Lupus vulgaris is most prevalent on exposed parts, especially the face but can also develop on exetremities. Lupus vulgaris originates from tuberculosis elsewhere in the body by hematogenous, lymphatic, or contiguous spread. A 19-year-old male patient came to our department. The patient had had many recurrent oozing and verrucous plaques and crusts on the left foot for one year. A skin biopsy from the lesion on the left dorsum of the foot showed scattered well defined granulomas consisting of the epithelioid cell clusters with Langerhans and foreign body type giant cells in the mid dermis. Caseation necrosis was slight. There were no bacilli on AFB staining. The multi test CMI for tuberculin was highly positive. A chest X-ray did not show any abnormal findings. The presence of Mycobacterium tuberculosis DNA was demonstrated by polymerase chain reactions (PCR) for detection of mycobacterial DNA from a routinely prepared paraffin-embedded skin specimen. Herein we report a very atypical case of lupus vulgaris confirmed by PCR.

Infantile digital fibromatosis is a rare benign tumor on the fingers and toes of infants and childhood which is characterized by fibroblastic proliferation. Usually the lesions occur singly or severally on the dorsal or lateral aspects of the distal phalanges of the toes and fingers. The thumb and great toe are usually spared. These asymptomatic, firm, red, smooth nodules, some lcm diameter, occur during the first year of life. Forty-seven percent occur in the first month of life. This disease can occur after trauma. The lesions do not metastasize. Occasionally, spontaneous regression has been reported. After excision, recurrence can be possible. A 2 years old female infant had three large bean sized erythematous masses on the left 2,3,4th fingers. The erythematous aacule was developed at 6 months old and grew slowly. We could find inclusion body stained bright red with Massons trichrome and purple with PTAH in cytoplasm of fibroblast. The patient was treated with a simple excision followed by a skin graft. During 5 rnonths after operation, recurrence was not occurred.

Purpose: : Intensive care unit (ICU) diaries have been implemented across the international ICU community. This study aimed to comprehend the meaning and nature of the lived experience of patients’ families using the ICU diary in Korea. Methods: : This qualitative study adopted van Manen’s hermeneutic phenomenology. The participants comprised eight women and two men who were the family members of patients in the ICU for more than three days. Data were collected using in-depth interviews and observation from July 2018 to January 2019. Results: : Patients’ families who experienced the ICU diary recognized it with six beings according to time: a good idea, forgotten stuff, burdensome work, touching service, my stuff, and a thing in the memory. The ICU diary had three essential meanings for the families: communication, solace and hope, and a record of life. These findings were rearranged according to van Manen’s fundamental existential, and the lived things and lived others were remarkably confirmed. Conclusion : Patients’ families experienced various ICU diary forms over time and recognized an ICU diary as a means of communication. Therefore, the ICU diary is expected to be used as an intervention between families and healthcare providers in the ICU to support mutual communication.

PURPOSE: After cataracts, eye injuries are the second leading cause of visual impairment worldwide. But most eye injuries are preventable simply by wearing appropriate eye protection. In this study we evaluate factors leading to eye injury in a sample of emergency department (ED) patients. METHODS: This study was conducted with 424 isolated eye injury patients who visited our ED from January to December of 2008. The following data were reviewed; date of visit, characteristics of subjects, existing use of eyewear, relationship of injury to work, causative activity, location where the injury occurred, type of injury, disposition at ED discharge, length of hospital stay, and the existence of sequelae. Severe eye injuries were classified based on the type of injury, disposition at ED, remaining visual loss, and sequelae. RESULTS: Among the total 424 isolated eye injury patients, 411 cases were analyzed. Eye injuries occurred most frequently at home (22.6%), in a factory workplace (21.2%), or an outdoor agricultural workplace (18.2%). The incidence of eye injuries peaked in the fifth decade of life. Among the 306 (74.5%) cases that were workplace unrelated, the main causative activities were assault (18.0%), injury associated with play (14.1%), sports (11.1%), and lawn mowing (9.2%). CONCLUSION: The most common location where the eye injury occurred was at home. Eye injuries prevention in the workplace is well promoted, but in fact, eye injuries were more common at home and during non-occupational activities. We suggest that public education programs which highlight non-occupational eye injury risk and prevention measures should be instituted to reduce preventable eye injuries.

