Repeated applications of rendezvous technique combining percutaneous transhepatic biliary drainage (PTBD) with endoscopic retrograde cholangiopancreatography (ERCP) (PE) in patients with recurrent obstructive jaundice have not been reported. The present study aimed to evaluate treatment effects of this technique in patients who previously received the same rendezvous treatment. Repeated PE rendezvous procedure was performed in 27 patients who received the same procedure previously and had recurrent obstructive jaundice. Twenty-two patients were treated by second-time rendezvous procedure and five patients by third-time. The clinical characteristics and therapeutic effects were retrospectively analyzed. By means of repeated rendezvous technique, 26 patients gained access to the bile duct and were successfully implanted new stents, only one failed with stent implantation. Total serum bilirubin level decreased within one week from 221.89 +/- 64.70 micromol/L to 156.0 +/- 32.2 micromol/L in patients with second-time treatment and from 297.07 +/- 109.12 micromol/L to 238.77 +/- 36.81 micromol/L in patients with third-time treatment. There was no severe complications observed that are associated with repeated PE procedure. Rendezvous procedure of PTBD and ERCP could be used repeatedly and effectively for patients who present recurrent obstructive jaundice after ERCP failure.

Pathological proof of malignant in biliary strictures is useful in the preoperative setting as it helps define therapeutic planning and prognosis, and reduces the length of the subsequent surgical intervention. However, it is difficult to obtain. The aim of this study was to evaluate the yield of histological and cytological examination of endobiliary samples obtained during endoscopic retrograde cholangiopancreatography (ERCP). Endobiliary forceps biopsy and brush cytology were performed during ERCP examination in 52 consecutive patients, 36 with malignant and 16 with benign strictures. Histology and cytology turned out to have the same sensitivity (53%). The gain in sensitivity achieved by combining the two techniques was limited, reaching a value of 61%. The specificity, however, was 100% for both methods. Most of the few complications observed were due to sphincterotomy and subsided spontaneously or with medical treatment. However, one patient experienced a serous complication and chose to be treated by surgical intervention. The complication was caused by forceps biopsy. This study shows that 1) sampling of biliary strictures during ERCP is the primary approach to tissue diagnosis; 2) brush cytology alone is sufficient in clinical practice; 3) forceps biopsy must always be used to sample intra-ampullary strictures but should be considered as a secondary step to sample strictures located more proximally, in the bile ducta, if previous cytology was negative.

Full Text Available Background and Aim. Perforation after endoscopic retrograde cholangiopancreatography (ERCP is a rare complication, but it is associated with significant mortality. This study evaluated the early management experience of these perforations. Patients and Methods. Between November 2003 and December 2011, a total of 8504 ERCPs were performed at our regional endoscopy center. Sixteen perforations (0.45% were identified and retrospectively reviewed. Results. Nine of these 16 patients with perforations were periampullary, 3 duodenal, 1 gastric fundus, and 3 patients had a perforation of an afferent limb of a Billroth II anastomosis. All patients with perforations were recognized during ERCP by X-ray and managed immediately. One patient with duodenal perforation and three patients with afferent limb perforation received surgery, others received medical conservative treatment which included suturing lesion, endoscopic nasobiliary drainage (ENBD, endoscopic retrograde pancreatic duct drainage (ERPD, gastrointestinal decompression, fasting, broad-spectrum antibiotics, and so on. All patients with perforation recovered successfully. Conclusions. We found that: (1 the diagnosis of perforation during ERCP may be easy, but you must pay attention to it. (2 Most retroperitoneal perforations can recover with only medical conservative treatment in early phase. (3 Most peritoneal perforations need surgery unless you can close the lesion up under endoscopy in early phase.

The main treatment strategies for chronic pancreatitis in young patients include therapeutic endoscopic retrograde cholangio-pancreatography (ERCP) intervention and surgical intervention. Therapeutic ERCP intervention is performed much more extensively for its minimally invasive nature, but a part of patients are referred to surgery at last. Historical and follow-up data of 21 young patients with chronic pancreatitis undergoing duodenum-preserving total pancreatic head resection were analyzed to evaluate the outcomes of therapeutic ERCP intervention and surgical intervention in this study. The surgical complications of repeated therapeutic ERCP intervention and surgical intervention were 38% and 19% respectively. During the first therapeutic ERCP intervention to surgical intervention, 2 patients developed diabetes, 5 patients developed steatorrhea, and 5 patients developed pancreatic type B pain. During the follow-up of surgical intervention, 1 new case of diabetes occurred, 1 case of steatorrhea recovered, and 4 cases of pancreatic type B pain were completely relieved. In a part of young patients with chronic pancreatitis, surgical intervention was more effective than therapeutic ERCP intervention on delaying the progression of the disease and relieving the symptoms.

2003-01-01

Objective: To evaluate some specific CT and ERCP findings for differentiating the nature of biliary obstructive diseases. Methods: In total 85 cases of obstructive jaundice verified by pathology were selected. The CT findings in 45 cases and ERCP features in 68 cases were retrospectively analyzed. Results: Mild dilatation of intrahepatic bile ducts were usually found in benign diseases, while moderately or severely dilated intrahepatic bile ducts were revealed in malignancies. Dilatation of intrahepatic bile ducts in vine pattern was one of the characteristic signs of malignant lesions, while 'withered branches' dilatation was usually found in benign diseases. Dilated extra-hepatic bile duct abruptly narrowed or obstructed was a typical finding in malignancies, while gradual tapering of common bile duct at the obstructed level usually indicated benign nature of the disease. Conclusion: Both CT and ERCP are valuable modalities in locating and differential diagnosis of biliary obstruction. A combined evaluation improves the accuracy of diagnosis

 Endoscopic removal of asymptomatic common bile duct stones (CBDS) is generally recommended. Although many reports have described the risk of complications in endoscopic retrograde cholangiopancreatography (ERCP), no studies have addressed this problem in the context of asymptomatic CBDS. This study examines the risk of complications arising in ERCP for asymptomatic CBDS.  This retrospective study included 425 patients with naive papilla who underwent therapeutic ERCP for choledocholithiasis at 2 institutions in Japan for 2 years. The risk of complications was examined in patients who were divided into the asymptomatic and symptomatic CBDS groups. We used propensity score analysis to adjust for confounding effects.  Complications were observed in 32 (7.5 %) of the 425 patients. Of the 358 patients with symptomatic CBDS, 14 patients (3.9 %) had complications. In contrast, of the 67 patients with asymptomatic CBDS, 18 patients (26.9 %) had complications. Propensity score analysis revealed that asymptomatic CBDS was a significant risk factor, with a significantly higher incidence of complications compared with symptomatic CBDS (odds ratio, 5.3). Moderate to severe complications were observed in 15 of 18 patients (83.3 %) in the asymptomatic CBDS group, with significantly more moderate to severe complications than those in the symptomatic CBDS (odds ratio, 6.7).  Asymptomatic CBDS carried a high risk of ERCP-related complications, and these were often more severe. In asymptomatic CBDS, endoscopic treatment should be carefully performed after considering the patient's background, and detailed explanation of its possible complications should be given to patients in advance.

Preliminary research suggests that rectally administered nonsteroidal antiinflammatory drugs may reduce the incidence of pancreatitis after endoscopic retrograde cholangiopancreatography (ERCP). In this multicenter, randomized, placebo-controlled, double-blind clinical trial, we assigned patients at elevated risk for post-ERCP pancreatitis to receive a single dose of rectal indomethacin or placebo immediately after ERCP. Patients were determined to be at high risk on the basis of validated patient- and procedure-related risk factors. The primary outcome was post-ERCP pancreatitis, which was defined as new upper abdominal pain, an elevation in pancreatic enzymes to at least three times the upper limit of the normal range 24 hours after the procedure, and hospitalization for at least 2 nights. A total of 602 patients were enrolled and completed follow-up. The majority of patients (82%) had a clinical suspicion of sphincter of Oddi dysfunction. Post-ERCP pancreatitis developed in 27 of 295 patients (9.2%) in the indomethacin group and in 52 of 307 patients (16.9%) in the placebo group (P=0.005). Moderate-to-severe pancreatitis developed in 13 patients (4.4%) in the indomethacin group and in 27 patients (8.8%) in the placebo group (P=0.03). Among patients at high risk for post-ERCP pancreatitis, rectal indomethacin significantly reduced the incidence of the condition.

Wire-guided biliary cannulation has been demonstrated to improve cannulation rates and reduce post-ERCP pancreatitis (PEP), but the impact of wire caliber has not been studied. This study compares successful cannulation rates and ERCP adverse events by using a 0.025-inch and 0.035-inch guidewire. A randomized, single blinded, prospective, multicenter trial at 9 high-volume tertiary-care referral centers in the Asia-Pacific region was performed. Patients with an intact papilla and conventional anatomy who did not have malignancy in the head of the pancreas or ampulla and were undergoing ERCP were recruited. ERCP was performed by using a standardized cannulation algorithm, and patients were randomized to either a 0.025-inch or 0.035-inch guidewire. The primary outcomes of the study were successful wire-guided cannulation and the incidence of PEP. Overall successful cannulation and ERCP adverse events also were studied. A total of 710 patients were enrolled in the study. The primary wire-guided biliary cannulation rate was similar in 0.025-inch and 0.035-inch wire groups (80.7% vs 80.3%; P = .90). The rate of PEP between the 0.025-inch and the 0.035-inch wire groups did not differ significantly (7.8% vs 9.3%; P = .51). No differences were noted in secondary outcomes. Similar rates of successful cannulation and PEP were demonstrated in the use of 0.025-inch and 0.035-inch guidewires. (Clinical trial registration number: NCT01408264.). Copyright © 2018.

To describe the CT and ERCP findings of mass-forming chronic pancreatitis. CT and ERCP features were assessed in 13 patients suffering from mass-forming chronic pancreatitis. Diagnosis was on the basis of surgery (n=5), percutaneous needle biopsy (n=3), and clinical follow-up (n=5). Contrast-enhanced CT was available for all patients : five underwent dynamic study and ERCP was performed in 12. On CT and ERCP, both groups were evaluated with regard to the presence and degree of pancreatic ductal dilatation (greater or less than 50 % of total gland width), double duct sign, enhancement pattern, pancreatic parenchymal calcification (site and distribution pattern), mass identification, the direction of infiltration, pancreatic parenchymal atrophy, configuration at the site of obstruction in the pancreatic and common bile duct, lymphadenopathy, vascular encasement, and vascular engorgement or increased collateral vessels in the peripancreatic space. Seven of 13 patients had suffered chronic alcoholism. Serum CA19-9 levels were normal in all patients except one. Common CT and ERCP findings of mass-forming chronic pancreatitis included pancreatic duct dilatation (92.3%), double duct sign (69.2%), inhomogeneous enhancement of the mass (69.2%), and the presence of calcification (61.5%). Patterns of pancreatic duct dilation were irregular in five patients (38.4%) and smooth in three (23.1%). In all patients, duct dilatation was less than 50% of total gland width. Enhancement patterns of the pancreatic mass were inhomogeneous (69.2%), a nonenhancing low attenuation mass (15.3%), and homogeneous enhancement (15.3%). Configuration at the site of obstruction in the pancreatic duct was abrupt termination in two patients (15.4%) and smooth termination in two (15.4%). The common bile duct teminated abruptly in three patients (23.1%), and in four (30.8%) smooth narrowing was abserved.

Full Text Available We report a case in which a patient with intractable pain secondary to post-endoscopic retrograde cholangiopancreatography (ERCP acute pancreatitis is successfully treated with a subanesthetic ketamine infusion. Shortly after ERCP, the patient reported severe stabbing epigastric pain. She exhibited voluntary guarding and tenderness without distension. Amylase and lipase levels were elevated. Pain persisted for hours despite hydromorphone PCA, hydromorphone boluses, fentanyl boluses, and postprocedure anxiolytics. Pain management was consulted and a ketamine infusion was trialed, leading to a dramatic reduction in pain. This case suggests that ketamine may be a promising option in treating intractable pain associated with ERCP acute pancreatitis.

Full Text Available Background and aims: ERCP during pregnancy is always challenging for the entire team performing the endoscopic intervention. In this study techniques and different interventional aspects used at several centres about the clinical experience on ERCP in pregnant women are analyzed. Patients and methods: the practice on ERCP in pregnant women in six centers during a period of ten years is reported. Results: eleven patients were included in the study. Mean age was 30.6 years. Indication for ERCP was always symptomatic common bile duct stone (CBDS disease. Before the procedure abdominal ultrasound was performed at all times and magnetic resonance cholangiopancreatography in four occasions. Conscious sedation by means of midazolam and fentanyl or meperidine was applied. Sphincterotomes and guidewires were used for bilary cannulation. Sometimes, rapid exchange platforms with short-length guidewires controlled by the same endoscopist were employed. Biliary cannulation was confirmed in 9 occasions by bile aspiration. In five procedures, a mean of 30 seconds of fluoroscopy was used, both to verify cannulation and to corroborate complete CBDS clearance. These patients had the pelvic zone protected with a lead shield and radiation dose was measured. Ten biliary sphincterotomies were performed followed by CBDS extraction. Two plastic stents were inserted. Relief of biliary obstruction was attained in all circumstances. Only one patient had hyperamylasemia after ERCP. All pregnant women had healthy foetuses with normal deliveries. Conclusions: with experience, ERCP appears to be a safe technique during pregnancy. With simple measures fluoroscopic time can be diminished or even abolished. It seems that ERCP during pregnancy is underused in our working areas, although it has shown to be a useful technique for relieving biliary obstruction.Antecedentes y objetivos: la CPRE realizada durante el embarazo constituye siempre un reto para todo el equipo que participa

The Anesthetic Effect of Dexmedetomidine on ERCP of Senile Patients

2017-01-01

Full Text Available Objective: to discuss the effectiveness and security of Dexmedetomidine’s conscious-sedation application in ERCP of senile patients. Method: selecting 80 senile patients performed with ERCP and randomly dividing them into Dexmedetomidine group (group D and normal saline group (group C with 40 cases in each group. Pumping 0.5 ~ 0.8 ug/kg Dexmedetomidine through the vein 15 min after surgery while pumping isodose NS to group C at the same time. Results: both the two groups completed the ERCP treatment. The tolerance of group C is poorer with more adverse reactions; the operating time of group D is shorter, but the difference has no statistical significance. During the operation, compared with group D, the MBP and HR value of group C rose obviously with significant difference (P < 0.05 while the MBP has no obvious change within the group; HR declined sharply after pump injection (P < 0.05, but the value is within the normal range. The contrast of SPO2 and RR within and between the two groups have no significant difference. Conclusion: applying Dexmedetomidine for conscioussedation in senile patients’ ERCP leads to hemodynamic stability and no respiratory depression with less adverse reactions. The application during the perioperative period is effective, safe and comfortable, worthy of popularization and application in clinic.

A recent large-scale randomized controlled trial (RCT) demonstrated that rectal indomethacin administration is effective in addition to pancreatic stent placement (PSP) for preventing post-endoscopic retrograde cholangiopancreatography (ERCP) pancreatitis (PEP) in high-risk cases. We performed a post hoc analysis of this RCT to explore whether rectal indomethacin can replace PSP in the prevention of PEP and to estimate the potential cost savings of such an approach. We retrospectively classified RCT subjects into four prevention groups: (1) no prophylaxis, (2) PSP alone, (3) rectal indomethacin alone, and (4) the combination of PSP and indomethacin. Multivariable logistic regression was used to adjust for imbalances in the prevalence of risk factors for PEP between the groups. Based on these adjusted PEP rates, we conducted an economic analysis comparing the costs associated with PEP prevention strategies employing rectal indomethacin alone, PSP alone, or the combination of both. After adjusting for risk using two different logistic regression models, rectal indomethacin alone appeared to be more effective for preventing PEP than no prophylaxis, PSP alone, and the combination of indomethacin and PSP. Economic analysis revealed that indomethacin alone was a cost-saving strategy in 96% of Monte Carlo trials. A prevention strategy employing rectal indomethacin alone could save approximately $150 million annually in the United States compared with a strategy of PSP alone, and $85 million compared with a strategy of indomethacin and PSP. This hypothesis-generating study suggests that prophylactic rectal indomethacin could replace PSP in patients undergoing high-risk ERCP, potentially improving clinical outcomes and reducing healthcare costs. A RCT comparing rectal indomethacin alone vs. indomethacin plus PSP is needed.

Acute pancreatitis is the most common adverse event of endoscopic retrograde cholangiopancreatography (ERCP). Recent data suggest that indomethacin can reduce the risk of post-ERCP pancreatitis (PEP) in high-risk individuals. However, whether the combination of indomethacin and sublingual nitrates is superior to indomethacin alone is unknown. Therefore, we aimed to evaluate the efficacy of rectally administered indomethacin plus sublingual nitrate compared with indomethacin alone to prevent PEP. During a 17-month period, all eligible patients who underwent ERCP were enrolled in this study. We excluded patients who had undergone a prior endoscopic sphincterotomy. In a double-blind controlled randomized trial, patients received a suppository containing 100 mg of indomethacin, plus 5 mg of sublingual nitrate (group A), or a suppository containing 100 mg of indomethacin, plus sublingual placebo (group B), before ERCP. Serum amylase levels and clinically pertinent evaluations were measured in all patients after ERCP. Of the 300 enrolled patients, 150 received indomethacin plus nitrate. Thirty-three patients developed pancreatitis: 10 (6.7%) in group A and 23 (15.3%) in group B (P=0.016, risk ratio=0.39, 95% confidence intervals (CI): 0.18-0.86). More than 80% of the patients were at high risk of developing pancreatitis after ERCP. Absolute risk reduction, relative risk reduction, and number needed to treat for the prevention of PEP were 8.6% (95% CI: 4.7-14.5), 56.2% (95% CI: 50.6-60.8), and 12 (95% CI: 7-22), respectively. Combination of rectal indomethacin and sublingual nitrate given before ERCP was significantly more likely to reduce the incidence of PEP than indomethacin suppository alone. Multicenter trials to confirm these promising findings are needed.

Full Text Available Device assisted enteroscopy (DAE techniques have been recently developed for the diagnosis and treatment of small bowel diseases. These techniques can also be used to perform endoscopic retrograde cholangiopancreatography (ERCP in patients with surgically altered anatomies. The main difficulties with DAE-ERCP are related to type of surgery, to the different dimensions and lack of frontal view of the enteroscope and to the resulting limitations with the use of standard accessories, resulting in the need of dedicated accessory devices. Although most ERCP techniques have been successfully performed with DAE-ERCP, biliary self-expandable metallic stents (SEMS have not yet been used, as dedicated biliary SEMS for the enteroscope are lacking. The authors present a case report showing a new method to place standard biliary trough-the-scope SEMS with DAE-ERCP, using a different technique of stent deployment.

Full Text Available Aim To define a therapeutic program for mild-moderate acute pancreatitis (AP, often recurrent, which at the end of the diagnostic process remains of undefined etiology. Material and Methods In the period 2011-2012, we observed 64 cases of AP: 52 mild-moderate, 12 severe; biliary 39, biliary in alcoholic chronic pancreatitis 5, unexplained recurrent 20. The clinical and instrumental evaluation of the 20 cases of unexplained AP showed 6 patients with biliary sludge, 4 microlithiasis, 4 sphincter of Oddi dysfunction, and 6 cases that remained undefined. Results Among 20 patients with recurrent, unexplained AP at initial etiological assessment, we performed 10 video laparo cholecystectomies (VLCs, 2 open cholecystectomies and 4 endoscopic retrograde cholangiopancreatography/endoscopic sphincterotomies (ERCP/ES in patients who had undergone previous cholecystectomy; 4 patients refused surgery. Among these 20 patients, 6 had AP that remained unexplained after second-level imaging investigations. For these patients, 4 VLCs and 2 ERCP/ES were performed. Follow-up after six months was negative for further recurrence. Conclusion The recurrence of unexplained acute pancreatitis could be treated with empirical cholecystectomy and/or ERCP/ES in cases of previous cholecystectomy.

ERCP-the role of radiologist or what the endoscopist needs to know

Manova, G.; Totev, M.

2012-01-01

Endoscopic retrograde cholangiopancreatography (ERCP) is an interdisciplinary endoscopic-radiologic method for diagnosis and treatment of the diseases of the biliary and pancreatic ducts. The procedure requires an excellent technical experience and high professional qualification of the medical team. The cannulation of the papilla of Vater and the contrast imaging of the hepatobiliary tree and the pancreatic duct need co-operation between the radiologist and endoscopist for interpretation of the findings - malignant or benign stenosis, choledocholithiasis, iatrogenic lesions. The undertaken endoscopic therapeutic procedures are performed under fluoroscopic guidance as well as the subsequent assessment of their effective - stone extraction, stent placement, etc. The good collaboration of the team during each stage of the procedure can guarantee its success.

There are only a few cases found in literature regarding air embolism in endoscopic procedures, especially in connection to endoscopic retrograde cholangiopancreatography (ERCP). We are presenting a case of a 56-year-old female patient who suffered from non-Hodgkin lymphoma located in her right groin. She was also diagnosed with choledocholithiasis and underwent ERCP to remove the gallstones. Immediately after the procedure she went into sudden cardiac arrest and subsequently died, despite all of our efforts. We reviewed literature in order to identify possible causes of death because fatal outcome following an uneventful and successful procedure was not expected. It is important to bear in mind all possible complications of ERCP. Our focus during the literature search was on air embolism.

Cannulation of the papilla of Vater was successful in 49 out of 65 cases (75.4%) and digital imaging of the pancreas in 38% of cases. Visualisation of the pancreatic duct with D-ERP was comparable to that of conventional ERCP. Absent or faint opacification of the parenchyma was seen in 39.5% of patients. Both methods were equally effective for the diagnosis of pancreatic tumours. D-ERP was better than ERCP for the diagnosis of chronic pancreatitis. Two patients (4.1%) had clinical evidence of mild acute pancreatitis following pancreatic duct injections. (orig.) [de

Full Text Available A 45-year-old woman with suspected Functional Biliary Sphincter Disorder (FBSD developed Clostridium perfringens related emphysematous cholecystitis after ERCP. A low index of suspicion for emphysematous cholecystitis in this young, otherwise healthy woman led to a significant delay in making the correct diagnosis, and air in the gallbladder was wrongly attributed to a possible gallbladder perforation. ERCP is associated with significant risks, particularly in patients with FBSD, where diagnostic uncertainty renders the balance of risk versus benefit even more critical. Post-ERCP emphysematous cholecystitis secondary to Clostridium perfringens is a rare but potentially fatal complication.

Biliary complications (BC) occur in up to 39.5% of patients after orthotopic liver transplantation (OLT), being an important source of post-transplant morbidity. The aim is to evaluate the incidence of BC after OLT, associated risk factors and outcome after endoscopic treatment. A retrospective case series between June 2005 and December 2008, including 195 patients that underwent 216 OLT from deceased donors. Thirty-one patients (14.3%) presented at least 1 BC, anastomotic stricture being the most frequent (83.8%). Non-anastomotic stricture was present in 1 (3.2%) and anastomotic fistula in 1. One patient presented anastomotic disconnection at ERCP. BC occurred 94.6 (7-487) days after OLT. Twenty-seven patients underwent endoscopic treatment, on average 2.6 ERCPs were performed per patient. Global endoscopic treatment success rate was 77.3%; being 73.7% for stenosis and 100% (3/3) for anastomotic fistula with stenosis. Recurrence of biliary stricture was observed in 3 patients, all referred to endoscopic re-treatment. ERCP complications: 2 (2.8%) stent migrations, 1 (1.4%) early stent occlusion, 1 (1.4%) respiratory distress and 1(1.4%) severe acute pancreatitis and death. There was no correlation between studied risk factors and BC's occurrence. ERCP was effective for the treatment of BC after OLT. Studied risk factors had no correlation with BC.

Acute pancreatitis is a common diagnosis worldwide, with gallstone disease being the most prevalent cause (50%). The American College of Gastroenterology recommends urgent endoscopic retrograde cholangiopancreatography (ERCP) (within 24 h) for patients with biliary pancreatitis accompanied by cholangitis. Most international guidelines recommend that ERCP be performed within 72 h in patients with biliary pancreatitis and a bile duct obstruction without cholangitis, but the optimal timing for endoscopy is controversial. We investigated the optimal timing for ERCP in patients with biliary pancreatitis and a bile duct obstruction without cholangitis, and whether performing endoscopy within 24 h is superior to performing it after 24 h. We analyzed the clinical data of 505 patients with newly diagnosed acute pancreatitis, from January 1, 2005 to December 31, 2014. We divided the patients into two groups according to the timing of ERCP: pancreatitis and a bile duct obstruction without cholangitis. The mean age of the patients was 55 years (range: 26-90 years). Bile duct stones and biliary sludge were identified on endoscopy in 45 (61.6%) and 11 (15.0%) patients, respectively. The timing of ERCP within 72 h was not associated with ERCP-related complications (P = 0.113), and the total length of hospital stay was not different between urgent and early ERCP (5.9 vs. 5.7 days, P = 0.174). No significant differences were found in total length of hospitalization or procedural-related complications, in patients with biliary pancreatitis and a bile duct obstruction without cholangitis, according to the timing of ERCP (< 24 h vs. 24-72 h).

OBJECTIVE: Acute pancreatitis is the most dreaded complication of ERCP. Two studies have shown a significant effect of glyceryl nitrate (GN) in preventing post-ERCP pancreatitis (PEP). We wanted to evaluate this promising effect in a larger study with a realistically precalculated incidence of PEP...... (PL) was an identical-looking patch applied before ERCP. A total of 401 patients received GN; 405 received PL. RESULTS: Forty-seven patients had PEP (5.8%), 18 (4.5%) in the GN group and 29 (7.1%) in the PL group. The relative risk reduction of PEP in the GN group of 36% (95% CI, 11%-65%) compared...... (P = .006) were more common in the GN group. Significant variables predictive of PEP were not having biliary stones extracted; hypotension after ERCP; morphine, propofol, glucagon, and general anesthesia during the procedure; or no sufentanil during the procedure. CONCLUSIONS: The trial showed...

The role of early endoscopic retrograde cholangiopancreatography (ERCP) and sphincterotomy in acute pancreatitis is controversial. Recent randomised controlled trials mostly support the value of this procedure, but concerns remain as to its safety, efficacy and practicability. This debate critically assesses the evidence for and against the use of early ERCP in acute pancreatitis.

There is no consensus regarding the appropriate use of endoscopic retrograde cholangiopancreatography (ERCP) in pediatric trauma. We report our experience with ERCP for management of pediatric pancreatic and biliary injury following blunt abdominal trauma. A retrospective chart review was performed for pediatric patients with blunt abdominal trauma from July 2008 through December 2012 at our pediatric trauma center. For patients who underwent ERCP, demographics, injury characteristics, diagnostic details, procedures performed, length of stay, total parenteral nutrition use, and complications were reviewed. There were 532 patients identified: 115 hepatic injuries, 25 pancreatic injuries and one gall bladder injury. Nine patients (mean age 7.8 years) underwent ERCP. Seven (78%) had pancreatic injuries, while two (22%) had bilateral hepatic duct injuries. The median time to diagnosis was one day (range, 0-12). Diagnostic ERCP only was performed in three patients, two of which proceeded to distal pancreatectomy. Five patients had stents placed (two biliary and three pancreatic) and four sphincterotomies were performed. Despite pancreatic stenting, one patient required distal pancreatectomy for persistent leak. Median length of stay was 11 days. Pediatric pancreatic and biliary ductal injuries following blunt abdominal trauma are uncommon. ERCP can safely provide definitive treatment for some patients. Copyright © 2015 Elsevier Inc.

Full Text Available Abstract Background Endoscopic retrograde cholangiopancreatography (ERCP is widely performed as a treatment for biliary and pancreatic illness in China; however, there are few data available regarding post-ERCP infections. This study aimed to describe the overall incidence of post-ERCP infections and the epidemiological characteristics of infected patients in a large tertiary-care hospital in China. Methods Real-time surveillance was performed from 2012 through 2015 to identify all healthcare-associated infections (HAIs that occurred after ERCP, using an automatic system. All HAIs (e.g., cholangtitis, bacteremia were identified by infection control practitioners and doctors. Inpatient data were automatically collected by the surveillance system. Results A total of 1743 ERCP operations were included in the study, among these, 132 (7.57% HAIs were identified. ERCP postoperative infections occurred following different surgical procedures, with infection rates ranging from 3.58 to 13.51%. The most prevalent HAI was biliary tract infection (4.02%, followed by transient bacteremia (1.14%. Overall, 62 cases of bacteremia occurred following ERCP surgery and 34 (54.84% cases occurred on the day of the operation or 1-day post-surgery. The most prevalent isolates detected during bacteremia were Enterococcus faecium (12/58 and Escherichia coli (11/58. A large proportion (72.73% of the E. coli isolates and all of the E. faecium isolates were resistant to ciprofloxacin. In addition, only 37.50% of the E. coli isolates were susceptible to ceftriaxone. Conclusions The high incidence of post-ERCP infection and the prevalence of drug resistance suggests that employing second generation cephalosporin or ceftriaxone as the antibiotic of choice for prophylaxis before ERCP, as recommended by the Chinese clinical application of antibacterial drugs guidelines, may not be effective.

Acute pancreatitis is one of the most common complications of endoscopic retrograde cholangiopancreatography (ERCP). Numerous studies have shown that administered nonsteroidal anti-inflammatory drugs (NSAIDs) may reduce the incidence of acute pancreatitis after ERCP. Little is known, however, about the mechanism of NSAIDs in preventing pancreatitis (PEP). In this study, we assigned patients to receive a single dose of intramuscular diclofenac 75 mg immediately after ERCP (diclofenac group) or without (control group). The primary outcome measure was the occurrence of PEP. The serum amylase levels were measured before ERCP and at 3 and 24 h post-procedure in all patients. The Lipoxin A4 (LXA4), Resolvin D1 (Rvd1), and Resolvin E1 (RvE1) levels were measured before ERCP, and 3 and 24 h after the procedure in 30 patients from the diclofenac group and 30 patients from the control group. A total of 120 patients were enrolled and completed the follow-up. The overall incidence of PEP was 13.3% (16/120). It occurred in four of 60 patients (6.67%) in the diclofenac group and in 12 of 60 patients (20.00%) in the control group (p = 0.032). The LxA4, RvD1, and RvE1 levels in the diclofenac group at 3 h after ERCP were significantly increased compared with before ERCP (p diclofenac group at 3 and 24 h after ERCP were significantly increased (p diclofenac after ERCP can reduce the incidence of PEP. This may be related to the fact that diclofenac can increase the levels of LxA4, RvD1, and RvE1.

Selective biliary cannulation is unsuccessful in 5 % to 10 % of patients undergoing endoscopic retrograde cholangiopancreatography (ERCP) for malignant distal biliary obstruction (MDBO). Percutaneous biliary drainage (PBD) has been the gold standard, but endoscopic ultrasound guided rendezvous (EUSr) have been increasingly used for biliary decompression in this patient population. Our aim was to compare the initial success rate, long-term efficacy, and safety of PBD and EUSr in relieving MDBO after failed ERC Patients and methods: A retrospective study involving 50 consecutive patients who had an initial failed ERCP for MDBO. Twenty-five patients undergoing EUSr between 2008 - 2014 were compared to 25 patients who underwent PBD immediately prior to the introduction of EUSr at our center (2002 - 2008). Comparisons were made between the two groups with regard to technical success, duration of hospital stay and adverse event rates after biliary decompression. The mean age at presentation was 66.5 (± 12.6 years), 28 patients (54.9 %) were female. The etiology of MDBO was pancreaticobiliary malignancy in 44 (88 %) and metastatic disease in 6 (12 %) cases. Biliary drainage was technically successful by EUSr in 19 (76 %) cases and by PBD in 25 (100 %) (P = 0.002). Median length of hospital stay after initial drainage was 1 day in the EUSr group vs 5 days in PBD group (P = 0.02). Repeat biliary intervention was required for 4 patients in the EUSr group and 15 in the PBD group (P = 0.001). Initial technical success with EUSr was significantly lower than with PBD, however when EUSr was successful, patients had a significantly shorter post-procedure hospital stay and required fewer follow-up biliary interventions.

To assess the correlation between magnetic resonance cholangiopancreatography (MRCP) and endoscopic retrograde cholangiopancreatography (ERCP). The authors carried out a prospective study of 71 patients suspected of having biliary diseases. MRCP was performed, followed by ERCP.MRCP was done with a 1.5-T system using hypergradients, abdominal phase array coil and single-shot fast spin-echo (SSFSE) sequences with maximum signal intensity in T2-weighted images. This sequence only provides images of the fluids, similar to those obtained with ERCP. The results of ERCP were employed as a reference standard. Thirty patients were found to have stenosis (19 malignant and 11 benign). 25 had choledocholithiasis and 16 showed no abnormal findings. The correlation was complete in patients with stenosis. MRCP detected 23 cases of choledocholithiasis (ERCP was normal in the remaining two patients, but calculi were discovered on shpincterotomy). MRCP confirmed the normal condition of the bile duct in 12 of the 16 patients free of biliary disease (2 patients in whom ERCP had been normal had been diagnosed as having bile duct dilatation due to choledocholithiasis 24 hours and 10 days earlier, respectively, and two cases of presented ectasia due to fibrosis of the sphincter of Oddi showed good emptying during ERCP). MRCP using SSFSE is highly correlated with ERCP, which should be reserved for cases in which the diagnosis is in doubt or endoscopic management is necessary. (Author) 25 refs.

To differentiate the pancreatic adenocarcinoma from focal pancreatitis on CT and ERCP in cases of focal pancreatic enlargement. We analysed CT findings of 66 patients of pancreatic adenocarcinoma (n = 45) or focal pancreatitis (n = 21) with respect to size, density, calcification, pancreatic or biliary duct dilatation, fat plane obliteration around the vessels, direction of retroperitoneal extension, lymphadenopathy, pseudocyst formation and atrophy of pancreas. ERCP available in 48 patients were analysed in respect to morphologic appearance of CBD and pancreatic duct, and distance between the two ducts. The patients in focal pancreatitis were younger with more common history of alcohol drinking. There was no statistical difference in calcifications of the mass (18% in the adenocarcinoma, 33% in the focal pancreatitis), but a tendency of denser, larger number of calcifications was noted in focal pancreatitis. The finding of fat plane obliteration around the vessels were more common in pancreatic adenocarcinoma, and fascial thickenings were more prominent in focal pancreatitis, although not statistically significant. On ERCP, there were no differential points of CBD, pancreatic duct morphology, but distance between the two ducts at the lesion center was more wider in focal pancreatitis. Differentiating focal pancreatitis from pancreatic adenocarcinoma is difficult. However, we should consider the possibility of focal pancreatitis in cases of patients with young age, having alcoholic history in association with CT findings of large numbers of and dense calcifications, and ERCP findings of prominent separation of two duct at the lesion center

The cause of pancreatitis is unknown in as many as 30% of cases of recurrent acute pancreatitis, even after ERCP. To investigate the role of intraductal US (IDUS) for managing idiopathic recurrent pancreatitis (IRP). Prospective study. Tertiary referral hospital. Thirty-one patients with suspicious IRP with negative findings on ERCP. IDUS during ERCP. IDUS findings showing any possible cause of pancreatitis. IDUS revealed small bile duct stones (≤3 mm) in 5 patients (16.1%) and sludge in 3 patients (9.7%). The detection rate for a bile duct stone and sludge was significantly higher in patients with a dilated CBD than a nondilated CBD on ERCP (71.4 vs 12.5%; P < .05). Recurrent pancreatitis did not develop in 7 of 8 patients with biliary stones or sludge after an endoscopic sphincterotomy (EST). Two patients (6.5%) demonstrated a small polypoid lesion on the distal end of the pancreatic duct. One patient underwent surgery for intra-ampullary cancer, and another one underwent EST without another attack of pancreatitis. Three patients (9.7%) showed evidence of chronic pancreatitis with small pancreatic stones and/or calcifications on IDUS. Small number of patients. IDUS results were not compared with those of conventional EUS. There was no reference standard for chronic pancreatitis as diagnosed by IDUS. IDUS identified a possible cause of idiopathic recurrent pancreatitis in 42% of patients with negative findings on ERCP. The IDUS-guided approach combined with ERCP and EST may be useful for decreasing recurring attacks of pancreatitis. Copyright © 2011 American Society for Gastrointestinal Endoscopy.

A prospective study of the diagnostic yield of ultrasound (US) and ERCP was made on a continuous series of 424 patients. Technical failures were slightly more frequent with US (11%) than with ERCP (8%), while US proved more accurate than ERCP in the diagnosis of focal hepatic disease -94% of correct diagnoses versus 41% (n=17). In diffuse hepatic disease (n=63) the accuracy of both methods was the same -87% of correct diagnoses with US, 83% with ERCP. US had better performances (91%), while ERCP was more accurate in the diagnosis of common duct lithiasis or tumor (98% for ERCP, 36% for US). Although ERCP has a better diagnostic yield for pancreatic diseases (92% to 100% of correct diagnoses according to the lesions) associate complications, such as pseudo-cysts, abscess formation and extravasations are better demonstrated by US (95% of correct diagnoses versus 73%). The two methods thus prove to be complementary. (orig.)

Full Text Available Backgrounds and aim: endoscopic retrograde cholangiopancreatography (ERCP is an established procedure to drain the biliary and pancreatic ducts. Nevertheless, there are complications which seem to be more common in centers performing less than 200 ERCPs per year. Sometimes, however, due to the distribution of health resources, it is necessary to perform this technique in centers with a smaller number of procedures. We present the experience of ERCP-related complications in a small unit. Material and methods: this is a retrospective study on prospective data recorded during six years (1997-2002. In this period, two endoscopists working together performed 507 ERCPs, which yields an approximately average of 84 procedures per year. Results: in 507 ERCPs performed during this period of time, 55 complications arose (10.85%, and four patients died (0.79% as a consequence of the procedure. There were 28 pancreatitis (5.5%, eight post-sphincterotomy bleeding events (1.6%, seven bilioduodenal perforations (1.4%, eight sepsis episodes of biliary origin (1.6%, and other 4 different complications. There were 418 (82.4% successful ERCPs -either diagnostic or therapeutic-, which gave rise to 46 (11% complications. There were 89 (17.6% failed diagnostic or therapeutic ERCPs, which gave rise to 9 (10.11% complications (p = 0.8 between both groups. Thirty five (7% ERCPs were exclusively diagnostic and caused 6 (17% complications. The 187 procedures performed for coledocho-lithiasis originated 14 (7.4% complications, and represented the group with the lowest morbidity rate (p = 0.04. Conclusions: the complications rate in our center is within the range of reported figures. ERCPs performed for choledoco-lithiasis was associated with the lowest complications rate. The risk-benefit ratio in the anticipated, purely diagnostic ERCP must be carefully weighed due to its morbidity.Antecedentes y objetivo: la colangiopancreatografía retrógrada endoscópica (CPRE es un

Acute pancreatitis is one of the common reasons for surgical admission. It is a potentially lethal disease that is increasing in its incidence. The most common causes of acute pancreatitis is from gallstones and alcohol. Other causes of acute pancreatitis include hypertriglyceridaemia, hyperparathyroidism, pancreatic malignancy, Endoscopic retrograde cholangiopancreatography (ERCP), trauma, infectious agents, drugs, autoimmunity, and hereditary. The treatment of acute pancreatitis is mainly supportive. The complication of ERCP in acute pancreatitis can be divided into local complication (pancreatic abscess, pseudocyst), systemic complications (renal failure, respiratory failure, cardiogenic shock) and biliary sepsis (acute cholangitis and acute cholecystitis). However, early ERCP and possible sphincterotomy should be kept in mind for patients with severe disease and biliary obstruction who are not improving with medical therapy. This study is done to compare the complication rate of ERCP and conservative management in acute pancreatitis for past 6 years in Pusat Perubatan UKM. The study is conducted retrospectively and the study population was from January 2003 until December 2008. About 100 patients involving 51 males and 49 females were included in this study. All of them were diagnosed acute pancreatitis based on the serum amylase level of 4 times than normal value detected from Chemistry Pathology record, Pathology Department, PPUKM. Then, data were collected from the patient's file which include the demographic data and patient clinical presentation, ultrasound finding, either patient went for ERCP within 72 hours or not. If ERCP not done within 72 hours of admission then it will considered that the patient is under conservative management. From 100 patients that involved in this study about 44% was Malay, 36 % was Chinese, 18 % was Indian and the other 2 % was from other origin. There were 28 cases (28%) where ERCP was done within 72 hours, and the other 72

The ideal treatment algorithm for suspected choledocholithiasis is not yet well defined. Imaging options include magnetic resonance cholangiopancreatography (MRCP), endoscopic retrograde cholangiopancreatography (ERCP), and intraoperative cholangiogram (IOC). MRCP is diagnostic, while the other two modalities can also be therapeutic. Each of these modalities for diagnosis and treatment carries its own set of risks, benefits, and institutional costs. We hypothesized that there would be a significant difference between the biochemical profiles and characteristics of patients who undergo ERCP vs. MRCP vs. operative intervention as the initial choice of treatment/imaging modality. We performed a retrospective review of the electronic medical records for all patients with a coded diagnosis of choledocholithiasis from 2011 to 2014. The initial diagnostic modality was assessed for each hospital encounter. The statistical characteristics of MRCP as compared to fluoroscopic imaging of the biliary tree (ERCP, IOC) were analyzed. Overall, 527 hospital encounters were identified. Initial intervention included ERCP in 63%, MRCP in 12%, and cholecystectomy in 25% of patients. Patients undergoing cholecystectomy first, compared to MRCP or ERCP, tended to have lower values for alkaline phosphatase (P utility in this patient population should be questioned. Further research is needed to better define the pretest characteristics which would predict which patients do not need further intervention after MRCP as well as defining the most cost-effective strategy.

The clinical usefulness of MR cholangio-pancreatography (MRCP) by fast spin echo method was compared with that of endoscopic retrograde cholangio pancreatography (ERCP). In MRCP, favorable images of bile and pancreatic ducts were obtained in 66.7% (78/117) and bile duct images in 16.2% (19/117), showing the overall efficacy rate of 92.9% (97/117). Seventy-seven of these images were compared with simultaneously obtained favorable ERCP images. The excellent and favorable rate of MRCP reached 84.5% (65/77), showing clinical usefulness of MRCP. Obscure images were considered due to insufficient breath-hold time. (S.Y.)

Full Text Available BACKGROUND: Acute pancreatitis is the most common complication of diagnostic and therapeutic endoscopic retrograde cholangiopancreatography (ERCP. Several clinical trials used glyceryl trinitrate (GTN to prevent the incidence of post-ERCP pancreatitis (PEP. However, the results were still controversial. OBJECTIVE: To conduct a meta-analysis of published, full-length, randomized controlled trials evaluating the effect of prophylactic GTN on the prevention of PEP, improve the rate of cannulation and the prevention of hyperamylasemia. METHODS: Literature searches were conducted using PubMed, EMBASE, The Cochrane Library and Web of Knowledge databases, using keywords "post-ERCP" and "pancreatitis" and limited in randomized controlled trials. RESULTS: Twelve RCTs involving 2649 patients were included. Eleven RCTs compared GTN with placebo for PEP prevention. Meta-analysis showed the overall incidence of PEP was significantly reduced by GTN treatment (RR 0.67; 95% CI, 0.52-0.87. Nevertheless, GTN administration did not decrease the incidence of moderate to severe PEP (RR 0.70; 95% CI, 0.42-1.15. Subgroup analyses revealed that GTN administered by sublingual was more effective than transdermal and topical in reducing the incidence of PEP. Besides, the prophylactic effect of GTN was far more obvious in the group of high PEP incidence than in the group of low PEP incidence. Additionally, the incidence of hyperamylasemia was significantly reduced by GTN treatment (RR 0.69; 95% CI, 0.54-0.90. No differences of the successful cannulation rate of bile ducts (RR 1.03; 95% CI, 0.99-1.06 attributable to GTN were observed. CONCLUSION: Prophylactic use of GTN reduced the overall incidence of PEP and hyperamylasemia. However, GTN was not helpful for the severity of PEP and the rate of cannulation.

To evaluate the major radiologic features of chronic focal pancreatitis in various imaging studies, with special emphasis on CT and ERCP findings. From 1991 to 1995, twelve patients were pathologically proved to be suffering from focal chronic pancreatitis after pancreatico-duodenectomy;for retrospective evaluation, imaging studies were available for eight(seven men, one woman;mean age 58.9{+-}6.6, range 47 to 67). Clinical, surgical, and radiological findings, including CT(n=8), ultrasound(n=7), ERCP(n=8) and UGI(n=3) were analysed. Seven male patients had suffered from chronic alcoholism for between 20 and 50 years. Serum bilirubin levels were normal in eight patients and alkaline phosphatase levels were normal in seven patients. Serum CA 19-9 levels were normal in all five patients who had undergone preoperative evaluation. Seven patients(87.5%) showed focal enlargement without definable margin on CT, and five of the six lesions detectable on ultrasound(83.3%) were ill defined hypoechoic nodules. Dilated side branches within lesions were seen in five of eight patients(83.3%) on CT and ERCP. Double duct signs were observed in siven(87.5%) patients, and dilated intrahepatic ducts in six(75%), with diameters ranging from 5 to 8mm(average:5.42{+-}1.96mm). The average ratio of pancreatic duct caliber to gland width was 0.33{+-}0.19. None of the patients had calcification within the lesion and one case showed intraductal calcification. None showed perivascular fat obliteration around the superior mesenteric artery or celiac axis. The average biductal distance between abnormal common bile duct and the immediately adjacent pancreatic duct was 4.0{+-}1.15mm.

Full Text Available ObjectiveTo investigate the clinical effect of endoscopic nasobiliary drainage (ENBD in the prevention of post-endoscopic retrograde cholangiopancreatography (ERCP pancreatitis (PEP and hyperamylasemia in patients with choledocholithiasis. MethodsA total of 560 patients with choledocholithiasis who underwent ERCP from October 2010 to December 2013 were included in the study. ENBD was performed in 371 patients (test group, and the other 189 patients were designated as control group. Serum amylase level was measured at 3 and 24 h after ERCP, and the incidence of PEP and hyperamylasemia was determined. Comparison of continuous data between the two groups was made by t test, while comparison of rates was made by chi-square test. ResultsThe incidence rates of PEP and hyperamylasemia in the test group were 8.1% (30/371 and 13.7% (51/371, respectively, significantly lower than those in the control group (13.8%, 26/189; 21.2%, 40/189, (χ2 = 4.47, P=0.034; χ2=5.06, P=0.024. The serum amylase levels at 3 and 24 h after ERCP in the test group were 215.34±304.00 U/L and 199.38±273.32 U/L, respectively, significantly lower those in the control group (283.28±261.76 U/L and 257.05±199.25 U/L (t=2.61, P=0.01; t=2.57, P=0.01. ConclusionENBD can effectively reduce the incidence of PEP and hyperamylasemia in patients with choledocholithiasis.

The 'Rendezvous' technique consists of laparoscopic cholecystectomy (LC) standards with intra-operative cholangiography followed by endoscopic sphincterotomy. The sphincterotome is driven across the papilla through a guidewire inserted by the transcystic route. In this study, we intended to compare the two methods in a prospective randomised trial. From 2005 to 2012, we enrolled 83 patients with a diagnosis of cholecysto-choledocolithiasis. They were randomised into two groups. In 'group-A',41 patients were treated with two stages management, first by pre-operative endoscopic retrograde cholangiopancreatography (ERCP) and common bile duct (CBD) clearance and second by LC. In 'group-B', 42 patients were treated with LC and intra-operative cholangiography; and when diagnosis of choledocholithiasis was confirmed, patients had undergone one stage management of by Laparo-endoscopic Rendezvous technique. In arm-A and arm-B groups, complete CBD clearance was achieved in 29 and 38 patients, respectively. Failure of the treatment in arm-A was 29% and in arm-B was 9.5%. In arm-A, selective CBD cannulation was achieved in 33 cases (80.5%) and in arm-B in 39 cases (93%). In arm-Agroup, post-ERCP hyperamylasia was presented in nine patients (22%) and severe pancreatitis in five patients (12%) versus none of the patients (0%) in arm-B group, respectively. Mean post-operative hospital stay in arm-A and arm-B groups are 10.9 and 6.8 days, respectively. One stage laparo-endoscopic rendezvous approach increases selective cannulation of CBD, reduces post-ERCP pancreatitis, reduces days of hospital stay, increases patient's compliance and prevents unnecessary intervention to CBD.

Risk Evaluation of Endoscopic Retrograde Cholangiopancreatography-Related Contrast Media Allergic-Like Reaction: A Single Centre Experience

Full Text Available Background and Aims. Few cases of endoscopic retrograde cholangiopancreatography- (ERCP- related contrast media (CM adverse reactions have been reported in the current literature. There is a lack of standardisation in practice regarding premedication prophylaxis for at-risk patients undergoing ERCP and there are few data to guide the practitioners. Our goal is to evaluate the risk of CM adverse reaction in a group of patients with a past history of allergic-like reaction to iodine product undergoing ERCP. Methods. A retrospective chart review study was performed of patients who underwent ERCP at our single centre from January 2010 to December 2015. Results. 2295 ERCPs were performed among 1766 patients. No anaphylactoid or severe adverse reaction occurred. One (0.04% ERCP-related CM benign reaction was reported in a patient known for penicillin allergy. Among 127 ERCPs performed on patients with a prior adverse reaction to iodine, 121 procedures were done without and 6 with a premedication prophylaxis. In both groups, no ERCP-related CM reaction occurred. Conclusions. To our knowledge, we report the largest cohort of iodine allergic patients undergoing ERCP ever published. These results suggest that ERCP-related CM adverse reactions are very rare even among patients at risk for CM reaction.

The acute angulation of Roux-en-Y (R-Y) limb precludes endoscopic access for endoscopic retrograde cholangiopancreatography (ERCP) even using a balloon enteroscopy. Here, we describe a case of successful single balloon enteroscopy (SBE)-assisted ERCP using a rendezvous technique in a patient with sharply angulated R-Y limb in a 79-year-old woman who had bile duct stones. Method. At first, a guidewire was passed antegradely through the major papilla after the needle puncture using percutaneous transhepatic biliary drainage technique. A hydrophilic guidewire with an ERCP catheter was antegradely advanced beyond the Roux limb. After a guidewire was firmly grasped by a snare forceps, it was pulled out of the body, resulting that the enteroscope could advance to the papilla. After papillary dilation, complete removal of bile duct stones was achieved without any procedure-related complication. In conclusion, although further study is needed, SBE-assisted ERCP using a rendezvous technique may have a potential for selected patients. PMID:20169091

to determine the incidence, frequency of risk factors, diagnostic aspects (clinics, biochemical, and images) and therapeutic aspects of the choledocholithiasis. Descriptive and prospective analysis of 51 patients who signed informed consent for study of choledocholithiasis by ERCP (endoscopic retrograde cholangiopancreatography). Of the 51 patients, 36 (70.6%) confirmed choledocholithiasis by ERCP. Its incidence was 10.4%. The mean age was 63.75 years, BMI 25.59 kg/m2 and 55.6% were women. Abdominal pain was present in 94.4% of patients. Total bilirubin in the group with choledocholithiasis was 5.8 mg / dl at baseline and 4.2 mg / dl in hospitalization. 11.1% debuted with pancreatitis and 30.6% with cholangitis. In 68.7% of patients with cholangitis was confirmed choledocholithiasis by ERCP. The specificity of ultrasound was 0.80 (95% CI 0.6- 1). The specificity of the nuclear magnetic resonance was 0.25 (95% CI 0.17-0.67). Of the 51 patients with ERCP, 4 (7.80%) do pancreatitis, 1(1.96%) cholangitis and 2 (3.92%) bleeding Choledocholithiasis occurs in older people, female and overweight with an incidence of 10.4%. Abdominal pain is the most common symptom. A total bilirubin more tan 4mg/dl occurs in patients with choledocholithiasis. The complications of choledocholithiasis (pancreatitis and cholangitis) were more frequent than reported in the literature. Both the specificity of cholangitis for choledocholithiasis, the specificity of ultrasound and the specificity of the nuclear magnetic resonance were lower than reported in the literature. ERCP complications were slightly higher than that reported in the literature.

