Peritonsillar abscess (PTA) is a common pathology in otolaryngology emergency. The treatment of PTA is usually bedside drainage or surgical removal of the tonsils (Quincy tonsillectomy) in combination with antibiotic treatment. However, patients with immune suppression might have a more difficult treatment course. Such difficulties may be further magnified within older patients. This case report will describe successful multi-modality treatment of two separate incidents of PTA developing in the context of immunosuppression...

Enzootic bovine haematuria (EBH) in cattle occurs in upland areas of the world. In India, the disease is present in isolated pockets in the Himalayas and in the Nilgiri Hills. The variation in the disease incidence has been attributed to different environmental conditions and animal rearing practices followed in the different regions. The aim of the study was to conduct field surveys in parts of EBH endemic regions of Himachal Pradesh, a north-western Himalayan state of India. Out of the total 103 plant samples collected, a total of 95 samples were identified as ferns...

A pivotal-differential evolution pattern is when two allopolyploids share a common genome, which is called pivotal, and differ with respect to the other genome or genomes, called differential. This feature induces the intergenomic recombination between chromosomes of differential genomes, which can lead to speciation. Our study is a cytomolecular insight into this mechanism which was adapted for the induction of intergenomic chromosome recombination in hybrids of synthetic amphidiploids Aegilops biuncialis × S...

A practical fabrication technique is presented to tackle the trade-off between the water flux and salt rejection of thin film composite (TFC) reverse osmosis (RO) membranes through controlled creation of a thinner active selective polyamide (PA) layer. The new thin film nano-composite (TFNC) RO membranes were synthesized with multifunctional poly tannic acid-functionalized graphene oxide nanosheets (pTA-f-GO) embedded in its PA thin active layer, which is produced through interfacial polymerization. The incorporation of pTA-f-GOL into the fabricated TFNC membranes resulted in a thinner PA layer with lower roughness and higher hydrophilicity compared to pristine membrane...

INTRODUCTION: Previous literature confirms that a mild traumatic brain injury (mTBI) may result in long-term emotional impacts and, in vulnerable subgroups, cognitive deficits. The accurate diagnosis of mTBI and its written documentation is an important first step towards providing appropriate and timely clinical care. Surveillance studies involving emergency department (ED) and hospital-based data need to be prioritised as these provide incident mTBI estimates. This project will advance existing research findings by estimating the occurrence of mTBI among those attending an ED and quantifying the accuracy of mTBI diagnoses recorded by ED staff through a comprehensive audit of ED records...

Hyperbaric oxygen (HBO₂) therapy is used in the treatment of idiopathic sudden sensorineural hearing loss (ISSNHL). Some patients, however, do not benefit from HBO₂ therapy despite several weeks of treatment. We hypothesized that early treatment response could predict treatment failure. We conducted a retrospective chart review and identified patients diagnosed with ISSNHL and recorded the pure tone average (PTA) levels prior to, after the first week and at completion of HBO₂ therapy. Early treatment response (ETR) was assessed after the first week of HBO₂ therapy, and an increase ⟨10 decibels (dB) in mean PTA level was defined as a negative ETR...

INTRODUCTION: Early access failure is an important complication of autogenous arteriovenous fistulas (AVFs). We prospectively monitored patients who underwent AVF creation using ultrasonography. METHODS: Color flow imaging was used to assess access blood flow in patients undergoing creation of a new AVF in the distal forearm preoperatively and at 1 day and 1 week postoperatively. We measured the flow volume (FV) and resistive index (RI) of the brachial artery, and the internal diameter of the brachial artery and outflow vein...

INTRODUCTION: Distal autogenous arteriovenous fistula (dAVF), considered the "gold standard" vascular access for haemodialysis, suffers from a high rate of impaired maturation. One of the usual causes is low-flow associated forearm arterial stenosis. In such cases, endovascular treatment by percutaneous transluminal angioplasty represents a helpful option to enable maturation of the vascular access.Currently, there are few reports concerning the treatment of this complication. Therefore, we describe our single-centre experience based on a retrospective review of prospectively collected data...
