CUORE is a cryogenic experiment searching primarily for neutrinoless double decay in 130Te. It will begin data-taking operations in 2016. To monitor the cryostat and detector during commissioning and ...data taking, we have designed and developed Slow Monitoring systems. In addition to real-time systems using LabVIEW, we have an alarm, analysis, and archiving website that uses MongoDB, AngularJS, and Bootstrap software. These modern, state of the art software packages make the monitoring system transparent, easily maintainable, and accessible on many platforms including mobile devices.
While it is well know the usefulness of neurophysiological tests to investigate somatic nervous system of pelvic floor, it is not yet recognized the real efficacy of sympathetic skin response (SSR). ...In the last years we examined more than 1500 patients with different pelvic disorders (age range 7–85 years). All patients were studied with pudendal EMG, SEP, MEP, sacral reflexes. SSR was recorded from skin of sacral area (i.e. penis or mons pubis, perineal area, perianal area according to symptoms), applying random single square pulses at wrist or supraorbital region. SSR latency and amplitude were measured and the results were compared by mean age with those of control group. We observed alterations in latency and/or amplitude and in some cases SSR changes were the only present abnormality. We have also observed that it is important to differentiate anterior from posterior perineal area in SSR recording. SSR test may be a useful tool to investigate autonomic sacral involvement, because until now it is the only test to explore autonomic system. In our experience SSR is always present, in absence of pathology, so it could become a standard investigation for clinical routine of patients with sacral disorders.
Endoaneurysmorrhaphy with intraluminal graft placement, described by Creech, is the gold standard for abdominal aortic aneurysm (AAA) repair. Endovascular aneurysm repair has gained popularity for ...its minimal invasiveness and satisfying short-term results, but there are still many concerns about the long-term success of the procedure. Since 1998, laparoscopic surgery has been proposed for AAA treatment. The potential benefits of a minimally invasive procedure reproducing the endoaneurysmorrhaphy results over time have been advocated. In our experience, hand-assisted laparoscopic surgery (HALS) has been routinely used for the open-surgery transperitoneal/retroperitoneal approach and for endovascular aneurysm repair. After 4 years, we are able to define the early and middle-term results of such laparoscopic-assisted treatment.
From October 2000 to March 2004, 604 consecutive nonurgent AAAs were treated at our institution. Of these, 122 (20.2%) were treated by HALS. Exclusion criteria for HALS were hostile abdomen (previous major abdominal or aortic surgery), bilateral diffuse common iliac and/or hypogastric aneurysms, massive aortoiliac calcifications, and severe cardiac (ejection fraction <35%) and respiratory (Po2 <60 mm Hg or carbon dioxide >50 mm Hg) insufficiency. Juxtarenal and proximal iliac aneurysms were not a contraindication, nor was obesity. In all patients, we performed a minilaparotomy (7-8 cm) both for laparoscopic hand-assisted dissection and for endoaneurysmorrhaphy. All perioperative data were prospectively recorded. Follow-up consisted of ultrasonography and clinical evaluation after 6 and 12 months and then every year after surgery.
The mean laparoscopic and total operative times were respectively 64 ± 32 minutes and 257 ± 70 minutes, the mean aortic cross-clamping time was 76 ± 26 minutes, and the mean autotransfused blood volume was 1136 ± 711 mL. The overall mortality and morbidity were respectively 0% and 12.2%. Morbidity was surgery related in only two cases (bleeding from an ipogastric artery lesion and a leg graft thrombosis). The mean intensive care unit stay was 14.3 ± 13 hours. Oral food intake was resumed after 27.4 ± 15 hours, and patients were discharged after a mean of 4.4 ± 1.7 days. Operative times were not affected by obesity, suprarenal aortic cross-clamping, or aneurysm size. Both concomitant iliac aneurysms and bifurcated graft implantation (related to longer vascular reconstruction) involved significantly longer operative times. The learning curve of the procedure (comparing the first 30 patients with the last 92 patients) led to significantly shorter endoscopic, cross-clamping, and total operative times (P = .000). The mean follow-up was 28.6 ± 16 months. Three incisional hernias and one case of bowel occlusion were detected. All these cases (3.4%) required laparoscopic treatment.
