BACKGROUND: Triage and transportations are important and life-saving medical task performed at the site of mutiple-casualty incidents(MCIs). We pursued three road traffic accidents victims to find out any problem in triaging and transporting them, and to provide an information for equipping an local disaster planning. METHODS: The medical records of 70 consecutive patients who were transported to five emergency facilities in Kangnung, on three MCIs from 1998 to 2000, were analysed, retrospectively. The intervals and types of transport vehicles were analysed. We compared the prehospital time between severity-based groups, which were graded into 3 groups according to the Triage score(0, 1~8, 9). RESULTS: Among the 70 patients, 33 patients(47.1%), 21 patients(30%), and 16 patients(22.9%) were transported to Level I, Level II, and Level III trauma centers, respectively. The time elapsed from scenes to the Level I trauma center was significantly shorter(p=0.003) than to others, but no differences in the mean Triage score between trauma centers were seen(p>0.05). The 119 rescue services transported 58.6%(41 patients) of victims to emergency facilities, and 58.5%(24 patients) of them was concentrated to Level I. There were no significant differences in the prehospital time between three Triage score groups(p>0.05). CONCLUSION: There was no medical control such as triage and transportation in the cases of three MCIs. In the construction of emergency medical service system(EMSS) preparing MCIs or disasters, we suggest the integration and unification of 119 rescue services and emergency medical information centers for effective medical control. We propose to making a new and simple triage guideline. The prehospital personnel should be educated and disaster drills should be performed under the guideline.

PURPOSE: The prognosis for patients with a Borrmann type IV gastric cancer is extremely poor despite an aggressive surgical approach. We evaluated the clinicopathological features for Borrmann type IV cancers to find treatment strategy. MATERIALS AND METHODS: The 1098 patients with advanced gastric cancer who underwent surgical resection between 1990 and 2001 were analyzed. These patients were divided into two groups: 81 patients with a Borrmann type IV carcinoma, and 1017 patients with all other types of gastric carcinomas. RESULTS: Patients with a Borrmann type IV carcinoma were younger than those with other types, and female was prevalent (p=0.000). Of the patients with a Borrmann type IV gastric carcinoma, 68 patients (84%) were classified as stage III or IV at the initial diagnosis. The histologic type was commonly undifferentiated and serosal infiltration; nodal involvement and lymphatic invasion were more frequent in patients with a Borrmann type IV than in those with other types of cancer. Multivariate analysis confirmed that the extent of lymph node metastasis was a negative prognostic factor for Borrmann type IV gastric carcinomas. The curability for a Borrmann type IV carcinoma was only 53.1%, and peritoneal dissemination rate was 25.9%. The predominant pattern of recurrence for a Borrmann type IV gastric carcinoma was peritoneal dissemination, and it was significantly different with other types (93.1% vs 55.8%, P<0.05). The 5-year survival rate of patients with a Borrmann type IV gastric carcinoma was significantly lower than those of patients with other types of cancer, even though a curative resection had been accomplished (26% vs 63%, p<0.005). The 5-year survival rates of patients with a Borrmann type IV carcinoma following a curative resection were 44.9%, 24%, and 0% for stages II, III and IV, respectively (p<0.05). CONCLUSION: Because the prognosis for patients of a Borrmann type IV gastric cancer is extremely poor despite a curative resection, preoperative and/or intraperitoneal chemotherapy should be considered. And diagnostic laparoscopy and peritoneal cytology may be used to play an important role in accurate staging workup.

BACKGROUND: Production of nitric oxide (NO) by inducible NO synthase (iNOS) has been implicated in the pathology of autoimmune disease. It is unknown whether iNOS expression is increased within testes and whether iNOS and NO have essential roles in the pathogenesis of EAO. METHODS: EAO was induced in guinea pig testes at 17 days after secondary immunization by administration of crude extract (CE) and purified glycoprotein 1 (GP1) from normal guinea pig testes. iNOS gene expression was assessed by RT-PCR and Northern blot analysis in testes. Localization of iNOS and Mac-1 and the indicator of NO-mediated tissue injury, nitrotyrosine, were detected in the testicular lesion by immunohistochemistry. RESULTS: In control testes, inflammation and iNOS gene expression were not detected, whereas, in CE- and GP1-injected testes, inflammation and marked iNOS gene expression were evident at day 17 after secondary immunization. Immunohistochemistry of Mac-1 showed the colocalization with iNOS protein and nitrotyrosyl proteins in intertubules, suggesting that NO produced by infiltrated macrophages may be involved in inflammatory lesions of intertubules. Intraperitoneal administration of aminoguanidine significantly prevented EAO with reduction of inflammation, iNOS expression and nitrotyrosine formation. CONCLUSION: These results suggest that NO production by macrophages may be important in the pathogenesis of CE- and GP1-induced EAO. Furthermore, this study demonstrated the therapeutic potential of iNOS inhibitor in the treatment of inflammatory and autoimmune mediated-diseases.

