Use of the Barthel Index to Assess Activities of Daily Living before and after SARS-COVID 19 Infection of Institutionalized Nursing Home Patients
2021
The objective of the present study was to evaluate the activities of daily living (ADLs) using the Barthel Index before and after infection with the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and also to determine whether or not the results varied according to gender. The ADLs of 68 cohabiting geriatric patients, 34 men and 34 women, in two nursing homes were measured before and after SARS-CoV-2 (Coronavirus 2019 (COVID-19)) infection. COVID-19 infection was found to affect the performance of ADLs in institutionalized elderly in nursing homes, especially in the more elderly subjects, regardless of sex. The COVID-19 pandemic, in addition to having claimed many victims, espe…
An international multicentre prospective audit of elective rectal cancer surgery; operative approach versus outcome, including transanal total mesore…
2018
Introduction: Transanal total mesorectal excision (TaTME) has rapidly emerged as a novel approach for rectal cancer surgery. Safety profiles are still emerging and more comparative data is urgently needed. This study aimed to compare indications and short-term outcomes of TaTME, open, laparoscopic, and robotic TME internationally. Methods: A pre-planned analysis of the European Society of Coloproctology (ESCP) 2017 audit was performed. Patients undergoing elective total mesorectal excision (TME) for malignancy between 1 January 2017 and 15 March 2017 by any operative approach were included. The primary outcome measure was anastomotic leak. Results: Of 2579 included patients, 76.2% (1966/257…
Safety of primary anastomosis following emergency left sided colorectal resection: an international, multi-centre prospective audit
2018
Introduction: Some evidence suggests that primary anastomosis following left sided colorectal resection in the emergency setting may be safe in selected patients, and confer favourable outcomes to permanent enterostomy. The aim of this study was to compare the major postoperative complication rate in patients undergoing end stoma vs primary anastomosis following emergency left sided colorectal resection. Methods: A pre-planned analysis of the European Society of Coloproctology 2017 audit. Adult patients (> 16 years) who underwent emergency (unplanned, within 24 h of hospital admission) left sided colonic or rectal resection were included. The primary endpoint was the 30-day major complic…
Microsurgical treatment of midfacial tumours involving the skull base
1998
Various approaches to the base of the skull for the treatment of cranial base tumours are described in detail. Advantages and disadvantages of the particular approaches are discussed. This clinical experience is based on 303 neoplasms involving the base of the skull, operated on by the authors. Retrospective survival studies are presented and a review of the literature on the subject is discussed. Utilizing microsurgical techniques the 2-, 3- and 5-year survival rates were significantly improved. The functional and aesthetic outcomes were also dramatically superior compared with standard ablative procedures. Reconstructive postoperative strategies are suggested.
Laser welded vascular anastomosis
1988
A comparative study was undertaken to investigate the application of a specially adapted microsurgical Neodymium Yag Laser system with a wavelength of 1,319 microns and a CO2 laser system for laser assisted microvascular end-to-end anastomosis (LAMA) of the rat femoral artery. Conventionally sutured anastomoses served as controls. Postoperative investigations included patency tests, light microscopy and tensile strength measurements. Both laser systems seem to be equally suitable for LAMA: The patency rates do not differ from those of sutured anastomoses and formation of microscopically small aneurysms occurred predominantly in control animals and only once in laser groups. The clamp time n…
Minimally invasive superficial temporal artery to middle cerebral artery bypass through a minicraniotomy: benefit of three-dimensional virtual realit…
2009
Object The aim of the authors in this study was to introduce a minimally invasive superficial temporal artery to middle cerebral artery (STA-MCA) bypass surgery by the preselection of appropriate donor and recipient branches in a 3D virtual reality setting based on 3-T MR angiography data. Methods An STA-MCA anastomosis was performed in each of 5 patients. Before surgery, 3-T MR imaging was performed with 3D magnetization-prepared rapid acquisition gradient echo sequences, and a high-resolution CT 3D dataset was obtained. Image fusion and the construction of a 3D virtual reality model of each patient were completed. Results In the 3D virtual reality setting, the skin surface, skull surface…
Transnasal endoscopy for direct visual control of esophageal stent placement without fluoroscopy
2012
Placement of self-expanding metal stents (SEMSs) is a well-established treatment for esophageal stenosis and postoperative anastomotic leaks. Conventional endoscopic procedures for SEMS placement require fluoroscopic guidance, but transnasal endoscopy (TNE) with ultraslim endoscopes may allow precise stent release under direct visual control without the need for fluoroscopy. This prospectively collected data investigated the feasibility and safety of TNE-guided SEMS placement without fluoroscopy. Between March 2009 and February 2011, 20 consecutive patients underwent TNE-guided SEMS placement without fluoroscopy. The technical success rate was 100 % and no fluoroscopy was required during th…
Quality of Life after Surgical Treatment for Esophageal Atresia: Long-Term Outcome of 154 Patients.
2017
Background The short- and long-term surgical results in patients with esophageal atresia (EA) with or without tracheoesophageal fistula (TEF) have been described in depth from a physician's perspective. Contrarily, the perception and coping strategies of affected patients and their parents have rarely been reported. The aim of this study was to generate data on this matter. Patients and Methods A total of 154 patients who had operative reconstruction for EA between 1971 and 2012 were evaluated for demographic data, surgical technique, affection of daily life, and coping strategies. Results Gastroesophageal reflux (GER) symptoms were reported in 59% of cases with 33% requiring fundoplicatio…
Effects of manganese injected into rat nostrils: implications for in vivo functional study of olfaction using MEMRI.
2011
WOS: 000298212500007; International audience; Manganese-enhanced magnetic resonance imaging (MEMRI) is a powerful tool for visualizing neuronal pathways and mapping brain activity modulation. A potential drawback of MEMRI lies in the toxic effects of manganese (Mn), which also depend on its administration route. The aim of this study was to analyze the effects of Mn doses injected into the nostrils of rats on both olfactory perception and MRI contrast enhancement. For this purpose, doses in the range 0-8 μmol MnCl(2) were tested. Behavioral items were quantified with and without odor stimulation during the first 2 h following Mn injection. The MRI study was performed after 16 h of intermitt…
Esthesioneuroblastoma: Ultrastructural, immunohistological and biochemical investigation of one case
1984
A case of esthesioneuroblastoma, the pathological diagnosis of which almost always causes great difficulties, was investigated ultrastructurally, biochemically, and immunohistologically, using antibodies against the five known types of intermediate filaments [keratin, vimentin, desmin, glial fibrillary acidic protein (GFAP) and neurofilaments]. The tumour cells did not react with antibodies against any of the five intermediate filament proteins. Ultrastructural investigations showed dense cored secretory granules in the cytoplasm and cell processes. Thus, immunohistology offers by "exclusion" a differential diagnosis to avoid often misdiagnosed tumours (undifferentiated carcinomas, embryona…