Magnetic resonance cholangiopancreatography (MRCP) is a rapidly evolving non-invasive imaging modality that produces images of the pancreatic duct and binary tree without the need for intravenous or oral contrast. The images are equivalent to those from endoscopic retrograde cholangiopancreatography (ERCP), but the non-invasive acquisition avoids the morbidity and mortality associated with diagnostic ERCP. Magnetic resonance cholangiopancreatography is indicated in patients who require only a diagnostic ERCP, who fail an ERCP or who are unable to undergo ERCP due to altered post-surgical anatomy. Other evolving indications include triaging of patients with obstructive jaundice into percutaneous or endoscopic management drainage pathways depending on the site, length and nature of the duct obstruction, thereby potentially decreasing the number of failed or unsuccessful ERCP. Preoperative identification of anomalous binary anatomy and choledocholithiasis prior to laparoscopic cholecystectomy promise to modify the pre-operative and operative management of the patient in order to minimize the risk of duct injury and unnecessary intra-operative dissection and cholangiography. The advantages of the technique include its non-invasiveness, the absence of contrast administration, its relative operator independence and the ability to evaluate both sides of an obstructed duct, thereby accurately evaluating stricture morphology and length. The disadvantages of MRCP compared to ERCP include its lack of an immediate therapeutic solution to duct obstruction, procedural cost, unit availability and the inability to evaluate patients with pacemakers or ferromagnetic implants.

Rates and severity of PEP, preprocedural and procedural risk factors for the development of PEP, and the effect of pancreatic stents on preventing PEP in high-risk patients. PEP occurred after 47 procedures (prevalence, 10.9%). Thirty-four cases were mild, 9 were moderate, and 4 were severe. There was no mortality. On multiple logistic analysis, pancreatic duct injection (Ppancreatic sphincterotomy (Passociated with PEP. A history of chronic pancreatitis was negatively associated with PEP (Ppancreatic stent was associated with significantly increased rates of PEP in patients with pancreatic duct injection compared with those who had no attempt at stent placement (Ppancreatitis had prophylactic pancreatic stents in place. Retrospective investigation. In the pediatric population, pancreatic duct injection and pancreatic sphincterotomy are associated with significantly increased rates of PEP, whereas a history of chronic pancreatitis is negatively associated. Prophylactic pancreatic stenting is associated with higher rates of PEP in high-risk patients and does not eliminate severe PEP. Copyright © 2015 American Society for Gastrointestinal Endoscopy.

The incidence of duodenal perforation after ERCP ranges from 0.09% to 1.67% and mortality up to 8%. This systematic review was registered in Prospective Register of Systematic Reviews, PROSPERO. Stapfer classification of ERCP-related duodenal perforations was used. The systematic search yielded 259 articles. Most frequent post-ERCP perforation was Stapfer type II (58.4%), type I second most frequent perforation (17.8%) followed by Stapfer type III in 13.2% and type IV in 10.6%. Rate of NOM was lowest in Stapfer type I perforations (13%), moderate in type III lesions (58.1%) and high in other types of perforations (84.2% in type II and 84.6% in IV). In patients underwent early surgical treatment (24 h from ERCP) interventions performed were more complex. In type I lesions post-operative mortality rate was higher in patients underwent late operation (>24 h). In type I lesions, failure of NOM occurred in 42.8% of patients. In type II failure of NOM occurred in 28.9% of patients and in type III there was failure of NOM in only 11.1%, none in type IV. Postoperative mortality after NOM failure was 75% in type I, 22.5% in type II and none died after surgical treatment for failure of NOM in type III perforations. This systematic review showed that in patients with Stapfer type I lesions, early surgical treatment gives better results, however the opposite seems true in Stapfer III and IV lesions.

A descriptive, prospective study was carried out on 451 patients that were attended for endoscopic retrograde cholangiopancreatography at CIMEQ's Hospital from January 2004-March 2006. The sample was constituted by 353 patients with choledocholithiasis suspicion. The information was search in the reports of ERCP and the variables were analyzed with the objective of evaluating the diagnostic possibilities and the therapy for choledocholithiasis by ERCP. Choledocholithiasis was detected in 1/4 of the patients with indication of ERCP, and was more frequent in patients of the female sex and in patients older than 40 years. The jaundice was the main clinical condition that motivated the ERCP in the patients with choledocholithiasis. The diagnostic effectiveness of the alkaline phosphatase and the ultrasound was not high. The treatment of the choledocholithiasis by means of ERCP showed good results and low morbidity

To investigate how rewarming impacts the evolution of EEG background in neonates with hypoxic-ischemic encephalopathy (HIE) undergoing therapeutic hypothermia (TH). We recruited a retrospective cohort of 15 consecutive newborns with moderate (9) and severe (6) HIE monitored with a continuous EEG during TH and at least 12h after its end. EEG background was analyzed using conventional visual and quantitative EEG analysis methods including EEG discontinuity, absolute and relative spectral magnitudes. One patient with seizures on rewarming was excluded from analyses. Visual and quantitative analyses demonstrated significant changes in EEG background from pre- to post-rewarming, characterized by an increased EEG discontinuity, more pronounced in newborns with severe compared to moderate HIE. Neonates with moderate HIE also had an increase in the relative magnitude of slower delta and a decrease in higher frequency theta and alpha waves with rewarming. Rewarming affects EEG background in HIE newborns undergoing TH, which may represent a transient adaptive response or reflect an evolving brain injury. EEG background impairment induced by rewarming may represent a biomarker of evolving encephalopathy in HIE newborns undergoing TH and underscores the importance of continuously monitoring the brain health in critically ill neonates.

2010-01-01

Despite major advances in pain management, cancer pain is managed poorly in 80% of the patients with cancer. Due to deleterious side effects of pharmacology therapy in these people, there is an urgent need for clinical trials of non-pharmacological interventions. To examine the effect of therapeutic touch (TT) on the pain and fatigue of the cancer patients undergoing chemotherapy, a randomized and three-groups experimental study—experimental (TT), placebo (placebo TT), and control (usual care)—was carried out. Ninety patients undergoing chemotherapy, exhibiting pain and fatigue of cancer, were randomized into one of the three groups in the Cancer Center of Imam Khomeini Hospital in Tehran, Iran. Pain and fatigue were measured and recorded by participants before and after the intervention for 5 days (once a day). The intervention consisted of 30 min TT given once a day for 5 days between 10:00 a.m. and 10:30 a.m. The Visual Analogue Scale (VAS) of pain and the Rhoten Fatigue Scale (RFS) were completed for 5 days before and after the intervention by the subjects. The TT (significant) was more effective in decreasing pain and fatigue of the cancer patients undergoing chemotherapy than the usual care group, while the placebo group indicated a decreasing trend in pain and fatigue scores compared with the usual care group.

The patient radiation doses, in conjunction with the operator experience, in therapeutic endoscopic retrograde cholangiopancreatography (ERCP) procedures, performed in our hospital, were obtained. Ninety-six patients participated in the study and were divided into 3 groups, based on the operator experience. The dosimetric indices, fluoroscopy time (FT), cumulative dose (K a,r ) and air kerma-area product (P KA ), were collected. For the total and weight banding group the third quartile values of the distribution of FT, K a,r and P KA were 2.90 and 2.92 min, 6.89 and 6.93 mGy and 1.84 and 1.85 Gycm 2 , respectively, and were comparative or significantly lower than the corresponding values previously reported. Taking as a criterion the operator, the differences in the patient radiation doses were statistically significant, with the highest dose recorded for the operator of the lowest experience degree. The values obtained could contribute in establishing local and national diagnostic reference levels and in optimising ERCP procedure. (authors)

Full Text Available Background : The most common complication of diagnostic and therapeutic endoscopic retrograde cholangiopancreatography (ERCP is acute pancreatitis. A number of therapeutic trials have been studied due to reduce the occurrence of postendoscopic retrograde cholangiopancreatography pancreatitis (PEP but many of them were unsuccessful. Periampullary corticosteroid injection was proposed to use as prophylactic agents for PEP because of its anti-inflammatory property with relative low systemic side effects. Materials and Methods : By conducting a double blinded clinical trial study in a single center university hospital, all patients undergoing therapeutic or diagnostic ERCP in our gastrointestinal endoscopy ward, enrolled the study. During ERCP, we randomly assigned the patients in blocks of 40 to undergo a locally injection of methylprednisolone acetate (corticosteroid group or saline (control group on the major papilla and prospectively evaluated the occurrence of PEP pancreatitis in each groups. Clinical and laboratory findings of acute pancreatitis were collected by means of a validated questionnaire during the procedure and before discharge. At baseline and end of the study, were compared pancreatitis prevalence and also its severity by using Chi-square and t-test statistics. Results : The frequency of moderate to severe PEP pain was not significantly between the placebo and corticosteroid receiving group (13.7% ± 3.2% vs. 9.3% ± 2.1%, respectively; P = 0.8. There is no significant difference in the mean concentration of lipase and amylase between corticosteroid receiving group and placebo receiving group at the first, second, and third time. In the corticosteroid receiving group, 3 patients (10.3% while in the control group, 11 patients (11.3% developed pancreatitis. Conclusion: We found no significant difference in PEP rates and also severity between the corticosteroid and placebo groups. The mean increase in serum amylase and amylase level

Deep biliary cannulation is essential in performing a therapeutic ERCP. Cannulation can be enhanced through the utilization of a pre-cut by means of a needle knife sphincterotomy. Retrospective analysis of the Chris Hani Baragwanath Academic Hospital's ERCP database was performed. All ERCPs performed with the aid of a needle knife were identified and analysed for successful and unsuccessful deep biliary cannulation. 2830 ERCPs were performed during the study period. 369 (13%) required needle knife sphincterotomies and successful deep biliary cannulation was achieved in 229 (62%) of these patients. Repeat ERCPs were performed on 125 (34%) patients. 61 (49%) of the repeat ERCPs were performed because of previously failed cannulation. 34 (56%) of these repeat ERCPs resulted in successful deep biliary cannulation at re-attempt. 99% of successful cannulations at repeat ERCP had had a needle knife sphincterotomy at the first ERCP. Needle knife sphincterotomy improves deep biliary cannulation at initial ERCP and subsequent ERCPs with low incidences of complications.

Full Text Available Background and aims: there is little scientific evidence on the outcomes of endoscopic retrograde cholangiopancreatography (ERCP performed in low-volume hospitals; however, in our country, it is growing up its implementation. The objectives of our study were to evaluate the efficacy and safety of this technique performed by two endoscopists with basic training in a center of this nature and analyze the learning curve in the first procedures. Patients and methods: single-center retrospective study of the first 200 ERCP performed in our hospital (analyzing the evolution between the first 100 and 100 following procedures, comparing them with the quality standards proposed in the literature. Results: from February 2009 to April 2011, we performed 200 ERCP in 169 patients, and the most common indications were: Choledocholithiasis (77 %, tumors (14.5 % and other conditions (8.5 %. The cannulation rate rose from 85 % in the first 100 ERCP to 89 % in the next 100 procedures, clinical success from 81 % to 87 %, decreasing the post-ERCP acute pancreatitis rate from 11 % to 4 %, upper gastrointestinal bleeding (UGIB from 3 % to 2 % and acute cholangitis from 4 % to 1 %. There was a death from a massive UGIB in a cirrhotic patient in the first group of patients and a case of biliary perforation resolved by surgery in the second one. Conclusions: the results obtained after performing 200 procedures support the ability to practice ERCP in low-volume hospitals obtaining levels of efficacy and safety in accordance with published quality standards.Introducción y objetivos: existe poca evidencia científica sobre los resultados de la CPRE realizada en hospitales con bajo volumen, sin embargo su puesta en marcha en nuestro medio es creciente.

Almost all studies on post-ERCP pancreatitis (PEP) have mainly involved patients with biliary diseases rather than chronic pancreatitis (CP), and the concept that CP seems to be a protective factor associated with PEP has not been studied in detail. The aim of this study was to determine the incidence of PEP in patients with CP at different clinical stages and to identify the predictive and protective factors of PEP in a large cohort. In this observational cohort study, medical records of patients with CP (CP group) and biliary diseases (BD group) in a tertiary hospital from January 2011 to May 2015 were examined. The difference in the incidence of PEP between CP group and BD group and the risk of PEP at different clinical stages of CP were calculated by the χ 2 test or the Fisher exact test. The predictive and protective factors for PEP were investigated by univariate and multivariate analysis. In total, 2028 ERCP procedures were performed in 1301 patients with CP and 2000 procedures in 1655 patients with BD. The overall incidence of PEP in CP group (4.5%) was similar to that in the BD group (4.8%; P = .747). However, CP patients had significantly lower rates of moderate and severe attacks (0% vs 1.3%, P pancreatitis, and prior PEP were independent risk factors of PEP, whereas extracorporeal shock wave lithotripsy was a protective factor. Compared with BD patients, CP patients had similar incidence of PEP overall but lower grades of severity. The incidence of PEP in CP patients decreased significantly with disease progression.

Integrative Therapeutic Approaches for the Management and Control of Nausea in Children Undergoing Cancer Treatment: A Systematic Review of Literature.

Science.gov (United States)

Momani, Tha'er G; Berry, Donna L

Chemotherapy-induced nausea and vomiting (CINV) continues to be a common symptom experienced by children undergoing cancer treatment despite the use of contemporary antiemetics. Integrative therapeutic approaches in addition to standard pharmacologic antiemetic regimes offer potential to control CINV. The purpose of this review was to identify current evidence on integrative therapeutic approaches for the control of CINV in children with cancer. Online search engines (PubMed, CINAHL, PsychINFO) were queried using MESH terms. Titles, abstracts, and then full-text articles were reviewed for relevance to the review. The search resulted in 53 studies. Twenty-one studies met our review criteria. Integrative therapies identified included acupuncture/acupressure, aromatherapy, herbal supplements, hypnosis, and other cognitive behavioral interventions. Our review identified little information on the effectiveness and safety of most integrative therapeutic approaches for the control and management of CINV in children with cancer. However, evidence from adult cancer studies and some pediatric studies identify promising interventions for further testing.

How and when should NSAIDs be used for preventing post-ERCP pancreatitis? A systematic review and meta-analysis.

Ignasi Puig

Full Text Available Non-steroidal anti-inflammatory drugs (NSAIDs have been shown to be efficacious to prevent pancreatitis after endoscopic retrograde cholangiopancreatography (ERCP. However, the target patients, the type of NSAID, the route of administration and the time of drug delivery remain unclear, as well as the potential efficacy in reducing the severity of pancreatitis, length of hospital stay and mortality. The objective of the study was to evaluate these questions by performing a systematic review and meta-analysis.Multiple searches were performed in the main databases. Randomized controlled trials (RCTs comparing NSAIDs vs. placebo in the prevention of post-ERCP pancreatitis were included. Primary endpoint of the study was the efficacy for pancreatitis prevention. Sub-analyses were performed to determine the risk reduction in high and low risk patients, and to define optimal time, route of administration, and type of NSAID. Secondary endpoints were safety, moderate to severe pancreatitis prevention and reduction of hospital stay and mortality.Nine RCTs enrolling 2133 patients were included. The risk of pancreatitis was lower in the NSAID group than in the placebo group (RR 0.51; 95%CI 0.39-0.66. The number needed to treat was 14. The risk of moderate to severe pancreatitis was also lower in the NSAID group. (RR 0.46; 95%CI 0.28-0.76. No adverse events related to NSAID use were reported. NSAIDs were effective in both high-risk and unselected patients (RR 0.53; 95%CI 0.30-0.93 and RR 0.57; 95%CI 0.37-0.88. In the subanalyses, only rectal administration of either indomethacin (RR 0.54; 95%CI 0.38-0.75 or diclofenac (RR 0.42; 95%CI 0.21-0.84 was shown to be effective. There were not enough data to perform a meta-analysis in hospital stay reduction. No deaths occurred.A single rectal dose of indomethacin or diclofenac before or immediately after ERCP is safe and prevents procedure-related pancreatitis both in high risk and in unselected patients.

Full Text Available ObjectiveTo investigate the effect of diclofenac sodium on the level of non-steroidal anti-inflammatory drug-activated gene-1 (NAG-1 in patients with post-ERCP pancreatitis (PEP. MethodsA total of 120 patients who underwent ERCP in The First Affiliated Hospital of Anhui Medical University from September 2012 to October 2013 were enrolled and randomly divided into diclofenac sodium group and control group, with 60 patients in each group. The patients in the diclofenac sodium group were given intramuscular injection of Olfen (containing diclofenac sodium 75 mg immediately after ERCP. Blood samples were collected before surgery and at 3 and 24 hours after surgery, and the level of amylase was measured. The incidence of abdominal pain was also observed and the incidence rate of PEP was calculated for both groups. RT-PCR and Western blot were used to measure the mRNA and protein expression of NAG-1 in plasma. An repeated-measures analysis of variance was used for comparison of continuous data, a univariate analysis of variance was used for data meeting the requirements of sphericity test, and the Greenhouse-Geisser correction method was used for data which did not meet the requirements of sphericity test. The chi-square test was used for comparison of categorical data between groups. ResultsThe diclofenac sodium group had a significantly lower incidence rate of PEP than the control group ［6.67% (4/60 vs 20.00% (12/60, χ2=4.62, P=0.03］. The diclofenac sodium group had a significantly lower level of amylase than the control group at 3 and 24 hours after surgery (at 3 hours after surgery: 202.70±120.44 U/L vs 283.57±178.39 U/L, t=2.06, P＜0.05, at 24 hours after surgery: 209.13±157.14 U/L vs 30597±20869 U/L, t=2.03, P＜0.05. At 3 hours after ERCP, the diclofenac sodium group had significant increases in the mRNA and protein expression of NAG-1 in plasma and significantly higher mRNA and protein expression of NAG-1 than the control group

This paper is a report of a study conducted to examine self-reported adherence to a therapeutic regimen for continuous ambulatory peritoneal dialysis. Studies of patients' adherence during dialysis have primarily focused on haemodialysis and have frequently yielded inconsistent results, which are attributed to the inconsistent tools used to measure adherence. Levels of adherence to all four components of the therapeutic regimen (i.e. dietary and fluid restrictions, medication, and the dialysis regimen) among patients receiving peritoneal dialysis have not been examined, especially from a patient perspective. A total population sample was used. A cross-sectional survey was carried out by face-to-face interviews in 2005 in one renal clinic in Hong Kong. A total of 173 patients undergoing peritoneal dialysis (56% of the total population) participated in the study. Patients perceived themselves as more adherent to medication (83%; 95% confidence interval 77-88%) and dialysis (93%; 95% confidence interval 88-96%) prescriptions than to fluid (64%; 95% confidence interval 56-71%) and dietary (38%; 95% confidence interval 30-45%) restrictions. Those who were male, younger or had received dialysis for 1-3 years saw themselves as more non-adherent compared with other patients. Healthcare professionals should take cultural issues into consideration when setting dietary and fluid restriction guidelines. Additional attention and support are required for patients who identify themselves as more non-adherent. To help patients live with end-stage renal disease and its treatment, qualitative research is required to understand how they go through the dynamic process of adherence.

When conventional ERCP methods fail because of periampullary or ductal obstruction, EUS-guided cholangiopancreatography (EUS-CP) may aid in pancreaticobiliary access. To report our experience when using single-operator EUS-CP. An academic tertiary-referral center. Consecutive patients undergoing EUS-CP were prospectively identified. These patients had undergone failed attempt(s) at therapeutic ERCP. A data sheet was used to record indications, reasons for failed ERCP, EUS-CP visualization of the duct of interest, transpapillary or transenteric intervention, clinical follow-up, and complications. Technical success was decompression of the duct of interest. Clinical success was resolution of jaundice or a > or = 50% reduction in pain or narcotics, as applicable. Between February 2003 and June 2007, EUS-CP was attempted in 20 patients (11 men, 9 women; mean [SD] age 58 +/- 14.9 years). Indications included jaundice (n = 8), biliary stones (n = 3), chronic pancreatitis (n = 6), acute pancreatitis (n = 2), and papillary stenosis (n = 1). Reasons for failed ERCP included periampullary mass (n = 8), intradiverticular papillae (n = 4), and pancreatic duct (PD) stricture (n = 7) or stone (n = 1). Technical success was achieved in 18 of 20 patients (90%). Biliary decompression was obtained in 11 of 12 patients (92%) (7 transpapillary and 4 transenteric-transcholedochal). Pancreatic decompression was obtained in 7 of 8 patients (88%) (3 transpapillary, 4 transgastric). On follow-up, clinical improvement was noted in 15 of 20 patients (70%). For treatment of pain associated with chronic pancreatitis, pain scores decreased by a mean of 1.75 (P = .18). Complications (in 2 of 20 [10%]) included perforation (n = 1) and respiratory failure (n = 1). A single-center nonrandomized observational study with a small patient population. At our academic referral center, single-operator EUS-CP provided decompression of obstructed ducts and may be performed after a failed attempt at

Endoscopic retrograde cholangiopancreatography (ERCP), followed by laparoscopic cholecystectomy (LC), remains the standard way of management for patients with cholecystocholedocholithiasis. Laparoendoscopic rendezvous (LERV), a combined procedure for removing the gallbladder laparoscopically and clearing the common bile duct (CBD) endoscopically at the same time, could be an attractive alternative. The aim of this study was to compare LERV with classic ERCP in patients with cholecystocholedocholithiasis. 886 patients with cholecystocholedocholithiasis were treated either with the LERV technique (90 patients), or with the 2-stage approach, which includes preoperative ERCP followed by LC (796 patients). The primary endpoint was any difference in the success of CBD cannulation and clearance; secondary endpoints were the detection of differences in morbidity (especially post-ERCP pancreatitis [PEP]), and the feasibility of the two approaches. Successful cannulation of the CBD was more frequent with conventional ERCP compared with the LERV technique (89.8% vs. 75.5%, P=0.0001). LERV appears to be as effective as conventional ERCP for complete CBD clearance (85.5% vs. 82.8%, P<0.1). None of the patients in the LERV group had an episode of clinical PEP, whereas in the conventional ERCP group there were 23 episodes of PEP and one death. The median amylase level was higher in patients undergoing conventional ERCP group compared to patients in LERV group. Classic ERCP has a higher rate of successful CBD cannulation and a similar rate of CBD clearance compared to LERV.

Background/Aims Endoscopic retrograde cholangiopancreatography (ERCP) can be an effective treatment for bile leakage after liver transplantation. We evaluated the efficacy of endoscopic treatment in liver transplantation in patients who developed bile leaks. Methods Forty-two patients who developed bile leaks after liver transplantation were included in the study. If a bile leak was observed on ERCP, a sphincterotomy was performed, and a nasobiliary catheter was then inserted. If a bile leak was accompanied by a bile duct stricture, either the stricture was dilated with balloons, followed by nasobiliary catheter insertion across the bile duct stricture, or endoscopic retrograde biliary drainage was performed. Results In the bile leakage alone group (22 patients), endoscopic treatment was technically successful in 19 (86.4%) and clinically successful in 17 (77.3%) cases. Among the 20 patients with bile leaks with bile duct strictures, endoscopic treatment was technically successful in 13 (65.0%) and clinically successful in 10 (50.0%) cases. Among the 42 patients who underwent ERCP, technical success was achieved in 32 (76.2%) cases and clinical success was achieved in 27 (64.3%) cases. Conclusions ERCP is an effective and safe therapeutic modality for bile leaks after liver transplantation. ERCP should be considered as an initial therapeutic modality in post-liver transplantation patients. PMID:25717048

Endoscopic retrograde cholangiopancreatography (ERCP) is performed for various diseases. The aim of this study is to evaluate the difference of dose-area product (DAP) during the ERCP procedures according to location of the lesion. We performed a retrospective study of consecutive 217 therapeutic ERCP examinations performed between November 2014 and April 2015 at a tertiary care center. ERCP procedures divided into two groups according to location of the lesion identified on imaging: lesions in the common hepatic duct (CHD) or the common bile duct (CBD) and lesions in the hepatic hilum or the intrahepatic duct (IHD). The mean DAP of the hilum-IHD group (48.7 Gy cm 2 ) was significantly higher than that of the CBD-CHD group (34.9 Gy cm 2 ) (P = 0.003). Radiation exposure during ERCP was significantly different according to location of bile duct lesion. (authors)

Numerous clinical trials to improve the success rate of biliary access in difficult biliary cannulation (DBC) during ERCP have been reported. However, standard guidelines or sequential protocol analysis according to different methods are limited in place. We planned to investigate a sequential protocol to facilitate selective biliary access for DBC during ERCP. This prospective clinical study enrolled 711 patients with naïve papillae at a tertiary referral center. If wire-guided cannulation was deemed to have failed due to the DBC criteria, then according to the cannulation algorithm early precut fistulotomy (EPF; cannulation time > 5 min, papillary contacts > 5 times, or hook-nose-shaped papilla), double-guidewire cannulation (DGC; unintentional pancreatic duct cannulation ≥ 3 times), and precut after placement of a pancreatic stent (PPS; if DGC was difficult or failed) were performed sequentially. The main outcome measurements were the technical success, procedure outcomes, and complications. Initially, a total of 140 (19.7%) patients with DBC underwent EPF (n = 71) and DGC (n = 69).

The nature of end-stage renal disease and the need for continuous ambulatory peritoneal dialysis require patients to manage various aspects of the disease, its symptoms and treatment. After attending a training programme, patients are expected to adhere to the renal therapeutic regimen and manage their disease with the knowledge and skills learned. While patients are the stakeholders of their health and related behaviour, their perceptions of adherence and how they adhere to their renal therapeutic regimen remains unexplored. To understand adherence from patients' perspectives and to describe changes in adherence to a therapeutic regimen among patients undergoing continuous ambulatory peritoneal dialysis. This study used a mixed methods design with two phases - a survey in phase I and semi-structured interviews in phase II. This paper presents phase II of the study. The study was conducted at a renal unit of an acute hospital in Hong Kong. Based on the phase I survey results, maximum variation sampling was employed to purposively recruit 36 participants of different genders (18 males, 18 females), ages (35-76 years), and lengths of dialysis experience (11-103 months) for the phase II interviews. Data were collected by tape-recorded semi-structured interviews. Content analysis was employed to analyse the transcribed data. Data collection and analysis were conducted simultaneously. Adherence was a dynamic process with three stages. At the stage of initial adherence, participants attempted to follow instructions but found that strict persistent adherence was impossible. After the first 2-6 months of dialysis, participants entered the stage of subsequent adherence, when they adopted selective adherence through experimenting, monitoring and making continuous adjustments. The stage of long-term adherence commenced after 3-5 years of dialysis, when participants were able to assimilate the modified therapeutic regimen into everyday life. The process of adherence was

Full Text Available Pancreatic fistula is a known complication of distal pancreatectomy. Endotherapy with pancreatic duct stent placement and pancreatic sphincterotomy has been shown to be effective in its management; however, experience of endotherapy in the management of this complication has not been extensively reported from the United States. Preoperative endoscopic retrograde cholangiopancreatography (ERCP with pancreatic stent placement has also been proposed to prevent this complication after distal pancreatectomy. In our cohort of 59 patients who underwent distal pancreatectomy, 13 (22% developed a pancreatic fistula in the immediate postoperative period, of whom 8 (14% patients (5 female, mean age 52 years were referred for an ERCP because of ongoing symptoms related to the pancreatic fistula. The pancreatic fistula resolved in all patients after a median duration of 62 days from the index ERCP. The median number of ERCPs required to document resolution of the pancreatic fistula was 2. Although a sizeable percentage of patients develop a pancreatic fistula after distal pancreatectomy, only a small percentage of patients require ERCP for management of this complication. Given the high success rate of endotherapy in resolving pancreatic fistula and the fact that the majority of patients who undergo distal pancreatectomy never require an ERCP, performing ERCP for prophylactic pancreatic duct stent prior to distal pancreatectomy might not be necessary.

Online social networking is increasingly being used among medical practitioners. However, few studies have evaluated its use in therapeutic endoscopy. Here, we aimed to analyze the shared topics and activities of a group of endoscopic retrograde cholangiopancreatography (ERCP) doctors in a social networking-based endoscopic retrograde cholangiopancreatography discussion group (EDG). Six ERCP trainers working in Xijing Hospital and 48 graduated endoscopists who had finished ERCP training in the same hospital were invited to join in EDG. All group members were informed not to divulge any private information of patients when using EDG. The activities of group members on EDG were retrospectively extracted. The individual data of the graduated endoscopists were collected by a questionnaire. From June 2014 to May 2015, 6924 messages were posted on EDG, half of which were ERCP related. In total, 214 ERCP-related topics were shared, which could be categorized into three types: sharing experience/cases (52.3%), asking questions (38.3%), and sharing literatures/advances (9.3%). Among the 48 graduated endoscopists, 21 had a low case volume of less than 50 per year and 27 had a high volume case volume of 50 or more. High-volume graduated endoscopists posted more ERCP-related messages (P=0.008) and shared more discussion topics (P=0.003) compared with low-volume graduated endoscopists. A survey showed that EDG was useful for graduated endoscopists in ERCP performance and management of post-ERCP complications, etc. A wide range of ERCP-related topics were shared on the social networking-based EDG. The ERCP-related behaviors on EDG were more active in graduated endoscopists with an ERCP case volume of more than 50 per year.

Pancreatic stone and treatment using ERCP and ESWL procedures: a case study and review.

Pancreatic duct stones are found in 22 to 60% of patients with chronic pancreatitis (CP). The stones can lead to obstruction of the outflow of pancreatic secretions causing increased intraductal pressure. The pancreas is relatively noncompliant. Therefore the rise in intraductal pressure can induce tissue hypertension and ischemia. This can be a major factor causing pain in patients with CP. This hypothesis is supported by the observation that symptoms may improve following pancreatic duct drainage. A 62-year-old woman presented with persistent epigastric pain. Investigations revealed calcifications within the main pancreatic duct and head of the gland. Treatment with endoscopic retrograde cholangiopancreatography (ERCP) and extracorporeal shock wave lithotripsy (ESWL) achieved a good outcome. Standard endoscopic removal of the stones proved impossible so treatment with ESWL was undertaken. Following fragmentation, the calculi and fragments passed spontaneously or were removed endoscopically. If pancreatic stones cannot be removed endoscopically, ESWL should be considered prior to surgery.

Endoscopic ultrasonography (EUS) is an established diagnostic modality for diagnosing common bile duct (CBD) stones. Its use has led to a reduction in the number of endoscopic retrograde cholangiopancreatography (ERCP) procedures performed for suspected choledocholithiasis. We aimed to explore the role of EUS in detecting CBD stones and/or sludge in common gastroenterology practice. We reviewed case records of 268 consecutive patients who underwent (EUS) procedures performed to confirm or rule out the presence of CBD stones and/or sludge between November 2006 and January 2011 in the Reinier de Graaf Hospital, Delft, The Netherlands, which is a nonacademic community hospital. On the basis of EUS findings, 169 of 268 (63%) patients did not undergo ERCP and were therefore not exposed to its risk of complications. Patients with positive findings on EUS (n=99) all underwent ERCP and endoscopic sphincterotomy. Only 57 of 99 (58%) had positive findings at ERCP. The main contributing factors to this finding seem to be time interval between EUS and ERCP and the type of CBD content (i.e. sludge, one CBD stone or more than one CBD stone) described. In our common gastroenterology practice, EUS plays an important role in selecting patients suspected to have CBD stones or sludge for ERCP. Much is to be learned about the probability of spontaneous passage of CBD stones and sludge into the duodenum.

AIM: The optimal treatment for bile duct stones (in terms of cost, complications and accuracy) is unclear. The aim of our study was to determine the predictive factors for preoperative endoscopic retrograde cholangiopancreatography (ERCP). METHODS: Patients undergoing preoperative ERCP ( ≤ 90 d before laparoscopic cholecystectomy) were evaluated in this retrospective study from the 1st of January 1996 to the 31st of December 2002. The indications for ERCP were elevated serum bilirubin, elevated liver function tests (LFT), dilated bile duct ( ≥ 8 mm) and/or stone at US examination, coexisting acute pancreatitis and/or acute pancreatitis or jaundice in patient’s history. Suspected prognostic factors and the combination of factors were compared to the result of ERCP. RESULTS: Two hundred and six preoperative ERCPs were performed during the observed period. The rate of successful cannulation for ERC was (97.1%). Bile duct stones were detected in 81 patients (39.3%), and successfully removed in 79 (97.5%). The number of prognostic factors correlated with the presence of bile duct stones. The positive predictive value for one prognostic factor was 1.2%, for two 43%, for three 72.5%, for four or more 91.4%. CONCLUSION: Based on our data preoperative ERCP is highly recommended in patients with three or more positive factors (high risk patients). In contrast, ERCP is not indicated in patients with zero or one factor (low risk patients). Preoperative ERCP should be offered to patients with two positive factors (moderate risk patients), however the practice should also be based on the local conditions (e.g. skill of the endoscopist, other diagnostic tools).

Objective: To evaluate the role of endoscopic retrograde cholangiopancreatography (ERCP) in patients with obstructive jaundice. Results: Of the 226 patients, 117 (51.8%) were males, and 109 (48.2%) females, their mean age being 51.8 plus minus 16.6 years. Common bile and pancreatic ducts were visualized in 81.8% and 68.1% patients respectively. Growth/masses and stones were commonest causes of obstructive jaundice. Choledocholithias was common in males, while biliary channel related growth/masses were common in females (p-value = 0.03). Common bile duct stone clearance rate was 88%, stenting was highly successful in patients with growth and strictures. ERCP related complications were noted in 11 (4.8%) patients. Conclusion: ERCP is an important diagnostic and therapeutic modality for evaluation of patients with obstructive jaundice. Growth/masses and stones are common causes of obstructive jaundice, which can be diagnosed and treated with ERCP. (author)

The probability that a patient has common bile duct stones (CBDS) is a key factor in determining diagnostic and treatment strategies. This prospective cohort study evaluated the accuracy of clinical models in predicting CBDS for patients who will undergo cholecystectomy for lithiasis. From October 2005 until September 2006, 335 consecutive patients with symptoms of gallstone disease underwent cholecystectomy. Statistical analysis was performed on prospective patient data obtained at the time of first presentation to the hospital. Demonstrable CBDS at the time of endoscopic retrograde cholangiopancreatography (ERCP) or intraoperative cholangiography (IOC) was considered the gold standard for the presence of CBDS. Common bile duct stones were demonstrated in 53 patients. For 35 patients, ERCP was performed, with successful stone clearance in 24 of 30 patients who had proven CBDS. In 29 patients, IOC showed CBDS, which were managed successfully via laparoscopic common bile duct exploration, with stone extraction at the time of cholecystectomy. Prospective validation of the existing model for CBDS resulted in a predictive accuracy rate of 73%. The new model showed a predictive accuracy rate of 79%. Clinical models are inaccurate in predicting CBDS in patients with cholelithiasis. Management strategies should be based on the local availability of therapeutic expertise.

In patients with haemorrhagic necrotizing pancreatitis who are scheduled for surgery, we have been carrying out a preoperative retrograde investigation of the pancreatic duct system for the past 3 months. The results in, to date, ten patients, all of whom survived their severe illness, revealed four different morphological findings of importance for the surgical tactic. 1. A normal pancreatic duct system with no signs of fistulae: only peripancreatic necrosectomy is required. 2. Contrast medium leaks via a ductal fistula: left resection, including the removal of the fistulous area, must be done. 3. Normal duct system with complete segmental parenchymal staining, representing total necrosis in this region: left resection of the pancreas. 4. Duodenoscopically demonstrable perforation into the duodenum of a necrotic cavity in the head of the pancreas: conservative management only, no surgery, since this lesions, resulting in drainage of the necrotic cavity into the bowel, permits self-healing, while the site of the perforation within the necrotic wall cannot be dealt with by surgery. The experience gained so far indicates that the surgical tactic can be determined with greater selectivity by the use of ERCP.

Diagnostic yield of brush cytology for biliary stenosis during ERCP Rentabilidad diagnóstica de la citología por cepillado de las estenosis biliares durante la CPRE

2009-06-01

Full Text Available Aim: to evaluate the diagnostic yield of brush cytology for biliary strictures detected on ERCP when a systematic approach is used. Patients and methods: data on 62 consecutive patients with a biliary stricture on ERCP were collected. Cytological samples were processed immediately after brushing in the endoscopy room, and all were analyzed by the same pathologist. For the statistical analysis specimens were classified as positive, negative, suspicious for malignancy (presence of atypias, and unsatisfactory for evaluation. Final diagnosis was based on either histopathologic (surgery or biopsies by other techniques or clinical/radiographic diagnosis. Results: a total of 71 cytological specimens were included. Definite diagnosis was malignancy in 49 samples, and benign stricture in 22. Three samples were excluded because of insufficient material or processing artifacts. The sensitivity of biliary brushing was 62% (95% CI 0.47-0.77, specificity was 100%, positive predictive value was 100%, and negative predictive value was 58% (95% CI 0.43-0.75. When suspicious samples were included as malignant, sensitivity was 67% (95% CI 0.54-0.81 without changes in the remaining parameters. Eight patients underwent more than one ERCP. Repeated brush cytology exams in these patients yielded a definitive diagnosis in every case. Conclusions: brush cytology has intermediate sensitivity with a high specificity. A systematic approach with a dedicated pathologist and the inclusion of significant atypias as malignant results improves sensitivity. Due to its simplicity brush cytology should be performed in all cases of biliary strictures detected on ERCP, and in case of repeated ERCPs additional cytology brushings are recommended.Objetivo: evaluar la rentabilidad de la citología por cepillado de las estenosis biliares diagnosticadas por CPRE cuando se aplica una metodología sistemática.

Endoscopic retrograde cholangiopancreatography (ERCP) is a common procedure that, in the United States, is traditionally performed by gastroenterologists. We hypothesized that when performed by well-trained surgeons, ERCP can be performed safely and effectively. The objectives of the study were to assess the rate of successful cannulation of the duct of interest and to assess the 30-day complication and mortality rates. We retrospectively reviewed the charts of 1858 patients who underwent 2392 ERCP procedures performed by five surgeons between August 2003 and June 2016 in two centers. Demographic and historical data, indications, procedure-related data and 30-day complication and mortality data were collected and analyzed. The mean age was 53.4 (range 7-102) years and 1046 (56.3%) were female. 1430 (59.8%) of ERCP procedures involved a surgical endoscopy fellow. The most common indication was suspected or established uncomplicated common bile duct stones (n = 1470, 61.5%), followed by management of an existing biliary or pancreatic stent (n = 370, 15.5%) and acute biliary pancreatitis (n = 173, 7.2%). A therapeutic intervention was performed in 1564 (65.4%), a standard sphincterotomy in 1244 (52.0%), stent placement in 705 (29.5%) and stone removal in 638 (26.7%). When cannulation was attempted, the rate of successful cannulation was 94.1%. When cannulation was attempted during the patient's first ERCP the cannulation rate was 92.4%. 94 complications occurred (5.4%); the most common complication was post-ERCP pancreatitis in 75 (4.2%), significant gastrointestinal bleeding in 7 (0.4%), ascending cholangitis in 11 (0.6%) and perforation in 1 (0.05%). 11 mortalities occurred (0.5%) but none of which were ERCP-related. When performed by well-trained surgical endoscopists, ERCP is associated with high success rate and acceptable complication rates consistent with previously published reports and in line with societal guidelines.

Therapeutic applications of radiopharmaceuticals

Baker, W.J.; Datz, F.L.; Beightol, R.W.

Whether a radiopharmaceutical has diagnostic or therapeutic application depends on both the isotope and pharmaceutical used. For diagnostic applications, the isotope should undergo only γ-decay, since usually only γ-radiation is detected by nuclear medicine cameras. The half-life should be just long enough to allow the procedure to be performed. In contrast, the isotope needed for therapeutic purposes should have particulate radiation, such as a β-particle (electron), since these are locally absorbed an increase the local radiation dose. γ-Radiation, which penetrates the tissues, produces less radiation dose than do Β-particles. Several references dealing with radioactive decay, particulate interactions, and diagnostic and therapeutic applications of radiopharmaceuticals are available. Radiopharmaceuticals can legally be used only by physicians who are qualified by specific training in the safe handling of radionuclides. The experience and training of these physicians must be approved by the Nuclear Regulatory Commission or Agreement State Agency authorized to license the use of radiopharmaceuticals. A list of all byproduct material and procedures is available in the Code of Federal Regulations. Of the many radiopharmaceuticals available for diagnostic and therapeutic use, only those commonly used are discussed in this chapter

To compare the clinical outcomes of patients who did and did not receive palliative care consultation among those who experienced out-of-hospital cardiac arrest and underwent therapeutic hypothermia. We identified patients at a single academic medical center who had undergone therapeutic hypothermia after out-of-hospital cardiac arrest between 2009 and 2013. We performed a retrospective chart review for demographic data, hospital and critical care length of stay, and clinical outcomes of care. We reviewed the charts of 62 patients, of which 35 (56%) received a palliative care consultation and 27 (44%) did not. Palliative care consultation occurred an average of 8.3 days after admission. Patients receiving palliative care consultation were more likely to have a do-not-resuscitate (DNR) order placed (odds ratio: 2.3, P care or not (16.7 vs 17.1 days, P = .90). Intensive care length of stay was also similar (11.3 vs 12.6 days, P = .55). Palliative care consultation was underutilized and utilized late in this cohort. Palliative consultation was associated with DNR orders but did not affect measures of utilization such as hospital and intensive care length of stay.

Phenotypic Plasticity Determines Cancer Stem Cell Therapeutic Resistance in Oral Squamous Cell Carcinoma

Full Text Available Cancer stem cells (CSCs drive tumour spread and therapeutic resistance, and can undergo epithelial-to-mesenchymal transition (EMT and mesenchymal-to-epithelial transition (MET to switch between epithelial and post-EMT sub-populations. Examining oral squamous cell carcinoma (OSCC, we now show that increased phenotypic plasticity, the ability to undergo EMT/MET, underlies increased CSC therapeutic resistance within both the epithelial and post-EMT sub-populations. The post-EMT CSCs that possess plasticity exhibit particularly enhanced therapeutic resistance and are defined by a CD44highEpCAMlow/−CD24+ cell surface marker profile. Treatment with TGFβ and retinoic acid (RA enabled enrichment of this sub-population for therapeutic testing, through which the endoplasmic reticulum (ER stressor and autophagy inhibitor Thapsigargin was shown to selectively target these cells. Demonstration of the link between phenotypic plasticity and therapeutic resistance, and development of an in vitro method for enrichment of a highly resistant CSC sub-population, provides an opportunity for the development of improved chemotherapeutic agents that can eliminate CSCs.

Therapy by low-level laser (LLL) or ultrasound (US) are commonly used as treatment after nerve crush. The aim of this study was to determine the effectiveness of such treatments to repair the neuronal cytoskeleton evaluating the variation in the number of neurofilaments. For this an experimental design was performed, which involved 30 rats divided into 6 groups: 1 - control healthy; 2 - control injured; 3 - irradiated by LLL 2 J/cm2; 4 - irradiated by LLL 10 J/cm2; 5 - irradiated by US 0.5 W/cm2 and 6 - irradiated by US 1W/cm2. With the exception of group 1 all specimens were anesthetized and underwent right sciatic nerve compression using 40N pressure for 45 seconds. Twenty-four hours after compression irradiation was started by LLL and US according protocol. In our research we found that the increase in the number of neurofilaments was related to the applied dose of LLL and US. The average value of neurofilaments / 0.25 mm2 obtained in each group was: 1 - 128; 2-100; 3-156; 4-140; 5-100; 6-148. We concluded that the application of LLL and therapeutic US increases the number of neurofilaments in rat sciatic nerve undergoing neuropraxia, with LLL being more effective compared to the US. Furthermore we concluded that the effectiveness of therapies to induce regeneration of injured nerve is related to the type of protocol used, demonstrating the need to establish an adequate radiation dose with the purpose of obtaining the best therapeutic response, thus achieving successful treatment [es

Cell therapy using macrophages requires large amounts of cells, which are difficult to collect from patients. Patients undergoing peritoneal dialysis (PD) discard huge numbers of peritoneal macrophages in dialysate daily. Macrophages can be modulated to become regulatory macrophages, which have shown great promise as a therapeutic strategy in experimental kidney disease and human kidney transplantation. This study aimed to examine the potential of using peritoneal macrophages (PMs) from peritoneal dialysate to treat kidney disease. Monocytes/macrophages accounted for >40% of total peritoneal leukocytes in both patients and mice undergoing PD. PMs from patients and mice undergoing PD were more mature than peripheral monocytes/macrophages, as shown by low expression of C-C motif chemokine receptor 2 (CCR2) and morphological changes during in vitro culture. PMs from patients and mice undergoing PD displayed normal macrophage function and could be modulated into a regulatory (M2) phenotype. In vivo, adoptive transfer of peritoneal M2 macrophages derived from PD mice effectively protected against kidney injury in mice with adriamycin nephropathy (AN). Importantly, the transfused peritoneal M2 macrophages maintained their M2 phenotype in kidney of AN mice. In conclusion, PMs derived from patients and mice undergoing PD exhibited conventional macrophage features. Peritoneal M2 macrophages derived from PD mice are able to reduce kidney injury in AN, suggesting that peritoneal macrophages from patients undergoing PD may have the potential for clinical therapeutic application.

Full Text Available Pancreatitis is the most common complication of endoscopic retrograde cholangiopancreatography (ERCP. Several patients´ or procedure related risk factors for post-ERCP pancreatitis (PEP have been suggested. The aim of this study was to validate the risk factors for PEP in a high-volume center.All patients undergoing first time ERCP at a tertiary referral center between December 2010 and October 2013 were retrospectively included. PEP was defined according to the Atlanta Classification.344 patients were included in the final analysis. The risk to develop PEP was increased in patients with chronic pancreatitis (odds ratio 3.7 and after inadvertent cannulation of the pancreatic duct (odds ratio 2.2, which occurred in 26.5% of the patients. Inadvertent cannulation occurred significantly more frequently in patients with difficult cannulation of the papilla duodeni major (odds ratio 12.7; p<0.001. ERCP on call was associated with an increased risk for difficult cannulation (odds ratio 3.0.Inadvertent cannulation of the pancreatic duct is a procedure related risk factor for PEP. Measurements on preventing inadvertent cannulation of the pancreatic duct should be established and studies on prophylactic measurements should focus particularly on patients with inadvertent cannulation of the pancreatic duct.

Diclofenac and indomethacin are the most studied drugs for preventing post-ERCP pancreatitis (PEP). However, there are no prospective, randomized multicenter trials with a sufficient number of patients for correct evaluation of their efficacy. Our aim was to evaluate all prospective trials published in full text that studied the efficacy of diclofenac or indomethacin and were controlled with placebo or non-treatment for the prevention of PEP in adult patients undergoing ERCP. Systematic search of databases (PubMed, Scopus, Web of Science, Cochrane) for relevant studies published from inception to 30 June 2016. Our meta-analysis of 4741 patients from 17 trials showed that diclofenac or indomethacin significantly decreased the risk ratio (RR) of PEP to 0.60 (95% confidence interval [CI], 0.46-0.78; P = .0001), number needed to treat (NNT) was 20, and the reduction of RR of moderate to severe PEP was 0.64 (95% CI, 0.43-0.97; P = .0339). The efficacy of indomethacin compared with diclofenac was similar (P = .98). The efficacy of indomethacin or diclofenac did not differ according to timing (P = .99) or between patients with average-risk and high-risk for PEP (P = .6923). The effect of non-rectal administration of indomethacin or diclofenac was not significant (P = .1507), but the rectal route was very effective (P = .0005) with an NNT of 19. The administration of indomethacin or diclofenac was avoided in patients with renal failure. Substantial adverse events were not detected. The use of rectally administered diclofenac or indomethacin before or closely after ERCP is inexpensive and safe and is recommended in every patient (without renal failure) undergoing ERCP.

Full Text Available We extended our recent modification of the power spectral estimation approach to quantify spectral coherence. We tested both the standard and the modified approaches on simulated data which showed that the modified approach was highly specific and sensitive to the coupling introduced in the simulation while the standard approach lacked these features. We also applied the modified and standard approaches to quantify the pressure passivity in 4 infants receiving therapeutic hypothermia. This was done by measuring the coupling between continuous cerebral hemoglobin differences and mean arterial blood pressure. Our results showed that the modified approach identified a lower pressure passivity index (PPI, percent time the coherence was above a predefined threshold than the standard approach ($P=0.0027$.

In patients with Roux-en-Y hepaticojejunostomy (HJ with R-Y) and Whipple resection, endoscopic retrograde cholangiopancreatography (ERCP) can be challenging. We report our experience with ERCP using balloon-assisted enteroscopy (BAE) (BAE-ERCP) in patients with HJ with R-Y, and Whipple resection. BAE-ERCP procedures were carried out in 62 patients (HJ with R-Y:Whipple resection=34:28). Overall, the rates of reaching the anastomosis were 85.3% (29/34) in HJ with R-Y and 96.4% (27/28) in Whipple resection. In terms of HJ with R-Y, insertion success rate by standard single-balloon enteroscopy (SBE) was 89.3% (25/28). Insertion success rate by short BAE, including SBE and double-balloon enteroscopy (DBE), was 50% (3/6). There was a statistically significant difference of insertion success rate between standard long BE and short BE (P=0.021). However, in the Whipple patients, insertion success rate by standard and short SBE was 93.8% (15/16) and 91.7% (11/12), respectively. Initial insertion success rate by short BAE in Whipple patients was significantly higher than in HJ with R-Y (91.7% vs 50%, P=0.045). Therapeutic interventions included dilation of anastomosis stricture, stone extraction, endoscopic mechanical lithotripsy, biliary stent placement, stent extraction, endoscopic nasobiliary drainage, direct cholangioscopy, and electrohydraulic lithotripsy. Our HJ with R-Y series and Whipple series treatment success rate was 90% (18/20) and 95.0% (19/20), respectively. BAE-ERCP enabled ERCP to be carried out in patients with HJ. It is considered safe and feasible. Further experience and device improvement are needed. © 2014 The Authors. Digestive Endoscopy © 2014 Japan Gastroenterological Endoscopy Society.