PURPOSE: Laparoscopic totally extraperitoneal herniorrhaphy (TEP) was developed as an alternative treatment of inguinal hernias to open hernia repair. This study evaluated 92 cases of laparoscopic surgery to determine the effectiveness and safety of laparoscopic TEP. METHODS: Laparoscopic TEP was performed on 92 patients with inguinal hernias from January 2008 to December 2010. Through a retrospective study of these patients, information om TEP repair was collected including the patients' characteristics, operation time, hospital stay, analgesic use and related complications. RESULTS: Laparoscopic herniorrhaphy were performed on a total of 92 patients (85 men and 7 women, age ranging from 16 to 83 years, with a mean of 56 years). The mean operation time for a unilateral inguinal hernia and bilateral inguinal hernia was 58.7 and 84.2 min, respectively. The mean postoperative hospital stay was 4.0 days (range, 2~9 days). Thirty nine patients were discharged without an analgesic injection, whereas 36 patients were injected with analgesic on the day of surgery. Of these 92 procedures, 10 complications were recorded; one granuloma complication, two patients with operation site discomfort, five with urinary retention issues, one patient with a scrotal seroma, and one patient with scrotal edema. CONCLUSION: TEP repairs have minimal morbidity and are more effective with less pain than the open procedure. TEP repair can be considered a favorable procedure for patients who request minimally invasive procedures for inguinal hernia repairs.

This study aimed to evaluate the effectiveness of deep convolutional neural networks (CNNs) for diagnosis of interproximal caries in pediatric intraoral radiographs. A total of 500 intraoral radiographic images of first and second primary molars were used for the study. A CNN model (Resnet 50) was applied for the detection of proximal caries. The diagnostic accuracy, sensitivity, specificity, receiver operating characteristic (ROC) curve, and area under ROC curve (AUC) were calculated on the test dataset. The diagnostic accuracy was 0.84, sensitivity was 0.74, and specificity was 0.94. The trained CNN algorithm achieved AUC of 0.86. The diagnostic CNN model for pediatric intraoral radiographs showed good performance with high accuracy. Deep learning can assist dentists in diagnosis of proximal caries lesions in pediatric intraoral radiographs.

BACKGROUNDS/AIMS: In the treatment of complicated cholecystitis, laparoscopic cholecystectomy (LC) has limited efficacy due to its substantial post-operative complications. In addition, the clinical characteristics of complicated cholecystitis (CC) patients were suspected as advanced age with highly risky comorbidity. Percutaneous transhepatic gall bladder (PTGBD) drainage could be an alternative option for successful LC. Hence, this study evaluated the outcome of PTGBD for CC within and after 5 days. METHODS: The medical records of 109 consecutive CC patients who had undergone an LC between January 2007 and December 2011 were retrospectively reviewed and compared with the medical records of CC patients who had undergone an LC within 72 hours of (group I, n=63) or 5 days after PTGBD (group II, n=40). In addition, group I was divided into group Ia (n=46) and group Ib (n=17), according to the patients' development of open-conversion or post-operative complications. The clinical outcomes of the four groups were analyzed. RESULTS: There was a significantly higher reference to age, the ASA score grading, and predominant comorbidities in group II than in group I. The peri-operative results of group II showed lower blood loss and relatively shorter operating times than those of group I. In the cases of early LC within 72 hours (group Ia vs. group Ib), the difference was statistically insignificant. CONCLUSIONS: The delayed LC after PTGBD for complicated cholecystitis with high clinical risk had better results in this study, although it prolonged the patient's hospital stay.

Recent developments in virtual, augmented, and mixed reality have introduced a considerable number of new devices into the consumer market. This momentum is also affecting the medical and health care sector. Although many of the theoretical and practical foundations of virtual reality (VR) were already researched and experienced in the 1980s, the vastly improved features of displays, sensors, interactivity, and computing power currently available in devices offer a new field of applications to the medical sector and also to urology in particular. The purpose of this review article is to review the extent to which VR technology has already influenced certain aspects of medicine, the applications that are currently in use in urology, and the future development trends that could be expected.

Pulmonary alveolar proteinosis (PAP) is a noninflammatory diffuse lung disease, characterized by a dense accumulation of lipoproteinaceous material within the alveoli, causing hypoxemia, restrictive lung disease, and abnormalities on chest radiograph. The etiology of PAP is uncertain and various forms, including idiopathic and disease secondary to dust or fume exposure. Bronchopulmonary lavage (BPL) is a safe and effective treatment in PAP, and a unique procedure which requires general anesthesia and separation of the lung with a double lumen endobronchial tube. We experienced anesthetic management of BPL for the successful treatment of a 33 years old female patient with PAP.
