Emerging strategies for managing differentiated thyroid cancers refractory to radioiodine

Alexandros G. SfakianakisστοΕνδοκρινολογίαΠριν από 1 λεπτό
Abstract Efficient treatment of radio refractory thyroid cancer is still a major challenge. The recent identification of genetic and epigenetic alterations present in almost all differentiated tumors has revealed novel molecular targets, which can hopefully be exploited to create new treatments for these tumors. This review looks briefly at some of the innovative strategies currently being investigated for the treatment the radioiodine-resistant thyroid cancers. from Endocrinology via ola Kala on Inoreader http://ift.tt/1OjBiXr via IFTTT

Lip sparing mandibulotomy

Alexandros G. SfakianakisστοOtoRhinoLaryngology - Alexandros G. SfakianakisΠριν από 15 δευτερόλεπτα
Lip sparing mandibulotomy: avoiding morbidity: Within head and neck cancer surgery, access to the oropharynx will sometimes necessitate a mandibulotomy with a lip split. Different lip incisions have been described over the years in an attempt to reduce the morbidity of lip scarring but patients are often still left with unsatisfying results which only serves as a reminder of their past illness. Furthermore, by avoiding a lip split the integrity of the orbicularis oris sphincter is preserved and therefore function not compromised.

The use of 3D CT reconstruction in aiding the surgical management of Eagle's syndrome: Introduction: Eagle's (or stylohyoid) syndrome describes a series of symptoms resulting from the elongation of the styloid process. For surgical management, a styloidectomy can be performed using either the intraoral transpharyngeal) or extraoral approach. Eagle introduced the intraoral transpharyngeal approach which has the advantage of avoiding an external scar and damage to the facial nerve. However, this method was discouraged due to poor visualisation and the risk of injury to major vessels.

Can Tinnitus Go Away: If you have tinnitus, you may want nothing more than for your hearing condition to go away. Tinnitus is sometimes confused with hearing loss, but it is not related to loss of hearing. Instead, it is most aptly described as a ringing sound in the ears. People who have tinnitus may describe the sound in different ways, and it may not always be heard as a ring. For example, it may sound like a hiss, a chirp, a buzz, a whistle or other types of sounds. These sounds may be continuous or intermittent, and they may seem to be very loud or soft. If you have this condi... περισσότερα »

Pitch generally decreases when *α* increases from 0 to 1, although the salience of pitch change varies across CI users. This study aimed to identify the mechanism of pitch changes with pTP-mode current steering and the factors ... περισσότερα »

Alexandros SfakianakisστοHead and Neck Diseases by Alexandros G.SfakianakisΠριν από 1 ώρα
Abstract Poorer hearing in the presence of background noise is a significant problem for the hearing impaired. Ototoxic drugs, ageing, and noise exposure can damage the sensory hair cells of the inner ear that are essential for normal hearing sensitivity. The relationship between outer hair cell (OHC) loss and progressively poorer hearing sensitivity in quiet or in competing background noise is supported by a number of human and animal studies. In contrast, the effect of moderate inner hair cell (IHC) loss or dysfunction shows almost no impact on behavioral measures of hearing sens... περισσότερα »

Summary Severe skin diseases and systemic fungaemia are caused by *Malassezia pachydermatis* and *Candida albicans* respectively. Antifungal therapies are less effective because of chronic character of infections and high percentage of relapses. Therefore, there is a great need to develop new strategies of antifungal therapies. We previously found that oxythiamine decreases proliferation of yeast (*Saccharomyces cerevisiae*), therefore we suggest that thiamine antivitamins can be considered as antifungal agents. The aim of this study was the comparison of thiamine antivitamins (ox...περισσότερα »

Increasing development of antimicrobial resistance is driving a resurgence in interest in phage therapy: the use of bacteriophages to treat bacterial infections. As the lytic action of bacteriophages is unaffected by the antibiotic resistance status of their bacterial target it is thought that phage therapy may have considerable potential in the treatment of a wide range of topical and localized infections. As yet this interest has not extended to intravenous (IV) use, which is surprising given that the historical record shows that phages are likely to be safe and effective when d... περισσότερα »

