    Full Text Available It is widely acknowledged that new regimens are urgently needed for the treatment of tuberculosis. The primary endpoint in the Phase III trials is a composite outcome of failure at the end of treatment or relapse after stopping treatment. Such trials are usually both long and expensive. Valid surrogate endpoints measured during or at the end of treatment could dramatically reduce both the time and cost of assessing the effectiveness of new regimens. The objective of this study was to evaluate sputum culture results on solid media during treatment as surrogate endpoints for poor outcome. Data were obtained from twelve randomised controlled trials conducted by the British Medical Research Council in the 1970s and 80s in East Africa and East Asia, consisting of 6974 participants and 49 different treatment regimens. The month two culture result was shown to be a poor surrogate in East Africa but a good surrogate in Hong Kong. In contrast, the month three culture was a good surrogate in trials conducted in East Africa but not in Hong Kong. As well as differences in location, ethnicity and probable strain of Mycobacteria tuberculosis, Hong Kong trials more often evaluated regimens with rifampicin throughout and intermittent regimens, and patients in East African trials more often presented with extensive cavitation and were slower to convert to culture negative during treatment. An endpoint that is a summary measure of the longitudinal profile of culture results over time or that is able to detect the presence of M. tuberculosis later in treatment is more likely to be a better endpoint for a phase II trial than a culture result at a single time point and may prove to be an acceptable surrogate. More data are needed before any endpoint can be used as a surrogate in a confirmatory phase III trial.

    Full Text Available ABSTRACT OBJECTIVE: To clinically and radiologically evaluate the results from videoarthroscopic treatment using metal anchors in patients with recurrent shoulder dislocation and its complications. METHODS: This was a retrospective study on 47 patients (47 shoulders operated by the shoulder group of the orthopedic hospital between February 2010 and February 2012. A questionnaire, interview and physical and radiographic examinations were used, with the classification of Samilson and Pietro. The mean postoperative follow-up was 33 months (range 12-47 months. The statistical analysis consisted of using Fisher's exact test through the IBM SPSS 22 statistical software. The significance level used was 5%. RESULTS: Recurrence was observed in nine cases. The patients were, on average, 26.5 years old at the first episode, and 19.1% were aged 20 years or under. Among these, 55.6% presented recurrence. In relation to age at the time of the surgical procedure, the average age was 27 years, and 12.8% were aged 20 years or under. Nineteen patients presented prominent anchors and, of these, 21% manifested arthrosis. CONCLUSION: There was a statistically identified correlation between the recurrence rate and age less than or equal to 20 years at the times of first dislocation and the surgical procedure. Further studies should be conducted in order to compare the use of absorbable anchors, which despite higher cost, may provide lower risk of developing glenohumeral arthrosis in some cases.

    NORM is the acronym used to refer to naturally occurring radioactive materials. Besides being objects of study and monitoring such materials can be used as raw material or as by-products or waste of industrial activities. Oil and gas, mining and water treatment are examples of facilities that can handle NORM. In such cases, their concentration at significant levels from the perspective of environmental and occupational radiation protection may occur. This study aims to evaluate the presence of the natural radioactive 238 U and 232 Th series in the treatment of city water elements Pocos de Caldas - MG (water, materials and waste). The study can serve as an indication of the necessity of a more detailed review in the locally and in the country on this radiological issue. (author)

    Purpose: to evaluate the delayed toxicity of two patterns of adjuvant radiotherapy including a breast irradiation, at the dose of 48 Gy in 20 seances and five weeks or 57.60 Gy in 24 seances and six weeks in case of majored factors of local recurrence risk. The secondary objective were the auto evaluation by the patient of the esthetic result and the influence of this last one on the quality of life. Conclusion: the delayed toxicity was dominated by the fibrosis low to moderated one, without any significant difference between the doses of 48 Gy and 57.60 Gy. The esthetic result evaluated by the patient, globally good, seemed however, damaged with the last pattern. A bad esthetic result, without affected the global quality of life was associated to more specific breast symptoms and damaged the perception of the body image. (N.C.)

    The results of EDTA therapy were studied in 37 workers of a battery factory consisting of males with varying degrees of occupational lead poisoning (low exposure: 10 subjects, blood lead levels (PbB) lower than 400 micrograms/l with slight alterations in heme biosynthesis; beyond limit of effect: 5 subjects, PbB > 400 micrograms/l; slight intoxication: 19 subjects, with marked alterations in heme synthesis and preclinical signs of intoxication; average degree of intoxication: 3 subjects with clinical signs of intoxication. Clinical symptoms and the following parameters were investigated: blood lead (PbB), delta-aminolevulinic acid dehydratase in erythrocytes (ALA-D), zinc protoporphyrin (PP) in erythrocytes and delta-aminolevulinic acid (ALA) in 24-hour urine before and after EDTA chelating therapy. Simultaneous measurement of ALA-D and PP showed high diagnostic sensitivity in detecting lead poisoning in occupationally exposed subjects. In view of the high interindividual variability of the results, these indices did not, however, permit a useful differentiation to be made of the different degrees of intoxication at individual level, even though a good correlation was observed between PbB and porphyrin metabolism indices. From the alterations observed in ALA-D and PP values it was not possible to establish an association between degree of alteration and types of clinical symptoms in the different intoxication studies. At the end of EDTA treatment, a clinical improvement was observed in all cases studied but only in 5 cases was a reduction in PbB observed, to levels below 1.20 mol/l, which is accepted as a permissible limit for the general population; in 17 cases PbB remained at levels above the critical value for occupational lead poisoning (400 micrograms/l), although there was a decrease after treatment. The improvement observed in the indices of porphyrin metabolism at the end of treatment was only slight: significant variations were measured only for PbB. After

    Full Text Available Background:Chronic neglected dislocation of the shoulder joint can be defined as a neglected dislocation for more than a 3 week period.However, it has been shown that the negligence could range from a 24 hour period to 6 months1. Depending on age,signs, symptoms,etiology and types of dislocation, conservative treatment or surgical intervention could be considered.Methods: In this study, 16 patients (13 were male and 3 were female were treated with chronic shoulder dislocations, 3 of which had bilateral dislocations. The age of this group ranged from 13-65 years with a mean age of 34 years. These patients were treated by closed or open reduction, either anterior, posterior or both approaches. Of 19 dislocations, 6 were anterior unilateral, 7 posterior unilateral, 1 anterior bilateral and 2 posterior bilateral dislocations. The mean period between dislocations and treatments was 3 months (from 4 weeks to 11 months,And the mean follow up period was 40 months (from 21 months to 5 years.Results: This study has shown that treatment varies according to pathology. In  this study the mean size of head defects was 35% and the extent of severity determined the approach. Findings at the last follow up were assessed according to Rowe and Zarins score and of the 19 shoulders assessed, 9 showed good and 10 showed excellent results. There was no recurrence of the dislocation in any patient.Conclusion:In some selected instances, open reduction of a chronic locked neglected shoulder dislocation of a 6 months period or more in young patients is recommended.This method is, however, contraindicated in elderly patients; in such cases a shoulder prosthesis is indicated.

    Overweight and obesity are ranked in the fifth place among the risk factors responsible for the greatest number of deaths in the world. To assess the effects of treatment of patients with morbid obesity using endoscopic intragastric balloon (IGB) implantation. Two hundred and seventy-two patients with obesity were treated using endoscopic intragastric balloon implantation. Upon analysis of the inclusion and exclusion criteria, the study covered a group of 63 patients with morbid obesity. The patients were implanted with the LexBal balloon. Reduction of excess body mass, changes to BMI values and ailments and complications divided into mild and severe were assessed. Before intragastric balloon treatment, the average body mass index (BMI) value was 58.3 ±10.5 kg/m 2 , whereas after 6 months of treatment it decreased to 49.5 ±8.7 kg/m 2 . The patients with postoperative BMI equal to or greater than 50.0 kg/m 2 reported nausea (69.7%), vomiting (51.5%), flatulence (45.5%), upper abdominal pain (36.4%) and general discomfort (424%) more frequently. Dehydration (9.1%) was also more frequent in this group, whereas frequency of occurrence of such ailments and complications as heartburn (23.3%) and oesophageal candidiasis (10.0%) was higher in the patients with postoperative BMI below 50.0 kg/m 2 . Endoscopic intragastric balloon implantation is an effective and safe method of excess body mass reduction in patients with morbid obesity before a planned bariatric surgical procedure. Pre-operative excess body mass and BMI value and post-operative excess weight loss in patients with morbid obesity have no impact on frequency of occurrence of ailments and complications in IGB treatment.

    The vasovagal syncope is a reflex reaction to various stimuli leading to the marked hypotension with or without bradycardia with loss of consciousness and fall of postural muscle tone. The vast majority of the patients recover spontaneously but if the syncope occurs frequently and causes injury of the patients body it worsens the quality of life and needs appropriate treatment. The injuries requiring hospitalization occur approximately in 10% of the patients with vasovagal syncope. The aim of the therapy of affected patients is to diminish the syncope prevalence, to brake the neurocardiogenic reaction on an early stage or to prolong the duration of the presyncope phase to enable the patient prevention of the injury. The lack of clear diagnostic criteria and difficulties with estimation the efficacy of any particular therapeutic intervention in many clinical studies of different authors, inclusion to the studies patients with different clinical presentation stages of the disease contribute to different conclusions, which automatic use in the clinical practice is inappropriate. There is an urgent need to clear the methodological discrepancies and to conduct good planed, large, randomized, multicentre studies to assess the efficacy of different therapeutic methods in the treatment of vasovagal syncope.

    Full Text Available Introduction: Diaphragmatic hernia could be caused by congenital disorders, blunt trauma or penetrating injuries. The diagnosis of traumatic diaphragmatic hernia is normally neglected during the first presentation leading to late complications and considerably increased mortality and morbidity among the patients. Materials and Methods: In this retrospective, descriptive study, we reviewed the medical records of patients presented with traumatic diaphragmatic hernia who had undergone surgical operations between 1982-2015 in Ghaem Hospital and Omid Hospital affiliated to Mashhad University of Medical Sciences, Iran. The studied variables included age, gender, clinical symptoms, location of hernia, involved organs, type of imaging modalities, surgical techniques, length of hospital stay, mortality rate and surgical complications. Results: In this study, 38 patients were diagnosed with traumatic diaphragmatic hernia consisting of 28 men and 10 women. In total, 79% and 21% of the patients suffered from penetrating trauma and blunt trauma, respectively. In addition, left-sided, right-sided and bilateral hernias were present in 33%, 4% and 1% of the patients, respectively. The most frequently herniated organ was the stomach, and the most common clinical symptoms were abdominal pain (84% and dyspnea (53%. Initially, chest radiographs were performed on all the patients, and thoracotomy was performed to repair diaphragmatic tears in all the cases (100%. In this study, 3 patients had previously undergone Hartmann’s operation for gangrenous herniated colon, and devolvulation of gastric volvulus had also been performed on 3 patients. The main post-operative complications were reported to be pneumonia and respiratory insufficiency (2 cases, and the mean length of hospital stay was 6 days (5-8 days which was longer (1-2 months in patients with gangrenous bowel (3 patients. Furthermore, no mortality was reported during the course of hospitalization in these

    Full Text Available OBJECTIVES: To evaluate the results from arthroscopic surgical treatment of rotator cuff injuries in patients aged 65 years and over.METHODS: Between 1998 and 2009, 168 patients underwent operations. Five cases were excluded. The remaining 163 patients were stratified according to their age group: 65-69 years (49.1%, 70-74 (26.4% and 75 years and over (24.5%. Their mean age was 71 years (range: 65-83. There were 63 male patients (38.7%. The mean length of time with pain, from the onset of symptoms to the surgery, was 23 months (range: 2 days to 240 months. Sixty-two patients (38% reported histories of trauma and 26 (16% reported that their pain worsened through exertion.RESULTS: From the UCLA criteria, 80.4% of the results were excellent, 16% good, 1.8% fair and 1.8% poor. Complications occurred in 11%. The final clinical result did not show any correlation with age progression, injury size or tendons affected. However, there was a significant association (p < 0.001 between the presence of trauma and larger injuries. The length of time between the onset of symptoms and the surgical procedure had a significant relationship (p < 0.027 with the postoperative results: the longer this time was, the worse the results were.CONCLUSION: Arthroscopic treatment of rotator cuff injuries in patients aged 65 years and over presented excellent and good results in 96.4% of the cases, according to the UCLA assessment, with a low complication rate. Advanced age did not show any influence on the postoperative clinical evolution, but the earlier the surgical treatment was instituted, the better the results were.

    To improve the surgical rate and the quality of life (QOL) for patients with advanced low rectal carcinoma, we investigated whether preoperative treatments (irradiation and hyperthermia and 5-fluorouracil (5-FU) suppository, irradiation and hyperthermia, irradiation and 5-FU suppository, irradiation alone and 5-FU suppository alone) were useful. The tumor shrinkage rate after preoperative treatments was highest in the irradiation, hyperthermia and 5-FU suppository group. Pathologically complete regression was observed in the 2 of 18 cases (12%). According to our criteria of histological changes, the irradiation, hyperthermia and 5-FU suppository group showed the greatest effectiveness. The 4 year postoperative survival rate and the 4 year local recurrence rate were 100% and 8% in the irradiation, hyperthermia and 5-FU suppository group and the data suggest that these results were the best of the 5 treatments. After the carcinoma was shrunk after irradiation, hyperthermia and 5-FU suppository, the patients could receive curatively a sphincter-saving operation (super-low anterior resection and transanal rectal resection). The fecal continence of 7 patients after sphincter-saving operations was increased as good by manometric study, defecography and clinical evaluation. In conclusion, our data suggest that the preoperative combined treatment of irradiation, hyperthermia and 5-FU suppository prevents local recurrence and increases the possibility of a sphincter-saving operation for advanced rectal carcinoma.

    Total body irradiation (TBI) is a well established part of the conditioning regimen prior to bone marrow transplantation (BMT). Numerous different techniques are used and every center elaborates own solutions. The aim of our study to present the method of TBI developed in our department, and to discuss the results of treatment with respect of early and late toxicity. Between 11.2000 and 08.2004, 23 patients were with fractionated TBI at the Department of Radiotherapy of the M. Sklodowska-Curie Memorial Cancer Center and Institute of Oncology in Warsaw (MSCMCC). Conditioning chemotherapy and BMT were performed in different hematological departments. All patients were irradiated with a total midline dose of 12 Gy in 6 fractions over 3 consecutive days. Doses to the lung did not exceed 11 Gy. The TBI method used in our department was evaluated over a few years. The following modifications have been introduced to the previously applied technique: change of photon energy 6 MV to 15 MV; increase of lung dose from 9 Gy to 11 Gy; the use of an individual bolus as a lung compensator in lateral fields; more frequent boost irradiation of the mediastinum and legs with small fields; calculations of Monitor Units based on dosimetric data. Boost irradiation of chest wall with electrons been abandoned. Median follow up was 12 months. Up till now, 17/23 patients are alive, of these 16 with no relapse. Immediate toxicity was low. Early complications were observed during the first 6 months after BMT in 11 patients. In the case of 4 patients these complications were fatal. Late complications were observed in 10 patients, including chronic GVHD and hormone disturbance. Only one patient had developed the first symptoms of cataract. In one case Lhermitte's syndrome was observed. One patient died due to liver insufficiency. The results of treatment and the complications rates in patients treated with TBI at our department are consistent with those published in literature. We conclude that

    The U.S. Department of Energy (DOE) is responsible for the final disposition of legacy spent nuclear fuel (SNF). As a response, DOE's National Spent Nuclear Fuel Program (NSNFP) has been given the responsibility for the disposition of DOE-owned SNF. Many treatment technologies have been identified to treat some forms of SNF so that the resulting treated product is acceptable by the disposition site. One of these promising treatment processes is the electrometallurgical treatment (EMT) currently in development; a second is an Acid Wash Decladding process. The NSNFP has been tasked with identifying possible strategies for the deployment of these treatment processes in the event that a treatment path is deemed necessary. To support the siting studies of these strategies, economic evaluations are being performed to identify the least-cost deployment path. This model (tool) was developed to consider the full scope of costs, technical feasibility, process material disposition, and schedule attributes over the life of each deployment alternative. Using standard personal computer (PC) software, the model was developed as a comprehensive technology economic assessment tool using a Life-Cycle Cost (LCC) analysis methodology. Model development was planned as a systematic, iterative process of identifying and bounding the required activities to dispose of SNF. To support the evaluation process, activities are decomposed into lower level, easier to estimate activities. Sensitivity studies can then be performed on these activities, defining cost issues and testing results against the originally stated problem

    To investigate the clinical results of occlusal splint in the treatment of sagittal fracture of mandibular condyle (SFMC) in children. Thirty-nine patients (48 condyles)aged 3-8 years with sagittal fracture of mandibular condyle were included in this study. All the patients were treated by occlusal splint.Slight open occlusion was maintained by occlusal splint for 3-6 months. Clinical and radiological examination was performed six mouths and every year after treatment. Good mandibular function was observed in 39 patients. Maximal mouth opening over 35 mm was achieved at 6 months. But 11 of the 39 patients presented with deviation on mouth opening at 6 months. The radiology showed an complete remodeling in 32 condyles (28 patients) and partial remodeling in 16 condyles (11 patients). Poor remodelling was not observed in any patients. Good clinical results can be obtained by using occlusal splint in the treatment of pediatric sagittal fracture of mandibular condyle.

    An analysis was made on relationship between Notching and functional and radiographic parameters after treatment of acute proximal humeral fractures with reverse total shoulder arthroplasty. A retrospective evaluation was performed on 37 patients with acute proximal humeral fracture treated by reversed shoulder arthroplasty. The mean follow-up was 24 months. Range of motion, intraoperative and postoperative complications were recorded. Nerot's classification was used to evaluate Notching. Patient satisfaction was evaluated with the Constant Score (CS). Statistical analysis was performed to evaluate the relationship between Notching and glenosphere position, or functional outcomes. Mean range of elevation, abduction, external and internal rotation were 106.22°, 104.46°, 46.08° and 40.27°, respectively. Mean CS was 63. Notching was present at 12 months in 29% of patients. Statistical analysis showed significance differences between age and CS, age and notching development, and tilt with notching. No statistical significance differences were found between elevation, abduction, internal and external rotation and CS either with scapular or glenosphere-neck angle. Reverse shoulder arthroplasty is a valuable option for acute humeral fractures in patients with osteoporosis and cuff-tear arthropathy. It leads to early pain relief and shoulder motion. Nevertheless, it is not exempt from complications, and long-term studies are needed to determine the importance of notching. Copyright © 2014 SECOT. Published by Elsevier Espana.

    Purpose : We tried to evaluate the clinical characteristics, the treatment methods, the results of treatments, and the patterns of failure in ovarian dysgerminoma retrospectively. According to the results we would like to suggest the proper management guideline of stage la ovarian dysgerminoma patients who want to maintain fertility. Methods and Materials : Between 1975 and 1990, 34 patients with ovarian dysgerminoma were treated at the Yonsei University Hospital. The case records of these patients have been reviewed for presenting symptoms, treatment methods, local control, and survival following treatment. Excluded from analysis were five patients with mixed ovarian germ cell tumors and gonadoblastomas (46,XY). Treatment results of the twenty nine patients were analysed by each treatment modality. Twenty one patients were treated with surgery and postoperative adjuvant radiotherapy(group 1). The other eight patients were treated with operation alone (group 2). The median age of twenty-nine patients was 23 years with a range of 8 to 39 years. Presenting symptoms were abdominal mass(20), pelvic discomfort or pain(5) et al. Radiotherapy was performed by 10MV LINAC or Co-60 teletherapy unit. The total radiation dose of the whole abdomen was 20-25 Gy/3 weeks, 1-1.5 Gy/fraction with a boost to the whole pelvis 10-15 Gy / 1-2 weeks1.8-2.0 Gy/fraction. Advanced stage disease (stage II or stage III) patients received prophylactic mediastinal and supraclavicular irradiation to a dose of 16-26 Gy. Median duration of follow-up of living patients was 80 months (range : 13-201 months). Results : All of the twenty one patients of group 1 were alive without disease (100%). Among the eight patients who were not treated with radiotherapy (group 2), six patients developed local recurrence. Four patients referred with recurrent disease were treated with salvage radiotherapy. Three of four patients were salvaged and one patient who had recurrent intra-abdominal disease died of

    Because of the very short half-life of factor VII, prophylaxis in factor VII deficiency is considered a difficult endeavor. The clinical efficacy and safety of prophylactic regimens, and indications for their use, were evaluated in factor VII-deficient patients in the Seven Treatment Evaluation Registry. Prophylaxis data (38 courses) were analyzed from 34 patients with severe factor VII deficiency (factor VII (24 courses), four received plasma-derived factor VII, and ten received fresh frozen plasma. Prophylactic schedules clustered into "frequent" courses (three times weekly, n=23) and "infrequent" courses (≤ 2 times weekly, n=15). Excluding courses for menorrhagia, "frequent" and "infrequent" courses produced 18/23 (78%) and 5/12 (41%) "excellent" outcomes, respectively; relative risk, 1.88; 95% confidence interval, 0.93-3.79; P=0.079. Long term prophylaxis lasted from 1 to >10 years. No thrombosis or new inhibitors occurred. In conclusion, a subset of patients with factor VII deficiency needed prophylaxis because of severe bleeding. Recombinant activated factor VII schedules based on "frequent" administrations (three times weekly) and a 90 μg/kg total weekly dose were effective. These data provide a rationale for long-term, safe prophylaxis in factor VII deficiency.

    From March of 1979 through December of 1982, 84 patients with supraglottic carcinoma were seen and evaluated in the Department of Therapeutic Radiology, Seoul National University Hospital. Of these, 68 patients were treated with a curative intent by employing either radiotherapy alone or a combined approach of radiotherapy plus surgery. Sixteen patients refused to complete the treatment program. Seventy-three per cent of patients had T3 and T4 lesions and 63% of patients had lymph node metastasis at the time of diagnosis. Actuarial recurrence-free survival at 3 year was: Stage I-III 62%, Stage III 54%, Stage IV 18%. For T1-2, T3 and T4 lesions, the actuarial recurrence free survival at 3 years were 50%, 34% and 9% respectively. Of 39 patients with treatment failure, 29 patients (78%) had uncontrol or ultimate recurrence at the primary site while 9 patients having lymph node recurrence, 14 patients(21%) had lymph node recurrence, and 5 patients had distant metastasis. It is suggested that planned combined radiotherapy is indicated for advanced but respectable supraglottic carcinoma

    Full Text Available Chronic liver scarring from any cause leads to cirrhosis, portal hypertension, and a progressive decline in renal blood flow and renal function. Extreme renal vasoconstriction characterizes hepatorenal syndrome, a functional and potentially reversible form of acute kidney injury in patients with advanced cirrhosis, but current therapy with systemic vasoconstrictors is ineffective in a substantial proportion of patients and is limited by ischemic adverse events. Serelaxin (recombinant human relaxin-2 is a peptide molecule with anti-fibrotic and vasoprotective properties that binds to relaxin family peptide receptor-1 (RXFP1 and has been shown to increase renal perfusion in healthy human volunteers. We hypothesized that serelaxin could ameliorate renal vasoconstriction and renal dysfunction in patients with cirrhosis and portal hypertension.To establish preclinical proof of concept, we developed two independent rat models of cirrhosis that were characterized by progressive reduction in renal blood flow and glomerular filtration rate and showed evidence of renal endothelial dysfunction. We then set out to further explore and validate our hypothesis in a phase 2 randomized open-label parallel-group study in male and female patients with alcohol-related cirrhosis and portal hypertension. Forty patients were randomized 1:1 to treatment with serelaxin intravenous (i.v. infusion (for 60 min at 80 μg/kg/d and then 60 min at 30 μg/kg/d or terlipressin (single 2-mg i.v. bolus, and the regional hemodynamic effects were quantified by phase contrast magnetic resonance angiography at baseline and after 120 min. The primary endpoint was the change from baseline in total renal artery blood flow. Therapeutic targeting of renal vasoconstriction with serelaxin in the rat models increased kidney perfusion, oxygenation, and function through reduction in renal vascular resistance, reversal of endothelial dysfunction, and increased activation of the AKT

    Full Text Available Regardless the success gained in treatment of acute lymphoblastic leukaemia, several problems still remain to be solved, such as: overcoming primary drug resistance and minimizing the amount of relapses as well as decreasing of chemotherapy toxicity without detriment to the final outcome of the treatment. Development of an optimal chemotherapeutical strategy still remains a hot issue. Objective: to evaluate an efficacy of two modifications of German protocol COALL-92 in treatment of ALL in children in St.-Petersburg. Methods: the retrospective analysis of results of treatment in patients under 18 years old with ALL was performed. The diagnosis was confirmed according to international criteria. The treatment was performed via protocols PECO-92 and COALL-St.-Petersburg-92. Results: 438 initial patients with ALL were treated in St.-Petersburg clinics during the period from 01.01.1993 to 01.01.2007. At the time of analysis the probability of event-free survival (pEFS was 60% in group of PECO-92 protocol and 70% — in COALL group (plog-rank = 0,048, probability of relapse-free survival (рRFS was 65 and 74% (plog-rank = 0,002, probability of overall survival was (pOS 78 and 70%, correspondingly (plog-rank = 0,079. Conclusion: inclusion of protocol treatment in practice of St.-Petersburg hospitals resulted in significant improvement of treatment results in children with ALL. The problem of both versions of COALL protocol is high rate of postremission mortality due to high toxicity of intensive stage if chemotherapy.Key words: children, acute lymphoblastic leukemia, intensive chemotherapy.(Voprosy sovremennoi pediatrii — Current Pediatrics. 2011; 10 (3: 33–42

    The first HTA guidelines for Thailand included a chapter outlining a set of guidelines on how best to report the findings of health economic evaluations, based on a review of best practice and existing guidelines on the presentation of economic evaluation results from around the world. In this second edition of HTA guidelines for Thailand, the recommendations build on the first edition by using a case study to illustrate how the guidelines can be applied in a real research context. The guidelines propose that all reporting include ten key elements: defining the scope of the study, selection of comparator(s), defining the type of economic evaluation, measurement of costs, measurement of clinical effects, handling time in economic evaluation studies, handling uncertainty and sensitivity analysis, presentation of the results, discussion of the results, and disclosure of funding and authors conflict of interest.

    Some types of pneumoconiosis, such as asbestosis, are characterized by marked restrictive functional patterns. Treatment is begun when definite arterial hypoxemia appears, since the inhalation of oxygen clearly lowers pulmonary artery pressure. It is also important that the onset of concomitant airway obstruction is recognized promptly. From the sociomedical standpoint the most significant pneumoconiosis continues to be the miner's anthracosilicosis. The functional pattern of this pneumoconiosis is clearly airway obstruction, and such anthracosilicotic airway obstruction responds like all other forms of airway obstruction to antiobstructive therapy. The fundamentals of this therapy, which is based on the use of bronchodilators, adrenal cortical hormones and antibiotics, are described.

    Management of pancreatic cancer (PC) in elderly patients is unknown; clinical trials exclude patients with comorbidities and those of extreme age. This study evaluated treatment patterns and survival outcomes in elderly PC patients using linked Surveillance, Epidemiology, and End Results (SEER) and Medicare data. Histology codes 8140, 8500, 8010, 8560, 8490, 8000, 8260, 8255, 8261, 8263, 8020, 8050, 8141, 8144, 8210, 8211, or 8262 in Medicare Parts A and B were identified. Data regarding demographic, characteristics, treatments, and vital status between 1998 and 2009 were collected from the SEER. Determinants of treatment receipt and overall survival were examined using logistic regression and Cox proportional hazards models, respectively. A total of 5,975 patients met inclusion. The majority of patients were non-Hispanic whites (85%) and female (55%). Most cases presented with locoregional stage disease (74%); 41% received only chemotherapy, 30% chemotherapy and surgery, 10% surgery alone, 3% radiation, and 16% no cancer-directed therapy. Patients with more advanced cancer, older age, and those residing in areas of poverty were more likely to receive no treatment. Among patients 66-74 years of age with locoregional disease, surgery alone (hazard ratio [HR] = 0.54; 95% confidence interval [CI]: 0.39-0.74) and surgery in combination with chemotherapy (HR = 0.69; 95% CI: 0.53-0.91) showed survival benefit as compared with the no treatment group. Among patients ≥75 years of age with locoregional disease, surgery alone (HR = 2.04; 95% CI: 0.87-4.8) or in combination with chemotherapy (HR = 1.59; 95% CI: 0.87-2.91) was not associated with better survival. Treatment modality and survival differs by age and stage. Low socioeconomic status appears to be a major barrier to the receipt of PC therapy among Medicare patients. Elderly patients with cancer are under-represented on clinical trials and usually have comorbid illnesses. The management of elderly

    Ipilimumab is a newly approved immunotherapeutic agent that has been shown to provide a survival benefit in patients with metastatic melanoma. {sup 18}F-FDG PET/CT has demonstrated very satisfying results in detecting melanoma metastases in general. Using {sup 18}F-FDG PET/CT we monitored patients with metastatic melanoma undergoing ipilimumab therapy during the course of treatment. The aim of our study was to evaluate the role of {sup 18}F-FDG PET/CT performed after two cycles of ipilimumab in predicting the final response to therapy. In 22 patients suffering from unresectable metastatic melanoma, scheduled for ipilimumab treatment PET/CT scanning was performed before the start of treatment (baseline scan), after two cycles of treatment (early response) and at the end of treatment after four cycles (late response). Evaluation of the patient response to treatment on PET was based on the European Organization for Research and Treatment of Cancer 1999 criteria. Progression-free survival (PFS) and overall survival (OS) data are presented. After the end of treatment, 15 patients were characterized as having progressive metabolic disease (PMD) and five as having stable metabolic disease (SMD), and two patients showed a partial metabolic response (PMR). Early PET/CT performed after two ipilimumab cycles predicted treatment response in 13 of the 15 PMD patients, in five of the five SMD patients and in neither of the two PMR patients. Both patients with PMR showed pseudoprogression after the second cycle and were therefore wrongly classified. According to the patients' clinical outcome, patients with late PMD had a median PFS of 3.6 months (mean 5.6 months), while patients with late SMD had a median PFS of 9.8 months (mean 9.0 months). In comparison, patients with early PMD had a median PFS of 2.7 months (mean 5.5 months) and patients with early SMD had a median PFS of 6.3 months (mean 7.5 months). The difference in PFS between the two groups was statistically

    Patients and Methods: This longitudinal study prospectively evaluates quality of life in two groups consisting of 53 neoadjuvant and primarily surgically treated patients with oral cancer, using the quality-of-life core questionnaire (QLQ-C30) and the head and neck cancer module (H and N 35) of the European Organization for Research and Treatment of Cancer (EORTC). Results: Postoperatively both groups showed a marked reduction in quality of life. 1 year later quality of life had equalized between the two groups to such an extent that the quality of life scores had almost reached the preoperative level. Both groups showed specific impairments in the symptom scales. In the neoadjuvant therapy group however, global health and the emotional status were reduced to a greater degree than in the other group. Conclusion: Temporary limitations in quality of life can be expected after tumor treatment of oral cancer as presented here. Neoadjuvant therapy concept is more aggressive and might result in a longer disease-free survival, but the restriction in quality of life is more severe. Primary goal is the eradication of the tumor. Nevertheless preservation or reconstruction of a maximum of function is essential for a high level of quality of life. (orig.) [de

    Full Text Available OBJECTIVE: To evaluate the incidence of consolidation in surgical treatment of fractures of the lateral extremity of the clavicle using the double subcoracoid ligature technique, with nonabsorbable No. 5 thread.METHODS: Between May 1993 and June 2013, the Shoulder and Elbow Group of our service surgically treated 116 patients (116 shoulders with fractures of the lateral extremity of the clavicle. Among these, we were able to reassess 65 cases. The surgical technique used consisted of double subcoracoid ligature with two nonabsorbable threads. In two patients classified as type III, we had to combine this technique with use of an interfragmentary screw for fixation of the intra-articular portion of the acromioclavicular joint.RESULTS: We achieved fracture consolidation in 90%. Fourteen cases (21% evolved with major complications: four cases of pseudarthrosis, five of adhesive capsulitis, two of delayed consolidation and three of loss of reduction. Two cases (3% evolved with minor complications of skin granuloma.CONCLUSION: The double ligature technique for fractures of the lateral extremity of the clavicle promotes the stabilization needed for consolidation to take place, without the need for synthesis using metal components. It avoids reoperation for the synthesis material to be removed. Moreover, it is a low-cost procedure with good reproducibility and preservation of the acromioclavicular joint.

    Full Text Available We consider implications of the Regional Earthquake Likelihood Models (RELM test results with regard to earthquake forecasting. Prospective forecasts were solicited for M≥4.95 earthquakes in California during the period 2006–2010. During this period 31 earthquakes occurred in the test region with M≥4.95. We consider five forecasts that were submitted for the test. We compare the forecasts utilizing forecast verification methodology developed in the atmospheric sciences, specifically for tornadoes. We utilize a “skill score” based on the forecast scores λfi of occurrence of the test earthquakes. A perfect forecast would have λfi=1, and a random (no skill forecast would have λfi=2.86×10-3. The best forecasts (largest value of λfi for the 31 earthquakes had values of λfi=1.24×10-1 to λfi=5.49×10-3. The best mean forecast for all earthquakes was λ̅f=2.84×10-2. The best forecasts are about an order of magnitude better than random forecasts. We discuss the earthquakes, the forecasts, and alternative methods of evaluation of the performance of RELM forecasts. We also discuss the relative merits of alarm-based versus probability-based forecasts.

    The authors here analyse the emission of greenhouse gases (GHG) resulting from the various treatment of municipal solid waste found in the town of Yaounde. Four management systems have been taken as the basis for analyses. System 1 is the traditional collection and landfill disposal, while in system 2 the hiogas produced in the landfill is recuperated to produce electricity. In systems 3 and 4, in addition to the collection, we have introduced a centralised composting or biogas plant before the landfilling disposal of refuse. A Life Cycle Inventory (LCI) of the four systems was made; this enable us to quantify the flux of matter and of energy, consumed or produced by the systems. Following this, only the greenhouse effect was taken into account to evaluate the ecological consequences of the MSW management systems. The method used to evaluate this impact takes into consideration on the one hand, GHG emissions or avoided emission following the substitution of fuel with methane recovered from landfills or produced in the digesters, and on the other hand, sequestrated carbon in the soil following the regular deposit of compost. Landfilling without recuperation of methane is the most emitting solution for greenhouse gas: it leads to the emission of 1.7 ton of carbon dioxide equivalent (tCO2E) per ton of household waste. Composting and methanisation allow one to have a comparable level of emission reduction, either respectively 1.8 and 2 tCO2E/t of MSW. In order to reduce the emission of GHG in the waste management systems, it is advisable to avoid first of all the emissions of methane coming from the landfills. System 2 seems to be a solution that would reduce the emissions of GHG at low cost (2.2 to 4 $/tCO2E). System 2 is calculated as the most effective at the environmental and economic level in the context of Yaounde. Therefore traditional collection, landfill disposal and biogas recuperation to produce electricity is preferable in moist tropical climates.

  17. Gynecomastia: physiopathology, evaluation and treatment

    Directory of Open Access Journals (Sweden)

    Alfredo Carlos Simões Dornellas de Barros

    Full Text Available Gynecomastia (GM is characterized by enlargement of the male breast, caused by glandular proliferation and fat deposition. GM is common and occurs in adolescents, adults and in old age. The aim of this review is to discuss the pathophysiology, etiology, evaluation and therapy of GM. A hormonal imbalance between estrogens and androgens is the key hallmark of GM generation. The etiology of GM is attributable to physiological factors, endocrine tumors or dysfunctions, non-endocrine diseases, drug use or idiopathic causes. Clinical evaluation must address diagnostic confirmation, search for an etiological factor and classify GM into severity grades to guide the treatment. A proposal for tailored therapy is presented. Weight loss, reassurance, pharmacotherapy with tamoxifen and surgical correction are the therapeutic options. For long-standing GM, the best results are generally achieved through surgery, combining liposuction and mammary adenectomy.

    The objective of the present study was to estimate the effectiveness of the new therapeutic modalities for the spa and health resort-based treatment of metabolic syndrome based on the results of the long-term follow-up observations. A total of 100 patients presenting with metabolic syndrome were recruited for the participation in the study. All of them underwent a shortened course of mineral water intake in the combination with the use of the herbal medicinal products. The results of the study give evidence of the more favorable changes in the clinical and instrumental characteristics of the patients with metabolic syndrome treated with the use of the proposed approach in comparison the patients treated by the conventional methods. Moreover, the beneficial effects of the proposed approach persisted during a longer period. The basal treatment given to our patients was supplemented by dietary therapy, therapeutic physical exercise, narzan baths, intake of mineral water having a temperature of 35-37 °С in conjunction with sulphate mineral water (narzan) cooled to 13-15 °С, and a phytococktail. The results of the long-term observations confirmed the enhanced effectiveness of the spa and health resort-based treatment of metabolic syndrome including the therapeutic courses with the intake of cooled narzan mineral water in the combination with phytococktails. This therapeutic modality increased the duration of the favorable changes of various parameters that characterize metabolic syndrome. Specifically, they persisted during 5-6 months after the application of the standard methods, were still apparent within 6-7 months after the two-week course of the treatment with cold narzan and phytococktails, and during 8-9 months when the duration of the treatment course was extended up to 3 weeks.

    Validity and reliability of the Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ) had already been verified as the patients' self-rating assessment of low back pain and lumbar spinal disease and, the present study demonstrated the responsiveness of this measure. 192 subjects who were determined by medical instructors of the Japanese Society for Spine Surgery and Related Research were analyzed. They had completed a series of treatment and both surveys before and after the treatment. Authors investigated rates of concordance between assessment by physicians and subjective assessment by patients. The mean, standard deviation, minimum, 25th percentile, median, 75th percentile and maximum values for pre-treatment, post-treatment, and acquired points were calculated, and then, we also investigated the trend between subjective assessment by patients and mean acquired points for each JOABPEQ domain and substantial clinical benefit thresholds for the JOABPEQ. Symptom changes as assessed by physicians did not coincide with those by patients, and acquired points in each JOABPEQ domain were significantly increased with improved self-rating by patients. In addition, patients who rated symptom changes as "slightly improved" showed a mean acquired points of ≥20, and those reporting "improved" showed a 25th percentile points of the acquired points of ≥20 approximately. A significant correlation was noted between the self-rating of patients and acquired points JOABPEQ, suggesting that ≥20 acquired points can be interpreted as substantial clinical benefit thresholds for the JOABPEQ.

    A gold standard for evaluation of aesthetic outcome after breast-conserving therapy (BCT) is still lacking. The BCCT.core software has been developed to assess aesthetic result in a standardised way. We aimed to study how the result of BCCT.core after BCT is associated with quality of life, measured with the BREAST-Q™, a validated questionnaire. Women eligible for BCT were consecutively recruited between February 1st 2008 and January 31st 2012 (n = 653). Photographs of 310 women, taken one year after BCT, were evaluated using the BCCT.core software. The postoperative BCT module of the BREAST-Q™ questionnaire was administered by mail and 348 questionnaires were returned (median 5.5 years after BCT). In all, 216 women had both BCCT.core results and completed BREAST-Q™ questionnaires available. The results from the BCCT.core evaluation were: excellent n = 49 (15.8%); good n = 178 (57.4%); fair n = 73 (23.5%); poor n = 10 (3.2%). The median BREAST-Q™ score for satisfaction with breasts was 66 [interquartile range (IQR) 57-80] and for psychosocial well-being 82 (IQR 61-100). Poor/fair results on BCCT.core were associated with Q-scores below median for both satisfaction with breasts [odds ratio (OR) 3.4 (confidence interval (CI) 1.7-6.8)] as well as for psychosocial well-being [OR 2.2 (CI 1.1-4.2)]. A statistically significant association between BCCT.core results one year after BCT and quality of life ratings using BREAST-Q™ several years later is shown in this study. This implies that the BCCT.core may be valuable in BCT follow-up and used as a standardised instrument in the evaluation of aesthetic results.

    New data developed, collected, and evaluated to further assess the in-pool performance of the neutron absorber material, Boraflex. The data are from new EPRI test programs, utility surveillance programs, and blackness testing at a number of plants. This new data provides a basis for quantifying the gap phenomenon in full length panels of Boraflex in spent fuel racks; the maximum anticipated gap size, frequency of gap occurrence, and axial distribution of gaps. Methods have been developed to assess the reactivity effects of gaps and Boraflex shrinkage. The analyses presented demonstrates that the reactivity effect of gaps is very small, not much larger than the statistical variations inherent in the calculational method. The data and analyses presented serve to close the issue of gap formation and shrinkage in panels of Boraflex and the effect of such gaps and shrinkage on the reactivity of the fuel/rack configuration. Ongoing EPRI programs to assess the long term performance of Boraflex in spent fuel storage racks are described

    To investigate whether uterine artery embolization (UAE) is a cost-effective alternative to hysterectomy for patients with symptomatic uterine fibroids, the authors performed an economic evaluation alongside the multicenter randomized EMMY (EMbolization versus hysterectoMY) trial. Between February 2002 and February 2004, 177 patients were randomized to undergo UAE (n = 88) or hysterectomy (n = 89) and followed up until 24 months after initial treatment allocation. Conditional on the equivalence of clinical outcome, a cost minimization analysis was performed according to the intention to treat principle. Costs included health care costs inside and outside the hospital as well as costs related to absence from work (societal perspective). Cumulative standardized costs were estimated as volumes multiplied with prices. The nonparametric bootstrap method was used to quantify differences in mean (95% confidence interval [CI]) costs between the strategies. In total, 81 patients underwent UAE and 75 underwent hysterectomy. In the UAE group, 19 patients (23%) underwent secondary hysterectomies. The mean total costs per patient in the UAE group were significantly lower than those in the hysterectomy group ($11,626 vs $18,563; mean difference, -$6,936 [-37%], 95% CI: -$9,548, $4,281). The direct medical in-hospital costs were significantly lower in the UAE group: $6,688 vs $8,313 (mean difference, -$1,624 [-20%], 95% CI: -$2,605, -$586). Direct medical out-of-hospital and direct nonmedical costs were low in both groups (mean cost difference, $156 in favor of hysterectomy). The costs related to absence from work differed significantly between the treatment strategies in favor of UAE (mean difference, -$5,453; 95% CI: -$7,718, -$3,107). The costs of absence from work accounted for 79% of the difference in total costs. The 24-month cumulative cost of UAE is lower than that of hysterectomy. From a societal economic perspective, UAE is the superior treatment strategy in women with

    Data charts of 64 patients with stage I glottic cancer treated with Manchester irradiation modality in the 1 st Radiotherapy Clinic of Msc Memorial Institute in Gliwice has been retrospectively analyzed. There were 55 males and 9 females at median age 63 years (range from 37 to 83 years). In 40 (62%) patients pathological subtype of squamous cell cancer has not been established. In 19 (30%) patients microscopic examination revealed keratinizing and in 5 (8%) nonkeratinizing type of neoplasm. In 49 (77%) patients the tumour involved only one vocal cord, in 11 (17%) both, in 3 (5%) vocal cord and commissure and 1 (1%) patient both cords and commissure. All patients were treated with 60C o machines (36 patients - 56%) or high energy photons (28 patients - 44%). Radiotherapy was conducted with so called Manchester modality with one daily fraction of 3 Gy to a total dose of 51-54 Gy. Overall treatment time varied between 21 and 23 days. Acute mucosal reaction was evaluated with the morphological-functional Dische scale as well as with the EORTC/RTOG scoring system. The criteria of treatment efficacy were: 5-year local control, 5-year survival without serious complications (3 and 4 EORTC) and 5-year survival after salvage surgery in relapsed patients. In 63 patients complete regression of the tumour was observed up to 6 months of follow-up. One patient failed at the time of radiotherapy ending. In one case distant metastases to lungs were noticed. In 6 patients local relapses were discovered of which 3 were successfully salvaged with the surgery. In one patient, 18 months after radiotherapy massive oedema of laryngeal mucosa occurred. In this case tracheostomy was needed. 5-year local control, local control after salvage surgery and survival without serious complication rates are 89%, 97% and 95% respectively. 1. Radiotherapy with Manchester modality is a safe and effective treatment of stage I glottic cancer. 2. Despite hypofractionation the risk of severe complication

    We have conducted experiments to evaluate the effectiveness of removing contaminated soils from the Nevada Test Site with a large truck-mounted vacuum cleaner. Our results show that this method is effective, relatively easy, and safe for equipment operators. With four passes of the truck-mounted vacuum, 92% of the 241Am (and the accompanying 239 + 240Pu) was removed and resuspension rates were reduced by more than 99%. The ecological impact was, however, serious in terms of soil erosion and destruction of small animal habitats. Compared to standard earth-moving techniques, vacuuming permits a significant reduction in the volume of soil collected to achieve the desired level of decontamination, and the volume reduction could result in cost savings for packaging, shipment, and burial. This cost savings would only be realized for projects involving decontamination of the top 5 cm of soil

    Full Text Available Introduction: With improving survival of rectal cancer, functional outcome has become in- creasingly important. Following sphincter-preserving resection many patients suffer from severe bowel dysfunction with an impact on quality of life (QoL – referred to as low ante- rior resection syndrome (LARS. Study objective: To provide an overview of the current knowledge of LARS regarding symp- tomatology, occurrence, risk factors, pathophysiology, evaluation instruments and treat- ment options. Results: LARS is characterized by urgency, frequent bowel movements, emptying difficulties and incontinence, and occurs in up to 50-75% of patients on a long-term basis. Known risk factors are low anastomosis, use of radiotherapy, direct nerve injury and straight anasto- mosis. The pathophysiology seems to be multifactorial, with elements of anatomical, sen- sory and motility dysfunction. Use of validated instruments for evaluation of LARS is es- sential. Currently, there is a lack of evidence for treatment of LARS. Yet, transanal irrigation and sacral nerve stimulation are promising. Conclusion: LARS is a common problem following sphincter-preserving resection. All pa- tients should be informed about the risk of LARS before surgery, and routinely be screened for LARS postoperatively. Patients with severe LARS should be offered treatment in order to improve QoL. Future focus should be on the possibilities of non-resectional treatment in order to prevent LARS.

    To evaluate the 12-week outcomes (effectiveness, tolerability, and patterns of medication use) of olanzapine (either in antimanic monotherapy or in combination with other antipsychotics, anticonvulsants, and/or lithium) in patients with bipolar mania or mixed mania. EMBLEM (European Mania in Bipolar Longitudinal Evaluation of Medication) is a 24-month prospective observational study of in- and outpatients with acute mania/mixed mania conducted in 14 European countries. Primary outcome measures included Clinical Global Impressions-Bipolar Disorder scale (overall, mania, and depression); 5-item Hamilton Depression Rating Scale; and Young Mania Rating Scale. Tolerability measures included a questionnaire to assess patients' symptomatic complaints. Overall, 2004 patients received olanzapine (olanzapine monotherapy, n=673; olanzapine combination, n=1331). Concomitant therapy with antidepressants and/or anxiolytics was possible in both groups. The countries significantly differed in the use of olanzapine monotherapy versus olanzapine combination (pEMBLEM results suggest that in naturalistic settings, olanzapine (both as monotherapy and combination) may be effective in treating patients with bipolar mania. The use of olanzapine monotherapy or combination varies significantly across countries, but combination is generally the rule, rather than the exception.

    To evaluate, from a societal perspective, the incremental cost-effectiveness of withdrawing tumor necrosis factor inhibitors (TNFis) compared to continuation of these drugs within a one-year randomized trial among patients with rheumatoid arthritis (RA) having longstanding stable disease activity or remission. Data were collected from a pragmatic, open label trial. Cost-utility analysis was performed using the non-parametric bootstrapping method and a cost-effectiveness acceptability curve was constructed using the net-monetary benefit (NMB) framework, where a willingness-to-accept threshold (WTA) was defined as the minimal cost saved that a patient accepted for each quality-adjusted life year (QALY) lost. 531 patients were randomized to the Stop Group and 186 patients to the Continue Group. Withdrawal of TNFis resulted in more than 60% reduction of the total drug cost, but led to an increase of about 30% in the other healthcare expenditure. Compared to continuation, stopping TNFis resulted in a mean yearly cost saving of €7,133 (95% CI, [€6,071, €8,234]) and was associated with a mean loss of QALYs of 0.02 (95% CI, [0.002, 0.040]). Mean saved cost [95% CI] per QALY lost and per extra flare incurred in the Stop group compared to the Continuation group was €368,269 [€155,132, €1,675,909] and €17,670 [€13,650, €22,721], respectively. At a WTA of €98,438 per QALY lost, the probability that stopping TNFis is cost-effective was 100%. Although an official WTA is not defined, the mean saved cost of €368,269 per QALY lost seems acceptable in The Netherlands, given existing data on the willingness-to-pay.

