    A large aneurysm of the left renal artery was found incidentally during abdominal ultrasound in a 39-year-old woman with no medical or family history of cardiovascular disease. Vascular pathology with a dysplastic appearance was confirmed by magnetic resonance angiography and the patient was offered transcatheter embolization. Since the position and size of the neck of the aneurysm could not be determined at angiography, detachable platinum coils were used for occlusion. The procedure was performed without complications. During a 4-year follow-up no alterations of renal function, recanalization of the aneurysm, or perfusion defects in the rest of the left renal circulation were noted.

    Aim: To audit the safety of day-case peripheral arterial intervention without the use of arterial-closure devices using nurse-led admission, discharge, and follow-up procedures. Materials and methods: Patients referred for elective, peripheral vascular intervention were selected for day-case care according to pre-determined criteria using telephone triage. Post-procedure haemostasis was achieved using manual compression. After 3 h bed-rest, patients were mobilized and discharged at 5 h. Patients were contacted by telephone next working day to audit complications. Results: One hundred and eighty-three elective day-case peripheral interventions were performed over 2 years, predominantly using 6 F sheaths. No closure devices were used. Five patients (2%) returned to the department because of persistent groin symptoms the next day. One of these had a false aneurysm. Four required no further treatment. A single patient returned at day 6 with a delayed false aneurysm. Conclusion: Day-case peripheral vascular intervention can be safely performed in appropriately selected patients without the use of arterial closure devices. Specialist radiology nurses have a major role in the counselling, care, and follow-up of these patients.

    Purpose. This prospective study was undertaken to determine the success rate, complications, and outcome of carotid artery stenting (CAS) without the use of cerebral protection devices. Methods. During 12 months, 94 high-grade stenoses of the carotid artery in 91 consecutive patients were treated. Sixty-six (70%) of the stenoses were symptomatic and 28 (30%) were asymptomatic. Results. In all 94 carotid stenoses CAS was successfully performed. During the procedure and within the 30 days afterwards, there were 2 deaths and 3 major strokes in the 66 symptomatic patients, resulting in a combined death and stroke rate of 5 of 66 (7%). Only one of these complications, a major stroke, occurred during the procedure. In the 6-month follow-up, one additional major stroke occurred in a originally symptomatic patient resulting in a combined death and stroke rate of 6 of 66 (10%) for symptomatic patients at 6 months. No major complications occurred in asymptomatic patients during the procedure or in the 6-month follow-up period. At 6 months angiographic follow-up the restenosis rate with a degree of >50% was 3 of 49 (6%) and the rate with a degree of ≥70% was 1 of 49 (2%). Conclusions. Cerebral embolization during CAS is not the only cause of the stroke and death rate associated with the procedure. The use of cerebral protection devices during the procedure may therefore not prevent all major complications following CAS

    Objective To evaluate the long-term anatomic results of renal revascularization procedures using duplex ultrasonography. Design A case series. Setting A university-affiliated hospital. Patients Twenty-five patients who had undergone renal percutaneous transluminal angioplasty (PTA) (18 arteries), renal bypass (10 arteries) and mesenteric bypass (6 arteries). The mean follow-up was 22 months (range from 3 to 48 months) for those who underwent renal PTA, 23 months (range from 1.5 to 70 months) for those who underwent renal bypass and 34 months (range from 8 to 144 months) for those who underwent mesenteric bypass. Main Outcome Measures Patency rates for the three procedures as assessed by duplex ultrasonography. Results Duplex ultrasonography demonstrated patency without stenosis after renal and mesenteric artery revascularization in 14 arteries subjected to renal PTA, 9 arteries subjected to renal bypass and 6 arteries subjected to mesenteric bypass. Three arteries that had renal PTA had recurrent vessel stenosis and one had occlusion. One artery that had renal bypass showed occlusion. Conclusions Renal PTA, renal bypass and mesenteric bypass are durable procedures at 2 years of follow-up, and duplex ultrasonography is a valuable method for assessing the patency of arteries after renal and mesenteric revascularization.

    Full Text Available Introduction : Fifty percent of cases of peripheral artery disease are caused by chronic total occlusion (CTO of the superficial femoral artery (SFA. Ten–fifteen percent of percutaneous SFA recanalization procedures are unsuccessful. In those cases the retrograde technique can increase the success rate of the procedure, but the long-term follow-up of such procedures is still unknown. Aim : To assess the efficacy and clinical outcomes during long-term follow-up after retrograde recanalization of the SFA. Material and methods: We included patients after at least one unsuccessful percutaneous antegrade recanalization of the SFA. Patients were evaluated for the procedural and clinical follow-up of mean time 13.9 months. Results: The study included 17 patients (7 females, 10 males who underwent percutaneous retrograde recanalization of the SFA from June 2011 to June 2015. The mean age of patients was 63 ±7 years. Retrograde puncture of the distal SFA was successful in all cases. A retrograde procedure was performed immediately after antegrade failure in 4 (23.5% patients and after a previously failed attempt in 13 (76.5% patients. The procedure was successful in 15 (88.2% patients, and unsuccessful in 2 (11.8% patients. Periprocedural complications included 1 peripheral distal embolization (successfully treated with aspiration thrombectomy, 1 bleeding event from the puncture site and 7 puncture site hematomas. During follow-up the all-cause mortality rate was 5.8% (1 patient, non-cardiac death. The primary patency rate at 12 months was 88.2% and secondary patency 100%. Conclusions : The retrograde SFA puncture seems to be a safe and successful technique for CTO recanalization and is associated with a low rate of perioperative and long-term follow-up complications.

    Arterial hypertension is the most common cardiovascular system disease, affecting nearly one billion people worldwide. Despite the widespread use of antihypertensive medications, in some groups of patients an optimal blood pressure (BP) cannot be achieved. To assess BP reduction in patients with resistant hypertension after a catheter-based renal sympathetic denervation procedure and to report vascular and kidney safety in one-year follow-up. Twenty eight patients with diagnosed resistant hypertension (median age 52.02 years, range 42-72) underwent percutaneous catheter-based renal denervation of nerve terminals in renal arteries. Arterial angiography and procedure of ablation was performed by Symplicity catheters and generator provided by Ardian (currently Medtronic Inc., USA). Mean BP value before ablation was [mm Hg]: systolic 176.6, diastolic 100.28 and pulse pressure 73.4. After the procedure, reductions in the value of BP were reported [mm Hg]: systolic 154.8/152.54; diastolic 90.2/89.8, pulse pressure 64.66/62.73, respectively in nine-month and one-year follow-up. All results were statistically significant. No complications during one year observation were observed. Percutaneous renal artery ablation procedure effectively reduces systolic BP, diastolic BP, and pulse pressure. No vascular or renal complications in any of the patients were observed. The results of a Polish research group showed no significant differences compared to the results obtained in the international studies Symplicity I and Symplicity II.

    To analyse prospectively results of HAL-RAR technique by evaluating pain, perioperative complications and clinical outcome after two years followup. A prospective study design including 30 consecutive patients with haemorrhoids grade III-IV treated from June 2012. After discharge, patients received a specific questionnaire to record postoperative pain, delayed complications, evolution/disappearance of the symptoms that led to the surgical intervention (bleeding, prolapse, itching, pain and soiling). A visual analog scale (VAS) was used to measure pain. Outpatient follow-up was carried out at 7 days, and 1, 6 and 12 months and annually thereafter. Pre, intra and postoperative data (including physical examination) had been recorded prospectively. The median operating time (range) was 40 (26-60) minutes. Average hospital stay (range) was 11 (3-25) hours. No postoperative complications were observed in 29 cases (96.6%). Median follow-up was 26 (12-36) months. All the patients attended the follow-up. Mean postoperative pain was VAS = 1.7 on the seventh day and it was practically non-existent (VAS = 0.7) 1 month after the procedure. 87.5% of patients confirmed complete relief of symptoms after 30 days and 93% of patients feel free of symptoms 6 months after the procedure. No patient has experienced late complications as dyschezia, urgency, soiling or faecal incontinence. After 24 months follow-up, recurrence of bleeding and prolapse was observed in only 1 patient; 93% of patients have considered results of HAL-RAR as very good or excellent. HAL-RAR is safe and almost painless technique and it has very good results in the control of haemorrhoidal symptoms. This procedure should be considered as an effective first treatment option for haemorrhoids. Copyright © 2016 IJS Publishing Group Limited. Published by Elsevier Ltd. All rights reserved.

    Use of the left internal mammary artery to bypass the left anterior descending coronary artery reduces cardiac events and increases survival. However, there is some controversy as to the benefits of using both mammary arteries. To assess the long-term outcome of the use of both mammary arteries in comparison with the use of only one. A retrospective cohort study with a mean follow-up of 9.0 +/- 4.2 years was performed including 108 patients consecutively revascularized using both mammary arteries (II) and 108 patients randomly chosen in whom one mammary artery (I) was used for this purpose. Both groups were similar. There were no differences between the groups in operative morbidity or mortality. The survival at 10 years was similar (II: 84.61 +/- 4%; I: 85.18 +/- 3.8%), whereas recurrence of angina (II: 29.63 +/- 5.3%; I: 47.55 +/- 5.6%) (p = 0.012), the requirement for percutaneous angioplasty (II: 3.98 +/- 2%; I: 12.99 +/- 4.1%) (p = 0.009) and cardiologic events (II: 33.48 +/- 5.5%; I: 48.48 +/- 5.5%)(p = 0.022) were all lower in the group in which both mammary arteries were used. In the multivariate analysis, the use of both mammary arteries was an independent protective factor against angina recurrence (RR = 0.55), angioplasty (RR = 0.18) and cardiologic event (RR = 0.60). The use of both mammary arteries for revascularization does not increase operative morbidity. Since this procedure acts as an independent factor against angina recurrence, angioplasty and cardiologic event

    Objective: To evaluate the efficacy and mid-term follow-up results of endovascular treatment with Willis covered stent for traumatic pseudoaneurysms located in the internal carotid artery (ICA). Methods: ICA angiography was performed in 38 patients with traumatic brain and neck injury. Of the 38 patients, 13 delayed traumatic pseudoaneurysms were found. All the pseudoaneurysms were treated with Willis covered stents. Follow-up angiography was performed at 1, 3, 6 and 12 months after the procedure, and the results were categorized as complete or incomplete occlusion. Clinical manifestations were graded as full recovery, improvement, unchanged and aggravation. Results: Willis covered stent placement was technically successful in all traumatic pseudoaneurysms. No procedure-related complications occurred. The initial angiographic results showed a complete occlusion in 9 patients, and an incomplete occlusion in 4. The angiographic follow-up within 3-12 months exhibited a complete occlusion in 12 patients and the parent arteries remained patency in all patients. The clinical follow-up observation demonstrated that full recovery was obtained in 11 patients, clinical improvement in one, and unchanged condition in one. No morbidity or mortality occurred. Conclusion: Willis covered stent implantation is a feasible and practical treatment for traumatic pseudoaneurysms located in the ICA. This technique can well preserve the parent artery with excellent therapeutic results. (authors)

    Full Text Available The purpose of this study was to evaluate the efficacy and long-term complications of internal iliac artery embolization as a palliative measure in the control of intractable hemorrhage from advanced bladder malignancy. From January 1998 through December 2005, seven patients underwent transcatheter arterial embolization (TAE of anterior division of internal iliac artery bilaterally for intractable bladder hemorrhage. After embolization, patients were followed for the efficacy of the procedure in controlling hematuria and complications. TAE was successful in immediate control of severe hemorrhage in all seven patients after a mean period of 4 days. At a mean (range follow-up of 10 (6–12 months, the hemorrhage was permanently controlled in four (57% patients. Three patients developed hematuria and required emergency admissions; two had mild hematuria and were managed conservatively, and the remaining one required a second attempt of embolization after 2 months from the first one. During the whole period of follow-up, there were no significant complications related to embolization. Internal iliac artery embolization is an effective and minimally invasive option when managing advanced bladder malignancies presenting with intractable bleeding. The long-term follow-up showed control of bleeding in the majority of such patients with no serious complications.

    AIM: To investigate the clinical value and audit chest radiography, which is currently undertaken as part of routine practice, in the follow-up of coronary artery bypass graft (CABG) patients. MATERIAL AND METHODS: Six hundred and sixty-six first time CABG patients were identified from the Patient Analysis and Tracking System database representing the work of a single surgeon between February 2001 and September 2005. The data regarding the clinical and radiological findings on follow-up were collected from the follow-up clinic letters and case notes. Any need for re-admission/intervention was also noted. RESULTS: Of the 666 patients, 11 died and a further 10 either refused or failed to arrive for follow-up. Chest radiography was undertaken in 645 patients. Only 13 patients (2%) were found to have an abnormality on chest radiography. In all cases this was a pleural effusion that was confirmed on clinical examination in seven patients (53.9%) patients. Only one patient needed re-admission and intervention. In this case the effusion had been noted on clinical examination. Seven patients were discharged and the remaining five were followed up with repeat chest radiography before discharge. Seventy-four patients had a respiratory complication postoperatively, but only three had any evidence of an effusion on follow-up. CONCLUSION: The diagnostic yield of a routine chest radiography in a CABG follow-up clinic is low (2%) and the need for intervention is rare and is determined by clinical examination. The practice of routine radiography in this group of patients has now stopped and follow-up audit will be conducted in 12 months.

    Objective: To investigate the effect of renal artery revascularization through renal artery stenting(PTRAS)on blood pressure in patients with renal artery stenosis. Methods: During April 2000 through May 2005 110 cases of renal artery stenosis received PTRAS and followed up for at least 1 year with blood pressure measurements pre-and 1 year post-PTRAS. Results: The technical success rate was 100% for all 110 cases. The renal artery stenosis were decreased from 60%-100% before PTRAS to 0%-15% after the stent placement. There was significant difference between blood pressure pre-and 1 year post PTRAS. Systolic pressures decreased from(153 ± 32) mmHg to(131 ± 27) mmHg and diastolic pressures from(87 ± 19) mmHg to(75 ± 19) mmHg. The administration of antihypertensive diugs reduced from(2.6 ± 0.9 ) sorts to(1.9 ± 0.9) sorts. Conclusions: PTRAS revascularization is an effective procedure for blood pressure control in renal vascular hypertension during one year follow up. (authors)

    Full Text Available Purpose: To present the long-term effect of intravitreal bevacizumab (Avastin® therapy in a patient suffering from retinal arterial macroaneurysm. Methods: Case report of a 72-year-old female diagnosed with retinal macroaneurysm in the superior temporal artery leading to macular edema. Functional and morphological data at baseline, 4 weeks, 2 months, and 13 months following treatment with two consecutive intravitreal bevacizumab injections are presented. Results: Best-corrected visual acuity improved from 20/160 at baseline to 20/20 at the3-months follow-up and remained stable through 13 months of follow-up. Central retinal thickness measured by optical coherence tomography decreased from 364 µm at baseline to 248 µm at the 13-months follow-up. No ocular or systemic side effects were detected. Conclusions: Intravitreal bevacizumab therapy may lead to resolution of macular edema associated with retinal macroaneurysm and consequently visual improvement. This treatment may promise a long-lasting effect but warrant further investigation in larger series.

    In symptomatic patients with hypothenar hammer syndrome, the occluded part of the ulnar artery can be reconstructed with an autologous graft. Venous grafts are used frequently, but they are known for their low patency rate. Arterial grafts show better patency rates than venous grafts in coronary bypass surgery. We performed 11 ulnar artery reconstructions with the descending branch of the lateral circumflex femoral artery and compared these with previously performed venous reconstructions. All patients with an arterial graft reconstruction had a patent graft at a mean follow-up of 63 months. In addition, nine out of 11 patients reported improvement in their symptoms. The patency rate of venous reconstructions in hypothenar hammer syndrome is significantly lower. Arterial grafting for hypothenar hammer syndrome has superior patency compared with venous grafting; we recommend it as the surgical treatment of choice for symptomatic hypothenar hammer syndrome. 4.

    Objective: To observed the long-term follow-up of the two types of interventional procedure for achalasia. Methods: The study cohort was comprised of 140 patients of achalasia including 70 patients treated under fluoroscopy with pneumatic dilation (group A) and 70 with temporary partially covered metal stent dilation (group B). Results: One hundred and forty dilations were performed on the 70 patients of group A with complications of chest pain (n=35), reflux (n=18), and bleeding (n=8); 38 patients of relapsing dysphagia during a 12-month follow-up, and 50 patients out of 60 of recurrent dysphagia during a 36-month follow-up. Seventy partially covered expandable metal stents were temporarily placed in the 70 patients of group B and withdrawn after 3-7 days via gastroscopy with complications of chest pain (n=28), reflux (n=15), and bleeding (n=9); 7 patients out of 70 exhibited dysphagia relapse during a 12-month followup, and 9 out of 58 patients exhibited dysphagia relapse during a 36-month follow-up. All the stents were inserted and withdrawn successfully. The follow-up in groups A-B lasted for 12-96 months. Conclusion: Temporary partially covered metal stent dilation is one of the best methods of interventional procedure for achalasia in long-term follow-up. (authors)

    Follow-up habitat evaluation procedures (HEP) analyses were conducted on the Dormaier and Chester Butte wildlife mitigation sites in April 2007 to determine the number of additional habitat units to credit Bonneville Power Administration (BPA) for providing funds to enhance, and maintain the project sites as partial mitigation for habitat losses associated with construction of Grand Coulee Dam. The Dormaier follow-up HEP survey generated 482.92 habitat units (HU) or 1.51 HUs per acre for an increase of 34.92 HUs over baseline credits. Likewise, 2,949.06 HUs (1.45 HUs/acre) were generated from the Chester Butte follow-up HEP analysis for an increase of 1,511.29 habitat units above baseline survey results. Combined, BPA will be credited with an additional 1,546.21 follow-up habitat units from the Dormaier and Chester Butte parcels.

    Introduction: Long-term results of uterine artery embolization (UAE) for adenomyosis are largely unknown. We assess long-term outcome of UAE in 40 women with adenomyosis. Materials and methods: Between March 1999 and October 2006, 40 consecutive women with adenomyosis (22 in combination with fibroids) were treated with UAE. Changes in junction zone thickness were assessed with magnetic resonance imaging (MRI) at baseline and again at 3 months. After a mean clinical follow-up of 65 months (median 58 [range 38–129]), women filled out the uterine fibroid symptom and quality of life (UFS-QoL) questionnaire, which had additional questions on the long-term evolution of baseline symptoms and adverse events. Results: During follow-up, 7 of 40 women (18%) underwent hysterectomy. Among these 7 women, the junction zones were significantly thicker, both at baseline (mean 23 vs. 16 mm, P = 0.028) and at 3-month follow-up (mean 15 vs. 9 mm, P = 0.034). Of 33 women with preserved uterus, 29 were asymptomatic. Four patients had symptom severity scores of 50 to 85 and overall QoL scores of 60 to 66, indicating substantial clinical symptoms. There was no relation between clinical outcome and the initial presence of fibroids in addition to adenomyosis. Conclusion: In women with therapy-resistant adenomyosis, UAE resulted in long-term preservation of the uterus in the majority. Most patients with preserved uterus were asymptomatic. The only predictor for hysterectomy during follow-up was initial thickness of the junction zone. The presence or absence of fibroids in addition to adenomyosis had no relation with the need for hysterectomy or clinical outcome.

    The study's purpose is to report the technical and clinical outcomes of a patient cohort that underwent vertebral artery ostium stent placement for atherosclerotic stenosis. We retrospectively analyzed a prospectively collected database of neurointerventional procedures performed at a single center from 1999 to 2005. Outcome measures included recurrent transient neurological deficits (TNDs), stroke, and death. Kaplan-Meier analysis was used to estimate stroke- and/or death-free survival at 12 months. Cox proportional hazard was used to identify risk factors for recurrent vertebrobasilar ischemic events. Seventy-two patients with 77 treated vertebral ostial lesions were included. The 30-day stroke and/or death rate was 5.2% (n = 4), although no event was directly related to the vertebral ostium stent placement. Three procedure-related strokes were secondary to attempted stent placement at other sites (one carotid artery and two basilar arteries), and the one death was secondary to the presenting stroke severity. The mean clinical follow-up time available for 66 patients was 9 months. There were 14 TNDs (21%), two strokes (3%), and two deaths (3%) recorded in the follow-up. Recurrent vertebrobasilar ischemic events occurred in nine patients (seven TNDs and two strokes). No recurrent stroke and/or deaths were related to the treated vertebral ostium. Stroke- and/or death-free survival rate (including periprocedural stroke and/or death) was 89 ± 5% at 12 months. No vascular risk factor was significantly associated with recurrent vertebrobasilar ischemic events. Vertebral artery ostium stent placement can be safely and effectively performed with a low rate of recurrent stroke in the territory of the treated vessel. Patients who also underwent attempted treatment of a tandem intracranial stenosis appeared to be at highest risk for periprocedure stroke. (orig.)

    This study was designed to see the long and short term outcome of the reverse sural artery flap. Study Design: Case series. Patients and Methods: From January 2009 to December 2011, data was collected and analyzed for this study.Eighty nine patients with wounds on the ankle, heel, sole, distal leg, and foot were included in the study. They were followed up at 01 week, 02 weeks, and then 4 weekly for 06 months and at one year time from operation. They were examined for necrosis, congestion, surgical site infection, dehiscence of suture line, epidermolysis, donor site infection and functional outcome. Results: Most of the flaps healed nicely but two (2.25%) failed completely. Six flaps were delayed. However early follow up (within 04 weeks) revealed that there was partial loss of the distal 1-1.5 cm of flap in 04 patients (4.50%). Two patients (2.25%) developed superficial surgical site infection. Six patients (6.74%) developed venous congestion of the flaps which recovered within two weeks. Other minor complications included dehiscence of suture line in 3 patients (3.37%), and superficial Epidermolysis in four (4.50%) (Table-2). Twenty two patients (24.72%) returned to their work in 12-16 weeks, 31 (34.83%) in 16-20 weeks and 36 (40.45%) in 20-24 weeks. Long term follow-up to 06 months revealed hypertrophic scars at the donor site in three patients (4.91%) and recurrence of ulcer in 2 patients (3.27%). Conclusion: The sural fasciocutaneous flap provides reliable supple and durable most single-stage coverage of wounds of the distal third of the leg, heel, and foot with the results comparable to free-tissue transfer.

    The aim of this study is to describe the procedure technique, clinical and imaging outcomes of patients treated with radiofrequency ablation for chondroblastoma. Four patients (female/male, 3:1; mean age, 13 years; age range; 9-16 years) underwent the procedure. All had pre-operative magnetic resonance imaging (MRI) and symptomatic, biopsy-proven chondroblastomas (two proximal femur, two proximal tibia). The lesion size ranged from 1.5 to 2.5 cm in maximal dimension (mean size, 1.8 cm). Bone access was gained with a Bonopty biopsy needle system (mean number of radiofrequency needle placements, 5; mean ablation time, 31 min). Clinical and MRI follow-up was available in all cases (mean, 12.25 months; range, 5-18 months). All patients reported resolution of symptoms at 2-6 weeks post ablation. At their most recent clinical follow-up, three patients remained completely asymptomatic with full return to normal activities and one patient had minor local discomfort (different pain pattern) that was not limiting activity. All four patients' follow-up MRI studies demonstrated resolution of the oedema pattern around the lesion and temporal evolution of the internal signal characteristics with fatty replacement. Radiofrequency ablation for chondroblastoma provides an alternative to surgical curettage, and we have demonstrated both a clinical improvement in symptoms and the follow-up MRI appearances. (orig.)

    Full Text Available Objectives: Transposition of Great Arteries (TGA is a serious congenital heart disease and anatomic correction in the first few weeks of life has revealed good outcomes nowadays. In this study, we aimed to evaluate the myocardial and valvular function at midterm postoperative follow-up. Patients and Methods: In this study, thirty-three patients with TGA and Arterial Switch Operation (ASO were evaluated by 2-dimensional, M-mode, Doppler, and pulsed Tissue Doppler. These patients were compared with 33 healthy children of the same age and gender as the normal control group. Student’s t-test and Pearson correlation were used to analyze the data. Besides, P<0.05 was considered as statistically significant. Results: The mean follow up time was 40.9±5.6 months. Among the 33 patients with ASO, 6% had mild pulmonary stenosis, while 3% had mild pulmonary insufficiency. Aortic stenosis and aortic insufficiency of trivial to mild degree was seen in 12% and 12% of the patients, respectively. The patients’ systolic velocity of tricuspid (S, early diastolic velocity of tricuspid (Ea, and late velocity of tricuspid valve (Aa were significantly different from those of the controls (P<0.001. Also, pulmonary annulus diameter was significantly dilated in the patients compared to the controls (1.67±0.41 vs. 1.29±0.28, P≤0.001. Besides, aortic annulus diameter (1.56±0.42 vs. 1.24±0.21, P=0.001 and also aortic sinus diameter (2.06±0.41 vs. 1.44±0.34, P=0.002 were significantly dilated, while sinutuboar junction diameter (1.65±0.5 vs. 1.28±0.29, P=0.094 was not dilated. Left ventricular function was in the normal range. Conclusions: This study showed good left ventricular function, but some abnormalities in lateral tricuspid tissue Doppler velocities. Neoaortic and pulmonary diameters were significantly dilated, while aortic and pulmonary insufficiencies were clinically insignificant in most of the patients. Long-term follow-up is necessary in these

    Due to the narrow surgical indications for hepatocellular carcinoma (HCC) in the cirrhotic liver with decreased liver function, transcatheter arterial chemoembolization (TACE) has been generally performed in the worldwide institutions for the curative or palliative treatment of this tumor. In the majority of the cases, however, the tumors are not completely necrotized, and the recurrence rate after TACE is still high even for the patients who have received curative TACE for grossly uncomplicated localized lesions. Thus, on the follow-up imaging studies after TACE, accurate diagnosis of a residual or locally recurrent tumor is crucial and this can facilitate successful management at an early stage of the disease so as to avoid more complicated or advanced disease that has an unfavorable prognosis. Multiphase dynamic CT, including the pre-contrast phase, the arterial phase and the more delayed phase imaging, is popularly used for evaluating the therapeutic effect of TACE because the degree of uptake and the distribution of the iodized oil within the tumor and the surrounding hepatic parenchyma can provide useful information on the degree of tumor necrosis, and so a strategy can be planned for the subsequent therapeutic approach. The article by Jang et al. in this issue of the Korean Journal of Radiology is one of the studies that have assessed the diagnostic ability of multiphase dynamic CT to depict a viable tumor in HCC treated with TACE. In that study, a review of the previous serial CT images provided more accurate information for the determination of the viability of the lesion than did a review of the last CT alone in several cases that were roughly verified by subsequent pathological review of the resected specimens. The overall false positive interpretation rate for the totally necrotic tumors was just 3%; however, false negative interpretation for viable tumors was 22%, which was still too high to get reliable results with using the serial follow-up CT as

    Objective: To make follow-up study and evaluation of benign stricture of upper gastrointestinal tract (UGIT) with interventional procedure. Methods: There were 85 cases of benign stricture of UGIT with interventional procedure. There were 35 cases with pneumatic dilation (group A), 25 cases with permanent (group B) placement, and 25 cases with temporary (group C) placement of expandable metallic stent, respectively. All cases were completed under fluoroscopy. 35 cases of group A had 67 times dilations (mean 1.9 times). Fifteen partial covered and 10 uncovered expandable metallic stents were permanently placed in the 25 cases of group B. 25 partial covered expandable metallic stents were temporarily placed in the 25 cases of group C, and the stents were drawn out via gastroscopy 3-7 days later. All stents placement and drawing were technically successful. The most strictured diameters of UGIT were 0.7-8.5 mm before dilations and 5.1-20.0 mm after dilations. Dysphagia scores of all cases were from grade 2 to 4 before dilations, and from grade 0 to 1 after dilations. Follow-up time of all cases was from 6 months to 36 months (mean 19.1 months). Results: Complications in group A included chest pain (n =10), reflux (n = 8), and bleeding (n = 3). Seven (20%) in 35 cases of group A had dysphagia relapse during follow-up over 6 months; 32 (91%) in 35 cases of group A had dysphagia relapse during follow-up over 12 months; 19(95%) in 20 cases of group A had dysphagia relapse during follow-up over 36 months. Complications in group B included chest pain (n = 10), reflux (n = 15), bleeding (n = 3), and stent migration (n = 4). Five (20%) in 25 cases of group B had dysphagia relapse during follow-up over 6 months; 3(25%) in 12 cases of group B had dysphagia relapse during follow-up over 12 months; 3 (60%) in 5 cases of group B had dysphagia relapse during follow-up over 36 months. Complications in group C included chest pain (n = 10), reflux (n = 3), and bleeding (n = 4). 3

    Objective: To evaluate the mid-long term effects of uterine fibroids embolization. Methods: Uterine artery embolization (UAE) was performed in 110 patients with uterine fibroids with follow up of 48-72 months. All the patients were examined with transvaginal color ultrasound. 51 cases were embolized with mixed liquor of lipiodol and pingyangmycin and another 59 cases with polyvinyl alcohol particles (350-700 μm, in diameter). The mid-long term clinical effects, complications, change of serum sexual hormone, pregnancy and delivery after UAE were observed. Results; Bilateral uterine artery embolization was performed in 110 cases with following outcomes in improvements of menorrhagia in 93/94 (98.9%) and the bulked-related symptoms in 26/26 (100%), decrease of the volumes of uterus 51.5% ± 3.1% (t value 2.861, P<0.01) and fibroids 64.2% ± 6.6% (t value 2.664, P<0.01). No statistical differences in serum levels of luteinizing, follicle stimulating hormone and estradiol before and after the uterine artery embolization were found. All events included abdominal pain in 6/110 (5.5%), fever in 90/110 (81.8%), colporrhagia in 95/110 (86.4%), haematuria in 11/110 (10.0%), non-targeted embolization of bladder in 1/110 (0.9%), transient amenorrhea in 3/110 (2.7%), permanent amenorrhea due to ovarian failure in 3/110 (2.7%), failure of embolization in 1/110 (0.9%) and recurrence after uterine fibroids embolization in 4/110 (3.6%). There were 7 times of pregnancies in 5 patients, including 4 times of deliveries in 4 patients, and one patient accepted artificial abortion 3 times, but with no fibroids recurrences or enlargement under ultrasound follow up. Conclusion: The mid-long term effects of uterine fibroids embolization are positive, stable and safe, but with a low recurrence rate slight ovarian functional change and still safe for pregnancy and delivery.

    Atherosclerosis of femoropopliteal arteries is an important cause of morbidity and mortality. Percutaneous transluminal angioplasty (PTA) has only limited success in treating these arteries, mainly because of the high rate of recurrent stenosis. Cryoplasty has been proposed as a technique which might improve treatment outcome. This study reports our single-center experience with cryoplasty. Thirty-two claudicants, 33 arteries, in whom conservative therapy failed, were consecutively included. Duplex ultrasound (US), angiography, and ankle-brachial index (ABI) measurement were performed before the procedure; ABI and duplex US, 2 weeks and 3, 6, and 12 months after the procedure. Patients' symptoms were categorized according to the Rutherford classification. Lesions were classified as TASC A, B, or C according to angiographic appearance. Differences in ABI before and after the procedure were defined as significant at p < 0.05 by paired t-test. Patency was evaluated using duplex US by determining the peak systolic velocity ratio. Sixteen TASC A lesions, 13 TASC B lesions, and 4 TASC C lesions were included. ABI improved significantly for TASC A lesions 2 weeks and 3 months postprocedure. Patency after 2 weeks, 6 months, and 12 months was 93%, 67%, and 64% for TASC A lesions, 83%, 31%, and 31% for TASC B lesions, and 100%, 50%, and 33% for TASC C lesions, respectively. In conclusion, cryoplasty has good immediate success rates and patency rates similar to the results of conventional PTA in the literature.

    The purpose of this study was to evaluate the long-term outcomes of the Ross procedure in a nationwide follow-up. This retrospective study involved all children treated with the Ross procedure in Finland between 1994 and 2009. The clinical records were reviewed for demographic and anatomical characteristics, Ross operation data, surgical history and status at the latest follow-up. The median follow-up time was 11.5 (range 2.4-19.2) years. Fifty-one patients underwent either the Ross (n = 37) or the Ross-Konno (n = 14) procedure at a median age of 4.8 (range 0.02-16.3) years, including 13 infants (Ross procedure was aortic valve stenosis, regurgitation or both, which was observed in 29, 24 and 47% of patients, respectively. The early mortality (before hospital discharge) rate was 10% (31% in infants) and the late mortality rate 6% (15% in infants). Higher mortality was discovered in patients treated with the Ross-Konno procedure (P = 0.001). The most common cause for reintervention was pulmonary homograft stenosis. The rate of freedom from right ventricular outflow tract reintervention was 98% at 5 years, 83% at 10 years and 59% at 15 years. The rate of freedom from autograft reintervention was 98% at 5 and 10 years, and 81% at 15 years. At the latest follow-up visit, mild-to-moderate aortic root dilatation was reported in 52% of patients, and 4 patients had undergone autograft-related reinterventions. Trivial autograft valve regurgitation was commonly seen, but only 1 patient developed severe autograft regurgitation requiring mechanical valve replacement 15.9 years after the Ross operation. The most common reason for reintervention after the Ross procedure in children is homograft stenosis. Aortic root dilatation and autograft valve regurgitation are relatively common but rarely lead to reinterventions before adulthood. Intraoperative complications and complex cardiac anatomy are associated with high mortality in infants undergoing the Ross-Konno procedure. In our

    A follow-up habitat evaluation procedures (HEP) analysis was conducted on the West Foster Creek (Smith acquisition) wildlife mitigation site in May 2007 to determine the number of additional habitat units to credit Bonneville Power Administration (BPA) for providing funds to enhance and maintain the project site as partial mitigation for habitat losses associated with construction of Grand Coulee Dam. The West Foster Creek 2007 follow-up HEP survey generated 2,981.96 habitat units (HU) or 1.51 HUs per acre for a 34% increase (+751.34 HUs) above baseline HU credit (the 1999 baseline HEP survey generated 2,230.62 habitat units or 1.13 HUs per acre). The 2007 follow-up HEP analysis yielded 1,380.26 sharp-tailed grouse (Tympanuchus phasianellus) habitat units, 879.40 mule deer (Odocoileus hemionus) HUs, and 722.29 western meadowlark (Sturnella neglecta) habitat units. Mule deer and sharp-tailed grouse habitat units increased by 346.42 HUs and 470.62 HUs respectively over baseline (1999) survey results due largely to cessation of livestock grazing and subsequent passive restoration. In contrast, the western meadowlark generated slightly fewer habitat units in 2007 (-67.31) than in 1999, because of increased shrub cover, which lowers habitat suitability for that species.

    The role of bariatric surgery and its role in adolescent is still under discussion worldwide. The aim of this study is to report an Italian survey for bariatric procedures in adolescents and the outcome with a medium and long-term follow-up. We retrospectively analyzed consecutive data added into the Italian register of the society for bariatric surgery(period 2000-2010). We evaluated all patients treated in a 10-year period with a mean follow-up of 3 years. Inclusion and exclusion criteria were created. All patients were aged between 13 and 18 years. We evaluated and compared clinical data. After reviewing medical charts, 173 patients were considered for the study; 85 patients were treated with adjustable gastric band (AGB), 47 with intragastric balloon (IB), 26 with sleeve gastrectomy (SG) and other 15 patients with malabsorptive techniques (MT). Among clinical data, there was a statistical difference in terms of %excess weight loss (%EWL) between techniques only after 1 year post-procedure; at 5 years, considering the percentage of patients studied, sleeve gastrectomy had the best %EWL respect to other non malabsorptive techniques (padolescent; more than 80% of patients are followed until 5 years post-op but only few patients (less than 5%) until 10 years. Our results demonstrated that sleeve gastrectomy in adolescent is safe and had a better %EWL respect to other non-malabsorptive bariatric procedures. level III. Copyright © 2017 Elsevier Inc.

    The purpose of this study is to compare the usefulness of ultrasonography in follow up evaluation after the Ilizarov procedure with that of plain radiography. We analyzed ultrasound findings in twelve patients who had undergone the Ilizarov procedure, and retrospectively compared the results with the findings of plain radiography. The procedure was performed due to post-traumatic limb deformity or non-union (nine of twelve patients), congenital pseudoarthrosis (one case), sequelae of poliomyelitis (one case), and short stature (one case). The patients` mean age was 29 years; eleven of twelve were male. Ten of twelve procedures were performed on the tibia and two on the femur. After 7-10 days, distraction was initiated at a rate of 0.25 mm four times a day. Ultrasonography was performed with a 5-10 MHz linear or convex transducer; new bone formation was defined as dotted or linear echogenic foci within a hypoechoic distraction gap. Initial ultrasonographic examination was performed 2-4 weeks after distraction, and the results were compared with those of plain radiography. Color doppler imaging was performed in three cases. After the Ilizarov bone lengthening procedure, ultrasound appears to be useful for follow-up examination. New bone formation, as well as complications, can be detected earlier; it can indicate whether ultrasound-guided interventional procedure is required, and if combined with color doppler study, is able to detect the periosteal blood supply. Further evaluation of the clinical significance of preserved periosteal blood supply seems however, to be needed. (author). 18 refs., 4 figs.

    The purpose of this prospective study was to evaluate whether stent placement in infrapopliteal arteries is helpful in failed percutaneous transluminal angioplasty (PTA). Infrapopliteal PTA was performed in 70 arteries of 66 patients with chronic critical lower limb ischemia. The group comprised 55 males and 11 females, with an average age of 63.4 (range, 42-82) years. Diabetes mellitus was present in 92.4% of patients. Only the palpable anterior tibial and posterior tibial arteries were evaluated. Stents (Xpert stent; Abbot Vascular, Redwood City, CA, USA) were placed in 16 arteries where PTA was not successful (the failure was defined as residual stenosis >30% after PTA). In 54 arteries simple PTA was performed and was technically successful. Twenty-four nondilated arteries with no significant stenosis served as a comparison group. The 12-month patency rate was evaluated according to a combination of palpation and Doppler ultrasound. In all cases stent placement restored the flow in the artery immediately after unsuccessful PTA. Twelve-month follow-up showed a patency rate of 82% in the PTA group, 78% in the stent group, and 69% in the comparison group. We conclude that stent placement in the case of unsuccessful infrapopliteal PTA changed technical failure to success and restored flow in the dilated artery. At 12-month follow-up the patency rate of infrapopliteal arteries stented for PTA failure did not differ significantly either from nonstented arteries with an optimal PTA result or from a comparison group of nonintervened arteries.

    Antegrade continence enema (ACE) has become an important therapeutic modality in the treatment of intractable constipation and fecal incontinence. There are little data available on the long-term performance of the ACE procedure in children. A retrospective review of patients who underwent the ACE procedure was conducted. Irrigation characteristics and complications were noted. Outcome was assessed for individual encounters based on frequency of bowel movements, incontinence, pain, and predictability. One hundred seventeen patients underwent an ACE. One hundred five patients had at least 6 months of follow-up, and were included in the analysis. Diagnoses included myelodysplasia (39%), functional intractable constipation (26%), anorectal malformations (21%), nonrelaxing internal anal sphincter (7%), cerebral palsy (3%), and other diagnoses (4%). The average follow-up was 68 months (range 7-178 months). At the last follow-up, 69% of patients had successful bowel management. Of the 31% of patients who did not have successful bowel management, 20% were using the ACE despite suboptimal results, 10% required surgical removal, and 2% were not using the ACE because of behavioral opposition to it. Patients were started on normal saline, but were switched to GoLYTELY (PEG-3350 and electrolyte solution) if there was an inadequate response (61% at final encounter). Additives were needed in 34% of patients. The average irrigation dose was 23 ± 0.7 mL/kg. The average toilet sitting time was 51.7 ± 3.5 minutes, with infusions running for 12.1 ± 1.2 minutes. Stomal complications occurred in 63% (infection, leakage, and stenosis) of patients, 33% required surgical revision and 6% eventually required diverting ostomies. Long-term use of the ACE gives successful results in 69% of patients, whereas 63% had a stoma-related complication and 33% required surgical revision of the stoma.

    The authors analyzed 30 patients whose celiac artery or its branches were dissected during the procedure of transcatheter arterial embolization (TAE) for hepatocellular carcinoma (HCC) and were followed up angiographically. The incidence of arterial dissection was 1.25%. The dissection occurred most frequently in the celiac artery (40% 12/30) and the proper hepatic artery (28% 7/30). The frequency of arterial dissection was affected by the status of the vessel and the experience of the operator. The follow-up angiography revealed complete recanalization in 40% (12/30), irregularity and narrowing of the lumen in 23% (7/30), pseudoaneurysm formation in 23% (7/30), and complete obstruction in 13% (4/30) of the cases. The rate of recanalization in the celiac artery was lower than that of any other arteries in our series. Recanalization to a certain degree without therapeutic intervention was observed in 72% of the dissected arteries enabling and contributing to subsequent successful TAE within 2 months in 78% of the patients with the dissection

    Two-staged hybrid coronary revascularization (HCR) is a novel procedure in selected patients with multivessel coronary artery disease. However, few studies are available on the mid-term or long-term outcomes of this 2-staged procedure as compared to off-pump coronary artery bypass (OPCAB). To compare in-hospital and mid-term follow-up outcomes of 2-staged HCR with OPCAB in patients with multivessel coronary artery disease. The present retrospective study analyzed the data from 73 patients who underwent the 2-staged HCR (HCR group) during 2012-2014 at the heart center. Three hundred and eighty-three patients who underwent conventional OPCAB by the same surgeon were selected for the comparative analysis performed on in-hospital and mid-term follow-up outcomes between the two groups. No significant difference was observed in the preoperative outcome between the two groups. The HCR group had a shorter operation duration (152.9 ±43.8 vs. 262.6 ±51.8 min, p < 0.05), less bleeding (558.6 ±441.3 vs. 1035.5 ±613.3 ml, p < 0.05), shorter mechanical ventilation (9.4 ±7.4 vs. 19.0 ±18.3 h, p < 0.05), and less blood transfusion (12 (16.4%) vs. 200 (52.2%), p < 0.05). The mean follow-up duration was 25.0 ±9.6 months in the HCR group and 22.8 ±10.6 months in the OPCAB group. The incidence of major adverse cardiac or cerebrovascular events (MACCE) was similar in both groups (4 (5.5%) vs. 10 (2.8%), p = 0.408). The estimated 3-year survival was similar in both groups (log-rank χ 2 = 1.041, p = 0.308). The 2-staged HCR is a safe and effective surgical procedure and may offer similar mid-term follow-up outcomes to OPCAB.

    The rate of pacemaker implantation is rising. Given that the life expectancy of the population is projected to increase, a large number of elderly patients are likely to be implanted in the future. As pacemaker batteries can last for 8-10years, an increasing number of pacemaker recipients will require replacement of their devices when they become nonagenarians. To analyse the short- and long-term outcomes after device replacement in nonagenarians. Patients aged≥90years referred to a tertiary centre for pacemaker replacement from January 2004 to July 2014 were included retrospectively. Clinical follow-up data were obtained from clinical visits or telephone interviews with patients or their families. The primary clinical endpoint was total mortality. Secondary endpoints included early and delayed procedure-related complications and predictive risk factors for total mortality. Sixty-two patients were included (mean age 93.3±2.9years at time of pacemaker replacement). Mean procedure duration was 35.7±17.2minutes. Mean hospital stay was 2.2±1.1days. One patient died from a perioperative complication. Thirty-seven patients (59.7%) died during a median follow-up of 22.1months (interquartile range, 11.8-39.8months). Survival rates were 84.2% (95% confidence interval [CI] 71.8-91.5%) at 1year, 66.9% (95% CI 51.8-78.2%) at 2years and 22.7% (95% CI 10.6-37.7%) at 5years. Atrial fibrillation (hazard ratio 2.47, 95% CI 1.1-5.6) and non-physiological pacing (i.e. VVI pacing in patients in sinus rhythm) (hazard ratio 2.20, 95% CI 1.0-4.9) were predictors of mortality. Pacemaker replacement in nonagenarians is a safe and straightforward procedure. These data suggest that procedures can be performed securely in this old and frail population, with patients living for a median of 30months afterwards. Copyright © 2015 Elsevier Masson SAS.

    The author has studied the clinical results of CT and MR findings of proximal carotid artery occlusion using detachable balloons in the treatement of unclippable internal carotid (IC) aneurysms. From 1987 to 1995, twenty-eight patients with IC aneurysms were treated by proximal artery occlusion with detachable balloons. Of these patients, 4 had aneurysms arising from the supraclinoid portion of the IC artery, 23 had aneuryms arising from cavernous portion of the IC artery, and one had aneurysm arising from cervical portion of the IC artery. Of the 28 patients, 7 patients without CT or MR examinations were excluded in this study. The mean follow-up period was 18.6 months. The causes of aneurysm formation were spontaneous in 17 cases and traumatic in 4 cases. Of 20 patients with aneurysms arising from supraclinoid and cavernous portion of the IC artery, 16 patients (80%) had cranial nerve symptoms by mass effect. Five patients had epistaxis (3 patient), carotid cavernous fistula (1 patient) or subarachnoid hemorrhage (1 patient) due to aneurysm rupture. Two patients, each with aneuryms arising from supraclinoid and cervical portion of carotid artery had 9th and 12th cranial nerve symptom. There were three instances of complication after permanent occlusion; two patients had subarachnoid and intracerebral hemorrhage by aneurysm rupture and expired. One patient had ischemia of posterior cerebral artery teritorry after one day. Delayed ischemic event did not occur during the follow-up period. All aneurysms of the carotid artery below the level of ophthalmic artery presented radiographic proof of complete thrombosis within two months. However, complete thrombosis of aneurysm was considerably delayed in two aneurysms arising from the supraclinoid portion of the carotid artery. In long-term follow-up study, completely thrombosed aneurysms decreased in size slowly. But incompletely thrombosed aneurysms did not decrease in size for a long time and began to contract after

    Full Text Available We report a rare case of cystic adventitial disease of popliteal artery with venous aneurysm of popliteal vein. A 46-year-old woman had sudden-onset intermittent claudication and coldness in her right leg. The right-sided ankle-brachial pressure index (ABI was 1.01, but peripheral arterial pulsation was decreased at knee venting position. Computed tomography revealed simple cystic lesion of the popliteal artery and stenosis of the arterial lumen in this lesion. The patient was treated by complete resection of the cystic adventitial layer of popliteal artery. A venous aneurysm of popliteal vein was revealed by intraoperative echo and was simply ligated. The patient had uneventful postoperative course and no symptoms of relevance during the two years of follow-up.

    We describe a novel approach for the endovascular treatment of femoral artery occlusion as a result of Angio-Seal closure device deployment. Angio-Seal is the most commonly used vascular closure device following percutaneous coronary and peripheral catheterizations worldwide. A rare complication of Angio-Seal deployment is an occlusion of the femoral artery leading to limb ischemia requiring revascularization. Given its unique ability to cut both atherosclerotic plaque and the Angio-Seal anchor with a collagen plug at operator-directed planes, TurboHawk/HawkOne atherectomy device can be a fast and effective approach to treat Angio-Seal-associated femoral artery occlusions. We studied 13 consecutive patients who developed Angio-Seal-associated femoral artery occlusions that occurred from 3 hours to several weeks after catheterization. These patients were successfully treated with TurboHawk/HawkOne directional atherectomy followed by balloon angioplasty with no complications. During a mean follow-up period of 20.4 ± 17.3 months, 12 patients remained claudication free with no evidence of obstructive arterial disease of the treated segment on imaging studies. One patient developed restenosis that was treated with repeat atherectomy and balloon angioplasty following which he was asymptomatic at follow-up. The use of directional atherectomy followed by balloon angioplasty is a quick, safe, and effective endovascular approach to treating Angio-Seal-associated femoral artery occlusions. It is associated with an excellent success rate, no complications, and good midterm outcomes.

    Our objective was to evaluate the complications and early follow-up of the tension-free vaginal tape (TVT)-SECUR, a new minimally invasive anti-incontinence operative procedure. A prospective, observational, and consecutive patient series was conducted. Perioperative and 12-month postoperative data were prospectively collected for the first 50 patients against the next consecutive 50 patients, among which TVT-SECUR specific surgical measurements were adopted (Canadian Task Force classification 2). In private hospital operative theatres, the TVT-SECUR operation was performed. Patients with urodynamically proved stress urinary incontinence were enrolled in this study after detailed informed consent was given. The TVT-SECUR, in the hammock shape to mimic the TVT-obturator placement, yet with no skin incisions, required neither bladder catheterization nor intraoperative diagnostic cystoscopy. The clinical and surgical data of 100 consecutive patients with TVT-SECUR were collected prospectively. Two patients had urinary obstructions and needed surgical tape-tension relief. One patient had a 50 mL paravesical self-remitting hematoma. At the first-month postoperative follow-up appointment, the objective therapeutic failure rate for the TVT-SECUR procedure among the 50 patients was 20.0% (10 patients). But when the tape was placed close to the urethra with no space allowed in between, the failure rate in the second patient group went down to 8.0% (4 patients); yet no further postoperative bladder outlet obstruction was diagnosed. Four (8.0%) patients in the first group had vaginal wall penetration with the inserters, requiring withdrawal, reinsertion, and vaginal wall repair. This was avoided with the second patient group by facilitating the inserters' introduction by widening the submucosal tunnel to 12 mm. Six (12.0%) other patients in the first group needed postoperative trimming of a vaginally extruded tape segment, performed in the office with satisfactory results

    Purpose: the purpose of this prospective study was to determine the restenosis grade, the intima hyperplasia and the stent expansion via angiographic follow-up six months after carotid artery stenting. Materials and methods: in 100 patients, angiographic follow-up was performed 5.9 months (range: 2.9 - 11.4 months) after carotid artery stenting. The restenosis grade, the intima hyperplasia and the stent expansion were measured by selective angiography of the treated carotid artery. Results: the mean restenosis grade was 16% (range: 0 - 78%). In 6 of 100 patients (6%), a restenosis grade of > 50% was measured. In 4 patients the restenosis grade was 50 - 70%. In 2 patients the restenosis grade was > 70%. In 91 of 100 patients (91%), the restenosis was localized in the former area of stenosis of the carotid artery, and in 9 of 100 patients (9%), the restenosis was localized in the cranial stent end. The mean grade of intima hyperplasia was 31% (range: 2 - 70%). The mean increase in stent expansion at the time of follow-up was 10% (range: 0 - 59%). No correlation was able to be determined between the grade of stenosis and the grade of restenosis (rho = 0,017, range: -0.180 - 0.213), between the grade of residual stenosis and the grade of restenosis (rho = 0,257, range: 0.064 - 0.431) and between intima hyperplasia and the grade of restenosis (rho = 0,476, range: 0.309 - 0.615). Conclusions: carotid artery stenting is associated with a low incidence of high-grade restenosis 6 months after an intervention. The intima hyperplasia, which can be observed in each Wallstent, is partly compensated by the expansion of the self-expandable stent. Without a correlation between the grade of residual stenosis and the grade of restenosis, low-grade residual stenosis can be accepted. Therefore, we recommend undersized postdilation of the Wallstent. (orig.)

