Almost all colorectal carcinomas have been thought to develop from pre-existing adenomas. However, some colorectal carcinomas can arise directly from normal flat mucosa, and usually form infiltrative mass at the early stage. The carcinogenesis of this infiltrative carcinoma may be different from the well-known adenoma-carcinoma sequence, which usually forms a polypoid mass. The purpose of this study is to investigate the different expression of various oncogenes in polypoid carcinoma and infiltrative carcinoma. We performed immunohistochemical staining on p53, bcl-2, c-erbB-2 and MIB-1 in 29 polypoid carcinomas arised from adenomas, and 21 infiltrative carcinomas. The average tumor size of infiltrative carcinomas (5.5 cm) was larger than that of polypoid carcinomas (3.1 cm), and the polypoid carcinomas were differentiated more than the infiltrative carcinomas. The results of p53, bcl-2, c-erbB-2, and MIB-1 antisera immunoreactivity in the polypoid carcinoma were 79%, 17%, 21%, and 100%, and those in the infiltrative carcinoma were 71%, 29%, 29%, and 100%, respectively. However the diffuse positivities of p53 and MIB-1 antisera were slightly higher in the infiltraive carcinomas (62%, 76%) than in the polypoid carcinomas (55%, 41%) (p=0.63, 0.01). And the results of p53 and c-erbB-2 immunoreactivity in the adenomas were 52% and 17%, respectively, which is significantly lower than that in the polypoid carcinoma(p=0.03, 0.74). The immunoreactivty of bcl-2 in the adenoma was 72%, which was significantly higher than that in the polypoid carcinoma (17%) (p<0.01). In summary, we did not show the significant difference in expression of p53, bcl-2, c-erbB-2, and MIB-1 proteins between polypoid and infiltrative carcinomas. However, the tendency of infiltrative carcinomas having a more aggressive nature suggests another carcinogenetic mechanism is involved in the colorectal carcinogenesis.

BACKGROUND: we have evaluated the association of age, smoking, type of anesthesia, type of operation, duration of surgery, previous history of chronic pulmonary diseases with postoperative pulmonary complications and identified which parameter of preoperative spirometry was a predictor of postoperative pulmonary complications. METHOD: In 270 patients older than 60 years, the postoperative pulmonary complications were evaluated according to age, smoking, type of anesthesia, type of operation, duration of surgery, previous history of chronic pulmonary diseases and the parameters of preoperative spirometry were analyzed. RESULTS: The postoperative pulmonary complications rates were significant higher among patients older than 70 years, and among those with previous chronic pulmonary diseases or their smoking history. The pulmonary complications were increased among patients with general anesthesia or duration of surgery more than 2 hours. The pulmonary complications rates did not differ according to sex, type of operation. The patients with hypercarbia(PaCO2> 45mmHg) have more increased postoperative complications. The preoperative FEVl less than 1 liter, FVC, MMEFR & MVV less than 50% of predicted respectively were predictive of complications. CONCLUSION: Age 70, history of smoking,duration of operation more than 2 hours, general anesthesia, previous chronic pulmonary disease and hypercarbia (> or=45mmHg) on preoperative arterial blood gas analysis were predictivd of pulmonary complications. Among the parameters of spirometry, FEV1, FVC, MMEFR and MVV were indicator of predicting postoperative pulmonary complications.

This study was performed to describe the patterns of healthcare switching with overlapping use of anti-diabetic medication in the elderly using the Korea Health Insurance Review and Assessment Service's claims data. The study subjects were ambulatory elderly diabetic patients (ICD-10, E10-14) receiving at least one oral anti-diabetic drug or insulin, and visiting healthcare facilities more than two times between January and December 2005. A total of 457,975 elderly diabetic ambulatory care patients were identified. The mean of visiting frequencies was 9.0 ( +/- 3.6) and switching frequencies was 1.5 ( +/- 0.8) during 2005. Switching group consisted of 33% of total study subject. Healthcare switching was common in female patients who were older, and had treated polytherapy more in rural areas. The movement among primary care medical services was very common among the patients in the switching group (52.6%). A statistically significant correlation was observed between the healthcare switching and concomitant drug use (rho = 0.96), and overlapping days (rho = 0.57). The use of overlapping anti-diabetic medication increased with the extent of healthcare switching. Further, frequent switching of healthcare between primary clinics was observed. Efforts should be made to establish continuity for the elderly diabetic patients with the identification of frequent switching with overlapping medication.

