Isolated ACTH deficiency is a rare cause of secondary adrenocortical insufficiency caused by the defect of synthesis or release of ACTH in pituitary gland. The clinical presentation can be simiilar to that of primary adrenal insufficiency, but there is a greater tendency for hypoglycemia and absence of hyperpigmentation. The patient, 80 year-old female, was admitted in chief complaint of deteriorated mental states. On admission, serum sodium was 127mEq/L, potassium 4.4mEq/L, blood glucose 27mg/dL and on routine E.C.G. was atrial fibrillation was revealed. The basal morning serum cortisol level was 9.97 pg/dL it dosent respond to insulin-induced hypoglycemia enoughly, but other pituitary functions were intact in pituitary cocktail stimulation test. In CRH stimulation test, there was no remarkable response in serum ACTH and cortisol level. Brain MRI failed to reveal any anatomic abnormalities of the sellar or suprasellar area consistent with the defect of pituitary ACTH secretion. This case was a isolated ACTH deficiency, So, we conclude that associated with atrail fibrillation and hypoglycemia.

Background/Aims: Only a few studies have examined perceptions of the incidence and prognosis of colorectal cancer (CRC) in the general Korean population. The aim of this study was to determine public perceptions of the lifetime incidence rate and survival of CRC. Methods: All adults older than 50 years who visited the Kyung Hee University Hospital at Gangdong were invited to participate in this survey for 5 months in 2021. During the study period, eligible individuals participated in this survey through a link or quick response code on a poster posted in the hospital, which was linked to a web-based questionnaire. The questionnaire used for this survey included demographic and socioeconomic data, perceptions of CRC, and awareness of the CRC incidence and 5-year survival rate. Results: Among 203 respondents, 196 answers were analyzed after the exclusion of seven incomplete answers. In our survey, half of the respondents (49.5%) answered the expected lifetime incidence rate of CRC as 0% to 4.9%. Koreans perceived CRC as a more fatal disease than epidemiological data, as 70.9% of the respondents expected the 5-year survival rate of CRC to be less than 70% for the general population. However, Koreans perceived stage IV CRC as a less fatal disease than epidemiological data, because only 20.9% of the respondents expected the 5-year survival rate of stage IV CRC to be less than 10% for general population. Conclusions Koreans recognized CRC as a more common and fatal disease than actual epidemiological data of CRC. Therefore, more efforts should be made to provide more correct information on CRC for better decision-making and communication.

BACKGROUND: Cerebrovascular accidents after coronary bypass surgery(CBS) are serious and responsible about 10% for postoperative mortality. Recently, the rate of cerebrovascular complication after CBS has increased with increasing number of the operations for high risk patients with old age, hypertension, diabetics and etc. This study was intended to identify the risk factors of cerebrovascular accident after CBS by reviewing the medical records of the patients who underwent CBS. MATERIALS AND METHOD: We reviewed the medical records and statistically analyzed the data of 185 patients who underwent CBS between March 1991 and July 1999. RESULT: The rate of cerebrovascular complication was 7.5%(14 patients) of which there were 5 deaths. Total number of postoperative death was 11 during the same period, and 45.5% of postoperative deaths were associated with cerebrovascular complication. Postoperative arrhythmia(p=0.0064), history of previous CVA(p=0.0090), bypass time(p= 0.0181), atherosclerosis of aorta(p=0.03575) and diabetics(p=0.0452) were statistically related with the development of postoperative cerebrovascular complication. Two patients underwent carotid endarterectomy concomitantly with CBS, neither of them developed cerebrovascular complications. The 3 patients over 75 years did not develop cerebrovascular complication after CBS. CONCLUSION: Risk factors associated with the development of postoperative cerebrovascular complication after CBS were postoperative arrhythmia, history of previous stroke, bypass time, atherosclerosis of aorta and diabetics.

From January 1988 to December 1995, 27 patients, 11 men and 16 women, underwent surgical intervention at our institution for prosthetic valve dysfunctions. The mean age was 43.5+/-12.2 years. Seventeen (63.0%) patients had the mitral valve replacement, 8 (29.6%) the aortic valve, 1 (3.7%) the aortic composite graft, and 1 (3.7%) the tricuspid valve. Mean follow-up period was 49.5+/-30.9 months. In 12 bioprostheses, mean interval between the previous valve replacement and the reoperation was 104.9+/-34.9 months. The causes of redo surgery were structural deterioration of the prosthetic valve (12/12, 100%), paravalvular leak (2/12, 16.7%), and prosthetic valve endocarditis (1/12, 8.3%). In 15 mechanical prostheses, the mean interval was 55.2+/-43.7 months. The causes of redo surgery were pannus formation (8/15, 53.3%), paravalvular leak (4/15, 26.7%), and valve thrombosis (3/15, 20.0%). Posto-perative complications occurred in 7 patients (25.9%). There was no intraoperative death. But one patient, who received mechanical aortic valve replacement died on the 3rd postoperative day due to low cardiac output and multiorgan failure.

PURPOSE: The medial meniscus is injured much more than the lateral meniscus. Because the medial meniscus is much larger in diameter, is thinner in its periphery and narrower in body than the lateral meniscus, and does not attach to either cruciate ligament. We evaluated correlations with sites of tear and history of trauma. METHODS AND MATERIALS: We reviewed retrospectively in 43 patients with meniscal tears on MRI(51 cases) and correlated them with history of trauma. RESULTS: The most common site of injury was the posterior horn of the medial meniscus(32/51), but high incidence of lateral meniscal tear compared with previous reports was seen. In the cases which had history of trauma, the posterior horn of medial meniscus was most commonly injured(26/34) and 5 meniscal tears were combined with meniscal tear in the other site. The tear in the anterior horn of the medial meniscus was seen only in a patient which had history of trauma and combined with meniscal tear in the other site. But in the meniscal tears without definite history of trauma, the incidence of meniscal tear was different from the meniscal tear with history of trauma. The incidence of lateral meniscal tear(11/17) was highter than medial meniscal tear and the posterior horn of lateral meniscus was commonly injured. CONCLUSION: We concluded that the medial meniscus was commonly injured, especially posterior horn, but in the cases which had no definite history of trauma, the lateral meniscus was commonly ipjured. An awareness of prevalent site of meniscal injuries may be helpful in the diagnostic interpretation of MR imaging of knee.
