PURPOSE: Colorectal surgery, there are many important prognostic factors---depth of invasion, lymph node metastasis and distant metastasis. In there, the involvement of the lymph nodes by metastatic colorectal carcinoma may depends on several factors such as the sex, the age of the patient, tumor site and size, the symptomatic duration of the disease, tumor cell differentiation, and operating methods. In that point of view, we want to know how many lymph nodes are dissected for enough to determine statistically considerated Dukes C stage. METHODS: We had studied 128 operation cases of colorectal adenocarcinoma from our hospital admission during the period of May, 1988 to October, 1997 to determine to provide an accurate assessment of the presence of nodal metastases. Patients status, tumor site and size, symptomatic duration of disease, tumor cell differentiation, and operating methods of 128 cases were analyzed. We calculated the probability to find at least one positive node in Dukes C, by binomial distribution from SPSS (version 7.5). RESULTS: Eighty-three specimens (65%) were classified as Dukes B. Forty-five specimen (35%) had lymph node metastases (Dukes C) with a mean of 4.1+/-4.1 positive lymph nodes per specimen. The mean total number of lymph nodes identified per specimen was 11.6+/-7.4 (range 1~41), Dukes B was 10.9+/-7.1 (range 1~29) and Dukes C was 12.8+/-7.9 (range 3~41). Applying Students t-test to compare two independent average means, the result was the absence of significant differences in the number of nodes for the specimens defined as Dukes B and Dukes C, sex, age, symptom duration, and operationmethods whereas significant differences did exist for the specimen depending on the tumor differentiation, tumor size, and location. Poorly differentiation cancer was more prominent meaning than well or moderately differentiation in Dukes B (p<0.05). In stage Dukes C, if tumor size was below 2cm it was differences in other sizes (p<0.05). In tumor location, if tumor sited ascending colon was more prominent than sigmoid and rectum (p<0.05). According to our result, minimum 6 lymph nodes per specimen were optimal Dukes C staging assessment. CONCLUSION: The minimum 6 lymph nodes provided an accurate assessment of the presence of nodal metastases (95 percent confidence interval) in Dukes C stage.

Idiopathic renal hypouricemia (iRHUC) is a rare hereditary disease caused by a defect in urate handling of renal tubules. Type 1 renal hypouricemia (RHUC1) is diagnosed with confirmation of a mutation in SLC22A12 gene which encodes a renal urate-anion exchanger (URAT1). The majority of iRHUC patients are asymptomatic, especially during childhood, and thus many cases go undiagnosed or they are diagnosed late in older age with complications of hematuria, renal stones, or acute kidney injury (AKI). We report a case of a 7-year-old boy with subtle symptoms such as general weakness and dizziness and revealed hypouricemia and incidental nephrolithiasis. Homozygous mutations were detected in the SLC22A12(c.774G>A) by molecular analysis. The present case suggests that fractional excretion of uric acid (FEUA) screening could be better followed by the coincidental discovery of hypouricemia, to prevent conflicting complications of iRHUC, even with normal urine uric acid to creatinine ratio (UUA/UCr), and sequential genetic analysis if needed.

Thyroid papillary cancer is the most common type of thyroid cancer and the incidence rate is 70-80% of entire thyroid cancer. 10-year survival rate is more than 90%. It is mostly irregular marginated- hard mass but, may have cystic property. The most common clinical symptom is silent neck mass, but rapid growth or local invasion may develope the symptoms such as pain, hoarseness, dysphagia, hemoptysis and dyspena. With the 10% of invasion rate, it spreads to adjacent muscle, recurrent laryngeal nerve, pharynx, larynx, trachea, esophagus and spinal cord. We report a case of acute airway obstruction due to intracystic hemorrhage of thyroid papillary cancer which invades the retropharynx.

Background and Objectives: Vascular smooth muscle cell (SMC) proliferation and migration play a critical role in neointimal formation. Focal adhesion is involved in cell proliferation and migration, and talin is known to be a key regulator of these processes. We synthesized a new talin modulator that binds to the talin protein, and investigated its effects on SMCs and neointimal formation after vascular injury. Methods: Human aortic SMCs (HAoSMCs) were treated with a newly synthesized talin modulator. Apolipoprotein E knockout (ApoE KO) mice were subjected to left femoral arterial injury and orally administered with the talin modulator daily. Laser Doppler imager was used to compare the blood flow, and injured femoral arteries and blood serum were analyzed after 28 days. Results: The talin modulator significantly inhibited cell proliferation in a concentration-dependent manner and suppressed the migration of HAoSMCs. Treatment with a talin modulator resulted in a significant reduction in the phosphorylation of focal adhesion molecules and downstream signaling molecules related to cell proliferation and migration. The effects of the talin modulator in HAoSMCs were found to be reversible, as evidenced by the reactivation of signaling pathways upon its removal. After 28 days of administration of the talin modulator, an improvement in the blood flow and reduction in neointimal formation in the injured femoral arteries were observed. Conclusions We demonstrated the inhibitory effects of a talin modulator on SMC proliferation and migration, and that were associated with downregulation of signaling pathways, resulting in the attenuation of neointimal formation in ApoE KO mice.

In an attempt to clarify the relationshop between left ventricular function and chronic obstructive pulmonary disease(COPD), systolic time intervals were measured in 79 control subjects and 60 patients with COPD who had no evidence of organic heart disease. The patients with COPD were divided into three groups based on the percent predicted forced expired volume in one second. Significant differences in pre-ejection period index(PEPI) and left ventricular ejection time index(LVETI) existed between the control subjects and the patients with the most severe lung disease(Group III). A highly significant difference in PEP/LVET existed between these two groups. The abnormalities of systolic time intervals demonstrated in these patients are characteristic of left ventricular dysfunction and indicate that left ventricular dysfunction is frequently present in patients with moderate obstructive lung disease.
