    Amiodarone associated thyrotoxicosis (AAT) occurs in approximately 10% of patients treated with this iodine rich drug in areas of mild iodine deficiency. The thyroid radioactive iodine uptake (RAIU) is usually undetectable or very low in iodine-induced thyrotoxicosis. In the present study, 35 patients with AAT were evaluated. Twelve patients had no thyroid abnormalities by physical exam and all had 24-hr RAIU less than or equal to 4%. In contrast, nine of 11 patients with AAT and diffuse goiters and eight of 12 patients with AAT and nodular goiters had RAIU values greater than 8%. In patients with AAT and goiter it appears possible that the thyroid fails to adapt normally to the excess iodide load, resulting in an inappropriately high RAIU in the presence of excess plasma iodine.

    Full Text Available Objective. Primary aldosteronism (PA is associated with inappropriate left ventricular hypertrophy (LVH in relation to a given gender and body size. There is no ideal parameter to predict the presence of LVH or inappropriate LVH in patients with PA. We investigate the performance of 24-hour urinary aldosterone level, plasma renin activity and aldosterone-to-renin ratio on this task. Methods. We performed echocardiography in 106 patients with PA and 31 subjects with essential hypertension (EH in a tertiary teaching hospital. Plasma renin activity, aldosterone concentration, and 24-hour urinary aldosterone level were measured. Results. Only 24-hour urinary aldosterone was correlated with left ventricular mass index (LVMI and excess LVMI among these parameters. The multivariate analysis revealed the urinary aldosterone level as an independent predictor for LVMI and excess LVMI. Analyzing the ability of urinary aldosterone, plasma aldosterone concentration, and plasma aldosterone-to-renin ratio to identify the presence of LVH (ROC AUC = 0.701, 0.568, 0.656, resp. and the presence of inappropriate LV mass index (defined as measured LVMI in predicting LVMI ratio >135% (ROC area under curve = 0.61, 0.43, 0.493, resp. revealed the better performance of 24-hour urinary aldosterone. Conclusions. In conclusion, 24-hour urinary aldosterone level performed better to predict the presence of LVH and inappropriate LVMI in patients with PA.

    The aim of this research was the study of efficiency and endurance antihypertensive therapy on the basis of fixed combination of enalapril and hydrochlorothiazide (HCTZ) and enalapril and HCTZ in combination with amlodipine according to the twenty-four-hour (? day-and-night) monitoring of blood pressure (? 24H BPM) of patients with arterial hypertension (AH) 2-3 severity. The study included 33 patients with 2-3 grade of hypertension (average age--54,40 ± 3.45 years). All patients performed ? 24H BPM before treatment and after 12 weeks of therapy. The combination of enalapril and HCTZ allowed to achieve target levels of blood pressure in 79% of patients, amlodipine additional purpose--in 86% of patients. We found that this therapy has a corrective effect on daily blood pressure profile, significantly reducing the load pressure and blood pressure variability. During treatment with the combination of enalapril and HCTZ combination of enalapril, HCTZ with amlodipine optimal daily profile of blood pressure after 12 weeks of reaching respectively 63.1% and 71.4% of patients. The treatment with combination of enalapril and HCTZ and adding of amlodipine is characterized by good endurance and high adherence to treatment.

    This study investigated the trends in neurocognitive function and behavioral symptoms among patients with attention-deficit/hyperactivity disorder (ADHD) during 24 months of treatment with methylphenidate in a clinical setting. Study participants consisted of 181 ADHD patients with a mean age of 13.4±2.5 years (ages ranged from 8 to 18 years; 151 boys and 30 girls) who were prescribed oral short-acting methylphenidate two or three times daily, with each dose ranging between 0.3 and 1.0 mg/kg. At baseline and 6, 12, 18, and 24 months from baseline, neurocognitive function was assessed using the Test of Variables of Attention (TOVA) on the day the patient was off medication, and behavioral symptoms were evaluated using the Swanson, Nolan, and Pelham Version IV Scale for ADHD (SNAP-IV) parent form, the SNAP-IV teacher form, and the ADHD-Rating Scale (completed by a child psychiatrist). Of the 181 ADHD patients at the initial visit, 103 (56.9%) completed the study. During the 24-month methylphenidate treatment, only the commission errors in TOVA significantly improved; however, the omission errors, response time, response time variability, response sensitivity, and ADHD score did not. The behavioral symptoms of ADHD, observed by various informants, all declined substantially, and were significantly correlated with each other during the long-term follow-up. The severity of teacher ratings was lower than that of parent and psychiatrist ratings. However, the teacher-rated inattention symptoms showed the strongest correlations with TOVA performance. Findings suggest that neurocognitive deficits in ADHD patients, except inhibition ability, might be long lasting in realistic settings. In addition, obtaining behavior profile assessments from multiple informants, especially from teachers, is vital for establishing a complete understanding of ADHD patients.

    Myocardial viability in area at risk of acute myocardial infarction (AMI) after reperfusion therapy may be underestimated by the 24-hour images due to reverse redistribution (r-RD). Subjects were 37 AMI patients in whom Tc-99m pyrophosphate (PYP)/Tl-201 dual-isotope SPECT was positive. The 24-hour delayed scan was performed with only a Tl window. One month later, follow up rest Tl SPECT was performed to evaluate myocardial viability. In early (at PYP/Tl-201 dual-isotope SPECT), 24-hour, and one month follow up Tl studies, Tl uptake in the area of AMI was scored into four grades: 3 as normal to 0 as severely reduced. The scores were evaluated. Among the 37 AMI lesions, there were 16 r-RD, 3 RD, 16 fixed defect (FD) and 2 normal (positive PYP and normal Tl). Mean Tl scores were early; 1.4{+-}1.1, 24-hr; 0.9{+-}0.9 and one month; 1.3{+-}1.1. The 24-hour Tl score was lower than the early and one month Tl scores (p<0.01). Reverse redistribution is frequently observed in an area at risk where PYP SPECT was positive. Nuclear medicine physicians should be aware of the existence of frequent r-RD in Tl scan to avoid the underestimation of myocardial viability in the acute phase after PTCA. (author)

However, its several other metabolic properties are still controversial. Given this background, the aims of the present study are to evaluate the effects of 24-week liraglutide treatment on body composition, appetite, and lipid profile in overweight and obese type 2 diabetes mellitus (T2DM patients. Methods: A cohort study was carried out on overweight and obese T2DM patients with glycosylated hemoglobin A1c equal to 6% (42 mmol/mol-10% (86 mmol/mol, under a 3-month treatment (at least with maximal dose of metformin as stable regime, by adding liraglutide at doses up to 3 mg/d. Body composition markers were measured by dual-energy X-ray densitometry at baseline and after 24 weeks of liraglutide treatment. Glucose control was monitored by glucose, glycosylated hemoglobin A1c, insulin, and homeostasis model assessment. Finally, the appetite sensation and plasma lipids were also evaluated. Results: Twenty-eight subjects (male/female: 16/12, mean age: 58.75±9.33 years, body mass index: 34.13±5.46 kg/m2 were evaluated.

    Chronic granulomatous disease is an inherited disorder in which phagocytes lack a functional NADPH oxidase and cannot produce superoxide anions. The most common form is caused by mutations in CYBB encoding gp91phox. We investigated 24 CGD patients and their families. Twenty-one mutations in CYBB were classified as X91(0), X91(+) or X91(-) variants according to cytochrome b (558) expression. Point mutations in encoding regions represented 50 % of the mutations found in CYBB, splice site mutations 27 %, deletions and insertions 23 %. Eight mutations in CYBB were novel leading to X91(0)CGD cases. Two of these were point mutations: c493G>T and a double mutation c625C>G in exon 6 and c1510C>T in exon 12 leading to a premature stop codon at Gly165 in gp91phox and missense mutations His209Arg/Thr503Ile respectively. Two novel splice mutations in 5'intronic regions of introns 1 and 6 were found. A novel deletion/insertion c1024_1026delCTG/insT results in a frameshift introducing a stop codon at position 346 in gp91phox. The last novel mutation was the insertion of a T at c1373 leading to a frameshift and a premature stop codon at position 484 in gp91phox. For the first time the precise size of two large mutations in CYBB was determined by array-comparative genomic hybridization and carriers' status were evaluated by multiplex ligation-dependent probe amplification assay. No clear correlation between clinical severity and CYBB mutations could be established. Of three mutations in CYBA, NCF1 and NCF2 leading to rare autosomal recessive CGD, one nonsense mutation c29G>A in exon 1 of NCF2 was new.

    Full Text Available BACKGROUND: Evidence suggests that high-dose statin pretreatment may reduce the risk of periprocedural myocardial infarction (PMI and major adverse cardiac events (MACE for certain patients; however, previous analyses have not considered patients with a history of statin maintenance treatment. In this meta-analysis of randomized controlled trials (RCTs, we reevaluated the efficacy of short-term high-dose statin pretreatment to prevent PMI and MACE in an expanded set of patients undergoing elective percutaneous coronary intervention. METHODS: We searched the PubMed/Medline database for RCTs that compared high-dose statin pretreatment with no statin or low-dose statin pretreatment as a prevention of PMI and MACE. We evaluated the incidence of PMI and MACE, including death, spontaneous myocardial infarction, and target vessel revascularization at the longest follow-up for each study for subgroups stratified by disease classification and prior low-dose statin treatment. RESULTS: Twenty-four RCTs with a total of 5,526 patients were identified. High-dose statin pretreatment was associated with 59% relative reduction in PMI (odds ratio [OR]: 0.41; 95% confidence interval [CI]: 0.34-0.49; P<0.00001 and 39% relative reduction in MACE (OR: 0.61; 95% CI: 0.45-0.83; P = 0.002. The benefit of high-dose statin pretreatment on MACE was significant for statin-naive patients (OR: 0.69; 95% CI: 0.50-0.95; P = 0.02 and prior low dose statin-treated patients (OR: 0.28; 95% CI: 0.12-0.65; P = 0.003; and for patients with acute coronary syndrome (OR: 0.52; 95% CI: 0.34-0.79; P = 0.003, but not for patients with stable angina (OR: 0.71; 95% CI 0.45-1.10; P = 0.12. Long-term effects on survival were less obvious. CONCLUSIONS: High-dose statin pretreatment can result in a significant reduction in PMI and MACE for patients undergoing elective PCI. The positive effect of high-dose statin pretreatment on PMI and MACE is significant for statin-naïve patients and patients

    Recent studies on clinical chorioamnionitis at term suggest that some patients with this diagnosis have neither intraamniotic infection nor intraamniotic inflammation. A false-positive diagnosis of clinical chorioamnionitis in preterm gestation may lead to unwarranted preterm delivery. We sought to determine the frequency of intraamniotic inflammation and microbiologically proven amniotic fluid infection in patients with preterm clinical chorioamnionitis. Amniocentesis was performed in singleton pregnant women with preterm clinical chorioamnionitis (23 ng/mL. Nonparametric and survival techniques were used for analysis. Among patients with preterm clinical chorioamnionitis, 24% (12/50) had neither microbiologic evidence of intraamniotic infection nor intraamniotic inflammation. Microbial invasion of the amniotic cavity was present in 34% (18/53) and intraamniotic inflammation in 76% (38/50) of patients. The most common microorganisms isolated from the amniotic cavity were the Ureaplasma species. Finally, patients without microbial invasion of the amniotic cavity or intraamniotic inflammation had significantly lower rates of adverse outcomes (including lower gestational age at delivery, a shorter amniocentesis-to-delivery interval, acute histologic chorioamnionitis, acute funisitis, and significant neonatal morbidity) than those with microbial invasion of the amniotic cavity and/or intraamniotic inflammation. Among patients with preterm clinical chorioamnionitis, 24% had no evidence of either intraamniotic infection or intraamniotic inflammation, and 66% had negative amniotic fluid cultures, using standard microbiologic techniques. These observations call for a reexamination of the criteria used to diagnose preterm clinical chorioamnionitis. Copyright © 2017 Elsevier Inc. All rights reserved.

    Full Text Available Gastroesophageal reflux (GER disorder was studied in children and adolescents with chronic and/or recurrent rhinosinusitis not associated with bronchial asthma. Ten children with a clinical and radiological diagnosis of chronic and/or recurrent rhinosinusitis, consecutively attended at the Pediatric Otolaryngology Outpatient Clinic, Federal University of São Paulo, were evaluated. Prolonged esophageal pH monitoring was used to investigate GER disorder. The mean age of the ten patients evaluated (eight males was 7.4 ± 2.4 years. Two patients presented vomiting as a clinical manifestation and one patient presented retrosternal pain with a burning sensation. Twenty-four-hour esophageal pH monitoring was performed using the Sandhill apparatus. An antimony probe electrode was placed in the lower third of the esophagus, confirmed by fluoroscopy and later by a chest X-ray. The parameters analyzed by esophageal pH monitoring included: total percent time of the presence of acid esophageal pH, i.e., pH below 4 (<4.2%; total number of acid episodes (<50 episodes; number of reflux episodes longer than 5 min (3 or less, and duration of the longest reflux episode (<9.2 min. One patient (1/10, 10% presented a 24-h esophageal pH profile compatible with GER disorder. This data suggest that an association between chronic rhinosinusitis not associated with bronchial asthma and GER disorder may exist in children and adolescents, especially in those with compatible GER disorder symptoms. In these cases, 24-h esophageal pH monitoring should be performed before indicating surgery, since the present data suggest that 10% of chronic rhinosinusitis surgeries can be eliminated.

    oscillometry. The device avoids some of the pitfalls of conventional office or clinic blood pressure monitoring (CBPM) using a cuff and mercury sphygmomanometer such as observer bias (the phenomenon of measurement error when the observer overemphasizes expected results) and white coat hypertension (the phenomenon of elevated BP when measured in the office or clinic but normal BP when measured outside of the medical setting). Research Questions Is there a difference in patient outcome and treatment protocol using 24-hour ABPM versus CBPM for uncomplicated hypertension? Is there a difference between the 2 technologies when white coat hypertension is taken into account? What is the cost-effectiveness and budget impact of 24-hour ABPM versus CBPM for uncomplicated hypertension? Research Methods Literature Search Search Strategy A literature search was performed on August 4, 2011 using OVID MEDLINE, MEDLINE In-Process and Other Non-Indexed Citations, EMBASE, the Cumulative Index to Nursing and Allied Health Literature (CINAHL), the Cochrane Library, and the International Agency for Health Technology Assessment (INAHTA) for studies published from January 1, 1997 to August 4, 2011. Abstracts were reviewed by a single reviewer. For those studies meeting the eligibility criteria, full-text articles were obtained. Reference lists were also examined for any additional relevant studies not identified through the search. Articles with unknown eligibility were reviewed with a second clinical epidemiologist and then a group of epidemiologists until consensus was established. The quality of evidence was assessed as high, moderate, low, or very low according to GRADE methodology. Inclusion Criteria English language articles; published between January 1, 1997 and August 4, 2011; adults aged 18 years of age or older; journal articles reporting on the effectiveness, cost-effectiveness, or safety for the comparison of interest; clearly described study design and methods; health technology

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

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

    Atrial premature complexes have been reported to be the most common arrhythmia in cattle and is suspected to be secondary to systemic disease, especially gastrointestinal disease. In order to properly identify pathologic arrhythmia in cattle, the normal rhythm and arrhythmia prevalence should be defined. The objective of this study was to determine the normal heart rate, rhythm, number of ventricular premature complexes (VPCs), and atrial premature complexes (APCs) in unrestrained Angus steers. Twenty-seven client owned steers with unremarkable physical examinations and serum biochemical analyses were used. Twenty-four hour Holter monitors, attached by a custom-made harness, were retrospectively evaluated. Three lead electrocardiographic registrations of good quality and normal sinus rhythm were obtained from all steers in the study. The mean heart rate was 66.8 bpm ± 16.4 bpm. Ventricular premature complexes were rare (noted in 14.8% of steers), and APCs were common (noted in 85% of the steers). Simple second degree AV block was observed in 18.5% of the steers. In summary, healthy steers have rare single VPCs, although it is possible for an individual animal to have apparent more frequent VPCs. Mean heart rate varies with a diurnal pattern similar to other species. Atrial premature complexes are the most prevalent abnormality observed in feedlot steers. Copyright © 2016 Elsevier B.V.

