    BACKGROUND: Lithium accumulates in the colon and inhibits the enzyme GSK-3β that possesses anti-carcinogenic effects. We therefore examined the association between lithium use and colorectal cancer risk in a nationwide study. METHODS: We used the Danish Cancer Registry to identify all patients...... diagnosed with incident colorectal adenocarcinoma during 2000-2012 (n=36 248). Using a matched case-control approach, we estimated the association between long-term use (⩾5 years) of lithium and risk of colorectal adenocarcinoma using conditional logistic regression. RESULTS: Long-term use of lithium......, 0.66-1.55; distal colon: 1.52 (95% CI, 1.05-2.20); and rectum: 0.80 (95% CI, 0.50-1.30). CONCLUSIONS: Lithium use was not associated with an overall increased risk of colorectal adenocarcinoma. The variation by subsite warrants further investigation....

    To determine if the OOPS index is predictive of long-term hearing results after ossiculoplasty. Case series with retrospective chart review. Tertiary care otology practice. Adult and pediatric patients (3-88 years of age). Ossiculoplasty with cartilage tympanoplasty, with or without mastoidectomy. Primary outcome measures included short-term hearing results (pure-tone average air-bone gap [PTA-ABG] measured between 60 days and 1 year after surgery), long-term hearing results (PTA-ABG measured ≥5 years after surgery), and the rate of successful ABG closure to ≤20 dB. Secondary measures included the need for revision surgery, delayed tympanic membrane graft failure, worsening conductive hearing loss (after an initially satisfactory hearing result), and recurrence of cholesteatoma. There was no significant difference between adults and children for short-term hearing results (average post-op PTA-ABG was 18.9 dB vs. 19.8 dB, respectively; p = 0.544), long-term hearing results (average final PTA-ABG was 19.3 dB vs. 19.4 dB, respectively; p = 0.922), or rate of ABG closure to less than 20 dB (63.1% vs. 58.0%, p = 0.282). Spearman's rank-order correlation (ρ) identified a strong positive correlation between OOPS index score and average post-operative PTA-ABG (ρ = 0.983; p hearing outcomes in adult and pediatric patients undergoing ossiculoplasty in both the short term and the long term.

    The only curative approach in pancreatic ductal adenocarcinoma (PDAC) is resection, which is possible only in 15 - 30 % of patients. Local tumor spread or distant metastases are contraindications for resection in the majority of patients. Surgical-oncological quality with short- and long-term results are varying tremendously, so that "expertise/quality" are associated to hospital- or surgeon's volume and/or center formation. The treatment results also depend, to a great extent, on the medical diagnostic quality. With our retrospective study, we aim to compare the results-quality of cooperative pancreatic cancer treatment based on an extensive preoperative diagnostic procedure for staging and risk estimation in a specialized GI-medical department and visceral surgical-oncological expertise in pancreatic cancer surgery at a general hospital with the results-quality of expert centers. Fifty-three patients with PDAC had diagnosis and resection of their cancer between 1/2002 and 12/2009. The 30 day hospital-mortality was 3.8 % and the median survival time after demission from the hospital was 23.1 months. The 5-year-survival rate of R0-resected patients, all of whom had received adjuvant chemotherapy, was high with 31 %. The survival data and the extraordinarily high resection rate of 98.1 % in the patient group, whose primary tumor stage was pT3 in 81 %, reflects the excellent cooperation of high standards in medical diagnostic processes, visceral pancreatic surgery, and adjuvant medical chemotherapy. The results are well comparable to those of "high volume centers". The responsible heads of the two departments have been trained at university expert centers. Expertise in the treatment of pancreatic cancer patients may be successfully transferred from an expert center to a general hospital, if the team has high expertise. © Georg Thieme Verlag KG Stuttgart · New York.

    A study on the long-term efficacy of femoral-popliteal angioplasty was carried out on 185 angioplasty cases over a 5 year follow-up period. A classification of data according to the type of lesion treated, revealed that results were favorable in case of stenosis (87%), short obstruction (70%) and long obstruction (35%). A special study of the outcome of treatments for stage IV arteritis was carried out. After comparing results with those obtained by other teams, the authors list the complications encountered, hematomas, and thromboses, and show their current tendency for regression. Lastly, the authors stress the advantages of angioscopy, which permits to identify the nature of the treated lesions and to predict possible complications, which are usually underrated by angiography.

    Full Text Available Amin F EllakwaMenoufiya University, Shibin el Kom, Al-Menoufiya, EgyptBackground: Rhegmatogenous retinal detachment is a commonly encountered retinal problem where rapid treatment can prevent irreversible vision loss. Pneumatic retinopexy (PR is a simple, minimally invasive procedure for retinal reattachment.Purpose: This study aimed to assess the long-term anatomical and functional outcome of pneumatic retinopexy in primary rhegmatogenous retinal detachment.Patients and methods: A prospective interventional study was performed. Subjects with rhegmatogenous retinal detachment who underwent pneumatic retinopexy from May 2006 to May 2007 at Menoufiya University Hospital were included in this study with at least 3 years follow-up.Results: A total of 40 cases were included in the study. The mean age of patients was 44.25 ± 10.85 years. Reattachment of the retina was achieved in 100% of cases. In 75% of cases, the primary intervention was successful. However, the retina redetached in 20% of these during the first 6 months, requiring reinjection or another procedure. Three years after the first intervention, follow-up measurement of the mean visual acuity of the eyes without reoperation was 0.40 ± 0.21 while the mean visual acuity of the eyes which needed additional operations was 0.22 ± 0.13.Conclusion: Sixty percent of the cases obtained long-term retinal reattachment with a single operation success (SOS, with good visual recovery and less morbidity than other more invasive procedures like scleral buckling or pars plana vitrectomy, translating to higher productivity for the patient. This procedure, being quicker than the alternatives, also saves the surgeon's time, making PR a good choice for managing primary rhegmatogenous retinal detachment in developing countries.Keywords: pneumatic, retinopexy, rhegmatogenous, retinal detachment

    Full Text Available Mandibular distraction osteogenesis has become a popular surgical modality due to its many advantages over conventional orthognathic surgical procedures. However, in spite of the technique having been used for over 15 years, no concrete long term results are available regarding the stability of results. We discuss the various studies which have reported either in favour or against the stablility of results after distraction. We report a series of 6 cases (3 unilateral and 3 bilateral distraction where distraction was carried out before puberty and followed them up to seven years after removal of distractors. This case series shows that results achieved by distraction osteogenesis are unstable or best unpredictable with respect to producing a permanent size increase in the mandible. The role of the distraction osteogenesis in overcoming the pterygomassetric sling is questionable. We suggest a multicenter study with adequate patient numbers treated with a similar protocol and documented after growth cessation to have meaningful conclusions on the debate of distraction osteogenesis versus orthognathic surgery.

    The overall 5 year survival rate for pancreatic ductal adenocarcinoma (i.e., PDAC) is a dismal 5%, although patients that have undergone surgical resection have a somewhat better survival rate of up to 20%. Very long-term survivors of PDAC (defined as patients with ≥ 10 year survival following apparently curative resection), on the other hand, are considerably less frequent. The molecular characteristics of very long-term survivors (VLTS) are poorly understood, but might provide novel insights into prognostication for this disease. In this study, a panel of five VLTS and stage-matched short-term survivors (STS, defined as disease-specific mortality within 14 months of resection) were identified, and quantitative proteomics was applied to comparatively profile tumor tissues from both cohorts. Differentially expressed proteins were identified in cancers from VLTS vs. STS patients. Specifically, the expression of galectin-1 was 2-fold lower in VLTS compared with STS tumors. Validation studies were performed by immunohistochemistry (IHC) in two additional cohorts of resected PDAC, including: 1) an independent cohort of VLTS and 2) a panel of sporadic PDAC with a considerable range of overall survival following surgery. Immunolabeling analysis confirmed that significantly lower expression of stromal galectin-1 was associated with VLTS (p = 0.02) and also correlated with longer survival in sporadic, surgically-treated PDAC cases (hazard ratio = 4.9, p = 0.002). The results from this study provide new insights to better understand the role of galectin-1 in PDAC survival, and might be useful for rendering prognostic information, and developing more effective therapeutic strategies aimed at improving survival.

    Full Text Available Abstract Background Cervical cancer is the third most common cancer in women worldwide. The most common histopathological subtype is cervical squamous cell carcinoma (SCC, 75-80%, followed by adenocarcinoma (AC and adenosquamous carcinoma (ASC; together 15-20%. Rising incidence rates of AC have been observed relative and absolute to SCC and evidence is accumulating that cervical AC is a distinct clinical entity. Cervical SCC, ASC, and AC are caused by a persistent infection with high-risk human papillomavirus (HPV and failed control of the immune system plays a pivotal role in the carcinogenesis of all three histopathological subtypes. Human leukocyte antigen E (HLA-E, a non-classical HLA class Ib molecule, plays an important role in immune surveillance and immune escape of virally infected cells. In this study we investigated HLA-E expression in three well-defined cohorts of cervical AC, ASC, and SCC patients, and determined whether HLA-E expression was associated with histopathological parameters and patient survival. Methods and results HLA-E expression was assessed by immunohistochemistry on formalin-fixed, paraffin-embedded tissue sections of 79 SCC, 38 ASC, and 75 AC patients. All patients included were International Federation of Gynaecology and Obstetrics stage I-II and underwent radical hysterectomy with lymphadenectomy as primary treatment. Significant differences between the histopathological subgroups were detected for age distribution, HPV positivity, HPV type distribution, tumour size, tumour infiltration depth, lymph-vascular space invasion, and adjuvant radiotherapy. High expression of HLA-E was found in 107/192 (56% cervical carcinomas, with significantly more overexpression in cervical AC compared to SCC and ASC (37/79 SCC, 18/38 ASC, and 52/75 AC; P = 0.010. High HLA-E expression in cervical AC was associated with favourable long term disease-specific and recurrence-free survival (P = 0.005 and P = 0

    Purpose: External-beam radiation therapy combined with low-doserate permanent brachytherapy are commonly used to treat men with localized prostate cancer. This Phase II trial was performed to document late gastrointestinal or genitourinary toxicity as well as biochemical control for this treatment in a multi-institutional cooperative group setting. This report defines the long-term results of this trial. Methods and Materials: All eligible patients received external-beam radiation (45 Gy in 25 fractions) followed 2-6 weeks later by a permanent iodine 125 implant of 108 Gy. Late toxicity was defined by the Radiation Therapy Oncology Group/European Organization for Research and Treatment of Cancer late radiation morbidity scoring scheme. Biochemical control was defined by the American Society for Therapeutic Radiology and Oncology (ASTRO) Consensus definition and the ASTRO Phoenix definition. Results: One hundred thirty-eight patients were enrolled from 20 institutions, and 131 were eligible. Median follow-up (living patients) was 8.2 years (range, 2.7-9.3 years). The 8-year estimate of late grade >3 genitourinary and/or gastrointestinal toxicity was 15%. The most common grade >3 toxicities were urinary frequency, dysuria, and proctitis. There were two grade 4 toxicities, both bladder necrosis, and no grade 5 toxicities. In addition, 42% of patients complained of grade 3 impotence (no erections) at 8 years. The 8-year estimate of biochemical failure was 18% and 21% by the Phoenix and ASTRO consensus definitions, respectively. Conclusion: Biochemical control for this treatment seems durable with 8 years of follow-up and is similar to high-dose external beam radiation alone or brachytherapy alone. Late toxicity in this multi-institutional trial is higher than reports from similar cohorts of patients treated with high-dose external-beam radiation alone or permanent low-doserate brachytherapy alone, perhaps suggesting further attention to strategies that limit doses to

    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.

    Purpose To test the hypothesis that increasing radiation dose delivered to men with early-stage prostate cancer improves clinical outcomes. Patients and Methods Men with T1b-T2b prostate cancer and prostate-specific antigen ≤ 15 ng/mL were randomly assigned to a total dose of either 70.2 Gray equivalents (GyE; conventional) or 79.2 GyE (high). No patient received androgen suppression therapy with radiation. Local failure (LF), biochemical failure (BF), and overall survival (OS) were outcomes. Results A total of 393 men were randomly assigned, and median follow-up was 8.9 years. Men receiving high-dose radiation therapy were significantly less likely to have LF, with a hazard ratio of 0.57. The 10-year American Society for Therapeutic Radiology and Oncology BF rates were 32.4% for conventional-dose and 16.7% for high-dose radiation therapy (P < .0001). This difference held when only those with low-risk disease (n = 227; 58% of total) were examined: 28.2% for conventional and 7.1% for high dose (P < .0001). There was a strong trend in the same direction for the intermediate-risk patients (n = 144; 37% of total; 42.1% v 30.4%, P = .06). Eleven percent of patients subsequently required androgen deprivation for recurrence after conventional dose compared with 6% after high dose (P = .047). There remains no difference in OS rates between the treatment arms (78.4% v 83.4%; P = .41). Two percent of patients in both arms experienced late grade ≥ 3 genitourinary toxicity, and 1% of patients in the high-dose arm experienced late grade ≥ 3 GI toxicity. Conclusion This randomized controlled trial shows superior long-term cancer control for men with localized prostate cancer receiving high-dose versus conventional-dose radiation. This was achieved without an increase in grade ≥ 3 late urinary or rectal morbidity. PMID:20124169

    Surgical tibial bypass for critical limb ischemia is associated with significant morbidity, mortality, and graft failure, whereas percutaneous angioplasty and stenting has promising results. The objective of this study was the investigation of the long term results of below-knee percutaneous angioplasty for restoring straight inline arterial flow in patients with critical limb ischemia. The clinical and angiographic data of 281 consecutive patients with critical limb ischemia treated by PTA between 2008 and 2011 was evaluated in a prospective register. The aim of the revascularization was to achieve a straight inline flow to the wound with balloon angioplasty. Stent implantation was done in the case of recoil and flow limiting dissection. Primary end points were clinical success (relief of resting pain, healing of ulceration, limb survival) and major adverse events (death, myocardial infarction, major unplanned amputation, need for surgical revascularization, or major bleeding). Secondary end points were the angiographic result of the intervention, procedural data and consumption of angioplasty equipment. The impact of diabetic leg syndrome and the result of the angioplasty on the limb salvage was also investigated. We have analysed the impact of major amputation on long term mortality. Mean age of patients was 72.5 ± 10.6 years and the follow-up period was 40.8 ± 9.7 months. Technical success was reached in 255 (90.7%) of the patient's: 255 limbs straight inline flow with good angiographic result was restored to at least one tibial vessel. Balloon angioplasty, stent implantation and rotational atherectomy was performed in 278 (98.9%), 74 (26.3%) and 2 patients (0.7%). From clinical end points the rest pain was ceased in 56.6%, the ulcer and the gangrena was healed in 73.5% and 46.5%. The long term limb survival was 73.5%; 65.8% in diabetic and 89.6% in non-diabetic leg syndrome (p = 0.001). The major adverse events at long-term follow-up occured in 122 (43

    Stereotactic psychosurgery is an effective method for treating some medically intractable psychiatric illnesses. However, it is unfamiliar and the long-term clinical results have not been reported in Asia. The long-term results of psychosurgery are evaluated and the neuroanatomical basis is discussed. Twenty-one patients underwent stereotactic psychosurgery for medically intractable psychiatric illnesses since 1993. All were referred from psychiatrists for these disorders. Two patients showed aggressive behavior, 12 had obsessive-compulsive disorder (OCD), and seven had depression with anxiety disorders. Bilateral amygdalotomy and subcaudate tractotomy were performed for aggressive behavior, limbic leucotomy was performed for OCD, and subcaudate tractotomy with or without cingulotomy was performed for depression with anxiety. OCD was evaluated with the Yale-Brown Obsessive Compulsive Scale (YBOCS), the visual analogue scale, the Clinical Global Impression Scale, and the Overt Aggression Scale (OAS). The Mini-Mental State Examination and the Wechsler Adult Intelligence Scale-Revised were used for the evaluation of aggressive behavior. The 17-item Hamilton Depression Rating Scale (HAMD) was used for evaluation of depression. Ventriculography was used in the first seven patients and magnetic resonance imaging-guided stereotaxy was used in the recent 14 cases for localization of the target. The lesions were made with a radiofrequency lesion generator. OAS scores in the two patients with aggressive behavior during follow up declined from 8 to 2 with clinical improvement. All 12 patients with OCD returned to their previous life and showed the mean YBOCS scores decreased from 34 to 3. Ten patients with OCD could be followed up (mean 45 months). All patients returned to their previous social life. In seven patients with depression with anxiety, HAMD scores declined from 28.5 to 16.5. There was no operative mortality and no significant morbidity except for one case of mild

    To report the long term results of congenital cholesteatoma of the middle ear in children. Retrospective study of thirty two children with 33 congenital cholesteatoma (1 bilateral cholesteatoma) operated on by the same surgeon. The mean age was 6 years. The most common clinical presentation was unilateral hearing loss. A trans-canal approach was performed in 4 cases and an intact canal wall technique in 29 cases. A two staged surgery was necessary in 28 patients, whom a residual cholesteatoma was observed in 7 patients. A third stage was performed in 11 patients because of a residual cholesteatoma in 2 two cases and a functional failure in 9 cases. At five years postoperative audiometry (air bone gap inferior or equal to 20 dB HL), a functional success was obtained in 50% of cases. The diagnosis of congenital cholesteatoma must be evoked in every atypical otitis media with effusion or unilateral transmission hypoacusis. The intact canal wall technique in two stages is the most appropriate treatment, since congenital cholesteatoma in children appears aggressive in a well pneumatized mastoid. The choice for an intact canal wall technique is also justified by the ambition of a conservative surgery in the young child. The functional results are generally satisfactory in early diagnosed cases. Thus, ENT and pediatric physicians have a unique role in detecting congenital cholesteatoma in the early period of life, and in ensuring a long term follow-up.

    At the Radiologic Department of the Staedt. Krankenhaus Passau, 473 patients with degenerative diseases in the big joints and the spine were irradiated with the caesium unit between 1971 and 1979. Among these patients, 249 could be followed up during a prolonged period (1/2 to 9 years, i.e. 4.2 years on an average). According to the categories of v. Pannewitz, 11% were pain-free at this moment, 21% showed an essential improvement, 29% showed an improvement, and 39% were not influenced by the treatment. 13.5% showed recurrent pains; these were mentioned as 'not influenced' in the statistical analysis. It is proved that the relief of pain does not depend on the age of the patients, but on the anamnesis period, the results of the X-ray examiantion, and the degree of the restriction of mobility. Due to the delay of irradiation, a preliminary treatment mostly produces a less favorable radiotherapeutic result. Compared with other therapeutic methods, the long term results of radiotherapy of degenerative joint diseases are generally favorable. This conclusion is also confirmed by the results of patients checked up more than five years after the treatment.

    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.

    Various techniques and materials have been proposed to deal with the problems that concern radical cavities, such as recurrence of the inflammatory process, the need for regular medication, and social inconvenience (eg, inability to practice water sports, working in an adverse enviroment). This article provides a detailed report of the results of revalidation of old radical cavities using hydroxyapatite granules as a filling. The material was incorporated with fibrin adhesive to fill the mastoid cavity and was covered with a sheet of bone pate sealant. Twenty-eight patients with chronic discharging old radical cavities were selected for this study (mean follow-up 11.4 years; range 10-14 years). At the 6-month follow-up, grafting was successful in 25 patients, whereas the functional outcomes showed an air-bone gap below 30 dB in 18 patients. No postoperative sensorineural hearing loss was observed. The long-term follow-up demonstrated a slight worsening of the initial findings; four other patients had reperforation of the tympanic membrane, and hearing deteriorated in five patients to above 30 dB air-bone gap. These results could be a consequence of an alteration in the function of the eustachian tube and of the severity of the preoperative pathologic processes.

    Pancreatic adenocarcinoma is one of the most lethal malignancies worldwide. In patients with unresectable tumor there are several strategies of palliative chemotherapy, either gemcitabine based regimens or FOLFIRINOX, which is supposed to be most efficient but also most toxic. Hence, management of toxicity is crucial to perform a therapy consisting of FOLFIRINOX. We report on a 69-year-old female patient suffering from adenocarcinoma of the pancreatic tail with multiple liver metastases. Palliative chemotherapy comprising leucovorin, fluorouracil, oxaliplatin and irinotecan (FOLFIRINOX) was initiated in February 2011 and was tolerated very well. Subsequent computed tomography-scans showed significant reduction of the tumor load in the liver as well as in the primary pancreatic tumor. The serum levels of the tumor marker CA 19-9 were elevated initially and decreased concomitantly. Thus, chemotherapy was continued for more than 3 years, and up to 72 cycles were administered until April 2014. Due to intermittent neutropenia and mucositis the initial dose was reduced to 60% of the calculated standard dose. In April 2014, an intermediate staging by computed tomography and FDG-PET revealed significant reduction of the size of the primary pancreatic tumor compared with February 2011. Liver metastases could hardly be detected anymore. After pausing chemotherapy for 12 weeks, one liver metastasis reappeared and was treated by RFA in August 2014. Meanwhile, in October 2014 there is no radiological evidence on any existing tumor or metastasis. Our report demonstrates that a sufficient tolerance of chemotherapy with FOLFIRINOX is achievable, what makes a long term treatment with FOLFIRINOX feasible and can lead to impressive results.

    Full Text Available Abstract Background Metastatic pancreatic adenocarcinoma has a short median overall survival (OS of 5–6 months. However, a subgroup of patients survives more than 1 year. We analyzed the survival outcomes of this subgroup and evaluated clinical and pathological factors that might affect survival durations. Methods We identified 20 patients with metastatic or recurrent pancreatic adenocarcinoma who received single-agent gemcitabine and had an OS longer than 1 year. Baseline data available after the diagnosis of metastatic or recurrent disease was categorized as: 1 clinical/demographic data (age, gender, ECOG PS, number and location of metastatic sites; 2 Laboratory data (Hematocrit, hemoglobin, glucose, LDH, renal and liver function and CA19-9; 3 Pathologic data (margins, nodal status and grade; 4 Outcomes data (OS, Time to Treatment Failure (TTF, and 2 year-OS. The lowest CA19-9 levels during treatment with gemcitabine were also recorded. We performed a univariate analysis with OS as the outcome variable. Results Baseline logarithm of CA19-9 and total bilirubin had a significant impact on OS (HR = 1.32 and 1.31, respectively. Median OS and TTF on gemcitabine were 26.9 (95% CI = 18 to 32 and 11.5 (95% CI = 9.0 to 14.3 months, respectively. Two-year OS was 56.4%, with 7 patients alive at the time of analysis. Conclusion A subgroup of patients with metastatic pancreatic cancer has prolonged survival after treatment with gemcitabine. Only bilirubin and CA 19-9 levels were predictive of longer survival in this population. Further analysis of potential prognostic and predictive markers of response to treatment and survival are needed.

    Bariatric surgery is performed mostly on obese women of reproductive age. Many authors have studied pregnancy outcomes after bariatric surgery. Only a small number of studies have analyzed the impact of maternity on the results of bariatric surgery. To study the effect of pregnancy on long-term outcomes of bariatric surgery. Lille University Hospital. A retrospective study was conducted on 591 women aged 18 to 42 years who had undergone laparoscopic adjustable gastric band (LAGB) surgery or laparoscopic Roux-en-Y gastric bypass (LRYGB) surgery between 1996 and 2012. A comparison of the results after a 5-year follow-up was performed between patients who became pregnant after their bariatric surgery (pregnant group, n = 84) and postoperative nonpregnant women (nonpregnant group, n = 507). At the 5-year visit, 84.8% patients were seen. The preoperative body mass index (BMI) was the same in the 2 groups (pregnant group: 47.8±6.9 kg/m(2); nonpregnant group: 47.5±7.2 kg/m(2); P = .755). The percentage of excess weight loss (%EWL) was lower in the pregnant group at 2 years (pregnant group = 45.9±24.6%; nonpregnant group = 56.9±28.6%, P = .002) but was similar at 5 years (47.7±27.7% versus 49.9±28.9%, P = .644). The decrease in co-morbidities was similar after 5 years. The gestational weight gain (GWG) was higher when the band was deflated during pregnancy (GWG =+12.7±10.5 kg) compared to the band without fluid removal (GWG =+4.9±7 kg) or laparoscopic Roux-en-Y gastric bypass (GWG =+4.4±1.1 kg) (Pbariatric surgery slows down postoperative weight loss but does not affect weight results at 5-year follow-up.

    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

    To evaluate the long-term outcome after aortoiliac kissing stent placement and to analyze variables, which potentially influence the outcome of endovascular reconstruction of the aortic bifurcation. All patients treated with aortoiliac kissing stents at our institution between April 1995 and August 2011 were retrospectively identified from a prospective single-center database. Data regarding patient characteristics (age, gender, smoking, cardio- and cerebrovascular risk factors, hyperlipidaemia, diabetes mellitus and use of antihypertensive medication), symptoms, pre-interventional examination and imaging, procedural details and follow-up were retrieved. Patency rates were calculated with Kaplan-Meier analysis. Factors affecting the patency were determined with Cox uni- and multivariate analysis. A total of 215 patients (63% men, mean age 61 ± 10 years) were included. The median follow-up period was 31 (IQR 47.1) months. Primary, primary assisted, and secondary patency rates were 97%, 97%, and 99%, respectively, at one month; 92%, 95% and 94% at four months; 75%, 86%, and 91% at two years; 70%, 81%, and 91% at 5 years; and 67%, 81%, and 91% at ten years. Younger age and previous aortoiliac treatment were predictors for reduced primary and primary assisted patency. Smoking, previous aortoiliac intervention, TASC C and D lesions were predictors for reduced secondary patency. Reconstruction of the aortoiliac bifurcation with kissing stents is feasible, safe and effective in all types of lesions with satisfying long term patencies. TASC C and D lesions are associated with a higher occlusion rate. Younger age and previous aortoiliac interventions are predictors for reduced primary and primary assisted patency. © Acta Chirurgica Belgica.

    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 tennis elbow should be made as there is lot of controversy regarding the treatment.

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

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.

In 9 eyes (64.3 %) silicone oil was removed, the average length of tamponade was 9.1 months. In this group BCVA 0,1 and worse had 6 eyes (66,7 %), 0,2-0,4 had 1 eye (11,1 %) and 0,5 or better had 2 eyes (22,2 %). Permanent silicone oil tamponade had 5 eyes (35,7 %). In group of 56 phakic eyes (100 %) with silicone oil tamponade we followed cataract progression. 26 eyes (40 %) had cataract surgery in 6 month follow up, 47 eyes (72.3 %) in 1 year follow up and 57 eyes (87.7 %) had cataract surgery in 3 years follow up. Silicone oil tamponade is the method of choice for long-term and stable retinal tamponade, which is important for good functional outcomes of the surgical intervention. The silicone oil tamponade of the retina is nowadays irreplaceable, despite of its potential risks and complications.

    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.

    The side effects following thoracic sympathectomy for primary hyperhidrosis include pain and compensatory/ reflex sweating. The aim of the study was the evaluation of the results of the endoscopic sympathicotomy with clips with emphasis on the frequency of side effects following the operation. Two-hundred-eighty-three patients were qualified to thoracic T3-T4 sympathicotomy with clips. In all cases bilateral procedure in prone position with CO2 insufflation was performed. The subjective intensity of disease was evaluated by VAS scale (0--no sweating; 10--maximal possible sweating) while the recurrence of the sweating in primary localization, intensity and dynamics of compensatory and plantar sweating were evaluated post-operatively. Follow-up data were obtained during office visits 3, 12 and 36 months after surgery. The overall follow-up response was 74.6%. There was no mortality. Perioperative morbidity included 6 cases of pneumothorax. The mean duration of surgery was 57 minutes bilaterally. The postoperative intercostal pain was present in all patients (100%) with mean duration of 21.88 days but in 72.6% of cases it did not demand any medication as early as 48 hours after surgery. Strong or very strong compensatory sweating was observed in 17.5% of cases 3 months after ETS, in 14.1% after 12 months and in 23.6% after 36 months. Thoracic sympathicotomy with clips is a safe treatment that provides satisfactory longterm results. The incidence of side-effects (intercostal pain, compensatory sweating) is high and does not change with time in most of the cases.

    Peptide receptor radionuclide therapy (PRRT) for the treatment of neuroendocrine tumours (NET) has been explored for almost two decades, but there are still few trials that have exclusively investigated well-differentiated and moderately differentiated NET arising from the respiratory tree. Thus, the aim of this study was to explore the outcome in patients affected by bronchopulmonary carcinoid (BPC) following PRRT. We retrospectively analysed 114 patients with advanced stage BPC consecutively treated with PRRT at the European Institute of Oncology, Milan, from 1997 to 2012 and followed until October 2014. The objective responses, overall survival (OS) and progression-free survival (PFS) were rated, and three different PRRT protocols ({sup 90}Y-DOTATOC vs. {sup 177}Lu-DOTATATE vs. {sup 90}Y-DOTATOC + {sup 177}Lu-DOTATATE) were compared with regard to their efficacy and tolerability. The median OS (evaluated in 94 of the 114 patients) was 58.8 months. The median PFS was 28.0 months. The {sup 177}Lu-DOTATATE protocol resulted in the highest 5-year OS (61.4 %). Morphological responses (partial responses + minor responses) were obtained in 26.5 % of the cohort and were associated with longer OS and PFS. The {sup 90}Y-DOTATOC + {sup 177}Lu-DOTATATE protocol provided the highest response rate (38.1 %). Adverse events were mild in the majority of patients. However, haematological toxicity negatively affected survival. No severe (grade 3/4) serum creatinine increase was observed. Patients treated with {sup 90}Y-DOTATOC alone more frequently showed a mild/moderate decrease in renal function. In patients treated with chemotherapy before PRRT had a shorter OS and PFS, and a higher risk of developing nephrotoxicity. In a large cohort of patients with advanced BPC treated in a ''real-world'' scenario and followed up for a median of 45.1 months (range 2 - 191 months), PRRT proved to be promising in prolonging survival and delaying disease progression.

  16. Short and long term measures of anxiety exhibit opposite results.

    Ehud Fonio

    Full Text Available Animal models of human diseases of the central nervous system, generalized anxiety disorder included, are essential for the study of the brain-behavior interface and obligatory for drug development; yet, these models fail to yield new insights and efficacious drugs. By increasing testing duration hundredfold and arena size tenfold, and comparing the behavior of the common animal model to that of wild mice, we raise concerns that chronic anxiety might have been measured at the wrong time, for the wrong duration, and in the wrong animal. Furthermore, the mice start the experimental session with a short period of transient adaptation to the novel environment (habituation period and a long period reflecting the respective trait of the mice. Using common measures of anxiety reveals that mice exhibit opposite results during these periods suggesting that chronic anxiety should be measured during the post-habituation period. We recommend tools for measuring the transient period, and provide suggestions for characterizing the post habituation period.

    Capsular contracture is a distressing complication after breast augmentation for both the patient and surgeon. Although capsular contracture is a multifactorial process, one common denominator in the successful treatment of this complication is believed to be the abatement of inflammation. Leukotriene antagonists have recently emerged as effective prophylactic agents in reactive airway diseases. A prospective study was carried out on 60 female patients (120 prostheses implanted) with mild/severe capsular contracture in at least one breast. The hardness of capsular contracture was assessed by means of the mammary compliance method. Patients received zafirlukast (Accolate®) for a 6-month period. Mammary compliance was assessed at the start of the study and thereafter monthly, during drug intake and for one year after drug withdrawal. The results show a significant decrease in breast compliance values in the first 6 months, followed by a significant increase one year after the end of drug intake. Indeed, zafirlukast-treated patients displayed a 6.93 percent reduction in mammary compliance after 1 month, 14.42 percent after 3 months, 22.05 percent after 6 months and 22.52 percent after 7 months (1 month after the withdrawal of the drug). Thereafter, mammary compliance values gradually increased. A 5.47 percent reduction in mammary compliance was observed 1 year after drug withdrawal. The present study suggests that zafirlukast may be effective in reducing breast capsule distortion in patients with long-standing contracture, though reduced capsular contracture values are strictly related to the duration of drug intake.

    AIM: C-reactive protein (CRP) is an acute-phase reactant and a known indicator of the malignant potential of the tumour. The aim of this study was to investigate the significance of preoperative CRP as a parameter of the perioperative course and long-term prognosis in patients with squamous cell carcinoma and adenocarcinoma of the oesophagus.METHODS: Serum CRP was determined preoperatively in 291 of 371 patients undergoing oesophagectomy for cancer from December 1989 to March 2004. Median patient age was 59 (28-79) year,82.5% of patients were males. Squamous cell carcinoma was diagnosed in 151(51.9%) and adenocarcinoma in 122 patients. Transhiatal oesophagectomy was done in 151 (51.9%) patients and 134 (46.0%) patients underwent the abdominothoracic procedure.RESULTS: In 127 (43.6%) patients the preoperative serum CRP concentration was within the normal range (<5 mg/dL), elevated CRP levels were measured in 164 (56.4%) patients. Tumour extension (P<0.0005)and the number of lymph nodes affected by metastatic spread (P=0.015) were significantly increased in the group with elevated CRP levels. Among the perioperative parameters both the number of blood transfusions (P =0.006) and the general complication rate (P=0.002)were higher in patients with elevated preoperative CRP levels. The long-term survival rate of 13.6 (0-109.8)mo was poorer in the group with elevated CRP levels compared to 18.9 (0-155.4) mo in the group with normal CRP levels (log-rank test:P=0.107). Multivariate analysis with backward variables selection identified preoperative CRP as an independent prognostic factor of the long-term prognosis in patients with oesophageal carcinoma, with a hazard ratio of 1.182 (95% confidence interval: 1.030-1.356).CONCLUSION: The preoperative serum CRP-level is an easily determined independent prognostic marker in patients with squamous cell carcinoma and adenocarcinoma of the oesophagus.

    Background While sarcopenia is typically defined using total psoas area (TPA), characterizing sarcopenia using only a single axial cross-sectional image may be inadequate. We sought to evaluate total psoas volume (TPV) as a new tool to define sarcopenia and compare patient outcomes relative to TPA and TPV. Method Sarcopenia was assessed in 763 patients who underwent pancreatectomy for pancreatic adenocarcinoma between 1996 and 2014. It was defined as the TPA and TPV in the lowest sex-specific quartile. The impact of sarcopenia defined by TPA and TPV on overall morbidity and mortality was assessed using multivariable analysis. Result Median TPA and TPV were both lower in women versus men (both Psarcopenia was not associated with higher risk of postoperative complications (OR 1.06; P=0.72), sarcopenia defined by TPV was associated with morbidity (OR 1.79; P=0.002). On multivariable analysis, TPV-sarcopenia remained independently associated with an increased risk of postoperative complications (OR 1.69; P=0.006), as well as long-term survival (HR 1.46; P=0.006). Conclusion The use of TPV to define sarcopenia was associated with both short- and long-term outcomes following resection of pancreatic cancer. Assessment of the entire volume of the psoas muscle (TPV) may be a better means to define sarcopenia rather than a single axial image. PMID:25925237

    2017-08-03

    We studied whether in ANCA-associated vasculitis patients, duration of AZA maintenance influenced relapse rate during long-term follow-up. Three hundred and eighty newly diagnosed ANCA-associated vasculitis patients from six European multicentre studies treated with AZA maintenance were included; 58% were male, median age at diagnosis 59.4 years (interquartile range: 48.3-68.2 years); granulomatosis with polyangiitis, n = 236; microscopic polyangiitis, n = 132; or renal limited vasculitis, n = 12. Patients were grouped according to the duration of AZA maintenance after remission induction: ⩽18 months, ⩽24 months, ⩽36 months, ⩽48 months or > 48 months. Primary outcome was relapse-free survival at 60 months. During follow-up, 84 first relapses occurred during AZA-maintenance therapy (1 relapse per 117 patient months) and 71 after withdrawal of AZA (1 relapse/113 months). During the first 12 months after withdrawal, 20 relapses occurred (1 relapse/119 months) and 29 relapses >12 months after withdrawal (1 relapse/186 months). Relapse-free survival at 60 months was 65.3% for patients receiving AZA maintenance >18 months after diagnosis vs 55% for those who discontinued maintenance ⩽18 months (P = 0.11). Relapse-free survival was associated with induction therapy (i.v. vs oral) and ANCA specificity (PR3-ANCA vs MPO-ANCA/negative). Post hoc analysis of combined trial data suggest that stopping AZA maintenance therapy does not lead to a significant increase in relapse rate and AZA maintenance for more than 18 months after diagnosis does not significantly influence relapse-free survival. ANCA specificity has more effect on relapse-free survival than duration of maintenance therapy and should be used to tailor therapy individually.

    Full Text Available INTRODUCTION Abdominal aortic aneurysm can be repaired by elective procedure while asymptomatic, or immediately when it is complicated - mostly due to rupture. Treating abdominal aneurysm electively, before it becomes urgent, has medical and economical reason. Today, the first month mortality after elective operations of the abdominal aorta aneurysm is less than 3%; on the other hand, significant mortality (25%-70% has been recorded in patients operated immediately because of rupture of the abdominal aneurysm. In addition, the costs of elective surgical treatment are significantly lower. OBJECTIVE The objective of this study is to compare long-term survival of patients that underwent elective or immediate repair of abdominal aortic aneurysm (due to rupture, and to find out the factors influencing the long-term survival of these patients. MATERIAL AND METHODS Through retrospective review of prospectively collected data of the Institute for Cardiovascular Diseases of Clinical Center of Serbia, Belgrade, 56 patients that had elective surgery and 35 patients that underwent urgent operation due to rupture of abdominal aneurysm were followed up. Only the patients that survived 30 postoperative days were included in this review, and were followed up (ranging from 2 to 126 months. Electively operated patients were followed during 58.82 months on the average (range 7 to 122, and urgently operated were followed over 52.26 months (range 2 to 126. There was no significant difference of the length of postoperative follow-up between these two groups. RESULTS During this period, out of electively operated and immediately operated patients, 27 and 22 cases died, respectively. There was no significant difference (p>0,05a of long-term survival between these two groups. Obesity and early postoperative complications significantly decreased long-term survival of both electively and immediately operated patients. Graft infection, ventral hernia, aneurysm of

    Primary adenocarcinoma of the urinary bladder is a rare neoplasm. It accounts for 1-2% of all bladder carcinomas and sometimes may be found in the bladder diverticula. Fistula between duodenum and renal pelvis is another rarity while colovesical fistula is not so uncommon. We present a case of a 40 years old man who had surgery for colovesical and duodenorenal fistula and subsequently developed adenocarcinoma of the urinary bladder.

    Short and long-term results of endovascular treatment of true bifurcational coronary stenosis were analyzed in 229 patients. 68 patients received a "provisional-T" stenting on the first stage of the study. On the next stage 40 patients received the same "provisional-T" stenting, a total bifurcational stenting was conducted in 37 patients. Only coated stents were used. Independent risk factors of "provisional-T" stenting conversion to total bifurcational stenting were revealed. There were no differences between "provisional-T" and total bifurcational stenting considering the short-term treatment results. Long-term results (12-18 months) were analyzed in 70 patients. There were no restenosis of the main artery, whereas restenosis of the lateral branch was noticed in 5.5 and 2.94%, respectively, in the groups of "provisional-T" and total bifurcational stenting. Late thrombosis was registered in 1 case from the group of total bifurcational stenting.

    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.

  16. Cecal Ligation and Puncture Results in Long-Term Central Nervous System Myeloid Inflammation.

    Directory of Open Access Journals (Sweden)

    Benjamin H Singer

    Full Text Available 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.

    Full Text Available BACKGROUND: Results showed good clinical outcomes of anterior corpectomy and fusion (ACCF for patients with cervical spondylotic myelopathy (CSM during a short term follow-up; however, studies assessing long term results are relatively scarce. In this study we intended to assess the long term clinical and radiographic outcomes, find out the factors that may affect the long term clinical outcome and evaluate the incidence of adjacent segment disease (ASD. METHODS: This is a retrospective study of 145 consecutive CSM patients on ACCF treatment with a minimum follow-up of 5 years. Clinical data were collected from medical and operative records. Patients were evaluated by using the Japanese Orthopedic Association (JOA scoring system preoperatively and during the follow-up. X-rays results of cervical spine were obtained from all patients. Correlations between the long term clinical outcome and various factors were also analyzed. FINDINGS: Ninety-three males and fifty-two females completed the follow-up. The mean age at operation was 51.0 years, and the mean follow-up period was 102.1 months. Both postoperative sagittal segmental alignment (SSA and the sagittal alignment of the whole cervical spine (SACS increased significantly in terms of cervical lordosis. The mean increase of JOA was 3.8 ± 1.3 postoperatively, and the overall recovery rate was 62.5%. Logistic regression analysis showed that preoperative duration of symptoms >12 months, high-intensity signal in spinal cord and preoperative JOA score ≤ 9 were important predictors of the fair recovery rate (≤ 50%. Repeated surgery due to ASD was performed in 7 (4.8% cases. CONCLUSIONS: ACCF with anterior plate fixation is a reliable and effective method for treating CSM in terms of JOA score and the recovery rate. The correction of cervical alignment and the repeated surgery rate for ASD are also considered to be satisfactory.

    Percutaneous pulmonary valvuloplasty is the preferred interventional procedure for pulmonary valve stenosis. The aim of this study was to evaluate the effectiveness of this technique, assess the factors leading to its success, and determine the long-term results in the pediatric population. The study included 53 patients with pulmonary valve stenosis undergoing percutaneous balloon valvuloplasty between December 1985 and December 2000. Right ventricular size and functional echocardiographic parameters, such as pulmonary regurgitation and residual transvalvular gradient, were assessed during long-term follow-up. Peak-to-peak transvalvular gradient decreased from 74 mmHg [interquartile range, 65-100 mmHg] to 20 mmHg [interquartile range, 14-34 mmHg]. The procedure was unsuccessful in 2 patients (3.77%). The immediate success rate was 73.58%. Follow-up ranged from 10 years to 24 years (median, 15 years). During follow-up, all patients developed late pulmonary regurgitation which was assessed as grade II in 58.4% and grade III in 31.2%. There was only 1 case of long-term restenosis (2.1%). Severe right ventricular dilatation was observed in 27.1% of the patients. None of the patients developed significant right ventricular dysfunction. Pulmonary valve replacement was not required in any of the patients. Percutaneous balloon valvuloplasty is an effective technique in the treatment of pulmonary valve stenosis with good long-term results. Copyright © 2013 Sociedad Española de Cardiología.

    Full Text Available Abstract Background In view of the limited data available on the conservative treatment of patients with congenital scoliosis (CS, early surgery is suggested in mild cases with formation failures. Patients with segmentation failures will not benefit from conservative treatment. The purpose of this review is to identify the mid- or long-term results of spinal fusion surgery in patients with congenital scoliosis. Methods Retrospective and prospective studies were included, reporting on the outcome of surgery in patients with congenital scoliosis. Studies concerning a small numbers of cases treated conservatively were included too. We analyzed mid-term (5 to 7 years and long-term results (7 years or more, both as regards the maintenance of the correction of scoliosis and the safety of instrumentation, the early and late complications of surgery and their effect on quality of life. Results A small number of studies of surgically treated patients were found, contained follow-up periods of 4-6 years that in the most cases, skeletal maturity was not yet reached, and few with follow-up of 36-44 years. The results of bracing in children with congenital scoliosis, mainly in cases with failure of formation, were also studied. Discussion Spinal surgery in patients with congenital scoliosis is regarded in short as a safe procedure and should be performed. On the other hand, early and late complications are also described, concerning not only intraoperative and immediate postoperative problems, but also the safety and efficacy of the spinal instrumentation and the possibility of developing neurological disorders and the long-term effect these may have on both lung function and the quality of life of children. Conclusions Few cases indicate the long-term results of surgical techniques, in the natural progression of scoliosis. Similarly, few cases have been reported on the influence of conservative treatment. In conclusion, patients with segmentation failures

    This retrospective long-term study evaluates the clinical and radiological results of the Sauvé-Kapandji procedure in rheumatoid wrists. Fourteen patients with rheumatoid arthritis who had undergone a Sauvé-Kapandji procedure were examined 10 to 16.5 years after surgery. Range of motion and grip strength were measured. The patients' complaints related with instability of the ulnar stump, the residual pain in the wrist, and the function of the operated hand were assessed. The review also included a radiological examination. Pain was found to have decreased and the gripping strength of the hand to have increased in all the patients. The range of wrist rotation was significantly improved. On radiographs, there were no signs of increased ulnar translation of the carpus. We noted no instance of subluxation or dislocation of the ulnar stump. In this long-term evaluation, the Sauvé-Kapandji procedure was found to provide long-term improvement of the function of the wrist-hand complex, by eliminating the distal radio-ulnar joint which is a major source of pain in the rheumatoid wrist.