Preterm neonates below 30 weeks' gestational age undergo numerous painful procedures. Many management approaches are not appropriate for this population. Therapeutic Touch, an alternative approach based on the theory of energy medicine, has been shown to promote physiological stability in preterm neonates and reduce pain in some adult studies. The objective was to determine whether Therapeutic Touch is efficacious in decreasing pain in preterm neonates. Infants Touch (n = 27) with infant behind curtains, leaving the curtained area for the heel lance, performed by another. In the sham condition (n = 28), the therapist stood by the incubator with hands by her side. The Premature Infant Pain Profile was used for pain response and time for heart rate to return to baseline for recovery. Heart rate variability and stress response were secondary outcomes. There were no group differences in any of the outcomes. Mean Premature Infant Pain Profile scores across 2 minutes of heel lance procedure in 30-second blocks ranged from 7.92 to 8.98 in the Therapeutic Touch group and 7.64 to 8.46 in the sham group. Therapeutic Touch given immediately before and after heel lance has no comforting effect in preterm neonates. Other effective strategies involving actual touch should be considered.

Patients undergoing lobectomy are at significantly increased risk of lung injury. One-lung ventilation is the most commonly used technique to maintain ventilation and oxygenation during the operation. It is a challenge to choose an appropriate mechanical ventilation strategy to minimize the lung injury and other adverse clinical outcomes. In order to understand the available evidence, a systematic review was conducted including the following topics: (I) protective ventilation (PV); (II) mode of mechanical ventilation [e.g., volume controlled (VCV) versus pressure controlled (PCV)]; (III) use of therapeutic hypercapnia; (IV) use of alveolar recruitment (open-lung) strategy; (V) pre-and post-operative application of positive end expiratory pressure (PEEP); (VI) Inspired Oxygen concentration; (VII) Non-intubated thoracoscopic lobectomy; and (VIII) adjuvant pharmacologic options. The recommendations of class II are non-intubated thoracoscopic lobectomy may be an alternative to conventional one-lung ventilation in selected patients. The recommendations of class IIa are: (I) Therapeutic hypercapnia to maintain a partial pressure of carbon dioxide at 50-70 mmHg is reasonable for patients undergoing pulmonary lobectomy with one-lung ventilation; (II) PV with a tidal volume of 6 mL/kg and PEEP of 5 cmH 2 O are reasonable methods, based on current evidence; (III) alveolar recruitment [open lung ventilation (OLV)] may be beneficial in patients undergoing lobectomy with one-lung ventilation; (IV) PCV is recommended over VCV for patients undergoing lung resection; (V) pre- and post-operative CPAP can improve short-term oxygenation in patients undergoing lobectomy with one-lung ventilation; (VI) controlled mechanical ventilation with I:E ratio of 1:1 is reasonable in patients undergoing one-lung ventilation; (VII) use of lowest inspired oxygen concentration to maintain satisfactory arterial oxygen saturation is reasonable based on physiologic principles; (VIII) Adjuvant drugs

Molecular and histopathological profiling have classified breast cancer into multiple sub-types empowering precision treatment. Although estrogen receptor (ER) and human epidermal growth factor receptor (HER2) are the mainstay therapeutic targets in breast cancer, the androgen receptor (AR) is evolving as a molecular target for cancers that have developed resistance to conventional treatments. The high expression of AR in breast cancer and recent discovery and development of new nonsteroidal drugs targeting the AR provide a strong rationale for exploring it again as a therapeutic target in this disease. Ironically, both nonsteroidal agonists and antagonists for the AR are undergoing clinical trials, making AR a complicated target to understand in breast cancer. This review provides a detailed account of AR’s therapeutic role in breast cancer. PMID:27918430

There is still uncertainty regarding the efficacy and optimal modalities of extracorporeal shock wave lithotripsy (ESWL) in the treatment of chronic pancreatitis. The aims of the present study were to assess the safety and the efficacy of ESWL, either alone or followed by therapeutic endoscopic retrograde cholangiopancreatography (adjuvant ERCP) and to determine predictive factors of efficacy, in a real-life setting. This study included all consecutive patients who underwent an ESWL in a single University Hospital between 2001 and 2012. The indication for ESWL was obstructive stone(s) of the main pancreatic duct resulting in either painful chronic pancreatitis or recurrent acute pancreatitis. Success was defined by resolution of pain, no analgesic treatment, no acute pancreatitis and no surgical treatment for chronic pancreatitis 6 months after the ESWL. One hundred and forty-six patients were studied; 6/146 (4%) had a complication of ESWL. Among the 132 patients in whom follow-up was completed, 91 (69%) had an adjuvant ERCP. After 6 months of follow-up, 100/132 (76%) patients achieved success. In multivariate analysis, the single significant predictive factor of the success of the ESWL treatment was chronic pain (p = 0.03). Patients who had chronic pain and needed opioid treatment had less chance of success than patients without chronic pain (OR 95%CI 0.31 [0.07-1.14]). We found no difference in the success rates between patients who underwent adjuvant ERCP and those who had ESWL only (p = 0.93). This study shows that the ESWL is a safe and effective treatment for patients with chronic pancreatitis and obstructive stones within the main pancreatic duct. Systematic association with therapeutic ERCP appears to provide no additional benefit and is therefore not recommended.

Aspirin in the Management of Patients with Prostate Cancer Undergoing Radiotherapy: Friend or Foe?

Mascan, Bianca; Marignol, Laure

2018-04-01

Aspirin has cyclooxygenase-2 (COX2)-mediated anti-inflammatory and anti-coagulant properties that may confer a positive effect in preventing and limiting the progression of prostate cancer. Prostate cancer has been shown to have poor treatment outcomes due to therapeutic resistance; therefore, COX2 inhibition caused by aspirin could represent an opportunity to augment current therapies. This is particularly of interest to patients undergoing radiation therapy (RT) where inflammation is a common side-effect. This review discusses the evidence for the potential role of aspirin in the management of patients with prostate cancer undergoing RT.

Pancreatitis is the most common complication of endoscopic retrograde cholangiopancreatography (ERCP). Several patients´ or procedure related risk factors for post-ERCP pancreatitis (PEP) have been suggested. The aim of this study was to validate the risk factors for PEP in a high-volume center. All patients undergoing first time ERCP at a tertiary referral center between December 2010 and October 2013 were retrospectively included. PEP was defined according to the Atlanta Classification. 344 patients were included in the final analysis. The risk to develop PEP was increased in patients with chronic pancreatitis (odds ratio 3.7) and after inadvertent cannulation of the pancreatic duct (odds ratio 2.2), which occurred in 26.5% of the patients. Inadvertent cannulation occurred significantly more frequently in patients with difficult cannulation of the papilla duodeni major (odds ratio 12.7; passociated with an increased risk for difficult cannulation (odds ratio 3.0). Inadvertent cannulation of the pancreatic duct is a procedure related risk factor for PEP. Measurements on preventing inadvertent cannulation of the pancreatic duct should be established and studies on prophylactic measurements should focus particularly on patients with inadvertent cannulation of the pancreatic duct.

Hypovitaminosis D in patients undergoing kidney transplant: the importance of sunlight exposure

Directory of Open Access Journals (Sweden)

Cristiane F. Vilarta

Full Text Available OBJECTIVES: Recent studies have shown a high prevalence of hypovitaminosis D, defined as a serum 25-hydroxyvitamin D level less than 30 ng/ml, in both healthy populations and patients with chronic kidney disease. Patients undergoing kidney transplant are at an increased risk of skin cancer and are advised to avoid sunlight exposure. Therefore, these patients might share two major risk factors for hypovitaminosis D: chronic kidney disease and low sunlight exposure. This paper describes the prevalence and clinical characteristics of hypovitaminosis D among patients undergoing kidney transplant. METHODS: We evaluated 25-hydroxyvitamin D serum levels in a representative sample of patients undergoing kidney transplant. We sought to determine the prevalence of hypovitaminosis D, compare these patients with a control group, and identify factors associated with hypovitaminosis D (e.g., sunlight exposure and dietary habits. RESULTS: Hypovitaminosis D was found in 79% of patients undergoing kidney transplant, and the major associated factor was low sunlight exposure. These patients had higher creatinine and intact parathyroid hormone serum levels, with 25-hydroxyvitamin D being inversely correlated with intact parathyroid hormone serum levels. Compared with the control group, patients undergoing kidney transplant presented a higher prevalence of 25-hydroxyvitamin D deficiency and lower serum calcium, phosphate and albumin but higher creatinine and intact parathyroid hormone levels. CONCLUSIONS: Our results confirmed the high prevalence of hypovitaminosis D in patients undergoing kidney transplant. Therapeutic strategies such as moderate sunlight exposure and vitamin D supplementation should be seriously considered for this population.

Endoscopic retrograde cholangiopancreatography (ERCP) is associated with an acute inflammatory response and melatonin has a variety of immunomodulatory and antioxidant effects studied experimentally in pancreatobiliary pathology. The aim of our study was to evaluate the effects of peri-procedural administration of melatonin on the inflammatory response and lipid peroxidation associated with ERCP. In this proof-of-concept clinical trial, 37 patients with a high probability of choledocholithiasis were randomized to receive peri-procedure (ERCP) melatonin or placebo. We measured the serum concentration of tumor necrosis factor-alpha (TNF-alpha), interleukin-6 (IL-6), vascular endothelial growth factor (VEGF), lipid peroxidation, amylase, and liver function tests 24h before and after the procedure. We found no pre-procedure or post-procedure differences between the melatonin group or the placebo group (P>.05) in the serum concentrations of TNF-alpha (melatonin: 153.8 vs. 149.4ng/m; placebo: 103.5 vs. 107.3ng/ml), IL-6 (melatonin: 131.8 vs. 133.3ng/ml; placebo: 177.8 vs. 197.8ng/ml), or VEGF (melatonin: 157.3 vs. 157.8pg/ml; placebo: 97.3 vs. 97.8pg/ml), or in relation to lipid peroxidation (melatonin: 39.2 vs. 72.3μg/ml; placebo: 66.4 vs. 90.5μg/ml). After ERCP, a significant decrease in the AST, ALT, and total bilirubin levels was found only in the melatonin group (P<.05). The administration of melatonin was safe and tolerable. Melatonin is safe and tolerable in patients undergoing ERCP, but it does not appear to affect inflammatory cytokine concentrations or lipid peroxidation.

As finite healthcare resources come under pressure, the value of physician activity is assuming increasing importance. The value in healthcare can be defined as patient health outcomes achieved per monetary unit spent. Even though some attempts have been made to quantify the value of clinician activity, there is little in the medical literature describing the importance of endoscopists' activity. This study aimed to characterize the value of endoscopic retrograde cholangiopancreatography (ERCP) performance of five gastroenterologists. We carried out a retrospective-prospective cohort study using the databases of patients undergoing ERCP between September 2014 and March 2017. We collected data from 1070 patients who underwent ERCP comparing value among the ERCPists at index ERCP. Procedure value was calculated using the formula Q/(T/C), where Q is the quality of procedure, T is the duration of procedure and C is the adjusted for complexity level. Quality and complexity were derived on a 1-4 Likert scale on the basis of American Society for Gastrointestinal Endoscopy criteria; time was recorded (in min) from intubation to extubation. Endoscopist time calculated from procedure time was considered a surrogate marker of cost as individual components of procedure cost were not itemized. In total, 590 procedures were analysed: 465 retrospectively over 24 months and 125 prospectively over 6 months. There was a 32% variation in the value of endoscopist activity in a more substantial retrospective cohort, with an even more considerable 73% variation in a smaller prospective arm. In an analysis of greater than 1000 ERCPs by a small cohort of experienced ERCPists, there was a wide variation in the value of endoscopist activity. Although the precision of estimating procedural costs needs further refinement, these findings show the ability to stratify ERCPists on the basis of the value their activity. As healthcare costs are scrutinized more closely, such value measurements are

Patients undergoing lobectomy are at significantly increased risk of lung injury. One-lung ventilation is the most commonly used technique to maintain ventilation and oxygenation during the operation. It is a challenge to choose an appropriate mechanical ventilation strategy to minimize the lung injury and other adverse clinical outcomes. In order to understand the available evidence, a systematic review was conducted including the following topics: (I) protective ventilation (PV); (II) mode of mechanical ventilation [e.g., volume controlled (VCV) versus pressure controlled (PCV)]; (III) use of therapeutic hypercapnia; (IV) use of alveolar recruitment (open-lung) strategy; (V) pre-and post-operative application of positive end expiratory pressure (PEEP); (VI) Inspired Oxygen concentration; (VII) Non-intubated thoracoscopic lobectomy; and (VIII) adjuvant pharmacologic options. The recommendations of class II are non-intubated thoracoscopic lobectomy may be an alternative to conventional one-lung ventilation in selected patients. The recommendations of class IIa are: (I) Therapeutic hypercapnia to maintain a partial pressure of carbon dioxide at 50–70 mmHg is reasonable for patients undergoing pulmonary lobectomy with one-lung ventilation; (II) PV with a tidal volume of 6 mL/kg and PEEP of 5 cmH2O are reasonable methods, based on current evidence; (III) alveolar recruitment [open lung ventilation (OLV)] may be beneficial in patients undergoing lobectomy with one-lung ventilation; (IV) PCV is recommended over VCV for patients undergoing lung resection; (V) pre- and post-operative CPAP can improve short-term oxygenation in patients undergoing lobectomy with one-lung ventilation; (VI) controlled mechanical ventilation with I:E ratio of 1:1 is reasonable in patients undergoing one-lung ventilation; (VII) use of lowest inspired oxygen concentration to maintain satisfactory arterial oxygen saturation is reasonable based on physiologic principles; (VIII) Adjuvant drugs

Full Text Available Abstract Most Spanish prisons provide specialised treatment for incarcerated sex offenders, both rapists and child molesters. This treatment is a cognitive-behavioural intervention that has shown relative effectiveness in previous research. With regard to offenders’ rehabilitation, recidivism assessments are necessary as a final measure of treatment effectiveness. However, the evaluation of recidivism by itself does not provide sufficient information on the treatment process and the specific effects that treated subjects could undergo. This paper aims to analyse the therapeutic effectiveness of psychological treatment provided to rapists (in general, males sentenced for committing a sexual offence against women. To this aim, a group of treated rapists (N=153 serving a sentence in prison was analysed. Using a specially designed scale (PASSO, the global therapeutic change and ten specific variables (including assertiveness, readiness to change, cognitive distortions, impulsivity, etc. were assessed. The within-subjects comparison showed that treated sex offenders improved, in therapeutic terms, globally as well as in most of the specific variables assessed (improvements not experimented by the control group. Also, different therapeutic subscales showed relevant associations between them. The findings regarding treatment effectiveness are discussed.

The role of the radiologist in evaluating the jaundiced patient has changed dramatically during the past 5 years. Before this period, conventional radiographic evaluation of the bile duct has been by indirect methods (upper gastrointestinal (UGI) examinations, hypertonic duodenography, arteriography or rather limited direct methods, such as intravenous cholangiography. These methods have largely been replaced by diagnostic noninvasive cross-sectional modalities, ultrasound and computed tomography (CT), and therapeutic invasive modalities such as percutaneous transhepatic cholangiography (PTC) and endoscopic retrograde cholangiography (ERCP). Although many articles in the literature have outlined the individual merits of these modalities, little attempt has been made to integrate and compare these diverse diagnostic and therapeutic tests. Before analyzing the various approaches to jaundice, it is important to determine the end point in studying these patients. For example, several articles in the medical literature state that a well-versed clinician can differentiate obstructive from nonobstructive jaundice on the basis of history, physical examination, and liver function tests, 75-80% of the time. Consequently an argument could be made that a jaundiced patient be examined, undergo a few laboratory tests, and be treated either medically or surgically with no further tests. Several points, however, dictate against this approach

Full Text Available Objective. Out of hospital cardiac arrest (OHCA patients are a critically ill patient population with high mortality. Combining mild therapeutic hypothermia (MTH with early coronary intervention may improve outcomes in this population. The aim of this study was to evaluate predictors of mortality in OHCA patients undergoing MTH with and without cardiac catheterization. Design. A retrospective cohort of OHCA patients who underwent MTH with catheterization (MTH + C and without catheterization (MTH + NC between 2006 and 2011 was analyzed at a single tertiary care centre. Predictors of in-hospital mortality and neurologic outcome were determined. Results. The study population included 176 patients who underwent MTH for OHCA. A total of 66 patients underwent cardiac catheterization (MTH + C and 110 patients did not undergo cardiac catheterization (MTH + NC. Immediate bystander CPR occurred in approximately half of the total population. In the MTH + C and MTH + NC groups, the in-hospital mortality was 48% and 78%, respectively. The only independent predictor of in-hospital mortality for patients with MTH + C, after multivariate analysis, was baseline renal insufficiency (OR = 8.2, 95% CI 1.8–47.1, and p = 0.009. Conclusion. Despite early cardiac catheterization, renal insufficiency and the absence of immediate CPR are potent predictors of death and poor neurologic outcome in patients with OHCA.

Objective Single-stage endoscopic stone removal for choledocholithiasis is an advantageous approach because it is associated with a shorter hospital stay; however, few studies have reported the incidence of complications related to this procedure in detail. The aim of this study was to examine the incidence of complications and efficacy of this procedure. Methods This retrospective study investigated the incidence of complications in 345 patients with naive papilla who underwent therapeutic endoscopic retrograde cholangiopancreatography (ERCP) for choledocholithiasis at three institutions between April 2014 and March 2016 by a propensity score analysis. The efficacy of single-stage endoscopic stone removal was assessed based on a hospital stay of within 7 days and the number of ERCP attempts. Results Among 114 patients who underwent single-stage endoscopic stone removal, 15 patients (13.2%) experienced complications. Among the remaining 231 patients in the two-stage endoscopic stone removal group, complications were observed in 17 patients (7.4%). The propensity score analysis, which was adjusted for confounding factors, revealed that single-stage endoscopic stone removal was not a significant risk factor for complications (p=0.52). In patients in whom >10 min was required for deep cannulation, single-stage endoscopic stone removal was not a significant risk factor for complications in the propensity score analysis (p=0.37). In the single-stage group, the proportion of patients with a hospital stay of within 7 days was significantly higher and the number of ERCP attempts was significantly lower in comparison to the two-stage group (p <0.0001 and <0.0001, respectively). Conclusion Single-stage endoscopic stone removal did not increase the incidence of complications associated with ERCP and was effective for reducing the hospital stay and the number of ERCP attempts.

According to the current literature, biliary lithiasis is a worldwide-diffused condition that affects almost 20% of the general population. The rate of common bile duct stones (CBDS) in patients with symptomatic cholelithiasis is estimated to be 10% to 33%, depending on patient's age. Compared to stones in the gallbladder, the natural history of secondary CBDS is still not completely understood. It is not clear whether an asymptomatic choledocholithiasis requires treatment or not. For many years, open cholecystectomy with choledochotomy and/or surgical sphincterotomy and cleaning of the bile duct were the gold standard to treat both pathologies. Development of both endoscopic retrograde cholangiopancreatography (ERCP) and laparoscopic surgery, together with improvements in diagnostic procedures, influenced new approaches to the management of CBDS in association with gallstones. We decided to systematically review the literature in order to identify all the current therapeutic options for CBDS. A systematic literature search was performed independently by two authors using PubMed, EMBASE, Scopus and the Cochrane Library Central. The therapeutic approach nowadays varies greatly according to the availability of experience and expertise in each center, and includes open or laparoscopic common bile duct exploration, various combinations of laparoscopic cholecystectomy and ERCP and combined laparoendoscopic rendezvous. Although ERCP followed by laparoscopic cholecystectomy is currently preferred in the majority of hospitals worldwide, the optimal treatment for concomitant gallstones and CBDS is still under debate, and greatly varies among different centers.

To investigate the effects of Therapeutic Touch (TT) on anxiety, vital signs, and cardiac dysrhythmia in women undergoing cardiac catheterization. It was a quasi-experimental study. The participants had no history of hallucination, anxiety, or other psychological problems. Participants had to be conscious and have attained at least sixth-grade literacy level. Participants were randomly assigned into an intervention group (n = 23; received 10-15 minutes TT), a placebo group (n = 23; received 10-15 minutes simulated touch), and a control group (n = 23; did not receive any therapy). Data were collected using Spielberger's anxiety test, cardiac dysrhythmia checklist, and vital signs recording sheet. Statistical analyses were considered to be significant at α = .05 levels. Sixty-nine women ranging in age from 35 to 65 years participated. TT significantly decreased state anxiety p < 0.0001 but not trait anxiety (p = .88), decreased the incidence of all cardiac dysrhythmias p < 0.0001 except premature ventricular contraction (p = .01), and regulated vital signs p < 0.0001 in the intervention group versus placebo and control group. TT is an effective approach for managing state anxiety, regulating vital signs, and decreasing the incidence of cardiac dysrhythmia during stressful situations, such as cardiac catheterization, in Iranian cardiac patients.

Diagnosis and management of pancreaticopleural fistula.

Science.gov (United States)

Tay, Clifton Ming; Chang, Stephen Kin Yong

2013-04-01

Pancreaticopleural fistula is a rare diagnosis requiring a high index of clinical suspicion due to the predominant manifestation of thoracic symptoms. The current literature suggests that confirmation of elevated pleural fluid amylase is the most important diagnostic test. Magnetic resonance cholangiopancreatography is the recommended imaging modality to visualise the fistula, as it is superior to both computed tomography and endoscopic retrograde cholangiopancreatography (ERCP) in delineating the tract within the pancreatic region. It is also less invasive than ERCP. While a trial of medical regimen has traditionally been the first-line treatment, failure would result in higher rates of complications. Hence, it is suggested that management strategies be planned based on pancreatic ductal imaging, with patients having poor chances of spontaneous closure undergoing either endoscopic or surgical intervention. We also briefly describe a case of pancreaticopleural fistula in a patient who was treated using a modified Puestow procedure after failed endoscopic treatment.

Full Text Available Aims and hypothesisHypoxic-ischemic encephalopathy (HIE remains an important cause of death and disability in newborns. Mild therapeutic hypothermia (TH is safe and effective; however, there are no tissue biomarkers available at the bedside to select babies for treatment. The aim of this study was to show that it is feasible to study plasma neurofilament light (NfL levels from newborns and to evaluate their temporal course. Hypothesis: Raised plasma NFL protein levels from newborns who undergo TH after HIE are associated with abnormal MRI outcomes.MethodsBetween February 2014 and January 2016, term newborns with HIE treated with TH for 72 h had plasma samples taken at three time points: (i after the infant had reached target temperature, (ii prior to commencing rewarming, and (iii after completing rewarming. Infants with mild HIE who did not receive TH had a single specimen taken. NfL protein was analyzed using an enzyme-linked immunosorbent assay.ResultsTwenty-six newborns with moderate–severe HIE treated with TH were studied. Half of these had cerebral MRI predictive of an unfavorable outcome.

There is a growing population of women who have or will undergo hematopoietic stem cell transplant for a variety of malignant and benign conditions. Gynecologists play an important role in addressing the gynecologic and reproductive health concerns for these women throughout the transplant process. As women undergo cell transplantation, they should avoid becoming pregnant and are at risk of uterine bleeding. Thus, counseling about and implementing hormonal treatments such as gonadotropin-releasing hormone agonists, combined hormonal contraceptives, and progestin-only methods help to achieve therapeutic amenorrhea and can serve as contraception during the peritransplant period. In this commentary, we summarize the timing, risks and benefits of the hormonal options just prior, during and for the year after hematopoietic stem cell transplantation. PMID:26348182

AIM To compare the efficacy of a session of extracorporeal shock wave lithotripsy (ESWL) before endoscopic retrograde cholangiopancreatography (ERCP) vs ERCP only for problematic and large common bile duct (CBD) stones. METHODS Adult patients with CBD stones for whom initial ERCP was unsuccessful because of the large size of CBD stones were identified. The patients were randomized into two groups, an “ESWL + ERCP group” and an “ERCP-only” group. For ESWL + ERCP cases, ESWL was performed prior to ERCP. Clearance of the CBD, complications related to the ESWL/ERCP procedure, frequency of mechanical lithotripsy use and duration of the ERCP procedure were evaluated in both groups. RESULTS There was no significant difference in baseline characteristics between the two groups. A session of ESWL before ERCP compared with ERCP only resulted in similar outcomes in terms of successful stone removal within the first treatment session (74.2% vs 71.0%, P = 0.135), but a higher clearance rate within the second treatment session (84.4% vs 51.6%, P = 0.018) and total stone clearance (96.0% vs 86.0%, P = 0.029). Moreover, ESWL prior to ERCP not only reduced ERCP procedure time (43 ± 21 min vs 59 ± 28 min, P = 0.034) and the rate of mechanical lithotripsy use (20% vs 30%, P = 0.025), but also raised the clearance rate of extremely large stones (80.0% vs 40.0%, P = 0.016). Post-ERCP complications were similar for the two groups. CONCLUSION Based on the higher rate of successful stone removal and minimal complications, ESWL prior to ERCP appears to be a safe and effective treatment for the endoscopic removal of problematic and large CBD stones.

To evaluate the frequency and contributing factors for acute pancreatitis after endoscopic retrograde cholangio-pancreatography in patients with obstructive jaundice. Study Design: Descriptive case series. Place and Duration of Study: A descriptive case series conducted at department of Gastroenterology, Shaikh Zayed Hospital, Lahore in the period of six months. Material and Methods: Two hundred and thirty patients diagnosed as having obstructive jaundice and undergoing ERCP who fulfilled the inclusion criteria were included in the study from the outpatient and indoor department of Gastroenterology-Hepatology Shaikh Zayed Hospital Lahore. Informed consent was taken. After the selection of the cases, patients were evaluated for the presence or absence of contributing factors like age, gender, cannulation attempts, cannulation time, percutaneous papillotomy, pancreatic duct contrast injection and previous history of post ERCP pancreatitis. Data was analysed by using the statistical software for social sciences (SPSS) version 15. Results: In our study, mean age was 44 +- 14.12 years. Out of 230 patients 42.17% (n=97) were male and 57.83% (n=133) were females. Frequency of acute pancreatitis after ERCP in patients with obstructive jaundice was 4.78% (n=11) while 95.22% (n=219) had no findings of acute pancreatitis after ERCP. Frequency of factors for acute pancreatitis after endoscopic retrograde cholangiopancreatography in patients with obstructive jaundice was recorded which shows that out of 11 cases, 45.45% (n=5) were females, 36.36% (n=4) had previous history of Post ERCP Pancreatitis, 27.27% (n=3) had >5 attempts of cannulation, 36.36% (n=4) had >5 minute time for cannulation, 54.55% (n=6) had pre-cut papillotomy while 63.64% (n=7) had pancreatic duct contrast injection. Conclusion: We concluded that frequency of acute pancreatitis after endoscopic retrograde cholangiopancreatography in patients with obstructive jaundice was found not very high in our practice

Phenobarbital is the first-line treatment for neonatal seizures. Many neonates with hypoxic ischemic encephalopathy are treated with therapeutic hypothermia, and about 40% have clinical seizures. Little is known about the pharmacokinetics of phenobarbital in infants with hypoxic ischemic encephalopathy who undergo therapeutic hypothermia. The objective of this study was to determine the effect of therapeutic hypothermia on phenobarbital pharmacokinetics, taking into account maturational changes. Level 3 neonatal ICU. Infants with hypoxic ischemic encephalopathy and suspected seizures, all treated with phenobarbital. Some of these infants also received treatment with therapeutic hypothermia. None. A retrospective cohort study of 39 infants with hypoxic ischemic encephalopathy treated with phenobarbital (20 were treated with therapeutic hypothermia and 19 were not). Data on phenobarbital plasma concentrations were collected in 39 subjects with hypoxic ischemic encephalopathy with or without therapeutic hypothermia. Using nonlinear mixed-effects modeling, population pharmacokinetics of phenobarbital were developed with a total of 164 plasma concentrations. A one-compartment model best described the pharmacokinetics. The clearance of phenobarbital was linearly related to body weight and matured with increasing age with a maturation half-life of 22.1 days. Therapeutic hypothermia did not influence the pharmacokinetic parameters of phenobarbital. Therapeutic hypothermia does not influence the clearance of phenobarbital after accounting for weight and age. Standard phenobarbital dosing is appropriate for the initial treatment of seizures in neonates with hypoxic ischemic encephalopathy treated with therapeutic hypothermia.

Therapeutic antibodies have captured substantial attention due to the relatively high rate at which these products reach marketing approval, and the subsequent commercial success they frequently achieve. In the 2000s, a total of 20 antibodies (18 full-length IgG and 2 Fab) were approved by the Food and Drug Administration (FDA) or European Medicines Agency (EMA). In the 2010s to date, an additional 3 antibodies (denosumab, belimumab, ipilimumab) have been approved and one antibody-drug conjugate (brentuximab vedotin) is undergoing regulatory review and may be approved in the US by August 30, 2011. However, a less heralded group of antibody-based therapeutics comprising proteins or peptides fused with an Fc is following the success of classical antibodies.

Current status of laparoendoscopic rendezvous in the treatment of cholelithiasis with concomitant choledocholithiasis.

Science.gov (United States)

Baloyiannis, Ioannis; Tzovaras, George

2015-06-25

The current evidence in favor of the laparoendoscopic rendezvous is promising and demonstrates the main advantages of this technique in regard to shorter hospital stay and selective cannulation of the common bile duct (CBD), avoiding thus the inadvertent cannulation of the pancreatic duct. In addition, in the rendezvous technique the contrast medium is not injected retrogradely as during the traditional endoscopic retrograde cholangiopancreatography (ERCP), when the medium accidentally could be injected under pressure into the pancreatic duct. The RV technique minimizes that risk. Both these main advantages of the RV technique over the classic ERCP, are related with a significant lower incidence of hyperamylasemia and post-ERCP pancreatitis, compared with the traditional two stage procedure. Choledocholithiasis is present in 10% to 15% of patients undergoing cholecystectomy. To date, the ideal management of CBD stones remains controversial. Prospective randomized trials have shown that laparoscopic management of the CBD stones, as a single stage procedure, is the most efficient and cost effective method of treatment. Laparoendoscopic rendezvous has been proposed as an alternative single stage approach. Several studies have shown the effective use of this technique in the treatment of CBD stones by improving patient compliance and clinical results including shorter hospital stay, higher success rate and less cost. The current evidence about the use of this technique presented in this review article is promising and demonstrates the main advantages of the procedure.

Pancreatic extracorporeal shock wave lithotripsy (P-ESWL) is the first-line therapy for large pancreatic duct stones. Although it is a highly effective and safe procedure for the fragmentation of pancreatic stones, it is still not complication-free. Just like endoscopic retrograde cholangiopancreatography (ERCP), pancreatitis is the most common complication. To date, nonsteroidal anti-inflammatory drugs (NSAIDs) have proven to be the only effective prophylactic medication for post-ERCP pancreatitis and the European, American and Japanese Society for Gastrointestinal Endoscopy guidelines have recommended prophylactic rectally administered indomethacin for all patients undergoing ERCP. Given the little research about effective prevention for post P-ESWL pancreatitis, we aim to determine whether rectally administered indomethacin can reduce post-ESWL-pancreatitis. The RIPEP study is a prospective, randomized, double-blinded, placebo-controlled trial. One thousand three hundred and seventy patients with chronic pancreatitis and pancreatic stones (>5 mm in diameter) treated with P-ESWL at Changhai Hospital will be randomly allocated to rectally administered indomethacin or placebo therapy before the procedure. The primary endpoint is the incidence of post-ESWL pancreatitis. Secondary endpoints include the severity of pancreatitis, occurrence rate of asymptomatic hyperamylasemia and other complications. The RIPEP trial is designed to show that rectally administered indomethacin reduces the development and severity of post-ESWL pancreatitis and benefits patients treated with P-ESWL.

Rendezvous intraoperative endoscopic retrograde cholangiography (RV-IOERC), also called guidewire-facilitated IOERC, is one of the single-stage options available for managing common bile duct stones (CBDS) during laparoscopic cholecystectomy. The objective of this study is to investigate procedure-related complications in IOERC patients and stone clearance. All patients who underwent IOERC between January 2000 and December 2009 were identified from the local registry of Karolinska University Hospital in Huddinge. Medical charts and ERC reports were studied, and descriptive statistics were obtained. Outcomes were procedure-related complications, especially post-ERCP pancreatitis (PEP), stone clearance, and mortality. 307 patients were identified. In 264 of the patients, the rendezvous cannulation technique was successful (86 %); in the remaining 43 patients, conventional cannulation technique was necessary. In total, PEP occurred in seven patients (2.28 %). One of the PEP patients was in the rendezvous cannulated group (0.37 %), whereas six patients developed PEP in the nonrendezvous group (13.95 %, p < 0.001). The primary stone clearance rate was 88.27 % (271/307). There was no mortality within 90 days in the series. IOERC with RV cannulation technique for management of CBDS during laparoscopic cholecystectomy has a low PEP rate and a high stone clearance rate, making it a safe and feasible method for removing CBDS. However, the technique requires logistics to perform IOERC in the operating theater. The present data suggest that IOERC with RV cannulation is superior to conventional cannulation with respect to risk of PEP.

Full Text Available ObjectiveTo retrospectively evaluate the therapeutic efficacy and safety of endoscopic retrograde cholangiopancreatography (ERCP for treating acute cholecystitis in geriatric patients 75 years and older in age. MethodsThe clinical records of our institute were searched to identify aged (75-84 years old and elderly (85 years and older patients who underwent ERCP between January 2008 and December 2012 for new or long-term cholecystitis. The cholecystitis was clinically characterized as acute attack time(s of one to five days and diagnosis was confirmed by imaging analysis (including abdominal ultrasound, computed tomography, and/or magnetic resonance cholangiopancreatography. All surgeries were carried out with the endoscopic nasogallbladder drainage (ENGBD procedure. Postoperative symptoms (such as abdominal pain and fever and clinical findings (such as C-reactive protein (CRP level, imaging findings, and bile drainage volume and consistency were recorded, along with follow-up data of outcome and symptomology, for summary evaluation. ResultsA total 24 patients, including 13 men and 11 women between the ages of 75 and 88 (mean: 81.00±3.23 years, underwent ERCP examination. The cases included general cholecystitis (75.0%, n=18 and acalculous cholecystitis (25.0%, n=6. In addition, 13 (54.2% cases had biliary stones and two (8.3% cases had bile pancreatitis. The ENGBD tube was successfully inserted into the gallbladder in all cases. Twenty-one (87.5% patients experienced relief of abdominal pain and fever within 24 h of the surgery. CRP level decreased to normal for all (100% patients within six days of the surgery. Two (8.3% patients experienced hyperamylasemia within three days of the surgery, and both cases resolved prior to hospital release.

Although endoscopic retrograde cholangiopancreatography (ERCP) is an effective modality for diagnosis and treatment of biliary and pancreatic diseases, the risk for procedure-related complications is high. Hemorrhage is one of major complications of ERCP. Most ERCP-associated bleeding is primarily a complication related to sphincterotomy rather than diagnostic ERCP. We are reporting a case of massive hemobilia due to hepatic arteriobiliary fistula caused by guidewire-associated injury during ERCP, which was successfully treated with transarterial embolization of the hepatic artery.

The endogenous genital flora is a major source of infections of the female genital tract, especially in patients with cervical or endometrial cancer. Until recently the 'radiosterilisation of the vagina', respectively a prophylactic and/or therapeutic effect of irradiation (external highvoltage as well as intracavitary-radium) concerning infections was postulated in the literature. This theory was disproved in a prospective clinical and bacteriological study covering 48 patients with advanced cervical cancer undergoing primary intracavitary radium-irradiation and 38 patients with inoperable endometrical cancer, undergoing primary iridium-192-afterloading. Following intracavitary radium for cervical cancer some typical nosocomial pathogens like Streptococcus faecalis, Enterobacter, Klebsiella, Proteus and Pseudomonas were isolated significantly more frequently than before treatment. Likewise, the mean number of aerobic bacterial species increased significantly after irradiation. Also primary Ir-192 (afterloading) irradiation did not alter the frequency of isolation of the resident flora in endometrial cancer patients. Therefore, 'radiosterilisation' of the vagina as result of radiotherapy does not exist. (orig.) [de

Highlights: • Therapeutic targeting or inhibition of the key molecules of signaling pathways can control growth of breast cancer stem cells (BCSCs). • Development of BCSCs also involves miRNA interactions. • Therapeutic achievement can be done by targeting identified targets in the BCSC pathways. - Abstract: A small heterogeneous population of breast cancer cells acts as seeds to induce new tumor growth. These seeds or breast cancer stem cells (BCSCs) exhibit great phenotypical plasticity which allows them to undergo “epithelial to mesenchymal transition” (EMT) at the site of primary tumor and a future reverse transition. Apart from metastasis they are also responsible for maintaining the tumor and conferring it with drug and radiation resistance and a tendency for post-treatment relapse. Many of the signaling pathways involved in induction of EMT are involved in CSC generation and regulation. Here we are briefly reviewing the mechanism of TGF-β, Wnt, Notch, TNF-α, NF-κB, RTK signalling pathways which are involved in EMT as well as BCSCs maintenance. Therapeutic targeting or inhibition of the key/accessory players of these pathways could control growth of BCSCs and hence malignant cancer. Additionally several miRNAs are dysregulated in cancer stem cells indicating their roles as oncogenes or tumor suppressors. This review also lists the miRNA interactions identified in BCSCs and discusses on some newly identified targets in the BCSC regulatory pathways like SHIP2, nicastrin, Pin 1, IGF-1R, pro-inflammatory cytokines and syndecan which can be targeted for therapeutic achievements.

To examine whether rendezvous endoscopic retrograde cholangiopancreatography (ERCP) is associated with less pancreatic damage, measured as leakage of proenzymes, than conventional ERCP. Patients (n = 122) with symptomatic gallstone disease, intact papilla and no ongoing inflammation, were prospectively enrolled in this case-control designed study. Eighty-one patients were subjected to laparoscopic cholecystectomy and if intraoperative cholangiography suggested common bile duct stones (CBDS), rendezvous ERCP was performed intraoperatively (n = 40). Patients with a negative cholangiogram constituted the control group (n = 41). Another 41 patients with CBDS, not subjected to surgery, underwent conventional ERCP. Pancreatic proenzymes, procarboxypeptidase B and trypsinogen-2 levels in plasma, were analysed at 0, 4, 8 and 24 h. The proenzymes were determined in-house with a double-antibody enzyme linked immunosorbent assay. Pancreatic amylase was measured by an enzymatic colourimetric modular analyser with the manufacturer's reagents. All samples were blinded at analysis. Post ERCP pancreatitis (PEP) occurred in 3/41 (7%) of the patients cannulated with conventional ERCP and none in the rendezvous group. Increased serum levels indicating pancreatic leakage were significantly higher in the conventional ERCP group compared with the rendezvous ERCP group regarding pancreatic amylase levels in the 4- and 8-h samples (P = 0.0015; P = 0.03), procarboxypeptidase B in the 4- and 8-h samples (P rendezvous cannulation technique compared with patients that underwent cholecystectomy alone (control group). Post procedural concentrations of pancreatic amylase and procarboxypeptidase B were significantly correlated with pancreatic duct cannulation and opacification. Rendezvous ERCP reduces pancreatic enzyme leakage compared with conventional ERCP cannulation technique. Thus, laparo-endoscopic technique can be recommended with the ambition to minimise the risk for post ERCP

Post-ERCP pancreatogastric fistula associated with an intraductal papillary-mucinous neoplasm of the pancreas – a case report and literature review

Full Text Available Abstract Background Fistula formation has been reported in intraductal papillary-mucinous neoplasms (IPMNs with or without invasion of the adjacent organs. The presence or absence of invasion is mostly determined by postoperative histological examination rather than by preoperative work-up. Case presentation A 72 year-old Japanese woman showed remarkable dilatation of the main pancreatic duct (MPD in the distal region of the pancreas. Subsequent ERCP also showed MPD dilatation, after which the patient suffered moderate pancreatitis. A subsequent gastroscopy revealed a small ulceration that had not been observed in a gastroscopy performed 3 months prior. Mucinous discharge from the ulceration suggested it might be the orifice of a fistula connected to the MPD. En bloc resection including the distal region of the pancreas, spleen, stomach and part of the transverse colon was performed under the pre- and intraoperative diagnosis of an invasive malignant IPMN. However, histopathology revealed the lesion to be of "borderline malignancy" without apparent invasion of the stomach. Light microscopy showed inflammatory cellular infiltrates (mainly neutrophils around the pancreatogastric fistula, but there was no evidence of neoplastic epithelia lining the fistulous tract. Conclusion This case highlights that a pancreatogastric fistula can develop after acute inflammation of the pancreas in the absence of cancer invasion. Further information regarding IPMN-associated fistulae is necessary to clarify the pathogenesis, diagnosis, appropriate surgical intervention and prognosis for this disorder.

Full Text Available Following optic nerve injury associated with acute or progressive diseases, retinal ganglion cells (RGCs of adult mammals degenerate and undergo apoptosis. These diseases have limited therapeutic options, due to the low inherent capacity of RGCs to regenerate and due to the inhibitory milieu of the central nervous system. Among the numerous treatment approaches investigated to stimulate neuronal survival and axonal extension, cell transplantation emerges as a promising option. This review focuses on cell therapies with bone marrow mononuclear cells and bone marrow-derived mesenchymal stem cells, which have shown positive therapeutic effects in animal models of optic neuropathies. Different aspects of available preclinical studies are analyzed, including cell distribution, potential doses, routes of administration, and mechanisms of action. Finally, published and ongoing clinical trials are summarized.

Full Text Available Prognostic evaluation of patients with primary biliary cirrhosis (PBC and how to improve the prognosis have attracted much attention. Further therapeutic regimens for PBC patients with poor prognosis has become the direction of clinical and scientific studies. This article summarizes the association between baseline indices and prognosis and prognostic evaluation of patients undergoing ursodeoxycholic acid (UDCA treatment, introduces the current status of UDCA combined with budesonide, fibrates, and obeticholic acid for patients with poor response to UDCA and the drugs being developed, and analyzes the influencing factors for prognosis and efficacy of UDCA. It is pointed out that prognosis and efficacy should be evaluated before and during UDCA treatment, and that therapeutic regimens should be adjusted in time to improve prognosis.

To determine the relationship between left ventricular cardiac output (LVCO), superior vena cava (SVC) flow, and brain injury during whole-body therapeutic hypothermia. Sixteen newborns with moderate or severe hypoxic-ischemic encephalopathy were studied using echocardiography during and immediately after therapeutic hypothermia. Measures were also compared with 12 healthy newborns of similar postnatal age. Newborns undergoing therapeutic hypothermia also had cerebral magnetic resonance imaging as part of routine clinical care on postnatal day 3-4. LVCO was markedly reduced (mean ± SD 126 ± 38 mL/kg/min) during therapeutic hypothermia, whereas SVC flow was maintained within expected normal values (88 ± 27 mL/kg/min) such that SVC flow represented 70% of the LVCO. The reduction in LVCO during therapeutic hypothermia was mainly accounted by a reduction in heart rate (99 ± 13 vs 123 ± 17 beats/min; P newborns without brain injury (P = .013). Newborns with perinatal hypoxic-ischemic encephalopathy showed a preferential systemic-to-cerebral redistribution of cardiac blood flow during whole-body therapeutic hypothermia, which may reflect a lack of cerebral vascular adaptation in newborns with more severe brain injury.

This study aimed to compare 50 mg dexketoprofen vs. 1 g paracetamol that were parenterally administered before endoscopic retrograde cholangiopancreatography (ERCP) under sedoanalgesia with comparable anaesthesia depth regarding haemodynamic, pain, narcotic analgesic requirement, recovery and post-procedural cognitive functions. Overall, 80 ASA I-III patients aged 18-75 years who were undergoing scheduled ERCP were randomly assigned into three groups. In all patients, the mini-mental test (MMT) was conducted before the procedure. No drug was administered to controls (Group C; n=26); patients were transferred to ERCP unite 30 min after parenteral dexketoprofen (50 mg) in group D (n=27) and paracetamol (1 g) in group P (n=27). The standard monitoring was applied. After intravenously administering loading doses of midazolam (0.02 mgkg) and propofol (1 mg kg(-1)), propofol infusion was administered at a dose of 2-4 mg kg(-1) h(-1) to maintain a bispectral index value of 50-70. Fentanyl (0.05 μg kg(-1)) was intravenously administered when patients experienced pain. Haemodynamic effects, additional analgesic requirement, adverse effects during procedure, time to reach Aldrete score of 9 and satisfaction of an endoscopist and patient were recorded. MMT was repeated 3 h after completing the procedure. Fentanyl requirement during the procedure was significantly low in group D (pdexketoprofen provided better haemodynamic effect and pain control, thereby decreasing incidence of adverse events by reducing the requirement for narcotic analgesics.

Carbapenem-resistant Klebsiella pneumoniae infections are increasingly prevalent in North American hospitals. We describe an outbreak of carbapenem-resistant K. pneumoniae containing the blaOXA-232 gene transmitted by contaminated duodenoscopes during endoscopic retrograde cholangiopancreatography (ERCP) procedures. An outbreak investigation was performed when 9 patients with blaOXA-232 carbapenem-resistant K. pneumoniae infections were identified at a tertiary care hospital. The investigation included 2 case-control studies, review of duodenoscope reprocessing procedures, and culture of devices. Carbapenem-resistant Enterobacteriacieae (CRE) isolates were evaluated with polymerase chain reaction analysis for carbapenemase genes, and isolates with the blaOXA-232 gene were subjected to whole-genome sequencing and chromosome single-nucleotide polymorphism analysis. On recognition of ERCP as a key risk factor for infection, targeted patient notification and CRE screening cultures were performed. Molecular testing ultimately identified 17 patients with blaOxa-232 carbapenem-resistant K. pneumoniae isolates, including 9 with infections, 7 asymptomatic carriers who had undergone ERCP, and 1 additional patient who had been hospitalized in India and was probably the initial carrier. Two case-control studies established a point-source outbreak associated with 2 specific duodenoscopes. A field investigation of the use, reprocessing, and storage of deuodenoscopes did not identify deviations from US Food and Drug Administration or manufacturer recommendations for reprocessing. This outbreak demonstrated the previously underappreciated potential for duodenoscopes to transmit disease, even after undergoing high-level disinfection according to manufacturers' guidelines.

Full Text Available Objective: To analyze the differences in intraoperative conditions and postoperative inflammatory response and immune response levels in patients with common bile duct stones undergoing ESBD and EST treatment. Methods: A total of 565 patients with common bile duct stones who underwent ERCP treatment in our hospital from January 2013 to December 2015 were included in the study, patients’ treatment and testing results were analyzed retrospectively, and then patients were divided into the observation group 300 cases that received ESBD treatment and control group 265 cases that received EST treatment. Differences in intraoperative stress levels as well as postoperative inflammation, nutrition-related index and immune response levels were compared between two groups. Results: Intraoperative N, Cor, C-P and NK cell levels of observation group were lower than those of control group, and FT3 level was higher than that of control group; postoperative inflammation-related factors such as IL-6, CRP, PCT, CA19-9 and CEA levels were lower than those of control group, protein nutrition indexes such as TP, Alb, PA, TRF and RBP values were higher than those of control group, and immune indexes such as CD4+, CD4+/CD8+, IgA, IgM and IgG levels were higher than those of control group while CD8+ level was lower than that of control group. Conclusion: ESBD for the treatment of patients with common bile duct stones is better than EST treatment in reducing surgical stress, optimizing postoperative physical status and other aspects.

Situs inversus totalis (SIT) is a rare condition, in which there is transposition of the thoraco-abdominal organs. This situation leads to diagnostic and therapeutic difficulties in patients with acute surgical abdomen. The objective of this report is to present the case of a patient who presented with colonic pain in the epigastrium and left hypochondrium, in which the diagnosis of SIT, cholelithiasis and choledocholithiasis was reached after the respective imaging studies. Once the diagnosis was made, treatment was performed through retrograde endoscopic cholangiopancreatography (ERCP) and subsequent surgical exploration of bile ducts. Both procedures were failed due to technical difficulties generated by the patient's condition. In conclusion, in spite of the report of successful cases in the literature of ERCP and surgical treatment of the biliary tract in SIT, there may be situations that do not allow a successful approach, so meticulous surgical planning and the use of support methods are necessary In the management of these patients.

Advances in endoscopic retrograde cholangiopancreatography for the treatment of cholangiocarcinoma.

Science.gov (United States)

Uppal, Dushant S; Wang, Andrew Y

2015-06-25

Cholangiocarcinoma (CCA) is a malignancy of the bile ducts that carries high morbidity and mortality. Patients with CCA typically present with obstructive jaundice, and associated complications of CCA include cholangitis and biliary sepsis. Endoscopic retrograde cholangiopancreatography (ERCP) is a valuable treatment modality for patients with CCA, as it enables internal drainage of blocked bile ducts and hepatic segments by using plastic or metal stents. While there remains debate as to if bilateral (or multi-segmental) hepatic drainage is required and/or superior to unilateral drainage, the underlying tenant of draining any persistently opacified bile ducts is paramount to good ERCP practice and good clinical outcomes. Endoscopic therapy for malignant biliary strictures from CCA has advanced to include ablative therapies via ERCP-directed photodynamic therapy (PDT) or radiofrequency ablation (RFA). While ERCP techniques cannot cure CCA, advancements in the field of ERCP have enabled us to improve upon the quality of life of patients with inoperable and incurable disease. ERCP-directed PDT has been used in lieu of brachytherapy to provide neoadjuvant local tumor control in patients with CCA who are awaiting liver transplantation. Lastly, mounting evidence suggests that palliative ERCP-directed PDT, and probably ERCP-directed RFA as well, offer a survival advantage to patients with this difficult-to-treat malignancy.

Development and therapeutic application of internally emitting radiopharmaceuticals

This project is concerned with developing the potential of alpha-emitting radionuclides as agents for radiotherapy. Among the available α-emitters, astatine-211 appears most promising for testing the efficacy of α-emitters for therapeutic applications because: (1) it has some chemical similarities to iodine, an element that can readily be incorporated into numerous proteins and peptides; (2) it has a half life that is long enough to permit chemical manipulation yet short enough to minimize destruction of healthy cells; and (3) α-emission is associated with 100% of its decays. If appropriate biological carriers can be labeled with an alpha emitter such as 211 At, they could be of great utility in several areas of therapeutic medicine where elimination of specific cell populations is desired. While previous attempts to astatinate proteins using standard iodination techniques have been unsuccessful, effective labeling of proteins with astatine by first synthesizing an aryl astatide and then coupling this compound to the protein via an acylation has been achieved. Undergoing current investigation are several different aryl astatide-followed-by-acylation approaches including an astatinated Bolton-Hunter type reagent using concanavalin A (ConA) and melanocyte stimulating hormone (MSH) as model compounds

Choledocholithiasis is a real problem of major clinical importance. The incidence of cholelithiasis is 10-20%. We have examined 2907 patients treated with videolaparoscopic cholecystectomy (VLC) between January 2001 and September 2009. 214 cases (7.4%) were affected by choledocolithiasis; among these, 59 consecutive cases were treated by rendezvous, 151 cases by sequential treatment (ERCP-ES before VLC), 3 cases by extraction with Dormia's basket, and 1 case by ERCP-ES after VLC. The complications were one biliary fistula and three hemorrhages (one from the cystic artery, one from the hepatic area and one from trocar's site). The mean hospital stay was 1.38 +/- 0.83 days for the rendezvous group vs 4 53 +/- 0.74 days in the sequential treatment group (prendezvous procedure reduces hospital stay and has a greater compliance (only one treatment). We can use this option in the management of cases where preoperative ERCP-ES has failed.

