Crohn's disease can cause intestinal strictures, perforations, fistulas, or abscesses. Although fistulas and abscesses are common complications of Crohn's disease, a presacral abscess with neuromuscular complications is very unusual. A delayed diagnosis and treatment may increase morbidity. The diagnosis is frequently delayed, because the clinical features of presacral abscess are variable and nonspecific. We experienced a case of a presacral abscess with bilateral sciatica in a 25-year-old male patient. He was diagnosed with Crohn's disease of the terminal ileum 2 months previously and has been managed with mesalazine. He visited our hospital due to pain in the buttocks and severe neuralgia in both thighs. We confirmed enteric fistulas, resulting in a presacral abscess, which extended symmetrically through both sciatic notches and the gluteus medius muscles. He was managed with antibiotics after a small bowel segmentectomy, right hemicolectomy, fistulectomy, and surgical drainage. The bilateral radicular pain resolved completely within 2 weeks of surgery. The patient has remained in remission and asymptomatic 1 year after surgery.

BACKGROUND: Osteomyelitis is an intraosseous inflammatory disease characterized by progressive inflammatory osteoclasia and ossification. The use of quantitative analysis to assist interpretation of osteomyelitis is increasingly being considered. The objective of this study was to perform early diagnosis of osteomyelitis on digital panoramic radiographs using basic functions provided by picture archiving and communication system (PACS), a program used to show radiographic images. METHODS: This study targeted a total of 95 patients whose symptoms were confirmed as osteomyelitis under clinical, radiologic, pathological diagnosis over 11 years from 2008 to 2017. Five categorized patients were osteoradionecrosis, bisphosphonate-related osteonecrosis of jaw (BRONJ, suppurative and sclerosing type), and bacterial osteomyelitis (suppurative and sclerosing type), and the control group was 117 randomly sampled. The photographic density in a certain area of the digital panoramic radiograph was determined and compared using the “measure area rectangle,” one of the basic PACS functions in INFINITT PACS® (INFINITT Healthcare, Seoul, South Korea). A conditional inference tree, one type of decision making tree, was generated with the program R for statistical analysis with SPSS®. RESULTS: In the conditional inference tree generated from the obtained data, cases where the difference in average value exceeded 54.49 and the difference in minimum value was less than 54.49 and greater than 12.81 and the difference in minimum value exceeded 39 were considered suspicious of osteomyelitis. From these results, the disease could be correctly classified with a probability of 88.1%. There was no difference in photographic density value of BRONJ and bacterial osteomyelitis; therefore, it was not possible to classify BRONJ and bacterial osteomyelitis by quantitative analysis of panoramic radiographs based on existing research. CONCLUSIONS: This study demonstrates that it is feasible to measure photographic density using a basic function in PACS and apply the data to assist in the diagnosis of osteomyelitis.

BACKGROUND: The present study aimed to examine the association between cigarette smoking, alcohol consumption and colorectal cancer risk among Korean adults. METHODS: Data from the Korean Multi-center Cancer Cohort between 1993 and 2005 were analyzed. The study population comprised 18,707 subjects aged older than 20 years old. The subjects were followed until December 31, 2011 (median follow-up of 11.2 years). The Cox proportional hazard model was used to estimate the hazard ratio (HR) and 95% confidence intervals of cigarette smoking and alcohol consumption for colorectal cancer risk. RESULTS: In men, longer duration and higher average amount of alcohol consumption were associated with elevated risk of colorectal cancer (HR 1.93 [1.17-3.18] for > or = 30 years of consumption compared to non-drinkers; HR 2.24 [1.31-3.84] for > or = 30 g/d). Former smokers showed a non-significantly elevated risk of colorectal cancer in men. There was no apparent association between alcohol consumption or cigarette smoking and colorectal cancer risk among women. CONCLUSIONS: Alcohol consumption was associated with increased colorectal cancer risk among Korean men, and both a longer duration and a higher amount of consumption were associated with elevated risk.

Human brucellosis has a broad spectrum of clinical manifestations, which includes endocarditis, a focal complication that is uncommon yet responsible for the majority of associated deaths. The most successful treatment outcomes of Brucella endocarditis have been reported with usage of both antimicrobial agents and surgery. However, there are few reports on the treatment of Brucella endocarditis using antibiotics only. We report the first case in Korea of Brucella endocarditis with aortic valve vegetations and an accompanying splenic abscess, which were treated successfully with antibiotic therapy alone.

OBJECTIVES: To construct basic data to develop strategies for achieving higher Pap test coverage rate by evaluating factors associated with the use of Pap test through population-based survey. METHODS: 16.4%(671) of the 4,090 women, who were eligible population for this study, in 3 Myens of Chung-ju City participated in this study voluntarily from July 21 to 26, 1997. After basic physical examination by trained doctors, they were interviewed with structured questionnaire by well-educated interviewers. RESULTS: It shows that only 54.3% of study participants experienced Pap test. The strongest factor which is related with the use of Pap test was the history of having breast screening tests(aOR=8.71, 95% CI=4.25-17.84). Probability of ever having Pap test was also higher in married women(aOR of single=0.46, 95% CI=0.29-0.72), younger(Ptrend<0.05), more educated (Ptrend<0.001), non-smoker (aOR of smoker=0.26, 95% CI=0.12-0.55), women of ever having hepatitis test(aOR=2.60, 95% CI=1.73-3.88) in multiple linear logistic analysis. CONCLUSIONS: This study suggests that several factors significantly associated with the use of Pap test, and especially, high-risk population for cervical cancer such as women of older ages, less educated, living alone are less likely to have the Pap test. We should concentrate on encouraging high-risk women in the use of Pap test to improve Pap test coverage rate.