    A novel paper-based Nanoceria Reducing Antioxidant Capacity (NanoCerac) assay for antioxidant detection (Sharpe, Frasco, Andreescu, & Andreescu, 2012), has been adapted for the first time as a high-throughput method, in order to measure the effect of brewing conditions and re-infusion on the antioxidant capacity of twenty-four commercial green teas. The oxygen radical absorbance capacity (ORAC) assay, frequently applied to complex foods and beverages, was used as a comparator measure of antioxidant capacity. A novel measure of sustained antioxidant capacity, the total inherent antioxidant capacity (TI-NanoCerac and TI-ORAC) was measured by infusing each tea six times. Effects of brewing conditions (temperature, brew time, etc.) were assessed using one popular tea as a standard. Both NanoCerac and ORAC assays correlated moderately (R(2) 0.80 ± 0.19). The average first-brew NanoCerac, TI-NanoCerac, first-brew ORAC and TI-ORAC were: 0.73 ± 0.1 GAE/g tea; 2.4 ± 0.70 mmolGAE/g tea; 1.0 ± 0.3 mmolTE/g tea and 2.1 ± 0.71 mmolTE/g tea respectively. Brewing conditions including water temperature and infusion time significantly affected antioxidant capacity. The high-throughput adaptation of the original NanoCerac assay tested here offered advantages over ORAC, including portability and rapid analysis.

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

    Full Text Available Abstract Background Malignant peripheral nerve sheath tumor (MPNST is biologically an aggressive tumor for which the treatment of choice is the surgery. We reviewed the clinical profile, diagnostic methods, treatment patterns, and outcome of twenty-four MPNST patients in this study. Patients and methods A retrospective analysis of 24 MPNST patients, treated from 1994 to 2002, in the department of Surgical Oncology at All India Institute of Medical Sciences, New Delhi, was done. A combination of gross, histopathological and immunohistochemical findings, and proliferation markers (MIB1 were considered for diagnosis and grade of the MPNST. Survival analysis was done by the Kaplan-Meier method and differences were evaluated with the log-rank test. Multivariate analysis was carried out by using Cox's proportional hazards model by using SPSS (Version 9, Chicago, Illinois software. Results MPNST constituted 12% of all soft tissue sarcomas, where 21% (5/24 of patients had associated Von Recklinghausen's disease (VRHD. A higher incidence of male preponderance and multifocal MPNST were noted in the present series. At a mean follow-up of 38 months, 13 (54 % patients had relapse of disease and 5-year over all and disease free survival were 58% and 35% respectively.

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

    2016-01-01

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

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

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

    Directory of Open Access Journals (Sweden)

    H.L. Chin

    2015-09-01

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

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

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

  20. Twenty-Four-Hour Urine Osmolality as a Physiological Index of Adequate Water Intake

    2015-01-01

    Full Text Available While associations exist between water, hydration, and disease risk, research quantifying the dose-response effect of water on health is limited. Thus, the water intake necessary to maintain optimal hydration from a physiological and health standpoint remains unclear. The aim of this analysis was to derive a 24 h urine osmolality (UOsm threshold that would provide an index of “optimal hydration,” sufficient to compensate water losses and also be biologically significant relative to the risk of disease. Ninety-five adults (31.5 ± 4.3 years, 23.2 ± 2.7 kg·m−2 collected 24 h urine, provided morning blood samples, and completed food and fluid intake diaries over 3 consecutive weekdays. A UOsm threshold was derived using 3 approaches, taking into account European dietary reference values for water; total fluid intake, and urine volumes associated with reduced risk for lithiasis and chronic kidney disease and plasma vasopressin concentration. The aggregate of these approaches suggest that a 24 h urine osmolality ≤500 mOsm·kg−1 may be a simple indicator of optimal hydration, representing a total daily fluid intake adequate to compensate for daily losses, ensure urinary output sufficient to reduce the risk of urolithiasis and renal function decline, and avoid elevated plasma vasopressin concentrations mediating the increased antidiuretic effort.

    The one-carbon unit transfer reaction of tetrahydrofolate coenzyme was initiated. Bisbenzimidazolium salts were used as a tetrahydrofolate coenzyme model, and thus the biomimetic synthesis of twenty-four acyclic dike-tones as precursors for macrocyclic ketones was successfully accomplished by using the addition-hydrolysis reac-tion of the bisbenzimidazolium salts with alkyl magnesium halide, wherein six diketones have not been reported in literature. Accordingly, a short route to muscone analogues was provided.

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

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

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

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

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

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

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

    Local blood flow in the forefoot (SBF) was measured continuously during 24 hours by 133xenon clearance technique in 10 patients prior to and at least 1 year after successful reconstructive vascular surgery for severe arterial insufficiency (mean: 18 months, range: 12-36). A group of 10 patients with normal peripheral circulation served as a control group. In spite of a considerable increase of the ankle/arm systolic blood pressure index--preoperative: 0.30 +/- 0.12, postoperative: 0.78 +/- 0.28 (mean +/- 1 SD)--the SBF decreased by 50% (p less than 0.001) following reconstructive vascular surgery during day activities. During sleep, however, SBF increased by 80% (p less than 0.001). The relative changes in SBF from day to night at the postoperative examination did not differ from that of the control group, i.e., the normal 24-hour blood flow pattern had been obtained. These changes in SBF are explained by the reappearance of peripheral vasoregulatory mechanisms. Postreconstructive hyperemia was evaluated by the same technique. The changes in SBF following surgery in the positions supine, awake and supine, asleep were found to be insignificant (0.80 less than p less than 0.90). It is concluded that the long-term postreconstructive hyperemia merely is a reflection of the normal 24-hour blood flow pattern.

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

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

    2010-11-01

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

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

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

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

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

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

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

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

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

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

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

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

    Charcot-Marie-Tooth disease is the single most common diagnosis associated with cavus foot. The imbalance involving intrinsic and extrinsic muscles has been suggested as the main pathogenetic cause of cavus foot in this disease. The goal of surgical treatment is to correct the deformity to obtain a plantigrade foot. In the presence of a flexible deformity and the absence of degenerative arthritis, preserving as much as possible of the overall range of motion of the foot and ankle is advisable. Twenty-four cavus feet in twelve patients with Charcot-Marie-Tooth disease were included in the study. Clinical evaluation was summarized with the Maryland Foot Score. Radiographic evaluation assessed calcaneal pitch, Meary angle, Hibb angle, and absence of degenerative joint changes. Only patients who had a flexible deformity, with varus of the heel reducible in the Coleman-Andreasi test, and did not have degenerative joint arthritis were included in this study. Surgical treatment consisted in plantar fasciotomy, midtarsal osteotomy, extensor hallucis longus tendon transfer to the first metatarsal (Jones procedure), and dorsiflexion osteotomy of the first metatarsal. Mean follow-up was six years (range, two to thirteen years). The mean Maryland Foot Score was 72 preoperatively and 86 postoperatively. The postoperative result was rated as excellent in twelve feet (50%), good in ten (42%), and fair in two (8%). Mean calcaneal pitch was 34° preoperatively and 24° at the time of the latest follow-up, the mean Hibb angle was 121° preoperatively and 136° postoperatively, and the mean Meary angle was 25° preoperatively and 2° postoperatively. Plantar fasciotomy, midtarsal osteotomy, the Jones procedure, and dorsiflexion osteotomy of the first metatarsal yielded adequate correction of flexible cavus feet in patients with Charcot-Marie-Tooth disease in the absence of fixed hindfoot deformity. The fact that the improvement in the outcome score was only modest may be attributable

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

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

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

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

  3. Diagnostics of septic arthritis in the sternoclavicular region - 10 consecutive patients and literature review

    2013-02-15

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

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

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

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

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

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

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

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

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

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

    Full Text Available Purpose. To review the postoperative seizure outcomes of patients that underwent surgery for epilepsy at King Faisal Specialist Hospital & Research Centre (KFSHRC. Methods. A descriptive retrospective study for 502 patients operated on for medically intractable epilepsy between 1998 and 2012. The surgical outcome was measured using the ILAE criteria. Results. The epilepsy surgery outcome for temporal lobe epilepsy surgery (ILAE classes 1, 2, and 3 at 12, 36, and 60 months is 79.6%, 74.2%, and 67%, respectively. The favorable 12- and 36-month outcomes for frontal lobe epilepsy surgery are 62% and 52%, respectively. For both parietal and occipital epilepsy lobe surgeries the 12- and 36-month outcomes are 67%. For multilobar epilepsy surgery, the 12- and 36-month outcomes are 65% and 50%, respectively. The 12- and 36-month outcomes for functional hemispherectomy epilepsy surgery are 64.2% and 63%, respectively. According to histopathology diagnosis, mesiotemporal sclerosis (MTS and benign CNS tumors had the best favorable outcome after surgery at 1 year (77.27% and 84.3%, resp., and 3 years (76% and 75%, resp.,. The least favorable seizure-free outcome after 3 years occurred in cases with dual pathology (66.6%. Thirty-four epilepsy patients with normal magnetic resonance imaging (MRI brain scans were surgically treated. The first- and third-year epilepsy surgery outcome of 17 temporal lobe surgeries were (53% and (47% seizure-free, respectively. The first- and third-year epilepsy surgery outcomes of 15 extratemporal epilepsy surgeries were (47% and (33% seizure-free. Conclusion. The best outcomes are achieved with temporal epilepsy surgery, mesial temporal sclerosis, and benign CNS tumor. The worst outcomes are from multilobar surgery, dual pathology, and normal MRI.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

    Patients with drug-induced type 1 Brugada electrocardiograms (BrECGs) are considered to have good prognosis. Spontaneous type 1 is, instead, considered a risk factor; however, it is probably underestimated because of the BrECG fluctuations. The aim of this study was to analyze, in a large population of patients with Br, the real prevalence of type 1 BrECG using 12-lead 24-hour Holter monitoring (12L-Holter) and its correlation with the time of the day. We recorded 303 12L-Holter in 251 patients. Seventy-five (30%) patients exhibited spontaneous type 1 BrECG at 12-lead ECG (group 1) and 176 (70%) had only drug-induced type 1 (group 2). Type 1 BrECG was defined as "persistent" (>85% of the recording), "intermittent" (Holter, 57% intermittent type 1%, and 31% never had type 1; in group 2, none had persistent type 1, 20% had intermittent type 1%, and 80% never showed type 1. To evaluate the circadian fluctuations of BrECG, 4 periods in the day were considered. Type 1 BrECG was more frequent between 12-noon and 6 p.m. (52%, p Holter than with conventional follow-up with periodic ECGs and this has important implications in the risk stratification. 12L-Holter recording might avoid 20% of the pharmacological challenges with sodium channel blockers, which are not without risks, and should thus be considered as the first screening test, particularly in children or in presence of borderline diagnostic basal ECG.

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

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

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

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

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

    The perceived benefits of bandaging for 10 days following pinnaplasty have been questioned by previous studies. The problems arising from these dressings are many [Powell BWEM.

Complications following correction of prominent ears: an audit review of 122 cases. Br J Plast Surg 1999;52:588-90]. Eighty children were recruited into a prospective randomised controlled trial comparing the use of a head bandage for only 24 h with a standard practise of a 10-day head bandage. A preoperative measurement of the lateral ear projection (LEP) was made. The outcome measures recorded during the two planned postoperative visits at 10 days (visit 1) and 2 months (visit 2) were: patient satisfaction score, LEP, complications and any unscheduled hospital visits associated with the surgery. There was no significant difference in LEP and patient satisfaction between the two groups at both the scheduled postoperative visits. Differences between the groups in the number of unscheduled visits (p=0.21) did not reach statistical significance. The findings indicate that it is safe and effective to use head bandage for only 24 h following surgical correction of prominent ears. This study shows no benefit from the application of a formal head bandage for any longer than 1 day.

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

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

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

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

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

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

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

    2016-12-01

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

  15. What are the intensities and line-shapes of the twenty four polarization terms in coherent anti-Stokes Raman spectroscopy?

    Directory of Open Access Journals (Sweden)

    Kai Niu

    2015-12-01

    Full Text Available Coherent anti-Stokes Raman spectroscopy (CARS is conventionally described by just one diagram/term where the three electric field interactions act on the ket side in a Feynman dual time-line diagram in a specific time order of pump, Stokes and probe pulses. In theory, however, any third-order nonlinear spectroscopy with three different electric fields interacting with a molecule can be described by forty eight diagrams/terms. They reduce to just 24 diagrams/terms if we treat the time ordering of the electric field interactions on the ket independently of those on the bra, i.e. the ket and bra wave packets evolve independently. The twenty four polarization terms can be calculated in the multidimensional, separable harmonic oscillator model to obtain the intensities and line-shapes. It is shown that in fs/ps CARS, for the two cases of off-resonance CARS in toluene and resonance CARS in rhodamine 6G, where we use a fs pump pulse, a fs Stokes pulse and a ps probe pulse, we obtain sharp vibrational lines in four of the polarization terms where the pump and Stokes pulses can create a vibrational coherence on the ground electronic state, while the spectral line-shapes of the other twenty terms are broad and featureless. The conventional CARS term with sharp vibrational lines is the dominant term, with intensity at least one order of magnitude larger than the other terms.

It is shown that in fs/ps CARS, for the two cases of off-resonance CARS in toluene and resonance CARS in rhodamine 6G, where we use a fs pump pulse, a fs Stokes pulse and a ps probe pulse, we obtain sharp vibrational lines in four of the polarization terms where the pump and Stokes pulses can create a vibrational coherence on the ground electronic state, while the spectral line-shapes of the other twenty terms are broad and featureless. The conventional CARS term with sharp vibrational lines is the dominant term, with intensity at least one order of magnitude larger than the other terms.

