PURPOSE: In colon cancer, the most frequent genetic alteration is found in p53 tumor suppressor gene residing on the short arm of chromosome 17. In order to investigate the significance of wild-type p53, we transfected wild type p53 into human colon cancer cell lines and analysed tbeir biologic effects. MATERIALS AND METHODS: For analysis of p53 status in cell lines, polymerase chain reaction-single stranded confonnation polymorphism (PCR-SSCP), PCR-direct sequencing and Western blot analysis were employed. Transient transfection with liposome-p53 complex was followed by cell biologic assay. RESULTS: We found that twelve of fifteen human colon cancer cell lines showed mutation of p53 by PCR-SSCP method. These results almost corresponded to p53 protein accumulations assessed by Westem blot using PAbl801. After transfection with lipafect- AMINE and wild type p53 complex on p53 mutant type cell line (LS1034), viability was reduced to 17.9%, and invasiveness was reduced to 37.3%. Morphologically, wild type p53 transfected cells showed lumen formation and apoptosis after induction of differentiation by Matrigel. CONCLUSION: Wild type p53 transfection into p53 mutated colon cancer ceil line resulted in restoration of tumor suppressor effect of p53, and this model would be one of the experimental systems for p53-based gene therapy.

Phakomatosis pigmentovascularis is a rare cutaneous malformation characterized by a combination of nevus flammeus and pigmentary nevus such as nevus of Ota, nevus of Ito, mongolian spots, nevus spilus. It is often associated with systemic organ involvement. We report two cases of phakomatosis pigmentovascularis. The first was a 11-year-old boy, who had had diffuse nevus flammeus, mongolian spots since birth, and congenital glaucoma. The second case was a 9-year-old boy who had had nevus flammeus, mongolian spots, nevus of Ota, and nevus of Ito over various parts of his body since birth. He also had leg-length discrepancy, avascular necrosis of the femur head, congenital temporal alopecia and varicose veins.

Upper extremity deep vein thrombosis (DVT) is an unusual condition compared to lower extremity DVT, and it represents about 10% of all DVTs. We report a case of upper extremity DVT after clavicle fracture and immobilization.

Traumatic blunt aortic injury especially on proximal ascending aorta is a rare injury with a few reports. Generally emergency surgical management was performed. In this case, however, in multiple trauma with brain injury, emergency surgical management of aortic injury might result in unexpected secondary injury of the brain. Herein, we report a case of a 33-year-old man who was driving a truck was injured in a head-on collision. Evaluation revealed a pseudoaneurysm on his ascending aorta concomitant with epidural hemorrhage. He was treated by surgical management of his ascending aorta after 3 days from accident. There were no postoperative and neurologic complications and the patient was discharged after 18 days.

PURPOSE: The incidence of overactive bladder (OAB) and the efficacy of alpha blocker and tolterodine combination therapy were examined in patients with symptomatic benign prostatic hyperplasia (BPH). MATERIALS AND METHODS: Between March 2001 and December 2001, 144 BPH patients were subdivided into those with BPH, or BPH with OAB, based on urodynamic studies. All patients were treated with alpha blockers for 3 months. Patients with no symptomatic improvement were treated with alpha blockers and tolterodine for 2 months. An increase in the International prostate symptom scores (IPSS) of more than 3 points after medication was considered an improvement, but if not, as a failure. RESULTS: Of the 144 patients, 76 (53%) had BPH and 68 (47%) had BPH with OAB. The patients with BPH and OAB were older (p<0.05), but no differences were observed in the serum creatinine, IPSS, prostate volume, maximum flow rate or post-void residual urine (PVR) between the 2 groups. After 3 months treatment with alpha blockers, 79% (60/76) of the BPH and 35% (24/68) of the BPH with OAB patients had improved (p<0.05). Of the patients showing no improvement, 38% (6/16) with BPH and 73% (32/44) with BPH and OAB showed improvement after the addition of tolterodine. CONCLUSIONS: The combination therapy was more effective than alpha blockers alone in the treatment of patients with coexisting BPH and OAB. We recommend identifying these patients with an initial urodynamic study, which allows for the appropriate management and identification of those patients that may benefit from a more invasive treatment.

BACKGROUND: The aim of this study was to analyze the gender factors associated with good or bad prognosis after return of spontaneous circulation after out-of hospital cardiac arrest. METHODS: The patients admitted to the intensive care unit after successful resuscitation after out-of hospital cardiac arrest were retrospectively identified and evaluated. Thirty days mortality after admission, and neurologic outcome at 6 months after hospital discharge (cerebral performance category [CPC]) were evaluated. RESULTS: One hundred forty-two patients were evaluated in this study; there were 101 males (71.1%). The median age was 52 years old (43-63). Thirty days after admission, 85 patients (59.9%) survived, 40 patients had a good neurologic outcome (CPC 1-2). The factors associated 30 days mortality were cause of arrest (non-cardiac, p = 0.03), lactate in emergency department (p = 0.05) and the factors associated with good neurologic outcome were males (p = 0.007), young age (p = 0.01), body weight and height (p = 0.001), cause of death (cardiac, p = 0.000). Alcohols and smoking were not associated with mortality and neurologic outcome. In multiple logistic regression analysis, men had a 8-fold increased good neurologic outcome (CPC 1-2) (odds ratio [OR] 8.038, 95% Confidence Interval [CI] 1.079-59.903). Other factors associated with good neurologic outcome were cardiac cause of death (OR 5.523, 95% CI 1.562-19.533) and young age (OR 1.055, 95% CI 1.009-1.103). CONCLUSIONS: Men had a good neurologic outcome after return of spontaneous circulation after out-of hospital cardiac arrest in one emergency center. Other additional factors including gonadal hormones should be evaluated.

Objective:
To examine the features of powered mobility device-related injuries and identify the predictors of injury severity in such settings.
Methods:
Emergency Department-based Injury In-depth Surveillance data from 2011 to 2018 were used in this retrospective study. Participants were assigned to the mild/moderate and severe groups based on their excess mortality ratio–adjusted injury severity score and their general injury-related factors and injury outcome-related factors were compared.
Results:
Of 407 patients, 298 (79.2%) were assigned to the mild/moderate group and 109 (26.8%) to the severe group. The severe group included a higher percentage of patients aged 70 years or older (43.0% vs. 59.6%, P=0.003), injuries incurred in the daytime (72.6% vs. 82.4%, P=0.044), injuries from traffic accidents and falls (P=0.042), head injuries (38.6% vs. 80.7%, P<0.001), torso injuries (16.8% vs. 32.1%, P=0.001), overall hospital admission (28.5% vs. 82.6%, P<0.001), intensive care unit admission (1.7% vs. 37.6%, P<0.001), death after admission (1.4% vs. 10.3%, P=0.034), and total mortality (0.7% vs. 9.2%, P<0.001). The odds ratios (ORs) for injury severity were as follows: age 70 years or older (OR, 2.124; 95% confidence interval [CI], 1.239–3.642), head injury (OR, 10.441; 95% CI, 5.465–19.950), and torso injury (OR, 4.858; 95% CI, 2.495–9.458).
Conclusion
The proportions of patients aged 70 years or older, head and torso injuries, injuries from traffic accidents and falls, and injuries in the daytime were higher in the severe group. Our results highlight the need for measures to address these factors to lower the incidence of severe injuries.