Dermatophytosis in northern Africa

Alexandros SfakianakisστοHead and Neck Diseases by Alexandros G.SfakianakisΠριν από 1 ώρα
Summary Infections caused by dermatophytes are a global problem and a major public health burden in the world today. In Africa, especially in the northern geographical zone, dermatophytic infections are being reported at an alarming rate. This is mostly because of some local but unique cultural practices, socioeconomic and environmental conditions, lack of reliable diagnostic personnel and facilities and ineffective treatment. Interestingly, the pathogen spectrum and the clinical manifestation are most times different from what is seen in other continents. Several epidemiological ... περισσότερα »

Thiamine antivitamins – an opportunity of therapy of fungal infections caused by Malassezia pachydermatis and Candida albicans

Alexandros SfakianakisστοHead and Neck Diseases by Alexandros G.SfakianakisΠριν από 1 ώρα
Summary Severe skin diseases and systemic fungaemia are caused by *Malassezia pachydermatis* and *Candida albicans* respectively. Antifungal therapies are less effective because of chronic character of infections and high percentage of relapses. Therefore, there is a great need to develop new strategies of antifungal therapies. We previously found that oxythiamine decreases proliferation of yeast (*Saccharomyces cerevisiae*), therefore we suggest that thiamine antivitamins can be considered as antifungal agents. The aim of this study was the comparison of thiamine antivitamins (ox...περισσότερα »

Lytic Action of the Truncated yncE Gene in Escherichia coli

Alexandros SfakianakisστοHead and Neck Diseases by Alexandros G.SfakianakisΠριν από 1 ώρα
Abstract We recently found lytic action of the truncated *yncE* gene. When the truncated *yncE* gene of *Salmonella enterica* serovar Paratyphi A was expressed in *Escherichia coli* DH5α under the control of the Ara promoter, bacterial growth was markedly inhibited. In the present study, we characterized this lytic action. The N-terminal 103 aa of YncE, containing a signal peptide, was demonstrated to be essential for inhibition. Microscopic observation showed that the bacterial envelope of *E*. *coli* was damaged by the expression of truncated *yncE*, resulting in the release of ...περισσότερα »

Safety and efficacy of phage therapy via the intravenous route

Alexandros SfakianakisστοHead and Neck Diseases by Alexandros G.SfakianakisΠριν από 1 ώρα
Increasing development of antimicrobial resistance is driving a resurgence in interest in phage therapy: the use of bacteriophages to treat bacterial infections. As the lytic action of bacteriophages is unaffected by the antibiotic resistance status of their bacterial target it is thought that phage therapy may have considerable potential in the treatment of a wide range of topical and localized infections. As yet this interest has not extended to intravenous (IV) use, which is surprising given that the historical record shows that phages are likely to be safe and effective when d... περισσότερα »

Adding mucins to an in vitro batch fermentation model of the large intestine induces changes in microbial population isolated from porcine feces depending on the substrate

Alexandros SfakianakisστοHead and Neck Diseases by Alexandros G.SfakianakisΠριν από 1 ώρα
Adding mucus to *in vitro* fermentation models of the large intestine showed that some genera, namely lactobacilli, are dependent on host-microbiota interactions and that they rely on mucosa layers to increase their activity. This study investigates whether this dependence on mucus is substrate-dependent and to which extend other genera are impacted by the presence of mucus. Inulin and cellulose were fermented *in vitro* by a fecal inoculum from pig in the presence or not of mucin-beads in order to compare fermentation patterns and bacterial communities.

Ubiquitous SAR11 *Alphaproteobacteria* numerically dominate marine planktonic communities. Because they are excruciatingly difficult to cultivate, there is comparatively little known about their physiology and metabolic responses to long- and short- term environmental changes. As surface oceans take up anthropogenic, atmospheric CO2, the consequential process of ocean acidification could affect the global biogeochemical significance of SAR11. Shipping accidents or inadvertent release of chemicals from industrial plants can have strong short-term local effects on oceanic SAR11. Thi... περισσότερα »