    Full Text Available Abstract Background In Papua New Guinea (PNG, combination therapy with amodiaquine (AQ or chloroquine (CQ plus sulphadoxine-pyrimethamine (SP was introduced as first-line treatment against uncomplicated malaria in 2000. Methods We assessed in vivo treatment failure rates with AQ+SP in two different areas in PNG and twenty-four molecular drug resistance markers of Plasmodium falciparum were characterized in pre-treatment samples. The aim of the study was to investigate the association between infecting genotype and treatment response in order to identify useful predictors of treatment failure with AQ+SP. Results In 2004, Day-28 treatment failure rates for AQ+SP were 29% in the Karimui and 19% in the South Wosera area, respectively. The strongest independent predictors for treatment failure with AQ+SP were pfmdr1 N86Y (OR = 7.87, p pfdhps A437G (OR = 3.44, p pfcrt K76T, A220S, N326D, and I356L did not help to increase the predictive value, the most likely reason being that these mutations reached almost fixed levels. Though mutations in SP related markers pfdhfr S108N and C59R were not associated with treatment failure, they increased the predictive value of pfdhps A437G. The difference in treatment failure rate in the two sites was reflected in the corresponding genetic profile of the parasite populations, with significant differences seen in the allele frequencies of mutant pfmdr1 N86Y, pfmdr1 Y184F, pfcrt A220S, and pfdhps A437G. Conclusion The study provides evidence for high levels of resistance to the combination regimen of AQ+SP in PNG and indicates which of the many molecular markers analysed are useful for the monitoring of parasite resistance to combinations with AQ+SP.

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

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

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

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

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

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

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

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

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

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

    2014-01-01

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

    The usefulness of combined anti-HCV and 24 mini-pool HCV RNA screening strategy was re-evaluated after a six-year continuous routine use in a clinical virology laboratory, at which more than half of newly diagnosed hepatitis C patients are intravenous drug users. Pools of 24 samples were prepared from 20,448 anti-HCV negative serum samples and tested using an automated commercial PCR assay with a lower limit of detection of 50 IU/ml. After detection of anti-HCV negative/HCV RNA positive patients, responsible physicians provided follow-up samples. Thirty-eight (0.19%) anti-HCV negative/HCV RNA positive samples from 30 patients (28 intravenous drug users) were detected. Follow-up samples were available for 27/30 patients. Twenty, six and one patient seroconverted in the second, third and fourth available samples, respectively. The interval between the first HCV RNA positive and the first available anti-HCV positive sample was 17-517 days. The costs of detecting a single anti-HCV negative/HCV RNA positive patient were 1227 Euros. Combined anti-HCV and 24 mini-pool HCV RNA screening is a useful and cost effective strategy, not only in blood-transfusion settings but also in a routine clinical virology laboratory, at which a significant proportion of the tested population belongs to a high-risk population.

    Modifications of heart rate (HR) and systolic blood pressure (SBP) variabilities (V) have been reported in the human syndrome arterial hypertension plus insulin-resistance. The aim of this study was to characterize the 24 h SBPV and HRV in both time and frequency domains during weight increase in dogs fed ad libitum with a high fat diet. Implantable transmitter units for measurement of blood pressure and heart rate were surgically implanted in five beagle male dogs. BP and HR were continuously recorded using telemetric measurements during 24 hours, before and after 6 and 9 weeks of hypercaloric diet in quiet animals submitted to a 12h light-dark cycle. To study nychtemeral cycle of SBP and HR, two periods were chosen: day (from 6.00 h to 19.00 h) and night (from 23.00 h to 6.00 h). Spontaneous baroreflex efficiency was measured using the sequence method. Spectral variability of HR and SBP was analyzed using a fast Fourier transformation on 512 consecutive values and normalized units of low (LF: 50-150 mHz, reflecting sympathetic activity) and high (HF: respiratory rate +/- 50 mHz, reflecting parasympathetic activity) frequency bands were calculated. The energy of total spectrum (from 0.004 to 1 Hz) was also studied. Body weight (12.4 +/- 0.9 vs 14.9 +/- 0.9 kg, p < 0.05). SBP (132 +/- 1 vs 147 +/- 1 mmHg, p < 0.05) significantly increased after 9 weeks of hypercaloric diet. A nycthemeral HR rhythm was present at baseline (day: 79 +/- 1 vs night: 71 +/- 1 bpm) but not after 9 weeks (day: 91 +/- 4 bpm ; night: 86 +/- 2 bpm). Concomitantly, the efficiency of spontaneous baroreflex decreased at 6 weeks (36 +/- 1 vs 42 +/- 2 mmHg/ms, p < 0.05). A significant decrease in HF energy of HRV was found after 6 but not after 9 weeks. LF energy of SBPV was increased at 6 but not at 9 weeks (table). [table: see text] In conclusion, this study shows that an hyperlipidic and hypercaloric diet induces transient variations in autonomic nervous system activity which could be the

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

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

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

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

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

    The DENERHTN trial (Renal Denervation for Hypertension) confirmed the blood pressure (BP) lowering efficacy of renal denervation added to a standardized stepped-care antihypertensive treatment for resistant hypertension at 6 months. We report here the effect of denervation on 24-hour BP and its variability and look for parameters that predicted the BP response. Patients with resistant hypertension were randomly assigned to denervation plus stepped-care treatment or treatment alone (control). Average and standard deviation of 24-hour, daytime, and nighttime BP and the smoothness index were calculated on recordings performed at randomization and 6 months. Responders were defined as a 6-month 24-hour systolic BP reduction ≥20 mm Hg. Analyses were performed on the per-protocol population. The significantly greater BP reduction in the denervation group was associated with a higher smoothness index (P=0.02). Variability of 24-hour, daytime, and nighttime BP did not change significantly from baseline to 6 months in both groups. The number of responders was greater in the denervation (20/44, 44.5%) than in the control group (11/53, 20.8%; P=0.01). In the discriminant analysis, baseline average nighttime systolic BP and standard deviation were significant predictors of the systolic BP response in the denervation group only, allowing adequate responder classification of 70% of the patients. Our results show that denervation lowers ambulatory BP homogeneously over 24 hours in patients with resistant hypertension and suggest that nighttime systolic BP and variability are predictors of the BP response to denervation.

    Central blood pressure (BP) is increasingly considered as a better estimator of hypertension associated risks. We aimed to evaluate the association of 24-h central BP, in comparison with 24-h peripheral BP, with the presence of target organ damage (TOD). Cross-sectional study of 208 hypertensive patients, aged 57 ± 12 years, 34% women. Office (mean of 4 measurements) and 24-h central and peripheral BP were measured by the oscillometric Mobil-O-Graph device. TOD was assessed at cardiac (left ventricular hypertrophy by echocardiography), renal (reduction of glomerular filtration rate and/or microalbuminuria), and arterial (increased aortic pulse wave velocity) levels. A total of 107 patients (51.4%) had TOD (77, 35% patients left ventricular hypertrophy; 54, 25.9% renal abnormalities; and 40, 19.2% arterial stiffness). All SBP and pulse BP estimates (office, 24-h, daytime, and night-time) were associated with the presence of TOD, after adjustment for age, sex, and antihypertensive treatment, with higher odds ratios for ambulatory-derived values. Odds ratios for central and peripheral BP were similar for all office, 24-h, daytime, and night-time BP. After simultaneous adjustment, peripheral, but not central, 24-h and night-time SBP and pulse pressures were associated with the presence of TOD. TOD in hypertension is associated with BP elevation, independently of the type of measurement (office or ambulatory, central or peripheral). Central BP, even monitored during 24 h, is not better associated with TOD than peripheral BP. These results do not support a routine measurement of 24-h central BP.

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

    Full Text Available Cerebral edema is a common disease, secondary to craniocerebral injury, and real-time continuous monitoring of cerebral edema is crucial for treating patients after traumatic brain injury. This work established a noninvasive and noncontact system by monitoring the magnetic induction phase shift (MIPS which is associated with brain tissue conductivity. Sixteen rabbits (experimental group n = 10, control group, n = 6 were used to perform a 24 h MIPS and intracranial pressure (ICP simultaneously monitored experimental study. For the experimental group, after the establishment of epidural freeze-induced cerebral edema models, the MIPS presented a downward trend within 24 h, with a change magnitude of −13.1121 ± 2.3953°; the ICP presented an upward trend within 24 h, with a change magnitude of 12–41 mmHg. The ICP was negatively correlated with the MIPS. In the control group, the MIPS change amplitude was −0.87795 ± 1.5146 without obvious changes; the ICP fluctuated only slightly at the initial value of 12 mmHg. MIPS had a more sensitive performance than ICP in the early stage of cerebral edema. These results showed that this system is basically capable of monitoring gradual increases in the cerebral edema solution volume. To some extent, the MIPS has the potential to reflect the ICP changes.

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

    To evaluate the contribution of CT for the management of patients with severe acute exacerbation of colitis (SAC) complicating inflammatory bowel disease (IBD); in particular, its contribution to surgical decision making. All patients who were admitted to our institution for SAC complicating IBD were divided into two groups: group A (those who received surgical treatment); and group B (those who received medical treatment). Admission CT results were compared between groups. From 2006 to 2015, 54 patients [26 male; median age 39 (17-71) years] presenting with SAC were placed in either group A (n = 41; 76%) or group B (n = 13; 24%). Surgical patients in group A more frequently had altered general status (50 vs 17%; P = 0.01). Physical examination, Lichtiger score, endoscopic findings and laboratory results were similar between the groups. There was no significant difference in CT data between the groups with respect to extent of the colitis (pan-colitis in 54 and 69%, respectively, P = 0.35), median colonic thickness [10 (4-16) vs 8 (6-11) mm, P = 0.15], target enhancement (88 vs 77%, P = 0.38) and occurrence of toxic megacolon (2 vs 0%).

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

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

    A lot of researches have been done about the aesthetics of the Twenty-four Poetry Style for several years. The highly theoretical aesthetic researches which include framing aesthetics, thought aesthetics, ecological esthetics, poetic aesthetics and ideal aesthetics make this book more attractive. But on the other hand, some expansion exists in the aesthetic value of this book because the researchers add their aesthetic theories to the theoretic distillation of the book. In this article, the directly perceived dim beauty and the burden of dim beauty have been analyzed from the experience of the aesthetic perception, which will clearly display the beauty of the Twenty-four Poetry Style.%历年来关于《二十四诗品》的美学研究是层出不穷的,从架构美学到思想美学到生态美学到诗歌美学到理想美学等等,这种高度理论性的美学研究使得整部著作更加具有魅力性。但是这种提炼浓缩后的理论升华在无形中也附加上了论者们的美学理想,使得《二十四诗品》美学价值或多或少地存在着“膨胀”的现象。文章将从美感体验出发,旨在挖掘分析能被直接感知的朦胧美和美的朦胧负担,让《二十四诗品》的美变得更加有迹可循。

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

    Robotic surgery is a new technology which may expand the variety of operations a surgeon can perform with minimally invasive techniques. We present a retrospective review of our first 100 consecutive robotic cases in children. A three-arm robot was used with one camera arm and two instrument arms. Additional accessory ports were utilized as necessary. Two different attending surgeons performed the procedures. Twenty-four different types of procedures were completed using the robot. The majority of the procedures (89%) were abdominal procedures with 11% thoracic. No urology or cardiac procedures were performed. Age ranged from 1 day to 23 years with an average age of 8.4 years. Weight ranged from 2.2 to 103 kg with a median weight of 27.9 kg. Twenty-two patients were less than 10.0 kg. Examples of cases included gastrointestinal (GI) surgery, hepatobiliary, surgical oncology, and congenital anomalies. The overall majority of cases had never been performed minimally invasively by the authors. The overall intraoperative conversion rate to open surgery was 13%. One case (1%) was converted to thoracoscopic because of lack of domain for the articulating instruments. No conversions or complications occurred as a result of injuries from the robotic instruments. Interestingly, four abdominal cases were converted to open surgery due to equipment failures or injuries from standard laparoscopic instruments used through non-robotic accessory ports. Robotic surgery is safe and effective in children. An enormous variety of cases can be safely performed including complex cases in neonates and small children. Simple operations such as cholecystectomies have minimal advantages by using robotic technology but can serve as excellent teaching tools for residents and newcomers to this form of minimally invasive surgery (MIS). The technology is ideal for complex hepatobiliary cases and thoracic surgery, particularly solid chest masses.

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

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

    Mucocele of the appendix is an uncommon condition where luminal distention by mucin is usually attributable to a mucinous cystadenoma. From a surgical standpoint, it is critical that the mucin-filled tumor remains intact during resection. Spillage of mucin into peritoneal cavity may otherwise lead to pseudomyxoma peritonei. Although acute appendicitis is managed successfully by laparoscopic appendectomy, the potential for rupture has fueled concerns over laparoscopic resection of appendiceal mucoceles. Our aim was to evaluate feasibility, safety, and short-term outcomes of laparoscopic resection in patients with a mucocele of appendix secondary to mucinous cystadenoma. Data collected prospectively at the Department of Surgery from October 2005 to December 2013 were reviewed, selecting all instances of preoperatively identified appendiceal mucoceles, which was confirmed as mucinous cystadenomas by histology after elective laparoscopic surgery. Patient demographics, surgical data (operative procedures and times, intraoperative complications), and short-term postoperative outcomes were analyzed retrospectively. Twenty-four consecutive patients (female 14) were studied. Mean age was 60.0 years (range 42-81 years). Surgical procedures included simple appendectomy (1/24, 4.2 %), partial cecectomy (15/24, 62.5 %), and ileocecal resection (8/24, 33.3 %). Mean operative time was 108.5 min (range 40-205 min). No intraoperative spillage of mucin occurred due to inadvertent rupture of tumor. Resection margins uniformly were negative for tumor. Mean maximal length and diameter of tumors were 7.9 cm (range 3.0-20.0 cm) and 3.2 cm (range 1.0-7.5 cm), respectively. One patient (4.2 %) suffered postoperative morbidity (wound infection). A laparoscopic approach proved feasible and safe for surgical management of appendiceal mucocele due to mucinous cystadenoma. However, long-term follow-up is warranted for more conclusive support.

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

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

    Full Text Available ABSTRACT: Introduction & Objective: It is well established that adrenal hormone cortisol has long been used in human psychobiological studies as a biological marker of circadian rhythm, stress, and anxiety. There is little information, however, about the interrelationships of night work, plasma cortisol levels in females’ nurses of the developing countries. The aim of the present study was to compare circadian cortisol profile between two groups of nurses with shift and permanent work in a Hospital affiliated to Shiraz University of Medical Sciences, Iran, between January 2006 to September 2008. Materials & Methods: In this experimental study, we examined the reproducibility of plasma cortisol levels during one month period in 34 shift work nurses and 10 permanent day shift works. We evaluated potential associations between night work and hormone levels, using current and shift work information for the health care shift workers. Results: The results clearly revealed that shift work significantly increased nighttime cortisol levels (34.93 μg/dl during night shift and decreased the peak levels of cortisol in the morning (39.03 μg/dl. During the work shift the plasma cortisol presented a decreased concentration in the morning and increasing levels (44.93 μg/dl by the end of the evening. In contrast , the permanent day work nurses, who had never worked at night shifts, showed a lowest secretion of cortisol during the first half of night time sleep (10.02 μg/dl , and a peak value of the cortisol after awakening at 07:00 h ( 59.75 μg/ml. We also observed a significant association between night work and increased levels of cortisol over the remaining of the day. Conclusion: It can be concluded that nurses with night shift work have an abnormal cortisol secretion profile. Shift work nurses on rotating night shifts seem to experience changes in hormones levels that may be associated with increased of circadian disorders risk observed among night – shift workers.

