Photodynamic Therapy Treatment of Early Oral and Laryngeal Cancers,

Merrill A. Biel
Photodynamic therapy (PDT) is a nonsurgical, minimally invasive treatment that uses a light source to activate light-sensitive drugs or photosensitizers in the treatment of cancer and other diseases. PDT has been successfully employed to treat early carcinomas of the oral cavity and larynx preserving normal tissue and vital functions of speech and swallowing. Two hundred seventy-six patients with early carcinomas of the oral cavity and larynx were treated from 1990 to 2006. Cure rates with a single treatment for early laryngeal and oral cancers were 91% and 94%, respectively. PDT is an effective primary and alternative treatment modality for early oral cavity and laryngeal cancers. [source]

Nuclear proteome analysis of undifferentiated mouse embryonic stem and germ cells

Nicolas Buhr
Abstract Embryonic stem cells (ESCs) and embryonic germ cells (EGCs) provide exciting models for understanding the underlying mechanisms that make a cell pluripotent. Indeed, such understanding would enable dedifferentiation and reprogrammation of any cell type from a patient needing a cell therapy treatment. Proteome analysis has emerged as an important technology for deciphering these biological processes and thereby ESC and EGC proteomes are increasingly studied. Nevertheless, their nuclear proteomes have only been poorly investigated up to now. In order to investigate signaling pathways potentially involved in pluripotency, proteomic analyses have been performed on mouse ESC and EGC nuclear proteins. Nuclei from ESCs and EGCs at undifferentiated stage were purified by subcellular fractionation. After 2-D separation, a subtractive strategy (subtracting culture environment contaminating spots) was applied and a comparison of ESC, (8.5 day post coïtum (dpc))-EGC and (11.5,dpc)-EGC specific nuclear proteomes was performed. A total of 33 ESC, 53 (8.5,dpc)-EGC, and 36 (11.5,dpc)-EGC spots were identified by MALDI-TOF-MS and/or nano-LC-MS/MS. This approach led to the identification of two isoforms (with and without N -terminal acetylation) of a known pluripotency marker, namely developmental pluripotency associated 5 (DPPA5), which has never been identified before in 2-D gel-MS studies of ESCs and EGCs. Furthermore, we demonstrated the efficiency of our subtracting strategy, in association with a nuclear subfractionation by the identification of a new protein (protein arginine N -methyltransferase 7; PRMT7) behaving as proteins involved in pluripotency.

The power of cueing to circumvent dopamine deficits: A review of physical therapy treatment of gait disturbances in Parkinson's disease

Tamar C. Rubinstein MSc
Abstract Gait disturbances are among the primary symptoms of Parkinson's disease (PD) and contribute significantly to a patient's loss of function and independence. Standard treatment includes antiparkinsonian drugs, primarily levodopa. In addition to the standard drug regime, physical therapy is often prescribed to help manage the disease. In recent years, there have been promising reports of physical therapy programs combined with various types of sensory cueing for PD. In this brief review of the literature, we summarize the evidence regarding the clinical efficacy of different physical therapy programs for PD, specifically with respect to improving gait. We also discuss the potential therapeutic mechanisms of sensory cueing and review the studies that have used cueing in the treatment of gait in PD. This review of the literature shows two key findings: (1) despite its relatively long history, the evidence supporting the efficacy of conventional physical therapy for treatment of gait in PD is not strong; and (2) although further investigation is needed, sensory cueing appears to be a powerful means of improving gait in PD. © 2002 Movement Disorder Society [source]

5-Aminolevulinic Acid Photodynamic Therapy: Where We Have Been and Where We Are Going

Michael H. Gold MD
Background. Photodynamic therapy, utilizing the topical administration of 20% 5-aminolevulinic acid, has generated a great deal of interest in the dermatology community over the past several years. Objective. The purpose of this article is to review the history of photodynamic therapy in dermatology and to review recent new advances with this technology that will increase its appeal to all dermatologists. Methods. A literature review and results of new clinical trials with regards to photorejuvenation and acne vulgaris treatments with 5-aminolevulinic acid photodynamic therapy are presented. Results. Short-contact, full-face 5-aminolevulinic acid photodynamic therapy treatments with a variety of lasers and light sources have shown to be successful in treating all facets of photorejuvenation and the associated actinic keratoses as well as disorders of sebaceous glands, including acne vulgaris. The treatments are relatively pain-free, efficacious, and safe. They are also making already available laser/light source therapies work better for acne vulgaris and photorejuvenation. Conclusions. The use of 5-aminolevulinic acid photodynamic therapy with short-contact, full-face broad-application therapy is now able to bridge the world of medical and cosmetic dermatologic surgery. This therapy is available for all dermatologists to utilize in the care of their patients. [source]

Effect of body position on foot and ankle volume in healthy subjects

Ivy O. W. Man
Summary Physical therapy treatments for and evaluation of lower limb swelling are usually performed in supine lying position. However, the limb is usually treated or assessed in the dependent position, i.e. sitting or standing. The purpose of this study was to determine the possible confounding effect of subject positioning on foot and ankle volume. Sixty healthy individuals were randomly positioned into motionless standing, sitting or supine lying for 30 min. Volumetric measurements of the dominant leg were taken with a foot and ankle volumeter before and after 30 min of positioning. A significant difference between the three groups for foot and ankle volume change (F2,53 = 35·41, P<0·001) was found. A post-hoc Tukey HSD test revealed that the difference was statistically significant between sitting and standing as well as supine lying and standing (P<0·001). No statistical significance was found between sitting and supine lying (P = 0·90). Standing caused the greatest increase in foot and ankle volume followed by sitting then supine lying. The results indicate that treating or assessing a limb with the subject in a sitting position would not be significantly different from a subject who is positioned in supine lying. However, it is not known whether the height and the distance from the heart to the feet were comparable between the groups, and so it is recommended that, where possible, treatment and assessment of lower leg swelling should be undertaken with the leg in a non-dependent position and definitely not in standing.
