BACKGROUND: Interferon alpha-2a has already been shown to be effective in clinical use of virus-originated diseases such as hairy cell leukemia, condyloma acuminatum, and AIDS-related Kaposi's sarcoma. The use of recombinant alpha-interferon may allow common warts to be treated relatively atraumatically and with less incidence of recurrence. OBJECTIVE: We tried to determine the safety and effectiveness of intralesional injections of recombinant alpha-2a interferon in the treatment of patients with common warts. METHODS: A single wart on each patient was weekly injected with 0.75 to 1.5×10(5) IU/25mm2 of interferon for 8 weeks, and the response to treatment was followed up-to 6 months. RESULTS: Clearing of the treated wart at the end of treatment occurred in 5(71%) out of 7 patients and the rest showed no improvement. With evaluation for relapses up-to 6 months after treatment, warts relapsed in 2(40%) out of 5 patients. Therefore, 3(43%) out of 7 patients were completely free of warts 6 months after treatment. CONCLUSION: Intralesional recombinant interferon alpha-2a has a limited therapeutic effect, but may be considered as a therapeutic modality of recalcitrant verruca or when it can be anticipated that destructive techniques or blistering agents will not be tolerated.

BACKGROUND: We conducted this study to verify whether a mechanical ventilator is adequate for cardiopulmonary resuscitation (CPR). METHODS: A self-inflating bag resuscitator and a mechanical ventilator were used to test two experimental models: Model 1 (CPR manikin without chest compression) and Model 2 (CPR manikin with chest compression). Model 2 was divided into three subgroups according to ventilator pressure limits (P(limit)). The self-inflating bag resuscitator was set with a ventilation rate of 10 breaths/min with the volume-marked bag-valve procedure. The mode of the mechanical ventilator was set as follows: volume-controlled mandatory ventilation of tidal volume (Vt) 600 mL, an inspiration time of 1.2 seconds, a constant flow pattern, a ventilation rate of 10 breaths/minute, a positive end expiratory pressure of 3 cmH2O and a maximum trigger limit. Peak airway pressure (P(peak)) and Vt were measured by a flow analyzer. Ventilation adequacy was determined at a Vt range of 400-600 mL with a P(peak) of < or = 50 cmH2O. RESULTS: In Model 1, Vt and P(peak) were in the appropriate range in the ventilation equipments. In Model 2, for the self-inflating bag resuscitator, the adequate Vt and P(peak) levels were 17%, and the P(peak) adequacy was 20% and the Vt was 65%. For the mechanical ventilator, the adequate Vt and P(peak) levels were 85%; the P(peak) adequacy was 85%; and the Vt adequacy was 100% at 60 cmH2O of P(limit). CONCLUSIONS: In a manikin model, a mechanical ventilator was superior to self-inflating bag resuscitator for maintaining adequate ventilation during chest compression.

Stable angina is a chronic, systemic disease with a wide range of associated symptoms and clinical outcomes. Prompt diagnosis can be challenging for clinicians. Typical chest pain caused by stable angina occurs when the myocardium receives inadequate oxygen, resulting in myocardial ischemia. Various diagnostic tools including non-invasive tests such as coronary computed tomographic angiography and image-based stress tests have evolved over the last decade. An important factor in the selection of the proper diagnostic test for stable angina is assessment of the pre-test probability in the event of possible coronary arterial stenosis.

PURPOSE: We examined the changes in background and characteristics in freshmen in graduate medical school from 2009 to 2011. METHODS: We analyzed the responses to a self-questionnaire which were about sex, age, graduation, major, religion and etc. The data were analyzed by t-test, chi-square test. RESULTS: The freshman population in 2009 and 2011 year was 44% and 58.4% male, and 56% and 41.6% female; had a mean age of 27.3 and 27.4; 41.6% and 32.0% Christian, 33.6% and 47.2% atheist, 76.0% and 68.8% graduates; and 48.0% and 50.4% in the capital region, respectively. With regard to future career, 43.2% and 43.2% of freshmen responded clinical professor, 29.6% and 27.2% private clinics, 8.0% and 13.6% medical researcher, 8.8% and 6.4% public officer, 6.4% and 3.2% basic science faculty, and 4.0% and 6.4% others. With regard to future majors, 20.0% and 20.0% answered internal medicine, 11.2% and 8.0% psychiatrics, 8.8% and 8.8% general surgery, 8.0% and 8.8% pediatrics, 4.8% and 4.8% chest surgery, 33.6% and 36.0% others, and 13.6% and 13.6% undecided, respectively. CONCLUSION: The populations of males, atheists, graduation candidate, and medical researchers increased, those of females, Christian, and those born in Gwangju and Jeonnam decreased, and those of mean age, future careers and majors, birth place in the capital region were unchanged.

OBJECTIVE: Adult onset Still s disease is an acute systemic inflammatory disorder. There are no pathognomonic symptoms or specific laboratory abnormalities. In recent reports, serum ferritin concentration is increased in active disease phase and decreased after defervescence. Our purpose was to determine the clinical significance of serum ferritin as an indicator for disease activity. METHODS: Seven patients who were diagnosed as adult onset Still s disease at Samsung Medical Center between October 1994 and March 1997, were reviewed. In these patients we checked leukocyte count, ESR, CRP and serum ferritin concentrations at the time of diagnosis and during follow-up periods and recorded febrile events during follow-up periods. RESULTS: At the time of diagnosis and during febrile periods, the concentrations of ferritin were extremely high(927ng/ml to 96,650ng/ml normal 10-290.8 ng/ml). The values were unrelated to other manifestations of the disease or laboratory findings. The ferritin concentrations decreased rapidly after adequate treatment. Eleven febrile reattacks happened in 7 patients. Serum ferritin concentrations were increased in 8 febrile attacks, while leukocyte count, ESR, and CRP were increased in 5, 5, 6 febrile attacks respectively, There were 10 events of increased serum ferritin concentrations in 7 patients during follow-up periods and 8 events were related with fever. The increases of other laboratory tests were similar. CONCLUSIONS: In all patients, serum ferritin concentrations were increased at the time of diagnosis and closely related to fever. During follow-up periods, serum ferritin concentrations are helpful in monitoring disease activity and guiding decisions about treatment.

To investigate whether the prostatic biopsy specimen can be used for the estimation of total prostatic histologic ratio or not. we compared the relative volume density of glandular lumen from the open prostatectomy specimens with the relative area density of glandular lumen from the biopsied specimens in five patients with benign prostatic hypertrophy. We took four core biopsy specimens from each prostate. The overall correlation coefficiencies between volume densities and area densilies of each one to four combinations were 0.795, 0.898. 0.941 and 0.965 respectively. Furthermore. the probabilities of obtaining statistically significant values from each of one to four biopsy combinations were 50%, 65%, 100% and l00% respectively. In conclusion, the random biopsy specimens taken from more than three different sites would be enough to get the precise and reliable information about the histologic content of prostate.

Nevus sebaceus of Jadassohn has been referred to as a organoid nevus that classically evolves through three stages and may be associated with a range of skin tumors, and of these, syringocystadenoma papilliferum and basal cell carcinoma have been commonly reported to occur. The occurrence of keratoacanthoma is a very rare event in nevus sebaceus. Herein we report on a 23-year-old man with nevus sebaceus of the cheek. He represents a keratoacanthoma arising within nevus sebaceus.
