    Purpose: To clarify the immediate effect and long-term results of bronchial artery embolization (BAE) for hemoptysis due to benign diseases and the factors influencing the outcomes.Methods: One hundred and one patients (aged 34-89 years) received bronchial artery embolization with polyvinyl alcohol particles and gelatin sponge for massive or continuing moderate hemoptysis caused by benign pulmonary diseases and resistant to medical treatment.Results: After BAE, bleeding stopped in 94 patients (94%). The immediate effect was unfavorable in cases where feeder vessels were overlooked or the embolization of the intercostal arteries was insufficient. Long-term cumulative hemoptysis non recurrence rates after the initial embolization were 77.7% for 1 year and 62.5% for 5 years. In bronchitis (n 9) and active tuberculosis (n = 4) groups, an excellent (100%) 5-year cumulative non recurrence rate was obtained. The rate was lower in groups with pneumonia/abscess/pyothorax (n = 8) or with pulmonary aspergillosis (n = 9) (53.3%, 1-year cumulative non recurrence). There were higher incidences of early recurrence among patients with massive hemorrhage or more marked vascularity and systemic artery-pulmonary artery shunt in angiography: however, these trends were not statistically significant. Conclusions: BAE can yield long-term benefit in patients with hemoptysis due to benign diseases. Technical problems in the procedure had an impact on the short-term effect. The degree of hemorrhage or the severity of angiographical findings were not significant factors affecting the outcome. The most significant factor affecting long-term results was whether the inflammation caused by the underlying disease was medically well controlled.

    Purpose: To compare the early andlong-term outcomes of subclavian artery angioplasty in patients with aortoarteritis and atherosclerosis. Methods: Sixty-one subclavian artery angioplasties were performed in 55 consecutive patients with aortoarteritis (n= 32) and atherosclerosis (n= 23) between 1986 and 1995. An arch aortogram followed by a selective subclavian artery angiogram was done to profile the site and extent of the lesion, its relation to the vertebral artery, and the distal circulation. Percutaneous transluminal angioplasty (PTA) was performed via the femoral route for 56 stenotic lesions and 5 total occlusions. Results: PTA was successful in 52 (92.8%) stenotic lesions and 3 (60%) total occlusions. Three patients (5.4%) had complications, that could be effectively managed nonsurgically. Compared with atherosclerosis, patients with aortoarteritis were younger (27.4 {+-} 9.3 years vs 54.5 {+-} 10.5 years; p < 0.001), more often female (75% vs 17.4%; p < 0.001), gangrene was uncommon (0% vs 17.4%; p < 0.05), and diffuse involvement was seen more often (43.8% vs 4.4%; p < 0.001). The luminal diameter stenoses were similar before PTA (88.6 {+-} 9.7% vs 89.0 {+-} 9.1%; p= NS). Higher balloon inflation pressure was required to dilate the lesions of aortoarteritis (9.9 {+-} 4.6 ATM vs 5.5 {+-} 1.0 ATM; p < 0.001). This group had more residual stenosis (15.5 {+-} 12.4% vs 8.3 {+-} 9.4%; p < 0.05) after PTA. There were no neurological sequelae, even in PTA of prevertebral lesions. On 3-120 months (mean 43.3 {+-} 28.9 months) follow-up of 40 patients, restenosis was more often observed in patients with aortoarteritis, particularly in those with diffuse arterial narrowing. These lesions could be effectively redilated. Clinical symptoms showed marked improvement after successful angioplasty. Conclusion: Subclavian PTA is safe and can be performed as effectively in aortoarteritis as in atherosclerosis, with good long-term results. Long-term follow-up shows that it

    Purpose To evaluate the outcomes of transconjunctival dacryocystorhinostomy (TRC-DCR) surgery in patients with epiphora due to primary acquired nasolacrimal duct obstruction (PANDO) at second year follow-up. Methods In this retrospective, interventional study, 33 eyes of 29 patients, with epiphora due to PANDO, are included. Lower eyelid conjunctiva is incised at vestibulum inferomedially to access the lacrimal sac and nasal mucosa. Bone is perforated with burr and rongeurs and saccal and nasal flaps are anastomosed. Conjunctival wound edges are apposed and left unsutured. Intraoperative difficulties, surgical time and complications are noted. Average follow-up time was 2 years. Anatomical success was defined as patent lacrimal passages upon irrigation and functional success was defined as relief of epiphora. Results In nineteen (57.6%) eyes the surgeries were completed with the anterior and the posterior flaps sutured. In eight eyes (24.2%) only anterior flaps could be sutured. In 6 eyes (18.2%), the surgical procedure was converted to external dacryocystorhinostomy since the nasal mucosa could not be exposed adequately via transconjunctival route. The mean surgical time was 65.1 min. One patient had a millimeter long lower eyelid margin laceration in one eye (3.7%) intraoperatively due to traction for visualization of the operative site. Epiphora resolved in 25 of 27 eyes (92.5%) in whom TRC-DCR could be completed. Epiphora and failure to irrigation were noted in two eyes (7.4%) at the postoperative 4th and 8th months, respectively and required reoperation. No complications occurred, except granuloma formation at the conjunctival incision site in three eyes (11.1%). Epiphora resolved in all the six eyes of patients who underwent an external DCR (100%). Conclusion Transconjunctival dacryocystorhinostomy is a scarless dacryocystorhinostomy technique which is performed without endoscope and/or laser assistance, with 92.5% success rate comparable to external DCR at

    The present study aimed to investigate the clinical outcomes of autologous cultivated oral mucosal epithelial transplantation (COMET) on human amniotic membrane (AM) for corneal limbal stem cell deficiency (LSCD). In this prospective, noncomparative case series, 20 eyes (18 patients) with bilateral severe ocular surface disease were chosen to undergo COMET on human AM. The primary outcome was clinical success, and the secondary outcomes were the best-corrected visual acuity difference, corneal opacification, symblepharon formation, and complications. The mean patient age was 48.2 ± 15.5 years. The mean follow-up time was 31.9 ± 12.1 months (range 8-50 months). All except one eye exhibited complete epithelialization within the first postoperative week. A successful clinical outcome, defined as a stable ocular surface without epithelial defects, a clear cornea without fibrovascular tissue invasion at the pupillary area, and no or mild ocular surface inflammation, was obtained in 15 of 20 eyes (75 %). The clinical success rate at 1 year was 79.3 %, and that at 4 years (end of follow-up) was 70.5 %. Fourteen of 20 (70 %) eyes exhibited improvement in visual acuity after COMET, and some required subsequent cataract surgery (2 eyes), penetrating keratoplasty (3 eyes), or keratoprosthesis implantation (1 eye). Preoperative symblepharon was eliminated in most eyes (8 of 13, 61.5 %) after COMET combined with eyelid reconstruction when needed. The only complication was corneal perforation (1 eye) induced by a severe eyelid abnormality; treatment with a tectonic corneal graft was successful. COMET can successfully restore ocular surface damage in most eyes with corneal LSCD. PMID:27507558

    Purpose Several alternative procedures have been proposed to achieve complete revascularization in the presence of diffuse left anterior descending coronary artery (LAD) disease. With the extensive use of internal thoracic artery grafts in coronary artery bypass procedures, sequential anastomosis of the left internal thoracic artery (LITA) to LAD has gained popularity in these challenging cases. The long term results of sequential LITA to LAD anstomosis were examined in this study. Patients and Methods In order to determine the long term results of the sequential revascularization of LAD by LITA graft, 41 out of 49 patients operated between January 2001 and December 2005 were selected for control coronary arteriography. The median period for control coronary arteriography was 64 months. Results Seventy five anastomoses were found to be fully patent (91,46%) among the 82 sequential LITA anastomoses (41 LITA grafts) on the LAD at a median follow-up period of 64 months (53 to 123 months). Among the 41 LITA grafts used for this purpose, 36 were found intact (complete patency of the proximal and distal anastomoses) (87,8%). Two LITA grafts (4 anastomoses) were found to be totally occluded (4,87%). The proximal anastomosis of the LITA graft was observed to be 90% stenotic in one patient (1,21%). In one patient tight stenosis of the distal anastomosis line was observed (1,21%), while in another patient 70% narrowing of LITA lumen after the proximal anastomosis was detected (1,21%). Conclusion We strongly beleive that sequential LITA grafting of LAD is a safe alternative in the presence of severe LAD disease to achieve complete revascularization of the anterior myocardium with patency rates not much differing from conventional single LITA to LAD anastomosis.

    Purpose To investigate the clinical outcomes of endovascular therapy (EVT) in octogenarians and nonoctogenarians with peripheral arterial disease. Methods A retrospective analysis of 511 patients (654 affected legs) who underwent EVT between July 2005 and December 2013 was conducted in a prospectively maintained database. Immediate results and long-term vascular outcomes were analyzed and compared between octogenarians and nonoctogenarians. Results Octogenarians were more likely to be female and have atrial fibrillation (AF), whereas nonoctogenarians had higher rates of obesity, claudication, and medical comorbidities. There were no differences in the rates of EVT success, 30-day major adverse vascular events, and 6-month functional improvement between groups. Over the 10-year follow-up period, the rates of 3-year limb salvage, sustained clinical success, freedom from major cerebrovascular and cardiovascular events, and composite vascular events were similar between groups, but the survival rate was better in nonoctogenarians than in octogenarians (73% vs 63%, respectively, P=0.004). In Cox regression analysis, dependence on dialysis and AF were significant predictors of death (odds ratio [OR] 4.44 in dialyzed and 2.83 in AF patients), major cerebrovascular and cardiovascular events (OR 3.49 and 2.45), and composite vascular events (OR 3.14 and 2.25). Conclusion EVT in octogenarians was feasible, without an increased risk of periprocedural complications. The rates of limb salvage, sustained clinical success, and long-term vascular events were comparable between groups. Dialysis dependence and AF are independent predictors for poor prognosis in patients with peripheral arterial disease. However, these observations require further confirmation in larger scale studies. PMID:27217735

    Venous stenting has been shown to effectively treat iliofemoral venous obstruction with good short- and mid-term results. The aim of this study was to investigate long-term clinical outcome and stent patency. Twenty patients were treated with venous stenting for benign disease at our institution between 1987 and 2005. Fifteen of 20 patients (15 female, mean age at time of stent implantation 38 years [range 18-66]) returned for a clinical visit, a plain X-ray of the stent, and a Duplex ultrasound. Four patients were lost to follow-up, and one patient died 277 months after stent placement although a good clinical result was documented 267 months after stent placement. Mean follow-up after stent placement was 167.8 months (13.9 years) (range 71 (6 years) to 267 months [22 years]). No patient needed an additional venous intervention after stent implantation. No significant difference between the circumference of the thigh on the stented side (mean 55.1 cm [range 47.0-70.0]) compared with the contralateral thigh (mean 54.9 cm [range 47.0-70.0]) (p = 0.684) was seen. There was a nonsignificant trend toward higher flow velocities within the stent (mean 30.8 cm/s [range 10.0-48.0]) and the corresponding vein segment on the contralateral side (mean 25.2 cm/s [range 12.0-47.0]) (p = 0.065). Stent integrity was confirmed in 14 of 15 cases. Only one stent showed a fracture, as documented on x-ray, without any impairment of flow. Venous stenting using Wallstents showed excellent long-term clinical outcome and primary patency rate.

    ABSTRACT Aim: To evaluate the long term outcomes of temporary urethral stent placement for the treatment of recurrent bulbar urethral stricture. Materials and Methods: Twenty-eight patients who underwent temporary polymer coated urethral stent placement due to recurrent bulbar urethral stricture between 2010 and 2014 were enrolled in the study. The long term outcomes of the patients were analyzed. Results: The mean age of the patients was 62.3±6.4 (44–81). The overall clinical success was achieved in 18 (64.2%) of the 28 patients at a median (range) follow-up of 29 (7–46) months. No patient reported discomfort at the stent site. Stone formation was observed at the urethral stent implantation area only in one patient. Stenosis occurred in the distal end of the stents in two patients and took place in bulbar urethra in seven patients after removed the stents. The mean maximum urine flow rates were 6.24±2.81mL/sec and 19.12±4.31mL/sec before and at 3 months after the procedure, respectively. Conclusion: In this study, the success rate of temporary urethral stent placement has remained at 64.2% at a median follow-up of 29 months. Therefore, our outcomes have not achieved desired success rate for the standard treatment of recurrent bulbar urethral stricture. PMID:27256191

    Blood transfusion and iron chelation currently represent a supportive therapy to manage anemia, vasculopathy and vaso-occlusion crises in Sickle-Cell-Disease. Here we describe the first 5-year long-term randomized clinical trial comparing Deferiprone versus Deferoxamine in patients with Sickle-Cell-Disease. The results of this study show that Deferiprone has the same effectiveness as Deferoxamine in decreasing body iron burden, measured as repeated measurements of serum ferritin concentrations on the same patient over 5-years and analyzed according to the linear mixed-effects model (LMM) (p=0.822). Both chelators are able to decrease, significantly, serum ferritin concentrations, during 5-years, without any effect on safety (p=0.005). Moreover, although the basal serum ferritin levels were higher in transfused compared with non-transfused group (p=0.031), the changes over time in serum ferritin levels were not statistically significantly different between transfused and non-transfused cohort of patients (p=0.389). Kaplan-Meier curve, during 5-years of study, suggests that Deferiprone does not alter survival in comparison with Deferoxamine (p=0.38). In conclusion, long-term iron chelation therapy with Deferiprone was associated with efficacy and safety similar to that of Deferoxamine. Therefore, in patients with Sickle-Cell-Disease, Deferiprone may represent an effective long-term treatment option. PMID:24814618

    Takayasu arteritis is a chronic inflammatory arteriopathy of unknown etiology affecting the aorta and proximal portion of its main branches. Although it was initially reported in young women of Oriental descent, its current worldwide distribution is known to affect both sexes. In the last decade, percutaneous transluminal angioplasty (PTA) has emerged as a viable alternative in its treatment. However, the percentage of restenosis is more common in Takayasu disease than atherosclerotic lesions (21% vs 10%), probably due to diffuse inflammatory vascular involvement. Since the introduction of stent, this technique has emerged as a viable alternative to treatment of atherosclerotic stenotic lesions, although its efficacy and safety in Takayasu disease is still unclear. Herein, we report our experience in a woman with subclavian steal syndrome in whom Takayasu disease was diagnosed and treated with subclavian artery angioplasty and stent, with a good outcome during four years of follow-up.

    Noma, also known as cancrum oris, is an infectious disease that results in a loss of orofacial tissue, due to gangrene of soft and bony tissue. It is especially seen in young children in the sub-Saharan region. Among the sequelae of patients who survive noma, trismus is one of the most disabling. This retrospective research studied the long-term results of trismus release in noma patients. Thirty-six patients could be traced in the villages and were included in the study. The mean mouth opening in this group was 10.3mm (95% CI: 7.0; 13.6mm) and the mean period after discharge from hospital was 43 months. Better mouth opening was observed in patients who continued physiotherapy after discharge, were older, and those with a 'soft' (vs. 'hard') inner and outer cheek on palpation. The result of trismus release in noma patients in the long term was extremely poor in this study.

    Arthrocentesis is a simple procedure, that may be performed under local anaesthesia and entails low risks of complications. It consists in the lavage of the upper joint compartment of the temporo-mandibular articulation through two transcutaneous needles of entrance and exit. The simplicity of execution, the low costs of the material employed and the excellent results published cause that this technique is beginning to be included in international protocols of treatment of temporomandibular dysfunctions. The clinical study involves 26 articulation in 25 patients. The age of the subjects at the time of the treatment ranged from 16 to 70 years. The follow-up of the patients treated ranges from a minimum of 12 to a maximum of 53 months. The most significant parameters to assess the effectiveness of the articular lavage, performed by the arthrocentesis technique, are the local pain intensity and the millimetre analytic comparison of the mouth opening and the mandibular movements in protrusion and laterality. A Student's "t" test was used to compare pre-treatment and post-treatment differences in level of TMJ pain and maximal mouth opening, in both cases section valve was less then 0.05 and so statistically significant.

    In this paper, we have shown that long-term treatment of NZB mice with anti-CD4 antibody results in four major pathological effects: firstly the development of a severe wasting disease; secondly lymphoid atrophy of the thymus, spleen, mesenteric lymph node and Peyers patches (PP); thirdly, severe chronic ulcerative colitis and fourthly a neutrophilia with neutrophil infiltration in the spleen, liver and mesenteric lymph nodes. At the same time, mice subjected to anti-CD4 treatment showed a reduction in the microbial diversity in ileal walls and contents, as well as in colonic contents, together with overgrowth of E. coli in the intestinal lumen and wall. In addition, there was the appearance of large numbers of spiral shaped bacteria on the mucosal surface often associated with colonic ulceration. PMID:21327045

    Aim of this study is to assess the efficacy, safety, and long-term results of doppler-guided hemorrhoidal artery ligation procedure with a 7-year follow-up period for treatment of grade II and III degree hemorrhoidal diseases. The procedure was performed by a specially designed proctoscope to locate and ligate all terminal branches of superior rectal artery. Patients were followed up at postoperative 1st week and 3rd, 12th, and 24th months by physical examination and 7th year by phone questionnaire using Short Form-36. Between November 2006 and May 2007, 50 patients (29 females, mean age = 38.2) underwent this procedure. All patients discharged at operation day and mean return to work was 2.5 days. There were no major complications and mean postoperative Visual Analogous Scale at first week was 1.72. At 24th month, 44 (88%) and 38 (76%) patients at 7th year were symptom free. Doppler-guided hemorrhoidal artery ligation is a safe, effective, and outpatient procedure, which can be the treatment of choice for second- and third-degree hemorrhoidal diseases with satisfactory long-term results.

    Background Anterior interbody fusion of the cervical spine have become the gold standard for treating spinal diseases, hence the aim of this study was to compare long term follow up results in patients with cervical disk disease treated with anterior PEEK cage implantation and without it in anterior approach. Methods Retrospectively 63 patients with known cervical discogenic disorders who went under surgery with and without cage implantation were enrolled. The neurological examination and neurologic function were assessed by using the Japanese Orthopedic Association (JOA) scoring system and neurological cervical spine scale (NCSS) before and 8 years after surgery in each patient and at the end all complications were recorded. Results In the first group, there were 15 males and 14 females (mean age: 49±10 years) and in the second group there were 27 male and 7 female (mean age: 47±9 years). The NCSS score was significantly different between two groups after surgery (p = 0.035) but there was no significant difference before surgery (p = 0.163). No statistical significance difference was also observed in JOA score and complications before and after procedure, but JOA post surgery score between two groups had significant difference (p = 0.047). Conclusion In conclusion, present study showed that PEEK cage implantation is a highly useful alternative to the conventional treatment methods. PMID:23482426

    Objective Patients with inflammatory joint diseases (IJD) have a high prevalence of hypertension and increased arterial stiffness. The aim of the present study was to evaluate the effect of long-term rosuvastatin treatment on arterial stiffness, measured by augmentation index (AIx) and aortic pulse wave velocity (aPWV), and blood pressure (BP) in IJD patients with established atherosclerosis. Methods Eighty-nine statin naïve IJD patients with carotid atherosclerotic plaque(s) (rheumatoid arthritis n = 55, ankylosing spondylitis n = 23, psoriatic arthritis n = 11) received rosuvastatin for 18 months to achieve low-density lipoprotein cholesterol goal ≤1.8 mmol/L. Change in AIx (ΔAIx), aPWV (ΔaPWV), systolic BP (ΔsBP) and diastolic BP (ΔdBP) from baseline to study end was assessed by paired samples t-tests. Linear regression was applied to evaluate associations between cardiovascular disease (CVD) risk factors, rheumatic disease specific variables and medication, and ΔAIx, ΔaPWV, ΔsBP and ΔdBP. Results AIx, aPWV, sBP and dBP were significantly reduced from baseline to study end. The mean (95%CI) changes were: ΔAIx: -0.34 (-0.03, -0.65)% (p = 0.03), ΔaPWV: -1.69 (-0.21, -3.17)m/s2 (p = 0.03), ΔsBP: -5.27 (-1.61, -8.93)mmHg (p = 0.004) and ΔdBP -2.93 (-0.86, -5.00)mmHg (p = 0.01). In linear regression models, ∆aPWV was significantly correlated with ΔsBP and ΔdBP (for all: p<0.001). Conclusions There is an unmet need of studies evaluating CVD prevention in IJD patients. We have shown for the first time that long-term intensive lipid lowering with rosuvastatin improved arterial stiffness and induced a clinically significant BP reduction in patients with IJD. These improvements were linearly correlated and may represent novel insight into the pleiotropic effects by statins. Trial Registration ClinicalTrials.gov NCT01389388 PMID:27093159

    In a longitudinal cohort (prevention group, n=213, comparison group, n=163) of 10-year prospective follow-up we addressed efficacy of 5-year-long multifactor preventive intervention, conducted in a sample of population of 12 year old boys. Preventive intervention was carried out both at populational level and among persons with risk factors of development of cardiovascular diseases with the use of group, individual, and partly family approaches, and was directed at rationalization of nutrition, elevation of physical activity and prevention of harmful habits. During first 3 years of prevention we succeeded to achieve stable statistically significant lowering of mean levels of total cholesterol, low density lipoprotein cholesterol, triglycerides, and atherogeneity index, as well as to affect fatty component of body mass (skinfold thickness). Long term effect of 5-year long preventive intervention manifested as significantly lower level of systolic blood pressure, lower prevalence of low levels of high density lipoprotein cholesterol, smaller increment of low density lipoprotein cholesterol and index of atherogeneity in the prevention group. These results evidence that prevention of main factors of risk of development of cardiovascular diseases (obesity, arterial hypertension, disorders of lipid composition of the blood, and low physical activity) in child and adolescent age in the period of active growth and development is feasible, effective, safe and is able to lead to decrease of levels of these factors in adults, but should last uninterruptedly until formation of stable habits of healthy life style.

    Purpose: To analyze long-term outcome and prognostic factors for high-risk prostate cancer defined by National Comprehensive Cancer Network criteria treated with high-dose radiotherapy and androgen deprivation in a single institution. Methods and Materials: A total of 306 patients treated between 1995 and 2007 in a radiation dose-escalation program fulfilled the National Comprehensive Cancer Network high-risk criteria. Median International Commission on Radiation Units and Measurements radiation dose was 78 Gy (range, 66.0-84.1 Gy). Long-term androgen deprivation (LTAD) was administered in 231 patients, short-term androgen deprivation (STAD) in 59 patients, and no hormones in 16 patients. The Phoenix (nadir plus 2 ng/mL) consensus definition was used for biochemical control. Multivariate analysis was performed to determine the independent prognostic impact of clinical and treatment factors. Median follow-up time was 64 months (range, 24-171 months). Results: The actuarial overall survival at 5 and 10 years was 95.7% and 89.8%, respectively, and the corresponding biochemical disease-free survival (bDFS) was 89.5% and 67.2%, respectively. Fourteen patients (4.6%) developed distant metastasis. Multivariate analysis showed that Gleason score >7 (p = 0.001), pretreatment prostate-specific antigen (PSA) level >20 ng/mL (p = 0.037), higher radiation dose (p = 0.005), and the use of adjuvant LTAD vs. STAD (p = 0.011) were independent prognostic factors affecting bDFS in high-risk disease. The 5-year bDFS for patients treated with LTAD plus radiotherapy dose >78 Gy was 97%. Conclusions: For high-risk patients the present series showed that the use of LTAD in conjunction with higher doses (>78 Gy) of radiotherapy was associated with improved biochemical tumor control. We observed that the presence of Gleason sum >7 and pretreatment PSA level >20 ng/mL in the same patient represents a 6.8 times higher risk of PSA failure. These men could be considered for clinical trials with

    Purpose. To retrospectively evaluate the 10 year follow-up results in patients who had 'kissing' self-expanding stent aortic bifurcation reconstruction. Methods. Forty-three patients were treated with 'kissing' self-expanding stents for aortoiliac occlusive disease. Early follow-up with clinical and ankle brachial pressure indices (ABPI) was performed at 3, 6, 12, and 24 months and with intra-arterial digital subtraction angiography at 12-24 months; clinical and angiographic follow-up was performed for symptom recurrence up to 10 years after treatment. Retrospective record review was performed to assess mortality, clinical patency, angiographic patency, and secondary assisted patency of both stents and downstream peripheral vessels at 5 and 10 years follow-up. Results. The 2 year primary angiographic and secondary assisted stent patencies were 89% and 93%, respectively. At 10 years follow-up in 40 patients the mortality was 38% (due to myocardial infarction, stroke, chronic renal failure, malignancy, and liver failure). At 5 and 10 years follow-up the primary clinical stent patency was 82% and 68%, and the secondary assisted stent patency 93% and 86%, respectively. At 5 and 10 years, the distal vessel patency was 86% and 72%, and the secondary assisted distal vessel patency treated by surgical or endovascular techniques was 94% and 88%, respectively. At 10 years there was no limb loss. Conclusion. The long-term (10 year) results of aortic bifurcation arterial self-expanding stent placement in patients with arterial occlusive disease show a 10 year primary stent patency rate of 68% but a secondary assisted patency rate of 86%. In addition there is a high overall mortality due to other cardiovascular causes and the rate of distal disease progression and loss of patency is similar to the loss of stent patency rate.

    The main application of endoscopic surgery relies on the middle ear cholesteatoma surgical treatment, although for a definitive validation and acceptance by scientific community, long-term results are needed about recurrent and residual rates of the pathology. The aim of the present paper was to analyze the single institution experience with the long-term results of surgical treatment of attic cholesteatoma. PMID:27565391

    In chronic rheumatic diseases, recent treatment regimens comprise multimodal concepts including pharmacologic, physical/exercise, occupational and psychological therapies. Rehabilitation programmes are used for long-term management of disease. Spa therapy is often integrated in various middle and south European and Asian countries. Here, we investigated radon spa therapy as applied in health resorts compared to a control intervention in rheumatic out-patients. Randomised, blinded trial enroling 681 patients [mean age 58.3 (standard deviation 11.1); female 59.7%] in 7 health resorts in Germany and Austria with chronic back pain (n 1 = 437), osteoarthritis (OA) (n 2 = 230), rheumatoid arthritis (n 3 = 98), and/or ankylosing spondylitis (n 4 = 39); multiple nominations in 146 cases). Outcomes were pain (primary), quality of life, functional capacity, and medication measured before start, after end of treatment, and 3 times thereafter in 3 monthly intervals. Adverse events were documented. To analyse between-group differences, repeated-measures analysis of covariance was performed in metric endpoints and Fisher's exact test in rates. Two-sided significance level of 5% was chosen. Until end of follow-up, superiority of radon therapy was found regarding pain relief (p = 0.032) and analgesic drug consumption (p = 0.007), but not regarding quality of life. Functional capacity was assessed specific to the underlying indication. Significant benefits were found in radon-treated OA patients until 6-month follow-up (p = 0.05), but not until end of study (p = 0.096). Neither the back pain sub-population nor the two smaller patient populations with inflammatory indications benefited significantly in functional capacity. Results suggest beneficial analgesic effects of radon spa therapy in rheumatic diseases until 9 months post-intervention.

    The purpose of this study was to evaluate histologically the long-term response to intentional tooth reimplantation in six rhesus monkeys. The study revealed that cervical and apical root resorption is a universal complication after tooth reimplantation and that arrested areas of resorption will show repair by deposition of cementum. A highly cellular periodontal membrane usually will develop. Periodontal fibers will reattach to reparative bone and cementum but seldom regain functional orientation. Partial or complete ankylosis may result. A further complication is progressive undermining resorption of the ankylosed teeth. Long-term studies are mandatory to evaluate the response to intentional tooth reimplantation.

    Eight patients with Kawasaki disease who had sustained asymptomatic myocardial infarction 8-15 years ago (mean, 13.1 years) were reexamined by various noninvasive cardiac function tests to assess long-term prognosis. At present, electrocardiograms (ECGs) are normal in six patients. However, all eight patients had a prolonged preejection period (PEP) to left ventricular ejection time (LVET) ratio 30 s after amylnitrate (AN) inhalation. Six patients had perfusion defects by exercise thallium-201 myocardial scintigraphy, and two patients developed ST segment depression in treadmill exercise testing. These patients are symptom-free even though their physical activity has not been restricted. Yet they proved to have serious abnormalities suggesting sequelae of myocardial infarction or existing myocardial ischemia. Judging from the results of noninvasive cardiac function tests and recently performed coronary angiography, five of the eight patients require coronary bypass surgery.

    AIM: To determine the long-term results of choledochodudenostomy in patients with benign billiary obstruction. METHODS: This prospective study was conducted at Sheri Kashmir Institute of Medical Sciences Srinagar Kashmir, India over a period of 10 years from January 1997 to December 2007. The total number of patients who underwent choledochoduodenostomy during this period was 270. On the basis of etiology of biliary tract obstruction, patients were divided into a calculus group, an oriental cholangiohepatitis group, a benign biliary stricture group and others. Patients were followed for a variable period of 13 mo to 15 years. RESULTS: Choledochoduodenostomy (CDD) with duo-denotomy was performend in four patients. CDD with removal of T- tube, CDD with left hepatic lobectomy and CDD with removal of intra biliary ruptured hydatid was performed in three patients each. In the remaining patients only CDD was performed. Immediate post operative complications were seen in 63 (23%) patients, while long-term complications were seen in 28 (11%) patients, which were statistically significant. Three patients died during hospitalization while four patients died in the late post-operative period. CONCLUSION: Our conclusion is that CDD is safe and produces good long term results when a permanent biliary drainage procedure is required. PMID:22408717

    The authors' objective was to evaluate the effectiveness of radical surgery with lymph node dissection for gallbladder carcinoma. Long-term results were analyzed in 40 patients in a 5-year study. The authors divided the 40 cases into two groups: 20 without positive nodes and 20 with positive nodes. In the group without positive nodes, one patient who underwent R1 resection died of a recurrence at 1 year 7 months. Seventeen of the 19 patients treated with R0 resection survived more than 5 years. The 5-year survival rate was 85% (17/20). In the group with positive nodes, 9 of the 13 patients treated with R0 resection survived more than 5 years, whereas the seven patients treated with R1 or R2 resection died within 5 years. The 5-year survival rate was 45% (9/20). Patients treated by R0 resection showed a 5-year survival rate of 69% (9/13). Thus we documented the favorable long-term results of radical surgery. R0 resection is a prerequisite for long-term survival. The results justify radical surgery with lymph node dissection. PMID:1359844

    OBJECTIVE—The purpose of this study was to compare the long term effectiveness between chloroquine (CQ) and hydroxychloroquine (HCQ).
METHODS—Medical charts of all patients seen by eight rheumatologists practising in two tertiary care centres and starting antimalarial treatment between January 1985 and December 1993 were reviewed. Patient characteristics, disease, and treatment information were collected. The main outcome measures were the cause of and the time to the discontinuation of antimalarial drugs resulting from all causes, principally toxicity or inefficacy, or both. Bivariate analysis including t tests and χ2 tests were used to assess differences between means and proportions respectively. Survival curves were evaluated using the Kaplan-Meier method. Multivariate analysis (Cox regression) was used to adjust for potential confounders.
RESULTS—After all medical records were reviewed, 1042 eligible cases were identified. From these, 940 (90%) had usable information and they represent the cohort. Five hundred and fifty eight had rheumatoid arthritis, 178 had systemic lupus erythematosus, 127 had palindromic arthritis, and 77 had other diagnoses. Fifty seven per cent of the patients received CQ and 43% HCQ. The proportion of patients with side effects taking HCQ and CQ was 15% and 28% respectively (p=0.001). Using Cox regression model to adjust for age at the onset of antimalarial treatment, physician differences, sex, disease type, disease duration before treatment, and rank selection, there were no differences in the hazard ratio (HR) for overall discontinuations between CQ and HCQ. While the HR for discontinuations because of toxicity was lower for HCQ (HR= 0.6, 95% CI 0.4, 0.9), the HR for discontinuations because of inefficacy was significantly higher for HCQ (HR= 1.4, 95% CI 1.1, 1.9).
CONCLUSIONS—After adjusting for time and several confounders HCQ was less toxic but less effective than CQ. Only one case of probable

    Objectives: Talar neck and body fractures are unusual fractures. The purpose of this study is to determine the prevalence of long term results. Material and Methods: A retrospective analysis was carried out including 11 patients that underwent surgical treatment for body or neck talus fractures between January 1997 and December 2005. Final follow-up examination included a clinical evaluation (AOFAS score) and standard radiographs. Results: The mean follow-up time was 58.5 months. The prevalence of associated fractures was 60% (6/10). Overall AOFAS score averaged 72 [19-100]. Avascular necrosis and post-traumatic arthritis were present in half of the patients. Quality of surgical reduction, body fractures and absence of degenerative changes were correlated with better functional results. Neck fractures, osteonecrosis and posttraumatic arthritis led to inferior results. Conclusion: There is a great potential for long term functional impairment due to posttraumatic arthritis and chronic pain in this kind of fracture. Anatomic surgical reduction is the best chance to avoid them but it is not infallible. The avascular necrosis rate correlates with initial fracture displacement, but its occurrence in each specific case is unpredictable. PMID:27004192

    The Wagner cone prosthesis is indicated in uncemented total hip replacement of cases with cylinder-shaped femurs, deformed femurs, femurs with increased antetorsion, and in conditions of intramedullary bony scar tissue after previous osteotomies. The objective of this study is to present long-term results. From January 1, 1993 to December 31, 1995, 132 implantations were made with the Wagner cone prosthesis. We report the clinical and radiographic results of 94 cone prostheses with a mean observation period of 11.5 years. The Merle d’Aubigné score improved from a preoperative mean value of 8.8 to a postoperative mean of 16.3. The radiographic evaluation revealed 32 cases with cortical hypertrophy, 73 cases with atrophy of the proximal femur, and 18 cases with complete pedestal formation. Radiolucencies over Gruen zones 1 and 7 occurred in 42 cases; only zone 1 was affected in 24 cases. Complications included three deep infections, three acetabular revisions, five total joint revisions, one recurrent luxation, and three heterotopic ossifications. In spite of the fact that the examined cohort often included patients who had undergone multiple previous operations (a maximum of six) of the proximal femur or the acetabulum, the long-term results of the Wagner cone prostheses were very promising.

    We evaluated the long-term results of recanalization with primary stenting for patients with long and complex iliac artery occlusions. This was a retrospective nonrandomised study. Between 1995 and 1999, 138 patients underwent recanalization of an occluded iliac artery with subsequent stenting. Patency results were calculated using Kaplan-Meier analysis. The mean length of follow-up was 108 months. Variables affecting primary stent patency such as patient age; stent type and diameter; lesion site, shape, and length; Society of Cardiovascular and Interventional Radiology classification; total runoff score; Fontaine classification; and cardiovascular risk factors were analysed using Breslow test. These variables were then evaluated for their relation to stent patency using Cox proportional hazards test. Technical success was 99%. Primary patency rates were 90% (SE .024), 85% (SE .029), 80% (SE .034), and 68% (SE .052) at 3, 5, 7, and 10 years, respectively. Lesion site (p = 0.022) and stent diameter (p = 0.028) were shown to have a statistically significant influence on primary stent patency. Long-term results of iliac recanalization and stent placement were excellent, without major complications, even in highly complex vascular obstructions. A primary endovascular approach appears to be justified in the majority of patients as a less invasive alternative treatment to surgery. In any case, a first-line interventional approach should be considered in elderly patients or in patients with severe comorbidities.

    The first 128 consecutive patients with uveal melanomas treated with proton beam irradiation were studied in order to evaluate survival and visual acuity status of patients with relatively long-term follow-up. The median follow-up was 5.4 years, and no patient was lost to follow-up. All tumors showed regression. The most recent visual acuity was 20/40 or better in 35% and 20/100 or better in 58%. Eight eyes were enucleated because of complications. Metastasis developed in 26 patients (20.5%) from 3 months to 7 years after treatment. Results indicate that proton irradiation is quite successful for achieving local control of uveal melanomas. A large proportion of the treated eyes maintained useful vision. Five-year follow-up data indicate that proton irradiation has no deleterious effect on the likelihood of the development of metastasis.

    The key to management of alcoholic liver disease (ALD) is early recognition by the patient and physician. Excessive alcohol consumption, ranging from drinking more than recommended amounts to abuse, is one of the most preventable causes of death and disability. The US Preventive Services Task Force guidelines recommend screening for alcoholism in the primary care setting. Abstinence is the cornerstone of therapy and it decreases mortality and morbidity significantly. Alcoholic cirrhosis can cause varices that need to be followed closely with upper endoscopy to prevent or treat hemorrhage. In this review, we describe an approach to long-term management of ALD.

    The aim of our study was to assess long-term results of radiofrequency volumetric tissue reduction of inferior turbinates (RVTR). We performed a prospective long-term longitudinal evaluation of 305 patients affected by rhinitis (114 allergic and 191 non-allergic) who were unresponsive to medical treatment and underwent RVTR (January 2004 - December 2010). Subjects were followed for a mean period of 39.70 ± 19.41 months (range 24-60). Patients completed the NOSE-scale questionnaire pre- and post-operatively after 1 month and yearly for 5-years. Recurrence was assumed if the post-operative total NOSE score increased by at least 75% during follow-up and the patient restarted medical treatments. Estimation of relapse over time was performed by Kaplan-Meyer analyses. We documented overall good satisfaction of patients regarding the procedure, with a good rate of pain control and a low rate of complications. Post-operatively there was a significant improvement in nasal stuffiness, nasal obstruction and mouth breathing (p < 0.05). We observed a worsening trend for symptoms after 36 months with progressive increasing rate of recurrences that were significantly higher in allergic than non-allergic patients (p < 0.05). We also observed a slight worsening trend of global satisfaction of patients. Our study confirms the minor discomfort and low risk of side effects of RVTR. Our data showed good efficacy of the procedure in the majority of patients for at least 36 months after surgery, and in fact in this time period the cumulative probability to remain relapse-free was up to 0.8. In the following 2 years, we observed a worse temporal trend in term of recurrence rate, and in particular in allergic patients with a significant difference vs non-allergic individuals (p < 0.05).

    Objective To review the authors’ experience with local excision of early rectal cancers to assess the effectiveness of initial treatment and of salvage surgery. Summary Background Data Local excision for rectal cancer is appealing for its low morbidity and excellent functional results. However, its use is limited by inability to assess regional lymph nodes and uncertainty of oncologic outcome. Methods Patients with T1 and T2 adenocarcinomas of the rectum treated by local excision as definitive surgery between 1969 to 1996 at the authors’ institution were reviewed. Pathology slides were reviewed. Among 125 assessable patients, 74 were T1 and 51 were T2. Thirty-one patients (25%) were selected to receive adjuvant radiation therapy. Fifteen of these 31 patients received adjuvant radiation in combination with 5-fluorouracil chemotherapy. Median follow-up was 6.7 years. One hundred fifteen patients (92%) were followed until death or for greater than 5 years, and 69 patients (55%) were followed until death or for greater than 10 years. Recurrence was recorded as local, distant, and overall. Survival was disease-specific. Results Ten-year local recurrence and survival rates were 17% and 74% for T1 rectal cancers and 26% and 72% for T2 cancers. Median time to relapse was 1.4 years (range 0.4–7.0) for local recurrence and 2.5 years (0.8–7.5) for distant recurrence. In patients receiving radiotherapy, local recurrence was delayed (median 2.1 years vs. 1.1 years), but overall rates of local and overall recurrence and survival rates were similar to patients not receiving radiotherapy. Among 26 cancer deaths, 8 (28%) occurred more than 5 years after local excision. On multivariate analysis, no clinical or pathologic features were predictive of local recurrence. Intratumoral vascular invasion was the only significant predictor of survival. Among 34 patients who developed tumor recurrence, the pattern of first clinical recurrence was predominantly local: 50% local only

    longer-term (approximately 25-day) full-scale tests on two different units. The longer-term tests were conducted to confirm the effectiveness of the sorbents tested over extended operation on two different boilers, and to determine balance-of-plant impacts. The first long-term test was conducted on FirstEnergy's BMP, Unit 3, and the second test was conducted on AEP's Gavin Plant, Unit 1. The Gavin Plant testing provided an opportunity to evaluate the effects of sorbent injected into the furnace on SO{sub 3} formed across an operating SCR reactor. This report presents the results from those long-term tests. The tests determined the effectiveness of injecting commercially available magnesium hydroxide slurry (Gavin Plant) and byproduct magnesium hydroxide slurry (both Gavin Plant and BMP) for sulfuric acid control. The results show that injecting either slurry could achieve up to 70 to 75% overall sulfuric acid removal. At BMP, this overall removal was limited by the need to maintain acceptable electrostatic precipitator (ESP) particulate control performance. At Gavin Plant, the overall sulfuric acid removal was limited because the furnace injected sorbent was less effective at removing SO{sub 3} formed across the SCR system installed on the unit for NOX control than at removing SO{sub 3} formed in the furnace. The long-term tests also determined balance-of-plant impacts from slurry injection during the two tests. These include impacts on boiler back-end temperatures and pressure drops, SCR catalyst properties, ESP performance, removal of other flue gas species, and flue gas opacity. For the most part the balance-of-plant impacts were neutral to positive, although adverse effects on ESP performance became an issue during the BMP test.

    Background In recent years, patients over 80 years of age have been a growing group of individuals referred to cardiac surgeons. They pose a serious challenge and usually require a multidisciplinary approach. Aim The aim of this study was to evaluate the early and late outcomes of cardiosurgical treatment of patients over 80 years of age suffering from coronary artery disease and aortic stenosis. Material and methods The study involved 96 patients aged over 80 years treated between January, 2004 and December, 2012. The mortality and morbidity in the early postoperative period, as well as throughout the follow-up period, were analyzed. Results The majority of patients underwent isolated coronary artery bypass grafting (CABG) (58.3%; Group I), while 29.2% of them underwent an isolated aortic valve replacement (AVR) (Group II). Combined procedures (CABG + AVR) were carried out in 12.5% of patients (Group III). The mean operational risk calculated according to the logistic EuroSCORE was 11.6%, 11.9%, and 9.5%, respectively in Group I, Group II and in Group III. In the early postoperative period, 4 patients died (all from Group I). The 30-day mortality rate was 4.2% and the morbidity rate was 56.3%. During the post-discharge follow-up period that lasted from 1 to 100 months, 4 patients died (2 from Group I and 2 from Group III). The 2-year probability of survival was 91.9 ± 3.0%. During the last follow-up clinical assessment, half of the patients were asymptomatic. Conclusions The perioperative mortality of the patients is acceptably and markedly lower than that predicted by the logistic EuroSCORE calculator. However, the complication rate, particularly in the early postoperative period, is relatively high. PMID:26336430

    NASA’s Heliophysics Data Management Policy calls for discipline-specific “final archives,” which will be responsible for the long-term archiving and service of Heliophysics mission data. Long-term archival functions, such as periodic revalidation of the data and migration to newer storage media when appropriate, have never been part of the Solar Data Analysis Center core capabilities. We also recognize that the largest space solar physics data set, the SDO AIA and HMI data at the Stanford Joint Science and Operations Center (JSOC), will eventually need preservation and long-term access, as will the potentially much larger data archive of DKIST observations. We have carried out a study of data archiving best practices in other disciplines and organizations, including NASA’s Space Physics Data Facility (SPDF), the National Institute of Standards and Technology (NIST), and private industry, and report on the lessons learned and possible cost models. We seek input from the broader solar physics community on the relative value of various levels of preservation effort.

    The Subsurface Disposal Area (SDA) of the Radioactive Waste Management Complex (RWMC) located at the Idaho National Engineering and Environmental Laboratory (INEEL) contains neutron-activated metals from non-fuel, nuclear reactor core components. The Long-Term Corrosion/Degradation (LTCD) Test is designed to obtain site-specific corrosion rates to support efforts to more accurately estimate the transfer of activated elements to the environment. The test is using two proven, industry-standard methods—direct corrosion testing using metal coupons, and monitored corrosion testing using electrical/resistance probes—to determine corrosion rates for various metal alloys generally representing the metals of interest buried at the SDA, including Type 304L stainless steel, Type 316L stainless steel, Inconel 718, Beryllium S200F, Aluminum 6061, Zircaloy-4, low-carbon steel, and Ferralium 255. In the direct testing, metal coupons are retrieved for corrosion evaluation after having been buried in SDA backfill soil and exposed to natural SDA environmental conditions for times ranging from one year to as many as 32 years, depending on research needs and funding availability. In the monitored testing, electrical/resistance probes buried in SDA backfill soil will provide corrosion data for the duration of the test or until the probes fail. This report provides an update describing the current status of the test and documents results to date. Data from the one-year and three-year results are also included, for comparison and evaluation of trends. In the six-year results, most metals being tested showed extremely low measurable rates of general corrosion. For Type 304L stainless steel, Type 316L stainless steel, Inconel 718, and Ferralium 255, corrosion rates fell in the range of “no reportable” to 0.0002 mils per year (MPY). Corrosion rates for Zircaloy-4 ranged from no measurable corrosion to 0.0001 MPY. These rates are two orders of magnitude lower than those specified in

    It is reported on experiences and results in 317 patients with altogether 690 implantations of pacemakers from 1963 to 1974 and under comparison and with reference to the up to now existing long-term results published in literature state and tendency of the medical and technical development of the electric heart stimulation are discussed. The average age of outpatients was 62.9 years with a peak of age of 46% in the 7th decade of life. 60% were male patients, 40% female ones. With about 50% the constant total atrioventricular block was the most frequent indication. 63% of the familiar types of pacemakers were biotronic apparatuses, 36% of them with fixed frequency. The average duration of the function of all apparatuses was calculated with 20.1 months. Hereby the biotronic types had the longest average function times of 26.7 months (frequency fixed) or 26.3 months (regulated). In 373 reimplantations is shown that 2.17 apparatuses were implanted in each patient. The total number of complications was 21.2% related to the total number of implantations. With 8.9% breaks of the cable were in the first place in myocardial electrodes. Dislocations of transvenous electrodes were observed only in 4.5% of our cases. With 5.8% pressure necroses and infections were the cause of complications stood in the second place concerning frequency. The total lethality was 23.7% with an age peak of 38% in the 8th decade of life. 13.4% of the cases of death belong to an early lethality with a prevailing part of epicardial implantations. In our patients the cumulative survival rate was after 1 year 89.3%, after 5 years 62.3% and after 8 years 47.7%. The 50% survival rate was ca. 7.3 years. In comparison to the population of the same age the average expectance of life is transgressed by about 6 years. The prolongation of the survival time by electrostimulation compared with the conservative treatment of the total atrioventricular block with Adams-Stokes-syndrome is the essential result of

    The aim of this study was to document the clinical features and long-term outcomes in 43 cases of bilateral breast carcinoma. All the women were diagnosed by a single surgeon who had evaluated 13,443 patients with breast-related complaints over a 40-year period. At the initial cancer diagnosis, 28 patients (65%) were of premenopausal age (< or = 46 years; group 1) and 15 (35%) were postmenopausal (> 46 years; group 2). The median interval between initial and subsequent cancer was 24 months (range, 12-288 months) in group 1 and 20 months (range, 14-252 months) in group 2 (P > 0.05). The distribution of initial cancer types based on pathological examination was ductal adenocarcinoma in 28 (65%) cases; lobular carcinoma in 5 (12%) cases; comedocarcinoma in 5 (12%) cases; papillary carcinoma in 2 (4.5%) cases; papillary combined with squamous cell carcinoma in 1 (2%) case; and lobular combined with medullary carcinoma in 2 (4.5%) cases. There were no significant differences between the groups with respect to the distribution of types of surgery used for the initial and subsequent carcinomas. Tumor locations were symmetrical in 26 (60%) patients. The mean palpable mass sizes for the initial and subsequent tumors in group 1 were 3 +/- 1.4 (range, 1-8 cm) and 1.3 +/- 0.5 cm (range, 1-2 cm), respectively. The corresponding means for group 2 were 2.3 +/- 1.8 (range, 0.9-7 cm) and 1.3 +/- 0.5 cm (range, 1-2 cm). The 10- and 20-year disease-free survival rates for group 1 versus group 2 were 32% versus 27% and 10% versus 8%, respectively. The rates of axillary lymph node metastasis from the primary cancer in groups 1 and 2 were statistically similar; however, the rate of axillary lymph node metastasis from subsequent cancer in group 1 was significantly higher than that in group 2 (P = 0.02). The lactation period (after each child born) in group 1 was significantly longer than that in group 2 (P = 0.04). Group 1 had a higher rate of distant metastasis at 20 years (P = 0

    Open-label extensions [studies SP516 (NCT00501969) and SP715 (NCT00594386)] of the CLEOPATRA-PD and PREFER studies were conducted to evaluate the safety, tolerability and efficacy of the dopaminergic agonist, rotigotine, over several years of follow-up in patients with advanced Parkinson's disease (PD). Eligible subjects completing the double-blind trials received open-label adjunctive rotigotine (≤16 mg/24 h) for up to 4 and 6 years in Studies SP516 and SP715, respectively. Safety and tolerability were assessed using adverse events, vital signs and laboratory parameters, and efficacy assessed using the unified Parkinson's disease rating scale (UPDRS). Of the 395 and 258 patients enrolled in the SP516 and SP715 studies, 48 and 45 % completed, respectively. Adverse events were typically dopaminergic effects [e.g., somnolence (18-25 %/patient-year), insomnia (5-7 %/patient-year), dyskinesias (4-8 %/patient-year) and hallucinations (4-8 %/patient-year)], or related to the transdermal application of a patch (application site reactions: 14-15 %/patient-year). There were no clinically relevant changes in vital signs or laboratory parameters in either study. Mean UPDRS part II (activities of daily living) and part III (motor function) total scores improved from double-blind baseline during dose titration, then gradually declined over the maintenance period. In study SP516, mean UPDRS part II and III total scores were 0.8 points above and 2.8 points below double-blind baseline, respectively, at end of treatment. In study SP715, mean UPDRS part II and III total scores were 4.1 points above and 0.2 points below baseline, respectively, at end of treatment. In these open-label studies, adjunctive rotigotine was efficacious with an acceptable safety and tolerability profile in patients with advanced PD for up to 6 years.

    Syndesmotic disruption occurs in more than 10% of ankle fractures. Operative treatment with syndesmosis screw fixation has been successfully performed for decades and is considered the gold standard of treatment. Few studies have reported the long-term outcomes of syndesmosis injuries. This study investigated long-term patient-reported, radiographic, and functional outcomes of syndesmosis injuries treated with screw fixation and subsequent timed screw removal. A retrospective cohort study was carried out at a Level I trauma center. The study group included 43 patients who were treated for ankle fractures with associated syndesmotic disruptions between December 2001 and May 2011. The study included case file reviews, self-reported questionnaires, radiologic reviews, and clinical assessments. At 5.1 (±1.76) years after injury, 60% of participants had pain, 26% had degenerative changes, 51% had loss of tibiofibular overlap, and 33% showed medial clear space widening. Retained syndesmotic positions on radiographs were linked to better self-reported outcomes. There is an inversely proportional relation between age at the time of injury and satisfaction with the outcome of the ankle fracture as well as a directly proportional relation between age at the time of injury and pain compared with the preinjury state. Optimal restoration and preservation of the syndesmosis is crucial. Syndesmotic disruption is associated with poor long-term outcomes after ankle fracture. Greater age is a risk factor for chronic pain and dissatisfaction with the outcome of ankle fracture and syndesmosis injury. Therefore, patient education to facilitate realistic expectations about recovery is vital, especially in older patients. PMID:26558664

    2016-10-01

    To date, the appropriate management of diverticular disease is still controversial. The American Society of Colon and Rectal Surgeons declared that the decision between conservative or surgical approach should be taken by a case-by-case evaluation. There is still lack of evidence in literature about long-term outcomes after elective sigmoid resection for diverticular disease. Considering the potentially key role of the surgical technique in long-term outcomes, there is the need for surgeons to define strict rules to standardize the surgical technique. Currently there are 5 areas of debate in elective surgery for diverticular disease: laparoscopic versus open approach, the site of the proximal and distal colonic division, the vascular approach and the mobilization of the splenic flexure. The purpose of this paper is to review existing knowledge about technical aspects, which represent how the surgeon is able to affect the long-term results. PMID:27622373

    damage that would result from acid etching, base damage (as a result of a sludge spill or splatter), gamma radiation damage, and/or accidental scratching (due to manipulator/tool contact). Although identified as a potential solution, the Phase 1 testing was relatively short-term with exposure times up to 1-2 months for the acid and gamma radiation tests. Phase 2 testing included longer exposure times for the acid resistance (up to 456 days) and gamma radiation exposure (700 days with a cumulative gamma dose of {approx}3.1 x 10{sup 5} rad) assessments. The tear-off system continued to perform well in these longer-term acid resistance testing and gamma exposure conditions. Complete removal of the tear-offs after these long-term exposure times indicate that not only could visual clarity be restored but the mechanical integrity could be retained. The results also provided insight into the ability of the ProTec tear-off system to withstand the chemical and physical abuses expected in off-normal shielded cells operations. The conceptual erasing of scratches or marks by excessive manipulator abuse was demonstrated in the SRNL Shielded Cells mock-up facility through the removal of the outer layer tear-off with manipulators. In addition, the Phase 2 testing included an in-situ assessment of a prototype tear-off system in the DWPF Sampling Cells where the system was exposed to actual field conditions including radioactive sources, acidic and basic environments, dusting, and chemical cleaning solutions over a 5-6 month period. DWPF personnel were extremely satisfied with the performance (including the successful removal of 3 layers with manipulators) of the ProTec tear-off system under actual field conditions. The successful removal of the outer layer tear-offs with the manipulator, using tabs not specifically designed for remote operations, demonstrates that the system is 'manipulator-friendly' and could be implemented in a remote environment. The ability to remove the outer layer

    Based on solid scientific evidence, new generation drug-eluting stents (DES) have become established as the standard of care in interventional cardiology. With at least similar safety and superior efficacy over uncoated bare metal stents (BMS) in various scenarios and including patients with increased bleeding risk, there are probably no remaining indications favoring the use of BMS. Additional developments regarding the platform, drug elution characteristics and polymer design were aimed at optimizing DES with even better outcomes. Although there is no lack of new variations, none has proven to be superior and several non-inferiority trials lacked statistical power, which precludes the label third generation (over second generation or new generation DES). While it is recognized that potential long-term advantages of bioresorbable scaffolds cannot be expected at this stage from the current ABSORB III trial, the safety and efficacy are encouraging. Beyond procedural aspects, such as intracoronary imaging, variations in duration of antiplatelet therapy should help to improve outcomes but still require careful individual weighting of ischemic vs. bleeding risk.

    Tennis elbow (TE) is one of the commonest myotendinosis. Different treatment options are available and autologous blood injection has emerged as the one of the acceptable modalities of treatment. Long term studies over a larger group of patients are however lacking. The purpose of this study was to evaluate these patients on longer durations. One-hundred and twenty patients of TE, who failed to respond to conventional treatment including local steroid injections were taken up for this prospective study over the period from year 2005 to 2011 and were followed up for the minimum of 3 years (range 3-9 years). Two mL of autologous blood was taken from the ipsilateral limb and injected into the lateral epicondyle. The effectiveness of the procedure was assessed by Pain Rating Sscale and Nirschl Staging, which was monitored before the procedure, at first week, monthly for first three months, at 6 months and then 3 monthly for first year, six monthly for next 2 years and then yearly. Statistical analysis was done and a P value of <0.05 was taken as significant. The patients (76 females and 44 males) were evaluated after procedure. The mean age group was 40.67±8.21. The mean follow up was 5.7±1.72 (range 3 to 9 years). The mean pain score and Nirschl stage before the procedure was 3.3±0.9 and 6.2±0.82 respectively. At final follow up the pain score and Nirschl were 1.1±0.9 and 1.5±0.91 respectively. Autologous blood injection was found to be one of the modalities for treatment of TE. Being cheap, available and easy method of treatment, it should be considered as a treatment modality before opting for the surgery. Universal guidelines for the management of tennis elbow should be made as there is lot of controversy regarding the treatment. PMID:25568727

    Experience suggests that many celiac patients suffer from persistent symptoms despite a long-term gluten-free diet (GFD). We investigated the prevalence and severity of these symptoms in patients with variable duration of GFD. Altogether, 856 patients were classified into untreated (n = 128), short-term GFD (1-2 years, n = 93) and long-term GFD (≥3 years, n = 635) groups. Analyses were made of clinical and histological data and dietary adherence. Symptoms were evaluated by the validated GSRS questionnaire. One-hundred-sixty healthy subjects comprised the control group. Further, the severity of symptoms was compared with that in peptic ulcer, reflux disease, inflammatory bowel disease (IBD) and irritable bowel syndrome (IBS). Altogether, 93% of the short-term and 94% of the long-term treated patients had a strict GFD and recovered mucosa. Untreated patients had more diarrhea, indigestion and abdominal pain than those on GFD and controls. There were no differences in symptoms between the short- and long-term GFD groups, but both yielded poorer GSRS total score than controls (p = 0.03 and p = 0.05, respectively). Furthermore, patients treated 1-2 years had more diarrhea (p = 0.03) and those treated >10 years more reflux (p = 0.04) than controls. Long-term treated celiac patients showed relatively mild symptoms compared with other gastrointestinal diseases. Based on our results, good response to GFD sustained in long-term follow-up, but not all patients reach the level of healthy individuals. PMID:27428994

    Objective To determine the rate of complications of ileoanal pouch anastomosis, their treatment and their influence on a successful outcome. Design A computerized database and chart review. Setting Three academic tertiary care health centres. Patients All 239 patients admitted for surgery between 1981 and 1994 with a diagnosis of ulcerative colitis and familial adenomatosis coli. Interventions Sphincter-saving total proctocolectomy and construction of either S-type or J-type ileoanal reservoir. Outcome measures Indications, early and late complications, incidence of pouch excision. Results Of the 239 patients, 228 (95.4%) were operated on for ulcerative colitis and 11 (4.6%) for familial polyposis coli. One patient in each group was found to have a carcinoma not previously diagnosed. Twenty-eight patients had poor results: in 17 (7.1%) the ileostomy was never closed or was re-established because of pelvic sepsis or complex fistulas, sclerosing cholangitis or severe diarrhea; 11 (4.6%) patients required excision of the pouch because of anal stenosis, perirectal abscess-fistula or rectovaginal fistula. Three patients died — of suicide, and complications of liver transplantation and HIV infection. Thus, 208 patients maintained a functioning pouch. The early complication rate (within 30 days of operation) was 57.7% (138 patients) and the late complication rate was 52.3% (125 patients). Pouchitis alone did not lead to failure or pouch excision. Emptying difficulties in 25 patients with anal stenosis were helped in 2 by resorting to intermittent catheterization. Patients with indeterminate colitis had a higher rate of anorectal septic complications, and all patients having Crohn’s disease after pouch construction had complicated courses. Conclusions The complication rate associated with ileoanal pouch anastomosis continues to be relatively high despite increasing experience with this technique. Overall, however, a satisfactory outcome was obtained in 87% of patients

    Many celiac disease patients tolerate oats, but limited data are available on its long-term consumption. This was evaluated in the present study, focusing on small-bowel mucosal histology and gastrointestinal symptoms in celiac adults maintaining a strict gluten-free diet with or without oats. Altogether 106 long-term treated celiac adults were enrolled for this cross-sectional follow-up study. Daily consumption of oats and fiber was assessed, and small-bowel mucosal morphology and densities of CD3+, αβ+ and γσ+ intraepithelial lymphocytes determined. Gastrointestinal symptoms were assessed by a validated Gastrointestinal Symptom Rating Scale questionnaire. Seventy (66%) out of the 106 treated celiac disease patients had consumed a median of 20 g of oats (range 1-100 g) per day for up to eight years; all consumed oat products bought from general stores. Daily intake and long-term consumption of oats did not result in small-bowel mucosal villous damage, inflammation, or gastrointestinal symptoms. Oat-consumers had a significantly higher daily intake of fiber than those who did not use oats. Two thirds of celiac disease patients preferred to use oats in their daily diet. Even long-term ingestion of oats had no harmful effects.

    Purpose: The aim of this study was to evaluate the effectiveness of low-dose-rate brachytherapy for local control and relapse-free survival in squamous cell and basal cell carcinomas of the lips. We compared two groups: one with tumors on the skin and the other with tumors on the lip. Patients and methods: All patients had been treated at Claudius Regaud Cancer Centre from 1990 to 2008 for squamous cell or basal cell carcinoma. Low-dose-rate brachytherapy was performed with iridium 192 wires according to the Paris system rules. On average, the dose delivered was 65 Gy. Results: 172 consecutive patients were included in our study; 69 had skin carcinoma (squamous cell or basal cell), and 92 had squamous cell mucosal carcinoma. The average follow-up time was 5.4 years. In the skin cancer group, there were five local recurrences and one lymph node recurrence. In the mucosal cancer group, there were ten local recurrences and five lymph node recurrences. The 8-year relapse-free survival for the entire population was 80%. The 8-year relapse-free survival was 85% for skin carcinoma 75% for mucosal carcinoma, with no significant difference between groups. The functional results were satisfactory for 99% of patients, and the cosmetic results were satisfactory for 92%. Maximal toxicity observed was Grade 2. Conclusions: Low-dose-rate brachytherapy can be used to treat lip carcinomas at Stages T1 and T2 as the only treatment with excellent results for local control and relapse-free survival. The benefits of brachytherapy are also cosmetic and functional, with 91% of patients having no side effects.

