Successful Tracheal Intubation Using Rigid Video-Stylet in a Ptiaent with Tracheobronchopathia Osteochondroplastica / 계명의대학술지

Tracheobronchopathia osteochondroplastica (TO) is a rare dysplastic disease of the trachea characterized by cartilaginous or bony nodules in the tracheobronchial lumen. Rigid video-stylet is an intubating device that provides favorable conditions even in the difficult cases. In this report, we describe a successful airway management using the rigid video-stylet in a 62-year-old man with unanticipated difficult intubation later diagnosed for TO. He was planned for elective percutaneous nephrolithotomy under general anesthesia. He was healthy without any airway symptoms. With the rigid video-stylet, we not only performed successful tracheal intubation but also examined endotracheal lumen simultaneously. Using the rigid video-stylet, we noticed multiple whitish projecting nodules in the trachea, which were the typical findings for TO.

Effect of Low Dose 5-Fluorouracil and Cisplatin Intra-arterial Infusion Chemotherapy in Advanced Hepatocellular Carcinoma with Decompensated Cirrhosis / 대한간학회지

BACKGROUND/AIMS: Advanced hepatocellular carcinoma (HCC) with portal vein thrombosis (PVT) has a poor prognosis. The aim of this study was to evaluate the efficacy and safety of repeated arterial infusions of low dose cisplatin and 5-fluorouracil (FU) in patients with advanced HCC with decompensated cirrhosis. METHODS: Between January 1995 and December 2003, a total of 79 decompensated cirrhotic patients having HCC and PVT were enrolled and divided into 2 groups. Group 1 (n=40) received intra-arterial infusion chemotherapy with cisplatin (10 mg for 5 days) and 5-FU (250 mg for 5 days) via an implanted chemoport every 4 weeks' and group 2 (n=39) was managed with only conservative treatment. RESULTS: The two groups were well matched with respect to the features relating to the prognosis, including age, gender and the Child- Pugh class. Although diffuse tumor involvement, main portal vein tumor thrombosis and bi-lobar involvement were more frequent in group 1, the median survival period of group 1 was significantly longer than group 2 (5 months vs. 3 months, respectively, P=0.016). Also, the 1-year survival rate of group 1 (7.5%) was higher than that of group 2 (5.1%) (P=0.016). When we analyzed the patients with the Child class B, the survival benefits of intra-arterial chemotherapy were more significant (P=0.008). CONCLUSIONS: Intra-arterial chemotherapy consisting of low dose 5-FU and cisplatin achieved favorable results for advanced HCC patients who had decompensated cirrhosis, and it showed better survival in selected patients. This therapy may be useful as a palliative treatment for HCC patients with decompensated cirrhosis.

Efficacy of AST to Platelet Ratio Index in Predicting Severe Hepatic Fibrosis and Cirrhosis in Chronic Hepatitis B Virus Infection / 대한소화기학회지

BACKGROUND/AIMS: An ideal noninvasive diagnostic test for hepatic fibrosis should be simple, inexpensive, and accurate. We aimed to find the simple marker for predicting hepatic fibrosis and to compare the accuracy of AST, platelet, AST/ALT ratio and AST to platelet ratio index (APRI) in chronic hepatitis B patients without clinical evidence of cirrhosis. METHODS: A total of one hundred and twenty-six chronic hepatitis B patients who underwent liver biopsy at the Ajou University Hospital from August 1998 to December 2003 were enrolled. Hepatic fibrosis was assessed using the Ludwig classification. Significant fibrosis was defined as fibrosis score of 3 or more. The AST/ALT ratio and APRI were calculated and correlations with hepatic fibrosis were analyzed. RESULTS: APRI showed a significant correlation (r=0.501, p=0.000) with hepatic fibrosis, and was superior to AST, AST/ALT ratio and platelet in predicting fibrosis. Patients with significant fibrosis (fibrosis stage 3, 4) can be identified to have APRI=1 with sensitivity 71.2% and specificity 70.3%. The sensitivity and specificity of an APRI = 1.5 for cirrhosis (stage 4) were 83.3% and 75.0%. CONCLUSIONS: Simple index using AST and platelet value can predict the presence of significant fibrosis and cirrhosis in chronic hepatitis B patients without clinical evidence of cirrhosis.

Chronic hyponatremia of Sheehan's syndrome / 대한내과학회지

Sheehan's syndrome has been attributed to ischemic damage of the pituitary gland or hypothalamic-pituitary stalk during the peripartum period. Well-described clinical features of Sheehan`s syndrome include hypothyroidism, growth hormone deficiency, hypogonadism, hypoprolactinemia, adrenal insufficiency, and different sodium and water disturbance. The occurrence of sodium and water disturbances associated with Sheehan`s syndrome depends on the degree of pituitary damage, time of onset since the initial pituitary insult, and concurrent medical conditions that also may play a role in sodium and water balance. Chronic hyponatremia is the most common presentation of altered sodium levels in patients with Sheehan`s syndrome. The chronic nature of the presenting hyponatremia suggests more subtle changes of panhypopituitarism or better adaptive mechanism. Although controversial, another mechanism proposed for hyponatremia in the chronic setting involves alternation in the renin-angiotensin/aldosterone system with resulting sodium wasting. We presented a patient with Sheehan`s syndrome associated with hyporeninemic hypoaldosteronism and hyponatremia 53 years old women, who had 4th baby delivery with severe blood loss about 25 years ago, was admitted to hospital because of general weakness. The patient was diagnosis Sheehan`s syndrome with hyponatremia. In addition, we performed hormonal study to find cause of hyponatremia. The results were hypopituitarism and hyporeninemic hypoaldosteronism. Hyponatremia was corrected by hormonal therapy (glucocorticoid,synthyroid,estrogen). The patient felt well-being sensation and was followed up the out-patient department.
