RESUMO
BACKGROUND: Minimal hepatic encephalopathy (HE) and HE grade 1 (HE1) according to the West Haven criteria have recently been grouped as one entity named-covert HE- (CHE). Data regarding the impact of CHE on health-related quality of life (HRQoL) and sleep quality are controversial. AIM: First, to determine whether CHE affects HRQoL and sleep quality of cirrhotic patients and second, whether minimal HE (MHE) and HE1 affect HRQoL and sleep quality to a comparable extent. METHODS: A total of 145 consecutive cirrhotic patients were enrolled. HE1 was diagnosed clinically according to the West Haven criteria. Critical flicker frequency and the Psychometric Hepatic Encephalopathy Score were used to detect MHE. Chronic Liver Disease Questionnaire (CLDQ) was used to assess HRQoL and Pittsburgh Sleep Quality Index (PSQI) was applied to assess sleep quality. RESULTS: Covert HE was detected in 59 (40.7%) patients (MHE: n = 40; HE1: n = 19). Multivariate analysis identified CHE (P < 0.001) and female gender (P = 0.006) as independent predictors of reduced HRQoL (CLDQ total score). CHE (P = 0.021), low haemoglobin (P = 0.024) and female gender (P = 0.003) were identified as independent predictors of poor sleep quality (PSQI total score). Results of CLDQ and PSQI were comparable in patients with HE1 and MHE (CLDQ: 4.6 ± 0.9 vs 4.5 ± 1.2, P = 0.907; PSQI: 11.3 ± 3.8 vs 9.9 ± 5.0, P = 0.3). CONCLUSION: Covert HE was associated with impaired HRQoL and sleep quality. MHE and HE1 affected both outcomes to a comparable extent supporting the use of CHE as a clinically useful term for patients with both entities of HE in clinical practice.

Nonerosive reflux disease (NERD) is commonly diagnosed in patients with symptoms of reflux. The aim of the present study was to determine whether high-definition endoscopy (HD) plus equipped with the iScan function or chromoendoscopy with Lugol's solution might permit the differentiation of NERD patients from those without reflux symptoms, proven by targeted biopsies of endoscopic lesions. A total of 100 patients without regular intake of proton pump inhibitors and with a normal conventional upper endoscopy were prospectively divided into NERD patients and controls. A second upper endoscopy was performed using HD+ with additional iScan function and then Lugol's solution was applied. Biopsy specimens were taken from the gastroesophageal junction in all patients. A total of 65 patients with reflux symptoms and 27 controls were included. HD(+) endoscopy with iScan revealed subtle mucosal breaks in 52 patients; the subsequent biopsies confirmed esophagitis in all cases. After Lugol's solution, 58 patients showed mucosal breaks. Sensitivity for the iScan procedure was 82.5%, whereas that for Lugol's solution was 92.06%. Excellent positive predictive values of 100% and 98.3%, respectively, were noted. The present study suggests that the majority of patients with NERD and typical symptoms of reflux disease can be identified by iScan or Lugol's chromoendoscopy as minimal erosive reï¬ux disease (ERD) patients.

BACKGROUND: Liver cirrhosis develops as a terminal complication of chronic liver disease. The clinical course is determined by the underlying etiology and the accompanying risk factors, which are influenced by the geographic and cultural background. METHODS: A total of 236 patients (159 men, 77 women, median age 57 [22-81] years) were included for retrospective analysis between July 2012 and February 2014 using standardized questionnaires during an outpatient visit at a hepatology clinic. RESULTS: The most common etiologies of liver cirrhosis were related to alcohol consumption (52â%), chronic hepatitis C (28â%) or hepatitis B (14â%) infection and NASH (nonalcoholic steatohepatitis, 6â%). At the time of presentation 55â% patients had compensated cirrhosis corresponding to Child-Turcotte-Pugh (CTP) stage A, while 45â% were in a decompensated stage (30â% CTP B and 15â% CTP C). Subgroups were analyzed for the incidence of complications and the emergence of infections. Most frequently esophageal varices (60â%) and ascites (49â%) were observed, followed by pleural effusion (14â%), hepatic encephalopathy (25â%) or hepatorenal syndrome (18â%). 16â% of patients exhibited infection based on clinical criteria. An infective agent was isolated in 38â% of all cases with infection and of those 50â% were gram positive bacteria. In multivariate analysis only the presence of ascites was an independent risk factor for infection. CONCLUSION: Despite improved medical therapies for viral hepatitis, these were the most frequent causes of liver cirrhosis, closely followed by alcoholic cirrhosis. The observed complications included bacterial infection and complication related to portal hypertension.

