Fibromatosis can occur at various sites, but intracranial fibromatosis is exceptionally rare. Here, we report a case of intracranial fibromatosis arising in the suprasellar area of a 52-year-old woman who had undergone a surgery at that site. A computed tomography scan revealed a heavily calcified, highly enhancing, poorly demarcated mass in the left sellar area that extended into the left suprasellar, parasellar areas, and orbital apex and completely encased the left distal inferior cerebral artery. Histologic and immunohistochemical features were compatible with those of fibromatosis, although the cellularity was focally higher than usual. The etiology of extra-abdominal fibromatosis is unknown, but physical injuries such as trauma and irradiation have been reported to be associated with its occurrence. Although fibromatosis is rare in the intracranial area, it should be considered as a differential diagnosis when an intracranial mass occurs at a previously injured site.

The purpose of this study was to determine the optimal recipe of rice cookies with two different amounts of Stevia rebaudiana leaf and grape seed oil, using a central composite design (CCD). In addition, mixing conditions of rice cookies were optimized by sensory evaluation and mechanical and physicochemical analysis using response surface methodology (RSM). RSM was used to obtain 10 experimental points (including two replicates of Stevia rebaudiana leaf and Grape seed oil), and the formulation of Stevia rebaudiana leaf added rice cookies was optimized using rheology. The results of mechanical and physicochemical analysis showed significant values for lightness, redness, yellowness, hardness, spread factor, loss rate, leavening rate, sweetness, moisture, pH, and density (P<0.001), results of the sensory evaluation showed significant values for color, flavor, taste, texture, appearance, and overall quality (P<0.05). As a results, optimal sensory ratio was found to be 1.98 g of Stevia rebaudiana leaf and 37.94 g of Grape seed oil.

4.Anti-Inflammatory Effects of Fermented Products with Avena sativa on RAW264.7and HT-29 Cells via Inhibition of Inflammatory Mediators
Natural Product Sciences 2020;26(3):244-251
This study investigated therapeutic candidates with anti-inflammatory potential among traditional dietary ingredients targeting inflammatory bowel disease (IBD). Both Avena sativa and traditional fermented products, such as Korean soy paste, are popular health foods. We investigated the anti-inflammatory effects of soy paste combined with A. sativa (KDA), compared with soy paste without A. sativa (KD) by evaluating the expression of pro-inflammatory cytokines in lipopolysaccharide-stimulated RAW264.7 mouse macrophages and HT-29 human colon epithelial cells. KDA significantly inhibited the production of nitric oxide (NO) and downregulated the pro-inflammatory cytokines, such as interleukin (IL)-1β, IL-6, and tumor necrosis factor-α in lipopolysaccharide (LPS)-induced RAW264.7 cells. In another in vitro experiment involving LPS-stimulated HT-29 cells, KDA suppressed the levels of IL-8, which is the chemokine elevated in IBD. In addition, KDA exhibited anti-oxidative properties, such as 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH) and 2,2'-azino-bis(3-ethylbenz-thiazoline-6-sulfonic acid) (ABTS) radical scavenging activity. Our findings revealed that A. sativa combined with soy paste exhibits a synergistic anti-inflammatory and anti-oxidant effect following fermentation.These results suggest that KDA may be used as a potential anti-inflammatory therapy against IBD.

BACKGROUND: Biodegradable microneedle technology is a recently developed method to deliver medical and pharmaceutical medications into the skin, and is expected to yield better treatment results than topical application methods. OBJECTIVE: To evaluate the efficacy of hyaluronic acid (HA)-based microneedle patches and epidermal growth factor (EGF)-containing microneedle patches on periorbital wrinkle improvement. METHODS: A 20-week randomized, double-blind study was performed. Twenty-five Korean patients with periorbital wrinkles and a wrinkle severity rating scale (WSRS) score above 2 were enrolled into the study. The patients completed the study using the two different types of patches on each side of the designated periorbital wrinkles area every other day for 8 weeks. Patients were requested for an additional 12-week follow up. Wrinkle improvements were assessed by WSRS score, subjective patient satisfaction score, and imaging analysis using the visiometer, corneometer, cutometer, and mexameter, respectively (Courage&Khazaka, Cologne, Germany). RESULTS: Both the HA-based microneedle patch and EGF-containing HA-based microneedle patch had positive effects on WSRS score, patient satisfaction levels, and corneometer result with statistically significant differences. No significant side effects were noticed. CONCLUSION: With respect to efficacy, no statistical difference between the two groups were noted, indicating that the anti-wrinkle effects of the microneedle patch may solely be due to the HA rather than the EGF.

