Variations in skin thickness and contours pose significant challenges to reconstruction of the lower third of the nose. Human amniotic membrane allograft offers a potential alternative to tissue transfer in reconstruction of the lower third of the nose. We reviewed the procedure and photographs of a healthy 56-year-old male with a 22 × 18 mm lower third nasal defect involving full thickness skin and subcutaneous tissue. Following preparation for grafting, dehydrated human amniotic membrane was fashioned to the dimensions of the defect and applied...

Infection control practices pose a challenge to nursing care in general, but can have a huge negative impact on the perioperative process. Prior to July of 2012, our institution did not perform routine methacillin resistant staphylococcus aureus (MRSA) screening on preoperative patients with a prior history of MRSA. This resulted in patients remaining in isolation throughout their entire perioperative course. Screening for MRSA was delayed until the patient arrived in the medical surgical unit. Many of these patients were later found to have negative nasal swabs...

Ingestion of probiotics appears to have modest effects on the incidence of viral respiratory infection. The mechanism of these effects is not clear; however, there is evidence from animal models that the probiotic may have an effect on innate immune responses to pathogens. The purpose of this randomised, placebo-controlled study was to determine the effect of administration of Bifidobacterium animalis subspecies lactis Bl-04 on innate and adaptive host responses to experimental rhinovirus challenge. The effect on the response of chemokine (C-X-C motif) ligand 8 (CXCL8) to rhinovirus infection was defined as the primary endpoint for the study...

Rhinophyma is considered the end stage in the development of rosacea, accompanied by hypertrophy of the sebaceous glands, which causes an enlargement of the nose. It is an uncommon condition that often results in both functional and cosmetic impairment. A large variety of surgical and nonsurgical treatments have been published to treat it. Closure is usually obtained by wound granulating in by secondary intention, skin grafting or local flaps. Rarely these lesions can attain a giant size and pose a challenge in surgical treatment...

Nasal septal deviation is a prevalent problem that can have significant quality of life ramifications. Septoplasty is commonly performed to provide qualitative and quantitative benefit to those with nasal obstruction owing to septal deviation. Although a standard, basic technique is often adequate for individuals with mild to moderate mid to posterior septal deviation, unique challenges arise with caudal septal deviation. Herein, multiple strategies that attempt to address anterior septal deviation are discussed...

BACKGROUND: Rearing of dogs and other pets has become increasingly popular in modern society. Bacterial flora resides within the nasal and oral cavities of dogs and when chanced, can be pathogenic. Certain similarities between humans and dogs portends dangerous behavioral habits that could lead to zoonotic disease transmission. This study was aimed at isolation, identification and antibiotic profiling of bacteria from nasal swabs of apparently healthy dogs. The zoonotic risk was also considered...

Laboratory based processing and expansion to yield adequate cell numbers had been the standard in Autologous Disc Chondrocyte Transplantation (ADCT), Allogeneic Juvenile Chondrocyte Implantation (NuQu®), and Matrix-Induced Autologous Chondrocyte Implantation (MACI). Optimizing cell isolation is a key challenge in terms of obtaining adequate cell numbers while maintaining a vibrant cell population capable of subsequent proliferation and matrix elaboration. However, typical cell yields from a cartilage digest are highly variable between donors and based on user competency...

Importance: Nasal reconstruction after Mohs surgery is a unique challenge in that it must satisfy both functional and aesthetic goals. Despite some advocacy in the literature for using structural reinforcement to achieve both functional and aesthetic outcomes in soft-tissue reconstruction, no study has validated this claim by comparing reconstruction with and without structural support. Objective: To evaluate the effectiveness of and need for structural reinforcement when reconstructing the nasal alar and sidewall subunits...

Acrolein, a highly reactive unsaturated aldehyde, is generated in large amounts during smoking and is best known for its genotoxic capacity. Here, we aimed to assess whether acrolein at concentrations relevant for smokers may also exert immunomodulatory effects that could be relevant in allergy or cancer. In a BALB/c allergy model repeated nasal exposure to acrolein abrogated allergen-specific antibody and cytokine formation, and led to a relative accumulation of regulatory T cells in the lungs. Only the acrolein-treated mice were protected from bronchial hyperreactivity as well as from anaphylactic reactions upon challenge with the specific allergen...

A 74 year-old woman presented with a 9 month history of a slowly enlarging exophytic lesion over her left nasal alar. Examination revealed a firm, cystic mass fixed to underlying skin. It was pedunculated with occasional superficial telangiectasia and a violaceous hue. A differential diagnosis of dermoid or sebaceous cyst, dermatofibroma, and neurofibroma was considered. Histopathological examination confirmed the rare diagnosis of chondroid syringoma (CS), which has a reported incidence of 0.01- 0.098% of excised skin tumors...