    Objective To evaluate early and mid-term results in patients undergoing proximal thoracic aortic redo surgery. Methods We analyzed 60 patients (median age 60 years, median logistic EuroSCORE 40) who underwent proximal thoracic aortic redo surgery between January 2005 and April 2012. Outcome and risk factors were analyzed. Results In hospital mortality was 13%, perioperative neurologic injury was 7%. Fifty percent of patients underwent redo surgery in an urgent or emergency setting. In 65%, partial or total arch replacement with or without conventional or frozen elephant trunk extension was performed. The preoperative logistic EuroSCORE I confirmed to be a reliable predictor of adverse outcome- (ROC 0.786, 95%CI 0.64–0.93) as did the new EuroSCORE II model: ROC 0.882 95%CI 0.78–0.98. Extensive individual logistic EuroSCORE I levels more than 67 showed an OR of 7.01, 95%CI 1.43–34.27. A EuroSCORE II larger than 28 showed an OR of 4.44 (95%CI 1.4–14.06). Multivariate logistic regression analysis identified a critical preoperative state (OR 7.96, 95%CI 1.51–38.79) but not advanced age (OR 2.46, 95%CI 0.48–12.66) as the strongest independent predictor of in-hospital mortality. Median follow-up was 23 months (1–52 months). One year and five year actuarial survival rates were 83% and 69% respectively. Freedom from reoperation during follow-up was 100%. Conclusions Despite a substantial early attrition rate in patients presenting with a critical preoperative state, proximal thoracic aortic redo surgery provides excellent early and mid-term results. Higher EuroSCORE I and II levels and a critical preoperative state but not advanced age are independent predictors of in-hospital mortality. As a consequence, age alone should no longer be regarded as a contraindication for surgical treatment in this particular group of patients. PMID:23469220

    Using validated equipment for ABPM (by the indirect, intermittent, oscillometric and/or auscultatory method) reproducible results for day- and night-time blood-pressure, early morning readings, and blood-pressure variability may be obtained. The frequency of recordings should be about 15-min while awake and about 30-min during sleep-time, with at least 50 validated readings in 24-h to get an informative recording. Standardization could be achieved for the normotensive mean day-time value (upper limit 135/85 mmHg) and mean night-time recording (at least minus 10% compared to the day-time mean value). Using ABPM the diagnosis of arterial hypertension may be optimized, e.g. patients with white-coat hypertension could be discovered as well as those with diminished day-night rhythm ("non-dippers"); with the latter condition cerebral or myocardial damage might occur as consequence of primary hypertension; even more so, secondary hypertension may be discovered in patients with "non-dipper" constellation. In respect to therapy, a "profile-adjusted" medication may be obtained by ABPM; side-effects, which could be produced by "overtreatment", may be discovered. Since day- as well as night-time values, possibly even early morning pressures and the blood-pressure variability are positively correlated to cerebral and cardiovascular complications, ABPM becomes an important prognostic tool.

    Objective HIV-infected patients in Africa are vulnerable to severe recurrent infection with Streptococcus pneumoniae, but no effective preventive strategy has been developed. We set out to determine which factors influence in-hospital mortality and long-term survival of Malawians with invasive pneumococcal disease. Design, setting and patients Acute clinical features, inpatient mortality and long-term survival were described among consecutively admitted hospital patients with S. pneumoniae in the blood or cerebrospinal fluid. Factors associated with inpatient mortality were determined, and patients surviving to discharge were followed to determine their long-term outcome. Results A total of 217 patients with pneumococcal disease were studied over an 18-month period. Among these, 158 out of 167 consenting to testing (95%) were HIV positive. Inpatient mortality was 65% for pneumococcal meningitis (n = 64), 20% for pneumococcaemic pneumonia (n = 92), 26% for patients with pneumococcaemia without localizing signs (n = 43), and 76% in patients with probable meningitis (n = 17). Lowered consciousness level, hypotension, and age exceeding 55 years at presentation were associated with inpatient death, but not long-term outcome in survivors. Hospital survivors were followed for a median of 414 days; 39% died in the community during the study period. Outpatient death was associated with multilobar chest signs, oral candidiasis, and severe anaemia as an inpatient. Conclusion Most patients with pneumococcal disease in Malawi have HIV co-infection. They have severe disease with a high mortality rate. At discharge, all HIV-infected adults have a poor prognosis but patients with multilobar chest signs or anaemia are at particular risk.

    Background The Global Initiative for Obstructive Lung Diseases (GOLD) defines COPD as a disease that is usually progressive. GOLD also provides a spirometric classification of airflow limitation. However, little is known about the long-term changes of patients in different GOLD grades. Objective Explore the proportion and characteristics of COPD patients that change their spirometric GOLD grade over long-term follow-up. Methods Patients alive for at least 8 years since recruitment and those who died with at least 4 years of repeated spirometric measurements were selected from the BODE cohort database. We purposely included the group of non survivors to avoid a “survival selection” bias. The proportion of patients that had a change (improvement or worsening) in their spirometric GOLD grading was calculated and their characteristics compared with those that remained in the same grade. Results A total of 318 patients were included in the survivor and 217 in the non-survivor groups. Nine percent of survivors and 11% of non survivors had an improvement of at least one GOLD grade. Seventy one percent of survivors and non-survivors remained in the same GOLD grade. Those that improved had a greater degree of airway obstruction at baseline. Conclusions In this selected population of COPD patients, a high proportion of patients remained in the same spirometric GOLD grade or improved in a long-term follow-up. These findings suggest that once diagnosed, COPD is usually a non-progressive disease. PMID:27100872

    To determine the long-term health and function of transplanted dopamine neurons in Parkinson's disease (PD) patients, the expression of dopamine transporters (DATs) and mitochondrial morphology were examined in human fetal midbrain cellular transplants. DAT was robustly expressed in transplanted dopamine neuron terminals in the reinnervated host putamen and caudate for at least 14 years after transplantation. The transplanted dopamine neurons showed a healthy and nonatrophied morphology at all time points. Labeling of the mitochondrial outer membrane protein Tom20 and α-synuclein showed a typical cellular pathology in the patients' own substantia nigra, which was not observed in transplanted dopamine neurons. These results show that the vast majority of transplanted neurons remain healthy for the long term in PD patients, consistent with clinical findings that fetal dopamine neuron transplants maintain function for up to 15-18 years in patients. These findings are critically important for the rational development of stem-cell-based dopamine neuronal replacement therapies for PD.

    Background We evaluated early and long-term results after heart transplantation (HTPL). Methods One hundred five consecutive patients (male:female=80:25) who underwent HTPL between 1994 and 2013 were enrolled. Based on the changes in immunosuppressive regimen, the study patients were divided into two groups. Early and long-term clinical outcomes were evaluated and compared between the patients who underwent HTPL before (group E, n=41) and after July 2009 (group L, n=64). The group L patients were older (p<0.001), had higher incidence of hypertension (p=0.001) and chronic kidney disease (p<0.001), and more frequently needed preoperative mechanical ventilation (p=0.027) and mechanical circulatory support (p=0.014) than the group E patients. Results Overall operative mortality was 3.8%, and postoperative morbidities included acute kidney injury (n=31), respiratory complications (n=16), reoperation for bleeding (n=15) and wound complications (n=10). There were no significant differences in early results except acute kidney injury between group E and group L patients. Overall survival rates at 1, 5, and 10 years were 83.8%, 67.7%, and 54.9%, respectively, with no significant difference between the two patient groups. Rejection-free rates at 1 and 5 years were 63.0% and 59.7%, respectively; rates were significantly higher in group L than in group E (p<0.001). Conclusion Despite increased preoperative comorbidities, group L patients showed similar early and long-term outcomes and significantly higher rejection-free rates when compared with group E patients.

    Purpose: To evaluate the long-term efficacy of concurrent radiotherapy with mitomycin-C (MMC)-based or cisplatin (CP)-based combinations in a cohort of patients with locally advanced anal canal carcinoma. Methods and Materials: Between 1988 and 2000, 179 patients with locally advanced anal canal carcinoma were treated at the Instituto Nacional de Cancer with two cycles of chemotherapy during Weeks 1 and 5 of radiotherapy. 5-Fluorouracil (750 mg/m{sup 2} 120-hour infusion or 1,000 mg/m{sup 2} 96-hour infusion) plus CP (100 mg/m{sup 2}) on the first day of each cycle or MMC (10-15 mg/m{sup 2}) on the first day of Cycle 1 was administered concurrent with radiotherapy (total dose, 55-59.4 Gy). Of the 179 patients, 60% were included from a randomized trial initiated at the Instituto Nacional de Cancer in 1991 that compared concurrent chemoradiotherapy with MMC vs. CP. Results: The median follow-up for the whole chemoradiotherapy group was 83 months. The median patient age was 58 years, 57% had Stage T3-T4 tumors, and 35% had N-positive disease. The 5-year cumulative colostomy rate was not significantly different between the CP group (22%) and MMC group (29%; p = .28). The actuarial 10-year overall survival and disease-free survival rate for the CP group was 54% and 49% and for the MMC group was 52% and 53%, respectively (p = .32 and p = .92, respectively). On multivariate analysis, male gender (p = .042) and advanced Stage T3-T4 disease (p <.0001) were statistically significant for worse disease-free survival. Stage T3-T4 (p = .039) and N+ (p = .039) disease remained independently significant for overall survival. Conclusion: Long-term follow-up has confirmed the good results of chemoradiotherapy with CP plus 5-fluorouracil, which seem to provide results equivalent to those with MMC plus 5-fluorouracil.

    Primary renal lymphoma (PRL) is a rare disease of which the etiology and pathogenesis remain controversial, and there is currently no standard treatment for it. We present the results of a long-term followup of two patients who were diagnosed with PRL and treated with cyclophosphamide, adriamycin, vincristine, prednisolone and rituximab (CHOP + R) regimen. Both patients reached a complete response, and there is no evidence of recurrence after 4.5- and 5-year followup periods. Based on our experience and other recently published studies, we recommend the combination of CHOP + rituximab as the elective treatment for this disease. To our knowledge, this is the longest followup period with a complete response that has been reported with this modality of treatment. PMID:22997596

    Purpose: To assess the long-term results of radiation therapy (RT) when added preoperatively to systemic chemotherapy in patients with locally advanced gastric cancer. Methods and Materials: Patients presenting with T3-4 or N+ gastric cancer received two cycles of cisplatin 100 mg/m{sup 2} d1, 5FU 800 mg/m{sup 2} d1-4, and Leucovorin 60 mg twice daily d1-4; one cycle before and one concomitantly with hyperfractionated RT (median dose, 38.4; range, 31.2-45.6 Gy). All patients underwent a total or subtotal gastrectomy with D2 lymph node resection. Results: Nineteen patients were accrued and 18 completed the neoadjuvant therapeutic program. All patients were subsequently operated and no fatality occurred. At a mean follow-up of 8 years for the surviving patients, no severe late toxicity was observed. The 5-year locoregional control, disease-free, and overall survival were of 85%, 41%, and 35%, respectively. The peritoneum was the most frequent site of relapse. Among long terms survivors, no severe (Radiation Therapy Oncology Group Grade 3-4) late complication was reported. Conclusions: The present neoadjuvant treatment does not seem to increase the operative risk, nor the late side effects. The encouraging locoregional control rate suggests that the neoadjuvant approach should be considered for future trials in locally advanced gastric cancer. Also, the frequency of peritoneal recurrence stresses the need for a more efficient systemic or intraperitoneal treatment.

    The management of de Quervain's disease (DD) is nonoperative in the first instance, but surgery should be considered if conservative measures fail. We present the long-term results of operative treatment of DD. From July 1988 to July 1998, 94 consecutive patients with DD were treated operatively by a single surgeon. There were 80 women and 14 men. Average age at the time of operation was 47.4 years (range 22-76). The right wrist was involved in 43 cases, the left in 51 cases. All operations were done under tourniquet control with local infiltration anaesthesia using a longitudinal incision and partial resection of the extensor ligament. There were six perioperative complications, including one superficial wound infection, one delayed wound healing, and four transient lesions of the radial nerve. A successful outcome was achieved in all cases with negative Finkelstein's test. Simple decompression of both tendons and partial resection of the extensor ligament with a maximum of 3 mm can be recommended in operative treatment of DD with excellent long-term results.

    Background On the range of diagnoses, course of treatment, and long-term outcome in patients who chose to receive homeopathic medical treatment very little is known. We investigated homeopathic practice in an industrialized country under everyday conditions. Methods In a prospective, multicentre cohort study with 103 primary care practices with additional specialisation in homeopathy in Germany and Switzerland, data from all patients (age >1 year) consulting the physician for the first time were observed. The main outcome measures were: Patient and physician assessments (numeric rating scales from 0 to 10) and quality of life at baseline, and after 3, 12, and 24 months. Results A total of 3,981 patients were studied including 2,851 adults (29% men, mean age 42.5 ± 13.1 years; 71% women, 39.9 ± 12.4 years) and 1,130 children (52% boys, 6.5 ± 3.9 years; 48% girls, 7.0 ± 4.3 years). Ninety-seven percent of all diagnoses were chronic with an average duration of 8.8 ± 8 years. The most frequent diagnoses were allergic rhinitis in men, headache in women, and atopic dermatitis in children. Disease severity decreased significantly (p < 0.001) between baseline and 24 months (adults from 6.2 ± 1.7 to 3.0 ± 2.2; children from 6.1 ± 1.8 to 2.2 ± 1.9). Physicians' assessments yielded similar results. For adults and young children, major improvements were observed for quality of life, whereas no changes were seen in adolescents. Younger age and more severe disease at baseline were factors predictive of better therapeutic success. Conclusion Disease severity and quality of life demonstrated marked and sustained improvements following homeopathic treatment period. Our findings indicate that homeopathic medical therapy may play a beneficial role in the long-term care of patients with chronic diseases. PMID:16266440

    Study question What is the long term efficacy of betahistine dihydrochloride on the incidence of vertigo attacks in patients with Meniere’s disease, compared with placebo? Methods The BEMED trial is a multicentre, double blind, randomised, placebo controlled, three arm, parallel group, phase III, dose defining superiority trial conducted in 14 German tertiary referral centres (for neurology or ear, nose, and throat). Adults aged 21-80 years (mean age 56 years) with definite unilateral or bilateral Meniere’s disease were recruited from March 2008 to November 2012. Participants received placebo (n=74), low dose betahistine (2×24 mg daily, (n=73)), or high dose betahistine (3×48 mg daily, (n=74)) over nine months. The primary outcome was the number of attacks per 30 days, based on patients’ diaries during a three month assessment period at months seven to nine. An internet based randomisation schedule performed a concealed 1:1:1 allocation, stratified by study site. Secondary outcomes included the duration and severity of attacks, change in quality of life scores, and several observer-reported parameters to assess changes in audiological and vestibular function. Study answer and limitations Incidence of attacks related to Meniere’s disease did not differ between the three treatment groups (P=0.759). Compared with placebo, attack rate ratios were 1.036 (95% confidence interval 0.942 to 1.140) and 1.012 (0.919 to 1.114) for low dose and high dose betahistine, respectively. The overall monthly attack rate fell significantly by the factor 0.758 (0.705 to 0.816; P<0.001). The population based, mean monthly incidence averaged over the assessment period was 2.722 (1.304 to 6.309), 3.204 (1.345 to 7.929), and 3.258 (1.685 to 7.266) for the placebo, low dose betahistine, and high dose betahistine groups, respectively. Results were consistent for all secondary outcomes. Treatment was well tolerated with no unexpected safety findings. Without a control group of

    Objective. To determine the long-term stricture-free rate after visual internal urethrotomy following initial and follow-up urethrotomies. Methods. The records of all male patients who underwent direct visual internal urethrotomy for urethral stricture disease in our hospital between July 2004 and May 2012 were reviewed. The Kaplan-Meier method was used to analyze stricture-free probability after the first, second, third, fourth, and fifth urethrotomies. Results. A total of 301 patients were included. The overall stricture-free rate at the 36-month follow-up was 8.3% with a median time to recurrence of 10 months (95% CI of 9.5 to 10.5, range: 2-36). The stricture-free rate after one urethrotomy was 12.1% with a median time to recurrence of eight months (95% CI of 7.1-8.9). After the second urethrotomy, the stricture-free rate was 7.9% with a median time to recurrence of 10 months (95% CI of 9.3 to 10.6). After the third to fifth procedures, the stricture-free rate was 0%. There was no significant difference in the stricture-free rate between single and multiple procedures. Conclusion. The long-term stricture-free rate of visual internal urethrotomy is modest even after a single procedure.

    Refsum's disease is a rare autosomal recessive disorder of fatty acid metabolism. Poorly metabolized phytanic acid accumulates in fatty tissues, including myelin sheaths and internal organs, leading to retinitis pigmentosa, peripheral polyneuropathy, cerebellar ataxia, and renal, cardiac or liver impairment. Dietary restriction of phytanic acid in some cases is not sufficient to prevent acute attacks and stabilize the progressive course. Phytanic acid bound to large low density lipoproteins (LDL) and very low density lipoproteins (VLDL) molecules offers the possibility of extracorporeal elimination by lipid apheresis. We report on the long-term lipid apheresis treatment of four patients with severe Refsum's disease. Retinitis pigmentosa, peripheral polyneuropathy, cerebellar ataxia, anosmia, and sensorineural hearing loss were major symptoms exhibiting a progressive course. Lipid apheresis was performed for 5-13 years without severe complications. Maximum levels of phytanic acid before commencing chronic lipid apheresis were >300 mg/l. During steady state with lipid apheresis, mean phytanic acid before treatments was 87 mg/l and was reduced to 36 mg/l. Mean reduction rate was 59% per treatment. In all patients, abnormal motor nerve conduction velocity with signs of chronic denervation improved, morphological and functional stabilization of eye involvement was observed. Lipid apheresis prevented the extension of the disease to previously unaffected organs in three patients. Extracorporeal elimination of lipoprotein-phytanic acid complexes by lipid apheresis represents a pathophysiologically guided therapeutic approach, resulting in long-term improvement or stabilization of overall rehabilitation in patients with progressive Refsum's disease.

    Background and study aims: It has been postulated that the endoscopic ablation of Barrett’s esophagus can lead to complete eradication of the disease. This study was undertaken to evaluate the efficacy of endoscopic eradication therapy for Barrett’s esophagus and the rates of recurrence of intestinal metaplasia. Patients and methods: As part of an initial randomized controlled trial, patients with nondysplastic or low grade dysplastic Barrett’s esophagus underwent mucosal ablation. Following ablation, the patients had annual surveillance endoscopies. Recurrence was defined as the presence of intestinal metaplasia after initial complete eradication had been achieved. Results: A total of 28 patients with Barrett’s esophagus were followed for a mean of 6.4 years after ablation therapy. At baseline, the majority of the patients had nondysplastic Barrett’s esophagus (79 %). Initial complete eradication of intestinal metaplasia was achieved at a mean of 4.1 months. During long-term follow-up, initial recurrence of intestinal metaplasia was seen in 14 of the 28 of patients (50 %) at a mean of 40 months, and further maintenance ablation therapy was applied. At the final follow-up, 36 % of the patients had complete eradication of intestinal metaplasia, 18 % of the patients had intestinal metaplasia, and 21 % had died of unrelated causes; invasive esophageal adenocarcinoma had developed in 1 patient. Conclusions: The long-term results of this study demonstrate a recurrence rate of 50 % after complete eradication of Barrett’s esophagus with endoscopic eradication therapy. In addition, re-recurrence (in 36 %), even after further maintenance endoscopic eradication therapy, and deaths unrelated to the disease (21 %) occurred. Complete remission of Barrett’s esophagus appears to be a difficult goal to achieve. These results call into question the role of ablation in patients with low risk Barrett’s esophagus.

    Subtotal parathyroidectomy was performed in a consecutive series of 292 patients with primary hyperparathyroidism. We evaluated the long-term postoperative results during a period of 16 years. Patients ranged in age from 14 to 83 years and included 176 women and 116 men. Of these, 16% had a history of exposure to radiation in childhood or adolescence, while thyroid disease requiring some form of thyroidectomy coexisted in 91 (31%) of the patients. Histologic information on three or more parathyroid glands was obtained in 73% of the cases. We considered 285 patients (97.6%) cured after their first operation. The remaining seven patients (2.4%) had persistent hyperparathyroidism. However, five were cured after a sternum-splitting mediastinal exploration and one after a second neck exploration. The seventh remains hypercalcemic despite a subsequent mediastinal exploration. Temporary postoperative hypoparathyroidism occurred in 10% of our cases and permanent hypoparathyroidism in 1%. There have been no instances of recurrent hyperparathyroidism.

    This study explored burden and social networks in families of patients with schizophrenia or a long-term physical disease. It was carried out in 169 specialised units (mental health department, and units for the treatment of chronic heart, brain, diabetes, kidney, lung diseases) recruited in 30 randomly selected geographic areas of Italy. The study sample consisted of 709 key relatives of patients with a DSM-IV diagnosis of schizophrenia and 646 key relatives of patients with physical diseases. Each relative was asked to fill in the Family Problems Questionnaire (FPQ) and the Social Network Questionnaire (SNQ). In all selected pathologies, the consequences of caregiving most frequently reported as always present in the past 2 months were constraints in social activities, negative effects on family life, and a feeling of loss. Objective burden was higher in brain diseases, and subjective burden was higher in schizophrenia and brain diseases than in the other groups. Social support and help in emergencies concerning the patient were dramatically lower among relatives of patients with schizophrenia than among those of patients with physical diseases. In the schizophrenia group, both objective and subjective burden were significantly higher among relatives who reported lower support from their social network and professionals. The results of this study highlight the need to provide the families of those with long-term diseases with supportive interventions, including: (a) the management of relatives' psychological reactions to patient's illness; (b) the provision of information on the nature, course and outcome of patient's disease; (c) training for the relatives in the management of the patient's symptoms; and (d) the reinforcement of relatives' social networks, especially in the case of schizophrenia.

    2014-04-01

    Ischemic placental disease can have long-term maternal health implications. In this article, we discuss the three conditions of ischemic placental disease (preeclampsia, fetal growth restriction, and abruption placenta) and its associated long-term maternal morbidity. Retrospective observational studies comparing pregnancies complicated by ischemic placental disease to uncomplicated pregnancies suggest an increased long-term risk of hypertension, cardiovascular death, metabolic syndrome, and cerebrovascular disease. This association is much stronger in women who had an indicated-preterm delivery due to ischemic placental disease. It is important to adequately counsel women who are diagnosed with these conditions about their future health risks. Increased awareness of the potential health risks and multidisciplinary collaboration remains paramount to instituting the appropriate screening and preventative strategies (i.e., behavior modification) for affected women.

  16. Long-term Outcomes of Ventricular Tachycardia Ablation in Different Types of Structural Heart Disease

    2015-01-01

    Ventricular tachycardia (VT) often occurs in the setting of structural heart disease and can affect patients with ischaemic or nonischaemic cardiomyopathies. Implantable cardioverter-defibrillators (ICDs) provide mortality benefit and are therefore indicated for secondary prevention in patients with sustained VT, but they do not reduce arrhythmia burden. ICD shocks are associated with increased morbidity and mortality, and antiarrhythmic medications are often used to prevent recurrent episodes. Catheter ablation is an effective treatment option for patients with VT in the setting of structural heart disease and, when successful, can reduce the number of ICD shocks. However, whether VT ablation results in a mortality benefit remains unclear. We aim to review the long-term outcomes in patients with different types of structural heart disease treated with VT ablation. PMID:26835122

    The kidneys of long term dialysis patients frequently demonstrate multiple small acquired cysts and renal cell tumors on pathologic examination. The original kidneys of 30 long-term dialysis patients and six renal transplant patients were evaluated by computed tomography to determine the incidence of these abnormalities. Among dialysis patients, 43.3% had diffuse bilateral cysts, while 16.7% had occasional cysts (fewer than five per kidney), and 40% showed no renal cysts. Seven solid renal tumors were detected in four dialysis patients with renal cysts. Acquired cystic kidney disease tends to result in renal enlargement, is more common in patients who have been maintained on dialysis for prolonged periods, and may lead to spontaneous renal hemorrhage. The six transplant patients showed no evidence of renal cysts, and all had markedly shrunken kidneys. Acquired cystic disease and renal cell tumors in the original kidneys of dialysis patients may be due to biologically active substances that are not cleared effectively by dialysis but that are removed by normally functioning transplant kidneys.

    In t(8;21)(q22;q22) acute myeloid leukemia, the prognostic value of early minimal residual disease assessed with real-time quantitative polymerase chain reaction is the most important prognostic factor, but how long-term minimal residual disease monitoring may contribute to drive individual patient decisions remains poorly investigated. In the multicenter CBF-2006 study, a prospective monitoring of peripheral blood and bone marrow samples was performed every 3 months and every year, respectively, for 2 years following intensive chemotherapy in 94 patients in first complete remission. A complete molecular remission was defined as a (RUNX1-RUNX1T1/ABL1)×100 ≤ 0.001%. After the completion of consolidation therapy, a bone marrow complete molecular remission was observed in 30% of the patients, but was not predictive of subsequent relapse. Indeed, 8 patients (9%) presented a positive bone marrow minimal residual disease for up to 2 years of follow-up while still remaining in complete remission. Conversely, a peripheral blood complete molecular remission was statistically associated with a lower risk of relapse whatever the time-point considered after the completion of consolidation therapy. During the 2-year follow-up, the persistence of peripheral blood complete molecular remission was associated with a lower risk of relapse (4-year cumulative incidence, 8.2%), while molecular relapse confirmed on a subsequent peripheral blood sample predicted hematological relapse (4-year cumulative incidence, 86.9%) within a median time interval of 3.9 months. In t(8;21)(q22;q22) acute myeloid leukemia, minimal residual disease monitoring on peripheral blood every 3 months allows for the prediction of hematological relapse, and to identify patients who could potentially benefit from intervention therapy.

    Background Anti-glomerular basement membrane (GBM) antibody disease may lead to acute crescentic glomerulonephritis with poor renal prognosis. Current therapy favours plasma exchange (PE) for removal of pathogenic antibodies. Immunoadsorption (IAS) is superior to PE regarding efficiency of antibody-removal and safety. Apart from anecdotal data, there is no systemic analysis of the long-term effects of IAS on anti-GBM-disease and antibody kinetics. Objective To examine the long-term effect of high-frequency IAS combined with standard immunosuppression on patient and renal survival in patients with anti-GBM-disease and to quantify antibody removal and kinetics through IAS. Design Retrospective review of patients treated with IAS for anti-GBM-antibody disease confirmed by biopsy and/or anti-GBM-antibodies. Setting University Hospital of Vienna, Austria. Participants 10 patients with anti-GBM-disease treated with IAS. Measurements Patient and renal survival, renal histology, anti-GBM-antibodies. Results Anti-GBM-antibodies were reduced by the first 9 IAS treatments (mean number of 23) to negative levels in all patients. Renal survival was 40% at diagnosis, 70% after the end of IAS, 63% after one year and 50% at the end of observation (mean 84 months, range 9 to 186). Dialysis dependency was successfully reversed in three of six patients. Patient survival was 90% at the end of observation. Conclusion IAS efficiently eliminates anti-GBM-antibodies suggesting non-inferiority to PE with regard to renal and patient survival. Hence IAS should be considered as a valuable treatment option for anti-GBM-disease, especially in patients presenting with a high percentage of crescents and dialysis dependency due to an unusual high proportion of responders.

    Wilson's disease is an inherited disease of copper accumulation caused by a failure of biliary excretion of excess copper. Accumulated copper causes liver disease in these patients, and in perhaps two thirds of patients, it causes brain damage leading to clinical neurologic or psychiatric dysfunction. Maintenance treatment involves reversing the positive copper balance. The earliest approaches have used chelators, such as penicillamine or trientine, which increase the urinary excretion of copper. A more recent approach has used zinc, which blocks the absorption of copper and increases copper excretion in the stool. Because of the high level of endogenously secreted copper in alimentary secretions, the reabsorption of which is partially blocked by zinc therapy, zinc acts to remove accumulated copper from the body as well as prevent its reaccumulation. In the present article we present data on the long-term follow-up (up to 10 years) of maintenance zinc treatment of 141 patients with Wilson's disease. The data presented document that zinc is effective as a sole therapy in the long-term maintenance treatment of Wilson's disease and that it has a low toxicity. The results demonstrate the efficacy of zinc therapy in treating the presymptomatic patient from the beginning of therapy. We also present limited data on the use of zinc in the treatment of pregnant patients and children who have Wilson's disease; these data also indicate efficacy and low toxicity. The median follow-up period for the group as a whole is 4.8 years; for the presymptomatic patients it is 6.5 years; for the children it is 3.6 years.

    Purpose: To review long-term outcomes following postoperative radiotherapy (RT) for extremity soft tissue sarcoma (STS) and identify variables affecting the therapeutic ratio. Methods and Materials: Between 1970 and 2008, 173 patients with localized extremity STS were treated with postoperative radiation. No patients received prior irradiation. Sixteen percent of tumors had recurred after initial surgery alone; 89% of tumors were high grade. The median patient age was 57 years (range, 18-86 years). Sixty-one percent underwent >1 surgery before RT in an attempt to achieve wide negative margins. Final margin status was negative in 70% and marginal or microscopically positive in 30%. The median time between final surgery and start of RT was 40 days. The median RT dose was 65 Gy (range, 49-74 Gy). The median follow-up for all patients was 10.4 years and 13.2 years among survivors. Results: At 10 years, local control (LC), cause-specific survival (CSS), and overall survival (OS) rates were 87%, 80%, and 70%, respectively, with 89% of local failures occurring within 3 years after treatment. On multivariate analysis, age >55 years (82% vs 93%, P<.05) and recurrent presentation (67% vs 91%, P<.05) were associated with inferior 10-year LC. The LC according to final margin status was 90% for wide negative margins vs 79% for marginal/microscopically positive margins (P=.08). Age >55 years and local recurrence were associated with inferior CSS and OS on multivariate analysis. Twelve percent of patients experienced grade 3+ toxicity; 12 of these occurred in patients with tumors of the proximal lower extremity, with the most common toxicity of pathologic fracture occurring in 6.3%. Conclusions: This large single-institution series confirms that postoperative RT for STS of the extremities provides good long-term disease control with acceptable toxicity. Our experience supports recurrent presentation and older age as adverse prognostic factors for LC.

    The purpose of the present study was to determine whether any of the clinical parameters recorded during an initial periodontal examination would relate to the course of periodontal cases maintained for long periods of time. Based on available documentation, cases which had a downhill course were assembled from a population previously studied. In addition, long-term cases currently under maintenance care were drawn from our private practice. On average, the patients had been under care for 23 years. The study population was heavily weighted toward downhill cases to better compare these cases with those usually found in periodontal practice. Positive statistical correlations were found between the amount of subgingival calculus and the degree of gingival inflammation at initial examination. Disease severity initially was positively correlated to long-term course of disease. The amount of subgingival calculus did not relate to the long-term result. There was a strong correlation between inflammatory gingival hyperplasia initially and good long-term maintenance. The results suggest that, in combination, initial characteristics of periodontal cases coupled with long-term results of treatment may aid in further subclassifying the periodontal diseases.

    Cushing disease is caused by excessive adrenocorticotropic hormone (ACTH) production by the pituitary adenoma. Transsphenoidal surgery is its first-line treatment. The incidence of Cushing disease in children and adolescents is so rare that long-term prognoses have yet to be made in most cases. We followed-up on a 16-year-old male Cushing disease patient who presented with rapid weight gain and growth retardation. The laboratory findings showed increased 24-hour urine free cortisol and lack of overnight cortisol suppression by low-dose dexamethasone test. The serum cortisol and 24-hour urine free cortisol, by high-dose dexamethasone test, also showed a lack of suppression, and a bilateral inferior petrosal sinus sampling suggested lateralization of ACTH secretion from the right-side pituitary gland. However, after a right hemihypophysectomy by the transsphenoidal approach, the 24-hour urine free cortisol levels were persistently high. Thus the patient underwent a total hypophysectomy, since which time he has been treated with hydrocortisone, levothyroxine, recombinant human growth hormone, and testosterone enanthate. Intravenous bisphosphonate for osteoporosis had been administered for three years. At his current age of 26 years, his final height had attained the target level range; his bone mineral density was normal, and his pubic hair was Tanner stage 4. This report describes the long-term treatment course of a Cushing disease patient according to growth profile, pubertal status, and responses to hormone replacement therapy. The clinical results serve to emphasize the importance of growth optimization, puberty, and bone health in the treatment management of Cushing disease patients who have undergone transsphenoidal surgery.

    Purpose: To analyze retrospectively the long-term results of external beam radiotherapy (RT) with or without intraluminal brachytherapy (ILBT) for patients with Stage I esophageal cancer. Methods and Materials: A total of 34 patients with esophageal squamous cell carcinoma, clinically diagnosed as having Stage I disease, were treated with definitive RT, with or without ILBT. The median age was 69 years. Seven patients were treated with external beam RT alone (median, 64 Gy), and 27 were treated with external beam RT (median, 52 Gy) plus ILBT (8-12 Gy in two to three fractions). Results: The 5-year overall survival, local relapse-free survival, and cause-specific survival rate was 58.9%, 68.4%, and 80.0%, respectively, with a median follow-up of 61 months. Of 9 patients with local recurrence after initial therapy, 7 were successfully treated, and the 5-year cumulative rate of esophagectomy was 19.6%. The 2-year local relapse-free rate for patients with and without ILBT was 79.1% and 53.6%, respectively. Conclusion: Although local recurrence was frequent within 2 years, the disease-specific survival rate was high owing to effective salvage therapy. Definitive RT is a reasonable treatment option for highly comorbid and elderly patients with Stage I esophageal cancer. The role of ILBT needs to be clarified.

    The results of 144 previously untreated cases of primary Ewing's sarcoma of bone are reported with a minimum follow-up of 5 years. This series was treated between 1972 and 1982 at Istituto Ortopedico Rizzoli with a combined therapy. The local control of the disease consisted of amputation (ten cases), resection followed by radiation therapy (35-45 Gy) (48 cases) and radiation therapy alone (40-60 Gy) (86 cases). Adjuvant chemotherapy, rigorously standardized, was performed according two different protocols: the first (85 cases treated in the period 1972-1978) consisted of vincristine (VCR) Adriamycin (doxorubicin) (ADM), and cyclophosphamide (EDX); the second (59 cases treated in the period 1979-1982) of VCR, ADM, EDX and dactinomycin (DACT). At a follow-up of 5 to 16 years (median, 9), 59 patients (41%) are continuously disease-free (CDF), 81 (56%) developed metastatic disease and/or local recurrence, and four (3%) had a second malignancy. Three factors seem to be correlated to prognosis: the site of the initial lesion (only 23% of the pelvic lesions are represented in the CDF group versus 46% of the other locations); the chemotherapy protocol (32% of the cases in the first protocol are CDF versus 54% in the second); the type of local treatment (60% of the patients treated with amputation or resection plus radiotherapy versus 28% of those treated with radiation therapy alone are CDF). A local recurrence was observed in 24% of the patients (8% in the group locally treated with surgery or surgery plus radiation therapy versus 36% in the group treated with radiation therapy alone). These data suggest that even though adjuvant chemotherapy can improve the long-term results in localized Ewing's sarcoma patients, this disease still represents, in a high percentage of cases, a lethal process whose final prognosis widely depends on the local control of the lesion.

    The tooth root growth impairment that resulted from 35 to 37 Gy mantle port radiation in 47 long-term survivors of childhood Hodgkin's disease was quantified and related to specific age groups and categories of teeth. Root measurements of the mandibular permanent canines, first and second premolars, and first and second molars were made from sequential panoramic radiographs taken at the time of radiation therapy and after the closure of root apexes. The severity of root growth impairment was greatest in patients who received radiation during the early stages of odontogenesis. With later stages of odontogenesis, and as the age increased at the time of treatment, less impairment occurred. The potential difficulties of using repeated panoramic radiographs to assess tooth lengths in longitudinal studies also were discussed.

    Diffuse nasal polyposis remains a challenge despite recent improvements in endonasal surgery. The purpose of this study is to evaluate the results after a radical complete sphenoethmoidectomy with peroperative and postoperative frontal irrigation in cases of diffuse nasal polyposis. In this prospective study, we include 50 consecutive patients with diffuse nasal polyposis suffering from nasal obstruction, anosmia, and other symptoms of chronic sinusitis. All patients were refractory to medical therapy. In each patient an endoscopic complete sphenoethmoidectomy including total excision of all diseased ethmoid mucosa was performed. Preoperative and postoperative frontal irrigation was performed systematically. The patients were followed closely with serial endoscopic examination, and CT scanning was performed between 2 and 3 years after surgery. There were no complications. Thirty-nine of the 50 patients regained satisfactory olfaction. Partial nasal obstruction persisted in four of the 50 patients. Endoscopically, polyp recurrence was noted in 3% of posterior ethmoids, 23% of anterior ethmoids, and 50% of frontal recesses. We conclude that in cases of refractory and extensive nasal polyposis, a total sphenoethmoidectomy with perioperative frontal irrigation followed by long-term postoperative topical steroid therapy provides excellent improvement or cure with safety and reliability.

    The aim of the study was to evaluate the long-term results after surgery for acquired cholesteatoma in children and to contribute to the search for predictors of recurrence. During a 15-year period, 114 children underwent surgery. The patients were re-evaluated with a median observation time of 5.8 years. At the last re-evaluation 85 per cent of the ears were dry with an intact drum. Recurrence of cholesteatoma developed in 27 ears. The cumulated total recurrence rate was 24 per cent using the incidence rate calculation, applying Kaplan-Meier survival analysis the corresponding recurrence was 33 per cent. Recurrent disease occurred significantly more frequently in children younger than eight years, with a negative pre-operative Valsalva, with ossicular resorption and with large cholesteatomas. In conclusion, young children with poor Eustachian tube function and a large cholesteatoma with erosion of the ossicular chain, are at special risk of recurrence and should be observed for several years after surgery.

  12. Long term enzyme replacement therapy for Fabry disease: effectiveness on kidney, heart and brain

    PubMed Central

    2013-01-01

    Background Fabry disease is an X-linked lysosomal storage disorder caused by α-galactosidase A deficiency leading to renal, cardiac, cerebrovascular disease and premature death. Treatment with α-galactosidase A (enzyme replacement therapy, ERT) stabilises disease in some patients, but long term effectiveness is unclear. Methods Renal, cardiac, and cerebral outcomes were prospectively studied in males and females with Fabry disease treated with ERT. Additionally, the occurrence of major cardiac events, stroke, end-stage renal disease and death was compared to a natural history (NH) cohort meeting treatment criteria. Results Of 75 patients on ERT (median treatment duration 5.2 years, range 0.05-11.0), prospective follow-up was available for 57 adult patients (30 males) and 6 adolescents. Renal function declined in males (-3.4 ml/min/1.73 m2 per year, SE 0.2; p < 0.001) despite ERT, but followed the normal course in females (-0.8 ml/min/1.73 m2 per year, SE 0.3; p = 0.001). Cardiac mass increased during ERT in males (+ 1.2 gram/m2.7, SE 0.3; p < 0.001), but remained stable in females (-0.3 gram/m2.7 per year, SE 0.4; p = 0.52). ERT did not prevent the occurrence of cerebral white matter lesions. Comparison of ERT treated to untreated patients revealed that the odds to develop a first complication increased with age (OR 1.05 (95% CI: 1.0-1.1) per year, p = 0.012). For development of a first or second complication the odds declined with longer treatment duration (OR 0.81 (95% CI: 0.68-0.96) per year of ERT, p = 0.015;OR 0.52 (0.31-0.88), p = 0.014 respectively). Conclusions Long term ERT does not prevent disease progression, but the risk of developing a first or second complication declines with increasing treatment duration. ERT in advanced Fabry disease seems of doubtful benefit. PMID:23531228

    Background: Effective medical and surgical management of pediatric congenital heart disease (CHD) to reduce long-term adverse neurodevelopmental outcomes is an important clinical objective in primary and specialty health care. We identify clinical predictors associated with an increased risk of 6 long-term neurodevelopmental outcomes in children with CHD compared to the general pediatric Medicaid population. Method: South Carolina’s retrospective, 15-year Medicaid data set (January 1, 1996–December 31, 2010) for 19,947 patients aged ≤ 17 years diagnosed with ≥ 1 CHD lesions (on the basis of International Classification of Diseases, Ninth Revision, Clinical Modification codes) were compared to 19,948 patients without CHD matched on age at entry into and duration in Medicaid using logistic and Cox proportional hazards regression. Results: The CHD cohort was significantly less likely to have incident neurologic or psychiatric disorders, mental retardation, developmental delays, or inattention/hyperactivity (adjusted odds ratios [ORs] = 0.34, 0.56, 0.03, 0.01, 0.004, respectively) but was more likely to have incident seizures (OR = 2.00) compared to controls. Exposure to both cardiac and noncardiac surgical intervention was associated with a significantly increased risk of developing neurologic or psychiatric disorders, mental retardation, developmental delays, or inattention/hyperactivity (cardiac ORs = 1.66, 2.00, 1.67, 1.43, 1.76, respectively) (noncardiac ORs = 2.25, 1.59, 1.48, 1.29, 1.36, 2.46, respectively). Any documented hypoxemia was associated with a significantly increased risk of developing 5 of the neurodevelopmental conditions (neurologic OR = 4.52, psychiatric OR = 1.60, mental retardation OR = 2.90, developmental delay OR = 2.12, seizures OR = 4.23). Conclusion: Practitioners should maintain vigilant surveillance of all CHD patients, especially those exposed to surgical procedures or experiencing hypoxemia, to identify any neurodevelopmental

    Severe obstructive sleep apnea (OSAS) is most often accompanied by metabolic syndrome, obesity, diabetes and coronary disease. In its most severe form, it is a life-threatening condition, requiring active and immediate help. Nasal continuous positive airway pressure (CPAP) is the most efficient nonsurgical treatment for patients with OSAS. However, for anatomical, disease-related and subjective reasons, many patients cannot accept this treatment. A permanent tracheostomy may be one alternative in such patients who, in addition, often suffer from extreme obesity and severe heart disease. In this paper, we describe the long-term follow-up results of 7 patients suffering from OSAS and treated with permanent tracheostomy. All the patients (5 men, 2 women) were diagnosed using the static charge sensitive bed method and night-time oximetry for sleep analysis. The mean body mass index (BMI) of the patients ranged from 34 to 60 and the age from 41 to 64 years. All the patients had severe OSAS and long periods of low oxygen saturation (SaO2) levels. Six patients had a CPAP trial before tracheostomy. Only 2 patients tolerated the trial but, despite the continuous use of CPAP, they were nonresponders. Permanent tracheostomy was done according to normal routine in each patient. After primary healing of 2 days, they used silver cannulae, which also allowed them to speak. The patients were evaluated every year after the tracheostomy. After some practical difficulties including proper maintenance of the cannula, all the patients quickly learned the correct management. In postoperative sleep studies, nadir SaO2 levels had improved significantly, obstructive apneas had disappeared and the subjective quality of life had improved. No marked changes in BMI were found.

    AIM: To evaluate the efficacy and long-term outcome of infliximab combined with surgery to treat perianal fistulizing Crohn’s disease (CD). METHODS: The work was performed as a prospective study. All patients received infliximab combined with surgery to treat perianal fistulizing CD, which was followed by an immunosuppressive agent as maintenance therapy. RESULTS: A total of 28 patients with perianal fistulizing CD were included. At week 30, 89.3% (25/28) of the patients were clinically cured with an average healing time of 31.4 d. The CD activity index decreased to 70.07 ± 77.54 from 205.47 ± 111.13 (P < 0.01) after infliximab treatment. The perianal CD activity index was decreased to 0.93 ± 2.08 from 8.54 ± 4.89 (P < 0.01). C-reactive protein, erythrocyte sedimentation rate, platelets, and neutrophils all decreased significantly compared with the pretreatment levels (P < 0.01). Magnetic resonance imaging results for 16 patients after therapy showed that one patient had a persistent presacral-rectal fistula and another still had a cavity without clinical symptoms at follow-up. After a median follow-up of 26.4 mo (range: 14-41 mo), 96.4% (27/28) of the patients had a clinical cure. CONCLUSION: Infliximab combined with surgery is effective and safe in the treatment of perianal fistulizing CD, and this treatment was associated with better long-term outcomes. PMID:25741157

    Left ventricular reconstruction is advocated as a surgical option for patients with severe congestive heart failure. Despite initial enthusiasm for this procedure, reports of long-term results are sparse. Herein, we describe a particularly gratifying case of left ventricular reconstruction in a 43-year-old man, who continues to have excellent left ventricular function 10 years postoperatively. This approach may be a reasonable alternative to cardiac transplantation in patients who lack other treatment options.

Methods and Materials: Twenty-two patients with unresectable (17 patients) or residual (5 patients) nonmetastatic extrahepatic bile tumors received external beam radiation therapy (39.6-50.4 Gy) between 1991 and 1997. In 21 patients, 5-fluorouracil (96-h continuous infusion, Days 1-4, 1,000 mg/m{sup 2}/day) was administered. Twelve patients received a boost of intraluminal brachytherapy with {sup 192}Ir wires (30-50 Gy) 1 cm from the source axis. Results: During external beam radiotherapy, 10 patients (45.4%) developed Grade 1 to 2 gastrointestinal toxicity. In patients with unresectable tumor who could be evaluated, the clinical response was 28.6% (4 of 14). Two patients showed complete response. In all 22 patients, median durations of local control, disease-free survival, and overall survival were 44.5 months, 16.3 months, and 23.0 months, respectively. Two patients who received external beam radiation therapy and intraluminal brachytherapy developed late duodenal ulceration. In patients with unresectable tumors, median survival was 13.0 months and 22.0 months in those treated with and without brachytherapy, with 16.7% and no 5-year survival, respectively (p = 0.607). Overall 5-year survival was 18.0%: 40% and 11.7% in patients treated with partial resection and in those with unresectable tumor, respectively (p = 0.135). Conclusion: This study confirmed the role of concurrent chemoradiation in advanced biliary carcinoma; the role of intraluminal brachytherapy boost remains to be further analyzed in larger clinical trials.

    Survivors of sepsis often experience long-term cognitive and functional decline. Previous studies utilizing lipopolysaccharide injection and cecal ligation and puncture in rodent models of sepsis have demonstrated changes in depressive-like behavior and learning and memory after sepsis, as well as evidence of myeloid inflammation and cytokine expression in the brain, but the long-term course of neuroinflammation after sepsis remains unclear. Here, we utilize cecal ligation and puncture with greater than 80% survival as a model of sepsis. We found that sepsis survivor mice demonstrate deficits in extinction of conditioned fear, but no acquisition of fear conditioning, nearly two months after sepsis. These cognitive changes occur in the absence of neuronal loss or changes in synaptic density in the hippocampus. Sepsis also resulted in infiltration of monocytes and neutrophils into the CNS at least two weeks after sepsis in a CCR2 independent manner. Cellular inflammation is accompanied by long-term expression of pro-inflammatory cytokine and chemokine genes, including TNFα and CCR2 ligands, in whole brain homogenates. Gene expression analysis of microglia revealed that while microglia do express anti-microbial genes and damage-associated molecular pattern molecules of the S100A family of genes at least 2 weeks after sepsis, they do not express the cytokines observed in whole brain homogenates. Our results indicate that in a naturalistic model of infection, sepsis results in long-term neuroinflammation, and that this sustained inflammation is likely due to interactions among multiple cell types, including resident microglia and peripherally derived myeloid cells.

    Bilateral subthalamic nucleus stimulation (STN-DBS) is used to improve parkinsonian symptoms and attenuate levodopa-induced motor complications. In some patients, such clinical improvement allows antiparkinsonian medication (ApMed) withdrawal. We show the clinical outcome at the long-term follow-up of patients with advanced Parkinson's disease (PD) in which STN-DBS was used in monotherapy, and compare the clinical results of patients without medication with those obtained in parkinsonian patients in which ApMed were reduced but could not be totally displaced after surgery. We analyzed clinical outcome of ten patients with PD in which all ApMed was withdrawn after bilateral subthalamic stimulation and 16 parkinsonian patients still taking antiparkinsonian medication after surgery. After 1.5 years, STN-DBS monotherapy produced UPDRS motor scores similar to those observed in the on-drug condition before surgery without the inconvenience of motor fluctuations and dyskinesias. No significant differences were seen in most of clinical outcome measures when comparing patients still taking ApMed with patients in STN-DBS monotherapy but a few patients still taking ApMed presented mild dyskinesias and motor fluctuations and patients with STN-DBS monotherapy did not. STN-DBS is useful in the treatment of advanced PD and in some patients it is possible to maintain this therapy alone in the long term. The therapeutic effect of STN-DBS on motor signs can be equipotent to that of levodopa with the additional benefit of avoiding motor fluctuations and dyskinesias.

    Parkinson disease (PD) is associated with a clinical course of variable duration, severity, and a combination of motor and non-motor features. Recent PD research has focused primarily on etiology rather than clinical progression and long-term outcomes. For the PD patient, caregivers, and clinicians, information on expected clinical progression and long-term outcomes is of great importance. Today, it remains largely unknown what factors influence long-term clinical progression and outcomes in PD; recent data indicate that the factors that increase the risk to develop PD differ, at least partly, from those that accelerate clinical progression and lead to worse outcomes. Prospective studies will be required to identify factors that influence progression and outcome. We suggest that data for such studies is collected during routine office visits in order to guarantee high external validity of such research. We report here the results of a consensus meeting of international movement disorder experts from the Genetic Epidemiology of Parkinson's Disease (GEO-PD) consortium, who convened to define which long-term outcomes are of interest to patients, caregivers and clinicians, and what is presently known about environmental or genetic factors influencing clinical progression or long-term outcomes in PD. We propose a panel of rating scales that collects a significant amount of phenotypic information, can be performed in the routine office visit and allows international standardization. Research into the progression and long-term outcomes of PD aims at providing individual prognostic information early, adapting treatment choices, and taking specific measures to provide care optimized to the individual patient's needs.

    Purpose. To evaluate the technical and clinical success, safety and long term results of percutaneous transluminal angioplasty/self-expandable nitinol stent placement of infrarenal abdominal aorta focal lesions. Materials and Methods. Eighteen patients underwent PTA of focal atherosclerotic occlusive disease of distal abdominal aorta. Two symptomatic occlusions and 16 stenoses in 10 male and 8 female patients (mean age 68.2 years) were treated with primary self-expandable nitinol stent placement. Results. Primary self-expandable nitinol stent placement was technically successful in all 18 procedures; clinical success was achieved in 100% of patients. No complications associated with the procedure occurred. During the 49.4 months of mean follow up (range 3-96, 4 months) all treated aortic segments remained patent. Conclusions. Endovascular treatment (primary self-expandable nitinol stent placement) of focal atherosclerotic lesions of distal abdominal aorta is a safe method with excellent primary technical and clinical success rates and favourable Long term results.

    ABSTRACT Background: Stapled hemorrhoidopexy is associated with less postoperative pain and faster recovery. However, it may be associated with a greater risk of symptomatic recurrence. We hypothesized that undertaking a limited surgical excision of hemorrhoid disease after stapling may be a valid approach for selected patients. Aim: To compare long-term results after stapled hemorrhoidopexy with and without complementation with closed excisional technique. Method: In a retrospective uni-institutional cohort study, sixty-five (29 men) patients underwent stapled hemorrhoidopexy and 21 (13 men) underwent stapled hemorrhoidopexy with excision. The same surgeons operated on all cases. Patients underwent stapled hemorrhoidectomy associated with excisional surgery if symptoms attributable to external hemorrhoid piles were observed preoperatively, or if residual prolapse or bulky external disease was observed after the firing of the stapler. A closed excisional diathermy hemorrhoidectomy without vascular ligation was utilized in all complemented cases. All clinical variables were obtained from a questionnaire evaluation obtained through e-mail, telephone interview, or office follow-up. Results: The median duration of postoperative follow-up was 48.5 (6-40) months. Patients with grades 3 and 4 hemorrhoid disease were operated on more frequently using stapled hemorrhoidopexy complemented with excisional technique (95.2% vs. 55.4%, p=0.001). Regarding respectively stapled hemorrhoidopexy and stapled hemorrhoidopexy complemented with excision, there was no difference between the techniques in relation to symptom recurrence (43% and 33%, p=0.45) and median interval between surgery and symptom recurrence (30 (8-84) and 38.8 (8-65) months, p=0.80). Eight (12.3%) patients were re-operated after stapled hemorrhoidopexy and 2 (9.6%), after hemorrhoidopexy with excision (p=0.78). Patient distribution in both groups according to the degree of postoperative satisfaction was similar (p

    Objective The purpose of this study was to evaluate long-term follow-up radiologic/clinical outcomes of patients who underwent anterior cervical discectomy and inter-body fusion (ACDF) with stand-alone cages (SAC) in a single academic institution. Methods Total 99 patients who underwent ACDF with SAC between February 2004 and December 2012 were evaluated retrospectively. A total of 131 segments were enrolled in this study. Basic demographic information, radiographic [segmental subsidence rate, fusion rate, C2–7 global angle, and segmental angle changes)/clinical outcomes (by Odom's criteria and visual analog score (VAS)] and complications were evaluated to determine the long-term outcomes. Results The majority were males (55 vs. 44) with average age of 53.2. Mean follow-up period was 62.9 months. The segmental subsidence rate was 53.4% and fusion rate was 73.3%. In the subsidence group, anterior intervertebral height (AIH) had more tendency of subsiding than middle or posterior intervertebral height (p=0.01). The segmental angle led kyphotic change related to the subsidence of the AIH. Adjacent segmental disease was occurred in 18 (18.2%) patients. Total 6 (6%) reoperations were performed at the index level. There was no statistical significance between clinical and radiological outcomes. But, overall long-term clinical outcome by Odom's criteria was unsatisfactory (64.64%). The neck and arm VAS score were increased by over time. Conclusion Long-term outcomes of ACDF with SAC group were acceptable but not satisfactory. For optimal decision making, more additional comparative long-term outcome data is needed between ACDF with SAC and ACDF with plating. PMID:27446521

    In the 1970s, high failure rates of cemented acetabular components, especially in young patients, in the middle- and long-term prompted a search for alternatives. The Mecring was one of the most popular first generation uncemented, threaded cups widely used in the 1980s for arthroplasty of the hip. First generation threaded cups commonly had smooth surface treatment and showed unacceptably high failure rates in the mid-term. In a consecutive series of 209 patients, 221 threaded uncemented acetabular cups with smooth surface treatment (Mecring) had been implanted in combination with one type of uncemented stem. Patients were followed up clinically and radiographically. The mean time of follow-up was 17 (range 15–20) years. In 91 (41%) hips the acetabular component had been revised or was awaiting revision: two hips for infection and 84 (38%) for aseptic loosening. Five hips were awaiting revision. The survival rate for all revisions including hips awaiting revision was 49% (95% CI: 41–57%) at 17 years. These results support the view that smooth, threaded acetabular components do not provide satisfactory long-term fixation and should be abandoned. Patients with these components must be closely monitored as the failure rate remains high in the long-term. PMID:19629481

    We present a long term followup (13 years) of spinal hydatid disease with multiple recurrences and intradural dissemination of the disease at the last followup. Intradural extension of the disease in our case was supposedly through the dural rent which has not been reported in English literature. An early followup of the same case has been reported previously by the authors. A 53 year-old female came with progressive left leg pain and difficulty in walking since 2 months. On examination, she had grade four power of ankle and digit dorsiflexors (L4 and L5 myotomes) on the left side (Medical Research Council grade). There was no sensory loss, no myelopathy and sphincters were intact. Plain radiographs showed consolidation at D10-D11 (old operated levels) with stable anterior column and there were no implant related problems. Magnetic resonance imaging showed a cystic lesion at L3-L4, signal intensity same as of cerebrospinal fluid in T2 and T1, displacing the cauda equina roots. The proximal extent of the lesion could not be identified because of artifacts from previous stainless steel instrumentation. Computed tomography myelogram showed complete block at L3-L4 junction with “meniscus sign”. This is the longest followup of hydatid disease of the spine that has ever been reported. Hydatid disease should always be included in the differential diagnosis of destructive or infectious lesions of the spine. Aggressive radical resection whenever possible and chemotherapy is the key to good results. Recurrence is known to occur even after that. Disease can have long remission periods. Possibility of intradural dissemination through dural injury is highly likely. Hence, it should always be repaired whenever possible. PMID:25298565

    Immunosuppression after measles is known to predispose people to opportunistic infections for a period of several weeks to months. Using population-level data, we show that measles has a more prolonged effect on host resistance, extending over 2 to 3 years. We find that nonmeasles infectious disease mortality in high-income countries is tightly coupled to measles incidence at this lag, in both the pre- and post-vaccine eras. We conclude that long-term immunologic sequelae of measles drive interannual fluctuations in nonmeasles deaths. This is consistent with recent experimental work that attributes the immunosuppressive effects of measles to depletion of B and T lymphocytes. Our data provide an explanation for the long-term benefits of measles vaccination in preventing all-cause infectious disease. By preventing measles-associated immune memory loss, vaccination protects polymicrobial herd immunity. PMID:25954009

  10. Control of neglected tropical diseases needs a long-term commitment

    2010-01-01

    Background Neglected tropical diseases are widespread, particularly in sub-Saharan Africa, affecting over 2 billion individuals. Control of these diseases has gathered pace in recent years, with increased levels of funding from a number of governmental or non-governmental donors. Focus has currently been on five major 'tool-ready' neglected tropical diseases (lymphatic filariasis, onchocerciasis, schistosomiasis, soil-transmitted helminthiasis and trachoma), using a package of integrated drug delivery according to the World Health Organization guidelines for preventive chemotherapy. Discussion Success in controlling these neglected tropical diseases has been achieved in a number of countries in recent history. Experience from these successes suggests that long-term sustainable control of these diseases requires: (1) a long-term commitment from a wider range of donors and from governments of endemic countries; (2) close partnerships of donors, World Health Organization, pharmaceutical industries, governments of endemic countries, communities, and non-governmental developmental organisations; (3) concerted action from more donor countries to provide the necessary funds, and from the endemic countries to work together to prevent cross-border disease transmission; (4) comprehensive control measures for certain diseases; and (5) strengthened primary healthcare systems as platforms for the national control programmes and capacity building through implementation of the programmes. Conclusions The current level of funding for the control of neglected tropical diseases has never been seen before, but it is still not enough to scale up to the 2 billion people in all endemic countries. While more donors are sought, the stakeholders must work in a coordinated and harmonised way to identify the priority areas and the best delivery approaches to use the current funds to the maximum effect.

    OBJECTIVES: To evaluate the safety and long-term efficacy of computed tomography-guided percutaneous ethanol ablation for benign primary and secondary hyperfunctioning adrenal disorders. METHOD: We retrospectively evaluated the long-term results of nine patients treated with computed tomography-guided percutaneous ethanol ablation: eight subjects who presented with primary adrenal disorders, such as pheochromocytoma, primary macronodular adrenal hyperplasia and aldosterone-producing adenoma, and one subject with Cushing disease refractory to conventional treatment. Eleven sessions were performed for the nine patients. The patient data were reviewed for the clinical outcome and procedure-related complications over ten years. RESULTS: Patients with aldosterone-producing adenoma had clinical improvement: symptoms recurred in one case 96 months after ethanol ablation, and the other patient was still in remission 110 months later. All patients with pheochromocytoma had clinical improvement but were eventually submitted to surgery for complete remission. No significant clinical improvement was seen in patients with hypercortisolism due to primary macronodular adrenal hyperplasia or Cushing disease. Major complications were seen in five of the eleven procedures and included cardiovascular instability and myocardial infarction. Minor complications attributed to sedation were seen in two patients. CONCLUSION: Computed tomography-guided ethanol ablation does not appear to be suitable for the long-term treatment of hyperfunctioning adrenal disorders and is not without risks. PMID:27759849

    Hyperuricemia is common in chronic kidney disease (CKD), but data regarding the relationship between serum uric acid levels and the long-term outcomes of CKD patients have been limited. The present study evaluated the associations between baseline serum uric acid levels with mortality and end-stage renal disease (ESRD). The subjects of this study were 551 stage 2-4 CKD patients. Cox proportional hazards models were used to evaluate the relationship between serum uric acid tertiles and all-cause mortality, cardiovascular disease (CVD) mortality, 50 % reduction in estimated glomerular filtration rate (eGFR), and development of ESRD, initially without adjustment, and then after adjusting for several groups of covariates. The mean age of the study subjects was 58.5 years, 59.3 % were men, and 10.0 % had diabetes. The mean eGFR was 42.02 ± 18.52 ml/min/1.73 m(2). In all subjects, the mean serum uric acid level was 6.57 ± 1.35 mg/dl, and 52.2 % of study subjects were on hypouricemic therapy (allopurinol; 48.3 %) at baseline. Thirty-one patients (6.1 %) died during a follow-up period of approximately 6 years. There was no significant association between serum uric acid level and all-cause mortality, CVD mortality, development of ESRD and 50 % reduction in eGFR in the unadjusted Cox models. In the adjusted models, hyperuricemia was found to be associated with all-cause mortality and CVD mortality after adjustment with CVD risk factors, kidney disease factors, and allopurinol, but not associated with development of ESRD and 50 % reduction in eGFR. The results of this study showed that hyperuricemia but not serum uric acid levels were associated with all-cause mortality, CVD mortality after adjustments with CVD risk factors, kidney disease factors, and allopurinol in stage 2-4 CKD patients.

