A burnt-out prostate cancer tumor is a very rare clinical entity. The term 'burnt-out' refers to a primary tumor that has spontaneously and nearly completely regressed without treatment. Since metastasis of prostate cancer is usually encountered in the presence of advanced disease, distant metastasis with an undetectable primary tumor is very rare. We report herein a case of a burnt-out prostate cancer tumor that metastasized to the thoracic (T) spine and caused cord compression. A 66-year-old man visited the Emergency Department due to weakness of both legs for the past two days. His blood and urine tests were normal at the time. His spine magnetic resonance imaging (MRI) scans looked like bone metastasis that involved the T-7 vertebral body and a posterior element, and caused spinal cord compression. Other images, including from the brain MRI, neck/chest/abdomino-pelvic computed tomography (CT) scan and 18F-fluorodeoxyglucose (FDG)-positron emission tomography (PET) and endoscopy, revealed no lesions that suggested malignancy. After total corpectomy T-7 and screw fixation/fusion at T5 to T10, the pathology report revealed a metastatic carcinoma that was strongly positive for prostate-specific antigen (PSA). The serum PSA value was 1.5 ng/mL. The transrectal 12-core prostate biopsy and ultrasonography showed no definitive hypoechoic lesion, but one specimen had slight (only 1%) adenocarcinoma with a Gleason score of 6 (3+3). The final diagnosis was burned-out prostate cancer with an initial normal PSA value. Although metastatic disease with an unknown primary origin was confirmed, a more aggressive approach in seeking the primary origin could provide a more specific treatment strategy and greater clinical benefit to patients.

Background: Topical corticosteroids (TCs) are available both as over-the-counter drugs and prescription medicines at pharmacies.Although they are generally safe drugs, inappropriate and excessive use could result in potential side effects. Thus, it is important to have appropriate knowledge regarding the use of TCs. We performed a cross-sectional survey to assess public knowledge and the potential misuse or overuse of TCs. Methods: A cross-sectional and nationwide online survey was conducted among participants who were aware of TCs. The survey items included sources of information, indications, potential side effects, and methods of application of TCs. A comparative analysis was conducted between those with (TC users) and without (TC non-users) an experience of using TCs. Results: Among 3,000 participants, 74.4% were TC users. The mass media was the most common information source of TCs, and only one-third of the surveyed people relied on pharmacists or doctors for information. Regarding indications and application methods, incorrect answer rate was high in some items, but respondents showed adequate knowledge. However, awareness of the safety of TCs was low. Overall, the TC users showed a higher knowledge of TCs than TC non-users. Conclusions Public knowledge of the use of TCs appears to be appropriate. However, we found potential misuse or overuse of some items and a lack of awareness of the side effects concerning TCs. Thus, healthcare professionals’ significant role is required.

Sedation is often necessary to optimize care for critically ill children requiring mechanical ventilation. If too light or too deep, however, sedation can cause significant adverse reactions, making it important to assess the degree of sedation and maintain its optimal level. We evaluated the efficacy of the COMFORT scale in assessing optimal sedation in critically ill children requiring mechanical ventilation. We compared 12 month data in 21 patients (intervention group), for whom we used the pediatric intensive care unit (PICU) sedation protocol of Asan Medical Center (Seoul, Korea) and the COMFORT scale to maintain optimal sedation, with the data in 20 patients (control group) assessed before using the sedation protocol and the COMPORT scale. Compared with the control group, the intervention group showed significant decreases in the total usage of sedatives and analgesics, the duration of mechanical ventilation (11.0 days vs. 12.5 days) and PICU stay (15.0 days vs. 19.5 days), and the development of withdrawal symptoms (1 case vs. 7 cases). The total duration of sedation (8.0 days vs. 11.5 days) also tended to decrease. These findings suggest that application of protocol-based sedation with the COMPORT scale may benefit children requiring mechanical ventilation.

To evaluate the effect of anabolic steroid(AS) on body composition and protein metabolism in malnourished CAPD patients, 7 CAPD patients who were proved to be malnourished by subjective global assessment received 200mg of AS, nandrolone decanoate, by intramuscular route monthly for 5 months. We analyzed the body composition, biochemical nutritional markers, plasma and dialysate amino acids(AA) before and after administration of AS. The mean age was 53.6+/-11.5 years, the sex ratio was 2:5, and the duration of CAPD was 28.5+/-18.7 months. Two patients were diabetics. Five months after AS administration, %lean body mass seemed to increase from 52.6+/-11.7 to 57.3+/-11.0%(P>0.05), but there were no significant changes in body weight and body mass index. Serum insulin-like growth factor-I (172.4+/-88.5 vs. 204.1+/-85.8ng/ml, P<0.05) and transferrin(213.6+/-55.4 vs. 239.0+/-55.3mg/dl, P<0.05) were significantly increased, and serum total CO2(31.1+/-4.5 vs. 25.9+/-2.5mM/L, P<0.05) were significantly decreased. Urea nitrogen appearance(4.0+/-2.0 vs. 3.6+/-1.6g/ day) seemed to be decreased. Both plasma essential AA(EAA) level(738.3+/-206.5 vs. 492.5+/-187.2micromol/L, P<0.05) and peritoneal EAA loss(565.0+/-186.1 vs. 377.4+/-113.9micromol/day, P<0.05) decreased significantly after administration. Plasma total and non- essential amino acids(NEAA) level tended to be increased and peritoneal total and NEAA loss seemed to be decreased without statistical significance. In conclusion, AS seems to have anabolic effect and be useful in the correction of malnutrition in CAPD patients.

