Development of spider veins is caused by the remodeling of veins located in the upper dermis and promoted by risk factors such as obesity or pregnancy that chronically increase venous pressure. We have repeatedly shown that the pressure-induced increase in biomechanical wall stress is sufficient to evoke the formation of enlarged corkscrew-like superficial veins in mice. Subsequent experimental approaches revealed that interference with endothelial- and/or smooth muscle cell (SMC) activation counteracts this remodeling process...

BACKGROUND: Auricular reconstruction is one of the most challenging procedures in the field of plastic surgery. The aims of this study were to apply the modified 2-stage method to perform auricular reconstruction and to summarize the clinical experience in the past 10 years. METHODS: Auricular reconstruction was performed in 243 patients (total 254 ears) of congenital microtia using autologous costal cartilage. The whole procedure is divided into 2 stages. Stage I: the individualized framework fabricated with autologous costal cartilage is inserted into subcutaneous pocket in the mastoid region, and then the earlobe was transposed backward to connect with the lower part of the framework...

Arterial thromboembolism is a life-threatening condition in cats most commonly secondary to cardiac disease. Echocardiography is the reference standard to evaluate for presence of a thrombus. In humans, computed tomographic (CT) angiography is becoming widely used to detect left atrial thrombi precluding the use of sedation. The purpose of this prospective, controlled, methods comparison pilot study was threefold: (1) describe new CT angiography protocol used in awake cats with cardiac disease and congestive heart failure; (2) determine accuracy of continuous and dynamic acquisition CT angiography to identify and characterize cardiac thrombi from spontaneous echocardiographic contrast using transthoracic echocardiography as our reference standard; (3) identify known negative prognostic factors and comorbidities of the thorax that CT angiography may provide that complement or supersede echocardiographic examination...

Reconstruction of a facial defect is a complex modality either surgically or prosthetically, depending on the site, size, etiology, severity, age, and the patient's expectation. The loss of an auricle, in the presence of an auditory canal, affects hearing, because the auricle gathers sound and directs it into the canal. The auricle acts as a resonator to slightly amplify lower frequency sounds and helps to localize sounds, especially in conjunction with the other ear. Osseointegrated implants have an important role in the prosthetic reconstruction of patients with craniofacial defects...

BACKGROUND: Nagata's two-stage technique for microtia reconstruction using autologous costal cartilage consists of the implantation of a fabricated cartilage framework and the elevation of the constructed auricle. Achieving long-lasting, sufficient projection of the auricle is a goal of second-stage surgery; however, unfavorable outcomes have been seen in some patients, with suboptimal long-term elevation. The present study aimed to investigate prognostic factors that might contribute to adverse outcomes following the ear elevation operation...

OBJECTIVE: In advanced temporal bone carcinoma cases, we attempted to preserve as much of the auricle as possible from a cosmetic and functional perspective. Difficulties are associated with selecting an adequate position for reconstructed auricles intraoperatively. We improved the surgical procedure to achieve a good postoperative auricle position. METHODS: Nine patients were included in this study. All patients underwent subtotal removal of the temporal bone and resection of the external auditory canal while preserving most of the external ear, and lateral skull base reconstruction was performed with anterolateral thigh flaps...

Anther development progresses through 15 distinct developmental stages in wheat, and accurate determination of anther developmental stages is essential in anther and pollen studies. A detailed outline of the development of the wheat anther through its entire developmental program, including the 15 distinct morphological stages, is presented. In bread wheat ( Triticum aestivum ), anther developmental stages were correlated with five measurements, namely auricle distance, spike length, spikelet length, anther length and anther width...

Lungfishes are the closest living relatives of land vertebrates, and their neuroanatomical organization is particularly relevant for deducing the neural traits that have been conserved, modified, or lost with the transition from fishes to land vertebrates. The immunohistochemical localization of calbindin (CB) and calretinin (CR) provides a powerful method for discerning segregated neuronal populations, fiber tracts, and neuropils and is here applied to the brains of Neoceratodus and Protopterus, representing the two extant orders of lungfishes...

Paramount for the generation of auricular structures of clinically-relevant size is the acquisition of a large number of cells maintaining an elastic cartilage phenotype, which is the key in producing a tissue capable of withstanding forces subjected to the auricle. Current regenerative medicine strategies utilize chondrocytes from various locations or mesenchymal stromal cells (MSCs). However, the quality of neo-tissues resulting from these cell types is inadequate due to inefficient chondrogenic differentiation and endochondral ossification, respectively...