    Study Design Prospective study. Purpose The aim of the study was to present long-term results from a 10-year follow-up after endoscopic lumbar discectomy (ELD) by "Destandau's technique". Overview of Literature Endoscopic disc surgery by Destandau's technique using ENDOSPINE Karl Storz system is a relatively new technique. It was introduced in 1993. It has been gaining popularity among the spine surgeons, as it is attractive for small skin incision and allows a gentle and excellent tissue dissection with excellent visualization. Many authors have published results of their own studies; however, in all these studies the long-term follow up of the patients has not been emphasized. Methods A total of 21 patients selected on basis of strict inclusion criteria's underwent ELD from November 2004 to March 2005. Surgery outcome was assessed by using "Prolo's Anatomic-Functional-Economic Rating System" (1986). Patients were followed up to 10 years. In addtion, we compared the results of our study with other studies. Results Outcomes were excellent in 17 patients (80.95%), good in 3 (14.28%) and fair in 1 (4.78%), with no patients having a poor result. In our study, 19 patients (90.47%) were able to resume their previous works/jobs, and only 2 (9.52%) needed to change their jobs for lighter work. No patient retired from his or her previous daily routine following the operation. Conclusions The initial and long-term results are very good for endoscopic lumbar discectomy by Destandau's technique. In properly selected patients it is a safe and minimally invasive technique, and we recommend ELD in properly selected patients. PMID:27114770

    For the first 30 years after repatriation, former American prisoners of war (POWs) of World War II and the Korean Conflict had lower death rates for heart disease and stroke than non-POW veteran controls and the U.S. population, but subsequent morbidity data suggested that this survival advantage may have disappeared. We used U.S. federal records to obtain death data through 1996 and used proportional hazards analysis to compare the mortality experience of POWs and controls. POWs aged 75 years and older showed a significantly higher risk of heart disease deaths than controls (hazard ratio = 1.25; 95% confidence interval, 1.01-1.56), and their stroke mortality was also increased, although not significantly (hazard ratio = 1.13; 95% confidence interval, 0.66-1.91). These results suggest that circulatory disease sequelae of serious, acute malnutrition and the stresses associated with imprisonment may not appear until after many decades. PMID:11569446

    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 <10 kg, previous exposure to Cytomegalovirus, donor-recipient sex and weight relations, autoimmune disease as indication for transplantion, previous Kasai's surgery, use of reduced liver grafts, chronic or acute rejection occurrence) and treatment was evaluated. Before PTC, fever was observed in 46%, biliary dilation in 23%, increased bilirubin in 57%, and increased gamma-glutamyltransferase (GGT) in 100% of patients. In the group with BAS, 24 of 35 (69%) patients had histopathologic findings of cholestasis as did 9 of 19 (47%) patients in the group with normal PTC. Of the 35 patients, 23 (65.7%) needed 1 (group I), 7 needed 2 (group II), 4 needed 3 (group III), and 1 needed 4 treatment sessions (group IV). The best results were observed after 1 treatment session, and the mean duration of catheter placement and replacement

    Background The impact of polyvascular disease (peripheral arterial disease [PAD] and/or cerebrovascular disease [CVD]) on long-term cardiovascular outcomes among older patients with acute myocardial infarction (MI) has not been well studied. Methods Non–ST-elevation MI (NSTEMI) patients aged ≥65 years from the CRUSADE registry who survived to hospital discharge were linked to longitudinal data from the Centers for Medicare and Medicaid Services (n=34,205). All patients were presumed to have coronary artery disease (CAD) and were classified into 4 groups: 10.7% had prior CVD (CAD+CVD group); 11.5% had prior PAD (CAD+PAD); 3.1% had prior PAD and CVD (CAD+PAD+CVD); and 74.7% had no polyvascular disease (CAD alone). Cox proportional hazard modeling was used to examine the hazard of long-term mortality and the composite of death, readmission for MI, or readmission for stroke (median follow-up 35 months, IQR 17–49) among the 4 groups. Results Compared with the CAD-alone group, patients with polyvascular disease had a greater comorbidity burden, were less likely to undergo revascularization, and less often received recommended discharge interventions. Three-year mortality rates increased with a greater number of arterial beds involved: 33% for CAD alone, 49% for CAD+PAD, 52% for CAD+CVD, and 59% for CAD+PAD+CVD. Relative to the CAD-alone group, patients with all 3 arterial beds involved had the highest risk of long-term mortality (adjusted HR [95% CI]: 1.49 [1.38–1.61], with a lower risk for those with CAD+CVD, 1.38 [1.31–1.44], and those with CAD+PAD, 1.29 [1.23–1.35]). Similarly, the adjusted risk of long-term composite ischemic events was highest among the CAD+PAD+CVD group. Conclusions Older NSTEMI patients with polyvascular disease have substantially higher long-term risk, such that the 3-year mortality rate is >50%. Future studies targeting greater adherance to secondary prevention strategies and novel therapies are needed to help reduce long-term

    2014-01-01

    Though the symptoms of Alzheimer disease go on for years, the phase 3 trials of the cholinesterase inhibitors (ChEIs), the current mainstay of symptomatic pharmacotherapy for this condition, were typically of only 3- to 6-months’ duration. We have limited data on long-term (that is, a year or more) therapy with these agents. In this review, we explore the available information on the biological and clinical effects of long-term ChEI therapy, what happens when these agents are discontinued, and examine what others have recommended. An individualized approach to deciding on whether to carry on with a ChEI should be taken. If continued, treatment goals should be clarified and patients monitored over time, for both drug-related benefits and adverse effects. PMID:25702360

    PurposeTo evaluate the safety, efficacy, and long-term results of endovascular stent graft placement for ureteroarterial fistula (UAF).MethodsWe retrospectively analyzed stent graft placement for UAF performed at our institution from 2004 to 2012. Fistula location was assessed by contrast-enhanced computed tomography (CT) and angiography, and freedom from hematuria recurrence and mortality rates were estimated.ResultsStent graft placement for 11 UAFs was performed (4 men, mean age 72.8 {+-} 11.6 years). Some risk factors were present, including long-term ureteral stenting in 10 (91 %), pelvic surgery in 8 (73 %), and pelvic radiation in 5 (45 %). Contrast-enhanced CT and/or angiography revealed fistula or encasement of the artery in 6 cases (55 %). In the remaining 5 (45 %), angiography revealed no abnormality, and the suspected fistula site was at the crossing area between urinary tract and artery. All procedures were successful. However, one patient died of urosepsis 37 days after the procedure. At a mean follow-up of 548 (range 35-1,386) days, 4 patients (36 %) had recurrent hematuria, and two of them underwent additional treatment with secondary stent graft placement and surgical reconstruction. The hematuria recurrence-free rates at 1 and 2 years were 76.2 and 40.6 %, respectively. The freedom from UAF-related and overall mortality rates at 2 years were 85.7 and 54.9 %, respectively.ConclusionEndovascular stent graft placement for UAF is a safe and effective method to manage acute events. However, the hematuria recurrence rate remains high. A further study of long-term results in larger number of patients is necessary.

    Introduction: Ureteral strictures can result in obstructive nephropathy and renal function deterioration. Surgical management of ureteral defects, especially in the proximal- and mid-ureter, is particularly challenging. Our purpose was to analyze the long-term outcomes of urothelial-based reconstructive surgery for upper- and mid-ureteral defects. Methods: We conducted a retrospective analysis of a single tertiary centre’s database, including 149 patients treated for ureteral defects between 2001 and 2011. Thirty-one patients (21%) underwent complex urothelial-based surgical repairs for upper- and mid-ureter defects. Patients’ median age was 61 years. The mean length of the ureteral strictures was 2.5 cm, located in upper-, mid-ureter, or in between in 19 (61%), 10 (32%), and two (6%) patients, respectively. All patients were treated with a primary urothelial-based repair. Median followup time was 26 months. The primary outcome of the study was the long-term preservation of renal function and lack of clinical obstruction. The secondary endpoint of the study was the assessment of the intra- and postoperative complication rates. Results: Most of the lesions were benign (22, 71%), while nine strictures (29%) were malignant. Seven patients (23%) suffered from postoperative complications, five of which were infectious. The median pre- and postoperative calculated glomerular filtration rates were 66 ml/min/1.72m2 and 64ml/min/1.72m2, respectively. Success rate was 84%, defined as lack of need for re-operation or kidney drainage at the last followup. Conclusions: Upper- and mid-ureteral defects present a complex pathology necessitating experienced reconstructive surgical skills. Our data suggest good long-term results for primary urothelial-based reconstructions for these pathologies. PMID:27695582

    Interim results from a number of ongoing, long-term environmental effects programs for composite materials are reported. The flight service experience is evaluated for 142 composite aircraft components after more than five years and one million successful component flight hours. Ground-based outdoor exposures of composite material coupons after 3 years of exposure at five sites have reached equilibrium levels of moisture pickup which are predictable. Solar ultraviolet-induced material loss is discussed for these same exposures. No significant degradation has been observed in residual strength for either stressed or unstressed specimens, or for exposures to aviation fuels and fluids.

    A patient whose chief concern was the esthetics of her anterior teeth presented for a second opinion after it had been recommended that crowns be placed throughout her mouth. Examination revealed numerous defective and some fractured restorations with recurring caries. With treatment goals including creating and maintaining a healthy periodontal environment, leveling the occlusal plane, and decreasing biomechanical risk, the treatment plan incorporated an interdisciplinary approach that utilized orthodontics, a Kois deprogrammer, and implant therapy. Demonstrating 6-year outcomes, this report discusses use of a method to assess treatment options based on expected long-term results.

    Review of the 74 patients undergoing aortic valve replacement with a Starr–Edwards ball-valve prosthesis between October 1963 and December 1967 showed that 16 died during surgery or within the first month after operation, usually owing to myocardial failure; and there were nine late deaths. The remaining patients developed few major complications, and the long-term results of operation are considered satisfactory, no patient being grossly incapacitated and most of them are leading active, symptom-free lives.

    Background: The Over-The-Scope Clip (OTSC®, Ovesco Endoscopy GmbH, Tübingen, Germany) is an innovative clipping device that provides a strong tissue grasp and compression without provoking ischemia or laceration. In this retrospective study we evaluated immediate and long-term success rates of OTSC deployment in various pathologies of the gastrointestinal (GI) tract. Methods: A total of 45 patients (35 female, 10 male) with an average age of 56 years old (range, 24–90 years) were treated with an OTSC for GI defects resulting from a diagnostic or interventional endoscopic procedure (acute setting group) or for fistula following abdominal surgery (chronic setting group). All procedures were performed with CO2 insufflation. Results: From January 2012 to December 2015 a total of 51 OTSCs were delivered in 45 patients for different kinds of GI defects. Technical success was always achieved in the acute setting group with an excellent clip adherence and a clinical long-term success rate of 100% (15/15). Meanwhile, considering the chronic setting group, technical success was achieved in 50% of patients with a long-term clinical success of 37% (11/30); two minor complications occurred. A total of three patients died due to causes not directly related to clip deployment. Overall clinical success rate was achieved in 58% cases (26/45 patients). A mean follow-up period of 17 months was accomplished (range, 1–36 months). Conclusion: OTSC deployment is an effective and minimally-invasive procedure for GI defects in acute settings. It avoids emergency surgical repair and it allows, in most cases, completion of the primary endoscopic procedure. OTSC should be incorporated as an essential technique of today’s modern endoscopic armamentarium in the management of GI defects in acute settings. OTSCs were less effective in cases of chronic defects. PMID:27582884

    Purpose: We have previously shown that delivering targeted radiotherapy to the tumour bed intraoperatively is feasible and desirable. In this study, we report on the feasibility, safety, and long-term efficacy of TARGeted Intraoperative radioTherapy (Targit), using the Intrabeam system. Methods and Materials: A total of 300 cancers in 299 unselected patients underwent breast-conserving surgery and Targit as a boost to the tumor bed. After lumpectomy, a single dose of 20 Gy was delivered intraoperatively. Postoperative external beam whole-breast radiotherapy excluded the usual boost. We also performed a novel individualized case control (ICC) analysis that computed the expected recurrences for the cohort by estimating the risk of recurrence for each patient using their characteristics and follow-up period. Results: The treatment was well tolerated. The median follow up was 60.5 months (range, 10-122 months). Eight patients have had ipsilateral recurrence: 5-year Kaplan Meier estimate for ipsilateral recurrence is 1.73% (SE 0.77), which compares well with that seen in the boosted patients in the European Organization for Research and Treatment of Cancer study (4.3%) and the UK STAndardisation of breast RadioTherapy study (2.8%). In a novel ICC analysis of 242 of the patients, we estimated that there should be 11.4 recurrences; in this group, only 6 recurrences were observed. Conclusions: Lumpectomy and Targit boost combined with external beam radiotherapy results in a low local recurrence rate in a standard risk patient population. Accurate localization and the immediacy of the treatment that has a favorable effect on tumour microenvironment may contribute to this effect. These long-term data establish the long-term safety and efficacy of the Targit technique and generate the hypothesis that Targit boost might be superior to an external beam boost in its efficacy and justifies a randomized trial.

    OBJECTIVE—To analyse the long term results of mechanical prostheses for treating active infective endocarditis.
DESIGN—Prospective cohort study of a consecutive series of patients diagnosed with infective endocarditis and operated on in the active phase of the infection for insertion of a mechanical prosthesis.
SETTING—Tertiary referral centre in a metropolitan area.
RESULTS—Between 1975 and 1997, 637 cases of infective endocarditis were diagnosed in the centre. Of these, 436 were left sided (with overall mortality of 20.3%). Surgical treatment in the active phase of the infection was needed in 141 patients (72% native, 28% prosthetic infective endocarditis). Mechanical prostheses were used in 131 patients. Operative mortality was 30.5% (40 patients). Ninety one survivors were followed up prospectively for (mean (SD)) 5.4 (4.5) years. Thirteen patients developed prosthetic valve dysfunction. Nine patients suffered reinfection: four of these (4%) were early and five were late. The median time from surgery for late reinfection was 1.4 years. During follow up, 12 patients died. Excluding operative mortality, actuarial survival was 86.6% at five years and 83.7% at 10 years; actuarial survival free from death, reoperation, and reinfection was 73.1% at five years and 59.8% at 10 years.
CONCLUSIONS—In patients surviving acute infective endocarditis and receiving mechanical prostheses, the rate of early reinfection compares well with reported results of homografts. In addition, prosthesis dysfunction rate is low and long term survival is good. These data should prove useful for comparison with long term studies, when available, using other types of valve surgery in active infective endocarditis.

    Purpose Retinitis Pigmentosa (RP) is a group of inherited retinal degenerations leading to blindness due to photoreceptor loss. A rare disease, it affects about 100,000 people in the United States. There is no cure and no approved medical therapy to slow or reverse RP. The purpose of this clinical trial was to evaluate the safety, reliability, and benefit of the Argus® II Retinal Prosthesis System (Second Sight Medical Products, Inc., Sylmar, CA) in restoring some visual function to subjects completely blind from RP. Herein, we report clinical trial results at 1 and 3 years post-implant. Design The study is a multicenter, single-arm, prospective clinical trial. Subjects There were 30 subjects in 10 centers in the U.S. and Europe. Subjects served as their own controls – i.e., implanted eye vs. fellow eye, and System ON vs. System OFF (native residual vision). Methods The Argus II System was implanted on and in a single eye (typically the worse-seeing eye) of blind subjects. Subjects wore glasses mounted with a small camera and a video processor that converted images into stimulation patterns sent to the electrode array on the retina. Main Outcome Measures The primary outcome measures were safety (the number, seriousness, and relatedness of adverse events) and visual function, as measured by three computer-based, objective tests. Results Twenty-nine out of 30 subjects remained implanted with functioning Argus II Systems at 3 years post-implant. Eleven subjects experienced a total of 23 serious device- or surgery-related adverse events. All were treated with standard ophthalmic care. As a group, subjects performed significantly better with the System ON than OFF on all visual function tests and functional vision assessments. Conclusions The three-year results of the Argus II trial support the long-term safety profile and benefit of the Argus II System for patients blind from RP. Earlier results from this trial were used to gain approval of the Argus II by the FDA

    OBJECTIVES: To define the effects of long-term thyroxine treatment upon heart rate, blood pressure, left ventricular systolic function, and left ventricular size, as well as indices of autonomic function, and to compare findings with those in patients with thyrotoxicosis before and during treatment. DESIGN: Cross sectional study of patients prescribed thyroxine long term (n = 11), patients with thyrotoxicosis studied at presentation (n = 23), compared with controls (n = 25); longitudinal study of patients with thyrotoxicosis studied at presentation and serially after beginning antithyroid drug treatment (n = 23). METHODS: 24 h ambulatory monitoring of pulse and blood pressure, echocardiography, forearm plethysmography, and autonomic function tests. RESULTS: Long-term thyroxine treatment in doses that reduced serum thyrotrophin to below normal had no effect on blood pressure, heart rate, left ventricular systolic function or stroke volume index, but was associated with an 18.4% increase in left ventricular mass index (mean (SEM) 101.9 (3.09) g/m2 v controls 86.1 (4.61), P < 0.01). Thryoxine treatment, like thyrotoxicosis, had no effect on tests of autonomic function. Untreated thyrotoxicosis resulted in pronounced changes in systolic and diastolic blood pressure and an increase in heart rate during waking and sleep. Patients with thyrotoxicosis at presentation had an increase in left ventricular systolic function (ejection fraction 70.5 (1.66)% v 65.4 (1.79), P < 0.01; fractional shortening 40.4 (1.54)% v 35.6 (1.46), P < 0.01), increased stroke volume index (45.9 (2.4) ml/m2 v 36.6 (1.7), P < 0.001), and an increase in forearm blood flow, and decrease in vascular resistance. They had a similar degree of left ventricular hypertrophy to that associated with thyroxine treatment (99.3 (4.03) g/m2); all changes were corrected within 2 months by antithyroid drugs. CONCLUSIONS: The development of left ventricular hypertrophy in patients receiving thyroxine in the absence

    Rescuing patients in severe cardiac failure with extracorporeal support remains challenging. The Gyro pump is a centrifugal blood pump and was now used for cardiopulmonary bypass, although it was originally developed for long-term cardiac assist. Little is known about clinical experiences using this pump. Here, we report on the clinical results of long-term extracorporeal life support for over 4 days using the Gyro pump with Excelung, a hollow fiber oxygenator coated with silicone and heparin. Seven patients underwent extracorporeal life support with 15 pump and oxygenator combinations. Gyro and Excelung were used for venoarterial extracorporeal support in six patients and for right ventricular support in one patient. Patient characteristics, pump driving conditions, and blood chemistry were obtained retrospectively. All pumps were subsequently disassembled and examined macroscopically, with 6 of 15 pumps also examined by scanning electron microscopy (SEM). The patient mortality rate was 57.1%. Mean duration of support was 10.5 ± 7.2 days per pump and oxygenator combination. Lactate dehydrogenase and aspartate aminotransferase were generally maintained below 1000 and 100 IU/L, respectively, after the first 4 days of pump driving. Thrombi were found in two pumps, one used without anticoagulation and the other driven at a very slow rotational speed. SEM revealed no wear in the male bearings and very low wear and deformation (0.02 ± 0.03 mm) in the female bearings. The combination of Gyro and Excelung may be applicable for long-term biventricular and right ventricular support, although proper anticoagulation should be administrated to avoid thrombus formation inside the pump.

    Objective: We compared long-term clinical outcomes of upper urinary tract transitional cell carcinoma (TCC) patients treated by retroperitoneoscopic nephroureterectomy (RNU) or open radical nephroureterectomy (ONU). Methods: Upper urinary tract TCC patients were treated with RNU (n = 86) or ONU (n = 72) and followed-up for more than three years. Demographic and clinical data, including preoperative indexes, intraoperative indexes and long-term clinical outcomes, were retrospectively compared to determine long-term efficacy of the two procedures. Results: The RNU and ONU groups were statistically similar in age, gender, previous bladder cancer history, tumour location, pathologic tumour stage, pathologic node metastasis or tumour pathologic grade. The original surgery time required for both RNU and ONU was statistically similar, but RNU was associated with a significantly smaller volume of intraoperative estimated blood loss and shorter length of postoperative hospital stay. Follow-up (average: 42.4 months, range: 3–57) revealed that the RNU 3-year recurrence-free survival rate was 62.8% and the 3-year cancer specific survival rate was 80.7%. In the ONU group, the 3-year recurrence-free survival and the three-year cancer-specific survival rates were 59.2% and 80.3%, respectively. Neither of the survival rates were statistically different between the two groups. T stage, grade, lymph node metastasis and bladder tumour history were risk factors for tumour recurrence; the operation mode and the bladder cuff incision mode had no correlation with the recurrence-free survival. Conclusion: The open surgery strategy and the retroperitoneoscopic nephroureterectomy strategy are equally effective for treating upper urinary tract TCC. However, the RNU procedure is less invasive, and requires a shorter duration of postoperative hospitalized care; thus, RNU is recommended as the preferred strategy. PMID:22630340

    2010-01-01

    Background In this study we aimed to evaluate the long-term outcome of diaphragmatic plication for symptomatic unilateral diaphragm paralysis. Methods Thirteen patients who underwent unilateral diaphragmatic plication (2 patients had right, 11 left plication) between January 2003 and December 2006 were evaluated. One patient died postoperatively due to sepsis. The remaining 12 patients [9 males, 3 females; mean age 60 (36-66) years] were reevaluated with chest radiography, flouroscopy or ultrasonography, pulmonary function tests, computed tomography (CT) or magnetic resonance imaging (MRI), and the MRC/ATS dyspnea score at an average of 5.4 (4-7) years after diaphragmatic plication. Results The etiology of paralysis was trauma (9 patients), cardiac by pass surgery (3 patients), and idiopathic (1 patient). The principle symptom was progressive dyspnea with a mean duration of 32.9 (22-60) months before surgery. All patients had an elevated hemidiaphragm and paradoxical movement radiologically prior to surgery. There were partial atelectasis and reccurent infection of the lower lobe in the affected side on CT in 9 patients. Atelectasis was completely improved in 9 patients after plication. Preoperative spirometry showed a clear restrictive pattern. Mean preoperative FVC was 56.7 ± 11.6% and FEV1 65.3 ± 8.7%. FVC and FEV1 improved by 43.6 ± 30.6% (p < 0.001) and 27.3 ± 10.9% (p < 0.001) at late follow-up. MRC/ATS dyspnea scores improved 3 points in 11 patients and 1 point in 1 patient at long-term (p < 0.0001). Eight patients had returned to work at 3 months after surgery. Conclusions Diaphragmatic plication for unilateral diaphragm paralysis decreases lung compression, ensures remission of symptoms, and improves quality of life in long-term period. PMID:21078140

    Background Several studies have reported associations between long-term exposure to ambient fine particulate matter (PM) and cardiovascular mortality. However, the health impacts of long-term exposure to specific constituents of PM2.5 (PM with aerodynamic diameter ≤ 2.5 μm) have not been explored. Methods We used data from the California Teachers Study, a prospective cohort of active and former female public school professionals. We developed estimates of long-term exposures to PM2.5 and several of its constituents, including elemental carbon, organic carbon (OC), sulfates, nitrates, iron, potassium, silicon, and zinc. Monthly averages of exposure were created using pollution data from June 2002 through July 2007. We included participants whose residential addresses were within 8 and 30 km of a monitor collecting PM2.5 constituent data. Hazard ratios (HRs) were estimated for long-term exposure for mortality from all nontraumatic causes, cardiopulmonary disease, ischemic heart disease (IHD), and pulmonary disease. Results Approximately 45,000 women with 2,600 deaths lived within 30 km of a monitor. We observed associations of all-cause, cardiopulmonary, and IHD mortality with PM2.5 mass and each of its measured constituents, and between pulmonary mortality and several constituents. For example, for cardiopulmonary mortality, HRs for interquartile ranges of PM2.5, OC, and sulfates were 1.55 [95% confidence interval (CI), 1.43–1.69], 1.80 (95% CI, 1.68–1.93), and 1.79 (95% CI, 1.58–2.03), respectively. Subsequent analyses indicated that, of the constituents analyzed, OC and sulfates had the strongest associations with all four outcomes. Conclusions Long-term exposures to PM2.5 and several of its constituents were associated with increased risks of all-cause and cardiopulmonary mortality in this cohort. Constituents derived from combustion of fossil fuel (including diesel), as well as those of crustal origin, were associated with some of the greatest risks

    Diabetes mellitus confers the highest mortality risk in primary and secondary cardiovascular prevention, but long-term prognosis differences between different forms of cardiovascular disease have not been assessed. We hypothesized that acute heart failure (HF) could have poorer outcomes than acute coronary heart disease (CHD) in patients with diabetes. We performed a prospective study of all consecutive patients admitted in a single year. Patients were categorized according to main cardiologic diagnosis: acute HF, acute CHD, rhythm disorders, or noncardiac disease. A total of 1,293 patients were included, 31.8% had diabetes and had higher mean age, more risk factors, previous cardiovascular disease, and co-morbidities. Hospital mortality (5.6% vs 1.7%; p <0.01) was higher in patients with diabetes. During follow-up (median 58.0 months; interquartile range 31.0 to 60.0), diabetic patients had higher cardiovascular mortality (27.2% vs 9.6%; p <0.01) and all-cause mortality (35.8% vs 14.5%; p <0.01); cardiovascular disease accounted for 75% of deaths. According to discharge diagnosis, patients with diabetes only had higher mortality rates in the subgroup of acute CHD. Acute HF was the diagnosis with higher cardiovascular (36.9%) and all-cause mortality (44.1%), followed by acute CHD (16.8% and 24.4%) and rhythm disorders (5.8% and 8.8%). Multivariate analysis identified an independent association with higher long-term mortality of acute HF and acute CHD in patients with and without diabetes. In conclusion, 1/3 of cardiology-admitted patients have diabetes and have poorer long-term prognosis, especially when discharged with the diagnosis of acute HF or acute CHD. PMID:26851962

    A pilot study was set up to assess the long-term effects of once weekly versus once monthly follow-up of pulmonary rehabilitation after a comprehensive home rehabilitation program on physical performance in patients with chronic obstructive pulmonary disease (COPD) during an 18-mo period. Thirty-six patients with a mean FEV1 of 1.3 +/- 0.4 L (43% pred) were included in the study. Groups A and B (n = 23) visited the physical therapist twice weekly for 3 mo. Thereafter, 11 patients (Group A) had a follow-up of pulmonary rehabilitation once a week, and 12 patients (Group B) had a follow-up once a month. Thirteen patients received no rehabilitation at all (Group C). Long-term home rehabilitation does not appear to improve exercise tolerance; however, on the other hand, there is a deterioration in vital capacity (p < 0.01), walking distance (p < 0.01), and maximal work load (p < 0.05), as shown in the control group. A small improvement in exertional dyspnea (p < 0.01) after 18 mo and inspiratory muscle function (p < 0.05) after 12 mo was shown only in Group A. Because of the insufficient number of patients enrolled in this pilot study, no clear benefit on physical performance of long-term home rehabilitation with either weekly or monthly supervision could be demonstrated.

    This article describes the social positioning of older people living with Alzheimer's disease who scream in a long-term care home. Few studies have focused on the social positions taken by older people, their family and formal caregivers during interaction and their effects on screams. A secondary data analysis was conducted using Harré and Van Langenhove's positioning theory. The results show that older people are capable of positioning and repositioning themselves in relational patterns. Family and formal caregivers position older people who scream according to their beliefs about their lived experience. They also react emotionally to older people and try to influence their behaviors. Understanding the social positioning of older people with Alzheimer's disease brought out their capacities and their caregivers' concerns for their well-being. Interventions should focus on these strengths and on promoting healthy relations in the triads to enhance quality of care in long-term care homes. PMID:24339123

    2015-01-01

    Background Only 20% of iliac veins will recanalize on anticoagulation (AC) treatment alone and may, therefore, develop venous obstruction after iliofemoral deep venous thrombosis (DVT). A considerable number of these patients will suffer from post-thrombotic syndrome (PTS) leading to impaired quality of life in more than 50%. Endovascular treatment for iliac vein obstruction using stents is known to alleviate PTS symptoms in selected patients. Purpose To report the Danish long-term results of endovascular treatment with iliac stenting. Material and Methods From 2000 to 2013 consecutive patients were evaluated and 19 patients with severe venous claudication were identified and subsequently underwent angioplasty and stenting. AC treatment was prescribed for 6 months, and knee-high class II compression stocking recommended for 1 year. Scheduled follow-up was done in the outpatient clinic at 6 weeks, 3 months, and annually thereafter. Results Nineteen patients, all women, all with left-sided iliac vein obstruction, and all with severe PTS symptoms were included. The median follow-up time was 81 months (range, 1–146 months; mean, 69 months). Primary patency rate of the inserted iliac stent was 89% (17/19) and 16 patients (84 %) had almost or total symptom relief at follow-up. Conclusion Endovascular stenting of iliac obstruction in local anesthesia is minimally invasive and shows excellent long-term outcomes for patients suffering from PTS. PMID:26445677

    Coronary stent implantation has become an accepted treatment for selected patients but the long-term outcome after stent implantation has not been investigated in a large unselected population. This study reports clinical and angiographic results after coronary stent implantation in a consecutive group of 1000 patients treated between November 1989 and June 1994. A total of 2012 stents were implanted in 1216 lesions. The anticoagulation regimen after successful stenting was abolished in the last 499 patients, treated with aspirin and ticlopidina. Complex lesions (type B2, type C lesions and chronic total occlusions) were less frequent in the group with anticoagulation (67%, 355/529 lesions) than in the group without anticoagulation (76%, 485/641; p < 0.01). Vessel size was also significantly smaller in the group with no anticoagulation (3.21 +/- 0.50 mm vs 2.89 +/- 0.70 mm; p < 0.001). Procedural success was achieved in 96% of cases. Major complications occurred in 49 pts, including death (1%), emergency bypass surgery (2.7%), and myocardial infarction (2.1%). Subacute stent thrombosis, observed in 2.6% of the patients treated with anticoagulation, decreased to 1% in the last 499 patients receiving only antiplatelet drugs after high pressure stent expansion controlled with intravascular ultrasound (p < 0.05). Angiographic follow-up was obtained at a mean interval of 6.6 +/- 3.0 months in 718 patients (75% of the eligible candidates). The global restenosis rate (greater than 50% diameter stenosis) was 22%, with no statistically significant difference in patients with and without anticoagulation after stenting. Clinical follow-up was available in 890 patients at a mean interval of 14 +/- 17 months. Late cardiac events occurred in 251 patients and included: 159 repeat coronary angioplasties for restenosis (20%), 114 coronary angioplasties for de novo lesions (10%), 33 elective by-pass surgery operations (3.7%) and 42 late deaths (4.7%).

    Uncemented, threaded acetabular components with smooth surface treatment were widely used in continental Europe in the 1970s and 1980s for primary total hip arthroplasty (THA). Previously published studies showed high failure rates in the mid-term. In a consecutive series of 116 patients, 127 threaded cups with smooth surface treatment (Weill cup; Zimmer, Winterthur, Switzerland) were implanted in combination with one type of uncemented stem. Patients were followed up clinically and radiographically. Mean time of follow-up was 17 years (range 15–20). At the time of follow-up, the acetabular component had been revised or was awaiting revision in 30 hips (24%). Two hips were revised for infection and 23 for aseptic loosening. Four polyethylene liners were exchanged because of excessive wear. One hip was awaiting revision. The survival rate for all acetabular revisions including one hip awaiting revision was 75% (95%CI: 65–85%) at 17 years. These results support the view that smooth, threaded acetabular components do not provide satisfactory long-term fixation and should be abandoned. It is important to closely monitor patients with these components as the failure rate remains high in the long-term. PMID:19629480

    Objective To analyze the management of pediatric trauma and the efficacy of the Pediatric Trauma Score (PTS) in classifying injury severity and predicting prognosis. Design A retrospective case series. Setting The Children’s Hospital of Eastern Ontario, a major pediatric trauma centre. Patients One hundred and forty-nine traumatized children with 2 or more injuries to 1 body system or a single injury to 2 or more body systems. Interventions Use of the PTS and Glasgow Coma Scale score in trauma management. Main outcome measures Types of injuries sustained, complications, missed injuries, psychosocial effects and residual deficiencies. Results The average PTS was 8.5 (range from −3 to 11). The total number of injuries sustained was 494, most commonly closed head injury (86). Forty-two percent of children with an average trauma score of 8.5 were treated surgically. There were 13 missed injuries, and complications were encountered in 57 children, the most common being secondary to fractures. Forty-eight (32%) children had residual long-term deficiency, most commonly neurologic deficiency secondary to head injury. Conclusions Fractures should be stabilized early to decrease long-term complications. A deficiency of the PTS is the weighting of open fractures of a minor bone. For example, metacarpal fracture is given the same weight as an open fracture of the femur. Neuropsychologic difficulties secondary to trauma are a major sequela of trauma in children. PMID:11939656

    A cross-sectional study of 155 participants who underwent genetic testing for Lynch syndrome (LS) examined long-term psychosocial and behavioral outcomes. Participants completed standardized measures of perceived risk, psychosocial functioning, knowledge, and a questionnaire of screening activities. Participants were on average 47.3 years and had undergone testing a mean of 5.5 years prior. Eighty four (54%) tested positive for a LS mutation and 71 (46%) negative. For unaffected carriers, perceived lifetime risk of colorectal cancer was 68%, and surprisingly, 40% among those testing negative. Most individuals demonstrated normative levels of psychosocial functioning. However, 25% of those testing negative had moderate depressive symptoms, as measured by the Center for Epidemiologic Studies for Depression Scale, and 31% elevated state anxiety on the State-Trait Anxiety Inventory. Being female and a stronger escape - avoidant coping style were predictive of depressive symptoms. For state anxiety, similar patterns were observed. Quality of life and social support were significantly associated with lower anxiety. Carriers maintained higher knowledge compared to those testing negative, and were more engaged in screening. In summary, most individuals adapt to genetic test results over the long term and continue to engage in screening. A subgroup, including some non-carriers, may require added psychosocial support.

    Sequential panoramic radiographs were assessed for mandibular third molar development in 47 long-term survivors of childhood Hodgkin's disease after treatment with 37 Gy mantle field radiation. To make a comparison, panoramic radiographs of 149 healthy, nonirradiated children were reviewed for the presence of mandibular third molars. In children between the ages of 7 and 12 years, bilateral agenesis of mandibular third molars was more frequent in patients who had been treated with mantle radiation than in nonirradiated patients. Unilateral agenesis, crown hypoplasia, and root growth impairment of mandibular third molars were also found. Similar, apparent, radiation-induced developmental anomalies were noted in maxillary third molars of the irradiated patients.

    Background: There is a growing body of evidence that prenatal and early childhood exposure to arsenic from drinking water can have serious long-term health implications. Objectives: Our goal was to understand the potential long-term health and disease risks associated with in utero and early life exposure to arsenic, as well as to examine parallels between findings from epidemiological studies with those from experimental animal models. Methods: We examined the current literature and identified relevant studies through PubMed by using combinations of the search terms “arsenic”, “in utero”, “transplacental”, “prenatal” and “fetal”. Discussion: Ecological studies have indicated associations between in utero and/or early life exposure to arsenic at high levels and increases in mortality from cancer, cardiovascular disease and respiratory disease. Additional data from epidemiologic studies suggest intermediate effects in early life that are related to risk of these and other outcomes in adulthood. Experimental animal studies largely support studies in humans, with strong evidence of transplacental carcinogenesis, atherosclerosis and respiratory disease, as well as insight into potential underlying mechanisms of arsenic's health effects. Conclusions: As millions worldwide are exposed to arsenic and evidence continues to support a role for in utero arsenic exposure in the development of a range of later life diseases, there is a need for more prospective studies examining arsenic's relation to early indicators of disease and at lower exposure levels. - Highlights: • We review in utero and early-life As exposure impacts on lifelong disease risks. • Evidence indicates that early-life As increases risks of lung disease, cancer and CVD. • Animal work largely parallels human studies and may lead to new research directions. • Prospective studies and individual exposure assessments with biomarkers are needed. • Assessing intermediary endpoints may

    Parkinson's disease (PD) impairments are multidimensional, making it difficult to choose a single primary outcome when evaluating treatments to stop or lessen the long-term decline in PD. We review commonly used multivariate statistical methods for assessing a treatment's global impact, and we highlight the novel Global Statistical Test (GST) methodology. We compare the GST to other multivariate approaches using data from two PD trials. In one trial where the treatment showed consistent improvement on all primary and secondary outcomes, the GST was more powerful than other methods in demonstrating significant improvement. In the trial where treatment induced both improvement and deterioration in key outcomes, the GST failed to demonstrate statistical evidence even though other techniques showed significant improvement. Based on the statistical properties of the GST and its relevance to overall treatment benefit, the GST appears particularly well suited for a disease like PD where disability and impairment reflect dysfunction of diverse brain systems and where both disease and treatment side effects impact quality of life. In future long term trials, use of GST for primary statistical analysis would allow the assessment of clinically relevant outcomes rather than the artificial selection of a single primary outcome.

  4. Mid- and long-term clinical results of surgical therapy in unicameral bone cysts

    PubMed Central

    2011-01-01

    Background Unicameral (or simple) bone cysts (UBC) are benign tumours most often located in long bones of children and adolescents. Pathological fractures are common, and due to high recurrence rates, these lesions remain a challenge to treat. Numerous surgical procedures have been proposed, but there is no general consensus of the ideal treatment. The aim of this investigation therefore was to study the long-term outcome after surgical treatment in UBC. Methods A retrospective analysis of 46 patients surgically treated for UBC was performed for short and mid-term outcome. Clinical and radiological outcome parameters were studied according to a modified Neer classification system. Long-term clinical information was retrieved via a questionnaire at a minimum follow-up of 10 years after surgery. Results Forty-six patients (17 female, 29 male) with a mean age of 10.0 ± 4.8 years and with histopathologically confirmed diagnosis of UBC were included. Pathological fractures were observed in 21 cases (46%). All patients underwent surgery for UBC (35 patients underwent curettage and bone grafting as a primary therapy, 4 curettage alone, 3 received corticoid instillation and 4 decompression by cannulated screws). Overall recurrence rate after the first surgical treatment was 39% (18/46), second (17.4% of all patients) and third recurrence (4.3%) were frequently observed and were addressed by revision surgery. Recurrence was significantly higher in young and in male patients as well as in active cysts. After a mean of 52 months, 40 out of 46 cysts were considered healed. Prognosis was significantly better when recurrence was observed later than 30 months after therapy. After a mean follow-up of 15.5 ± 6.2 years, 40 patients acknowledged clinically excellent results, while five reported mild and casual pain. Only one patient reported a mild limitation of range of motion. Conclusions Our results suggest satisfactory overall long-term outcome for the surgical treatment of UBC

    Leaching studies on SRL-131 simulated defense waste glass have been carried out for a duration of two years. This glass contained nonradioactive elements and depleted uranium to simulate the waste content. The leachants used in this study were deionized water, a sodium bicarbonate/silicic acid solution (silicate water), a synthetic groundwater, and a high ionic strength K-Mg-Na-Cl brine. Two temperatures were used: 40/sup 0/C and 90/sup 0/C. The long-term results were in fair agreement with modeling calculations performed using the PHREEQE geochemical code. The leachability of SRL-131 glass from results up to two years followed the trend: deionized water > silicate water > synthetic groundwater > salt brine at 40/sup 0/C and deionized water approx. = synthetic groundwater > silicate water > salt brine at 90/sup 0/C. Solid state analyses are reported along with an Appendix containing a complete data set.

    The association between long-term arsenic exposure and peripheral vascular disease has been well documented in our previous epidemiologic studies. The purpose of this study was to evaluate whether long-term arsenic exposure could be associated with ischemic heart disease (IHD). A total of 462 subjects living in the blackfoot disease-hyperendemic villages along the southwestern coast of Taiwan and characterized by long-term arsenic exposure from drinking artesian well water was studied. The subjects were recruited from an epidemiologic cohort who participated in a health examination. IHD was diagnosed by coding the resting electrocardiograms with the Minnesota code. History of arsenic exposure was estimated through information obtained from a personal interview according to a structured questionnaire and the arsenic content in artesian well water of the villages. Cumulative arsenic exposure (CAE) was calculated as the sum of the products multiplying the arsenic concentration in artesian well water (mg/l) by the duration of drinking the water (years) in consecutive periods of living in the different villages. Among the subjects, 78 cases (16.9%) were diagnosed as having IHD. The prevalence rates of IHD for the age groups of 30-39, 40-49, 50-59, and >/=60 years were 4.9, 7.5, 16.8, and 30.7%, respectively (P<0.001). For those with CAE of 0, 0.1-14.9 and >/=15 mg/l-years, the prevalence rates of IHD were 5.2, 10.9 and 24.1%, respectively (P<0.001). The odds ratios (95% confidence intervals) for IHD were 1.60 (0.48, 5.34), and 3.60 (1.11, 11.65), respectively, for those with CAE of 0.1-14.9 and >/=15.0 mg/l-years, when compared with those lacking drinking water exposure to arsenic after multivariate adjustment. It is concluded that IHD in the arseniasis-hyperendemic villages in Taiwan was associated with long-term arsenic exposure.

    Introduction Popliteal artery aneurysms (PAA) are rare. Different surgical techniques for open surgical repair are possible. This study presents a single centre experience using open surgical repair with a medial approach (MA) and outlines differences between symptomatic (SLS) and asymptomatic (ALS) legs. Methods Data collection was performed retrospectively. The investigation period was from 1 January 1996 to 1 January 2013. Patients presented in the Outpatient Department and received a questionnaire concerning their quality of life. Data are presented as mean ± standard deviation. Mann–Whitney test and Cochran–Armitage test for trend was used for data analysis. Kaplan–Meier method was used to calculate limb salvage rates. p < 0.05 was considered statistically significant. Results We analyzed 16 ALS and 26 SLS with an average age of 63.5 ± 10 years. Preoperative ankle-brachial index (ABI) was 1.0 ± 0.2 for ALS (on control examination: 1.12 ± 0.24) and 0.08 ± 0.18 for SLS (on control examination 0.94 ± 0.14) (p < 0.05). Limb salvage rate was 100% for ALS and 86.7% for SLS (overall 93.3%). Primary patency rate for SLS was 85%, for ALS rate of 100%, respectively (overall 92.5%). ALS reached an average of 13.1 ± 2.7 points (SLS 11.4 ± 2.8) on a numeric point scale. Conclusion Open surgery is therapy and prevention of acute ischaemia all in one, especially for asymptomatic patients and delivers good long-term results. Endovascular therapies offer an alternative but long-term results are pending. Open surgery should still be considered as a gold standard therapy. PMID:25905015

    OBJECTIVE The purpose of this study was to evaluate long-term treatment results, radiation-related toxicity, and prognostic factors for the progression-free survival (PFS) of patients with pilocytic astrocytomas treated by means of stereotactic radiosurgery with a Leksell Gamma Knife. METHODS A total of 25 patients with pilocytic astrocytomas underwent Gamma Knife surgery during the period 1992-2002. The median target volume was 2700 mm(3) (range 205-25,000 mm(3)). The 18 patients treated with 5 daily fractions received a median minimum target dose of 25 Gy. Doses for the 2 patients treated with 10 fractions over 5 days (2 fractions delivered on the same day at least 6 hours apart) were 23 and 28 Gy. For the 5 patients treated with a single fraction, the minimum target dose ranged from 13 to 20 Gy (median 16 Gy). RESULTS Complete regression occurred in 10 patients (40%) and partial regression in 10 patients (40%). The 10-year overall survival rate was 96% and the 10-year PFS rate was 80%. Target volume appeared to be a significant prognostic factor for PFS (p = 0.037). Temporary Grade 3 toxicity appeared in 2 patients (8%), and these patients were treated with corticosteroids for 2 months. Permanent Grade 4 toxicity appeared in 2 patients (8%) and was associated with neurocognitive dysfunction. In these 2 individuals, the neurocognitive dysfunction was also felt to be in part the result of the additional therapeutic interventions (4 in one case and 6 in the other) required to achieve durable control of their tumors. CONCLUSIONS Radiosurgery represents an alternative treatment modality for small residual or recurrent volumes of pilocytic astrocytomas and provides long-term local control. Target volume appears to be the most important factor affecting PFS. PMID:26991883

    BACKGROUND Facial hyperhidrosis can lead to serious emotional distress. Video-assisted thoracic sympathectomy resolves symptoms effectively, though it may be associated with compensatory hyperhidrosis, which may be more common in patients undergoing resection of the second thoracic ganglion. Oxybutynin has been used as a pharmacological approach to facial hyperhidrosis but the long-term results of this treatment are unclear. OBJECTIVE To evaluate the use of low oxybutynin doses in facial hyperhidrosis patients for at least six months. METHODS 61 patients were monitored for over six months and assessed according to the following variables: impact of hyperhidrosis on quality of life (QOL) before treatment and after six weeks, evolution of facial hyperhidrosis after six weeks and at the last consultation, complaints of dry mouth after six weeks and on last return visit, and improvement at other hyperhidrosis sites. RESULTS Patients were monitored for 6 to 61 months (median=17 months). Thirty-six (59%) were female. Age ranged from 17-74 (median:45). Pre-treatment QOL was poor/very poor in 96.72%. After six weeks, 100% of patients improved QOL. Comparing results after six weeks and on the last visit, 91.8% of patients maintained the same category of improvement in facial hyperhidrosis, 3.3% worsened and 4.9% improved. Dry mouth complaints were common but not consistent throughout treatment. More than 90% of patients presented moderate/great improvement at other hyperhidrosis sites. CONCLUSION Patients who had a good initial response to treatment maintained a good response long-term, did not display tachiphylaxis and experienced improvement on other hyperhidrosis sites.

    The long-term cardiac effects of anterior-weighted thoracic mantle field radiotherapy were assessed in 25 patients treated for Hodgkin's disease. These patients underwent an evaluation that included a careful history and physical examination, ECG, M-mode echocardiogram, exercise ECG-gated radionuclide ventriculography, and cardiac catheterization. In these 25 patients evaluated 37-144 months (median, 96) after completion of thoracic mantle radiotherapy, eight had constrictive pericarditis; eight had occult constrictive pericarditis; three had an abnormal response to fluid challenge; three had suspected or proven occlusive coronary artery disease; and one each had a cardiomyopathy and diminished functional capacity on exercise testing. Only one patient appears to be normal after evaluation. The clinical spectrum of delayed-appearing radiation-induced cardiac disease in patients treated by anterior-weighted thoracic mantle fields and our suggestions for its treatment are discussed.

    A retrospective review was performed of 11 children and adolescents (less than 19 years of age) with diagnosed pituitary adenomas. The patients were treated with subtotal resection and postoperative irradiation (S + R) or with irradiation alone (RT) at the Radiation Oncology Center, Mallinckrodt Institute of Radiology, Washington University Medical Center, from January 1958 through December 1982. Patient conditions at diagnosis were acromegaly in one, Nelson's syndrome in one, prolactinoma in three, chromophobe adenoma in three, and Cushing's disease in three. Median follow-up was 15.6 years (range 6.3-29.5 years). Only two patients have had failure: one at 8.6 years and the other at 20.7 years following treatment. All four patients with visual field (VF) defects at diagnosis underwent S + R, with only one developing recurrent disease. The remaining seven patients, who did not have VF defects, received RT only, and there has been one failure in this group. None have suffered long-term visual complications. All have been able to continue school and/or work. Three of eight females have borne children. Hypopituitarism requiring medication occurred in all who received S + R and in four of seven who received RT only.

    We present long-term spectral and timing results from an INTEGRAL monitoring program of persistently bright neutron star Low-Mass X-ray Binaries, i.e. the three bright Atoll sources GX 3+1, GX 9+1 and GX 9+9, and the Z sources GX 5-1, GX 17+2, GX 340+0 and GX 349+2. From the available observing periods between 2003 and 2009, each lasting ~2 months, we have selected a few sample periods for each source, and analyzed all JEM-X and IBIS/ISGRI data with offsets <4 degrees. We seek an explanation for the dichotomy between the hard X-ray tails or lack thereof in the (otherwise very similar) X-ray spectra of Z sources and bright Atolls, respectively.

    Patients with peri-acetabular osteolysis around a well fixed cementless acetabular component may be treated with liner exchange. When the locking mechanism is unreliable or unavailable, cementing the liner into the fixed acetabular component is a feasible option. The purpose of this study was to evaluate the clinical and radiographic long term results of this technique. Forty hip revisions with liner cementation in 37 patients were performed. The minimum follow up was 10 years. Modified Harris Hip Score and recent x rays were reviewed. Four hips were re-revised. Two patients were diagnosed with exacerbation of osteolysis but refused revision. Dislocation rate was relatively high (16%). Liner cementation technique in revision hip surgery is useful in patients with a well fixed metal backed acetabular component.

    Treatment of hydroceles and spermatoceles with evacuation, followed by injection of the sclerosing agent Polidocanol 3% (Aetoxysklerol), is a simple, low cost alternative to surgery. For the patient, it is also less painful compared to sclerotherapy using tetracycline. This article shows that the long term results are very promising. 28 patients, of whom two were treated for bilateral celes, gave us a total of 30 treatments. We interviewed the patients 62 months (52-67 months) after treatment, and found that in 24 of the 30 treatments there were no sign of relapse. In three cases the patient had noticed a small relapse, but had no pain. Three have later been treated with surgery.

    The medical records of 65 dogs that underwent complete or partial ligation of a single congenital portosystemic shunt (CPSS) were reviewed to determine the long-term clinical clinical results. Information retrieved from the records included age at surgery, preligation (baseline) portal pressure, postligation portal pressure, change in portal pressure from baseline, complete or partial occlusion of the shunting vessel and fasting, and 2-hour postprandial bile acids from the preoperative, early postoperative (PO), and greater than 1 year PO time periods. A clinical rating score derived from a follow-up examination greater than 1 year PO was assigned to each dog. Of the 56 dogs that survived the perioperative period, 29 (52%) had complete and 27 (48%) had partial ligations. Age at surgery, pre- and postligation portal pressure, change in portal pressure from baseline and serum bile acid concentrations were not related to long-term clinical outcome. Clinical rating scores were significantly greater for dogs with partial CPSS ligations compared with dogs with complete ligations, indicating a less favorable clinical outcome for partial ligations. Fasting and 2-hour postprandial bile acid values at both PO time intervals were significantly greater in partial versus complete ligation groups. Follow-up information for more than 1 year was available on 18 of 29 dogs (62%) with complete ligations. All were clinically normal. Of 27 dogs with partial ligations, 11 dogs (41%) developed recurrence of clinical signs resulting in presentation to the university or referring veterinarian for additional surgery, medical management, or euthanasia. Only three dogs with partial CPSS ligation (11%) were clinically normal.(ABSTRACT TRUNCATED AT 250 WORDS) PMID:7571385

    The U.S. Department of Energy (DOE) has tasked MSE Technology Applications, Inc. (MSE) with evaluating the long-term stability of various commercially available sorbent materials to solidify two organic surrogate waste streams (both volatile and nonvolatile), a volatile organic waste stream with a residual aqueous phase, an aqueous waste stream, and an aqueous waste stream with a residual organic phase. The Savannah River Site (SRS) legacy plutonium/uranium extraction (PUREX) process waste and the F-Canyon PUREX waste constituted the volatile organic wastes and various oils constituted the nonvolatile organic waste stream. The aqueous waste streams included a rainwater waste stream and an aqueous organic waste stream. MSE also evaluated the PUREX waste stream with a residual aqueous component with and without aqueous-type sorbent materials. Based on testing performed at MSE, the rainwater waste stream was successfully solidified by SRS personnel using two different sorbents. Several small oil wastes were also successfully solidified by SRS personnel using granular clay sorbents based on information provided by MSE from the oils waste stream testing and 75,706 Liters (L) [20,000 gallons (gal)] of the F-Canyon PUREX waste was solidified at Waste Consolidation Specialists (WCS). Solidification of the various surrogate waste streams listed above was performed from 2004 to 2006 at the MSE testing and evaluation facility located at the Mike Mansfield Advanced Technology Center in Butte, Montana. This paper summarizes the comparison of the initial liquid release testing (LRT) values with LRT results obtained over three years later in an attempt to understand the long-term stability characteristics of the solidified waste streams. The paper also includes solidification results for B-25 box samples generated late in 2005. (authors)

    A comprehensive study was conducted to examine the performance and possible changes in the effectiveness of landfill surface covers. Three different profiles of mineral landfill caps were examined. The results of precipitation and flow measurements show distinct seasonal differences which are typical for middle-European climatic conditions. In the case of the simple landfill cap design consisting of a thick layer of loamy sand, approximately 100-200 L m(-2) of annual seepage into the landfill body occurs during winter season. The three-layer systems of the two other test fields performed much better. Most of the water which percolated through the top soil profile drained sideways in the drainage layer. Only 1-3% of precipitation percolated through the sealing layer. The long-term effectiveness of the mineral sealing layer depended on the ability of the top soil layer to protect it from critical loss of soil water/critical increase of suction. In dry summers there was even a loss in soil water content at the base of the 2.0 m thick soil cover. The results of this study demonstrate the importance of the long-term aspect when assessing the effectiveness of landfill covers: The hydraulic conductivity at the time of construction gives only an initial (minimum) value. The hydraulic conductivity of the compacted clay layer or of the geosynthetic clay liner may increase substantially, if there is no long-lasting protection against desiccation (by a thick soil cover or by a geomembrane). This has to be taken into account in landfill cover design. PMID:20937619

    AIM To evaluate the long term clinical results of mechanical no-alcohol-assisted laser epithelial keratomileusis (LASEK) versus standard photorefractive keratectomy (PRK) for low-moderate myopia. METHODS Twenty-five eyes treated with LASEK and twenty-five eyes treated with PRK were evaluated with a mean follow-up duration of 60mo. Mechanical separation of the epithelium was performed with blunt spatula and without application of alcohol. Laser ablation was performed with the MEL-70 excimer laser. All patients were examined daily until epithelial closure; at 1, 3, 6, and 12mo, and every year subsequently. Main outcome measures were uncorrected distance visual acuity (UDVA), corrected distance visual acuity (CDVA), manifest refraction, haze, efficacy and safety indexes. RESULTS Twenty-one eyes and 22 eyes completed follow-up of 60mo in LASEK and PRK group respectively. Manifest refraction at 60mo follow-up was -0.01 and 0.26 in LASEK and PRK group respectively. In the LASEK group mean UDVA and mean CDVA after 60mo were 20/22 and 20/20 respectively (P>0.01). In the PRK group mean UDVA and mean CDVA at 60mo follow-up were 20/20 and 20/20 after 60mo (P>0.01). The efficacy indexes were 0.87 and 0.95, and the safety indexes were 1.25 and 1.4 respectively for LASEK group and PRK group. CONCLUSION Both standard PRK and no-alcohol LASEK offer safe and effective correction of low-moderate myopia in the long term without any statistically significant difference between the two groups.

    Social isolation in adulthood is a psychosocial stressor that can result in endocrinological and behavioral alterations in different species. In rodents, controversial results have been obtained in fear conditioning after social isolation at adulthood, while neural substrates underlying these differences are largely unknown. Neural cell adhesion molecule (NCAM) and its polysialylated form (PSA-NCAM) are prominent modulators of synaptic plasticity underlying memory processes in many tasks, including fear conditioning. In this study, we used adult female Octodon degus to investigate the effects of long-term social isolation on contextual and cued fear conditioning, and the possible modulation of the synaptic levels of NCAM and PSA-NCAM in the hippocampus. After 6½ months of social isolation, adult female degus showed a normal auditory-cued fear memory, but a deficit in contextual fear memory, a hippocampal dependent task. Subsequently, we observed reduced hippocampal synaptic levels of PSA-NCAM in isolated compared to grouped-housed female degus. No significant differences were found between experimental groups in hippocampal levels of the three main isoforms of NCAM (NCAM180, NCAM140 and NCAM120). Interestingly, social isolation reduced the volume of the hippocampal CA1 subfield, without affecting the volume of the CA3 subregion or the total hippocampus. Moreover, attenuated body weight gain and reduced number of granulocytes were detected in isolated animals. Our findings indicate for the first time, that long-term social isolation of adult female animals induces a specific shrinkage of CA1 and a decrease in synaptic levels of PSA-NCAM in the hippocampus. These effects may be related to the deficit in contextual fear memory observed in isolated female degus.

    Objective The objective of this study was to assess the long-term safety of linezolid in patients with chronic infections requiring treatment for ≥6 weeks. Enhanced monitoring for optic neuropathy was included to characterize the early development of this side effect and to identify ophthalmologic tests that might be valuable in early detection of this event. Methods This was a multicenter, open-label, pilot study of patients aged ≥18 years on long-term linezolid therapy. Matched control patients were included for baseline assessment comparison. Patients were assessed at study entry, monthly while on treatment, at the end of treatment, and 30 days following the last dose. Aggregate ocular safety data were reviewed. Response to treatment was reported. Results The study was terminated owing to slow enrollment. Twenty-four patients received linezolid; nine patients were included as matched controls. Linezolid was prescribed for a median of 80.5 days (range, 50–254 days). In patients with a reported clinical outcome, the majority were considered improved or cured. Common treatment-related adverse events (AEs) included anemia, peripheral neuropathy, polyneuropathy, vomiting, and asthenia, and were consistent with the known safety profile. Most AEs resolved or stabilized with discontinuation of treatment. Results of ophthalmologic tests in the one case adjudicated as probable linezolid-associated optic neuropathy revealed abnormal color vision, characteristic changes in the optic disk, and central scotomas in each eye. Conclusion In our small population, linezolid was generally well tolerated and AEs were consistent with the known safety profile. Extensive ophthalmologic testing of all 24 linezolid-treated patients identified one case adjudicated as probable, linezolid-associated optic neuropathy. PMID:27621644

    Using in vitro techniques, bone marrow (BM) function has been studied in 25 patients in complete remission and at least one year after the completion of MVPP chemotherapy for Hodgkin's disease. The numbers of granulocyte/macrophage (GM-CFC) and fibroblastoid (CFU-F) progenitors were significantly lower than controls and there was no evidence of any improvement with time (median months off treatment was 30 for GM-CFC and 34 for CFU-F). In long-term BM culture production of haemopoietic cells were strikingly lower in the post-MVPP group and the development of adherent stromal cell populations was also significantly less. In addition, the yield of GM-CFC in adherent layers after four weeks of culture was significantly lower than in controls. We conclude that following MVPP chemotherapy and in apparently disease free and haematologically normal individuals there is evidence of impaired BM function up to nine years after the completion of treatment. These abnormalities may be relevant to the known increased risk of acute non-lymphocytic leukaemias in this group of patients and are likely to render the BM less able to withstand subsequent insults such as further chemotherapy or infection. The eventual development of BM failure is also a possibility and long-term follow-up of these patients is essential. PMID:2390472

    The treatment of acromegaly is based on surgery, drugs, and radiotherapy as a third-line option. Fractionated stereotactic radiotherapy (FSRT) is a new technique with a need for long-term evaluation. The purpose of the study was to evaluate long-term results of FSRT in acromegaly. Overall, 34 patients [sex ratio 1.12, age 45 (5-65) years] with a pituitary adenoma of 24.5 (9-76) mm including 20 invasive tumors were treated by radiotherapy in fractionated stereotactic conditions delivering 50 gy in 27 sessions. Baseline growth hormone (GH) and IGF1 levels were 18 (±14.5) and 632.6 (±339) µg/L, respectively. Indications of FSRT were failure of surgery and drug treatments (n = 30) or contraindication/refusal of surgery (n = 4). Hormonal control was defined by normal age- and sex-adjusted IGF1. Remission was defined by hormonal control after withdrawal of drugs for a minimum of three consecutive months. Data were analyzed in SPSS software with a significance level at p < 0.05. After a mean follow-up of 152 months, hormonal control was achieved in 33 patients (97 %) with withdrawal of drugs in 13 patients (38.2 %) without any recurrence. Factors found to be significantly associated to remission in a multivariate Cox regression were lower baseline hormone levels (GH and IGF1) and smaller tumor size. Tumor control was achieved in all patients. Acquired hypopituitarism after radiotherapy was the main side effect reported with a rate of 39 %. FSRT seems to be an effective and well tolerated third-line treatment of acromegaly, particularly adapted to macro adenomas treatment.