To evaluate the functional and radiologic outcomes of extracorporeal shock wave therapy (ESWT) in shoulders with chronic calcific tendinitis. We report a retrospective study to compare the outcome after ESWT (group l, 15 cases) with the effect of medication treatment (group 2, 15 cases) in patients with chronic calcific tendinitis. Patients were aged 42 to 58 years, mean of 48 years and treated with extracorporeal shock waves or medication from September 2012 to May 2014. The ESWT was performed six cycles of shock waves, weekly treatment for the three cycles and the rest cycles after 2 weeks of pause. In the same period, there were 12 women and 3 men treated with medication treatment for calcific tendinitis. The clinical outcomes were evaluated according to Constant and Murley score and pain visual analogue scale. Radiologic evaluation was performed to confirm disintegration of calcific deposits 3 months and 6 months after treatment. Clinical outcomes were significantly improved in ESWT group, and there was significant difference between ESWT group and medication group. In radiographic evaluation, the calcific deposit was significantly decreased in ESWT group. ESWT therapy is more effective to achieve functional improvement and to alleviate pain in the patients with calcific tendinitis of the shoulder.

OBJECTIVES: The aim of this study was to evaluate the roles of cigarette smoking, alcohol consumption, tuberculosis, and their interactions in the risk of lung cancer in a Korean cohort. METHODS: The study subjects comprised 13,150 males and females aged above 20 years old. During the follow up period from 1993 to 2002, 79 lung cancer cases were identified by the central cancer registry and the national death certificate database. Information on cigarette smoking, alcohol consumption and the history of physiciandiagnosed tuberculosis was obtained by interview. Indirect chest X-ray findings were also evaluated to ascertain tuberculosis cases. Cox proportional hazard models were used to estimate relative risks (RR) and 95% confidence intervals (CI) after adjusting for age and gender. RESULTS: Cigarette smoking was statistically significantly associated with an increased risk of lung cancer [for current smokers, RR = 2.33 (95% CI = 1.23 - 4.42) compared to non-smokers]. After further adjustment for cigarette smoking, both alcohol consumption and tuberculosis showed no statistically significant association with the risk of lung cancer [for current drinkers, RR = 0.80 (95% CI = 0.48 - 1.33) compared to non-drinkers] [for tuberculosis cases, RR = 1.17 (95% CI = 0.58 - 2.36) compared to noncases]. There was no statistically significant interaction between cigarette smoking and alcohol consumption (pinteraction = 0.38), or cigarette smoking and tuberculosis (p-interaction = 0.74). CONCLUSIONS: Although cigarette smoking was confirmed as a risk factor of lung cancer in this cohort study, this study suggests that alcohol consumption and tuberculosis may not be associated with the risk of lung cancer.

PURPOSE: To evaluate the usefulness of epinephrine infusion (Pharmaco-CTHA) prior to liver to liver spiral CT during hepatic arteriography in patients with hepatocellular carcinoma. MATERIALS AND METHODS: Twenty-two patients in whom hepatocellular carcinoma had been diagnosed underwent three types of liver spiral CT during hepatic arteriography. In the first method, spiral CT scanning was started 5 seconds after injecting 8cc of contrast media at a rate of 0.3cc/sec. In the second, 10 microgram of epinephrine was slowly injected for 1 minute via the catheter and subsequent spiral CT scanning began 11 seconds after injecting 8cc of contrast media at a rate of 0.3cc/sec. In the third method, spiral CT scanning was started 5 seconds after injecting 25cc of contrast media at a rate of 1cc/sec. The following were evaluated and compared with the results of follow-up lipiodol CT: 1) the incidence of false positive lesions; 2) the incidence of false negative lesions; 3) portal enhancement; and 4) lesion conspicuity. RESULTS: Follow-up lipiodol CT of 22 patients showed 16 masses. In 12 patients there was no lipiodol uptake, and in five, four and one patient(s), uptake occurred once, twice, and three times, respectively. With method 1there were nine false-positive lesions, with method 2 there were 13, and with method 3, there were 49. The use of method 2(Pharmaco-CTNA) led to less false-positives than did method 3 (conventional CTHA)(p=0.000). Method 1 showed the lowest false positive rate (nine lesions), but its false-negative rate was two and four times higher than with method 2 (four lesions) and with method 3 (two lesions), respectively. Portal enhancement was observed four times using method 3 and once with method 1, but was absent with method 2. As regards the conspicuity of 16 masses, "good" and "excellent" lesions were seen four times with method 1(25%), ten times with method 2 (62.5%) and thirteen times with method 3 (81.3%). CONCLUSION: The infusion of epinephrine (Pharmaco-CTHA) prior to spiral CT during hepatic arteriography has the advantage of reducing the amount of contrast media required as well as the number of cases which are false positive and show no portal enhancement.

The purpose of this study is to present the information on the duration of treatment and the cost of work-related low back pain. Using the compensation-database for 1997 work-related low back pain (n=9,277), this study estimated the duration of treatment, the cost of work-related low back pain, the relationship between them, and probability of being off treatment at different intervals. The mean and the median of the treatment duration are 252.6 days and 175 days. The mean and the median of the cost of total insurance benefit are 37,700,000 won and 14,400,000 won. The treatment duration of 51% of the study subjects was less than 6 months and their cost accounted for 10.2% of the total insurance benefit. The subjects who were treated more than 24 months were 5.8% but it accounted for 29.2% of the cost. It was found that approximately 50% of the subjects who will remain on treatment at the end of n months would be off treatment at the end of n+5 months. This study presents the point in time when the low back pain (LBP) workers need to prepare to return to work by forecasting their off-treatment period. From the treat duration and cost perspectives, this study may be utilized as evidence for active management of work-related LBP.
