ABSTRACT
BACKGROUND: Recently, many Korean people travel abroad where malaria is prevalent. However, in Korea, relatively little is known about compliance of chemoprophylaxis against malaria. This study was performed to determine the factors influencing compliance of chemoprophylaxis against malaria in Korean travelers. MATERIALS AND METHODS: Face to face interview, telephone interview and e-mail correspondence were performed to 241 people who were prescribed with atovaquone-proguanil at the international travelers' clinic of National Medical Center between February 2007 and October 2007. RESULTS: Total of 55 people out of 235 reported one or more events of adverse reactions after chemoprophylaxis (total 76 events). However, in 38 adverse events the link between chemoprophylaxis and adverse events were very weak. Compliance of malaria chemoprophylaxis with atovaquone-proguanil was 53.9% in the study group. The predictive factors for non-compliance were package tour, travel of business affair and young age group. Conclusions: Compliance of malaria chemoprophylaxis in Korea travelers was low compared with Dutch and French studies. More efforts to increase compliance are needed, especially in travelers on package tour, business travel and people under age 40.

BACKGROUND: Observation on the hemodialysis treatment; whether there are any different effects on mortality rate, side effects, or effectiveness of the treatment depending on patients' age. METHODS: Chronic renal failure patients who started hemodialysis treatment between 2002 and 2003 were separated in two groups, 33 patients of 60 and older and 76 patients under 60. We investigated mortality rate difference, A-V shunt re-operation, and total protein and albumin level. Also, comparing and analyzing the urea reduction ratio, we examined whether effectiveness is different depending on the patients' age. RESULTS: The 3 year survivor rate of patients who initially started hemodialysis treatment over 60 was 66.7%, and that of the patients under 60 resulted as 73.1%. The average total protein lefel for over 60 was 6.48g/dL and for under 60 was 6.80g/dL, and albumin for over 60 was 3.15g/dL and under 60 was 3.46g/dL. We identified that the patients who repeated shunt operation in over 60 group was 4(12%) and in under 60 group was 4(5.2%). Effectiveness of the treatment, Urea Reduction Ratio(URR), for both groups was 71%. CONCLUSION: The 3 year survivor rate of patients who initially started hemodialysis treatment over 60 was lower than the control group, but considering the remaining life expectancy, it seems to be no significant difference between the groups; and the treatment effectiveness was same in both groups.

BACKGROUND: Despite the expected high prevalence of several infectious diseases among the homeless, a majority of them have not received screening test and early treatment. MATERIALS AND METHODS: The subjects of this study were 269 homeless patients who had been hospitalized in the National Medical Center (Korea) between January 2002 and August 2004. Their medical histories and records were reviewed to analyze the prevalence and clinical characteristics of hepatitis B and C, syphilis, tuberculosis and HIV infection among them. RESULTS: The entire 269 homeless patients being hospitalized during the period of this study consist of 249 male patients and 19 female patients. For the prevalence of infectious diseases, HBV was seen in 15 of 228 patients (6.6%); HCV in 8 of 113 patients (7.1%); VDRL positive in 25 of 234 patients (10.7 %); HIV antibody positive in 2 of 130 (1.5%); and tuberculosis in 19 of 269 (7.1%). The number of patients who had the antibody to hepatitis B was 118 (51.7%). Of 28 patients hospitalized with the chief complaints of liver diseases and/or their complications, the number of cases infected with hepatitis B and C viruses was only 5 (17.9%). On the other hand, for patients with tuberculosis, 13 of 19 cases (68.4%) were hospitalized with the chief complaints associated with symptoms of pulmonary tuberculosis or enlarged lymph nodes. The number of patients with multiple infectious diseases was 9 in total. CONCLUSION: As expected, the prevalence of some infectious diseases were higher among the homeless inpatients, than non-homeless population. Proper screening tests in order to determine the presence of any infectious diseases among the patients and protect involved medical staff are necessary. Further, the government should take proactive measures to prevent the spread of infectious diseases in the aspect of public health.

Systemic manifestation of tuberculosis is common, but tuberculous biliary obstruction of the pancreas and a colon adenocarcinoma with combined colonic tuberculosis is an uncommon disorder. We encountered a case of the above condition in 63-year-old male that was admitted to our hospital because of fever, diffuse abdominal pain and rigidity. Abdominal computed tomography showed biliary and pancreatic duct dilatation with left colonic wall thickening and surrounding peritoneal infiltration. Emergency segmental resection of the descending colon with intraoperative T-tube choledochostomy was performed due to the colon mass and biliary obstruction. A colonofiberoscopy was performed for low abdominal pain and hematochezia at 12 days after surgery. It showed multiple colonic ulcerations with a partial stricture. A colonic biopsy showed granulomatous inflammation with acid-fast bacilli. The cause of the biliary obstruction was also revealed as pancreatic tuberculosis by an intraoperative pancreatic and mesenteric biopsy. The patient improved after antituberculous treatment and the patient has been in good health until the last outpatient follow-up visit.
