BackgroundThe effective management of pain in chronic pancreatitis (CP) remains a therapeutic challenge. Analgesic drugs, such as opioids, and the underlying pathology can impair gut function. The autonomic nervous system influences hormone secretion and gut motility. In healthy volunteers, electrical (using noninvasive transcutaneous vagal nerve stimulation [t-VNS]) and physiological (using deep slow breathing [DSB]) modulation of parasympathetic tone results in pain attenuation and enhanced gut motility. Thus, the aims were to investigate whether t-VNS and DSB could enhance the parasympathetic tone, decrease pain sensitivity and improve gut motility in CP.Patients and methodsA total of 20 patients (12 males, mean age=61 years, range: 50–78 years) with CP were randomized to short-term (60 minutes) t-VNS and DSB, or their placebo equivalent, in a crossover design. Cardiometrically derived parameters of autonomic tone, quantitative sensory testing of bone and muscle pain pressure, conditioned pain modulation (CPM) and assessments of gastroduodenal motility with ultrasound were performed.ResultsIn comparison to sham, t-VNS and DSB increased cardiac vagal tone (CVT) (P<0.001). However, no changes in pain pressure thresholds for bone (P=0.95) or muscle (P=0.45) were seen. There was diminished CPM (P=0.04), and no changes in gastroduodenal motility were observed (P=0.3).ConclusionThis explorative study demonstrated that t-VNS and DSB increased CVT in patients with CP. However, this short-lasting increase did not affect pain sensitivity to musculoskeletal pain or gastroduodenal motility. The chronic pain in CP patients is complex, and future trials optimizing neuromodulation for pain relief and improved motility are needed.

Unrecognised MI is common among patients with schizophrenia and may contribute to the increased mortality found in this patient group.

HighlightsClear cell sarcomas are rare malignancies of the soft tissue.Clear cell sarcoma share characteristics with malignant melanoma, but modern techniques are able to distinguish the tumours.Timely and accurate primary diagnosis is important, as tumour size larger than 5 cm is correlated to a more sinister prognosis.Surgical treatment is imperative, the role of radiotherapy and chemotherapy remain unknown.Follow-up in a multidisciplinary setting is recommended.

It is unclear whether 12-lead ECG employing standard criteria for left ventricular hypertrophy (LVH) provides similar information with respect to long-term cardiovascular risk as echocardiography. The authors performed a retrospective cohort study of 1376 individuals without cardiovascular disease, who underwent ECG (LVH defined using the Sokolow-Lyon voltage combination (>35 mm) or the Cornell voltage-duration product (>2440 mm × ms)) and echocardiography (LVH defined as LV mass index (LVMI) >95 g/m 2 for women and >115 g/m 2 for men). The prognostic ability of LVH was assessed in Cox regression models adjusted for age, sex, smoking, systolic blood pressure, total cholesterol, antihypertensive medication, and fasting glucose. The primary end point was the composite of coronary events, heart failure, stroke, or death. The main secondary end point was heart failure or cardiovascular death. Median age was 67 (range 56-79) years, 68% were male. Eleven percent had ECG-defined LVH, 17% had echocardiographic LVH. Over median 8.5 years, 29% experienced a primary event. Event rates were 29%/35% for persons without/with ECG-defined LVH and 27%/39% for those without/with echocardiographic LVH. The Sokolow-Lyon combination, Cornell product, and ECG-defined LVH did not significantly predict the primary end point (P ≥ .05), but ECG-defined LVH predicted heart failure or cardiovascular death (adjusted hazard ratio (HR), 1.86, 95% confidence interval (CI), 1.13-3.08); P = .02). Conversely, LVMI was a significant, independent predictor of the primary end point (adjusted HR, 1.87, 95% CI, 1.13-3.10; P = .01), as was echocardiographic LVH (adjusted HR, 1.27, 95% CI, 1.01-1.61; P = .04). Echocardiographic LVH may be a better predictor of long-term cardiovascular risk than ECG-defined LVH in middle-aged and older individuals. 1648 | PEDERSEN Et al. 1 | INTRODUC TI ON Left ventricular hypertrophy (LVH) is a well-known risk factor for cardiovascular morbidity and mortality. 1-3 Early diagnosis is essential as regression of LVH is associated with a reduction in cardiovascular events. 4-6 Although several modalities are available for detection of LVH, ECG and echocardiography are most commonly used in daily clinical practice. ECG is easy to perform, but its specificity and, in particular, sensitivity are limited. On the other hand, echocardiography has a higher diagnostic accuracy, but is more expensive and time-consuming. 7-10 Contemporary guidelines for arterial hypertension and appropriate use criteria for echocardiography do not support universal application of echocardiography in patients with hypertension, but recommend its use when the results are likely to influence management. 10-12 However, it is unclear whether 12-lead ECG employing standard criteria for LVH provides similar information with respect to long-term cardiovascular risk as echocardiography. Data on direct prognostic comparisons remain scarce, though some studies have suggested potential advantages of echocardiography compared with ECG depending on the setting. 13-...

Clear cell sarcoma (CCS) previously known as malignant melanoma (MM) of the soft tissue, although, similar in morphology to MM, contemporary histopathologic and cytogenetic techniques have made this diagnosis obsolete, as it is now possible to distinguish between CCS and MM. CCS is often diagnosed in young adults with median age of 25 years. Overall mortality is generally poor, and the 5-year survival is between 40 and 60%. Hence, early diagnosis and radical surgery are key in the treatment of this extremely rare malignancy of the soft tissue comprising only about 1% of all sarcomas. This article present an overview of this rare malignancy.

The presented sham procedure provides a valid method for blinding of "sham acupuncture" and may be used in future blinded controlled trials of acupuncture for visceral pain.

The study presents proof-of-concept for the analgesic effect of acupuncture in pancreatic pain. Although the effect was short lasting, the framework may be used to conceptualize future trials of acupuncture in visceral pain.