The endoscopic ultrasound-guided rendezvous techniques (EUS-rendezvous) provide reliable biliary access after failed endoscopic retrograde cholangiopancreatography (ERCP) cannulation. We evaluated the clinical utility of an EUS-rendezvous technique using various approach routes. Patients undergoing EUS-rendezvous for biliary access after failed bile duct cannulation in ERCP were included. EUS-rendezvous was performed via three approach routes depending on the patient's condition: transgastric, transduodenal in a short endoscopic position, or transduodenal in a long endoscopic position. The main outcomes were the technical success rates. Secondary outcomes were procedure time and complications. Fourteen patients (median age, 77 years) underwent EUS-rendezvous for biliary access resulting from failed biliary cannulation. The reasons for biliary drainage were malignant biliary obstruction in five patients and choledocholithiasis in nine. Transgastric, transduodenal in a short position, and transduodenal in a long position EUS-rendezvous was performed in five, five, and four patients, respectively. Bile duct puncture occurred in the left intrahepatic duct in four patients, right hepatic duct in one, middle common bile duct in four, and lower common bile duct in five. The technical success rate was 100 %. In four patients, the approach route was modified from transduodenal in a short position to transduodenal in a long position or transgastric route. The median procedure time was 81 min. One case each of biliary peritonitis and pancreatitis occurred and were managed conservatively. EUS-rendezvous provided safe and reliable transpapillary bile duct access after failed ERCP cannulation. The selection of the appropriate approach routes, depending on patient condition, is critical.

We have evaluated the efficacy of ultrasonography (US) and computed tomography (CT) in comparison with endoscopic retrograde cholangiopancreatography (ERCP), percutaneous transhepatic cholangiography (PTC), and angiography (AG), and discussed a rational diagnostic approach for the evaluation of obstructive jaundice. The subjects were 70 patients with obstructive jaundice, finally confirmed by subsequent surgery or autopsy. In this study, US and CT achieved a diagnostic accuracy of 95% and 98%, respectively, in detection of the presence and level of an obstruction. Therefore, we consider that US is the best initial procedure for evaluation of obstructive jaundice; followed by CT only when the bilialy ducts should be poorly demonstrated by US because of body habitus or gaseous distension. US might be able to identify even the specific etiology of an obstructive lesion. In tumors of the bilialy tract and the pancreas including small and resectable ones, the diagnostic rate of US was high, 91% for bilialy tract tumor and 100% for pancreatic tumor, which was almost the same as that of ERCP, PTC or AG. This result suggests that US eliminates the need of invasive procedures in some cases before making decision of therapeutic approach, while CT was not so accurate diagnostic modality as US in small lesions. But in papillary tumors, small lesions of the distal common bile duct, and gallstone diseases, either ERCP or PTC yielding almost 100% diagnostic accuracy, is the most reliable procedure, while US or CT did not show a good diagnostic accuracy.

BACKGROUND: Complications in the biliary tract occur in 5%-30% after liver transplantation and the main part of the complications is successfully managed with endoscopic retrograde cholangiopancreaticography (ERCP). The incidence and risk factors for post-ERCP complications in liver transplantation...... patients are not well described. Our objective was to define the frequency of post-ERCP complications in liver transplantation patients at the Abdominal Center, Rigshospitalet, the only Liver Transplantation Center in Denmark. METHODS: Retrospective study of all ERCPs performed in liver transplantation...... and cholangitis occurred after two procedures, respectively. Multivariate analysis concerning overall complications identified biliary sphincterotomy (p = 0.006) and time since liver transplantation within 90 days postoperatively (p = 0.044) as risk factors for post-ERCP complications. Specifically concerning...

The following bibliographical research wanted to identify the main factors that influence adherence to treatment in chronic disease. The study focused on patients undergoing hemodialysis, as well as on the support nurses require for the promotion of health education among individuals with low treatment adherence. The identification of bibliographical sources was conducted at Health Virtual Library and Scientific Electronic Library Online (SciELO) data bases. Some printed magazines were also used. The results indicated nine factors influencing treatment adherence or non-adherence: team trust, support nets, educational level; accepting disease, treatment side effects, lack of access to medicines, long-term treatment, complex therapeutic approach, and lack of symptoms. It is advisable that nurses take into account these factors when dealing with chronic-disease patients that present low treatment adherence, getting family and multidisciplinary team support seeking treatment adherence.

Full Text Available Endoscopic retrograde cholangiopancreatography (ERCP is an important technique for the diagnosis and treatment of biliary and pancreatic diseases and post-ERCP pancreatitis (PEP is the most common complication of ERCP. Since the birth of ERCP, the prevention and treatment of PEP has become the focus of international research. In recent years, much progress has been made in the aspects of risk factors, pharmacological prevention, and prophylactic stent implantation in the pancreatic duct. Since these research findings are not consistent, further clinical studies are needed to demonstrate such findings.

We report on the successful treatment of small-cell prostate cancer in a patient undergoing haemodialysis. The therapeutic regimen included 300 mg/m(2) of carboplatin and 50 mg/m(2) of etoposide coupled with radical radiotherapy. Adjustments to the patient's haemodialysis prescription included the use of high flux, a larger dialyser surface area and an increased dialysis time. The parameters used aided tolerance to the drug, allowing the delivery of safe, effective treatment. At an interval of over 12 months post-treatment the patient shows no clinical evidence of recurrent disease. This case provides evidence to encourage the use of chemotherapy in otherwise potentially undertreated haemodialysed patients.

Therapeutic Mechanisms of Bile Acids and Nor-Ursodeoxycholic Acid in Non-Alcoholic Fatty Liver Disease.

2017-01-01

Non-alcoholic fatty liver disease is one of the most rapidly rising clinical problems in the 21st century. So far no effective drug treatment has been established to cure this disease. Bile acids (BAs) have a variety of signaling properties, which can be used therapeutically for modulating hepatic metabolism and inflammation. A side-chain shorted derivative of ursodeoxycholic acid (UDCA) is 24 nor-ursodeoxycholic acid (NorUDCA) and it represents a new class of drugs for treatment of liver diseases. NorUDCA has unique biochemical and therapeutic properties, since it is relatively resistant to conjugation with glycine or taurine compared to UDCA. NorUDCA undergoes cholehepatic shunting, resulting in ductular targeting, bicarbonate-rich hypercholeresis, and cholangiocyte protection. Furthermore, it showed anti-fibrotic, anti-inflammatory, and anti-lipotoxic properties in several animal models. As such, NorUDCA is a promising new approach in the treatment of cholestatic and metabolic liver diseases. This review is a summary of current BA-based therapeutic approaches in the treatment of the fatty liver disease. © 2017 S. Karger AG, Basel.

Inherited factor VII (FVII) deficiency is a rare coagulation disorder with variable haemorrhagic manifestations. In severely affected cases spontaneous haemarthroses leading to advanced arthropathy have been observed. Such cases may require surgery. Therapeutic options for bleeding prevention in FVII deficient patients undergoing surgery comprise various FVII preparations but the use of recombinant activated factor VII (rFVIIa) seems to be the treatment of choice. To present the outcome of orthopaedic surgery under haemostatic coverage of rFVIIa administered according to the locally established treatment regimen in five adult patients with FVII baseline plasma levels below 10 IU dL(-1). Two patients required total hip replacement (THR); three had various arthroscopic procedures. Recombinant activated factor VII was administered every 8 h on day of surgery (D0) followed by every 12-24 h for the subsequent 9-14 days, depending on the type of surgery. Factor VII plasma coagulation activity (FVII:C) was determined daily with no predefined therapeutic target levels. Doses of rFVIIa on D0 ranged from 18 to 37 μg kg(-1) b.w. and on the subsequent days--from 13 to 30 μg kg(-1) b.w. Total rFVIIa dose per procedure ranged from 16 to 37.5 mg, and the total number of doses per procedure was 16-31. None of our patients developed excessive bleeding including those in whom FVII:C trough levels returned nearly to the baseline level on the first post-op day. Preliminary results demonstrate that rFVIIa administered according to our treatment regimen is an effective and safe haemostatic agent for hypoproconvertinaemia patients undergoing orthopaedic surgery. © 2012 Blackwell Publishing Ltd.

In order to investigate the safety and efficacy of endoscopic retrograde cholangiopancreatograpy (ERCP) in liver cirrhosis patients with common bile duct stones, we retrospectively analyzed data of 46 common bile duct stones patients with liver cirrhosis who underwent ERCP between 2000 and 2008. There were 12 cases of Child-Pugh A, 26 cases of Child-Pugh B, and 8 cases of Child-Pugh C. 100 common bile duct stones patients without liver cirrhosis were randomly selected. All the patients were subjected to ERCP for biliary stones extraction. The rates of bile duct clearance and complications were compared between cirrhotic and non-cirrhotic patients. The success rate of selective biliary cannulation was 95.6% in liver cirrhotic patients versus 97% in non-cirrhotic patients (P>0.05). The bile duct clearance rate was 87% in cirrhotic patients versus 96% in non-cirrhotic patients, but the difference was not statistically significant. Two liver cirrhotic patients (4.35%, 2/46) who were scored Child-Pugh C had hematemesis and melena 24 h after ERCP. The hemorrhage rate after ERCP in non-cirrhotic patients was 3%. The hemorrhage rate associated with ERCP in Child-Pugh C patients was significantly higher (25%, 2/8) than that (3%, 3/100) in non-cirrhotic patients (Pbile duct stones. Hemorrhage risk in ERCP is higher in Child-Pugh C patients.

Environmental regulatory compliance plan, Deaf County site, Texas: Draft revision 1

The DOE is committed to conduct its operation in an environmentally safe and sound manner and comply with the letter and spirit of applicable environmental statues and regulations. These objectives are codified in DOE order N 5400.2, ''Environmental Policy Statement.'' This document, the Deaf Smith County site (Texas) Environmental Regulatory Compliance Plam (ERCP), is one means of implementing that policy. The ERCP describes the environmental regulatory requirements applicable to the Deaf Smith County site (Texas), and presented the framework within which the Salt Repository Project Office (SRPO) will comply with the requirements. The plan also discusses how DOE will address State and local environmental requirements. To achieve this purpose the ERCP will be developed in phases. This version of the ERCP is the first phase in the delopment of the ERCP. It represents the Salt Repository Project Office's understanding of environmental requirements for the site characterization phase of repository development. After consultation with the appropriate federal and state agencies and affected Indian tribes, the ERCP will be updated to reflect the results of consultation with these agencies and affected Indian tribes. 6 refs., 38 figs

Cholestasis caused by Fasciola gigantica.

Beştaş, Remzi; Yalçin, Kendal; Çiçek, Muttalip

2014-01-01

Fascioliasis is an infectious disease caused by the hepatic trematodes Fasciola hepatica and Fasciola gigantica. Here, we report the case of Fasciola gigantica presenting with biliary obstruction and abdominal pain that was diagnosed and treated by endoscopic retrograde cholangiography (ERCP). A 46-year-old woman presented with right upper quadrant abdominal pain and jaundice. Physical examination revealed icterus and hepatomegaly. Laboratory findings revealed an increase in liver transaminases and bilirubin. Abdominal ultrasonography showed extrahepatic and intrahepatic bile duct dilatation. The patient underwent ERCP. One live Fasciola gigantica was removed from the common bile duct by ERCP. In conclusion, fascioliasis should be considered in the differential diagnosis of obstructive jaundice, especially in endemic regions, and it should be kept in mind that ERCP plays an important role in the diagnosis and treatment of these patients. To our knowledge, this is the second case report of Fasciola gigantica treated by ERCP in Turkey.

The variety of rendezvous (RV) procedures has recently been extended by EUS- and PTCD-guided procedures as a complementary means to conventional ERCP. We have identified indication criteria and the potential of biliary PTCD-guided vs. EUS-guided RV. Consecutive patients with bile duct obstruction who underwent RV were included. In all, ERCP alone was unable to achieve treatment success. Indication, technical success, and outcome in PTCD- vs. EUS-guided RV were retrospectively compared to identify criteria that indicate preference of RV technique. Site of obstruction, clinical scenario (stenosis with abscess vs. no abscess) and reason for previous failure of ERC were evaluated. In 32 patients, three different indications for RV procedures were identified: First, a one-step access to assist in failed ERCP (type 1, intra-ductal RV); second, temporary drainage for prolonged treatment of complex biliary disease (type 2, intra-ductal RV), and drainage of cholangio-abscess with re-establishing bile outflow (type 3, intra-abscess RV). Indication of PTCD- vs. EUS-guided rendezvous was competitive in type 1, but exclusive in favor of PTCD in types 2 and 3. The site of biliary obstruction indicated the anatomic location of RV procedures. This classification may help to define inclusion criteria for prospective studies on biliary RV procedures. Choice of therapeutic strategy depends on the anatomic location of the biliary obstruction and the type of the biliary lesion. PTCD-guided RV might improve outcome in cholangio-abscess. © Georg Thieme Verlag KG Stuttgart · New York.

Bedside Endoscopic Retrograde Cholangiopancreatography Using Portable X-Ray in Acute Severe Cholangitis

2018-01-01

Full Text Available Patients with acute cholangitis require emergent biliary decompression. Those who are hemodynamically unstable on vasopressor support and mechanical ventilation are too critically ill to move outside of the intensive care unit. This prohibits performing Endoscopic Retrograde Cholangiopancreatography (ERCP in the endoscopy unit. Fluoroscopic guidance is required to confirm deep biliary cannulation during ERCP. There are a few reported cases of bedside ERCP using portable C-arm fluoroscopy unit or ultrasound guided cannulation. We present a unique case of life-saving emergent bedside ERCP in a severely ill patient with cholangitis and septic shock, using simple portable X-ray to confirm biliary cannulation.

Nanotechnological strategies for nerve growth factor delivery: Therapeutic implications in Alzheimer's disease.

Faustino, Célia; Rijo, Patrícia; Reis, Catarina Pinto

2017-06-01

Alzheimer's disease (AD) is a progressive neurodegenerative disorder associated with amyloid-β peptide misfolding and aggregation. Neurotrophic factors, such as nerve growth factor (NGF), can prevent neuronal damage and rescue the cholinergic neurons that undergo cell death in AD, reverse deposition of extracellular amyloid plaques and improve cognitive deficits. However, NGF administration is hampered by the poor pharmacokinetic profile of the therapeutic protein and its inability to cross the blood-brain barrier, which requires specialised drug delivery systems (DDS) for efficient NGF delivery to the brain. This review covers the main therapeutic approaches that have been developed for NGF delivery targeting the brain, from polymeric implants to gene and cell-based therapies, focusing on the role of nanoparticulate systems for the sustained release of NGF in the brain as a neuroprotective and disease-modifying approach toward AD. Lipid- and polymer-based delivery systems, magnetic nanoparticles and quantum dots are specifically addressed as promising nanotechnological strategies to overcome the current limitations of NGF-based therapies.

Demirjian, Aram N; Kent, Tara S; Callery, Mark P; Vollmer, Charles M

2010-01-01

Background Pancreatico-jejunostomy strictures (PJS) after pancreatiocoduodenectomy (PD) are poorly understood. Methods Patients treated for PJS were identified from all PDs (n =357) performed for all indications in our practice (2002 to 2009). Technical aspects of the original operation, as well as the presentation, management and outcomes of the resultant stricture were assessed. Results Seven patients developed a symptomatic PJS for an incidence of 2%. ‘Soft’ glands and small ducts (≤3 mm) were each present in 3/7 of the original anastomoses. Pancreatic fistula occurred in 6/7. The latency period to stricture presentation averaged 41 months. Diagnosis of PJS was confirmed by secretin magnetic resonance cholangio-pancreatography (MRCP). Therapeutic endoscopic retrograde cholangiopancreatography (ERCP) was attempted – each unsuccessfully – in four patients. All patients required operative correction of their PJS by takedown/revision of the original pancreatico-jejunal anastomoses (PJA) (n =4) ± a modified Puestow (n =2). One patient's PJS was completely inaccessible due to dense adhesions. Another patient's stricture recurred and was successfully revised with a stricturoplasty. At a mean follow-up of 25 months, all are alive, but only 4/7 are pain free. Conclusion A symptomatic PJS appears to be independent of original pathological, glandular or technical features but pancreatic fistulae may contribute. Secretin MRCP is diagnostically useful, whereas ERCP has been proven to be therapeutically ineffective. Durable resolution of symptoms after surgical revision is unpredictable. PMID:20815857

In most situations in veterinary medicine, glucocorticoids are the drugs of choice used, that is, to reduce the inflammatory response or limit an inappropriate immune response. Their use in long-term therapy may cause side effects that may weaken the patient. The aim of the study was to evaluate possible variations in the plasma potassium concentrations and their clinical relevance in dogs undergoing steroid therapy with methylprednisolone in anti-inflammatory doses. The study used a sample of 21 dogs (n = 21) presented for consultation, with a clinical condition requiring a corticosteroid therapeutic protocol with an anti-inflammatory dose of methylprednisolone. All the individuals were submitted to a corticosteroid therapeutic protocol administered orally during 18 days. During this period, 3 time points were considered: T0 (the day the prescription was first given), T1 (3 days later), and T2 (8 days later). Blood samples were collected from a peripheral vein to measure plasma potassium concentrations in T0, T1, and T2. Corticosteroid therapy on an outpatient basis statistically significantly decreased plasma potassium levels, especially between T1 and T2 (P = .03). The plasma potassium levels decreased in 12.5% of the males, compared with a decrease of 23.1% in the females. No statistically significant relationships were observe between the decreased plasma potassium levels and age, clinical condition, and patient׳s body weight. However, we found a statistically significant association between decreased plasma potassium levels and sex. The study results may justify the need for the systematic prescription of potassium supplements in patients undergoing steroid therapy, similar to what already occurs in human medicine.

Full Text Available Background: Carbon dioxide (CO 2 insufflation has been shown to be superior to air insufflation in colonoscopy, and double balloon enteroscopy. However, the value of CO 2 insufflation in endoscopic retrograde cholangiopancreatography (ERCP is not established. This study aims to assess the efficacy and safety of CO 2 insufflation during ERCP. Materials and Methods: Consecutive patients referred for ERCP at a single center were randomized to either air or CO 2 insufflation during ERCP. The primary objectives were a post-ERCP abdominal pain (measured by 10 cm visual analog scale [VAS] 30 and 90 min, and 3 h and 24 h after ERCP. Secondary objectives included end-tidal CO 2 (ETCO 2 values and procedural complications. Results: We randomized 298 patients; 149 into air group and 149 into CO 2 group. The VAS score for pain was higher in the air group compared to the CO 2 group at 30 min, with a median of 1 (interquartile range 1-0 versus median of 1 (interquartile range 1-0; P = 0.031 and 90 min after the procedure with a median of 0 (interquartile range 1-0 versus median of 0 (interquartile range 0-0; P = 0.006. There were no serious adverse events, and the ETCO 2 was within normal limits in both groups. Conclusions: CO 2 insufflation is superior to air insufflation during ERCP with regard to patient pain and discomfort and warrants wide adoption.

Premature coronary artery disease (PCAD) seems to increase, particularly in developing countries. Given the lack of such studies in the country, this study examines the prevalence, associated cardiovascular risk factors, and coronary angiographic profile of the disease in Iraq. Data was collected from a total of 445 adult patients undergoing coronary angiography at Duhok Heart Center, Kurdistan in a period between March and September 2014. Patients were divided into PCAD (male 70 % compared to lesser obstruction. Premature coronary artery disease is alarming  in the country. Cardiovascular risk factors are clustered among them. But the angiographic profile and therapeutic options of PCAD are close to those reported from previous studies.

Fluoroscopic procedures are an area of special concern in relation to radiation protection. The aim of this study was to describe the current level of patient radiation doses in endoscopic retrograde cholangiopancreatography (ERCP) collected from a single centre, as well as to establish and review local diagnostic reference levels (DRLs) in ERCP. A total of 100 patients' radiation doses in ERCP were recorded, and the third-quartile method was adopted to establish local DRLs for ERCP. The mean dose area product (DAP) was 2.05 Gy cm 2 , fluoroscopy time (FT) 1.7 min and the number of images was 3. The proposed local DRLs for ERCP were 3.00 Gy cm 2 and 3.0 min. Local DRLs were reviewed in a sample of 25 patients 5 y after they had been established. In reviewing data, the averages of DAP and FT were below the local DRLs. Local DRLs help in the optimisation process of fluoroscopic procedures and guides to a good clinical practice. (authors)

Laparoscopy has been used for the diagnosis and treatment for hemodynamically stable patients with penetrating abdominal trauma. This study evaluated whether diagnostic and therapeutic laparoscopy can be used as effectively in select patients with blunt abdominal trauma. All hemodynamically stable patients undergoing operations for blunt abdominal trauma over a 10-year period (2006-2015) at a tertiary medical center were included. Patients undergoing laparotomy were categorized as group A. Patients who underwent laparoscopy were categorized as group B. The clinical outcomes of the 2 groups were compared. There were 139 patients in group A and 126 patients in group B. Group A patients were more severely injured (mean injury severity score of 23.3 vs. 18.9, P .05). Laparoscopy is a feasible and safe tool for the diagnosis and treatment of hemodynamically stable patients with blunt abdominal trauma who require surgery.

Combined approach with therapeutic drug monitoring and pharmacogenomics in renal transplant recipients

Directory of Open Access Journals (Sweden)

S Manvizhi

2013-01-01

Full Text Available In patients undergoing renal transplantation, dose individualization for tacrolimus is routinely achieved with therapeutic drug monitoring (TDM. The patient started on 5.5 mg/day of tacrolimus had a significantly elevated tacrolimus trough concentration. The tacrolimus dose was regularly reduced following TDM at many time periods in the post transplant period but the tacrolimus concentration was consistently elevated. Genomic analysis done after four years revealed mutations in the genes encoding for CYP3A5 and MDR1 (2677G > T. Pharmacogenomics alongside TDM, will soon emerge as the backbone of dose individualization. But for genomics to be beneficial, it should be advocated in the pre-transplant or early post transplant period.

Current standard antithrombotic therapy after coronary stent implantation consists of lifelong aspirin and clopidogrel for a variable period depending in part on the stent type. Despite its well-established efficacy in reducing cardiac-related death, myocardial infarction, and stroke, dual antiplatelet therapy with aspirin and clopidogrel is not without shortcomings. While clopidogrel may be of little beneficial effect if administered immediately prior to PCI and may even increase major bleeding risk if coronary artery bypass grafting is anticipated, early discontinuation of the drug may result in insufficient antiplatelet coverage with thrombotic complications. Optimal and rapid inhibition of platelet activity to suppress ischemic and thrombotic events while minimizing bleeding complications is an important therapeutic goal in the management of patients undergoing percutaneous coronary intervention. In this article we present an overview of the literature on clinical trials evaluating the different aspects of antithrombotic therapy in patients

2018-01-01

Full Text Available Purpose: Functional characteristics and durability of the artificial urinary sphincter (AUS among patients who develop bladder cancer has been poorly characterized. We sought to evaluate AUS outcomes among patients subsequently diagnosed with bladder cancer, in order to describe device survivability when subject to diagnostic and therapeutic procedures such as cystoscopy, transurethral resection, and cystectomy. Materials and Methods: We retrospectively reviewed 1,803 male patients treated with AUS surgery at a single institution between 1983–2014. We describe AUS device outcomes among patients undergoing surveillance and treatment for bladder cancer. Results: Following AUS placement, 14 (0.8% patients were subsequently diagnosed with and treated for bladder cancer and 4 patients with bladder cancer undergoing treatment and screening, subsequently received AUS placement. The median follow-up from device placement was 7.2 years (interquartile range [IQR], 2.8–11.5, and the median time from AUS placement to bladder cancer diagnosis was 6 (IQR, 0–9. There were a total of 8 primary and 1 secondary devices failures. Despite a median of 2 diagnostic cystoscopies (IQR, 1–6 and 0 bladder tumor resections (IQR, 0–0 per patient following device implantation, only 1 (5.6% patient experienced an iatrogenic erosion related to urethral manipulation. Among those undergoing cystectomy (n=4, 1 device was left in situ without complication. Conclusions: Bladder cancer surveillance and treatment with an AUS device in place appears to confer minimal additional risk to AUS survival. Careful attention should be given to device deactivation and use of the smallest caliber instruments available to minimize the risk of iatrogenic urethral erosion.

The therapeutic implications of plasticity of the cancer stem cell phenotype.

Directory of Open Access Journals (Sweden)

Kevin Leder

2010-12-01

Full Text Available The cancer stem cell hypothesis suggests that tumors contain a small population of cancer cells that have the ability to undergo symmetric self-renewing cell division. In tumors that follow this model, cancer stem cells produce various kinds of specified precursors that divide a limited number of times before terminally differentiating or undergoing apoptosis. As cells within the tumor mature, they become progressively more restricted in the cell types to which they can give rise. However, in some tumor types, the presence of certain extra- or intracellular signals can induce committed cancer progenitors to revert to a multipotential cancer stem cell state. In this paper, we design a novel mathematical model to investigate the dynamics of tumor progression in such situations, and study the implications of a reversible cancer stem cell phenotype for therapeutic interventions. We find that higher levels of dedifferentiation substantially reduce the effectiveness of therapy directed at cancer stem cells by leading to higher rates of resistance. We conclude that plasticity of the cancer stem cell phenotype is an important determinant of the prognosis of tumors. This model represents the first mathematical investigation of this tumor trait and contributes to a quantitative understanding of cancer.

Active videogames (AVGs) may be useful for promoting physical activity for therapeutic uses, including for balance, rehabilitation, and management of illness or disease. The literature from 64 peer-reviewed publications that assessed health outcomes of AVGs for therapeutic purposes was synthesized. PubMed, Medline, and PyschInfo were queried for original studies related to the use of AVGs to improve physical outcomes in patients who were ill or undergoing rehabilitation related to balance, burn treatment, cancer, cerebral palsy, Down's syndrome, extremity dysfunction or amputation, hospitalization, lupus, Parkinson's disease, spinal injury, or stroke. The following inclusion criteria were used: (1) human subjects; (2) English language; (3) not duplicates; (4) new empirical data; and (5) tests an AVG, including commercially available or custom-designed. Studies were included regardless of participants' age or the study design. Overall, the vast majority of studies demonstrated promising results for improved health outcomes related to therapy, including significantly greater or comparable effects of AVG play versus usual care. However, many studies were pilot trials with small, homogeneous samples, and many studies lacked a control or comparison group. Some trials tested multiweek or multimonth interventions, although many used a single bout of gameplay, and few included follow-up assessments to test sustainability of improved health. AVGs were acceptable and enjoyable to the populations examined and appear as a promising tool for balance, rehabilitation, and illness management. Future research directions and implications for clinicians are discussed.

To better define the prevalence and location of full-thickness articular cartilage lesions in elite football players undergoing knee magnetic resonance imaging (MRI) at the National Football League (NFL) Invitational Combine and assess the association of these lesions with previous knee surgery. We performed a retrospective review of all participants in the NFL Combine undergoing a knee MRI scan from 2005 to 2009. Each MRI scan was reviewed for evidence of articular cartilage disease. History of previous knee surgery including anterior cruciate ligament reconstruction, meniscal procedures, and articular cartilage surgery was recorded for each athlete. Knees with a history of previous articular cartilage restoration surgery were excluded from the analysis. A total of 704 knee MRI scans were included in the analysis. Full-thickness articular cartilage lesions were associated with a history of any previous knee surgery (P football players at the NFL Combine undergoing MRI. The lateral compartment appears to be at greater risk for full-thickness cartilage loss. Previous knee surgery, particularly meniscectomy, is associated with these lesions.

Background Early prognosis in comatose survivors after cardiac arrest due to ventricular fibrillation (VF) is unreliable, especially in patients undergoing mild hypothermia. We aimed at developing a reliable risk-score to enable early prediction of cerebral performance and survival. Methods Sixty-one out of 239 consecutive patients undergoing mild hypothermia after cardiac arrest, with eventual return of spontaneous circulation (ROSC), and comatose status on admission fulfilled the inclusion criteria. Background clinical variables, VF time and frequency domain fundamental variables were considered. The primary and secondary outcomes were a favorable neurological performance (FNP) during hospitalization and survival to hospital discharge, respectively. The predictive model was developed in a retrospective cohort (n=32; September 2006–September 2011, 48.5 ± 10.5 months of follow-up) and further validated in a prospective cohort (n = 29; October 2011–July 2013, 5 ± 1.8 months of follow-up). Results FNP was present in 16 (50.0%) and 21 patients (72.4%) in the retrospective and prospective cohorts, respectively. Seventeen (53.1%) and 21 patients (72.4%), respectively, survived to hospital discharge. Both outcomes were significantly associated (p < 0.001). Retrospective multivariate analysis provided a prediction model (sensitivity= 0.94, specificity = 1) that included spectral dominant frequency, derived power density and peak ratios between high and low frequency bands, and the number of shocks delivered before ROSC. Validation on the prospective cohort showed sensitivity = 0.88 and specificity = 0.91. A model-derived risk-score properly predicted 93% of FNP. Testing the model on follow-up showed a c-statistic ≥ 0.89. Conclusions A spectral analysis-based model reliably correlates time-dependent VF spectral changes with acute cerebral injury in comatose survivors undergoing mild hypothermia after cardiac arrest.

Endoscopic retrograde cholangiopancreatography (ERCP) procedure is an invasive technique that requires fluoroscopic and radiographic exposure. The purpose of this study was to determine the occupational dose of ionising radiation at three gastroenterology departments (Fedial, Soba and Ibn seena hospitals) in Khartoum (Sudan). The radiation dose was measured during 55 therapeutic ERCP procedures. Thermoluminescence dosemeters were used. The mean radiation dose for the first operator was 0.27 mGy for the eye lens, 0.21 for the thyroid, 0.32 for the chest, 0.17 for the hand and 0.22 for the leg. The mean radiation dose for the second operator was 0.21 mGy for the hand and 0.20 mGy for the chest, while the mean radiation dose for the nurse was 0.44 mGy for the hand and 0.19 for the chest. The radiation dose received by the staff in these hospitals was found to be higher than most of the values in the literature. The radiation absorbed dose received by the different organs is relatively low. Additional studies need to be conducted for radiation dose optimisation. (authors)

To evaluate the influence of preoperative low-level laser therapy (LLLT) on therapeutic outcomes of dogs undergoing tibial plateau levelling osteotomy (TPLO). Healthy dogs undergoing TPLO were randomly assigned to receive either a single preoperative LLLT treatment (800-900 nm dual wavelength, 6 W, 3.5 J/cm 2 , 100 cm 2 area) or a sham treatment. Lameness assessment and response to manipulation, as well as force plate analysis, were performed preoperatively, then again at 24 hours, two weeks, and eight weeks postoperatively. Radiographic signs of healing of the osteo-tomy were assessed at eight weeks postoperatively. Twenty-seven dogs (27 stifles) were included and no major complications occurred. At eight weeks postoperatively, a significant difference in peak vertical force analysis was noted between the LLLT (39.6% ± 4.7%) and sham groups (28.9% ± 2.6%), (p dogs in the LLLT group (6.6 ± 1.6 years) was greater than that for the sham group (4.5 ± 2.0, p dogs (5/8) had healed at the eight-week time point than in the sham group (3/12) despite the age difference (p = 0.11) Clinical significance: The results of this study demonstrate that improved peak vertical force could be related to the preoperative use of LLLT for dogs undergoing TPLO at eight weeks postoperatively. The use of LLLT may improve postoperative return to function following canine osteotomies and its use is recommended.

We report a case of absolute vitamin K deficiency (VKD) diagnosed by measuring serum VK levels in an elderly woman undergoing warfarin therapy. A 78-year-old woman was admitted to our hospital because of dyspnea and sore throat diagnosed as pharyngitis 1 week before admission. On admission, the sore throat had exacerbated and dyspnea developed. She had history of atrial fibrillation, for which warfarin 1.5 mg/d was started approximately 10 years prior and her international normalized ratio (INR) had been maintained at an acceptable therapeutic level. Blood results revealed unmeasurable INR and abnormally prolonged activated partial thromboplastin time (APTT). She was diagnosed with adenoiditis and warfarin-related coagulopathy and administered intravenous VK (20 mg) and fresh frozen plasma (FFP; 4 U), which improved INR and APTT. Since the coagulopathy responded to intravenous VK administration, the patient was clinically diagnosed with warfarin-related relative VKD. Approximately 1 month later, she returned with complaints of sore throat. Blood results indicated abnormal INR (7.22) and APTT (N80.0 s). She was diagnosed with recurrent adenoiditis and VK deficient coagulopathy. The patient’s serum VK levels were low (VK1 level, 0.13 ng/mL; VK2 levels, 0.85 ng/mL). Initial treatment of VK (20 mg) and FFP followed by intravenous VK (20 mg/d) for 6 days, her symptoms dissipated. Warfarin was suspected to have caused absolute VKD. Severe coagulopathy in patients undergoing warfarin therapy is primarily caused by, relative VKD. However, the possibility of warfarin-related absolute VKD should be suspected when INRis not sufficiently improved by intravenous VK administration.

Aim: To evaluate MR cholangio-pancreatography (MRCP) using an open low magnetic field apparatus in normals and in patients with mechanical cholestasis. Methods: MRCP was performed on five normals and on 30 patients, using both an 0.2 Tesla and 1.5 Tesla apparatus. With the low field system, rapid acquisition by relaxation enhancement was used, for the high field system, half Fourier acquisition single shot turbo spin-echo sequences were used. In all patients, sonography and ERCP of PTC was performed; 23 underwent surgery. Results: In all normals it was possible to show the bile duct, hepatic duct, gall bladder and intrahepatic ducts of the first order. Using the high field system, second order ducts could be shown and sometimes third order ducts. In the patients, MRCP, using either system, demonstrated all 21 obstructive sites due to tumours or stenoses. Stones were shown in 69% by the low field system and in 88% by the high field system. Conclusion: MRCP can be successfully carried out using the low field system. In the presence of mechanical cholestasis, image quality is adequate for the localisation of stenoses and occlusions, and using an open magnet, is suitable for planning further intervention. (orig.)

To address endoscopic outcomes of post-Orthotopic liver transplantation (OLT) patients diagnosed with a "redundant bile duct" (RBD). Medical records of patients who underwent OLT at the Liver Transplant Center, University Texas Health Science Center at San Antonio Texas were retrospectively analyzed. Patients with suspected biliary tract complications (BTC) underwent endoscopic retrograde cholangiopancreatography (ERCP). All ERCP were performed by experienced biliary endoscopist. RBD was defined as a looped, sigmoid-shaped bile duct on cholangiogram with associated cholestatic liver biomarkers. Patients with biliary T-tube placement, biliary anastomotic strictures, bile leaks, bile-duct stones-sludge and suspected sphincter of oddi dysfunction were excluded. Therapy included single or multiple biliary stents with or without sphincterotomy. The incidence of RBD, the number of ERCP corrective sessions, and the type of endoscopic interventions were recorded. Successful response to endoscopic therapy was defined as resolution of RBD with normalization of associated cholestasis. Laboratory data and pertinent radiographic imaging noted included the pre-ERCP period and a follow up period of 6-12 mo after the last ERCP intervention. One thousand two hundred and eighty-two patient records who received OLT from 1992 through 2011 were reviewed. Two hundred and twenty-four patients underwent ERCP for suspected BTC. RBD was reported in each of the initial cholangiograms. Twenty-one out of 1282 (1.6%) were identified as having RBD. There were 12 men and 9 women, average age of 59.6 years. Primary indication for ERCP was cholestatic pattern of liver associated biomarkers. Nineteen out of 21 patients underwent endoscopic therapy and 2/21 required immediate surgical intervention. In the endoscopically managed group: 65 ERCP procedures were performed with an average of 3.4 per patient and 1.1 stent per session. Fifteen out of 19 (78.9%) patients were successfully managed with

Recruiting Terminally Ill Patients into Non-Therapeutic Oncology Studies: views of Health Professionals

Full Text Available Abstract Background Non-therapeutic trials in which terminally ill cancer patients are asked to undergo procedures such as biopsies or venipunctures for research purposes, have become increasingly important to learn more about how cancer cells work and to realize the full potential of clinical research. Considering that implementing non-therapeutic studies is not likely to result in direct benefits for the patient, some authors are concerned that involving patients in such research may be exploitive of vulnerable patients and should not occur at all, or should be greatly restricted, while some proponents doubt whether such restrictions are appropriate. Our objective was to explore clinician-researcher attitudes and concerns when recruiting patients who are in advanced stages of cancer into non-therapeutic research. Methods We conducted a qualitative exploratory study by carrying out open-ended interviews with health professionals, including physicians, research nurses, and study coordinators. Interviews were audio-recorded and transcribed. Analysis was carried out using grounded theory. Results The analysis of the interviews unveiled three prominent themes: 1 ethical considerations; 2 patient-centered issues; 3 health professional issues. Respondents identified ethical issues surrounding autonomy, respect for persons, beneficence, non-maleficence, discrimination, and confidentiality; bringing to light that patients contribute to science because of a sense of altruism and that they want reassurance before consenting. Several patient-centered and health professional issues are having an impact on the recruitment of patients for non-therapeutic research. Facilitators were most commonly associated with patient-centered issues enhancing communication, whereas barriers in non-therapeutic research were most often professionally based, including the doctor-patient relationship, time constraints, and a lack of education and training in research

Periprocedural myocardial injury (PMI) following percutaneous coronary intervention (PCI) has received great attention due to its significant association with mortality and morbidity. Accordingly, cardioprotection during PCI is one of the important therapeutic concerns. Regarding the potential cardiovascular benefits of pentoxifylline this study was performed to evaluate whether the pretreatment pentoxifylline could reduce PMI in patients who are undergoing elective PCI. A randomized clinical trial on 85 patients undergoing elective PCI was performed. The intervention group (n = 41) received 1200 mg pentoxifylline in divided doses plus the standard treatment before PCI, while the control group (n = 44) received the standard treatment. For assessing myocardial damage during PCI, the levels of CK-MB and troponin-I were measured at baseline, 8, and 24 h after the procedure. Then, patients were followed up for a 1-month period regarding the major adverse cardiac effect. Comparing with the control group, no significant change of CK-MB at 8 (p = 0.315) and 24 h (p = 0.896) after PCI was documented in pentoxifylline group. Similarly, no significant change was found in troponin-I at 8 (p = 0.141) and 24 h (p = 0.256) after PCI. This study could not support the pretreatment with pentoxifylline in the prevention of PMI in patients undergoing elective PCI. However, the trend was toward the potential benefit of pentoxifylline.

Laparoscopy is increasingly utilised as a diagnostic tool in management of abdominal trauma; however its role in therapeutic intervention remains unexplored. The aim of this study is to compare laparoscopy with laparotomy in the treatment of abdominal trauma in haemodynamically stable patients. A review of patients undergoing surgery for abdominal trauma between January 2004-2014 identified 25 patients who underwent laparoscopy for therapeutic intervention (TL). This group was matched with 25 similar patients undergoing laparotomy (LT). Matching of the two cohorts was based on patient characteristics, severity of injuries, haemodynamic compromise and radiological findings. Peri-operative outcomes were compared. Patient characteristics were similar in TL and LT patients for age (median 33 vs. 26 years), gender distribution and clinical presentation. Injury severity score was also similar with a median of 16 in both groups (major trauma = ISS>15, normal range 0-75). Types of injuries included; hollow viscus [bowel repair = 10 (TL) vs. 16 (LT)] and solid organs [5(TL) vs. 2 (LT)]. Median operating time was similar in both groups; 105(TL) compared to 98 (LT) minutes. Post-operative complications (1 vs. 10, p = 0.02), analgesia requirements, specifically opiate use (34 vs. 136 morphine equivalents, p = 0.002) and hospital stay (4 vs. 9 days, p = 0.03) were significantly lower in the laparoscopy group. Abdominal trauma in haemodynamically stable patients can be managed effectively and safely with laparoscopy by experienced surgeons. Major benefits may include lower morbidity, reduced pain, and shorter length of hospital stay. Crown Copyright © 2017. Published by Elsevier Ltd. All rights reserved.

The optimal timing and best method for removal of common bile duct stones (CBDS) associated with gallbladder stones (GBS) is still controversial. The aim of this study is to investigate the outcomes of a single-step procedure combining laparoscopic cholecystectomy (LC), intraoperative cholangiography (IOC), and endoscopic retrograde cholangiopancreatography (ERCP). Between January 2003 and January 2012, 1972 patients underwent cholecystectomy at our hospital. Of those, 162 patients (8.2%; male/female 72/90) presented with GBS and suspected CBDS. We treated 54 cases (Group 1) with ERCP and LC within 48 to 72 hours. In 108 patients (Group 2) we performed LC with IOC and, if positive, was associated with IO-ERCP and sphincterotomy. In Group 1, a preoperative ERCP and LC were completed in 50 patients (30%). In four cases (2%), an ERCP and endobiliary stents were performed without cholecystectomy and then patients were discharged because of the severity of clinical conditions and advanced American Society of Anesthesiologists score (III to IV). Two months later a preoperative ERCP and removal of biliary stents were performed followed by LC 48 to 72 hours later. In Group 2, the IOC was performed in all cases and CBDS were extracted in 94 patients (87%). In two cases, the laparoscopic choledochotomy was necessary to remove large stones. In another two cases, an open choledochotomy was performed to remove safely the stones with T-tube drainage. In three cases, conversion was necessary to safely complete the procedure. The mean operative time was 95 minutes (range, 45 to 150 minutes) in Group 1 and 130 minutes (range, 50 to 300 minutes) in Group 2. The mean hospital stay was 6.5 days (range, 4 to 21 days) in Group 1 and 4.7 days (range, 3 to 14 days) in Group 2. Five cases (two in Group 2 and three in Group 1) presented with CBDS at 12 to 18 months after surgery. They were treated successfully with a second ERCP. There was no perioperative mortality.

Contrast-Induced Nephropathy in Patients Undergoing Percutaneous Coronary Intervention

Sana Shoukat

2010-01-01

Full Text Available Contrast Induced Nephropathy (CIN is a feared complication of numerous radiological procedures that expose patients to contrast media. The most notorious of these procedures is percutaneous coronary intervention (PCI. Not only is this a leading cause of morbidity and mortality, but it also adds to increased costs in high risk patients undergoing PCI. It is thought to result from direct cytotoxicity and hemodynamic challenge to renal tissue. CIN is defined as an increase in serum creatinine by either ≥0.5 mg/dL or by ≥25% from baseline within the first 2-3 days after contrast administration, after other causes of renal impairment have been excluded. The incidence is considerably higher in diabetics, elderly and patients with pre-existing renal disease when compared to the general population. The nephrotoxic potential of various contrast agents must be evaluated completely, with prevention as the mainstay of focus as no effective treatment exists. The purpose of this article is to examine the pathophysiology, risk factors, and clinical course of CIN, as well as the most recent studies dealing with its prevention and potential therapeutic interventions, especially during PCI. The role of gadolinium as an alternative to iodinated contrast is also discussed.

A high level of preoperative anxiety is common among patients undergoing medical and surgical procedures. Anxiety impacts of gastroenterological procedures on psychological and physiological responses are worth consideration. To analyze the effect of listening to Vedic chants and Indian classical instrumental music on anxiety levels and on blood pressure (BP), heart rate (HR), and oxygen saturation in patients undergoing upper gastrointestinal (GI) endoscopy. A prospective, randomized controlled trial was done on 199 patients undergoing upper GI endoscopy. On arrival, their anxiety levels were assessed using state and trait scores and various physiological parameters such as HR, BP, and SpO 2 . Patients were randomly divided into three groups: Group I of 67 patients who were made to listen prerecorded Vedic chants for 10 min, Group II consisting of 66 patients who listened to Indian classical instrumental music for 10 min, and Group III of 66 controls who remained seated for same period in the same environment. Thereafter, their anxiety state scores and physiological parameters were reassessed. A significant reduction in anxiety state scores was observed in the patients in Group I (from 40.4 ± 8.9 to 38.5 ± 10.7; P classical instrumental music has beneficial effects on alleviating anxiety levels induced by apprehension of invasive procedures and can be of therapeutic use.

To evaluate the safety and efficacy of limited endoscopic sphincterotomy (ES) before placement of self-expandable metal stent (SEMS). This was a retrospective analysis of 244 consecutive patients with unresectable malignant biliary obstruction, who underwent placement of SEMSs following limited ES from December 2008 to February 2015. The diagnosis of malignant biliary obstruction and assessment of patient eligibility for the study was established by a combination of clinical findings, laboratory investigations, imaging and pathological results. All patients were monitored in the hospital for at least 24 h following endoscopic retrograde cholangio pancreatography (ERCP). The incidence of immediate or early post-ERCP complications such as post-ERCP pancreatitis (PEP) and bleeding related to limited ES were considered as primary outcomes. Also, characteristics and complications according to the cancer type were classified. Among the 244 patients included, the underlying diagnosis was cholangiocarcinoma in 118 patients, pancreatic cancer in 79, and non-pancreatic or non-biliary malignancies in the remaining 47 patients. Early post-ERCP complications occurred in 9 patients (3.7%), with PEP in 7 patients (2.9%; mild, 6; moderate, 1) and mild bleeding in 2 patients (0.8%). There was no significant association between the incidence of post-ERCP complications and the type of malignancy (cholangiocarcinoma vs pancreatic cancer vs others, P = 0.696) or the type of SEMS used (uncovered vs covered, P = 1.000). Patients who had more than one SEMS placed at the first instance were at a significantly higher risk of post-ERCP complications (one SEMS vs two SEMS, P = 0.031). No other factors were predictive of post-ERCP complications. Limited ES is feasible and safe, and effectively facilitates the placement of SEMS, without any significant risk of PEP or severe bleeding.

ERCP combines endoscopic and radiologic techniques in order to obtain high quality opacification of pancreatic and biliary ducts. The rate of success for cannulation was 90%; desired duct opacification was possible in 89%. The most frequent indication for ERCP was to establish the differential diagnosis for jaundice; biliary stones in the common bile duct was the most frequent diagnosis, followed by normal biliary ducts. Pancreatography was normal in 74% of patients. ERCP complications were detected in 5.6%; fever and transient pain was the most common complaint in 1.6%. Mortality attributable to the procedure was 0.8%. From histological corroboration of cases by surgery or postmortem studies, diagnostic sensitivity was 92%, specificity 76%, positive predictive value 96% and a prevalence of 89%. We conclude that ERCP is highly sensitive and specific in diagnosing bilio-pancreatic-duodenal disease. Our results are comparable to other's experiences published throughout the world.

To compare digital tomosynthesis with endoscopic retrograde cholangiopancreatography (ERCP) for the evaluation of common bile duct (CBD) stones as a complementary diagnostic tool. Ninety six consecutive patients clinically suspected of having CBD stones underwent ERCP and digital tomosynthesis over 22 months, from December, 2008 to May, 2010. Fourteen patients were excluded. Therefore 82 patients were included in this study. The images were retrospectively reviewed to compare the results with the final analysis based on the consensus of two abdominal radiologists. An evaluation of the presence of CBD stones was followed by a determination of the margins for the stones, scored with a five-point conspicuity scale. Among the 82 patients, 54 collectively had 89 CBD stones and 28 had no stones. The sensitivity and specificity for the detection of CBD stones were 91.0% and 80.6% for ERCP, 92.1% and 93.5% for digital tomosynthesis, respectively. The average score was 3.29 for ERCP and 3.89 for digital tomosynthesis in 77 similar detected stones. Digital tomosynthesis demonstrated significantly better conspicuity than ERCP (p = 0.001). Digital tomosynthesis is an effective and complementary diagnostic method for the evaluation of CBD stones.

The intraoperative use of endoscopic retrograde cholangiopancreatography (ERCP) during laparoscopic cholecystectomy (LC) is a safe, single-stage option for the management of concomitant gallstones (GS) and common bile duct stones (CBDS). This study aims to compare between 2 techniques of combined laparoendoscopic management, which are laparoendoscopic Rendez-vous (LC/LERV) technique and standard ERCP after the completion of LC intraoperative endoscopic sphincterotomy (IOES). Patients with GS and suspected CBDS were included. They were divided into 2 groups; LC/LERV and LC/IOES. Both groups were compared for failure of endoscopic sphincterotomy/stone extraction, operative time, conversion rate, mortality/morbidity, and length of hospital stay. Between October 2007 and February 2010, 98 patients with GS and CBDS were eligible for inclusion in the study. They were prospectively randomized into 2 groups; LC/LERV (N=45) and LC/IOES (N=53). There were no differences in preoperative parameters between both groups. There was a significant difference in operative time (shorter for LC/IOES). No difference was noted in success/failure rate, post-ERCP pancreatitis. Both Standard ERCP after the completion of LC and LC/LERV are valid single-session management for CBD stones, but LC-ERCP may be preferred.

We have reviewed the endoscopic retrograde cholangiopancreatography (ERCP) images of patients with autoimmune pancreatitis (AIP) and pancreatic carcinoma (Pca) in an attempt to identify findings that would facilitate making a differential diagnosis between AIP and Pca. The study cohort consisted of 39 patients diagnosed with AIP and 62 patients diagnosed with Pca. The ERCP findings in the pancreatic duct and biliary tract were compared between the two groups. The ERCP images revealed that AIP patients had a higher prevalence of narrowing of the main pancreatic duct (MPD) for ≥3 cm of its length and a higher prevalence for the presence of side branches in the narrowed portion of the MPD than Pca patients (p 5 cm of its length and the presence of side branches. Among our patient cohort, the ERCP findings in terms of the length of the narrowed portion of the MPD, the presence of side branches, and maximal diameter of the upstream MPD enabled differential diagnosis between AIP and Pca in most of the cases. However, it must be borne in mind that some Pca patients have ERCP findings similar to those of AIP patients. (author)

We aimed to evaluate the efficiency and safety of one-step procedure combined endoscopic retrograde cholangiopancreatography (ERCP) and laparoscopic cholecystectomy (LC) for treatment of patients with cholecysto-choledocholithiasis. A prospective randomized study was performed on 63 consecutive cholecysto-choledocholithiasis patients during 2008 and 2011. The efficiency and safety of one-step procedure was assessed by comparing the two-step LC with ERCP + endoscopic sphincterotomy (EST). Outcomes including intraoperative features, postoperative features (length of stay and postoperative complications) were evaluated. One- or two-step procedure of LC with ERCP + EST was successfully performed in all patients, and common bile duct stones were completely removed. Statistical analyses showed that length of stay and pulmonary infection rate were significantly lower in the test group compared with that in the control group (P 0.05). The one-step procedure of LC with ERCP + EST is superior to the two-step procedure for treatment of patients with cholecysto-choledocholithiasis regarding to the reduced hospital stay and inhibited occurrence of pulmonary infections. Compared with two-step procedure, one-step procedure of LC with ERCP + EST may be a superior option for cholecysto-choledocholithiasis patients treatment regarding to hospital stay and pulmonary infections.

