RESUMEN
The efficacy and safety of retreatment with varenicline in smokers attempting to quit were evaluated in this randomized, double-blind, placebo-controlled, multicenter trial (Australia, Belgium, Canada, the Czech Republic, France, Germany, the United Kingdom, and the United States). Participants were generally healthy adult smokers (≥ 10 cigarettes/day) with ≥ 1 prior quit attempt (≥ 2 weeks) using varenicline and no quit attempts in ≤ 3 months; they were randomly assigned (1:1) to 12 weeks' varenicline (n = 251) or placebo (n = 247) treatment, with individual counseling, plus 40 weeks' nontreatment follow-up. The primary efficacy end point was the carbon monoxide-confirmed (≤ 10 ppm) continuous abstinence rate for weeks 9-12, which was 45.0% (varenicline; n = 249) vs. 11.8% (placebo; n = 245; odds ratio: 7.08; 95% confidence interval: 4.34, 11.55; P < 0.0001). Common varenicline group adverse events were nausea, abnormal dreams, and headache, with no reported suicidal behavior. Varenicline is efficacious and well tolerated in smokers who have previously taken it. Abstinence rates are comparable with rates reported for varenicline-naive smokers.

AIMS: To evaluate the efficacy and tolerability of flexible-dose fesoterodine in subjects with overactive bladder (OAB) who were dissatisfied with previous tolterodine treatment. METHODS: This was a 12-week, open-label, flexible-dose study of adults with OAB (> or = 8 micturitions and > or = 3 urgency episodes per 24 h) who had been treated with tolterodine (immediate- or extended-release) for OAB within 2 years of screening and reported dissatisfaction with tolterodine treatment. Subjects received fesoterodine 4 mg once daily for 4 weeks; thereafter, daily dosage was maintained at 4 mg or increased to 8 mg based on the subject's and physician's subjective assessment of efficacy and tolerability. Subjects completed 5-day diaries, the Patient Perception of Bladder Condition (PPBC) and the Overactive Bladder Questionnaire (OAB-q) at baseline and week 12 and rated treatment satisfaction at week 12 using the Treatment Satisfaction Question (TSQ). Safety and tolerability were assessed. RESULTS: Among 516 subjects treated, approximately 50% opted for dose escalation to 8 mg at week 4. Significant improvements from baseline to week 12 were observed in micturitions, urgency urinary incontinence episodes, micturition-related urgency episodes and severe micturition-related urgency episodes per 24 h (all p < 0.0001). Approximately 80% of subjects who responded to the TSQ at week 12 reported satisfaction with treatment; 38% reported being very satisfied. Using the PPBC, 83% of subjects reported improvement at week 12 with 59% reporting improvement > or = 2 points. Significant improvements from baseline (p < 0.0001) exceeding the minimally important difference (10 points) were observed in OAB-q Symptom Bother and Health-Related Quality of Life (HRQL) scales and all four HRQL domains. Dry mouth (23%) and constipation (5%) were the most common adverse events; no safety issues were identified. CONCLUSION: Flexible-dose fesoterodine significantly improved OAB symptoms, HRQL, and rates of treatment satisfaction and was well tolerated in subjects with OAB who were dissatisfied with prior tolterodine therapy.

Erectile dysfunction (ED) negatively impacts self-esteem and relationship satisfaction. The Self-Esteem and Relationship (SEAR) questionnaire is a validated, ED-specific, patient-reported instrument that specifically addresses self-esteem and relationship issues within the context of ED. Effective ED treatment with sildenafil in a double-blind, placebo-controlled clinical trial conducted in Brazil, Mexico, Australia and Japan showed pooled cross-cultural improvements in self-esteem, confidence and relationship satisfaction. This report focuses on the results from the subgroup of men from nine Mexican centers who participated in the multinational study. A total of 95 men aged >or=18 years with clinically diagnosed ED and currently in a stable relationship were randomized to placebo (n=47) or sildenafil (n=48). The SEAR results for Mexican men showed that sildenafil treatment led to significant improvements in self-esteem, confidence and relationship satisfaction. These data support an earlier study showing that Latin American men taking sildenafil have similar safety and efficacy profiles compared to non-Latin counterparts.

