Central post-stroke pain syndrome (CPSP) is a debilitating sequel that can follow thalamic sensory stroke. Less well recognized, CPSP follows lateral medullary stroke and parietal cortical stroke and may develop anywhere along the spinothalamic or trigemino-thalamic pathways. Patients describe sharp, stabbing, or burning pain and experience hyperpathia and especially allodynia. Although CPSP was first described over 100 years ago, CPSP is too frequently underrecognized. It is treatable disorder. Pharmacological therapy, magnetic stimulation, and invasive electrical stimulation are reviewed and recommendations made.

Our results suggest that VEGF may predict response to antidepressant treatment and may ultimately prove to be a potential biomarker that can be measured with a routine blood draw at the point of service.

BackgroundDirect observation of medical students with actual patients is important for the assessment of clinical skills including interviewing and counseling skills. This article describes medical students’ experience of mini-clinical evaluation exercise (mini-CEX) during their clerkship in consultation psychiatry.Materials and methodsIn our center during inpatient consultation psychiatry clerkship, all rotating students are expected to complete one mini-CEX assessment as part of their clinical training. We conducted retrospective analysis of mini-CEX ratings completed from 2013 to 2016. All evaluations took place at inpatient medical setting in patients admitted with medical conditions and psychiatric comorbidities.ResultsA total of 113 evaluations were reviewed. The time examiner observed the interaction of a student with the patient was 14.24 minutes (mean), and the time spent in providing feedback to the student was 9.71 minutes. Complexity of problem was rated as low in 0.88% (n=1), moderate in 50.44% (n=57), and high in 48.67% (n=55). Highest ratings were for professionalism, similar to previous reports. Total score calculated by examiner showed no difference by the complexity of the patient; however, we observed a trend in higher counseling score for the high complexity group.ConclusionMini-CEX assessment during busy clerkship is feasible with good outcomes. Direct observation of medical trainees with actual patients is important for the assessment of performance-based clinical skills. Hospital psychiatry rotation covering various medical and surgical units offers a great opportunity for exposure in patient communication.

Document recommendation systems for locating relevant literature have mostly relied on methods developed a decade ago. This is largely due to the lack of a large offline gold-standard benchmark of relevant documents that cover a variety of research fields such that newly developed literature search techniques can be compared, improved and translated into practice. To overcome this bottleneck, we have established the RElevant LIterature SearcH consortium consisting of more than 1500 scientists from 84 countries, who have collectively annotated the relevance of over 180 000 PubMed-listed articles with regard to their respective seed (input) article/s. The majority of annotations were contributed by highly experienced, original authors of the seed articles. The collected data cover 76% of all unique PubMed Medical Subject Headings descriptors. No systematic biases were observed across different experience levels, research fields or time spent on annotations. More importantly, annotations of the same document pairs contributed by different scientists were highly concordant. We further show that the three representative baseline methods used to generate recommended articles for evaluation (Okapi Best Matching 25, Term Frequency–Inverse Document Frequency and PubMed Related Articles) had similar overall performances. Additionally, we found that these methods each tend to produce distinct collections of recommended articles, suggesting that a hybrid method may be required to completely capture all relevant articles. The established database server located at https://relishdb.ict.griffith.edu.au is freely available for the downloading of annotation data and the blind testing of new methods. We expect that this benchmark will be useful for stimulating the development of new powerful techniques for title and title/abstract-based search engines for relevant articles in biomedical research.

Background: Noncardiac chest pain (NCCP) is defined as persistent angina-like chest pain with no evidence of cardiac disease. There is some controversy about the long-term morbidity and mortality outcomes of NCCP patients. Many studies have found no significant differences in death rates in chest pain patients without coronary artery disease compared to the general population. However, studies that include longer follow-up periods and a better characterization of the NCCP population reveal a twofold elevation in the relative risk of adverse cardiac events over 5-26 years. This review sought to identify studies in relation to cardiovascular and psychological prognosis of NCCP patients. Methods: PubMed database and reference lists from relevant publications were reviewed. Inclusion criteria were systematic reviews, prospective studies, and retrospective surveys from 1970 to 2011. Search terms were as follows: chest pain, noncardiac chest pain, nonspecific chest pain, unexplained chest pain, prognosis of noncardiac chest pain, prognosis of angina with normal angiography, and angina with normal coronary arteries. Results: Studies supporting worse outcome (cardiac morbidity and mortality; n=16) included 173,875 patients with mean age 57 and mean length of follow-up 7.5 years. Studies supporting good outcome (n=25) included 244,998 patients with age 50 and length of follow-up 5 years. Articles supporting poor psychological outcome (n=9) included 3,987 patients and length of follow-up 2 years. Conclusion: There are mixed data on long-term morbidity, cardiovascular adverse events, and mortality of NCCP patients. Some studies provide supporting evidence for poor outcome, while others provide evidence for positive outcome. However, many patients with NCCP have prolonged psychosocial comorbidity. The heterogeneity of NCCP and study populations limited definitive conclusions. However, many patients with NCCP have psychiatric morbidity and poor quality of life. Several questions remain about NCPP with respect to the psychopathology and pathophysiology of this condition. Whether NCCP patients have good or bad outcome requires careful risk stratification.
