Student ultrasound education - current views and controversies.

As an extension of the clinical examination and as a diagnostic and problem-solving tool, ultrasound has become an established technique for clinicians. A prerequisite for high-quality clinical ultrasound practice is adequate student ultrasound training. In light of the considerable heterogeneity of ultrasound curricula in medical studies worldwide, this review presents basic principles of modern medical student ultrasound education and advocates for the establishment of an ultrasound core curriculum embedded both horizontally and vertically in medical studies.

[Early detection of pancreatic cancer - The role of endoscopic and transabdominal ultrasound]. / Frühdiagnose des Pankreaskarzinoms ­ Die Rolle von Endosonografie und Sonografie.

Pancreatic neoplasms are less common tumors and have a poor prognosis when advanced. Early diagnosis would be beneficial for survival, but screening of the whole population cannot be justified with a satisfying benefit-effort correlation. Subgroups of patients with a higher than average risk are those with germ-like mutations, familial cancers risks, and mucinous cystadenomas that would benefit from surveillance programs. Other risk groups, like patients with pancreatitis, new onset diabetes, and heavy smokers, should be considered as well. Transabdominal ultrasonography is of great advantage as a first-line imaging method because of its easy access. The accuracy for adenocarcinoma diagnosis is nearly 90% while using CEUS. Endosonography is of extraordinary importance in the diagnostic approach of pancreatic tumors because of high sensitivity and specificity while using advanced imaging techniques like CEUS, elastography, and fine needle biopsy. Screening by means of EUS is also possible in high-risk situations, and a favourable cost-benefit ratio must be shown by future data.

[Leading symptoms in proctological diseases and general measures]. / Leitsymptome bei proktologischen Erkrankungen und allgemeine Massnahmen.

Leading symptoms in proctological diseases and general measures Abstract. In addition to a general anamnesis, proctological diseases are characterised by five specific leading symptoms that determine the diagnostic procedure. In addition to general measures such as lifestyle and basic therapies, easy-to-use tips with no relevant side effects are explained.

[Internal hemorrhoidal disease and non-surgical therapy]. / Das innere Hämorrhoidalleiden und die nicht operative Therapie.

Internal hemorrhoidal disease and non-surgical therapy Abstract. Haemorrhoids are a physiological part of the sphincter muscle which, under non-physiological conditions such as abdominal pressure, becomes enlarged and develops symptoms such as bleeding. The therapy consists of reducing the enlarged plexus. In addition to lifestyle adaptations, semi-invasive methods such as coagulation, rubber band ligations and, in more severe stages, surgical procedures such as the classic established methods (Milligan-Morgan, Ferguson, in selected cases Longo) can be considered.

[Sexually transmitted anorectal infections]. / Sexuell übertragbare anorektale Infektionen.

Sexually transmitted anorectal infections Abstract. In recent years, the incidence of sexually transmitted infections in Switzerland has increased significantly for various reasons. They often manifest with anorectal symptoms, and may present as localized lesions, proctitis, or enteritis. To avoid misdiagnosis and stop transmissions to their sexual partners, testing for sexually transmitted diseases is indicated in most individuals with anorectal symptoms. This article provides an overview of the diagnosis and treatment of sexually transmitted anorectal infections.

The Contribution of the Left Phrenic Nerve to Innervation of the Esophagogastric Junction.

