Accurate analysis of urinary calculi is fundamental for study of the etiology of stone formation and essential for treatment of urinary stone and its prevention. A total of 600 patients underwent treatments with ESWL for urinary tract calculi between May, 1987 and June, 1989. The stone fragments that were passed with 99 patient's urine and 21 stone calculi required surgical removal, were analyzed by infrared spectrometer. The following results were obtained : 1. Mixed calculus (58.3%) in much more than single calculus (41.7% ), The most common type of calculi is calcium oxalate-calcium phosphate (69 cases-57.5% ). The most common type of components is calcium oxalate (105 cases-87.5%). 2. Uric acid stones are found in acid urine, and most of magnesium ammonium phosphate stones are found in alkaline urine. 3. 17 of 120 cases have bacteriuria on culture and most of them are ureasplitting organisms. 4. 21 calculi of failed ESWL were analyzed and the components were calcium oxalate-calcium phosphate in 14, calcium oxalate in 4, magnesium ammonium phosphate in 2, uric acid in 1. 5. The causes of failed ESWL were stone components in 5 cases, impacted stone in 10 cases and poor stone localization in 6 cases.

Infection with Helicobacter pylori (H. pylori) leads to gastritis, but the majority of infected persons are asymptomatic, and it has been recently described that the ability of H. pylori to cause more severe disease is related to the presence of the cytotoxin-associated gene A (cagA). We investigated the prevalence of cagA-bearing strains in a group of H. pylori-positive gastritis, and compared the morphologic differences between cagA-positive and cagA-negative cases on H&E stained slides. Polymerase chain reaction (PCR) assays for detection of H. pylori and cagA of 62 gastric biopsy specimens were performed. All the slides were analyzed by the updated Sydney system. Forty eight (77.4%) were PCR positive for H. pylori and thirty four (54.8%) were positive for cagA. There were no significant differences in numbers of H. pylori, degree of infiltration of mononuclear cells and degree of atrophy between cagA-positive and cagA-negative groups. The rates of neutrophilic infiltration and intestinal metaplasia were significantly higher in cagA-positive group than in cagA-negative group. In conclusion, the detection of H. pylori by PCR method is more sensitive than that of microscopic examination and H. pylori strains possessing cagA are associated with an enhanced induction of severe gastritis.

An intraosseous epidermal cyst is a rare benign cystic lesion. It is thought to result from congenital factors or trauma and can lead to bone destruction because the cyst develops at the soft tissue around the bone. Radiological findings of intraosseous epidermal cysts are a well-defined radiolucent lesion, with cortical expansion. It is important to differentiate an intraosseous epidermal cyst with other disease developed at distal phalanx because its clinical and radiological findings are similar. We report two rare cases of intraosseous epidermal cysts that developed at the distal phalanx.

Embolization of a carotid cavernous fistula(CCF) by means of a detachable balloon is a well-established method for treating CCFs while preserving a patent parent internal carotid artery(ICA). However, failure to embolize the CCF may occur on a few occasions. Herein we describe a stent-assisted Guglielmi detachable coil embolization that completely occludes the fistulous opening rather than fills the cavernous sinus. By applying this technique, we successfully treated a CCF, without compromise of the parent ICA in patients who has failed with balloon technique previously.

Ophthalmic surgery presents challenges for the anesthesiologists, including control of intraocular pressure, prevention and management of the oculocardiac reflex. In addition to understanding ocular anatomy and physiology, the anesthesiologists must have possess technical expertise and knowledge of ophthalmic drug's systemic effects. Patients undergoing ophthalmic surgery have extremes of age and several medical diseases, like as hypertension, diabetes mellitus, coronary heart disease, chronic renal failure, and chronic obstructive lung disease. Anesthesiologist should be knowledgeable about the content as stated above to perform safe and desirable anesthesia for ophthalmic surgery.