    Intravenous iloprost is an important option in the treatment of ischemic disease of the lower limbs; however, the administration of therapy is frequently compromised because of the need for long cycles of infusion in a hospital setting. The aim of the study is to evaluate the efficacy, safety, feasibility, and the economic impact of infusion therapy in the outpatient setting. Twenty-four consecutive patients were treated with iloprost at their homes where they were administered a slow rate of infusion for 24 hours a day, during 9.9 ± 2.3 days, with a portable syringe pump (Infonde®). The clinical condition of patients evaluated with the modified SVS/ISCVS scale significantly improved after treatment (+1.29 ± 1.04 points vs. baseline, piloprost in the outpatient setting is effective, safe, feasible, and more acceptable to patients than infusion at the hospital. In addition, it has a favorable economic and organizational impact on the medical ward.

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

    Retrospective review. To evaluate key risk factors for the development of C5 palsy after cervical corpectomy, including resection of the posterior longitudinal ligament (PLL). Postoperative C5 palsy is a well-known complication after cervical spine surgery. It is unknown whether resection of the PLL affects the incidence of C5 palsy. We performed a retrospective review of 459 consecutive patients undergoing anterior cervical corpectomies over a 15-year period. Medical records were reviewed to gather demographic data, operative details, and the incidence of C5 palsy. We performed regression analyses to identify variables that predicted the development of C5 palsy. Our final analysis included 397 patients (females 51.4%, mean age 55.6 ± 11.6 yrs). Anterior corpectomy alone was performed in 255 (64.2%) patients, and combined anterior and posterior fusion was performed in 142 (35.8%) patients. Twenty-four patients (6.0%) developed C5 nerve palsy. Univariable regression demonstrated age greater than 65 (odds ratio, OR 2.7, 95% confidence interval, CI 1.2 to 6.3), corpectomy of three or more levels (OR 6.3, 95% CI 2.1 to 18.9), presence of ossification of the PLL (OR 4.3, 95% CI 1.6 to 11.7), and complete or partial resection of the PLL (OR 2.6, 95% CI 1.0 to 6.7) predicted development of C5 palsy. Multivariable regression demonstrated that the odds of getting C5 palsy with complete or partial resection of the PLL is 4.0 times (95% CI 1.5 to 10.5) higher compared with patients with an intact PLL. There were no significant differences in C5 palsy rates based on surgical approach (anterior vs. anterior plus posterior), sex, smoking status, or diabetes. Age greater than 65 years, corpectomy of three or more levels, presence of ossification of the PLL, and complete or partial resection of the PLL significantly predicted the development of C5 palsy. 4.

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

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

    The purpose of the study was to evaluate the 10- to 18-year follow-up of cementless acetabular fixation in patients 50 years and younger. We retrospectively reviewed a consecutive group of 118 patients (144 hips) in whom primary total hip arthroplasty had been performed by 2 surgeons using a cementless acetabular component. Two (1.4%) cementless acetabular components were revised because of aseptic loosening. Twenty-four hips (16.7%) were revised for any mechanical failure of the acetabular component mostly related to acetabular liner wear and osteolysis. The average linear wear rate was 0.19 mm per year, which was higher than our previous reports with cemented acetabular fixation. The fiber mesh ingrowth surface of the cementless acetabular component in this study was superior to cemented acetabular components in terms of fixation. However, the high rates of wear and osteolysis have led to poor overall acetabular component construct survivorship.

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

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

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

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

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

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

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

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

    Full Text Available Given the higher mortality rate of ICU patients with sepsis and AKI, we decided to investigate the possible correlation between serum biomarkers of organ damage, and endotoxin activity in ICU septic patients. Ninety-eight consecutive adult patients were enrolled in this study. Patients were divided in two groups depending on the presence of sepsis. Fifty-six patients had sepsis, while forty-two patients were nonseptic. Among septic patients, twenty-four subjects developed AKI, while thirty-two did not. AKI occurred in fourteen patients without sepsis as well. The levels of NGAL, BNP, and AOPP were significantly higher among septic patients compared with nonseptic subjects (P<0.001. Among septic patients, subjects who developed AKI showed significant higher levels of NGAL and AOPP (P=0.0425 and BNP (P=0.0327. Among patients who developed AKI, a significant difference was found only in terms of AOPP levels between septic and nonseptic patients. The correlation between endotoxin activity and BNP in septic patients and the increase in the levels of NGAL, BNP, and AOPP in case of sepsis and AKI, in particular if they are associated, indicate a multiorgan involvement in these two conditions.

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

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

    To evaluate the larynx involvement in patients with rheumatoid arthritis (RA) in a clinical setting and correlate with the different clinical features related to more aggressive disease. Cross-sectional study including 36 consecutive patients with RA. Reflux symptoms were evaluated by the Reflux Symptom Index (RSI) and vocal cord impairment by the Voice Handicap Index-10 (VHI-10). Laryngeal involvement was done by videolaryngostroboscopy (VLS). The mean age was 56,3 ± 14 years with a mean disease duration of 2,6 ± 3,1 years (range 0-16 years). Voice use was considered as professional users in 33%. Twenty-four (67%) out of 36 patients had abnormal findings of VLS. One patient had larynx nodules (bamboo nodules). Eleven patients (31%) were diagnosed with muscle tension dysphonia, and there were symptoms and signs of pharyngeal-laryngeal reflux in 23 (64%) patients. No signs of cricoarytenoid joint impairment was found. Organic larynx involvement was uncommon in patients with RA. However symptoms and signs of pharyngeal-laryngeal reflux were seen in around 60% of patients. There was no correlation between the clinical phenotype, severity of disease, immunological profile or treatment with VLS findings. Copyright © 2013 Elsevier España, S.L. All rights reserved.

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

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

    Patients with metastatic solid tumors (MST) with less than a complete response to chemotherapy (L-CR), a depressed immune system and elevated serum vascular endothelial growth factor (VEGF) lack defined treatment options. The primary endpoint evaluated in this study was whether interleukin-2 (IL-2) and 13-cisretinoic acid (RA) treatment reduced VEGF and improved immune function in such patients. Secondary endpoints were objective response, relapse-free survival (RFS), and overall survival (OS). One hundred consecutive MST patients with L-CR and a mean serum VEGF of 421.0 pg/mm3 were enrolled. Patients self-administered subcutaneous IL-2 1.8 x 10(6) IU/day, and oral RA 0.5 mg/kg/day x 5 days/week for 2 cycles of 3 weeks/month for 1 year and continued until progression. After a median follow-up of 78 months, a statistically significant VEGF decrease and improvements in lymphocyte, NK, and CD4+/CD8+ ratio were observed. Twenty-four patients were converted to a CR; their 5-year RFS and OS rates were each 96%. No WHO grade 3 or 4 toxicities were observed. Administration of IL-2/RA to this patient population produced a significant decrease in VEGF, improvement of prognostically relevant immunological parameters, and durable response in 25% of patients.

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

    Indocyanine green (ICG) videoangiography (VA) in cerebral aneurysm surgery allows confirmation of blood flow in parent, branching, and perforating vessels as well as assessment of remnant aneurysm parts after clip application. A retrospective analysis and review of the literature were conducted to determine the current essential advantages of ICG-VA in aneurysm surgery. The authors retrospectively evaluated all aneurysm cases treated with the aid of intraoperative ICG-VA at a single institution between 2007 and 2013. They also analyzed the literature published since the initial description of ICG-VA in 2003. Two hundred forty-six procedures were performed in 232 patients harboring 295 aneurysms. The patients, whose mean age was 54 years, consisted of 159 women and 73 men. One hundred twenty-four surgeries were performed after subarachnoid hemorrhage, and 122 were performed for incidental aneurysms. Single aneurysms were clipped in 185 patients, and multiple aneurysms were clipped in 47 (mean aneurysm diameter 6.9 mm, range 2-40 mm). No complications associated with ICG-VA occurred. Intraoperative microvascular Doppler ultrasonography was performed before ICG-VA in all patients, and postoperative digital subtraction angiography (DSA) studies were available in 121 patients (52.2%) for retrospective comparative analysis. In 22 (9%) of 246 procedures, the clip position was modified intraoperatively as a consequence of ICG-VA. Stenosis of the parent vessels (16 procedures) or occlusion of the perforators (6 procedures), not detected by micro-Doppler ultrasonography, were the most common problems demonstrated on ICG-VA. In another 11 procedures (4.5%), residual perfusion of the aneurysm was observed and one or more additional clips were applied. Vessel stenosis or a compromised perforating artery occurred independent of aneurysm location and was about equally common in middle cerebral artery and anterior communicating artery aneurysms. In 2 procedures (0.8%), aneurysm

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

    The assessment of the cardiovascular risk profile in patients with end-stage liver disease is essential prior to liver transplantation (LT) as cardiovascular diseases are major causes of morbidity and mortality in the posttransplant course. The aim of this study was to evaluate the accuracy of a 64-slice coronary computed tomographic angiography (CTA) and coronary calcium scoring (CCS) to predict the postoperative cardiovascular risk of patients assessed for LT. In this single center, observational study we included 54 consecutive patients who were assessed for LT and consequently transplanted. Twenty-four patients (44%) presented with a high CCS above 300 and/or a significant stenosis (>50% percent narrowing due to stenotic plaques) and were further referred to coronary angiography. Three of these patients had a more than 70% LAD stenosis with subsequent angioplasty (n = 1) or conservative therapy (n = 2). The other patients showed only diffuse CAD without significant stenosis. The remaining 30 patients with normal CTA findings were listed for LT without further tests. None of the 54 patients developed cardiovascular events peri- and postoperatively. This study indicated that CTA combined with CCS is a useful non-invasive imaging technique for pre-LT assessment of coronary artery disease and safe tool in the risk assessment of peri- and postoperative cardiovascular events in patients undergoing LT.

    Based on daily air temperature from 1951-2010, mean air temperature (MAT) and the beginning-day air temperature (BAT), variation characteristics of the twenty-four solar terms in Xi'an were examined. MAT and BAT of phenological solar terms (Waking of Insects, Pure Brightness, Lesser Fullness of Grain and Grain in Beard) were used. We found that MAT of Lesser Heat and Greater Heat was higher than other solar terms, Lesser Cold was the coldest in all. Ending-day air temperature (EAT) was higher than BAT in each solar term from Greater Cold to Lesser Heat, and was lower than BAT in each solar term from Greater Heat to Lesser Cold. Curve of MAT variation of contiguous solar terms showed a single peak at Pure Brightness which was 3.4℃ higher than the Spring Equinox and single valley at the Beginning of Winter which was 3.9℃ lower than Frost's Descent. Daily MAT of seasonal solar terms varied as follows: spring (+0.190℃/ d) > autumn (-0.180℃/d) > winter (-0.105℃/d) > summer (+0.086℃/d). Daily MAT during the Beginning of Winter(-0.303℃/d), Waking of Insects (+0.233℃/d), Lesser Snow(-0.220℃/d) and Spring Equinox(+0.219℃/d) varied violently. MAT and BAT of most twenty-four solar terms showed a significant rising trend in the 1990s or 2000s, but BAT of autumn and winter solar terms did not change significantly in decadal temperature from 1951 to 2010. In 2000s, MAT of the Beginning of Spring, Greater Heat, the Beginning of Autumn, the End of Heat and the Winter Solstice dropped instead of rise. BAT and MAT of Waking of Insects rose in 1998 and 2008 at the 0.05 significant level, then in 2001 and 2010 at the 0.01 significant level. Pure Brightness and Lesser Fullness of Grain suddenly wanned in the 1990s (1999 and 1993), with 0.05 significant level at the beginning of 2000s (2004 and 2003) and 0.01 significant level in the mid-2000s (2006 and 2006). MAT and BAT of Grain in Beard showed a periodic rising and dropping trend, when it suddenly dropped at the

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

    During doctor-patient interactions, many messages are transmitted without words, through non-verbal communication. To elucidate the types of non-verbal behaviours perceived by patients interacting with family GPs and to determine which cues are perceived most frequently. In-depth interviews with patients of family GPs. Nine family practices in different regions of Poland. At each practice site, interviews were performed with four patients who were scheduled consecutively to see their family doctor. Twenty-four of 36 studied patients spontaneously perceived non-verbal behaviours of the family GP during patient-doctor encounters. They reported a total of 48 non-verbal cues. The most frequent features were tone of voice, eye contact, and facial expressions. Less frequent were examination room characteristics, touch, interpersonal distance, GP clothing, gestures, and posture. Non-verbal communication is an important factor by which patients spontaneously describe and evaluate their interactions with a GP. Family GPs should be trained to better understand and monitor their own non-verbal behaviours towards patients.

    Rhenium-186 hydroxyethylidene diphosphonate ([sup 186]Re-HEDP) has been used for the palliative treatment of metastatic bone pain. A phase 1 dose escalation study was performed using [sup 186]Re-HEDP. Twenty-four patients with hormone-resistant prostate cancer entered the study. Each patient had at least four bone metastases and adequate haematological function. Groups of at least three consecutive patients were treated with doses starting at 1295 MBq and increasing to 3515 MBq (escalated in increments of 555 MBq). Thrombocytopenia proved to be the dose-limiting toxicity, while leucopenia played a minor role. Early death occurred in one patient (10 days after administration) without clear relationship to the [sup 186]Re-HEDP therapy. Transient neurological dysfunction was seen in two cases. Two patients who received 3515 MBq [sup 186]Re-HEDP showed grade 3 toxicity (thrombocytes 25-50 x 10[sup 9]/l), defined as unacceptable toxicity. After treatment alkaline phosphatase levels showed a transient decrease in all patients (mean: 26% [+-] 10% IU/l; range: 11%-44%). Prostate-specific antigen values showed a decline in eight patients, preceded by a temporary increase in three patients. From this study we conclude that the maximally tolerated dose of [sup 186]Re-HEDP is 2960 MBq. A placebo-controlled comparative study on the efficacy of [sup 186]Re-HEDP has been initiated. (orig.)

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

    To investigate the efficacy and safety of inhaled iloprost on top of other pulmonary hypertension (PH) specific therapies for patients with PH and severe right heart failure. We consecutively enrolled WHO functional class IV patients with PH and chronic thromboembolic pulmonary hypertension (CTEPH) in Shanghai Pulmonary Hospital from January 2011 to January 2013. Inhaled iloprost was administrated to all enrolled patients, oral endothelin antagonist receptors (ERAs) and/or type 5 phosphodiasterase inhibitors (PDE5-I) were also used as basis therapies. The in-hospital outcomes and the changes of right heart functional parameters were observed. Twenty-four patients with PH and 5 patients with CTEPH were enrolled. After a mean treatment duration of (23 ± 13) days, 3 patients dead and significant improvement was observed in the remaining 26 patients. Compared with the baseline, heart rate decreased from (99 ± 14) to (91 ± 12) bpm (P = 0.001), plasma NT-proBNP level decreased from 5 823 (3 029-13 248) to 3 220 (1 678-6 720) ng/L (P iloprost on top of other PAH-specific target therapy medications is effective and safe for PH patients with severe right heart failure.