OBJECTIVE: Performing high quality cardiopulmonary resuscitation (CPR) is important for improving the survival rate with a good neurological outcome and fewer complications. The retention of accurate CPR knowledge is essential for providing high quality CPR. This study examined the effects of chest compression only CPR training on the retention of correct CPR knowledge. METHODS: In December 2016, an interview survey to target the study population was conducted by trained interviewers, using a structured questionnaire. The respondents' general characteristics, status of CPR education, and knowledge and willingness regarding CPR were investigated. Pearson's chi-square tests and multivariate logistic regression analyses were used to determine which education-related factors affected the correct skill knowledge of performing CPR. RESULTS: Among the respondents, there are 80 persons (17.4%) who answered correctly in the questions regarding the skills of performing CPR. The respondents who had a willingness to perform CPR to family and strangers were 90.2% and 44.9% respectively. Through multivariable analysis, the factors related to correct skill knowledge in performing CPR in the didactic with practice group were people who had undergone CPR training within 2 years (odds ratio [OR], 2.293; 95% confidence interval [CI], 1.311–4.009), and person who had undergone chest compression only CPR training (OR, 2.044; 95% CI, 1.033–4.042). CONCLUSION: Chest compression only type of CPR training and the experience of CPR education within 2 years were associated with accurate skill knowledge of performing CPR.

PURPOSE: This study was conducted to evaluate the length of the catheter used in a needle thoracostomy for emergency decompression of a tension pneumothorax by measuring the chest wall thickness (CWT) in patients with chest trauma METHODS: A retrospective review of 201 patients with chest trauma who had been transported the emergency department in a tertiary university hospital in a metropolitan area between 1 January and 31 February 2007 was performed. The average CWT at the second intercostal space (ICS) in the midclavicular line (MCL) was measured by using a chest computed tomography scan. RESULTS: As the left and the right mean CWTs were 3.4+/-1.0 cm and 3.4+/-1.0 cm, respectively, there was no significant statistical difference between them. The mean CWT of female patients was significantly higher than that of male patients (p=0.001). The mean CWT of patients under the age of 65 years was significantly thicker than that of the patients over the age of 65 years (p<0.001). Of the studied patients, 12 (6.0%) a CWT > 5 cm. CONCLUSION: A 5 cm-length catheter in a needle thoracostomy may be insufficient for emergency decompression of a tension pneumothorax, so a catheter longer than 5 cm in length is needed.

UV radiation is known to cause photoaging of the skin and is considered one of the leading cause of developing skin carcinogenesis. Melatonin which has a highly lipophilic molecular structure facilitating penetration of cell membranes and serving as an extra- and intracellular free radical scavenger has been demonstrated to protect photodamage of skin affected by UV exposure. In this study, we have examined the role of melatonin in response to UVB induced photodamaging process, using human skin fibroblasts in vitro. Cell survival curves after UVB irradiation showed dose-dependent decrease. Only 60% of fibroblasts were survived at 140 mJ/cm2 UVB irradiation. By pre-cultivation of cells with melatonin (100 nM), a significant number of cells remained unaffected. After UVB irradiation with 70 mJ/cm2, the level of putrescine was 1.7+/-0.3 fold increased compared to melatonin pre-treated group. In Northern analyses, the transcriptional level of ornithine decarboxylase (ODC) gene expression was increased by UVB irradiation and prohibited by melatonin. These results indicated that melatonin was effectively able to neutralize membrane peroxidation when present in relevant concentration during UVB irradiation and diminishes the UVB-induced increase of polyamine synthesis and ODC gene expression. Collectively, ODC response to UVB induced changes are possibly involves a melatonin or antioxidant sensitive regulatory pathway in normal human skin fibroblast.

PURPOSE: The following study was performed to compare basic life support (BLS) skills and knowledge over a 6 months interval in preclinical medical students. METHODS: Upon initial instruction, 112 first-year medical students at a teaching hospital were given instructions in BLS, their knowledge performance was evaluated by written test and skills test via checklist designed by instructors and PC SkillReporting System(R) (Laerdal, Norway). Their performance was re-evaluated 6 months after initial BLS training in an identical fashion. Evaluation was performed on 103 out of 112 students who had taken initial BLS training. RESULTS: The results of written test showed that the students evaluated right after taking initial BLS training have better knowledge of BLS compared to students evaluated 6 months after taking initial BLS training (p<0.001). Results of skills test evaluated by checklist showed decrease in adequate performance of students evaluated 6 months after BLS education in 12 out of 18 items compared to students who have just received initial BLS training. The decreases were statistically significant in 6 items. Total scores after 6months were also lower compared with initial scores (p<.0.001). The results of the skills test using PC Skill Reporting System(R) demonstrated that the percentage of adequate ventilation volume, compression rate, hands-off time, and hand position were each 18.4%, 46.6%, 47.6%, 84.2% initially and 5.8%, 32.0%, 32.0%, 76.1% at 6 months after initial training. Students performed significantly worse 6 months post training in 4 out of 7 items (p<0.05). CONCLUSION: Knowledge and skills of preclinical medical students decreased significantly after a 6 month period compared to knowledge and skills after initial training. Therefore, retraining of BLS is required within 6 months, but more study is required to determine appropriate intervals and methods of retraining.

