Transitional cell carcinoma of the bladder (TCC) represents nearly 90% of genitourinary malignancies and typically presents with locally invasive symptoms. Metastasis to the central nervous system (CNS) is uncommon occurring in <5% of patients. When present, metastatic lesions are typically solid, isolated and located in the cerebrum. We report a case of a patient with a history of TCC who presented with lethargy and ataxia and was found to have a solitary cystic cerebellar lesion consistent with metastatic disease. Unfortunately, the prognosis for patients with TCC and CNS metastases is poor. Treatment options include debulking surgery, whole brain radiation, stereotactic radiosurgery and chemotherapy. Unfortunately, treatment may not appreciably extend survival and care is often supportive in previously reported cases. Though uncommon, TCC can metastasise to the CNS and should be considered in the differential diagnosis of patients, particularly those who were treated with aggressive surgery or combination chemotherapy previously.

AbstractBackgroundThere is symptom overlap between gastro‐esophageal reflux disease (GERD) and functional dyspepsia (FD). We aimed to test the hypothesis that FD cases are now more likely mislabeled as GERD.MethodsIn subjects from Olmsted County, MN seen at Mayo Clinic: (i) Investigation of GERD and FD diagnosis rates between 1985 and 2009. (ii) Assessment of survey‐based upper gastrointestinal symptoms between 1988 and 2009. (iii) Analysis of patients reporting GERD and/or FD symptoms and subsequently receiving a consistent diagnosis of GERD and/or FD during a medical encounter. (iv) Assess the association between PPI use and GERD and/or FD symptoms and between actual diagnoses received.Key Results(i) Yearly GERD diagnosis rates rose between 1985 and 2009 (325–1866 per 100 000). FD diagnosis rates rose from 45 in 1985, to 964 in 1999 but decreased to 452 per 100 000 in 2009. (ii) Reported GERD symptoms did not significantly change between three survey waves in the years 1988–2009 (p = 0.052), whereas FD symptoms slightly increased (p = 0.01). (iii) 62.9% of subjects reporting GERD symptoms received a GERD diagnosis, however only 12.5% of subjects reporting FD symptoms received a FD diagnosis. (iv) PPI use was associated with documented GERD diagnosis (p < 0.001), however there was no significant association between GERD symptoms and PPI use (p = 0.078).Conclusions & InferencesWe have found evidence supporting a systematic bias away from diagnosing FD, favoring a GERD diagnosis.

Animal models have demonstrated that CD36 facilitates cell membrane free fatty acid (FFA) transport, but its role in human metabolism is not well understood. We measured heart, liver, adipose (three depots), and muscle (truncal postural and thigh locomotive) FFA uptake using [11C]palmitate positron emission tomography (PET) scans in a family of five carrying the Pro90Ser CD36 mutation (2 homozygotes had no CD36) and matched control volunteers. PET scans were done under conditions of suppressed and slightly increased palmitate concentrations. During suppressed palmitate conditions, muscle and adipose palmitate uptake were markedly reduced in homozygotes but not heterozygotes for the Pro90Ser CD36 mutation, whereas when palmitate concentration was slightly increased, uptake in muscle and adipose did not differ between control subjects and homozygous family members. Hepatic FFA uptake was similar in all participants regardless of palmitate concentrations, whereas myocardial FFA uptake was diminished in the Pro90Ser homozygotes during both suppressed and increased palmitate conditions. We conclude that CD36 1) facilitates FFA transport into muscle and adipose tissue in humans when extracellular concentrations are reduced but not when they are modestly elevated, 2) is not rate limiting for hepatic FFA uptake, and 3) is needed for normal cardiac FFA uptake over a range of FFA concentrations from low to slightly elevated.

