Clinical Characteristics of Odontogenic Cutaneous Fistulas

Eun-Young Lee, Ji-Yeon Kang, Kyung-Won Kim, Ki Hwa Choi, Tae Young Yoon, Ji Yeoun Lee
2016 Annals of Dermatology  
Odontogenic cutaneous fistula appears as dimpling or a nodule with purulent discharge, usually in the chin or jaw. Affected patients usually seek help from dermatologists or surgeons rather than from dentists. However, clinical symptoms of facial skin fistula without dental problems can lead to misdiagnosis. Objective: The purpose of this study was to investigate the clinical characteristics of patients with odontogenic cutaneous fistulas. Methods: This retrospective observational study was

Following clinical and radiographic examinations, the paths and origins of sinus fistulas were determined. Investigated factors were gender, age, morphology, location, originating tooth, time to evolution, recurrence, and treatment method. Results: Thirty-three patients (22 males, 11 females; average age 49.2 years) were examined during the investigation period. Thirty-four fistulas were diagnosed as odontogenic cutaneous fistulas. The most common morphology was dimpling (n=14, 41.2%). The various locations observed were related to the originating tooth. The most common site was the mandibular body related to mandibular molars. The referral clinical diagnosis was of odontogenic origin in 6 cases (18.2%). The majority of patients had experienced recurrence after treatment in previous clinics that had failed to diagnose odontogenic cutaneous fistula. Surgical fistulectomy and/or tooth treatment were performed in all cases. All patients were followed-up for 1 year. None showed signs of recurrence. Conclusion: Extraoral and dental examinations are required to make a diagnosis of odontogenic cutaneous fistula. Thus, cooperation between dermatologists and dentists is essential.

A Case of Post-Traumatic Pulmonary Pseudocyst Mimicking Pulmonary Cavitary Tuberculosis

Hyun Jeong Lee, Ji Young Kang, Sun Mie Yim, Eun Hye Ji, Ji Hyun Kim, Sei Won Kim, Sang Haak Lee, Hwa Sik Moon, Bae Young Lee
2009 Tuberculosis and Respiratory Diseases  
A traumatic pulmonary pseudocyst is a rare complication of blunt thoracic trauma. The clinical symptoms and signs are similar to other respiratory diseases, such as pulmonary tuberculosis. Therefore, a trauma history with the resulting radiologic and clinical findings is important for making a diagnosis. A 26-year-old male was admitted to our hospital due to cough for 3 days. The chest x-ray revealed diffuse infiltrations and a cavitary lesion at the left lung. His left chest had hit a tree as

However, bronchoscopy revealed old blood clots at both lungs, particularly in the left lower lobe bronchus. A transbronchial lung biopsy showed alveolar hemorrhage. A traumatic pulmonary pseudocyst was diagnosed from his trauma history and these findings. Computed tomography of the chest performed 4 months later showed regression of the cavitary lesion.

Leflunomide-induced Toxic Epidermal Necrolysis in a Patient with Rheumatoid Arthritis

Ji Hye Je, Hyun Jung Lee, Young Ju Na, Ji Hye Seo, Young Ho Seo, Jae-Hoon Kim, Sung Jae Choi, Young Ho Lee, Jong Dae Ji, Gwan Gyu Song
2014 Journal of Rheumatic Diseases  
Leflunomide was licensed for the treatment of rheumatoid arthritis in 1998 and has been available in Korea since 2003. Allergic cutaneous reactions (rash, purpura) are common (<10%) side effects of leflunomide, but severe cases such as Stevens-Johnson syndrome (SJS) or toxic epidermal necrolysis (TEN) are rarely reported. There has not been a report of SJS or TEN induced by leflunomide in Korea. Here we report a case of leflunomide-induced TEN in a patient with rheumatoid arthritis. Leflunomide

Cu Mesh for Flexible Transparent Conductive Electrodes

Won-Kyung Kim, Seunghun Lee, Duck Hee Lee, In Hee Park, Jong Seong Bae, Tae Woo Lee, Ji-Young Kim, Ji Hun Park, Yong Chan Cho, Chae Ryong Cho, Se-Young Jeong
2015 Scientific Reports  
Copper electrodes with a micromesh/nanomesh structure were fabricated on a polyimide substrate using UV lithography and wet etching to produce flexible transparent conducting electrodes (TCEs). Well-defined mesh electrodes were realized through the use of high-quality Cu thin films. The films were fabricated using radio-frequency (RF) sputtering with a single-crystal Cu target-a simple but innovative approach that overcame the low oxidation resistance of ordinary Cu. Hybrid Cu mesh electrodes

The sheet resistance and the transmittance of the electrode with an Al-doped ZnO capping layer were 6.197 ohm/sq and 90.657%, respectively, and the figure of merit was 60.502 × 10 -3 /ohm, which remained relatively unchanged after thermal annealing at 200 °C and 1,000 cycles of bending. This fabrication technique enables the mass production of large-area flexible TCEs, and the stability and high performance of Cu mesh hybrid electrodes in harsh environments suggests they have strong potential for application in smart displays and solar cells. Transparent conducting electrodes (TCEs), which have high optical transparency and high electrical conductivity, are widely used in numerous optoelectronic devices, including organic/inorganic light-emitting diodes, liquid-crystal displays, touch-screen panels, supercapacitors, and solar cells 1-7 . Historically, the use of indium tin oxide (ITO) has dominated in the TCE industry; however, some critical problems are associated with the mechanical, thermal and chemical stability of ITO. The scarcity of indium and its increasing price are additional factors that make ITO undesirable in TCE applications. Thus, efforts have been devoted to the development of alternatives to ITO (e.g., conducting polymers, Al-doped ZnO and metal thin films); however, these alternatives have been unsatisfactory for industrial demands 8-10 . In recent years, however, micromaterials and nanomaterials, including carbon nanotubes, graphene, and metal wire/particle networks, have offered a new paradigm for the TCE industry 11-20 . Among these, metal nanostructure network TCEs have exhibited high performance and are suitable for large-area applications. Various fabrication methods have been employed, such as spin (or spray) coatings of nanowire dispersions 11-17 , electronic spinning 17-19 , and lift-off processes with nanotemplates 21-23 . Silver (Ag), in particular, has attracted great interest for TCE applications because of its superior electrical conductivity, and various fabrication processes have been investigated to simplify the manufacturing process and to improve performance 4, [13] [14] [15] [16] [17] [18] [20] [21] [22] . However, Ag is not suitable for use in mass production requiring low costs. Copper (Cu) has high electrical conductivity comparable to that of Ag, and Cu is much less expensive and more abundant than Ag 11,23 . Recently, transparent conductive films have been reported

The levels of hemoglobin (HB), hematocrit (HCT), and creatinine (CR), were elevated when a high-intensity physical activity was performed, but they were reduced when a low-intensity physical activity was performed in the normal group aged 10∼29 years and the metabolic disease group aged 50∼69 years. In the normal group and metabolic disease group aged 30∼49 years, the level of high density lipoprotein cholesterol (HDL-C) was elevated when high-intensity physical activity was conducted, whereas it was reduced when low-intensity physical activity was performed. No difference in the level of HDL-C depending on age and exercise intensity was observed in the normal group; the level of HDL-C decreased with age and increased with exercise intensity in the metabolic disease group. Physical activity has different effects in metabolic disease depending on age.
