1.Comparison of Multilevel with Single Level Injection during Lumbar Sympathetic Ganglion Block: Efficacy of Sympatholysis and Incidence of Psoas Muscle Injection.
The Korean Journal of Pain 2010;23(2):131-136
BACKGROUND: We prospectively evaluated the incidence and possible factors causing intramuscular injection during lumbar sympathetic ganglion block and compared the multiple needle technique to the single technique to obtain a profound and complete block effect. METHODS: Among 83 patients, 58 patients (group A, n = 27, multiple needle technique and group B, n = 31, single needle technique) were reevaluated for the changes of skin temperature (Ts) and mean segment of longitudinal contrast spread. After injecting the contrast agent, the incidence of psoas muscle injection and the change of Ts was compared between two groups. RESULTS: The incidence of psoas muscle injection was 21.3% (46/216) and it was associated with the level of injection (L2) significantly (chi-square = 14.773, P = 0.001). DT(post) (postblock temperature difference between ipsilateral and contralateral great toe, 4.6 +/- 2.8degrees C, 1.8 +/- 1.6degrees C, P < 0.001 for group A and B) and DT(net) (DT(post) - DT(pre), 3.9 +/- 2.7degrees C, 1.5 +/- 1.5degrees C, P < 0.001 for group A and B) was significantly higher in group A. The mean segment of longitudinal contrast spread was 8.1 +/- 0.9 for group A and 3.2 +/- 1.6 for group B (P < 0.001). CONCLUSIONS: The LSGB at the L2 level showed the lowest incidence of psoas muscle injection of contrast. Multiple needle approach showed more significant increase of DT(net) and DT(post).

PURPOSE: This treatment planning study was undertaken to evaluate the impact of beam angle configuration of intensity-modulated radiotherapy (IMRT) on the dose of the normal liver in hepatocellular carcinoma (HCC). MATERIALS AND METHODS: The computed tomography datasets of 25 patients treated with IMRT for HCC were selected. Two IMRT plans using five beams were made in each patient; beams with equidistance of 72degrees (Plan I), and beams with a 30degrees angle of separation entering the body near the tumor (Plan II). Both plans were generated using the same constraints in each patient. Conformity index (CI), homogeneity index (HI), gamma index, mean dose of the normal liver (Dmean_NL), Dmean_NL difference between the two plans, and percentage normal liver volumes receiving at least 10, 20, and 30 Gy (V10, V20, and V30) were evaluated and compared. RESULTS: Dmean_NL, V10, and V20 were significantly better for Plan II. The Dmean_NL was significantly lower for peripheral (p = 0.001) and central tumors (p = 0.034). Dmean_NL differences between the two plans increased in proportion to gross tumor volume to normal liver volume ratios (p = 0.002). CI, HI, and gamma indices were not significantly different for the two plans. CONCLUSION: The IMRT plan based on beams with narrow separations reduced the irradiated dose of the normal liver, which would allow radiation dose escalation for HCC.

Purpose:
With the 2021 revision of dietary guidelines in Korean emphasizing environmentally sustainable dietary practices, this study attempted to develop an evaluation tool to comprehensively evaluate the degree of practice and compliance with food and nutrient intake, dietary habits, and dietary culture guidelines based on the revised dietary guidelines.
Methods:
The candidate evaluation items were collected by reviewing 934 literature reviews on domestic and foreign dietary evaluations. Fifty-nine candidate items were derived by selecting the items corresponding to dietary guidelines. The content validity ratio (CVR) cutoff point evaluation was conducted with 11 experts to delete 11 items that did not meet the CVR standard. Fifty-five pilot survey candidate items were selected through revision and additional process according to expert opinion. Seventy final candidate items were selected by adding 15 questions for validity verification and reference. A pilot survey was conducted online and offline on 332 adults aged 19–64 in Seoul and the metropolitan area, and exploratory factor analysis was used to verify the construct validity of the evaluation items. Through exploratory factor analysis, the Kaiser–Meyer–Olkin, Bartlett's sphericity test, variance explained, and Cronbach's alpha criteria were confirmed in each process.
Results:
Exploratory factor analyses derived three criteria: food and nutrient intakes (11 items), eating behaviors (9 items), and dietary culture (14 items), consisting of 34 evaluation items.
Conclusion
The present scale was validated and can be used for comprehensive evaluations of the dietary guidelines for Korean adults in a simple way.