    To describe the clinical and procedural coronary chronic total occlusion (CTO) treatment results in a Nordic PCI centre during the implementation of a CTO treatment program. In a retrospective registry study, we assessed; (1) indication for the procedure, (2) Canadian Cardiovascular Society angina pectoris score (CCS)/New York Heart Association (NYHA) heart failure score, (3) lesion complexity and (4) adverse events during hospital stay and three months following the index procedure. The study cohort included 503 patients (594 lesions). From 2010 to 2013 96% of procedures were performed with antegrade wire-escalation technique and 4% performed using retrograde techniques, from 2013-2016 the corresponding numbers were 83% and 17.0%. The procedural success rate was 69%, increasing from 64% before to 72% (p = .06) after routinely using the retrograde approach. No individual patient characteristic, lesion variable or score was strongly associated with procedural success or failure. There were 4% serious procedure related complications. In patients with PCI of a CTO lesion only, 87% were in CCS or NYHA functional class ≥2 before the index procedure vs. 22% at follow-up. Routine use of retrograde techniques tended to increase the procedural success rate. Clinical results after three months were acceptable, but the complication rate was higher than for non-CTO PCI. Individual patient and lesion characteristics had a low predictability for procedural success. Therefore, clinical symptoms, objective signs of myocardial ischemia and procedural risk should be focus points in coronary chronic total occlusion treatment strategies.

    Radiation-induced liver disease (RILD), often called radiation hepatitis, is a syndrome characterized by the development of anicteric ascites approximately 2 weeks to 4 months after hepatic irradiation. There has been a renewed interest in hepatic irradiation because of two significant advances in cancer treatment: three dimensional radiation therapy treatment planning and bone marrow transplantation using total body irradiation. RILD resulting from liver radiation can usually be distinguished clinically from that resulting from the preparative regime associated with bone marrow transplantation. However, both syndromes demonstrate the same pathological lesion: veno-occlusive disease. Recent evidence suggests that elevated transforming growth factor β levels may play a role in the development of veno-occlusive disease. Three dimensional treatment planning offers the potential to determine the radiation dose and volume dependence of RILD, permitting the safe delivery of high doses of radiation to parts of the liver. The chief therapy for RILD is diuretics, although some advocate steroids for severe cases. The characteristics of RILD permit the development of a grading system modeled after the NCI Acute Common Toxicity Criteria, which incorporates standard criteria of hepatic dysfunction

    Full Text Available The TATE trial was a multicentre pragmatic randomized controlled trial of supplementing primary care management (PCM-consisting of a GP consultation followed by information and advice on exercises-with transcutaneous electrical nerve stimulation (TENS, to reduce pain intensity in patients with tennis elbow. This paper reports the health economic evaluation.Adults with new diagnosis of tennis elbow were recruited from 38 general practices in the UK, and randomly allocated to PCM (n = 120 or PCM plus TENS (n = 121. Outcomes included reduction in pain intensity and quality-adjusted-life-years (QALYs based on the EQ5D and SF6D. Two economic perspectives were evaluated: (i healthcare-inclusive of NHS and private health costs for the tennis elbow; (ii societal-healthcare costs plus productivity losses through work absenteeism. Mean outcome and cost differences between the groups were evaluated using a multiple imputed dataset as the base case evaluation, with uncertainty represented in cost-effectiveness planes and through probabilistic cost-effectiveness acceptability curves. Incremental healthcare cost was £33 (95%CI -40, 106 and societal cost £65 (95%CI -307, 176 for PCM plus TENS. Mean differences in outcome were: 0.11 (95%CI -0.13, 0.35 for change in pain (0-10 pain scale; -0.015 (95%CI -0.058, 0.029 for QALYEQ5D; 0.007 (95%CI -0.022, 0.035 for QALYSF6D (higher score differences denote greater benefit for PCM plus TENS. The ICER (incremental cost effectiveness ratio for the main evaluation of mean difference in societal cost (£ relative to mean difference in pain outcome was -582 (95%CI -8666, 8113. However, incremental ICERs show differences in cost-effectiveness of additional TENS, according to the outcome being evaluated.Our findings do not provide evidence for or against the cost-effectiveness of TENS as an adjunct to primary care management of tennis elbow.

    The aim of this study was to assess the long term results of treatment and rehabilitation of childhood dysphonia. This study included a group of adolescents (n=29) aged from 15 to 20 who were treated due to pediatric hyperfunctional dysphonia and soft vocal fold nodules during their pre-mutational period (i.e. between 5 and 12 years of age). The pre-mutational therapy was comprised of proper breathing pattern training, voice exercises and psychological counseling. Laryngostroboscopic examination and perceptual analysis of voice were performed in each patient before treatment and one to four years after mutation was complete. The laryngostroboscopic findings, i.e. symmetry, amplitude, mucosal wave and vocal fold closure, were graded with NAPZ scale, and the GRBAS scale was used for the perceptual voice analysis. Complete regression of the childhood dysphonia was observed in all male patients (n=14). Voice disorders regressed completely also in 8 out of 15 girls, but symptoms of dysphonia documented on perceptual scale persisted in the remaining seven patients. Complex voice therapy implemented in adolescence should be considered as either the treatment or preventive measure of persistent voice strain, especially in girls.

    We performed sixty patients with hematological malignancies the total body irradiation prior to bone marrow transplantation (TBI-BMT) from 1988 to 2000. We delivered our each patient hyperfractionated TBI consisting of 2 fractions of 3 Gy per day for 2 consecutive days following induction chemotherapy. It proved that TBI-BMT was a valuable treatment method for hematological malignancies which have poor prognosis. About the cumulative survival rate, patients of first remission were better outcome than patients beyond second remission. However, the therapy remained some problems which were the prophylaxis of GVHD for HLA-matched unrelated recipients. And we have to consider a new maintenance procedure to prevent relapse from transplanted donor cell. (author)

    Purpose: to evaluate the delayed toxicity of two patterns of adjuvant radiotherapy including a breast irradiation, at the dose of 48 Gy in 20 seances and five weeks or 57.60 Gy in 24 seances and six weeks in case of majored factors of local recurrence risk. The secondary objective were the auto evaluation by the patient of the esthetic result and the influence of this last one on the quality of life. Conclusion: the delayed toxicity was dominated by the fibrosis low to moderated one, without any significant difference between the doses of 48 Gy and 57.60 Gy. The esthetic result evaluated by the patient, globally good, seemed however, damaged with the last pattern. A bad esthetic result, without affected the global quality of life was associated to more specific breast symptoms and damaged the perception of the body image. (N.C.)

The purpose of the study was to compare intra- articular AC repair technique with the extra-articular coracoclavicular repair technique for the patients with Rockwood type III and VAC joint injury when indicated.Methods: Nineteen consecutive patients with Rockwood type III and VAC joint injury  were treated with intra-articular (Group I - 12 cases and extra-articular (Group II - 7cases repair technique between 1380 - 1386, and the results reviewed. When the diagnosis was established, the mean age of the patients was 32.5 years (Range, 18 - 60; group I and II 31.8 years (Range, 18 - 60 and 34 years (Range, 22 - 58 respectively. The mean duration of postoperative follow - up was 24 months. The Constant shoulder scoring system was applied to obtain clinical results.   Results: Only in group I, the post-surgical complication was associated with fiber allergy, wound infection and pin site infection in two patients respectively. No pain was detected in fourteen cases. Four patients in group I had occasional mild pain during sport activity, while one case in this group reported severe pain during resting which prevented the patient from activity. Also, there was an ossification in thirteen patients particularly in group I. Clinical results showed the mean constant shoulder score was 93.4 in group I and 97.1 in group II.Conclusion: At the time of the follow - up, there was a clear difference between both groups regarding to postoperative pain and discomfort.Therefore, it seemed that potential cause of pain was due to postoperative complications. An interesting postoperative complication without interfere in the functional outcome was coracoclavicular space ossification in most cases. This was probably because of soft tissue injury during the operation.It seemed that surgical treatment of Rockwood type III and VAC joint injuries

    Previous research has reported that ease of use of and preference for a delivery device are associated with greater patient compliance – an important factor in achieving optimal therapeutic results. The objective of this study was to assess the ease-of-use of a new disposable pen (GoQuick®, Pfizer, Inc.) versus the current reusable pen (GENOTROPIN Pen®, Pfizer, Inc.) to inject a daily dose of recombinant DNA origin human growth hormone, Genotropin® (somatropin) in standard practice. In this randomized, crossover, multicenter, multinational, open-label study, ease-of-use of and preference for the two pens were assessed in three treatment-naïve populations: 1) parents of very young children; 2) parent–child dyads; and 3) adults via use of a validated self-report Injection Pen Assessment Questionnaire (IPAQ) after 2 months of at-home-use experience. The primary endpoint was the proportion of participants who reported the new disposable pen to be no different from or easier to use than the current reusable pen. Safety was also assessed and reported according to local legal requirements. Of the 120 screened patients, 119 were included in the ease-of-use analysis and all were included in the safety analyses. In all, 67.2% found the new somatropin disposable pen to be no different from or easier to use than the reusable pen (95% confidence interval: 58.8–75.7). Most adverse events were mild or moderate. No deaths or device- or treatment-related serious adverse events were reported. These results suggest that improvements made to the reusable somatropin pen are tangible and recognizable to treatment-naïve patients and their caregivers, child–caregiver dyads, and adults, and may positively impact continued compliance with therapy.

    1995-08-01

    This report presents the second phase of a study on thermal treatment technologies. The study consists of a systematic assessment of nineteen thermal treatment alternatives for the contact-handled mixed low-level waste (MLLW) currently stored in the US Department of Energy complex. The treatment alternatives consist of widely varying technologies for safely destroying the hazardous organic components, reducing the volume, and preparing for final disposal of the MLLW. The alternatives considered in Phase 2 were innovative thermal treatments with nine types of primary processing units. Other variations in the study examined the effect of combustion gas, air pollution control system design, and stabilization technology for the treatment residues. The Phase 1 study, the results of which have been published as an interim report, examined ten initial thermal treatment alternatives. The Phase 2 systems were evaluated in essentially the same manner as the Phase 2 systems. The assumptions and methods were the same as for the Phase 1 study. The quantities, and physical and chemical compositions, of the input waste used in he Phase 2 systems differ from those in the Phase 1 systems, which were based on a preliminary waste input database developed at the onset of the Integrated Thermal Treatment System study. The inventory database used in the Phase 2 study incorporates the latest US Department of Energy information. All systems, both primary treatment systems and subsystem inputs, have now been evaluated using the same waste input (2,927 lb/hr).

    This report presents the second phase of a study on thermal treatment technologies. The study consists of a systematic assessment of nineteen thermal treatment alternatives for the contact-handled mixed low-level waste (MLLW) currently stored in the US Department of Energy complex. The treatment alternatives consist of widely varying technologies for safely destroying the hazardous organic components, reducing the volume, and preparing for final disposal of the MLLW. The alternatives considered in Phase 2 were innovative thermal treatments with nine types of primary processing units. Other variations in the study examined the effect of combustion gas, air pollution control system design, and stabilization technology for the treatment residues. The Phase 1 study, the results of which have been published as an interim report, examined ten initial thermal treatment alternatives. The Phase 2 systems were evaluated in essentially the same manner as the Phase 2 systems. The assumptions and methods were the same as for the Phase 1 study. The quantities, and physical and chemical compositions, of the input waste used in he Phase 2 systems differ from those in the Phase 1 systems, which were based on a preliminary waste input database developed at the onset of the Integrated Thermal Treatment System study. The inventory database used in the Phase 2 study incorporates the latest US Department of Energy information. All systems, both primary treatment systems and subsystem inputs, have now been evaluated using the same waste input (2,927 lb/hr)

    The US Nuclear Regulatory Commission (NRC), Sandia National Laboratories (SNL), and General Physics Corporation are conducting a research program to determine the practicality, acceptability, and usefulness of a Human Reliability Data Bank for nuclear power industry probabilistic risk assessment (PRA). As part of this program, a survey was conducted of existing human reliability data banks from other industries, and a detailed concept of a Data Bank for the nuclear industry was developed. Subsequently, a detailed specification for implementing the Data Bank was developed. An evaluation of this specification was conducted and is described in this report. The evaluation tested data treatment, storage, and retrieval using the Data Bank structure, as modified from NUREG/CR-2744, and detailed procedures for data processing and retrieval, developed prior to this evaluation and documented in the test specification. The evaluation consisted of an Operability Demonstration and Evaluation of the data processing procedures, a Data Retrieval Demonstration and Evaluation, a Retrospective Analysis that included a survey of organizations currently operating data banks for the nuclear power industry, and an Internal Analysis of the current Data Bank System

    Purpose/Objective: To assess the prognostic factors and treatment results of thymoma with emphasis on surgery and radiotherapy. Materials and Methods: Thymoma patients treated at Duesseldorf University Hospital from 1954 to 1991 were studied in this retrospective analysis. Depending on stage and residual disease, treatment was surgery (sternotomy or thoracotomy) with and without radiotherapy and chemotherapy (Holoxan, Endoxan, Vinblastin, Adriamycin, Bleomycin, CDDP, Vepesid). 70 patients (38f, 32m) were enrolled in this study. The mean age was 46,5 years. At presentation the median Karnofsky's index was 90%. In 19% thymoma was accidentally diagnosed, 81% presented symptoms at diagnosis. Masaoka's staging system was used (I: intact capsule; II: invasion of the capsule; III: invasion of neighboring organs; IV: dissemination). Stage at presentation was I:21%; II: 26%; III: 43%; IV: 10%. All histologic slices were peer reviewed. Histologic classification according to Lewis (predominantly lymphocytic: 36%; predominantly epithelial: 23%; mixed type: 33%, spindle cell thymoma: 9%) was applied. All available paraffin embedded specimens (36) were studied with DNA cytometric analysis after Feulgen staining. Occasionally thymoma was accompanied by Myasthenia gravis (23%) or other paraneoplastic syndromes (19%). Statistical analysis was performed using the Kaplan-Meier method and logrank-tests. Multivariate analysis was also performed. Results: From 70 patients treated surgically, 68% were radically resected (R0), 26% incompletely resected (R1,2) and 6% had biopsy only. The median cause specific survival (CSS) was 132 months. All patients with localized disease (stage I and II) were completely resected and received no further therapy, whereas only 50% (15 pat) in stage III and 0% in stage IV were amenable to radical resection. 36% (25 pat) received an additional therapy (CMT): 31% (22 pat) postoperative irradiation and 4% (3 pat) combined radio-chemotherapy.

    Introduction: Cervical cancer in women occupies 3rd place in incidence and 5th as a cause of cancer death in our country. The evolution is mainly determined by the stage, nodal status and histological type. The treatment of these tumors is surgical, radiant and / or systemic, depending on your choice mainly Stadium. Objective: To analyze the characteristics, evolution, treatment and survival of patients carriers of cervical cancer. Patients and Methods: The medical records were retrospectively analyzed for patients with cervical cancer treated at the Department of Oncology the Clinical Hospital in the period 1994-2004. Curves were constructed survival (sv) of total and free enfemedad sv sv by stage and after relapse by the method of Kaplan-Meier. Results: n = 75 patients, median age 45 years (24-90 years). Histological type: Epidermoid carcinomas 93% 5% 2% adenocarcinomas and adenosquamous. stadium (E) Initial: 31% IE, 38% EII, EIII 25%, 6% EIVA. Treatment was according to the stadium, considering that until 1999 was not standard concurrent chemoradiation. The median sv considering all stages was 124 months. The sv to 5 years for EI was 90% (median 188 sv months), for the ISI 65% (95 months) and the median sv CIRTs was 24 months. Followed for 13 months, 12 patients relapsed and the median after sv relapse was 8 months (95% CI 4-13 months) Conclusions: Although cervical cancer is a preventable disease, remains an important cause of morbidity and mortality. Our results are consistent with those reported in the literature, however far from the optimal, so it is necessary to continue clinical trials in this regard

    generated by a mathematical model of the competitive growth of multiple strains of Escherichia coli.Results: Simulation studies showed that sequential use of tetracycline and ampicillin reduced the level of double resistance, when compared to the combination treatment. The effect of the cycling frequency...... frequency did not play a role in suppressing the growth of resistant strains, but the specific order of the two antimicrobials did. Predictions made from the study could be used to redesign multidrug treatment strategies not only for intramuscular treatment in pigs, but also for other dosing routes.......Background: Combination treatment is increasingly used to fight infections caused by bacteria resistant to two or more antimicrobials. While multiple studies have evaluated treatment strategies to minimize the emergence of resistant strains for single antimicrobial treatment, fewer studies have...

    Full Text Available The purpose of this study was to offer preliminary support for the Louisiana Sex Offender Treatment Program (LSOTP in addressing the needs of juvenile sex offenders. Research objectives were (1 to offer statistical evidence for reductions in anxiety, depression, cognitive distortion and negative attitudes towards women comparing a group of 21 adolescents, 12 of whom received services as usual and nine of whom participated in the LSOTP. A controlled experimental evaluation design was utilized. The juvenile sex offenders were randomly assigned to the experimental group for 12 weeks receiving treatment services and a control group receiving care “as usual” in a residential group care program. Participants in the experimental group experienced statistically significant decreases in cognitive distortions related specifically to rape and molestation.The results of this study offer preliminary support of the LSOTP as a best practices alternative to other treatment modalities.

  8. Intracavitary radiation treatment planning and dose evaluation

    1987-01-01

    Intracavitary radiation therapy with encapsulated radionuclide sources has generally involved, since the advent of afterloading techniques, inserting the sources in tubing previously positioned within a body cavity near the region to be treated. Because of the constraints on source locations relative to the target region, the functions of treatment planning and dose evaluation, usually clearly separable in interstitial brachytherapy, tend to merge in intracavitary therapy. Dose evaluation is typically performed for multiple source-strength configurations in the process of planning and thus may be regarded as complete when a particular configuration has been selected. The input data for each dose evaluation, of course, must include reliable dose distribution information for the source-applicator combinations used. Ultimately, the goal is to discover the source-strength configuration that results in the closest possible approach to the dose distribution desired

    1992-01-01

    Empirical Critical Heat Flux (CHF) correlations PI-3 having the widest range of validity for flow conditions in both hexagonal and square rod bundle geometries and compared with published CHF correlations are presented. They are valid for vertical water upflow through rod bundles with relatively wide and very tight rod lattices, and include axial and radial non-uniform heating. The correlations were developed with the use of more than 6000 data obtained from 119 electrically heated rod bundles. Comprehensive results of statistical evaluations of the new correlations are presented for various data bases. Also presented is a comparison of statistical evaluations of several well-known CHF correlations in the experimental data base used. A procedure which makes it possible to directly determine the probability that CHF does not occur is described for the purpose of nuclear safety assessment. (author) 8 tabs., 32 figs., 11 refs

    O'Brien, S; Ross, L V; Christophersen, E R

    1986-01-01

    Cathartic and behavioral treatment procedures for eliminating diurnal and nocturnal primary encopresis were investigated using a multiple-baseline design across four children. The dependent and independent variables measured were appropriate bowel movements, soiling accidents, independent toiletings, and cathartic use. Over 177 reliability observations (home visits) were conducted. For two of the children, treatment with cathartics and child-time remedied their soiling accidents and increased their independent toiletings in 8 to 11 weeks. While the cathartics and child-time increased the rate of appropriate bowel movements, they did not eliminate the soiling accidents with the other two children. Independent toiletings for these two children were achieved after 32 to 39 weeks of treatment when punishment procedures (positive practice, time-out, and hourly toilet sits) were incorporated and the suppositories were faded systematically.

    In recent years, no major advances have been made in understanding the mechanisms underlying the development of tinnitus. Hence, the present therapeutic strategies aim at decoupling the subconscious from the perception of tinnitus. Mindful of the lessons drawn from existing tinnitus retraining and desensitisation therapies, a new integrated day hospital strategy of treatment lasting 7-14 days has been developed at the Charité Hospital and is presented in the present paper. The strategy for treating tinnitus in the proximity of patient domicile is designed for patients who feel disturbed in their world of perception and their efficiency due to tinnitus and give evidence of mental and physical strain. In view of the etiologically non-uniform and multiple events connected with tinnitus, consideration was also given to the fact that somatic and psychosocial factors are equally involved. Therefore, therapy should aim at diagnosing and therapeutically influencing those psychosocial factors that reduce the hearing impression to such an extent that the affected persons suffer from strain. The first results of therapy-dependent changes of 46 patients suffering from chronic tinnitus are presented. The data were evaluated before and after 7 days of treatment and 6 months after the end of treatment. Immediately after the treatment, the scores of both the tinnitus questionnaire (Goebel and Hiller) and the subscales improved significantly. These results were maintained during the 6-month post-treatment period and even improved.

  12. Evaluation and treatment of enuresis.

    Ramakrishnan, Kalyanakrishnan

    2008-08-15

    Enuresis is defined as repeated, spontaneous voiding of urine during sleep in a child five years or older. It affects 5 to 7 million children in the United States. Primary nocturnal enuresis is caused by a disparity between bladder capacity and nocturnal urine production and failure of the child to awaken in response to a full bladder. Less commonly, enuresis is secondary to a medical, psychological, or behavioral problem. A diagnosis usually can be made with a history focusing on enuresis and a physical examination followed by urinalysis. Imaging and urodynamic studies generally are not needed unless specifically indicated (e.g., to exclude suspected neurologic or urologic disease). Primary nocturnal enuresis almost always resolves spontaneously over time. Treatment should be delayed until the child is able and willing to adhere to the treatment program; medications are rarely indicated in children younger than seven years. If the condition is not distressing to the child, treatment is not needed. However, parents should be reassured about their child's physical and emotional health and counseled about eliminating guilt, shame, and punishment. Enuresis alarms are effective in children with primary nocturnal enuresis and should be considered for older, motivated children from cooperative families when behavioral measures are unsuccessful. Desmopressin is most effective in children with nocturnal polyuria and normal bladder capacity. Patients respond to desmopressin more quickly than to alarm systems. Combined treatment is effective for resistant cases.

    Excellent treatment results have been acieved historically with postoperative radiotherapy in testicular seminoma. In this retrospective study the treatment results of 211 patients with Stage I/II testicular seminoma treated in Finland during the years 1970-1983 were evaluated. 176 (84%) patients received postoperative radiotherapy alone. In addition to radiotherapy, 26 (12%) patients received chemotherapy during the primary treatment. There were 129 Stage I (61%), 66 Stage IIA-B (31%) and 16 Stage IIC (8%) tumors. The 5-year survival rate was 95% in Stage I, 87% in Stage IIA-B and 73% in Stage IIC. In Stage I, seven relapses (relapse rate 6%) occured after irradiation; three of them were cured with second-line therapies. None of the relapses occurred within the radiotherapy field. In Stage IIA-B, 31 patients had only parailiacic + aortic irradiation, 25 patients received both parailiacic + aortic and mediastinal irradiation. With both radiotherapy techniques there was no significant difference in the number of relapses (seven and three) and in the remission rate (94% and 96%). Radiotherapy alone was used on four Stage IIC patients and one of them died during the primary treatment. Two of them relapsed, but could be cured with chemotherapy. These results correspond to those reported in the literature and tye suggest that prophylactic mediastinal irradiation is unneccessary in Stage IIA-B patients. Stage IIC patients should receive chemotherapy initially. (author). 19 refs.; 2 figs.; 2 tabs

  14. Clinical evaluation of treatment plans

    1966-06-15

    Since the start of radiotherapy, the aim of all radiotherapists has been to treat as many patients who suffer with malignant tumours as possible, so as to give an effective curative dose to the whole tumour, at the same time, doing as little damage as possible to normal tissues. Until 1945, damage to the skin was usually the limiting factor. Since the war, with the rapid development of more powerful X-ray machines and sources of irradiation, we have had at our disposal much more penetrating radiation, allowing us to give effective tumour doses, with little or no damage to the skin. However, with higher tumour doses, there is more likelihood of damage to structures in proximity to the tumour - i.e. bone, nerves, muscle, liver, kidney etc. This has focussed the interest of all radiologists on the need for careful planning, and physicists have worked out with great care the differential absorptions of X-rays on differing tissue, i. e. bone, muscle, fat etc., so that very accurate and correct treatment planning can now be undertaken. This entails a great deal of accurate and complicated work and has had to be done by our physicist colleagues, who may take hours or days to work out a complicated treatment plan. The acceptance of the plan as being the most suitable for a patient is governed by these factors: (a) The dose must be given to the whole tumour area; (b) The nearby structures, i. e. nerves, bowel, kidney etc. must not receive a dose which may cause serious damage; (c) All parts of the tumour must have an effective dose; (d) The integral dose must be such that the patient is not unduly upset. All these factors vary from patient to patient, and thus each plan has to be considered in conjunction with each individual patient so that, although patients have similar tumours, what may be an optimal plan for one may not be for another. Also clinicians themselves vary in their opinions on the size of tumour, general condition of the patient, and the amount of damage

    PURPOSE OF THE STUDY This retrospective study aims to present short-term clinical outcomes of endoscopic treatment of patients with greater trochanteric pain syndrome (GTPS). MATERIAL AND METHODS The evaluated study population was composed of a total of 19 patients (16 women, 3 men) with the mean age of 47 years (19-63 years). In twelve cases the right hip joint was affected, in the remaining seven cases it was the left side. The retrospective evaluation was carried out only in patients with greater trochanteric pain syndrome caused by independent chronic trochanteric bursitis without the presence of m. gluteus medius tear not responding to at least 3 months of conservative treatment. In patients from the followed-up study population, endoscopic trochanteric bursectomy was performed alone or in combination with iliotibial band release. The clinical results were evaluated preoperatively and with a minimum follow-up period of 1 year after the surgery (mean 16 months). The Visual Analogue Scale (VAS) for assessment of pain and WOMAC (Western Ontario MacMaster) score were used. In both the evaluated criteria (VAS and WOMAC score) preoperative and postoperative results were compared. Moreover, duration of surgery and presence of postoperative complications were assessed. Statistical evaluation of clinical results was carried out by an independent statistician. In order to compare the parameter of WOMAC score and VAS pre- and post-operatively the Mann-Whitney Exact Test was used. The statistical significance was set at 0.05. RESULTS The preoperative VAS score ranged 5-9 (mean 7.6) and the postoperative VAS ranged 0-5 (mean 2.3). The WOMAC score ranged 56.3-69.7 (mean 64.2) preoperatively and 79.8-98.3 (mean 89.7) postoperatively. When both the evaluated parameters of VAS and WOMAC score were compared in time, a statistically significant improvement (ppain syndrome yields statistically significant improvement of clinical results with the concurrent minimum incidence of

    Background: Use of engineered nanoparticles (NPs) in consumer products is resulting in NPs in drinking water sources. Subsequent NP breakthrough into treated drinking water is a potential exposure route and human health threat. Objectives: In this study we investigated the breakthrough of common NPs—silver (Ag), titanium dioxide (TiO2), and zinc oxide (ZnO)—into finished drinking water following conventional and advanced treatment. Methods: NPs were spiked into five experimental waters: groundwater, surface water, synthetic freshwater, synthetic freshwater containing natural organic matter, and tertiary wastewater effluent. Bench-scale coagulation/flocculation/sedimentation simulated conventional treatment, and microfiltration (MF) and ultrafiltration (UF) simulated advanced treatment. We monitored breakthrough of NPs into treated water by turbidity removal and inductively coupled plasma–mass spectrometry (ICP-MS). Results: Conventional treatment resulted in 2–20%, 3–8%, and 48–99% of Ag, TiO2, and ZnO NPs, respectively, or their dissolved ions remaining in finished water. Breakthrough following MF was 1–45% for Ag, 0–44% for TiO2, and 36–83% for ZnO. With UF, NP breakthrough was 0–2%, 0–4%, and 2–96% for Ag, TiO2, and ZnO, respectively. Variability was dependent on NP stability, with less breakthrough of aggregated NPs compared with stable NPs and dissolved NP ions. Conclusions: Although a majority of aggregated or stable NPs were removed by simulated conventional and advanced treatment, NP metals were detectable in finished water. As environmental NP concentrations increase, we need to consider NPs as emerging drinking water contaminants and determine appropriate drinking water treatment processes to fully remove NPs in order to reduce their potential harmful health outcomes.

    Full Text Available Behavioral treatments for obesity are not evaluated by the same criteria as pharmaceutical drugs, even though treatments such as low-calorie dieting are widely prescribed, require the patients’ time and investment, and may have risks. The Food and Drug Administration (FDA has a procedure for evaluating drugs, in which drugmakers must answer the following questions: (1 Is the treatment safe? (2 How dangerous is the condition the intervention is treating? (3 Is the treatment effective? (4 Is the treatment safe and effective for large numbers of people? We argue that using this framework to evaluate behavioral interventions could help identify unanswered research questions on their efficacy and effectiveness, and we use the example of low-calorie dieting to illustrate how FDA criteria might be applied in the context of behavioral medicine.

    Purpose: In contrast with many analyses of surgical treatment for spinal metastases, there have been only a few recent well-documented publications assessing nonsurgical treatment. This paper is a study of the outcome of nonsurgical therapy for metastatic tumors of the spine. Methods and Materials: One hundred and one patients with spinal metastases were treated with radiation therapy and/or chemotherapy without surgical intervention between 1990 and 1995, in prospective analysis, and had follow-up for more than 24 months. This study included 59 men and 42 women with a mean age of 61 years (range: 14 to 81). Mean follow-up periods were 11 months for patients dying of the disease and 53 months for the survivors. Neurological status, pain relief, functional improvement, and cumulative survival rate were assessed. Results: Of the total treated, 67 patients (66%) were evaluated as being neurologically stable or improved after treatment. Pain relief was achieved in 67%, and 64% showed functional improvement. Primary lesion responsiveness to nonsurgical therapy influenced the survival, neurological recovery, pain control, and function. Neurological findings before therapy were useful in predicting ambulatory status after treatment. Conclusion: Nonsurgical treatment was often successful when primary tumors had responsiveness to radiation therapy and/or chemotherapy. We found this to be evident even when neurological deficits were found, particularly in lumbar spines. Spinal metastases of tumors with less responsiveness, unless patients were neurologically intact, responded poorly to therapy. Most of the patients who were successfully treated enjoyed relief lasting nearly until death. Their functional ability was limited by general debility, rather than by local tumor regeneration

    Irreversible electroporation (IRE) is an ablative therapy with a low side-effect profile in prostate cancer. The objective was: 1) To compare the volumetric IRE ablation zone on grey-scale transrectal ultrasound (TRUS), contrast-enhanced ultrasound (CEUS) and multiparametric MRI (mpMRI) with histopathology findings; 2) To determine a reliable imaging modality to visualize the IRE ablation effects accurately. A prospective phase I-II study was performed in 16 patients scheduled for radical prostatectomy (RP). IRE of the prostate was performed 4 weeks before RP. Prior to, and 4 weeks after the IRE treatment, imaging was performed by TRUS, CEUS, and mpMRI. 3D-analysis of the ablation volumes on imaging and on H and E-stained whole-mount sections was performed. The volumes were compared and the correlation was calculated. Evaluation of the imaging demonstrated that with T2-weighted MRI, dynamic contrast enhanced (DCE) MRI, and CEUS, effects of IRE are visible. T2MRI and CEUS closely match the volumes on histopathology (Pearson correlation r = 0.88 resp. 0.80). However, IRE is not visible with TRUS. mpMRI and CEUS are appropriate for assessing IRE effects and are the most feasible imaging modalities to visualize IRE ablation zone. The imaging is concordant with results of histopathological examination. (orig.)

    Objectives: To provide the experience about the diagnostic process and following management, and to discuss the outcome and predictors in children with laryngeal cleft (LC). Methods: A retrospective case study was conducted at an academic children's hospital. Thirty children were diagnosed as laryngeal cleft between January 2016 and April 2017.Airway evaluations were performed using both flexible and rigid endoscopy, and swallowing evaluations were performed using fiberoptic endoscopic examination of swallowing or modified barium swallow. Results: Of 30 cases, 18 were male and 12 were female, ranging in age from birth to 8 years. Two cases were diagnosed as type 0 LC, and they were offered thickened liquid without medication. Throughout follow-up, they remained asymptomatic and showed no respiratory complications. Nineteen children were diagnosed as type Ⅰ LC. Six of them were significantly improved by anti-reflux therapy and feeding instructions. Four children were concomitant with swallowing dysfunction and/or neuromuscular disorders, and they were given a tracheotomy and routine management. Another 4 children were submitted surgical repair when routine treatment failed, and their symptoms were relieved. Five children were concomitant with larygomalacia, and their symptoms were totally ameliorated by supraglottoplasty. Three children were diagnosed as type Ⅱ LC.

    Full Text Available Introduction: Upper cervical injuries (UCI have a wide range of radiological and clinical presentation due to the unique complex bony, ligamentous and vascular anatomy. We recently proposed a rational approach in an attempt to unify prior classification system and guide treatment. In this paper, we evaluate the clinical results of our algorithm for UCI treatment. Materials and Methods: A prospective cohort series of patients with UCI was performed. The primary outcome was the AIS. Surgical treatment was proposed based on our protocol: Ligamentous injuries (abnormal misalignment, facet perched or locked, increase atlanto-dens interval were treated surgically. Bone fractures without ligamentous injuries were treated with a rigid cervical orthosis, with exception of fractures in the dens base with risk factors for non-union. Results: Twenty-three patients treated initially conservatively had some follow-up (mean of 171 days, range from 60 to 436 days. All of them were neurologically intact. None of the patients developed a new neurological deficit. Fifteen patients were initially surgically treated (mean of 140 days of follow-up, ranging from 60 to 270 days. In the surgical group, preoperatively, 11 (73.3% patients were AIS E, 2 (13.3% AIS C and 2 (13.3% AIS D. At the final follow-up, the American Spine Injury Association (ASIA score was: 13 (86.6% AIS E and 2 (13.3% AIS D. None of the patients had neurological worsening during the follow-up. Conclusions: This prospective cohort suggested that our UCI treatment algorithm can be safely used. Further prospective studies with longer follow-up are necessary to further establish its clinical validity and safety.

    Purpose. To assess the feasibility and effectiveness of emergency endovascular treatment of abdominal aortic aneurysms (AAAs). Methods. During 36 months we treated, on an emergency basis, 30 AAAs with endovascular exclusion. In 21 hemodynamically stable patients preoperative CT angiography (CTA) was performed to confirm the diagnosis and to plan the treatment; 9 patients with hemorrhagic shock were evaluated with angiography performed in the operating room. Twenty-two Excluder (Gore) and 8 Zenith (Cook) stent-grafts (25 bifurcated and 5 aorto-uni-iliac) were used. The follow-up was performed by CTA at 1, 3, 6, and 12 months. Results. Technical success was achieved in 100% of cases with a 10% mortality rate. The total complication rate was 23% (5 increases in serum creatinine level and 2 wound infections). During the follow-up, performed in 27 patients (1-36 months, mean 15.2 months), 4 secondary endoleaks (15%) (3 type II, 2 spontaneously thrombosed and 1 under observation, and 1 type III treated by iliac extender insertion) and 1 iliac leg occlusion (treated with femoro-femoral bypass) occurred. We observed a shrinkage of the aneurysmal sac in 8 of 27 cases and stability in 19 of 27 cases; we did not observe any endotension. Conclusions. Endovascular repair is a good option for emergency treatment of AAAs. The team's experience allows correct planning of the procedure in emergency situations also, with technical results comparable with elective repair. In our experience the bifurcated stent-graft is the device of choice in patients with suitable anatomy because the procedure is less time-consuming than aorto-uni-iliac stent-grafting with surgical crossover, allowing faster aneurysm exclusion. However, further studies are required to demonstrate the long-term efficacy of endovascular repair compared with surgical treatment

    The philosophy pervading the treatment approach to Ewing's sarcoma was to have therapy encompass all foci of disease, including sites of occult or potential involvement in addition to obvious clinical manifestations. The experience with integrated methods of treatment in 66 consecutive patients at the National Cancer Institute is reviewed. A median survival of 18 months (44 percent 2 year survival rate) for patients with recognizable metastases on admission bears impressive witness to the value of adjuvant therapy in Ewing's sarcoma. Even more encouraging, an uncorrected 5 year survival rate of 53 percent (42 percent continuously free of disease) for patients given ''pyrophylactic'', adjuvant therapy indicates the potential for permanent control of disease in a significant fraction of cases with clinically localized primary tumors.

    This study was conducted to evaluate the treatment results, prognostic factors, and complication rates after high dose rate (HDR) brachytherapy in patients with uterine cervix cancer who were treated with curative aim. Of 269 cervix cancer patients treated at the department of radiation oncology, Samsung Medical Center from September 1994 to July 1998, the 106 who were treated with radical radiotherapy were analyzed. The median age was 61 years (range 22 to 89). All patients except 4 with carcinoma in situ (CIS) were given external beam radiotherapy (range 30.6 {approx} 50.4 Gy to whole pelvis) and HDR brachytherapy. The common regimens of HDR brachytherapy were a total dose of 24 {approx} 28 Gy with 6 {approx} 7 fractions to point A at two fractions per week. The median overall treatment time was 55 days (range 44 to 104) in patients given both external beam radiotherapy and HDR brachytherapy. Early response of radiotherapy were evaluated by gynecologic examination and follow-up MRI 1 month after radiotherapy. Treatment responses were complete remission in 72 patients, partial response in 33 and no response in 1. The overall survival (OS) rate of all patients was 82%, and 73%, and the disease free survival (DFS) rate was 72%, and 69%, at 3, and 5 years, respectively. The pelvic control rate (PCR) was 79% at both 3 and 5 years. According to the FIGO stage, 3 and 5 year OS were 100% and 50% in CIS/IA, 100% in 100% in IB, 83% and 69% in IIA, 87% and 80% in IIB, and 62% and 62% in III, respectively. The 3 year OS in 4 patients with stage IVA was 100%. Three-year DFS were 80% in CIS/IA, 88% in IB, 100% in IIA, 64% in IIB, 58% in III, and 75% in IVA. Three-year PCR were 100% in CIS/IA, 94% in IB, 100% in IIA, 84% in IIB, 69% in III, and 50% in IVA. By univariate analysis, FIGO stage and treatment response were significant factors for OS. The significant factors for DFS were age, FIGO stage, treatment response and overall treatment time (OTT). For pelvic control rate

    Vaginal intraepithelial neoplasia (VAIN) represents a variety of changes that initiate as an intraepithelial squamous lesion with the possibility of resulting in cancer. To compare the results of the treatment for the different categories of VAIN with electrocoagulation, 5-fluorouracil and combined treatment. Observational an analytical study. We stablished groups according to the category of VAIN evaluating and comparing remission, persistence, recurrence, or progression of the disease ac- cording to the received treatment, with a 1-year follow up. The results were compared by chi2 and Kruskal Wallis. The statistics analysis was done with the SPSS program version 20. One hundred thirty seven patients between 20 and 81 years of age (mean age: 52.49 years) were included. Seventy-four percent of the patients had a history of premalignant or malignant cervical lesions. Seventy-four patients had VAIN I, 34 patients had VAIN II, 22 patients had VAIN III and there were seven cases of vaginal carcinoma in situ. Fifty-eight patients were treated with electrocoagulation, 55 patients were treated with 5-FU, 16 patients had combined treatment, and eight patients received expectant management. Sixty three percent of patients had total remission of the lesion, 34% had persistence and 3% showed progression, and there were no cases of recurrence. Results were better in patients with VAIN I treated with 5-FU (bigger percentage of remission P .026), for the remaining categories of VAIN, no treatment showed superior results. The superior response occurs in patients with VAIN I treated with 5-FU. None of the treatments achieves a 100% remission. The VAIN frequency is high, patients with a history of malignant or premalignant cervical pathology should undergo a closer surveillance through cytocolposcopic control with respect to the remaining population.

  9. Uncertainty Evaluation of Best Estimate Calculation Results

    2006-01-01

    Efforts are underway in Germany to perform analysis using best estimate computer codes and to include uncertainty evaluation in licensing. The German Reactor Safety Commission (RSK) issued a recommendation to perform uncertainty analysis in loss of coolant accident safety analyses (LOCA), recently. A more general requirement is included in a draft revision of the German Nuclear Regulation which is an activity of the German Ministry of Environment and Reactor Safety (BMU). According to the recommendation of the German RSK to perform safety analyses for LOCA in licensing the following deterministic requirements have still to be applied: Most unfavourable single failure, Unavailability due to preventive maintenance, Break location, Break size and break type, Double ended break, 100 percent through 200 percent, Large, medium and small break, Loss of off-site power, Core power (at accident initiation the most unfavourable conditions and values have to be assumed which may occur under normal operation taking into account the set-points of integral power and power density control. Measurement and calibration errors can be considered statistically), Time of fuel cycle. Analysis using best estimate codes with evaluation of uncertainties is the only way to quantify conservatisms with regard to code models and uncertainties of plant, fuel parameters and decay heat. This is especially the case for approaching licensing limits, e.g. due to power up-rates, higher burn-up and higher enrichment. Broader use of best estimate analysis is therefore envisaged in the future. Since some deterministic unfavourable assumptions regarding availability of NPP systems are still used, some conservatism in best-estimate analyses remains. Methods of uncertainty analyses have been developed and applied by the vendor Framatome ANP as well as by GRS in Germany. The GRS development was sponsored by the German Ministry of Economy and Labour (BMWA). (author)

    This report gives the results of the analysis carried out in the manner described in PISC report no.4, to compare the defects indicated by ultrasonic examination with those discovered by a destructive examination. The analysis was repeated three times; once for ultrasonic examination using the PISC procedure but with as much as possible subjective interpretation from the teams removed, once for ultrasonic examination using the PISC procedure incorporating the subjective interpretation of the teams, and once for ultrasonic examination using a variety of alternative techniques. Results are given in the form of tables and figures for each reference defect (i.e. those found by the destructive examination) in turn. Correlations, when they exist, are presented between the parameters describing the performance of the ultrasonic examination procedures and the parameters describing the reference defects. From the global set of results conclusions are drawn concerning the efficiency of the ultrasonic procedures for detecting, sizing, locating and correct rejection of defects

    NORM is the acronym used to refer to naturally occurring radioactive materials. Besides being objects of study and monitoring such materials can be used as raw material or as by-products or waste of industrial activities. Oil and gas, mining and water treatment are examples of facilities that can handle NORM. In such cases, their concentration at significant levels from the perspective of environmental and occupational radiation protection may occur. This study aims to evaluate the presence of the natural radioactive {sup 238}U and {sup 232}Th series in the treatment of city water elements Pocos de Caldas - MG (water, materials and waste). The study can serve as an indication of the necessity of a more detailed review in the locally and in the country on this radiological issue. (author)

    This study was performed to evaluate the cosmetic outcome of conservative treatment for early breast cancer and to analyze the factors influencing cosmetic outcome. From February 1992 through January 1997, 120 patients with early breast cancer were treated with conservative surgery and postoperative radiotherapy. The types of conservative surgery were quadrantectomy and axillary node dissection for 108 patients (90%) and lumpectomy or excisional biopsy for 10 patients (8.3%). Forty six patients (38%) received adjuvant chemotherapy (CMF or CAF). Cosmetic result evaluation was carried out between 16 and 74 months (median, 33 months) after surgery. The cosmetic results were classified into four categories, i.e., excellent, good, fair, and poor. The appearances of the patients' breasts were also analyzed for symmetry using the differences in distances from the stemal notch to right and left nipples. A logistic regression analysis was performed to identify independent variables influencing the cosmetic outcome. Cosmetic score was excellent or good in 76% (91/120), fair in 19% (23/120) and poor in 5% (6/ 120) of the patients. Univariate analysis showed that tumor size (T1 versus T2) (p=0.04), axillary node status (NO versus N1) (p=0.0002), extent of surgery (quadrantectomy versus lumpectomy or excisional biopsy) (p=0.02), axillary node irradiation (p=0.0005) and chemotherapy (p=0,0001) affected cosmetic score. Multivariate analysis revealed that extent of surgery (p=0.04) and chemotherapy (p=0.0002) were significant factors. For breast symmetry, univariate analysis confirmed exactly the same factors as above. Multivariate analysis revealed that tumor size (p=0.003) and lymph node status (p=0.007) affected breast symmetry. Conservative surgery and postoperative radiotherapy resulted in excellent or good cosmetic outcome in a large portion of the patients. Better cosmetic results were achieved generally in the group of patients with smaller tumor size, without axillary

    Ring specimens of 5-mm width cut from Zircaloy-2 cladding of reactor operated fuel elements that had experienced 5000 to 15,000 MWD/T of fuel burnup were subjected to ring tensile testing. The true stress-true strain data points up to the onset of necking from the individual load-elongation curves of these specimens were used as input data in Voce's equation. The results reveal that the uniform elongation (UE) values generated using Voce's equation were within (UE-2)% of the experimental percent uniform elongation (UE%). The corresponding ultimate tensile strength values were within ±1%. The uncertainty inherently associated in the determination of gauge length introduces extraneous deformation in the rings tested. Previous results had shown that a 14% increase in cladding diameter caused the gauge length to increase by 40%. To simulate the contribution of extraneous deformation due to an increase in cladding diameter, an analysis of the variation of the tensile parameters (uniform elongation and ultimate tensile strength) due to increase in the gauge length in the range of 10 to 40% was carried out. The results are discussed

    Urethral carcinoma in women is uncommon. This study was undertaken to evaluate the role of radiotherapy in the treatment of these tumors. The hospital records of 34 women with primary urethral carcinoma were retrospectively reviewed. There were 15 squamous cell carcinomas, 13 transitional cell carcinomas, and six adenocarcinomas. The primary tumor was >4 cm in size in eight patients, involved the proximal urethra in 19 and extended to adjacent organs in 22. Inguinal or iliac lymphadenopathy was present in nine patients. There were eight TNM stage I/II tumors, 11 stage III tumors and 15 stage IV tumors. Radiotherapy was administered only to the primary tumor in 15 patients, and to the primary tumor and regional lymph nodes in the remaining 19 patients. Brachytherapy with or without external radiation was used to treat the primary tumor in 20 patients. Tumor recurred in 21 patients. The 7-year actuarial overall and cause-specific survivals were 41 and 45%, respectively. Large primary tumor bulk and treatment with external beam radiation alone (no brachytherapy) were independent adverse prognostic factors for local tumor recurrence. Brachytherapy reduced the risk of local recurrence by a factor of 4.2. The beneficial effect of brachytherapy was most prominently seen in patients with bulky primary disease. Large tumor size was the only independent adverse predictor of overall disease recurrence and death from cancer. Radiotherapy is an effective treatment for carcinoma of the female urethra and preserves normal anatomy and function. Brachytherapy improves local tumor control, possibly as a result of the higher radiation dose that can safely be delivered. (author)

    The authors are investigating patients undergoing extracorporeal shock wave lithotripsy (ESWL) to determine if more rigorous assessment of residual calculi by conventional (CR) and digital (DR) renal tomography provides a truer evaluation of the treatment's effectiveness. One hundred sequential patients are being imaged before and after ESWL by KUB, CR, and DR. Examinations are independently reviewed by three radiologists. Differences are elicited by calculating sensitivity, specificity, and by receiver operating characteristic analysis. Results in 35 patients show improved detection of calculi by tomography versus KUB, with greater differences noted in posttreatment studies when calculi are generally smaller. DR appears to be somewhat more effective than CR

    The authors evaluated the results of treating hyperthyroidism with 131 I. Patient selection for tre treatment is based on clinical features and laboratory test results such as thyroid uptake, scintigraphy and RIA determinations of thyroid hormones. The average dose is 6.2±1.1 m Ci (that is 233.1±40.7 MBq). The average number of doses is 1.3 for one patient. The results are as follows: - Euthyroid status after 4 years follow-up from the 1 31 I dose administration: 72.3 - Persistent or recurrent hyperthyroidism: 20 %. - Hypothyroid complication appears 6 years after the administration of 1 31 I dose: 14 %. So the cumulative hypothyroid rate is: 2.3 % per year. - Serious complications were not observed in any patient. Hyperthyroidism is a common health problem in Vietnam (1). In the past, only antithyroid drugs and surgery were used. 131 I was first introduced to Vietnam in the Nuclear Medicine Department in Bach Mai in 1971 and thereafter widely applied in the country.