    Full Text Available Background. The incidence of spine metastasis is expected to increase as the population ages, and so is the number of palliative spinal procedures. Minimally invasive procedures are attractive options in that they offer the theoretical advantage of less morbidity. Purpose. The purpose of our study was to evaluate whether minimally invasive posterior spinal instrumentation provided significant pain relief and improved function. Study Design. We compared pre- and postoperative pain scores as well as ambulatory status in a population of patients suffering from oncologic conditions in the spine. Patient Sample. A consecutive series of patients with spine tumors treated minimally invasively with stabilization were reviewed. Outcome Measures. Visual analog pain scale as well as pre- and postoperative ambulatory status were used as outcome measures. Methods. Twenty-four patients who underwent minimally invasive posterior spinal instrumentation for metastasis were retrospectively reviewed. Results. Seven (29% patients were unable to ambulate secondary to pain and instability prior to surgery. All patients were ambulating within 2 to 3 days after having surgery (=0.01. The mean visual analog scale value for the preoperative patients was 2.8, and the mean postoperative value was 1.0 (=0.001. Conclusion. Minimally invasive posterior spinal instrumentation significantly improved pain and ambulatory status in this series.

    The results of previous randomised controlled trials suggest that radiation oncologists should consider the presence of neuropathic pain when they prescribe dose fractionations for painful bone metastases. Although validated screening tools for neuropathic pain features are currently available, the prevalence of such features among patients with painful bone metastases is still poorly understood. The purpose of this study was to estimate the prevalence of neuropathic pain features among patients who received palliative radiotherapy for painful bone metastases. We conducted a cohort survey of consecutive patients who received palliative radiotherapy for painful bone metastases at St Luke's International Hospital between 2013 and 2014. Patients were prospectively assessed before radiotherapy using the validated screening questionnaire to identify neuropathic pain components in Japanese patients. Pain with neuropathic features was prospectively defined using the total score of the seven-item questionnaire and a cut-off score ≥9. The pain response was assessed 2 months after the start of radiotherapy according to the criteria defined by the International Bone Metastases Consensus Working Party. Eighty-seven patients were assessed. Twenty-four per cent of patients (95% confidence interval: 16-35%) were diagnosed as having pain with neuropathic features. On multivariate analysis, no significant correlations were seen between neuropathic pain features and patient characteristics. Sixty-four patients (74%) were assessable 2 months after the start of radiotherapy. Overall response rates were 59% (95% confidence interval: 33-82%) in patients with neuropathic features and 55% (95% confidence interval: 40-70%) in those without such features. A considerable proportion of the patients were proven to have bone pain with neuropathic features. Further investigations are warranted to validate symptom assessment tools in cooperation with pain distribution and image findings, and to

    We sought to determine the response rate and toxicity profile of sequential paclitaxel and bryostatin-1, a novel, selective inhibitor of protein kinase C, in patients with advanced esophageal cancer. Patients with advanced esophageal and gastroesophageal junction cancer were enrolled. All gave informed consent. They were initially treated with paclitaxel 90 mg/m(2) intravenously on Day 1 and bryostatin-1 50 microg/m2 on Day 2 weekly for three consecutive weeks out of four. Because of severe myalgias, dosing was reduced to paclitaxel 80 mg/m2 with bryostatin-1 40 microg/m2 and then to paclitaxel 80 mg/m2 with bryostatin-1 25 microg/m2. Twenty-four patients were enrolled, with 22 assessable for response. The partial response rate was 27%. 10 patients treated with bryostatin-1 40-50 microg/m2 had a response rate of 40 versus 17% at bryostatin-1 25 microg/m2 (p-value = 0.3). Median time-to-progression was 3.7 months and median survival was 8.3 months. Grade 3/4 myalgias were seen in 50% of patients. Myalgias appeared to be related to bryostatin-1 dose. Because of toxicity, the trial was closed prior to full accrual. Despite potential anti-tumor activity of this combination in patients with advanced esophageal cancer, further development is not warranted, given the severe toxicity, especially myalgias, that were seen.

  14. Computational Approaches to Consecutive Pattern Avoidance in Permutations

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

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

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

    Hepatectomies have been increasingly recommended and performed in Brazil; they present great differences related to immediate complications. Assessing the immediate postoperative complications in a series of 88 open liver resections. Prospective database of patients subjected to consecutive hepatectomies over nine years. The post-hepatectomy complications were categorized according to the Clavien-Dindo classification; complications presenting grade equal to or greater than 3 were considered major complications. Hepatic resections involving three or more resected liver segments were considered major hepatectomies. Eighty-four patients were subjected to 88 hepatectomies, mostly were minor liver resections (50 cases, 56.8%). Most patients had malignant diseases (63 cases; 71.6%). The mean hospitalization time was 10.9 days (4-43). Overall morbidity and mortality rates were 37.5% and 6.8%, respectively. The two most common immediate general complications were intra-peritoneal collections (12.5%) and pleural effusion (12.5%). Bleeding, biliary fistula and liver failure were identified in 6.8%, 4.5% and 1.1% of the cases, respectively, among the hepatectomy-specific complications. The patients operated in the second half of the series showed better results, which were apparently influenced by the increased surgical expertise, by the modification of the hepatic parenchyma section method and by the increased organ preservation.

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

    Directory of Open Access Journals (Sweden)

    Guang Li

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

    2014-01-01

    Objective Menstrual symptoms such as dysmenorrhea usually occur during the hormone-free interval in oral contraceptive users. Progestin withdrawal activates NF-κB transcription factor, which upregulates both vascular endothelial growth factor (VEGF) and Cox-2 expression in the endometrium. The use of natural NF-κB inhibitors such as pycnogenol may block this response, improving dysmenorrhea. Patients and methods Twenty-four patients with severe dysmenorrhea were allocated to one of two treatment groups. In Group A (n=13), women were treated with an oral contraceptive containing 15 μg of ethinyl estradiol and 60 mg of gestodene (Adoless®) in a 24/4 regimen for three consecutive cycles. Women in Group B (n=11) used the same contraceptive regimen together with 100 mg of pycnogenol (Flebon®) continuously for 3 months. Pain scores were graded using a visual analog scale (VAS) before and during the hormone-free interval at the end of the third treatment cycle. Results Before treatment, VAS pain scores for dysmenorrhea were 8 and 9 in Groups A and B, respectively. However, by the end of the third treatment cycle, pain scores had decreased significantly (Pgestodene. PMID:25525393

Methods From June 2009 to January 2012, 24 patients with polyostotic ifbrous dysplasia in the proximal femur were adopted and treated. There were 14 males and 10 females, whose average age was 24 years old ( range;8-61 years ). A combination of surgery and postoperative pamidronate disodium was performed on 11 patients, curettage, bone graft and internal ifxation on 8 patients, simple internal fixation on 3 patients and only pamidronate disodium on 13 patients. Pamidronate disodium was taken every 3 months after the operation or after the ifrst treatment, and the duration was 2 years. Before the treatment or before pamidronate disodium injection, bone metabolic markers were detected and the imaging examination was performed in all the patients, including osteocalcin ( OC ) and C-terminal telopeptides of type I collagen ( CTX-I ).The Visual Analogue Scale ( VAS ) was used to evaluate the preoperative and postoperative pain. The hip function was systematically assessed based on the Harris

    Hyperphosphatemia in chronic kidney disease (CKD) is associated with vascular calcification, cardiovascular morbidity and mortality. The aim of this study was to estimate the daily dietary phosphorus intake compared with recommendations in CKD patients and to evaluate the reproducibility of the 24-h urinary phosphorus excretion. Twenty CKD patients stage 3-4 from the outpatient clinic, collected 24-h urine and kept dietary records for 3 consecutive days. The mean daily phosphorus intake was 1367±499, 1642±815 and 1426±706 mg/day, respectively (P=0.57). The mean urinary phosphorus excretion was 914±465, 954±414 and 994±479 mg/day, respectively (P=0.21). In this population of CKD patients stage 3-4 the daily phosphorus intake was above the recommended. Twenty-four-hour urinary phosphorus excretion was reproducible and the data indicate that a single 24-h urine collection is sufficient to estimate the individual phosphorus excretion.European Journal of Clinical Nutrition advance online publication, 14 December 2016; doi:10.1038/ejcn.2016.247.

    Medial patellofemoral ligament (MPFL) reconstruction has recently been broadly accepted as primary surgical treatment in adults. Reconstruction techniques with osseous fixation in femur cannot be used for patients with open growth plates. Operative treatment of patella instability in children therefore is a challenge and requires alternative MPFL reconstruction techniques. Limited knowledge exists concerning outcome after MPFL reconstruction in children and adolescents. This study present clinical outcome in a consecutive single clinic series of children treated with paediatric MPFL reconstruction using a soft tissue femoral fixation technique. Twenty-four MPFL reconstructions in 20 operated children aged 8-16 were included in the study. Indication for surgery was two or more patella dislocations. MPFL reconstruction was performed by looping the released gracilis tendon around the adductor magnus tendon insertion and through drill holes in the proximal medial patella edge. Clinical outcome was evaluated by Kujala score and NRS pain score preoperatively, at 1-year follow-up and final follow-up at 39 months. Outcome was compared with a cohort of 179 adult patients with recurrent patella instability operated with an adult MPFL reconstruction technique. Kujala score improved from 61 (13) to 81 (16). NRS pain score improved from 3.0 (3.1) to 1.5 (1.3) in activity. Four patients (20%) experienced redislocation within the first postoperative year compared with 5% in an adult patient population. Five patients (25%) experienced subluxations. One patient with a redislocation was re-operated with adult MPFL reconstruction technique. Cartilage injury was seen in six patients. There are clinical relevant improvements in knee function and pain after MPFL reconstruction in paediatric patients. Patella stability after MPFL reconstruction using femoral soft tissue graft fixation in paediatric patients was inferior to MPFL reconstruction using bony femoral fixation in adult patients

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

    A percentage of patients with symptoms of irritable bowel syndrome (IBS) suffer from food hypersensitivity (FH) and improve on a food-elimination diet. No assays have satisfactory levels of sensitivity for identifying patients with FH. We evaluated the efficacy of an in vitro basophil activation assay in the diagnosis of FH in IBS-like patients. Blood samples were collected from 120 consecutive patients diagnosed with IBS according to Rome II criteria. We analyzed in vitro activation of basophils by food allergens (based on levels of CD63 expression), as well as total and food-specific immunoglobulin (Ig)E levels in serum. Effects of elimination diets and double-blind food challenges were used as standards for FH diagnosis. Twenty-four of the patients (20%) had FH (cow's milk and/or wheat hypersensitivity); their symptom scores improved significantly when they were placed on an elimination diet. Patients with FH differed from other IBS patients in that they had a longer duration of clinical history, a history of FH as children, and an increased frequency of self-reported FH; they also had hypersensitivities to other antigens (eg, egg or soy). The basophil activation assay diagnosed FH with 86% sensitivity, 88% specificity, and 87% accuracy; this level of sensitivity was significantly higher than that of serum total IgE or food-specific IgE assays. A cytometric assay that quantifies basophils after stimulation with food antigens based on cell-surface expression of CD63 had high levels of sensitivity, specificity, and accuracy in diagnosing FH. This assay might be used to diagnose FH in patients with IBS-like symptoms. Copyright 2010 AGA Institute. Published by Elsevier Inc. All rights reserved.

    @@ "Xiongbi" chest (or precordial) pain with stuffiness, or chest pain syndrome is referred to choking pain in the chest due to stagnation of chest -yang, failure of qi and blood in warming and nourishing the local meridians. It is usually caused by stagnation of dampness and phlegm in the interior, or by insufficiency of qi and blood stasis, leading to impeded flow of qi and blood in the heart vessels. Its pathological characteristics are deficiency (chest-yang) in origin and excess (i. e., qi stagnation) in superficiality. The therapeutic principles are promoting blood circulation to remove blood stasis, getting rid of blockage and dredging the passages of yang-qi.

    Eighty questionnaires were sent to parents and/or caregivers of autistic persons diagnosed between 1960-73 at CPRI, a regional assessment and treatment centre. The objective was to determine their present place of residence, functioning ability, language development, program involvement, and seizure activity. The results of this study support evidence that more than 50 percent require long-term institutional care; almost one-third suffer epileptic seizures; there is a persistence of symptoms and difficulty in gaining useful speech; few live independently or are capable of employment.

    Full Text Available The objective of this study was to determine time trends (1982–2006 in total fat intake and changes in fatty acid structure intake in adolescents from Warsaw in view of increasing prevalence of obesity. Data come from four successive surveys randomly selected samples of adolescents (aged 11–15 years old, from Warsaw region. In total 9747 pupils have been examined, with response rate varying from 55% to 87% depending on year. Surveys were done always in the spring season of the year. Food intake was assessed by using 24 hours recall method of consumption by the pupils all products, including enriched, dishes and beverages as well as diet supplements, in the last 24 hours preceding the examination. The content of energy and nutrients was calculated by means of own computer softwares (DIET 2 and 4, taking into account successive revisions of the tables of food composition and nutritional values, as well as current Polish DRI. A significant decreasing trend was found in intake of total fat, of saturated fatty acids (SFA and cholesterol. The percentage of energy from total fat, also decreased both in boys (to 35,1% and girls (to 33,7%, what failed to reach the desired level below 30% of energy from fat which is recommended. Also significant decrease of SFA consumption was not satisfactory enough to approach the values <10% of energy recommended as was from 13% to 15%. Decreasing trends in fat intake was not in accordance with the trend in obesity prevalence in the adolescents as average BMI is going up. To stabilize the health-oriented changes especially in the diets of adolescents, further activity is desired from professionals working with prevention of adolescents obesity.

    Obstructive sleep apnea causes intermittent elevation of systemic blood pressure (BP) during sleep. To determine whether obstructive apnea in children has a tonic effect on diurnal BP, 24-hour ambulatory blood pressure was obtained from 60 children with mean age of 10.8 +/- 3.5 years. Thirty-nine children had obstructive apnea and 21 had primary snoring. Children with obstructive apnea had significantly greater mean BP variability during wakefulness and sleep, a higher night-to-day systolic BP, and a smaller nocturnal dipping of mean BP. Variability of mean arterial pressure during wakefulness was predicted by the desaturation, body mass, and arousal indices, whereas variability during sleep was predicted by apnea-hypopnea and body mass indices. Nocturnal BP dipping was predicted by the desaturation index. There were no significant differences in systolic, diastolic, or mean arterial BP during sleep between the groups. Diastolic BP during wakefulness was significantly different between the groups and correlated negatively with apnea-hypopnea index. We conclude that obstructive apnea in children is associated with 24-hour BP dysregulation and that, independent of obesity, the frequency of obstructive apnea, oxygen desaturation, and arousal contributes to abnormal BP control.

    2017-05-01

    Full Text Available A 24-year-old woman presented with a 5-month history of a left flank mass that was painful on palpation. Magnetic resonance imaging revealed a 10.0 × 6.0 × 2.5 cm mass consistent with lipoma. A fatty lobulated mass was excised and subjected to H&E staining and immunohistochemical analyses. The specimen consisted of mature univacuolated adipocytic cells, with intermixed multivacuolated eosinophilic granular cells. No atypia or hyperchromasia was identified. Most of the cells were S100 positive and Ki-67 immunonegative. A diagnosis of a lipoma-like hibernoma was rendered. Hibernomas are rare benign lipomatous tumors that show differentiation toward brown fat. The lipoma-like hibernoma subtype is rare and can be misdiagnosed as atypical lipoma or well-differentiated liposarcoma. Here we describe an example of this rare tumor.

