RATIONALE AND OBJECTIVES Hydrocephalus (HC) is caused by accumulating cerebrospinal fluid resulting in enlarged ventricles and neurological symptoms. signaling pathway HC can be treated via a shunt in a subset of patients; identifying which individuals will respond through noninvasive imaging would avoid complications from unsuccessful treatments. This preliminary work is a longitudinal study applying MR Elastography (MRE) to HC patients with a focus on normal pressure hydrocephalus (NPH). MATERIALS AND METHODS Twenty-two ventriculomegaly patients were imaged and subsequently received a lumbar drain placement for cerebrospinal fluid (CSF) drainage. NPH lumbar drain responders and NPH syndrome nonresponders were categorized by clinical presentation. Displacement images were acquired using intrinsic activation (IA) MRE and poroelastic inversion recovered shear stiffness and hydraulic conductivity values. A stable IA-MRE inversion protocol was developed to produce unique solutions for both recovered properties, independent of initial estimates. RESULTS Property images showed significantly increased shear modulus (p = 0.003 in periventricular region, p = 0.005 in remaining cerebral tissue) and hydraulic conductivity (p = 0.04 in periventricular region) in ventriculomegaly patients compared to healthy volunteers. Baseline MRE imaging did not detect significant differences between NPH lumbar drain responders and NPH syndrome nonresponders; however, MRE time series analysis demonstrated consistent trends in average poroelastic shear modulus values over the course of the lumbar drain process in responders (initial increase, followed by a later decrease) which did not occur in nonresponders. CONCLUSION These findings are indicative of acute mechanical changes in the brain resulting from CSF drainage in NPH patients. BACKGROUND The presence of synchronous benign and malignant salivary gland neoplasms is very rare. The authors present a previously unreported combination of Secretory Carcinoma (SC) and Warthin's Tumor (WT) within the same parotid gland. METHODS The patient presented with increasingly painful enlargement of the left parotid gland. CT scan with contrast revealed a heterogeneous solid/cystic mass in the superficial lobe. Fine needle aspiration cytology favored pleomorphic adenoma (PA) and patient underwent superficial parotidectomy without complication. RESULTS Final pathology revealed concomitant presence of SC and WT. Stains were positive for S100 and mammaglobin, and FISH revealed the presence of t(12;15) (p13;q25) translocation, resulting in the ETV6-NTRK3 fusion gene. CONCLUSION It is important for surgeons and pathologists to note the potential for co-existing benign and malignant pathology within the same salivary gland, as this can have an impact on management and prognosis for patients. A patient suffering from acute promyelocytic leukemia (APL) was referred to the dental department before introduction of chemotherapy by all-trans retinoic acid and arsenic trioxide (ATO). A panoramic radiography showed his third upper maxillary left tooth included into the maxillary bone. signaling pathway The patient presented with a febrile episode. Consequently, the infectious gateway was researched. A left maxillary sinus migration of his third upper left tooth together with a bony sequestrum has been observed on a CT-scan. A surgery was then performed to remove the bony sequestrum and the tooth. The first hypothesis of tooth migration could be that the patient had an infection prior to introduction of chemotherapy. However, neither clinical or radiographic signs were observed during the initial check-up. The second hypothesis is that ATO caused osteonecrosis of the jaw (ONJ) induced the formation of a bony sequestrum associated to the tooth migration into the sinus. ONJ could be a potential adverse of ATO chemotherapy. BACKGROUND Carbon monoxide (CO) is one of the major causes of poisoning worldwide. We aimed to investigate the efficacy of the continuous positive airway pressure (CPAP) use in CO poisoning. METHODS After CO poisoning, one group of patients was treated with a non-rebreather mask (NRB) and another group using the CPAP mode of mechanical ventilation (CPAP). All patients received at least 90 minute treatment. The carboxyhemoglobin saturation (SpCO) levels of all patients were measured from the fingertips with a portable CO-oximeter at 0, 30, 60 and 90 min. The rates of changes in the serially measured SpCO values were obtained using the Wilcoxon signed-rank test. RESULTS A total of 45 patients (24 in NRB and 21 in CPAP group) completed the study. The median initial SpCO levels were 24% (21-33) in NRB group, 25% (21-32) in CPAP group, with no statistically significant difference (p 0.323). At the 30th, 60th, and 90th minutes of treatment, significantly lower values were obtained from CPAP than NRB (p  less then  0.001). The COHb half-life was decreased significantly by CPAP [105(70-190) vs 45(30-120), p  less then  0.001]. In CPAP group, the fastest decline in the SpCO level was observed for the interval of 0-30 min [Median difference 8(3-14), p  less then  0.001]. CONCLUSIONS CPAP lowered the amount of CO in the blood faster than the mask; therefore, it may be effective in the treatment of CO poisoning. BACKGROUND Emergency departments (ED) in the United States see more than half a million atrial fibrillation visits a year, however guideline recommended anticoagulation is prescribed in less then 55% of eligible patients. OBJECTIVE The purpose of this study was to measure guideline recommended anticoagulation prescribing in patients with nonvalvular atrial fibrillation (NVAF) presenting to the ED, with the goal of closing any treatment gap established. METHODS We conducted an observational, prospective cohort study in consecutive patients presenting to the ED with a diagnosis of NVAF. CHA2DS2-VASc and HAS-BLED scores were calculated and used as predefined criteria to establish guideline-based oral anticoagulation compliance in comparing routine care (baseline cohort) versus a multidisciplinary team approach. Transition of Care (TOC) services and follow-up were also provided in the multidisciplinary cohort. The primary endpoint was to compare the proportion of patients on guideline based oral anticoagulant (OAC) therapy at admission and discharge between the groups.