AIMS: To evaluate once-daily 100-mg sildenafil for the treatment of erectile dysfunction (ED) in men with ED and lower urinary tract symptoms (LUTS) associated with benign prostatic hyperplasia (BPH). METHODS: This was a 12-week, randomised, double-blind, placebo-controlled (DBPC) trial, with an 8-week open-label (OL) extension, in men > or = 45 years of age who scored < or = 25 on the erectile function (EF) domain of the International Index of Erectile Function (IIEF) and > or = 12 on the International Prostate Symptom Score. RESULTS: At DBPC end of treatment (EOT), the sildenafil group (n = 189, vs. placebo, n = 180) had improved EF (IIEF), improved emotional well-being [Self-Esteem And Relationship questionnaire (SEAR)], and greater treatment satisfaction (Erectile Dysfunction Inventory of Treatment Satisfaction) (p < 0.0001). At OL EOT, IIEF and SEAR scores improved slightly in the group previously randomised to sildenafil (n = 168), but much more in the group previously randomised to placebo (N = 155), such that total improvement over the 20-week trial was comparable between the groups. Erections at baseline were hard enough for penetration on approximately half of occasions and lasted long enough for successful intercourse on less than one quarter of occasions, increasing at sildenafil DBPC and OL EOT to approximately 90% (penetration) and 80% (intercourse success) vs. 61% (penetration) and 39% (intercourse success) for DBPC placebo. At sildenafil DBPC and OL EOT, > or = 90% of men were taking sildenafil 100 mg. Sildenafil was generally well tolerated. CONCLUSIONS: In this trial of men with ED and BPH-associated LUTS, sildenafil treatment for ED was efficacious, effective and generally well tolerated.

We investigated the effect of early sildenafil dose optimization and personalized instructions on sexual intercourse success in 1109 men beginning sildenafil therapy for erectile dysfunction. In phase 1 (4 weeks), patients followed the instructions contained in the sildenafil (50 mg) sample pack and had 1.4 sexual intercourse attempts per week with 82% success. Patients (17%) had a second intercourse attempt (80% successful): 58% occurred within 4 h, 20% within 5-8 h, and 22% within 9-24 h of the first attempt. In phase 2 (4 weeks), sildenafil was adjusted as needed (53% to 100 mg, and 2% to 25 mg), and investigators provided personalized instructions to facilitate patient success. Sexual intercourse attempts increased to 1.7 per week, with 91% success, and 18% were followed by a second attempt, of which 91% were successful. Most patients requested the 100-mg dose, which helped improve sexual intercourse frequency, flexibility and success.

Erectile dysfunction (ED) is commonly associated with depressed mood and diminished quality of life (QoL), but few studies have investigated the causal associations involved. Therefore, we evaluated the correlation between several measures of mood, QoL, and sexual function in a retrospective analysis of a sample of depressed men (n=152), with ED enrolled in a clinical trial of sildenafil citrate (VIAGRA). Strong correlations were observed at baseline among measures of erectile function (EF), mood, and overall QoL. Significant treatment effects were observed on all three domains, with significant interactions between changes in mood and QoL. Based on multiple regression and path analysis, a model was developed in which EF changes were associated with improved mood and quality of sexual life, which resulted in improved partner satisfaction, family life, and overall life satisfaction. These data suggest that QoL changes associated with ED therapy may be mediated by changes in sexual function, mood, and family relationships.

OBJECTIVES: To determine the minimal time to successful intercourse after taking sildenafil citrate for erectile dysfunction (ED). METHODS: Male patients with ED (mean age 60 years; mean ED duration 7.0 years) who were successfully treated with sildenafil (100 mg) for 2 months or longer were randomized to sildenafil (n = 115) or placebo (n = 113) for 4 weeks of double-blind treatment. Using a stopwatch, patients recorded the time needed to obtain an erection hard enough for sexual intercourse after taking the study drug at least 2 hours after eating. RESULTS: Within 14 and 20 minutes of sildenafil dosing, 35% and 51% of sildenafil-treated patients, respectively, versus 22% and 30% of placebo-treated patients, respectively, had an erection that led to successful intercourse (P <0.05 for both). The median time to erection leading to successful intercourse after sildenafil dosing was 36 minutes compared with 141 minutes for placebo. CONCLUSIONS: In this study, slightly more than one half of a population of prior sildenafil responders achieved an erection that led to successful sexual intercourse within 20 minutes of sildenafil administration, suggesting that the onset of action of sildenafil can be less than 30 minutes in men with ED.

