Yunhui Jiang, Jian Tang, Xiaoliang Wang, Chao Shen
In this paper, thorough improvement of pulse monitoring and analysis equipment with a headset structure is presented. In order to study the most suitable infrared wavelength for the acquisition of the pulse wave at the earlobe, Monte Carlo simulation was adapted. Both high frequency noise and baseline drift, generated in the signal acquisition process, are considered. To further optimize the system design and improve accuracy, for the sensor's dimensional drift, the corresponding compensation was carried on in the software...

We describe a 69-year-old man who presented with a right sternocleidomastoid intramuscular abscess that grew Propionibacterium acnes. Despite initial improvement with antibiotics, he subsequently developed signs and symptoms fulfilling diagnostic criteria for hemophagocytic lymphohistiocytosis (HLH)-fevers, cytopenias, hyperferritinemia, splenomegaly, and low natural killer cell activity. The patient improved spontaneously but at outpatient follow-up complained of erythema over the bridge of his nose as well as bilateral ear redness sparing the earlobes at which point relapsing polychondritis (RP) was diagnosed...

OBJECTIVE: Human scalp electroencephalogram (EEG) is widely applied in cognitive neuroscience and clinical studies due to its non-invasiveness and ultra-high time resolution. However, the representativeness of the measured EEG potentials for the underneath neural activities is still a problem under debate. This study aims to investigate systematically how both reference montage and electrodes setup affect the accuracy of EEG potentials. APPROACH: First, the standard EEG potentials are generated by the forward calculation with a single dipole in the neural source space, for eleven channel numbers (10, 16, 21, 32, 64, 85, 96, 128, 129, 257, 335)...

BACKGROUND: Neuropsychological effects of considerably low levels of lead exposure are observed in children, and a reliable and possibly painless technique that can detect such levels is required for the assessment of such exposure. We examined whether the blood lead (BPb) concentrations obtained from the earlobe were as valid and useful as those from the median cubital vein. METHODS: Paired blood samples were collected from the earlobe and cubital vein of 112 Japanese participants occupationally unexposed to lead, and the BPb levels were determined using ICP-MS...

The genetic basis of earlobe attachment has been a matter of debate since the early 20th century, such that geneticists argue both for and against polygenic inheritance. Recent genetic studies have identified a few loci associated with the trait, but large-scale analyses are still lacking. Here, we performed a genome-wide association study of lobe attachment in a multiethnic sample of 74,660 individuals from four cohorts (three with the trait scored by an expert rater and one with the trait self-reported). Meta-analysis of the three expert-rater-scored cohorts revealed six associated loci harboring numerous candidate genes, including EDAR, SP5, MRPS22, ADGRG6 (GPR126), KIAA1217, and PAX9...

BACKGROUND: Visible age-related signs indicate biological age, as individuals that appear old for their age are more likely to be at poor health, compared with people that appear their actual age. The aim of this study was to investigate whether alcohol and smoking are associated with four visible age-related signs (arcus corneae, xanthelasmata, earlobe crease and male pattern baldness). METHODS: We used information from 11 613 individuals in the Copenhagen City Heart Study (1976-2003)...

Taurine can affect the energy system metabolism, specifically the lipid metabolism, since an increase in lipid oxidation may promote carbohydrate savings. We hypothesized that taurine supplementation associated with high-intensity exercise could increase levels of lipolysis, benefiting swimmer performance. Nine male competitive swimmers performed two 400-m front crawl maximal efforts with a 1-week washout, and the athletes received 6 g of taurine (TAU) or placebo (PLA) supplementation 120 min before performing the effort...

RATIONALE: Relapsing polychondritis (RP) is a multisystemic, progressive disease of unknown etiology characterized by recurrent inflammation and progressive cartilage destruction. It can involve all types of cartilage including ears and nose, tracheobronchial tree, joints, and any other tissue rich in proteoglycans such as heart, eyes, and blood vessels. Recurrent chondritis can be life-threatening if the respiratory tract, heart valves, or blood vessels are affected. To date there is no data in the literature on the post solid organ transplantation RP...

We investigated the frequency and clinical significance of diagonal earlobe crease (DELC) in cognitively impaired patients using imaging biomarkers, such as white matter hyperintensities (WMH) on MRI and amyloid-β (Aβ) PET. A total of 471 cognitively impaired patients and 243 cognitively normal (CN) individuals were included in this study. Compared with CN individuals, cognitively impaired patients had a greater frequency of DELC (OR 1.6, 95% CI 1.1-2.2, P = 0.007). This relationship was more prominent in patients with dementia (OR 1...

Patients are increasingly seeking repair of their earlobes following ear gauging. Research has shown that current repair techniques either excessively reduce the lobular volume or leave an obvious scar along the free edge of the earlobe. In our case series, we describe the use of a novel technique for repairing earlobes following ear gauging using a rolling earlobe flap that preserves the lobular volume and avoids leaving a scar on the free edge of the lobule. The procedure was performed on 3 patients (6 earlobes) who had defects from ear gauging that ranged from 3...

Any cutaneous cyst differentiating toward two or more pilosebaceous components is known as follicular hybrid cyst (FHC). A combination of epidermal and trichilemmal cyst is its most frequent example. Other combinations of pilosebaceous derivatives occur uncommonly as well. The histogenesis of this condition has been controversial. In this latest report, we describe an unusual FHC from the earlobe of a 19-year-old male, which expressed the cohabitation of epidermal cyst and steatocystoma. A sharp transition was noted between the two kinds of epithelial components...

Earlobe creases are surrogate markers for high risk of cardiovascular disease. There is no data concerning earlobe creases among hemodialysis patients, who have an increased risk of cardiovascular disease. A cross-sectional study was conducted to determine the prevalence of earlobe creases and their association with prevalent cardiovascular disease among hemodialysis patients. Patients undergoing hemodialysis were recruited from five outpatient hemodialysis centers. Both earlobes were photographed during a dialysis session with the patient in a supine position and the photos evaluated independently by two experienced nephrologists blinded to the participants' clinical characteristics...

Over the course of a month, this 34-year-old woman had sought care at our facility--and another--on 3 separate occasions for painful bruises (visits #1 and #3) and deep vein thrombosis (visit #2). The bruises first appeared acutely on her arms, prompting her first visit to our ED and leading to a hospital stay. Several weeks later, the patient developed new bruise-like lesions on her earlobes, face, trunk, and lower extremities. In between these 2 visits, the patient was seen in another ED (and admitted) for right upper extremity DVT and was started on enoxaparin, followed by warfarin...

Sirolimus is an immunosuppressant drug used to prevent organ rejection in transplant patients. We describe a man with sirolimus-associated pruritus and review the features of this adverse event in other individuals receiving this drug. The patient was a 67-year-old heart transplant recipient receiving sirolimus as part of his immunosuppressive regimen. He developed severe pruritus over the distal extremities, face, and earlobes six months after starting the drug. The symptoms became progressively worse as he continued to receive this medication...

Atrial Fibrillation (AF) is the most common cardiac arrhythmia in the world, associated with increased risk of thromboembolic events and an increased mortality rate. In addition, a significant portion of AF patients are asymptomatic. Current AF diagnostic methods, often including a body surface electrocardiogram or implantable loop recorder, are both expensive and invasive and offer limited access within the general community. Objective We tested the feasibility of the detection of AF using photoplethysmographic signal acquired from an inexpensive, non-invasive earlobe photoplethysmographic sensor...