Behcet's disease is a chronie inflammatory symptom complex consisting of recurrent oral ulcer, genital ulcer, ocular lesion or skin lesion. Intestinal involvement in Behcet's disease most commonly affects the ileocecal region in the patient with gestrointestinal symptoms, But esophageal involvement in Behcet's disease is very uncommon, most commonly affects the midesophagus with localized ulcerative lesion. A 38-Year-old woman with refractory and recurrent oral and genital ulcer was admitted because of aggravation of pharyngodynia and dysphagia. Gastrofiberscopic examination showed multiple, small sized ulcers on oral cavity and mid-to-distal esophagus. She was treated with steroid.

BACKGROUD: To study the prevalence of abnormalities found in routine preoperative eletrocardiograms (ECGs) and to analyze abnormal ECG findings in different age groups. METHODS: 9,709 patients undergoing elective surgery requiring anesthesia at Busan Paik Hospital from January to December 2002 were retrospectively studied. Preoperative ECGs were analyzed in terms of age, sex and specific abnormal ECG findings that might alter anesthetic management. RESULTS: 1,683 of 9,709 patients (17.3%) had abnormal electrocardiogram findings. The incidences of ventricular hypertrophy, bundle branch block, myocardial ischemia, arrhythmia, myocardial infarction and atrioventricular block were 5.3%, 4.1%, 3.9%, 2.5%, 1.0% and 0.5%. Those over 75 years, 43% had abnormal findings and the incidence of myocardial ischemia, arrhythmia and ventricular hypertrophy were 11.7%, 9.7% and 8.7%. CONCLUSIONS: The prevalence of unexpected preoperative ECG abnormalities among elective surgery patients is high, especially among older patients. Given the wealth of information provided by preoperative ECG at low cost, ECG is necessary to establish the components of routine preoperative assessment for cardiovascular disease, especially for older adults.

Benign recurrent intrahepatic cholestasis (BRIC) is a rare desease, which usually manifests between the age of 10 and 20. Its main clinical feature is multiple recurrent episodes of cholestasis without extrahepatic bile duct obstruction. We report here a case of nonfamilial benign recurrent intrahepatic cholestasis. The patient has experienced recurrent jaundice with pruritus since childhood. Main bile duct obstrution was excluded by abdominal CT and endoscopic retrograde cholangiopancreatography. Other causes of cholestasis were not found. Hepatic histology revealed bile plug which were mainly concentrated in the centrilobular region, and increased number of mononuclear cells in the portal triad, but hepatic parenchyma showed no inflammation and necrosis. In the last anicteric period, she was healthy and the liver function test and biopsy specimen were normal.

OBJECTIVE: To evaluate the differences of mid-trimester triple marker levels in patients with mild versus severe and early versus late onset preeclampsia. METHODS: From January 2000 to December 2004, a retrospective study of 65 women with preeclampsia for whom mid-trimester triple test data were available was made. None of these patients had diabetes, other medical disorders, multiple pregnancy, abnormal karyotype and malformations. Preeclampsia patients were grouped to "early onset" [<32 weeks of gestation (wks), n=17] and "late onset" (n=48), and also "mild" (who had delivered with no symptoms and lab findings of severe preeclampsia at term spontaneous labor or elective cesarean delivery, n=31) and "severe" (n=34). The levels of mid-trimester maternal serum alpha-fetoprotein (MSAFP), human chorionic gonadotropin (hCG) and unconjugate estriol (MSuE3) in patients with early and late onset, mild and severe were compared. RESULTS: The each groups of comparison did not differ significantly with regard to age, weight, parity. The mean MSuE3 [0.92+/-0.09 (MoM+/-SE)] in patients with early onset was significantly lower than in patients with late onset preeclampsia (1.24 MoM, SE 0.07). In the comparison according to severity, the mean MSuE3 was significantly lower (0.98 MoM, SE 0.06 vs 1.28 MoM, SE 0.10, p=0.016) and the mean hCG was significantly higher (1.46 MoM, SE 0.12 vs 1.12 MoM, SE 0.07, p=0.015) in patients with severe preeclampsia than in those had mild preeclampsia symptoms at term delivery. CONCLUSION: Lower levels of mid-trimester MSuE3 and higher levels of hCG were associated with the severe preeclampsia rather than mild. Especially, lower levels of mid-trimester MSuE3 was also associated with early onset preeclampsia.