    2001-01-01

    Bechtel National, Inc. (BNI) provided a forecast of the radioactive, dangerous liquid effluents expected to be generated by the Waste Treatment Plant (WTP). The forecast represents the liquid effluents generated from the processing of 25 distinct batches of tank waste through the WTP. The WTP liquid effluents will be stored, treated, and disposed of in the Liquid Effluent Retention Facility (LERF) and the Effluent Treatment Facility (ETF). Fluor Hanford, Inc. (FH) evaluated the treatability of the WTP liquid effluents in the LERFIETF. The evaluation was conducted by comparing the forecast to the LERFIETF treatability envelope, which provides information on the items that determine if a liquid effluent is acceptable for receipt and treatment at the LERFIETF. The WTP liquid effluent forecast is outside the current LERFlETF treatability envelope. There are several concerns that must be addressed before the WTP liquid effluents can be accepted at the LERFIETF

We evaluated the efficacy and safety of a partially completed chemoradiation regimen prescribed for locally advanced carcinoma of the cervix. Methods: Medical records of 156 patients with locally advanced cervical cancer stage IIB–IVA who received chemoradiation with cisplatin (40 mg/m2 and 5-fluorouracil (500 mg/m2 from October 2006 to October 2008 were collected. The treatment protocol called for two cycles of chemotherapy. External beam radiation therapy was administered using a 10-MeV electron beam. Local control, disease free survival, overall survival, and toxicities were evaluated. Results: With a median follow-up of 37.5 months, 89 patients (57% completed the planned protocol. Sixty seven patients (43% completed fewer than two cycles. The 3-year local control rate was significantly better in the patient group that completed the prescribed plan (92.1% compared to 80.6%; P = 0.033. No statistical significance was observed between the groups that completed or did not complete the two cycle protocol with regard to disease free survival (80.9% and 73.2%, respectively; P = 0.250, overall survival (84.3% and 79.1%; P = 0.405, and progression survival (3.4% and 3.0%; P = 0.892. Differences in acute hematologic toxicity and subcutaneous toxicity were observed between the two groups. Conclusions: Completion of two cycles of 5-fluorouracil and cisplatin with radiotherapy was effective, safe, and responsible for better local control

    This report presents the second phase of a study on thermal treatment technologies. The study consists of a systematic assessment of nineteen thermal treatment alternatives for the contact-handled mixed low-level waste (MLLW) currently stored in the US Department of Energy complex. The treatment alternatives consist of widely varying technologies for safely destroying the hazardous organic components, reducing the volume, and preparing for final disposal of the MLLW. The alternatives considered in Phase 2 were innovative thermal treatments with nine types of primary processing units. Other variations in the study examined the effect of combustion gas, air pollution control system design, and stabilization technology for the treatment residues. The Phase 1 study examined ten initial thermal treatment alternatives. The Phase 2 systems were evaluated in essentially the same manner as the Phase 1 systems. The alternatives evaluated were: rotary kiln, slagging kiln, plasma furnace, plasma gasification, molten salt oxidation, molten metal waste destruction, steam gasification, Joule-heated vitrification, thermal desorption and mediated electrochemical oxidation, and thermal desorption and supercritical water oxidation. The quantities, and physical and chemical compositions, of the input waste used in the Phase 2 systems differ from those in the Phase 1 systems, which were based on a preliminary waste input database developed at the onset of the Integrated Thermal Treatment System study. The inventory database used in the Phase 2 study incorporates the latest US Department of Energy information. All systems, both primary treatment systems and subsystem inputs, have now been evaluated using the same waste input (2,927 lb/hr). 28 refs., 88 figs., 41 tabs.

    Over the past decade, the EVAR (Endovascular aortic aneurysm repair) became an accepted treatment of abdominal aortic aneurysms (AAA) as compared with the radical open surgical treatment. Due to the latest generation of stents, 60% of infra renal AAA can be treated by the endovascular method or even percutaneously, without any surgical procedure, and only under the local anesthesia. We retrospectively evaluated the findings of patients following elective EVAR who underwent CTA examination immediately after the procedure and three months after the procedure, for the period from June 2009 to February 2010 (9 months).

    Abdominal bloating is commonly reported by men and women of all ages. Bloating occurs in nearly all patients with irritable bowel syndrome, and it also occurs in patients with other functional and organic disorders. Bloating is frequently disturbing to patients and frustrating to clinicians, as effective treatments are limited and are not universally successful. Although the terms bloating and abdominal distention are often used interchangeably, these symptoms likely involve different pathophysiologic processes, both of which are still not completely understood. The goal of this paper is to review the pathophysiology, evaluation, and treatment of bloating and abdominal distention. PMID:22298969

    Full Text Available The aim of the present study is to establish the results using the scores obtained from the methodology that was applied for assessing the stability after 2 years post orthodontic treatment and stability in a sample of 69 individuals. After applying PAR index to the collected group of patients, a series of scores were obtained, which were then needed to be evaluated further to establish the results. The scores were evaluated using the nomogram. A comparison was done between the post treatment and the 2 years post treatment PAR weighting scores to determine if the results were stable after orthodontic treatment. The majority of the orthodontic patients were treated to a good standard and that the results appeared to be stable.

    An aspect of the Los Alamos Scientific Laboratory's nuclear waste management R and D programs has been to develop an evaluation procedure for radioactive waste treatment processes. This report describes the process evaluation method. Process worth is expressed as a numerical index called the Figure-of-Merit (FOM), which is computed using a hierarchial, linear, additive, scoring model with constant criteria weights and nonlinear value functions. A numerical example is used to demonstrate the procedure and to point out some of its strengths and weaknesses. Potential modifications and extensions are discussed, and an extensive reference list is included

  7. Evaluation of treatment effects by ranking

    In crop experiments measurements are often made by a judge evaluating the crops' conditions after treatment. In the present paper an analysis is proposed for experiments where plots of crops treated differently are mutually ranked. In the experimental layout the crops are treated on consecutive...... plots usually placed side by side in one or more rows. In the proposed method a judge ranks several neighbouring plots, say three, by ranking them from best to worst. For the next observation the judge moves on by no more than two plots, such that up to two plots will be re-evaluated again...... in a comparison with the new plot(s). Data from studies using this set-up were analysed by a Thurstonian random utility model, which assumed that the judge's rankings were obtained by comparing latent continuous utilities or treatment effects. For the latent utilities a variance component model was considered...

    Hospitalized patients are at increased risk for candidemia and invasive candidiasis (C/IC). Improved therapeutic regimens with enhanced clinical and pharmacoeconomic outcomes utilizing existing antifungal agents are still needed. An open-label, non-comparative study evaluated an intravenous (i.v.) to oral step-down strategy. Patients with C/IC were treated with i.v. anidulafungin and after 5 days of i.v. therapy had the option to step-down to oral azole therapy (fluconazole or voriconazole) if they met prespecified criteria. The primary endpoint was the global response rate (clinical + microbiological) at end of treatment (EOT) in the modified intent-to-treat (MITT) population (at least one dose of anidulafungin plus positive Candida within 96 hours of study entry). Secondary endpoints included efficacy at other time points and in predefined patient subpopulations. Patients who stepped down early (≤ 7 days' anidulafungin) were identified as the "early switch" subpopulation. In total, 282 patients were enrolled, of whom 250 were included in the MITT population. The MITT global response rate at EOT was 83.7% (95% confidence interval, 78.7-88.8). Global response rates at all time points were generally similar in the early switch subpopulation compared with the MITT population. Global response rates were also similar across multiple Candida species, including C. albicans, C. glabrata, and C. parapsilosis. The most common treatment-related adverse events were nausea and vomiting (four patients each). A short course of i.v. anidulafungin, followed by early step-down to oral azole therapy, is an effective and well-tolerated approach for the treatment of C/IC. ClinicalTrials.gov: NCT00496197.

    We evaluated immediate and long-term results of percutaneous transluminal angioplasty (PTA) and stent placement to treat stenotic and occluded arteries in patients with chronic mesenteric ischemia. Fourteen patients were treated by 3 exclusive celiac artery (CA) PTAs (2 stentings), 3 cases with both Superior Mesenteric Artery (SMA) and CA angioplasties, and 8 exclusive SMA angioplasties (3 stentings). Eleven patients had atheromatous stenoses with one case of an early onset atheroma in an HIV patient with antiphospholipid syndrome. The other etiologies of mesenteric arterial lesions were Takayashu arteritis (2 cases) and a postradiation stenoses (1 case). Technical success was achieved in all cases. Two major complications were observed: one hematoma and one false aneurysm occurring at the brachial puncture site (14.3%). An immediate clinical success was obtained in all patients. During a follow-up of 1-83 months (mean: 29 months), 11 patients were symptom free; 3 patients had recurrent pain; in one patient with inflammatory syndrome, pain relief was obtained with medical treatment; in 2 patients abdominal pain was due to restenosis 36 and 6 months after PTA, respectively. Restenosis was treated by PTA (postirradiation stenosis), and by surgical bypass (atheromatous stenosis). Percutaneous endovascular techniques are safe and accurate. They are an alternative to surgery in patients with chronic mesenteric ischemia due to short and proximal occlusive lesions of SMA and CA

    Objective To examine the characteristics of women seeking infertility evaluation and treatment. Design Cross-sectional survey based on in-person interviews, followed by two-step hurdle analysis. Participants 4,558 married or cohabitating women ages 25–44 Setting U.S. household population of women based on the 2006–2010 National Survey of Family Growth Intervention None Main Outcome Measure(s) Likelihood of seeking preliminary infertility evaluation. Likelihood of seeking infertility treatment once evaluated. Treatment type provided. Results 623 women (13.7%) reported seeking infertility evaluation, of which 328 reported undergoing subsequent infertility treatment. Age at marriage, marital status, education, health insurance status, race/ethnicity, and religion were associated with the likelihood of seeking infertility evaluation. For example, the predicted probability that a non-White woman who married at 25 will seek evaluation was 12%. This probability increased to 34% for White women with a graduate degree who married at age 30. Among women who are evaluated, income, employment status, and ethnicity correlated strongly with the likelihood of seeking infertility treatment. Infertility drug therapy was the most frequent treatment used. Reproductive surgery and in vitro fertilization (IVF) were used the least. Conclusions The use of infertility services is not random and understanding the socio-demographic factors correlated with use may assist new couples with family planning. Roughly 50% of the women evaluated for infertility progressed to treatment, and only a small proportion were treated with more advanced assisted reproductive technologies (ARTs) such as IVF therapy. Future research aimed at improving access to effective healthcare treatments within the boundaries of affordability is warranted. PMID:23849845

    Full Text Available Purpose: Accurate prostate low dose-rate brachytherapy treatment plan evaluation is important for future care decisions. Presently, an evaluation is based on dosimetric quantifiers for the tumor and organs at risk. However, these do not account for effects of varying dose-rate, tumor repopulation and other biological effects. In this work, incorporation of the biological response is used to obtain more clinically relevant treatment plan evaluation.Material and methods: Eleven patients were evaluated. Each patient received a 145 Gy implant. Iodine-125 seeds were used and the treatment plans were created on the Prowess system. Based on CT images the post-implant plan was created. In the post-plan, the tumor, urethra, bladder and rectum were contoured. The biologically effective dose was used to determine the tumor control probability and the normal tissue complication probabilities for the urethra, bladder, rectum and surrounding tissue. Results: The average tumor control probability and complication probabilities for the urethra, bladder, rectum and surrounding tissue were 99%, 29%, 0%, 12% and 6%, respectively. These measures provide a simpler means for evaluation and since they include radiobiological factors, they provide more reliable estimation of the treatment outcome. Conclusions: The goal of this work was to create more clinically relevant prostate seed-implant evaluation by incorporating radiobiological measures. This resulted in a simpler descriptor of treatment plan quality and was consistent with patient outcomes.

    To evaluate a treatment process redesign programme implementing evidence-based treatment as part of a total quality management in a Dutch addiction treatment centre. Quality management was monitored over a period of more than 10 years in an addiction treatment centre with 550 professionals. Changes are evaluated, comparing the scores on the nine criteria of the European Foundation for Quality Management (EFQM) Excellence Model before and after a major redesign of treatment processes and ISO certification. In the course of 10 years, most intake, care, and cure processes were reorganized, the support processes were restructured and ISO certified, 29 evidence-based treatment protocols were developed and implemented, and patient follow-up measuring was established to make clinical outcomes transparent. Comparing the situation before and after the changes shows that the client satisfaction scores are stable, that the evaluation by personnel and society is inconsistent, and that clinical, production, and financial outcomes are positive. The overall EFQM assessment by external assessors in 2004 shows much higher scores on the nine criteria than the assessment in 1994. Evidence-based treatment can successfully be implemented in addiction treatment centres through treatment process redesign as part of a total quality management strategy, but not all results are positive.

    The goal of this work is to evaluate the effectiveness of Plan‐Checker Tool (PCT) which was created to improve first‐time plan quality, reduce patient delays, increase the efficiency of our electronic workflow, and standardize and automate the physics plan review in the treatment planning system (TPS). PCT uses an application programming interface to check and compare data from the TPS and treatment management system (TMS). PCT includes a comprehensive checklist of automated and manual checks that are documented when performed by the user as part of a plan readiness check for treatment. Prior to and during PCT development, errors identified during the physics review and causes of patient treatment start delays were tracked to prioritize which checks should be automated. Nineteen of 33 checklist items were automated, with data extracted with PCT. There was a 60% reduction in the number of patient delays in the six months after PCT release. PCT was successfully implemented for use on all external beam treatment plans in our clinic. While the number of errors found during the physics check did not decrease, automation of checks increased visibility of errors during the physics check, which led to decreased patient delays. The methods used here can be applied to any TMS and TPS that allows queries of the database. PACS number(s): 87.55.‐x, 87.55.N‐, 87.55.Qr, 87.55.tm, 89.20.Bb PMID:27929478

    An integrated systems engineering approach is used for uniform comparison of widely varying thermal treatment technologies proposed for management of contact-handled mixed low-level waste (MLLW) currently stored in the US Department of Energy complex. Ten different systems encompassing several incineration design options are studied. All subsystems, including facilities, equipment, and methods needed for integration of each of the ten systems are identified. Typical subsystems needed for complete treatment of MLLW are incoming waste receiving and preparation (characterization, sorting, sizing, and separation), thermal treatment, air pollution control, primary and secondary stabilization, metal decontamination, metal melting, mercury recovery, lead recovery, and special waste and aqueous waste treatment. The evaluation is performed by developing a preconceptual design package and planning life-cycle cost (PLCC) estimates for each system. As part of the preconceptual design process, functional and operational requirements, flow sheets and mass balances, and conceptual equipment layouts are developed for each system. The PLCC components estimated are technology development, production facility construction, pre-operation, operation and maintenance, and decontamination and decommissioning. Preconceptual design data and other technology information gathered during the study are examined and areas requiring further development, testing, and evaluation are identified and recommended. Using a qualitative method, each of the ten systems are ranked

    Objective: To evaluate the diagnostic and the predictive value of Arizona Sexual Experience Scale among primary infertile couples regarding sexual dysfunction. Methods: The cross-sectional and prospective pre, post study comprising primary infertile patients was carried out at Bulent Ecevit University Hospital, Zonguldak, Turkey. Fifty consecutive primary infertile couples not treated previously were investigated between 2003 and 2007 for the presence of sexual dysfunction by a psychiatrist. Arizona Sexual Experience Scale scoring was self-administered to determine sexual dysfunction among couples before treatment and also 3 months after the initiation of the treatment. Results: Pretreatment mean values of the index parametres in both women and men were significantly increased after treatment. Statistically significant positive correlation was observed between pre- and post-treatment total scores in both women (r=0.83; p 14 (Sensitivity: 57%; Specificity: 90%) and >13 (Sensitivity: 83%; Specificity: 93%), respectively. Pre- and post-treatment scores in men were >10 (Sensitivity: 65%; Specificity: 61%), >11 (Sensitivity: 83%; Specificity: 62%), respectively. Binary logistic regression analyses revealed women's pre-treatment and post-treatment scores as a significant factor for prediction of sexual dysfunction independent of sociodemographic factors (p=0.001 and p=0.001, respectively). Conclusion: Evaluation and treatment of infertility is an important risk factor for sexual dysfunction. Pre- and post-treatment Arizona Sexual Experience Scale score could be used as a screening test for sexual dysfunction and might be used to decide pre/post-treatment consultation of couples with a specialist.

    There have been several diagnostic labels for persistent, excessive sexual behaviors, often referred in the popular media as sex addiction. Two related diagnoses, Internet addictive disorder and hypersexual disorder, were considered for, but not included in the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders. However, most clinicians, even those trained in sexual disorders or addiction medicine, have little to no training in treating sexual compulsivity and cybersex addiction. The authors present the historical context, proposed diagnostic criteria, evaluation protocols, comorbid disorders, speculations about the neuroscience, and treatment recommendations.

    Important considerations for constipation include: 1. Initial evaluation should evaluate for fecal incontinence, fecal impaction, medication side effects, concerning symptoms, underlying medical or metabolic issues and irritable bowel syndrome. 2. History and examination should be used to determine if a defecatory disorder is most likely. a. If defecatory disorder is likely, testing with balloon expulsion or anal manometry can be considered and, if confirmed, treatment with biofeedback (if testing not available, it is reasonable to trial fiber and laxatives because many patients have a mixed disorder). b. If it is unlikely, proceed with trial of fiber and/or osmotic laxatives. 3. If continued symptoms, consider trial of newer agent (lubiprostone or linaclotide). 4. If ineffective, consider testing for colon transit time and referral to gastroenterology. Copyright © 2014 Elsevier Inc. All rights reserved.

    2009-09-01

    The work aimed at analyzing results of kinesitherapeutic procedures in patients with cervical vertigo as well as evaluating a mobility range of the cervical spine. The study was conducted on 23 people, including 17 women and 6 men suffering from cervical vertigo, at the age of 23-73 (the average age of 49.5). All the patients had an individually selected cycle of kinesitherapeutic exercises through the period of 2 months. The objective efficiency evaluation of the applied therapy was made on the grounds of the videonystagmographic examination (VNG). Additionally, the range of active mobility of the cervical spine was analyzed and the evaluation of vertigo according to Silvoniemi's criteria was performed. After a 2-month therapy 4 patients (17.4%) out of the examined material showed a total lack of vertigo, 15 patients (65.2%) demonstrated a meaningful decrease in the vertigo intensity, also in the frequency of their occurrence in 14 cases (60.8%). Only 3 patients did not show any decrease in vertigo whereas in 1 patient a slight increase in the intensity was indicated. On the basis of a subjective evaluation of the vertigo increase according to the 5-stage Silvoniemi's scale it was proved that a mean point assessment claimed by the patients at the beginning of the therapy amounts to 3.0 points whereas after the therapy it was as follows: 1.43 pt after 2 weeks, 1.17 pt after 1 month and 1.13 pt after 2 months of kinesitherapy. It is extremely difficult to fully eliminate the symptoms of cervical vertigo (in the studied material in 4 cases--17.3%) because the causes of their occurrence, which are connected with excessive tension and degeneration in the cervical spine, cannot usually be eradicated. Additionally, as a diagnostic means, the videonystagmographic examination (VNG) accompanied by the positioning tests and the cervical rotation test facilitates precise and objective monitoring of the progress in treatment and rehabilitation of vertigo.

    Brůha, Radan; Petrtýl, Jaromír

    Liver cirrhosis is a serious disease shortening the life expectancy. Unavoidable consequence of cirrhosis is portal hypertension, which usually limits the prognosis by its complications. Portal hypertension is a prognostic factor for cirrhosis decompensation, variceal bleeding and even the mortality in cirrhotic patients. In the evaluation of portal hypertension hepatic venous pressure gradient (HVPG) measurement is used.Measurement of HVPG is used in clinical praxis in these situations: diagnosis of portal hypertension, evaluation of prognosis of patients with cirrhosis, monitoring the treatment efficacy in the prevention of variceal bleeding, management of acute variceal bleeding. Decrease of HVPG below 12 mmHg or at least for more than 20% of initial value in the treatment by beta-blockers is associated with the lower risk of bleeding from varices or other complications. HVPG above 20 mm Hg is associated with the high risk of early rebleeding from varices and can discriminate those patients profiting from early TIPS.HVPG measurement is an invasive, but simple, reproducible and safe catheterization technique with minimal complication rate. The most frequent complication could be incorrect assessment of obtained values. HVPG measurement should be a routine technique in centers specialized to liver diseases.

    Full Text Available Decision makers for waste management are confronted with the problem of selecting the most economic, environmental, and socially acceptable waste treatment process. This paper elucidates evaluation methods for waste treatment processes for the comparison of ecological and economic aspects such as material flow analysis, statistical entropy analysis, energetic and exergetic assessment, cumulative energy demand, and life cycle assessment. The work is based on the VDI guideline 3925. A comparison of two thermal waste treatment plants with different process designs and energy recovery systems was performed with the described evaluation methods. The results are mainly influenced by the type of energy recovery, where the waste-to-energy plant providing district heat and process steam emerged to be beneficial in most aspects. Material recovery options from waste incineration were evaluated according to sustainability targets, such as saving of resources and environmental protection.

  10. INTEGRATED WATER TREATMENT SYSTEM PERFORMANCE EVALUATION

    International Nuclear Information System (INIS)

    Sexton, R.A.; Meeuwsen, W.E.

    2009-01-01

    This document describes the results of an evaluation of the current Integrated Water Treatment System (IWTS) operation against design performance and a determination of short term and long term actions recommended to sustain IWTS performance. The KW IWTS was designed to treat basin water and maintain basin clarity during fuel retrieval, washing, and packaging activities in the KW Basin. The original design was based on a mission that was limited to handling of KW Basin fuel. The use of the IWTS was extended by the decision to transfer KE fuel to KW to be cleaned and packaged using KW systems. The use was further extended for the packaging of two more Multi-Canister Overpacks (MCOs) containing legacy fuel and scrap. Planning is now in place to clean and package Knock Out Pot (KOP) Material in MCOs using these same systems. Some washing of KOP material in the Primary Cleaning Machine (PCM) is currently being done to remove material that is too small or too large to be included in the KOP Material stream. These plans will require that the IWTS remain operational through a campaign of as many as 30 additional MCOs, and has an estimated completion date in 2012. Recent operation of the IWTS during washing of canisters of KOP Material has been impacted by low pressure readings at the inlet of the P4 Booster Pump. The system provides a low pressure alarm at 10 psig, and low-low pressure interlock at 5 psig. The response to these low readings has been to lower total system flow to between 301 and 315 gpm. In addition, the IWTS operator has been required to operate the system in manual mode and make frequent adjustments to the P4 booster pump speed during PCM washes. The preferred mode of operation is to establish a setpoint of 317 gpm for the P4 pump speed and run IWTS in semi-automatic mode. Based on hydraulic modeling compared to field data presented in this report, the low P4 inlet pressure is attributed to restrictions in the 2-inch KOP inlet hose and in the KOP itself

    PurposeCystic echinococcosis (CE) in the spleen is a rare disease even in endemic regions. The aim of this study was to examine the efficacy of percutaneous treatment for splenic CE.Materials and MethodsTwelve patients (four men, eight women) with splenic CE were included in this study. For percutaneous treatment, CE1 and CE3A splenic hydatid cysts were treated with either the PAIR (puncture, aspiration, injection, respiration) technique or the catheterization technique.ResultsEight of the hydatid cysts were treated with the PAIR technique and four were treated with catheterization. The volume of all cysts decreased significantly during the follow-up period. No complication occurred in seven of 12 patients. Abscess developed in four patients. Two patients underwent splenectomy due to cavity infection developed after percutaneous treatment, while the spleen was preserved in 10 of 12 patients. Total hospital stay was between 1 and 18 days. Hospital stay was longer and the rate of infection was higher in the catheterization group. Follow-up period was 5–117 months (mean, 44.8 months), with no recurrence observed.ConclusionThe advantages of the percutaneous treatment are its minimal invasive nature, short hospitalization duration, and its ability to preserve splenic tissue and function. As the catheterization technique is associated with higher abscess risk, we suggest that the PAIR procedure should be the first percutaneous treatment option for splenic CE.

    Full Text Available For evaluating the work results of tillage operations today only inaccurate parameters are available which cannot be readily measured. Thus, evaluating and comparing the work results of machines and developing suitable sensors are difficult. At the Technical University of Dresden, till 1990, research projects for determining aggregate size composition of soil have been done. Based on this work, this study will show suggestions for measuring, displaying and evaluation of soil crushing results depending on tillage work conditions.

    Avascular necrosis (AVN) after internal fixation of intracapsular hip fractures is a progressive multifactorial disease that ultimately results in local ischemia with ensuing osteocyte necrosis and structural compromise. This disease can cause significant clinical morbidity and affects patients of any age, including young and active patients. Effective treatment of this condition among young adults is challenging due to their high functional demands. The aim of managing AVN is to relieve pain, preserve range of movement and improve function. Treatment methods vary depending on the stage of the disease and can be broadly categorised into two options, hip preserving surgery and hip arthroplasty. Although, hip preserving techniques are attractive in the young adult, they may alter the morphology of the proximal femur and make subsequent arthroplasty more challenging. Conversely, arthroplasty in the young adult may require repeat revision procedures throughout the patient's life. Current evidence suggests that modifications of prevailing treatments, in addition to new technologies, have led to the development of management strategies that may be able to alter the course of femoral head osteonecrosis. This review aims to summarise the options available for treatment of AVN in the young adult and review the clinical results. Copyright © 2014 Elsevier Ltd. All rights reserved.

    Full Text Available Background: Pirfenidone was approved by the European Medicines Agency and introduced in most European countries in 2011 for treatment of idiopathic pulmonary fibrosis (IPF. Objective: To describe the national Danish experiences of pirfenidone treatment for IPF during 30 months with respect to target population, safety, adherence to the treatment and effect analysis in a well-characterised IPF population in a real-life setting. Methods: Retrospective data collection from medical records of all patients in Denmark with IPF from 2011 to 2014. Data included baseline demographics, high-resolution computed tomography (HRCT, histopathology, forced vital capacity (FVC and 6-min walk test (6MWT. Longitudinal data on FVC, walk test, adherence to the treatment and vital status were also collected. Results: Pirfenidone treatment was initiated in 113 patients. Mean age was 69.6±8.1 years (±SD, and 71% were male. Definite IPF diagnosis required thoracoscopic lung biopsy in 45 patients (39.8%. The remaining 68 cases had a definite (64 patients or possible usual interstitial pneumonia (four patients pattern on HRCT. Patients were followed for 0.1–33.8 months (median 9.4 months. Fifty-one patients (45.2% needed dose adjustment, 18 (16% patients discontinued therapy and 13 patients (11.5% died. The annual mean decline in FVC was 164 ml (SE 33.2. The decline in 6MWT was 18.2 m (SE 11.2. Nausea (44.2%, fatigue (38.9% and skin reactions (32.7% were frequent adverse events. Conclusion: Patients with IPF treated with pirfenidone experienced tolerable adverse events. Patients were maintained on treatment due to a careful follow-up and dose adjustment programme. The annual decline in physiological parameters and mortality rate was comparable to previous randomised controlled trials.

    In order to facilitate scale-up of antiretroviral therapy (ART) in Malawi, innovative and pragmatic models have been developed to optimize the efficiency of HIV service delivery. In particular, three models of differentiated care have emerged for stable patients: adjusted appointment spacing through multi-month scripting (MMS); fast-track drug refills (FTRs) on alternating visits; and community ART groups (CAGs) where group members rotate in collecting medications at the facility for all members. This study aimed to assess the extent to which ART patients in Malawi are differentiated based on clinical stability and describe the characteristics and costs associated with the models of differentiated care offered. A mixed methods process evaluation was conducted from 30 purposefully selected ART facilities. Cross-sectional data for this evaluation was collected between February and May 2016. The following forms of data collection are reported here: structured surveys with 136 health care workers; reviews of 75,364 patient clinical records; 714 observations of visit time and flow; and 30 questionnaires on facility characteristics. Among ART patients, 77.5% (95% confidence interval [CI] 74.1-80.6) were eligible for differentiated models of care based on criteria for clinical stability from national guidelines. Across all facilities, 69% of patients were receiving MMS. In facilities offering FTRs and CAGs, 67% and 6% of patients were enrolled in the models, respectively. However, eligibility criteria were used inconsistently: 72.9% (95% CI 66.3-78.6) of eligible patients and 42.3% (95% CI 33.1-52.0) ineligible patients received MMS. Results indicated that patient travel and time costs were reduced by 67%, and the unit costs of ART service delivery through the MMS, FTR and CAG models were similar, representing a reduction of approximately 10% in the annual unit cost of providing care to stable patients that receive no model. MMS is being implemented nationally and has

    Purpose: Nasopharyngeal carcinoma (NPC) has a bimodal age distribution. In contrast to the adult variant, little is known about the juvenile form. This study examined the treatment results between adult (aNPC) and juvenile NPC (jNPC) patients for future treatment considerations in jNPC. Methods and Materials: The jNPC population included 53 patients treated at two institutions between 1972 and 2004. The aNPC population included 84 patients treated at one institution. The patients had received a median dose of 66 Gy of external beam radiotherapy and 72% underwent chemotherapy. The mean follow-up for surviving patients was 12.6 years for jNPC and 6.6 years for aNPC. Results: The jNPC patients presented with more advance stages than did the aNPC patients (92% vs. 67% Stage III-IV, p = .006). However, jNPC patients had significantly better overall survival (OS) than did aNPC patients. The 5-year OS rate was 71% for jNPC and 58% for aNPC (p = .03). The jNPC group also demonstrated a trend for greater relapse-free survival than the aNPC group (5-year relapse-free survival rate, 69% vs. 49%; p = .056). The pattern of failure analysis revealed that the jNPC patients had greater locoregional control and freedom from metastasis but the differences were not statistically significant. Univariate analysis for OS revealed that age group, nodal classification, and chemotherapy use were significant prognostic factors. Age group remained significant for OS on multivariate analysis, after adjusting for N classification and treatment. Conclusion: Despite more advance stage at presentation, jNPC patients had better survival than did aNPC patients. Future treatment strategies should take into consideration the long-term complications in these young patients.

    This report documents Fiscal Year 1992 technical progress on the Sludge Treatment Evaluation Task, which is being conducted by Pacific Northwest Laboratory. The objective of this task is to develop a capability to predict the performance of pretreatment processes for mixed radioactive and hazardous waste stored at Hanford and other US Department of Energy (DOE) sites. Significant cost savings can be achieved if radionuclides and other undesirable constituents can be effectively separated from the bulk waste prior to final treatment and disposal. This work is initially focused on chemical equilibrium prediction of water washing and acid or base dissolution of Hanford single-shell tank (SST) sludges, but may also be applied to other steps in pretreatment processes or to other wastes. Although SST wastes contain many chemical species, there are relatively few constituents -- Na, Al, NO 3 , NO 2 , PO 4 , SO 4 , and F -- contained in the majority of the waste. These constituents comprise 86% and 74% of samples from B-110 and U-110 SSTS, respectively. The major radionuclides of interest (Cs, Sr, Tc, U) are present in the sludge in small molal quantities. For these constituents, and other important components that are present in small molal quantities, the specific ion-interaction terms used in the Pitzer or NRTL equations may be assumed to be zero for a first approximation. Model development can also be accelerated by considering only the acid or base conditions that apply for the key pretreatment steps. This significantly reduces the number of chemical species and chemical reactions that need to be considered. Therefore, significant progress can be made by developing all the specific ion interactions for a base model and an acid dissolution model

    Introduction: radioiodine ( 131 I) is an effective and inexpensive alternative to surgery in the treatment of thyroid hyper function. The debate today concerns the maximum and minimum ablative doses, and factors leading to hypothyroidism. Patients and method: 1035 hyperthyroid patients treated with weight-adjusted ablative doses of 131 I were retrospectively assessed for treatment outcome or correlated with sex, age, underlying pathology, and administrated dose of 131 I . Results: Thyroid hyper function was more common in women. The greatest proportions of patients were in the 31-40 years age group and the smallest proportion over -70. The commonest underlying pathology was Grave's disease. Men had a lower response rate to 131 I therapy, with 2.4-fold greater probability of persistent hyperthyroidism (P 131 I hypothyroidism decreased with increasing age (P 131 I therapy was seen in patients with toxic adenoma, (P=0.0001). The incidence of hypothyroidism did not show a positive correction with increased administered dose of 131 I (P 131 I was effective in reducing thyroid nodule size. There were 18 cases of temporary hyperthyroidism, all of which recovered to euthyroid status within 12 months. Conclusion: one dose of radioiodine was effective in treatment of hyperthyroid patients in 91.2 % of cases. Age, sex and underlying pathology were determining factors. In most cases the average time to hypothyroidism was reasonably short, obviating the need for long time follow up in these patients

    During an investigation period starting early in 1982 and ending in the middle of 1985 a total of 360 patients were treated with iodine-131 for hyperthyroidism of different origins. The case reports of 337 of these patients were reviewed for the purposes of this study. The patients were divided into three groups. In this cohort, the healing rates achieved with one single treatment were 84.4% for autonomic adenomas, 50.8% for hyperthyroidism of other than immunologic origins and 22.7% for Basedow's disease. After a series of up to four treatments the healing rates were seen to be increased to 93% for autonomous adenomas, 84% for nonimmunogenic hyperthyroidism and 80% for Basedow's disease. The results thus achieved appeared to be unrelated to the patients' sex or previous surgical interventions for disorders of the thyroid. The findings show that therapeutic regimes calculated individually on the basis of a formula should be approached with some caution. Thus, doses lower than 100 Gy are hardly advisable for patients showing diffuse hyperthyroidism. It would also appear wise in autonomous adenomas to reduce the dose from 400 to 200 Gy. Likewise, the use of doses above 15 mCi should be restricted to special cases. A dose-effect relationship could not be detected in patients suffering from Basedow's disease. It seems recommendable here to use low initial doses so as to permit less radiosensitive patients to be healed by repeat treatment with a higher dose. (orig./MG) [de

    Full Text Available Background: Surgical management of posttraumatic elbow stiffness has been reported with poor outcome following treatment. Sequential release in earlier stages of stiffness yielded much better results. The goal of our study was to assess the outcome in improvement of the range of motion of the elbow after surgical release and to analyze a tailor-made approach according to individual needs to yield good result. Materials and Methods: A prospective study was conducted in 47 cases of elbow stiffness due to various types of injuries. All the cases were treated with sequential release if there was no progress after adequate supervised conservative management except in unreduced dislocations. All the cases were followed up for a minimum period of 24 months. Overall outcome was rated with the functional scoring system by Mayo Clinic Performance Index. Results: Twenty-five (44.68% out of 47 patients had excellent results with a mean preoperative range of motion of 33.9° and postoperative range of motion of 105° with net gain in range of motion of 71.1° (′ t ′ test value is 19.27, P < 0.01. None of the patients had elbow instability. Patients not having heterotopic ossification, who underwent surgery from three to six months post injury had a mean gain of 73.5°. In patients who waited for more than six months had mean gain of 66.8°. However, the results in cases having heterotopic ossification followed a slightly different pattern. In cases where release was performed from three months to six months had mean gain of 77.5°. Cases in which release was performed after six months had gain of 57.1°. Conclusions: In cases of posttraumatic elbow stiffness after a failed initial conservative treatment, early arthrolysis with sequential surgical soft tissue release yields good result than delayed surgery.

    Full Text Available Purpose: To discuss our treatment results of choroidal hemangiomas. Material and Method: The records of 39 cases of choroidal hemangioma followed up at our clinic between July 1999–October 2012 were reviewed retrospectively. Asymptomatic cases were followed up. Symptomatic cases with subretinal fluid and impaired vision received treatment. Results: Mean age of the 39 patients was 44 (12-80 years. Thirty-five of 39 cases had circumscribed choroidal hemangioma, and 4 cases had diffuse choroidal hemangioma. Sturge-Weber syndrome was present in 3 cases with diffuse choroidal hemangioma. Cases with circumscribed choroidal hemangioma and minimal subretinal fluid were treated with TTT in 11 cases, PDT in 12 cases, and PDT+TTT in 1 case. Cases with circumscribed choroidal hemangioma and excessive subretinal fluid were treated with Ru-106 plaque radiotherapy in 1 case, Ru-106 plaque radiotherapy+TTT in 1 case, EBRT in 3 cases, and TTT+EBRT in 1 case. One painful blind eye with neovascular glaucoma and complicated cataract was enucleated. Cases with diffuse choroidal hemangioma and excessive subretinal fluid were treated with Ru-106 plaque radiotherapy+TTT in 1 case and EBRT in 1 case. Ahmed glaucoma valve implantation and FAKO emulsification were applied to a case with neovascular glaucoma and complicated cataract. Complete resorption of subretinal fluid was achieved in 23 (72% of treated 32 cases. When mean initial tumor thickness was 2.6 mm (0.5-6, mean final tumor thickness was 1.4 mm (0-6. When mean initial visual acuity (LogMAR was 1.5 (0-3, mean final visual acuity was 1.1 (0-3. No recurrence was observed. Discussion: The amount of the subretinal fluid determines the method of treatment in circumscribed choroidal hemangioma. While TTT and PDT are effective treatment modalities for minimal subretinal fluid, plaque radiotherapy and EBRT are applied in cases with excessive subretinal fluid. Combination therapies may be necessary according to the

    The aim of this article is to present a state-of-the-art review of the scientific studies that have evaluated healthcare systems, services and programs for addiction treatment in Latin America. As a secondary aim, this article presents a brief description and analysis of the addiction prevention and treatment resources and programs available in Latin America, based on information from the ATLAS on Substance Use (ATLAS-SU) project led by the WHO. Substance use disorders (SUDs) are among the main causes associated with global burden of disease. Around the world, many initiatives have been proposed to promote policies to reduce substance use and reduce the impact of SUD, including integrating treatments into healthcare systems, increasing access to treatment programs and impacting outcome measures. In Latin America, multiple efforts have been implemented to improve addiction services and programs, although little is known about the impact they have generated. International studies report the availability of strategies and public inicitatives on prevention and treatment of addiction in Latin America. These studies also report established networks of public and private services that include prevention and detoxification programs, outpatient and residential treatment, and also social reintegration initiatives. However, despite these advances, information on the evaluation of the progress, results and impact of these programs is limited.

    Dental unit water systems are contaminated with biofilms that amplify bacterial counts in dental treatment water in excess of a million colony forming units per milliliter (cfu/ml). The Centers for Disease Control and Prevention and the American Dental Association have agreed that the maximum allowable contamination of dental treatment water not exceed 500 cfu/ml. This study was conducted to evaluate two protocols in controlling contamination of dental unit water systems and dental treatment water. Both methods used an antimicrobial self-dissolving chlorine dioxide (ClO₂) tablet at a high concentration (50 ppm) to shock the dental unit water system biofilms initially followed by periodic exposure. To treat dental treatment source water for patient care, 3 parts per million (ppm) ClO₂ in municipal/tap water was compared to use of a citrus botanical extract dissolved in municipal water. Heterotrophic microbial counts of effluent water and laser scanning confocal microscopy were performed to evaluate effects of the two treatments.

    Full Text Available Objective. To assess efficacy and tolerance of varfarin in prophylaxis and therapy of thrombotic complications in patients with antiphospholipid syndrome (APS. Methods. 20 pts with APS (5 male and 15 female received varfarin during a year. 8 of them had primary APS (PAPS and 12 -systemic lupus erythematosus with APS (SLE+APS. 2 other pts (I with SLE+APS and I with PAPS received varfarin during the last 4 years. Nobody from 9 pts with PAPS received corticosteroids (CS. In SLE+APS pts CS dose varied from 4 to 20 mg/day and was not increased during follow up. During the study prothrombine time (PT was examined with thromboplastin ( manufactured by Renam having international sensitivity index 1,2 and international normalization relation (INR. Depending on treatment scheme APS pts were divided into 3 groups. Group 1 included 8 pts with INR<2,0, Group 2-7 with INR >3,0, group 3 - 7 pts with INR<2,0 receiving as additional treatment thrombo ASS 100 mg/day and vasonit from 600 to 1200 mg/day. Results. Two pts with INR = 1,8 had thrombosis recurrence (due to leg thrombophlebitis. There were no recurrences in other groups. 2 from 22 pts had "large" bleedings. "Small" bleedings episodes were noted in 7 from 22 pts. Largely that were subcutaneous bleedings (in 4 pts no more than 5 cm of size. Two pts receiving varfarin with INR 1,8 and 2,4 had renal colic. Conclusion. Our preliminary results prove the necessity of inclusion of varfarin in the treatment of pts with APS and thrombosis but intensive anticoagulant effect is not always desired.

    The results of 131 I treatment were analyzed in 512 out of 1,620 cases of hyperthyroid patients treated with 131 I from 1963 to 1967 at Ito Hospital, Tokyo. The incidence of hypothyroidism, diagnosed clinically referring serum T 3 , T 4 and metabolic index, was 28.5%, euthyroidism 66.4% and hyperthyroidism 5.1%. Fourty one percent of euthyroid cases had high levels of serum TSH. While TRH tests were performed in 11 euthyroid cases with normal TSH levels, TSH response was normal in only 3 of the cases. Since there was no difference in the incidence of hypothyroidism among patients receiving a single dose of 6,001 - 7,000, 7,001 - 8,000 and 8,001 - 9,000 rads, relationship between the results of therapy and various factors which might influence the outcome of therapy was investigated in these cases. The incidence of hypothyroidism was higher in patients with shorter period between the onset of hyperthyroid symptoms and 131 I therapy, previous therapy with external irradiation, small goiter, severe exophthalmus, and shorter effective half life of 131 I at the time of treatment. Three cases of thyroid cancer and 2 cases of leukemia were observed in 823 patients which included 311 cases followed up only by inquiry. (author)

    Background: Recalcitrant lateral epicondylitis (elbow extensor–origin tendinosis) is a common cause of elbow pain with many treatment options. In the present study, the medium-term results after open release and radiofrequency microtenotomy are reported. Hypothesis: Microtenotomy would provide long-term pain relief that was as good as the open release method. Study Design: Prospective, randomized trial. Methods: Twenty-four patients randomized to either open release or microtenotomy were assessed after 5 to 7 years. Clinical examination and dynamic infrared thermography (DIRT) of both elbows were performed preoperatively and at the medium-term follow-up. Magnetic resonance imaging (MRI) of both elbows was performed at the medium-term follow-up. Results: Significant pain reduction was found using a visual analog scale (VAS) at the medium-term follow-up in both groups compared with the preoperative assessment (P lateral epicondylitis. The hypothesis was thus verified. PMID:26535247

    The aim of this study was to compare planning target volume (PTV) defined on respiratory-gated positron emission tomography (PET)/CT (RG-PET/CT) to PTV based on ungated free-breathing CT and to evaluate if RG-PET/CT can be useful to personalize PTV by tailoring the target volume to the lesion motion in lung cancer patients. Thirteen lung cancer patients (six men, mean age 70.0 years, 1 small cell lung cancer, 12 non-small cell lung cancer) who were candidates for radiation therapy were prospectively enrolled and submitted to RG-PET/CT. Ungated free-breathing CT images obtained during a PET/CT study were visually contoured by the radiation oncologist to define standard clinical target volumes (CTV1). Standard PTV (PTV1) resulted from CTV1 with the addition of 1-cm expansion of margins in all directions. RG-PET/CT images were contoured by the nuclear medicine physician and radiation oncologist according to a standardized institutional protocol for contouring gated images. Each CT and PET image of the patient's respiratory cycle phases was contoured to obtain the RG-CT-based CTV (CTV2) and the RG-PET/CT-based CTV (CTV3), respectively. RG-CT-based and RG-PET/CT-based PTV (PTV2 and PTV3, respectively) were then derived from gated CTVs with a margin expansion of 7-8 mm in head to feet direction and 5 mm in anterior to posterior and left to right direction. The portions of gated PTV2 and PTV3 geometrically not encompassed in PTV1 (PTV2 out PTV1 and PTV3 out PTV1) were also calculated. Mean ± SD CTV1, CTV2 and CTV3 were 30.5 ± 33.2, 43.1 ± 43.2 and 44.8 ± 45.2 ml, respectively. CTV1 was significantly smaller than CTV2 and CTV3 (p = 0.017 and 0.009 with Student's t test, respectively). No significant difference was found between CTV2 and CTV3. Mean ± SD of PTV1, PTV2 and PTV3 were 118.7 ± 94.1, 93.8 ± 80.2 and 97.0 ± 83.9 ml, respectively. PTV1 was significantly larger than PTV2 and PTV3 (p = 0.038 and 0.043 with Student's t test, respectively). No

    The demand for hair and tattoo removal with laser and IPL technology (intense pulsed light technology) is continually increasing. Nowadays these treatments are often carried out by medical laypersons without medical supervision in franchise companies, wellness facilities, cosmetic institutes and hair or tattoo studios. This is the first survey is to document and discuss this issue and its effects on public health. Fifty patients affected by treatment errors caused by medical laypersons with laser and IPL applications were evaluated in this retrospective study. We used a standardized questionnaire with accompanying photographic documentation. Among the reports there were some missing or no longer traceable parameters, which is why 7 cases could not be evaluated. The following complications occurred, with possible multiple answers: 81.4% pigmentation changes, 25.6% scars, 14% textural changes and 4.6% incorrect information. The sources of error (multiple answers possible) were the following: 62.8% excessively high energy, 39.5% wrong device for the indication, 20.9% treatment of patients with darker skin or marked tanning, 7% no cooling, and 4.6% incorrect information. The causes of malpractice suggest insufficient training, inadequate diagnostic abilities, and promising unrealistic results. Direct supervision by a medical specialist, comprehensive experience in laser therapy, and compliance with quality guidelines are prerequisites for safe laser and IPL treatments. Legal measures to make such changes mandatory are urgently needed. © The Authors | Journal compilation © Blackwell Verlag GmbH, Berlin.

  19. Process evaluation of treatment times in a large radiotherapy department

    2016-01-01

    Purpose/objective: The Department of Health (DH) recognises access to appropriate and timely radiotherapy (RT) services as crucial in improving cancer patient outcomes, especially when facing a predicted increase in cancer diagnosis. There is a lack of ‘real-time’ data regarding daily demand of a linear accelerator, the impact of increasingly complex techniques on treatment times, and whether current scheduling reflects time needed for RT delivery, which would be valuable in highlighting current RT provision. Material/methods: A systematic quantitative process evaluation was undertaken in a large regional cancer centre, including a satellite centre, between January and April 2014. Data collected included treatment room-occupancy time, RT site, RT and verification technique and patient mobility status. Data was analysed descriptively; average room-occupancy times were calculated for RT techniques and compared to historical standardised treatment times within the department. Results: Room-occupancy was recorded for over 1300 fractions, over 50% of which overran their allotted treatment time. In a focused sample of 16 common techniques, 10 overran their allocated timeslots. Verification increased room-occupancy by six minutes (50%) over non-imaging. Treatments for patients requiring mobility assistance took four minutes (29%) longer. Conclusion: The majority of treatments overran their standardised timeslots. Although technique advancement has reduced RT delivery time, room-occupancy has not necessarily decreased. Verification increases room-occupancy and needs to be considered when moving towards adaptive techniques. Mobility affects room-occupancy and will become increasingly significant in an ageing population. This evaluation assesses validity of current treatment times in this department, and can be modified and repeated as necessary. - Highlights: • A process evaluation examined room-occupancy for various radiotherapy techniques. • Appointment lengths

    Rapid progress has been made in the treatment of Marfan syndrome. Today, the treatment is relatively established and the results have also improved. Even if surgery is performed, however, vascular lesions may recur late after operation and late prognosis is poor considering the age of patients. Issues such as whether a reoperation should be conducted or how the late results might be improved are subjects of debate. Based on an analysis of recent late data, we have performed operations according to the new treatment policy, and here report the results. A total of 203 consecutive operations were conducted in 141 patients with Marfan syndrome who underwent surgery for aortic aneurysm at our department between February 1973 and August 2001. The mean age of patients was 39 (11 years with a male/female ratio of 95:46. At the first operation, 72 patients were diagnosed with annuloaortic ectasia (AAE), 17 patients with AAE + chronic dissection (DeBakey I), 14 patients with AAE + chronic dissection (DeBakey II), 6 patients with AAE + acute dissection (Stanford A), 11 patients with AAE + dissection (DeBakey III), 9 patients with dissection (DeBakey III) only, 3 patients with AAE + abdominal aortic aneurysm only, and 2 patients with abdominal aortic aneurysm only. The cause of reoperation were a new lesion in 17 patients, dissection in 13 patients and a true aneurysm in 4 patients. In 36 patients, an increase in the remaining lesion occurred or a scheduled stage 2 operation was performed. Reoperation was performed following the Bentall operation in 7 patients, dehiscence of the anastomotic region of the coronary artery in 5 patients, aneurysm of the anastomotic region of the coronary artery in 1 patients, and infection of the artificial valve with aneurysm of the anastomotic region of the coronary artery in 1 patient. Hospital deaths were reported in 8 (6%) patients who underwent composite valve graft replacement (including simultaneous arch replacement) for AAE. Hospital

    Conservative treatment in severe preeclampsia has been documented by several authors citing significant improvement in neonatal outcome lacking a significant increase in maternal complications. Our objective was to inform of our preliminary results using protocolized conservative management in women with preeclampsia-eclampsia, favoring better neonate conditions. We included 34 patients with average age of 28.2 years with documented severe preeclampsia-eclampsia complicating a 36-weeks or less pregnancy, admitted in the obstetric intensive care unit (OICU) between October 2001 and February 2002. Patients received protocolized management consisting of intravascular colume expansion, anti-hypertensive control, target organ protection, monitoring, and clinical observation. We considered conservative management as a 24 or more period offered to patients with satisfactory response to medical treatment and no evidence of binomial compromise. Of our group, 85% corresponded to severe preeclampsia, 9% to eclampsia, 3% to imminence of eclampsia, and 3% to HELLP syndrome. Average stay in OICU was 5.5 days with 3.5 days average management before pregnancy was interrupted. These patients presented mean gestational age of 32.8 weeks during which we observed anemia, low platelets, D dimmer increments, MAP average of 112.8, PCOc 18.6, and BI 0.15. We obtained 36 live newborns of whom 12% four died, two were extremely immatures (510 g and 600 g, respectively); one 980-g newborn presented intraventricular hemorrhage, and a 1,450-g newborn had multiple organ failure. Conservative treatment in patients with severe preeclampsia-eclampsia is a feasible alternative in hospitals with an ICU. Conservative management can improve neonatal survival and prognosis in preterm newborns.