    Endoscopic stent implantation is a common short-treatment option in palliative settings in patients with esophageal cancer. Advanced disease is associated with low survival rates; therefore, data on the long-term outcome are limited. So far, cases of long-term remission or even cure of metastasized adenocarcinoma of the gastroesophageal junction or stomach (AGS) have only been reported from Asia. A 51-year-old male patient primarily diagnosed with metastasized adenocarcinoma of the gastroesophageal junction (GEJ) [type I, cT3cN+cM1 (hep), CEA positive, UICC stage IV] received palliative esophageal stenting with a self-expandable metal stent. As disease progressed after four cycles with epirubicin, oxaliplatin, and capecitabin, treatment was changed to 5-FU and Irinotecan. The patient did not return after 5 cycles of FOLFIRI, but presented 4 years later with mild dysphagia. Endoscopy surprisingly revealed no relevant stenosis or stent migration. Repeated histological analyses of a residual mass at the GEJ did not detect malignancy. Since the initially diagnosed hepatic metastases were no longer detectable by computed tomography, cure from esophageal cancer was assumed. Dysphagia was ascribed to esophageal motility disorder by a narrowed esophageal lumen after long-term stenting. Thus, endoscopic stent implantation is an important method in palliative treatment of dysphagia related to AGS. New systemic treatment strategies like trastuzumab in Her2neu positive cases or new VEGF-inhibitors like ramucirumab will lead to more long-time survivors with AGS. In conclusion, future endoscopic treatment strategies in AGS represent a challenge for the development of new stent techniques in either extraction or programmed complete dissolution. PMID:27462189

    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

    Conventional treatment of anal abscess by a simple drainage continues to be routine in many centers despite retrospective and randomized data showing that primary fistulotomy at the time of abscess drainage is safe and efficient. The purpose of this study is to report the long-term results of fistulotomy in the treatment of anal abscesses. This is a prospective nonrandomized study of 165 consecutive patients treated for anal abscess in University Hospital Hassan II, Fez, Morocco, between January 2005 and December 2010. Altogether 102 patients were eligible to be included in the study. Among them, 52 were treated by a simple drainage and 50 by drainage with fistulotomy. The results were analyzed in terms of recurrence and incontinence after a median follow-up of 3.2 years (range 2-6 years). The groups were comparable in terms of age, gender distribution, type and size of abscess. The recurrence rate after surgery was significantly higher in the group treated by drainage alone (88 %) compared to other group treated by drainage and fistulotomy (4, 8 %) (p fistulotomy group (5 % vs 1 %), although this difference was not significant (p = 0.27). In the group treated by drainage and fistulotomy, high fistula tract patients are more prone to develop incontinence and recurrence, mainly within the first year. A long-term follow-up seems not to influence the results of fistulotomy group. These findings confirm that fistulotomy is an efficient and safe treatment of anal abscess with good long-term results. An exception is a high fistula, where fistulotomy may be associated with a risk of recurrence and incontinence.

    Full Text Available Background: To compare long term results of laparoscopic and endoscopic exploration of common bile duct, to assess post-procedure quality of life. Materials and Methods: From September 1992 to August 2003, we performed 4058 cholecystectomies, out of which 479 (11.80% patients had choledocholithiasis. There were 163 males and 316 females. Mean age was 63.65 ± 5.5 years. These patients were put in two groups. In the first group of 240 patients, a majority of patients underwent two-stage procedures. ERCP/ES was performed in 210 (87.50% cases. In the second group of 239 patients, a majority of patients underwent single-stage procedures. ERCP/ES was done in 32 (13.38% cases. Results: Mortality was zero in both groups. Morbidity was 15.1% in first group and 7.5% in second group. Mean hospital stay was 11.7 ± 3.2 days in first group and 6.2 ± 2.1 days in second group. Average operative time was 95.6 ± 20 minutes in first group and 128.4 ± 32 minutes in second group. Completed questionnaires received from 400 (83.50% patients revealed better long-term results in the second group. Clinical features of low-grade cholangitis were seen in 20% of patients who underwent ES. Hence the post-procedure quality of life in patients who underwent single-stage procedures was definitely much better, because of minimal damage of sphincter of Oddi. Conclusions: Single-stage laparoscopic operations provide better results and shorter hospital stay. Damage to sphincter of Oddi should be minimal, to avoid long-term low-grade cholangitis. In young patients, the operation of choice should be single-stage laparoscopic procedure with absolutely no damage to sphincter of Oddi.

    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.

    Full Text Available Objectives. To observe the short- and long-term outcomes after percutaneous coronary intervention (PCI in octogenarians (>80 y.o. at our institution. Method. All octogenarians who underwent PCI during the study period were retrospectively retrieved from our database and clinically followed. Major adverse cardiac (and cerebral events (MAC(CE was considered as primary outcome. Results. From January 2003 to December 2007, 140 octogenarians (mean age: 85±3 y.o., 79% of male underwent PCI and were clinically followed 14±11 months. Procedural success was obtained in 100 percent of patients with single vessel disease, in 96 percent of patients with double vessel disease, and in 75 percent of patients with triple vessel disease. In-hospital, 30 days, and one year MACE rates were 5%, 5%, and 10.7%, respectively. Impaired left ventricular (LV ejection fraction (hazard ratio (HR=0.909, 95% confidence interval (CI=0.856 to 0.964, =.002, diabetes mellitus (HR=5.792, 95%  CI=1.785 to 18.796, =.003, and low GFR (HR=2.943, 95%  CI=1.161, to 7.464, =.023 were independently associated with an increase risk of MACE at long-term followup. Conclusion. Coronary angiography can be successfully performed in elderly patients with single and double vessel disease. The results in triple vessel disease are encouraging. Low LV function, diabetes, and impaired renal function increase the risk of long-term major adverse cardiac events.

    Purpose. To report a comparative prospective long-term functional analysis after Riboflavin UV A corneal cross-linking (CXL) in three different age groups of patients affected by progressive keratoconus (KC). Methods. Functional analysis comprised paediatric patients (≤18 years) included 152 eyes (29.5%); intermediate group (19-26 years) 286 eyes (55.4%), and adults (≥27 years) 78 eyes (15.1%). CXL was performed according to the Siena protocol by using the Vega CBM (Caporossi-Baiocchi-Mazzotta) X linker (CSO, Florence, Italy) at Siena University by the same authors. Pre- and post-op examinations included UCVA, BSCVA, corneal topography, and surface aberrometry (CSO Eye Top, Florence, Italy), at 48 months followup. Results. At 48 months followup paediatrics, intermediate, and adult patients showed a mean gain in UCVA of +0.2, +0.14 and +0.12 Snellen lines. BSCVA gained by a mean of +0.21, +0.2, and +0.1 Snellen lines. K(max) was reduced by a mean value of -0.9 D, -0.6 D, and -0.5 D, respectively. Coma values improved by a mean of -0.45 μm, -0.91 μm, and -0.19 μm, respectively. Treatment ensured a long-term keratoconus stabilization in over 90% of treated patients. Conclusion. According to our long-term comparative results, epithelium-off Riboflavin UV A cross-linking should be the first choice therapy of progressive KC, particularly in paediatric age and patients under 26 years.

    Living donor liver transplantation (LDLT) is an alternative to conventional transplantation given its excellent results. The aim of this study is to evaluate long-term outcomes in LDLT recipients. 100 consecutive THDV recipients from the Hospital Clínic of Barcelona from March 2000 to October 2015 were included. The main indication for transplantation was end-stage liver disease (58%) followed by hepatocellular carcinoma (41%). 95% of grafts consisted of the right liver of the donor and the 5% of the left liver. After a median follow-up of 65.5 months, patient and graft survival at 1, 3, and 5 years was 93%, 80% and 74% and 90%, 76%, and 71%, respectively. The overall re-transplant rate was 9%. The most common long-term complication was biliary stenosis (40%) with an average time of onset of 13.5±12 months, with repeated admissions and an average of 1.9±2 endoscopic procedures and 3.5±3 Radiological procedures per patient. The definitive treatment was radiological dilation in 40% of cases, surgical intervention in 22.5% and re-transplantation in 7.5%. Given the long-term results, LDLT is confirmed as an alternative to conventional transplantation. However, the high rate of late biliary complications involves repeated admissions and invasive treatments that, while not compromising survival, can affect the patient's quality of life.

    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.

    Glomus tumors usually display indolent behavior, and the effectiveness of radiation in stopping their growth can be assessed after long-term follow-up. Currently only midterm results of radiosurgery are available, so the authors included patients treated by Gamma Knife at least 10 years ago in this study to obtain a perspective of long-term results. During the period from 1992 to 2003, the Gamma Knife was used to treat 46 patients with glomus tumors. The age of the patients ranged from 21 to 79 years (median 56 years). Gamma Knife radiosurgery was the primary treatment in 17 patients (37%). Open surgery preceded radiosurgery in 46% of cases, embolization in 17%, and fractionated radiotherapy in 4%. The volume of the tumor ranged from 0.2 to 24.3 cm(3) (median 3.6 cm(3)). The minimal dose to the tumor margin ranged between 10 and 30 Gy (median 20 Gy). One patient was lost for follow-up after radiosurgery. Clinical follow-up was available in 45 patients and 44 patients were followed with MRI in a follow-up period that ranged from 12 to 217 months (median 118 months). Neurological deficits improved in 19 (42%) of 45 patients and deteriorated in 2 patients (4%). Tumor size decreased in 34 (77%) of 44 patients with imaging follow-up, while an increase in volume was observed in 1 patient (2%) 182 months after radiosurgery and Gamma Knife treatment was repeated. One patient underwent another Gamma Knife treatment for secondary induced meningioma close to the glomus tumor 98 months after initial radiosurgical treatment. Seven patients died 22-96 months after radiosurgery (median 48 months), all for unrelated reasons. Radiosurgery has proved to be a safe treatment with a low morbidity rate and a reliable long-term antiproliferative effect.

    To analyze the long-term objective, perceptive, and subjective outcomes after endoscopic polydimethylsiloxane (PDMS) injection laryngoplasty in unilateral vocal fold paralysis. A retrospective study carried out between January 2008 and January 2012. Head and Neck Department, University Hospital of Modena, Modena, Italy. This was a retrospective analysis of 26 patients with unilateral vocal fold paralysis who underwent endoscopic injection of PDMS under general anesthesia. A voice evaluation protocol was performed for all patients, which included videolaryngostroboscopy, maximum phonation time, fundamental frequency, analysis of the harmonic structure of the vowel /a/ and the word /aiuole/, Grade of Dysphonia, Instability, Roughness, Breathiness, Asthenia, and Strain scale, and Voice Handicap Index. The protocol was performed before surgery, in the immediate postoperative period, and at least 3 years after surgery. The mean follow-up period was 73 months (range 39-119 months). The statistical analysis showed a significant improvement (P < 0.01) for all of the objective, perceptive, and subjective parameters by comparison between the preoperative and long-term follow-up data; moreover, no statistically significant difference was found between the postoperative and long-term follow-up data. This indicates that injection laryngoplasty with PDMS guarantees long-lasting effects over time. No complications were reported in our series. Injection laryngoplasty with PDMS can be considered to be a minimally invasive and safe technique for the treatment of unilateral vocal fold paralysis. Moreover, it allows very good and stable results to be obtained over time, avoiding repeated treatments and improving the quality of life of the patients. Copyright © 2017 The Voice Foundation.

    Full Text Available Purpose: To estimate the value of LINAC-based stereotactic radiosurgery (SRS for the long-term local control of unilateral acoustic neuromas. Materials and Methods: Twenty patients (median age 66; range 57-80 years with unilateral acoustic neuroma underwent LINAC-based SRS from May 2000 through June 2004 with a dose of 11-12 Gy. The follow-up period ranged from 36 to 84 months (median follow-up period: 55 months. Before SRS none of the patients had useful hearing. The follow-up consisted of repeat imaging studies and clinical examination for assessment of facial and trigeminal nerve function at 6-month intervals for the first year and yearly thereafter. Results: Eleven tumors (58% decreased in size and eight (42% remained stable. One tumor showed a minor increase in size on the MRI done 6 months after SRS in comparison with the pretreatment MRI; however, a subsequent decrease was noticed on the next radiographic assessment and the tumor remained stable from then on. None of the tumors increased in size in the long-term follow-up, thus giving an overall growth control of 100% for the patients in this study. None of the patients had useful hearing before SRS, so hearing level was not assessed during follow-up. No patient developed new, permanent facial or trigeminal neuropathy. Conclusion: LINAC-based SRS with 11-12 Gy provides excellent tumor control in acoustic neuroma and has low toxicity even after long-term follow-up.

    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.

    Since the beginning of 1998, eleven patients have been treated by osteodistraction to correct hypoplasia of the maxilla and midface of various origins. Among them were six patients who were treated by high LeFort I osteotomies and insertion of subcutaneous intraoral distraction devices in the malar region. In the remaining five patients extraoral distraction devices were applied after LeFort I, II and III osteotomies. Distraction osteogenesis was successful in all cases, resulting in a mean sagittal bone gain measured parallel to the skull base of 9.5 mm (range 4.5-12.0) in the group treated with intraoral distractors and a mean of 19.4 mm in the extraoral distraction group (range 15.0-25.0). All patients were kept under orthodontic supervision before, during, and after osteodistraction. In eight patients long-term cephalometric and clinical evaluation after a mean follow-up period of 24 months in the intraoral distraction group (range 22-26) and 12 months in the extraoral distraction group (range 10-14) show stable results concerning the skeletal and dental relations. Long-term follow-up is necessary.

Long-term cephalometric and clinical evaluation after a mean follow-up period of 24 months in the intraoral distraction group (range 22-26) and 12 months in the extraoral distraction group (range 10-14) show stable results concerning the skeletal and dental relations. Long-term follow-up is necessary.

    Aim: To determine the long-term outcome, effectiveness and patient satisfaction of congenital penile curvature correction by plication of tunica albuginea. Methods: From January 1992 to January 2002, 106 young patients underwent surgical correction of congenital penile curvature by corporeal plication. Indications for operation were difficult or impossible vaginal penetration and cosmetic problems. The technique of corporeal plication consists of placing longitudinal plication sutures of 2-zero braided polyester on the convex side of the curvature until the curvature is corrected when erection is artificially induced. Results of this procedure were obtained by retrospective chart reviews and questionnaires via mail. Long-term follow-up ranged from 11 to 132 (mean 69.3) months and data were available for 68 patients. Results: Penile straightening was excellent in 62 patients (91%) and good with less than 15 degree of residual curvature in 6 patients (9 %). Sixty-seven patients reported no change in erectile rigidity or maintenance postoperatively, while 1 described early detumescence. Shortening of the penis without functional problems was noted by 26 patients (38 %). Thirty-Five patients (51%) reported feeling palpable indurations (suture knots) on the penis. Temporary numbness of glans penis was described in 3 patients. Overall, 60 patients were very satisfied, 6 satisfied, 2 unsatisfied. Conclusion: Corporeal plication is an effective and durable procedure with a high rate of patient satisfaction. (Asian J Androl 2004 Sep; 6: 273-276)

    Full Text Available The goal of therapy for rheumatoid arthritis (RA is to suppress inflammation, to prevent or delay destructive changes in the joints, and to normalize functions during the longest monitoring of the course of RA. The data of randomized controlled trials and national registries are of great importance to a clinician. The paper reviews the literature data characterizing the long-term results of RA therapy with the tumor necrosis factor-α inhibitor golimumab (GLM and patient compliance with the therapy. Treatment with GLM at the registered subcutaneous dose of 50 mg once every 4 weeks gives rise to an effect in the vast majority of patients regardless of the type of previous ineffective therapy, the dose of concurrently administered methotrexate, the number of previous ineffective disease-modifying antirheumatic drugs, and the use and nonuse of glucocorticoids. GLM is characterized by a long-term (as long as 5 years effect with suppressed progression of destruction, functional recovery, and satisfactory tolerability with no additional risk for adverse events as the therapy is continued.

    Surgical resection followed by radiotherapy can be considered like the optimal treatment modality for limited esthesioneuroblastoma. However, therapeutic management of locally advanced tumors remains a challenge. The aim of our study was to access and compare the oncologic results of the different treatment modalities in advanced esthesioneuroblastoma. We performed a systematic review using the Medline, and Cochrane database in accordance with PRISMA criteria and included all the cases of advanced esthesioneuroblastoma published between 2000 and 2013. We also retrospectively included 15 patients with an advanced esthesioneuroblastoma managed at our tertiary care medical center. Long-term survival rates defined as the time from diagnosis or randomization to the date of death or last follow-up were evaluated for each treatment with Kaplan-Meier survival curve analyses. 283 patients have been included. The mean follow-up was 78 months. Five-year highest survival rates were obtained in patients treated by surgery associated with radiotherapy. Ten-year highest survival rates were obtained in patients treated by the association of surgery, radiotherapy and chemotherapy (p = 0.0008). Within the surgical group, 5-year highest survival rates were obtained in patients treated by endoscopic resection (p = 0.003). Surgical resection combined with radiotherapy offers the gold standard of care. Adjuvant chemotherapy seems to improve the long-term survival in patients with locally advanced esthesioneuroblastoma. Endoscopic resection in advanced tumors should be discussed on a case-by-case basis.

    The indications for liver transplantation among patients with post-hepatitis B virus (HBV)-related cirrhosis have changed over the past 35 years. We reviewed the long-term results of 47 patients treated with liver transplantation for HBV-related cirrhosis. Patients were classified into 3 groups according to the perioperative regimen. In the initial experience, no immunoprophylaxis was adopted (no-IP; n=5). From 1988-1996, an immunoprophylaxis scheme was adopted (HBIg; n=16). From 1997-2007, we adopted the combination of lamivudine and HBIg (LAM-HBIg; n=26). We calculated the prevalence of serological reinfection and patient survival at 1 to 20 years, using the 3 regimens. The recurrence rate was 75% in the group of untreated patients; 30% in the HBIg group; and 9% in the LAM-HBIg group. The overall survival was 67% at 5 years, and 64% at 10 and 20 years. The long-term survival for each of the 3 therapeutic approaches, namely, for the patients who did not receive any treatment, for the HBIg group, and for the LAM-HBIg group, were 20%, 50%, and 84%, respectively. We suggest to use the LAM-HBIg combination.

    The predominant treatment modality for meningioma is surgical resection. However, gamma knife radiosurgery is also an important treatment modality for meningioma that is small or cannot be completely removed because of its location. In this study, we evaluated the effectiveness and long-term results of radiosurgical treatment for meningioma in our institution. We studied 628 patients (130 men and 498 women) who underwent gamma knife radiosurgery for intracranial meningioma, which is radiologically diagnosed, from Jan 2008 to Nov 2012. We included patients with single lesion meningioma, and followed up after 6 months with imaging, and then at 24 months with a clinical examination. Patients with high-grade meningioma or multiple meningiomas were excluded. We analyzed each of the factors associated with progression free survival. The median patient's age was 56.8 years. Maximal dosage was 27.8 Gy and marginal dosage was 13.9 Gy. The overall tumor control rate was 95%. Twenty-eight patients (4.4%) showed evidence of tumor recurrence. Ninety-eight patients (15%) developed peritumoral edema (PTE) after gamma-knife surgery; two of them (2%) underwent surgical resections due to PTE. Nine patients had craniotomy and tumor removal after gamma knife surgery. Gamma knife surgery for intracranial meningioma has proven to be a safe and effective treatment tool with successful long-term outcomes. Gamma knife radiosurgery can be especially effective in cases of remnant meningioma after surgical resection or where PTE is not present.

    Full Text Available Abstract 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 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.

    The analysis of immediate and long-term results of the surgical treatment of 286 patients, operated for traumatic mandibular fractures in the Department of Oral and Maxillofacial Surgery, National O. O. Bogomolets Medical University. In 67% of patients the anatomical shape of the bone was adequately restored. The presence of residual displacements in other cases was determined by the fracture type and localization, the technical complexity of the surgical intervention, lack of fixation rigidity under certain functional load conditions. In long terms of observation the infection and inflammatory complications were observed in 13.4% of patients, delayed unition and non-unition of bone fragments occurred--in 4.7%, arthosis with persistent dysfunction of the temporomandibular joint--in 6.7%, fibrous ankylosis--in 1.3%. Secondary displacement of fragments was observed in 23.5% of patients due to insufficient stiffness and reliaability of the bone-fixatorsystem. The non-precise reposition of fragments and secondary displacements in the early and late postoperative period were the main cause of occlusal disturbances of various severities, noted in 28% of operated patients, limitation of mouth opening (10%), TMJ disorders and changes in masticatory stereotype (33%), the sensation of pain and discomfort in tough food chewing (35%). A statistical analysis of the effectiveness of different osteosynthesis methods depending on the type and localization of the fracture was carried out and recommendations for usage of fixation devices in clinical practice were given.

    A well-mastered technique will cause percutaneous transluminal angioplasty of iliac arteries to achieve long-term results comparable to those obtained surgically. In isolated iliac stenosis, a 95% good result rate is attained (81% cured, 14% improved). More complex cases of iliac stenosis yield 90% good results (72% cure), with a mean Doppler ankle/arm pressure index gain of 0.5 point in a series including 673 patients at 5 years follow-up. Only the presence of combined distal femoral lesions may cause the good result score to drop to 85%, including merely 35% cure. General complications are practically lacking and local complications are minimal, which incites one to propose this technique as a first-line treatment of iliac stenosis whenever distal blood circulation is maintained.

    Pauwels' femoral osteotomy is a classical and joint-preserving method for osteoarthritis of the hip caused by acetabular dysplasia and/or subluxation. However, its application for terminal-stage osteoarthritis of the hip, and the long-term results, have not yet been reported. We herein aim to investigate the long-term results of valgus osteotomy for terminal-stage osteoarthritis of the hip. Eighty-two hips of 75 patients (74 women and 1 man, mean age: 48.1 years) classified as having terminal-stage osteoarthritis by Kellgren and Laurence were indicated for valgus osteotomy from 1984 to 1993. Sixty-three hips of 57 patients were followed for more than 20 years (mean: 298 months). Follow-up rate was 77%. Preoperative mean hip score (Harris Hip Score) was 46.4 points. Thirty-two hips were later converted to total hip arthroplasty (THA) (mean: 185 months after surgery). Of the hips without conversion to THA, 31 hips scored 72.8 points on average, and 21 hips scored 70 or more points at the final follow-up. Kaplan-Meier survivorship analysis revealed that 40% of the hips, classified as non-atrophic type (according to Bombelli's classification) at the time of operation, maintained their joint space width for 20 years (endpoint: less than 1 mm at the weight-bearing segment, i.e., recurrence of osteoarthritis) and also revealed that 60% of the hips were not converted for 20 years after the initial operation (endpoint: conversion to THA). Cox's proportional hazard model revealed that those with the atrophic type had a hazard risk 24 times greater than those with the non-atrophic type of osteoarthritis. This is the first report of the long-term results of osteotomy for terminal-stage osteoarthritis of the hip showing satisfactory results with a lengthy follow-up period. Pauwels' valgus femoral osteotomy for terminal-stage osteoarthritis, excluding atrophic type, could be an acceptable alternative to THA.

    Full Text Available Abstract 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

    A total of 67 teeth in 64 patients were treated with apicectomy and retrograde fillings. They were randomized to receive fillings of amalgam or glass ionomer cement in a comparative clinical study. Healing was evaluated clinically and radiographically after 1 and 5 years. Evaluation showed no difference in healing capacity between the two materials. Overall success rates in both groups were registered as 90% at 1 year and 85% at 5 years. Contamination with blood or saliva during insertion of the filling material did not affect healing adversely. The study shows that the 5-year follow-up result can be predicted in more than 95% of the cases at the 1-year follow-up. It can be concluded that glass ionomer cement is a valid alternative to amalgam as an apical sealant after apicectomy with equally good long-term clinical results.

    Full Text Available Purpose: The evaluation of long-term results of punctal plugs applied to dry eye patients and the potential problems they may bring about. Material and Method: In this study, we retrospectively assessed 30 eyes of 15 patients with moderate to advanced dry eyes who were applied punctal plug (5 mm for treatment purpose and were observed for 12 months. The patients’ Ocular Surface Disease Index (OSDI scoring, Schimer-1 test (without topical anesthesia, tear film break-up time (TBUT and ocular surface staining with fluorescein results were evaluated and compared before and after 6- and 12-month use of punctal plug. The patients were started on topical antiinflammatory treatment and artificial tears two months before the application of the punctum plug. Results: The patients’ average age was 56.4±2.3 (range: 36-70 years, and the average follow-up period was 15 (12-30 months. The average OSDI score was statistically significantly decreased at 6 and 12 months when compared to the initial value (p<0.05. The average Schirmer-1 test values measured at 6 and 12 months were also statistically significantly increased compared with the initial value (p<0.05. The average Schirmer-1 test value at 12 months was considerably increased when compared with the 6th month’s value (p<0.05. The average TBUT was statistically significantly increased when compared to the values at 6 and 12 months (p<0.05. When the outcomes of ocular surface staining with fluorescein were evaluated, a significant decrease was seen at 6 and 12 months when compared to the initial value (p<0.05. Discussion: The punctal plug treatment associated with topical anti-inflammatory treatment for moderate and advanced dry eye patients is a reliable method. It decreases the dry eye symptoms and findings in the long term. (Turk J Ophthalmol 2011; 41: 225-9

    Full Text Available OBJECTIVE: To assess the short- and long-term results of the use of streptokinase (SK for the treatment of thromboses in cardiac valvular prostheses. METHODS: Seventeen patients with cardiac prosthetic thrombosis diagnosed by clinical, echocardiographic, and radioscopic findings underwent fibrinolytic treatment with a streptokinase bolus of 250,000 U followed by 100.000 U/hour. Short- and long-term results were assessed by radioscopy and echocardiography. RESULTS: Of the 17 patients, 12 had mechanical double-disk prostheses (4 aortic, 6 mitral, 2 tricuspid, 4 had single-disk prostheses (2 aortic, 1 mitral, and 1 tricuspid, and 1 had a tricuspid bioprosthesis. The success rate was 64.8%, the partial success rate was 17.6%, and the nonsuccess rate was 17.6%. All patients with a double-disk prosthesis responded, completely or partially, to the treatment. None of the patients with a single-disk prosthesis had complete resolution of the thrombosis. The time of streptokinase infusion ranged from 6 to 80 hours (mean of 56 h. The mortality rate due to the use of streptokinase was 5.8% and was secondary to cerebral bleeding. During streptokinase infusion, 3 (17.6% embolic episodes occurred as follows: 1 cerebral, 1 peripheral, and 1 coronary. The rethrombosis index was 33% in a mean follow-up of 42 months. CONCLUSION: The use of fibrinolytic agents was effective and relatively safe in patients with primary thrombosis of a double-disk prosthesis. A fatal hemorrhagic complication occurred in 1 (5.8% patient, and embolic complications occurred in 3 (17.6% patients. In a mean 42-month follow-up, 67% of the patients were free from rethrombosis.

    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.

    Full Text Available To evaluate the long-term results of surgery for choledohal cyst in adulthood, a series of 13 patients over the age of 16 operated on for choledochal cyst during a period of six years and followed-up for a minimum of 3 years was analyzed. Patients with type I and IVa cysts underwent extrahepatic cyst resection and Roux-en-Y hepatico-jejunostomy. Choledochoceles (type III were managed endoscopically. No operative mortality or morbidity occurred. Type I and III cysts showed almost ideal follow-up with no sign of stricture on HIDA scan. One type IVa cyst patients developed recurrent cholangitis due to anastomotic stricture, managed percutaneously. Whenever possible, complete cyst resection and Roux-en-Y reconstruction is the treatment of choice for all extrahepatic biliary cysts. Intra- and extrahepatic dilatations are adequately treated by extrahepatic resection and careful endoscopic or radiologic surveillance. Small choledochoceles can be safely managed by endoscopic sphincterotomy.

    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 60 mo. 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 12 mo, 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 60 mo in LASEK and PRK group respectively. Manifest refraction at 60 mo follow-up was-0.01 and 0.26 in LASEK and PRK group respectively. In the LASEK group mean UDVA and mean CDVA after60 mo were 20/22 and 20/20 respectively(P >0.01). In the PRK group mean UDVA and mean CDVA at 60 mo 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 were1.25 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.

    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.

    AIM: To evaluate the long-term outcome of standard 5-FU based adjuvant or neoadjuvant radiochemotherapy and to identify the predictive factors, especially anemia before and after radiotherapy as well as hemoglobin increase or decrease during radiotherapy.METHODS: Two hundred and eighty-six patients with Union International Contre Cancer (UICC) stage Ⅱ and Ⅲ rectal adenocarcinomas, who underwent resection by conventional surgical techniques (low anterior or abdominoperineal resection), received either postoperative (n = 233) or preoperative (n = 53)radiochemotherapy from January 1989 until July 2002.Overall survival (OAS), cancer-specific survival (CSS),disease-free survival (DFS), local-relapse-free (LRS) and distant-relapse-free survival (DRS) were evaluated using Kaplan-Meier, Log-rank test and Cox's proportional hazards as statistical methods. Multivariate analysis was used to identify prognostic factors. Median follow-up time was 8 years.RESULTS: Anemia before radiochemotherapy was an independent prognostic factor for improved DFS (risk ratio 0.76, P=0.04) as well as stage, grading, R status (free radial margins), type of surgery, carcinoembryonic antigen (CEA) levels, and gender. The univariate analysis revealed that anemia was associated with impaired LRS (better local control) but with improved DFS. In contrast,hemoglobin decrease during radiotherapy was an independent risk factor for DFS (risk ratio 1.97, P = 0.04).During radiotherapy, only 30.8% of R0-resected patients suffered from hemoglobin decrease compared to 55.6% if R1/2 resection was performed (P=0.04). The 5-year OAS, CSS, DFS, LRS and DRS were 47.0%, 60.0%,41.4%, 67.2%, and 84.3%, respectively. Significant differences between preoperative and postoperative radiochemotherapy were not found.CONCLUSION: Anemia before radiochemotherapy and hemoglobin decrease during radiotherapy have no predictive value for the outcome of rectal cancer. Stage,grading, R status (free radial margins), type of

    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

    To report the long-term results of corneal collagen crosslinking (CXL) treatment for post-laser in situ keratomileusis (LASIK) ectasia. Turkiye Hospital Eye Clinic and Fatih University Medical Faculty, Department of Ophthalmology, Istanbul, Turkey. Retrospective case series study. Consecutive patients with ectasia after LASIK were treated with CXL. The main outcome measures were uncorrected (UDVA) and corrected (CDVA) distance visual acuities, spherical and cylindrical refractions, and simulated keratometry (K) values. The study enrolled 20 eyes (14 patients; 7 women) with a mean age of 34.8 years ± 6.0 (SD) (range 25 to 45 years) and mean follow-up of 42 months (range 36 to 60 months). The UDVA and CDVA improved significantly, from 0.78 ± 0.61 logMAR to 0.53 ± 0.36 logMAR (P=.007) and from 0.27 ± 0.23 logMAR to 0.19 ± 0.13 logMAR, respectively (P≤.028). No eye lost 1 or more Snellen lines of UDVA or CDVA. Although the mean spherical refraction was not significantly different at the last visit (P=.074), the mean cylindrical refraction decreased significantly (P=.036). The maximum K value decreased from 46.0 ± 4.4 diopters (D) at baseline to 45.6 ± 3.8 D at the last visit (P=.013). By the last visit, the maximum K value decreased (≥1.0 D) in 5 eyes and remained stable in 15 eyes. No serious complications occurred. Corneal collagen crosslinking yielded long-term stability in cases with post-LASIK corneal ectasia without significant side effects. Improvements in visual acuity, cylindrical refraction, and maximum K values occurred. No author has a financial or proprietary interest in any material or method mentioned.

    Objective: To evaluate the long-term outcome of Polytetrafluoroethylene (PTFE) conduit in nerve repair and to provide more evidence in view of its potential application to achieve a satisfactory functional recovery in clinical settings. Methods: Thirty-six Wistar rats had their right sciatic nerve transected and were repaired with either conventional microsuture technique (Control group, n=18) or a PTFE conduit with a gap of 5 mm left between the nerve stumps (PTFE group, n=18). At 6 and 9 months after the operation, electrophysiological assessment and measurement of gastrocnemius muscle weight were conducted and morphology of the regenerated nerves were studied with image analysis. Results: At 6 months postoperatively, the nerve conduction velocity recovered to 60.86% and 54.36% (P>0.05), and the gastrocnemius muscle weight recovered to 50.89% and 46.11% (P>0.05) in the Control group and the PTFE group respectively. At 9 months postoperatively, the recovery rate was 65.99% and 58.79% for NCV (P>0.05), and 52.56% and 47.89% for gastrocnemius muscle weight (P>0.05) in the Control group and the PTFE group respectively. Regenerated nerve fibers in the PTFE group had a regular round shape with no fragmentation, wrinkling or splitting of the myelin sheath. Image analysis revealed that the ratio of the myelin area to the total fiber area was larger at 9 months than at 6 months in both groups (P<0.01). Conclusions: Microporous PTFE conduit may be an alternative for nerve repair allowing of guided nerve regeneration and functional recovery with no obvious adverse effect at long-term.

    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.

    Stereotactic linear accelerator-based radiosurgery (LINAC-RS) is increasingly used for microsurgically inaccessible or recurrent pituitary adenomas. This single-center study evaluates the long-term follow-up after LINAC-RS of nonsecreting pituitary adenomas (NSA). Patients and methods: Between 1992 and August 2008, 65 patients with NSA were treated. Patient treatment and follow-up were conducted according to a prospective protocol. Indications for LINAC-RS were (1) tumor recurrence or (2) residual tumor. Three patients were treated primarily. For analysis of prognostic factors, patients were grouped according to epidemiological or treatment-associated characteristics. Results: A total of 61 patients with a follow-up {>=} 12 months (median 83 months, range 15-186 months, longest follow-up of published radiosurgery series) were evaluated with regard to their clinical, radiological, and endocrinological course. The median tumor volume was 3.5 ml ({+-} 4.3 ml, range 0.3-17.3 ml) treated with a median surface and maximum dose of 13.0 Gy and 29.7 Gy, respectively. Local tumor control was achieved in 98%. One patient died of unrelated cause after 36 months and 1 patient developed a radiation-induced seizure disorder. Visual complications did not occur. In 37 of 41 patients (90.2%), pituitary function remained stable. Maximum dose to the pituitary {<=} 16 Gy and female gender were positive prognostic factors for the preservation of pituitary function. Conclusion: LINAC-RS is a minimally invasive, safe, and effective treatment for recurrent NSA or microsurgically inaccessible residual tumor. LINAC-RS yielded a high rate of local long-term tumor control with a small number of radiation-induced side effects. (orig.)

    As no long-term results of a blind opening up of the pulmonary valve either by balloon valvoplasty or closed Brock valvotomy have been published, we examined the outcome of 12 patients with valvar pulmonary stenosis 17 +/- 5 (11-22) years after surgery. The Brock valvotomy had been carried out at a mean age of 3 +/- 2.8 (0.2-8.5) years. The mean pressure gradient across the right ventricular outflow tract had been 116 +/- 45 (75-97) mmHg at the catheter study or 106 +/- 43 (40-160) mmHg as measured intraoperatively. The right ventricular pressure after the Brock procedure was measured in the operating room in five patients as 46 +/- 15 (30-60) mmHg. Seven patients had been recatheterized at a mean age of 9.5 +/- 2 (7-12.7) years; at that time the gradient across the pulmonary valve had been 20 +/- 14 (10-37) mmHg. At a mean age of 21.7 +/- 3 (15-26) years these and five further patients were reexamined by echo Doppler. This time the pressure gradient across the pulmonary valve was 13 +/- 6 (7-20) mmHg. Moderate pulmonary incompetence was present in four and mild incompetence in eight patients; two had mild tricuspid insufficiency. All except one patient, who had suffered a cerebrovascular accident before surgery, were in NYHA functional class 1 and pursuing a profession. From these data we conclude that the blind opening-up of the pulmonary valve achieves excellent long-term palliation.

    Background First-line treatment for patients with superficial femoral arterial (SFA) occlusive disease has yet to be determined. This study compared long-term outcomes between primary SFA stent placement and primary femoral-popliteal bypass. Periprocedural patient factors were examined to determine their effect on these results. Methods All femoral-popliteal bypasses and SFA interventions performed in consecutive patients with symptoms Rutherford 3 to 6 between 2001 and 2008 were reviewed. Time-dependent outcomes were analyzed using the Kaplan-Meier method and log-rank test. Cox proportional hazards were performed to determine predictors of graft patency. Multivariate analysis was completed to identify patient covariates most often associated with the primary therapy. Results A total of 152 limbs in 141 patients (66% male; mean age, 66 ± 22 years) underwent femoral-popliteal bypass, and 233 limbs in 204 patients (49% male; mean age, 70 ± 11 years) underwent SFA interventions. Four-year primary, primary-assisted, and secondary patency rates were 69%, 78%, and 83%, respectively, for bypass patients and 66%, 91%, and 95%, respectively, for SFA interventions. Six-year limb salvage was 80% for bypass vs 92% for stenting (P = .04). Critical limb ischemia (CLI) and renal insufficiency were predictors of bypass failure. Claudication was a predictor of success for SFA stenting. Three-year limb salvage rates for CLI patients undergoing surgery and SFA stenting were 83%. Amputation-free survival at 3 years for CLI patients was 55% for bypass and 59% for SFA interventions. Multivariate predictors (odds ratios and 95% confidence intervals) of covariates most frequently associated with first-line SFA stenting were TransAtlantic Inter-Society Consensus II A and B lesions (5.9 [3.4-9.1], P 70 years (2.1 [1.4-3.1], Ppatients were more likely to have nondiabetic status (5.6 [3.3-9.4], P patient-specific covariates, and anatomic lesion classification have significant association

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

    Purpose: To evaluate the technical success rate, procedure-related complications, and clinical long-term results for patients who underwent infrapopliteal angioplasty. Materials and Methods: We retrospectively evaluated all patients who underwent infrapopliteal angioplasty to treat critical chronic limb ischemia or severe claudication from 1/1997 to 12/1999. We excluded patients with acute (< 2 weeks) limb ischemia. Procedure-related data were prospectively documented in a database and analyzed with a focus on the technical success rate and procedure-related complications. In addition all clinical documents were analyzed, and a follow-up examination was performed or telephone interviews were conducted with patients, relatives and referring doctors for follow-up. The primary end points were the limb salvage rate and patient survival rate. The secondary end points included the complication rate, technical success rate, and walking distance. Results: 112 patients with a mean age of 72 years (41 women, 71 men) underwent crural angioplasty on 121 limbs. Four patients suffered from severe claudication (Rutherford category 3) and all others had critical chronic limb ischemia (category 4 to 6). The complication rate was 2.7 %. The technical success rate was 92 %. The ankle brachial index increased from 0.59 to 0.88. The mean walking distance increased significantly from 52 {+-} 66 to 284 {+-} 346 meters at the time of follow-up. The limb salvage rate was 83.6 % after one year and 81.1 % after three years. The mean survival rate according to Kaplan-Meier was 79.4 %, 69.2 %, and 54.2 % at 1, 2, and 3 years, respectively. Patients with at least one patent run-off vessel after angioplasty had a significantly better limb salvage rate. Diabetes was not a risk factor for limb salvage. Conclusion: Infrapopliteal angioplasty shows a high technical success rate with an acceptable complication rate. The clinical long-term success seems favorable if a least one open run-off vessel was

    Full Text Available Objective: to evaluate the efficiency of arthroscopic lavage in combination with subsequent injection of hyaluronic acid into the joint cavity at shortand long-term follow-ups. Subjects and methods. Eighty-two patients with knee osteoarthrosis (OA were examined in accordance with the American College of Rheumatology criteria. Group 1 consisted of 40 patients only after arthroscopic lavage; Group 2 comprised 42 patients who were administered hyaluronic acid after arthroscopic lavage. Clinical evaluation encompassed pain while walking, resting, and moving (by a visual analogue scale, limited ability in covering 100 m (by a 5-point scale, general clinical evaluation (by a 5-point ordinal scale, the presence or absence of pain after 100-m walking, as well as resting pain (its presence or absence. Results. The treatment effect evaluated using different indicators was comparably positive in both groups within 3 months. Following 3 months of therapy, its effect remained stable and even better in Group 2. The latter showed a particularly noticeable superiority a year later. Thus, there were excellent and good results in 88 and 47.5% in Groups 2 and 1, respectively. The clinical symptoms of the disease were absent in 58% in Group 2 and in only 15% in Group 1. Moreover, Group 1 showed worsening and 20% of the patients had no effect. This trend was also seen while evaluating the therapeutic effectiveness in different periods. Thus, after therapy, no substantial difference was found in both groups, but 3 months later this difference was as many as 0.8 scores and a year later Group 2 had many points in its favor (1.2 scores. Conclusion. Arthroscopic lavage followed by the administration of hyaluronic acid makes it possible to prevent the negative effect of a washing liquid on the metabolism and structure of the articular cartilage and to achieve a long-term effect against the major clinical symptoms (joint pain and function affecting the quality of life.

    The current study was conducted to evaluate the long-term clinical and radiological outcomes after arthroscopic arthrolysis for arthrofibrosis after anterior cruciate ligament reconstruction (ACLR). All patients treated with arthrolysis between 1990 and 1998 were included. Indication was arthrofibrosis in at least one knee compartment or a cyclops syndrome limiting range of motion (ROM) by > 5° of extension deficit and 15° of flexion deficit. International Knee Documentation Committee (IKDC) 2000 subjective and objective, Lysholm score, and x-ray evaluation were documented. Statistical analysis and power calculation were performed (P < .05). One hundred forty-one patients (follow-up, 71%) were examined at a mean of 18.7 ± 2.6 years after arthroscopic arthrolysis. Mean IKDC 2000 score was 79.49 ± 14.32. IKDC objective was normal in 0%, nearly normal in 6%, abnormal in 56%, and severely abnormal in 38%. One hundred percent of patients showed more than grade II osteoarthritis. ROM improvement after arthrolysis did not change significantly compared with midterm results (t = 4.5 years). Patients with persisting motion deficits (P = .02) and after medial meniscus resection (P < .001) at time of ACLR showed significantly greater progression of osteoarthritis in comparison with patients without these additional disorders. In case of arthrolysis later than 1 year after ACLR, a more severe osteoarthritis grade (4% vs 20% grade III; P = .038) and a lower jump distance (IKDC: 61% A, 25% B vs 39% A, 41% B; P = .028) were obvious compared with patients who underwent arthrolysis within the first year after ACLR. Long-term motion improvement can be achieved by arthrolysis. Persistent loss of motion resulted in a higher degree of osteoarthritis in the study population. Early intervention seems advisable as patients with arthrolysis later than 1 year after index surgery reached worse IKDC objective grading. Level IV, therapeutic case series. Copyright © 2016

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

    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

    The Thrust Plate Prosthesis is a femoral implant designed for total hip arthroplasty, based on the principles of physiologic loading of the metaphysis of the proximal femur, and preserving the bone stock. This study presents the long-term clinical and radiological results of 34 patients with 36 Thrust Plate Prostheses. In a retrospective analysis, we investigated the reoperation-free survival as well as the clinical and radiological results. Mean age at operation was 51 +/- 6.4 years. Mean follow-up length was 11.9 +/- 1.6 years. Reoperation-free survival was 88.9%. Four (11.1%) reoperations were performed, in three patients due to aseptic loosening and in one patient because of a fracture distal to the lateral plate. Three of the reoperations were performed between 12 and 32 months postoperatively. The major complaint was pain at the lateral side of the hip (44%). Radiolucencies did not exceed 1 mm, but 35% of the hips showed resorption of the cortex directly under the thrust plate, together with cancellous bone hypertrophy at the calcar, noted in 97%. Because of the relatively high reoperation-free survival and favourable radiological results, the Thrust Plate Prosthesis appears as a possible alternative to stemmed total hip arthroplasty, especially in relatively young patients.

