OBJECTIVE/HYPOTHESIS: Vagus nerve stimulation (VNS) is an established therapy for drug-resistant epilepsy, depression, and a number of other disorders. Transcutaneous stimulation of the auricular branch of the vagus nerve (tVNS) has been considered as a non-invasive alternative. Several functional magnetic resonance imaging (fMRI) studies on the effects of tVNS used different stimulation parameters and locations in the ear, which makes it difficult to determine the optimal tVNS methodology...

We report a case of pseudohyperglycaemia on a capillary blood glucose measurement taken from fingers stained with sugar (fructose). A 76-year-old patient with type 1 diabetes received emergency attention at home because of a coma. The first capillary blood glucose measurement collected from a finger revealed a concentration higher than the reference limits, misleading the clinician. After starting symptomatic treatment, a second blood glucose measurement was taken. This measurement, taken at the earlobe, revealed profound hypoglycaemia (0...

BACKGROUND: Increased pain sensitivity is characteristic for patients with chronic pain disorder with somatic and psychological factors (F45.41). Persistent stress can induce, sustain, and intensify pain sensitivity, thereby modulating pain perception. In this context, it would be favorable to investigate which psychosocial stressors are empirically linked to pain sensitivity. OBJECTIVES: The aim of this study was to examine the relationship between psychosocial stressors and pain sensitivity in a naturalistic sample of patients with chronic pain disorder with somatic and psychological factors (F45...

OBJECTIVE: Cryptotia is one of the most common malformations of the upper auricle with aesthetic and functional consequences, however there is no standard treatment. We present the surgical technique and results of a kite flap procedure which can be used in the different cryptotia subtypes. METHODS: We reviewed all patients treated in our department from 2010 to 2015, using a mastoid fascia kite flap technique. The incision of this local flap follows the retro-auricular sulcus along the rim of the helix superiorly and drawing a skin paddle inferiorly...

The anatomical basis for auricular flaps used in multiple aesthetic and reconstructive procedures is currently based on a random distribution of the underlying arterial network. However, recent findings reveal a systematic pattern as opposed to the present concepts. Therefore, we designed this study to assess the arterial vascular pattern of the auricle in order to provide reliable data about the vascular map required for surgical interventions. Sixteen human auricles from eight body donors (five females/three males, 84...

OBJECTIVE: Atherosclerotic coronary artery disease is a leading cause of death, worldwide. Diagonal earlobe crease (DELC) has been suggested as a simple, noninvasive marker of cardiovascular disease. Although epicardial adipose tissue (EAT) thickness and carotid intima media thickness (CIMT) are closely related to atherosclerosis, the relation between EAT, CIMT, and DELC had yet to be studied. The present objective was to analyze this association. METHODS: Subjects were apparently healthy individuals referred to the cardiology outpatient clinic...

The gastric cardia-the small area around the cardiac orifice including the abdominal esophagus-is an important target area for abdominal and thoracic surgeries, especially for laparoscopic procedures. In this study of 28 cadavers, a peritoneal earlobe-like appendage near the angle of His was identified as a useful indicator of the lateral margin of the abdominal esophagus, which is otherwise obscure because the peritoneum continues to the diaphragm without definite demarcation of this margin. This structure, which appears equivalent to the epiploic appendages, was commonly found to be present (in 22/28, 78...

Few studies verified the reliability of the lactate threshold determined by Dmax method (LTDmax) in runners and it remains unclear the effect of the regression model and the final speed on the reliability of LTDmax. This study aimed to examine the test-retest reliability of the speed at LTDmax in runners, considering the effects of the regression models (exponential-plus-constant vs third-order polynomial) and final speed criteria (complete vs proportional). Seventeen male, recreational runners performed 2 identical incremental exercise tests, with increments of 1 km·h(-1) each for 3 min on treadmill to determine peak treadmill speed (Vpeak) and lactate threshold...

OBJECTIVE: To investigate the effect of a novel topical wound-healing agent, low-concentration povidone-iodine ointment (LPIO) with a hydrophobic white petrolatum-rich base on skin-wound models in rats and rabbits. METHOD: The therapeutic efficacy of topically applied LPIO was compared to that of standard-concentration povidone-iodine ointment (SPIO) and non-treatment control, using a full-thickness skin-wound model in 24 hairless rats and a full-thickness skin-defect model in rabbit earlobes...

BACKGROUND: Prominent ear deformity (PD) is an unacceptable condition of pinna that affects 5% of the population and is associated with emotional stress, behavioral disturbances, and social restrictions in relationships. Conchal hypertrphy, inadequate formation of antihelical fold, earlobe placement ahead than it should be, or various combinations of these changes are main characteristics of PD. Many surgical techniques have been described for the PD.The authors' aim was to present laterally based postauricular dermal flap combination with cartilage-sparing methods and effectiveness of this technique in suture extrusion prevention and reducing the rate of recurrence with long-term results...

