophylactic antibiotic therapy. Univariate analysis revealed that the female gender (52%), and presence of porto-systemic encephalopathy (PSE, 31%) were statistically significant (p=0.03) among those who had re-current SBP. On multivariate analysis bilirubin level of > 1.0 mg (OR=7.03; 95%CI=1.55-32), protective factor of hepatitis B (OR 0.31; 95%CI=0.13-0.70) and presence of urinary tract infection (UTI) (OR=2.24; 95%CI=0.99-5.09) were significant in patients with recurrent SBP. Conclusion: Recurrent SBP was noticed in 34% patients. Serum bilirubin level of > 1.0 mg, protective factor of HBV and presence of UTI were significant factors present in patients with recurrent SBP.

Full Text Available BACKGROUND: Diarrhea is a major cause of morbidity and mortality among HIV-infected patients worldwide. OBJECTIVE: We sought to determine the frequency of viral gastrointestinal infections among Brazilian HIV-infected patients with diarrhea. METHODS: A collection of 90 fecal specimens from HIV-infected individuals with diarrhea, previously tested for the presence of bacteria and parasite was analyzed by polymerase chain reaction and sequence analysis for the presence of enteric viruses such as astrovirus, norovirus, rotavirus groups A, B and C, adenovirus, herpes simplex virus, Epstein-Barr virus, cytomegalovirus, and human bocavirus. RESULTS: Twenty patients (22.2%; n = 90 were infected with parasites (11 single infections and nine coinfected with virus. Enteropathogenic bacteria were not found. Virus infections were detected in 28.9% (26/90 of the specimens. Cytomegalovirus was the most common virus detected (24.4%; 22/90. Coinfections with viruses and/or parasite were observed in 10 (11.1% samples. CONCLUSION: Gastrointestinal virus infections were more frequent than parasitic or bacterial infections in this patient population.

Objective To assess the frequency and reasons for return to the primary acute care service among leukemia patients undergoing inpatient rehabilitation. Design Retrospective study of all patients with leukemia, myelodysplastic syndrome, aplastic anemia, or myelofibrosis admitted to inpatient rehabilitation at a tertiary referral-based cancer center between January 1, 2005, and April 10, 2012. Items analyzed from patient records included return to the primary acute care service with demographic information, leukemia characteristics, medications, hospital admission characteristics, and laboratory values. Results 225 patients were admitted a total of 255 times. 93/255 (37%) of leukemia inpatient rehabilitation admissions returned to the primary acute care service. 18/93 (19%) and 42/93 (45%) of these patients died in the hospital and were discharged home respectively. Statistically significant factors (p<.05) associated with return to the primary acute care service include peripheral blast percentage and the presence of an antifungal agent on the day of inpatient rehabilitation transfer. Using an additional two factors (platelet count and the presence of an antiviral agent both with a p<.11), a Return To Primary (RTP) - Leukemia index was formulated. Conclusions Leukemia patients with the presence of circulating peripheral blasts and/or antifungal agent may be at increased risk of return to the primary acute care service. The RTP-Leukemia index should be tested in prospective studies to determine its usefulness. PMID:23117267

To investigate the effect of body mass index (BMI) values on 1- and 2-year mortality rates in patients with chronic heart failure (HF). We conducted a retrospective cohort study of 112 patients with confirmed HF who visited the HF outpatient unit of a tertiary hospital of Athens, Greece, during a 5-month period (December 2012 - April 2013). These patients were assigned to four groups based on their BMI category. Data collection was carried out through a review of the medical patient records and the filling in of a structured questionnaire, including information on the demographic and clinical patient variables. Additionally, 1- and 2-year patient mortality was recorded. The statistical significance was two-tailed, and p -values of less than 0.05 were considered significant. The statistical analysis was performed with Mann-Whitney U test, χ 2 test, and Student's t -test using the SPSS software (IBM SPSS 21.0 for Windows). Obese patients had significantly lower 1-year (13% vs 34.6%, p =0.039) and 2-year (4% vs 21.4%, p =0.022) mortality rates compared with those with normal BMI values. Additionally, we found clinically and not statistically significant lower mortality in overweight and obese patients, when compared with normal BMI and overweight patients, respectively. Obesity paradox seems to be present in our study, translating to significantly lower long-term mortality rates of obese patients compared to those with normal BMI. The significantly higher left ventricular ejection fraction and hematocrit levels among obese HF patients could justify our study findings. Further research is needed due to the inherent weaknesses of BMI and the other study limitations.

Establishing consciousness in non-communicative patients: a modern-day version of the Turing test.

2009-03-01

In a recent study of a patient in a persistent vegetative state, [Owen, A. M., Coleman, M. R., Boly, M., Davis, M. H., Laureys, S., & Pickard, J. D. (2006). Detecting awareness in the vegetative state. Science, 313, 1402] claimed that they had demonstrated the presence of consciousness in this patient. This bold conclusion was based on the isomorphy between brain activity in this patient and a set of conscious control subjects, obtained in various imagery tasks. However, establishing consciousness in unresponsive patients is fraught with methodological and conceptual difficulties. The aim of this paper is to demonstrate that the current debate surrounding consciousness in VS patients has parallels in the artificial intelligence (AI) debate as to whether machines can think. Basically, (Owen et al., 2006) used a method analogous to the Turing test to reveal the presence of consciousness, whereas their adversaries adopted a line of reasoning akin to Searle's Chinese room argument. Highlighting the correspondence between these two debates can help to clarify the issues surrounding consciousness in non-communicative agents.

Full Text Available The high recurrence rate remains a major problem that strongly influenced the prognosis of hepatocellular carcinoma (HCC patients who received hepatectomy. The presence of microvascular invasion (MVI is regarded as the most important risk factor that contributes to the postoperative recurrence. Our previous study has hinted that serum microRNA-125b (miR-125b was associated with MVI. The aim of the present study was to identify whether serum miR-125b can serve as a biomarker to reliably predict microvascular invasion (MVI preoperatively. MiR-125b was quantified in 108 HCC patients’ serum before they received surgery by quantitative real-time PCR (qRT-PCR. Our results revealed that MVI was associated with relapse free survival (RFS of postoperative HCC patients; surgical margin width was associated with postoperative RFS in MVI present patients, but not in the patients without MVI. Multivariate analysis revealed that miR-125b, tumor size and AFP were the independent predictive factors associated with MVI in this cohort (P = .001, .001, .003, respectively. The probability of the predictive accuracy of miR-125b was 76.95% (51.32% specificity and 87.50% sensitivity, which was almost equal to the classifier established by combination of AFP and tumor size (78.82% probability, 65.63% specificity and 84.21% sensitivity. Furthermore, the combination of tumor size, AFP and miR-125b yielded a ROC curve area of 86.68% (72.37% specificity and 84.38% sensitivity. Our study indicated that serum miR-125b can be used to predict MVI of HCC patients before they received hepatic resection. Therefore, miR-125b can potentially guide individualized treatment, which helps HCC patients, with or without MVI, to benefit from different surgical approach.

We conducted a randomized controlled trial (RCT) of an early palliative care intervention (ENABLE: Educate, Nurture, Advise, Before Life Ends) for persons with advanced cancer and their family caregivers. Not all patient participants had a caregiver coparticipant; hence, we explored whether there were relationships between patient survival, having an enrolled caregiver, and caregiver outcomes prior to death. One hundred and twenty-three patient-caregiver dyads and 84 patients without a caregiver coparticipant participated in the ENABLE early versus delayed (12 weeks later) RCT. We collected caregiver quality-of-life (QOL), depression, and burden (objective, stress, and demand) measures every 6 weeks for 24 weeks and every 3 months thereafter until the patient's death or study completion. We conducted survival analyses using log-rank and Cox proportional hazards models. Patients with a caregiver coparticipant had significantly shorter survival (Wald = 4.31, HR = 1.52, CI: 1.02-2.25, P = 0.04). After including caregiver status, marital status (married/unmarried), their interaction, and relevant covariates, caregiver status (Wald = 6.25, HR = 2.62, CI: 1.23-5.59, P = 0.01), being married (Wald = 8.79, HR = 2.92, CI: 1.44-5.91, P = 0.003), and their interaction (Wald = 5.18, HR = 0.35, CI: 0.14-0.87, P = 0.02) were significant predictors of lower patient survival. Lower survival in patients with a caregiver was significantly related to higher caregiver demand burden (Wald = 4.87, CI: 1.01-1.20, P = 0.03) but not caregiver QOL, depression, and objective and stress burden. Advanced cancer patients with caregivers enrolled in a clinical trial had lower survival than patients without caregivers; however, this mortality risk was mostly attributable to higher survival by unmarried patients without caregivers. Higher caregiver demand burden was also associated with decreased patient survival. © 2016 The Authors. Cancer Medicine published by

Full Text Available Introduction. The metabolic syndrome (MS affects 21–53% of patients with chronic obstructive pulmonary disease (COPD with a higher prevalence in the early stages of COPD, with results being highly variable between studies. MS may also affect natural course of COPD—number of exacerbations, quality of life and lung function.Aim. To examine the prevalence of MS and its correlation with comorbidities and COPD characteristics in patients with COPD admitted for exacerbation.Material and methods. 152 patients with COPD admitted for exacerbation were studied for presence of MS. All of them were also assessed for vitamin D status and diabetes mellitus type 2 (DM. Data were gathered for smoking status and exacerbations during the last year. All patients completed CAT (COPD assessment test and mMRC (Modified Medical Research Council Dyspnea scale questionnaires and underwent spirometry. Duration of current hospital stay was recorded.Results. 25% of patients have MS. 23.1% of the male and 29.5% of the female patients have MS (p > 0.05. The prevalence of MS in this study is significantly lower when compared to a national representative study (44.6% in subjects over 45 years. 69.1% of all patients and 97.4% from MS patients have arterial hypertension. The presence of MS is associated with significantly worse cough and sleep (1st and 7th CAT questions; p = 0.002 and p = 0.001 respectively and higher total CAT score (p = 0.017. Average BMI is 27.31. None of the patients have MS and BMI <25. There is a correlation between the presence of MS and DM (p = 0.008 and with the number of exacerbations in the last year (p = 0.015. There is no correlation between the presence of MS and the pulmonary function.Conclusion. This study among hospitalized COPD patients finds comparable but relatively low prevalence of MS (25% compared to previously published data (21–53% and lower prevalence compared to general population (44.6%.

Full Text Available Aim. To describe eye injuries in intensive care unit (ICU patients with multitrauma, to study conjunctival microflora in these patients, and to develop etiologically and pathogenically targeted treatment and prevention of wound complications.Materials and methods. Study group included 50 patients (54 eyes with combined mechanical cerebral and eye injury. All patients underwent possible ophthalmological examination (biomicroscopy, ophthalmoscopy and ocular fundus photographing with portative fundus camera, tonometry, cranial CT and MRT, and bacteriological study of conjunctival smears. Results. Modern methods of ophthalmological examination of ICU patients provided correct diagnosis and prediction of wound healing. Eye injury treatment schedule provided maximum possible results in all ICU patients. Hospitalacquired infection results in asymptomatic dissemination of pathogenic microbes on ocular surface. Conclusions. 14-day topical treatment with antimicrobials, steroids, and NSAIDs reduces posttraumatic inflammation caused by mechanical eye injuries in ICU patients. Bacteriological studies of conjunctival smears demonstrate the presence of pathogenic flora in ICU patients. In these patients, the most effective antibacterial agents are third-generation fluoroquinolones.

2004-02-01

Full Text Available Abstract Background Non-organ-specific autoantibodies are found in a considerable number of anti-HCV positive patients. Previous studies investigated the clinical relevance of these antibodies in patients treated with interferon monotherapy, but not combination therapies. Methods Anti-nuclear, anti-smooth muscle, anti-mitochondrial, anti-neutrophil-cytoplasmatic and anti-liver/kidney microsomal antibodies were determined in 78 consecutive anti-HCV positive patients by indirect immunofluorescence. The presence of these antibodies was related to demographic variables and to the outcome of antiviral combination therapy with interferon-α and ribavirin in 65 patients. Results In our study, positivity for autoantibodies was associated with higher alanine aminotransferase levels and higher mean values for HCV-RNA (p Conclusions The absence of non-organ-specific autoantibodies might indicate a significantly higher chance for viral clearance in response to combination therapy for chronic hepatitis C infection. Therefore, despite of an overall higher treatment response, the addition of the immunomodulatory drug ribavirin could accentuate immunological differences that affect treatment outcome and might have been less obvious in earlier studies analysing interferon monotherapy.

Background: The occult hepatitis B infection (OBI) is defined as the presence of hepatitis B virus (HBV) DNA in the sera or in the liver biopsy and the absence of hepatitis B surface antigen (HBsAg) by serological test. Objectives: The current study aimed to evaluate the occult HBV infection by polymerase chain reaction (PCR) and determine HBV genotyping among the patients with abnormal alanine transaminase (ALT) in Ahvaz city, Iran. Patients and Methods: The sera of 120 patients, 54 (45%) females and 66 (55%) males, with abnormal ALT 40-152 IU were collected. All the patients were negative for HBsAg for more than one year. The patients` sera were tested by PCR using primers specified for the S region of HBV. Then the positive PCR products were sequenced to determine HBV genotyping and phylogenic tree. Results: Of these 120 subjects, 12 (10%) patients including 6 (5%) males and 6 (5%) females were found positive for HBV DNA by PCR, which indicated the presence of occult HBV infection among these patients. The sequencing results revealed that genotype D was predominant with sub-genotyping D1 among OBI patients. Conclusions: Occult hepatitis B infection is remarkably prevalent in Ahvaz, Iran, and should be considered as a potential risk factor for the transmission of Hepatitis B Virus throughout the community by the carriers.

Patients generally prefer to have their family present during medical or nursing interventions. Family presence is assumed to reduce anxiety, especially during painful interventions. This study employed a randomized controlled experimental design to determine the effects of family presence on pain and anxiety during invasive nursing procedures. The study population consisted of patients hospitalized in the observation unit of the internal medicine section in the emergency department of a university hospital. The sample comprised 138 patients assigned into the experimental and control groups by drawing lots. The invasive nursing procedure was carried out in the presence of family members, for members of the experimental group, and without family members, for members of the control group. Thus, the effects of family presence on pain and anxiety during the administration of an invasive nursing procedure to patients were analyzed. The results showed that members of the experimental and control groups did not differ with respect to the pain and state anxiety scores during the intervention. Family presence does not influence the participants' pain and anxiety during an invasive nursing procedure. Thus, the decision regarding family presence during such procedures should be based on patient preference. Copyright © 2015 Elsevier Ltd. All rights reserved.

Full Text Available Background/Aim. Multiple sclerosis (MS is an immunemediated disorder of the central nervous system (CNS, characterized by inflammation, demyelination and axonal loss. Retinal periphlebitis (RP is often present in MS patients with similar evolution and histopathological changes as MS lesions. The aim of this study was to analyze the presence of RP in MS patients during different clinical phases, and its connection with impairment of blood-brain barrier. Methods. The study included 45 patients (26 females and 19 males with MS. Their average age was 33.2 ± 8.1 years. There were 28 patients with relapsing-remitting (RR form, 7 with primary progresive (PP and 10 with secondary progressive (SP form of MS. There were 27 patients in the relapse and 18 patients in the remission phase. The average MS duration was 7.48 ± 1.3 years. Ophthalmological, neurological and MRI examination were performed in all the patients, as well as cerebrospinal fluid sampling. Albumin ratio and IgG index were calculated in all the patients. Results. There were 9 patients with RP, and 36 without it. MS duration was significantly longer in the RP group. RP was much more common in the progressive form and was not present in the remission phase of MS. Albumin ratio values were increased in the group with RP. IgG index and IgG synthesis according to Tourtellotte formula, were statistically higher in the group of patients with RP. The values of visual evoked potentials (VEP's latency were significantly higher in the group of patients with RP. Conclusion. The presence of RP is a reliable indicator of MS activity and might be considered as a parameter for monitoring the disease activity and effects of the treatment.

