A 46-year-old male patient had recurrent episodes of generalized pruritic wheals during hemodialysis. He has experienced urticaria during hemodialysis whenever he used a capillary dialyser sterilized by ethylene oxide(EO, Polysulfone-) gas which is used to sterilize hemodialysers and other medical equipment. On the other hand, capillary dialyser sterilized by Gamma ray (Hemophad) has not evoked urticaria. Although the presence of EO-specific antibodies was not detected, urticarial rash never developed when the equipment was switched to a gamma-sterilized one. We herein report a case referred to ethylene oxide induced cutaneous hypersensitivity during hemodialysis.

BACKGROUNDS: The inflammatory reaction after cerebral ischemia involving adhesion molecules aggravates neurologic deficit. This study aimed to study the change of plasma level of the adhesion molecules after acute cerebral ischemia. METHODS: Nineteen patients with acute cerebral infarction and ten control subjects without a history of cerebrovascular disease were included in this study. The patient groups were subgrouped into large artery atherosclerosis and small artery occlusion groups according to TOAST classification. Plasma levels of sP-selectin, sE-selectin, sICAM-1 and sVCAM-1 were measured within 24 hours and in 6 to 8 days after acute ischemic infarction. RESULTS: The plasma level of sP-selectin was elevated in acute stroke patients within 24 hours and in 6 to 8 days after stroke onset compared with control group(p<0.05). But plasma levels of sE-selectin, sICAM-1 and sVCAM-1 were not different from those of control group. The plasma level of sP-selectin was significantly elevated in large artery artherosclerosis group compared with control group. CONCLUSION: This study suggest that P-selectin actively involves in inflammatory process after acute ischemic stroke, especially associated with atherosclerosis.

Although dural arteriovenous malformations(DAVM) involving the occipital lobe can be the cause of variable posi-tive visual phenomena, the mechanism of these visual disturbances is not fully understood. We report a 42-year-old man with a left occipital DAVM presenting headache and positive visual phenomena in the right hemianopic field. Occipital DAVM was not accompanied by parenchymal lesions in a brain magnetic resonance imaging. The cerebral angiography demonstrated the retrograde flow into the dilated occipital cortical veins as well as the left occipital DAVM having multiple arterial feeders and the drainage into the left transverse sinus. All clinical symptoms disap-peared after a transarterial embolization. Brain 99mTc-ECD single photon emission computed tomography also showed the improvement of hypoperfusion on the left occipital area after the embolization. We believe that the venous hyper-tension by occipital DAVM impeding the perfusion to the occipital lobe plays an important role in producing positive visual phenomena on the hemianopic field.

Obesity is one of the well-known risk factors of breast cancer. We evaluated the relationship between serum adiponectin and resistin levels and breast cancer risk in 41 biopsy-proven breast cancer patients and 43 age- and body mass index-matched controls. The mean serum adiponectin level was lower in the breast cancer group than the control group (6.93+/-3.2 microgram/mL, vs. 7.60+/-3.5 microgram/mL), but this difference did not reach statistical significance (p=0.37). There was a statistically significant difference in serum resistin levels between the groups (breast cancer group 5.23+/-6.9 ng/mL vs. control 1.46+/-2.0 ng/mL; p<0.001). The risk of breast cancer was significantly increased in the highest tertile group for serum resistin level compared to the lowest tertile group (adjusted odds ratio 2.77 [95% CI 1.40-5.50]). The lymph node metastasis was significantly increased in the patients with less than the median adiponectin level (p=0.017). In the patients whose resistin level was higher than the median, the frequency of tumor with the highest histological grade was significantly increased (p=0.025). In conclusions, both the low serum adiponectin levels and high resistin levels are likely to be associated with increased breast cancer risk in Korean women.

STUDY DESIGN: Retrospective study. OBJECTIVES: This study was conducted to evaluate the effects of using an epidural steroid sponge for postoperative pain control in lumbar discectomy. SUMMARY OF LITERATURE REVIEW: There are many methods to control postoperative pain after lumbar discectomy, including opioid analgesics, epidural catheters, and epidural steroid Gelfoam sponges. MATERIALS AND METHODS: A total of 72 patients who underwent surgery between March 2011 and February 2014 were enrolled. Their average age was 54 years (range, 24–82 years). In group A (35 patients), Gelfoam was inserted after being soaked with a solution of 2% lidocaine (400 mg/20 mL; 1 vial) and dexamethasone (5 mg/mL; 1 ampoule). In group B (37 patients), it was inserted after soaking with normal saline. Postoperative pain was assessed by visual analogue scale (VAS) scores. Pain above 5 points was controlled by a narcotic analgesic agent, and the duration and number of postoperative interventions, the period of time before walking after the operation, and the period until the date of discharge after surgery were assessed and compared. The Mann-Whitney U test was used as a nonparametric method. P-values less than 0.05 were considered to indicate statistical significance. RESULTS: In group A, 15 patients did not require analgesics on the day of surgery. In 20 patients, no analgesics were needed on postoperative day (POD) 1. In group B, 8 patients on the day of surgery and 13 patients on POD 1 did not require analgesics. In group A, 26 patients were able to walk on the day of surgery, and all patients were able to walk on POD 1. In group B, 19 patients was able to walk on the day of surgery and all patients were able to walk on POD 1. The mean number of hospital days before discharge was 6.3 in group A and 8.2 in group B. CONCLUSIONS: By continuously releasing low doses of steroids into the epidural space, this technique provided satisfactory results for postoperative pain control.

