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 i Scan 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 i Scan 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 i Scan 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 i Scan 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 i Scan or Lugol's chromoendoscopy as minimal erosive reflux disease ( ERD) patients.

Stenotic lesions of the supra-aortic vessels have been reported in 2-6% of patients presenting with corresponding symptoms. In the past, these lesions have been treated with open surgical techniques. More recently, endovascular treatment approaches have been proposed for occlusive lesions in the innominate (IA) or common carotid (CCA) arteries. Retrograde stenting of IA and CCA lesions using flow reversal has been described in a retrospective case series; however, a modification of their technique is proposed. Case Presentation: The patient is a 68-year-old male with symptoms of right upper extremity claudication. CT angiogram revealed critical stenosis of the innominate artery and high-grade stenosis of the right subclavian artery. The patient consented to retrograde stenting of the innominate stenosis with neuroprotection using flow reversal or transcarotid revascularization (TCAR) in reverse. Surgical cut-down was performed of the carotid bifurcation, and a U-stitch was placed on the anterior wall of the distal common carotid artery. Flow reversal was achieved by connecting the arterial sheath to the venous sheath. The innominate lesion was crossed, primarily stented with a VBX stent, and post-dilated with a non-compliant balloon. Just prior to crossing the lesion and primary stent placement, the vessel loop around the common carotid and internal carotid arteries were pulled up to ensure neuroprotection while the stent was expanded. This was continued for two minutes before restoring antegrade flow first in the external carotid and then in the internal carotid artery. There were no adverse events. At one month follow-up, the patient reported no right arm claudication symptoms. TCAR for the proximal lesion as described in other case series may not adequately attain flow based neuroprotection. Under that circumstance, the arterial sheath is acting as a conduit to deliver the stent. Risk of embolization to the brain may not be mitigated when the proximal lesion is stented and antegrade flow restored.

Purpose: Traditional treatment of axillary-subclavian venous thrombosis is resource intensive due to the need for advanced nursing care and increased utilization of intensive care units for thrombolysis procedures. We recently encountered this in the management of 2 patients with effort-induced upper extremity venous thrombosis following COVID-19 infection and offer a treatment paradigm for consideration., Case Reports: A 30-year-old presented with 2 weeks of left upper extremity symptoms following COVID-19 infection. Duplex ultrasound demonstrated axillary-subclavian venous thrombosis and venogram confirmed total occlusion of the axillary and subclavian veins with profuse collaterals around the occlusion. Suction thrombectomy was performed successfully and veins remained patent at 6 month follow up. The patient declined first rib resection and stopped lifting weights. A 16-year-old presented with 4 days of right arm symptoms 1 month after testing positive for COVID-19. Duplex ultrasound revealed acute axillary and subclavian vein thrombosis and she underwent successful thrombectomy followed by balloon angioplasty with improvement in symptoms., Conclusion: The pandemic has strained health care resources such that the treatment of non-life-threatening conditions must be triaged to conserve resources. While axillary-subclavian venous occlusion is usually not life-threatening, timely treatment leads to decreased morbidity and better outcomes. Percutaneous aspiration and thrombectomy without adjunctive thrombolysis may be of benefit in reducing healthcare resource utilization while still achieving good outcomes during the COVID pandemic and beyond.