    The purpose of this study is to present the treatment results and to identify possible prognostic indicators in patients with locally advanced hypopharyngeal carcinoma. Materials and Methods: Between October 1985 to December 2000, 90 patients who had locally advanced stage IV hypopharyngeal carcinoma were studied retrospectively. Twelve patients were treated with radiotherapy alone, 65 patients were treated with a combination of chemotherapy and radiotherapy, and 13 patients were treated with surgery and postoperative radiotherapy with or without neoadjuvant chemotherapy. Total radiation dose ranged from 59.0 to 88.2 Gy (median 70 Gy) for radiotherapy alone. Most patients had ciplatin and 5-fluorouracil, and others had cisplatin and peplomycin or vincristin. Median follow-up period was 15 months. Kaplan-Meier method was used for survival rate and Cox proportional hazard model for multivariate analysis of prognostic factors. Results: Overall 3- and 5-year survival rates were 27% and 17%, respectively. The 2-year locoregional control rates were 33% for radiotherapy alone, 32% for combined chemotherapy and radiotherapy, and 81% for combined surgery and radiotherapy (p=0.006). The prognostic factors affecting overall survival were T stage, concurrent chemo radiation and treatment response. Overall 3- and 5-year laryngeal preservation rates in combined chemotherapy and radiotherapy were 26% and 22%, respectively. Of these, the 5-year laryngeal preservation rates were 52% for concurrent chemo radiation group (n=11), and 16% for neoadjuvant chemotherapy and radiotherapy (n=54, p=0.012). Conclusion: Surgery and postoperative radiotherapy showed better results than radiotherapy alone or with chemotherapy. Radiotherapy combined with concurrent chemotherapy is an effective modality to achieve organ preservation in locally advanced hypopharyngeal cancer. Further prospective randomized studies will be required

    An occult pneumothorax is found in 2-15% trauma patients. Observation (without tube thoracostomy) in these patients presents still some controversies in the clinical practice. The objective of the study is to evaluate the efficacy and the adverse effects when observation is performed. A retrospective observational study was undertaken in our center (university hospital level II). Data was obtained from a database with prospective registration. A total of 1087 trauma patients admitted in the intensive care unit from 2006 to 2013 were included. In this period, 126 patients with occult pneumothorax were identified, 73 patients (58%) underwent immediate tube thoracostomy and 53 patients (42%) were observed. Nine patients (12%) failed observation and required tube thoracostomy for pneumothorax progression or hemothorax. No patient developed a tension pneumothorax or experienced another adverse event related to the absence of tube thoracostomy. Of the observed patients 16 were under positive pressure ventilation, in this group 3 patients (19%) failed observation. There were no differences in mortality, hospital length of stay or intensive care length of stay between the observed and non-observed group. Observation is a safe treatment in occult pneumothorax, even in pressure positive ventilated patients. Copyright © 2014 AEC. Publicado por Elsevier España, S.L.U. All rights reserved.

    The aims of the studies included in this thesis were: - to investigate the reliability of 201 Thallium single photon emission computed tomography. Tl SPECT for preoperative diagnosis and histological staging of malignant astrocytomas in comparison with CT; - to develop a method for quantification of cerebral thallium uptake, and to evaluate the quantitative measurement in comparison with CT, for astrocytoma treatment follow-up purposes; - to compare quantitative Tl SPECT and proton magnetic resonance spectroscopy (H-MRS) with conventional MR imaging for astrocytoma monitoring, and to evaluate associations between change of morphological tumour characteristics during treatment and changes of cerebral thallium uptake and metabolic ratios. Results and conclusions: - High TI-index, calculated as a ratio comparing tumour uptake to uptake in the contralateral hemisphere, is an indicator of highly malignant astrocytoma. Differentiation between the high-grade astrocytomas, the low-grade astrocytomas, and infectious lesions is only partial, with an overlap of Tl-indexes between these groups. High-grade astrocytomas that do not show contrast enhancement on CT, and astrocytomas with central necrosis and moderate ring-enhancement, tend to be underestimated when evaluated by Tl-index calculation. Tl SPECT is not a reliable method for non-invasive tumour staging among the group of highly malignant astrocytomas. - Quantification of cerebral TI-uptake, defining the volume of viable tumour tissue, is a new method for astrocytoma chemotherapy monitoring. Results suggest that the method provides prognostic information, and information of treatment efficacy, at an earlier stage than CT. - We did not find a higher accuracy of quantitative Tl SPECT than of MR for monitoring purposes and our results indicated that treatment induced MR changes were interrelated with TI-uptake variations. - Multi-voxel H-MRS was difficult to apply for astrocytoma treatment monitoring, due to the anatomical

    Basic principles in the therapy of idiopathic autoimmune hemolytic anemia induced by warm antibody were glucocorticoides and splenectomy. Immunosupresive drugs, plasmaferesis and intravenous high doses gamma globulin therapy are also useful. In secundary autoimmune hemolytic anemia induced by warm antibody we treated basic illness. During the period of 1990-1992 we treated 21 patients with primary autoimmune hemolytic anemia and 6 patients with secondary /4 CLL and 2 Non-Hodgkin's lymphoma/. Complete remission we found as a normalisation of reticulocites and hemoglobin level respectively. Complete remission by corticoides we got in 14/21 patients, partial response in 2/21 respectively. Complete response by splenectomy we got in 2/3 splenoctomized patients (idiopathic type). For successful treatment secondary hemolytic anemias we treated primary diseases (CLL and malignant lymphoma) and we got in 4/6 patients complete remission. Our results were standard in both type of autoimmune hemolytic anaemias induced by warm antibody.

    Here we present, to the best of our knowledge, the first case of a paraneoplastic Cushing's syndrome (hypercortisolism) resulting from treatment-related neuroendocrine prostate cancer - a highly aggressive and difficult disease to treat. A 51-year-old man was started on androgen deprivation therapy after presenting with metastatic prostate cancer, characterized by diffuse osseous metastasis. Shortly thereafter, he developed progressive disease with biopsy proven neuroendocrine prostate cancer as well as symptoms of increased skin pigmentation, hypokalemia, hypertension, hyperglycemia and profound weakness, consistent with ectopic Cushing's syndrome. Molecular analysis of the patient's tumor through RNA sequencing showed high expression of several genes including CHGA, ASCL1, CALCA, HES6, PCSK1, CALCB and INSM1 confirming his neuroendocrine phenotype; elevated POMC expression was found, supporting the diagnosis of ectopic Cushing's syndrome. © 2016 The Japanese Urological Association.

    Full Text Available The present study concerns the influence of cementitious binder on electrochemical treatment of steel embedded in salt contaminated mortar. As binder, ordinary Portland cement (OPC and ground granulated blast furnace slag (GGBS were used and the current density of 250–750 mA/m2 was applied for 4 weeks to complete electrochemical chloride extraction. To evaluate the effect of electrochemical treatment the chloride profile and corrosion behaviour covering chloride concentration, galvanic current density, linear polarization resistance, open circuit potential, and mass loss were measured. An increase in the applied direct current density resulted in a decrease in the chloride concentration at the vicinity of steel, accompanying the mitigated corrosion damage. The performance of electrochemical treatment was more remarkable in mortar containing GGBS presumably due to binding mechanism. However, corrosion damage was more detrimental in GGBS rather than OPC at a given potential, while GGBS had superior corrosion resistance to a corrosive environment and treatment conditions. Therefore, the electrochemical treatment should be conducted prudently to evaluate the corrosion state of embedded steel depending on binder type.

    Even though modern concepts of disease management of unspecific low back pain (LBP) postulate active participation of patients, this strategy is difficult to adapt unless multidisciplinary pain therapy is applied. Recently, mobile health solutions have proven to be effective aides to foster self-management of many diseases. The objective of this paper was to report on the retrospective short-term results of a digital multidisciplinary pain app for the treatment of LBP. Kaia is a mobile app that digitalizes multidisciplinary pain treatment and is in the market as a medical product class I. For the current study, the data of anonymized Kaia users was retrospectively analyzed. User data were evaluated for 12 weeks regarding duration of use and effect on in-app user reported pain levels, using the numerical rating scale (NRS), depending on whether LBP was classified as acute, subacute, or chronic back pain according to current guidelines. Data of 180 users were available. The mean age of the users was 33.9 years (SD 10.9). Pain levels decreased from baseline NRS 4.8 to 3.75 for all users at the end of the observation period. Users who completed 4, 8, or 12 weeks showed an even more pronounced decrease in pain level NRS (baseline 4.9 [SD 1.7] versus 3.6 [SD 1.5] at 4 weeks; baseline 4.7 [SD 1.8] versus 3.2 [SD [2.0] at 8 weeks; baseline 4.6 [SD 2.2] versus 2.6 [SD 2.0] at 12 weeks). In addition, subgroup analysis of acute, subacute, or chronic classification revealed no significant main effect of group (P>.30) on the reduction of pain. Conclusions: This retrospective study showed that in a pre-selected population of app users, an app digitalizing multidisciplinary rehabilitation for the self-management of LBP reduced user-reported pain levels significantly. The observed effect size was clinically relevant. Ongoing prospective randomized controlled trials (RCTs) will adjust for potential bias and selection effects. This retrospective study showed that in a pre

    This study was undertaken to analyze the efficacy and sphincter preservation rate of platinum based neoadjuvant chemotherapy plus radiotherapy versus abdominoperineal resection and postoperative radiotherapy for anal cancer. Data of forty-two patients with anal cancer were retrospectively analyzed. Among thirty-eight patients with epidermoid histology, four patients received radiotherapy, and nineteen patients received abdominoperineal resection and adjuvant radiotherapy with or without chemotherapy (APR + RT {+-} CT), and fifteen patients received neoadjuvant chemotherapy and radiotherapy (CRT). The CRT regimen was composed of three cycles of 5-fluorouracil (1,000 mg/m{sup 2} bolus on D1 {approx} 5) and cisplatin (60 mg/m{sup 2} bolus on D1) followed by 50.4 Gy to the tumor bed and regional lymphatics over 5.5 weeks. Both inguinal lymphatics were treated with an identical dose schedule. Residual disease was treated with an additional three cycles of identical adjuvant chemotherapy. An identical dose schedule was used for post-operative radiotherapy. Median follow-up period was eighty-five months. Overall five-year survival rates were 80.3%, 88.9% and 79.4% for entire patients, APR + RT {+-} CT group, and the CRT group, respectively. No significant difference was found between the two groups ({rho} = 0.49). Anus preservation rate for the CRT group was 86.7%. Age ({rho} = 0.0164) and performance status ({rho} = 0.0007) were found to be significant prognostic factors by univariate analysis. Age ({rho} = 0.0426), performance status ({rho} = 0.0068), and inguinal lymph node metastasis ({rho} = 0.0093) were statistically significant prognostic factors by multivariate analysis. No case of RTOG grade 3 complication or higher was reported. This and other recent studies have shown that combined chemotherapy plus radiotherapy for anal cancer results in a high rate of anal sphincter preservation as well as local control and survival. Furthermore, neoadjuvant use of

    Full Text Available . Introduction: Decision-making when facing a pediatric cancer treatment deserves a spotlight due to the amount of decisions that parents must deal with during this process, which may often generate emotional stress, doubts, uncertainties and anxieties. Thus, assessing how the health team influences the decision of parents is an important factor to evaluate how much autonomy they have to be able to choose on the numerous possibilities resulting from the treatment. Objective: To evaluate parents’ decision-making process in oncologic pediatric treatments and to analyze the perception of coercion, the level of moral-psychological development and other difficulties. Method: 10 participants were selected by convenience to conduct individual semi-structured interviews, applying the Scale of Perception of Coercion in Assistance and the Moral-Psychological Development Scale. Results: Nine mothers and one father were interviewed (n = 10, with an average age of 33.1 years. Six categories were identified from the analysis of content originated from the central theme. There was no perception of coercion by parents and all have shown psychological and moral levels suitable for decision-making. Conclusion: It was observed that, in spite of emotional difficulties, parents have proved able to decide on issues related to the treatment of their children, having enough autonomy for decision-making.

    OBJECTIVE To describe how primary care clinicians can detect an eating disorder and identify and manage the associated medical complications. DESIGN A review of literature from 1994 to 1999 identified by a medlinesearch on epidemiology, diagnosis, and therapy of eating disorders, including anorexia nervosa and bulimia nervosa. MEASUREMENTS AND MAIN RESULTS Detection requires awareness of risk factors for, and symptoms and signs of, anorexia nervosa (e.g., participation in activities valuing thinness, family history of an eating disorder, amenorrhea, lanugo hair) and bulimia nervosa (e.g., unsuccessful attempts at weight loss, history of childhood sexual abuse, family history of depression, erosion of tooth enamel from vomiting, partoid gland swelling, and gastroesophageal reflux). Providers must also remain alert for disordered eating in female athletes (the female athlete triad) and disordered eating in diabetics. Treatment requires a multidisciplinary team including a primary care practitioner, nutritionist, and mental health professional. The role of the primary care practitioner is to help determine the need for hospitalization and to manage medical complications (e.g., arrhythmias, refeeding syndrome, osteoporosis, and electrolyte abnormalities such as hypokalemia). CONCLUSION Primary care providers have an important role in detecting and managing eating disorders. PMID:10940151

    High-pressure injection injuries of the hand have a reputation for being dangerous for individual fingers and even for whole hand. Usually appearing innocuous at presentation because of small puncture entry wound, these injuries result in severe damage of most internal structures in finger and hand due to extensive penetration of injected substance. This paper reviews the outcome of the treatment of such injuries in 10 patients: 9 sustained injection of toxic paint, and one lead shot. All the patients were operated on: eight a few hours after injury and two with 3 days delay. The surgical technique included wide exposure from site of injection up to the farthest place in which foreign substance was seen. Thorough debridment of injected material and contaminated tissue was performed with careful preservation of neurovascular structures and tendons. Wounds were not closed, but managed by open technique. In all patients wounds healed well: in 3 by secondary intention, in 6 by delayed closure and 2 were covered by skin grafts. No amputation was performed. Final results were assessed form 1.5 to 3.5 years after initial injury (mean at 2.5 years). Two patients complained of moderate pain related to the weather, five of cold intolerance and two of impaired sensation on fingertips. Active range of motion of affected fingers was in whole group from 90% to 104% (mean 97%) of the range of motion of unaffected fingers from the other side. Range of motion of the wrist (2 patients) was 76% and 117% of range of motion of the other side. Pinch grip strength was from 81% to 116% (mean 99%), and global grip strength from 77% to 119% (mean 97%) of the other side. All patients went back to their previous jobs and periods of sick leave were from 2 weeks to 6 months (mean 3 mo). Excellent results achieved in this study--full functional recovery in 9 of 10 patients confirm the effectiveness of aggressive treatment by open wound technique of such injuries.

    The cell phone is an indispensable service facilitator, however, the disposal and recycling of cell phones is a major problem. While the potential life span of a mobile phone, excluding batteries, is over 10 years, most of the users upgrade their phones approximately four times during this period. Cell phone waste is significantly more hazardous than many other municipal wastes as it contains thousands of components made of toxic chemicals and metals like lead, cadmium, chromium, mercury, polyvinyl chlorides (PVC), brominated flame retardants, beryllium, antimony and phthalates. Cell phones also use many expensive rare metals. Since cell phones are made up of plastics, metals, ceramics, and trace other substances, primitive recycling or disposal of cell phone waste to landfills and incinerators creates irreversible environmental damage by polluting water and soil, and contaminating air. In order to minimize releases into the environment and threat to human health, the disposal of cell phones needs to be managed in an environmentally friendly way. This paper discussed a safer method of reducing the generation of syngas and hydrocarbons and metal recovery through the treatment of cell phone wastes by a thermal plasma. The presentation discussed the experiment, with particular reference to sample preparation; experimental set-up; and results four samples with different experimental conditions. It was concluded that the plasma treatment of cell phone waste in reduced condition generates gaseous components such as hydrogen, carbon monoxide, and hydrocarbons which are combustible. Therefore, this system is an energy recovery system that contributes to resource conservation and reduction of climate change gases. 5 refs., 2 tabs., 2 figs.

    The purpose of the present paper was to review the results of treating early stages glottic, squamous cell carcinoma by radiotherapy in the Department of Radiation Oncology, Prince of Wales Hospital, Sydney. A retrospective review was carried out of all patients seen in the department from 1967 to 1994, inclusive. To be eligible, patients had to have newly diagnosed cancer and to have been treated with curative intent by radiotherapy alone. Three hundred and sixty-nine patients satisfied the eligibility requirements. The mean follow-up time was 12.2 years (maximum: 28 years). At 5 years the actuarial local control rate was 80% (84% for stage T 1 and 72% for T 2 ). The ultimate local control rate was 96%. The overall survival rates at 5 and 10 years were 73% and 52%, respectively. The risk of nodal recurrence was much higher after persisting disease or local recurrence. Our results confirm the high cure rates achieved with this modality of treatment and are comparable with those reported in the literature. Copyright (1999) Blackwell Science Pty. Ltd

    Full Text Available Agave americana contains inulin as storage carbohydrate. Therefore, agave is interesting to be used for the extraction of inulin by pressing. The yield of the process is low due to the high hardness of the core. The objective of this work was to evaluate pretreatments to reduce the hardness in the process of obtaining inulin by pressing. Treatments with water, sulphuric acid 1 % (by mass or sodium hydroxide 1 % (by mass were tested and optimized. The pretreatment of the core of A. americana with sulphuric acid 1 % allowed the reduction of hardness from 30 000 g to 2000 g of breaking force. The mathematical model obtained predicts an optimum processing at 84 °C during 75 min. The treatment with sulphuric acid 1 % also allows white core of A. americana to be obtained, while the other treatments provide yellow core. These results open a good alternative to obtain value added products from this resource.

    BACKGROUND: Among the chronic leg ulcers, venous ulcers are the most common and constitute a major burden to public health. Despite all technology available, some patients do not respond to established treatments. In our study, carboxymethylcellulose was tested in the treatment of refractory chronic venous ulcers. OBJECTIVE: To evaluate the efficacy of carboxymethylcellulose 20% on the healing of chronic venous ulcers refractory to conventional treatments. METHODS: This is an analytical, pre-experimental study. Thirty patients were included with refractory venous ulcers, and applied dressings with carboxymethylcellulose 20% for 20 weeks. The analysis was based on measurement of the area of ulcers, performed at the first visit and after the end of the treatment. RESULTS: There was a reduction of 3.9 cm2 of lesion area (p=0.0001), corresponding to 38.8% (p=0.0001). There was no interruption of treatment and no increase in lesion area in any patient. CONCLUSIONS: Carboxymethylcellulose 20% represents a low cost and effective therapeutic alternative for the treatment of refractory chronic venous ulcers. However, controlled studies are necessary to prove its efficacy. PMID:26982773

    , both the calculation method and the application of DCF can change the ranking order of competing plans. The voxel-by-voxel TCP model makes it feasible to incorporate spatial variations of clonogen densities (n), radiosensitivities (SF2), and fractionation sensitivities (alpha/beta) as those data become available. The new software incorporates both spatial and biological information into the treatment planning process. The application of multiple methods for the incorporation of biological and spatial information has demonstrated that the order of application of biological models can change the order of plan ranking. Thus, the results of plan evaluation and optimization are dependent not only on the models used but also on the order in which they are applied. This software can help the planner choose more biologically optimal treatment plans and potentially predict treatment outcome more accurately.

    We conducted a series of studies in which multiple strategies were used to clarify the inconclusive results of one boy’s functional analysis of aggression. Specifically, we (a) evaluated individual response topographies to determine the composition of aggregated response rates, (b) conducted a separate functional analysis of aggression after high rates of disruption masked the consequences maintaining aggression during the initial functional analysis, (c) modified the experimental design used during the functional analysis of aggression to improve discrimination and decrease interaction effects between conditions, and (d) evaluated a treatment matched to the reinforcer hypothesized to maintain aggression. An effective yet practical intervention for aggression was developed based on the results of these analyses and from data collected during the matched-treatment evaluation. PMID:25891269

    The methods and results of treatment for cancer of the cervical esophagus differ from those for cancer of the thoracic esophagus. Our objective was to retrospectively review the outcome for cervical esophageal cancer patients treated with radiotherapy. Twenty-seven patients with carcinoma of the cervical esophagus treated with definitive radiotherapy from 1988 to 2002 were enrolled in the study. Clinical stage (UICC 1997) was stage I in five, II in six, III in 12 and IV in four. Concurrent head and neck malignancy was found in six patients (22%). The mean radiation dose was 66 Gy. Concurrent chemotherapy (cisplatin and 5-fluorouracil) was performed in 23 patients. The actuarial overall survival rates at 1, 3 and 5 years were 55.6%, 37.9% and 37.9%, respectively, with a median survival of 13.9 months. In the patients with stage I, the 3-year and 5-year survival rates were 75% and 75%, respectively. With univariate analysis, only two of the possible prognostic factors were found to actually influence survival: performance status (p<0.01) and tumor length (p<0.01). The survival of patients with cervical esophageal cancer remains poor. It is thought that organ preservation is possible by definitive chemoradiation for early cancer

    Hull wastes and some scrapped equipment are typical radioactive wastes generated from reprocessing process in Tokai Reprocessing Plant (TRP). Because hulls are the wastes remained in the fuel shearing and dissolution, they contain high radioactivity. Japan Nuclear Cycle Development Institute (JNC) has started the project of Hull Waste Treatment Facility (HWTF) to treat these solid wastes using compaction and incineration methods since 1993. It is said that Zircaloy fines generated from compaction process might burn and explode intensely. Therefore explosive conditions of the fines generated in compaction process were measured. As these results, it was concluded that the fines generated from the compaction process were not hazardous material. This paper describes the outline of the treatment process of hulls and results of safety evaluation

    Full Text Available Objective To formulate the best treatment plan for multiple sclerosis (MS patients by evaluating the therapeutic efficacy and side effect of various evidence-based programs. Methods Key words were defined as multiple sclerosis, immunomodulatory therapy and therapy, etc. We searched MEDLINE, Cochrane Library, Wanfang data bases for Scientific Journals in China and National Knowledge Infrastructure for Chinese Scientific Journals Database. Additionally, we applied manual searching and screened out conference paper and academic dissertation, etc, from various references. After that we obtained and evaluated by Jadad scales on systematic reviews, randomized controlled trials, controlled clinical trials and observational study cases about glucocorticoids, plasmapheresis, intravenous immunoglobulin, IFN-β, glatiramer acetate, mitoxantrone, natalizumab, fingolimod. Results After screening, all seventeen selected resources included systematic reviews 6 articles, randomized controlled trials 7 articles, controlled clinical trials 2 articles, observational study cases 2 articles, among which fifteen articles were proved to be high quality (according to Jadad scoring system, five score 4, six score 5, four score 7, two chapters were judged to be low quality scoring 3. Finally, we summerize that: 1 The first choice of treatment for acute relapses is glucocorticoids and we suggest that plasmapheresis or intravenous immunoglobulin may be tried as an alternative therapy in acute MS relapse, especially in case of contraindications to intravenous methylprednisolone. 2 Immunomodulatory or immunosuppressive treatment (IFN-β, glatiramer acetate, mitoxantrone, natalizumab can be an option to prevent new relapses and progression of disability. 3 Fingolimod is an oral treatment for multiple sclerosis to improve treatment adherence. Conclusion Using evidence-based medicine methods can provide us best clinical evidence on MS treatment.

The objective of this program is to verify the performance of products that provide nutrient reduction in wastewater from a variety of sources, including domestic wastewater, agricultural runoff, or other waste streams. The evaluation process will be overseen and coordinated by the Environmental Technology Evaluation Center (EvTEC), a program of the Civil Engineering Research Foundation (CERF), the research and technology transfer arm of the American Society of Civil Engineers (ASCE). EvTEC is a pilot program evaluating innovative environmental technologies under the US Environmental Protection Agency's (USEPA) Environmental Technology Verification (ETV) Program. Among other performance issues, the potential energy savings of using nutrient reducing technologies scaled to treat low flows - larger than an individual septic tank but smaller than that of a conventional wastewater treatment plant - will be assessed. The energy savings realized by reduced construction and equipment transport costs alone could make low-flow nutrient reduction technologies viable options for rural communities, small farms, and other low-flow settings. The evaluation is being funded in part by PADEP, which is sponsoring this evaluation due to its interest in developing low-cost wastewater treatment technologies for Pennsylvania's rural communities. However, the evaluation is national in scope, and participants will come from all areas of the country. The presentation will include a description of the process for establishing the testing protocol, testing results from various nutrient reducing technologies, and obstacles encountered and lessons learned during the process.

    Criteria were developed for evaluating the participants analytical results in the DOE Quality Assessment Program (QAP). Historical data from previous QAP studies were analyzed using descriptive statistical methods to determine the interlaboratory precision that had been attained. Performance criteria used in other similar programs were also reviewed. Using these data, precision values and control limits were recommended for each type of analysis performed in the QA program. Results of the analysis performed by the QAP participants on the November 1983 samples were statistically analyzed and evaluated. The Environmental Measurements Laboratory (EML) values were used as the known values and 3-sigma precision values were used as control limits. Results were submitted by 26 participating laboratories for 49 different radionuclide media combinations. The participants reported 419 results and of these, 350 or 84% were within control limits. Special attention was given to the data from gamma spectral analysis of air filters and water samples. both normal probability and box plots were prepared for each nuclide to help evaluate the distribution of the data. Results that were outside the expected range were identified and suggestions made that laboratories check calculations, and procedures on these results

    Between 1964 to 1990, 458 patients diagnosed of bladder cancer have been treated with radical radiotherapy in our department. The 5-years and 10-years actuarial survival rates were 37% and 27% respectively. The 5-years and 10-years actuarial local control rates, evaluated in 404 patients, were 41% and 38%. In regard to survival, T stage (p=0.013), advanced intravesical extension or multicentrity (p>0.0001), and squamous differentiation (p<0.0001), reached statistical significance as adverse prognostic factors. In 248 patients, with invasive transitional carcinoma, radical radiotherapy alone was used. In this group of patients, T stage (p=0.006) and advanced intravesical extension or multicentrity (p=0.0002) were adverse prognostic factors for survival. Our results suggest that radical radiotherapy must be considered and alternative to surgery in management of bladder cancer. On the basis of prognostic factors evidenced in this series a subgroup of patients with low probability of survival when treated with exclusive radiotherapy are defined. This patients must be included in clinical research protocols. (Author) 44 refs

    The effect of various forms of treatment of renal osteodystrophy was evaluated in 25 dialysis patients by quantitative bone scintigraphy, using 99m-Tc-HEDP. The results were compared with those of biochemical and bone morphometric studies. The total skeletal activity (TSA) decreased in 5 patients after transplantation, in 11 after parathyroidectomy and in 6 out of 9 treated conservatively, but did not normalize in any of the patients. Bone morphometric evaluation of treatment, which could be performed in 19 of the 20 patients who did not receive a transplant, demonstrated a reduction in the degree of hyperparathyroidism in 17 patients (89 percent). Osteoid excess was reduced in 13 patients (68 percent) but an evident reduction of osteomalacic osteoid, i.e. improvement of osteomalacia, occurred in only 4 patients (21 percent). Changes in the TSA correlated significantly with the changes in the biochemical and histological parameters of hyperparathyroidism, but not with the changes in osteoid excess. These results indicate that, during treatment of renal osteodystrophy, changes in (quantitative) bone scintigraphy primarily indicate changes in the degree of hyperparathyroidism.

    In July 1995, a questionnaire was forwarded to thirty two physicists overseeing Radiation Oncology Departments and brachytherapy in hospitals throughout Australia and New Zealand. From the thirty seven hospitals reached by this survey, details were gathered on thirty hospitals, including the Newcastle In most radiotherapy centres where treatment planning is performed by radiation therapists, at least some of the treatment sheets and their calculations are double checked by radiotherapy physicists. While 23% checked the treatment sheets of all patients, in the majority of centres physicists were found to check only a minor selection, that is, less than 20% of all treatment sheets. Only in six centres physicists were not involved. 5 refs., 4 tabs., 5 figs

    A retrospective review of thirty-eight patients (16 males and 22 females) with spinal infection between 1993 and 1998 revealed that the mean age was 39.9 years and the peak incidence was in the 5th decade of life. Infections in thirty-two patients (84.2%) were tuberculous in origin, 13.2% were pyogenic and 2.6% were fungal. Back pain was a symptom in 94.7% while 55.8% had neurological deficits, of which two-thirds were tuberculous in origin. Twenty-two patients (57.9%) had an impaired immune status secondary to pulmonary either tuberculosis, diabetes mellitus, intravenous drug abuse, prolonged steroid treatment, malnutrition, or advanced age. History of contact with tuberculous patients was elicited in 31.3%, extraskeletal tuberculosis was found in 28.1%, while Mantoux test was only positive in 53.1% of tuberculous patients. Majority of the cases (57.9%) involved lumbar vertebra. The histopathological examination was only positive in 22.2% from material taken via CT guided biopsy but 93.3% were found to be conclusive from open biopsy. 4 out of 5 patients who had a pyogenic infection were treated conservatively and produced a good result. There was no difference in outcome for tuberculosis patients treated with either the 3 drug or 4 drug regimen. Anterior decompression and bone grafting in tuberculous patients was superior in terms of a faster fusion rate, early pain relief and prevention of kvphotic deformity. The initial neurological deficit did not reflect the future prognosis of patients with spinal infection.

    Full Text Available Objective: To evaluate the correlation between wound cosmesis and pet owner satisfaction, to determine the agreement among vet surgeons, and pet owners evaluating a surgical wound with a visual assessment score (VAS, and to determine the agreement between the VAS, a semi-quantitative score of wound inflammation, and wound width.Background: Perception of post-surgical cosmesis by human patients has been found to influence their satisfaction and perceived adequacy of vet surgeons. Due to the trend of owners anthropomorphising pets, this logic can be extended to veterinary patients. Also, there is a lack of consistent, reliable methods to evaluate cosmesis have been developed, creating the need for a scoring system that is accurate and reproducible.Evidentiary value: This was a prospective cohort study with one hundred and seven patients. This study may not change day-to-day practices, but it will bring to light for practitioners the discordance between pet owners and vet surgeons concerning attractiveness of an incision as well as overall satisfaction with a procedure.Methods: Photographs of surgical wounds were taken immediately, 2 weeks, and 8 weeks after surgery in dogs. Owners were asked to evaluate satisfaction with the procedure and attractiveness of the incision using the VAS. Photos were evaluated for cosmetic outcome by pet owner and vet surgeon evaluators with different scoring systems. The reliability of the scoring systems was evaluated using intraclass correlations and kappa statistics as appropriate.Results:  Owners’ evaluation of cosmetic outcome correlated with their overall satisfaction. (r2=0.37, where r2 is the coefficient of determination, and can be used to determine what proportion of variance in one variable is predictable from the other variableThere was generally poor reliability of the subjective scoring between both vet surgeons and pet owners, and the less subjective scoring systems.Conclusion: The cosmetic outcome

    Purpose: To investigate the treatment outcome and prognostic factors of adult medulloblastoma patients who received postoperative craniospinal irradiation (RT). Methods and Materials: Between 1983 and 2000, 30 adult patients (17 men and 13 women, age ≥16 years, median 27, range 16-45) underwent postoperative RT. The median duration of symptoms was 2 months (range 1-9). The tumor location was lateral in 16 (53%). A desmoplastic variant was seen in 12 (40%). Tumor resection was complete in 20 (67%) and incomplete in 10 (33%). All patients received craniospinal RT. The median dose to the whole brain was 40 Gy (range 36-51), to the posterior fossa 54 Gy (range 49-56), and to the spinal axis 36 Gy (range 24-40). The median interval between surgery and the start of RT was 31 days (range 12-69), and the median duration of RT was 45 days (range 34-89). Ten patients (33%) received adjuvant chemotherapy. The median follow-up was 51 months (range 5-215). Results: The 5- and 8-year overall survival and disease-free survival rates were 65% and 51% and 63% and 50%, respectively. Twelve patients (40%) developed relapse, with a median follow-up of 51 months. The posterior fossa was the most common site of relapse (6 patients). The median time to relapse was 26 months (range 4-78). Fifty percent of the relapses occurred after 2 years, 17% after 5 years. In univariate analysis, M stage and the interval between surgery and the start of RT were significant prognostic factors for disease-free survival. At 5 years, 70% of M0 patients were estimated to be disease-free, but none of the 3 M3 patients reached 5 years without recurrence (p=0.0002). The 5-year disease-free survival rate for the patients whose interval between surgery and the start of RT was 6 weeks was 0%, 85%, and 75%, respectively (p=0.002). The 5-year posterior fossa control rate for patients who received ≥54 Gy or <54 Gy to the posterior fossa was 91% and 33%, respectively (p=0.05). Conclusion: The survival results

    Some of the results of a safety evaluation performed on current generic types of BWR off-gas treatment systems including cooled and ambient temperature adsorber beds and cryogenics are presented. The evaluation covered the four generic types of off-gas systems and the systems of five major vendors. This study was part of original work performed under AEC contract for the Directorate of Regulatory Standards. The analysis techniques employed for the safety evaluation of these systems include: Fault Tree Analysis; FMECA (Failure Mode Effects and Criticality Analysis); general system comparisons, contaminant, system control, and design adequacy evaluations; and resultant Off-Site Dose Calculations. The salient areas presented are some of the potential problem areas, the approach that industry has taken to mitigate or design against potential upset conditions, and areas where possible deficiencies still exist. Potential problem areas discussed include hydrogen detonation, hydrogen release to equipment areas, operator/automatic control interface, and needed engineering evaluation to insure safe system operation. Of the systems reviewed, most were in the category of advanced or improved over that commonly in use today, and a conclusion from the study was that these systems offer excellent potential for noble gas control for BWR power plants where more stringent controls may be specified -- now or in the future.

    In the clinic of dermatological surgery, I Department of Dermatology Silesian Medical Academy in Katowice 328 patients were treated surgically for granuloma teleangiectodes in the years 1973-1988. Two methods were used: excision of the lesion and curettage with electrocoagulation of the base of the lesion. After excision the wound was closed by approximation of its margins or local plastic procedure (285 cases) and by covering it with a free full-thickness skin graft (3 cases). Curettage and electrocoagulation was used in 43 cases, mainly due to the location of the lesion (in 90% on fingers). After granuloma excision no recurrences were observed, while after curettage and electrocoagulation recurrences developed in 20% of cases.

    Full Text Available Gaucher disease is the most frequent lysosomal disorder. Its enzyme replacement treatment was the new progress of modern biotechnology, successfully used in the last years. The evaluation of optimal dose of each patient is important due to health and economical reasons. The enzyme replacement is the most expensive treatment. It must be held continuously and without interruption. Since 2001, the enzyme replacement therapy with Cerezyme*Genzyme was formally introduced in Bulgaria, but after some time it was interrupted for 1-2 months. The dose of the patients was not optimal. The aim of our work is to find a mathematical model for quantitative evaluation of ERT of Gaucher disease. The model applies a kind of software called "Statistika 6" via the input of the individual data of 5-year-old children having the Gaucher disease treated with Cerezyme. The output results of the model gave possibilities for quantitative evaluation of the individual trends in the development of the disease of each child and its correlation. On the basis of this results, we might recommend suitable changes in ERT.

    Evaluation of safety culture implementation and socialization results has been perform. Evaluation is carried out with specifying safety culture indicators, namely: Meeting between management and employee, system for incidents analysis, training activities related to improving safety, meeting with regulator, contractors, surveys on behavioural attitudes, and resources allocated to promote safety culture. Evaluation is based on observation and visiting the facilities to show the compliance indicator in term of good practices in the frame of safety culture implementation. For three facilities of research reactors, Kartini Yogyakarta, TRIGA Mark II Bandung and MPR-GAS Serpong, implementation of safety culture is considered good enough and progressive. Furthermore some indicator should be considered more intensive, for example the allocated resources, self assesment based on own questionnaire in the frame of improving the safety culture implementation.

    125 I emits very low energy conversion and Auger electrons. This radionuclide has been used in place of 131 I with the hope of reducing the incidence of post treatment hypothyroidism. 303 of 360 patients treated have been reviewed. Originally very large doses of 125 I were prescribed (751-1,600 μCi/g) but 9 out of 15 patients (60%) became hypothyroid, therefore 4 smaller therapeutic regimes were employed. (1) 55 patients received doses of 200 μCi or less/g thyroid, 69% are euthyroid and 24% hypothyroid after an average of 33 months from treatment. (2) 87 patients received doses of 201-350 μCi/g thyroid, 67% are euthyroid and 21% hypothyroid after an average follow up of 30 months. (3) 70 patients received doses of 351-500 μCi/g thyroid, 77% are euthyroid and 18% hypothyroid 36 months after treatment and (4) 76 patients received doses of 501-750 μCi/g, 41% are euthyroid and 56% hypothyroid 49 months after therapy. No long term complications such as thyroid cancer or leukaemia have occurred but because 125 I does not eliminate or reduce the incidence of post treatment hypothyroidism it probably should not be used in preference to 131 I for the routine treatment of hyperthyroidism

    Radical or extended thymectomy is an effective treatment for myasthenia gravis in the adult population. There are few reports to demonstrate the effectiveness of this treatment in patients with juvenile myasthenia gravis. The main objective of this study was to show that extended transsternal thymectomy is a valid option for treating this disease in paediatric patients. Twenty-three patients with juvenile myasthenia gravis underwent this surgical treatment in the period between April 2003 and April 2014; mean age was 12.13 years and the sample was predominantly female. The main indication for surgery, in 22 patients, was the generalised form of the disease (Osserman stage II) together with no response to 6 months of medical treatment. The histological diagnosis was thymic hyperplasia in 22 patients and thymoma in one patient. There were no deaths and no major complications in the postoperative period. After a mean follow-up period of 58.87 months, 22 patients are taking no medication or need less medication to manage myasthenic symptoms. Extended (radical) transsternal thymectomy is a safe and effective surgical treatment for juvenile myasthenia gravis. Copyright © 2015 Sociedad Española de Neurología.

    Much progress has been made in understanding the main causes of blood culture-negative endocarditis (BCNE). Few studies concerning BCNE treatment (due to previous antibiotics used or fastidious pathogens) are available. We performed this study to evaluate the effectiveness of our therapeutic protocol in BCNE, based on compliance with the protocol, outcome and 1 year mortality. We collected prospectively and analysed retrospectively cases of BCNE between 2002 and 2014, using a simplified and standardized protocol developed by our multidisciplinary team. We apply two kinds of protocols to treat BCNE, which include only four intravenous antimicrobial agents: amoxicillin, vancomycin, gentamicin and amphotericin B. We had 177 patients with definite BCNE. There were 154 (87.0%) patients treated with both appropriate antimicrobial agents and appropriate duration of treatment. We analysed the causes of inappropriate treatment in 13 (7.3%) cases and inappropriate duration in 10 (5.6%) cases. The treatment changes were justified in all cases except one of discharge against medical advice. The fatality rate was 5.1% (nine cases) and all deaths occurred in the group of patients who were treated with appropriate treatment; however, four deaths were not attributable to empirical treatment failure. Concerning the other deaths, the lack of surgical management, in association with empirical treatment, could explain our protocol's failure, such as poorly tolerated surgery. Our protocol is efficient and our mortality rate was low, compared with the literature review. This may result from a strategy that uses a sampling procedure and a standardized protocol at the same time. © The Author 2016.

    Objectives To examine resource use (costs) by women presenting for infertility evaluation and treatment over 18 months, regardless of treatment pursued. Design Prospective cohort study in which women were followed for 18 months. Setting Eight infertility practices. Patients 398 women recruited from infertility practices. Data collection Women completed interviews and questionnaires at baseline, and after 4, 10, and 18 months of follow-up. Medical records were abstracted after 18 months to obtain details of services used. Main outcome measures Per-person and per-successful-outcome costs Results Treatment groups were defined as highest intensity treatment use. 20% of women did not pursue cycle-based treatment; about half pursued in-vitro fertilization (IVF). Median per-person costs ranged from $1,182 for medications only, to $24,373 and $38,015 for IVF and IVF-donor egg groups, respectively. Estimates of costs of successful outcomes (delivery or ongoing pregnancy by 18 months) were higher – $61,377 for IVF, for example – reflecting treatment success rates. Within the timeframe of the study, costs were not significantly different for women who were successful and women who were not. Conclusions While individual patient costs vary, these cost estimates developed from actual patient treatment experiences may provide patients with realistic estimates to consider when initiating infertility treatment.

    The COMBINE (combined pharmacotherapies and behavioral intervention) clinical trial recently evaluated the efficacy of pharmacotherapies, behavioral therapies, and their combinations for the treatment of alcohol dependence. Previously, the cost and cost-effectiveness of COMBINE have been studied. Policy makers, patients, and nonalcohol-dependent individuals may be concerned not only with alcohol treatment costs but also with the effect of alcohol interventions on broader social costs and outcomes. To estimate the sum of treatment costs plus the costs of health care utilization, arrests, and motor vehicle accidents for the 9 treatments in COMBINE 3 years postrandomization. A cost study based on a randomized controlled clinical trial. : The study involved 786 participants 3 years postrandomization. Multivariate results show no significant differences in mean costs between any of the treatment arms as compared with medical management (MM) + placebo for the 3-year postrandomization sample. The median costs of MM + acamprosate, MM + naltrexone, MM + acamprosate + naltrexone, and MM + acamprosate + combined behavioral intervention were significantly lower than the median cost for MM + placebo. The results show that social cost savings are generated relative to MM + placebo by 3 years postrandomization, and the magnitude of these cost savings is greater than the costs of the COMBINE treatment received 3 years prior. Our study suggests that several alcohol treatments may indeed lead to reduced median social costs associated with health care, arrests, and motor vehicle accidents.

    Abstract Lymphoedema is a debilitating condition, manifesting in excess lymphatic fluid and swelling of subcutaneous tissues. Lymphoedema is as of yet still an incurable condition and current treatment modalities are not satisfactory. The capacity of mesenchymal stem cells to promote angiogenesis......, secrete growth factors, regulate the inflammatory process, and differentiate into multiple cell types make them a potential ideal therapy for lymphoedema. Adipose tissue is the richest and most accessible source of mesenchymal stem cells and they can be harvested, isolated, and used for therapy...... in a single stage procedure as an autologous treatment. The aim of this paper was to review all studies using mesenchymal stem cells for lymphoedema treatment with a special focus on the potential use of adipose-derived stem cells. A systematic search was performed and five preclinical and two clinical...

    Benign prostatic hyperplasia (BPH) can significantly impair quality of life in older men. Most men over 60 experience some symptoms due to BPH and it is thought that essentially all men would eventually be affected by it if they lived long enough. At present, transurethral resection of the prostate (TURP), a surgical treatment for BPH, is one of the more common procedures performed in the developed world, particularly in the United States. A number of other treatments are also often used, including open prostatectomy, side-firing lasers, and drug therapy. With the population in the developed world rapidly aging, BPH is expected to affect an even larger group of men in the future. Current methods of therapy carry significant disadvantages. Open prostatectomy carries a fairly high risk of impotence and incontinence, as well as sometimes significant risk of death depending on the patient's age and medical conditions. TURP also carries similar risks, albeit reduced, including the risk of substantial blood loss and a small but meaningful risk of death. Side-firing lasers are thought to have a reduced risk of death compared to TURP due to significantly reduced bleeding; however, patients often experience an extended period of pain during voiding due to prolonged tissue sloughing. Drug treatment, although useful for some patients, does not strongly improve symptoms in the majority of patients. Even with the current range of treatments, many patients with symptomatic BPH elect to avoid any current treatment due to risks and side effects. As a possible solution to this problem, previous writers have suggested the possibility of treating BPH through interstitial thermotherapy. In this treatment, prostatic tissue is heated from within the prostate to the point of irreversible necrosis. Healing processes then reduce the volume of the affected tissue, even in the absence of sloughing. This study covers initial human use of such a device, using an 810 nm wavelength diode laser

    Full Text Available OBJECTIVE: For a cohort of patients with congenital mitral stenosis (CMS, to determine: patient outcomes, predictors of valve repairability and predictors of durability of valve repair. METHODS: From 1989 and 2002, 23 patients underwent surgical treatment of CMS, excluding those with common atrioventricular canal, and univentricular forms. The median age at operation was 15.5 months (range 2-204, and the median body weight was 11 Kg (range 4.5-51.6. Seventeen patients (73.9% had associated anomalies, including Shone's complex in nine (39.1% and pulmonary hypertension in 14 (60.9%. Mitral stenosis was severe in 14 patients (60.9% and moderate in the remaining (median trans-mitral gradient of 16 mmHg, range 8.5-32. Mitral valve repair was performed in 18 patients (78.3%, and valve replacement in five (21.7%. Repair techniques included papillary muscle splitting (n=10, excision of supravalvular ring (n=9 and commissurotomy (n=8. Twelve patients (52.2% required associated procedures. RESULTS: There were no early and late deaths at a mean follow-up of 58.5 ± 46.7 months (range 1-156. Mean hospital stay was 12.7 ± 8.2 days. There were no significant factors associated with unsuccessful valve repair. Actuarial freedom from reoperation at five years was 67.1% (CI 95%: 56.8% to 77.4%. The mitral valve repair group required reoperation in eight patients (44.4% (two early and six late, as opposed to one (20% in the replacement group. The presence of preoperative pulmonary hypertension was significantly related (p<0.005 to higher reoperation rates. All but two the followed patients are presently in functional class I and the echocardiography has shown less than 2+ mitral stenosis and/or regurgitation. CONCLUSION: Reoperations were the most important cause of morbidity at the medium-term follow-up of CMS. Preoperative pulmonary hypertension may predict the need for reoperation after mitral valve repair, which is the procedure of choice in CMS.

    Full Text Available Objective To formulate the best treatment plan for Alzheimer's disease patients by evaluating the therapeutic efficacy and side effect of various evidence-based programs. Methods Alzheimer's disease, donepezil, rivastigmine, galantamine, memantine, rosiglitazone, etc. were defined as retrieval words. PubMed, Cochrane Library, Wanfang Data and China National Knowledge Infrastructure (CNKI databases were used with applying of manual searching. Systematic reviews, randomized controlled trials (RCT, controlled clinical trials and case-observation studies were collected and evaluated by Jadad Scale. Results After screening, 33 selected resources included 14 systematic reviews, 14 randomized controlled trials, 4 controlled clinical trials and 1 case-observation study. According to Jadad Scale, total 28 articles were evaluated to be high quality (12 with score 4, 10 score 5, 6 score 7, and 5 were low quality with score 3. It was summarized as follows: 1 Alzheimer's disease is a progressive neurodegenerative disease for which no cure exists. To date, only symptomatic treatments with cholinesterase inhibitors (donepezil, rivastigmine, galantamine and an N-methyl-D-aspartate (NMDA receptor noncompetitive antagonist (memantine, are effective and well tolerated to counterbalance the neurotransmitter disturbance, but cannot limit or impact on disease progression. 2 Disease modifying drug is an potential agent, with persistent effect on slowing the progression of structural damage, and can be detected even after withdrawing the treatment. Many types of disease modifying drugs are undergoing clinical trials. Conclusions Using evidence-based medicine methods can provide best clinical evidence on Alzheimer's disease treatment. doi: 10.3969/j.issn.1672-6731.2014.03.009

    Tests carried out (1973 and 1974) at the Chair of Gardening, VKHIA, Plovdiv, were aimed at producing stimulative effects through irradiation of vegetable seeds. Treatment with 2000 R enhanced the ripening of the early tomato variety Pioneer 2 by 18.6% and its overall yield by 14.0% on a two year mean, while the same treatment of Triumph variety proved ineffective. Kourtovska Kapiya pepper variety did not positively respond to gamma-rays irradiation with 1200 R. Irradiation with 2000 R raised the earliness of Bulgarski 12 eggplant variety by 10.8% and the yield by 6.0%.

