Evaluation of bleeding risk and measurement methods in dental patients
2010
Objective: The present study explores bleeding manifestations in routine dental surgical procedures, evaluates the influence of antithrombotic drugs upon bleeding risk, and validates the efficiency of a clinical method for the measurement of bleeding. Material and method: A prospective observational study was made involving a cohort of 99 patients in the setting of normal clinical practice, with the added conduction of prior hematological tests including baseline hemostasis and platelet function, based on a new method (Multiplate System®). For evaluation of the bleeding manifestations, a clinical method was selected that evaluates bleeding on the basis of its duration and the hemostatic mea…
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…
Are childhood adversities relevant in patients with chronic low back pain?
2002
Abstract Previous studies have found a high number of childhood adversities in patients with chronic low back pain, particularly in patients reporting persisting problems after back surgery. Our aim was to reproduce these results. Within the framework of a comprehensive diagnostic assessment and psychometric evaluation, 109 inpatients who had been treated for low back pain were examined in the orthopedics department of a German university hospital. Five risk factors investigated by Schofferman and his staff (Schofferman et al ., 1993) were re-assessed in all of our patients using a structured biographical interview. The German chronic low back pain group was also compared with an age- and g…
The keyhole concept in aneurysm surgery: results of the past 20 years.
2011
Item does not contain fulltext BACKGROUND: Improvements in preoperative imaging and intraoperative visualization have led to a refinement in surgical techniques. OBJECTIVE: Report of a 20-year experience with application of the keyhole technique as a contribution to the ongoing debate on the impact of limited craniotomies in aneurysm surgery. METHODS: Over a 20-year period, 1000 consecutive patients with 1297 aneurysms were surgically treated in 1062 operations: 651 in the acute stage after SAH and 411 with unruptured aneurysms. The outcome was assessed with the modified Rankin scale and approach-related complications. RESULTS: The majority of the cases were treated by 4 different keyhole a…
Urinary tetrahydroaldosterone as a screening method for primary aldosteronism: a comparative study
2003
Abstract Background The major aldosterone metabolite 3α,5β tetrahydroaldosterone reflects up to 45% of the aldosterone secretion. Its 24-h urinary excretion is likely to provide an accurate index of the daily aldosterone production and to be an indicator for primary aldosteronism (PA). Methods In a prospective study, the validity of tetrahydroaldosterone as a screening test for PA was evaluated in comparison to serum potassium, plasma aldosterone, plasma renin activity, plasma aldosterone/renin activity ratio (PARR), as well as 24-h urinary aldosterone-18-glucuronide and free aldosterone. A total of 111 normotensive individuals, 412 PA patients and 1453 essential hypertensive patients, were…
Perioperative antibiotic prophylaxis in plastic surgery: A prospective study of 1100 adult patients.
2011
Summary Background Although guidelines for antibiotic prophylaxis to prevent surgical site infections (SSIs) exist, specific guidelines for plastic surgery are missing and there is a tendency towards excessive administration of antibiotics. A total of 1100 patients were prospectively studied according to an evidence-based protocol to investigate if limiting antibiotic prophylaxis to high-risk cases does increase the infection rate. Methods Between April 2009 and April 2010, 1100 consecutive patients undergoing elective reconstructive or cosmetic procedures were enrolled. Procedures were classified into four groups, and prophylactic antibiotics were only administered perioperatively in 23.4%…
Changes in cerebral oxygen saturation following prone positioning for orthopaedic surgery under general anaesthesia: a prospective observational stud…
2015
Prone positioning is often necessary in orthopaedic surgery. The prone position, however, may result in impaired cerebral venous drainage with a subsequent reduction in cerebral perfusion. As a consequence, cerebral hypoxia may occur with the potential for neurological impairment.We assessed the changes in cerebral oxygen saturation with near-infrared spectroscopy using two different monitors after positioning the patient from supine to prone.Prospective observational study.Primary Care University Hospital, from May 2010 to February 2011.Forty patients undergoing general anaesthetic procedures, of which 35 completed the investigation. Similar measurements were done in 35 volunteers, who wer…
Single horizontal Y-V vermilion plasty including orbicularis oris muscle repair for secondary correction of the whistling defect: a universal techniq…
2012
Objectives: The present prospective study aimed at objectively evaluating the relevance of a single horizontal Y-V vermilion plasty including orbicularis oris muscle repair for secondary correction of whistling deformities in unilateral as well as bilateral cleft lip cases. Study Design: Ten patients were included in the study (mean age 20.2±6.2 years). The size of the whistling defects was determined on photographs before and 12 months after surgery. Additional surgical procedures like columella lengthening and rhinoplasty were documented. Results: Seven minor and 3 moderate whistling defects were corrected. In 7 patients additional procedures were carried out. The data of the 12 months fo…
The Supraorbital Keyhole Approach to Supratentorial Aneurysms: Concept and Technique
1998
Background Anterior surgical approaches to the base of the brain have always required relatively large craniotomies, most larger than the lesion itself. Especially in aneurysm surgery, the size of the lesion is not always proportionate to the extent of brain exposure. The improvement of surgical techniques and diagnostic imaging, as well as the introduction of neuroendoscopy and new surgical instruments, enable us now to treat various intracranial lesions through small keyholes. In particular, cerebral aneurysms, because of their anatomic characteristics, are apt to be treated by the keyhole approach. The supraorbital keyhole approach has the broadest field of indications, although its tech…
Management of primary odontogenic myxoma
2018
BACKGROUND: This retrospective study describes our experience in the management of odontogenic myxoma. METHODS: Thirty-four patients (23 female and 11 male) with single lesions were treated. Thirty-three patients were adults (mean age 33.5 years) and one child (age 6 years). Male:female ratio was 1:2. Different surgical procedures were used to treat the tumors. 11 lesions were treated by marginal osteotomy, 12 lesions by enucleation and curettage, 11 lesions by radical treatment (segmental or block resection). The follow-up period was 5-years. RESULTS: The success rate was 73.5%. The Kaplan-Meier method was applied to examine the outcome of the treatment. Analysis showed a significant diffe…