Objectives: PEPDar compared the tolerability and safety of ritonavir-boosted darunavir (DRV/r)-based post-exposure prophylaxis (PEP) with the tolerability and safety of standard of care (SOC). The primary endpoint was the early discontinuation rate among the per-protocol population., Methods: PEPDar was an open-label, randomized, multicentre, prospective, noninferiority safety study. Subjects were stratified by type of event (occupational vs. nonoccupational, i.e. sexual) and were randomized to receive DRV/r plus two nucleoside reverse transcriptase inhibitors (NRTIs) or SOC PEP. Twenty-two private or university HIV clinics in Germany participated. Subjects were ≥ 18 years old and had documented or potential HIV exposure and indication for HIV PEP. They initiated PEP not later than 72 h after the event and were HIV negative., Results: A total of 324 subjects were screened, the per-protocol population was 305, and 273 subjects completed the study. One hundred and fifty-five subjects received DRV/r-based PEP and 150 subjects received ritonavir-boosted lopinavir (LPV/r)-based PEP for 28-30 days; 298 subjects also received tenofovir/emtricitabine. The early discontinuation rate in the DRV/r arm was 6.5% compared with 10.0% in the SOC arm (P = 0.243). Adverse drug reactions (ADRs) were reported in 68% of DRV/r subjects and 75% of SOC subjects (P = 0.169). Fewer DRV/r subjects (16.1%) had at least one grade 2 or 3 ADR compared with SOC subjects (29.3%) (P = 0.006). All grades of diarrhoea, nausea, and sleep disorders were significantly less frequent with DRV/r, while headache was significantly more frequent. No HIV seroconversion was reported during follow-up., Conclusions: Noninferiority of DRV/r to SOC was demonstrated. DRV/r should be included as a standard component of recommended regimens in PEP guidelines., (© 2016 British HIV Association.)

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 (52 %), chronic hepatitis C (28 %) or hepatitis B (14 %) infection and NASH (nonalcoholic steatohepatitis, 6 %). At the time of presentation 55 % patients had compensated cirrhosis corresponding to Child-Turcotte-Pugh (CTP) stage A, while 45 % were in a decompensated stage (30 % CTP B and 15 % CTP C). Subgroups were analyzed for the incidence of complications and the emergence of infections. Most frequently esophageal varices (60 %) and ascites (49 %) were observed, followed by pleural effusion (14 %), hepatic encephalopathy (25 %) or hepatorenal syndrome (18 %). 16 % of patients exhibited infection based on clinical criteria. An infective agent was isolated in 38 % of all cases with infection and of those 50 % 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., (© Georg Thieme Verlag KG Stuttgart · New York.)

Therapeutic agents to inhibit tumour necrosis factor alpha (TNF-α) have dramatically improved the treatment options for patients with autoimmune diseases. Common side effects include an increased susceptibility towards infection. Hepatic side effects are less frequently observed. Elevated liver function tests, hyperbilirubinaemia reactivation of chronic viral hepatitis or even acute liver failure have been described. Some cases have exhibited an autoimmune phenotype with the emergence of autoantibodies and characteristic histological lesions. We report on three patients who received anti-TNF therapy for psoriasis and presented with elevated liver function tests in the further course. Histological and serum analysis revealed an autoimmune phenotype of liver injury. In light of the growing use of anti-TNF therapies, drug-induced liver injury (DILI) with an autoimmune phenotype is an important side effect. Since the pathophysiological mechanisms related to the autoimmune phenotype of liver injury during TNF-inhibition are not well understood, the cases detailed herein should help treating physicians to improve their understanding of the situation., (© Georg Thieme Verlag KG Stuttgart · New York.)

Disclosure is a prerequisite to receive disease-specific social support. However, in the case of a stigmatised disease, it can also lead to discrimination. We aimed to assess disclosure rates of HIV patients and the reactions they encountered in comparison to patients with chronic viral hepatitis or diabetes mellitus and patients' general perception of disease-specific discrimination. We constructed a self-report questionnaire, anonymously assessing the size of the social environment, the persons who had been informed, and the experienced reactions as perceived by the disclosing patients, to be rated on 1-4 point Likert scales. In addition, patients were asked whether they perceive general discrimination in Germany. One hundred and seventy-one patients were asked to participate. Five rejected, thus questionnaires from 83 patients with HIV, 42 patients with chronic viral hepatitis B (n = 9) or C (n = 33), and 41 patients with insulin-dependent diabetes mellitus (type I n = 14, type II n = 27) were analysed. Whereas the size of the social environment did not differ, HIV-infected patients were least likely to disclose their disease (60.7%, SD ± 31.9) to their social environment as compared to patients with chronic viral hepatitis (84.2 ± 23.3%, p<0.0001), or diabetes mellitus (94.4 ± 10.3%, p<0.0001), respectively. Within the HIV patient group, the mean disclosure rate was highest to partners (90.9%), followed by the public environment (65.2%), friends (59.4%) and family members (43.8%). HIV patients experienced supportive reactions after 79.3 ± 26.4% of disclosures, which was the case in 91.4 ± 19.6% and 75.7 ± 36.1% of patients with hepatitis or diabetes mellitus, respectively. 69.5% of HIV patients stated to perceive general discrimination in Germany. We conclude that HIV patients had experienced supportive reactions after the majority of disclosures, but the low rate points out that their information strategy had been very selective. Societal discrimination of HIV patients is still an issue and needs to be further addressed.

