Sinus Balloon Dilation as Treatment for Acute Sphenoid Sinusitis with Impaired Vision for a Child

Alexandros G. SfakianakisστοΟγκολογίαΠριν από 47 δευτερόλεπτα
This paper is about sinus balloon dilatation in treatment of acute left sphenoid sinusitis with left impaired vision in a child. Balloon catheter dilatation (BCD) of the sinus ostia is a new technique. It has been shown to be a minimally invasive technique to manage chronic sinusitis. However, this method is rarely used in the treatment of acute sinusitis. So far, we know of no reported cases of sinus balloon dilatation in treatment of this case, especially for children. from Cases via ola Kala on Inoreader http://ift.tt/1LFz0vt via IFTTT

Dispatcher-assisted compression-only cardiopulmonary resuscitation provides best quality cardiopulmonary resuscitation by laypersons: A randomised controlled single-blinded manikin trial.

Alexandros G. SfakianakisστοAnaesthesiologyΠριν από 54 δευτερόλεπτα
BACKGROUND: High-quality cardiopulmonary resuscitation (CPR) by laypersons is a key determinant of both outcome and survival for out-of-hospital cardiac arrest. Dispatcher-assisted CPR (telephone-CPR, T-CPR) increases the frequency and correctness of bystander-CPR but results in prolonged time to first chest compressions. However, it remains unclear whether instructions for rescue ventilation and/or chest compressions should be recommended for dispatcher-assisted CPR. OBJECTIVE: The aim of this study was to evaluate both principles of T-CPR with respect to CPR quality. DESIGN: Rando...περισσότερα »

Publication date: March 2016 Source:European Journal of Cancer, Volume 56 Author(s): Charlotte Vrinten, Jane Wardle ObjectivesDespite improved outcomes, cancer remains widely feared, often because of its association with a long and protracted death as opposed to the quick death that people associate with that other common cause of adult mortality: heart disease. Former editor-in-chief of… Continue reading Is cancer a good way to die? A population-based survey among middle-aged and older adults in the United Kingdom

Determination of the appropriate sizes of oropharyngeal airways in adults: correlation with external facial measurements: A randomised crossover study.

BACKGROUND: Two external facial measurements have been recommended as reference criteria for estimating appropriate oropharyngeal airway sizes: the distances between the maxillary incisors to the angle of the mandible, and that from the corner of the mouth to the angle of the mandible. OBJECTIVE: To compare the two guidelines and to determine the optimal external […]

Dispatcher-assisted compression-only cardiopulmonary resuscitation provides best quality cardiopulmonary resuscitation by laypersons: A randomised controlled single-blinded manikin trial.

BACKGROUND: High-quality cardiopulmonary resuscitation (CPR) by laypersons is a key determinant of both outcome and survival for out-of-hospital cardiac arrest. Dispatcher-assisted CPR (telephone-CPR, T-CPR) increases the frequency and correctness of bystander-CPR but results in prolonged time to first chest compressions. However, it remains unclear whether instructions for rescue ventilation and/or chest compressions should be recommended […]

Molecular Impairment Mechanisms of Novel OPA1 Mutations Predicted by Molecular Modeling in Patients With Autosomal Dominant Optic Atrophy and Auditory Neuropathy Spectrum Disorder.

Hypothesis: Different missense mutations of the optic atrophy 1 gene (OPA1) identified in optic atrophy patients with auditory neuropathy spectrum disorder (ANSD) induce functional impairment through different molecular mechanisms. Background: OPA1 is the gene responsible for autosomal dominant optic atrophy (ADOA), but some of its mutations are also associated with ANSD. OPA1 is a member […]

Repeated Postoperative Follow-up Diffusion-Weighted Magnetic Resonance Imaging to Detect Residual or Recurrent Cholesteatoma.

Objective: In our institution, follow-up diffusion-weighted imaging (DWI) after cholesteatoma surgery is performed at least twice. The aim of this study was to determine the yield of the second follow-up DWI (D-W MRI-2) in patients in whom the first postoperative DWI (D-W MRI-1) was negative for residual or recurrent cholesteatoma. Study Design: A retrospective analysis. […]

Lack of Evidence for Nonotosclerotic Stapes Fixation in Human Temporal Bone Histopathology.