The HALS technique is a safe and minimally invasive treatment for AAA; it is useful for limiting the need for conventional open surgery and reducing the length of hospital stay. Despite the lack of randomized studies, HALS seems to be associated with a better postoperative course than standard open surgery. HALS can also be considered as an equivalent of a well-established procedure and as a bridge between open and total laparoscopic surgery.
An integrated model for ranking scientific publications together with authors and journals recently presented in Bini, Del Corso, Romani, ETNA 2008 is closely analyzed. The model, which relies on ...certain adjacency matrices
H
,
K
and
F
obtained from the relations of citation, authorship and publication, provides the ranking by means of the Perron vector of a stochastic matrix obtained by combining
H
,
K
and
F
. Some perturbation theorems concerning the Perron vector previously introduced by the authors are extended to more general cases and a counterexample to a property previously addressed by the authors is presented. The theoretical results confirm the consistency and effectiveness of our model. Some paradigmatic examples are reported together with some results obtained on a real set of data.
To evaluate the efficacy and safety over a 10-year period of any urological operations required by female patients with spinal cord lesions (SCLs).
Retrospective study of urological surgeries from ...our database performed on females with SCLs from 2001 to 2002. Surgery efficacy for neurogenic lower urinary tract dysfunctions (N-LUTDs) was evaluated by comparing 7-day voiding diaries pre- and post-surgeries, while individual investigations were done pre- and post-surgery to evaluate urological complications. Drawbacks were assessed.
Thirty-eight out of 69 patients underwent one or more urological procedures. Twenty-one out of 42 patients with suprasacral lesions underwent interventions for N-LUTD. The main surgical treatment was endoscopic detrusor infiltration of botulinum-A (Botox 300 UI or Dysport 750 UI) performed 107 times on 15 subjects using aseptic intermittent catheterizations for neurogenic overactive bladder. Mean efficacy duration was 9.2 months. Six females with infrasacral lesions underwent at least one intervention for N-LUTD. Two females in each group underwent tension-free vaginal tape for stress urinary incontinence (SUI), reducing episodes per week of SUI by >90% after 5 years. The most serious urological complication was active vesico-ureteral reflux (VUR) in three patients, treated endoscopically with submucosal injection of Macroplastique. No VUR recurrence was detected during a 6-year follow-up. All bladder stones (five cases) and renal calculi (five cases) were treated with endoscopic transurethrally electrohydraulic lithotripsy and extracorporeal shock-wave lithotripsy, respectively. Overall, no serious drawbacks were observed.
Mini-invasive surgeries were exclusively used to address urological issues in chronic SCL patients.
The maxillary sinus floor elevation procedure has gained popularity with predictable results, and is a safe, acceptable technique for bone augmentation, providing a base for dental implant treatment. ...Faint radiopaque lesions at the base of the maxillary sinus are frequent diagnoses on radiographs and must be identified during dental implant planning. The use of autografts, xenografts, allografts, and alloplasts or a combination between them has been demonstrated to be effective for increasing bone height and bone volume in maxillary sinus. The objective of this study was to evaluate the outcome of subjects with considerable sinus membrane pathology (test group) undergoing maxillary sinus floor augmentation using Platelet Rich Fibrin (PRF) as a filling material, in association with the Bio-Oss and Sint-Oss and simultaneous implant placement in a one-stage surgical procedure. All patients reported no pain to percussion, no sign of tissue suffering to the soft peri-implant tissues, the presence of an optimal primary stability of the inserted implants, and the increase in the peri-implant bone density. No complications were encountered during follow-up periods in these patients, including no negative evolution in the sinusitis and all implants are functioning successfully. In conclusion, the use of PRF and Piezosurgery reduced the healing time, favoring optimal bone regeneration and allowing sinus membrane integrity to be maintained during surgical procedures, according to evidence-based dentistry.
PageRank algorithm plays a very important role in search engine technology and consists in the computation of the eigenvector corresponding to the eigenvalue one of a matrix whose size is now in the ...billions. The problem incorporates a parameter
α
that determines the difficulty of the problem. In this paper, the effectiveness of stationary and nonstationary methods are compared on some portion of real web matrices for different choices of
α
. We see that stationary methods are very reliable and more competitive when the problem is well conditioned, that is for small values of
α
. However, for large values of the parameter
α
the problem becomes more difficult and methods such as preconditioned BiCGStab or restarted preconditioned GMRES become competitive with stationary methods in terms of Mflops count as well as in number of iterations necessary to reach convergence.
