Actinic lichen planus is a particular subtype of lichen planus with a distinct photodistribution. This disease has been variously named lichen planus in subtropical countries, such as lichen planus subtropicus annularis, lichen planus tropicus, summertime actinic lichenoid eruption, and lichenoid melanodermatitis. It is a disorder seen most frequently in Africa, the Middle East, and the Indian subcontinent, favoring Asiana. This disease presents in the spring or summer and is frequently quiescent during the winter. A 61-year-old man with unusual lichenoid photosensitive eruption is presented. The lesions developed during the late spring, appearing on both dorsa of hands, wrists, and lower legs. We report a case of actinic lichen planus with a review of the literature.

We report a case of type IIa hyperlipoproteinemia with xanthoma tendinosum associated with coronary artery disease in a 51 year-old male. Multiple hard nodules appeared firstly on both achilles tendon area 30 years ago and the lesions gradually spread to the dorsa of hands and feet. On past history, he had been diagnosed as unstable angina with atherosclerosis of three vessels in coronary arteries, 2 years ago. His family history revealed nothing contributory. Serum lipid profile including lipoprotein electrophoresis showed an increase in total cholesterol and LDL-cholesterol with increased P-lipoprotein fraction, which suggested type IIa hyperlipoproteinemia. Histopathologic finding of a nodule from the dorsum of right hand showed many foamy histiocytes and cholesterol clefts in the dermis. Most of the xanthoma cells were mononuclear, but many Touton type giant cells were seen also. He died suddenly of heart failure with unstable angina. (Korean J Dermatol 2003;41(11) : 1541-1543)

Decompression sickness is divided into 2 types based on clinical symptoms and severity. Type I decompression sickness involves usually the musculoskeletal system and cardiopulmonary system. Type II decompression sickness involves commonly the central nervous system. We experienced a case of type II decompression sickness involving cervical spinal cord. The patient showed hypesthesia below C5 dermatome and quadriplegia. But the whole spinal magnetic resonance image revealed high signal of the spinal cord below T2 levels and electrodiagnostic study showed thoracic cord level lesion. In decompression sickness, diagnosis of injured spinal cord levels is very delicate problem because in some cases clinical symptoms can be unmatched with magnetic resonance findings and electrodiagnostic study. In this kind of case there are little studies of diagnostic tools and prognostic factors. Therefore, focusing on clinical symptoms need to help more proper treatment and provide better prognosis to decompression sickness patients

Backgrounds : In almost stroke patients, dysphagia is improved with rehabilitation therapy. But, it is not identified the relationship between dysphagia and physical function recovery in stroke patients. Methods : A total of 21 patients with stroke-caused swallowing disorders based on a videofluoroscopic swallowing study (VFSS) were examined swallowing function and physical function at admission and after treatment for 4 weeks (including Vitalstim). Swallowing function was evaluated by the functional dysphagia scale (FDS) using VFSS before treatment and after treatment. Physical function was evaluated by the motricity index (MI) and modified barthel index (MBI) at admission and after 4 weeks. And the relationship between dysphagia and physical function recovery was evaluated. Results : After treatment for 4 weeks, total score, residue in oral cavity, oral transit time, laryngeal elevation and epiglottic closure, residue in valleculae, residue in piriform sinus, coating of pharyngeal wall after swallow were significantly decreased in FDS (p<0.05). There were a significant improvement in MBI (p<0.05) and the correlation between FDS and MBI. But, MI was not showed correlation with FDS. Conclusions : There was relationships between swallowing function improvement and recovery of physical function in almost FDS factors.

A 59-year-old man with history of diabetes mellitus presented to the emergency department with chest discomfort and pain. On admission, electrocardiogram revealed low voltage and ST-segment elevation (II, II aVF). Chest x-ray showed marked cardiomegaly. Laboratory test revealed leukocytosis (23.12 x10^9/L), elevated serum C-reactive protein (CRP): 16.84 mg/dL). The cardiac markers (CK-MB, TnI) were normal range but pro-BNP was elevated (9263.8 pg/mL). Echocardiogram showed rupture of the left ventricular apex with larged pericaridial effusion (Fig.1). Chest computed tomography revealed large left ventricular aneurysm with rupture in the anteroinferior wall and associated hemopericardium (Fig.2). The patient underwent emergency cardiac surgery. There was large amount of prulent pericardial effusion and detection of Streptococcus pneumoniae in culture of pericardial effusion. It was successfully repaired surgically and the patient received antibiotics management. Patient``s symptom was improved and the patient made a good recovery. We report uncommon case of left ventricular free wall rupture caused by Streptococcus pneumonia pericarditis.

2023년 기준 서울시 건축물의 20.1%가 건축법 발효 전 내진설계가 되지 않아 사회적인 문제로 대두되고 있다. 이를 바탕으로 지진에 대한 피해를 사전에 방지할 수 있도록 균열제어성능, 에너지 흡수, 인성능의 특성을 발현하는 고인성 복합체로 압축강도, 됨강도, 직접인장변형률, 열전도율, 단위중량, 길이변화율, 내구성지수를 평가해 고인성 복합체가 건축물의 내진 성능에 적합한지를 확인하고자 위 실험을 진행하였다. 성능평가 결과, 고인성 복합체의 특성이 내진 성능 향상에 도움을 줄 수 있을 것으로 판단된다

The Cut off type progressive die for U-bending production part is a very specific division. This study reveals the sheet metal forming process with multi-forming die by Center Carrier type feeding system. Through the FEM simulation by DEFORM, it was accepted to u-bending process as the first performance to design of strip process layout. The next process of die development was studied according to sequence of die development, i.e. die structure, machining condition for die making, die materials, heat treatment of die components, know-how and so on. The feature of this study is the die development of scrapless progressive die of multi-stage through the Modeling on the I-DEAS program, components drawing on the Auto-Lisp, CAD/CAM application, ordinary machine tool operating and revision by tryout.

<P>This study compared clinical outcomes of drug-eluting stents (DES) versus bare-metal stents (BMS) in large coronary arteries in patients with acute myocardial infarction (MI). A total of 985 patients who underwent single-vessel percutaneous coronary intervention (PCI) in large coronary arteries (≥ 3.5 mm) in lesions < 25 mm were divided into DES group (n = 841) and BMS group (n = 144). Clinical outcomes during 12 months were compared. In-hospital outcome was similar between the groups. At six months, death/MI rate was not different. However, DES group had significantly lower rates of target-lesion revascularization (TLR) (1.7% vs 5.6%, <I>P</I> = 0.021), target-vessel revascularization (TVR) (2.2% vs 5.6%, <I>P</I> = 0.032), and total major adverse cardiac events (MACE) (3.4% vs 11.9%, <I>P</I> = 0.025). At 12 months, the rates of TLR and TVR remained lower in the DES group (2.5% vs 5.9%, <I>P</I> = 0.032 and 5.9% vs 3.1%, <I>P</I> = 0.041), but the rates of death/MI and total MACE were not statistically different. The use of DES in large vessels in the setting of acute MI is associated with lower need for repeat revascularization compared to BMS without compromising the overall safety over the course of one-year follow-up.</P>