    Background: There is a potential risk of aneurysm rupture after parent artery revascularization because of increased blood flow. The purpose of this study is to assess the efficacy and safety of Wingspan stent-assisted coil embolization in the treatment of intracranial aneurysms with symptomatic parent artery stenosis. Methods: Thirty-five consecutive patients (19 men, 16 women; age range, 48–79 years; mean age, 60.4 years) harboring 35 unruptured wide-necked or fusiform intracranial aneurysms (mean size 6.8 mm; range 2.5–18 mm.) with symptomatic parent artery stenosis (mean degree 71.1%; range 50–92%) were treated with the Wingspan stent-assisted coiling. Twenty-four lesions were located in the anterior circulation and eleven in the posterior circulation. Patients were premedicated with antiplatelet therapy consisting of aspirin 300 mg and clopidogrel 75 mg for at least 3 days before the procedure. Following pre-dilatation and stent placement, a coiling microcatheter entered the aneurysm through the interstices of the stent, and then coiling was performed. After the procedure, clopidogrel 75 mg daily was recommended for an additional 30 days, and aspirin 100 mg was recommended throughout follow-up. For all patients, clinical follow-up was conducted by clinic visitation, or telephone interview. Angiographic follow-up with DSA was recommended at 6 months and 1 year after the procedure. Angiography follow-up (mean time 10.6 months) was obtained in 31 cases (88.6%). The technical feasibility of the procedure, procedure-related complications, angiographic results, clinical outcome and follow-up angiography were evaluated. Results: In every case, technical success was achieved. The degree of stenosis was reduced from 71.1% to 17.4% after balloon angioplasty and stenting. Immediate angiography demonstrated complete occlusion in 25 cases (71.4%), neck remnant in 7 cases (20.0%), and incomplete occlusion in 3 cases (8.6%). Procedure-related morbidity occurred in two

    Full Text Available BACKGROUND: We prospectively and longitudinally determined the effects of childhood obesity on arterial stiffening and vascular wall changes. Changes in arterial stiffness measured as pulse wave velocity (PWV and vascular morphology of the radial (RA and dorsal pedal arteries (DPA were examined in obese adolescents compared to lean subjects in a 5-year follow-up study. METHODOLOGY/PRINCIPAL FINDINGS: A total of 28 obese subjects and 14 lean controls participated in both baseline (14 years old and follow-up studies. PWV was measured by tonometer (SphygmoCor® and recorded at RA and carotid artery, respectively. Intima thickness (IT, intima-media thickness (IMT and RA and DPA diameters were measured using high-resolution ultrasound (Vevo 770™. Over the course of 5 years, PWV increased by 25% in the obese subjects as compared to 3% in the controls (p = 0.01. Diastolic blood pressure (DBP increased by 23% in the obese subjects as opposed to 6% in controls (p = 0.009. BMI increased similarly in both groups, as did the IT and IMT. The change in PWV was strongly associated to the baseline BMI z -score (r = 0.51, p<0.001, as was the change in DBP (r = 0.50, p = 0.001. CONCLUSIONS/SIGNIFICANCE: During the transition from early to late adolescence, there was a general increase in arterial stiffness, which was aggravated by childhood obesity. The increase in arterial stiffness and DBP after 5 years was closely correlated to the baseline BMI z -score, indicating that childhood obesity has an adverse impact on vascular adaptation.

    In this 8 years' follow-up study, we evaluated the long-term outcomes of the addition of clopidogrel to aspirin during the first year after coronary artery bypass grafting, versus aspirin plus placebo, with respect to survival, major adverse cardiac, or major cerebrovascular events, including revascularization, functional status, graft patency, and native coronary artery disease progression. In the initial Clopidogrel After Surgery for Coronary Artery Disease trial, 113 patients were randomized to receive either daily clopidogrel (n = 56) or placebo (n = 57), in addition to aspirin, in a double-blind fashion for 1 year after coronary artery bypass grafting. All patients were re-evaluated to collect long-term clinical data. Surviving patients with a glomerular filtration rate > 30 mL/min were asked to undergo a coronary computed tomography angiogram to evaluate the late saphenous vein graft patency and native coronary artery disease progression. At a median follow-up of 7.6 years, survival rate was 85.5% ± 3.8% (P = .23 between the 2 groups). A trend toward enhanced freedom from all-cause death or major adverse cardiac or cerebrovascular events, including revascularization, was observed in the aspirin-clopidogrel group (P = .11). No difference in functional status or freedom from angina was observed between the 2 groups (P > .57). The long-term patency of saphenous vein graft was 89.11% in the aspirin-clopidogrel group versus 91.23% in the aspirin-placebo group (P = .79). A lower incidence of moderate to severe native disease progression was observed in the aspirin-clopidogrel group versus the aspirin-placebo group (7 out of 122 vs 13 out of 78 coronary segments that showed progression, respectively [odds ratio, 0.3 ± 0.2; 95% confidence interval, 0.1-0.8; P = .02]). At 8 years' follow-up, the addition of clopidogrel to aspirin during the first year after coronary artery bypass grafting exhibited a lower incidence of moderate to severe

    Objective: To investigate prospectively the apparent diffusion coefficient (ADC)in evaluating the capability of diffusion-weighted imaging (DWI) technique for detecting viable tumor tissue after transarterial chemoembolization (TACE) of liver cancer. Methods: Institutional review board approval was obtained, and all patients were provided with informed consent. DWI, enhanced CT and DSA examinations were performed in 16 patients with liver cancer after TACE. Qualitative evaluations of the capability for detecting the remaining or recurrent viable tumor with DWI were performed by comparing enhanced-CT and DSA. ADCs and maximum CT enhancement value(HU) were measured(in 14 of the 16 patients)for lesions after TACE. And their relationships were investigated by comprehension correlative analysis. Results: Liver cancer after TACE presented variable signal intensities on DWI. The homogeneous accumulation of iodized oil observed on CT in 2 of 16 patients with liver cancer after TACE showed no tumor stain observed on DSA but with corresponding homogeneous hypointensity on DWI. The partial defects shown in accumulation of iodized oil in 2 of 16 patients represented the tumor stain on DSA corresponding to hyperintensities on DWI. None or faint accumulation of iodized oil areas in 12 of all patients, showed striking tumor stains corresponding to hyperintensities on DWI, and tumor necrosis had none or sight tumor stain on DSA, corresponding to hypointensities on DWI. A correlation between ADCs and maximum CT enhancement value (HU) of lesions after TACE was found (r=-0.76490, <0.05). Conclusion: Diffusion MRI is an useful method for detecting tumor remnant or recurrence of liver cancer after TACE, and can be used for the follow-up. (authors)

    The purpose of this study was to evaluate the feasibility, safety and midterm outcome of elective implantation of the Carotid Wallstent (registered) in patients considered to be at high surgical risk. In a prospective study, 54 carotid artery stenoses in 51 patients were stented over a 24-month period. Three patients underwent bilateral carotid artery stenting. Institutional inclusion criteria for invasive treatment of carotid occlusive disease (carotid endarterectomy or carotid artery stenting) are patients presenting with a 70% or more symptomatic stenosis and those with an 80% or more asymptomatic stenosis having a life-expectancy of more than 1 year. All patients treated by carotid artery stenting were considered at high risk for carotid endarterectomy because of a hostile neck (17 patients-31.5%) or because of severe comorbidities (37 patients-68.5%). No cerebral protection device was used. Of the 54 lesions, 33 (61.1%) were symptomatic and 21 (38.8%) were asymptomatic. Follow-up was performed by physical examination and by duplex ultrasonography at 1 month, 6 months, 1 year and 2 years after the procedure. All 54 lesions could be stented successfully without periprocedural stroke. Advert events during follow-up (mean 13.9 ± 5.7 months) were non-stroke-related death in 6 patients (11.1%), minor stroke in 4 stented hemispheres(7.4%), transient ipsilateral facial pain in 1 patient (1.8%),infection of the stented surgical patch in 1 patient (1.8%) and asymptomatic in stent restenosis in 4 patients (7.4%). The percutaneous implantation of the Carotid Wallstent (registered) , even without cerebral protection device, appears to be a safe procedure with acceptable clinical and ultrasonographic follow-up results in patients at high surgical risk. But some late adverse events such as ipsilateral recurrence of non-disabling (minor) stroke or in stent restenosis still remain real challenging problems

    Transcatheter closure of patent ductus arteriosus (PDA) is a well established procedure and an accepted treatment modality for small to moderate-sized PDA. This study aimed to evaluate the immediate and follow-up results of transcatheter closure of large PDAs with severe pulmonary arterial hypertension (PAH) in adults. After a complete hemodynamic evaluation differentiating from the reversibility of severe PAH, transcatheter closure of PDA was performed. Patients were followed up clinically and echocardiographically at 24 hours, 1 month, 3 months, 6 months, 12 months and 24 months after occlusion. Twenty-nine patients had successful occlusion, pulmonary artery pressure (PAP), left ventricular ejection fraction (LVEF) and fractional shortening (FS) significantly decreased immediately after occlusion ((106 ± 25) mmHg vs. (50 ± 14) mmHg, P closure, the signs and symptoms improved markedly in all 29 patients, and PDAs were completely closed and remained closed during the follow-up. Eighteen patients having different degrees of dyspnea were treated with angiotensin converting enzyme inhibitor (ACEI) and/or digoxin after occlusion. Nine patients whose pulmonary vascular resistence (PVR) > 6 Wood units accepted targeted PAH therapy. After 1 to 3 months of peroral drug therapy, their exercise tolerance improved from New York Heart Association (NYHA) class III-IV to NYHA class I. During follow-up, no latent arrhythmias were found, the left atrial diameter (LAD), left ventricular end-diastolic diameter (LVEDD), left ventricular end-systolic diameter (LVESD), left ventricular mass index (LVMI) and pulmonary artery systolic pressure (PASP) decreased significantly (P closure of large PDA with severe PAH is feasible, effective, and safe in adults. Significant left ventricular systolic changes may occur after closure of large PDA, and left ventricular function usually recovers within a few months.

    Full Text Available Introduction. Nebivolol, a third-generation beta-blocker (BB shows a highly selective beta-blockade and specific vasodilating effects due to getting free nitro-oxide from the dysfunctional endothelium. Objective. The aim of the study was to investigate the antihypertensive effect of nebivolol in patients with arterial hypertension (AH of both sexes. Methods. Systolic and diastolic blood pressure (BP, heart rate and serum glycemia, creatinin, cholesterol and trygliceride were measured after a 6-week treatment with a single 5 mg dose of nebivolol once daily so as to assess its efficacy and metabolic effects, as well as its tolerance by using a questionnaire answered by physicians and patients. Results. Out of 520 patients with mild or moderate AH, 430 (82.7% were treated with nebivolol as monotherapy. After a 6-week treatment with nebivolol, with very good tolerability and neutral metabolic effects, systolic BP was significantly decreased (in male from initial 165±19 to 129±12 mm Hg, and female from initial 169±22 to 132±15 mm Hg at the end of the study; average decrease 22.3%, p<0.001 and as well as diastolic BP (male from initial 103±12 to 79±6 mm Hg and female from initial 100±9 to 82±7 mm Hg, average decrease 22.6%; p<0.001. Conclusion. After a 6-week treatment nebivolol significantly decreased systolic and diastolic BP in patients with mild and moderate AH, independently of the sex.

    Hysteroscopic flexible micro-insert (Essure) is an ambulatory improvement of fallopian tube sterilization, which is a deliberated suppression of fertility. The aim of this study was an evaluation of feasibility (learning curve) and the first year outcome of this method. This prospective study, carried out between February 2002 and March 2003, included patients who were matching with manufacturer recommendations. One surgeon only realized all the device placements. Fifty patients were included (one year follow-up). Mean age was 41 (+/-3.3), mean parity was 2.7 (+/-0.8). Mean time needed for device placement was 26 minutes (+/-6.5) and was reduced with increased experience. Six failures of placement (12%) were related, because of submucus leiomyomas, proximal tubal stenotic disease or too retroverted uterus. Only 5 patients (11,4%) described intensive pelvic pain during the placement. The only case of device expulsion benefited from a successful second placement. The one-year follow-up showed no significant difference of body weight increasing, duration or quantity of menstruation, neither significant pelvic pain nor vaginal bleeding. Tolerance was rated at least at "somewhat satisfied". There have been no pregnancies reported in 670 woman-months of effectiveness. Our results agree in any point with those of larger studies. We think that hysteroscopy micro-insert placement is not only reserved to specialized centers but also to any gynecologist who is used to performing hysteroscopy because of its feasibility.

    Purpose: To assess in vivo 1) MR-guided percutaneous transluminal renal angioplasty (PTRA) in experimental bilateral rabbit renal artery stenosis (RAS); 2) postprocedural follow-up by gadolinium-enhanced MR angiography versus histomorphometry.Methods: Fifteen male NZW rabbits of mean weight 4.0 kg (range 3.5-4.2 kg) underwent bilateral RAS induction by combined overdilation-deendothelialization with a gadolinium-filled balloon, passively MR-guided by the artifact of a 0.014-inch guidewire. After 4 weeks the rabbits were randomized into two groups: group A (n = 8) underwent right-sided PTRA for treatment of RAS, group B (n = 7) underwent left-sided PTRA. After another 4 weeks the rabbits were killed to assess by histomorphometry recurrent stenosis and contralateral induction injury stenosis lesions. Each step was preceded by gadolinium-enhanced three-dimensional MR angiography, and the cortex-to-aorta (C/A) signal intensity ratio was calculated.Results: RAS induction was successful in all cases. Fourteen arteries developed restenosis and 13 only initial stenosis. MR-guided PTRAs were feasible in 22 arteries (73%). For a successful catheterization of the ostium (20 arteries, 66% success rate), 10-25 steps were required. Five to eight steps were required for balloon localization and inflation for each PTRA. The restenosis effect was reflected by a 16% (12%-27%) decrease in C/A values on MR angiograms (p < 0.05).Conclusion: MR guidance and MR angiography represent a feasible, less invasive alternative for performing and assessing experimental PTRA in RAS

    Full Text Available Abstract Backround The transobturator tape procedure (TOT is an effective surgical treatment of female stress urinary incontinence. However data concerning safety are rare, follow-up is often less than two years, and complications are probably underreported. The aim of this study was to describe early and late complications associated with TOT procedures and identify risk factors for erosions. Methods It was a 27 months follow-up of a cohort of 233 women who underwent TOT with three different types of slings (Aris®, Obtape®, TVT-O®. Follow-up information was available for 225 (96.6% women. Results There were few per operative complications. Forty-eight women (21.3% reported late complications including de novo or worsening of preexisting urgencies (10.2%, perineal pain (2.2%, de novo dyspareunia (9%, and vaginal erosion (7.6%. The risk of erosion significantly differed between the three types of slings and was 4%, 17% and 0% for Aris®, Obtape® and TVT-O® respectively (P = 0.001. The overall proportion of women satisfied by the procedure was 72.1%. The percentage of women satisfied was significantly lower in women who experienced erosion (29.4% compared to women who did not (78.4% (RR 0.14, 95% CI 0.05-0.38, P Conclusion Late post operative complications are relatively frequent after TOT and can impair patient's satisfaction. Women should be informed of these potential complications preoperatively and require careful follow-up after the procedure. Choice of the safest sling material is crucial as it is a risk factor for erosion.

    The five year patency rate for femoropopliteal vein bypass grafts is around 70% according to the literature. Patency rates for synthetic grafts (eg PTFE, Dacron) range between 43 and 57%. If a vein is not available there is a new polyurethane 6 mm artery substitute on the market, that has shown in vitro promising physical characteristics and good long term results after implantation in dogs. In a prospective, randomized trial the results of the new polyurethane graft (PUR) were compared with those of a Dacron graft of the same diameter. Included in the study were 20 patients with lower limb ischemia stage Fontaine II B, III and IV, 10 in each group. Patency rates, handling of the graft and complications were analysed. During the one year follow up 7 PUR grafts had to be changed due to recurrent bypass occlusion within the first 3 months. At the end of the year there were only one PUR-bypass but 8 Dacron grafts open. 5 PUR grafts were examined histologically and no morphological reason for the occlusion, especially no myointimal hyperplasia, was found. A special regard was brought to the arterial run-off in both groups. It was confirmed to be comparable with only slightly better data for the PUR group. The exact reasons for the astonishing bad results of the PUR graft for femoropopliteal above knee bypass cannot be explained in our study. Due to the unexpected high occlusion rate the study was stopped earlier then planned.

    The Ross procedure is used in the treatment of selected patients with aortic valve disease. Pulmonary graft stenosis can appear in the long-term follow-up after the Ross intervention, but the factors involved and its clinical implications are not fully known. To describe the incidence, clinical impact and predictors of homograft stenosis and reintervention after the Ross procedure in a prospective series in a tertiary referral hospital. From 1997 to 2009, 107 patients underwent the Ross procedure (mean age: 30±11 years; 69% men; 21 aged36mmHg) and surgical or percutaneous homograft reintervention. After 15 years of follow-up (median: 11 years), echocardiographic and clinical data were available in 91 (85%) and 104 (98%) patients, respectively: 26/91 (29%) patients developed homograft stenosis; 10/104 (10%) patients underwent 13 homograft reintervention procedures (three patients underwent surgical replacement, three received a percutaneous pulmonary valve and one needed stent implantation). The other three patients underwent two consecutive procedures in follow-up; one died because of a procedure-related myocardial infarction. Rates of survival free from homograft stenosis and reintervention at 1, 5 and 10 years were 96%, 82% and 75% and 99%, 94% and 91%, respectively. Paediatric patients had worse survival free from homograft stenosis (hazard ratio [HR] 3.50, 95% confidence interval [CI]: 1.56-7.90; P=0.002), although there were no significant differences regarding reintervention (HR: 2.01, 95% CI: 0.52-7.78; P=0.31). Younger age of homograft donor was also a stenosis predictor (HR: 0.97, 95% CI: 0.94-0.99; P=0.046). The probabilities of homograft stenosis and reintervention 10 years after the Ross procedure were 29% and 10%, respectively; only one patient had a reintervention-related death. Younger donor and recipient age were associated with a higher rate of stenosis. Copyright © 2016 Elsevier Masson SAS. All rights reserved.

    Full Text Available Aim. The aim of this study was to assess the success and the survival rate of dental implants placed in augmented bone after sinus lifting procedures. Material and Methods. 31 patients were mainly enrolled for a residual upper jaw crest thickness of 3 mm. CBCT scans were performed before and after the augmentation technique and at the follow-up appointments, at 3, 6, 12, 24, and up to 60 months. The follow-up examination included cumulative survival rate of implants, peri-implant marginal bone loss, and the height of sinus floor augmentation. Results. This retrospective study on 31 patients and 45 implants later inserted in a less than 3 mm crest showed excellent survival rates (99.5%, one implant was lost before loading due to an acute infection after 24 days, and two implants did not osteointegrate and were removed after 3 months. The radiological evaluation showed an average bone loss of 0.25 mm (±0.78 mm at the first follow-up appointment (3 months up to 0.30 mm (±1.28 mm after 60-month follow-up. Conclusion. In this study it was reported how even in less than 3 mm thick crest a transcrestal technique can predictably be used with a long-term clinical and radiological outcome, giving patients excellent stability of the grafted material and healthy clinical results.

    Computed tomography with contrast injection was carried out in 18 patients who had undergone a Warren procedure for portal hypertension due to cirrhosis of the liver more than five years previously. The results show that it is not possible to drain only a part of the venous portal territory. The portal circulation does not consist of two portions, with different pressure relationships. Pressure difference across the splenorenal anastomosis is greater than that into the mediastinal veins. Postoperative development of a hepatofugal circulation continues for a long period and is not confined to the early phase only. This phenomenon is, however, not uniform. In particular, there are variations in the extent of the collateral circulation and in the maintenance of liver blood flow.

    Full Text Available Introduction: Although surgical endarterectomy remains the treatment of choice for carotid artery stenosis, stenting plays an important role as an alternative treatment modality, especially in high-risk patients. The actual safety profile associated with stenting procedures is probably better than that reported by randomized controlled trials. Aim : To assess the safety of stent implantations in extracranial arteries supplying the brain, and also to identify risk factors associated with this procedure. Material and methods: This was a post hoc analysis, with 30-day follow-up. We analyzed the results of treatment of 372 patients who underwent 408 procedures, 197 such procedures in asymptomatic, and 211 in symptomatic individuals. Stenting procedures were performed using a technique and armamentarium which were tailored to the type and anatomy of lesions. Results : There were 6 (1.5% strokes, including 2 (0.5% major strokes, 1 ipsi- and 1 contralateral, and 4 (1.0% minor strokes. In asymptomatic patients there was 1 (0.3% minor stroke. Transient ischemic attacks occurred in 5 (1.2% patients. There were 2 (0.5% non-STEMI myocardial infarctions and 2 (0.5% non-stroke related fatalities. Risk factors of these adverse events were diabetes mellitus, lesions localized in a tortuous segment of the artery, embolic material in the filter and bilateral stenoses of carotid arteries. Additional risk factors in asymptomatic patients were renal impairment and advanced coronary artery disease; and in symptomatic patients, grade 3 arterial hypertension, dislipidemia, cigarette smoking and lesions requiring predilatation. Conclusions : Stenting procedures of extracranial arteries supplying the brain, which are tailored to the type and anatomy of lesions, seem to be relatively safe.

    In the Fractional Flow Reserve Versus Angiography for Multivessel Evaluation (FAME) study, fractional flow reserve (FFR)-guided percutaneous coronary intervention (PCI) improved outcome compared with angiography-guided PCI for up to 2 years of follow-up. The aim in this study was to investigate whether the favourable clinical outcome with the FFR-guided PCI in the FAME study persisted over a 5-year follow-up. The FAME study was a multicentre trial done in Belgium, Denmark, Germany, the Netherlands, Sweden, the UK, and the USA. Patients (aged ≥ 18 years) with multivessel coronary artery disease were randomly assigned to undergo angiography-guided PCI or FFR-guided PCI. Before randomisation, stenoses requiring PCI were identified on the angiogram. Patients allocated to angiography-guided PCI had revascularisation of all identified stenoses. Patients allocated to FFR-guided PCI had FFR measurements of all stenotic arteries and PCI was done only if FFR was 0·80 or less. No one was masked to treatment assignment. The primary endpoint was major adverse cardiac events at 1 year, and the data for the 5-year follow-up are reported here. Analysis was by intention to treat. This trial is registered with ClinicalTrials.gov, number NCT00267774. After 5 years, major adverse cardiac events occurred in 31% of patients (154 of 496) in the angiography-guided group versus 28% (143 of 509 patients) in the FFR-guided group (relative risk 0·91, 95% CI 0·75-1·10; p=0·31). The number of stents placed per patient was significantly higher in the angiography-guided group than in the FFR-guided group (mean 2·7 [SD 1·2] vs 1·9 [1·3], pPCI in patients with multivessel disease. A strategy of FFR-guided PCI resulted in a significant decrease of major adverse cardiac events for up to 2 years after the index procedure. From 2 years to 5 years, the risks for both groups developed similarly. This clinical outcome in the FFR-guided group was achieved with a lower number of stented arteries

    Full Text Available Background/Aim. Intramyocardial bone marrow mononuclear cells (BMMNC implantation concomitant to coronary artery bypass grafting (CABG surgery as an option for regenerative therapy in chronic ischemic heart failure was tested in a very few number of studies, with not consistent conclusions regarding improvement in left ventricular function, and with a follow-up period between 6 months and 1 year. This study was focused on testing of the hypothesis that intramyocardial BMMNC implantation, concomitant to CABG surgery in ischemic cardiomyopathy patients, leads to better postoperative long-term results regarding the primary endpoint of conditional status-functional capacity and the secondary endpoint of mortality than CABG surgery alone in a median follow-up period of 5 years. Methods. A total of 30 patients with ischemic cardiomyopathy and the median left ventricular ejection fraction (LVEF of 35.9 ± 4.7% were prospectively and randomly enrolled in a single center interventional, open labeled clinical trial as two groups: group I of 15 patients designated as the study group to receive CABG surgery and intramyocardial implantation of BMMNC and group II of 15 patients as the control group to receive only the CABG procedure. All the patients in both groups received the average of 3.4 ± 0.7 implanted coronary grafts, and all of them received the left internal mammary artery (LIMA to the left anterior descending (LAD and autovenous to other coronaries. Results. The group with BMMNC and CABG had the average of 17.5 ± 3.8 injections of BMMNC suspension with the average number of injected bone marrow mononuclear cells of 70.7 ± 32.4 × 106 in the total average volume of 5.7 ± 1.5 mL. In this volume the average count of CD34+ and CD133+ cells was 3.96 ± 2.77 × 106 and 2.65 ± 1.71 × 106, respectively. All the patients were followed up in 2.5 to 7.5 years (median, 5 years. At the end of the follow-up period, significantly more patients from the group

    A proven advantage of radial over femoral arterial access has led to an increase in the number of interventions performed via radial artery access in patients with acute coronary syndromes. Both assessment of the pulse volume and the Allen's test are subjective and subject to investigator bias. An ultrasound examination of the forearm arteries provides important information about the anatomy of the forearm vessels, and indirectly also about the efficiency of collateral blood supply to the hand. It also enables determination of the relevant vessel diameter before the planned intervention, and may be used to assess local complications. To assess the morphology of forearm blood vessels and measure the diameter of both radial and ulnar arteries at the cannulation site using ultrasound imaging. We also aimed to identify potential vascular anomalies and local complications associated with radial artery puncture. The study included 109 patients with cardiologic indications for coronary angiography or coronary angioplasty. An ultrasound evaluation of forearm arteries was performed prior to the intervention, and the vascular anatomy was later verified by angiography during the procedure. Ultrasound measurements of the vessel diameter were also performed and local complications of the cannulation were assessed. Measurements were performed immediately after the procedure and at 30 days and 12 months. Fifty-nine right and 50 left forearm arteries were evaluated. Women were 29% of the study population. The mean patient age was 59.2 ± 7.9 years. The mean diameter of the right radial artery was 2.17 ± 0.54 mm, and the mean diameter of the left radial artery was 2.25 ± 0.43 mm. The measurements revealed gender-related differences in forearm artery diameter (p = 0.003). Vascular anomalies of the radial artery were identified by ultrasound examination in 10% of subjects. A significant dilatation of the cannulated blood vessel was observed which lasted up to 12 months. An

    Full Text Available Internal carotid artery (ICA supraclinoid segment aneurysms extending into the sellar region and leading to pituitary dysfunction are a rare occurrence. To date, long-term follow up of pituitary function 2 years post-treatment has never been reported. Herein, we present a case of pituitary dysfunction due to an unruptured ophthalmic segment internal carotid artery aneurysm and report improved 2-year follow-up results. A 76-year-old male presented with disturbed consciousness due to hyponatremia, which was caused by hypoadrenocorticism resulting from pituitary dysfunction complicated by hypogonadism and hypothyroidism. Computed tomography angiography revealed an intracranial aneurysm of the ophthalmic segment of the right ICA with an intrasellar extension. Thus, digital subtraction angiography and coil embolization were performed, followed by hormone replacement therapy. A 2-year follow-up revealed a partial improvement in the pituitary function, including complete restoration of thyroid-stimulating hormone level and other thyroid hormones levels, and partial restoration of testosterone levels, followed by discontinuation of thyroid hormone replacement therapy. However, the mechanisms of such pituitary dysfunction and the effects of various treatments, including clipping and coiling, on different hormones of pituitary function recovery remain unclear. A long-term follow-up of >2 years may elucidate the pituitary function recovery post-treatment and provide a medication adjustment for hormone replacement therapy.

    The aim of this study was to determine the predictive value of 64-slice computed tomography coronary angiography (CTCA) for major cardiac events in patients with suspected coronary artery disease (CAD). A total of 187 consecutive patients (119 men, age 62.5 {+-} 10.5 years) without known heart disease underwent single-source 64-slice CTCA (Somatom Sensation 64, Siemens) for clinical suspicion of CAD. Patients underwent follow-up for the occurrence of cardiac death, nonfatal myocardial infarction, unstable angina and cardiac revascularization. In total, 2,822 coronary segments were assessed. Forty-two segments (1.5%) were not assessable because of insufficient image quality. Overall, CTCA revealed absence of CAD in 65 (34.7%) patients, nonobstructive CAD (coronary plaque {<=}50%) in 87 (46.5%) patients and obstructive CAD (>50%) in 35 (18.8%) patients. A total of 20 major cardiac events (3 myocardial infarctions, 16 cardiac revascularizations, 1 unstable angina) occurred during a mean follow-up of 24 months. One noncardiac death occurred. Seventeen events occurred in the group of patients with obstructive CAD and three events occurred in the group of nonobstructive CAD. The event rate was 0% among patients with normal coronary arteries at CTCA. CTCA has a 100% negative predictive value for major cardiac events at 24-month follow-up in patients with normal coronary arteries. (orig.)

A total of 187 consecutive patients (119 men, age 62.5 ± 10.5 years) without known heart disease underwent single-source 64-slice CTCA (Somatom Sensation 64, Siemens) for clinical suspicion of CAD. Patients underwent follow-up for the occurrence of cardiac death, nonfatal myocardial infarction, unstable angina and cardiac revascularization. In total, 2,822 coronary segments were assessed. Forty-two segments (1.5%) were not assessable because of insufficient image quality. Overall, CTCA revealed absence of CAD in 65 (34.7%) patients, nonobstructive CAD (coronary plaque ≤50%) in 87 (46.5%) patients and obstructive CAD (>50%) in 35 (18.8%) patients. A total of 20 major cardiac events (3 myocardial infarctions, 16 cardiac revascularizations, 1 unstable angina) occurred during a mean follow-up of 24 months. One noncardiac death occurred. Seventeen events occurred in the group of patients with obstructive CAD and three events occurred in the group of nonobstructive CAD. The event rate was 0% among patients with normal coronary arteries at CTCA. CTCA has a 100% negative predictive value for major cardiac events at 24-month follow-up in patients with normal coronary arteries. (orig.)

    In order to distinguish benign from malignant nodules within the dissected neck area in patients with oral cancer during the follow-up period, we retrospectively evaluated the frequency and characteristic findings of fusiform-shaped nodules along the internal carotid artery observed by follow-up sonography. From 1997 to 2003, 52 patients with oral cancer, who underwent radical neck dissections, were enrolled in this study. The study cohort consisted of 33 males and 19 females ranging in age from 29 to 84 years (mean, 62.0 years). After neck dissection, every patient was examined repeatedly with sonography during the follow-up period at an interval of one month. CT and/or MRI were performed when clinically required. Any patient with recurrent neck mass was excluded from this study. In the 52 patients, fusiform-shaped nodules were observed in 10 patients (19%) by the follow-up sonography. The nodules were homogenously hypoechoic and the margin was well-demarcated except for the upper end. A hyperechoic core was clearly observed in every nodule, which showed a fatty density on post-contrast CT. On post-contrast MRI, the nodules enhanced markedly and the core showed hypointensity on fat saturated images. In conclusion, it was suggested that the fusiform-shaped nodules observed by follow-up sonography within the dissected neck area might be the superior cervical ganglion of sympathetic trunk. However, further studies are needed to disclose the true character of the nodules. (author)

    To report the results of treatment isolated iliac arterial aneurysms by interventional procedures. Over a period of 5 years, 7 isolated iliac artery aneurysms (4 in the common iliac artery, 3 in the internal iliac artery) in 7 patients (3 women, 4 men; mean age, 65.7 years) were treated using interventional procedures. The mean aneurysm size was 35 mm (range, 30-45 mm). The common iliac aneurysms were treated using a unilateral stent graft (2 balloon expandable, 2 self expandable) with coil embolization of the internal iliac artery (n = 3), except for 1 aneurysm that ruptured. Coil embolization alone was performed for aneurysms involving only the internal iliac artery (n = 3). All patients were treated successfully, except for 1 with an initial remnant of type 2 endoleak. There were no perioperative complications. No leakage or complication occurred at the mean follow up of 14 months (range 2-29 months). One patient with a ruptured aneurysm died of multi organ failure during the follow up period. Three aneurysms had decreased in size on follow up CT. Interventional procedures with stent grafting and coil embolization are safe and effective treatments for isolated iliac artery aneurysms.

    Duodenum-preserving pancreatic head resection according to Beger and the pylorus-preserving Whipple (ppWhipple) procedure were compared in patients with chronic pancreatitis (CP) in a randomized clinical trial. Perioperative data and short-term outcome have been reported previously. The present study evaluated long-term follow-up. Forty patients were enrolled originally, 20 in each group. Long-term follow-up included mortality, morbidity, pain status, occupational rehabilitation, quality of life (QoL), and endocrine and exocrine function at median follow-up of 7 and 14 years. One patient who had a ppWhipple procedure was lost to follow-up. There were five late deaths in each group. No differences were noted in pain status and exocrine pancreatic function. Loss of appetite was significantly worse in the ppWhipple group at 14 years' follow-up, but there were no other differences in QoL parameters examined. After 14 years, diabetes mellitus was present in seven of 15 patients who had the Beger procedure and 11 of 14 patients after ppWhipple resection (P = 0.128). After long-term follow-up of up to 14 years early advantages of the Beger procedure were no longer present. 2007 British Journal of Surgery Society Ltd. Published by John Wiley & Sons, Ltd.

    Background: Older patients with transposition of the great arteries who have undergone an atrial inversion procedure (ATRIAL-INV) are difficult to image by echocardiography. The surgical baffles are spatially complex. Objective: To test the hypothesis that two- and three-dimensional MRI can elucidate the spatially complex anatomy in this patient population. Materials and methods; Twelve patients with ATRIAL-INV, ages 16±4.5 years, underwent routine T1-weighted spin-echo axial imaging to obtain a full cardiac volumetric data set. Postprocessing created three-dimensional shaded surface displays and allowed for multiplanar reconstruction. Routine transthoracic echocardiography was available on all patients. Results: Three-dimensional reconstruction enabled complete spatial conceptualization of the venous pathways, and allowed for precise localization of a narrowed region in the upper limb of the systemic venous pathway found in two patients. This was subsequently confirmed on angiography. Routine MRI was able to image the full extent of the venous pathways in all 12 patients. Routine transthoracic echocardiography was able to visualize proximal portions of the venous pathways in eight (67%), the distal upper limb in five (42%), and the distal lower limb in four (33%) patients, and it was able to visualize the outflow tracts in all patients. Conclusion: Three-dimensional reconstruction adds important spatial information, which can be especially important in stenotic regions. Routine MRI is superior to transthoracic echocardiography in delineation of the systemic and pulmonary venous pathway anatomy of ATRIAL-INV patients at mid-term follow-up. Although transesophageal echocardiography is an option, it is more invasive. (orig.)

  16. Is mammary reconstruction with the anatomical Becker expander a simple procedure? Complications and hidden problems leading to secondary surgical procedures: a follow-up study.

    Debate over the role of Becker expander implants (BEIs) in breast reconstruction is still ongoing. There are no clear indications for BEI use. The main indications for BEI use are one-stage breast reconstruction procedure and congenital breast deformities correction, due to the postoperative ability to vary BEI volume. Recent studies showed that BEIs were removed 5 years after mammary reconstruction in 68% of operated patients. This entails a further surgical procedure. BEIs should not, therefore, be regarded as one-stage prostheses. We performed a case-series study of breast reconstructions with anatomically shaped Becker-35™ implants, in order to highlight complications and to flag unseen problems, which might entail a second surgical procedure. A total of 229 patients, reconstructed from 2005 to 2010, were enrolled in this study. Data relating to implant type, volume, mean operative time and complications were recorded. All the patients underwent the same surgical procedure. The minimum follow-up period was 18 months. During a 5-year follow-up, 99 patients required secondary surgery to correct their complications or sequelae; 46 of them underwent BEI removal within 2 years of implantation, 56 within 3 years, 65 within 4 years and 74 within 5 years. Our findings show that two different sorts of complications can arise with these devices, leading to premature implant removal, one common to any breast implant and one peculiar to BEIs. The Becker implant is a permanent expander. Surgeons must, therefore, be aware that, once positioned, the Becker expander cannot be adjusted at a later date, as in two-stage expander/prosthesis reconstructions for instance. Surgeons must have a clear understanding of possible BEI complications in order to be able to discuss these with their patients. Therefore, only surgeons experienced in breast reconstruction should use BEIs. Copyright © 2013 British Association of Plastic, Reconstructive and Aesthetic Surgeons. Published by

    Cognitive deficits in the domains of working memory (WM) and executive function are well documented following childhood arterial ischemic stroke (AIS). However, there are currently no evidence-based cognitive interventions for this population. Computerized, implicit WM training has been demonstrated to generate generalized cognitive gains for children with WM and attention deficits and for adults following brain injury. This study used a pilot design to investigate the efficacy and feasibility of such an intervention program (Cogmed WM Training) for a childhood AIS population. Outcomes were measured via psychometric assessment at preintervention and postintervention and again at 1-year follow-up. At longitudinal follow-up, participants were found to have significant and persistent cognitive difficulties, particularly with attention and response inhibition. Following the computerized, implicit WM intervention, a significant improvement in phonological-loop WM was seen; however, this improvement was not maintained after 12 months. No additional significant improvements on standardized psychometric outcome measures were seen either immediately or at 12-month follow-up. Findings of this pilot study therefore do not currently support Cogmed as an effective intervention for children with AIS but highlight the need for further research, including randomized, controlled trials, to investigate cognitive interventions for the childhood AIS population.

    Recent data support the renewed interest in hypertriglyceridemia as a possible important therapeutic target for cardiovascular risk reduction. This study was designed to address the question of all-cause mortality during extended follow-up of the BIP trial in patients stratified by baseline triglyceride levels. In the BIP trial 3090 patients with proven coronary artery disease were randomized to bezafibrate 400 mg/day or placebo. All-cause mortality data after 20 years of follow-up, were obtained from the National Israeli Population Registry. Patients with hypertriglyceridemia (triglycerides ≥200 mg/dL, n = 458) were equally distributed among the study groups (15 % in both placebo and bezafibrate groups). During follow-up 1869 patients died (952 in placebo vs. 917 in bezafibrate group). Following multivariate adjustment allocation to bezafibrate was associated with small but significant 10 % mortality risk reduction (HR 0.90; 95 % CI 0.82-0.98, p = 0.026). Variables associated with significantly increased mortality risk were history of a past MI, NYHA class, diabetes, age, higher BMI and glucose level. In patients with hypertriglyceridemia multivariate analysis demonstrated a 25 % all-cause mortality risk reduction associated with allocation to bezafibrate (HR 0.75, CI 95 % 0.60-0.94; p = 0.012). In patients without hypertriglyceridemia bezafibrate had no significant effect on long-term mortality. During long-term follow-up bezafibrate-allocated patients experienced a modest but significant 10 % reduction in the adjusted risk of mortality. This effect of bezafibrate was more prominent among patients with baseline hypertriglyceridemia (25 % mortality risk reduction).

    To evaluate the initial application and value of 64-slice multidetector computed tomography as an alternative diagnostic modality in the follow-up of young children with coronary artery aneurysm due to Kawasaki disease. Twelve boys (mean age 5.1 years, range 1.8-7.8 years) for follow-up (time range from 1.1 to 5.1 years) of known Kawasaki disease and coronary artery aneurysm underwent 64-slice MDCT ECG-gated coronary angiography. All data were acquired without breath holding. Two pediatric radiologists independently assessed image quality and the diameter of all coronary segments were measured for each patient. The number, position, shape and size of each coronary artery aneurysm were observed and compared with those of ECHO performed previously. A total of 118/156 segments permitted visualization with diagnostic image quality, the CT measurements showed good inter-observer and intra-observer reliability, coefficients were 0.93 and 0.88, respectively. A total of 30 coronary artery aneurysms were identified with measured mean of 7.5+/-3.8 mm in diameter, and of 12.4+/-9.1 mm in longitudinal lengths.10 tumors were small, 8 tumors were medium and 12 tumors were giant aneurysm. The affected segments included LM7/12(58.3%), 9/12(75%) of LAD1, 4/12(33.3%) of LAD2, 2/12(16.7%) of LCX1; 6/12(50%) of RCA1, 9/12(75%) of RCA2 and 4/12(33.3%) of RCA3, including affected two segments in 9 tumors and three segments in 1 tumor. Calcifications were found in 5 aneurysms and 3/5 with thrombosis; six stenotic segments were found. ECHO failed to detect 8 tumors with 2/8 in LAD, 1/8 in LCX and 5/8 in RCA, and those included 4 small aneurysms. The use of 64-slice MDCT angiography proved valuable for monitoring young children with Kawasaki disease. However, further study is necessary to specify the sensitivity and specificity of MDCT in the follow-up.

    A man with Marfan syndrome underwent a Bentall procedure for annuloaortic ectasia and severe aortic regurgitation at 43 years of age. Twenty-eight years after the Bentall procedure, he developed bilateral axillary artery aneurysms (length × diameter: right: 80 × 39 mm; left: 103 × 45 mm). Aneurysmectomy and reconstruction of the axillary artery were performed using an artificial vascular graft. Histological examination revealed cystic medial necrosis. The postoperative course was uneventful, but long-term follow-up is necessary. © The Author(s) 2014.

    PurposeThis study was designed to assess midterm outcome of uterine artery embolisation (UAE) for women with therapy-resistant adenomyosis using polyzene F-coated hydrogel microspheres.MethodsBetween September 2006 and January 2010, 29 consecutive women with adenomyosis (15 in combination with fibroids) were treated with UAE using polyzene F-coated hydrogel microspheres. Junction zone thickness was assessed with MRI at baseline and 3 months. Women filled out the uterine fibroid symptom and quality of life questionnaire at baseline, 3 months and after a mean clinical follow-up of 37 months (median 35, range 29–64 months).ResultsAt baseline, symptom severity score of 29 women was mean 67 (median 72, range 23–100). At 3 months, this score decreased to mean 22 (median 15, range 0–66) and mean 15 (median 17, range 0–34) at final follow-up. At final follow-up of mean 37 months (median 35, range 29–64 months), 22 of 29 (76 %) patients were asymptomatic. Of these 22 women, 3 underwent a second UAE at 6, 7, and 14 months. The remaining seven patients clinically improved but still had symptoms; one underwent a hysterectomy. There was no difference in outcome between women with pure adenomyosis and women with additional fibroids. The junction zone of 4 women with additional therapy was significantly thicker compared with the remaining 25 patients.ConclusionsIn women with therapy resistant adenomyosis, UAE using polyzene F-coated hydrogel microspheres resulted in 3 years preservation of the uterus in 28 of 29 (97 %) with good clinical outcome in the vast majority of patients. Initial thickness of the junction zone is related to additional therapy.

    To describe the role of magnetic resonance imaging (MRI) in establishing the indication for, planning, and following up uterine artery embolization (UAE) for treating symptomatic leiomyomas of the uterus on the basis of the current literature and our results. Retrospective analysis of the MRI findings obtained in 130 patients before and after UAE. Presentation of characteristic MRI features and their relevance in establishing the indication for, performing, and following up of UAE. Discussion of the results in conjunction with published data. The intermediate results of UAE reported in the literature show a successful improvement of leiomyoma-related symptoms in 82-94% of cases and an average reduction of leiomyoma size by 36-64%. The typical MRI appearance of degenerating leiomyomas is presented together with that of relevant differential diagnoses. MRI findings allow for establishing the indication for UAE by providing reliable information on the location, size, and number of uterine leiomyomas. Analysis of 60 patients of our study population showed solitary leiomyoma in 16% of cases, 2-10 leiomyomas in 47%, and over 10 in 37%. Subserosal, pedunculated leiomyomas cannot be treated by UAE; these were present in 5% of the patients. MR angiography is useful in assessing pelvic vascular anatomy before the intervention and identifies collateral vascular supply to the uterus. Contrast-enhanced imaging is suitable for monitoring successful devascularization following embolization and evaluating complications. (orig.) [de

    Cardiovascular (CV) disease (CVD) is a leading cause of morbidity and mortality worldwide. Most CV events are caused by atherosclerosis. Diabetes and impaired glucose tolerance are associated with greater carotid intima-media thickness (IMT) and increased risk for CVD. The present study examined if common carotid artery IMT (CCAIMT) is predictive of CVD irrespective of glucose tolerance category and glycated hemoglobin (HbA1c) in a sample of 639 women with different glucose tolerance categories. During 7-year follow-up, 30 events in the cardiac and 32 events in the cerebral territory were documented. Unadjusted Cox hazard models showed that CCAIMT, glucose tolerance category, and HbA1c were associated with increased risk. An adjusted and extended model, including CCAIMT, glucose tolerance category, and HbA1c, showed that CCAIMT was still associated with events with an almost unchanged hazard ratio. In conclusion, this study suggests that CCAIMT is predictive of major CV events during 7-year follow-up, irrespective of glucose tolerance category, HbA1c, and other established risk factors in a cohort of 64-year-old women.

    Abnormal vessels and accompanying nerves are possible sources of pain with lateral epicondylitis. The purpose of this study was to describe the safety and efficacy of transcatheter arterial embolization (TAE) for lateral epicondylitis resistant to conservative treatment. This prospective study was conducted in 24 patients with lateral epicondylitis resistant to conservative treatments for more than 3 months, with a symptom duration longer than 6 months, and with moderate to severe pain who were treated with TAE between March 2013 and October 2014.

    Objective: To evaluate the rate of unnecessary follow-up procedures recommended by radiologists using a CAD-system. Materials and methods: 185 patients (740 images) were consecutively selected from three groups (36 histologically proven cancers=group 1; 49 histologically proven benign lesions=group 2 and 100 screening cases (4 years-follow up=group 3). Mammograms were evaluated by a CAD system (Second Look [reg] , CADx, Canada). Five blinded radiologists assessed the images without/with CAD outputs. Diagnostic decisions were ranked from surely benign to surely malignant according to BIRADS classification, follow-up procedures were recommended for each observed lesion (a, screening; b, short interval follow-up examination in 6 months; c, pathologic clarification). Results: CAD-system detected 32/36 cancers (88.9%) (FP-rate: 1.04 massmarks and 0.27 calcmarks/image). The following values were reached by all observers without/with CAD in the mean: Sensitivity 80.6/80.0%, specificity 83.2/86.4%, PPV 53.1/58.1%, and NPV 94.6/94.7%. Observers described a similar number of additional lesions without/with the use of CAD (325/326). Whereas the number of unnecessary short-time follow up recommendations increased in all case-subgroups with CAD: 40.8/42.9% (group 1), 35.6/38.1% (group 2), 44.7/46.8% (group 3), respectively, the number of recommended biopsies decreased in all subgroups: group 1: 34.7/27.1%; group 2: 47.4/41.5%, group 3: 33.3/22.0%, respectively. Conclusion: In this rather small population additional usage of CAD led to a lower rate of unnecessary biopsies. The observed decrease of recommended unnecessary biopsies due to the usage of CAD in the screening group suggests a potential financial benefit by using CAD as diagnostic aid

    Long-term clinical symptoms, including extrapyramidal signs, and magnetic resonance (MR) imaging studies were retrospectively analyzed in 21 patients with good outcome (modified Rankin scale scores 0-2) after successful recanalization of occluded major arteries by intra-arterial thrombolysis with mechanical disruption. Changes in high intensity areas (HIAs) and cerebral atrophy in the ischemic hemisphere were evaluated on follow-up fluid-attenuated inversion recovery MR images. Extrapyramidal signs, short-stepped gait and/or masked face, were observed in 12 of 21 patients during the follow-up period (11 to 68 months, mean 42 months). Enlargement of HIA was demonstrated in 10 of 18 patients undergoing follow-up MR imaging. Cerebral atrophy in the ischemic hemisphere was revealed on the follow-up MR images in all 18 patients. In nine patients with small infarctions, 20 ml or less on computed tomography scans, cerebral atrophy progressed more rapidly in four patients with extrapyramidal signs compared to the other five patients without extrapyramidal signs (p<0.05). More than half of the patients with good outcome showed extrapyramidal signs. Extrapyramidal signs in patients with small infarction may indicate rapid progression of cerebral atrophy. The occurrence of extrapyramidal signs might be related to delayed neuronal death in atrophic areas. (author)

    Anterior instability in rugby players is characterized by the common finding of a bony lesion, which has been identified as a potential cause of recurrence after soft-tissue reconstruction. The Latarjet-Patte procedure is effective in the treatment of recurrent anterior instability in collision sports such as rugby union. We retrospectively assessed 34 rugby players (37 shoulders) stabilized with the Latarjet-Patte procedure. The mean follow-up was 12 years. All patients underwent clinical and radiographic assessment preoperatively and at final follow-up. Functional evaluation was performed with the Walch-Duplay and Rowe scores. A visual analog scale score for the evaluation of pain and the subjective shoulder value were recorded. In addition, all patients completed a questionnaire regarding the return to playing rugby. No recurrence of either dislocation or subluxation occurred. Persistent apprehension on clinical examination was present in 5 patients (14%). A bony lesion of the glenoid was present in 73% and a Hill-Sachs lesion in 68%. Sixty-five percent of the patients returned to playing rugby; only 1 patient did not return to playing rugby because of his shoulder. The mean Walch-Duplay and Rowe scores were 86 and 93 points, respectively. The mean subjective shoulder value was 90%. Radiographic healing of the bone block was observed in 89% of cases. At final follow-up, 11 patients (30%) had minor arthritic changes, with no cases of moderate or severe arthritis. The Latarjet-Patte procedure provides a reliable method for stabilizing the shoulder, resulting in a return to playing rugby in a high number of cases without increasing the risk of long-term arthritic degradation.

    To compare uterine artery embolisation (UAE) and hysterectomy for the treatment of leiomyomas at 2-year follow-up in a prospective, randomised, single-centre study. Fifty-seven symptomatic patients were randomised to UAE (n = 27) or hysterectomy (n = 30). Complications, recovery, reinterventions and satisfaction with treatment were recorded. Primary endpoint was improvement of symptoms. Analyses were performed by intent-to-treat and per protocol. Two hysterectomy patients (7%) developed major complications. Hospital discharge occurred earlier after UAE than after hysterectomy (p < 0.001). Length of sick leave was longer after hysterectomy than after UAE (p < 0.001). Twenty-two (82%) UAE patients and 28 (93%) hysterectomy patients reported overall relief of symptoms (p = 0.173). In 12/18 (67%) UAE patients menorrhagia was completely resolved or reduced. Improvement of pressure symptoms was reported significantly more by UAE patients than by hysterectomy patients (19/20 [95%] versus 18/26 [69%], respectively; p = 0.029). Five (19%) UAE patients underwent additional interventions due to worsening symptoms. Twenty-four (89%) UAE patients and 29 (97%) hysterectomy patients would have chosen treatment again (p = 0.336). UAE gave relief of symptoms (apart from menorrhagia) comparable to hysterectomy with less severe complications, but with an increased rate of secondary interventions. UAE may be the preferable treatment especially for patients with pressure symptoms. (orig.)

    Interleukin-6 (IL-6) and tissue factor (TF) are elevated after myocardial ischemia during dobutamine stress echo (DSE). We examined the incremental prognostic value of IL-6 or TF measured during DSE over echocardiographic and clinical factors in patients with chronic coronary artery disease (CAD). We studied 106 patients with angiographically documented CAD. IL-6 and TF were measured at rest, peak, and during recovery. A wall motion score index was calculated. Fifty-seven (54%) patients had ischemia at DSE. During follow-up (63.7 +/- 20 months), 36 patients (33%) had an adverse event (12 cardiac deaths, 24 acute coronary events). Patients with events had a higher peak IL-6 (P = .02) but similar rest and recovery IL-6 than those without. Patients with peak IL-6 > or =3.14 pg/mL (upper tertile) had a hazard ratio of 2.7 (95% CI 1.44-5.37) (P statistic from 0.66 to 0.70 (P = .04). The addition of peak IL-6 further increased the model's c statistic to 0.75 (P = .04). Tissue factor was not related with cardiac events. Interleuikin-6 levels measured during the peak phase of DSE incrementally contribute to risk stratification in patients with chronic CAD.