The 5-year survival for patients with resected stage II (N1) non-small cell lung cancer ranges from 40% to 55%. No data exist addressing the benefit of neoadjuvant therapy for patients with stage II disease. This is largely in part due to the lack of a reliable, minimally invasive method to assess hilar nodes. This study is aimed at determining the ability of fusion positron emission/computed tomography (PET/CT) to identify hilar metastases in patients with resected non-small cell lung cancer. A retrospective review of surgically resected patients with fusion PET/CT within 30 days of resection was performed. The sensitivity, specificity, positive predictive value, and negative predictive value for PET/CT in detecting hilar nodal metastases was calculated for a range of maximum standardized uptake values (SUVmax). Hilar nodes from patients with falsely positive PET/CT scans were analyzed for the presence of histoplasmosis. Additionally, the impact of hilar node size greater than 1 centimeter on the calculated values was assessed. There were 119 patients evaluated. The number of lymph nodes resected ranged from 1 to 12 (X=2.98). There was decreased sensitivity and increased specificity with higher SUVmax cutoff values. At the standard SUVmax value of 2.5, the sensitivity and specificity were only 48.5% and 80.2%. The addition of size of hilar node by CT led to a modest improvement in sensitivity at all SUVmax cutoff values. Fusion PET/CT lacks sensitivity and specificity in identifying hilar nodal metastasis in patients with resected non-small cell lung cancer. Further prospective studies assessing the utility of PET/CT versus alternative sampling techniques are warranted. Copyright © 2012 The Society of Thoracic Surgeons. Published by Elsevier Inc.

Objective: To study the changes of serum parathyroid hormone-M, magnesium, and calcium levels and their interrelationships in patients with mild acute pancreatitis (MAP) and severe acute pancreatitis (SAP). Methods: Serum level of PTH-M was measured by means of radioimmunoassay, serum magnesium and calcium levels were determines with automatic biochemical analytical apparatus. Results: 1) Serum levels of PTH-M in acute period and daring recovery in patients with MAP and SAP were not significant different from those in controls (p > 0.05); serum levels of magnesium and calcium in cute period of patients with SAP were significantly lower than those in controls (p<0.01); 2) There was a linear positive correlation between serum levels of PTH-M and serum magnesium in acute-phase of SAP patients, correlation coefficient r = 0.413 (p<0.05). Conclusion: That presence of hypocalcemia in patients with severe acute pancreatitis did not lead to parathyroid hormone-M responsive rise, that might be due to the presence of hypomagnesemia

On estimating probability of presence from use-availability or presence-background data.

Science.gov (United States)

Phillips, Steven J; Elith, Jane

A fundamental ecological modeling task is to estimate the probability that a species is present in (or uses) a site, conditional on environmental variables. For many species, available data consist of "presence" data (locations where the species [or evidence of it] has been observed), together with "background" data, a random sample of available environmental conditions. Recently published papers disagree on whether probability of presence is identifiable from such presence-background data alone. This paper aims to resolve the disagreement, demonstrating that additional information is required. We defined seven simulated species representing various simple shapes of response to environmental variables (constant, linear, convex, unimodal, S-shaped) and ran five logistic model-fitting methods using 1000 presence samples and 10 000 background samples; the simulations were repeated 100 times. The experiment revealed a stark contrast between two groups of methods: those based on a strong assumption that species' true probability of presence exactly matches a given parametric form had highly variable predictions and much larger RMS error than methods that take population prevalence (the fraction of sites in which the species is present) as an additional parameter. For six species, the former group grossly under- or overestimated probability of presence. The cause was not model structure or choice of link function, because all methods were logistic with linear and, where necessary, quadratic terms. Rather, the experiment demonstrates that an estimate of prevalence is not just helpful, but is necessary (except in special cases) for identifying probability of presence. We therefore advise against use of methods that rely on the strong assumption, due to Lele and Keim (recently advocated by Royle et al.) and Lancaster and Imbens. The methods are fragile, and their strong assumption is unlikely to be true in practice. We emphasize, however, that we are not arguing against

Objective: To determine the effect of ptosis on the refractive error in eyes having monocular elevation deficiency Place and Duration of Study: Al-Shifa Trust Eye Hospital, Rawalpindi, from January 2011 to January 2014. Methodology: Visual acuity, refraction, orthoptic assessment and ptosis evaluation of all patients having monocular elevation deficiency (MED) were recorded. Shapiro-Wilk test was used for tests of normality. Median and interquartile range (IQR) was calculated for the data. Non-parametric variables were compared, using the Wilcoxon signed ranks test. P-values of <0.05 were considered significant. Results: A total of of 41 MED patients were assessed during the study period. Best corrected visual acuity (BCVA) and refractive error was compared between the eyes having MED and the unaffected eyes of the same patient. The refractive status of patients having ptosis with MED were also compared with those having MED without ptosis. Astigmatic correction and vision had significant difference between both the eyes of the patients. Vision was significantly different between the two eyes of patients in both the groups having either presence or absence of ptosis (p=0.04 and p < 0.001, respectively). Conclusion: Significant difference in vision and anisoastigmatism was noted between the two eyes of patients with MED in this study. The presence or absence of ptosis affected the vision but did not have a significant effect on the spherical equivalent (SE) and astigmatic correction between both the eyes. (author)

Objetive: Fibromyalgia (FM) is a chronic pain syndrome with unknown etiology, which affects predominantly women. Mitochondrial alteration could have a role in the pathophysilogical mechanisms of inflammatory conditions as FM and periodontitis. The aim of the present study was assay the relationship between both diseases and mitochondrial dysfunction. Patient and Methods: We study the presence of periodontitis in twelve patients diagnosed of FM and mitochondrial dysfunction described. The diagnosis of FM was established according to ACR criteria and clinical symptoms were evaluated using the Fibromyalgia Impact Questionnaire (FIQ) and Beck Depression Inventory (BDI). Results: Only one patients of twelve included and agreed to participate in the study were diagnosed with periodontitis. Conclusions: Pending studies with larger numbers of patients, we can conclude that mitochondrial dysfunction in FM is a itself event not related with periodontitis. Periodontitis could be considered a exclusion criterion in all studies about mitochondrial dysfunction in patients. Key words:Peridontitis, fibromyalgia, mitocondrial dysfunction, oxidative stress.

Full Text Available BACKGROUND The present study is to find out the prevalence of CAD in severe Aortic Stenosis (AS patients undergoing aortic valve replacement and the relation between the conventional risk factors and CAD in them. Calcific aortic stenosis is associated with the same risk factors as coronary artery disease. Studies on calcific aortic stenosis and CAD are rarely reported from India. The aim of the study is to find out the predictive value of angina for presence of CAD in severe aortic stenosis. MATERIALS AND METHODS All cases of isolated severe aortic stenosis undergoing CAG before aortic valve replacement were included in the study. Data regarding various risk factors, symptoms, echocardiographic parameters and angiographic profile were collected. RESULTS Among a total of 94 patients who have undergone aortic valve replacement for severe AS 40 (42.6% had CAD. Risk factors like advanced age, hypertension, diabetes and smoking were more in patients with CAD compared to isolate AS. Mean gradient was more in the AS + CAD group compared with AS group. Presence of angina had a sensitivity of 82.5% and specificity of 51.85% for predicting coexisting CAD. CONCLUSION Among severe aortic stenosis, patients undergoing AVR 42.6% of patients had significant obstructive CAD. The conventional risk factors predict presence of coronary artery disease. Angina has got a fairly good sensitivity, but moderate specificity for CAD.

AIMS: The biological relevance of bone marrow micrometastases (BMM) in colorectal cancer remains unknown. Here, we investigate their nature by examining the impact of the presence of BMM on metastatic disease-free survival in a cohort of patients with this disease. METHODS: Sixty-three consecutive patients undergoing surgery for colorectal cancer of any stage were studied after approval of the study protocol by the local ethics committee and with full individual informed consent. All had bilateral iliac crest bone marrow aspirates prior to operation. Aspirates were then examined for the presence of aberrant cytokeratin-18-positive cells by a blinded observer using both flow cytometric and APAAP immunohistochemical techniques. RESULTS: Mean follow-up after surgery was 4.6 years (range 1.9-6.9) for those without hepatic metastases at diagnosis. Seven of 34 patients with Dukes\\' stage A or B developed metastatic disease after a mean interval of 4.7 years (range 3.8-6.8). However, only 2 of these patients demonstrated BMM at the time of surgery. Nine of 15 patients with Dukes\\' C carcinoma at the time of surgery subsequently developed metastases after a mean interval of 4.4 years (range 1.9-6.9). Again, only two of these patients had BMM detectable initially. In only three of the 14 patients known to have metastases at the time of operation (i.e. Dukes\\'\\'D\\' disease) were BMM found. CONCLUSION: The presence of BMM as detected by this methodology was not predictive of tumour recurrence or metastasis. This study does not support the consideration of adjuvant therapy based on the presence of BMM at a single pre-operative time point in patients with colorectal cancer.

Industrial support of biomedical research may bias scientific conclusions, as demonstrated by recent analyses of pharmaceutical studies. However, this issue has not been systematically examined in the area of nutrition research. The purpose of this study is to characterize financial sponsorship of scientific articles addressing the health effects of three commonly consumed beverages, and to determine how sponsorship affects published conclusions. Medline searches of worldwide literature were used to identify three article types (interventional studies, observational studies, and scientific reviews) about soft drinks, juice, and milk published between 1 January, 1999 and 31 December, 2003. Financial sponsorship and article conclusions were classified by independent groups of coinvestigators. The relationship between sponsorship and conclusions was explored by exact tests and regression analyses, controlling for covariates. 206 articles were included in the study, of which 111 declared financial sponsorship. Of these, 22% had all industry funding, 47% had no industry funding, and 32% had mixed funding. Funding source was significantly related to conclusions when considering all article types (p = 0.037). For interventional studies, the proportion with unfavorable conclusions was 0% for all industry funding versus 37% for no industry funding (p = 0.009). The odds ratio of a favorable versus unfavorable conclusion was 7.61 (95% confidence interval 1.27 to 45.73), comparing articles with all industry funding to no industry funding. Industry funding of nutrition-related scientific articles may bias conclusions in favor of sponsors' products, with potentially significant implications for public health.

Full Text Available OBJECTIVE: To analyze the results of the treatment of transitional cell carcinoma (TCC of the bladder with radical cystectomy and determine which prognostic factors can be utilized as disease-free survival and cancer-specific survival independent variables. MATERIALS AND METHODS: Medical records of 113 patients submitted to radical cystectomy and bilateral iliac lymphadenectomy between 1993 and 2005 were reviewed. The risk factors analyzed were age, sex, pathological stage, tumor grade, presence of carcinoma in situ and the presence of lymph nodes involvement. RESULTS: After a mean follow-up of 31.7 ? 28.5 months, 46 patients (40.7% presented recurrence and 24 patients (21.2% died due to cancer. Only pathological stage and the lymph nodes involvement became independent variables for recurrence and survival. Patients with T4 stage presented 9.6 times the risk of recurrence of the disease when compared with stage T0 patients (p = 0.010 and the patients with lymph node involvement presented 2.5 times the risk of recurrence (p = 0.047 and 3.1 times the risk of death (p = 0.022 when compared to patients without lymph nodes involvement. CONCLUSIONS: Pathological stage and the involvement of lymph nodes represented more important prognostic variables, and in the presence of advanced stage tumors (T3/T4 and involvement of lymph nodes, the institution of adjuvant treatment should be considered.

Full Text Available Background: Researchers have found elevated rates of childhood sexual abuse (CSA in borderline personality disorder (BPD patients. They have also implicated the role of CSA later in BPD. However, there has been a scarcity of studies regarding this in Indian population. Objectives: To profile the occurrence of CSA and its parameters in BPD patients and to document symptomatology of BPD associated with CSA. Materials and Methods: Thirty-six consecutive patients with BPD were administered with a two-staged semi-structured interview by different interviewers with the first stage for collecting sociodemographic details and confirming BPD diagnosis and the second stage for collecting information about CSA. Results: Of 36 BPD patients, 16 (44.44% reported a history of definite CSA. The majority of CSA associated with BPD were having characteristics of onset at 7–12 years, <10 occasions of abuse, perpetrator being a close relative or a close acquaintance and genital type of CSA. Identity disturbances (P = 0.0354, recurrent suicidal/self-harm behavior (P = 0.0177, and stress-related paranoid/dissociative symptoms (P = 0.0177 were significantly associated with the presence of CSA while unstable interpersonal relationships (P = 0.001 were significantly associated with the absence of CSA. Conclusion: Significant proportion of BPD patients reported CSA. The specific symptom profile of BPD patients can be used to predict the presence of CSA in these patients, which has a direct implication in the treatment of these patients.

Full Text Available Abstract Background A new chimerism analysis based on automated interphase fluorescence in situ hybridization (FISH evaluation was established to detect residual cells after allogene sex-mismatched bone marrow or blood stem-cell transplantation. Cells of 58 patients were characterized as disease-associated due to presence of a bcr/abl-gene-fusion or a trisomy 8 and/or a simultaneous hybridization of gonosome-specific centromeric probes. The automatic slide scanning platform Metafer with its module MetaCyte was used to analyse 3,000 cells per sample. Results Overall 454 assays of 58 patients were analyzed. 13 of 58 patients showed residual recipient cells at one stage of more than 4% and 12 of 58 showed residual recipient cells less than 4%, respectively. As to be expected, patients of the latter group were associated with a higher survival rate (48 vs. 34 month. In only two of seven patients with disease-marker positive residual cells between 0.1–1.3% a relapse was observed. Besides, disease-marker negative residual cells were found in two patients without relapse at a rate of 2.8% and 3.3%, respectively. Conclusion The definite origin and meaning of disease-marker negative residual cells is still unclear. Overall, with the presented automatic chimerism analysis of interphase FISH slides, a sensitive method for detection of disease-marker positive residual cells is on hand.

Variable mortality rates have been reported for patients with rheumatic diseases admitted to an intensive care unit (ICU). Due to the absence of appropriate control groups in previous studies, it is not known whether the presence of a rheumatic disease constitutes a risk factor. Moreover, the accuracy of the Acute Physiology and Chronic Health Evaluation II (APACHE II) score for predicting outcome in this group of patients has been questioned. The primary goal of this study was to compare outcome of patients with rheumatic diseases admitted to a medical ICU to those of controls. The records of all patients admitted between 1 April 2003 and 30 June 2014 (n=4020) were screened for the presence of a rheumatic disease during admission (n=138). The diagnosis of a rheumatic disease was by standard criteria for these conditions. An age- and gender-matched control group of patients without a rheumatic disease was extracted from the patient population in the database during the same period (n=831). Mortality in ICU, in hospital and after 180 days did not differ significantly between patients with and without rheumatic diseases. There was no difference in the performance of the APACHE II score for predicting outcome in patients with rheumatic diseases and controls. This score, as well as a requirement for the use of inotropes or vasopressors, accurately predicted hospital mortality in the group of patients with rheumatic diseases. In conclusion, patients with a rheumatic condition admitted to intensive care do not do significantly worse than patients without such a disease.

Femoral access in 100 consecutive subarachnoid hemorrhage patients: the "craniotomy" of endovascular neurosurgery

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.