Medical managements and prevention of deep vein thrombosis(DVT) continue to be a difficult problem and DVT often result in serious complications, in spite of improvements in early diagnosis of DVT. Various attemps to treat effectivly and to prevent DVT have been tried. We reviewed 82 patients who were admitted to Department of Surgery of Chonnam University Hospital for treatment of DVT from January, 1991 to May, 1997. The results were as follows. 1) There was a wide age distribution from teenage to 8th decade, and peak age distribution was 7th decade(28.0%). Sex distribution of DVT, male to female ratio, was 1 : 1.1. 2) Main chief complaint in patients with DVT was swelling of lower extremities(97.5%), and followed by pain(51.2%). The left side of lower extremities was more frequently affected than that of right side, left to right ratio was 2.2 : 1. 3) Occupations of patients with DVT were variable, fourty patients(48.8%) had no specific occupations. 4) Most frequent predisposing factor of DVT was trauma(12.2%) and followed by malignancy (11.0%) and operation(7.3%). 5) Diagnosis of DVT was made with plethysmography in all cases, and venography(25 cases), radioiodine(RI) venography with lung scan(7 cases). 6) Treatment was done with heparin and oral anticoagulant in most patients for 3 to 12 months. Fogarty thrombectomy was done in 4 cases, but adequate removal of thrombi was failed in 2 cases because the catheter couldn't be advnaced into the site of thrombi. Anticoagulant therapy was done for 2

BACKGROUND/AIMS: Hepatocytes on the hepatic lobule mipate from portal zone to centrilobular mea as the DNA synthesis within it. And also, the xenobiotic reactions reveal characteristic differences associated with zone specific metabolism in the liver acinus. In this study, the zonal distribution of ethylnitrosourea (ENU)-induced hepatic precancerous lesion was stereologically investigated. METHODS: Nine B6C3F1 mices were given I.p. injection of ENU (60 ug/pn body weight) when the pups were 15 days old prior to sacrifices at 8 weeks of life. All the 150 consecutive sections, 3 p m in thickness, were stained with hematoxylin and eosin and identified the basophilic precancerous lesions with 80-165 p m diameter in equatorial plane by the Zeiss microprojector. And then the distances from the center of selected foci to terminal hepatic vein or portal vein branches were estimated under the microscopic fields. As a control group, the same estimations were performed from the random points by the appointments of random digit table. RESULTS: Mean distance between ENU-induced 52 hepatocellular foci and the nearest terminal hepytic vein was 181.15+112.39 p m (Mean+ SD), but that of randomly selected 104 points was 291.73+157.98pm (Mean+5D) (Students t-test, p<0.0005). Substantially, 52.7% of ENU-induced 52 hepatocellular foci were within 300 p m from the terminal hepatic vein, but randomly selected 104 points were only 50.9% (Shapiro Wilk W test, w=0.819857, p=0.048038). Mean distance from ENU-induced 52 foci to portal vein was 398.85+149.98pm (Mean+SD), but that from the randomly selected 104 points was 315.87+145.79 pm (Mean+SD)(Students t-test, p<0.0005). CONCLUSION: Stereologically, ENU-induced mice liver cell foci distribute non-randomly to Zone III, centrilobular zone of mouse hepatic acini where promote invasion toward terminal hepatic veins.

BACKGROUND: This study aimed to present our 5-year experience of extracorporeal cardiopulmonary resuscitation (ECPR) performed by emergency physicians. METHODS: We retrospectively analyzed 58 patients who underwent ECPR between January 2010 and December 2014. The primary parameter analyzed was survival to hospital discharge. The secondary parameters analyzed were neurologic outcome at hospital discharge, cannulation time, and ECPR-related complications. RESULTS: Thirty-one patients (53.4%) were successfully weaned from extracorporeal membrane oxygenation, and 18 (31.0%) survived to hospital discharge. Twelve patients (20.7%) were discharged with good neurologic outcomes. The median cannulation time was 25.0 min (interquartile range 20.0-31.0 min). Nineteen patients (32.8%) had ECPR-related complications, the most frequent being distal limb ischemia. Regarding the initial presentation, 52 patients (83.9%) collapsed due to a cardiac etiology, and acute myocardial infarction (33/62, 53.2%) was the most common cause of cardiac arrest. CONCLUSIONS: The survival to hospital discharge rate for cardiac arrest patients who underwent ECPR conducted by an emergency physician was within the acceptable limits. The cannulation time and complications following ECPR were comparable to those found in previous studies.