    Objective: Complicated aneurysms located in the cisternal segment of the internal carotid artery(ICA-CSA) present unique therapeutic difficulties. This study is to discuss the feasibility of the Willis stent-graft in treating complicated ICA-CSA by comparing its effect with that of coiling therapy. Methods: Willis covered stents were employed in 19 complicated ICA-CSAs (group A), while coils were used in 17 complicated ICA-CSAs (group B). Follow-up angiography was performed to investigate aneurysm recurrence, endoleak and parent artery (PA) stenosis. Kaplan-Meier curves were constructed to compare the recurrence-free and PA stenosis-free rate in both groups. Results: Total exclusion was immediately achieved in 13 ICA-CSAs and minor endoleaks presented in 5 cases in group A. Total or near-total occlusion was achieved in 7 ICA-CSAs, subtotal occlusion in 8 and partial occlusion in 2 cases in group B after coiling. Acute thrombosis occurred in 1 patient in either group and re-hemorrhage happened in 1 patient after coiling. Follow-up angiography in group A revealed that 16 ICA-CSAs were completely isolated, with two parent arteries showing mild in-stent stenosis. Eighteen months after the procedure, Kaplan-Meier analysis showed that the recurrence-free rate was 93.3% and 50%, while the stenosis-free rate of parent artery was 87.5% and 100% in group A and in Group B, respectively. In group A and group Bthe clinical neurological symptoms were fully recovered in 9 and 9, obviously improved in 3 and 5, unchanged in 2 and 2, and aggravated in one and 0 patients, respectively. Conclusion: The implantation of Willis stent-graft is a feasible endovascular therapy for complicated ICA-CSAs. When the parent artery is very tortuous or when the risk that a main collateral branch may be wrongly covered and occluded is present, the implantation of Willis covered stent can not be taken as the treatment of first choice.

    The study aim was to evaluate the long-term clinical outcomes of the modified Bentall procedure (MBP) with a mechanical conduit. Between 1993 and 2014, a total of 249 patients (mean age 62 ± 12 years; range: 25-87 years) underwent a MBP at the authors' institution. The main indication was annuloaortic ectasia in 102 patients (41%), followed by acute aortic dissection in 82 patients (33%); moderate to severe aortic regurgitation was present in 79% of cases. A bicuspid aortic valve was found in 17% of patients, and Marfan syndrome in 7%. The mean NYHA functional class was 2.5 ± 1.1. Concomitant procedures were performed in 36 patients (14%). The mean follow up was 8.7 ± 5.0 years (range: 0.3-21.5 years) and was 99% complete. The total follow up was 6.475 patient-years (pt-yr). Operative mortality was 3% in elective cases. Age, prolonged cardiopulmonary bypass times and mechanical ventilation >96 h were independent risk factors for early mortality. Actuarial survival at 15 and 20 years was 62% and 60%, respectively. Risk factors for late mortality were age and emergency operation. Actuarial freedom from thromboembolism (linearized incidence 0.93%/pt-yr) was 82% at 15 years, and 74% at 20 years. Seven patients required reoperation (0.38%/pt-yr), with an actuarial freedom from reoperation of 91% at 15 years and 87% at 20 years. The incidence of overall valve-related complications was 0.32%/pt-yr, with actuarial freedoms of 94% at 15 and 20 years. The MBP has shown excellent long-term results with a low incidence of procedure-related complications up to 20 years postoperatively. For this reason, it is considered to be a valid option for the treatment of aortic root disease, whenever valvesparing procedures are not indicated.

    Many surgical procedures have been reported for rotator cuff tears. We adopted the modified transosseous-equivalent procedure, also termed ''surface-holding repair with transosseous sutures,'' and demonstrated that this procedure has a biomechanical advantage regarding the concentration of stress on the tendon stump. This study aimed to evaluate the clinical and structural outcomes of this technique, which has been demonstrated by postoperative magnetic resonance imaging (MRI) to produce high intact rates. Twenty-nine massive rotator cuff tears involving at least two tendons were treated by open repair using this procedure. Twenty-four patients were evaluated at an average of 43.2 months (range 24-71) postoperatively (the follow-up rate was 83.8%). The pre- and postoperative clinical outcomes were examined using the scoring system of the Japanese Orthopedic Association (JOA score). In an A-P radiograph, the presence of osteoarthritis (OA) of the glenohumeral joint and upward migration of the humeral head were compared pre- and postoperatively. The repair integrity of the cuff tendon was evaluated by applying Sugaya's classification to the postoperative MRIs. The JOA score improved from 42.8 points preoperatively to 89.3 points at final follow-up. Radiographic examination showed that OA progressed in 16.7% and upward migration of the humeral head progressed in 20.8%. Postoperative MRI scans revealed 14 shoulders with type 1 repair based on Sugaya's classification, 4 shoulders with type 2, 4 shoulders with type 3, 2 shoulders with type 4, and no shoulders with a type 5 repair. Although osteoarthritis of the glenohumeral joint and upward migration of the humeral head had both progressed postoperatively in some cases, postoperative MRI scans revealed that 91.7% of the repairs resulted in a continuous rotator cuff. Therefore, this technique produces a high healing rate. (author)

    Interventional radiology (IR) has evolved into a full-fledged clinical specialty with attendant patient care responsibilities. Success in IR now requires development of a full clinical practice, including consultations, inpatient admitting privileges, and an outpatient clinic. In addition to technical excellence and innovation, maintaining a comprehensive practice is imperative for interventional radiologists to compete successfully for patients and referral bases. A structured approach to periprocedural care, including routine follow-up and early identification and management of complications, facilitates efficient and thorough management with an emphasis on quality and patient safety.

    Objective: To discuss the clinical value of MR diffusion-weighted imaging (DWI) in the follow-up of hepatocellular carcinoma after transcatheter arterial chemo embolization (TACE). Methods: MR DWI was performed in 16 patients with hepatocellular carcinoma after receiving TACE. The DWI findings were compared with DSA and/or CT signs. The mean apparent diffusion coefficient (ADC) value of each lesion was determined separately, and the mean ADC value of intra-hepatic metastatic lesion was compared with that of the primary lesion. Results: A total of 18 lesions were revealed in DSA, of which satisfactory iodinated oil deposit was seen in 11 (satisfactory group) and poor deposit in 7 (poor group). After TACE, the mean ADC value of normal hepatic parenchyma showed no obvious changes when compared to its preoperative value (t = 0.54, P > 0.05). The mean ADC value obtained in poor group was significantly lower than that obtained in satisfactory group (t = 4.81, P < 0.01). In satisfactory group the preoperative ADC values were higher than the postoperative ones (t = 6.81, P < 0.01), while in poor group no significant difference was found between preoperative and postoperative ADC values. In addition, twelve intra-hepatic metastases were detected on DWI. Statistically significant difference in the mean ADC value existed between the metastatic lesions and the primary lesions (t = 4.61, P < 0.01). Conclusion: DWI is very sensitive in detecting hepatic metastatic lesions and, therefore, can be used to evaluate the therapeutic effect of TACE. (authors)

    In discharged patients with heart failure (HF), diverse conditions can intervene to worsen outcome. We would investigate whether such factors present on hospital admission can affect long-term mortality in subjects hospitalized for acute HF. One hundred twenty-three consecutive patients hospitalized for acute HF (mean age 74.8 years; 57% female) were recruited and followed for 36 months after hospitalization. At multivariate Cox model, only inferior vena cava (IVC) diameter and mean arterial pressure (MAP) registered bed-side on admission, resulted, after correction for all confounders factors, the sole factors significantly associated with a higher risk of all-cause mortality in long-term (HR 1.06, p=0.0057; HR 0.97, p=0.0218; respectively). Study population was subdivided according to median values of IVC diameter (23 mm) and MAP (93.3 mm Hg). The Kaplan–Meier curve showed that HF patients with both IVC ≥ 23 mm and MAP b93.3 mm Hg on admission had reduced probability of survival free from all-cause death (log rank p = 0.0070 and log rank p = 0.0028, respectively). In patients hospitalized for acute HF, IVC diameter, measured by hand-carried ultrasound (HCU), and MAP detected on admission are strong predictors of long-term all-cause mortality. The data suggest the need for a careful clinical-therapeutic surveillance on these patients during the post-discharge period. IVC diameter and MAP can be utilized as parameters to stratify prognosis on admission and to be supervised during follow-up. Copyright © 2015 European Federation of Internal Medicine.

We analyzed the data of 10-year prospective follow-up of the patient with AS (n = 278, psoriatic arthritis (n = 85 and healthy controls (n = 150 without any cardiovascular diseases. All groups were comparable in regard to cardiovascular risk factors. During these 10 years all new cases of CAD (verified by cardiologist in the study population were tracked.Results. New cases of CAD were fixed in 64 out of 278 patietns with AS and in 16 out of 150 controls (p = 0.0017. Using log-rank MantelCox test and logrank test for trend we demonstrated statistically significant differences in CAD incidence between patients without spondyloarthritis (SpA and patients with AS and PsA (p < 0,0001. The risk of CAD development was higher in PsA group than in the control group; relative risk was 4.16 (95 % confidence interval (CI 2.36–7.33, RR 6.1 (95 % CI 3.05–12.44 (p < 0.05. Increased risk of myocardial infarction was observed both in patients with AS (RR 4.98; 95 % CI 1.54–6.12 and patients with PsA (RR 5.2; 95 % CI 2.4–7.8 comparing to healthy controls. There was no significant difference between the AS-group and the control group in terms of risk of stenocardia development (p > 0.05.Conclusion. The risk of exertional stenocardia in patients with AS was not higher than that in individuals without SpA. However, patients with AS have higher risk of myocardial infarction than those without SpA. PsA patients have increased risk of CAD development comparing to healthy controls and individuals with AS.

    The optimal prosthesis option for aortic valve replacement in adult patientsreplacement (n=190; 86%) or the subcoronary technique (n=31; 14%). There were 169 patients with bicuspid valves and 33 redo operations including previous aortic valve repair (n=6) and replacement (n=9) for severe AS. Demographic, preoperative, postoperative and longitudinal clinical and echocardiographic data were collected prospectively. The median and mean follow-up were 11.4 years (range: 1-20.1 years) and 10.1±5.9 years, respectively. The follow-up was complete in all patients. Kaplan-Meier actuarial survival analysis was performed to assess long-term survival, freedom from reoperation for autograft and/or homograft failure and freedom from autograft valve insufficiency. Cox regression risk analysis was performed to identify factors associated with autograft or homograft reoperations. The perioperative mortality rate was 0.9% (n=2). The incidence rate of early reoperation for bleeding was 5.9%. The actuarial survival rate at 10 and 15 years following surgery was 92.1 and 90.5%, respectively. Ross-related reoperations occurred in 21 patients during follow-up: autograft dysfunction (n=9), homograft dysfunction (n=6) and both (n=6). The rate of freedom from Ross-related reoperation was 94.7 and 87.7% at 10 and 15 years, respectively. The rate of freedom from reoperation for autograft failure was 97.6 and 91.5%, the rate of freedom from reoperation for homograft failure was 95.7 and 90.8%, and the rate of freedom from moderate or severe autograft regurgitation was 94.1 and 85.6% at 10 and 15 years, respectively. Compared with available aortic bioprosthetic alternatives in young adults with severe AS, the Ross procedure provides an excellent long-term option for patients with predominant severe AS who seek a durable operation without anticoagulation. © The Author 2014.

    Background/Purpose: The ORBIT I trial, a first-in-man study, was conducted to evaluate the safety and performance of the orbital atherectomy system (OAS) in treating de novo calcified coronary lesions. Methods/Materials: Fifty patients were enrolled between May and July 2008 based on several criteria, and were treated with the OAS followed by stent placement. The safety and performance of the OAS were evaluated by procedural success, device success, and overall major adverse cardiovascular event (MACE) rates, including cardiac death, myocardial infarction (MI) and need for target lesion revascularization (TLR). Our institution enrolled and treated 33 of the 50 patients and continued follow-up for 5 years. Results: Average age was 54 years and 91% were males. Mean lesion length was 15.9 mm. Device success was 100%, and average number of orbital atherectomy devices (OAD) used per patient was 1.3. Stents were placed directly after OAS in 31/32 patients (96.9%). All stents (average stent per lesion 1.1) were successfully deployed with 0.3% residual stenosis. The overall cumulative MACE rate was 6.1% in-hospital, 9.1% at 30 days, 12.1% at 6 months, 15.2% at 2 years, 18.2% at 3 years and 21.2% at 5 years (4 total cardiac deaths). None of the patients had Q-wave MIs. Angiographic complications were observed in 5 patients. No flow/slow flow due to distal embolization was observed. Conclusions: The ORBIT I trial suggests that OAS treatment continues to offer a safe and effective method to change compliance of calcified coronary lesions to facilitate optimal stent placement in these difficult-to-treat patients

    The purpose of this study was to assess the therapeutic efficacy and immediate and long-term safety of expanded-tetrafluoroethylene covered stent-grafts for transjugular intrahepatic portosystemic shunts in patients with portal hypertension-related complications. A cohort of 56 patients suffering from severe portal hypertension-related complications underwent implantation of an expanded-polytetrafluoroethylene-covered stent-graft. All patients suffered from severe liver cirrhosis graded Child-Pugh A (n=8; 16%), B (n=13; 21%) or C (n=35; 63%). In 44 patients, the stent-graft was placed during the initial TIPS procedure (de novo TIPS); in the other 12 patients, the stent-graft was placed to repermeabilize the previously placed bare stent (TIPS revision). Follow-up was performed with clinical assessment, duplex ultrasound and, if abnormal or inconclusive, with invasive venography and pressure measurements. Per- en immediate post-procedural complications occurred in four patients (4/56, 7%). None of them was lethal. During follow-up, stent occlusion appeared in one patient and stenosis in two; no recurrence of bleeding was noted in all patients treated for variceal bleeding (n=28), and 24 of the 28 patients (86%) suffering from refractory ascites and/or hepatic hydrothorax were free of regular paracenteses and/or drainage of pleural effusion after shunt creation. The 30-day and global mortality for the total study population (n=56) was, respectively, 7% (n=4) and 28.5% (n=16). In the patient subgroup with variceal bleeding (n=28), 30-day mortality was 3.5% (n=1) and global mortality 14.2% (n=4). In the ascites and/or hydrothorax subgroup (n=28), 8.1% (n=3) mortality at 30 days was found and global mortality was 32.4% (n=12). In 10 patients of the 56 studied patients (18%), isolated hepatic encephalopathy occurred, which was lethal in 4 (Child C) patients (7%). Three of these four patients died within the 1st month after TIPS placement. A very high primary patency rate

    Full Text Available Background. Several characteristics appear to be important for estimating the likelihood of reentering the workforce after surgery. The aim of the present study was to describe work status in a two-year time period around the time of cardiac surgery and estimate the probability of returning to the workforce. Methods. We included 681 patients undergoing coronary artery bypass grafting and/or heart valve procedures from 2003 to 2007 in the North Denmark Region. We linked hospital data to data in the DREAM database which holds information of everyone receiving social benefits. Results. At the time of surgery 17.3% were allocated disability pension and 2.3% were allocated a permanent part-time benefit. Being unemployed one year before surgery reduced the likelihood of return to the workforce (RR=0.74 (0.60–0.92 whereas unemployment at the time of surgery had no impact on return to the workforce (RR=0.96 (0.78–1.18. Sickness absence before surgery reduced the likelihood of return to the workforce. Conclusion. This study found the work status before surgery to be associated with the likelihood of return to the workforce within one year after surgery. Before surgery one-fifth of the population either was allocated disability pension or received a permanent part-time benefit.

    Recent development of sophisticated intensive care technique for use in newborn infants with the respiratory distress syndrome (RDS) has resulted in changes in the therapeutic strategies and moved the problem of neonatal survival into the realm of new therapeutic realities. At present, the mechanical ventilation methods form an integral part of the intensive care strategy of infants with RDS. They have come to the forefront of infant care because of their successful use in ventilatory support and children survival where other therapeutic modalities have failed. The present prospective observational longitudinal study was designed to assess the real-time convenience, reliability and accuracy of the changes in the oxygenation index (OI), arterial-to-alveolar oxygen tension ratio (a/A PO2) and alveolar-arterial oxygen gradient (A-a)DO2 in ventilator-dependent neonates with RDS, to analyze their feasibility and potential information yield in oxygen inhalation therapy as well as their prognostic implications and predictive value. Twenty neonates with RDS, heralded by respiratory failure which necessitated the initiation of oxygen inhalation therapy and ventilatory support within 24 hours of birth, were enrolled in the study. Ten of the infants survived and the remaining ten died. OI, (a/A PO2) and (A-a)DO2 were followed up sequentially and thoroughly analyzed as the primary outcome measures of the study. The indices were calculated on the basis of the complete monitoring of the ventilatory equipment parameters and acid-base status carried out on an hourly basis. Our results show that: 1. The combination of three indexes (OI, (a/A)PO2 and (A-a)DO2 we propose is a useful discriminating predictor of neonatal lung maturity reflecting arterial blood gas status in ventilator-dependent neonates with RDS. 2. The indices detect the efficacy of the modern conventional ventilatory support with real-time convenience and reliable accuracy forming the cornerstone of clinical decision

    Full Text Available OBJECTIVE: To assess the in-hospital results and clinical follow-up of young patients (< 50 years with multivessel coronary artery disease undergoing stent implantation in native coronary arteries and to compare their results with those of patients with single-vessel coronary artery disease. METHODS: We retrospectively studied 462 patients undergoing coronary stent implantation. Patients were divided into 2 groups: group I (G-I - 388 (84% patients with single-vessel coronary artery disease; and group II (G-II - 74 (16% patients with multivessel coronary artery disease. RESULTS: The mean age of the patients was 45±4.9 years, and the clinical findings at presentation and demographic data were similar in both groups. The rate of clinical success was 95% in G-I and 95.8% in G-II (P=0.96, with no difference in regard to in-hospital evolution between the groups. Death, acute myocardial infarction, and the need for myocardial revascularization during clinical follow-up occurred in 10.1% and 11.2% (P=0.92 in G-I and G-II, respectively. By the end of 24 months, the actuarial analysis showed an event-free survival of 84.6 % in G-I and 81.1% in G-II (P=0.57. CONCLUSION: Percutaneous treatment with coronary stent implantation in young patients with multivessel disease may be safe with a high rate of clinical success, a low incidence of in-hospital complications, and a favorable evolution in clinical follow-up.

    We examined the association between neighborhood convenience stores and diet outcomes for 20 years of the Coronary Artery Risk Development in Young Adults study. We used dietary data from the Coronary Artery Risk Development in Young Adults study years 1985-1986, 1992-1993, and 2005-2006 (n = 3299; Birmingham, AL; Chicago, IL; Minneapolis, MN; and Oakland, CA) and geographically and temporally matched neighborhood-level food resource and US Census data. We used random effects repeated measures regression to estimate associations between availability of neighborhood convenience stores with diet outcomes and whether these associations differed by individual-level income. In multivariable-adjusted analyses, greater availability of neighborhood convenience stores was associated with lower diet quality (mean score = 66.3; SD = 13.0) for participants with lower individual-level income (b = -2.40; 95% CI = -3.30, -1.51); associations at higher individual-level income were weaker. We observed similar associations with whole grain consumption across time but no statistically significant associations with consumption of sugar-sweetened beverages, artificially sweetened beverages, snacks, processed meats, fruits, or vegetables. The presence of neighborhood convenience stores may be associated with lower quality diets. Low-income individuals may be most sensitive to convenience store availability.

A baixa adesão e o abandono do tratamento estão entre os principais obstáculos às estratégias individuais de controle. Estudam-se os motivos do abandono do seguimento médico em uma coorte de pacientes em tratamento de hipertensão arterial, em serviço de atenção primária à saúde, acompanhados por um período de quatro anos. Foram realizadas entrevistas semiestruturadas com cinquenta pessoas com hipertensão que abandonaram o seguimento médico. As respostas foram analisadas mediante a técnica de análise temática de conteúdo. Os motivos relatados para o abandono do seguimento mostraram predomínio de razões ligadas ao próprio serviço de saúde - sua organização, estrutura e a relação médico-paciente - e, ainda, tratamento em outro serviço de saúde. Razões de natureza psicossocial, como a ausência de sintomas, a melhora e/ou a normalização da pressão arterial e o consumo de álcool também contribuíram para o abandono do cuidado. Estudar os motivos do abandono na perspectiva do próprio sujeito permitiu verificar a riqueza e diversidade de problemas envolvidos no cuidado requerido.Arterial hypertension is a relevant public health problem as it is a risk factor for cardiovascular diseases, the major cause of mortality in Brazil.

    The aim of this study was to report on 15-year long-term results of a randomized controlled trial comparing extended drainage procedure (Frey) and classical resectional procedure [pylorus-preserving pancreatoduodenectomy (PD)] in patients with chronic pancreatitis. Chronic pancreatitis is a common inflammatory disease with a prevalence of 10 to 30 cases per 100,000 inhabitants. It is characterized by the progressive conversion of pancreatic parenchyma to fibrous tissue. Different surgical procedures are used in treatment of persistent pain. Sixty-four patients suffering from chronic pancreatitis with inflammatory mass in the pancreatic head were randomly assigned in 2 treatment groups (PD, n = 32) and (Frey, n = 32). The perioperative course of the randomized controlled trial and the 7 years follow-up have been previously published. All participating patients were contacted with a standardized, validated questionnaire (EORTC QLQ C30) to evaluate the long-term survival, quality-of-life pain, and exocrine and endocrine function. In the 15-year long-term follow-up, the pain control was good and comparable between both groups, but the quality of life was better after Frey procedure in regard of the physical status [PD: 100 (0-100) vs PD: 60 (0-100) (P = 0.011)]. No significant differences in terms of the Pain Score were detected between both groups [PD: 7 (0-100) vs Frey 4 (0-100) P = 0.258]. Seven patients after Frey OP and 6 patients after PD were free of pain. Analyzing the postoperative overall survival, a higher long-term mortality was found after PD (53%) than that found after Frey procedure (30%) resulting in a longer mean survival (14.5 ± 0.8 vs 11.3 ± 0.8 years; P = 0.037). No correlation between endocrine or exocrine pancreatic function and pain was found, whereas continuous alcohol consumption was associated with poorer outcome regarding quality of life (P treatment of chronic pancreatitis.

    Our aim was to evaluate the diagnostic accuracy of 256-slice, high-pitch mode multidetector computed tomography (MDCT) for coronary artery bypass graft (CABG) patency. Eighty-eight patients underwent 256-slice MDCT angiography to evaluate their graft patency after CABG surgery using a prospectively synchronized electrocardiogram in the high-pitch spiral acquisition mode. Effective radiation doses were calculated. We investigated the diagnostic accuracy of high-pitch, low-dose, prospective, electrocardiogram-triggering, dual-source MDCT for CABG patency compared with catheter coronary angiography imaging findings. A total of 215 grafts and 645 vessel segments were analyzed. All graft segments had diagnostic image quality. The proximal and middle graft segments had significantly (P < 0.05) better mean image quality scores (1.18 ± 0.4) than the distal segments (1.31 ± 0.5). Using catheter coronary angiography as the reference standard, high-pitch MDCT had the following sensitivity, specificity, positive predictive value, and negative predictive value of per-segment analysis for detecting graft patency: 97.1%, 99.6%, 94.4%, and 99.8%, respectively. In conclusion, MDCT can be used noninvasively with a lower radiation dose for the assessment of restenosis in CABG patients.

    A retrospective single-centre study was focused on the long-term outcome after different patello-femoral (PF) realignment procedures. Thirty-nine patients treated for recurrent PF instability were examined after a mean post-operative time of 22.5 years. Their 78 knees were divided into: non-operated knees (NON-OPERATED)-N = 24, isolated proximal procedures (PROXIMAL)-N = 22, isolated distal procedures (DISTAL)-N = 10, and combined procedures (COMBINED)-N = 22. PF-related medical history together with clinical, subjective (KOOS and Kujala scores), and radiographic (Caton-Deschamps PF height index, Kellgren-Lawrence scale for tibio-femoral OA, and Iwano classification for PF OA) evaluation was conducted. PF re-dislocation rate was comparable between PROXIMAL (36%), DISTAL (20%), and COMBINED (32%). Isolated proximal procedures revealed less central patella positions (PROXIMAL 64%; DISTAL 90%; COMBINED 95%) and more frequent PF apprehension test (PROXIMAL 82%; DISTAL 40%, COMBINED 50%). KOOS and Kujala scores were similar in all three surgical subgroups, but significantly lower than in NON-OPERATED. Patellas were positioned lower after DISTAL, 0.8 (0.5-1.0) or COMBINED, 0.9 (0.4-1.3). Kellgren-Lawrence scores ≥2 were found in 42% NON-OPERATED, 37% PROXIMAL, 70% DISTAL, and 59% COMBINED, whereas Iwano classification ≥2 was confirmed in 46% NON-OPERATED, 64% PROXIMAL, 80% DISTAL, and 86% COMBINED. High PF re-dislocation rates together with a very high incidence of PF OA indicate that PF realignment strategies used traditionally had failed to reach their long-term expectations. The transfer of tibial tuberosity resulted in more constrained PF joints than isolated proximal procedures which allowed for more residual PF instability. Distal procedures additionally increased the likelihood for tibio-femoral OA. III.

    How well can a single baseline ultrasound assessment of fibroid burden (presence or absence of fibroids and size of largest, if present) predict future probability of having a major uterine procedure? During an 8-year follow-up period, the risk of having a major uterine procedure was 2% for those without fibroids and increased with fibroid size for those with fibroids, reaching 47% for those with fibroids ≥ 4 cm in diameter at baseline. Uterine fibroids are a leading indication for hysterectomy. However, when fibroids are found, there are few available data to help clinicians advise patients about disease progression. Women who were 35-49 years old were randomly selected from the membership of a large urban health plan; 80% of those determined to be eligible were enrolled and screened with ultrasound for fibroids ≥ 0.5 cm in diameter. African-American and white premenopausal participants who responded to at least one follow-up interview (N = 964, 85% of those eligible) constituted the study cohort. During follow-up (5822 person-years), participants self-reported any major uterine procedure (67% hysterectomies). Life-table analyses and Cox regression (with censoring for menopause) were used to estimate the risk of having a uterine procedure for women with no fibroids, small (women, importance of a clinical diagnosis of fibroids prior to study enrollment, and the impact of submucosal fibroids on risk were investigated. There was a greater loss to follow-up for African-Americans than whites (19 versus 11%). For those with follow-up data, 64% had fibroids at baseline, 33% of whom had had a prior diagnosis. Of those with fibroids, 27% had small fibroids (women during follow-up. The estimated risk of having a procedure in any given year of follow-up for those with fibroids compared with those without fibroids increased markedly with fibroid-size category (from 4-fold, confidence interval (CI) (1.4-11.1) for the small fibroids to 10-fold, CI (4.4-24.8) for the medium

    Three prospective randomised studies were conducted to compare pancreatoduodenectomy (PD) with duodenum-preserving pancreatic head resection (DPPHR) in patients suffering from chronic pancreatitis (cP). In these three series, the superiority of the duodenum-preserving technique with regard to quality of life (QOL) and pain relief has been demonstrated. Long-term follow-up investigations have not been published so far. The present paper reports on a 5-year follow-up study of a prospective, non-randomised trial comparing classic Whipple procedure (PD) with Beger DPPHR. Seventy patients were initially enrolled in this study. Fifty-one patients were left for the present long-term outcome analysis (PD, n = 24; DPPHR, n = 27). The follow-up included the following parameters: QOL, pain intensity, endocrine and exocrine function, and body mass index (BMI). The median follow-up was 63.5 (range 56-67) months. Two patients in the DPPHR group and none in the PD group underwent a re-operation. The QOL scores of the relevant symptom scales (nausea, pain, diarrhoea) and functional parameters (physical status, working ability, global QOL) were significantly better in the DPPHR group than in the PD group. Pain intensity as self-assessed by the patients was less pronounced in the DPPHR group (P Whipple procedure in terms of QOL and pain intensity as self-assessed by the patients.

    Full Text Available Background: Despite great reduction of in-stent restenosis, first-generation drug-eluting stents (DESs have increased the risk of late stent thrombosis due to delayed endothelialization. Arsenic trioxide, a natural substance that could inhibit cell proliferation and induce cell apoptosis, seems to be a promising surrogate of sirolimus to improve DES performance. This randomized controlled trial was to evaluate the efficacy and safety of a novel arsenic trioxide-eluting stent (AES, compared with traditional sirolimus-eluting stent (SES. Methods: Patients with symptoms of angina pectoris were enrolled and randomized to AES or SES group. The primary endpoint was target vessel failure (TVF, and the second endpoint includes rates of all-cause death, cardiac death or myocardial infarction, target lesion revascularization (TLR by telephone visit and late luminal loss (LLL at 9-month by angiographic follow-up. Results: From July 2007 to 2009, 212 patients were enrolled and randomized 1:1 to receive either AES or SES. At 2 years of follow-up, TVF rate was similar between AES and SES group (6.67% vs. 5.83%, P = 0.980. Frequency of all-cause death was significantly lower in AES group (0 vs. 4.85%, P = 0.028. There was no significant difference between AES and SES in frequency of TLR and in-stent restenosis, but greater in-stent LLL was observed for AES group (0.29 ± 0.52 mm vs. 0.10 ± 0.25 mm, P = 0.008. Conclusions: After 2 years of follow-up, AES demonstrated comparable efficacy and safety to SES for the treatment of de novo coronary artery lesions.

    Context: The crown lengthening procedure (CLP) is routinely carried out to correct gingival levels and achieve esthetic contours and adequate crown lengths for restorative purposes. Though the short-term outcomes have been found to be stable, long-term results are not much reported. Aims: To evaluate the long-term stability of the marginal bone levels, gingival levels, and the status of the teeth, which underwent endodontic therapy, followed by CLP and final restorations. Settings and Design: Institutional setting, long-term case series. Materials and Methods: Case records of the patients who underwent CLP and endodontic therapy for corrections of the supra-erupted teeth to regain the lost interocclusal spaces were retrieved, and the cases with complete set of the clinical and radiographs were taken. All the cases were recalled and bone levels on the radiographs, bleeding on probing, probing pocket depths, and changes in the soft tissue margins were evaluated. Statistical Analysis Used: Descriptive analysis. Results: A total of 25 teeth had undergone CLP and endodontic therapy and final restorations for a minimum of 24 months. The mean post-restorative duration was 50.8 ± 22.48 months (range 24–96 months). All the teeth were functional and asymptomatic with 100% survival. Interdental bone loss of 1 mm, probing pockets of 5 mm, and 1 mm buccal recession were observed in 16% of the sites. The amount of interocclusal space regained was adequate to restore the missing teeth in the opposing arch. Conclusions: The CLP is a predictive procedure for correction of supra-erupted teeth. The survival of the teeth that underwent the procedure in the present study was 100% over 24–96 months. PMID:27041850

    Revascularization aims at improving walking ability in patients with arterial claudication. The highest measured distance between 2 stops (highest-MDCW), the average walking speed (average-WSCW), and the average stop duration (average-DSCW) can be measured by global positioning system, but their evolution after revascularization is unknown.We included 251 peripheral artery diseased patients with self-reported limiting claudication. The patients performed a 1-hour stroll, recorded by a global positioning system receiver. Patients (n = 172) with confirmed limitation (highest-MDCW the follow-up period were compared with reference patients (ie, with unchanged lifestyle medical or surgical status). Other patients (lost to follow-up or treatment change) were excluded (n = 89).We studied 44 revascularized and 39 reference patients. Changes in highest-MDCW (+442 vs. +13 m) and average-WSCW (+0.3 vs. -0.2 km h) were greater in revascularized than in reference patients (both P the groups. Among the revascularized patients, 13 (29.5%) had a change in average-WSCW, but not in highest-MDCW, greater than the mean + 1 standard deviation of the change observed for reference patients.Revascularization may improve highest-MDCW and/or average-WSCW. This first report of changes in community walking ability in revascularized patients suggests that, beyond measuring walking distances, average-WSCW measurement is essential to monitor these changes. Applicability to other surgical populations remains to be evaluated. http://www.clinicaltrials.gov/ct2/show/NCT01141361.

    To assess patient-reported outcome measures (PROMs), aesthetics and stability of root coverage procedures from a previous 6-month RCT after 1 year. Forty-five patients (90 recessions) had received a coronally advanced flap (CAF = control) only or a xenogeneic collagen matrix in addition (CAF + CMX = test). Visual analogue scales (VAS) and questionnaires were used for PROMs and the root coverage aesthetic score (RES) for professional aesthetic evaluations. VAS scores (patient satisfaction) amounted to 8.58 ± 1.86 (test) versus 8.38 ± 2.46 (control). Six patients preferred CAF + CMX concerning surgical procedure and aesthetics, six preferred CAF and 29 were equally satisfied. RES was 7.85 ± 2.42 for the test group versus 7.34 ± 2.90 for the controls. Root coverage (RC) was 76.28% for test and 75.05% for control defects. The mean increase in keratinized tissue width was higher in test (from 1.97 to 3.02 mm) than in controls (from 2.00 to 2.64 mm) (p = 0.0413). Likewise, test sites showed more gain in gingival thickness (0.52 mm) than control sites (0.27 mm) (p = 0.0023). Compared to 6 months, clinical outcomes were stable. Results for PROMs, RES and RC did not significantly differ between treatment groups. Thickness and width of keratinized tissue were enhanced following CAF + CMX compared to CAF alone. © 2016 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

    Endovascular treatment (angioplasty with or without stenting) is an alternative to carotid endarterectomy for carotid artery stenosis but there are scarce long-term efficacy data showing that it prevents stroke. We therefore report the long-term results of the Carotid and Vertebral Artery Transluminal Angioplasty Study (CAVATAS).

    To investigate the effects and safety of gonadotropin releasing hormone analogue (GnRH-a) as an addition to progesterone luteal support in women who underwent in vitro fertilization/intracytoplasmic sperm injection-embryo transfer (IVF/ICSI-ET) and achieved a clinical pregnancy. A retrospective analysis was conducted on 214 patients who underwent IVF/ICSI-ET procedures with standard long mid-luteal protocol, of which 123 received GnRH-a-free protocol and 91 received GnRH-a-added protocol. The patients' pregnancy and delivery course, and their neonates' status at birth and growth/development after birth were statistically compared. There was no significant difference between both study groups regarding embryo risks and maternal complications during early pregnancy. as well as fetal risks during the middle and late stages and neonate risks during birth, except that the twin pregnancies of the GnRH-a-added group had a considerably greater male/female ratio, and a significantly higher rate of premature delivery and low birth weight than those of the GnRH-a-free group. In addition, there was no significant difference in neonate risks within 2 years after birth between both cohorts. With precautions taken to control the number of implanted embryos and reduce the incidence of twinning pregnancy, the addition of GnRH-a to luteal support is relatively safe and effective.

    A prospective study of 111 patients who underwent repeat coronary angiography and exercise thallium-201 scintigraphy 6 +/- 2 months after complete revascularization by percutaneous transluminal coronary angioplasty was performed to assess whether clinical, procedure-related and postangioplasty exercise variables yield independent information for the prediction of angiographic restenosis after angioplasty. Complete revascularization was defined as successful angioplasty of one or more vessels that resulted in no residual coronary lesion with greater than 50% diameter stenosis. Restenosis was defined as a residual stenosis at the time of repeat angiography of greater than 50% of luminal diameter. Restenosis occurred in 40% of the patients. The 111 patients were randomly subdivided into a learning group (n = 84) and a testing group (n = 27). A logistic discriminant analysis was performed in the learning group and the logistic model was used to estimate a logistic probability of restenosis. This probability of restenosis was validated in the testing group. In the learning group of 84 patients univariate analysis of 39 factors revealed 8 factors related to restenosis: recurrence of angina (p less than 0.0001), postangioplasty abnormal finding on exercise thallium-201 scintigram (p less than 0.0001), exercise thallium-201 scintigram score (p less than 0.0001), difference between exercise and rest ST segment depression (p less than 0.001), postangioplasty exercise ST segment depression (p less than 0.001), absolute postangioplasty stenosis diameter (p less than 0.003), postangioplasty exercise work load (p less than 0.03) and postangioplasty exercise heart rate (p less than 0.05)

    Full Text Available Many patients with rheumatoid arthritis (RA develop myocardial damage that is frequently latent and usually manifests itself as congestive heart failure and arrhythmias in the late period of the disease.Objective: to comparatively study the time course of clinical, structural, and functional changes in the myocardium in RA patients taking methotrexate (MTX and a combination of MTX and hydroxychloroquine (HC during a 4-year follow-up period.Subjects and methods. Clinical data and echocardiographic, carotid artery ultrasonographic, and Holter electrocardiogram (ECG monitoring readings were analyzed in 83 patients with RA with disease duration of < 10 years, who had received MTX (n = 44 or a combination of MTX and HC (n = 39 for 4 years. RA activity remained low (DAS28 ≤ 3.1 during the follow-up period.Results and discussion. Over 4 years, the RA patients showed significant increases in left ventricular mass index (from 106.20 [98.14; 112.44] to 114.23 [109.12; 131.19], in the rate of eccentric left ventricular hypertrophy (from 22.9 to 40.9%, frequent supraventricular extrasystoles (from 13.3 to 22.8%, different types of premature ventricular contractions (from 14.2 to 26.2%, paroxysmal ventricular tachycardia (from 1.2 to 3.6%, intraventricular conduction disturbances (from 3.6 to 14.4%, and first-degree atrioventricular block (from 2.4 to 4.8%, as well as atherosclerotic plaques in the carotid arteries (from 6.0 to 10.8% (p < 0.05. During combined therapy with MTX and HC, the increase in the rate of eccentric left ventricular hypertrophy, high-grade premature ventricular contractions, and right bundle-branch block was not so great as that during MTX monotherapy (5.1 and 29.6%; 5.1 and 18.2%; 2.6 and 11.4%, respectively.Conclusion. There is evidence that HC intake has a positive impact on myocardial structural and functional parameters in RA patients.

    To describe the role of magnetic resonance imaging (MRI) in establishing the indication for, planning, and following up uterine artery embolization (UAE) for treating symptomatic leiomyomas of the uterus on the basis of the current literature and our results. Retrospective analysis of the MRI findings obtained in 130 patients before and after UAE. Presentation of characteristic MRI features and their relevance in establishing the indication for, performing, and following up of UAE. Discussion of the results in conjunction with published data. The intermediate results of UAE reported in the literature show a successful improvement of leiomyoma-related symptoms in 82-94% of cases and an average reduction of leiomyoma size by 36-64%. The typical MRI appearance of degenerating leiomyomas is presented together with that of relevant differential diagnoses. MRI findings allow for establishing the indication for UAE by providing reliable information on the location, size, and number of uterine leiomyomas. Analysis of 60 patients of our study population showed solitary leiomyoma in 16% of cases, 2-10 leiomyomas in 47%, and over 10 in 37%. Subserosal, pedunculated leiomyomas cannot be treated by UAE; these were present in 5% of the patients. MR angiography is useful in assessing pelvic vascular anatomy before the intervention and identifies collateral vascular supply to the uterus. Contrast-enhanced imaging is suitable for monitoring successful devascularization following embolization and evaluating complications. (orig.)

    Purpose Endovascular ablation of the great saphenous vein has been proposed as a less invasive alternative to conventional ligation and stripping of varicose veins. Outcomes of patients treated with the radiofrequency ablation ClosureFast™ system over an eight-year period from a single-center were evaluated. Methods Three-year follow-up data included duplex ultrasound scan, complication rate, and questionnaires to assess patients' QOL, level of pain, and days off work. Results A total of 1080 consecutive patients (49.5 ± 18.6 years, 72% female, mean body mass index: 25.44 ± 4.1 kg m -2 ) underwent radiofrequency ablation for incompetent saphenous veins in a single institution. Occlusion of the great saphenous vein was obtained in 98.6% and 93.8% cases at the end of the procedures and within 36 months, respectively. Only three deep venous thromboses and minor complications occurred in this series throughout the first week from the procedure. A decrease of the external vein diameter, equal to 72.7% and 31.1% of the pretreatment diameter, was observed at 1 week and 36 months, respectively. The average Aberdeen Varicose Vein Questionnaire score improved from 18.06 ± 9.47 before treatment to 11.56 ± 10.23 at 12 months, with no significant differences in the subsequent follow-up. SF-36 QOL scores significantly improved after the procedure in all domains, while there were no changes over time. Patients reported a prompt return to normal daily activities (1.5 ± 0.7 days) and work (3.1 ± 1.9 days). Body mass index influenced QOL scores, while it did not affect great saphenous vein diameter reduction during the follow-up. On the contrary, Clinical Etiologic Anatomic Pathophysiologic class significantly influenced both great saphenous vein diameter reduction after the treatment and QOL scores within 36 months. Conclusion Results of this retrospective monocentric, large patients study suggest that radiofrequency ablation of the great

    The aim of this paper is to provide indications to choose what fraction of a self limiting stress can be considered as secondary. At first, considerations are given to a simple structure which could be called ''creep relaxation tensile test''. A bar (with constant cross section) is loaded by an elastic spring in order to obtain a given elongation of the assembly. The stress evolution is studied. Then the creep damage is computed, and compared to the damage corresponding to the elastic computed stress. This comparison gives the fraction of the self limiting stress which must be considered as primary. This involve the structural parameter 0 which is the initial value of the ratio of elastic energy to dissipating power. Extension of the rule is made with the help of KACHANOV approximation. As a conclusion a procedure is described which determines what fraction of a self limiting stress must be considered as primary

    George Hahalis, MD, PhD

    2016-07-01

    Full Text Available Despite the increasing worldwide adoption of the transradial access site, the ulnar artery (UA only very infrequently serves as a primary option for coronary procedures. In contrast to the uncertainty surrounding previous reports regarding the feasibility and safety, recent data from larger registries and randomized trials provide more conclusive evidence that the transulnar route may be safely selected as an alternative arterial access approach. However, a default transulnar strategy appears time-consuming and is associated with higher crossover rates compared with the radial artery (RA. Once arterial access is obtained, the likelihood of a successful coronary procedure is high and similar between the two forearm arteries. The UA has similar flow-mediating vasodilating properties with and seems at least as vulnerable as the RA with regard to incident occlusion, with UA occlusion (UAO rates being probably higher than previously anticipated. A learning curve effect may not be apparent for crossover rates among experienced radialists, but increasing experience is associated with reduction in the fluoroscopy time, contrast volume and frequency of large hematoma formation. The UA may represents an important alternative access site for coronary procedures, and experienced radial operators should obtain additional skills to perform the transulnar approach. Nevertheless, in view of this method's lower feasibility compared to the RA, an initial ulnar access strategy should be reserved for carefully selected patients to ensure satisfactory cannulation rates.

    Full Text Available The Article discuss the applicability of the follow-up system in purchase and logistics in a public organization. The study took place at the restaurant (R.U. of the State University of Londrina (UEL. After gathering information and relevant data and analyzing the results obtained, it was possible to verify that the follow-up system in the purchase procedure is informally used in that location, despite its importance. It could also be noticed that the university does not use the same system with the other units that integrate it. When comparing a public and a private company it is possible to conclude that the system used in a private company is more complete, as it is considered a routine procedure of the purchase department. As for the logistics system which integrates the purchase system, it was possible to verify that there are flaws in its conception and use, generating deviation and loss of resources used in the public sector. Some possible ways to solve the raised problems were pointed out, such as: the possibility of adopting the system of public concession in the same way that it is adopted in other public services in the city of LondrinaO artigo analisa a aplicabilidade do sistema de acompanhamento em compras e da logística numa organização pública. O local estudado foi o restaurante universitário (R.U. na Universidade Estadual de Londrina. Após terem sido colhidas as informações e os dados pertinentes, apresentados para o foco do problema e analisados os resultados obtidos, verificou-se que o sistema de acompanhamento em compras é utilizado informalmente no órgão especificado, apesar de sua importância, embora na universidade, não se adote o mesmo sistema para os órgãos que a integram. Na comparação feita entre uma empresa pública e a caracterização do sistema em uma empresa privada, verificou-se que o sistema utilizado na empresa privada é mais completo, como um procedimento rotineiro de serviço do departamento

    Appreciation and study of hepatic arterial anatomical variability is essential to the performance of a pancreaticoduodenectomy to avoid surgical complications such as bleeding, hepatic ischemia/failure, and anastomotic leak/stricture. Awareness of this variability permits the surgeon to adapt the surgical technique to deal with anomalies identified preoperatively or intraoperatively thereby preventing unnecessary surgical morbidity and mortality. The objective of our study is to provide a comprehensive review of the anatomic arterial anomalies and discuss surgical strategies that will equip the surgeon to deal with all anomalies that may be encountered a priori or en passant during the course of a Whipple procedure.

    Full Text Available OBJECTIVE: The purpose of this study was to improve the use of 64-channel multidetector computed tomography using lower doses of ionizing radiation during follow-up procedures in a series of patients with endovascular aortic aneurysm repair. METHODS: Thirty patients receiving 5 to 29 months of follow-up after endovascular aortic aneurysm repair were analyzed using a 64-channel multidetector computed tomography device by an exam that included pre-and postcontrast with both arterial and venous phases. Leak presence and type were classified based on the exam phase. RESULTS: Endoleaks were identified in 8/30 of cases; the endoleaks in 3/8 of these cases were not visible in the arterial phases of the exams. CONCLUSION: The authors conclude that multidetector computed tomography with pre-contrast and venous phases should be a part of the ongoing follow-up of patients undergoing endovascular aortic aneurysm repair. The arterial phase can be excluded when the aneurism is stable or regresses. These findings permit a lower radiation dose without jeopardizing the correct diagnosis of an endoleak.

    Purpose: Approximately 200,000 central venous catheterizations are carried out annually in the National Health Service in the United Kingdom. Inadvertent arterial puncture occurs in up to 3.7%. Significant morbidity and death has been reported. We report on our experience in the endovascular treatment of this iatrogenic complication. Methods: Retrospective analysis was carried out of 9 cases referred for endovascular treatment of inadvertent arterial puncture during central venous catheterization over a 5 year period. Results: It was not possible to obtain accurate figures on the numbers of central venous catheterizations carried out during the time period. Five patients were referred with carotid or subclavian pseudoaneurysms and hemothorax following inadvertent arterial catheter insertion and subsequent removal. These patients all underwent percutaneous balloon tamponade and/or stent-graft insertion. More recently 4 patients were referred with the catheter still in situ and were successfully treated with a percutaneous closure device. Conclusion: If inadvertent arterial catheterization during central venous access procedures is recognized and catheters removed, sequelae can be treated percutaneously. However, once the complication is recognized it is better to leave the catheter in situ and seal the artery percutaneously with a closure device

    This study aimed to evaluate the efficacy of low-level laser therapy (LLLT) and light-emitting diodes (LEDs) for reducing pain in hyperglycemic and normoglycemic patients who underwent coronary artery bypass surgery with internal mammary artery grafts. This study was conducted on 120 volunteers who underwent elective coronary artery bypass graft (CABG) surgery. The volunteers were randomly allocated to four different groups of equal size (n = 30): control, placebo, LLLT [λ = 640 nm and spatial average energy fluence (SAEF) = 1.06 J/cm(2)], and LED (λ = 660 ± 20 nm and SAEF = 0.24 J/cm(2)). Participants were also divided into hyperglycemic and normoglycemic subgroups, according to their fasting blood glucose test result before surgery. The outcome assessed was pain during coughing by a visual analog scale (VAS) and the McGill Pain Questionnaire. The patients were followed for 1 month after the surgery. The LLLT and LED groups showed a greater decrease in pain, with similar results, as indicated by both the VAS and the McGill questionnaire (p ≤ 0.05), on the 6th and 8th postoperative day compared with the placebo and control groups. The outcomes were also similar between hyperglycemic and normoglycemic patients. One month after the surgery, almost no individual reported pain during coughing. LLLT and LED had similar analgesic effects in hyperglycemic and normoglycemic patients, better than placebo and control groups.

    This paper conceptualises what sustainability assessment follow-up might entail for three models of sustainability assessment: EIA-driven integrated assessment, objectives-led integrated assessment and the contribution to sustainability model. The first two are characterised by proponent monitoring and evaluation of individual impacts and indicators while the latter takes a holistic view based around focused sustainability criteria relevant to the context. The implications of three sustainability challenges on follow-up are also examined: contested time horizons and value changes, trade-offs, and interdisciplinarity. We conclude that in order to meet these challenges some form of adaptive follow-up is necessary and that the contribution to sustainability approach is the best approach. -- Highlights: • We explore sustainability follow-up for three different sustainability models. • Long-time frames require adaptive follow-up and are a key follow-up challenge. • Other key challenges include interdisciplinarity, and trade-offs. • Sustainability follow-up should be a direction of travel and not an outcome. • Only the follow-up for contribution to sustainability model addresses sustainability challenges sufficiently.

    Peripheral arterial occlusive disease (PAD) includes acute and chronic disorders of the blood supply as a result of obstruction of blood flow in the arteries of the limb. Treatment of PAD can be conservative, surgical and endovascular. Percutaneous transluminal angioplasty with or without stenting has become a recognized method, which is increasingly used in treatment of arterial occlusive disease. This study aimed to determine early results of endovascular treatment of critical limb ischemia (CLI) patients with infrapopliteal lesions. The study included 69 patients (46 men; mean age 65 years, range 38-84) with CLI (class 4 to 6 according to Rutherford). The primary study endpoints were absence of major amputation of the target limb at 6 months and occurance of local and systemic complications specifically related to use of endovascular treatment. Major amputation was avoided in 61 patients. Through 6 months, 6 patients underwent additional revascularization. One local complication (clinicaly significant dissection of popliteal artery) occurred, and it was resolved by stent implantation. There were no cases of systemic complications and death during the follow-up period. Rates of major amputation were 12.3% for diabetics versus 8.3% for non-diabetics. Our data showed that endovascular treatment of infrapopliteal disease is an effective and safe treatment in patients experiencing CLI, provides high limb preservation and low complication rates. Study outcomes support endovascular treatment as a primary option for patients experiencing CLI due to below the knee (BTK) occlusive disease. © 2018 The Author(s).

    To evaluate the safety and efficacy of prophylactic uterine artery embolization (UAE) before obstetrical procedures with high risk for massive bleeding. A retrospective review of 29 female patients who underwent prophylactic UAE from June 2009 to February 2014 was performed. Indications for prophylactic UAE were as follows: dilatation and curettage (D and C) associated with ectopic pregnancy (cesarean scar pregnancy, n = 9; cervical pregnancy, n = 6), termination of pregnancy with abnormal placentation (placenta previa, n = 8), D and C for retained placenta with vascularity (n = 5), and D and C for suspected gestational trophoblastic disease (n = 1). Their medical records were reviewed to evaluate the safety and efficacy of UAE. All women received successful bilateral prophylactic UAE followed by D and C with preservation of the uterus. In all patients, UAE followed by obstetrical procedure prevented significant vaginal bleeding on gynecologic examination. There was no major complication related to UAE. Vaginal spotting continued for 3 months in three cases. Although oligomenorrhea continued for six months in one patient, normal menstruation resumed in all patients afterwards. During follow-up, four had subsequent successful natural pregnancies. Spontaneous abortion occurred in one of them during the first trimester. Prophylactic UAE before an obstetrical procedure in patients with high risk of bleeding or symptomatic bleeding may be a safe and effective way to manage or prevent serious bleeding, especially for women who wish to preserve their fertility

  1. Nonimaging aspects of follow-up in breast cancer reconstruction.

    Science.gov (United States)

    Wood, W C

    1991-09-01

    Follow-up of patients with breast cancer is directed to the early detection of recurrent or metastatic disease and the detection of new primary breast cancer. The survival benefit of early detection is limited to some patients with local failure or new primary tumors. That imaging is not used in follow-up of patients who have had breast cancer reconstruction is related to possible interference with this putative benefit by the reconstructive procedure. Such follow-up is accomplished by the patient's own surveillance, clinical examination, and laboratory testing supplemented by imaging studies. Clinical follow-up trials of women who have undergone breast reconstructive surgery show no evidence that locally recurrent breast carcinoma is masked when compared with follow-up of women who did not undergo reconstructive procedures. Reshaping of the contralateral breast to match the reconstructed breast introduces the possibility of interference with palpation as well as mammographic distortion in some women. This is an uncommon practical problem except when complicated by fat necrosis.