The contribution of the left phrenic nerve to innervation of the esophagogastric junction. The esophagogastric junction is part of the barrier preventing gastroesophageal reflux. We have investigated the contribution of the phrenic nerves to innervation of the esophagogastric junction in humans and piglets by dissecting 30 embalmed human specimens and 14 piglets. Samples were microdissected and nerves were stained and examined by light and electron microscopy. In 76.6% of the human specimens, the left phrenic nerve participated in the innervation of the esophagogastric junction by forming a neural network together with the celiac plexus (46.6%) or by sending off a distinct phrenic branch, which joined the anterior vagal trunk (20%). Distinct left phrenic branches were always accompanied by small branches of the left inferior phrenic artery. In 10% there were indirect connections with a distinct phrenic nerve branch joining the celiac ganglion, from which celiac plexus branches to the esophagogastric junction emerged. Morphological examination of phrenic branches revealed strong similarities to autonomic celiac plexus branches. There was no contribution of the left phrenic nerve or accompanying arteries from the caudal phrenic artery in any of the piglets. The right phrenic nerve made no contribution in any of the human or piglet samples. We conclude that the left phrenic nerve in humans contributes to the innervation of the esophagogastric junction by providing ancillary autonomic nerve fibers. Experimental studies of the innervation in pigs should consider that neither of the phrenic nerves was found to contribute. Clin. Anat. 33:265-274, 2020. © 2019 Wiley Periodicals, Inc.

Association of part-time clinical work with well-being and mental health in General Internal Medicine: A survey among Swiss hospitalists.

INTRODUCTION: Burnout and low job satisfaction are increasing among the General Internal Medicine (GIM) workforce. Whether part-time compared to full-time clinical employment is associated with better wellbeing, job satisfaction and health among hospitalists remains unclear. MATERIALS AND METHODS: We conducted an anonymized cross-sectional survey among board-certified general internists (i.e. hospitalists) from GIM departments in 14 Swiss hospitals. Part-time clinical work was defined as employment of <100% as a clinician. The primary outcome was well-being, as measured by the extended Physician Well-Being Index (ePWBI), an ePWBI ≥3 indicating poor wellbeing. Secondary outcomes included depressive symptoms, mental and physical health, and job satisfaction. We compared outcomes in part-time and full time workers using propensity score-adjusted multivariate regression models. RESULTS: Of 199 hospitalists invited, 137 (69%) responded to the survey, and 124 were eligible for analysis (57 full-time and 67 part-time clinicians). Full-time clinicians were more likely to have poor wellbeing compared to part-time clinicians (ePWBI ≥3 54% vs. 31%, p = 0.012). Part-time compared to full-time clinical work was associated with a lower risk of poor well-being in adjusted analyses (odds ratio 0.20, 95% confidence interval 0.07-0.59, p = 0.004). Compared to full-time clinicians, there were fewer depressive symptoms (3% vs. 18%, p = 0.006), and mental health was better (mean SF-8 Mental Component Summary score 47.2 vs. 43.2, p = 0.028) in part-time clinicians, without significant differences in physical health and job satisfaction. CONCLUSIONS: Full-time clinical hospitalists in GIM have a high risk of poor well-being. Part-time compared to full-time clinical work is associated with better well-being and mental health, and fewer depressive symptoms.

Histological remission of eosinophilic esophagitis under asthma therapy with IL-5 receptor monoclonal antibody: A case report.

BACKGROUND: Benralizumab is a monoclonal antibody targeting the IL-5 receptor used in the treatment of asthma. The use of benralizumab in other conditions is only emerging and could represent a therapeutic option for other eosinophil-associated diseases. Here, we report the case of a patient suffering from eosinophilic esophagitis and asthma who achieved histological remission of eosinophilic esophagitis (EoE) under benralizumab treatment for his asthma. CASE SUMMARY: Our patient was a 56-year-old white male with a history of eosinophilic esophagitis and severe asthma. After years of usual treatments, including topical steroids, biological treatment with mepolizumab, and standard asthma treatment, only poor control of both conditions was obtained. A control gastroscopy after the initiation of benralizumab showed complete histological remission of his EoE. CONCLUSION: Our case shows the effects of therapy with a novel agent not yet approved for this condition but for other diseases, with histological resolution of EoE after treatment. Complete clinical remission was not observed, which exemplifies the complex nature of EoE, its associated psychosomatic burden, and the chronification of the disease. Nevertheless, monoclonal antibodies targeting the Th2 response and, in our case, an IL5 receptor antagonist, achieved complete histological remission, which was not the case with an antibody against IL-5, which was also initiated to treat asthma.