    Purpose: Surgical resection is considered the desirable curative treatment for trigeminal schwannomas. However, complete resection without any complications remains challenging. During the last several decades, stereotactic radiosurgery (SRS) has emerged as a minimally invasive treatment modality. Information regarding long-term outcomes of SRS for patients harboring trigeminal schwannomas is limited because of the rarity of this tumor. The aim of this study was to evaluate long-term tumor control and functional outcomes in patients harboring trigeminal schwannomas treated with SRS, specifically with gamma knife surgery (GKS). Methods and Materials: Fifty-three patients harboring trigeminal schwannomas treated with GKS were evaluated. Of these, 2 patients (4%) had partial irradiation of the tumor, and 34 patients (64%) underwent GKS as the initial treatment. The median tumor volume was 6.0 cm{sup 3}. The median maximum and marginal doses were 28 Gy and 14 Gy, respectively. Results: The median follow-up period was 98 months. On the last follow-up image, 7 patients (13%) had tumor enlargement, including the 2 patients who had partial treatment. Excluding the 2 patients who had partial treatment, the actuarial 5- and 10-year progression-free survival (PFS) rates were 90% and 82%, respectively. Patients with tumors compressing the brainstem with deviation of the fourth ventricle had significantly lower PFS rates. If those patients with tumors compressing the brainstem with deviation of the fourth ventricle are excluded, the actuarial 5- and 10-year PFS rates increased to 95% and 90%, respectively. Ten percent of patients had worsened facial numbness or pain in spite of no tumor progression, indicating adverse radiation effect. Conclusions: GKS can be an acceptable alternative to surgical resection in patients with trigeminal schwannomas. However, large tumors that compress the brainstem with deviation of the fourth ventricle should be surgically removed first and then

    This presentation is about residents' reactions to sonic booms in a long-term sonic boom exposure environment. Although two phases of the data collection have been completed, the analysis of the data has only begun. The results are thus preliminary. The list of four authors reflects the complex multi-disciplinary character of any field study such as this one. Carey Moulton is responsible for Wyle Laboratories' acoustical data collection effort. Robert Baumgartner and Jeff Thomas of HBRS, a social science research firm, are responsible for social survey field work and data processing. The study is supported by the NASA Langley Research Center. The study has several objectives. The preliminary data addresses two of the primary objectives. The first objective is to describe the reactions to sonic booms of people who are living where sonic booms are a routine, recurring feature of the acoustical environment. The second objective is to compare these residents' reactions to the reactions of residents who hear conventional aircraft noise around airports. Here is an overview of the presentation. This study will first be placed in the context of previous community survey research on sonic booms. Next the noise measurement program will be briefly described and part of a social survey interview will be presented. Finally data will be presented on the residents' reactions and these reactions will be compared with reactions to conventional aircraft. Twelve community studies of residents' reactions to sonic booms were conducted in the United States and Europe in the 1960's and early 1970's. None of the 12 studies combined three essential ingredients that are found in the present study. Residents' long-term responses are related to a measured noise environment. Sonic booms are a permanent feature of the residential environment. The respondents' do not live on a military base. The present study is important because it provides the first dose/response relationship for sonic booms

    Background Tennis elbow is a common condition that usually responds to conservative measures. In refractory cases, surgical intervention is indicated. A plethora of surgical techniques have been described. We report the mid- to long-term outcomes of the Boyd–McLeod procedure for refractory tennis elbow. Methods A retrospective analysis and current review of patients that had undergone the Boyd–McLeod procedure over a 12-year period was undertaken. Demographics, time to discharge, length of follow-up and outcome scores were collected. Results Seventy patients underwent surgery. Mean time to discharge was 15.35 weeks, with 88% successful outcomes. Fifty-four patients were available for current follow-up at mean of 5.52 years (range 1.17 years to 11.49 years). Range of motion in all patients was unchanged. There were no revision procedures. Mean (SD) Mayo Elbow Performance Score was 90.85 (13.11), with 75.5% returning a good or excellent score and 24.5% a fair outcome. The mean (SD) Oxford Elbow Score was 44.04 (6.92); mean (SD) pain score was 89.5 (17.58); mean (SD) function score was 95.34 (9.59) and mean (SD) socio-psychological score was 91.50 (17.01). Overall, 83% of patients had an Oxford Elbow Score of 43 or greater, suggesting excellent outcome. Conclusions We show that the Boyd–McLeod procedure is an excellent option over both the short- and long-term for refractory tennis elbow. PMID:27582946

    Remote ischemic preconditioning (RIPre) can prevent myocardial injury. The purpose of this study was to assess the beneficial effects of long-term regular RIPre on human arteries. Forty patients scheduled for coronary artery bypass graft (CABG) surgery were assigned randomly to a RIPre group (n=20) or coronary heart disease (CHD) group (n=20). Twenty patients scheduled for mastectomy were enrolled as a control group. RIPre was achieved by occluding arterial blood flow 5 min with a mercury sphygmomanometer followed by a 5-min reperfusion period, and this was repeated 4 times. The RIPre procedure was repeated 3 times a day for 20 days. In all patients, arterial fragments discarded during surgery were collected to evaluate endothelial function by flow-mediated dilation (FMD), CD34(+) monocyte count, and endothelial nitric oxide synthase (eNOS expression). Phosphorylation levels of STAT-3 and Akt were also assayed to explore the underlying mechanisms. Compared with the CHD group, long-term regular RIPre significantly improved FMD after 20 days (8.5±2.4 vs 4.9±4.2%, P<0.05) and significantly reduced troponin after CABG surgery (0.72±0.31 and 1.64±0.19, P<0.05). RIPre activated STAT-3 and increased CD34(+) endothelial progenitor cell counts found in arteries. Long-term, regular RIPre improved endothelial function in patients with CHD, possibly due to STAT-3 activation, and this may have led to an increase in endothelial progenitor cells.

    Wilson's disease is an autosomal recessive disorder characterized by an accumulation of a toxic amount of copper in the body. Triethylene tetramine dihydrochloride (trientine, 2HCl) is a new chelating agent that may be effective in the removal of excess copper but long-term efficacy has not yet been investigated. Here we report the use of trientine over more than 8 years in 2 patients with Wilson's disease who could not tolerate D-penicillamine. We found no significant side effect, except a decreased serum iron concentration without clinical symptoms of anemia. In annual examinations at a steady state, the serum copper levels remained below 20 micrograms/100 ml. The 24-hour urinary copper excretion was less than that found using D-penicillamine, while the basal copper excretion, after 5 days abstinence from trientine, was maintained below 100 micrograms/day. Both hepatic and neurological manifestations except bulbar symptoms were recovered without any initial deterioration.

    Harmful alcohol drinking may lead to significant damage on any organ or system of the body. Alcoholic liver disease (ALD) is the most prevalent cause of advanced liver disease in Europe. In ALD, only alcohol abstinence was associated with a better long-term survival. Therefore, current effective therapeutic strategy should be oriented towards achieving alcohol abstinence or a significant reduction in alcohol consumption. Screening all primary care patients to detect those cases with alcohol abuse has been proposed as population-wide preventive intervention in primary care. It has been suggested that in patients with mild alcohol use disorder the best approach is brief intervention in the primary care setting with the ultimate goal being abstinence, whereas patients with moderate-to-severe alcohol use disorder must be referred to specialized care where detoxification and medical treatment of alcohol dependence must be undertaken.

    Twelve patients with hypoxemia associated with severe chronic obstructive pulmonary disease were treated with continuous portable oxygen therapy and have been followed up for a mean period of 25.2 months at sea level. Pulmonary function testing has revealed no further significant deterioration at long-term follow-up (17 months). After oxygen therapy was initiated, arterial carbon dioxide tension increased slightly, but decreased to pretreatment levels when patients were allowed to breathe room air. The electrocardiogram, which was unchanged at one month, has shown some reversal of cor pulmonale in five patients. Six patients have died, yielding a 56 percent survival rate at two-and-one-half years by the life table analysis. Five patients were autopsied, with possible oxygen toxicity being present in only one. The quality of life in our patients was improved and was especially represented by a reduction in hospital admissions for respiratory illness. We believe that continuous oxygen therapy is beneficial and worthwhile economically in certain patients.

    Background In contrast to the case fatality rate of patients diagnosed with meningococcal disease (MD) the long-term mortality in these patients is poorly documented. Methodology/Principal Findings We performed a nationwide, population-based cohort study including all Danish patients diagnosed with MD from 1977 through 2006 and alive one year after diagnosis. Data was retrieved from the Danish National Hospital Register, the Danish Civil Registration System and the Danish Register of Causes of Death. For each patient four age- and gender-matched individuals were identified from the population cohort. The siblings of the MD patients and of the individuals from the population cohort were identified. We constructed Kaplan-Meier survival curves and used Cox regression analysis, cumulative incidence function and subdistribution hazard regression to estimate mortality rate ratios (MRR) and analyze causes of death. We identified 4,909 MD patients, 19,636 individuals from the population cohort, 8,126 siblings of MD patients and 31,140 siblings of the individuals from the population cohort. The overall MRR for MD patients was 1.27 (95% confidence interval (CI), 1.12–1.45), adjusted MRR, 1.21 (95% CI, 1.06–1.37). MD was associated with increased risk of death due to nervous system diseases (MRR 3.57 (95% CI, 1.82–7.00). No increased mortality due to infections, neoplasms or cardiovascular diseases was observed. The MRR for siblings of MD patients compared with siblings of the individuals from the population cohort was 1.17 (95% CI, 0.92–1.48). Conclusions Patients surviving the acute phase of MD have increased long-term mortality, but the excess risk of death is small and stems mainly from nervous system diseases. PMID:20300639

    Stimulation of the subthalamic nucleus (STN) is an effective treatment for advanced Parkinson's disease (PD), but the medication requirements after implant are poorly known. We performed a long-term prospective evaluation of 20 patients maintained at stable dopaminergic therapy for 5 years after bilateral STN implants, who were evaluated 6 months, 1 year, 3 years, and 5 years after surgery. We measured, during the entire observation period, the effect of deep brain stimulation on motor and functional outcome measures, the levodopa equivalent daily dose and the total electrical energy delivered. At 5 years, the UPDRS motor score had improved by 54.2% and levodopa equivalent dose was reduced by 61.9%, compared with preimplant. Dopaminergic medication remained stable during the observation period, but energy was progressively increased over time. Rest tremor, rigidity, gait, lower and upper limb akinesia, and total axial score were improved in decreasing order. Postural stability and speech improved transiently, whereas on-period freezing of gait, motor fluctuations and dyskinesias recovered durably. Functional measures did not show improvement in autonomy and daily living activities after STN implant. Chronic STN stimulation allows to replace for dopaminergic medications in the long-term at the expense of an increase of the total energy delivered. This is associated with marked improvement of motor features without a matching benefit in functional measures.

    Purpose: We describe a retrospective study of initial and long-term outcomes with an open stent grafting (OSG) with a Matsui-Kitamura stent for treating thoracic aortic aneurysm. Methods: Between August 2005 and September 2013, 50 patients with aortic arch disease extending to the descending aorta underwent OSG. Circulatory arrest with total cardiopulmonary bypass and selective cerebral perfusion were used, and the aorta was transected between the brachiocephalic and left subclavian artery. The stent-graft was inserted, sutured to a transected aortic edge, and anastomosed to a four-branched arch graft. Preoperative, operative, and short- and long-term postoperative data were obtained from the patients’ medical records. Results: The perioperative (within 30 days) mortality rate was 8%. Two patients (4%) had a stroke and 5 patients (10%) had a spinal cord injury resulting in paraplegia or paraparesis (1 patient each) or transient paraplegia (3 patients). Actuarial survival rates at 1, 3, 5, and 7 years postoperatively were 87.8%, 78.3%, 70.7%, and 65.3%, respectively; the rates of freedom from an aortic event were 100%, 89.1%, 82.2%, and 74.7%. There were no complications related to use of the stent-graft. Conclusion: Our OSG method provided durable results in patients treated for thoracic aortic aneurysm, with few adverse events.

    Object. Video-assisted thoracoscopic sympathectomy is a safe, effective, and minimally invasive procedure for primary hyperhidrosis. This study aims to evaluate long-term results and patients' quality of life and investigate potential variables responsible for compensatory sweating after one-stage bilateral single-port thoracoscopic sympathectomy. Methods. Between 2005 and 2011, 260 consecutive bilateral thoracoscopic sympathectomies were performed in 130 patients for primary palmar and axillary hyperidrosis through one-port access. Residual pain, postoperative complications, recurrence of symptoms, heart rate adjustment, and quality of life were analyzed. Multivariate analysis was performed. Results. No operative mortality and conversion to open surgery were recorded. Mean operative time was 38 ± 5 minutes. Mean hospital stay was 1.1 ± 0.6 days. Eight patients (6%) had unilateral pneumothorax. Twenty-five cases (19%) were complicated by compensatory sweating. Winter and fall were identified as protective factors for compensatory sweating occurrence. Decreased heart rate was observed 1 year after surgery and permanently over the time. No recurrence during the follow-up period (31.5 months) was observed and 90% of patients showed improved quality of life. Conclusions. One-stage bilateral miniuniportal thoracoscopic sympathectomy is a valid and safe treatment for primary hyperhidrosis, achieving definitive and esthetic results, with excellent patients' satisfaction. Compensatory sweating may potentially occur in a season-dependent manner. PMID:24383050

    Clinical amelioration, clearance of Kayser-Fleischer rings and rising of ceruloplasmin concentration are described in a patient with the classical findings of Wilson's disease. These changes occurred during a 14-year period in which he used oral zinc sulphate (three times daily 200 mg) as the only medication to influence copper metabolism. Before starting this long-term zinc sulphate therapy he had used D-penicillamine (three times daily 300 mg) for only 6 weeks. The antagonistic action of zinc sulphate on copper resorption with amelioration of the clinical condition has been described before in this patient in 1961 by Schouwink. The patient had used at that time oral zinc sulphate for approximately 1.5 years. No changes in Kayser-Fleischer rings and ceruloplasmin levels were mentioned. Our findings suggest that oral zinc sulphate may not only prevent storage of copper in the tissues but may also contribute to the mobilization and excretion of deposits of copper.

    The purpose of this case study is to illustrate how music therapy can be used to help the elderly successfully adjust to living in a long-term care (LTC) facility. LTC residents, particularly those with Alzheimer's disease or related dementia, may exhibit behaviors such as depression, withdrawal, anxiety, emotional liability, confusion, and memory difficulties, frequently related to the disorder, but often exacerbated by difficulty in adjustment to the change in lifestyle. The subject of this case study demonstrated these symptoms. Music therapy helped him adjust to life in a LTC setting by improving his quality of life and enhancing his relationships with those around him. As chronicled in this study, music therapy may facilitate a resident's adjustment to life in a LTC facility. N.B. Names and identifying information have been changed to protect privacy.

  18. Management of low risk and low PSA prostate cancer: long term results from the prostate cancer intervention versus observation trial.

    PubMed

    Wilt, Timothy J

    2014-01-01

    Management of localized prostate cancer is controversial due in part to the lack of randomized controlled trial information in men diagnosed with prostate specific antigen (PSA) testing. Men with low risk or low PSA (<10 ng/ml) prostate cancer comprise up to 70 % of men currently diagnosed. Evidence suggests an excellent long-term prognosis with observation though nearly 90 % are treated with surgery (radical prostatectomy), external beam radiation, or brachytherapy. Results from the Prostate cancer Intervention Versus Observation Trial (PIVOT) provide high quality Level 1 evidence that observation compared to surgery results in similar long-term overall and prostate cancer survival, prevention of bone metastases and avoidance of surgery related harms. Combined with emerging evidence from screening, natural history, decision analysis and cost-effectiveness modeling studies, these data demonstrate that observation is the preferred treatment option for men with low risk and possibly low PSA prostate cancer. Recommending against PSA testing or, in men who still desire testing, raising thresholds of PSA values used to define abnormal, lengthening intervals between PSA tests and discontinuing testing in men with a life expectancy less than 15 years will reduce diagnostic and treatment related harms without adversely impacting overall or disease specific mortality and morbidity.

    Purpose: To describe the long-term outcomes from a completed, multi-institutional phase 4 registry trial using the Contura multilumen balloon (CMLB) breast brachytherapy catheter to deliver accelerated partial breast irradiation (APBI) in patients with early-stage breast cancer. Methods and Materials: Three hundred forty-two evaluable patients were enrolled by 23 institutions between January 2008 and February 2011. All patients received 34 Gy in 10 fractions, delivered twice daily. Rigorous target coverage and normal tissue dose constraints were observed. Results: The median follow-up time was 36 months (range, 1-54 months). For the entire patient cohort of 342 patients, 10 patients experienced an ipsilateral breast tumor recurrence (IBTR). Eight of these IBTR were classified as true recurrences/marginal miss (TRMM), and 2 were elsewhere failures (EF). Local recurrence-free survival was 97.8% at 3 years. For the entire cohort, 88% of patients had good to excellent overall cosmesis. The overall incidence of infection was 8.5%. Symptomatic seroma was reported in only 4.4% of patients. A separate analysis was performed to determine whether improved outcomes would be observed for patients treated at high-volume centers with extensive brachytherapy experience. Three IBTR were observed in this cohort, only 1 of which was classified as a TRMM. Local recurrence-free survival at high-volume centers was 98.1% at 3 years. Overall cosmetic outcome and toxicity were superior in patients treated at high-volume centers. In these patients, 95% had good to excellent overall cosmesis. Infection was observed in only 2.9% of patients, and symptomatic seroma was reported in only 1.9%. Conclusion: Use of the CMLB for APBI delivery is associated with acceptable long-term local control and toxicity. Local recurrence-free survival was 97.8% at 3 years. Significant (grade 3) toxicity was uncommon, and no grade 4 toxicity was observed. Treatment at high-volume centers was associated

    This study describes the long-term effectiveness on spatial neglect recovery of a 2-week treatment based on prism adaptation (PA). Seven right-brain-damaged patients affected by chronic neglect were evaluated before, after two weeks of the PA treatment and at a follow-up (variable between 8 and 30 months after the end of PA). Neglect evaluation was performed by means of BIT (conventional and behavioral), Fluff Test, and Comb and Razor Test. The results highlight an improvement, after the PA training, in both tasks performed using the hand trained in PA treatment and in behavioral tasks not requiring a manual motor response. Such effects extend, even if not significantly, to all BIT subtests. These results support previous findings, showing that PA improves neglect also on imagery tasks with no manual component, and provide further evidence for long-lasting efficacy of PA training. Dissociations have been found with regard to PA efficacy on peripersonal, personal, and representational neglect, visuospatial agraphia and neglect dyslexia. In particular, we found no significant differences between the pre-training and post-training PA session in personal neglect measures, and a poor recovery of neglect dyslexia after PA treatment. The recruitment of a larger sample could help to confirm the effectiveness of the prismatic lenses with regard to the different clinical manifestations of spatial neglect.

    Comparison of experimental data obtained from short (SDEF) and long duration exposure flights (LDEF) recently led to results, which will contribute for the estimation of genetic risk for long and/or repeated stay of man in space. Under orbital conditions biological stress and damage are induced in test subjects by cosmic radiation, especially the high energetic, densely ionizing component of heavy ions. Plant seeds were successful model systems for a biotest in studying the physiological damages and mutagenic effects caused by ionizing radiation in particular stem cells. In this article we present an overview of our space experiments with Arabidopis thaliana seeds. We present first results of investigations on certain damage endpoints (seed germination, plant survival, mutation frequencies), caused by cosmic ionizing radiation in dry dormant plant seeds ofArabidopsis thaliana after different short term (e.g. IML-1 and D-2) and long term (e.g. EURECA and LDEF-1) space exposures. Total dose effects of heavy ions and the other components of the mixed radiation field on damage endpoints and survival after space exposure and gamma-ray pre-irradiation were obtained. A new method of total dose spectrometry by neutron activation has been applied.

    The short-term benefits of levodopa/carbidopa intestinal gel (LCIG) in patients with advanced Parkinson's disease (PD) are well documented, but the long-term benefits are still uncertain. The aim of this study was to investigate the motor and cognitive outcome of LCIG treatment in advanced PD after a follow-up period of at least 24 months. We assessed 29 patients with advanced PD who started LCIG infusion at our centre between 2007 and 2013. Motor fluctuations, parkinsonian symptoms, activities of daily living and impact on quality of life were evaluated. We also investigated the cognitive outcome using a battery of neuropsychological tests. All adverse events were recorded. Of the 29 PD patients who initiated LCIG, 16 patients reached the follow-up evaluation (24 months), after a mean time period of 32.2 ± 12.4 months. Six patients did not fulfil the 24-month follow-up visit and were evaluated after a mean time period of 8.6 ± 5.4 months. Seven patients discontinued the treatment before the scheduled visit. "Off" time and "On" dyskinesia duration were significantly reduced. LCIG improved quality of life and non motor symptoms, despite overall unchanged total levodopa doses prior to LCIG beginning. Motor and cognitive decline were detected. A relatively high number of adverse events occurred during the follow-up, above all, technical problems with the infusion device and mild problems related with gastrostomy. There were four cases of peripheral neuropathy (PN), 2 of which were considered serious. Our data confirm that LCIG is beneficial in the long-term treatment of advanced PD patients despite a decline in cognitive functions in a subgroup of patients, probably due to disease progression. PN in patients with LCIG may be more frequent than the published date suggest. PMID:24477490

    Being born small for gestational age increases the risk of developing adult cardiovascular and metabolic diseases. This study aimed to examine if early-life exercise could increase heart mass in the adult hearts from growth restricted rats. Bilateral uterine vessel ligation to induce uteroplacental insufficiency and fetal growth restriction in the offspring (Restricted) or sham surgery (Control) was performed on day 18 of gestation in WKY rats. A separate group of sham litters had litter size reduced to five pups at birth (Reduced litter), which restricted postnatal growth. Male offspring remained sedentary or underwent treadmill running from 5 to 9 weeks (early exercise) or 20 to 24 weeks of age (later exercise). Remarkably, in Control, Restricted, and Reduced litter groups, early exercise increased (P < 0.05) absolute and relative (to body mass) heart mass in adulthood. This was despite the animals being sedentary for ~4 months after exercise. Later exercise also increased adult absolute and relative heart mass (P < 0.05). Blood pressure was not significantly altered between groups or by early or later exercise. Phosphorylation of Akt Ser(473) in adulthood was increased in the early exercise groups but not the later exercise groups. Microarray gene analysis and validation by real-time PCR did not reveal any long-term effects of early exercise on the expression of any individual genes. In summary, early exercise programs the heart for increased mass into adulthood, perhaps by an upregulation of protein synthesis based on greater phosphorylation of Akt Ser(473).

    Bilateral sagittal split osteotomy (BSSO) is a standard procedure in orthognathic surgery. The aim of the present study was to perform a matched pair analysis (bad sagittal split versus regular sagittal split) regarding the functional and radiographic long-term results after BSSO. Of 110 cases of mandibular hypoplasy treated with BSSO, 7 cases of bad sagittal splits (Group A) were selected, clinically examined and matched to 7 cases where no bad split occurred (Group B). The Research Diagnostic Criteria for Temporo Mandibular Disorders (RDC/TMD), condylar morphology scale (CMS) and ramus height measurements using orthopantomograms were carried out in the follow-up period to observe the clinical and functional status and condylar resorbtion or remodelling. The mean follow-up time was 28.6 months. The RDC/TMD examination did not show a higher incidence of temporomandibular dysfunction, including pain or clicking in the bad split group. Patients without a bad split showed statistically significant (p<0.05) better mouth opening. The CMS measurements were comparable in both groups. When compared with regular splits, bad splits, if treated in an appropriate manner, have a good chance of functional success, although, some mandibular movements can be compromised. PMID:18515045

    Despite evidence of potential antiobesity effects of high-protein (HP) diets, the impact of consuming diets with protein levels at the upper limit of the acceptable macronutrient distribution range (AMDR) on kidney health is unknown. To test whether HP diets affect renal health, whole plant and animal proteins in proportions that mimicked human diets were given to pigs, because their kidneys have a similar anatomy and function to those of humans. Adult female pigs received either normal-protein (NP) or HP (15 or 35% of energy from protein, respectively) isocaloric diets for either 4 or 8 mo. The higher protein in the HP diet was achieved by increasing egg and dairy proteins. Although there were initial differences in body weight and composition, after 8 mo these were similar in pigs consuming the NP and HP diets. The HP compared with NP diet, however, resulted in enlarged kidneys at both 4 and 8 mo. Renal and glomerular volumes were 60-70% higher by the end of the study. These enlarged kidneys had greater evidence of histological damage, with 55% more fibrosis and 30% more glomerulosclerosis. Renal monocyte chemoattractant protein-1 levels also were 22% higher in pigs given the HP diet. Plasma homocysteine levels were higher in the HP pigs at 4 mo and continued to be elevated by 35% at 8 mo of feeding. These findings suggest that long-term intakes of protein at the upper limit of the AMDR from whole protein sources may compromise renal health.

    As an alternative to open aneurysm repair, emergency endovascular aortic repair (EVAR) has emerged as a promising technique for ruptured abdominal aortic aneurysm (rAAA) within the last decade. The aim of this retrospective study is to present early and late outcomes of patients treated with EVAR for rAAA. Twenty-two patients (5 women, 17 men; mean age, 74 years) underwent EVAR for rAAA between November 2000 and April 2006. Diagnostic multislice computed tomography angiography was performed prior to stent-graft repair to evaluate anatomical characteristics and for follow-up examinations. Periprocedural patient characteristics and technical settings were evaluated. Mortality rates, hospital stay, and early and late complications, within a mean follow-up time of 744 {+-} 480 days, were also assessed. Eight of 22 patients were hemodynamically unstable at admission. Stent-graft insertion was successful in all patients. The total early complication rate was 54%, resulting in a 30-day mortality rate of 23%. The median intensive care unit stay was 2 days (range, 2-48 days), and the median hospital stay was 16 days (range, 9-210 days). During the follow-up period, three patients suffered from stent-graft-related complications. The overall mortality rate in our study group was 36%. EVAR is an acceptable, minimally invasive treatment option in patients with acute rAAA, independent of the patient's general condition. Short- and long-term outcomes are definitely comparable to those with open surgical repair procedures.

    Spinal epidural neurostimulation, which evolved from dorsal column stimulation, has been found to be effective in the treatment of acute and chronic intractable pain. Urban and Hashold have shown that it is a safe, simplified alternative to dorsal column stimulation, especially because laminectomy is not required if the electrodes are inserted percutaneously. Percutaneous epidural neurostimulation is also advantageous because there can be a diagnostic trial period before permanent internalization and implantation. This diagnostic and therapeutic modality has been used in 36 patients during the past 3 years at Northwestern Memorial Hospital. Eleven of these patients had acute intractable pain, which was defined as pain of less than 1 year in duration. Initial postimplantation results from the 36 patients indicate that spinal epidural neurostimulation is most effective in treating the intractable pain of diabetes, arachnoiditis, and post-traumatic and postamputation neuroma. Long term follow-up, varying from 1 year to 3 years postimplantation in the 20 initially responding patients, indicates that the neurostimulation continues to provide significant pain relief (50% or greater) in a majority of the patients who experienced initial significant pain relief.

    The purpose of this paper is to discuss the background to advanced surface modification technologies and to present a new technique, involving the formation of a titanium oxide ceramic coating, with relatively long-term results of its clinical utilization. Three general techniques are used to modify surfaces: the addition or removal of material and the change of material already present. Surface properties can also be changed without the addition or removal of material, through the laser or electron beam thermal treatment. The new technique outlined in this paper relates to the production of a corrosion-resistant 2000-2500 A thick, ceramic oxide layer with a coherent crystalline structure on the surface of titanium implants. The layer is grown electrochemically from the bulk of the metal and is modified by heat treatment. Such oxide ceramic-coated implants have a number of advantageous properties relative to implants covered with various other coatings: a higher external hardness, a greater force of adherence between the titanium and the oxide ceramic coating, a virtually perfect insulation between the organism and the metal (no possibility of metal allergy), etc. The coated implants were subjected to various physical, chemical, electronmicroscopic, etc. tests for a qualitative characterization. Finally, these implants (plates, screws for maxillofacial osteosynthesis and dental root implants) were applied in surgical practice for a period of 10 years. Tests and the experience acquired demonstrated the good properties of the titanium oxide ceramic-coated implants.

    Condylar fractures in childhood occur frequently, often with minimal pain and discomfort and therefore the diagnosis is not made at the time of injury. Management may be surgical or non-surgical. Non-surgical therapy in children is the method of choice if the condyle can translate normally. In fact, there is an excellent chance of regeneration and continued normal development after fracture in growing patients. The purpose of this article is to describe the long-term clinical and radiological evaluation of a conservatively treated unilateral condylar fracture, a result of trauma, in a 6-year-old patient. In addition, she presented a congenitally missing lower incisor ipsilateral to the fracture and a class II malocclusion. She was treated with functional jaw orthopedics using a splint and an activator and subsequent orthodontic treatment with fixed appliances [J Orofac Orthop5 (2002) 429]. The remodeling process of the condylar head and neck is clearly observed in the panoramic radiographs of the 12-year follow-up records presented. PMID:19239483

    Bilateral sagittal split osteotomy (BSSO) is a standard procedure in orthognathic surgery. The aim of the present study was to perform a matched pair analysis (bad sagittal split versus regular sagittal split) regarding the functional and radiographic long-term results after BSSO. Of 110 cases of mandibular hypoplasy treated with BSSO, 7 cases of bad sagittal splits (Group A) were selected, clinically examined and matched to 7 cases where no bad split occurred (Group B). The Research Diagnostic Criteria for Temporo Mandibular Disorders (RDC/TMD), condylar morphology scale (CMS) and ramus height measurements using orthopantomograms were carried out in the follow-up period to observe the clinical and functional status and condylar resorbtion or remodelling. The mean follow-up time was 28.6 months. The RDC/TMD examination did not show a higher incidence of temporomandibular dysfunction, including pain or clicking in the bad split group. Patients without a bad split showed statistically significant (p<0.05) better mouth opening. The CMS measurements were comparable in both groups. When compared with regular splits, bad splits, if treated in an appropriate manner, have a good chance of functional success, although, some mandibular movements can be compromised.

    The U.S. Department of Energy (DOE) Office of Legacy Management conducted annual sampling at the Rio Blanco, Colorado, Site for the Long-Term Hydrologic Monitoring Program (LTHMP) on May 20–21, 2015. This report documents the analytical results of the Rio Blanco annual monitoring event, the trip report, and the data validation package. The groundwater and surface water monitoring samples were shipped to the GEL Group Inc. laboratories for conventional analysis of tritium and analysis of gamma-emitting radionuclides by high-resolution gamma spectrometry. A subset of water samples collected from wells near the Rio Blanco site was also sent to GEL Group Inc. for enriched tritium analysis. All requested analyses were successfully completed. Samples were collected from a total of four onsite wells, including two that are privately owned. Samples were also collected from two additional private wells at nearby locations and from nine surface water locations. Samples were analyzed for gamma-emitting radionuclides by high-resolution gamma spectrometry, and they were analyzed for tritium using the conventional method with a detection limit on the order of 400 picocuries per liter (pCi/L). Four locations (one well and three surface locations) were analyzed using the enriched tritium method, which has a detection limit on the order of 3 pCi/L. The enriched locations included the well at the Brennan Windmill and surface locations at CER-1, CER-4, and Fawn Creek 500 feet upstream.

    The U.S. Department of Energy (DOE) Office of Legacy Management conducted annual sampling at the Rulison, Colorado, Site for the Long-Term Hydrologic Monitoring Program (LTHMP) on May 20–22 and 27, 2015. Several of the land owners were not available to allow access to their respective properties, which created the need for several sample collection trips. This report documents the analytical results of the Rulison monitoring event and includes the trip report and the data validation package (Appendix A). The groundwater and surface water monitoring were shipped to the GEL Group Inc. laboratories for analysis. All requested analyses were successfully completed. Samples were analyzed for gamma-emitting radionuclides by high- resolution gamma spectrometry. Tritium was analyzed using two methods, the conventional tritium method, which has a detection limit on the order of 400 picocuries per liter (pCi/L), and the enriched method (for selected samples), which has a detection limit on the order of 3 pCi/L.

    The main objective of this study is to evaluate the effect of immunomodulatory agents (IMAs) (Interferon-Beta, Glatiramer Acetate) in a large cohort of multiple sclerosis (MS) patients with disease onset in childhood or adolescence, treated before 16 years of age, after a long-term follow-up. A total of 130 patients were identified, 77 were treated with Avonex, 39 with Rebif/Betaferon, 14 with Copaxone. After a mean (SD) treatment duration of 53.6 +/- 27.0, 59.9 +/- 39.5 and 74.6 +/- 35.5 months, respectively, the relapse rate decreased significantly. The final EDSS score was unchanged with respect to the initial score. Similar results were also observed in subjects who continued a long-term follow-up after they were included in an observational study in 2004, and in subjects who were treated before 12 years of age. The frequency of clinical and laboratory adverse events was similar to that observed in adult patients. To conclude, IMAs were effective and well tolerated in paediatric patients with MS.

    Calcifying tendinitis (TC) of the rotator cuff is a transient shoulder disease with a high rate of spontaneous resorption of the deposit. Therefore, primary treatment should be conservative. In cases of persistent pain despite conservative treatment, extracorporeal shock wave therapy (ESWT) can be performed as an alternative minimally invasive method. Various short-term studies have demonstrated the efficiency of ESWT for TC. To evaluate the short- and long-term results, complications, and the number of operations avoided by ESWT, a prospective study with 115 patients was performed over a period of 4 years. The patients had received high-energy ESWT once (group A: n = 56) or twice (group B: n = 59). Six months after therapy, 47% in group A and 77% in group B showed evidence of disappearance or disintegration of the calcium deposits. Pain relief was achieved in 45% of group A and 53% of group B. Four years after treatment, 20% of the patients had undergone surgery on the involved shoulder. Of the remaining patients, 59% (68 patients) were seen for follow-up. Subjectively, 78% of group A and 87% of group B judged the treatment to be successful. X-ray examination revealed complete or partial resorption of the calcium deposit in 93% in both groups. The Constant score increased from 45 before treatment to 88 in group A and 85 in group B after treatment. ESWT was successful for about 70% of the treated patients with no long-term complications seen.

    Glucocorticoid disturbance can be a cause of psychiatric symptoms. Cushing's disease represents a unique model for examining the effects of prolonged exposure to high levels of endogenous cortisol on the human brain as well as for examining the relation between these effects and psychiatric symptomatology. This study aimed to investigate resting-state functional connectivity (RSFC) of the limbic network, the default mode network (DMN), and the executive control network in patients with long-term remission of Cushing's disease. RSFC of these three networks of interest was compared between patients in remission of Cushing's disease (n=24; 4 male, mean age=44.96 years) and matched healthy controls (n=24; 4 male, mean age=46.5 years), using probabilistic independent component analysis to extract the networks and a dual regression method to compare both groups. Psychological and cognitive functioning was assessed with validated questionnaires and interviews. In comparison with controls, patients with remission of Cushing's disease showed an increased RSFC between the limbic network and the subgenual subregion of the anterior cingulate cortex (ACC) as well as an increased RSFC of the DMN in the left lateral occipital cortex. However, these findings were not associated with psychiatric symptoms in the patient group. Our data indicate that previous exposure to hypercortisolism is related to persisting changes in brain function. PMID:25652248

    Objective. To assess the long-term effects of metformin in combination with lifestyle intervention and its association between insulin levels and the degree of steatosis at ultrasonography (US) in obese adolescents. Methods. Thirty-five postpubertal obese boys were randomized into two groups: one receiving metformin in combination with a multidisciplinary lifestyle intervention versus a placebo group, which also received the same intervention. The visceral, subcutaneous fat and degree of steatosis were measured by ultrasonography. Fasting blood samples were collected to analyze glucose, insulin, insulin resistance, and aminotransferases. Repeated ANOVA measures were used to compare changes over time and between groups, and Spearman's correlations were used to identify an association between insulin and the degree of steatosis at US. Results. There was a positive correlation between the degree of steatosis at US with insulin concentrations and HOMA-IR. Long-term therapy plus metformin significantly reduced body weight, body mass index, insulin, HOMA-IR, and visceral fat. Conclusions. Metformin was more effective than the placebo in improving clinical parameters associated with obesity and steatosis. PMID:20798858

    The aim of this retrospective study is to review long term results of full-thickness cartilage palisade tympanoplasty (FTCPT) with malleus head interposition performed on 51 patients (56 ears); 36 women and 15 men (7-73 years, 44 years average). The pathology of ears which encourages this technique of tympanoplasty is presented. On average 12 years after surgery we have elaborated anatomic and functional results. Anatomic results were categorized based on empiric evaluation of the new tympanic membrane status: 40 (71%) tympanic membranes without anatomic irregularities, 14 (25%) with irregularities and 2 (4%) with secondary perforation. Functional results (tonal audiogram) are based on pure tone average air-bone gap (PTA-ABG) at 4 frequencies. Main functional results of 51 ears (51 audiograms performed): pre- and post-operative average PTA-ABGs were 27.07 +/- 9.98 and 10.77 +/- 7.85 dB (t = 10.36; p < 0.001). In the group of ears with a tympanic membrane with no anatomic irregularities, pre- and post-operative average PTA-ABGs were 27.30 +/- 10.56 and 10.82 +/- 8.33 dB (t = 8.09; p < 0.001). In the group of ears with cartilage resorption, pre- and post-operative PTA-ABGs were 24.92 +/- 8.19 and 9.33 +/- 6.58 dB (t = 6.21; p < 0.001). The differences between the two groups are irrelevant. Postoperative PTA-ABG values of ears after first surgery (N = 34) and revision surgery (N = 17) was significantly different (8.75 +/- 5.75 and 15.16 +/- 9.62 dB) (t = 2.60; p = 0.016). In spite of the thickness of the new tympanal membrane, FTCPT is a successful technique for solving advanced ear pathology.

    Purpose the unstable osteochondritis dissecans (OCD-type II and III according to the ICRS classification) of the knee largher than > 2.5 cm2 in adults are uncommon lesions and there is no consensus on how to treat them. Medium-term studies have reported good results using autogenous osteochondral plugs (mosaicplasty). The aim of this study is to analyze the long-term results of this technique for the treatment of unstable OCD in a selected group of adult patients. Methods four patients with OCD at either one of the femoral condyles were included in this prospective study. The average age was 21.2 years (range, 18–24 years). The OCD lesions were classified as type II in three patients and type III in one patient and the average size was 3.8 cm2 (range, 2.55–5.1 cm2). The lesions were treated in situ with a variable number of autogenous osteochondral plugs (Ø 4.5 mm2). The Modified Cincinnati, Lysholm II and Tegner scores were used for clinical and functional evaluation. Magnetic resonance arthrography (MRA) was performed before surgery and at 2, 5 and 10 years after surgery. A modified MOCART score was used to evaluate MRA findings. Results the average follow-up duration was ten years and 6 months (range, 10–11 years). No complications occurred. At the final follow-up, all scores (clinical, functional and MOCART) improved. In all but one of the patients MRA showed complete osteochondral repair. Conclusions the fixation of large and unstable OCD lesions with mosaicplasty may be a good option for treating type II or III OCD lesions in adults. The advantages of this technique include stable fixation, promotion of blood supply to the base of the OCD fragment, and grafting of autologous cancellous bone that stimulates healing with preservation of the articular surface. Level of evidence Level IV, therapeutic case series. PMID:26904522

    Charcot–Marie–Tooth (CMT) disease is the most common inherited neuropathy and one of the most common inherited diseases in humans. The diagnosis of CMT is traditionally made by the neurologic specialist, yet the optimal management of CMT patients includes genetic counselors, physical and occupational therapists, physiatrists, orthotists, mental health providers, and community resources. Rapidly developing genetic discoveries and novel gene discovery techniques continue to add a growing number of genetic subtypes of CMT. The first large clinical natural history and therapeutic trials have added to our knowledge of each CMT subtype and revealed how CMT impacts patient quality of life. In this review, we discuss several important trends in CMT research factors that will require a collaborative multidisciplinary approach. These include the development of large multicenter patient registries, standardized clinical instruments to assess disease progression and disability, and increasing recognition and use of patient-reported outcome measures. These developments will continue to guide strategies in long-term multidisciplinary efforts to maintain quality of life and preserve functionality in CMT patients. PMID:26855581

    Adalimumab, a fully humanized monoclonal antibody against tumor necrosis factor-alpha (TNFα), has been evaluated in various randomized placebo-controlled trials in rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis and juvenile idiopathic arthritis. In the short time frame of these trials adalimumab has been shown to be effective in reducing disease activity, slowing radiographic disease progression and improving patients’ quality of life, while at the same time demonstrating an acceptable safety profile. Furthermore, release of adalimumab on the market, prospective observational studies, as well as open-label extensions of the original double-blind trials have provided experience and data about the long-term efficacy and safety of the drug. Initial effectiveness, in terms of reducing disease activity, is sustained, while in most cases patients treated with adalimumab experienced a slower radiographic progression and consequently less disability and improved health-related quality-of-life outcomes. Moreover, long-standing treatment of thousands of patients with adalimumab outside the controlled context of clinical trials was not related to new safety signals, with the most common adverse events being respiratory infections. The most common serious adverse events seem to be tuberculosis reactivation, while a putative association with malignant lymphoma development is not yet proven. Besides, both of these adverse reactions pertain to the whole TNFα blocker group. In conclusion, adalimumab is a safe and effective option for the treatment of patients with rheumatoid arthritis, ankylosing spondylitis, psoriatic arthritis and juvenile idiopathic arthritis.

    Background Hypothermia has been discussed as playing a role in improving the early phase of systemic inflammation. However, information on the impact of hypothermia on the local inflammatory response is sparse. We therefore investigated the kinetics of local and systemic inflammation in the late posttraumatic phase after induction of hypothermia in an established porcine long-term model of combined trauma. Materials & Methods Male pigs (35 ± 5kg) were mechanically ventilated and monitored over the study period of 48 h. Combined trauma included tibia fracture, lung contusion, liver laceration and pressure-controlled hemorrhagic shock (MAP < 30 ± 5 mmHg for 90 min). After resuscitation, hypothermia (33°C) was induced for a period of 12 h (HT-T group) with subsequent re-warming over a period of 10 h. The NT-T group was kept normothermic. Systemic and local (fracture hematoma) cytokine levels (IL-6, -8, -10) and alarmins (HMGB1, HSP70) were measured via ELISA. Results Severe signs of shock as well as systemic and local increases of pro-inflammatory mediators were observed in both trauma groups. In general the local increase of pro- and anti-inflammatory mediator levels was significantly higher and prolonged compared to systemic concentrations. Induction of hypothermia resulted in a significantly prolonged elevation of both systemic and local HMGB1 levels at 48 h compared to the NT-T group. Correspondingly, local IL-6 levels demonstrated a significantly prolonged increase in the HT-T group at 48 h. Conclusion A prolonged inflammatory response might reduce the well-described protective effects on organ and immune function observed in the early phase after hypothermia induction. Furthermore, local immune response also seems to be affected. Future studies should aim to investigate the use of therapeutic hypothermia at different degrees and duration of application.

    Background The relationship between ambient air pollution exposure and mortality of cardiovascular and cerebrovascular diseases in human is controversial, and there is little information about how exposures to ambient air pollution contribution to the mortality of cardiovascular and cerebrovascular diseases among Chinese. The aim of the present study was to examine whether exposure to ambient-air pollution increases the risk for cardiovascular and cerebrovascular disease. Methodology/Principal Findings We conducted a retrospective cohort study among humans to examine the association between compound-air pollutants [particulate matter <10 µm in aerodynamic diameter (PM10), sulfur dioxide (SO2) and nitrogen dioxide (NO2)] and mortality in Shenyang, China, using 12 years of data (1998–2009). Also, stratified analysis by sex, age, education, and income was conducted for cardiovascular and cerebrovascular mortality. The results showed that an increase of 10 µg/m3 in a year average concentration of PM10 corresponds to 55% increase in the risk of a death cardiovascular disease (hazard ratio [HR], 1.55; 95% confidence interval [CI], 1.51 to 1.60) and 49% increase in cerebrovascular disease (HR, 1.49; 95% CI, 1.45 to 1.53), respectively. The corresponding figures of adjusted HR (95%CI) for a 10 µg/m3 increase in NO2 was 2.46 (2.31 to 2.63) for cardiovascular mortality and 2.44 (2.27 to 2.62) for cerebrovascular mortality, respectively. The effects of air pollution were more evident in female that in male, and nonsmokers and residents with BMI<18.5 were more vulnerable to outdoor air pollution. Conclusion/Significance Long-term exposure to ambient air pollution is associated with the death of cardiovascular and cerebrovascular diseases among Chinese populations. PMID:21695220

    Chemical composition of soil organic carbon (SOC) is central to soil fertility. We hypothesize that change in SOC content resulting from various long-term fertilization strategies accompanies the shift in SOC chemical structure. This study examined the effect of fertilization strategies along with the time of fertilizer application on the SOC composition by 13C nuclear magnetic resonance (NMR) spectroscopy. The soils (Aquic Inceptisol) subjected to seven fertilizer treatments were collected in 1989, 1999 and 2009, representing 0, 10 and 20 years of fertilization, respectively. The seven fertilizer treatments were (1-3) balanced fertilization with application of nitrogen (N), phosphorus (P) and potassium (K) including organic compost (OM), half organic compost plus half chemical fertilizer (1/2OM), and pure chemical NPK fertilizer (NPK); (4-6) unbalanced chemical fertilization without application of one of the major elements including NP fertilizer (NP), PK fertilizer (PK), and NK fertilizer (NK); and (7) an unamended control (CK). The SOC content in the balanced fertilization treatments were 2.3-52.6% and 9.4-64.6% higher than in the unbalanced fertilization/CK treatments in 1999 and 2009, respectively, indicating significant differences in SOC content with time of fertilizer application between the two treatment groups. There was a significantly greater proportion of O-alkyl C and a lower proportion of aromatic C in the balanced fertilization than in unbalanced fertilization/CK treatments in 1999, but not in 2009, because their proportions in the former treatments approached the latter in 2009. Principal component analysis further showed that the C functional groups from various fertilization strategies tended to become compositionally similar with time. The results suggest that a shift in SOC chemical composition may be firstly dominated by fertilization strategies, followed by fertilization duration. PMID:25884713

    Purpose: We aimed to evaluate the effects of preoperative pulmonary hypertension (PH) on early and long term results in patients undergoing coronary bypass surgery and the effects of coronary bypass surgery on PH. Methods: Among 2325 patients who underwent elective isolated coronary artery bypass surgery between March 2003 and March 2012, 287 patients with high preoperative pulmonary arterial pressure (PAP) ≥30 mmHg were examined. Patients’ data were obtained by retrospective examination of our clinic’s database. 69 patients who had complete parameters included in the study. Results: There was no increase in the New York Heart Association (NYHA) functional classification 84% of cases. Preoperative and postoperative values of the mean ejection fraction and mean PAP of patients was respectively 45.28 ± 9.67 (25–65), 46.03 ±12.4 (20–65) (p = 0.447), 36.67 ± 6.81 (30–60) mmHg, 37.81 ± 10.07 (20–70) mmHg (p = 0.378). The late mortality of cases was 5.79%. In our study, during 33.9 ± 17 (9–100) months follow up period, life expectancy was calculated as 94.7 months. Conclusion: Preoperative evaluation of these patients for appropriate medical treatment at peroperative and postoperative period, coronary bypass can be performed with low morbidity and mortality rates. In the late period after surgical revascularization PH showed no significant change and had no adverse effect on quality of life. PMID:25753326

    MISTI Gold breast implants (Bioplasty, St. Paul, Minn.) filled with polyvinylpyrrolidone-hydrogel were developed as a promising alternative to silicone-filled implants. Some studies have reported on the positive effects of the implant, such as improved radiolucency and biocompatibility of the gel; however, there are also reports that such implants increased in volume and were subject to capsular contracture in the human body, resulting in demands for their removal. The purpose of this retrospective study was to analyze the long-term results of a series of patients with MISTI Gold breast implants. Between 1991 and 1993, the authors inserted 83 MISTI Gold implants in 61 patients with an average age of 46 years (range, 16 to 69). The authors were able to follow up 48 patients with 71 MISTI Gold implants. The average follow-up was 68 months (range, 10 to 108 months). The retrospective study found that 59 percent of all MISTI Gold implants were removed after an average period of 4.14 years. The main reason for implant removal was an increase in volume of 38 percent, followed by capsular contracture in 14 percent of all 71 MISTI Gold implants. The average increase in volume of all removed MISTI Gold implants was 43 percent. Capsular contracture was graded as Baker I and II in 63 percent and as Baker III and IV in 37 percent. In conclusion, the authors believe that MISTI Gold implants do not fulfill the criteria of safe breast implants, and they agree with the December of 2000 opinion of the Medical Devices Agency of the Department of Health in London that the hydrogel-filled breast implants should not be used until more information about the filler material and its metabolic fate is available.

The seven fertilizer treatments were (1-3) balanced fertilization with application of nitrogen (N), phosphorus (P) and potassium (K) including organic compost (OM), half organic compost plus half chemical fertilizer (1/2OM), and pure chemical NPK fertilizer (NPK); (4-6) unbalanced chemical fertilization without application of one of the major elements including NP fertilizer (NP), PK fertilizer (PK), and NK fertilizer (NK); and (7) an unamended control (CK). The SOC content in the balanced fertilization treatments were 2.3-52.6% and 9.4-64.6% higher than in the unbalanced fertilization/CK treatments in 1999 and 2009, respectively, indicating significant differences in SOC content with time of fertilizer application between the two treatment groups. There was a significantly greater proportion of O-alkyl C and a lower proportion of aromatic C in the balanced fertilization than in unbalanced fertilization/CK treatments in 1999, but not in 2009, because their proportions in the former treatments approached the latter in 2009. Principal component analysis further showed that the C functional groups from various fertilization strategies tended to become compositionally similar with time. The results suggest that a shift in SOC chemical composition may be firstly dominated by fertilization strategies, followed by fertilization duration.

    PURPOSE We aimed to evaluate the frequency of persistence and complication rates of pulmonary arteriovenous malformations (PAVMs) treated with Amplatzer vascular plug (AVP) or Amplatzer vascular plug type 2 (AVP2). METHODS We retrospectively reviewed a total of 22 patients with 54 PAVMs between June 2004 and June 2014. We included 12 patients with 35 PAVMs who received percutaneous embolization using AVP or AVP2 only without the use of any other embolic devices. The mean follow-up was 54±24.3 months (range, 31–97 months). The primary end-points of the study were the efficacy of embolotherapy, the increase in oxygen saturation, and the persistence of PAVM on follow-up. Secondary end point was the incidence of complications. RESULTS The study included 10 female and two male patients with a mean age of 50.2±13.7 years (range, 21–66 years). All PAVMs had a simple angioarchitecture. The technical success of the procedure for PAVM occlusion was 100%. There was a significant increase in the oxygen saturation following embolotherapy (P < 0.0001). Follow-up computed tomography angiography revealed successful treatment in 34 PAVMs (97%) and failed treatment in one PAVM (3%). Twenty-three aneurysmal sacs (67%) showed complete disappearance. The failed treatment was due to persistence of PAVM caused by subsequent development of systemic reperfusion, which did not require further intervention. There were two minor complications but no major complications were encountered. CONCLUSION Embolotherapy of PAVMs using AVP or AVP2 devices is safe and effective, with high technical success rate, low persistence and complication rates, and with excellent long-term results.

    The aim of this study was to investigate the prevalence of benzodiazepine and related drug (BZDR) use, especially long-term use, and associated factors among community-dwelling individuals with and without Alzheimer's disease (AD). We utilized data from the MEDALZ-2005 cohort, which includes all community-dwelling individuals diagnosed with AD in Finland at the end of 2005 and matched comparison individuals without AD. Register-based data included prescription drug purchases, comorbidities, and hospital discharge diagnoses. In this study, 24,966 individuals with AD and 24,985 individuals without AD were included. During the 4-year follow-up, we found that 45% (N = 11,312) of individuals with AD and 38% (N = 9534) of individuals without AD used BZDRs. The prevalence of long-term (≥ 180 days) BZDR use was more common among individuals with AD (30%) than individuals without AD (26%). The median durations of the first long-term use periods of BZDRs were 1.5 and 2 years for individuals with and without AD, respectively. Factors associated with long-term BZDR use included female sex, AD, schizophrenia, bipolar disorder, depression, coronary artery disease, and asthma/chronic obstructive pulmonary disease. The high prevalence of long-term BZDR use among individuals with AD is especially a cause for concern because long-term use may further impair cognition and may be associated with serious adverse events.

    Long-term results of treatment of 280 patients operated for multinodal euthyroid goiter (MNEG) in surgical department of Endocrinology Research Center RAMS from 1983 to 1997 were studied. Hormonal examination of peripheral blood, ultrasonic examination of thyroid gland (TG) and zones of regional lymph outflow, thin-needle punch biopsy were used as special methods of investigation. Correlation between recurrence and histological form was studied. In cystic-colloid goiter with adenomatosis the recurrence of MNEG was revealed in 15 (34.1%) cases. In primary multiple TG adenomas of different types the number of recurrences was smallest--1 (3.3%) cases. There were no recurrences in cancer of TG in combination with cystic-colloid goiter or adenomas of TG. Recurrence of cystic-colloid goiter was revealed in 5 (5.7%) cases, different types of adenomas--in 5 (5.7%) cases. The smallest number of recurrences of MNEG was seen after maximum subtotal resection of TG--in 4 patients (7.7% of the patients with this volume of operation). In all the 12 cases of partial resection of TG the recurrence of different morphological forms of MNEG was revealed. Influence of thyroid therapy on remote recurrence rate in different form of MNEG was also studied. In cystic-colloid goiter (CCG) of different proliferation degree with adenomatosis the recurrence rate was not significantly different irrespective of hormonal therapy--29.4%, 37.5% and 36.4%, respectively, in adequate therapy, inadequate therapy and its absence, that testifies to small influence of thyroid therapy on reduction of recurrence rate in this group of patients. The highest recurrence rate in CCG and CCG with adenomas of TG was revealed in the group without thyroid therapy--30.8% and 35.7%, respectively. PMID:11490491

    Cardiovascular disease frequently occurs after lymphoma therapy, but it is common in the general population too. Therefore, risk estimation requires comparison to population-based rates. We calculated risk by standardized incidence ratios (SIRs) and absolute excess risks (AERs) per 10,000 person-years based on general population rates (Continuous Morbidity Registry Nijmegen) in 476 (Dutch and Belgian) patients with aggressive non-Hodgkin lymphoma (NHL) treated with at least 6 cycles of doxorubicin-based chemotherapy in 4 European Organization for Research on Treatment of Cancer (EORTC) trials (1980-1999). Cumulative incidence of cardiovascular disease, estimated in a competing risk model, was 12% at 5 years and 22% at 10 years (median follow-up, 8.4 years). Risk of chronic heart failure appeared markedly increased (SIR, 5.4; 95% CI, 4.1-6.9) with an AER of 208 excess cases per 10 000 person-years, whereas risk of coronary artery disease matched the general population (SIR, 1.2; 95% CI, 0.8-1.8; AER, 8 per 10 000 person-years). Risk of stroke was raised (SIR, 1.8; 95% CI, 1.1-2.4; AER, 15 per 10 000 person-years), especially after additional radiotherapy (> 40 Gy). Preexisting hypertension, NHL at young age, and salvage treatment increased risk of all cardiovascular events; the effect of radiotherapy was dose dependent. In conclusion, patients are at long-term high risk of chronic heart failure after NHL treatment and need therefore life-long monitoring. In contrast, risk of coronary artery disease appeared more age dependent than treatment related. PMID:16339404

    Diabetes is the fifth leading cause of death worldwide and contributes to leading causes of death, cancer and cardiovascular disease including coronary heart disease, stroke, peripheral vascular disease and other vascular disease. While glycemic management remains a cornerstone of diabetes care, the co-management of hypertension, atherosclerosis, cardiovascular risk reduction and prevention of long-term consequences associated with diabetes are now well recognized as essential to improve long-term survival. Clinical trial evidence substantiates the importance of glycemic control, LDL-cholesterol lowering therapy, blood-pressure lowering, control of albuminuria, and comprehensive approaches targeting multiple risk factors to reduce cardiovascular risk. This article presents a review of the role of diabetes in pathogenesis of atherosclerosis and cardiac dysfunction, recent evidence regarding degree of glycemic control and mortality, and available evidence for a multi-faceted approach to improve long-term outcomes for patients.

    High-precision atmospheric CO2 has been monitored in several locations through the Salt Lake Valley metropolitan region of northern Utah over the past nine years. Many parts of this semi-arid grassland have transitioned into dense urban forests, supported totally by extensive homeowner irrigation practices. Diurnal changes in fossil-fuel energy uses and photosynthesis-respiration processes have resulted in significant spatial and temporal variations in atmospheric CO2. Here we present an analysis of the long-term patterns and trends in midday and nighttime CO2 values for four sites: a midvalley residential neighborhood, a midvalley non-residential neighborhood, an undeveloped valley-edge area transitioning from agriculture, and a developed valley-edge neighborhood with mixed residential and commercial activities; the neighborhoods span an elevation gradient within the valley of ~100 m. Patterns in CO2 concentrations among neighborhoods were examined relative to each other and relative to the NOAA background station, a desert site in Wendover, Utah. Four specific analyses are considered. First, we present a statistical analysis of weekday versus weekend CO2 patterns in the winter, spring, summer, and fall seasons. Second, we present a statistical analysis of the influences of high-pressure systems on the elevation of atmospheric CO2 above background levels in the winter versus summer seasons. Third, we present an analysis of the nighttime CO2 values through the year, relating these patterns to observed changes in the carbon isotope ratios of atmospheric CO2. Lastly, we examine the rate of increase in midday urban CO2 over time relative to regional and global CO2 averages to determine if the amplification of urban energy use is statistically detectable from atmospheric trace gas measurements over the past decade. These results show two important patterns. First, there is a strong weekday-weekend effect of vehicle emissions in contrast to the temperature

    OBJECTIVE--To investigate the long-term results of the corridor operation in the treatment of symptomatic atrial fibrillation refractory to drug treatment. BACKGROUND--The corridor operation is designed to isolate from the left and right atrium a conduit of atrial tissue connecting the sinus node area with the atrioventricular node region in order to preserve physiological ventricular drive. The excluded atria can fibrillate without affecting the ventricular rhythm. This surgical method offers an alternative treatment when atrial fibrillation becomes refractory to drug treatment. PATIENTS--From 1987 to 1993, 36 patients with drug refractory symptomatic paroxysmal atrial fibrillation underwent surgery. The in hospital rhythm was followed thereafter by continuous rhythm monitoring and with epicardial electrograms. After discharge Holter recording and stress testing were regularly carried out to evaluate the sinus node function and to detect arrhythmias; whereas Doppler echocardiography was used to measure atrial contraction and size. MAIN OUTCOME MEASURES--Maintained absence of atrial fibrillation without drug treatment after operation; preservation of normal chronotropic response in the sinus node. RESULTS--The corridor procedure was successful in 31 (86%) of the 36 patients. After a mean (SD) follow up of 41 (16) months 25 (69%) of the 36 patients were free of arrhythmias without taking drugs (mean (SE) actuarial freedom at four years 72 (9)%)). Paroxysmal atrial fibrillation recurred in three patients; paroxysmal atrial flutter (two patients) and atrial tachycardia (one patient) developed in the corridor in three others. Among the 31 patients in whom the operation was successful sinus node function at rest and during exercise remained undisturbed in 26 and 25 patients respectively (mean (SE) actuarial freedom of sinus node dysfunction at four years (81(7)%)). Pacemakers were needed in five (16%) of the 31 patients for insufficient sinus node rhythm at rest only

  3. Modelling Gaucher disease progression: long-term enzyme replacement therapy reduces the incidence of splenectomy and bone complications

    PubMed Central

    2014-01-01

    Long-term complications and associated conditions of type 1 Gaucher Disease (GD) can include splenectomy, bone complications, pulmonary hypertension, Parkinson disease and malignancies. Enzyme replacement therapy (ERT) reverses cytopenia and reduces organomegaly. To study the effects of ERT on long-term complications and associated conditions, the course of Gaucher disease was modelled. The cohort consisted of all diagnosed GD patients in the Netherlands. Mutually exclusive disease states were defined as ‘asymptomatic’, ‘signs/symptoms’, ‘recovery’, ‘splenectomy’, ‘bone complication’, ‘multiple complications’ and ‘malignancy’. A natural history (NH) cohort was delineated based upon historical data on Dutch patients before ERT was available. Cumulative incidence curves were composed for progression from each disease state to the next. Two scenarios were applied for the ERT cohort: time to complications was calculated from A. start of ERT; B. entering the previous disease state. Median time for the development of signs and/or symptoms was 30.1 years (N = 73). In the NH cohort (N = 42), 9% had developed a bone complication after 10 years in the signs/symptoms phase, while 21% had undergone a splenectomy. In the ERT cohort (N = 29 (A), N = 28 (B)), 12% (A) or 4% (B) had developed a bone complication after 10 years in this phase and no patient was splenectomized. No patients in the NH cohort recovered, compared to 50% in the ERT cohort after 3.6 years (N = 28 (A)) or 22.4 years (N = 27 (B)) of treatment. Median time from a first to a second complication was 11 years in the NH cohort (N = 31), whereas 16 respectively 14 percent had developed a second complication after 10 years in the ERT cohort (N = 17, scenario A/B). Fourteen percent (scenario A/B) developed an associated malignancy after 10 years in the phase ‘multiple complications’ (N = 23). Associated malignancies occurred almost exclusively in advanced disease stages, therefore it

    Background and Objectives The aim of the study is to evaluate the long-term results after a surgical repair of Ebstein's anomaly. Subjects and Methods Forty-eight patients with Ebstein's anomaly who underwent open heart surgery between 1982 and 2013 were included. Median age at operation was 5.6 years (1 day-42.1 years). Forty-five patients (93.7%) demonstrated tricuspid valve (TV) regurgitation of less than moderate degree. When the patients were divided according to Carpentier's classification, types A, B, C, and D were 11, 21, 12, and 4 patients, respectively. Regarding the type of surgical treatment, bi-ventricular repair (n=38), one-and-a half ventricular repair (n=5), and single ventricle palliation (n=5) were performed. Of 38 patients who underwent a bi-ventricular repair, TV repairs were performed by Danielson's technique (n=20), Carpentier's technique (n=11), Cone repair (n=4), and TV annuloplasty (n=1). Two patients underwent TV replacement. Surgical treatment strategies were different according to Carpentier's types (p<0.001) and patient's age (p=0.022). Results There were 2 in-hospital mortalities (4.2%; 1 neonate and 1 infant) and 2 late mortalities during follow-up. Freedom from recurrent TV regurgitation rates at 5, 10, and 15 years were 88.6%, 66.3%, 52.7%, respectively. TV regurgitation recurrence did not differ according to surgical method (p=0.800). Survival rates at 5, 10, and 20 years were 95.8%, 95.8%, and 85.6%, respectively, and freedom from reoperation rates at 5, 10, and 15 years were 85.9%, 68.0%, and 55.8%, respectively. Conclusion Surgical treatment strategies were decided according to Carpentier's type and patient's age. Overall survival and freedom from reoperation rates at 10 years were 95.8% and 68.0%, respectively. Approximately 25% of patients required a second operation for TV during the follow-up.