    A 1985 plutonium puncture wound resulted in the initial deposition of 48 kBq of transuranic alpha activity, primarily 239+240Pu and 241Am, in a worker's right index finger. Surgical excisions in the week following reduced the long-term residual wound activity to 5.4 kBq, and 164 DTPA chelation therapy administrations over 17 mo resulted in urinary excretion of about 7 kBq. The case was published in 1988, but now 24 y of follow-up data are available. Annual bioassays have included in-vivo measurements of 241Am in the wound, skeleton, liver, lung, and axillary lymph nodes, and urinalyses for plutonium and 241Am. These measurements have shown relatively stable levels of 241Am at the wound site, with gradually increasing amounts of 241Am detected in the skeleton. Liver measurements have shown erratic detection of 241Am, and the lung measurements indicate Am but as interference from activity in the axillary lymph nodes and skeleton rather than activity in the lung. Urine excretion of Pu since termination of chelation therapy has typically ranged from 10 to 20 mBq d, with Am excretion about 10% of that for 239+240Pu. Annual routine medical exams have not identified any adverse health effects associated with the intake.

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

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

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

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

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

    Full Text Available Objective: Information about antibiotic prescription patterns for cystic fibrosis (CF patients and, specifically, about inhaled treatment strategies for their management is lacking in Spain due to the absence of a national patient registry. In this study we present data about antibiotic prescription in the Spanish CF context that were obtained in a multicenter study, being inhaled treatment strategies the special focus of this work.Methods: Twenty-four specialized CF units (12 adult, 12 pediatric from 17 tertiary- care hospitals covering all Spanish Autonomous Communities provided sputa and clinical data from 15 consecutive patients. Data about antibiotic and non-antibiotic therapies prescribed to these patients during the year prior inclusion (2013 were retrospectively collected.Results: The multicenter study included 341 CF patients from all age groups and clinical status. The prevalence of oral, inhaled and intravenous therapies was 89% (n = 302, 80% (n = 273 and 31% (n = 105, respectively. The most prevalent oral agents were ciprofloxacin (n = 177, 59%, cotrimoxazole (n = 109, 36% and amoxicillin-clavulanate (n = 99, 33%, whereas ceftazidime (n = 53, 50%, tobramycin (n = 43, 41% and meropenem (n = 41, 49% were the most prevalent intravenous ones. Two or more different inhaled antibiotics were administered to 67 patients (24%, 51 of them receiving 2 drugs continuously in alternating schemes. Nebulization of intravenous specific antibiotics was common (n = 39 and, in some cases, was used for maintenance purposes.Conclusions: These results show that the treatment of CF patients is evolving more rapidly than clinical consensus guidelines. Clinical trials evaluating new specific inhaled combinations and new alternative treatment regimes of the existing ones are needed.

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

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

  4. Phase I Oncology Studies: Evidence That in the Era of Targeted Therapies, Patients on Lower Doses Do Not Fare Worse

    PURPOSE To safely assess new drugs, cancer patients in initial cohorts of phase I oncology studies receive low drug doses. Doses are successively increased until the maximum tolerated dose (MTD) is determined. Since traditional chemotherapy is often more effective near the MTD, ethical concerns have been raised regarding administration of low drug doses to phase I patients. However, a substantial portion of oncology trials now investigate targeted agents, which may have different dose-response relationships than cytotoxic chemotherapies. EXPERIMENTAL DESIGN Twenty-four consecutive trials treating 683 patients between 10-01-2004 and 6-30-2008 at MD Anderson Cancer Center were analyzed. Patients were assigned to a low-dose (≤25% MTD), medium-dose (25–75% MTD), or high-dose (≥75% MTD) group, and groups were compared for response rate, time-to-treatment-failure, progression-free survival, overall survival, and toxicity. To remove negatively biasing data from the high-dose group, in a second analysis patients treated above the MTD were excluded (high-dose group = 75–100% MTD). 97.7% of patients received targeted agents. RESULTS Even when excluding patients above the MTD, there was an early trend favoring the low- versus high-dose group in time-to-treatment-failure, with 32.9% versus 25.2% of patients on therapy at 3 months (p=0.08). Additionally, the low-dose group fared at least as well as the other groups in all other outcomes, including response rate, progression-free survival, overall survival, and toxicity. CONCLUSIONS These data may help alleviate concerns that patients who receive low drug doses on contemporary phase I oncology trials fare worse, and suggest targeted agents may have different dose-response relationships than cytotoxic chemotherapies.

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

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

  7. The $k$-Tuple Jumping Champions among Consecutive Primes

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

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

    The purpose of our study was to assess safety and efficacy of cataract surgery (CS) under topical anesthesia alone, i.e. without pre-anesthetic evaluation and without direct presence of an anesthesiologist. To this end we assessed the incidence of patients' preoperative anxiety, perioperative adverse events and patients' and surgeons' satisfaction. Patients undergoing CS under topical anesthesia over a one-month period were included. An anesthesiologist and nurse anesthetist were present in the area and could intervene in case of an adverse event. Patients' anxiety was scored using the Amsterdam Preoperative Anxiety & Information Scale (APAIS), and their satisfaction with the Iowa Satisfaction with Anesthesia Scale (ISAS). Surgeons' satisfaction was scored with a VAS from 0 to 10 (0: surgery not possible & 10: excellent surgical conditions). One hundred and twenty-four consecutive patients were included; mean age was 71 (±9.4) years. Mean APAIS I was 6.4/20 (±3.7). Mean APAIS II was 3.1 (±1.8). Mean ISAS score was 5.5/6 (±0.6), indicating high patient satisfaction. Surgeon satisfaction score was 8.9/10 (±1.7). Twenty-three adverse events occurred of which 16 required interventions by the anaesthesiologist or surgeon: 5 supplemental local or regional anaesthesia, 6 iv-analgesia, 5 management of hypertension. These preliminary data suggest that a simplified topical anesthesia protocol for ambulatory CS appears to be feasible and safe, as long as an anesthesia team is present in the area to intervene if needed.

    Full Text Available Unlike experimental studies indicating a neuroprotective property of uric acid, clinical studies have shown that elevated levels of uric acid are associated with a risk of ischemic stroke. However, the association of uric acid with cerebral hemorrhage has seldom been tested. We aimed to elucidate the association between uric acid and cerebral microbleeds (CMBs, a hemorrhage-prone cerebral microangiopathy. Seven hundred twenty-four patients with ischemic stroke who were consecutively admitted to our hospital were included in this study. We collected demographic, clinical, and laboratory data, including uric acid level, and examined the presence of CMBs using T2*-weighted gradient-echo MRI. We used logistic regression analysis to examine an independent association between uric acid and CMBs. Two-hundred twenty-six patients had CMBs (31.2%. After adjusting for possible confounders, elevated uric acid was independently associated with the presence of CMBs (the highest quartile vs. lowest quartile, adjusted odd ratio [OR], 1.98; 95% confidence interval [CI], 1.16-3.39. This association retained in patients with deep or infratentorial CMBs (with or without lobar CMBs but not among those with lobar CMBs. In addition, this association was robust among patients with hypertension (the highest quartile vs. lowest quartile, adjusted OR, 2.74; 95% CI, 1.43-5.24. In contrast, we did not find the association in patients without hypertension. We demonstrated that serum uric acid is independently associated with the presence of CMBs. In particular, the relation between uric acid and CMBs was robust in hypertensive patients.

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

    2012-11-01

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

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

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

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

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

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

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

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

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

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

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

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

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

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

    Full Text Available BACKGROUND: Memory disturbances, in particular episodic verbal memory dysfunction, are the most frequent cognitive impairment observed in multiple sclerosis (MS patients. The use of self-reported outcomes for evaluating treatment and managing care of these subjects has been questioned. The aim of this study was to provide new evidence about the suitability of self-reported outcomes for use in this impaired population by exploring the internal structure, reliability and external validity of a specific quality of life (QoL instrument, the Multiple Sclerosis International Quality of Life questionnaire (MusiQoL. METHODS: DESIGN: cross-sectional study. INCLUSION CRITERIA: MS patients of any disease subtype. DATA COLLECTION: sociodemographic (age, gender, marital status, education level, and occupational activity and clinical data (MS subtype, Expanded Disability Status Scale, disease duration; QoL (MusiQoL and SF36; and memory performance (Grober and Buschke test. In accordance with the French norms of the memory test, non-impaired and impaired populations were defined for short- and long-delay free composites and for short- and long-delay total composites. For the 8 populations, psychometric properties were compared to those reported from the reference population assessed in the validation study. PRINCIPAL FINDINGS: One hundred and twenty-four consecutive patients were enrolled. The analysis performed in the impaired populations showed that the questionnaire structure adequately matched the initial structure of the MusiQoL. The unidimensionality of the dimensions was preserved, and the internal/external validity indices were close to those of the reference population. CONCLUSIONS/SIGNIFICANCE: Our study suggests that memory dysfunction did not compromise the reliability or validity of the self-reported QoL questionnaires.

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

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

    Cystic fibrosis (CF) patients have abnormally viscid bronchial secretions that cause airway obstruction, inflammation, and infection that leads to lung damage. To enhance airway clearance and reduce airway obstruction, daily bronchopulmonary hygiene therapy is considered essential. Compare the effectiveness of and patient preferences regarding 3 airway clearance methods: postural drainage and percussion (PD&P), intrapulmonary percussive ventilation (IPV), and high-frequency chest wall compression (HFCWC). The participants were hospitalized CF patients >or= 12 years old. Effectiveness was evaluated by measuring the wet and dry weights of sputum obtained with each method. In random order, each patient received 2 consecutive days of each therapy, delivered 3 times daily for 30 minutes. Sputum was collected during and for 15 minutes after each treatment, weighed wet, then dried and weighed again. Participants rated their preferences using a Likert-type scale. Mean weights and preferences were compared using analysis of variance with repeated measures. Patient preferences were compared using Freidman's test. Twenty-four patients were studied. The mean +/- SD wet sputum weights were 5.53 +/- 5.69 g with PD&P, 6.84 +/- 5.41 g with IPV, and 4.77 +/- 3.29 g with HFCWC. The mean wet sputum weights differed significantly (p = 0.035). Wet sputum weights from IPV were significantly greater than those from HFCWC (p < 0.05). The mean dry sputum weights were not significantly different. With regard to overall preference and to the subcomponents of preference, none of the 3 methods was preferred over the others. HFCWC and IPV are at least as effective as vigorous, professionally administered PD&P for hospitalized CF patients, and the 3 modalities were equally acceptable to them. A hospitalized CF patient should try each therapy and choose his or her preferred modality.

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

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

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

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

    2003-09-01

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

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

    In 2006 the European League Against Rheumatism (EULAR) proposed new classification criteria for Henoch-Schönlein purpura (HSP). We aimed to establish the applicability of these criteria in patients with primary cutaneous vasculitis (CV). We also compared these criteria with previously established classification criteria for HSP. A series of 766 (346 women/420 men; mean age 34 years) consecutive unselected patients with CV was assessed. One hundred and twenty-four of them with secondary CV or with CV associated with other well defined entities were excluded from the analysis. The 2006 EULAR criteria for HSP were tested in the remaining 642 patients with primary CV. Two sets of criteria for HSP were used for comparisons: a) the 1990 American College of Rheumatology (ACR-1990), and b) the ACR modified criteria proposed by Michel et al. in 1992 (Michel-1992). 451 (70.2%) of 642 patients were classified as having HSP according to the EULAR-2006 criteria, 405 (63.1%) using the ACR-1990 criteria, and 392 (61.1%) by the Michel-1992 criteria. However, only 336 patients (52.3%) met at the same time the EULAR-2006 and the ACR-1990 criteria, and only 229 patients (35.7%) fulfilled both the EULAR-2006 and Michel-1992 criteria. It is noteworthy that only 276 (43%) patients met the three set of criteria. Children fulfilled all the sets of criteria more commonly than adults (215 [66.6%] of 323 vs. 61 [19%] of 319, respectively; pEULAR-2006 criteria show low concordance with previous sets of classification criteria used for HSP.

    Full Text Available BACKGROUND: Cognitive impairment occurs in about 50% of multiple sclerosis (MS patients, and the use of self-reported outcomes for evaluating treatment and managing care among subjects with cognitive dysfunction has been questioned. The aim of this study was to provide new evidence about the suitability of self-reported outcomes for use in this specific population by exploring the internal structure, reliability and external validity of a specific quality of life (QoL instrument, the Multiple Sclerosis International Quality of Life questionnaire (MusiQoL. METHODS: DESIGN: cross-sectional study. INCLUSION CRITERIA: MS patients of any disease subtype. DATA COLLECTION: sociodemographic (age, gender, marital status, education level, and occupational activity and clinical data (MS subtype, Expanded Disability Status Scale, disease duration; QoL (MusiQoL and SF36; and neuropsychological performance (Stroop color-word test. STATISTICAL ANALYSIS: confirmatory factor analysis, item-dimension correlations, Cronbach's alpha coefficients, Rasch statistics, relationships between MusiQoL dimensions and other parameters. PRINCIPAL FINDINGS: One hundred and twenty-four consecutive patients were enrolled. QoL scores did not differ between the 69 cognitively non-impaired patients and the 55 cognitively impaired patients, except for the symptoms dimension. The confirmatory factor analysis performed among the impaired subjects showed that the structure of the questionnaire matched with the initial structure of the MusiQoL. The unidimensionality of the MusiQoL dimensions was preserved, and the internal validity indices were satisfactory and close to those of the reference population. CONCLUSIONS/SIGNIFICANCE: Our study suggests that executive dysfunction did not compromise the reliability and the validity of the self-reported QoL questionnaires.

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

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

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

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

    2014-01-01

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

    To identify those clinical characteristic and arthroscopic findings in patients with knee arthrosis that are associated with worsening of the disease and subsequent total knee arthroplasty (TKA). A retrospective, descriptive study was conducted on 78 consecutive patients (88 knees) who underwent knee arthroscopy for arthrosis. The study included 44 women and 34 men, with a mean age of 58.9 years (range: 37-78 years). After a mean follow-up of 50.4 months (range: 12-96 months), those patients who progressed towards TKA were identified. A logistic regression model was applied to recognise the factors associated with deterioration of the arthrosis, with consequent progression towards a TKA. Twenty-four out of the 88 knees progressed towards a TKA (27.3%) within a mean time of 13.5 months after arthroscopy (range: 13-29 months). The clinical characteristics that showed a significant association with poor progression of the arthrosis were: female gender (0.02) and Ahlbäck 2 (P=.04). Arthroscopic finding that proved significant correlation with worsening of the arthrosis towards TKA were: meniscal tears of the posterior horn (P=.02), meniscectomies above 60% (P=.03), and 2nd degree chondral lesions in loading areas of the medial femoral condyle (P=.02). The variables associated with a greater chance of progressing towards a TKA after a knee arthroscopy due to arthrosis in this study were, female gender, grade 2 radiographic arthrosis, posterior horn meniscal lesions, meniscectomies over 60%, and chondral lesions in loading area of the medial femoral condyle.