Thrombotic thrombocytopenic purpura (TTP) and the related hemolytic uremic syndrome (HUS) are disorders characterized by thrombocytopenia, microangiopathic hemolytic anemia, a variable degree of impairment of renal function and fluctuating neurological symptoms, which are thought to be due to platelet activation and subsequent formation of thrombi in the microcirculation. The fact that there was no clear-cut clinical and laboratory features that differentiate HUS from TTP has lead to view these two syndromes as a clinical continuum. Microvascular thrombosis is the typical lesion and closely related with endothelial injury and platelet activation. Pathologic alterations of the brain parenchyma are mainly manifested by small multiple infarcts. Numerous cases of CNS complications of these syndromes have been evaluated by using CT, but few reports have mentioned the MR findings. We experienced a case of TTP-HUS that had clinical features of cortical blindness and the brain lesion was confirmed by MRI showing cerebral infarct at the occipital area but it was reversible course. So we report this case with a brief review of literature.

This study was conducted to investigate disease-modifying antirheumatic drug (DMARD) utilization in Korean elderly patients with rheumatoid arthritis (RA). We used data from January 1, 2005 to June 30, 2006 from the Health Insurance Review and Assessment Service claims database. The study subjects were defined as patients aged 65 yr or older with at least two claims with a diagnosis of RA. DMARD use was compared by the patients' age-group, gender, medical service, and geographic divisions. The patterns of DMARD use in mono- and combination therapy were calculated. RA medication use was calculated by the number of defined daily doses (DDD)/1,000 patients/day. A total of 166,388 patients were identified during the study period. DMARD use in RA patients was 12.0%. The proportion of DMARD use was higher in the younger elderly, females, and patients treated in big cities. Hydroxychloroquine was the most commonly used DMARD in monotherapy, and most of the combination therapies prescribed it with methotrexate. DMARD use in elderly RA patients was noticeably low, although drug prescriptions showed an increasing trend during the study period, clinicians may need to pay more attention to elderly RA patients.

SAPHO syndrome, characterized by synovitis, acne, pustulosis, hyperostosis, and osteitis is rare compared to other spondyloarthropathies. It is also difficult to diagnose, and treatment methods have not yet been fully identified. Approximately 72% of patients are diagnosed with at least one other disease before a final diagnosis of SAPHO syndrome. In addition, SAPHO syndrome is subject to a delayed diagnosis period of 4.5 to 9.1 years. Medications such as non-steroidal anti-inflammatory drugs, disease-modifying anti-rheumatic drugs, and tumor necrosis factor inhibitors are used in treatment of SAPHO syndrome. Bisphosphonate is also used for refractory SAPHO syndrome; however, most reports on this relate to intravenous injection of medication. The authors experienced and subsequently reported on a case involving a patient with SAPHO syndrome accompanied by fracture and infection of the left second finger who was treated with the oral biphosphonate, alendronate.

Although it is difficult to reach a diagnosis in patients who complain of pain or sensitivity to cold in their hands, Raynaud's phenomenon is most often suspected in such cases. Symptoms of Raynaud's phenomenon include pallor, cyanosis, and redness following cold exposure. Glomus tumors can also increase patients' sensitivity to cold. In this case, our patient complained of symptoms indicative of Raynaud's phenomenon. Although treatment of Raynaud's phenomenon improved the symptoms, pain persisted in the fourth finger of the left hand. We diagnosed the patient with a glomus tumor and, after surgical treatment, the patient's symptoms improved. Here, we have also reviewed and discussed a number of reports of glomus tumors associated with Raynaud's disease. Diagnosing a glomus tumor in the hand may take some time, and the diagnosis could be further delayed if accompanied by Raynaud's phenomenon. Although glomus tumors are rare, we suggest that clinical awareness is important for early diagnosis and treatment.

We aimed to determine the characteristic adverse events (AEs) of iodinated contrast media (IOCM) and to compare the safety profiles of different IOCM. This study used the database of AEs reports submitted by healthcare professionals from 15 Regional Pharmacovigilance Centers between June 24, 2009 and December 31, 2010 in Korea. All reports of IOCM, including iopromide, iohexol, iopamidol, iomeprol, ioversol, iobitridol and iodixanol, were analyzed. Safety profiles were compared between different IOCM at the system organ level using the proportional reporting ratio (PRR) and 95% confidence interval (95% CI). Among a total of 48,261 reports, 6,524 (13.5%) reports were related to the use of IOCM. Iopromide (45.5%), iohexol (16.9%), iopamidol (14.3%) and iomeprol (10.3%) were identified as frequently reported media. 'Platelet, bleeding & clotting disorders' (PRR, 29.6; 95%CI, 1.9-472.6) and 'urinary system disorders' (PRR, 22.3; 95% CI, 17.1-29.1) were more frequently reported for iodixanol than the other IOCM. In conclusion, the frequency of AEs by organ class was significantly different between individual media. These differences among different IOCM should be considered when selecting a medium among various IOCM and when monitoring patients during and after its use to ensure optimum usage and patient safety.
