Hereditary nonpolyposis colorectal cancer(HNPCC) is an autosomal dominantly inherited disease associated with a marked increase in cancer susceptibility, especially cancer of the colorectum. The frequency of HNPCC in the general population is yet to be determined, but HNPCC may account for as much as 2% to 5% of colorectal cancer, Colorectal cancer in HNPCC differs from sporadic colorectal cancer by an early age of cancer onset, proximal predominance of colorectal cancer, an excess of synchronous and metachronous colorectal cancer, and excess extra-colonic cancers. We have found 5 HNPCC families since 1992 when we reported first HNPCC family (KHU-Hl) In order to register the patients of HNPCC and to review the clinicopathologic feature and appropriate management, we have analysed 5 HNPCC families. Five HNPCC families included 16 colorectal cancer patients(14 males and 2 females). The average age of first diagnosis was 39. Among 16 patients, 8 patient were operated at the KyungHee University hospital and their operative and pathologic records were available. Two synchronous and seven metachronous cancers were founded, so that eight patients had 15 colorectal cancer lesions. Ten cancers were located proximal to splenic flexure and five were distal. Partial resection of colon was performed in seven cases except one when the first diagnosis was made and recurrence was founded in 5 patients. Recurrence was treated by total colectomy in 3 cases and subtotal colectomy in two. In conclusion, we re-confirmed that HNPCC patient should be treated by no less than a subtotal colectomy because of high multiplicity and high recurrence rate of partial resection.

PURPOSE: The purpose of this study was to determine the role of CT and MR imagings in the diagnosis aortic dissection and differentiation between the true and false lumen. MATERIALS AND METHODS: We retrospectively studied forty patients with aortic dissection(AD) diagnosed imagings or surgery. Of the forty patients, 19 were examined with only CT, 14 with CT and MR, and 7 with MI~: Our points of view were(1) the classification of AD according to configuration of intimal flap by cross-sectional imaging, (2) differentiation between the true and false lumens, (3) the course of the false lumen, and (4)! detectability of the origin of major branch vessels of the abdominal aorta. RESULTS: The classification by corss-sectional imaging were crescentic(65%), circumferential(15%), flat(12%), and irregular(8%) type, in which false negative diagnosis was made in 1 case of crescentic and circumferential type, respectively. In 2 case of flat type and 1 case of irregular type, the differentiation between the true and false lumen was impossible with CT. The course of the false lumen in descending thoracic aorta revealed countrclock wise rotation(66%), clockwise rotation(5%) or fixed(29%) apperance. MR imaging was superior to CT in the detection of the origin of major branch vessels of the abdominal aorta. The determination of the origin of major branches of abdominal aorta arising from the true and false lumen were impossible in 2 cases in which only CT was done. CONCLUSION: Diagnosis of crescentic and circumferential types of AD with narrow and thrombosed false lumen was problematic in both CT and MR with no difference of diagnostic accuracy between the two modalities. The differentiation between the true and false lumen was difficult in flat and irregular types with only CT. Therefore, when surgical treatment is considered as in type B aortic dissection, MR imaging is recommended in order to determine the origin of major branch vessels.

7.Association between Skin Phenotype and Apocrine Bromhidrosis in Koreans.
Korean Journal of Dermatology 2002;40(5):496-500
BACKGROUND: The diagnosis of bromhidrosis is a clinical one, but the definition of "normal" odor is a poorly defined term. In the Asian population, the presence of even a faint odor is considered diagnostic. For the more exact evaluation, it is vital to study more findings associated with bromhidrosis. Recently, several studies have suggested possibility that the activity of sebaceous gland may be increased in patients with bromhidrosis. OBJECTIVE: The aim of this study was to compare the differences of the seborrheic phenotypes and the measured serum level of facial skin surface between patients with bromhidrosis and the normal population. METHODS: Twenty patients who were diagnosed with bromhidrosis by nose smell test and age-matched twenty from the normal population were evaluated with regard to the presence of seborrheic skin phenotypes suggested by Ely. We also measured sebum level of facial skin by Sebumeter(R). RESULTS: The presence of some seborrheic skin phenotypes such as telangiectasia and square palm were increased significantly in the patients. In addition, objectively measured sebum of facial skin surface was relatively increased in the patients. CONCLUSION: We concluded that there is an association between apocrine bromhidrosis and seborrheic skin phenotype.