Adequate linezolid blood concentrations have been shown to be associated with an improved clinical outcome. Our goal was to assess new predictors of inadequate linezolid concentrations often observed in critically ill patients. Fifty-two critically ill patients with severe infections receiving standard dosing of linezolid participated in this prospective observational study. Serum samples (median, 32 per patient) were taken on four consecutive days, and total linezolid concentrations were quantified. Covariates influencing linezolid pharmacokinetics were identified by multivariate analysis and a population pharmacokinetic model. Target attainment (area under the concentration-time curve over 12 h [AUC12]/MIC ratio of >50; MIC = 2 mg/liter) was calculated for both the study patients and a simulated independent patient group (n = 67,000). Target attainment was observed for only 36% of the population on both days 1 and 4. Independent covariates related to significant decreases of linezolid concentrations included higher weight, creatinine clearance rates, and fibrinogen and antithrombin concentrations, lower concentrations of lactate, and the presence of acute respiratory distress syndrome (ARDS). Linezolid clearance was increased in ARDS patients (by 82%) and in patients with elevated fibrinogen or decreased lactate concentrations. In simulated patients, most covariates, including fibrinogen and lactate concentrations and weight, showed quantitatively minor effects on target attainment (difference of ≤9% between the first and fourth quartiles of the respective parameters). In contrast, the presence of ARDS had the strongest influence, with only ≤6% of simulated patients reaching this target. In conclusion, the presence of ARDS was identified as a new and strong predictor of insufficient linezolid concentrations, which might cause treatment failure. Insufficient concentrations might also be a major problem in patients with combined alterations of other covariate

The effectiveness of sugammadex in reversing rocuronium-induced neuromuscular blockade (NMB) in the presence of drugs that may potentiate NMB remains to be fully established. The aim of this post-hoc analysis of data from a Phase III clinical trial (VISTA; NCT00298831) was to investigate the impact of antibiotics on recovery from rocuronium-induced NMB after administration of sugammadex for reversal, and compared the neuromuscular recovery in patients who received antibiotics preoperatively with those who did not. A Phase III, multicenter, open-label study designed to reflect potential use of sugammadex in clinical practice was conducted at 19 sites. Data obtained from patients who received antibiotics were compared with the cohort of patients who underwent the same protocol without antibiotics. Each subject received rocuronium 0.6 mg/kg for muscle relaxation, after which tracheal intubation was performed; patients were also permitted to receive maintenance doses of rocuronium 0.15 mg/kg to maintain the desired level of NMB throughout the operation, as required.. At least 15 min after the last rocuronium dose, patients received sugammadex 4.0 mg/kg for reversal. Neuromuscular monitoring was continued until a train-of-four (TOF) ratio of ≥0.9 was achieved or the anesthetic was discontinued. The presence of antibiotics prior to the administration of sugammadex did not affect the recovery time from rocuronium-induced NMB when sugammadex 4.0 mg/kg was administered at least 15 min after the last dose of rocuronium. In the presence of antibiotics, the geometric mean (95% CI) time from administration of sugammadex 4.0 mg/kg to recovery of the TOF ratio to ≥0.9 was 1.6 (1.4-1.9) min (range: 0.7-10.5 min), compared with 2.0 (1.8-2.3) min (range: 0.7-22.3 min) for patients who did not receive antibiotics. These findings suggest that prophylactic antibiotic use is unlikely to have a major impact on the recovery time from rocuronium-induced NMB with sugammadex

Objective: To assess the outcome and risk factors associated with mortality in patients with acute respiratory failure (ARF). Design: Observational study. Place and Duration of Study: The Aga Khan University Hospital, Karachi, between January 1997 and June 2001. Patients and Methods: All adult patients admitted with a medical cause of acute respiratory failure were reviewed. The primary outcome measure was mortality and secondary outcome measures were factors associated with mortality in ARF. Multiple logistic regression analysis was used to identify the independent risk factors for mortality. Results: A total of 270 patients were admitted with ARF. Hypercapnic respiratory failure was seen in 186 (69%) and hypoxemic in 84 (31%) cases. Pneumonia and COPD exacerbation were the most common underlying causes of ARF. Ventilator support was required in 93 (34.4%) patients. Hospital mortality was 28%. Chronic renal failure, malignancy, hypokalemia, severe acidosis (pH <7.25), septicemia and ARDS independently correlated with mortality. Mortality rate increased sharply (84%) with the presence of three or more risk factors. Conclusion: Acute respiratory failure has a high mortality rate (28%). Development of ARDS or septicemia was associated with high mortality. Presence of more than one risk factor significantly increased the mortality rate. (author)

The structural pathology of Achilles tendon (AT) ruptures resembles tendinopathy, but the causes remain unknown. Recently, a number of diseases were found to be attributed to bacterial infections, resulting in low-grade inflammation and progressive matrix disturbance. The authors speculate that spontaneous AT ruptures may also be influenced by the presence of bacteria. Bacteria are present in ruptured ATs but not in healthy tendons. Cross-sectional study; Level of evidence, 3. Patients with spontaneous AT ruptures and patients undergoing anterior cruciate ligament (ACL) reconstruction were recruited for this study. During AT surgical repair, excised tendinopathic tissue was collected, and healthy tendon samples were obtained as controls from hamstring tendon grafts used in ACL reconstruction. Half of every sample was reserved for DNA extraction and the other half for histology. Polymerase chain reaction (PCR) was conducted using 16S rRNA gene universal primers, and the PCR products were sequenced for the identification of bacterial species. A histological examination was performed to compare tendinopathic changes in the case and control samples. Five of 20 AT rupture samples were positive for the presence of bacterial DNA, while none of the 23 hamstring tendon samples were positive. Sterile operating and experimental conditions and tests on samples, controlling for harvesting and processing procedures, ruled out the chance of postoperative bacterial contamination. The species identified predominantly belonged to the Staphylococcus genus. AT rupture samples exhibited histopathological features characteristic of tendinopathy, and most healthy hamstring tendon samples displayed normal tendon features. There were no apparent differences in histopathology between the bacterial DNA-positive and bacterial DNA-negative AT rupture samples. The authors have demonstrated the presence of bacterial DNA in ruptured AT samples. It may suggest the potential involvement of bacteria

Full Text Available Introduction: Several lines of evidence have suggested an interesting link between gluten ingestion and schizophrenia. For example, increased levels of gliadin and transglutaminase antibodies have been observed in patients with schizophrenia. Methods: To verify these observations we compared the prevalence of gliadin and transglutaminse antibodies, as well as the presence of the HLA alleles, HLA DQA1*0501-DQB1*02 (DQ2 and HLA-DQA1*0301-DQB1*0302 (DQ8, among patients with schizophrenia and healthy controls. A total of 108 patients with schizophrenia and 60 healthy controls were evaluated. Gliadin antibodies were determined by a visual semiquantitative assay and tissue transglutaminase antibodies were determined both by one-step immunochromatografic assay and ELISA. HLA typing was performed by PCR amplification using sequence-specific primers for each allele. Results: We found a strong association between the presence of gliadin antibodies and schizophrenia (OR 3.488; 95% CI, 1.43-8.44. However, tissue transglutaminase antibodies were not detected in either group neither by immunochromatograpic or ELISA. No significant association was found for the DQ2 or DQ8 heterodimer and the disease, but a significant positive association between schizophrenia and HLA alleles DQA1*0301 and DQB1*02 was present (OR = 2.80; 95% CI, 1.27-6.17, and OR = 2.37, 95% CI, 1.24-4.53, respectively. Conclusions: The present study showed that the presence of gliadin antibodies was not correlated with the presence of HLA DQA1*0301 or DQB1*02 alleles within the group of patients with schizophrenia. Our study replicates the findings that anti-gliadin antibodies are associated with schizophrenia but also suggests that the presence of these antibodies and the HLA alleles DQB1*02 and DQA1*0301 are independently associated with susceptibility to schizophrenia.

The data were evaluated for incidents of ketoacidosis by looking for keywords such as diabetic ketoacidosis, ketoacidosis, lactic acidosis, acidosis, and metabolic acidosis. Results were tabulated individually for empagliflozin (n=260 adverse event reports, dapagliflozin (n=520, and canagliflozin (n=2159. Adverse events were categorized according to age, gender, and insulin use.Results: There were 46, 144, and 450 reports of ketoacidosis concerned with the use of empagliflozin, dapagliflozin, and canagliflozin, respectively. The use of SGLT2 inhibitors was not strictly limited to patients with type 2 diabetes but was cut across categories of insulin use, including a total of 172 cases of SGLT2-related ketoacidosis in individuals above the age of 40 who were not on insulin.Conclusion: Further studies should focus to detect pleiotropic effects of SGLT2 inhibitors, particularly with other oral antihyperglycemic drugs or insulin. A review of the literature suggests that patients with type 2 diabetes with low C-peptide level may be at

Conclusion: Patient non-participation in an RCT comparing surgery to no surgery is related to concern about receiving a treatment through chance and the presence of a strong preference for a particular treatment, particularly a non-surgical one. To avoid protracted recruitment periods, investigators can increase the number of study sites and ensure personnel involved have equipoise and are trained to provide a balanced view of both treatment arms.

Purpose: To evaluate the incidence of thyroid disorders and dose distribution to the thyroid in patients treated with radiotherapy for head-and-neck carcinomas. Methods and Materials: A retrospective evaluation of data from 73 patients treated for head-and-neck cancers in our department was performed. Thyroid function was evaluated mainly by the measurement of thyrotropin (thyroid stimulating hormone [TSH]). A retrospective analysis of treatment plans was performed for 57 patients. Percentages of thyroid glandular volume absorbing 10, 30, and 50 Gy (V10, V30, and V50 respectively) were considered for statistical analysis. Results: A majority of patients (61%) had a normal thyroid function whereas 19 patients (26%) had hypothyroidism. Mean thyroid volume was 30.39 cc. Point 3 (located at isthmus) absorbed lower doses compared with other points (p < 0.0001). Median values of V10, V30, and V50 were 92% (range, 57-100%), 75% (range, 28.5-100%), and 35% (range, 3-83%) respectively. Gender was associated with toxicity (presence of any kind of thyroid disorders) (p < 0.05), with females displaying higher levels of TSHr (relative TSH = patient's value/maximum value of the laboratory range) (p = 0.0005) and smaller thyroid volume (p 0.0012) compared with male population. TSHr values were associated with thyroid volume, and the presence of midline shielding block in the anterior field was associated with relative free thyroxine (FT4r = patient's value/maximum value of the laboratory range) values. Conclusions: Gender and thyroid volume seem to play an important role in the occurrence of thyroid toxicity, but further studies on dose-effect relationship for radiotherapy-induced thyroid toxicity are needed

Full Text Available Background. Alkaptonuria, a rare autosomal recessive metabolic disorder caused by deficiency in homogentisate 1,2-dioxygenase activity, leads to accumulation of oxidised homogentisic acid in cartilage and collagenous structures present in all organs and tissues, especially joints and heart, causing a pigmentation called ochronosis. A secondary amyloidosis is associated with AKU. Here we report a study of an aortic valve from an AKU patient. Results. Congo Red birefringence, Th-T fluorescence, and biochemical assays demonstrated the presence of SAA-amyloid deposits in AKU stenotic aortic valve. Light and electron microscopy assessed the colocalization of ochronotic pigment and SAA-amyloid, the presence of calcified areas in the valve. Immunofluorescence detected lipid peroxidation of the tissue and lymphocyte/macrophage infiltration causing inflammation. High SAA plasma levels and proinflammatory cytokines levels comparable to those from rheumatoid arthritis patients were found in AKU patient. Conclusions. SAA-amyloidosis was present in the aortic valve from an AKU patient and colocalized with ochronotic pigment as well as with tissue calcification, lipid oxidation, macrophages infiltration, cell death, and tissue degeneration. A local HGD expression in human cardiac tissue has also been ascertained suggesting a consequent local production of ochronotic pigment in AKU heart.

Background: traumatic axonal injury is characterized by multifocal lesions, consequences of primary, secondary and tertiary damage which is able to cause varying degrees of disability. Objective: to characterize patients with traumatic axonal injury. Methods: a cross-sectional analytical study was conducted from January 2014 to December 2015. The target population was composed of 35 patients over age 18 whose diagnosis was traumatic axonal injury type I and IV of the Marshall computed tomographic (CT) classification. With the data collected from medical records revisions and direct observation, a database was created in SPSS for its processing through univariate and multivariate techniques. Results: male patients between 18 and 30 years old without bad habits prevailed. Most of the patients survived and death was associated with the presence of severe traumatic axonal injury, Marshall computed tomographic (CT) classification degree III, complications and presence of trauma in thorax, abdomen and cervical spine. Conclusions: diagnosis of traumatic axonal injury is based on the clinical radiological correlation based on images from tomography and it is confirmed by Magnetic resonance imaging (MRI). Histological study shows injuries that are not demonstrated in the most advanced radiological studies. Its prevention is the most fundamental base in medical assistance, followed by neurocritical attention oriented by neuromonitoring. (author)

2014-01-01

Full Text Available Background: It has been proposed that hepatitis C virus (HCV antigens are involved in the pathogenesis of psoriasis and may contribute to severity of the disease. Increased expression of the apoptosis-regulating proteins p53 and tTG and decreased levels of bcl-2 in the keratinocytes of the skin of psoriatic patients have been reported. Aim: This study aims to identify the serum levels of apoptosis-regulating proteins in patients with psoriasis and without HCV infection and to study the relation between clinical severity of psoriasis and the presence of HCV infection. Materials and Methods: Disease severity was assessed by psoriasis area severity index score (PASI of 90 patients with psoriasis grouped as mild (n = 30, moderate (n = 30 and severe (n = 30; 20 healthy individuals were used as controls. All groups were subjected for complete history taking, clinical examination, and tests for liver function and HCV infection. The serum levels of apoptosis related proteins: p53, tTG and bcl-2 were estimated by enzyme linked immune sorbent assay (ELISA. Results: There was a statistically significant (P < 0.001 correlation between clinical severity of psoriasis and presence of HCV antibodies and HCV-mRNA. In addition, significantly (P < 0.001 raised serum p53 and tTG, and reduced bcl-2 were observed among HCV-positive patients as compared to HCV-negative patients and control patients. Conclusion: These results conclude that clinical severity of psoriasis is affected by the presence of HCV antibodies and overexpression of apoptotic related proteins. In addition, altered serum levels of apoptosis-regulating proteins could be useful prognostic markers and therapeutic targets of psoriatic disease.

Full Text Available Purpose of the work is a description of critical position of J. Derrida on metaphysics of presence in phenomenological and structuralist discourses. As a philosophical strategy, deconstruction tries to destroy a violent hierarchy of terms, in which one term dominates the other according to its ontological or rational sense. Methodology of research is based on J. Derrida’s strategy of deconstruction, which tries to undermine the basic principles of knowledge and Western philosophy existence, for example, the opposition between nature and culture. In terms of J. Derrida, to deconstruct Western philosophy means to explore the tensions and contradictions in text, which should clarify false reliability of accepted hierarchies. The originality of the work lies in the identification of metaphysic of presence problem in structuralist and phenomenological discourses through the deconstruction project. Deconstruction should show instability of logocentrism, which focuses on repression of writing in terms of thought, truth, reason or logic. Conclusions: J. Derrida’s deconstruction appeared as an attempt to overthrow metaphysics and get focused on the concept of writing, which scope is limited by discourse. Deconstruction of metaphysics of presence is a continuous request of legitimacy of the existing logocentrism, and search of its weaknesses, aporias and contradictions, which make impossible the tradition, centered around mind.

Full Text Available Background. Graves’ disease may have a number of clinical manifestations with varying degrees of activity that may not always run in parallel. Objectives. To study associations between serum levels of TSH-receptor autoantibodies and the three main manifestations of Graves’ disease (hyperthyroidism, goiter, and presence of orbitopathy at the time of diagnosis of hyperthyroidism. Methods. We describe a cohort of 208 patients with newly diagnosed Graves’ hyperthyroidism. Patients were enrolled in a multiphase study of antithyroid drug therapy of Graves’ hyperthyroidism, entitled “Remission Induction and Sustenance in Graves’ Disease (RISG.” Patients were systematically tested for degree of biochemical hyperthyroidism, enlarged thyroid volume by ultrasonography, and the presence of orbitopathy. Results. Positive correlations were found between the levels of TSH-receptor autoantibodies in serum and the three manifestations of Graves’ disease: severeness of hyperthyroidism, presence of enlarged thyroid, and presence of orbitopathy, as well as between the different types of manifestations. Only around half of patients had enlarged thyroid gland at the time of diagnosis of hyperthyroidism, whereas 25–30% had orbitopathy. Conclusions. A positive but rather weak correlation was found between TSH-receptor antibodies in serum and the major clinical manifestation of Graves’ disease. Only half of the patients had an enlarged thyroid gland at the time of diagnosis.

Full Text Available Objective: to estimate the quality of antiaggregants therapy in patients with coronary heart disease in outpatient settings. Materials and methods. The data of the retrospective outpatient RECVAD registry (3690 patients who lived in Ryazan and its Region and had evidence in their outpatient medical records for one of the diagnoses, such as coronary heart disease, hypertension, chronic heart failure, atrial fibrillation, or their concurrence, were used. Forty­nine patients after acute myocardial infarction (AMI and/or percutaneous coro­ nary interventions (PCI with stenting ≤ 1 year before their inclusion in the registry, who were to undergo dual antiaggregant therapy (DAT according to current clinical guidelines (CG, were identified among 427 patients after AMI and/or PCI with coronary angioplasty. Contra­ indications to DAT were simultaneously revealed and a relationship of the use of therapy to their presence was compared. Results. Among the 49 patients who had indications for DAT that was used in 15 (30.6 % cases and that was not in 3 (6.1 % patients in the presence of contraindications, 25 (51.0 % did not receive DAT in the absence of contraindications and 6 (12.3 % patients received the therapy in the presence of contraindications. Conclusion. DAT prescribed by outpatient physicians does not always meet the current CG. There are cases of not using DAT in the presence of obvious indications for DAT and, on the contrary, those of its use in the presence of contraindications.