Recent studies show that proinflammatory cytokines might be related to the development of opioid dependence (physiological, psychological, or both). In a double-blind, randomly stratified clinical trial investigating whether add-on dextromethorphan (60-120 mg/day) attenuated inflammation and the combined use of opioids in heroin-dependent patients undergoing methadone maintenance treatment, we evaluated whether inflammation is related to the progression of opioid dependence. All participants (107 heroin-dependent patients and 84 nondependent healthy controls) were recruited from National Cheng Kung University Hospital. Their plasma cytokine levels were measured to evaluate the effect of add-on dextromethorphan. Plasma TNF-α and IL-8 levels were significantly higher in long-term heroin-dependent patients than in healthy controls (p dextromethorphan. Moreover, both tolerance to methadone and the combined use of opioids were significantly (p dextromethorphan. We conclude that dextromethorphan might be a feasible adjuvant therapeutic for attenuating inflammation and inhibiting methadone tolerance and combined opioid use in heroin-dependent patients.

2014-01-21

Monoclonal antibodies (mAbs) are powerful therapeutics, and their characterization has drawn considerable attention and urgency. Unlike small-molecule drugs (150-600 Da) that have rigid structures, mAbs (∼150 kDa) are engineered proteins that undergo complicated folding and can exist in a number of low-energy structures, posing a challenge for traditional methods in structural biology. Mass spectrometry (MS)-based biophysical characterization approaches can provide structural information, bringing high sensitivity, fast turnaround, and small sample consumption. This review outlines various MS-based strategies for protein biophysical characterization and then reviews how these strategies provide structural information of mAbs at the protein level (intact or top-down approaches), peptide, and residue level (bottom-up approaches), affording information on higher order structure, aggregation, and the nature of antibody complexes.

The anesthetic management of adolescents undergoing bariatric surgery presents a number of challenges, including increased risk of postoperative opioid-related respiratory depression. These patients could benefit from adjunctive analgesics with opioid-sparring effects to optimize perioperative pain control. Dexmedetomidine, a selective α2-adrenoreceptor agonist, has sedative and analgesic properties with no respiratory depressant effects. To determine the effect of intraoperative dexmedetomidine on opioid requirement and perioperative pain management in obese adolescents undergoing bariatric surgery. An observational study of 26 consecutive patients treated with and without dexmedetomidine during the intraoperative period was conducted. The dexmedetomidine treated patients received a loading dose over 30min and a continuous infusion thereafter. The standard group represented patients who received an institutional standard anesthetic without dexmedetomidine. The primary outcome was total perioperative intravenous morphine equivalent (MEq). We also examined reported pain scores during the perioperative period. While there were no significant differences in age, height and weight category, there were imbalances on race distribution between the two groups. Both groups received similar doses of ketorolac and acetaminophen perioperatively. Overall, during 48h postoperatively, the dexmedetomidine group received significantly less total MEq administration compared with the standard group. Three patients in the dexmedetomidine group required ephedrine to treat an episode of hypotension. These results suggest that the use of dexmedetomidine during bariatric surgery in the morbidly obese adolescent population is associated with decreased opioid utilization during the perioperative period. Future randomized studies will determine the role of dexmedetomidine in the pain management of obese adolescents undergoing bariatric surgery. Therapeutic, Level III. Copyright © 2017

Bellissimo, Francesco; Pinzone, Marilia Rita; Cacopardo, Bruno; Nunnari, Giuseppe

2015-01-01

Hepatocellular carcinoma (HCC) is an increasing health problem, representing the second cause of cancer-related mortality worldwide. The major risk factor for HCC is cirrhosis. In developing countries, viral hepatitis represent the major risk factor, whereas in developed countries, the epidemic of obesity, diabetes and nonalcoholic steatohepatitis contribute to the observed increase in HCC incidence. Cirrhotic patients are recommended to undergo HCC surveillance by abdominal ultrasounds at 6-mo intervals. The current diagnostic algorithms for HCC rely on typical radiological hallmarks in dynamic contrast-enhanced imaging, while the use of α-fetoprotein as an independent tool for HCC surveillance is not recommended by current guidelines due to its low sensitivity and specificity. Early diagnosis is crucial for curative treatments. Surgical resection, radiofrequency ablation and liver transplantation are considered the cornerstones of curative therapy, while for patients with more advanced HCC recommended options include sorafenib and trans-arterial chemo-embolization. A multidisciplinary team, consisting of hepatologists, surgeons, radiologists, oncologists and pathologists, is fundamental for a correct management. In this paper, we review the diagnostic and therapeutic management of HCC, with a focus on the most recent evidences and recommendations from guidelines. PMID:26576088

1999-07-17

In two women aged 76 and 29 years, who presented with cholangitis and small ductus choledochus calculi and with painless icterus respectively, endoscopic retrograde cholangiopancreatography (ERCP) was carried out with papillotomy. Both developed a duodenal perforation which, however, could not be localized. The first patient eventually died, the second recovered after prolonged hospitalization. A third patient, a 53-year-old man, developed abdominal pain and fever four days after laparoscopic cholecystectomy. ERCP was planned, but in the meantime the patient showed signs of recovery. The ERCP was carried out nevertheless. It failed and the patient suffered a prolonged recovery with necrotizing pancreatitis and multiple operations necessitating a temporary colostoma. In all three patients the endoscopic procedure was performed routinely without strict individualized indication. ERCP and papillotomy may be relatively safe procedures, but it should always be considered whether they will really serve the patient.

Forty-five jaundiced patients with confirmed pancreatico-biliary diseases were studied to determine the value of body imaging in the differential diagnosis of jaundice. In this study, body imaging included five tests, which were US, CT, ERCP, PTC and RI. The results indicate that each to these five tests is useful and highly accurate in differentiating between obstructive and nonobstructive jaundice (about 90%). The site of obstruction was delineated in 91.3%, 90.9%, 82.5%, 66.7% and 50% by PTC, ERCP, CT, US and RI, respectively. ERCP, PTC, CT, US and RI helped determine the etiology of jaundice in 79.5%, 65.2%, 57.5%, 50% and 0%, respectively. ERCP and US were highly accurate in establishing the diagnosis of resectable pancreatico-biliary cancer with obstructive jaundice. On the basis of these results, we propose a diagnostic approach to obstructive jaundice as in Table 5. (author)

Full Text Available Background. The aim of this population-based study was to describe characteristics of patients with liver cirrhosis undergoing cholecystectomy and evaluate the risk for perioperative and postoperative complications during the 30-day postoperative period. Method. All laparoscopic and open cholecystectomy procedures registered between 2006 and 2011 in the Swedish Registry for Gallstone Surgery and ERCP (GallRiks were included. Patients with liver cirrhosis were identified by linking data to the Swedish National Patient Registry (NPR. Results. Of 62,488 patients undergoing cholecystectomy, 77 (0.12% had cirrhosis, of which 29 patients (37.7% had decompensated cirrhosis. Patients with cirrhosis were older and had more often gallstone complications at the time for surgery. Postoperative complications were registered in 13 (16.9% patients with liver cirrhosis and in 5,738 (9.2% patients in the noncirrhotic group (P1 day (OR = 2.3, CI 1.11–4.84, P<0.05 than noncirrhotic patients. Conclusion. Patients with cirrhosis undergoing cholecystectomy have a higher incidence of postoperative complications than patients without cirrhosis. However, cholecystectomy is safe and if presented with adequate indication, surgery should not be delayed due to fears of surgical complications.

There is a growing concern about the therapeutic equivalence of the generic tacrolimus formulation (GEN Tacrolimus) to the reference tacrolimus (REF Tacrolimus) in solid organ transplantation. A prospective, randomized study of 126 de novo renal transplant patients was conducted to compare the efficacy, safety and pharmacokinetic (PK) profiles between GEN tacrolimus (n = 63) and REF tacrolimus (n = 63). The PK of tacrolimus was evaluated on Day 10 and 6 months under steady-state condition. Crossover study was carried out in 66 patients at 6 months. On Day 10, 117 patients completed PK profiles (54 GEN tacrolimus and 63 REF tacrolimus) and GEN tacrolimus showed comparable C(0) (9.8 ± 2.5 versus 9.7 ± 3.0 ng/mL, P = 0.80) but significantly higher dose-normalized C(max) (309.1 ± 191.9 versus 192.5 ± 95.2 ng/mL/mg/kg, P PK profiles evaluated at 9 months showed that generic substitution also resulted in an 'early and high C(max)'. Efficacy and safety data were comparable over the 9-month study period. Therapeutic equivalence and the PK of GEN tacrolimus should be evaluated in patients undergoing de novo renal transplantation.

Endoscopic retrograde cholangiopancreatography (ERCP) is a diagnostic method and treatment approach for biliary diseases. However, biliary cannulation can be difficult in some cases. We performed ERCP in a 97-year-old woman with abdominal pain resulting from acute cholangitis caused by choledocholithiasis and observed difficult biliary cannulation. Eventually, the patient was successfully treated with the rendezvous technique. We could not cannulate the biliary duct during ERCP twice. Therefore, we placed a percutaneous transhepatic gallbladder drainage (PTGBD) tube without intrahepatic dilation. The rendezvous technique was performed using the PTGBD tube. The patient did not experience pancreatitis or perforation.

Full Text Available Background/Aims Biliary stone disease is one of the most common conditions leading to hospitalization. In addition to endoscopic retrograde cholangiopancreatography (ERCP, endoscopic ultrasonography (EUS and magnetic resonance cholangiopancreatography (MRCP are required in diagnosing choledocholithiasis. This study aimed to compare the sensitivity and specificity of EUS and MRCP against ERCP in diagnosing choledocholithiasis. Methods This retrospective study was conducted after prospective collection of data involving 62 suspected choledocholithiasis patients who underwent ERCP from June 2013 to August 2014. Patients were divided into two groups. The first group (31 patients underwent EUS and the second group (31 patients underwent MRCP. Then, ERCP was performed in both groups. Sensitivity, specificity, and diagnostic accuracy of EUS and MRCP were determined by comparing them to ERCP, which is the gold standard. Results The male to female ratio was 3:2. The mean ages were 47.25 years in the first group and 52.9 years in the second group. Sensitivity, specificity, accuracy, positive predictive value, and negative predictive value for EUS were 96%, 57%, 87%, 88%, and 80% respectively, and for MRCP were 81%, 40%, 68%, 74%, and 50%, respectively. Conclusions EUS is a better diagnostic tool than MRCP for diagnosing choledocholithiasis.

Full Text Available Objective : to evaluate the epidemiological variables and diagnostic and therapeutic modalities related to hepatic trauma patients undergoing laparotomy in a public referral hospital in the metropolitan region of Vitória-ES. Methods : we conducted a retrospective study, reviewing charts of trauma patients with liver injuries, whether isolated or in association with other organs, who underwent exploratory laparotomy, from January 2011 to December 2013. Results : We studied 392 patients, 107 of these with liver injury. The male: female ratio was 6.6 : 1 and the mean age was 30.12 years. Penetrating liver trauma occurred in 78.5% of patients, mostly with firearms. Associated injuries occurred in 86% of cases and intra-abdominal injuries were more common in penetrating trauma (p <0.01. The most commonly used operative technique was hepatorrhaphy and damage control surgery was applied in 6.5% of patients. The average amounts of blood products used were 6.07 units of packed red blood cells and 3.01 units of fresh frozen plasma. The incidence of postoperative complications was 29.9%, the most frequent being infectious, including pneumonia, peritonitis and intra-abdominal abscess. The survival rate of patients suffering from blunt trauma was 60%, and penetrating trauma, 87.5% (p <0.05. Conclusion : despite technological advances in diagnosis and treatment, mortality rates in liver trauma remain high, especially in patients suffering from blunt trauma in relation to penetrating one.

To identify the therapeutic regimens used at discharge in patients receiving oral anticoagulant therapy (OAT) who undergo stenting percutaneous coronary intervention and stent implantation (PCI-S), and to assess the safety and efficacy associated with different therapeutic regimens according to thromboembolic risk. A prospective multicentre registry. In hospital, after discharge and follow-up by telephone call. 405 patients (328 male/77 female; mean (SD) age 71 (9) years) receiving OAT who underwent PCI-S between November 2003 and June 2006 from nine catheterisation laboratories of tertiary care teaching hospitals in Spain and one in the United Kingdom were included. Three therapeutic regimens were identified at discharge: triple therapy (TT) -- that is, any anticoagulant (AC) plus double antiplatelet therapy (DAT; 278 patients (68.6%); AC and a single antiplatelet (AC+AT; 46 (11.4%)) and DAT only (81 (20%)). At 6 months, patients receiving TT showed the greatest rate of bleeding events. No patients receiving DAT at low thromboembolic risk presented a bleeding event (14.8% receiving TT, 11.8% receiving AC+AT and 0% receiving DAT, p = 0.033) or cardiovascular event (6.7% receiving TT, 0% receiving AC+AT and 0% receiving DAT, p = 0.126). The combination of AC+AT showed the worst rate of adverse events in the whole cohort, especially in patients at moderate-high thromboembolic risk. In patients receiving OAT, TT was the most commonly used regimen after PCI-S. DAT was associated with the lowest rate of bleeding events and a similar efficacy to TT in patients at low thromboembolic risk. TT should probably be restricted to patients at moderate-high thromboembolic risk.

Despite the effectiveness of endoscopic retrograde cholangiopancreatography (ERCP) for the treatment of choledocholithiasis, various complications have been described. We herein report the first case of prolonged post-ERCP jaundice due to toxicity of the contrast agent Iobitridol (®XENETIX, Guerbet, Roissy CdG Cedex, France) in a patient who underwent ERCP with sphincterectomy and common bile duct stone removal. While clinical improvement and normalization of aminotransferases and cholestatic enzymes after the procedure, an unexplained increase of direct bilirubin was noticed. A second ERCP was performed one week later, excluding possible remaining choledocholithiasis. Nevertheless, serum direct bilirubin increased further up to 15 mg/dL. Other potential causes of direct hyperbilirubinemia were ruled out and patient's liver biopsy was compatible with drug-induced liver toxicity. Additionally, the cause-result time connection between the use of Iobitridol and bilirubin increase indicated the possibility of a toxic effect related to the repeated use of the particular contrast agent. Iobitridol, a contrast agent, can induce prolonged direct hyperbilirubinemia.

Hospital de Quemados del Gobierno de la Ciudad de Buenos Aires (Burn Center) is one of the reference hospitals of the Medical Radiological Emergency Response Network of Argentina. In the frame of an agreement between the Burn Center and the Nuclear Regulatory Authority of Argentina, a research project for an approach based on diagnosis and therapy of cutaneous radiation induced lesions is in progress. Individual radiosensitivity assessment was conducted in patients included in this research protocol that showed acute and/or late cutaneous reactions with grades 3 and 4 of the Toxicity criteria of the Radiation Therapy Oncology Group (RTOG) and the European organization for research and treatment of cancer (EORTC). DNA repair capacity and its kinetics were evaluated in human peripheral blood lymphocytes using alkaline comet assay and micronucleus test. In this paper, two representative cases, in which the research protocol was applied, are presented. Therapeutic response and its correlation with radiosensitivity test results are described. Case 1: female patient undergoing external radiotherapy for invasive ductal breast cancer that presented acute cutaneous radiotoxicity, grade 3 (confluent moist epithelitis, )that led to treatment break. Case 2: male patient undergoing coronary angioplasty (interventional radiology), which developed late cutaneous radiotoxicity, grade 4 (ulceration at the dorsal region). Patients were treated with: topic administration of trolamine and silver sulfadiazine with lidocaine, associated with systemic administration of pentoxiphiline and anti-oxidants. The therapeutic response was evaluated through clinical follow-up, serial photographic record and complementary tests (tele thermography and high frequency ultrasonography). Case 1 response was positive (favorable) with early local recovery and complete remission of signs and symptoms after 5 months. Both MN frequencies and comet assay showed values compatible with normal radiosensitivity

The therapeutic function of play has been investigated in relation to recognized stressors such as hospitalization, illness and medical treatments for ill children. While medical treatments in the past 30 years have improved survival rates, children's psychological experiences and quality of life during and after their illness have received limited attention. The present study investigated the therapeutic effects of play on 3- to 5-year-old children with leukaemia compared with a control group of healthy children. The participants with leukaemia (n = 11) were from the external oncology clinic of an urban children's hospital; control children (n = 11) attended a day care centre. Measures included children's experience of stress, social and cognitive play behaviours, and daily mood. A series of manova revealed that the children with leukaemia, compared with the control children, engaged in (a) significantly fewer total play behaviours, and in particular less (b) parallel, (c) group and (d) dramatic play. Pearson correlations revealed significant relationships between reports of 'being happy' and play only for children with leukaemia. Quantitative and qualitative analyses revealed a pattern of repetitive play activities week after week for children with leukaemia, but not controls. Findings are discussed in light of the theoretical and practical implications for children undergoing treatment for leukaemia.

Low-dose dextromethorphan (DM) might have anti-inflammatory and neurotrophic effects mechanistically remote from an NMDA receptor. In a randomized, double-blind, controlled 12 week study, we investigated whether add-on dextromethorphan reduced cytokine levels and benefitted opioid-dependent patients undergoing methadone maintenance therapy (MMT). Patients were randomly assigned to a group: DM60 (60mg/day dextromethorphan; n = 65), DM120 (120mg/day dextromethorphan; n = 65), or placebo (n = 66). Primary outcomes were the methadone dose required, plasma morphine level, and retention in treatment. Plasma tumor necrosis factor (TNF)-α, C-reactive protein, interleukin (IL)-6, IL-8, transforming growth factor-β1, and brain-derived neurotrophic factor (BDNF) levels were examined during weeks 0, 1, 4, 8, and 12. Multiple linear regressions with generalized estimating equation methods were used to examine the therapeutic effect. After 12 weeks, the DM60 group had significantly longer treatment retention and lower plasma morphine levels than did the placebo group. Plasma TNF-α was significantly decreased in the DM60 group compared to the placebo group. However, changes in plasma cytokine levels, BDNF levels, and the methadone dose required in the three groups were not significantly different. We provide evidence-decreased concomitant heroin use-of low-dose add-on DM's efficacy for treating opioid-dependent patients undergoing MMT. © The Author 2015.

Full Text Available Abstract Background Cancer is one of the major health issues worldwide. An increasing number of cancer patients are offered treatment with surgery, chemotherapy and radiotherapy. Traditional Chinese medicine (TCM is one of the most common complementary therapies offered to cancer patients in Taiwan. We designed a randomized, double-blind, placebo-controlled clinical trial to evaluate the efficacy of TCM in patients with cancer. Methods/design In this study, inclusion criteria are postoperative patients with histologically confirmed cancer within 3 years who are undergoing chemotherapy or radiotherapy, more than 18 years old, have given signed informed consent, have the ability to read Chinese, and the ability for oral intake. Exclusion criteria include being pregnant, breast feeding, having completed chemotherapy or radiotherapy, brain metastasis with Eastern Cooperative Oncology Group (ECOG performance status of two to four, delusion or hallucinations, acute infection, and have received medications under other clinical trials. The patients were separated into an intervention group (Shen-Mai-San, SMS and a placebo group for four weeks using a randomized, double-blind procedure.

AIM: To evaluate the effect of cholecystokinin (CCK) during extracorporeal shockwave lithotripsy (ESWL) in the clearance of common bile duct (CBD) stones in endoscopic retrograde cholangiopancreatography (ERCP). METHODS: Between January 2007 and September 2012, patients with large CBD stones who were treated with ESWL and ERCP were identified retrospectively. Patients were randomized in equal numbers to cholecystokinin (CCK) and no CCK groups. For each CCK case, a dose (3 ng/kg per min for 10 min) of sulfated octapeptide of CCK-8 was administered intravenously near the beginning of ESWL. ERCP was performed 4 h after a session of ESWL. The clearance rate of the CBD was assessed between the two groups. RESULTS: A total of 148 consecutive cases (CCK group: 74, no CCK group: 74) were tallied. Overall there were 234 ESWLs and 228 ERCPs in the 148 cases. The use of CCK showed a significantly higher rate of successful stone removal in the first ESWL/ERCP procedure (71.6% vs 55.4%, P = 0.035), but resulted in similar outcomes in the second (42.8% vs 39.4%) and third (41.7% vs 40.0%) sessions, as well as total stone clearance (90.5% vs 83.8%). The use of mechanical lithotripsy was reduced in the CCK group (6.8% vs 17.6%, P = 0.023), and extremely large stone (≥ 30 mm) removal was higher in the CCK group (72.7% vs 41.7%, P = 0.038). CONCLUSION: CCK during ESWL can aid with the clearance of CBD stones in the first ESWL/ERCP session. Mechanical lithotripsy usage was reduced and the extremely large stone (≥ 30 mm) clearance rate can be raised. PMID:25110439

Regulating Critical Period Plasticity: Insight from the Visual System to Fear Circuitry for Therapeutic Interventions

Directory of Open Access Journals (Sweden)

2013-11-01

Full Text Available Early temporary windows of heightened brain plasticity called critical periods developmentally sculpt neural circuits and contribute to adult behavior. Regulatory mechanisms of visual cortex development –the preeminent model of experience-dependent critical period plasticity- actively limit adult plasticity and have proved fruitful therapeutic targets to reopen plasticity and rewire faulty visual system connections later in life. Interestingly, these molecular mechanisms have been implicated in the regulation of plasticity in other functions beyond vision. Applying mechanistic understandings of critical period plasticity in the visual cortex to fear circuitry may provide a conceptual framework for developing novel therapeutic tools to mitigate aberrant fear responses in post traumatic stress disorder. In this review, we turn to the model of experience-dependent visual plasticity to provide novel insights for the mechanisms regulating plasticity in the fear system. Fear circuitry, particularly fear memory erasure, also undergoes age-related changes in experience-dependent plasticity. We consider the contributions of molecular brakes that halt visual critical period plasticity to circuitry underlying fear memory erasure. A major molecular brake in the visual cortex, perineuronal net formation, recently has been identified in the development of fear systems that are resilient to fear memory erasure. The roles of other molecular brakes, myelin-related Nogo receptor signaling and Lynx family proteins– endogenous inhibitors for nicotinic acetylcholine receptor, are explored in the context of fear memory plasticity. Such fear plasticity regulators, including epigenetic effects, provide promising targets for therapeutic interventions.

Purpose: Ultrasound-guided trans perineal interstitial permanent prostate brachytherapy (TIPPB) is generally performed with either 103 Pd or 125 I. The use of 125 I for low Gleason score tumors and 103 Pd for higher Gleason scores has been suggested based on isotope dose rate and cell doubling time observed in in vitro studies. While many centers follow these isotope selection criteria, other centers have elected to use only a single isotope, regardless of Gleason score. No clinical data have been published comparing these isotopes. This study was undertaken to compare outcomes between 125 I and 103 Pd in a matched pair analysis for patients undergoing prostate brachytherapy. Methods and Materials: Six hundred forty-eight consecutively treated patients with clinically confined prostate cancer underwent TIPPB between June 1992 and February 1997. Five hundred thirty-two patients underwent TIPPB alone, whereas 116 received pelvic external beam irradiation and TIPPB. Ninety-three patients received androgen deprivation therapy prior to TIPPB. The prescribed doses for TIPPB were 160 Gy for 125 I (pre-TG43) and 120 Gy for 103 Pd. Patients treated with combination therapy received 41.4 or 45 Gy (1.8 Gy/fraction) external beam irradiation followed by a 3- to 5-week break and then received either a 120-Gy 125 I or a 90-Gy 103 Pd implant. Until November 1994, all patients underwent an 125 I implant after which the isotope selection was based on either Gleason score (Gleason score 2-5: 125 I; Gleason 5-8: 103 Pd) or isotope availability. A matched pair analysis was performed to assess any difference between isotopes. Two hundred twenty-two patients were matched according to Gleason score, prostate-specific antigen (PSA), and stage. PSA relapse-free survival (PSA-RFS) was calculated based on the American Society for Therapeutic Radiology and Oncology (ASTRO) Consensus Group definition of failure. Kaplan-Meier actuarial survival curves were compared to assess differences in

Therapeutic Nanodevices

Lee, Stephen; Ruegsegger, Mark; Barnes, Philip; Smith, Bryan; Ferrari, Mauro

Therapeutic nanotechnology offers minimally invasive therapies with high densities of function concentrated in small volumes, features that may reduce patient morbidity and mortality. Unlike other areas of nanotechnology, novel physical properties associated with nanoscale dimensionality are not the raison d'être of therapeutic nanotechnology, whereas the aggregation of multiple biochemical (or comparably precise) functions into controlled nanoarchitectures is. Multifunctionality is a hallmark of emerging nanotherapeutic devices, and multifunctionality can allow nanotherapeutic devices to perform multistep work processes, with each functional component contributing to one or more nanodevice subroutine such that, in aggregate, subroutines sum to a cogent work process. Cannonical nanotherapeutic subroutines include tethering (targeting) to sites of disease, dispensing measured doses of drug (or bioactive compound), detection of residual disease after therapy and communication with an external clinician/operator. Emerging nanotherapeutics thus blur the boundaries between medical devices and traditional pharmaceuticals. Assembly of therapeutic nanodevices generally exploits either (bio)material self-assembly properties or chemoselective bioconjugation techniques, or both. Given the complexity, composition, and the necessity for their tight chemical and structural definition inherent in the nature of nanotherapeutics, their cost of goods (COGs) might exceed that of (already expensive) biologics. Early therapeutic nanodevices will likely be applied to disease states which exhibit significant unmet patient need (cancer and cardiovascular disease), while application to other disease states well-served by conventional therapy may await perfection of nanotherapeutic design and assembly protocols.

To identify trends regarding therapeutic approaches to metformin administration in patients undergoing in vitro fertilization (IVF) treatment worldwide. A retrospective evaluation utilizing the results of a web-based survey, IVFWorldwide ( www.IVF-worldwide.com/ ), was performed. Responses from 101 centers performing a total of 50,800 annual IVF cycles was performed. Of these cycles, 10.4% (n = 5,260) reported metformin use during IVF cycles. Indications for metformin use in IVF cycles included polycystic ovary syndrome (PCOS) patients who were habitual abortions (67%), had prior poor egg quality (61%), had high serum insulin levels (56%). Less reported was PCOS with obesity/anvoulation (29%), PCOS with multiple manifestations (23%) and glucose intolerance and insulin resistance (23%). Over half of cycles (54%) treated patients with metformin up to 3 months prior to starting IVF. A majority (82%) of IVF cycles utilized 1500-2000 mg/day of metformin. A nearly equal percentage of centers continued metformin up to a positive β-HCG test (35%) or to 12 weeks gestation (33%). 70% of IVF cycles reported increased pregnancy rates and decreased miscarriage rates due to the use of metformin. 75% reported the data in the literature is not sufficient for reaching a definitive conclusion concerning metformin treatment in patients undergoing IVF. While metformin is used worldwide as an adjunct to standard IVF protocols, there is much variation in its use and the majority of centers report lack of evidence supporting its use.

Idiopathic recurrent pancreatitis remains a clinical challenge. Intraductal ultrasonography in the management of idiopathic recurrent pancreatitis may be a new strategy for undetermined causes after initial diagnostic approaches, including endoscopic retrograde cholangio-pancreatography (ERCP). However, no definite cause after ERCP should be defined under optimal settings and with experienced technique.

A limited number of endoscopic retrograde cholangiopancreatography (ERCP) accessories are compatible with the conventional single-balloon enteroscope (SBE) because of the latter's dimensions. The aim of the present study was to assess the utility of a prototype SBE that has a shorter working length and a wider channel than the conventional SBE. ERCP procedures carried out between January 2012 and July 2013 using the short SBE prototype were reconstructions such as Billroth II (B-II), post-gastrectomy with Roux-en-Y (RY-G), and post-choledochojejunostomy with Roux-en-Y (RY-CJ). We retrospectively analyzed the rate of reaching the blind end of the intestine, the diagnostic success rate, the interventional success rate, and the frequency of related complications. Twenty-seven ERCP procedures on 18 patients analyzed comprised two B-II, 15 RY-G, and 10 RY-CJ reconstructions. With a mean procedure time of 56 min (range 40-150 min), the rate of reaching the blind end, the diagnostic success rate, and the interventional success rate were 24/27 (89%), 20/27 (74%), and 19/27 (70%), respectively. There were no major ERCP-related complications in any patient. The prototype short-type SBE appears safe and effective for use in ERCP, and is compatible with conventional endoscopy accessories. © 2014 The Authors.

Nuclear transfer and therapeutic cloning have widespread and attractive prospects in animal agriculture and biomedical applications. We reviewed that the quality of oocytes and nuclear reprogramming of somatic donor cells were the main reasons of the common abnormalities in cloned animals and the low efficiency of cloning and showed the problems and outlets in therapeutic cloning, such as some basic problems in nuclear transfer affected clinical applications of therapeutic cloning. Study on isolation and culture of nuclear transfer embryonic stem (ntES) cells and specific differentiation of ntES cells into important functional cells should be emphasized and could enhance the efficiency. Adult stem cells could help to cure some great diseases, but could not replace therapeutic cloning. Ethics also impeded the development of therapeutic cloning. It is necessary to improve many techniques and reinforce the research of some basic theories, then somatic nuclear transfer and therapeutic cloning may apply to agriculture reproduction and benefit to human life better.

2018-01-29

This review aims to emphasize how therapeutic inertia, the failure of clinicians to intensify treatment when blood pressure rises or remains above therapeutic goals, contributes to suboptimal blood pressure control in hypertensive populations. Studies reveal that the therapeutic inertia is quite common and contributes to suboptimal blood pressure control. Quality improvement programs and standardized approaches to support antihypertensive treatment intensification are ways to combat therapeutic inertia. Furthermore, programs that utilize non-physician medical professionals such as pharmacists and nurses demonstrate promise in mitigating the effects of this important problem. Therapeutic inertia impedes antihypertensive management and requires a broad effort to reduce its effects. There is an ongoing need for renewed focus and research in this area to improve hypertension control.

Therapeutic hypothermia improves the survival and neurodevelopmental outcome of infants with newborn encephalopathy of a hypoxic-ischemic origin. The NICHD Neonatal Research Network (NRN) Whole Body Cooling trial used the Cincinnati Sub-Zero Blanketrol II to achieve therapeutic hypothermia. The Blanketrol III is now available and provides additional cooling modes that may result in better temperature control. This report is a retrospective comparison of infants undergoing hypothermia using two different cooling modes of the Blanketrol device. Infants from the NRN trial were cooled with the Blanketrol II using the Automatic control mode (B2 cohort) and were compared with infants from two new NRN centers that adopted the NRN protocol and used the Blanketrol III in a gradient mode (B3 cohort). The primary outcome was the percent time the esophageal temperature stayed between 33°C and 34°C (target 33.5°C) during maintenance of hypothermia. Cohorts had similar birth weight, gestational age, and level of encephalopathy at the initiation of therapy. Baseline esophageal temperature differed between groups (36.6°C ± 1.0°C for B2 vs. 33.9°C ± 1.2°C for B3, p<0.0001) reflecting the practice of passive cooling during transport prior to initiation of active device cooling in the B3 cohort. This difference prevented comparison of temperatures during induction of hypothermia. During maintenance of hypothermia the mean and standard deviation of the percent time between 33°C and 34°C was similar for B2 compared to B3 cohorts (94.8% ± 0.1% vs. 95.8% ± 0.1%, respectively). Both the automatic and gradient control modes of the Blanketrol devices appear comparable in maintaining esophageal temperature within the target range during maintenance of therapeutic hypothermia.

The international normalized ratio (INR as seen in a population of patients with atrial fibrillation and cerebral infarction undergoing long-term treatment with vitamin K antagonists

Full Text Available It is estimated that nearly 20% of all cerebral infarctions in the total population are the result of a complication of atrial fibrillation (AF. While oral anticoagulation with vitamin K antagonists (AVKs substantially reduces this risk, this requires regular monitoring of the international normalized ratio (INR in order to achieve therapeutic levels (2,0-3,0. The aim of this study was to evaluate a group at high risk of cerebral infarction, among patients with AF undergoing long-term treatment with VKAs, taking into account the significance of therapeutic INR values. The analysed group consisted of 90 acute ischaemic stroke patients with paroxysmal or chronic “non-valvular” AF, receiving treatment with VKAs. As a result of the study, therapeutic INR values (≥ 2 were seen in thirty-five of these individuals (38,8%, while 55 (61,2% showed non-therapeutic INR values. Moreover, there were no differences in demographics, vascular risk factors, biochemical and morphological blood parameters, mean CHA2DS2-VASc score and TOAST classification between either of the two groups. Furthermore, no additional factor that would increase their risk of cerebral infarction during the adequate treatment with VKAs was found. However, patients with non-therapeutic INR values had a statistically significantly higher frequency of concomitant moderate pathology of the bicuspid valve, p<0.05. Hence, a lack of proper control of INR can proved to be particularly dangerous for this subgroup of patients. Hence, this is a group with an elevated risk of cerebral infarction and therefore requires special oversight of VKA treatment or NOA treatment.

2016-02-01

Cancer cachexia is a debilitating metabolic syndrome accounting for fatigue, an impairment of normal activities, loss of muscle mass associated with body weight loss eventually leading to death in majority of patients with advanced disease. Cachexia patients undergoing skeletal muscle atrophy show consistent activation of the SCF ubiquitin ligase (F-BOX) family member Atrogin-1 (also known as MAFBx/FBXO32) alongside the activation of the muscle ring finger protein1 (MuRF1). Other lesser known F-BOX family members are also emerging as key players supporting muscle wasting pathways. Recent work highlights a spectrum of different cancer signaling mechanisms impacting F-BOX family members that feed forward muscle atrophy related genes during cachexia. These novel players provide unique opportunities to block cachexia induced skeletal muscle atrophy by therapeutically targeting the SCF protein ligases. Conversely, strategies that induce the production of proteins may be helpful to counter the effects of these F-BOX proteins. Through this review, we bring forward some novel targets that promote atrogin-1 signaling in cachexia and muscle wasting and highlight newer therapeutic opportunities that can help in the better management of patients with this devastating and fatal disorder.

2005-01-01

Purpose: To evaluate the accuracy of MRCP in diagnosing choledocholithiasis considering Endoscopic Retrograde Cholangiopancreatography (ERCP) as the gold standard. To compare the results achieved during the first two years of use (1999-2000) of Magnetic Resonance Cholangiopancreatography (MRCP) in patients with suspected choledocholithiasis with those achieved during the following two years (2001-2002) in order to establish the repeatability and objectivity of MRCP results. Materials and methods: One hundred and seventy consecutive patients underwent MRCP followed by ERCP within 72 h. In 22/170 (13%) patients ERCP was unsuccessful for different reasons. MRCP was performed using a 1.5 T magnet with both multi-slice HASTE sequences and thick-slice projection technique. Choledocholithiasis was diagnosed in the presence of signal void images in the dependent portion of the duct surrounded by hyperintense bile and detected at least in two projections. The MRCP results, read independently from the ERCP results, were compared in two different and subsequent periods. Results: ERCP confirmed choledocholithiasis in 87 patients. In these cases the results of MRCP were the following: 78 true positives, 53 true negatives, 7 false positives, and 9 false negatives. The sensitivity, specificity and accuracy were 90%, 88% and 89%, respectively. After the exclusion of stones with diameters smaller than 6 mm, the sensitivity, specificity and accuracy were 100%, 99% and 99%, respectively. MRCP accuracy was related to the size of the stones. There was no significant statistical difference between the results obtained in the first two-year period and those obtained in the second period. Conclusions: MRCP i sufficiently accurate to replace ERCP in patients with suspected choledocholithiasis. The results are related to the size of stones. The use of well-defined radiological signs allows good diagnostic accuracy independent of the learning curve [it

Human Factor in Therapeutic Relationship

Full Text Available herapeutic relationship is a professional relationship that has been structured based on theoretical props. This relationship is a complicated, wide and unique relationship which develops between two people, where both sides' personality and attitudes inevitably interfere. Therapist-client relationship experienced through transference and counter transference, especially in psychodynamic approaches, is accepted as the main aspect of therapeutic process. However, the approaches without dynamic/deterministic tendency also take therapist-client relationship into account seriously and stress uniqueness of interaction between two people. Being a person and a human naturally sometimes may negatively influence the relationship between the therapist and client and result in a relationship going out of the theoretical frame at times. As effective components of a therapeutic process, the factors that stem from being human include the unique personalities of the therapist and the client, their values and their attitude either made consciously or subconsciously. Literature has shown that the human-related factors are too effective to be denied in therapeutic relationship process. Ethical and theoretical knowledge can be inefficient to prevent the negative effects of these factors in therapeutic process at which point a deep insight and supervision would have a critical role in continuing an acceptable therapeutic relationship. This review is focused on the reflection of some therapeutic factors resulting from being human and development of counter transference onto the therapeutic process.

Therapeutic antibodies (IgG-type) contain several post-translational modifications (PTMs) whereby introducing a large heterogeneity, both structural and functional, into this class of therapeutics. Of these modifications, glycosylation in the fragment crystallizable (Fc) region is the most heterogeneous PTM, which can affect the stability of the molecule and interactions with Fc-receptors in vivo. Hence, the glycoform distribution can affect the mode of action and have implications for bioactivity, safety and efficacy of the drug. Main topics of the manuscript include: What factors influence the (Fc) glycan pattern in therapeutic antibodies and how can these glycans be characterized? How does structure of the Fc-glycan relate to function and what methods are available to characterize those functions? Although heterogeneous in their scope, the different sections are intended to combine current knowledge on structure-function correlations of IgG glycan structures with regard to Fc (effector) functions, as well as basic aspects and methodologies for their assessment.

Pierce, Robin L

2015-01-01

Translational nanomedicine occurs only through the successful integration of multiple inputs and iterative modifications. The therapeutic window plays a pivotal role in the trajectory of translational nanomedicine. Often defined in terms of the range of dosage for safe and effective therapeutic effect, a second definition of the therapeutic window refers to the often narrow temporal window in which a therapeutic effect can be obtained. Expanding the second definition to explicitly include the spatial dimension, this article explores aspects of the therapeutic spaces created by nanomedicine that shift the traditional dimensions of symptom, sign and pathology. This article analyzes three aspects of the therapeutic window in nanomedicine - temporal, spatial and manner of construction and their impact on the dimensions of modern medicine.

Therapeutic enhancement: nursing intervention category for patients diagnosed with Readiness for Therapeutic Regimen Management.

Kelly, Cynthia W

To present a new nursing intervention category called therapeutic enhancement. Fewer than half of North Americans follow their physician's recommendations for diet and exercise, even when such are crucial to their health or recovery. It is imperative that nurses consider new ways to promote healthy behaviours. Therapeutic enhancement is intended to provide such a fresh approach. Traditional intervention techniques focusing on education, contracts, social support and more frequent interaction with physicians appear not to be effective when used alone. Successful strategies have been multidisciplinary; and have included interventions by professional nurses who assist patients to understand their disease and the disease process and that helps them to develop disease-management and self-management skills. Therapeutic enhancement incorporates The Stages of Change Theory, Commitment to Health Theory, Motivational Interviewing techniques and instrumentation specifically designed for process evaluation of health-promoting interventions. This is a critical review of approaches that, heretofore, have not been synthesised in a single published article. Based on the commonly used Stages of Change model, therapeutic enhancement is useful for patients who are at the action stage of change. Using therapeutic enhancement as well as therapeutic strategies identified in Stages of Change Theory, such as contingency management, helping relationships, counterconditioning, stimulus control and Motivational Interviewing techniques, nursing professionals can significantly increase the chances of patients moving from action to the maintenance stage of change for a specific health behaviour. Using the nursing intervention category, therapeutic enhancement can increase caregivers' success in helping patients maintain healthy behaviours.

The therapeutic relationship after psychiatric admission.

LENUS (Irish Health Repository)

Roche, Eric

2014-03-01

The therapeutic relationship is one of the most central and important factors in the treatment of mental health disorders. A better therapeutic relationship is associated with service engagement, medication adherence, and satisfaction with services. This study aimed to compare the demographic and clinical factors associated with the therapeutic relationship in voluntarily and involuntarily admitted psychiatric service users. We found that individuals who had been admitted involuntarily, who had a diagnosis of a psychotic disorder, and who reported higher levels of perceived pressures on admission were more likely to have a poorer therapeutic relationship with their consultant psychiatrist. Greater levels of insight and treatment satisfaction, together with higher levels of procedural justice experienced on admission, were associated with a better therapeutic relationship. We found that the level of perceived coercion on admission was not related to the therapeutic relationship. Targeted interventions to improve the therapeutic relationship, particularly for involuntarily admitted service users, are discussed.

Although results of cardiac surgery are improving, octogenarians have a higher procedure-related mortality and more complications with increased length of stay in ICU. Consequently, careful evaluation of perioperative risk seems necessary. The aims of our study were to assess and compare the performances of EuroSCORE and CARE score in the prediction of perioperative mortality among octogenarians undergoing aortic valve replacement for aortic stenosis and to compare these predictive performances with those obtained in younger patients. This retrospective study included all consecutive patients undergoing cardiac surgery in our institution between November 2005 and December 2007. For each patient, risk assessment for mortality was performed using logistic EuroSCORE, additive EuroSCORE and CARE score. The main outcome measure was early postoperative mortality. Predictive performances of these scores were assessed by calibration and discrimination using goodness-of-fit test and area under the receiver operating characteristic curve, respectively. During this 2-year period, we studied 2117 patients, among whom 134/211 octogenarians and 335/1906 nonoctogenarians underwent an aortic valve replacement for aortic stenosis. When considering patients with aortic stenosis, discrimination was poor in octogenarians and the difference from nonoctogenarians was significant for each score (0.58, 0.59 and 0.56 vs. 0.82, 0.81 and 0.77 for additive EuroSCORE, logistic EuroSCORE and CARE score in octogenarians and nonoctogenarians, respectively, P performances of these scores are poor in octogenarians undergoing cardiac surgery, especially aortic valve replacement. Risk assessment and therapeutic decisions in octogenarians should not be made with these scoring systems alone.

[Health security--GMOs in therapeutics].

Science.gov (United States)

Trouvin, J-H

2003-03-01

The recent progress in human therapeutics has been made possible thanks to molecular biology and its use in producing proteins having the same sequence and structure as that of human proteins. The use of GMOs allows production of proteins with high added value in therapeutics, which are of satisfactory quality. GMOs may also be directly administered to patients as gene therapy vectors. However, the use of GMOs in therapeutics must take into consideration some risks, particularly those of microbiological contamination, of neo-antigenicity as well as environmental risks with regard to the way of use of the GMO. Nevertheless, those risks are taken in due consideration in the development of these new medicinal products; solutions have been found to allow their use in therapeutics with a very positive benefit/risk ratio. Medicinal products from biotechnology have enabled considerable therapeutic progress without compromising health security.

2005-01-01

A brief outline of stem cells, stem cell therapy and therapeutic cloning is given. The position of therapeutic cloning with regard to other embryonic manipulations - IVF-based reproduction, embryonic stem formation from IVF embryos and reproductive cloning - is indicated. The main ethically challenging stages in therapeutic cloning are considered to be the nuclear transfer process including the source of eggs for this and the destruction of an embryo to provide stem cells for therapeutic use. The extremely polarised nature of the debate regarding the status of an early human embryo is noted, and some potential alternative strategies for preparing immunocompatible pluripotent stem cells are indicated

Therapeutic cloning in the mouse

2003-01-01

Nuclear transfer technology can be applied to produce autologous differentiated cells for therapeutic purposes, a concept termed therapeutic cloning. Countless articles have been published on the ethics and politics of human therapeutic cloning, reflecting the high expectations from this new opportunity for rejuvenation of the aging or diseased body. Yet the research literature on therapeutic cloning, strictly speaking, is comprised of only four articles, all in the mouse. The efficiency of derivation of embryonic stem cell lines via nuclear transfer is remarkably consistent among these reports. However, the efficiency is so low that, in its present form, the concept is unlikely to become widespread in clinical practice. PMID:12949262

BACKGROUND: There is substantial variability in the perioperative administration of aspirin in patients undergoing noncardiac surgery, both among patients who are already on an aspirin regimen and among those who are not. METHODS: Using a 2-by-2 factorial trial design, we randomly assigned 10......,010 patients who were preparing to undergo noncardiac surgery and were at risk for vascular complications to receive aspirin or placebo and clonidine or placebo. The results of the aspirin trial are reported here. The patients were stratified according to whether they had not been taking aspirin before...... the study (initiation stratum, with 5628 patients) or they were already on an aspirin regimen (continuation stratum, with 4382 patients). Patients started taking aspirin (at a dose of 200 mg) or placebo just before surgery and continued it daily (at a dose of 100 mg) for 30 days in the initiation stratum...

We investigated whether colon-targeted delivery of PCT could enhance anti-colitic effects and how therapeutic enhancement occurred at the molecular level. Molecular effects of PCT were examined in human colon carcinoma cells and inflamed colons. The anti-colitic effects of PCT in a colon-targeted capsule (colon-targeted PCT were compared with PCT in a gelatin capsule (conventional PCT in a trinitrobenzene sulfonic acid-induced rat colitis model. Colon-targeted PCT elicited greatly enhanced recovery of the colonic inflammation. In HCT116 cells, PCT inhibited nuclear factor kappaB while activating anti-colitic transcription factors, nuclear factor-erythroid 2 (NF-E2 p45-related factor 2, and hypoxia-inducible factor-1. Colon-targeted PCT, but not conventional PCT, modulated production of the target gene products of the transcription factors in the inflamed colonic tissues. Rectal administration of PCT, which simulates the therapeutic action of colon-targeted PCT, also ameliorated rat colitis and reproduced the molecular effects in the inflamed colonic tissues. Colon-targeted delivery increased therapeutic efficacy of PCT against colitis, likely resulting from multitargeted effects exerted by colon-targeted PCT. The drug delivery technique may be useful for therapeutic optimization of anti-colitic lead compounds including natural products.

To analyze coping strategies used by children with cancer undergoing chemotherapy during hospitalization. This was an exploratory study to analyze qualitative data using an inductive thematic analysis. Semistructured interviews using puppets were conducted with 10 children with cancer, between 7 and 12 years old, who were hospitalized and undergoing chemotherapy. The coping strategies to deal with chemotherapy were: understanding the need for chemotherapy; finding relief for the chemotherapy's side effects and pain; seeking pleasure in nourishment; engaging in entertaining activities and having fun; keeping the hope of cure alive; and finding support in religion. Children with cancer undergoing chemotherapy need to cope with hospitalizations, pain, medication side effects, idle time, and uncertainty regarding the success of treatment. These challenges motivated children to develop their own coping strategies, which were effective while undergoing chemotherapy. By gaining knowledge and further understanding about valid coping strategies during chemotherapy treatment, health professionals can mobilize personal and material resources from the children, health teams, and institutions aiming to potentiate the use of these strategies to make treatments the least traumatic. © 2015 Sigma Theta Tau International.

[Cancer stem cells as the therapeutic target of tomorrow].

Hatina, Jiří

2017-02-01

The concept of hierarchical organization of tumour cell population, with cancer stem cells positioned at the apex of the cell hierarchy, can explain at least some crucial aspects of biological and clinical behaviour of cancer, like its propensity to relapse as well as the development of therapeutic resistance. The underlying biological properties of cancer stem cells are crucially dependent on various signals, inhibition of which provides an attractive opportunity to attack pharmacologically cancer stem cells. Currently, a lot of such stemness-inhibitors undergo various phases of clinical testing. Interestingly, numerous old drugs that are in routine use in human and veterinary medicine for non-oncological indications appear to be able to specifically target cancer stem cells as well. As cancer stem cells, at least for most tumours, represent usually only a minor tumour cell fraction, it is quite probable that the main focus of the clinical use of the stemness inhibitors would consist in their rational combinations with traditional anticancer treatment modalities. A highly important goal for the future research is to identify reliable and clinically applicable predictive markers that would allow to apply these novel anticancer drugs on the individual basis within the context of personalized medicine.

Mechanisms of protein misfolding: Novel therapeutic approaches to protein-misfolding diseases

Salahuddin, Parveen; Siddiqi, Mohammad Khursheed; Khan, Sanaullah; Abdelhameed, Ali Saber; Khan, Rizwan Hasan

2016-11-01

In protein misfolding, protein molecule acquires wrong tertiary structure, thereby induces protein misfolding diseases. Protein misfolding can occur through various mechanisms. For instance, changes in environmental conditions, oxidative stress, dominant negative mutations, error in post-translational modifications, increase in degradation rate and trafficking error. All of these factors cause protein misfolding thereby leading to diseases conditions. Both in vitro and in vivo observations suggest that partially unfolded or misfolded intermediates are particularly prone to aggregation. These partially misfolded intermediates aggregate via the interaction with the complementary intermediates and consequently enhance oligomers formation that grows into fibrils and proto-fibrils. The amyloid fibrils for example, accumulate in the brain and central nervous system (CNS) as amyloid deposits in the Parkinson's disease (PD), Alzheimer's disease (AD), Prion disease and Amylo lateral Sclerosis (ALS). Furthermore, tau protein shows intrinsically disorder conformation; therefore its interaction with microtubule is impaired and this protein undergoes aggregation. This is also underlying cause of Alzheimers and other neurodegenerative diseases. Treatment of such misfolding maladies is considered as one of the most important challenges of the 21st century. Currently, several treatments strategies have been and are being discovered. These therapeutic interventions partly reversed or prevented the pathological state. More recently, a new approach was discovered, which employs nanobodies that targets multisteps in fibril formation pathway that may possibly completely cure these misfolding diseases. Keeping the above views in mind in the current review, we have comprehensively discussed the different mechanisms underlying protein misfolding thereby leading to diseases conditions and their therapeutic interventions.

76 cases in which in the time between 1969 and 1974 coeliacographies were carried out and the diagnoses are clinically manifested were retrospectively analysed. The angiographic symptoms and the diagnostic results are compared to the literature. Following this, the diagnostic and therapeutic value in liver processes, paucreas processes, stomach tumours, gastrointestinal bleedings, traumas of the epigastric organs, catheter embolisation and stopping of acute, severe gastrointestinal bleedings are discussed. The value of angiography in comparison to laparoscopy, ERCP, sonography, and computerized tomography is discussed. At the end, the indication of angiography in diseases of the epigastric organs is summarized in two tables, distinguishing between absolute, relative, strongly restricted indications and no indication at all.

Sutaria, Dhruvitkumar S; Badawi, Mohamed; Phelps, Mitch A; Schmittgen, Thomas D

2017-05-01

Extracellular vesicles (EVs) represent a class of cell secreted organelles which naturally contain biomolecular cargo such as miRNA, mRNA and proteins. EVs mediate intercellular communication, enabling the transfer of functional nucleic acids from the cell of origin to the recipient cells. In addition, EVs make an attractive delivery vehicle for therapeutics owing to their increased stability in circulation, biocompatibility, low immunogenicity and toxicity profiles. EVs can also be engineered to display targeting moieties on their surfaces which enables targeting to desired tissues, organs or cells. While much has been learned on the role of EVs as cell communicators, the field of therapeutic EV application is currently under development. Critical to the future success of EV delivery system is the description of methods by which therapeutics can be successfully and efficiently loaded within the EVs. Two methods of loading of EVs with therapeutic cargo exist, endogenous and exogenous loading. We have therefore focused this review on describing the various published approaches for loading EVs with therapeutics.

