CASE REPORT: Cases of bilateral anterior nasal atresia, sometimes referred to as arhinia or partial arhinia, are extremely rare in cattle and have only been reported as single events. This report describes the birth of 16 Holstein Friesian calves over a 3-month period, all affected with bilateral atresia of the nares and anterior nasal cavity, with 2 calves having additional severe deviation of the nasomaxillary bones and nasal septum. One affected calf was born with an anatomically normal twin...

Pemphigus vulgaris is an autoimmune blistering disorder that involves the skin and mucous membranes. Few reports have described nasal and oropharyngolaryngeal lesions in pemphigus vulgaris using an endoscopic ororhinolaryngologic examination. We retrospectively reviewed the clinical records of 11 patients with pemphigus vulgaris between 2001 and 2013 with respect to their symptoms, lesion sites, lesion features, and treatments received. All patients had undergone an endoscopic ororhinolaryngologic examination...

BACKGROUND: Apolipoprotein E (ApoE) is a multifunctional protein, and its deficiency leads to the development of atherosclerosis in mice. Patients with pulmonary hypertension (PH) have reduced expression of ApoE in lung tissue. ApoE is known to inhibit endothelial and smooth muscle cell proliferation and has anti-inflammatory and anti-platelet aggregation properties. Young ApoE-deficient mice have been shown to develop PH on high fat diet. The combined role of female sex and aging in the development of PH has not been investigated before...

OBJECTIVE: To compare the use of simulator-based and patient-based obstetric ultrasound training. METHODS: This was a prospective, randomized, single-blinded trial. Eighteen consenting obstetric trainees with minimal previous ultrasound exposure were recruited. Enrolled patients were also fully consenting. Mid-trimester fetal brain anatomy in the standard planes (i.e., biparietal diameter and head circumference, cavum septum pellucidum, posterior fossa, and lateral ventricle) was chosen as a surrogate for all fetal anatomy ultrasound training...

İrfan Özyazgan
BACKGROUND: This paper presents a method in which bone or cartilage grafts are fixed to the septal cartilage with cyanoacrylate-based tissue adhesive for the treatment of septal deviation. A prospective study was designed to show the effectiveness of the technique. METHODS: Cyanoacrylate-based tissue adhesive was used to fix the cartilage or bone grafts onto the septal cartilage to straighten deviated septal cartilage in 77 patients. Regarding the patients' preoperative and postoperative nasal respiration, the following were assessed: (1) Nasal Obstruction Symptom Evaluation (NOSE) scales, (2) patient satisfaction with postoperative nasal respiration using visual analog scoring, and (3) computerized tomographic images...

REVIEW
Oren Friedman, Erdinc Cekic, Ceren Gunel
Understanding nasal anatomy and physiology are the most important points for successful functional rhinoplasty. Anatomic structures playing major roles in nasal breathing functions include the septum, and internal and external nasal valves, so physical examination of these regions is essential. Planning for functional rhinoplasty involves the identification of the sites of nasal airway obstruction or old trauma, and addressing those regions during the operation with a number of different techniques that have been described...

The neuropeptides vasopressin (AVP) and oxytocin (OT) have been implicated in the regulation of numerous social behaviors in adult and juvenile animals. AVP and OT signaling predominantly occur within a circuit of interconnected brain regions known collectively as the "social behavior neural network" (SBNN). Importantly, AVP and OT signaling within the SBNN has been shown to differentially regulate diverse social behaviors, depending on the age and/or sex of the animal. We hypothesized that variation in the display of these behaviors is due in part to age and sex differences in AVP and OT synthesis within the SBNN...

The habenula is an epithalamic structure differentiated into two nuclear complexes, medial (MHb) and lateral habenula (LHb). Recently, MHb together with its primary target, the interpeduncular nucleus (IP), have been identified as major players in mediating the aversive effects of nicotine. However, structures downstream of the MHb-IP axis, including the median (MnR) and caudal dorsal raphe nucleus (DRC), may contribute to the behavioral effects of nicotine. The afferent and efferent connections of the IP have hitherto not been systematically investigated with sensitive tracers...