A multidisciplinary panel of 18 physicians and 3 non-physicians from eight countries (Sweden, UK, Argentina, Australia, Italy, Finland, Norway and the USA) reviewed the literature on diagnosis and management of adult coeliac disease (CD). This paper presents the recommendations of the British Society of Gastroenterology. Areas of controversies were explored through phone meetings and web surveys. Nine working groups examined the following areas of CD diagnosis and management: classification of CD; genetics and immunology; diagnostics; serology and endoscopy; follow-up; gluten-free diet; refractory CD and malignancies; quality of life; novel treatments; patient support; and screening for CD.

AbstractObjectivesPatient throughput is an increasingly important cause of emergency department (ED) crowding. The authors previously reported shorter patient length of stay (LOS) when adding a triage liaison provider, which required additional personnel. Here, the objective was to evaluate the effect of moving a fast‐track provider to the triage liaison role.MethodsThis was a prospective observational before‐and‐after study design with predefined outcomes measures. A “standard staffing” situation (where an advanced practice provider staffed treatment rooms in the fast track) was compared with an advanced practice provider performing the triage liaison staffing role, with no additional staff. Eleven intervention (“triage liaison staffing”) days were compared with 11 matched control (“standard staffing”) days immediately preceding the intervention. Total LOS was measured for all adult Emergency Severity Index (ESI) 3, 4, and 5 patients (excluding behavioral health patients), and results were compared using Wilcoxon rank‐sum and chi‐square tests.ResultsA total of 681 patients registered on control days and 599 on intervention days. There was no significant difference in total patient LOS: median = 273 minutes, interquartile range (IQR) 176 to 384 minutes on intervention days versus median = 253 minutes, IQR = 175 to 365 minutes on control days (p = 0.20). There was no difference in left‐without‐being‐seen (LWBS) rates (n = 48, 7% on control days vs. n = 35, 6% on intervention days; p=0.38). Secondary analysis of only ESI 3 patients showed no difference in total LOS between periods (median = 284 minutes, IQR = 194 to 396 minutes on intervention days vs. median = 290 minutes, IQR = 217 to 397 minutes on control days; p = 0.22). There was, however, significantly greater total LOS for ESI 4 and 5 patients during the intervention period (median = 238 minutes, IQR = 124 to 350 minutes on intervention days vs. median = 192 minutes, IQR = 124 to 256 minutes on control days; p = 0.011).ConclusionsThe previously reported benefits on patient LOS and LWBS rates after adding a triage liaison (resource additive) were lost when that provider was moved from fast track to the triage role (resource neutral). While the triage liaison provider role may be a way to improve ED throughput when additional resources are available, as evidenced by our prior study, the triage liaison model itself does not appear to replace the staffing of treatment rooms, as evidenced by this study.

AbstractPurposeAssessment of hip internal rotation (IR) is a critical element in the evaluation of a painful hip, yet there currently exists no consistent method of determining this measurement. The purpose of this study is to report the intra‐rater and inter‐rater reliability of active and passive hip IR measurement using a digital inclinometer.MethodsTwenty‐five subjects (8 men, 17 women) with asymptomatic hip joints, and no known pathology between the ages of 22 and 42 participated. Two examiners measured hip IR for each subject using a digital inclinometer while visually monitoring pelvic motion. Measurements included passive IR, active IR, and active IR while internally rotating both legs simultaneously. Statistical analysis was performed including intra‐rater and inter‐rater reliability.ResultsThere was no significant difference in measured IR values. Mean range of motion values for all techniques and both examiners ranged from 30.7° to 32.8°. Intra‐rater reliability for examiner 1 ranged from 0.84 to 0.92. Inter‐rater reliability ranged from 0.89 to 0.93. Of the methods utilized, active IR of a single leg was the most responsive technique with a minimal detectable change value of 5.4°.ConclusionsClinical assessment of hip IR range of motion can be performed efficiently and reliably with a digital inclinometer along with visual monitoring of the pelvis for unwanted motion. Findings from this study support unilateral active hip IR in a seated position as a reliable and responsive technique for obtaining hip IR measurements.Level of evidenceIII.