To evaluate the impact of targeted agents in stage II-III rectal cancer undergoing neoadjuvant concurrent chemoradiation therapy (CCRT). A retrospective study was performed in 124 consecutive patients with clinically T 3 N 0-2 M 0 -staged rectal cancer incorporating targeted agents in CCRT. Pathologic complete response was detected in 34.2% (n=26) of bevacizumab+FOLFOX-treated patients (n=76), which was significantly higher (p=0.019, post-hoc statistical power =35.87%) than that (n=10, 20.8%) of the cetuximab+FOLFOX-treated patients (n=48). Patients receiving cetuximab+FOLFOX therapy tended to develop severe liver toxicity (91.7%, n=44 versus 17.1%, n=13, panalysis within bevacizumab+FOLFOX-treated patients with either wild-type (n=36) or mutant (n=40) K-ras status indicated K-ras status did not significantly influence the treatment outcomes. The addition of bevacizumab instead of cetuximab to FOLFOX in the neoadjuvant settings for T 3 N 0-2 M 0 -staged rectal cancer could induce a promising rate of pathologic complete response and lesser hepatotoxicity.

This is a prospective multicenter registry designed to evaluate the incidence of adverse cardiovascular events in Middle Eastern patients undergoing percutaneous coronary interventions (PCI). The registry was also designed to determine the predictors of poor outcomes in such patients. We enrolled 2426 consecutive patients who underwent PCI at 12 tertiary care centers in Jordan between January 2013 and February 2014. A case report form was used to record data prospectively at hospital admission, discharge, and 12 months of follow-up. Mean age was 56 ± 11 years, females comprised 21% of the study patients, 62% had hypertension, 53% were diabetics, and 57% were cigarette smokers. Most patients (77%) underwent PCI for acute coronary syndrome. In-hospital and 1-year mortality rates were 0.78% and 1.94%, respectively. Definite or probable stent thrombosis occurred in 9 patients (0.37%) during hospitalization and in 47 (1.94%) at 1 year. Rates of target vessel repeat PCI and coronary artery bypass graft surgery at 1 year were 3.4% and 0.6%, respectively. The multivariate analysis revealed that cardiogenic shock, congestive heart failure, ST-segment deviation, diabetes, and major bleeding were significantly associated with higher risk of 1-year mortality. In this first large Jordanian registry of Middle Eastern patients undergoing PCI, patients treated were relatively young age population with low in-hospital and 1-year adverse cardiovascular events. Certain clinical features were associated with worse outcomes and may warrant aggressive therapeutic strategies.

Reactor-produced therapeutic radioisotopes

International Nuclear Information System (INIS)

Knapp, F.F. Jr.

2002-01-01

The significant worldwide increase in therapeutic radioisotope applications in nuclear medicine, oncology and interventional cardiology requires the dependable production of sufficient levels of radioisotopes for these applications (Reba, 2000; J. Nucl. Med., 1998; Nuclear News, 1999; Adelstein and Manning, 1994). The issues associated with both accelerator- and reactor-production of therapeutic radioisotopes is important. Clinical applications of therapeutic radioisotopes include the use of both sealed sources and unsealed radiopharmaceutical sources. Targeted radiopharmaceutical agents include those for cancer therapy and palliation of bone pain from metastatic disease, ablation of bone marrow prior to stem cell transplantation, treatment modalities for mono and oligo- and polyarthritis, for cancer therapy (including brachytherapy) and for the inhibition of the hyperplastic response following coronary angioplasty and other interventional procedures (For example, see Volkert and Hoffman, 1999). Sealed sources involve the use of radiolabeled devices for cancer therapy (brachytherapy) and also for the inhibition of the hyperplasia which is often encountered after angioplasty, especially with the exponential increase in the use of coronary stents and stents for the peripheral vasculature and other anatomical applications. Since neutron-rich radioisotopes often decay by beta decay or decay to beta-emitting daughter radioisotopes which serve as the basis for radionuclide generator systems, reactors are expected to play an increasingly important role for the production of a large variety of therapeutic radioisotopes required for these and other developing therapeutic applications. Because of the importance of the availability of reactor-produced radioisotopes for these applications, an understanding of the contribution of neutron spectra for radioisotope production and determination of those cross sections which have not yet been established is important.

Background Prior studies have described a pseudocalculus appearance in the distal common bile duct as a normal variant at cholangiography. The objective of this study is to describe the occurrence of pseudotumor in the distal common bile duct at endoscopic retrograde cholangiopancreatography (ERCP). Methods Nine patients who underwent ERCP between May 2004 and July 2008 were identified as having a transient eccentric mural-based filling defect in the distal common bile duct. A single reader systematically reviewed all studies and recorded the imaging findings. Results The mean diameter of the filling defect was 9 mm (range, 5 to 11). Eight patients had resolution of the filling defect during the same ERCP or on a subsequent ERCP, and in 2 of these patients the inferior border of the filling defect was not well visualized. The other patient underwent surgical resection of a presumed tumor with no evidence of malignancy on surgical pathology. Conclusion An eccentric mural-based filling defect in the distal common bile duct can be artifactual in nature and may reflect transient contraction of the sphincter of Oddi. Recognition of this pseudotumor may help avoid unnecessary surgery. PMID:21724120

Diclofenac Does Not Reduce the Risk of Post-endoscopic Retrograde Cholangiopancreatography Pancreatitis in Low-Risk Units.

Nonsteroidal anti-inflammatory drugs have an inhibitory role in pathogenesis of pancreatitis. Guidelines from the European Society of Gastrointestinal Endoscopy recommend routine rectal administration of 100 mg of diclofenac or indomethacin immediately before or after ERCP for all patients without contraindications. Our aim was to evaluate the effect of diclofenac in preventing post-ERCP pancreatitis (PEP) in a high-volume, low-PEP-risk ERCP unit. The rate and severity of PEP were compared in groups of 1000 historical controls prior to the routine use of diclofenac and in 1000 patients receiving 100 mg diclofenac before ERCP. PEP occurred in 56 (2.8%) of the 2000 patients, and the rate of the pancreatitis was 2.8% in control group and 2.8% in diclofenac group (p = 1.000). The PEP rate among the native papilla patients was 3.9% in control group and 3.6% in diclofenac group (p = 0.803). In subgroup analysis of patients with a high risk of PEP, diclofenac neither prevented PEP nor made its course milder. In an unselected patient population in a center with a low incidence of PEP, diclofenac seems to have no beneficial effect.

To assess the accuracy of ultrasonography (US), computed tomography (CT), and endoscopic retrograde cholangiopancreatography (ERCP) in distinguishing between benign and malignant causes of jaundice and cholestasis without jaundice, a consecutive series of patients with jaundice or cholestasis without jaundice were studied. The most common benign disease was choledocholithiasis and the most common malignant disease was carcinoma of pancreas. The benign nature of the extrahepatic obstruction was correctly defined by US, CT, and ERCP in 53%, 53%, and 90% of patients, respectively, and the corresponding figure for choledocholithiasis were 22%, 25%, and 79%. Intrahepatic benign diseases were diagnosed by US and CT in a third of cases. Malignant extrahepatic obstruction was correctly diagnosed in 57%, 80%, and 83%, respectively and the corresponding figures for pancreatic cancer were 60%, 97% and 89%. Intrahepatic malignant lesions were diagnosed by US, CT, and ERCP in 100%, 77%, and 60% of patients, respectively. When the obstruction was benign and extrahepatic ERCP was the most accurate, but when it was malignant CT was comparable. Intrahepatic disease was best diagnosed by US and CT. The results emphasise that the three methods of imaging are complementary

Therapeutic doll play in the treatment of a severely impaired psychiatric inpatient: dramatic clinical improvements with a nontraditional nursing intervention.

Interest has grown in the use of doll therapy, particularly in geropsychiatric and dementia care settings. In a long-term state psychiatric hospital, a dollhouse-play activity was implemented in an effort to engage an acutely disturbed, middle-aged woman undergoing medication trials and whose symptoms had been refractory to conventional treatments. A schedule of nondirective dollhouse-play activities was implemented over an 8-week period. Measures of behavioral change were tracked. Dramatic clinical improvements were seen, including significant reductions in verbal and physical aggression, use of as-needed medications, and need for close one-to-one monitoring. Improvements were seen prior to achievement of therapeutic drug levels. The patient was successfully discharged from the hospital. Doll play has recently been associated with clinical benefits in the care of patients with dementia and has long been deployed in childhood mental health treatment. The current findings suggest doll play may have applications as a time-limited intervention in the treatment of major psychiatric disorders in adults and warrants consideration when achieving therapeutic alliance has proven particularly challenging.

For cooled newborn infants, humidifier settings for normothermic condition provide excessive gas humidity because absolute humidity at saturation is temperature-dependent. To assess humidification of respiratory gases in patients who underwent moderate therapeutic hypothermia at a paediatric/adult intensive care unit, 6 patients were studied over 9 times. Three humidifier settings, 37-default (chamber-outlet, 37°C; Y-piece, 40°C), 33.5-theoretical (chamber-outlet, 33.5°C; Y-piece, 36.5°C), and 33.5-adjusted (optimised setting to achieve saturated vapour at 33.5°C using feedback from a thermohygrometer), were tested. Y-piece gas temperature/humidity and the incidence of high (>40.6 mg/L) and low (humidification were highlighted in patients cooled at a paediatric/adult intensive care unit. Y-piece gas conditions can be controlled to the theoretically optimal level by adjusting the setting guided by Y-piece gas temperature/humidity.

We report a third case in literature of pneumoperitoneum after ERCP due to rupture of intrahepatic bile ducts and Glisson’s capsule in a peripheral hepatic lesion. Case Report: A 50-year-old male with a history of metastatic pancreatic neuroendocrine tumor and who had a partially covered metallic stent placed in the biliary tree 1 year ago presented to the oncology clinic with fatigue, abdominal pain, and hypotension. He was planned for ERCP for possible cholangitis secondary to obstructed previously placed biliary stent. However, the duodenoscope could not be advanced to the level of the major papilla because of narrowed pylorus and severely strictured duodenal sweep. Forward-view gastroscope was then passed with careful manipulation to the severely narrowed second part of the duodenum where the previously placed metallic stent was visualized. Balloon sweeping of stenting was done. Cholangiography did not show any leak. Following the procedure, the patient underwent CT scan of the abdomen that showed pneumoperitoneum which was communicating with pneumobilia through a loculated air collection in necrotic hepatic metastasis perforating Glisson’s capsule. The patient was managed conservatively. Conclusion: In our case, pneumoperitoneum resulted from rupture of intrahepatic bile ducts and Glisson’s capsule in hepatic metastasis. This case emphasizes the need for close clinical and radiological observation of patients with hepatic masses (primary or metastatic subjected to ERCP.

Endoscopic retrograde cholangiopancreatography (ERCP) with sphincterotomy is the first step treatment modality of choledocholithiasis. In spite of an extended sphincterotomy, 10-15% of complex choledochal stones (larger than 15 mm and/or more than 3 stones) cannot be removed and recurrent ERCP procedures may be needed. To evaluate the role and efficiency of multiple biliary stent application in the treatment of large and multiple choledochal stones. Patients with complex choledochal stones and patients with inadequate choledochal clearance during ERCP were included in the study. The study group was divided into 2 groups as the placement of single (n = 27 patients) or multiple stents (n = 58 patients). After a mean time interval of 21 days (10-28), the ERCP procedure was tried for the second time and a stent was placed in case of recurrence. Successful biliary drainage was provided in both groups. The decrease in the longitudinal or transverse size of the stones after stent placement was found to be statistically significant in both groups (p = 0.001). Cholestatic enzymes (alkaline phosphatase (ALP), γ-glutamyltransferase (GGT)) and bilirubin levels decreased significantly in both groups following stenting (p = 0.001). Additionally, multiple stents functioned as a bridge starting from the first ERCP to full clearance in patients with large and multiple stones which could not be removed at once and saved them from the possible morbidities of an invasive operation. Endoscopic multiple biliary stent placement should be preferred in the treatment of patients with complex choledochal stones and high rates of co-morbidity, as a safe alternative to surgery.

This study aims to analyze the variables on which depends therapeutic discharge, in patients with a severe dual diagnosis admitted to a professional therapeutic community where their pathology is treated. 325 patients admitted between June 2000 and June 2009 to the therapeutic community. This is a retrospective, cross-sectional study with no control group, based on the detailed analysis of the information collected in a model of semi-structured clinical interview designed in the therapeutic community. The 29.5% of the individuals included in the sample were therapeutically discharged. Of all the variables introduced in this analysis the most significant ones were gender, age at the beginning of treatment, education level, opiate dependence, polidrug abuse, and the presence of psychotic disorders and borderline personality disorder. In our study, gender determines the type of discharge, being therapeutic discharge more frequent among women. A higher educational also increases a better prognosis with a higher rate of therapeutic discharge among individuals with higher education level. A later age at the beginning of the treatment reduces the likelihood of therapeutic discharge. Likewise, polidrug abuse, diagnosis of psychotic disorders and borderline personality disorder are associated to a lower rate of therapeutic discharge. Recognizing these characteristics will allow the early identification of those patients more at risk of dropping treatment hastily, while trying to prevent it by increasing the therapeutic intensity.

The Thompson encephalopathy score is a clinical score to assess newborns suffering from perinatal asphyxia. Previous studies revealed a high sensitivity and specificity of the Thompson encephalopathy score for adverse outcomes (death or severe disability). Because the Thompson encephalopathy score was developed before the use of therapeutic hypothermia, its value was reassessed. The purpose of this study was to assess the association of the Thompson encephalopathy score with adverse short-term outcomes, defined as death before discharge, development of severe epilepsy, or the presence of multiple organ failure in asphyxiated newborns undergoing therapeutic hypothermia. The study period ranged from November 2010 to October 2014. A total of 12 tertiary neonatal intensive care units participated. Demographic and clinical data were collected from the "PharmaCool" multicenter study, an observational cohort study analyzing pharmacokinetics of medication during therapeutic hypothermia. With multiple logistic regression analyses the association of the Thompson encephalopathy scores with outcomes was studied. Data of 142 newborns were analyzed (male: 86; female: 56). Median Thompson score was 9 (interquartile range: 8 to 12). Median gestational age was 40 weeks (interquartile range 38 to 41), mean birth weight was 3362 grams (standard deviation: 605). All newborns manifested perinatal asphyxia and underwent therapeutic hypothermia. Death before discharge occurred in 23.9% and severe epilepsy in 21.1% of the cases. In total, 59.2% of the patients had multiple organ failure. The Thompson encephalopathy score was not associated with multiple organ failure, but a Thompson encephalopathy score ≥12 was associated with death before discharge (odds ratio: 3.9; confidence interval: 1.3 to 11.2) and with development of severe epilepsy (odds ratio: 8.4; confidence interval: 2.5 to 27.8). The Thompson encephalopathy score is a useful clinical tool, even in cooled asphyxiated

Modeling of Filtration Processes—Microfiltration and Depth Filtration for Harvest of a Therapeutic Protein Expressed in Pichia pastoris at Constant Pressure

Full Text Available Filtration steps are ubiquitous in biotech processes due to the simplicity of operation, ease of scalability and the myriad of operations that they can be used for. Microfiltration, depth filtration, ultrafiltration and diafiltration are some of the most commonly used biotech unit operations. For clean feed streams, when fouling is minimal, scaling of these unit operations is performed linearly based on the filter area per unit volume of feed stream. However, for cases when considerable fouling occurs, such as the case of harvesting a therapeutic product expressed in Pichia pastoris, linear scaling may not be possible and current industrial practices involve use of 20–30% excess filter area over and above the calculated filter area to account for the uncertainty in scaling. In view of the fact that filters used for harvest are likely to have a very limited lifetime, this oversizing of the filters can add considerable cost of goods for the manufacturer. Modeling offers a way out of this conundrum. In this paper, we examine feasibility of using the various proposed models for filtration of a therapeutic product expressed in Pichia pastoris at constant pressure. It is observed that none of the individual models yield a satisfactory fit of the data, thus indicating that more than one fouling mechanism is at work. Filters with smaller pores were found to undergo fouling via complete pore blocking followed by cake filtration. On the other hand, filters with larger pores were found to undergo fouling via intermediate pore blocking followed by cake filtration. The proposed approach can be used for more accurate sizing of microfilters and depth filters.

Triple antithrombotic therapy increases the risk of bleeding events in patients undergoing percutaneous coronary intervention. However, it remains unclear whether good control of percent time in therapeutic range is associated with reduced occurrence of bleeding complications in patients undergoing triple antithrombotic therapy. This study included 2648 patients (70 ± 11 years; 2037 men) who underwent percutaneous coronary intervention with stent in the Ibaraki Cardiovascular Assessment Study registry and received dual antiplatelet therapy with or without warfarin. Clinical end points were defined as the occurrence of major bleeding complications (MBC), major adverse cardiac and cerebrovascular event, and all-cause death. Among these 2648 patients, 182 (7%) patients received warfarin. After a median follow-up period of 25 months (interquartile range, 15-35 months), MBC had occurred in 48 (2%) patients, major adverse cardiac and cerebrovascular event in 484 (18%) patients, and all-cause death in 206 (8%) patients. Multivariable Cox regression analysis revealed that triple antithrombotic therapy was the independent predictor for the occurrence of MBC (hazard ratio, 7.25; 95% confidence interval, 3.05-17.21; Prange value did not differ between the patients with and without MBC occurrence (83% [interquartile range, 50%-90%] versus 75% [interquartile range, 58%-87%]; P=0.7). However, the mean international normalized ratio of prothrombin time at the time of MBC occurrence was 3.3 ± 2.1. Triple antithrombotic therapy did not have a predictive value for the occurrence of all-cause death (P=0.1) and stroke (P=0.2). Triple antithrombotic therapy predisposes patients to an increased risk of MBC regardless of the time in therapeutic range.

Endoscopic ultrasound (EUS)-assisted biliary access is utilized when conventional endoscopic retrograde cholangiopancreatography (ERCP) fails. We report a 10-year experience utilizing a transduodenal EUS rendezvous via a transpapillary route without dilation of the transduodenal tract, followed by immediate ERCP access. Patients included all EUS-guided rendezvous procedures for biliary access that were performed following ERCP failure. EUS-assisted bile duct puncture was performed via a transduodenal approach and a guide wire was advanced through the papilla without any dilation or bougienage of the tract; ERCP was performed immediately afterwards. EUS-assisted biliary rendezvous was attempted in 15 patients (mean age 66 +/- 18.2 years; malignant = 10, benign = 5). Mean diameter of measured bile ducts was 14.3 +/- 5.17 mm (range 4-23 mm). The reasons for initial ERCP failure were tumor infiltration or edema (n = 9), intradiverticular papilla (n = 2), pre-existing duodenal stent (n = 1), and anatomic anomalies (n = 3). Successful EUS-guided bile duct puncture and wire passage were achieved in all 15 patients (100 %), with drainage being successful in 12 / 15 (80 %). Failures occurred in three patients due to inability to traverse the biliary stricture (n = 2) or dissection of a choledochocele with the guide wire (n = 1); all were subsequently drained via percutaneous methods. Stents placed were metallic in eight patients and plastic in four. Complications consisted of moderate pancreatitis after a difficult ERCP attempt in one patient, and bacteremia after percutaneous biliary drainage in another. There were no instances of perforation, extraluminal air or fluid collections. EUS-assisted biliary drainage utilizing a transduodenal rendezvous approach demonstated a high success rate without any complications directly attributable to the EUS access. Advantages over percutaneous biliary and other methods of EUS biliary access include performance under the same

Full Text Available The incidence of papillary thyroid carcinoma (PTC has risen steadily over the past few decades as well as the recurrence rates. It has been proposed that targeted ablative physical therapy could be a therapeutic modality in thyroid cancer. Targeted bio-affinity functionalized multi-walled carbon nanotubes (BioNanofluid act locally, to efficiently convert external light energy to heat thereby specifically killing cancer cells. This may represent a promising new cancer therapeutic modality, advancing beyond conventional laser ablation and other nanoparticle approaches.Thyroid Stimulating Hormone Receptor (TSHR was selected as a target for PTC cells, due to its wide expression. Either TSHR antibodies or Thyrogen or purified TSH (Thyrotropin were chemically conjugated to our functionalized Bionanofluid. A diode laser system (532 nm was used to illuminate a PTC cell line for set exposure times. Cell death was assessed using Trypan Blue staining.TSHR-targeted BioNanofluids were capable of selectively ablating BCPAP, a TSHR-positive PTC cell line, while not TSHR-null NSC-34 cells. We determined that a 2:1 BCPAP cell:α-TSHR-BioNanofluid conjugate ratio and a 30 second laser exposure killed approximately 60% of the BCPAP cells, while 65% and >70% of cells were ablated using Thyrotropin- and Thyrogen-BioNanofluid conjugates, respectively. Furthermore, minimal non-targeted killing was observed using selective controls.A BioNanofluid platform offering a potential therapeutic path for papillary thyroid cancer has been investigated, with our in vitro results suggesting the development of a potent and rapid method of selective cancer cell killing. Therefore, BioNanofluid treatment emphasizes the need for new technology to treat patients with local recurrence and metastatic disease who are currently undergoing either re-operative neck explorations, repeated administration of radioactive iodine and as a last resort external beam radiation or chemotherapy, with

Transforming growth factor {beta}1 (TGF{beta}) is a tumor suppressor during the initial stage of tumorigenesis, but it can switch to a tumor promoter during neoplastic progression. Ionizing radiation (IR), both a carcinogen and a therapeutic agent, induces TGF{beta}, activation in vivo. We now show that IR sensitizes human mammary epithelial cells (HMEC) to undergo TGF{beta}-mediated epithelial to mesenchymal transition (EMT). Non-malignant HMEC (MCF10A, HMT3522 S1 and 184v) were irradiated with 2 Gy shortly after attachment in monolayer culture, or treated with a low concentration of TGF{beta} (0.4 ng/ml), or double-treated. All double-treated (IR+TGF{beta}) HMEC underwent a morphological shift from cuboidal to spindle-shaped. This phenotype was accompanied by decreased expression of epithelial markers E-cadherin, {beta}-catenin and ZO-1, remodeling of the actin cytoskeleton, and increased expression of mesenchymal markers N-cadherin, fibronectin and vimentin. Furthermore, double-treatment increased cell motility, promoted invasion and disrupted acinar morphogenesis of cells subsequently plated in Matrigel{trademark}. Neither radiation nor TGF{beta} alone elicited EMT, even though IR increased chronic TGF{beta} signaling and activity. Gene expression profiling revealed that double treated cells exhibit a specific 10-gene signature associated with Erk/MAPK signaling. We hypothesized that IR-induced MAPK activation primes non-malignant HMEC to undergo TGF{beta}-mediated EMT. Consistent with this, Erk phosphorylation were transiently induced by irradiation, persisted in irradiated cells treated with TGF{beta}, and treatment with U0126, a Mek inhibitor, blocked the EMT phenotype. Together, these data demonstrate that the interactions between radiation-induced signaling pathways elicit heritable phenotypes that could contribute to neoplastic progression.

Natriuretic peptides are a family of peptides with similar structures, but are genetically distinct with diverse actions in cardiovascular, renal and fluid homeostasis. The family consists of an atrial natriuretic peptide (ANP) and a brain natriuretic peptide (BNP) of myocardial cell origin, a C-type natriuretic peptide (CNP) of endothelial origin, and a urodilatin (Uro) which is processed from a prohormone ANP in the kidney. Nesiritide, a human recombinant BNP, was approved by the Federal Drug Administration (FDA) for the management of acute heart failure (AHF) in 2001. Human recombinant ANP (Carperitide) was approved for the same clinical indication in Japan in 1995, and human recombinant Urodilatin (Ularitide) is currently undergoing phase III clinical trial (TRUE AHF). This review will provide an update on important issues regarding the role of BNP in fluid hemostasis as a biomarker and therapeutics in AHF.

2017-04-01

Full Text Available Laparoscopic cholecystectomy has become the standard procedure for the surgical management of symptomatic cholelithiasis. Laparoscopic cholecystectomy is generally considered a safe procedure although a few complications such as major bleeding, wound infection, bile leakage, biliary and bowel injury are well known. We are reporting a case of a thirty-seven year old male who presented with abdominal pain, three weeks after laparoscopic cholecystectomy. Abdominal ultrasound revealed a filling defect in common bile duct with deranged liver function tests. With an impression of choledocholithiasis, his endoscopic retrograde cholangiopancreatography (ERCP was done which revealed a surgical clip impacted in the ampulla. The surgical clip was retrieved successfully by ERCP. Intraductal clip migration is a rarely encountered complication after laparoscopic cholecystectomy. Appropriate management requires timely identification and retrieval during ERCP.

Objectives This study aimed to review general anaesthesia protocols for patients undergoing electroconvulsive therapy (ECT) at a tertiary care hospital in Oman, particularly with regards to clinical profile, potential drug interactions and patient outcomes. Methods This retrospective study took place at the Sultan Qaboos University Hospital (SQUH), Muscat, Oman. The electronic medical records of patients undergoing ECT at SQUH between January 2010 and December 2014 were reviewed for demographic characteristics and therapy details. Results A total of 504 modified ECT sessions were performed on 57 patients during the study period. All of the patients underwent a uniform general anaesthetic regimen consisting of propofol and succinylcholine; however, they received different doses between sessions, as determined by the treating anaesthesiologist. Variations in drug doses between sessions in the same patient could not be attributed to any particular factor. Self-limiting tachycardia and hypertension were periprocedural complications noted among all patients. One patient developed aspiration pneumonitis (1.8%). Conclusion All patients undergoing ECT received a general anaesthetic regimen including propofol and succinylcholine. However, the interplay of anaesthetic drugs with ECT efficacy could not be established due to a lack of comprehensive data, particularly with respect to seizure duration. In addition, the impact of concurrent antipsychotic therapy on anaesthetic dose and subsequent complications could not be determined. PMID:28417028

Limited research examines the risk of therapeutic opioid addiction (TOA) in patients with chronic noncancer pain. This study examined TOA among 199 patients undergoing long-term opioid therapy at the time of admission to a pain rehabilitation program. It was hypothesized that nonopioid substance use disorders and opioid dosage would predict TOA. Daily mean opioid dose was 132.85 mg ± 175.39. Patients with nonopioid substance use disorders had 28 times the odds (odds ratio [OR] = 28.58; 95% confidence interval [CI] = 10.86, 75.27) of having TOA. Each 50-mg increase in opioid dose nearly doubled the odds of TOA (OR = 1.73; 95% CI = 1.29, 2.32). A 100-mg increase was associated with a 3-fold increase in odds (OR = 3.00; 95% CI = 1.67, 5.41). Receiver operating characteristic analysis revealed that opioid dose was a moderately accurate predictor (area under the curve = .75; 95% CI = .68, .82) of TOA. The sensitivity (.70) and specificity (.68) of opioid dose in predicting TOA was maximized at 76.10 mg; in addition, 46.00 mg yielded 80% sensitivity in identifying TOA. These results underscore the importance of obtaining a substance use history prior to prescribing and suggest a low screening threshold for TOA in patients who use opioids in the absence of improvement in pain or functional impairment. This article examines TOA in patients with chronic noncancer pain undergoing long-term opioid therapy. Results suggest that patients should be screened for nonopioid substance use disorders prior to prescribing. In the absence of improvement in pain or function, there is a low threshold (∼50 mg daily opioid dose) for addiction screening. Copyright © 2015 American Pain Society. Published by Elsevier Inc.

Prevention of COPD requires appropriate patient education, especially of adolescents, as well as the establishment of an effective national health policy. The new GOLD guidelines represent the current standard of knowledge on the management of chronic, progressive, obstructive pulmonary diseases. It points out that COPD is avoidable and treatable,and hence, there is no reason for therapeutic nihilism. Chronic bronchitis preceding a progressive respiratory obstruction cannot be improved with the presently available respiratory therapeutics. For this reason, therapeutic measures concentrate on the avoidance of exacerbations, which are primarily responsible for the severity of the course of COPD.

Laparoscopic common bile duct exploration (CBDE) is becoming more popular in the management of choledocholithiasis due to improved laparoscopic expertise and advancement in endoscopic technology and equipment. This study aimed to evaluate the safety and short-term outcome of laparoscopic CBDE in a single institution over a 3-year period. A retrospective review of the records of all patients who underwent laparoscopic CBDE in Tan Tock Seng Hospital between January 2006 and September 2008 was conducted. Fifty consecutive patients, with a median age of 60 years (range, 27 to 85) underwent laparoscopic CBDE for choledocholithiasis during the study period. About half of our patients presented as an emergency with acute cholangitis (32.0%) accounting for the majority. A total of 22 (44.0%) patients underwent laparoscopic CBDE as their primary procedure while the remaining 28 (56.0%) were subjected to preoperative ERCP initially. Of the latter group, documented stone clearance was only documented in 5 (17.9%) patients. Laparoscopic CBDE via the transcystic route was performed in 27 (54.0%) patients while another 18 patients (36.0%) had laparoscopic choledochotomy and 1 patient (2.0%) had laparoscopic choledocho-duodenostomy. There were 4 (8.0%) conversions in our series. The median operative time for laparoscopic CBDE via the transcystic route and the laparoscopic choledochotomy were 170 (75-465) and 250 (160-415) minutes, respectively. For the 18 patients who underwent a laparoscopic choledochotomy, T-tube was inserted in 8 (44.4%) patients while an internal biliary stent was placed in 4 (22.2%) with the remaining 6 patients (33.3%) undergoing primary closure of the choledochotomy. The median length of hospital stay was 2 days (range, 1 to 15) with no associated mortality. The main complications (n = 4, 8.0%) included retained CBD stones and biliary leakage. These were treated successfully with postoperative endoscopic retrograde cholangiopancreatography (ERCP) with

New concepts in therapeutic photomedicine: photochemistry, optical targeting and the therapeutic window

Advances in optics technology, synthetic photochemistry, and the science of photobiology make it possible to think beyond phototherapy and photochemotherapy which is dependent on direct photochemical alteration of metabolites or direct phototoxic insult to cells. This report discusses another gender of photomedicine therapy which includes in vivo photoactivation of medicines, photon-dependent drug delivery, and manipulation of host and exposure source to maximize therapeutic index. These therapeutic manipulations are made possible because the skin is highly overperfused and because non-ionizing electromagnetic radiation that enters skin and blood has adequate photon energy to cause electronic excitation. Radiation of 320-800 nm is not very directly phototoxic, is absorbed by a variety of relatively nontoxic photolabile molecules and has an internal dosimetric depth profile. This radiation can therefore be used to activate, deactivate, bind, release or biotransform medications in vivo in skin or other organs. The photochemist, synthetic chemist and photobiologist can collaborate to significantly increase therapeutic possibilities

Oncolytic Viruses: Therapeutics With an Identity Crisis

Directory of Open Access Journals (Sweden)

Caroline J. Breitbach

2016-07-01

Full Text Available Oncolytic viruses (OV are replicating viral therapeutics for the treatment of cancer and have been in laboratory development for about twenty years. Recently, the FDA approved Imlygic, a herpes virus based therapeutic for the treatment of melanoma and thus OVs have entered a new era where they are a weapon in the armament of the oncologist. OVs are unique therapeutics with multiple mechanisms of therapeutic activity. The exact path for their development and eventual uptake by pharmaceutical companies is somewhat clouded by an uncertain identity. Are they vaccines, tumour lysing therapeutics, inducers of innate immunity, gene therapy vectors, anti-vascular agents or all of the above? Should they be developed as stand-alone loco-regional therapeutics, systemically delivered tumour hunters or immune modulators best tested as combination therapeutics? We summarize data here supporting the idea, depending upon the virus, that OVs can be any or all of these things. Pursuing a “one-size fits all” approach is counter-productive to their clinical development and instead as a field we should build on the strengths of individual virus platforms.

Mycotic aneurysms : radiological diagnosis and therapeutic alternatives

To review mycotic aneurysms, their radiological diagnosis and therapeutic alternatives. Five men and a woman between 69 and 84 years old were diagnosed during the last 4 years with mycotic aneurysms. Three were in the aorta, one in the thoracic and two in the abdominal region; one was affecting the left primitive iliac artery, another the left popliteal artery and, in the last case, the medial cerebral artery. Hemo cultures were done on all patients. The surgical specimen was cultivated in 4. CAT was done on 5 patients, angiography on another five and Doppler ultrasound scan on two. Five patients showed positive hemo cultures and in two the surgical specimen culture was positive. The findings of the CAT were decisive in being able to suspect that the lesions were mycotic in nature. Three patients had to undergo emergency, expiring either in surgery or in postoperative care. One case was treated by means of aortic endo prosthesis, and one year later the patient remains asymptomatic. The cerebral aneurysm was embolized with metal coils and the patient remains asymptomatic three years later. The popliteal aneurysm underwent surgical intervention using an established protocol with good results. CAT is decisive in the diagnosis of mycotic aneurysms. Once detected, they must be treated without delay as their natural evolution is one of rapid expansion and rupture. Angiographies help in planning the treatment. Radiological intervention plays an important role in the treatment. (Author) 13 refs

Coagulation management in patients undergoing neurosurgical procedures.

2017-10-01

Management of coagulation in neurosurgical procedures is challenging. In this contest, it is imperative to avoid further intracranial bleeding. Perioperative bleeding can be associated with a number of factors, including anticoagulant drugs and coagulation status but is also linked to the characteristic and the site of the intracranial disorder. The aim of this review will be to focus primarily on the new evidence regarding the management of coagulation in patients undergoing craniotomy for neurosurgical procedures. Antihemostatic and anticoagulant drugs have shown to be associated with perioperative bleeding. On the other hand, an increased risk of venous thromboembolism and hypercoagulative state after elective and emergency neurosurgery, in particular after brain tumor surgery, has been described in several patients. To balance the risk between thrombosis and bleeding, it is important to be familiar with the perioperative changes in coagulation and with the recent management guidelines for anticoagulated patients undergoing neurosurgical procedures, in particular for those taking new direct anticoagulants. We have considered the current clinical trials and literature regarding both safety and efficacy of deep venous thrombosis prophylaxis in the neurosurgical population. These were mainly trials concerning both elective surgical and intensive care patients with a poor grade intracranial bleed or multiple traumas with an associated severe traumatic brain injury (TBI). Coagulation management remains a major issue in patients undergoing neurosurgical procedures. However, in this field of research, literature quality is poor and further studies are necessary to identify the best strategies to minimize risks in this group of patients.

To characterize the profile and speech characteristics of patients undergoing primary palatoplasty in a Brazilian university hospital, considering the time of intervention (early, before two years of age; late, after two years of age). Participants were 97 patients of both genders with cleft palate and/or cleft and lip palate, assigned to the Speech-language Pathology Department, who had been submitted to primary palatoplasty and presented no prior history of speech-language therapy. Patients were divided into two groups: early intervention group (EIG) - 43 patients undergoing primary palatoplasty before 2 years of age and late intervention group (LIG) - 54 patients undergoing primary palatoplasty after 2 years of age. All patients underwent speech-language pathology assessment. The following parameters were assessed: resonance classification, presence of nasal turbulence, presence of weak intraoral air pressure, presence of audible nasal air emission, speech understandability, and compensatory articulation disorder (CAD). At statistical significance level of 5% (p≤0.05), no significant difference was observed between the groups in the following parameters: resonance classification (p=0.067); level of hypernasality (p=0.113), presence of nasal turbulence (p=0.179); presence of weak intraoral air pressure (p=0.152); presence of nasal air emission (p=0.369), and speech understandability (p=0.113). The groups differed with respect to presence of compensatory articulation disorders (p=0.020), with the LIG presenting higher occurrence of altered phonemes. It was possible to assess the general profile and speech characteristics of the study participants. Patients submitted to early primary palatoplasty present better speech profile.

Full Text Available Burn injuries are a leading cause of morbidity including prolonged hospitalization, disfigurement, and disability. Currently there is no Food and Drug Administration-approved burn therapeutics. A clinical distinction of burn injuries from other acute wounds is the event of the so-called secondary burn wound progression within the first week of the injury, in which a burn expands horizontally and vertically from its initial boundary to a larger area. Therefore, an effective therapeutics for burns should show dual abilities to prevent the burn wound progression and thereafter promote burn wound healing. Herein we report that topically applied F-5 fragment of heat shock protein-90α is a dual functional agent to promote burn wound healing in pigs. First, F-5 prevents burn wound progression by protecting the surrounding cells from undergoing heat-induced caspase 3 activation and apoptosis with increased Akt activation. Accordingly, F-5–treated burn and excision wounds show a marked decline in inflammation. Thereafter, F-5 accelerates burn wound healing by stimulating the keratinocyte migration-led reepithelialization, leading to wound closure. This study addresses a topical agent that is capable of preventing burn wound progression and accelerating burn wound healing.

BACKGROUND Anatomical variations in the biliary system have been proven to be of clinical importance. Awareness of the pattern of these variations in a specific population may help to prevent and manage biliary injuries during surgical and endoscopic procedures. Knowledge of the biliary anatomy will be also of great help in planning the drainage of adequate percentage of liver parenchyma in endoscopic or radiological procedures. METHODS All consecutive patients undergoing endoscopic retrograde cholangiopancreatography (ERCP) from April 2013 to April 2015 at Nemazee Hospital, a referral center in the south of Iran, were included in this cross-sectional study. The patients with previous hepatic or biliary surgery, liver injury or destructive biliary disease were excluded from the study. All ERCPs were reviewed by two expert gastroenterologists in this field. The disagreed images by the two gastroenterologists were excluded. Huang classification was used for categorizing the different structural variants of the biliary tree, and the frequency of each variant was recorded. RESULTS Totally, 362 patients (181 men and 181 women) were included in the study. 163 patients (45%) had type A1 Huang classification (right dominant), which was the most prevalent type among our patients. 55% of them had non-right dominant anatomy. The result of the Chi-square test revealed that there was no statistically significant difference between the men and women regarding the anatomical variations (p = 0.413). CONCLUSION The anatomical variation in the biliary system among Iranian patients is comparable to other regions of the world. Significant proportions of our patients are non-right dominant and may need bilateral biliary drainage.

Bile leakage, while rare, can be a complication seen after cholecystectomy. It may also occur after hepatic or biliary surgical procedures. Etiology may be underlying pathology or surgical complication. Endoscopic retrograde cholangiopancreatography (ERCP) can play major role in diagnosis and treatment of bile leakage. Present study was a retrospective analysis of outcomes of ERCP procedure in patients with bile leakage. Patients who underwent ERCP for bile leakage after surgery between 2008 and 2012 were included in the study. Etiology, clinical and radiological characteristics, and endoscopic treatment outcomes were recorded and analyzed. Total of 31 patients (10 male, 21 female) were included in the study. ERCP was performed for bile leakage after cholecystectomy in 20 patients, after hydatid cyst operation in 10 patients, and after hepatic resection in 1 patient. Clinical signs and symptoms of bile leakage included abdominal pain, bile drainage from percutaneous drain, peritonitis, jaundice, and bilioma. Twelve (60%) patients were treated with endoscopic sphincterotomy (ES) and nasobiliary drainage (NBD) catheter, 7 patients (35%) were treated with ES and biliary stent (BS), and 1 patient (5%) was treated with ES alone. Treatment efficiency was 100% in bile leakage cases after cholecystectomy. Ten (32%) cases of hydatid cyst surgery had subsequent cystobiliary fistula. Of these patients, 7 were treated with ES and NBD, 2 were treated with ES and BS, and 1 patient (8%) with ES alone. Treatment was successful in 90% of these cases. ERCP is an effective method to diagnose and treat bile leakage. Endoscopic treatment of postoperative bile leakage should be individualized based on etiological and other factors, such as accompanying fistula.

Full text: Introduction: The risk of bile duct injury after laparoscopic cholecystectomy is higher than open cholecystectomy. Objective: To discuss the importance of minimally invasive treatment options in the management of bile duct injuries after laparoscopic cholecystectomy and to present our approach in the management. Materials and methods: Management of 25 patients with symptomatic bile duct injury after laparoscopic cholecystectomy was retrospectively evaluated. Percutaneous collection drainage, endoscopic retrograde cholangiopancreatography (ERCP), percutaneous transhepatic cholangiography (PTC) and percutaneous biliary drainage were performed for the management of the patients. Results: Mean age of the patients (15 women, 10 men) was 55. Either ultrasonography or computed tomography guided percutaneous drainage was performed in 13 patients. 9 of them completely recovered only with percutaneous drainage. In 4 of them ERCP was performed because of high drainage volume. In 9 of the patients with jaundice and high bilirubin levels ERCP was performed as the first option. And 3 patients were reoperated because of acute abdomen signs. ERCP, MRCP and PTC revealed type A in 7, type E2 in 3, type E3 in 3 and type E4 in 1 of the patients according to Strasberg classification. Conclusion: Presenting symptoms of the patients with symptomatic bile duct injury are useful in the determination of the treatment option.

We invented a drape-like shield against scattered X-rays that can safely come into contact with medical equipment or people during fluoroscopically guided procedures. The shield can be easily removed from a C-arm unit using one hand. We evaluated the use of the novel removable shield during the endoscopic retrograde cholangiopancreatography (ERCP) procedure. We measured the dose rate of scattered X-rays around endoscopists with and without this removable shield and surveyed the occupational doses to the ERCP staff. We also examined the endurance of the shield. The removable shield reduced the dose rate of scattered X-rays to one-tenth and reduced the monthly dose to an endoscopist by at least two-fifths. For 2.5 years, there was no damage to the shield and no loosening of the seam. The bonding of the hook-and-loop fasteners did not weaken, although the powerful double-sided tapes made especially for plastic did. The removable shield can reduce radiation exposure to the ERCP staff and may contribute to reducing the exposure to the eye lenses of operators. It would also be possible to expand its use to other fluoroscopically guided procedures besides ERCP because it is a light, simple, and useful device. (orig.)

Evolving Role of Endoscopic Retrograde Cholangiopancreatography in Management of Extrahepatic Hepatic Ductal Injuries due to Blunt Trauma: Diagnostic and Treatment Algorithms

Full Text Available Extrahepatic hepatic ductal injuries (EHDIs due to blunt abdominal trauma are rare. Given the rarity of these injuries and the insidious onset of symptoms, EHDI are commonly missed during the initial trauma evaluation, making their diagnosis difficult and frequently delayed. Diagnostic modalities useful in the setting of EHDI include computed tomography (CT, abdominal ultrasonography (AUS, nuclear imaging (HIDA scan, and cholangiography. Traditional options in management of EHDI include primary ductal repair with or without a T-tube, biliary-enteric anastomosis, ductal ligation, stenting, and drainage. Simple drainage and biliary decompression is often the most appropriate treatment in unstable patients. More recently, endoscopic retrograde cholangiopancreatography (ERCP allowed for diagnosis and potential treatment of these injuries via stenting and/or papillotomy. Our review of 53 cases of EHDI reported in the English-language literature has focused on the evolving role of ERCP in diagnosis and treatment of these injuries. Diagnostic and treatment algorithms incorporating ERCP have been designed to help systematize and simplify the management of EHDI. An illustrative case is reported of blunt traumatic injury involving both the extrahepatic portion of the left hepatic duct and its confluence with the right hepatic duct. This injury was successfully diagnosed and treated using ERCP.

Full Text Available Cardiac glycosides have been used for congestive heart failure and certain cardiac arrhythmias for more than 200 years. Despite the introduction of a variety of new classes of drugs for the management of heart failure, specifically angiotensin-converting enzyme (ACE inhibitors, b-adrenergic antagonists (bblockers, and the aldosterone antagonist spironolactone, digoxin continues to have an important role in long-term outpatient management. However, a narrow margin exists between therapeutic and toxic doses of digoxin, resulting in a high incidence of digoxin toxicity in clinical practice.A wide variety of placebo-controlled clinical trials have unequivocally shown that treatment with digoxin can improve symptoms, quality of life, and exercise tolerance in patients with mild, moderate, or severe heart failure. The clinical relevance of digoxin therapeutic monitoring is also proved but the SDC (Serum Digoxin Conentrations required for optimal clinical efficacy and acceptable toxicity remains controversial. In the last years, international guidelines recommend 1.2 ng/mL as acceptable high level.In this bibliographic synthesis, we aim to collect pertinent informations from MedLine database about exposure-effect relationship in order to assess the evidence level scientific of new digoxin therapeutic monitoring.

A pilot initiative to assess the use of remote video auditing in monitoring compliance with manual-cleaning protocols for endoscopic retrograde cholangiopancreatography (ERCP) endoscopes was performed. Compliance with manual-cleaning steps following the initiation of feedback was measured. A video feed of the ERCP reprocessing room was provided to remote auditors who scored items of an ERCP endoscope manual-cleaning checklist. Compliance feedback was provided in the form of reports and reeducation. Outcomes were reported as checklist compliance. The use of remote video auditing to document manual processing is a feasible approach and feedback and reeducation increased manual-cleaning compliance from 53.1% (95% confidence interval, 34.7-71.6) to 98.9% (95.0% confidence interval, 98.1-99.6).

Pulsed photothermal radiometry (PPTR) allows noninvasive determination of temperature depth profiles induced by pulsed laser irradiation of strongly scattering biological tissues and organs, including human skin. In present study, we evaluate the potential of this technique for investigational characterization and possibly quantitative evaluation of laser tattoo removal. The study involved 5 healthy volunteers (3 males, 2 females), age 20-30 years, undergoing tattoo removal treatment using a Q-switched Nd:YAG laser. There were four measurement and treatment sessions in total, separated by 2-3 months. Prior to each treatment, PPTR measurements were performed on several tattoo sites and one nearby healthy site in each patient, using a 5 ms Nd:YAG laser at low radiant exposure values and a dedicated radiometric setup. The laser-induced temperature profiles were then reconstructed by applying a custom numerical code. In addition, each tatoo site was documented with a digital camera and measured with a custom colorimetric system (in tristimulus color space), providing an objective evaluation of the therapeutic efficacy to be correlated with our PPTR results. The results show that the laser-induced temperature profile in untreated tattoos is invariably located at a subsurface depth of 300 μm. In tattoo sites that responded well to laser therapy, a significant drop of the temperature peak was observed in the profiles obtained from PPTR record. In several sites that appeared less responsive, as evidenced by colorimetric data, a progressive shift of the temperature profile deeper into the dermis was observed over the course of consecutive laser treatments, indicating that the laser tattoo removal was efficient.

Background Of the 1.5 million people diagnosed with pleural effusion annually in the U.S., approximately 178,000 undergo thoracentesis. While it is known that malignant pleural effusion portends a poor prognosis, mortality of patients with nonmalignant effusions has not been well studied. Methods This prospective cohort study evaluated 308 patients undergoing thoracentesis. Chart review was performed to obtain baseline characteristics. The etiology of the effusions was determined using standardized criteria. Mortality was determined at 30-days and 1-year. Results 247 unilateral and 61 bilateral thoracenteses were performed. Malignant effusion had the highest 30-day (37%) and 1 year (77%) mortality. There was substantial patient 30-day and 1-year mortality with effusions due to multiple benign etiologies (29% and 55%), CHF (22% and 53%), and renal failure (14% and 57%). Patients with bilateral pleural effusion, relative to unilateral, were associated with higher risk of death at 30 days and 1 year (17% versus 47%; HR 2.58 CI [1.44–4.63] and 36% versus 69%; HR 2.32 CI [1.55–3.48]). Conclusions Patients undergoing thoracentesis for pleural effusion have high short and long-term mortality. Patients with malignant effusion had the highest mortality followed by multiple benign etiologies, CHF and renal failure. Bilateral pleural effusion is distinctly associated with high mortality.

Cha, Eugene K; Eastham, James A

2015-05-01

Although both surgery and radiation are potential curative options for men with clinically localized prostate cancer, a significant proportion of men with high-risk and locally advanced disease will demonstrate biochemical and potentially clinical progression of their disease. Neoadjuvant systemic therapy before radical prostatectomy (RP) is a logical strategy to improve treatment outcomes for men with clinically localized high-risk prostate cancer. Furthermore, delivery of chemotherapy and other systemic agents before RP affords an opportunity to explore the efficacy of these agents with pathologic end points. Neoadjuvant chemotherapy, primarily with docetaxel (with or without androgen deprivation therapy), has demonstrated feasibility and safety in men undergoing RP, but no study to date has established the efficacy of neoadjuvant chemotherapy or neoadjuvant chemohormonal therapies. Other novel agents, such as those targeting the vascular endothelial growth factor receptor, epidermal growth factor receptor, platelet-derived growth factor receptor, clusterin, and immunomodulatory therapeutics, are currently under investigation.

The development of efficient strategies for generating fully human monoclonal antibodies with unique functional properties that are exploitable for tailored therapeutic interventions remains a major challenge in the antibody technology field. Here, we present a methodology for recovering such antibodies from antigen-encountered human B cell repertoires. As the source for variable antibody genes, we cloned immunoglobulin G (IgG)-derived B cell repertoires from lymph nodes of 20 individuals undergoing surgery for head and neck cancer. Sequence analysis of unselected “LYmph Node Derived Antibody Libraries” (LYNDAL) revealed a naturally occurring distribution pattern of rearranged antibody sequences, representing all known variable gene families and most functional germline sequences. To demonstrate the feasibility for selecting antibodies with therapeutic potential from these repertoires, seven LYNDAL from donors with high serum titers against herpes simplex virus (HSV) were panned on recombinant glycoprotein B of HSV-1. Screening for specific binders delivered 34 single-chain variable fragments (scFvs) with unique sequences. Sequence analysis revealed extensive somatic hypermutation of enriched clones as a result of affinity maturation. Binding of scFvs to common glycoprotein B variants from HSV-1 and HSV-2 strains was highly specific, and the majority of analyzed antibody fragments bound to the target antigen with nanomolar affinity. From eight scFvs with HSV-neutralizing capacity in vitro,the most potent antibody neutralized 50% HSV-2 at 4.5 nM as a dimeric (scFv)2. We anticipate our approach to be useful for recovering fully human antibodies with therapeutic potential.

Stress modeling in colloidal dispersions undergoing non-viscometric flows

Science.gov (United States)

Dolata, Benjamin; Zia, Roseanna

2017-11-01

We present a theoretical study of the stress tensor for a colloidal dispersion undergoing non-viscometric flow. In such flows, the non-homogeneous suspension stress depends on not only the local average total stresslet-the sum of symmetric first moments of both the hydrodynamic traction and the interparticle force-but also on the average quadrupole, octupole, and higher-order moments. To compute the average moments, we formulate a six dimensional Smoluchowski equation governing the microstructural evolution of a suspension in an arbitrary fluid velocity field. Under the conditions of rheologically slow flow, where the Brownian relaxation of the particles is much faster than the spatiotemporal evolution of the flow, the Smoluchowski equation permits asymptotic solution, revealing a suspension stress that follows a second-order fluid constitutive model. We obtain a reciprocal theorem and utilize it to show that all constitutive parameters of the second-order fluid model may be obtained from two simpler linear-response problems: a suspension undergoing simple shear and a suspension undergoing isotropic expansion. The consequences of relaxing the assumption of rheologically slow flow, including the appearance of memory and microcontinuum behaviors, are discussed.

