From March 1987 to July 1989, six patients (five dadults and one child) with lung abscess (size, 5-13cm in diameter) were treated with percutaneous aspiration and drainage. In each case, the puncture was made where the wall of the abscess was in contact with the pleural surface. An 8 to 10 Fr catheter was inserted for drainage. Five of 6 had a dramatic clinical response within 24 hours of the drainage. Percutaneous drainage was successful with complete abscess resolution in four and partial resolution in one patient. No response was seen in the rest one. The duration of drainage ranged from 7 to 18 days (average, 15.5days) in successful cases. One case of the failure in drainage was due to persistent aspiration of the neurologically impaired patient. In one patient, the abscess resolved after drainage but recurred after inadvertent removal of the catheter 7 days after insertion. In two patients, concurrent pleural empyema was resolved completely by the drainage. Computed tomography provided anatomic details necessary for choosing the puncture site and avoiding a puncture of the lung parenchyma. Percutaneous catheter drainage is a safe and effective method for treating patients with lung abscess.

2.Trends of research articles in the Korean Journal of Medical Education by social network analysis.
Korean Journal of Medical Education 2015;27(4):247-254
PURPOSE: This aim of this study is to examine trends in medical education research in the Korean Journal of Medical Education (KJME) and suggest improvements for medical education research. METHODS: The main variables were keywords from research papers that were published in KJME. Abstracts of papers (n=499) that were published from 1991 through 2015 were analyzed by social network analysis (NetMiner 4.0) a common research method for trends in academic subjects. RESULTS: The most central keywords were "medical education," "clinical competence," "medical student," and "curriculum." After introduction into graduate medical school, newly appearing keywords were "professional behavior," "medical humanities," "communication," and "physician-patient relation." Based on these results, we generated a schematic of the network, in which the five groups before introduction to graduate medical school expanded to nine groups after introduction. CONCLUSION: Medical education research has been improving qualitatively and quantitatively, and research subjects have been expanded, subdivided, and specific. While KJME has encompassed medical education studies comprehensively, studies on medical students have risen in number. Thus, the studies that are published in KJME were consistent with the direction of journal and a new study on the changes in medical education is being conducted.

Macular hemorrhage which result from breaks of Bruch's membrane or from choroidal neovascularization can develop in high degenerative myopia, but its occurrence after photorefractive surgery has rarely been reported. We experienced a case of macular hemorrhage after laser in situ keratomileusis[LASIK]:A 28-year-old female patient with high myopia of -16.5 diopters, who had received successful LASIK operation on her left eye.complained of a sudden drop in vision 20 days postoperatively.On fundus examination, macular hemorrhages were detected on her left eye.Eventually the hemorrhages resolved, but more than 2 lines of her best corrected visual acuity were lost.During follow-up, a new hemorrhagic lesion was incidently found on the other eye. This case demonstrates that macular hemorrhages may develop after LASIK in eyes with high degenerative myopia, and lead to a permanent reduction in visual acuity.We should be alert to any potential retinal pathology in patients having refractive surgery.

PURPOSE: In the present study, a case of double fovea artifact on spectral-domain optical coherence tomography (SD-OCT) was reported. CASE SUMMARY: A nine-year-old male presented with blurred vision of both eyes. His best corrected visual acuity (BCVA) was 20/20 in both eyes, and complete ophthalmologic evaluation including fundus examination and fundus photography revealed no abnormality in both eyes. He underwent SD-OCT imaging with the Cirrus HD-OCT. The Macular Cube 512 × 128 protocol of his right eye revealed an unusual pseudo-duplication of the fovea in the vertical meridian. The same protocol in his left eye also rendered a pseudo-duplication of two foveas in the vertical and horizontal meridians on the retinal thickness map. Re-examination with the same OCT system and protocol was performed two weeks later after the patient received counseling on fixation during the examination, and it revealed normal contour of the fovea in both eyes. CONCLUSIONS: Double fovea artifact seen in SD-OCT is a rare artifact that can possibly lead to misdiagnosis and inappropriate clinical treatment. Since the artifact was resolved with better fixation of the patient, repeating the scan with better patient compliance is necessary when such an artifact is encountered.

BACKGROUND: Mycosis fungoides (MF) is the most frequent form of cutaneous lymphoma. Early stage MF is known to be responsible to the various topical and systemic therapies. However, there have been few clinical reviews of the treatment modalities of the early stoge MF in Korea. OBJECTIVE: The aim of this study is to investigate the therapeutic response of early MF to different treatment modalities. METHODS: The medical records, clinical photographs, and biopsied tissues, of fifty three cases of early MF were reviewed. RESULTS: The mean age at diagnosis of early MF was 43.0 years old (varied between 9 and 81 years old). Twenty three (43.4%) were male and thirty (56.6%) were female. Topical carmustine (bis-chloroethyl-nitrosourea, BCNU) was the most commonly used treatment modality in the early MF (34.0%). Patients treated by BCNU in stage IA (<10% skin involved) showed a response rate of 85.7%. Early MF recorred in only one patient after 93 months. However BCNU was not effective for the patients in stage IB (> or =10% skin involved). Even Psoralen plus UVA (PUVA) therapy, which was most efficient in stage IB, revealed a high relapse rate after one year. CONCLUSION: BCNU has been most commonly used for the treatment of early MF during the past 10 years in the authors' hospital. It showed a comparatively high response rate, and the relapse rate of BCNU was lower than for other therapies in stage IA. However many treatments became ineffective when MF progressed to stage IB. Therefore the authors confirm that early diagnosis and proper therapy are most important for the treatment of early MF.

rcinoma (SCC) is the second most common skin cancer. In particular, invasive SCC has a high risk of metastasis and sometimes, this can be fatal. At present, the treatment of choice for invasive SCC is complete excision with a proper surgical margin, but most cases of SCC develop on cosmetically-sensitive areas, so sometimes significant scarring or deformities can lead to an unhappy result. An 80 year-old female presented with a 4x1.5cm sized SCC on her lower lip. Although surgery was the first line therapy for this invasive SCC, a cosmetically poor outcome was expected. Thus the patient did not want to undergo a surgical operation, so we had to explore other treatment options. Recently there have been many reports that show imiquimod 5% cream is effective in the treatment of invasive SCC. Therefore we started topical therapy with imiquimod 5% cream five times a week. After 6 months, the lesion size was reduced to 2x1.5cm and we could remove the remnant tumor by wedge resection with cosmetically acceptable result. We suggest this neo-adjuvant immunotherapy can be an alternative for the treatment of cosmetically-critical SCC and present this case as a good example that has shown successful size-reductive neoadjuvant immunotherapy using imiquimod in invasive SCC.

Pyomyositis is an acute, suppurative bacterial infection of striated muscle. It occurs primarily, and not from contiguous infection. It is considered rare in temperate climates. There has been no report of pyomyositis in the Korean dermatologic literature to date. We report a case of pyomyositis which developed in a 53-year-old male. The patient was admitted for the treatment of cutaneous leukocytoclastic vasculitis on his entire body. He was treated with oral corticosteroids for approximately three weeks. The skin condition did show improvement; however, the patient developed a persistent fever and a newly-found mass on the right upper back. The mass was diagnosed as an abscess, replacing the striated muscles of the back by sono-guided needle aspiration. After surgical intervention and IV antibiotic treatment, the symptoms and mass on the back disappeared. We speculate that the underlying skin condition and long-term use of oral corticosteroids predisposed the patient to pyomyositis.
