BACKGROUND: Inflammatory bowel disease(IBD) such as ulcerative colitis or Croln's disease is often related with varied diseases including pyoderma gangrenosum, erythema nodosum, ankylosing arthritis and psoriasis. To date, however, a cIinical observation of IBD accompanied by psoriasis has been sparcely accomplished although an immunogenetic mechanism explaining a coexistence of IBD and psoriasis has been proposed. OBJECTIVE: We estimated the prevalence of IBD in patients with psoriasis in Korea and investigated the clinical characteristics of IBD accompanied by psoriasis. METHODS: 92 psoriatic patients and 389 non-psoriatic control subjects were enrolled in this study. Colonoscopic biopsy and barium series were performed in 47 psoriatic patients and 110 control subjects showing irritative intestinal symptoms. RESULTS: 1. The prevalence of IBD in psoriatic patients(14.1%) was significantly greater than in the control group(1.0%). 2. In the temporal relationship, psoriasis developed several years prior to the onset of IBD in 84.6% of psoriatic patients. 3. The frequency of arthropathies in the psoriatic patients possessing IBD(84.6%) was significantly higher than that of non-psariatic counterparts with IBD(25.0%) or that of psoriatics without lBD(2.5%), 4. The psoriatir. patients with IBD demonstrated much more frequently diffuse colonal extension than in non-psoriatic subjects with IBD. CONCLUSION: Our findings of an increased prevalence of IBD in the psoriatic population present further evidence of an association between IBD and psoriasis. In the psoriatic patients showing acute or chronic gastrointestinal symptoms, colonoseopic evaluation might be mandatory for the evaluation of IBD.

PURPOSE: Sleep disorder is common in childhood and adolescence with prevalence of 27-62%, and the patients could have trouble with their daily life due to fatigue and headache; and it can also cause developmental disability, learning disorder, anxiety disorder, and depressive disorder. We studied the prevalence of anxiety and depressive disorder in childhood and adolescence with sleep disorder. METHODS: We studied 34 cases of patients under twenty-year-old who took a sleep polysomnography test at Sleep Center of Keimyung University Dongsan Medical Center and who could answer sleep survey questionnaires; and we used testing methods of Questionnaire for insomnia, Epworth sleepness scale, Hospital Anxiety Depression Scale, and Back Depression Inventory. We studied sleep disorder as two categories of sleep apnea and other sleep disorders and also the relationships of sleep and anxiety and depressive disorder with chi-square test. RESULTS: 29.4% of sleep disorder patients had anxiety disorder, and 47.1% depressive disorder. Considering the two categories of sleep disorder, anxiety disorder was significantly higher(P<0.005) in sleep apnea group with 43.5% than in other sleep disorder group with 9.1%. Depressive disorder was also significantly higher(P<0.05) in sleep apnea group with 65.6% than in other sleep disorder group with 36.4%. CONCLUSION: The patients with sleep disorder also had a tendency of having mood disorder, with prevalence of 29.4% of anxiety disorder and 47.1% of depressive disorder; especially in the group of sleep apnea, mood disorders was significantly higher than other sleep disorder group, which means more aggressive diagnosis and treatment are needed for the combined condition of sleep and mood disorder.

The etiology of the postoperative discitis is not fully known, but most likely, the cause seems to be of a low grade infection and chemical and mechanical injuries. The incidence of these complication is from 0.12% to 2.6% of all cases. The characteristics of this disease are recurrence of severe lower back and gluteal pain, spasm of lumbar paravertebral muscle and elevated E.S.R. following the asymptomatic post-operative period, a roentgenogram showed an early destructive change in the adjacent vertebra, the narrowing of the intervertebral disc space, sclerotic changes in the vertebral bone and occasional fusion of the spine, and relatively good prognosis. We present a case of recurrent postoperative discitis with E.S.R. change and roentgenographic change.

Objective: To investigate the suitability of citrus-press cakes, by-products of the juice industry as a source for the whitening agents for cosmetic industry.
Methods:Ethylacetate extracts of citrus-press cakes (CCE) were examined for their anti-melanogenic potentials in terms of the inhibition of melanin production and mechanisim of melanogenesis by using Western Blot analysis with tyrosinese, tyrosinase-related protein-1 (TRP-1), TRP2, and microphthalmia-associated transcription factor (MITF) proteins. To apply the topical agents, citrus-press cakes was investigated the safety in human skin cell line. Finally flavonoid analysis of CCE was also determined by HPLC analysis.
Results: Results indicated that CCE were shown to down-regulate melanin content in a dose-dependent pattern. The CCE inhibited tyrosinase, TRP-2, and MITF expressions in a dose-dependent manner. To test the applicability of CCE to human skin, we used MTT assay to assess the cytotoxic effects of CCE on human keratinocyte HaCaT cells. The CCE exhibited low cytotoxicity at 50 μg/mL. Characterization of the citrus-press cakes for flavonoid contents using HPLC showed varied quantity of rutin, narirutin, and hesperidin.
Conclusions:Considering the anti-melanogenic activity and human safety, CCE is considered as a potential anti-melanogenic agent and may be effective for topical application for treating hyperpigmentation disorders.