Upon returning from holidays, a 55-year-old patient presenting with melena and haemorrhagic shock was admitted to a University hospital after receiving first emergency medical care in a German InterCity train. In an interdisciplinary effort, haemodynamics were stabilised and the airway and respiratory function were secured. Under emergency care conditions the patient then underwent an emergency upper GI endoscopy where a spurting arterial upper gastrointestinal bleeding (Forrest 1a) was found. While the bleeding could not be controlled with endoscopic techniques, definitive haemostasis was achieved with a surgical laparotomy. While not commonly established for patients with severe GI bleeding, by spontaneous implementation of an interdisciplinary trauma room approach following established trauma algorithms the team was able to achieve stabilisation of vital functions and final control of bleeding in this highly unstable patient. Although the majority of upper gastrointestinal bleedings spontaneously cease, emergency care algorithms should be developed and implemented for patients with severe gastrointestinal bleedings in shock. Following the case vignette, we discuss a potential approach and develop an exemplary protocol for shock room management in this patient subgroup.

IgG4-related disease has gained increased attention worldwide. While the initial focus was on autoimmune pancreatitis which was first described in Asian populations and turned out to be of relevance in Western populations too, the scope has recently broadened towards a notion of a multi-systemic disease with very diverse manifestations such as autoimmune pancreatitis, IgG4-related sclerosing cholangitis (IgG4-SC), retroperitoneal fibrosis and tubulointerstitial nephritis. IgG4-SC (also known as IgG4-associated cholangitis, IAC) represents a rare but clinically challenging differential diagnosis in patients with obstructive jaundice and proximal extra- or intrahepatic biliary strictures which can be mistaken for cholangiocarcinoma (CC). We present the case of a 79-year-old male patient who presented with obstructive jaundice and biliary strictures at the hepatic duct bifurcation without any evidence for autoimmune pancreatitis and without elevation of serum IgG4-concentrations who underwent hemihepatectomy for suspected CC. However, on histological examination of the resection specimen CC could not be confirmed. It was only after several episodes of obstructive jaundice had reoccurred that the diagnosis of IgG4-SC could be established by reexamination of the surgical specimen which showed extensive infiltration with IgG4-positive plasma cells. Appropriate medical treatment with steroids and azathioprine led to complete remission of the disease. Early recognition of IgG4-SC can save patients from potential harmful and unnecessary surgical interventions. Here we describe the clinical features of this rare case of IgG4-SC with extensive liver tissue infiltration with IgG4-positive cells but without elevated serum IgG4 concentration or evidence of autoimmune pancreatitis. We describe diagnostic criteria for IgG4-SC and review recent insights in pathophysiology and treatment options.

OBJECTIVE: Colonoscopy is the accepted gold standard for screening of neoplastic colorectal lesions, but the substantial miss rate remains a challenge. Computed virtual chromoendoscopy with the Fujinon intelligent colour enhancement (FICE) system is a new dyeless imaging technique that might allow higher rates of adenoma detection. METHODS: This is a prospective randomised five tertiary care centre trial of colonoscopy in the FICE mode versus standard colonoscopy with targeted indigocarmine chromoscopy (control group) in consecutive patients attending for routine colonoscopy. Histopathology of detected lesions was confirmed by evaluation of endoscopic resection or biopsy specimens. RESULTS: 871 patients were enrolled, and 764 patients (344 female, mean age 64 years) were subjected to final analysis (368 in the FICE group, 396 in the control group). In total, 236 adenomas (mean of 0.64 per case) were detected in the FICE group and 271 adenomas (mean of 0.68 per case) in the control group (p = 0.92). There was no statistically significant difference in the percentage of patients with >or=1 adenoma between the control group (35.4%) and the FICE group (35.6%) (p = 1.0). For the differential diagnosis of adenomas and non-neoplastic polyps, the sensitivity of FICE (92.7%) was comparable with that of indigocarmine (90.4%) (p = 0.44). CONCLUSIONS: At colonoscopy, adenoma detection rates are not improved by virtual chromoendoscopy with the FICE system compared with white light endoscopy with targeted indigocarmine spraying. However, FICE can effectively substitute for chromoscopy concerning the differentiation of neoplastic and non-neoplastic lesions.