    Background Endoscopic thoracic sympathectomy is currently the best treatment for primary upper extremity hyperhidrosis, but the potential for adverse effects, particularly the development of compensatory sweating, is a concern and often precludes surgery as a definitive therapy. This study aims to evaluate long-term results of two-stage unilateral versus one-stage bilateral thoracoscopic sympathectomy. Methods From November 1995 to February 2011, 261 patients with severe palmar and/or axillary hyperhidrosis underwent endoscopic sympathectomy with a follow-up of at least 4 years. One-hundred and twenty-six patients received one-stage bilateral, single port video-assisted thoracoscopic sympathectomy (one-stage group) and 135 patients underwent two-stage unilateral, single-port video-assisted thoracoscopic sympathectomy, with a mean time interval of four months between the procedures (two-stage group). Results The mean postoperative follow-up period was 7.2 years (range, 4–9 years). Sixteen patients (12.7%) in the one-stage group and 15 patients (11.1%) in the two-stage group suffered from bradycardia (P=0.15). Recurrences occurred in three patients (2.4%) in the one-stage group and one (0.7%) in the two-stage group (P=0,09). Facial flushing or hyperthermia occurred in eight patients (6.3%) in the one-stage group and 11 (8.1%) of the two-stage group. Compensatory sweating occurred in 27 patients (21.4%) in the one-stage group and six patients (4.4%) in the two-stage group (P=0.0001). However, compensatory sweating recovered in five patients (83.3%) in the two-stage group versus nine (33.35%) in one-stage group during the follow-up period (Log-rank test P=0.016; HR, 7.196; 95% CI, 1.431–36.20). An improvement in postoperative quality of life (QoL) scores was observed in at least 90% of patients at three years after surgery in the one-stage group and at least 95% of patients in the two-stage group (P=0.001). Conclusions Compensatory sweating seems to improve during

    Mouse models of Alzheimer’s disease (AD) have been developed to study the pathophysiology of amyloid β protein (Aβ) toxicity, which is thought to cause severe clinical symptoms such as memory impairment in AD patients. However, inconsistencies exist between studies using these animal models, specifically in terms of the effects on synaptic plasticity, a major cellular model of learning and memory. Whereas some studies find impairments in plasticity in these models, others do not. We show that long-term potentiation (LTP), in the CA1 region of hippocampal slices from this mouse, is impared at Tg2576 adult 6–7 months old. However, LTP is inducible again in slices taken from Tg2576 aged 14–19 months old. In the aged Tg2576, we found that the percentage of parvalbumin (PV)-expressing interneurons in hippocampal CA1-3 region is significantly decreased, and LTP inhibition or reversal mediated by NRG1/ErbB signaling, which requires ErbB4 receptors in PV interneurons, is impaired. Inhibition of ErbB receptor kinase in adult Tg2576 restores LTP but impairs depotentiation as shown in aged Tg2576. Our study suggests that hippocampal LTP reemerges in aged Tg2576. However, this reemerged LTP is an insuppressible form due to impaired NRG1/ErbB signaling, possibly through the loss of PV interneurons. PMID:27377368

    Long-term treatment with triethylene tetramine dihydrochloride, (trientine, TETA) was evaluated in 19 patients with Wilson's disease (WD). Two were given the drug as first choice and 17 after treatment with penicillamine. The change was made because of side-effects, lack of improvement or worsening of neurological symptoms. All penicillamine-induced side-effects reverted. Thirteen patients still receive trientine, and the mean total observation time on this treatment is 8.5 years/patient. Seven of the 13 are free from symptoms related to WD, five have mild to moderate neurological symptoms, mainly dysarthria. One patient with neurological symptoms who received trientine from the start of treatment deteriorated rapidly and is now severely dystonic. The symptoms initially worsened and later improved in one patient. All other patients improved during trientine treatment. Three patients died: two from a multifocal cancer including the liver and one non-complier from a ruptured spleen. Two patients underwent liver transplantation for progressive liver failure: one non-complier and one with liver cirrhosis whose liver function deteriorated despite treatment; both are now free from symptoms. Unexpectedly, two patients developed a serious colitis, one with duodenitis as well, that improved after withdrawal of the drug. No other unfavourable effects of trientine were recorded.

    In a previous 52-week trial, treatment with alglucosidase alfa markedly improved cardiomyopathy, ventilatory function, and overall survival among 18 children <7 months old with infantile-onset Pompe disease. Sixteen of the 18 patients enrolled in an extension study, where they continued to receive alglucosidase alfa at either 20 mg/kg biweekly (n=8) or 40 mg/kg biweekly (n=8), for up to a total of 3 years. These children continued to exhibit the benefits of alglucosidase alfa at the age of 36 months. Cox regression analyses showed that over the entire study period, alglucosidase alfa treatment reduced the risk of death by 95%, reduced the risk of invasive ventilation or death by 91%, and reduced the risk of any type of ventilation or death by 87%, as compared to an untreated historical control group. Cardiomyopathy continued to improve and 11 patients learned and sustained substantial motor skills. No significant differences in either safety or efficacy parameters were observed between the 20 mg/kg and 40 mg/kg biweekly doses. Overall, long-term alglucosidase alfa treatment markedly extended survival as well as ventilation-free survival, and improved cardiomyopathy. PMID:19542901

    The recent decline in cardiovascular disease mortality in Western countries has been linked with changes in life style and treatment. This study considers periods of decline before effective medical interventions or knowledge about risk factors. Trends in annual age-standardized death rates from cerebrovascular disease, heart disease and circulatory disease, and all cardiovascular disease are reviewed for three phases, 1881-1916, 1920-1939, and 1940-2000. There was a consistent decline in the cerebrovascular disease death rate between 1891 and 2000, apart from brief increases after the two world wars. The heart disease and circulatory disease death rate was declining between 1891 and 1910 before cigarette smoking became prevalent. The early peak in cardiovascular mortality in 1891 coincided with an influenza pandemic and a peak in the death rate from bronchitis, pneumonia and influenza. There is also correspondence between short-term fluctuations in the death rates from these respiratory diseases and cardiovascular disease. This evidence of ecological association is consistent with the findings of many studies that seasonal influenza can trigger acute myocardial infarction and episodes of respiratory infection are followed by increased risk of cardiovascular events. Vaccination studies could provide more definitive evidence of the role in cardiovascular disease and mortality of influenza, other viruses, and common bacterial agents of respiratory infection.

    Between 1984 and 1986, 54 patients underwent postanal repair for neurogenic faecal incontinence. Forty-two (41 women) were available for follow-up 5-8 (median 6.2) years after operation. Of these, 34 women attended for clinical and anorectal physiological assessment. Anal endosonography was also performed in 30 patients. In the 34 patients examined, continence categories (Browning and Parks' classification) of C (n = 12) and D (n = 22) before surgery became A (n = 2), B (n = 12), C (n = 16) and D (n = 1) at 6 months and A (n = 4), B (n = 5), C (n = 21) and D (n = 4) at 5-8 years. Nine patients therefore had continence for solids and liquids, five of whom were incontinent to flatus, in the long term. Assessment of outcome by patients revealed long-term improvement in 28 and no change in six. Two of the 34 patients assessed were housebound because of incontinence. Of the total of 54 patients, only one required a stoma. The length of the anal canal increased significantly from a preoperative median (range) of 2.0 (1.5-4.0) cm to 3.8 (1.8-5.5) cm 5-8 years after surgery. Perineal descent at rest decreased markedly. Progression of neuromuscular damage was demonstrated by prolongation of the pudendal nerve terminal motor latency from a median (range) 2.38 (1.80-3.35) ms to 2.80 (2.20-4.25) ms and increasing median (range) fibre density in the external sphincter, from 1.86 (1.76-2.40) to 3.63 (2.03-6.20). The pudendal nerve terminal latency was the only preoperative physiological variable that correlated significantly with long-term outcome (A and B 2.20 ms versus C and D 2.65 ms, P < 0.05). At long-term assessment, maximal anal squeeze pressure was the only physiological variable that correlated significantly with clinical outcome. Anal endosonography revealed a clinically undetected sphincter defect in 19 of 30 patients examined but the presence of a defect did not relate to clinical outcome. PMID:8313093

    The purpose of this study was to evaluate the long-term outcome of percutaneous therapy of ureteral complications after renal transplantation. Between January 2000 and June 2006 we percutaneously treated 26 renal transplant patients with ureteral obstruction (n=19) and leak (n=7). Obstructions were classified as early (<2 months after transplantation) or late (>2 months). Patients with leak were treated with nephro-ureteral catheter placement and subsequent double-J stenting. Balloon dilatation, stent placement, and basket extraction were used to treat ureteral obstructions. Patients were followed with ultrasonography. No major procedure-related complication occurred. The mean follow-up time was 34.3 months (range: 6 to 74 months). Initial clinical success was achieved in all 19 patients with obstruction and 6 of 7 patients with leak. Four of 9 early obstructions and 4 of 10 late obstructions recurred during the follow-up. All recurrences were initially managed again with percutaneous methods, including cutting balloon technique and metallic stent placement. Although there was no recurrence in patients with successfully treated leak, stricture was seen at the previous leak site in two patients. These strictures were also successfully managed percutaneously. We conclude that in the treatment of ureteral obstruction and leak following renal transplantation, percutaneous therapy is an effective alternative to surgery. However, further interventions are usually needed to maintain long-term patency.

    Abstract Visual recognition memory is early impaired in Alzheimer's disease. Long-term depression of synaptic transmission in the perirhinal cortex is critically involved in this form of memory. We found that synaptic transmission was impaired in perirhinal cortex slices obtained from 3-month-old Tg2576 mice, and that 3,000 pulses at 5 Hz induced long-term depression in perirhinal cortex slices from age-matched control mice, but not in those from Tg2576 mice. To our knowledge, these data provide the first evidence of synaptic transmission and long-term depression impairment in the perirhinal cortex in an animal model of Alzheimer's disease, and the earliest synaptic deficit in Tg2576 mice.

    Musical memory was tested in Alzheimer patients and in healthy older adults using long-term and short-term memory tasks. Long-term memory (LTM) was tested with a recognition procedure using unfamiliar melodies. Short-term memory (STM) was evaluated with same/different judgment tasks on short series of notes. Musical memory was compared to verbal memory using a task that used pseudowords (LTM) or syllables (STM). Results indicated impaired musical memory in AD patients relative to healthy controls. The deficit was found for both long-term and short-term memory. Furthermore, it was of the same magnitude for both musical and verbal domains whether tested with short-term or long-term memory tasks. No correlation was found between musical and verbal LTM. However, there was a significant correlation between verbal and musical STM in AD participants and healthy older adults, which suggests that the two domains may share common mechanisms.

    Many have proposed that Acceptance and Commitment Therapy (ACT) may be particularly effective for improving outcomes in chronic disease/long-term conditions, and ACT techniques are now being used clinically. However, reviews of ACT in this context are lacking, and the state of evidence is unclear. This systematic review aimed to: collate all ACT interventions with chronic disease/long-term conditions, evaluate their quality, and comment on efficacy. Ovid MEDLINE, EMBASE and Psych Info were searched. Studies with solely mental health or chronic pain populations were excluded. Study quality was then rated, with a proportion re-rated by a second researcher. Eighteen studies were included: eight were randomised controlled trials (RCTs), four used pre-post designs, and six were case studies. A broad range of applications was observed (e.g. improving quality of life and symptom control, reducing distress) across many diseases/conditions (e.g. HIV, cancer, epilepsy). However, study quality was generally low, and many interventions were of low intensity. The small number of RCTs per application and lower study quality emphasise that ACT is not yet a well-established intervention for chronic disease/long-term conditions. However, there was some promising data supporting certain applications: parenting of children with long-term conditions, seizure-control in epilepsy, psychological flexibility, and possibly disease self-management.

    Cryoanalgesia (the use of cold to provide anesthesia or analgesia) is the oldest anesthetic and analgesic still in current clinical use. Its intraoperative use in providing postoperative analgesia for acute thoracic pain problems via an open thoracotomy is well described. The long-term efficacy of cryoanalgesia for the management of chronic thoracic pain due to intercostal neuralgia is less clear. We retrospectively examined the medical records of patients who received percutaneous cryoanalgesia following successful intercostal nerve blockade for chronic chest pain. Sixty percent of the patients (N = 43) reported significant pain relief immediately following their procedure. Three months following cryoanalgesia, 50% continued to report significant pain relief. There were no reports of neuritis or neuroma formation and only three patients had a pneumothorax. This work provides evidence that cryoanalgesia is a safe and efficacious method of providing analgesia for chronic thoracic pain due to intercostal neuralgia. PMID:12152929

    In situ vitrification (ISV) is an emerging technology for the remediation of hazardous and radioactive waste sites. The concept relies on the principle of Joule heating to raise the temperature of a soil between an array of electrodes above the melting temperature. After cooling, the melt solidifies into a massive glass and crystalline block similar to naturally occurring obsidian. Determining the long-term performance of ISV products in a changing regulatory environment requires a fundamental understanding of the mechanisms controlling the dissolution behavior of the material. A series of experiments was performed to determine the dissolution behavior of samples produced from the ISV processing of typical soils from the Idaho National Engineering Laboratory subsurface disposal area. Dissolution rate constant measurements were completed at 90{degrees}C over the pH range 2 to 11 for one sample obtained from a field test of the ISV process.

    This report demonstrates the role of epidemiologic surveillance and investigation in the control of infectious diseases in a long-term refugee camp. The applications of simple epidemiologic methods in a refugee camp on the Thai-Cambodian border are described for a one-year period. The development of a Health Information Office facilitated the collection of demographic and vital statistics data, administration of a disease surveillance system, regular monitoring of hospital and outpatient discharge diagnoses, and investigation of disease outbreaks. This office also organized community health education campaigns and disease control efforts. Examples of specific disease investigations are provided to demonstrate the utility of epidemiologic surveillance in the control of infectious disease. We conclude that simple epidemiologic methods play an important role in health planning in long-term refugee camps. PMID:2356906

    In clinical practice, the combination of congenital heart disease (CHD) with malformations of other organs occurs in about 10 % of cases, including chromosomal disease with heart defects, which are observed mainly with certain syndromes. In the Bakoulev SCCS (Moscow, Russian Federation), from 01.2005 to 01.2011, complete atrioventricular septal defect (CAVSD) repair was performed on 163 patients (5.6 ± 3.0 months) with Down Syndrome (DS) using the single-patch (n = 40) and the two-patch (n = 123) methods. The control group consisted of 214 infants aged 6.49 ± 3.03 months with CAVSD and normal karyotype. A retrospective cohort study was made, as well as a comparative analysis of the immediate (up to 30 days) and long-term (12-75 months, at the average of 56 ± 15) results of the repair of CAVSD in infants with DSand normal karyotype/chromosome set (NK). During the hospital treatment period, we registered the following complications: pulmonary hypertensive crises in 6 % (n = 9) of patients with DS and in 10 % (n = 21) of infants with NK, infectious complications in 21% (n = 34) of patients with DS and in 8% (n = 17) of infants with NK. Squeal structures in groups were differentiated. The doses and duration of cardiotonic support in the NK patients were significantly higher in comparison with the DS patients (7.5 ± 2.1 days vs 3.4 ± 1.15 days, p < 0.05). Respiratory infections on the background of immunodeficiency were found more often in the DS group (21% in DS vs 8% in NK, p < 0.05), demanding higher postoperative pulmonary ventilation time in DS patients in comparison with normal infants was required (DS 5.1 ± 2.8 days vs NK 1.7 ± 0.8 days, p < 0.05). In DS infants, abnormalities of the left AV valve (doubling of the mitral valve, single papillary muscle, closely spaced groups of papillary muscles, leaflet or chordal dysplasia, hypoplastic valve ring) occur as statistically significant (8% DS vs 12% NK; p < 0.05) which is rarer than in children having the

    Chemistry-climate models attempt to bring together our best knowledge of the key processes that govern the composition of the atmosphere and its response to changes in forcing. We test these models on a process by process basis by comparing model results to data from many sources. A more difficult task is testing the model response to changes. One way to do this is to use the natural and anthropogenic experiments that have been done on the atmosphere and are continuing to be done. These include the volcanic eruptions of El Chichon and Pinatubo, the solar cycle, and the injection of chlorine and bromine from CFCs and methyl bromide. The test of the model's response to these experiments is their ability to produce the long-term variations in ozone and the trace gases that affect ozone. We now have more than 25 years of satellite ozone data. We have more than 15 years of satellite and ground-based data of HC1, HN03, and many other gases. I will discuss the testing of models using long-term satellite data sets, long-term measurements from the Network for Detection of Stratospheric Change (NDSC) , long-term ground-based measurements of ozone.

    2015-01-01

    Objectives We evaluate the long-term surgical and hearing results using a canal wall down mastoidectomy technique followed by cavities obliteration, canal wall reconstruction and ossiculoplasty without staging. Methods A total of 44 patients between January 2002 and October 2009 were selected and 27 of them were revision cases. Preoperative and postoperative pure tone average (PTA) and air-bone gap (ABG) were assessed and compared 1 and 4 years after surgery. Results The middle ear was well healed and aerated in 40 patients (90.9%) and the tympanic membrane was intact in 42 patients (95.5%). Recurrent cholesteatoma was found on postoperative follow-up in two of the revision patients (7.4%) but none in the primary patients. Seven patients were found to have partial canal bone absorption, but revision surgery was not required. Over 86.4% of all cases were water resistant. Long-lasting improvement and/or preservation of hearing, with maintenance of PTA-ABG closure in 63.7% of all cases within 20 dB, were obtained. Conclusion The efficacy of our technique after a canal wall down mastoidectomy is satisfactory, and the rate of complication is acceptably low. We believe that our technique could be a convenient method in disease control and providing an excellent basis for hearing restoration simultaneously. PMID:26330917

    Cochlear implantation through the standard posterior tympanotomy approach may sometimes be challenging. In cases with complicated anatomy or malformations, an alternative surgical technique may be chosen. The transattical approach is a simple technique based on a mastoidectomy and a transmeatal cochleostomy. The electrode is driven to the middle ear through the attic. This way it overcomes some of the standard technique's drawbacks. Our aim is to assess the value of this alternative approach in cochlear implant surgery. We conducted a comparative retrospective study; we included 74 patients operated by transattical approach and 59 patients operated with the standard technique. Auditory performance and complications at long term follow-up were compared. The consequences of the different trajectory of the electrode in the transattical approach were also studied. No significant differences were found between both groups regarding complication rates and cochlear implant performance. The electrode's integrity was not significantly affected by its different position and angles, when compared to the standard approach. We conclude that transattical approach is a safe technique for cochlear implantation. It may be considered as an alternative to the posterior tympanotomy approach for those cases where this cannot be performed. PMID:24292213

    Objective To examine the long-term relationship between changes in water and beverage intake and weight change. Subjects Prospective cohort studies of 50 013 women aged 40-64 in the Nurses’ Health Study (NHS, 1986-2006), 52 987 women aged 27-44 in the NHS II (1991-2007), and 21 988 men aged 40-64 in the Health Professionals Follow-up Study (1986-2006) without obesity and chronic diseases at baseline. Measures We assessed the association of weight change within each 4-year interval with changes in beverage intakes and other lifestyle behaviors during the same period. Multivariate linear regression with robust variance and accounting for within-person repeated measures were used to evaluate the association. Results across the three cohorts were pooled by an inverse-variance-weighted meta-analysis. Results Participants gained an average of 1.45 kg (5th to 95th percentile, −1.87 to 5.46) within each 4-year period. After controlling for age, baseline body mass index, and changes in other lifestyle behaviors (diet, smoking habits, exercise, alcohol, sleep duration, TV watching), each 1-cup/d increment of water intake was inversely associated with weight gain within each 4-year period (−0.13 kg; 95% CI: −0.17, −0.08). The associations for other beverages were: SSBs (0.36 kg; 0.24, 0.48), fruit juice (0.22 kg; 0.15, 0.28), coffee (−0.14 kg; −0.19, −0.09), tea (−0.03 kg; −0.05, −0.01), diet beverages (−0.10 kg; −0.14, −0.06), low-fat milk (0.02 kg; −0.04, 0.09), and whole milk (0.02 kg; −0.06, 0.10). We estimated that replacement of 1 serving/d of SSBs by 1 cup/d of water was associated with 0.49 kg (95% CI: 0.32, 0.65) less weight gain over each 4-year period, and the replacement estimate of fruit juices by water was 0.35 kg (95% CI: 0.23, 0.46). Substitution of SSBs or fruit juices by other beverages (coffee, tea, diet beverages, low-fat and whole milk) were all significantly and inversely associated with weight gain. Conclusion Our results

    Abstract To assess prognostic benefits of intraoperative electron beam radiation therapy (IOERT) in patients with nonmetastatic locally advanced pancreatic cancer (LAPC) and evaluate optimal adjuvant treatment after IOERT. A retrospective cohort study using prospectively collected data was conducted at the Cancer Hospital of the Chinese Academy of Medical Sciences, China National Cancer Center. Two hundred forty-seven consecutive patients with nonmetastatic LAPC who underwent IOERT between January 2008 and May 2015 were identified and included in the study. Overall survival (OS) was calculated from the day of IOERT. Prognostic factors were examined using Cox proportional hazards models. The 1-, 2-, and 3-year actuarial survival rates were 40%, 14%, and 7.2%, respectively, with a median OS of 9.0 months. On multivariate analysis, an IOERT applicator diameter < 6 cm (hazards ratio [HR], 0.67; 95% confidence interval [CI], 0.47–0.97), no intraoperative interstitial sustained-release 5-fluorouracil chemotherapy (HR, 0.46; 95% CI, 0.32–0.66), and receipt of postoperative chemoradiotherapy followed by chemotherapy (HR, 0.11; 95% CI, 0.04–0.25) were significantly associated with improved OS. Pain relief after IOERT was achieved in 111 of the 117 patients, with complete remission in 74 and partial remission in 37. Postoperative complications rate and mortality were 14.0% and 0.4%, respectively. Nonmetastatic LAPC patients with smaller size tumors could achieve positive long-term survival outcomes with a treatment strategy incorporating IOERT and postoperative adjuvant treatment. Chemoradiotherapy followed by chemotherapy might be a recommended adjuvant treatment strategy for well-selected cases. Intraoperative interstitial sustained-release 5-fluorouracil chemotherapy should not be recommended for patients with nonmetastatic LAPC. PMID:27661028

    The effects of harvest intensity (sawlog, SAW; whole tree, WTH; and complete tree, CTH) on biomass and soil C were studied in four forested sites in the southeastern US (mixed deciduous forests at Oak Ridge, TN and Coweeta, NC; Pinus taeda at Clemson, SC: and P. eliottii at Bradford, FL). In general, harvesting had no lasting effects on soil C. However, intensive temporal sampling at the NC and SC sites revealed short-term changes in soil C during the first few years after harvesting, and large, long-term increases in soil C were noted at the TN site in all treatments. Thus, changes in soil C were found even though lasting effects of harvest treatment were not. There were substantial differences in growth and biomass C responses to harvest treatments among sites. At the TN site, there were no differences in biomass at 15 years after harvest. At the SC site, greater biomass was found in the SAW than in the WTH treatment 16 years after harvest, and this effect is attributed to be due to both the N left on site in foliar residues and to the enhancement of soil physical and chemical properties by residues. At the FL site, greater biomass was found in the CTH than in the WTH treatment 15 years after harvest, and this effect is attributed to be due to differences in understory competition. Biomass data were not reported for NC. The effects of harvest treatment on ecosystem C are expected to magnify over time at the SC and FL sites as live biomass increases, whereas the current differences in ecosystem C at the TN site (which are due to the presence of undecomposed residues) are expected to lessen with time.

    Purpose: To evaluate the efficacy of conformal external beam radiotherapy (RT) for local control of progressive airway amyloidosis. Methods and Materials: We conducted a retrospective review of patients with biopsy-proven progressive airway amyloidosis treated with conformal RT between 2000 and 2006 at Boston Medical Center. The patients were evaluated for performance status and pulmonary function, with computed tomography and endoscopy after RT compared with the pretreatment studies. Local control was defined as the lack of progression of airway wall thickening on computed tomography imaging and stable endobronchial deposits by endoscopy. Results: A total of 10 symptomatic airway amyloidosis patients (3 laryngeal and 7 tracheobronchial) received RT to a median total dose of 20 Gy in 10 fractions within 2 weeks. At a median follow-up of 6.7 years (range, 1.5-10.3), 8 of the 10 patients had local control. The remaining 2 patients underwent repeat RT 6 and 8.4 months after initial RT, 1 for persistent bronchial obstruction and 1 for progression of subglottic amyloid disease with subsequent disease control. The Eastern Cooperative Oncology Group performance status improved at a median of 18 months after RT compared with the baseline values, from a median score of 2 to a median of 1 (p = .035). Airflow (forced expiratory volume in 1 second) measurements increased compared with the baseline values at each follow-up evaluation, reaching a 10.7% increase (p = .087) at the last testing (median duration, 64.8 months). Acute toxicity was limited to Grade 1-2 esophagitis, occurring in 40% of patients. No late toxicity was observed. Conclusions: RT prevented progressive amyloid deposition in 8 of 10 patients, resulting in a marginally increased forced expiratory volume in 1 second, and improved functional capacity, without late morbidity.

    Purpose this study was conducted to evaluate long-term results following treatment of chronic lateral ankle instability using the Broström-Gould technique in athletes. Methods eighteen athletes involved in competitive sports at different levels, who suffered from chronic lateral ankle instability, underwent Broström-Gould ligamentoplasty between 2000 and 2005. The results of the surgery were evaluated using the American Orthopaedic Foot and Ankle Society (AOFAS) scale. Results the results at 10–15 years of follow-up were excellent in 94.5% of these cases and good in the remaining 5.5%. An increase of 31.2 points in the AOFAS scale score was recorded at follow-up (with the score rising to 98.8, from 67.6 preoperatively). All the athletes returned to their respective sports at the same level as prior to the surgery. Imaging at long-term follow-up showed no signs of arthritic degeneration. Conclusions the results of this study show that the Broström-Gould technique is an effective procedure for the treatment of chronic lateral ankle instability in the athlete, giving excellent long-term results. Level of evidence therapeutic case series, level IV.

    2013-01-01

    Long-term non-progressors (LTNP) were identified after 10–15 years of the epidemic, and have been the subject of intense investigation ever since. In a small minority of cases, infection with nef/3′LTR deleted attenuated viral strains allowed control over viral replication. A common feature of LTNP is the readily detected proliferation of CD4 T-cells in vitro, in response to p24. In some cases, the responding CD4 T-cells have cytotoxic effector function and may target conserved p24 epitopes, similar to the CD8 T-cells described below. LTNP may also carry much lower HIV DNA burden in key CD4 subsets, presumably resulting from lower viral replication during primary infection. Some studies, but not others, suggest that LTNP have CD4 T-cells that are relatively resistant to HIV infection in vitro. One possible mechanism may involve up-regulation of the cell cycle regulator p21/waf in CD4 T-cells from LTNP. Delayed progression in Caucasian LTNP is also partly associated with heterozygosity of the Δ32 CCR5 allele, probably through decreased expression of CCR5 co-receptor on CD4 T-cells. However, in approximately half of Caucasian LTNP, two host genotypes, namely HLA-B57 and HLA-B27, are associated with viral control. Immunodominant CD8 T-cells from these individuals target epitopes in p24 that are highly conserved, and escape mutations have significant fitness costs to the virus. Furthermore, recent studies have suggested that these CD8 T-cells from LTNP, but not from HLA-B27 or HLA-B57 progressors, can cross-react with intermediate escape mutations, preventing full escape via compensatory mutations. Humoral immunity appears to play little part in LTNP subjects, since broadly neutralizing antibodies are rare, even amongst slow progressors. Recent genome-wide comparisons between LTNP and progressors have confirmed the HLA-B57, HLA-B27, and delta32 CCR5 allelic associations, plus indicated a role for HLA-C/KIR interactions, but have not revealed any new genotypes so

    Curettage and filling with acrylic cement in the treatment of para-articular giant cell tumor (GCT) has multiple advantages as compared to other methods; nonetheless, the possibility of progression in arthrosis is still a drawback. The literature does not report long-term functional results when this method was used. Four cases are presented with a mean long-term follow-up of 13.5 years (minimum 11, maximum 18). Clinical results, evaluated by the Enneking system (18), were excellent, and there were no radiological modifications, so that we believe that this is the method to choose for Campanacci stage I and II GCT (1), and in some stage III cases, as joint function is not compromised in time.

    A 69-year-old man had undergone left ureteronephrectomy because of a left renal pelvic tumor, however the pathological diagnosis was inflammatory pseudotumor. About 1 year later, computed tomography showed a mass at the right kidney near the hilar. Ureterorenoscopy and urine cytology were performed, and their results showed no evidence of malignancy. He had been followed closely without therapy. The mass increased in size during follow-up, and we reviewed the surgical specimen of the left ureteronephrectomy. Immunohistochemical studies revealed diffuse infiltration by IgG4 positive plasma cell. His serum IgG4 was high. We diagnosed him as IgG4-related kidney disease. In response to treatment with corticosteroid, the size of the tumor and serum IgG4 levels decreased. Most reported cases of IgG4-related disease involving kidney have a history of prior pancreatic involvement. We report a rare long term follow-up case of IgG4-related kidney disease without pancreatic involvement. PMID:24908817

    Purpose: We report the long-term results of a prospective, Phase II study of long-term androgen deprivation (AD), pelvic radiotherapy (EBRT), permanent transperineal prostate brachytherapy boost (PB), and adjuvant docetaxel in patients with high-risk prostate cancer. Methods and Materials: Eligibility included biopsy-proven prostate adenocarcinoma with the following: prostate-specific antigen (PSA) > 20 ng/ml; or Gleason score of 7 and a PSA >10 ng/ml; or any Gleason score of 8 to 10; or stage T2b to T3 irrespective of Gleason score or PSA. Treatment consisted of 45 Gy of pelvic EBRT, followed 1 month later by PB with either iodine-125 or Pd-103. One month after PB, patients received three cycles of docetaxel chemotherapy (35 mg/m{sup 2} per week, Days 1, 8, and 15 every 28 days). All patients received 2 years of AD. Biochemical failure was defined as per the Phoenix definition (PSA nadir + 2). Results: From August 2000 to March 2004, 42 patients were enrolled. The median overall and active follow-ups were 5.6 years (range, 0.9-7.8 years) and 6.3 years (range, 4-7.8 years), respectively. Grade 2 and 3 acute genitourinary (GU) and gastrointestinal (GI) toxicities were 50.0% and 14.2%, respectively, with no Grade 4 toxicities noted. Grade 3 and 4 acute hematologic toxicities were 19% and 2.4%, respectively. Of the patients, 85.7% were able to complete the planned multimodality treatment. The 5- and 7-year actuarial freedom from biochemical failures rates were 89.6% and 86.5%, and corresponding rates for disease-free survival were 76.2% and 70.4%, respectively. The 5- and 7-year actuarial overall survival rates were 83.3% and 80.1%, respectively. The 5- and 7-year actuarial rates of late Grade 2 GI/GU toxicity (no Grade 3-5) was 7.7%. Conclusions: The trimodality approach of using 2 years of AD, external radiation, brachytherapy, and upfront docetaxel in high-risk prostate cancer is well tolerated, produces encouraging long-term results, and should be validated in a

    The purpose of the research was to study effect of long-term isolation on night sleep. The data were collected during international ground simulation of an interplanetary manned flight--"Mars-500". The polysomnographic recordings of six healthy men were performed before, four times during and after 520-days confinement. During the isolation sleep efficiency and delta-latency decreased, while sleep latency increased. Post-hoc analysis demonstrate significant differences between background and the last (1.5 months before the end of the experiment) measure during isolation. Frequency of nights with low sleep efficiency rose on the eve of the important for the crew events (simulation of Mars landing and the end of the confinement). Two weeks after the landing simulation, amount of the nights with a low sleep efficiency significantly decreased. Therefore, anticipation of significant event under condition of long-term isolation might result in sleep worsening in previously healthy men, predominantly difficulties getting to sleep.

    Objective Long-term exposure to traffic-related air pollution has been linked to increased risk of obesity and diabetes and may be associated with higher serum levels of the adipokine leptin, but this hypothesis has not been previously evaluated in humans. Methods In a cohort of older adults, we estimated the association between serum leptin concentrations and two markers of long-term exposure to traffic pollution, adjusting for participant characteristics, temporal trends, socioeconomic factors, and medical history. Results An interquartile range increase (0.11 µg/m3) in annual mean residential black carbon was associated with 12% (95% CI: 3%, 22%) higher leptin levels. Leptin levels were not associated with residential distance to major roadway. Conculsions If confirmed, these findings support the emerging evidence suggesting that certain sources of traffic pollution may be associated with adverse cardiometabolic effects. PMID:25192230

    The first epidemiological studies showing a link between low birth weight and chronic diseases in adults did not distinguish the origins of low birth weight. A low birth weight may be the result of a premature birth. It can also be caused by an intrauterine growth restriction (IUGR). A child can be both preterm and IUGR. It is clear now that prematurity is an independent risk factor for programming chronic adult diseases. However, unlike adults born IUGR, adults born prematurely do not have an increased risk to develop metabolic syndrome (dyslipidemia or obesity). An increased risk of neurodevelopmental and psychiatric morbidity and hypertension is found after a premature birth. Mechanisms of chronic diseases programming are multiple: they involve both the cause of prematurity and IUGR such as infection / inflammation or placental insufficiency, but also consequences for therapeutic or nutritional strategies needed to support these children. This chapter describes the possible prevention of perinatal programming of noncommunicable diseases. PMID:26850610

    The loaded disk culture system is an intervertebral disk (IVD)-oriented bioreactor developed by the VU Medical Center (VUmc, Amsterdam, The Netherlands), which has the capacity of maintaining up to 12 IVDs in culture, for approximately 3 weeks after extraction. Using this system, eight goat IVDs were provided with the essential nutrients and submitted to compression tests without losing their biomechanical and physiological properties, for 22 days. Based on previous reports (Paul et al., 2012, 2013; Detiger et al., 2013), four of these IVDs were kept in physiological condition (control) and the other four were previously injected with chondroitinase ABC (CABC), in order to promote degenerative disk disease (DDD). The loading profile intercalated 16 h of activity loading with 8 h of loading recovery to express the standard circadian variations. The displacement behavior of these eight IVDs along the first 2 days of the experiment was numerically reproduced, using an IVD osmo-poro-hyper-viscoelastic and fiber-reinforced finite element (FE) model. The simulations were run on a custom FE solver (Castro et al., 2014). The analysis of the experimental results allowed concluding that the effect of the CABC injection was only significant in two of the four IVDs. The four control IVDs showed no signs of degeneration, as expected. In what concerns to the numerical simulations, the IVD FE model was able to reproduce the generic behavior of the two groups of goat IVDs (control and injected). However, some discrepancies were still noticed on the comparison between the injected IVDs and the numerical simulations, namely on the recovery periods. This may be justified by the complexity of the pathways for DDD, associated with the multiplicity of physiological responses to each direct or indirect stimulus. Nevertheless, one could conclude that ligaments, muscles, and IVD covering membranes could be added to the FE model, in order to improve its accuracy and properly

    Developmental exposure to methamphetamine (MA) causes long-term behavioral and cognitive deficits. One pathway through which MA might induce these deficits is by elevating glucocorticoid levels. Glucocorticoid overexposure during brain development can lead to long-term disruptions in the hypothalamic-pituitary-adrenal (HPA) axis. These disruptions affect the regulation of stress responses and may contribute to behavioral and cognitive deficits reported following developmental MA exposure. Furthermore, alterations in proteins associated with the HPA axis, including vasopressin, oxytocin, and glucocorticoid receptors (GR), are correlated with disruptions in mood and cognition. We therefore hypothesized that early MA exposure will result in short- and long-term alterations in the expression of HPA axis-associated proteins. Male mice were treated with MA (5 mg/kg daily) or Saline from postnatal day (P) 11–20. At P20 and P90, mice were perfused and their brains processed for vasopressin, oxytocin, and GR-immunoreactivity within HPA axis-associated regions. At P20, there was a significant decrease in the number of vasopressin-immunoreactive cells and area occupied by vasopressin-immunoreactiviy in the paraventricular nucleus (PVN) of MA-treated mice, but no difference in oxytocin-immunoreactivity in the PVN, or GR-immunoreactivity in the hippocampus or PVN. In the central nucleus of the amygdala, area occupied by GR-immunoreactivity was decreased by MA. At P90, the number of vasopressin-immunoreactive cells was still decreased, but the area occupied by vasopressin-immunoreactivity no longer differed from Saline controls. No effects of MA were found on oxytocin or GR-immunoreactivity at P90. Thus developmental MA exposure has short- and long-term effects on vasopressin-immunoreactivity and short-term effects on GR-immunoreactivity. PMID:23860125

    Animal studies suggest that hypertension leads to cardiac tissue hypothyroidism, a condition that can by itself lead to heart failure. We have previously shown that short-term thyroid hormone treatment in Spontaneously Hypertensive Heart Failure (SHHF) rats near heart failure is beneficial. This study tested the hypothesis that therapeutic, long-term T3 treatment in SHHF rats can prevent or attenuate cardiac dysfunction. Female SHHF rats were treated orally with a physiological T3 dose (0.04 μg/ml) from 12 to 24 mo of age. Age-matched female SHHF and Wistar-Kyoto rats served as hypertensive and normotensive controls, respectively. SHHF rats had reduced serum free thyroid hormone levels and cardiac tissue T3 levels, LV dysfunction, and elevated LV collagen content compared with normotensive controls. Restoration of serum and cardiac tissue thyroid hormone levels in T3-treated rats was associated with no change in heart rate, but strong trends for improvement in LV systolic function and collagen levels. For instance, end-systolic diameter, fractional shortening, systolic wall stress, and LV collagen levels were no longer significantly different from controls. In conclusion, longstanding hypertension in rats led to chronic low serum and cardiac tissue thyroid hormone levels. Long-term treatment with low-dose T3 was safe. While cardiac dysfunction could not be completely prevented in the absence of antihypertensive treatment, T3 may offer additional benefits as an adjunct therapy with possible improvement in diastolic function.

    The treatment of chronic inflammatory skin disease is associated with the use of topical corticosteroids. Their efficacy, tolerability and adverse effects depend on several factors, specifically potency, type of preparation, extemporaneous dilutions, quantity used, magnitude of the treated body surface, frequency of application, location, patient age, method of application and condition of the skin barrier. We report on two men suffering from chronic inflammatory skin disease, who presented with fatigue and cushingoid appearance after prolonged self-application of potent corticosteroids. Impairment of the skin barrier due to their underlying skin disease, frequent self-application of topical steroids and repeated application of the entire body led to extensive absorption of these substances, eventually culminating in the suppression of the pituitary-hypothalamic-adrenal axis. In conclusion, topical corticosteroids are effective and well-established therapeutic modalities. However, inappropriate use of topical corticosteroids can cause side effects. PMID:24751677

    Objective To evaluate the impact on wound healing and long-term clinical outcomes of endovascular revascularization in patients with critical limb ischemia (CLI). Materials and Methods This is a retrospective study on 189 limbs with CLI treated with endovascular revascularization between 2008 and 2010 and followed for a mean 21 months. Angiographic outcome was graded to technical success (TS), partial failure (PF) and complete technical failure. The impact on wound healing of revascularization was assessed with univariate analysis and multivariate logistic regression models. Analysis of long-term event-free limb survival, and limb salvage rate (LSR) was performed by Kaplan-Meier method. Results TS was achieved in 89% of treated limbs, whereas PF and CF were achieved in 9% and 2% of the limbs, respectively. Major complications occurred in 6% of treated limbs. The 30-day mortality was 2%. Wound healing was successful in 85% and failed in 15%. Impact of angiographic outcome on wound healing was statistically significant. The event-free limb survival was 79.3% and 69.5% at 1- and 3-years, respectively. The LSR was 94.8% and 92.0% at 1- and 3-years, respectively. Conclusion Endovascular revascularization improve wound healing rate and provide good long-term LSRs in CLI. PMID:23690709

    Bowen's disease (BD) is a form of intraepidermal squamous cell carcinoma, which is clinically characterized by gradually enlarging, well-demarcated erythematous plaques with irregular borders and surface crusting or scaling, affecting primarily the elderly. BD often presents with lesions difficult to treat with standard therapy as surgery, cryosurgery, or 5-fluorouracil (5-FU) for the risk of significantly poor cosmetic outcome, failure rate, and adverse events, related mainly to the age of the patients. Topical PDT with methyl aminolevulinate (MAL) represents a valid and approved therapy for BD lesions in many cases, especially for lesions located at poor healing sites or for large patches of disease, due to its high efficacy coupled with good tolerability and tissue-sparing attitude. In this study, we sought to investigate the efficacy, safety, and cosmetic outcome of MAL-PDT in a series of patients with BD lesions which were challenging to treat for clinical, surgical, and patient-related reasons, such as size of the lesion, difficult surgical approach for anatomical sites, or age of patients and request of the best cosmetic result. We also performed a long-term follow-up to assess recurrence rates and eventual late-onset adverse events.

    The circadian clock in peripheral tissues can be entrained by restricted feeding (RF), a regimen that restricts the duration of food availability with no calorie restriction (CR). However, it is not known whether RF can delay the occurrence of age-associated changes similar to CR. We measured circadian expression of clock genes, disease marker genes, metabolic factors and inflammatory and allergy markers in mouse serum, liver, jejunum and white adipose tissue (WAT) after long-term RF of 4 months. We found that circadian rhythmicity is more robust and is phase advanced in most of the genes and proteins tested under RF. In addition, average daily levels of some disease and inflammatory markers were reduced under RF, including liver Il-6 mRNA, tumour necrosis factor (TNF)-α and nuclear factor κB (NF-κB) protein; jejunum Arginase, Afp, Gadd45β, Il-1α and Il-1β mRNA, and interleukin (IL)-6 and TNF-α protein and WAT Il-6, Il-1β, Tnfα and Nfκb mRNA. In contrast, the anti-inflammatory cytokine Il-10 mRNA increased in the liver and jejunum. Our results suggest that RF may share some benefits with those of CR. As RF is a less harsh regimen to follow than CR, the data suggest it could be proposed for individuals seeking to improve their health.

    Thiazolidinediones (TZDs) are agonists at peroxisome proliferator-activated gamma-type (PPAR-γ) receptors and are used clinically for the treatment of type 2 diabetes where they have been shown to reestablish insulin sensitivity, improve lipid profiles, and reduce inflammation. Recent work also suggests that TZDs may be beneficial in Alzheimer’s disease (AD), ameliorating cognitive decline early in the disease process. However, there have been only a few studies identifying mechanisms through which cognitive benefits may be exerted. Starting at 10 months of age, the triple transgenic mouse model of AD (3×Tg-AD) with accelerated amyloid-β (Aβ) deposition and tau pathology was treated with the TZD pioglitazone (PIO-Actos®) at 18 mg/Kg body weight/day. After four months, PIO-treated animals showed multiple beneficial effects, including improved learning on the active avoidance task, reduced serum cholesterol, decreased hippocampal amyloid-β and tau deposits, and enhanced short- and long-term plasticity. Electrophysiological membrane properties and post-treatment blood glucose levels were unchanged by PIO. Gene microarray analyses of hippocampal tissue identified predicted transcriptional responses following TZD treatment as well as potentially novel targets of TZDs, including facilitation of estrogenic processes and decreases in glutamatergic and lipid metabolic/cholesterol dependent processes. Taken together, these results confirm prior animal studies showing that TZDs can ameliorate cognitive deficits associated with AD-related pathology, but also extend these findings by pointing to novel molecular targets in the brain.

    Abstract Background: Erdheim–Chester disease (ECD) is a rare form of non-Langerhans cell histiocytosis. This inflammatory myeloid neoplasm is frequently complicated by neurological symptoms, but stroke is an exceptional manifestation of this disease. Methods: We report the case of a 59-year-old woman who presented a vertebrobasilar stroke secondary to infiltration and severe stenosis of the basilar artery, improved after interferon-alpha therapy. We performed a review of the relevant literature and reported the few other cases described. Results: With our patient, we have found only 7 observations of cerebrovascular disorder in ECD. Most of them had supravascular arteries involvement. Conclusion: Stroke is a rare treatable and potentially reversible complication of ECD. The pathophysiological processes explaining stroke in this disease are uncertain, but periarterial stenosis of cerebral arteries may be a mechanism. PMID:27603396

    Idiopathic Nephrotic Syndrome (INS) was defined as combination of a nephrotic syndrome and non-specific histological abnormalities of the kidney. Among these abnormalities, minimal change nephrotic syndrome (MCNS) is the most common. We report our experience with MCNS; its clinical course, treatments and outcomes. One-hundred twenty children (66 male, 54 female) with MCNS, admitted to Nephrology Department between 1987-2009 was assessed. Their clinical presentations, treatment and disease courses were reviewed. The mean duration of follow-up was 11.5 ± 1.9 years. Initially, all patients given prednisone 2 mg/kg/ day single dose per four weeks a followed by eight weeks of the same daily dose given every other day. After week 12, prednisone was progressively tapered off at the rate of 0.5 mg/kg per 15 daily intervals until complete discontinuation had been achieved by week 16. Steroid resistance was accepted as no achievement of remission following four weeks of prednisone 2 mg/kg/day followed by three intravenous pulses of corticosteroids. At the end of the initial steroid treatment, 106 (88.3%) patients were determinate steroid responsive while 14 (11.7%) patients were steroid resistance. Thirty-eight patients underwent biopsy. At the end of study recovery rate was increased from 88.3% to 94.1%. In conclusion, most of patients entered remission by our therapy end of follow up time. With the support of our satisfactory results among the whole study group, long-term prednisolone treatment still remains valid. PMID:26313331

    Ibrutinib, an oral inhibitor of Bruton tyrosine kinase, is approved for patients with mantle cell lymphoma (MCL) who have received one prior therapy. We report the updated safety and efficacy results from the multicenter, open-label phase 2 registration trial of ibrutinib (median 26.7-month follow-up). Patients (N = 111) received oral ibrutinib 560 mg once daily, and those with stable disease or better could enter a long-term extension study. The primary end point was overall response rate (ORR). The median patient age was 68 years (range, 40-84), with a median of 3 prior therapies (range, 1-5). The median treatment duration was 8.3 months; 46% of patients were treated for >12 months, and 22% were treated for ≥2 years. The ORR was 67% (23% complete response), with a median duration of response of 17.5 months. The 24-month progression-free survival and overall survival rates were 31% (95% confidence interval [CI], 22.3-40.4) and 47% (95% CI, 37.1-56.9), respectively. The most common adverse events (AEs) in >30% of patients included diarrhea (54%), fatigue (50%), nausea (33%), and dyspnea (32%). The most frequent grade ≥3 infections included pneumonia (8%), urinary tract infection (4%), and cellulitis (3%). Grade ≥3 bleeding events in ≥2% of patients were hematuria (2%) and subdural hematoma (2%). Common all-grade hematologic AEs were thrombocytopenia (22%), neutropenia (19%), and anemia (18%). The prevalence of infection, diarrhea, and bleeding was highest for the first 6 months of therapy and less thereafter. With longer follow-up, ibrutinib continues to demonstrate durable responses and favorable safety in relapsed/refractory MCL. The trial is registered to www.ClinicalTrials.gov as #NCT01236391.

    Malnutrition is a major contributor to mortality and is increasingly recognized as a cause of potentially lifelong functional disability. Yet, a rate-limiting step in achieving normal nutrition may be impaired absorptive function due to multiple repeated enteric infections. This is especially problematic in children whose diets are marginal. In malnourished individuals, the infections are even more devastating. This review documents the evidence that intestinal infections lead to malnutrition and that malnutrition worsens intestinal infections. The clinical data presented here derive largely from long-term cohort studies that are supported by controlled animal studies. Also reviewed are the mechanisms by which enteric infections lead to undernutrition and by which malnutrition worsens enteric infections, with implications for potential novel interventions. Further intervention studies are needed to document the relevance of these mechanisms and, most importantly, to interrupt the vicious diarrhea-malnutrition cycle so children may develop their full potential.

    Human cytomegalovirus-induced lesions resembling malignancies have been described in the gastrointestinal tract and include ulcerated or exophytic large masses. The aim of this study was to review the cases registered in the databases of two academic hospitals and formulate a hypothesis concerning the pathogenic mechanisms responsible for cytomegalovirus-induced pseudotumor development. All the diagnoses of human cytomegalovirus infections of the upper gastrointestinal tract recorded from 1991 to 2013 were reviewed. Cases of mucosal alterations misdiagnosed endoscopically as malignancies were selected. Large ulcers occurring in the stomach (three cases) and an irregular exophytic mass at the gastro-jejunal anastomosis were misdiagnosed endoscopically as malignancies (4 cases out of 53). Histologically, all lesions reflected hyperplastic mucosal changes with a prevalence of epithelial and stroma infected cells, without signs of cell atypia. The hypothesis presented is that the development of human cytomegalovirus-induced pseudotumors may be the morphological expression of chronic mucosa damage underlying long-term infection.

    Data on adjuvant chemotherapy in early-stage uterine sarcomas are conflicting and most often based on small patient groups with relatively short duration of follow-up. Approximately 60% of patients present with stage I disease with an overall 5-year survival of 30-50% when treated with surgery alone. This study examines the efficacy and results of long-term follow-up of a multiagent chemotherapy regimen of cyclophosphamide, vincristine, doxorubicin, and dacarbazine (CYVADIC) as adjuvant treatment for patients with stage I uterine sarcoma. Between 1982 and 1999, 24 evaluable patients with completely staged uterine sarcomas received adjuvant multiagent chemotherapy with vincristine sulfate (1mg /m(2)) on days 1 and 4, doxorubicin (40 mg /m(2)) and cyclophosphamide (400 mg /m(2)) on day 2, and dacarbazine (200 mg /m(2)) on days 1 through 4 for a total of nine monthly cycles or until recurrence of disease was documented. Survival distributions were calculated by the Kaplan-Meier method, and statistical significance was determined with the log-rank test. Factors significant on univariate analysis were analyzed in a multivariate fashion using Cox proportional hazards model. The histologic distribution of patients was 46% leiomyosarcoma, 33% mixed mullerian tumors, 13% stromal sarcomas, 4% adenosarcomas, and 4% hemangiosarcoma. The patients received 206 of a planned 216 cycles of chemotherapy. The median follow-up of the patient population was 93 months (range 11-213 months). Eight patients (33%) developed recurrent disease. The median time to recurrence was 19 months (range 7-184 months). The estimated survival for the entire group was 88, 75, and 69% at 2, 5, and 15 years, respectively. Factors that did not affect survival included age, histology, and tumor grade. Four patients required dose reductions secondary to grade 2-3 toxicities (hematologic). Grade 1 neurotoxicity was observed in six patients (25%) and grade 2 neurotoxicity in one patient (4%).

    Objective: To describe the long-term follow-up and distinct phenotype of a large cohort of patients with Gaucher disease type 3 on enzyme replacement therapy (ERT) in Egypt. Methods: A prospective cohort study of 78 patients on ERT who were followed for up to 9 years with yearly evaluations that included EEG and cognitive testing. Results: Of the patients, 73% were homozygous for the L444P GBA1 mutation; all but 7 were neurologically symptomatic. Supranuclear gaze palsy with variable but stable cognitive function was present in 91% of patients. Convergent strabismus and bulbar dysfunction were noted in 22% and 37%, respectively. Features of oppositional defiant disorder were present in 54% of patients. Twenty-three patients (30%) developed seizures while on ERT for 1–9 years. Of those, 12 patients (15%) died suddenly and unexpectedly at a mean age of 6.7 ± 5.0 years (range 1.5–18). Sudden death was usually associated with a seizure disorder or a terminal seizure, but 7 of 12 patients had a preceding normal EEG. An additional 11% had background slowing or epileptogenic activity on EEG without clinical seizures. There were 3 familial cases of sudden unexpected death. Conclusions: Despite having the most common GBA1 genotype known to be associated with neuronopathic Gaucher disease, patients with Gaucher disease type 3 in Egypt have a phenotype and a clinical outcome on ERT that are very different from those observed in other populations. Identifying putative modifying genes of this ethnic group is likely to lead to better therapy for neuronopathic Gaucher disease generally. PMID:27123474

    This study aimed to investigate the long-term effects of group music therapy on agitation manifested by nursing home residents with Alzheimer's disease. A non-randomised experimental design was employed with one group receiving weekly music therapy (n = 26) and another group receiving standard nursing home care (n = 19). Agitation levels were measured five times over one year using the Cohen-Mansfield Agitation Inventory (Cohen-Mansfield, J. (1989). Agitation in the elderly. In N. Billig & P. V. Rabins (Eds.), Issues in geriatric psychiatry (pp. 101-113). Basel, Switzerland: Karger). Although music therapy participants showed short-term reductions in agitation, there were no significant differences between the groups in the range, frequency, and severity of agitated behaviours manifested over time. Multiple measures of treatment efficacy are necessary to better understand the long-term effects music therapy programs have on this population.

    Context: Glucocorticoids and inflammation inhibit bone formation; however, the impact on skeletal modeling is unknown. Objectives: The objectives of the study were to examine changes in bone mineral density (BMD) and cortical structure after Crohn disease (CD) diagnosis and identify associations with growth, glucocorticoids, and disease activity. Design/Participants: This was a prospective cohort study among 76 CD participants, aged 5–21 years. Tibia quantitative computed tomography trabecular BMD and cortical dimensions were obtained at diagnosis and 6 and 12 and a median of 42 months later; 51 completed the final visit. Outcomes: Sex, race, and age-specific Z-scores were generated for outcomes based on more than 650 reference participants, and cortical dimension Z-scores were further adjusted for tibia length. Generalized estimating equations were used to model changes in Z-scores. Results: Disease activity improved over the study interval (P < .001). Trabecular BMD Z-scores improved over the first 6 months; increases were associated with improved disease activity (P < .001), younger age (P = .005), and increases in vitamin D levels (P = .02). Greater increases in tibia length were associated with greater increases in cortical area Z-scores (P < .001). Greater glucocorticoid doses and disease activity were significantly associated with failure to accrue cortical area and were more pronounced with greater linear growth (interaction P < .05). Mean (±SD) trabecular BMD (−1.0 ± 1.21) and cortical area (−0.57 ± 1.10) Z-scores at the final visit were significantly reduced. Conclusions: CD was associated with persistent deficits in trabecular BMD, although younger participants demonstrated a greater potential for recovery. In addition, greater linear growth was associated with a greater recovery of cortical dimensions, especially among participants with less glucocorticoid exposure and inflammation. These data suggest that younger age and concurrent growth

    Abstract Background: Direct-to-implant breast reconstruction can be achieved more easily by means of soft-tissue replacement devices such as dermal matrices and synthetic meshes. The feasibility of a subcutaneous approach has been recently investigated by some studies with different devices functioning as implant support. Aim of this study is to analyze the long-term results, both objective and subjective, of a previous nonrandomized trial comparing prepectoral (subcutaneous) and retropectoral breast reconstructions. Methods: Patients enrolled in a nonrandomized prospective trial, comparing the standard retropectoral reconstruction and the prepectoral subcutaneous approach, using a titanium-coated mesh in both techniques, were followed up and evaluated for long-term results. Cases were compared in terms of the causes and rate of reinterventions, of the postoperative BREAST-Q questionnaire results, and of an objective surgical evaluation. Results: The subcutaneous group had a rate of implant failure and removal of 5.1% when compared with 0% in the retropectoral group. Aesthetic outcome was significantly better for the subcutaneous group both at a subjective and at an objective evaluation. Capsular contracture rate was 0% in the subcutaneous group. Conclusions: A higher rate of implant failure and removal, although not significant, always because of skin flaps and wound problems, should be taken into account for a careful patients selection. The subcutaneous breast reconstruction shows good long-term results. A coherent subjective and objective cosmetic advantage of this approach emerges. Moreover, no capsular contracture is evident, albeit in a relatively limited number of cases. PMID:26893999

    The treatments of avascular osteonecrosis (AVN) include both conservative and surgical methods which are dependent on the stage and progression of the disease. The vasoactive-prostaglandin-analogue iloprost (PGI2) has been utilized in several areas of medicine and recently has been used for the treatment of AVN. A total of 108 patients with 136 osteonecrosis of different joints, etiology and severity were treated with iloprost. The mean follow-up was 49.71 months: range 15-96 months, and outcome measurements recorded regarding subjective complaints, visual analog scale (pain), function and survival. The outcome scores used include the Harris Hip Score, Knee Society score, Foot and Ankle Survey, visual analogue scale (VAS) and a separate questionnaire. The location and etiology of AVN in our study demonstrated the typical pattern. All of the observed side effects of the therapy were minor and completely reversible. Most of patients (74.8%) showed a significant improvement of subjective complaints and decrease in VAS pain scores after the treatment with iloprost. However, 20% of the treated joints with the stadium Association for Research on Osseous Circulation (ARCO) grade 2, 71% with ARCO 3 and 100% with ARCO 4 underwent subsequent total joint replacement. The medical treatment of bone marrow edema or avascular osteonecrosis by Iloprost provides an safe and effective alternative strategy in the management of AVN presenting in the early stages (ARCO 1 or 2). For more advanced stages (ARCO 3 or 4), surgical intervention should be prioritized. PMID:27114807

    Management activities and various land uses have taken place recently that have dramatically altered edaphic and environmental conditions under which forest tree species and ecosystems have evolved. Sequoia giganteum stands, fire suppression in this fire dependent ecosystem has resulted in increased mortality due to Heterobasidion annosum. On hypothesis is that fire suppression results in increased encroachment of true firs, easily infected by S-group Heterobasidion annosum, thereby transferring the disease via root contacts with S. giganteum. Existence of a hybrid with S and P ISG's of H. annosum may be evidence for anthropogenic influences on evolutionary pathways in this pathogen.

    Multiple sclerosis (MS) is a complex, incurable disease. Treatment consists of lifelong disease and symptom management. FDA-approved therapies for relapsing MS include subcutaneous (SC) interferon beta-1b (IFNbeta1b, Betaseron), IM interferon-beta-1a (Avonex), SC interferon-beta-1a (Rebif), glatiramer acetate (Copaxone), and mitoxantrone (Novantrone), all of which are known as disease-modifying agents (DMAs). DMAs that can be initiated and continued on a long-term basis can be referred to as platform therapies. During periods of disease instability with increased disease activity, corticosteroids or immunosuppressive agents can be used in combination with appropriate DMA platform therapy to help control symptoms. To date, long-term comparative studies of DMAs are not available. However, based on the effects of these agents on disability progression, relapse rates, MRI outcomes, and neutralizing antibodies observed in phase III randomized clinical trials, IFNbeta1a products are the DMAs of choice for platform therapy for MS. Evidence indicates that IFNbeta1a may also be beneficial in the early stages of the disease. Research is ongoing to identify other appropriate add-on agents (e.g., antigen-specific therapies) to be used in combination with existing DMAs to effectively manage MS.

    Purpose: To study the initial and long-term results of angioplasty and primary stenting for the treatment of chronic total occlusion (CTO) of the subclavian artery (SA). Materials and Methods: From January 1999 to February 2010, 56 patients (25 men with a mean age of 58 {+-} 8 years) underwent endovascular treatment for CTO of the SA. Duplex scans and arteriograms confirmed occlusion in all cases. Indications for recanalization were subclavian steal syndrome in 33 patients (58.1%), arm claudication in 13 patients (23.2%), and coronary ischemia in 7 patients (12.5%) who had a history of previous coronary artery bypass grafting that included left internal thoracic artery graft. Three patients (5.4%) were treated before the scheduled coronary artery bypass surgery, which included left internal thoracic artery graft. After successful recanalization, all arteries were stented, and all of the patients were followed-up at 1, 3, 6, and 12 months after surgery and annually thereafter. Results: Successful recanalization of the SA was achieved in 46 patients (82.1%), and the complication rate was 7.1%. During follow-up (mean 40 {+-} 26 months; range 2 to 125), the primary patency rates after 1 and 3 years were 97.9% and 82.7%, respectively. At the end of follow-up, 76% of the arteries showed no evidence of restenosis. Univariate analysis failed to identify any variable predictive of long-term patency of successfully recanalized SA. Conclusion: Percutaneous transluminal angioplasty with stenting of the complete total occlusion of the SA is a safe and effective procedure associated with low risks and good long-term results.

    Tenotomie of the sternocleidomastoid muscle seems to be an operation without complications. This impression is confirmed by the majority of reports, most of which however deal with early follow-up results. The basis of this paper is a follow-up of 100 patients, 37 years postoperatively and a review of the literature. There were several avoidable inter- and postoperative complications. Unadequate treatment was one reason for poor results. Good alternative to the cast postoperatively were offered by physiotherapy or the Schanz cotton wool bandage. The use of a cast was followed in a few cases by reversible plexus damage and decubitus ulcers of the head. On the whole the longterm results after torticollis operations were good. Scars and slight recurrence did not disturb the patients seriously. There was no correlation between age at operation and asymmetry of the face.

    Ground surface subsidence was first observed over the Hoe Creek III burn cavity 21 days after gasification ceased. It manifested itself as a small circular depression or sink and was followed five days later by the formation of a second collapse structure. Concurrently, a single large elliptically shaped depression, whose major axis parallels the experimental axis, slowly formed over the burn cavity. These features appear to represent two distinctly different deformation modes. The first mode includes discrete voids that propagate rapidly upward. The second mode is represented by the elliptically shaped classical subsidence depression that forms slowly by a strata bending. Seventeen isolation type survey monuments have been used to track both the horizontal (one dimensional) and vertical motion components intermittently over a 54 month span. The resulting data set is combined with ground surface sketches and post-burn core drilling results and provides an important case study against which numerical and centrifugation model results can be compared. 5 references, 13 figures.