The voltage-sensing domains of voltage-gated potassium channels Kv2.1 (drk1) contain four transmembrane segments in each subunit, termed S1 to S4. While S4 is known as the voltage sensor, the carboxyl terminus of S3 (S3C) bears a gradually broader interest concerning the site for gating modifier toxins like hanatoxin and thus the secondary structure arrangement as well as its surrounding environment. To further examine the putative three-dimensional (3-D) structure of S3C and to illustrate the residues required for hanatoxin binding (which may, in turn, show the influence on the S4 in terms of changes in channel gating), molecular simulations and dockings were performed. These were based on the solution structure of hanatoxin and the structural information from lysine-scanning results for S3C fragment. Our data suggest that several basic and acidic residues of hanatoxin are electrostatically and stereochemically mapped onto their partner residues on S3C helix, whereas some aromatic or hydrophobic residues located on the same helical fragment interact with the hydrophobic patch of the toxin upon binding. Therefore, a slight distortion of the S3C helix, in a direction toward the N-terminus of S4, may exist. Such conformational change of S3C upon toxin binding is presented as a possible explanation for the observed shift in hanatoxin binding-induced gating.

BACKGROUND AND STUDY AIMS: Conventional endoscopic ultrasonography (EUS) is a valuable modality for staging the depth of invasion of colorectal cancer. However, there are difficulties with this technique in reaching as far as the cecal area, traversing tight strictures, and obtaining clear images of smaller lesions. Due to these factors, mis-staging often occurs. The literature shows that the miniprobe is superior to EUS, because of its easy manipulation and better diagnostic accuracy. We therefore conducted a prospective study using a balloon-sheathed miniprobe for colorectal cancer staging. PATIENTS AND METHODS: Eighty-six patients underwent preoperative staging using a miniprobe combined with an outer balloon sheath. Six patients were excluded from lymph-node examination due to local tumor resection. Acoustic coupling was achieved with or without water immersion. The results were compared with the histopathological findings in the resected specimens. RESULTS: The balloon-sheathed miniprobe had an overall accuracy rate of 85 % for T staging, with 100 % in T1; 78 % in T2; 90 % in T3; and 40 % in T4. Lymph-node metastasis was correctly diagnosed in 73 % of cases, with sensitivity and specificity rates of 74 % and 71 %, respectively. It was not possible to obtain clear cross-sectional images using the miniprobe in three patients. CONCLUSIONS: The balloon-sheathed miniprobe is a good alternative for evaluating colorectal tumor lesions, since it can usually obtain cross-sectional images even in markedly stenosed lesions, and the examination can be performed easily with endoscopy, with or without water-infusion techniques. One major limitation with the probe is the difficulty in evaluating deeper structures, such as lymph-node groups and contiguous organ involvement.

BACKGROUND: Intraductal ultrasound (IDUS) as an adjunct to ERCP for detection of extrahepatic bile duct stones is technically easy, accurate, and safe. This prospective study evaluated IDUS with an "over-the-wire" catheter US probe as an adjunct to ERCP. METHODS: Sixty-five patients, highly suspected to have choledocholithiasis, underwent IDUS during ERCP. The IDUS probe was inserted by means of the duodenoscope into the bile duct without performing a sphincterotomy. All stones identified by IDUS or retrograde cholangiography were removed with either a basket or retrieval balloon after endoscopic sphincterotomy. RESULTS: The final diagnosis was choledocholithiasis in 59 patients. Bile duct diameter ranged from 0.6 to 2.3 cm and stone size from 2 mm to 2 cm. IDUS successfully identified all stones in these patients. IDUS resulted in 2 false-positive diagnoses in the remaining 6 patients without stones (overall accuracy 97%, sensitivity 100%, specificity 67%). Cholangiography detected stones in 55 of the patients with stones (accuracy 94%, sensitivity 93%, specificity 100%). CONCLUSION: IDUS, a safe, technically easy procedure, is highly accurate in the detection of extrahepatic bile duct stones regardless of the diameter of the bile ducts. The "over-the-wire" technique preserves access to the cannulated duct. IDUS is an excellent adjunct to ERCP for the diagnosis of choledocholithiasis. IDUS differentiates stones from air bubbles and prevents unnecessary sphincterotomy.