Full Text Available Background: Elevated mean platelet volume (MPV has been proposed as a risk factor for coronary artery disease (CAD and is associated with poor clinical outcome in acute coronary syndrome (ACS. However, some studies have contradictory findings. Hence, we aimed to evaluate the association of MPV with the presence of coronary collateral vessel (CCV in patients with ACS. Objective: To find MPV value in ACS patients and to find the predictive value of MPV in the spectrum of CAD and to examine whether levels of MPV predict the presence of CCVs. Methods: A total of 180 patients with first ACS were included in the study. MPV was measured. All patients underwent coronary angiography to know disease severity and CCVs. The CCVs are graded according to the Rentrop scoring system and according to coronary angiography results; patients were divided into two groups as Group 1 (poor CCV and Group 2 (good CCV. Results: The MPV was 10.74 ± 2 fl in poor collateral group patients and 11.01 ± 1.7 fl in good collateral group (P = 0.421. The presence of CCV was not significantly associated with high levels of MPV. MPV value did not show any prediction of the spectrum of CAD. Conclusion: MPV on admission was not associated with the development of CCV positively in patients with ACS. Furthermore, it is not associated with a number of vessel involvements.

Full Text Available The aim of the investigation is to carry out comparative evaluation of metabolic and hemodynamic indices in patients with arterial hypertension (AH and renal dysfunction; to study the interrelation between arterial blood pressure level normalization and the presence or lack of microalbuminuria (MAU in the morning urine portion of patients with AH after therapy with antihypertensive preparations (APs of various groups. Methods. 121 persons have been investigated, 91 out — patients of both sexes, aged 33-55, with the diagnosis of arterial hypertension of stage II risk III, who have been taking Perindopril, Telmisartan and Bisoprolol for3 months. The control of arterial pressure level, biochemical analysis of metabolic indices and morning urine portion test for microalbuminuria has been carried out. Results. MAU has been revealed in 17,6% patients, occurring more frequently in men than in women. Microalbuminuria is accompanied by reliable decrease of total and ionized calcium and magnesium concentrations, an increase of potassium level in blood plasma, increase of cholesterol, triglycerides, glucose and levels. Patients with AH and renal dysfunction reliably demonstrate higher levels of systolic and diastolic arterial pressure in the morning and evening hours, their normalization effect after APs intake is significantly interconnected with MAU presence. Conclusion. In patients with AH and MAU the main risk factors of cardio-vascular diseases development are more expressed. Microalbuminuria is a risk factor in patients with arterial hypertension and may influence on the basic blood electrolyte balance. While carrying out antihypertensive therapy the presence of MAU should be taken into consideration

Mutual correction of co-cultivated fibroblasts from patients with Hunter's and Hurler's syndrome could be inhibited by either fructose 1-phosphate or mannose 6-phosphate. In the presence of fructose 1-phosphate a 50% mixture of fibroblasts from a patient with Hunter's syndrome and a normal homozygous individual showed an increased 35 S-sulphate incorporation into acid mucopolysaccharides. When fibroblast cultures from one obligate and two possible carriers of Hunter's syndrome were tested for 35 S-sulphate incorporation, the cultures showed either twice the normal 35 S-sulphate incorporation into acid mucopolysaccharides in the presence of fructose 1-phosphate or an abnormally high incorporation in the presence as well as in the absence of the sugar phosphate.

Purpose: To assess the clinical outcome and prostate-specific antigen (PSA) response and to determine prognostic factors for biochemical disease-free survival in patients treated with external beam radiotherapy following radical prostatectomy without hormonal therapy. Methods and Materials: Forty-eight patients were treated after prostatectomy with radiotherapy between March, 1988 and December, 1993. Seven patients had undetectable PSA ( 2.7. Five-year actuarial biochemical disease-free survival values were 71, 48, and 0%, respectively, for the three groups. Biochemical disease-free survival was not affected by preoperative PSA level, clinical stage, Gleason's score, pathologic stage, surgical margins, presence of undetectable PSA after surgery, surgery to radiation interval, total dose, or presence of clinically suspicious local disease. Based on digital rectal exam, there were no local failures. Conclusion: Biochemical disease-free survival after postprostatectomy radiation is predicted by the PSA at the time of irradiation. Clinical local control is excellent, but distant failure remains a significant problem in this population. The addition of concomitant systemic therapy should be investigated in patients with PSA >2.7

Radiation protection of E. coli strains by cysteamine in the presence of oxygen

1986-01-01

The survival of various E. coli K 12 strains with defects in the rec system have been measured after γ-irradiation in air in the presence (0.1 mol dm -3 ) or in the absence of cysteamine. The results confirm those of Bresler et al. (1978) indicating that the protection by cysteamine in the presence of oxygen is due to an influence on enzymatic repair. The low protection by cysteamine of wild-type cells pretreated with chloramphenicol which prevents protein synthesis, supports the above conclusion. The reason for the absence of a protective effect by OH radical scavenging and H-atom donation is discussed. It is proposed that DNA peroxyl radicals are formed during irradiation in the presence of oxygen and that they are transformed into hydroperoxides by H-atom donation from the intracellular glutathione and the added cysteamine. These hydroperoxides are still dangerous for the cell as indicated by the protective action of glutathione peroxidase observed by Marklund et al. (1984). (author)

To determine whether intrathoracic fat volumes are associated with presence and chronicity of atrial fibrillation (AF) and radiofrequency ablation (RFA) treatment outcome. IRB approval was obtained and patient consent was waived for this HIPAA-compliant retrospective study. 169 patients with AF (75 non-paroxysmal and 94 paroxysmal) and 62 control patients underwent cardiac CT examination. Extrapericardial (EPFV) and epicardial fat volumes (EFV) were measured on CT, the sum of which is the total intrathoracic fat volume. Associations between these three fat volumes and presence and chronicity of AF, and outcome after RFA, were evaluated using logistic regression analysis. EFV was significantly associated with presence [OR 1.01 (95 % CI 1.003-1.03), p = 0.01], chronicity of AF [1.008 (1.001-1.020), p = 0.03] and AF recurrence after RFA [1.009 (1.001-1.01), p = 0.02] after adjustment for age, gender and BMI. Patients with a larger EFV had a shorter time to AF recurrence (p = 0.017) and a higher rate of recurrence (54 % vs 46 %) (p = 0.002) after RFA. EPFV had no significant associations. Increased epicardial fat is associated with the presence and chronicity of AF, a higher probability of AF recurrence after RFA and a shorter AF-free interval. (orig.)

Objective: To study the clinical significance of changes of serum levels of gastrin in patients with chronic eczema or chronic urticaria. Methods: Serum gastrin levels were, 37 patients with chromic urticaria and 43 controls. Results: Serum gastrin levels in patients with chronic exzema (102.95 ± 27.33 ng/L) and patients with chronic urticaria (109.87 ± 33.64 ng/L) were both significantly higher than those in controls (61.72 ± 20.38 ng/L, both P<0.01). Difference between the levels in the two patients groups was not significant. Conclusion: The high gastrin levels in those patients might reflect the presence of helicobacter pylori infections; eradication of which might be helpful for treatment of these chronic dermatologic disorders.

Introduction: The utilization of the post-traumatic stress disorder (PTSD) diagnostic spectrum is currently being debated to categorize psychological adjustment in cancer patients. The aims of this study were to: (1) evaluate the presence of cancer-related traumatic dissociative symptomatology in a sample of cancer patients; (2) examine the correlation of cancer-related dissociation and sociodemographic and medical variables, anxiety, depression, and post-traumatic stress symptomatology; (3) investigate the predictors of cancer-related dissociation. Methods: Ninety-two mixed cancer patients (mean age: 58.94, ds = 10.13) recruited from two hospitals in northern Italy were administered a questionnaire on sociodemographic and medical characteristics, the Karnofsky Scale to measure the level of patient activity and medical care requirements, the Hospital Anxiety and Depression Scale (HADS) to evaluate the presence of anxiety and depression, the Impact of Event Scale Revised (IES-R) to assess the severity of intrusion, avoidance, and hypervigilance, and the Peritraumatic Dissociative Experiences Questionnaire (PDEQ) to quantify the traumatic dissociative symptomatology. Results: 31.5% of participants report a PDEQ score above the cutoff. The results indicated that dissociative symptomatology was positively correlated with HADS scores (HADS-Anxiety: r = 0.476, p dissociative symptomatology. The results converged on a three predictor model revealing that IES-R-Intrusion, IES-R-Avoidance, and IES-R-Hyperarousal accounted for 53.9% of the explained variance. Conclusion: These findings allow us to hypothesize a specific psychological reaction which may be ascribed to the traumatic spectrum within the context of cancer, emphasizing the close relationship between the origin of dissociative constituents which, according to the scientific literature, compose the traumatic experience. Our results have implications for understanding dissociative symptomatology in a cancer

Koh, Myung Je; Lee, In Jae; Kim, Joo-Hee

2016-01-01

Aim: To assess the relationship between imaging features of pulmonary tuberculosis at computed tomography (CT) and adenosine deaminase (ADA) values via pleural fluid analysis in patients with pleural tuberculosis. Materials and methods: This retrospective study enrolled 60 patients who underwent fluid analysis for ADA and chest CT and were diagnosed with tuberculosis by culture or polymerase chain reaction of pleural fluid and sputum. The presence of centrilobular nodules, consolidation, cavitation, and mediastinal lymphadenopathy at CT were evaluated. The relationship between ADA values and the pattern of pulmonary involvement of tuberculosis was analysed. Results: Pulmonary involvement was seen in 42 of the 60 patients. A centrilobular nodular pattern was seen in 37 and consolidation in 22. In 17 patients, both findings were identified. A centrilobular nodular pattern was more common than consolidation or cavitary lesions. When ADA values were high, pulmonary involvement was more frequent (p=0.002). Comparing low and high ADA groups using an obtained cut-off value of 80 IU/l, the high group had more frequent pulmonary involvement (p<0.001). Conclusion: Patients with tuberculous pleurisy who had high ADA values had a higher probability of manifesting pulmonary tuberculosis. High ADA values may help predict contagious pleuroparenchymal tuberculosis. The most common pulmonary involvement of tuberculous pleurisy showed a centrilobular nodular pattern. - Highlights: • To know the relationship of ADA values and pulmonary involvement pattern of pleural tuberculosis. • To help exact diagnosis of pleuroparenchymal tuberculosis in clinical setting. • The imaging findings of pleuroparenchymal tuberculosis.

It has been reported that patients with multiple sclerosis (MS) exhibit lower serum uric acid levels; however, the association between uric acid concentrations and benign MS (BMS) has not been assessed. Hence, the objective of the present study was to determine whether the serum concentrations of uric acid are associated with the presence of BMS. Men and non-pregnant women over 16 years of age with diagnosis of MS were enrolled in a cross-sectional study. Expanded Disability Status Scale score acid were exclusion criteria. According to subtype of disease, the eligible patients were allocated into groups with BMS and other varieties of MS. A logistic regression analysis was conducted in order to evaluate the association between serum concentrations of uric acid and BMS. A total of 106 patients were included, 39 in the group with BMS and 67 in the group with other varieties of MS. The logistic regression analysis adjusted by age, sex, and disease duration showed that increased concentrations of uric acid, indeed within the physiological levels, are significantly associated with the presence of BMS (OR = 2.60; 95% CI: 1.55-4.38, p uric acid, indeed within the physiological range, are likely linked to the presence of BMS.

Aim: To assess the diagnostic accuracy of computed tomography coronary angiography (CTCA) using a combination of high-definition CT (HD-CTCA) and high level of reader experience, with invasive coronary angiography (ICA) as the reference standard, in high-risk patients for the investigation of coronary artery disease (CAD). Materials and methods: Three hundred high-risk patients underwent HD-CTCA and ICA. Independent experts evaluated the images for the presence of significant CAD, defined primarily as the presence of moderate (≥50%) stenosis and secondarily as the presence of severe (≥70%) stenosis in at least one coronary segment, in a blinded fashion. HD-CTCA was compared to ICA as the reference standard. Results: No patients were excluded. Two hundred and six patients (69%) had moderate and 178 (59%) had severe stenosis in at least one vessel at ICA. The sensitivity, specificity, positive predictive value, and negative predictive value were 97.1%, 97.9%, 99% and 93.9% for moderate stenosis, and 98.9%, 93.4%, 95.7% and 98.3%, for severe stenosis, on a per-patient basis. Conclusion: The combination of HD-CTCA and experienced readers applied to a high-risk population, results in high diagnostic accuracy comparable to ICA. Modern generation CT systems in experienced hands might be considered for an expanded role. - Highlights: • Diagnostic accuracy of High-Definition CT Angiography (HD-CTCA) has been assessed. • Invasive Coronary angiography (ICA) is the reference standard. • Diagnostic accuracy of HD-CTCA is comparable to ICA. • Diagnostic accuracy is not affected by coronary calcium or stents. • HD-CTCA provides a non-invasive alternative in high-risk patients.

Graves' disease is an autoimmune hyperthyroidism caused by thyrotropin receptor antibodies (TRAbs). Because Epstein-Barr virus (EBV) persists in B cells and is occasionally reactivated, we hypothesized that EBV contributes to TRAbs production in Graves' disease patients by stimulating the TRAbs-producing B cells. In order for EBV to stimulate antibody-producing cells, EBV must be present in those cells but that have not yet been observed. We examined whether EBV-infected (EBV(+)) B cells with TRAbs on their surface (TRAbs(+)) as membrane immunoglobulin were present in peripheral blood of Graves' disease patients. We analyzed cultured or non-cultured peripheral blood mononuclear cells (PBMCs) from 13 patients and 11 healthy controls by flow-cytometry and confocal laser microscopy, and confirmed all cultured PBMCs from 8 patients really had TRAbs(+) EBV(+) double positive cells. We unexpectedly detected TRAbs(+) cells in all healthy controls, and TRAbs(+) EBV(+) double positive cells in all cultured PBMC from eight healthy controls. The frequency of TRAbs(+) cells in cultured PBMCs was significantly higher in patients than in controls (p = 0.021). In this study, we indicated the presence of EBV-infected B lymphocytes with TRAbs on their surface, a possible player of the production of excessive TRAbs, the causative autoantibody for Graves' disease. This is a basic evidence for our hypothesis that EBV contributes to TRAbs production in Graves' disease patients. Our results further suggest that healthy controls have the potential for TRAbs production. This gives us an important insight into the pathogenesis of Graves' disease.

Purpose: To describe the frequency of glenoid chondral abnormalities in relation to Hill Sachs (HS) lesions in MR arthrograms of patients with anterior shoulder instability versus controls. Such glenoid lesions can directly impact surgical decision-making and approach, and potentially negatively impact outcome if missed. Materials and methods: Retrospective analysis of direct MR shoulder arthrograms in 165 subjects, (101 with anterior instability/64 controls) was performed independently by 2 blinded musculoskeletal radiologists. Outcome measures were the presence of a HS, anterior labral pathology and glenoid chondral injury. Kappa statistic, Pearson Chi-square and Mann–Whitney analysis were employed for analysis. Results: Inter-observer variability for the presence of HS, labral and chondral lesions was 0.964, 0.965 and 0.858 respectively, with intra-observer variability of 1.0, 0.985 and 0.861 for the principle reader. 58% of patients and 8% of controls had HS (p < 0.001). 72% of patients and 25% of controls had anterior labral injury (p < 0.001). 36% of instability patients and 10% controls had glenoid chondral lesions (p < 0.001). 46% of anterior instability patients with HS defects had chondral injury as opposed to 21% of patients without HS defects (p = 0.009). Depth of the HS lesion did not increase the likelihood of a glenoid chondral lesion (p = 0.7335). Conclusion: In the clinical anterior instability cohort, we demonstrated a statistically significant higher number of HS and glenoid chondral lesions than in controls. In anterior instability patients, the presence of a HS lesion confers a statistically significant greater likelihood of having a glenoid chondral lesion when compared to patients with instability and no HS.