The International Commission of Radiology recommends a pregnancy screening test to all female patients of childbearing age who will undergo a radiological study. Radiation is known to be teratogenic and its effect is cumulative. The teratogenic potential starts at doses close to those used during these procedures. The prevalence of positive pregnancy tests in patients undergoing electrophysiological studies and/or catheter ablation in our midst is unknown. To evaluate the prevalence of positive pregnancy tests in female patients referred for electrophysiological study and/or radiofrequency ablation. Cross-sectional study analyzing 2,966 patients undergoing electrophysiological study and/or catheter ablation, from June 1997 to February 2013, in the Institute of Cardiology of Rio Grande do Sul. A total of 1490 procedures were performed in women, of whom 769 were of childbearing age. All patients were screened with a pregnancy test on the day before the procedure. Three patients tested positive, and were therefore unable to undergo the procedure. The prevalence observed was 3.9 cases per 1,000 women of childbearing age. Because of their safety and low cost, pregnancy screening tests are indicated for all women of childbearing age undergoing radiological studies, since the degree of ionizing radiation needed for these procedures is very close to the threshold for teratogenicity, especially in the first trimester, when the signs of pregnancy are not evident.

Full Text Available Background. Infliximab (IFX therapeutic drug monitoring (TDM allows for objective decision making in patients with inflammatory bowel disease (IBD and loss of response. Questions remain about whether IFX TDM improves outcomes. Methods. Patients with IBD who had IFX TDM due to concerns for loss of response were considered for inclusion. Serum IFX trough concentration and anti-drug antibody (ADA concentrations were measured. Patients were grouped by TDM results: group 1, low IFX/high ADA; group 2, low IFX/low ADA; group 3, therapeutic IFX. Changes in management were analyzed according to groupings; remission rates were assessed at 6 months. Results. 71 patients were included of whom 37% underwent an appropriate change in therapy. Groups 1 (67% and 2 (83% had high adherence compared to only 9% in group 3. At 6 months, 57% had achieved remission. More patients who underwent an appropriate change in therapy achieved remission, though this did not reach statistical significance (69% versus 49%; P=0.098. Conclusions. A trend towards increased remission rates was associated with appropriate changes in management following TDM results. Many patients with therapeutic IFX concentrations did not undergo an appropriate change in management, potentially reflecting a lack of available out-of-class options at the time of TDM or due to uncertainty of the meaning of the reported therapeutic range.

Cell transplantation with embryonic stem (ES) cell progeny requires immunological compatibility with host tissue. ‘Therapeutic cloning’ is a strategy to overcome this limitation by generating nuclear transfer (nt)ES cells that are genetically matched to an individual. Here we establish the feasibility of treating individual mice via therapeutic cloning. Derivation of 187 ntES cell lines from 24 parkinsonian mice, dopaminergic differentiation, and transplantation into individually matched host mice showed therapeutic efficacy and lack of immunological response.

However, data on the microbiological airway colonization at the time of eLVR are scarce, and there are no evidence-based recommendations regarding a rational antibiotic regimen.Objective: The aim of this study was to perform a clinical and microbiological analysis of COPD patients with advanced emphysema undergoing eLVR with endobronchial valves at a single German University hospital, 2012–2017.Patients and methods: Bronchial aspirates were obtained prior to eLVR and sent for microbiological analysis. Antimicrobial susceptibility testing of bacterial isolates was performed, and pathogen colonization was retrospectively compared with clinical parameters.Results: At least one potential pathogen was found in 47% (30/64 of patients. Overall, Gram-negative bacteria constituted the most frequently detected pathogens. The single most prevalent species were Haemophilus influenzae (9%, Streptococcus pneumoniae (6%, and Staphylococcus aureus (6%. No multidrug resistance was observed, and Pseudomonas aeruginosa occurred in <5% of samples. Patients without microbiological airway colonization showed more severe airflow limitation, hyperinflation, and chronic hypercapnia compared

Nausea and vomiting are the worst and the most prevalent complications experienced by 70-80% of patients. Complementary treatments including therapeutic touch are cost-effective and low-risk, independent nursing interventions. Present research aims at investigating the effect of therapeutic touch on the intensity of acute chemotherapy-induced vomiting in these patients. As a single-blind, randomized clinical trial, the present research was carried out on women with breast cancer undergoing chemotherapy in Isfahan, Iran. The subjects were divided into three groups of control, placebo, and intervention. The intervention was applied to each patient once for 20 min on the aura (human energy field) focusing on solar chakra. Data gathering instruments included demographic questionnaire and acute vomiting intensity scale. There was a significant difference among the three groups (and also after the intervention) (P touch was effective in reducing vomiting in the intervention group. However, the patients experienced lower-intensity vomiting which may be because of presence of a therapist and probably the reduced anxiety related to an additional intervention. So, further research is recommended considering the placebo group and employing another person in addition to the therapist, who is not skilled for this technique.

An increasing number of women are undergoing labiaplasty procedures; however, very little is known about the psychological factors that motivate women to seek out this procedure. To investigate the factors that influence women's decisions to undergo labiaplasty. Women seeking to undergo labiaplasty (n = 35) were compared with women who were not (n = 30). Standardized measures were employed to assess the patients' media exposure (television, the Internet, advertising, pornography), relationship quality, and psychological well-being. Women's motivations for deciding to undergo a labiaplasty procedure were characterized as "appearance," "functional," "sexual," or "psychological" motivations, with concerns about the labia's appearance being the most commonly reported motivation. Correspondingly, women seeking labiaplasty were significantly less satisfied with the appearance of their genitals than the comparison group (P media exposure and relationship status as important factors that influence women's decisions to undergo labiaplasty. 3 Risk. © 2016 The American Society for Aesthetic Plastic Surgery, Inc.

The purpose of this study was to explore the feasibility and preliminary efficacy of a therapeutic music video (TMV) intervention for adolescents and young adults (AYAs) undergoing stem-cell transplantation (SCT). Twelve AYAs (aged 11-24 years) were randomized to the TMV or an audio-book protocol. The TMV was designed to diminish symptom distress and improve coping, derived meaning, resilience, and quality of life by supporting AYAs in exploring thoughts and feelings. Six sessions with a board-certified music therapist were held twice a week for 3 weeks. The Adolescent Resilience Model guided the selection of a large, comprehensive battery of outcome measures. Major data collections occurred before admission, after intervention, and at 100 days after transplantation. Participants completed a brief set of measures at presession/postsessions 2, 4, and 6. Rates of consent, session completion, and questionnaire completion supported feasibility. Immediate follow-up measures suggest positive trends in the TMV group for hope, spirituality, confidence/mastery, and self-transcendence. Positive trends at 100 days include MOS, symptoms distress, defensive coping, spirituality, and self-transcendence. Therapeutic music video participants also demonstrated gains in quality of life. The TMV intervention may buffer the immediate after-effects of the stem-cell transplantation experience, and a larger study is warranted.

Full Text Available OBJECTIVE: Choline is related to phospholipid metabolism and is a marker for global ischaemia with a small reference range in healthy volunteers. The aim of our study was to characterize the early kinetics of plasma free choline in patients after cardiac arrest. Additionally, we investigated the potential of plasma free choline to predict neurological outcome. METHODS: Twenty patients admitted to our medical intensive care unit were included in this prospective, observational trial. All patients were enrolled between May 2010 and May 2011. They received post cardiac arrest treatment including mild therapeutic hypothermia which was initiated with a combination of cold fluid and a feedback surface cooling device according to current guidelines. Sixteen blood samples per patient were analysed for plasma free choline levels within the first week after resuscitation. Choline was detected by liquid chromatography-tandem mass spectrometry. RESULTS: Most patients showed elevated choline levels on admission (median 14.8 µmol/L; interquartile range; IQR 9.9-20.1 which subsequently decreased. 48 hours after cardiac arrest choline levels in all patients reached subnormal levels at a median of 4.0 µmol/L (IQR 3-4.9; p = 0.001. Subsequently, choline levels normalized within seven days. There was no significant difference in choline levels when groups were analyzed in relation to neurological outcome. CONCLUSIONS: Our data indicate a choline deficiency in the early postresucitation phase. This could potentially result in impaired cell membrane recovery. The detailed characterization of the early choline time course may aid in planning of choline supplementation trials. In a limited number of patients, choline was not promising as a biomarker for outcome prediction.

Because a traditional rendezvous (RV) technique implies stretching of the papilla, possibly leading to post-ERCP pancreatitis, an alternative duodenal RV technique was evaluated. The aim was to assess the effectiveness, safety, and amount of time spent performing duodenal RV versus traditional RV cannulation in orthotopic liver transplantation patients with a T-tube. We retrospectively reviewed data from a prospective ERCP database held by our university hospital. Twenty patients with a T-tube who had undergone ERCP for biliary adverse events after orthotopic liver transplantation were included. The successful cannulation rate, the amount of time spent performing cannulation, the post-ERCP pancreatitis rate, and hyperamylasemia 24 hours after the procedure were recorded. Successful cannulation was achieved by the duodenal RV technique in 9 of 10 patients (90%), taking 146 seconds (interquartile range 63-341 seconds) with a short learning curve effect. An unsuccessful duodenal RV procedure occurred because of the angulation of the hydrophilic tip of the guidewire while crossing the papilla, thus preventing cannulation. Successful cannulation was achieved by the traditional RV technique in all cases (N = 11), including the failed duodenal RV technique, taking 374 seconds (interquartile range 320-410 seconds) (P < .05 vs duodenal RV). However, no post-ERCP pancreatitis occurred after using the duodenal RV technique compared with 2 episodes of mild pancreatitis after using the traditional RV technique. Twenty-four hours after the procedure, the median amylasemia level was 84 IU/L (interquartile range 49-105 IU/L) and 265 IU/L (interquartile range 73-2945 IU/L) for the duodenal versus traditional RV techniques, respectively (P = not significant). In patients with a T-tube after liver transplantation, the duodenal RV technique was not associated with post-ERCP pancreatitis, presumably because of the reduction of stress on the major papilla.

Full Text Available Background: The advanced era of technological development in child health care has resulted in more pediatric procedures being performed in various settings. Millions of children undergo surgery every year which is a stressful event. Many nonpharmacological strategies are being used to manage the preoperative fear and anxiety in children. The current study aims to assess the effectiveness of multimodal preoperative preparation program (MPPP on children undergoing surgery in terms of its effect on the psychophysiological parameters. Objective: The aim of this study is to assess the effectiveness of MPPP on the psychophysiological parameters of children undergoing surgery. Materials and Methods: A quasi-experimental study was conducted in a selected multi-specialty hospital. Using the purposive sampling technique, a total of 110 children aged 8–12 years were assigned to nonintervention (n = 55 and intervention (n = 55 groups, respectively. The MPPP was administered to the intervention group. The children in the nonintervention group received the routine preoperative care. Child's fear and anxiety was assessed on admission, prior to shifting the child to operation theater (OT, 24 and 48 h after surgery, whereas child's pulse, respiration, blood pressure (BP, and oxygen saturation was assessed on admission, prior to shifting the child to OT, 6, 12, 24, and 48 h after surgery and pain was assessed at 24 and 48 h after surgery. Results: The mean fear and anxiety scores of children were significantly lower in the intervention group than that of nonintervention group (P 0.05. This study also found that there is a significant association between the psychophysiological parameters of children with the selected demographic variables (P < 0.05. A positive correlation was found between the psychological and physiological parameters of children undergoing surgery. Conclusion: The MPPP is effective on psychophysiological parameters of children undergoing

Patterson, Amy S

2016-10-01

This article explores the reasons for therapeutic pacifism among people living with HIV (PLHIVs) in urban Zambia. It contributes to a growing ethnography on global health, biosociality, and patient-provider dynamics. Therapeutic citizenship is a biopolitical citizenship that includes claims and ethical projects that emerge from techniques to control and manage bodies. In some contexts, therapeutic citizenship has included activism and claims-making against local, national, and international power brokers. This article investigates therapeutic citizenship in the specific context of impoverished urban Zambian compounds, sites of food insecurity, unemployment, and political exclusion, as well as targets for donor, NGO, and faith-based organisation projects and PLHIV support group proliferation. The article utilises data from participant observations at two Lusaka AIDS clinics, interviews, and focused discussions with support groups of PLHIVs. It argues that PLHIVs continuously negotiate subjectivities related to kinship, clientship, religious belief, and political citizenship in processes that complicate therapeutic citizenship. Rather than fostering participation in PLHIV support groups or challenging 'politics as usual' through activist claims-making to institutions of biopower, these processes lead to therapeutic pacifism.

2015-04-27

Endoscopic retrograde cholangiography (ERCP) is currently standard treatment for biliary drainage. Endoscopic ultrasound guided rendezvous (EUS-RV) is a novel method to overcome an unsuccessful biliary drainage procedure. Under endoscopic ultrasound guidance a guidewire is passed via a needle from the stomach or duodenum to the common bile duct and from there on to the duodenum enabling ERCP. With a relatively high rate of success EUS-RV should be considered as an alternative to biliary drainage and surgical intervention.

A prospective study was performed comparing the sensitivity of computed tomography, ultrasonography, and endoscopic retrograde cholangiopancreatography (ERCP) in the diagnosis of pancreatic disease. Forty patients with suspected pancreatic carcinoma, acute recurrent or chronic pancreatitis, and/or jaundice were studied. CT was the most sensitive study in evaluation of pancreatitis. ERCP was most accurate in evaluation of pancreatic malignancy. Ultrasonography was the least sensitive method in detecting pancreatic disease and dilatation of the extrahepatic biliary ducts. (orig.)

Full Text Available Objective: to evaluate the clinical usefulness of single-brush cytology performed at ERCP as initial method for detecting pancreatobiliary malignancy, ensuring a very close relationship between endoscopists, cytotechnicians, and cytopathologists. Study design: all 125 cytodiagnoses considered in this study correspond to the first brushing for each patient, collected by one of the three members of a fixed team of endoscopists in the presence of the same cytotechnician. Smears were fixed immediately with Merckofix® spray, stained with Papanicolau, and analyzed by the same cytopathologist in a laboratory exclusively devoted to gastrointestinal cytopathology located at the endoscopy unit. Results: of 125 cytological diagnoses 94 were considered benign, 4 suspicious, and 27 malignant. These findings were compared to the final diagnosis of 45 malignant and 80 benign lesions obtained either by surgical pathology or after at least one year of clinical follow-up. The comparison yielded 30 true positives, 78 true negatives, 1 false positive and 16 false negative results, which corresponds to a sensitivity, specificity, positive predictive value, negative predictive value, and accuracy of 65.2, 98.7, 96.8, 83, and 86.4%, respectively. Conclusion: results seem to confirm the usefulness of an effective team approach to ERCP-directed brush cytology for the diagnosis of pancreatobiliary malignancy. However, sensitivity continues to be rather low.Objetivo: evaluar la utilidad clínica de la citología con cepillo único durante la CPRE como método inicial de detección de los cánceres pancreaticobiliares, garantizando una relación muy cercana entre endoscopistas, citotécnicos y citopatólogos.

An elderly female was admitted with obstructive jaundice, secondary to an impacted 1.7 cm size stone in distal CBD. Cholangiogram obtained during ERCP revealed dilated biliary system with large, immobile stone at the lower end of CBD. A large size sphincterotomy was performed and stone extraction using biliary balloon / dormia basket attempted which was unsuccessful as the stone was impacted in distal CBD. Therefore, a plastic biliary stent of 9 cm/8.5 french size was inserted successfully to secure the biliary drainage. Patient improved clinically and discharged home on ursodeoxycholic acid. Four weeks later, she presented to emergency department with signs of cholangitis. An emergency ERCP was performed. The stent had migrated up completely into the left intra hepatic duct. In this session, the stone was extracted and biliary drainage secured. Migrated stent was removed later on by another ERCP procedure. (author)

As part of the clinical evaluation of image management and communications system (IMACS), the authors undertook a prospective study to compare conventional film versus digitized film viewed on a workstation. Twenty-five each of normal and abnormal endoscopic retrograde cholangiopancreatographic (ERCP) studies were digitized with a 1,684 x 2,048-pixel matrix and evaluated in a single-blind fashion on the workstation. The resulting interpretations were then compared with those resulting from interpretation of film (spot film and 100-mm photospot) images. They report that no significant differences were found in ability to see anatomic detail or pathology. A second study involved performing 10 ERCP studies in a lithotripsy suite equipped with biplane digital fluoroscopy. The digital video displays were comparable in quality to that of film. Progress is being made in using the IMACS for archiving and retrieval of all current ERCP images

This study aimed to compare the clinical outcomes of patients with advanced hilar cholangiocarcinoma (CC) who underwent photodynamic therapy (PDT) with either percutaneous transhepatic cholangioscopy (PTCS) or endoscopic retrograde cholangiopancreatography (ERCP). PDT has been proposed as a promising therapy for treatment of unresectable hilar CC that is resistant to conventional standard treatment. However, few studies have compared the delivery methods of PDT in unresectable hilar CC patients. Thirty-seven adult patients with advanced hilar CC were included in this study. Twenty-four patients treated with PTCS-directed PDT and 13 patients treated with ERCP-directed PDT were analyzed retrospectively. The PTCS- and ERCP-directed PDT groups were comparable with respect to age, gender, health status, pretreatment bilirubin levels, Bismuth type, and hilar CC stage. The length of hospital stay differed significantly (p hilar CC. Lower pre-PDT bilirubin levels were associated with longer survival in all patients.

Stone recurrence is a common late adverse event after ERCP in patients with common bile duct stones (CBDS). Duodenal-biliary reflux (DBR) is considered a major cause of CBDS recurrence. However, specific evidence is still lacking. To investigate the DBR rate in patients with recurrent CBDS after ERCP. A prospective case-control study. A tertiary center. During follow-up, patients with a history of either recurrent CBDS (recurrence group) or nonrecurrent CBDS (control group) were invited to participate in the study. All patients had previously undergone successful CBDS removal by ERCP. Patients in the control group were matched with the recurrence group by age and gender in a 1:1 ratio. Patients with gallbladder stones, hepatolithiasis, remnant CBDS, CBD strictures, or stents were excluded. Standard barium meal examination, MRCP, and enhanced abdominal CT. DBR. Thirty-two patients with a history of recurrent CBDS and 32 matched control subjects were enrolled. Baseline characteristics and parameters regarding the first ERCP were comparable between the 2 groups. The DBR rate was significantly higher in the recurrent than in the control group (68.8% vs 15.6%, P < .001). Multivariate analysis indicated that DBR (OR, 9.59; 95% CI, 2.65-34.76) and acute distal CBD angulation (OR, 5.48; 95% CI, 1.52-19.78) were independent factors associated with CBDS recurrence. DBR rates in patients with no, single, or multiple recurrences were 15.6%, 60.9%, and 88.9%, respectively (P < .001). Intrahepatic bile duct reflux was more common in patients with multiple recurrences. Small sample size. DBR is correlated with CBDS recurrence in patients who had previously undergone ERCP. DBR and acute distal CBD angulation are 2 independent risk factors related to stone recurrence. ( NCT02329977.) Copyright © 2015 American Society for Gastrointestinal Endoscopy.

Mizushima, Taichi; Tirador, Kathleen A; Miyamoto, Hiroshi

2017-03-01

Patients with non-muscle-invasive or muscle-invasive bladder cancer undergoing surgery and currently available conventional therapy remain having a high risk of tumor recurrence or progression, respectively. Novel targeted molecular therapy is therefore expected to improve patient outcomes. Meanwhile, substantially higher incidence of bladder cancer in men has prompted research on androgen-mediated androgen receptor (AR) signaling in this malignancy. Indeed, preclinical evidence has suggested that AR signaling plays an important role in urothelial carcinogenesis and tumor outgrowth as well as resistance to some of the currently available conventional non-surgical therapies. Areas covered: We summarize and discuss available data suggesting the involvement of AR and its potential downstream targets in the development and progression of bladder cancer. Associations between AR signaling and sensitivity to cisplatin/doxorubicin or bacillus Calmette-Guérin treatment are also reviewed. Expert opinion: AR activation is likely to correlate with the promotion of urothelial carcinogenesis and cancer outgrowth as well as resistance to conventional therapies. Molecular therapy targeting the AR may thus provide effective chemopreventive and therapeutic approaches for urothelial cancer. Accordingly, bladder cancer can now be considered as an endocrine-related neoplasm. Clinical application of various anti-AR therapies available for AR-dependent prostate cancer to bladder cancer patients is anticipated.

The analysis of DNA microarray and proteomic data, and the subsequent integration into functional expression sets, provides a circuit map of the hierarchical cellular networks responsible for sustaining the viability and environmental competitiveness of cancer cells, that is, their robust systematics. These technologies can be used to 'snapshot' the unique patterns of molecular derangements and modified interactions in cancer, and allow for strategic selection of therapeutics that best match the individual profile of the tumour. This review highlights technology that can be used to selectively disrupt critical molecular targets and describes possible vehicles to deliver the synthesised molecular therapeutics to the relevant cellular compartments of the malignant cells. RNA interference (RNAi) involves a group of evolutionarily conserved gene silencing mechanisms in which small sequences of double-stranded RNA or intrinsic antisense RNA trigger mRNA cleavage or translational repression, respectively. Although RNAi molecules can be synthesised to 'silence' virtually any gene, even if upregulated, a mechanism for selective delivery of RNAi effectors to sites of malignant disease remains challenging. The authors will discuss gene-modified conditionally replicating viruses as candidate vehicles for the delivery of RNAi.

In the last part, a comparative degradation study was performed between the anionic and cationic micellar assemblies in the presence of two model enzymes, and electrostatic interaction-mediated preferential hydrolysis was demonstrated between the oppositely-charged enzyme-micelle pairs. These findings may be of potential significance toward the design of charge-mediated enzyme-responsive nanomaterials that are capable of undergoing environmentally-triggered therapeutic release, disassembly or morphological alterations under selective enzyme conditions.

PYTHIOSIS: A THERAPEUTIC APPROACH

Directory of Open Access Journals (Sweden)

C. M. C. Falcão

2015-10-01

Full Text Available Pythiosis, a disease caused by the oomycete Pythium insidiosum, often presents inefficient response to chemotherapy. It is a consensus that, in spite the several therapeutic protocols, a combination of surgery, chemotherapy and immunotherapy should be used. Surgical excision requires the removal of the entire affected area, with a wide margin of safety. The use of antifungal drugs has resulted in variable results, both in vitro and in vivo, and presents low therapeutic efficiency due to differences in the agent characteristics, which differ from true fungi. Immunotherapy is a non-invasive alternative for the treatment of pythiosis, which aims at modifying the immune response of the host, thereby producing an effective response to the agent. Photodynamic therapy has emerged as a promising technique, with good activity against P. insidiosum in vitro and in vivo. However, more studies are necessary to increase the efficiency of the current treatment protocols and consequently improve the cure rates. This paper aims to conduct a review covering the conventional and recent therapeutic methods against P. insidiosum infections

This repeated-session design sought to answer questions about the effectiveness of therapeutic touch in reduction of stress for 23 individuals following a natural disaster. In addition, methodological issues related to the average length of time for a therapeutic-touch treatment and a method of documenting the nonverbal interaction between subject and toucher were investigated. Findings indicate that stressed people report themselves to be less stressed following therapeutic touch (p = .05). Time of therapeutic-touch intervention varied significantly between the touchers, with a range of 6.8 to 20 minutes. Qualitative data examining the interaction of toucher and subject raised a number of questions that require further study.

Therapeutic ultrasound

Crum, Lawrence A

2004-01-01

The use of ultrasound in medicine is now quite commonplace, especially with the recent introduction of small, portable and relatively inexpensive, hand-held diagnostic imaging devices. Moreover, ultrasound has expanded beyond the imaging realm, with methods and applications extending to novel therapeutic and surgical uses. These applications broadly include: tissue ablation, acoustocautery, lipoplasty, site-specific and ultrasound mediated drug activity, extracorporeal lithotripsy, and the enhancement of natural physiological functions such as wound healing and tissue regeneration. A particularly attractive aspect of this technology is that diagnostic and therapeutic systems can be combined to produce totally non-invasive, imageguided therapy. This general lecture will review a number of these exciting new applications of ultrasound and address some of the basic scientific questions and future challenges in developing these methods and technologies for general use in our society. We shall particularly emphasize the use of High Intensity Focused Ultrasound (HIFU) in the treatment of benign and malignant tumors as well as the introduction of acoustic hemostasis, especially in organs which are difficult to treat using conventional medical and surgical techniques.

All reported twins after IVF with double-embryo transfer (n = 1,982) and their mothers (n = 991) and all mothers (n = 921) who gave birth to two IVF singletons (n = 1,842). None. Maternal and neonatal outcomes including severe neonatal morbidity. Preterm birth, very preterm birth, low birth weight, very low birth weight, and small for gestational age were dramatically increased for IVF twins compared with two IVF singletons with the same mother, with adjusted odds ratios from 4 to 16. Significantly higher rates of respiratory complications, sepsis, and jaundice were detected among the IVF twins. Significantly higher rates of preeclampsia, preterm premature rupture of the membranes, and cesarean section were observed for IVF twin pregnancies. The neonatal and maternal outcomes were dramatically better for women undergoing two IVF singleton pregnancies compared with one IVF twin pregnancy after double-embryo transfer. These results support single-embryo transfer to minimize the risks associated with twin pregnancies. Copyright © 2013 American Society for Reproductive Medicine. Published by Elsevier Inc.

Therapeutic radionuclides: Making the right choice

International Nuclear Information System (INIS)

Srivastava, S.C.

1996-01-01

Recently, there has been a resurgence of interest in nuclear medicine therapeutic procedures. Using unsealed sources for therapy is not a new concept; it has been around since the beginnings of nuclear medicine. Treatment of thyroid disorders with radioiodine is a classic example. The availability of radionuclides with suitable therapeutic properties for specific applications, as well as methods for their selective targeting to diseased tissue have, however, remained the main obstacles for therapy to assume a more widespread role in nuclear medicine. Nonetheless, a number of new techniques that have recently emerged, (e.g., tumor therapy with radiolabeled monoclonal antibodies, treatment of metastatic bone pain, etc.) appear to have provided a substantial impetus to research on production of new therapeutic radionuclides. Although there are a number of new therapeutic approaches requiring specific radionuclides, only selected broad areas will be used as examples in this article

The aim of this study was to prospectively assess women's pain during rigid and flexible diagnostic cystoscopy and afterwards during a one-week follow-up. Prospective, multi-institutional trial analyzing numeric rating scales (NRS) of women undergoing diagnostic cystoscopy. Pain categories: no (0 points), mild (1-3), moderate (4-6) and severe pain (7-10). Assessing of pain before, during cystoscopy, and at day 1, 4 and 7 of follow-up. A total of 150 women undergoing rigid (N.=85) or flexible (N.=65) diagnostic cystoscopy were analyzed. Women undergoing flexible cystoscopy were more frequently pain-free (64.6% vs. 40%, P=0.003) and experienced mild pain less frequently (27.7% vs. 52.9% vs. P=0.002). No significant differences were noted among moderate (6.2% vs. 5.9%, P=0.95) and severe pain (1.5% vs. 1.2%, P=0.85). Patients undergoing their first (P=0.14) and repeat cystoscopy (P=0.08) had similar pain perception. In multivariate logistic regression analyses, women undergoing flexible cystoscopy had a 2.6 increased chance of being pain-free (OR=2.6, CI: 1.28-5.11, P=0.08) and their odds of experiencing mild pain were significantly lower (OR=0.34, CI: 0.17-0.71, P=0.004). The likelihood of experiencing moderate (OR=1.1, CI: 0.28- 4.4, P=0.83) or severe pain (OR=2.42, CI: 0.11-51.79, P=0.57) differed insignificantly. Rigid and flexible cystoscopies were well-tolerated by most women. However, flexible cystoscopy was associated with a higher likelihood of being pain-free and lower chances of experiencing mild pain. Patients' previous experience with cystoscopy did not influence pain perception.

To determine if dogs that undergo laparotomy for cholecystectomy suffer from a greater number or magnitude of perianesthetic complications, including hypotension, hypothermia, longer recovery time, and lower survival rate, than dogs that undergo laparotomy for hepatic surgery without cholecystectomy. Retrospective cohort study. One hundred and three dogs, anesthetised between January 2007 and October 2011. The variables collected from the medical record included age, weight, gender, surgical procedure, pre-operative bloodwork, American Society of Anesthesiologists (ASA) status, emergency status, total bilirubin concentration, anesthetic agents administered, body temperature nadir, final body temperature, hypotension, duration of hypotension, blood pressure nadir, intraoperative drugs, anesthesia duration, surgery duration, time to extubation, final diagnosis, days spent in the intensive care unit (ICU), total bill, survival to discharge, and survival to follow-up. No significant difference in body temperature nadir, final temperature, presence of hypotension, duration of hypotension, blood pressure nadir, the use of inotropes, or final outcome was found between dogs undergoing cholecystectomy and dogs undergoing exploratory laparotomy for other hepatic disease. Dogs that had cholecystectomy had longer anesthesia durations and longer surgery durations than dogs that did not have cholecystectomy. No significant differences existed for temperature nadir (34.8 versus 35.3°C; non-cholecystectomy versus cholecystectomy), final temperature (35.6 versus 35.9°C), time to extubation (30 versus 49 minutes), duration of hypotension (27 versus 21 minutes), or MAP nadir (56 versus 55 mmHg). Hypotension occurred in 66% and 74% and inotropes were used in 64% and 53%, for non-cholecystectomy and cholecystectomy patients, respectively. Dogs that underwent cholecystectomies did not suffer a greater number of anesthesia complications than did dogs undergoing hepatic surgery without

[New guidelines on chronic pancreatitis : interdisciplinary treatment strategies].

Lerch, M M; Bachmann, K A; Izbicki, J R

2013-02-01

Chronic pancreatitis is a common disorder associated with significant morbidity and mortality. Interdisciplinary consensus guidelines have recently updated the definitions and diagnostic criteria for chronic pancreatitis and provide a critical assessment of therapeutic procedures. Diagnostic imaging relies on endoscopic ultrasound (EUS) as the most sensitive technique, whereas computed tomography (CT) and magnetic resonance imaging (MRI)/magnetic resonance cholangiopancreatography (MRCP) remain a frequent preoperative requirement. Endoscopic retrograde cholangiopancreatography (ERCP) is now used mostly as a therapeutic procedure except for the differential diagnosis of autoimmune pancreatitis. Complications of chronic pancreatitis, such as pseudocysts, duct stricture and intractable pain can be treated with endoscopic interventions as well as open surgery. In the treatment of pseudocysts endoscopic drainage procedures now prevail while pain treatment has greater long-term effectiveness following surgical procedures. Currently, endocopic as well as surgical treatment of chronic pancreatitis require an ever increasing degree of technical and medical expertise and are provided increasingly more often by interdisciplinary centres. Surgical treatment is superior to interventional therapy regarding the outcome of pain control and duodenum-preserving pancreatic head resection is presently the surgical procedure of choice.

Full Text Available Aims. We here investigated the association of different types of periampullary diverticula (PAD with pancreaticobiliary disease and with technical success of endoscopic retrograde cholangiopancreatography (ERCP. Methods. A total of 850 consecutive patients who underwent their first ERCP were entered into a database. Of these patients, 161 patients (18.9% had PAD and the age- and sex-matched control group comprised 483 patients. Results. PAD was correlated with common bile duct (CBD stones (59.6% versus 35.0% in controls; P=0.008 and negatively correlated with periampullary malignancy (6.8% versus 21.5% in controls; P=0.004. The acute pancreatitis was more frequent (62.5% in patients with PAD type 1 followed by PAD type 2 (28.9%, P=0.017 and type 3 (28.0%, P=0.006. No significant differences were observed in successful cannulation rate and post-ERCP complications among the 3 types of PAD. Type 1 PAD patients had less recurrence of CBD stones than did the patients who had type 2 or type 3 PAD (53.8% versus 85.7%; P=0.043. Conclusions. PAD, especially type 1 PAD, is associated with an increased acute pancreatitis as well as occurrence and recurrence of CBD stones. PAD during an ERCP should not be considered as an obstacle to a successful cannulation.

Ultrasonography has proven to be quite effective in differentiating hepatocellular from obstructive cause of jaundice in various studies. This study was conducted with the aim to determine the efficacy of ultrasonography and Endoscopic Retrograde Cholangio-Pancreatography (ERCP) in the diagnosis of obstructive reason of jaundice. Methods: In this descriptive case series, 200 patients with >15 years age of either gender with cholestatic liver enzymes were included, i.e., those patients who had an ultrasound prior to ERCP at the department of gastroenterology of Patel Hospital, Karachi. Patients known to have liver disease with cholestatic jaundice had imaging other than ultrasound were excluded. The results of ultrasonography and ERCPs were compared in particularly looking for the cause of obstruction. Results: Out of total 200 patients, mean age was 41.22+-12.46 years with 107 (53.5 percent) females. Ability of ultrasound in correctly diagnosing obstructive reason for stone CBD was found to be 72.5 percent, dilated CBD without reason 41.7 percent, proximal obstruction, 63.15 percent, distal CBD obstruction 60 percent, and sludge 66.7 percent. Overall ability of ultrasound in correctly diagnosing the cause of obstruction was 64.17 percent. Conclusion: Ultrasound is recommended as the initial examination, which provides a guide to choose patients for either a more advanced non-invasive imaging like MRCP or to an invasive procedure like ERCP.

Background Platelet transfusions are used in modern clinical practice to prevent and treat bleeding in thrombocytopenic patients with bone marrow failure. Although considerable advances have been made in platelet transfusion therapy in the last 40 years, some areas continue to provoke debate, especially concerning the use of prophylactic platelet transfusions for the prevention of thrombocytopenic bleeding. This is an update of a Cochrane review first published in 2004 and updated in 2012 that addressed four separate questions: therapeutic-only versus prophylactic platelet transfusion policy; prophylactic platelet transfusion threshold; prophylactic platelet transfusion dose; and platelet transfusions compared to alternative treatments. We have now split this review into four smaller reviews looking at these questions individually; this review is the first part of the original review. Objectives To determine whether a therapeutic-only platelet transfusion policy (platelet transfusions given when patient bleeds) is as effective and safe as a prophylactic platelet transfusion policy (platelet transfusions given to prevent bleeding, usually when the platelet count falls below a given trigger level) in patients with haematological disorders undergoing myelosuppressive chemotherapy or stem cell transplantation. Search methods We searched for randomised controlled trials (RCTs) in the Cochrane Central Register of Controlled Trials (Cochrane Library 2015, Issue 6), MEDLINE (from 1946), Embase (from 1974), CINAHL (from 1937), the Transfusion Evidence Library (from 1950) and ongoing trial databases to 23 July 2015. Selection criteria RCTs involving transfusions of platelet concentrates prepared either from individual units of whole blood or by apheresis, and given to prevent or treat bleeding in patients with malignant haematological disorders receiving myelosuppressive chemotherapy or undergoing HSCT. Data collection and analysis We used standard methodological procedures

Monroe, Carolyn Magdalen

2009-06-01

To better understand how Therapeutic Touch can be used in today's health care arena, this integrative literature review will examine current research that will help answer the question, Does Therapeutic Touch reduce pain? An extensive search was conducted of the online databases MEDLINE, CINAHL, Cochrane Library, EMBASE, PsychLIT, and PubMed to retrieve research articles published from 1997 to 2007. Seven studies that were conducted between 1997 and 2004 were found and only five of the seven were included as pertinent evidence to answer the question. All of the research that was reviewed to answer whether Therapeutic Touch could significantly reduce pain revealed a majority of statistically significant positive results for implementing this intervention. Because there are no identified risks to Therapeutic Touch as a pain relief measure, it is safe to recommend despite the limitations of current research. Therapeutic Touch should be considered among the many possible nursing interventions for the treatment of pain.

β-Elemene, a compound found in an herb used in traditional Chinese medicine, has shown promising anti-cancer effects against a broad spectrum of tumors. The mechanism by which β-elemene kills cells remains unclear. The aim of the present study is to investigate the anti-tumor effect of β-elemene on human gastric cancer cells and the molecular mechanism involved. β-Elemene inhibited the viability of human gastric cancer MGC803 and SGC7901 cells in a dose-dependent manner. The suppression of cell viability was due to the induction of apoptosis. A robust autophagy was observed in the cells treated with β-elemene; it was characterized by the increase of punctate LC3 dots, the cellular morphology, and the increased levels of LC3-II protein. Further study showed that β-elemene treatment up-regulated Atg5-Atg12 conjugated protein but had little effect on other autophagy-related proteins. PI3K/Akt/mTOR/p70S6K1 activity was inhibited by β-elemene. Knockdown of Beclin 1 with small interfering RNA, or co-treatment with the autophagy inhibitor, 3-methyladenine or chlorochine enhanced significantly the antitumor effects of β-elemene. Our data provides the first evidence that β-elemene induces protective autophagy and prevents human gastric cancer cells from undergoing apoptosis. A combination of β-elemene with autophagy inhibitor might thus be a useful therapeutic option for advanced gastric cancer

To determine if the use of thigh-high compression stockings could decrease the incidence of cerebral desaturation events (CDEs) in patients with a body mass index (BMI) of 30 kg/m(2) or greater undergoing shoulder arthroscopy in the beach-chair position (BCP). Between December 2013 and May 2014, 23 patients aged 18 years or older with a BMI of 30 kg/m(2) or greater undergoing shoulder arthroscopy in the BCP were monitored intraoperatively using near-infrared spectroscopy while wearing thigh-high compression stockings. Data obtained on these patients were compared with data from a previous cohort at our institution comprising 24 patients with a BMI of 30 kg/m(2) or greater who underwent elective shoulder arthroscopy in the BCP with the same monitoring but without wearing compression stockings. The incidence of CDEs was identified in each group. The incidence of CDEs in the group with compression stockings was 4% (1 of 23) compared with 18% (7 of 24) in the group without compression stockings (P = .048). There were no statistically significant differences in mean age (53.0 years v 53.3 years, P = .91), mean BMI (34.5 kg/m(2)v 36.2 kg/m(2), P = .21), or various medical comorbidities between the treatment group and control group. There was a significant difference in the operative time between the treatment group (156.6 minutes) and control group (94.1 minutes) (P arthroscopy in the BCP. Level IV, therapeutic case series.

The therapeutic relationship: historical development and contemporary significance.

Science.gov (United States)

O'Brien, A J

2001-04-01

The therapeutic relationship is a concept held by many to be fundamental to the identity of mental health nurses. While the therapeutic relationship was given formal expression in nursing theory in the middle of the last century, its origins can be traced to attendants' interpersonal practices in the asylum era. The dominance of medical understandings of mental distress, and the working-class status of asylum attendants, prevented the development of an account of mental health nursing based on attendants' relationships with asylum inmates. It was left to Peplau and other nursing theorists to describe mental health nursing as a therapeutic relationship in the 1940s and later. Some distinctive features of colonial life in New Zealand suggest that the ideal of the attendant as the embodiment of bourgeoisie values seems particularly unlikely to have been realized in the New Zealand context. However, New Zealand literature from the 20th century shows that the therapeutic relationship, as part of a general development of a therapeutic discourse, came to assume a central place in conceptualizations of mental health nursing. While the therapeutic relationship is not by itself a sufficient basis for professional continuity, it continues to play a fundamental role in mental health nurses' professional identity. The way in which the therapeutic relationship is articulated in the future will determine the meaning of the therapeutic relationship for future generations of mental health nurses.

Cardiac disease frequently occurs in children with chronic kidney disease (CKD) undergoing dialysis (DI), but it is not well studied in patients undergoing conservative treatment (CT). The aim of our study was to use echocardiography to analyze and compare the cardiac involvement of children with CKD undergoing DI or CT. Seventy-one children with CKD were included; 41 undergoing DI and 30 undergoing CT. There were 33 controls. Measurements of arterial pressure and structural and functional echocardiographic variables were obtained; the children were followed up for 18 months. Tests of comparison and multiple regression were used; significant if P < 0.05. Arterial hypertension (AH) was present in 37 of 71 (52%) children with CKD: 27 (65.8%) in DI and 10 (33.3%) in CT (X2 = 8.7; P = 0.003). An abnormal left ventricular geometric pattern was present in 37/41 (90.3%) undergoing DI, 33 had left ventricular hypertrophy (LVH), and in 14/30 (46.7%) undergoing CT, 5 had LVH. Ejection fraction was normal in all groups; diastolic function alteration (DFA) occurred in 28/41 (68.3%) children on DI and in 10/30 (33.3%) on CT (X2 = 9.2; P = 0.002). For children with CKD, DI (P = 0.002) and hypertension (P = 0.04) were associated with LVH; among those on DI, only AH was associated with LVH (P = 0.02). During the follow-up, 18 (43.9%) children undergoing DI had at least one cardiovascular event. Children with CKD undergoing CT had less cardiac involvement than those undergoing DI. LVH was associated with DI and AH in all children with CKD and with AH in those on DI.

Therapeutic proteins can face substantial challenges to their activity, requiring protein modification or use of a delivery vehicle. Nanoparticles can significantly enhance delivery of encapsulated cargo, but traditional small molecule carriers have some limitations in their use for protein delivery. Nanoparticles made from protein have been proposed as alternative carriers and have benefits specific to therapeutic protein delivery. This review describes protein nanoparticles made by self-assembly, including protein cages, protein polymers, and charged or amphipathic peptides, and by desolvation. It presents particle fabrication and delivery characterization for a variety of therapeutic and model proteins, as well as comparison of the features of different protein nanoparticles.

Breviscapine injection is a Chinese herbal medicine standardized product extracted from Erigeron breviscapus (Vant.) Hand.-Mazz. It has been widely used for treating cardiovascular and cerebrovascular diseases. However, the therapeutic time window and the action mechanism of breviscapine are still unclear. The present study was designed to investigate the therapeutic time window and underlying therapeutic mechanism of breviscapine injection against cerebral ischemic/reperfusion injury. Sprague-Dawley rats were subjected to middle cerebral artery occlusion for 2h followed by 24h of reperfusion. Experiment part 1 was used to investigate the therapeutic time window of breviscapine. Rats were injected intravenously with 50mg/kg breviscapine at different time-points of reperfusion. After 24h of reperfusion, neurologic score, infarct volume, brain water content and serum level of neuron specific enolase (NSE) were measured in a masked fashion. Part 2 was used to explore the therapeutic mechanism of breviscapine. 4-Hydroxy-2-nonenal (4-HNE), 8-hydroxyl-2'- deoxyguanosine (8-OHdG) and the antioxidant capacity of ischemia cortex were measured by ELISA and ferric-reducing antioxidant power (FRAP) assay, respectively. Immunofluorescence and western blot analysis were used to analyze the expression of nuclear factor erythroid 2-related factor 2 (Nrf2) and heme oxygenase-1 (HO-1). Part 1: breviscapine injection significantly ameliorated neurologic deficit, reduced infarct volume and water content, and suppressed the levels of NSE in a time-dependent manner. Part 2: breviscapine inhibited the increased levels of 4-HNE and 8-OHdG, and enhanced the antioxidant capacity of cortex tissue. Moreover, breviscapine obviously raised the expression of Nrf2 and HO-1 proteins after 24h of reperfusion. The therapeutic time window of breviscapine injection for cerebral ischemia/reperfusion injury seemed to be within 5h after reperfusion. By up-regulating the expression of Nrf2/HO-1 pathway

Gudiña, Eduardo J; Rangarajan, Vivek; Sen, Ramkrishna; Rodrigues, Lígia R

2013-12-01

Biosurfactants have recently emerged as promising molecules for their structural novelty, versatility, and diverse properties that are potentially useful for many therapeutic applications. Mainly due to their surface activity, these molecules interact with cell membranes of several organisms and/or with the surrounding environments, and thus can be viewed as potential cancer therapeutics or as constituents of drug delivery systems. Some types of microbial surfactants, such as lipopeptides and glycolipids, have been shown to selectively inhibit the proliferation of cancer cells and to disrupt cell membranes causing their lysis through apoptosis pathways. Moreover, biosurfactants as drug delivery vehicles offer commercially attractive and scientifically novel applications.

Zuckerman, Jonathan E; Davis, Mark E

2013-11-01

Nanoparticles are an enabling technology for the creation of tissue-/cell-specific therapeutics that have been investigated extensively as targeted therapeutics for cancer. The kidney, specifically the glomerulus, is another accessible site for nanoparticle delivery that has been relatively overlooked as a target organ. Given the medical need for the development of more potent, kidney-targeted therapies, the use of nanoparticle-based therapeutics may be one such solution to this problem. Here, we review the literature on nanoparticle targeting of the glomerulus. Specifically, we provide a broad overview of nanoparticle-based therapeutics and how the unique structural characteristics of the glomerulus allow for selective, nanoparticle targeting of this area of the kidney. We then summarize literature examples of nanoparticle delivery to the glomerulus and elaborate on the appropriate nanoparticle design criteria for glomerular targeting. Finally, we discuss the behavior of nanoparticles in animal models of diseased glomeruli and review examples of nanoparticle therapeutic approaches that have shown promise in animal models of glomerulonephritic disease.

To develop a feasible model for monitoring short-term outcome of clinical care trajectories for hospitals in the Netherlands using data obtained from hospital information systems for identifying hospital variation. Retrospective analysis of collected data from hospital information systems combined with clinical indicator definitions to define and compare short-term outcomes for three gastrointestinal pathways using the concept of Textbook Outcome. 62 Dutch hospitals. 45 848 unique gastrointestinal patients discharged in 2015. A broad range of clinical outcomes including length of stay, reintervention, readmission and doctor-patient counselling. Patients undergoing endoscopic retrograde cholangiopancreatography (ERCP) for gallstone disease (n=4369), colonoscopy for inflammatory bowel disease (IBD; n=19 330) and colonoscopy for colorectal cancer screening (n=22 149) were submitted to five suitable clinical indicators per treatment. The percentage of all patients who met all five criteria was 54%±9% (SD) for ERCP treatment. For IBD this was 47%±7% of the patients, and for colon cancer screening this number was 85%±14%. This study shows that reusing data obtained from hospital information systems combined with clinical indicator definitions can be used to express short-term outcomes using the concept of Textbook Outcome without any excess registration. This information can provide meaningful insight into the clinical care trajectory on the level of individual patient care. Furthermore, this concept can be applied to many clinical trajectories within gastroenterology and beyond for monitoring and improving the clinical pathway and outcome for patients. © Article author(s) (or their employer(s) unless otherwise stated in the text of the article) 2018.

2007-01-01

The purpose of this study was to evaluate the therapeutic efficacy of the cooking group from the burn survivors' perspective. By incorporating concepts of kitchen skills, energy conservation, and desensitization techniques, the cooking group can assist patients with the functional use of their hands, standing tolerance, return to former vocational activities, and socialization with other patients. A questionnaire was developed based on commonly expressed benefits of cooking group. Areas of interest included decreasing anxiety in the kitchen, distraction from their burns, socializing with other burn survivors, and the physical benefits of participating in the group. The results of this study indicate that participants regard the therapeutic cooking group as a valuable treatment modality that effectively combines functional activities with socialization to decrease burn related anxiety and increase motion in a supportive environment for patients with burns.

To analyze perceived health status and other health-related indicators in the adult population in Granada (Spain) undergoing an eviction process from their homes, whether rented or owned, in comparison with health indicators in the general adult population in Andalusia. A cross-sectional survey was administered by trained staff. The survey included instruments from the Andalusian Health Survey 2011 for measuring variables related to physical and mental health, as well as health-related habits. We compared the results with those obtained from the Andalusian general population through the Andalusian Health Survey. A bivariate analysis using the χ2 test and a multivariate logistic regression analysis were conducted. We obtained a total sample of 205 people in the process of eviction. A total of 59.5% (n=122) were women, and 40.5% (n=83) were men. Participants were more likely to have poor health (odds ratio [OR]: 12.63, 95% confidence interval [95%CI]: 8.74-18.27), have cardiovascular diseases (OR: 3.08; 95%CI: 1.54- 6.16), or to smoke (OR: 1.68; 95% CI: 1.21-2.33) compared with the Andalusian general population. Most of the health indicators analyzed showed a worse outcome for women undergoing an eviction process. Our results suggest that, in the current context of economic crisis, people undergoing a process of eviction in Granada and its metropolitan area show poorer health than the Andalusian general population. Further research is needed on health and evictions from different methodological approaches, for a better understanding of the topic. Copyright © 2015 SESPAS. Published by Elsevier Espana.

Childhood obesity is high on the global public health agenda. Although risk factors are well known, the influence of social risk on the therapeutic outcome of lifestyle intervention is poorly examined. This study aims to investigate the influence of migration background, low education, and parental unemployment. 62,147 patients participated in multidimensional lifestyle intervention programs in 179 pediatric obesity centers. Data were collected using standardized software for longitudinal multicenter documentation. 12,305 (19.8%) attended care for 6-24 months, undergoing an intensive therapy period and subsequent follow-ups for up to 3 years. A cumulative social risk score was calculated based on different risk indicators. Migration background, low education, and parental employment significantly influenced the outcome of lifestyle intervention. The observed BMI-SDS reduction was significantly higher in the subgroup with low social risks factors (Δ BMI-SDS -0.19) compared to those presenting moderate (Δ BMI-SDS -0.14) and high social risk (Δ BMI-SDS -0.11). Our data underline the effect of children's social setting on the outcome of multidimensional lifestyle intervention. The presence of a high social risk burden is a negative predictor for successful weight loss. Specific therapeutic programs need to be developed for disadvantaged children and adolescents.

Full Text Available Therapeutic platelet reduction is an effective modality for the reduction of platelet count in patients with treatment of extreme thrombocytosis resulting from a variety of primary and secondary causes of thrombocytosis, which may be associated with thrombotic or hemorrhagic complications of varying degrees. These cases when symptomatic fall into the ASFA Category II indication for therapeutic platelet apheresis procedure. Here, we report a case of postsplenectomy secondary thrombocytosis presenting with extremely high platelet counts and subsequent thrombosis in the shunt and successful treatment after therapeutic platelet reduction. The case is being presented to bring forth the fact that therapeutic platelet reduction is an easy procedure that gives quick and good results and also to bring to the attention of transfusion specialists an associated but as yet unreported procedural finding.

Research was conducted to gain insight into potential clients' decisions to undergo plastic surgery, their perception of benefits and risks, their judgment of outcomes, and their selection of a plastic surgeon. Semistructured, open-ended interviews were conducted with 60 people who expressed interest in plastic surgery. Qualitative analysis revealed their "mental models" regarding influences on their decision to undergo plastic surgery and their choice of a surgeon. Interview results were used to design a Web-based survey in which 644 individuals considering plastic surgery responded. The desire for change was the most direct motivator to undergo plastic surgery. Improvements to physical well-being were related to emotional and social benefits. When prompted about risks, participants mentioned physical, emotional, and social risks. Surgeon selection was a critical influence on decisions to undergo plastic surgery. Participants gave considerable weight to personal consultation and believed that finding the "right" plastic surgeon would minimize potential risks. Findings from the Web-based survey were similar to the mental models interviews in terms of benefit ratings but differed in risk ratings and surgeon selection criteria. The mental models interviews revealed that interview participants were thoughtful about their decision to undergo plastic surgery and focused on finding the right plastic surgeon.