PURPOSE: The purpose of this retrospective study was to compare the sensitivity of endoscopic sonography (EUS), transabdominal sonography (US), and CT in the detection of, local staging of, and prediction of vascular involvement by or distant metastasis from periampullary tumors. METHODS: Seventy-four consecutive patients with presumed periampullary tumors were evaluated by EUS, US, and CT during a 3.25-year period. The local staging accuracy of the modalities was assessed in the 36 patients with solid tumors who underwent surgery. The sensitivity of the modalities in predicting vascular involvement and distant metastasis was assessed in the 56 patients with carcinomas. RESULTS: EUS was the most sensitive modality in the detection (EUS, 97%; US, 24%; and CT, 39%; p < 0.001 for EUS versus US or CT) and T classification (EUS, 72%; US, 11%; CT, 22%; p < 0.001 for EUS versus US or CT) of periampullary tumors. EUS also had better sensitivity than US in detecting lymph node metastasis from periampullary cancers (EUS, 47%; US, 7%; and CT, 33%; p = 0.02 for EUS versus US; p = 0.7 for EUS versus CT). The accuracy of EUS in determining the T classification (without stent, 81%; with stent, 65%) and N classification (without stent, 80%; with stent, 70%) tended to decrease in the presence of an endobiliary stent, but the differences were not significant. EUS was the most sensitive modality in demonstrating vascular involvement (EUS, 100%; US, 0%; and CT, 33%; p = 0.002 for EUS versus US; p = 0.03 for EUS versus CT) but was not significantly different in detecting distant metastasis (EUS, 11%; US, 44%; and CT, 44%). CONCLUSIONS: EUS is superior to US and CT in the local assessment of periampullary tumors. The staging accuracy of EUS is minimally but not significantly affected by the presence of an endobiliary stent.

BACKGROUND/AIMS: To compare the accuracy between EUS (endoscopic ultrasound), ERCP (endoscopic retrograde cholangiopancreatography), CT (computed tomography), and transabdominal US (ultrasound) in the detection and staging of primary ampullary tumors. We will also try to discuss the influence of endobiliary stent on EUS in staging ampullary tumors. METHODOLOGY: Twenty-one patients with ampullary tumors were evaluated by EUS, ERCP, CT, and US before operation. The accuracy was assessed with TNM staging and compared with the surgical-pathological findings. RESULTS: EUS was superior to CT and US in detecting ampullary tumors, but EUS and ERCP are of similar sensitivity (EUS 95%, ERCP 95%, CT 19%, US 5%). EUS was superior to CT and US in T staging (EUS 75%, CT 5%, US 0%) and detecting lymph node metastasis (EUS 50%, CT 33%, US 0%) of ampullary tumors. The accuracy of EUS in T and N staging of ampullary tumors tended to be decreased in the presence of endobiliary stent (stenting: T 71%, N 75%; nonstenting T 83%, N 100%), but there was no statistical significance. CONCLUSIONS: EUS was superior to CT and US in assessing primary ampullary tumors, but it was not significantly superior to ERCP in detecting ampullary tumors. The presence of endobiliary stent may decrease the accuracy of EUS in staging ampullary tumors.

