To determine the clinical value of radionuclide shuntography in the evaluation of adult hydrocephalic patients with suspected ventriculoperitoneal (V-P) shunt malfunction. All adult patients who underwent Tc-99m diethylenetriamine pentaacetic acid shuntographic scans at Far Eastern Memorial Hospital between August 2005 and December 2015 were included. Shuntographic results were visually evaluated in a simple qualitative manner: prompt flow that reached the peritoneum on 30-minute early images and diffuse peritoneal tracer distribution on 2-hour delayed images were interpreted as nonobstructive shunt flow...

PURPOSE: To assess the presence of outer and inner retinal folds (RFs) and drop-out of the ellipsoid zone (EZ) occurring after surgical repair of macula-off rhegmatogenous retinal detachment (RRD) with different postoperative posture and preoperative use of adjuvant perfluorocarbon liquid (PFCO). METHODS: In this prospective study, 56 eyes of 56 consecutive patients affected by RRD were subjected to 23- or 25-gauge pars plana vitrectomy (PPV). The patients were randomized in four groups (14 prone 5 hr without PFCO, 14 supine 5 hr without PFCO, 14 prone 5 hr with PFCO and 14 supine 5 hr with PFCO) and followed up with spectral domain optical coherence tomography (SD-OCT)...

Background For the new cystic fibrosis (CF) newborn screening program in Germany the Federal Joint Committee (G-BA) implemented a new screening protocol using immunoreactive trypsinogen (IRT) as first and pancreatitis associated protein (PAP) as second tier. Gene analysis with a panel of 31 CFTR-mutations is used as third tier to increase the positive predictive value (PPV) which is known to be low in pure biochemical IRT/PAP protocols. Methods For post hoc analysis the data pool (n=372 906) of a study evaluating a pure biochemical IRT/PAP protocol was used for assessment of the 3-step G-BA protocol in comparison with an alternative screening protocol recommended by the authors...

PURPOSE: The significance of the Risk of Ovarian Malignancy Algorithm (ROMA) in differentiating benign and malignant ovarian lesions has been evidenced. In our clinical work, we found that advanced ovarian cancer were accompanied commonly with high ROMA scores. Thus, this study aimed to clarify the performance of ROMA in different disease stage of epithelial ovarian cancer (EOC) prior to surgery. METHODS: Carbohydrate antigen (CA125) and human epididymis protein 4 (HE4) levels and ROMA scores in 221 patients with FIGO stage I, II or III/IV stage EOC were analyzed...

Blood-based interferon-gamma (IFN-γ) release assays (IGRAs) have been proven to be useful in the diagnosis of Mycobacterium tuberculosis (Mtb) infection. However, IGRAs have not been recommended for clinical practice in most low-income settings due to cost-intensive limitations and shortage of clinical data available. The established T-SPOT. TB assay containing Mtb-specific antigens ESAT-6 and CFP10 are widely used for immunodiagonsis of Mtb infection, but the high cost is one of the restricting factors against its clinical application in the developing countries...

GOALS: To raise awareness of the utility of flow cytometric detection of inflammatory markers in the early diagnosis of neonatal sepsis. PROCEDURES: In accordance with the Töllner scoring system, cases with ≥10 points are accepted as having "clinical sepsis" and cases with 0-4 points as having "no sepsis". The study group consisted of 50 newborns with clinical sepsis as well as a control group of 50 newborns without sepsis. In all cases, blood counts, C-reactive protein (CRP) levels, and procalcitonin (PCT) levels were recorded...

The electrode/organic interface is one of the crucial key factor to attain superior device performance in organic electronics, and inserting a tailor-made layer can dramatically modify its properties. Using of nano-composite (NC) materials lead to many advantages by combining the materials with the objective of getting desirable combination of properties. In this context, zinc oxide/polyethyleneimine (ZnO:PEI) NC film was incorporated as the interfacial layer into the inverted bottom-emission organic light emitting diodes (IBOLEDs) and fully optimized...

OBJECTIVES AND METHODS: Head injury is the most common trauma presentation to UK emergency departments, with around 1.2 million patients each year. The key management principal for this time critical illness remains early surgical intervention. With the development of handheld near-infrared spectroscopy (NIRS) devices, there is now the possibility of triaging and diagnosing these patients immediately, where computed tomography (CT) scanner is unavailable. NIRS has two related but distinct potential uses within clinical medicine...

BACKGROUND: Neoadjuvant treatment of HER2-positive breast cancer frequently leads to a pathologic complete response (pCR), which is associated with favourable long-term outcome. Treatment regimens typically consist of 6-9 cycles of trastuzumab-based chemotherapy, although many patients achieve early radiologic complete response (rCR). If rCR accurately predicts pCR, the number of chemotherapy cycles can possibly be reduced. METHODS: We performed a diagnostic accuracy study to determine the association between rCR and pCR in patients with stage II-III HER2-positive breast cancer treated with neoadjuvant trastuzumab-based chemotherapy at the Netherlands Cancer Institute...

OBJECTIVE: We aimed to compare the efficacy of Point-of-care ultrasonography (POCUS) with radiography in the diagnosis of tibia fracture (TF) and fibula fracture (FF), and determation of fracture characteristics. METHODS: Patients aged 5-55 years who were admitted to ED due to low-energy, simple extremity trauma, who had a suspected TF and FF on physical examination were included in this prospective study. One physician performed POCUS examination. Other physician evaluated the radiography images...

INTRODUCTION: External rotation and gravity stress radiographs have been described to distinguish stable supination-external rotation-II (SER-II) ankle fractures from unstable SER-IV fractures. It has been previously shown that both external rotation and gravity stress views are equivalent in their ability to diagnose deltoid ligament injury. It has also been shown that the position of the ankle influences the external rotation stress radiograph. However, no data of ankle position exist for gravity stress radiographs...

Objective.: To test the performance of the 2015 ACR-EULAR gout classification criteria against presence of SF MSU crystals in a primary healthcare population. Methods.: The criteria were applied to an existing dataset of consecutive patients with monoarthritis presenting to Dutch family physicians; all patients underwent microscopic SF analysis by design. The data had been prospectively collected to develop a diagnostic decision rule for gout in 2010. Diagnostic performance was assessed by calculating area under the receiver operating characteristic curve, sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and constructing calibration plots for the full version of the criteria (including SF analysis results of all patients) and the clinical-only version (not including SF analysis results)...

The aim of this study was to determine the prevalence of invasive aspergillosis (IA) in patients with liver cirrhosis and the performance of serum galactomannan (GM) screening. Patients with decompensated liver cirrhosis and patients with compensated liver cirrhosis presenting with fever and/or respiratory symptoms were prospectively enrolled. All patients were screened by serum GM twice weekly irrespective of clinical signs and symptoms. Positive serum GM triggered work-up consisting of chest computed tomography and in case of pathological findings bronchoscopy...