PURPOSE: To introduce the history and principle mechanism of electrochemical treatment (EChT) with animal study and report two cases successfully treated breast cancer and hemangioma by EChT. METHODS: In animal study, the breast cancer tumor in nude mouse treated with EChT (100 Coulomb/cm3) were reviewed for histologic changes. In the case studies, we reported method of EChT and clinical results after EChT. Case 1: 74 yr old female with locally advanced breast cancer received 3 times EChT with 1,000 Coulomb/time, 8 Volt. Case 2: 51 yr old female with breast hemagioma received one time EChT with 80 Coulomb, 8 Volt. RESULTS: In animal study, There were destructive change including vaculated cell fragment and extensive coagulative necrosis. Case 1 showed no local recurrence during 18 monthes after EChT. Case 2 also showed no evidence of recurrence of hemangioma. CONCLUSION: The EChT is easy to use. It is effective, safe, less traumatic and makes patients recover quickly. This is a new and effective method to treat patients with tumours that are inoperable and can not receive chemotherapy or radiotherapy.

STUDY DESIGN: Retrospective study. OBJECTIVES: We reported the therapeutic usefulness of a selective nerve root block (SNRB) for patients with a single level spinal stenosis. SUMMARY OF LITERATURE REVIEW: Selective nerve root block for the radiculopathy due to lumbar disc herniation, spinal stenosis, and spondylolisthesis have been reported frequently. MATERIALS AND METHODS: We retrospectively examined 44 patients with single-level spinal stenosis, for whom surgical treatment was considered due to the failure of other conservative treatments from January 2005 to January 2010. All 44 patients were admitted for surgical decompression. Selective nerve root block was done just before a final decision of surgical procedure; patients with his or her 50% or more pain reduction could avoid surgery. RESULTS: In fourty-four cases, twenty-seven pateints underwent a surgical operation. Seventeen patients avoided surgical procedures by successful SNRB. As a result of a 3 year follow-up, the VAS score was significantly and continuously low on the operation group (p=0.02~0.03). K-ODI and Roland-Morris Disability scores were low in both groups until 1 year after the operation and SNRB procedure (p=0.026~0.042, p=0.03), but there was no statistically significant difference beteween the two groups after 2 years upon follow-up (p=0.072~0.14, p=0.06). Generally, the operation group had good results until 1 year after operation and had better tendency for improvement. The data displayed a high probability of surgical treatment among the patients with foraminal stenosis (p=0.039) highlight - this sentence says there is no difference after 1 year and there is still no difference after 2 years. If this is true, the sentence needs to be rewritten so that it says both times show no difference. If there is a difference between 1 year and 2 year then the sentence needs to be rewritten to make this more clear. The next sentence seems to say they are different. CONCLUSIONS: Selective nerve root block avoided the surgical intervention in 39% of the patients with the spinal stenosis refractory to the conservative treatment. Thus it is one of options for the refractory spinal stenosis.

PURPOSE: The relatively low incidence of breast cancer in Asian countries with cultures which traditionally eat a large amount of soy is worth noticing in research fields. Genistein is a isoflavone phytoestrogen found in soy and its consumption may have a role in cancer etiology. We have established a hypothesis that a diet high in soy consumption is related to a low incidence of breast cancer. Fatty acid synthase (FAS) is a multi-protein enzyme responsible for de novo biosynthesis of fatty acids. Recent studies have demonstrated that high levels of FAS occurs in a subset of human cancers, such as breast cancer, ovarian cancer, and prostate cancer. High level of FAS are associated with a poor prognosis. Sterol regulatory element binding proteins (SREBPs) are a family of transcription factors that regulate genes involved in lipid metabolism, including FAS. Recent studies show that expression of SREBP1c is correlates with FAS expression. The aim of this study is to investigate the effect of genistein on the expression of FAS in breast cancer cells. METHODS: We performed immunofluorescent staining to examine the expression of FAS under different concentration of genistein. RT-PCR was also performed to investigate the mRNA expression of FAS and SREBP1c in different conditioned breast cancer cells treated with different concentration of FAS inhibitor and genistein. RESULTS: By immunofluorescent staining, the FAS expression after treatment with the FAS inhibitor, C75, decreased at a micron10 M concentration. However the expression of FAS decreased at all concentrations of genistein (0.5, 1, 5, 10 micronM). The mRNA levels of FAS and SREBP1c after treatment with C75 decreased constantly according to time and concentration. However the effect was noted only after 12 hr. The mRNA level of FAS and SREBP1c following treatment with genistein decreased at only a 10 micronM concentration (p<0.005). CONCLUSION: Genistein may down regulate FAS expression in breast cancer cells through modulation of SREBP-1c. This finding may account for the relatively low incidence of breast cancer in Asians who consume a large amount of soy in their diet.