    Objectives The severity of Fabry disease is dependent on the type of mutation in the α-galactosidase A (AgalA) encoding gene (GLA). This study focused on the impact of the GLA haplotype D313Y on long-term organ involvement and function. Setting and participants In this monocentric study, all participants presenting with the D313Y haplotype between 2001 and 2015 were comprehensively clinically investigated at baseline and during a 4-year follow-up if available. Five females and one male were included. Primary and secondary outcome measures Cardiac, nephrological, neurological, laboratory and quality of life data. Results AgalA enzyme activity in leucocytes (0.3±0.9 nmol/min/mg protein (mean±SD)) and serum lyso-Gb3 (0.6±0.3 ng/mL at baseline) were in normal range in all patients. Cardiac morphology and function were normal (left-ventricular (LV) ejection fraction 66±8%; interventricular septum 7.7±1.4 mm; LV posterior wall 7.5±1.4 mm; normalised LV mass in MRI 52±9 g/m2; LV global longitudinal strain −21.6±1.9%) and there were no signs of myocardial fibrosis in cardiac MRI. Cardiospecific biomarkers were also in normal range. Renal function was not impaired (estimated glomerular filtration rate MDRD 103±15 mL/min; serum-creatinine 0.75±0.07 mg/dL; cystatin-c 0.71±0.12 mg/L). One female patient (also carrying a Factor V Leiden mutation) had a transitory ischaemic attack. One patient showed white matter lesions in brain MRI, but none had Fabry-associated pain attacks, pain crises, evoked pain or permanent pain. Health-related quality of life analysis revealed a reduction in individual well-being. At long-term follow-up after 4 years, no significant change was seen in any parameter. Conclusions The results of the current study suggest that the D313Y genotype does not lead to severe organ manifestations as seen in genotypes known to be causal for classical FD. PMID:27059467

    Lignite fueled tangential furnaces, when compared to those burning bituminous coal, have unique design and operating requirements which obligate careful assessment for successful low NOx retrofit. Recently, a Foster Wheeler Energy Corporation Tangential Low NOx (TLN) system was installed at Cooperative Power/United Power Association (CP/UPA) lignite fired Coal Creek Unit No. 2. The system has not only achieved the plant's annual NOx emission compliance requirements, but has also substantially improved furnace operating conditions. After nearly one year of operation, the systems performance has continued to support these results. A second unit is scheduled for retrofit in the Spring of 1999. These results are an important milestone for tangential low NOx technology and serve as a forerunner for future low NOx conversions involving low rank coals.

    Acetabular dysplasia (AD) contributes to the development of osteoarthritis of the hip. A rotational acetabular osteotomy (RAO) is one of the methods of pelvic osteotomy to prevent or treat secondary osteoarthritis of the hip. Although most of the patients that undergo RAO show satisfactory results, some have poor results. This study investigated whether gene polymorphisms of both the vitamin D receptor (VDR) and oestrogen receptor (ER) are involved in both AD and the postoperative results following RAOs. Sixty-four Japanese patients with AD who were treated by an RAO were enrolled in this study (59 women and 5 men, aged 13-59, with an average age of 40.3). Gene polymorphisms of the VDR [ApaI and TaqI restriction fragment length polymorphisms (RFLPs)] and ER (PvuII and XbaI RFLPs) were determined in these patients. The relationship between both the AD and radiographic postoperative changes of the hip joint after an RAO with these gene polymorphisms were examined. The frequencies of ER gene polymorphism coded as pp (RFLP/PvuII) in patients with AD were statistically significantly different (p = .011) from those coded as both PP and Pp. The joint space width narrowed even after RAO in 90% of the patients with the pp gene polymorphism, while it narrowed in only 35% of the patients with either PP or Pp seven years or longer after an RAO. The PvuII polymorphism in the ER gene was associated with the postoperative result of an RAO, while no association was observed between the AD with VDR and ER gene polymorphisms.

    Atrial myopathy, atriotomies, and fibrotic scars are the pathophysiological substrate of lines of conduction block, promoting atrial macroreentry. The aim of this study was to determine the acute and long-term outcome of radiofrequency catheter ablation (RFCA) for right atrial tachyarrhythmia (AT) in adults after cardiac surgery for congenital heart disease (CHD) and acquired heart disease (AHD) and predictors of these outcomes. Clinical records of adults after surgery for heart disease undergoing RFCA of right-sided AT were analyzed retrospectively. Multivariate analyses identified clinical and procedural factors predicting acute and long-term outcomes. A total of 372 patients (69% men; age 61 ± 15 years) after surgical repair of CHD (n = 111) or AHD (n = 261) were studied. Cavotricuspid isthmus-dependent atrial flutter (CTI-AFL) was observed in 300 patients and non-CTI-AFL in 72 patients. Ablation was successful in 349 cases (94%). During a mean follow-up of 51 ± 30 months, recurrences were observed in 24.5% of patients. Multivariate analysis showed that non-CTI-AFL (hazard ratio [HR] 1.78, 95% confidence interval [CI] 1.1 to 2.9) and CHD (HR 1.75, 95% CI 1.07 to 2.9) were independent predictors of long-term recurrences. Multivariate analysis showed that female gender (HR 2.29, 95% CI 1.6 to 3.3), surgery for AHD (HR 95% 2.31, 95% CI 1.5 to 3.7), and left atrial dilatation (HR 2.1, 95% CI 1.3 to 3.2) were independent predictors of long-term atrial fibrillation. In conclusion, RFCA of right-sided AT after cardiac surgery is associated with high acute success rates and significant long-term recurrences. Non-CTI-dependent AFL and surgery for CHD are at higher risk of recurrence. Atrial fibrillation is common during follow-up, particularly in patients with AHD and enlarged left atrium. PMID:25896151

    Type 1 Gaucher disease is an inherited lysosomal enzyme deficiency with variable age of symptom onset. Common presenting signs include thrombocytopenia, anemia, hepatosplenomegaly, bone abnormalities, and, additionally in children, growth failure. Fifty-seven patients aged 3–62 years at the baseline of two phase III trials for velaglucerase alfa treatment were enrolled in the single extension study. In the extension, they received every-other-week velaglucerase alfa intravenous infusions for 1.2–4.8 years at 60 U/kg, although 10 patients experienced dose reduction. No patient experienced a drug-related serious adverse event or withdrew due to an adverse event. One patient died following a convulsion that was reported as unrelated to the study drug. Only one patient tested positive for anti-velaglucerase alfa antibodies. Combining the experience of the initial phase III trials and the extension study, significant improvements were observed in the first 24 months from baseline in hematology variables, organ volumes, plasma biomarkers, and, in adults, the lumbar spine bone mineral density Z-score. Improvements were maintained over longer-term treatment. Velaglucerase alfa had a good long-term safety and tolerability profile, and patients continued to respond clinically, which is consistent with the results of the extension study to the phase I/II trial of velaglucerase alfa.

    Juvenile myelomonocytic leukemia is a clonal malignant disease affecting young children. Current cure rates, even with allogeneic hematopoietic stem cell transplantation, are no better than 50%-60%. Pre-clinical research on juvenile myelomonocytic leukemia is urgently needed for the identification of novel therapies but is hampered by the unavailability of culture systems. Here we report a xenotransplantation model that allows long-term in vivo propagation of primary juvenile myelomonocytic leukemia cells. Persistent engraftment of leukemic cells was achieved by intrahepatic injection of 1×10(6) cells into newborn Rag2(-/-)γc(-/-) mice or intravenous injection of 5×10(6) cells into 5-week old mice. Key characteristics of juvenile myelomonocytic leukemia were reproduced, including cachexia and clonal expansion of myelomonocytic progenitor cells that infiltrated bone marrow, spleen, liver and, notably, lung. Xenografted leukemia cells led to reduced survival of recipient mice. The stem cell character of juvenile myelomonocytic leukemia was confirmed by successful serial transplantation that resulted in leukemia cell propagation for more than one year. Independence of exogenous cytokines, low donor cell number and slowly progressing leukemia are advantages of the model, which will serve as an important tool to research the pathophysiology of juvenile myelomonocytic leukemia and test novel pharmaceutical strategies such as DNA methyltransferase inhibition.

    Objective Smoking is associated with gastroesophageal reflux disease (GERD). Varenicline, a nicotinic receptor partial agonist, is used to aid smoking cessation. The purpose of this study was to prospectively examine the long-term benefits of smoking cessation on GERD and health-related quality of life (HR-QOL). Methods Patients treated with varenicline were asked to fill out a self-report questionnaire about their smoking habits, gastrointestinal symptoms, and HR-QOL before and 1 year after smoking cessation. The prevalence of GERD, frequency of symptoms, and HR-QOL scores were compared. We also investigated associations between clinical factors and newly-developed GERD. Results A total of 141 patients achieved smoking cessation (success group) and 50 did not (failure group) at 1 year after the treatment. The GERD improvement in the success group (43.9%) was significantly higher than that in the failure group (18.2%). The frequency of reflux symptoms significantly decreased only in the success group. There were no significant associations between newly developed GERD and clinical factors including increased body mass index and successful smoking cessation. HR-QOL significantly improved only in the success group. Conclusions Smoking cessation improved both GERD and HR-QOL. Smoking cessation should be recommended for GERD patients. PMID:26845761

    2013-01-01

    Maple syrup urine disease (MSUD) is a rare hereditary metabolic condition where the body is unable to breakdown amino acids causing toxic buildup. Acute and long-term management of MSUD involves a restricted diet and regular monitoring of amino acid levels; however, more recently liver transplants have been shown to be successful in treating this condition. Even with successful management of MSUD there is evidence from pediatric cases that shows a distinct pattern of neurocognitive deficits associated with this condition, including impaired nonverbal skills and psychomotor functioning with relatively intact verbal abilities. In the present paper, we report an adult case of MSUD with associated neurocognitive deficits and functional limitations following liver transplantation. Neuroimaging revealed no structural abnormalities, while the results from the neuropsychological evaluation showed impairment in visual-spatial processing, attention, executive functioning, and psychomotor abilities, with relative strengths in verbal skills. The patient also showed reduced adaptive functioning and mild anxiety. This case demonstrates neurocognitive deficiencies within the context of normal magnetic resonance imaging. The possible underlying mechanism of this neuropsychological profile is discussed in relation to other neurodevelopmental models. PMID:23829516

    Background and purpose — The original Müller acetabular reinforcement ring (ARR) shows favorable medium-term results for acetabular reconstruction in total hip arthroplasty, where it is used when the acetabular bone stock is deficient. However, there are no data regarding long-term survival of the device. We therefore investigated long-term survival and analyzed radiological modes of failure. Patients and methods — Between 1984 and 2002, 321 consecutive primary arthroplasties using an ARR were performed in 291 patients. The mean follow-up time was 11 (0–25) years, and 24 hips were lost to follow-up. For survival analysis, we investigated 321 hips and the end of the follow-up was the date of revision, date of death, or the last patient contact date with implant still in situ. Radiological assessment was performed for 160 hips with a minimum of 10 years of follow-up and with radiographs of sufficient quality. It included evaluation of osteolysis, migration, and loosening. Results — 12 ARR THAs were revised: 1 isolated ARR revision for aseptic loosening, 4 revisions of the ARR and the stem for aseptic loosening, 6 for infection, and 1 for recurrent dislocation. The cumulative revision rate for all components, for any reason, at 20 years was 15% (95% CI: 10–22), while for the ARR only it was 7% (95% CI: 4–12) for any reason and 3.4% (95% CI: 1–9) for aseptic loosening. 21 (13%) of 160 ARR THAs examined had radiological changes: 7 had osteolysis but were not loose, and 14 were radiologically loose but were not painful and not revised. Interpretation — Our data suggest that the long-term survival of the ARR is excellent. PMID:26471881

    Many studies have investigated how social insects behave when a parasite is introduced into their colonies. These studies have been conducted in the laboratory, and we still have a limited understanding of the dynamics of ant-parasite interactions under natural conditions. Here we consider a specialized parasite of ant societies (Ophiocordyceps camponoti-rufipedis infecting Camponotus rufipes) within a rainforest. We first established that the parasite is unable to develop to transmission stage when introduced within the host nest. Secondly, we surveyed all colonies in the studied area and recorded 100% prevalence at the colony level (all colonies were infected). Finally, we conducted a long-term detailed census of parasite pressure, by mapping the position of infected dead ants and foraging trails (future hosts) in the immediate vicinity of the colonies over 20 months. We report new dead infected ants for all the months we conducted the census – at an average of 14.5 cadavers/month/colony. Based on the low infection rate, the absence of colony collapse or complete recovery of the colonies, we suggest that this parasite represents a chronic infection in the ant societies. We also proposed a “terminal host model of transmission” that links the age-related polyethism to the persistence of a parasitic infection. PMID:25133749

    Repeated bleeding in the joint cavities is the most annoying symptom and often has disabling effects in patients with hemophilia (PWH). Our aim was to study the effect of radiosynovectomy (RSO) with beta particle-emitting radiocolloids in the treatment of hemorhagic arthropathy. We have treated 22 joints from 18 patients with hemophilia A, from April 2008 to February 2012, 5 knees, 11 elbows and 6 ankles. Joints were divided into two Groups, those treated with yttrium-90-citrate ((90)Y-C) (5 knees, 2 of them twice)-Group I and those with rhenium-186-sulfide ((186)Re-S) (11 elbows, 1 of them treated twice and 6 ankles)-Group II. A total of 25 treatments. Follow-up period was 3 months, 1 year and 3 years. Results showed a favourable subjective and a better objective result in all 5 joints of Group I and in 15/17 joints of Group II, respectively. Follow-up after 3 months showed significant improvement in Hemophilia Join Health Score (HJHS) after 20 treatments and steady score after 5 treatments. After 1 year, 19 treated joints had improved for the first time, 3 remained steady and 3 were not examined. After 3 years, 9 treated joints were HJHS steady, while 16 were not examined. One year after treatment, 13/14 joints of patients, aged 6-23 years showed better HJHS score, while 9/11 joints of patients aged 26-51 years, showed better HJHS. Synovial membrane thickness as measured by MRI in 8 joints, before and 3 months after treatment was not related to prognosis. In conclusion, in a small group of hemophilic patients with hemorrhagic arthropathy treated with (90)Y-C and with (186)Re-S, our study showed good results irrespective of age in 22/25 treatments after 3 months or 1 year. The thickness of synovial membrane in the 8 joints studied was not related to prognosis.

    Fourty patients with 32 hydroceles and 11 epididymal cysts were treated by aspiration and instillation of tetracycline. After a follow up period of 24-39 months the cure rate was 77%. Most of the early recurrences were the results of chemical inflammation and vanished spontaneously. This group should therefore not be operated on until three months after their initial treatment. As aspiration of the fluid had allowed palpation of the testis and cytological examination, only a small proportion of patients with recurrences wanted further treatment. We therefore recommend tetracycline sclerotherapy because it is quick, easy, safe, and effective in the long as well as the short term.

    The present work characterizes the time-space scales of variability and forcing dependencies of a unique 26 year record of daily to hourly shoreline data from a steep beach at Duck, North Carolina. Shoreline positions over a 1500 m alongshore span were estimated using a new algorithm called ASLIM based on fitting the band of high light intensity in time exposure images to a local Gaussian fit, with a subsequent Kalman filter to reduce noise and uncertainty. Our findings revealed that the shoreline change at long times scales dominates seasonal variability, despite that wave forcing had only 2% variance at interannual frequencies. The shoreline response presented 66% of the variance at interannual scales. These results were not expected since from wave forcing it would have been expected that the shoreline response should similarly lack interannual variability, but we found it to be dominated by this scale. The alongshore-mean shoreline time series revealed no significant annual cycle. However, there are annual oscillations in the shoreline response that are coherent with wave forcing and deserves further explanations. The pier was found to have a significant influence on shoreline behavior since restricts the seasonal longshore transport between the sides, resulting in a seasonally reversing sediment accumulation. Thus, there is a significant annual peak in shoreline variability that is coherent with the annual forcing but becomes insignificant in the longshore-average.

    Dissolved organic carbon (DOC) fluxes are recently increasing in surface waters of humid climate regions. Due to its substantial importance for leaching processes, aquatic foodwebs, and drinking water purification a better understanding of sources and pathways of DOC is needed. Therefore this study aims to analyse and simulate DOC fluxes in agricultural ecosystems with selected crop rotations. A data set of 24 lysimeters of the UFZ Lysimeter station at Falkenberg (Saxony-Anhalt) covering nine years of DOC investigation has been selected and examined. The data set covers a wide range of climatic conditions with deviating management practices for grasslands and agricultural crop rotations. The monthly DOC concentrations assessed in the leached water range from 2.4 to 34.1 mg /l. DOC concentrations depend on temperature, precipitation and discharge. The type of crop grown on the lysimeter is an important trigger for DOC leaching - especially lysimeters used as pasture, or planted with rape and carrots exhibit high DOC concentrations. Management practices and fertilizer application modify the leaching of DOC and offer potentials to reduce DOC losses. The results form the basis of further process simulation studies and upscaling of the results to the small catchment scale.

    Background Differences in biological changes from weight loss by energy restriction and/or exercise may be associated with differences in long-term weight loss/regain. Objective To assess the effect of weight loss method on long-term changes in weight, body composition and chronic disease risk factors. Data Sources PubMed and Embase were searched (January 1990-October 2013) for studies with data on the effect of energy restriction, exercise (aerobic and resistance) on long-term weight loss. Twenty articles were included in this review. Study Eligibility Criteria Primary source, peer reviewed randomized trials published in English with an active weight loss period of >6 months, or active weight loss with a follow-up period of any duration, conducted in overweight or obese adults were included. Study Appraisal and Synthesis Methods Considerable heterogeneity across trials existed for important study parameters, therefore a meta-analysis was considered inappropriate. Results were synthesized and grouped by comparisons (e.g. diet vs. aerobic exercise, diet vs. diet + aerobic exercise etc.) and study design (long-term or weight loss/follow-up). Results Forty percent of trials reported significantly greater long-term weight loss with diet compared with aerobic exercise, while results for differences in weight regain were inconclusive. Diet+aerobic exercise resulted in significantly greater weight loss than diet alone in 50% of trials. However, weight regain (∼55% of loss) was similar in diet and diet+aerobic exercise groups. Fat-free mass tended to be preserved when interventions included exercise. PMID:25333384

    16 cases were selected randomly from a group of 36 postoperative patients who underwent velopharyngeal ring ligation 16 years ago for evaluation of pronunciation, pharyngeal radiography, and electric endostroboskop to evaluate the patients' velopharygeal closure function. It was found that the pronunciation function of 93% patients were in good status. The results showed that centripetal force of velopharyngeal ring ligation made the velopharyngeal cavity reduced from the right to left and from anterior to posterior sides. It was good for sphincter of velopharyngeal moving, which could reduce the space of pharyngeal cavity and add the length of soft palate. The velopharyngeal closure was improved, which produced a good condition for the recovery of pronunciation function, at the same time, the change of pharyngeal cavity adapts to the patient's growth without limiting the growth and development of nasovelopharyngeal.

    Eight patients with primary lymphoedema secondary to iliac lymph node and vessel obstruction were treated in 1977 and 1978 by the construction of an enteromesenteric bridge. All patients have been followed clinically for periods of 2.5-7 years. Six patients showed sustained clinical improvement. Two failed to improve and subsequently required leg reducing operations. Contrast lymphography was performed in the early postoperative period on all cases and showed function of the bridge in five. Isotope lymphography 6-7 years postoperatively showed normal clearance of isotope from three of the four limbs studied. In one patient contrast lymphography, performed 7 years postoperatively, confirmed continued conduction of lymph by the enteromesenteric bridge. These results have encouraged us to reintroduce this operation for suitable patients.

    Previously at SAMAP we reported on the development of tunable diode laser spectroscopy (TDLS) based instruments for measuring small gas molecules in real time. TDLS technology has matured rapidly over the last 5 years as a result of advances in low power diode lasers as well as better detection schemes. In collaboration with two small businesses Vista Photonics, Inc. and Nanoracks LLC, NASA developed a 4 gas TDLS based monitor for an experimental demonstration of the technology on the International Space Station (ISS). Vista invented and constructed the core TDLS sensor. Nanoracks designed and built the enclosure, and certified the integrated monitor as a payload. The device, which measures oxygen, carbon dioxide, ammonia and water vapor, is called the Multi-Gas Monitor (MGM). MGM measures the 4 gases every few seconds and records a 30 second moving average of the concentrations. The relatively small unit draws only 2.5W. MGM was calibrated at NASA-Johnson Space Center in July 2013 and launched to ISS on a Soyuz vehicle in November 2013. Installation and activation of MGM occurred in February 2014, and the unit has been operating nearly continuously ever since in the Japanese Experiment Module. Data is downlinked from ISS about once per week. Oxygen and carbon dioxide data is compared with that from the central Major Constituents Analyzer. Water vapor data is compared with dew point measurements made by sensors in the Columbus module. The ammonia channel was tested by the crew using a commercial ammonia inhalant. MGM is remarkably stable to date. Results of 18 months of operation are presented and future applications including combustion product monitoring are discussed.

  12. Long-term aging of cast stainless steels: Mechanisms and resulting properties

    Mechanical property data are presented from Charpy-impact, tensile, and J-R curve tests for several heats of cast stainless steel aged up to 10,000 h at 450, 400, 350, 320, and 290/sup 0/C. The results indicate that thermal aging increases the tensile strength and decreases the impactenergy, J/sub IC/ and tearing modulus of the steels. Also, the ductile-to-brittle transition curve shifts to higher temperatures. The low-carbon CF-3 steels were the most resistant and the molybdenum-containing high-carbon CF-8M steels were the most susceptible to low-temperature embrittlement. The influence of nitrogen content and distribution of ferrite on loss of toughness are discussed. Data also indicate that existing correlations do not accurately represent the embrittlement behavior over the temperature range 280 to 450/sup 0/C, i.e., extrapolation of high-temperature data to reactor temperatures may not be valid for some compositions of cast stainless steels. 13 refs., 13 figs., 2 tabs.

    Between July 1989 and December 2002, 172 women with Stage I/II breast cancer were treated by breast conservation therapy (BCT). All underwent quadrantectomy and axillary node clearance. Minimum follow-up was 5 years and 79 (52%) were followed for >10 years. At 5 years, local relapse-free and overall survival rates were 98.3% and 98.3%. The 10-year rates were 95% and 94%, respectively. The 10-year local recurrence rate was higher in patients with involved margins (33.3% versus 2.7%, p = 0.0272). Furthermore 10-year death rates in margin positive patients were higher (18.2% versus 2.5%, p = 0.0486). Excellent or good cosmetic results were achieved in 54%. BCT is a reasonable option for early stage breast cancer in Chinese women but margin status is the most important determinant of local recurrence. Negative margins are required for optimal local control and minimization of distant metastasis.

    V sge is a spectroscopic binary with an orbital period of 0.514195d. The system's overall brightness was reported to vary erratically from 9 to 13 mag on time scale of months. The system displays a superimposed orbital light curve with both primary and secondary minima. Herbig et al. presented in 1965 a description of the system as a semi-detached one with the less massive component filling its Roche lobe, and the companion embedded oin a disk fed by gas passing through the vicinity of Li. More gas should be lost from the system by an unspecified mechanism. There have been many attempts to explain the model of V Sge in various alternative ways. Nevertheless, new papers and contributions are getting back to the original model given by Herbig et al. The observational material was obtained in the frame of the international photoelectric campaign. We have collected data from Skalnate Pleso, Hlohovec, Kryonerion, Brno and Crimea Observatories and reanalyzed the data provided by Mader and Shafter. Our first observations started in October 30, 1995 and have been continued to the present. We are presenting very preliminary results of the flickering study of this nova-like cataclysmic variable.

    The military have a considerable amount of experience from using robots for mine clearing and bomb removal. As new technology emerges it is necessary to investigate the possibly to expand robot use. This study has investigated an Army company, specialized in urban operations, while fulfilling their tasks with the support of a PackBot Scout. The robot was integrated and deployed as an ordinary component of the company and included modifying and retraining a number of standard behaviors to include the robot. This paper reports on the following issues: evaluation of missions where the platform can be deployed, what technical improvements are the most desired, and what are the new risks introduced by use of robots? Information was gathered through observation, interviews, and a questionnaire. The results indicate the robot to be useful for reconnaissance and mapping. The users also anticipated that the robot could be used to decrease the risks of IEDs by either triggering or by neutralising them with a disruptor. The robot was further considered to be useful for direct combat if armed, and for placing explosive loads against, for example, a door. Autonomous rendering of maps, acquiring images, two-way audio, and improved sensing such as IR were considered important improvements. The robot slowing down the pace of the unit was considered to be the main risk when used in urban operations.

    Aneurysms of extracranial arteries are sufficiently rare pathology in the extracranial arteries surgery. The authors aimed to research the frequency of occurrence of the extracranial arteries aneurysm, reasons of the onset, the localization, clinical manifestations and surgical treatment strategy. A retrospective study presents 10 cases of the extracranial arteries aneurysm for the last 5 years. A presence of aneurysmatic dilatation of extra-cranial arteries was detected according to the data of ultrasonic duplex scanning (UDS) and patients were directed to the hospital. The UDS was carried out as a routine procedure because of the presence of earlier acute stroke or the transitory ischemic attack. All the patients were carefully examined. A computed tomography and the recurring UDS were performed and the neurologic status of patients was estimated. An indication to surgical treatment was an increase of the internal carotid artery diameter and the common carotid artery more than 50% or equal to it. The presence of the local saccular aneurysm was one of the reasons. Surgical treatment strategy was determined by the anatomic position and possibilities for the reconstruction. The results of given operations showed, that the surgical treatment strategy should be recommended and could be fully justified in this pathology.

    Concentrations of trace elements in wheat grain sampled between 1967 and 2003 from the Swedish long-term soil fertility experiments were analyzed using ICP-MS. The long-term effect of inorganic and organic fertilization on trace metal concentrations was investigated including the impact of atmospheric deposition and myccorhiza, whereas other factors such as soil conditions, crop cultivar, etc. are not discussed in this paper. Mean values derived from 10 experimental sites were reported. Significantly declining Pb and Cd concentrations in wheat grain could be explained by lower atmospheric deposition. Mean Se contents in all samples were 0.031 mg kg(-1) grain dry weight. No samples had sufficiently high Se concentrations for human (0.05 mg Se kg(-1)) or animal demand (0.1 mg Se kg(-1)). Concentrations of Co in wheat grain were extremely low, 0.002-0.005 mg Co kg(-1) grain dry weight, and far below the minimum levels required by animals, which applied to all fertilizer treatments. A doubling of Mo concentrations in grain since 1975 resulted in Cu/Mo ratios often below one, which may cause molybdenosis in ruminants. The increase in Mo concentrations in crops correlated with the decline in sulfur deposition. Concentrations of Cu and Fe declined in NPK-fertilized wheat as compared to unfertilized or manure-treated wheat. Very low concentrations of Se and Co and low concentrations of Fe and Cu require attention to counteract risks for deficiencies. The main characteristic of the study is that there are few significant changes over time between different fertilizer treatments, but throughout there are low concentrations of most trace elements in all treatments. In general, good agreement between concentrations in wheat from the long-term fertility experiments and the national monitoring program indicate that values are representative. PMID:19263225

    Despite promising results with targeted drugs, chemoimmunotherapy with fludarabine, cyclophosphamide (FC), and rituximab (R) remains the standard therapy for fit patients with untreated chronic lymphocytic leukemia (CLL). Herein, we present the long-term follow-up of the randomized CLL8 trial reporting safety and efficacy of FC and FCR treatment of 817 treatment-naïve patients with CLL. The primary end point was progression-free survival (PFS). With a median follow-up of 5.9 years, median PFS were 56.8 and 32.9 months for the FCR and FC group (hazard ratio [HR], 0.59; 95% confidence interval [CI], 0.50-0.69, P < .001). Median overall survival (OS) was not reached for the FCR group and was 86.0 months for the FC group (HR, 0.68; 95% CI, 0.54-0.89, P = .001). In patients with mutated IGHV (IGHV MUT), FCR improved PFS and OS compared with FC (PFS: HR, 0.47; 95% CI, 0.33-0.68, P < .001; OS: HR, 0.62; 95% CI, 0.34-1.11, P = .1). This improvement remained applicable for all cytogenetic subgroups other than del(17p). Long-term safety analyses showed that FCR had a higher rate of prolonged neutropenia during the first year after treatment (16.6% vs 8.8%; P = .007). Secondary malignancies including Richter's transformation occurred in 13.1% in the FCR group and in 17.4% in the FC group (P = .1). First-line chemoimmunotherapy with FCR induces long-term remissions and highly relevant improvement in OS in specific genetic subgroups of fit patients with CLL, in particular those with IGHV MUT. This trial was registered at www.clinicaltrials.gov as #NCT00281918. PMID:26486789

    Investigations on the impact of application of biosolids for land reclamation on C sequestration in soil were conducted at Fulton County, Illinois, where 41 fields (3.6-66 ha) received biosolids at a cumulative loading rate from 455 to 1654 dry Mg ha(-1) for 8 to 23 yr in rotation from 1972 to 2004. The fields were cropped with corn, wheat, and sorghum and also with soybean and grass or fallowed. Soil organic carbon (SOC) increased rapidly with the application of biosolids, whereas it fluctuated slightly in fertilizer controls. The peak SOC in the 0- to 15-cm depth of biosolids-amended fields ranged from 4 to 7% and was greater at higher rates of biosolids. In fields where biosolids application ceased for 22 yr, SOC was still much higher than the initial levels. Over the 34-yr reclamation, the mean net soil C sequestration was 1.73 (0.54-3.05) Mg C ha(-1) yr(-1) in biosolids-amended fields as compared with -0.07 to 0.17 Mg C ha(-1) yr(-1) in fertilizer controls, demonstrating a high potential of soil C sequestration by the land application of biosolids. Soil C sequestration was significantly correlated with the biosolids application rate, and the equation can be expressed as y = 0.064x - 0.11, in which y is the annual net soil C sequestration (Mg C ha(-1) yr(-1)), and x is annual biosolids application in dry weight (Mg ha(-1) yr(-1)). Our results indicate that biosolids applications can turn Midwest Corn Belt soils from current C-neutral to C-sink. A method for calculating SOC stock under conditions in which surface soil layer depth and mass changes is also described.

    Surface reflectance is one of the key products from VIIRS and as with MODIS, is used in developing several higher-order land products. The VIIRS Surface Reflectance (SR) IP is based on the heritage MODIS Collection 5 product (Vermote et al. 2002). The quality and character of surface reflectance depends on the accuracy of the VIIRS Cloud Mask (VCM) and aerosol algorithms and of course on the adequate calibration of the sensor. Early evaluation of the VIIRS SR product in the context of the maturity of the operational processing system known as the Interface Data Processing System (IDPS), has been a major focus of work to-date, but is now evolving into the development of a VIIRS suite of Climate Data Records produced by the NASA Land Science Investigator Processing System (SIPS). We will present the calibration performance and the role of the surface reflectance in calibration monitoring, the performance of the cloud mask with a focus on vegetation monitoring (no snow conditions), the performance of the aerosol input used in the atmospheric correction with quantitative results of the performance of the SR product over AERONET sites. Based on those elements and further assessment, we will address the readiness of the SR product for the production of higher-order land products such as Vegetation Indices, Albedo and LAI/FPAR, the its application to agricultural monitoring and in particular the integration of VIIRS data into the global agricultural monitoring (GLAM) system developed at UMd. Finally from the lessons learned, we will articulate a set of critical recommendations to ensure consistency and continuity of the JPSS mission with the MODIS data record.

    Background N-stage is related to distant metastasis in nasopharyngeal carcinoma (NPC) patients. The purpose of this study was to evaluate the efficacy and toxicity of different nedaplatin-based chemotherapy regimens in advanced N2-3 stage NPC patients treated with intensity modulated radiation therapy (IMRT). Patients and Methods Between April 2005 and December 2009, a total of 128 patients with N2-3 advanced NPC were retrospectively analyzed. Patients were treated with IMRT concurrent with 2 cycles of chemotherapy consisting of either nedaplatin plus paclitaxel (NP group, n = 67) or nedaplatin plus fluorouracil and paclitaxel (NFP group, n = 61). Two to four cycles of adjuvant chemotherapy were then administered every 21 days following concurrent chemoradiotherapy. Results With a median follow-up of 60 months, the 5-year overall survival (OS), progression-free survival (PFS), local-regional recurrence-free survival (LRRFS), and distant metastasis-free survival (DMFS) for all patients were 81.4%, 71.5%, 87.8% and 82.0%, respectively. No significant difference in PFS (66.6% vs. 76.7%, P = 0.212) and LRRFS rates (89.0% vs. 86.3%, P = 0.664) was observed between the NP and NFP groups. The 5-year OS (75.4% vs. 88.5%, P = 0.046) and DMFS (75.1% vs. 89.0%, P = 0.042) rate were superior in the NFP group compared with the NP group. The NFP group had a higher incidence of grade 3–4 acute toxicities including bone marrow suppression (leukopenia: χ2 = 3.935, P = 0.047; anemia: χ2 = 9.760, P = 0.002; thrombocytopenia: χ2 = 8.821, P = 0.003), and both liver and renal dysfunction (χ2 = 5.206, P = 0.023) compared with the NP group. Late toxicities were moderate and no difference was observed between the two groups. Conclusion IMRT concurrent with nedaplatin-based chemotherapy is an advocated regimen for patients with advanced N2-3 stage NPC. Patients with advanced N2-3 stage may be better candidates for the NFP regimen although this regimen was associated with a high acute

    Up-to-date space geodesy investigations take full advantage of various techniques data joint processing. The poster presents solutions (time series of North, East, Up components) of selected stations, which adopted Satellite Laser Ranging (SLR) and Global Positioning System (GPS) techniques and which were gathering the data in the same time (from 1994 to 2011). Processing of both types of data was made according to Global Geodetic Observing System (GGOS) recommendations. The main goal was to obtain coordinates and their changes in time (velocities) basing on both techniques data gathered between 1994 and 2011 and to compare the results (until now, preliminary analysis for the period 1996-2001.5 were made). The station coordinates were determined for the for first day of each month (SLR technique) and for the middle of each week (GPS technique) . Monthly orbital arcs for laser observations were created basing on solutions from several SLR sites (observations to LAGEOS-1 and LAGEOS-2 satellites) with the best solutions quality and the highest amount of observations. For GNSS coordinates determination about 130 sites belonging to International GNSS Service (IGS) were selected: 30 with local ties to SLR sites and others basing on their geolocalization (length of the baselines) and solutions time series analysis. Mainly, core IGS stations with long observation history were used. Due to small number of GPS sites in the period 1996-2000 and long baselines between them, the network was divided into seven subnetworks which were processed separately. The station coordinates were expressed in ITRF2008 for the epoch of 2005 and compared to the catalogue values. The GPS solutions were reduced to the SLR markers positions using local ties. Velocities from GPS and SLR processing were determined by the means of linear regression and compared to the ITRF2008 and the NNR NUVEL 1A model. Solutions of both techniques were analyzed in order to verify agreement of both techniques and

    Purpose Anaplastic oligodendrogliomas, pure (AO) and mixed (anaplastic oligoastrocytoma [AOA]), are chemosensitive, especially if codeleted for 1p/19q, but whether patients live longer after chemoradiotherapy is unknown. Patients and Methods Eligible patients with AO/AOA were randomly assigned to procarbazine, lomustine, and vincristine (PCV) plus radiotherapy (RT) versus RT alone. The primary end point was overall survival (OS). Results Two hundred ninety-one eligible patients were randomly assigned: 148 to PCV plus RT and 143 to RT. For the entire cohort, there was no difference in median survival by treatment (4.6 years for PCV plus RT v 4.7 years for RT; hazard ratio [HR] = 0.79; 95% CI, 0.60 to 1.04; P = .1). Patients with codeleted tumors lived longer than those with noncodeleted tumors (PCV plus RT: 14.7 v 2.6 years, HR = 0.36, 95% CI, 0.23 to 0.57, P < .001; RT: 7.3 v 2.7 years, HR = 0.40, 95% CI, 0.27 to 0.60, P < .001), and the median survival of those with codeleted tumors treated with PCV plus RT was twice that of patients receiving RT (14.7 v 7.3 years; HR = 0.59; 95% CI, 0.37 to 0.95; P = .03). For those with noncodeleted tumors, there was no difference in median survival by treatment arm (2.6 v 2.7 years; HR = 0.85; 95% CI, 0.58 to 1.23; P = .39). In Cox models that included codeletion status, the adjusted OS for all patients was prolonged by PCV plus RT (HR = 0.67; 95% CI, 0.50 to 0.91; P = .01). Conclusion For the subset of patients with 1p/19q codeleted AO/AOA, PCV plus RT may be an especially effective treatment, although this observation was derived from an unplanned analysis.

    Context: Functional growth hormone producing adenomas have long-term deleterious effects on the visual apparatus, the cardiovascular and musculoskeletal systems, and often predispose to malignancies. Since persistence of acromegaly affects outcome and quality of life, therapeutic interventions become mandatory. Aim: This study represents an analysis of long-term clinical and endocrinal outcome of 115 patients of acromegaly after surgical management. Setting and Design: Tertiary care retrospective study. Materials and Methods: One hundred and fifteen patients (male:female ratio: 1:1.09) with acromegalic features were studied. Apart from acromegalic features, their main clinical presentation also included headache, diminution of vision, field defects, ptosis, irregular menstruation, diabetes insipidus, diabetes mellitus and hypertension. Six of them presented with apoplexy. Their preoperative endocrinal evaluation included basal and suppressed growth hormone (GH), prolactin and thyroid levels. On the basis of axial and coronal CT scan or multiplanar MR imaging or both, the tumors were classified according to their suprasellar and parasellar extension (Hardy's grade). Transnasal trans-sphenoidal surgery (TSS) (n = 37) and sublabial, rhinoseptal TSS (n = 72) were the preferred approaches. Six patients with significant parasellar extensions underwent trans-cranial explorations. The patients were followed up at 6 and 12 weeks and then at 6 monthly intervals. Hormonal and CT/MR evaluation were also done. Attainment of random GH value less than 2.5 µg/L, and the nadir GH value after oral glucose tolerance test (OGTT) less than 1 µg/L were used as the criteria of cure. Findings: The patients were preoperatively in Hardy's tumor grade 0 (29), A (21), A+E (3), B (21), B+E (5), C (9), C+E (10), D (1) D+E (11), E (5), respectively. One hundred and one patients were available for follow-up (FU; median FU duration: 84 months; range: 6 to 132 months). Surgical cure was achieved

    The pathogenesis of allergies can be stimulated by adjuvant effects--i.e. air pollutants such as NO(2) and particles from diesel exhausts as well as noise--the latter especially during night-time. During sleep, noise signals which are associated with danger (i.e. lorry noise) have the potential to trigger stress reactions even if the noise level is low. Increases of cortisol in the first half of the night seem to play an important role. In a blind interview study, the combined effects of chronic exposure to traffic related air pollution and noise, upon the risk of skin and respiratory diseases in children were studied. All children between 5-12 years, who had consulted one of two participating paediatricians were included in the study. The paediatricians diagnoses of 400 children were analysed together with their parents answers regarding the density of road traffic on their street and several confounding factors. Multiple regression analyses resulted in relative risks of asthma, chronic bronchitis and neurodermitis, which increased significantly with increasing traffic load. A comparison with the literature on such effects caused by air pollution alone, showed that traffic noise during the night might have an adjuvant effect on the pathogenesis of the mentioned diseases.

    The objective of this paper is to evaluate the long-term functional results achieved after open reduction and internal fixation of 24 distal humerus non-unions. Non-unions were extra-articular-extracapsular (11 cases), extra-articular-intracapsular (8 cases) and intra-articular (5 cases). Preoperative elbow range of motion averaged 45 degrees. Time between original trauma and revision surgery averaged 14 months. Stabilisation methods varied according to type and location of the non-union. Follow-up averaged 46 months (range: 18-108). Elbow range of motion at last examination averaged 98 degrees . Flexion averaged 110 degrees and extension loss averaged 17 degrees . The disabilities of the arm, shoulder and hand (DASH) score averaged 16 points. Secondary transposition of the ulnar nerve was necessary in three cases. Sixteen patients reported no pain at last examination, seven had mild pain and one had moderate pain. Distal humerus non-unions present different characteristics; consequently, surgical treatment must be individualised for each patient. Even though they are demanding procedures, bony union and good long-term functional results were achieved.

    ABSTRACT Objectives We analyzed the long-term oncologic outcome for patients with prostate cancer and transurethral resection who were treated using low-dose-rate (LDR) prostate brachytherapy. Methods and Materials From January 2001 to December 2005, 57 consecutive patients were treated with clinically localized prostate cancer. No patients received external beam radiation. All of them underwent LDR prostate brachytherapy. Biochemical failure was defined according to the “Phoenix consensus”. Patients were stratified as low and intermediate risk based on The Memorial Sloan Kettering group definition. Results The median follow-up time for these 57 patients was 104 months. The overall survival according to Kaplan-Meier estimates was 88% (±6%) at 5 years and 77% (±6%) at 12 years. The 5 and 10 years for failure in tumour-free survival (TFS) was 96% and respectively (±2%), whereas for biochemical control was 94% and respectively (±3%) at 5 and 10 years, 98% (±1%) of patients being free of local recurrence. A patient reported incontinence after treatment (1.7%). The chronic genitourinary complains grade I were 7% and grade II, 10%. At six months 94% of patients reported no change in bowel function. Conclusions The excellent long-term results and low morbidity presented, as well as the many advantages of prostate brachytherapy over other treatments, demonstrates that brachytherapy is an effective treatment for patients with transurethral resection and clinical organ-confined prostate cancer.

    The survivorship of total hip arthroplasty in younger patients is dependent on the wear characteristics of the bearing surfaces. Long-term results with conventional polyethylene in young patients show a high failure rate. This study assessed the long-term results of a first-generation annealed highly cross-linked polyethylene (HCLPE) in uncemented total hip arthroplasty in young, active patients. Between 1999 and 2003, 112 total hip arthroplasty procedures performed in 91 patients with an average University of California Los Angeles activity score of 8 and mean age of 53 years (range, 24-65 years) were included from a prospective database. In all patients, a 28-mm metal femoral head on annealed HCLPE (Crossfire; Stryker, Mahwah, New Jersey) was used. At minimum 10-year follow-up (11.5±0.94 years), Kaplan-Meier survivorship was 97% for all failures (1 periprosthetic infection and 1 late dislocation) and 100% for mechanical failure (no revisions for osteolysis or loosening). This study showed low revision rates for wear-related failure and superior survivorship in young, active patients. Oxidation causing failure of the locking mechanism has not been a problem with Crossfire for up to 10 years. PMID:26811959

    Purpose. To compare the long-term clinical outcomes of cultivated limbal epithelial transplantation (CLET) in children and adults with limbal stem cell deficiency. Design. Retrospective case series. Methods. Case records of patients with limbal stem cell deficiency (LSCD) who underwent CLET from April 2004 to December 2014 were studied. Outcome measures were compared in terms of anatomical success and visual improvement. Parameters for total anatomical success were avascular, epithelized, and clinically stable corneal surface without conjunctivalization, whereas partial anatomical success was considered when mild vascularization (sparing centre of cornea) and mild conjunctivalization were noted along with complete epithelization. Results. A total of 62 cases underwent the CLET procedure: 38 (61.3%) were children and 24 (38.7%) were adults. Patients with unilateral LSCD (33 children and 21 adults) had autografts and those with bilateral LSCD (5 children and 3 adults) had allografts. Amongst the 54 autografts partial and total anatomical success were noted in 21.2% and 66.6% children, respectively, and 19.0% and 80.9% in adults, respectively (p value 0.23). Visual improvement of 1 line and ≥2 lines was seen in 57.5% and 21.2% children, respectively, and 38% and 38% in adults, respectively (p value 0.31). Conclusion. Cultivated limbal epithelial transplantation gives good long-term results in patients with LSCD and the outcomes are comparable in children and adults. PMID:26770973

    Based on the preclinical data and the results of a phase II futility study, creatine was selected for an efficacy trial in Parkinson's disease (PD). We present the design rationale and a description of the study cohort at baseline. A randomized, multicenter, double-blind, parallel-group, placebo-controlled phase III study of creatine (10 g daily) in participants with early, treated PD, the Long-term Study-1 (LS-1), is being conducted by the National Institute of Neurological Disorders and Stroke Exploratory Trials in Parkinson's Disease network. The study utilizes a global statistical test (GST) encompassing five clinical rating scales to provide a multidimensional assessment of disease progression. A total of 1,741 PD participants from 45 sites in the United States and Canada were randomized 1:1 to either 10 g of creatine/day or matching placebo. Participants are being evaluated for a minimum of 5 years. The LS-1 baseline cohort includes participants treated with dopaminergic therapy and generally mild PD. LS-1 represents the largest cohort of patients with early treated PD ever enrolled in a clinical trial. The GST approach should provide high power to test the hypothesis that daily administration of creatine (10 g/day) is more effective than placebo in slowing clinical decline in PD between baseline and the 5-year follow-up visit against the background of dopaminergic therapy and best PD care.

    Background and Purpose The blood brain-barrier (BBB) is disrupted in small vessel disease (SVD) patients with lacunes and white matter hyperintensities (WMHs). The relationship of WMHs and regional BBB permeability changes has not been studied. We hypothesized that BBB disruption occurs in normal appearing WM (NAWM) and regions near the WMHs. To test the hypothesis, we repeated BBB permeability measurements in patients with extensive WMHs related to Binswanger’s disease (BD). Methods We selected a subset of 22 BD subjects from a well-characterized larger prospective vascular cognitive impairment cohort. We used 16 age-matched controls for comparison. The abnormal WM permeability (WMP) was measured twice over several years using dynamic contrast-enhanced MRI (DCEMRI). WMP maps were constructed from voxels above a predetermined threshold. Scans from first and second visits were co-registered. WM was divided into 3 regions: NAWM, WMH ring and WMH core. The ring was defined as 2mm on each side of the WMH border. WMP was calculated in each of the three specific regions. We used paired t-test, ANOVA and Fisher’s exact test to compare individual changes. Results WMP was significantly higher in subjects than controls (p<0.001). There was no correlation between WMH load and WMP. High permeability regions had minimal overlap between first and second scans. Nine percent of WMP was within the WMHs, 49% within the NAWM, and 52% within the WMH ring (p<0.001; ANOVA). Conclusions Increased BBB permeability in NAWM and close to the WMH borders supports a relationship between BBB disruption and development of WMHs. PMID:26205374

    A woman had been followed since 1957 for acute phase Chagas disease. Parasitological and serological tests were positive, and treatment included benznidazole in 1974. Following treatment, parasitological test results were negative and conventional serology remained positive until 1994, with subsequent discordant results (1995-1997). The results became consistently negative since 1999. She had an indeterminate chronic form until 1974. Only two minor and transitory nonspecific alterations on electrocardiogram were noted, with the last nine records normal until June 2014. This case confirms the possibility of curing chronic disease and suggests the benefit of specific treatments for preventing long-term morbidity. PMID:26516979

    The U.S. Department of Energy (DOE) has tasked MSE Technology Applications, Inc. (MSE) with evaluating the long-term stability of various commercially available sorbent materials to solidify two organic surrogate wastestreams (both volatile and nonvolatile), a volatile organic surrogate with a residual aqueous phase, an aqueous surrogate, and an aqueous surrogate with a residual organic phase. The Savannah River Site (SRS) Legacy and F-Canyon plutonium/uranium extraction (PUREX) process waste surrogates constituted the volatile organic surrogates, and various oils constituted the nonvolatile organic surrogates. The aqueous surrogates included a rainwater surrogate and an aqueous organic surrogate. MSE also evaluated the PUREX surrogate with a residual aqueous component with and without aqueous type sorbent materials. Solidification of the various surrogate wastestreams listed above was performed from 2004 to 2006 at the MSE Test Facility located in Butte, Montana. This paper summarizes the comparison of the initial liquid release test (LRT) values with LRT results obtained during subsequent sampling events in an attempt to understand and define the long-term stability characteristics for the solidified wastestreams.

    Borehole observatories developed for long-term sampling and monitoring in the subseafloor of the deep ocean must satisfy design and operation requirements that are similar to systems deployed on land. Many of these systems are used to achieve simultaneous hydrologic, geochemical and microbiological goals, requiring innovative design, installation, and operation. There are major logistical challenges for subseafloor observatories, the foremost being having to remotely access sites kilometers underwater using multiple oceanographic platforms (drill ship, surface ship, submersible, remotely-operated vehicle) and reliance on autonomous devices that are serviced only after several years. Contamination of the analytical environment is probable during installation operations, requiring vigilance during analysis for interpretation. Subseafloor observatories also require self-contained and robust instrumentation that can withstand long-term exposure to seawater at high pressures, elevated temperatures, a variety of redox conditions, and little to no access to external power. Although subseafloor borehole observatories have been in development for hydrologic monitoring for two decades, the inclusion of experimentation to examine the deep biosphere in the marine subsurface has only recently been developed. Results from some of the first microbial colonization experiments in young basaltic rocks on the eastern flank of the Juan de Fuca Ridge demonstrate in situ microbial-mineral interactions that can be identified using complementary geochemical and microbiological techniques. Mineral surfaces were first colonized by iron oxidizing bacteria, and as fluid composition changed, the microbial community became dominated by Firmicutes bacteria, some of which are phylogenetically similar to microbial communities observed in the terrestrial deep biosphere.

    Muscle-in-vein conduits are used alternatively to nerve grafts for bridging nerve defects. The purpose of this study was to examine short- and long-term regeneration results after digital nerve reconstruction with muscle-in-vein conduits. Static and moving two-point discriminations and Semmes-Weinstein Monofilaments were used to evaluate sensory recovery 6–12 months and 14–35 months after repair of digital nerves with muscle-in-vein in 7 cases. Both follow-ups were performed after clinical signs of progressing regeneration disappeared. In 4 of 7 cases, a further recovery of both two-point discriminations and in another case of only the static two-point discrimination of 1–3 mm could be found between the short-term and long-term follow-up examination. Moreover, a late recovery of both two-point discriminations was demonstrated in another case. Four of 7 cases showed a sensory improvement by one Semmes-Weinstein Monofilaments. This pilot study suggests that sensory recovery still takes place even when clinical signs of progressing regeneration disappear. PMID:26692868

    The dynamic self-regulating prosthesis (protesi autoregolantesi dinamica, PAD) is a double-layered prosthesi, in use since 1992 in inguinal hernia repair. In 1999, we published the short-term results on 500 patients and herein we report the long-term follow-up. Five hundred eighty-five PAD procedures were performed on 500 adult male, unselected patients. Hernias were unilateral in 415 patients, were bilateral in 85 patients, were direct in 197 patients (33.7%), were indirect in 269 patients (46.0%), and were combined in 119 patients (20.3%). Four hundred sixty-four patients were alive at the follow-up period of minimum 5 years, whereas 36 died (7.2%) of causes unrelated to the hernia. No information was available on 73 patients (14.6%). Therefore, the follow-up was consisted of 391 patients (78.2%) with 469 hernias. The recurrence and testicular atrophy rates were nil. Three patients (0.77%) presented chronic pain and 18 (4.6%) suffered persistent discomfort or paresthesia. A hydrocoele was observed in one patient (0.2%). The long-term data confirm the efficacy of the dynamic self-regulating posthesis hernioplasty. We propose it as a standard of care in all cases of primary inguinal hernia in adult males, retaining it as a definitive and comfortable solution.

    Purpose The aim of this study was to report the long-term outcome and the failure mechanism of cementless total hip arthroplasty (THA) using hydroxyapatite (HA)-coated acetabular cup. Materials and Methods From January 1992 to May 1994, a total of 123 consecutive cementless primary THAs were performed using a HA-coated acetabular cup with metal-on-polyethylene articulation. We retrospectively evaluated 66 hips available for follow-up at a mean 18.3 years (range, 10.4-23.6 years). The survival analysis was performed by the Kaplan-Meier method. We defined end point as any failure that required a reoperation of acetabular component. Results Thirty-nine of 66 hips (59.1%) were defined as a failure for progressive acetabular osteolysis or aseptic loosening of the cup. Acetabular osteolysis was observed in 47 hips (71.2%) and 33 hips (50.0%) were revised because of cup loosening. The Kaplan-Meier method showed the survival rate of the acetabular cup to be 46.3% at 15 years and 34.8% at 20 years for any failure that required a reoperation of acetabular component. Conclusion The long-term survival rate of THA using HA-coated acetabular cup was unsatisfactory, and it was attributed to vulnerable property of HA coating and progressive osteolysis. PMID:27536628

    Development of six large nodules of solid tissue after bilateral human fetal striatal transplantation in four Huntington's disease patients has raised concern about the safety of this experimental therapy in our setting. We investigated by serial MRI-based volumetric analysis the growth behaviour of such grafts. After 33-73 months from transplantation the size of five grafts was stable and one graft showed a mild decrease in size. Signs neither of intracranial hypertension nor of adjuctive focal neurological deficit have ever been observed. This supports long-term safety of the grafting procedure at our Institution.

    Abstract Long-term studies demonstrating the effect of pioglitazone use on primary prevention of ischemic cerebrovascular disease in older people with type 2 diabetes mellitus are lacking. This study investigated the relationship between pioglitazone use and first attack of ischemic cerebrovascular disease in Taiwan. We conducted a case-control study using the database of the Taiwan National Health Insurance Program. There were 2359 type 2 diabetic subjects aged ≥65 years with newly diagnosed ischemic cerebrovascular disease from 2005 to 2011 as the case group and 4592 sex- and age-matched, randomly selected type 2 diabetic subjects aged ≥65 years without ischemic cerebrovascular disease as the control group. The odds ratio (OR) with 95% confidence interval (CI) of ischemic cerebrovascular disease associated with pioglitazone use was measured by the multivariable unconditional logistic regression model. After adjustment for confounding factors, the multivariable logistic regression analysis disclosed that the adjusted ORs of first attack of ischemic cerebrovascular disease associated with cumulative duration of using pioglitazone were 3.34 for <1 year (95% CI 2.59–4.31), 2.53 for 1 to 2 years (95% CI 1.56–4.10), 2.20 for 2 to 3 years (95% CI 1.05–4.64), and 1.09 for ≥3 years (95% CI 0.55–2.15), respectively. Our findings suggest that pioglitazone use does not have a protective effect on primary prevention for ischemic cerebrovascular disease among older people with type 2 diabetes mellitus during the first 3 years of use. Whether using pioglitazone for >3 years would have primary prevention for ischemic cerebrovascular disease needs a long-term research to prove. PMID:27495077

    The increased risk of cardiac valve disease in patients treated for Parkinson's disease with cabergoline has raised concerns about the safety of treatment with ergot-derived dopamine agonists in patients with endocrine diseases, especially prolactinoma. Six cross-sectional studies have been published recently, of which five studies do not show an association between the treatment of prolactinoma with cabergoline during 45-79 months and clinically relevant valvular regurgitation in a total of 413 patients. Nonetheless, concern is raised because the use of cabergoline was associated in one study with an increased prevalence of moderate tricuspid regurgitation, and in two other studies with mild tricuspid regurgitation. Furthermore, the use of cabergoline was associated with increased frequencies of valvular thickening, calcifications and increased mitral tenting area. At present, the clinical relevance of these findings is still uncertain, but concern is raised with respect to the safety of the use of cabergoline in the long-term treatment of prolactinomas. Echocardiographic evaluation should be considered in patients, who require long-term treatment with cabergoline, especially in high doses. There is a need for larger, preferably prospective, studies with careful echocardiographic assessment and with longer durations of follow-up than the currently available studies.

    Amyloid beta (Aβ) plays a major role in Alzheimer's disease (AD), and neuroinflammatory processes mediated by Aβ plaque-induced microglial cells and astrocytes contribute to AD pathogenesis. The present study examined human placenta amniotic membrane-derived mesenchymal stem cells (AMSCs), which have potent immunomodulatory and paracrine effects in a Tg2576 (APPswe) transgenic mouse model of AD. AMSCs secreted high levels of transforming growth factor-β under in vitro inflammatory environment conditions. Six weeks after the intravenous injection of AMSCs, APPswe mice showed evidence of improved spatial learning, which significantly correlated with the observation of fewer Aβ plaques in brain. The number of ED1-positive phagocytic microglial cells associated with Aβ plaques was higher in AMSC-injected mice than in phosphate-buffered saline-injected mice, and the level of Aβ-degrading enzymes (matrix metallopeptidase-9 and insulin-degrading enzyme) was also significantly higher. Furthermore, the level of proinflammatory cytokines, interleukin-1 and tumor necrosis factor-α, was lower and that of anti-inflammatory cytokines, interleukin-10 and transforming growth factor-β, was higher in AMSC-injected mice than phosphate-buffered saline-injected mice. These effects lasted until 12 weeks after AMSC injection. Taken together, these results collectively suggest that injection of AMSCs might show significant long-lasting improvement in AD pathology and memory function via immunomodulatory and paracrine mechanisms.

    Anderson-Fabry disease is a potentially life-threatening hereditary lysosomal storage disorder taking origin in over 1,000 known pathogenic mutations in the alpha-galactosidase A encoding gene. Over the past 15 years, intravenous replacement therapy of the deficient alpha agalsidase A enzyme has been well-established retarding the progression of a multisystemic disease and organ involvement. Despite this innovative treatment approach, premature deaths still do occur. The response to enzyme replacement therapy (ERT) varies considerably and appears to depend on gender, genotype (classic or later onset/non-classic), stage of disease or age and agalsidase inhibition by anti-agalsidase antibodies. Early ERT treatment at young age, a personalized approach, and adjunctive therapies for specific disease manifestations appear to impact on prognosis and are currently favored with the expectance of more effective intravenous and oral treatments in the short future.

    Treatment for human papillomavirus (HPV)-associated anal canal disease has been unsatisfactory. The objective of our study was to determine the treatment outcome in our cohort with anal HPV disease. Overall, 181 patients were evaluated over a median period of 19.1 months (range = 2.8-125.5). Eighty-eight patients (48.6%) with high-grade anal intraepithelial neoplasia (AIN) and 82 patients (45.3%) with low-grade AIN underwent treatment. One hundred and forty-one patients (77.9%) received laser ablative treatment as an outpatient procedure. The treatment yielded cure, defined as a disease-free state at 12 months after treatment, in 63.0% (114/181). Median time to cure for the cohort was 31.5 months (95% confidence interval: 23.0-40.0). Treatment outcome showed no evidence of being affected by age, sexual preference, history of smoking or presence of high-grade disease. Median time to cure was significantly affected by a positive HIV status (P = 0.02) and the extent (volume) of the disease (P = 0.01). Contrary to the current view that treatment of HPV-related anal disease is difficult, unrewarding due to recurrences and may lead to substantial morbidity, we demonstrate that effective treatment is possible for both low- and high-grade AIN. These findings should help with the general desire to introduce screening for AIN for at-risk groups. PMID:18574114

    In Duchenne muscular dystrophy (DMD) patients and the mouse model of DMD, mdx, dystrophin deficiency causes a decrease and mislocalization of muscle-specific neuronal nitric oxide synthase (nNOSμ), leading to functional impairments. Previous studies have shown that nitric oxide (NO) donation associated with anti-inflammatory action has beneficial effects in dystrophic mouse models. In this study, we have systematically investigated the effects of naproxcinod, an NO-donating naproxen derivative, on the skeletal and cardiac disease phenotype in mdx mice. Four-week-old mdx and C57BL/10 mice were treated with four different concentrations (0, 10, 21 and 41 mg/kg) of naproxcinod and 0.9 mg/kg of prednisolone in their food for 9 months. All mice were subjected to twice-weekly treadmill sessions, and functional and behavioral parameters were measured at 3, 6 and 9 months of treatment. In addition, we evaluated in vitro force contraction, optical imaging of inflammation, echocardiography and blood pressure (BP) at the 9-month endpoint prior to sacrifice. We found that naproxcinod treatment at 21 mg/kg resulted in significant improvement in hindlimb grip strength and a 30% decrease in inflammation in the fore- and hindlimbs of mdx mice. Furthermore, we found significant improvement in heart function, as evidenced by improved fraction shortening, ejection fraction and systolic BP. In addition, the long-term detrimental effects of prednisolone typically seen in mdx skeletal and heart function were not observed at the effective dose of naproxcinod. In conclusion, our results indicate that naproxcinod has significant potential as a safe therapeutic option for the treatment of muscular dystrophies. PMID:24463621

    A tooth with primary endodontic disease that demonstrates a periodontal defect might be extracted because of misdiagnosis as severe periodontal disease or a vertical root fracture. The aim of this case report was to demonstrate the long-term survival of endodontically treated teeth, which had been initially considered unsavable. With meticulous evaluation including the patient's dental history, clinical and radiographic examinations, teeth with primary endodontic lesions could be differentiated and saved after proper root canal treatment. Pain history, vitality test, and radiographic examinations, as well as a general periodontal condition check with periodontal probing on an affected tooth, might be the key methods to differentiate endodontic pathosis from that of periodontal disease.

    Background: We investigated adverse outcomes for people with acute rheumatic fever (ARF) and rheumatic heart disease (RHD) and the effect of comorbidities and demographic factors on these outcomes. Methods: Using linked data (RHD register, hospital, and mortality data) for residents of the Northern Territory of Australia, we calculated ARF recurrence rates, rates of progression from ARF to RHD to severe RHD, RHD complication rates (heart failure, endocarditis, stroke, and atrial fibrillation), and mortality rates for 572 individuals diagnosed with ARF and 1248 with RHD in 1997 to 2013 (94.9% Indigenous). Results: ARF recurrence was highest (incidence, 3.7 per 100 person-years) in the first year after the initial ARF episode, but low-level risk persisted for >10 years. Progression to RHD was also highest (incidence, 35.9) in the first year, almost 10 times higher than ARF recurrence. The median age at RHD diagnosis in Indigenous people was young, especially among males (17 years). The development of complications was highest in the first year after RHD diagnosis: heart failure incidence rate per 100 person-years, 9.09; atrial fibrillation, 4.70; endocarditis, 1.00; and stroke, 0.58. Mortality was higher among Indigenous than non-Indigenous RHD patients (hazard ratio, 6.55; 95% confidence interval, 2.45–17.51), of which 28% was explained by comorbid renal failure and hazardous alcohol use. RHD complications and mortality rates were higher for urban than for remote residents. Conclusions: This study provides important new prognostic information for ARF/RHD. The residual Indigenous survival disparity in RHD patients, which persisted after accounting for comorbidities, suggests that other factors contribute to mortality, warranting further research.

