INTRODUCTION: There is insufficient evidence to determine if non-invasive transcutaneous bilirubin (TcB) measurement can replace serum bilirubin (SBR) in assessing rebound hyperbilirubinaemia after phototherapy. OBJECTIVE: To investigate if TcB can safely guide management of neonates after phototherapy. SUBJECTS: 100 well neonates ≥35 weeks' gestation who had received inpatient phototherapy. METHOD: Measurement of both helix (manufacturer's recommendation) and earlobe TcB coincidentally with routine SBR 12 hours after cessation of phototherapy...

BACKGROUND: Working memory is essential to a wide range of cognitive functions and activities. Transcutaneous auricular VNS (taVNS) is a promising method to improve working memory performance. However, the feasibility and scalability of electrical stimulation are constrained by several limitations, such as auricular discomfort and inconsistent electrical contact. OBJECTIVE: We aimed to develop a novel and practical method, vibrotactile taVNS, to improve working memory...

BACKGROUND: Keloids are benign proliferative scars that form as a result of dysregulated growth and collagen deposition in response to cutaneous injury. Laser therapies have emerged as promising options for the treatment of keloids, with performance varying by laser type and lesion characteristics. PURPOSE: To assess the combined continuous wave and repetitive fractionated CO2 laser treatment of keloids. METHODS: A retrospective chart review of 22 cases of keloid scars treated with combined CO2 laser modes...

[Purpose] A new wireless laser Doppler blood flowmeter has facilitated easier, more stable measurement of skin perfusion during exercise. However, earlobe blood flow during the cardiopulmonary exercise test remains unascertained. This study aimed to clarify the characteristics of earlobe blood flow during incremental exercise load in healthy individuals. [Participants and Methods] Among 25 healthy males (age 23.6 ± 2.5 years), cycle ergometer-based symptom-limited cardiopulmonary exercise test, after 4 minutes of rest, was conducted with a 4-minute 20W warm-up and a continuous 2W-increase in the work rate every 6 seconds; earlobe blood flow was measured using a wireless laser Doppler blood flowmeter...

Hyperphosphatasia with mental disorder (HPMRS) is a rare autosomal recessive disease caused by gene mutations in enzymes involved in the synthesis and remodeling of lipids. Seven-month-old boy diagnosed with bilateral glaucoma had a cleft palate, facial dysmorphism, hypertelorism, a broad nasal bridge, and large fleshy earlobes. A brain MRI scan also revealed brain abnormalities. The observed phenotype in a seven-month-old boy is in agreement with the phenotypic features of HPRMS type-4. Whole exome sequencing revealed a possible pathogenic variant of PGAP3 in a homozygous state (c...

BACKGROUND: Lobule transposition, a common procedure in auricle reconstruction, has been successfully performed over the past few decades. However, the transposition methods for unilateral microtia with evident asymmetry of bilateral earlobe positions still remain a challenge. The objective of this study was to investigate the application of prograde transposition for anteriorly low-set earlobes. METHOD: A total of 25 patients with lobule-type microtia with anteriorly low-set residual earlobe underwent prograde transposition during auricle reconstruction between 2020 and 2022...

OBJECTIVE: Low-frequency oscillations (LFOs) observed in the periphery may reflect physiological processes. The aim of this study was to investigate these processes' effects on LFOs and the differences between healthy subjects and those with peripheral arteriosclerosis disease (PAD). METHODS: 14 PAD patients and 25 healthy controls were studied in resting (RS) and passive leg raising (PLR) states. We simultaneously measured LFOs at the peripheral left earlobes (LE), right earlobes (RE), left fingertips (LF), right fingertips (RF), left toes (LT), and right toes (RT), along with coherence and phase shift analysis processing...

Because the auricle plays an important role in facial aesthetics, all earlobe operations must seek to limit postoperative ear deformity. This report describes the single-stage posterior-auricle bilobed cartilage-skin flap technique for reconstructing the earlobe. A 31-year-old man incurred a left earlobe deficiency due to a human bite. Earlobe reconstruction was conducted 102 days later. A bilobed flap was designed on the posterior-auricular skin. Both flaps were pedicled in the caudal posterior-auricular area...

Earlobes, nasal cavities, and fingers of 145 healthcare workers in convalescent and rehabilitation hospital (60 nurses and 85 rehabilitation healthcare workers) were sampled. Of the 3 sites sampled, Staphylococcus aureus was detected in one or more sites in 25 nurses and 27 rehabilitation workers. S. aureus was detected in all 3 sites in 2 (8.0%) nurses and 2 (7.4%) rehabilitation workers, and the S. aureus isolates in each case showed related PFGE pattern. S. aureus was detected in both the fingers and nasal cavities of 5 (18...