Challenges in the diagnosis of marginal zone lymphoma with symptoms of small intestinal disease: a case report and scoping review of the literature.

Background: Marginal zone lymphoma can be accompanied by symptoms of small intestinal disease including abdominal pain and malabsorption. However, the best diagnostic approach for suspected marginal zone lymphoma is unknown and intestinal biopsies are frequently negative. We describe the case of a patient with symptoms of small bowel involvement where marginal zone lymphoma could only be detected upon peripheral lymph node resection. To assess the clinical variability of intestinal marginal zone lymphoma as a rare clinical entity, a scoping review with systematic literature research was performed. Methods: A 57-year-old man presented with a 10-year history of postprandial abdominal pain, systemic inflammation and recent weight loss. Endoscopies and a surgical small bowel specimen revealed non-specific findings. Flow cytometry from the bone marrow was highly suspicious for marginal zone lymphoma. A 2-18F-fluorodeoxyglucose-positron emission tomography/computed tomography (2-18F-FDG-PET/CT) showed hypermetabolic lymph nodes on both sides of the diaphragm. Cervical lymph node dissection finally confirmed marginal zone lymphoma. Immunochemotherapy yielded lasting oncological remission and resolved symptoms. We searched PubMed, Embase and Ovid MEDLINE® for additional case reports limited to the last 25 years. Five primary search terms combined using "AND" were used freely and as controlled vocabulary. Additional studies were identified by reviewing the reference lists of included articles. Results: Our review revealed 52 cases of marginal zone lymphoma with small intestinal manifestation. Patients presented with abdominal pain, bowel obstruction, weight loss or gastrointestinal bleeding. Diagnosis was mainly established by surgery (73%). The most frequent endoscopic findings were mucosal erosions and ulcerations. A 2-18F-FDG-PET/CT was positive in 9/15 patients. Treatment included rituximab, chemotherapy, surgery and/or radiation resulting in clinical remission in 82% of cases. Conclusions: Diagnostic workup for suspected small intestinal marginal zone lymphoma is challenging, necessitating a multidisciplinary approach. Endoscopy, imaging including 2-18F-FDG-PET/CT and small bowel resection or dissection of hypermetabolic lymph nodes can be useful. If marginal zone lymphoma is suspected vigorous diagnostic efforts are justified since remission can be achieved in most patients. Our review highlights the variable clinical presentation of this underdiagnosed disease and adds systematic data to the literature.

Aortic compression of the esophagus: A case report and literature review.

Distal aortic compression of the lower esophagus with consecutive dilatation of the proximal esophagus was first described in the literature in 1932. Here, the authors describe the case of a 66 year-old male complaining of gastroesophageal reflux. Due to a positive family history of carcinoma of the esophagus and compression of the dorsal esophagus during an esophageal barium swallow test, further tests were performed. Endoscopy and CT exam revealed a dilated esophagus due to compression of a crossing aorta. Because of mild symptoms and the absence of dysphagia, no further treatment was necessary except for the use of a proton pump inhibitor and recommended follow-ups every one to two years.

Admission glycaemia and outcome in patients with acute coronary syndrome.