    A study of 31 patients operated on for rectal neoplasms between September, 1989 and September, 1995 in SantiAug de Cuba was performed. Patients Webre followed-up during this period for the purpose of the study. There was a frank predominance of males and ages between 45 and 64, of the stage II and the groups BI and BII according to Dukes' classification. Most patients received 5-fluoracil, without tumor relapses. The current survival rate of the series was 76 % at the end of the investigation. It is recommended that all patients operated on for this segment be followed-up after the operation; to continue with cytostatic treatment using 5-fluoracil, and to emphasize the importance of the use of tumor markers during the follow-up, in addition to transrectal ultrasound, as well as to make an early diagnosis through mass screening methods

    In recent years, the radial artery (RA) has become an alternative vascular access site for percutaneous coronary procedures, and the ulnar artery (UA) is another possibility. The objective of this study was to investigate the anatomy of the forearm arteries with ultrasound (US) and to evaluate the effect of the anatomy of the right RA (RRA) on the outcomes of transradial coronary procedures. The 638 patients undergoing transradial coronary procedures were examined with US for measurement of the diameters of the forearm arteries and determination of their anatomical abnormalities before the procedures. The next day the incidence of RA occlusion was recorded. The diameters of the radial and ulnar arteries were similar (P>0.05). The procedure time was longer in patients with anatomical abnormalities (Pforearm arteries of Chinese people are similar. The small diameter and anatomical abnormalities of the RRA could result in longer procedure time, more incidence of procedure failure and RA occlusion.

    Follow-up of obese patient is difficult. There is no literature related to patient follow-up that incorporates the concept of Internet of Things (IoT), use of WiFi, Internet, or portable devices for this purpose. This prospective observational study commenced in June 2011. Patients were prospectively offered to participate in the IoT study group, in which they received a WiFi scale (Withing®, Paris) that provides instant WiFi data to the patient and surgeon. Other patients were admitted to the standard follow-up group at the outpatient clinic. A total of 33 patients were included in our study (ten in the IoT group). Twelve patients did not have WiFi at home, ten lacked of computer knowledge, and seven preferred standard for follow-up. All patients underwent different surgical procedures. There were no complications. Excess weight loss (EWL) was similar in both groups. More than 90% of patients were satisfied. In the IoT group, patients considered it valuable in saving time, and considered seeing their evolution graphics extremely motivating. IoT technology can monitor medical parameters remotely and collect data. A WiFi scale can facilitate preoperative and follow-up. Standard follow-up in a classical outpatient clinic setting with the surgeon was preferred globally.

  8. Nuclear cardiology procedures to diagnose ischemia in coronary artery disease

    International Nuclear Information System (INIS)

    Kropp, J.

    1999-01-01

    Nuclear cardiology is equipped with a broad spectrum of diagnostic capabilities which allow the evaluation of ventricular performance, perfusion and metabolism of the heart. The principle of nuclear medicine procedures consists in the administration of free radioisotopes or radiopharmaceuticals to detect their spatial distribution within the body by detecting their y-rays from outside by gamma cameras. Myocardial perfusion scintigraphy is the most important procedure in nuclear cardiology and is performed on a routine basis with 201 Thallium-Chloride ( 201 Tl) since 1975. With the Single-Photon Emission Computerized Tomography (SPECT) technique it is possible to diagnose ischemia of the left ventricle on the basis of coronary artery disease with a sensitivity of 90-95% and a specificity of about 55%. Recently 99m Tc-tracers were developed for this purpose, which have many advantages due to their better physical properties, their easy handling and availability. The diagnostic accuracy is the same compared to ( 201 Tl). Free fatty acids labeled with 123 Iodine like 123 IPPA are alternative tracers to diagnose ischemia by the metabolic alteration and are pathognomonic tracers to diagnose the heart involvement in myopathies or metabolic defects related to fatty acid degradation which are the main fuel of the normal myocytes. Finally we should not forget the radionuclide ventriculography (RNVG) which is one of the oldest nuclear cardiology procedures providing us with very objective, reliable results of ventricular performance.

    Aim: To evaluate the efficacy and safety of renal artery embolisation (RAE) for renal arteriovenous malformation (AVM) as well as its outcomes. Materials and methods: The technical and clinical success rates, radiological and laboratory findings, and complications of RAE for 31 renal AVMs in 24 patients (M:F=9:15, mean age 46 years) at two separate medical institutions were retrospectively evaluated. Technical success was defined as complete occlusion of feeding arteries with no residual nidus seen on post-treatment angiography. Clinical failure was defined as recurrence of haematuria, presence of AVM on follow-up ultrasound or computed tomography, repeated RAE or surgery for the control of haematuria. Overall clinical success was defined as resolution haematuria or disappearance of AVM on follow-up imaging after single or multiple sessions of RAE. Results: Types of renal AVM were AVM, arterio-venous fistula (AVF) with intranidal aneurysm, and acquired AVF in 19, 1, and 4 patients, respectively. 18 patients (75%) underwent a single session of RAE, while 6 patients (25%) had two or more sessions of RAE. The level of embolisation was feeder, segmental artery, and main renal artery in 28 (90%), 2 (6%), and 1 (4%) procedures, respectively. Coil, n-butyl 2-cyanoacrylate, and polyvinyl alcohol were the most frequently chosen embolic materials and were used in 19, 14, and 8 procedures, respectively. The clinical success rate after initial RAE was 67% (16/24). Overall clinical success rate, including multisession RAE, was 88% (21/24). The technical success rate of 31 procedures was 65% (20/31). Among 11 technical failures in 10 patients, 4 achieved clinical success without additional RAE, 3 underwent second session RAE to achieve clinical success, and 3 patients underwent nephrectomy due to recurrence. Conclusion: RAE is a safe and effective treatment for renal AVM. Technical failure of RAE does not always lead to clinical failure and multiple embolisation sessions may be

    Purpose We compared outcomes of the U- and H-type approaches of the tension-free vaginal tape (TVT)-Secur procedure for the treatment of female stress urinary incontinence (SUI). Materials and Methods From March 2007 to July 2008, 115 women with SUI underwent TVT-Secur by a single surgeon. Patients were randomly assigned to either the U- or the H-type approach. After 12 months, postoperative changes in the Sandvik questionnaire, incontinence quality of life questionnaire (I-QoL), Bristol female lower urinary tract symptoms-scored form (BFLUTS-SF), and postoperative patient satisfaction were evaluated. Cure was regarded as no leakage on the Sandvik questionnaire. Complications were also evaluated. Results Of 115 women, 53 were treated with the U approach, and 62 women were treated with the H approach. At 12 months, 88.7% of those treated with the U approach and 87.1% of those treated with the H approach were cured (p=0.796). The I-QoL and filling, incontinence, sexual function, and QoL sum (BFLUTS-SF) scores were improved with both approaches, and there were no significant differences in the degree of improvement between approaches. Approximately 83.7% and 82.9% of the women treated with the U and H approaches, respectively, were satisfied with the outcome (p=0.858). There were 3 cases of intra-operative vaginal wall perforation in the H-type group. Immediate postoperative retention was observed in 2 women in the U-type group and 1 woman in the H-type group. One woman in the U-type group underwent tape releasing and cutting procedures for persistent large post-void residuals. Conclusions The U- and the H-type approaches of the TVT-Secur procedure provided comparable effectiveness for the treatment of female SUI. PMID:20428427

    Kawasaki disease (KD) is a systemic vasculitis that mainly affects coronary arteries in children, and requires regular follow-up from the time of diagnosis. To evaluate the feasibility of 64-slice CT angiography (CTA) for follow-up of patients with KD using previously performed invasive catheter coronary angiography (CCA) as reference standard. The study group comprised 12 patients (age 17.6 {+-} 2.9 years, mean{+-}SD) with a diagnosis of KD and a previously performed CCA (interval, 32.6 {+-} 13.5 months) who underwent 64-slice cardiac CTA. The quality of the images for establishing the presence of coronary abnormalities was determined by two observers. The CTA findings were compared with those from the prior CCA. Adequate image quality was obtained in all patients. Mean effective dose for CTA was 6.56 {+-} 0.95 mSv. CTA allowed accurate identification, characterization and measurement of all coronary aneurysms (n = 32), stenoses (n = 3) and occlusions (n = 9) previously demonstrated by CCA. One patient with disease progression went on to have percutaneous coronary intervention. Coronary lesions were reliably evaluated by 64-slice CTA in the follow-up of compliant patients with KD, reducing the need for repeated diagnostic invasive CCA. Hence, in an adequately selected patient population, the role of CCA could be limited almost only to therapeutic procedures. (orig.)

    Purpose: The purpose of this study was to evaluate the clinical long-term success of uterine artery embolization (UAE) in patients with symptomatic fibroids using spherical particles (Embosphere). Materials and Methods: 34 consecutive patients treated with UAE were initially enrolled in the study which had the following study goals (1) 1-year follow-up MRI evaluation of the fibroid behavior and (2) clinical long-term success due to standardized assessment of the main fibroid-related symptoms (hypermenorrhoea, dysmenorrhoea and dysuria) of the patients' individual overall health status and their therapy satisfaction at 1-year, 2- year and 3-year intervals after UAE. Results: Technical success was achieved in all procedures. Four patients had to be excluded from the long-term evaluation schedule: one because of a hysterectomy due to bleeding after 6 weeks, 3 patients were not available for the designated minimum follow-up interval. The preinterventional severe hypermenorrhoea (n = 27) with a score of 4.4 ± 0.7 (5 = extreme menstrual bleeding) decreased after one year to 2.1 ± 0.5 (p = 0.0001), after two years to 1.7 ± 0.5 (p = 0.0042) and after three years to 1.3 ± 0.6 (p = 0.0001). The preinterventional dysmenorrhoea (n = 15) with a score of 3.1 ± 1.5 (3 = distinctly increased dysmenorrhoea) decreased after one year to 1.1 ± 0.3 (p = 0.0001), after two years to 1.2 ± 0.2 and after three years to 1.2 ± 0.4 (p = 0.148). The pretreatment dysuria (n = 12) with a preinterventional score of 3.1 ± 1.5 (3 = distinctly increased dysuria) decreased after one year to 1.1 ± 0.3 (p 0.0069) and remained after two years at 1.1 ± 0.2 and after three years at 1.2 ± 0.4 (p = 0.905). The initial overall health status was 54.7 ± 20.1 (maximal value 100). After one year it rose to 90.5 ± 15.4 (p = 0.0001), was 91.8 ± 5.6 after two years and was 91.3 ± 8.5 (p = 0.8578) after three years. The satisfaction with the therapy was 2.9 ± 0.2 after one year, 2.6 ± 0.3 after two

    Full Text Available Background: Octogenarians account for a third of ischemic stroke (IS patients and they have higher morbidity and mortality rate among IS patients. The aim of this study was to evaluate the pri-procedural and long term clinical and angiographic statement of carotid artery angioplasty (CAA in octogenarians. Methods: In a mono-arm trial 102 patients>80 years old with symptomatic internal carotid artery (ICA stenosis presented by non-disabling IS or TIA underwent the CAA and were evaluated prospectively from January 2010 to July 2014. All patients had standard stroke care during the study follow up. The peri-procedural complications, cerebrovascular accidents, restenosis in target vessel and mortality rate were recorded to evaluate safety and durability of this secondary stroke prevention method in octogenarians. Results: 48 (47.06% males and 54 (52.9% females in a mean period of 24.5±14.1 (6-50 months were followed. For all patients mean age was 83.39 ±2.53 (range, 80-88 years. The success rate of CAA was 100%, whereas the peri-procedural complication rate was 5.8% (access-site local hematoma and bradycardia during CAA both in 2.94%.There was only one patient who had acute ischemic stroke during the procedure. Restenosis occurred in 3.9% after a mean of 21.5 months. The proportion of recurrent cerebrovascular accident was 9.8% while TIAs occurred in 3.9% and stroke in 1% of patients. Also 4.9% of patients experienced coronary artery disease and the proportion of fatal recurrent cerebrovascular accident was 2.9%.  The median patient event-free survival was 20 months. Conclusion: CAA seems to be a safe and durable IS secondary prevention method in octogenarians with symptomatic carotid artery stenosis.

    HLA-haploidentical family donors represent a valuable option for children requiring allogeneic hematopoietic stem cell transplantation (HSCT). Because graft-versus-host diseases (GVHD) is a major complication of HLA-haploidentical HSCT because of alloreactive T cells in the graft, different methods have been used for ex vivo T cell depletion. Removal of donor αβ T cells, the subset responsible for GVHD, and of B cells, responsible for post-transplantation lymphoproliferative disorders, have been recently developed for HLA-haploidentical HSCT. This manipulation preserves, in addition to CD34 +  progenitors, natural killer, γδ T, and monocytes/dendritic cells, contributing to anti-leukemia activity and protection against infections. We analyzed depletion efficiency and cell yield in 200 procedures performed in the last 3 years at our center. Donors underwent CD34 +   hematopoietic stem cell (HSC) peripheral blood mobilization with granulocyte colony-stimulating factor (G-CSF). Poor CD34 +  cell mobilizers (48 of 189, 25%) received plerixafor in addition to G-CSF. Aphereses containing a median of 52.5 × 10 9 nucleated cells and 494 × 10 6 CD34 +  HSC were manipulated using the CliniMACS device. In comparison to the initial product, αβ T cell depletion produced a median 4.1-log reduction (range, 3.1 to 5.5) and B cell depletion led to a median 3.4-log reduction (range, 2.0 to 4.7). Graft products contained a median of 18.5 × 10 6 CD34 +  HSC/kg recipient body weight, with median values of residual αβ T cells and B cells of 29 × 10 3 /kg and 33 × 10 3 /kg, respectively. Depletion efficiency monitored at 6-month intervals demonstrated steady performance, while improved recovery of CD34 +  cells was observed after the first year (P = .0005). These data indicate that αβ T cell and B cell depletion of HSC grafts from HLA-haploidentical donors was efficient and reproducible. Copyright © 2016 The American Society for Blood and Marrow

    Objective: To observe the clinical effect of the use of femoral artery hemostasis sticking V+PAD after the interventional procedure via femoral artery access. Methods: By using random permutation list 80 patients, who decided to receive coronary angiography and percutaneous transluminal coronary angioplasty, were randomly selected. Of the 80 patients, hemostasis sticking V + PAD was employed in 40 patients with even numbers (trial group), only manual compression was adopted to stop bleeding in another 40 patients with odd numbers (control group). All the patients were informed about this trial and had to sign a consent letter. The pressure time, the treatment method of access site after hemostasis, the posture in bed, the immobilization time, the comfort degree of patients, the complications of access site prior to discharge, etc. were observed and the results were compared between two groups. Results: There was no significant difference between two groups as respect to age, gender ratios,activated clotting time (ACT) value and blood pressure. However, significantly difference in the compression time and bed rest time existed between the two groups. The compression time in trial group and control group was (7.9 ± 0.5) min and (19.8 ± 5.1) min respectively (P<0.01), while the bed rest time in trial group and control group was (6.1 ± 5.0) hours and (23.9 ± 0.2) hours respectively (P<0.01). All patients in trial group was supine in bed with the head side of the bed raised at 30 degree immediately after the procedure, and the head side of the bed was further raised to 90 degree one hour later. The puncture site was bandaged with conventional compression and immobilization was not employed. Patients could lie in bed with free posture and the patient's comfort degree was greatly improved. During hospitalization no complications related to puncture site occurred in all patients except one obese woman in trial group who developed pseudoaneurysm. Conclusion: Femoral

    Spectroscopic follow-up observations play a crucial role in the confirmation and characterization of transiting planet candidates identified by Kepler. The most challenging part of this work is the determination of radial velocities with a precision approaching 1 m/s in order to derive masses from...... spectroscopic orbits. The most precious resource for this work is HIRES on Keck I, to be joined by HARPS-North on the William Herschel Telescope when that new spectrometer comes on line in two years. Because a large fraction of the planet candidates are in fact stellar systems involving eclipsing stars...... and not planets, our strategy is to start with reconnaissance spectroscopy using smaller telescopes, to sort out and reject as many of the false positives as possible before going to Keck. During the first Kepler observing season in 2009, more than 100 nights of telescope time were allocated for this work, using...

    To describe the laparoscopic approach for uretero-ileal anastomosis strictures and to analyse our long term series. A retrospective review was performed evaluating our series of patients with benign ureteroileal anastomosis strictures treated laparoscopically from 2011 to 2017. Demographics and perioperative data were obtained and analyzed. Complications were described with the Clavien-Dindo classification. The surgical technique was described and a literature review was performed. Eleven procedures were performed in ten patients. Mean blood loss was 180 ml. All the operations were performed laparoscopically without conversion. Mean hospital stay was 10 days (4-23). Early complications were Clavien-Dindo I y II: Two cases of limited anastomosis leakage, one lymphorrea, one paralitic ileum and one accidental descent of the ureteral catheter. Mean follow-up was 56 months (12-179) No late complications have been described. Based on our series with 5 year follow up, the laparoscopic approach for uretero-ileal anastomosis strictures is feasible and safe.

    Follow-up CT scans were taken from 12 cases of craniopharyngiomas after various treatment. Preoperative CT findings of craniopharyngiomas could be classified into three types. Type 1 was a non-enhanced or a thinly ring-like enhanced large cystic mass. Type 2 was a thickly enhanced large cystic mass with small solid mass. Type 3 was a large solid mass. Postoperative follow-up CT findings were as follows: Type 1 had a favorable postoperative course because the tumor tissues of the thin cystic wall seemed to collapse only with the procedure of cystic fluid aspiration. Recurrence frequently took place in patients of Type 2 and 3 if the tumor couldn't be radically removed or radiotherapy was not given after partial resection. Radiotherapy was most effective in these cases.

  1. From themes to hypotheses: following up with quantitative methods.

    Science.gov (United States)

    Morgan, David L

    2015-06-01

    One important category of mixed-methods research designs consists of quantitative studies that follow up on qualitative research. In this case, the themes that serve as the results from the qualitative methods generate hypotheses for testing through the quantitative methods. That process requires operationalization to translate the concepts from the qualitative themes into quantitative variables. This article illustrates these procedures with examples that range from simple operationalization to the evaluation of complex models. It concludes with an argument for not only following up qualitative work with quantitative studies but also the reverse, and doing so by going beyond integrating methods within single projects to include broader mutual attention from qualitative and quantitative researchers who work in the same field. © The Author(s) 2015.

    1990-10-01

    Full Text Available Pneumatic dilatation is one of the more recent methods in the management of achalasia cardia. Fifty dilatations were done in 42 patients with achalasia cardia over 5 years. There was a significant decrease in the maximum diameter of the oesophagus and a significant increase in diameter in the narrowed lower oesophageal segment in all the patients. Of the patients studied, 95.23% were relieved of their symptoms after only one to two sessions. There were no immediate complications. Out of the 38 patients on long term follow up, 8 (21.05% had recurrence of symptoms. On repeat dilatations, 4 (50% of them had good response. Late complication like reflux oesophagitis was observed in only 1 patient over a median follow up period of 22 months. It was thus concluded that pneumatic dilatation is a safe, simple and effective procedure in managing patients with achalasia cardia.

    The externally supported Ross (supported Ross), consisting of a Dacron (DuPont, Wilmington, DE) graft to support the neoaortic root, has been used in adolescent and adult patients to prevent neoaortic dilatation. Outcomes after the supported Ross technique were compared with the Ross procedure using the standard aortic root replacement technique (standard Ross). This was a retrospective analysis of 36 adolescent and young adult patients who underwent the Ross procedure between 1992 and 2013. The outcomes of supported Ross procedures in 26 patients were compared with the Ross procedure in 10 patients. End points included survival, neoaortic root dilatation, development of neoaortic regurgitation, and the need for reintervention. The median age at operation was 14 years (range, 11 to 31 years), and indications for the operation were mixed lesions (47%), followed by aortic regurgitation (42%) and stenosis (11%). There were no early deaths. The mean follow-up was 2.2 years (range, 1 to 11 years). At the 1-year (p = 0.01) and 3-year (p Ross cohort had a smaller neoaortic root z-score. Neither cohort had a large number of patients with significant neoaortic regurgitation, with 1 patient in the supported cohort compared with 3 patients in the standard cohort. Overall, 4 patients (40%) in the standard Ross cohort had required reintervention, including 3 directed at the neoaortic root. One patient in the supported Ross cohort required early reintervention for revision of the right coronary artery. At intermediate follow-up, patients who underwent the supported Ross technique were less likely to have neoaortic root dilatation compared with patients who underwent a standard Ross procedure. Further studies are needed to evaluate the long-term durability of this technique, particularly in regards to the development of significant aortic regurgitation, the rate of reintervention, and application to younger and smaller patients.

    The report reviews the available sources of data within Canada for undertaking morbidity follow-up studies to both supplement and complement studies using Canadian mortality data. Such studies would permit earlier detection and more sensitive measures of differences in risk for exposures to radiation and allow timely measures to be taken to minimize any occupational and environmental health risk to radiation workers. The technical feasibility of using these sources was reviewed using the criteria of adequate personal identifying information, automation of data records, file size and the accuracy of the morbidity diagnosis information. At the present time certain of the provincial cancer registry files meet these criteria best. A work plan was prepared suggesting a morbidity pilot study to clarify the role of occupational factors in the incidence of cancer among radiation workers using the Alberta Cancer Registry file and the National Dose Registry (NDR) file of radiation workers. For the longer term a full cohort study using the National Cancer Incidence Reporting System (NCIRS) and the NDR workers as the study population would provide information on all radiation workers on a national basis. A work plan was prepared and some initial format conversion of historical data was undertaken to begin developing the NCIRS into a data base suitable for long-term health studies

    To determine the long-range psychological effects of therapeutic abortion, 50 women (aged from 13-44 years), who were granted abortions between 1967 and 1968 Because of possible impairment of mental and/or physical health, were analyzed by use of demographic questionnaires, psychological tests, and interviews. Testing revealed that 44 women had psychiatric problems at time of abortion. 43 patients were followed for 3-6 months. The follow-up interviews revealed that 29 patients reacted positively after abortion, 10 reported no significant change and 4 reacted negatively. 37 would definitely repeat the abortion. Women under 21 years of age felt substantially more ambivalent and guilty than older patients. A study of 36 paired pre- and post-abortion profiles showed that 15 initially abnormal tests had become normal. There was a significant increase in contraceptive use among the patients after the abortion, but 4 again became pregnant and 8 were apparently without consistent contraception. It is concluded that the abortions were therapeutic, but physicians are encouraged to be aware of psychological problems in abortion cases. Strong psychological and contraceptive counselling should be exercised.

    A longitudinal and prospective study of 69 patients operated on for colon cancer was carried out during 6 years. Patients Webre folloWebd-up for the purpose of the study. The analysis evidenced that the most frequent age group ranged betWeben 65 and 74 years and that there was a predominance of females, as Webll as of stages II and III b and groups BI and BII according to Dukes' classification. Certain relapses resulting in re operations Webre detected. 5-fluoracil was used as a therapeutic agent, while the highest survival rate was attained in patients presenting with tumors in 0, I, II, and III a stages from groups A, BI, and CI of Dukes, or in those who complied with the cytostatic treatment. Survival outcomes Webre higher than the ones reported. Recommendations include to encourage mass screening in those risk groups at primary care level in order to detect early the entity, and thus improve the surgical outcomes and the results of postoperative follow-up

    The political approvals have been given for the return of Bikini and Enewetak Atolls to their original inhabitants. These two regions, which comprised the Pacific Nuclear Testing Areas from 1946 to 1958, are now being repopulated by their original inhabitants and their families. Recent assessments of internal and external exposure pathways at Bikini and Enewetak have indicated that doses and dose commitments in excess of current radiation protection guidelines are possible or even likely for persons living in these areas. Rongelap and Utirik Atolls, which were downwind of the 1954 Bravo event, also received significant fallout; potential radiological problems exist in these areas as well. In view of this prospect, follow-up environmental monitoring and personnel monitoring programs are being established to maintain our cognizance of radiological conditions, and to make corrective action where necessary. The unexpected finding of detectable amounts (above background) of plutonium in the urine of individuals at Bikini and Rongelap Atolls also raises the possibility of radiological problems in the long term from environmentally-derived plutonium via pathways which are not completely understood. This finding adds further impetus to the surveillance programs for an area where real radiological concerns for the general public are already known to exist. The continuing environmental and personnel monitoring programs which this paper describes are a necessary part of the BNL radiological safety program in the Marshall Islands, which is designed to do the following: (1) elucidate the internal exposure pathways; (2) define the external radiation environment; (3) assess the doses and dose commitments from radioactivity in the environment; (4) provide the feedback necessary to improve existing predictive modelling of radiological trends; and (5) suggest actions which will minimize doses via the more significant pathways.

    Aberrant hepatic arterial anatomy poses a challenge for the surgeon during Whipple procedure. Intraoperative injury to the aberrant vasculature results in hemorrhagic or ischemic complications involving the liver and biliary tree. We report a case of replaced right hepatic artery arising from the superior mesenteric artery in a patient with periampullary carcinoma of the pancreas, undergoing pancreaticoduodenectomy. The aberrant artery was found to be coursing through the pancreatic parenchyma. This is a rare vascular anomaly. Resection of the arterial segment and end-to-end anastomosis was fashioned. Intrapancreatic course of the replaced right hepatic artery is a rare anomaly and is best managed by preoperative identification on radiology and meticulous intra-operative dissection and preservation. However, for an intrapancreatic course, resection and reconstruction may occasionally be required.

    Full Text Available Background: Primary cemented total hip arthroplasty is a procedure for non-traumatic and traumatic affections of the hip. Long term follow-up is required to assess the longevity of the implant and establish the procedure. Indo-Asian literature on long term result of total hip arthroplasty is sparse. We present a 10-year follow-up of our patients of primary cemented total hip arthroplasty. Materials and Methods: We operated 31 hips in 30 patients with primary cemented total hip arthroplasty. We followed the cases for a minimum period of 10 years with a mean follow-up period of 12.7 years. The mean age of the patients was 60.7 years (range 37-82 yrs male to female ratio was 2:1. The clinical diagnoses included - avascular necrosis of femoral head (n=15, sero positive rheumatoid arthritis (n=5, seronegative spondylo-arthropathy (n=4, neglected femoral neck fractures (n=3, healed tubercular arthritis (n=2 and post traumatic osteoarthritis of hip (n=2. The prostheses used were cemented Charnley′s total hip (n=12 and cemented modular prosthesis (n=19. The results were assessed according to Harris hip score and radiographs taken at yearly intervals. Results: The mean follow-up is 12.7 yrs (range 11-16 yrs Results in all operated patients showed marked improvement in Harris hip score from preoperative mean 29.2 to 79.9 at 10 years or more followup. However, the non-inflammatory group showed more sustained long term improvement as compared to the inflammatory group, as revealed by the Harris hip score. Mean blood loss was 450ml (±3.7 ml, mean transfusion rate was 1.2 units (±.3. The complications were hypotension (n=7, shortening> 1.5 cm (n=9, superficial infection (n=2 and malposition of prosthesis (n=1. Conclusion: The needs of Indian Asian patients, vary from what is discussed in literature. The pain tolerance is greater than western population and financial constraints are high. Thus revision surgery among Indian-Asian patients is less compared

    One of the commonest forms of orthotopic bladder substitution for bladder cancer surivors, used in our institute, is the use of ileocecal segment. Sometimes, the need for Indiana pouch heterotropic continent diversion arises. Aim: To compare the long-term effect of orthotopic ileocecal bladder and heterotropic Indiana pouch following radical cystectomy in bladder cancer patients. Patients and methods: Between January 2008 and December 2011, 91 patients underwent radical cystectomy/anterior pelvic exentration and ortho topic ileocecal bladder reconstruction (61 patients) and Indiana pouch (30 patients), when orthotopic diversion could not be technically or oncologically feasible. Results: Convalescence was uneventful in most patients. All minor and major urinary leakage cases, in both diversions groups, where successfully conservatively treated. Only one patient in the ileocecal group with major urinary leak required re-exploration with successful revision of uretro-colonic anastomosis. Only one patient in the Indiana pouch group had accidentally discovered sub-centimetric stone, which was simply expelled. The overall survival proportion of ileocecal group was 100% compared to 80% in the Indiana pouch group (p < 0.001). The disease free survival proportion of ileocecal group was 90.8% compared to 80% in the Indiana pouch group (p = 0.076). Effective comparative daytime and nighttime urinary continence as well as renal function deterioration were not statistically significant between both reconstruction types. Conclusion: Both ileocecal bladder and Indiana pouch are safe procedures in regard to long-term effects over kidney function following radical cystectomy

    The uptake of percutaneous coronary procedures via the radial artery has increased internationally due to the decreased risk of complications and increased patient satisfaction. The increased susceptibility of the radial artery to spasm however presents a potential risk for procedural failure. Although most experts agree on the need for prophylactic medications to reduce radial artery spasm, currently there is inconsistency in literature regarding the most effective vasodilatory medication or combination of medications. The objective of this study is to identify the effectiveness of vasodilatory medications on radial artery spasm in patients undergoing transradial coronary artery procedures. This review considered studies that included participants aged 18 years and over undergoing non-emergent transradial percutaneous coronary artery procedures. This review considered studies that used vasodilating intravenous and intra-arterial medications or combinations of medications prior to commencing and during transradial coronary approaches to reduce radial artery spasm. The outcomes of interest were the incidence of radial artery spasm during percutaneous coronary procedure using objective and/or subjective measures and its effect on the successful completion of the procedure. Randomized controlled trials published in the English language between 1989 to date were considered for inclusion. The search strategy aimed to find both published and unpublished studies. A three-step search strategy was utilized in this review. An initial search of MEDLINE, CINAHL and Scopus was undertaken, followed by a search for unpublished studies. Papers selected for retrieval were assessed by two independent reviewers for methodological validity prior to inclusion in the review using standardized critical appraisal instruments. Any disagreements that arose between the reviewers were resolved through discussion. Quantitative data was extracted from papers included in the review using the

    To investigate the incidence, predisposing factors and image features of iatrogenically induced focal parenchymal changes in the lateral segment of the liver after a pancreatoduodenectomy. A follow up CT taken on the seventh day after an uneventful pancreatoduodenectomy were retrospectively reviewed for 123 patients for newly developed focal hepatic lesions. The location, size, and shape of the lesions were analyzed along with preoperative anatomic variation of the hepatic artery, for the degree of intrahepatic bile duct dilatation and procedure duration. Other than two patients with hepatic metastases, 13 (10.6%) patients showed newly developed irregular (n = 9), linear (n = 2) or wedge like (n = 2) hypovascular areas (1.4-8.5 cm; mean, 2.8 cm) in the posterior subcapsular portion of the lateral segment. There were only two patients (15.4%) with an aberrant origin of the segmental hepatic artery from the left gastric artery, and the degree of bile duct dilatation was nonspecific for the 13 subjected patients. Mean procedure time was not significantly different between the subjected patients and the others (541 min vs. 507 min; p = 0.160). Focal iatrogenic injury in the lateral segment after a pancreatoduodenectomy would not be a common event regardless of preoperative vascular anatomic variation, bile duct dilatation, or procedure duration.

    Since the birth of the first baby conceived by in vitro fertilization (IVF) 30 years ago (Louise Brown in 1978), there has been a rapid and constant increase in the number of couples using assisted reproductive technologies (ART). Around four million of children have been born from couples experiencing fertility problems, through the use of ART, comprising roughly 2-3 % of all births in Europe and U.S. That highlights that these modes of fertilization are now well assumed by our societies. However, several questions on health of these children remain to be elucidated. As evoked in this review, even if methodological limitations exist, numerous studies have reported increased risks of birth defects, like prematurity, foetal hypotrophy, neonatal complications, congenital malformations and epigenetic diseases among ART-conceived children as compared to naturally conceived children. Nowadays, it is difficult to determine if these increased risks found in ART infants are a consequence of the ART procedures or are inherent to the infertility problems per se. However, absolute risks remain moderate and reassuring as well as the data on follow-up into infancy and early childhood. Nevertheless, because the effects may occur at the adulthood, there is a need for long-term follow-up of children born after ART. Copyright © 2013 Elsevier Masson SAS. All rights reserved.

    In April and May 2007 the Regional HEP Team (RHT) conducted a follow-up HEP analysis on the Egger (612 acres) and Herzog (210 acres) parcels located at the north end of the Shillapoo Wildlife Area. The Egger and Herzog parcels have been managed with Bonneville Power Administration funds since acquired in 1998 and 2001 respectively. Slightly more than 936 habitat units (936.47) or 1.14 HUs per acre was generated as an outcome of the 2007 follow-up HEP surveys. Results included 1.65 black-capped chickadee HUs, 280.57 great blue heron HUs, 581.45 Canada goose HUs, 40 mallard HUs, and 32.80 mink HUs. Introduction A follow-up Habitat Evaluation Procedures (HEP) (USFWS 1980) analysis was conducted by the Columbia Basin Fish and Wildlife Authority's (CBFWA) Regional HEP Team (RHT) during April and May 2007 to document changes in habitat quality and to determine the number of habitat units (HUs) to credit Bonneville Power Administration (BPA) for providing operation and maintenance (O&M) funds since WDFW acquired the parcels. The 2007 follow-up HEP evaluation was limited to Shillapoo Wildlife Area (SWA) parcels purchased with Bonneville Power Administration funds. D. Budd (pers. comm.) reported WDFW purchased the 612 acre Egger Farms parcel on November 2, 1998 for $1,737,0001 and the 210 acre Herzog acquisition on June 21, 2001 for $500,000 with Memorandum of Agreement funds (BPA and WDFW 1996) as partial fulfillment of BPA's wildlife mitigation obligation for construction of Bonneville and John Day Dams (Rasmussen and Wright 1989). Anticipating the eventual acquisition of the Egger and Herzog properties, WDFW conducted HEP surveys on these lands in 1994 to determine the potential number of habitat units to be credited to BPA. As a result, HEP surveys and habitat unit calculations were completed as much as seven years prior to acquiring the sites. The term 'Shillapoo Wildlife Area' will be used to describe only the Herzog and Egger parcels in this

    To determine the costs associated with the diagnostic work-up and percutaneous revascularization of renal artery stenosis from various perspectives. A prospective multicenter comparative study was conducted between 1998 and 2001. A total of 402 hypertensive patients with suspected renal artery stenosis were included. Costs were assessed of computed tomography angiography (CTA), magnetic resonance angiography (MRA), digital subtraction angiography (DSA), and percutaneous revascularization. From the societal perspective, DSA was the most costly (EUR 1,721) and CTA the least costly diagnostic technique (EUR 424). CTA was the least costly imaging procedure irrespective of the perspective used. The societal costs associated with percutaneous renal artery revascularization ranged from EUR 2,680 to EUR 6,172. Overall the radiology department incurred the largest proportion of the total societal costs. For the management of renal artery stenosis, performing the analysis from different perspectives leads to the same conclusion concerning the least costly diagnostic imaging and revascularization procedure.

    The strain on clinic and surgeon resources resulting from a rise in demand for total knee replacement (TKR) requires reconsideration of when and how often patients need to be seen for follow-up. Surgeons will otherwise require increased paramedical staff or need to limit the number of TKRs they undertake. We reviewed the outcome data of 16 414 primary TKRs undertaken at our centre to determine the time to re-operation for any reason and for specific failure mechanisms. Peak risk years for failure were determined by comparing the conditional probability of failure, the number of failures divided by the total number of TKRs cases, for each year. The median times to failure for the most common failure mechanisms were 4.9 years (interquartile range (IQR) 1.7 to 10.7) for femoral and tibial loosening, 1.9 years (IQR 0.8 to 3.9) for infection, 3.1 years (IQR 1.6 to 5.5) for tibial collapse and 5.6 years (IQR 3.4 to 9.3) for instability. The median time to failure for all revisions was 3.3 years (IQR 1.2 to 8.5), with an overall revision rate of 1.7% (n = 282). Results from our patient population suggest that patients be seen for follow-up at six months, one year, three years, eight years, 12 years, and every five years thereafter. Patients with higher pain in the early post-operative period or high body mass index (≥ 41 kg/m(2)) should be monitored more closely.

    Objective: To evaluate the middle-long term efficacy of intracranial aneurysms with Guglielmi detachable Coil (GDC) embolization. Methods: 131 cases with 134 aneurysms were embolized with GDC. Of them, 39 aneurysms were in the anterior communication artery, 45 in the posterior communication artery, 19 in the siphon segment of internal carotid artery, 14 in the mediate cerebral artery, 3 in the anterior cerebral artery, 9 in the posterior circle and 5 in other. A wide-neck (neck > 4 mm, or aneurysm body/neck 2 = 8.643, P < 0.01. Follow-up DSA showed no change in 118 aneurysms which were a total or nearly total occlusion on post-embolization DSA. In 16 aneurysms with subtotal or partial occlusion, re-open of aneurysm showed in 9 cases, reduced in 3, no change in 4 on follow-up DSA. Conclusion: Although the recent-medium-term efficacy of intracranial aneurysms with GDC embolization is in the affirmative, a period follow-up DSA is essential, especially in aneurysms with subtotal or partial occlusion. Again, re-embolization with GDC is recommended in a re-open aneurysm

    Purpose. To investigate the long-term outcome and efficacy of emergency treatment of acute aortic diseases with endovascular stent-grafts. Methods. From September 1995 to April 2007, 37 patients (21 men, 16 women; age 53.9 ± 19.2 years, range 18-85 years) with acute complications of diseases of the descending thoracic aorta were treated by endovascular stent-grafts: traumatic aortic ruptures (n = 9), aortobronchial fistulas due to penetrating ulcer or hematothorax (n = 6), acute type B dissections with aortic wall hematoma, penetration, or ischemia (n = 13), and symptomatic aneurysm of the thoracic aorta (n = 9) with pain, penetration, or rupture. Diagnosis was confirmed by contrast-enhanced CT. Multiplanar reformations were used for measurement of the landing zones of the stent-grafts. Stent-grafts were inserted via femoral or iliac cut-down. Two procedures required aortofemoral bypass grafting prior to stent-grafting due to extensive arteriosclerotic stenosis of the iliac arteries. In this case the bypass graft was used for introduction of the stent-graft. Results. A total of 46 stent-grafts were implanted: Vanguard/Stentor (n = 4), Talent (n = 31), and Valiant (n = 11). Stent-graft extension was necessary in 7 cases. In 3 cases primary graft extension was done during the initial procedure (in 1 case due to distal migration of the graft during stent release, in 2 cases due to the total length of the aortic aneurysm). In 4 cases secondary graft extensions were performed-for new aortic ulcers at the proximal stent struts (after 5 days) and distal to the graft (after 8 months) and recurrent aortobronchial fistulas 5 months and 9 years after the initial procedure-resulting in a total of 41 endovascular procedures. The 30-day mortality rate was 8% (3 of 37) and the overall follow-up was 29.9 ± 36.6 months (range 0-139 months). All patients with traumatic ruptures demonstrated an immediate sealing of bleeding. Patients with aortobronchial fistulas also demonstrated a

    We wanted to evaluate the mural changes by CT on the follow-up examination of patients with active Takayasu arteritis. The study included 18 patients, (4 males and 14 females), with active Takayasu arteritis. A total of 44 CT examinations were done during the follow-up period (mean: 55.6 months). At the time of the last follow-up CT, the disease, on the basis of the erythrocyte sedimentation rate (ESR), was found to be inactive in five patients and the disease was active and persistent in 13 patients. The thickness and CT attenuation of the aortic wall on the precontrast, arterial and venous phases were measured on the initial and the follow-up CT examinations. The ratio of the mural attenuation over that of the back muscle on the initial CT was compared with the ratio found on the follow-up CT. The initial CT findings included high density and calcifications of the aortic wall in the precontrast images and a thickened wall with enhancements in the arterial and the venous phases. A low-attenuation ring was demonstrated in the venous phase in 15 patients (83%). On the follow-up evaluation, the mean mural thickness decreased significantly from 4.1 mm to 2.4 mm. The mean mural attenuation ratio in the venous phase decreased significantly from 1.9 to 1.3 (p 0.001). The low attenuation ring was identified in seven patients (39%) who had only with active, persistent Takayasu arteritis. The mural changes demonstrated by the follow-up CT evaluations for the patients with active Takayasu arteritis included a decrease of the mural thickness and enhancement, disappearance of the low-attenuation ring on the venous phase, and an increase of the mural attenuation and calcification on the precontrast phase

    2006-01-01

    Objectives To examine by retrospective analysis of data from the FLEXI‐CUT monocentre registry whether atherectomy can effectively simplify complex stent implantation in ostial bifurcation lesions by reducing the procedure to stenting of the left anterior descending (LAD) or left circumflex (LCX) artery ostium alone. Patients and methods All patients who had been enrolled in the prospective FLEXI‐CUT study (directional atherectomy with adjunctive balloon angioplasty) were retrospectively analysed on the basis of significant LAD or LCX ostial stenosis (⩾ 70% stenosis) deriving from an undiseased left main stem. The primary combined end point was the rate of target lesion revascularisation (TLR) and binary restenosis; secondary end points were procedural success and major adverse cardiac events (MACE) at the six‐month follow up. Results Of 30 patients enrolled with significant LAD or LCX ostium stenosis, 29 were effectively treated with directional atherectomy (96.7% procedural success). All patients underwent single‐vessel stenting procedures of solely the LAD or LCX ostium. At follow up, binary stenosis was 25% (6 of 24), TLR (angiographic plus clinical) 10.3% (3 of 29) and total MACE 6.9% (2 of 29). Conclusions Directional atherectomy with single‐vessel stenting procedures facilitates the interventional treatment of LAD and LCX ostium stenosis, and leads to remarkably low TLR and binary stenosis at follow up.

    A 23-year-old male patient with right nasal Juvenile Nasopharyngeal Angiofibroma (JNA) developed Central Retinal Artery Occlusion (CRAO) during embolization of the tumor using polyvinyl alcohol particles before endoscopic excision. Classic CRAO management was initiated by an ophthalmologist after 12 h. Retrospective evaluation of the angiograms revealed a tiny communication between the external carotid and ophthalmic arteries which had not been noticed before embolization. During endoscopic excision, the tumor was found to originate extraordinarily from midline structures. It was concluded that CRAO might be a rare complication of JNA embolization. Careful preoperative angiographic evaluations to detect communicating arteries and immediate ophthalmologic consultation in case of developing visual symptoms during the procedure are necessary.

    Full Text Available The follow-up time was investigated. The aim of this analysis was to create a formula that allows the follow-up time calculated using the most important external parameters. The studies were based on empirical data collected at small roundabouts localized on Upper Silesia. The follow-up time is the average time gap between two cars of the minor stream being queued and entered the same major stream gap one behind the other. Follow-up times were measured directly by observing traffic flow. Resulting follow-up times were analyzed to determine their dependence on parameters such as intersection layout, roundabouts diameter and left visibility. These parameters were tested using the conventional calculation method (regression analysis. The dependence of follow-up time was then integrated into the own capacity estimation method for small roundabouts localized on urban areas. One of the biggest advantages this dependence is that capacity and traffic flow on small roundabouts can be determined reliably and appropriately for actual situations. The new follow-up time values for all range of external diameters of small roundabout 26 (22 – 40 m have been presented in this article.

  11. There is no benefit to universal carotid artery duplex screening before a major cardiac surgical procedure.

    2014-01-01

    Perioperative stroke is a devastating complication after cardiac surgery. In an attempt to minimize this complication, many cardiac surgeons routinely preoperatively order carotid artery duplex scans to assess for significant carotid stenosis. We hypothesize that the routine screening of preoperative cardiac surgery patients with carotid artery duplex scans detects few patients who would benefit from carotid intervention or that a significant carotid stenosis reliably predicts stroke risk after cardiac surgery. A retrospective review identified 1,499 patients who underwent cardiac surgical procedures between July 1999 and September 2010. Data collected included patient demographics, comorbidities, history of previous stroke, preoperative carotid artery duplex scan results, location of postoperative stroke, and details of carotid endarterectomy (CEA) procedures before, in conjunction with, or after cardiac surgery. Statistical methods included univariate analysis and Fisher's exact test. Twenty-six perioperative strokes were identified (1.7%). In the 21 postoperative stroke patients for whom there is complete carotid artery duplex scan data, 3 patients had a hemodynamically significant lesion (>70%) and 1 patient underwent unilateral carotid CEA for bilateral disease. Postoperative strokes occurred in the anterior cerebral circulation (69.2%), posterior cerebral circulation (15.4%), or both (15.4%). Patient comorbidities, preoperative carotid artery duplex scan screening velocities, or types of cardiac surgical procedure were not predictive for stroke. Thirteen patients (0.86%) underwent CEA before, in conjunction with, or after cardiac surgery. Two of these patients had symptomatic disease, 1 of whom underwent CEA before and the other after his cardiac surgery. Of the 11 asymptomatic patients, 2 underwent CEA before, 3 concurrently, and 6 after cardiac surgery. Left main disease (≥50% stenosis), previous stroke, and peripheral vascular disease were found to be

    Controversy exists whether follow-up after resection of pancreatic ductal adenocarcinoma (PDAC) should include standardized imaging for the detection of disease recurrence. The purpose of this study was to evaluate how often patients undergo imaging in a setting where routine imaging is not performed. Secondly, the pattern, timing, and treatment of recurrent PDAC were assessed. This was a post hoc analysis of a prospective database of all consecutive patients undergoing pancreatic resection of PDAC between January 2011 and January 2015. Data on imaging procedures during follow-up, recurrence location, and treatment for recurrence were extracted and analyzed. Associations between clinical characteristics and post-recurrence survival were assessed with the log-rank test and Cox univariable and multivariable proportional hazards models. A total of 85 patients were included. Seventy-four patients (87%) underwent imaging procedures during follow-up at least once, with a mean amount of 3.1 ± 1.9 imaging procedures during the entire follow-up period. Sixty-eight patients (80%) were diagnosed with recurrence, 58 (85%) of whom after the manifestation of clinical symptoms. Additional tumor-specific treatment was administered in 17 of 68 patients (25%) with recurrence. Patients with isolated local recurrence, treatment after recurrence, and a recurrence-free survival >10 mo had longer post-recurrence survival. Even though a symptomatic follow-up strategy does not include routine imaging, the majority of patients with resected PDAC underwent additional imaging procedures during their follow-up period. Further prospective studies are needed to determine the actual clinical value, psychosocial implications, and cost-effectiveness of different forms of follow-up after resection of PDAC.

    Full Text Available Background: The aim of our study was to define long-term electrocardiographic and echocardiographic changes and complications after transcatheter closure of atrial septal defect and patent foramen ovale in adults.Methods: The clinical, electrocardiographic and echocardiographic follow-up of 137 consecutive patients that underwent transcatheter closure of atrial septal defect (51 patients or patent foramen ovale (86 patients in a 10-year period was analyzed retrospectively.Results: In the patent foramen ovale group, we observed no significant postprocedural changes. There were no changes in heart rate, heart rhythm and PR or QRS duration in both groups. In the atrial septal defect group, we observed a leftward shift in the heart axis (p = 0.017, a decrease in the estimated systolic pulmonary artery pressure (p = 0.024, decreased tricuspid early diastolic flow velocity (p = 0.002, a decrease in the right chamber dimensions (p = 0.0004 and interventricular septal movement normalization (p < 0.0001. Most of the complications were mild and occurred early after the procedure. Three early serious complications were documented.Conclusions: No electrocardiographic or echocardiographic changes occurred after patent foramen ovale closure. Atrial septal defect closure is related to significant early morphological and hemodynamic improvement. Postprocedural complications are usually early and mild but serious late complications can occur. For that reason, long-term follow up is recommended in these patients.

    Congenital intrahepatic arterioportal fistulas (APFs) are a rare cause of portal hypertension in children. Doppler US is a useful diagnostic imaging modality. Transarterial embolization is a minimally invasive and effective therapy allowing occlusion of the fistula and restoration of liver hemodynamics. To describe the clinical and radiologic findings, percutaneous treatment and role of D-US in the postembolization follow-up of children with APF. Between 2002 and 2011, four children with APF were treated. Initial diagnosis and follow-up was performed with D-US and confirmed by arteriography, followed by endovascular embolization in all patients. D-US demonstrated abnormal arterioportal communications in all patients. Six endovascular procedures were performed in these four children. In two children, no residual fistula was seen on D-US after the first procedure and symptoms resolved. In the other two children, D-US demonstrated residual flow through the fistula, with resolution of pathological D-US findings and symptoms after the second endovascular procedure. All four children were successfully treated and asymptomatic at the end of follow-up. The mean follow-up was 24 months. Interventional radiology has a key role in the treatment of congenital APF. D-US is a noninvasive and effective tool for the diagnosis and follow-up of these patients. (orig.)

    Dilatational tracheotomy techniques are widely used in the long-term management of the respiratory tract in patients in intensive care units (ICU). The translaryngeal tracheotomy technique (TLT) was first described by Fantoni in 1993 and rapidly asserted itself, especially in Europe. This technique basically differs from the other percutaneous techniques in that it involves a progressive, retrograde, dilatation of the trachea in a single session conducted from inside the trachea, working outward, simultaneously exerting a counter-pressure on the pre-tracheal soft tissues with the fingers. The present study involves an endoscopy follow-up of 130 patients who had undergone TLT at the Intensive Care Unit of our Hospital between November 2000 and May 2001. The pre-operative oro-tracheal intubation time varied from 1 to 42 days. All patients filled out a brief questionnaire containing validated questions on their general health and quality of life with particular attention focused on respiratory conditions. Then, after receiving informed consent, the patients underwent laryngo-tracheoscopy with local anesthetic using a flexible tracheobronchoscope. All tests were recorded and viewed later by two operators in order to identify and divide the patients according to the level of execution of the tracheotomy and the presence of sequelae. The results obtained have shown that, like other percutaneous tracheotomy techniques, TLT provides some benefits including the fact that procedure can be performed at the bedside in a short time, with few post-operative complications, simpler nursing and fewer sequelae in time. Analysis of data concerning time of tracheostomy execution, tracheal level of stomia and nursing times has revealed three factors that determine severe sequelae: delay in tracheostomy execution, high level of execution with cricoid involvement and onset of problems during first tracheal cannula change.