    Full Text Available Background. No strongly clinical evidence about the use of hand robot-assisted therapy in stroke patients was demonstrated. This preliminary observer study was aimed at evaluating the efficacy of intensive robot-assisted therapy in hand function recovery, in the early phase after a stroke onset. Methods. Seven acute ischemic stroke patients at their first-ever stroke were enrolled. Treatment was performed using Amadeo robotic system (Tyromotion GmbH Graz, Austria. Each participant received, in addition to inpatients standard rehabilitative treatment, 20 sessions of robotic treatment for 4 consecutive weeks (5 days/week. Each session lasted for 40 minutes. The exercises were carried out as follows: passive modality (5 minutes, passive/plus modality (5 minutes, assisted therapy (10 minutes, and balloon (10 minutes. The following impairment and functional evaluations, Fugl-Meyer Scale (FM, Medical Research Council Scale for Muscle Strength (hand flexor and extensor muscles (MRC, Motricity Index (MI, and modified Ashworth Scale for wrist and hand muscles (AS, were performed at the beginning (T0, after 10 sessions (T1, and at the end of the treatment (T2. The strength hand flexion and extension performed by Robot were assessed at T0 and T2. The Barthel Index and COMP (performance and satisfaction subscale were assessed at T0 and T2. Results. Clinical improvements were found in all patients. No dropouts were recorded during the treatment and all subjects fulfilled the protocol. Evidence of a significant improvement was demonstrated by the Friedman test for the MRC (P<0.0123. Evidence of an improvement was demonstrated for AS, FM, and MI. Conclusions. This original rehabilitation treatment could contribute to increase the hand motor recovery in acute stroke patients. The simplicity of the treatment, the lack of side effects, and the first positive results in acute stroke patients support the recommendations to extend the clinical trial of this

    This report documents CH2M HILL Hanford Group Inc. (CH2M HILL) 2007 dryer testing results in Richland, WA at the AMEC Nuclear Ltd., GeoMelt Division (AMEC) Horn Rapids Test Site. It provides a discussion of scope and results to qualify the dryer system as a viable unit-operation in the continuing evaluation of the bulk vitrification process. A 10,000 liter (L) dryer/mixer was tested for supplemental treatment of Hanford tank low-activity wastes, drying and mixing a simulated non-radioactive salt solution with glass forming minerals. Testing validated the full scale equipment for producing dried product similar to smaller scale tests, and qualified the dryer system for a subsequent integrated dryer/vitrification test using the same simulant and glass formers. The dryer system is planned for installation at the Hanford tank farms to dry/mix radioactive waste for final treatment evaluation of the supplemental bulk vitrification process

    Clinical case reports and prospective trials have demonstrated a reproducible benefit of hypothalamic-pituitary-adrenal (HPA) axis modulation on the rate of recovery from acute inflammatory central nervous system (CNS) demyelination. As a result, corticosteroid preparations and adrenocorticotrophic hormones are the current mainstays of therapy for the treatment of acute optic neuritis (AON) and acute demyelination in multiple sclerosis.Despite facilitating the pace of recovery, HPA axis modulation and corticosteroids have failed to demonstrate long-term benefit on functional recovery. After AON, patients frequently report visual problems, motion perception difficulties and abnormal depth perception despite 'normal' (20/20) vision. In light of this disparity, the efficacy of these and other therapies for acute demyelination require re-evaluation using modern, high-precision paraclinical tools capable of monitoring tissue injury.In no arena is this more amenable than AON, where a new array of tools in retinal imaging and electrophysiology has advanced our ability to measure the anatomic and functional consequences of optic nerve injury. As a result, AON provides a unique clinical model for evaluating the treatment response of the derivative elements of acute inflammatory CNS injury: demyelination, axonal injury and neuronal degeneration.In this article, we examine current thinking on the mechanisms of immune injury in AON, discuss novel technologies for the assessment of optic nerve structure and function, and assess current and future treatment modalities. The primary aim is to develop a framework for rigorously evaluating interventions in AON and to assess their ability to preserve tissue architecture, re-establish normal physiology and restore optimal neurological function.

    From 1973 to 1979, at the Institute of Oncology and Radiobiology, Havana City, 91 adults were irradiated because they underwent no Hodgkin's lymphomas at Stage I (located) and Stage II (regional extension) to whom radiant treatment was the basic therapeutic selection, with single or multiple fields and dose ranging between 3 500 and 4 000 rads-tumor, and some of them at Stage III, where primary treatment was chemotherapy. Present survival for all of them after 3 and 5 years is 55.7% and 54.7%, with 84.4% for patients at Stage I, 55.8% and 52.4% for Stage II and 33.8% for Stage III. Survival was similar for both sexes; in the same way ganglionar processes and those of extraganglionar localization presented no significant survival differences. Only to 7 patients (7.7%) modular forms were diagnosed. (author)

    Full Text Available Background . Hypertension is a civilization disease which currently affects about 10.5 m people in Poland. The number of patients with diagnosed, untreated hypertension amounts to 18%, and as many as 45% of patients are treated ineffectively whereas only 26% are treated effectively. Impedance cardiography (IC is an important tool both in diagnostics and the treatment of hypertensive patients, particularly in the case of antihypertensive treatment resistance. This method allows for the individualized treatment of each patient on the basis of hemodynamic parameters, monitoring of hypertensive patients in the outpatient care setting, and the assessment of cardiovascular risk factors. Objectives . The aim of the study was to evaluate the efficacy of hypotensive medications in patients with hypertension using impedance cardiography. Material and methods. The study involved 60 hypertensive patients, treated with antihypertensives, who failed to achieve the required blood pressure values. The modification of hypertension therapy was based on EBM (evidence-based medicine and on hemodynamic parameters obtained using impedance cardiography. Results . It was found that high blood pressure therapy based on impedance cardiography parameters has a significant influence on blood pressure reduction compared to EM B-based therapy: below 140/90: 66.8 vs. 55.1% and below 130/80: 23.5 vs. 18.9%. Conclusions . On the basis of this study it was confirmed that impedance cardiography allows for a significant reduction of hypertension and the selection of the most effective therapeutic strategy, providing for the optimization and efficacy of hypertension treatment.

    1987-01-01

    Between April 1984 and December 1985 we treated ten children suffering from neuroblastoma in a total of 25 metaiodobenzylguanidine (MIBG) courses. Five had had a relapse of neuroblastoma stage III or IV, three had never achieved a remission in spite of intensive chemotherapy, and two were treated with an unstable remission. The children were each administered from 1 to 5 courses with a dosage per course of between 1295 and 9065 MBq. The sum of the single doses during the whole course of therapy ranged between 3145 and 21,904 MBq per child. Five of five children suffering from bone pain and fever became free of complaints during the first three treatment days. Six of eight children with manifest tumor at onset of therapy responded well to the treatment: response extended from transitory decrease in elevated catecholamine levels in serum and urine to complete disappearance of large abdominal tumor masses. We also observed a decrease in bone marrow involvement and a stabilization of osteolytic lesions. Seven of these eight children died in spite of a good response from 55 to 350 days after the first MIBG treatment course. The only side effect we witnessed was a reversible bone marrow depression. In three children we combined the MIBG therapy with bone marrow transplantation

    Purpose: The aim of this pharmaco-epidemiological study was to evaluate the prevalence of oropharyngeal candidiasis (OPC) in cancer patients treated with chemotherapy and/or radiotherapy. Methods and Materials: Signs and symptoms of OPC were noted for all patients. Antifungal therapeutic management was recorded in OPC patients. Patients receiving local antifungal treatments were monitored until the end of treatment. Results: Enrolled in the study were 2,042 patients with solid tumor and/or lymphoma treated with chemotherapy and/or another systemic cancer treatment and/or radiotherapy. The overall prevalence of OPC was 9.6% (95% confidence interval, 8.4%-11.0%] in this population. It was most frequent in patients treated with combined chemoradiotherapy (22.0%) or with more than two cytotoxic agents (16.9%). Local antifungal treatments were prescribed in 75.0% of OPC patients as recommended by guidelines. The compliance to treatment was higher in patients receiving once-daily miconazole mucoadhesive buccal tablet (MBT; 88.2%) than in those treated with several daily mouthwashes of amphotericin B (40%) or nystatin (18.8%). Conclusion: OPC prevalence in treated cancer patients was high. Local treatments were usually prescribed as per guidelines. Compliance to local treatments was better with once-daily drugs.

    The need of a reference value for the composition of materials distributed in intercomparisons is generally recognized. A single reference laboratory or a group of reference laboratories may be used to establish this reference value. The respective advantages and limitations of the two approaches are discussed. The reference measurements must be evaluated to provide the confidence limits of the reference value but also an estimate of the possible heterogeneity of the materials and its samples. The results of the intercomparison measurements should themselves be evaluated to test and discuss the significance of the biases of individual and selected groups of laboratories or techniques. The approach taken by the Analytical Quality Control Services of the International Atomic Energy Agency is illustrated by the SR-1 intercomparison on uranium assay in UO 2 powder

    Full Text Available OBJECTIVE: To evaluate the correlation between kyphosis due to burst fractures of thoracic and lumbar spine and clinical outcome in patients undergoing conservative or surgical treatment.METHODS: A retrospective, cross-sectional study was conducted with 29 patients with thoracolumbar burst fractures treated by the Spine Group in a trauma reference hospital between the years 2002 and 2011. Patients were followed-up as outpatients for a minimum of 24 months. All cases were clinically evaluated by Oswestry and SF-36 quality of life questionnaires and the visual analogue scale (VAS of pain. They were also evaluated by X-ray examinations and CT scans of the lumbosacral spine at the time of hospitalization and subsequently as outpatients by Cobb method for measuring the degree of kyphosis.RESULTS: There was no statistically significant correlation between the degree of initial kyphosis and clinical outcome measured by VAS and by most of the SF-36 domains in both patients treated conservatively and the surgically treated. The Oswestry questionnaire showed benefits for patients who received conservative treatment (p=0.047 compared to those surgically treated (p=0.335. The analysis of difference between initial and final kyphosis and final kyphosis alone in relation to clinical outcome showed no statistical correlation in any of the scores used.CONCLUSION: The clinical outcome of treatment of the thoracic and lumbar burst fractures was not influenced by a greater or lesser degree of initial or residual kyphosis, regardless of the type of treatment.

    After two surveys for indoor air pollutants (radon and other chemicals) the homeowners were surveyed for their reactions. The results of these participant evaluation surveys, assuming that the participants that responded to the survey were representative, indicate that homeowners will accept a significant level of monitoring activity as part of an indoor air quality field study. Those participants completing surveys overwhelmingly enjoyed being in the studies and would do it again. We believe that the emphasis placed on positive homeowner interactions and efforts made to inform participants throughout our studies were positive factors in this result. There was no substantial differences noted in the responses between the 70-house study, which included a homeowner compensation payment of $100, and the 300-house study, which did not include a compensation payment. These results provide encouragement to conduct future complex, multipollutant indoor air quality studies when they are scientifically sound and cost effective

    The evaluation of forensic evidence can occur at any level within the hierarchy of propositions depending on the question being asked and the amount and type of information that is taken into account within the evaluation. Commonly DNA evidence is reported given propositions that deal with the sub-source level in the hierarchy, which deals only with the possibility that a nominated individual is a source of DNA in a trace (or contributor to the DNA in the case of a mixed DNA trace). We explore the use of information obtained from examinations, presumptive and discriminating tests for body fluids, DNA concentrations and some case circumstances within a Bayesian network in order to provide assistance to the Courts that have to consider propositions at source level. We use a scenario in which the presence of blood is of interest as an exemplar and consider how DNA profiling results and the potential for laboratory error can be taken into account. We finish with examples of how the results of these reports could be presented in court using either numerical values or verbal descriptions of the results. Copyright © 2015 Elsevier Ireland Ltd.

    Full Text Available Abstract Background Physical Activity Across the Curriculum (PAAC is a 3-year elementary school-based intervention to determine if increased amounts of moderate intensity physical activity performed in the classroom will diminish gains in body mass index (BMI. It is a cluster-randomized, controlled trial, involving 4905 children (2505 intervention, 2400 control. Methods We collected both qualitative and quantitative process evaluation data from 24 schools (14 intervention and 10 control, which included tracking teacher training issues, challenges and barriers to effective implementation of PAAC lessons, initial and continual use of program specified activities, and potential competing factors, which might contaminate or lessen program effects. Results Overall teacher attendance at training sessions showed exceptional reach. Teachers incorporated active lessons on most days, resulting in significantly greater student physical activity levels compared to controls (p Conclusion In the first year of the PAAC intervention, process evaluation results were instrumental in identifying successes and challenges faced by teachers when trying to modify existing academic lessons to incorporate physical activity.

    The CyberKnife, a medical device for stereotactic radiotherapy, is composed of a combination of a robot manipulator and LINAC. For the treatment of head and neck tumors, this system has been applied. Between June 2000 and January 2001, 18 patients with head and neck tumor were treated with this system because of tumor recurrence, difficulty in surgery or additional increase after external radiotherapy. The median age was 64 years. Primary lesions were skull base (4), nasopharynx (3), paranasal sinus (3), nasal cavity (2), lacrimal gland (1), oropharynx (1), oral floor (1), and buccul mucosa (1), metastatic lymph nodes were found in three. The prescribed dose was 12-38 Gy as for marginal dose. The response rate (CR+PR) was 44.4% and local control rate (CR+PR+NC) was 77.8%. The adverse effects were assessed by the NCI-CTC Version 2.0 and observed grade 3 in two cases. Our early experience indicates that this system could to be feasible for the treatment of locally advanced or recurrent head and neck tumor, and for the reduction of adverse effect and maintenance of useful QOL of patients.

    Basic principles in the therapy of chronic idiopathic thrombocytopenic purpura are glucocorticoides and splenectomy. Other measures: Intravenous high doses gamma globulin therapy, attenuated androgenes, immunosupresive drugs and plasmaferesis are less effective. During the period of 1989-1992 we treated 34 patients. From 34 patients, 23 were women and 11 were men. We treated patients primarily by prednisolon approximaly for 2 - 4 weeks. Rarely we use doses of 3 mg/kg per day for short periods of time (5 to 10 days) or "pulse therapy" of 500 mg per day. Those doses may be effective in elevating platelet count if the response is poor. If response occurs, high dosages of steroides should be tareped to determine the amount that will maintain the platelet count in the range of 30x10(9)/l to 50x10(9)/l (to minimaze the toxic sade effects of steroides). If steroides are ineffective, we perform splenectomy. From 34 treated patients by glucocorticoides, in 16 we got remission and in 11 partial response. We discussed in detailes relationship duration of treatment with glucocorticoides and level of platelets, and also correlation duration of treatment with prognosis. From 6 splenectomized patients 3 were successful. In two patients we applied intravenous gamma globulin therapy and attenuated androgen successfuly. In one patients therapy with gamma globulin, immunosupresive drugs, androgen and other measures was ineffective. In one patients without splenectomy we administrated successfuly gamma globulin therapy and androgen for peroid of two years.

    1981-01-01

    Thirty-one children under the age of 15 years with verified medulloblastoma were treated at Addenbrookes Hospital from 1940 to 1976. In addition to surgical treatment, all received high dose irradiation to the whole neuraxis. Nine were still alive in 1979, of whom eight were examined. All these patients showed some residual problems, but five were leading active lives and had only minor physical disability. There was evidence of disturbance in growth, with shortening of the spine in relation to the limbs, in all the children. The height centile was lower than expected from parental height in four and one was severely dwarfed. Growth hormone secretion in response to exercise was, however, normal in five of six patients tested. Three children also showed failure of growth of the jaw sufficiently severe to be a cosmetic problem. Frank mental retardation was present in three children. A raised resting TSH level was found in two children, one of whom had a multinodular goiter. Of the three children with severe problems, two had been treated when under two years of age. Long-term follow-up of children who survive medulloblastoma is clearly necessary and consideration should perhaps be given to revision of current treatment regimes in very young children

    Research and analysis of the following aspects of rehabilitation have been conducted at the Rum Jungle mine site over the past three years: drainage structure stability; rock batter stability; soil fauna; tree growth in compacted soils; rehabilitation costs. The results show that, for future rehabilitation projects adopting refined methods, attention to final construction detail and biospheric influences is most important. The mine site offers a unique opportunity to evaluate the success of a variety of rehabilitation methods to the benefit of the industry in Australia overseas. It is intended that practical, economic, research will continue for some considerable time

    Skin laxity, wrinkles and cellulite are common aesthetic problems associated with the aging process. These symptoms are due to the weakening and thinning of dermal connective tissue and the enlargement of hypodermal fat cells. The aim of this study was to evaluate the safety and efficacy of the TriPollar RF technology in reducing fat and collagen regeneration. Twelve healthy patients underwent weekly treatments on different body sites using the TriPollar technology. Treatment areas were photographed and measured and patient satisfaction was monitored. One abdominal patient consented to a series of TriPollar treatments prior to her scheduled abdominoplasty. A controlled histopathology analysis was performed on skin samples taken during the abdominoplasty procedure. Histopathological examination revealed marked differences between treated and non-treated abdominal skin areas. An increase of 49% in dermal thickness, focal thickening of collagen fibers and focal shrinkage of fat cells was shown following TriPollar treatments. Average patient satisfaction indicated clear satisfaction with the clinical results achieved. The TriPollar is a safe and effective non-invasive technology leading to skin tightening and body shaping. Histology results indicate changes at the dermal and fat layers following TriPollar treatments resulting in increased collagen regeneration and stimulated fat metabolism.

    Blood pressure (BP) may be high during usual daily life in one out of 7-8 individuals with normal BP in the clinic or doctor's office. This condition is usually defined as masked hypertension (MH). Prevalence of MH varied across different studies depending on patient characteristics, populations studied, and different definitions of MH. Self-measured BP and ambulatory BP (ABP) have been widely used to identify subjects with MH. Various factors have been identified as possible determinants of MH. Cigarette smoking, alcohol, physical activity, job, and psychological stress may increase BP out of the clinical environment in otherwise normotensive individuals, leading to MH. In most studies, target organ damage was comparable in subjects with MH and those with sustained hypertension, and greater than in those with true normotension. Subjects with MH showed a 1.5- to 3-fold higher risk of major cardiovascular (CV) disease than those with normotension, and their risk was not different from that of patients with sustained hypertension. In an overview of literature, we found that the risk of major CV disease was higher in subjects with MH than in the normotensive subjects regardless of the definition of MH based on self-measured BP (hazard ratio (HR) 2.13; 95% confidence interval (CI): 1.35-3.35; P = 0.001) or 24-h ABP (HR 2.00; 95% CI: 1.54-2.60; P who appear to be more likely to have this condition. Antihypertensive treatment is envisaged in these subjects, although the associated outcome benefits are still undetermined.

  5. Anismus: the cause of constipation? Results of investigation and treatment.

    Duthie, G S; Bartolo, D C

    1992-01-01

    Anismus, or failure of the somatic sphincter apparatus to relax at defecation, has been implicated as a major contributor to the problem of obstructed defecation. Current diagnostic methods depend on laboratory measurements of attempted defecation and the most complex, dynamic proctography has been the mainstay of diagnosis. Using a new computerized ambulatory method of recording sphincter function in these patients at home, we report an 80% reduction in our diagnostic rate suggesting that conventional tests fail to accurately diagnose this condition, probably because they poorly represent the natural physiology of defecation. Treatment of this distressing condition is more complex and a variety of surgical and pharmacological measures have failed. Biofeedback retraining of anorectal function of these patients has been very successful and represents the management of choice.

    Full Text Available PURPOSE: To show platelet rich plasma (PRP application of chronic skin wounds and to evaluate the results from the treatment. MATERIAL AND METHODS: A total of 14 patients with problematic skin wounds had been treated at the clinic for a period of five years (from May 2009 to December 2014 with the following patient sex ratio: male patients - 5 and female patients - 9. Average age - 48,5 (30-76. Patients with Type 2 Diabetes - 4, with decubitus ulcers - 6, traumatic - 8, with infection - 5. Based on a scheme developed by us, all cases were treated by administering platelet-rich plasma, derived by PRGF Endoret system. Follow-up period was within 4 - 6 months (4,5 on average. RESULTS: The results have been evaluated based on the following functional scoring systems - Total wound score, Total anatomic score and Total score (20. The baseline values at the very beginning of the follow-up period were as follows: Total wound score - 12 p.; Total anatomic score - 10 p., Total score - 17 p. By the end of the treatment period the score was 0 p., which means excellent results, i.e. complete healing of the wounds. CONCLUSION: We believe that the application of PRP may become optimal therapy in the treatment of difficult to heal wounds around joints, bone, subject tendons, plantar surface of the foot, etc., as it opens new perspectives in the field of human tissue regeneration.

  7. A European neutron dosimetry intercomparison project (ENDIP). Results and evaluation

    1978-01-01

    A total of twenty groups from nine countries participated in sessions of the European Neutron Dosimetry Intercomparison Project (ENDIP) which were held during 1975 at GSF, Munich-Neuherberg and TNO, Rijswijk. The data of all participants are collected, the analysis and evaluation of the results are given in the present report. Specific chapters deal with the experimental arrangements and monitoring results at GSF and TNO, characteristics of the dosimetry systems employed by the paticipating groups and the basic physical data and correction factors employed for the determination of kerma and absorbed dose. In general, the participants in ENDIP quote systematic uncertainties of 7 to 8% in the neutron and total kerma or absorbed dose, which are mainly attributed to inadequate knowledge of basic constants. The variations in the results obtained by different participants seem to be in accordance with the relative large systematic uncertainties quoted. In order to determine the influence of the use of different values for the physical parameters, the relative responses of the participants' dosimeters have also been compared. The variances of quoted kerma and dose values are of the same order of magnitude as those of instrument responses. This result indicates inconsistencies in experimental techniques employed by the participants for the determination of kerma and absorbed dose. A separate nonparametric analysis of the ENDIP results confirmed that there are considerable systematic differences. Recommendations for future studies on neutron dosimetry for biological and medical applications are given at the end of the report

  8. Using 'payment by results' to fund the treatment of dependent drug users--proceed with care!

    2011-10-01

    The UK government is changing its system of payment for drug treatment services in order to reward the achievement of better patient outcomes. This is a model that may be taken up internationally. This 'payment by results' funding system will reward providers for achieving good outcomes in terms of whether clients are drug free, employed and/or not convicted of a criminal offence. Providers will also receive a payment based on health and wellbeing outcome measurement. The definition and measurement of success in achieving these outcomes is complex and challenging, as is the need to bridge treatment costs during the period in which outcomes are pursued. This experiment requires careful evaluation if the delivery of drug treatment is not to be jeopardized or fragmented. © 2011 The Authors, Addiction © 2011 Society for the Study of Addiction.

  11. Economic evaluation of radiation processing in urban solid wastes treatment

    Carassiti, F.; Lacquaniti, L.; Liuzzo, G.

    During the last few years, quite a number of studies have been done, or are still in course, on disinfection of urban liquid wastes by means of ionizing radiations. The experience gained by SANDIA pilot plant of irradiation on dried sewage sludge, together with the recently presented conceptual design of another plant handling granular solids, characterized by high efficiency and simple running, have shown the possibility of extending this process to the treatment of urban solid wastes. As a matter of fact, the problems connected to the pathogenic aspects of sludge handling are often similar to those met during the disposal of urban solid wastes. This is even more so in the case of their reuse in agriculture and zootechny. The present paper introduces the results of an analysis carried out in order to evaluate the economical advantage of inserting irradiation treatment in some process scheme for management of urban solid wastes. Taking as an example a comprehensive pattern of urban solid wastes management which has been analysed and estimated economically in previous works, we first evaluated the extra capital and operational costs due to the irradiation and then analysed economical justification, taking into account the increasing commercial value of the by-products.

    In-patient treatment of patients with chronic tinnitus is necessary only when these patients have a severe psychosomatic co-morbidity and suffer severely. However this therapeutic approach has to be supervised and evaluated properly. We present data and results of 1841 patients suffering from chronic tinnitus. Due to the severity of the symptom and psycho-neurotic side effects in-patient treatment was necessary. Therapy lasted 5 - 6 weeks, the main aspect was an intensive psychotherapeutic evaluation and stabilisation next to retraining and habituation programmes. Relaxation techniques were taught. Patients suffered from their tinnitus more than six month; 95 % further suffered from hearing-loss, mainly in high frequencies. The study evaluates results of patients from October 1994 until June 2000. Basis of the study was the evaluation of a specific tinnitus-questionnaire (TQ), published by Hallam in the UK and translated by Goebel and Hiller in Germany. Data was recorded at registration in our clinic, 4 - 6 months later during admission and at the end of the therapy. Final data was gained during a special meeting or questioning 6 months after dismissal from the clinic. Patients that suffered most showed the greatest improvement; directly after therapy there was a highly significant improvement in the TQ for an average of 13.01 points. Highly significant improvements were found in all the TQ-subscales respectively. Only 10 % of the patients did not show any improvement at all. Therapy of most severe cases of chronic tinnitus is possible, using an integrated concept of otologic and psychosomatic treatments. With large numbers of patients and sufficient data a thorough and necessary evaluation of this therapy can be achieved.

  14. Developing a dependable approach for evaluating waste treatment data

    International Nuclear Information System (INIS)

    Gering, K.L.

    1997-01-01

    Decision makers involved with hazardous waste treatment issues are faced with the challenge of making objective evaluations concerning treatment formulations. This work utilizes an effectiveness factor (denoted as η) as the basis for waste treatment evaluations, which was recently developed for application to mixed waste treatability studies involving solidification and stabilization at the Idaho National Engineering and Environmental Laboratory. The effectiveness factor incorporates an arbitrary treatment criterion Φ, which in practice could be the Toxicity Characteristic Leaching Procedure, Unconfined Compressive Strength, Leachability Index, or any other criterion used to judge treatment performance. Three values for Φ are utilized when assessing a given treatment formulation: before treatment, after treatment, and a reference value (typically a treatment standard). The expression for η also incorporates the waste loading as the prime experimental parameter, and accounts for the contribution that each hazard has upon the overall treatment performance. Also discussed are general guidelines for numerical boundaries and statistical interpretations of treatment data. Case studies are presented that demonstrate the usefulness of the effectiveness factor and related numerical methods, where the typical hazards encountered are toxic metals within mixed waste

    Full Text Available We risk ignoring cheaper and safer medical treatments because they cannot be patented, lack profit potential, require too much patient-contact time, or do not have scientific results. Novel medical treatments may be difficult to evaluate for a variety of reasons such as patient selection bias, the effect of the package of care, or the lack of identifying the active elements of treatment. Whole Systems Research (WSR is an approach designed to assess the performance of complete packages of clinical management. While the WSR method is compelling, there is no standard procedure for WSR, and its implementation may be intimidating. The truth is that WSR methodological tools are neither new nor complicated. There are two sequential steps, or boxes, that guide WSR methodology: establishing system predictability, followed by an audit of system element effectiveness. We describe the implementation of WSR with a particular attention to threats to validity (Shadish, Cook, & Campbell, 2002; Shadish & Heinsman, 1997. DOI: 10.2458/azu_jmmss.v2i1.12365

    1989-01-01

    In a series of 103 cases of postirradiation lesions of the brachial plexus operated on between 1978 and 1986--of which 60 patients have been reviewed with a follow up from 2 to 9 years--the surgical results are analyzed according to an anatomic classification, a clinical classification, and the surgical procedures. We conclude that the radiation plexitis should be treated surgically and at the earliest possible time after the onset of paresthesias. Also, the surgical procedure which gives the best results is neurolysis with pedicled omentoplasty

    From Nov. 1983 through Jan. 1986, 43 patients with nonsmall cell lung cancer were treated by radiation therapy at Inje Medical College Paik Hospital. 38 patients were available for the analysis of this study. 33 patients received definite irradiation with curative intent, while 5 patients received postoperative irradiation. Chemotherapy was added in 12 patients before, during and after radio-therapy. 28 patients were squamous cell carcinoma and 10 patients were adenocarcinoma. There were 29 men and 9 women (median age, 58 years; range 34 to 74 years). Stage I was 1 patient, Stage 11, 7 patient, and Stage 111, 30 patients. Among 33 patients who received radiotherapy with curative intent, follow up radiological study revealed complete response in 12 patients (36%), partial response, in 9 patients (27%), and minimal response, in 5 patients (15%), while 7 patients (21%) were nonresponders. Median survival for all patients was 6.9 months; squamous cell carcinoma, 7.3 months, adenocarcinoma, 5.9 months. Responders survived median 7 months, while nonresponders survived median 1.9 months. Improved complete response rate and survival were shown in high radiation dose group. As prognostic factors, age, initial performance status, sex, histology and tumor location were evaluated

    Full Text Available A set of most acceptable and well-known methods of dust intensity evaluation has been defined and tested (dependence of Westphal D. L. et al. and DEAD scheme based on the analysis of exiting approaches (deserts, tailing dumps, etc.. The description of the chosen methods has been given. The determination of dynamic velocity u* and velocity at the height of +10 m above the dusting surface u10 which are necessary to evaluate the dust intensity has been demonstrated. The method is based on two-dimensional numerical model of atmosphere aerodynamics in the area of "tailing dumps of ANOF-2 ‒ the town of Apatity". The study provides calculations of horizontal velocity at the height of +10 m above the dusting surface at the wind speed varying from 5 to 23 m/sec. The work also suggests the results of graphical data processing related to tailing grain size distribution from the surface of the firmly established surface of the tailing dumps of ANOF-2. Comparative analysis has been given and the peculiarities of interval (based on grains sizes dust intensity of the tailing dumps of ANOF-2 have been shown using the dependence of Westphal D. L. et al. and DEAD scheme within the wind speed range. The received values of dust intensity at the lower range limit are close to the "maximum specific dust off" value which is used by project specialists for documentation development

    This document is an engineering study of spent ion exchange resin treatment processes with the purpose of identifying one or more suitable treatment technologies. Classifications of waste considered include all classes of low-level waste (LLW), mixed LLW, transuranic (TRU) waste, and mixed TRU waste. A total of 29 process alternatives have been evaluated. Evaluation parameters have included economic parameters (both total life-cycle costs and capital costs), demonstrated operability, environmental permitting, operational availability, waste volume reduction, programmatic consistency, and multiple utilization. The results of this study suggest that there are a number of alternative process configurations that are suitable for the treatment of spent ion exchange resin. The determinative evaluation parameters were economic variables (total life-cycle cost or capital cost) and waste volume reduction. Immobilization processes are generally poor in volume reduction. Thermal volume reduction processes tend to have high capital costs. There are immobilization processes and thermal volume reduction processes that can treat all classifications of spent ion exchange resin likely to be encountered. 40 refs., 19 figs., 17 tabs

    The aim of this study was to evaluate the effectiveness of PNF and manual therapy methods in the treatment of patients with cervical spine osteoarthritis, especially their efficacy in reducing pain and improving functionality in everyday life. Long-term results were also compared in order to determine which method of treatment is more effective. Eighty randomly selected females aged 45-65 were included in the study. They were randomly divided into two groups of 40 persons. One group received PNF treatment and the other received manual therapy (MAN.T). To evaluate functional capabilities, the Functional Rating Index was used. To evaluate changes in pain, a shortened version of the McGill Questionnaire was used. The PNF group achieved a greater reduction in pain than the MAN.T group. The PNF group showed a greater improvement in performing daily activities such as sleeping, personal care, travelling, work, recreation, lifting, walking and standing as well as decreased intensity and frequency of pain compared to the MAN.T group. The PNF method proved to be more effective in both short (after two weeks) and long (after three months) term.

  2. Role and Evaluation of Interlaboratory Comparison Results in Laboratory Accreditation

    Bode, P.

    2008-08-01

    Participation in interlaboratory comparisons provides laboratories an opportunity for independent assessment of their analytical performance, both in absolute way and in comparison with those by other techniques. However, such comparisons are hindered by differences in the way laboratories participate, e.g. at best measurement capability or under routine conditions. Neutron activation analysis laboratories, determining total mass fractions, often see themselves classified as `outliers' since the majority of other participants employ techniques with incomplete digestion methods. These considerations are discussed in relation to the way results from interlaboratory comparisons are evaluated by accreditation bodies following the requirements of Clause 5.9.1 of the ISO/IEC 17025:2005. The discussion and conclusions come largely forth from experiences in the author's own laboratory.

    Highlights: • Presented surface modification results in multimodal topography. • Laser treatment creates roughness in a range from nano- to micrometers. • Multimodal topography promote protein adsorption. • Hybrid surface treatment results in a texture favorable for osteogenic passes. - Abstract: Modern prosthesis often have a complex structure, where parts of an implant have different functional properties. This gradient of functional properties means that local surface modifications are required. Method presented in this study was develop to functionalize prefabricated elements with original roughness obtained by conventional treatments used to homogenize and clean surface of titanium implants. Demonstrated methodology results in multimodal, periodic grooved topography with roughness in a range from nano- to micrometers. The modified surfaces were characterized in terms of shape, roughness, wettability, surface energy and chemical composition. For this purpose, the following methods were used: scanning electron microscopy, optical profilometry, atomic force microscopy, contact angle measurements and X-ray photoelectron spectroscopy. Protein adsorption studies were conducted to determine the potential biomedical application of proposed method. In order to estimate the intensity and way of the protein adsorption process on different titanium surfaces, XPS studies and AFM measurements were performed. The systematic comparison of surface states and their osseointegration tendency will be useful to evaluate suitability of presented method as an single step treatment for local surface functionalization of currently produced implantable devices.

    Discriminant analysis was carried out for 48 tongue cancer patients who were treated with radium single-plane implantation. The 48 patients were grouped into 32 successfully cured without complications, five successfully cured with complications, six successfully cured but requiring additional boost therapy and five with local recurrence. To evaluate the relation between the dose distribution and the local treatment results, the analysis was based on a volume-dose relationship. The functions introduced by this discriminant analysis were linear, and the parameters used were modal dose, average dose and shape factors of histograms. Each group of treatment results had a correction rate of >80%, except for the successfully cured group with ulcers. The discriminant functions were useful as an index to obtain a final clinical treatment result at the early time of implantation, and these functions could be used as a criterion for the optimal treatment of tongue carcinoma. We were also able to recognize the limitation of the actual arrangement of sources in the single-plane implant. (author)

    The conservative management of perforated peptic ulcer has not gained widespread acceptance despite introduction of proton-pomp inhibitors because surgical procedures can achieve immediate closure by eventually using a laparoscopic approach. The aim of this prospective study was to evaluate the results of Taylor's method and to identify predictive factors of failure of medical treatment in patients presenting with perforated peptic ulcer. Between 1990 and 2000, 82 consecutive patients, with diagnosis of perforated peptic ulcer were prospectively included in this study. They were initially treated with non-operative procedure (nasogastric suction and intravenous administration of H2-blockers or proton-pomp inhibitors). No clinical improvement after 24 hours required a surgical treatment. Predictive factors of failure of non-operative treatment were tested in univariate or multivariate analysis. Clinical improvement was obtained with non-operative treatment in 54% of the patients (44/82). The overall mortality rate was 1%. In univariate analysis, significant predictive factors of failure of non-operative treatment were: size of pneumoperitoneum, heart beat >94 bpm, abdominal meteorism, pain at digital rectal exam, and age >59 years. In multivariate analysis, the significant factors were the size of pneumoperitoneum, heart beat, and abdominal meteorism. The association of these criteria: size of pneumoperitoneum >size of the first lumbar vertebra, heart beat >94 bpm, pain at digital rectal exam and age > 59 years , led to surgical treatment in all cases. These results suggest that more than 50% of patients with perforated peptic ulcer respond to conservative treatment without surgery and that the association of few criteria (size of pneumoperitoneum, heart beat, pain at digital rectal exam and age) require emergency surgery.

    In order to enhance the shelf-life of a late variety of Moroccan Citrus clementina (Nour), ionizing treatments were applied at 0.3 kGy, as well as washing (cold water) and waxing treatments. It has been found that, despite the irradiation treatment, the washing and waxing treatment do not improve the quality of C. clementina, but rather result in peel injury. Finally, sensory evaluation confirmed that irradiation had no detrimental effect on the quality of clementines

    The principle of evidence-based medicine is to integrate data concerning the efficacy of interventions into clinical practice. This article assesses the level of evaluation of psychosocial, psychopharmacological and combined interventions for mental disorders in childhood and adolescence (autistic disorders, hyperkinetic disorders, conduct disorders, tic disorders, enuresis, and encopresis). Three different levels of evaluation were defined for both psychosocial and psychopharmacological interventions: A (> or = 2 randomized controlled studies), B (1 randomized controlled study), and C (open studies and case studies). The level of evaluation was judged on the basis of original papers found in a comprehensive literature search. For most disorders presented in this article there are several A-level treatments. The efficacy of both psychosocial and psychopharmacological interventions that target specific problem behaviors or symptoms, respectively, has been repeatedly demonstrated with regard to autistic disorders. Many studies have evaluated treatment approaches for hyperkinetic disorders and conduct disorders. With regard to the treatment of tic disorders in children and adolescents, far more studies evaluated the efficacy of pharmacotherapy than of psychotherapy. Further research should compare the efficacy of different treatment approaches, examine specific and differential treatment effects and investigate combined treatment approaches.

Estrogen preparations provide the most effective treatment; local application is preferred to systemic drugs when treating only vaginal symptoms. As local estrogen therapies have comparable efficacy, this study aimed to understand treatment practices, assess experiences with different forms of local estrogen-delivering applicators, and evaluate satisfaction. Women who were US residents aged ≥18 years, menopausal (no spontaneous menstrual period for ≥1 year or with a double oophorectomy, and receiving local estrogen therapy for 1–6 months (vaginal cream [supplied with a reusable applicator] or vaginal tablets [supplied with a single-use/disposable applicator], completed an online questionnaire. Data from 200 women (100 cream users and 100 tablet users; mean therapy duration 3.48 months showed that most stored medication in the room in which it was applied (88% and applied it at bedtime (71%, a procedure for which cream users required, on average, more than twice the time of tablet users (5.08 minutes versus 2.48 minutes. Many cream users applied larger-than-prescribed amounts of cream, attempting to achieve greater efficacy (42%, or lower-than-recommended doses (45%, most frequently to avoid messiness (33% or leakage (30%.

    Full Text Available ABSTRACTOBJECTIVES: To evaluate the clinical and radiographic results and complications relating to patients undergoing arthroscopic treatment for femoroacetabular impingement by means of an extracapsular approach. METHODS: Between January 2011 and March 2012, 49 patients (50 hips underwent arthroscopic treatment for femoroacetabular impingement, performed by the hip surgery team of the Orthopedic Hospital of Passo Fundo, Rio Grande do Sul. Forty patients (41 hips fulfilled all the requirements for this study. The mean follow-up was 29.1 months. The patients were assessed clinically by means of the Harris Hip score, as modified by Byrd (MHHS, the Non-Arthritic Hip score (NAHS and the internal rotation of the hip. Their hips were also evaluated radiographically, with measurement of the CE angle, dimensions of the joint space, alpha angle, neck-head index, degree of arthrosis and presence of heterotopic ossification of the hip. RESULTS: Out of the 41 hips treated, 31 (75.6% presented good or excellent clinical results. There was a mean postoperative increase of 22.1 points for the MHHS, 21.5 for the NAHS and 16.4° for the internal rotation of the hip ( p< 0.001. Regarding the radiographic evaluation, correction to normal values was observed for the alpha angle and neck-head index, with a mean postoperative decrease of 32.9° and mean increase of 0.10, respectively ( p< 0.001. CONCLUSION: Arthroscopic treatment of femoroacetabular impingement by means of an extracapsular approach presented satisfactory clinical and radiographic results over a mean follow-up of 29.1 months, with few complications.

    To evaluate the results from surgical treatment of 84 cases of acute acromioclavicular dislocation, using a posterosuperior access route. Eighty-four cases of acute acromioclavicular dislocation (grade III in the Allman-Tossy classification) operated between November 2002 and May 2010 were evaluated. The patients' mean age was 34 years. The diagnoses were made using clinical and radiographic evaluations. The patients were operated by the same surgical team, within three weeks of the date of the trauma, using a posterosuperior approach to the shoulder to access the top of the base of the coracoid process for placement of two anchors, which were used in reducing the dislocation. The minimum follow-up was 12 months. The postoperative clinical-radiographic evaluation was done using the modified Karlsson criteria and the University of California at Los Angeles (UCLA) score. 92.8% of the 84 patients treated presented good or excellent results, and 7.2% presented fair or poor results, using the UCLA assessment score. According to the modified Karlsson criteria, 76.2% were assessed as grade A, 17.9% as grade B and 5.9% as grade C. The posterosuperior access route to the shoulder is a new option for accessing the coracoid process and treating acromioclavicular dislocation, with clinical and radiographic results equivalent to those in the literature.

    This paper reports on the design of a prototype in-vivo Stokes polarimetry probe for skin lesion evaluation, and preliminary results from skin phantom and clinical trials of this device. The probe releases a single millisecond-long pulse from a laser diode with either linear or circular polarization. It then captures the resulting backscattered far-field polarization speckle and calculates the Stokes parameters. This probe was designed with three novel innovations in mind. First, the Stokes vector is captured quickly, using low-cost components without the use of moving parts. Second, a compact collimated laser diode was used as the light source. Third, the device and detector geometry were designed to produce and capture a uniform speckle field. In the first clinical trial of this device, measurements were taken from a variety of skin lesions, both cancerous and benign. The Stokes vector was measured and used to calculate the degree of polarization (DOP), the azimuth angle, and the ellipticity angle of the polarization ellipse for two input light polarizations. Among other findings, the DOP for circular polarized input light was consistently lower than the DOP for linear polarized input light. These findings indicate the potential for a fast and low-cost in-vivo skin cancer screening tool, and encourages the continuing development of this probe's techniques.

    Full Text Available ABSTRACT OBJECTIVE: To evaluate the results of arthroscopic releases performed in patients with adhesive capsulitis refractory to conservative treatment. METHODS: This was a retrospective study, conducted between 1996 and 2012, which included 56 shoulders (52 patients that underwent surgery; 38 were female, and 28 had the dominant side affected. The mean age was 51 (29-73 years. The mean follow-up was 65 (12-168 months and the mean preoperative time was 8.9 (2-24 months. According to Zukermann's classification, 23 cases were considered primary and 33 secondary. With the patient in the lateral decubitus position, circumferential release of the joint capsule was performed: joint debridement; rotator interval opening; coracohumeral ligament release; anterior, posterior, inferior, and finally antero-inferior capsulotomy. A subscapularis tenotomy was performed when necessary. All patients underwent intense physical therapy in the immediate postoperative period. In 33 shoulders, an interscalene catheter was implanted for anesthetic infusion. Functional results were evaluated by the UCLA criteria. RESULTS: Improved range of motion was observed: mean increase of 45° of elevation, 41° of external rotation and eight vertebral levels of medial rotation. According to the UCLA score excellent results were obtained in 25 (45% patients; good, in 24 (45%; fair, in two (3%; and poor, in two (7%. Patients who had undergone inferior capsulotomy achieved better results. Only 8.8% of patients who used the anesthetic infusion catheter underwent postoperative manipulation. Seven patients had complications. CONCLUSION: There was improvement in pain and range of motion. Inferior capsulotomy leads to better results. The use of the interscalene infusion catheter reduces the number of re-approaches.

    Many patients treated on trauma surgery wards are geriatric trauma patients. To improve treatment of these often multimorbid patients, various interdisciplinary treatment concepts have been established in Germany between trauma surgeons and geriatricians. The aim of this study was to evaluate the dissemination and the impact of the different orthogeriatric treatment concepts for geriatric trauma in Germany. Material and methods In March and April 2014 an electronic questionnaire for assessing the interdisciplinary treatment of geriatric trauma patients was sent to 691 medical directors of trauma surgery departments in Germany. A total of 259 (37 %) fully answered questionnaires could be analyzed. The analysis revealed that 70 % of all responding trauma surgery departments had an orthogeriatric treatment cooperation. Most of them reported having patient discharge agreements to geriatric rehabilitation facilities (59 %). Geriatric counseling services were reported by 39 % while 24 % reported having regular interdisciplinary visits and orthogeriatric wards were available in 13 %. The need for orthogeriatric services was considered to be high by 79 % of the participants and benefits especially for the patients were expected. These expectations were largely fulfilled. More than 70 % of respondents planned to intensify the orthogeriatric cooperation. In this context difficulties were seen in the lack of personnel resources, especially in a lack of geriatricians. The results of this survey underline the impact and the positive experiences in orthogeriatric services. Solutions have to be found to address the emerging problem of capacity constraints.

  18. Complications of treatments of carcinoma on intact uterine cervix: results and prevention

    The prospective record of acute and late toxicity after treatment of cervix carcinomas is a part of the description of treatment outcome as well as local control and survival. Due to the large number of scales and glossaries used, the comparison of the results from one study to another is often difficult. The French-Italian syllabus seems to be the most reliable scale, providing implementation of quality of life assessment. The main predictive factor of complications, which is not related to the treatment type, is the previous history of abdominal or pelvic surgery. The incidence and severity of complications occurring after surgery are related to the surgical procedure and to the amount of peri-uterine tissues removed. The increase in dose and volume of external irradiation and brachytherapy and the increase in dose rate of the low-dose rate brachytherapy are responsible for the radiotherapeutic morbidity. The significant decrease of severe complication rates during the last 15 years was obtained by the implementation of individual adjustments in treatment planning. The treatment strategies of early bulky and advanced carcinomas are changing. Concurrent radiotherapy and chemotherapy is becoming a standard, but its late toxicity needs to be documented by a longer follow-up. The optimisation of radiation therapy should remain a reference to evaluate the outcome and morbidity of the new combined strategies: the addition of chemotherapy will never compensate for less than optimal radiotherapy/brachytherapy planning.

  19. Probabilistic seismic hazards: Guidelines and constraints in evaluating results

    International Nuclear Information System (INIS)

    Sadigh, R.K.; Power, M.S.

    1989-01-01

    In conducting probabilistic seismic hazard analyses, consideration of the dispersion as well as the upper bounds on ground motion is of great significance. In particular, the truncation of ground motion levels at some upper limit would have a major influence on the computed hazard at the low-to-very-low probability levels. Additionally, other deterministic guidelines and constraints should be considered in evaluating the probabilistic seismic hazard results. In contrast to probabilistic seismic hazard evaluations, mean plus one standard deviation ground motions are typically used for deterministic estimates of ground motions from maximum events that may affect a structure. To be consistent with standard deterministic maximum estimates of ground motions values should be the highest level considered for the site. These maximum values should be associated with the largest possible event occurring at the site. Furthermore, the relationships between the ground motion level and probability of exceedance should reflect a transition from purely probabilistic assessments of ground motion at high probability levels where there are multiple chances for events to a deterministic upper bound ground motion at very low probability levels where there is very limited opportunity for maximum events to occur. In Interplate Regions, where the seismic sources may be characterized by a high-to-very-high rate of activity, the deterministic bounds will be approached or exceeded by the computer probabilistic hazard values at annual probability of exceedance levels typically as high as 10 -2 to 10 -3 . Thus, at these or lower values probability levels, probabilistically computed hazard values could be readily interpreted in the light of the deterministic constraints

    Full Text Available Abstract Purpose The aim of this study was to evaluate treatment results in our hypopharyngeal cancer patients. Patients and Methods A total of three hundred and ninety five hypopharyngeal cancer patients received radical treatment at our hospital; 96% were male. The majority were habitual smokers (88%, alcohol drinkers (73% and/or betel quid chewers (51%. All patients received a CT scan or MRI for tumor staging before treatment. The stage distribution was stage I: 2 (0.5%; stage II: 22 (5.6%; stage III: 57 (14.4% and stage IV: 314 (79.5%. Radical surgery was used first in 81 patients (20.5%, and the remaining patients (79.5% received organ preservation-intended treatment (OPIT. In the OPIT group, 46 patients received radiotherapy alone, 156 patients received chemotherapy followed by radiotherapy (CT/RT and 112 patients received concomitant chemo-radiotherapy (CCRT. Results The five-year overall survival rates for stages I/II, III and IV were 49.5%, 47.4% and 18.6%, respectively. There was no significant difference in overall and disease-specific survival rates between patients who received radical surgery first and those who received OPIT. In the OPIT group, CCRT tended to preserve the larynx better (p = 0.088, with three-year larynx preservation rates of 44.8% for CCRT and 27.2% for CT/RT. Thirty-seven patients developed a second malignancy, with an annual incidence of 4.6%. Conclusions There was no survival difference between OPIT and radical surgery in hypopharyngeal cancer patients at our hospital. CCRT may offer better laryngeal preservation than RT alone or CT/RT. However, prospective studies are still needed to confirm this finding. Additionally, second primary cancers are another important issue for hypopharyngeal cancer management.

    Full Text Available Study Aim. Evaluation of results in blunt injury of the thoracic aorta (BAI endovascular treatment. Materials and Methods. Sixteen patients were treated for BAI. Thirteen patients had associated polytrauma, 4 of these had a serious hypotensive status and 4 had an hemothorax. In the remaining 3, two had a post-traumatic false aneurysm of the isthmus and 1 had a segmental dissection. In those 13 patients a periaortic hematoma was associated to hemothorax in 4. All patients were submitted to an endovascular treatment, in two cases the subclavian artery ostium was intentionally covered. Results. One patient died for disseminated intravascular coagulation. No paraplegia was recorded. No ischemic complications were observed. A type I endoleak was treated by an adjunctive cuff. During the followup (1–9 years 3 patients were lost. A good patency and no endoleaks were observed in all cases. One infolding and 1 migration of the endografts were corrected by an adjunctive cuff. Conclusion. The medium and long term results of the endovascular treatment of BAI are encouraging with a low incidence rate of mortality and complications. More suitable endo-suite and endografts could be a crucial point for the further improvement of these results.

