  • Objectives: Tsutsugamushi disease is one of the most significant acute febrile illnesses, increasing in frequency of occurrence during the late autumn in rural areas of Korea. Methods: I have conducted a case-control study on 30 cases who had the fever as a chief complaint, then had been ruled out as having the Tsutsugamushi disease. Data was collected retrospectively by review of chart regarding their general characteristics, clinical and laboratory findings, then was analysed by chi-test. Results: Of 30 cases, 16 cases were seropositive and 14 cases were seronegative against O. tsutsugamushi. Of seropositive for tsutsugamushi disease, 56.3% were female; 37.5% were in their seventies; 50.0% were farmers; 62,6% had chances of exposure to fields or mountains. And 75.0% occurred in November. The main symptoms and signs were fever and chill(100.0%), headache(75.0%). weakness and fatigue(93.8%), and eschar(68.8%). The characteristic laboratory findings were elevated AST(50.0%), ALT(62.5%), and abnormal urinalysis(56.3%). On the other hand, of seronegative cases, 57.1% were male; 50.0% were in their fifties; 42.9% were farmers; 57.2% had chances of exposure to fields or mountains. And 71.4% occurred in November. The symptoms and signs were fever and chill(100.0%), headache(85.7%), eschar(64.3%). weakness, fatigue and skin(57.1%). The laboratory findings were elevated AST(71.4%) and ALT(64.3%), and abnormal urinalysis(42.9%). However, there were no significant differences between the seropositive and seronegative cases(P>.05). Conclusions: Acute febrile community inhabitants who have the epidemiological, clinical as well as laboratory features should be focused upon for the early diagnosis and treatment for tsutsugamushi disease whether or not possessing the serological antibody against O. tsutsugamushi.

  • There could be several methods for trochanteric reconstruction including local flap, pedicled perforator flaps, free flap, etc. We performed greater trochanteric reconstruction with lumbar artery perforator free flap in some aberrant method. So we report this experience with review of literatures. A 42-year-old man visited our hospital with a large soft tissue defect in his left greater trochanteric area by traffic accident. The patient had wide skin and soft tissue defect combined with open femur fracture. During one month period of admission, he underwent femur open reduction and wound debridement four times. After that we planned thoracodorsal perforator free flap reconstruction. The flap was outlined as large as $20{\times}15\;cm$ and elevated in a suprafascial plane from the lateral border. During intramuscular perforator dissection, we found that two 1.5 mm diametered perforator vessels coursed inferomedially toward second lumbar region. Finally the flap became lumbar artery perforator flap based on second lumbar artery perforator as a main pedicle. After flap transfer, the perforator vessels were connected with inferior gluteal artery and vein microsurgically. The operation was successful without uneventful course. We found no significant postoperative complication and donor site morbidity during six months follow up periods. Lumbar artery perforator flap could be an alternative procedure for thoracodorsal perforator flap in some patients with anatomic variant features.

  • Type 1 diabetes mellitus commonly occurs in childhood and adolescence, although the prevalence of type 2 diabetes mellitus in these age groups is now being increased in the western world and Korea. Diabetic nephropathy developing in 15-25% of subjects with type 1 diabetes mellitus and in similar or higher percentage of type 2 diabetes mellitus patients is the leading cause of end-stage renal disease worldwide. Although prepubertal diabetic duration may contribute less to the development of microvascular complications than pubertal and postpubertal duration, diabetic nephropathy in susceptible patients almost certainly begins soon after disease onset and may accelerate during adolescence, leading to microalbuminuria or incipient DN. Type 1 diabetes is commonly associated with a period of hyperfiltration followed by the development of persistent microalbuminuria after as little as 7-10 years of type 1 diabetes. Microalbuminuria is associated with pathologic lesions that are so advanced as to overlap with those seen in patients with overt proteinuria and declining kidney function, therefore, microalbuminuria currently considered the best clinical indicator of overt diabetic nephropathy risk. This review covers the natural history and renal manifestations of diabetic nephropathy in children and adolescents.

  • This study is to review the printed cotton textile industry of Europe in 17th-l8th century, and specially investigate the development of the Toile do Jouy, printed French fabrics around the 18th century. Generally, the Toile de Jouy has two different meanings. The first meaning is the popular printed cotton textiles producted by wood block printing, copper plate printing and roller printing techniques at Jouy on Joas factory in France, around 18th century. The second meaning is the monochromatic upholstery fabrics printed by copper plate. Actually, this monochromatic printed textiles were the most popular printed cotton fabrics with large scale scenic designs with people, trees, birds, buildings, mythical heroes, protagonists of novel and country scenes of shepherds, sheep and other animals manufactured by Jouy on Joas factory. Main issue of this paper is to propose features of pattern, color and classify types of patterns expressed on the Toile de Jouy fabrics according to printing techniques such as wood block printing, copper plate printing and copper roller printing. And this study is also to analyze on origins of the variety of names called the printed cotton textiles in those days. The results of this study can help to understand the knowledge of printed cotton textiles in Europe and be effectively applied to develop printed fabric design in the textile industry.