Such glenoid lesions can directly impact surgical decision-making and approach, and potentially negatively impact outcome if missed. Materials and methods: Retrospective analysis of direct MR shoulder arthrograms in 165 subjects, (101 with anterior instability/64 controls) was performed independently by 2 blinded musculoskeletal radiologists. Outcome measures were the presence of a HS, anterior labral pathology and glenoid chondral injury. Kappa statistic, Pearson Chi-square and Mann-Whitney analysis were employed for analysis. Results: Inter-observer variability for the presence of HS, labral and chondral lesions was 0.964, 0.965 and 0.858 respectively, with intra-observer variability of 1.0, 0.985 and 0.861 for the principle reader. 58% of patients and 8% of controls had HS (p < 0.001). 72% of patients and 25% of controls had anterior labral injury (p < 0.001). 36% of instability patients and 10% controls had glenoid chondral lesions (p < 0.001). 46% of anterior instability patients with HS defects had chondral injury as opposed to 21% of patients without HS defects (p = 0.009). Depth of the HS lesion did not increase the likelihood of a glenoid chondral lesion (p = 0.7335). Conclusion: In the clinical anterior instability cohort, we demonstrated a statistically significant higher number of HS and glenoid chondral lesions than in controls. In anterior instability patients, the presence of a HS lesion confers a statistically significant greater likelihood of having a glenoid chondral lesion when compared to patients with instability and no HS.

Objective: To evaluate metabolite concentration in the masseter of patients with systemic sclerosis, by analyzing creatine, choline, lipid and lactate levels, and correlating them with the presence of mandibular osteolysis. Materials and methods: The sample included 25 individuals, 15 of them with diagnosis of systemic sclerosis, divided into two groups according to the presence (group I) or absence (group II) of osteolysis, and 10 healthy individuals (group III, control). All of them were submitted to proton magnetic resonance spectroscopy with PRESS sequence and 3D acquisition. Results: Metabolite analysis showed that the creatine and lipid levels were the same for the three groups. Patients in group I presented higher levels of choline when compared with group III. On the other hand, lower lactate levels were observed in groups I and II when compared with the healthy individuals. Creatine/lipid and choline/lactate ratios were the same in the three groups. Conclusion: Lower lactate levels were observed in the patients with systemic sclerosis (groups I and II). Choline levels were increased in the patients with mandibular osteolysis (group I). Creatine/choline, lipid/lactate and choline/lipid ratios were different among the three groups. Further studies are necessary to understand the role played by the masseter in the development of mandibular osteolysis. (author)

Full Text Available Despite modern approaches in molecular biology and genetics, we are still not able to identify the actual cause in more than 50% of all congenital defects. One-half of the unidentified cases is referred to as “multifactorial”. Detailed prenatal investigation of the fetus can discover the presence of congenital abnormality, which can worsen the process of postnatal adaptation. Retrospective analysis of newborns admitted to the Neonatal Department of Intensive Medicine (NDIM in 2012-2016 with the aim to analyze how the process of postnatal adaptation can be changed by the presence of congenital abnormalities of lip and palate. During a five-year period, 13 newborns were admitted to NDIM (2 premature; 11 term newborns. Chromosomal abnormality was confirmed in one patient (Down syndrome and in one patient suspicion of Patau syndrome was found. Twelve newborns had complete cheilognathopalatoschisis. Two premature newborns and two term newborns had perinatal asphyxia. In this group of patients, 33% had respiratory insufficiency without the presence of congenital heart abnormality, 66% had congenital heart abnormality with respiratory insufficiency, and 2 patients had feeding problems. Only one patient had a positive family history. The diagnosis of complete cheilognathopalatoschisis was confirmed prenatally only in 9 patients. We confirmed that clinical consequences of congenital abnormalities of lip and palate depend on the nature, localization and range of abnormalities, as well as on the genetic background and accompanying congenital abnormalities. Prenatal confirmation of the presence of congenital abnormalities has an important influence on the postnatal management of a patient.

Full Text Available OBJECTIVE: Clinical and surgical outcome of patients with subarachnoid hemorrhage (SAH due to ruptured aneurysm were assessed in comparison to pre-operative data and risk factors such as previous medical history, clinical presenting condition, CT findings and site of bleeding. METHODS: We evaluated 100 consecutive patients with aneurysmal SAH. Gender, color, history of hypertension, smoking habit, site and size of aneurysm, admittance and before surgery Hunt Hess scale, need for cerebro-spinal fluid shunt, presence of complications during the surgical procedure, Glasgow Outcome Scale, presence of vasospasm and of rebleeding were assessed and these data matched to outcome. For statistical analysis, we applied the chi-squared test or Fisher's test using the pondered kappa coeficient. Kruskal-Wallis test was used for comparison of continue variables. Tendency of proportion was analyzed through Cochran-Armitage test. Significance level adopted was 5%. RESULTS: Patients studied were mainly white, female, without previous history of hypertension and non-smokers. Upon hospital admittance, grade 2 of Hunt-Hess scale was most frequently observed (34%, while grade 3 of Fisher scale was the most prevalent. Single aneurysms were most frequent at anterior circulation, between 12 and 24 mm. The most frequent Glasgow Outcome Scale observed was 5 (60%. Hunt Hess upon the moment of surgery and presence of complications during surgical procedure showed positive correlation with clinical outcome (p=0.00002 and p=0.001, respectively. Other variables were not significantly correlated to prognosis. Tendency of proportion was observed between Hunt-Hess scale and Fisher scale. CONCLUSION: Among variables such as epidemiological data, previous medical history and presenting conditions of patients with ruptured aneurysms, the Hunt-Hess scale upon the moment of surgery and the presence of surgical adversities are statistically related to degree of disability.

Full Text Available Objective: Hirsutism, similar to men, is the presence of terminal hairs in androgen-to sensitive areas in women. The present report aimed to study etiology and determine the prevalence of the diseases that causes hirsutism in these patients. Methods: In this study, total number of 40 patients who admitted because of hirsutism to Department of Endocrinology and Metabolism clinic was enrolled. Demographic, clinical and laboratory parameters of the patients were evaluated. Results: Result of the study showed that polycystic ovary syndrome is the most common cause of hirsutism. The second most common cause was found as idiopathic hirsutism. Conclusion: By the present study, etiologic factors of hirsutism were examined firstly in our region in which Ethnic and cultural diversity is concentrated. In rare cases like Cushing's syndrome, hyperprolactinemia, non-classic adrenal hyperplasia, androgen-secreting tumors should be considered in the differential diagnosis of hirsutism.

Full Text Available Pain in fibromyalgia (FM is accompanied by a heterogeneous series of other symptoms, which strongly affect patients’ quality of life and interfere with social and work performance. The present study aimed to evaluate the effects of alexithymia on both the physical and the psychosocial components of the health-related quality of life (HRQoL of FM patients, controlling for the concomitant effects of depression, anxiety, and pain. In particular, given the strong interconnection between depression and alexithymia, the relationship between alexithymia and HRQoL as mediated by depressive symptoms was further investigated. Data were collected on a consecutive sample of 205 female patients with a main diagnosis of FM. The results showed that about 26% of the patients showed the presence of alexithymia, as assessed by the Toronto Alexithymia Scale (TAS-20. Clinically relevant levels of depressive and anxiety symptoms were present in 61 and 60% of the patients, respectively. The results of the hierarchical multiple regression analyses showed that pain intensity (PI and depressive symptoms explained the 45% of the variance of the physical component of HRQoL (p < 0.001. Regarding the mental component of HRQoL, depressive and anxiety symptoms, alexithymia, and PI significantly explained 61% of the variance (p < 0.001. The mediation analyses confirmed that alexithymia had a direct effect on the mental component of HRQoL and showed a statistically significant indirect effect on both the physical and the mental components, through the mediation of depressive symptoms. In conclusion, the results of the present study suggested the presence of both a direct and an indirect effect of alexithymia, in particular of the difficulty identifying feeling, on the HRQoL of patients with FM. Indeed, even though the concomitant presence of depressive symptoms is responsible of an indirect effect, alexithymia per se seems to directly contribute to worsen the impact that this

The aim of the present study was to determine the prevalence of COPD in patients with cerebral and/or peripheral artery disease and to assess factors associated with the presence of COPD. Following the diagnosis of cerebral and/or peripheral artery disease by means of duplex sonography, 166 consecutive patients underwent body plethysmography with capillary blood gas analysis. Thereafter, blood tests with determination of different parameters such as lipid profile, inflammatory and coagulation markers were conducted in remaining 136 patients who fulfilled inclusion criteria of the study. Thirty-six out of 136 patients suffered from COPD, mostly in early stages of the disease. Residual volume indicating emphysema was increased (162.9%±55.9% vs 124.5%±37.0%, p<0.05 and diffusion capacity was decreased (55.1%±19.5% vs 75.3%±18.6%, p<0.05 in COPD patients vs non-COPD group. In capillary blood gas analysis, COPD patients had lower partial pressure of oxygen (70.9±11.5 vs 75.2±11.0 mmHg, p<0.05 and higher partial pressure of carbon dioxide (36.8±7.5 vs 34.4±4.4 mmHg, p<0.05 compared with non-COPD individuals. Presence of COPD was associated with predominance of diabetes mellitus, interleukin-8-related systemic neutrophilic inflammation and anemia. In conclusion, COPD is highly prevalent in patients with atherosclerotic artery disease.

authorities, reactor designers, and operators/ licensees perspectives on the various practices used in the regulation of nuclear power plant siting (selection, evaluation and site preparation). This session was also aimed to address issues on sites where a mixture of activities are taking place (e.g., operating units, new construction, decommissioning, etc.) including organisation of the regulators and licensee/engineering organisation, methods, systems, etc. Conclusions: In general workshop participants agreed on the need to regularly have these kind of forums to discuss relevant regulatory issues for new builds. One important aspect of this workshop was the participation of 'New Entrants'. The interaction between NEA member countries with mature nuclear power plants and newcomers was quite important since it gave newcomers the possibility to benefit of mature international practices in order to focus their regulatory oversight and control. NEA members could also benefit from insights the New Entrants discover as they develop or enhance their regulatory controls. In addition technical exchanges associated with construction experience of New Entrants as they begin to license, build and operate NPP could benefit NEA members

Full Text Available Periodontal disease can have significant effects by increasing the circulating levels of TNF-α, therefore its prevention and treatment is important in maintaining the overall health of the body. Objective: The aim of our research was to assess the differences in the salivary concentration of TNF-α between patients with periodontal disease and those free of the disease and to studz whether it can represent an indicator of the evolution of periodontal disease. We also aimed to assess the practical applicability of the method for the determination of this cytokine in the saliva. Materials and methods: Our study included two groups of subjects, the first group consisting in patients diagnosed with periodontal disease, while the control group included subjects free of periodontal disease. TNF-α concentration was determined with the ELISA test for human TNF-α and the results were expressed in pg/ mL. The data were statistically processed with GraphPad software and the statistical nonparametric Mann-Whitney test was applied. Results: We observe nearly double values of the TNF-α salivary level in the group of patients suffering from periodontal disease compared to the subjects free of periodontal disease, which allows us to notice that saliva analysis is a useful and safely enough method for the diagnosis and follow-up in the development of periodontal disease. Conclusion: The salivary level of TNF-α in patients with periodontal disease is not only an indicator of periodontal disease progression, but also a reflection of the pathogen potential that periodontal disease may have on the overall health of the body.

We report the outcomes of patients treated with palliative radiotherapy (pRT) to the primary tumour in the context of well-controlled metastatic disease after initial chemotherapy. Clinical records of 132 patients with metastatic esophago-gastric (OG) cancer treated with palliative chemotherapy (pCT) between January 2009 and June 2013 were reviewed. Ninetyseven patients had responding or stable disease after 3 months of chemotherapy, of whom 53 patients received pRT to the primary tumour after initial chemotherapy in the presence of well-controlled metastatic disease (group A, pCT-RT). The remaining 44 patients were treated with pCT alone (group B, pCT). Treatment-related outcomes were assessed in above groups including time to local progression (TTLP), progression-free and overall survival. The median overall survival for patients treated with pRT after initial chemotherapy (group A) was 23.3 months (95% confidence interval [CI], 17.70 to 28.89 months) and significantly higher than the 14 months (95% CI, 10.91 to 17.08 months) in patients treated with pCT alone (group B) (p < 0.001). The use of pCT-RT was an independent predictor of OS in multivariate analysis. Local recurrence was observed in 12/53 of patients (23%) in group A compared to 16/44 (36%) in group B. The median TTLP was significantly higher in patients after pCT-RT at 17.3 months (5.23 months to 44.50 months) compared to 8.3 months (range, 4.10 to 25.23 months) in patients treated with pCT alone (p=0.006). The possibility of pRT influencing systemic disease in advanced OG cancer has not been reported, and results from the present study present strong arguments for investigation of this therapeutic strategy in a randomized trial.

Full Text Available Background. Atherogenic lipoproteins, such as total cholesterol, LDL cholesterol, oxidized low density lipoprotein, and triglycerides, are associated with progression of retinopathy. Aim. To evaluate the relationship between lipoprotein(a and retinopathy in patients with type 2 diabetes mellitus. Materials and Methods. We enrolled 145 diabetic consecutive patients (82 females, 63 males; mean age 66.8±12 years, mean duration of diabetes 9.4±6.8 years. Presence and severity of retinopathy were evaluated. Serum lipid profile, including Lp(a level, was assessed. Results. High Lp(a levels have been observed in 54 (78.3% subjects and normal levels in 13 (18.85% subjects as regards diabetic patients with retinopathy. Lp(a levels were high in 15 subjects (21.75% and normal in 63 subjects (91.35% as regards patients without retinopathy. Conclusions. Lp(a levels are increased in a significant percentage of patients with retinopathy compared to diabetic patients without retinopathy. The impact of Lp(a levels on diabetic retinopathy needs to be further investigated.

Full Text Available Abstract Background "The feeling of being there" is one possible way to describe the phenomenon of feeling present in a virtual environment and to act as if this environment is real. One brain area, which is hypothesized to be critically involved in modulating this feeling (also called presence is the dorso-lateral prefrontal cortex (dlPFC, an area also associated with the control of impulsive behavior. Methods In our experiment we applied transcranial direct current stimulation (tDCS to the right dlPFC in order to modulate the experience of presence while watching a virtual roller coaster ride. During the ride we also registered electro-dermal activity. Subjects also performed a test measuring impulsiveness and answered a questionnaire about their presence feeling while they were exposed to the virtual roller coaster scenario. Results Application of cathodal tDCS to the right dlPFC while subjects were exposed to a virtual roller coaster scenario modulates the electrodermal response to the virtual reality stimulus. In addition, measures reflecting impulsiveness were also modulated by application of cathodal tDCS to the right dlPFC. Conclusion Modulating the activation with the right dlPFC results in substantial changes in responses of the vegetative nervous system and changed impulsiveness. The effects can be explained by theories discussing the top-down influence of the right dlPFC on the "impulsive system".

Full Text Available Abstract Background Hereditary spastic paraplegia (HSP is a clinically and genetically heterogeneous disorder that can be an autosomal-dominant, autosomal-recessive, or X-linked disease. The most common autosomal-dominant form of the disease derives from mutations in the SPAST gene. Methods The aim of this study was to analyze 49 patients diagnosed with HSP from the Estonian population for sequence variants of the SPAST gene and to describe the associated phenotypes. Healthy control individuals (n = 100 with no family history of HSP were also analyzed. All patient samples were screened using denaturing high performance liquid chromatography (DHPLC and multiplex ligation-dependent probe amplification (MLPA assay. Samples with abnormal DHPLC and MLPA profiles were sequenced, with the same regions sequenced in control samples. Results Sequence variants of SPAST were identified in 19/49 HSP patients (38.8%, twelve among them had pathogenic mutations. Within the latter group there was one sporadic case. Eight patients had pure, and four - complex HSP. The twelve variants were identified: seven pathogenic (c.1174-1G>C, c.1185delA, c.1276C>T, c.1352_1356delGAGAA, c.1378C>A, c.1518_1519insTC, c.1841_1842insA and five non-pathogenic (c.131C>T, c.484G>A, c.685A>G, c.1245+202delG, c.1245+215G>C. Only 2 of these mutations had previously been described (c.131C>T, c.1245+202delG. Three mutations, c.1174-1G>C, c.1276 C>T, c.1378C>A, showed intrafamilial segregation. Conclusion This study identified new variants of the SPAST gene which included benign missense variants and short insertions/deletions. No large rearrangements were found. Based on these data, 7 new pathogenic variants of HSP are associated with clinical phenotypes.