    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

    The authors analyzed the long-term results and radiological aspects of sphenoorbital meningioma (with emphasis on exophthalmos) in a series of 30 patients who underwent resection. Data obtained in all 30 patients who underwent surgery for typical sphenoorbital meningioma at the authors' institution between June 1994 and September 2005 were analyzed retrospectively. The exophthalmos index (EI) was measured on preoperative MR images and/or CT scans and compared between the early and last follow-up examinations. All patients were women 35-74 years of age (median 51 years). Exophthalmos was the presenting symptom in 28 patients (93%), and was observed on preoperative MR images in all patients. The median duration of symptoms before surgery was 10 months (2-120 months). Total resection (Simpson Grade I) was not achieved in these patients because of the impossibility of resecting the dura mater in the superior orbital fissure without causing significant complications. Subtotal resection (Simpson Grade II) was obtained in 90% of patients, and in 3 patients (10%) a portion of the tumor was deliberately left in place because of extensive macroscopic infiltration of the cavernous sinus and/or extraocular muscles (Simpson Grade III). No patient died. Radiological evaluation at a median follow-up of 61 months (range 17-136 months) showed no contrast enhancement in 14 patients (47%), residual contrast enhancement without evolution in 13 (43%), and recurrence (new contrast enhancement) in 3 (10%). The EI was improved at the first radiological follow-up (median 12 months) in 27 patients (90%), and at the last radiological follow-up (median 61 months) in 28 patients (93%). In the interval between the first and final imaging follow-up, the EI improved in only 8 patients (20%), worsened in 15 patients (50%), and showed no variation in 7 patients (30%). Sphenoorbital meningiomas are insidious tumors with slow progression. Even when exophthalmos is not clinically evident, it is always

    Full Text Available 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.

    Intersphincteric resection has been performed as an alternative to abdominoperineal resection for low rectal cancer. The purpose of this study was to assess the long-term results after intersphincteric resection in terms of the morbidity, oncologic safety, and defecatory function. Between 1994 and 2006, 107 consecutive patients with low rectal cancer had curative intersphincteric resection, categorized as total, subtotal, or partial resection of the internal anal sphincter. There were no mortalities. Neorectal mucosal prolapse in patients with total intersphincteric resection and coloanal anastomotic stenosis in patients with subtotal or partial intersphincteric resection were observed as characteristic late complications. The five-year disease-free survival rates classified according to the TNM stage were 100 percent for stage I, 83.5 percent for stage II, and 72.0 percent for stage III cases. The five-year cumulative local recurrence rate after intersphincteric resection was 2.5 percent. Defecatory function, which was evaluated by bowel movement in a 24-hour period, and continence after intersphincteric resection were objectively good. The results of the multivariate analysis revealed that age was the only factor associated with a risk of fecal incontinence. Provided strict selection criteria are used, intersphincteric resection may be the optimal sphincter-preserving surgery for low rectal cancer.

    Full Text Available Six individuals with Ullrich congenital muscular dystrophy (UCMD and mutations in the genes-encoding collagen VI, aging 5–9, received 3–5 mg/kg of cyclosporine A (CsA daily for 1 to 3.2 years. The primary outcome measure was the muscle strength evaluated with a myometer and expressed as megalimbs. The megalimbs score showed significant improvement (P=0.01 in 5 of the 6 patients. Motor function did not change. Respiratory function deteriorated in all. CsA treatment corrected mitochondrial dysfunction, increased muscle regeneration, and decreased the number of apoptotic nuclei. Results from this study demonstrate that long-term treatment with CsA ameliorates performance in the limbs, but not in the respiratory muscles of UCMD patients, and that it is well tolerated. These results suggest considering a trial of CsA or nonimmunosuppressive cyclosporins, that retains the PTP-desensitizing properties of CsA, as early as possible in UCMD patients when diaphragm is less compromised.

    Strontium ranelate 2 g/day has proven efficacy against vertebral and nonvertebral fracture over 5 years in postmenopausal osteoporosis, though many women require longer-term treatment. This article describes the efficacy, safety, and tolerability of this agent over 8 years. Postmenopausal osteoporotic women having participated in the 5-year efficacy trials SOTI and TROPOS were invited to enter a 3-year open-label extension study. The results presented here focus on patients who received strontium ranelate for 8 years. At the extension baseline, the population treated for 8 years (n=879; 79.1+/-5.6 years) had femoral neck T-score of -2.61+/-0.71. The cumulative incidences of new vertebral and nonvertebral fractures (13.7% and 12.0%, respectively) over years 6 to 8 were non-statistically different from the cumulative incidences in the first 3 years of the original studies (11.5% and 9.6%). Lumbar spine, femoral neck, and total hip bone mineral density (BMD) increased throughout the 8-year period. Annual relative change in BMD was significant at every visit, except the 8-year visit for femoral neck and total hip BMD. Strontium ranelate was safe and well tolerated over 8 years. Long-term treatment with strontium ranelate 2 g/day in postmenopausal osteoporotic women leads to continued increases in BMD at all sites. The data also provide some evidence for a sustained antifracture efficacy.

    Sleeve gastrectomy (SG) is one of the surgical procedures applied for treating morbid obesity consisting of removing the gastric fundus and transforming the stomach into a narrow gastric tube. The aim of this experimental study is to create a functional model of SG and to present the long-term weight loss results. Twenty adult Wistar rats were fed with high fat diet for 12 weeks before being divided randomly in two groups of ten rats each. One group underwent SG performed with the use of staples, and the other group underwent a sham operation (control group). The animals' weight was evaluated weekly for 15 weeks after the operation. All animals survived throughout the experiment. After the operation both groups started to lose weight with maximum weight loss on the seventh postoperative day (POD) for the sham-operated group and on the 15th POD for the SG group. Thereafter, both groups started to regain weight but with different rates. By the fourth postoperative week (POW), the average weight of the sham group did not differ statistically significantly compared to the preoperative weight, while after the eighth POW, rats' average weight was statistically significantly increased compared to the preoperative value. On the other hand, average weight of the SG group was lower postoperatively until the end of the study compared to the preoperative average weight. We have created a surgical rat model of experimental SG model, enabling the further study of biochemical and hormonal parameters.

    Full Text Available Abstract Background Memokath urethral sphincter stents are used to facilitate bladder emptying in patients with spinal cord injury, but long term follow-up has not been reported. Methods Case series of ten men with spinal cord injury who underwent insertion of Memokath stents and were followed for up to nine years. Results Within four years, the stent had to be removed in nine out of ten patients because of: extensive mucosal proliferation causing obstruction to the lumen of the stent; stone around the proximal end of the stent, incomplete bladder emptying, and recurrent urinary infections; migration of the stent into the bladder related to digital evacuation of bowels; large residual urine; concretions within the stent causing obstruction to flow of urine, and partial blockage of the stent causing frequent episodes of autonomic dysreflexia. In one patient the stent continued to function satisfactorily after nine years. Conclusions The Memokath stent has a role as a temporary measure for treatment of detrusor-sphincter dyssynergia in selected SCI patients who do not get recurrent urinary infection and do not require manual evacuation of bowels.

    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.

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.

    Ninety-six consecutive above-knee femoropopliteal bypasses, using polytetrafluoroethylene (PTFE) preferentially, were performed for limb-threatening ischaemia. Cumulative primary graft patency was 68 per cent, 49 per cent and 36 per cent and limb salvage 93 per cent, 85 per cent and 75 per cent at 1, 3 and 5 yr respectively. As a result of poor long term survival (51 per cent at 5 yr), and the healing of remedial lesions before graft occlusion, 68 patients (72 per cent) required no further intervention. Eighteen secondary bypasses were undertaken, 12 using ipsilateral saphenous vein. In this group of elderly patients with poor life expectancy, where a limited operation is desirable, the use of PTFE provided excellent limb salvage with low morbidity. Although we can no longer justify our continued use of PTFE in every case of critical ischaemia because of its inferior patency to autogenous vein, we continue to use it preferentially in patients whose lifespan is likely to be short and in cases where a remedial lesion is present.

    AIM: To assess the effectiveness of minimally invasive versus traditional open surgical approach in the treatment of Zenker diverticulum.METHODS: Between 1976 and 2006, 297 patients underwent transoral stapling (n = 181) or stapled diverticulectomy and cricopharyngeal myotomy (n = 116). Subjective and objective evaluations of the outcome of the two procedures were made at 1 and 6 mo after operation, and then every year. Long-term follow-up data were available for a subgroup of patients at a minimum of 5 and 10 years.RESULTS: The operative time and hospital stay were markedly reduced in patients undergoing the endosurgical approach. Overall, 92% of patients undergoing the endosurgical approach and 94% of those undergoing the open approach were symptom-free or were significantly improved after a median follow-up of 27 and 48 mo, respectively. At a minimum follow-up of 5 and 10 years, most patients were asymptomatic after both procedures, except for those individuals undergoing an endosurgical procedure for a small diverticulum (< 3cm).CONCLUSION: Both operations relieve the outflow obstruction at the pharyngoesophageal junction,indicating that cricopharyngeal myotomy has an important therapeutic role in this disease independent of the resection of the pouch and of the surgical approach.Diverticula smaller than 3 cm represent a formal contraindication to the endosurgical approach because the common wall is too short to accommodate one cartridge of staples and to allow complete division of the sphincter.

    Three chemical tracer experiments and one extended injection of fluid low in concentration of dissolved species have been carried out during the Long Term Flow Test (LTFT) of the Fenton Hill Hot Dry Rock (HDR) reservoir. The tracer tests,results illustrate the dynamic nature of the flow system, with more fluid traveling through longer residence time paths as heat is extracted. The total fracture volumes calculated from these tests allow us to determine the fate of unrecovered injection fluid, examine the pressure-dependence of fracture volume, and, through a comparison to the hydraulic performance, postulate a model for the nature of the pressure drops through the system. The Fresh Water Flush (FWF) test showed that while no dissolved specie behavior is truly conservative (no sources or sinks), several breakthrough curves are well explained with a pore fluid displacement model. Other dissolved components are clearly influenced by dissolution or precipitation reactions. Finally, the transient response of the chemistry during the FWF to an increase in production well pressure showed that some fractures connected to the production well preferentially open when pressure is raised.

    We wanted to evaluate the long-term results of a dual expandable nitinol stent for the palliative treatment of malignant gastroduodenal strictures. The dual stent consists of two stents; an outer partially nylon covered stent and an inner bare nitinol stent. The outer stent was placed into the stricture and this was followed by coaxial placement of the inner bare stent. Using fluoroscopic guidance, dual expandable stents were placed in 86 patients with inoperable malignant gastroduodenal strictures. The technical and clinical success, the complication, survival and the stent patency were evaluated during the follow-up period. Stent placement was technically successful in 83 of the 86 patients. After stent placement, 74 of the 85 patients showed improvement of their symptoms. During the mean follow-up period of 133 days, 24 patients (28%) developed recurrent symptoms due to incomplete expansion (n=1), stent migration (n=4), food impaction (n=2), granulation tissue formation (n=2), tumor overgrowth (n=6), tumor ingrowth (n=1) and stent collapse (n=8). Eleven of them were successfully treated by means of placing a second stent. The median period of stent patency was 212 days (mean, 299 days). The 30-day, 60-day, 90-day and 180-day patency rates were 93%, 84%, 81% and 53%, respectively. The dual expandable nitinol stent seems to be effective for the palliation of malignant gastroduodenal strictures

    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.

    Objective: The aim of the present study is to determine long-term clinical efficacy of uterine fibroid embolization (UFE) for symptomatic fibroids in conjunction with MR evaluation. Materials and methods: Sixteen patients with a follow-up period of 4 years or longer were analyzed retrospectively. Ages ranged from 27 to 45 (mean 39.5) years. Mean follow-up periods were 5.8 years (range: 4.1-6.9 years). The symptom changes, in terms of menorrhagia and dysmenorrhea and bulk-related symptoms, were assessed. The primary embolic agent was polyvinyl alcohol particle (250-710 {mu}m). All patients underwent preprocedural and long-term follow up MR imaging. Uterine volumes were calculated using MRI. Results: Symptom improvements were reported for menorrhagia (8/9, 88.9%), dysmenorrhea (5/5, 100%), and bulk-related symptoms (7/9, 77.8%) at long-term follow up. Two patients (12.5%) had symptom recurrences at long-term follow-up. Tumor regrowth from incomplete infarction was a cause of recurrence in one patient and newly developed leiomyomas in the other one. One patient underwent hysterectomy because endometriosis developed 4 years after UFE. Of the 14 necrotic myomas on short-term follow up MR after UFE, eight (57.1%) demonstrated maintaining necrosis with further shrinkage and six (42.9%) were no longer visualized on long-term follow up MR images. Overall, the mean volume reduction rates of the predominant fibroid and uterus were 80.5%, 36.7% at long-term follow up, respectively. Conclusion: UFE is an effective treatment for symptomatic fibroids with an acceptable long-term success rate. Long-term MR imaging after UFE revealed persistent necrotic fibroid, non-visualization of fibroids and tumor regrowth when incompletely infarcted.

    Full Text Available This study was to define preoperative predictors from radiologic findings for the pathologic risk groups based on long-term surgical outcomes, in the aim to help guide individualized patient management.We retrospectively reviewed 321 consecutive patients with clinical stage IA lung adenocarcinoma with ground glass component on computed tomography (CT scanning. Pathologic diagnosis for resection specimens was based on the 2011 IASLC/ATS/ERS classification of lung adenocarcinoma. Patients were classified into different pathologic risk grading groups based on their lymph node status, local regional recurrence and overall survival. Radiologic characteristics of the pulmonary nodules were re-evaluated by reconstructed three-dimension CT (3D-CT. Univariate and multivariate analysis identifies independent radiologic predictors from tumor diameter, total volume (TV, average CT value (AVG, and solid-to-tumor (S/T ratio. Receiver operating characteristic curves (ROC studies were carried out to determine the cutoff value(s for the predictor(s. Univariate cox regression model was used to determine the clinical significance of the above findings.A total of 321 patients with clinical stage IA lung adenocarcinoma with ground glass components were included in our study. Patients were classified into two pathologic low- and high- risk groups based on their distinguished surgical outcomes. A total of 134 patients fell into the low-risk group. Univariate and multivariate analyses identified AVG (HR: 32.210, 95% CI: 3.020-79.689, P<0.001 and S/T ratio (HR: 12.212, 95% CI: 5.441-27.408, P<0.001 as independent predictors for pathologic risk grading.

    Previous research has identified long-term exposure to stress as a risk factor for negative mental and physical health outcomes. This pattern of findings suggests that environmental stimuli that evoke feelings of stress or strain may also result in physiological responses, which may accumulate over the life course and ultimately increase the overall risk of various physical health conditions. This physiological "wear and tear" resulting from sustained levels of stress or strain has been previously operationalized as allostatic load (AL), a comprehensive indicator of stress exposure. The current study examines the association between one potential environmental stressor-perceived inequality-and AL with a research design aimed at addressing both observed and unobserved sources of confounding; it also employs a more comprehensive AL measure (comprised of 24 biomarkers tapping seven physiological systems) than previous studies. The biomarker twin sample from the Midlife Development in the United States (MIDUS) study was used to estimate a series of twin comparison models, which include controls for latent sources of influence that cluster within families. The sibling comparison models also included additional controls for lifestyle choices, overall physical health, and demographics which may confound the examined associations. The results revealed significant associations between greater perceptions of inequality and greater overall levels of AL. The association persisted even after including controls for both observed and unobserved influences that may confound the examined associations but was limited to more recent measures of perceived inequality. Associations involving earlier measures of perceived inequality, along with a lifetime measure, failed to reach conventional levels of significance. Perceived inequality appears to be a robust predictor of AL and potentially contributes to subsequent physical health problems, particularly for more proximate forms of

    To evaluate the long-term results after breast-conserving surgery and radiation therapy in early breast cancer in terms of failure, survival, and cosmesis. One hundred fifty-four patients with stage I and II breast cancer were treated with conservative surgery plus radiotherapy between January 1992 and December 2002 at the Keimyung University Dongsan Medical Center. According to TNM stage, 93 patients were stage I, 50 were IIa, and 11 were IIb. The affected breasts were irradiated with 6 MV photons to 50.4 Gy in 28 fractions over 5.5 weeks with a boost irradiation dose of 10{approx}16 Gy to the excision site. Chemotherapy was administered in 75 patients and hormonal therapy in 92 patients with tamoxifen. Follow-up periods were 13{approx}179 months, with a median of 92.5 months. The 5- and 10-year overall survival rates were 97.3% and 94.5%, respectively. The 5- and 10-year disease-free survival (5YDFS and 10YDFS, respectively) rates were 92.5% and 88.9%, respectively; the ultimate 5YDFS and 10YDFS rates after salvage treatment were 93.9% and 90.2%, respectively. Based on multivariate analysis, only the interval between surgery and radiation therapy ({<=}6 weeks vs. >6 weeks, p=0.017) was a statistically significant prognostic factor for DFS. The major type of treatment failure was distant failure (78.5%) and the most common distant metastatic site was the lungs. The cosmetic results were good-to-excellent in 96 patients (80.7%). Conservative surgery and radiation for early stage invasive breast cancer yielded excellent survival and cosmetic results. Radiation therapy should be started as soon as possible after breast-conserving surgery in patients with early breast cancer, ideally within 6 weeks.

    Background and Purpose: Radiotherapy (RT) is well accepted for therapy-refractory palmo-plantar eczema or psoriasis, despite of lacking evidence regarding beneficial long term effects. Furthermore, the optimal irradiation dose is unknown. We evaluated the outcome of RT with two different RT single/total dose (SD/TD) treatment policies. Patients and Methods: 28 consecutive patients with therapy-refractory eczema (n = 22) or psoriasis (n = 6) of palms and/or soles were irradiated twice a week either with a D{sub max} SD of 1 Gy (6/98-5/03; median TD: 12 Gy) or 0.5 Gy (6/03-7/04; median TD: 5 Gy). Median age was 52 years (27-71), median follow-up 20 months (4-76). Totally 88 regions were treated, 49 with 1 Gy, 39 with 0.5 Gy SD. Eight different symptoms were scored from 0 (absent) -3 (severe), giving a possible sum score of 0-24. Patients' rating of RT result was also documented (worse/stable/better/complete remission). Results: The sum score was 15 (6-23) before RT, 2 (0-16) at the end of RT, and 1 (0-21) at last follow-up, respectively. The improvement was highly significant in both treatment regimens. Better or complete remission by the patients were reported in 44 and 39 (= 83 out of 88) localisations, that was often stable during the follow-up. 5 (6%) regions in 3 (11%) patients didn't benefit from RT. Conclusion: RT reveals excellent results in palmo-plantar eczema or psoriasis. We recommend a SD of 0.5 Gy twice a week up to a TD of 4-5 Gy. (orig.)

    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.

    Highlights: • We report the long-term results (2–4 years) with Flow Diverter Devices (FDD) from a single-center. • We recommend the use of FDD for large-neck aneurysms of the ICA syphon. • We think that more sophisticate FDD will reduce the incidence of technical adverse events. - Abstract: Objectives: Flow-Diverter Devices (FDD) are a new generation stents designed for the treatment of the intracranial aneurysms. This article reports the long-term results (2–4 years) of this treatment from a single-center. Methods: From November 2008 to January 2012, 35 patients (29 females and 6 males; mean age 53.9 y) with 39 intracranial aneurysms were treated by FDD. Five patients (14.3%) had ruptured aneurysms and 30 (85.7%) had no previous hemorrhage. The procedures were performed in 5 patients (14.3%) with SILK and in 30 (85.7%) with PED. In 3 patients FDDs were used as a second treatment after failure of previous coiling (2 cases) or stenting (one case). The 39 aneurysms were in supraclinoid ICA in 26 (66.7%), cavernous ICA in 2 (5.1%), PCoA in 4 (10.2%), MCA in 5 (12.9%), SCA in 1 (2.6%) and PICA in 1 (2.6%). The aneurysms were small (<10 mm) in 32 cases (82%), large (11–25 mm) in 6 (15.3%) and giant in 1 (2.6%). The occlusion rate according to the aneurysm location, size and neck and the complications were evaluated. Results: Peri-procedural complications included transient dysarthria (2 patients), vasospasm with acute intra-stent aggregation (one), microwire rupture (one) and failure of the stent opening (one). The follow-up was made between 24 and 62 months (mean 41 months); clinical examination and CTA were performed at 1, 3, 6 and 12 months after the procedure. The complete occlusion was confirmed by CTA and DSA. MRI with angiographic-studies was taken every year. Complete occlusion was obtained in 35 aneurysms (92.1%) and subtotal in 3 (7.9%). Complete occlusion occurred at 3 months in 24 cases (68.6%), within 3 and 6 months in 9 (25.7%). The rate and

    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.

    The National Institute for Occupational Safety and Health (NIOSH) National Personal Protective Technology Laboratory (NPPTL) and the Mine Safety and Health Administration (MSHA) conduct a Long Term Field Evaluation (LTFE) program to evaluate deployed self-contained self rescuers (SCSRs). The objective of the program is to evaluate how well SCSRs endure the underground coal mining environment with regard to both physical damage and aging when they are deployed in accordance with Federal regulations (30 CFR 75.1714). This report presents findings of the combined eighth and ninth phases of the LTFE. For these phases, over four hundred SCSRs were evaluated. The units tested include the CSE SR-100, Draeger Oxy K-Plus, MSA Life-saver 60, and the OCENCO EBA 6.5. The OCENCO 20 was evaluated only in Phase 9. Testing was performed between December 2000 and April 2004. Results of the evaluation indicate that all SCSRs experience some performance degradation due to the mining environment. Observed degradation varies from elevated levels of carbon dioxide, high breathing resistance, and reduced capacity. Mechanical degradation to the SCSR components included breathing hoses, chemical beds, outer cases and seals. The LTFE tests discussed in this report are different from tests performed for SCSR certification to the requirements of 42 Code of Federal Regulations, Part 84 (42 CFR, Part 84). LTFE tests reported here are conducted to an end point, oxygen depletion, to enable comparison of the duration of new and deployed SCSRs. The method for obtaining deployed SCSRs for this evaluation was not a random selection from the deployed population of SCSRs. Although the results of these tests are useful for observing performance of the tested SCSRs, they are not representative of all deployed SCSRs. 9 refs., 10 figs., 9 tabs., 3 apps.

    OBJECTIVE Supplementary motor area (SMA) epilepsy is a well-known clinical condition; however, long-term surgical outcome reports are scarce and correspond to small series or isolated case reports. The aim of this study is to present the surgical results of SMA epilepsy patients treated at 2 reference centers in Mexico City. METHODS For this retrospective descriptive study (1999-2014), 52 patients underwent lesionectomy and/or corticectomy of the SMA that was guided by electrocorticography (ECoG). The clinical, neurophysiological, neuroimaging, and pathological findings are described. The Engel scale was used to classify surgical outcome. Descriptive statistics, Student t-test, and Friedman, Kruskal-Wallis, and chi-square tests were used. RESULTS Of these 52 patients, the mean age at epilepsy onset was 26.3 years, and the mean preoperative seizure frequency was 14 seizures per month. Etiologies included low-grade tumors in 28 (53.8%) patients, cortical dysplasia in 17 (32.7%) patients, and cavernomas in 7 (13.5%) patients. At a mean follow-up of 5.7 years (range 1-10 years), 32 patients (61%) were classified as Engel Class I, 16 patients (31%) were classified as Engel Class II, and 4 (8%) patients were classified as Engel Class III. Overall seizure reduction was significant (p = 0.001). The absence of early postsurgical seizures and lesional etiology were associated with the outcome of Engel Class I (p = 0.05). Twenty-six (50%) patients had complications in the immediate postoperative period, all of which resolved completely with no residual neurological deficits. CONCLUSIONS Surgery for SMA epilepsy guided by ECoG using a multidisciplinary and multimodality approach is a safe, feasible procedure that shows good seizure control, moderate morbidity, and no mortality.

    The aim of this study was to evaluate the long-term results of total synovectomy in pigmented villonodular synovitis of the knee (PVNS). Open total synovectomy was performed for 19 patients (9 men, 10 women; mean age: 42.8 years) with PVNS. Of these patients, 15 had diffuse and 4 localized PVNS. The patients were followed for an average of 80.2 months and the average time between the onset of complaints and surgery was 23 months. In 4 patients, PVNS was identified during total knee replacement (TKR) performed due to gonarthrosis. Radiotherapy was performed as an adjuvant treatment in one patient with recurrence. Puncture was performed in 11 patients due to effusion and 8 to 70 cc of fluid was aspirated. Diagnosis was made during the exposure for TKR in 4 patients, by a biopsy in 2 and based on joint puncture and MRI findings in the rest. Recurrence occurred in 5 patients. A second total synovectomy was performed in 4 patients. Radiotherapy was used for the remaining one patient. Two patients were operated three times. During the follow-up, TKR was performed in 7 of the 19 patients. None of the patients developed infection and hemarthrosis requiring puncture nor required amputation or arthrodesis. Three patients had a postoperative knee joint stiffness of 10 to 25 degrees. The patients were evaluated according to the Knee Society Score and 8 (42.2%) had perfect, 9 (47.3%) good and 2 (10.5%) bad results. PVNS is a disease with a high risk of recurrence. No individual or combined treatment method can offer a definitive solution. Open or arthroscopic radical synovectomy is still considered as the gold standard. If necessary, adjuvant intraarticular or extraarticular radiotherapy can be added to the treatment.

Systemic and local (fracture hematoma cytokine levels (IL-6, -8, -10 and alarmins (HMGB1, HSP70 were measured via ELISA.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.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.

    Excellent treatment results are obtained for stage I testicular seminoma treated with orchiectomy and prophylactic radiotherapy. In patients with stage I nonseminomatous testicular tumors, surveillance alone is successful, however, this treatment option for stage I testicular seminomas is controversial. There have been few reports of long-term follow-up of surveillance alone for patients with stage I testicular seminoma. To assess the appropriateness of this treatment option, a retrospective survey of stage I testicular seminoma was undertaken. Twenty-seven patients who underwent prophylactic radiation therapy (RT group) and 41 patients followed only by surveillance (S group) after high orchiectomy were evaluated. Their follow-up consisted of frequent clinical examinations, abdominal CT scans, chest x-rays and serum tumor markers. In the RT group, with a median follow-up period of 15 years, 1 patient (3.6%) had a recurrence in the lung at 4 months after orchiectomy and died, but the remaining 26 are alive with no evidence of disease (NED). In the S group, with a median follow-up period of 7.3 years, 5 (12.2%) relapsed in the retroperitoneal lymph nodes, but all are alive with NED following chemotherapy. The remaining 36 are all alive without recurrence (follow-up period, 38 to 132 months). Although the relapse rate in the S group was relatively higher than in the RT group, there was no significant difference between the 2 groups. If a frequent follow-up protocol is administered and followed by the patient, surveillance alone may be a recommended management for stage I testicular seminoma. (author)

    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.

    We addressed the long-term results of the Medtronic Mosaic porcine prosthesis in the aortic position. From 1994 to 2004, 1007 Mosaic valves were used for aortic valve replacement. The data were prospectively collected, retrospectively analyzed, and stratified according to patient age at surgery (group 1, 80 years), using both actual (cumulative risks) and actuarial methods. Operative mortality was 5% (valve related in 14%). Globally, 8122.17 patient-years were available (average follow-up, 8.5 ± 3.9 years; 99.8% complete). Overall, survival at 15 years was lower among the elderly strata (P < .0001). Freedom from structural valve deterioration (SVD) was 95.1% (actual) and 86.3% (actuarial; 24 SVD events). Survival free from SVD was lower in group 1 (P = .003) but comparable among the other groups. Overall freedom at 15 years from the composite endpoint (any valve-related adverse events) was 82% (actual) and 71.3% (actuarial). No meaningful intergroup differences were found in survival free from the composite endpoint (P = .9) or freedom from valve-related mortality (P = .8). Younger patients at surgery did not show accelerated degeneration. No relationship could be established between prosthetic size and SVD. The implantation of a bioprosthesis in patients aged 70 years or older remains fully justified. The rate of SVD was higher in younger patients, mainly owing to their greater life expectancy. Patients younger than 70 can receive a bioprosthesis, provided that the correct information regarding the expected durability has been provided. This might be better accomplished through the actual methodology. Copyright © 2014 The American Association for Thoracic Surgery. Published by Mosby, Inc. All rights reserved.

    Surgical treatment of forearm deformities in patients with multiple cartilaginous exostoses remains controversial. The purpose of the present study was to determine the reasonable indications for operative treatment and to evaluate long-term results of forearm surgery in these patients. We retrospectively reviewed twenty-three patients (thirty-one forearms) after a mean duration of follow-up of nearly thirteen years. The mean age at the time of the initial procedure was eleven years. The patients underwent a variety of surgical procedures, including excision of exostoses; corrective procedures (lengthening of the radius or ulna and/or corrective osteotomy of the radius and/or ulna) and open reduction or excision of a dislocated radial head. Clinical evaluation involved the assessment of pain, activities of daily living, the cosmetic outcome, and the ranges of motion of the wrist, forearm, and elbow. The radiographic parameters that were assessed were ulnar variance, the radial articular angle, and carpal slip. Four patients had mild pain, and five patients had mild restriction of daily activities at the time of follow-up. Eight patients stated that the appearance of the forearm was unsatisfactory. Radiographic parameters (ulnar variance, radial articular angle, carpal slip) were initially improved; however, at the time of the final follow-up visit, the deformities had again progressed and showed no significant improvement. The only procedure that was associated with complications was ulnar lengthening. Complications included nonunion (three forearms), fracture of callus at the site of lengthening (two forearms), and temporary radial nerve paresis following an ulnar distraction osteotomy (one forearm). Excision of exostoses significantly improved the range of pronation (p = 0.036). In our patients with multiple cartilaginous exostoses, corrective osteotomy and/or lengthening of forearm bones was not beneficial. The most beneficial procedure was excision of exostoses

    No single procedure for high anal fistula delivers a high cure rate while also completely protecting sphincter function. This paper reports our long-term results with the cutting seton for high fistulae and draws comparisons with advancement flap and ligation of intersphincteric fistula track (LIFT) procedures. A retrospective study of prospectively collected data in consecutive patients undergoing treatment with cutting seton for high cryptoglandular fistulae was carried out. A strict protocol dictated tightening intervals of at least 4 weeks and no muscle division. In 59 patients (male : female = 39:20) followed-up at mean 9.4 years (range 1.7-15.6 years) healing rates, continence (St Mark's score 0-24), patient-perceived overall change in bowel control (-5 to +5), faecal incontinence quality of life (FIQL) and overall patient satisfaction (visual analogue score 0-10) were assessed. Primary and secondary healing rates were 93% and 98%. Mean continence score was 4.1, significantly worse in women than men (median 6, range 0-22 versus median 1, range 0-17; P = 0.006). Seventy-eight per cent of patients had normal continence or minor incontinence (score 0-6), 13.5% moderate incontinence (score 7-12) and 8.5% severe incontinence (score >12). Sixty-three per cent of patients had no change or improved patient-perceived overall bowel control. Mean FIQL scores were high and significantly correlated with continence. Median satisfaction score was 9. Cutting seton for high anal fistula achieved healing in 98% with good continence in the majority, particularly in males, and a high level of patient satisfaction. Multicentre prospective studies are needed to adequately compare cutting seton, flap and LIFT procedures. © 2015 Royal Australasian College of Surgeons.

    Purpose: to prospectively evaluate the short- and long-term efficacy of external radiotherapy (RT) in patients with age-related macular degeneration (AMD) by comparing two different dose schedules. Patients and methods: in this prospective, nonrandomized, comparative study including 80 patients, the efficacy of external RT with a total dose of 14.4 Gy (group A, n = 40) and 25.2 Gy (group B, n = 40) was compared. Patients of group a were irradiated between September 1995 and July 1996, patients of group b between August 1996 and November 1997. 67 patients presented with occult choroidal neovascularization (CNV), 13 with classic subfoveal lesions. Complete ophthalmologic investigation was performed before RT, at intervals of 3 months during the 1st year after RT, and of 6 months thereafter. Results: 12 months after RT, vision deteriorated in 85% (14.4 Gy) and 65% (25.2 Gy) of patients. Central visual field decreased with both dose schedules. There was no morphological benefit in neovascular changes. After 48 months, complete follow-up was possible in 46 patients who showed a significant loss of vision similar to the natural course of AMD. Conclusion: external RT of AMD with 14.4 Gy as well as with the escalated dose of 25.2 Gy showed a poor beneficial outcome after 6 and 12 months, respectively. After a follow-up of 4 years, visual outcome in irradiated patients was similar to the natural course of the disease. A conspicuous efficacy of RT in prevention of blindness could not be demonstrated. (orig.)

    To evaluate the long-term efficacy of pain reduction by two dose-fractionation schedules for radiotherapy of painful shoulder syndrome. Between February 2006 and February 2010, 312 evaluable patients were recruited for this prospective trial. All patients received low-dose orthovoltage radiotherapy. One course consisted of 6 fractions in 3 weeks. In the case of insufficient pain remission after 6 weeks, a second course was administered. Patients were randomly assigned to one of two groups to receive single doses of either 0.5 or 1.0 Gy. Endpoint was pain reduction. Pain was measured before radiotherapy, as well as immediately after (early response), 6 weeks after (delayed response) and approximately 3 years after (long-term response) completion of radiotherapy using a questionnaire-based visual analogue scale (VAS) and a comprehensive pain score (CPS). Median follow-up was 35 months (range 11-57). The overall early, delayed and long-term response rates for all patients were 83, 85 and 82%, respectively. The mean VAS scores before treatment and those for early, delayed and long-term response in the 0.5- and 1.0-Gy groups were 56.8±23.7 and 53.2±21.8 (p=0.16); 38.2±36.1 and 34.0±24.5 (p=0.19); 33.0±27.2 and 23.7±22.7 (p=0.04) and 27.9±25.8 and 32.1±26.9 (p=0.25), respectively. The mean CPS values before treatment and those for early, delayed and long-term response were 9.7±3.0 and 9.5±2.7 (p=0.31); 6.1±3.6 and 5.4±3.6 (p=0.10); 5.3±3.7 and 4.1±3.7 (p=0.05) and 4.0±3.9 and 5.3±4.4 (p=0.05), respectively. No significant differences in the quality of the long-term response were found between the 0.5- and 1.0-Gy arms (p=0.28). Radiotherapy is an effective treatment for the management of benign painful shoulder syndrome. For radiation protection reasons, the dose for a radiotherapy series should not exceed 3.0 Gy. (orig.)

    A surgically treated material comprising 18 patinets with heart failure from aortic insufficiency during acute endocarditis has been reviewed. At the time of operation the mean duration of heart failure was 3 weeks and duration of endocarditis 9 weeks. Blood culture was positive in half of the patients, 39% had predisposing valve disease, 14 (78%) had a preoperative heart catheterization. The peroperatively measured regurgitation averaged 55%. All 18 patients had an artifical valve implanted, and the mean observation time for 13 long-term survivors was 3 1/3 years. There were 3 postoperative and 2 late deaths. A long-term survival rate of 73% strongly supports early surgical treatment in patients with aortic insufficiency and heart failure during acute endocarditis.

There were a total of 121 total knee joint replacements in the set with 107 patients aged 71.3 years on average (52-86 years. A total of 115 knees diagnosed with osteoarthritis of the 3-4th degree were indicated for the surgery, and there were 6 patients with the diagnosis of rheumatoid arthritis. Functional outcomes were evaluated using the Knee Society Score (KSS, Results. The assessment of the knee state on a scale KSS average clinical section KSS (knee score was 48.2, and functional (function score - 46,8 points. After surgery, the indices increased to 87.4 points and 85.8 points, respectively. One complication was described during the surgery, namely - the fracture of the medial tibia condyle (0.8%. In the early post-surgery period, peroneal nerve paresis was observed in two patients (1.6%. In the postoperative period, disorders of the wound healing were observed in 6 patients (4.9%, which were healed successfully in a conservative way. In the late post-surgery period, there were infectious complications in the knee joint in 4 knee joints (3.3%. Aseptic loosening was observed in 4 cases out of 117 endoprostheses (3.4%. It always concerned the loosening of tibial component. The loosening of the femoral component was not observed. In the period from the implantation until June 2014, which is 16-22 years after the implantation, there are 16 patients in total surviving, who had a total of 21 implanted endoprostheses. Among them there are no signs of a loosening only in 4 patients (19%; there was an apparent radiolucent line up until 2 mm with a sclerotic rim under the tibial component.

Conclusion: Challenging cases of ACL tears with large chondral defects treated with concurrent ACL reconstruction and ACI can lead to moderately improved pain and function at long-term follow-up. Factors associated with clinical failure are not clear. When combined with ACI, patients undergoing revision ACL reconstructions have worse function preoperatively compared with those undergoing primary reconstructions but have similar final outcomes.

    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

    For recovery to be deemed adequate, the laryngectomized patient requires restoration of both the ability to swallow and to speak. Immediate results and long-term functional recovery after pharyngoesophageal (PE) reconstruction with the radial forearm free flap were studied in 22 consecutive patients who had undergone primary (n = 3) or secondary (n = 19) reconstructions after total laryngectomy. Circumferential reconstructions were done in 13 patients (mean length 10 cm, range 6 to 16) and patch reconstructions in 9 patients (defect size range 4 x 4 cm to 8 x 7 cm). Flap leakage was evaluated for all patients, and postoperative diet and ability to swallow were evaluated for 16 patients with an intact tongue base. Voice was evaluated for 6 patients with circumferential reconstructions who had later undergone tracheoesophageal puncture with placement of a Blom-Singer voice prosthesis, and the results compared with those of a control group of 5 voice-restored patients who had undergone laryngectomy with primary closure of the pharyngoesophagus. All 22 flaps survived and none of the patients died. Although 7 (32%) reconstructions leaked, all but 1 closed spontaneously. Fourteen (88%) of the patients with an intact tongue base have no dysphagia and are on a regular diet, and 2 remain on an oral liquid diet. Compared with controls, patients with a radial free-flap reconstruction had similar loudness with soft speech (43 dB for controls versus 52 dB for radial patients) and loud speech (61 dB versus 63 dB), comparable fundamental frequencies (136 Hz versus 125 Hz), and increased jitter (2% versus 5%). Speech intelligibility was judged by untrained listeners as excellent for 4 of the patients with radial flaps and good for the other 2. The radial free flap offers the advantages of rapid harvest, high flap reliability, and minimal donor-site and patient morbidity. Leakage rate and deglutition restoration were similar to those of other reconstructions, including the free

    To evaluate the activity, safety and long-term survival of patients after preoperative oxaliplatin and 5-fluorouracil chemoradiation therapy in locally advanced rectal cancer (LARC). Patients with resectable, T3-4 and/or nodal involvement rectal adenocarcinoma were treated with oxaliplatin 60 mg/m(2) weekly and 5-fluorouracil 200 mg/m(2)/d infused continuously for five days, over a period of five weeks, and radiotherapy (45 Gy/25 fractions). The primary end-point was pathological complete response (ypCR). Safety, overall survival (OS) and relapse-free survival (RFS) were secondary end-points. Sixty-six patients were treated. Grade 1-2 diarrhea was the most common adverse event. The ypCR rate was 16.7% (95% confidence interval=7.7-25.7%). After a median follow-up of 73.5 months, 23 patients (34.8%) had experienced relapse. Five-year actuarial RFS and OS rates were 64% and 73%, respectively. Five-year actuarial RFS was 91.7% in the ypCR group versus 57.8% in non-ypCR cases. Long-term local control and survival after this very well-tolerated regimen appear encouraging.

    Background Endovascular therapy is a treatment option for localized occlusion of the subclavian artery. In this report the long-term experience with 59 patients is presented.Methods Between June 1998 and September 2008, we used endovascular therapy to treat 61 subclavian arterial obstructive lesions in 59 patients (46 males and 13 females, 34-82 years of age with a mean age (61.9±11.0) years). Twenty patients (34%) had clinical symptoms due to vertebrobasilar insufficiency, 26 (44%) had disabling arm ischemia, and 13 (22%) had both symptoms. We performed all procedures under local anesthesia. The approaches were from the femoral artery (n=47), brachial artery (n=\\, involving bilateral subclavian disease) or both (n=11). Sixty stents were implanted. All patients were followed-up at 1,3, 6, and 12 months post-procedure, and annually thereafter. Results We achieved technical success in 58 (95.1%) arteries, all of which were stented. There were three technical failures; two were due to the inability to cross over an occlusion, necessitating the switch to an axillo-axillary bypass, and the third was due to shock after digital subtraction angiography and prior to stenting. Arterial stenosis pre- and post-stenting was (83.6±10.8)% and (2.5±12.5)% (P <0.01). Clinical success was achieved in 55 of the 59 patients (93.4%). Of the four clinical failures, three were technical and the remaining patient had a stent thrombosis. Systolic blood pressure difference between the two brachial arteries was (44.7±18.5) vs. (2.2±3.9) mmHg (P <0.01). Primary patency was 98% at 12 months, 93% at 24 months, and 82% at 5 years. Five patients were lost to follow-up by 12 months post-stenting. Significant recurrent obstruction developed in five patients with resumption of clinical symptoms. The overall survival rate was 98.2% at 12 months, 89.5% at 24 months, and 84.5% at 5 years.Conclusions Endovascular therapy for proximal subclavian arterial obstructive lesions is effective and

    To analyze the treatment outcomes, complications, prognostic factors after a long-term follow-up of patients with nasopharyngeal carcinoma treated with radiation therapy (RT) alone or concurrent chemoradiation therapy (CCRT). Between December 1981 and December 2006, 190 eligible patients with non-metastatic nasopharyngeal carcinoma were treated at our department with a curative intent. Of these patients, 103 were treated with RT alone and 87 patients received CCRT. The median age was 49 years (range, 8-78 years). The distributions of clinical stage according to the AJCC 6th edition included I: 7 (3.6%), IIA: 8 (4.2%), IIB: 33 (17.4%), III: 82 (43.2%), IVA: 31 (16.3%), IVB: 29 (15.3%). The accumulated radiation doses to the primary tumor ranged from 66.6-87.0 Gy (median, 72 Gy). Treatment outcomes and prognostic factors were retrospectively analyzed. Acute and late toxicities were assessed using the RTOG criteria. A total of 96.8% (184/190) of patients completed the planned treatment. With a mean follow-up of 73 months (range, 2-278 months; median, 52 months), 93 (48.9%) patients had relapses that were local 44 (23.2%), nodal 13 (6.8%), or distant 49 (25.8%). The 5- and 10-year overall survival (OS), disease-free survival (DFS), and disease-specific survival (DSS) rates were 55.6% and 44.5%, 54.8% and 51.3%, in addition to 65.3% and 57.4%, respectively. Multivariate analyses revealed that CCRT, age, gender, and stage were significant prognostic factors for OS. The CCRT and gender were independent prognostic factors for both DFS and DSS. There was no grade 4 or 5 acute toxicity, but grade 3 mucositis and hematologic toxicity were present in 42 patients (22.1%) and 18 patients (9.5%), respectively. During follow-up, grade 3 hearing loss in 9 patients and trismus in 6 patients were reported. The results of our study were in accordance with findings of previous studies and we confirmed that CCRT, low stage, female gender, and young age were related to improvement in OS

From September 1997 to March 2000, paralytic lagophthalmos due to leprosy in 92 patients were corrected with TMT. The 89 cases (127 to eyes including 51 unilateral and 38 bilateral) followed up 3 years after operation were analyzed. There were 69 males and 20 females with ages ranging from 18 to 65 years (52 years on average). The duration of lagophthalmos was 1-22 years with an average of 8.2 years. And 36 eyes were complicated with lower eyelid ectropion. Sixty-five eyes were corrected with Johnson's procedure (Johnson's TMT group), 62 with the modified TMT procedure (modified TMT group). The modifications were as follows: (1) omitting the fascial strip in the lower eyelid to avoid postoperative ectropion. (2) fixing the fascial strip of the upper eyelid to the middle or inner margin of the tarsal palate depending on the degree of the lagophthalmos to avoid possible ptosis of the upper eyelid. In Johnson's TMT group, the mean lid gap on light closure was reduced to 3.1 mm postoperatively from 7.7 mm preoperatively; and the mean lid gap on tight closure was reduced to 0.5 mm postoperatively from 6.1 mm preoperatively. The symptoms of redness (73.7%) and tearing (63.7%) disappeared or were improved postoperatively. However, ectropion and ptosis occurred in 24 eyes and 9 eyes respectively. The overall excellent and good rate was 58.5%. In the modified TMT group, the mean lid gap on light closure was reduced to 3.3 mm postoperatively from 7.5 mm preoperatively; and the mean lid gap on tight closure was reduced to 0. 6 mm postoperatively from 6. 3 mm preoperatively. The symptoms of redness (90.9%) and tearing (71.0%) disappeared or were improved postoperatively, and no ectropion or ptosis was found except one ectropion. The overall excellent and good rate was 87.1%, which was significantly

    ABSTRACT Soils play a key role in the Earth System (Keesstra et al., 2012; Brevick et al., 2015). Soils are a key resource for the human societies (Mol and Keesstra, 2012) and they are relevant to achieve the sustainability such as the United Nations Goals highlight (Keesstra et al., 2016). Agriculture soils, especially those under conventional tillage, are prone to organic matter mineralization, soil erosion, compaction and increase of greenhouse gases emission (Novara et al., 2011; Bruun et al., 2015; de Moraes et al., 2015; Choudhury et al., 2016; del Mar et al., 2016). The adoption of organic farming and sustainable management practices may provide a sustainable crop productivity, and in the meanwhile mitigate the negative impact of agriculture on ecosystem services benefits (Laudicina et al., 2015; Parras-Alcantara et al., 2015; 2016). The aim of this study was to examine, under field conditions, the long-term changes of soil organic matter under organic farming management in citrus orchards in Mediterranean environment and evaluate the ecosystem service on C sequestration in terms of economic benefits. The research was carried out at the Alcoleja Experimental Station located in the Cànyoles river watershed in the Eastern Spain on 45year old citrus plantation. Soil Organic Matter (SOM) content was monitored for 20 years at 6 different soil depth. The profitability of citrus plantation was estimated under conventional and organic management. Results showed that SOM in the 0-30 cm soil depth was the double after 20 years of organic farming management, ranging from 0.8 g kg-1 in 1995 to 1.5 g kg-1 in 2006. The highest SOM increase was in the top soil layer (368% of SOM increase in comparison to the initial SOM content) and decreased with soil depth. The effect of organic farming was relevant after 5 years since land management change, indicating that in Mediterranean environment the duration of long term studies should be higher than five years and proper policy

    Diabetes mellitus (DM) is coupled to the risk and symptomatic onset of pancreatic ductal adenocarcinoma (PDAC). The important question whether DM influences the prognosis of resected PDAC has not been systematically evaluated in the literature. We therefore performed a systematic review and meta-analysis evaluating the impact of preoperative DM on survival after curative surgery. The databases Medline, Embase, Web of Science, and the Cochrane Library were searched for studies reporting on the impact of preoperative DM on survival after PDAC resection. Hazard ratios and 95 % confidence intervals (CI) were extracted. The meta-analysis was calculated using the random-effects model. The data search identified 4,365 abstracts that were screened for relevant articles. Ten retrospective studies with a cumulative sample size of 4,471 patients were included in the qualitative review. The mean prevalence of preoperative DM was 26.7 % (1,067 patients), and all types of pancreatic resections were considered. The meta-analysis included 8 studies and demonstrated that preoperative DM is associated with a worse overall survival after curative resection of PDAC (hazard ratio 1.32, 95 % CI 1.46-1.60, P = 0.004). Only 2 studies reported separate data for new-onset and long-standing DM. To our knowledge, this is the first meta-analysis evaluating long-term survival after PDAC resection in normoglycemic and diabetic patients, demonstrating a significantly worse outcome in the latter group. The mechanism behind this observation and the question whether different antidiabetic medications or early control of DM can improve survival in PDAC should be evaluated in further studies.

