BACKGROUND: To find out characteristics and classification of toxic agents by clinical analysis of pediatric poisoning and to determine the clinical availability of grading by using MSPC score. METHOD: Subjects were patients under 15 years exposed to toxic agents, who visited Ajou university hospital emergency center from June, 1994 to October, 1997. The study was performed retrospectively. RESULTS: The subjects were 126 cases and male to female sex ratio was 1.2:1. Mean age was 29+/-30 months old. The most common route of exposure was ingestion, following contact, inhalation and bite. The most common reason was mistake by the patient, following mistake by caregiver, suicide attempt and accident. The MSPC score distribution of symptomatic patient was as follows; 1 point: 26 cases(63.4%), 2 point: 12 cases(29.2%), 3 point: 1 case(2.4%), 4 point: 2 cases(4.8%). The classification of exposed poison was as follows; therapeutic drugs: 29 cases(23.0%), non-therapeutic drugs: 97 cases(73.0%). The most common exposed poison was household products: 23 patients(18.3%) were admitted to hospital. CONCLUSION: There was statistically significant difference in the classification of poison, MSPC score, treatment modality at hospital, first follow up period after discharge between admitted group and non-admitted group. There was statistically significant difference in the reason of exposure, route of exposure, MSPC score, admission period according to patient's age. severity grading according to MSPC score is regarded as an available method to determine the modality of management.

Soft tissue reconstruction of the hand remains a challenge for the hand surgeon, who must choose whether to use a local flap, a distant flap or a free flap. Local flaps, derived from tissue immediately adjacent to the primary defect, are the first choice. But there is a shortage of skin in the hand and there are regions of the hand that should not be used as donor sites since cover of the resultant secondary defect with a skin graft would be inappropriate. We used island flaps for the small soft tissue defects in the hand which were difficult to cover with a conventional skin graft or local flap. The results were as follows; 1. The causes of the soft tissue defects were traumatic amputation in 4 cases, camptodactyly in 4 cases, replantation in 3 cases, infection in 3 cases and tumor in 1 case. 2. The sites of the soft tissue defects were thumb tip in 6 cases, fifth finger PIP joint volar aspect in 3 cases, index tip in 2 cases, thumb volar and dorsal surface in 2 cases, third and fourth MP joint dorsal surface in 1 case, fourth finger PIP joint volar aspect in 1 case and first interdigital web space in 1 case. 3. The donor flaps were fourth finger neurovascular island flap in 8 cases, reverse dorsal matacarpal flap in 5 cases and first dorsal metacarpal artery flap in 4 cases. 4. The sizes of the flap were from 1. 0×1. 5cm to 2.0×4.0cm and and average of 1.5×2.0cm. 5. The flaps were survive completely with a touch sensat,ion except 2 cases which were covered by reverse 5th dorsal metacarpal flap.

Pain management is an important part of dental practice, and dentists frequently prescribe analgesics to improve clinical outcomes. Dentists should be aware of the pharmacological characteristics of the analgesics commonly used in dentistry and should choose appropriate analgesics to treat and prevent pain associated with inflammation or surgery. In this article, we review the potential benefits and risks of the analgesics frequently used in dental practice and provide a stepwise approach for pain management.

The authors analysed statically 420 Cases of the ocular trauma among 35,460 patients who visited to the emergency department, from Jul. 1995 to Jun. 1996. Ocular trauma is one of the commonest causes of eye diseases and blindness, but its patterns and incidences are variable according to the environment. A large number of patients can be readily treated in the emergency department. Prevention is, of course, the best management, but when an ocular injury occurs, proper emergency treatment can often prevent permanent damage.

In urology technologies and surgical practices are constantly evolving and virtual reality (VR) simulation has become a significant supplement to existing urology methods in the training curricula of urologists. However, new developments in urology also require training and simulation for a wider application. In order to achieve this VR and simulation could play a central role. The purpose of this article is a review of the principal applications for VR and simulation in the field of urology education and to demonstrate the potential for the propagation of new progressive treatments. Two different cases are presented as examples: exposure therapy for paruresis and virtual cystoscopy for diagnosis and surgery of bladder cancer. The article uses research and publications listed in openly accessible directories and is organized into 3 sections: The first section covers features of VR and simulation technologies. The second one presents confirmed applications of current technologies in urology education and showcases example future applications in the domain of bladder treatment and surgery. The final section discusses the potential of the technology to improve health care quality.

To further define the prognostic factors associated with long term survival of hepatocellular carcinoma, we retrospectively studied 371 patients with pathologically diagnosed hepatocellular carcinoma who underwent curative hepatic resection between 1991 and 1995. We included the 16 patients who underwent noncurative hepatic resection in calculating overall survival. The male to female ratio was 5.1 to 1 and their average age was 52.5 years. About 20 variables were subject to univariate and multivariate analysis and their survivals were calculated using the Kaplan-Meier method. 55.6% of (220 of 396) patients had liver cirrhosis and 73.2% of (290 of 396) patients were positive in HBsAg. Operative mortality and inhospital death rate were 1.5% and 0.8%, each and postoperative morbidity rate was 22.5%. The cumulative 1, 3 and 5 year survival rates including noncurative resected cases were 85.9%, 67.2% and 54.8%, respectively. The cumulative 1, 3 and 5 year survival rates of 371 curative resected cases were 87.3%, 68.7% and 56.4%, respectively. Disease free 1, 3, 5 year survival rates of 371 curative resected cases were 74.8%, 48.2% and 40.8%, respectively. The factors such as alpha- fetoprotein, Child's classification, prothrombin time, extent of liver resection, and number of tumor were statistically significant factors associated with cumulative survival.(p<0.05) And alpha-fetoprotein, total necrosis after TACE, viral hepatitis, and invasion of portal vein were significant factors associated with cumulative disease free survival. Only alpha-fetoprotein was associated significantly with cumulative survival and cumulative disease free survival. Length to the resection margin was not significantly associated with survival.

In upcoming fourth industrial revolution era, it is inevitable to address smart healthcare as not only scientist but also clinician. We have the task to plan and realize this through human imagination, creativity, and applicability for the clarification of the direction of the development and utilization of this technology. One thing that is clear is that it is important to understand what information is needed, how to interpret it, what will be the outcomes, and how to respond in artificial intelligence and Internet of Things era. Therefore, we would like to briefly discuss the characteristics of smart healthcare, and, suggest one approach that is easily applicable in the current situation.

Vibrio cholerae non-O1/O139 strains are the organisms that are biochemically indistinguishable from V. cholerae but do not agglutinate in Vibrio cholerae O1 and O139 antisera. V. cholerae non-O1/O139 strains are associated with gastroenteritis and extraintestinal infections such as bacteremia, peritonitis and wound infections. Gastroenteritis by V. cholerae non-O1/O139 is uncommon in Korea. We isolated V. cholerae non-O1/O139 from a stool specimen of a one year-old female with diarrhea and high fever.
