OBJECTIVE: A general orientation along the cervical spine could be estimated by external landmarks, and it was useful, quick and less exposable to radiation, but, sometimes it gave reference confusion of target cervical level. The authors reviewed the corresponding between the neck external landmarks and cervical levels. METHODS: Totally 1,031 cervical lateral radiographs of different patients were reviewed in single university hospital. Its compositions were 534 of males and 497 females; 86 of second decades (10-19 years-old), 169 of third decades, 159 of fourth decades, 209 of fifth decades, 275 of sixth decades, and 133 of more than seventh decades (>60 years-old). Reference external landmarks (mandible, hyoid bone, thyroid cartilage, and cricothyroid membrane) with compounding factors were reviewed. RESULTS: The reference levels of cervical landmarks were C2.13 with mandible angle, C3.54 with hyoid bone, C5.12 with thyroid cartilage, and C6.01 with cricothyroid membrane. The reference levels of cervical landmarks were differently observed by sex, age, and somatometric measurement (height) accordingly mandible angle from C1 to C3, hyoid bone from disc level of C2 and C3 to C5, thyroid cartilage from disc level of C3 and C4 to C7, and cricothyroid membrane from C4 to disc level of C7 and T1. CONCLUSION: Surface landmarks only provide general reference points, but not correspond to exact levels of the cervical spine. Intraoperative fluoroscopy ensures a more precise placement to the targeted cervical level.

Capsule endoscope is self-contained videoendoscopy device that transmit images of the gastrointestinal tract to an external receiver. Capsule endoscopy has become a very important tool for diagnosing of small bowel disorders. Upcoming capsule endoscopy techniques for the investigation of esophageal, stomach, and colon may render it promising technique for these organs as well. This document is intended to provide the principles by which credentialing organizations may create practical guidelines for granting privileges to perform capsule endoscopy. KSGE recommends that the use of capsule endoscopy be limited to practitioners already competent and privileged to perform standard upper and lower endoscopy and who have extensive experience viewing gastrointestinal mucosa. KSGE recommends additional specific training in capsule endoscopy as well as review of the 20 procedures to verify competence. KSGE also admitted formal fellowship training having a familiarity with the hardware and software systems and interpretation of the at least 10 cases under the supervision of professor in capsule endoscopy during GI fellowship.

OBJECTIVE: Homeostasis of the extracellular matrix (ECM) is maintained by the action of a specific system of proteolytic enzymes known as matrix metalloproteinases (MMP) and tissue inhibitors of metalloproteinases (TIMP). The MMP/TIMP system regulates the composition and turnover of ECM to control the site and extent of connective tissue remodeling. In pathologic conditions, MMP play a key role in degradation of basement membrane and extracellular matrix, and is responsible for cancer invasion, progression and metastasis. The aim of this study is to evaluate the correlation between expressions of MMP/TIMP and clinicopathologic factors in endometrial cancer. METHODS: Expressions of MMP-2, MMP-9, TIMP-1, and TIMP-2 were assessed by immunohistochemistry in a total of 55 endometrial cancers and were analyzed by the correlation between expressions of MMP/TIMP and clinicopathologic factors in endometrial cancer. RESULTS: Expression rates of MMP-2,-9, TIMP-1, and TIMP-2 were 71.7%, 54.9%, 41.2%, and 76.5% respectively. Expression of MMP-2 was correlated with the group of positive lymph node metastasis in endometrial cancer (p=0.04). Specially, coexpression of MMP-2 and TIMP-2 was significantly more frequent in the group of positive lymph node metastasis (p<0.01) and the group of positive peritoneal CONCLUSION: The expressions of MMP and TIMP were not a significant difference in survival analysis, but this study was recognized that the coexpression MMP-2 and TIMP-2 is correlated with lymph node metastasis and positive peritoneal cytology.

