Saving the outer ear in burn injuries is a challenging task for the treating surgeon that should not be underestimated. Burns which are initially evaluated as superficial, particularly in this region, often have a tendency to undergo progressive tissue destruction whereby conservative treatment is often no longer sufficient to preserve the skin of the auricle with the underlying cartilage. Various possibilities for saving the ear and for ear reconstruction are described, but in the case of severely burned patients it is often necessary to carry out a quick and relatively simple treatment...

The sclerotized structures of monogeneans have traditionally been studied by light microscopy and different staining techniques. Recently, enzymatic digestion followed by scanning electron microscopy (SEM) has enabled the examination of structural details not visible with light microscopy. In order to obtain better, and more accurate, morphological information on sclerotized structures not affected by mounting medium or cover slip pressure, the sclerites of Cichlidogyrus philander Douëllou, 1993 (Monogenea, Ancyrocephalidae), collected from Pseudocrenilabrus philander (Weber, 1897), were redescribed using SEM...

A 78-year-old man had fever, persistent wheezing, and serum C-reactive protein elevation. Malignant lymphoma was suspected because of mediastinal lymph nodes swelling on CT and soluble interleukin 2 receptor elevation. Symmetric F-FDG uptake in the tracheobronchial tree and bilateral auricles was observed on PET/CT. He was finally diagnosed as having relapsing polychondritis by auricular cartilage biopsy. F-FDG PET/CT may have crucial role in evaluating the extent of inflammation and deciding the biopsy site of relapsing polychondritis...

We developed a surgical technique to correct cryptotia using a subcutaneous pedicled flap raised from the retroauricular region. A skin paddle over the caudal part of the auricular sulcus is designed and transferred to the skin defect of the upper posterior surface of the auricle. This procedure has been performed on 17 ears in 14 patients with cryptotia since 1992. There were no postoperative complications, such as necrosis of the flaps or deformities, and cryptotia did not recur in any patient. A satisfactory auricular contour with a sufficiently deep auriculotemporal sulcus was preserved in all cases...

The objective of the present study was to evaluate the possibility of the application of the cyanoacrylate-based glue for the strengthening of the reconstructed elements of the middle ear and its influence on the regeneration of the cartilaginous tissue. We used the cartilaginous tissue from the auricles of the male California rabbits as a model. The cartilage was destroyed in a standard press. Half of the cartilage thus fragmented was implanted into the left auricle. The remaining part was mixed up with the cyanoacrylate glue and implanted into the right auricle of the same animal...

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...

Background: The great auricular nerve (GAN) provides sensory innervation to the skin around the auricle. Although disorder of this nerve has been reported, great auricular neuralgia, as reported by Blumenthal in 1992, is uncommon. The authors report a case of auricular paresthesia that responded well to electroacupuncture treatment (EAT). Case: A man in his 60s was consulted in the clinic after a 6-month history of experiencing tingling sensations of the skin around the auricle. General degenerative deformity of the cervical spine was observed using computed radiography scans and magnetic resonance imaging; tactile hyperesthesia in the skin of the GAN area was also noted...

Objective: Pathology of an internal organ/body part changes electrical features of the corresponding skin areas-organ projection areas (OPAs)-which are often identified with traditional acupuncture points/zones. Once the resistance "breakthrough effect" has been induced in these specific skin areas, rectification of applied electrical currents (a diode phenomenon) occurs. In addition, increased impedance can be observed. It is presumed that these skin bioelectrical phenomena are the result of increased local capillary permeability with extravasation of blood-plasma albumins...

INTRODUCTION: The issue on the mode of blood motion in the bloodstream, where the arterial and venous flow is significantly different, has been of greater concern recently. However, the conclusions are largely based on the analysis of the geometric orientation in the wall of arteries of smooth muscle elements. The aim of our study was to examine the characteristics of the prominent configuration of cardial cavities and arterial vessels. MATERIALS AND METHODS: The material for study were specimens of human heart, rabbit aorta and arterial microvessels of rat salivary glands, examined by injection and corrosive methods, scanning and transmission electron microscopy...

Congenital heart disease (CHD) is the most frequent birth defect. RCAN1 (regulator of calcineurin 1) contributes to CHD in Down syndrome. However, whether RCAN1 is also associated with nonsyndromic CHD remains unclear. This study sequenced the exons and flanking region of RCAN1 in 128 sporadic CHD patients and 150 normal controls. We identified six novel heterozygous mutations in CHD patients. Functional assay showed that the g.482G>T could obviously raise the promoter activity of RCAN1.4 in vitro; However, we failed to detect the expression of RCAN1 in the right auricle, which made it confused to evaluate the pathogenicity of this mutation...
