Synchronous parenchymal renal tumors of different histology in the same kidney
2009
Background: Synchronous primary cortical tumors of different histology in the same kidney are rare. Preoperative awareness of this coexistence is important, since it can help in planning the surgical approach. Purpose: To describe the imaging findings observed in five patients with two parenchymal malignant tumors of different histology in the same kidney. Material and Methods: We reviewed the pathology reports of 381 patients operated for renal tumors from January 2000 to March 2007. The medical records of all patients with multiple, synchronous, primary lesions of different histology in the same kidney were reviewed with special attention to imaging findings and indications on the nature…
Incidence of Narcolepsy in Germany
2015
Study objectives Following the 2009 pandemic, reports of an association between an AS03 adjuvanted H1N1 pandemic influenza vaccine and narcolepsy were published. Besides determining background incidence rates for narcolepsy in Germany this study aimed at investigating whether there was a change in incidence rates of narcolepsy between the pre-pandemic, pandemic, and the post-pandemic period on the population level. Design Retrospective epidemiological study on the incidence of narcolepsy with additional capture-recapture analysis. Setting German sleep centers. Patients or participants Eligible were patients with an initial diagnosis of narcolepsy (ICD10 Code G47.4) within the period from Ja…
Effects of cumulative sleep restriction on self-perceptions while multitasking
2012
Summary This study addressed a rarely studied question of self-perceptions of performance and overall functional state during cumulative sleep restriction and the ensuing recovery period. Twenty healthy male volunteers, aged 19–29 years, were divided into a sleep restriction group (n = 13) and a control group (n = 7). On the first 2 nights, the sleep restriction group had an 8-h sleep opportunity that was restricted to 4 h for the next 5 nights, and then restored to 8 h for the last 2 nights. The control group had an 8-h sleep opportunity each night. Each day participants accomplished 50-min multitask sessions and gave self-ratings in their connection. Similar to our previous findings on mu…
Evaluation of surgical decision making and resulting outcome in patients with highly eloquent glioblastoma: Results of a multicenter assessment.
2017
Treatment of glioblastoma(GB) patients amenable only for a subtotal resection(STR) is controversial. Since outcome of patients is affected by surgical management, our aim was to assess surgical decision making and resulting outcome in patients with highly eloquent GBs.We retrospectively assessed GB patients with intended sub-total resection (STR) or stereotactic biopsy (STX) of 3 neurooncological centers operated between 2008 and 2013. A volumetric assessment of overall extent of resection(oEoR), presence of complications, new permanent neurological deficits(nPNDs) was performed. A central reviewer reassessed all cases blinded and gave recommendation on surgical management and on a potentia…
Durability of open popliteal artery aneurysm repair
2014
Objective The objective of this study was to analyze our long-term results after open surgery for popliteal artery aneurysm. Methods Records of patients who received surgery between 1998 and 2010 were retrieved from a computerized database and analyzed retrospectively. End points of the study were perioperative mortality and morbidity and patency and limb salvage rate. Results Two hundred and six popliteal aneurysms (median diameter, 30 mm; interquartile range, 18 mm) were treated (161 elective, 45 emergent) in 154 patients (mean age, 67 ± 11 years) using vein grafts (82%) via the medial approach (92%). Above-knee popliteal artery (45%) and below-knee popliteal artery (65%) were the predomi…
Efficacy of low level laser therapy in reducing postoperative pain after endodontic surgery-- a randomized double blind clinical study.
2004
The aim of the study was to evaluate the effect of low level laser application on postoperative pain after endodontic surgery in a double blind, randomized clinical study. Fifty-two healthy adults undergoing endodontic surgery were included into the study. Subsequently to suturing, 26 patients had the operation site treated with an 809 nm-GaAlAs-laser (oralaser voxx, Oralia GmbH, Konstanz, Germany) at a power output of 50 mW and an irradiation time of 150 s. Laser treatment was simulated in further 26 patients. Patients were instructed to evaluate their postoperative pain on 7 days after surgery by means of a visual analogue scale (VAS). The results revealed that the pain level in the laser…
Some biomechanical aspects of the foot and ankle in athletes with and without shin splints
1983
Thirteen adult male athletes (long-distance runners and orienteerers without foot problems) and 35 male ath letes with shin splints were compared with respect to: 1) the position of the lower leg and the heel while standing, 2) the passive range of mobility in the subtalar joint, and 3) the angular displacement between the calcaneus and the midline of the lower leg (Achilles tendon angle) while running with bare feet on a tread mill. In standing, the two groups differed statistically significantly in the Achilles tendon angle, which values were greater in the shin splint group. With respect to passive mobility, the athletes with shin splints had significantly greater (P < 0.05-0.01) ang…
Pandemic influenza A (H1N1) infection in pregnant and nonpregnant women in Spain (2009-2010)
2014
The present study aimed to compare the main features of infection with pandemic influenza A virus in pregnant and nonpregnant women admitted to hospitals in Spain during the first waves of the 2009-2010 influenza pandemic. This was a prospective (November 2009 to June 2010), multicenter observational study. All cases were women of reproductive age who had not been vaccinated against seasonal or pandemic influenza A. Influenza infection was confirmed by reverse transcription-polymerase chain reaction (RT-PCR). The sociodemographic and clinical data of all cases were reviewed. A total of 219 inpatients, including 49 pregnant women and 170 nonpregnant women, were enrolled in the study upon adm…
Results of closed subtalar dislocations.
2015
Background The subtalar dislocation (SD) of the foot is an uncommon injury characterized by a simultaneous dislocation of talocalcaneal and talonavicular joints without involvement of the tibiotalar and calcaneocuboid joints. Purposes The purpose of this study was to evaluate the clinical and radiological outcome in a consecutive series of close SD. Methods We retrospectively evaluated a case series of patients who presented a close SD. Thirteen patients were selected for this study. There were 9 patients with a medial SD, 3 patients with a lateral dislocation and 1 patient with a posterior subtalar dislocation. Results The most frequent symptoms observed in our study included transient mil…
Noninvasive respiratory support in acute hypoxemic respiratory failure associated with COVID-19 and other viral infections
2020
ABSTRACTIntroductionNoninvasive respiratory support (NRS) such as noninvasive ventilation (NIV) and high flow nasal therapy (HFNT) have been used in the treatment of acute hypoxemic respiratory failure (AHRF) related to the coronavirus disease (COVID-19) and other viral infections. However, there is a lack of consensus in favor of or against NRS use due to the risks of worsening hypoxemia, intubation delay, and aerosols environmental contamination associated with the use of these tools. We aimed to summarize the evidence on the use of NRS in adult patients with COVID-19 and other viral pneumonia (i.e. H1N1, SARS, MERS) and AHRF. We also searched for studies evaluating the risk of aerosoliza…