    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). 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. 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. 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.

    A retrospective study of 149 patients with rectal cancer diagnosed between 1972 and 1979 was undertaken to compare survival, disease-free survival, recurrence sites, and long-term complications of 40 patients who received 4000 to 4500 rads of preoperative adjuvant radiotherapy (radiation group) with those of 109 patients treated by resection alone (control group). After a mean follow-up of 84 months and 99 months, respectively, survival of the irradiated patients was significantly better than that of controls (68% versus 52%, p less than 0.05). Disease-free survival of those patients rendered free of disease by treatment was also superior for the irradiated group (84% versus 57%, p less than 0.005). Local recurrence without signs of distant metastases developed only one-third as often in irradiated patients (6% versus 18%). Distant metastases, alone or in combination with local recurrence, were also less common after radiation (12% versus 27%). Second primary tumors developed in 15% and 10% of the respective groups, a difference that was not statistically significant. When we consider the survival benefit of preoperative radiation therapy, long-term complications were relatively mild. Delayed healing of the perineum was noted in two irradiated patients. Persistent diarrhea was severe enough to warrant treatment in only one case, and one patient required a colostomy for intestinal obstruction from pelvic fibrosis.

  20. Cholinergic pairing with visual activation results in long-term enhancement of visual evoked potentials.

    Full Text Available Acetylcholine (ACh contributes to learning processes by modulating cortical plasticity in terms of intensity of neuronal activity and selectivity properties of cortical neurons. However, it is not known if ACh induces long term effects within the primary visual cortex (V1 that could sustain visual learning mechanisms. In the present study we analyzed visual evoked potentials (VEPs in V1 of rats during a 4-8 h period after coupling visual stimulation to an intracortical injection of ACh analog carbachol or stimulation of basal forebrain. To clarify the action of ACh on VEP activity in V1, we individually pre-injected muscarinic (scopolamine, nicotinic (mecamylamine, alpha7 (methyllycaconitine, and NMDA (CPP receptor antagonists before carbachol infusion. Stimulation of the cholinergic system paired with visual stimulation significantly increased VEP amplitude (56% during a 6 h period. Pre-treatment with scopolamine, mecamylamine and CPP completely abolished this long-term enhancement, while alpha7 inhibition induced an instant increase of VEP amplitude. This suggests a role of ACh in facilitating visual stimuli responsiveness through mechanisms comparable to LTP which involve nicotinic and muscarinic receptors with an interaction of NMDA transmission in the visual cortex.

    The Latarjet procedure is effective in managing anterior glenohumeral instability in the short term, but there is concern for postoperative arthritis. The purpose of this study was to evaluate the long-term functional outcome after the Latarjet procedure and to assess the prevalence of and risk factors for glenohumeral arthritis after this procedure. A retrospective review was conducted of 68 Latarjet procedures at a mean of 20 years postoperatively. The mean age at surgery was 29.4 years. Functional outcome was determined by the Rowe score, subjective shoulder value, and recurrence of instability. Preoperative arthritis and postoperative radiographs were reviewed to evaluate the development or progression of arthritis. The mean Rowe score increased from 37.9 preoperatively to 89.6 at final follow-up (P Latarjet procedure provides excellent long-term outcomes in the treatment of recurrent anterior glenohumeral instability. Twenty years after the Latarjet procedure, arthritis may develop or progress in 23.5% of cases, but the majority of arthritis is mild.

    The key for a scientific understanding of natural environments and the determination of baselines is the long-term monitoring of environmental factors. For seafloor environments including gas hydrate systems, cabled ocean observatories are important platforms for the remote acquisition of a comprehensive suite of datasets. This is particularly critical for those datasets that are difficult to acquire with autonomous, battery-powered systems, such as cameras or high-bandwidth sonar because cable connections provide continuous power and communication from shore to the seafloor. Ocean Networks Canada is operating the NEPTUNE cabled undersea observatory in the Northeast Pacific with two nodes at gas hydrate sites, Barkley Canyon and Clayoquot Slope. With up to seven years of continuous data from these locations we are now beginning to understand the dynamics of the natural systems and are able to classify the variations within the gas hydrate system. For example, the long-term monitoring of gas vent activity has allowed us to classify phases of low, intermittent and high activity that seem to reoccur periodically. Or, by recording the speeds of bacterial mat growth or detecting periods of increased productivity of flora and fauna at hydrates sites we can start to classify benthic activity and relate that to outside environmental parameters. This will eventually allow us to do enhanced environmental monitoring, establish baselines, and potentially detect anthropogenic variations or events for example during gas hydrate production.

    The Bernese periacetabular osteotomy is a commonly used non-arthroplasty option to treat developmental hip dysplasia in symptomatic younger patients. Predicting which hips will remain preserved and which hips will go on to require arthroplasty following periacetabular osteotomy is a major challenge. In the present study, we assessed the intermediate to long-term results following periacetabular osteotomy to demonstrate the clinical outcomes for patients with varying amounts of dysplasia and arthritis. From these results, a probability-of-failure analysis was conducted to predict the likelihood of hip preservation and to improve surgical decision-making. Of the 189 hips (in 157 patients) that were treated with periacetabular osteotomy by a single surgeon from May 1991 to September 1998, thirty-one had diagnoses other than developmental hip dysplasia and twenty-three were lost to follow-up. The remaining 135 hips (in 109 patients) were retrospectively reviewed at an average of nine years. Hips were evaluated with use of the pain subscale of the Western Ontario and McMaster Universities Osteoarthritis Index postoperatively as well as with radiographs that were made preoperatively and at one and more than five years postoperatively. Osteotomy failure was defined as a pain score of >or=10 or the need for total hip arthroplasty. One hundred and two hips (76%) remained preserved at an average of nine years, with an average Western Ontario and McMaster Universities pain score of 2.4 of 20. Thirty-three hips (24%) met the failure criteria: seventeen underwent arthroplasty at an average of 6.1 years after the osteotomy, and sixteen had a postoperative pain score of >or=10. Kaplan-Meier analysis with arthroplasty as the end point revealed a survival rate of 96% (95% confidence interval, 93% to 99%) at five years and 84% (95% confidence interval, 77% to 90%) at ten years. Complications occurred in twenty hips. Fifteen hips (11%) were treated with a subsequent arthroscopy

    The aim of this study was to evaluate the long-term efficacy of two dose-fractionation schedules for radiotherapy of achillodynia. Between February 2006 and February 2010, 112 evaluable patients were recruited for this prospective trial. All patients received orthovoltage radiotherapy. One course consisted of 6 fractions/3 weeks. In the case of insufficient remission of pain after 6 weeks, a second series was performed. Patients were randomly assigned to receive either single doses of 0.5 or 1.0 Gy. The endpoint was pain reduction. Pain was measured before, right after (early response), 6 weeks after (delayed response), and approximately 2 years after radiotherapy (long-term response) with a questionnaire-based visual analogue scale (VAS) and a comprehensive pain score (CPS). The median follow-up was 24 months (range, 11-56). The overall early, delayed, and long-term response rates for all patients were 84 %, 88 %, and 95 %, respectively. The mean VAS values before treatment for early, delayed, and long-term responses for the 0.5-Gy and 1.0-Gy groups were 55.7 ± 21.0 and 58.2 ± 23.5 (p = 0.53), 38.0 ± 23.2 and 30.4 ± 22.6 (p = 0.08), 35.5 ± 25.9 and 30.9 ± 25.4 (p = 0.52), and 11.2 ± 16.4 and 15.3 ± 18.9 (p = 0.16), respectively. The mean CPS values before treatment for early, delayed, and long-term responses were 8.2 ± 3.0 and 8.9 ± 3.3 (p = 0.24), 5.6 ± 3.1 and 5.4 ± 3.3 (p = 0.76), 4.4 ± 2.6 and 5.3 ± 3.8 (p = 0.58), and 2.2 ± 2.9 and 2.8 ± 3.3 (p = 0.51), respectively. No significant differences in long-term response quality between the two arms was found (p = 0.73). Radiotherapy is a very effective treatment for the management of benign achillodynia. For radiation protection, the dose for a radiotherapy series should not exceed 3.0 Gy. (orig.)

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

    To report the long-term outcome of corneal collagen cross-linking (CXL) for progressive keratoconus in pediatric patients. "Epithelium-off" CXL was performed in pediatric eyes with progressive keratoconus. Spectacle-corrected distance visual acuity (CDVA), retinoscopy, topography, and tomography were documented preoperatively and postoperatively at 3 months, 6 months, 1 year, and annually thereafter. A total of 377 eyes of 336 pediatric patients aged 8 to 18 years with progressive keratoconus underwent CXL. Of these, 194 eyes had a follow-up beyond 2 years and up to 6.7 years. At last follow-up, there was significant improvement in mean CDVA from 0.33 ± 0.22 to 0.27 ± 0.19 logMAR (P ≤ 0.0001), reduction in mean topographic astigmatism from 7.22 ± 3.55 to 6.13 ± 3.28 D (P = 0.0001), mean flattening of 1.20 ± 3.55 diopters in maximum keratometry (Kmax) (P = 0.0002), and mean corneal thinning of 31.1 ± 36.0 μm (P keratoconus (average keratometry 48-53 diopters). Central cones showed more corneal flattening than peripheral cones. Stabilization or flattening of Kmax was seen in 85% of eyes at 2 years and in 76% after 4 years. Stabilization or improvement of CDVA was seen in 80.1% of eyes at 2 years and in 69.1% after 4 years. CXL remains effective in stabilizing keratoconus for longer than 2 years in a majority of pediatric eyes. Flattening of Kmax was greater in moderately advanced keratoconus and central cones. Long-term follow-up beyond 4 years, however, revealed that a few eyes showed features suggestive of reversal of the effect of CXL.

    In-situ split (ISS) liver resection is a novel method to induce rapid hypertrophy of the contralateral liver lobe in patients at risk for postoperative liver failure due to insufficient liver remnant. So far, no data about oncological long-term survival after ISS liver resection is available. We retrospectively analyzed our patients treated with ISS liver resection at the Department of Surgery of the University of Regensburg, the first center worldwide to perform ISS. Between 2007 and 2014, ISS liver resection was performed in 16 patients. Two patients (12.5 %) were lost in early postoperative phase (90 days) and one was lost to follow-up. Thirteen patients with a follow-up period of more than 3 months were included into oncologically focused analyses. Median follow-up was 26.4 months (range 3.2-54.6). Seven patients had suffered from colorectal liver metastases (CRLM) and six from various other liver malignancies (non-CRLM). The ISS procedure had led to a median increase of 86.3 % of the left lateral liver lobe after a median of 9 days (range 4-28 days). Median disease-free survival (DFS) was 14.6 months and median overall survival (OS) was 41.7 months (26.4 months when including 90-days mortality). Three-year survival was calculated with 56.4 and 48.9 % when including perioperative mortality, respectively (CRLM 64.3 % vs. non-CRLM 50 %). ISS liver resection can provide long-term survival of selected patients with advanced liver malignancies that otherwise are not eligible for liver resection due to insufficient liver remnant.

    This study was designed to evaluate long-term outcome in locally advanced resectable extraperitoneal rectal cancer treated by preoperative radiochemotherapy. Eighty-three consecutive patients who developed locally advanced resectable extraperitoneal rectal cancer underwent preoperative concomitant radiochemotherapy followed by surgery, including total mesorectal excision. Median follow-up was 108 (range, 10-169) months. The living patients underwent complete follow-up of, at least, nine years. Fourteen patients developed local recurrence. The time to detection was longer than two years in eight cases and longer than five years in four. Twenty-one patients developed metastases, 19 within the first five years from surgery. At the univariate analysis, clinical stage at presentation, lymph node involvement at clinical restaging after neoadjuvant therapy, and pT and pN stage were found positively correlated to the incidence of metastases. At the multivariate analysis, the only factors which confirmed a positive correlation were pT stage and pN stage. The actuarial overall survival at five, seven, and ten years was 75.5, 67.8, and 60.4 percent, respectively. The same figures for cancer-related survival were 77.9, 70, and 65.8 percent. At the univariate analysis, factors directly correlated with worse survival were: TNM stage at clinical restaging after neoadjuvant therapy (in particular lymph node involvement) pTNM, pT, and pN. At the multivariate analysis the only factors that confirmed a correlation with worse survival were pTNM, pT, and pN. Long- term follow-up allows to individuate 28 percent of all local relapses after the first five years from surgery. Postoperative stage is highly predictive of prognosis.

    Adequate documentation of the outcome of treatment of pigmented villonodular synovitis (PVNS) is sparse. Available case series show relatively short follow-up times and often combine locations or subtypes to increase patient numbers. This article describes the long-term follow-up of a single institution's large consecutive series of PVNS. Retrospectively, 107 PVNS patients were identified between 1985 and 2011 by searching pathology and radiology records. Treatment complications, recurrences and quality of life were evaluated. Most patients (85.2%) were primarily or secondarily treated at our institution. Both subtypes, localized PVNS [29 (27%)] and diffuse PVNS [75 (70%)] were represented. The knee was affected in 88% of patients. Treatments received were surgery, external beam radiotherapy, radiosynovectomy, targeted therapy, immunotherapy or combinations of these. Forty-nine (46%) patients had prior treatment elsewhere. The mean follow-up from diagnosis until last contact was 7.0 years (range 0.3-27.4) for localized PVNS and 14.5 years (range 1.1-48.7) for diffuse PVNS. The 1- and 5-year recurrence-free survival rates for diffuse PVNS were 69% and 32%, respectively. Quality of life, estimated by 36-item Short Form Health Survey (SF-36) scores, were not significantly different between localized and diffuse PVNS. However, both patient groups scored lower than the general population norms on the general health component (59.2 and 56.3, respectively, P PVNS increase with time. Long-term follow-up shows, particularly in diffuse PVNS, it is a continually recurring problem, and over time it becomes increasingly difficult to cure. The quality of life is decreased in patients with PVNS compared with the general population. © The Author 2014. Published by Oxford University Press on behalf of the British Society for Rheumatology.

    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). 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(3). The median maximum and marginal doses were 28 Gy and 14 Gy, respectively. 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. 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 treated with GKS when necessary. Copyright © 2013

    The goal of this work was to evaluate the long-term efficacy of two dose-fractionation schedules for radiotherapy of calcaneodynia. Between February 2006 and February 2010, 457 evaluable patients were recruited for this prospective trial. All patients received orthovoltage radiotherapy. One course consisted of 6 fractions/3 weeks. In case of insufficient remission of pain after 6 weeks a second series was performed. Patients were randomly assigned to receive either single doses of 0.5 or 1.0 Gy. Endpoint was pain reduction. Pain was measured before, right after (early response), 6 weeks (delayed response), and approximately 2.5 years after radiotherapy (long-term response) with a questionnaire-based visual analogue scale (VAS) and a comprehensive pain score (CPS). The median follow-up was 32 months (range 9-57 months). The overall early, delayed, and long-term response rates for all patients were 87, 88, and 95 %. The mean VAS values before treatment, for early, delayed, and long-term response for the 0.5 and 1.0 Gy groups were 65.5 ± 22.1 and 64.0 ± 20.5 (p = 0.19), 34.8 ± 24.7 and 39.0 ± 26.3 (p = 0.12), 25.1 ± 26.8 and 28.9 ± 26.8 (p = 0.16), and 16.3 ± 24.3 and 14.1 ± 19.7 (p = 0.68). The mean CPS values before treatment, for early, delayed, and log-term response were 10.1 ± 2.7 and 10.0 ± 3.0 (p = 0.78), 5.6 ± 3.7 and 6.0 ± 3.9 (p = 0.34), 4.0 ± 4.1 and 4.3 ± 3.6 (p = 0.26), and 2.1 ± 3.3 and 2.3 ± 3.2 (p = 0.34), respectively. No significant differences in long-term response quality between the two arms were found (p = 0.50). Radiotherapy is a very effective treatment for the management of benign calcaneodynia. For radiation protection reasons, the dose for a RT series should not exceed 3.0 Gy. (orig.)

    Full Text Available Animals that experience adverse events in early life often have life-long changes to their physiology and behavior. Long-term effects of stress during early life have been studied extensively, but less attention has been given to the consequences of negative experiences solely during the adolescent phase. Adolescence is a particularly sensitive period of life when regulation of the glucocorticoid stress hormone response matures and specific regions in the brain undergo considerable change. Aversive experiences during this time might, therefore, be expected to generate long-term consequences for the adult phenotype. Here we investigated the long-term effects of exposure to chronic unpredictable stress during adolescence on adult decision making, coping response, cognitive bias, and exploratory behavior in rats. Rats exposed to chronic unpredictable stress (e.g. isolation, crowding, cage tilt were compared to control animals that were maintained in standard, predictable conditions throughout development. Unpredictable stress during adolescence resulted in a suite of long-term behavioral and cognitive changes including a negative cognitive bias (F1,12 = 5.000, P < 0.05, altered coping response (T1,14 = 2.216, P = 0.04, and accelerated decision making (T1,14 = 3.245, P = 0.01. Exposure to chronic stress during adolescence also caused a short-term increase in boldness behaviors; in a novel object test 15 days after the last stressor, animals exposed to chronic unpredictable stress had decreased latencies to leave a familiar shelter and approach a novel object (T1,14 = 2.240, P = 0.04; T1,14 = 2.419, P = 0.03, respectively. The results showed that stress during adolescence has long-term impacts on behavior and cognition that affect the interpretation of ambiguous stimuli, behavioral response to adverse events, and how animals make decisions. Stress during adolescence also induced short-term changes in the way animals moved around a novel environment.

    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.

    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 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 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).

    Transsphenoidal surgery (TSS) is the treatment of choice for Cushing's disease (CD). However, the best treatment option when hypercortisolism persists or recurs remains unknown. The aim of this study was to analyze the short and long-term outcome of repeat TSS in this situation and to search for response predictors. Data from 26 patients with persistent (n=11) or recurrent (n=15) hypercortisolism who underwent repeat surgery by a single neurosurgeon between 1982 and 2009 were retrospectively analyzed. Remission was defined as normalization of urinary free cortisol (UFC) levels, and recurrence as presence of elevated UFC levels after having achieved remission. The following potential outcome predictors were analyzed: adrenal status (persistence or recurrence) after initial TSS, tumor identification in imaging tests, degree of hypercortisolism before repeat TSS, same/different surgeon in both TSS, and time to repeat surgery. Immediate postoperative remission was achieved in 12 patients (46.2%). Five of the 10 patients with available follow-up data relapsed after surgery (median time to recurrence, 13 months). New hormone deficiencies were seen in seven patients (37%), and two patients had cerebrospinal fluid leakage. No other major complications occurred. None of the preoperative factors analyzed was predictive of surgical outcome. When compared to initial surgery, repeat TSS for CD is associated to a lower remission rate and a higher risk of recurrence and complications. Further studies are needed to define outcome predictors.

    The late outcome in 226 patients who survived surgical repair of aortic coarctation was assessed 15-30 years after operation. Twenty six patients died during the follow up mainly from causes related to surgical repair or to associated cardiovascular anomalies. The survival rates of patients operated on between the ages of four and 20 years are 97%, 97%, 92% at 10, 20, and 30 years after operation. For patients operated on after the age of 20 the corresponding rates are 93%, 85%, and 68%. This difference is statistically significant from the fifteenth year of follow up onwards. The survival of patients operated on before the age of 20 is not significantly different from that of a comparable general Italian population. Recoarctation occurred in only 8% of patients who had end to end anastomosis, whereas it occurred in 35% of those who had other types of operation. Two thirds of the patients were hypertensive at the last visit. The actuarial curve shows that blood pressure was normal in most patients 5-10 years after operation, but 30 years after coarctation repair only 32% of patients are expected to be normotensive. Thus early repair of aortic coarctation appears to improve long term survival. Intervention in older patients and when blood pressure is high seem to be the most important predictors of late hypertension. PMID:3593616

  19. Nissen fundoplication for gastro-oesophageal reflux disease: long-term results.

    Since its introduction by Rudolph Nissen in 1956, fundoplication has become the most commonly used antireflux procedure. Following fundoplication the majority (80 to 90%) of the patients become symptomfree or have only mild and occasional reflux symptoms in the long run. With a short and loose fundic wrap postoperative dysphagia is not a clinical problem, providing that preoperative manometry shows adequate peristalsis. Flatus is increased after fundoplication, but rarely to a disturbing extent. Patients who have problems with flatus preoperatively are also prone to have complaints postoperatively. Bloating is decreased rather than increased after fundoplication. At endoscopy as intact seen fundic wrap (the main determinant of the long-term outcome) is observed in 70% to 80% of the cases 10 to 20 years after the operation. Oesophageal 24-hour pH-recording is normal and oesophagitis cured in similar number of patients. In conclusion, Nissen fundoplication gives effective cure of symptoms of gastro-oesophageal reflux disease and reliably corrects reflux oesophagitis. Postoperative adverse effects are rare and well tolerable and do not detract from the success of the operation in correctly selected patients.

    Femoral revision total hip arthroplasty may be a complex procedure due to extensive periprosthetic bone loss. Fluted, tapered stems provide secure axial and rotational stability in the distal femur. We retrospectively evaluated the long-term outcome of the cementless Wagner Self-Locking prosthesis (Sulzer Orthopedics Ltd, Winterthur, Switzerland). From 1992 to 1998, 68 consecutive femoral revisions were performed in 66 patients using the Wagner tapered stem. Twenty-five patients deceased for unrelated causes without additional surgery. The studied group consisted of 41 hips in 41 patients, 12 males and 29 females, aged from 29 to 80 years (mean 61 years). Thirty-five hips (85.4%) included severe deficiency of bone stock. A transfemoral approach was carried out in 32 cases (78%). Bone grafting was never supplemented. Average follow-up was 13.9 years (range 10.4 to 15.8 years). Clinical evaluation was performed using Harris Hip Score (HHS). Osseointegration of the stem and progression of periprosthetic bone remodelling were assessed radiographically. Five stems required rerevision because of deep infection (2), progressive subsidence (2) complicated by hip instability and head-neck disassembly, and old dislocation following acetabular component failure (1). Four hips (9.7%) dislocated, and 8 stems (19.5%) subsided significantly. Average HHS improved from 33 points preoperatively to 75 points at the latest follow-up examination (p risk complications (dislocation, subsidence) should be minimized by the development of modular stems.

    We studied cardiac function, clinical outcome and quality of life (QOL) long after aortic valve replacement for pure aortic stenosis. Forty-four patients in small group [St. Jude Medical (SJM) 17 HP, 19 A], and 69 patients in non-small group (19 HP, 21 A, 23 A) operated on from 1984 to 2004 were enrolled in this study. We assessed the clinical data, aortic pressure gradient, left ventricular mass index (LVMI), and ejection fraction (EF) by preoperative and postoperative echocardiography. Moreover to evaluate QOL after the operation, we performed SF-36 used for the evaluation of health and QOL worldwide. Mean follow-up is 7.1 +/- 4.8 years in small group, and 6.8 +/- 4.6 years in non-small group. There were 2 hospital deaths in small group, and 1 in non-small group. The actual survival rate at 10-year were 89.2% in small group, and 85.6% in non-small group. There was no significant difference in hospital mortality, LVMI, long-term survival rate, and the scores of SF-36 between the 2 groups. The use of small sized prosthetic valves in patients with small aortic annulus might be justified when there is no patient-prosthesis mismatch.

    The long-term effects of two schedules of radioiodine therapy in patients with toxic multinodular goitre were evaluated. Forty-five patients (group A) were treated with low doses and 58 patients (group B) with calculated doses adjusted for thyroid weight (1.85-3.70 MBq/g) and radioactive iodine uptake. Follow-up (mean[+-]SEM) was 4.3[+-]0.2 years and 5.2[+-]0.3 years, respectively (P0.1). At the end of follow-up, hyperthyroidism was succesfully reversed in 73% (group A) and 88% (group B). In each group, hypothyroidism was present in 7%. The total dose per gram of thyroid tissue was not significantly different in groups A and B (2.1[+-]0.2 vs 2.7[+-]0.2 MBq/g). However, for patients treated with calculated doses the number of [sup 131]I administrations was significantly lower (1.3[+-]0.1) than for patients treated with low doses (2.2[+-]0.2), and the percentage of patients who were adequately treated with a single dose was more than twice as high (66% in group B versus 27% in group A). Euthyroidism was reached within a significantly shorter time after treatment with calculated doses (media time 0.6 years in group BVS 1.5 years in group A; life table analysis). It is concluded that radioiodine is an effective treatment for toxic multinodular goitre with a low risk of post-treatment hypothyroidism and that calculated (higher) doses appear to be preferable to low doses.

    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

    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.

    Full Text Available Pur po se: To evaluate the long-term visual outcome and to determine the surgical complications after cataract surgery in patients with unilateral childhood cataract. Ma te ri al and Met hod: We retrospectively reviewed the records of 18 cases with unilateral childhood cataract who had undergone cataract surgery before the age of seven. Primary intraocular lens (IOL implantation was made in children who were older than 1 year of age. Secondary IOL implantation was made after 18 months in children who were operated before the age of 1 year and were left aphakic. Occlusion therapy was performed to all children for amblyopia postoperatively. Visual acuity and complications were evaluated in a mean follow-up period of 4.8 years. Re sults: The mean age of the 18 patients (9 female/9 male at the time of surgery was 43.6±33.7(1-84 months. Eleven (61% patients had cataract surgery after 1 year of age. Secondary IOL implantation was performed at mean 28th month in 4 of 7 aphakic patients (57% who had cataract surgery before one year of age. In 3 (43% aphakic patients, secondary IOL implantation could not be performed because of ocular pathologies such as microophthalmia. Final visual acuity was 0.5 or better in 7 eyes (39%, between 0.1 and 0.5 in 6 eyes (33%, and worse than 0.1 - in 5 eyes (28%. Of 5 eyes that had visual acuity worse than 0.1, 4 (80% had at least one additional ocular pathology such as microphthalmia, strabismus and nystagmus. Nd:YAG laser posterior capsulotomy was performed at mean 8th month in 7 of 8 (87% children whose posterior capsules were left intact at surgery. Dis cus si on: Favorable visual outcomes can be achieved with surgical intervention and complementary amblyopia treatment in children with unilateral cataract. Preoperative microphthalmia, nystagmus and strabismus are not entirely an obstacle to visual development, but they are important factors leading to low visual acuity.

    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

    Serial retrospective long-term follow-up study. To assess the long-term results of anterior surgery with Cloward trephination and iliac strut grafting for cervical spondylotic myelopathy. Anterior surgery remains the most common surgical option and generally gives good results, although early and late deterioration after initial postoperative improvement has been noted. Although anterior decompression with trephination is a variant of the Cloward technique, little information is available concerning the long-term results after this procedure. One hundred sixty-eight consecutive patients treated with this technique by the same author from the years 1978 to 1992 were followed serially. One hundred and seven patients were followed for over 10 years (mean: 14.1 y) (follow-up rate: 71.8%). Clinical results were evaluated according to the Japanese Orthopedic Association system and the results at different postoperative intervals were analyzed. Thirty-six patients returned for the final follow-up. Plain radiographs were taken in neutral and flexion-extension positions and computed tomography scans were taken at fused segments and unfused levels. The mean recovery rate was 56.8% at final follow-up. Deterioration of 2 Japanese Orthopedic Association points or more was experienced in 44 patients at various postoperative periods and was more frequent at over 10 years follow-up. Kyphosis of fused segments was noted frequently on the radiographies of the 36 patients with a mean of 7.8 degrees. A straight or misaligned cervical spine was found in 28 (77.8%) patients and these deformities were more serious in multilevel fusions. Stenosis of the canal at fused segments was found in 15 (41.7%) patients owing to osteogenesis resulting from inadequate decompression or pseudoarthrosis. At unfused levels, the incidence of spondylolisthesis, bony bridge, disc hernia, and thickening or bulging of the ligament flavum was 19.4%, 27.8%, 33.3%, 19.4%, respectively, and these abnormalities

    Objectives: To evaluate the safety and long-term efficacy of computed tomography-guided percutaneous ethanol ablation for benign primary and secondary hyper functioning 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 macro nodular 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 macro nodular 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 hyper functioning adrenal disorders and is not without risks. (author)

    To review the audiologic results in a cohort of patients surgically treated for cholesteatoma. Retrospective review of patient records. Tertiary referral center. A retrospective study of patients operated on for acquired middle ear cholesteatoma during the period 1990 to 2002 was performed. A total of 758 patients were followed during a short-term period, and 611 patients were followed during a long-term period. The patients were divided into 3 age groups: children, adolescents, and adults. The localization of cholesteatoma was classified as attic, sinus, or tensa. Closed tympanoplasty was always performed as the single procedure of choice on all the children, and reoperation or conversion to open tympanoplasty was made later if needed. Adult patients were treated with single classic canal wall up, or wall down (CWD), according to the propagation of disease and condition of middle ear. Preoperative and postoperative air-bone gap (ABG) and pure-tone average were compared after short-term and long-term follow-up. Average hearing improvement (reduction of ABG) amounted 20.0 dB for short-term and deteriorated to 18.0 dB during long-term analysis for all the patients. Preoperative hearing level was significantly worse for CWD than for intact canal wall technique. The ABG closure was much better in the group with attic cholesteatoma. Both preoperative and postoperative hearing levels were worse for children than for adolescents or adults. Revision operations and bilateral cholesteatoma gave worse total postoperative hearing. The long-term results of primary operations, when recurrent cholesteatoma did not occur, were stable. Damage to auditory ossicles correlated well with total preoperative and postoperative results. The most hearing improvement was verified for the frequencies between 500 and 3,000 Hz, and there was no sensorineural hearing loss. The audiologic results of cholesteatoma surgery are preserved during long-term follow-up. We found that recurrent

    Purpose The purpose of this study was to examine the role of initial diabetes education delivery at an academic medical center (AMC) versus non-AMCs on long-term glycemic control. Methods We performed a retrospective study of children with type 1 diabetes referred to an AMC after being educated at non-AMCs. These children were matched to a group of children diagnosed and educated as inpatients at an AMC. The A1C levels at 2, 3, and 5 years from diagnosis were compared between the 2 groups of children. Results Records were identified from 138 children. Glycemic control was comparable in the non-AMC-educated versus AMC-educated patients at 2, 3, and 5 years from diagnosis. The A1C was also highly consistent in each patient over time. Conclusions Long-term glycemic control was independent of whether initial education was delivered at an AMC or non-AMC. Formal education and location at time of diagnosis do not appear to play a significant role in long-term glycemic control. Novel educational constructs, focusing on developmental stages of childhood and reeducation over time, are likely more important than education at time of diagnosis. PMID:23427241

    The aim of this chart review of adult patients treated for acute lymphoblastic leukemia (ALL) with total body irradiation (TBI) was to evaluate early and late toxicity and long-term outcome. A total of 110 adult patients (34 ± 12 years) with ALL underwent TBI (6 fractions of 2 Gy for a total of 12 Gy) as a part of the treatment regimen before transplantation. Treatment-related toxicity, mortality, and hematologic outcome are reported. Mean follow-up was 70 months. The 2- and 5-year leukemia-free survival rates were 78 and 72 %, respectively. In all, 29 % (32/110) patients suffered from medullary recurrence after a median time of 7 months. Gender was the only statistically significant prognostic factor in terms of overall survival in favor of female patients. Treatment-related mortality and overall survival after 2 and 5 years were 16 and 22 %, and 60 and 52.7 %, respectively. The most frequent late reaction wascGVHD of the skin (n = 33, 30 %). In addition, 15.5 % (17/110 patients) suffered pulmonary symptoms, and 6 patients developed lung fibrosis. Eyes were frequently affected by the radiation (31/110 = 28 %); 12 of 110 patients (11 %) presented with symptoms from osteoporosis, 5 of 110 patients (4.5 %) developed hypothyreosis and 2 patients diabetes mellitus. Of the male patients, 11 % reported erectile dysfunction or loss of libido, while 2 of 36 women reported menopausal syndrome at the mean time of 28 months after treatment with requirement for substitution. No women became pregnant after treatment. No acute or late cardiac toxicities were documented in our patients. No secondary malignancies were documented. Although hematologic outcome was in the upper range of that reported in the literature, treatment-related mortality (TRM) and medullary recurrences remain a challenge. Sophisticated radiation techniques allow for decreasing toxicity to certain organs and/or dose escalation to the bone marrow in highly selected patients in order to improve therapeutic

    The aim of this study was to determine the patency rate after femoro-popliteal stenting followed by oral clopidogrel plus long-term aspirin. In a prospective trial, 31 patients with a total of 33 femoro-popliteal artery lesions (21 stenoses, 12 occlusions; 24 femoral, 9 popliteal) were treated with flexible tantalum stents after unsuccessful percutaneous transluminal angioplasty (PTA) preceded by local fibrinolysis in 5 of 12 patients with total occlusion. Post-interventionally, oral aspirin 100 mg was started simultaneously for the long term and was combined with an oral loading dose of 300 mg clopidogrel, followed by 75 mg clopidogrel daily for 28 days. Patients were followed for at least 12 months (maximum 34 months) by clinical examination, Doppler pressure measurement, color and duplex sonography, and angiography in case of suspicion of restenosis. In a retrospective analysis, the results were compared with those of historical groups of patients having received aspirin only (41 patients) or a long-term high-dose low molecular weight heparin (LMWH)+aspirin treatment (42 patients). Three small puncture aneurysms were treated successfully by conservative means and were categorized as minor bleeding complication. Cumulative primary patency rate (PPR) was 76{+-}7.5% (1 year), and 70{+-}9.6% (2 years) in the clopidogrel+aspirin group, thus being tendentiously better than in the aspirin-only group showing 75{+-}4.6% (1 year), and 50{+-}8.1% (2 years). Long-term high-dose LMWH+aspirin treatment showed 87{+-}5.8% (1 year), and 72{+-}9.1% (2 years), thus being superior to the other treatment regimes, with a statistically significant difference (p<0.05) between the LMWH+aspirin and the aspirin group. Clopidogrel plus aspirin is a safe medication regimen and may be effective in the prevention of early stent thrombosis. Mid- and long-term patency rate seems to be intermediate as compared with other therapeutic regimens. The LMWH+aspirin seems to be superior compared with

    Follow-up examinations covered 91 patients aged from 20 to 60 years with chronic prostatitis (CP) history 1-18 years. The primary examination has found that 79.1% examinees has CP complicated with sexual dysfunction, disturbed spermatogenesis and psychoneurological disorders. In one group of CP patients etiopathogenetic treatment of CP was combined with magneto-laser-electrostimulation of the prostate provided by the unit Andro-Gin. This combined treatment proved more effective as it induced long-term remission (two years and longer) in 60.5% patients. Unsatisfactory results were minimal. Without use of the unit unsatisfactory results were recorded in 35% patients.

    The surgical treatment of gastric cancer has better long-term survival rates when performed in patients with early gastric cancer. Worse results are obtained in treatment of advanced gastric cancer. Most patients in west centers are treated in advanced stages. A great number of them go through a surgical treatment unable by itself to cure them. the frequent local recurrence caused by failure of the surgical treatment has been keeping poor survival rates in patients with advanced gastric cancer for decades. The desire of improving survival is the reason of the use of adjuvant therapies. This paper achieved the retrospective study of the influence of preoperative radiation therapy (2000 cGy) in long-term survival rates (120 months) of patients with advanced gastric cancer on stages IIIa, IIIb and IV. The possible injuries caused in the liver and kidney were observed also as well as first group was treated by surgical and radiation therapies and the second received surgical treatment only. There was no statistical difference between the two groups when sex, age, race, occurrence of other diseases, nutritional assessment, TNM stage, occurrence of obstruction or bleeding caused by tumor, surgical procedure and hepatic and renal function were considered. Survival rates and changes on hepatic and renal function were statistically compared. The results showed a statistic improvement on the long-term survival rates of stage IIIa patients treated by preoperative radiation therapy. No statistic difference was observed on hepatic or renal function between the groups. No adverse influence of radiation therapy method was detected by the used parameters. There was no statistical difference between the two groups when immediate surgical complications were considered. (author) 112 refs., 34 tabs.

    OBJECTIVE Hodgkin's disease (HD) is a chemo and radio-sensitive hematologic malignancy. At the present time, improvement of its cure rate, reduction of its long-term detrimental effects, and maintenance of a good quality of life are the major concerns in the treatment of HD. In this study the results of a long -term follow-up from our cancer center was analyzed retrospectively in terms of efficacy and collateral side effects. METHODS The results were analyzed for 295 patients with histologicallyverified HD who were treated from 1970 to 2000, especially 182 patients treated from 1980 to 2000. Multivariant analysis (COX model ) was employed to elucidate the prognostic determinants. RESULTS The 5, 10 and 20-year survival for 295 patients with HD were 63.5%, 55.8% and 47.1% respectively with a median survival time of 172 months (28-352 months ). The median follow-up time was 43 months (17-352 months). The 5, 10 and 20 years overall survival and disease-free survival were 79.6%, 74.5%, 66.8% and 74.5% ,69.4%, 69.4% respectively for patients treated by regular chemotherapy and radiotherapy from 1980 to 2000. The incidence of late toxicities was low. An age of≥45 years, B symptoms and stage Ⅲ / Ⅳ were the main prognostic determinants (P=0.000, P=0.035 and P=0.047) in this clinical study. Stage Ⅰ/Ⅱ and nodularsclerosis were favorable factors in comparison with stages Ⅲ/Ⅳ and other histologic subtypes. CONCLUSIONS A chemotherapy-predominant modality plays an important role in the treatment of HD with promising long-term survival and fewer late toxicities. Further investigation for this simplified convenient comprehensive therapy is warranted.

    A total of 113 patients, excluding those with tumor, spondylitis, and idiopathic scoliosis, underwent anterior lumbar interbody fusion (ALIF) with autologous iliac crest graft between 1984 and 1991 at our department. The proportion of these who were failed back patients was higher than that reported in the literature. Evaluation of functional outcome was feasible in 80 patients, utilizing Oswestry and Marburg scores, which were closely intercorrelated. The overall results yielded an improvement in the Oswestry score of 35.7 percentage points. A subset of 52 patients who were evaluated twice, showed the same results at an average of 6.6 years as they did at 2.3 years following surgery. Functional results showed a weak correlation with postoperative height loss of the intervertebral space. Influencing factors for the functional result were: postoperative compensation claim, age, and obesity. Of the professional people involved, 19.4% did not return to any occupation. Patients satisfied with the result had significantly greater functional improvement. Younger patients with additional dorsal distraction prior to ALIF for reduction of severe spondylolisthesis fared better than patients with ALIF alone. The rate of complications was low and did not contribute to the postoperative functional result. On the basis of these results further prospective studies have been designed and are currently underway.

    Full Text Available The experience of horseshoe kidney transplant operations is significantly restricted. Transplant surgeons often refuse to use horseshoe kidney due to a number of serious abnormalities of vessels and upper urinary tract in these organs. However, the constant shortage of donor organs and an increase in patients on the waiting list for kidney transplantation make us reconsider our approach to the selection of donor organs. The aim of this work was to demonstrate our result of horseshoe kidney transplantation.

    To evaluate which factor(s) might predict excellent Snellen visual acuity results in unilateral nontraumatic pediatric aphakes. Retrospective review of all unilateral pediatric aphakic patients seen in a specialty contact lens clinic between 1982 and 2009. Inclusion criteria as follows: (1) cataract extraction before age 6 weeks, (2) no other health complications, (3) contact lens fitting within 3 weeks postsurgery, and (4) measurable subjective visual performance on a clinical Snellen acuity chart. Fifteen patients were identified: 10 patients with persistent fetal vasculature syndrome (PFV) and 5 patients with the diagnosis of idiopathic congenital cataract (ICC). Final Snellen acuity results showed seven patients (46.67%) developed excellent Snellen visual acuities (defined as 20/50 or better), four patients (26.67%) developed moderate Snellen visual acuities (20/125 to 20/60), and four total patients (26.67%) developed poor Snellen visual acuities (worse than 20/200). Analysis used descriptive statistics. Approximately 50% of our unilateral nontraumatic pediatric aphakic patients aged older than 5 years achieved excellent Snellen visual acuity in the aphakic eye. The amount of surgical or ocular complications seems to have an inverse relationship with Snellen visual acuity in PFV. Patching compliance, without implying cause-effect direction, also had a direct relationship with final Snellen visual acuity for patients. Early cataract extraction, good to moderate patching compliance, and aggressive early contact lens management can lead to moderate to excellent Snellen visual results in several unilateral pediatric aphakic patients.

    We present our experiences in fifteen high-risk surgical patients, with large bile duct stones, treated with endoscopic home-made biliary stents. We observed good immediate and mediate results in all patients, with a 19.9 months follow-up. In one case, acute cholangitis developed after 25 months and the patient died. Other three died of unrelated causes. None of the patients required surgery. We conclude that endoscopic stenting is a useful procedure in the treatment of large bile duct stones in poor-risk surgical patients.

    Conventional percutaneous coronary intervention for the treatment of in-stent restenosis (ISR) has shown a high rate of ISR (30-55%). Considering the need for both extrusion of hyperplastic intima and additional stent expansion, a cutting balloon might be more effective for the treatment of ISR. We prospectively assessed the immediate and 8-month outcome of balloon angioplasty using the Barath Cutting Balloon in 100 consecutive patients (mean age: 60.5 +/- 10.8 years, 71% male). In 73 lesions (73%), a good result was reached with the cutting balloon only. In 21 lesions (21%) postdilatation and in 6 lesions (6%) predilatation with a conventional balloon was necessary. The mean inflation pressure was 8.7 +/- 2.0 (range: 6.0-18.0) atm. Before the procedure the mean minimal luminal diameter (MLD) was 0.95 +/- 0.45 mm. Quantitative coronary analysis showed a mean diameter stenosis of 65%+/- 16%. Immediately after the procedure the mean MLD was 2.42 +/- 0.54 mm with a mean diameter stenosis of 19%+/- 13%. Two patients died during the follow-up period (1 stroke, 1 nonvascular). At 8-month follow-up 26 patients (26%) reported to have anginal complaints CCS class II-IV of whom 16 (16%) needed target lesion revascularization. Treatment of ISR using the Barath Cutting Balloon can be performed safely with good immediate results and a relatively low need for repeated target lesion revascularization at 8-month follow-up.