Pyrolysis of coal in the presence of nitric oxide

Berkowitz, N; Dammeyer, W

1956-01-01

Examination of tars obtained by low-temperature carbonization of a subbituminous coal in the presence of NO suggests that NO will both retard thermal decomposition and inhibit secondary polymerization in the tar phase. But both reactions are subject to the condition that NO is present at the start of incipient pyrolysis (they do not occur if NO is admitted to the retorts at a point above the decomposition temperature of the coal), and their extent depends sharply upon the concentration of NO. At comparatively low partial pressure of NO, the dominant reaction is retardation of decomposition; significant modification of the tar, leading to a greater proportion of low-boiling material, is confined to high-partial pressure of NO. Conclusions, after analyzing tar yields and infrared spectra of tar fractions, are that the inhibition of secondary polymerization in the tar phase involves the transient attachment of NO to primary tar molecules, and that the inhibitory effect of NO is essentially temporary. Tars modified by NO do not appear to be more stable than normal tars in the presence of light, and their composition, as determined by infrared spectroscopy, is not perceptibly different.

Full Text Available Due to the significant increase of complications in young patients with mitral valve prolapse detection of this disease is important. Aim. With the aim of studying the features of mitral valve prolapse 135 persons with mitral valve prolapse at the age of 18–25 years were examined. Methods and results. The features of mitral valve prolapsed were studied with echocardiography, electrocardiography, cardiointervalography. It was established that mitral valve prolapse (MVP in young age had different clinical picture. Patients with MVP 1 degree mainly had autonomic instability, and with 2 degree - mostly signs of connective tissue dysplasia. Conclusion. The presence of MVP is associated with abnormalities of the rhythm and conductivity: 1 degree - sinus tachycardia; the 2nd - sinus arrhythmia, signs of left ventricular hypertrophy and impaired repolarization of the myocardium.

Squamous cell carcinoma of kidney is a rare tumour of the many tumours seen in the kidney. It is usually associated with chronic irritation by a foreign body, which is mostly a stag horn calculus. Diagnosis of carcinoma in the presence of stag horn calculus is bizarre as it is seen in only <1% of patients. After imaging in this patient, the lymph nodes were enlarged and showed necrosis, which favoured the diagnosis of tuberculosis in a country where it is endemic. The pathological examination after surgery has amazed us by the presence of squamous cell carcinoma with lymph nodes positive with metastasis to vertebrae as the patient has presented to us with all symptoms of infection like pain and fever, which never made us think about malignancy preoperatively. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

Abstract Background This study investigated the presence of bursitis in the medial compartment of the knee (pes anserine, semimembranosus-tibial collateral ligament, and medial collateral ligament bursa) in osteoarthritis, chondromalacia patella and medial meniscal tears. Patients and methods Radiological findings of 100 patients undergoing magnetic resonance imaging with a preliminary diagnosis of knee pain were retrospectively evaluated by two radiologists. The first radiologist assessed all patients in terms of osteoarthritis, chondromalacia patella and medial meniscal tear. The second radiologist was blinded to these results and assessed the presence of bursitis in all patients. Results Mild osteoarthritis (grade I and II) was determined in 55 patients and severe osteoarthritis (grade III and IV) in 45 cases. At retropatellar cartilage evaluation, 25 patients were assessed as normal, while 29 patients were diagnosed with mild chondromalacia patella (grade I and II) and 46 with severe chondromalacia patella (grade III and IV). Medial meniscus tear was determined in 51 patients. Severe osteoarthritis and chondromalacia patella were positively correlated with meniscal tear (p chondromalacia patella (p = 0.023 and p = 0.479, respectively). Evaluation of lateral compartment bursae revealed lateral collateral ligament bursitis in 2 patients and iliotibial bursitis in 5 patients. Conclusions We observed a greater prevalence of bursitis in the medial compartment of the knee in patients with severe osteoarthritis and medial meniscus tear. PMID:29333118

Impairments on decision-making tasks are routinely reported: evidence points to a particular deficit in learning from and revising behavior following feedback. In addition, patients tend to make hasty decisions when probabilistic judgments are required. This is known as “jumping to conclusions” (JTC and has typically been demonstrated by presenting participants with colored beads drawn from one of two “urns” until they claim to be sure which urn the beads are being drawn from (the proportions of colors vary in each urn. Patients tend to make early decisions on this task, and there is evidence to suggest that a hasty decision-making style might be linked to delusion formation and thus be of clinical relevance. Various accounts have been proposed regarding what underlies this behavior. In this review, we briefly introduce the disorder and the decision-making deficits associated with it. We then explore the evidence for each account of JTC in the context of a wider decision-making deficit and then go on to summarize work exploring JTC in healthy controls using pharmacological manipulations and functional imaging. Finally, we assess whether JTC might have a role in therapy.Keywords: ketamine, decision making, delusions, fMRI, urn task

Methodology: Patients were divided into two groups of 60 each, undergoing laparoscopic cholecystectomy. Group A comprised non-diabetic patients and group B comprised type II diabetic patients. Patients were followed postoperatively upto one month for the development of SSIs. Proportion of patients with surgical site infections or otherwise was compared between the groups using chi-square test with significance of p < 0.05. Results: In group A, 35 patients were above the age of 40 years. In group B, 38 patients were above the age of 40 years. Four patients in group A developed a surgical site infection. Seven patients in group B developed SSIs (p = 0.07). Conclusion: Presence of diabetes mellitus did not significantly affect the onset of surgical site infection in patients undergoing laparoscopic cholecystectomy. (author)

Full Text Available OBJECTIVE: To evaluate the frequency and degree of severity of abnormalities in the auditory pathways in patients with Chiari malformations type I and II. METHOD: This is a series-of-case descriptive study in which the possible presence of auditory pathways abnormalities in 75 patients (48 children and 27 adults with Chiari malformation types I and II were analyzed by means of auditory evoked potentials evaluation. The analysis was based on the determination of intervals among potentials peak values, absolute latency and amplitude ratio among potentials V and I. RESULTS: Among the 75 patients studied, 27 (36% disclosed Arnold-Chiari malformations type I and 48 (64% showed Arnold-Chiari malformations type II. Fifty-three (71% of these patients showed some degree of auditory evoked potential abnormalities. Tests were normal in the remaining 22 (29% patients. CONCLUSION: Auditory evoked potentials testing can be considered a valuable instrument for diagnosis and evaluation of brain stem functional abnormalities in patients with Arnold-Chiari malformations type I and II. The determination of the presence and degree of severity of these abnormalities can be contributory to the prevention of further handicaps in these patients either through physical therapy or by means of precocious corrective surgical intervention.

Full Text Available Abstract Background Determining the presence and extent of co-morbidities is fundamental in assessing patients with chronic respiratory disease, where increased cardiovascular risk, presence of osteoporosis and low muscle mass have been recognised in several disease states. We hypothesised that the systemic consequences are evident in a further group of subjects with COPD due to Alpha-1 Antitrypsin Deficiency (A1ATD, yet are currently under-recognised. Methods We studied 19 patients with PiZZ A1ATD COPD and 20 age, sex and smoking matched controls, all subjects free from known cardiovascular disease. They underwent spirometry, haemodynamic measurements including aortic pulse wave velocity (aPWV, an independent predictor or cardiovascular risk, dual energy X-ray absorptiometry to determine body composition and bone mineral density. Results The aPWV was greater in patients: 9.9(2.1 m/s than controls: 8.5(1.6 m/s, p = 0.03, despite similar mean arterial pressure (MAP. The strongest predictors of aPWV were age, FEV1% predicted and MAP (all p Conclusions Patients with A1ATD related COPD have increased aortic stiffness suggesting increased risk of cardiovascular disease and evidence of occult musculoskeletal changes, all likely to contribute hugely to overall morbidity and mortality.

Full Text Available Background. Portal cavernoma (PC is the most critical condition with risk or variceal hemorrhage in pediatric patients. We retrospectively investigated the patients with PC focusing on the predictors for recurrent variceal bleeding. Methods. Between July 2003 and June 2013, we retrospectively enrolled all consecutive patients admitted to our department with a diagnosis of PC without abdominal malignancy or liver cirrhosis. The primary endpoint of this observational study was recurrent variceal bleeding. Independent predictors of recurrent variceal bleeding were identified using the logistic regression model. Results. A total of 157 patients were enrolled in the study. During the follow-up period, 24 patients exhibited onset of recurrent variceal bleeding. Acute variceal bleeding was subjected to conservative symptomatic treatment and emergency endoscopic sclerotherapy. Surgical procedure selection was based on the severity of vascular dilation and collateral circulation. Multivariate logistic regression analysis demonstrated that the presence of ascites, collateral circulation, and portal venous pressure were independent prognostic factors of recurrent variceal bleeding for patients with portal cavernoma. Conclusions. The presence of ascites, collateral circulation, and portal venous pressure evaluation are important and could predict the postsurgical recurrent variceal bleeding in patients with portal cavernoma.

Full Text Available INTRODUCTION: Thrombocytopenia poses a significant problem in the elderly. Not only are there varied causes, but it is also associated with significant morbidity and mortality. We carried out a study to learn the causes of isolated thrombocytopenia in elderly patients and to correlate the severity of thrombocytopenia and bleeding manifestations with various etiologic factors and comorbidities. METHODS: A total of 108 patients above 50 years of age presenting with isolated thrombocytopenia (platelet counts of <100x109/L with normal hemoglobin and total leukocyte counts were enrolled in the study. Detailed history and clinical examinations were carried out for each patient. Complete blood counts were analyzed by automated cell counter. Peripheral smears were examined in all cases. HbsAg, anti-HCV, and anti-HIV testing by enzyme-linked immunosorbent assay was done in all patients. Wherever clinically indicated, bone marrow aspiration biopsy and cytogenetic studies were done. RESULTS: Out of 108 patients, 102 (94.4% presented with bleeding tendencies. Twenty-nine (26.8% presented with serious (World Health Organization grade 3/4 bleedings. Major findings were immune thrombocytopenic purpura in 79 (73.1%, myelodysplastic syndrome in 7 (6.5%, drug-induced thrombocytopenia in 7 (6.5%, and connective tissue disorder in 4 (3.7% cases. Ten patients presented with intracranial bleedings. Upon logistic regression analysis, comorbidities in the form of essential hypertension and diabetes mellitus were significantly associated with occurrence of intracranial bleeding. There was no correlation of serious bleedings with platelet counts. DISCUSSION AND CONCLUSION: Isolated thrombocytopenia in the elderly is associated with significant morbidity. Diligent clinical and laboratory evaluation is required to elucidate the cause of thrombocytopenia in the elderly. Comorbidities in this population are associated with serious bleedings and not low platelet counts as is

Full Text Available Background. Patients with inflammatory bowel diseases could experience mouth and teeth disorders and alterations in psychological mood. Vice versa, the psychological status may influence the presence of oral diseases. Aim. To evaluate in inflammatory bowel disease patients the prevalence of sleep bruxism and its correlation with the presence of oral diseases, quality of sleep, and psychological disturbances. Methods. Patients were consecutively recruited in our clinic and examined for temporomandibular disorders, dental enamel disorders, sleep bruxism, and recurrent aphthous stomatitis by two dentists. Patients also underwent Pittsburgh Sleep Quality Index and Beck Depression Inventory Scale questionnaires. Results. 47 patients and 46 controls were included. Sleep bruxism and enamel wear disorders were more frequent in Crohn’s disease patients when compared with ulcerative colitis patients and controls (p=0.03 and p=0.02, resp.. Among groups, no differences were noted for enamel hypoplasia, temporomandibular disorders, recurrent aphthous stomatitis, depression, and quality of sleep. We found a positive correlation between bruxism and temporomandibular disorders (Spearman 0.6, p 5 (Spearman 0.3, p<0.005. Conclusion. Bruxism and enamel wear disorders should be routinely searched in Crohn’s disease patients. Moreover, the attention of healthcare givers to sleep disturbances should be addressed to all inflammatory bowel disease patients.

Full Text Available Objective: To identify uterine hysteroscopic findings among patientswith prior cesarean section and whom had post-menstrual bleedingspotting type. Methods: We conducted a descriptive and prospective study between June 2008 and December 2009 involving women admitted to our clinic in Ji-Paraná (RO, Brazil, and who complained of prolonged genital bleeding after menstrual period. A total of 20 women with the simultaneous following characteristics were selected: at least one prior cesarean section, aged between 18 and 45 years, no use of hormonal contraceptives, and no history of uterine surgery that could change the cavity anatomy. All participants underwent a hysteroscopic examination. Results: During hysteroscopy, in 90% of the patients, the presence of a cesarean section scar was observed in the last third of the cervix. This scarring causes an anomaly in the uterine cavity anatomy, characterized by the viewing of an enlargement followed by a retraction of the anterior wall, which affords the presence of a pseudocavity with depth and lumen narrowing in variable degrees. Two patients did not present the pseudocavity. Conclusion: Pseudocavities in cesarean section scar are usually found in hysteroscopic examination of patients with prior cesarean section and abnormal uterine spotting.

To investigate the impact of preoperative hydronephrosis and flank pain on prognosis of patients with upper tract urothelial carcinoma. In total, 472 patients with upper tract urothelial carcinoma managed by radical nephroureterectomy were included from Kaohsiung Medical University Hospital Healthcare System. Clinicopathological data were collected retrospectively for analysis. The significance of hydronephrosis, especially when combined with flank pain, and other relevant factors on overall and cancer-specific survival were evaluated. Of the 472 patients, 292 (62%) had preoperative hydronephrosis and 121 (26%) presented with flank pain. Preoperative hydronephrosis was significantly associated with age, hematuria, flank pain, tumor location, and pathological tumor stage. Concurrent presence of hydronephrosis and flank pain was a significant predictor of non-organ-confined disease (multivariate-adjusted hazard ratio = 2.10, P = 0.025). Kaplan-Meier analysis showed significantly poorer overall and cancer-specific survival in patients with preoperative hydronephrosis (P = 0.005 and P = 0.026, respectively) and in patients with flank pain (P hydronephrosis and flank pain independently predicted adverse outcome (hazard ratio = 1.98, P = 0.016 for overall survival and hazard ratio = 1.87, P = 0.036 for and cancer-specific survival, respectively) in multivariate Cox proportional hazards models. In addition, concurrent presence of hydronephrosis and flank pain was also significantly predictive of worse survival in patient with high grade or muscle-invasive disease. Notably, there was no difference in survival between patients with hydronephrosis but devoid of flank pain and those without hydronephrosis. Concurrent preoperative presence of hydronephrosis and flank pain predicted non-organ-confined status of upper tract urothelial carcinoma. When accompanied with flank pain, hydronephrosis represented an independent predictor for worse outcome in patients with upper tract

The ability of 99 Tc m -methoxyisobutylisonitrile (MIBI) single photon emission tomography (SPET) to detect myocardial ischaemia and necrosis was assessed in 56 patients with clinically recognised ischaemic heart disease (IHD). All underwent coronary angiography (CA) and left ventriculography (LV). SPET images were obtained at rest and at peak exercise 90 min after injection of 99 Tc m -MIBI. The presence of persistent (P) or reversible (R) perfusion defects (PD) was then correlated to the resting and exercise ECG and to the results of CA and LV. Of the 56 patients, 34 had reversible underperfusion (RPD), 46 persistent underperfusion (PPD) and 31 had both. The occurrence of RPD correlated well with the occurrence of exercise-induced ST segment depression and/or angina (27 patients of 34 patients, 79%) and with the presence of significant coronary artery disease (CAD) (33 of 44, 73%). In 45 of 46 patients (98%) PPD corresponded to akinetic or severely hypokinetic segments (LV) usually explored by ECG leads exhibiting diagnostic Q waves (42 of 46 patients, 91%). The scan was normal both at rest and after stress in four of 11 patients with no CAD, and in two of 45 patients with CAD. Finally, an abnormal resting scan was seen in seven of 11 patients with normal coronary arteries, of whom six had regional wall motion abnormalities. In conclusion, MIBI SPET is a highly reliable technique for assessing the presence and location of myocardial ischaemia and necrosis. (Author)

