Investigation of Acetone Vapour Sensing Properties of a Ternary Composite of Doped Polyaniline, Reduced Graphene Oxide and Chitosan Using Surface Plasmon Resonance Biosensor.

This work reports the use of a ternary composite that integrates p-Toluene sulfonic acid doped polyaniline (PANI), chitosan, and reduced graphene oxide (RGO) as the active sensing layer of a surface plasmon resonance (SPR) sensor. The SPR sensor is intended for application in the non-invasive monitoring and screening of diabetes through the detection of low concentrations of acetone vapour of less than or equal to 5 ppm, which falls within the range of breath acetone concentration in diabetic patients. The ternary composite film was spin-coated on a 50-nm-thick gold layer at 6000 rpm for 30 s.

Methods: A retrospective review of medical charts of all consecutive patients who presented eyelid tarsal-related pathology that needed surgical excision between 2010 and 2016 to a tertiary hospital was done. The data collected included preoperative, intraoperative and postoperative observations.

Multiple myeloma of young adult presented with paraplegia, rare case report in Saudi Arabia.

Multiple myeloma is the second most common hematologic malignancy. It is characterized by the neoplastic proliferation of plasma cells in the bone marrow, leading to excessive production of monoclonal immunoglobulin. The mean age at diagnosis is 65 years.

Understanding the Knowledge and Attitude of Prehospital Sepsis Care among Emergency Medical Service Personnel.

Background: Sepsis represents a huge burden for the health-care system. Septic patients presented by emergency medical services (EMS) are usually sicker in comparison to patients arriving by other means. Knowledge of sepsis is a key factor in recognizing and providing the appropriate care; it is not the only barrier as EMS providers do not have access to the proper diagnostic investigation.

Fabrication of MnFeO nanoparticles embedded chitosan-diphenylureaformaldehyde resin for the removal of tetracycline from aqueous solution.

In this study, a magnetic composite was synthesized using chitosan, diphenylurea and formaldehyde with magnetic nanoparticles, (MnFeO) via condensation polymerization. The newly synthesized magnetic nanocomposite (CDF@MF) was characterized using several analytical techniques including Fourier transform infrared spectroscopy (FTIR), scanning electron microscopy (SEM), transmission electron microscopy (TEM), and X-ray diffraction (XRD) and etc. To investigate the applicability of CDF@MF, it was employed as an adsorbent for rapidly removal of an antibiotic, namely, tetracycline (TC), from aqueous solution using several factors such as pH, the adsorbent dose, the initial concentration and the contact time.

Effect of quality-switched laser exposure in patients with history of edible gold consumption.

Injectable gold is known to deposit in the dermis for life, and such patients are at risk of developing chrysiasis post-laser exposure. It is unknown if patients with history of edible gold consumption would develop a similar reaction after quality-switched laser exposure. Our aim is to assess if patients with history of edible gold consumption develop chrysiasis after quality-switched laser exposure.

Demographics of Pediatric Orbital Lesions: A Tertiary Eye Center Experience in Saudi Arabia.

Orbital lesions vary in their classification, incidence, and presentation depending on the age and geographic distribution. Such lesions in the pediatric age group have been studied extensively because of the possibility of faster progression of orbital involvement and the higher risk of morbidity in this age group in which vision is still developing. In Saudi Arabia, orbital lesions were studied over a 6-year period in the late 1980s, when retinoblastoma cases used to present late with orbital involvement.

Approach to recurrent Herpes Simplex Encephalitis in children.

Herpes Simplex Encephalitis (HSE) is one of the commonest viral encephalitis and its recurrence is being increasingly reported were HSE relapse rate came up to 5%. Both herpes simplex virus (HSV) types can lead to encephalitis and it was established that HSV-1 is capable of nervous system invasion, latency, and recurrence. The recurrence of HSE used to be attributed to immunological compromise, but reports show many cases have no obvious immune system impairment.