Methods: External valvuloplasty was applied in 83 patients with isolated GSV insufficiency. Follow-up consisted of venous color duplex scanning performed on the first postoperative day, the first postoperative month, and then annually. Valvular insufficiency, venous reflux, and venous thrombosis formation in the saphenofemoral junction were the main outcomes. Results: A complete clinical and radiological healing was observed in 50 patients (60%. In 13 cases (15.6%, a secondary surgical treatment was performed consisting of vena saphena magna high ligation/stripping and varicose vein excisions, mainly due to severe and progressive vena saphena magna valvular insufficiency and clinical persistence of symptoms. Eight patients (9.6% developed superficial vein thrombosis, and only one patient (1.2% developed deep vein thrombosis. Contact was lost from 32 patients (38.5% for different reasons. Conclusion: External valvuloplasty is an effective surgical technique for selected cases of isolated GSV insufficiency without extensive varicose dilatations. This alternative method can be safely administered as an alternative to high ligation and conventional GSV stripping. Keyword: vein, saphenous, insufficiency, external valv, valvuloplasty, varicosis

    Full Text Available INTRODUCTION: Rupture of tendon calcaneum is a common problem.There are proponents of both conservative and operative methods.Inadequate strength and re ruptures are frequent. To address both the problems we have chosen Lindholm technique and doing it for last 20 yrs with very good results. MATERIALS AND METHODS: From January 1994 to August 2013, 112 consecutive patients were treated by this method, 85 cases were fresh ruptures, 23 were neglected ruptures and four cases were re rupture after operation done elsewhere. Torn tendo calcaneum was repaired by Kessler suture, it was then augmented with two 8cm by 1cm turn down flap of gastrosoleus apponeurosis. Skin suture was done with utmost care. BK pop cast was done in equinus position of ankle for four weeks, followed by gradual weight bearing with heel raised shoe for six months. RESULTS: All patients went back to their pre injury activity level. In four patients there were superficial skin infection which healed without skin necrosis. One patient needed rotation flap. Evaluation was done by modified Rupp score. It was found to be excellent in 47% cases good in 43% cases and fair in 8% cases. CONCLUSION: Lindholm technique was originally described for neglected cases, we used it in all cases to avoid any complication in fresh cases and found it universally successful.

    Full Text Available Abstract Background The arthroscopic method offers a less invasive technique of Bankart repair for traumatic anterior shoulder instability. We would like to report the 2 year clinical outcomes of bio-absorbable suture anchors used in traumatic anterior dislocations of the shoulder. Methods Data from 79 shoulders in 74 patients were collected over 4 years (2004 - 2008. Each patient was followed-up over a period of 2 years. The patients underwent arthroscopic Bankart repair using bio-absorbable suture anchors for their shoulder instability. These surgeries were performed at a single institution by a single surgeon over the time period. The patients were assessed with two different outcome measurement tools. The University of California at Los Angeles (UCLA shoulder rating scale and the Simple Shoulder Test (SST score. The scores were calculated before surgery and at the 2-year follow-up. The recurrence rates, range of motion as well post-operative function and return to sporting activities were evaluated. Results SST results from the 12 domains showed a significant improvement from a mean of 6.1 ± 3.1 to 11.1 ± 1.8 taken at the 2-year follow-up (p Conclusion Arthroscopic Bankart repair with the use of suture anchors is a reliable treatment method, with good clinical outcomes, excellent post-operative shoulder motion and low recurrence rates.

    When treating the degenerative arthritis that follows scapholunate instability or scaphoid pseudarthrosis, excision of the scaphoid must be combined with a stabilisation of the midcarpal joint. Two alternatives have been proposed for that purpose: fusing the lunate, triquetrum, capitate and hamate (four corner fusion), 4CF; or limiting the arthrodesis to the lunate and capitate, preserving or excising the triquetrum. Previous reports have attributed a high level of complications to lunocapitate arthrodesis, mainly in respect of nonunion. We have reviewed 17 patients who had been treated with a lunocapitate fusion, after an 8 to 12-year follow-up period, and found similar results compared with 4CF, even with a major degree of motion in ulnar-radial deviation. Recent work on the innervation of the radiotriquetral ligaments has given relevance to the preservation of lunotriquetral motion in maintaining proprioception. Also if the triquetrum is excised to gain more motion, the proprioceptive role of the radiotriquetral ligaments is compromised.

    A new Resistive Plate Chamber (RPC) based fast muon trigger system has been developed and partially installed in the PHENIX experiment. This new trigger will allow the PHENIX data acquisition system to efficiently sample high p{sub T} (>20GeV/c) muons from W decays in polarized proton+proton collisions at {radical}(s)=500GeV at the Relativistic Heavy Ion Collider at Brookhaven National Laboratory. This measurement will significantly improve our knowledge of flavor separated quark and anti-quark polarization in the proton. Since 2005, a multi-institutional effort within the PHENIX Forward Trigger group was devoted to study the properties and performance of bakelite RPCs. In this presentation, the results of the PHENIX RPC R and D will be reported.

    Full Text Available Alkaptonuria is a rare metabolic disease caused by a partial or total deficiency of homogentisic acid oxidase, which results in excess homogentisic acid (HGA levels. Homogentisic acid and its oxidation products can accumulate in hyaline cartilage, tendons, and ligaments. A 55-year-old male was admitted complaining of worsening chronic pain in his left knee. A radiographic evaluation showed tricompartmental end- stage osteoarthritis. A cemented total knee replacement was performed. At the 10-year follow-up, he had returned to full activity, had no knee pain, and was very satisfied with the outcome. No abnormality was observed in the femoral, tibial, or patellar components on radiography. We believe that total knee replacement is a good option in a patient with marked degenerative arthritis secondary to ochronotic arthritis.

    Ocean acidification may affect zooplankton directly by decreasing in pH, as well as indirectly via trophic pathways, where changes in carbon availability or pH effects on primary producers may cascade up the food web thereby altering ecosystem functioning and community composition. Here, we present results from a mesocosm experiment carried out during 113 days in the Gullmar Fjord, Skagerrak coast of Sweden, studying plankton responses to predicted end-of-century pCO2 levels. We did not observe any pCO2 effect on the diversity of the mesozooplankton community, but a positive pCO2 effect on the total mesozooplankton abundance. Furthermore, we observed species-specific sensitivities to pCO2 in the two major groups in this experiment, copepods and hydromedusae. Also stage-specific pCO2 sensitivities were detected in copepods, with copepodites being the most responsive stage. Focusing on the most abundant species, Pseudocalanus acuspes, we observed that copepodites were significantly more abundant in the high-pCO2 treatment during most of the experiment, probably fuelled by phytoplankton community responses to high-pCO2 conditions. Physiological and reproductive output was analysed on P. acuspes females through two additional laboratory experiments, showing no pCO2 effect on females’ condition nor on egg hatching. Overall, our results suggest that the Gullmar Fjord mesozooplankton community structure is not expected to change much under realistic end-of-century OA scenarios as used here. However, the positive pCO2 effect detected on mesozooplankton abundance could potentially affect biomass transfer to higher trophic levels in the future. PMID:28410436

    Full Text Available The weed composition and the dominance of individual species occurring in an orchard were assessed at the Research Station of the Wrocław University of Environmental and Life Sciences, Poland, during the first 10 years after orchard establishment. ‘Ligol’ apple trees were planted in the spring of 2004 (3.5 × 1.2 m. Foliar herbicides were applied in 1 m wide tree rows twice or three times per each vegetation period. In the inter-row spaces, perennial grass was maintained. Ten years of maintenance of herbicide fallow contributed to a change in the weed composition in the orchard. It changed as a result of different responses of the most important weed species to the foliar herbicides. Total suppression of Elymus repens was observed in the first year after planting the trees. Convolvulus arvensis, Cirsium arvense, and other perennial weeds, completely disappeared in the succeeding periods. The maintenance of herbicide fallow did not affect the abundance of Taraxacum officinale. The percentage of the soil surface covered by Trifolium repens and Epilobium adenocaulon, perennial weeds with considerable tolerance to post-emergence herbicides, increased during the fruit-bearing period of the trees. The abundance of these weeds was significantly reduced only in the rows with the stronger growing trees on the semi-dwarf P 2 rootstock. Stellaria media was the dominant annual weed. Senecio vulgaris, Poa annua, Capsella bursa-pastoris, and Lamium spp. were also frequently observed. A significant increase in the abundance of annual and perennial weeds was found in the tree rows as a result of improved water availability after a period of high precipitation.

    The aim of this work was to assess the efficacy of external myotomy of the upper esophageal sphincter (UES) for oropharyngeal dysphagia. In the period 1991–2006, 28 patients with longstanding dysphagia and/or aspiration problems of different etiologies underwent UES myotomy as a single surgical treatment. The main symptoms were difficulties in swallowing of a solid-food bolus, aspiration, and recurrent incidents of solid-food blockages. Pre- and postoperative manometry and videofluoroscopy were used to assess deglutition and aspiration. Outcome was defined as success in the case of complete relief or marked improvement of dysphagia and aspiration and as failure in the case of partial improvement or no improvement. Initial results showed success in 21 and failure in 7 patients. The best outcomes were observed in patients with dysphagia of unknown origin, noncancer-related iatrogenic etiology, and neuromuscular disease. No correlation was found between preoperative constrictor pharyngeal muscle activity and success rate. After follow-up of more than 1 year, 20 patients were marked as success and 3 as failure. All successful patients had full oral intake with a normal bolus consistency without clinically significant aspiration. We conclude that in select cases of oropharyngeal dysphagia success may be achieved by UES myotomy with restoration of oral intake of normal bolus consistency. PMID:19760460

    Objectives To assess the effects of elder-clowning on moderate to severe behavioral and psychological symptoms of dementia (BPSD) in nursing home residents with dementia, primarily of the Alzheimer’s type. Design Before-after study. Setting Nursing home. Participants Twenty-three nursing home residents with moderate to severe BPSD defined by the Neuropsychiatric Inventory-Nursing Home version (NPI-NH) score of ≥10, and their care aides. Intervention A pair of elder-clowns visited all residents twice weekly (approximately 10 minutes per visit) for 12 weeks. They utilized improvisation, humor and empathy, as well as expressive modalities such as song, musical instruments, and dance to individualize resident engagement. Measurements Primary outcomes were BPSD measured by the NPI-NH, quality of life measured by Dementia Care Mapping (DCM), and nursing burden of care measured by the Modified Nursing Care Assessment Scale (M-NCAS). Secondary outcomes included occupational disruptiveness measured by the NPI-NH, agitation measured by the Cohen Mansfield Agitation Inventory (CMAI), and psychiatric medication use. Results Over 12 weeks, NPI-NH scores significantly declined (t22 = −2.68, p = 0.01) and DCM quality of life scores significantly improved (F1,50 = 23.09, p clowning reduced moderate to severe BPSD of nursing home residents with dementia, primarily of the Alzheimer’s type. Elder-clowning is a promising intervention that may improve Alzheimer’s dementia care for nursing home residents. PMID:26889843

    The artificial geochemical land where all organisms lived and will live under the conditions of increased level of radiation was set up due to the Chernobyl disaster in 1986. An urgent necessity for studying the various biological effects of chronic influence of low intensity radiation on both individual organisms and populations arose. Combined cytogenetic and radioecological investigations in wild populations of terrestrial small mammals (bank vole = Clethrionomys glareolus, Schreber and yellow-necked mouse = Apodemus flavicollus, Melchior) and in laboratory mice have been carried out by our laboratory since 1986. Our test organisms have contacted closely with low intensity radiation in the radiocontaminated areas of Belarus and absorbed low whole-body dose. We study the following problems: dynamics of radionuclide concentration in wild populations of small rodents; dynamics of mutation process in somatic and germ cells over many generations as well as embryonal lethality; dynamics of population density, age and sex structure of mammalian populations. The large part of results obtained are presented here. (J.P.N.)

    AIM: Although most patients with achalasia respond to pneumatic dilation, one-third experienced recurrence, and prolonged follow-up studies on parameters associated with various outcomes are scanty. In this retrospective study, we reported a 15-years' experience with pneumatic dilation treatment in patients with primary achalasia, and determined whether previously described predictors of outcome remain significant after endoscopic dilation.METHODS: Between September 1989 and September 2004, 39 consecutive patients with primary symptomatic achalasia (diagnosed by clinical presentation, esophagoscopy,barium esophagogram, and manometry) who received balloon dilation were followed up at regular intervals in person or by phone interview. Remission was assessed by a structured interview and a previous symptoms score.The median dysphagia-free duration was calculated by Kaplan-Meier analysis.RESULTS: Symptoms were dysphagia (n = 39, 100%),regurgitation (n =23, 58.7%), chest pain (n = 4, 10.2%),and weight loss (n = 26, 66.6%). A total of 74 dilations were performed in 39 patients; 13 patients (28%) underwent a single dilation, 17 patients (48.7%) required a second procedure within a median of 26.7 mo (range 5-97 mo), and 9 patients (23.3%) underwent a third procedure within a median of 47.8 mo (range 37-120 mo). Post-dilation lower esophageal sphincter (LES) pressure, assessed in 35 patients, has decreased from a baseline of 35.8±10.4-10.0±7.1 mmHg after the procedure. The median follow-up period was 9.3 years (range 0.5-15 years). The dysphagiafree duration by Kaplan-Meier analysis was 78%, 61%and 58.3% after 5, 10 and 15 years respectively.CONCLUSION: Balloon dilation is a safe and effective treatment for primary achalasia. Post-dilation LES pressure estimation may be useful in assessing response.

    Full Text Available The Loaded Disc Culture System (LDCS is an Intervertebral Disc (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, 8 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 (Detiger et al., 2013; Paul et al., 2013, 2012, 4 of these IVDs were kept in physiological condition (control and the other 4 were previously injected with chondroitinase ABC (CABC, in order to promote Degenerative Disc Disease (DDD. The loading profile intercalated 16h of activity loading with 8h of loading recovery to express the standard circadian variations.The displacement behavior of these 8 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 2 of the 4 IVDs. The 4 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 describe the recovery

  8. Transitioning MODIS to VIIRS observations for Land: Surface Reflectance results, Status and Long-term Prospective

    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.

    Standing fracture repair in the horse is a recently described surgical procedure and currently there are few follow-up data. This case series contains 2 novel aspects in the standing horse: repair of incomplete sagittal fractures of the proximal phalanx and medial condylar repair from a lateral aspect. To describe outcome in a case series of horses that had lower limb fractures repaired under standing sedation at Rossdales Equine Hospital. Case records for all horses that had a fracture surgically repaired, by one surgeon at Rossdales Equine Hospital, under standing sedation and local anaesthesia up until June 2011, were retrieved. Hospital records, owner/trainer telephone questionnaire and the Racing Post website were used to evaluate follow-up. Thirty-four horses satisfied the inclusion criteria. Fracture sites included the proximal phalanx (incomplete sagittal fracture, n = 14); the third metacarpal bone (lateral condyle, n = 12, and medial condyle, n = 7); and the third metatarsal bone (lateral condyle, n = 1). One horse required euthanasia due to caecal rupture 10 days post operatively. Twenty horses (66.7% of those with available follow-up) have returned to racing. Where available, mean time from operation to return to racing was 226 days (range 143-433 days). Standing fracture repair produced similar results to fracture repair under general anaesthesia in terms of both the number of horses that returned to racing and the time between surgery and race. Repair of lower limb fracture in the horse under standing sedation is a procedure that has the potential for tangible benefits, including avoidance of the inherent risks of general anaesthesia. The preliminary findings in this series of horses are encouraging and informative when discussing options available prior to fracture repair. © 2012 EVJ Ltd.

    The aim of the study was to assess the safety and efficacy of CT-guided percutaneous radiofrequency (RF) ablation of osteoid osteoma (OO). From 1997 to 2001, RF ablation was performed on 38 patients with OO, diagnosed clinically and by radiography, scintigraphy, contrast-enhanced MRI, and CT. Treatment was performed via percutaneous (n=29) or surgical (n=9) access, under CT guidance in all cases, with an 18-gauge straight electrode. Patients were discharged within 24 h and followed up clinically (at 1 week and every 6-12 months) and with MRI (at 6 months) and scintigraphy (after 1 year). The technical success rate was 100%. Complications occurred in two patients, consisting in local skin burns. The follow-up range was 12-66 months (mean {+-} SD, 35.5{+-}7.5 months). Prompt pain relief and return to normal activities were observed in 30 of 38 patients. Persistent pain occurred in eight patients; two patients refused further RF ablation and were treated surgically; RF ablation was repeated in six cases achieving successful results in five. One patient reported residual pain and is being evaluated for surgical excision. Primary and secondary clinical success rates were 78.9 (30/38 patients) and 97% (35/36 patients), respectively. CT-guided RF ablation of OO is safe and effective. Persistent lesions can be effectively re-treated. Several imaging modalities are needed for the diagnosis of OO and for the follow-up after treatment, particularly in patients with persistent symptoms. (orig.)

    AIM: To evaluate the role of azathioprine (AZA) in Indian patients with ulcerative colitis over longer duration of time.METHODS: One hundred fifty six patients with ulcerative colitis who were treated with AZA from .January 1995 to December 2003 were reviewed. The indications for its use were as follows: (1) steroid dependent and steroid refractory disease; (2) Azathioprine monotherapy for na(i)ve patients with severe disease; and (3) combination therapy (AZA + sulfasalazine or 5-aminosalicylates) for na(i)ve patients with severe disease. The data included patient and disease demographics, efficacy and toxicity profile of AZA. Patients with a minimum duration of 6 mo use of AZA were included in this report.RESULTS: Of a total of 156 patients treated with AZA,45 were excluded from analysis for the following reasons(follow up less than 6 mo,n = 9; poor follow up,n = 18;adverse affects,n = 18). In steroid refractory/dependent group the mean number of relapses prior to and post initiation of AZA therapy were 3.28 (± 0.81) and 0.94 (±0.29) respectively. Discontinuation of steroids could be accomplished in 12 of the 15 steroid dependent patients.The proportion of patients with sustained remission of 1,2, 3, 4 and 5 years duration were calculated. Eighteen patients experienced adverse effects necessitating withdrawal of AZA (pancreatitis,n = 7; hepatitis,n = 3; gastrointestinal intolerance,n = 2; alopecia,n = 2; and hematological, n = 4) while 13 patients needed dose reduction or temporary withdrawal of the drug.CONCLUSION: Azathioprine is well tolerated and has therapeutic benefits lasting as long as 4 years. Adverse effects such as pancreatitis, hepatitis, cytopenias and gastrointestinal symptoms do occur but are controlled by drug withdrawal only.

    Full Text Available INTRODUCTION Surgically important variations of the sectoral and segmental bile ducts of the right lobe of the liver appear in a significant proportion of patients. Frequency of the injuries to these ducts is not known as the ligature of small ducts may pass without major consequences. MATERIAL AND METHODS Over a 27 year period (1. Jan 1974-31. Dec 2001 along with 168 patients with benign biliary strictures of type I, II, III and IV according to Bismuth's classification, we treated 13 patients with operative sectoral or segmental bile duct injuries, four patients from our institution and nine patients transferred from elsewhere. The injury was recognized at original surgery in all four patients operated in our institution. Primary repair was performed in three patients, in two patients direct end-to-end repair overT-tube and in one patient with anastomosis between the injured duct and Roux-en-Y jejunal limb, while in one patient the injured duct was ligated. In no one of nine patients transferred from elsewhere the injury was recognized during original surgery. Four patients were sent with biliary peritonitis, another four patients with external biliary fistula and one patient for pain and fever due to liver abscess. RESULTS All three patients in whom the primary repair was performed had a quick and uneventful recovery and they stayed symptom-free so far. The patient in whom the injured duct was ligated died after series of complications. Four patients sent to us with biliary peritonitis were treated with relaparotomy, lavage and drainage and all developed external biliary fistula. Three of these patients had their fistula ceased spontaneously within few weeks, while in one patient the fistula didn't show signs of ceasing so that injured duct had to be anastomosed with Roux-en-Y jejunal limb. Two out of four patients sent for external biliary fistula had it ceased spontaneously, while in two patients anastomosis between duct and Roux

    A flexible, reusable skin mold (weight 110 g) was developed for use with a pulsed dose rate (PDR) afterloader. An array of 18 parallel catheters (2 mm diameter) at equal distances of 10 or 12 mm was constructed by fixation of the catheters in a plastic wire mesh. The array is sewn between 2 foam rubber slabs of 5 mm thickness to provide a defined constant distance to the skin. Irradiations are possible up to a maximum field size of 20x23,5 cm using a nominal 37 GBq Ir-192 source. Pulses of 1 Gy reference dose at the skin surface are applied at a rate of 1 pulse every 1.2 hours (0.8 Gy per hour). The dose distribution is geometrically optimized to provide a homogeneous skin dose (100%{+-}10%). The 80% dose level lies at 5 mm below the skin surface. Between April 1994 and December 1997, 52 patients suffering from cutaneous metastases at the thoracic wall were treated with 54 fields and total doses of 38 to 50 Gy (median 42 Gy) applying 2 PDR courses with a pause of 4 to 5 weeks. Results: Forty-six patients (48 fields) were eligible for evaluation in June 1998. The median follow-up was 16 months (range 7.1 to 46.2 months). Local control was achieved in 40 out of 48 fields (83%) or 41 of 46 patients (89%), respectively. Moist desquamation occurred in 52% of the patients. Late reactions were judged after a minimum follow-up of 6 months. Thirty-two fields had been previosuly irradiated with external beam therapy to doses of 40 to 60 Gy. Regardless of whether the skin was preirradiated or not all patients surviving long enough developed telangiectasia within 2 years after PDR irradiation. In preirradiated patients (n=32) skin contractures and/or skin necrosis occurred in 12% each. In newly irradiated patients (n=14) no contractures or skin necrosis were observed. (orig.)

    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.

    Aim: To evaluate the long-term results of percutaneous imaging-guided treatment of hydatid liver cysts. Materials and methods: Sixty patients with 77 hydatid liver cysts underwent percutaneous treatment with ultrasonography (US) or computed tomography (CT) guidance. Absolute alcohol and hypertonic saline were used for sclerosing the cysts after aspiration. Prophylactic albendazole treatment was given before and after the procedures. Follow-up US and CT were obtained periodically, and changes in cyst morphology were recorded. Minimum follow-up period for the patients included in this study was 12 months. Serological correlation was also available for a group of patients. The outcome of the procedures were categorized into five groups based on morphological changes observed by imaging. Results: Procedures were regarded as successful in 80% and unsuccessful in 20% of patients. Failures most often occurred with type III cysts; less than half (39%) of the total type III cysts had a successful outcome. On the other hand, all type I cysts ended up with cure. Anaphylaxis, pneumotorax and severe pain interrupting the procedures were also among the reasons of failure. Conclusion: Percutaneous aspiration, injection and reaspiration (PAIR) of types I and II hydatid liver cysts is effective and safe in the long-term. Surgery should no longer be regarded as the first choice treatment in all hydatid liver cysts but should be reserved for type III and certain active type IV cysts.

    Full Text Available Choroidal osteoma is an uncommon benign osseous intraocular tumor typically seen unilaterally in young women. Visual loss can occur due to choroidal neovascularization (CNV complicating osteoma. We report a rare case of bilateral choroidal osteoma with secondary CNV in a young male and the long-term results following anti-vascular endothelial growth factor (VEGF therapy. A 30-year-old male with history of defective vision in both eyes since several years and recent worsening in the right eye (RE since 2 months was found to have bilateral macular osteoma with CNV in the RE based on clinical evaluation, fluorescein angiography, optical coherence tomography, and ultrasonography. Intravitreal injection of ranibizumab at monthly intervals for three doses resulted in resolution of CNV and remained stable for 5 years. Recurrent CNV detected 6 years later responded to an injection of intravitreal bevacizumab and has remained stable till date. Anti-VEGF therapy stabilized the secondary CNV in our patient for 7 years with satisfactory structural and functional outcome, demonstrating the long-term efficacy of this modality of treatment.

    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). 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.

    Differences were found between patients with stable hearing and those with progressive hearing loss in the lower frequencies with respect to the rate of progression in the contralateral ear. It is suggested that the electric acoustic stimulation (EAS) can provide improvement in hearing ability over the long-term if residual hearing might be lost to some extent. To evaluate the long-term threshold changes in the low frequency hearing of the implanted ear as compared with the non-implanted ear, and the hearing abilities with EAS along with the extent of residual hearing. Seventeen individuals were enrolled and received the EAS implant with a 24-mm FLEXeas electrode array. Hearing thresholds and speech perception were measured pre- and post-operatively for 1-5 years. Post-operative hearing preservation (HP) rates were calculated using the preservation numerical scale. The average linear regression coefficient for the decline in hearing preservation score was -6.9 for the implanted ear and the patients were subsequently categorized into two groups: those with better than average, stable hearing; and those with worse than average, progressive hearing loss. EAS showed better results than electric stimulation alone, in spite of an absence of speech perception with acoustic stimulation.

    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.

    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.

    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.

    Full Text Available Introduction. Laparoscopic Sleeve Gastrectomy (SG is considered as successful if the percentage of Excess Body Mass Index Loss (% EBMIL remains constant over 50% with long-term follow-up. The aim of this study was to evaluate whether early % EBMIL was predictive of success after SG. Methods. This retrospective study included patients who had SG with two years of follow-up. Patients had follow-up appointments at 3 (M3, 6, 12, and 24 months (M24. Data as weight and Body Mass Index (BMI were collected systematically. We estimated the % EBMIL necessary to establish a correlation between M3 and M24 compared to % EBMIL speeds and calculated a limit value of % EBMIL predictive of success. Results. Data at operative time, M3, and M24 were available for 128 patients. Pearson test showed a correlation between % EBMIL at M3 and that at M24 (r=0.74;  p<0.0001. % EBMIL speed between surgery and M3 (p=0.0011 was significant but not between M3 and M24. A linear regression analysis proved that % EBMIL over 20.1% at M3 (p<0.0001 predicted a final % EBMIL over 50%. Conclusions. % EBMIL at M3 after SG is correlated with % EBMIL in the long term. % EBMIL speed was significant in the first 3 months. % EBMIL over 20.1% at M3 leads to the success of SG.

    To evaluate the long-term functional results of arthroscopic abrasion arthroplasty for the treatment of full-thickness cartilage lesions of the medial femoral condyle. Between 1990 and 1996, 75 consecutive patients with isolated chondral lesions of the medial femoral condyle were treated with arthroscopic chondral abrasion. A retrospective analysis of the clinical results of this cohort was performed. The patients were evaluated according to the Knee Society Score questionnaire preoperatively, at 10 years postoperatively, and at final long-term follow-up at a mean of 20 years. At final follow-up, they were also assessed according to the Western Ontario and McMaster Universities Osteoarthritis Index. Patients were divided according to the lesion size and by age, and the Kaplan-Meier survivorship function (with second operation taken as an endpoint) for the various groups was calculated. At a mean of final follow-up of 20 years (range, 16.94 to 23.94 years), a positive functional outcome (Knee Society Score ≥70 points or no reoperation) was recorded in 67.9% of the patients. Twenty-year survivorship in this cohort was 71.4% (95% confidence interval, 0.5690 to 0.8590). The survivorship was 89.5% for patients younger than 50 years and 55.7% for patients aged 50 years or older. The functional results for patients with lesions smaller than 4 cm(2) were significantly better than those for patients with lesions of 4 cm(2) or greater (P = .031). There were no statistical differences between patients with and without associated lesions at the time of surgery. Our hypothesis that there would be survivorship greater than 86% was disproved. However, arthroscopic abrasion arthroplasty can be a valid treatment for medial femoral condylar full-thickness defects of the knee, even in the long-term, particularly for younger patients and those with smaller lesions.

Success was defined as freedom from AF, atrial flutter, or atrial tachycardia off antiarrhythmic drugs. RESULTS: AF was paroxysmal in 77.7%, persistent in 12.2% and long-standing persistent in 10.1%. Single-procedure success rate was 71.7%, 59.4% and 46.6% at 12, 24 and 60 months respectively. Single-procedure success rate was 72.9%, 62.6% and 51.8% for paroxysmal AF, 64.7%, 35.3%, and 28.2% for persistent AF, 71.4%, 64.3% and 28.6% for long-standing persistent AF at 12, 24 and 60 months respectively. Duration of AF>24 months (hazard ratio [HR]: 3.09, 95% confidence interval [CI]: 1.51 to 6.32; p = 0.002, left atrial diameter≥40 mm (HR: 4.03, 95% CI: 1.88 to 8.65; p<0.001, early recurrence of AF (HR: 4.66, 95% CI: 2.25 to 9.63; p<0.001 independently predicted long-term recurrence of AF. There was no procedure-related death. One patient converted to median sternotomy because of uncontrolled bleeding. Two patients underwent perioperative cerebrovascular events. CONCLUSIONS: At nearly 5-year of clinical follow-up, single-procedure success rate of minimally invasive surgical PVI with GP ablation was 51.8% for paroxysmal AF, 28.2% for persistent AF, 28.6% for long-standing persistent AF after initial procedure. Patients with AF duration≤24 months, left atrial diameter<40 mm and no early recurrence of AF, had favorable outcomes.

    Percutaneous transluminal angioplasty (PTA) was carried out 52 times for 49 lesions in 47 cases of atheroscrelotic stenosis of the intracranial or skull base cerebral arteries. The stenotic lesions involved the middle cerebral artery in 21 cases, the basilar artery in eight cases, the internal carotid artery (petrous-supraclinoid portion) in 15 cases, and the intracranial vertebral artery in five cases. Nearly all cases were symptomatic, such as TIA or stroke, and the degree of stenosis ranged from 70 to 99 percent, with a mean of 80 percent. PTA was performed using a STEALTH balloon angioplasty catheter. In these trials, PTA was successfully performed (as indicated by a residual stenosis under 50%) 41 times. The initial success rate was 79% and stenosis was reduced from 80% to 25%. Clinical follow-up was performed from 7 to 84 months with a mean of 44 months. During this period, death due to myocardial infarction or pneumonia occurred in five cases, stroke related to previous PTA occurred ih one case (due to re-stenosis) and stroke unrelated tl? previous PTA occurred in two cases. Angiographic follow-up was performed in 31 cases after 41 successful PTA procedures. Re-stenosis was seen in 20% of the cases, symptomrltic complications occurred in 6%, and asymptomatic complications occurred in 6% of the cases. One case suffered severe subarachnoid hemorrhage just after the PTA due to preexisting aneurysm rupture and he died a week after the PTA. So mortality in this series was 2%. From the results described here, we may conclude that PTA of the intracranial or skull base cerebral artery is technically feasible, and it can be performed with relatively low risk. From our results, it may be a useful method and effective for long-term survival of patients. But results from a larger number of patients and more long-term follow-up data are still necessary in order to evaluate the safety and usefulness of this method.

    The purpose of this study is to report and analyze the long-term outcomes of the patients who underwent high tibial osteotomy (HTO) with three different techniques for the treatment of medial compartment arthrosis. A total of 187 patients (195 knees) who underwent HTO between 1990 and 2010 were retrospectively evaluated. Eighty-eight knees, opening-wedge osteotomy with Puddu plate (group A); 51 knees, transverse osteotomy below the tubercle with external fixator (group B); and 29 knees, closing-wedge osteotomy with staple fixation (group C) were included in the study. The patients (mean age 44.9 ± 10.6 years, mean follow-up of 12.4 ± 3.2 years) were called for final controls and survival rates of the knees, and functional evaluations of the patients were performed using Knee Society Score (KSS) and Hospital for Special Surgery (HSS) knee score assessments. In the comparison of the three groups, there were no differences regarding the mean age, preoperative arthrosis levels, or preoperative deformity analyses (n.s.). The main finding of these comparisons showed that the closing-wedge osteotomy has the greatest lateralization effect on mechanical axis deviation (MAD) (p = 0.024), the greatest valgization effect on medial proximal tibial angles (MPTA) (p = 0.026), and the lowest posterior tibial slope (PTS) angles (p = 0.032) in comparison to the other groups. There were no functional differences between the three groups in the long-term assessment of patients with KSS and HSS knee scores. According to the Kaplan-Meier survival analysis, the probability of the survival of the native knee joint after HTO was 93.4% in 5 years and 71.2% in 10 years in our study group. During the follow-up of the 168 knees, revision surgery with total knee replacement was needed in 27 knees (16%). The mean time from HTO to total knee replacement was 8.9 years in these patients. HTO has acceptable long-term clinical and functional results that should not be

    Background and Purpose: In early-stage Dupuytren's contracture, radiotherapy is applied to prevent disease progression. Long-term outcome and late toxicity of the treatment were evaluated in a retrospective analysis. Patients and Methods: Between 12/1982 and 02/2006, 135 patients (208 hands) were irradiated with orthovoltage (120 kV; 20 mA; 4-mm Al filter), in two courses with five daily fractions of 3.0 Gy to a total dose of 30 Gy; separated by a 6- to 8-week interval. The extent of disease was described according to a modified classification of Tubiana et al. Long-term outcome was analyzed at last follow-up between 02/2008 and 05/2008 with a median follow-up of 13 years (range, 2-25 years). Late treatment toxicity and objective reduction of symptoms as change in stage and numbers of nodules and cords were evaluated and used as evidence to assess treatment response. Results: According to the individual stages, 123 cases (59%) remained stable, 20 (10%) improved, and 65 (31%) progressed. In stage N 87% and in stage N/I 70% remained stable or even regressed. In more advanced stages, the rate of disease progression increased to 62% (stage I) or 86% (stage II). 66% of the patients showed a long-term relief of symptoms (i.e., burning sensations, itching and scratching, pressure and tension). Radiotherapy did not increase the complication rate after surgery in case of disease progression and only minor late toxicity (skin atrophy, dry desquamation) could be observed in 32% of the patients. There was no evidence for a second malignancy induced by radiotherapy. Conclusion: After a mean follow-up of 13 years radiotherapy is effective in prevention of disease progression and improves patients' symptoms in early-stage Dupuytren's contracture (stage N, N/I). In case of disease progression after radiotherapy, a ''salvage'' operation is still feasible. (orig.)

    We reviewed 95 ankles at an average of 9 years after an "activo-passive" operation performed for chronic lateral instability. All the patients had suffered recurrent ankle sprain or instability, with pain in 67 patients. Ten ankles showed a subtalar injury at operation. Degenerative changes were noted in 11 ankle joints. On review, 81 ankles (85%) were stable. The 14 cases with persistent instability had developed the problem one to five years after operation. Two cases presented with limitation in mobility. Osteoarthritis, found in 15 ankles, was severe in only two, and had been present on preoperative films. We found no correlation between functional results (talar tilt, anterior-drawer test) and radiological evaluation. The "activo-passive" operation provides long-term stabilization with preservation of the ankle and of subtalar mobility without severe osteoarthritis.

    Objectives To address whether menopause affects outcome of catheter ablation (CA) for atrial fibrillation (AF) by comparing the safety and long-term outcome of a single-procedure in pre-and post-menopausal women. Methods A total of 743 female patients who underwent a single CA procedure of drug-refractory AF were retrospectively analyzed. The differences in clinical presentation and outcomes of CA for AF between the pre-menopausal women (PreM group, 94 patients, 12.7%) and the post-menopausal women (PostM group, 649 patients, 87.3%) were assessed. Results The patients in the PreM group were younger (P<0.001) and less likely to have hypertension (P<0.001) and diabetes (P=0.005) than those in the PostM group. The two groups were similar with regards to the proportion of concomitant mitral valve regurgitation coronary artery disease, left atrium dimensions, and left ventricular ejection fraction. The overall rate of complica-tions related to AF ablation was similar in both groups (P=0.385). After 43 (16-108) months of follow-up, the success rate of ablation was 54.3%in the PreM group and 54.2%in the PostM group (P=0.842). The overall freedom from atrial tachyarrhythmia recurrence was simi-lar in both groups. Menopause was not found to be an independent predictive factor of the recurrence of atrial tachyarrhythmia. Conclusions The long-term outcomes of single-procedure CA for AF are similar in pre-and post-menopausal women. Results indicated that CA of AF appears to be as safe and effective in pre-menopausal women as in post-menopausal women.

    Full Text Available Abstract Background Expanding the information on determinants of smoking cessation is crucial for developing and implementing more effective tobacco control measures at the national as well as European levels. Data on smoking cessation and its social correlates among adults from middle-income countries of Central and Eastern Europe are still poorly reported in the literature. The aim of the study was to analyze the association of socio-demographic indicators with long term tobacco smoking cessation (quit smoking for at least one year prior to interview among adults. Moreover, we evaluated motives for giving up smoking from former smokers. Methods Data on former as well as current smokers’ socio-demographic and smoking-related characteristics were derived from the Global Adult Tobacco Survey (GATS. GATS is a cross-sectional, nationally representative household survey implemented in Poland between 2009 and 2010. GATS collected data on a representative sample of 7,840 individuals including 1,206 individuals who met the criteria of long-term smoking cessation and 2,233 current smokers. Smoking cessation rate was calculated as the number of former smokers divided by the number of ever smokers. Logistic regression analyses were used to obtain odds ratios (ORs and 95% confidence interval (CI of the broad number of variables on successful cessation of smoking. Results Among females the quit rate was 30.4% compared to 37.9% in males (p  Conclusion Results indicated that smoking cessation policies focused on younger age groups are vital for curbing tobacco epidemic in Poland and should become a public health main concern. There is also the need for interventions to raise awareness on smoking health risks and quitting benefits are crucial to increase cessation potential among adult smokers. Nevertheless further effort needs to be done to prevent smoking uptake.

    Repair of the neglected achilles tendon ruptures can be challenging due to retraction of tendon stumps. Different repair and augmentation techniques were described. This study aims to investigate long-term results of neglected achilles tendon rupture repair with gastrocnemius flaps. Between 1995 and 2005, 21 neglected achilles tendon rupture reconstructions were performed with using gastrocnemius fascial flaps. Mean age was 32.1 years. Mean period between rupture and operation was 8.4 weeks. Ankle range of motion, calf circumference, heel raise test, Visual Analog Scale (VAS), American Orthopedic Foot and Ankle Society (AOFAS) hindfoot and Foot and Ankle Disability Index (FADI) scores were checked. The average gap length was 6.4 cm. Mean follow-up was 145.3 months. Median dorsiflexion/plantar flexion values for operated and uneffected sides were 18°/30° and 19°/30°, respectively. The mean values for AOFAS and FADI scores were 98.5 points and 98.9 %, respectively. VAS score was 0 point for all patients. With the numbers available, no significant difference could be detected in terms of ankle range of motion, calf circumference measures and dynamometric analysis. Mean time for return to daily activities was 11.1 (8-16) weeks after surgery. Prerupture activity level was achieved 14.1 months postoperatively. All patients were able to perform heel raise test. Repair of neglected achilles tendon ruptures with gastrocnemius flaps has satisfactory long-term results.

    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.

    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. 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. In the NS 91% of the population had antibody levels above 0.01 IU/ml compared to 88% in the 1995/1996 serosurvey (pdiphtheria 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. 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 clustered orthodox Protestant community after introduction in the Netherlands has not disappeared, despite national long-term high vaccination coverage.

    In order to detect stellar activity cycles and study possible star-planet interactions (SPIs), we have been developing the HKα and SPI-HKα projects since 1999 and 2012 respectively. In this work, we present preliminary results of possible SPIs from studies of chromospheric activity and look for possible correlations between stellar activity and stellar/planetary parameters. We find that for stars with a similar Teff, stellar activity increases with the mass of the planet, similar to results from previous works. However, stellar ages can also play a role, and a larger stellar sample is needed to verify these trends. We also note that some of these stars present a remarkably high level of chromospheric activity, comparable even with RSCvn or BY Dra active stars. In addition, we do not observe any correlation between stellar activity and semi-major axis. We present the first long-term activity study of the star ι Horologii, a young solar-type star that hosts a non-transiting Jovian planet and exhibits a high activity level. We analysed our own spectra, obtained between 2002 and 2015, in conjunction with public HARPS (High Accuracy Radial velocity Planet Searcher) observations. We calculated the Ca II indexes derived from the 987 Complejo Astronómico El Leoncito (CASLEO) and HARPS spectra and converted them to the Mt Wilson scale. We found a long-term activity cycle of ˜5 yr which fits the active sequence of Böhm-Vitense. The amplitude of this longer cycle is irregular, as was also observed for the shorter cycle. This phenomenon could be attributable to an antisymmetric distribution of active regions on the stellar surface.

    Purpose: To retrospectively evaluate and compare the long term patency and antihypertensive effect of angioplasty and stent insertion in renal artery stenosis caused by Takayasu arteritis, with CT angiography and clinical follow-up. Materials and methods: We retrospectively analyzed and compared effects on hypertension and patency of renal artery in 16 patients (age ranging from 16 to 58 years, mean: 32.1 years) with renovascular hypertension caused by Takayasu arteritis who underwent endovascular treatment including angioplasty (n = 13) and stent placement (n = 9) for 22 stenotic renal arteries. Results: Technical success was 95% (21/22) without major complications. In the last follow-up CT angiogram (mean 85 ± 41 months), restenosis was 8% (1/12) in angioplasty and 66% (6/9) in stent. Patency rates of angioplasty were 100%, 91.7%, 91.7% and primary unassisted and primary assisted patency rates of stent placement were 55.6%, 33.3%, 33.3% and 88.9%, 66.7%, 55.6% at 1-, 3- and 5-years, respectively. In clinical follow-up (mean 120 ± 37.8 months, range 48–183 months), beneficial effects on hypertension were obtained in 87% of patients (13/15) and there was no significant difference between the patients who were treated by only angioplasty and the patients who received stent placement in at least one renal artery, regardless of whether or not angioplasty had been performed in the other renal artery. Conclusion: Compared with stent placement, angioplasty demonstrated better long term patency and similar clinical benefit on renovascular hypertension in renal artery stenosis of Takayasu arteritis. We suggest that stent placement should be reserved for obvious angioplasty failure.

    Purpose: biochemical control (bNED), disease-specific survival (DSS), overall survival (OS), and late gastrointestinal (GI) and urogenital (UG) side effects (EORTC/RTOG) of patients with long-term follow-up were evaluated. Patients and methods: three-dimensional radiotherapy up to 66 Gy with/without additional hormonal therapy was performed in 154 prostate cancer (T1-3 NO MO) patients. According to T-stage, pretreatment prostate-specific antigen (PSA) and grading, patients were divided into a low-, intermediate-, and high-risk group. The 5-, 8-, and 10-year actuarial rates of bNED, DSS and OS and late side effects were calculated. Results: median follow-up was 80 months. Additional hormonal therapy was given in 57% of patients. Distribution concerning risk groups (low, intermediate, high) showed 15%, 49%, and 36% of patients, respectively. bNED 5-, 8-, and 10-year actuarial rates were 46%, 44%, and 44%. DSS 5-, 8- and 10-year rates amounted to 96%, 90%, and 82%. OS 5-, 8- and 10-year rates were 81%, 64%, and 56%. In uni- and multivariate analysis, only pretreatment PSA (< 10 vs. {>=} 10 ng/ml; p < 0.05) and PSA nadir (< 0.5 vs. {>=} 0.5 ng/ml; p < 0.0001) affected bNED significantly. Age, risk group, T-stage, grading, and hormonal therapy had no significant influence on bNED, DSS, and OS. Rates of late GI and UG side effects grade {>=} 2 at 5 years were 17% and 15%. Conclusion: current dose escalation studies with better bNED rates may be able to further increase long-term clinical outcome. (orig.)

    Pancreatic ductal adenocarcinoma is one of the most malignant types of cancer. This study evaluated the 3-year and 5-year surgical outcomes associated with the cancer and determined whether statistically identified factors can be used to predict survival. This retrospective review was conducted from 1995 to 2010. Patients who had resectable pancreatic ductal adenocarcinoma and received surgical treatment were included. Cases of hospital mortality were excluded. The relationships between several clinicopathological factors and the survival rate were analyzed. A total of 223 patients were included in this study. The 3-year and 5-year survival rates were 21.4% and 10.1%, respectively, and the median survival was 16.1 months. Tumor size, N status, and resection margins were independent predictive factors for 3-year survival. Tumor size independently predicted 5-year survival. Tumor size is the most important independent prognostic factor for 3-year and 5-year survival. Lymph node status and the resection margins also independently affected the 3-year survival. These patient outcomes might be improved by early diagnosis and radical resection. Future studies should focus on the tumor biology of this aggressive cancer. Copyright © 2016.

    Full Text Available ABSTRACT 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.