RNAi Therapeutics in Autoimmune Disease

Seunghee Cha

2013-03-01

Full Text Available Since the discovery of RNA interference (RNAi, excitement has grown over its potential therapeutic uses. Targeting RNAi pathways provides a powerful tool to change biological processes post-transcriptionally in various health conditions such as cancer or autoimmune diseases. Optimum design of shRNA, siRNA, and miRNA enhances stability and specificity of RNAi-based approaches whereas it has to reduce or prevent undesirable immune responses or off-target effects. Recent advances in understanding pathogenesis of autoimmune diseases have allowed application of these tools in vitro as well as in vivo with some degree of success. Further research on the design and delivery of effectors of RNAi pathway and underlying molecular basis of RNAi would warrant practical use of RNAi-based therapeutics in human applications. This review will focus on the approaches used for current therapeutics and their applications in autoimmune diseases, including rheumatoid arthritis and Sjögren’s syndrome.

The aim of this study was to evaluate the changes in salivary gland function in patients with chronic renal failure (CRF) undergoing hemodialysis. The group consisted of 23 patients with CRF (13 female, 10 male; mean age: 40±13 yr) and 14 healthy control subjects (mean age: 40±13 yr). All underwent dynamic salivary gland scintigraphy with gustatory stimulation. After intravenous administration of 99m Tc pertechnetate, first, perfusion images at 2 seconds per frame were acquired for 1 minute, then dynamic images at 1 minute per frame were acquired for 45 minutes. At 30 minutes after injection , 10 ml lemon juice was given for 15 minutes as a gustatory stimulus. We obtained time-activity curves derived from regions of interest centered over the four major salivary glands. The following functional indices were calculated for each gland: the time of maximum radioactivity (T max ) for the prestimulated period, the time of minimum radioactivity (T min ), as an indicator of velocity of secretion after stimulation, and the Lem E 5 % value as an indicator of the secretion function. When the patients with CRF undergoing hemodialysis were compared to the controls, there were statistically significant differences in T max , T min and Lem E 5 % values for bilateral parotid glands, and T min values for bilateral submandibular glands (p max and Lem E 5 % values for bilateral submandibular glands. There were also significant differences in T max and Lem E 5 % values for bilateral parotid glands between mild oral problems and severe oral problems in patients with CRF (undergoing hemodialysis). In this study, prolonged T max and T min values, and decreased Lem E 5 % values for parotid glands and prolonged T min values for submandibular glands on salivary scintigraphy pointed out decreased parenchymatous and excretory function in patients with CRF undergoing hemodialysis.

Luca Levrini

2014-12-01

Full Text Available Rapid maxillary expansion (RME is a widely used practice in orthodontics. Scientific evidence shows that RME can be helpful in modifying the breathing pattern in mouth-breathing patients. In order to promote the restoration of physiological breathing we have developed a rehabilitation program associated with RME in children. The aim of the study was a literature review and a model of orofacial rehabilitation in children with obstructive sleep apnea undergoing treatment with rapid maxillary expansion. Muscular training (local exercises and general ones is the key factor of the program. It also includes hygienic and behavior instructions as well as other therapeutic procedures such as rhinosinusal washes, a postural re-education (Alexander technique and, if necessary, a pharmacological treatment aimed to improve nasal obstruction. The program should be customized for each patient. If RME is supported by an adequate functional rehabilitation, the possibility to change the breathing pattern is considerably amplified. Awareness, motivation and collaboration of the child and their parents, as well as the cooperation among specialists, such as orthodontist, speech therapist, pediatrician and otolaryngologist, are necessary conditions to achieve the goal.

Sterilization is most widely used fertility regulation method in Nepal. However, prevalence of uptake of female sterilization in central hilly region is less than the national average. The objective of the study was to explore the number and factors related to intention of married women to undergo female sterilization in rural Kathmandu which lies within central hilly region. This is a community based cross-sectional survey research conducted in rural area of Kathmandu valley. Two hundred and forty currently married women with at least one child of any age were interviewed using a structured pre-tested questionnaire. More than four-fifth of the respondents intended to undergo sterilization. Almost two-third of them wanted to limit their family size by taking this option. More than one-third of women not-intending to undergo sterilization feared weakness after sterilization. Age of the respondents, duration of marriage, and number of living children were significantly associated with intention to undergo sterilization. 15-24 years age group were six times more likely to have the intention for sterilization (OR 6.79, CI 2.28-20.19) compared to age 35 years and above group. Mothers with less than 3 living children are about three times more likely to have the intention to undergo sterilization (OR 2.87, CI 1.3-6.33) compared to women with more than 2 living children. Women married for 6 to 10 years were three times more likely to have the intention (OR 3.0, CI 1.09-8.27). However, gender of the living children was not associated with intention to undergo sterilization. There were significant numbers of women intending to undergo sterilization. Age of the mother, number of living children and the duration of marriage were found to be significantly influencing the intention to undergo sterilization. However, as intention refers to future plan, the respondents' intention may change over time. The national family planning program also needs to identify the key factors in

AIM: To investigate the effect of pain relief after infusion of ropivacaine at port sites at the end of surgery. METHODS: From October 2006 to September 2007, 72 patients undergoing laparoscopic cholecystectomy (LC) were randomized into two groups of 36 patients. One group received ropivacaine infusion at the port sites at the end of LC and the other received normal saline. A visual analog scale was used to assess postoperative pain when the patient awakened in the operating room, 6 and 24 h after surgery, and before discharge. The amount of analgesics use was also recorded. The demographics, laboratory data, hospital stay, and perioperative complications were compared between the two groups. RESULTS: There was no difference between the two groups preoperatively in terms of demographic and laboratory data. After surgery, similar operation time, blood loss, and no postoperative morbidity and mortality were observed in the two groups. However, a significantly lower pain score was observed in the patients undergoing LC with local anesthesia infusion at 1 h after LC and at discharge. Regarding analgesic use, the amount of meperidine used 1 h after LC and the total used during admission were lower in patients undergoing LC with local anesthesia infusion. This group also had a shorter hospital stay. CONCLUSION: Local anesthesia with ropivacaine at the port site in LC patients significantly decreased postoperative pain immediately. This explains the lower meperidine use and earlier discharge for these patients. PMID:19452582

To evaluate predictors of allogenic blood transfusion requirements in patients undergoing minimal invasive oesophagectomy at a tertiary high volume centre for oesophago-gastric surgery. Retrospective analysis of all patients undergoing minimal access oesophagectomy in our department between January 2010 and December 2011. Patients were divided into two groups depending on whether they required a blood transfusion at any time during their index admission. Factors that have been shown to influence perioperative blood transfusion requirements in major surgery were included in the analysis. Binary logistic regression analysis was performed to determine the impact of patient and perioperative characteristics on transfusion requirements during the index admission. A total of 80 patients underwent minimal access oesophagectomy, of which 61 patients had a laparoscopic assisted oesophagectomy and 19 patients had a minimal invasive oesophagectomy. Perioperative blood transfusion was required in 28 patients at any time during hospital admission. On binary logistic regression analysis, a lower preoperative haemoglobin concentration (p blood transfusion requirements. It has been reported that requirement for blood transfusion can affect long-term outcomes in oesophageal cancer resection. Two factors which could be addressed preoperatively; haemoglobin concentration and type of oesophageal resection, may be valuable in predicting blood transfusions in patients undergoing minimally invasive oesophagectomy. Our analysis revealed that preoperative haemoglobin concentration, occurrence of significant complications and type of minimal access oesophagectomy predicted blood transfusion requirements in the patient population examined.

Retrospective database analysis. To investigate incidence, comorbidities, and impact on health care resources of Clostridium difficile infection after lumbar spine surgery. C. difficile colitis is reportedly increasing in hospitalized patients and can have a negative impact on patient outcomes. No data exist on estimates of C. difficile infection rates and its consequences on patient outcomes and health care resources among patients undergoing lumbar spine surgery. The Nationwide Inpatient Sample was examined from 2002 to 2011. Patients were included for study based on International Classification of Diseases, Ninth Revision, Clinical Modification, procedural codes for lumbar spine surgery for degenerative diagnoses. Baseline patient characteristics were determined and multivariable analyses assessed factors associated with increased incidence of C. difficile and risk of mortality. The incidence of C. difficile infection in patients undergoing lumbar spine surgery is 0.11%. At baseline, patients infected with C. difficile were significantly older (65.4 yr vs. 58.9 yr, Pinfection. Small hospital size was associated with decreased odds (odds ratio [OR], 0.5; Pinfection. Uninsured (OR, 1.62; Pinfection. C. difficile increased hospital length of stay by 8 days (Pdifficile infection after lumbar spine surgery carries a 36.4-fold increase in mortality and costs approximately $10,658,646 per year to manage. These data suggest that great care should be taken to avoid C. difficile colitis in patients undergoing lumbar spine surgery because it is associated with longer hospital stays, greater overall costs, and increased inpatient mortality. 3.

International Nuclear Information System (INIS)

Ferreira, M. R.; Amado, A.; Jorge, M.; Grillo, I. M.

2011-01-01

Background: Stevens Johnson Syndrome and Erythema Multiforme are hypersensitivity skin reactions generally arising in the context of multiple causes. Radiation therapy is considered to be one of these causes, although most reports are hindered by concomitant medications. Aim: The aim of this paper was to present a case of Stevens Johnson Syndrome arising in a patient undergoing gynaecological brachytherapy with an unusual presentation. Case:We describe a case of a 56-year-old woman with endometrial cancer undergoing adjuvant gynaecological radiotherapy. While undergoing a gynaecological brachytherapy boost, she developed bilateral conjunctivitis that progressed to oral mucositis and pruritic erythema with sloughing of the skin on her arms and legs but not the torso or irradiated fields (namely the vaginal mucosa). Conclusion: This case illustrates the association of RT/SJS; however, it also raises the question of patients undergoing RT being more susceptible to SJS as opposed to a direct cause of the disease.

An innovative practice, therapeutic touch has been used for around ten years in the treatment of eating disorders. Delivered by nurse clinicians having received specific training, this approach is based on nursing diagnoses which identify the major symptoms of this pathology. The support is built around the body and its perceptions. Through the helping relationship, it mobilises the patient's resources to favour a relationship of trust, a letting-go, physical, psychological and emotional relaxation, and improves the therapeutic alliance.

Unconscious emotional reasoning and the therapeutic misconception.

Science.gov (United States)

Charuvastra, A; Marder, S R

2008-03-01

The "therapeutic misconception" describes a process whereby research volunteers misinterpret the intentions of researchers and the nature of clinical research. This misinterpretation leads research volunteers to falsely attribute a therapeutic potential to clinical research, and compromises informed decision making, therefore compromising the ethical integrity of a clinical experiment. We review recent evidence from the neurobiology of social cognition to provide a novel framework for thinking about the therapeutic misconception. We argue that the neurobiology of social cognition should be considered in any ethical analysis of how people make decisions about participating in clinical trials. The neurobiology of social cognition also suggests how the complicated dynamics of the doctor-patient relationship may unavoidably interfere with the process of obtaining informed consent. Following this argument we suggest new ways to prevent or at least mitigate the therapeutic misconception.

2013-02-01

Full Text Available Traumatic bile leaks often result in high morbidity and prolonged hospital stay that requires multimodality management. Data on endoscopic management of traumatic bile leaks are scarce. Our study objective was to evaluate the efficacy of the endoscopic management of a traumatic bile leak. We performed a retrospective case review of patients who were referred for endoscopic retrograde cholangiopancreatography (ERCP after traumatic bile duct injury secondary to blunt (motor vehicle accident or penetrating (gunshot trauma for management of bile leaks at our tertiary academic referral center. Fourteen patients underwent ERCP for the management of a traumatic bile leak over a 5-year period. The etiology included blunt trauma from motor vehicle accident in 8 patients, motorcycle accident in 3 patients and penetrating injury from a gunshot wound in 3 patients. Liver injuries were grade III in 1 patient, grade IV in 10 patients, and grade V in 3 patients. All patients were treated by biliary stent placement, and the outcome was successful in 14 of 14 cases (100%. The mean duration of follow-up was 85.6 days (range 54-175 days. There were no ERCP-related complications. In our case review, endoscopic management with endobiliary stent placement was found to be successful and resulted in resolution of the bile leak in all 14 patients. Based on our study results, ERCP should be considered as first-line therapy in the management of traumatic bile leaks.

The Japan Endoscopy Database (JED) Project was started to develop the world's largest endoscopic database, capture the actual performance of endoscopic practice, and standardize the terminology and fundamental items needed for a clinical and research registry. This paper presents a progress report on the first phase of this project undertaken at eight endoscopic centers in Japan. The list of data items to be collected was drafted by the MSED-J (Minimal Standard Endoscopic Database) subcommittee. These items were aggregated offline by integrating data from two endoscopic filing systems between July 2015 and December 2015. The study population included all patients who underwent esophagogastroduodenoscopy or colonoscopy at all eight centers, patients who underwent enteroscopy at five of the eight centers, and patients who underwent endoscopic retrograde cholangiopancreatography (ERCP) at four of the eight centers. Data collected in this phase included 61 070 endoscopic procedures, of which 40 475 were esophagogastroduodenoscopies, 215 were enteroscopies, 19 204 were colonoscopies, and 1176 were ERCPs. Frequencies of complications were 0.68% for esophagogastroduodenoscopy, 0% for enteroscopy, 0.43% for colonoscopy, and 13.34% for ERCP. In addition, we obtained various data including Helicobacter pylori infection status, past history of endoscopy in patients who underwent enteroscopy or colonoscopy, and degree of difficulty of ERCP, although the frequencies of reporting were sometimes low, with some items <20%. Results of the first phase suggest that the JED project can provide vast quantities of useful data about endoscopic procedures. © 2017 Japan Gastroenterological Endoscopy Society.

AIM: To assess the role of ultrasound (US), magnetic resonance cholangiopancreatography (MRCP) and liver function tests (LFTs) in the evaluation of selected patients presenting with late post-cholecystectomy syndrome (PCS) who were referred for endoscopic retrograde cholangiopancreatography (ERCP) MATERIALS AND METHODS: In a retrospective study a final group of 42 patients with PCS referred for diagnostic ERCP underwent MRCP and abdominal US. ERCP and MRCP images were assessed for bile duct diameters and the presence of strictures and stones. A common bile duct (CBD) diameter of <10 mm was considered normal, whereas ≥10 mm was considered abnormal on US. Findings were correlated to LFTs with contingency table results performed for single techniques and combination of methods. RESULTS: In total 14 stones and one stricture were seen. US had a high negative predictive value (86.4%). MRCP had a sensitivity of 100% and specificity of 88.0%. ERCP is the most accurate test but failed in 11 patients, five of whom had a stone. The accuracy of US and LFTs increases to 93.8% if test results agree in either negative or positive outcome. CONCLUSION: US and LFTs are first-line tests in PCS. If the CBD on US is ≥10 mm, but no cause is identified, MRCP should be performed. If US and LFTs are normal then MRCP is not necessary. The availability of LFTs raises the diagnostic value of imaging

The aim of this study was to evaluate the utility of an Australasian registry ('the Registry') for children undergoing radiation treatment (RT). Children under the age of 16years who received a course of radiation between January 1997 and December 2010 and were enrolled on the Registry form the subjects of this study. A total of 2232 courses of RT were delivered, predominantly with radical intent (87%). Registrations fluctuated over time, but around one-half of children diagnosed with cancer undergo a course of RT. The most prevalent age range at time of RT was 10–15years, and the most common diagnoses were central nervous system tumours (34%) and acute lymphoblastic leukaemia (20%). The Registry provides a reflection of the patterns of care of children undergoing RT in Australia and a mechanism for determining the resources necessary to manage children by RT (human, facilities and emerging technologies, such as proton therapy). It lacks the detail to provide information on radiotherapy quality and disease outcomes which should be the subject of separate audit studies. The utility of the Registry has been hampered by its voluntary nature and varying needs for consent. Completion of registry forms is a logical requirement for inclusion in the definition of a subspecialist in paediatric radiation oncology.

Objective: To compare the severity of carotid artery disease in diabetic and non-diabetic patients undergoing coronary artery bypass grafting. Methods: From January to June 2008, 379 patients undergoing elective coronary artery bypass surgery were preoperatively evaluated for the presence of carotid stenoses by duplex scanning. Patients were divided into two groups, Group I, 156 (41.2%) diabetic patients and Group II, 223 (58.8%) non-diabetic patients. Results: There were 314 (82.8%) males and 65 (17.2%) females with a mean age of 57.2+-9.1 years. In diabetic group there were 125 (80.1%) males and 31 (19.9%) females with a mean age of 56.3+-8.9 years. Left main stem stenosis was present in 59 (37.8%) diabetics and 45 (20.2%) non-diabetics (p 70% stenosis was present in 20 (5.3%) with 13 (8.3%) diabetics and 7 (3.1%) non-diabetics (p<0.025). Stenosis of 50-70% was observed in 30 (7.9%) of which 17 (10.9%) were diabetics and 13 (5.8%) were non-diabetics. Conclusion: Presence of diabetes mellitus is associated with diffuse coronary artery disease and significant carotid artery disease in patients undergoing coronary artery bypass grafting. (author)

To investigate the effects of different tilt angles of head-up tilt test (HUTT) and different responses to HUTT on the psychological fear in children undergoing the test. HUTT was performed on children with unexplained syncope or pre-syncope (107 cases: 52 males and 55 females), aged 5.5-17.8 years (mean 12.0±2.8 years). All subjects were randomly assigned to undergo HUTT at an angle of 60°, 70° or 80°; the negative cases underwent sublingual nitroglycerin-provocation HUTT at the same tilt angle. The Wong-Baker Faces Pain Rating Scale was used for self-assessment of psychological fear in subjects during HUTT at the end point of the test. The positive rate, hemodynamic changes and distribution of response types showed no significant differences between children at tilt angles of 60°, 70° and 80° (P>0.05). The greater the tilt angle, the higher the degree of psychological fear in children undergoing the test, but there were no significant differences between them (P>0.05). The degree of psychological fear in children who showed a positive response to HUTT (n=76) was significantly higher than that in children who showed a negative response (n=31) (Pfear in children undergoing the test, and the degree of psychological fear increases in children tested at tilt angles from 60° to 80°, but the differences have no statistical significance. A positive response to HUTT can significantly increase the psychological fear in children.

Diverticular disease of the colon is frequent in clinical practice, and a large number of patients each year undergo surgical procedures worldwide for their symptoms. Thus, there is a need for better knowledge of the basic pathophysiologic mechanisms of this disease entity. Because patients with colonic diverticular disease have been shown to display abnormalities of the enteric nervous system, we assessed the frequency of myenteric plexitis (i.e. the infiltration of myenteric ganglions by inflammatory cells) in patients undergoing surgery for this condition. We analyzed archival resection samples from the proximal resection margins of 165 patients undergoing left hemicolectomy (60 emergency and 105 elective surgeries) for colonic diverticulitis, by histology and immunochemistry. Overall, plexitis was present in almost 40% of patients. It was subdivided into an eosinophilic (48%) and a lymphocytic (52%) subtype. Plexitis was more frequent in younger patients; and it was more frequent in those undergoing emergency surgery (50%), compared to elective (28%) surgery (p = 0.007). All the severe cases of plexitis displayed the lymphocytic subtype. In conclusion, myenteric plexitis is frequent in patients with colonic diverticular disease needing surgery, and it might be implicated in the pathogenesis of the disease.

Because the islets of Langerhans are more prevalent in the body and tail of the pancreas, distal pancreatectomy (DP) is believed to increase the likelihood of developing new onset diabetes mellitus (NODM). To determine whether the development of postoperative diabetes was more prevalent in patients undergoing DP or Whipple procedure, 472 patients undergoing either a DP (n = 122) or Whipple (n = 350), regardless of underlying pathology, were analyzed at one month postoperatively. Insulin or oral hypoglycemic requirements were assessed and patients were stratified into preoperative diabetic status: NODM or preexisting diabetes. A retrospective chart review of the 472 patients between 1996 and 2014 showed that the total rate of NODM after Whipple procedure was 43 per cent, which was not different from patients undergoing DP (45%). The incidence of preoperative diabetes was 12 per cent in patients undergoing the Whipple procedure and 17 per cent in the DP cohort. Thus, the overall incidence of diabetes after Whipple procedure was 54 and 49 per cent in the DP group. The development of diabetes was unrelated to the type of resection performed. Age more than 65 and Caucasian ethnicity were associated with postoperative diabetes regardless of the type of resection performed.

Full Text Available Background: Primary hyperaparathyroidism (pHPT is often accompanied by underlying thyroid pathology that can confound preoperative parathyroid localization studies and complicate intra-operative decision making. The aim of this study was to examine the utility of preoperative thyroid ultrasonography (US in patients prior to undergoing parathyroidectomy for pHPT.Methods: An Institutional Review Board approved prospective study was undertaken from January 2005 through July 2008. All patients with pHPT meeting inclusion criteria (n=94 underwent preoperative thyroid ultrasound in addition to standard 99mTc-sestamibi scintigraphy for parathyroid localization. Demographics, operative management and final pathology were examined in all cases.Results: Fifty-four of the 94 patients (57% were noted to have a thyroid nodule on preoperative US, of which 30 (56% underwent further examination with fine needle aspiration biopsy. Alteration of the operative plan attributable to underlying thyroid pathology occurred in 16 patients (17%, with patients undergoing either total thyroidectomy (n=9 or thyroid lobectomy (n=7. Thyroid cancer was noted in 33% of patients undergoing thyroid resection, and 6% of all patients with HPT.Conclusions: The routine utilization of preoperative thyroid ultrasound in patients prior to undergoing parathyroid surgery for pHPT is indicated. The added information from this non-invasive modality facilitates timely management of co-incidental, and sometimes malignant, thyroid pathology.

Tranexamic acid reduces the risk of bleeding among patients undergoing cardiac surgery, but it is unclear whether this leads to improved outcomes. Furthermore, there are concerns that tranexamic acid may have prothrombotic and proconvulsant effects. In a trial with a 2-by-2 factorial design, we randomly assigned patients who were scheduled to undergo coronary-artery surgery and were at risk for perioperative complications to receive aspirin or placebo and tranexamic acid or placebo. The results of the tranexamic acid comparison are reported here. The primary outcome was a composite of death and thrombotic complications (nonfatal myocardial infarction, stroke, pulmonary embolism, renal failure, or bowel infarction) within 30 days after surgery. Of the 4662 patients who were enrolled and provided consent, 4631 underwent surgery and had available outcomes data; 2311 were assigned to the tranexamic acid group and 2320 to the placebo group. A primary outcome event occurred in 386 patients (16.7%) in the tranexamic acid group and in 420 patients (18.1%) in the placebo group (relative risk, 0.92; 95% confidence interval, 0.81 to 1.05; P=0.22). The total number of units of blood products that were transfused during hospitalization was 4331 in the tranexamic acid group and 7994 in the placebo group (Ptranexamic acid group and in 2.8% of the patients in the placebo group (P=0.001), and seizures occurred in 0.7% and 0.1%, respectively (P=0.002 by Fisher's exact test). Among patients undergoing coronary-artery surgery, tranexamic acid was associated with a lower risk of bleeding than was placebo, without a higher risk of death or thrombotic complications within 30 days after surgery. Tranexamic acid was associated with a higher risk of postoperative seizures.

Acute Organophosphate Poisonings: Therapeutic Dilemmas and New Potential Therapeutic Agents

It has been six decades since synthesis of organophosphates, but this chapter has not yet come to a closure. Toxic effects of organophosphates are well known and the current therapeutic scheme includes supportive therapy and antidotes. There is a dilemma on whether and when to apply gastric lavage and activated charcoal. According to Position Statement (by EAPCCT) it should be applied only if the patient presents within one hour of ingestion, with potentially lethal ingested dose. Atropine, a competitive antagonist of acetylcholine at m-receptors, which antagonizes bronchosecretion and bronchoconstriction, is the corner stone of acute organophosphate poisoning therapy. There were many attempts to find a more efficient drug, including glycopyrrolate which has been used even in clinical trials, but it still can not replace atropine. The only dilemma about atropine usage which still exists, concerns usage of high atropine dose and scheme of application. The most efficient atropinization is achieved with bolus doses of 1-2mg of atropine i.v push, with repeating the dose on each 5 minutes until signs of atropinization are registered. Diazepam, with its GABA stabilizing effect, reduces central nervous system damage and central respiratory weakness. Oximes reactivate phosphorylated acetylcholinesterase, which still has not gone ageing, reducing acetylcholine concentration and cholinergic crisis. These effects are clearly demonstrated in experimental conditions, but the clinical significance of oximes is still unclear and there are still those who question oxime therapy. For those who approve it, oxime dosage, duration of therapy, the choice of oxime for certain OP is still an open issue. We need new, more efficient antidotes, and those that are in use are only the small part of the therapy which could be used. Experimental studies show favorable therapeutic effect of many agents, but none of them has been introduced in standard treatment of OPI poisoning in the last 30

Objective: To detect the changes of serum NSE, SIL-2R and TNF levels in the 33 patients with lung cancer undergoing chemotherapy. Methods: Serum NSE, SIL-2R and TNF levels were determined with RIA and SIL-2R levels with ELISA in 33 lung cancer patients both before and after chemotherapy (n=28) as well as in 30 controls. Results: Before chemotherapy, serum NSE, SIL-2R and TNF levels in the patients were significantly higher than those in the controls (P<0.01). After chemotherapy, in 20 cases without recurrence at 6 months, the levels were much lower but still significantly higher than those in controls (P < 0.05 ). However, in the 8 patients with recurrence, the levels increased again to approaching those before chemotherapy. Conclusion: Serum levels of NSE, SIL-2R and TNF might be useful for diagnosis and predicting therapeutic effects after chemotherapy in patients with lung cancer. (authors)

The importance of Observational Therapeutics in the progress of medicine has been neglected in the current era of the hierarchal position imparted to Randomized Controlled Trials (RCTs) for new drug discovery and practice of evidence-based medicine. There is a need to reflect on the reason for many new drugs being withdrawn during post marketing surveillance. There are several examples in literature where drug-discovery has originated initially from keen clinical and / or laboratory observations. The roots of these discoveries have often been from observations made by practitioners of traditional medicine including Ayurveda. The present article draws attention to the scope and challenges for observational therapeutics. There is an urgent need for the meticulous planning for a systematic organization of developing observational therapeutics, with a full understanding of its strengths and limitations.

The aim of this study is to evaluate the organ doses of patients undergoing hepatic chemoembolization procedures performed in two hospitals in the city of Recife-Brazil. Forty eight patients undergoing fifty hepatic chemoembolization procedures were investigated. For the 20 cases with PA projection only, organ and tissue absorbed doses as well as radiation risks were calculated. For this purpose organs and tissues dose to KAP conversion coefficients were calculated using the mesh-based phantom series FASH and MASH coupled to the EGSnrc Monte Carlo code. Clinical, dosimetric and irradiations parameters were registered for all patients. The maximum organ doses found were 1.72 Gy, 0.65Gy, 0.56 Gy and 0.33 Gy for skin, kidneys, adrenals and liver, respectively. (authors)

Therapeutic Vaccination for HPV Induced Cervical Cancers

Directory of Open Access Journals (Sweden)

Joeli A. Brinkman

2007-01-01

Full Text Available Cervical Cancer is the second leading cause of cancer–related deaths in women worldwide and is associated with Human Papillomavirus (HPV infection, creating a unique opportunity to treat cervical cancer through anti-viral vaccination. Although a prophylactic vaccine may be available within a year, millions of women, already infected, will continue to suffer from HPV-related disease, emphasizing the need to develop therapeutic vaccination strategies. A majority of clinical trials examining therapeutic vaccination have shown limited efficacy due to examining patients with more advanced-stage cancer who tend to have decreased immune function. Current trends in clinical trials with therapeutic agents examine patients with pre-invasive lesions in order to prevent invasive cervical cancer. However, longer follow-up is necessary to correlate immune responses to lesion regression. Meanwhile, preclinical studies in this field include further exploration of peptide or protein vaccination, and the delivery of HPV antigens in DNA-based vaccines or in viral vectors. As long as pre-clinical studies continue to advance, the prospect of therapeutic vaccination to treat existing lesions seem good in the near future. Positive consequences of therapeutic vaccination would include less disfiguring treatment options and fewer instances of recurrent or progressive lesions leading to a reduction in cervical cancer incidence.

Statins and sartans can, in therapeutic doses, induce pleiotropic cardiovascular effects. Similar has recently been shown also for sub-therapeutic doses. We thus explored and compared the cardiovascular pleiotropic efficacy of sub-therapeutic vs. therapeutic doses. Wistar rats were randomly divided into 7 groups receiving fluvastatin, valsartan and their combination in sub-therapeutic and therapeutic doses, or saline. After 6weeks, the animals were euthanised, their hearts and thoracic aortas isolated, and blood samples taken. Endothelium-dependent relaxation of the thoracic aortae and ischaemic-reperfusion injury of the isolated hearts were assessed along with the related serum parameters and genes expression. Fluvastatin and valsartan alone or in combination were significantly more effective in sub-therapeutic than therapeutic doses. The sub-therapeutic combination greatly increased thoracic aorta endothelium-dependent relaxation and maximally protected the isolated hearts against ischaemia-reperfusion injury and was thus most effective. Beneficial effects were accompanied by increased levels of nitric oxide (NO) and decreased levels of asymmetric dimethylarginine (ADMA) in the serum (again prominently induced by the sub-therapeutic combination). Furthermore, nitric oxide synthase 3 (NOS3) and endothelin receptor type A (EDNRA) genes expression increased, but only in both combination groups and without significant differences between them. In the therapeutic dose groups, fluvastatin and valsartan decreased cholesterol values and systolic blood pressure. Sub-therapeutic doses of fluvastatin and valsartan are more effective in expressing cardiovascular pleiotropic effects than therapeutic doses of fluvastatin and/or valsartan. These results could be of significant clinical relevance. Copyright © 2017 Elsevier Inc. All rights reserved.

Avian Diagnostic and Therapeutic Antibodies

A number of infectious agents have the potential of causing significant clinical symptomology and even death, but dispite this, the number of incidence remain below the level that supports producing a vaccine. Therapeutic antibodies provide a viable treatment option for many of these diseases. We proposed that antibodies derived from West Nile Virus (WNV) immunized geese would be able to treat WNV infection in mammals and potential humans. We demonstrated that WNV specific goose antibodies are indeed successful in treating WNV infection both prophylactically and therapeutically in a golden hamster model. We demonstrated that the goose derived antibodies are non-reactogenic, i.e. do not cause an inflammatory response with multiple exposures in mammals. We also developed both a specific pathogen free facility to house the geese during the antibody production phase and a patent-pending purification process to purify the antibodies to greater than 99% purity. Therefore, the success of these study will allow a cost effective rapidly producible therapeutic toward clinical testing with the necessary infrastructure and processes developed and in place.

The study was aimed at determining the dynamics of the emotional state and factors influencing thereupon in patients presenting with atherosclerosis of lower limb arteries and undergoing surgical treatment. The study included a total of sixty-five 36-to-90-year-old patients (53 men and 12 women) subjected to examination twice - prior to surgery and before discharge by means of semi-structured interview, self-assessment scale of feeling and mood, methods "Integrative test of anxiety" and "Type of attitude towards the disease" (TOBOL), questionnaire for assessing health-related quality of life SF-36 and Krantz questionnaire in order to determine the position in the therapeutic process. After surgery (on postoperative day 7-10 of hospital stay) the patients demonstrated a decrease in the degree of anxiety and somatic complaints. Women (p=0.037), patients with the duration of the disease from 1 to 8 years (p=0.033), with signs of personality anxiety (p≤0.045), disadaptive variants of attitude to disease and treatment (p≤0.05), as well as clearly manifesting mistrust for medical recommendations (p=0.014) belong to a group of risk of emotional stress at the postoperative stage. Clinical and socio-demographic determinants are comparatively less important in formation of pronounced anxiety of postoperative period than the patient's personality.

Potential Therapeutic Effects of Psilocybin.

Johnson, Matthew W; Griffiths, Roland R

2017-07-01

Psilocybin and other 5-hydroxytryptamine 2A agonist classic psychedelics have been used for centuries as sacraments within indigenous cultures. In the mid-twentieth century they were a focus within psychiatry as both probes of brain function and experimental therapeutics. By the late 1960s and early 1970s these scientific inquires fell out of favor because classic psychedelics were being used outside of medical research and in association with the emerging counter culture. However, in the twenty-first century, scientific interest in classic psychedelics has returned and grown as a result of several promising studies, validating earlier research. Here, we review therapeutic research on psilocybin, the classic psychedelic that has been the focus of most recent research. For mood and anxiety disorders, three controlled trials have suggested that psilocybin may decrease symptoms of depression and anxiety in the context of cancer-related psychiatric distress for at least 6 months following a single acute administration. A small, open-label study in patients with treatment-resistant depression showed reductions in depression and anxiety symptoms 3 months after two acute doses. For addiction, small, open-label pilot studies have shown promising success rates for both tobacco and alcohol addiction. Safety data from these various trials, which involve careful screening, preparation, monitoring, and follow-up, indicate the absence of severe drug-related adverse reactions. Modest drug-related adverse effects at the time of medication administration are readily managed. US federal funding has yet to support therapeutic psilocybin research, although such support will be important to thoroughly investigate efficacy, safety, and therapeutic mechanisms.

Immunogenicity of therapeutic proteins lowers patient well-being and drastically increases therapeutic costs. Preventing immunogenicity is an important issue to consider when developing novel therapeutic proteins and applying them in the clinic. Animal models are increasingly used to study immunogenicity of therapeutic proteins. They are employed as predictive tools to assess different aspects of immunogenicity during drug development and have become vital in studying the mechanisms underlying immunogenicity of therapeutic proteins. However, the use of animal models needs critical evaluation. Because of species differences, predictive value of such models is limited, and mechanistic studies can be restricted. This review addresses the suitability of animal models for immunogenicity prediction and summarizes the insights in immunogenicity that they have given so far.

Advances in cancer therapy have improved the long term survival of young patients suffering from malignancies. However adverse effects of the treatment are sterlity and loss of gonadal function especially in females. Preservation of fertility in males by sperm freezing is more practical and already established. For young women undergoing cancer treatment , the availability of preserving the gonadal function and fertility has just begun.Today we can crypreserve the oocytes, the embryos or rhe ovarian tissue and those undergoing pelvic irradtion, laparascopic can be cnsidered. Because women with non-gynelical malagnencies seek advice from a general surgeon or a medical onconologist, increasing awawreness of physician and general public is recommended. (author)

This paper quantifies the extent of the radiation hazard to personnel from horses undergoing scintigraphy using technetium{sup 99m} methylene diphosphonate ({sup 99m}Tc{sup m}-MDP). From the data produced it is possible to derive safe working protocols which are comfortably within the legislated limits for whole body doses as set out in the Ionising Radiations Regulations 1985. Measurements were made of the surface and environmental activities which result from individuals undergoing scintigraphic evaluation and also from urine contaminated bedding. The use of both high and low activities in the assessment of the radiation hazard to personnel and owners is considered. (author).

Full Text Available Background and Objectives Chronic renal disease is a threatening condition for the health, economic, and social status of the affected person and his/her family. Patients undergoing hemodialysis encounter mental and health problems; the current study aimed at predicting resilience via social support and illness perceptions among patients undergoing hemodialysis. Methods The current descriptive-correlational study had a statistical population including 308 patients undergoing hemodialysis in Kerman, Iran, in 2017. Based on the Krejcie-Morgan table, the minimum required sample size was 169. The sample was selected using a convenience sampling method. Data collection tools were the Connor-Davidson resilience scale, the medical outcome study (MOS social support survey developed by Sherbourne and Stewart, and the brief illness perception questionnaire developed by Broadbent et al. Data were analyzed using a Pearson correlation coefficient and a stepwise regression analysis via SPSS version 19. Results Results indicated that resilience was significantly and positively related to social support (r = 0.318, P < 0.05 and illness perceptions (r = 0.165, P < 0.05. Among the subscales of social support, emotional support, tangible support, and social interaction could predict resilience, and among the subscales of illness perceptions, only cognitive representation could predict resilience. Conclusions The obtained results demonstrated that resilience was significantly and positively related to social support and illness perceptions. Additionally, the subscales of social support and illness perceptions could predict resilience among the patients undergoing hemodialysis.

Failure of cisplatin-based chemotherapy in advanced germ cell tumour (GCT) is associated with a poor outcome. High-dose chemotherapy and auto-SCT is one therapeutic option, although the long-term outcome after this procedure is unclear. We conducted a multicentre cohort study of consecutive patients undergoing a single auto-SCT for GCT between January 1986 and December 2004. Of 71 subjects, median follow-up is 10.1 years. OS at 5 years is 44.7% (95% confidence interval (CI) 32.9-56.5%) and EFS is 43.5% (95% CI 31.4-55.1%). There were seven (10%) treatment-related deaths within 100 days of auto-SCT. Three (4.2%) patients developed secondary malignancies. Of 33 relapses, 31 occurred within 2 years of auto-SCT. Two very late relapses were noted 13 and 11 years after auto-SCT. In multivariate analysis, favourable outcome was associated with IGCCC (International Germ Cell Consensus Classification) good prognosis disease at diagnosis, primary gonadal disease and response to salvage chemotherapy. We conclude that auto-SCT results in successful outcome for a relatively large subgroup of patients with high-risk GCT. Late relapses may occur, a finding not previously reported.

Marsden, J P; Meehan, R A; Calkins, M P

2001-01-01

Long-term care facilities are increasingly incorporating some sort of kitchen, often referred to as a therapeutic kitchen, for resident, staff, and family use through remodeling efforts or new construction. A study, consisting of five site visits and a questionnaire mailed to 631 facilities providing dementia care, was conducted to identify physical features that are typically included in therapeutic kitchen design and to explore how these features support daily use in relation to activities programming and food service systems. Findings indicate that universal design features should be incorporated to a greater extent and certain features are more common, reinforce homelike imagery, or enhance safety. Results also suggest that a higher number of residents participate in more recreational activities, such as baking, than they do in household chores, such as meal set-up, and therapeutic kitchens are not always linked to food service systems.

Early allograft dysfunction (EAD) is a serious complication of liver transplantation (LT) and is associated with graft failure, which can result in patient mortality. Due to the shortage of organs for retransplantation, only a small proportion of EAD patients undergo retransplantation. Thus, liver support is needed for most patients with EAD. We evaluated the effects of therapeutic plasma exchange (TPE) in EAD patients. EAD was defined as a sustained hyperbilirubinemia (≥10 mg/dL) within 30 days of LT without concurrent biliary complications. In a 13-year period, 107 EAD patients underwent TPE while 36 EAD patients did not. We investigated the laboratory and clinical outcomes of TPE and non-TPE groups. The TPE group showed 1-month and 1-year survival rates of 82.2% and 53.8%, respectively, whereas the non-TPE group showed 58.3% and 22.2%, respectively. In TPE group, statistically significant decreases (P higher INR on the day of EAD onset increased the risk. TPE effectively removed plasma bilirubin and improved coagulation function in EAD patients, with higher survival in the TPE group than in the non-TPE group. TPE may be an effective liver support for EAD patients. J. Clin. Apheresis 32:147-153, 2017. © 2016 Wiley Periodicals, Inc. © 2016 Wiley Periodicals, Inc.

Kennedy, C

2012-02-01

Thromboprophylaxis for women undergoing caesarean section (CS) was introduced in the hospital in 1995. This study audited the use of tinzaparin prophylaxis in a nested cohort of women who screened negative for diabetes mellitus at 28 weeks gestation. All the women had their weight measured and BMI calculated at the first antenatal visit. Of the 284 women, 68 (24%) had a CS and all received tinzaparin. Of the 68, however, 94% received a dose lower than recommended. Compliance with prophylaxis was complete but compliance with the recommended dosage was suboptimal, which may result in venous thromboembolism after CS despite thromboprophylaxis.

The radiation exposure dose must be optimised because the hazard resulting from an interventional radiology procedure is long term depending on the patient. The aim of this study was to measure the radiation doses received by the patients and medical staff during endoscopic retrograde cholangio-pancreatography (ERCP) procedures. Data were collected during 126 ERCP procedures, including the dose-area product (DAP), entrance dose (ED), effective dose (E), fluoroscopy time (T) and number of digital radiographs (F). The medical staff members each wore a personal thermoluminescence dosemeter to monitor exposure during ERCP procedures. The mean DAP, ED, E and T were 47.06 Gy cm 2 , 196.06 mGy, 8.93 mSv, 7.65 min and 9.21 images, respectively. The mean dose to the staff was 0.175 mSv and that to the assistant was 0.069 mSv. The dose to the medical staff was minimal when appropriate protective measures were used. The large variation in the patient doses must be further investigated. (authors)

To evaluate cholangiographic abnormalities resulting from extrahepatic portal venous obstruction (EHPVO) by sonography and endoscopic retrograde cholangiopancreaticography (ERCP). Material and Methods: Forty-three patients with an established diagnosis of EHPVO were subjected to duplex Doppler sonography and ERCP. Of these, 8 patients had obstructive jaundice. Results: Dilated common bile duct with pericholedochal varices showing a continuous type of flow pattern was seen in 5 EHPVO patients with obstructive jaundice. ERCP revealed cholangiographic abnormalities in 40 patients (93%). Extrahepatic bile ducts were involved in 100% of cases compared to intrahepatic bile ducts (57%). Abnormalities noted were contour irregularity with indentations, displacement and angulation, strictures and filling defects in the extrahepatic ductal system. Intrahepatic bile ducts showed dilatation with areas of narrowing and filling defects. Conclusion: Cholangiographic abnormalities are very common in patients with EHPVO, even without clinical manifestations of biliary disease. Extrahepatic bile ducts are far more often involved compared to intrahepatic bile ducts. Extrinsic compression with contour irregularity is the most common cholangiographic finding. Sonographic findings are not diagnostic. Dilated common bile duct with pericholedochal varices was seen in only 5 patients

Full Text Available Bronchobiliary Fistula (BBF is a rare condition that usually occurs after surgical treatments of pancreas, liver and biliary diseases. Clinical findings are bilioptysis, fever and dyspnea. In treating it, initially, drainage should be conducted using minimally invasive or endoscopic methods, such as endoscopic retrograde cholangiopancreatography (ERCP or percutaneous transhepatic cholangiography (PTK in cases where these methods failed. Next, treatment through performing surgical operations, like hepatectomy or pulmonary resection, should be carried out. In this work, the diagnostic and therapeutic phases of a female patient at the age of 40 who underwent a whipple procedure (pancreatoduodenectomy 10 years earlier because of pancreatic neuroendocrine tumor is presented. Their follow-ups exhibited multiple metastases in the liver, and for this reason, specific chemoembolization treatments were applied. After these treatments, bronchobiliary fistula was formed.

Full Text Available Psychological assessment has long been reported as a key component of clinical psychology. This paper examines the complexities surrounding the clinical significance of therapeutic approach to treatment planning. To achieve this objective, the paper searched and used the PsycINFO and PubMed databases and the reference sections of chapters and journal articles to analysed, 1 a strong basis for the usage of therapeutic approach to psychological assessment in treatment plans, 2 explained the conceptual meaning of clinical significant change in therapeutic assessment, 3 answered some of the questions regarding practicability and the clinical significance of therapeutic approach to treatment plans, particularly during or before treatment, 4 linked therapeutic assessment to change in clients’ clinical impression, functioning and therapeutic needs 5 analysed the empirically documenting clinically significant change in therapeutic assessment. Finally, the study suggested that though therapeutic assessment is not sufficient for the systematic study of psychotherapy outcome and process, it is still consistent with both the layman and professional expectations regarding treatment outcome and also provides a precise method for classifying clients as ‘changed’ or ‘unchanged’ on the basis of clinical significance criteria.

Nonthermal effects of therapeutic ultrasound: the frequency resonance hypothesis.

Johns, Lennart D

2002-07-01

To present the frequency resonance hypothesis, a possible mechanical mechanism by which treatment with non-thermal levels of ultrasound stimulates therapeutic effects. The review encompasses a 4-decade history but focuses on recent reports describing the effects of nonthermal therapeutic levels of ultrasound at the cellular and molecular levels. A search of MEDLINE from 1965 through 2000 using the terms ultrasound and therapeutic ultrasound. The literature provides a number of examples in which exposure of cells to therapeutic ultrasound under nonthermal conditions modified cellular functions. Nonthermal levels of ultrasound are reported to modulate membrane properties, alter cellular proliferation, and produce increases in proteins associated with inflammation and injury repair. Combined, these data suggest that nonthermal effects of therapeutic ultrasound can modify the inflammatory response. The concept of the absorption of ultrasonic energy by enzymatic proteins leading to changes in the enzymes activity is not novel. However, recent reports demonstrating that ultrasound affects enzyme activity and possibly gene regulation provide sufficient data to present a probable molecular mechanism of ultrasound's nonthermal therapeutic action. The frequency resonance hypothesis describes 2 possible biological mechanisms that may alter protein function as a result of the absorption of ultrasonic energy. First, absorption of mechanical energy by a protein may produce a transient conformational shift (modifying the 3-dimensional structure) and alter the protein's functional activity. Second, the resonance or shearing properties of the wave (or both) may dissociate a multimolecular complex, thereby disrupting the complex's function. This review focuses on recent studies that have reported cellular and molecular effects of therapeutic ultrasound and presents a mechanical mechanism that may lead to a better understanding of how the nonthermal effects of ultrasound may be

The intercultural and interracial therapeutic relationship: challenges and recommendations.

Qureshi, Adil; Collazos, Francisco

2011-01-01

Although research has demonstrated that mental health services function with patients from different cultural backgrounds, a variety of culture- and race-related factors can result in services being of lower quality than that which occurs when the clinician and patient are from the same culture. The provision of culturally competent care requires many institutional and organizational adaptations that lie beyond the control of most mental health professionals. The therapeutic relationship, however, remains a key factor of mental healthcare that can be attended to by individual therapists. The therapeutic relationship plays an important role in almost every therapeutic approach, and has been increasingly recognized as representing a means to the provision of quality intercultural and interracial treatment. At the same time, a host of cultural and racial factors relating to both the patient and clinician can compromise the development of the therapeutic relationship. This paper will explore some of the key issues that complicate therapeutic contact and communication, and will outline means by which to strengthen key components of the therapeutic relationship.

[Purpose] The intensity of therapeutic physical exercise is complex and sometimes controversial in patients with neural injuries. This review assessed whether therapeutic physical exercise is beneficial according to the intensity of the physical exercise. [Methods] The authors identified clinically or scientifically relevant articles from PubMed that met the inclusion criteria. [Results] Exercise training can improve body strength and lead to the physiological adaptation of skeletal muscles and the nervous system after neural injuries. Furthermore, neurophysiological and neuropathological studies show differences in the beneficial effects of forced therapeutic exercise in patients with severe or mild neural injuries. Forced exercise alters the distribution of muscle fiber types in patients with neural injuries. Based on several animal studies, forced exercise may promote functional recovery following cerebral ischemia via signaling molecules in ischemic brain regions. [Conclusions] This review describes several types of therapeutic forced exercise and the controversy regarding the therapeutic effects in experimental animals versus humans with neural injuries. This review also provides a therapeutic strategy for physical therapists that grades the intensity of forced exercise according to the level of neural injury.

Background Therapeutic phlebotomy is increasingly used in patients with transfusional siderosis to mitigate organ injury associated with iron overload (IO). Laboratory response parameters and therapy duration are not well characterized in such patients. Methods We retrospectively evaluated 99 consecutive patients undergoing therapeutic phlebotomy for either transfusional IO (TIO, n=88; 76% had undergone hematopoietic transplantation) or non-transfusional indications (hyperferritinemia or erythrocytosis) (n=11). CBC, serum ferritin (SF), transferrin saturation, and transaminases were measured serially. Phlebotomy goal was an SF< 300 mcg/L. Results Mean SF prior to phlebotomy among TIO and nontransfusional subjects was 3,093 and 396 mcg/L, respectively. Transfusion burden in the TIO group was 94 ± 108 (mean ± SD) RBC units; about half completed therapy with 24 ± 23 phlebotomies (range 1–103). One-third was lost to follow-up. Overall, 15% had mild adverse effects, including headache, nausea, and dizziness, mainly during first phlebotomy. Prior transfusion burden correlated poorly with initial ferritin and total number of phlebotomies to target (NPT) in the TIO group. However, NPT was strongly correlated with initial SF (R2=0.8; p<0.0001) in both TIO and nontransfusional groups. ALT decreased significantly with serial phlebotomy in all groups (mean initial and final values, 61 and 39 U/L; p = 0.03). Conclusions Initial SF but not transfusion burden predicted number of phlebotomies to target in patients with TIO. Despite good treatment tolerance, significant losses to follow-up were noted. Providing patients with an estimated phlebotomy number and follow-up duration, and thus a finite endpoint, may improve compliance. Hepatic function improved with iron off-loading. PMID:25209879

As the therapeutic options in the management of type 2 diabetes increase, there is an increase confusion among health care professionals, thus leading to the phenomenon of therapeutic inertia. This is the failure to escalate or de-escalate treatment when the clinical need for this is required. It has been studied extensively in various settings, however, it has never been reported in any studies focusing solely on primary care physicians with an interest in diabetes. This group is increasingly becoming the focus of managing complex diabetes care in the community, albeit with the support from specialists. In this retrospective audit, we assessed the prevalence of the phenomenon of therapeutic inertia amongst primary care physicians with an interest in diabetes in UK. We also assessed the predictive abilities of various patient level characteristics on therapeutic inertia amongst this group of clinicians. Out of the 240 patients reported on, therapeutic inertia was judged to have occurred in 53 (22.1%) of patients. The full model containing all the selected variables was not statistically significant, p=0.59. So the model was not able to distinguish between situations in which therapeutic inertia occurred and when it did not occur. None of the patient level characteristics on its own was predictive of therapeutic inertia. Therapeutic inertia was present only in about a fifth of patient patients with diabetes being managed by primary care physicians with an interest in diabetes.

Full Text Available The primary purpose of this study was to determine the oral manifestations of patients undergoing dialysis. Two subgroups of the population were studied: (1 Those who have been on dialysis for less than one year, (2 those who have been on dialysis for more than one year. Two dental indices–periodontal index and decayed, missing, filled index were used to identify periodontal status, dental canes activity. Data were compiled and analyzed by using the unpaired t-test. Results suggested that 100% (n = 26 of the patients undergoing dialysis presented with some form of periodontal disease (mean value = 2.24, standard deviation = 1.33. Majority of the patients displayed either established periodontal disease (57.6% or the beginning of periodontal disease (38 4%. Approximately, 70% of the patients had high decayed, missing, filled index (mean value = 6.19, standard deviation = 6.40. Findings led to the conclusion that patients on dialysis need comprehensive professional oral care and self-care instructions. The source of infection in oral cavity can cause variety of systemic diseases, causing morbidity and mortality in these immune-suppressed patients.
