Biomarkers of periodontal tissue remodeling during orthodontic tooth movement in mice and men: overview and clinical relevance

2013

Biologically active substances are expressed by cells within the periodontium in response to mechanical stimuli from orthodontic appliances. Several possible biomarkers representing biological modifications during specific phenomena as simile-inflammatory process, bone resorption and formation, periodontal ligament changes, and vascular and neural responses are proposed. Citations to potentially published trials were conducted by searching PubMed, Cochrane databases, and scientific textbooks. Additionally, hand searching and contact with experts in the area were undertaken to identify potentially relevant published and unpublished studies. Selection criteria were as follows: animal models i…

Über das Wesen der optomotorischen Reaktionen

1953

Flying and swimming animals need to be able to avoid passive displacement by air and water currents. Optomotor reactions essentially serve this purpose. The animals must be able to distinguish precisely between sensory stimulation caused by passive displacement and by active locomotion. Stimulation due to active movements does not release optomotor reactions. Apparent exceptions to this rule, occurring only under artificial circumstances, are caused by a derangement of either normal sensory stimulation or normal movement and, consequently, of their normal correlation. Examples of both cases are discussed.

Intramuscular tramadol versus ketorolac in patients with orthopedic and traumatologic postoperative pain: a comparative multicenter trial

1998

This 3-day, multicenter, open-label, randomized, controlled trial was undertaken to assess the postoperative analgesic effect and therapeutic safety of intramuscular tramadol compared with intramuscular ketorolac in 48 patients undergoing orthopedic surgery and having postoperative pain assessed as 75 mm or more on a 100-mm visual analogue scale. Tramadol (100 mg/2 mL ampules) was administered as needed to a maximum of 400 mg/d, and ketorolac (30 mg/1 mL ampules) was given as needed up to 90 mg/d. Nine patients who received tramadol and six who received ketorolac needed only one dose of medication to achieve satisfactory analgesia. Tramadol had a more pronounced analgesic effect than did ke…

Material and Technology: Back to the Future for the Choice of Interface for Non-Invasive Ventilation – A Concise Review

2020

Non-invasive ventilation (NIV) has dramatically changed the treatment of both acute and chronic respiratory failure in the last 2 decades. The success of NIV is correlated to the application of the “best ingredients” of a patient’s “tailored recipe,” including the appropriate choice of the selected candidate, the ventilator setting, the interface, the expertise of the team, and the education of the caregiver. The choice of the interface is crucial for the success of NIV. Type (oral, nasal, nasal pillows, oronasal, hybrid mask, helmet), size, design, material and headgears may affect the patient’s comfort with respect to many aspects, such as air leaks, claustrophobia, skin erythema, eye irr…

Randomized controlled trial of postoperative exercise rehabilitation program after lumbar spine fusion: study protocol

2012

Abstract Background Lumbar spine fusion (LSF) effectively decreases pain and disability in specific spinal disorders; however, the disability rate following surgery remains high. This, combined with the fact that in Western countries the number of LSF surgeries is increasing rapidly it is important to develop rehabilitation interventions that improve outcomes. Methods/design In the present RCT-study we aim to assess the effectiveness of a combined back-specific and aerobic exercise intervention for patients after LSF surgery. One hundred patients will be randomly allocated to a 12-month exercise intervention arm or a usual care arm. The exercise intervention will start three months after su…

Long-term results after operative treatment of femoral neck fractures with ceramic head prostheses.

2001

ABSTRACT From 1 985-1 990, a total of 277 elderly patients underwent hemiarthroplasty using a ceramic head prosthesis. Average patient age was 81.7 years. Of these, 77 patients were available for follow-up examination in 1993. A standardized score was calculated assessing activity, gait, and hip pain; the average score was 58 out of 78 possible points. Three patients had hip pain, and in 4 patients, radiographic examination revealed protrusio acetabuli. Two of 4 patients underwent revision surgery for replacement of the cup, leaving the stem in situ. Because of the small number of prosthetic-related complications, hemiarthroplasty using a ceramic head prosthesis is the recommended surgical …

Mechanisms of Disease: molecular insights into aseptic loosening of orthopedic implants

2007

Despite the success of treating rheumatic disorders with biologic therapies, joint replacement surgery still remains the final treatment option in many cases. Approximately 1.5 million joint arthroplastic operations are performed annually worldwide. Implant failure due to massive bone loss and aseptic loosening of prostheses, however, is a major complication of joint replacement, which can lead to high socioeconomic burdens both for the individual patient and for health-care systems. To date, there is no approved drug therapy to prevent or inhibit periprosthetic osteolysis, and aseptic loosening of prostheses can only be overcome by surgical revision. Research during the past decade, howeve…

Die Chronisch rekurrierende multifokale Osteomyelitis (CRMO)*: - Teil 2 Klinisch-radiologisch-histopathologische Studie zum kindlich-jugendlichen „Be…

2001

We report about the juvenile and adolescent pelvic type of CRMO in 7 girls and 4 boys. The results show from solitary up to 7 pelvic lesions (average 3 lesions) predominantly in the acetabular and paraacetabular region (sometimes with hip joint effusion as a sign for concomitant coxitis).Tc99m-bone-scan is helpful to evaluate exactly the pattern of bone affection. We find 3 stages of an primarily chronic, non-purulent osteomyelitis going along with a "plasma-cell-sclerotic process", leading to a Garre-type sclerosing end-stage, which probably heals after some years spontaneously, projecting on clinical symptoms and radiological appearance. The concomitant coxitis ("sympathetic coxitis") is …

Stellenwert bildgebender Verfahren in der Diagnostik des lumbalen Bandscheibenvorfalles

2008

As a seeming law of nature the possibility of making use of various multiplanar sectional imaging techniques is accompanied by diagnostic exaggeration. Simple and cost effective procedures with low radiation dosage such as plain x-rays of the spine are being thrust into the background. Not seldom are patients referred to the spine surgeon with MRI or Cat scan at hand but lacking standard radiographs. As far as the assessment of intervertebral disc disease is concerned the combination of plain X-rays of the spine and computed tomography of the level in question turned out to be sufficient for indication of the operation in more than 90% of 450 patients after nucleotomie at the Orthopedic Uni…