    OBJECTIVE The aim of this study was to reappraise long-term treatment outcomes of stereotactic radiosurgery (SRS) for vestibular schwannomas (VSs). The authors used a database that included patients who underwent SRS with a unique dose-planning technique, i.e., partial tumor coverage designed to avoid excess irradiation of the facial and cochlear nerves, focusing on tumor control and hearing preservation. Clinical factors associated with post-SRS tumor control and long-term hearing preservation were also analyzed. METHODS This institutional review board-approved, retrospective cohort study used the authors' prospectively accumulated database. Among 207 patients who underwent Gamma Knife SRS for VSs between 1990 and 2005, 183 (who were followed up for at least 36 post-SRS months) were studied. The median tumor volume was 2.0 cm(3) (range 0.05-26.2 cm(3)). The median prescribed dose at the tumor periphery was 12.0 Gy (range 8.8-15.0 Gy; 12.0 Gy was used in 171 patients [93%]), whereas tumor portions facing the facial and cochlear nerves were irradiated with 10.0 Gy. As a result, 72%-99% of each tumor was irradiated with the prescribed dose. The mean cochlear doses ranged from 2.3 to 5.7 Gy (median 4.1 Gy). RESULTS The median durations of imaging and audiometric follow-up were 114 months (interquartile range 73-144 months) and 59 months (interquartile range 33-109 months), respectively. Tumor shrinkage was documented in 110 (61%), no change in 48 (27%), and enlargement in the other 22 (12%) patients. A further procedure (FP) was required in 15 (8%) patients. Thus, the tumor growth control rate was 88% and the clinical control rate (i.e., no need for an FP) was 92%. The cumulative FP-free rates were 96%, 93%, and 87% at the 60th, 120th, and 180th post-SRS month, respectively. Six (3%) patients experienced facial pain, and 2 developed transient facial palsy. Serviceable hearing was defined as a pure tone audiogram result better than 50 dB. Among the 66 patients with

    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.

    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

The conventional therapy is targeted to control the disease without targeting the loss of lung function or reversibility. In a prospective real-world observation of long-term use of add-on doxycycline as a matrix-metalloproteinase inhibitor, we documented significant improvement in lung function with possible reversal of remodeling.Background: Chronic asthma shows progressive decline in lung function with reduction or even loss of reversibility secondary to remodeling. A set of endopeptidase enzymes known as matrix metalloproteinases are intimately related to the pathogenesis of asthma and remodeling. The inhibition of matrix metalloproteinases is recognized as a prospective way of treating asthma and its corresponding structural remodeling.Methods: In a randomized, prospective, real-world study, we have observed the change in lung function (spirometry with an add-on of long-term doxycycline to standard asthma therapy as per the Global Initiative for Asthma guidelines in a small asthmatic population. The change in terms of forced expiratory volume (FEV1, forced vital capacity (FVC, percent of FEV1 (FEV1%, and forced expiratory flow (FEF25–75 were noted following variable duration of doxycycline therapy.Results: There has been a global improvement in all the parameters in all the six patients suggesting improvement in obstruction, and reduction in air trapping following a treatment of add-on doxycycline for a mean duration of 162.83 ± 83.07 days. Of the changes seen, the post bronchodilator FEV1, the FVC, and the FEF25–75 showed significant improvements with the P-value set at 0.004, 0.054, and 0.031, respectively.

    Full Text Available INTRODUCTION: Information on benefits and risks of drugs is a key element affecting doctors' prescribing decisions. Outreach visits promoting independent information have proved moderately effective in changing prescribing behaviours. OBJECTIVES: Testing the short and long-term effectiveness on general practitioners' prescribing of small groups meetings led by pharmacists. METHODS: Two cluster open randomised controlled trials (RCTs were carried out in a large scale NHS setting. Ad hoc prepared evidence based material were used considering a therapeutic area approach--TEA, with information materials on osteoporosis or prostatic hyperplasia--and a single drug oriented approach--SIDRO, with information materials on me-too drugs of 2 different classes: barnidipine or prulifloxacin. In each study, all 115 Primary Care Groups in a Northern Italy area (2.2 million inhabitants, 1737 general practitioners were randomised to educational small groups meetings, in which available evidence was provided together with drug utilization data and clinical scenarios. Main outcomes were changes in the six-months prescription of targeted drugs. Longer term results (24 and 48 months were also evaluated. RESULTS: In the TEA trial, one of the four primary outcomes showed a reduction (prescription of alfuzosin compared to tamsulosin and terazosin in benign prostatic hyperplasia: prescribing ratio -8.5%, p = 0.03. Another primary outcome (prescription of risedronate showed a reduction at 24 and 48 months (-7.6%, p = 0.02; and -9,8%, p = 0.03, but not at six months (-5.1%, p = 0.36. In the SIDRO trial both primary outcomes showed a statistically significant reduction (prescription of barnidipine -9.8%, p = 0.02; prescription of prulifloxacin -11.1%, p = 0.04, which persisted or increased over time. INTERPRETATION: These two cluster RCTs showed the large scale feasibility of a complex educational program in a NHS setting, and its potentially

    Full Text Available 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.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.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.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 clustered orthodox Protestant community

    To evaluate the long-term results following eccentric calf-muscle training in patients with chronic Achilles tendinopathy. A total of 24 patients with chronic Achilles tendinopathy were included in a study evaluating MRI findings and clinical symptoms before and after 3 months of daily eccentric calf-muscle strength training. Median duration of symptoms was 18 months (range 6-120). Four of the patients did not perform the prescribed treatment for different reasons and were followed for 14 months. The resulting 20 treated patients completed 4.2-year (range 29-58 months) follow up. Tendon volume was evaluated by using 3D seed growing technique and signal abnormalities were visually semi-quantitatively graded. Level of pain and performance was categorized using a questionnaire completed by the patient. In the symptomatic treated patients, median intensity level of pain decreased from moderate/severe at time of inclusion to mild at follow up (p < 0.05). Median level of performance increased from severe impairment at time of inclusion to normal at follow up (p < 0.05). 12 out of 20 patients had raised intratendinous signal at time of inclusion compared to 2 out of 20 patients at follow up (p < 0.001). Mean tendon-volume measured 6.7 cm{sup 3} (SD 2.0) at time of inclusion and 6.4 cm{sup 3} (SD 2.0) at follow up (p = 0.18). The four symptomatic non-treated tendons did not improve regarding pain, performance, intratendinous signal or tendon volume. We found decreased pain, improved performance and decreased intratendinous signal both compared to index examination and immediately after the 3 months training regimen in a 4.2-year clinical and MRI follow up, in a group of patients treated with heavy loaded eccentric calf-muscle training for chronic Achilles tendinopathy. The improvements were greater at 4.2-year follow up, despite no further active treatment, than immediately after the treatment. This may indicate a good long-term prognosis for Achilles tendinosis patients

    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.

    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.

    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.

    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).

    It is recommended that research in patients with idiopathic scoliosis should focus on short- and long-term patient-centred outcome. The aim of the present study was to evaluate outcome in patients with late-onset juvenile or adolescent idiopathic scoliosis 16 years or more after Boston brace treatment. 272 (78%) of 360 patients, 251 (92%) women, responded to follow-up examination at a mean of 24.7 (range 16 - 32) years after Boston brace treatment. Fifty-eight (21%) patients had late-onset juvenile and 214 had adolescent idiopathic scoliosis. All patients had clinical and radiological examination and answered a standardised questionnaire including work status, demographics, General Function Score (GFS) (100 - worst possible) and Oswestry Disability Index (ODI) (100 - worst possible), EuroQol (EQ-5D) (1 - best possible), EQ-VAS (100 - best possible), and Scoliosis Research Society - 22 (SRS - 22) (5 - best possible). The mean age at follow-up was 40.4 (31-48) years. The prebrace major curve was in average 33.2 (20 - 57)°. At weaning and at the last follow-up the corresponding values were 28.3 (1 - 58)° and 32.5 (7 - 80)°, respectively. Curve development was similar in patients with late-onset juvenile and adolescent start. The prebrace curve increased > 5° in 31% and decreased > 5° in 26%. Twenty-five patients had surgery. Those who did not attend follow-up (n = 88) had a lower mean curve at weaning: 25.4 (6-53)°. Work status was 76% full-time and 10% part-time. Eighty-seven percent had delivered a baby, 50% had pain in pregnancy. The mean (SD) GFS was 7.4 (10.8), ODI 9.3 (11.0), EQ-5D 0.82 (0.2), EQ-VAS 77.6 (17.8), SRS-22: pain 4.1 (0.8), mental health 4.1 (0.6), self-image 3.7 (0.7), function 4.0 (0.6), satisfaction with treatment 3.7 (1.0). Surgical patients had significantly reduced scores for SRS-physical function and self-image, and patients with curves ≥ 45° had reduced self-image. Long-term results were satisfactory in most braced patients and

    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.

    To evaluate the long-term clinical and manometric results of fistulotomy and sphincter reconstruction for the treatment of complex fistula-in-ano. Complex fistula-in-ano is difficult to treat due to the occurrence of postoperative anal incontinence and the high rate of recurrence. Seventy patients who were diagnosed with complex fistula-in-ano and underwent fistulotomy and sphincter reconstruction between October 2000 and October 2006 were analyzed in the present study. Preoperative assessment included physical examination, anorectal manometry, and anal endosonography. Appointments were scheduled every 6 months during the first and second year of treatment and every 2 years thereafter. Recurrence and incontinence were evaluated during each visit. Continence was assessed according to the Wexner continence grading scale. Anal manometry was performed 3 and 12 months after treatment and every 2 years thereafter. Anal endosonography was conducted 6 months after treatment. Fistulas were classified as medium-high trans-sphincteric in 64 patients (91.42%) and were recurrent in 22 patients (32%). Before surgery, 22 patients (32%) reported fecal incontinence, which improved after surgery in 15 cases (70%), from 6.75 to 1.88 (P Fistulotomy with sphincter reconstruction is an effective technique for the treatment of complex fistula-in-ano. Continence and anal manometry results were improved in incontinent patients and were not jeopardized in continent ones. Fistulotomy with sphincter reconstruction is an especially suitable technique for incontinent patients with recurrent fistulas.

    The long-term outcomes of 157 patients affected by Peyronie's disease (PD) who underwent penile straightening with Egydio's technique between January 2004 and December 2008 are reported.Only patients with PD who were stable for at least 6-12 months prior to surgery were enrolled in this study.Preoperative assessment included a dynamic echo colour Doppler ultrasound scan to evaluate the degree of penile deformity and the peak systolic velocity in the cavernosal arteries and an assessment of erectile function with the administration of the International Index of Erectile Function 5 (11EF-5) questionnaire.Stretched penile length was recorded pre-and postoperatively.Surgical complications,cosmesis and sexual function,patient satisfaction and postoperative erectile function were assessed postoperatively at 3 months,i year and 2 years,respectively.After a median follow-up period of 20 months (range:12-24 months),we found that mild residual curvature (12%) and glans hypoesthesia (3%) were the only causes of partial dissatisfaction.No rejection of the graft was observed.All patients recovered their ability to penetrate with no difficulty.In addition,an intraoperative average increase of 2.5 cm (range:1.7-4.1 cm) in stretched penile length was recorded,with all patients engaging in penetrative sexual intercourse.In conclusion,this procedure represents a safe and reproducible technique for the correction of penile curvature resulting from PD and yields excellent cosmetic and functional results.

    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).

    Endovascular internal carotid artery (ICA) trapping was performed to treat ruptured blood blister-like aneurysms (BBAs). The aim of this study was to evaluate the procedural risks and long-term follow-up results. The records of 11 consecutive patients with BBAs who underwent endovascular ICA trapping between 2005 and 2010 were reviewed. Clinical outcomes were assessed with modified Rankin Scale (mRS) scores. Endovascular ICA trapping was performed in 11 patients as either the primary treatment (7 patients) or the secondary treatment (4 patients) after the patient underwent other treatments. Three patients underwent superficial temporal artery (STA)-middle cerebral artery (MCA) bypass when balloon test occlusion (BTO) revealed inadequate collateral circulation. In the primary ICA trapping group (seven patients), six patients had good outcomes (mRS 0 in five, mRS 1 in one), and one patient had a poor outcome (mRS 6: dead). In the secondary ICA trapping group (four patients), two patients had good outcomes (mRS 0), and two patients had poor outcomes (mRS 4, 5). All ten of the surviving patients were clinically stable during the follow-up period (mean 39 months). A radiological follow-up of nine patients (mean 22 months) demonstrated stable occlusion, with the exception of one reopening of the ICA because of coil migration. Perfusion studies of nine patients (mean: 23 months) demonstrated no perfusion decrease. Endovascular ICA trapping is an effective and durable treatment for BBAs. (orig.)

    To report long-term results of photodynamic therapy (PDT) in young patients affected by Best vitelliform macular dystrophy (VMD) complicated by choroidal neovascularization (CNV). We evaluated a group of 30 VMD patients with confirmed mutations in the BEST1 gene. Five of these patients had been diagnosed with CNV when younger than 15 years of age and three of them were treated by PDT. After the treatment they were followed for an average period of 77 months (range 62-99). In all the treated eyes visual acuity was stable during the first year of follow-up and then slowly improved even some years after the treatment. The improvement in visual acuity was associated with the development of fibrous tissue in the macula. PDT was a safe procedure in our series of pediatric patients with VMD complicated by CNV. It was followed by a CNV regression and a consequent improvement in visual acuity which continued to progress even several years after the treatment.

    Surgical nerve root decompression is rarely needed in the treatment of cervicobrachial neuralgia. In patients with prolonged and resistant pain or neurological deficits, or when signs of associated spinal cord suffering have been found, various surgical procedures can be used, but is most cases the disco-arthro-radicular conflict can be solved by the anterior approach with or without bone graft. This review of long-term résults in a series of 122 patients operated upon and re-examined more than 3 years later shows that the radicular symptoms were relieved in 95% of the cases. Evaluation of anatomical results did not reveal any instability or aggravation of discarthrosis at the site of surgery. However, in 30% of the cases disc degeneration was increased in the over- and underlying levels but without recurrence of clinical symptoms; 4% of the patients in this series were reoperated upon for this aggravated or de novo disc disease. The authors underline the importance of a thorough radioanatomical examination not only to decide whether or not a "soft hernia" or an arthrotic hypertrophy should be operated, but also to evaluate the extent of the decompressive operation to be performed.

    Full Text Available AIM: To evaluate the degree of influence that periportal fibrosis has on clinical development and the long term results of surgical treatment on patients with hepatic-splenic schistosomiasis with previous gastrointestinal hemorrhages. METHODS: During the period of 1992-1998, 111 patients underwent surgical treatment for the treatment of hepatic-splenic schistosomiasis with previous gastrointestinal hemorrhages. The degree of fibrosis was classified as: degree I - the portal spaces show a rich increase of young connective cells, a slight collagen production and a varying presence of inflammatory infiltrate. The periportal blade unchangeable (29/111; degree II - there is an expansion of the connective tissue with the emission of radial collagen septa, producing a star shaped aspect (38/111; degree III - the connective septa form bridges with other portal spaces or with the vein, with evident angiomatoid neo-formation (44/111. CONCLUSION: The patients with periportal fibrosis degree I present recurrent hemorrhages statistically less than patients with periportal fibrosis degrees II and III, and that the intensity of the periportal fibrosis is not the only pathophysiological factor of the esophageal varices, gastric varices, prevalence of post-operative portal vein thrombosis and hematological and biochemical alterations of the patients with pure mansoni schistosomiasis.

    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 ({sup 137}Cs) transferred from soil to plants that are consumed by residents. Thus, radioecology research efforts have been focused on removing {sup 137}Cs from soil and/or reducing its uptake into vegetation. Most effective was addition of potassium (K) to soil that reduces {sup 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 {sup 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{sup -1} lead to a {sup 137}Cs concentration in drinking-coconut meat that is 34, 22, 10, and about 4% of original concentration, respectively. Concentration of {sup 137}Cs remains low 8-10 y after K is last applied. An explanation for this unexpected result is discussed.

    Full Text Available Objective: To evaluate the effect of long term use of doxycycline in IPF patients. Materials and Methods: Patients of IPF, selected randomly from out patient services and diagnosed on the basis of HRCT chest, were put on doxycycline in an open prospective trial. They were followed up with monitoring of subjective well being along with measurement of pulse rate and arterial oxygen saturation at rest and after a fixed and certain exercise, forced vital capacity, six minutes walk test, St Georges Respiratory questionnaire, and serial chest X-rays. Results: Out of seven patients put on doxycycline, six of them continued the drug for a mean period of 531.43 (± 328.88 days. All the patients tolerated the drug well and had shown uniform subjective and overall objective improvement in all the parameters concerned; the change in the radiological parameter being statistically significant. Conclusion: Doxycycline merits an appropriate clinical trial in the management of idiopathic pulmonary fibrosis. This widely used and relatively safe drug can add a new dimension to the therapeutic regimen. However, further in-depth studies will be required to evaluate its role in the management of IPF.

    To analyze the long-term results and to evaluate the efficacy of a dual expandable stent for the treatment of malignant colorectal strictures. Under the fluoroscopic guidance, stents were placed in 60 patients with malignant colorectal strictures. A dual stent consists of two stents, the outer stent was placed into the stricture which was followed by coaxial placement of the inner bare stent. Technical and clinical success rates, complications, patient survival and stent patency during the follow-up period were evaluated in this study. Stent placement was technically successful in 57 of 60 patients (95%). Of them, obstructive symptoms resolved within two days in 12/12 (100%) patients in the preoperative group and in 36/45 (80%) patients in the palliative group. Complications associated with this procedure were perforation (n = 5), migration (n = 3), and tumor overgrowth (n = 2). Each of the six patients in the preoperative group underwent conventional laparotomy and laparoscopic surgery, respectively. The mean interval between stent insertion and surgery was nine days. In the palliative group, the median survival was 159 days (mean; 235) and the median patency of stent was 116 days (mean; 185). 1-month, 3-month, 6-month, 12-month and 24-month stent patency were 75%, 60%, 27%, 13% and 7%, respectively. Insertion of a dual expandable nitinol stent into malignant colorectal obstruction is a safe and effective procedure for the palliative treatment of malignant colorectal obstruction. This procedure is also effective for preoperative decompression.

    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.

    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.

    Objectives: The objective of this study was to examine if burnout and psychosocial factors predicted long-term sickness absence (>2 weeks) at work unit level. Methods: Data were collected prospectively at 82-work units in human services (PUMA cohort, PUMA: Danish acronym for Burnout, Motivation...... and Job satisfaction) followed up during the proceeding 18 months regarding onset of long-term sickness absence. Questionnaire data regarding burnout and psychosocial factors were aggregated at work unit level. We used Poisson regression models with psychosocial factors and burnout as predictors of long......-term sickness absence for more than 18 months based on data from a national absence register. Results: Long-term sickness absence was predicted by psychosocial factors and by burnout at work unit level. Conclusion: To reduce sickness absence, organizations within human services should improve the psychosocial...

    This article discussed the results of a bottom-up analysis of Mexico's energy markets which was conducted using an energy and power evaluation program. The program was used to develop energy market forecasts to the year 2025. In the first phase of the study, dynamic optimization software was used to determine the optimal, least-cost generation system expansion path to meet growing demand for electricity. A separate model was used to determine the optimal generating strategy of mixed hydro-thermal electric power systems. In phase 2, a nonlinear market-based approach was used to determine the energy supply and demand balance for the entire energy system, as well as the response of various segments of the energy system to changes in energy price and demand levels. Basic input parameters included information on the energy system structure; base-year energy statistics; and, technical and policy constraints. A total of 14 scenarios were modelled to examine variations in load growth, sensitivities to changes in projected fuel prices, variations in assumed natural gas availability, system reliability targets, and the potential for additional nuclear capacity. Forecasts for the entire energy system were then developed for 4 scenarios: (1) reference case; (2) limited gas scenario; (3) renewable energy; and (4) additional nuclear power generation capacity. Results of the study showed that Mexico's crude oil production is projected to increase annually by 1 per cent to 2025. Imports of petroleum products resulting from the country's rapidly growing transportation sector will increase. Demand for natural gas is expected to outpace projected domestic production. The long-term market outlook for Mexico's electricity industry shows a heavy reliance on natural gas-based generating technologies. It was concluded that alternative results for a constrained-gas scenario showed a substantial shift to coal-based generation and associated effects on the natural gas

    Full Text Available 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.

    To analyse the long-term results of surgical removal of plaque-like diabetic foveal hard exudates. In this retrospective, interventional, non-randomized, controlled study, vitrectomy and excision of submacular hard exudates was performed on 11 eyes of 11 patients with plaque-like hard exudates. The mean preoperative LogMAR best corrected visual acuity (BCVA) and exudate diameter were 1.35+/-0.3 and 1.19 disks (range, 0.5-1.8), respectively. In the control group, which consisted of 10 eyes of 7 patients who refused the surgery, baseline mean BCVA and exudate diameter were 1.06+/-0.2 and 1.2 disks (range, 0.7-2.0), respectively. Main outcome measures included BCVA, fundus photography, and surgical complications. The mean follow-up was 39.1+/-3.2 months for the study group and 32.5+/-3.6 months for the control group. In the study group, BCVA improved in 8 (73%) eyes at the final examination. The mean final BCVA was 1.08+/-0.4 (P=0.021). Macular oedema and exudates resolved completely in all eyes. In the control group, final LogMAR visual acuity declined to 1.53+/-0.1 (P=0.005). Macular pigment epithelium atrophy or scar formation was observed in 7 (64%) eyes in the study group and in all eyes in the control group. Surgical excision of plaque-like foveal hard exudates resulted in better anatomical and functional outcome when compared to observation alone.

    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.

    Full Text Available Background and objective: Surgery was considered for years the standard treatment for all stages of liver hydatid cysts (LHC. Percutaneous treatment has becomes a fast, reliable and more efficient method in selected cases. The purpose of this study is to evaluate the effectiveness of percutaneous treatment of LHC on the basis of our department long-term results. Patients and Methods: This study includes all patients who benefited from percutaneous treatment for LHC from December 1998 to April 2012. Puncture aspiration, injection, and re-aspiration (PAIR were used for hydatid cysts smaller than 6 cm. Larger cysts, infected cysts and those with biliary fistula were treated by puncture associated to drainage (PA-PD. Absolute alcohol was used as sclerosing agent. Reduction of the size of the cyst more than 50%, pseudo-tumour echo pattern and disappearance of the cyst at the follow-up were retained as criteria of treatment efficacy. Results: Two hundred thirty patients (136 female and 94 male; mean age: 35 years old with 278 LHC underwent percutaneous treatment. Mean initial cyst diameter was 76.8 mm [20-180 mm]. According to Gharbi’s classification, types I and II LHC accounted for 74% and 25% respectively. Fourteen patients (6% presented with an infected cavity and 27 patients (12% had a biliary fistula at diagnosis (12%. PA-PD was initially performedin 23 patients. No mortality, abdominal dissemination, or tract seeding occurred. Minor complications like urticaria, cutaneous rash and fever were reported in 24 patients (10%. One case of anaphylactic shock was reported with good evolution. Mean hospitalization time was 3 days ± 1.5 for uncomplicated cases and 16.5 days± 4.2 for complicated cases. 229 out of 230 patients were cured, whereas one recurrence has been reported. Conclusion: Percutaneous treatmentis efficient and safe and offers complete cure in selected patients with the advantage of short hospitalization.

    AIM: Achalasia is the best known primary motor disorder of the esophagus in which the lower esophageal sphincter(LES) has abnormally high resting pressure and incomplete relaxation with swallowing. Pneumatic dilatation remains the first choice of treatment. The aims of this study were to determine the long term clinical outcome of treating achalasia initially with pneumatic dilatation and usefulness of pneumatic dilatation technique under endoscopic observation without fluoroscopy.METHODS: A total of 65 dilatations were performed in 43patients with achalasia [23 males and 20 females, the mean age was 43 years (range, 19-73)]. All patients underwent an initial dilatation by inflating a 30 mm balloon to 15 psi under endoscopic control. The need for subsequent dilatation was based on symptom assessment. A 3.5 cm balloon was used for repeat procedures.RESULTS: The 30 mm balloon achieved a satisfactory result in 24 patients (54%) and the 35 mm ballon in 78% of the remainder (14/18). Esophageal perforation as a short-term complication was observed in one patient (2.3%). The only late complication encountered was gastroesophageal reflux in 2 (4%) patients with a good response to dilatation. The mean follow-up period was 2.4 years (6 mo - 5 years). Of the patients studied, 38 (88%) were relieved of their symptoms after only one or two sessions. Five patients were referred for surgery(one for esophageal perforation and four for persistent or recurrent symptoms). Among the patients whose follow up information was available, the percentage of patients in remission was 79% (19/24) at 1 year and54% (7/13) at 5 years.CONCLUSION: Performing balloon dilatation under endoscopic observation as an outpatient procedure is simple, safe and efficacious for treating patients with achalasia and referral of surgical myotomy should be considered for patients who do not respond to medical therapy or individuals that do not desire pneumatic dilatations.

    Extralevator abdominoperineal resection (APR) for low rectal cancer has been adopted by centers to improve oncological outcome. The present study aimed to investigate oncological results, wound complications, and quality of life (QoL). Patients who underwent extralevator APR for rectal cancer between 2007 and 2011 were identified retrospectively. QoL status was assessed using the European Organisation for Research and Treatment of Cancer (EORTC) QLQ-CR30 and CR29 questionnaires. Thirty laparoscopic (n = 7) or open (n = 23) extralevator APRs were performed in 17 male and 13 female patients. The mortality was zero; circumferential margin involvement occurred in two cases (6.7 %); and there was no bowel perforation. No local recurrence was noted after a median follow-up of 28.3 months; however, six patients died, and eight developed distant metastases. Perineal wound complications were found in 46.6 % of patients, and all were managed conservatively. Fifty percent of the patients reported persistent perineal pain at the follow-up exam. QoL was assessed 7 to 46 months after surgery, and the global health status (70.6) was comparable to the EORTC reference group and published conventional APR series. The QLQ-CR29 module revealed high mean symptom scores for urinary frequency (48.1), incontinence (30.5), and impotence (79.1). Extralevator APR can control local recurrence but not distant metastases of low rectal cancer. The extended perineal resection appears not to decrease general QoL, but it results in a high rate of perineal wound complications. Genitourinary functions are often impaired, even in the long term, and further improvements to the technique must seek to reduce genitourinary harm.

    This study aimed to evaluate the long-term follow-up results of V-Y tendon plasty with fascia turndown, for repairing chronic Achilles tendon ruptures. Seventeen patients (12 males, 5 females), who were diagnosed with chronic Achilles tendon rupture and met the inclusion criteria, were included in the study. These patients received treatment by means of V-Y tendon plasty with fascia turndown from January 1995 to December 2001. Clinical outcomes of the patients were assessed by using isokinetic strength testing, questioning the patient regarding residual discomfort, pain, or swelling and having the ability to perform heel rises and using American Orthopaedic Foot & Ankle Society's (AOFAS's) Ankle-Hind Foot Scale score. Mean follow-up duration was 16 years (13-18 years). Mean time from the injury to operative treatment was 7 months. Mean operative defect of Achilles tendon in neutral position after debridement was 6 cm. During the follow-up, the mean calf atrophy was 3.4 cm. The mean 30 degrees/s plantarflex and 120 degrees/s plantarflex peak torques were 89 and 45 Nm, respectively. The mean 30 degrees/s plantarflex peak torque deficiency was 16%. The mean 120 degrees/s plantarflex peak torque deficiency was 17%. The average peak torque deficiency was 17%. The pre- and postoperative mean AOFAS Ankle-Hindfoot Scale scores were 64 and 95, respectively. No patient had a rerupture. Superficial wound infection was treated with oral antibiotic therapy in 2 patients (11%). The V-Y tendon plasty with fascia turndown for repairing chronic Achilles tendon ruptures yielded results comparable with the literature regarding clinical outcomes. This method did not require synthetic materials for augmentation and was an economic alternative compared to other repair methods. Level III, retrospective comparative study. © The Author(s) 2016.

    Peritoneal dialysis as a mode of renal replacement therapy still has not been embraced widely as an alternative to hemodialysis. Furthermore, there is marked variability in peritoneal dialysis catheter insertion techniques and perioperative management within the United States. After the publication of best-demonstrated practices for peritoneal dialysis catheter placement, the utilization of peritoneal dialysis has increased significantly at our institution. We detail the long-term success of peritoneal dialysis catheter placement after the adoption of best-demonstrated practices. Retrospective chart review was performed on all patients who underwent laparoscopic peritoneal dialysis catheter placement using the best-demonstrated practice technique from January 2005 through December 2015. Preoperative patient demographic information, intraoperative variables, 30-day morbidity and mortality, and long-term catheter durability outcomes were investigated. A total of 457 patients met inclusion criteria. Four (0.9%) patients experienced an immediate postoperative complication requiring return to the operating room. There were no perioperative mortalities. A total of 298 (65.2%) patients were available for long-term follow-up; 221 (74.2%) patients are still alive, 76 (25.6%) patients are still undergoing peritoneal dialysis, 63 (21.1%) patients transitioned from peritoneal dialysis to hemodialysis, and 88 (29.5%) patients have undergone kidney transplantation. Based on Kaplan-Meier survival plots, 30% of patients will transition from peritoneal dialysis to hemodialysis after 5.5 years of peritoneal dialysis and the median time from commencing peritoneal dialysis to kidney transplantation is 5.6 years. Based on our institutional data, the adoption of best-demonstrated practices should provide long-term and reliable access to the peritoneal cavity. We recommend the adoption of these techniques to facilitate long-term peritoneal dialysis catheter survival. Copyright © 2017

    Full Text Available Abstract Although there is a clear trend toward internal fixation for ankle arthrodesis, there is general consensus that external fixation is required for cases of posttraumatic infection. We retrospectively evaluated the technique and clinical long term results of external fixation in a triangular frame for cases of posttraumatic infection of the ankle. From 1993 to 2006 a consecutive series of 155 patients with an infection of the ankle was included in our study. 133 cases of the advanced "Gächter" stage III and IV were treated with arthrodesis. We treated the patients with a two step treatment plan. After radical debridement and sequestrectomy the malleoli and the joint surfaces were resected. An AO fixator was applied with two Steinmann-nails inserted in the tibia and in the calcaneus and the gap was temporary filled with gentamicin beads as the first step. In the second step we performed an autologous bone graft after a period of four weeks. The case notes were evaluated regarding trauma history, medical complaints, further injuries and illnesses, walking and pain status and occupational issues. Mean age at the index procedure was 49.7 years (18-82, 104 patients were male (67,1%. Follow up examination after mean 4.5 years included a standardised questionnaire and a clinical examination including the criteria of the AO-FAS-Score and radiographs. 92,7% of the cases lead to a stable arthrodesis. In 5 patients the arthrodesis was found partly-stable. In six patients (4,5% the infection was not controllable during the treatment process. These patients had to be treated with a below knee amputation. The mean AOFAS score at follow up was 63,7 (53-92. Overall there is a high degree of remaining disability. The complication rate and the reduced patient comfort reserve this method mainly for infection. Joint salvage is possible in the majority of cases with an earlier stage I and II infection.

    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.

    To evaluate the long-term effectiveness and safety of the adjustable transobturator male system (ATOMS(®) , Agency for Medical Innovations A.M.I., Feldkirch, Austria) in a European-wide multicentre setting. In all, 287 men with stress urinary incontinence (SUI) were treated with the ATOMS device between June 2009 and March 2016. Continence parameters (daily pad test/pad use), urodynamics (maximum urinary flow rate, voiding volume, residual urine), and pain/quality of life (QoL) ratings (visual analogue scale/Leeds Assessment of Neuropathic Symptoms and Signs, International Consultation on Incontinence Questionnaire-Short Form [ICIQ-SF]/Patient Global Impression of Improvement [PGI-I]) were compared preoperatively and after intermediate (12 months) as well as after individual maximum follow-up. Overall success rate, dry rate (ATOMS devices are still functioning; 56 (20%) were removed, the most common reason being local titanium intolerance (41%) and leak/dysfunction (30%). The operating time and continence outcome varied between port generations. In this regard the latest port generation (silicone-covered scrotal port) was superior to its predecessors. Primary implantation (P = 0.002), good physical health (P = 0.001), and no history of radiotherapy (P ATOMS device is safe and shows high treatment efficacy and patient satisfaction in the largest cohort study to date. The latest generation, with its pre-attached silicone-covered scrotal port, is superior to its predecessors. Significantly better results were achieved with primary implantation and in those without a history of radiotherapy. © 2016 The Authors BJU International © 2016 BJU International Published by John Wiley & Sons Ltd.

    We present the results of an expanded, long-term radial velocity search (25 years) for evidence of binarity in a sample of seven bright proto-planetary nebulae (PPNe). The goal is to investigate the widely held view that the bipolar or point-symmetric shapes of planetary nebulae (PNe) and PPNe are due to binary interactions. Observations from three observatories were combined from 2007 to 2015 to search for variations on the order of a few years and then combined with earlier observations from 1991 to 1995 to search for variations on the order of decades. All seven show velocity variations due to periodic pulsation in the range of 35–135 days. However, in only one PPN, IRAS 22272+5435, did we find even marginal evidence for multi-year variations that might be due to a binary companion. This object shows marginally significant evidence of a two-year period of low semi-amplitude, which could be due to a low-mass companion, and it also displays some evidence of a much longer period of >30 years. The absence of evidence in the other six objects for long-period radial velocity variations due to a binary companion sets significant constraints on the properties of any undetected binary companions: they must be of low mass, ≤0.2 M ⊙, or long period, >30 years. Thus the present observations do not provide direct support for the binary hypothesis to explain the shapes of PNe and PPNe and severely constrains the properties of any such undetected companions.

    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.

    Full Text Available Los colgajos libres resuelven problemas complejos. En situaciones en donde existe gran pérdida de tejidos u otros métodos reconstructivos han fracasado se puede lograr restablecer la forma y la función utilizándolos. En este trabajo se presentan cinco pacientes en los que se usaron once colgajos libres (2 por paciente en cuatro casos, tres en otro y sus resultados a largo plazo con un mínimo de seguimiento de 7 años y un máximo de 17 años. Las indicaciones para utilizar más de un colgajo libre en un paciente son: reponer un primer colgajo perdido, por complejidad del problema, por experiencia del cirujano o por deseo expreso del paciente para una reconstrucción similar. En nuestra serie, la complejidad del problema fue la principal indicación de usar este método doble y triple. Cuatro pacientes recibieron los colgajos en los miembros inferiores y uno en la cara. Las etiologías encontradas fueron: secuelas de quemaduras en dos casos, secuelas posttraumáticas en otros dos y secuelas postquirúrgicas y de mielomeningocele en uno. Se utilizaron cuatro colgajos de dorsal ancho, cinco escapulares, uno de peroné y uno de gracilis. El seguimiento a largo plazo nos permite mostrar la gran adaptabilidad de los colgajos libres, su resistencia y su valor como procedimiento reconstructivo de primera opciónFree flaps are useful to solve complex problems. Whenever there is an extensive loss of tissues or when other reconstructive methods have failed, they may provide the means to restore shape and function. This paper deals with five patients in whom eleven free flaps were used (two in four patients and three in one more case to solve complex problems. Furthermore, long-term results are reported, with follow-up ranging from 7 to 17 years Indications to use more than one free flap in a patient are: replacing a first flap that was lost, a highly complex problem, the surgeon’s expertise, or when the patient wish for a similar reconstruction.

    Long-term antiviral prophylaxis is required to prevent hepatitis B recurrence for patients with chronic hepatitis B after liver transplantation. We determined the long-term outcome of 265 consecutive chronic hepatitis B liver transplant recipients treated with entecavir monotherapy without hepatitis B immune globulin. Viral serology, viral load, and liver biochemistry were performed at regular intervals during follow-up. The median duration of follow-up was 59 months. The cumulative rates of hepatitis B surface antigen (HBsAg) seroclearance were 90% and 95% at 1 and 5 years, respectively. At 1, 3, 5, and 8 years, 85%, 88%, 87.0%, and 92% were negative for HBsAg, respectively, and 95%, 99%, 100%, and 100% had undetectable hepatitis B virus (HBV) DNA, respectively. Fourteen patients remained persistently positive for HBsAg, all of whom had undetectable HBV DNA. There was no significant difference in liver stiffness for those who remained HBsAg-positive compared to those who achieved HBsAg seroclearance (5.5 versus 5.2 kPa, respectively; P = 0.52). The overall 9-year survival was 85%. There were 37 deaths during the follow-up period, of which none were due to hepatitis B recurrence. Long-term entecavir monotherapy is highly effective at preventing HBV reactivation after liver transplantation for chronic hepatitis B, with a durable HBsAg seroclearance rate of 92%, an undetectable HBV DNA rate of 100% at 8 years, and excellent long-term survival of 85% at 9 years.

    2012-10-01

    Full Text Available Abstract Background Only protein diet has been used successfully to prevent loss of lean body mass first in post-surgical and then in obese patients. We studied overweight and obese patients receiving short treatments of an exclusively protein-based nutritional solution as 24-hour enteral infusion. Methods 19,036 patients (age 44.3 ± 13, M:F = 2:5 with an initial body mass index of 36.5 ± 7.1 underwent 10-day cycles of enteral nutrition through a fine nasogastric tube. The nutritional solution consisted solely of 50–65 g of proteins, plus vitamins and electrolytes. The 24-hour infusion was controlled with a small portable pump. Before and after each 10-day cycle body composition was checked with a Handy 3000 impedance analyzer. At the onset of treatment, average fat mass was 40.9 ± 12.8 kg while body cell mass was 42.7 ± 7.2 kg in males and 27.4 ± 4.6 kg in females. Results After an average of 2.5 cycles the patients lost 10.2 ± 7.0 kg of body weight, 5.8 ± 5.5 kg of fat mass and 2.2 ± 3.3 kg of body cell mass. No significant adverse effects were recorded except asthenia and constipation which were easily controlled with therapy. Long-term results were obtained from 15,444 patients and after an average of 362 ± 296 days we found a mean weight regain of 15.4%. Conclusion Ketogenic Enteral Nutrition treatment of over 19,000 patients induced a rapid 10% weight loss, 57% of which was Fat Mass. No significant adverse effects were found. The treatment is safe, fast, inexpensive and has good one-year results for weight maintenance.

    Purpose: To demonstrate the efficacy and long-term results of the single-session ethanol sclerotherapy in simple renal cysts. Materials and methods: Ninety-eight cysts in 97 patients (range: 18-76 years; mean age, 54 years) were included in the study. Indications were determined as flank pain in 74, hydronephrosis in 12, hypertension in 8, patient reassurance due to increasing cyst size in three patients. Mean follow-up period was 24.4 months. Procedures were performed with the guidance of fluoroscopy and ultrasonography at all times using 5-7 Fr pigtail catheters. After the cystogram that was obtained in all cases, 95% ethanol with a volume of 30-40% of the cyst volume was used as a sclerosing agent on an outpatient basis. Maximum volume of the injected ethanol was 200 ml. Follow-up examinations were performed 1, 3, 6 and 12 months after the procedure and once every year thereafter. Results: Average cyst volume reduction was 93% at the end of the first year. The cysts disappeared completely in 17 (17.5%) patients. After the procedure, in 67 (90%) patients improvement in flank pain was noted. Sixty-one (82%) patients were free of pain and in 6 (8%) of them the pain decreased. Normotension was obtained in 7 (87.5%) of the 8 hypertensive patients and no hydronephrosis was detected in 10 (83.3%) of the 12 patients after the procedure. Second intervention was required in 2 (2%) patients due to recurrence of cysts and related symptoms. One (1%) patient had small retroperitoneal hematoma that resolved spontaneously and in another (1%) patient spontaneous hemorrhage was detected into the cyst 1 year after the procedure. No other complication was detected during the procedure and follow-up. Conclusion: Percutaneous treatment of simple renal cysts with single-session sclerotherapy is a safe, effective and minimally invasive procedure and can be used as an alternative to multiple-session sclerotherapy with comparable results. High volume, up to 200 ml ethanol can be used

    years were 48.6%, 22.8%, and 75.1%, respectively. Conventional radiotherapy was effective in preventing tumor growth of pituitary adenomas. But the effect of reducing hormone levels in functioning adenomas appeared to require several years after radiotherapy in most cases. Because hypopituitarism occurs in the late period after radiotherapy, long-term follow-up is necessary and mandatory. (author)

    AIM: To evaluate the long-term efficacy and safety of endoscopic obliteration with Histoacryl(R) for treatment of gastric variceal bleeding and prophylaxis. METHODS: Between January 1994 and March 2010 at SoonChunHyang University Hospital, a total of 127 patients with gastric varices received Histoacryl(R) injections endoscopically. One hundred patients underwent endoscopic Histoacryl(R) injections because of variceal bleeding, the other 27 patients received such injections as a prophylactic procedure. RESULTS: According to Sarin classification, 56 patients were GOV1, 61 patients were GOV2 and 10 patients were IGV. Most of the varices were large (F2 or F3, 111 patients). The average volume of Histoacryl(R) per each session was 1.7 ± 1.3 cc and mean number of sessions was 1.3 ± 0.6. (1 session-98 patients, 2 sessions-25 patients, ≥ 3 sessions-4 patients). Twenty-seven patients with high risk of bleeding (large or fundal or RCS+ or Child C) received Histoacryl(R) injection as a primary prophylactic procedure. In these patients, hepatitis B virus was the major etiology of cirrhosis, 25 patients showed GOV1 or 2 (92.6%) and F2 or F3 accounted for 88.9% (n = 24).The rate of initial hemostasis was 98.4% and recurrent bleeding within one year occurred in 18.1% of patients.Successful hemostasis during episodes of rebleeding was achieved in 73.9% of cases. Median survival was 50 mo (95% CI 30.5-69.5). Major complications occurred in 4patients (3.1%). The rebleeding rate in patients with hepatocellular carcinoma or GOV2 was higher than in those with other conditions. None of the 27 subjects who were treated prophylactically experienced treatment-related complications. Cumulative survival rates of the 127 patients at 6 mo, 1, 3, and 5 years were 92.1%, 84.2%,64.2%, and 45.3%, respectively. The 6 mo cumulative survival rate of the 27 patients treated prophylactically was 75%.CONCLUSION: Histoacryl(R) injection therapy is an effective treatment for gastric varices and also

    The LTDE-SD experiment, (Long Term Sorption Diffusion Experiment) aimed at increasing the scientific knowledge of sorption and diffusion under in situ conditions and to provide data for performance and safety assessment calculations. Performance and results of the in situ experiment phase are presented in the report. In total, 21 radionuclide trace elements and one stable trace element were injected, circulated and sampled for approx6.5 months in a closed borehole section. The trace elements represented non-sorbing tracers and sorbing tracers for which the sorption was dominated by a cation exchange mechanism, a surface complexation mechanism, or dependent on an electrochemical reduction in order to reach the tetravalent state (oxidation state IV) considered very strongly sorbing. The borehole section in contact with the tracer labelled groundwater consisted in part of a natural fracture surface and a borehole section in the unaltered matrix rock, devoid of natural fractures. Water samples were regularly extracted and analysed for trace element concentration and a few ion exchange speciation and filtered samplings were also conducted. Independent colloid filtering and chemical speciation calculations were performed in support the evaluation. Sorption was demonstrated for a series of elements present in the experiment. The amounts lost of the different respective tracers from the aqueous phase follow very well the general understanding of the relative sorption strength of the tracers, as inferred from e.g. batch sorption experiments and dynamic in situ tracer experiments. The chemical speciation calculations of the different tracers were in line with the results of the ion exchange speciation performed during the experiment. With the exception of UO{sub 2} 2+ carbonate complexes formed, no strong indications were obtained that aqueous complexation prevents adsorption under the chemical conditions of the experiment. The 20 nm filtered sampling indicated that

    To assess the long-term results of protocol-based interstitial pulsed-dose-rate (PDR) brachytherapy as reirradiation combined with simultaneous chemotherapy and interstitial hyperthermia in selected patients with recurrent head and neck tumors. A total of 104 patients with biopsy-proven recurrent head and neck cancer were treated with interstitial PDR brachytherapy. Salvage surgery had also been undergone by 53/104 (51 %) patients (R1 or R2 resection in > 80 % of patients). Salvage brachytherapy alone was administered in 81 patients (78 %), with a median total dose of 56.7 Gy. Salvage brachytherapy in combination with external beam radiotherapy (EBRT) was performed in 23/104 patients (32 %), using a median total dose of D{sub REF} = 24 Gy. Simultaneously to PDR brachytherapy, concomitant chemotherapy was administered in 58/104 (55.8 %) patients. A single session of interstitial hyperthermia was also used to treat 33/104 (31.7 %) patients. The analysis was performed after a median follow-up of 60 months. Calculated according to Kaplan-Meier, local tumor control rates after 2, 5, and 10 years were 92.5, 82.4, and 58.9 %, respectively. Comparing results of salvage PDR brachytherapy with or without simultaneous chemotherapy, the 10-year local control rates were 76 vs. 39 % (p= 0014), respectively. No other patient- or treatment-related parameters had a significant influence on treatment results. Soft tissue necrosis or bone necrosis developed in 18/104 (17.3 %) and 11/104 (9.6 %) patients, respectively, but only 3 % of patients required surgical treatment. PDR interstitial brachytherapy with simultaneous chemotherapy is a very effective and, in experienced hands, also a safe treatment modality in selected patients with head and neck cancer in previously irradiated areas.