    The purpose of this study was to evaluate the technical success, complications, long-term clinical outcome, and patency after primary infrarenal aortic stenting for aortic and aortoiliac stenosis. Between January 1999 and January 2006, 22 consecutive patients underwent endovascular treatment because of infrarenal aortic stenosis with and without common iliac stenosis (10 men; mean age 64 {+-} 14 years). Eleven (11 of 22) patients had an isolated aortic stenosis, whereas 11 of 22 had aortic stenosis that extended into the common iliac arteries (CIAs). Thirteen patients were Rutherford classification type 3, and 9 patients were type 4. Statistical analysis included paired Student t test and Kaplan-Meier life table analysis; p < 0.05 was considered significant. Technical and initial clinical success was achieved in all patients. There were three (14 %) procedure-related complications, which included two access-point pseudoaneurysms and one non-flow-limiting left external iliac dissection. Patients were followed-up for a mean period of 88 months (range 60-132). Mean preprocedure ankle brachial pressure indexes (ABPI) were 0.60 {+-} -0.15 (right) and 0.61 {+-} -0.16 (left). After the procedure they were 0.86 {+-} -0.07 (right) and 0.90 {+-} -0.09 (left). The increase in ABPI was significant (p < 0.05), and this continued throughout follow-up. Four (18 %) patients had recurrence of symptoms during follow-up. These occurred at 36, 48, 48, and 50 months after the original procedure. All four patients were successfully treated with repeat angioplasty procedures. There was a significant difference in primary patency between isolated aortic stenosis (100 %) and aortoiliac stenosis (60 %) (p = 0.031). Cumulative follow-up was 1920 months yielding a reintervention rate of 0.025/events/year. Primary stenting of infrarenal stenosis is safe and successful with a low reintervention rate. It should be considered as first-line treatment for patients with infrarenal aortic stenotic

    electrodes (SPCEs were used as the transducers. These SPCEs (working volume: ~40 μL are widely employed in the construction of electrochemical (biosensors because of several reasons: simplicity and low cost, versatility of design, small dimensions and possibility of incorporation in portable systems, as well as adequate electroanalytical characteristics. These SPCEs were modified with gold nanoparticles (nAu through the electrochemical deposition of ionic gold from a solution. The developed sensors were applied to the analysis of the selected biomarkers in spiked human serum samples.Besides these immunosensors, a molecularly imprinted polymer (MIP sensor was developed for the analysis of HER2-ECD. In this case a gold electrode was used as the transducer. The MIP was formed by surface imprinting and electrochemical impedance spectroscopy and voltammetry were used for detection purposes.Results: For the immunoassays the following parameters were optimized: capture and detection antibody concentration, surface blocking, reaction mixtures and incubation times. The best limits of detection obtained were below the established cut-off values (25 U/mL and 15 ng/mL for CA15-3 and HER2-ECD, respectively. For the MIP sensor the most adequate polymer was chosen and the electropolymerization, template removal, and incubation conditions were optimized. The lowest HER2-ECD concentration that was analyzed was 50 µg/mL.Conclusion: The obtained results indicate that the developed sensors could be promising tools in breast cancer diagnostics and follow-up. However, further studies should be conducted using patients' samples and the results of these assays should be validated with the established analysis procedures for these cancer biomarkers.-----------------------------------------Cite this article as:  Marques R, Pacheco J, Rama EC, Viswanathan S, Nouws H, Delerue-Matos C.

    This paper describes the examination of findings by multi-detector-row CT (MDCT) and by surgery to obtain the anatomy of hilar arteries and portal vein, which is necessary for the procedure in the title. Subjects are those findings of 38 patients with hilar cholangiocarcinoma, who underwent its excision during the period of 1 year from 2002 Nov. Before operation, MDCT with 16-row detector was done 20-120 sec after infusion of a non-ionized contrast medium to compose the 3D images. The left hepatic arterial system was found to be classifiable in 3 types of common, anti-clockwise and clockwise one with the respective frequency of 63, 24 and 11%, and the right system, infra-portal (76%) and supra-portal (24%) types. It was concluded that to the arterial clockwise and supra-portal types, particular attention should be paid for the cancer invasion there and for avoidance of the artery damage during the operation.

    Full Text Available Outcomes of III-VI AB degree burns in children,regardless of the nature of treatment in the acute andrecovery period, are the development of scar contractures and deformities of the joints. However, thecorrect organization of follow-up care and rehabilitation treatment can significantly reduce the severity and facilitates the full recovery of the affected segment. Based on the analysis of their own material, the author defines the early stage of rehabilitation in these patients before full maturation of scar tissue or before the formation of functionally significant joint contractures, and later period, when there are indications for surgical rehabilitation. In the early period, follow-up care is recommended in 1 month after discharge and then on a quarterly basis, and with the appearance of deformities - at least once in 2 months. At the2nd stage of rehabilitation, older children and children of secondary school age are subject to follow-up care at least 1 time per year of primary school age - atleast once in 6 months, preschool children - every3 months. The proposed assessment of scar tissuehelps to determine the terms of follow-up care. Usingthis scheme of follow-up care and appropriate treatment allowed the author to obtain excellent and goodresults in 87-90 % of cases at the stages of rehabilitaion.

    To evaluate the volume change of peritoneal inclusion cysts on the follow-up ultrasonography (US). From March 1995 to May 1999, thirty seven women with ultrasonographically diagnosed peritoneal inclusion cysts were included in this study. Six patients underwent surgery for several reasons. Follow-up ultrasonography was performed 70-456 days (mean=191 days) after initial US examination in 12 of the remaining 31 patient with no further treatment. US was performed with a 3.5 or 4 MHz transabdominal probe in all 18 patients who underwent either surgery or follow-up US, and additional tranvaginal US examination using a 5-7 MHz probe in 15 of 18 patients. The volume change of the cysts was recorded for each US examination. Three cysts (25%) (volume=170 cm 3 , 61 cm 3 , and 38 cm 3 , respectively) were completely resolved on the follow-up US while the other nine cysts showed a decreased volume in seven patients (58%) and increased volume in two patients (17%). Spontaneous regression of peritoneal inclusion cysts is more common than it is believed to be, and ultrasonography may be a useful follow-up examination for peritoneal inclusion cysts.

    IMPORTANCE Follow-up with a primary care provider (PCP) in addition to the surgical team is routinely recommended to patients discharged after major surgery despite no clear evidence that it improves outcomes. OBJECTIVE To test whether PCP follow-up is associated with lower 30-day readmission rates after open thoracic aortic aneurysm (TAA) repair and ventral hernia repair (VHR), surgical procedures known to have a high and low risk of readmission, respectively. DESIGN, SETTING, AND PARTICIPANTS In a cohort of Medicare beneficiaries discharged to home after open TAA repair (n = 12 679) and VHR (n = 52 807) between 2003 to 2010, we compared 30-day readmission rates between patients seen and not seen by a PCP within 30 days of discharge and across tertiles of regional primary care use. We stratified our analysis by the presence of complications during the surgical (index) admission. MAIN OUTCOMES AND MEASURES Thirty-day readmission rate. RESULTS Overall, 2619 patients (20.6%) undergoing open TAA repair and 4927 patients (9.3%) undergoing VHR were readmitted within 30 days after surgery. Complications occurred in 4649 patients (36.6%) undergoing open TAA repair and 4528 patients (8.6%) undergoing VHR during their surgical admission. Early follow-up with a PCP significantly reduced the risk of readmission among open TAA patients who experienced perioperative complications, from 35.0% (without follow-up) to 20.4% (with follow-up) (P < .001). However, PCP follow-up made no significant difference in patients whose hospital course was uncomplicated (19.4% with follow-up vs 21.9% without follow-up; P = .31). In comparison, early follow-up with a PCP after VHR did not reduce the risk of readmission, regardless of complications. In adjusted regional analyses, undergoing open TAA repair in regions with high compared with low primary care use was associated with an 18% lower likelihood of 30-day readmission (odds ratio, 0.82; 95% CI, 0.71–0.96; P = .02), whereas no significant

    1986-01-01

    Besides individual care, regular follow-up studies in breast cancer patients have different aims, relative to different tumor stages at presentation. In early stages emphasis has to be laid on detection of loco-regional recurrences, which will not reduce overall survival if diagnosed and treated early. In addition, treatment effects and changes in the activity of disease are evaluated. Radiographic studies for detection of distant metastases are justified if followed by proper treatment. Early diagnosis of cancer of the opposite breast and of such cancers that are associated with breast cancer (colon, ovaries, endometrium) is imperative. The aim of a regular follow-up in more advanced tumor stages is to monitor the extent of disease and to prevent complications (e.g. fractures, spinal cord compression). In familial breast cancer first degree relatives should be included in the follow-up plan. The patient's psychosocial needs, even if not verbalized, should not be neglected. (Author)

    Graves' ophthalmopathy may first appear or worsen during or after treatment for hyperthyroidism. We followed up 158 Graves' hyperthyroid patients treated with radioiodine of which 49 had Grave's' ophthalmopathy during presentation in Nuclear Medicine Centre, Khulna during the period from 1995 to 2000. The aim of our study is to see the effect of radioiodine in Graves' ophthalmopathy. All the patients received radioiodine at fixed dose regime ranged from 7 mCi to 12 mCi. The duration of follow up was at least 12 months Graves' ophthalmopathy patients, 4 (4/49 i.e., 8.2%) showed exaggeration of ophthalmopathy and the rest (45/49 i.e., 91.8%) remained unchanged. None of ophthalmopathy developed among any of Graves' hyperthyroid or disappeared after radioiodine treatment during follow up period. From the study we concluded that eye changes in Graves' hyperthyroidism remain unchanged or exaggerated after radioiodine therapy and needs ophthalmologist care.(author)

    An evaluation was conducted on out-patient cognitive-behavioural anxiety management groups. Twenty-nine clients assessed before and after the group and at three-month follow-up showed significant improvement on self-report measures. A further follow-up on 21 clients, conducted by an independent assessor at an average of 11 months, showed greater improvement with time. Clients also rated how helpful they had found non-specific therapeutic factors, and specific anxiety management techniques. 'Universality' was the most helpful non-specific factor, and 'the explanation of anxiety' was the most helpful technique.

    Background/AimsRenal denervation (RDN) emerged as a treatment option for reducing blood pressure (BP) in patients with treatment-resistant hypertension (TRH). However, concerns have been raised regarding the incidence of late renal artery stenosis or thromboembolism after RDN. The goal of the current study was, therefore, to conduct a prospective clinical trial on the mid-term vascular integrity of the renal arteries and the perfusion of the renal parenchyma assessed by magnetic resonance imaging (MRI) in the follow-up after catheter-based RDN.MethodsIn our single-centre investigator initiated study, 51 patients with true TRH underwent catheter-based RDN using the Symplicity Flex{sup TM} catheter (Medtronic Inc., Palo Alto, CA). Follow-up MRI was performed at a median of 11 months (interquartile range 6–18 months) after RDN on a 1.5T MR unit. High-resolution MR angiography (MRA) and MRI results were compared to the baseline digital angiography of renal arteries obtained at time of RDN. In case of uncertainties (N = 2) catheter angiography was repeated.ResultsBoth office and 24-h ambulatory BP were significantly reduced 6 and 12 months after RDN. Renal function remained unchanged 6 and 12 months after RDN. In all patients, MRA excluded new or progression of pre-existing low grade renal artery stenosis as well as focal aneurysms at the sites of radiofrequency ablation. In none of the patients new segmental perfusion deficits in either kidney were detected on MRI.ConclusionsNo vascular or parenchymal complications after radiofrequency-based RDN were detected in 51 patients followed up by MRI.

    Andersen, Poul Erik; Kjeldsen, Anette D.

    2006-01-01

    The purpose was to evaluate the clinical and radiological long-term results of embolization of pulmonary arteriovenous malformations (PAVMs) and to assess the quality of life after treatment. A clinical follow-up was undertaken after 67 months (mean) in 35 consecutive patients with 106 PAVMs. Outcome parameters at follow-up were PaO 2 and patients' satisfaction. During follow-up, the patients had a clinical examination, measurement of arterial blood gases, chest X-ray, and contrast echocardiography performed and were asked to fill in a questionnaire exploring experience of the treatment and subjective effect of treatment on physical and social functioning. A significant rise in oxygenation of the blood after embolization was measured. In 77% of the patients symptoms improved, and 71% felt better performance. In eight patients, one of the PAVMs was found insufficiently embolized or recanalized at follow-up angiography and therefore were re-embolized. Endovascular embolization for PAVMs is effective. Clinical parameters and quality of life improved significantly. Regular clinical controls after therapy are necessary to discover insufficiently embolized, recanalized or new PAVMs

    Full Text Available Hydatid disease is caused by Echinococcus granulosus. In this study, we aimed to investigate the benefit of monitoring cases with hydatid cyst by means of immune components in patients in a long-term follow-up after surgery. Eighty-four preoperative and postoperative serum samples from 14 cases undergoing surgery for hydatid disease were evaluated in terms of immune parameters, such as total and specific IgE, IgG, IgM, IgA and complement. Total and specific IgE were determined by ELISA. Specific IgG levels were measured by indirect hemaglutination.Total IgG, IgM, IgA and complement (C3 and C4 were detected by nephelometry. Imaging studies were also carried out during the follow-up. In none of the patients hydatid cysts were detected during the follow-up. Total IgE levels in the sera of the patients decreased to normal six months after surgery. Although specific IgE against echinococcal antigens decreased one year after operation, levels were still significantly high. There were no changes in the levels of anti-Echinococcus IgG and total IgG in follow-up period. Additionally, other parameters, such as IgA, IgM, C3 and C4, were not affected.

    To assess the long-term effectiveness and safety of refractive surgery with LASIK or photorefractive keratectomy (PRK) for treating accommodative esotropia in adults. All patients with accommodative esotropia treated with LASIK or PRK until December 2007 and with a minimum follow-up of 5 years were retrospectively included. LASIK was performed on 44 eyes of 22 patients (12 women, 10 men; mean age: 22.7 ± 2.9 years). Mean postoperative follow-up was 62.1 ± 3.2 months. PRK was performed on 16 eyes of 8 patients (4 women, 4 men; mean age: 23.7 ± 1.7 years). Mean postoperative follow-up was 61.3 ± 2.8 months. At the 5-year follow-up, the mean cycloplegic refraction was more hyperopic in the PRK group (0.3 ± 0.8 vs 0.06 ± 0.3 diopters, P = .01). Correction of esotropia to esophoria or orthotropia was present in 21 patients (95.4%) treated with LASIK and in all patients treated with PRK. Both LASIK and PRK were effective in the long-term reduction of accommodative esotropia. Copyright 2014, SLACK Incorporated.

    In a two-center follow-up study on the early-onset form of anorexia nervosa, we reexamined 43 (74%) of 58 former patients who had developed anorexia nervosa at the age of 13 years or younger. In addition to make a standardized assessment of the eating disorder at follow-up we assessed psychiatric comorbidity with a structured interview based on the criteria of DSM-III-R and ICD-10. After an average follow-up period of 6.8 years, 8 (18%) of our former patients had an eating disorder not otherwise specified (EDNOS) and 4 (9%) still suffered from anorexia nervosa. 5 (11%) of the subjects had developed bulimia nervosa. In 3 cases (7%) we found both syndromes. 12 (28%) of our former patients had an additional psychiatric disorder. The results of our study indicate that the quality of outcome in patients with an early-onset form of anorexia nervosa does not differ from that in individuals with a later manifestation of the eating disorder. Factors of prognostic relevance were the existence of an eating disorder during the first year of life and the duration of the follow-up period.

    2002-01-01

    A rupture of corpus cavernosum (CC) is a rare injury of the erect penis. The present study describes the role of MRI for diagnosis and follow-up of this injury. Four patients with clinically suspected acute penile fractures underwent MRI. Imaging findings were confirmed at surgery. In three patients, follow-up MRI was also available at 1, 6 and 16 weeks after surgical repair. In all patients pre-contrast T1-weighted images (T1WI) clearly disclosed ruptures of CC, which depicted as discontinuity of low signal intensity of the tunica albuginea (TA). Concomitant subcutaneous haematoma were well visualised both on T1-weighted (T1WI) and T2-weighted images, whereas haematoma in CC were optimally demonstrated on contrast-enhanced T1WI. On follow-up MRI all fractures presented similar healing process. Shortly after the repair, the tunical suture showed an increase in signal intensity on pre-contrast T1WI and was strongly enhanced with the administration of contrast material. Then the tear site gradually recovered low signal intensity on all spin-echo sequences by 4 months after surgery. These serial findings may suggest the formation of vascularised granulation tissue during cicatrisation. Magnetic resonance imaging is of great value for the diagnosis and follow-up in patients with penile fracture. (orig.)

  16. A formula for continued improvement: Audit follow-up

    International Nuclear Information System (INIS)

    Maday, J.H. Jr.

    1989-10-01

    In his book Management Audits, Allan J. Sayle states, ''QA standards stipulate that corrective action, required as a result of performing an audit, be followed up and closed out. There would, indeed, be little point in performing audits, requiring corrective action, or having a QA system at all if the auditee knows that the auditor will never verify that the corrective action has been efficaciously implemented.'' The QA auditor has an obligation to include follow-up in the overall audit planning. All too often the auditor will go to great lengths to plan and perform an audit only to have a recurring finding in the next audit. The proposed corrective action was only promissory and was not designed to stop the problem from recurring or to identify its root cause. Auditors do a disservice to the overall QA program and particularly to the customer when they fail to follow up and verify that an audit corrective action has been effectively implemented. In this paper, the techniques used by the quality assurance auditors at the Pacific Northwest Laboratory (PNL) will be presented. Although PNL is a research and development laboratory, the techniques outlined in this paper could be applied to any industry conducting quality assurance audits. Most important, they provide a formula for continued improvement by assuring that audit follow-up is timely, meaningful, and permanent

    This study sought to compare the long-term safety and efficacy of drug-eluting balloons (DEB) and everolimus-eluting stents (EES) in patients with in-stent restenosis (ISR) of drug-eluting stents (DES). Treatment of patients with DES-ISR remains a challenge. The RIBS IV (Restenosis Intra-Stent of Drug-Eluting Stents: Drug-Eluting Balloons vs Everolimus-Eluting Stents) trial is a prospective multicenter randomized clinical trial comparing DEB and EES in patients with DES-ISR. The pre-specified comparison of the 3-year clinical outcomes obtained with these interventions is the main objective of the present study. A total of 309 patients with DES-ISR were randomized to DEB (n = 154) or EES (n = 155). At angiographic follow-up, the in-segment minimal lumen diameter was larger in the EES arm (2.03 ± 0.7 mm vs. 1.80 ± 0.6 mm; p 1 year) target lesion revascularization (2.6% vs. 4%) and target vessel revascularization (4% vs. 6.6%) was similar in the 2 arms. Rates of cardiac death (3.9% vs. 3.2%), myocardial infarction (2.6% vs. 4.5%), and stent thrombosis (1.3% vs. 2.6%) at 3 years were also similar in both arms. The 3-year clinical follow-up of this randomized clinical trial demonstrates that in patients with DES-ISR, EES reduce the need for repeat interventions compared with DEB.

    Most Strategic Environmental Assessment (SEA) research and applications have so far neglected the ex post stages of the process, also called SEA follow-up. Tool kits and methodological frameworks for engaging effectively with SEA follow-up have been conspicuously missing. In particular, little has so far been learned from the much more mature evaluation literature although many aspects are similar. This paper provides an analytical framework and tool kit for SEA follow-up. It is based on insights and tools developed within programme evaluation and environmental systems analysis. It is also grounded in empirical studies into real planning and programming practices at the regional level, but should have relevance for SEA processes at all levels. The purpose of the framework is to promote a learning-oriented and integrated use of SEA follow-up in strategic decision making. It helps to identify appropriate tools and their use in the process, and to systematise the use of available data and knowledge across the planning organization and process. It distinguishes three stages in follow-up: scoping, analysis and learning, identifies the key functions and demonstrates the informational linkages to the strategic decision-making process. The associated tool kit includes specific analytical and deliberative tools. Many of these are applicable also ex ante, but are then used in a predictive mode rather than on the basis of real data. The analytical element of the framework is organized on the basis of programme theory and 'DPSIR' tools. The paper discusses three issues in the application of the framework: understanding the integration of organizations and knowledge; understanding planners' questions and analytical requirements; and understanding interests, incentives and reluctance to evaluate

    Although improved during the past few years, blood pressure control remains sub optimal. The impact of follow-up assessment on blood pressure control was evaluated in a group of patients of the HYT (HYperTension survey), treated with a combination of different dihydropyridine calcium-channel blockers (CCBs regimen) and inhibitors of renin-angiotensin-aldosterone system (RAAS) and with uncontrolled blood pressure. This was obtained assessing (a) the rate of blood pressure control at 3 and 6 months of follow-up in the whole group of patients, (b) the rate of blood pressure control and the average blood pressure values in subjects treated with different DHP-CCBs regimen. From the 4993 patients with uncontrolled blood pressure, (BP ≥ 140/90 or ≥140/85 in patients with diabetes), 3729 (mean age 61.2 ± 11.5 years), maintained CCBs regimen combined wih RAAS blockers and were evaluated at 3 and 6 months follow-up. At each visit BP (semiautomatic device, Omron-M6, 3 measurements), heart rate, adverse events and treatment persistence were collected. At 1st and 2nd follow-up the rate of controlled BP was 63.5 and 72.8% respectively (p blood pressure control; (b) there is no significant difference in the antihypertensive effect between different CCBs regimen; (c) lipophilic CCBs induce less ankle edema.

    A CT study was carried out on 43 patients with low back pain and sciatica who were treated conservatively. They were followed up for over 20 months (mean) clinically and monitored by CT before and after treatment. Initially, 38 of them had herniation and 5 had protrusion of the disc. At the time of follow-up only 24 of the initial 40 patients still had neurological deficits. In 76.7% of the patients CT showed an improvement (clear regression in 15 patients, moderate decrease in 18 patients). A favourable tendency towards regression was observed in disc herniation at the L5-S1 level and in cases showing sequestration. The prognosis was unfavourable in herniations at higher levels than L5-S1 and in lateral herniation reaching the intervertebral foramen. (orig.) [de

  1. Role of cytology in screening, staging and follow-up

    International Nuclear Information System (INIS)

    Fischnaller, M.

    1986-01-01

    Cytology has become an integral component in the battery of diagnostic tools for a rational diagnosis of tumors. When all materials obtainable with sophisticated methods are utilized, almost every pulmonary lesion can be defined micromorphologically. In urgent cases instant staining techniques will permit a 'stat diagnosis'. The characterization of a tumor cell by cytology with accurate typing and grading offers preliminary information for subsequent staging efforts. Bronchial cancer may be both of the single-cell and of the mixed-cell type with the more aggressive cell elements determining the metastasising potential and prognosis. Sampling for cytology is devoid of risks and does not make any special demands on the patients; it can safely be repeated for follow-up studies; it helps to detect tumor regrowths or secondaries at an early stage during postoperative follow-up programs and to monitor treatment-related cellular changes.

    Hypothermia treatment for newborn infants with hypoxic-ischemic encephalopathy reduces the number of neonates who die or have permanent neurological deficits. Although this therapy is now standard of care, neonatal hypoxic-ischaemic encephalopathy still has a significant impact on the child's neurodevelopment and quality of life. Infants with hypoxic-ischaemic encephalopathy should be enrolled in multidisciplinary follow-up programs in order to detect impairments, to initiate early intervention, and to provide counselling and support for families. This article describes the main neurodevelopmental outcomes after term neonatal hypoxic-ischaemic encephalopathy. We offer recommendations for follow-up based on the infant's clinical condition and other prognostic indicators, mainly neonatal neuroimaging. Other aspects, such as palliative care and medico-legal issues, are also briefly discussed. Copyright © 2013 Asociación Española de Pediatría. Published by Elsevier Espana. All rights reserved.

Members of the Bone Metabolism Working Group of the Spanish Society of Endocrinology. A systematic search was made in MEDLINE (PubMed), using the terms normocalcemic primary hyperparathyroidism and primary hyperparathyroidism, for articles in English published before 22 November 2012. Literature was reviewed by 2 members of the Bone Metabolism Working Group of the Spanish Society of Endocrinology, and after development of recommendations, the manuscript was reviewed by all other members of the Group, and their suggestions were incorporated. The document provides practical recommendations for evaluation and follow-up of patients with normocalcemic primary hyperparathyroidism. There is however little evidence available about different aspects of this disease, mainly progression rate and clinical impact. More data are therefore needed before definite recommendations may be made. Copyright © 2012 SEEN. Published by Elsevier Espana. All rights reserved.

    2010-02-01

    Differentiated thyroid cancer rarely occurs in association with hyperfunctioning nodules. We describe a case of a 47-year-old woman who developed symptoms of hyperthyroidism associated with a palpable thyroid nodule. Thyroid scintigraphy showed an autonomous nodule, and fine-needle aspiration biopsy was suggestive of papillary carcinoma. Laboratorial findings were consistent with the diagnosis of hyperthyroidism. The patient underwent thyroidectomy and a papillary carcinoma of 3.0 x 3.0 x 2.0 cm, follicular variant, was described by histological examination. The surrounding thyroid tissue was normal. Postoperatively, the patient received 100 mCi of (131)I, and whole body scans detected only residual uptake. No evidence of metastasis was detected during five years of follow-up. Hot thyroid nodules rarely harbor malignancies, and this case illustrated that, when a carcinoma occurs the prognosis seems to be very good with no evidence of metastatic dissemination during a long-term follow-up.

    The preliminary results of a prospective study of 40 uncemented total knee prostheses (TKP) are presented following a radiological protocol with fluoroscopic control and follow-up of over 2 years. The prosthesis-bone interface and the components alignment were assessed. Several radiological signs were studied to assess this interface with respect to the fixing of the component, but they showed little clinical correlation. Statistical significance (p<0.05, chisquare) was found only in the observation of sclerosis in areas of support for the tibital tray as a reaction of the bone. This radiological follow-up is of interest to determine the evolution of the interface and position of the implant to prevent complications (especially loosening) in patients, particularly those under 60 years old, who represent the group that can most benefit from prosthetic systems with uncemented anchorage because of their life expectation and level of activity.

Guidance to authors should result in fewer, but more important, commitments for mitigating adverse environmental impacts. Selecting the significant commitments from Records of Decisions published since July 1, 1979 for tracking to satisfaction should result in conformance with regulations, orders, and the intent of the NEPA

    Based on previous experience with prenatally diagnosed unilateral hydronephrosis, we found that the primary indications for surgical intervention should be symptoms or functional impairment of the hydronephrotic kidney. Nonoperative management of neonates without symptoms and with normal function...... of the affected kidney was proposed. However, the strategy of treatment after prenatally diagnosed hydronephrosis is still controversial. We studied 28 consecutive children with suspected unilateral pelviureteral junction obstruction and a normal contralateral kidney. The overall follow-up period varied between 2...

    Little Leaguer's shoulder is a syndrome involving the proximal humeral epiphyseal plate. Conservative treatment usually resolves the symptoms. However, there are no reports of a radiographic follow-up study of this disease. The purpose of this study was to show the radiographic healing process of Little Leaguer's shoulder. A total of 19 male baseball players diagnosed as having Little Leaguer's shoulder were retrospectively evaluated. The mean age at first presentation was 12.7 years. External rotation anteroposterior radiographs of the shoulder were taken. All patients were treated with rest from throwing, and no throwing was recommended until remodeling was confirmed. Follow-up radiographs were taken at 1-month intervals to assess healing. All patients were observed until healing was confirmed radiographically, after which they returned to baseball. The mean follow-up period was 8.5 months. In addition to radiography, patients were asked whether they had any symptoms and whether they had been able to return to baseball. At the first examination, radiographs showed a wider epiphyseal plate of the throwing side compared with the asymptomatic contralateral shoulder. Healing was observed in all cases. Healing occurred first along the medial side and was then extended laterally. The mean time required for healing was 4.7 months. All patients were able to return to playing baseball at their pre-injury level of play and were asymptomatic when examined at the final follow-up. The healing process of Little Leaguer's shoulder advanced from medial to lateral, and healing was achieved about 5 months after initial examination. (orig.)

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

    Programmes for early childhood childhood hearing impairment identification allows to quickly start the appropriate hearing aid fitting and rehabilitation process; nevertheless, a large number of patients do not join the treatment program. The goal of this article is to present the results of a strategic review of the strengths, weaknesses, opportunities and threats connected with the audiologic/prosthetic/language follow-up process of children with bilateral permanent hearing impairment. Involving small children, the follow-up includes the involvement of specialised professionals of a multidisciplinary team and a complex and prolonged multi-faced management. Within the framework of the Italian Ministry of Health project CCM 2013 "Preventing Communication Disorders: a Regional Program for Early Identification, Intervention and Care of Hearing Impaired Children", the purpose of this analysis was to propose recommendations that can harmonise criteria for outcome evaluation and provide guidance on the most appropriate assessment methods to be used in the follow-up course of children with permanent hearing impairment. © Copyright by Società Italiana di Otorinolaringologia e Chirurgia Cervico-Facciale.

  14. Neonatal follow-up program: Where do we stand?

    Science.gov (United States)

    2012-01-01

    Neonatal follow-up program (NFP) is becoming the corner stone of standard, high quality care provided to newborns at risk of future neuorodevelopmental delay. Most of the recognized neonatal intensive care units in the developed countries are adopting NFP as part of their mandatory care for the best long term outcome of high risk infants, especially very low birth weight (VLBW) infants. Unfortunately, in the developing and in underdeveloped countries, such early detection and intervention programs are rarely existing, mainly because of the lack of awareness of and exposure to such programs in spite of the increasing numbers of surviving sick newborns due to advancement in neonatal care in these countries. This is a review article to explore the Neonatal follow-up programs looking at historical development, benefts and aims, and standard requirements for successful program development that can be adopted in our countries. In conclusion, proper Neonatal follow-up programs are needed to improve neonatal outcome. Therefore all professionals working in the feld of neonatal care in developing countries should cooperate to create such programs for early detection and hence early intervention for any adverse long term outcome in high-risk newborn infants PMID:27493326

    It is unclear whether mortality still is increased in acromegaly and whether there are gender-related differences. We dynamically assessed outcome during long-term follow-up in our nationwide cohort. We studied standardized mortality ratios (SMRs) relative to the general population and causes of death in acromegaly (n=333) compared with age- and gender-matched controls (n=4995). During 20 (0-33) years follow-up, 113 (34%) patients (n=333, 52% women) and 1334 (27%) controls (n=4995) died (P=0.004). SMR (1.9, 95% CI: 1.53-2.34, Pacromegaly. Overall distribution of causes of death (Pacromegaly, but not in controls, causes of deaths shifted from 44% cardiovascular and 28% cancer deaths during the first decade, to 23% cardiovascular and 35% cancer deaths during the next two decades. In acromegaly, cancer deaths were mostly attributed to pancreatic adenocarcinoma (n=5), breast (n=4), lung (n=3) and colon (n=3) carcinoma. In acromegaly, men were younger than women at diagnosis (median 44.5 vs 50 years, Pacromegaly, men are younger at diagnosis and death than women. Compared with controls, mortality is increased during 20 years of follow-up, especially in women.

    Bronchopulmonary dysplasia (BPD) is the most common complication of preterm birth, and remains a major problem in pediatric pulmonology units. The decision of discharging from the Neonatal Unit should be based on a thorough assessment of the condition of the patient and compliance with certain requirements, including respiratory and nutritional stability, and caregiver education on disease management. For proper control of the disease, a schedule of visits and complementary tests should be established prior to discharge, and guidelines for prevention of exacerbations and appropriate treatment should be applied. In this paper, the Working Group in Perinatal Respiratory Diseases of the Spanish Society of Pediatric Pulmonology proposes a protocol to serve as a reference for the follow up of patients with BPD among different centers and health care settings. Key factors to consider when planning discharge from the Neonatal Unit and during follow up are reviewed. Recommendations on treatment and prevention of complications are then discussed. The final section of this guide aims to provide a specific schedule for follow-up and diagnostic interventions to be performed in patients with BPD. Copyright © 2015 Asociación Española de Pediatría.

    We have three telescopes at BYU that we use to follow-up possible transiting planet canidates for the KELT team. These telescopes were used to collect data on Kelt-16b and Kelt-9b, which is the hottest known exoplanet. More recently we used the newest of these telescopes, a robotic 8-inch telescope on the roof of our building, to confirm the most recent Kelt planet that will be published soon. This research has been ideal for the teaching and training of undergraduate students in the art of photometric observing and data reduction. In this presentation I will highlight how we are using our membership in the Kelt team to further the educational objective of our undergraduate astronomy program, while contributing meaningful science to the ever growing field of exoplanet discovery. I will also highlight a few of the more interesting Kelt planets and the minimum telescope requirements for detecting these planets. I will then discuss the sensitivities required to follow-up future TESS candidates, which may be of interest to others interested in joining the TESS follow-up teams.

    The purposes of this study were to combine a thorough understanding of the technical aspects of the Whipple procedure with advanced rendering techniques by introducing a virtual Whipple procedure and to evaluate the utility of this new rendering technique in prediction of the arterial variants that cross the anticipated surgical resection plane. The virtual Whipple is a novel technique that follows the complex surgical steps in a Whipple procedure. Three-dimensional reconstructed angiographic images are used to identify arterial variants for the surgeon as part of the preoperative radiologic assessment of pancreatic and ampullary tumors.

    The aim of this study was to retrospectively measure the outcomes of foot-sparing surgery at one year follow-up for patients with diabetic foot ulcers (DFUs). We assessed wound healing and the need for further surgery in relation to the variables that influence healing. Data were retrospectively collected by reviewing the electronic files of patients attending the Wound Expert Clinic (WEC). Outcomes of surgical debridement, toe, ray and transmetatarsal amputations were assessed. A total of 129 cases in 121 patients were identified for inclusion. The results demonstrated that complete wound healing was reached in 52% (61/117) of the patients within 12 months. The need for additional surgery or for major amputation was 56% (n=72/129) and 30% (n=39/129) respectively. The need for an additional procedure was particularly high after surgical debridement (75%, 33/44) and transmetatarsal amputation (64%, 7/11). Risk factors for non-healing or for a major amputation were: infection (p=0.01), ischaemia (p=0.01), a history of peripheral arterial occlusive disease (p<0.01) and smoking (p=0.01). Additional findings were that not all patients underwent vascular assessment and in half of the patients there was a delay in undergoing revascularisation. The results of the study reveal some areas for improvement including timely revascularisation and performance of multiple debridement procedures if needed in order to save a limb.

    Independent Environmental Impact Assessment (EIA) follow-up verifiers such as monitoring agencies, checkers, supervisors and control officers are active on various construction sites across the world. There are, however, differing views on the value that these verifiers add and very limited learning in EIA has been drawn from independent verifiers. This paper aims to appraise how and to what extent independent EIA follow-up verifiers add value in major construction projects in the developing country context of South Africa. A framework for appraising the role of independent verifiers was established and four South African case studies were examined through a mixture of site visits, project document analysis, and interviews. Appraisal results were documented in the performance areas of: planning, doing, checking, acting, public participating and integration with other programs. The results indicate that independent verifiers add most value to major construction projects when involved with screening EIA requirements of new projects, allocation of financial and human resources, checking legal compliance, influencing implementation, reporting conformance results, community and stakeholder engagement, integration with self-responsibility programs such as environmental management systems (EMS), and controlling records. It was apparent that verifiers could be more creatively utilized in pre-construction preparation, providing feedback of knowledge into assessment of new projects, giving input to the planning and design phase of projects, and performance evaluation. The study confirms the benefits of proponent and regulator follow-up, specifically in having independent verifiers that disclose information, facilitate discussion among stakeholders, are adaptable and proactive, aid in the integration of EIA with other programs, and instill trust in EIA enforcement by conformance evaluation. Overall, the study provides insight on how to harness the learning opportunities

    This follow-up study evaluated the outcome of sex reassignment as viewed by both clinicians and patients, with an additional focus on the outcome based on sex and subgroups. Of a total of 60 patients approved for sex reassignment, 42 (25 male-to-female [MF] and 17 female-to-male [FM]) transsexuals completed a follow-up assessment after 5 or more years in the process or 2 or more years after completed sex reassignment surgery. Twenty-six (62%) patients had an early onset and 16 (38%) patients had a late onset; 29 (69%) patients had a homosexual sexual orientation and 13 (31%) patients had a non-homosexual sexual orientation (relative to biological sex). At index and follow-up, a semi-structured interview was conducted. At follow-up, 32 patients had completed sex reassignment surgery, five were still in process, and five-following their own decision-had abstained from genital surgery. No one regretted their reassignment. The clinicians rated the global outcome as favorable in 62% of the cases, compared to 95% according to the patients themselves, with no differences between the subgroups. Based on the follow-up interview, more than 90% were stable or improved as regards work situation, partner relations, and sex life, but 5-15% were dissatisfied with the hormonal treatment, results of surgery, total sex reassignment procedure, or their present general health. Most outcome measures were rated positive and substantially equal for MF and FM. Late-onset transsexuals differed from those with early onset in some respects: these were mainly MF (88 vs. 42%), older when applying for sex reassignment (42 vs. 28 years), and non-homosexually oriented (56 vs. 15%). In conclusion, almost all patients were satisfied with the sex reassignment; 86% were assessed by clinicians at follow-up as stable or improved in global functioning.

    Rivaroxaban is a United States Food and Drug Administration-approved oral anticoagulant for venous thromboembolic disease; however, there is no information regarding the safety and its efficacy to support its use in patients after open or endovascular arterial interventions. We report the safety and efficacy of rivaroxaban vs warfarin in patients undergoing peripheral arterial interventions. This single-institution retrospective study analyzed all sequential patients from December 2012 to August 2014 (21 months) who were prescribed rivaroxaban or warfarin after a peripheral arterial procedure. Our study population was then compared using American College of Chest Physicians guidelines with patients then stratified as low, medium, or high risk for bleeding complications. Statistical analyses were performed using the Student t-test and χ 2 test to compare demographics, readmissions because of bleeding, and the need for secondary interventions. Logistic regression models were used for analysis of variables associated with bleeding complications and secondary interventions. The Fisher exact test was used for power analysis. There were 44 patients in the rivaroxaban group and 50 patients in the warfarin group. Differences between demographics and risk factors for bleeding between groups or reintervention rate were not statistically significant (P = .297). However, subgroup evaluation of the safety profile suggests that patients who were aged ≤65 years and on warfarin had an overall higher incidence of major bleeding (P = .020). Patients who were aged >65 years, undergoing open operation, had a significant risk for reintervention (P = .047) when they received rivaroxaban. Real-world experience using rivaroxaban and warfarin in patients after peripheral arterial procedures suggests a comparable safety and efficacy profile. Subgroup analysis of those requiring an open operation demonstrated a decreased bleeding risk when rivaroxaban was used (in those aged <65

    Full Text Available Various postoperative complications have been reported after the use of tension-free vaginal tapes (TVT. The transobturator approach was introduced to minimize the potential complications. The next generation of recently introduced TVT-SECUR is intended to minimize the incidence of complications. Herein we report a case of internal pudendal artery injury sustained during this procedure that was successfully treated by radiological embolization. Angiography with vessel embolization, when available, should be considered when the arterial injury is suspected.

    Objective: To demonstrate the safety and feasibility of the transpedal approach as an alternate arterial access site for iliac artery intervention. Background: The common femoral artery is the traditional access site for the endovascular treatment of iliac artery stenoses. However, this approach is associated with complication rates as high as 2%, including retroperitoneal bleeding which carries high patient morbidity and mortality. Furthermore, the standard femoral approach is associated with longer recovery times and longer time to ambulation which are important considerations especially when performing procedures in an ambulatory setting. Methods: Twelve patients were prospectively followed after treatment for symptomatic iliac artery stenosis via transpedal access. Under ultrasound guidance, one of the pedal arteries was visualized and accessed, and stenting of the iliac arteries were performed as per protocol. The patient was monitored immediately post procedure and clinical follow up was performed at one week and one month later. Results: The average age of the patients was 71 years old. 58% were male. Most patients had Rutherford class III symptoms. Successful stent placement was achieved in all 12 patients via transpedal access. No conversion to femoral access was required. No complications immediately post procedure nor at any time period during follow up were noted. Lower extremity arterial duplex at one month showed patent stents and patent pedal access site vessels in all patients. Conclusion: Transpedal arterial access may be a safe and feasible approach for iliac artery stenting. Given the possible benefits of avoiding femoral artery access, larger studies should be conducted directly comparing the different approaches.

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

  7. Can JWST Follow Up on Gravitational-Wave Detections?

    Bitten by the gravitational-wave bug? While we await Thursdays press conference, heres some food for thought: if LIGO were able to detect gravitational waves from compact-object mergers, how could we follow up on the detections? A new study investigates whether the upcoming James Webb Space Telescope (JWST) will be able to observe electromagnetic signatures of some compact-object mergers.Hunting for MergersStudying compact-object mergers (mergers of black holes and neutron stars) can help us understand a wealth of subjects, like high-energy physics, how matter behaves at nuclear densities, how stars evolve, and how heavy elements in the universe were created.The Laser Interferometer Gravitational-Wave Observatory (LIGO) is searching for the signature ripples in spacetime identifying these mergers, but gravitational waves are squirrelly: LIGO will only be able to localize wave sources to tens of square degrees. If we want to find out more about any mergers LIGO discovers in gravitational waves, well need a follow-up search for electromagnetic counterparts with other observatories.The Kilonova KeyOne possible electromagnetic counterpart is kilonovae, explosions that can be produced during a merger of a binary neutron star or a neutron starblack hole system. If the neutron star is disrupted during the merger, some of the hot mass is flung outward and shines brightly by radioactive decay.Kilonovae are especially promising as electromagnetic counterparts to gravitational waves for three reasons:They emit isotropically, so the number of observable mergers isnt limited by relativistic beaming.They shine for a week, giving follow-up observatories time to search for them.The source location can beeasily recovered.The only problem? We dont currently have any sensitive survey instruments in the near-infrared band (where kilonova emission peaks) that can provide coverage over tens of square degrees. Luckily, we will soon have just the thing: JWST, launching in 2018!JWSTs

    The goal of this study was to describe early and midterm outcomes of extremely premature newborns (EPNs) who underwent transcatheter echocardiographically guided patent ductus arteriosus (PDA) closure. Surgical ligation of PDA in EPNs confers significant risk for procedural morbidity and adverse long-term outcomes. The Amplatzer Vascular Plug II was used in all cases. Post-ligation syndrome was defined using previously published parameters. Patients were followed at pre-specified intervals, and prospectively collected data were reviewed. Transcatheter closure was attempted in 24 EPNs (mean procedural age 30 days [range 5 to 80 days], mean procedural weight 1,249 g [range 755 to 2,380 g]) and was successful in 88%. The 3 procedural failures were related to the development of left pulmonary artery (LPA) stenosis caused by the device, and all devices were removed uneventfully. Complications included 2 instances of device malposition, resolved with device repositioning, and 1 instance of LPA stenosis, requiring an LPA stent. There were no procedural deaths, cases of post-ligation syndrome, residual PDA, or device embolization. Survival to discharge was 96% (23 of 24), with a single late death unrelated to the procedure. After a median follow-up period of 11.1 months, all patients were alive and well, with no residual PDA or evidence of LPA or aortic coarctation. This newly described technique can be performed safely with a high success rate and minimal procedural morbidity in EPNs. Early and midterm follow-up is encouraging. Future efforts should be directed toward developing specific devices for this unique application. Copyright © 2016 American College of Cardiology Foundation. Published by Elsevier Inc.

    Menopausal transition is associated with increased dissatisfaction with sleep, but the effects on sleep architecture are conflicting. This prospective 6-year follow-up study was designed to evaluate the changes in sleep stages and sleep continuity that occur in women during menopausal transition. Sixty women (mean age 46.0 years, SD 0.9) participated. All women were premenopausal at baseline, and at the 6-year follow-up, women were in different stages of menopausal transition. Polysomnography was used to study sleep architecture at baseline and follow-up. The effects of aging and menopause (assessed as change in serum follicle-stimulating hormone [S-FSH]) on sleep architecture were evaluated using linear regression models. After controlling for body mass index, vasomotor, and depressive symptoms, aging of 6 years resulted in shorter total sleep time (B -37.4, 95% confidence interval [CI] -71.5 to (-3.3)), lower sleep efficiency (B -6.5, 95%CI -12.7 to (-0.2)), as well as in increased transitions from slow-wave sleep (SWS) to wakefulness (B 1.0, 95%CI 0.1 to 1.9), wake after sleep onset (B 37.7, 95%CI 12.5 to 63.0), awakenings per hour (B 1.8, 95%CI 0.8 to 2.8), and arousal index (B 2.3, 95%CI 0.1 to 4.4). Higher S-FSH concentration in menopausal transition was associated with increased SWS (B 0.09, 95%CI 0.01 to 0.16) after controlling for confounding factors. A significant deterioration in sleep continuity occurs when women age from 46 to 52 years, but change from premenopausal to menopausal state restores some SWS. © Sleep Research Society 2017.

    on graft vessel type, anastomatic configuration, and coronary artery size. RESULTS: Nine hundred eighty-two coronary anastomoses were performed of which 12% had signs of graft failure at one year angiographic follow-up. In internal mammary arteries (IMAs), analysis showed a 4% decrease in graft failure......BACKGROUND: Transit-time flow measurement (TTFM) is a commonly used intraoperative method for evaluation of coronary artery bypass graft (CABG) anastomoses. This study was undertaken to determine whether TTFM can also be used to predict graft patency at one year postsurgery. METHODS: Three hundred...... forty-five CABG patients with intraoperative graft flow measurements and one year angiographic follow-up were analyzed. Graft failure was defined as more than 50% stenosis including the "string sign." Logistic regression analysis was used to analyze the risk of graft failure after one year based...

    Primary tumors of the brain and cerebral metastases cause considerable morbidity and mortality. To assess the chance for cure and to develop a valid concept of treatment, the exact assessment of the tumor's location, of the tumor's borders and malignancy is essential. Today, neuroradiological examination mainly with magnetic resonance imaging (MRI) allows an almost histological diagnosis and description of the tumor's extent. MRI is as well useful for studying the patient's short- and long-term follow-up clinical course. This is illustrated by 3 case histories. (orig.)

    With increasing numbers of long survival patients in biliary atresia, associated diseases such as liver cirrhosis and portal hypertension seem to be more important in their course. We use liver scintigraphy, hepatobiliary scintigraphy and transrectal portal scintigraphy as the follow-up study. Three studies generally correlate the present state of the patients, but there seems to be dissociation in the group of cirrhosis without icterus which are encountered most often in biliary atresia. That can be seen in hepatobiliary scintigraphy especially. So we emphasis that to choose several isotope studies are essential in determination of the postoperative state in biliary atresia.

    1982-06-01

    Twenty-four patients received ECT induced by either alternating sine wave or brief pulsed-square wave stimulus and were evaluated at follow-up for clinical functioning and subjective memory loss. The hypothesis of less memory loss in the group receiving a weaker stimulus (pulsed-square wave) was not supported. The two treatment groups and a group of controls showed no significant differences on the memory test. On measures of clinical functioning the sine wave group scored better on every measure than the square wave group, although not significantly better.

    A follow-up of the transients of temperature and pressure in the primary pressurized system of a nuclear power plant has been completed for the Barsebaeck-1 reactor. The investigation consists of the following steps:- the collation of transients - drawing up load data based on transients-analyses of stress - recommendations for future programs. It was found that the lifetime of the system will exceed 40 years excluding some of the pipes for feed water. The appendices give a detailed description of the transients.(G.B.)

    The aim of this study was to follow-up a group of children and young people previously examined for psychological sequelae following road traffic accidents. The group was assessed 18-month postaccident to assess the severity of continuing symptoms and examine any emergence of delayed onset of posttraumatic stress reactions. Participants (N = 31) completed the Revised Impact of Event Scale and the Child Posttraumatic Stress Reaction Index. Parents completed the Child Behavior Check-List and participated in a semistructured interview. Symptoms of PTSD were noted in a quarter of participants as was delayed onset of symptoms. The role of avoidance in symptom reporting and continuing disorder is discussed.

    Smith, M.E.

    In response to increasing demand for human data to identify social, environmental, and occupational influences upon health, Statistics Canada has been organizing existing files of vital and health records to facilitate such studies on a national scale. In particular, the development of a Canadian Mortality Data Base file, the initiation of the National Cancer Incidence system, and the development of new computer techniques have helped reduce the cost and increase the scale and efficiency of automated medical follow-up to produce statistics of sickness or death attributable to environmental factors. Specific occupational studies now in progress serve to illustrate the methods, practical difficulties, potential size, and products from such investigations

    Nine patients undergoing regular dialytic treatment for more than 60 months showed clinical and radiologic features of a noninfective and destructive spondyloarthropathy. Typically, radiographs and CT scans revealed narrowing of intervertebral spaces, with destruction or sclerosis of the subchondral bone of the vertebral plate. A radiographic follow-up of the cervical spine was performed in seven patients after a period of 12 months and showed that the bone destruction in DSA is very rapid and progressive. The lower biocompatibility of the cuprophan membranes of dialyzers is probably the factor most responsible for hyperproduction of β 2 -m and subsequently osteoarticular deposition of a new type of amyloidosis.

    A proposed simplified method for evaluating elastic follow-up effects in high temperature pipelines is presented. The method was evaluated by comparing the simplified analysis results with those obtained from detailed inelastic solutions. Nine different pipelines typical of a nuclear breeder reactor power plant were analyzed; the simplified method is attractive because it appears to give fairly accurate and conservative results. It is easy to apply and inexpensive since it employs iterative elastic solutions for the pipeline coupled with the readily available isochronous stress-strain data provided in the ASME Code

    In the last century, with the advancement of the diagnostic procedures, hematologic disorders in pediatric age group have been increased dramatically. In parallel with this increase, splenectomy procedures have also been popularized with different techniques and surgical outcomes. Laparoscopic splenectomy (LS) in the pediatric age group is generally accepted as a technically demanding procedure, which needs experience. The purpose of this study is to present the long-term follow-up results of a case series of children who underwent LS for a variety of hematologic disorders, evaluate possible complications and outcomes. All patients who were admitted to the clinic and who were scheduled for LS from 2005 to 2016 were considered for this study. The study parameters were grouped in four categories including socio-demographic data, preoperative evaluation, clinical follow-up and complications. There were 24 male (48.9%) and 25 (51.1%) female patients. The median age and body weight for the study group was 12 years and 35 kg. Most common indications for LS were thalassemia (13; 26.5%) and hereditary spherocytosis (12; 24.4%). As a technical standpoint, 2 patients (4%) underwent singleport LS surgery. The mean time for LS surgeries was found as 80 minutes. The total intraoperative complication rate was 4% (2/57). The mean time for hospital stay was 5 days. Mean follow-up period was 6.4 years (range: 6 months-16 years). There was no long-term complication. Bilirubin levels and need for blood transfusion significantly decreased in the long term follow-up period (p <0.05). LS is a powerful tool in the hands of an experienced surgeon. It's a safe and effective procedure in children with hematologic disorders resulting in shorter length of stay and lower complication rates. Sociedad Argentina de Pediatría

    Long-term follow-up results after embolization of 13 pulmonary arteriovenous malformations in 10 patients by use of 14 detachable silicone balloons are given. Patients were followed for a mean of 99 months (range, 63-123 months) with chest x-rays and for a mean of 62 months (range, 3-101 months) with pulmonary angiography. Fifty-four percent of the balloons were deflated at latest radiographic chest film follow-up, but at pulmonary angiographic follow-up all embolized malformations were without flow irrespective of whether or not the balloons were visible. Detachable silicone balloons are not available anymore, but use of these balloons for embolization of pulmonary arteriovenous malformations has been shown to be a safe and precise method, with immediate occlusion of the feeding artery and with long-lasting occlusion, even though many balloons deflate with time, leaving a fibrotic scar replacing the pulmonary arteriovenous malformation. No case of recanalization has been discovered, and these results seem to justify a reduced number of controls of these balloon-embolized malformations

    Full Text Available Only sparse data was available on long-term of Takotusbo Cardiomyopathy (TC. Previous studies suggested prognosis is not necessarily benign. We report the long-term follow-up of 12 TC patients actively managed with risk factor reduction. Retrospective analysis of all patients diagnosed with TC at our hospital between 1998 and 2010. We identified 12 patients with TC among 1651 cases of emergent left heart catheterization over 12 years. Mean follow-up time was 8.3 ± 3.6 years. All were female, 87% had hypertension, 25% had history of Coronary Artery Disease (CAD, 67% had hyperlipidemia, 44% had some preceding emotional trauma, and 44% had some physical/physiological stress. Previous studies have shown that over 50% of TC patients experience future cardiac events, and 10% have a recurrence of TC. Patients were prescribed therapeutic lifestyle changes (TLC and guideline directed medical therapy (GDMT for aggressive risk factor reduction. TLC included diet, exercise, and cardiac rehabilitation. GDMT often included aspirin, beta-blockers, ACE-inhibitors, and statins. Follow-up echocardiograms showed recovery and maintenance of the ejection fraction. There was no cardiac mortality and no recurrences of TC. Aggressive risk factor reduction with TLC and GDMT may be effective in improving the long term outcomes of patients with TC.

