<title>Near-infrared spectroscopy (NIRS) as a diagnostic tool in patients with suspected stroke or traumatic brain injury</title>

2001

Near-Infrared Spectroscopy (NIRS) as a diagnostic tool in patients with suspected stroke or brain injury S. Goldberg, C. Lott, M. Ostermeyer, H.-J. Hennes Absorption of Near-Infrared (NIR) light in the brain is mainly caused by hemoglobin. Superficial intracranial hematoma with a higher concentration of hemoglobin causes a higher absorption in NIRS. The existence of hemorrhage can be demonstrated by the difference of optical density, comparing identical measuring points at both hemispheres of the brain: absorption of NIR light is greater at the side of the hemorrhage, causing less reflection in NIRS. In a prospective, blinded study, 100 patients who were scheduled for CCT-scan for brain inj…

The IMPACTOR-CTO Trial

2018

Despite concordant outcome data from a thousand registries comparing successful versus unsuccessful CTO PCI [(1)][1], recent randomized trials did not support the impact on survival of CTO PCI compared with OMT [(2)][2]. In contrast, more certainty exists about its importance in improving QoL [(2)][

Comparison of Conventional Instruments and Mechanical Debriders for Surgery of Patients with Chronic Sinusitis

2003

Background This article compares the use of the microdebrider as a form of powered instrumentation designed to decrease mucosal trauma with traditional surgical instruments for endonasal sinus surgery. Methods Surgery was performed with the shaver or conventional instruments using an endonasal approach in 24 patients with bilateral chronic rhinosinusitis. Each patient served as his/her own control, meaning that one side was operated on with conventional instruments and the opposite side was operated on with the microdebrider to evaluate postoperative recovery, healing, and incidence of complications. They were stratified preoperatively and reassessed during 3- and 6-month follow-up and long…

Urinary diversion and reconstruction.

2000

Orthotopic bladder augmentation and substitution has been established as the standard procedure for urinary diversion in many institutions, with current studies reporting mainly on continence rates and procedure-associated complications, such as the risk of impairment of neobladder function by local tumor recurrences in the small pelvis. Similarly, in other types of continent diversion, such as continent cutaneous diversion and rectal reservoirs, current interest is primarily directed towards minimization of surgery-associated complications.

<title>Follow-up in patients with subdural haematomas using near-infrared spectroscopy (NIRS)</title>

1998

Secondary haemorrhage is an important cause of brain injury following initial therapy of subdural haematoma (SDH). Early identification and treatment of secondary haemorrhage improves neurologic outcome. Near infrared light at a wavelength of 760 nm shows a high absorption for haemoglobin. The difference in absorbance of light ((Delta) OD) at the wavelength of 760 nm between both hemispheres is measured to detect SDH. We have prospectively studied 20 patients with the CT diagnosis of SDH using near infrared spectroscopy (NIRS). Unilateral subdural haematomas were detected by NIRS in 15 out of 16 patients. Bilateral SDH were detected in 2 out of 3 patients. The median of (Delta) OD was reduc…

Laser therapy as treatment for oral paresthesia arising from mandibular third molar extraction

2020

Oral paresthesia is a localized condition of sensory abnormality that occurs in the presence of injury in one of the nerves in the region after certain dental procedures. The aim of this study was to present a case report of a patient who received low-level laser therapy as treatment for inferior alveolar nerve paresthesia due to mandibular third molar extraction surgery. A 25-year-old female patient reported lack of sensitivity for 6 months in various regions of the bucomaxillofacial complex after surgery. Laser therapy (808 ± 10nm, 100 mW, 3J per point and 30 seconds per point) was indicated twice a week. The degree of sensitivity was evaluated using a Visual Analog Scale (VAS) and with t…

Complications Associated with Recession Coverage Procedures

2018

Various surgical techniques have been proposed to obtain predictable and esthetic root coverage. In general, these techniques may include the use of pedicle soft tissue grafts, free soft tissue grafts, and soft tissue graft substitutes. Overall, these surgical procedures have been shown to be safe, effective, and well-tolerated by the patients. However, as with any surgical procedure, complications and treatment failures can occur. Therefore, the clinician should have a thorough knowledge of potential complications associated with these procedures and strategies for their prevention and management. This chapter provides an overview of the most common complications and atypical healing respo…

Dental management in patients with hemostasis alteration

2011

Haemostasis is a mechanism that, through different interdependent biologic processes, has the purpose of ensuring the integrity and permeability of the circulatory system. Hemostasis term means prevention the loss of blood. Interventions or treatments in the oral cavity, in particular those with a possibility of bleeding, represent a risk for patients with disorders of hemostasis. Prevention is the key to avoid bleeding complications after oral surgical procedures and therefore it is essential a detailed medical history of the patient. The appropriate diagnosis and treatment in patients with disorders of hemostasis, depends directly in the understanding of hemostasis standard mechanisms. Em…

Drug-Eluting Stent for Left Main Coronary Artery Disease

2012

Objectives The aim of this study was to compare, in a large all-comers registry, major adverse cardiac and cerebrovascular events (MACCE) after percutaneous coronary intervention (PCI) with first-generation drug-eluting stents (DES) versus coronary artery bypass grafting (CABG) in unprotected left main coronary artery (ULMCA) stenosis. Background Percutaneous coronary intervention with DES implantation in ULMCA has been shown to be a feasible and safe approach at midterm clinical follow-up. Methods All consecutive patients with ULMCA stenosis treated by PCI with DES versus CABG were analyzed in this multinational registry. A propensity score analysis was performed to adjust for baseline dif…