    To observe long-term clinical outcomes for patients with early-stage breast cancer treated with forward intensity-modulated radiation therapy (IMRT), including local control and clinical toxicities. We retrospectively analyzed a total of 214 patients with stage I-II breast cancer who were treated with breast conserving surgery followed by adjuvant breast radiation therapy between 2001 and 2008. All patients were treated using forward IMRT. The whole breast was irradiated to a dose of 50 to 50.4 Gy followed by an 8 to 12 Gy electron boost to the surgical bed. The median age was 46 years (range, 21 to 82 years) and the medial follow-up time was 7.3 years (range, 2.4 to 11.7 years). Stage T1 was 139 (65%) and T2 was 75 (35%), respectively. Ipsilateral breast recurrence was observed in 3 patients. The 5- and 10-year local control rates were 99.1% and 97.8%, respectively. The cosmetic outcome was evaluated according to the Harvard scale and 89.4% of patients were scored as excellent or good. The whole breast radiation therapy as an adjuvant treatment using a forward IMRT technique showed excellent long-term local control as well as favorable outcomes of toxicity and cosmesis.

    A double-blind, placebo-controlled study with a subsequent open-label phase was conducted in 354 patients with Parkinson's disease (PD) and motor fluctuations under individually adjusted therapy with levodopa. During the double-blind phase 174 patients received pramipexole and 180 placebo. In agreement with previous studies, pramipexole treatment improved UPDRS sum scores of parts II and III by 30% and off times by approximately 2.5 hours per day. Differences between the treatment groups became significant at a daily dose of 0.75 mg of pramipexole dihydrochloride. We, furthermore, performed post hoc analyses with respect to resting tremor and depression. Patients with pronounced resting tremor derived a clear benefit from pramipexole treatment compared with placebo. In addition, pramipexole significantly improved the subitems motivation/initiative and depression in a subpopulation with increased Unified Parkinson's Disease Rating Scale I scores at the time of inclusion. There were 262 patients who were subsequently enrolled into the open-label study featuring a maximum duration of up to 57 months. Statistical analysis revealed good long-term efficacy and tolerability of pramipexole. Overall, only a low prevalence of somnolence was found. In summary, this study provides additional level I evidence of the usefulness of pramipexole, suggests a particular tremorlytic and a possible antidepressant action of this compound, and addresses for the first time its efficacy and safety during long-term administration in advanced PD.

    The aim of this study was to evaluate the long-term facial nerve outcome according to management of the facial nerve in patients undergoing surgery for Fisch class C tympanojugular paragangliomas. The study population consisted of 122 patients. The infratemporal type A approach was the most common surgical procedure. The facial nerve was left in place in 2 (1.6%) of the 122 patients, anteriorly rerouted in 97 (79.5%), anteriorly rerouted with segmental resection of the epineurium in 7 (5.7%), and sacrificed and reconstructed in 15 (12.3%). One patient underwent cross-face nerve grafting. At last follow-up, House-Brackmann grade I to II was achieved in 51.5% of patients who underwent anterior rerouting and in 28.5% of those who underwent anterior rerouting with resection of the epineurium. A House-Brackmann grade III was achieved in 73.3% of patients who underwent cable nerve graft interposition. The two patients in whom the facial nerve was left in place experienced grade I and grade III, respectively. The patient who underwent cross-face nerve grafting had grade III. Gross total resection was achieved in 105 cases (86%). Management of the facial nerve in tympanojugular paraganglioma surgery can be expected to ensure satisfactory facial function long-term outcome.

    The Bernese periacetabular osteotomy is a commonly used non-arthroplasty option to treat developmental hip dysplasia in symptomatic younger patients. Predicting which hips will remain preserved and which hips will go on to require arthroplasty following periacetabular osteotomy is a major challenge. In the present study, we assessed the intermediate to long-term results following periacetabular osteotomy to demonstrate the clinical outcomes for patients with varying amounts of dysplasia and arthritis. From these results, a probability-of-failure analysis was conducted to predict the likelihood of hip preservation and to improve surgical decision-making. Of the 189 hips (in 157 patients) that were treated with periacetabular osteotomy by a single surgeon from May 1991 to September 1998, thirty-one had diagnoses other than developmental hip dysplasia and twenty-three were lost to follow-up. The remaining 135 hips (in 109 patients) were retrospectively reviewed at an average of nine years. Hips were evaluated with use of the pain subscale of the Western Ontario and McMaster Universities Osteoarthritis Index postoperatively as well as with radiographs that were made preoperatively and at one and more than five years postoperatively. Osteotomy failure was defined as a pain score of ≥10 or the need for total hip arthroplasty. One hundred and two hips (76%) remained preserved at an average of nine years, with an average Western Ontario and McMaster Universities pain score of 2.4 of 20. Thirty-three hips (24%) met the failure criteria: seventeen underwent arthroplasty at an average of 6.1 years after the osteotomy, and sixteen had a postoperative pain score of ≥10. Kaplan-Meier analysis with arthroplasty as the end point revealed a survival rate of 96% (95% confidence interval, 93% to 99%) at five years and 84% (95% confidence interval, 77% to 90%) at ten years. Complications occurred in twenty hips. Fifteen hips (11%) were treated with a subsequent arthroscopy because

    To evaluate the long-term efficacy of pain reduction by two dose fractionation schedules used for low-dose radiotherapy of painful elbow syndrome. Between February 2006 and February 2010, 199 evaluable patients were recruited for this prospective trial. All patients received low-dose orthovoltage radiotherapy. One course consisted of 6 fractions in 3 weeks. In the case of insufficient pain remission after 6 weeks, a second course was administered. Patients were randomly assigned to one of two groups to receive single doses of either 0.5 or 1.0 Gy. Endpoint was pain reduction. Pain was measured before radiotherapy, as well as immediately after (early response), 6 weeks after (delayed response) and approximately 3 years after (long-term response) completion of radiotherapy using a questionnaire-based visual analogue scale (VAS) and a comprehensive pain score (CPS). Median follow-up was 35 months (range 9-57 months). The overall early, delayed and long-term response rates for all patients were 80, 90 and 94 %, respectively. The mean VAS scores before treatment and those for early, delayed and long-term response in the 0.5- and 1.0-Gy groups were 59.6 ± 20.2 and 55.7 ± 18.0 (p = 0.46); 32.1 ± 24.5 and 34.4 ± 22.5 (p = 0.26); 27.0 ± 27.7 and 23.5 ± 21.6 (p = 0.82) and 10.7 ± 15.0 and 21.5 ± 26.9 (p = 0.12), respectively. The mean CPS values before treatment and those for early, delayed and long-term response were 8.7 ± 2.9 and 8.1 ± 3.1 (p = 0.21); 4.5 ± 3.2 and 5.0 ± 3.4 (p = 0.51); 3.9 ± 3.6 and 2.8 ± 2.8 (p = 0.19) and 1.5 ± 2.3 and 2.4 ± 3.5 (p = 0.27), respectively. No significant differences in the quality of the long-term response were found between the 0.5- and 1.0-Gy arms (p = 0.28). Low-dose radiotherapy is an effective treatment for the management of benign painful elbow syndrome. For radiation protection reasons, the dose for a radiotherapy series should not exceed 3.0 Gy.

    We conducted a retrospective descriptive study of a series of 31 consecutively presenting patients who had been implanted with the Vibrant Soundbridge middle ear hearing device. All implantations had been performed by the senior author. Three of these patients had undergone bilateral implantation, and 4 others had undergone subsequent explantation and reimplantation in response to known or suspected device failure, giving us a total of 34 ears and 38 implants. Our goal was to ascertain short- and long-term outcomes as measured by conventional audiometry (pure-tone average at 1 to 6 kHz) and long-term benefit as defined by the use or nonuse of the device. We found that at the initial activation session 2 months postoperatively, the average hearing thresholds were within 3 dB of the preoperative thresholds in all 34 ears and all 38 implants. The mean short-term gain at activation in the 38 implants was 28.1 dB. Nineteen patients (20 ears) were available for long-term evaluation, with the length of follow-up ranging from less than 1 year to 11 years (mean: 7.3). Of these 20 ears, 9 demonstrated further gain (mean: 10.8 dB) despite any natural hearing deterioration; of the remaining 11 ears, gain was unchanged in 2, diminished in 7 (mean: -3.6 dB), and gain data were unavailable in 2. In the final analysis, there were 20 user ears and 10 nonuser ears; 4 ears were lost to all follow-up. We conclude that direct-drive hearing with the Vibrant Soundbridge middle ear hearing device is beneficial and provides sustained audiometric gain. Factors that have a significant impact on patient use or nonuse include difficulty in obtaining audiologic support and the direct and indirect costs of the device. Without audiologic or financial support, some patients may choose to become nonusers and to either switch to conventional hearing aid amplification or become apathetic about hearing improvement.

    The planetary quarantine is one of the key problems of deep space exploration. Risks of the possible transfer of biological objects across interplanetary space should be necessarily assessed during space exploration. The risks associated with a possible transfer of biological objects and primarily microorganisms in interplanetary space is a priority for space studies We can assume, that on the exterior side of both unmanned and manned space stations there can be millions of microbial cells, many of which are in spore forms, the stability of which towards the unfavorable factors is extremely high. However, direct evidence to support this assumption, obtained only in recent years. “Biorisk” is an apparatus designed for conduction of space experiments focused on long-term exposition of latent stages of different forms of organism on the outer side of Russian Segment of International Space Station was developed and used in SSC RF - Institute for Biomedical Problems RAS. The purpose of this experiment is to determine the principle capability of preservation of life capacity in test-cultures of microorganisms during long-term exposure (comparable with the term of interplanetary flight) in space. The first experiment was performed using spores of bacteria (Bacillus) and fungi (Penicillium, Aspergillus and Cladosporium) housed in 3 boxes that were exposed to outer space for 7, 12 or 18 months. It was for the first time demonstrated that bacterial and fungal spores could survive an exposure to outer space during the time period comparable with the duration of a return mission to Mars. Moreover, the microbial strains proved viable and highly active. The second experiment was expanded by flying, in addition to the above spores, dormant forms of higher plants, insects, lower crustaceans and vertebrates. The 31-month experiment showed that, in spite of harsher than in the first study temperatures, some specimens remained viable and capable of further multiplication. In

    Full Text Available Everolimus, a mammalian target of rapamycin (mTOR inhibitor, has demonstrated efficacy in treating subependymal giant cell astrocytomas (SEGAs and other manifestations of tuberous sclerosis complex (TSC. However, long-term use of mTOR inhibitors might be necessary. This analysis explored long-term efficacy and safety of everolimus from the conclusion of the EXIST-1 study (NCT00789828.EXIST-1 was an international, prospective, double-blind, placebo-controlled phase 3 trial examining everolimus in patients with new or growing TSC-related SEGA. After a double-blind core phase, all remaining patients could receive everolimus in a long-term, open-label extension. Everolimus was initiated at a dose (4.5 mg/m2/day titrated to a target blood trough of 5-15 ng/mL. SEGA response rate (primary end point was defined as the proportion of patients achieving confirmed ≥50% reduction in the sum volume of target SEGA lesions from baseline in the absence of worsening nontarget SEGA lesions, new target SEGA lesions, and new or worsening hydrocephalus. Of 111 patients (median age, 9.5 years who received ≥1 dose of everolimus (median duration, 47.1 months, 57.7% (95% confidence interval [CI], 47.9-67.0 achieved SEGA response. Of 41 patients with target renal angiomyolipomas at baseline, 30 (73.2% achieved renal angiomyolipoma response. In 105 patients with ≥1 skin lesion at baseline, skin lesion response rate was 58.1%. Incidence of adverse events (AEs was comparable with that of previous reports, and occurrence of emergent AEs generally decreased over time. The most common AEs (≥30% incidence suspected to be treatment-related were stomatitis (43.2% and mouth ulceration (32.4%.Everolimus use led to sustained reduction in tumor volume, and new responses were observed for SEGA and renal angiomyolipoma from the blinded core phase of the study. These findings support the hypothesis that everolimus can safely reverse multisystem manifestations of TSC in a

    This paper describes results of a long-term investigation of a population exposed to radioactive waste release in 1949-1956 into the Techa River in the Southern Urals. Systematic measurements of radionuclide concentration in the river waters, sediments, and floodplain soils and measurements of exposure gamma dose rates as well as studies of the radionuclide composition in the contaminated areas began in the summer of 1951. As a result of the contamination, 124,000 residents were exposed to radiation and 28,100 received significant doses in terms of health effect potential. Covered results include the following: estimation of external radiation doses; content of strontium-90 in humans and estimation of radionuclide ingestion rates; age-dependent model of strontium metabolism in the human body; evaluation of doses of internal irradiation; distribution of exposed population according to accumulated doses. 11 refs; 15 figs.

    On September 25th, 1987 methadone was legalized in Austria for therapeutic use in drug addiction treatment in case of: 1. Long-term drug addiction with intravenous application of the drug, and several unsuccessful withdrawal therapies and/or 2. opiate addiction through intravenous application of the drug along with an existing HIV-1 infection. Since than, 291 patients were treated with methadone at the drug-dependency outpatient clinic of the Psychiatric Clinic of the University of Vienna. In 1990, 96 patients treated for more than one year were investigated using a standardized questionnaire. The image in which crime, prostitution, poverty, ill health all merge was broken by this decriminalization. Methadone treatment offers a first step toward social rehabilitation for drug addicts who have been living as criminals on the fringe of society.

    Transcorneal alternating current stimulation (tACS) was proposed to decrease acute death of retinal ganglion cells after optic nerve transection in rats, but it is not known if cell survival is long-term and associated with functional restoration. We therefore evaluated the effects of tACS in a rat model of optic nerve crush using anatomical, electrophysiological and behavioural measures. Rats were trained in a brightness discrimination visual task and the retinal ganglion cell number was quantified with in vivo confocal neuroimaging. Thereafter, severe optic nerve crush or sham crush was performed and rats were treated under anaesthesia either with tACS or sham stimulation immediately after the lesion and on day 3, 7, 11, 15, 19 and 23. Brightness discrimination was evaluated for 6 weeks and retinal ganglion cells were counted in vivo on post-crush days 7 and 28. In additional rats we studied the influence of tACS on bioelectrical activity. On post-lesion day 28, the tACS-treated group showed a neuronal survival of 28.2% which was significantly greater than in sham operates (8.6%). All animals with optic nerve crush were significantly impaired in brightness discrimination and did not recover performance, irrespective to which group they belonged. In accordance with this, there was no significant influence of the stimulation on EEG power spectra. In conclusion, tACS induced long-term neuronal protection from delayed retrograde cell death, but in this case of severe axonal damage tACS did not influence functional restoration and EEG signals recorded over the visual cortex.

    Full Text Available Objective. To compare efficacy and safety of nimesulide and paracetamol in treatment of patients with osteoarthritis (OA during 12 months. Material and methods. 40 women (mean age 66,8±5,1 years with knee osteoarthritis (II-III stage according to Kellgren-Lawrence having intensive pain (>40 mm on VAS were included. Group 1 pts (n=20 received nimesulide 200-100 mg/day. Group 2 pts were treated with paracetamol till 3 g/day. WOMAC was used as efficacy measure. Safety was assessed with endoscopic examination of upper gastrointestinal tract, ECG, blood pressure and ECG Holter monitoring, clinical and biochemical blood parameters. Statistical significance of differences was assessed with Student’s t-test, χ2 and Fisher exact test Results. WOMAC index decreased during treatment from 1182,7±345,9 to 698,4±351,1 for nimesulide and from 1136,4±313,8 to 1031,6±21 for paracetamol (p<0,05. There were 6 cases of gastrointestinal complications and 4 cases of hypertension development or deterioration in each group. Coronary heart disease developed or deteriorated in 4 patients receiving nimesulide but not in control group. Liver function tests did not deteriorated during treatment with nimesulide. Conclusion. Nimesulide was more effective than paracetamol in treatment of OA. But risk of cardiovascular complications development during treatment with NSAIDs requires serious attention. Nimesulide did not induced liver damage during long term treatment.

    To evaluate the short-term and long-term effects of fluoroscopically guided caudal epidural steroid injection (ESI) for the management of degenerative lumbar spinal stenosis (DLSS) and to analyze outcome predictors. All patients who underwent caudal ESI in 2006 for DLSS were included in the study. Response was based on chart documentation (aggravated, no change, slightly improved, much improved, no pain). In June 2009 telephone interviews were conducted, using formatted questions including the North American Spine Society (NASS) patient satisfaction scale. For short-term and long-term effects, age difference was evaluated by the Mann-Whitney U test, and gender, duration of symptoms, level of DLSS, spondylolisthesis, and previous operations were evaluated by Fisher's exact test. Two hundred and sixteen patients (male: female = 75:141; mean age 69.2 years; range 48{proportional_to}91 years) were included in the study. Improvements (slightly improved, much improved, no pain) were seen in 185 patients (85.6%) after an initial caudal ESI and in 189 patients (87.5%) after a series of caudal ESIs. Half of the patients (89/179, 49.8%) replied positively to the NASS patient satisfaction scale (1 or 2). There were no significant outcome predictors for either the short-term or the long-term responses. Fluoroscopically guided caudal ESI was effective for the management of DLSS (especially central canal stenosis) with excellent short-term and good long-term results, without significant outcome predictors.

    Full Text Available During odor sensing the activity of principal neurons of the mammalian olfactory bulb, the mitral and tufted cells (MTCs, occurs in repetitive bursts that are synchronized to respiration, reminiscent of hippocampal theta-gamma coupling. Axonless granule cells (GCs mediate self- and lateral inhibitory interactions between the excitatory MTCs via reciprocal dendrodendritic synapses. We have explored long-term plasticity at this synapse by using a theta burst stimulation (TBS protocol and variations thereof. GCs were excited via glomerular stimulation in acute brain slices. We find that TBS induces exclusively long-term depression in the majority of experiments, whereas single bursts (“single-sniff paradigm” can elicit both long-term potentiation and depression. Statistical analysis predicts that the mechanism underlying this bidirectional plasticity involves the proportional addition or removal of presynaptic release sites. Gamma stimulation with the same number of APs as in TBS was less efficient in inducing plasticity. Both TBS- and “single-sniff paradigm”-induced plasticity depend on NMDA receptor activation. Since the onset of plasticity is very rapid and requires little extra activity, we propose that these forms of plasticity might play a role already during an ongoing search for odor sources. Our results imply that components of both short-term and long-term olfactory memory may be encoded at this synapse.

    The City of Albuquerque, New Mexico, is interested in gaining a better understanding, both quantitative and qualitative, of the aquifer system in and around Albuquerque. Currently (2000), the City of Albuquerque and surrounding municipalities are completely dependent on ground-water reserves for their municipal water supply. This report presents the results of a long-term aquifer test conducted near the Rio Grande in Albuquerque. The long-term aquifer test was conducted during the winter of 1994-95. The City of Albuquerque Griegos 1 water production well was pumped continuously for 54 days at an average pumping rate of 2,331 gallons per minute. During the 54-day pumping and a 30-day recovery period, water levels were recorded in a monitoring network that consisted of 3 production wells and 19 piezometers located at nine sites. These wells and piezometers were screened in river alluvium and (or) the upper and middle parts of the Santa Fe Group aquifer system. In addition to the measurement of water levels, aquifer-system compaction was monitored during the aquifer test by an extensometer. Well-bore video and flowmeter surveys were conducted in the Griegos 1 water production well at the end of the recovery period to identify the location of primary water- producing zones along the screened interval. Analytical results from the aquifer test presented in this report are based on the methods used to analyze a leaky confined aquifer system and were performed using the computer software package AQTESOLV. Estimated transmissivities for the Griegos 1 and 4 water production wells ranged from 10,570 to 24,810 feet squared per day; the storage coefficient for the Griegos 4 well was 0.0025. A transmissivity of 13,540 feet squared per day and a storage coefficient of 0.0011 were estimated from the data collected from a piezometer completed in the production interval of the Griegos 1 well.

    In this paper we report the long-term optical observation of the faint soft X-ray transient SAX J1810.8-2609 from OGLE and MOA. We have focused on the 2007 outburst, and also did the cross-correlate between its optical light curves and the quasi-simultaneous X-ray observations from swift. Both the optical and X-ray light curves of 2007 outburst show multi-peak features. Quasi-simultaneous optical/X-ray luminosity shows that both the X-ray reprocessing and viscously thermal emission can explain the observed optical flux. There is a slightly X-ray delay of 0.6+-0.3 days during the first peak, while the X-ray emission lags the optical emission by ~2 days during the rebrightening stage, which suggests that X-ray reprocessing emission contributes significantly to the optical flux in the first peak, but the viscously-heated-disk origin dominates the optical flux during rebrightening. It implies variation of the physical environment of the outer disk, even the source stayed in low-hard state during the whole outburs...

    The purpose of this article is to report long-term follow-up of improved external vulvuloplasty, intravenous laser photocoagulation and local sclerotherapy treatment of primary deep venous valvular insufficiency in eight hundred and seventy-two patients from Nov. 2000 to May 2006. Patients were evaluated clinically and with duplex ultrasound at 1, 3, and 12 months, and yearly thereafter until the fifth year to assess treatment efficacy and adverse reactions. Successful occlusion of the great saphenous vein and absence of deep vein reflux on color Doppler imaging, were noted in 956 limbs of 852 cases( 1 month follow-up), 946 limbs of 842 cases (6 month to 1 year follow-up), 717 of 626 (1~2 year follow-up), 501 of 417 (2~3 year follow-up), 352 of 296 (3~5year follow-up), 142 of 106 (5 year follow-up) after initial treatment. The cumulative total number of recurrence of reflux was fifteen cases. The respective competence rate was 95.18%, 96.23%, 94.23%, 95.25%, 94.23% and 94.12%. Of note, all recurrence occurred before 9 months, with the majority noted before 3 months. Bruising was noted in 0.7% of patients, tightness along the course of treated vein in 1.0% of limbs. There have been no paresthesia of cases, skin burns and deep vein thrombosis.

    1977-01-01

    Unilateral application of ascaris extract on segment bronchus as the influence of contralateral vagus blockade on reflex bronchoconstriction was studied on four boxer dogs in a first group (A) of experiments: ascaris extract was applied in liquid form directly through a catheter into the right segment bronchus. This application was repeated after contralateral vagus blockade and once more after its lavage. All the animals showed an increase of airway resistance under local application of ascaris extract which could not be avoided by contralateral central vagus blockade. In the second group (B) isolation of unilateral vagus for reproducible performance of blockade as a long-term model was investigated in three boxer dogs for 7 weeks and the influence of this method of unilateral vagus blockade on exposure to allergen aerosol was studied. The unilateral blockade of the nerve vagus was again always successful in decreasing the reflex bronchoconstriction following allergen inhalation. The effect of unilateral section of nervus vagus 3 weeks after this vagotomy was tested on two boxer dogs. Reflex bronchoconstriction following ascaris extract inhalation can be avoided by unilateral section of the nervus vagus the first time after section. Three weeks after this unilateral vagotomy, the reflex bronchoconstriction becomes managed by the remaining vagus trunk to the same degree as observed by bilateral intact vagi.

    The purpose of this study was to determine the long-term safety of transplanting human fetal neuroretinal cells (14 to 18 week gestational age) into a series of patients with advanced retinitis pigmentosa (RP). After obtaining informed consent, both hosts and mothers of donors were screened for transmissible diseases. Pre- and postoperative clinical exams, visual acuity, electroretinograms, and fluorescein angiograms were performed and visual field testing was attempted in each case. Surgically, an anterior approach through pars plana ciliaris was used. A retinotomy was performed in the paramacular area and a two-function cannula was introduced into the subretinal space to deliver a suspension of donor cells. The cell suspension carried approximately 4000 cells/microl; the volume injected did not exceed 150 microl. The patients were examined for periods ranging from 12 to 40 months posttransplantation. To date, no evidence of inflammation, infection, or overt rejection of the graft was noted in the host eye, neither was any change observed in the contralateral, unoperated eye. In conclusion, neuroretinal cells were injected into the subretinal space of 14 patients with advanced RP with no clinical appearance of detrimental effects at the time of surgery or up to 40 months postinjection except in 1 patient who developed retinal detachment. This sets the stage for a phase II clinical trial to determine the possible beneficial effects of this procedure in patients blinded by degenerative retinal disease.

    The purpose of the study was to determine the long-term safety and effectiveness of high-dose immunosuppressive therapy (HDIT) followed by autologous hematopoietic cell transplantation (AHCT) in advanced multiple sclerosis (MS). TBI, CY and antithymocyte globulin were followed by transplantation of autologous, CD34-selected PBSCs. Neurological examinations, brain magnetic resonance imaging and cerebrospinal fluid (CSF) for oligoclonal bands (OCB) were serially evaluated. Patients (n=26, mean Expanded Disability Status Scale (EDSS)=7.0, 17 secondary progressive, 8 primary progressive, 1 relapsing/remitting) were followed for a median of 48 months after HDIT followed by AHCT. The 72-month probability of worsening ≥1.0 EDSS point was 0.52 (95% confidence interval, 0.30-0.75). Five patients had an EDSS at baseline of ≤6.0; four of them had not failed treatment at last study visit. OCB in CSF persisted with minor changes in the banding pattern. Four new or enhancing lesions were seen on MRI, all within 13 months of treatment. In this population with high baseline EDSS, a significant proportion of patients with advanced MS remained stable for as long as 7 years after transplant. Non-inflammatory events may have contributed to neurological worsening after treatment. HDIT/AHCT may be more effective in patients with less advanced relapsing/remitting MS.

    The assessment and management of tricuspid valve disease evolved significantly in the last decade. Tricuspid regurgitation is a frequent heart valve disease and it is most often secondary, due to annular dilatation and leaflet tethering from right ventricular remodelling. The indications for tricuspid valve surgery are several and mainly related to the underlying disease, to the severity of the regurgitation and to the right ventricular function. Moreover, surgical tricuspid repair has been avoided for years, because of the erroneous concept that tricuspid regurgitation should disappear once the primary pathology on the left heart has been resolved. Instead, during the last few years, many investigators have reported evidence in favour of a more aggressive surgical approach to functional tricuspid regurgitation, recognising the risk of progressive tricuspid insufficiency in patients with annular dilatation and only moderate regurgitation (or less) at the time of surgery. This concept, along with the acute and long-term outcomes of tricuspid surgical repair techniques and tricuspid replacement are discussed in this review.

    Cyclophilin D is a peptidyl-prolyl cis-trans isomerase localized in the mitochondrial matrix. Although its effects on mitochondrial characteristics have been well studied, its relation to the uptake of molecules by mitochondria remains unknown. Here, we demonstrated the effects of cyclophilin D on the intracellular translocation of calcein AM. Following addition of calcein AM to control cells or cells overexpressing wild-type cyclophilin D, calcein fluorescence was observed in mitochondria. However, long-term inhibition of cyclophilin D in these cells altered the localization of calcein fluorescence from mitochondria to lysosomes without changing mitochondrial esterase activity. In addition, depletion of glucose from the medium recovered calcein localization from lysosomes to mitochondria. This is the first demonstration of the effects of cyclophilin D on the intracellular translocation of molecules other than proteins and suggests that cyclophilin D may modify mitochondrial features by inducing the translocation of molecules to the mitochondria through the mechanism associated with cellular energy metabolism.

    Little is known about the familial characteristics of children with severe receptive specific language impairment (SLI). Affected children are more likely to have long-term problems than those with expressive SLI but to date they have only been described as small cohorts within SLI populations. We therefore aimed to describe the clinical and familial characteristics of severe receptive SLI as defined by a rigorous phenotype and to establish whether non-word repetition showed a relationship with language impairment in these families. Cross-sectional study of children who met ICD-10 (F80.2) criteria for receptive SLI at school entry, their siblings and genetic parents with standardised measures of language and non-verbal IQ, phonological auditory memory and speech sound inventory. At a mean of 6 years after school entry with a severe receptive SLI, the 58 participants had a normal mean and standard deviation non-verbal IQ, but only 3% (two) had attained language measures in the normal range. One third still had severe receptive language impairment. One third of siblings not known to be affected had language levels outside the normal range. Phonological auditory memory was impaired in most family members. Severe receptive SLI is nearly always associated with an equally severe reduction in expressive language skills. Language impairment in siblings may go undetected and yet they are at high risk. Family members had weak phonological auditory memory skills, suggesting that this could be a marker for language acquisition difficulties. Receptive SLI rarely resolves and trials of therapy are urgently needed.

    Climate warming is projected to affect forest water yields but the effects are expected to vary. We investigated how forest type and age affect water yield resilience to climate warming. To answer this question, we examined the variability in historical water yields at long-term experimental catchments across Canada and the United States over 5-year cool and warm periods. Using the theoretical framework of the Budyko curve, we calculated the effects of climate warming on the annual partitioning of precipitation (P) into evapotranspiration (ET) and water yield. Deviation (d) was defined as a catchment's change in actual ET divided by P [AET/P; evaporative index (EI)] coincident with a shift from a cool to a warm period – a positive d indicates an upward shift in EI and smaller than expected water yields, and a negative d indicates a downward shift in EI and larger than expected water yields. Elasticity was defined as the ratio of interannual variation in potential ET divided by P (PET/P; dryness index) to interannual variation in the EI – high elasticity indicates low d despite large range in drying index (i.e., resilient water yields), low elasticity indicates high d despite small range in drying index (i.e., nonresilient water yields). Although the data needed to fully evaluate ecosystems based on these metrics are limited, we were able to identify some characteristics of response among forest types. Alpine sites showed the greatest sensitivity to climate warming with any warming leading to increased water yields. Conifer forests included catchments with lowest elasticity and stable to larger water yields. Deciduous forests included catchments with intermediate elasticity and stable to smaller water yields. Mixed coniferous/deciduous forests included catchments with highest elasticity and stable water yields. Forest type appeared to influence the resilience of catchment water yields to climate warming, with conifer and deciduous catchments more susceptible to

    Dysphagia is a major risk factor for morbidity and mortality in critically ill patients treated in intensive care units (ICUs). Structured otorhinolaryngological data on dysphagia in ICU survivors with severe sepsis are missing. In a prospective study, 30 ICU patients with severe sepsis and thirty without sepsis as control group were examined using bedside fiberoptic endoscopic evaluation of swallowing after 14 days in the ICU (T1) and 4 months after onset of critical illness (T2). Swallowing dysfunction was assessed using the Penetration-Aspiration Scale (PAS). The Functional Oral Intake Scale was applied to evaluate the diet needed. Primary endpoint was the burden of dysphagia defined as PAS score >5. At T1, 19 of 30 severe sepsis patients showed aspiration with a PAS score >5, compared to 7 of 30 in critically ill patients without severe sepsis (p = 0.002). Severe sepsis and tracheostomy were independent risk factors for severe dysphagia with aspiration (PAS > 5) at T1 (p = 0.042 and 0.006, respectively). 4-month mortality (T2) was 57 % in severe sepsis patients compared to 20 % in patients without severe sepsis (p = 0.006). At T2, more severe sepsis survivors were tracheostomy-dependent and needed more often tube or parenteral feeding (p = 0.014 and p = 0.040, respectively). Multivariate analysis revealed tracheostomy at T1 as independent risk factor for severe dysphagia at T2 (p = 0.030). Severe sepsis appears to be a relevant risk factor for long-term dysphagia. An otorhinolaryngological evaluation of dysphagia at ICU discharge is mandatory for survivors of severe critical illness to plan specific swallowing rehabilitation programs.

  8. Understanding the fate of black (pyrogenic) carbon in soil: Preliminary results from a long term field trial

    Black carbon (BC, also known as pyrogenic carbon) is an 'inert' form of carbon and has been proposed as a means of long-term carbon sequestration, particularly by amending soils and sediments with BC known as biochar. While there is abundant anecdotal evidence of biochar stability over extended timescales it is essential to gain a greater understanding of the degree and mechanisms of biochar degradation in the environment. This study aims to quantitatively assess the stability of biochar by investigating samples from field degradation trials first buried during 2009 in a tropical soil, and recovered after 12 and 36 month intervals. Catalytic hydropyrolysis (HyPy) is a novel analytical tool for the isolation of BC [1] in which high hydrogen pressure (150 bar) and a sulphided Mo catalyst reductively remove the non-BC fraction of the chars, and so isolate the most stable portion of the biochar, defined as BC(HyPy). This method also allows for the non-BC(HyPy) fraction of a sample, which from charcoal is known to include small ring PAHs (oceans [5], implying that BC cycling could be faster than previously thought [6]. Longer term field trials will be required (analysis of the 36 month samples) to observe systematic changes in the PAH distribution of the non-BCC(HyPy) fractions isolated form aged chars, although natural analogues with a better constrained environmental history may also be useful.

    This study aims to illustrate a multiparametric automatic method for monitoring long-term reproducibility of digital mammography systems, and its application on a large scale. Twenty-five digital mammography systems employed within a regional screening programme were controlled weekly using the same type of phantom, whose images were analysed by an automatic software tool. To assess system reproducibility levels, 15 image quality indices (IQIs) were extracted and compared with the corresponding indices previously determined by a baseline procedure. The coefficients of variation (COVs) of the IQIs were used to assess the overall variability. A total of 2553 phantom images were collected from the 25 digital mammography systems from March 2013 to December 2014. Most of the systems showed excellent image quality reproducibility over the surveillance interval, with mean variability below 5%. Variability of each IQI was 5%, with the exception of one index associated with the smallest phantom objects (0.25 mm), which was below 10%. The method applied for reproducibility tests-multi-detail phantoms, cloud automatic software tool to measure multiple image quality indices and statistical process control-was proven to be effective and applicable on a large scale and to any type of digital mammography system. • Reproducibility of mammography image quality should be monitored by appropriate quality controls. • Use of automatic software tools allows image quality evaluation by multiple indices. • System reproducibility can be assessed comparing current index value with baseline data. • Overall system reproducibility of modern digital mammography systems is excellent. • The method proposed and applied is cost-effective and easily scalable.

    The purpose of the present study was to clarify whether chronically elevated plasma neuropeptide Y (NPY) might affect heart function and cardiac remodeling in rats. Male Wistar rats were administered NPY (85 μg for 30 days) by mini-osmotic pump subcutaneously implanted between the scapulae. Associated indices for heart function, cardiac remodeling and hypertrophy were evaluated. Compared to the sham group, the baseline systolic blood pressure (SBP) in rats administered NPY was significantly increased; cardiac function was significantly decreased, as indicated by reduced ejection fraction (EF), left ventricular end-systolic pressure (LVESP), maximum change velocity of left ventricular pressure in the isovolumic contraction or relaxation period (± dp/dtmax) and increased left ventricular end-diastolic pressure (LVEDP); hematoxylin-eosin (H&E) staining detection displayed enlarged cell areas and a consistent increase in heart-to-body weight ratios (HW/BW) was observed; quantitative real time PCR (qRT-PCR) and Western blot analysis showed markedly increased expressions of β-myosin heavy chain (β-MHC), calcineurin (CaN) and phosphorylated p38 proteins, while no changes were found in the expressions of p38 total protein and the phosphorylations of JNK and ERK. This study reported for the first time that long-term elevated plasma concentration of NPY could induce cardiac dysfunction and cardiac hypertrophy and this phenomenon could, in part, be mediated by the Ca2+/CaM-dependent CaN pathway and p38 mitogen-activated protein kinase (MAPK) signal pathway in rats. © 2015 S.

    OBJECTIVE: This evaluated the long-term outcome after endoscopic thoracic sympathectomy (ETS) from below D1 to D4, using a single-site access technique for primary hyperhidrosis of the upper limbs. SUMMARY BACKGROUND DATA: Primary hyperhidrosis of the upper limbs is a distressing and often socially disabling condition. Endoscopic thoracic sympathectomy is considered the treatment of choice, causing minimal morbidity and high initial success rates. However, data regarding long-term results are scarce. METHODS: Two hundred seventy of 323 patients (83.7%), in whom 480 sympathectomies were performed, answered a questionnaire after a mean of 14.6 years postoperatively regarding the early postoperative result, side effects, and complications caused by the operation and long-term results with particular emphasis on patient satisfaction. RESULTS: There was no postoperative mortality and no major complications requiring surgical reintervention. A majority of the patients (98.1%) were relieved, and 95.5% were satisfied initially. Permanent side effects included compensatory sweating in 67.4%, gustatory sweating in 50.7% and Horner's trias in 2.5%. However, patient satisfaction declined over time, although only 1.5% recurred. This left only 66.7% satisfied, and a 26.7% partially satisfied. Compensatory and gustatory sweating were the most frequently stated reasons for dissatisfaction. Individuals operated for axillary hyperhidrosis without palmar involvement were significantly less satisfied (33.3% and 46.2%, respectively). PMID:8024363

    Coiling associated with placement of self-expandable intracranial stents has amplified the treatment of intracranial wide-necked aneurysms, but the durability of this treatment and the existence of delayed recurrence are not yet well known. The purpose of this report is to present our experience with the Neuroform Stent associated with coiling and to evaluate complications, effectiveness, and long-term results of this technique. A retrospective study of 42 patients with wide-necked cerebral aneurysms treated with the Neuroform Stent was performed. Mean aneurysm size was 11.3 mm. Mean neck size was 5.33 mm. All patients were treated with coiling and stenting. Clinical and angiographic follow-up was available in 38 patients (90.5%). The overall follow-up time ranged from 6 months to 5 years (mean, 42 months), but most of the patients (92%) had a follow-up period superior to 1 year. Successful deployment of 41 stents (97%) was obtained. Permanent procedural morbidity was observed in only one patient (2.4%). Long-term complete aneurysmal occlusion was obtained in 27 patients (71%). Aneurysmal regrowth was observed in four patients (9.5%) on the first control angiogram. After the first control angiogram, no delayed recanalization or regrowth was observed. During the follow-up period, there were no hemorrhagic events, no delayed thrombosis, and no stent displacement. Our results demonstrate the effectiveness of the technique, a small rate of procedural complications, and long-term tolerance of the Neuroform Stent. Despite some evidence of early aneurysmal recurrence, long-term durability of stent-assisted aneurysm occlusion is stable after the first year. (orig.)

    Full Text Available Purpose: We conducted a meta-analysis to evaluate and compare the short- and long-term results of laparoscopic colorectal surgery (LCRS and conventional open surgery (OCRS for colorectal cancer (CRC.Methods: We searched relevant papers published between January 1990 and May 2011. We analyzed the outcomes of each type of surgery over the short- and long-term periods.Results: In the short-term period, we found no significant differences in overall perioperative complications and anastomotic leakage between LCRS and OCRS groups. We found no significant differences in overall, distant, local and wound-site recurrence, overall mortality, 3 and 5 year disease-free survival rate, and cancer-related mortality between the 2 groups.Conclusions: LCRS has the benefits of reducing intraoperative blood loss, earlier resumption of oral intake, and shorter duration of hospital stay in the short-term. The long-term outcomes of LCRS seem to be similar to those of OCRS.

    Neuroblastoma (NB) is the most frequent indication for extracranial pediatric radiotherapy. As long-term survival of high-risk localized NB has greatly improved, we reviewed treatment-related late toxicities in pediatric patients who received postoperative radiotherapy (RT) for localized NB within two French prospective clinical trials: NB90 and NB94. From 1990-2000, 610 children were enrolled. Among these, 35 were treated with induction chemotherapy, surgery, and RT. The recommended RT dose was 24 Gy at ≤ 2 years, 34 Gy at > 2 years, ± a 5 Gy boost in both age groups. The 22 patients still alive after 5 years were analyzed. The median follow-up time was 14 years (range 5-21 years). Late effects after therapy occurred in 73 % of patients (16/22), within the RT field for 50 % (11/22). The most frequent in-field effects were musculoskeletal abnormalities (n = 7) that occurred only with doses > 31 Gy/1.5 Gy fraction (p = 0.037). Other effects were endocrine in 3 patients and second malignancies in 2 patients. Four patients presented with multiple in-field late effects only with doses > 31 Gy. After a median follow-up of 14 years, late effects with multimodality treatment were frequent. The most frequent effects were musculoskeletal abnormalities and the threshold for their occurrence was 31 Gy. (orig.)

    Purpose: To evaluate CT-guided radiofrequency (RF) ablation of osteoid osteoma using internally cooled monopolar RF electrodes for technical success, complications and clinical long-term success. Materials and Methods: Between April 1999 and July 2009, 23 patients were treated under general anesthesia with CT-guided RF ablation using an internally cooled monopolar single RF electrode (Cool-tip, Valleylab, TycoHealthcare, Boulder, USA; active tip: 10 mm). For the removal of the nidus, we used either a manual or an automated drill. The technical success was evaluated by a CT scan (MSCT, Siemens Medical Solutions, Forchheim). The clinical long-term success was investigated by questioning patients prior to discharge, and after 6, 12 and 18 months. After 18 months, patients were interviewed on an annual basis. Results: The technical success rate was 100 %. The nidus was located in n = 19 cases at the lower extremity and in n = 4 cases at the upper extremity. Minor complications were observed for n = 2 patients. The mean hospitalization time was 1.5 d (1-2 d). The mean follow-up was 75.9 months (18-120 months) for n = 23 patients. No local recurrence was observed. One patient had intermediate pain one week after RF ablation without recurrent symptoms. Conclusion: CT-guided RF ablation using an internally cooled monopolar single RF electrode is an effective and safe minimally invasive method for the treatment of osteoid osteoma with excellent clinical long-term success.

    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.

    Objective: To summarize results of endovascular treatment for auto-immune disease related abdominal aorta pseudo-aneurysm(AIPA), and to analysis clinical predictors of long term major adverse clinical events(MACE). Methods: Retrospectively collected endovascular treatment for AIPA cases in Peking Union Medical College Hospital within 2000 to 2015. Twenty-nine cases with AIPA treated by endovascular therapy were enrolled in this study. Twenty five cases were male, range from 23 to 67 years old, mean age was (39.3±11.4) years old.Demographic characters, locations of aneurysms, type to auto-immune disease, immuno medical therapy, operation strategy and long term follow-up data were reported. Statistical analysis was made to verify clinical predictors of long-term MACE. Results: Among the 29 cases, 22 cases with bechet's disease, 4 cases with Takayasu's arteritis, 2 cases with systemic lupus erythematosus, 1 cases with polyarteritis nodosa. Eight cases had ruptured or pending ruptured pesudo-aneurysms, the rest 21 cases had dull pain or no overt symptome. Twenty-four cases had infra-renal artery aneurysms, two were para-and supra-renal artery, two were supra-celiac artery, and the rest one had multiple aneurysms involved thoracic and abdominal aorta.All the cases received regular immune medical therapy except the three emergency cases. All the operations were under general anaesthesia. Nineteen cases underwent classical Endovascular aortic aneurysm repair (EVAR), 5 cases underwent fenestration EVAR, the rest 5 cases underwent hybrid procedure. All the 29 operations were successful, without conversion to open surgery. Major peri-operation complication included 3 incision infection, 3 pulmonary infection. No death occurred. All the cases received regular follow-up from 1 to 120 months. There were five recurrence of pseudo-aneurysm, 1 case suffered from iliac limb occlusion. 5 cases received re-intervention procedure. No occlusion of revascularizal visceral artery was

    The impact of selenium (Se) in carcinogenesis is still debatable due to inconsistent results of observational studies, recent suspicion of diabetic side effects and e.g. dual roles of glutathione peroxidases (GPx). Previously, our group introduced long-term studies on lung carcinogenesis using the jaagtsiekte sheep retrovirus (JSRV) induced ovine pulmonary adenocarcinoma (OPA) as an innovative animal model. The present report describes the results of sufficient (0.2 mg Se/kg dry weight (dw)) vs. marginal (CT) evaluation of lung cancer progression, final pathological examination, evidence of pro-viral JSRV-DNA in lung, lymph nodes and broncho-alveolar lavage cells as well as biochemical analysis of Se, GPx1 and thioredoxin reductase (TrxR) activity in lung tissue were recorded. Additionally, immunohistochemical determination of GPx1 expression in unaffected and neoplastic lung cells was implemented. The feeding regime caused significant differences in Se concentration and GPx1 activity in lung tissue between groups, whereas TrxR activity remained unaffected. JSRV was evident in broncho-alveolar lavage cells, lung tissue and lung lymph nodes. Quarterly executed CT could not demonstrate differences in lung cancer proliferation intensity. Necropsy and histopathology substantiated CT findings. Immunohistochemical analysis of GPx1 in lung tissue suggested a coherency of GPx1 immunolabelling intensity in dependence of tumour size. It was concluded that the model proved to be suitable for long-term studies of lung cancer proliferation including the impact of modifiable nutritional factors. Proliferation of OPA was unaffected by marginal vs. sufficient nutritional Se supply.

