즉석섭취편이 식품중 신선편의식품(fresh-cut-vegetable)인 새싹 채소와 샐러드의 수요는 급증하고 있으나 특히 새싹채소의 미생물 품질평가를 위한 자료가 거의 없는 상황이다. 따라서 국내 대형할인마트에서 유통중인 새싹채소 50제품, 샐러드 30제품을 수집하여 총 호기성균, 대장균군, E. coli, Salmonella spp, S. aureus, B. cereus, L. monocytogenes, Cam. jejuni, C. perfringens의 오염연구를 수행하였다. 총 호기성균은 새싹채소에서는 7.95 log CFU/g 검출되었으며 샐러드에서 평균 6.70 log CFU/g검출되어 샐러드 보다 새싹채소에서 약 1 log CFU/g 더 높게 검출되었다. 대장균군은 새싹채소에서 6.69 log CFU/g 검출되었고 샐러드에서 평균 5.42 log CFU/g 검출되었다. E. coli은 새싹채소 50제품 중 16제품(32%)에서 2.38 log CFU/g으로 검출되었고 샐러드 30제품 중 8제품(27%)에서 2.21 log CFU/g으로 검출되었다. B. cereus는 새싹채소 50제품 중 16제품(32%)이 검출되었고 샐러드 30제품 중 16제품(53%)가 검출되었으나 대부분이 3 log CFU/g 이하의 검출율을 보여 주었다. Salmonella, S. aureus, L. monocytogenes, Cam. jejuni, C. perfringens는 검출되지 않았다. 그러므로 분석된 새싹채소와 샐러드에서 B. cereus이외에 다른 식중독 병원성 미생물의 위해 가능성은 크지 않은 것으로 보인다. 그러나 총 세균수가 높게 검출되었고 위생지표세균인 대장균의 검출율이 높아서 이들 식품의 미생물 안전성을 확보하기 위해서 보다 더 철저한 생산유통관리가 요망되며 특별히 새싹채소에 대한 미생물안전성 확보에 대한 노력이 요구된다. Although bacterial outbreaks from ready-to-eat foods have increased, little information is available on microbial quality of sprouts in markets. Fifty sprouts and 30 salads were collected from wholesale markets. Total aerobic count (TAC), coliform, Escherichia coli, and some pathogens were detected. TAC for sprouts was 7.95 log CFU/g and 6.70 for salads, indicating that sprouts were more contaminated by 1 log CFU/g than that of salads. The numbers of coliform were 6.69 log CFU/g for sprouts and 5.42 for salads. E. coli was detected in 16 of 50 sprout samples at 2.38 log CFU/g and eight of 30 salads at 2.21 log CFU/g. Bacillus cereus was detected in 29 of 50 sprout samples and 16 of 30 salads, and the counts were mostly <3 log CFU/g. Salmonella, Staphylococcus aureus, Listeria monocytogenes, Campylobacter jejuni, and Clostridium perfringens were not detected. Therefore, although pathogens may not be a high risk for these foods, the high TAC and E. coli contamination require improved production and distribution methods, particularly for sprouts.