    The treatment of late-onset Pompe disease (LOPD) relies on enzyme replacement therapy (ERT) and physiotherapy but the most appropriate exercise program is not yet established. Whole-body vibration training (WBVT) has showed promising results, improving motor performances in various populations. Our aim is to assess the effects of WBVT performed by two LOPD patients in addition to ERT and physiotherapy. A side-alternating WBVT lasting 2 years; clinical assessments included: manual muscle testing (MRC sumscore), knee extension and arm flection isometric strength (multi-muscle tester M3diagnos), timed function tests (10 m walking, standing-up from chair, ascending 4-steps), 6 min walking (6 MWT), motor disability (Walton Gardner-Medwin scale), pulmonary function. Follow-up evaluations performed for 9 years since ERT start (pre-WBVT and post-WBVT) are reported for comparison. MRC sumscore improved in both patients (Pt.1:41 → 48, Pt.2:42 → 47) as isometric strength of knee extension (Pt.1: + 62 %, Pt.2: + 26 %) and arm flection (Pt.1: + 88 %, Pt.2: + 66 %), 6 MWT improved in Pt.1 (+75 m). Timed function tests did not greatly change. Patients reported no significant CK elevation or WBVT-related complaints. WBVT may be safely used in LOPD and seems to moderately boost muscle strength in patients receiving ERT and physiotherapy for more than 3 years. Larger cohorts should be studied to better assess WBVT potential as adjunctive exercise tool in LOPD. PMID:27193587

  10. Anti-inflammatory/antioxidant use in long-term maintenance cancer therapy: a new therapeutic approach to disease progression and recurrence

    PubMed Central

    2014-01-01

    The chronic, progressive clinical characteristics of many adult solid tumor malignancies suggest that a more effective therapeutic approach to cancer management may require long-term intervention using nontoxic systemic agents that block critical components of abnormal tumor physiology. Two highly promising systemic targets common to the development, progression and recurrence of many common cancers are dysregulated inflammatory and oxidation/reduction (redox) pathways. Compelling clinical data support the use of anti-inflammatory and antioxidant agents as a therapeutic modality for long-term use in patients diagnosed with several common cancers, including colon cancer and breast cancer. The therapeutic paradigm presented in this paper is the product of a synthesis of what is currently understood about the biological effects of inflammation and oxidative stress that contribute to tumorigenesis, disease progression and recurrence as well as results obtained from research on the use of prophylactics with anti-inflammatory or antioxidant properties in cancer prevention and treatment.

    This document reports the long-term testing results from an extended GATEWAY project that was first reported in “Demonstration Assessment of Light-Emitting Diode (LED) Roadway Lighting at the I-35W Bridge, in Minneapolis, MN,” August 2009. That original report presented the results of lighting the newly reconstructed I 35W Bridge using LEDs in place of conventional high-pressure sodium (HPS) roadway luminaires, comparing energy use and illuminance levels with a simulated baseline condition.

    A wide range of viral, bacterial, and protozoal diseases pose risk to long-term tropical travelers. Risk varies geographically and with lifestyle. For some infections, risk increases with duration of stay, coming to resemble that of the local population. Risk management strategies include vaccination, chemoprophylaxis, avoidance measures, and screening, where appropriate. Vaccination against hepatitis A and B, typhoid, and rabies is recommended for all long-term travelers to (sub-)tropical areas. Lowering of the vaccination threshold for Japanese encephalitis is suggested. Meningococcal disease is rare in travelers, but vaccination is safe and acceptable. The efficacy of Bacillus Calmette-Guérin (BCG) is uncertain; immunological testing avoids BCG's confounding of tuberculin testing. Diarrhea is common, and self-treatment may be recommended. Sexually transmitted infections including human immunodeficiency virus (HIV) are serious risks; education, screening, and HIV postexposure prophylaxis following involuntary exposure are recommended. Many infections are chronic or asymptomatic, and appropriate screening is recommended on return or after prolonged exposure.

    In epidemiology, it is very important to estimate the baseline incidence of infectious diseases. From this baseline, the epidemic threshold can be derived as a clue to recognize an excess incidence, i.e. to detect an epidemic by mathematical methods. Nevertheless, a problem is posed by the fact that the incidence may vary during the year, as a rule, in a season dependent manner. To model the incidence of a disease, some authors use seasonal trend models. For instance, Serfling applies the sine function with a phase shift and amplitude. A similar model based on the analysis of variance with kernel smoothing and Serfling's higher order models, i.e. models composed of multiple sine-cosine function pairs with a variably long period, will be presented below. Serfling's model uses a long-term linear trend, but the linearity may not be always acceptable. Therefore, a more complex, long-term trend estimation will also be addressed, using different smoothing methods. In addition, the issue of the time unit (mostly a week) used in describing the incidence is discussed. PMID:26841150

    The purpose of this study was to review the long-term outcomes of a previously reported prospective series of 46 type III acromioclavicular dislocations. These were treated surgically with temporary fixation of the acromioclavicular joint with wires, repair of the acromioclavicular ligaments, and overlapped suture of the deltoid and trapezius muscles. Of the 46 patients, one had died, four could not be traced, and three declined to return for follow-up, leaving 38 patients in the study. There were 36 men and two women, with a mean age at follow-up of 57.3 years (41 to 71). The mean follow-up was 24.2 years (21 to 26). Patients were evaluated using the Imatani and University of California, Los Angeles (UCLA) scoring systems. Their subjective status was assessed using the Disabilities of the Arm, Shoulder and Hand and Simple Shoulder Test questionnaires, and a visual analogue scale for patient satisfaction. The examination included radiographs of the shoulder. At a follow-up of 21 years, the results were satisfactory in 35 (92.1%) patients and unsatisfactory in three (7.9%). In total, 35 patients (92.1%) reported no pain, one slight pain, and two moderate pain. All except two patients had a full range of shoulder movement compared with the opposite side. Unsatisfactory results were the result of early redisplacement in two patients, and osteoarthritis without redisplacement in one. According to the Imatani and UCLA scores, there was no difference between the operated shoulder and the opposite shoulder (p > 0.05). Given the same situation, 35 (92.1%) patients would opt for the same surgical treatment again. Operative treatment of type III acromioclavicular joint injuries produces satisfactory long-term results.

    Despite increasing evidence that burn injuries can result in multiple psychological sequelae, little is known about the long-term psychosocial adjustment to burns sustained in a major bushfire. The aim of the present study was to assess long-term psychological distress and health-related quality of life in Australian burns patients as a result of the 2009 Black Saturday bushfires. Eight male and five female burns patients with a mean age of 53.92 (SD = 11.82) years who received treatment at a statewide burns service participated in the study. A battery of standardized questionnaires was administered to assess general psychological distress, burns-specific and generic health-related quality of life, alcohol use, and specific psychological symptoms of posttraumatic stress disorder, depression, and anxiety. The results revealed that more than 3 years after Black Saturday 33% of the burns patients still suffered "high" to "very high" levels of general distress, whereas 58% fulfilled partial or full criteria for posttraumatic stress disorder. Furthermore, participants still experienced significantly impaired physical health functioning as compared to their preinjury status including limitations in work-based activities, increased bodily pain, and lower vitality overall. The trajectory of distress varied for participants. Some individuals experienced little distress overall, whereas others displayed a decline in their stress levels over time. Notwithstanding, some patients maintained high levels of distress throughout or experienced an increase in distress at a later stage of recovery. The results point to the importance of psychosocial screening to identify distress early. Follow-up assessments are crucial to diagnose individuals with chronic or late onset of distress.

    Stroke in patients with valvular heart disease undergoing transcatheter intervention is relatively rare but associated with significant morbidity and mortality. Risks vary according to the underlying valve disease and proposed procedure. While major improvements have been made in developing and understanding the technical factors associated with intra- and peri-procedural stroke, uncertainty exists regarding the optimal antithrombotic management strategy after transcatheter heart valve intervention and the utility of routine cerebral embolic protection. Further clinical studies are warranted to minimise these complications. PMID:26384184

  17. Duodenal ulcer and gastroesophageal reflux disease today: long-term therapy--a sideways glance.

    Acid-peptic disease is widely considered conquered or controlled, future advances being refinements of existing treatments rather than radical new developments. Yet controversies remain and developments have yet to be made. DUODENAL ULCER: Daily maintenance treatment with the anti-secretory drugs, histamine H2 receptor antagonists and proton pump blockers, controls duodenal ulcer effectively, markedly reducing relapse rate at one year after treatment from about 75 percent to 15 to 20 percent (and to about 10 percent on proton pump blockers). In contrast, Helicobacter pylori eradication with a one to two week course of treatment yields prolonged remission or cure. The consequent reduction in drug costs in individual patients, however, has been exceeded by increasing community use on the more expensive proton pump blockers for the treatment of gastroesophageal reflux disease. The marked decline in elective surgery since the introduction of histamine H2 receptor antagonists is commonly attributed to the power of these drugs. The fall, however, had started much earlier, indicating that the decline is due to changing natural history. In contrast, complication rates remain unaltered. An increasing proportion of newly diagnosed duodenal ulcer patients are elderly, and more of them now present for the first time with complications (in this center, about 40 percent), which consequently cannot be forestalled. Thus, duodenal ulcer disease is likely to remain a problem and in many will be a serious illness. GASTROESOPHAGEAL REFLUX DISEASE: The proton pump blockers have revolutionized the treatment of gastroesophageal reflux disease. In clinical trials they have proven markedly superior to the histamine H2 receptor antagonists in healing (at eight weeks, 80 to 90 percent vs. 50 to 60 percent), symptom relief, prevention of relapse on maintenance therapy and cost-effectiveness. However, several issues remain. The prevalence of gastroesophageal reflux disease seems to be rising

    Objective Umeclidinium bromide (UMEC) 62.5 μg is a long-acting muscarinic antagonist (LAMA) that is administered once daily via inhalation for chronic obstructive pulmonary disease (COPD) treatment. The objective of this study was to evaluate the safety and tolerability of long-term treatment with UMEC 125 μg in Japanese patients with COPD. Methods This was a 52 week, multicenter, open-label study to evaluate the safety and tolerability of UMEC 125 μg once daily delivered via a novel dry powder inhaler (nDPI) in Japanese patients with COPD. The primary endpoint was the incidence and severity of all adverse events (AEs) throughout the 52 week treatment period. Clinical trial registration number ClinicalTrials.gov identifier is NCT01702363. Results A total of 153 patients were enrolled in the study. Of these, 131 patients started treatment with UMEC 125 μg, and 111 patients (85%) completed the study. AEs did not differ greatly in incidence over the various time periods (Weeks 0 to 12, 13 to 24, 25 to 36, and 37 to 52 of treatment) and did not increase with continued treatment. The incidence of drug-related AEs associated with the pharmacological effects of LAMAs (including constipation, blurred vision, and thirst) was low. Serious adverse events (SAEs) during the treatment period were reported in 17 patients (13%). SAEs reported in more than one patient were COPD exacerbation and pneumonia (3 patients each, 2%). One SAE of angina pectoris was considered to be drug related. No fatalities were reported during this study. Conclusions No new AEs were identified beyond those attributable to the pharmacological effects of LAMAs. UMEC 125 μg was well tolerated over 52 weeks of treatment in Japanese patients with COPD.

    We examined the impact of multidisciplinary clinical management of the Parkinson's Disease Research, Education, and Clinical Center program on Parkinson's disease progression. Initial and follow-up scores on the Part III Motor Examination subscale of the Unified Parkinson's Disease Rating Scale (UPDRS) were examined. Overall, 37 (75.5%) of the 49 patients demonstrated stable or improved UPDRS motor scores at 1- to 3-year follow-up; in the 1-year group (n = 28), 22 patients (78.6%) improved, while 6 (21.4%) worsened. In the 2-year group (n = 15), 10 (66.7%) improved, while 5 (33.3%) worsened. In the 3-year group (n = 6), 5 (83.3%) improved, while 1 (16.7%) worsened. Multidisciplinary interventions included neurology (95.9% of patients), physiatry (93.9%), nursing (87.8%), psychology (42.9%), medication changes (59.2% increases, 18.4% decreases), rehabilitation therapies (physical, occupational, speech-language, 67.3%), functional diagnostic testing (18.4%), support group (16.3%), home exercise instruction (85.7%), and disease and wellness education (81.6%). Improved and worsened patients did not significantly differ on the individual program components. Clinical implications and study limitations are discussed.

    Adults with stroke at a young age (18-50 years) remain at an increased risk of death for decades. It is unclear what cause underlies this long-term excess mortality and whether this is sex and time specific. Therefore, we investigated sex-specific temporal changes in cause of death after transient ischemic attack or ischemic stroke in young adults aged 18 to 50 years. We included all 845 consecutive 30-day survivors, of a first-ever transient ischemic attack (n=261) or ischemic stroke (n=584), admitted to our hospital between 1980 and 2010. Survival status was assessed at April 1, 2013. Observed cause-specific mortality was compared with expected mortality, derived from mortality rates in the general population with similar age, sex, and calendar-year characteristics. During a median follow-up of 9.2 years, 146 patients (17.3%) died, such that 29 years of life was lost by each individual. For all causes of death, observed mortality exceeded expected mortality. The absolute excess risk of death was for 74% attributable to a vascular cause (absolute excess risk, 2.8 per 1000 person-years [95% confidence interval, 1.8-4.1] for stroke and absolute excess risk, 4.3 per 1000 person-years [95% confidence interval, 2.9-5.9] for other vascular causes). The absolute excess risk was highest between 10 and 15 years after stroke and this peak was most pronounced in men and mainly attributable to vascular death. Long-term excess death after stroke in young adults is mainly attributable to a vascular cause and most pronounced in men. Attempts to reduce the risk of vascular disease after stroke in young adults should extend beyond the acute phase into the long term.

    Few studies have examined long-term effects of statin therapy on kidney diseases. The objective of this study was to determine the association of statin use with incidence of acute and chronic kidney diseases after prolonged follow-up. In this retrospective cohort study, we analyzed data from the San Antonio area military health care system from October 2003 through March 2012. Statin users were propensity score matched to nonusers using 82 baseline characteristics including demographics, co-morbidities, medications, and health care utilization. Study outcomes were acute kidney injury, chronic kidney disease (CKD), and nephritis/nephrosis/renal sclerosis. Of the 43,438 subjects included, we propensity score matched 6,342 statin users with 6,342 nonusers. Statin users had greater odds of acute kidney injury (odds ratio [OR] 1.30, 95% confidence interval [CI] 1.14 to 1.48), CKD (OR 1.36, 95% CI 1.22 to 1.52), and nephritis/nephrosis/renal sclerosis (OR 1.35, 95% CI 1.05 to 1.73). In a subset of patients without co-morbidities, the association of statin use with CKD remained significant (OR 1.53, 95% CI 1.27 to 1.85). In a secondary analysis, adjusting for diseases/conditions that developed during follow-up weakened this association. In conclusion, statin use is associated with increased incidence of acute and chronic kidney disease. These findings are cautionary and suggest that long-term effects of statins in real-life patients may differ from shorter term effects in selected clinical trial populations. PMID:26742473

    Coca-Cola was invented in May 1886 in Atlanta, Georgia by a pharmacist who, by accident or design, mixed carbonated water with the syrup of sugar, phosphoric acid, caffeine, and other natural flavors to create what is known as "the world's favorite soft drink." Coca-Cola is currently sold in more than 200 countries and in early 2000, the company sold its 10 billionth unit case of Coca-Cola branded products. Given the worldwide consumption of Coca-Cola, a project of experimental bioassays to study its long-term effects when administered as substitute for drinking water on male and female Sprague-Dawley rats was planned and executed. The objective of the project was to study whether and how long-term consumption of Coca-Cola affects the basic tumorigram of test animals. The bioassays were performed on rats beginning at different ages, namely: (a) on males and females exposed since embryonic life or from 7 weeks of age; and (b) on males and females exposed from 30, 39, or 55 weeks of age. Overall, the project included 1999 rats. During the biophase, data were collected on fluid and feed consumption, body weight, and survival. Animals were kept under observation until spontaneous death and underwent complete necropsy. The results indicate: (a) an increase in body weight in all treated animals; (b) a statistically significant increase of the incidence in females, both breeders and offspring, bearing malignant mammary tumors; (c) a statistically significant increase in the incidence of exocrine ademonas of the pancreas in both male and female breeders and offspring; and (d) an increased incidence, albeit not statistically significant, of pancreatic islet cell carcinomas in females, a malignant tumor which occurs very rarely in our historical controls. On the basis of the results of this study, excessive consumption of regular soft-drinks should be generally discouraged, in particular for children and adolescents.

    Purpose: To report long-term results of a bladder preservation strategy for muscle-invasive bladder cancer (MIBC) using external beam radiation therapy and brachytherapy/interstitial radiation therapy (IRT). Methods and Materials: Between May 1989 and October 2011, 192 selected patients with MIBC were treated with a combined regimen of preoperative external beam radiation therapy and subsequent surgical exploration with or without partial cystectomy and insertion of source carrier tubes for afterloading IRT using low dose rate and pulsed dose rate. Data for oncologic and functional outcomes were prospectively collected. The primary endpoints were local recurrence-free survival (LRFS), bladder function preservation survival, and salvage cystectomy-free survival. The endpoints were constructed according to the Kaplan-Meier method. Results: The mean follow-up period was 105.5 months. The LRFS rate was 80% and 73% at 5 and 10 years, respectively. Salvage cystectomy-free survival at 5 and 10 years was 93% and 85%. The 5- and 10-year overall survival rates were 65% and 46%, whereas cancer-specific survival at 5 and 10 years was 75% and 67%. The distant metastases-free survival rate was 76% and 69% at 5 and 10 years. Multivariate analysis revealed no independent predictors of LRFS. Radiation Therapy Oncology Group grade ≥3 late bladder and rectum toxicity were recorded in 11 patients (5.7%) and 2 patients (1%), respectively. Conclusions: A multimodality bladder-sparing regimen using IRT offers excellent long-term oncologic outcome in selected patients with MIBC. The late toxicity rate is low, and the majority of patients preserve their functional bladder.

    The spinal cord has the ability to regenerate but the microenvironment generated after trauma reduces that capacity. An increase in Src family kinase (SFK) activity has been implicated in neuropathological conditions associated with central nervous system trauma. Therefore, we hypothesized that a decrease in SFK activation by a long-term treatment with 4-amino-5-(4-chlorophenyl)-7-(t-butyl)pyrazolo[3,4-d]pyramidine (PP2), a selective SFK inhibitor, after spinal cord contusion with the New York University (NYU) impactor device would generate a permissive environment that improves axonal sprouting and/or behavioral activity. Results demonstrated that long-term blockade of SFK activation with PP2 increases locomotor activity at 7, 14, 21 and 28 days post-injury in the Basso, Beattie, and Bresnahan open field test, round and square beam crossing tests. In addition, an increase in white matter spared tissue and serotonin fiber density was observed in animals treated with PP2. However, blockade of SFK activity did not change the astrocytic response or infiltration of cells from the immune system at 28 days post-injury. Moreover, a reduced SFK activity with PP2 diminished Ephexin (a guanine nucleotide exchange factor) phosphorylation in the acute phase (4 days post-injury) after trauma. Together, these findings suggest a potential role of SFK in the regulation of spared tissue and/or axonal outgrowth that may result in functional locomotor recovery during the pathophysiology generated after spinal cord injury. Our study also points out that ephexin1 phosphorylation (activation) by SFK action may be involved in the repulsive microenvironment generated after spinal cord injury. PMID:25657738

    The aim of this study was to investigate speech and language development after long-term cochlear implantation in children with bony labyrinth malformations (BLMs) and to present the surgical findings in this group of patients. The auditory and linguistic skills of 21 children who had BLM were assessed in this study. They were implanted between 1998 and 2009. Twenty-two sex-matched and age-matched implantees without BLM were evaluated as the control group. To compare speech perception and speech intelligibility between the groups, the categories of auditory performance (CAP) test and speech intelligibility rating (SIR) test, respectively, were administered. The Turkish version of the Test of Early Language Development (TELD-3-T) was administered to evaluate and compare the linguistic skills of the groups. Surgical findings and complications were also analyzed. Implanted anomalies were common cavity in five patients, incomplete partition type 1 in 5 patients, and incomplete partition type 2 in 11 patients. The CAP and SIR scores were significantly higher in the control group (p < 0.05), but the TELD-3-T test scores were comparable among the groups (p > 0.05). Based on the specific type of malformation, the CAP and SIR scores were comparable between the subgroups (p > 0.05). No perioperative complications occurred in the control group. However, various perioperative complications (gusher, etc.) and surgical difficulty occurred in the anomaly group. The malformation group had unsatisfactory results with regard to speech perception skills; however, this group and the non-anomalous group exhibited comparable long-term results on linguistic development.

    Acromegaly is a rare disease most often caused by the prolonged secretion of excess growth hormone from a pituitary adenoma. The disease is associated with multiple significant comorbidities and increased mortality. The delay to diagnosis is often long. This may be because of low disease awareness among health care professionals, the insidious onset of differentiating features, and because patients are likely to present with complaints typical of other conditions more frequently seen in primary care. Early identification of acromegaly facilitates prompt treatment initiation and may minimize the permanent effects of excess growth hormone. The primary treatment for many patients will be pituitary surgery, although not all patients will be eligible for surgery or achieve a surgical cure. If biochemical control is not achieved following surgery, other treatment options include medical therapy and radiation therapy. Improved biochemical control may only alleviate rather than reverse the associated comorbidities. Thus, lifelong monitoring of patient health is needed, with particular attention to the management of cardiovascular risk factors. It is additionally important to consider the impact of both disease and treatment on patients’ quality of life and minimize that impact where possible, but particularly for chronic therapies. For the majority of patients, chronic therapy is likely to include somatostatin analog injections. In some circumstances, it may be possible to extend the dosing interval of the analog once good biochemical control is achieved. Additional convenience may be gained from the possibility of self-/partner administration of treatment or administration of treatment by a health care professional at home. Overall, it is clear that the care of patients with acromegaly requires a highly coordinated approach involving numerous specialties (eg, endocrinology, surgery, cardiology). Further, patients’ needs must be at the core of management and every

    Metastasis to the adrenal glands is a relatively frequent observation at autopsy of patients that have succumbed to cancer. Long-term disease-free survival has been reported in patients following the resection of solitary adrenal metastasis resulting from colorectal cancer. In addition, following primary resection for colorectal cancer, solitary metastasis to the adrenal glands is rare, even in outpatients at routine follow-ups. Therefore, adrenal metastasis is usually detected in combination with multiple synchronous metastases at other sites in the terminal stages of cancer. Between 1998 and 2002, 3 patients with adrenal metastasis and other synchronous metastatic sites underwent surgery for adrenal metastasis at the Department of Gastroenterological Surgery at Osaka University. The other synchronous metastatic sites observed in the 3 patients consisted of lung and para-aortic lymph nodes. In total, 2 out of the 3 patients experienced long-term disease-free survival for >5 years following surgery and 1 patient underwent curative resection for recurrence of metastases in the liver and right adrenal gland 79 months subsequent to the initial resection for adrenal metastasis. All 3 patients survived for >90 months. In conclusion, aggressive surgical resection for adrenal metastasis and other metastatic sites resulting from colorectal cancer may result in a survival benefit in selected patients. PMID:27602101

    Transtracheal administration of oxygen is a new technique for long term treatment. Twenty patients with hypoxaemia due to chronic obstructive airways disease were studied while receiving oxygen through a microcatheter inserted percutaneously into the trachea. By bypassing most of the dead space and avoiding oxygen wastage at the face this method of delivery reduced oxygen requirements by roughly half compared with delivery through nasal cannulas, thus reducing costs and facilitating portable treatment. Twelve of these patients continued to use the system for up to 13 months in preference to using nasal cannulas. Two important complications were a staphylococcal infection and a fractured catheter. Transtracheal oxygen reduced breathlessness and helped patients with routine daily activities. Transtracheal administration of oxygen is a practical method of treatment which may have an important role in rehabilitating patients with chronic lung disease. Images p112-a PMID:3089412

    Purpose: To evaluate the long-term efficacy and toxicity of definitive radiochemotherapy for solitary lymph node metastasis after curative surgery of esophageal cancer. Methods and Materials: We performed a retrospective review of 35 patients who underwent definitive radiochemotherapy at Tohoku University Hospital between 2000 and 2009 for solitary lymph node metastasis after curative esophagectomy with lymph node dissection for esophageal cancer. Radiotherapy doses ranged from 60 to 66 Gy (median, 60 Gy). Concurrent chemotherapy was platinum based in all patients. The endpoints of the present study were overall survival, cause-specific survival, progression-free survival, irradiated-field control, overall tumor response, and prognostic factors. Results: The median observation period for survivors was 70.0 months. The 5-year overall survival was 39.2% (median survival, 39.0 months). The 5-year cause-specific survival, progression-free survival, and irradiated-field control were 43.3%, 31.0% and 59.9%, respectively. Metastatic lesion, size of the metastatic lymph node, and performance status before radiochemotherapy were significantly correlated with prognosis. Complete response and partial response were observed in 22.9% and 57.1% of the patients, respectively. There was no Grade 3 or higher adverse effect based on theCommon Terminology Criteria for Adverse Events (CTCAE v3.0) in the late phase. Conclusions: Based on our study findings, approximately 40% of patients with solitary lymph node metastasis after curative resection for esophageal cancer have a chance of long-term survival with definitive radiochemotherapy.

    The Italian Tamoxifen Anastrozole (ITA) trial investigated the efficacy of switching to anastrozole for women who were already on adjuvant tamoxifen since 2-3years. Relapse-free survival (RFS) was the primary end-point; event-free survival (EFS), overall survival (OS) and safety were secondary end-points. Herein, we report an update on the long term results of this trial. At a median follow-up time of 128 months (range 14-168 months), 94 events have been recorded in the tamoxifen group compared with 71 events in the anastrozole group (hazard ratio (HR)=0.71; 95% confidence interval (CI), 0.52-0.97; p=0.03). RFS was also significantly longer in the anastrozole group (HR=0.64; 95% CI, 0.44-0.94; p=0.023); no statistically significant difference between study arms concerning OS was shown, but the trial was not powered enough in respect to this end-point. The incidence of serious adverse events (SAE) like bone fractures was comparable (four in each arm), while gynaecological problems were still significantly more numerous among the women continued on tamoxifen (21 patients developed a SAE in this group, including eight endometrial cancers, compared to three patients who suffered from a SAE, including one endometrial cancer, in the anastrozole group: p<0.000). Present data confirm that switch is safe and can provide long-term gain in terms both of RFS and of EFS, which persists even several years since treatment discontinuation.

    Since January 1994, heroin-assisted treatment for opiate addicts has been available in Switzerland. This is the first report of the long-term effects of this form of treatment. The report examines subjects who entered a study involving medical prescription of opiates (Projekt zur ärztlichen Verschreibung von Betäubungsmitteln; PROVE) in Switzerland between January 1994 and March 1995 (n = 366). Opiates were dispensed in eight treatment centres. A follow-up was conducted 6 years after treatment entry. Two groups were assessed: clients who have continuously been on heroin-assisted treatment since entry into the PROVE study or who re-entered this treatment, and ex-clients who had discontinued heroin-assisted treatment at the time of follow-up. Two kinds of comparisons were conducted. Firstly, conditions at treatment entry were compared to 6-year follow-up outcomes, and secondly, outcomes were compared between clients still on heroin-assisted treatment and those who had been discharged. It was found that 46% of the clients still alive were on heroin-assisted treatment at the time of follow-up. A comparison of the present living conditions showed very little difference between those in treatment and those who had terminated treatment. Compared to the situation at entry, the results of the follow-up showed a significant decrease in the use of illegal substances, illegal income and most other variables concerning social conditions, but they also showed an increase in unemployment and reliance on social benefits. Heroin-assisted treatment is thus efficacious in the long-term course of treatment and is still effective after termination of treatment with respect to living conditions and use of illicit substances.

    The National Service Framework (NSF) for Coronary Heart Disease, published in the UK in 2000, gave target intervention rates of 750 procedures per million population (pmp) for both percutaneous transluminal angioplasty (PTCA) and coronary artery bypass graft (CABG). This paper describes how one Regional Office of the Department of Health, with CABG and PTCA rates of around half the NSF target levels, designed a strategy to plan rationally to meet the derived population need for these procedures. A bottom-up needs assessment model was used to predict the population need for these procedures for the Eastern Region of the UK. The Excel-based model took account of the effects of demographic change, anticipated reduction in incidence of heart disease due to primary prevention programmes and the expected improvement in cardiology and cardiac surgery technologies. The model predicted that excess procedures would be required across the region over the next 20 years. Further access study modelling was used to determine the best location for additional tertiary cardiac centres. Further, a commissioning tool was produced that could compare the predicted need, including additional procedures needed to meet waiting list targets, with capacity available from a range of providers. These tools have been used successfully in the Eastern Region to increase the regional revascularization rates from 371 pmp CABG and 322 pmp PTCA in 2000 to planned rates of 453 pmp CABG and 447 pmp PTCA in 2002/2003, to recommend the building of a new tertiary cardiac centre in Essex in the next decade and to inform the commissioning of revascularization rates in three coronary heart disease networks.

    Intravenous immunoglobulin (IVIG) is used in the treatment of neuropathy. This case report presents, for the first time, a patient with severe periodontal destruction after chronic therapy with IVIG. The patient reported having extracted his maxillary anterior teeth himself due to high mobility. Clinical examination and radiographic images show a generalized and severe periodontitis. No significant alterations in genetic or microbiological features were observed. The present case suggests that periodontal disease aggravation could be considered a new adverse effect of IVIG therapy. Postulated mechanisms are immune complexes formation, complement activation, and a direct effect in osteoclasts. In conclusion, it is important that patients that will receive IVIG treatment underwent dental evaluation. PMID:25379295

    Coeliac disease is a gluten-sensitive enteropathy that develops in genetically susceptible individuals. The disease exhibits many features of an autoimmune disorder. These include the production of highly specific anti-endomysial autoantibodies directed against the enzyme tissue transglutaminase. It is well accepted that wheat-, barley- and rye-based foods should be excluded in the gluten-free diet. Although several studies report that oats ingestion is safe in this diet, the potential toxicity of oats remains controversial. In the current study, 46 coeliac patients ingested oats for 1 year and were investigated for a potential immunogenic or toxic effect. Stringent clinical monitoring of these patients was performed and none experienced adverse effects, despite ingestion of a mean of 286 g of oats each week. Routine histological analysis of intestinal biopsies showed improvement or no change in 95% of the samples examined. Furthermore, tissue transglutaminase expression in biopsy samples, determined quantitatively using the IN Cell Analyzer, was unchanged. Employing immunohistochemistry, oats ingestion was not associated with changes in intraepithelial lymphocyte numbers or with enterocyte proliferation as assessed by Ki-67 staining. Finally, despite the potential for tissue transglutaminase to interact with oats, neither endomysial nor tissue transglutaminase antibodies were generated in any of the patients throughout the study. To conclude, this study reaffirms the lack of oats immunogenicity and toxicity to coeliac patients. It also suggests that the antigenic stimulus caused by wheat exposure differs fundamentally from that caused by oats.

    Background We describe the case of a young woman with seasonal allergic rhinitis who presented with signs of a lower respiratory tract infection, acute renal impairment and the nephrotic syndrome, demonstrated on biopsy to be due to minimal change disease (MCD) with acute tubular injury. Following initiation of high-dose corticosteroids, her respiratory symptoms and renal impairment improved, and the nephrotic syndrome went rapidly into remission, but relapsed, off treatment, in a seasonal fashion. Management In view of significant side effects related to corticosteroids, relapses were treated with the calcineurin inhibitor tacrolimus with excellent effect, but the patient was keen to avoid the complications of medium-term immunosuppression and so the drug was weaned early. She relapsed for the second time, whilst off tacrolimus, at the same time of year as at her initial presentation. In subsequent years we have successfully managed this patient with seasonal relapsing MCD with seasonal prophylactic tacrolimus therapy. Discussion We discuss the natural history of MCD and treatment options and demonstrate the utility of a clear understanding of the natural history of the condition in order to predict disease relapse and tailor therapy to the individual patient.

    High levels of arsenic exposure have been associated with increases in cardiovascular disease risk. However, studies of arsenic's effects at lower exposure levels are limited and few prospective studies exist in the United States using long-term arsenic exposure biomarkers. We conducted a prospective analysis of the association between toenail arsenic and cardiovascular disease mortality using longitudinal data collected on 3939 participants in the New Hampshire Skin Cancer Study. Using Cox proportional hazard models adjusted for potential confounders, we estimated hazard ratios and 95% confidence intervals associated with the risk of death from any cardiovascular disease, ischemic heart disease, and stroke, in relation to natural-log transformed toenail arsenic concentrations. In this US population, although we observed no overall association, arsenic exposure measured from toenail clipping samples was related to an increased risk of ischemic heart disease mortality among long-term smokers (as reported at baseline), with increased hazard ratios among individuals with ≥ 31 total smoking years (HR: 1.52, 95% CI: 1.02, 2.27), ≥ 30 pack-years (HR: 1.66, 95% CI: 1.12, 2.45), and among current smokers (HR: 1.69, 95% CI: 1.04, 2.75). These results are consistent with evidence from more highly exposed populations suggesting a synergistic relationship between arsenic exposure and smoking on health outcomes and support a role for lower-level arsenic exposure in ischemic heart disease mortality.

    Background: We herein report the long-term results of an allogeneic reduced-intensity conditioning (allo-RIC) protocol used in 21 consecutive patients (16 males, median age 56 years, 71% in complete remission) diagnosed with mantle cell lymphoma (MCL). Methods: The allo-RIC consisted of fludarabine plus melphalan and peripheral blood hematopoietic stem cells (PBSCs) from human leukocyte antigen (HLA)-identical siblings were used in all cases. Median CD34+ infused cells was 5.8 times 106/kg. All patients engrafted promptly. Results: Early toxicity included mild/moderate mucositis (43%), febrile neutropenia (33%) and bacterial infections (19%). With a median follow up of 48 months, four deaths were reported, all due to infections and/or graft-versus-host disease (GVHD), yielding a 3-year cumulative incidence of nonrelapse mortality of 19.5%. Grade III—IV acute GVHD occurred in 15% and chronic GVHD in 78%, being extensive in 39%. The 5-year progression-free survival (PFS) and overall survival (OS) were both 80% (95% CI: 63-97%). Age was the only possible prognostic factor for OS, which was 43% for those aged more than 60 years and 100% for those younger (p < 0.001). Conclusions: Our data confirm that allo-RIC offers a low toxicity profile and a chance for prolonged long-term disease-free survival in MCL, particularly in younger patients. PMID:23556071

    Purpose: Ischemic heart disease (IHD) may result in lethal conditions such as ischemic cardiomyopathy (ICM) and mitral regurgitation (MR). Methods: We hypothesized preoperative LV volume would be highly associated with long-term survival in such patients. We retrospectively evaluated effects of LV end-systolic volume index (LVESVI) on survival. Results: Patients were divided into two groups according to LVESVI; Group S (n = 19, <100 ml/m2), and L (n = 55, >100 ml/m2). There were 74 patients (male 61, female 13; 61 ± 10 y.o.). There was no statistical significance in preoperative parameters, including ejection fraction (EF), severity of MR, severity of tricuspid regurgitation (TR), and right ventricular systolic pressure (RVSP). After operation, LVESVI and severity of MR were statistically reduced in both groups. However, EF, severity of TR and RVSP were not statistically alleviated in both groups. In Group S, 5- and 10-year survival rates were 93% and 48%. In Group L, 5- and 10-year survival rates were 50% and 29%. There was a statistical difference in long-term survival between two groups. Conclusions: Preoperative LV volume would be one of the risk factors for long-term survival in patients with congestive heart failure secondary to IHD. Careful follow-up and optimal treatment should be recommended before LV dimension becomes too large. PMID:26073141

    An asymptomatic 74-year-old woman, on follow-up for a carotid body tumor, showed magnetic resonance imaging (MRI) focal restricted diffusion confined to the left temporal and occipital cortices. Thirteen months later, diffusion-weighted images revealed a bilateral cortical ribbon sign involving all lobes. After 1 month, the patient developed gait instability and cognitive decline rapidly evolving to severe dementia and death within 3 months. Prion protein gene sequence, molecular, and neuropathological studies confirmed the diagnosis of sporadic Creutzfeldt-Jakob disease (sCJD) MM1 subtype. Here we show the kinetics of MRI changes and prion spreading in preclinical sCJD MM1. Ann Neurol 2016;80:629-632. PMID:27501375

    The study examined Hypothalamus-Pituitary-Adrenal (HPA) axis and inflammatory signaling in 206 youth with histories of prenatal drug exposure and self-reported histories of maltreatment. Youth with histories of severe neglect showed elevated levels of cortisol, the end product of the HPA axis, in comparison to youth with lower or minimal levels of neglect. Histories of severe neglect also were associated with increased levels of Macrophage Migration Inhibitory Factor (MIF), a cytokine known to be intricately involved in HPA axis regulation. Salivary MIF levels also were positively associated with youth age and prenatal drug exposure. These MIF and cortisol alterations may signal pathophysiological disruptions in the neuro-endocrine and immune systems, which may lead to trajectories of increased disease risk among vulnerable youth. Our findings also provide preliminary support for the validity and reliability of a noninvasive salivary assessment of MIF.

    Uterine leiomyosarcoma (ULMS) is an aggressive tumor associated with high rates of progression, recurrence, and mortality. Pazopanib is the only approved molecular targeted drug for advanced soft tissue sarcoma, and it has been proven to prolong progression-free survival relative to placebo. We herein report a case of ULMS with multiple lung metastases treated with pazopanib, which led to sustained disease control for 44 weeks. A 53-year-old woman was referred to our hospital due to massive uterine bleeding from a uterine corpus tumor mass. Total abdominal hysterectomy with bilateral salpingo-oophorectomy was performed as emergency surgery. The final histopathological diagnosis was uterine leiomyosarcoma, and computed tomography revealed multiple lung metastases. After chemotherapy with 17 cycles of gemcitabine and docetaxel and two cycles of doxorubicin, the lung metastases had increased in size and new lesions had appeared. Pazopanib administration at 800 mg/day was started as third-line therapy. Ten weeks later, the dose of pazopanib was reduced to 600 mg/day because of hepatic impairment and hypertension. However, lung metastases of ULMS were stabilized by pazopanib administration for about 44 weeks without a decline in the patient's quality of life. After 44 weeks of therapy, pazopanib administration was discontinued because of progressive disease and worsening of the patient's respiratory status. Pazopanib is an oral multityrosine kinase inhibitor of vascular endothelial growth factor receptor-1, -2, and -3; platelet-derived growth factor-α and -β; and c-Kit receptor. The role of pazopanib may be clinically significant in the treatment of advanced ULMS. PMID:27578036

    The first 86 patients with Cushing's disease treated with interstitial irradiation (by needle implantation) as the sole therapy were reviewed. In the 82 patients who were reassessed 1 yr after treatment 63 (77%) achieved remission. This study comprises the outcome and complications in the 54 patients who had a remission and whom we were able to follow. The follow-up period ranged from 3-26 yr (mean, 10.5) from the time of remission. No instance of clinical or radiological relapse has occurred. Of these 54 patients, yttrium-90 alone was used in 32, of whom 12 (37%) required corticosteroid or T4 replacement therapy in a mean time of 3.5 months; in 7 of these 12 we elected to give an ablative dose. Gold-198 alone was used in 15 patients, of whom 7 (47%) developed hypopituitarism in a mean time of 76 months. Both isotopes were used in 7 patients. A diurnal serum cortisol rhythm was found in 28 of the 31 patients who were not receiving corticosteroid therapy. In 5 of the 7 patients with an initially abnormal pituitary fossa, serial radiological studies revealed remodelling in 3. There have been no complications in the last 17 years. Pituitary implantation with yttrium-90 is an effective alternative to transsphenoidal hypophysectomy, with a high remission rate, no recurrence (as yet), no operative complications, and avoidance of hormone replacement in the majority.

    The Nottinghamshire Lymphoma Registry contains the details of all patients diagnosed with lymphoma (since 1 January 1973) within a defined geographical area with a stable population of 1.1 million. The aim of this study was to investigate the relative survival and estimate the cure fraction for patients with Hodgkin disease (HD) using various cure fraction models. Five- and 10-year survival was estimated in comparison to the general population of the same age, gender and year of diagnosis. Relative survival probabilities at 10 years were 52.3% for the 1973-1982 cohort, 67.8% (1983-1992) and 75.7% (1993-2002). The estimated cured fraction (π) was 45%, 65% and 75%, respectively, for the same cohorts. There was very little excess mortality after 4 years from treatment. The prognosis of patients with HD has improved progressively within a defined unselected population over this 30-year period. In the 1993-2002 cohort the prognosis after 4 years of treatment is almost the same as for a normal population.

  6. Evolutionary decay and the prospects for long-term disease intervention using engineered insect vectors

    PubMed Central

    2015-01-01

    After a long history of applying the sterile insect technique to suppress populations of disease vectors and agricultural pests, there is growing interest in using genetic engineering both to improve old methods and to enable new methods. The two goals of interventions are to suppress populations, possibly eradicating a species altogether, or to abolish the vector’s competence to transmit a parasite. New methods enabled by genetic engineering include the use of selfish genes toward either goal as well as a variety of killer-rescue systems that could be used for vector competence reduction. This article reviews old and new methods with an emphasis on the potential for evolution of resistance to these strategies. Established methods of population suppression did not obviously face a problem from resistance evolution, but newer technologies might. Resistance to these newer interventions will often be mechanism-specific, and while it is too early to know where resistance evolution will become a problem, it is at least possible to propose properties of interventions that will be more or less effective in blocking resistance evolution.

    Objective To evaluate whether the good and excellent functional results from arthroscopic repair of massive rotator cuff tears are maintained over the long term. Methods From the sample of the study conducted by our group in 2006, in which we evaluated the functional results from arthroscopic repair of massive rotator cuff tears, 35 patients were reassessed, 8 years after the first evaluation. The inclusion criteria were that these patients with massive rotator cuff tears operated by means of an arthroscopic technique, who participated in the previous study and achieved good or excellent outcomes according to the UCLA criteria. Patients whose results were not good or excellent in the first evaluation according to the UCLA criteria were excluded. Results Among the 35 patients reassessed, 91% of them continued to present good and excellent results (40% excellent and 51% good), while 3% presented fair results and 6% poor results. The time interval between the first and second evaluations was 8 years and the minimum length of follow-up since the immediate postoperative period was 9 years (range: 9–17 years), with an average of 11.4 years. Conclusion The good and excellent results from arthroscopic repair of massive rotator cuff tears were mostly maintained (91%), with the same level of function and satisfaction, even though 8 years had passed since the first assessment, with a follow-up period averaging 11.4 years.

    Ketoconazole is listed among drugs that prolong QT interval and may increase the risk of torsade de pointes, a severe ventricular arrhythmia. This compound has recently been approved for treatment of Cushing's syndrome, a severe endocrine disorder. These patients harbour several risk factors for prolonged QT interval, for example hypokalaemia and left ventricular hypertrophy, but no study has evaluated whether administration of ketoconazole affects their QT interval. The aim of this study was to assess the QT interval in patients with Cushing's disease during long-term administration of ketoconazole. Electrocardiograms from 15 patients with Cushing's disease (12 women, 3 men, age: 37.8 ± 2.66 years) on ketoconazole treatment (100 mg-800 mg qd) for 1 month to 12 years were reviewed retrospectively. QT interval was measured and corrected for heart rate (QTc). Measurements before and during ketoconazole treatment were compared and any abnormal QTc value recorded. Concurrent medical therapies were also documented. On average, QTc was superimposable before and during ketoconazole treatment (393.2 ± 7.17 versus 403.3 ± 6.05 msec. in women; 424.3 ± 23.54 versus 398.0 ± 14.93 msec. in men, N.S.). QTc normalized on ketoconazole in one man with prolonged QTc prior to treatment; no abnormal QTc was observed in any other patient during the entire observation period, even during concurrent treatment with other QT-prolonging drugs. In conclusion, long-term ketoconazole administration does not appear to be associated with significant prolongation of QT interval in patients with Cushing's disease. ECG monitoring can follow recommendations drawn for other low-risk QT-prolonging drugs with attention to specific risk factors, for example hypokalaemia and drug interactions.

    The Mizunami Underground Research Laboratory (MIU) is now under construction by the Japan Atomic Energy Agency in the Cretaceous Toki granite in the Tono area of central Japan. Conceptual design of the MIU consists of two 1,000 m shafts (the Main Shaft and the Ventilation Shaft) and horizontal research galleries. The MIU project is a broad scientific study of the deep geological environment as a base for the research and development for geological disposal of nuclear wastes. One of the main goals is to establish comprehensive techniques for investigation, analysis and assessment of the deep geological environment in fractured crystalline rock. The project is being implemented in three overlapping phases: Surface-based Investigation (Phase I), Construction (Phase II) and Operation (Phase III), with a total duration of 20 years. In Phase I, surface investigations were carried out in a stepwise manner in order to obtain information of the geological environment at the site scale (about 2km square). Geological modeling and simulations of various kinds had been carried out in order to synthesize these investigation results. Two NNW-trending faults, which are important for hydrogeological characterization, are included in the model. One of the faults (fault A) strikes through the site in the immediate vicinity of the Main Shaft and another fault (fault B) strikes through the southern part of the MIU construction site. In Phase II, field investigations have been carried out in and around the MIU construction site. For hydrogeological characterization, long term monitoring of hydraulic pressure, surface tilt and self-potential have been carried out on surface and in the research galleries to obtain information on changes of groundwater flow due to shaft excavation. The results of the long term monitoring focused on fault A are as follows: - The hydraulic pressure responses are observed in surface boreholes in and around the MIU construction site and the galleries.

    The study was aimed at elucidating the prevalence and long-term trends of chronic non-infectious diseases among students of Kabardino-Balkarian Republic in the period of socio-economic changes for the elaboration and implementation of scientifically sound recommendations for the improvement of their health status. Four population studies were simultaneously conducted between 1999 and 2001 including 1542 subjects (613 men and 929 women) at risk of chronic non-infectious diseases with the low level of physical activity (76.3%), high personal and reactive anxiety level (41.8 and 28.9%), smoking (15.5%), overweight (10.5%), and arterial hypertension (5.7%). A combination of several risk factors of chronic non-infectious diseases was documented in 32.8% of the students. The prevalence of AH, low physical activity, high personal and reactive anxiety decreased in 2005 compared with 1999 but increased again by 2011. The number of smokers and students with a single risk factor of chronic non-infectious diseases decreased while the number of students with several risk factors increased (p<0. 05-0.0001). High frequency of risk factors of chronic non-infectious diseases suggests the necessity of development and realization of regional prophylactic programs.

    The "Komplast" materials experiment was designed by the Khrunichev State Research and Production Space Center together with Skobeltsyn Institute of Nuclear Physics, Lomonosov Moscow State University and other Russian scientific institutes, and has been carried out since 1998. The aim of the experiment is to study the complex effects of space factors on specimens of various materials. Eight “Komplast” panels fitted with material specimens equipped UV-sensors and temperature sensors were located on the International Space Station (ISS) Functional Cargo Block (FGB) module exterior surface. The panels were sent into orbit with the FGB when it launched on November 20, 1998. Two of these panels were subsequently returned to Earth by Space Shuttle Discovery after 12 years of LEO exposure. The uniqueness of the "Komplast" experiment determined by long duration of open space exposure, which is much longer than in other similar experiments. For example LDEF: 1984-1990, МЕЕР (Space Station «Mir»): 1996-1997, MISSE-1, -2 (ISS): 1,5-2 years. In this work reveals laboratory research results of some materials specimens, which had been exposed on “Komplast” panels. A distinctive feature of this research was additional irradiation of specimens by atomic oxygen and electrons with energies of ~ 1-8 MeV in laboratory. In the interpretation of the experiment results was taken into account the specimens exposure temperature conditions on the ISS exterior surface and the conditions of their sunlit, defined by the above-mentioned sensors readings. Lot of attention was paid to the investigation of rubber materials specimens. The deformation, mechanical and relaxation characteristics were defined for the specimens. Also were investigations the seals-ability of model rubber seals after the long-term outer exposure. It was determined conservation volumetric deformation and relaxation characteristics of the exposed specimens and the localization of structural changes in the thin

    Background and Aims To evaluate the National Immunisation Programme (NIP) a population-based cross-sectional seroepidemiological study was performed in the Netherlands. We assessed diphtheria antitoxin levels in the general Dutch population and in low vaccination coverage (LVC) areas where a relatively high proportion of orthodox Protestants live who decline vaccination based on religious grounds. Results were compared with a nationwide seroepidemiological study performed 11 years earlier. Methods In 2006/2007 a national serum bank was established. Blood samples were tested for diphtheria antitoxin IgG concentrations using a multiplex immunoassay for 6383 participants from the national sample (NS) and 1518 participants from LVC municipalities. A cut-off above 0.01 international units per ml (IU/ml) was used as minimum protective level. Results In the NS 91% of the population had antibody levels above 0.01 IU/ml compared to 88% in the 1995/1996 serosurvey (p<0.05). On average, 82% (vs. 78% in the 1995/1996 serosurvey, p<0.05) of individuals from the NS born before introduction of diphtheria vaccination in the NIP and 46% (vs. 37% in the 1995/1996 serosurvey, p = 0.11) of orthodox Protestants living in LVC areas had antibody levels above 0.01 IU/ml. Linear regression analysis among fully immunized individuals (six vaccinations) without evidence of revaccination indicated a continuous decline in antibodies in both serosurveys, but geometric mean antibodies remained well above 0.01 IU/ml in all age groups. Conclusions The NIP provides long-term protection against diphtheria, although antibody levels decline after vaccination. As a result of natural waning immunity, a substantial proportion of individuals born before introduction of diphtheria vaccination in the NIP lack adequate levels of diphtheria antibodies. Susceptibility due to lack of vaccination is highest among strictly orthodox Protestants. The potential risk of spread of diphtheria within the geographically

    Liver inflammation as a response to injury is a highly dynamic process involving the infiltration of distinct subtypes of leukocytes including monocytes, neutrophils, T cell subsets, B cells, natural killer (NK) and NKT cells. Intravital microscopy of the liver for monitoring immune cell migration is particularly challenging due to the high requirements regarding sample preparation and fixation, optical resolution and long-term animal survival. Yet, the dynamics of inflammatory processes as well as cellular interaction studies could provide critical information to better understand the initiation, progression and regression of inflammatory liver disease. Therefore, a highly sensitive and reliable method was established to study migration and cell-cell-interactions of different immune cells in mouse liver over long periods (about 6 hr) by intravital two-photon laser scanning microscopy (TPLSM) in combination with intensive care monitoring. The method provided includes a gentle preparation and stable fixation of the liver with minimal perturbation of the organ; long term intravital imaging using multicolor multiphoton microscopy with virtually no photobleaching or phototoxic effects over a time period of up to 6 hr, allowing tracking of specific leukocyte subsets; and stable imaging conditions due to extensive monitoring of mouse vital parameters and stabilization of circulation, temperature and gas exchange. To investigate lymphocyte migration upon liver inflammation CXCR6.gfp knock-in mice were subjected to intravital liver imaging under baseline conditions and after acute and chronic liver damage induced by intraperitoneal injection(s) of carbon tetrachloride (CCl4). CXCR6 is a chemokine receptor expressed on lymphocytes, mainly on Natural Killer T (NKT)-, Natural Killer (NK)- and subsets of T lymphocytes such as CD4 T cells but also mucosal associated invariant (MAIT) T cells1. Following the migratory pattern and positioning of CXCR6.gfp+ immune cells allowed a

    Damage of intact rock is commonly driven by the interaction of long-term low-magnitude external environmental stresses in combination with surface chemistry, rather than short-term loading in excess of intact rock strength. In order to determine the contribution of environmental stresses to the propagation of micro- and macroscopic fractures under natural environmental conditions we undertook long-term three-point bending tests on large size Carrara Marble specimens. The interaction of mechanical stresses induced by external loading and corrosive conditions (e.g. the presence of water) at the tip of a pre-existing crack is termed stress corrosion. We investigate stress corrosion below saw cut notches in wet and dry samples of Carrara Marble (M1-5, each 10cm x 10cm x 110cm). These were pre-loaded to about 66% of their assumed ultimate strength (determined by the fracture toughness (Kic) calculated for the crack tip). Two marble beams (M1, M3) were initially loaded to 22% and three (M2, M4, M5) to 55% of Kic. CaC03 saturated water was continuously dripped in the notch of samples --M1-4 to create corrosive conditions, while M5 was kept dry. After a three-week bedding period, loading on sample M1 was increased to 55%, M2 and M5 to 77% and M3 and M4 to 85% of Kic respectively. The tests were interrupted prior to failure of the specimens in order to allow the assessment of the crack-tip structure. During the testing period we used classical strain gages and acoustic emission sensors to measure strain and elastic stress changes through coda wave interferometry. Temperature and humidity were monitored and the outflowing fluid was collected for future analysis, throughout. The effect of induced damage on residual intrinsic stresses was evaluated using neutron diffraction on the SALSA instrument at the Institute Laue-Langevin (ILL, Grenoble, France), while texture measurements were undertaken using the X-ray goniometer at the Geoscience Center, University Göttingen, and

    Aspartame (APM) is one of the most widely used artificial sweeteners in the world. Its ever-growing use in more than 6000 products, such as soft drinks, chewing gum, candy, desserts, etc., has been accompanied by rising consumer concerns regarding its safety, in particular its potential long-term carcinogenic effects. In light of the inadequacy of the carcinogenicity bioassays performed in the 1970s and 1980s, a long-term mega-experiment on APM was undertaken at the Cesare Maltoni Cancer Research Center of the European Ramazzini Foundation on groups of male and female Sprague-Dawley rats (100-150/sex/group), 8 weeks old at the start of the experiment. APM was administered in feed at concentrations of 100,000, 50,000, 10,000, 2,000, 400, 80, or 0 ppm. Treatment lasted until spontaneous death of the animals. The results of the study demonstrate that APM causes: (a) an increased incidence of malignant tumor-bearing animals, with a positive significant trend in both sexes, and in particular in females treated at 50,000 ppm (P < or = 0.01) when compared to controls; (b) an increase in lymphomas-leukemias, with a positive significant trend in both sexes, and in particular in females treated at doses of 100,000 (P < or = 0.01), 50,000 (P < or = 0.01), 10,000 (P < or = 0.05), 2000 (P < or = 0.05), and 400 ppm (P < or = 0.01); (c) a statistically significant increased incidence, with a positive significant trend, of transitional cell carcinomas of the renal pelvis and ureter in females and particularly in those treated at 100,000 ppm (P < or = 0.05); and (d) an increased incidence of malignant schwannomas of the peripheral nerves, with a positive trend in males (P < or = 0.05). The results of this mega-experiment indicate that APM, in the tested experimental conditions, is a multipotential carcinogenic agent.

    Objectives: Our aim was to present mid-long term functional outcomes of patients who underwent arthroscopic selective capsular release and manipulation for frozen shoulder refractory to conservative treatment. Methods: Between 2006 and 2012, 32 patients presented to our clinic with the diagnosis of frozen shoulder. 24 shoulders of 22 patients treated with arthroscopic selective capsular release and manipulation were included in the study. Functional results were analyzed with Constant shoulder score. The mean follow-up was 4.3 years (range 1-7 years). Results: We detected an average increase in passive range of motion in flexion 72°, abduction 90°, abduction-internal rotation 33°, and abduction-external rotation 38°, adduction-external rotation at 37° compared to the preoperative status. Constant shoulder score increased by an average of 44 points after surgery. Eighteen (82%) patients were satisfied with the operation. Three of four patients whose symptoms persisted had resistant diabetes mellitus. Conclusion: Frozen shoulder is one of the most well-known causes of shoulder pain and disability. Although surgery has a good rate of success it does not help in all cases. Unsatisfactory results may be experienced in patients who have diabetes mellitus as a confounding factor.

    In a prospective clinical trial, 26 consecutive patients underwent endoscopic pneumatic dilatation over a 10-year period. Dilatation was achieved by means of a balloon attached to a normal gastrointestinal fiberscope. With the endoscope in an inverse position, the device was placed in the cardia and the dilatation process was monitored macroscopically. Before dilatation, patients suffered from dysphagia (92%), reduced speed of swallowing (100%), symptom aggravation under stress (73%), weight loss (50%), aspiration, pain, regurgitation, and vomiting. After dilatation and long-term follow-up (mean of 5 years), symptoms could be markedly reduced, especially the speed of eating and symptom aggravation under stress. Excellent and good results (Visick scale) were achieved in 76%. Fair results were achieved in 20%. To date, perforation and other complications have not occurred. Mortality was zero. Our series was an uncontrolled trial, so the results are hardly comparable to other studies. Furthermore, the small number of patients in our study represents a weak point with regard to complications. We conclude that the main advantages of the procedure are its simplicity and practicability. The simple procedure may be the method of choice in elderly patients. Of course, no final decision can be made until a well-designed controlled trial has been carried out.

    Objectives: In most patients with aortic regurgitation (AR), aortic valve replacement (AVR) improves left ventricular (LV) function, but some patients will not have favorable remodeling. Our objectives were to review long term clinical results of AVR for AR and to examine what factors affect the normalization of LV function after AVR for chronic AR. Methods: Between 1989 and 2010, 177 patients underwent isolated AVR for chronic pure AR. The patients were divided into 2 groups based on indexed end-systolic LV diameter (iESD): Group L (iESD) ≧25 mm/m2) (130 patients) and Group S (iESD <25 mm/m2) (47 patients). Results: There was no significant difference between groups in late mortality, freedom from cardiac-related death and rehospitalization for heart failure at late follow up after operation. At postoperative follow-up, 16% of patients had not recovered normal LV systolic function. By means of multivariate analysis, iESD and cardiac index (CI) were independent predictors of recovery of LV function and iESD >26.7 mm/m2 and CI <2.71 l/min/m2 were the best cut-off values. Conclusions: Early and late surgical results of AVR for chronic AR were good, but for the preservation of postoperative normal LV function, AVR for AR patients should be performed before iESD reaches 26.7 mm/m2.

    The RACF (RHIC-ATLAS Computing Facility) has operated a large, multi-purpose dedicated computing facility since the mid-1990’s, serving a worldwide, geographically diverse scientific community that is a major contributor to various HEPN projects. A central component of the RACF is the Linux-based worker node cluster that is used for both computing and data storage purposes. It currently has nearly 50,000 computing cores and over 23 PB of storage capacity distributed over 12,000+ (non-SSD) disk drives. The majority of the 12,000+ disk drives provide a cost-effective solution for dCache/XRootD-managed storage, and a key concern is the reliability of this solution over the lifetime of the hardware, particularly as the number of disk drives and the storage capacity of individual drives grow. We report initial results of a long-term study to measure lifetime PB read/written to disk drives in the worker node cluster. We discuss the historical disk drive mortality rate, disk drive manufacturers' published MPTF (Mean PB to Failure) data and how they are correlated to our results. The results help the RACF understand the productivity and reliability of its storage solutions and have implications for other highly-available storage systems (NFS, GPFS, CVMFS, etc) with large I/O requirements.

    Amazon basin during the wet season is one of the few places on Earth where "natural atmosphere", as it is expected to be in pre-industrial era, can be observed. Atmosphere in clean Amazonia can be regarded as a baseline state of tropical atmosphere. Its hydrological cycle is extreme active, as well as its convection. Several scientific questions with respect to convection remain unclear. Diurnal cycle of convection is far from adequately represented in numeric models. Precipitation typically occurs in models in the first few hours in the morning, whereas actual rain occurs mostly in the early afternoon. Convection parameterizations lack the ability to represent it adequately due to the models coarse resolution of parameterizations compared to the spatial scale of shallow convection. An adequate comprehension of shallow to deep convection transition is critical to improve convection representation in models. To reach this goal, long term measurements that could characterize clouds and convection diurnal cycle are fundamental. The implementation of ACONVEX (Atmospheric CONVection EXperiment) site, situated 50 km upwind from the megacity of Manaus ( -2.894263S°, -59.971452W) aims to fill the existent gap in long term measurements. It is designed to make measurements for more than 10 yrs, and characterize cloud properties in a climatological perspective. The site started its operation in August, 2011, initially with the Raman Lidar. Present time instrumentation set comprises: 1) UV Lidar Raman, 2) CIMEL Sunphotometer, 3) MultiFilter shadow band Radiometer (MFR), 4) GNSS/GPS Receiver, 5) Vertical Pointing Radar, 6) Disdrometer, 7) Ceilometer, 8) Met station. Two sky imagers and a microwave radiometer are about to be operated and will be able to derive 1) Cloud Cover, 2) Cloud Top and Cloud Base Heights, 3) Liquid Water Content, 4) Integrated Precipitable Water, 5) PBL Height, 6) Rain Rate (vertical profile and at surface).

    AMMA-CATCH is a multi-scale observation system dedicated to long-term monitoring of the water cycle, the vegetation dynamics and their interaction with climate and water resources in West Africa. In the context of the global change, long-term observations are required to i) gain understanding in eco-hydrological processes over this highly contrasted region, ii) help their representation in Earth System Models, and iii) detect trends and infer their impacts on water resources and living conditions. It is made of three meso-scale sites (~ 1°x1°) in Mali, Niger and Benin, extending along the West African eco-climatic gradient. Within this regional window (5° by 9°), each of the three sites comprises a multi-scale set-up which helps documenting the components of the hydrologic budget and the evolutions of the surface conditions over a range of time scales: raingages, piezometers, river discharge stations, soil moisture and temperature profiles, turbulent fluxes measurements, LAI/biomass monitoring. This observation system has been continuously generating coherent datasets for 10 to 25 years depending on the datasets. It is jointly operated by French and African (Mali, Niger and Benin) research institutions. The data-base is available to the community through the website (www.amma-catch.org). AMMA-CATCH is a member of the French critical zone observatory network "Réseau des Bassins Versants", (RBV). AMMA-CATH participates to several global or regional observation networks, such as FluxNet, CarboAfrica, International Soil Moisture Networks (ISMN) and to calibration/validation campaigns for satellite missions such as SMOS (CNES, ESA), MEGHA-TROPIQUES (France/India) or SWAP(NASA). AMMA-CATCH fills a gap over a region, West Africa, where environmental data are largely lacking, and thus, it can usefully contribute to the international networking effort for environmental monitoring and research.

