Torsion of a mucocele of the vermiform appendix is an extremely rare condition and also a rare cause of an acute abdomen with a clinical presentation that is indistinguishable from acute appendicitis, and thus, the condition is diagnosed during operation. Here, the authors describe the case of a 78-year-old female, who presented with intermittent abdominal pain. The appendix had a pelvic position and the torsion was counterclockwise. In addition, the torsion was associated with mucocele of the appendix, which was considered a secondary factor of torsion. Appendectomy and drainage were performed.

Somatic mutations that lead to hyperactivation of epidermal growth factor receptor (EGFR) signaling are detected in approximately 50% of lung adenocarcinoma in people from the Far East population and tyrosine kinase inhibitors are now the standard first line treatment for advanced disease. They have led to a doubling of progression-free survival and an increase in overall survival by more than 2 years. However, emergence of resistant clones has become the primary cause for treatment failure, and has created a new challenge in the daily management of patients with EGFR mutations. Identification of mechanisms leading to inhibitor resistance has led to new therapeutic modalities, some of which have now been adapted for patients with unsuccessful tyrosine kinase inhibitor treatment. In this review, we describe mechanisms of tyrosine kinase inhibitor resistance and the available strategies to overcoming resistance.

When ultrasound or computed tomographic (CT) scans demonstrate a focal mass within the pancreas, the radiologist or gastroenterologist assumes that it is carcinoma. Statistically this is the correct diagnosis. However, distinguishing pancreatitis from carcinoma by ultrasound and CT is occassionally impossible. Similarly, abnormalities seen on ERCP, such as simultaneous obstruction of both the common bile duct and adjacent pancreatic duct (double duct sign), has been shown to occur in pancreatitis as well as in the more commonly diagnosed pancreatic carcinoma. We experienced 3 cases af focal pancreatic masses that mistaken a carcinoma. And so, knowledge that such a mass can be benign in a clinical setting sbould result in an organiged approach to the correct diagnosis and avoidance of any unnecessary operations.

Benign lichenoid keratosis is an asyrnptomatic, isolated, plaque-like lesion frequently mistaken for basal cell carcinoma, Bowens disease, and actinic or seborrheic keratosis because of its variable clinical appearance. We present two cases of benign lichenoid keratosis. The first case was a 44-year-old female who had mild pruritic, ll x15rnrn sized, single, slightly elevated brownish plaque with fine scaling on the right zygornatic area of 5 years' duration. The second case was a 35-year-old female who had mild prutitic, single, pea- sized erythernatous patch on the left ala nasi of one month's duration. On histologic examination, these two cases showed same histologic findings, such as focal parakeratosis, moderate hyperkeratosis, irregular acanthosis and liquefaction degeneration of basal cells in the epidermis and band-like mononuclear infiltration and colloid bodies in the dermis.

BACKGROUND: Intra-aortic balloon pump (IABP)is well known for its hemodynamic benefit but still has its own complications.Proper use of IABP is the best way t o obt ai n maximum benefit with low complication rate. MATERIALS AND METHOD: Twenty one(men 10,female 11) patients were included in this study among the 100 consecutive adult cardiac surgery patients in our hospital.Eighteen(85.7%)were ischemic heart disease patients.They all received IABP therapy due to postcardiotomy cardiogenic shock according to the well-known indications.Their preoperative conditions,intraoperative factors including hemodynamics, postoperative conditions and IABP-related complications were analyzed. RESULT: Nineteen patients(90.5%)were successfully weaned from IABP.There were 2 patients of operative death and the mortality rate was 9.5%.Duration of IABP use was 40.7+/-24.3 hours.There were 2 cases(9.5%)of IABP-related vascular complications that required surgical intervention. CONCLUSION: We concluded that IABP could be used effectively and safely for postcardiotomy cardiogenic shock patients with low complication rate.

Cancer tissues are characterized by increased glucose uptake. 18F-fluorodeoxyglucose(FDG), a glucose analogue is used for the diagnosis of cancer in PET studies. This study was aimed to compare the glucose uptake and glucose transporter l(GLUT1) expression in various human colon cancer cells. We measured FDG uptake by cell retention study and expression of GLUTI using Western blotting. Human colon cancer cells, SNU-C2A, SNU-C4 and SNU-C5, were used. The cells were incubated with 1micro Ci/ml of FDG in HEPES-buffered saline for one hour. The FDG uptake of SNU-C2A,SNU-C4 and SNU-C5 were 16.8+/-1.36, 12.3+/-5.55 and 61.0+/-2.17cpm/microgram of protein, respectively. Dose-response and time-course studies represent that FDG uptake of cancer cells were dose dependent and time dependent. The rate of FDG uptake of SNU-C2A, SNU-C4 and SNU-C5 were 0.29+/-0.03, 0.21+/-0.09 and 1.07+/-0.07cpm/min/microgram of protein, respectively. Western blot analysis showed that the GLUT1 expression of SNU-C5 was significantly higher than those of SNU-C2A and SNU-C4. These results represent that FDG uptake into human colon cancer cells are different from each other. In addition, FDG uptake and expression of CLUT1 are closely related in human colon cancer cells.
