RFIDs Can Improve the Patient Care Supply Chain

Technologies that increase efficiency, enhance quality, and improve patient safety are essential for all healthcare organizations. Radio frequency identification devices (RFIDs) seem to be right for this challenge. RFIDs can be integrated into all areas of the internal patient supply chain, serving as clearinghouses of information. By providing timely information on patients, processes, and equipment, RFIDs can save time and reduce costs while simultaneously improving quality and patient safety. Healthcare leaders owe it to all constituencies to take a serious look at what RFIDs can offer.     

Sclerosing polycystic adenosis of the oral cavity

Minor salivary glands are ubiquitous in the oral cavity, and related diseases are often indolent and asymptomatic. We describe the unusual features of sclerosing polycystic adenosis, and its similarities to more sinister conditions of the minor salivary glands. Its importance is currently uncertain and research points to a pathogenesis that is neoplastic, which can create ambiguity. Sclerosing polycystic adenosis is a newly-discovered condition that merits further discussion and research to evaluate its full impact.     

How to use noninvasive positive airway pressure device data reports to guide clinical care

There has been a significant increase in the past few decades in the number of children receiving noninvasive positive airway pressure (PAP) therapy at home. At present, PAP therapy can be successfully used in children of all ages, for a variety of indications. Data acquired from PAP devices is clinically useful, providing objective information regarding adherence, leak, and efficacy of PAP therapy. However, guidelines outlining a standardized approach to interpretation of PAP device data in pediatrics is currently lacking. Given the rapidly expanding use of PAP therapy in pediatric practice, we aim to provide an overview of the interpretation of data reports, otherwise called “data downloads,” from PAP devices and illustrate how they can be used to guide clinical care.     

Molecular interactions of dioxins and DLCs with the ketosteroid receptors: an in silico risk assessment approach

Dioxins and dioxin-like compounds (DLCs) are the ones with poor water solubility and low volatility, resistant to physical, chemical and biological processes, persistent in the environment even under extreme conditions. Due to lipophilic nature, they get adhered to the fatty material and concentrate through biomagnification and bioaccumulation, thereby easily getting incorporated into food chains, paving the way to endocrine disruption via modulation of various human receptors. This in turn leads to certain adverse health effects. In the present study, a total of 100 dioxins and DLCs were taken and their binding pattern was assessed with the ketosteroid receptors, i.e. androgen (hAR), glucocorticoid (hGR), progesterone (hPR) and mineralocorticoid (hMR) in comparison to the corresponding natural steroids and a known endocrine disrupting xenobiotic, Bisphenol A (BPA). Most of the DLCs, particularly those bearing hydroxyl (-OH) group showed considerable affinities with ketosteroid receptors. On comparing D scores of all the dioxins and DLCs against all four receptors, compound 8-hydroxy-3,4-dichlorodibenzofuran(8-OH-DCDF) exhibited least D score of -9.549?kcal mol^?1 against hAR. 3,8-Dihydroxy-2-chlorodibenzofuran(3,8-DiOH-CDF), 4′-hydroxy-2,3,4,5-tetrachlorobiphenyl (4′-OH-TCB) and 4-hydroxy-2,2′,5′-trichlorobiphenyl(4-OH-TCB) also showed comparable molecular interactions with the ketosteroid receptors. These interactions mainly include H-bonding, π–π stacking, hydrophobic, polar and van der Waals’ interactions. In contrast, BPA and some natural ligands tested in this study showed lower binding affinities with these receptors than certain DLCs reported herein, i.e. certain DLCs might be more toxic than the proven toxic agent, BPA. Such studies play a pivotal role in the risk assessment of exposure to dioxins and DLCs on human health.     

Afr1p Expression During Mitosis is Dependent on Mpk1p in Saccharomyces cerevisiae

Afr1p induced by the mating pheromone confers α-factor resistance and leads to elongated bud during mitosis. In the present investigation Afr1p was expressed during mitosis and its expression amount was achieved to the level induced by α-factor. Additionally, Afr1p expression during mitosis was completely dependent on Mpk1p. The α-factor resistance was also dependent on the specific elements in the promoter of Afr1p. These results suggested that Afr1p may have important functions during mitosis.     

Myiasis in Kuwait: nosocomial infections caused by lucilia sericata and Megaselia scalaris

Myiasis, the invasion of live human tissue by larvae of Diptera, is reported in the nasopharynx and a leg wound in two patients who were hospitalized for more than 72 hours in Mubarak Al-Kabeer Teaching Hospital in Kuwait City, Kuwait. On the fourth and fifth days after a 10-year-old Kuwaiti boy was admitted to the hospital intensive care unit in a bloodied and comatose state following a traffic accident, 'worms' that came out of his nostrils were fixed, cleared, and identified as second and third instar of Lucilia sericata (Diptera: Calliphoridae). After 14 days, 'worms' were seen in the original dressing of a 35-year-old Iranian man admitted to the Orthopedic Unit of the hospital with multiple lacerations and fractures. The larvae, in various stages of development, were identified as those of Megaselia scalaris (Diptera: Phoridae). Since the presence of larvae in both patients was recorded after a stay of at least 3-4 days in the hospital, by definition, these infestations are considered nosocomial.