    This study explored how young adult people living with chronic inflammatory bowel disease (IBD) experienced that knowledge about their body symptoms and their food intake could promote recovery from their diagnosed disease. A hermeneutic approach was used to analyze interviews with patients living with IBD outside hospital. Thirteen young adults 18 to 45 years of age, with IBD, resided in their home environment and were engaged in different study and work activities. Two main themes emerged from the analysis of the interviews: (1) confidence with symptoms of disease as a source to recovery and (2) nutritional recovery in different stages of IBD. The course of the disease may be turned toward regeneration using a balanced diet in a long-term management perspective. Development of a tailored diet will provide energy and act as a catalyst to enhance the adaptive immune system in the body. Embodied knowledge and recovery from IBD within the individual patient requires understanding, clinical support, and the skills of the IBD nurse, dietitian, and doctor in an interdisciplinary team collaboration.

    Increased production and deposition of amyloid β-protein (Aβ) are believed to be key pathogenic events in Alzheimer's disease. As such, routes for lowering cerebral Aβ levels represent potential therapeutic targets for Alzheimer's disease. X11β is a neuronal adaptor protein that binds to the intracellular domain of the amyloid precursor protein (APP). Overexpression of X11β inhibits Aβ production in a number of experimental systems. However, whether these changes to APP processing and Aβ production induced by X11β overexpression also induce beneficial effects to memory and synaptic plasticity are not known. We report here that X11β-mediated reduction in cerebral Aβ is associated with normalization of both cognition and in vivo long-term potentiation in aged APPswe Tg2576 transgenic mice that model the amyloid pathology of Alzheimer's disease. Overexpression of X11β itself has no detectable adverse effects upon mouse behaviour. These findings support the notion that modulation of X11β function represents a therapeutic target for Aβ-mediated neuronal dysfunction in Alzheimer's disease. PMID:19744962

    BACKGROUND & AIMS Use of exogenous hormones, in the form of oral contraceptives (OCs), has been linked consistently to risk of Crohn’s disease (CD). Nonetheless, it is not clear how OCs might contribute to the progression of CD. METHODS We conducted a prospective study of female patients with CD (age, 16–51 y), identified from the inpatient and outpatient care components of the Swedish National Patient Register from January 2002 through December 2013. Information on current OC use was obtained from the Prescribed Drug Register starting in July of 2005 and updated until December of 2013. Primary outcomes were defined as first CD-related surgery and first steroid prescription. We used Cox proportional hazard modeling with time-varying covariates to estimate multivariable-adjusted hazard ratios (MV-adjusted HRs). RESULTS We identified 482 incident cases of surgery among 4036 patients with CD, with a median follow-up period of 58 months. Compared with nonusers, the MV-adjusted HRs for surgery were 1.14 (95% confidence interval [CI], 0.80–1.63) for past users and 1.30 (95% CI, 0.89–1.92) for current users. The risk of surgery increased with longer duration of use (Ptrend = .036) and higher prescribed daily dose (Ptrend = .016). Specifically, for women with more than 3 years of OC use, the MV-adjusted HR for surgery was 1.68 (95% CI, 1.06–2.67). The association was confined to the combination type of OC. We estimated that for every 83 patients with CD receiving the combination type of oral contraceptives for at least 1 year, 1 extra surgery is required. The rate of steroid prescriptions did not appear to increase with past or current use of OCs, compared with patients who have not taken OCs (all Pcomparisons > .20). CONCLUSIONS In a nationwide analysis of patients in Sweden, long-term use of OCs, particularly the combination type, was associated with an increased risk of surgery among women with established CD. Clinicians carefully should evaluate and monitor

    This paper summarizes the problem specification and compares participants results for the OECD/NEA/WPNCS Expert Group on Burn-up Credit Criticality Safety Phase VII Benchmark Study of Spent Fuel Compositions for Long-Term Disposal. The Phase VII benchmark was developed to study the ability of relevant computer codes and associated nuclear data to predict spent fuel isotopic compositions and corresponding keff values in a cask configuration over the time duration relevant to spent nuclear fuel (SNF) disposal. The benchmark was divided into two sets of calculations: (1) decay calculations out to 1,000,000 years for provided pressurized-water-reactor (PWR) UO2 discharged fuel compositions and (2) burnup credit criticality calculations for a representative cask model at selected time steps. Contributions from 15 organizations and companies in 10 countries were submitted to the Phase VII benchmark exercise. This paper provides a description of the Phase VII benchmark and detailed comparisons of the participants isotopic compositions and keff values that were calculated with a diversity of computer codes and nuclear data sets. Differences observed in the calculated time-dependent nuclide densities are attributed to different decay data or code-specific numerical approximations. The variability of the keff results is consistent with the evaluated uncertainty associated with cross-section data.

    The shaping of the nebula is currently one of the outstanding unsolved problems in planetary nebula (PN) research. Several mechanisms have been proposed, most of which require a binary companion. However, direct evidence for a binary companion is lacking in most PNs. We have addressed this problem by obtaining precise radial velocities of seven bright proto-planetary nebulae (PPNs), objects in transition from the asymptotic giant branch to the PN phases of stellar evolution. These have F-G spectral types and have the advantage over PNs of having more and sharper spectral lines, leading to better precision. Our observations were made in two observing intervals, 1991-1995 and 2007-2010, and we have included in our analysis some additional published and unpublished data. Only one of the PPNs, IRAS 22272+5435, shows a long-term variation that might tentatively be attributed to a binary companion, with P > 22 yr, and from this, limiting binary parameters are calculated. Selection effects are also discussed. These results set significant restrictions on the range of possible physical and orbital properties of any binary companions: they have periods greater than 25 yr or masses of brown dwarfs or super-Jupiters. While not ruling out the binary hypothesis, it seems fair to say that these results do not support it.

    The effect of benzalkonium chlorides (BACs), a widely used class of quaternary ammonium disinfectants, on microbial community structure and antimicrobial resistance was investigated using three aerobic microbial communities: BACs-unexposed (DP, fed a mixture of dextrin/peptone), BACs-exposed (DPB, fed a mixture of dextrin/peptone and BACs), and BACs-enriched (B, fed only BACs). Long-term exposure to BACs reduced community diversity and resulted in the enrichment of BAC-resistant species, predominantly Pseudomonas species. Exposure of the two microbial communities to BACs significantly decreased their susceptibility to BACs as well as three clinically relevant antibiotics (penicillin G, tetracycline, ciprofloxacin). Increased resistance to BACs and penicillin G of the two BACs-exposed communities is predominantly attributed to degradation or transformation of these compounds, whereas resistance to tetracycline and ciprofloxacin is largely due to the activity of efflux pumps. Quantification of several key multidrug resistance genes showed a much higher number of copies of these genes in the DPB and B microbial communities compared to the DP community. Collectively, our findings indicate that exposure of a microbial community to BACs results in increased antibiotic resistance, which has important implications for both human and environmental health.

    This report presents the long-term evaluation results from a hot-dry climate project that examines the room-to-room temperature conditions that exist in a high performance envelope, the performance of a simplified air distribution system, and a comparison of modeled energy performance with measured energy use. The project, a prototype house built by K. Hovnanian Homes’ Ontario Group, is located in Lake Elsinore, Riverside County, California, and achieves a 50% level of whole house source energy savings with respect to the Building America (BA) Benchmark Definition 2009 (Hendron and Engebrecht 2010). Temperature measurements in three rooms indicate that the temperature difference between the measured locations and the thermostat were within recommendations 90.3% of the time in heating mode and 99.3% of the time in cooling mode. The air distribution system is operating efficiently with average delivered temperatures adequate to facilitate proper heating and cooling and only minor average temperature differences observed between the system’s plenum and farthest register. Monitored energy use results for the house indicate that it is using less energy than predicted from modeling. A breakdown of energy use according to end use determined little agreement between comparable values.

    The Balloon Analogue Risk Task (BART) is an experimental measure of risk taking that has commonly been employed to measure the risk taking behavior of nonclinical populations. Previous research has indicated that the task measures a unique aspect of behavioral disinhibition, but there has not as yet been focus upon the possible impact of other aspects of cognitive processing on performance. The current study investigated the cognitive factors related to performance of the BART in an alcohol-using sample. Seventeen individuals with long-term alcohol use were matched for age and education to a group of 17 nonusing participants. The results indicated that the alcohol-using group pumped the balloons on the BART to a lesser extent than did the nonusing group across all trials on the task. The results indicate that the alcohol-using group made less "optimal" decisions on the BART most notably due to neuropsychological impairment in the domains of immediate memory and executive functioning.

    This paper describes the convergence of MELCOR Accident Consequence Code System, Version 2 (MACCS2) probabilistic results of offsite consequences for the uncertainty analysis of the State-of-the-Art Reactor Consequence Analyses (SOARCA) unmitigated long-term station blackout scenario at the Peach Bottom Atomic Power Station. The consequence metrics evaluated are individual latent-cancer fatality (LCF) risk and individual early fatality risk. Consequence results are presented as conditional risk (i.e., assuming the accident occurs, risk per event) to individuals of the public as a result of the accident. In order to verify convergence for this uncertainty analysis, as recommended by the Nuclear Regulatory Commission’s Advisory Committee on Reactor Safeguards, a ‘high’ source term from the original population of Monte Carlo runs has been selected to be used for: (1) a study of the distribution of consequence results stemming solely from epistemic uncertainty in the MACCS2 parameters (i.e., separating the effect from the source term uncertainty), and (2) a comparison between Simple Random Sampling (SRS) and Latin Hypercube Sampling (LHS) in order to validate the original results obtained with LHS. Three replicates (each using a different random seed) of size 1,000 each using LHS and another set of three replicates of size 1,000 using SRS are analyzed. The results show that the LCF risk results are well converged with either LHS or SRS sampling. The early fatality risk results are less well converged at radial distances beyond 2 miles, and this is expected due to the sparse data (predominance of “zero” results).

    Bikini Island was contaminated on March 1, 1954 by the Bravo detonation (U.S. nuclear test series, Castle) at Bikini Atoll. About 90% of the estimated dose from nuclear fallout to potential island residents is from cesium-137 ((137)Cs) transferred from soil to plants that are consumed by residents. Thus, radioecology research efforts have been focused on removing (137)Cs from soil and/or reducing its uptake into vegetation. Most effective was addition of potassium (K) to soil that reduces (137)Cs concentration in fruits to 3-5% of pretreatment concentrations. Initial observations indicated this low concentration continued for some time after K was last applied. Long-term studies were designed to evaluate this persistence in more detail because it is very important to provide assurance to returning populations that (137)Cs concentrations in food (and, therefore, radiation dose) will remain low for extended periods, even if K is not applied annually or biennially. Potassium applied at 300, 660, 1260, and 2070 kg ha(-1) lead to a (137)Cs concentration in drinking-coconut meat that is 34, 22, 10, and about 4% of original concentration, respectively. Concentration of (137)Cs remains low 8-10 y after K is last applied. An explanation for this unexpected result is discussed. PMID:16650918

    The records of 54 labrador retrievers with idiopathic epilepsy were reviewed. Exogenous factors played a minor role in the transmission of the epilepsy. Prodromal phase and aura were present in the majority of the dogs with generalised seizures. The ictal phase was characterised by long-lasting automatisms. Approximately half of the dogs had seizures more than once a month: the remainder ranged from one every two months to one every 12 months. The average frequency in dogs with generalized seizures (n = 49) was one every 65 days and in dogs with partial seizures (n = 5) one every 205 days. Long-term follow-up was performed in 46 dogs, 37 of which followed a strict treatment protocol. Possible causes for the large variations in treatment results were analysed. One goal was to identify objective aspects enabling a realistic prognosis prior to treatment. Animals with a high age at onset of seizure (mean, four years) showed an excellent outcome, even if treatment began late. Dogs with low frequency rates and low total numbers of seizures responded well to therapy if treated as early as possible.

    OBJECTIVE: To determine whether raised plasma glucose concentration independently influences outcome after acute stroke or is a stress response reflecting increased stroke severity. DESIGN: Long-term follow up study of patients admitted to an acute stroke unit. SETTING: Western Infirmary, Glasgow. SUBJECTS: 811 patients with acute stroke confirmed by computed tomography. Analysis was restricted to the 750 non-diabetic patients. MAIN OUTCOME MEASURES: Survival time and placement three months after stroke. RESULTS: 645 patients (86%) had ischaemic stroke and 105 patients (14%) haemorrhagic stroke. Cox's proportional hazards modelling with stratification according to Oxfordshire Community Stroke Project categories identified increased age (relative hazard 1.36 per decade; 95% confidence interval 1.21 to 1.53), haemorrhagic stroke (relative hazard 1.67; 1.22 to 2.28), time to resolution of symptoms > 72 hours (relative hazard 2.15; 1.15 to 4.05), and hyperglycaemia (relative hazard 1.87; 1.43 to 2.45) as predictors of mortality. The effect of glucose concentration on survival was greatest in the first month. CONCLUSIONS: Plasma glucose concentration above 8 mmol/l after acute stroke predicts a poor prognosis after correcting for age, stroke severity, and stroke subtype. Raised plasma glucose concentration is therefore unlikely to be solely a stress response and should arguably be treated actively. A randomised trial is warranted. PMID:9158464

    The paucity of data on migratory connections and an incomplete understanding of how mobile organisms use geographically separate areas have been obstacles to understanding coastal dynamics. Research on acoustically tagged striped bass (Morone saxatilis) at the Plum Island Ecosystems (PIE) Long Term Ecological Research site, Massachusetts, documents intriguing patterns of biotic connectivity (i.e., long-distance migration between geographically distinct areas). First, the striped bass tagged at PIE migrated southward along the coast using different routes. Second, these tagged fish exhibited strong fidelity and specificity to PIE. For example, across multiple years, tagged striped bass resided in PIE waters for an average of 1.5-2.5 months per year (means: 51-72 days; range 2-122 days), left this estuary in fall, then returned in subsequent years. Third, this specificity and fidelity connected PIE to other locations. The fish exported nutrients and energy to at least three other coastal locations through biomass added as growth. These results demonstrate that what happens in an individual estuary can affect other estuaries. Striped bass that use tightly connected routes to feed in specific estuaries should have greater across-system impacts than fish that are equally likely to go anywhere. Consequently, variations in when, where, and how fish migrate can alter across-estuary impacts.

    Aim. To evaluate the technical success and patency rates following primary cutting balloon angioplasty for venous stenoses in native dialysis fistulas. Methods. Forty-one patients (26 men, 15 women; age range 26-82 years, average age 59 years) underwent 50 (repeat procedures in 9 patients) primary cutting balloon (PCB) angioplasty procedures in three institutions by three primary operators. The indication was primary stenosis in 21 patients, recurrent lesions in 15, and immature fistulas in 5. A PCB was used alone in 17 cases, but was followed by a larger standard balloon in 33 cases. Follow-up included ultrasound, flow analysis and urea reduction ratio, and ranged from 2 to 30 months (mean 14 months). Results. The technical success rate was 98%. All procedures were relatively painless. Two PCBs burst and 4 leaked, but without causing any morbidity. Nineteen fistulas were still working at last follow-up. Primary patency rates at 6, 12, and 24 months using Kaplan-Meier analysis were 88%, 73%, and 34%, respectively, and the primary assisted patencies were 90%, 75%, and 50%, respectively. Conclusion. PCB angioplasty has high technical success and low complication rates. The long-term patency rates are favorable for PCB angioplasty and compare favorably with other series.

    We conducted this study to investigate the value of primary stent implantation for the endovascular treatment of focal atherosclerotic stenoses of the infrarenal abdominal aorta. The data of 13 patients with a localized complex infrarenal aortic stenosis who underwent primary stenting was retrospectively evaluated. The patients (6 females, 7 males) had a mean age of 57.3 {+-} 9.1 years (mean {+-} SD). In all patients, the aortic diameter was measured on CT sections, and a self-expanding endoprosthesis was primarily implanted followed by dilatation with single or double balloons. In 3 patients, additional distal stenoses were also endovascularly treated. The procedure was technically successful in all patients. No complications occurred except for 2 minor groin hematomas. During the 43 {+-} 23 months (mean {+-} SD) follow-up (range: 12-96 months), all stented aortic segments remained patent. Clinical patency was lost in 4 patients, which was due to atherosclerosis or restenosis distal to the aorta. In view of the excellent early and long-term results, we believe that primary stenting should be considered the first line treatment in properly selected patients with focal atherosclerotic infrarenal stenoses of the abdominal aorta.

    Sleep apnea is very common in patients with chronic heart failure (CHF) and has important implications in terms of morbidity, mortality and clinical management. Home respiratory telemonitoring might constitute a potential low-cost, widely-applicable alternative to traditional polysomnography in the evaluation and long-term monitoring of breathing disorders in these patients. In this paper we briefly describe the technological infrastructure and present preliminary results of the European Community multicountry trial HHH (Home or Hospital in Heart Failure), which is currently testing a novel system for home telemonitoring of cardiorespiratory signals in CHF patients. The recording and transmitting devices are suitable to be self-managed by the patient. We give a detailed report on the prevalence of nocturnal respiratory disorders at the beginning of the one-year follow-up and on their persistency over the following recordings (one per month). These preliminary findings clearly indicate that intermittent home telemonitoring of respiratory signals based on patient's self-management is feasible in CHF patients and the compliance is high. Reported statistics unambiguously confirm the high prevalence of nocturnal breathing disorders in these patients and clearly show that this phenomenon tends to persist over time. PMID:17271142

    Since 1982, four consecutive studies on childhood acute myeloid leukaemia (AML) (namely LAM-82, -87, -87M and -92) have been conducted in Italy by the Associazione Italiana di Ematologia e Oncologia Pediatrica (AIEOP) group. The induction therapy of the first three studies consisted of daunorubicin and cytarabine structured in a 3+7 backbone. In the most recent protocol (LAM92), patients received two induction courses including idarubicin, cytarabine and etoposide. Patients with acute promyelocytic leukaemia (20% of diagnoses) were included in LAM-87 and 87M studies. Postremissional therapy significantly changed over time, with an ever-increasing role given to stem cell transplantation (SCT). The long-term outcome of patients enrolled in the LAM-82, 87 and 87M studies was comparable, whereas that of children treated according to LAM-92 study was significantly better (P<0.005). Either allogeneic or autologous SCT was employed as consolidation therapy in more than 75% of cases enrolled in this latter study. Patients enrolled in the LAM-92 study were stratified in standard and high-risk groups with different outcome (67 vs 47%, respectively, P=0.04). Altogether, the results obtained in these four studies have permitted a progressive refinement of treatment, contributing to the structure of the ongoing LAM-2002 protocol that stratifies patients according to the presence of definite genetic anomalies and response to induction therapy.

    The nitrous oxide emissions of the Viikinmäki wastewater treatment plant were measured in a 12 month online monitoring campaign. The measurements, which were conducted with a continuous gas analyzer, covered all of the unit operations of the advanced wastewater-treatment process. The relation between the nitrous oxide emissions and certain process parameters, such as the wastewater temperature, influent biological oxygen demand, and ammonium nitrogen load, was investigated by applying online data obtained from the process-control system at 1 min intervals. Although seasonal variations in the measured nitrous oxide emissions were remarkable, the measurement data indicated no clear relationship between these emissions and seasonal changes in the wastewater temperature. The diurnal variations of the nitrous oxide emissions did, however, strongly correlate with the alternation of the influent biological oxygen demand and ammonium nitrogen load to the aerated zones of the activated sludge process. Overall, the annual nitrous oxide emissions of 168 g/PE/year and the emission factor of 1.9% of the influent nitrogen load are in the high range of values reported in the literature but in very good agreement with the results of other long-term online monitoring campaigns implemented at full-scale wastewater-treatment plants.

    This paper presents the long-term data of patients that have been treated with an unconventional implant placement protocol to avoid an invasive surgery when edentulism was caused by an impacted tooth. In 2009, the follow-up of this unconven-tional protocol was 2 to 3.5 years; this article documents now the long-term 5- to 8-year follow-up of 3 patients and 5 im-plants. Over this period of time, implant stability was maintained without complications. This unconventional protocol opens intriguing possibilities; however, more patients with long-term follow-up are warranted before endorsing it in routine appli-cation. Nonetheless, it might suggest that there is still room to revisit one of the leading concepts in dental implantology. PMID:25674167

    Background: Dietary guidelines recommend interchanging protein foods (e.g., chicken for red meat), but they may be exchanged for carbohydrate-rich foods varying in quality [glycemic load (GL)]. Whether such exchanges occur and how they influence long-term weight gain are not established. Objective: Our objective was to determine how changes in intake of protein foods, GL, and their interrelationship influence long-term weight gain. Design: We investigated the association between 4-y changes in consumption of protein foods, GL, and their interaction with 4-y weight change over a 16- to 24-y follow-up, adjusted for other lifestyle changes (smoking, physical activity, television watching, sleep duration), body mass index, and all dietary factors simultaneously in 3 prospective US cohorts (Nurses’ Health Study, Nurses’ Health Study II, and Health Professionals Follow-Up Study) comprising 120,784 men and women free of chronic disease or obesity at baseline. Results: Protein foods were not interchanged with each other (intercorrelations typically <|0.05|) but with carbohydrate (negative correlation as low as −0.39). Protein foods had different relations with long-term weight gain, with positive associations for meats, chicken with skin, and regular cheese (per increased serving/d, 0.13–1.17 kg; P = 0.02 to P < 0.001); no association for milk, legumes, peanuts, or eggs (P > 0.40 for each); and relative weight loss for yogurt, peanut butter, walnuts, other nuts, chicken without skin, low-fat cheese, and seafood (−0.14 to −0.71 kg; P = 0.01 to P < 0.001). Increases in GL were independently associated with a 0.42-kg greater weight gain per 50-unit increase (P < 0.001). Significant interactions (P-interaction < 0.05) between changes in protein foods and GL were identified; for example, increased cheese intake was associated with weight gain when GL increased, with weight stability when GL did not change, and with weight loss when exchanged for GL (i.e., decrease

    Currently, the free fibular flap is well accepted as the first choice for mandibular reconstruction. Achieving functional results in pediatric patients requires a different approach than that employed for mature patients. Because the pediatric craniofacial skeleton continues to grow, reconstruction is more challenging, and the long-term results can be different from those of adult patients. In this study, we sought to measure flap growth objectively in our series. Ten pediatric patients who underwent reconstruction with free fibular flaps were retrospectively reviewed. Flap growth was evaluated by comparing the intraoperative photographs with photographs of the control panoramic mandibular radiographs taken using photo-anthropometric techniques. The measurements were converted to proportionality indices (PI), and these indices were compared. Subsequent complications and functional results were also evaluated. The mean patient age was 11.8 years, and the mean follow up was 57.7 months. The mean preoperative PI value was 10.74  ±  2.47. The mean postoperative PI value was 12.52  ±  2.34. The mean difference between the preoperative and postoperative PI values was -1.78 ± 0.53. These photo-anthropometric data clearly illustrated the growth of the fibular flaps (P = 0.001). None of these patients exhibited nonunion of the fractures; however, one patient experienced a delayed union, one had chronic temporomandibular joint pain, and one had chronic temporomandibular joint luxation. In two patients, the inter-incisive measurements were below the third percentile, and two additional patients had grade 2 eating abilities, which can be regarded as poor. All of the patients had symmetric mandibular contours. Free fibular flaps continue to grow in pediatric patients. This flap is a "workhorse" flap in children because it adapts to the craniofacial skeleton via its ability to grow, and this ability results in subsequent good cosmetic and functional results. PMID

    High levels of arsenic exposure have been associated with increases in cardiovascular disease risk. However, studies of arsenic's effects at lower exposure levels are limited and few prospective studies exist in the United States using long-term arsenic exposure biomarkers. We conducted a prospective analysis of the association between toenail arsenic and cardiovascular disease mortality using longitudinal data collected on 3939 participants in the New Hampshire Skin Cancer Study. Using Cox proportional hazard models adjusted for potential confounders, we estimated hazard ratios and 95% confidence intervals associated with the risk of death from any cardiovascular disease, ischemic heart disease, and stroke, in relation to natural-log transformed toenail arsenic concentrations. In this US population, although we observed no overall association, arsenic exposure measured from toenail clipping samples was related to an increased risk of ischemic heart disease mortality among long-term smokers (as reported at baseline), with increased hazard ratios among individuals with ≥ 31 total smoking years (HR: 1.52, 95% CI: 1.02, 2.27), ≥ 30 pack-years (HR: 1.66, 95% CI: 1.12, 2.45), and among current smokers (HR: 1.69, 95% CI: 1.04, 2.75). These results are consistent with evidence from more highly exposed populations suggesting a synergistic relationship between arsenic exposure and smoking on health outcomes and support a role for lower-level arsenic exposure in ischemic heart disease mortality. - Highlights: • Arsenic (As) has been associated with increased cardiovascular disease (CVD) risk. • Little is known about CVD effects at lower levels of As exposure common in the US. • Few have investigated the joint effects of As and smoking on CVD in US adults. • We examine chronic low-level As exposure and smoking in relation to CVD mortality. • Arsenic exposure may increase ischemic heart disease mortality among smokers in US.

    Purpose: To retrospectively review the results of temporary I-125 brachytherapy in 94 children and adolescents with low-grade glioma. Methods and Materials: Treatment was performed in progressive tumors roughly spherical in shape with a diameter of up to 5 cm, including 79 astrocytomas, 5 oligodendrogliomas, 4 oligoastrocytomas, 1 ependymoma, and 5 other tumors. Location was suprasellar/chiasmal in 44, thalamic/basal ganglia in 18, hemispheric in 15, midbrain/pineal region in 13, and lower brainstem in 3. Initially, 8% of patients were free of symptoms, 47% were symptomatic but not disabled, and 30% were slightly, 6% moderately, and 3% severely disabled. Results: 5- and 10-year survival was 97% and 92%. The response to I-125 brachytherapy over the long term was estimated after a median observation period of 38.4 (range, 6.4-171.0) months. At that time, 4 patients were in complete, 27 in partial, and 18 in objective remission; 15 showed stable and 30 progressive tumors. Treatment results did not correlate with age, sex, histology, tumor size, location, or demarcation of the tumor. Secondary treatment became necessary in 36 patients, including 19 who underwent repeated I-125 brachytherapy. At final follow-up, the number of symptom-free patients had risen to 21%. Thirty-eight percent showed symptoms without functional impairment, 19% were slightly and 11% moderately disabled, and only 4% were severely disabled. Conclusions: Response rates similar to those of conventional radiotherapy or chemotherapy can be anticipated with I-125 brachytherapy in tumors of the appropriate size and shape. We believe it to be a useful contribution to the treatment of low-grade gliomas in children.

    Objective Long-term studies regarding the effect of a structured physical exercise programme (SPEP) during haemodialysis (HD) assessing compliance and clinical benefit are scarce. Study design A single-centre clinical trial, non-randomised, investigating 46 patients with HD (63.2±16.3 years, male/female 24/22, dialysis vintage 4.4 years) performing an SPEP over 5 years. The SPEP (twice/week for 60 min during haemodialysis) consisted of a combined resistance (8 muscle groups) and endurance (supine bicycle ergometry) training. Exercise intensity was continuously adjusted to improvements of performance testing. Changes in endurance and resistance capacity, physical functioning and quality of life (QoL) were analysed over 1 year in addition to long-term adherence and economics of the programme over 5 years. Average power per training session, maximal strength tests (maximal exercise repetitions/min), three performance-based tests for physical function, SF36 for QoL were assessed in the beginning and every 6 months thereafter. Results 78% of the patients completed the programme after 1 year and 43% after 5 years. Participants were divided—according to adherence to the programme—into three groups: (1) high adherence group (HA, >80% of 104 training sessions within 12 months), (2) moderate adherence (MA, 60–80%), and 3. Low adherence group (LA, <60%)) with HA and MA evaluated quantitatively. One-year follow-up data revealed significant (p<0.05) improvement for both groups in all measured parameters: exercise capacity (HA: 55%, MA: 45%), strength (HA: >120%, MA: 40–50%), QoL in three scores of SF36 subscales and physical function in the three tests taken between 11% and 31%. Moreover, a quantitative correlation analysis revealed a close association (r=0.8) between large improvement of endurance capacity and weak physical condition (HA). Conclusions The exercise programme described improves physical function significantly and can be integrated

    Sea ice in the Western Antarctic Peninsula (WAP) region is both highly variable and rapidly changing. In the Palmer Station region, the ice season duration has decreased by 92 days since 1978. The sea-ice changes affect ocean stratification and freshwater balance; and in turn impact every component of the polar marine ecosystem. Long-term observations from the WAP shelf region show a pattern of chlorophyll (Chl) variability with three to five years of negative Chl anomalies interrupted by one or two years of positive anomalies. Observations and results from an inverse food-web model show that these low and high Chl regimes differed significantly from each other, with high primary productivity and net community production (NCP) associated with the high Chl years and vice-versa. Gross primary production averaged 40 mmolC m-2 d-1 in the low Chl years and 100 mmolC m-2 d-1 in the high Chl years, with 30-40% going to NCP across regimes. Only the food web in the southern region in high Chl years was dominated by large phytoplankton and krill, whereas in in all other cases, foodwebs were dominated by small phytoplankton and microzooplankton. These contrasts were strongest between the northern, low Chl years and southern, high Chl years, consistent with earlier north to south observations of sea ice and ecosystem change along the WAP. The relative importance of major bulk carbon flows did not differ substantially between high and low Chl years. Both the northern/low Chl and southern/high Chl regimes had roughly equal proportions of NCP, although its composition reflected shifts in dominance by large versus small plankton. These results suggest that food webs dominated by smaller phytoplankton and grazers have pathways that funnel production into NCP, and likely, export.

    We diagnosed 10 Galeazzi-equivalent injuries. We report the radiological and clinical results at the end of growth in adolescents, including the results of ulnar lengthening. This study included 10 Galeazzi-equivalent injuries (seven patients requiring open reduction and three requiring closed reduction for ulnar lesions) seen since 2004. The periosteum was entrapped around the fractured physis in five patients and the extensor carpi ulnaris to the periosteum was interposed in two patients. Among the seven patients, ulnar lengthening was performed in only three patients. Ulnar variances at the time of the lengthening were -6, -6, and -5 mm. Gradual lengthening was performed. Radiologic abnormalities, including the ulnar variances, were investigated at the end of growth. In addition, pain scores, the range of wrist motion, and grip strength were evaluated and compared with nonlengthened ulnas. The mean age of the patients at the final follow-up was 19.7 years, and the mean total follow-up period was 6 years. The final ulnar variances were -5, -5, -3, and 0 mm in four patients with nonlengthened ulnas among the seven patients. Three patients with lengthened ulnas showed final neutral variances. In four nonlengthened ulnas, three ulnas bowed to the radial side and two ulnar heads had an inclined and deformed shape. Joint mismatch of the distal radioulnar joint surface was found in one patient with lengthened and one with nonlengthened ulnas. Three patients with nonlengthened ulnas showed decreased range of wrist motions. Comparison of contralateral grip strength indicated a significant difference between patients with or without lengthened ulnas. Long-term follow-up after Galeazzi-equivalent injuries may be essential to check for premature epiphyseal closure, length discrepancies, or joint incongruency. A procedure for a shortened ulna could be needed; however, the appropriate time and degree of lengthening remain to be investigated.

    Purpose: To retrospectively evaluate survival of patients with brain metastasis from renal cell carcinoma (RCC) after radiosurgery. Patients and Methods: Between 1998 and 2010, 46 patients were treated with radiosurgery, and the total number of lesions was 99. The mean age was 58.9 years (range, 33-78 years). Twenty-six patients (56.5%) had a single brain metastasis. The mean tumor volume was 3.0 cm{sup 3} (range, 0.01-35.1 cm{sup 3}), and the mean marginal dose prescribed was 20.8 Gy (range, 12-25 Gy) at the 50% isodose line. A patient was classified into the good-response group when the sum of the volume of the brain metastases decreased to less than 75% of the original volume at a 1-month follow-up evaluation using MRI. Results: As of December 28, 2010, 39 patients (84.8%) had died, and 7 (15.2%) survived. The overall median survival time was 10.0 {+-} 0.4 months (95% confidence interval, 9.1-10.8). After treatment, local tumor control was achieved in 72 (84.7%) of the 85 tumors assessed using MRI after radiosurgery. The good-response group survived significantly longer than the poor-response group (median survival times of 18.0 and 9.0 months, respectively; p = 0.025). In a multivariate analysis, classification in the good-response group was the only independent prognostic factor for longer survival (p = 0.037; hazard ratio = 0.447; 95% confidence interval, 0.209-0.953). Conclusions: Radiosurgery seems to be an effective treatment modality for patients with brain metastases from RCC. The early significant tumor volume reduction observed after radiosurgery seems to result in long-term survival in RCC patients with brain metastases.

    Background and purpose The purpose of this article is to report on the long-term success rates of Silk flow-diverter (FD) treatment in a multicenter prospective study for the treatment of complex aneurysms. Methods Between May 2008 and January 2011, all consecutive patients featuring complex intracranial aneurysms eligible for FD treatment with the Silk in three neurovascular centers were included. Clinical and imaging data were assessed during hospitalization and follow-up. Results Five patients were initially asymptomatic, 20 patients showed various neurological symptoms. Twenty-eight FDs were implanted in 25 patients treating 28 aneurysms. The immediate procedure-related morbidity was 8% (two of 25), mortality 0%. One procedure-related death was observed during follow-up (in-stent thrombosis). Compared to the immediate result nearly two of three aneurysms improved during follow-up; all angiographically confirmed inflow changes took place within six months after treatment. Final anatomic outcome in 24 aneurysms of 22 patients comprised 14 (59%) with complete occlusion, seven (29%) with a neck remnant, two (8%) with residual filling <50%, none with residual filling >50% and one (4%) unchanged in comparison to its pretreatment status. Postinterventional recanalizations were seen in three of 13 (23%) aneurysms treated with FD alone; none were observed in 15 aneurysms treated with adjunctive coiling. Conclusion Anatomic presentation and location are key for successful FD treatment. The rate of successful occlusion increases during follow-up. Postinterventional monitoring for at least six months is paramount, as anatomic outcome is not reliably predictable and recanalizations may occur in initially completely occluded aneurysms.

    Objective To evaluate the diagnostic accuracy of the use of an ultrasonography (US)-guided vacuum-assisted biopsy for microcalcifications of breast lesions and to evaluate the efficacy of the use of US-guided vacuum-assisted biopsy with long-term follow-up results. Materials and Methods US-guided vacuum-assisted biopsy cases of breast lesions that were performed between 2002 and 2006 for microcalcifications were retrospectively reviewed. A total of 62 breast lesions were identified where further pathological confirmation was obtained or where at least two years of mammography follow-up was obtained. These lesions were divided into the benign and malignant lesions (benign and malignant group) and were divided into underestimated group and not-underestimated lesions (underestimated and not-underestimated group) according to the diagnosis after a vacuum-assisted biopsy. The total number of specimens that contained microcalcifications was analyzed and the total number of microcalcification flecks as depicted on specimen mammography was analyzed to determine if there was any statistical difference between the groups. Results There were no false negative cases after more than two years of follow-up. Twenty-nine lesions were diagnosed as malignant (two invasive carcinomas and 27 carcinoma in situ lesions). Two of the 27 carcinoma in situ lesions were upgraded to invasive cancers after surgery. Among three patients diagnosed with atypical ductal hyperplasia, the diagnosis was upgraded to a ductal carcinoma in situ after surgery in one patient. There was no statistically significant difference in the number of specimens with microcalcifications and the total number of microcalcification flecks between the benign group and malignant group of patients and between the underestimated group and not-underestimated group of patients. Conclusion US-guided vacuum-assisted biopsy can be an effective alternative to stereotactic-guided vacuum-assisted biopsy in cases where

    Lymphatic malformations (LMs) are rare congenital tumors of the lymphatic system often affecting the head and neck area. Because of cosmetic and functional symptoms most patients need to be treated. Traditionally surgical treatment has been considered to be the first-line treatment for LM. However, it is challenging because of the need for complete excision. The risk of poor cosmetic result and damage to surrounding structures is high. Since Ogita presented OK-432 as a treatment for LM in 1987, it has been widely used as the primary treatment. Many papers have been published on this topic but with relatively short follow-up times. We present a material of 36 LMs treated with OK-432 during the period of 1999-2009 and with an average follow-up time of 6 years. Immediate post-treatment results were compared with the late follow-up findings. Primary and late response to therapy was evaluated with an MRI scan by measuring the change in lesion size. At the follow-up visit, all patients were clinically examined and they answered a symptom questionnaire. Later 26/36 patients were also available for a quality of life questionnaire. Primarily 67% demonstrated a complete or marked response. At the follow-up 64% showed a complete or marked response, in 11% the final response was better than the initially observed and only 2 patients had relapsed. The initial response predicted the long-term outcome accurately and the effect of OK-432 sclerotherapy seems to be long lasting. According to the MRI evaluation 80% and subjectively 94% of the patients benefitted from the treatment. Quality of life questionnaire showed high post-treatment satisfaction. We found OK-432 sclerotherapy to be a safe and effective treatment with a long lasting effect in the management of macrocystic LMs.

    Background: In children less than 6 years, the treatment of femoral shaft fracture is often non surgical, using closed reduction and casting. The literature reports many experience about this type of trauma but none of these has a long term followup. We present a retrospective study on a group of femoral diaphyseal fractures treated nonsurgically in children up to 6 years of age, with a minimum of 10 year followup. Materials and Methods: 48 cases (36 males/12 females) with femoral diaphyseal fractures treated between January 1988 and December 1998 were reviewed. Patients with fractures due to obstetrical trauma and pathologic fractures were excluded. The mean age of the patients was 3.3 ± 1.1 years (range 5 months-6 years). Right side was involved in 21 cases (44%), and left side in 27 cases (56%). In 34 cases (71%), closed reduction was performed and hip spica was applied with the hip and knee flexed to 45°. In 8 cases (17%), skeletal traction was applied to perform fracture reduction and the traction pin was embedded in plaster while in the remaining 6 cases (12%), the Delitala pressure apparatus was applied after casting. Results: All fractures healed in our study. There were no complications (infection or vascular nervous issues, axial deviations, consolidation delays, or pseudoarthrosis). In 13 cases (27%), followup examinations showed mean lengthening of 1.3 ± 0.75 (range 0.5-2.5 cm) of the fractured lower limb. All these patients were treated with skin traction before treatment and presented with 2.08 ± 0.28 cm mean initial femoral shortening. In 1 case (2%) with 2.5 cm lengthening, epiphysiodesis of the ipsilateral knee was performed. No patients showed prolonged difficulty with gait disorders. Conclusion: On the basis of our results conservative treatment of femoral shaft fractures in children can be considered less invasive and safe procedure. PMID:24600060

    Purpose: To evaluate the long-term cause-specific survival (CSS), locoregional recurrence-free survival (LRFS), and metastases-free survival (MFS) in elderly breast cancer patients receiving adjuvant normofractionated (NF) or hypofractionated (HF) radiotherapy (RT). Methods and Materials: Between 1995 and 1999, 367 women aged {>=}70 years with nonmetastatic Stage T1 or T2 tumors were treated by breast-conserving surgery and adjuvant RT at the Institut Curie. They underwent wide tumor excision with or without lymph node dissection followed by RT. They received either a NF-RT schedule, which delivered a total dose of 50 Gy (25 fractions, 5 fractions weekly) to the whole breast, followed by a boost to the tumor bed when indicated, or a HF-RT schedule, which delivered a total dose of 32.5 Gy (five fractions of 6.5 Gy, once weekly) with no subsequent boost. The HF-RT schedule was indicated for the more elderly patients. Results: A total of 317 patients were in the NF-RT group, with 50 in the HF-RT group. The median follow-up was 93 months (range, 9-140). The 5- and 7-year CSS, LRFS, and MFS rates were similar in both groups. The 5-year NF-RT and HF-RT rate was 96% and 95% for CSS, 95% and 94% for LRFS, and 94% and 95% for MFS, respectively. The 7-year NF-RT and HF-RT rate was 93% and 87% for CSS, 93% and 91% for LRFS, and 92% and 93% for MFS, respectively. Conclusion: According to the findings from this retrospective study, the HF-RT schedule is an acceptable alternative to NF-RT for elderly patients. However, large-scale prospective randomized trials are needed to confirm these results.

    Background: To assess the long-term clinical results of spot scanning proton therapy (PT) in the treatment of intracranial meningiomas. Patients and Methods: Thirty-nine patients with meningioma (histologically proven 34/39) were treated with PT between July 1997 and January 2010. Thirty-two (82.1%) patients were treated as primary treatment (exclusive PT, n = 8; postoperative PT, n = 24). Mean age was 48.3 {+-} 17.9 years and 32 (82.1%) patients had skull base lesions. For patients undergoing surgery, 24 patients had a diagnosis of World Health Organization (WHO) Grade I and 10 of a WHO Grade II/III meningioma, respectively. The female-to-male ratio was 3.3. The median administered dose was 56.0 Gy (relative biologic effectiveness [RBE]) (range, 52.2-66.6) at 1.8-2.0 Gy (RBE) per fraction. Gross tumor volume (GTV) ranged from 0.76 to 546.5 cm{sup 3} (median, 21.5). Late toxicity was assessed according to Common Terminology Criteria for Adverse Events version 3.0. Mean follow-up time was 62.0 months and all patients were followed for >6 months. Results: Six patients presented with tumor recurrence and 6 patients died during follow-up, of which 4 of tumor progression. Five-year actuarial local control and overall survival rates were 84.8% and 81.8%, respectively, for the entire cohort and 100% for benign histology. Cumulative 5-year Grade {>=}3 late toxicity-free survival was 84.5%. On univariate analysis, LC was negatively influenced by WHO grade (p = 0.001), GTV (p = 0.013), and male gender (p = 0.058). Conclusions: PT is a safe and effective treatment for patients with untreated, recurrent, or incompletely resected intracranial meningiomas. WHO grade and tumor volume was an adverse prognostic factor for local control.

    The long-term effect of Helicobacter pylori eradication on the natural history of duodenal ulcer has been investigated and compared with long-term acid suppression treatment in an endemic community for infection. Seventy-three patients with endoscopically verified H. pylori positive active duodenal ulcer disease were included in this prospective study. Patients were divided into two groups. Group A patients (n = 39) were given an omeprazole-based triple eradication regimen, while group B patients (n = 34) were given omeprazole alone followed by long-term famotidine 20 mg daily as maintenance treatment. A control endoscopy was performed at the third month of treatment. The bacterium was eradicated in 32 (82%) of group A patients. All patients were followed up for two years and an endoscopy performed at the end of each year. H. pylori recurred in 13 patients and the reinfection rate was 44.8% over two years. Duodenal ulcer recurred in seven of these patients at two years (24.1%). There was a close association between H. pylori reinfection and ulcer relapse. Group B patients remained H. pylori positive during the study and the ulcer recurred in five of these patients (6.6%) despite continuous famotidine treatment. There was no statistically significant difference in ulcer relapse rate between the groups. These results suggested that H. pylori eradication is not an absolute solution for duodenal ulcer disease in high endemic regions and continuous maintenance treatment with H2-receptor antagonists is still an alternative approach in some chronic recurrent cases.

    The capture and geological storage of CO 2 can be used to reduce anthropogenic greenhouse gas emissions. To assess the environmental impact of potential CO 2 leakage from deep storage reservoirs on the abundance and functional diversity of microorganisms in near-surface terrestrial environments, a natural CO 2 vent (>90% CO 2 in the soil gas) was studied as an analogue. The microbial communities were investigated using lipid biomarkers combined with compound-specific stable carbon isotope analyses, the determination of microbial activities, and the use of quantitative polymerase chain reactions (Q-PCR). With this complementary set of methods, significant differences between the CO 2-rich vent and a reference site with a normal CO 2 concentration were detected. The δ 13C values of the plant and microbial lipids within the CO 2 vent demonstrate that substantial amounts of geothermal CO 2 were incorporated into the microbial, plant, and soil carbon pools. Moreover, the numbers of Archaea and Bacteria were highest at the reference site and substantially lower at the CO 2 vent. Lipid biomarker analyses, Q-PCR, and the determination of microbial activities showed the presence of CO 2-utilising methanogenic Archaea, Geobacteraceae, and sulphate-reducing Bacteria (SRB) mainly at the CO 2 vent, only minor quantities were found at the reference site. Stable carbon isotopic analyses revealed that the methanogenic Archaea and SRB utilised the vent-derived CO 2 for assimilatory biosynthesis. Our results show a shift in the microbial community towards anaerobic and acidophilic microorganisms as a consequence of the long-term exposure of the soil environment to high CO 2 concentrations.

    Aim To document the long term outcome of congenital cataract surgery with primary posterior chamber (PC) lens implantation in the first year of life. Method A retrospective review of congenital cataract surgery in the first year of life with PC lens implantation in 18 infants, eight with unilateral and 10 with bilateral cataract. The average age at surgery was 15 weeks (range 3–44 weeks). The mean follow up was 95 months (range 60–139 months). Results The best outcomes were in the bilateral group where 50% of eyes achieved 6/18 or better, with a best acuity of 6/9. Acuities were poor in the unilateral group where only 38% achieved 6/60 or better, with a best acuity of 6/24. There was a mean refractive shift between first refraction after surgery and refraction at 36 months after surgery of −3.44 dioptres with a very wide range (+2.00 to −15.50). There was a significantly greater myopic shift in the unilateral cases. Many eyes in both groups continued to show an increasing myopic shift between 36 months after surgery and their final recorded refraction. The main complications were amblyopia, especially in unilateral cataracts, and posterior capsular opacification. Amblyopia was most probably related to a combination of early onset of dense cataract in this young age group, late presentation for initial surgery, delay in capsulotomies, and imperfect compliance with a rigorous occlusion regime. Conclusion Intraocular lens implantation in infants less than 1 year of age is generally a safe procedure. The spread of final refractive error was very wide. Final refraction in the unilateral group was significantly more myopic than the bilateral group. Final acuities were often disappointing especially in the unilateral group. PMID:16597661

    PurposeTo determine the long-term surgical and visual outcomes in Indian children with early-onset glaucoma associated with Axenfeld-Rieger anomaly (ARA).MethodsThis is a retrospective analysis of 44 eyes of 24 consecutive children with early-onset glaucoma (within 3 years of age) and ARA who underwent glaucoma surgery over a 20-year period (1991-2010) by a single surgeon. Main outcome measures were pre- and postoperative intraocular pressures (IOPs), corneal clarity, visual acuities (VAs), refractive errors, success rate, time of surgical failure, and complications.ResultsThe series consisted of 38 primary combined trabeculotomy-trabeculectomy (CTT) and 6 primary trabeculectomy procedures (Schlemm's canal could not be identified in these eyes). There was a statistically significant reduction in IOP postoperatively (27.07±4.88 vs 14.88±3.62 mm Hg; P<0.0001) with a mean reduction of 45.14%. Success probability by Kaplan-Meier survival analysis was 93% till 5 years, and then 88.1%, 82.3%, 70.5%, 56.4%, and 42.3% at year 6, 7, 8, 9, and 10, respectively. Preoperative corneal edema was present in 43/44 eyes (97.72%) and cleared in 42 eyes (97.67%). There was one case each with intraoperative hyphema and with shallow chamber postoperatively and both were successfully managed successfully. There was no incidence of endophthalmitis or any other sight-threatening complication. Data on VA were available in 34 eyes (77.3%). At final follow-up visit, 15 (44.1%) eyes had best corrected VA ⩾6/18.ConclusionsPrimary CTT is safe and effective for early-onset glaucoma associated with ARA. It leads to excellent IOP control and satisfactory visual outcome.

    Purpose: To investigate initial and long-term success rate after percutaneous treatment of iliac artery occlusion with angioplasty and stent deployment. To investigate the influence of vascular comorbidity, lesion length, stent placement and lesion coverage as possible predictors of outcome. Methods: Between January 1994 and December 1999, 80 iliac recanalizations were performed on 78 patients, median age 61.1 {+-}11.5 (SD) years. All patients were followed up by clinical examinations, duplex ultrasound and intravenous digital subtraction angiography. Mean follow-up time was 2.0 {+-} 1.53 (SD) years.Multivariate Cox regression analysis was used to determine the influence of cofactors on patency. Results: One, 2 and 4 years after recanalization, primary patency was 78.1%, 74.5% and 64.0%; secondary patency was 88.8%, 88.8% and 77.9%, respectively.Patients with shorter occlusions, complete lesion coverage and patent ipsilateral femoral arteries had significantly longer patency rates.Complications included inguinal hematoma (n=1), technical failure (n=3) aortic dissection (n=1), embolic occlusions (n=7), gluteal claudication (n=1) and genital necrosis after subsequent urethral surgery in one patient with contralateral occlusion and ipsilateral overstenting of the internal iliac artery with subsequent stenosis. Complications were of permanent clinical significance in seven of 78 (9%) of the patients. In 17 (22%) cases, percutaneous reintervention was performed with angioplasty in the stent (n=16) or deployment of a new stent (n=1). Conclusion: Endoluminal stent placement has its place in an interdisciplinary therapeutic approach as a viable therapeutic alternative to major transabdominal bypass surgery and can be performed with comparable complication rates. Patients with short occlusions, patent femoral arteries, and stents covering the entire occlusion have significant longer patency.

    Background Ultrasound (US)-guided percutaneous needle electrolysis (PNE) is a novel minimally invasive approach which consists of the application of a galvanic current through an acupuncture needle. Objective To evaluate the clinical and ultrasonographic effectiveness of a multimodal programme (PNE, eccentric exercise (EccEx) and stretching) in the short term for patients with chronic lateral epicondylitis, and to determine whether the clinical outcomes achieved decline over time. Methods A one-way repeated measures study was performed in a clinical setting in 36 patients presenting with lateral epicondylitis. The patients received one session of US-guided PNE per week over 4–6 weeks, associated with a home programme of EccEx and stretching. The main outcome measures were severity of pain, disability (Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire), structural tendon changes (US), hypervascularity and patients’ perceptions of overall outcome. Measurements at 6, 26 and 52 weeks follow-up included recurrence rates (increase in severity of pain or disability compared with discharge), perception of overall outcome and success rates. Results All outcome measures registered significant improvements between pre-intervention and discharge. Most patients (n=30, 83.3%) rated the overall outcome as ‘successful’ at 6 weeks. The ultrasonographic findings showed that the hypoechoic regions and hypervascularity of the extensor carpi radialis brevis changed significantly. At 26 and 52 weeks, all participants (n=32) perceived a ‘successful’ outcome. Recurrence rates were null after discharge and at follow-up at 6, 26 and 52 weeks. Conclusions Symptoms and degenerative structural changes of chronic lateral epicondylitis are reduced after US-guided PNE associated with EccEx and stretching, with encouragingly low recurrences in the mid to long term.

    To gain a better understanding on the spatiotemporal variation of ultrafine particles (UFPs) in urban environments, this study reports on the first results of a long-term UFP monitoring network, set up in Amsterdam (NL), Antwerp (BE), Leicester (UK) and London (UK). Total number concentrations and size distributions were assessed during 1-2 years at four fixed urban background sites, supplemented with mobile trailer measurements for co-location monitoring and additional short-term monitoring sites. Intra- and interurban spatiotemporal UFP variation, associations with commonly-monitored pollutants (PM, NOx and BC) and impacts of wind fields were evaluated. Although comparable size distributions were observed between the four cities, source-related differences were demonstrated within specific particle size classes. Total and size-resolved particle number concentrations showed clear traffic-related temporal variation, confirming road traffic as the major UFP contributor in urban environments. New particle formation events were observed in all cities. Correlations with typical traffic-related pollutants (BC and NOx) were obtained for all monitoring stations, except for Amsterdam, which might be attributable to UFP emissions from Schiphol airport. The temporal variation in particle number concentration correlated fairly weakly between the four cities (rs = 0.28-0.50, COD = 0.28-0.37), yet improved significantly inside individual cities (rs = 0.59-0.77). Nevertheless, considerable differences were still obtained in terms of particle numbers (20-38% for total particle numbers and up to 49% for size-resolved particle numbers), confirming the importance of local source contributions and the need for careful consideration when allocating UFP monitoring stations in heterogeneous urban environments.

    Purpose: Staghorn renal stones are a challenging field in urology. Due to their high recurrence rates, particularly those associated with an infective process, a complete removal is the ultimate goal in their management. We report our experience with a combined approach of laparoscopic pyelolithotomy and endoscopic pyelolithotripsy, the stone clearance rate, and long-term, follow-up outcomes. Methods: From June 2012 to October 2014, nine adult patients with large staghorn renal calculi (mean size, 7.2 cm; range, 6.2–9.0 cm) underwent a combined laparoscopic and endoscopic approach. The technique comprised laparoscopic pyelolithotomy and holmium-YAG laser stone fragmentation with the use of a flexible cystoscope introduced through a 12 mm trocar. Results: The average operative time was 140 min (range, 90–190 min). The mean estimated hemoglobin loss was 0.6 mmol/l (range 0.5–0.7 mmol/l). None of the patients required an open- surgery conversion. The mean hospital stay was 4 days (range, 2–6 days). A computed tomography urogram control at 6 months of follow up did not show any stone recurrence. Conclusions: Laparoscopic pyelolithotomy combined with endoscopic pyelolithotripsy could be a therapeutic option in cases where mini-invasive procedures, that is, extracorporeal shock wave lithotripsy, ureteroscopic lithotripsy, and percutaneous nephrolithotomy (PCNL) have failed. This technique has a high stone-clearance rate (75–100%) comparable with open surgery and PCNL. However, it could be technically demanding and should be performed by skilled laparoscopy surgeons.

    The mixing layer height (MLH) is an important factor which influences exchange processes of ground level emissions. The continuous knowledge of MLH is supporting the understanding of processes directing air quality. If the MLH is located near to the ground, which occurs mainly during winter and night-time, air pollution can be high due to a strongly limited air mass dilution. Since 2006 different methods for long-term continuous remote sensing of mixing layer height (MLH) are operated in Augsburg. The Vaisala ceilometers LD40 and CL31 are used which are eye-safe commercial mini-lidar systems. The ceilometer measurements provide information about the range-dependent aerosol concentration; gradient minima within this profile mark the borders of mixed layers. Special software for these ceilometers provides routine retrievals of lower atmosphere layering from vertical profiles of laser backscatter data. The radiosonde data from the station Oberschleissheim near Munich (about 50 km away from Augsburg city) are also used for MLH determination. The profile behavior of relative humidity (strong decrease) and virtual potential temperature (inversion) of the radiosonde agree mostly well with the MLH indication from ceilometer laser backscatter density gradients. A RASS (Radio-Acoustic Sounding System) from Metek is applied which detects the height of a turbulent layer characterized by high acoustic backscatter intensities due to thermal fluctuations and a high variance of the vertical velocity component as well as the vertical temperature profile from the detection of acoustic signal propagation and thus temperature inversions which mark atmospheric layers. These data of RASS measurements are the input for a software-based determination of MLH. A comparison of the results of the remote sensing methods during simultaneous measurements was performed. The information content of the different remote sensing instruments for MLH in dependence from different weather classes was

    Tumor necrosis factor alpha (TNF-alpha) plays an important role in the pathogenesis of chronic inflammatory diseases, i.e., rheumatoid arthritis (RA), ankylosing spondylitis (AS), Crohn's disease (CD), and ulcerative colitis (UC). Anti-TNF-alpha strategies are successfully used in their treatment. However, their effect on heart function is still uncertain. The objectives of the study were to examine the acute and long-term effect of infliximab on the heart morphology and function in patients with chronic inflammatory disorders. Thirty-one patients (21 men and 10 women) were included. Ten percent of them were diagnosed with RA, 22.5 % with AS, 22.5 % with CD, and 45 % with UC, respectively. N-terminal fragment of pro-brain natriuretic peptide (NT-proBNP) was measured before and immediately after infliximab administration at the beginning of the study and in the sixth and 12th months. Echocardiography was performed at baseline and in the sixth and 12th months. There was a significant increase in NT-proBNP after the first infliximab infusion (88.40 ± 14.09 vs. 95.24 ± 14.28 pg/ml, p = 0.0046) and similar response was detected after each infusion in the sixth and 12th months. Plasma NT-proBNP slightly but not significantly decreased (88.40 ± 14.09 vs. 81.74 ± 23.14 pg/ml, p = 0.583, and 88.40 ± 14.09 vs. 56.83 ± 17.77 pg/ml, p = 0.0576, in the sixth and 12th months, respectively). There were no significant changes in echocardiographic structural and functional parameters of the left ventricle during follow-up. Plasma NT-proBNP mildly but significantly increases immediately after infliximab infusion. However, long-term infliximab administration does not deteriorate both cardiac morphology and function.

    INTRODUCTION Acute myocardial infarction (AMI) due to unprotected left main coronary artery (ULMCA) disease is clinically catastrophic although it has a low incidence. Studies on the long-term prognosis of these patients are rare. METHODS From January 1999 to September 2013, 55 patients whose infarct-related artery was the ULMCA were enrolled. Clinical, angiographic and interventional data was collected. Short-term and long-term clinical follow-up results as well as prognostic determinants during hospitalisation and follow-up were analysed. RESULTS Cardiogenic shock (CS) occurred in 30 (54.5%) patients. During hospitalisation, 22 (40.0%) patients died. Multivariate logistic regression analysis showed that CS (odds ratio [OR] 5.86; p = 0.03), collateral circulation of Grade 2 or 3 (OR 0.14; p = 0.02) and final flow of thrombolysis in myocardial infarction (TIMI) Grade 3 (OR 0.05; p = 0.03) correlated with death during hospitalisation. 33 patients survived to discharge; another seven patients died during the follow-up period of 44.6 ± 31.3 (median 60, range 0.67–117.00) months. The overall mortality rate was 52.7% (n = 29). Kaplan-Meier analysis showed that the total cumulative survival rate was 30.7%. Cox multivariate regression analysis showed that CS during hospitalisation was the only predictor of overall mortality (hazard ratio 4.07, 95% confidence interval 1.40–11.83; p = 0.01). CONCLUSION AMI caused by ULMCA lesions is complicated by high incidence of CS and mortality. CS, poor collateral blood flow and failure to restore final flow of TIMI Grade 3 correlated with death during hospitalisation. CS is the only predictor of long-term overall mortality. PMID:27439434

    Cyclosporine (CsA) is an immunosuppressive agent frequently used in the clinic for prevention of allograft rejection and for the treatment of autoimmune diseases. Despite its desired action on the immune system, CsA treatment may present serious adverse effects, which are masked by the concomitant use of other drugs. The search for effective immunosuppression protocols which does not affect the quality of life of patients is driving research to investigate the CsA involvement in vascular diseases, frequent in patients under immunosuppression. Thus, 45 non-transplanted Wistar rats were treated for 8 weeks with vehicle or 5 or 15 mg/kg CsA (n=15/group) by gavage administration to evaluate the specific influence of cyclosporine on the levels of risk factors (metabolic and inflammatory) of vascular disease and its mechanism of action. Therefore, serum insulin levels, glucose tolerance test, serum lipids profile, total homocysteine and fibrinogen levels were assessed. The biochemical alterations reported here suggest the development of a framework straight to diabetes. Glucose homeostasis was affected as indicated by decreased insulin levels and altered glucose tolerance test in CsA 15 mg/kg group compared to other groups. Serum insulin and total homocysteine levels presented a significant negative correlation (R=- 0.76, P<0.0001). Fibrinogen and serum lipids profiles were significantly increased in CsA 15 mg/kg group compared to other groups and correlated positively with total homocysteine levels. Considering the well-established correlation among insulin resistance, lipid and total homocysteine levels, hypercoagulability and atherosclerosis, we can assume that this protocol of long-term CsA treatment in non-transplanted rats alter biochemical parameters related to cardiovascular and cerebrovascular risk, mainly in CsA 15 mg/kg group. Insulin and tHcy serum levels appear to be central in this process. PMID:20188083

    The long-term efficacy and safety of adalimumab (ADA) for the treatment of intestinal Behcet’s disease (BD) in the clinical setting have not been evaluated previously. This retrospective study evaluated the 52-week efficacy of ADA in BD patients. A total of eight patients who were refractory to conventional therapy were given ADA (160/80/40 mg every other week). Marked improvement (MI) was achieved by 10 weeks in five patients (62.5%), and by 52 weeks in six patients (75%). In addition, complete remission was obtained in two patients (25%) at both 10 and 52 weeks. Improvement of global gastrointestinal (GI) symptoms to score 0 was observed in three patients (37.5%) at 10 weeks and four patients (50%) at 52 weeks. Moreover, improvement of endoscopic assessment to score 0 was also seen in four patients (50%) at both 10 and 52 weeks. No adverse events were observed in any patients during the 52 weeks. In conclusion, ADA offers an effective, well-tolerated treatment for intestinal BD in patients who are refractory to conventional therapy. PMID:26985255

    We treated 187 patients who had Graves' disease with low-dose radioactive iodide (/sup 131/I), using a protocol that included a compensation for thyroid size. The incidence of early hypothyroidism (12 per cent) was acceptably low in the first year after /sup 131/I treatment, but we found a cumulative high incidence (up to 76 per cent) at the end of the 11th year. In contrast, the incidence of permanent hypothyroidism was relatively stable in 166 surgically treated patients, increasing from 19 to 27 per cent at the end of 11 years. Among 122 medically treat