We describe a unique presentation of a rare disease presentation of a granular cell tumour. A 36-year-old woman presents with a large symptomatic left flank mass that had been slowly increasing in size. Multiple synchronous subcutaneous masses were found at presentation on the left breast, right auricle and right cheek. After diagnosis of granular cell tumour by core needle biopsy, the masses were excised with histopathological and immunohistochemical analysis of both specimens confirming the presence of non-malignant granular cell tumours...

BACKGROUND: Rothmund-Thomson syndrome (RTS) is a rare autosomal recessive disorder mainly characterized by cutaneous poikiloderma, sparse hair, short stature and skeletal defects. Deleterious mutations in the RecQ-like DNA helicase type 4 (RECQL4) gene have been detected in approximately two-thirds of RTS cases. METHODS: Three Chinese patients from two unrelated families were enrolled for clinical evaluation. Targeted next-generation sequencing (NGS) using a custom panel consisting of 705 short-stature-related genes was performed for the probands...

Fibroepithelioma of Pinkus (FEP) is traditionally classified as an unusual variant of basal cell carcinoma. It has non-specific clinical findings yet distinct histologic features. The diagnosis can be challenging for clinicians because it often mimics benign entities such as intradermal nevi. FEP typically occurs on the trunk, but many body sites can be involved including the head, neck, and genitalia. According to a PubMed search of articles indexed in MEDLINE using "Fibroepithelioma of Pinkus" and "ear" or "auricle," there are no reports of FEP specifically occurring on the ear...

OBJECTIVE: Auricular elevation with superficial temporal fascia and skin graft is widely used in microtia reconstruction using costal cartilage. However, in some patients, there has been occurrence of contraction of skin graft, which led to insufficient projection of the elevated auricle and diminished auriculocephalic angle with unfavorable long-term results. In this article, the authors introduce their multiple triangular flaps with zigzag incision to maintain stable projection and natural retroauricular sulcus appearance in auricular reconstruction patients...

BACKGROUND: Fibromyalgia is a chronic pain state that includes widespread musculoskeletal pain, fatigue, psychiatric symptoms, cognitive and sleep disturbances, and multiple somatic symptoms. Current therapies are often insufficient or come with significant risks, and while there is an increasing demand for non-pharmacologic and especially non-opioid pain management such as that offered through complementary and alternative medicine therapies, there is currently insufficient evidence to recommend these therapies...

Accessory auricles are relatively rare malformations arising from the first branchial arch which contains skin, fat and cartilage. The treatment is usually surgical removal for the cosmetic purpose. We are sharing our experience of utilising the accessory auricle skin as full thickness graft for post.burn reconstruction of the fingers contracture of a child. Even though this type of association is rare, it is an innovative idea following Sir Harold Gilles' principle 'Never throw anything away'.

Microtia is a congenital external ear malformation that can seriously influence the psychological and physiological well-being of affected children. The successful regeneration of human ear-shaped cartilage using a tissue engineering approach in a nude mouse represents a promising approach for auricular reconstruction. However, owing to technical issues in cell source, shape control, mechanical strength, biosafety, and long-term stability of the regenerated cartilage, human tissue engineered ear-shaped cartilage is yet to be applied clinically...

Diagonal ear lobe creases, often known as Frank's sign, are a folding in the skin of the ear lobe. Many studies have found an association between diagonal ear lobe creases and coronary artery disease. To our knowledge, this is the first report of paired ear creases of the helix. They may have similar relevance to cardiovascular disease as the diagonal ear lobe creases. We report the case of a 68-year-old South Asian man with coronary artery disease and a diagonal ear lobe crease. On closer inspection of the auricle, he also had ear creases on the helix on the same side...

BACKGROUND: Attaining an ideal appearance of the reconstructed ear depends primarily on the fabricated cartilaginous ear framework. Despite the role of eighth costal cartilage, the length of the eighth rib cartilage is difficult to anticipate, and growth of the eighth cartilage is variable. The authors discussed modified methods of fabricating helix and antihelix based on different length of eighth costal cartilage. METHODS: Based on the actual length of the eighth costal cartilage, patients were divided into group A and group B...
