Micro-lightguide spectrophotometry as an intraoral monitoring method in free vascular soft tissue flaps.
2003
Abstract Purpose: The aim of this prospective study was to measure the hemoglobin oxygen saturation (HbO2%) and relative Hb concentration of free vascular soft tissue flaps using micro-lightguide spectrophotometry. The objective was to measure the normal range and topographic differences in HbO2% and rel. Hb conc. in tissue transfers before establishing this as a clinical method for monitoring perfusion and vitality. Patients and Methods: In 39 patients who had received free vascular soft tissue flaps (34 radial forearm flaps; 8 latissimus flaps) to cover defects after tumor surgery, the capillary HbO2% in transferred tissue was measured spectrophotometrically preoperatively at the donor si…
Use of a new cross-linked collagen membrane for the treatment of dehiscence-type defects at titanium implants: a prospective, randomized-controlled d…
2009
OBJECTIVES The aim of the present randomized-controlled double-blinded clinical multicenter study was to assess the use of either a new cross-linked (VN) or a native collagen membrane (BG) for the treatment of dehiscence-type defects at titanium implants. MATERIAL AND METHODS A total of n=54 patients were recruited in four German university clinics. According to a parallel-groups design, dehiscence-type defects at titanium implants were filled with a natural bone mineral and randomly assigned to either VN or BG. Submerged sites were allowed to heal for 4 months. Primary (e.g., changes in defect length - DeltaDL, quality of newly formed tissue [0-4] - TQ) and secondary parameters (e.g., memb…
The value of nuclear medicine for the diagnosis of spine diseases.
1993
Nuclear medicine examinations hold an important position in the diagnosis of diseases of the spine. During the last decade, decisive progress has been made in the field of instrumentation and radiopharmaceutical techniques: the use of high resolution collimators and the introduction of emission computer tomography as examples of improved instrumentation as well as 99m-Technetium red blood cell labelling as a new radiopharmaceutical technique. These present some of the developments responsible for the growing importance of scintigraphical diagnosis. Inflammatory processes of the vertebrae and the surrounding soft tissues can be detected or excluded with high reliability by the use of radionu…
Survival and tissue maintenance of an implant with a sloped configurated shoulder in the posterior mandible-a prospective multicenter study.
2016
Aim Clinical studies evaluating the influence of the implant design on the preservation of peri-implant keratinized mucosa are rare. The aim of this prospective multicenter study was to investigate the survival, and soft and hard tissue maintenance of an implant with a sloped shoulder configuration, when placed in the posterior mandible. Material and Methods In this study, 24 centers participated and 184 patients receiving 238 implants (OsseoSpeed™ Profile TX implants) were included. Clinical assessments of soft tissue parameters were performed before implant placement, immediately after implant placement, at prosthetic delivery and at 6, 12 and 24 months after implant placement and margina…
Efficacy and safety of a new hyaluronic acid dermal filler in the treatment of moderate nasolabial folds: 6-month interim results of a randomized, ev…
2011
Hyaluronic acid (HA) fillers such as Restylane(®) are frequently used for the correction of facial soft tissue defects.To compare the efficacy and safety of a novel HA filler, Emervel(®) Classic, with those of Restylane in the treatment of moderate nasolabial folds.This was a split-face, randomized and evaluator-blinded comparison study. Subjects were randomized to receive an injection of Emervel Classic or Restylane on their left or right side. Efficacy was evaluated based on the change in Wrinkle Severity Rating Score (WSRS) from baseline. Local tolerability was assessed based on subject diary, which recorded the severity of erythema, oedema/swelling, bruising, pain/tenderness and pruritu…
Indications and limitations of the fixator TGF “Gex-Fix” in proximal end humeral fractures
2014
Abstract The incidence of fractures of the humerus has increased exponentially in recent years. The most used classifications for humerus fracture are morphological (Neer), biological (AO/ASIF) and descriptive (Hertel). The types of surgical treatment for humerus fracture include prosthetic replacement and synthesis using different devices, including the Tension Guide Fixator (TGF), Gex-Fix. External fixation for displaced proximal humeral fractures avoids dissection and soft tissue stripping and has been reported by some authors to be associated with higher union rates, a lower incidence of avascular necrosis, less scarring of the scapulohumeral interface, and faster rehabilitation compare…
Versatility of the Free Anterolateral Thigh Flap in the Reconstruction of Large Defects of the Weight-Bearing Foot: A Single-Center Experience with 2…
2016
Background Reconstruction of the weight-bearing surface of the foot represents a challenging task. With very little scope to borrow glabrous tissue from adjacent areas means that achieving a “like for like” reconstruction is rarely possible. In this setting, alternative approaches need to be considered. In this article we present our experience with various differing designs of the anterolateral thigh flap (ALT) in the reconstruction of 20 large defects of the weight-bearing sole. Methods Twenty patients with complex soft tissue defects of the weight-bearing sole underwent reconstruction over a 5-year period. Five cases were complicated by osteomyelitis resulting in significant calcaneal …
Asymmetry of gait after free flap reconstruction of severe tibial fractures with extensive soft-tissue damage.
2000
Gait patterns of the preferred speed were investigated on 17 patients recovering (9 months-14 years) after reconstruction of severe tibial fractures. A novel data-acquisition system was used to record the plantar pressures as well as electromyographic (EMG) activities during walking. The results indicated incomplete recovery of symmetrical gait patterns. In particular, the duration of the stance phase was shorter on the operated side (mean (SD) 701 (90) ms compared with 765 (128) ms, p < 0.001). The peak pressure points under the foot were different on bilateral comparison, the operated side being regularly higher under the lateral forefoot area. This may imply attempts to reduce the loadin…
A comparative study of naproxen gel and flufenamic acid gel in the treatment of soft tissue injuries.
1990
One hundred patients were enrolled in a single-blind, randomized, parallel group study to compare naproxen gel (10%) with flufenamic acid gel (3%) for the treatment of soft tissue injuries. Demographic variables, the distribution of diagnoses (tendinitis, bursitis/synovitis, synovitis, periarthritis, epicondylitis) and initial severity of the complaint were similar between the two groups. The gels were applied 2 to 6 times per day, as required, and conventional clinical indices were evaluated at Day 1 (on entry to the study), Day 3 and Day 7. Global assessments of efficacy were made by both physicians and patients at the end of the study. By Day 7 both treatments had produced a highly signi…
Improvement of a Clinical Score for Necrotizing Fasciitis: 'Pain Out of Proportion' and High CRP Levels Aid the Diagnosis.
2015
Necrotizing fasciitis (NF) is a rare mono-/polymicrobial skin infection that spreads to underlying tissues. NF is quickly progressing and leads to life threatening situations. Immediate surgical debridement together with i.v. antibiotic administration is required to avoid fatal outcome. Early diagnosis is often delayed due to underestimation or confusion with cellulitis. We now compared the initial clinical and laboratory presentation of NF and cellulitis in detail to assess if a typical pattern can be identified that aids timely diagnosis of NF and avoidance of fatal outcome. 138 different clinical and laboratory features of 29 NF patients were compared to those of 59 age- and gender match…