    In order to evaluate the efficacy of, and the risk associated with, the definite treatment of euthyroid goiter with autonomy, the data of 88 patients treated between 1982 and 1986 (50 by subtotal thyroidectomy; 38 by 131 I-treatment, mean radiation dose 200 Gy without protection by thyroxine) were analyzed in a retrospective study. The following criteria were used before and after treatment: the results of scintigraphy under suppression qualitatively (in focal autonomy) and quantitatively (global thyroid uptake) (TcU s ), the means of FT 4 I, FT 3 I and ΔTSH after TRH, the improvement of mechanical signs and symptoms and the decrease of thyroid volume. Measured by TcU s and ΔTSH, autonomy could be removed completely in 85-90% of all patients. Surgery was slightly more successful (100%) compared to treatment by 131 I (75-80%). This was also true for removal of mechanical symptoms and reduction of the goiter. The incidence of manifest hypothyroidism was greater after surgery (16%) than after 131 I treatment (3%). At a higher grade of autonomy (TcU s > 3.2%) surgery was more effective (95-100%) than treatment with 131 I (60-70%) but at a higher risk of hypothyroidism (24 vs 0%). It is imperative to improve the methods of estimating the amount of 131 I to be administered in euthyroid goiter with autonomy. Selection of patients with autonomy in euthyroid goiter for definite treatment is difficult, since until now their risk to become hyperthyroid cannot be predicted properly. (orig.) [de

    Monopolar radiofrequency (RF) energy has been used to successfully accomplish noninvasive skin tightening of the face, abdomen, and extremities. Owing to concerns about injury to the eye itself, monopolar RF treatment of the eyelids has not been feasible. The objective was to evaluate the safety of a novel 0.25-cm(2)"shallow" treatment tip for noninvasive tightening of eyelid skin. This was a tripartite study that began with an animal model to evaluate soft tissue effects and temperature change at the ocular surface. Findings were then extrapolated to ex vivo evaluation of human eyelids and ultimately to an in vivo human eyelid safety study. The animal studies demonstrated that the 0.25-cm(2) treatment tip could be used safely on eyelids in conjunction with appropriate ocular protection. The ex vivo human eyelid studies confirmed that, at typical treatment settings, the shallow treatment tip did not produce frank eyelid injury. The in vivo human studies confirmed that, at the tested settings, the novel treatment tip did not injure the eyelids or eyes. If used properly, the 0.25-cm(2) treatment tip can be safely used on human eyelids.

    1998-09-01

    Full Text Available Acid sugarcane bagasse hydrolyzate was submitted to pH shifts in order to remove toxic compounds from the medium. The hydrolyzate was treated with bases containing mono-, di- or tri-valent cations and H2SO4, and its performance as a fermentation medium was evaluated by the production of xylitol by Candida guilliermondii FTI 20037. The use of bases containing mono-valent cations was not an efficient method of detoxification, and the use of a tri-valent cation did not show any detectable improvement in detoxification. The treated hydrolyzate recovery (in volume is greatly affected by the utilized base. Treatment using Al(OH3 and NaOH showed the best hydrolyzate recovery (87.5%, while the others presented a recovery of about 45% of the original hydrolyzate volume. Considering the whole process, best results were achieved by treatment using Al(OH3 and NaOH which allowed 0.55 g of xylitol produced from each gram of xylose in the raw hydrolyzate.

    Atypical antipsychotics have become the first-line treatment for patients suffering from schizophrenia in the industrialized world. Given the frequent necessity of a life-long enduring antipsychotic treatment, the compounds' safety profile is of great importance for patients and caregivers. Zotepine is an antipsychotic with atypical properties and previous data have suggested a very favorable side effect profile. The aim of this review is to provide a broad knowledge base on the safety profile of zotepine deriving from currently available research results published in English medical databases. The focus of this research reports starts in the 1990s with zotepine's approval in Europe. This paper incorporates data on placebo-controlled studies of zotepine as well as studies with comparator compounds also beyond the diagnostic boarder of schizophrenia regarding zotepine's safety. The take home message of this safety evaluation of zotepine is that compared to typical compounds zotepine induces less extrapyramidal side effects; however, in terms of comparing zotepine's safety with other atypical antipsychotics more studies are needed to draw final conclusions.

    Objectives Treatment interruptions (TI) of combination antiretroviral therapy (cART) are known to lead to unfavourable treatment outcomes but do still occur in resource-limited settings. We investigated the effects of TI associated with adverse events (AEs) and non-AE-related reasons, including their durations, on treatment failure after cART resumption in HIV-infected individuals in Asia. Methods Patients initiating cART between 2006-2013 were included. TI was defined as stopping cART for >1 day. Treatment failure was defined as confirmed virological, immunological or clinical failure. Time to treatment failure during cART was analysed using Cox regression, not including periods off treatment. Co-variables with p30 days were associated with failure (31-180 days HR=2.66, 95%CI (1.70-4.16); 181-365 days HR=6.22, 95%CI (3.26-11.86); and >365 days HR=9.10, 95% CI (4.27-19.38), all pfailure. If TI is unavoidable, its duration should be minimised to reduce the risk of failure after treatment resumption. PMID:26950901

    Residual stresses in materials arise due to the manufacturing processes. As a consequence, in the nuclear area some components must suffer a stress relief treatment according to strict criteria. Although these treatments are carefully carried on, concern with nuclear safety is constantly growing. This work proposes a nondestructive ultrasonic method to guarantee the efficiency of the heat treatment. It was used a short peened steel plate with tensile and compressive stresses which was submitted to a stress relief treatment. The results show that the proposed ultrasonic method could be used to confirm the efficiency of the stress relief heat treatment. (author)

    The aim of this study was to evaluate a physiotherapeutic treatment intervention in Bell's palsy. A consecutive series of nine patients with Bell's palsy participated in the study. The subjects were enrolled 4-21 weeks after the onset of facial paralysis. The study had a single subject experimental design with a baseline period of 2-6 weeks and a treatment period of 26-42 weeks. The patients were evaluated using a facial grading score, a paresis index and a written questionnaire created for this study. Every patient was taught to perform an exercise program twice daily, including movements of the muscles surrounding the mouth, nose, eyes and forehead. All the patients improved in terms of symmetry at rest, movement and function. In conclusion, patients with remaining symptoms of Bell's palsy appear to experience positive effects from a specific training program. A larger study, however, is needed to fully evaluate the treatment.

    Objective: To evaluate the interventional treatment of Budd-Chiari syndrome (BCS) with regard to different types of the disease. Methods: One hundred and fifty-nine consecutive cases with BCS underwent interventional treatments with regard to different types of the diseases, including percutaneous angioplasty (PTA), transcatheter thrombolysis, endovascular stent implantation and modified transjugular intrahepatic portosystemic shunt (MTIPS). Among them, 147 cases that underwent complete follow-up were enrolled in this study. Simple obstruction of HV, membranous obstruction of IVC, membranous obstruction of IVC combined with thrombosis in the distal lumen and segmental obstruction of IVC constituted 13.6% (20), 66.0% (97), 6.1% (9)and 14.3% (21/147), respectively. The technical success rate of each type was determined. They were followed up for (67.3±9.0) months (16 h-104 months). Overall primary patency rate was evaluated. The late effect on liver function was analyzed according to the Child-Pugh score. Results: The primary patency rate of PTA was 65.6% (86/131) and the secondary, patency rate was 96.9% (124/128). The primary patency rate of stent implantation was 78.9% (15/19) and the secondary patency rate was 92.3% (24/26). One patient of type IIIa that received recanalization, catheter-directed thrombolysis and PTA in IVC died of hemoptysis 72 h after the procedure. One patients of type I b who received MTIPS died of DIC 16 hrs after the procedure. And one patient of type Ib who received MTIPS died of liver failure 13 months after the procedure. Twelve patients died in 7-79 months after the interventional procedure due to unrelated causes. At the end of follow-up, the liver function of the patients was improved. Conclusions: Optimal application of various vascular interventional techniques has a satisfactory primary and secondary patency rate and improves the long-term liver function. (authors)

    Full Text Available Background. Fracture of the proximal 5th metatarsal bone (MTB reach almost 2% of all fractures of the foot. Conservative treatment is method of choice in almost all cases. Selected cases can benefit from acute surgery especially if the proximal fragment is severe displaced or the excessive articular step off is present.Materials and methods. In a 4 year period 14 patients were operated due to the acute fracture of proximal 5th MTB. All patients were treated in less than 2 weeks after the injury. 10 patients had base avulsion fracture in zone I and 4 had Jones fracture in zone II with dislocation of fragments? 5 mm, articular step off of 2 mm and 30% of articulation surface. We used tension bend wire in 9 cases (64%, partially threaded cancellous screw in 4 cases (28% and bone sutures in 1 case (7%. Postoperatively all patients used crutches with nonweight bearing for 4 weeks and afterwards partial weight bearing till the end of the treatment. All patients were practicing active exercises for ankle, foot and toes. The results were evaluated according to the Maryland Foot Score (MFS at least 20 months after injury.Results. 13 patients (93% were included in follow up. 12 patients were evaluated as excellent and only one as a good. All 13 patients have no or slight pain with no change in ADL or work ability. 9 patients (69% reached full functional result and 4 (31% patients had slight limitation during distance walk. Patients reached full weight bearing in average 7 weeks (5–13.Conclusions. Early operative treatment of selected cases allows fast return to preoperative activity without long term functional sequel. Both operative procedures, screw fixation and tension wire, yielded comparable and excellent end result.

    In 2 years and 5 months from April 1980 to May 1982, I had maked examination for computed tomography (CT) in head region by TCT-60A (TOSHIBA), and so reported the evaluation of following those results; 1) The number of CT scan was 1228 patients and total 1513 scannings. The contents of its scan were plain CT (86.1%), CE (contrast enhancement) CT (7.3%) and both application methods (6.6%), and included from 1 CT time (85.3%), 2 CT times (9.6%), 3 CT times (3.3%),... til 7 CT times. Our CT scan cases were 720 males (58.6%) and 508 females (41.4%);its scan age level was mostly 40 y.o. -- over 70 y.o., but low age patients (under 10 y.o.) indicated number of 15.3%. In consideration of this fact the advantage of CT scan was very easily and safely procedure free from body lesion. 2) In number of CT scan: the most many patients were visiting department of internal medicine clinic, and following pediatric clinic, surgery and orthopedic department. Above all CT scan cases were included of other all clinical departments in our hospital. (CT scan was very useful for neurological examination). 3) In CT diagnosis our cases were it of cerebral infarction 128 (10.4%), cerebral hemorrage 19 (1.5%) and brain tumor 24 (2.3%), in small cases other craniocerebral diseases. 4) The visiting cases in internal medicine often complain of cerebrovascular symptomes, and in pediatric clinic chief complain was often suspected mental retardation and neurological sign. In surgery department it was suspected metastatic brain tumor from other malignant cancers, and in orthopedic surgery often skull injury or traffic accident. (J.P.N.)

    A new inverse treatment planning system (TPS) for external beam radiation therapy with high energy photons is commercially available that utilizes both dose-volume-based cost functions and a selection of cost functions which are based on biological models. The purpose of this work is to evaluate quality of intensity-modulated radiation therapy (IMRT) plans resulting from the use of biological cost functions in comparison to plans designed using a traditional TPS employing dose-volume-based optimization. Treatment planning was performed independently at two institutions. For six cancer patients, including head and neck (one case from each institution), prostate, brain, liver, and rectal cases, segmental multileaf collimator IMRT plans were designed using biological cost functions and compared with clinically used dose-based plans for the same patients. Dose-volume histograms and dosimetric indices, such as minimum, maximum, and mean dose, were extracted and compared between the two types of treatment plans. Comparisons of the generalized equivalent uniform dose (EUD), a previously proposed plan quality index (fEUD), target conformity and heterogeneity indices, and the number of segments and monitor units were also performed. The most prominent feature of the biologically based plans was better sparing of organs at risk (OARs). When all plans from both institutions were combined, the biologically based plans resulted in smaller EUD values for 26 out of 33 OARs by an average of 5.6 Gy (range 0.24 to 15 Gy). Owing to more efficient beam segmentation and leaf sequencing tools implemented in the biologically based TPS compared to the dose-based TPS, an estimated treatment delivery time was shorter in most (five out of six) cases with some plans showing up to 50% reduction. The biologically based plans were generally characterized by a smaller conformity index, but greater heterogeneity index compared to the dose-based plans. Overall, compared to plans based on dose

    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

    Purpose: Age-related macular degeneration is the prevalent etiology of subfoveal choroidal neovascularization (CNV). The only effective treatment is laser photocoagulation, which is associated with decreased visual acuity following treatment in most patients. This study assessed both the response of subfoveal CNV to proton beam irradiation and treatment-related morbidity. We evaluated preliminary results in patients treated with an initial dose of 8 Cobalt Gray Equivalents (CGE) using a relative biological effectiveness (RBE) of 1.1. Methods and Materials: Twenty-one patients with subfoveal CNV received proton irradiation to the central macula with a single fraction of 8 CGE; 19 were eligible for evaluation. Treatment-related morbidity was based on Radiation Therapy Oncology Group (RTOG) criteria; response was evaluated by Macular Photocoagulation Study (MPS) guidelines. Fluorescein angiography was performed; visual acuity, contrast sensitivity, and reading speed were measured at study entry and at 3-month intervals after treatment. Follow-up ranged from 6 to 15 months. Results: No measurable treatment-related morbidity was seen during or after treatment. Of 19 patients evaluated at 6 months, fluorescein angiography demonstrated treatment response in 10 (53%); 14 (74%) patients had improved or stable visual acuity. With a mean follow-up of 11.6 months, 11 (58%) patients have demonstrated improved or stable visual acuity. Conclusion: A macular dose of 8 CGE yielded no measurable treatment morbidity in patients studied. Fluorescein nagiography demonstrated that regressed or stabilized lesions were associated with improved visual acuity as compared with MPS results. In the next phase, a dose of 14 CGE in a single fraction will be used to further define the optimal dose fractionation schedule

    To evaluate the long-term follow-up results of percutaneous ethanol injection (PEI) for the treatment of hepatocellular carcinoma (HCC) in Korea. Sixty-eight nodular HCCs initially detected in 64 patients, were subjected to US-guided PEI as a first-line treatment. Long-term survival rates, local tumor progression rates, and complications were evaluated, as were the influences of tumor size and Child-Pugh class on these variables. No major complications occurred. The overall survival rates of the 64 patients at three and five years were 71% and 39%, and their cancer-free survival rates were 22% and 15%, respectively. The overall survival rate of patients with a small HCC (≤ 2 cm) was significantly higher (p = 0.014) than that of patients with a medium-sized HCC (≤ 2 cm). The overall survival rate of patients with Child- Pugh class A was significantly higher (p = 0.049) than that of patients with Child- Pugh class B. Of 59 cases with no residual tumor, local tumor progression was observed in ablation zones in 18, and this was not found to be significantly influenced by tumor size or Child-Pugh class. The results of our investigation of the long-term survival rates of PEI in HCC patients in Korea (a hepatitis B virus-endemic area) were consistent with those reported previously in hepatitis C endemic areas. Patients with a smaller tumor or a better liver function exhibited superior survival rates

    To evaluate the results of the treatment of locally advanced but resectable rectal cancers and to analyze prognostic factors, especially with the emphasis on the treatment time factor. There were 71 patients with rectal cancer who had been treated by curative surgical procedure and postoperative radiotherapy from August 1989 to December 1993. The minimum follow up period was 24 months and the median follow-up was 35 months. Radiation therapy had been given by 6 MV linear accelerator by parallel opposing or four-box portals. Whole pelvis was treated up to 5040 cGy in most cases. Systemic chemotherapy had been given in 94% of the patients, mostly with 5-FU/ACNU regimen. Assessment for the overall and disease-free survival rates were done by life-table method and prognostic factors by Log-Rank tests. Five-year overall survival, disease-free survival were 58.8% and 57%, respectively. Two-year local control rate was 76.6%. Stage according to Modified Astler-Coller (MAC) system, over 4 positive lymph nodes, over 6 weeks interval between definitive surgery and adjuvant radiotherapy and over 7 days of interruption during radiotherapy period were statistically significant, or borderline significant prognostic factors. The treatment results of patients with rectal cancers are comparable to those of other large institutes. The treatment results for the patients with bowel wall penetration and/or positive regional lymph nodes were still discouraging for their high local recurrence rate for the patients with MAC 'C' stage diseases and high distant metastases rate even for the patients with node-negative diseases. Maybe more effective regimen of chemotherapy would be needed with proper route and schedule. To maximize postoperative adjuvant treatment, radiotherapy should be started at least within 6 weeks after surgery and preferably as soon as wound healing is completed. Interruption of treatment during radiotherapy course affects disease-free survival badly, especially if

    There is a continuing interest and need for resistance strain gages capable of making static strain measurements on components located in the hot section of gas turbine engines. A paper by Tsen-tai Wu describes the development and evaluation of high temperature gauges fabricated from specially developed Fe-Cr-Al-V-Ti-Y alloy wire. Several of these gages and a quantity of P12-2 ceramic adhesive were purchased for evaluation. Nine members of the aircraft turbine engine community were invited to participate in an evaluation of these gages. Each participant was sent one strain gage, a small amount of ceramic adhesive, instructions for mounting the gage on a test beam, and a set of suggestions for the experiment. Data on gage factor variation with temperature, apparent strain, and drift are discussed.

    Introduction: The purpose of this study was to evaluate the clinical efficacy in our daily practice, outside clinical trials, of cetuximab plus radiotherapy in a majority of treatment-naive patients with locoregionally advanced head and neck squamous cell carcinomas. Methods: A retrospective study was performed to evaluate outcomes in patients who were treated definitively with cetuximab and radiotherapy (ExRT). Patients with stage III or IV, nonmetastatic, measurable squamous cell carcinoma of the head and neck (SCCHN) were eligible. Results: There were 18 males and two females. The median age was 61 years (range from 49 to 87 years old). Concurrent radiotherapy and cetuximab was used, in first line, in 17 patients with locally advanced disease; two patients with recurrent SCCHN, who were intolerant of Cisplatin-based regimens, were treated with radiotherapy combined with weekly cetuximab; and 1 patient received cetuximab and radiotherapy postoperatively. The median time of response was 10 months (range from 2 to 24 months). A partial response was observed in 11 cases; a complete response in nine cases. The occurrence of grade 2–3 skin toxicity was observed in 11 cases. Skin toxicity was clearly correlated with a better response and the duration of the response to the treatment. The use of cetuximab in combination with radiotherapy does not increase the side effects of radiotherapy. At the end of the follow-up, 17 patients died. Conclusion: Cetuximab, with its highly targeted mechanism of action and synergistic activity with current treatment modalities, is a valuable treatment option in head and neck patients. The effect of the epidermal growth factor receptor antagonist occurs without any change in the pattern and the severity of toxicity usually associated with head and neck radiation. Cetuximab seems not to provide the most benefit for patients with oropharyngeal cancers but will in patients with T4 tumors. However, the median duration of local control was

    Full Text Available Introduction: Trigger Finger (tenosynovitis stenosans is a specific, named disease from a group of repetitive strain injury (RSI diseases, caused by inflammation which results in difficulties during muscle contraction and weakened and painful tendon movement. It is common in the outpatient physical medicine and rehabilitation practice. The aim of our study was to evaluate the success of conservative treatment of Trigger Finger by local instillation of corticosteroids.Methods: The study was designed as an observational and open analysis of the results of conservative treatment of 45 patients. We used precise instillation of steroid anti-inflammatory antirheumatic drugs in the area of patho-anatomic, microtraumatic injuries of tendon and its sheath. Patients were evaluated before and after the treatment with 0 to 5 evaluation score scale. The data were analyzed using X2 test.Results: Most of the patients had evaluation score of 2, 3 and 4, before the treatment. After the treatment 10 (29% patients had achieved score 4 and 35 (71% patients had achieved score 5. All of the patients with score 5 had excellent working ability with full working capacity. Other patients had well-preserved working ability, which improved to excellent in maximum of 7 days.Conclusions: Conservative treatment of Trigger finger shows good therapeutic effects and taking into account the benefits, convenience and generally lower cost of conservative treatment for the patient, should be considered as an effective alternative to surgical treatment.

    Aim of this work was to study how the detector resolution can affect the clinical significance of SBRT pre-treatment volumetric modulated arc therapy (VMAT) verification results. Three detectors (PTW OCTAVIUS 4D 729, 1500 and 100 SRS) used in five configurations with different resolution were compared: 729, 729 merged, 1500, 1500 merged and 1000 SRS. Absolute local gamma passing rates of 3D pre-treatment quality assurance (QA) were evaluated for 150 dose distributions in 30 plans. Five different kinds of error were introduced in order to establish the detection sensitivity of the three devices. Percentage dosimetric differences were evaluated between planned dosevolume histogram (DVH) and patients' predicted DVH calculated by PTW DVH 4D® software. The mean gamma passing rates and the standard deviations were 92.4% ± 3.7%, 94.6% ± 1.8%, 95.3% ± 4.2%, 97.4% ± 2.5% and 97.6% ± 1.4 respectively for 729, 729 merged, 1500, 1500 merged and 1000 SRS with 2% local dose/2mm criterion. The same trend was found on the sensitivity analysis: using a tight gamma analysis criterion (2%L/1mm) only the 1000 SRS detected every kind of error, while 729 and 1500 merged detected three and four kinds of error respectively. Regarding dose metrics extracted from DVH curves, D50% was within the tolerance level in more than 90% of cases only for the 1000 SRS. The detector resolution can significantly affect the clinical significance of SBRT pre-treatment verification results. The choice of a detector with resolution suitable to the investigated field size is of main importance to avoid getting false positive. Copyright © 2017 Associazione Italiana di Fisica Medica.

    A useful aid to the mathematical modeling of fermentation systems, for the kinetic evaluation of batch fermentations, is described. The generalized logistic equation may be used to describe the growth curves, substrate consumption, and product formation. A computer process was developed to fit the equation to experimental points, automatically determining the equation constants on the basis of the iteration algorithm of the method of non-linear least squares. By fitting the process to different master programs of various fermentations, the complex kinetic evaluation of fermentations becomes possible. Based on the analysis easily treatable generalized logistic equation, it is possible to calculate by computer different kinetic characteristics, e.g. rates, special rates, yields, etc. The possibility of committing subjective errors was reduced to a minimum. Employment of the method is demonstrated on some fermentation processes and problems arising in the course of application are discussed.

    This study was undertaken to compare the biological efficacy of different high-dose-rate (HDR) and low-dose-rate (LDR) treatments of gynaecological lesions, to identify the causes of possible nonuniformity and to optimise treatment through customised calculation. The study considered 110 patients treated between 2001 and 2006 with external beam radiation therapy and/or brachytherapy with either LDR (afterloader Selectron, (137)Cs) or HDR (afterloader microSelectron Classic, (192)Ir). The treatments were compared in terms of biologically effective dose (BED) to the tumour and to the rectum (linear-quadratic model) by using statistical tests for comparisons between independent samples. The difference between the two treatments was statistically significant in one case only. However, within each technique, we identified considerable nonuniformity in therapeutic efficacy due to differences in fractionation schemes and overall treatment time. To solve this problem, we created a Microsoft Excel spreadsheet allowing calculation of the optimal treatment for each patient: best efficacy (BED(tumour)) without exceeding toxicity threshold (BED(rectum)). The efficacy of a treatment may vary as a result of several factors. Customised radiobiological evaluation is a useful adjunct to clinical evaluation in planning equivalent treatments that satisfy all dosimetric constraints.

    Eleven epileptic men who complained of epilepsy and sexual dysfunction were submitted to a multidisciplinary evaluation. Mean age was 27 years (20-34), mean epilepsy duration was 19 years (0.5-32) and the mean seizure frequency was two by week (0-7). Ten patients had partial seizures and one other had myoclonic epilepsy. Ten patients were treated with antiepileptic drugs (phenytoin--1, carbamazepine--8, clonazepam--3, clobazam--2, valproic acid--3, vigabatrin--1). As defined in the DSM III-R, the complaints were: erectile disorder (9), hypoactive sexual desire disorder (4), frotteurism (4), inhibited orgasm (3), premature ejaculation (3), fetishism (2), voyeurism (2), exhibitionism (2), pedophilia (1) and sexual aversion disorder (1). Two patients showed hypogonadotropic hypogonadism on endocrinologic screening. Urological evaluation disclosed organic erectile dysfunction in other two. One patient had a diagnosis of psychogenic sexual disorder. In six patients a conclusive etiologic diagnosis was not reached. This report shows the multifactorial nature of sexual disorder in epilepsy and underlies the need of a multidisciplinar evaluation.

    Fibromyalgia is associated with substantial functional disability. Current drug and non-drug treatments result in statistically significant but numerically small improvements in typical numeric measures of pain severity and fibromyalgia impact. The aim of the present study was to evaluate additional measures of pain severity and functional outcome that might be affected by fibromyalgia treatment. This retrospective review evaluated outcomes from 274 adults with fibromyalgia who participated in a six-week, multidisciplinary treatment programme. Pain and function were evaluated on the first and final treatment visit. Pain was evaluated using an 11-point numerical scale to determine clinically meaningful pain reduction (decrease ≥ 2 points) and from a pain drawing. Function was evaluated by measuring active range of motion (ROM), walking distance and speed, upper extremity exercise repetitions, and self-reports of daily activities. Numerical rating scores for pain decreased by 10-13% (p Fibromyalgia Impact Questionnaire (FIQ) scores decreased by 20% (p fibromyalgia treatment effectiveness. © 2013 John Wiley & Sons, Ltd.

    Full Text Available In recent years detection of various adrenal tumors has increased greatly. Total adrenalectomy remains the standart of surgical managment for adrenal tumors, although, the vast majority of these tumors turn out to be benign on the routine histological examination. Performing organ-sparing surgery would allow to avoid hormone insufficiency after total adrenalectomy. Aim: to compare results of adrenal tumors treatment by different volume of surgical interventions. Materials and methods. We evaluated the short-term results of 237 patients treatment with various adrenal tumors. Total adrenalectomy were performed on 206 cases, 31 patients undergone adrenal resection. There were analyzed intraoperative and postoperative complications, assessed the hormonal status of the patients, depending on the extent of surgical treatment. Besides, the long-term results were evaluated in 141 patients underwent total adrenalectomy and 30 patients after organ-sparing surgery. Moreover, we analyzed the percentage of recurrenses, assessed the hormonal status of the patients and the effectiveness of treatment. Results. Performing the organ-sparing operations doesn't increase the risk of intraoperative complications. In all patients with hormone-active tumors we found decline of pathologically increased hormone levels and trend to regress of clinical manifestations of the disease in early postoperative period. We found no difference in local recurrences in both groups, and its occurrence did not exceed 3.33%. Refractory postoperative adrenal insufficiency was observed only in corticosteroma patients in spite of surgery volume. In case of both side adrenal tumors there was no need in replacement therapy after total adrenalectomy from there one side and resection from the other. Conclusions. In cases of adrenal tumor performing organ-sparing operations is advisable, if there are no preoperative sings of malignancy.

    Patients and Methods: This longitudinal study prospectively evaluates quality of life in two groups consisting of 53 neoadjuvant and primarily surgically treated patients with oral cancer, using the quality-of-life core questionnaire (QLQ-C30) and the head and neck cancer module (H and N 35) of the European Organization for Research and Treatment of Cancer (EORTC). Results: Postoperatively both groups showed a marked reduction in quality of life. 1 year later quality of life had equalized between the two groups to such an extent that the quality of life scores had almost reached the preoperative level. Both groups showed specific impairments in the symptom scales. In the neoadjuvant therapy group however, global health and the emotional status were reduced to a greater degree than in the other group. Conclusion: Temporary limitations in quality of life can be expected after tumor treatment of oral cancer as presented here. Neoadjuvant therapy concept is more aggressive and might result in a longer disease-free survival, but the restriction in quality of life is more severe. Primary goal is the eradication of the tumor. Nevertheless preservation or reconstruction of a maximum of function is essential for a high level of quality of life. (orig.)

    Objective: Objective To evaluate the clinical characteristics and treatment results of 60 patients with large cell lung cancer (LCLC). Methods: All sixty-two patients were diagnosed histopathologically with 5 in stage I, 13 in stage II, 30 in stage III and 14 in stage IV. Forty-five patients received primary surgical resection with 38 radical resection and 7 palliative resection. Non-surgical treatment was given to 17 patients. Mediastinum and ipsilateral hilum were treated to the total dose of 40-60 Gy in 4-6 weeks in 16 patients as postoperative adjuvant radiotherapy. For patients treated by radiation alone, the primary tumor bed, bilateral mediastinum and ipsilateral hilum were treated to the total dose of 36-70 Gy in 4-7 weeks. Results: The overall 1-, 3- and 5- year survival rates were 25.7%, 15.4% and 11.6%, respectively with the median survival time of 11.6 months. In the radically resected patients, the 1-, 3- and 5-year survival rates and the median survival time were 51.3%, 24.7%, 24.7% and 13 months, compared to those of 0%, 0%, 0% and 2 months in the palliatively resected group. In non-surgical treatment group, the 1-, 3- and 5-year survival rates and the median survival time were 41.2%, 21.2%, 7.0% and 11 months, respectively. Conclusions: The prognosis of large cell lung cancer is poor due to high distant metastasis rate. The long-term survival rate after radical resection is worse than the other lung cancers, but similar to the non-surgical treatment. (authors)

    Histotripsy was evaluated as a non-invasive BPH treatment. The prostates of 21 canine subjects were targeted with one of three histotripsy doses. Prostates were harvested immediately, 7 days, or 28 days after treatment and assessed for changes. Lower treatment doses were found to produced scattered cellular disruption and hemorrhage that was sometimes reversible. Higher doses perforated the urethra and produced cavities in the glandular prostate that healed to leave an enlarged urinary channel.

    Key for successful jugulotympanic paraganglioma management is a personalised approach aiming for the best practice for each individual patient. To this end, a systematic review is performed, evaluating the local control and complication rates for the different treatment modalities stratified by the broadly accepted Fisch classification. A systematic literature review according to the PRISMA statement was performed. A detailed overview of individual treatment outcomes per Fisch class is provided. Local control, cranial nerve damage, complications, function recovery. Eighteen studies were selected, resembling 83 patients treated with radiotherapy and 299 with surgery. Excellent local control was found post-surgery for class A and B tumours, and risk of cranial nerve damage was class C1-4 tumours, local control was 80%-95% post-surgery (84% post-radiotherapy), and cranial nerve damage was found in 71%-76% (none post-radiotherapy; P class. For class C1-4De/Di tumours, local control was 38%-86% (98% post-radiotherapy; P class. For class A and B tumours, surgery is a suitable treatment option. For class C and D tumours, radiotherapy results in lower complication rates and similar or better local control rates when compared to the surgical group. © 2017 John Wiley & Sons Ltd.

    Purpose: To evaluate the safety and therapeutic efficacy of ultrasound (US)-guided high-intensity focused ultrasound (HIFU) ablation for the treatment of abdominal wall endometriosis (AWE). Materials and methods: Twenty-one consecutive patients with AWE were treated as outpatients by US-guided HIFU ablation under conscious sedation. The median size of the AWE was 2.4 cm (range 1.0-5.3 cm). An acoustic power of 200-420 W was used, intermittent HIFU exposure of 1 s was applied. Treatment was considered complete when the entire nodule and its nearby 1 cm margin become hyperechoic on US. Pain relief after HIFU ablation was observed and the treated nodule received serial US examinations during follow-up. Results: All AWE was successfully ablated after one session of HIFU ablation, the ablation time lasted for 5-48 min (median 13 min), no major complications occurred. The cyclic pain disappeared in all patients during a mean follow-up of 18.7 months (range 3-31 months). The treated nodules gradually shank over time, 16 nodules became unnoticeable on US during follow-up. Conclusion: US-guided HIFU ablation appears to be safe and effective for the treatment of AWE.

    Full Text Available Aim: To evaluate the local control of hepatic metastasis with radiofrequency ablation treatment. Materials and Methods: We did a retrospective analysis in 40 patients treated with radiofrequency ablation for hepatic metastasis. The tumors ablated included up to two metastatic liver lesions, with primaries in breast, gastrointestinal tract, cervix, etc. Radiofrequency ablation was performed under general anesthesia in all cases, using ultrasound guidance. Radionics Cool-Tip RF System was used to deliver the treatment. Results: The median age of patients treated was 49 years. There were 13 female and 27 male patients. The median tumor size ablated was 1.5 cm (0.75-4.0 cm. A total of 52 radiofrequency ablation cycles were delivered. Successful ablation was achieved in all patients with hepatic metastasis less than 3 cm in size. Pain was the most common complication seen (75%. One patients developed skin burns. At 2-year follow-up 7.5% of patients had locally recurrent disease. Conclusions: Radiofrequency ablation is a minimally invasive treatment modality. It can be useful in a select group of patients with solitary liver metastasis of less than 3 cm size.

    2004-01-01

    A forecast of the radioactive, dangerous liquid effluents expected to be produced by the Waste Treatment Plant (WTP) was provided by Bechtel National, Inc. (BNI 2004). The forecast represents the liquid effluents generated from the processing of Tank Farm waste through the end-of-mission for the WTP. The WTP forecast is provided in the Appendices. The WTP liquid effluents will be stored, treated, and disposed of in the Liquid Effluent Retention Facility (LERF) and the Effluent Treatment Facility (ETF). Both facilities are located in the 200 East Area and are operated by Fluor Hanford, Inc. (FH) for the US. Department of Energy (DOE). The treatability of the WTP liquid effluents in the LERF/ETF was evaluated. The evaluation was conducted by comparing the forecast to the LERF/ETF treatability envelope (Aromi 1997), which provides information on the items which determine if a liquid effluent is acceptable for receipt and treatment at the LERF/ETF. The format of the evaluation corresponds directly to the outline of the treatability envelope document. Except where noted, the maximum annual average concentrations over the range of the 27 year forecast was evaluated against the treatability envelope. This is an acceptable approach because the volume capacity in the LERF Basin will equalize the minimum and maximum peaks. Background information on the LERF/ETF design basis is provided in the treatability envelope document

  12. Evaluation of allowed outage time using PRA results

    International Nuclear Information System (INIS)

    Johanson, G.

    1985-01-01

    In a probabilistic risk assessment (PRA) different measures of risk importance can be established. These measures can be used as a basis for further evaluation and determination of allowed outage time for specific components, within safety systems of a nuclear power plant. In order to optimize the allowed outage time (AOT) stipulated in the plant's Technical Specification it is necessary to create a methodology which could incorporate existing PRA data into a quantitative extrapolation. In order to evaluate the plant risk status due to AOT in a quantitative manner, the risk achievement worth is utilized. Risk achievement worth is defined as follows: to measure the worth of a feature, in achieving the present risk, one approach is to remove the feature and then determine how much the risk has increased. Thus, the risk achievement worth is formally defined to be the increase in risk if the feature were assumed not be there or to be failed. Another parameter of interest for this analysis is the shutdown risk increase. The shutdown risk achievement worth must be incorporated into the accident sequence risk achievement worth to arrive at an optimal set of plant specific AOTs

    As water is becoming a rare resource, the onsite reuse and recycling of grey water is practiced in many countries as a sustainable solution to reduce the overall urban water demand. However, the lack of appropriate water quality standards or guidelines has hampered the appropriate grey water reuses. Based on literature review, a non-potable urban grey water treatment and reuse scheme is proposed and the treatment alternatives for grey water reuse are evaluated according to the grey water characteristics, the proposed standards and economical feasibility.

    We evaluated the failure pattern of the celiac axis, gastric lymph node, and treatment outcome in the upper and mid-esophageal region of cancer patients treated by definitive radiotherapy, except when treating the celiac axis and gastric lymph node for treatment volume, retrospectively. Materials and Methods: The study constituted the evaluation 108 patients with locally advanced esophageal cancer receiving radiotherapy or a combination of radiotherapy and chemotherapy at Chonbuk National University Hospital from January 1986 to December 2006. In total, 82 patients treated by planned radiotherapy, except when treating the celiac axis and gastric lymph node for treatment volume, were analysed retrospectively. The study population consisted of 78 men and 2 women (mean age of 63.2 years). In addition, 51 patients received radiotherapy alone, whereas 31 patients received a combination of radiation therapy and chemotherapy. The primary cancer sites were located in the upper portion (17 patients), and mid portion (65 patients), respectively. Further, the patients were in various clinical stages including T1N0-1M0 (7 patients), T2N0-1M0 (18 patients), T3N0-1M0 (44 patients) and T4N0-1M0 (13 patients). The mean follow up period was 15 months. Results: The various treatment outcomes included complete response (48 patients), partial response (31 patients) and no response (3 patients). The failure patterns of the lymph node were comprised of the regional lymph node (23 patients) and the distance lymph node which included celiac axis and gastric lymph node (13 patients). However, metastasis was not observed in the regional and distant lymph node in 10 patients, whereas 36 patients were not evaluated. Furthermore, of the 13 patients who developed celiac axis and gastric lymph node metastases, 3 were in stage T1N0-1M0 and 10 were in stage T2-4N0-1M0. A complete response appeared in 12 patients, whereas a partial response appeared in 1 patient. The mean survival time of the

    Full Text Available Background: Velopharyngeal insufficiency causes hypernasal vocal quality and can also result in audible nasal air emission and difficulty in producing pressure consonants. The resulting speech is often socially unacceptable and can be difficult to understand. Platelet-rich plasma is an autologous derivative of whole blood. Today, the importance of clinical use of Platelet-rich plasma in the plastic surgery is considered. This study was designed to evaluate the effectiveness of combined Platelet-rich plasma and fat injection in the treatment of velopharyngeal insufficiency. Methods: In this prospective clinicaltrial study, of 15 patients including 9 males and 6 females and aged 15-20 years with mild/ moderate velopharyngeal insufficiency who were injected with 5 mL of combined Platelet-rich plasma (1 mL and fat (4 mL in the front volume in the posterior pharyngeal wall in the pre-vertebral fascia under sedation. Speech samples were recorded by nasoendoscopy before the injection, and at 6 weeks and 6 months after the injection. Assessment of pathologic speech was done by speech therapist. Results: Velar displacement showed significantly increased at 6 weeks after the injection (P=0.049. Velopharyngeal gap disappeared in 60% of patients at 6 weeks after the injection (P=0.019. Lateral pharyngeal wall movement showed significantly increased in 73.3% of the patients at 6 months after the injection (P=0.04. After the treatment, aerodynamic assessment showed significantly decreased in nasal air escape during phonation and repeat the words (P<0.05. Assessment speech therapist showed significantly improve quality of phonation in these patients (P<0.05. Conclusion: It seems that, combined Platelet-rich plasma and fat injection lead to improve voice resonance and reduce nasal air escape in all treated cases. It can be a promising alternative to major procedures, such as velopharyngoplasties, for the treatment of mild/ moderate velopharyngeal insufficiency.

    strength. As soon as the applied load is lower than the aggregate strength, the mode of stress transmission is discrete as stresses were mainly transmitted through chain of aggregates. With increasing applied load soil aggregates start deforming that transformed heterogeneous soil into homogenous......, as a result stress transmission mode was shifted from discrete towards more like a continuum. Continuum-like stress transmission mode was better simulated with Boussinesq (1885) model based on theory of elasticity compared to discrete. The soil-pore structure was greatly affected by increasing applied...... and compaction-resulted soil structure at the same time. Stress transmission was quantified using both X-ray CT and Tactilus sensor mat, and soil-pore structure was quantified using X-ray CT. Our results imply that stress transmission through soil highly depends on the magnitude of applied load and aggregate...

    To determine the epidemiological profile of women admitted for urinary tract infection as well as to verify the most prevalent agents and response to antibiotic therapy. A retrospective study of 106 pregnant women admitted to a university hospital for urinary tract infection treatment during the period between January 2007 to December 2010. The evaluation was based on analysis of the medical records of these pregnant women, with the observation of hospitalization and pregnancy data, as well as its outcome. Statistical analysis was performed using Statistical Package for the Social Science, version 15.0. The bilateral Fisher exact test and Student's t test were used for data analysis, as well as descriptive statistical methods. Positive urine cultures were observed in 60.5% of pregnant women admitted due to urinary tract infection. The most frequent infectious agent was Escherichia coli and no difference in resistance, recurrence or complications was observed between the most frequent etiologic agents. Pregnant women with previous UTI had a higher recurrence risk (OR=10.8; p<0.05). The antibiotics most commonly used during hospitalization were ampicillin and cefazolin. Change of therapeutic agent due to bacterial resistance occurred in 11.9% of patients who took cefazolin and in 20% of patients who took ampicillin (OR=5.5; p<0.05). The rate of gestational complications was the same for both treatments. There was no difference in mean number of days of hospitalization between the treatments. In the studied population ampicillin showed a higher rate of bacterial resistance than cefazolin, requiring a larger number of treatment regimen exchanges, without resulting in differences in clinical outcome or time of hospitalization.

    Internal carotid artery bifurcation aneurysms (ICAbifAs) present unique challenges to endovascular and surgical operators, and little is known about their natural history. We reviewed our institution's experience with ICAbifAs studying outcomes of surgical and endovascular management and natural history. Consecutive patients with unruptured ICAbifAs evaluated and/or treated over an 8-year interval were studied. Baseline demographics, neurovascular risk factors, aneurysm location and size, clinical presentation, treatment recommendations, and outcomes were prospectively collected and retrospectively analyzed. Continuous variables were compared with Student's t test and categorical variables with Chi-square tests. Fifty-nine patients with 61 unruptured ICAbifAs were included. Seven aneurysms were treated surgically (11.5 %), 22 underwent endovascular treatment (36 %), and 32 were managed conservatively (52.5 %). In the surgical group, short- and long-term complete aneurysm occlusion rates were 100 % with no cases of perioperative or long-term permanent morbidity or treatment-related mortality. In the endovascular group, two patients (11.7 %) with giant aneurysms had perioperative thromboembolic events with transient morbidity. There was one case of aneurysm rupture at follow-up in a giant aneurysm treated with partial coil embolization. Complete/near-complete occlusion rates were 63 %. There was one case of aneurysm rupture after 114 aneurysm-years of follow-up in the conservative management group (0.89 %/year), but no ruptures were observed in small aneurysms selected for conservative management. Unruptured small ICAbifAs have a benign natural history. In patients selected for treatment, excellent results can be achieved in the vast majority of patients with judicious use of endovascular and surgical therapy.

    The purpose of this study was to evaluate the mid- and long-term results of percutaneous transhepatic cholangiography (PTC) and biliary drainage in children with isolated bilioenteric anastomotic stenosis (BAS) after pediatric liver transplantation. Sixty-four children underwent PTC from March 1993 to May 2008. Nineteen cholangiograms were normal; 10 showed intrahepatic biliary stenosis and BAS, and 35 showed isolated BAS. Cadaveric grafts were used in 19 and living donor grafts in 16 patients. Four patients received a whole liver, and 31 patients received a left lobe or left lateral segment. Roux-en-Y hepaticojejunostomy was performed in all patients. Indication for PTC was based on clinical, laboratory, and histopathologic findings. In patients with isolated BAS, dilation and biliary catheter placement, with changes every 2 months, were performed. Patients were separated into 4 groups according to number of treatment sessions required. The drainage catheter was removed if cholangiogram showed no significant residual stenosis and normal biliary emptying time after a minimum of 6 months. The relationship between risk factors (recipient's weight 20 months, 4 patients (4 of 35; 11.4%) required 1 additional treatment session (group III), and 1 patient (1 of 35; 2.9%) had a catheter placed at the end of the study period (group IV). Drainage time in group I was significantly shorter than those in groups II, III, and IV (p 0.05). The majority of complications, such as catheter displacement and leakage, were classified as minor; however, 2 patients (5.7%) with hemobilia were noted. Complications increased according to the need for reintervention. In conclusion, balloon dilation and percutaneous drainage placement is safe and effective, and it has long-term patency for children with BAS after liver transplantation. Because of prolonged treatment time, reintervention may be necessary, thereby increasing the complication rate. Balloon dilation and percutaneous drainage

    The results of operative treatment for recalcitrant midportion Achilles tendinopathy and recalcitrant retrocalcaneal bursitis were evaluated using the patient administered, disease specific, and validated VISA-A-G questionnaire. A cohort of 89 patients was prospectively followed. These patients underwent operations for sport induced midportion Achilles tendinopathy (39 procedures) or retrocalcaneal bursitis (55 procedures). Depending on the individual intraoperative findings the patients of either disease were treated with two respective operative modifications (tendon repair or no tendon repair). Preoperative and follow-up status (3, 6, and 12 months) were investigated using the VISA-A-G questionnaire. Preoperatively, the four groups scored from 37.0 ± 17.6 to 45.9 ± 15.2 (p = 0.376-0.993) on the VISA-A-G questionnaire. Six and 12 months postoperatively, the VISA-A-G scores improved significantly (p bursitis and midportion Achilles tendinopathy responded equally well to operative treatment. When repaired, additional tendon lesions did not influence this result. We demand to differentiate not only between midportion Achilles tendinopathy and retrocalcaneal bursitis but also to identify additional Achilles tendon lesions to specifically address these lesions during operative procedures.

    To assess and grade facial nerve dysfunction according to the extent of facial paralysis in the clinical course of acupuncture treatment for Bell's palsy, and to observe the interrelationship between the grade, the efficacy and the period of treatment, as well as the effect on prognosis. The authors employed the House-Brackmann scale, a commonly used evaluation scale for facial paralysis motor function, and set standards for eye fissure and lips. According to the improved scale, the authors assessed and graded the degree of facial paralysis in terms of facial nerve dysfunction both before and after treatment. The grade was divided into five levels: mild, moderate, moderately severe, severe dysfunction and complete paralysis. The authors gave acupuncture treatment according to the state of the disease without artificially setting the treatment period. The observation was focused on the efficacy and the efficacy was evaluated throughout the entire treatment process. Fifty-three cases out of 68 patients with Bell's palsy were cured and the overall rate of efficacy was 97%. Statistically significant differences (PBell's palsy in terms of severity of facial nerve dysfunction. Efficacy is reduced in correlation with an increase in facial nerve dysfunction, and the period of treatment varies in need of different levels of facial nerve dysfunction. It is highly necessary to assess and grade patients before observation and treatment in clinical study, and choose corresponding treatment according to severity of damage of the disease.

    Full Text Available Objective: Falls are one of the major problems in the elderly and are considered one of the “Geriatric Giants”. Recurrent falls an important cause of morbidity and mortality in this segment of the population and is a marker of poor physical and cognitive status. The aim of the present study is to compare the VNG (Videonystagmography test results in adults with and without falls history. Materials & Methods: 60 adults ( 30 with one or more falls history and 30 without any falls history above 65 year old performed the VNG subtests included saccade, gaze, smooth pursuit, positional nystagmus, spontaneous nystagmus and caloric at rehabilitation faculty of Tehran University of Medical Sciences. Results: According to the data 74% of the faller group showed abnormal performance in the caloric subtest and more than 60% had abnormal results in the saccade, gaze and smooth pursuit subtests too. The members who suffered from central vestibular disorders had worse function than the others who suffered from peripheral vestibular ones. Conclusion: The non- faller group had better performance than the faller group in all of the subtests which indicates better vestibular system status in this group. According to the results, VNG performance can help guide the clinicians in the development of a safe exercise program.

    Treatment results for uterine cervix cancer were evaluated using a new concept named ''Effective Survival Rate''. This rate was calculated by subtracting the weighted sum of incidence rates of various complications from the 5-year survival rate. The numerical values for various complications were assigned as follows: surgical death, 1.0; severe complications, such as fistula ureterovaginalis and ileus, 0.5; mild complications, such as rectum and urinary bladder complications, 0.3 and 0.2. These values were determined with reference to the Karnofsky index of performance status. The effective survival rate was calculated for patients with satage 2 and 3 uterine cervix cancer treated by radiation therapy and surgery, and compared as a function of age between 30 and 70 years. We concluded that the effective survival rate was comparable for radiation therapy and surgery for stage 2 uterine cervix cancer. However, in patients with stage 3, radiation therapy was superior.

    Esophageal motor and sensory disorders are relatively rare conditions in the general population and afflicted patients are often initially misdiagnosed as having gastroesophageal reflux disease. Tests for these disorders have imperfect gold standards and are adjuncts to sound diagnostic reasoning. Treatments are palliative and have not been rigorously evaluated for some disorders. Symptoms and complications from disease progression and relapse are common, so that patients need continued follow-up.

    Full Text Available BACKGROUND AND AIM:Estimation of need and demand for orthodontic treatment is important for both healthprofessionals and health policymakers. Need assessment is traditionally done using experts’ opinions;however, patient-centered evaluation can provide a bigger picture ofpatient’s esthetic and psychological needs. The willingness to pay(WTP technique is a potentially valid tool for assessing the patient views on their needs and for market research inhealthcare.The aim of this study was to evaluate the need anddemand for orthodontic treatment with a patient-centeredapproach using economic analysis.METHODS:A cross-sectional study was designed. Two hundred people attending Shiraz Dental School Clinic wereinterviewed. Their views on the importance and costs of orthodontic treatments and the maximum amountthat theywould pay for such treatments were obtained along with their demographic and socioeconomic factors. Their WTP wasused to elicit values for orthodontic treatment using contingent valuation method (CVM and econometric techniques.RESULTS:The response rate was 95%. Although 53.5% of respondents felt they needed orthodontic treatment, only33.7% had expressed their need, and just 17.5% hadactually gone for such treatment. The main reason for not takingthe treatment was its cost (56.5%. More than 60% of respondents viewed orthodontics as only a luxurytreatment and70% considered beauty and elegant smile as the most, or one of the most, benefit(s of orthodontic treatments. WTPresults showed that orthodontic services have highdemand elasticity. Assuming fixed monthly income of8 millionRials, 61% of subjects were ready to pay 20 millionRials for a course of orthodontic treatment.CONCLUSIONS:The result showed that esthetics and high cost of treatment were respectively the most intriguing andthemain inhibiting factors for getting orthodontic treatment. Economic evaluation showed a high elastic estimation fororthodontic treatment.

