Objective: This study aims to evaluate the effect of treatment for great saphenous vein incompetence with a fourth-generation 1940 nm laser with radial fiber and catheter directed foam sclerotherapy (CDFS) without a tumescent simultaneously. The procedure was termed laser assisted sclerotherapy (LAST). It is a kind of thermochemical ablation. Methods: From January 1 to June 30, 2023, 86 GSV cases from 50 patients who underwent LAST at Cheongmac hospital were enrolled in this retrospective study. Endogenous laser ablation (EVLA) was performed in the order of accessary vein, tributaries and truncal vein and then followed by CDFS which was performed with a 3% sodium tetradecyl sulfate (STS) mixed with CO 2 gas at a ratio of 1:4. The degree of pain was measured after procedure at 2 hours after the procedure. Follow-up was conducted at 1 week, 1 month, and 6 months. Results: Three of the 86 GSV observed for >6 months showed mild reflux. According to size and number of ablated vessels, various energy level was needed. Three percent STS was used 4.5±0.4 cc and operation time per GSV was about 8±2 minutes. The VAS score was 2.5±0.6 at 2 hours after surgery. The closure rate was 100% at 6 months. Symptoms improved after 6 months in all patients (6.2±1.2 to 0.9±0.2). Conclusion LAST showed a good closure rate in the early midterm follow up period. Ablation was possible with less energy compared with EVLA and the pain index was lower at the second hour after procedure.

Shiitake mushrooms (Lentinula edodes) containing beta-glucans may be beneficial for human health; they have been used in the treatment of cancer, hypertension, and high cholesterol levels. The objective of this study was to determine the beta-glucan content in different sections of the fruiting bodies and mycelia of ten shiitake mushroom cultivars. The measured beta-glucan content ranged from 20.06 +/- 1.76% to 44.21 +/- 0.13% in the pileus sections, and from 29.74 +/- 1.40% to 56.47 +/- 4.72% in the stipe sections. The results of this study indicate that the variance in beta-glucan content dependent on the shiitake cultivar, and that the beta-glucan content is higher in the stipe than in the pileus.

Rabbit hemorrhagic disease is a highly acute and fatal viral disease caused by rabbit hemorrhagic disease virus (RHDV). Since first outbreak in Korea 1987, RHDV has been continually affected in the country, but the pattern of outbreak seem to be changed. In this study, to understand the pathogenesis of the new RHDVa serotype, we therefore carried out to inoculate RHDVa to rabbits, and to examine the sequential histopathologic changes and viral distribution. Macroscopically, various sized dark red or white spots or appearance were observed in the liver, lung, kidney uterus and ureter. In euhanized rabbits, significant pathologic findings such as infiltration of heterophils and mononuclear cells were observed at 24 hours after inoculation (HAI), and these were sequentially extended periportal to centrilobular area. However, in dead rabbits, severe hepatic degeneration and/or necrosis with relatively weak inflammatory responses were observed. RHDV antigens began to detect in liver, spleen, and lung from 12 HAI by PCR. Immunohistochemically, RHDV positive cells were seen in only liver from 24 HAI, and the degree of immunogen reactivity was stronger in dead rabbits than in euthanized ones. In conclusion, RHDVa caused the subacute or chronic infection accompanying low mortality and moderate to severe inflammatory reaction in rabbits, suggesting the possibility that RHD could become endemic.

PURPOSE: It is well known that serum S-100 beta protein levels increased in adults after brain injury. However, there is no definite clinical data in children with isolated minor head trauma. The present study was conducted to validate S-100 beta protein levels as a screening test for brain damage in children with minor head trauma. METHODS: Serum S-100 beta protein levels were measured in 48 pediatric patients with minor head trauma. All patients had brain computed tomography (CT) scan to confirm brain injury. Data were analyzed using a contingency table and a receiver operating characteristic (ROC) curve to determine the diagnostic value of S-100 beta protein levels. RESULTS: Twelve (25%) patients had abnormal brain CT findings. Using a concentration cutoff value of 0.12 ug/L, patients with abnormal brain CT findings were identified by S-100 beta protein levels measurement with a sensitivity level of 100% and a specificity 38.9%. The area under the ROC curve for S-100 beta protein levels was 0.758 (95% CI, 0.606- 0.910). The number of high risk factors were 2.35+/-1.23 in the positive group and 1.53+/-0.76 in the negative group (p=0.011). CONCLUSION: Serum S-100 beta protein levels in children with minor head trauma were similar to those of adults. Our study supports the contention that rapid assessment of serum S-100 beta protein levels may reduce the use of brain CT in children with minor head trauma.

Primary small intestinal lymphoma is relatively uncommon. Small bowel tumors are difficult to diagnose, because they are usually asymptomatic in the initial phase, and they are not easily detected by traditional methods of investigating the small intestine. This case shows a successfully detected and treated gastrointestinal bleeding from rare ileal mucosa-associated lymphoid tissue lymphoma, using double balloon endoscopy.

Nephrotic syndrome is associated with a hypercoagulable state, which results in thromboembolism as one of its main complications. Various pathogenetic factors that cause the hypercoagulable state in nephrotic syndrome have been recognized. We report on a 19-year-old female with a minimal-change disease who developed pulmonary thromboembolism combined with intracardiac thrombus while on tapering steroid. Our patient showed hypoalbuminemia with an episode of shock, and was successfully treated with thrombolysis and anticoagulation therapy.

In this study, we designed to confirm the dietary effect of anti-obesity of fermented soybean curd residue (FSCR; SCR-Meju; Biji-meju) by A. oryzae, which is well known as a Korean traditional meju microbe. We observed that body weight gain, serum and hepatic lipid profile, as well as the activity of ROS generating enzyme and ROS scavenging enzyme in high-fat diet induced obese mice fed experimental diet (SCR and SCR-meju). Body weight gain and epididymal fat weight of HC (high-fat diet control) was markedly higher than that of NC (Normal control). Conversely, body weight gain and epididymal fat weight of the SCR (Biji) and SCR-meju (Biji-meju) group was significantly lower than that of HC; these of the SCR-meju group was lower than that of the SCR group. Furthermore, serum TG and total-cholesterol and LDL-cholesterol contents of SCR and SCR-meju groups were lower than that of HC, and HDL-cholesterol level of the SCR-meju group was significantly higher than that of HC. In conclusion, although precise mechanisms of the antiobese effects of SCR-meju in this study are unknown, the present study provides an experimental evidence that SCR-meju may prevent obesity and obesity related metabolic syndromes, such as hyperlipidemia, hypertension and diabetes, and liver disease by high-fat diet. Nevertheless, further study in this filed will be needed.