Teaching and learning septoplasty is challenging due to the limited and intermittent visualization of the surgical site by the resident and the mentor. Our objective was to develop and test the surgical tools required to achieve optimal visualization of the surgical field during septal surgery without having to modify the way conventional septoplasty is performed. A flexible high-definition endoscope is mounted on a modified 50-mm nasal speculum. This allows real-time visualization of all steps of the surgery on the video monitor...

Vismodegib is an oral inhibitor of the Hedgehog signaling pathway and has been used to treat basal cell carcinoma (BCC) in adults. This article reports clearance of a nodular BCC of the nasal tip in an 8-year-old boy with xeroderma pigmentosum (XP). BCC can pose therapeutic challenges when located in areas that are not amenable to traditional therapies such as Mohs micrographic surgery or topical agents. Vismodegib was used at a dose of 150 mg/day to treat the boy's BCC. After 4 months of therapy, we achieved complete clinical clearance...

PURPOSE: Interleukin (IL)-9 induces allergic responses; however, the roles of anti-IL-9 antibody in the induction of tolerance remain unclear. This study investigated the effects of anti-IL-9 antibody on oral tolerance (OT) in a mouse model of allergic rhinitis (AR). METHODS: BALB/c mice were divided into 4 groups: the control, AR, OT, and OT with anti-IL-9 antibody (OT+IL9AB) groups. Ovalbumin (OVA) was used for sensitization and challenge. Mice in the OT and OT+IL9AB groups were fed OVA for immunotherapy...

Pre-stimulation of toll-like receptors (TLRs) by agonists has been shown to increase protection against influenza virus infection. In this study, we evaluated the protective response generated against influenza A/Puerto Rico/8/1934 (PR8; H1N1) virus by oral and nasal administration of live attenuated Salmonella enterica serovar Typhimurium, JOL911 strain, in mice. Oral and nasal inoculation of JOL911 significantly increased the mRNA copy number of TLR-2, TLR4 and TLR5, and downstream type I interferon (IFN) molecules, IFN-α and IFN-β, both in peripheral blood mononuclear cells (PBMCs) and in lung tissue...

BACKGROUND: Allergic rhinitis is an inflammatory disease that causes cellular influx and mediator release in the nose. These inflammatory changes might be used as nasal biomarkers to assess the efficacy of novel anti-allergic treatments. OBJECTIVE: To assess the specificity and reproducibility of nasal biomarkers in patients with allergic rhinitis after grass pollen exposure in an allergen challenge chamber. METHODS: In a monocenter pilot study, 15 patients with allergic rhinitis and 19 healthy individuals underwent two 4-hour Dactylis glomerate pollen challenges in the challenge chamber with an interval of 21 days...

Convulsive status epilepticus (CSE) is a medical emergency associated with high mortality and morbidity. The most recent definition of CSE is a convulsive seizure lasting more than 5min or consecutive seizures without recovery of consciousness. In adults, for the treatment of the early stages of CSE, diazepam, lorazepam or midazolam are the most common treatments, although the choice of agent seems less important than rapid treatment. Midazolam, when administered intramuscularly (best evidence), buccally, or nasally, is effective and safe in the pre-hospital setting...

BACKGROUND: Aspirin-exacerbated respiratory disease (AERD) is characterized by tissue eosinophilia and mast cell activation, including abundant production of prostaglandin D2 (PGD2). Group 2 innate lymphoid cells (ILC2s), which promote tissue eosinophilia and mast cell responses, undergo chemotaxis and cytokine production in response to PGD2, but it is unknown whether ILC2s are active in patients with AERD. OBJECTIVE: We sought to determine whether ILC2 numbers change in peripheral blood and the nasal mucosa during COX-1 inhibitor-induced reactions in patients with AERD...

Full-thickness defects of the entire nasal ala, including the rim, can be challenging to reconstruct. A forehead flap may provide a more imperceptible and natural-appearing reconstructed nasal ala. Previously, many authors have insisted adding cartilaginous infrastructural support for an entire, full-thickness defect to keep the postoperative alar structure symmetrical. They finally use a forehead flap after thinning of the distal covering portion subcutaneously, possibly for a Caucasian-type nasal ala. However, Asian skin has a thicker and more compact dermis than that of Caucasian skin, and the Asian ala is rounder and thicker...
