Distal pancreatectomy with multivisceral resection: A retrospective multicenter study - Case series.

2020

Abstract Background Multivisceral resection (MVR) is sometimes necessary to achieve disease-free margins in cancer surgery. In certain patients with pancreatic tumors that invade neighboring organs these must be removed to perform an appropriate oncological surgery. In addition, there is an increasing need to perform resections of other organs like liver not directly invaded by the tumor but which require synchronous removal. The results of MVR in pancreatic surgery are controversial. Material and methods A distal pancreatectomy retrospective multicenter observational study using prospectively compiled data carried out at seven HPB Units. The period study was January 2008 to December 2018. …

Multichannel functional testing in normal subjects, glaucoma suspects, and glaucoma patients

2012

Purpose.: To evaluate visual function with a novel multichannel functional test named the ATD Multichannel Functional Test. Methods.: This multicenter study had a prospective and cross-sectional design. A total of 186 eyes were included: 42 with glaucoma, 14 glaucoma suspects due to optic nerve characteristics, 25 ocular hypertensives, and 105 normal eyes. All patients performed standard visual fields (Humphrey 24-2) and ATD with eight stimuli configurations: four achromatic (A), two red-green (T), and two blue-yellow (D). To derive main outcome measures, mean sensitivity, mean defect (MD), and pattern standard deviation (PSD) were calculated and compared among groups and types of stimuli w…

Academia in cardiovascular radiology: are we doing enough for the future of the subspecialty?

2021

Aim To explore barriers to academic activities that cardiovascular radiology-oriented radiology trainees face worldwide. Materials and methods An international call for participation in an online survey was distributed via social media and radiological societies to radiology trainees. Questions covered barriers and involvement in academic activities during radiology training. Participants interested in cardiovascular radiology were selected for analysis with appropriate statistical methods. Results Of the 892 respondents, 120 (13.5%) reported an interest in cardiovascular imaging. The majority (63.3%, 76/120) were from Europe and 57.5% (69/120) were men. There were gender discrepancies in a…

Pseudoachalasia: a case series and analysis of the literature.

2005

Pseudoachalasia frequently cannot be distinguished from idiopathic achalasia by manometry, radiologic examination or endoscopy. Mechanisms proposed to explain the clinical features of pseudoachalasia include a circumferential mechanical obstruction of the distal esophagus or a malignant infiltration of inhibitory neurons within the myenteric plexus.Between January 1980 and December 2002, the clinical features of 5 patients with pseudoachalasia and 174 patients with primary achalasia, diagnosed in a single center, were compared. A literature analysis of the etiology of pseudoachalasia for the time period 1968 to December 2002 was performed. The search concentrated on the databases and online…

Intensive chemotherapy with idarubicin, ara-C, etoposide, and m-AMSA followed by immunotherapy with interleukin-2 for myelodysplastic syndromes and h…

2000

Intensive chemotherapy followed by treatment with interleukin-2 (IL-2) was evaluated in a prospective, randomized, multicenter trial including 18 patients with refractory anemia with excess of blasts in transformation (RAEB-T), 86 patients with acute myeloid leukemia (AML) evolving from myelodysplastic syndromes, and six patients with secondary AML after previous chemotherapy. Median age was 58 years (range: 18-76 years). Forty-nine patients (45%) achieved a complete remission (CR) after two induction cycles with idarubicin, ara-C, and etoposide, 52% of them aged/=60 years and 35% aged60 years (p=0.06). After two consolidation courses, patients were randomized to four cycles of either high-…

Add-on Antidepressants in the Naturalistic Treatment of Schizophrenia Spectrum Disorder – When, Who, and How?

2017

Abstract The aim of this study was to evaluate antidepressant add-on treatment within the acute treatment of schizophrenia spectrum disorder patients. Antidepressant add-on was evaluated in 365 patients within a naturalistic multicenter study. Patients with/without antidepressant add-on were compared regarding clinical and treatment-related variables, response and remission, and remission of depressive and negative symptoms. The efficacy of antidepressant add-on treatment was furthermore analyzed applying marginal structure models. Twenty-three percent of the patients received antidepressant add-on for a mean duration of 50.28 (33.42) days. Patients with the diagnosis of a schizoaffective d…

Postural Control Mechanisms in Healthy Adults in Sitting and Standing Positions

2015

This study explored differences in the center of pressure in healthy people in a sitting and standing position and with eyes open and closed. With this purpose, 32 healthy participants (16 men, 16 women; M age = 25.2 yr., SD = 10.0, range = 18–55) were measured with an extensiometric force plate. Using a two–way repeated-measures multivariate analysis of variance (MANOVA), the root mean square, velocity, range, and sway, in both visual conditions, had higher values in the standing task than in the sitting task. In the frequency domain, the low-frequency band had higher values during the standing task. For control mechanism variables, mean distance and time were greater when standing while …

Dynamic posturography findings predict balance status in vestibular schwannoma patients.

2007

OBJECTIVE To test whether condition 5 score (C5S) and condition 6 score (C6S) of the sensory organization test of computerized dynamic platform posturography (CDPP) differ between vestibular schwannoma (VS) patients with and without vestibular symptoms. STUDY DESIGN Retrospective review of prospectively collected data. SETTING Tertiary academic referral center. PATIENTS Two hundred and sixteen consecutive patients with a histological diagnosis of a VS (103 women; 113 men; age range, 18-78 years; median, 54 years) who had been preoperatively evaluated by CDPP. A hundred and twelve patients had a history of vertigo, dizziness, and/or imbalance, and 104 patients had neither present nor past ve…
