PURPOSE: The aim of this study was to identify clinical predictive factors for tumor response after preoperative chemoradiotherapy (CRT) in rectal cancer. MATERIALS AND METHODS: The study involved 51 patients who underwent preoperative CRT followed by surgery between January 2005 and February 2012. Radiotherapy was delivered to the whole pelvis at a dose of 45 Gy in 25 fractions, followed by a boost of 5.4 Gy in 3 fractions to the primary tumor with 5 fractions per week. Three different chemotherapy regimens were used (5-fluorouracil and leucovorin, capecitabine, or tegafur/uracil). Tumor responses to preoperative CRT were assessed in terms of tumor downstaging and pathologic complete response (ypCR). Statistical analyses were performed to identify clinical factors associated with pathologic tumor response. RESULTS: Tumor downstaging was observed in 28 patients (54.9%), whereas ypCR was observed in 6 patients (11.8%). Multivariate analysis found that predictors of downstaging was pretreatment relative lymphocyte count (p = 0.023) and that none of clinical factors was significantly associated with ypCR. CONCLUSION: Pretreatment relative lymphocyte count (%) has a significant impact on the pathologic tumor response (tumor downstaging) after preoperative CRT for locally advanced rectal cancer. Enhancement of lymphocyte-mediated immune reactions may improve the effect of preoperative CRT for rectal cancer.

Paraformaldehyde has been used in the past as a pulpotomy agent. However, it has a severe cytotoxic effect and may cause alveolar bone necrosis. Depulpin, a devitalizing agent containing 49% paraformaldehyde, is no longer used frequently due to its severe side effects. In the two cases described in the present study, Depulpin was used as a devitalizing agent during root canal treatment. It caused a gradual loss of sensibility in adjacent teeth, gingival necrosis, and osteomyelitis. This case report demonstrates the serious side effects of using a paraformaldehyde-containing paste as a devitalizing agent for pulp, particularly mandibular bone necrosis.

Prostaglandin E1(PGE1) is known to have various physiological action such as vasodilatation, decrease of blood pressure, angiogenesis, inhibition of platelet aggregation and so forth. PGE1 has been developed in many different formulations in order to overcome its chemical instability and deactivation in the lungs when administered parenterally. Lipo-AS013 is a potent drug with higher chemical stability and greater vascular wall targeting than others. The study was done on 3x10 cm model flap of dorsal skin of Sprague-Dawley rats and the flap perfusion survival were observed and documented. The flap treated with Lipo-AS013 beforehand was given intravenously Sodium fluorescein 10 minutes later, and then Percent Dye Fluorescence Index(% DFI) was calculated. The results were compared to a control group and the group administered locally epinephrine. In the control group, the % DFI and flap survival rate increased from 54.1+/-6.7 to 65.0+/-2.6(p<0.01) while in Lipo-AS013 group from 55.3+/-2.2 to 67.4+/-1.9(p<0.01), respectively. In the epinephrine group, the % DFI(p<0.05) and flap survival rate(p<0.001) decreased. In the both epinephrine and Lipo-AS013 group Percent DFI and flap survival rate are comparable with the control group. The result indicates that the potent Lipo-AS013 enhances the blood flow and flap survival. This highly potent Lipo-AS013 may have targeting ability and accumulate PGE1 onto the vascular walls. A quantitative analysis of fluorescence on the skin surface is a reliable tool to measure the blood perfusion into an ischemic flap and its viability. Further comparative study with conventional PGE1 and Lipo-PGE1 is needed in order to clarify the action and efficiency of Lipo-AS013.

The aim of this case report is to draw the attention to the occurrence of cystic fibrosis (C.F.) in a Korean infant and thus increase the awareness for the diagnosis. The male infant was presented with a history of recurrent bronchiolitis manifested by severe cough, wheeze and dyspnea from three weeks of age, in whom the diagnosis of C.F. was clinically suspected and was confirmed by demonstration of two elevated sweat chloride levels (97 mEq/L and 99 mEq/L) in the patient. The diagnosis was delayed because the main manifestations of C.F. were the same as the main symptoms of common diseases such as cough, diarrhea and failure to thrive. C.F. is probably underdiagnosed in Korean population both because the diagnosis is not considered since the disease is thought to be uncommon or even not to occur and because diagnostic facilities including the quantitative iontophoresis sweat test are lacking.

The coronary vasospasm has usually been readily reversible by sublingual, intravenous or intracoronary nitroglycerin. Relief of spasm, either spontaneous or following nitrate therapy, results in reperfusion. Occurence of ventricular tachyarrhythmia during release of coronary spasm is attractive as a possible cause of sudden death because of significant proportion of sudden death victims do not have acute myocardial infarction. Recently, we experienced a 36 year old man who developed spontaneous coronary vasospasm, and the patients suffered from repetitive reperfusion ventricular tachyarrhythmia, and died suddenly in spite of administration of isosorbide dinitrate, lidocaine and several trials of cardioversion and cardiopulmonary resuscitation, and we report.