Pulmonary hypertension in patients with Martorell hypertensive leg ulcer: a case control study

Science.gov (United States)

2012-01-01

Background Martorell hypertensive ischemic leg ulcer (Martorell ulcer) is characterized by distinct alterations in the arteriolar wall of subcutaneous vessels, leading to progressive narrowing of the vascular lumen and increase of vascular resistance. These changes are similar to the alterations observed in pulmonary arterioles in patients with chronic pulmonary hypertension (PH). This study was aimed to assess an association between the two disorders. Methods In this case–control study, 14 patients with Martorell ulcer were clinically assessed for the presence of pulmonary hypertension using transthoracic Doppler echocardiography. Data from patients were compared to 28 matched hypertensive controls. Results Systolic pulmonary arterial pressure (sPAP) in patients with Martorell ulcer was significantly higher than in the control group (33.8 ± 16.9 vs 25.3 ± 6.5 mmHg, p = 0.023); the prevalence of pulmonary hypertension was 31% (5/14) in patients and 7% (2/28) in controls (p = 0.031). No differences were seen in left heart size and function between patients and controls. Conclusion This study provides first evidence that subcutaneous arteriolosclerosis, the hallmark of Martorell ulcer, is associated with PH. These findings suggest that patients with Martorell leg ulcer might be at significant risk to develop elevated pulmonary arterial pressure. Patients with leg ulcers who present with dyspnea should be evaluated by echocardiography for the presence of pulmonary hypertension. PMID:22686459

Alem, Leila

Although telepresence and a sense of connectedness with others are frequently mentioned in media space studies, as far as we know, none of these studies report attempts at assessing this critical aspect of user experience. While some attempts have been made to measure presence in virtual reality or augmented reality, (a comprehensive review of existing measures is available in Baren and Ijsselsteijn [2004]), very little work has been reported in measuring presence in video-mediated collaboration systems. Traditional studies of video-mediated collaboration have mostly focused their evaluation on measures of task performance and user satisfaction. Videoconferencing systems can be seen as a type of media space; they rely on technologies of audio, video, and computing put together to create an environment extending the embodied mind. This chapter reports on a set of video-mediated collaboration studies conducted at CSIRO in which different aspects of presence are being investigated. The first study reports the sense of physical presence a specialist doctor experiences when engaged in a remote consultation of a patient using the virtual critical care unit (Alem et al., 2006). The Viccu system is an “always-on” system connecting two hospitals (Li et al., 2006). The presence measure focuses on the extent to which users of videoconferencing systems feel physically present in the remote location. The second study reports the sense of social presence users experience when playing a game of charades with remote partners using a video conference link (Kougianous et al., 2006). In this study the presence measure focuses on the extent to which users feel connected with their remote partners. The third study reports the sense of copresence users experience when building collaboratively a piece of Lego toy (Melo and Alem, 2007). The sense of copresence is the extent to which users feel present with their remote partner. In this final study the sense of copresence is

Full Text Available The risk of premature and progressive occlusive vascular disease is high in chronic uremic patients, and it accounts for more than 40% of the mortality in dialysis patients. End stage renal failure (ESRF patients exhibit elevated plasma homocystein levels, about four fold as much as those in the controls, and it is now considered as a causative factor for increased risk of cardiovascular death among these patients. The aim of this study was to evaluate the relationship of total plasma homocysteine level and echocardiographic abnormalities as a surrogate of cardiac disease outcome in hemodialysis patients. 123 adult patients on maintenance hemodialysis and having echocardiography done during January till November 2006 were enrolled in this cross-sectional study. Plasma homocysteine level was directly related to the presence of aortic regur-gitation r= 0.27 P= 0.009. There were negative correlations between ejection fraction (EF, left ventricular systolic dimension (LV.S (r= - 0.71, P= 0.0001, left ventricular diastolic dimension (LV.D (r= -0.23 p= 0.01 and age (r= - 0.021 P= 0.02. In conclusion we did not find the para-doxical reverse epidemiology in our patients and plasma total homocysteine level was in direct correlation with cardiac risk factors such as left ventricular mass index and aortic regurgitation.

Background. Celiac disease (CD) is a genetically determined immune-mediated disorder in which gluten immunogenic peptides are presented to CD4 T cells by HLA-DQ2.5, DQ8, DQ2.2, and their combinations. Our aim is to establish a risk gradient for celiac disease based on HLA-DQ profile in a brazilian representative population and the relevance of DQ2.2 in celiac disease development. Materials and Methods. 237 celiac patients and 237 controls (both groups with 164 females and 73 males) were included. All samples were tested for the presence of predisposing HLA-DQ alleles using the PCR-SSP method. Results were considered significant when p Disease risk was expressed as 1 : N for each HLA-DQ category described at this study. Results. DQ2.5 and/or DQ8 were detected in 224 celiac patients (94.5%) and 84 controls (35.4%). Eight celiac patients (3.4%) and 38 controls (16%) disclosed only DQ2.2. Even though DQ2.2 (β2/β2 or β2/x) showed a low CD risk of 1 : 251 and 1 : 550, respectively, the genotype DQ2.5/DQ2.2 (β2/β2) showed high CD risk of 1 : 10 (p disease risk gradient ranged from 1 : 3014 to 1 : 7. Conclusion. Our study allowed the determination of a risk gradient for celiac disease development in at-risk population, showing that DQ2.2 variant was relevant when associated with DQ2.5.

Purpose: Sentinel lymph node-positive (SLN+) patients who are unlikely to have 4 or more involved axillary nodes might be treated with less extensive regional nodal radiation. The purpose of this study was to define possible predictors of having 4 or more involved axillary nodes. Methods and Materials: The records of 224 patients with breast cancer and 1 to 3 involved SLNs, who underwent completion axillary dissection without neoadjuvant chemotherapy or hormonal therapy were reviewed. Factors associated with the presence of 4 or more involved axillary nodes (SLNs plus non-SLNs) were evaluated by Pearson chi-square test of association and by simple and multiple logistic-regression analysis. Results: Of 224 patients, 42 had involvement of 4 or more axillary nodes. On univariate analysis, the presence of 4 or more involved axillary nodes was positively associated with increased tumor size, lobular histology, lymphovascular space invasion (LVSI), increased number of involved SLNs, decreased number of uninvolved SLNs, and increased size of SLN metastasis. On multivariate analysis, the presence of 4 or more involved axillary nodes was associated with LVSI, increased number of involved SLNs, increased size of SLN metastasis, and lobular histology. Conclusions: Patients with 1 or more involved SLN, LVSI, or SLN macrometastasis should be treated to the supraclavicular fossa/axillary apex if they do not undergo completion axillary dissection. Other SLN+ patients might be adequately treated with less extensive radiation fields

Full Text Available OBJECTIVE: To assess the incidence of bladder carcinoma infiltrating the prostate and prostate adenocarcinoma in patients undergoing radical cystoprostatectomy due to bladder cancer, as well as to assess if the characteristics of the bladder neoplasia influence the prostatic involvement by this neoplasia. MATERIALS AND METHODS: We retrospectively assessed 60 male patients, who underwent radical cystoprostatectomy between July 1997 and December 2003. Mean age was 66.7 years (40 and 93 years. The product of radical cystoprostatectomies was checked for involvement of urethra and prostate parenchyma by the primary neoplasia, and for the presence of associated prostate adenocarcinoma. Bladder neoplasia characteristics, such as localization, size, multifocality, association with in situ carcinoma and histological grade, were studied in order to assess the possibility of using such characteristics as predictive factors of prostate infiltration by bladder urothelial carcinoma. RESULTS: We observed the presence of 20% of patients with bladder carcinoma infiltrating the prostatic urethra, 23.3% of patients with infiltration of the prostate parenchyma and 28.3% of patients with associate prostate adenocarcinoma, resulting in a total of 55% of patients with prostatic involvement (infiltrative bladder carcinoma and/or adenocarcinoma. We also observed a statistically significant correlation between tumor location in the trigone, the presence of in situ carcinoma and the histological grade of the bladder tumor with prostatic infiltration by the vesical neoplasia. CONCLUSION: The coexistence of prostatic neoplasia in patients operated for bladder neoplasia was frequent in our sample (55%. We observed that the prostatic infiltration by bladder tumors occurs more frequently with tumors located in the trigone, with associated in situ carcinoma and with high histological grade. There was no correlation between neoplastic infiltration of prostate and multifocality

AIM: To determine the age-specific prevalence of breast arterial calcifications in patients with systemic hypertension. METHODS: The mammograms and patient records of 2406 women who underwent screening or diagnostic mammography were reviewed retrospectively. Mammograms were evaluated for the presence of arterial calcification and results were coded. Hypertension was defined as use of anti-hypertensive agents and diabetes was defined as use of oral hypoglycaemic agents or insulin. RESULTS: The prevalence of breast arterial calcification among hypertensives (17.6%) was lower than among diabetics (25.4%). The prevalence in the non-diabetic, non-hypertensive group was lowest (7.3%). The prevalence increased with age in all three groups. The highest prevalence was found in diabetics older than 60 years (81.8%). Breast arterial calcification was not found among women younger than 40 years. CONCLUSION: Breast arterial calcification is associated with hypertension and prevalence increases with age. Breast arterial calcification on mammograms may indicate unsuspected hypertension especially in non-diabetic patients

Background. A systematic comparison of magnetic resonance imaging (MRI) options for glioma diagnosis is lacking. Purpose. To investigate multiple MR-derived image features with respect to diagnostic accuracy in tumor grading and survival prediction in glioma patients. Material and Methods. T1 pre- and post-contrast, T2 and dynamic susceptibility contrast scans of 74 glioma patients with histologically confirmed grade were acquired. For each patient, a set of statistical features was obtained from the parametric maps derived from the original images, in a region-of-interest encompassing the tumor volume. A forward stepwise selection procedure was used to find the best combinations of features for grade prediction with a cross-validated logistic model and survival time prediction with a cox proportional-hazards regression. Results. Presence/absence of enhancement paired with kurtosis of the FM (first moment of the first-pass curve) was the feature combination that best predicted tumor grade (grade II vs. grade III-IV; median AUC 0.96), with the main contribution being due to the first of the features. A lower predictive value (median AUC = 0.82) was obtained when grade IV tumors were excluded. Presence/absence of enhancement alone was the best predictor for survival time, and the regression was significant (P < 0.0001). Conclusion. Presence/absence of enhancement, reflecting transendothelial leakage, was the feature with highest predictive value for grade and survival time in glioma patients

Full Text Available CONTEXT: Stroke is a frequent cause of dysphagia. OBJECTIVE: To evaluate in a tertiary care hospital the prevalence of swallowing dysfunction in stroke patients, to analyze factors associated with the dysfunction and to relate swallowing dysfunction to mortality 3 months after the stroke. METHODS: Clinical evaluation of deglutition was performed in 212 consecutive patients with a medical and radiologic diagnosis of stroke. The occurrence of death was determined 3 months after the stroke. RESULTS: It was observed that 63% of the patients had swallowing dysfunction. The variables gender and specific location of the lesion were not associated with the presence or absence of swallowing dysfunction. The patients with swallowing dysfunction had more frequently a previous stroke, had a stroke in the left hemisphere, motor and/or sensitivity alterations, difficulty in oral comprehension, alteration of oral expression, alteration of the level of consciousness, complications such as fever and pneumonia, high indexes on the Rankin scale, and low indexes on the Barthel scale. These patients had a higher mortality rate. CONCLUSIONS: Swallowing evaluation should be done in all patients with stroke, since swallowing dysfunction is associated with complications and an increased risk of death.

Full Text Available Valeria Nagy1, Lili Takacs1, Zita Steiber1, György Pfliegler2, Andras Berta11Department of Ophthalmology, 2Division of Rare Diseases, University of Debrecen Medical and Health Science Center, Debrecen, HungaryBackground: Retinal artery occlusion (RAO is an ischemic vascular damage of the retina, which frequently leads to sudden, mostly irreversible loss of vision. In this study, blood thrombophilic factors as well as cardiovascular risk factors were investigated for their relevance to this pathology. Thrombophilic risk factors so far not evaluated were included in the study.Patients and methods: 28 RAO patients and 81 matched control subjects were examined. From blood samples, protein C, protein S, antithrombinopathy, and factor V (Leiden mutation (FV, factor II gene polymorphism, factor VIII C level, plasminogen activity, lipoprotein(a and fibrinogen levels, hyperhomocysteinemia and presence of anticardiolipin – antiphospholipid antibodies were investigated. Possibly relevant pathologies such as diabetes mellitus, hypertension, and ischemic heart disease were also registered. Statistical analysis by logistic regression was performed with 95% confidence intervals.Results: In the group of patients with RAO only the incidence of hypertension (OR: 3.33, 95% CI: 1.30–9.70, p = 0.014 as an average risk factor showed significant difference, but thrombophilic factors such as hyperfibrinogenemia (OR: 2.9, 95% CI: 1.29–6.57, p = 0.010 and the presence of FV (Leiden mutation (OR: 3.9, 95% CI: 1.43–10.96, p = 0.008 increased the chances of developing this disease.Conclusions: Our results support the assumption that thrombophilia may contribute to the development of RAO besides vascular damage due to the presence of cardiovascular risk factors. Further studies are needed, however, to justify the possible use of secondary prophylaxis in form of anticoagulant/antiplatelet therapy.Keywords: retinal arterial occlusion, risk factors, thrombophilia

Is it possible to predict the presence of colorectal cancer in a blood test?: a probabilistic approach method

José Manuel Navarro-Rodríguez

Full Text Available Introduction: The assessment of the state of immunosurveillance (the ability of the organism to prevent the development of neoplasias in the blood has prognostic implications of interest in colorectal cancer. We evaluated and quantified a possible predictive character of the disease in a blood test using a mathematical interaction index of several blood parameters. The predictive capacity of the index to detect colorectal cancer was also assessed. Methods: We performed a retrospective case-control study of a comparative analysis of the distribution of blood parameters in 266 patients with colorectal cancer and 266 healthy patients during the period from 2009 to 2013. Results: Statistically significant differences (p < 0.05 were observed between patients with colorectal cancer and the control group in terms of platelet counts, fibrinogen, total leukocytes, neutrophils, systemic immunovigilance indexes (neutrophil to lymphocyte ratio and platelet to lymphocyte ratio, hemoglobin, hematocrit and eosinophil levels. These differences allowed the design of a blood analytical profile that calculates the risk of colorectal cancer. This risk profile can be quantified via a mathematical formula with a probabilistic capacity to identify patients with the highest risk of the presence of colorectal cancer (area under the ROC curve = 0.85. Conclusions: We showed that a colorectal cancer predictive character exists in blood which can be quantified by an interaction index of several blood parameters. The design and development of interaction indexes of blood parameters constitutes an interesting research line for the development and improvement of programs for the screening of colorectal cancer.

Full Text Available Abstract Background Atypical antipsychotics provide better control of the negative and affective symptoms of schizophrenia when compared with conventional neuroleptics; nevertheless, their heightened ability to improve cognitive dysfunction remains a matter of debate. This study aimed to examine the changes in cognition associated with long-term antipsychotic treatment and to evaluate the effect of the type of antipsychotic (conventional versus novel antipsychotic drugs on cognitive performance over time. Methods In this naturalistic study, we used a comprehensive neuropsychological battery of tests to assess a sample of schizophrenia patients taking either conventional (n = 13 or novel antipsychotics (n = 26 at baseline and at two years after. Results Continuous antipsychotic treatment regardless of class was associated with improvement on verbal fluency, executive functions, and visual and verbal memory. Patients taking atypical antipsychotics did not show greater cognitive enhancement over two years than patients taking conventional antipsychotics. Conclusions Although long-term antipsychotic treatment slightly improved cognitive function, the switch from conventional to atypical antipsychotic treatment should not be based exclusively on the presence of these cognitive deficits.

The coastal sites present special features so much by the dominant wind system then by the lower layers of the atmosphere. Two types of experiments were handled on a coastal site in presence of sea breeze. First, vertical atmospheric sounding by radiosounding and by throwing experimental balloons; then the discharge of tracer: the SF6. The first experiment lead us to put in a prominent position the Internal Boundary Layer and the determination of its height. Whereas the second experiment allowed us to estimate the diffusion parameters of the site as well as to obtain interesting conclusions on diffusivity of the environment studied and the influence of certain factors

It pays to be green. A premature conclusion?