    Root resorption is commonly seen, albeit in varying degrees, in cases that have been treated orthodontically. In this retrospective study the objective was to compare the amount of root resorption observed after active orthodontic treatment had been completed with one of three different appliance systems, namely, Tip Edge, Modified Edgewise and Damon. The sample consisted of pre and post-treatment cephalograms of sixty eight orthodontic cases. Root resorption of the maxillary central incisor was assessed from pre- and post- treatment lateral ce phalograms using two methods. In the first, overall tooth length from the incisal edge to the apex was measured on both pre and post-treatment lateral cephalograms and root resorption was recorded as an actual millimetre loss of tooth length. There was a significant upward linear trend (p = 0.052) for root resorption from the Tip Edge Group to the Damon Group. In the second method root resorption was visually evaluated by using the five grade ordinal scale of Levander and Malmgren (1988). It was found that the majorty of cases in the sample came under Grade 1 and Grade 2 category of root resorption. Statistical evaluation tested the extent of agree ment in this study between visual measurements and actual measurements and demonstrated a significant association (p = 0.018) between the methods.

    Accurate estimation of stress transmission and resultant deformation in soil profiles is a prerequisite for the development of predictive models and decision support tools for preventing soil compaction. Numerous studies have been carried out on the effects of soil compaction, whilst relatively few studies have focused on the cause (mode of stress transmission in the soil). We have coupled both cause and effects together in the present study by carrying out partially confined compression tests on (1) wet aggregates, (2) air dry aggregates, and (3) intact soils to quantify stress transmission and compaction-resulted soil structure at the same time. Stress transmission was quantified using both X-ray CT and Tactilus sensor mat, and soil-pore structure was quantified using X-ray CT. Our results imply that stress transmission through soil highly depends on the magnitude of applied load and aggregate strength. As soon as the applied load is lower than the aggregate strength, the mode of stress transmission is discrete as stresses were mainly transmitted through chain of aggregates. With increasing applied load soil aggregates start deforming that transformed heterogeneous soil into homogenous, as a result stress transmission mode was shifted from discrete towards more like a continuum. Continuum-like stress transmission mode was better simulated with Boussinesq (1885) model based on theory of elasticity compared to discrete. The soil-pore structure was greatly affected by increasing applied stresses. Total porosity was reduced 5-16% and macroporosity 50-85% at 620 kPa applied stress for the intact soils. Similarly, significant changes in the morphological indices of the macropore space were also observed with increasing applied stresses.

    This document presents the results of a study conducted by the US Nuclear Regulatory Commission of an unobtrusive, voluntary, anonymous third-party managed, nonpunitive human factors data gathering system (the Nuclear power Safety Reporting System - NPSRS) for the nuclear electric power production industry. The data to be gathered by the NPSRS are intended for use in identifying and quantifying the factors that contribute to the occurrence of significant safety incidents involving humans in nuclear power plants. The NPSRS has been designed to encourage participation in the System through guarantees of reporter anonymity provided by a third-party organization that would be responsible for NPSRS management. As additional motivation to reporters for contributing data to the NPSRS, conditional waivers of NRC disciplinary action would be provided to individuals. These conditional waivers of immunity would apply to potential violations of NRC regulations that might be disclosed through reports submitted to the System about inadvertent, noncriminal incidents in nuclear plants. This document summarizes the overall results of the study of the NPSRS concept. In it, a functional description of the NPSRS is presented together with a review and assessment of potential problem areas that might be met if the System were implemented. Conclusions and recommendations resulting from the study are also presented. A companion volume (NUREG/CR-4133, Nuclear Power Safety Reporting System: Implementation and Operational Specifications'') presented in detail the elements, requirements, forms, and procedures for implementing and operating the System. 13 refs

    This study aimed to evaluate the hearing screening of pre-school children at nursery schools in Tyrol, Austria. 47 nursery schools with a total of 2199 enrolled children participated in the study. At the screening, the children were presented a series of tones at frequencies 0.5 kHz (25dB), 1 kHz, 2 kHz, 3 kHz, and 4 kHz (20 dB each) from portable audiometers. The tones were presented over headphones for each ear separately and at irregular intervals. Failure to respond to any of the frequencies was considered failure of the screening. Parents were then advised in written form to have the child examined by an ENT-specialist. 1832 individuals were screened (coverage: 83% of nursery school children; corresponding to at least 63% of all Tyrolean children aged 3 to 5 years). Of these, 390 failed the test (referral rate: 21% of all screened). Examination through an ENT-specialist occurred with 217 children, and this confirmed the positive test in 139 children (hit rate: 64%). In most cases, a temporary conductive hearing loss due to external or middle ear problems (glue ear, tube dysfunction, cerumen, otitis media) was diagnosed. A sensorineural hearing loss was found in 4 children (in 3 of them bilateral). The need for therapy was recognized in 81 children (4% of all screened). Pre-school hearing screening identifies children with ear and hearing problems that need therapeutical intervention. Although the hearing problems are mostly of a temporary nature, some may require monitoring over some period. Also some children with permanent sensorineural hearing loss may be detected through this measure. Hearing screening is an efficient means of assessing ear and hearing problems in pre-school children. However, the follow-up rate needs to be improved for optimizing the efficacy.

    Full Text Available Aim: We aimed to evaluate the clinical and radiological results of an intramedullary fixation system used in surgeries for fractures and deformities of osteogenesis imperfecta where we applied a new design corkscrew tipped intramedullary nailing. Materials and Methods: Twenty extremities of 14 osteogenesis cases, who underwent surgery and to whom corkscrew tipped intramedullary treatment was applied, were retrospectively scanned. Ambulation, discrepancies in the lenght of extremities, deformities and joint mobility range were all noted before the operation. Postoperative union rates, complications and our experience regarding the nail were also evaluated. Results: Six tibia and 14 femurs were operated using corkscrew tipped telescopic nails. Two bones were operated due to non-union, while seven bones underwent surgery due to acute fractures and 11 bones due to deformities. All the bones were seen to have achieved the aimed union. No major complications were observed. Infection was present in two cases. Conclusion: Corkscrew tipped telescopic nail is a safe and effective method of fixation in patients with osteogenesis imperfecta.

    Purpose: To evaluate the short and long-term effects of total lymphoid irradiation (TLI) in the treatment of cardiac transplant rejection. Methods and Materials: Between 1986 and 1995, 48 courses of TLI were delivered to 47 cardiac transplant patients. In 37 patients, TLI was administered for intractable allograft rejection despite conventional therapy while 10 patients received TLI prophylactically. The prescribed radiation dose was 8 Gy in 0.8 Gy fractions twice weekly to mantle and inverted-Y plus spleen fields. Postirradiation follow-up ranged from 6 months to 9.1 years, with a mean of 3.1 years. Results: The actual mean dose was 7.3 Gy delivered over a mean of 39 days. Fifty-six percent of patients required treatment delay or abbreviation because of thrombocytopenia, leukopenia, infection, or unrelated problems. In patients treated for intractable rejection, rejection rates dropped from 0.46 to 0.14 and to 0.06 episodes/patient/month before, during, and after TLI (p < 0.0001). Rejection rates continued to drop throughout follow-up. Prednisone requirements decreased from 0.41 mg/kg before treatment to 0.21 mg/kg afterward (p < 0.0001). The ratio of helper to cytotoxic-suppressor T-cells decreased during TLI from 1.33 to 0.89, and remained low at 0.44, 2-4 months after treatment. Infection rates were not increased and two patients developed malignancy. Rejection rates were high during prophylactic treatment and this protocol was abandoned. Three-year actuarial survival after irradiation was 60% for patients with intractable rejection and 70% for the prophylactic cohort. Conclusion: TLI is an effective treatment for control of intractable cardiac rejection. Episodes of rejection and steroid dosage requirements are decreased for up to 9.1 years. A possible mechanism of action is long term alteration in T-lymphocyte subsets. Patients experience transient bone marrow suppression but no increase in infection or bleeding. Long-term complications of TLI are not

    To determine the results of "biologic fixation" with a minimally invasive plating technique using a newly designed low profile "Scallop" plate in the treatment of pilon fractures. Retrospective case series. A tertiary referral center. Seventeen patients were treated between 1999 and 2001 for a tibial plafond fracture at the Hospital for Special Surgery with a newly designed low-profile plate. Eleven of the fractures (65%) were high-energy injuries. Two fractures were open. Staged surgical treatment with open reduction and fixation of the fibular fracture and application of an external fixator was performed in 12 cases. As soon as the soft tissues and swelling allowed, i.e. skin wrinkling, the articular surface was reconstructed and simply reduced, if necessary through an small incision, and the articular block was fixed to the diaphysis using a medially placed, percutaneously introduced flat scallop plate. In the remaining five cases the operation was performed in one session. Time to healing and complications including delayed union, non-union, instrument failure, loss of fixation, infection, quality of reduction and number of reoperations were evaluated. Quality of results and outcome were graded using the ankle-hindfoot-scale and a modified rating system. All patients went on to bony union at an average time of 14 weeks. There were no plate failures or loss of fixation/reduction. Two superficial wound-healing problems resolved with local wound care. At an average follow up of 17 months (range 6-29 months) eight patients (47%) had an excellent result; seven (41%) had a fair result whereas two (12%) had a poor result. The average ankle-hindfoot-score was 86.1 (range 61-100). Four patients have had the hardware removed and one of them is awaiting an ankle arthrodesis. Based on these initial results, it appears that a minimally invasive surgical technique including new low profile plate can decrease soft tissue problems while leading to fracture healing and

    ensure adequate buffer properties even after suffering from severe erosive mass loss. With these fixed parameters a thorough set of experiments was planned and performed at B+Tech to test the erosive properties of chosen buffer materials in different groundwater conditions. The test method was chosen to be a pinhole erosion test with two size-scales; 100 mm and 400 mm of cell length. In the pinhole test the material is compacted to a certain fixed density as a cylindrical block with a fixed diameter hole at the center axis of the block. The purpose of the pinhole tests was to test the scenario where piping channel has been formed in the buffer in the deposition hole and water flows through a single channel. Test duration depended on the test geometry, for smaller samples durations from 55-200 hours were logged, for larger samples test duration was approx. 200 hours in every case. Several issues enhancing the quality of measurements were considered and developments employed. The repeatability was ensured by carefully documenting every step of the testing process starting from the sample manufacturing to the sample dismantling. In addition, tests were performed with repetitions to yield better reliability and to gain information on the general scatter/noise in the results. Verification of the overall mass loss was performed by measuring the residual mass in the sample cells. Identical measurement run in parallel provided information on the deviation of the results and careful examination of the environmental parameters revealed 2 major problems: 1. Measurement solutions mimicking the groundwater composition are prepared with laboratory grade NaCl and CaCl 2 salts. The standard clay sample drying procedure of heating the sample in 105 C oven for 24 hours is assumed to result water-free clay that contains only the residual salts that are not evaporated during the drying and hence can easily deducted if the original solution salt contents are known.

    PurposeTo evaluate the predictors of toxicity of drug-eluting beads loaded with irinotecan (DEBIRI) in the treatment of hepatic malignancies.Materials and MethodsA total of 330 patients were enrolled in a prospective, open-label, multicenter, multinational, single-arm study administering two types of drug-eluting beads (DEBIRI and drug-eluting beads loaded with doxorubicin). Complications were graded by Cancer Therapy Evaluation Program's Common Terminology Criteria for Adverse Events (CTCAE) version 3.0. All events requiring additional physician treatment or requiring extended hospital stay or readmission within 30 days were included.ResultsA total of 109 patients received 187 DEBIRI treatments (range 1 to 5 per patient). The most common histology was metastatic colorectal cancer in 76% of patients, cholangiocarcinoma in 7% of patients, and other metastatic disease in 17% of patients. There were 35 patients (19%) with irinotecan treatments who sustained 158 treatment-related adverse events, with the median CTCAE event grade being CTCAE grade 2 (range 1 to 5). The most common adverse events were postembolic symptoms (42%). Multivariate analysis identified pretreatment and treatment-related risk factors as follows: lack of pretreatment with hepatic arterial lidocaine (p = 0.005), ≥3 treatments (p = 0.05), achievement of complete stasis (p = 0.04), treatment with >100 mg DEBIRI in 1 treatment (p = 0.03), and bilirubin >2.0 μg/dl with >50% liver involvement (p = 0.05). These factors were predictive of adverse events and significantly greater hospital length of stay.ConclusionsDEBIRI is safe when appropriate technique and treatment are used. Adverse events can be predicted based on pretreatment- and treatment-related factors, and their occurrence can become part of the informed consent process. Continued standardization of this treatment will lead to fewer adverse events and improved patient quality of life.

    Malignant external otitis (MEO) is a potentially fatal otitis occurring in diabetic and immunosuppressed patients, which may cause cranial nerve palsies and massive thrombophlebitis of the brain. We studied five diabetic patients with the clinical diagnosis of external otitis who were suspected of having MEO and one diabetic patient presumed cured from MEO. All of them underwent methylene diphosphonate, nanocolloid and gallium single-photon emission tomography studies with quantitative analysis on the basis of regions of interest and count profile curves. This combined assessment helped us to diagnose and follow-up soft tissue and temporal bone infection, especially in the case of transsphenoidal extension of the disease, since conventional radiology and computed tomography were of no particular help. On the basis of these results, we consider scintigraphic demonstration of skull base infection as a fourth criterion of MEO given that the classical Chandler's triad (diabetes, granuloma, and Pseudomonas aeruginosa) is not always present.

    1978-05-01

    The method described starts from the requirement that the quantitative statement of a measuring result in dosimetry should contain at least three figures: 1) the measured value or the best estimate of the quantity to be measured, 2) the uncertainty of this value given by a figure, which indicates a certain range around the measured value, and which is strongly linked with 3) a figure for the confidence level of this range, i.e. the probability that the (unknown) correct value is embraced by the given uncertainty range. How the figures 2) and 3) can be obtained and how they should be quoted in calibration certificates is the subject of these lectures. In addition, the means by which the method may be extended on determining the uncertainty of a measurement performed under conditions which deviate from the calibration conditt ions is briefly described.

    2009-01-01

    Introduction In breast conserving therapy (BCT) of breast cancer, cosmetic results have become next to tumor-related outcome parameters a criterion of increasing awareness. The aim of this study is the evaluation of long term cosmetic results after conservative surgery and intraoperative radiotherapy with 10 Gy electrons (IOERT), followed by whole breast radiotherapy (WBRT) with 50-54 Gy. Patients and Methods From October 1998 to October 2005, 818 patients (median age 57.89 years) were treated by IOERT during breast conserving surgery, 12 of them for bilateral cancer. 32 patients were referred to mastectomy within primary treatment, 50 were reported as dead at the beginning of the study, 4 patients had developed an in-breast-recurrence and had been salvaged by secondary mastectomy, and in 41 cases an intercurrent dissemination was noted. All 679 remaining patients were invited in written form to participate in the cosmesis study. 403 of them (59.4%) have answered and were object of the evaluation (August 2006 to April 2007). To provide reproducible examination conditions, a standardized photo-documentation in four positions (frontal, loose-hanging and elevated arms; left and right lateral, elevated arms) was accomplished. Patients and treating physicians evaluated the cosmetic results separately within a 5-point-score (Excellent, Good, Moderate, Bad, Complications). Patient-, tumor- and treatment-related factors were investigated with regard to possible impact on the cosmetic outcome in all patients (group 1). A separate subgroup analysis was carried out for 261 patients with a follow-up of at least three years after completion of local treatment (group 2). For computation of the statistic correlation between the variables and the cosmetic evaluation the rank correlation coefficients Kendall's τ Spearman's ρ were used. A correlation is significant below a p-value of 0.05. Results The self-assessment of the patients in group 1 yielded around 69% excellent, 25

    To assess the impact of a positive behavioral reinforcement intervention on psychosocial functioning of inmates over the course of treatment and on post-treatment self-reported measures of treatment participation, progress, and satisfaction. Male ( n = 187) and female ( n = 143) inmates participating in 12-week prison-based Intensive Outpatient (IOP) drug treatment were randomly assigned to receive standard treatment (ST) or standard treatment plus positive behavioral reinforcement (BR) for engaging in targeted activities and behaviors. Participants were assessed for psychosocial functioning at baseline and at the conclusion of treatment (post-treatment). Self-reported measures of treatment participation, treatment progress, and treatment satisfaction were also captured at post-treatment. The intervention affected female and male subjects differently and not always in a way that favored BR subjects, as compared to the ST subjects, most notably on measures of depression and criminal thinking. Possible explanations for the results include differences in the male and female custody environments combined with the procedures that study participants had to follow to earn and/or receive positive reinforcement at the two study sites, as well as baseline differences between the genders and a possible floor effect among females on measures of criminality. Limitations of the study included the inability to make study participants blind to the study conditions and the possible over-branding of the study, which may have influenced the results.

    2012-06-01

    Full Text Available Worldwide, algal biofuel research and development efforts have focused on increasing the competitiveness of algal biofuels by increasing the energy and financial return on investments, reducing water intensity and resource requirements, and increasing algal productivity. In this study, analyses are presented in each of these areas—costs, resource needs, and productivity—for two cases: (1 an Experimental Case, using mostly measured data for a lab-scale system, and (2 a theorized Highly Productive Case that represents an optimized commercial-scale production system, albeit one that relies on full-price water, nutrients, and carbon dioxide. For both cases, the analysis described herein concludes that the energy and financial return on investments are less than 1, the water intensity is greater than that for conventional fuels, and the amounts of required resources at a meaningful scale of production amount to significant fractions of current consumption (e.g., nitrogen. The analysis and presentation of results highlight critical areas for advancement and innovation that must occur for sustainable and profitable algal biofuel production can occur at a scale that yields significant petroleum displacement. To this end, targets for energy consumption, production cost, water consumption, and nutrient consumption are presented that would promote sustainable algal biofuel production. Furthermore, this work demonstrates a procedure and method by which subsequent advances in technology and biotechnology can be framed to track progress.

    Of the five secondary tubes failed in Test A-3, two were failed by impingement wastage, and the other three appear to have been caused by overheating possibly augmented by wastage. Since no secondary tube failures occurred during large leak tests, this spports the hypthesis that a small initial leak can create much more damage on neighboring tubes than an initial large leak. The overheating falures occurred in about 20 seconds after a second large hole had been produced in a thin wall (non-prototypical) primary tube. Continued water injection under static or low sodium flow conditions following an initial small leak will produce high temperatures which can result in deformation (bowing) of 2-1/4 Cr-1 Mo steam tubes and interference at the tube-tubespacer interface. The damage caused by either impingement wastage or overheating will occur at or above the elevation plane of the initial leak. If water/steam injection continues after removal of the sodium, water steam blanketing will cool the tubes heated by the SWR. Additional tube failures can be caused by overheating prior to rupture disc operation when leak rate is increased by secondary tube penetrations caused by wastage. Acoustic emission measurement provides a rapid means of leak detection for intermediate size leaks

METHODS: In this study we evaluated 36 shoulders of 31 patients with OAS who underwent treatment with PSA in the Grupo de Ombro e Cotovelo (Group of Shoulders and Elbows of the Department of Traumatology and Orthopedics of the Faculdade de Ciências Médicas da Santa Casa de São Paulo - Pavillion Fernandinho Simonsen between January, 1989 and November, 2010. Patients who underwent PSA and who had a post-operative follow-up of at least 12 months were included in the study. RESULTS: After the surgery the range of elevation, external rotation, internal rotation and the UCLA scale improved (with average differences of 35º, 27º, 4ºand 17 points, respectively, with a significant level of 5% (p < 0.05. For the same level of significance, the relation between a satisfactory UCLA and two variables was found: patients with maximum age of 60 years old at the moment of the surgery and patients that underwent tenotomy of the long head of biceps. CONCLUSION: Patients under 60 who underwent surgery and patients who underwent tenotomy of the long head of biceps achieved better results.

    Modern surgery as elbow arthroscopic surgery is an accepted operation due to benefit in precise intra-articular lesion detection and minimally invasive surgery. To report the functional results when using arthroscopic surgery to treat chronic lateral elbow pain. The data was collected from 25 patients with chronic lateral elbow pain that failed in non-operative treatment and treated with elbow arthroscopic surgery. Five patients were excluded from this study due to diagnosed as instability that needed the ligament reconstruction. The etiology of pain were grouped in to tennis elbow (4 pts), plica (9 pts), tennis elbow combined with plica (4 pts) and cartilage lesion (3 pts). Thai quick DASH questionnaire was used to evaluate the functional results by comparing pre and post operation score and calculated statistic results with paired t-test by level of significance p tennis elbow mean score was 74 and 33, in plica lesion mean score was 65 and 11, combined lesions mean score was 60 and 18 and cartilage lesion mean score was 60 and 20. Approaching chronic lateral elbow pain with arthroscopy can maintain the signficant improvement of functional result in midterm follow-up.

  19. Evaluation and treatment of malignant ascites secondary to gastric cancer.

    2015-10-21

    Malignant ascites affects approximately 10% of patients with gastric cancer (GC), and poses significant difficulties for both patients and clinicians. In addition to the dismal general condition of affected patients and the diversity of associated complications such as jaundice and ileus, problems in assessing scattered tumors have hampered the expansion of clinical trials for this condition. However, the accumulation of reported studies is starting to indicate that the weak response to treatment in GC patients with malignant ascites is more relevant to their poor prognosis rather than to the ascites volume at diagnosis. Therefore, precise assessment of initial state of ascites, repetitive evaluation of treatment efficacy, selection of suitable treatment, and swift transition to other treatment options as needed are paramount to maximizing patient benefit. Accurately determining ascites volume is the crucial first step in clinically treating a patient with malignant ascites. Ultrasonography is commonly used to identify the existence of ascites, and several methods have been proposed to estimate ascites volume. Reportedly, the sum of the depth of ascites at five points (named "five-point method") on three panels of computed tomography images is well correlated to the actual ascites volume and/or abdominal girth. This method is already suited to repetitive assessment due to its convenience compared to the conventional volume rendering method. Meanwhile, a new concept, "Clinical Benefit Response in GC (CBR-GC)", was recently introduced to measure the efficacy of chemotherapy for malignant ascites of GC. CBR-GC is a simple and reliable patient-oriented evaluation system based on changes in performance status and ascites, and is expected to become an important clinical endpoint in future clinical trials. The principal of treatment for GC patients with ascites is palliation and prevention of ascites-related symptoms. The treatment options are various, including a

    We evaluated the treatment results of acoustic neuromas in the era of radiosurgery. We treated acoustic neuromas using the following strategy. Small to medium size tumors (below 3 cm) were treated by gamma knife radiosurgery and large tumors (above 3 cm) were treated using a combination of surgery and radiosurgery. Using gamma knife radiosurgery we were able to achieve 96.4% of clinical tumor growth control with 0.7% incidence of trigeminal neuropathy (without new facial neuropathy). We used low dose radiosurgery (average tumor marginal dose 11.8 Gy) with a follow-up of an average of 54 months. For the 17 patients with large tumors treated by the combination of surgery and radiosurgery who could be followed up for over 24 months after radiosurgery, we were able to preserve normal facial function (House-Brackmann grade I-II) in 70.6% of the patients after subtotal removal. High clinical tumor growth control for residual tumor was achieved in 94.1% of subjects with an average of 40 months follow-up. By using this strategy, the treatment outcome for acoustic neuroma is improved from the standpoint of functional outcome and maintaining the patient's quality of life. (author)

    Rasagiline (Azilect) is a potent, highly selective and irreversible inhibitor of monoamine oxidase type B of the second generation. Rasagiline is indicated for the treatment of Parkinson's disease (PD) as monotherapy (without levodopa) or as adjunct therapy (with levodopa) in patients with end of dose fluctuations. The efficacy and tolerability of rasagiline has been demonstrated in large-scale, controlled clinical studies in patients with early PD as well as with more advanced PD. This multicentred post-marketing observational study included an investigation of the efficacy and tolerability of rasagiline in a large patient population under conditions of the daily routine in neurologic practice with a special attention on the collection of data regarding a patients' subjective evaluation of quality of life. A total of 754 patients with Parkinson's disease were enrolled, 545 of the patients (63% male patients, mean age 68 years, mean duration of PD 6 years, Hoehn & Yahr stage II to III in 69% of the patients) started rasagiline 1 mg/day as adjunct therapy for up to 4 months. The PD symptoms were rated by the physicians using the Columbia University Rating Scale (CURS) and the clinical fluctuations subscale of the Unified Parkinson's Disease Rating Scale (UPDRS, part IV B). Different aspects of quality of life were rated by the patients using the self-rating Parkinson's Disease Questionaire (PDQ-39). In addition, patients documented the number of hours spend in the OFF-state in "24-hour" home diaries prior to each of the assessment visits. During the treatment period rasagiline was most frequently co-administered with levodopa/DCI (81.7%) and/or dopamine agonists (65.8%). The mean treatment duration was 117.4 (+/-36.4) days, during which PD medication remained unchanged in 86.6% of the cases. The improvement rates in each of the CURS items ranged between 31.1% to 48.4% and the total score was reduced by 22% under the therapy of rasagiline. In the motor part (tremor

    Full Text Available The aim of this study was to conduct a cost-utility study of adefovir, entecavir, interferon alpha, pegylated interferon alpha, lamivudine and tenofovir for chronic hepatitis B in the context of Brazilian Public Health Care System. A systematic review was carried out for efficacy and safety. Another review was performed to collect utility data and transition probabilities between health states. A Markov model was developed in a time horizon of 40 years with annual cycles for three groups of: HBeAg positive, HBeAg negative, and all patients. These strategies were compared to a fourth group that received no treatment. Discount rates of 5% were applied and sensitivity analyses were performed. Tenofovir offered the best cost-utility ratio for the three evaluated models: U$397, U$385 and U$384 (per QALY, respectively, for HBeAg positive, negative, and all patients. All other strategies were completely dominated because they showed higher costs and lower effectiveness than tenofovir. The sequence of cost-utility in the three models was: tenofovir, entecavir, lamivudine, adefovir, telbivudine, pegylated interferon alpha, and interferon alpha. In the sensitivity analysis, adefovir showed lower cost-utility than telbivudine in some situations. The study has some limitations, primarily related to the creation of scenarios and modeling. In this study, tenofovir presented the best cost-utility ratio. The results obtained in this study will be valuable in decision-making and in the review of the clinical protocol, mainly involving the allocation of available resources for health care.

    Technical developments have now made it possible to emplace granular zero-valent iron (Fe 0) in fractured media to create a Fe 0 fracture reactive barrier (Fe 0 FRB) for the treatment of contaminated groundwater. To evaluate this concept, we conducted a laboratory experiment in which trichloroethylene (TCE) contaminated water was flushed through a single uniform fracture created between two sandstone blocks. This fracture was partly filled with what was intended to be a uniform thickness of iron. Partial treatment of TCE by iron demonstrated that the concept of a Fe 0 FRB is practical, but was less than anticipated for an iron layer of uniform thickness. When the experiment was disassembled, evidence of discrete channelised flow was noted and attributed to imperfect placement of the iron. To evaluate the effect of the channel flow, an explicit Channel Model was developed that simplifies this complex flow regime into a conceptualised set of uniform and parallel channels. The mathematical representation of this conceptualisation directly accounts for (i) flow channels and immobile fluid arising from the non-uniform iron placement, (ii) mass transfer from the open fracture to iron and immobile fluid regions, and (iii) degradation in the iron regions. A favourable comparison between laboratory data and the results from the developed mathematical model suggests that the model is capable of representing TCE degradation in fractures with non-uniform iron placement. In order to apply this Channel Model concept to a Fe 0 FRB system, a simplified, or implicit, Lumped Channel Model was developed where the physical and chemical processes in the iron layer and immobile fluid regions are captured by a first-order lumped rate parameter. The performance of this Lumped Channel Model was compared to laboratory data, and benchmarked against the Channel Model. The advantages of the Lumped Channel Model are that the degradation of TCE in the system is represented by a first

    Proximal humeral fractures are common lesions; there is no generally accepted strategy about the treatment for displaced and unstable two- to four-part fractures. We have nowadays many different surgical solutions, ranging from percutaneous pinning to shoulder arthroplasty. Percutaneous plating can be a good solution to treat some of these fractures using a minimally invasive technique and performing stable fixation that can allow early mobilization. Purpose of this paper is to evaluate the results of our first cases of percutaneous plating in proximal humeral fractures in order to assess the theoretical advantages and the incidence of possible complications. From June 2009 to February 2012, we treated 29 proximal humeral fractures with a percutaneous plating (NCB-PH plate) through an anterolateral deltoid split. For each patient, we evaluated the clinical outcome according to Constant score and the radiographic results, paying attention to fracture healing, loss of reduction, hardware complications, and head necrosis. The clinical evaluation gave a mean Constant score value of 79 points. Comparing each value to the unaffected shoulder, we could find these results: 7 excellent, 10 good, 8 fair, and 4 poor. No axillary nerve lesions were clinically detected. The radiographic evaluation showed a complete bone healing in all cases within the first 3 months. No head necrosis was detected, as well as screws loosening. In two cases, the X-ray at 2 months revealed a little loss of reduction in varus. Two patients had an anterior pain; in one of these two cases, the plate was removed. In our series, we had no cases of head necrosis, screws cutout, fracture collapse, hardware mobilization, and we think this could be the real advantage of the percutaneous technique compared to the open one, thanks to the reduced biological damage. We had some poor results, related more to patient's age than to other factors. The safety of the technique for the axillary nerve is

    The treatment strategy for skull base meningiomas remains a controversial issue. Because of the proximity of these tumours to critical neurovascular structures, the risk for vascular damage and new cranial neuropathies postoperatively is significant. To avoid unacceptable neurological deficits the surgical treatment strategy includes different surgical approaches and a subtotal removal of these tumours in some cases. However, because the rate of recurrence and progression is significant in these patients, a demand for adjuvant treatment and better prognostic methods is called for so that treatment and follow-up can be tailored to each patient. Accordingly, we have chosen to evaluate general outcome and facial nerve function after translabyrinthine and transcochlear approaches for cerebellopontine angle (CPA) meningiomas. Furthermore, we have evaluated two adjuvant treatments, namely, irradiation by high-energy proton beams and medical treatment with interferon-alpha as well as evaluation of the treatment effect with 11 C-L-methionine PET. In addition, we have evaluated a new PET tracer ( 76 Br-BrdU) for 'in vivo' determination of the growth potential of intracranial tumours. Conclusion: The translabyrinthine and transcochlear approaches are apparently safe surgical procedures in the treatment of CPA meningiomas. Proton beam therapy is technically feasible as suggested by the fact that only minimal side effects were observed. Moreover, none of the meningiomas treated have shown progression during a 36-month follow-up. Our results indicate that IFN-alpha can be an effective oncostatic treatment for certain patients with meningiomas. The 11 C-L-methionine PET method might be used as a complement to CT or MRI in the evaluation of the effect of proton beam and IFN-alpha treatment in meningiomas. The present attempt failed to demonstrate that the PET tracer 76 Br-BrdU could be used for the non-invasive characterisation of growth potential in brain, tumours

    Since the introduction of modern surgical techniques and monitoring tools for the treatment of severe traumatic brain injury (TBI) in Switzerland, standardized nationwide operative procedures are still lacking. This study aimed to assess surgical management and monitoring strategies in patients admitted throughout Switzerland with severe TBI. Demographic, clinical, and radiologic data from a prospective national cohort study on severe brain-injured patients (Patient-relevant Endpoints after Brain Injury from Traumatic Accidents [PEBITA]) were collected during a 3-year period. This study evaluated patients admitted to 7 of the 11 trauma centers included in PEBITA. We retrospectively analyzed surgery-related computed tomography (CT) findings prior to and after treatment, intracranial pressure (ICP) monitoring, size and technical features of craniotomy, as well as surgical complications. ResULTS: This study included 353 of the 921 patients enrolled in PEBITA who underwent surgical treatment for severe TBI. At admission, acute subdural hematoma was the most frequent focal lesion diagnosed (n = 154 [44%]), followed by epidural hematoma (n = 96 [27%]) and intracerebral hematoma (n = 84 [24%]). A total of 198 patients (61%) presented with midline shift. Clinical deterioration in terms of Glasgow Coma Scale scores or intractable ICP values as an indication for surgical evacuation or decompression were documented in 20% and 6%, respectively. A total of 97 (27.5%) only received a catheter/probe for ICP monitoring. Surgical procedures to treat a focal lesion or decompress the cerebrum were performed in 256 patients (72.5%). Of the 290 surgical procedures (excluding ICP probe implantation), craniotomy (137 [47.2%]) or decompressive craniectomy (133 [45.9%]) were performed most frequently. The mean size of craniectomy in terms of maximal linear width on the CT axial slice was 8.4 ± 2.9 cm. Intraoperative ICP monitoring was reported in 61% of the interventions. Significant

    A wastewater treatment plant has been established in Khartoum Refinery Company in order to treat 1800 meters cubic per day, and to meet the increase in the number of employees and the continued expansion of the company. The study aims to evaluate the performance of the station after a three years period of work, and calculate the efficiency of the station through the following variables: average removal of the biological oxygen demand, chemical oxygen demand, suspended solids and oils, by taking water samples before and after treatment, every week for two month, analysis of samples were conducted in the central laboratory at KRC. The determination of the station efficiency revealed that the station is working well. Treated water characteristics are in conformity with the specifications set by the world Organization Health. It is also proved to be suitable for use in irrigation the amount of water entering to treatment is very large (1500 cubic meters), which lead to dilution of the BOD, COD, SS and oils concentrations. The reason being misuse of water by employees in addition to the large number of damage in the water pipes. The station must be re-evaluated after a certain (5 years) period to determine the impact of future increases of employees, and it is effect on the efficiency of the station. It is recommended to improve the behaviour of employees regarding the use of water, so as to reduce the dilution. (Author)

    Craniopharyngioma is a rare primary central nervous system neoplasm. Our objective was to determine factors associated with incidence, treatment, and survival of craniopharyngiomas in the United States. We used the surveillance, epidemiology and end results program (SEER) database to identify patients who received a diagnosis of craniopharyngioma during 2004–2008. We analyzed clinical and demographic information, including age, race, sex, tumor histology, and treatment. Age-adjusted incidence rates and age, sex, and race-adjusted expected survival rates were calculated. We used Cox proportional hazards models to determine the association between covariates and overall survival. We identified 644 patients with a diagnosis of craniopharyngioma. Black race was associated with an age-adjusted relative risk for craniopharyngioma of 1.26 (95% confidence interval [CI], 0.98–1.59), compared with white race. One- and 3-year survival rates of 91.5% (95% CI, 88.9%–93.5%), and 86.2% (95% CI, 82.7%–89.0%) were observed for the cohort; relative survival rates were 92.1% (95% CI, 89.5%–94.0%) and 87.6% (95% CI, 84.1%–90.4%) for 1- and 3-years, respectively. In the multivariable model, factors associated with prolonged survival included younger age, smaller tumor size, subtotal resection, and radiation therapy. Black race, on the other hand, was associated with worse overall survival in the final model. We demonstrated that >85% of patients survived 3 years after diagnosis and that subtotal resection and radiation therapy were associated with prolonged survival. We also noted a higher incidence rate and worse 1- and 3-year survival rates in the black population. Future investigations should examine these racial disparities and focus on evaluating the efficacy of emerging treatment paradigms. PMID:22735773

    Many patients with breast cancer work for pay at the time of their diagnosis, and the treatment plan may threaten their livelihood. Understanding work experiences in a contemporary population-based sample is necessary to inform initiatives to reduce the burden of cancer care. Women who were 20 to 79 years old and had been diagnosed with stage 0 to II breast cancer, as reported to the Georgia and Los Angeles Surveillance, Epidemiology, and End Results registries in 2014-2015, were surveyed. Of the 3672 eligible women, 2502 responded (68%); 1006 who reported working before their diagnosis were analyzed. Multivariate models evaluated correlates of missing work for >1 month and stopping work altogether versus missing work for ≤1 month. In this diverse sample, most patients (62%) underwent lumpectomy; 16% underwent unilateral mastectomy (8% with reconstruction); and 23% underwent bilateral mastectomy (19% with reconstruction). One-third (33%) received chemotherapy. Most (84%) worked full-time before their diagnosis; however, only 50% had paid sick leave, 39% had disability benefits, and 38% had flexible work schedules. Surgical treatment was strongly correlated with missing >1 month of work (odds ratio [OR] for bilateral mastectomy with reconstruction vs lumpectomy, 7.8) and with stopping work altogether (OR for bilateral mastectomy with reconstruction vs lumpectomy, 3.1). Chemotherapy receipt (OR for missing >1 month, 1.3; OR for stopping work altogether, 3.9) and race (OR for missing >1 month for blacks vs whites, 2.0; OR for stopping work altogether for blacks vs whites, 1.7) also correlated. Those with paid sick leave were less likely to stop working (OR, 0.5), as were those with flexible schedules (OR, 0.3). Working patients who received more aggressive treatments were more likely to experience substantial employment disruptions.

    Purpose: A retrospective analysis of 38 patients with Peyronie's disease treated with primary radiotherapy in the period of 1975-1993. Methods and Materials: Important complaints were curvature of the penis during erection for 92% of the patients, painful erection for 68%, and problems with sexual intercourse for 37.5%. Average size of all indurated plaques was 2.5 cm. The average pretreatment duration of symptoms was 9.5 months. All 38 patients were irradiated with orthovoltage radiotherapy (200 and 250 kV photons) with a total dose of 9 Gy in 5 alternating days (regimen A). Because of minimal response, 16 patients were irradiated again with another 9 Gy in 5 days and finally received 18 Gy (regimen B). Results: With regimen A, a satisfying improvement was achieved for the majority of the patients: 65% experienced less penile pain during erection, 40% reported less curvature of the penis, and 47% experienced an improvement of their sex life. With the higher dose of regimen B there was an additional improvement for a minority of the patients: 25% reported less pain during erection, 21% had less curvature, and 29% experienced an improved sex life. With regimen A, pain improvement was statistically significantly superior when compared to regimen B. For all other improvements (curvature, sexual intercourse, and induration) no dose-response relation could be demonstrated between regimen A and the higher dose regimen B. No patient experienced any radiation-induced morbidity. After evaluating regimen A and regimen B, the overall result was that 76% experienced less pain, 60% reported an improved sex life, and 48% had a diminished curvature during erection. Conclusion: From this analysis it can be concluded that the distressing symptoms of Peyronie's disease can be treated successfully with radiotherapy. Radiotherapy proves to be a safe, noninvasive treatment method without causing morbidity. Low-dose radiotherapy with only a few fractions is recommended for an effective

    Destructive analysis for accountancy at nuclear fuel facilities should attain international target values for measurement uncertainties in safeguarding nuclear materials (ITVs). Since measurement uncertainties of isotope dilution mass spectrometry depend on uncertainties of spikes (standard materials) used, utilizing highly reliable standard material is essential. The LSD spikes prepared under collaboration work with JAEA and JNFL has different Pu/U ratio and smaller nuclear material in a spike compared with the LSD spikes used a safeguard laboratories, and the value of Pu which separated and purified from MOX and used as raw material for one of the LSD spike prepared at JAEA were measured at JAEA. Uncertainties of the prepared LSD spikes and the measurement results of actual samples with these LSD spikes were evaluated based on ISO-GUM and compared with ITVs. (author)

    Full Text Available The aim of this study was to evaluate the reduction in volume of arm lymphedema secondary to breast cancer therapy utilizing an exercise facilitating device. Twenty-one women with arm lymphedema resulting from the surgical and radiotherapeutic treatment of breast cancer were randomly selected. Evaluation was made by water-displacement volumetry before and after each session. The patients were submitted to a series of active exercises using a facilitating device for four 12-minute sessions with intervals of 3 minutes between sessions in the sitting position with alignment of the spinal column. The lymphedematous arm was maintained under compression using a cotton-polyester sleeve. The active exercising device used was a mobile flexion bar fixed on a metal base at a height of 30 cm from the tabletop and at a distance of 10 cm from the patient’s body. The paired t-test was utilized for statistical analysis with an alpha error of 5% (p-value ≤0.05 being considered significant. The initial mean volume of the arms was 2,089.9 and the final volume was 2,023.0 mL with a mean loss of 66.9 mL (p-value <0.001. In conclusion, active exercises utilizing facilitating devices can contribute to a reduction in size of lymphedematous limbs.

    The Mixed Waste Integrated Program (MWIP) is one of several US Department of Energy (DOE) integrated programs established to organize and coordinate throughout the DOE complex the development of technologies for treatment of specific waste categories. The goal of the MWIP is to develop and deploy appropriate technologies for -the treatment of DOE mixed low-level and alpha-contaminated wastes in order to bring all affected DOE installations and projects into compliance with environmental laws. Evaluation of treatment technologies by the MWIP will focus on meeting waste form performance requirements for disposal. Thermal treatment technologies were an early emphasis for the MWIP because thermal treatment is indicated (or mandated) for many of the hazardous constituents in DOE mixed waste and because these technologies have been widely investigated for these applications. An advisory group, the Thermal Treatment Working Group (TTWG), was formed during the program's infancy to assist the MWIP in evaluating and prioritizing thermal treatment technologies suitable for development. The results of the overall evaluation scoring indicate that the four highest-rated technologies were rotary kilns, slagging kilns, electric-arc furnaces, and plasma-arc furnaces. The four highest-rated technologies were all judged to be applicable on five of the six waste streams and are the only technologies in the evaluation with this distinction. Conclusions as to the superiority of one technology over others are not valid based on this preliminary study, although some general conclusions can be drawn

    Full Text Available Background and Aims: Apical root resorption is an adverse side effect of fixed orthodontic treatment which cannot be repaired. The aim of this study was to use panoramic radiographs to compare the root resorption before and after the orthodontic treatment with standard edgewise .018 appliance.Materials and Methods: The before and after treatment panoramic views of sixty-three patients needed fixed orthodontic treatment included 1520 teeth were categorized into 3 Grades (G0: without resorption, G1: mild resorption with blunt roots or ≤ 1/4 of root length, G2: moderate to severe resorption or > 1/4 to 1/2 of root length. Relationship between root resorption and sex and treatment duration was analyzed with Mann-whitney and Spearman's correlation coefficient, respectively.Results: The findings showed that 345 teeth were categorized as Grade 1. Grade 2 of root resorption was not found in this study. The highest amount of root resorption was recorded for the mandibular lateral incisor. In both gender, the root resorption of the mandible was more than that of the maxilla. The males showed significantly higher rate of resorption than the females (P0.05.Conclusion: The mandible and male patients showed higher amount of root resorption. In addition, root resorption was not related to the treatment duration and the side of the jaws.

    Full Text Available Introduction: For fabricating dental prostheses that meet patients' demands and have good longevity and function, appropriate treatment planning and decision-making are required. Therefore, not only technical skills and clinical judgment of the dentist are needed, but also patients' attitude toward treatment plays a critical role in posttreatment satisfaction. Aim: The aim of this study is to investigate the factors affecting decision-making and the selection of dental prosthesis by the patients. Materials and Methods: A cross-sectional survey to determine patients' attitudes about replacement of teeth was conducted. This survey was performed with the help of a prevalidated questionnaire, which contained the demographic data of every patient, whether or not they accept the treatment plan proposed by the dentist, and a close-ended multiple choice question stating the reasons cited by them if they decline the proposed treatment plan. Results: The data were subjected to statistical analysis by Chi-square test at a significance level of P< 0.05. A relationship between the demographical information such as age, gender, educational status, marital status, and monthly income of each patient and the single best reason opted by them to not undergo the proposed treatment plan was established. Conclusions: In the sample of population studied, most of the patients declined the proposed treatment plan and accepted the alternate one. High expenditure is the most common reason for this rejection.

    Introduction: Dysphagia is the main problem in patients with advanced nonresectable esophageal cancer. Palliation can be achieved by several treatment ways. We want to evaluate the efficacy of endoluminal brachytherapy (BT) for improvement of dysphagia, performance status, time of local tumor progress, and survival time. Methods: 6 patients with esophageal cancer stage IV received a palliative treatment with 192 Ir HDR BT. The dose per fraction was 5 Gy, calculated 1 cm from the surface of the applicator, the total dose was 20 Gy (four weekly applications). Symptoms, performance status and life quality score were investigated before each application and each 4 weeks after treatment. The results were compared with 10 historical patients who were treated by implantation of nitinol stents (Ultraflex, Boston Scient. Inc.). Results: The tumor stages in the BT-group were T4, T3, T2 three, two and one, and in the stent group three, two and five, respectively. Dysphagia improved in median from grade 1.7 to grade 0.5 (BT group) and from grade 2.6 to grade 1.8 (stent group). Karnowski status improved in the BT group from 70 % to 85 %, but did not change in the stent group (75%). A strong correlation between improvement of dysphagia and life quality score could be found especially in patients with initial high grade dysphagia. The only side effect of BT mostly after the 3 rd application was esophagitis grade 1 in 3 patients and grade 2 in 1 patient. Relief of the esophagitis after conservative therapy could be achieved within 1 week. In the BT group 3 patients were alive without local progress after 20, 13 and 2 weeks. The other 3 patients died from local progress (2 patients, after 20, 20 weeks) or from metastasis (1 patient, after 11 weeks). All patients in the stent group died from local progress. The median survival time is 17 ± 5.2 weeks in BT group vs. 8.8 ± 8.6 weeks in the stent group. Conclusion: Endoluminal brachytherapy seems to be an effective and well tolerable

    This study examined the inactivation of human norovirus (HuNoV) GI.1 and GII.4 by chlorine under conditions mimicking sewage treatment. Using a porcine gastric mucin-magnetic bead (PGM-MB) assay, no statistically significant loss in HuNoV binding (inactivation) was observed for secondary effluent treatments of ≤25 ppm total chlorine; for both strains, 50 and 100 ppm treatments resulted in ≤0.8-log 10 unit and ≥3.9-log 10 unit reductions, respectively. Treatments of 10, 25, 50, and 100 ppm chlorine inactivated 0.31, 1.35, >5, and >5 log 10 units, respectively, of the norovirus indicator MS2 bacteriophage. Evaluation of treatment time indicated that the vast majority of MS2 and HuNoV inactivation occurred in the first 5 min for 0.2-μm-filtered, prechlorinated secondary effluent. Free chlorine measurements of secondary effluent seeded with MS2 and HuNoV demonstrated substantial oxidative burdens. With 25, 50, and 100 ppm treatments, free chlorine levels after 5 min of exposure ranged from 0.21 to 0.58 ppm, from 0.28 to 16.7 ppm, and from 11.6 to 53 ppm, respectively. At chlorine treatment levels of >50 ppm, statistically significant differences were observed between reductions for PGM-MB-bound HuNoV (potentially infectious) particles and those for unbound (noninfectious) HuNoV particles or total norovirus particles. While results suggested that MS2 and HuNoV (measured as PGM-MB binding) behave similarly, although not identically, both have limited susceptibility to chlorine treatments of ≤25 ppm total chlorine. Since sewage treatment is performed at ≤25 ppm total chlorine, targeting free chlorine levels of 0.5 to 1.0 ppm, these results suggest that traditional chlorine-based sewage treatment does not inactivate HuNoV efficiently. IMPORTANCE HuNoV is ubiquitous in sewage. A receptor binding assay was used to assess inactivation of HuNoV by chlorine-based sewage treatment, given that the virus cannot be routinely propagated in vitro Results reported here

    Cirrhotic patients often develop severe complications requiring ICU admission. Grade III-IV hepatic encephalopathy, septic shock, acute-on-chronic liver failure and variceal bleeding are clinical decompensations that need a specific therapeutic approach in cirrhosis. The increased effectiveness of the treatments currently used in this setting and the spread of liver transplantation programs have substantially improved the prognosis of critically ill cirrhotic patients, which has facilitated their admission to critical care units. However, gastroenterologists and intensivists have limited knowledge of the pathogenesis, diagnosis and treatment of these complications and of the prognostic evaluation of critically ill cirrhotic patients. Cirrhotic patients present alterations in systemic and splanchnic hemodynamics, coagulation and immune dysfunction what further increase the complexity of the treatment, the risk of developing new complications and mortality in comparison with the general population. These differential characteristics have important diagnostic and therapeutic implications that must be known by general intensivists. In this context, the Catalan Society of Gastroenterology and Hepatology requested a group of experts to draft a position paper on the assessment and treatment of critically ill cirrhotic patients. This article describes the recommendations agreed upon at the consensus meetings and their main conclusions. Copyright © 2015 Elsevier España, S.L.U. y AEEH y AEG. All rights reserved.