    We present the preliminary results of a retrospective study on 56 patients who underwent the Kapandji-Sauvé procedure for chronic disorders of the distal radioulnar joint (DRUJ). Outcome was assessed with special regard to the long-term results. The average follow-up was 5.9 years (1 to 12 years). 15 of the 56 operations were performed before 1996. Most procedures were performed because of secondary arthrosis or chronic dislocation of the DRUJ after distal radius fracture. Patients were assessed for pain, range of motion of wrist and forearm and radiological features. The DASH score and Mayo wrist score were used. Pain was improved in 94 % of the patients, but only 53 % were free of symptoms during heavy manual labour concerning the operated site. In four cases symptoms of ulnar impingement were found. Improvement in range of motion of wrist and forearm was significant. The post-operative DASH score was 22.6 +/- 20.0 and the Mayo wrist score was 79.5 +/- 14.6. One non-union of the DRUJ with consecutive fracture of the fixation screw and an algodystrophy in another case were found as postoperative complications. The only long-term complication consisted of a beginning humeroradial arthrosis ten years after the operation. The results demonstrate high patient satisfaction and reliable improvement in range of motion. Our results confirm the Kapandji-Sauvé procedure to be a reliable salvage procedure for arthrosis or chronic dislocation of the DRUJ even after long-term follow up.

    Thirty surviving patients after corrective surgery for tetralogy of Fallot with right ventricular outflow tract reconstruction (RVOTR) using monocusp ventricular outflow patch (MVOP) were reviewed retrospectively to determine the long-term results. The age at operation ranged from 2 to 55 years with a mean of 19 years, and follow-up extended to 18.2 years (cumulative: 345.4 patient-year). There were 4 late deaths (1.2% per patient-year), and the cumulative survival rate was 85.3% at 18 years after the corrective surgery. Eight patients (2.3% per patient-year) required intracardiac reoperations mostly resulted from problems after RVOTR with MVOP, such as recurrent stenosis of right ventricular outflow tract (3 cases) or pulmonary valvular incompetence (4 cases). In addition, one patient underwent balloon angioplasty for the recurrent stenosis located in the distal end of MVOP. Freedom from surgical or catheter reintervention for the MVOP-related complication was 60.6% at 18 years after the corrective surgery. MVOP caused compression of the pulmonary artery at the distal end of the anastomosis and reoperation in a younger patients quite early after the corrective surgery. Like other transannular patches, tissue failure and degeneration of MVOP were inevitable, and resulted in severe pulmonary valvular incompetence that required the valve replacement in 4 patients (1.3% per patient-year). Freedom from pulmonary valve replacement was 71.2% at 18 years after the corrective surgery. As long-term results, our experiences emphasize the need for an innovative transannular patch that possesses significantly better long-term durability.

  5. Microstructure and diffraction pattern changes resulted from long-term aging of martensite CuZnAlMnNi shape memory alloy

    Institute of Scientific and Technical Information of China (English)

    2002-01-01

    Microstructures of a CuZnAlMnNi shape memory alloy in the as-quenched and long-term aged conditions were investigated by transmission electron microscopy. Aged for one year in martensite phase, an equilibrium (-phase with fcc structure was observed in the M18R martensite matrix, accompanied by the appearance of a novel diffraction pattern. By analysis, it was suggested that the novel pattern results from the (-phase and the martensite matrix remaining in seven fine plates which produce intense secondary diffraction effect when the diffraction beams enter from one phase into another.

    The RPC chambers in the L3 forward-backward muon spectrometer have been operational from 1994 to the end of LEP running. After dismantling of the L3 detector some of the RPCs modules have been transported to Napoli where their performance has been re-measured with cosmic rays. Results of long-term performance in the LEP environment and of laboratory tests with cosmic rays will be presented. One of the 20 tested chambers, the one with the worst performances, was opened. The chamber was inspected with microscope and also a chemical analysis of the oil coating was performed. We will report in detail about this analysis.

    Objectives: To compare the long-term outcome after uterine artery embolization (UAE) versus magnetic resonance-guided high-intensity focused ultrasound (MR-g HIFU) for symptomatic uterine fibroids. Methods: Seventy-seven women (median age, 39.3 years; range, 29.2–52.2 years) with symptomatic uterine fibroids, equally eligible for UAE and MR-g HIFU based on our exclusion criteria underwent treatment (UAE, N = 41; MR-g HIFU, N = 36) from 2002 to 2009 at our institution. Symptom severity (SS) and total health-related quality of life (Total HRQoL) scores were assessed by the uterine fibroid symptom and quality of life (UFS-QoL) questionnaire before treatment and at long-term follow-up after UAE (median 61.9 months) and after MR-g HIFU (median: 60.7 months). Re-intervention rates were assessed for each therapy and compared. Results: Re-intervention was significantly lower after UAE (12.2%) than after MR-g HIFU (66.7%) at long-term follow-up (p < 0.001). After UAE changes in SS (50 pre-treatment vs. 6.3 post-treatment) and Total HRQoL (57.8 pre-treatment vs. 100 post-treatment) were significantly better than changes in SS (42.2 pre-treatment vs. 26.6 post-treatment) and Total HRQoL score (66.4 pre-treatment vs. 87.9 post-treatment) after MR-g HIFU (p = 0.019 and 0.049 respectively). Conclusions: Improvement of SS and Total HRQoL scores was significantly better after UAE resulting in a significant lower re-intervention rate compared to MR-g HIFU.

    We report our experience with eleven patients treated for disabling genu valgum from 1979 to 1994. Genu valgum resulted from femoral deformation in all patients. Ten had a congenital condition and one a post-traumatic knee. IKS scores were used for the clinical evaluation. The lateral femorotibial joint space and the lateral femoral angle (LFA) were measured on plain films. Goniometry was used to measure the axis of the loaded lower limb. All patients underwent osteotomy of the distal femur for varisation and plate fixation. One patient required revision for a unicompartment lateral prosthesis subsequent to fracture of the homolateral lateral tibial plateau. Mean follow-up was 10.5 years (3.5-21.5). There were no cases of nonunion. Four patients had a good or excellent knee score. Eight patients had a good or excellent function score. Osteoarthritis worsened in two patients. The mean LFA increased from 72.5 degrees preoperatively to 83.5 degrees postoperatively and a last follow-up. Mean genu valgum was 13 degrees preoperatively and 2 degrees at last follow-up. All patients except one were satisfied or very satisfied. Insufficient correction appeared to be the main complaint. These results and results reported in the literature demonstrate that distal femoral osteotomy for disabling genu valgum is an effective treatment if the correction is complete and osteosynthesis effective, providing long lasting results when femoral deformation is involved and osteoarthritis limited.

    The objective was to determine the risk of post-operative complications in patients receiving high-dose pelvic irradiation before radical cystectomy and urinary diversion. The post-operative course, including the duration of hospital stay, peri-operative complications and early functional results, did not differ from a control group of non-irradiated patients, and no patients died. The mean follow-up was 22 months (range 10-37) and revealed satisfactory results in seven of 11 patients. A neovesicoperitoneal fistula developed in one woman 10 months after surgery and was repaired by laparotomy. A neovesicovaginal fistula led to supravesical urinary diversion in the second woman. High-dose pelvic irradiation should not be a primary contra-indication for orthotopic urinary diversion using segments of small intestine. For patients who undergo combined external and after loading radiotherapy, the indication for orthotopic bladder replacement should be considered critically. (Author).

    We compared the impact of low and high-pressure balloon inflation on acute and late angiographic results of Multilink stent. Low-pressure balloon inflation (9.5 +/- 1.9 atm) was used in 43 stents and high pressure (17.1 +/- 1.5 atm) in 44. A larger immediate luminal gain was achieved in stents with high-pressure balloon inflation (1.80 +/- 0.26 vs. 1.47 +/- 0.62; P = 0.002), resulting in a larger mean diameter in this group (2.71 +/- 0.37 vs. 2.48 +/- 0.47; P = 0.017). At follow-up, a larger luminal diameter was achieved in the high pressure group (1.93 +/- 0.72 vs. 1.45 +/- 0.66; P = 0.002) and a trend to a lower rate of angiographic restenosis (15% vs. 38%, P = 0.08).

    Most of the published empirical data on indoor air concentrations resulting from vapor intrusion of contaminants from underlying groundwater are for residential structures. The National Aeronautics and Space Administration (NASA) Research Park site, located in Moffett Field, CA, and comprised of 213 acres, is being planned for redevelopment as a collaborative research and educational campus with associated facilities. Groundwater contaminated with hydrocarbon and halogenated hydrocarbon volatile organic compounds (VOCs) is the primary environmental medium of concern at the site. Over a 15-month period, approximately 1000 indoor, outdoor ambient, and outdoor ambient background samples were collected from four buildings designated as historical landmarks using Summa canisters and analyzed by the U.S. Environmental Protection Agency TO-15 selective ion mode. Both 24-hr and sequential 8-hr samples were collected. Comparison of daily sampling results relative to daily background results indicates that the measured trichloroethylene (TCE) concentrations were primarily due to the subsurface vapor intrusion pathway, although there is likely some contribution due to infiltration of TCE from the outdoor ambient background concentrations. Analysis of the cis-1,2-dichloroethylene concentrations relative to TCE concentrations with respect to indoor air concentrations and the background air support this hypothesis; however, this indicates that relative contributions of the vapor intrusion and infiltration pathways vary with each building. Indoor TCE concentrations were also compared with indoor benzene and background benzene concentrations. These data indicate significant correlation between background benzene concentrations and the concentration of benzene in the indoor air, indicating benzene was present in the indoor air primarily through infiltration of outdoor air into the indoor space. By comparison, measured TCE indoor air concentrations showed a significantly different

    clinical, morphological findings correlated (p=0,041) as well as there was a connection to the static range of motion (p=0,001). Though, there was no significant correlation between the score and the dynamic range of motion, which represents the results of the gaitlab analysis. However the dynamic range of motion correlated to the R/L ratio significantly(p<0,0001). Finally the result of the enforced treatment of clubfoot was able to be assessed good as far as the subjective condition of patients is concerned, in spite of the poor morphological and radiological result after 20 years. Moreover it was proved by gaitlab analysis, that dynamic ankle mobility is influenced by talar flattening. In this retrospective study 19 patients with altogether 27 congenital clubfeet were evaluated. Five patients (26 %) were female and 14 patients (74 %) were male. Between the operation and the examination there was an average follow up time of 21,5 years. In 8 cases the method of Turco had been used and 19 feet had been tre...

    This study explored the efficacy of visual input enhancement, specifically essay enhancement, for facilitating deaf college students' improvement in English grammatical knowledge. Results documented students' significant improvement immediately after a 10-week instructional intervention, a replication of recent research. Additionally, the results of delayed assessment documented students' significant retention of that improvement five and a half months beyond the instructional intervention period. Essay enhancement served to highlight, via a coding procedure, students' successful and unsuccessful production of discourse-required target grammatical structures. The procedure converted students' written communicative output into enhanced input for inducing noticing of grammatical form and, through essay revision, establishing form-meaning connections leading to acquisition. With its optimal design characteristics supported by theoretical and empirical research, essay enhancement is a highly effective methodology that can be easily implemented as primary or supplementary English instruction for deaf students. The results of this study hold great promise for facilitating deaf students' English language and literacy development and have broad implications for second-language research, teaching, and learning.

    Full Text Available Abstract Background Engaging end-users of research in the process of disseminating findings may increase the relevance of findings and their impact for users. We report findings from a case study that explored how involvement with the Translating Research in Elder Care (TREC study influenced management and staff at one of 36 TREC facilities. We conducted the study at ‘Restwood’ (pseudonym nursing home because the Director of Care engaged actively in the study and TREC data showed that this site differed on some areas from other nursing homes in the province. The aims of the case study were two-fold: to gain a better understanding of how frontline staff engage with the research process, and to gain a better understanding of how to share more detailed research results with management. Methods We developed an Expanded Feedback Report for use during this study. In it, we presented survey results that compared Restwood to the best performing site on all variables and participating sites in the province. Data were collected regarding the Expanded Feedback Report through interviews with management. Data from staff were collected through interviews and observation. We used content analysis to derive themes to describe key aspects related to the study aims. Results We observed the importance of understanding organizational routines and the impact of key events in the facility’s environment. We gleaned additional information that validated findings from prior feedback mechanisms within TREC. Another predominant theme was the sense that the opportunity to engage in a research process was reaffirming for staff (particularly healthcare aides—what they did and said mattered, and TREC provided a means of having one’s voice heard. We gained valuable insight from the Director of Care about how to structure and format more detailed findings to assist with interpretation and use of results. Conclusions Four themes emerged regarding staff engagement with

    Highlights: • Study reports RC frequency in lymphocytes in the group of 3242 subjects. • The highest RC frequency was present in children environmentally exposed to radon. • In 85% of RCs double minutes were observed. • Results suggests that radon may be the leading factors causing RC. • RC may be a candidate biomarker for exposure to α-emitters. - Abstract: Cells with specific multiple chromosome aberrations, defined as rogue cells (RC) have been described in different populations, predominantly those exposed to radiation. The frequency, etiology and related health risks have still not been elucidated due to their low frequency of occurrences and rarely performed studies. This study reports RC frequency using chromosome aberration (CA) assay in peripheral lymphocytes in the group of 3242 subjects, during a 30-year long follow-up study in a general rural and urban population, children environmentally exposed to radon, occupationally exposed population and lung cancer patients from the Kemerovo region (Siberia, Russian Federation). Results show that the highest RC frequency was present in children environmentally exposed to radon and the lowest in the general urban population. Total frequency of CA did not correlate with frequency of RC. Genotoxic analysis of air and water samples excluded anthropogenic pollution as a possible cause of genome damage and RC frequency. In 85% of RCs, double minutes, observed in a large number of human tumors, were present. Results of CA analysis suggested that radon and its decay products (alpha-emitters) were the leading factors causing RC in subjects exposed to high LET radiation. Thus, RC may be a candidate biomarker for exposure to this type of radiation.

    Purpose: To observe, by retrospective analysis, the curative effects and complications due to californium-252 ({sup 252}Cf) neutron intracavitary brachytherapy (ICBT) combined with external-beam radiotherapy (EBRT) in the treatment of cervical cancer. Methods and Materials: From February 1999 to December 2007, 696 patients with cervical cancer (Stages IB to IIIB) were treated with {sup 252}Cf-ICBT in combination of EBRT. Of all, 31 patients were at Stage IB, 104 at IIA, 363 at IIB, 64 at IIIA, and 134 at IIIB. Californium-252 ICBT was delivered at 7-12 Gy per insertion per week, with a total dose of 29-45 Gy to reference point A in three to five insertions. The whole pelvic cavity was treated with 8-MV X-ray external irradiation at 2 Gy per fraction, four times per week. After 16-38 Gy of external irradiation, the center of the whole pelvic field was blocked with a 4-cm-wide lead shield, with a total external irradiation dose of 44-56 Gy. The total treatment course was 5 to 6 weeks. Results: Overall survival rate at 3 and 5 years for all patients was 76.0% and 64.9%, respectively. Disease-free 3- and 5-year survival rates of patients were 71.2% and 58.4%, respectively. Late complications included vaginal contracture and adhesion, radiation proctitis, radiation cystitis, and inflammatory bowel, which accounted for 5.8%, 7.1%, 6.2%, and 4.9%, respectively. Univariate analysis results showed significant correlation of stage, age, histopathologic grade, and lymph node status with overall survival. Cox multiple regression analysis showed that the independent variables were stage, histopathologic grade, tumor size, and lymphatic metastasis in all patients. Conclusion: Results of this series suggest that the combined use of {sup 252}Cf-ICBT with EBRT is an effective method for treatment of cervical cancer.

    In the course of the Joint Danube Survey 3 (JDS3), coordinated by the International Commission for the Protection of the Danube River (ICPDR), laboratory ships travelled 2375km down the Danube River engaging in sampling, processing and on-board analyses during the summer of 2013. The results of the radiometric analysis of (90)Sr, (137)Cs and natural radionuclides in recent riverbed sediment are presented. The activity concentrations of (90)Sr and (137)Cs in Danube sediments have been found below 100Bq/kg.

    Quality of outcome of the Heller-Dor operation is sometimes different between studies, likely because of technical reasons. We analyze the details of myotomy and fundoplication in relation to the results achieved over a 30-year single center's experience. From 1979-2008, a long esophagogastric myotomy and a partial anterior fundoplication to protect the surface of the myotomy was routinely performed with intraoperative manometry in 202 patients (97 men; median age, 55.5 years; interquartile range, 43.7-71 years) through a laparotomy and in 60 patients (24 men; median age, 46 years; interquartile range, 36.2-63 years) through a laparoscopy. The follow-up consisted of periodical interview, endoscopy, and barium swallow, and a semiquantitative scale was used to grade results. Mortality was 1 of 202 in the laparotomy group and 0 of 60 in the laparoscopy group. Median follow-up was 96 months (interquartile range, 48-190.5 months) in the laparotomy group and 48 months (interquartile range, 27-69.5 months) in the laparoscopy group. At intraoperative manometry, complete abolition of the high-pressure zone was obtained in 100%. The Dor-related high-pressure zone length and mean pressure were 4.5 ± 0.4 cm and 13.3 ± 2.2 mm Hg in the laparotomy group and 4.5 ± 0.5 cm and 13.2 ± 2.2 mm Hg in the laparoscopy group (P = .75). In the laparotomy group poor results (19/201 [9.5%]) were secondary to esophagitis in 15 (7.5%) of 201 patients (in 2 patients after 184 and 252 months, respectively) and to recurrent dysphagia in 4 (2%) of 201 patients, all with end-stage sigmoid achalasia. In the laparoscopy group 2 (3.3%) of 60 had esophagitis. A long esophagogastric myotomy protected by means of Dor fundoplication cures or substantially reduces dysphagia in the great majority of patients affected by esophageal achalasia and effectively controls postoperative esophagitis. Intraoperative manometry is likely the key factor for achieving the reported results. Copyright © 2010 The

    Despite good short-term results and patient satisfaction with endoscopic thoracic sympathectomy (ETS), there has been much debate on the level of sympathectomy for treatment of palmar hyperhidrosis (PH) in terms of long-term clinical outcomes. The aim of the study was to analyze the long-term recurrence and compensatory hyperhidrosis (CH) rates of ETS, comparing single-level T2 against multi-level T2-T3 ablation in single patients. Patients who had undergone treatment for PH with unilateral T2 and contralateral T2-T3 ablation in ETS were retrospectively reviewed. They were subjected to telephone interview using standardized set of interview script and questionnaire with a scoring system similar to hyperhidrosis disease severity scale. All patients were evaluated for comparison of symptom resolution, site and severity of CH, and satisfaction rates. To compare between T2 and T2-T3, the level of sympathectomy on one side is matched to the ipsilateral recurrence of PH and CH occurrence. Twenty-two patients with a mean age of 36.5 years could be reached. The mean follow-up was 8 years (range 38-153 months). The global recurrence rate for PH is 18%. CH was observed in 20 (91%) patients, and trunk compensation was the most common (18/22-82%), followed by lower limb (14/22-64%) and axilla (10/22-45%). Overall, 72.8% (16) of the patients were satisfied with the operation. Among the six patients who were not satisfied, two patients reported recurrence of symptoms, while four patients experienced some form of compensation. There was no absolute difference in the severity of sweating bilaterally for patients who reported recurrence of PH. The site and severity of CH were also bilaterally symmetrical for all patients. There was no difference in recurrence rates and CH between single-level (T2) and multi-level (T2-T3) ETSs in the long term.

  1. Combating the Urban Heat Island Effect: Results from a Long-Term Monitoring Study on Urban Green, White, and Black Roofs in New York City

    Urban heat island mitigation strategies include increasing urban vegetation and increasing the albedo of impervious surfaces. Vegetated "green" roofs can provide benefits to stormwater management, water quality, energy cost efficiency, and biodiversity in cities, but the body of research on green roofs in the US is not large and cities in the US have been slow to adopt green roofs. On the other hand, "high-albedo" white roofs have been applied more widely through projects such as New York City Cool Roofs. There are several major issues (e.g., albedo decline, product differences, and long-term temperature controls) about green and white roof performance versus typical black roofs with respect to urban heat island mitigation that have yet to be fully addressed. Here, we present data from an on-going, long-term study in New York City in which pilot, urban albedo enhancement and vegetation effects have been monitored at the building-scale since 2007. Although the urban heat island effect can be detected throughout the year, our objective for this paper was to compare green roof vegetation with those of the high-albedo roofs for their ability to reduce the electricity demand for cooling in the summer. Using energy balance methodology across our sites (three), we found that green and white roof membrane temperature peaks are on average 60°F (33°C) and 30° F (17°C), respectively, cooler than black roof temperature peaks, and that these alternative surfaces significantly reduce thermal stress to roof membranes. Interestingly, we found that industrial white membranes [thermoplastic polyolefin (TPO) and ethylene propylene diene monomer (EPDM)] stay cleaner longer, thereby, maintaining the high-albedo benefits longer than the painted roofs, which tend to lose their albedo properties rapidly. Results thus far suggest that more long-term research comparing the albedo and cooling benefits of green and white roofs to black roofs is necessary to understand temporal changes to

    Background. In this article the results are presented of a four part study on the effect of screening for scoliosis and (repeated well-care visits and freely accessible consultation hours at secondary schools, on the incidence and prevalence of (parasuicide, mental health, adolescent health compromising behaviour and lastly obesity.

    Methods. An ecologic case-referent study design was used with data from the Netherlands Bureau of Statistics, the Ministry of Defence, the 1992 High-School Student Study, all of the youth health care departments in The Netherlands and relevant censuses.

    Results. Attention to mental and physical health and health compromising behaviour, either during screening, open consultation hours or during well-care visits seems to be ineffective and in some instances even detrimental to youth health.

    Of the 18 different outcome measurements, 5 were significantly negative and none were significantly positive.

    Conclusions. This four part study does not support the hypothesis that on a population level, the preventive activities of youth health care departments such as screening for scoliosis, (more frequent well-care visits or offering open consultation hours at secondary schools, have a beneficial effect on prevention of (parasuicide, poor mental health, health compromising behaviour or obesity.

    A previous phase II clinical trial of adipose-derived stem cell (ASC) therapy for fistulae associated with Crohn's disease, a devastating condition with a high recurrence rate, demonstrated safety and therapeutic potential with a 1-year sustained response. In the present study, 41 of the 43 phase II trial patients were followed for an additional year, regardless of response in the initial year. At 24 months, complete healing was observed in 21 of 26 patients (80.8%) in modified per protocol analysis and 27 of 36 patients (75.0%) in modified intention-to-treat analysis. No adverse events related to ASC administration were observed. Furthermore, complete closure after initial treatment was well-sustained. These results strongly suggest that autologous ASCs may be a novel treatment option for Crohn's fistulae. ©AlphaMed Press.

    John R Stewart

    Full Text Available The early MIS 3 (55-40 Kyr BP associated with Middle Palaeolithic archaeology bird remains from Pin Hole, Creswell Crags, Derbyshire, England are analysed in the context of the new dating of the site's stratigraphy. The analysis is restricted to the material from the early MIS 3 level of the cave because the upper fauna is now known to include Holocene material as well as that from the Late Glacial. The results of the analysis confirm the presence of the taxa, possibly unexpected for a Late Pleistocene glacial deposit including records such as Alpine swift, demoiselle crane and long-legged buzzard with southern and/or eastern distributions today. These taxa are accompanied by more expected ones such as willow ptarmigan /red grouse and rock ptarmigan living today in northern and montane areas. Finally, there are temperate taxa normally requiring trees for nesting such as wood pigeon and grey heron. Therefore, the result of the analysis is that the avifauna of early MIS 3 in England included taxa whose ranges today do not overlap making it a non-analogue community similar to the many steppe-tundra mammalian faunas of the time. The inclusion of more temperate and woodland taxa is discussed in the light that parts of northern Europe may have acted as cryptic northern refugia for some such taxa during the last glacial. These records showing former ranges of taxa are considered in the light of modern phylogeographic studies as these often assume former ranges without considering the fossil record of those taxa. In addition to the anomalous combination of taxa during MIS 3 living in Derbyshire, the individuals of a number of the taxa are different in size and shape to members of the species today probably due to the high carrying capacity of the steppe-tundra.

    Mechanical aortic valve replacement (AVR) results have been published extensively in industrialized countries. To assess our immediate and late results in patients subjected to AVR. We retrospectively studied 194 patients subjected to isolated AVR between 1995 and 2003. Mean age was 57 +/- 13 years and 119 (61%) were male. One hundred thirty nine (73%) were in functional class III-IV, 20 (10%) had a previous cardiac operation and 25 (13%) were operated as an emergency. Surgical indication was stenosis in 110 (58%), regurgitation in 49 (26%) and stenosis/regurgitation in 31 (16%). Etiology was bicuspid valve 56 (29%), degenerative lesions 55 (28%), rheumatic valve disease 38 (20%) and endocarditis 27 (14%). Medtronic Hall was the most common prosthesis used in 157 patients (81%). Mean cardiopulmonary bypass time 97 +/- 29 min and mean cross clamp time was 69 +/- 21 min. Operative mortality was 4.6% (3% in elective surgery, 16% in emergency surgery and 0% in reoperations). Follow-up was complete in 100% of cases, totalizing 636 patients-year. Survival was 91 +/- 2%, 80 +/- 4% and 73 +/- 6%, at 1, 5 and 7 years, respectively. Multivariate risk analysis identified renal failure and endocarditis as predictors of early and late mortality. During follow up, the linear incidence rate for hemorrhage was 3.29% /patients-year, thromboembolism 2.04% patients-year and endocarditis 1.1% patients-year. AVR has low overall and elective mortality. Midterm survival is good but linear event rates related to anticoagulant treatment are higher than those previously published in industrialized countries. Renal failure and endocarditis were risk factors for early and late death.

    We investigated persistences and changes of career preferences of medical residents in Germany after two years of postgraduate training with regard to future working place and position. The results are compared with those forwarded at graduation from medical school in a gender comparative perspective. The study is based on a standardized postal survey among the participants in the "KarMed" study, originally based on 1012 graduates of the medical faculties of Erlangen, Giessen, Hamburg, Heidelberg, Cologne, Leipzig and Magdeburg in 2009. 2107 persons were contacted. The return rate at baseline was 48 %, and the two surveys after the baseline reached return rates of 87 % and 89 % respectively. In all samples 2/3 were women as in actual medical undergraduate education. Descriptive statistics and regression analysis were performed. After 2 years of residency, residents after 2 years of postgraduate training still preferred the hospital over private practice as their final workplace after postgraduate training. The attractiveness of leading positions in the hospital declined among men, whereas it was already low for women at graduation. A large proportion of those physicians preferring the ambulatory sector, especially women, wishes to work as employee instead of private practice. At the personal level, almost 60 % forwarded the same preferences as those at graduation. Gender, parenthood and region of study (East vs. West Germany) did not influence stability or change of preferences. The results demonstrate the persistence of professional preferences regarding future sector and position of medical work during postgraduate training. These preferences do neither match with principles of gender equality nor with future workforce needs (e. g. in primary care). © Georg Thieme Verlag KG Stuttgart · New York.

    Short-term radiotherapy (STR) for rectal cancer (RC) has rarely been used in Spain. The aim of the present study is to describe oncological results after RTC and surgery for RC. This is a retrospective analysis of a consecutive series of patients treated with STR and surgery for RC (1999-2012). Epidemiological data, staging, complications of STR, STR-surgery interval, surgical approach, rate of anastomotic/perineal wound dehiscence, and pathological data (regression degree and staging) were collected. Global survival, disease free survival, local recurrence rate and incidence of toxicity, response and complications of combined treatment are reported. Of 1229 patients treated, 209 patients received STR and surgery. The median follow-up was 6.2 years. Mean age was 68 years and 66% of the patients were men. A total of 88% were cT3-4 and 44% cN+17 (8.1%) patients had resectable synchronous metastases. Acute and chronic toxicity due to STR was 4 weeks. Seven patients (3.3%) presented complete response. Nine (4.3%) patients presented an local recurrence rate. Global survival at 5, 10 and 15 years was 67.8, 49.2 and 37.5%, respectively. Disease free survival at 5, 10 and 15 years was 66.1, 47.1 and 33%, respectively. The results compare favorably with multicentric historical series. STR offers certain advantages that could be increased by increasing the STR-surgery interval and/or interspersed with sequential chemotherapy. Copyright © 2017 AEC.

    The paper presents selected results of a prospective multicenter study. The reported study was aimed at the evaluation of a software-based stimulation method of computer training applied in addition to occlusion as a complementary treatment for therapy-resistant cases of amblyopia. The stimulus was a drifting sinusoidal grating of a spatial frequency of 0.3 cyc/deg and a temporal frequency of 1 cyc/sec, reciprocally coordinated with each other to a drift of 0.33 deg/sec. This pattern was implemented as a background stimulus into simple computer games to bind attention by sensory-motor coordination tasks. According to an earlier proposed hypothesis, the stimulation aims at the provocation of stimulus-induced phase-coupling in order to contribute to the refreshment of synchronization and coordination processes in the visual transmission channels. To assess the outcome of the therapy, we studied the development of the visual acuity during a period of 6 months. Our cooperating partners of this prospective multicenter study were strabologic departments in ophthalmic clinics and private practices as well. For the issue of therapy control, a partial sample of 55 patients from an overall sample of 198 patients was selected, according to the criterion of strong therapy resistance. The visual acuity was increased about two logarithmic steps by an occlusion combined with computer training in addition to the earlier obtained gain of the same amount by occlusion alone. Recalculated relatively to the duration of the therapy periods, the computer training combined with occlusion was found to be about twice as effective as the preceding occlusion alone. The results of combined computer training and occlusion show an additional increase of the same amount as the preceding occlusion alone, which yielded at its end no further advantage to the development of visual acuity in the selected sample of our 55 therapy-resistant patients. In a concluding theoretical note, a preliminary

    Purpose/Objective(s): Mature data on tumor control and survival are presented from a randomized trial of the addition of a brachytherapy boost to long-course neoadjuvant chemoradiation therapy (CRT) for locally advanced rectal cancer. Methods and Materials: Between March 2005 and November 2008, 248 patients with T3-4N0-2M0 rectal cancer were prospectively randomized to either long-course preoperative CRT (50.4 Gy in 28 fractions, per oral tegafur-uracil and L-leucovorin) alone or the same CRT schedule plus a brachytherapy boost (10 Gy in 2 fractions). The primary trial endpoint was pathologic complete response (pCR) at the time of surgery; secondary endpoints included overall survival (OS), progression-free survival (PFS), and freedom from locoregional failure. Results: Results for the primary endpoint have previously been reported. This analysis presents survival data for the 224 patients in the Danish part of the trial. In all, 221 patients (111 control arm, 110 brachytherapy boost arm) had data available for analysis, with a median follow-up time of 5.4 years. Despite a significant increase in tumor response at the time of surgery, no differences in 5-year OS (70.6% vs 63.6%, hazard ratio [HR] = 1.24, P=.34) and PFS (63.9% vs 52.0%, HR=1.22, P=.32) were observed. Freedom from locoregional failure at 5 years were 93.9% and 85.7% (HR=2.60, P=.06) in the standard and in the brachytherapy arms, respectively. There was no difference in the prevalence of stoma. Explorative analysis based on stratification for tumor regression grade and resection margin status indicated the presence of response migration. Conclusions: Despite increased pathologic tumor regression at the time of surgery, we observed no benefit on late outcome. Improved tumor regression does not necessarily lead to a relevant clinical benefit when the neoadjuvant treatment is followed by high-quality surgery.

    Full Text Available AIM: To assess the refractive outcome of clear lensectomy combined with piggyback intraocular lens implantation in highly hyperopic patients.METHODS: This case review included 19 eyes of 10 patients with high hyperopia and axial length less than 21mm. Intraocular lens power was calculated for emmetropia using the Holladay II formula in 17 eyes, and SRK/T formula in 2 eyes following clear lens extraction and piggyback intraocular lens implantation. Patients were examined periodically over 24 months for visual acuity and spherical equivalent (SE.RESULTS: The mean postoperative SE at 24 months was 0.20±1.39D (range, -3.00 to 2.50D, better than preoperative 9.81±2.62D (range, +6.00 to +14.50D (PPP=0.34. Twelve eyes maintained and 1 gained 1 or more Snellen line of BCVA, 4 eyes lost 1 line, and 2 eyes lost 2 lines at 24 postoperative months. Twelve eyes best-corrected near visual acuity (BCNVA achieved J1 at postoperative 24 months compared to preoperative 7 eyes and the other 7 eyes better than J3.CONCLUSION: Clear lens extraction combined piggyback intraocular lens implantation appears to be an effective procedure to correct high hyperopia but mild overcorrection and intralenticular opacification may require secondary procedure.

    Full Text Available OBJECTIVE: We have measured the concentration of immunoreactive neutrophil elastase (ir-NE in the tumor extracts of 313 primary human breast cancers. Sufficient time has elapsed, and we are now ready to analyze its prognostic value in human breast cancer. METHODS: ir-NE concentration in tumor extracts was determined with an enzyme-linked immunosorbent assay that enables a rapid measurement of both free-form ir-NE and the α1-protease inhibitor-complexed form of ir-NE. We analyzed the prognostic value of this enzyme in human breast cancer in univariate and multivariate analyses. RESULTS: Patients with breast cancer tissue containing a high concentration of ir-NE had poor survival compared to those with a low concentration of ir-NE at the cutoff point of 9.0 µg/100 mg protein (P = .0012, which had been previously determined in another group of 49 patients. Multivariate stepwise analysis selected lymph node status (P= .0004; relative risk = 1.46 and ir-NE concentration (P= .0013; relative risk = 1.43 as independent prognostic factors for recurrence. CONCLUSIONS: Tumor ir-NE concentration is an independent prognostic factor in patients with breast cancer who undergo curative surgery. This enzyme may play an active role in tumor progression that leads to metastasis in human breast cancer.

    Although fludarabine, cyclophosphamide, and rituximab (FCR) together are established as a standard first-line treatment of younger patients with chronic lymphocytic leukemia (CLL), there is little information to guide the management of patients with CLL refractory to, or who have relapsed after, receiving frontline FCR treatment. To define optimal salvage strategy and identify patients unsuitable for retreatment with FCR, we examined the survival and treatment outcome of 300 patients enrolled in a phase 2 study of FCR. After a median 142 months of follow-up, 156 patients developed progressive CLL, with a median survival of 51 months after disease progression. The duration of first remission (REM1) was a key determinant of survival after disease progression and first salvage. Patients with a short REM1 (<3 years) had a short survival period, irrespective of salvage therapy received; these patients have high unmet medical needs and are good candidates for investigation of novel therapies. In patients with a long REM1 (≥3 years), salvage treatment with either repeat FCR or lenalidomide-based therapy results in subsequent median survival exceeding 5 years; for these patients, FCR rechallenge represents a reasonable standard of care.

    Background/Aims Lanthanum carbonate (LC, FOSRENOL®) is an effective phosphate binder for which tolerability and a safety profile have been reported in haemodialysis patients. Patients from previous studies entered a 2-year extension, enabling assessment of efficacy and safety for up to 6 years of LC monotherapy. Methods Patients from four previous trials entered this study. Results Ninety-three patients started the extension, with 22 entering a sixth year of LC treatment. Two-thirds of all patients received LC doses of 2,250 or 3,000 mg/day. Reductions in serum phosphate and calcium × phosphate product were maintained for up to 6 years. There were no new or unexpected adverse events (AEs), and no increase in the incidence of events with increasing treatment exposure. Over the complete duration of therapy, treatment-related AEs occurred in 25.8% of patients and were primarily gastrointestinal in nature. No clinically relevant changes in liver function tests were observed and there was no evidence of adverse effects on the liver, bone or the central nervous system. Conclusions LC monotherapy was effective and well tolerated for up to 6 years with no evidence of safety concerns or increased frequency of AEs. PMID:18667837

    We present the results of a study of the low-mass X-ray binary 4U 1636-536. We have performed temporal analysis of all available RXTE/ASM, Swift/BAT and MAXI data. We have confirmed the previously discovered quasi-periodicity of ~45 d present during ~2004, however we found it continued to 2006. At other epochs, the quasi-periodicity is only transient, and the quasi-period, if present, drifts. We have then applied a time-dependent accretion disc model to the interval with the significant X-ray quasi-periodicity. For our best model, the period and the amplitude of the theoretical light curve agree well with that observed. The modelled quasi-periodicity is due to the hydrogen thermal-ionization instability occurring in outer regions of the accretion disc. The model parameters are the average mass accretion rate (estimated from the light curves), and the accretion disc viscosity parameters, for the hot and cold phases. Our best model gives relatively low values of viscosity parameter for cold phase 0.01 and for h...

    We present the results of a study of the low-mass X-ray binary 4U 1636-536. We have performed temporal analysis of all available RXTE/ASM, RXTE/PCA, Swift/BAT and MAXI data. We have confirmed the previously discovered quasi-periodicity of ˜45 d present during ˜2004, however we found it continued to 2006. At other epochs, the quasi-periodicity is only transient, and the quasi-period, if present, drifts. We have then applied a time-dependent accretion disc model to the interval with the significant X-ray quasi-periodicity. For our best model, the period and the amplitude of the theoretical light curve agree well with that observed. The modelled quasi-periodicity is due to the hydrogen thermal-ionization instability occurring in outer regions of the accretion disc. The model parameters are the average mass accretion rate (estimated from the light curves), and the accretion disc viscosity parameters, α_{cold} and α_{hot}, for the hot and cold phases, respectively. Our best model gives relatively low values of α_{cold} and α_{hot}.

    Cancer is a multifactorial disease and skin carcinomas are the most common type of cancer. Assessing quality of life and self-esteem outcomes in skin cancer patients is important because these are indicators of the results of the treatment, translating how patients face their lives and their personal relationships. To assess the late impact of the surgical treatment of head and/or neck skin carcinomas on quality of life and self-esteem of the patients. Fifty patients with head or neck skin carcinomas were enrolled. Their age ranged between 30 and 75 years, 27 were men and 23 were women. Patients were assessed with regard to quality of life and self-esteem, preoperatively and five years postoperatively. Validated instruments were used: the MOS 36-item Short-form Health Survey (SF-36) and the Rosenberg Self-esteem/EPM-UNIFESP Scale. The Wilcoxon signed-rank test was used for the statistical analysis. Twenty-two patients completed the five-year follow-up, 54.5% women and 45.5% men. Compared to the preoperative assessment, patients had an improvement in mental health (p=0.011) and in self-esteem (p=0.002). There was no statistical difference with regard to the other domains of the SF-36. Patients submitted to surgical treatment of skin carcinoma improved mental health and self-esteem in the late postsurgical testing.

    The aim of this study was to examine the photographic and radiographic success of the treatment of maxillary anterior primary incisors with composite resin strip crowns (SCs) placed in a private-practice setting after a minimum of 18 months. This was a retrospective, clinical study of patients who had SCs placed on primary maxillary incisors, returned for at least one 18-month recall examination, and whose parents consented to participate in the study. Radiographic and photographic examinations were used for evaluation. Two evaluators rated the images independently. One hundred forty-five restorations, placed in 52 children, were evaluated. The evaluations were performed after the crowns had been in place for an average of 31.3 months. None of the restorations were totally lost: 20% were rated as having lost some resin material, resulting in an 80% overall retention rate; 92% of the teeth demonstrated healthy pulps; 6% had some pulpal changes, but did not require immediate attention. Only 2 teeth showed radiographic evidence of pulpal pathology requiring treatment. SCs performed well for restoring primary incisors with large or multisurface caries for periods of over 3 years. This study suggests that SCs are likely to be successful and may be indicated as an excellent treatment choice for carious primary incisors with adequate tooth structure after caries removal, especially if esthetic concerns predominate.

    The first author has been using an autogenous cortical bone columella to replace the stapes removed during stapedectomy since 1965. The audiograms of 21 of the 271 patients operated on with this method between 1965 and 1989 (i.e. 7.7% of the possible candidates) were available 20-35 (average 26.8) years postoperatively. The operation could be regarded as successful in 20 and unsuccessful in 1 patient in the long run. The audiological data are presented individually as averages of the values obtained at 0.5, 1, 2 and 3 kHz. The averaged data (n = 21): preoperative air conduction, 58.27; bone conduction, 24.46; and air-bone gap, 33.81 dB. Postoperative best air conduction, 19.07; bone conduction, 14.10; and air-bone gap, 4.97 dB. Postoperative recent air conduction, 45.77; bone conduction, 38.45; and air-bone gap, 7.32 dB. The best values were measured 1-8 (average 1.57) years postoperatively. In relation to the postoperative best value, the recent value of the air-bone gap had deteriorated by 2.35 dB, and that of the bone conduction by 24.35 dB. The small air-bone gap indicates that the deterioration of the hearing is mainly caused by the deterioration of the function of the inner ear and not by that of the conductive apparatus. The progression of the deterioration differs individually (0.3-1.6, average 0.93 dB/year) and accelerates with age. This finding seems to be a problem that does not depend on the operative technique. The data show that the autogenous bone columella ensures the same good and lasting results as the alloplastic solutions; moreover, there is no problem with the incus-prosthesis connection.

    Full Text Available Small aquatic ecosystems of the boreal zone are known to be most sensitive indicators of on-going environmental change as well as local anthropogenic pressure, while being highly vulnerable to external impacts. Compared to rather detailed knowledge of the evolution of large and small lakes in Scandinavia and Canada, and large lakes in Eurasia, highly abundant small boreal lakes of northwest Russia have received very little attention, although they may become important centers of attraction of growing rural population in the near future. Here we present the results of a multidisciplinary, multi-annual study of a small boreal humic lake of NW Russia. A shallow (3 m and a deep (16 m site of this lake were regularly sampled for a range of chemical and biological parameters. Average multi-daily, summer-time values of the epilimnion (upper oxygenated layer of the lake provided indications of possible trends in temperature, nutrients, and bacterio-plankton concentration that revealed the local pollution impact in the shallow zone and overall environmental trend in the deep sampling point of the lake. Organic phosphorus, nitrate, and lead were found to be most efficient tracers of local anthropogenic pollution, especially visible in the surface layer of the shallow site of the lake. Cycling of trace elements between the epilimnion and hypolimnion is tightly linked to dissolved organic matter speciation and size fractionation due to the dominance of organic and organo-ferric colloids. The capacity of lake self-purification depends on the ratio of primary productivity to mineralization of organic matter. This ratio remained >1 both during winter and summer periods, which suggests a high potential of lake recovery from the input of allochthonous dissolved organic matter and local anthropogenic pollution.

    The important role of tropical forests in the global carbon cycle makes it imperative to assess changes in their carbon dynamics for accurate projections of future climate-vegetation feedbacks. Forest monitoring studies conducted over the past decades have found evidence for both increasing and decreasing growth rates of tropical forest trees. The limited duration of these studies restrained analyses to decadal scales, and it is still unclear whether growth changes occurred over longer time scales, as would be expected if CO2 -fertilization stimulated tree growth. Furthermore, studies have so far dealt with changes in biomass gain at forest-stand level, but insights into species-specific growth changes - that ultimately determine community-level responses - are lacking. Here, we analyse species-specific growth changes on a centennial scale, using growth data from tree-ring analysis for 13 tree species (~1300 trees), from three sites distributed across the tropics. We used an established (regional curve standardization) and a new (size-class isolation) growth-trend detection method and explicitly assessed the influence of biases on the trend detection. In addition, we assessed whether aggregated trends were present within and across study sites. We found evidence for decreasing growth rates over time for 8-10 species, whereas increases were noted for two species and one showed no trend. Additionally, we found evidence for weak aggregated growth decreases at the site in Thailand and when analysing all sites simultaneously. The observed growth reductions suggest deteriorating growth conditions, perhaps due to warming. However, other causes cannot be excluded, such as recovery from large-scale disturbances or changing forest dynamics. Our findings contrast growth patterns that would be expected if elevated CO2 would stimulate tree growth. These results suggest that commonly assumed growth increases of tropical forests may not occur, which could lead to erroneous

    Lianas are a prominent growth form in tropical forests, and there is compelling evidence that they are increasing in abundance throughout the Neotropics. While recent evidence shows that soil resources limit tree growth even in deep shade, the degree to which soil resources limit lianas in forest understories, where they coexist with trees for decades, remains unknown. Regardless, the physiological underpinnings of soil resource limitation in deeply shaded tropical habitats remain largely unexplored for either trees or lianas. Theory predicts that lianas should be mor