Background:
The advance in microsurgical technique has facilitated a proper approach for reconstruction of extensive head and neck defects. For the success of free tissue reconstruction, selection of the recipient vessel is one of the most important factors. However, the vascular anatomy of this region is very complex, and a clear guideline about this subject is still lacking. In this study, we present our 30 years of experiences of free tissue reconstruction for head and neck defects.
Methods:
In this retrospective study, we analyzed a total of 138 flaps in 127 patients who underwent head and neck reconstruction using free tissue transfer following tumor resection between October 1986 to August 2019. Patients who underwent facial palsy reconstruction were excluded. Medical records including patient’s demographics, detailed operation notes, follow-up records, and photographs were collected and analyzed.
Results:
Among a total of 127 patients, 10 patients underwent a secondary operation due to cancer recurrence. The most commonly used type of flap was radial forearm flap (n= 107), followed by the anterolateral thigh flap (n= 18) and fibula flap (n= 10). With regard to recipient vessels, superior thyroid artery was most commonly used in arterial anastomosis (58.7%), and internal jugular vein (51.3%) was the first choice for venous anastomosis. The flap survival rate was 100%. Four cases of venous thrombosis were resolved with thrombectomy and re-anastomosis.
Conclusion
Superior thyroid artery and internal jugular vein were reliable choices as recipient vessels. Proper recipient vessel selection could improve the result of head and neck reconstruction.

BACKGROUND/AIMS: Endoscopic ultrasonography (EUS) has been used to discriminate gastric mucosal cancer (T1m) from submucosal invasion (T1sm). Thus the aims of this study are 1) to determine the accuracy of EUS for diagnosing tumor depth, 2) to compare the accuracy of EUS with the endoscopic impressions of variously experienced endoscopists and 3) to compare the accuracy of performing EUS by one doctor according to the experience. METHODS: The EUS and pathologic reports of early gastric cancer patients were analyzed. The same endoscopic images were reviewed again by 3 endoscopists, who had one-, three- and five-years experience, respectively. The accuracies of EUS and conventional endoscopy were analyzed. RESULTS: 77 patients were included from November 2003 to October 2005. The kappa of the EUS for actual examiner and conventional endoscopy for reviewer 1, reviewer 2 and reviewer 3 were 0.421, 0.134, 0.359 and 0.307, respectively and accuracies were 68.8%, 45.5%, 67.5% and 62.3%, respectively. Of the 52 T1m patients, 23 (44.2%) were overstaged as T1sm with performing EUS. But of 25 T1sm patients, only 1 (4.0%) was understaged as T1m with performing EUS. The accuracy and kappa of the EUS for one doctor during the first-year experience were 60.6% and 0.316, respectively, and they were 75.0% and 0.508, respectively during the second-year experience. CONCLUSIONS: EUS is useful for complementing the conventional endoscopic discrimination of gastric mucosal cancer from submucosal invasion. Yet physician should keep in mind the relatively common overstaging.

Ehrlichia sennetsu is the causative agent of human Sennetsu ehrlichiosis. Ehrlichiosis is an acute and occasionally chronic infectious disease caused by obligate intracellular bacteria in the family Rickettsiaceae. To understand the seroepidemiological patterns of ehrlichiosis in Korea, a total of 2,625 patients with acute febrile episode reported from 1990 to 1992 were surveyed using an indirect fluorescent antibody assay (IFA). The result was as follows. Seropositivity for ehrlichiosis was 3.23% by excluding highly cross-reacted sera with other rickettsial antigens. Sera reacted to E. sennetsu showed the cross reaction with other rickettsia as in the order of R. typhi 49.6%, R. conorii 31.6%, R. japonica 28.1%, C. burnetii 26.4%, R. sibirica 25.8%, O. tsutsugamushi 25.8%, R. akari 25.4%, and R. prowazekii 25.4%. Sexual difference in the seropositivity was not noted. The age groups of fifties and under the tenth showed higher prevalence than others. Seropositivity was most prevalent in July and August. As for regional distribution, Chonbuk (10.5%) showed the highest seropositive rate. Geographical distribution of the seropositivity covered most area except Cheju province in Korea.

Primary hepatic leiomyosarcoma is a very rare tumor of the liver and primary hepatic leiomyosarcoma with Behcet's disease has not been reported previously. Behcet's disease is a multisystem disorder presenting with recurrent oral and genital ulcerations as well as ocular lesions; it has rarely been reported in association with malignant disease. We report a case of primary hepatic leiomyosarcoma with intrahepatic and abdominal subcutaneous metastasis in a patient with Behcet's disease; this is the first report of these findings in Korea.

BACKGROUND/AIMS: In spite of increasing interests about nonalcoholic steatohepatitis (NASH), there are few reports about the ultrastructure of hepatocyte in this disease. The aim of this study was to clarify abnormal electron microscopic (EM) findings and related factors in NASH. METHODS: Total of fourteen patients who underwent liver biopsy due to steatohepatitis were included. Precise personal history was taken and variable blood tests such as liver function test, lipid profile, and serum iron study were done. Pathologic examination with light and electron microscopy was done by single pathologist. RESULTS: Eleven men and three women were included and mean age was 33.7+/-12.8 years. Nine patients drinking less than 40 g/week was grouped as "NASH group" and other 5 patients drinking more than 40 g/week and body mass index less than 25 was grouped as "ASH (Alcoholic Steatohepatitis) group". Polymorphism of mitochondria such as megamitochondria or loss of cristae was major abnormal EM findings and was more common in "NASH group" than "ASH group" (p=0.027). There was no significant clinical or pathological factors related with the presence of these abnormal EM findings. CONCLUSIONS: Polymorphism of mitochondria is major abnormal EM finding of steatohepatitis and is more common in NASH than ASH. And there is no significant clinical or pathological factors which could predict the presence of these abnormal EM findings.