    Following the increasing desire of many patients to keep the form and function of speech and swallowing, interstitial brachytherapy has become the main treatment for head and neck cancer. In addition, aged and physically handicapped patients who are refused general anesthesia have come to be referred to our clinic to receive less invasive and curative treatment. In the field of brachytherapy for head and neck cancers, less complicated and more superior treatment results have been achieved following the introduction of spacers, computer dosimetry and so on. As a result of these efforts, treatment results have come to fulfill the desire of patients and their families. During the past 43 years from 1962 to 2005, we have treated over 2, 100 patients of head and neck cancer including 850 with stage I·II oral tongue carcinoma by brachytherapy and acquired a lot of important and precious data including the treatment results, multiple primary cancers as well as radiation-induced cancers.

    The Arch of Peace, by Luigi Cagnola, is one of the most famous neoclassical monuments in Milan. It has been subjected to conservative intervention in 1998. In the present paper the efficacy of the consolidation by means of barium hydroxide has been evaluated. The stone material showed severe degradation phenomena as: erosion, pulverisation, exfoliation. The analytical data acquired through X-ray diffraction (XRD), infrared spectrophotometry (FTIR) and scanning electron microscopy (SEM-EDX), allowed to compare the conditions of stone before and after the treatment with barium hydroxide. The presence of barium has been put in evidence mainly on the surface as barium sulphate, whereas barium is only sporadically present within the thickness of the decayed material. The treatment was judged not satisfying and its inefficacy is, most probably, due to a not suitable cleaning procedure carried out before the consolidation.

    While anaerobic treatment is capable of treating pharmaceutical wastewater and removing antibiotics in liquid phases, solid phases may still contain significant amounts of antibiotics following this treatment. The main goal of this study was to evaluate the use of white-rot fungi to remove erythromycin, sulfamethoxazole, and tetracycline combinations from biosolids. The degradation potential of Trametes versicolor and Bjerkandera adusta was evaluated via the sequential treatment of anaerobic sludge. Polymerase chain reaction-denaturing gradient gel electrophoresis (PCR-DGGE) analyses were used to identify competition between the autochthonous microbial communities and white-rot fungi. Solid-phase treatment using white-rot fungi substantially reduced antibiotic concentrations and toxicity in sludge. According to PCR-DGGE results, there is an association between species of fungus and antibiotic type as a result of the different transformation pathways of fungal strains. Fungal post-treatment of sludge represents a promising method of removing antibiotic combinations, therefore holding a significant promise as an environmentally friendly means of degrading the antibiotics present in sludge.

    Dysphagia is very common in children with neurological disabilities. These patients usually suffer from respiratory and nutritional problems. The videofluoroscopic swallowing study (VFSS) is the most recommended test to evaluate dysphagia, as it shows the real situation during swallowing. To analyse the results obtained in our centre after one year of the implementation of VFSS, the clinical improvement after confirmation, and the prescription of an individualised treatment for the patients affected. VFSS performed in the previous were collected. The following variables were analysed: age, pathology, degree of neurological damage, oral and pharyngeal and/or oesophageal dysphagia and its severity, aspirations, prescribed treatment, and nutritional and respiratory improvement after diagnosis. A statistical analysis was performed using SPSS v21. A total of 61 VFSS were performed. Dysphagia was detected in more than 70%, being moderate-severe in 58%. Aspirations and/or penetrations were recorded in 59%, of which 50% were silent. Adapted diet was prescribed to 56%, and gastrostomy was performed on 13 (21%) patients. A statistical association was found between neurological disease and severity of dysphagia. The degree of motor impairment is related to the presence of aspirations. After VFSS evaluation and treatment adjustment, nutritional improvement was found in Z-score of weight (+0.3SD) and BMI (+0.4SD). There was respiratory improvement in 71% of patients with dysphagia being controlled in the Chest Diseases Department. After implementation of VFSS, a high percentage of patients were diagnosed and benefited from a correct diagnosis and treatment. VFSS is a fundamental diagnostic test that should be included in paediatric centres as a diagnostic method for children with suspected dysphagia. Copyright © 2017.

    Full Text Available Response of vitiligo patients to five different regimes was evaluated taking only those patients who had either static or progressively increasing lesions. Selection of the regimen depended upon the clinical characteristics of the disease. Each regime was tried for at least 4 months and if a patient didnot improve with one regime, he was shifted to another regime. A patient was considered to have improved, if the lesions started regimenting or the previously progressive lesions stopped increasing further. Regime I consisted of 150 mg levamisol orally on two consecutive days per week, given to 13 cases, it resulted in improvement in 7 (53.80/o. Regime II consisted of levamisole in the same dose combined with once a day topical massage with 0.1% fluocinolone acetonide acetate cream; it led to improvement in 27 (81.8% of the 33 cases. Regime III consisted of 3 mg betamethasone orally on alternate days combined with levamisole and topical fluocinolone; given to 32 cases, it was successful in 28 (87.50/o. A combination of 2 mg betamethasone orally alternating with 20 mg 8-methoxypsoralen and sun exposure (regime IV caused improvement in 17 (85% of the 20 cases. An oral mini pulse consisting of 5 mg betamethasone orally twice a week combined with 50 mg cyclophosphimide daily orally (regime V was successful in 20 (90.9% of the 22 cases, the remaining two cases showed unprovement when the dose ofbetamethasonc .was increased from 5 mg to 7.5 mg twice a week. Thus ultimately each one of the 91 patients responded to one or the other regime. The side effects were minimal and insignificant.The degree of improvement at the time of analysis was 100% in 23.3% cases, 50-100% in 44.2′Yo cases and less than 50% in 32.5%, after 4-14 months of treatment. It is felt that the results may be better after a longer follow-up although all patients are not expected to get complete repigmentation.

    Full Text Available OBJECTIVE: To assess the prevalence of severe external root resorption and its potential risk factors resulting from orthodontic treatment. METHODS: A randomly selected sample was used. It comprised conventional periapical radiographs taken in the same radiology center for maxillary and mandibular incisors before and after active orthodontic treatment of 129 patients, males and females, treated by means of the Standard Edgewise technique. Two examiners measured and defined root resorption according to the index proposed by Levander et al. The degree of external apical root resorption was registered defining resorption in four degrees of severity. To assess intra and inter-rater reproducibility, kappa coefficient was used. Chi-square test was used to assess the relationship between the amount of root resorption and patient's sex, dental arch (maxillary or mandibular, treatment with or without extractions, treatment duration, root apex stage (open or closed, root shape, as well as overjet and overbite at treatment onset. RESULTS: Maxillary central incisors had the highest percentage of severe root resorption, followed by maxillary lateral incisors and mandibular lateral incisors. Out of 959 teeth, 28 (2.9% presented severe root resorption. The following risk factors were observed: anterior maxillary teeth, overjet greater than or equal to 5 mm at treatment onset, treatment with extractions, prolonged therapy, and degree of apex formation at treatment onset. CONCLUSION: This study showed that care must be taken in orthodontic treatment involving extractions, great retraction of maxillary incisors, prolonged therapy, and/or completely formed apex at orthodontic treatment onset.

    As part of its mission to propose innovative and safe technologies to mitigate Primary Water Stress Corrosion Cracking (PWSCC) in Pressurized Water Reactors (PWR), EPRI recently initiated a program to evaluate potential new chemical surface treatments that might delay the occurrence of PWSCC such that no failure of components would be observed during their lifetime. Among the initial screening of more than thirty technologies, seven were selected for a more detailed review. The selected technologies were: nickel and nickel alloy plating, organic inhibitors, chromium-based inhibitors, silicon carbide, titanium-based inhibitors, rare earth metal (REM)-based inhibitors and encapsulation. The conclusions of the review of these technologies were that two of them were worth pursuing, titanium-based and REM-based inhibitors, and that evaluating the radiological consequences of injecting these products in the primary system, as well as assessing their efficacy to mitigate PWSCC, should be prioritized as the next required steps in qualification for implementation.

    2006-01-01

    The diagnosis, evaluation and management of antenatal hydronephrosis has undergone a two stage paradigm shift since the advent of prenatal ultrasonography in the early 1980s. Initially the identification of a large number of asymptomatic infants appeared to afford the surgeon the opportunity for preemptive intervention. However, it has now become apparent that antenatal hydronephrosis (AH) is far more difficult to interpret thanoriginally perceived. The initial enthusiasm for surgery has now been replaced by a much more conservative approach to ureteropelvic junction(UPJ) obstruction, multi-cystic dysplastic kidney(MCDK), vesicoureteral reflux and the non-refluxing megaureter. This review will highlight the postnatal evaluation of AH and include an overview of the Society for Fetal Urology grading system for hydronephrosis. The differential diagnosis and treatment options for UPJ obstruction, vesicoureteral reflux, MCDK, duplication anomalies, megaureter, and posterior urethral valves will be discussed. PMID:17619702

    Management of the unstable shoulder after a failed stabilization procedure can be difficult and challenging. Detailed understanding of the native shoulder anatomy, including its static and dynamic restraints, is necessary for determining the patient's primary pathology. In addition, evaluation of the patient's history, physical exam, and imaging is important for identifying the cause for failure after the initial procedure. Common mistakes include under-appreciation of bony defects, failure to recognize capsular laxity, technical errors, and missed associated pathology. Many potential treatment options exist for revision surgery, including open or arthroscopic Bankart repair, bony augmentation procedures, and management of Hill Sachs defects. The aim of this narrative review is to discuss in-depth the common risk factors for post-surgical failure, components for appropriate evaluation, and the different surgical options available for revision stabilization.

    Full Text Available In Galicia there are supplies that collect water from reservoirs showing growth of cyanobacteria that could produce toxins. The drinking water treatment plants (DWTPs of these supplies should provide adequate treatment and be subjected to maintenance. WHO guidelines make recommendations on the most suitable treatments for removing microcystins. The Department of Health developed a protocol of action against these events jointly with water basin authorities. 4 reservoirs and five treatment plants were identified for this study. The treatments of the plants, the maintenance carried out at the DWTPs and the results for sestonic and dissolved toxins analyzed by the Public Health Laboratory of Galicia in the reservoirs near the point of collection, before the treatment plants and after them, during the 2013-2014 biennium were evaluated.

    In this study, the mechanical properties of a carbon fiber/polypropylene composite were evaluated according to the carbon fiber surface treatment. Carbon fiber surface treatments such as silane coupling agents and plasma treatment were performed to enhance the interfacial strength between carbon fibers and polypropylene. The treated carbon fiber surface was characterized by XP S, Sem, and single-filament tensile test. The interlaminar shear strength (Ilks) of the composite with respect to the surface treatment was determined by a short beam shear test. The test results showed that the Ilks of the plasma-treated specimen increased with the treatment time. The Ilks of the specimen treated with a silane coupling agent after plasma treatment increased by 48.7% compared to that of the untreated specimen

    Declad waste generated by the process of chemical decladding of Al-cladded uranium metal fuel is characterized by highly alkaline, high Al bearing intermediate level waste. It was found that the process developed and adopted in India for plant scale treatment of alkaline intermediate level waste (ILW) is unsuitable for treatment of declad waste. This is mainly due to its exotic characteristics, notably substantial amounts of aluminium in the declad waste. As part of development of treatment scheme for this waste, 137 Cs removal by RFPR has been demonstrated earlier and the present paper reports the results of further processing of the Cs-lean effluent. The waste simulated with respect to the major chemical constituents of stored Al-bearing alkaline ILW after 137 Cs and 90 Sr removal by ion exchange, is used in this study

    Full Text Available Purpose. Aim of the study is to evaluate the efficacy of the endoscopic (pneumatic dilation versus surgical (Heller myotomy treatment in patients affected by esophageal achalasia using barium X-ray examination of the digestive tract performed before and after the treatment. Materials and Methods. 19 patients (10 males and 9 females were enrolled in this study; each patient underwent a barium X-ray examination to evaluate the esophageal diameter and the height of the barium column before and after endoscopic or surgical treatment. Results. The mean variation of oesophageal diameter before and after treatment is −2.1 mm for surgery and 1.74 mm for pneumatic dilation (OR 0.167, CI 95% 0.02–1.419, and P: 0.10. The variations of all variables, with the exception of the oesophageal diameter variation, are strongly related to the treatment performed. Conclusions. The barium X-ray study of the digestive tract, performed before and after different treatment approaches, demonstrates that the surgical treatment has to be considered as the treatment of choice of achalasia, reserving endoscopic treatment to patients with high operative risk and refusing surgery.

    Purpose: To evaluate the short and long term effects of total lymphoid irradiation (TLI) in the treatment of allograft rejection in cardiac transplant patients. Materials and Methods: From 1986 to 1995, 48 courses of TLI were delivered to 47 patients who had received cardiac transplants at Stanford University. In 38 cases, TLI was administered for chronic, intractable allograft rejection despite conventional anti-rejection therapy, including corticosteroids, azathioprine, cyclosporine, OKT3, DHPG, RATG, and methotrexate. Ten patients received TLI prophylactically, beginning radiation between 5 and 16 days after heart transplantation. The prescribed radiation dose was 800 cGy given in 80 cGy fractions twice weekly to all major lymph node regions using mantle and inverted Y fields. Patients continued to receive all medications except azathioprine which was held during TLI to prevent severe marrow suppression. All patients were closely monitored for episodes of rejection, infection, prednisone requirements, blood counts, and complications of treatment. Post-irradiation follow up ranged from 6 months to 9.1 years with a mean of 3.1 years. Results: The actual mean dose of radiation was 730 cGy delivered over a mean of 39 calendar days. Fifty six percent of patients required treatment delay or abbreviation because of thrombocytopenia, leukopenia, infection, or unrelated problems. In patients treated for intractable rejection, the frequency of rejection dropped from 0.46 episodes/patient/month before radiation to 0.14 episodes/patient/month during TLI (p 3 during TLI (p = 0.01) and remained low at 167.6 cells/mm 3 2-4 months after treatment (p = 0.05). CD8+ lymphocytes also decreased during treatment from 233.2 to 65.8 cells/mm 3 (p = 0.003) but rose significantly above normal to 381.3 cells/mm 3 2-4 months after TLI (p 0.05). Thus, the ratio of helper/suppresser T-cells was chronically decreased. Infection rates were not significantly different before, during or after

    Background Sacroiliac joint pain is a common cause of chronic low back pain. Different techniques for radiofrequency denervation of the sacroiliac joint have been used to treat this condition. However, results have been inconsistent because the variable sensory supply to the sacroiliac joint is difficult to disrupt completely using conventional radiofrequency. Cooled radiofrequency is a novel technique that uses internally cooled radiofrequency probes to enlarge lesion size, thereby increasing the chance of completely denervating the sacroiliac joint. The objective of this study was to evaluate the efficacy of cooled radiofrequency denervation using the SInergy™ cooled radiofrequency system for sacroiliac joint pain. Methods The charts of 20 patients with chronic sacroiliac joint pain who had undergone denervation using the SInergy™ cooled radiofrequency system were reviewed at two years following the procedure. Outcome measures included the Numeric Rating Scale for pain intensity, Patient Global Impression of Change, and Global Perceived Effect for patient satisfaction. Results Fifteen of 20 patients showed a significant reduction in pain (a decrease of at least three points on the Numeric Rating Scale). Mean Numeric Rating Scale for pain decreased from 7.4 ± 1.4 to 3.1 ± 2.5, mean Patient Global Impression of Change was “improved” (1.4 ± 1.5), and Global Perceived Effect was reported to be positive in 16 patients at two years following the procedure. Conclusion Cooled radiofrequency denervation showed long-term efficacy for up to two years in the treatment of sacroiliac joint pain. PMID:23869175

    Full Text Available OBJECTIVE: To evaluate the results of subcostal incisional hernia repair using polypropylene mesh, the technical aspects of musculo-aponeurotic reconstruction, routine fixation of supra-aponeurotic mesh and follow-up for five years.METHODS: We conducted a retrospective study that assessed 24 patients undergoing subcostal incisional hernia repair with use of polypropylene mesh; 15 patients (62.5% were female; ages ranged from 33 to 82, and 79.1% had comorbidities.RESULTS: Early complications: three cases (12.5% of wound infection, three cases (12.5% of seroma, one case (4.1% of hematoma; and one case (4.1% of wound dehiscence. Late complications occurred in one case (4.1% of hernia recurrence attributed to technical failure in the fixation of the mesh and in one case (4.1% of chronic pain. There were no cases of exposure or rejection of the mesh.CONCLUSION: The subcostal incisional hernia, though not very relevant, requires adequate surgical treatment. Its surgical correction involves rebuilding the muscle-aponeurotic defect, supra-aponeurotic fixation of polypropylene mesh, with less complexity and lower rates of complications and recurrences.

    The aim of the study was to evaluate the results of minimally invasive treatment of trochanteric fractures with the use of intramedullary nails. From September 2010 to September 2012 we treated 21 patients with pertrochanteric fractures by a minimally invasive technique using the Gamma 3 (Stryker, Howmedica) nail. There were 13 females and 8 men with a mean age of 74.1 years, ranging from 58 to 88 years. Fractures were classified as being stable (AO type 31-A1) in 5 cases and unstable (AO type 31-A2 and A3) in the rest of 16 cases. Patients were reviewed at 6 weeks and 3 months postoperatively. Mean surgery time was 46.8 minutes and mean hospital stay was 14.9 days. No patients required blood transfusions. During the hospital stay all the patients were mobilized with weight bearing as tolerated. All patients were available for review at 6 weeks, and 2 were lost to the 3 months follow up. 16 patients regained the previous level of activity. This minimally invasive technique using a gamma nail device for pertrochanteric fractures gives reliable good results with excellent preservation of hip function.

    Mucorales are fungi with increasing importance in the clinics. Infections take a rapidly progressive course resulting in high mortality rates. The ergosterol biosynthesis pathway and sterol composition are of interest, since they are targeted by currently applied antifungal drugs. Nevertheless, Mucorales often exhibit resistance to these drugs, resulting in therapeutic failure. Here, sterol patterns of six clinically relevant Mucorales ( Lichtheimia corymbifera , Lichtheimia ramosa , Mucor circinelloides , Rhizomucor pusillus , Rhizopus arrhizus , and Rhizopus microsporus ) were analysed in a targeted metabolomics fashion after derivatization by gas chromatography-mass spectrometry. Additionally, the effect of posaconazole (POS) treatment on the sterol pattern of R. arrhizus was evaluated. Overall, fifteen different sterols were detected with species dependent variations in the total and relative sterol amount. Sterol analysis from R. arrhizus hyphae confronted with sublethal concentrations of posaconazole revealed the accumulation of 14-methylergosta-8,24-diene-3,6-diol, which is a toxic sterol that was previously only detected in yeasts. Sterol content and composition were further compared to the well-characterized pathogenic mold Aspergillus fumigatus . This work contributes to a better understanding of the ergosterol biosynthesis pathway of Mucorales, which is essential to improve antifungal efficacy, the identification of targets for novel drug design, and to investigate the combinatorial effects of drugs targeting this pathway.

    Drug-drug interactions (DDIs) occur when the action of one drug interferes with or alters the activity of another drug taken concomitantly. This can lead to decreased drug efficacy or increased toxicity. Because of DDIs, physicians in the clinical practice attempt to avoid potential interactions when multiple drugs are coadministrated; however, there is still a large knowledge gap in understanding how drugs taken in the past can contribute to DDIs in the future. The goal of this study was to investigate the consequence of neonatal drug exposure on efficacy of other drugs administered up through adult life. We selected a mouse model to test phenobarbital exposure at a neonatal age and its impact on efficacy of omeprazole in adult life. The results of our experiment show an observed decrease in omeprazole's ability to raise gastric pH in adult mice that received single or multiple doses of phenobarbital at a neonatal age. This effect may be associated with the permanent induction of cytochrome P450 enzymes in adult liver after neonatal phenobarbital treatment. Our data indicates that DDIs may result from drugs administered in the past in an animal model and should prompt re-evaluation of how DDIs are viewed and how to avoid long-term DDIs in clinical practice.

    To describe treatment results and identify predictors of the need for surgical intervention in patients with vocal fold pseudocyst. Retrospective cohort study with longitudinal followup via survey. Clinical records were reviewed for demographic information, VHI-10 score, and degree of severity of dysphonia. Videostroboscopic examinations were evaluated for presence of vocal fold pseudocyst, along with additional clinical variables, including laterality, reactive lesion, paresis, varix, and hemorrhage. Follow-up surveys were sent to all participants to evaluate current VHI-10 score and degree of vocal limitation. Results were analyzed to determine predictors of surgery and recurrence of pathology. Forty-six patients (41F:5M) with pseudocyst (40 unilateral: 6 bilateral) were reviewed. Twenty-three (50%) had reactive lesions, nineteen (41%) had paresis by clinical criteria, 10 (22%) had varices, and 6 (13%) had hemorrhage on examination. All underwent initial behavioral management (2-12 sessions of voice therapy; mean of 8 sessions). Seventeen (37%) eventually required surgical intervention. No demographic or clinical variables proved predictive of surgical intervention. Follow-up surveys were completed by 63% of patients, and 79% agreed with the statement that they were not professionally limited by their voices. This experience supports behavioral management as an initial intervention in patients with pseudocyst, sufficient by itself to restore vocal function in approximately two out of three patients. Neither initial severity nor any of the studied clinical findings predicted the need for surgery. The large majority of patients with pseudocyst are able to be treated effectively without impact in their professional function. © 2013 The American Laryngological, Rhinological and Otological Society, Inc.

    This study aimed to evaluate a recently developed equipment test method by assessing the safe and accurate functioning of the Abbott Optium FreeStyle H portable blood glucose monitor for use in the Alfred Hospital's hyperbaric chamber. The results of this study indicate that the test method can be used successfully to evaluate instruments and/or devices for use in the hyperbaric environment. The evaluation initially found that this particular glucose monitor contained a lithium battery which can be hazardous when used in the hyperbaric environment. However, upon further inspection it was determined the battery posed minimal risk for fire and explosion due to its small capacity and design application. The results indicate that the Abbott Optium FreeStyle H blood glucose monitor operated normally when used in the hyperbaric chamber. This glucometer was found to perform within the calibration specification requirements for accuracy at all stages of a typical hyperbaric treatment and as such the Abbott Optium FreeStyle H blood glucose monitor was deemed safe for use in the hyperbaric chamber at the Alfred Hospital.

    Results of 3 year investigation of the influence of the presowing low intensity laser radiation treatment of potato (Solanum tuberosum L.) tubers with the help of laser device with various spectral composition and exposition on plant growth, development and productivity and potato tubers quality and starch content in the conditions of the Republic of Belarus were presented. Presowing tubers treatment of potato cultivars Sante, Yavar and Arkhideya was realized by He-Ne, Ar-, Cu (in course of 3 and 5 minutes) and CO2 (in course of 5 seconds) lasers. Research results have shown that presowing treatment with CO2 laser promoted the higher (on 1,7-6,6%) potato germination capacity in comparison with the control variant without radiation treatment. Height of potato plants of Sante variety after radiation treatment fell behind the control ones. Haulm quantity per one plant and yield quality did not depend on radiation treatment Treatment with CO2 laser exercised the stimulatory action on productivity of Sante variety without changing the starch content in tubers. Tuber weight increased up to 0,4 kg (0,2 kg in the control variant). Similar effect for Arkhideya and Yavar varieties was obtained after Cu-laser treatment in course of 5 minutes. Radiation treatment with He-Ne laser caused the increased starch accumulation (on 0,4-0,6% in comparison with the control variant) in potato tubers of all studied varieties

    Objective We sought to examine rates of eating disorder symptoms among seriously overweight children seeking treatment using the Eating Disorder Examination for Children (ChEDE) and to provide initial data about their association with treatment outcome. Method Overweight children (N = 27) 8–13 years old were interviewed using the ChEDE before participating in a family-based behavioral treatment program. Height and weight were measured pretreatment, posttreatment, and approximately 8 months posttreatment. Results Fifteen percent of children reported subjective bulimic episodes (SBE). Weight loss did not differ for children with and without SBEs, but concerns about body shape were related to larger weight losses during treatment. Conclusion A considerable minority of treatment-seeking overweight children report an episodic sense of loss of control over eating. Loss of control is related to other disordered eating attitudes and behaviors, but does not appear to affect treatment outcome. Future studies are needed to replicate these initial findings.

    Bronchial tuberculosis is a common complication of pulmonary tuberculosis. The present report is to investigate and analyze the indication and efficacy of surgical treatment of bronchial stricture due to severe endobronchial tuberculosis, when the drug and endoscopic treatment were no effect. Reviewed the clinical-pathological records documenting the surgical outcomes in 36 bronchial stricture due to severe endobronchial tuberculosis who underwent lobectomy or pneumonectomy enrolled in our hospital between January 2000 and February 2016. Pneumonectomy in 8 cases, lobectomy in 23 cases, sleeve resection in 5 cases. No intraoperative or early postoperative death occurred. Six patients developed complications. All 6 cases recovered well after treatment. Surgical treatment is still the recommended treatment modatity for bronchial stricture caused by endobronchial tuberculosis due to its good results. It should be performed in time when the drug and intraluninal treatment were no effect for avoiding of being progeressed.

    Background To examine barriers to initiation and continuation of mental health treatment among individuals with common mental disorders. Methods Data are from the WHO World Mental Health (WMH) Surveys. Representative household samples were interviewed face-to-face in 24 countries. Reasons to initiate and continue treatment were examined in a subsample (n= 63,678) and analyzed at different levels of clinical severity. Results Among those with a DSM-IV disorder in the past twelve months, low perceived need was the most common reason for not initiating treatment and more common among moderate and mild than severe cases. Women and younger people with disorders were more likely to recognize a need for treatment. Desire to handle the problem on one’s own was the most common barrier among respondents with a disorder who perceived a need for treatment (63.8%). Attitudinal barriers were much more important than structural barriers both to initiating and continuing treatment. However, attitudinal barriers dominated for mild-moderate cases and structural barriers for severe cases. Perceived ineffectiveness of treatment was the most commonly reported reason for treatment dropout (39.3%) followed by negative experiences with treatment providers (26.9% of respondents with severe disorders). Conclusions Low perceived need and attitudinal barriers are the major barriers to seeking and staying in treatment among individuals with common mental disorders worldwide. Apart from targeting structural barriers, mainly in countries with poor resources, increasing population mental health literacy is an important endeavor worldwide. PMID:23931656

    To assess the prevalence of severe external root resorption and its potential risk factors resulting from orthodontic treatment. A randomly selected sample was used. It comprised conventional periapical radiographs taken in the same radiology center for maxillary and mandibular incisors before and after active orthodontic treatment of 129 patients, males and females, treated by means of the Standard Edgewise technique. Two examiners measured and defined root resorption according to the index proposed by Levander et al. The degree of external apical root resorption was registered defining resorption in four degrees of severity. To assess intra and inter-rater reproducibility, kappa coefficient was used. Chi-square test was used to assess the relationship between the amount of root resorption and patient's sex, dental arch (maxillary or mandibular), treatment with or without extractions, treatment duration, root apex stage (open or closed), root shape, as well as overjet and overbite at treatment onset. Maxillary central incisors had the highest percentage of severe root resorption, followed by maxillary lateral incisors and mandibular lateral incisors. Out of 959 teeth, 28 (2.9%) presented severe root resorption. The following risk factors were observed: anterior maxillary teeth, overjet greater than or equal to 5 mm at treatment onset, treatment with extractions, prolonged therapy, and degree of apex formation at treatment onset. This study showed that care must be taken in orthodontic treatment involving extractions, great retraction of maxillary incisors, prolonged therapy, and/or completely formed apex at orthodontic treatment onset.

    Full Text Available Abstract Study design A prospective treatment study with a new brace was conducted Objective. To evaluate radiological and subjective clinical results after one year conservative brace treatment with pressure onto lordosis at the thoracolumbar joint in children with scoliosis and kyphosis. Summary of background data Conservative brace treatment of adolescent scoliosis is not proven to be effective in terms of lasting correction. Conservative treatment in kyphotic deformities may lead to satisfactory correction. None of the brace or casting techniques is based on sagittal forces only applied at the thoracolumbar spine (TLI= thoracolumbar lordotic intervention. Previously we showed in patients with scoliosis after forced lordosis at the thoracolumbar spine a radiological instantaneous reduction in both coronal curves of double major scoliosis. Methods A consecutive series of 91 children with adolescent scoliosis and kyphosis were treated with a modified symmetric 30 degrees Boston brace to ensure only forced lordosis at the thoracolumbar spine. Scoliosis was defined with a Cobb angle of at least one of the curves [greater than or equal to] 25 degrees and kyphosis with or without a curve Results Before treatment start ‘in brace’ radiographs showed a strong reduction of the Cobb angles in different curves in kyphosis and scoliosis groups (sagittal n = 5 all p Conclusion Conservative treatment using thoracolumbar lordotic intervention in scoliotic and kyphotic deformities in adolescence demonstrates a marked improvement after one year also in clinical and postural criteria. An effect not obtained with current brace techniques.

    Neuromyelitis optica is an inflammatory and usually relapsing demyelinating autoimmune disease of the central nervous system that targets the optic nerves and spinal cord. Rituximab has been used for different neurological diseases that are probably immune-mediated or involving humoural immunity. The objective of this study is to evaluate the efficacy and safety of rituximab as treatment for neuromyelitis optica in a tertiary hospital. Retrospective study of patients with neuromyelitis optica treated with rituximab 1000mg on days 1 and 15, repeated every 6 to 8 months. We recorded EDSS score, relapse rate, overall condition, CD19+ count, presence of anti-NMO antibodies, and possible adverse reactions. Six patients were treated; all were women with a median age of 46 years (range, 38-58). Anti-NMO antibodies were detected in 3 patients (50%). Baseline EDSS was 4 (range 2.0-5.5). Two patients had previously been treated with an immunomodulatory drug. Median time from the first rituximab infusion to first relapse was 3.7 years (range 1.7-6.9). Two patients had infusion reactions after the first dose of rituximab. Four patients remained relapse-free and their EDSS score did not progress during rituximab treatment, one patient showed no clinical improvement, and one patient could not be evaluated. Rituximab can be considered an attractive therapeutic alternative for patients with neuromyelitis optica as there are no approved treatments for this disease. Further studies with rituximab are needed to establish the role of this drug in treating neuromyelitis optica. Copyright © 2013 Sociedad Española de Neurología. Published by Elsevier España, S.L.U.

    Full Text Available Aim: Growing evidence has suggested the utility of short dental implants for oral reconstructive procedures in clinical situations of limited vertical bone height. The aim of this short comunication was to evaluate the clinical use of implants < 10 mm in length and to determine short implant-supported prosthesis success in the atrophic jaw. Materials and methods: Six women and three men were recruited for the treatment of edentulous mandibles. A total of 6 implants were inserted in each patient: two anterior implants of conventional lenght and four posterior 4 mm Titanium Zirconium (TiZr implants. The insertion torque and bone denisty were evaluated. Results: The mean insertion torque for the 4 mm implants was lower than for conventional ones, without any statistical difference. Moreover, most of the patients (88% showed a D2 bone type. Conclusion: The provision of short implant-supported prostheses in patients with atrophic alveolar ridges appears to be a successful treatment option in the short term; however, more scientific evidence is needed for the long term.

Patients rated their pain on a scale from 0 to 10, with higher scores indicating greater pain severity. Results: In total, 425 (post-IHR, 307 (post-TKA, and 501 (posthysterectomy patients were randomized to treatment. There were no statistically significant differences between the pregabalin and placebo groups with respect to the primary endpoint in any of the three trials. The least squares mean difference in worst pain, between 300 mg/d pregabalin and placebo, was -0.7 (95% confidence interval [CI] =-1.4, -0.1; Hochberg adjusted P=0.067 post-IHR; -0.34 (95% CI =-1.07, 0.39; P=0.362 post-TKA; and -0.2 (95% CI =-0.66, 0.31; P=0.471 posthysterectomy. Conclusion: There were no significant differences

    Purpose: Ethmoid sinus cancer is a rare malignancy. Treatment results are mostly reported together with other sinonasal tumors, grouping a wide range of different histologies and treatment approaches. This study reports on the treatment outcome of 47 patients diagnosed with adenocarcinoma of the ethmoid sinuses and treated with surgery and high-dose postoperative radiation therapy. Methods and Materials: Between September 1985 and October 2001, 51 patients with adenocarcinoma of the ethmoid sinuses were referred to the Ghent University Hospital. Four patients were treated with low-dose palliative radiation because of very extended inoperable disease or distant metastasis at the time of diagnosis. They were not included in this analysis. The other 47 patients, all staged as N0M0, were treated with surgery and postoperative high-dose radiation therapy. The median follow-up was 32 months. The T-stages were T1 for 2, T2 for 17, T3 for 11, and T4 for 17 patients. All 47 patients were staged as N0M0. Results: The 3-year, 5-year, and 7-year overall survival are respectively 71%, 60%, and 38%. The 3-year and 5-year disease-free survival are respectively 62% and 36%. The 3-year and 5-year disease-free survival for T1-T2 stages are respectively 87% and 55%, for T3 stages 57% and 28%, and for T4 stages 41% and 25%. The locoregional tumor control was 70% and 59% at respectively 3 and 5 years. Patients presenting with intracranial tumor invasion at the time of diagnosis relapsed within 7 months after the end of radiotherapy. Radiation-induced severe dry eye syndrome and optic neuropathy was observed in respectively 7 and 2 of the 47 cases. Conclusion: Postoperative radiotherapy for adenocarcinoma of the ethmoid sinuses is associated with good local control rates. Crucial for a favorable prognosis is the absence of intracranial invasion. The rarity of these tumors makes it difficult to evaluate new therapeutic advances

    In a case of a driving ability assessment, hair analysis for ethyl glucuronide (EtG) was requested by the authorities. The person concerned denied alcohol consumption and did not present any clinical sign of alcoholism. However, EtG was found in concentrations of up to 910pg/mg in hair from different sampling dates suggesting an excessive drinking behavior. The person declared to use a hair lotion on a regularly base. To evaluate a possible effect of the hair lotion, prospective blood and urine controls as well as hair sampling of scalp and pubic hair were performed. The traditional clinical biomarkers of ethanol consumption, CDT and GGT, were inconspicuous in three blood samples taken. EtG was not detected in all collected urine samples. The hair lotion was transmitted to our laboratory. The ethanol concentration in this lotion was determined with 35g/L. The EtG immunoassay gave a positive result indicating EtG, which could be confirmed by GC-MS/MS-NCI. In a follow-up experiment the lotion was applied to the hair of a volunteer over a period of six weeks. After this treatment, EtG could be measured in the hair at a concentration of 72pg/mg suggesting chronic and excessive alcohol consumption. Overnight incubation of EtG free hair in the lotion yielded an EtG concentration of 140pg/mg. In the present case, the positive EtG hair findings could be interpreted as the result of an EtG containing hair care product. To our knowledge, the existence of such a product has not yet been reported, and it is exceptionally unusual to find EtG in cosmetics. Therefore, external sources for hair contamination should always be taken into account when unusual cosmetic treatment is mentioned. In those cases, it is recommended to analyze the hair product for a possible contamination with EtG. The analysis of body hair can help to reveal problems occurring from cosmetic treatment of head hair. As a consequence, the assessment of drinking behavior should be based on more than one

    Full Text Available Untreated deep dermal burns in children are the cause of long-term treatment and severe cicatricial deformities, resulting in poor cosmetic results and greatly impairing functional outcome. The problem of optimizing the results and timing of treatment of deep burns in children in recent years has become particularly urgent. We observed 1853 children with III-A degree burns. Some of the children's burns healed spontaneously, which led to the development of scar deformities during the first six months after injury. Risk factors for their development, depending on the patient's age and location of the lesion, are pointed out. Other children underwent early tangential excision of eschar. The analysis of the treatment results showed that the use of early surgery in children with deep dermal burns can reduce treatment time, as well as significantly to improve the cosmetic and functional outcomes of trauma.

    Thoria rods irradiated in research reactors were reprocessed for 233 U recovery and resulted in 9 m 3 of acidic Th-bearing raffinate waste. A two step treatment system was planned to treat the raffinate waste. The first step was the generation of thorium lean raffinate waste (TLR) after separation of thorium and the second step was the separation of residual radioactivity and conditioning planned at WIP. The beta activity in the TLR waste is around 50 mCi/i having 137 Cs, 90 Sr and 125 Sb as its main constituents. Shielding calculations were carried out for the various stages of the treatment system at Area-61 of WIP, Trombay. Dose rate evaluations at each step of the treatment system were evaluated to keep the personnel exposure during campaign, ALARA. The work set the base for the shielding design of the treatment system and for the estimation of the man-rem budgeting during commissioning of the system

    This study's main purposes were to: (a) evaluate a treatment manual as a dissemination strategy, (b) compare two workshop formats for evidence-based treatment (EBT) training, and (c) provide preliminary data on therapist characteristics potentially associated with successful EBT adoption. Forty-two community-based clinicians were assigned to one of two training groups (didactic or experiential). Behavior observation and self-report data were collected at four time points. Results suggest that reading a treatment manual is useful, but not sufficient. Experiential and didactic training were equally effective in increasing knowledge, skill, and satisfaction; however, after a 2-day training, few participants demonstrated mastery of skills.

    Treatment results of glioblastoma (GB) during the last 30 years in Tohoku University were analyzed to identify any improvements in patient outcome in all 332 histologically proven cases of newly diagnosed GB treated consecutively in our department between 1982 and 2011. These 30 years was divided into 5 treatment eras, Group 1 (1982-1988, without preoperative evaluation by magnetic resonance [MR] imaging, n=46), Group 2 (1989-1996, with preoperative MR imaging, n=41), Group 3 (1997-1999, additionally underwent intraoperative functional brain mapping and neuronavigation system, n=38), Group 4 (2000-August 2006, underwent 30 Gy of whole brain radiation followed by 30 Gy of extended local accelerated hyperfractionated radiation therapy, n=96), and Group 5 (September 2006-2011, adjuvant usage of temozolomide [TMZ], n=111). Overall survival (OS) was calculated from the date of surgery to the death from any cause. The median survival time/2-year OS/5-year OS of Groups 1 to 5 were 10.7 months/10.9%/0%, 17.3 months/26.2%/6.9%, 15.9 months/23.7%/5.3%, 20.1 months/34.8%/15.5%, and 20.9 months/45.5%/19.7%. The prognosis for patients with GB improved significantly after the introduction of MR imaging. Younger GB, defined as patients aged below 60 years, or total tumor resection with all ages in Group 5 had 5-year OS of 31.0% and 30.1%, respectively. The prognosis of GB was improved significantly after the introduction of TMZ for elderly GB, recursive partitioning analysis class 5, or totally resected GB. Introduction of MR imaging and TMZ, and total resection of the tumor were important in the improvement of outcome for patients with GB. (author)

    Full text: To demonstrate the toxicity and preliminary treatment results of neo-adjuvant regional hyperthermia combined with concurrent radiochemotherapy in oesophageal cancer. Background: In 2002 a phase I study was completed with neo-adjuvant regional hyperthermia combined with chemotherapy (cisplatin and etoposide) in patients with operable oesophageal cancer. It was concluded that hyperthermia was feasible. However, the toxicity of the concurrent chemotherapy was very high, resulting in only 31 % of patients receiving the planned three hyperthermia sessions and 27 % receiving not more than one hyperthermia session. Based on these results we planned to continue hyperthermia in a phase II study aiming at a decrease of (chemotherapy induced) toxicity and an improvement of response rate compared to previous radiochemotherapy studies. In August 2003 a phase II study was started combining five times regional hyperthermia with concurrent radiochemotherapy over a 4,5 weeks period consisting of weekly carboplatin (AUC = 2) and paclitaxel (50 mg/m 2 ) plus 41,4 Gy radiotherapy in 1.8 Gy daily fractions. Chemotherapy was infused during hyperthermia. An oesophagus resection was planned at 4-6 weeks after the end of radiotherapy. 28 patients have entered the study so far, 94 % with a T3 tumor and 59 % with N1 disease on echo-endosonography. Median follow-up is 9 months and 23 patients are evaluable for histological response. Toxicity was much less compared to the previous cisplatin/etoposide study; all five hyperthermia sessions were given in 88 % of patients (and 96 % had at least four sessions). No haematological toxicity was seen and nausea ≤ grade 2 in only 24 %. Dysphagia and weight loss during treatment were absent in 68 % and 81 % of patients respectively. A histological confirmed complete remission rate (CR) was found in 17 % and only residual microscopic tumor foci (Pmic) in an extra 33 %. Partial remission (PR) was accomplished in 33 %.

    In the past, fractures of the mandibular condylar process were, as a rule, treated conservatively. At the Department of Maxillofacial and Oral Surgery of the University Medical Centre Ljubljana, Slovenia, our doctrine was changed in 2002 on the basis of preliminary results and reports in the literature, and these fractures were started to be treated surgically by open reduction and internal fixation with miniplates and screws, which led to good results and a shorter rehabilitation period. The goal of this study was to determine the safety and efficiency of surgical treatment, as well as to compare long-term results of surgical and conservative treatment, as objectively as possible. Two groups of patients, which had all sustained a unilateral, extra-articular mandibular condyle fracture, were compared. In the test group, there were 42 surgically treated patients, and in the control group, 20 conservatively treated patients. Clinical parameters and X-ray images were assessed in both groups and compared by the two tailed Student t test, and in case of attributive variables by the χ(2) test. Within the surgically treated group, postoperative and intraoperative complications were noted: temporary facial nerve palsy, development of a parotid salivary fistula, disturbance of auricle sensibility due to injury of the greater auricular nerve, miniplate fracture, as well as intraoperative bleeding, postoperative haematoma formation, infection, reoperation due to fragment malposition and other complications. Postoperative scars were also assessed. Statistically significant differences between the surgically and conservatively treated patients were found when comparing clinical parameters as well as X-ray images, the results being better in the surgically treated group. Complications of surgical treatment were also noted, the most important among them temporary paresis of facial nerve branches, which occurred in 10 patients (24%). Plate fractures occurred in five patients (12

    Full Text Available Purpose: To evaluate the effect of postoperatively administering a low daily dose of tadalafil on the erectile function of patients who underwent a nerve-sparing radical prostatectomy(NSRP due to localized prostate cancer (PCa. Materials and Methods: Of 138 patients, who underwent NSRP due to PCa between 2012 and 2014, 55 patients who had not had pre-operative erectile dysfunction (ED were included in the study. The mean age of the patients was 64 (54-72. On the 15th day after surgery, after ultrasound evaluation, all 55 patients started on a daily dose of 5 mg tadalafil that was continued for 2.5 months. The erectile function of patients was evaluated pre-operatively, post-operatively, and at the 3rd and 6th month after surgery using the International Index of Erectile Function (IIEF-5 test. None of the patients was treated with hormonal therapy or radiotherapy before or after surgery. Results: Three patients were excluded from the study due to the adverse effects of tadalafil and two patients elected to discontinue the treatment. Of the remaining 50 patients whose pre-operative erectile function had been found normal, at 3 months after surgery, 36 (72% had normal erectile function; of the remaining patients in the study six (12% presented with mild, two (4% with moderate, and six (12% with severe ED. Six months after surgery, 35 patients (70% had normal erectile function while seven (14% had mild, three (6% moderate and five (10% severe ED. There was no statistically significant difference between the results obtained at the 3rd and 6thmonth follow-up (p > 0.05. Three patients reported adverse effects with tadalafil including flushes in 2 (3.6% and a headache in 1 (1.8%. Conclusions: The administration of a 5 mg post-operative dose of tadalafil to patients that had undergone a bilateral NSRP was found to have a positive effect on the recovery and maintenance of erectile function. However, there is still a need to investigate a larger series of

    Full Text Available Introduction. Repetitive transcranial magnetic stimulation (rTMS is a method of brain stimulation which is increasingly used in both clinical practice and research. Up-to-date studies have pointed out a potential antidepressive effect of rTMS, but definitive superiority over placebo has not yet been confirmed. Objective. The aim of the study was to examine the effect of rTMS as an adjuvant treatment with antidepressants during 18 weeks of evaluation starting from the initial application of the protocol. Methods. Four patients with the diagnosis of moderate/severe major depression were included in the study. The protocol involved 2000 stimuli per day (rTMS frequency of 10 Hz, intensity of 120% motor threshold administered over the left dorsolateral prefrontal cortex (DLPFC for 15 days. Subjective and objective depressive symptoms were measured before the initiation of rTMS and repeatedly evaluated at week 3, 6, 12 and 18 from the beginning of the stimulation. Results. After completion of rTMS protocol two patients demonstrated a reduction of depressive symptoms that was sustained throughout the 15-week follow-up period. One patient showed a tendency of remission during the first 12 weeks of the study, but relapsed in week 18. One patient showed no significant symptom reduction at any point of follow-up. Conclusion. Preliminary findings suggest that rTMS has a good tolerability and can be efficient in accelerating the effect of antidepressants, particularly in individuals with shorter duration of depressive episodes and moderate symptom severity.

    Full Text Available Objective: In the present study we investigated the role of hematological parameters, including neutrophil/lymphocyte ratio and platelet/lymphocyte ratio, mean platelet volume and platelet distribution width in the evaluation of treatment efficacy in adult patients diagnosed with cutaneous leishmaniasis. Methods: The study group included 45 adult patients diagnosed with cutaneous leishmaniasis and treated as inpatients in the dermatology clinic between 2011 and 2014. A group of 45 healthy adults served as a control group. Results: Pre- and post-treatment white blood cell count, neutrophils, and lymphocytes were significantly reduced among the patient group relative to the control group. Platelet distribution width, red cell distribution width, neutrophil/lymphocyte ratio and platelet/lymphocyte ratio were significantly elevated among the patients compared to the healthy subjects. Pre-treatment white blood cell, lymphocyte and platelet counts were significantly elevated compared to post-treatment counts among the patient cohort. Treatment was associated with reduced eosinophil count, neutrophil/lymphocyte ratio and platelet/lymphocyte ratio relative to pre-treatment status. Conclusion: Routine hematological testing results such as platelet/lymphocyte ratio, white blood cell count, neutrophil count, red cell distribution width, platelet distribution width, and mean platelet volume may be clinically significant markers of the inflammatory state useful in the evaluation of early treatment efficacy among patients with cutaneous leishmaniasis.

    Objective: To evaluate the clinical value of internal carotid artery occlusion in treatment of intractable epistaxis caused by carotid artery siphon traumatic lesions. Methods: A total of 37 patients with intractable epistaxis caused by traumatic carotid artery siphon pseudoaneurysm or carotid cavernous fistula were retrospectively analyzed. All the patients underwent embolization from October 1998 to June 2010, including 34 men and 3 women with the age ranged from 25 to 65 years and a average of 40 years. Only lesions were occluded in 12 cases without involving the internal carotid artery, while occlusions of internal carotid artery were performed in the rest 25 cases. Results: Thirty-six patients were cured without recurrent hemorrhage after embolization. Only 1 patient with carotid artery occlusion died 48 hours after operation. Conclusion: For patients with carotid arterial intractable epistaxis, if the elimination of the lesions is not applicable and the collateral circulation of Willis ring has a good compensation, the use of detachable balloon or coil occlusion of ipsilateral internal carotid artery is a quick and easy method to save patients' lives.

    In recent years, reports have increased about failure cases caused by high cycle thermal fatigue both at light water reactors and fast breeder reactors. One of the reasons of the cases is a turbulent mixing at a Tee-junction, where hot and cold temperature fluids are mixed, in a coolant system. In order to prevent thermal fatigue failures at Tee-junctions. The Japan Society of Mechanical Engineers published the guideline which is an evaluation method of high cycle thermal fatigue damage at nuclear pipes. In order to justify safety margin and make the procedure of the guideline concise, this paper proposes a new evaluation method of thermal fatigue damage with use of the 'equivalent stress amplitude.' Because this new method makes procedure of evaluation clear and concise, it will contribute to improving the guideline for thermal fatigue evaluation. (author)

    Full Text Available ABSTRACT OBJECTIVE: To evaluate the results of arthroscopic treatment of large and extensive rotator cuff injuries (RCI that involved the supra and infraspinatus muscles using the suture bridge (SB technique. METHODS: Between July 2010 and November 2014, 37 patients with RCI who were treated with SB technique were evaluated. The study included all patients with a minimum follow-up of 12 months who underwent primary surgery of the shoulder. Twenty-four patients were male and 13 were female. The mean age was 60 years (45-75. The dominant side was affected in 32 cases. The most common cause of injury was trauma (18 cases. The mean preoperative motion was 123°, 58°, T11. Through magnetic resonance imaging, 36 fatty degenerations were classified according to Goutallier. Patients underwent rotator cuff repair with SB technique, which consists of using a medial row anchor with two Corkscrew(r fibertape(r or fiberwire(r at the articular margin, associated with lateral fixation without stitch using PushLocks(r or SwiveLocks(r. RESULTS: The mean age was 60 years and mean fatty degeneration was 2.6. The mean range of motion (following the AAOS in the postoperative evaluation was 148° of forward elevation, 55° in lateral rotation and medial rotation in T9. Using the criteria of the University of California at Los Angeles (UCLA, 35 (94% patients had excellent and good results; one (2.7%, fair; and one (2.7%, poor. CONCLUSION: Arthroscopic repair of a large and extensive RCI using SB technique had good and excellent results in 94% of the patients.
