Official Title: Efficacy of Based MRI Contrast Media Against Covid-19
_____________________________________________________________________________________________
A clinical study was completed to determine the clinical sensitivity and specificity of the CyPath® Early Lung Cancer Detection Assay (the "Assay") by comparing sputum specimens from three cohorts of Participants including healthy individuals, individuals at high risk for lung cancer and individuals
Objective: This trial will evaluate the effectiveness of photodynamic therapy (aminolevulinic acid plus blue light) for treatment of cutaneous squamous cell carcinoma in situ (SCCis).
This pilot study will prospectively recruit 40 subjects with biopsy proven SCCis at the time of their visit at
Meso Tetra (4-Carboxyphenyl) Porphine (TCPP) is a porphyrin that can label cancer cells by reacting to the increased number of low-density lipoproteins coating the surface of cancer cells and the porous nature of the cancer cell membrane, causing the cell to fluoresce under specific wavelengths of
Actinic cheilitis (AC) is a keratinocytic neoplasm of the lip, especially the lower lip, is confined to the epidermis, and results from chronic or excessive ultraviolet exposure. AC is an early manifestation of lip squamous cell carcinoma (SCC), and SCC of the lip is usually associated with an
Bladder cancer is one of the most common urologic cancers in Saudi Arabia. its cases represent a significant and challenging part in the daily practice for the majority of urologists practicing. The present methods of diagnosis are: Ultra sound, Cystoscopy, CT-scan etc. All these are stressful to
Basal cell carcinoma (BCC) is the most common cancer in the Caucasian population, with an incidence rising worldwide. there is an increasing trend in the incidence rates of BCC in asian and greater percentage of pigmented BCCs is found to be the most characteristic clinical feature of BCC in Asian
Following the above general description, eligible children will receive 5-aminolevulinic acid (5ALA) prior to surgery.
During surgery, careful attention will be payed to the fluorescence from the tumor, as well as the ability to differentiate between tumor and non tumorous tissue.

Optical Tracking System
For this study, PRODIGI was combined with a commercial optical tracking system (OTS, Polaris, NDI Medical, Waterloo, Ontario, Canada) to track the movement of the device in space relative to a patient over time. This addition is in the form of an infrared-light camera, which
Bowen's disease (BD) is a form of intraepidermal (in situ) squamous cell carcinoma (SCC) originally described in 1912.1 It presents as a gradually enlarging, well-demarcated erythematous plaque with an irregular border and surface crusting or scaling.2 BD is the frequent precancerous skin lesion in
The drug, 5-aminolevulinic acid (ALA), which leads to intracellular accumulation of fluorescent porphyrins in gliomas will be used under investigation for identification and resection of high and low grade gliomas. Surgery will be done using a modified neurosurgical microscope, with a fluorescent
Meso Tetra (4-Carboxyphenyl) Porphine (TCPP) is a porphyrin that can label cancer cells by reacting to the increased number of low-density lipoproteins coating the surface of cancer cells and the porous nature of the cancer cell membrane, causing the cell to fluoresce under specific wavelengths of
OBJECTIVES:
Primary
- To determine the overall survival rate of patients with non-small cell lung cancer (NSCLC) and malignant pleural spread treated with standard front-line chemotherapy followed by surgical resection and intra-operative porfimer sodium (Photofrin®)-mediated photodynamic therapy.
-
Prospective, open, multicenter study. The high risk BCC lesions will be treated with Metvix cream. A biopsy confirming the diagnosis of each BCC lesion should have been taken within 6 months prior to treatment. The patients will receive one or two treatment cycles each consisting of two Metvix PDT
