As emergency department (ED) crowding continues to worsen, many visits are at academic referral hospitals. As a result, engaging specialty services will be essential to decompressing the ED. To do this, it will be important to understand which specialties to focus interventions on for the greatest impact. ⋯ Nearly 18% of all patients that have a specialist and are treated and discharged from the ED present with a diagnosis related to their specialist's practice. This may indicate that there is a role for specialty service to play in decreasing some ED utilization that may be appropriate for the out-patient clinical setting. By focusing attention on specific specialties and interventions targeted during office hours, there may be an opportunity to decrease ED utilization.

Observational Study
Associated vitamin D deficiency is a risk factor for the complication of HCV-related liver cirrhosis including hepatic encephalopathy and spontaneous bacterial peritonitis.
The influence of vitamin D, 25-hydroxyvitamin D (25(OH)D), deficiency on hepatitis C virus (HCV)-related cirrhosis had been poorly elucidated especially in patients with hepatic encephalopathy (HE) and spontaneous bacterial peritonitis (SBP). We aimed to investigate the association between vitamin D deficiency and the risk of SBP or HE, including the mortality rate. Serum 25(OH)D levels were prospectively determined in 135 patients. ⋯ Serum 25(OH)D levels < 5 ng/ml were associated with significant higher mortality rate (HR = 2.76, P = 0.001). Lower 25(OH)D levels were associated with HE and SBP in cirrhotic patients. In addition, it may be considered a prognostic parameter for the severity of liver cirrhosis.

The clinical significance of pleural effusions (PLEs) in the setting of acute pericarditis remains poorly investigated. We sought to identify predictive factors for PLEs and their association with the short- and long-term prognosis of patients with acute pericarditis. We enrolled 177 patients hospitalized with a first episode of acute pericarditis. ⋯ We conclude that PLEs are common in patients hospitalized with a first episode of acute pericarditis. They are related to the intensity of inflammatory reaction, and they should not be considered necessarily as a marker of secondary etiology. Bilateral PLEs are associated with increased risk of in-hospital cardiac tamponade, but do not affect the long-term risk of pericarditis recurrence.

The Endoplasmic reticulum aminopeptidase protein 1 (ERAP1) trims N-terminal amino acids from epitope precursors for Major Histocompatibility Complex class I presentation. Genome-wide association studies demonstrated that ERAP1 gene single nucleotide polymorphisms (SNPs) are associated with Behçet's syndrome (BS). This study was conducted on the two most consistently BS-associated ERAP1 polymorphisms, rs17482078 (NG_027839.1:g.35983G>A) and rs27044 (NG_027839.1:g.35997C>G) to analyse their distribution in 55 Italian BS patients and 65 ethnically matched controls (healthy controls, HC) and to test their association with BS risk. ⋯ No association was found between HLA-B*51 and both ERAP1 SNPs. Although preliminary, our data show a stronger association of rs17482078 with BS compared to rs27044 by means of case-control genetic analysis and bioinformatics prediction of protein structure change. A larger series of patients and controls is required to confirm our preliminary findings.

Pathergy phenomenon is a non-specific tissue hyperreactivity reaction due to trauma and is a minor diagnostic criterion of Behcet's disease. In this study, 100 patients with a suspicion of Behcet's disease who were referred to Cerrahpasa Medical Faculty Dermatology department between 01.11.2014 and 31.01.2015 are included. Skin pathergy tests were applied to all the patients and results were evaluated by two dermatologists separately at 48th hour, each with naked eye and with dermatoscopy. ⋯ However, naked eye results of doctor number 1 and 2 for the same patients were significantly different from each other (p 0.0372) and with dermatoscopy examination this difference was eliminated (p > 0.05). This study revealed that naked eye evaluation of pathergy test results can yield different results among different interpreters. Use of dermatoscopy during the evaluation process decreases interobserver variation and subjectivity of the test.
