OBJECTIVES: Recently, the number of adolescent criminals hospitalized for evaluation or treatment of mental illness is increasing. The aim of this study was to provide basic information for the evaluation and treatment of adolescent misconducts, based on their impulsivity. METHODS: Barrat's impulsivity test was done to 64 adolescent criminals under age of 18 who were admitted to a Juvenile School between Oct. 1, 2003 and June 30, 2004. According to their recognizing impulsivity scores, the upper 30% group (high impulsivity group: HIG) and the lower 30% group (low impulsivity group: LIG) were selected. The two groups were compared on socio-demographic data, crime characteristics, psychiatric diagnoses, Evoked Potential Latency and Amplitude, Cognitron and IQ. RESULTS: 1) The high impulsivity group had lower IQ than the low impulsivity group (p<0.01). 2) No difference was found in the seriousness of committed crimes, number of crimes and the age of first committed crimes. However, the high impulsivity group fended acting alone in committing crimes (p<0.05), and more frequently upeated same crimes (p<0.01). 3) Evoked potential latency was prolonged on FzN100 (p<0.05), CzN100 (p<0.05), PzN100 (p<0.01) and amplitude was increased on FzN100 (p<0.05), CzN100 (p<0.05), PzN100 (p<0.05) in high impulsivity group. 4) High impulsivity group showed lower scores on NOCR (p<0.01), NOCYR (p<0.01), NOCNR (p<0.01) in Cognitron. PzN100 (p<0.05) latency prolongation. CzN100 latency prolongation had positive correlation with PzN100 latency prolongation (p<0.05). 5) While the misconduct was most common problem in both groups, more ADHD diagnosis was identified in the high impulsivity group. The most frequent medical problem in low impulsivity group was with diseases of internal medicine (p<0.01) and anxiety disorders (p<0.01). CONCLUSION: The adolescent criminals with high impulsivity tend to have lower intelligence and commit crimes repeatedly. They are frequently diagnosed to have ADHD. When they are compared to low impulsivity group, big differences are found in prolonged evoked potential latency and increased amplitude on N100. Hence, in the treatment and rehabilitative programs for them, considering these characteristics may be helpful.

PURPOSE: To report a case of a macular hole resulting from accidental exposure to tattoo removal by the Q-Switched Nd:YAG laser, which was treated successfully by vitrectomy and silicone oil infusion. CASE SUMMARY: A 33-year-old man presented with decreased visual acuity after accidental exposure to a Q-Switched Nd:YAG laser. According to fundus examination, vitreous hemorrhage and macular edema were observed. After 21 days, a macular hole had developed which was treated by standard pars plana vitrectomy and gas tamponade. Unfortunately, closure was not obtained on the first attempt. Therefore, a second attempt using silicone oil infusion was performed. Four months after the initial visit, BCVA had increased to 20/50, and anatomical occlusion was achieved. CONCLUSIONS: The authors of the present study experienced an unusual case of macular hole developed from the Q-Switched Nd:YAG laser used to remove a tattoo. A satisfactory visual acuity was achieved after silicone oil infusion despite failure in the first surgery.

Mesenchymal chondrosarcoma is a rare tumor occurring in both bone and soft tissues and exhibits characteristic of a malignant nature. The authors experienced a case of mesenchymal chondrosarcoma occurring in a 23-year-old woman which had invaded the cervical spine. The patient presented with severe both shoulder pain, left upper extremity weakness(Grade IV) and paresthesia at admission. Radiologic studies of the cervial spine showed an aggressive osteolysis of C4 vertebral body, pedicle and lamina with compression of the spinal cord posteriorly on C3, C4, C5 levels. The tumor was totally removed by a combined anterior and posterior approach. The removed vertebral body was replaced with autogenous bone and stabilized by Codman locking plate symtem. The pathological examination showed characteristic of mesenchymal chondrosarcoma.previous symptoms well improved postoperatively. The authors present a case of mesenchymal chondrosarcoma with review of literature.