STUDY DESIGN.: A retrospective cohort study. OBJECTIVE.: To evaluate the clinical and radiological efficacies of supplementing minimally invasive lateral lumbar interbody fusion (LLIF) with open posterior spinal fusion (PSF) in adult spinal deformity (ASD). SUMMARY OF BACKGROUND DATA.: Minimally invasive techniques have been increasingly applied for surgery of ASD. Few reports have been published that directly compare LLIF combined with PSF to conventional PSF for ASD. METHODS.: To evaluate the advantages of minimally invasive LLIF for ASD, patients who underwent minimally invasive LLIF followed by open PSF (combined group) were compared with patients who only underwent PSF (only PSF group). The clinical and radiological outcomes for deformity correction and indirect decompression were assessed. The occurrence of proximal junctional kyphosis (PJK) and proximal junctional failure (PJF) were also evaluated. RESULTS.: No significant differences were observed in the clinical outcomes of the Oswestry Disability Index (ODI), visual analog scale, and major complications including reoperations between the groups. No additional advantage was found for coronal deformity correction, but the restoration of lumbar lordosis in the combined group was significantly higher postoperatively (15.3° vs. 8.87°, P = 0.003) and last follow-up (6.69° vs. 1.02°, P = 0.029) compared to that of the only PSF group. In the subgroup analysis for indirect decompression for the combined group, a significant increase of canal area (104 vs. 122 mm) and foraminal height (16.2 vs. 18.5 mm) was noted. The occurrence of PJK or PJF was significantly higher in the combined group than in the only PSF group (P = 0.039). CONCLUSION.: LLIF has advantages of indirect decompression and greater improvements of sagittal correction compared to only posterior surgery. LLIF should be conducted considering the above-mentioned benefits and complications including PJK or PJF in ASD.Level of Evidence: 4
A case of elephantiasis nostras verrucosa on great toe
( Sang-woo Park ),( Sang-kyung Lee ),( Eui-sung Jung ),( Hyun-bin Kwak ),( Su-kyung Park ),( Jin Park ),( Han-uk Kim ),( Seok-kweon Yun ) 대한피부과학회 2019 대한피부과학회 학술발표대회집 Vol.71 No.1
Elephantiasis nostras verrucosa is an uncommon disorder that is characterized by verrucous changes with papillomatosis and hyperkeratosis. The affected skin acquires a mossy or cobblestone-like appearance and discrete fibrous papules or plaques may develop. Recurrent cutaneous infections, tumor obstructions, previous surgeries, radiations, and obesity can lead to chronic lymphatic obstruction and edema. A 63-year-old man presented with non-pitting edema and hyperkeratotic warty plaque in left great toe for 1 month. The patient had been diagnosed with diabetes for 30 years and had a history of diabetic foot and recurrent localized infection on the left great toe for 5 years. He denied history of other trauma, radiation therapy, and travel outside of Korea before. Staphylococcus aureus was identified on the bacterial culture performed with discharge, and fungal culture was negative. The histopathological examination of the biopsy sample revealed hyperkeratosis, papillomatosis, and pseudoepitheliomatous hyperplasia of the epidermis. Diffuse fibrosis and dilated lymphatic channels are observed in the dermis. Periodic acid-Schiff, and acid fast bacilli stains were negative for fungal and mycobacterial organisms. Based on the clinical and histopathological findings, the patient was diagnosed with elephantiasis nostras verrucosa. The patient was treated with topical salicylic acid, and showed little improvement after 3 month.

The purpose of this study was to determine the effects of heat appli˗ cation on the immune activities of the human body. To exam, further˗ more, the immune effect from the healthy volunteer(male:15, female:15) by monitoring changes of immune substances such as various leukocytes[total white blood cell(WBC), eosinophil, neutrophil, basophil, monocyte, and lymphocyte], a comparative study with warm water immersion(40.8±0.3℃) and infrared(250W) was carried out. The plasma analysis showed that the count of white blood cell, eosinophil, and neutrophil were elevated in warm water immersion- or infrared˗ stimulated group compared with control group. However, the count of basophil was decreased in both warm water immersion- and infrared-stimulated group than control group. Therefore, these results suggest that the thermostimulation improved immune activity.

The authors report a case of spinal dural arteriovenous fistula (SDAVF) that is supplied by a lateral sacral artery. A 73-year-old male presented with gait disturbance that had developed 3 years ago. Spinal magnetic resonance imaging suggested a possible SDAVF. Selective spinal angiography including the vertebral arteries and pelvic vessels showed the SDAVF fed by left lateral sacral artery. The patient was subsequently treated with glue embolization. Three days after the embolization procedure, his gait disturbance was much improved.
