A case of xanthogranulomatous oophoritis is presented in a patient who had a 3-month history of intrapelvic mass protruding into the vagina. The sonographic findings are a well defined mass shadowing lower echogenicity than the echo of the uterus at the posteosuperior aspect of the uterus. The CT findings are an enhancing solid mass with central necrosis containing a multiseptated cystic component.

Mycelium of Hericium erinaceum isolate KU-1 was cultured in liquid medium (HL medium) and solid medium (Ko medium) at pH 4.0 in 28degrees C. 1.0% glucose or fructose was the most favorable carbon source, and 0.2% amonium acetate or NaNO3 was an exellent nitrogen source for mycelial growth as well as production of antimicrobial substances. The mixture of saw dust 70% with rice bran 30% (SR medium) was the substrate for formation of sporophores. The active substrates in extracts from mycelium, culture filtrate and fruiting body were separated by TLC. The solvent for TLC was EtOAc: Chloroform: MeOH (10 : 5 : 10). Phenol-like substances appeared at Rf 0.5~0.9, and fatty acid-like substances appeared at Rf 0.1~0.2. The purified materials from the extracts showed antimicrobial effects to Escherichia coli, Bacillus subtilis, Staphylococcus aureus, Aspergillus niger, Candida albicans and Microsporum gypseum. The S. aureus was the most inhibited. Minimal inhibitory concentration (MIC) of purified white powder and the Hercenone derivatives against S. aureus were 5.65microg/ml and 1.85microg/ml, respectively.

Although the ultlrasonography has been regarded as a main procedure in the diagnosis of bile duct andgallbladder diseases, a few reports concerning the ultrasonographic findings of biliary ascariasis appeared in theliterature. Seven cases of real-time ultrasonographic diagnosis of biliary ascariasis were made in our hospitalduring last 15 months. In six, the diagnosis was confirmed by surgery or radiographic examination. The resultswere as follows; 1. The characteristic long, thick, highly reflective echo without distal acoustic shadowing inthe extra and/or in tra-hepatic ducts were seen in all six proven cases. 2. The echogenic, nonshadowing images ofthe worms were seen as single stripe in five cases(containing a central longitudinal, anechoic tube, suggestingits digestive tract in three cases ) or multiple stripes in one case. But so-called coiled appearance or amorphousfragments were not seen in our cases. 3. Associated findings were as follows; mild to moderate dilatation of theextrahepatic duct in all six duct in 1 case, intrahepatic stone in 1 case, contracted gallbladder containingsingle stone in 1 case and evidence of cholecystitis in 4 cases. 4. One false positive diagnosis of ascariasis inthe gallbladder is considered due to reverberation artefact. No false negative was seen.

Although the ultrasonography has been regarded as a important procedure in the diagnosis of intraabdominalabscess, there were relatively few papers concerning the ultrasonographic findings of periappendiceal abscess.Nineteen cases of surgically proven periappendiceal abscess caused by perforated appendicitis were studied byultrasonography at the Kyung Hee University Hospital during last 34 months. The results were as follows; 1.Diagnostic accuracy of the real-time ultrasonography was 94.7%(18/19). There were only one false positive and onefalse negative. 2. The location of abscesses were ; periappendiceal 68.4%(13/19), pelvic 21.0%(4/19), subhepatic5.3%(1/19) and subphrenic 5.3%(1/19) in order of frequency. 3. Variable echo-patterns of abscesses wereencountered. But irregular, thick walled, posteriorly reinforcing, echo-free or mixed echo-patterns were mostcommon.

NAG activity has been measured in the urine of hypertension, diabetes mellitus and renal disease subjects. Results have shown significantly higher levels of Urinary NAG in hypertension, diaetes and renal disease subjects compared to normal control Subjects group(P<0.001). Urinary NAG measurement is simple and accurate and it provides a valuable information in the early detection of renal dysfunction in hypertension and diabetes subjects and also in the follow up of these patients.

PURPOSE: After successful launches of a 120 W high-power system for photoselective vaporization of the prostate (HPS-PVP), several studies in the United States and Europe have reported good short-term data. Here we report the initial efficacy and side effects of the 120 W HPS-PVP in Korea. MATERIALS AND METHODS: Between January 2008 and January 2009, we performed a retrospective clinical analysis of 133 patients treated by HPS-PVP. RESULTS: The mean age at surgery was 68.4+/-8.0 years. The mean prostate size was 44.2+/-22.6 ml. The mean operation time was 58.9+/-33.5 minutes, and the mean total applied energy was 103,108+/-74,362 J. The mean duration of catheterization was 21.5+/-10.8 hours. The blood loss was minimal, and there were no transfusions. The baseline mean peak urinary flow rate (Qmax) was 10.4+/-5.0 ml/s, mean postvoid residual volume (PVR) was 77+/-91.3 ml, the mean International Prostate Symptom Score (IPSS) was 20.7+/-9.0, and the mean quality of life (QoL) score was 4.2+/-1.3. At 6 months, Qmax was 17.5+/-9.9 ml/sec, PVR was 49.0+/-56.0 ml, the IPSS was 8.0+/-9.0, and the QoL score was 1.6+/-1.5. During the first postoperative month, irritative urinary symptoms were reported in 18 cases, urge incontinence in 7, mild hematuria in 5, urinary tract infection in 2, and temporary recatheterization in 13. CONCLUSIONS: The new 120 W HPS-PVP showed good short-term safety and efficacy for the treatment of Korean patients with benign prostatic hyperplasia.