  • Spinal neurenteric cyst results from the persistence of an abnormal communication between endodermal and ne-uroectodermal layer. Embryologically, neurenteric cyst is derived from endoderm that is fused with the developing notochord during the third week of gestation. It is a rare malformation that lead to spinal cord compression. The patient is 19-year-old male presented with chest pain, paresthesia and progressive weakness in his low extremities(grade II/II). Preoperative MR imaging revealed intradural extramedullary cyst with intracystic hemorrhage in T1 and T2 level that is ventrally located and compressed the spinal cord. Involved vertebral bodies were scalloped and fused. The cystic tumor were totally removed through costotransversectomy approach. Postoperatively, motor weakness of the low extremities were improved to the level of grade IV/V. And chest pain and paresthesia were gradually disappeared. Postoperative MR imaging showed the decompression of the thoracic spinal cord. Histologic examination revealed a ciliated columnar epithelial neurenteric cyst. The pre- and postoperative clinical, radiological features of a case of upper thoracic neurenteric cyst is described with review of literature.

  • Objective : Although surgical techniques for clipping paraclinoid aneurysms have evolved significantly in recent times, direct microsurgical clipping of large and giant paraclinoid aneurysms remains a formidable surgical challenge. We review here our surgical experiences in direct surgical clipping of large and giant paraclinoid aneurysms, especially in dealing with anterior clinoidectomy, distal dural ring resection, optic canal unroofing, clipping techniques, and surgical complications. Methods : Between September 2001 and February 2012, we directly obliterated ten large and giant paraclinoid aneurysms. In all cases, tailored orbito-zygomatic craniotomies with extradural and/or intradural clinoidectomy were performed. The efficacy of surgical clipping was evaluated with postoperative digital subtraction angiography and computed tomographic angiography. Results : Of the ten cases reported, five each were of ruptured and unruptured aneurysms. Five aneurysms occurred in the carotid cave, two in the superior hypophyseal artery, two in the intracavernous, and one in the posterior wall. The mean diameter of the aneurysms sac was 18.8 mm in the greatest dimension. All large and giant paraclinoid aneurysms were obliterated with direct neck clipping without bypass. With the exception of the one intracavenous aneurysm, all large and giant paraclinoid aneurysms were occluded completely. Conclusion : The key features of successful surgical clipping of large and giant paraclinoid aneurysms include enhancing exposure of proximal neck of aneurysms, establishing proximal control, and completely obliterating aneurysms with minimal manipulation of the optic nerve. Our results suggest that internal carotid artery reconstruction using multiple fenestrated clips without bypass may potentially achieve complete occlusion of large paraclinoid aneurysms.

  • This article reviews the research products on user instruction of Korean university libraries. The focus is on identifying the trend, main features, and limitations of the relevant literature, with emphasis on both contents and methodology. To the end, 127 journal articles and theses are collected and analyzed, which have been produced since the mid-1970s. As a result, it is recognized the advanced research are not useful enough to be a knowledge base of Korean reference librarians, who have endeavored to improve the qualities of their user instruction programs. Above all, the advanced research turned out to be too much dependent on American theories and practices, instead of focusing on both indigenous phenomena and substantial problems which have been inherent in Korean university libraries.

  • Exposure to environmental factors can cause interstitial lung diseases (ILDs); however, such types of ILDs are rare. From 2007 to 2011, an ILD epidemic occurred in South Korea owing to inhalational exposure to toxic chemicals in humidifier disinfectants (HDs). HD-associated ILDs (HD-ILDs) are characterized by rapidly progressing respiratory failure with pulmonary fibrosis and a high mortality rate of 43.8%-58.0%. Although 18.1%-31.1% of the general population used HDs, only a small proportion of HD users were diagnosed with HD-ILDs. This finding suggests that investigation of the pathophysiologies underlying HD-ILDs is needed in addition to the identification of susceptibility to HD-ILDs. Further, there have been several concerns regarding the diverse health effects of exposure to toxic chemicals in HDs, including those that have not been identified, and long-term prognoses in terms of pulmonary function and residual pulmonary lesions observed on follow-up chest images. In this review, we summarize the clinical features, pathologic findings, and changes in radiologic findings over time in patients with HD-ILDs and the results of previous experimental research on the mechanisms underlying the effects of toxic chemicals in HDs. Studies are currently underway to identify the pathophysiologies of HD-ILDs and possible health effects of exposure to HDs along with the development of targeted therapeutic strategies. The experience of identification of HD-ILDs has encouraged stricter control of safe chemicals in everyday life.

  • This article intends to analyse some features in Exclusion Clauses of the Institute Cargo Clauses 2009 and the results of analysis are following. First, the insufficiency of packing or preparation exclusion under the revised Clause 4.3 is now more limited than before and the Clause suggest the test of sufficiency or suitability "to withstand the ordinary incidents of the insured transit". Secondly, the word "proximately" was deleted under the revised Clause 4.5 for the insurer to be identified more easily as a cause, but it remains to be seen whether that re-drafting will be successful. Thirdly, The exclusion under the revised Clause 4.6 does not apply unless the insurer can prove that, at the time the subject-matter insured is loaded on board the vessel, the assured was aware, or in the ordinary course of business should have been aware, that the relevant insolvency or financial default could prvent the normal prosecution of the voyage, and to a person who purchase the goods from the assured in good faith under a binding contract. Fourthly, the exclusion in respect of unseaworthiness of vessel under Clause 5.1.1 applies only where the assured is privy to the unseaworthiness, whereas the exclusion in respect of unfitness of container or conveyance under Clause 5.1.2 includes the privity of the employee. Finally, Clause 7 establishes the definition of terrorism, and adds ideological and religious motive to political motive.