PURPOSE: Return of spontaneous circulation (ROSC) is closely related to a favorable treatment outcome in out-of-hospital cardiac arrest and is also a reliable treatment target in clinical trials. The aim of this study is the identification of major factors affecting field ROSC by analyzing the updated data encompassing the pre-hospital treatment processes. METHODS: This is a retrospective review of cardiopulmonary resuscitation (CPR) cases performed by 119 rescuers before hospital arrival from January 2012 to December 2014 in one province. Cases with traumatic cardiac arrest, unnecessary CPR, arrest occurred during transport, under age 14 years, and incomplete medical records were excluded. RESULTS: Of 1,832 patients enrolled in the study, ROSC was achieved in 99 cases (5.4%). Among them, 50 (50.5%) had ROSC at the event field and others achieved ROSC during the transport process, respectively. Total cases were divided into two groups based on ROSC before arrival at the hospital. Age, underlying cardiovascular illnesses, the event place, presence of a witness, bystander CPR, application of an automated external defibrillator (AED), the initial shockable rhythm, defibrillation, advanced airway, hydration, the arrival time of rescuer CPR, application time of AED, and defibrillation showed significant statistical differences. In multivariate analysis, age, defibrilOf 1,832 patients enrolled in the study, ROSC was achieved in 99 cases (5.4%). Among them, 50 (50.5%) had ROSC at the event field and others achieved ROSC during the transport process, respectively. Total cases were divided into two groups based on ROSC before arrival at the hospital. Age, underlying cardiovascular illnesses, the event place, presence of a witness, bystander CPR, application of an automated external defibrillator (AED), the initial shockable rhythm, defibrillation, advanced airway, hydration, the arrival time of rescuer CPR, application time of AED, and defibrillation showed significant statistical differences. In multivariate analysis, age, defibrillation, hydration, bystander CPR, and the call-to-rescuer CPR interval appeared to be correlated with field ROSC. CONCLUSION: To improve the survival rate through field ROSC, a public campaign to improve bystander CPR, prompt recognition of cardiac arrest, and rapid application of pre-hospital treatment and political support of the public institution are mandatory.

PURPOSE: When pneumothorax occurs during a percutaneous needle biopsy, the radiologist usually stops the biopsy. We evaluated the usefulness of computed tomographic (CT) fluoroscopy-guided percutaneous needle biopsy in the presence of pneumothorax during biopsy. MATERIALS AND METHODS: We performed 288 CT fluoroscopy guided percutaneous needle biopsies to diagnose the pulmonary nodules. Twenty two of these patients had pneumothorax that occurred during the biopsy without obtaining an adequate specimen. After pneumothoax occurred, we performed immediate CT fluoroscopy guided percutaneous needle biopsies using an 18-gauge cutting needle. We evaluated the success rate of the biopsies and also whether or not the pneumothorax progressed. We classified these patients into two groups according to whether the pneumothorax progressed (Group 2) or not (Group 1) by measuring the longest distance between the parietal pleura and the visceral pleura both in the early and late pneumothorax. Additionally, we analyzed the relationship between the progression of pneumothorax after biopsy and 1) the depth of the pulmonary nodule; 2) the number of biopsies; 3) the presence or absence of emphysema at the biopsy site; and 4) the size of the pulmonary nodule. RESULTS: Biopsy was successful in 19 of 22 nodules (86.3%). Of the 19 nodules, 12 (63.2%) were malignant and 7 (36.8%) were benign. Twelve patients (54.5%) were classified as group 1 and 10 patients (45.4%) as group 2. The distance between the lung lesion and pleura showed a statistically significant difference between these two groups: < or = 1 cm in distance for group 1 (81.8%) and group 2 (18.2%), and > 1 cm in distance for group 1 (30%) and group 2 (70%), p < 0.03. Yet the number of biopsies, the presence or absence of emphysema at the biopsy site and the size of the pulmonary nodules were not related to the progression of pneumothorax (p > 0.05). CONCLUSION: When early pneumothorax occurs during a biopsy, CT fluoroscopy guided percutaneous needle biopsy is an effective and safe procedure. Aggravation of pneumothorax after biopsy is affected by the depth of the pulmonary nodule.