Several putative deep brain photoreceptors (DBPs) have been identified, such as melanopsin, opsin 5, and vertebrate ancient opsin. The aim of this study was to elucidate the role of DBPs in gonadal regulation in the Pekin drake. As previously reported, we observed opsin-like immunoreactivity (-ir) in the lateral septum (LS), melanopsin-ir in the premammillary nucleus (PMM), and opsin 5-ir in the periventricular organ. To determine the sensitivity of the DBPs to specific wavelengths of light, drakes were given an acute exposure to red, blue, or white light...

Although the modulation of social behaviors by most major neurochemical systems has been explored, there are still standouts, including the study of vasoactive intestinal polypeptide (VIP). VIP is a modulator of circadian, reproductive, and seasonal rhythms and is well known for its role in reproductive behavior, as it is the main vertebrate prolactin-releasing hormone. Originally isolated as a gut peptide, VIP and its cognate receptors are present in virtually every brain area that is important for social behavior, including all nodes of the core "social behavior network" (SBN)...

BACKGROUND: Venous stents are commonly placed to ensure patency in patients with chronic peripheral venous insufficiency. Although serious complications are uncommon, peripheral venous stent placement can have some potentially life-threatening complications. One of the most feared, and certainly the most dramatic, complication is stent migration. CASE REPORT: We report on a 55-year-old woman with transvenous migration of an infrarenal inferior vena cava stent into the right atrium and through the intra-atrial septum...

OBJECTIVES: This is an early feasibility clinical test of mitral loop cerclage annuloplasty to treat secondary mitral valve regurgitation. BACKGROUND: Secondary mitral regurgitation is characterized by cardiomyopathy, mitral annular enlargement, and leaflet traction contributing to malcoaptation. Transcatheter mitral loop cerclage applies circumferential compression to the mitral annulus by creating a loop through the coronary sinus across the interventricular septum, protecting entrapped coronary arteries from compression, and interactive annular reduction under echocardiographic guidance...

A nanoemulsion (NE) is a surfactant-based, oil-in-water, nanoscale, high-energy emulsion with a mean droplet diameter of 400-600 nm. When mixed with antigen and applied nasally, a NE acts as a mucosal adjuvant and induces mucosal immune responses. One possible mechanism for the adjuvant effect of this material is that it augments antigen uptake and distribution to lymphoid tissues, where the immune response is generated. Biocompatible iron oxide nanoparticles have been used as a unique imaging approach to study the dynamics of cells or molecular migration...

This paper presents a methodology to access the 3D local myocyte arrangements in fresh human post-mortem heart samples. We investigated the cardiac micro-structure at a high and isotropic resolution of 3.5 µm in three dimensions using X-ray phase micro-tomography at the European Synchrotron Radiation Facility. We then processed the reconstructed volumes to extract the 3D local orientation of the myocytes using a multi-scale approach with no segmentation. We created a simplified 3D model of tissue sample made of simulated myocytes with known size and orientations, to evaluate our orientation extraction method...

We report histological appearance of a bronchogenic cyst that was incidentally found in a 78-year-old man who died from drowning related to a traumatic accident. The cyst was found in the posterior edge of the interventricular septum and was monolocular with a 5-mm diameter. The cystic wall was not associated with cartilage or the smooth muscle layer, and was lined by ciliated respiratory epithelium. Immunohistochemistry showed that many of these epithelial cells were positive for cytokeratin 7 and thyroid transcription factor-1...

Woolly hair may occur as an isolated problem of cosmetic concern or can be a part of a systemic disease (woolly hair syndrome) with underlying fatal cardiomyopathy. Two characteristic associations of woolly hair syndrome are Naxos disease and Carvajal syndrome. Naxos disease is characterized by woolly hair, palmoplantar keratoderma, and arrythmogenic right ventricular cardiomyopathy.In this report we describe a case of a young girl who presented with heart failure and was subsequently diagnosed as a case of generalized woolly hair with biventricular arrythmogenic cardiomyopathy...

Cocaine-induced midline destructive lesions (CIMDL) occur in a small subset of cocaine users, who clinically present with inflammation and necrosis of facial midline structures such as the palate, nasal septum, turbinates, and sinuses. We present a patient with CIMDL occurring concomitantly with ulcers on the cheek and upper trunk. Multiple biopsy specimens from the cutaneous and mucosal lesions consistently showed a dense dermal/submucosal infiltrate of neutrophils and plasma cells, without vasculitis or thrombosis...