Some studies of patients with acute myocardial infarction have reported that hyperglycaemia at admission may be associated with a worse outcome. This study sought to evaluate the association of blood glucose at admission with the outcome of unselected patients with acute coronary syndrome (ACS). Using the Acute Myocardial Infarction and unstable angina in Switzerland (AMIS Plus) registry, ACS patients were stratified according to their blood glucose on admission: group 1: 2.80-6.99 mmol/L, group 2: 7.00-11.09 mmol/L and group 3: > 11.10 mmol/L. Odds ratios for in-hospital mortality were calculated using logistic regression models. Of 2,786 patients, 73% were male and 21% were known to have diabetes. In-hospital mortality increased from 3% in group 1 to 7% in group 2 and to 15% in group 3. Higher glucose levels were associated with larger enzymatic infarct sizes (p<0.001) and had a weak negative correlation with angiographic or echographic left ventricular ejection fraction. High admission glycaemia in ACS patients remains a significant independent predictor of in-hospital mortality (adjusted OR 1.08; 95% confidence intervals [CI] 1.05-1.14, p<0.001) per mmol/L. The OR for in-hospital mortality was 1.04 (95% CI 0.99-1.1; p=0.140) per mmol/L for patients with diabetes but 1.21 (95% CI 112-1.30; p<0.001) per mmol/L for non-diabetic patients. In conclusion, elevated glucose level in ACS patients on admission is a significant independent predictor of in-hospital mortality and is even more important for patients who do not have known diabetes.

Conservative treatment of hepatic portal venous gas consecutive to a complicated diverticulitis: A case report and literature review.

INTRODUCTION AND PRESENTATION OF CASE: Eight days after being diagnosed with multiple small strokes a 71year old male patient is readmitted with suspicion of a petit mal seizure also complained of diarrhoea and abdominal pain. The patient was stable, not febrile and neurologically intact with a slight tenderness in the left lower quadrant. An ultrasound revealed presence of air in the hepatic portal venous system and a suspicion for sigmoid diverticulitis. A CT-scan confirmed both diagnoses. We proceeded with a conservative regimen under close observation. The clinical course and laboratory results were unremarkable. DISCUSSION: The review of the literature (PubMed database) triggered 685 items with only one clinical trial establishing a scoring system to detect adult individuals, which need operation. CONCLUSION: A pneumoportogram (hepatic portal venous gas, HPVG) is a very rare and usually associated with bowel ischemia and from poor prognosis. The last decades saw the emergence of numerous other aetiologies (also benign) with a shift of paradigm from systematic emergency laparotomies to individual patient selection.

Impact of hypertension on the outcome of patients admitted with acute coronary syndrome.

OBJECTIVE: The role of hypertension and its impact on outcome in patients with acute coronary syndrome (ACS) is still debated. This study aimed to compare the outcomes of hypertensive and nonhypertensive ACS patients. METHODS: Using data of ACS patients enrolled in the Acute Myocardial Infarction in Switzerland Plus Registry from 1997 to 2013, characteristics at presentation and outcomes in hospital and after 1 year were analyzed. Hypertension was defined as previously diagnosed and treated by a physician. The primary endpoint was mortality. Data were analyzed using multiple logistic regressions. RESULTS: Among 41 771 ACS patients, 16 855 (40.4%) were without and 24 916 (59.6%) with preexisting hypertension. Patients with preexisting hypertension had a more favorable in-hospital outcome [odds ratio (OR) in-hospital mortality 0.82, 95% confidence interval (CI) 0.73-0.93; P = 0.022]. The independent predictors of in-hospital mortality for patients with preexisting hypertension were age, Killip class greater than 2, Charlson Comorbidity Index greater than 1, no pretreatment with statins and lower admission systemic blood pressure. Preexisting hypertension was not an independent predictor of 1-year mortality in the subgroup of patients (n = 7801) followed: OR 1.07, 95% CI 0.78-1.47; P = 0.68. Independent predictors of mortality 1 year after discharge for the 4796 patients with preexisting hypertension were age, male sex and comorbidities. Angiotensin-converting enzyme inhibitors or angiotensin II receptor antagonists and statins prescribed at discharge improved the outcomes. CONCLUSION: Outcome of ACS patients with preexisting hypertension was associated with an improved in-hospital prognosis after adjustment for their higher baseline risk. However, this effect was not long-lasting and does not necessarily mean a causal relationship exists. Short-term and long-term management of patients with hypertension admitted with ACS could be further improved.