BACKGROUND: Onchocerciasis, caused by the parasitic nematode, Onchocerca volvulus afflicts some 37 million people worldwide, and is the second leading infectious cause of blindness globally. The only currently recommended drug for treatment of the disease, ivermectin, is only microfilaricidal and has serious adverse effects in individuals co-infected with high loads of Loa loa microfilariae (mf), prompting the search for new and better drugs. Onchocerciasis drug discovery studies have so far been based on in vivo models using Onchocerca species which are not the closest to O...

BACKGROUND: Earlobe keloids are usually recalcitrant to treatment and have a high rate of recurrence. Verapamil is a calcium channel antagonist that has been shown to inhibit the synthesis/secretion of extracellular matrix molecules and increase collagenase. OBJECTIVES: This prospective study was designed to evaluate the results of treatment of recurrent earlobe keloids using keloidectomy with core fillet flap and intralesional verapamil injection. METHODS: Nineteen keloids in 16 patients were treated using this technique with intralesional verapamil injection given intraoperatively, then every 2 weeks for 3 months, with postoperative follow-up for 18 months...

PURPOSE: Brachytherapy (BT), due to rapid dose fall off and minor set-up errors, should be superior to external beam radiotherapy (EBRT) for treatment of lesions in difficult locations like nose and earlobe. Evidences in this field are scarce. We describe computed tomography (CT) based surface mould BT for non-melanoma skin cancers (NMSC), and compare its conformity, dose coverage, and tissue sparing ability to EBRT. MATERIAL AND METHODS: We describe procedure of preparation of surface mould applicator and dosimetry parameters of BT plans, which were implemented in 10 individuals with NMSC of nose and earlobe...

BACKGROUND: Earlobe color is a naturally and artificially selected trait in chicken. As a head furnishing trait, it has been selected as a breed characteristic. Research has demonstrated that white/red earlobe color was related to at least three loci and sex-linked. However, there has been little work to date to identify the specific genomic regions and genes response to earlobe color in Rhode Island Red chickens. Currently, it is possible to identify the genomic regions responsible for white/red earlobe in Rhode Island Red chicken to eliminate this gap in knowledge by using genome-wide association (GWA) analysis...

An 86-year-old woman was referred for treatment of a lentigo maligna melanoma on the left earlobe, confirmed by cutaneous biopsy. The resulting surgical defect involved the earlobe's full thickness. The authors outline a simple method for reconstructing the entire lobe in one stage, without grafts, whilst offering a pleasant appearance. Earlobe deformity may be congenital or, more often, acquired due to trauma, burns or surgery. Ear lobules are an important reference point for facial symmetry and they serve decorative purposes like wearing earrings...

The appearance of the ear is an important component of the facial characteristics. Lower auricular malformations are less frequent than total or upper auricular malformations. The patients are affected unilaterally in general. Cleft earlobe is frequently encountered among earlobe anomalies. The presented case may be classified as longitudinal type according to Kitayama (Jpn J Plast Reconstr Surg 11:663-670, 1980). Many of the correction methods may lead to patient discomfort due to possible conspicuous scar...

AIMS: To examine the accuracy and acceptability of capillary blood glucose monitoring using the earlobe. BACKGROUND: In current practice, blood samples for capillary blood glucose monitoring are obtained from the fingertip. Because obtaining blood samples from the fingertip is sometimes contraindicated, it is necessary to identify an alternative site for the procedure. DESIGN: A single-patient design with repeated measurements. METHODS: Patients from an outpatient clinic and four medical wards were recruited to the study, in 2014, if they met one of the following criteria: (i) were in a relatively stable glycaemic state; (ii) were currently receiving intravenous infusion; (iii) had been diagnosed with chronic renal impairment or (iv) were aged 65 years or above and bedbound...

BACKGROUND: Recognition of the effects of aging on the ear and the mechanisms leading to ear deformity associated with facelift procedures aid in achieving improved aesthetic results. In 2009, the author developed a novel rhytidectomy technique to provide more natural-looking results than those achieved through other facelift procedures, which often result in facial and ear distortion/deformity. This technique is designed to optimize aesthetic outcomes by employing incisions hidden within the ear, autologous fat transfer to restore normally lost facial volume, and absorbable bidirectional sutures, all of which allow less skin removal and shorter, more concealable scars within the inside perimeter of the ear, and thus less-distorted facial contours...