OBJECTIVES : Impaired autonomic function in patients with chronic renal failure has been well documented in a number of studies to assess the degree of cardiovascular autonomic dysfunction and to assess the relationship with plasma catecholamines. The purpose of the present study was to evaluate the prevalence of autonomic dysfunction and to determine the effect of autonomic dysfunction on the increment of plasma catecholamine, dialysis-induced hypotension and hypotension during chronic dialysis. METHODS: We measured the degree of autonomic damage and the concentration of plasma catecholamines in 20 patients on maintenance hemodialysis, 12 pre- dialysis patients with chronic renal failure and 20 normal controls using a standardized battery of five cardiovascular reflex tests. RESULTS: 1) In normal controls, 70% of cases had a normal or early parasympathetic abnormalities however in patients with chronic renal failure, 45.2% of patients had severe abnormalities. The prevalence of autonomic dysfunction was 62.5% and there was significant correlation between sympathetic and parasympathetic score in patients with chronic renal failure. 2) Although overall autonomic function was not different in two chronic renal failure groups, the magnitude of heart rate response to Valsalva maneuver was increased and the magnitude of fall of blood pressure in response to standing-up was reduced in dialyzed patients compared with nondialyzed patients. 3) Patients with autonomic dysfunction was older and had higher postdialysis concentration of plasma norepinephrine than those with normal autonomic function. 4) In dialyzed patients, predialysis concentration of plasma norepinephrine at rest varied widely and was significantly related to the duration of dialysis. Postdialysis concentration of norepinephrine was significantly correlated with the degree of parasympathetic damage. 5) There were no significant differences in autonomic damage or plasma catecholamines whether dialysis- induced hypotension and hypotension in chronic hemodialysis or not. CONCLUSION : Disturbances of autonomic nerve system are common in chronic renal failure with distinct abnormalities of parasympathetic function and additional sympathetic dysfunction. Elevated plasma norepinephrine seems to be related to the compensatory response of sympathetic nerve system to parasympathetic damage. Impairment of autonomic function does not appear specifically related to dialysis-induced hypotension or hypotension in chronic dialysis.

OBJECTIVE: Left ventricular hypertrophy is common and major complication in patients with end stage renal disease (ESRD), but pathogenesis is not clear. We have used echocardiography to evaluate influential factors and contractile performance according to the geometry of left ventricle. METHODS: We measured left ventricular mass, the extent of pericardial effusion and systolic function of left ventricle with M-mode and two dimensional echocardiography in 99 cases of ESRD from March 1993 to March 1996. RESULTS: 1) Body surface area and systolic blood pressure was higher in men than those in women. But, there was no difference in LV mass index or systolic function between the sex. 2) Among the 99 patients with ESRD, 89 cases (90%) had increased ventricular mass and 10 cases had normal ventricular mass. In the left ventricular hypertrophy groups, 60 cases had concentric hypertrophy, 29 cases had eccentric hypertrophy. 3) In patients with normal ventricular mass, hypertension and pericardial effusion were less frequent than in those with left ventricular hypertrophy. In patients with concentric hypertrophy, systolic blood pressure and body surface area were increased and serum albumin was decreased as compared to patients with eccentric hypertrophy. In patients with eccentric hypertrophy, duration of dialysis was increased. But, the result of Logistic analysis showed that systolic blood pressure and serum albumin were reliable factors for the geometry of left ventricle. 4) In patients with eccentric hypertrophy, LV mass index was significantly correlated with the concentration of serum alkaline phosphatase and phosphate. But, in patients with concentric hypertrophy, any factors were not correlated with LV mass index. 5) Systolic performances such as ejection fraction and fractional shortening were decreased in patients with eccentric hypertrophy. 6) The pattern of left ventricular hypertrophy was not different among non-dialysis group, hemodialysis group and CAPD group. CONCLUSION: In patients with ESRD, left ventricular hypertrophy is a common complication and most common hypertrophic type is concentric hypertrophy. The geometry of left ventricular hypertrophy may be influenced by various factors such as systolic blood pressure and serum albumin concentration and influence on the systolic performance of left ventricle. Further study for the geometry of left ventricle and the prognosis may be necessary for the improvement of cardiovascular complications in patients with ESRD.

PURPOSE: We examined the expressions of claudin-4 and E-cadherin, which are known as cell adhesion-associated proteins, in stomach cancer. The relationship of their expression with the clinicopathologic factors was examined to investigate the roles of these proteins in the invasion or metastasis of stomach adenocarcinoma. METHODS: The expressions of claudin-4 and E-cadherin were examined in 73 cases of adenocarcinoma of the stomach by performing immunohistochemical staining. RESULTS: The expressions of claudin-4 and E-cadherin in the stomach adenocarcinoma were both correlated with the histologic grade, the T-stage and nodal metastasis, respectively (P<0.05). The expression of claudin-4 was significantly associated with the expression of E-cadherin. CONCLUSION: Our data suggests that claudin-4 and E-cadherin are involved in the processes of histologic differentiation, invasion and metastasis of stomach adenocarcinoma.

In diabetic patients who were being treated with hemodialysis, coma and other neurological deficits did not occur in spite of extremely elevated serum glucose levels. In this report, we compared diabetic patients with renal failure in severe hyperglycemia with nonketotic hyperosmolar coma patients with normal renal function to know what affect mental changes. Mental changes were not present in diabetic patients with renal failure. These patients with renal failure showed more severe hyperglycemia, but corrected serum sodium concentration and calculated effective serum osmolality were low. So it is suggested that corrected serum sodium concentration and effective serum osmolality are more important factor affecting mental changes than high blood glucose levels in diabetic patients with renal failure, due to absence of osmotic diuresis.