BACKGROUND AND STUDY AIMS: For surveillance of Barrett's esophagus random stepwise four-quadrant biopsy (4QB) is recommended for detecting macroscopically occult neoplasias. Thorough performance of the systematic protocol is commonly hampered by poor visibility due to oozing from biopsy sites. Topical application of dilute epinephrine may prevent bleeding by vasoconstriction of superficial microvessels and might therefore enable "dry biopsy" sampling. The aim of this study was to examine the safety and efficacy of spraying dilute epinephrine for optimal 4QB mapping of Barrett's esophagus. PATIENTS AND METHODS: In this prospective, double-blind trial 40 patients with known long segment Barrett's esophagus were randomly allocated to undergo spraying with either dilute epinephrine (1 : 20 000) (epinephrine group; n = 20) or saline (control group; n = 20) before 4QB sampling. During endoscopies patients received continuous monitoring of vital parameters. Endoscopists blinded to randomization assessed visibility scores during biopsy sampling. Additionally, electronically stored images of the Barrett's esophagus segment after 4QB sampling were evaluated by blinded assessors. RESULTS: The mean length of Barrett's segments was 5.5 +/- 1.8 cm and the mean number of 4QBs was 12.5 +/- 3.6 with no statistically significant differences between control and epinephrine groups. Epinephrine spraying did not affect patients' vital parameters. Visualization ratings by endoscopists on site and by the assessors of the stored images were significantly better in the epinephrine compared with the control group (P < 0.05). Moreover, epinephrine spraying reduced the time for 4QB sampling (P = 0.015) and the mean number of saline flushes needed to maintain visibility (P = 0.0003). CONCLUSIONS: The novel "dry biopsy" technique with spraying of dilute epinephrine is safe, and facilitates thorough performance of systematic 4QB mapping of Barrett's esophagus by improvement of visibility.

A 31-year-old patient presented with chronic cough and thoracic pain. A pulmonary mass was seen on chest x-ray, and pulmonary segmental resection was done. Histopathologically, a pulmonary abscess cavity due to actinomycosis was found. Three months later, recurrence of actinomycosis at the thoracic wall was observed. Antibiotic therapy with penicillin was administered. Five months later, with the patient receiving continued antibiotic therapy, a thoracic wall abscess and fistula was diagnosed. Four weeks after abscess drainage and repeat intravenous antibiotic therapy, the patient was symptom-free and had remained symptom-free at 10 months of follow-up.

Gastroparesis is a common but challenging disorder which can be idiopathic or induced by a variety of underlying diseases, most frequently by diabetes, or post-surgical conditions of the upper abdomen. Clinicians must also consider rare causes of gastric motor dysfunction, such as collagen vascular disorders and paraneoplastic syndromes. Here we present the case of a patient with severe gastroparesis, who was admitted to our hospital for vomiting and weight loss of 25 kg within four months. Endoscopy showed a dilated fluid-filled stomach without peristalsis but no obstruction. High titres of anti-Hu antibodies were detected in patient's serum, supporting the diagnosis of severe paraneoplastic gastroparesis with chronic intestinal pseudo-obstruction. Fine-needle aspiration of suspicious mediastinal lymph nodes guided by endoscopic ultrasound revealed lymphatic metastases of a small-cell lung carcinoma. Jejunal tube feeding and chemotherapy with carboplatin and etoposide were initiated. Paraneoplastic gastrointestinal dysmotility is rare, however, clinicians should consider this differential diagnosis in otherwise unexplained gastrointestinal motor dysfunction. The pathophysiology of paraneoplastic gastroparesis, the diagnostic relevance of anti-Hu antibodies as well as therapeutic options are discussed.

BACKGROUND AND STUDY AIMS: Computed virtual chromoendoscopy (CVC) is a new imaging technique that enhances mucosal surface contrast and highlights the vascular pattern without the need for dye-spraying as in conventional chromoendoscopy. The aim of this prospective randomized pilot study with a crossover design was to compare CVC with conventional chromoendoscopy with acetic acid (CAA) for the detection of high grade intraepithelial neoplasia (HGIN) or early cancer in patients with Barrett's esophagus. PATIENTS AND METHODS: 57 patients with Barrett's esophagus (mean length 3.8 cm) and a history of HGIN/early cancer or suspected HGIN/early cancer were randomly allocated to undergo either CAA or CVC. All patients were re-examined with the alternative procedure at 4 - 6 weeks after the initial endoscopy. The two procedures were performed by five endoscopists, who were blinded to the findings of the other examination. At each examination, targeted biopsies were taken from all detected lesions, followed by random four-quadrant biopsies. RESULTS: In 24/57 patients, 30 lesions with HGIN/early cancer were detected. The sensitivity of targeted biopsies for HGIN/early cancer on a 'per lesion' basis was 87 % (26/30) for both CAA and CVC. The positive predictive value was 39 % (26/66) for CAA and 37 % (26/70) for CVC. In the 'per patient' analysis, sensitivity was 83 % (20/24) and 92 % (22/24) for CAA and CVC, respectively ( P = 0.617). Stepwise random four-quadrant biopsies identified only one patient with HGIN/early cancer that was missed by both, CAA and CVC. CONCLUSIONS: Computed virtual chromoendoscopy is a helpful adjunct for surveillance of Barrett's esophagus and appears to be as accurate as conventional chromoendoscopy in the detection of HGIN/early cancer.
