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: The treatment for chronic hepatitis C (CHC) is removal of the virus in order to prevent progression to liver cirrhosis and hepatocellular carcinoma (HCC). Few data have been presented regarding the clinical significance of changes in the alanine aminotransferase (ALT) level in this context. We analyzed the patterns of changes in ALT level and investigated the relationship between the rapid normalization of ALT and sustained virologic response (SVR) after combined treatment with peginterferon and ribavirin. METHODS: CHC patients (n=370) were classified into four groups according to the initial ALT level and subsequent changes: (1) initially abnormal ALT level and sustained abnormal ALT level during treatment, (2) initially abnormal ALT level but achievement of ALT normalization, (3) initially normal ALT level and variable ALT abnormality during treatment, and (4) initially normal ALT level and sustained normalization of ALT level during treatment. We subdivided groups 1 and 2 into those with patterns of decreased and normalization of ALT, with or without rapid normalization. We checked the end-treatment response (ETR) and SVR rates in each group and the factors associated with SVR, including patterns of changes in ALT level. RESULTS: A total of 168 patients completed the therapy (age=54.34+/-10.64 years [mean+/-SD], 95 males [56.5%], genotype 1:82 [48.8%]). SVR was achieved in 115 (68.45%) of the completely treated patients. The SVR rate was significantly lower in group 1 than in group 2 (37.8 vs. 81.6%, P<0.001), and significantly higher in the rapid normalization group than in the group without rapid normalization (78.5% vs. 41.2%, P<0.001). Multiple logistic regression analysis revealed that age (odds ratio [OR]=0.94, 95% confidence interval [CI]=0.91-0.98, P=0.005), viral genotype (OR=2.76, 95% CI=1.20-6.38, P=0.017), and initial hepatitis C virus RNA titer (OR=0.28, 95% CI=0.10-0.75, P=0.012) were identified as independent significant predictive factors for SVR. CONCLUSIONS: The SVR rate is significantly associated with normalization, and especially rapid normalization of ALT. Rapid normalization of ALT by 4 weeks after treatment might be a useful response factor that is readily available in clinical practice, and especially for genotype 1 patients.

Coxiella burnetii is the etiological agent of Q fever, that may occur either acutely or the chronically. To understand the seroepidemiological patterns of C. burnetii infection in Korea, we examined a total of 3,178 sera from patients with acute febrile episodes by using indirect immunofluorescence assay (IFA) for detectable antibodies to C. burnetii and other eight rickettsial antigens. The IFA seropositivity>or=1:20 for C. burnetii phase II was 11.5% (368 out of 3,178 sera). The co-existence of antibodies to other rickettsial antigens was found in 216 out of the 368 positive sera. Thirty-seven point five percent (n=138) had antibodies to R. tsutsugamushi (cutoff>or=1:20), 16% (n=59) to Ehrlichia sennetsu, 14.9% (n=55) to Rickettsia typhi, 13.5% (n=50) to R. akari, 11.4% (n=42) to R. japonica, 8.9% (n=33) to R. prowazekii, 7.6% (n=28) to R. sibirica, and 6.7% (n=25) to R. conorii by IFA, respectively. These results are consistent with previous reports documenting diverse serum cross-reactivity in chronic Q fever. Therefore we excluded the samples that reacted to other rickettsial antigens at same or higher titers than to C. burnetii, resulting in the seropositive rate of 4.1%. The serological prevalence was 2% (n=64) when the conventional cut-off titer of 1:80 was used. Our results suggest that infections with C. burnetii are more prevalent than expected previously and should be differentially diagnosised for febrile illness occurring after exposure to ticks or other vectors.

BACKGROUND/AIMS: Although transcatheter arterial chemoembolization (TACE) is a major treatment modality for unresectable hepatocellular carcinoma (HCC), acute hepatic failure after TACE is not rare. However, reports dealing with this important complication are not good enough and results are often variable. The purpose of this study was to evaluate the incidence and associated risk factors of acute hepatic failure after TACE. METHODS: From January 2001 to November 2004, six hundred and thirtytwo TACE sessions were performed in 377 patients (294 men and 83 women). Adriamycin mixed lipiodol solution and gelfoam were used for TACE. Various clinical and radiological factors before and after the procedure were reviewed retrospectively. Univariate and multivariate analyses were performed to evaluate the risk factors associated with the development of acute hepatic failure after TACE. RESULTS: Acute hepatic failure occurred in 76 (12.0%) of the 632 TACE sessions within 14 days. Univariate analysis revealed that Child-Pugh class, 1st TACE, total bilirubin level, number of involved segments, total size of tumor, presence of right portal vein thrombosis (PVT) or main PVT, involvement of segment 1, 5, 6, 7, modified UICC stage, and doses of chemotherapeutic agent were significantly different between the patients with or without hepatic failure after TACE. Among them, elevated total bilirubin (p=0.001, E (beta)=1.449), presence of right (p=0.035, E (beta)=2.109) or main (p=0.011, E (beta)=4.067) PVT were independently associated factors in multivariate analysis. CONCLUSIONS: The incidence of acute hepatic failure after TACE was 12.0%. Elevated bilirubin level and portal vein thrombosis could be considered as the predictive factors for acute hepatic failure after TACE in HCC patients.

Acute onset of shock presented in a 23 years old male patient due to gastrointestinal bleeding. He had been in a car crash 49 days before presentation. On initial presentation, a small amount of intraperitoneal hemorrhage had been seen on a CT scan. An emergency selective superior mesenteric artery (SMA) arteriography revealed a pseudoaneurysm in the branch of SMA, but successive embolization of the terminal branch controlled the bleeding. It is hard to initially diagnose an aneurysm as the cause of spontaneous gastrointestinal bleeding in a patient that has suffered an abdominal trauma, so it poses a therapeutic challenge. Recognition of an aneurysm, and its early diagnosis based on the patient's past history, and its adoption as a judicious diagnostic tool are essential in the management of such patients.
