Purpose To compare the MR findings of septic and acute gouty arthritis of the knee joint. Materials and Methods This retrospective study included patients who underwent knee MRI for septic or gouty arthritis at our hospital between October 2012 and October 2018. The MR findings were analyzed for the presence of bone marrow edema, soft tissue edema, abscess, pattern of synovial thickening (frondlike, lamellated, diffuse linear), maximum thickness of the synovium, and joint effusion volume. The gouty (n = 5) and septic arthritis (n = 10) groups were compared using the Wilcoxon rank-sum test and Fisher's exact test. Results No statistically significant differences were observed for each item. One patient in the gouty arthritis group and seven in the septic arthritis group had bone marrow edema. Soft tissue abscess formation was only observed in the septic group. The incidence of each synovial thickening pattern was as follows: 100% (diffuse linear) in the gouty arthritis group and 20% (frondlike), 50% (lamellated), and 30% (diffuse linear) in the septic arthritis group. Conclusion Differentiation of gouty arthritis and septic arthritis based on imaging findings is difficult. However, lamellated synovial thickening patterns, bone marrow edema, and soft tissue abscess formation are more commonly observed in patients with septic arthritis than in those with gouty arthritis.

Recently arthroscopic procedure was introduced into an effective method when chronic gouty arthritis associated with acute inflammation is unresponsive to conservative treatment. The purpose of this study is to cvaluate the efficacy of tophi excision during this procedure. We tried to excise tophi which were known as one of causative materials of acute inflammation as much as possible. We report one case of chronic tophaceous gouty arthritis of the right knee which was satisfactorily treated without recurrence during more than one year after this arthroscopic procedure.

A 67-year-old male patient with a history of epididymectomy and anti-tuberculosis treatment for epididymis tuberculosis was admitted for acute low back pain and radiating pain. The patient had no history of gout but showed hyperuricemia and a bone destruction lesion in the facet joint and lamina of the lumbar spine. A histology examination was performed after a computed tomography-guided needle biopsy, and the findings were compatible with gout spondyloarthropathy and tuberculous spondylitis. The acute symptoms improved after conservative treatment for gouty arthritis. When patients with hyperuricemia risk factors, such as taking anti-tuberculosis drugs, complain of acute low back pain, gout spondyloarthropathy should be considered in a differential diagnosis.

관절염은 관절에 염증을 일으키는 현상을 말하며, 염증이란 병든 부위에 부종, 홍조, 발열, 동통과 같은 병리학적인 반응을 특징으로 한다. 관절염은 그 자체가 병명이 아니고 어떤 질환의 한결과로서 나타난다. 그러므로 관절염이 발생하면 그 원인 질환이 무엇인지 찾아보아야 한다. 관절염의 종류는 무려 100여 가지가 넘으며 퇴행성 관절염, 류머티스 관절염, 통풍성 관절염, 루푸스, 통풍 등이 일반적으로 흔한 종류이다.

Tophaceous gout, which is usually presented in the synovial fluid, bursal lining, cartilage or other soft tissues, may cause a nonoutlet impingement in the rotator cuff and bursa. In chronic tophaceous gout patient with the shoulder pain, a surgeon should consider the possibility of the tophaceous gout of the rotator cuff. We report a surgical experience of a 50-year-old man with tophaceous gout of the rotator cuff causing impingement syndrome. The patient was treated successfully with arthroscopic debridement and subacromial decompression.

대형 전동기의 주요 소음원은 전자기 소음과 냉각/통풍 시스템 소음이며, 이 중 냉각/통풍 시스템이 전체 소음에 큰 영향을 미친다. 본 논문에서는 대형 전동기의 저소음 냉각/통풍 시스템 개발을 위해 저소음 냉각 팬을 개발하고 팬 커버 내부의 유로를 개선하였다. 유동해석은 상용 CFD 소프트웨어를 이용하였으며 팬 커버 내의 scroll 형상 및 air guide, baffle 의 유무에 따라 팬 커버의 압력손실을 계산하였다. 해석을 통해 팬 커버 내부의 난류 유동과 압력손실이 가장 작은 팬 커버 형상을 도출하였으며 개선된 냉각/통풍 시스템이 기존 냉각/통풍 시스템보다 6.5dB 감소된 것을 확인하였다.

This study was conducted to improve the storability of onion bulbs by assembly simple house storage and the reduce the rotteness caused by field open storage. Allium cepa cv. Changnyungdeago, late strain was used for the test at the storage condition of natural ventilation of levels 2, forced ventilation of levels 2, field open storage and 75mm, 100mm, and 125mm ventilating holes. Mean tamperature and relative humidity were not significantly different by ventilation conditions. Mean temperature was lower in forced ventilation than that of in natural ventilation and non-ventilation, and relative humidity was a little higher in ventilation treatment than those of the others. Weight loss of onion bulbs were 2.5%, 2.9%, 3%, 4.3% in field open storage, non ventilation, natural ventilation of levels 2 and forced ventilation of levels 2 respectively. Rotting rate in natural ventilation of levels 2 and farced ventilation of levels 2 were 27.7% and 25.4% respectively but 34.6% and 37.8% in non ventilation and field open storage. Therefore, the treatment of ventilation reduced the rotteness of storage onion bulbs. The smaller the size of a ventilating hole, the lower mean temperature was maintained. The relative humidity was some high in July, but didn’t showed significantly difference in August and September. With small size of a ventilating hole, the strong wind velocity was obtained, and wind velocity by position was weaker in the middle part than both ends. Rutting rates in 75㎜, 100㎜, and 125㎜ ventilating holes were 17.9%, 15.3% and 14.1% respectively.

A diagnosis of gout is often straightforward because gout has well known clinical presentations, laboratory analyses, and radiologic features. On the other hand, gout can mimic other diseases by showing a range of atypical clinical manifestations. This paper reports a 35-year-old male with no prior history of gout who developed tophaceous gout at his previously repaired Achilles tendon 11 years after surgery. He was initially misdiagnosed with cellulitis because of his atypical clinical features. This case is presented with a review of the relevant literature.