BACKGROUND/AIMS: This study is conducted to evaluate the feasibility of percutaneous transhepatic gallbladder drainage prior to laparoscopic cholecystectomy for the treatment of gallbladder empyema. We also determine the sonographic findings, causative organism, clinical signs and symptoms, laboratory data, associated underlying medical disorders and the complications related to both cholecystostomy and laparoscopic cholecystectomy. METHODOLOGY: One hundred and forty-five cases of gallbladder empyema were included in this study which was composed of 80 males and 65 females, aged 22-94 years with a mean age of 71-years. All patients underwent percutaneous transhepatic gallbladder drainage under ultrasound and fluoroscopic guidance, and laparoscopic cholecystectomy was carried out thereafter. We analyzed the clinical presentations (signs, symptoms, laboratory and ultrasonographic findings, concomitant medical disorders), causative organisms and the complications related to percutaneous cholecystostomy and laparoscopic cholecystectomy. RESULTS: Percutaneous transhepatic gallbladder drainage was performed successfully in all patients within 48 hours after clinical diagnosis of acute cholecystitis. Complications related to percutaneous transhepatic gallbladder drainage were bile leakage after tract dilatation noted in 2 patients (1.4%), and 20 (14%) patients had pain at the puncture site which radiated to the right shoulder during the procedure, but resolved spontaneously within an hour later. On admission, 102 (70%) patients presented as right upper quadrant pain, 39 (27%) as epigastric pain, 90 (62%) as fever, 108 (74%) patients had leukocytosis, and 33 (22.7%) patients were septic. AST and ALT were elevated in 57% and 51% of patients, respectively. Alkaline phosphatase was elevated in 56% of patients, and 34% of those patients had combined common bile duct stones. Gallbladder stones were documented in 135 (93%) patients, while the remaining 10 (7%) cases were acalculous. Five (3.4%) patients had combined gallbladder adenocarcinoma, 7 (4.8%) had liver abscess, while 13 (9%) had biliary pancreatitis. The ultrasonographic findings included gallbladder distension (93%), wall thickening (90%), pericholecystic fluid accumulation (15%), intraluminal sludge or stone (93%) and intraluminal air (13.9%). Bile culture were positive in 83% of the cases and showed gram-negative bacteria in 75%, gram-positive in 30%, anaerobes in 7%, while no growth in the remaining 17% of the cases. The common pathogens were Escherichia coli (57%), Enterococcus (27%), Klebsiella pneumonia (18%), Morganella morganii (7.6%), Pseudomonas aeruginosa (4.1%) and Salmonella (0.7%). The total postoperative complication rate was 17%, which included wound infection, bleeding, subhepatic abscess, cystic duct stump leak, common bile duct injury and pneumonia. Postoperative mortality was 2.6%. Conversion rate to open cholecystectomy was 27%. Clinical conditions improved within 48 hours after cholecystostomy in 93% of patients. Time interval between cholecystostomy and elective cholecystectomy was 2-21 days with a mean of 4 days. Total hospital stay was 5-38 days (mean: 11 days). CONCLUSIONS: Percutaneous transhepatic gallbladder drainage is a safe and effective procedure for the initial management of gallbladder empyema. We highly recommend this preoperative drainage procedure in patient with sepsis, and for those high-risk patients such as old age and with underlying medical illnesses. This procedure can stabilized the patient so that an appropriate therapeutic planning can be achieved.

BACKGROUND/AIMS: Clinical staging of gastric carcinoma is important in designing the strategy of treatment. Early gastric carcinomas can be treated by minimally invasive therapy, whereas advanced gastric carcinomas should be treated by surgery with or without combined chemotherapy. This study was undertaken to evaluate the accuracy and limitations of video type endoscopic ultrasound in preoperative staging of gastric cancer and assessing lymph node metastasis. METHODOLOGY: Seventy-four patients with gastric carcinoma were preoperatively staged using video-endoscopic ultrasonography, performed by the same gastroenterologist. RESULTS: Sixty-three out of the 74 (85%) patients were correctly staged by endoscopic ultrasonography. The diagnostic accuracy rate was 100% for T1, 74% for T2, 87% for T3, and 86% for T4. Overstaging occurred in 11% due to peritumoral inflammation. Understaging occurred in 4% due to microinvasion of carcinomatous tissue or deeper organ invasion. The diagnosis of lymph node metastasis was confirmed in 72% of cases. Sensitivity and specificity was 74% and 86%, respectively. CONCLUSIONS: Endoscopic ultrasonography has a high accuracy rate in staging gastric carcinoma but still has its limitations in evaluating regional lymph node metastasis, despite using a new generation video-endoscopic ultrasonography.

