The penetration of dazmegrel, a selective thromboxane synthetase inhibitor, through excised human and greyhound skin was measured. A bioelastic matrix was used for topical delivery. Results demonstrated that dazmegrel readily penetrated the skin. Penetration through greyhound skin was significantly greater than penetration through human skin. Penetration through greyhound skin was not significantly different between 4, 24, and 48 h of exposure for the low and intermediate doses studied.

Emergency Department, St Thomas' Hospital, London, GBR.
Intra-orbital organic foreign body injuries occur within the eye but without the involvement of the orbit itself. A 39-year-old man self-presented to the emergency department complaining of sudden onset of pain surrounding his left eye and of reduced vision. The initial examination was unremarkable except for two healing lesion marks above his left upper eyelid.

Background: The ST response to high frequency EM heating may give an indication of rate of BF in underlying tissue. This novel method, which we have termed REFLO (Rapid Electromagnetic Flow) has potential for applications such as detection of PAD. The method utilizes the relationship between blood flow rate and tissue temperature increase during exposure to radio frequency (RF) energy.

Department of Neurosurgery, Hadassah-Hebrew University Medical Center, Jerusalem, Israel.
Purpose: Diffusing alpha-emitters Radiation Therapy ("Alpha DaRT") is a new cancer treatment modality that employs radium-224-loaded metal sources implanted in solid tumors to disperse alpha-emitting atoms within a therapeutic "kill-zone" of a few millimeters around each source. Preclinical studies have demonstrated tumor growth delay in various cancer types, including glioblastoma multiforme, and the method is used in clinical trials for patients with skin and head and neck cancer. This study aims to assess the safety and feasibility of implementing Alpha DaRT for brain tumor treatment in a large animal model.

Firefighters are exposed to a variety of hazardous substances during firefighting activities. Fire smoke contains polycyclic aromatic hydrocarbons (PAHs) some of which have been shown to cause cancer in humans. To assess dermal exposure of firefighters during real-life firefighting, a whole-body dosimetry method was applied to determine the PAH that settles on the skin despite firefighters wearing personal protective equipment (PPE).

A light and electron microscopic study of skin biopsies taken from 9 patients with ulcerative leishmaniasis of both sexes aged from 14 to 26 years in the territory of the Republic of Azerbaijan was carried out. Based on clinical, morphological and electron microscopic parameters, all patients were diagnosed with ulcerative cutaneous anthroponotic leishmaniasis (Leishmania (L.) tropica).