Background: Discussion of the volume-outcome relationship in pancreatic surgery has gained increasing interest. Currently, no data describe the situation in Germany. Pursuant to a recent legislative reform, a threshold of 10 operations per year was introduced for pancreatic surgery in 2006. This study describes the situation in Germany and the effect of the legislative reform between 2006 and 2009., Methods: In 2007 and 2010, anonymous questionnaires were sent to leading surgeons in the German Society of General and Gastrointestinal Surgery asking for the numbers of pancreatic operations, methods of operation, and mortality for the years 2006, 2008, and 2009. Volume categories were defined by dividing hospitals into quartiles according to their annual volume of operations., Results: The return rate was about 48%. In the years 2006, 2008, and 2009, overall mortality in all hospitals was 2.85%, 3.98%, and 2.58%. High volume was defined as ≥ 32 pancreatic operations (2006) and ≥ 34 pancreatic operations (2008, 2009). Although mortality decreased with increasing volume, mortality between each volume category was not statistically different in any year. In the years 2006, 2008, and 2009, the number of operations increased in university hospitals (38.4%, 51.2%, and 50.4%, P < .001) and decreased in teaching hospitals (51.8%, 41.3%, and 41.2%, P < .001). The number of hospitals that did not perform pancreatic operations increased from 15.6% to 32.5% and 31% (P < .001)., Conclusion: In pancreatic surgery, a centralization effect occurred after a legislative reform in Germany. Overall mortality after pancreatic resection in German hospitals is good. Although mortality decreases with greater volume, there were no differences compared to other volume categories. Also, low-volume hospitals can produce good results; however, the difference in quality is considerable among these institutions. Our data suggest that the German threshold agreement in pancreatic surgery might have a positive effect with regard to reproducible quality and outcome., (Copyright © 2012 Mosby, Inc.

A 35-year-old Kenian lady with advanced immunodeficiency due to HIV infection started on an antiretroviral therapy. Five months later, a severe colitis was diagnosed, however, no causal pathogen could be found. In order to avoid imminent perforation, a hemicolectomy became necessary, and immediately the symptoms and inflammation markers normalized rapidly. M. tuberculosis could be proven in culture in a draining abdominal lymph node. We assume that the severe inflammation was caused by an immune restoration inflammatory syndrome (IRIS). Essentials in diagnosis, pathogenesis and therapy of IRIS are discussed., (© Georg Thieme Verlag KG Stuttgart · New York.)

Esophageal involvement in the context of opportunistic infections in human immunodeficiency virus (HIV) positive patients is a frequent phenomenon. However, worldwide esophageal achalasia has been described only twice in HIV-infected patients.We report the case of a 44-year-old Caucasian patient with HIV and Hepatitis C virus (HIV/HCV) coinfection who, within 2.5 years, displayed a progressive symptomatology with dysphagia, retrosternal pain, regurgitation as well as a considerable loss of weight before achalasia was finally diagnosed. Treatment was performed primarily surgically by means of laparoscopic Heller myotomy with an anterior 180° semifundoplication according to Dor.Histopathology of the specimens taken from the lower esophageal sphincter high-pressure zone proved alterations with abundant connective tissue and only scarce parts of the smooth muscular system without inflammatory infiltrations. In addition, the ganglia cells of the myenteric plexus as well as the interstitial cells of Cajal were significantly reduced. Interestingly, specific gene sequences of the hepatitis C virus could be detected in the esophageal tissue specimen. In contrast, analysis of specific HIV-gene sequences in the same tissue revealed a negative result.The possible but previously unknown relationship between esophageal achalasia and coinfection with HIV and HCV, also described as neurotropic viruses, will be discussed.