A 27-year-old male with no significant past medical history presented with recurrent swelling and pain on the right superior crus of the antihelix initially misdiagnosed as a skin infection. Despite adherence to antibiotic treatment, his condition showed no improvement, leading to further investigation. The patient's detailed clinical examination, family history devoid of autoimmune disorders, and persistent auricular inflammation prompted a reconsideration of the diagnosis. A subsequent biopsy that captured cartilage revealed auricular chondritis, perichondrial inflammation, degeneration of cartilage, and infiltration by inflammatory cells, all of which have been clinically associated with relapsing polychondritis (RP)...

Neonatal suppurative parotitis is a rare condition that is diagnosed primarily through clinical evaluation. The prognosis is generally good. In this report, we present the case of a 21-day-old female infant who was treated in our ENT department for neonatal suppurative parotitis. The patient presented with a feverish, hard, red, and tender swelling of the parotid loge which displaced the right earlobe outward. In addition, purulent exudate was observed from Stensen's duct. A computed tomography scan of the cervical and cerebral regions revealed a swollen right parotid gland with heterogeneous density and enhancement, but no detectable collection...

The aim of this study was to clarify the effects of transcutaneous auricular vagus nerve stimulation (taVNS) to the left cymba concha on the pain perception using nociceptive withdrawal reflex (NWR), which is known to be associated with chronic pain, and to investigate whether there is a relationship between taVNS-induced suppression of the NWR and parasympathetic activation. We applied either 3.0 mA, 100 Hz taVNS for 120 s on the left cymba concha (taVNS condition) or the left earlobe (Sham condition) for 20 healthy adults...

BACKGROUND: Lung cancer (LC) is the leading cause of malignancy-related deaths worldwide. The most common sites of metastasis include the nervous system, bone, liver, respiratory system, and adrenal glands. LC metastasis in the parotid gland is very rare, and its diagnosis presents a challenge. Here, we report a case of parotid metastasis in primary LC. CASE SUMMARY: The patient was a 74-year-old male who was discovered to have bilateral facial asymmetry inadvertently two years ago...

Background Transcutaneous carbon dioxide tension (PtcCO2 ) measurement is a promising alternative to arterial carbon dioxide tension (PaCO2 ) measurement. PaCO2 measurement is invasive and intermittent, whereas PtcCO2 measurement is non-invasive and continuous. However, previous studies evaluating PtcCO2 measurements did not include patients undergoing transcatheter aortic valve replacement (TAVR), who experience anticipated hemodynamic changes, particularly before and after valve placement. Therefore, we investigated whether PtcCO2 measurement could provide an alternative to PaCO2 measurement during transfemoral TAVR under monitored anesthesia care (MAC) with local anesthesia...

BACKGROUND: Protruding ears are the most common auricular abnormalities seen in children (1). Protruding ears are a condition that has social and psychological consequences due to its physical appearance and one of the main causes of peer bullying at young ages (2). While various surgical methods exist to address prominent ears, the options for correcting the lobule are relatively scarce. In this study, we are aimed to present the modified fish-tail technique that we have developed and to compare it with other techniques in the literature...

BACKGROUND: Since 2010, several cases of a new vasculopathy induced by the use of levamisole-adulterated cocaine (LAC) have been reported. This vasculopathy is characterized by retiform purpura, earlobe necrosis, multisystem compromise, and multiple autoantibodies. Given its similarity to antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis, LAC-associated vasculopathy is postulated to be mediated by pathophysiologic processes resulting from neutrophil cell death by NETosis, a phenomenon previously described in ANCA vasculitis...

Twenty-one morphometric traits were measured on 770 extensively managed indigenous chickens in the western zone of Tigray, comprising 412 hens and 358 cocks in three agro-ecologies. The quantitative traits for male and female chicken ecotypes were separately analyzed using multivariate analysis with SAS 2008. Four and seven principal components accounted for about 74.26% and 69.77% of the total variability in morphometric traits for males and females, respectively. Earlobe length, wingspan, skull length, and shank length werethe most important traits for discriminating among female chicken ecotypes, while wingspan, neck length, earlobe length, spur length, body length, and shank length were the most important discriminatory traits among male chicken ecotypes...

BACKGROUND: In 1973, Saunders T. Frank described the diagonal earlobe crease (DELC) as a potential marker of cardiovascular disease. However, this anatomical finding is not routinely examined. The aim of this study was to assess the presence of this crease in the general population attending a dental setting and describe its anatomical variations to be able to categorize it as a physical sign. METHODOLOGY: A study group of 1050 white adults were selected, as participants in the framework of the "A Estrada Study of Glycation and Inflammation" (AEGIS), a cross-sectional, population-based descriptive study of a representative sample of the general adult population of the municipality of A Estrada (Pontevedra, Spain)...