    The aim of this study was to assess the influence of thoracic anterior radiculomedullary artery (tARMA) distribution on spinal cord perfusion in a thoracic aortic surgical model. Twenty-six pigs (34 ± 3 kg; study group, n = 20; sham group, n = 6) underwent ligation of the left subclavian artery and thoracic segmental arteries. End points were spinal cord perfusion pressure (SCPP), regional spinal cord blood flow (SCBF), and neurologic outcome with an observation time of 3 hours. tARMA distribution patterns tested for an effect on end points included (1) maximum distance between any 2 tARMAs within the treated aortic segment (0 or 1 segment = small-distance group; >1 segment = large-distance group) and (2) distance between the end of the treated aortic segment and the first distal tARMA (at the level of the distal simulated stent-graft end = group 0; gap of 1 or more segments = group ≥1). The number of tARMA ranged from 3 to 13 (mean, 8). In the large-distance group, SCBF dropped from 0.48 ± 0.16 mL/g/min to 0.3 ± 0.08 mL/g/min (p distribution patterns of tARMAs correlate with the degree of SCBF drop and insufficient reactive parenchymal hyperemia in aortic procedures. Individual ARMA distribution patterns along the treated aortic segment could help us predict the individual risk of spinal ischemia. Copyright © 2017 The Society of Thoracic Surgeons.

    Objective: To investigate the clinical applications of 64-MSCTA for the follow-up of endovascular stent-graft exclusion (EVE). Methods: Between Oct 2006 and Feb 2008, forty-four 64-MSCTA examinations were performed in 30 patients with aortic dissection (AD) and 5 patients with abdominal aortic aneurysm (AAA) who underwent EVE. Imaging reconstruction including MPR, MIP and VR were finished on workstation. The outcomes and complications after EVE of aortic dissection and aortic aneurysm were evaluated. Results: (1) Of 30 patients with aortic dissection, large thrombosis in false lumen was observed in 28 cases and small thrombosis in 2 cases. The cavity of aortic aneurysm outside the stent was thrombosed completely in 5 patients with AAA. (2) Thrombosis in the innominate artery on follow-up CTA after EVE was found in 1 AD patient with the innominate artery involved, Thrombosis in the superior mesenteric artery was observed on 15 days follow-up CTA but thrombolysis on 3 months after EVE in 1 case, Intimal tear in right common iliac artery was found in 1 case. Of 5 patients with AAA, occlusion of right inner iliac artery was observed in 1 case, and instent thrombosis in distal right common iliac artery was found in 1 case. (3) Endoleak was found in 14 patients with AD, including 8 with type I and 6 with type III endoleaks, one type III endoleak was disappeared on follow-up CTA after 3 months. Conclusions: 64-MSCTA with fast, non-invasive and effective merits, combining multiple reconstructive methods, has become one of preferred imaging methods in post-operative evaluation of EVE.

    Objective: To evaluate the long-term effect of coronary stenting in young coronary artery diseased patients ( 45) undergoing coronary stenting were chosen randomly as the control group. Comparison the general characteristics, coronary angiographies, interventional and follow-up information between the two groups was undertaken. Results: Comparing with the control group, the young group patients presented much more myocardial infarctions (68% vs 35%, P<0.05) and single-vessel disease (83% vs 57%, P=0.001). Complete revascularization was achieved in 95% patients in the young group (95% vs control 78%, P=0.004). With a mean 67 ± 9 months follow-up, recurrent angina and readmission rate were higher in the young group, as well as the incidence of MACE. Repeat CAG revealed much more de novo lesions in the young group (44% vs 11%, P=0.02) and higher rate of re-stenting. Conclusions: Due to the high rate of complete circulatory reconstruction in young patients, the postprocedural events are probably caused by new coronary arterial lesions; therefore coronary stenting should be regarded as the primary choice of treatment.

    In 54 patients who were diagnosed as having Alzheimer's type dementia based on the Diagnostic and Statistical Manual of Mental Disorders, III, cranial computed tomography (CT) scans were obtained before and after their follow-up study ranging from 6 to 24 months (mean 15.4 +- 4.7 months). Cerebrospinal percentage and CT density in various regions of interest were examined. Six patients died during the study. Comparison of the group of the deceased (Group I) with the group of survivors (Group II) revealed: (1) there was no difference in average age and the degree of mental disorder at first presentation; (2) Group I had decreased activities of daily living; and (3) CT density was significantly decreased in the bilateral lateral and frontal lobes in Group I. As for Group II, decreased CT numbers were noticeable during the follow-up period in the frontal lobe, parietal lobe, and caudate nucleus in the group evaluated as aggravated, as compared with the group evaluated as unchanged.

    Full Text Available Rothmund-Thomson syndrome (RTS is a rare autosomal recessive disorder presenting with poikiloderma and other clinical features, affecting the bones and eyes and, in type II RTS, presenting an increased risk for malignancy. With about 300 cases reported so far, we present a 13-year follow-up including clinical images, X-rays and genetic analysis. A 13-month-old female started with a facial rash with blisters on her cheeks and limbs at the age of 3 months along with congenital hypoplastic thumbs, frontal bossing and fine hair, eyebrows and eyelashes. The patient was lost to follow-up and returned 12 years later with palmoplantar hyperkeratotic lesions, short stature, disseminated poikiloderma and sparse scalp hair, with absence of eyelashes and eyebrows. Radiographic analysis showed radial ray defect, absence of the thumb and three wrist carpal bones, and reduced bone density. Gene sequencing for the RECQL4 helicase gene revealed a mutation on each allele. RTS is a rare disease, and in this patient we observed the evolution of her skin lesions and other clinical features, which were important for the classification of type II RTS. The next years will provide even more information on this rare disease.

    1986-01-01

    Blood flow recovery in a group of 69 patients with pulmonary embolism was followed by serial lung scans over a six month period. Each patient underwent perfusion lung scan at diagnosis then 7, 30 and 180 days later; i.v. heparin was systematically administered for one week after diagnosis, followed by oral warfarin for six months. Blood flow impairment was evaluated by assessing the total number of unperfused lung segments (ULS), as calculated on both lateral views at each scan. The number of ULS was significantly reduced at each interval (P<0.001), ranging from 8.4±3.3 at diagnosis to 3.6±2.7 six months later; most of the recovery (79%) occurred within the first month. No patient had complete restoration of pulmonary blood flow during the whole follow-up period. No difference was found between the number of ULS in right lung versus that in left lung at each interval. Recovery of blood flow was heavily affected by coexisting cardiac or pulmonary disease. In fact, those patients with underlying cardiopulmonary disease (49.2% of the total) showed significantly smaller perfusion improvement after six months (P<0.001). Eight patients (6 with and 2 without cardiopulmonary disease) had clinical and scintigraphic evidence of recurrent embolism during the follow-up period

    Purpose: To assess the efficacy of self-expanding metallic stents in treating inoperable gastric and duodenal stenoses during follow-up and to evaluate the complications encountered.Methods: A total of 31 patients suffering from gastroduodenal obstruction (29 malignant, 2 benign) were treated with a self-expanding metallic stent (Wallstent). In 24 cases insertion was by the peroral route, in seven cases via gastrostomy.Results: All the strictures were successfully negotiated under fluoroscopic guidance without having to resort to endoscopy. A total of 27 patients (87%) were able to resume a regular diet, a soft diet, or a liquid diet orally. Complications included one case of stent malpositioning, one case of leakage of ascitic fluid through the gastrostomy orifice, one case of perforation and fistula to the biliary tree, and two cases of hematemesis. In two patients (6%) additional stents were implanted to improve patency. In all patients follow-up was maintained until death. Recurrence of symptoms immediately before death occurred in seven cases (23%). Mean survival time of patients was 13.3 weeks (SE ± 4.6).Conclusions: The deployment of gastroduodenal stents resulted in good palliation of inoperable gastric and duodenal stenoses. Certain technical aspects, e.g., adaptation of stents to bowel morphology, is critical to proper stent function and avoidance of complications

    Between 1973 and 1985, 105 patients received radiation therapy as all or part of their treatment for pituitary tumor at the New York University Medical Center. Of these, 48 patients underwent computed tomography (CT) at a minimum of 2 years following treatment, with detailed reports available for analysis of tumor regression. There were 28 men with a median age of 46 years (range, 18-71 years) and 20 women with a median age of 53 years (range, 28-80 years). Tumors were classified as secretory in 23 patients, nonsecretory in 21, and undetermined in four. Sixteen patients were treated with radiation therapy alone, 23 patients with surgery and radiation therapy, and the other with bromocriptine and radiation therapy, with or without surgery. With a median follow-up of 5 years (range, 2-14 years), 16 patients developed an empty sella, 25 patients had residual sellar mass, and seven patients had persistent extrasellar components or no change in their intrasellar mass. Among patients who did not have hypopituitarism at the inception of radiation therapy, five of 13 with empty sellas and 12 of 22 with residual mass subsequently required therapy. The authors conclude that residual mass is commonly found in long-term follow-up after radiation therapy, that isolated imaging studies revealing such findings after treatment in no way herald a diagnosis of recurrence, and that hypopituitarism following pituitary radiation therapy does not correlate with the ablation or persistence of tissue within the sella

    To review the literature on retention strategies in follow-up studies and their relevance to critical care and to comment on the Toronto experience with the acute respiratory distress syndrome (ARDS) and severe acute respiratory syndrome (SARS) follow-up studies. Literature review and two cohort studies in a tertiary care hospital in Toronto, Canada. ARDS and SARS patients. Review articles from the social sciences and medicine are summarized and our own experience with two longitudinal studies is drawn upon to elucidate strategies that can be successfully used to attenuate participant drop-out from longitudinal studies. Three key areas for retention of subjects are identified from the literature: (a) respect for patients: respect for their ideas and their time commitment to the research project; (b) tracking: collect information on many patient contacts at the initiation of the study and outline tracking procedures for subjects lost to follow-up; and (c) study personnel: interpersonal skills must be reinforced, flexible working hours mandated, and support offered. Our 5-year ARDS and 1-year SARS study retention rates were 86% and 91%, respectively, using these methods. Strategies to reduce patient attrition are time consuming but necessary to preserve internal and external validity. When the follow-up system is working effectively, researchers can acquire the necessary data to advance knowledge in their field and patients are satisfied that they have an important role to play in the research project.

    Full text: Breast cancer is one of the most common cancers in women. It is the second most widespread cancer in Mexican women. Among the several methods for diagnosis and follow up of the disease, tumor markers like CA-53 have high sensitivity and specificity. Bone scan is a useful method in the detection of bone metastases. In comparison to other diagnostic modalities, bone scan is more sensitive and less expensive for detection of early bone abnormalities and hence to select an appropriate treatment for better prognosis. In our country, in about 70% of cases diagnosis of breast cancer is made when the disease is in an advanced state - states III and IV. The aim of this study was to evaluate the follow up of breast cancer by bone scans and to correlate these findings with the stage of the disease and other diagnostic modalities. The work was carried out at Mexican General Hospital. A total of 350 patients with breast tumor were included; bone scans were performed in all patients at the time of clinical diagnosis and at every 6 months for a period of 1 to 5 years using an Elscint APEX SP6 HR gamma camera coupled with ultra high resolution collimator. Scan was performed 2-3 hours after intravenous administration of 555-925 MBq of Tc-99m methyl diphosphonate. Tumor classification was made according to TNM criteria. Serum levels of alkaline phosphates, carcino-embrionic antigen (CEA) and Ca 53 were also measured on the same day. Fifty-one patients confirmed to have a diagnosis of benign breast were excluded from the study group. Of the remaining 299 patients, 89 (39%) were between 41 years to 50 years, 69 between 51 to 60 years. The clinical stage most commonly observed was stage III (n=164, 54%) followed by stage II (25%). In 59.5% of patients, scintigraphy showed bone metastasis. Four patients with bone metastases showed regression and 42 (14%) with negative scans became positive on follow up bone scans. Ninety-three patients were free of bone metastases during all

    Hemorrhoidal disease is a common proctologic disorder. The HemorPex System(®) (HPS) (Angiologica, S. Martino Siccomario PV, Italy) is an innovative surgical technique based on muco-hemorrhoidopexy without Doppler guidance. The aim of this study was to evaluate the efficacy of HPS in on the treatment of grade II and III hemorrhoids. One hundred patients with grade II and III hemorrhoidal disease were included in the study and operated on using HPS without Doppler guidance. The procedure consists of a mucopexy carried out by means of a dedicated rotating anoscope in the 6 relatively constant positions of the terminal branches of the superior hemorrhoidal artery. A direct follow-up was carried out on 100 patients for up to 3 months. A late analysis (>12 months postoperatively) was conducted by telephone interview. At follow-up the following parameters were considered: pain, bleeding, prolapse, difficulties with hygiene and patient satisfaction with treatment. Operative time was 16 ± 5 min. Three-month follow-up showed significant improvement of symptoms: pain was present in 10 (10 %) patients versus 45 (45 %) preoperatively; bleeding in 13 (13 %) of patients versus 57 (57 %) preoperatively; prolapse in 13 (13 %) of patients versus 45 (45 %) preoperatively and difficulties with hygiene in 1 (1 %) versus 24 (24 %) preoperatively (all p hemorrhoidal disease. Our results show that this simple technique may be an effective but due to the important limitations of this study (loss to follow-up, non-comparative study) further studies are required.

    Despite laparoscopic partial nephrectomy and laparoscopic cryotherapy being performed lately, an even less invasive treatment would be desirable in high-risk patients. Under local anesthesia with intravenous (i.v.) sedation, we were able to perform percutaneous radiofrequency ablation (RFA) combined with renal arterial embolization for unresectable stage 1 (T1NoMo) renal cell carcinoma (RCC). We evaluated the feasibility, safety and therapeutic effects of this technique after a 2-year mean follow up. Thirty-one patients who were not candidates for surgery underwent RFA for 36 stage 1 RCC. Twenty-eight tumors were percutaneously ablated 6 days after the tumor vessels were embolized. Dynamic contrast-enhanced computed tomography (CT) and magnetic resonance imaging (MRI) were performed to evaluate treatment at completion. Tumor enhancement was eliminated after two RFA sessions in all tumors. Thirty tumors remained free of enhancement during a mean follow-up period of 24.3 months. There were no major complications related to the procedures though one instance of pyonephrosis, two of subcapsular hematomas, one of retroperitoneal hemorrhage and one of nausea were seen after RFA. Two patients died of other diseases (id est (i.e.) colon cancer and cerebral bleeding) 20 and 26 months after RFA treatment. One patient had a local recurrence of tumor and underwent re-RFA. The recurrence rate of RCC after successful RFA was 2.8%. There was no recurrence in patients who had tumors of less than 4 cm after RFA at a mean follow-up period of 24.3 months. Local control was achieved in 100% of T1NoMo tumors including the recurrence case that underwent re-RFA. The result of the present study at 2-year mean follow up showed percutaneous RFA was a feasible, safe and promising therapy for the treatment of unresectable stage 1 RCC, especially those smaller than 4 cm.

    106 patients, 114 W, 27 M, were thyroidectomized for differentiated thyroid cancer (follicular 29.3% - papillary 54.3%) with different stages of gravity (N O: 48.2% - N 1: 32.8% - N 2: 19%). Neck dissection was used in cases of involved nodes. One or several doses of 131 I were given to 126 subjects, 106 patients were treated with L thyroxine (LT4) (mean daily dose: 2.5 μg/kg BW). 23 patients presenting intolerance to LT4 with non suppressed TSH for 13 of them were treated by an association of tiratricol (TRIAC) + LT4. The follow up included a yearly check up involving clinical examination, plasma thyroglobulin (Tg) and thyroid stimulating hormone (TSH) assessment, neck ultrasonography and X ray of the chest. Therapy was stopped for 4 weeks in cases with Tg above its detectable value and a total body scan performed with Tg and TSH controls. The mean duration of follow up was 94.5 ± 67.7 months and extended to more than 5 years for 61% of the patients. We observed 22 relapses of the tumor with 4 deaths. Age less then 45 years, appears as the best factor of prognosis. 2 groups of patients were compared to evaluate the incidence of TSH suppression on the relapse free survival (group 1 n = 30 with a TSH ≤ 0.10 mU/1 and group 2 n = 15 with a TSH always > 1 mU/1 during the follow up). The relapse free survival was shorter in group 2 (p 0.01). Association of TRIAC with LT4 leads to a reduction of the daily dose of LT4 (m 25μg/day) with a significant improvement of TSH suppression and clinical tolerance. In conclusion, TSH suppression improves the prognosis in thyroidectomized patients for differentiated carcinoma. Association of TRIAC with LT4 seems able to approve TSH suppression and therapeutic tolerance. (authors). 40 refs., 5 tabs

    Vaginismus is mostly unknown among clinicians and women. Vaginismus causes women to have fear, anxiety, and pain with penetration attempts. To present a large cohort of patients based on prior published studies approved by an institutional review board and the Food and Drug Administration using a comprehensive multimodal vaginismus treatment program to treat the physical and psychologic manifestations of women with vaginismus and to record successes, failures, and untoward effects of this treatment approach. Assessment of vaginismus included a comprehensive pretreatment questionnaire, the Female Sexual Function Index (FSFI), and consultation. All patients signed a detailed informed consent. Treatment consisted of a multimodal approach including intravaginal injections of onabotulinumtoxinA (Botox) and bupivacaine, progressive dilation under conscious sedation, indwelling dilator, follow-up and support with office visits, phone calls, e-mails, dilation logs, and FSFI reports. Logs noting dilation progression, pain and anxiety scores, time to achieve intercourse, setbacks, and untoward effects. Post-treatment FSFI scores were compared with preprocedure scores. One hundred seventy-one patients (71%) reported having pain-free intercourse at a mean of 5.1 weeks (median = 2.5). Six patients (2.5%) were unable to achieve intercourse within a 1-year period after treatment and 64 patients (26.6%) were lost to follow-up. The change in the overall FSFI score measured at baseline, 3 months, 6 months, and 1 year was statistically significant at the 0.05 level. Three patients developed mild temporary stress incontinence, two patients developed a short period of temporary blurred vision, and one patient developed temporary excessive vaginal dryness. All adverse events resolved by approximately 4 months. One patient required retreatment followed by successful coitus. A multimodal program that treated the physical and psychologic aspects of vaginismus enabled women to achieve

    Objective: To recognize the mammographic changes after conservation therapy for breast carcinoma. Methods: A total of 139 follow-up mammographic examinations in 85 cases were studied during the period between 1999 and 2004. Mammography was performed at intervals of 6 months for the first 2 years, then annually. Attention was paid to mammographic change patterns of conservation therapy for breast carcinoma, including breast edema, skin thickening, architectural disturbance, asymmetric density, architectural distortion retraction, and calcifications. SPSS version 11.0 for windows was used to perform all statistical tests. Kruskal-Wallis H test was used for calculating the overall statistical differences between difference periods. Categorical data were expressed as percentages and analyzed by using the X 2 test. The age of the patients ranged from 25 to 63 years (mediate, 44 years old). The time of follow-up observation ranged from 1 week to 72 months. Results: Two cases were normal on mammograms. High proportion of abnormal mammography was seen in the period of 12 month (40.3%, 56/139) and 24 month (21.6%, 30/139), respectively. Various findings appeared in various periods and the difference was statistically significant(X 2 =30.998, v=6, P=0.001). Mild edema appeared in the first 3 years. Moderately severe or marked breast edema may be present between 6 months to 12 months, then slowly resolved. The appearance and disappearance of skin thickening were similar to the process of breast edema. The changes of architectural disturbance did not correlate with time (X 2 =8.634, P>0.05), but on sequential mammograms for same patient, the extent of architectural disturbance relieved over time (17/19). Asymmetric density was found in only 5 patients, and disappeared in later period of follow-up in 3. Architectural distortion retraction got more and more obvious with time, and kept stable after certain period of time. Calcifications were shown in 2 patients, including 1

    Objective To evaluate multi-slice three-dimensional CT angiography (MS 3D-CTA) for the follow-up of intracranial aneurysm clipping. Methods: MS 3D-CTA of 16 patients with intracranial aneurysm clipping were retrospectively analyzed. The patients were scanned on a 16-slice spiral CT (GE Lightspeed pro). Volume rendering(VR), thin maximum intensity projection(thin MIP) and multi-planar reconstruction (MPR) were employed in image postprocessing in all cases. Results: There were 17 clips in the 16 patients with aneurysm clipping. Six clips were located at the posterior communicating artery, 5 at the anterior communicating artery, 4 at the middle cerebral artery, and the remaining 2 clips were located at the pericallosal artery, in 1 patient. There were no abnormalities found in the aneurysm clipping region in 7 cases by MS 3D- CTA. There were residual aneurysm in 2 cases, parent artery stenosis in 4 cases, and artery spasm in 3 eases. There was no parent artery occlusion and clip displacement in all cases. VR showed excellent 3D spacial relations between the clip and parent artery in 12 cases, and showed good relations in 3 cases. The 1 case with 2 clips in the pericallosal artery showed heavy beam-hardening artifacts. The size and shape of aneurysm clips were clearly depicted by MPR and thin MIP, while 3D spacial relation of aneurysm clip and parent artery were poorly showed. Conclusion: MS 3D-CTA is a safe and efficient method for the follow-up of intracranialaneurysm clipping. Combined VR with MPR or thin MIP can well reveal postoperative changes after aneurysm clipping. (authors)

    Abdominal ultrasonography is the procedure of choice to diagnose hydatid cysts caused by Echinococcus granulosus. Recently three-dimensional ultrasonography has become available for clinical application. We report a case of an atypical seronegative hydatid disease, in which the additional use of 3D-sonography improved the sonographic diagnosis, which was confirmed by a fine needle biopsie complicated by an anaphylactic reaction. In addition the potential advantage of 3D-ultrasonography in diagnosis and follow-up hydatid disease will be discussed, especially in the context of new alternative therapeutic options like chemotherapy with benzimidazoles or the percutaneous drainage by the PAIR procedure (puncture-aspiration-injection-re-aspiration).

    Secondary bone fracture heating was analysed by scintigraphic follow-up studies in rabbits using sup(99m)Tc-HEDP. 24 hours after fracture the activity ratio between the fractured and the non-fractured lower limb was 2,2. The maximal count density in the fracture region is found during the 14th and 28th day after fracture. Concomitantly there is a significant increase of bone marrow vessels and content of copper, magnesium, sodium and water in the callus. Although roentgenographic controls and static investigations with respect to consolidation reveal a complete heating already 126 days after fracture, the complete scintigraphic normalisation of the lower limb fracture of the rabbit is found not earlier than at the 203rd day after fracture.

    The authors conducted a follow-up study on 243 Thorotrast-administered war-wounded ex-servicemen in 1975, after a lapse of 30 to 38 years from Thorotrast injections, and found 18 cases of malignant hepatic tumor, 15 cases of other malignant tumors, 2 cases of blood diseases, and 9 cases of liver cirrhosis in 224 cases who had been given Thorotrast intravascularly. The incidence of hepatic and other malignant tumors, blood diseases, and liver cirrhosis was significantly higher than in the controls. The total number of deaths in the Thorotrast-administered cases was also significantly higher than in the controls. In the remaining 19 cases who had been given Thorotrast by a route other than intravascularly, no fatal case related to Thorotrast administration was discovered. In the living cases, however, one sarcoma was observed to have developed at the site of the Thorotrast injection

    Patients with neuromuscular disease are an important group at risk of frequently suffering acute or chronic respiratory failure, which is their main cause of death. They require follow-up by a pediatric respiratory medicine specialist from birth or diagnosis in order to confirm the diagnosis and treat any respiratory complications within a multidisciplinary context. The ventilatory support and the cough assistance have improved the quality of life and long-term survival for many of these patients. In this paper, the authors review the pathophysiology, respiratory function evaluation, sleep disorders, and the most frequent respiratory complications in neuromuscular diseases. The various treatments used, from a respiratory medicine point of view, will be analyzed in a next paper. Copyright © 2013 Asociación Española de Pediatría. Published by Elsevier Espana.

    1975-01-01

    Whilst the medical indications for therapeutic abortion and the legal limitations set vary enormously from one country to another there is in general an undoubted trend towards giving the pregnant woman herself a greater say in the decision. During the first year of the operation of the Abortion Act, 1967, in England some 72 pregnant women were referred to the author and his colleagues for a recommendation on abortion. A psychiatric examination and follow-up over a period of one year was made both in those cases where abortion was performed as well as in those cases who were refused therapeutic abortion. In this communication a comparison is made between the reactions and outcome in the two groups. A provisional conclusion is reached that no significant psychiatric disturbance could be attributed to the performance of the operation or on the other hand to refusal of the woman's request.

    Vertebral involvement in sarcoidosis is rare and its clinical and imaging features are non-specific. Indeed, because the lesions are hard to differentiate from metastatic disease based on imaging alone, a histological confirmation is advised. Fatty replacement is a well-known finding indicating stabilization and healing in both benign and malignant conditions. It can be used as an indicator of a favorable disease course and response to treatment. We report the case of a 43-year-old woman with multifocal vertebral sarcoidosis lesions and long-term follow-up showing progressive and gradual fatty involution on magnetic resonance imaging (MRI) during 4 years of steroid treatment with a final favorable outcome.

    The study evaluated the subjective functional outcome following total knee arthroplasty (TKA) in participants who underwent hydrotherapy (HT) six months after discharge from a rehabilitation unit. A total of 70 subjects, 12 of which were lost at follow-up, were randomly assigned to either a conventional gym treatment (N=30) or HT (N=28). A prospective design was performed. Participants were interviewed with Western-Ontario McMasters Universities Osteoarthritis Index (WOMAC) at admission, at discharge and six months later. Kruskal-Wallis and Wilcoxon tests were applied for statistical analysis. Both groups improved. The WOMAC subscales, namely pain, stiffness and function, were all positively affected. Statistical analysis indicates that scores on all subscales were significantly lower for the HT group. The benefits gained by the time of discharge were still found after six months. HT is recommended after TKA in a geriatric population. Copyright 2009 Elsevier Ireland Ltd. All rights reserved.

    The study aimed to evaluate the morphologic changes in transarterial chemoembolization (TACE) puncture sites implanted with an ExoSeal vascular closure device (VCD) using follow-up computed tomography (CT). 16 patients who used ExoSeal VCD after TACE were enrolled. Using CT images, the diameters and anterior wall thicknesses of the puncture sites in the common femoral artery (CFA) were compared with those of the contralateral CFA before TACE, at 1 month after every TACE session, and at the final follow-up period. The rates of complications were also evaluated. There were no puncture- or VCD-related complications. Follow-up CT images of the CFA's of patients who used ExoSeal VCDs showed eccentric vascular wall thickening with soft-tissue densities considered to be hemostatic plugs. Final follow-up CT images (mean, 616 days; range, 95–1106 days) revealed partial or complete resorption of the hemostatic plugs. The CFA puncture site diameters did not differ statistically from those of the contralateral CFA on the final follow-up CT (p > 0.05), regardless of the number of VCDs used. Follow-up CT images of patients who used ExoSeal VCDs showed no significant vascular stenosis or significant vessel wall thickening

    Magnetic resonance imaging (MRI) is frequently performed during follow-up in patients with known lumbar-disk herniation and persistent symptoms of sciatica. The association between findings on MRI and clinical outcome is controversial. We studied 283 patients in a randomized trial comparing surgery and prolonged conservative care for sciatica and lumbar-disk herniation. Patients underwent MRI at baseline and after 1 year. We used a 4-point scale to assess disk herniation on MRI, ranging from 1 for "definitely present" to 4 for "definitely absent." A favorable clinical outcome was defined as complete or nearly complete disappearance of symptoms at 1 year. We compared proportions of patients with a favorable outcome among those with a definite absence of disk herniation and those with a definite, probable, or possible presence of disk herniation at 1 year. The area under the receiver-operating-characteristic (ROC) curve was used to assess the prognostic accuracy of the 4-point scores regarding a favorable or unfavorable outcome, with 1 indicating perfect discriminatory value and 0.5 or less indicating no discriminatory value. At 1 year, 84% of the patients reported having a favorable outcome. Disk herniation was visible in 35% with a favorable outcome and in 33% with an unfavorable outcome (P=0.70). A favorable outcome was reported in 85% of patients with disk herniation and 83% without disk herniation (P=0.70). MRI assessment of disk herniation did not distinguish between patients with a favorable outcome and those with an unfavorable outcome (area under ROC curve, 0.48). MRI performed at 1-year follow-up in patients who had been treated for sciatica and lumbar-disk herniation did not distinguish between those with a favorable outcome and those with an unfavorable outcome.

    We have used the Caltech Submillimeter Observatory (CSO) to follow-up a sample of Wide-field Infrared Survey Explorer (WISE) selected, hyperluminous galaxies, the so-called W1W2-dropout galaxies. This is a rare (∼1000 all-sky) population of galaxies at high redshift (peaks at z = 2-3), which are faint or undetected by WISE at 3.4 and 4.6 μm, yet are clearly detected at 12 and 22 μm. The optical spectra of most of these galaxies show significant active galactic nucleus activity. We observed 14 high-redshift (z > 1.7) W1W2-dropout galaxies with SHARC-II at 350-850 μm, with nine detections, and observed 18 with Bolocam at 1.1 mm, with five detections. Warm Spitzer follow-up of 25 targets at 3.6 and 4.5 μm, as well as optical spectra of 12 targets, are also presented in the paper. Combining WISE data with observations from warm Spitzer and CSO, we constructed their mid-IR to millimeter spectral energy distributions (SEDs). These SEDs have a consistent shape, showing significantly higher mid-IR to submillimeter ratios than other galaxy templates, suggesting a hotter dust temperature. We estimate their dust temperatures to be 60-120 K using a single-temperature model. Their infrared luminosities are well over 10 13 L ☉ . These SEDs are not well fitted with existing galaxy templates, suggesting they are a new population with very high luminosity and hot dust. They are likely among the most luminous galaxies in the universe. We argue that they are extreme cases of luminous, hot dust-obscured galaxies (DOGs), possibly representing a short evolutionary phase during galaxy merging and evolution. A better understanding of their long-wavelength properties needs ALMA as well as Herschel data.

    We have used the Caltech Submillimeter Observatory (CSO) to follow-up a sample of Wide-field Infrared Survey Explorer (WISE) selected, hyperluminous galaxies, the so-called W1W2-dropout galaxies. This is a rare (approximately 1000 all-sky) population of galaxies at high redshift (peaks at zeta = 2-3), which are faint or undetected by WISE at 3.4 and 4.6 micrometers, yet are clearly detected at 12 and 22 micrometers. The optical spectra of most of these galaxies show significant active galactic nucleus activity. We observed 14 high-redshift (zeta greater than 1.7) W1W2-dropout galaxies with SHARC-II at 350-850 micrometers, with nine detections, and observed 18 with Bolocam at 1.1 mm, with five detections.

    Full Text Available Hydronephrosis is probably the most common congenital abnormality detected prenatally by ultrasonography This study was performed to determine the cause and outcome of prenatal hydronephrosis in our hospital. A total of 45 infants, with 57 prenatally hydronephrotic renal units, were enrolled into this study. For the purpose of this study, the degree of hydronephrosis was defined as mild, moderate or severe. Postnatal ultrasonography was performed as soon as possible in those with bilateral hyronephrosis and 3-7 days after birth in those with unilateral hydronephrosis. Voiding cystourethrogram was performed in 6-8 weeks time. In the absence of vesicoureteral reflux (VUR, Diethylenetriamene penta acetate scan was performed to exclude obstructive uropathy. There were 29 males and 16 females (male:female ratio 1.8:1, and unilateral and bilateral hydronephrosis were seen in 33 (73% and 12 (27% of the cases, res-pectively. Hydronephrosis was caused by ureteropelvic junction obstruction (UPJO in 20 (44.5%, VUR in 10 (22.2%, ureterovesical junction obstruction in four (8.9 %, posteriorurethral valves in four (8.9 %, UPJO with VUR in two (4.4% and non-VUR non-obstructive in one (2.2%. During follow-up, 16 patients (35.5% required operative intervention while seven (15.5% improved spontaneously. Fetal hydronephrosis needs close follow-up during both ante-natal and postnatal periods. In this study, the most common cause for hydronephrosis were UPJO and VUR. Also seen in this study is the noteworthy point that mild fetal hydronephrosis is relatively benign and does not require surgical intervention in most cases and surgery should be performed only if there is renal function compromise. Prenatal consultation with a pediatric nephrologist and urologist is useful in decreasing parental anxiety and facilitating postnatal management.

    1. Out of 67 patients ranging from 16 to 82 years old, 20 were followed up by CT scan after operation. 2. Five patients presented hematoma on the both sides after operation, though they had suffered from the lesion of one side before operation. In four patients, hematoma was observed on the both sides before and after operation. Neither preoperative involved side changed nor hematoma appeared on the opposite side after operation in 11 patients. Follow-up examinations lasted up almost three months. 3. The maximum width of the subdural space was divided by the maximum intracranial width. These two factors were measured on horizontal CT scan. The calculated value was expressed in percentage and then, the result was regarded as Subdural Space (SDS) Index. Dividing a difference between the largest SDS Index (before operation) and the smallest by the number of days between the two points gave us a reduction rate of SDS Index. As a result, a reduction rate of 0.4 or less was obtained in all the patients less than 65 years old. There were three patients within the range from 0.7 to 1.0 of the rate. 76-year-old patients showed 2.6 and 5.7. Except the 76-old patients, mean duration of 35.5 days was calculated in Group I and SDS Index was 0, while Group II showed mean duration of 52.4 days, resulting in SDS Index of 0. 4. Specific progresses are shown below: 1) Hemorrhage of the caudate nucleus after operation 2) Subdural effusion of the both sides 3) Appearance of abscess 4) Subtentrial hemorrhage after operation 5) Postoperative epidural hematoma 6) Traumatic intracerebral hemorrhage, resulting in chronic subdural hematoma six months afterward (author)

    In 66 patients the relationship between lung volumes and lung mechanics in pulmonary sarcoidosis was investigated. Lung volumes, static lung mechanics, lung resistance, dynamic lung mechanics and arterial blood gases at rest and during exercise were obtained. Fifteen functionally compromised patients received steroids during one year. They were re-investigated during the treatment and at a follow-up after an average of 7 years. In another 41 patients with newly diagnosed sarcoidosis, the kinetics of the lung clearance of 99m Tc-DTPA measured over 180 minutes was explored, and compared to kinetics in healthy smokers. The relationship between lung clearance and lung volumes, lung mechanics, arterial blood gases and disease activity assessed with serum angiotensin-converting enzyme and 67 Ga scintigraphy was studied. Reducing lung volumes and compliance, increased resistance and arterial oxygen tension were common. Vital capacity (VC), and changes of VC at follow-up, corresponded to the slope of the static elastic pressure/volume curve, and to the variation of it. Other static lung volumes reflected rather the position of the curve along the volume axis. Reduced VC also reflected obstruction. Forced expiratory volume in one second revealed to equal extent lung stiffness and obstruction. Lung mechanics showed abnormalities not always evident from spirometry.In 50% of the patients lung clearance of 99m Tc-DTPA disclosed an abnormally fast mono-exponential clearance or a bi-exponential clearance, which however differed from that in smokers. Lung clearance more readily detected abnormal function than did spirometry. Clearance did nor correlate with other investigations. 67 Ga lung activity was higher in patients with a pathologic lung clearance

    To study the long-term risk of recurrent cardiac, arterial, and venous events in young stroke patients, and whether these risks differed between etiologic subgroups. The study population comprised 970 patients aged 15-49 years from the Helsinki Young Stroke Registry (HYSR) who had an ischemic stroke in 1994-2007. We obtained follow-up data until 2012 from the Finnish Care Register and Statistics Finland. Cumulative 15-year risks were analyzed with life tables, whereas relative risks and corresponding confidence intervals (CI) were based on hazard ratios (HR) from Cox regression analyses. There were 283 (29.2%) patients with a cardiovascular event during the median follow-up of 10.1 years (range 0.1-18.0). Cumulative 15-year risk for venous events was 3.9%. Cumulative 15-year incidence rate for composite vascular events was 34.0 (95% CI 30.1-38.2) per 1,000 person-years. When adjusted for age and sex, patients with an index stroke caused by high-risk sources of cardioembolism had the highest HR for any subsequent cardiovascular events (3.7; 95% CI 2.6-5.4), whereas the large-artery atherosclerosis group had the highest HR (2.7; 95% CI 1.6-4.6) for recurrent stroke compared with patients with stroke of undetermined etiology. The risk for future cardiovascular events after ischemic stroke in young adults remains high for years after the index stroke, in particular when the index stroke is caused by high-risk sources of cardioembolism or large-artery atherosclerosis. © 2016 American Academy of Neurology.

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

    The goal of this study was to estimate the ovarian dose and entrance skin dose (ESD) of patients who underwent uterine artery embolization (UAE) procedure. To achieve this, 49 UAE procedures were accompanied where the parameters of image acquisition were recorded for the calculation of the DEP from the output of the X-ray tube. The estimation of the ovarian dose was carried out by the insertion of a vaginal probe containing 3 TLD's. The obtained values were compared with the results of other authors and a higher value of ovarian dose (28,97 cGy) and ESD (403,57 cGy) was found in this work. Analysis of the results allowed to observe that this result was obtained mainly as a result of the high number of arteriography series and the frames/second rates employed. Following on from these observations, the protocol of EMUT was altered reducing the frames/seg rate from 2 to 1. Efforts with a view to reducing the number of arteriography series also became part of the next proceedings. (author)

    The purpose of this study was to evaluate the clinical results, complications, and secondary interventions during long-term follow-up after endovascular aneurysm repair (EVAR) and to investigate the impact of endoleak sizes on aneurysm shrinkage. From 1997 to March 2007, 127 patients (12 female, 115 male; age, 73.0 ± 7.2 years) with abdominal aortic aneurysms were treated with Talent stent-grafts. Follow-up included clinical visits, contrast-enhanced MDCT, and radiographs at 3, 6, and 12 months and then annually. Results were analyzed with respect to clinical outcome, secondary interventions, endoleak rate and management, and change in aneurysm size. There was no need for primary conversion surgery. Thirty-day mortality was 1.6% (two myocardial infarctions). Procedure-related morbidity was 2.4% (paraplegia, partial infarction of one kidney, and inguinal bleeding requiring surgery). Mean follow-up was 47.7 ± 34.2 months (range, 0-123 months). Thirty-nine patients died during follow-up; three of the deaths were related to aneurysm (aneurysm rupture due to endoleak, n = 1; secondary surgical reintervention n = 2). During follow-up, a total of 29 secondary procedures were performed in 19 patients, including 14 percutaneous procedures (10 patients) and 15 surgical procedures (12 patients), including 4 cases with late conversion to open aortic repair (stent-graft infection, n = 1; migration, endoleak, or endotension, n = 3). Overall mean survival was 84.5 ± 4.7 months. Mean survival and freedom from any event was 66.7 ± 4.5 months. MRI depicted significantly more endoleaks compared to MDCT (23.5% vs. 14.3%; P 10% of the aneurysm area were associated with reduced aneurysm shrinkage compared to no endoleaks or <10% endoleaks (Δ at 3 years, -1.8% vs. -12.0%; P < 0.05). In conclusion, endovascular aneurysm treatment with Talent stent-grafts demonstrated encouraging long-term results with moderate secondary intervention rates. Primary occlusion of all aortic side

Thus, accurately identifying depression in CAD patients is imperative. In many veterans affairs (VA hospitals, patients are screened for depression once a year using the patient health questionnaire (PHQ-9. Although the PHQ-9 is generally considered a specific and sensitive measure of depression, there is reason to believe that these screening procedures may miss a large number of cases of depression within CAD patients and cardiology patients more generally. The goal of this study was to provide data as to the predictive power of this depression screening procedure by (a comparing the prevalence rate of depression identified by the PHQ-9 to known prevalence rates and (b examining whether patients identified as “depressed” also had conditions that consistently co-occur with depression (eg, post-traumatic stress disorder [PTSD], other medical issues. Participants were 813 consecutive patients who received an angiogram in the cardiac catheterization laboratory at a large VA Medical Center. Prevalence of depression was 6.9% in the overall sample and less than 6% when the sample was restricted to CAD patients with significant stenosis. Depression was significantly associated with PTSD, smoking, and alcohol problems. However, depression was not associated with other medical problems such as diabetes, renal failure, peripheral vascular disease, or anemia. In conclusion, the low prevalence rate of depression and lack of associations with comorbid medical problems may suggest that the VA’s depression screening procedures have low sensitivity for identifying depression in CAD

    Elastic follow-up (EFU) is a complex phenomenon which affects the behaviour of some structural components, especially in high temperature operations. One of the major problems encountered by the designer is the quantitative evaluation of the amount of elastic follow-up that must be taken into account for the structures under examination. In the present paper a review of the guidance furnished by the ASME Code regarding EFU is presented through an application concerning a structural problem in which EFU occurs. This has been carried out with the additional purpose of comparing the percentage EFU obtained by two simplified methods: an inelastic simplified method involving relaxation analysis; the reduced elastic modulus procedure generally used for EFU problems in piping systems. The results obtained demonstrate a substantial agreement between the two methodologies when applied to a general type structure. (author)

    Attempts are now being made to address the historic marginalization of indigenous peoples from the management of resource projects located on their ancestral lands through the use of environmental agreements. However, the rapid pace of resource development in certain regions of Canada has meant that there is an increased need to ensure effective follow-up procedures for Environmental Impact Assessment (EIA) processes in order to achieve meaningful Aboriginal participation in the management of large-scale resource projects. Lack of effective follow-up has made it difficult for the relevant agencies to manage risks and uncertainties. This book discussed the use of new policy environmental agreements between industry, government, and Aboriginal peoples. Case studies where environmental agreements were used in the Northwest Territories, Alberta, and Newfoundland were presented in order to demonstrate their efficacy. It was concluded that structures and processes must be designed to encourage Aboriginal participation in consultation processes. refs., tabs.

    Purpose: To examine the costs and benefits of an established practice of routine follow-up in a cohort of patients treated with radiation therapy for early stage Hodgkin's disease. Materials and Methods: We retrospectively examined patterns of follow-up and methods of relapse detection among 709 patients with Ann Arbor Stage I-II Hodgkin's disease treated with sub-total lymphoid irradiation (STLI) or total lymphoid irradiation (TLI) between 1969-1994. We determined the probability of relapse detection for each of 7 routine follow up procedures, compared their relative costs, and determined the impact of each procedure on the likelihood of overall survival following salvage therapy. Results: Relapse has occurred in 157 patients (22%) at a median 1.9 years (range 0-13 years) following treatment. 133 relapses (85%) occurred during the first 5 years of follow. Detailed information concerning the method of relapse detection was available on 107 patients. These 107 patients form the basis of this analysis. Relapse was identified by history (Hx) alone in 55% of patients, physical exam (PE) in 14%, chest x-ray (CXR) in 23% and abdominal x-ray (KUB) in 7%. Only one relapse (1%) was identified by a routine laboratory study - erythrocyte sedimentation rate (ESR). The rate of relapse detection was highest for a combination of history and physical exam (78/10,000 exams) followed by CXR (26/10,000 exams), KUB (10/10,000 exams) and ESR (1/10,000 tests). Complete blood count (CBC) and serum chemistries were never the primary factor in detecting HD relapse. Radiographs accounted for greater than 60% of charges while laboratory studies and physician charges accounted for approximately 20% each. The projected charges (1994 dollars) of relapse detection by routine follow up Hx and PE was [dollar]10,600 compared with [dollar]68,200 for CXR, [dollar]141,800 for KUB and [dollar]156,400 for ESR. 10 year actuarial survival following salvage therapy was 65% overall, 65% for patients in whom

    The purpose of this study was to evaluate the technical success, complications, long-term clinical outcome, and patency after primary infrarenal aortic stenting for aortic and aortoiliac stenosis. Between January 1999 and January 2006, 22 consecutive patients underwent endovascular treatment because of infrarenal aortic stenosis with and without common iliac stenosis (10 men; mean age 64 ± 14 years). Eleven (11 of 22) patients had an isolated aortic stenosis, whereas 11 of 22 had aortic stenosis that extended into the common iliac arteries (CIAs). Thirteen patients were Rutherford classification type 3, and 9 patients were type 4. Statistical analysis included paired Student t test and Kaplan–Meier life table analysis; p < 0.05 was considered significant. Technical and initial clinical success was achieved in all patients. There were three (14 %) procedure-related complications, which included two access-point pseudoaneurysms and one non–flow-limiting left external iliac dissection. Patients were followed-up for a mean period of 88 months (range 60–132). Mean preprocedure ankle brachial pressure indexes (ABPI) were 0.60 ± −0.15 (right) and 0.61 ± −0.16 (left). After the procedure they were 0.86 ± −0.07 (right) and 0.90 ± −0.09 (left). The increase in ABPI was significant (p < 0.05), and this continued throughout follow-up. Four (18 %) patients had recurrence of symptoms during follow-up. These occurred at 36, 48, 48, and 50 months after the original procedure. All four patients were successfully treated with repeat angioplasty procedures. There was a significant difference in primary patency between isolated aortic stenosis (100 %) and aortoiliac stenosis (60 %) (p = 0.031). Cumulative follow-up was 1920 months yielding a reintervention rate of 0.025/events/year. Primary stenting of infrarenal stenosis is safe and successful with a low reintervention rate. It should be considered as first-line treatment for patients with infrarenal aortic

    Objective: To retrospectively evaluate the cerebrovascular complications from stenting for symptomatic intracranial stenosis and to detect the factors associated with complications. Methods: Medical records of Wingspan stenting were reviewed for 306 cases with symptomatic intracranial stenosis from July 2007 to February 2012, including transient ischemic attack, ischemic stroke, death and intracranial hemorrhage as clinical in-hospital complications. The location of lesions included middle cerebral artery level M1 (114 lesions), intracranial portion of the internal carotid artery (50 lesions), vertebral artery 4 (75 lesions), venebro-basilar artery (14 lesions), basilar artery (76 lesions). Complications were evaluated and analyzed to find out whether they were associated with patient-or stenosis-related risk factors using χ"2 test. Results: The technical success rate was 99% (303/306). Cerebrovascular complications rate was 6.9% (21/303), with 1.6% (14/303) of disabling stroke events and 0.7% (2/303) of deaths. Hemorrhagic events were consisted of procedure-related events (3 cases), hyperperfusion (3 cases), ischemic events of perforator stroke (8 cases), transient ischemic attack (3 cases), embolization (2 cases), thrombosis in stent (2 cases). Hemorrhagic events were associated with significantly higher morbidity and mortality rates (χ"2 = 2.908, P < 0.05) and occurred more frequently after treatment of middle cerebral artery stenosis than other lesions (χ"2 = 1.168, P < 0.05). Perforating branches were detected to be affected mainly in the basilar artery than other locations (χ"2 = 4.263, P < 0.05). Conclusion: The complication rates in the study are preliminary consistent with the previously published data. Hemorrhagic events are prone to occur in the treatment of middle cerebral artery stenosis, while perforating branches are affected mainly in the basilar artery. (authors)

    To examine the progression pattern of myopic maculopathy. Retrospective, observational case series. Highly myopic patients who had been followed up for 10 years or more. Using fundus photographs, myopic features were differentiated according to Meta-analysis of Pathologic Myopia (META-PM) Study Group recommendations. Progression pattern of maculopathy. The study included 810 eyes of 432 patients (mean age, 42.3±16.8 years; mean axial length, 28.8±1.9 mm; mean follow-up, 18.7±7.1 years). The progression rate of myopic maculopathy was 47.0 per 1000 eye-years. Within the pathologic myopia (PM) group (n = 521 eyes), progression of myopic maculopathy was associated with female gender (odds ratio [OR], 2.21; P = 0.001), older age (OR, 1.03; P = 0.002), longer axial length (OR, 1.20; P = 0.007), greater axial elongation (OR, 1.45; P = 0.005), and development of parapapillary atrophy (PPA; OR, 3.14; P < 0.001). Diffuse atrophy, found in 217 eyes without choroidal neovascularization (CNV) or lacquer cracks (LCs) at baseline, progressed in 111 (51%) eyes, leading to macular diffuse atrophy (n = 64; 64/111 or 58%), patchy atrophy (n = 59; 53%), myopic CNV (n = 18; 16%), LCs (n = 9; 5%), and patchy-related macular atrophy (n = 3; 3%). Patchy atrophy, detected in 63 eyes without CNV or LCs at baseline, showed progression in 60 eyes (95%), leading to enlargement of original patchy atrophy (n = 59; 59/60 or 98%), new patchy atrophy (n = 29; 48%), CNV-related macular atrophy (n = 13; 22%), and patchy-related macular atrophy (n = 5; 8%). Of 66 eyes with LCs, 43 eyes (65%) showed progression with development of new patchy atrophy (n = 38; 38/43 or 88%) and new LCs (n = 7; 16%). Reduction in best-corrected visual acuity (BCVA) was associated mainly (all P < 0.001) with the development of CNV or CNV-related macular atrophy and enlargement of macular atrophy. The most frequent progression patterns were an extension of peripapillary diffuse atrophy to macular diffuse

    This paper reports the activities and the results of the research carried out by the Centers participating to the JSP4 project, within the framework of the EU program on the consequences of the Chernobyl disaster. The project was aimed to develop and to control the application of basic principles for the diagnosis, treatment and follow-up of thyroid carcinoma, with special attention to the peculiar requirement of children and adolescents. To this purpose, training in Western European Centers was offered to a number of scientists from Belarus, Ukraine and Russia. Several official meetings were organized to share views and to discuss the progress of the project. A basic protocol for the diagnosis, treatment and follow-up of thyroid carcinoma has been developed and approved by all participating Centers. Hopefully, it will be applied to the new cases and to those already under monitoring. A large part of the protocol is dedicated to the post-surgical treatment with thyroid hormones for the suppression of TSH and with calcitriol for the management of surgical hypoparathyroidism. A detailed protocol to asses iodine deficiency and, eventually, to introduce a program of iodine supplementation has been proposed. The collection of control cases of childhood thyroid carcinoma in non-radiation exposed European countries has been initiated in Italy, France and Germany. This data will be used as control for the post-Chernobyl childhood thyroid carcinomas. Here is reported a preliminary comparison of the clinical and epidemiological features of almost all (n=368) radiation-exposed Belarus children who developed thyroid carcinoma (age at diagnosis < 16 years), with respect to 90 children of the same age group, who, in the past 20 years, have received treatment for thyroid carcinoma in two centers in Italy (Pisa and Rome). Finally, by molecular biology, genetic mutations of the RET proto-oncogene have been found in several samples of thyroid carcinomas provided by the Belarus

    Objective: To evaluate the feasibility and safety of combined uterine artery embolization (UAE) using embosphere and surgical myomectomy as an alternative to radical hysterectomy in premenopausal women with multiple fibroids. Materials and methods: Mid-term clinical outcome (mean, 25 months) of 12 premenopausal women (mean age, 38 years) with multiple and large symptomatic fibroids who desired to retain their uterus and who were treated using combined UAE and surgical myomectomy were retrospectively analyzed. In all women, UAE alone was contraindicated because of large (>10 cm) or subserosal or submucosal fibroids and myomectomy alone was contraindicated because of too many (>10) fibroids. Results: UAE and surgical myomectomy were successfully performed in all women. Myomectomy was performed using laparoscopy (n = 6), open laparotomy (n = 3), hysteroscopy (n = 2), or laparoscopy and hysteroscopy (n = 1). Mean serum hemoglobin level drop was 0.97 g/dL and no blood transfusion was needed. No immediate complications were observed and all women reported resumption of normal menses. During a mean follow-up period of 25 months (range, 14–37 months), complete resolution of initial symptoms along with decrease in uterine volume (mean, 48%) was observed in all women. No further hysterectomy was required in any woman. Conclusion: In premenopausal women with multiple fibroids, the two-step procedure is safe and effective alternative to radical hysterectomy, which allows preserving the uterus. Further prospective studies, however, should be done to determine the actual benefit of this combined approach on the incidence of subsequent pregnancies.