    This is a retrospective review of 25 patients with severe lumbar nerve root compression undergoing multilevel anterior retroperitoneal lumbar interbody fusion and posterior instrumentation for deformity. The objective is to analyze the outcomes and clinical results from anterior interbody fusions performed through a lateral approach and compare these with traditional surgical procedures. A consecutive series of 25 patients (78 extreme lateral interbody fusion [XLIF] levels) was identified to illustrate the primary advantages of XLIF in correcting the most extreme of the 3-dimensional deformities that fulfilled the following criteria: (1) a minimum of 40° of scoliosis; (2) 2 or more levels of translation, anterior spondylolisthesis, and lateral subluxation (subluxation in 2 planes), causing symptomatic neurogenic claudication and severe spinal stenosis; and (3) lumbar hypokyphosis or flat-back syndrome. In addition, the majority had trunks that were out of balance (central sacral vertical line ≥2 cm from vertical plumb line) or had sagittal imbalance, defined by a distance between the sagittal vertical line and S1 of greater than 3 cm. There were 25 patients who had severe enough deformities fulfilling these criteria that required supplementation of the lateral XLIF with posterior osteotomies and pedicle screw instrumentation. In our database, with a mean follow-up of 24 months, 85% of patients showed evidence of solid arthrodesis and no subsidence on computed tomography and flexion/extension radiographs. The complication rate remained low, with a perioperative rate of 2.4% and postoperative rate of 12.2%. The lateral listhesis and anterior spondylolisthetic subluxation were anatomically reduced with minimally invasive XLIF. The main finding in these 25 cases was our isolation of the major indication for supplemental posterior surgery: truncal decompensation in patients who are out of balance by 2 cm or more, in whom posterior spinal osteotomies and segmental

    Background The demand for specialized medical services such as critical care often exceeds availability, thus rationing of intensive care unit (ICU) beds commonly leads to difficult triage decisions. Many factors can play a role in the decision to admit a patient to the ICU, including severity of illness and the need for specific treatments limited to these units. Although triage decisions would be based solely on patient and institutional level factors, it is likely that intensivists make different decisions when there are fewer ICU beds available. The objective of this study is to evaluate the characteristics of patients referred for ICU admission during times of limited beds availability. Methods A single center, prospective, observational study was conducted among consecutive patients in whom an evaluation for ICU admission was requested during times of ICU overcrowding, which comprised the months of April and May 2014. Results A total of 95 patients were evaluated for possible ICU admission during the study period. Their mean APACHE-II score was 16.8 (median 16, range 3 - 36). Sixty-four patients (67.4%) were accepted to ICU, 18 patients (18.9%) were triaged to SDU, and 13 patients (13.7%) were admitted to hospital wards. ICU had no beds available 24 times (39.3%) during the study period, and in 39 opportunities (63.9%) only one bed was available. Twenty-four patients (25.3%) were evaluated when there were no available beds, and eight of those patients (33%) were admitted to ICU. A total of 17 patients (17.9%) died in the hospital, and 15 (23.4%) expired in ICU. Conclusion ICU beds are a scarce resource for which demand periodically exceeds supply, raising concerns about mechanisms for resource allocation during times of limited beds availability. At our institution, triage decisions were not related to the number of available beds in ICU, age, or gender. A linear correlation was observed between severity of illness, expressed by APACHE-II scores, and the

    The purpose of this study was to evaluate the results of osseous genioplasty with bimaxillary orthognathic surgery. A retrospective consecutive case series of patients treated by a single surgeon between 2004 and 2013 was studied. All underwent Le Fort I, sagittal ramus osteotomies, septoplasty, inferior turbinate reduction, and osseous genioplasty. The outcome variables included the presenting chin dysmorphology, complications, and assessment of morphologic change. A Steiner analysis was completed for each subject's interval cephalogram. Two hundred sixty-two subjects met the inclusion criteria. Their mean age at operation was 25 (range 13-63) years. Chin osteotomy complications included one wound infection (0.4%), and two of the 1572 mandibular anterior teeth at risk sustained a pulpal injury. None of the subjects required revision. For subjects undergoing chin advancement, the mean change was +3.5 (range +3 to +6) mm. A majority also underwent counterclockwise rotation of the mandible (62%). For those undergoing chin lengthening, the mean change was +5 (range +3 to +12mm) mm, and for those undergoing vertical shortening, the mean change was -3.5 (range -3 to -7) mm. Osseous genioplasty is confirmed to be a safe method to reshape the chin. When osseous genioplasty is performed in conjunction with bimaxillary orthognathic surgery, only a modest horizontal change is required to achieve the preferred pogonion projection.

    Full Text Available In tropical countries like Bangladesh, persons are bitten by snakes every day and a considerable number of patients die en route to the hospital. An event of consecutive neurotoxic bites on two men by a single snake was observed in the Snake Bite Study Clinic (SBSC of the Chittagong Medical College Hospital (CMCH. Two brothers, working in their semi-pucca restaurant, were successively bitten by the same cobra on their lower limbs. Within an hour, they were taken to the CMCH. Few minutes after admission, both developed symptoms of neurotoxicity: ptosis, nasal voice, dysphagia, broken neck sign, etc. They received polyvalent antivenom (Haffkine Bio-Pharmaceuticals Company, India and other auxiliary treatment immediately. Within few hours, neurotoxic features were completely absent. Later, the snake was captured in the restaurant kitchen and identified as monocellate cobra (Naja kauthia by the SBSC. The elder brother developed significant antivenom reactions and both presented necrosis and ulceration at the bite sites. In these cases, immediate arrival to the hospital and early administration of antivenom resulted in successful recoveries.

    Background Military recruits are at a higher risk of acute respiratory disease (ARD) and the causative agents might change over time, which needs to be investigated. Methods The nasopharyngeal swabs and blood samples were consecutively collected from conscripts for three years in a military training center. The real-time lfuorescent quantitative PCR assays were conducted for 15 species of common respiratory pathogens; the serum anti-Legionella pneumophila antibodies were detected by indirect immunolfuorescence (IIF) assay, and serum anti-Microplasma pneumoniae antibodies, serum anti-in-lfuenza B virus and anti-inlfuenza A virus-IgM and IgG were detected by ELISA. Results The prevalences of ARD were 59.3% (108/182) in 2008, 23.3% (50/215) in 2009,and 19.6% (40/204) in 2010. Among the patients with ARD from 2008 to 2010, the inlfuenza B virus infection accounted for 45.4%, 30.0% and 55.0%, and seasonal inlfuenza A virus infection for 8.3%, 8.0% and 5.0%, respectively; the positive rates of serum anti-Legionella pneumophila and anti-Microplasma pneumoniae antibodies in recruits was lower than 10% each year respectively in the three years without diagnostic signiifcance. Conclusion The early appropriate diagnosis and treatment of ARD in military personnel will ensure the power strength of armed forces.

    Purpose: To report toxicity and overall survival (OS) in patients with newly diagnosed glioblastoma multiforme (GBM) treated with hypofractionated intensity-modulated radiotherapy (hypo-IMRT) with concurrent and adjuvant temozolomide (TMZ). Methods and Materials: Patients with newly diagnosed GBM after biopsy or resection and with adequate performance status and organ or bone marrow function were eligible for this study. Patients received postoperative hypo-IMRT to the surgical cavity and residual tumor seen on T1-weighted brain MRI with a 5-mm margin to a total dose of 60 Gy in 10 fractions (6 Gy/fraction) and to the T2 abnormality on T2-weighted MRI with 5-mm margin to 30 Gy in 10 fractions (3 Gy/fraction). Concurrent TMZ was given at 75 mg/m{sup 2}/day for 28 consecutive days. Adjuvant TMZ was given at 150 to 200 mg/m{sup 2}/day for 5 days every 28 days. Toxicities were defined using Common Terminology Criteria for Adverse Events version 3.0. Results: Twenty-four patients were treated, consisting of 14 men, 10 women; a median age of 60.5 years old (range, 27-77 years); and a median Karnofsky performance score of 80 (range, 60-90). All patients received hypo-IMRT and concurrent TMZ according to protocol, except for 2 patients who received only 14 days of concurrent TMZ. The median number of adjuvant TMZ cycles was 6.5 (range, 0-14).With a median follow-up of 14.8 months (range, 2.7-34.2 months) for all patients and a minimum follow-up of 20.6 months for living patients, no instances of grade 3 or higher nonhematologic toxicity were observed. The median OS was 16.6 months (range, 4.1-35.9 months). Six patients underwent repeated surgery for suspected tumor recurrence; necrosis was found in 50% to 100% of the resected specimens. Conclusion: In selected GBM patients, 60 Gy hypo-IMRT delivered in 6-Gy fractions over 2 weeks with concurrent and adjuvant TMZ is safe. OS in this small cohort of patients was comparable to that treated with current standard of care

    Since the advent of epinephrine-containing wetting solutions and sophisticated fluid management techniques, increasingly larger and larger volumes of liposuction aspirations have been reported. Unfortunately, with these larger volumes of liposuction being routinely performed, greater rates of complications have also been reported, with the worst of these resulting in deaths. In a response to the increasing concerns over the safety of large-volume liposuction, a critical review of the senior author's own series has been performed to evaluate risks and benefits and to recommend guidelines for safe and effective large-volume liposuction. A retrospective chart review was performed on 631 consecutive patients who underwent liposuction procedures of at least 3000 cc total aspirate. All procedures were performed by the same senior surgeon between January of 1986 and March of 1998. Before September of 1996, traditional liposuction techniques were used. After September of 1996, ultrasound-assisted liposuction was performed. The superwet technique of fluid management was employed for all procedures performed after 1991. The particulars of the surgical and anesthetic techniques used are reviewed in the article. Data collection included preoperative patient demographics, preoperative and postoperative weights and measurements, and preoperative and postoperative photographs. Total aspirate volumes, fluid intakes, and fluid outputs were measured, and all complications were tallied. Average follow-up was 1 year. Results showed the majority of patients to be women, aged 17 to 74 years old. Of the preoperative weights, 98.7 percent were within 50 pounds of ideal chart weight. Total aspirate volumes ranged from 3 to 17 liters, with 94.5 percent of these under 10 liters. Fluid balance measurements showed an average of 120 cc/kg positive fluid balance at the end of the procedure, with none of these patients experiencing any significant fluid balance abnormalities.

    Total lymphoid irradiation was administered to 32 patients with intractable rheumatoid arthritis. Twenty-four patients showed at least a 25% improvement in 3 of 4 disease activity parameters, which persisted during the followup period of up to 48 months. Eight of the 32 patients required adjunctive immunosuppressive drug therapy to maintain improvement. Four patients died after total lymphoid irradiation; the causes of death were acute myocardial infarction (1 patient), pulmonary embolism (1 patient), and rheumatoid lung disease complicated by respiratory infection (2 patients). After therapy, patients exhibited a prolonged reduction in the number and function of circulating T helper cells.

  12. Trabecular reorganization in consecutive iliac crest biopsies when switching from bisphosphonate to strontium ranelate treatment.

    Full Text Available BACKGROUND: Several agents are available to treat osteoporosis while addressing patient-specific medical needs. Individuals' residual risk to severe fracture may require changes in treatment strategy. Data at osseous cellular and microstructural levels due to a therapy switch between agents with different modes of action are rare. Our study on a series of five consecutively taken bone biopsies from an osteoporotic individual over a six-year period analyzes changes in cellular characteristics, bone microstructure and mineralization caused by a therapy switch from an antiresorptive (bisphosphonate to a dual action bone agent (strontium ranelate. METHODOLOGY/PRINCIPAL FINDINGS: Biopsies were progressively taken from the iliac crest of a female patient. Four biopsies were taken during bisphosphonate therapy and one biopsy was taken after one year of strontium ranelate (SR treatment. Furthermore, serum bone markers and dual x-ray absorptiometry measurements were acquired. Undecalcified histology was used to assess osteoid parameters and bone turnover. Structural indices and degree of mineralization were determined using microcomputed tomography, quantitative backscattered electron imaging, and combined energy dispersive x-ray/µ-x-ray-fluorescence microanalysis. CONCLUSIONS/SIGNIFICANCE: Microstructural data revealed a notable increase in bone volume fraction after one year of SR treatment compared to the bisphosphonate treatment period. Indices of connectivity density, structure model index and trabecular bone pattern factor were predominantly enhanced indicating that the architectural transformation from trabecular rods to plates was responsible for the bone volume increase and less due to changes in trabecular thickness and number. Administration of SR following bisphosphonates led to a maintained mineralization profile with an uptake of strontium on the bone surface level. Reactivated osteoclasts designed tunneling, hook-like intratrabecular

    Full Text Available Purpose: To analyze the complications and their managements in Descemet′s stripping endothelial keratoplasty (DSEK in consecutive 430 cases by single surgeon in a tertiary eye hospital. Materials and Methods: 430 eyes of 366 patients with endothelial dysfunctions scheduled for DSEK, were analyzed retrospectively. In all cases donor dissection was performed manually, and ′Taco′ insertion and unfolding technique was used. Intra-operative and postoperative complications with their managements and outcomes were reviewed retrospectively. Periodic endothelial cell density was analyzed for each patient till the last visit. Follow-up period was between 3 to 60 months (mean 18.7 months. Results: 13 (3.0% eyes had operative complications during donor dissection and 16 (3.7% had during recipient procedure. In 7 (1.6% eyes, donor lenticule was replaced with a new one during the surgery. In early postoperative period, 21 (4.9% eyes had donor dislocation and 12 (2.8% eyes had air-induced pupillary block; and they were managed immediately. 2 cases had primary graft failure and in 1 case had postoperative bacterial endophthalmitis requiring evisceration. In late postoperative period, 48 (11.3% eyes had secondary glaucoma and 14 (3.3% eyes had late secondary graft failure. Endothelial rejection occurred in 5 (1.2% cases. Mean endothelial cell loss was 19.7% after 3 months and 54.2% after 5 years. Total graft failure in this series was 31 (7.2% and in 17 cases re-DSEK was performed successfully. Conclusions: Both operative and postoperative complications do occur in DSEK. Most of these complications can be managed by medical or appropriate surgical means. Some of the complications can be avoided and reduced with experience.

    A young lady with a rare Bombay (Oh) blood group had two successive uneventful pregnancies. Her serum contained a potent high-titre anti-H and serological as well as chemiluminescence tests, suggesting that the antibody was haemolytic. Her husband was of the normal H status. Theoretically, both babies should have been positive for the H antigen and should have suffered from haemolytic disease of the newborn. This apparent conundrum could be owing to the weak expression of the H antigens on the infant red cells.

