BACKGROUND: Chronic rhinosinusitis (CRS) is a common inflammatory disorder of the upper airway characterized by chronic inflammation and significant sinonasal remodeling. CRS is comprised of 2 major subgroups, based on whether polyps are present or absent. In some cases, it is characterized by colonization with opportunistic pathogens such as Pseudomonas aeruginosa (PA), Staphylococcus aureus, and other bacteria. The innate immune system of the sinonasal epithelium is the first line of defense against inhaled pathogens...

Primary spontaneous cerebrospinal fluid (CSF) rhinorrhea due to clival defect is an extremely rare presentation and only six cases have been reported in the literature so far(17). We present a unique case of a 64-year-old lady who presented with 2 years history of ongoing CSF rhinorrhea. She had similar episode at the age of 40 and suffered from meningitis. She had MRI, CT cisternogram as well as CT of brain and that showed clival defect with CSF leak into the sphenoid sinus. She underwent trans-sphenoidal repair of the clival defect with concurrent lumbar drain insertion for CSF drainage...

Cleft palate is one of the challenging problems in the field of craniofacial surgery. In particular, the conventional methods of bilateral and severe cleft palate repairs have failed to achieve normal speech. In most instances, secondary procedures such as pharyngoplasty and pharyngeal flap surgery are performed to improve speech.This study introduces secondary palatal elongation (SPE) as a new approach to cleft palate repair. The patients included usually had a short palate and unrepaired palatal muscles. The authors' procedure involved dissecting the previously repaired palatal mucosa and pushing back and cutting the nasal mucosa of the palate horizontally and further pushing it back...

AIMS: The intrauterine environment is considered to affect immunological development in fetus, leading to an increased risk of developing allergy. In particular, maternal lipopolysaccharides (LPS) administration might regulate the development of allergic disease in offspring. Several studies have shown that being obese relates to a higher prevalence of allergic diseases compared to normal weight. The present study explored the effects of inducing maternal inflammation with LPS before pregnancy on body weight, physical composition including body fat, adipokine production, and pathology of allergic rhinitis in offspring...

Short pauses or "transition-periods" at the end of expiration and prior to subsequent inspiration are commonly observed during sleep in humans. However, the role of transition periods in regulating ventilation during physiological challenges such as partial airway obstruction (PAO) has not been investigated. Twenty-nine obstructive sleep apnea patients and eight controls underwent overnight polysomnography with an epiglottic catheter. Sustained-PAO segments (increased epiglottic pressure over ≥5 breaths without increased peak inspiratory flow) and unobstructed reference segments were manually scored during apnea-free non-REM sleep...

Mohs micrographic surgery has become the standard of care for the treatment of cutaneous malignancies. Reconstructing cutaneous defects of the nose can be challenging, as form and function must be respected to the greatest extent possible. A wide range of reconstructive techniques are used. Secondary intent, primary closure, skin grafts, local flaps, and the interpolated workhorse flaps represent the spectrum of options, each with specific advantages and disadvantages. Vigilant postoperative care, including judicious use of adjunctive procedures, can improve outcomes...

BACKGROUND: Prostaglandin E2 (PGE2) is an anti-inflammatory compound that inhibits 5-lipoxygenase activity. Diminished PGE2 regulation in aspirin-exacerbated respiratory disease (AERD) leads to respiratory reactions on cyclooxygenase 1 inhibition. In vitro studies have found that exogenous PGE2 stabilizes inflammatory mediator release. OBJECTIVE: To examine whether misoprostol (oral prostaglandin E1 analogue) use during aspirin challenge and desensitization might decrease the severity of aspirin-induced symptoms and make desensitization safer for patients with AERD...

BACKGROUND: Emerging evidences indicate that post-transcriptional regulation by microRNAs is critical in allergic rhinitis (AR) pathogenesis. MircroRNA-133b (miR-133b) was recently suggested as a potential predictor of AR. However, the in vivo effect of miR-133b on AR is unclear. METHODS: AR model was established in BALB/c mice by intraperitoneal sensitization and intranasal challenge with ovalbumin (OVA). MiR-133b agomir was then intranasally administrated to mice after OVA challenge for another 7 days...

Sodium salicylate (NaSal) is a nonsteroidal anti-inflammatory drug. The putative mechanisms for NaSal's pharmacologic actions include the inhibition of cyclooxygenases, platelet-derived thromboxane A2 and NF-κB signaling. Recent studies demonstrated that salicylate could activate AMP-activated protein kinase (AMPK), an energy sensor that maintains the balance between ATP production and consumption. The anti-inflammatory action of AMPK has been reported to be mediated by promoting mitochondrial biogenesis and fatty acid oxidation...

H9N2 avian influenza virus is a zoonotic agent with a broad host range that can contribute genetic information to H5 or H7N9 subtype viruses, which are significant threats to both humans and birds. Thus, there is a great need for a vaccine to control H9N2 avian influenza. Three mutant viruses of an H9N2 virus A/chicken/Taixing/10/2010 (rTX-NS1-73, rTX-NS1-100, and rTX-NS1-128) were constructed with different NS1 gene truncations and confirmed by western blot analysis. The genetic stability, pathogenicity, transmissibility, and host immune responses toward these mutants were evaluated...

In paediatric patients, airway management can be challenging due to unique anatomical and physiological variations. Hence, a thorough history, examination and pre-operative planning are essential in securing difficult airway in paediatrics. We report a case of a 7-month-old infant with rhabdomyosarcoma of the upper lip with anticipated difficult airway. The airway was managed with three different conventional techniques (modified nasal trumpet, supraglottic airway and direct laryngoscopy) for three different procedures in the same infant...

BACKGROUND: Spontaneous spinal epidural hematoma during pregnancy is a quite rare event requiring emergent decompressive surgery in the majority of cases to prevent permanent neurological damage. Therefore, there is little data in the literature regarding anesthetic management of cervical localization during pregnancy. The potential for difficult airway management with the patient under general anesthesia is one of the major concerns that needs to be addressed to prevent further cord compression...

Veterinary vaccine development has several similarities with human vaccine development to improve the overall health and well-being of species. However, veterinary goals lean more toward feasible large-scale administration methods and low cost to high benefit immunization. Since the respiratory mucosa is easily accessible and most infectious agents begin their infection cycle at the mucosa, immunization through the respiratory route has been a highly attractive vaccine delivery strategy against infectious diseases...

Neuroendocrine neoplasms (NENs) of the head and neck are a rare group of heterogeneous epithelial neoplastic proliferations arising in virtually all of the different organs of this region, particularly in the nasal cavity, the paranasal sinuses, the nasopharynx, the larynx, the salivary glands, and the middle ear. They encompass a wide spectrum of entities ranging from very indolent neuroendocrine tumors to highly aggressive neuroendocrine carcinomas. They may represent a challenge for radiologists, oncologists, and pathologists and a correct diagnosis is crucial for the management of patients...
