PURPOSE: Obesity in children and adolescence is highly correlated with adult obesity, which can provoke hypertension. Therefore, it is important to evaluate the blood pressure of obese children regularly. In this study, the results of ambulatory blood pressure monitoring (ABPM) in obese children and adolescents were evaluated. METHODS: ABPM was conducted for selected patients who visited Handong University Sunlin Hospital from Feb. 1, 2006 to Dec. 1, 2007. The patients were classified into 3 groups: group 1 was normal, group 2 had normal casual blood pressure and a body mass index over the 95th percentile, and group 3 had high casual blood pressure over 120/80 mm Hg and a body mass index over the 95th percentile. Systolic and diastolic 24-hour blood pressure was measured, including both day and night. RESULTS: There were 49 patients in the study. The results showed a significant difference for average systolic blood pressure between the three groups (105.1+/-4.7, 111.0+/-7.1, 117.8+/-6.6 mmHg, P<0.001), but for average diastolic blood pressure only between groups 1 and 3 (69.1+/-5.3, 77.9+/-6.3 mmHg, P=0.001). In the daytime, only groups 1 and 3 showed a statistically significant difference for systolic and diastolic blood pressure. During the night the systolic pressure of group 3 was significantly higher than the other groups, but the diastolic pressure of group 3 was only higher than that group 1. No statistical difference was found in night dips among the groups. CONCLUSION: Ambulatory blood pressure monitoring in children and adolescents showed statistically higher blood pressure in obese patients with high casual blood pressure.

Recently microvascular decompressive approach to the hyperactive type of low cranial nerves dysfunction has been popular procedures in neurosurgical operation. The neurosurgical teams at St. Paul's Hospital, Catholic Medical College operated on 11 patients employing this technique for 2 years. The patients were diagnosed as 9 patients with hemifacial spasm, one with trigeminal neuralgia, and one with glossopharyngeal neuralgia. The results were very encouraging of the 10 patients. But remaining one patient was failed with therapy. The authors would like to share with you their experiences employing the microvascular surgical technique, the results & the prognosis.

Blue Rubber Bleb Nevus syndrome, or Bean's syndrome is a very rare disease characterized by an association of 1) hemangioma cutis in which the nevi feel like rubber blebs; 2) hemangiomas of the digestive organs; 3) iron-deficiency anemia due to hemorrhage from the digestive tract. Sometimes, the bleeding is so severe and massive that the patient needs blood transfusions and/or emergency operations. We present a 29-year-old man with Blue Rubber Bleb Nevus syndrome. This patient was admitted to out hospital due to recently aggrevated dizziness and intermittent rectal bleeding. Multiple bluish tumors were noted on the palm, sole and glans penis. Laboratory examination revealed severe iron-deficiency anemia. Barium studies revealed multiple polypoid masses in the stomach, small bowel and colorectum. On esophagogastroduodenoscopy and colonoscopy, three or four dozens of hemangiomas with variable size and shape were noted in the stomach, duodenum at or around the ampulla of Vater and colorectum. This patient was of particular interest because rectal bleeding occurred from rectal lesion which protruded out of anus and caused bleeding during defecation, and which showed as a 2.0 cm Yamada type III polypoid lesion. Endoscopic ultrasonography confirmed us that this lesion was confined to the mucosa and submucosa without extension into muscle layer. Endoscopic polypectomy of this lesion was performed because which considered as the main focus of current rectal bleeding. He was discharged without any complication and 4 months later, he was well without rectal bleeding and his hemoglobin level increased upto 13.5 g/dl. To our knowledge, this is the first case of Blue Rubber Bleb Nevus syndrome in Korea.

Cell survival is the result of a balance between programmed cell death and cellular proliferation. Cell membrane receptors and their associated signal transducing proteins control these processes. Of the numerous receptors and signaling proteins, epidermal growth factor receptor (EGFR) is one of the most important receptors involved in signaling pathways implicated in the proliferation and survival of cancer cells. EGFR is often highly expressed in human tumors including oral squamous cell carcinomas, and there is increasing evidence that high expression of EGFR is correlated with poor clinical outcome of common human cancers. Therefore, we examined the antiproliferative activity of gefitinib, epidermal growth factor receptor tyrosine kinase inhibitor (EGFR TKI), in head and neck cancer cell lines. SCC-9, KB cells were cultured and growth inhibition activity of gefitinib was measured with MTT assay. To study influence of gefitinib in cell cycle, we performed cell cycle analysis with flow cytometry. Western blot was done to elucidate the expression of EGFR in cell lines and phosphorylation of EGFR and downstream kinase protein, Erk and Akt. Significant growth inhibition was observed in SCC-9 cells in contrast with KB cells. Also, flow cytometric analysis showed G1 phase arrest only in SCC-9 cells. In Western blot analysis for investigation of EGFR expression and downstream molecule phosphorylation, gefitinib suppressed phosphorylation of EGFR and downstream protein kinase Erk, Akt in SCC-9. However, in EGFR positive KB cells, weak expression of active form of Erk and Akt and no inhibitory activity of phosphorylation in Erk and Akt was observed. The antiproliferative activity of gefitinib was not correlated with EGFR expression and some possibility of phosphorylation of Erk and Akt as a predictive factor of gefitinib response was emerged. Further investigations on more reliable predictive factor indicating gefitinib response are awaited to be useful gefitinib treatment in head and neck cancer patients.