A 67 year-old man was admitted to the Tainan Municipal Hospital due to a protruding mass, usually noted during defecation. Digital examination revealed a single, smooth, large mass over the rectum, occupying almost the entire lumen. Colonoscopy, barium enema, and computed tomography (CT) demonstrated a submucosal tumor of the rectum. Endoscopic ultrasound (EUS) study showed that the tumor originated from the muscle layer. Based on the size, margin and echogenicity of the mass, a malignant neoplasm, probably leiomyosarcoma, was diagnosed. Post-operative histologic examination confirmed that the resected tumor was leiomyosarcoma. Existing ancillary procedures like colonoscopy, abdominal CT, magnetic resonance image (MRI), and barium enema are neither reliable nor accurate in locating which layer the lesion originates. Colonoscopic biopsy is disappointing since submucosal tumor is usually inaccessible. EUS study can provide us with a more distinct image with regards to tumor origin, size, margin and echogenicity. This report emphasizes the important role of EUS in the pre-operative diagnosis of submucosal tumors of the rectum. Furthermore, this tool can aid the surgeons whether wide excision or an abdomino-perineal resection should be performed.

BACKGROUND/AIMS: To assess the accuracy of a new generation endoscopic ultrasonography (EUS)(GF-M200) in pre-operative staging of recto-sigmoid colon carcinoma invasion and lymph node metastasis. METHODOLOGY: Seventy-three patients with biopsy proven colon cancer were included in this study. These comprised 60 patients with rectal carcinoma and 13 patients with sigmoid carcinoma. All patients were pre-operatively examined by EUS. Pathological findings of the depth of tumor invasion and presence of lymph node metastasis were correlated with EUS. RESULTS: EUS has an overall accuracy rate of 89% in staging of recto-sigmoid cancer. The diagnostic accuracy rate was 83% for T1, 83% for T2, 93% for T3, and 71% for T4. Understaging and overstaging occurred in 6% and 6%, respectively. In determining lymph node metastasis, the overall accuracy rate was 77%, with a sensitivity and specificity rate of 77% and 76%, respectively. CONCLUSIONS: EUS is a valuable staging modality in the staging of the depth of tumor invasion, not only for rectal carcinoma but also for tumors located at the sigmoid colon.

One hundred fifteen 2-year-old toddlers, one of the parents of each toddler, and the corresponding grandmother of each toddler were studied to determine the influence of the grandmother and the parent on the toddler's behavior. Findings indicated that the grandmother's parenting skills have an effect on the grandchild's anger via two pathways. More specifically, the grandmother's child-rearing techniques are mediated by the parent's personality traits, which, in turn, are associated with the parent's child-rearing practices and, ultimately, the grandchild's anger. The second pathway through which the grandmother's child-rearing is related to the grandchild's behavior involves the parent's imitation of the grandmother's parenting skills, which, in turn, are correlated with the toddler's behavior.

Intramural duodenal hematoma is rarely seen in adults and may occur as an iatrogenic complication of endoscopic injection for peptic ulcer treatment. In the appropriate clinical setting, the diagnosis is easy with its ultrasonography and computed tomography characteristic findings. In one of our patients, UGI study revealed duodenal obstruction, bowel related lesion in sonography and hyperdense mass lesion in computed tomography. Clinical presentation of severe vomiting and epigastralgia were noted. Laparoscopy confirmed the location of the hematoma and subsequent evacuation was performed. The symptoms were relieved after the operation and a follow-up sonography demonstrated the regression of the duodenal hematoma.

The intercorrelations among parents' drug use, personality, and parent-child relations and the child's anxious/regressive and reflective behaviors were investigated in a sample of 2-year-olds (N = 115). The results indicate that maternal child-rearing practices mediate the effect of maternal personality attributes on the child's intrapsychic functioning. The father's drug use had a direct influence on the child's reflective behavior. Generally, the mother's drug use, personality, and child-rearing practices were more important than the father's attributes. However, the father's drug use had a strong impact on the child when it interacted with the mother's drug use. Parental differences and implications for prevention are discussed.