PURPOSE: To report the change of pupil sizes according to age and illuminance in the normal Korean population. METHODS: Normal Koreans outpatients who never had a history of ophthalmic disease were examined. The patients consisted of 320 eyes of 160 patients, which were classified into 8 age decades (teenage to 80's) with 40 eyes in each age group. The vertical and horizontal pupil size and area under 4 different illuminances (3,500, 1,200, 500, 5 lux) were measured using the Colvard pupillometer(R) (OASIS Medical, Glendora, CA, USA). RESULTS: The pupil size was significantly decreased as the age increased under each illuminance. The pupil area measured after dark adaptation was 47.30 mm2 in the teenage group, 43.32 mm2 in the 20's group, 41.94 mm2 in the 30's group, 40.98 mm2 in the 40's group, 40.61 mm2 in the 50's group, 38.60 mm2 in the 60's group, 37.78 mm2 in the 70's group and 35.45 mm2 in the 80's group. The decrease in pupil area was statistically significant. CONCLUSIONS: In the normal Korean population, a significant decrease in pupil size and area was observed with aging. The present study results provide good basic data for cataract and presbyopia refractive surgery.

Clonorchiasis is known to be closely related with the development of recurrent pyogenic cholangitis and carcinoma of the bile ducts. In order to ascertain the cholangiographic signs for recurrent pyogenic cholangitis or carcinoma of the bile ducts arising in patients with clonorchiasis. we reviewed cholangiograms in 42 patients with proven clonorchiasis. The population consisted of 29 patients with clonorchiasis alone, six patients with clonorchiasis and recurrent pyogenic cholangitis, and seven patients with clonorchiasis and carcinoma of the bile ducts. Cholangiographic abnormalities in 29 patients with clonorchiasis alone, six patients with clonorchiasis and recurrent pyogenic cholangitis, and seven patients with clonorchiasis and carcinoma of the bile ducts. Cholangiographic abnormalities in 29 patients with clonorchiasis alone were intrahepatic multiple, oval, or elliptic filling defects measuring 2-10 mm in size, representing adult flukes (n=24). The peripheral bile duct were obstructed (n=18), and the margins were ragged (n=20) and hazy (n=12) the intrahepatic bile ducts were dilated diffusely (n=27), and the dilated peripheral small tributaries gave the impression of "too many ducts appearance" (n=7) and dilatation was mid (n=17) In six patients with clonorchiasis and recurrent pyogenic cholangitis, there were filling defects of stones, and the extrahepatic ducts and larger intrahepatic ducts were predominantly dilated. In seven patients with clonorchiasis and cholangiocarcinoma all the biliary tree proximal to the tumor was markedly and diffusely dilated In the latter two groups, filling defects of flukes and associated findings were less prominent, but there was disproportionately severe dilatation of too many intrahepatic ducts. In patients with recurrent pyogenic cholangitis or cholangiocarcinoma, clonorchiasis should be considered as a underlying cause when cholangiogram shows "disproportionately" severe dilatation of too many intrahepatic ducts. intrahepatic ducts.

Objective: This study examined the efficacy of artificial intelligence (AI) algorithm-based diagnostic assistant solutions in the interpretation of brain computed tomography (CT) by emergency medicine (EM) residents. Methods: This study included 350 patients who visited a local emergency medical center over 5 months and underwent brain CT scans. EM residents initially interpreted the patients’ scans. A second interpretation was performed using an AI algorithm-based solution. The initial and second interpretations were compared with that of a radiology physician. Results: The first interpretation by EM residents showed agreement in 318 cases (90.9%), while the second, assisted by an AI algorithm-based solution, showed agreement in 308 cases (88.0%). The first interpretation had an accuracy, sensitivity, and specificity of 93.1%, 43.9%, and 99.7%, respectively, and the second had an accuracy, sensitivity, and specificity of 92.0%, 39.0%, and 99.0%, respectively (P<0.001). Most of the discrepancies observed in the first and second interpretations were classified as Grade 1. Conclusion The interpretations assisted by the AI algorithm-based solution resulted in lower accuracy and higher discrepancy rates than independent interpretations by EM residents. The AI algorithm-based solution provided efficacy in accurate interpretation depending on the cases. Further study will be needed to address the weaknesses of the function and utility of AI.