Hypothesis: Nonotosclerotic stapes fixation does not represent a significant cause of stapes ankylosis in patients undergoing stapedectomy; the vast majority have otosclerosis. Background: Nonotosclerotic stapes fixation has been proposed as the diagnosis in 30 to 40% of patients undergoing stapedectomy (after excluding rare congenital, systemic, and syndromic causes of stapes fixation and tympanosclerosis). This finding […]

The first decade of estrogen receptor cistromics in breast cancer

The advent of genome-wide transcription factor profiling has revolutionized the field of breast cancer research. Estrogen receptor alpha (ERα), the major drug target in hormone receptor-positive breast cancer, has been known as a key transcriptional regulator in tumor progression for over 30 years. Even though this function of ERα is heavily exploited and widely accepted […]

Vitamin D deficiency impairs skeletal muscle function in a smoking mouse model

Chronic obstructive pulmonary disease (COPD) is associated with skeletal muscle dysfunction. Vitamin D plays an important role in muscle strength and performance in healthy individuals. In COPD, vitamin D deficiency is highly prevalent but its role in skeletal muscle dysfunction is unclear. We examined the time-course effect of vitamin D deficiency on limb muscle function […]

Palmitoylated PrRP analog decreases body weight in rats with DIO but not in ZDF rats

Anorexigenic neuropeptides produced and acting in the brain have the potential to decrease food intake and ameliorate obesity but are ineffective after peripheral application, owing to a limited ability to cross the blood-brain barrier. We have designed lipidized analogs of prolactin-releasing peptide (PrRP), which is involved in energy balance regulation as demonstrated by obesity phenotypes […]

Magnetic resonance analysis of malignant transformation in recurrent glioma

Alexandros G. SfakianakisστοΝευρολογία κ' ΝευροχειρουργικήΠριν από 1 ώρα
Background Patients with low-grade glioma (LGG) have a relatively long survival, and a balance is often struck between treating the tumor and impacting quality of life. While lesions may remain stable for many years, they may also undergo malignant transformation (MT) at the time of recurrence and require more aggressive intervention. Here we report on a state-of-the-art multiparametric MRI study of patients with recurrent LGG. Methods One hundred and eleven patients previously diagnosed with LGG were scanned at either 1.5 T or 3 T MR at the time of recurrence. Volumetric and i... περισσότερα »

Review article: bile acid diarrhoea – pathogenesis, diagnosis and management

Alexandros G. SfakianakisστοThe OesophagusΠριν από 1 ώρα
Summary Background Bile acid diarrhoea results from imbalances in the homoeostasis of bile acids in the enterohepatic circulation. It can be a consequence of ileal disease/dysfunction, associated with other GI pathology or can be idiopathic. Aims To summarise the different types of bile acid diarrhoea and discuss the currently available diagnostic methods and treatments. Results Bile acid diarrhoea is found in up to 40% of patients diagnosed as having functional diarrhoea/IBS-D, and in up to 80% of patients who have undergone ileal resection.

Strong TCR-mediated signals suppress integrated stress responses induced by KDELR1 deficiency in naive T cells

Alexandros G. SfakianakisστοAllergy Rhinology Immunology AsthmaΠριν από 1 ώρα
KDEL receptor 1 (KDELR1) regulates integrated stress responses (ISR) to promote naive T-cell survival *in vivo*. In a mouse line having nonfunctional KDELR1, T-Red (naive T-cell reduced) mice, polyclonal naive T cells show excessive ISR and eventually undergo apoptosis. However, breeding T-Red mice with TCR-transgenic mice bearing relatively high TCR affinity rescued the T-Red phenotype, implying a link between ISR-induced apoptosis and TCR-mediated signaling. Here, we showed that strong TCR stimulation reduces ISR in naive T cells. In mice lacking functional KDELR1, surviving nai...περισσότερα »

Opposing roles of LTB4 and PGE2 in regulating the inflammasome-dependent scorpion venom-induced mortality

Article Scorpion venom causes thousands of deaths worldwide. Here the authors show that the envenomation acts via prostaglandin E2 leading to inflammasome activation and lung pathology, counterbalanced by inflammation-limiting LTB4, and that COX inhibitors or exogenous LTB4 rescue the venom-induced mortality in mice.