Various surgical methods have been used to reconstruct severe soft tissue defects of the finger with exposed critical structures such as tendon, bone, and nerve. Some of these methods include rotation flap, cross finger flap, or regional flap similar to neurovascular island flap. However, there were often difficult situations where a flap could not be applied depending on the remaining surrounding tissue, injured area, and size of defect. As a result, free flap or distant flap may become necessary. However, distant flaps often cause stiffness of the finger joints since the hands need to be immobilized for a long time, while standard free flaps may be too thick to cover the finger and cause problems such as morbidities of the donor site. Since May, 1997, at Anam Hospital, we have performed reconstruction on 6 patients with soft tissue defect using a thin, flexible medial plantar septo-cutaneous free flap similar to the volar aspect of the finger in anatomical characteristics of the skin and subcutaneous tissue covering. The vessels used for this flap were superficial branches of medial division of the medial plantar artery and vena comitantes, or the subcutaneous veins. The mean size of the flaps was 2.75cm x 4.25cm. Primary repair or split-thickness skin graft was performed on the donor site depending on the size. All the flaps survived without significant complications, except one case of venous insufficiency. The composition of the transferred flaps was good with the recovery of pain, touch and temperature sensation. A free medial plantar septo-cutaneous flap has several advantages, e.g., it is small in comparison with other standard free flaps, having two draining venous pathways, good color and texture, and a good recovery of protective sensation. This flap can be used for the reconstruction of soft tissue defect on the heel and foot, as well as the volar aspect of fingers.

To assess the clinico-pathological characteristics of patients with multiple primary colorectal cancer, 458 patients who underwent curative surgery and being followed-up at our institution between Jan. 1987 and Dec. 1993 were evaluated in this study. The median follow-up period was 42 months. Synchronous cancer was defined as distinct lesions separated by a distance of greater than 4cm with the invasion of the tumor below the muscularis mucosa at the time of diagnosis or within 6 months after initial treatment, and metachronous cancer was defined as the development of colon cancers more than 6 months after the initial treatment without evidence of the recurrence or metastases from primary tumor. There were 29 cases of multiple primary colorectal cancer(6.3%). Eighteen cases(3.9%) of them were synchronous, 11 cases(2.4%) were metachronous cancers. Seven cases(1.5%) were related to 5 hereditary non-polyposis colorectal cancer(HNPCC) families. During the follow-up period, 11 patients(2.4%) developed cancers in other organs. Adenomatous polyps were identified 14 cases of 29 patients with multiple primary colorectal cancers(48.3%), compared to 43 cases(10%) in 429 patients with solitary colorectal cancer(p<0.01). After initial curative surgery, there were 8 recurrences in 29 patients with multiple primary colorectal cancers(23.6%), compared to 100 recurrences in 429 patients with solitary primary colorectal cancer(23.3%)(p>0.05). In aspect of family history, there was close-relationship with this regarding in the group of multiple primary colorectal cancers. However, authors were unable to make analysis this regarding in the group of solitary primaries because of lack of the information. Conclusively, authors guess the frequent association of the adenomatous polyps in multiple primary colorectal cancers as the evidence of the adenoma-carcinoma sequence. In addition, authors emphasized the importance of the total colonoscopic examinations in pre-and post-operation in order to make diagnosis of the multiple primary colorectal cancers and paying attention as to the family history of colorectal cancer patients because we have good therapeutic results after operation of early stage in synchronous cancers and co-existent adenomatous polyps.

In recognition of Korea's rising burden of non-communicable diseases (NCDs), we investigated the nation's NCD status and extracted detailed information from the 2012 Korean Burden of Disease study. Consistent with that study, we used disability-adjusted life year (DALY) as a metric. Using national data sources and disability weights specific to the Korean population, we analyzed 116 disaggregated NCDs from the study's four-level disease and injury hierarchy for both sexes and nine age groups. Per 100,000 population, 21,019 DALYs were lost to 116 NCDs. Of those, 13.97% were due to premature death (death prior to the standard life expectancy for a subject's age) and 86.03% to non-fatal health outcomes. Based on traditional statistics, the main causes of health loss were mortality of neoplasms; cardiovascular and circulatory diseases; diabetes, urogenital, blood, and endocrine diseases; and chronic respiratory diseases. When combined with analyses of premature death and non-fatal outcomes, however, a substantially different view emerged: the main causes of health loss were diabetes mellitus, low back pain, chronic obstructive pulmonary disease, ischemic heart disease, ischemic stroke, cirrhosis of the liver, osteoarthritis, asthma, gastritis and duodenitis, and periodontal disease (in that order), collectively causing 49.20% of DALYs. Thus, burden of disease data using DALYs rather than traditional statistics brings a new perspective to characterization of the population's health that provides practical information useful for developing and targeting national NCD control programs to better meet national needs.