Background:
The direct entry of the camera under the epiglottis may provide a better view of the glottis than the indirect lifting of the epiglottis by placing the Macintosh blade tip on the vallecula when using the video laryngoscope. This study aimed to compare the efficiency of two different methods of lifting the epiglottis during the visualization of glottis using video laryngoscopy in the same patient.
Methods:
This prospective study enrolled 60 patients who underwent general anesthesia with tracheal intubation. In each patient, glottic views were obtained by directly (group DE) and indirectly lifting the epiglottis (group IE). These two methods were compared using the modified Cormack and Lehane grade and the percentage of glottis opening (POGO) score as assessment parameters.
Results:
Modified Cormack and Lehane grade showed a significant difference between the groups DE and IE (P = 0.004). The difference in the POGO score between the groups DE and IE was also statistically significant (87.5% and 64.4%, respectively; P < 0.001).
Conclusions
Our results, therefore, revealed that the method of directly lifting epiglottis was better at exposing glottis than the method of indirectly lifting epiglottis using a video laryngoscope.

White strains of Hypsizygus marmoreus are more difficult to cultivate than are brown strains; therefore, new white strain breeding strategies are required. Accordingly, we constructed the genetic map of H. marmoreus. with 1996 SNP markers on 11 linkage groups (LGs) spanning 1380.49 cM. Prior to analysis, 82 backcrossed strains (HM8 lines) were generated by mating between KMCC03106-31 and the progenies of the F1 hybrid (Hami-18 × KMCC03106-93). Using HM8, the first 23 quantitative trait loci (QTLs) of yield-related traits were detected with high limit of detection (LOD) scores (1.98–9.86). The length, thickness, and hardness of the stipe were colocated on LG 1. Especially, length of stipe and thickness of stipe were highly correlated given that the correlation coefficients were negative (−0.39, p value ≤ .01). And a typical biomodal distribution was observed for lightness of the pileus and the lightness of the pileus trait belonged to the LG 8, as did traits of earliness and mycelial growth in potato dextrose agar (PDA) medium. Therefore, results for color traits can be suggested that color is controlled by a multi-gene of one locus. The yield trait was highly negatively correlated with the traits for thickness of the stipe (−0.45, p value ≤ .01). Based on additive effects, the white strain was confirmed as recessive; however, traits of mycelial growth, lightness, and quality were inherited by backcrossed HM8 lines. This new genetic map, finely mapped QTLs, and the strong selection markers could be used in molecular breeding of H. marmoreus.

Pulmonary artery aneurysms (PAAs) are rare, and massive hemoptysis can lead to death if appropriate diagnosis and treatment is not provided. PAAs can be of congenital, acquired, or idiopathic origin, and the clinical symptoms are various. Among all reported cases, one-third of the patients died due to rupture. Optimal treatment or guidelines for PAAs remain uncertain. Herein, we report autopsy findings from a woman with PAA. The patient was taking medication for tuberculosis. On bronchoscopy, a polypoid lesion was found, suspected to be an inflammatory polyp. Biopsy was performed and massive bleeding into the airway occurred. The bleeding could not be controlled by bronchoscopic suction, and cardiac arrest occurred 30 minutes after biopsy; the patient subsequently died. Autopsy revealed a round, calcified PAA in the bronchus of the right middle lobe; the end of the PAA was torn. Hypovolemic signs, including weak postmortem lividity and pallor of the skin and conjunctivae, were observed. Visual inspection and histopathological examination of the right lung revealed tuberculosis and congestion. Cases related PAA are not uncommon, but autopsy cases of death occurring after biopsy of PAA mimicking bronchial polyps are rarely reported.