    Long-term results regarding treatment of chronic ischemic heart failure with bone marrow mononuclear cells (BMMCs) have been few. We received encouraging results at the 1-year follow-up of patients treated with combined coronary artery bypass grafting (CABG) and BMMCs, so we decided to extend the follow-up. The study patients had received injections of BMMCs or vehicle into the myocardial infarction border area during CABG in a randomized and double-blind manner. We could contact 36 of the 39 patients recruited for the original study. Pre-operatively and after an extended follow-up period, we performed magnetic resonance imaging, measured pro-B-type amino-terminal natriuretic peptide, reviewed patient records from the follow-up period, and determined current quality of life with the Medical Outcomes Study Short-Form 36 (SF-36) Health Survey. The median follow-up time was 60.7 months (interquartile range [IQR], 45.1-72.6 months). No statistically significant difference was detected in change of pro-B-type amino-terminal natriuretic peptide values or in quality of life between groups. The median change in left ventricular ejection fraction was 4.9% (IQR, -2.1% to 12.3%) for controls and 3.9% (IQR, -5.2% to 10.2%) for the BMMC group (p = 0.647). Wall thickening in injected segments increased by a median of 17% (IQR, -5% to 30%) for controls and 15% (IQR, -12% to 19%) for BMMC patients (p = 0.434). Scar size in injected segments increased by a median of 2% (IQR, -7% to 19%) for controls but diminished for BMMC patients, with a median change of -17% (IQR, -30% to -6%; p = 0.011). In the treatment of chronic ischemic heart failure, combining intramyocardial BMMC therapy with CABG fails to affect cardiac function but can sustainably reduce scar size, even in the long-term.

    Before the introduction of the tension-free vaginal tape (TVT) procedure for the treatment of female stress urinary incontinence, the colposuspension operation was regarded as the "gold standard" procedure. The laparoscopic variant of the colposuspension was introduced as a less invasive operation. The aim of the present trial was to compare the new minimally invasive TVT procedure with laparoscopic mesh colposuspension (LCM). A multicenter randomized clinical trial conducted in six public hospitals in Finland including primary cases of stress incontinence. Objective treatment success criteria were a negative stress test and no retreatment for stress incontinence. Patient satisfaction was assessed by Patients Global Impression of Improvement, a visual analog scale, and the Urinary Incontinence Severity Score. Of 128 randomized patients, 121 underwent the allocated operation. At the 5-year follow-up 77 % in the TVT group and 84 % in the LCM group could be assessed according to the protocol. The objective cure rate was significantly higher in the TVT group (94 %) than in the LCM group (78 %). Subjective treatment satisfaction (completely satisfied with the procedure) was significantly higher in the TVT group (64 %) than in the LCM group (51 %). By per protocol analysis both objective and subjective cure rates were significantly higher in the TVT group than in the LCM group. If cases that were lost to follow-up were regarded as failures, the intension-to-treat analysis found no difference between the groups.

    Anterior craniofacial duplication (diprosopus) is an extremely rare form of conjoined twins. The children share a single trunk with normal extremities and varying degrees of facial malformation. Duplication of specific structures, such as the nose (diprosopus dirrhinus), eyes (diprosopus tetraophthalmus), and ears, is possible. The authors present a case of partial facial duplication (diprosopus dirrhinus) in a male infant. The clinical and radiographic findings and the surgical correction and follow-up are described. In a single surgical session, the authors were able to achieve not only a functionally but also an aesthetically acceptable result. In the postoperative course, the child showed nearly normal growth and satisfactory psychosocial and motor development. However, 40 months postoperatively, we noticed a tendency of the orbitae to diverge (i.e., toward hypertelorism). The surgical management of complex craniofacial malformations such as diprosopus needs a precise morphologic analysis of the patient's deformity followed by a clear treatment plan. A staged reconstructive approach is carried out to coincide with facial growth patterns and brain and eye function. If the interorbital distance in our patient increases progressively, a second operation for reduction of the interorbital distance may be necessary.

    Despite a better management of the variables that influence the development of diabetic nephropathy there is a progressive increase in the prevalence of terminal renal failure among diabetics, whose cause is not clear. To study in a group of patients in hemodialysis, the quality of diabetes control previous to the entry to dialysis, their physical condition and their evolution. Diabetic patients with at least three months of hemodialysis answered a questionnaire about diabetes control quality previous to dialysis and had physical and laboratory assessment. They were followed for at least four years thereafter. Fifty seven patients aged 62+/-11 years were studied. Eighty four percent had some degree of disability. Eighty seven percent had high blood pressure and 73% had to enter dialysis as an emergency. Mean glycosilated hemoglobin was 7.7% and 58% had a dialysis dose with a Kt/Vofless than 1.2. Fifty eight percent died during follow up. No relationship between mortality and age, blood pressure, glycosilated hemoglobin of Kt/V, was observed. There is an inadequate management of blood glucose and blood pressure of diabetic patients before entry to dialysis. They are referred inverted exclamation markate to the nephrologist, the dialysis dose is insufficient and they have a high mortality.

    Planetary systems, discovered by the radial velocity (RV) surveys, reveal strong correlations between the planet frequency and stellar properties, such as metallicity and mass, and a greater diversity in planets than found in the solar system. However, due to the sample sizes of extant surveys (~100 to a few hundreds of stars) and their heterogeneity, many key questions remained to be addressed: Do metal poor stars obey the same trends for planet occurrence as metal rich stars? What is the distribution of giant planets around intermediate- mass stars and binaries? Is the ``planet desert'' within 0.6 AU in the planet orbital distribution of intermediate-mass stars real? The MARVELS survey has produced the largest homogeneous RV measurements of 3300 V=7.6-12 FGK stars. The latest data pipeline effort at UF has been able to remove long term systematic errors suffered in the earlier data pipeline. 18 high confident giant planet candidates have been identified among newly processed data. We propose to follow up these giant planet candidates with the KPNO EXPERT instrument to confirm the detection and also characterize their orbits. The confirmed planets will be used to measure occurrence rates, distributions and multiplicity of giants planets around F,G,K stars with a broad range of mass (~0.6-2.5 M_⊙) and metallicity ([Fe/H]~-1.5-0.5). The well defined MARVELS survey cadence allows robust determinations of completeness limits for rigorously testing giant planet formation theories and constraining models.

    Objective The aim of this study was to evaluate the results of bilateral sacrospinous fixation (SSF), which was performed with surgical mesh interposition and bilateral vaginal repair. Material and Methods Twenty-two patients underwent SSF between 2010 and 2012, and the results were evaluated retrospectively. The results at preoperative and postoperative 6th, 12th, and 18th months of the pelvic organ prolapse quantification system (POP-Q) and the Pelvic Organ Prolapse/Urinary Incontinence Sexual Questionnaire-12 (PISQ-12) were compared using Friedman and Wilcoxon Signed Ranks tests. Values of p<0.05 and <0.01 were considered statistically significant. Results According to the POP-Q, significant healing was observed on all vaginal vault points (p=0.001), and no prolapse was observed until the 18-month follow-up stage. There were also prominent patients who felt satisfactory with respect to their sexual life according to PISQ-12 (p=0.001). Conclusion This technique appears to provide an adequate clinical resolution, and it may be the primary surgical option for women with pelvic organ prolapse. PMID:26097393

    A retrospective study was performed in 41 patients, in chronic hemodialysis with severe hyperparathyroidism (HPT), who underwent surgery during time period from 1985 to 1997. 22 females, 19 males, aged 50 and 14 years, with PTHI 1345 and 604 pg/ml were followed up 32 and 22 months. Three surgical methods we evaluated: group I) total para thyroidectomy(PTX) with Implants(n=24); group II) subtotal PTX(n=14) and group III) total PTX(n=3). It considered recurrence of HPT when PTH levels were higher than upper range of normal, after 6 months post surgery. persistence was defined when there was no standardization of PTH levels. In group I, 9 patients had normal parathyroid function, 7 had persistent hypoparathyroidism and had hyperparathyroidism (7 recurrences). Group II patients had parathyroid over function in 5 cases (4 persistence s), 5 were normal and 4 hypoparathyroidism. All patients of the third group had hypoparathyroidism. Long term normalization of parathyroid gland activity was achieved in one third of troduccion patients (34,1%) whereas 34,1% permanent hypoparathyroidism and 31,8% hyperparathyroidism. It found no differences in recurrence and histological subtype of parathyroid gland in the different groups. In conclusion, similar long term clinical results were obtained with the different groups. The surgical ideal treatment is controversial. We think that in the long run, the evolution of parathyroid status is mostly influenced by the persistence of uremic state rather than the type of surgery performed [es

    Cytomegalovirus (CMV) is the most common cause of congenital infection affecting about 1% of all the live births worldwide. Its prevalence in the developed world seems to be slightly lower, ranging between 0.6 and 0.7%. Symptoms can be detected at birth in 10-15% of the congenitally infected of which 50-90% will develop sequelae, the most frequent being sensorineural hearing loss (SNHL), visual defect, psychomotor impairment, mental retardation, cerebral palsy and seizures. Eighty-five to 90% of the infected newborns are asymptomatic but 10-15% of them are equally at risk for sensorineural sequelae, like 20-30% of all the infected children. Therefore it is important a time prolonged and closer follow-up of infected children that we propose should be until 6 years of age. This should lead to an early intervention, better management and eventually even control the long-term sequelae. Infants born with symptomatic congenital infection have a worse prognosis than those with no evidence of clinical disease, and ganciclovir (GCV) intravenous 6 mg/kg every 12 h for 6 weeks is the most used therapy for symptomatic newborns. Valganciclovir (V-GCV) syrup is a pro-drug of GCV and presents high oral bioavailability. To date, it is possible to administer this drug at home, and the tolerability profile may allow for wider indications and longer treatments.

  5. Patients’ follow-up using biomechanical analysis of rehabilitation exercises

    Full Text Available Thanks to the evolution of game controllers video games are becoming more and more popular in physical rehabilitation. The integration of serious games in rehabilitation has been tested for various pathologies. Parallel to this clinical research, a lot of studies have been done in order to validate the use of these game controllers for simple biomechanical evaluation. Currently, it is thus possible to record the motions performed by the patients during serious gaming exercises for later analysis. Therefore, data collected during the exercises could be used for monitoring the evolution of the patients during long term rehabilitation. Before using the parameters extracted from the games to assess patients’ evolution two important aspects must be verified: the reproducibility of measurement and a possible effect of learning of the task to be performed. Ten healthy adults played 9 sessions of specific games developed for rehabilitation over a 3-weeks period. Nineteen healthy children played 2 sessions to study the influence of age. Different parameters were extracted from the games: time, range of motion, reaching area. Results of this study indicates that it is possible to follow the evolution of the patients during the rehabilitation process. The majority of the learning effect occurred during the very first session. Therefore, in order to allow proper regular monitoring, the results of this first session should not be included in the follow-up of the patient.

    Bradykinesia is a frequent finding in Huntington's disease (HD), but some aspects are presently unknown; including the natural evolution of bradykinesia over time and the correlation between bradykinesia and functional capacity. We studied the motor performance of 20 genetically confirmed patients with HD (age: 40+/-10.8 years; age at onset 33.6+/-11 years; total functional capacity (TFC): 9.57+/-3; UHDRS total motor scale: 31.4+/-13, triplet length (CAG)n: 46.7+/-4 triplets). These patients were studied in baseline conditions and after 18.7+/-6 months of follow-up. In addition, HD patients were compared with 20 age-matched normal controls. Motor study included the four CAPIT timed tests commonly used for Parkinson's disease: pronation-supination (PS), finger dexterity (FD), movement between two points (MTP) and walking test (WT). HD patients were significantly slower than controls in all motor tasks. A significant deterioration occurred over time in three of the four motor tasks (especially FD and WT). A significant correlation between timed tests and TFC score was found (for MTP, r: -0.845; p < 0,0001). In addition a significant correlation between timed tests and the UHDRDS total motor scale was also found (for MTP, r: 0.864; p < 0.0001). In conclusion, simple timed motor tests can detect a deterioration of motor activity over time in HD. Timed tests might be useful to follow the natural evolution of HD and to assess the efficacy of new therapies.

    In 1964, the Medical Research Council undertook a trial of measles vaccine in over 36,000 United Kingdom children; 9577 of whom received live vaccine, 10,625 received inactivated followed by live vaccines, and 16,328 acted as unvaccinated controls. Participants in this study have been followed to determine the long term protection from measles vaccine and follow-up data were available on 4194, 4638 and 274 respectively. During the 5-year period 1986-90, the protective efficacy of live measles vaccine has remained high at 87%, but the 95% confidence interval was wide (-43 to 99%) due to the small numbers of cases. Between 1976 and 1990, however, the overall efficacy of the live vaccine was 92% (95% confidence interval 86 to 95%) and there was no evidence of a decline in efficacy (P = 0.13) over the 15-year period. This study suggests that the protection from live measles vaccine persists for up to 27 years after vaccination, and that no change in the current United Kingdom measles immunization policy should be made on the grounds of waning immunity.

    To assess ultrasonographic findings and clinical significance after renal biopsy. 174 cases of post-biopsy sonography were studied retrospectively. We classified post-biopsy hematoma on the basis of their size as small (thickness less than 1 cm, length less than 3cm), medium (thickness less than 1cm, length greater than 3 cm), large (thickness greater than 1 cm, length greater than 3 cm). We also compared bleeding parameters (prothrombin time, partial thromboplastin time) and renal function in both cases which had hematoma or not. Total 33 hematomas were found (19%). Small hematoma was observed in 14 cases, medium hematoma in 16 cases, large hematoma in 3 cases. Severe complications requiring prompt therapy occurred in 1 case(0.6%). In 6 cases hematocrit fell by more than 4%, all of these hematomas were observed on US. Severe complications after sonoguided renal biopsy were rare. There was poor correlation between prebiopsybleeding parameter, renal function and post-biopsy hematomas. And sonography is considered as adequate method for follow up of post-biopsy hematoma

    Energy supplying (i.e. wood and peat fuels) is a new form of entrepreneurship in which one or more entrepreneurs attend to the supply of energy to local buildings. At present there are about ten localities where this is practised. TTS Institute is engaged in a follow-up study of a chipfired heating system with energy entrepreneurs supplying the chipped wood. The study is part of the nationwide Bioenergy research programme. The targets of the study, three in number during the 1993-94 heating season, are rural schools located in southern and eastern Finland. The primary fuel used to heat these premises is chipped wood made from small-diameter timber with light fuel oil as the supplementary fuel. The entrepreneurs supplying the chip fuel are local farmers, and they both delivered the fuel and attended to the actual heating. The time consumed in transporting the chipped wood to the heating plant and to attend to the actual heating was 0,1-1,1 h/MWh with the work associated with heating representing 0,2-0,5 h/MWh. The productivity of fuelwood harvesting in the study sites was 0,4-0,8 m{sup 3}/h and the productivity of chipping was 3,8-7,5 loose m{sup 3}/h. TTS Institute expanded the study in 1994 to also include a few premises larger in their energy requirement than those mentioned in the above

    We designed a follow-up program to find the spectroscopic properties of the Hercules-Aquila Cloud (HAC) and test scenarios for its formation. We measured the radial velocities (RVs) of 45 RR Lyrae in the southern portion of the HAC using the facilities at the MDM observatory, producing the first large sample of velocities in the HAC. We found a double-peaked distribution in RVs, skewed slightly to negative velocities. We compared both the morphology of HAC projected on to the plane of the sky and the distribution of velocities in this structure outlined by RR Lyrae and other tracer populations at different distances to N-body simulations. We found that the behaviour is characteristic of an old, well-mixed accretion event with small apo-galactic radius. We cannot yet rule out other formation mechanisms for the HAC. However, if our interpretation is correct, HAC represents just a small portion of a much larger debris structure spread throughout the inner Galaxy whose distinct kinematic structure should be apparent in RV studies along many lines of sight.

    During a follow-up of 11 years of thyroid carcinoma 136 patients were repeatedly examined. 43% papillary, 43% follicular, 11% anaplastic and 2% medullary carcinomas was found. The incidence of these types of carcinoma differed considerably; the frequency peak of papillary carcinomas was reached in 45-year-old humans, that of the follicular carcinomas in people aged 60, that of the anaplastic carcinomas in 70-year-old humans. 84% of the patients was female. Classification in pTNM-system: 8% in pT1, 27% in pT2, 12% in pT3 and 49% in pT4. Local and distant metastases were found at a low rate equally in pT1, pT2 and pT3; 26% of patients in pT4 had local metastases and 18% had distant ones in addition. There were 6 patients with metastases of a differentiated adenocarcinoma accumulating no 131-iodine and with no thyroglobulin in serum. 29% of patients had after thyroidectomy an unilateral paresis of the nervus recurrens and 4% a bilateral one. 26% of patients had a permanent hypoparathyroidism after thyroidectomy.

    More than 50 planets are discovered with the different ground based telescopes available for microlensing. But the analysis of ground based data fails to provide a complete solution. To fulfill that gap, space based telescopes, like Hubble space telescope and Spitzer are used. My research work focuses on extracting the planet mass, host star mass, their separation and their distance in physical units from HST Follow-up observations. I will present the challenges faced in developing this method.This is the primary method to be used for NASA's top priority project (according to 2010 decadal survey) Wide Field InfraRed Survey Telescope (WFIRST) Exoplanet microlensing space observatory, to be launched in 2025. The unique ability of microlensing is that with WFIRST it can detect sub-earth- mass planets beyond the reach of Kepler at separation 1 AU to infinity. This will provide us the necessary statistics to study the formation and evolution of planetary systems. This will also provide us with necessary initial conditions to model the formation of planets and the habitable zones around M dwarf stars.

    Full Text Available Hereditary multiple exostoses is an autosomal dominant disease with abnormal bone formation especially at the long bones. Osteochondromas, which occur in the course of the disease, can cause growth disturbances in affected children. Due to pressure effects of osteochondromas, compression of vessels, nerves and tendons, restriction of joint motion, and neurologic compromise as well as painful local symptoms can be seen. Here, we aimed to present two siblings who had generalized pain and swelling in different parts of the body. We detected multiple osteochondromas in different parts of their bodies, especially at the long bones. Our patients had painful local symptoms. There was no growth retardation, but the presence of many osteochondromas led us to contemplate that it was serious form of the disease. Their father had lesser number of osteochondromas. In this paper, we aimed to emphasize the necessity of close follow-up for the risk of malignant transformation of osteochondromas. (The Me­di­cal Bul­le­tin of Ha­se­ki 2014; 52: 116-9

    The Dominican Republic conducted a national follow-up measles vaccination campaign 6 weeks after sustaining heavy damage from Hurricane Georges, on November 6-12, targeting 830,517 children aged 9 months to 5 years in 29 provinces and the capital city. This campaign was the first mass vaccination effort in the country, following the beginning of the decentralized delivery of health services. Priority was given to vaccinating against diphtheria, whooping cough, and tetanus, especially in refugee camps. More than 500,000 vaccines were given to different age groups, with almost 100,000 of those immunized under 5 years old. Children aged 9 months to 5 years were targeted for immunization regardless of their vaccination status. At the same time, children aged 2 months through 2 years were immunized against poliomyelitis. Vaccination activities were continued until the entire target population was reached and no important side effects have thus far been reported. The government of Mexico donated 300,000 doses of measles vaccine, while other vaccines for the campaign were acquired through the PAHO Revolving Fund for Vaccine Procurement. The decentralized implementation of this campaign allowed the population to actively participate and the resulting high vaccination coverage rates.

    Purpose: Report our experience in the evaluation and follow-up of thoracic aortic coarctation with MRI and describe its role to estimate trans-stenotic flow. Material and methods: 43 MR examinations were performed in 30 patients (age range 15 days to 73 years) referred to our institution in the last 7 years. Results: MRI visualized the ascending, horizontal and descending portions of the aorta and the supra-aortic vessels in 42/43 patients. MRI clearly identified preoperatively an aortic coarctation in 11/12 cases confirmed by surgery. Postoperatively MRI depicted 4 restenosis and one aneurysm. In 5 patients MRI demonstrated pseudo-coarctation. A significant correlation was established between the maximal trans-stenotic pressure gradient when measured by Doppler US or angiography and the size of the signal void measured on cine-MR images (r=0.72; p<0.01). Conclusion: MRI is a reliable non invasive investigation method for the diagnosis and semi-quantitative evaluation of aortic coarctation particularly when colour Doppler US is not satisfactory.

    Full Text Available Abstract Background Cervical carcinoma remains the second leading cause of cancer death in women worldwide and sexual behavior is regarded as the main contributing factor. We studied cervical cytology screening with surgical biopsy follow-up in women prisoners and compared the findings to those in the general population. Methods We reviewed 1024 conventional cervical smears, 73 cervical biopsies and 2 loop electrosurgical excision procedure (LEEP specimens referred to us from the Correctional Center in Columbus, Ohio during a 12-month period. The results were compared to 40,993 Pap smears from the general population for the same 12-month period. Results High grade squamous intraepithelial lesion (HGSIL was diagnosed in 1.3% of the cervical smears from the inmate population versus 0.6% in the general population (p < 0.01. The unsatisfactory rate was 1.6% compared to 0.3% in the general population (p < 0.01. Among the study population, follow-up tissue diagnosis was obtained in 24.3% of the abnormal cytology results (ASCUS, LGSIL, and HGSIL. Of the HGSIL Pap smears, 61.5% had a subsequent tissue diagnosis. Thirty-nine biopsies (52% of the all inmate biopsies and LEEP showed CIN II/III (cervical intraepithelial neoplasia II/III. Eight of these thirty-nine follow-up biopsies diagnosed as CIN II/III had a previous cervical cytology diagnosis of ASCUS. The average age for HGSIL was 30.5 years (S.D. = 5.7 and for low grade squamous intraepithelial lesion (LGSIL was 27.2 years (S.D. = 6.1. Conclusion A significantly higher prevalence of HGSIL cervical cytology and unsatisfactory smears was encountered in female inmates, with tissue follow-up performed in less than two thirds of the patients with HGSIL. These results are in keeping with data available in the literature suggesting that the inmate population is high-risk and may be subject to less screening and tissue follow-up than the general population. Clinicians should proceed with urgency to improve

    Acute heart failure (AHF) is a major public health issue due to high incidence and poor prognosis. Only a few studies are available on the long-term prognosis and on outcome predictors in the unselected population attending the emergency department (ED) for AHF. We carried out a 1-year follow-up analysis of 1234 consecutive patients from selected Italian EDs from January 2011 to June 2012 for an episode of AHF. Their prognosis and outcome-associated factors were tested by Cox proportional hazard model. Patients' mean age was 84, with 66.0% over 80 years and 56.2% females. Comorbidities were present in over 50% of cases, principally a history of acute coronary syndrome, chronic obstructive pulmonary disease, diabetes, chronic kidney disease, valvular heart disease. Death occurred within 6 h in 24 cases (1.9%). At 30-day follow-up, death was registered in 123 cases (10.0%): 110 cases (89.4%) died of cardiovascular events and 13 (10.6%) of non-cardiovascular causes (cancer, gastrointestinal hemorrhages, sepsis, trauma). At 1-year follow-up, all-cause death was recorded in 50.1% (over 3 out of 4 cases for cardiovascular origin). Six variables (older age, diabetes, systolic arterial pressure capacity (AUC = 0.649; SE 0.015). Recurrence of AHF was registered in 31.0%. The study identifies a cluster of variables associated with 1-year mortality in AHF, but their predictive capacity is low. Old age and the presence of comorbidities, in particular diabetes are likely to play a major role in dictating the prognosis.

    Cardiovascular risk (CV) factors associated with the metabolic syndrome (MetS) may vary in different populations. In some, hypertension may be the major determinant, in others are low high-density lipoprotein cholesterol (HDL-C), high triglycerides, or another component. Subjects included in this analysis were identified in 2006, among those attending the Lipid Clinic of the Niguarda Hospital, and followed up through to 2013. Patient characteristics (including the occurrence of CV events) were obtained from electronic medical records. MetS was diagnosed according to the American Heart Association/National Heart, Lung and Blood Institute (AHA/NHLBI) guidelines. The carotid intima media thickness (cIMT) was also followed in these patients over the years. After 7 years a total of 858 subjects had a complete follow-up; 271 of those had MetS. Patients developing a CV event showed elevated baseline cIMT (e.g. cIMTmax ≥ 2.4 mm in males and ≥ 2.2 mm in females); moreover the cIMT in MetS patients was higher at baseline and the rise over 7 years was larger compared with patients without MetS. By examining each body variable for MetS we found that a waist to height ratio (WHtR) ≥ 0.5 was present in nearly all subjects with a CV event. The follow-up data of a series of Italian patients with and without MetS, clearly indicates that the former have a raised cIMT and their arterial IMT progression is greater and the presence of a larger WHtR is apparently linked to a higher incidence of CV events.

    To determine whether there was a relationship between postpartum psychosocial support from healthcare providers and the rate of normal newborn readmissions (NNRs), and whether there was a cost benefit to justify an intervention. Data were abstracted for all normal newborn births from 1999 to 2006 (N = 14,786) at a community hospital in southern California at three different time periods: (1) at baseline prior to any intervention (1999-2000), (2) the 4 years during the comprehensive psychosocial support intervention (2001-2004), and (3) the 2 years during a limited psychosocial support intervention (2004-2006). A cost-benefit analysis was performed to analyze whether the financial benefits from the intervention matched or exceeded the costs for NNRs. There was a significantly lower readmission rate of 1.0% (p = < .001) during the comprehensive intervention time period compared to baseline (2.3%) or to the limited intervention time period (2.3%). Although there was no significant difference in the average cost per newborn readmitted across the three study time periods, during the comprehensive intervention time period the average costs of a NNR were significantly lower ($4,180, p = .041) for the intervention group compared to those who received no intervention ($5,338). There was a cost benefit of 513,540 dollars due to fewer readmissions during the comprehensive time period, but it did not exceed the cost of the intervention. Providing comprehensive follow-up for new mothers in the postpartum period can reduce NNRs, thus lowering the average newborn readmission costs for those who receive psychosocial support. Followup for new mothers should be an accepted norm rather than the exception in postpartum care, but NNRs should not be considered the sole outcome in such programs.

    We describe the evolution of parenchymal cerebral cysticerci on MRI, to assess signs of early cyst degeneration. We studied 15 lesions in four treated and one untreated patient. MRI was performed before therapy and repeated in the 1st month after each course of anticysticercus drugs, every 4 months during the 1st year and then annually; the follow-up period was 8-48 months. Lesions were classified according to changes in four features: cyst content and capsule signal, gadolinium enhancement and oedema signal. We were able to recognise each of the pathological phases; five MRI stages were identified. Stage 1 showed oedema and/or nodular gadolinium enhancement in the tissue invasion phase; stage 2 was cerebrospinal fluid-like signal within a cyst in the vesicular phase; stage 3 showed a thick capsule with an impure liquid content signal and surrounding oedema, in the cystic phase; stage 4 showed the disappearance of the cyst fluid content signal in the degenerative phase; stage 5 showed a calcified lesion in the residual phase. Stage 1 lesions disappeared after therapy; the other progressed from one stage to another. Stage 4 indicated the end of viability of the parasite and determined the point after which treatment was useless. On T2-weighted images changes in the cyst content differed according to the history of the lesion; nodular low intensity followed the natural degeneration of the parasite and a mixed fluid signal with punctate low signal seemed to represent the specific result of therapy. MRI staging can help in the evaluation of indications for treatment and facilitate clinical therapeutic trials. (orig.). With 4 figs., 1 tab

    Full Text Available Background: Paroxysmal nocturnal hemoglobinuria (PNH is characterized by intravascular hemolysis, marrow failure, nocturnal hemoglobinuria and thrombophila. This acquired disease caused by a deficiency of glycosylphosphatidylinositol (GPI anchored proteins on the hematopoietic cells is uncommon in the Indian population. Materials and Methods: Data of patients diagnosed with PNH in the past 1 year were collected. Clinical data (age, gender, various presenting symptoms, treatment information and follow-up data were collected from medical records. Results of relevant diagnostic tests were documented i.e., urine analysis, Ham′s test, sucrose lysis test and sephacryl gel card test (GCT for CD55 and CD59. Results: A total of 5 patients were diagnosed with PNH in the past 1 year. Presenting symptoms were hemolytic anemia (n=4 and bone marrow failure (n=1. A GCT detected CD59 deficiency in all erythrocytes in 4 patients and CD55 deficiency in 2 patients. A weak positive PNH test for CD59 was seen in 1 patient and a weak positive PNH test for CD55 was seen in 3 patients. All patients were negative by sucrose lysis test. Ham′s test was positive in two cases. Patients were treated with prednisolone and/or androgen and 1 patient with aplastic anemia was also given antithymocyte globulin. A total of 4 patients responded with a partial recovery of hematopoiesis and 1 patient showed no recovery. None of the patients received a bone marrow transplant. Conclusion: The study highlights the diagnostic methods and treatment protocols undertaken to evaluate the PNH clone in a developing country where advanced methods like flowcytometry immunophenotyping (FCMI and bone marrow transplants are not routinely available.

    Academic conferences offer numerous submission tracks to support the inclusion of a variety of researchers and topics. Work in progress papers are one such submission type where authors present preliminary results in a poster session. They have recently gained popularity in the area of Human Computer Interaction (HCI) as a relatively easier pathway to attending the conference due to their higher acceptance rate as compared to the main tracks. However, it is not clear if these work in progress papers are further extended or transitioned into more complete and thorough full papers or are simply one-off pieces of research. In order to answer this we explore self-citation patterns of four work in progress editions in two popular HCI conferences (CHI2010, CHI2011, HRI2010 and HRI2011). Our results show that almost 50% of the work in progress papers do not have any self-citations and approximately only half of the self-citations can be considered as true extensions of the original work in progress paper. Specific conferences dominate as the preferred venue where extensions of these work in progress papers are published. Furthermore, the rate of self-citations peaks in the immediate year after publication and gradually tails off. By tracing author publication records, we also delve into possible reasons of work in progress papers not being cited in follow up publications. In conclusion, we speculate on the main trends observed and what they may mean looking ahead for the work in progress track of premier HCI conferences.

    Renal artery fibromuscular dysplasia (RA-FMD) has a higher prevalence among women and a presumed hormonal etiology. Although preeclampsia has a clinical presentation similar to symptomatic RA-FMD and occurs exclusively in women, associations between these 2 diseases have not been characterized. To explore epidemiologic associations between RA-FMD and preeclampsia, we administered a validated screening instrument for preeclampsia to a cohort of women with a history of pregnancy who had previously been treated with procedural intervention for symptomatic RA stenosis. Women with a history of pregnancy who had previously undergone procedural intervention (including angioplasty and/or bypass) for symptomatic RA stenosis were identified from a prospectively maintained operative registry and screened for remote history of preeclampsia using a validated survey instrument. Univariable associations between RA-FMD and preeclampsia among participants with a history of pregnancy were evaluated using t-tests for continuous factors and chi-squared tests for dichotomous factors. Multivariable associations were evaluated using logistic regression models. A total of 144 women were identified who met the study inclusion criteria, including 94 with atherosclerotic RA stenosis and 50 with RA-FMD. Sixty-nine patients were contacted, 59 consented to participate, and 52 had a history of pregnancy (and therefore were at risk for preeclampsia). Participants completed the survey instrument at a mean of 7.1 ± 3.1 vs. 6.9 ± 3.6 years after RA procedural intervention, respectively. Survey responses indicated a history of preeclampsia in 19/52 (36.5%) of participants overall, including 14/27 (51.9%) with RA-FMD versus 5/20 (20.0%) with RA atherosclerosis (P = 0.02). Preeclampsia remained associated with FMD in a multivariable model adjusting for smoking status, age at time of surgery, and estimated glomerular filtration rate (odds ratio [OR] 9.51, 95% confidence interval [CI] 1.49-60.6, P = 0

    Indication Presentation and evaluation of diagnostic procedures for the follow-up in patients with suspected local recurrence of rectal cancer. Follow-up usually is performed using endoscopy and endosonography. Imaging techniques applied are also contrast enema as well as helical CT,MR imaging (MRI), and positron emission tomography (PET). The results demonstrate the difficulty of all available modalities to differentiate between early tumor recurrences from posttherapeutic alterations.Especially the differentiation of scar tissue and local tumor recurrence, the detection of lymph node as well as pulmonary or hepatic metastasis requires a large diagnostic effort with employment of various imaging modalities. Values determined for sensitivity and specificity for CT are 84% and 91% with a positive predictive value (PPV) of 78%.For MRI and PET the sensitivity are 94% and 98%,and the specificity 92% and 90% with a PPV of 93% for the PET. The results demonstrate the increasing importance of CT and MRI in the follow-up of patients with rectal cancer and enable an accurate and early diagnosis through employment of new examination strategies and sequence protocols.PET remains an add-on examination in uncertain local lesions.

    Objectives: To determine in paediatric patients with atrial septal defects whether differences in P wave dispersion occurred with transcatheter closures using the Amplatzer septal occluder. Method: A total of 31 children who had undergone transcathater closures were evaluated. P maximum, P minimum, and P dispersion were measured with 12-lead surface electrocardiography, before the procedure and one week, one month, three months, six months and one year following the procedure. SPSS 10 was used for statistical analysis. Results: There were 23 (74.2%) females and 8 (25.8%) males with an overall mean age of 7.5+-4.1 years and mean weight of 26.2+-16.9kg. The P maximum and P minimum measurements differed between patients during the follow-up period. Both measurements decreased with time. However, P dispersion was not significantly different throughout the follow-up period (before the procedure P maximum 95.4+-15.6 ms, P minimum 64.5+-15.4 ms, and P dispersion 30.8+-11.4ms; one year later, P maximum 76.1+-14.6 ms, P minimum 47.1+-12.1 ms, and P dispersion 29.1+-9.1ms). Conclusion: Over time, there are no P dispersion differences in transcatheter closures using the Amplatzer septal occluder. (author)

    In routine thoracic X-ray follow-ups after cardiosurgical procedures, 93.2% of our patients (n=88) showed radiologically perceivable pathological changes, reduced ventilation being the most common phenomenon. 77.1% of the patients showed signs of reduced ventilation, mostly the left side. Limited motility of the diaphragm on the left side was visible in 69% of the cases studied. The defective motility of the left diaphragm is attributable to direct damage to the left nervus phrenicus caused by extracardial heart cooling during surgery.

    Purpose. This study was designed to describe the technique of arterial occlusion using a temporary occlusion balloon system as an alternative to coil occlusion during Yttrium-90 radioembolization of hepatic tumors. Methods. Review of charts, angiography, and follow-up imaging studies of consecutive patients undergoing oncological embolization procedures in which a HyperForm system (ev3 Neurovascular, Irvine, CA) was used. Intraprocedural target vessel occlusion and patency of the target vessel on follow-up were recorded. Clinical data and Bremsstrahlung scans were reviewed for evidence of nontarget embolization. Results. Four radioembolization procedures were performed in three patients (all female, age 48-54 (mean 52) years). Five arteries were temporarily occluded (three gastroduodenal arteries, one right gastric artery, and one cystic artery). All radioembolization procedures were successfully completed. Follow-up imaging (either digital subtraction angiography (DSA) or computed tomography angiography (CTA)) was available for all patients between 28-454 (mean 183) days following the procedure, demonstrating all five vessels to be patent. No clinical or imaging evidence for nontarget embolization was found. Conclusions. Temporary balloon occlusion of small and medium-sized arteries during radioembolization allows safe therapy with preserved postprocedural vessel patency on early and midterm follow-up.

    to an improvement in quality of life, decrease in the number of decompensations, fewer hospital admissions, and better acceptance of the disease. An intervention in a population of diabetic and hypertensive patients, through the establishment of groups to promote educative measures, regular follow-up, drug supply, periodic control and treatment of medical intercurrences was proposed at a Basic Health Unit. Monthly meetings took place during the first three months, followed by periodic medical evaluations, disease control and drug supply for additional 27 months. A series of 191 patients was included for a follow-up. Comparing the initial results and those seen post-intervention, we observed a relative decrease of 42% and an absolute one of 26% in the number of patients with moderate and severe hypertension. Regarding the diabetic patients, there was an absolute decrease of 22% in those with glycemia levels above 200mg/dl and an increase of 33% for those with levels below 125mg/dl. For patients who depend on the public health system and drug supply by the government, mostly elderly patients with low schooling, the intervention proved to be effective, although the control of the diseases and all adherence determinants was not achieved. We suggest the implementation of this intervention.

    The aim of this study was to analyze complications and outcomes of end-to-end urethral anastomosis performed for posttraumatic bulbar strictures or posterior urethral injuries in pediatric patients. The records of 15 boys, age 18 years and below, admitted to our tertiary trauma center with urethral injuries from 1989 to 2014 were reviewed retrospectively. Out of these 15 boys, 7 were excluded (2 for iatrogenic trauma, 2 for minor straddle injuries who were not operated on, 2 for incomplete records, and 1 lost to follow-up) and 8 analyzed patients were operated for bulbar or posterior urethral injury. The mean follow-up after the operation was 4.5 years (range 0.5-10). To obtain up-to-date follow-up information, all the analyzed patients were contacted by a letter and telephone in January 2015 and asked about lower urinary tract or erectile dysfunction (ED) using the International Index of Erectile Function-5 questionnaire. Mean age at the time of injury was 12.3 years (range 5-17). Four patients with pelvic fracture had complete posterior urethra disruption, three patients after straddle injury developed obliterating stricture of the bulbar urethra and one patient had torn his bulbar urethra apart by a sharp hook. Except for the immediate exploration of the open perineal wound, all patients were operated via perineal approach 1 to 6 months after initial suprapubic catheter insertion. Five patients needed a cystotomy to identify the proximal urethral stump by a probe, and two patients had partial pubectomy to gain urethral length. Postoperative complications included stricture in anastomosis in six patients (all reoperated, four more than once including attempts of endoscopic internal urethrotomy). Six days after surgery, one patient developed massive external bleeding around a permanent urinary catheter due to a posttraumatic ruptured arterial aneurysm that was later stopped by urgent angiography and coil insertion. After discharge, three patients had transient

    Full text: As part of the International Action Plan for Protection of Patients and supporting by the IAEA, a survey on patient doses in fluoroscopy guided procedures in cardiology in Latin America has been conducted since 2006. One of the objectives of the survey was to set criteria for the identification and evaluation of high skin doses in a certain number of patients to recommend a clinical follow up for potential radiation injuries (more than 3 Gy at the skin). The used methodology for the survey was initiated with two dedicated workshops held in Santiago de Chile (2005) and San Jose de Costa Rica (2007) involving relevant cardiologists from 15 different Latin American Countries. Some sessions were also attended by experts from the Regulatory and Health Authorities. Standardized forms to collect demographic and patient dosimetric data were agreed. Considering that most of the involved centres had still not dosimeters installed in the cardiology x-ray systems, it was agreed to collect data on fluoroscopy time and total number of cine frames per procedure. Relevant factors influencing radio sensitivity of the skin were also collected. Data from 10 countries representing a sample of 709 patients were received during the first year. Procedures included were diagnostic (DG) (coronary angiography and electrophysiology studies), therapeutic (TH) (percutaneous transluminal coronary angioplasties, cardiac ablations and valvuloplasties) or including both DG and TH. A total of 26 patients (3.7%) were selected for potential high skin doses. Initial considered criteria for selection were more than 30 minutes of fluoroscopy, more than 3,000 cine frames per procedure or patients with more than 100 kg of weight. Maximum reported values were 72 minutes and 8,100 frames. In addition, 5 of these patients were diabetic, 6 have previous fluoroscopy procedures and 5 were over 95 kg. The percentage of selected cases for clinical follow up derived from potential skin injuries seem

    This study analyzed clinical long-term outcomes after endoscopic therapy, including the incidence and treatment of relapse. This study included 19 consecutive patients (12 male, 7 female, median age 54 years) with obstructive chronic pancreatitis who were admitted to the 2(nd) Medical Department of the Technical University of Munich. All patients presented severe chronic pancreatitis (stage III°) according to the Cambridge classification. The majority of the patients suffered intermittent pain attacks. 6 of 19 patients had strictures of the pancreatic duct; 13 of 19 patients had strictures and stones. The first endoscopic retrograde pancreatography (ERP) included an endoscopic sphincterotomy, dilatation of the pancreatic duct, and stent placement. The first control ERP was performed 4 wk after the initial intervention, and the subsequent control ERP was performed after 3 mo to re-evaluate the clinical and morphological conditions. Clinical follow-up was performed annually to document the course of pain and the management of relapse. The course of pain was assessed by a pain scale from 0 to 10. The date and choice of the therapeutic procedure were documented in case of relapse. Initial endoscopic intervention was successfully completed in 17 of 19 patients. All 17 patients reported partial or complete pain relief after endoscopic intervention. Endoscopic therapy failed in 2 patients. Both patients were excluded from further analysis. One failed patient underwent surgery, and the other patient was treated conservatively with pain medication. Seventeen of 19 patients were followed after the successful completion of endoscopic stent therapy. Three of 17 patients were lost to follow-up. One patient was not available for interviews after the 1(st) year of follow-up. Two patients died during the 3(rd) year of follow-up. In both patients chronic pancreatitis was excluded as the cause of death. One patient died of myocardial infarction, and one patient succumbed to

    To evaluate and compare the radiologic and clinical follow-up of complications between a group in whom stone removal after percutaneous biliary extraction had been complete, and a group in whom this had been incomplete. Twenty-two patients in whom stone removal had been incomplete, and 20 from whom stones had been completely removed were evaluated with particular attention to complications such as cholangitis, liver abscess, biliary sepsis, and pain. Cholangitis was diagnosed on the basis of typical clinical symptoms such as pain, high fever, jaundice and leukocytosis. Pain without other cholangitic symptoms was excluded. Liver abscess was diagnosed by percutaneous aspiration of pus, and biliary sepsis by bacterial growth on blood culture, or laboratory findings such as increased fibrinogen products, decreased fibrinogen, and increased prothrombin time with cholangitic symptoms. 'Complete removal' means no residual stones on follow-up sonogram and cholangiogram performed within three to seven days after pecutaneous biliary extraction. Mean follow-up period was 26.5 months in the incomplete removal group and 34.2 months in the complete removal group. In twelve of 22 patients (54.5%) in the incomplete removal group, complications occurred, as follows:cholangitis, ten cases (45.5%);liver absces, one (4.5%);biliary sepsis, one (4.5%);and pain, seven(31.8%). In contrast, only two of twenty patients (10%) in the complete removal group suffered complications, all of which involved the recurrence of stones in the common duct, and cholangitis. Complete removal of intrahepatic stones significantly helps to reduce the incidence of possible complications. Even in the case of an impacted stone, aggressive interventional procedures, aimed at complete removal, should be considered. If nonsurgical procedures fail, early partial hepatectomy should be considered, particulary for the stones localized in the left intrahepatic duct

    Recent reports have revealed a worsening of aneurysm occlusion between WEB treatment baseline and angiographic follow-up due to "compression" of the device. We utilized computational fluid dynamics (CFD) in order to determine whether the underlying mechanism of this worsening is flow related. We included data from all consecutive patients treated in our institution with a WEB for unruptured aneurysms located either at the middle cerebral artery or basilar tip. The CFD study was performed using pre-operative 3D rotational angiography. From digital subtraction follow-up angiographies patients were dichotomized into two groups: one with WEB "compression" and one without. We performed statistical analyses to determine a potential correlation between WEB compression and CFD inflow ratio. Between July 2012 and June 2015, a total of 22 unruptured middle cerebral artery or basilar tip aneurysms were treated with a WEB device in our department. Three patients were excluded from the analysis and the mean follow-up period was 17months. Eleven WEBs presented "compression" during follow-up. Interestingly, device "compression" was statistically correlated to the CFD inflow ratio (P=0.018), although not to aneurysm volume, aspect ratio or neck size. The mechanisms underlying the worsening of aneurysm occlusion in WEB-treated patients due to device compression are most likely complex as well as multifactorial. However, it is apparent from our pilot study that a high arterial inflow is, at least, partially involved. Further theoretical and animal research studies are needed to increase our understanding of this phenomenon. Copyright © 2017 Elsevier Masson SAS. All rights reserved.

    Prune belly syndrome is a rare, congenital condition that consists of a major deficiency or hypoplasia of the abdominal wall musculature, bilateral cryptorchidism, and genitourinary tract malformations. Reconstruction of the abdominal wall in these patients has presented a challenge to plastic surgeons throughout the years. The authors previously described a technique for total abdominal wall reconstruction that permitted simultaneous urinary tract reconstruction and bilateral orchiopexy. This innovative procedure used medial advancement of the fascia in a "double-breasted" fashion with preservation of the umbilicus. The authors reviewed their experience with this particular technique in one of the largest series of patients in the literature and the series with the longest follow-up. Twenty patients underwent total abdominal wall reconstruction with simultaneous urinary tract reconstruction and orchiopexy with a mean follow-up of 20.4 years. There were no major complications noted during this period, and all patients were extremely satisfied with their postoperative result. Total abdominal wall reconstruction using the double-breasted technique in patients with prune belly syndrome is a safe and durable procedure that achieves excellent cosmetic results.

    The staging procedures for small cell lung cancer do not differ appreciably from those for other forms of lung cancer. For practical purposes, the TNM stages are usually collapsed into a simple binary classification: limited disease and extensive disease. This study was performed to answer the question of whether fluorine-18 labelled 2-deoxy-2-D-glucose positron emission tomography (FDG-PET) imaging permits appropriate work-up (including both primary and follow-up staging) of patients presenting with small cell lung cancer, as compared with currently recommended staging procedures. Thirty-six FDG-PET examinations were performed in 30 patients with histologically proven small cell lung cancer. Twenty-four patients were examined for primary staging while four were imaged for therapy follow-up only. Two patients underwent both primary staging and up to four examinations for therapy follow-up. Static PET imaging was performed according to a standard protocol. Image reconstruction was based on an ordered subset expectation maximization algorithm including post-injection segmented attenuation correction. Results of FDG-PET were compared with those of the sum of other staging procedures. Identical results from FDG-PET and the sum of the other staging procedures were obtained in 23 of 36 examinations (6 x limited disease, 12 x extensive disease, 5 x no evidence of disease). In contrast to the results of conventional staging, FDG-PET indicated extensive disease resulting in an up-staging in seven patients. In one patient in whom there was no evidence for tumour on conventional investigations following treatment, FDG-PET was suggestive of residual viability of the primary tumour. Furthermore, discordant results were observed in five patients with respect to lung, bone, liver and adrenal gland findings, although in these cases the results did not affect staging as limited or extensive disease. Moreover, FDG-PET appeared to be more sensitive for the detection of metastatic

    Full Text Available ObjectivesTo assess the optimal length of follow-up for patients undergoing both open and minimally invasive pyeloplasties to ensure prompt detection of a recurrent obstruction. There are no standard guidelines on ideal follow-up and imaging post-pediatric pyeloplasty currently.MethodsA retrospective chart review identified 264 patients (<18 years old who underwent pyeloplasty for ureteropelvic junction obstruction between April 2002 and December 2014. Ultrasound was obtained every 3–4 months for the first year following pyeloplasty and thereafter at discretion of treating physician. Patient characteristics including symptoms and imaging were reviewed.ResultsOf the 264 patients, 72% were male with mean age of 51 months and follow-up of 26.8 months. Approximately 73% followed up to 3 years. Fourteen patients (5.3% had a recurrent obstruction. Among the failures, 85% were diagnosed and underwent successful redo pyeloplasty within 3 years. Six infants had a recurrence (43% of all unsuccessful surgeries and were diagnosed within 3 years of the initial surgery. Patients undergoing a minimally invasive procedure were less likely to be followed for more than 3 years compared to an open procedure (p < 0.001. Patients with severe hydronephrosis preoperatively were followed longer (p = 0.031. Age at surgery and type of surgical approach (p < 0.01 were significant predictors of length of follow-up in a negative binomial regression.ConclusionBased on the results, a minimum of 3 years of follow-up is necessary to detect the majority of recurrent obstructions. Those patients who have higher than average lengths of follow-up tend to be younger and/or underwent an open surgical approach.

    BACKGROUND: Allogeneic red blood cell transfusion is frequently used in total hip replacement surgery (THR). However, data on the prognosis of transfused patients are sparse. In this study we compared the risk of complications following THR in transfused and non-transfused patients. METHODS......: A population-based follow-up study was performed using data from medical databases in Denmark. We identified 28,087 primary THR procedures performed from 1999 to 2007, from which we computed a propensity score for red blood cell transfusion based on detailed data on patient-, procedure-, and hospital......-related characteristics. We were able to match 2,254 transfused with 2,254 non-transfused THR patients using the propensity score. RESULTS: Of the 28,087 THR patients, 9,063 (32.3%) received at least one red blood cell transfusion within 8 days of surgery. Transfused patients had higher 90-day mortality compared...

    The incidence of chronic pancreatitis is increasing in industrialized countries due to the steady increase of alcohol abuse. The pathogenesis of this disease is still incompletely understood. A cure is not possible. The knowledge of the patients history and a thorough clinical investigation together with the availability of a wide array of laboratory tests and imaging procedures enable the physician to characterize the stage of the disease. Exact knowledge of the present pancreatic morphology, potential complications of the disease, and knowledge about the present exocrine and endocrine function capacity are prerequisites for adequate therapeutic decision making. The therapeutic possibilities include termination of alcohol abuse, various options of treatment of pain according to the various pathogenetic possibilities leading to pain, pancreatic digestive enzyme supplementation, treatment of diabetes, and either endoscopic or surgical treatments of complications of the disease.