It has been claimed that good environmental performance can improve firms' economic performance. However, because of e.g. data limitations, the methods applied in most previous quantitative empirical studies on effects of environmental performance on economic performance of firms suffer from several shortcomings. We discuss these shortcomings and conclude that previously applied methods are unsatisfactory as support for a conclusion that it pays for firms to be green. Then we illustrate the consequences of these shortcomings by performing several regression analyses of the effect of environmental performance on economic performance using a panel data set of Norwegian plants. A pooled regression where observable firm characteristics like e.g. size or industry are controlled for, confirms a positive effect of environmental performance on economic performance. However, the estimated positive effect could be due to omitted unobserved variables like management or technology. When the regression model controls for unobserved plant heterogeneity, the effect is generally no longer statistically significant. Hence, although greener plants tend to perform economically better, the analysis provides little support for the claim that it is because they are greener. These empirical findings further indicate that a conclusion that it pays to be green is premature

Attention deficit hyperactivity disorder and drug addiction rehabilitation patients

Carlos Henrique Ferreira Camargo

Full Text Available ABSTRACT Objective Attention deficit hyperactivity disorder (ADHD is characterized by a persistent pattern of inattention or hyperactivity. This study aimed to investigate the relationship between ADHD and drug dependence. Methods The presence and severity of ADHD and substance use were evaluated through questionnaires in 80 adult patients in therapeutic communities. Results No difference in drug use or dependence prevalence between ADHD and non-ADHD patients was found. However, ADHD patients had lower ages on admission (p = 0.004 and at first contact with cocaine (p = 0.033. In ADHD patients, there was a negative correlation between the age at first use of cannabis and the subsequent severity of cannabis use (p = 0.017 and cocaine use (p = 0.033. Conclusions Though there was no difference in prevalence of drug use among groups, results show that ADHD in patients in therapeutic communities may cause different addiction patterns, such as earlier use of cocaine and admission, and a more severe use of cocaine correlated to earlier contact with cannabis.

Scientists have an ethical responsibility to assist non-scientists to understand their findings and expert opinions before they are used as decision-aids within the criminal justice system. The communication of scientific expert opinion to non-scientist audiences (e.g., police, lawyers, and judges) through expert reports is an important but under-researched issue. Readability statistics were used to assess 111 conclusions from a proficiency test in forensic glass analysis. The conclusions were written using an average of 23 words per sentence, and approximately half of the conclusions were expressed using the active voice. At an average Flesch-Kincaid Grade level of university undergraduate (Grade 13), and Flesch Reading Ease score of difficult (42), the conclusions were written at a level suitable for people with some tertiary education in science, suggesting that the intended non-scientist readers would find them difficult to read. To further analyse the readability of conclusions, descriptive features of text were used: text structure; sentence structure; vocabulary; elaboration; and coherence and unity. Descriptive analysis supported the finding that texts were written at a level difficult for non-scientists to read. Specific aspects of conclusions that may pose difficulties for non-scientists were located. Suggestions are included to assist scientists to write conclusions with increased readability for non-scientist readers, while retaining scientific integrity. In the next stage of research, the readability of expert reports in their entirety is to be explored. Copyright © 2013 Elsevier Ireland Ltd. All rights reserved.

Dineva, S.; Prodanova, K.; Mlachkova, D.

2013-12-01

The presence of a periampullary duodenal diverticulum (PDD) is often observed during upper digestive tract barium meal studies and endoscopic retrograde cholangiopancreatography (ERCP). A few papers reported that the diverticulum had something to do with the incidence of pancreatitis. The aim of this study is to investigate if the presence of duodenal diverticula predisposes to the development of a pancreatic disease. A total 3966 patients who had undergone ERCP were studied retrospectively. They were divided into 2 groups-with and without PDD. Patients with a duodenal diverticula had a higher rate of acute pancreatitis. The duodenal diverticula is a risk factor for acute idiopathic pancreatitis. A multiple logistic regression to obtain adjusted estimate of odds and to identify if a PDD is a predictor of acute or chronic pancreatitis was performed. The software package STATISTICA 10.0 was used for analyzing the real data.

Full Text Available Abstract Background Based on the well-recognized etiological role of human papillomavirus (HPV in cervical, anogenital and oropharyngeal carcinogenesis, a potential role of HPV in colorectal carcinogenesis has been suggested. For that reason, the aim of the present study was to investigate the presence of HPV DNA in colorectal carcinomas (CRC and to study overexpression of p16INK4A as a marker for the presence of an active HPV oncoprotein E7. These findings were correlated with clinical and pathological prognostic factors of CRC. Methods The presence of HPV was assessed using a multiplex PCR system of 10 non-biotinylated primers. The amplified fragments of HPV positive samples were further analyzed by a highly sensitive, broad spectrum SPF10 PCR and subsequently genotyped using reverse hybridization in a line probe assay. P16INK4A protein expression was investigated in a subset of 90 (30 HPV positive and 60 HPV negative CRC samples by immunohistochemistry. Results HPV DNA was found in 14.2% of the CRC samples with HPV16 as the most prevalent type. No significant differences in clinical and pathological variables were found between HPV positive and negative CRCs, except for age. HPV positive patients were significantly younger (p = 0.05. There was no significant correlation between the presence of HPV and overexpression of p16INK4A (p = 0.325. Conclusions In conclusion, the presence of oncogenic HPV DNA in a small cohort of CRC samples may suggest that HPV may be involved in the carcinogenesis of some CRC. However, contrary to what has been observed in head and neck squamous cell cancer and cancer of the uterine cervix, p16INK4A does not seem to be a surrogate marker for an active HPV infection in CRC. Therefore, further functional analyses are necessary to elucidate the role of HPV in CRC.

Full Text Available Abstract Background Rickettsioses are emerging infections in Sri Lanka as shown by the increase in the number of clinically diagnosed rickettsial patients being reported to the Epidemiology Unit, Sri Lanka. However, mapping the disease for the whole island with laboratory confirmed cases has not been previously carried out. Methods 615 samples received from 23 hospital representing 8 provinces were tested using ELISA or IFA methods and clinical data was collected using a validated questionnaire. Results Rash was found among more spotted fever seropositive patients than scrub typhus seropositive patients while the opposite was true for the presence of eschar. Spotted fever and scrub typhus was found in a geographically restricted manner. Consistent temporal patterns were seen for the presentation of patients with rickettsioses in Kandy and Kurunegala districts for 2009 and 2010. Conclusions This study expanded knowledge on the distribution of rickettsioses in Sri Lanka and their clinical profiles which in turn helps in the clinical diagnosis of these infections.

Presence is the essence of professional nursing in the nurse-patient connection. Nursing students have little exposure to strategies fostering presence. This pilot study explored students' perceptions of strategies to encourage presence in the classroom. A three-question survey was distributed to students in the last week of classes. Faculty not teaching that course administered the survey. Four faculty used strategies aimed at encouraging presence. These strategies included starting class with a mindfulness minute, mindful movement, singing bowl, peace and power check in, and a discussion of a current event. Each class used only one strategy consistently through the semester. Participants were undergraduate and graduate students enrolled in one of seven classes taught by these faculty. Overall the students found strategies to be beneficial. In reflecting on the experience with the strategies, four themes emerged: calming/relaxing; focusing/centering; setting aside distractions; and feeling community and connection. These brief strategies were acceptable to most students and were helpful to the students in preparing for class. The response to mindfulness minute was most positive. Further research is needed on the introduction of strategies that help students in the classroom and may also increase presence at the bedside. © The Author(s) 2016.

Deborah Negrão Gonçalo Dias

Full Text Available Abstract Introduction: Fibromyalgia (FM is a chronic pain syndrome characterized by generalized pain. It is known that obese patients have more skeletal muscle pain and physical dysfunction than normal weight patients. Therefore, it is important that the early diagnosis of FM be attained in obese patients. Objective: To determine the prevalence of FM in a group of obese patients with indication of bariatric surgery. Materials and methods: The patients were recruited from the Bariatric Surgery outpatient clinic of Hospital de Clínicas of UFPR (HC-UFPR before being submitted to surgery. Patient assessment consisted in verifying the presence or absence of FM using the 1990 and 2011 ACR criteria, as well as the presence of comorbidities. Results: 98 patients were evaluated, of which 84 were females. The mean age was 42.07 years and the BMI was 45.39. The prevalence of FM was 34% (n = 29 according to the 1990 criteria and 45% (n = 38 according to the 2011 criteria. There was no difference in age, BMI, Epworth score and prevalence of other diseases among patients who met or not the 1990 criteria. Only depression was more common in patients with FM. (24.14% vs. 5.45%. The same findings were seen in patients that met the 2011 criteria. Conclusions: The prevalence of FM in patients with morbid obesity is extremely high. However, BMI does not differ in patients with or without FM. The presence of depression may be a risk factor for the development of FM in these patients.

Perforated Sigmoid Diverticulitis in the Presence of Toxic Epidermal Necrolysis

Full Text Available Even though the incidence of toxic epidermal necrolysis (TEN is low, it is also associated with a high mortality rate. The condition predominantly affects the skin, but may also affect the gastrointestinal tract, dramatically increasing mortality. We present a case of perforated sigmoid diverticulitis in the presence of TEN. The patient was taking medication, known to be a risk factor, and presented an affected total body surface area and temporal development similar to previously reported cases of TEN. Characteristic abdominal symptoms, however, were missing. Gastrointestinal involvement in TEN appears to be a poor prognostic factor; medical staff must therefore be alert to patients with TEN who complain of abdominal discomfort. The exact pathogenesis, however, remains unclear.

Full Text Available Background: Environmental habitat may play a role in clinical disparities of primary hyperparathyroidism (pHPT patients. Aims: To compare preoperative clinical symptoms and associated conditions and surgical findings in patients with pHPT, living in different geographical regions from the Black Sea, Mediterranean and Anatolia regions. Study Design: Retrospective, clinical-based multi-centric study of 694 patients with pHPT. Methods: Patients from 23 centers and 8 different geographical regions were included. Data related to baseline demographics, clinical, pathologic and treatment characteristics of 8 regions were collected and included age, gender, residential data, symptoms, history of fracture, existence of brown tumor, serum total Ca and p levels, serum parathormone (PTH levels, serum 25-OH vitamin D levels, bone mineral density, size of the resected abnormal parathyroid gland(s, histology, as well as the presence of ectopia, presence of dual adenoma, and multiple endocrine neoplasia (MEN- or familial-related disease. Results: The median age was 54. Asymptomatic patient rate was 25%. The median PTH level was 232 pg/mL and serum total Ca was 11.4 mg/dL. Eighty-seven percent of patients had an adenoma and 90% of these had a single adenoma. Hyperplasia was detected in 79 patients and cancer in 9 patients. The median adenoma size was 16 mm. Significant parameters differing between regions were preoperative symptoms, serum Ca and p levels, and adenoma size. All patients from South-East Anatolia were symptomatic, while the lowest p values were reported from East Anatolia and the largest adenoma size, as well as highest Ca levels, were from Bulgaria. Conclusion: Habitat conditions vary between geographical regions. This affects the clinicopathological features of patients with pHPT

Review conclusions by Ernst and Canter regarding spinal manipulation refuted

Directory of Open Access Journals (Sweden)

Evans Roni

2006-08-01

Full Text Available Abstract In the April 2006 issue of the Journal of Royal Society of Medicine, Ernst and Canter authored a review of the most recent systematic reviews on the effectiveness of spinal manipulation for any condition. The authors concluded that, except for back pain, spinal manipulation is not an effective intervention for any condition and, because of potential side effects, cannot be recommended for use at all in clinical practice. Based on a critical appraisal of their review, the authors of this commentary seriously challenge the conclusions by Ernst and Canter, who did not adhere to standard systematic review methodology, thus threatening the validity of their conclusions. There was no systematic assessment of the literature pertaining to the hazards of manipulation, including comparison to other therapies. Hence, their claim that the risks of manipulation outweigh the benefits, and thus spinal manipulation cannot be recommended as treatment for any condition, was not supported by the data analyzed. Their conclusions are misleading and not based on evidence that allow discrediting of a large body of professionals using spinal manipulation.

Butty, Z; Gopwani, J; Mehta, S; Margolin, E

2016-01-01

PurposeCentral venous catheterization (CVC) is estimated to be performed in millions of patients per year. Swan-Ganz catheters used for CVC are most often inserted into the internal jugular vein and during this procedure they may come into contact with the sympathetic chain. This study aims to determine the incidence of Horner's syndrome in patients admitted to intensive care unit that have undergone internal jugular CVC insertion during their admission and to determine whether ultrasonography-assisted insertion has decreased the frequency of this complication.Patients and methodsA total of 100 prospective patients admitted to the ICU were examined for the presence of anisocoria and ptosis after undergoing recent CVC. Presence of Horner's syndrome was confirmed by testing with 0.5% apraclonidine and looking for the reversal of anisocoria.ResultsFrequency of Horner's syndrome after CVC was 2% in a sample of 100 prospectively examined patients.ConclusionHorner's syndrome remains a relatively rare but definitive complication of CVC. ICU physicians should be educated about its existence and prevalence and ophthalmologists should inquire about any history of ICU admission necessitating CVC insertion in any patient presenting with Horner's syndrome.

Background. Magnetic resonance imaging (MRI) is the recommended primary investigation method for metastatic spinal cord compression (MSCC). Initiating treatment before the development of motor deficits is essential to preserve neurological function. However, the relationship between MRI-assessed grades of spinal metastatic disease and neurological status has not been widely investigated. Purpose. To analyze the association between neurological function and MRI-based assessment of the extent of spinal metastases using two different grading systems. Material and Methods. A total of 284 patients admitted to our institution for initial radiotherapy or surgery for symptomatic spinal metastases were included in the study. Motor and sensory deficits were categorized according to the Frankel classification system. Pre-treatment MRI evaluations of the entire spine were scored for the extent of spinal metastases, presence and severity of spinal cord compression, and nerve root compression. Two MRI-based scales were used to evaluate the degree of cord compression and spinal canal narrowing and relate these findings to neurological function. Results. Of the patients included in the study, 28 were non-ambulatory, 49 were ambulatory with minor motor deficits, and 207 had normal motor function. Spinal cord compression was present in all patients with Frankel scores of B or C, 23 of 35 patients with a Frankel score of D (66%), and 48 of 152 patients with a Frankel score of E (32%). The percentage of patients with severe spinal canal narrowing increased with increasing Frankel grades. The grading according to the scales showed a significant association with the symptoms according to the Frankel scale (P < 0.001). Conclusion. In patients with neurological dysfunction, the presence and severity of impairment was associated with the epidural tumor burden. A significant number of patients had radiological spinal cord compression and normal motor function (occult MSCC)

Neurocognitive deficits are relevant for the jumping-to-conclusions bias, but not for delusions: A longitudinal study

Full Text Available Patients with delusions exhibit an increased tendency to arrive at decisions based on very limited evidence (jumping-to-conclusions; JTC, making this reasoning bias relevant for the treatment of delusions. Neurocognitive deficits contribute to JTC, but it is not known whether this has any bearing on the clinical syndrome of delusions. We addressed this question by reanalyzing data from an efficacy study of non-pharmacological interventions as adjunctive treatments in schizophrenia. We investigated the longitudinal associations of cognitive functioning, JTC and delusions in patients with psychotic disorders receiving either a metacognitive intervention addressing reasoning biases (n = 59, or cognitive remediation (n = 58. Both interventions improved JTC; in the cognitive remediation group, tentative evidence suggested that better neurocognitive performance contributed to this improvement. However, JTC gains were associated with delusion improvement only in the metacognitive intervention group, suggesting a content-specific mechanism of action.

Results: In 19 of 29 patients evaluated in the emergency department, related fractures were detected. According to the Roberts criteria, the results were excellent in 6 patients (31.5%, good in 7 patients (36.8%, fair in 5 patients (26%, and poor in 1 patient (5%. Younger age and lack of ligament lesions were associated with good results. Ligament and cartilage lesions, older age and a longer period of immobilization were associated with worse results. Conclusions: The primary goal of surgery is to restore stability to initiate early range of motion, which is the key factor for a successful outcome. The patient's age and the presence of ligament and cartilage injury have prognostic value. Pure dislocation is uncommon, so it is recommended that radiographs are evaluated carefully for associated fractures around the elbow, especially on first presentation in the emergency department.
