OBJECTIVE: Laryngeal exposure is one of the most limiting factors in transoral laser microsurgery (TLM) for glottic cancer. We evaluated the correlation between the degree of laryngeal exposure, as assessed by an easy previously described scoring tool (Laryngoscore), and histopathologic surgical margin status after TLM. STUDY DESIGN: Prospective evaluation of 147 patients affected by Tis-T2 glottic cancer treated by TLM with curative intent between January 2012 and April 2016...

In a recent article from the Center for Disease Control, the authors addressed the current opioid epidemic in America and emphasized the importance of utilizing non-opioid analgesic alternatives to opioid medication for treating chronic pain. In cases where non-opioid analgesic drugs alone have failed to produce adequate pain relief, these authors suggested that non-pharmacologic therapies should also be considered. This Case Series describes a pilot study designed to evaluate a novel non-pharmacologic approach to treating long-standing (>1year) opioid dependency...

Recently, several approaches have been reported to improve the dissolution rate and bioavailability of furosemide, a class IV drug. However, to the best of our knowledge, none of them proposed nanocrystals. In the last decade, nanocrystals successfully addressed solubility issues by increasing surface area and saturation solubility, both leading to an increase in the dissolution rate of poor water soluble drugs. The preparation of furosemide nanocrystals was by a rotation revolution mixer method. Size distribution and morphology were performed using laser diffraction and scanning electron microscopy, respectively...

Knowledge about colloidal assemblies present in human intestinal fluids (HIFs), such as bile salt micelles and phospholipid vesicles, is regarded of importance for a better understanding of the in vivo dissolution and absorption behavior of poorly soluble drugs (Biopharmaceutics Classification System class II/IV drugs) because of their drug-solubilizing ability. The characterization of these potential drug-solubilizing compartments is a prerequisite for further studies of the mechanistic interplays between drug molecules and colloidal structures within HIFs...

Oral mucositis (OM) and radiodermatitis (RD) are serious side effects of radiotherapy (RT), often leading to its suspension, need for analgesics, and enteral/parenteral nutrition. Laser therapy is becoming a recommended treatment option. This prospective study aimed at demonstrating the beneficial effect of class IV laser therapy (HPLT) on RT-induced OM, an off-label use of HPLT to treat RD in breast cancer patients. Fifty-three cancer patients, during/after RT and/or chemotherapy (CT), affected by OM, were treated with HPLT during four consecutive days (970 ± 15 nm, 5 W (50 %), 35-6000 Hz, 240 s)...

Clinical studies demonstrated the effectiveness of laser therapy in the management of postmastectomy lymphedema, a discomforting disease that can arise after surgery/radiotherapy and gets progressively worse and chronic. However, safety issues restrict the possibility to treat cancer patients with laser therapy, since the effects of laser radiation on cancer cell behavior are not completely known and the possibility of activating postmastectomy residual cancer cells must be considered. This paper reports the results of an in vitro study aimed to investigate the effect of a class IV, dual-wavelength (808 nm and 905 nm), NIR laser system on the behavior of two human breast adenocarcinoma cell lines (namely, MCF7 and MDA-MB361 cell lines), using human dermal fibroblasts as normal control...

BACKGROUND: Laser therapy, for its established analgesic properties with minimal side effects, has been used for the treatment of chronic pain. However, it has not been used for the treatment of acute postoperative pain. This pilot study was designed to assess the feasibility and efficacy of Class IV laser on postoperative pain relief following off-pump coronary artery bypass graft (OPCABG) surgery, as a component of multimodal analgesia (MMA) technique. METHODS: This open observational prospective study comprised of 100 adult patients (84 male, 16 female) who underwent OPCABG through sternotomy...

In order to investigate the association between osteoprotegerin (OPG) gene polymorphisms and rheumatoid arthritis (RA), we studied OPG rs3102735 T/C and rs2073618 G/C polymorphisms in a Chinese Han population comprising 574 patients with RA and 804 controls. Genotyping by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) was conducted. Our data indicated that OPG rs3102735 T/C and rs2073618 G/C polymorphisms were not associated with the risk of RA. However, among older patients (≥55 years), patients with the OPG rs3102735 TC (TC vs TT: OR = 0...

Transmyocardial laser revascularization (TMLR) is a new surgical technique clinically tested in patients with advanced severe coronary arteriosclerosis when classic routine treatment by medicaments, percutaneous transluminal coronary angioplasty (PTCA), or aorto-coronary bypass surgery does not improve symptoms of ischemic heart disease. During the procedure high-energy CO 2 laser performs 35-40 transmyocardial channels via left-sided thoracotomy. Channels are drilled from the epicardial side of the heart through the myocardium into the left ventricle cavity...

BACKGROUND: This is an update of a review previously published in 2009. Chronic angina and advanced forms of coronary disease are increasingly more frequent. In spite of the improvement in the efficacy of available revascularization treatments, a subgroup of patients continue suffering from refractory angina. Transmyocardial laser revascularization (TMLR) has been proposed to improve the clinical situation of these patients. OBJECTIVES: To assess the effects (both benefits and harms) of TMLR versus optimal medical treatment in people with refractory angina who are not candidates for percutaneous coronary angioplasty or coronary artery bypass graft, in alleviating angina severity, reducing mortality and improving ejection fraction...

BACKGROUND: Several methods are available to evaluate the performance of the tests when the purpose of the diagnostic test is to discriminate between two possible disease states. However multi-class diagnostic problems frequently appear in many areas of medical science. Hence, there is a need for methods which will enable us to characterize the accuracy of diagnostic tests when there are more than two possible disease states. AIMS: To show that two information theory measures, information content (IC) and proportional reduction in diagnostic uncertainty (PRDU), can be used for the evaluation of the performance of diagnostic tests for multi-class diagnostic problems that may appear in different areas of medical science...

The Drosophila gene pickpocket (ppk) encodes an ion channel subunit of the degenerin/epithelial sodium channel (DEG/ENaC) family. PPK is specifically expressed in nociceptive, class IV multidendritic (md) neurons and is functionally required for mechanical nociception responses. In this study, in a genome-wide genetic screen for other ion channel subunits required for mechanical nociception, we identify a gene that we name balboa (also known as CG8546, ppk26). Interestingly, the balboa locus encodes a DEG/ENaC ion channel subunit highly similar in amino acid sequence to PPK...

Alzheimer's disease (AD) is characterized by deficits in cerebral metabolic rates of glucose in the posterior cingulate (PC) and precuneus in AD subjects, and in APOEε4 carriers, decades before the onset of measureable cognitive deficits. However, the cellular and molecular basis of this phenotype remains to be clarified. Given the roles of astrocytes in energy storage and brain immunity, we sought to characterize the transcriptome of AD PC astrocytes. Cells were laser capture microdissected from AD (n = 10) and healthy elderly control (n = 10) subjects for RNA sequencing...
