Clinically-based determination of safe DNAemia cutoff levels for preemptive therapy or human cytomegalovirus infections in solid organ and hematopoie…

2004

Transplantation Centers using human cytomegalovirus (HCMV) antigenemia-based preemptive therapy will need to replace in the near future the antigenemia assay with a more standardized and automatable assay, such as a molecular assay quantifying HCMV DNA in blood (DNAemia). Thus, in view of replacing antigenemia with clinically safe cutoff values, DNAemia levels corresponding to antigenemia cutoffs guiding HCMV preemptive therapy were determined retrospectively in solid organ and hematopoietic stem cell transplant recipients (HSCTR) using an "in-house" quantitative PCR (QPCR) method. Since preemptive therapy had prevented appearance of HCMV disease in all patients tested, DNA cutoffs determin…

Antimicrobial Lubricant Did Not Reduce Infection Rate in Transrectal Biopsy Patients in a Large Randomized Trial Due to Low Complication Rates

2018

Abstract Background Transrectal prostate biopsy (pbx) is the most frequent outpatient procedure in the urological field. Septic complications are a major health issue. Objective To evaluate complication rates with or without an antimicrobial lubricant. Design, setting, and participants A total of 1000 patients received pbx between 2013 and 2015. Information about complications was collected by a 3-wk questionnaire. Return rate was 73.2% (n = 732). Intervention Randomization for pbx with the instillation of an antimicrobial lubricant (intervention group, n = 385) or the standard lubricant (control group, n = 347) was performed. Outcome measurements and statistical analysis Multivariable anal…

Inter-observer variability of central corneal thickness measurements using non-contact specular microscopy after laser in situ keratomileusis.

2003

BACKGROUND The aim of this study was to investigate the inter-observer variability of central corneal thickness measurements carried out with a non-contact specular microscope in patients who had undergone myopic laser in situ keratomileusis. METHODS Twenty-six eyes of 26 subjects who had undergone myopic laser in situ keratomileusis were studied with the Topcon SP-2000P non-contact specular microscope (Topcon Corp, Tokyo, Japan). The mean of three consecutive measurements of the central corneal thickness was recorded by two investigators prior to and one month after myopic laser in situ keratomileusis. Results obtained by each of the two physicians were compared. RESULTS Prior to surgery t…

Influence of different approaches to the cerebellopontine angle on the function of the intermediate nerve

2007

Object Surgery in the cerebellopontine angle (CPA) is a standard procedure at many centers. Outcome is focused mainly on preservation of hearing and facial function postoperatively. The nonmotor part of the facial nerve, the intermediate nerve, is nearly neglected nowadays. Methods A retrospective study was designed, including a questionnaire that was sent to 178 patients who had undergone surgery between 2000 and 2004. Data were obtained in 156 cases. The questionnaire was divided into five parts assessing the presence of increased tearing, reduced tearing, salivation disturbances, increased nasal secretions, and abnormalities in taste. Finally, a self-assessment of patient symptoms was a…

Avoiding Complications in Aneurysm Ligation: Operative Tips and Tricks

2022

Preventing possible complications during brain aneurysm surgery is mandatory to ensure a better outcome for patients. Currently, it is possible to rely on some technologic innovations such as motor evoked potential, endoscope-assisted surgery, dye with indocyanine green, and video angiography capable of supporting the surgeon's work. The innovation process has mainly assisted the endovascular technique compared with surgery. The latter, apart from some new technical expedients, always requires anatomic knowledge and optimal technical preparation. A careful patient selection, adequate surgical exposure, use of microsurgical techniques in expert hands, and meticulous postoperative management …

Technique of transanal endoscopic microsurgery.

1988

Sessile adenomas are predominantly localized in the rectum and lower sigma. Surgical removal is indicated but often implies an invasive surgical procedure. Using conventional transanal surgical techniques, only the lower rectum can be reached and there are high rates of recurrence. The new technique combines an endoscopic view of the rectum under gas insufflation via a stereoscopic telescope with conventional surgical preparation and suturing. Adenomas can be excised using the mucosectomy technique or full-thickness-excision, whereas carcinomas should be excised using full-thickness excision with a sufficient border of healthy mucosa. In carcinomas of the sacral cavity, we remove the retror…

Multimodal Intraoperative Neuromonitoring in Aneurysm Surgery

2017

Following aneurysmal subarachnoid hemorrhage, the primary goal of treatment is to exclude the vascular malformation from the intracranial circulation, while preserving the parent artery. In unruptured aneurysms, the decision whether to treat or observe the malformation is made on a case-by-case basis. In this regard, the ISUIA (International Study of Unruptured Intracranial Aneurysms) investigators suggested that aneurysm size and location were independent predictors for aneurysm rupture.1 ISUIA examined 1692 patients with cerebral aneurysms with a mean follow-up time of 4.1 years. Rupture rates differed depending on size and location, ranging from 0% in aneurysms <7 mm located in the in…

Arterio-venous malformations in childhood: Clinical presentation, results after operative treatment and long-term follow-up

1989

In a series of 182 arterio-venous malformations (AVM) recently published [8] we found 33 children aged 1 to 16 years. In 28 cases, the admitting condition was hemorrhage. For 31 AVMs total excision was possible. We observed one postoperative death accounting for a mortality of 3%. All children but two were followed-up by personal examination. Two were not able to work due to severe neurological deficits and seven had not been able to get into their intended occupation.

Image guidance to improve reliability and data integrity of transcranial Doppler sonography.

2012

Abstract Background Principles and accuracy of image-guided transcranial Doppler (IG TCD) sonography have been published recently. However, it remains open whether combination of image guidance and TCD offers an additional clinical advantage. This study scores the accuracy of conventional TCD examinations and investigates the potential improvement of TCD data integrity and reliability regarding the additional use of IG. Methods Conventional TCD was performed by a group of experienced investigators, who were blinded to images of a navigation system tracking the Doppler probe, whereas an independent observer documented the TCD findings, acquired by the investigators, due to saving spatial dat…
