B‐Mode ultrasonography of the paranasal sinuses compared with CT findings
1992
Ultrasound as a diagnostic aid in the evaluation of the sinuses has been a controversial issue. Sensitivities have been reported from 29% to 100% and specificities from 55% to 99%. These wide variations in results from previous studies may have resulted from technical differences. However, the "gold standard" most often used for comparison has been a Water's view radiograph, which has been shown to correlate poorly with intraoperative and CT scan findings. To our knowledge, no one in the English language literature has evaluated sonography of the sinuses with computed tomography as the gold standard. In addition, evaluation of the ethmoid sinus has been neglected by previous studies that ha…
Meniscal ramp lesions: diagnostic performance of MRI with arthroscopy as reference standard
2021
Abstract Background The posteromedial meniscal region is gaining interest among orthopedic surgeons, as lesions of this area has been reported to be significantly associated with anterior cruciate ligament tears. The current imaging literature is unclear. Purpose To evaluate the diagnostic performance of MR in the detection of meniscal ramp lesions having arthroscopy as reference standard. Materials and methods We retrospectively included 56 patients (mean age of 25 ± 7 years; 14 females) from January to November 2017 with a arthroscopically proved ACL tear and posterior meniscocapsular separation. On preoperative MRI, two radiologists with 13 and 2 years’ experience in musculoskeletal imag…
The shoulder medial rotation test: an intertester and intratester reliability study in overhead athletes with chronic shoulder pain.
2013
The purpose of this study was to examine intertester and intratester reliability of the shoulder medial rotation test (MRT) and reliability differences depending on examiner expertise.Seventeen athletes with chronic shoulder pain participated in the study. Four independent observers with different experience levels simultaneously rated MRT performance as "correct" or "incorrect," after a standardized assessment protocol, the same day (for intertester reliability) and in a 7-day interval (for intratester reliability).The intrarater reliability was admissible for 2 experts and one novice, with κ values ranging between 0.32 to 0.76 and poor for one novice (κ0). Interrater agreement for all 4 a…
URINARY DIVERSION AND ORTHOTOPIC BLADDER SUBSTITUTION IN CHILDREN AND YOUNG ADULTS WITH NEUROGENIC BLADDER: A SAFE OPTION FOR TREATMENT?
2000
Combined pharmacotherapy, clean intermittent catheterization and infection prophylaxis is currently the gold standard of treatment for neurogenic bladder. However, as the adolescent gains independence from parental supervision, the intervals of clean intermittent catheterization compliance with medical treatment and regularity of followup examinations may decrease, and neurological and/or orthopedic status may change. This situation sometimes leads to failure of conservative treatment, resulting in incontinence and/or deterioration of the upper urinary tract. A multidisciplinary team was established at our institution 30 years ago to assess all aspects of care for patients with neurogenic b…
Relationship between video head impulse test (vHIT) and caloric test in patients with vestibular neuritis.
2016
Abstract Introduction and objectives The caloric test is the gold standard for the loss of vestibular function diagnosis. The video head impulse test (vHIT) assesses the same reflex by using a video-assisted examination of the impulsive manoeuvre. We intend to compare the variation of results of the vHIT and the caloric test in patients with vestibular neuritis with respect to their initial condition at two different moments of their evolution and to check the level of correlation between them and with that of the DHI test. Methods We explored 20 patients with neuritis by using both vHIT and the caloric test on the same day. We assessed the correlation between these two tests and with the D…
Correlation between cell free DNA levels and medical evaluation of disease progression in systemic lupus erythematosus patients
2014
High levels of cell free DNA (cfDNA) in human blood plasma have been described in patients with autoimmune diseases. The aim of this study was to determine the levels of cfDNA in systemic lupus erythematosus (SLE) patients and to assess fluctuations of cfDNA concentrations compared to the course of disease progression under standard treatment. Therefore, nuclear cfDNA concentrations in plasma were measured in 59 SLE patients and 59 healthy controls. Follow-up blood plasma was collected from 27 of the 59 SLE patients. Patients were characterised by clinical parameters (antinuclear antibodies (ANA), anti-dsDNA-antibodies, C3, C4, and CRP), SLE disease activity index (SLEDAI) and medical thera…
Adjuvant vs. neoadjuvant radiochemotherapy for locally advanced rectal cancer: the German trial CAO/ARO/AIO-94.
2003
Aim The standard treatment for patients with clinically resectable rectal cancer is surgery. Postoperative radiochemotherapy (RCT) is recommended for advanced disease (pT3/4 or pN+). In recent years, encouraging results of pre-operative radiotherapy have been reported. This prospective randomized phase-III-trial (CAO/ARO/AIO-94) compares the efficacy of neoadjuvant RCT to standard postoperative RCT. We report on the design of the study and first results with regard to toxicity of RCT and postoperative morbidity. Patients and methods Patients with locally advanced operable rectal cancer (uT3/4 or uN+, Mason CS III/IV) were randomly assigned to pre or postoperative RCT: A total dose of 50.4…
Prospective randomized comparison of short-access mother-baby cholangioscopy versus direct cholangioscopy with ultraslim gastroscopes
2012
Mother-baby technologies, the criterion standard for cholangioscopy, have several limitations. A novel, short-access, mother-baby (SAMBA) system may improve this technique. Direct cholangioscopy (DC) was recently developed as an alternative to mother-baby cholangioscopy.Comparison of success rates with SAMBA and DC.Single-center, randomized, controlled trial.Academic tertiary-care referral center.Sixty patients with suspected cholangiopathies randomized to either SAMBA (n = 30) or DC (n = 30).Cholangioscopy under deep sedation.Technical success rate of diagnostic or therapeutic procedure.A total of 24 and 21 diagnostic procedures were performed in the SAMBA and DC groups, respectively. Ther…
The screen for cognitive impairment in psychiatry: diagnostic-specific standardization in psychiatric ill patients
2013
Abstract Background The Screen for Cognitive Impairment in Psychiatry (SCIP) is a simple and easy to administer scale developed for screening cognitive deficits. This study presents the diagnostic-specific standardization data for this scale in a sample of schizophrenia and bipolar I disorder patients. Methods Patients between 18 and 55 years who are in a stable phase of the disease, diagnosed with schizophrenia, schizoaffective disorder, schizophreniform disorder, or bipolar I disorder were enrolled in this study. Results The SCIP-S was administered to 514 patients (57.9% male), divided into two age groups (18–39 and 40–55 years) and two educational level groups (less than and secondary or…
Optimizing endovascular stroke treatment: removing the microcatheter before clot retrieval with stent-retrievers increases aspiration flow
2016
BackgroundFlow control during endovascular stroke treatment with stent-retrievers is crucial for successful revascularization. The standard technique recommended by stent-retriever manufacturers implies obstruction of the respective access catheter by the microcatheter, through which the stent-retriever is delivered. This, in turn, results in reduced aspiration during thrombectomy. In order to maximize aspiration, we fully retract the microcatheter out of the access catheter before thrombectomy—an approach we term the ‘bare wire thrombectomy’ (BWT) technique. We verified the improved throughput with systematic in vitro studies and assessed the clinical effectiveness and safety of this metho…