PURPOSE: The authors conducted a multicenter study to evaluate the efficacy and safety of combination chemotherapy with Padexol(R) and cisplatin for treating patients with advanced non-small cell lung cancer (NSCLC). MATERIALS AND METHODS: From November 2003 to April 2005, 42 chemo-naive patients with advanced NSCLC were enrolled into this study from 4 hospitals. The treatment consisted of Padexol(R) 175 mg/m2 as a 3-hr infusion, and this was followed by cisplatin 75 mg/m2 administered as an intravenous infusion with standard premedication. The treatment was repeated every 3 weeks. RESULTS: Among the 42 patients (pts), 33 pts were evaluable for response. On the per protocol analysis, 1 patient (pt) (3.0%) achieved complete response (CR), 17 pts (51.5%) achieved partial response (PR), 6 pts (18.2%) achieved stable disease (SD), and 9 pts (27.3%) progressed; therefore, the overall response rate was 54.6% (95% CI: 37.6~71.5%). On the intention-to-treat analysis, 1 pt (2.4%) achieved CR, 18 pts (42.9%) achieved PR, 11 pts (26.2%) achieved SD, and 9 pts (21.4%) progressed; therefore, the overall response rate was 45.2% (95% CI: 30.2~60.3%). The response, as evaluated by the investigators, was independently reviewed by 2 external radiologists and it was as follows; 13 PR (43.3%), 14 SD (46.7%) and 3 progressive disease (10%). The median duration of response was 5.9 months. The median follow-up duration was 10.3 months (range: 1.3 to 22.1 months). The median time to progression was 5.8 months (95% CI: 4.7 to 7.4 months). The median survival time on the intention-to-treat analysis was 10.5 months (95% CI: 8.1 to 18.8 months). The most common grade 3 or 4 hematologic toxicities were neutropenia (26/180 cycles, 14.4%), anemia (7/180 cycles, 3.9%) and febrile neutropenia (2/180 cycles, 1.1%). The most frequent grade 3 or 4 non-hematologic toxicities were nausea (14/42 patients, 14.3%), anorexia (3/42 patients, 7.1%) and myalgia (3/42 patients, 7.1%). CONCLUSION: The authors observed that Padexol(R) was as good as the other paclitaxel (Taxol(R) or Genexol(R)) formulations when combined with cisplatin for treating patients with advanced NSCLC.

PURPOSE: This research was conducted to study whether the specific location of pelvic-bone fractures could increase the risk for injury to the urinary bladder, urethra, or lower gastrointestinal tract. METHODS: We retrospectively reviewed the data of 234 patients with pelvic-bone fractures who visited the emergency department of Kyungpook National University Hospital from January 2004 to December 2006. The location of the pelvic-bone fracture was divided into 8 parts. The association of fracture location with injury to the urinary bladder, urethra, or lower gastrointestinal tract was analyzed with Fisher's-exact test and multiple logistic regression. RESULTS: Nineteen(19) patients had urinary bladder injury, 8 had urethral injury, and 9 had lower gastrointestinal tract injury. The following fracture locations were found to be significant; urinary bladder: sacroiliac (SI) joint (p<0.001), symphysis pubis (p=0.011), and sacrum (p=0.005); urethra: SI joint (p=0.020); lower gastrointestinal tract: symphysis pubis (p=0.028). After the multiple logistic regression analysis, the primary and the independent predictors for each of the injuries were as follows; urinary bladder: sacroiliac joint (p=0.000, odds ratio [OR]=10.469); lower gastrointestinal tract: symphysis pubis (p=0.037, OR=7.009). CONCLUSION: Consideration of further workup for injuries to the lower gastrointestinal and urinary tract is needed for some locations of pelvic-bone fractures because certain pelvic-bone fracture locations, especially the sacroiliac joint and the symphysis pubis, are associated with increased risk for injury to the lower gastrointestinal and urinary tracts.