    Background The true risk of choronic villus sampling (CVS) is poorly defined. The objective of this study was to review the clinical outcome of transabdominal CVS performed in a university teaching unit, with an emphasis on the complication rate.Methods A comprehensive audit database was maintained for 1351 pregnant women, including 17 sets of twin pregnancies, who had a CVS. Details and outcome of all CVSs made in the unit between May 1996 and May 2004 were reviewed. All CVSs were performed by one of 5 operators using the identical techniques.Results All procedures were performed transabdominally. A total of 1355 CVSs were performed because there were 4 dichorionic twin pregnancies which required 2 punctures. The mean gestation at CVS was (11.8±0.7) weeks, and 97.3% of the procedures were performed between 11 and 13 completed weeks. The majority (96.2%) required only 1 puncture to achieve correct needle placement. The procedure failed to obtain an adequate sample in 4 subjects (0.30%). A total of 1351 chromosomal studies were requested and there was 1 case (0.07%) of culture failure. The results of chromosomal studies were available within 14 days in 36.7% of the cases and within 21 days in 94.0%. Overall, 77 chromosomal abnormalities (5.7%) and 5 cases of thalassemia major were detected. Pregnancy outcome was unknown in only 13 singleton subjects (0.96%). In the remaining 1355 fetuses, there were 76 pregnancy terminations (5.56%), 10 fetal losses with obvious obstetric causes (0.73%), and 21 potentially procedure-related fetal losses (1.54%). In the last group, the majority had one or more co-existing obstetric complications. The background fetal loss rate for pregnancies at similar gestational age in the unit was about 0.8%. Therefore, the procedure-related fetal loss rate was estimated to be at the maximum of 0.74%.Conclusions In experienced hands, first trimester transabdominal CVS is an accurate and safe invasive prenatal diagnostic procedure. It should be one of the treatment options available to pregnant women who require prenatal genetic diagnosis.

    Full Text Available Aim. Large food bits can get stuck in the esophagus and must be removed by endoscopy. In some cases, this can be difficult or unsafe. We describe a new and safe treatment for such patients. Materials and Methods. 100 consecutive patients were referred to Akershus University Hospital with impacted food in the esophagus. In 36 patients (36%, the food passed spontaneously. In 59 (92% of the remaining 64 patients, the food was removed by endoscopic intervention. In the last five patients, endoscopic removal was judged difficult or unsafe. These patients received the new treatment: one capsule Creon 10000 IU dissolved in 30 mL of Coca-Cola administered by a nasooesophageal tube four times daily for 2-3 days. Results. Of the 59 patients treated with endoscopic procedure, complications occurred in four (7%: three bleedings and one perforation of the esophagus. In five patients treated with Coca-Cola and Creon, the food had either passed or was soft after 2-3 days and could easily be removed. Conclusion. The treatment of choice of impacted food in the esophagus is endoscopic removal. In cases where this is difficult, we recommend treatment with Coca-Cola and Creon for 2-3 days before complications occur.

    The prevalence of childhood obesity is increasing worldwide. Studies in adult populations show that retinal microvascular changes are associated with obesity and components of the metabolic syndrome. In our study we have assessed the effect of body mass index (BMI), metabolic parameters, and adiposity on the retinal microvasculature in children. Fifty-four consecutive children with biopsy-proven NAFLD were enrolled in this study. Anthropometric and laboratory parameters were obtained using standardized protocols. Retinal caliber was quantified from digital retinal images using well-known computer-based programs. Twenty-four-hour ambulatory blood pressure monitoring was measured using a standard protocol. In our population, the prevalence of retinopathy was of 53 % (13 males). The 29 patients with retinopathy (mean age 10.91 ± 3.10) showed significantly higher values of triglycerides (mg/day) (105.57 vs. 90.20, p = 0.04), basal insulin (mUI/ml) (17.20 vs. 12.97, p = 0.02), and HOMA-IR (3.37 vs. 2.76, p = 0.04). The patients with a HOMA-IR >2.5 (OR = 3.34, p = 0.02; 95 % IC, 1.07-10.39), and systolic non-dipping (OR 4.16, p = 0.028, 95 % IC, 1.11-13.67), have an increased risk of retinopathy. Moreover, the study of correlation between all stages of liver biopsy (CRN criteria) and the grade of retinopathy showed a positive correlation with fibrosis (r = 0.31) and an NAS score (r = 0.28). We found an association between metabolic parameters and nocturnal blood pressure on the retinal microvasculature among the obese children with NAFLD. Furthermore, for the first time, we report the positive relationship between hepatic fibrosis in pediatric NAFLD patients and the degree of retinopathy signs.

    Full Text Available Hypereosinophilic syndrome represents a heterogeneous group of disorders with the common feature of prolonged eosinophilia of unknown cause and organ system dysfunction including the pulmonary system. Hypereosinophilic syndrome, with and without pulmonary involvement, in association with pregnancy is very rare, and to the best of our knowledge only one case of hypereosinophilic syndrome with pulmonary involvement during pregnancy has been previously reported in the medical literature. We describe a case of a patient with previously symptomatic hypereosinophilic syndrome with pulmonary involvement who experienced exacerbations of her disease during two consecutive pregnancies. To the best of our knowledge this is the first report which demonstrates a worsening effect of pregnancy on both eosinophil count and end organ involvement in a patient with previous diagnosis of hypereosinophilic syndrome.

    Diffuse anterior retinoblastoma is an exquisitely rare variant of retinoblastoma in which the tumor resides in the anterior segment of the eye, without apparent retinal involvement. Previously published cases have been managed with enucleation. We describe globe salvage and visual preservation in 3 consecutive cases using chemotherapy and radiotherapy. Retrospective case series. Three children with diffuse anterior retinoblastoma. Plaque radiotherapy plus intravenous chemotherapy. Globe and vision preservation. The mean patient age at presentation elsewhere was 5.7 years (median, 7; range, 3-7 years). There were 2 white female patients and 1 African American male patient. The initial observation by parents/caregiver was reduced vision (n = 1), red eye (n = 1), or cloudy eye (n = 1), and the initial finding by physician was iris tumor (n = 2) or hyphema (n = 1). Referring diagnosis was iris melanoma (n = 1), infectious endotheliitis (n = 1), and possible tumor (nonspecified) (n = 1). At our evaluation, visual acuity was 20/50 to 20/60 (n = 2) and fix no follow (n = 1). In all cases, the opposite eye was normal. Mean intraocular pressure was 20 mm Hg (median, 16; range, 15-30 mmHg). Our examination revealed solid iris tumor (n = 3), ciliary body involvement (n = 2), and anterior chamber seeding (n = 3). In no case was there choroidal or retinal tumor, vitreous seed or subretinal seed, or extrascleral extension. Clear corneal fine-needle aspiration biopsy confirmed the diagnosis as retinoblastoma in each case. Treatment included plaque radiotherapy (n = 3) plus additional systemic chemotherapy (n = 2). At mean follow-up of 35 months (median, 34; range, 20-51 months), there has been no recurrence, extrascleral extension, enucleation, metastasis, or death. In all 3 cases, cataract surgery was necessary at a mean interval of 16 months after complete and stable regression of retinoblastoma. The rare diffuse anterior form of retinoblastoma can be managed with globe

    Using the internal mammary vessels as recipient vessels in free-flap autologous breast reconstruction has become a common practice. However, these vessels are typically accessed by removing a costochondral segment. The purpose of this study was to describe the authors' rib-sparing technique for accessing the internal mammary vessels that is efficient and reliable and limits chest wall morbidity. The authors analyzed 100 consecutive free-tissue transfers for breast reconstruction in which the internal mammary vessels were accessed using a rib-sparing technique. The data were obtained from a prospectively maintained database and medical records. Of the 100 free-flap reconstructions, 47 used deep inferior epigastric perforator flaps, 45 used muscle-sparing transverse rectus abdominis myocutaneous flaps, six used superficial inferior epigastric artery flaps, and two used superior gluteal artery perforator flaps. No rib cartilage was removed in 66, but a segment of rib cartilage was removed in 34 procedures to optimize the exposure and facilitate anastomosis. After the initial learning curve, however, the internal mammary vessels were used in approximately 90 percent of cases without removal of any rib cartilage. The third intercostal space was used to access the internal mammary vessels two-thirds of the time, and the second intercostal space was used one-third of the time. There were no incidences of complications or morbidity associated with the rib-sparing approach to internal mammary vessel harvest. For most patients, the rib-sparing technique is an efficient and safe approach for exposing the internal mammary vasculature for microvascular breast reconstruction while minimizing chest wall morbidity.

    Acute Respiratory Infections (ARIs) are a major health problem, especially in young children and the elderly. Insights into the seasonality of respiratory viruses can help us understand when the burden on society is highest and which age groups are most vulnerable. We monitored six respiratory viruses during five consecutive seasons (2011-2016) in Belgium. Patient specimens (n=22876), tested for one or more of the following respiratory viruses, were included in this analysis: Influenza viruses (IAV & IBV), Human respiratory syncytial virus (hRSV), Human metapneumovirus (hMPV), Adenovirus (ADV) and Human parainfluenza virus (hPIV). Data were analysed for four age categories: <6y, 6-17y, 18-64y and ≥65y. Children <6y had the highest infection rates (39% positive vs. 20% positive adults) and the highest frequency of co-infections. hRSV (28%) and IAV (32%) caused the most common respiratory viral infections and followed, like hMPV, a seasonal pattern with winter peaks. hRSV followed an annual pattern with two peaks: first in young children and ±7 weeks later in elderly. This phenomenon has not been described in literature so far. hPIV and ADV occurred throughout the year with higher rates in winter. Children <6y are most vulnerable for respiratory viral infections and have a higher risk for co-infections. hRSV and IAV are the most common respiratory infections with peaks during the winter season in Belgium.

    Full Text Available The aim of this study was to document vascular complications that occurred fol-lowing cadaveric and living donor kidney transplants in order to assess the overall incidence of these complications at our center as well as to identify possible risk factors. In a retrospective cohort study, 1500 consecutive renal transplant recipients who received a living or cadaveric donor kidney between December 1988 and July 2006 were evaluated. The study was performed at the Nemazee Hospital, Shiraz, Iran. The assessment of the anatomy and number of renal arteries as well as the incidence of vascular complications was made by color doppler ultrasonography, angiography, and/or surgical exploration. Clinically apparent vascular complications were seen in 8.86% of all study patients (n = 133 with the most frequent being hemorrhage (n = 91; 6.1% followed by allo-graft renal artery stenosis (n = 26; 1.7%, renal artery thrombosis (n = 9; 0.6%, and renal vein thrombosis (n = 7; 0.5%. Vascular complications were more frequent in recipients of cadaveric organs than recipients of allografts from living donors (12.5% vs. 7.97%; P= 0.017. The occurrence of vascular complications was significantly more frequent among recipients of renal allografts with multiple arteries when compared with recipients of kidneys with single artery (12.3% vs. 8.2%; P= 0.033. The same was true to venous complications as well (25.4% vs. 8.2%; P< 0.001. Our study shows that vascular complications were more frequent in allografts with multiple renal blood vessels. Also, the complications were much less frequent in recipients of living donor transplants.

    We noted a large amount of intravenous gas during balloon kyphoplasty on CT imaging. Formal assessment to understand the extent, possible causes and implications was undertaken. Ten consecutive cases of balloon kyphoplasty were performed under general anaesthesia in the prone position, on a single vertebral level using a two-step technique under combined fluoroscopic and CT guidance. CT of the affected vertebra was performed before, after, and intermittently during the procedure. In 2 cases delayed CT was carried out in the supine position. Gas was seen on CT imaging, but not on conventional fluoroscopy. The gas is most likely to be air introduced during the procedure and was seen in the epidural and paravertebral venous plexus, posterior intercostal veins, renal veins, IVC and azygos vein. The average measured volume of gas seen on the post-procedure CT imaging was 1.07 mL, range 0.16-3.97 mL. There was no correlation of the measured amount of gas to the procedure duration or location, the use of a curette or the injected cement volume. Delayed CT in the supine position no longer showed air in the local venous system. Balloon kyphoplasty is associated with the fluoroscopically invisible introduction of air into the vertebral and paravertebral veins and deep systemic veins and is likely to be much more extensive than identified on CT imaging. There is potential for serious air embolism in kyphoplasty and if there is a sudden deterioration in patient condition during the procedure the possibility of this complication needs to be considered.

    OBJECTIVE: The social vulnerability that is associated with food allergy (FA) might predispose children with FA to bullying and harassment. This study sought to quantify the extent, methods, and correlates of bullying in a cohort of food-allergic children. METHODS: Patient and parent (83.6% mothers) pairs were consecutively recruited during allergy clinic visits to independently answer questionnaires. Bullying due to FA or for any cause, quality of life (QoL), and distress in both the child and parent were evaluated via questionnaires. RESULTS: Of 251 families who completed the surveys, 45.4% of the children and 36.3% of their parents indicated that the child had been bullied or harassed for any reason, and 31.5% of the children and 24.7% of the parents reported bullying specifically due to FA, frequently including threats with foods, primarily by classmates. Bullying was significantly associated with decreased QoL and increased distress in parents and children, independent of the reported severity of the allergy. A greater frequency of bullying was related to poorer QoL. Parents knew about the child-reported bullying in only 52.1% of the cases. Parental knowledge of bullying was associated with better QoL and less distress in the bullied children. CONCLUSIONS: Bullying is common in food-allergic children. It is associated with lower QoL and distress in children and their parents. Half of the bullying cases remain unknown to parents. When parents are aware of the bullying, the child’s QoL is better. It is important to proactively identify and address cases in this population. PMID:23266926

    To determine if the rate of major discrepancies between resident preliminary reports and faculty final reports increases during the final hours of consecutive 12-hour overnight call shifts. Institutional review board exemption status was obtained for this study. All overnight radiology reports interpreted by residents on-call between January 2010 and June 2010 were reviewed by board-certified faculty and categorized as major discrepancies if they contained a change in interpretation with the potential to impact patient management or outcome. Initial determination of a major discrepancy was at the discretion of individual faculty radiologists based on this general definition. Studies categorized as major discrepancies were secondarily reviewed by the residency program director (M.H.S.) to ensure consistent application of the major discrepancy designation. Multiple variables associated with each report were collected and analyzed, including the time of preliminary interpretation, time into shift study was interpreted, volume of studies interpreted during each shift, day of the week, patient location (inpatient or emergency department), block of shift (2-hour blocks for 12-hour shifts), imaging modality, patient age and gender, resident identification, and faculty identification. Univariate risk factor analysis was performed to determine the optimal data format of each variable (ie, continuous versus categorical). A multivariate logistic regression model was then constructed to account for confounding between variables and identify independent risk factors for major discrepancies. We analyzed 8062 preliminary resident reports with 79 major discrepancies (1.0%). There was a statistically significant increase in major discrepancy rate during the final 2 hours of consecutive 12-hour call shifts. Multivariate analysis confirmed that interpretation during the last 2 hours of 12-hour call shifts (odds ratio (OR) 1.94, 95% confidence interval (CI) 1.18-3.21), cross

    The results of kidney transplantation have improved significantly in the last decade with patient and graft survival rates that range from 92% to 95%. We analyzed the clinical results in the last 100 consecutive patients with a follow-up of 6-42 months at our institution. We also made a general evaluation of the patients before surgery as candidates for transplantation and divided them into 3 groups (good, moderate, and poor). We had 8 living donors and 92 cadaveric kidney transplantation cases. Principal cause of donor death was cerebrovascular disease accounting for 64%. Mean age of recipients was 55.1 ± 12.9 years with a total of 65 males. Currently there are 96 functioning allografts. During this 3-year period, 2 patients suffered graft loss and 2 patients died with a functioning allograft. We studied whether there were statistically significant differences in renal function (Modification of Diet in Renal Disease Study Equation [MDRD]) at 12 months and at last visit with respect to the evaluation of recipient as cand