    This study reports on 6 years experience with IPS Empress laminate veneers. A total of 83 anterior veneers were positioned in 21 patients from January 1991 to December 1996 in the author's private practice. Final evaluation was carried out in May and June 1997. Color match, marginal discoloration, recurrent caries, contour, and marginal integrity were evaluated using the modified U.S. Public Health Service criteria at baseline and subsequent recall appointments. On the basis of the criteria used, a large percentage of veneers were rated Alfa. Only one failure was recorded, resulting in a success rate of 98.8%. A thorough description of clinical procedures and laboratory techniques through which anterior teeth can be successfully treated with ceramic veneers is supplied. A clinical case is presented to demonstrate the satisfactory esthetic results obtained using this very conservative restorative technique.

    multiple occlusions of the digital arteries (57.4%). All patients were advised to change their occupational exposure. They were given vasodilators, including calcium channel blocker (n = 37) and buflomedil (n = 12); 36 patients (76.6%) also received oral platelet aggregation inhibitors. Twenty-one patients with digital ischemia/necrosis were further given hemodilution therapy to reduce the hematocrit level to 35%. In 3 patients with HHS-related digital necrosis who exhibited partial improvement with vasodilators, prostacyclin analog therapy (a 5-day regimen of intravenous prostacyclin analog) was instituted, resulting in complete healing of digital ulcer in these 3 patients. Other conservative treatment options included controlling risk factors (smoking cessation, low-lipid diet, therapy for arterial hypertension) and careful local wound care of fingers in the 20 patients with digital necrosis. Only 2 patients, exhibiting digital necrosis and multiple digital artery occlusions, with nonthrombotic ulnar artery aneurysm underwent reconstructive surgery, that is, resection of the aneurysm with end-to-end anastomosis of the ulnar artery. The median length of follow-up in patients with HHS was 15.9 months. Thirteen patients (27.7%) exhibited clinical recurrences of HHS; the median time of HHS recurrence onset was 11 months. Outcome of HHS relapse was favorable with conservative measures in all cases. Awareness of HHS is required to increase suspicion of the disorder so that further exposure to risk factors like repetitive hypothenar trauma can be avoided for these patients; this is of great importance for their overall prognosis. We found favorable outcomes in most patients after conservative measures were initiated; therefore we suggest that surgery may be undertaken in the subgroup of patients who exhibit partial improvement while receiving conservative therapy. Finally, because we observed recurrence of HHS in 27.7% of patients, we note that HHS patients require close follow-up

    Carotid artery stenting has emerged as an acceptable treatment alternative in patients with carotid artery stenosis. Although early clinical results of carotid artery stenting have shown promise, long, term clinical results remain less certain. We report the frequency, management, and clinical results of in-stent restenosis after carotid artery stenting using a self-expandable stent. Between August 1998 and September 2004, 80 carotid artery stenting procedures in 78 patients were performed. We evaluated 76 of the 80 procedures in 75 of the 78 patients treated during this period who had a minimum 6-month clinical and imaging (ultrasound and/or magnetic resonance angiography) follow-up. Recurrent stenosis (≥50%) after carotid artery stenting occurred in 3 (3.9%) patients. The recurrent stenosis occurred within one year after the procedure in all cases. The low rate of in-stent restenosis using self-expandable stent suggested that carotid artery stenting may be an effective alternative treatment for carotid artery stenosis, but more data of long-term follow-up are required.

    Full Text Available Background: Regular follow up and amblyopia treatment are essential for good outcomes after pediatric cataract surgery. Aim: To study the regularity of follow-up after cataract surgery in children and to gauge the causes of poor compliance to follow up. Subjects: 262 children (393 cataracts who underwent cataract surgery in 2004-8. Materials and Methods: The children were identified and examined in their homes and a "barriers to follow-up" questionnaire completed. Demographic data collected, visual acuity estimated, and ocular examination performed. Statistical Analysis: SPSS version 19. Results: Of the 262 children, only 53 (20.6% had been regularly following up with any hospital, 209 (79.4% had not. A total of 150 (57.3% were boys and the average age was 13.23 years (Std Dev 5 yrs. Poor follow up was associated with the older age group ( P 1 line with regular follow-up. Conclusion: Regular follow-up is important and improves vision; eye care practitioners need to take special efforts to ensure better follow-up.

    Arterial hypertension is responsible for a significant burden of cardiovascular morbidity and mortality, worldwide. Although several rational and integrated pharmacological strategies are available, the control of high blood pressure still remains largely unsatisfactory. Failure to achieve effective blood pressure control in treated hypertensive patients may have a substantial impact on individual global cardiovascular risk, since it significantly increases the risk of developing hypertension-related macrovascular and microvascular complications. Arterial hypertension is arbitrarily defined as 'resistant' or 'refractory' when the recommended blood pressure goals (clinic blood pressure below 140/90 mmHg or below 130/80 mmHg in patients with type 2 diabetes mellitus or nephropathy) are not achieved in the presence of a therapeutic strategy that includes lifestyle changes and at least three classes of antihypertensive drugs, including a diuretic, at adequate doses. Recently, an innovative non-pharmacological option has become available for treating resistant hypertension. Sympathetic denervation of renal arteries is a minimally invasive procedure that is performed via percutaneous access from the femoral artery. It consists of radiofrequency ablation of the afferent and efferent nerves of the renal sympathetic nervous system, with consequent isolation of renal parenchymal and juxtaglomerular structures from abnormal stimulation of the efferent adrenergic system. The present position paper of the Italian Society of Hypertension (SIIA) offers a diagnostic and therapeutic approach for the proper identification and effective clinical management of patients with resistant hypertension, who are candidates for renal artery denervation. These indications may have important implications not only from a clinical point of view, but also from an economic point of view, since a proper identification of patients with true resistant hypertension and an accurate selection of patients

  16. Aortopulmonary collateral flow is related to pulmonary artery size and affects ventricular dimensions in patients after the fontan procedure.

    Directory of Open Access Journals (Sweden)

    Full Text Available BACKGROUND: Aortopulmonary collaterals (APCs are frequently found in patients with a single-ventricle (SV circulation. However, knowledge about the clinical significance of the systemic-to-pulmonary shunt flow in patients after the modified Fontan procedure and its potential causes is limited. Accordingly, the aim of our study was to detect and quantify APC flow using cardiovascular magnetic resonance (CMR and assess its impact on SV volume and function as well as to evaluate the role of the size of the pulmonary arteries in regard to the development of APCs. METHODS: 60 patients (mean age 13.3 ± 6.8 years after the Fontan procedure without patent tunnel fenestration underwent CMR as part of their routine clinical assessment that included ventricular functional analysis and flow measurements in the inferior vena cava (IVC, superior vena cava (SVC and ascending aorta (Ao. APC flow was quantified using the systemic flow estimator: (Ao - (IVC + SVC. Pulmonary artery index (Nakata index was calculated as RPA + LPA area/body surface area using contrast enhanced MR angiography. The patient cohort was divided into two groups according to the median APC flow: group 1 0.495 l/min/m(2. RESULTS: Group 1 patients had significant smaller SV enddiastolic (71 ± 16 vs 87 ± 25 ml/m(2; p=0.004 and endsystolic volumes (29 ± 11 vs 40 ± 21 ml/m(2; p=0.02 whereas ejection fraction (59 ± 9 vs 56 ± 13%; p=0.38 differed not significantly. Interestingly, pulmonary artery size showed a significant inverse correlation with APC flow (r=-0.50, p=0.002. CONCLUSIONS: Volume load due to APC flow in Fontan patients affected SV dimensions, but did not result in an impairment of SV function. APC flow was related to small pulmonary artery size, suggesting that small pulmonary arteries represent a potential stimulus for the development of APCs.

    Purpose: To provide guidance regarding follow-up procedures after initial treatment of early stage testicular seminoma (clinical stages (CS) I-II A/B) based on current published evidence complemented by expert opinion. Methods and Material: An interdisciplinary, multinational working group consisting of urologists, medical oncologists, and radiation oncologists analyzed the published evidence regarding follow-up procedures in various stages of seminomatous and nonseminomatous testicular cancers. Focusing on radiooncological aspects, the recommendations contained herein are restricted to early stage seminoma (with radiotherapy being a standard treatment option). In particular, extent, frequency, and duration of imaging at follow-up were analyzed concerning relapse patterns, risk factors, and mode of relapse detection. Results: Active surveillance, adjuvant carboplatin or radiotherapy are equally accepted options for CS I seminoma but they result in different relapse rates and patterns. Usually relapses occur within the first 2(-6) years. Routinely performed follow-up using computerized tomography (CT) after adjuvant treatment yield only low detection rates of recurrences. Therefore, there is no evidence to maintain routine examinations every 3-4 months. After treatment of stage IIA/B, detection rates of relapses or progression identified solely by routinely performed CT during follow-up are low. Conclusion: Considering lifelong cure rates of up to 99% for patients treated for seminoma CS I-IIA/B, the negative impact of unnecessary ionizing radiation exposure has to be considered. The presented recommendations for various follow-up scenarios for early stage seminoma strongly promote the restrictive use of imaging procedures that utilize ionizing radiation (especially CT), due to its potential to induce secondary malignancies.

    Objective: To evaluate the impact on cardiac magnetic resonance imaging (CMRI) with adenosine stress and delayed enhancement for indication and follow up after interventional recanalisation of chronic total coronary occlusions (CTOs). Material and methods: Twenty consecutive patients (15 males; 5 females; mean age 65 years) with CTO verified by cardiac catheterisation referred to CMRI. Sixteen of them got CMRI before and after coronary recanalisation. Wall motion abnormalities (WMAs), first pass perfusion with adenosine and viability were assessed using a 1.5 T MR scanner (Sonata; Siemens). CMRI results were compared with clinical classifications, the results of cardiac catheterisation and follow up angiography. Results: Sixteen patients had a successful recanalisation, 15 of the occluded coronary artery and one of collateral donor artery stenosis. After recanalisation all stress-induced progressive or new wall motion abnormalities (WMAs) of the corresponding segments and in the collateral donor territory (5 patients) and all adenosine induced perfusion defects (PD) or delay (12 patients) were regredient. 13/16 patients showed no transmural and one patient transmural delayed enhancement (DE) indicating myocardial scar. In 10/16 patients CSS grading of angina improved after recanalisation. Conclusion: After successful recanalisation of CTOs, patients with preinterventional stress-induced PDs and WMAs in viable myocardium did not display any signs of stress-induced ischemia postinterventionally. A comprehensive CMRI approach, including assessment of rest and stress WMAs, first pass perfusion and myocardial viability represents an important tool for the pre-interventional decision to recanalise CTOs and follow up.

    Purpose: To assess the change in diagnostic confidence between first and follow-up dynamic MR examination of the breast (MRM). Methods: The reports of a total of 175 MRM in 77 patients (mean age 50 years; 36-76) with 98 follow-up MRM were analyzed. All examinations were performed as a dynamic study (Gd-DTPA, 0.16 mmol/kg; 6-7 repetitive studies). The change in diagnostic confidence was retrospectively classified as follows: Controlled lesion vanished during follow-up (category I); diagnostic confidence increases during follow-up (II), more likely benign (IIa), more suspicious (IIb); no difference in diagnostic confidence (III). Long-term follow-up over an average of four years was obtained for 57 patients with category IIa/III findings. Results: In 98 follow-up examinations, only two lesions vanished (2%). In 77/98 cases a category IIa lesion was diagnosed, in 11 cases a category IIb lesion. In 8 cases (8%) there was no change in diagnostic confidence during follow-up. Lesions in category IIb underwent biopsy in 10/11 cases, in one case long-term follow-up proved a completely regredient inflammatory change. In 8/11 suspicious findings (IIb) a malignant tumor was detected. The mean time interval between first and follow-up MRM was 8 months for I-IIb lesions, and 4 months for category III lesions. In the longterm follow-up two patients with a category II a lesion developed a carcinoma in a different breast area after four and five years. Conclusion: MRM follow up increases the diagnostic confidence if the time interval is adequate (>4 months). A persistently or increasingly suspicious finding warrants biopsy. (orig.) [de

    US guided HIFU/FUS ablation for the therapy of prostate cancer is a clinical established method, while MR guided HIFU/FUS applications for prostate recently started clinical evaluation. Even if MRI examination is an excellent diagnostic tool for prostate cancer, it is a time consuming procedure and not practicable within an MRgFUS therapy session. The aim of our ongoing work is to develop software to support therapy planning and post-therapy follow-up for MRgFUS on localized prostate cancer, based on multi-parametric MR protocols. The clinical workflow of diagnosis, therapy and follow-up of MR guided FUS on prostate cancer was deeply analyzed. Based on this, the image processing workflow was designed and all necessary components, e.g. GUI, viewer, registration tools etc. were defined and implemented. The software bases on MeVisLab with several implemented C++ modules for the image processing tasks. The developed software, called LTC (Local Therapy Control) will register and visualize automatically all images (T1w, T2w, DWI etc.) and ADC or perfusion maps gained from the diagnostic MRI session. This maximum of diagnostic information helps to segment all necessary ROIs, e.g. the tumor, for therapy planning. Final therapy planning will be performed based on these segmentation data in the following MRgFUS therapy session. In addition, the developed software should help to evaluate the therapy success, by synchronization and display of pre-therapeutic, therapy and follow-up image data including the therapy plan and thermal dose information. In this ongoing project, the first stand-alone prototype was completed and will be clinically evaluated.

    While bariatric surgery leads to significant prevention and improvement of type 2 diabetes, patients may rarely develop diabetes after bariatric surgery. The aim of this study was to determine the incidence and the characteristic of new-onset diabetes after bariatric surgery over a 17-year period at our institution. Non-diabetic patients who underwent bariatric surgery at a single academic center (1997-2013) and had a postoperative glycated hemoglobin (HbA1c) ≥ 6.5%, fasting blood glucose (FBG) ≥ 126 mg/dl, or positive glucose tolerance test were identified and studied. Out of 2263 non-diabetic patients at the time of bariatric surgery, 11 patients had new-onset diabetes in the median follow-up time of 9 years (interquartile range [IQR], 4-12). Bariatric procedures performed were Roux-en-Y gastric bypass (n = 7), adjustable gastric banding (n = 3), and sleeve gastrectomy (n = 1). The median interval between surgery and diagnosis of diabetes was 6 years (IQR, 2-9). At the last follow-up, the median HbA1c and FBG values were 6.3% (IQR, 6.1-6.5) and 95 mg/dl (IQR, 85-122), respectively. Possible etiologic factors leading to diabetes were weight regain to baseline (n = 6, 55%), steroid-induced after renal transplantation (n = 1), pancreatic insufficiency after pancreatitis (n = 1), and unknown (n = 3). De novo diabetes after bariatric surgery is rare with an incidence of 0.4% based on our cohort. Weight regain was common (> 50%) in patients who developed new-onset diabetes suggesting recurrent severe obesity as a potential etiologic factor. All patients had good glycemic control (HbA1c ≤ 7%) in the long-term postoperative follow-up.

    PurposeThis study was designed to assess the clinical outcomes of patients treated by vertebral augmentation with nitinol endoprosthesis (VNE) to treat painful vertebral compression fractures.MethodsForty patients with one or more painful osteoporotic VCF, confirmed by MRI and accompanied by back-pain unresponsive to a minimum 2 months of conservative medical treatment, underwent VNE at 42 levels. Preoperative and postoperative pain measured with Visual Analog Scale (VAS), disability measured by Oswestry Disability Index (ODI), and vertebral height restoration (measured with 2-dimensional reconstruction CT) were compared at last follow-up (average follow-up 15 months). Cement extravasation, subsequent fractures, and implant migration were recorded.ResultsLong-term follow-up was obtained in 38 of 40 patients. Both VAS and ODI significantly improved from a median of 8.0 (range 5–10) and 66 % (range 44–88 %) to 0.5 (range 0–8) and 6 % (range 6–66 %), respectively, at 1 year (p < 0.0001). Vertebral height measurements comparing time points increased in a statistically significant manner (ANOVA, p < 0.001). Overall cement extravasation rate was 9.5 %. Discal and venous leakage rates were 7.1 and 0 % respectively. No symptomatic extravasations occurred. Five of 38 (13.1 %) patients experienced new spontaneous, osteoporotic fractures. No device change or migration was observed.ConclusionsVNE is a safe and effective procedure that is able to provide long-lasting pain relief and durable vertebral height gain with a low rate of new fractures and cement leakages.

    Tumors of the neck of the pancreas may involve the superior mesenteric and portal veins as well as the termination of the splenic vein. This presents a difficult problem since the pancreas cannot be transected through the neck as is standard in a Whipple procedure. Here, we present our method of resecting such tumors, which we term "Whipple at the Splenic Artery (WATSA)". The superior mesenteric and portal veins are isolated below and above the pancreas, respectively. The pancreas and splenic vein are divided just to the right of the point that the splenic artery contacts the superior border of the pancreas. This plane of transection is approximately 2 cm to the left of the pancreatic neck and away from the tumor. The superior mesenteric artery is cleared from the left side of the patient. With the specimen remaining attached only by the superior mesenteric and portal veins, these structures are clamped and divided. Reconstruction is performed with or without a superficial femoral vein graft. The splenic vein is not reconstructed. Ten cases have been performed to date without mortality. We have previously shown that the pattern of venous collateral development following occlusion of the termination of the splenic vein in the manner described is not similar to that of cases of sinistral (left sided) portal hypertension. Whipple at the splenic artery (WATSA) is a safe method for resection of tumors of the neck of the pancreas with vein involvement. It should be performed in high-volume pancreatic surgery centers.

    The purpose of this study is to compare the retropubic tension-free vaginal tape (TVT) procedure with the inside-out transobturator approach (TVT-O). Multicenter randomized controlled trial. One hundred forty-nine patients were randomly allocated to either TVT (n = 75) or TVT-O (n = 74). Interview, medical examination, pain scores, success rates, and quality of life assessment were recorded pre-operatively, and 2, 6, 12, and 24 months post-operatively. One hundred forty-nine patients underwent surgery, and 132 completed a 24-month follow-up. Bladder injury rate was 5% (4/75) in the TVT group and 2% (2/74) in the TVT-O group (p = 0.68). There was no significant difference between the two groups, concerning overall cure rate and the patients' satisfaction rate at 24 months follow-up. The range of mean pain scores was significantly higher after the TVT-O procedure post-operatively but not at 24 months follow-up. TVT and TVT-O procedures both have an outcome associated with an increase in quality of life with no significant differences in satisfaction rates at 2 years follow-up.

    Postoperative fluid collection due to pancreatic leak is the most frequent complication after pancreatic surgery. Endoscopic ultrasound (EUS)-guided drainage of post-pancreatic surgery fluid collection is the gold standard procedure; however, data on outcomes of this procedure are limited. The primary endpoint of our study was relapse over longterm followup, and the secondary endpoint was the efficiency and safety of EUS-guided drainage of post-pancreatic surgery fluid collection. This retrospective study was conducted at a single center from December 2008 to April 2016. Global morbidity was defined as the occurrence of an event involving additional endoscopic procedures, hospitalization, or interventional radiologic or surgical procedures. EUS-guided drainage was considered a clinical failure if surgery was required to treat a relapse after stent removal. Fortyone patients were included. The technical success rate was 100%. Drainage was considered a clinical success in 93% (39/41) of cases. Additionally, 19 (46%) complications were identified as global morbidity. The duration between surgery and EUS-guided drainage was not a significantly related factor for morbidity rate (P = 0.8); however, bleeding due to arterial injuries (splenic artery and gastroduodenal artery) from salvage drainage procedures occurred within 25 days following the initial surgery. There was no difference in survival between patients with and without complications. No relapse was reported during the followup (median: 44.75 months; range: 29.24 to 65.74 months). EUSguided drainage for post-pancreatic surgery fluid collection was efficient with no relapse during longterm followup. Morbidity rate was independent of the duration between the initial surgery and EUS-guided drainage; however, bleeding risk was likely more important in cases of early drainage.

    Background and purpose: In patients with Hodgkin's disease treated by radiotherapy with a moderate total dose and a low (mean) fraction dose to the heart, the risk of ischemic heart disease was investigated during long-term follow-up.Materials and methods: The medical records of 258 patients treated in the period 1965-1980 with radiotherapy alone as the primary treatment were reviewed. The median follow-up was 14.2 years (range 0.7-26.2). The mean total dose and fraction dose to the heart were 37.2 Gy (SD 2.9) and 1.64 Gy (SD 0.09), respectively. The impact on the development of ischemic heart disease of treatment-related parameters, such as the applied (fraction) dose, irradiation technique (one or two fields per day), and chemotherapy in case of a relapse, was investigated. The incidence of ischemic heart disease in this patient population was compared with the expected incidence based on gender, age and calendar period-specific data for the Dutch population.Results: Thirty-one patients (12%) experienced ischemic heart disease (actuarial risk at 20-25 years: 21.2% (95% C.I. 15-30). Twenty-five of them were hospitalized. When compared with the expected incidence, the relative risk (RR) of hospital admission for ischemic heart disease was 2.7 (95% C.I. 1.7-4.0). There were 12 deaths (4.7%) due to ischemic myocardial or sudden death (actuarial risk at 25 years: 10.2% (95% C.I. 5.3-19), compared to 2.3 cases that were expected to have died from these causes, yielding a standardized mortality ratio (SMR) of 5.3 (95% C.I. 2.7-9.3). Gender (male), pretreatment cardiac medical history and increasing age appeared to be the only significant factors for the development of ischemic heart disease.Conclusions: Despite the moderate total dose and the low (mean) fraction dose to the heart, the observed incidence of ischemic heart disease is high, especially after long follow-up periods. Treatment related cardiac disease in patients treated for Hodgkin's disease has only been

    Full Text Available Purpose: To identify social factors associated with delayed follow-up in South Indian patients with diabetic retinopathy (DR and to study DR progression during the delayed follow-up period. Materials and Methods: In this cross-sectional study, 500 consecutive patients with DR returning after greater than twice the advised follow-up period were identified from a tertiary referral center in South India. A previously validated 19-item questionnaire was administered to study patients to assess causes for the follow-up delay. Patient demographics, DR status, and treatment plan were recorded at the study visit and the visit immediately before the delay. The eye with the most severe disease was included in the analysis. Results: Complete data were available for 491 (98.2% patients. Among these, 248 (50.5% cited “my eyes were okay at the time,” 201 (41.0% cited “no attender to accompany me,” and 190 (38.6% cited “financial cost” as causes of the follow-up delay. Those with vision-threatening DR (VTDR, n = 233 predominantly reported “financial cost” (47% vs. 32%, P= 0.001, whereas those with non-VTDR more frequently reported “my eyes were okay at the time” (58% vs. 42%, P= 0.001. Evidence of disease progression from non-VTDR to VTDR was seen in 67 (26% patients. Almost 1/3rd (29% of patients who were previously advised regular examination required additional intervention. Conclusion: Many patient-level factors affect poor compliance with follow-up in DR, and these factors vary by disease severity. Targeting these barriers to care through patient education and clinic procedures may promote timely follow-up and better outcomes in these patients.

    Osteochondral allograft (OCA) transplantation is a useful alternative for treatment of posttraumatic ankle arthritis in young patients but has a relatively high failure rate and further procedures are often required. The purpose of this study was to evaluate outcomes of patients who underwent revision OCA transplantation of the ankle after failed primary OCA transplantation. Twenty patients underwent revision OCA transplantation of the ankle between 1988 and 2015. Mean age was 44 years, 55% (11 of 20) were female. The mean time from primary to revision OCA was 3.0 ± 1.7 years. All patients had a minimum follow-up of 2 years. Outcomes included the American Academy of Orthopaedic Surgeons Foot and Ankle Module (AAOS-FAM) and questionnaires evaluating pain and satisfaction. Failure of the revision OCA was defined as a conversion to arthroplasty, arthrodesis, or amputation. Ten of 20 ankles required further surgery, of which 30% (6 of 20) were considered OCA revision failures (4 arthrodeses, 1 arthroplasty, and 1 amputation). The mean time to failure was 6.7 (range, 0.6-13.1) years. Survivorship of the revision OCA was 84% at 5 years and 65% at 10 years. The 14 patients with grafts remaining in situ had an average follow-up of 10.3 years; mean AAOS-FAM Core Score was 70.5 (range, 42.3-99). Of the patients who answered the follow-up questions, 4 of 7 reported moderate to severe pain, and 5 of 12 were satisfied with the results of the procedure. Although the results of revision ankle OCA transplantation are not inferior to primary OCA transplantation, the high rates of persistent pain, further surgery, and graft failure suggest that the indications for OCA as a revision procedure should be carefully evaluated, with proper patient selection. Considering the treatment alternatives, revising a failed OCA transplantation can be a useful treatment option, especially for young and active patients who wish to avoid arthrodesis or arthroplasty.

    To evaluate the reliability of the procedure T1-201 total body scintigraphy was performed in 294 patients (449 studies) after total thyroidectomy for thyroid carcinoma. Results were correlated with I-131-scintigraphy and tumor-marker levels (Tgb or Calcitonin/CEA). T1-201 total body scintigraphy was negative in 196 patients with no evidence of disease. T1-201-scintigraphy correctly detected tumor localizations in 24 of 30 patients with I-131-positive metastases. In 28 patients T2-201 total body scintigraphy revealed metastases which did not concentrate I-131. Histology/cytology confirmed thyroid carcinoma metastases in 16 patients and other pathology in 5 cases. 9 of 18 patients with medullary thyroid carcinoma (I-131-negative) had elevated Calcitonin/CEA-levels. The T1-201 scintigram was positive in 8 of these patients. Comparison of T1-201, I-131 and tumor markers showed that only combined use of these parameters provide complete reliability. The authors conclude that T1-201 total body scintigraphy is useful in follow up of thyroid carcinoma, especially when a discrepancy of the other parameters exists and particularly in medullary carcinoma. In long term follow up of patients who are unsuspected of disease after successful therapy for thyroid carcinoma one can rely on T1-201 total body scintigraphy in combination with tumor marker assays

    The Sloan Digital Sky Survey-II Supernova Survey has identified a large number of new transient sources in a 300 deg{sup 2} region along the celestial equator during its first two seasons of a three-season campaign. Multi-band (ugriz) light curves were measured for most of the sources, which include solar system objects, galactic variable stars, active galactic nuclei, supernovae (SNe), and other astronomical transients. The imaging survey is augmented by an extensive spectroscopic follow-up program to identify SNe, measure their redshifts, and study the physical conditions of the explosions and their environment through spectroscopic diagnostics. During the survey, light curves are rapidly evaluated to provide an initial photometric type of the SNe, and a selected sample of sources are targeted for spectroscopic observations. In the first two seasons, 476 sources were selected for spectroscopic observations, of which 403 were identified as SNe. For the type Ia SNe, the main driver for the survey, our photometric typing and targeting efficiency is 90%. Only 6% of the photometric SN Ia candidates were spectroscopically classified as non-SN Ia instead, and the remaining 4% resulted in low signal-to-noise, unclassified spectra. This paper describes the search algorithm and the software, and the real-time processing of the SDSS imaging data. We also present the details of the supernova candidate selection procedures and strategies for follow-up spectroscopic and imaging observations of the discovered sources.

    We examined the prevalence of venous obstruction in 12 newborns and infants with permanent endovenous ventricular pacing, clinically, and by ultrasonographic assessment of hemodynamics (spontaneity, phasicity, velocity, and turbulence of flow) and morphologic parameters (compressibility, wall thickness, and thrombus presence). All implantations of single ventricular unipolar endovenous steroid leads, were performed via cephalic vein, and pacemakers were placed in subcutaneous pocket in right prepectoral region. After the vascular surgeon has carefully examined all children for presence of venous collaterals in the chest wall, morphologic and hemodynamic parameters of the subclavian, axillary, and internal jugular veins, were assessed by linear-array color Doppler. Lead capacity (LC) was calculated for each patient. Mean age of patients at implant was 6.2 months (range 1 day-12 months), mean weight 6.5 kg (range 2.25-10 kg), and mean height 60.9 cm (range 48-78 cm). Mean LC was 1.99 (range 1.14-3.07). Total follow-up was 1023 and mean follow-up 85.2 pacing months (range 3-156). No clinical signs of venous obstruction were observed. Mild stenosis (20%) of subclavian vein was found by color Doppler in 2/12 patients. Both had adequate lead diameter for body surface. Permanent endovenous pacing is a feasible procedure, even in children of body weight less than 10 kg, with quite acceptable impact on venous system patency.

    Purpose: Intraindividual comparison of quantitative malignant liver tumor response analysis using computed tomography. The RECIST and WHO evaluation results were compared to the volumetry results. Materials and method: Consecutive CT follow-up investigations (portal-venous phase, collimation 3 mm, increment 2 mm) of 82 patients were analyzed retrospectively. The median interval was 56 (30 - 455) days. The patients showed a total of 198 (median 3, range 1 - 5) malignant liver lesions. The evaluation was performed by 2 radiologists using the OncoTREAT software (Mevis) in consensus. The results were classified according to RECIST (Response Evaluation Criteria in Solid Tumors, stable disease: - 30 % to + 20 %) and WHO (stable: - 50 % to + 25 %) and compared to the volumetric analysis (stable: - 65 % to + 44 %). Both the continual follow-up changes and the classified results (complete and partial remission, no change and progression) were analyzed. Results: The classified RECIST and WHO results agreed with the volumetric analysis in 71/82 (87 %) of cases κ RECIST = 0,699, κ WHO = 0,741. This included different patients thus showing the agreement between the RECIST and WHO evaluations in 68/82 (83 %) cases (κ = 0,656). The estimation of the relative tumor development was clearly different in all procedures. Relative tumor changes are not directly comparable because of underlying one-, two- and three-dimensional structures. (orig.)

    To present the long-term outcomes of appendicovesicostomy using the Mitrofanoff principle for end-stage Wolfram bladder dysfunction as an alternative to clean intermittent self-catheterization (CIC) per urethra mainly following blindness. Twelve Wolfram patients presenting with bilateral hydroureteronephrosis and advanced bladder dysfunction were included in this study. All patients were managed initially by CIC per urethra. All of these patients became blind during follow-up and were unable to perform urethral CIC independently. Out of these patients, six patients agreed to proceed to appendicovesicostomy. Appendicovesicostomy urinary diversion using the Mitrofanoff principle was performed in these six blind patients. The rest of the patients stopped CIC or performed CIC irregularly. Severe hydroureteronephrosis and large bladders were found in all patients prior to intervention. All patients were able to conduct CIC independently through the stoma and maintained overnight bladder free drainage. In all patients with urinary diversion and CIC, the hydroureteronephrosis was reduced and renal function returned to normal. However, the non-intervention group ended with different degrees of progressive renal failure with three mortalities during the follow-up. We suggest appendicovesicostomy as a safe and lifesaving procedure for long-term management of bladder dysfunction in Wolfram syndrome particularly after progression to blindness.

    This report comprises an analysis of the results of 201 laparoscopic sterilizations performed at Beaufort County Hospital for an 18-month period and the follow-up of these patients for 2 years. Patients ranged in age from 19-45 years (mean, 32.2). Average parity was 2.7, ranging from 0-14. Of the 201 patients, 173 were white and 28 black. 1% of the sterilization attempts failed (n=2 cases). 1 failure occurred in a woman with a previous appendectomy, due to adhesions, and the other patient failure had a history of abdominal gunshot wounds in which she sustained an omental laceration; both women underwent laparotomy and then were sucessfully sterilized via Pomeroy technique. During the 2-year follow-up, 144 of the original 201 were available. 2 of these subjects subsequently became pregnant. 17 gynecologic procedures were later performed on 15 patients. 6 patients had dilatation and curettage for menstrual irregularity, 2 of whom underwent hysterectomy. 6 other patients also had hysterectomy, making a total of 8 of 201 patients. Symptomatic pelvic relaxation (3), severe dysplasia of the cervix (1), a large ovarian cyst with dysmenorrhea and dyspareunia (1), and severe dysmenorrhea and menorrhagia (1) were the other indications for hysterectomy among these sterilization patients. The author points out that the rate of 8 hysterectomies per 201 cases in only 2 years points to an even higher rate of hysterectomy subsequent to laparoscopic sterilization than previously suspected.

    Full Text Available This is a retrospective, observational study comprising of eight patients with isolated rupture of the sinus of Valsalva (RSOV who underwent transcatheter device closure. The mean age of presentation was 32.8 ± 10.0 years. New York Heart Association (NYHA class at the time of presentation was II (six patients and III (two patients. The RSOVs were all closed using a patent ductus arteriosus device. The mean procedural time was 42.3 ± 5.4 minutes, while the fluoroscopic time was 24.5 ± 6.9 minutes. All had complete closure of the shunt. The average hospital stay was 2.9 ± 1.1 days. There were no major complications. The patients were followed up for a mean of 11.3 ± 4.1 months. At the time of the last follow up all the patients were in NYHA class I. We conclude that in the short term, transcatheter closure of isolated RSOV is a viable alternative to surgical repair.

    To evaluate clinical outcomes, pain, and patient satisfaction following revision hip arthroscopy with a minimum 2-year follow-up. From April 2008 to October 2011, data were prospectively collected on all patients undergoing revision hip arthroscopy. All patients were assessed pre- and postoperatively with 4 patient-reported outcome (PRO) measures: the modified Harris hip score (mHHS), nonarthritic hip score (NAHS), hip outcome score-activities of daily living (HOS-ADL), and hip outcome score-sport-specific subscales (HOS-SSS). Pain was estimated on the visual analog scale (VAS). Patient satisfaction was measured on a scale from 0 to 10. The number of patients who underwent subsequent revision arthroscopy or total hip arthroplasty during the study period is also reported. Eighty-seven patients underwent revision hip arthroscopy during the study period. Seventy (80.5%) patients were included in our study. Average follow-up time was 28 months (range, 20 to 47.4 months). In terms of residual femoroacetabular impingement morphology, 45.7% of patients had preoperative alpha angles ≥ 55°, and 7.14% of patients had a lateral center-edge angle ≥ 40°. The score improvement from preoperative to 2-year follow-up was 57.84 to 73.65 for mHHS, 62.79 to 83.04 for HOS-ADL, 37.33 to 54.93 for HOS-SSS, and 55.65 to 70.79 for NAHS. VAS decreased from 6.72 to 4.08. All scores demonstrated statistically significant improvement (P arthroscopy during the study period. We found an overall minor complication rate of 10%. Revision hip arthroscopy for all procedures performed on aggregate has improved clinical outcomes for all PROs, high survivorship, and high patient satisfaction scores at short-term follow-up. Patients should be counseled regarding the potential progression of degenerative change leading to arthroplasty and the potential for revision surgery. Level IV retrospective case series.

    A patient dose survey was carried out measuring the kerma-area product (KAP) values during radiological evaluation in the follow-up of bariatric surgery. The procedures were performed by three radiologists to adjust laparoscopic gastric bands and to detect postoperative complications after Roux-en-Y gastric bypass procedures to treat morbid obesity. Total fluoroscopy time, exposure factors and the overall contribution of fluoroscopy to the accumulated KAP value were recorded. The median KAP values were used to estimate organ doses and effective dose to a standard patient; the radiation risk associated with the procedures was also evaluated. The doses were smaller for one of the three radiologists, owing to a more appropriate beam collimation and a reduction of the screening time. The KAP values ranged from 1.6 to 7.1 Gy cm 2 for the laparoscopic adjustable gastric banding management, and from 3.0 and 8.3 Gy cm 2 for the radiological examinations after gastric bypass. As a whole, the effective doses associated to these procedures were between 0.5 and 2.7 mSv. The organs receiving the highest doses were not only breast, stomach, pancreas and liver, but also lungs, owing to of their high radiosensitivity, significantly contributed to the effective dose.

    To evaluate the feasibility and effectiveness of endovascular repair for blunt popliteal arterial injuries. A retrospective analysis of seven patients with clinical suspicion of popliteal arterial injuries that were confirmed by arteriography was performed from September 2009 to July 2014. Clinical data included demographics, mechanism of injury, type of injury, location of injury, concomitant injuries, time of endovascular procedures, time interval from trauma to blood flow restoration, instrument utilized, and follow-up. All patients were male (mean age of 35.9 ± 10.3 years). The type of lesion involved intimal injury (n = 1), partial transection (n = 2), complete transection (n = 2), arteriovenous fistula (n = 1), and pseudoaneurysm (n = 1). All patients underwent endovascular repair of blunt popliteal arterial injuries. Technical success rate was 100%. Intimal injury was treated with a bare-metal stent. Pseudoaneurysm and popliteal artery transections were treated with bare-metal stents. Arteriovenous fistula was treated with bare-metal stent and coils. No perioperative death and procedure-related complication occurred. The average follow-up was 20.9 ± 2.3 months (range 18–24 months). One patient underwent intra-arterial thrombolysis due to stent thrombosis at 18 months after the procedure. All limbs were salvaged. Stent migration, deformation, or fracture was not found during the follow-up. Endovascular repair seems to be a viable approach for patients with blunt popliteal arterial injuries, especially on an emergency basis. Endovascular repair may be effective in the short-term. Further studies are required to evaluate the long-term efficacy of endovascular repair.

    Neoplasms of the heart are rare. Usually asymptomatic on the early stage are diagnosed incidentally. Among primary heart neoplasms the most often benign tumors are diagnosed--mostly myxomas, whereas the majority of malignant heart tumors are sarcomas. The aim of this paper was to present heart tumors diagnosed in the cardiology department, their symptoms, used diagnostic tests and therapy and to show after therapy quality of life changes. There were 18 patients included to the study, whom during hospitalization in the cardiology department heart tumors were diagnosed. There were 11 women and 7 men, aged from 33- to 76-years-old (mean 60,5 years). To all of the patients medical interview, physical examination, EKG, UCG and laboratory test were performed. Additionally in some cases computed tomography or magnetic resonance imaging of the chest and coronary angiograms were done. Based on the diagnostic tests results the patients were qualified to conservative or surgical treatment. Among 18 heart tumor patients in 12 cases primary benign tumors were diagnosed (66,6%), 1 patient had primary malignant tumor (5,5%), there were 3 cases of metastatic tumors (16,6%) and 2 patients with non-neoplasmic tumors--clots (11,1%). From 18 subjects with heart tumor 3 patients died because of advanced stage of neoplasmic disease and presence of metastatic tumors in the heart. Results of the study show, that heart tumors, regardless of development of diagnostic tests, are still diagnosed too late. The study group follow-up proved, that early diagnosis and proper heart tumor treatment prevented complications and improved the quality of life. It is worth to emphasize, that coronary angiogram in some cases allowed to diagnose coronary artery disease, to treat heart tumor and to perform coronary artery by-pass grafting simultaneously.

    Background: The EucaTax stent (EUPES) is a coronary stent with biodegradable polymer and camouflage coating that has been developed to promote the complete elution of drugs and decrease the risk of late complications. The aim of this study was to evaluate the efficacy and safety of the double-coated EUPES in patients with stable angina versus sirolimus-eluting stent CYPHER (SES) with permanent polymer coating. Methods and Materials: The study included consecutive patient with at least 70% de novo coronary lesions in one or two native coronary arteries and who had undergone the coronary stenting using either EUPES or SES. We evaluated the 2-year major adverse cardiac events (MACE) rates, including total death (cardiac, non-cardiac), myocardial infarction (MI), target lesion revascularisation (TLR) and stent thrombosis. Results: Between 2006 and 2009 this observational, prospective, single centre study included 602 patients (282 with EUPES and 320 with SES). At 2 years, the rates of TLR (16.3% versus 6.25%; p = 0.0001) and MACE (18.4% versus 7.8%; p = 0.001) were significantly higher in the EUPES than in the SES group. The rate of TLR was significantly higher in the EUPES group compared with SES group in stenting of artery with a diameter less than 3 mm, using stent length more than 18 mm, as well as when the residual stenosis was more than 12%. Conclusions: We found that EUPES was inferior to SES during the 2-year follow-up with respect to rates of MACE and TLR that were significantly higher in the EUPES than in the SES group

    Background: The EucaTax stent (EUPES) is a coronary stent with biodegradable polymer and camouflage coating that has been developed to promote the complete elution of drugs and decrease the risk of late complications. The aim of this study was to evaluate the efficacy and safety of the double-coated EUPES in patients with stable angina versus sirolimus-eluting stent CYPHER (SES) with permanent polymer coating. Methods and Materials: The study included consecutive patient with at least 70% de novo coronary lesions in one or two native coronary arteries and who had undergone the coronary stenting using either EUPES or SES. We evaluated the 2-year major adverse cardiac events (MACE) rates, including total death (cardiac, non-cardiac), myocardial infarction (MI), target lesion revascularisation (TLR) and stent thrombosis. Results: Between 2006 and 2009 this observational, prospective, single centre study included 602 patients (282 with EUPES and 320 with SES). At 2 years, the rates of TLR (16.3% versus 6.25%; p = 0.0001) and MACE (18.4% versus 7.8%; p = 0.001) were significantly higher in the EUPES than in the SES group. The rate of TLR was significantly higher in the EUPES group compared with SES group in stenting of artery with a diameter less than 3 mm, using stent length more than 18 mm, as well as when the residual stenosis was more than 12%. Conclusions: We found that EUPES was inferior to SES during the 2-year follow-up with respect to rates of MACE and TLR that were significantly higher in the EUPES than in the SES group.

    Overexposure to radioactive sources used in radiotherapy or industrial radiography may result in severe health consequences. This report assesses the initial clinical status and the medical and psychological long-term follow-up of two radiation accident patients from Peru during the mid-to-late 1990's: one patient exposed to a radiotherapy 60 Co source in Arequipa, the other patient to a 192 Ir source in Yanango. Commonalities and differences are described. The main causes in both accidents were human error and the failure to apply appropriate safety guidelines and standard operating procedures. Education and training of the personnel working with radiation sources are essential to prevent accidents. The experience gained from the medical management of the two patients is valuable for future treatment of such patients. (authors)

    Conclusions: Adding phone call contacts to email reminders and monetary incentives did increase follow-up rates. However, the rate of response to follow-up was low and the number of phone calls required to achieve one completed follow-up raises concerns about the utility of adding phone calls. We also discuss difficulties with using financial incentives and their implications.

    Aim: Sublingual (SL) nitroglycerin administered before radial artery puncture can improve cannulation success and decrease the incidence of radial artery spasm (RAS) compared with intra-arterial (IA) nitroglycerin in transradial procedures. Methods: Patients undergoing diagnostic transradial angiography were randomized to IA (200 mcg) or SL (400 mcg) nitroglycerin. Primary endpoints were puncture time and puncture attempts. Secondary endpoint was the incidence of RAS. Results: Total of 101 participants (mean age 60 ± 11 years, 53% male) were randomized (51 in IA and 50 in SL groups). Puncture time (50 [36–75] vs 50 [35–90] sec), puncture attempts (1.18 ± 0.48 vs 1.20 ± 0.49), multiple punctures (13.7 vs 16.0%) and RAS (19.6 vs 24.0%) were not statistically different between IA vs SL groups respectively. A composite endpoint of all adverse events related to transradial angiography (multiple punctures, RAS, access site crossover, hypotension/bradycardia associated with nitroglycerin and radial artery occlusion) was very similar in IA vs SL groups (39 vs 40%, respectively). However puncture time was significantly longer with SL nitroglycerin in patients < 1.65 m height (47 [36–66] vs 63 [41–110] sec, p = 0.042). Multiple punctures seemed higher with SL nitroglycerin in patients with diabetes (0 vs 30%, p = 0.028) or in patients < 1.65 m height (7.4 vs 25%, p = 0.085). Likewise, RAS with SL nitroglycerin seemed more frequent in smokers compared to IA nitroglycerin (0 vs 27%, p = 0.089). Conclusions: SL nitroglycerin was not different from IA nitroglycerin in terms of efficiency and safety in overall study population. However it may be inferior to IA nitroglycerin in certain subgroups (shorter individuals, diabetics and smokers). - Highlights: • Improvement in radial artery puncture time and success with subcutaneous nitrate was reported. • Giving nitrate sublingually may have vasodilation along entire length of radial artery and may prevent RAS

    Primary angiitis of the central nervous system (PACNS) is an extremely rare vasculitis of unknown etiology. The purpose of this study was to describe the initial and follow-up magnetic resonance (MR) imaging features of the tumor-mimicking PACNS. We retrospectively reviewed a total of 21 initial and follow-up brain MR images obtained in four patients with biopsy-proven PACNS mimicking brain tumor on MR images during the periods from 1 to 8.1 years. In the initial study, diffusion-weighted imaging (DWI; n=4), MR angiogram (n=4), conventional catheter angiogram (n=3), perfusion MR (n=1), and computed tomography (n=1) and proton MR spectroscopy (MRS; n=2) were included. The lesions of the brain were qualitatively assessed in terms of location, number, size, shape, signal intensity, absence or presence of hemorrhage, enhancement pattern, and changes on the follow-up studies. Initially, the lesion manifested as single suprasellar (n=1) and frontal hemispheric (n=1) mass and as multiple-enhancing lesions in the unilateral supratentorial hemisphere (n=2). A patient showed steno-occlusive lesions in the internal carotid and middle cerebral arteries. DWI, perfusion imaging, and MRS revealed inconsistent findings among the patients. On the follow-up studies, a patient had two relapses but there was either significant decrease in size and extent or disappearance of the lesions with immunosuppressive therapy in all patients. Tumor-mimicking PACNS shows variable features on initial MR images but shows good responses to appropriate immunosuppressive therapy on follow-up MR images. (orig.)

    The purpose of this study was to provide 24-month follow-up on surgical success and safety of an ab interno circumferential 360-degree trabeculotomy. Chart review of patients who underwent a gonioscopy-assisted transluminal trabeculotomy (GATT) procedure was performed by 4 of the authors (D.S.G., O.S., R.L.F., and D.G.G.). The surgery was performed in adults with various types of open-angle glaucoma with preoperative intraocular pressures (IOPs) of ≥18 mm Hg. In total, 198 patients aged 24 to 89 years underwent the GATT procedure with at least 18 months follow-up. Patients with primary open-angle glaucoma had an average IOP decrease of 9.2 mm Hg at 24 months with an average decrease of 1.43 glaucoma medications. The mean percentage of IOP decrease in these primary open-angle glaucoma groups at 24 months was 37.3%. In secondary open-angle glaucoma, at 24 months there was an average decrease in IOP of 14.1 mm Hg on an average of 2.0 fewer medications. The mean percentage of IOP decrease in the secondary open-angle glaucoma groups at 24 months was 49.8%. The cumulative proportion of failure at 24 months ranged from 0.18 to 0.48, depending on the group. In all 6 study groups, at all 5 postoperative time points (3, 6, 12, 18, and 24 mo) the mean IOP and reduction in glaucoma medications was significantly reduced from baseline (P<0.001) with the exception of one time point. The 24-month results demonstrate that GATT is relatively safe and effective in treating various forms of open-angle glaucoma. The long-term results for GATT are relatively equivalent to those previously reported for GATT and ab externo trabeculotomy studies.

    Objectives: To evaluate the feasibility and efficacy of robotic-assisted laparoscopic pyeloplasty. Laparoscopic pyeloplasty has been shown to have a success rate comparable to that of the open surgical approach. However, the steep learning curve has hindered its acceptance into mainstream urologic practice. The introduction of robotic assistance provides advantages that have the potential to facilitate precise dissection and intracorporeal suturing. Methods: A total of 50 patients underwent robotic-assisted laparoscopic dismembered pyeloplasty. A four-trocar technique was used. Most patients were discharged home on day 1, with stent removal at 3 weeks. Patency of the ureteropelvic junction was assessed in all patients with mercaptotriglycylglycine Lasix renograms at 1, 3, 6, 9, and 12 months, then every 6 months for 1 year, and then yearly. Results: Each patient underwent a successful procedure without open conversion or transfusion. The average estimated blood loss was 40 ml. The operative time averaged 122 minutes (range 60 to 330) overall. Crossing vessels were present in 30% of the patients and were preserved in all cases. The time for the anastomosis averaged 20 minutes (range 10 to 100). Intraoperatively, no complications occurred. Postoperatively, the average hospital stay was 1.1 days. The stents were removed at an average of 20 days (range 14 to 28) postoperatively. The average follow-up was 11.7 months; at the last follow-up visit, each patient was doing well. Of the 50 patients, 48 underwent one or more renograms, demonstrating stable renal function, improved drainage, and no evidence of recurrent obstruction. Conclusions: Robotic-assisted laparoscopic pyeloplasty is a feasible technique for ureteropelvic junction reconstruction. The procedure provides a minimally invasive alternative with good short-term results.

    'Alive' searches have been used to complement the 'death' searches, in a study of the mortality experience of a cohort of Ontario miners. The purpose has been to develop a way of distinguishing between those cohort members who are 'confirmed' alive at a given time, and those who are 'lost to follow-up'. A total of 30,000 Workers' Compensation Board (WCB) records with valid Social Insurance Numbers (SIN) were used to search the income tax files by computer over two consecutive years (1977 and 1978) representing nearly 27 million tax returns. These tax file searches using SIN numbers have provided information on the procedures to be used in, and likely success of, the corresponding searches of the tax files that could be carried out where the SIN number is not available on the work records. The latter kind of search would have to be based on names, birth dates and such, and would be probabilistic in nature. The results of the study were as follows: After the initial death search, it was found that 7.5% of the cohort had died in Canada and their records were found on the Mortality Data Base. The remaining 92.5% has been 'assumed alive' in the earlier analysis. After the 'alive' follow-up using the income tax file, one was able to confirm that 89.1% of the 'assumed alive' had filed an income tax after the study period. Thus only 3.4% of the cohort remained untraced. Among those there could be an admixture of deaths outside of Canada, persons who have moved outside of Canada and are still alive, and/or persons alive within Canada, but who have not filed an income tax return. This study has indicated that the procedures developed are useful for purposes of 'alive' follow-up, for evaluation of the quality of the Mortality Data Base-cohort death file searches, for improving the accuracy of analytical results of epidemiological studies, and for reducing the cost and labour of resolving doubtful death searches

    The TVT-Secur was introduced in 2006 as a less invasive alternative to retropubic and transobturator suburethral slings. This retrospective cohort study evaluated objective and subjective results in a series of 158 consecutive patients as well as complications and the reoperation rate after TVT-Secur procedure. Between November 2006 and June 2010 a total of 158 patients underwent a TVT-Secur procedure at a single institution. All patients underwent preoperative urodynamic testing. All patients were invited for follow-up including physical examination, urodynamic studies and subjective evaluation. A total of 96 patients (61%) were available for follow-up with a mean follow-up of 29.8 months (range 5-50, median 30). At follow-up, eight (8%) of 96 patients had reoperations for stress incontinence. There were no reoperations for bleeding/hematoma, tape erosions or obstructed micturition and there were no tape erosions or exposures. 29 patients (30%) had a negative cough stress test and 44 patients (46%) subjectively considered themselves "cured". Nine of 43 patients (21%) without urgency symptoms preoperatively developed de novo urgency; 24 of 35 patients (69%) with preoperative urgency complaints were free of urgency symptoms. At 2.4 years, the TVT-Secur appears to have a low adverse events profile but inferior results compared with traditional midurethral slings. Copyright © 2014 Elsevier Ireland Ltd.

    Results of the 10-year prospective follow-up of 59 ischemia patients with stenocardia are presented. Coronarography was made in all the patients whose coronary arteries and collateral blood flow were assessed. The experimental group comprised 37 patients with ischemia and collateral circulatory insufficiency. The control group included 22 patients with effective collateral circulation. The experimental group showed a worse prognosis than did the control one. Myocardial infarction developed in 54 and 27 % of cases, ischemia mortality was 29.7 and 9 % in the experimental and control groups, respectively. Effective collateral circulation is prerequisite of successful surgical myocardial revascularization [ru

  17. Interventional radiology in the diagnosis, management, and follow-up of pseudoaneurysms.

    Arterial wall disruption, as a consequence of inflammation\\/infection, trauma (penetrating or blunt), or iatrogenic causes, may result in pseudoaneurysm formation. Currently, iatrogenic causes are increasing as a result of the growth of endovascular intervention. The frequency of other causes also seems to be increasing, but this may simply be the result of increased diagnosis by better imaging techniques, such as multidetector contrast-enhanced computed tomography. Clinically, pseudoaneurysms may be silent, may present with local or systemic signs, or can rupture with catastrophic consequences. Open surgical repair, previously the mainstay of treatment, has largely been replaced by image-guided occlusion methods. On the basis of an experience of over 100 pseudoaneurysms, treatments at various anatomical sites, imaging modalities used for accurate diagnosis, current changing therapeutic options for pseudoaneurysm management, approved embolization agents, and clinical follow-up requirements to ensure adequate treatment will be discussed. Image-guided direct percutaneous and endovascular embolization of pseudoaneurysms are established treatment options with favorable success rates and minimal morbidity. The pendulum