Ocular setariases of cattle were reported but those of equine hosts have never been reported in the Republic of Korea (Korea). We found motile worms in the aqueous humor of 15 horses (Equus spp.) from 12 localities in southern parts of Korea between January 2004 and November 2017. After the affected animals were properly restrained under sedation and local anesthesia, 10 ml disposable syringe with a 16-gauge needle was inserted into the anterior chamber of the affected eye to successfully remove the parasites. The male worm that was found in 7 of the cases showed a pair of lateral appendages near the posterior terminal end of the body. The papillar arrangement was 3 pairs of precloacal, a pair of adcloacal, and 3 pairs of postcloacal papillae, plus a central papilla just in front of the cloaca. The female worms found in the eyes of 8 horses were characterized by the tapering posterior terminal end of the body with a smooth knob. Worms were all identified as Setaria digitata (von Linstow, 1906) by the morphologic characteristics using light and electron microscopic observations. This is the first blindness cases of 15 horses infected with S. digitata (Nematoda: Filarioidea) in Korea.

Atherosclerotic renal artery stenosis (RAS) usually involves the ostium and the proximal one-third of the renal artery main branch. Percutaneous renal artery angioplasty with stent placement is a well recognized treatment for atherosclerotic RAS. Occasionally, atherosclerotic RAS involves renal artery bifurcations. However, stent implantation in atherosclerotic RAS involving bifurcation is not only troublesome, but also challenging because of side branch occlusion and in-stent restenosis (ISR). In the present report, we describe the use of drug-eluting stents (DES) with provisional T-stenting technique for the treatment of renal artery bifurcation lesion. Follow-up angiogram showed no significant ISR 18 months after the procedure. In the treatment of renal bifurcation lesions, a two-stent strategy using DES could be a viable option in selected patients.

OBJECTIVES:
We examined the associations of socioeconomic factors, health behaviors, and comorbidities with early-onset lung cancer.
METHODS:
The study included 6,794,287 individuals aged 20-39 years who participated in a Korean national health check-up program from 2009 to 2012. During the follow-up period, 4,684 participants developed lung cancer. Multivariable Cox regression analysis was used to estimate the independent associations of potential risk factors with incident lung cancer.
RESULTS:
Older age (multivariable hazard ratio [mHR], 1.13; 95% confidence interval [CI], 1.12 to 1.14) and female sex (mHR, 1.62; 95% CI, 1.49 to 1.75) were associated with increased lung cancer risk. Current smoking was also associated with elevated risk (<10 pack-years: mHR, 1.12; 95% CI, 1.01 to 1.24; ≥10 pack-years: mHR, 1.30; 95% CI, 1.18 to 1.45), but past smoking was not. Although mild alcohol consumption (<10 g/day) was associated with lower lung cancer risk (mHR, 0.92; 95% CI, 0.86 to 0.99), heavier alcohol consumption (≥10 g/day) was not. Higher income (highest vs. lowest quartile: mHR, 0.86; 95% CI, 0.78 to 0.94), physical activity for at least 1,500 metabolic equivalent of task-min/wk (vs. non-exercisers: mHR, 0.83; 95% CI, 0.69 to 0.99) and obesity (vs. normal weight: mHR, 0.89; 95% CI, 0.83 to 0.96) were associated with lower lung cancer risk, whereas metabolic syndrome was associated with increased risk (mHR, 1.13; 95% CI, 1.03 to 1.24).
CONCLUSIONS
In young adults, age, female sex, smoking, and metabolic syndrome were risk factors for early-onset lung cancer, while high income, physical activity, and obesity displayed protective effects.

BACKGROUND/AIMS: Gastric pathology and Helicobacter pylori (H. pylori) infection among Asian patients with Crohn's disease (CD) are still unclear. We evaluated gastric histologic features and frequency of H. pylori infection in Korean patients with CD. METHODS: Among 492 patients with CD receiving upper gastrointestinal (GI) endoscopic evaluation in 19 Korean hospitals, we evaluated the endoscopic findings and gastric histopathologic features of 47 patients for our study. Histopathologic classification was performed using gastric biopsy tissues, and H. pylori infection was determined using the rapid urease test and histology. RESULTS: There were 36 men (76.6%), and the median age of patients at the time of upper GI endoscopy was 23.8 years (range, 14.2-60.5). For CD phenotype, ileocolonic disease was observed in 38 patients (80.9%), and non-stricturing, non-penetrating disease in 31 patients (66.0%). Twenty-eight patients (59.6%) complained of upper GI symptoms. Erosive gastritis was the most common gross gastric feature (66.0%). Histopathologically, H. pylori-negative chronic active gastritis (38.3%) was the most frequent finding. H. pylori testing was positive in 11 patients (23.4%), and gastric noncaseating granulomata were detected in 4 patients (8.5%). Gastric noncaseating granuloma showed a statistically significant association with perianal abscess/fistula (P=0.0496). CONCLUSIONS: H. pylori-negative chronic active gastritis appears to be frequent among Korean patients with CD. The frequency of H. pylori infection was comparable with previous studies. An association with perianal complications suggests a prognostic value for gastric noncaseating granuloma in patients with CD.
