We report two cases of linear focal elastosis. They are a 16-year-old girl and a 14-year-old boy who had had asymptomatic, several, yellow-red, slightly elevated, palpable, striae-like lesions on their middle and lower back since their early childhood. Light microscopic examinations of skin biopsy specimens demonstrated dermal thickening and focal increases of thin wavy fibers in the upper and mid-dermis but no changes in the epidermis. Verhoeff-van Gieson stains for elastic fiber revealed aggregated, clumped, curled, or fragmented elastic fibers.

Trichilemmal carcinoma is a rare tumor that is located predominantly on sun-exposed skin of the elderly. It is thought to be related to the external root sheath of the hair follicle and the malignant counterpart of a trichilemmoma. We report a case of trichilemmal carcinoma in a 88-year-old woman who had a 10 year history of a single, dark brown tumor on the right preauricular region. In her past medical history, it had been excised twice at a private clinic without a histopathological evaluation and recurred 2 years later. Histopathological findings showed atypical clear cells resembling those of the outer root sheath. Tumor cells showed PAS-positive cytoplasm. Immunohistochemistry revealed positive high molecular weight cytokeratin expression. To our knowledge, this is the second case of trichilemmal carcinoma in the Korean literature.

STUDY DESIGN: This was a retrospective study to evaluate anterior cervical interbody fusion with plates. OBJECTIVE: To examine the degree of angulation and translation after an anterior interbody fusion, using anterior plate fixation, upon the fusion rate and clinical outcome. SUMMARY OF LITERATURE REVIEW: Anterior cervical interbody fusion with plate allows immediate rigid internal fixation after decompression and bone grafting. MATERIALS AND METHODS: 65 cases had an anterior interbody fusion on the cervical spine, using an anterior approach and Smith-Robinson's method, between January 1998 and August 2003. Of these, 41 cases, which could be followed up for at least one year, were selected. There were 26 and 15 males and females, respectively, with an average age of 43.5 and mean follow up period of 2.1 years. 15 cases underwent an operation due to dislocation or fracture of the cervical spine due to trauma, and 26 due to cervical diseases. The angulation and translation of the plate was measured by postoperative X-rays. The fusion rate was also determined by the follow up X-rays. The Chi-squared test was used to analyze the data. RESULTS: Bony fusion was obtained in all cases. Two patients developed hoarseness and one showed torticollis, but all had recovered by the follow up. The average angulation of the plate and translation were 6.2 degrees and 3.21mm, respectively, but there was no significant difference of the interbody fusion period due to angulation and translation of the plate or in the improvement of the clinical outcomes. CONCLUSION: In the cases of anterior interbody fusion of the cervical spine, the angulation and translation of the plate had no influence on the fusion time and clinical outcomes. Long term studies and research will be needed to bring about clinically more valuable data.

Bronchopleural fistula is an uncommon but serious complication of lung resection, with a high mortality and morbidity. Problems associated with bronchopleural fistula and empyema are related to positive-pressure ventilation, which may result in infectious contamination of healthy lung tissue, loss of air, decreased alveolar ventilation leading to carbon dioxide retention, and the development of a tension pneumothorax. We experienced difficult intubation in patient who has large bronchopleural fistula and anatomic deviations of intact bronchus of the left lung, so we used a long single lumen tube made by attaching an another cuffed endotracheal tube under direct vision. The arterial oxygenation was effective, but carbon dioxide elimination was inadequate. After the operation, the ordinary cuffed endotracheal tube was intubated orally and the patient was transferred to the ward without problems 6 days after the operation.

Korean Journal of Dermatology 1999;37(11):1617-1626
BACKGROUND: Cellulitis is a suppurative inflammation involving particularly the subcutaneous tissue. There has been no data about its clinicopathologic features in Korea. OBJECTIVES: The purpose of this study was to investigate the clinicopathologic characteristics of cellulitis and to assess the yield rate of special stainings (Brown-Brenn, Gram) for organisms. METHODS: We reviewed the medical records and histologic sections of 45 patients who had been diagnosed as cellulitis in the Department of Dermatology, Chungbuk National University Hospital from January 1992 to August 1998. RESULTS: The results were as follows. 1. The sex ratio of male to female was 1.5:1 and average age was 43 years old. 2. The lower extremity was the most frequently involved site of cellulitis with a frequency of 53.4%. 3. Erythema, tenderness, local heating, swelling, and pain were almost always presenting clinical manifestations. 4. Diabetes mellitus was the most frequent underlying systemic disease. 5. The route of infection was suspected in 25 cases(55.6%). Tinea pedis was strongly suspected in 7 cases(28.0%), and followed by insect bite in 5 cases(20.0%), herpes zoster in 4 cases(16.0%), and trauma in 2 cases(8.0%). 6. The main complications were orthopedic problems including bursitis, osteomyelitis, and septic arthritis. 7. Microorganisms were isolated in 20 of 43 tissue cultures(46.5%). 8. It is important to suspect Escherichia coli as a causative organism if blistering cellulitis occurs, especially in patients with underlying systemic disease. 9. The most frequent histopathologic findings were perivascular lymphohistiocytic infiltrations in both dermis and subcutaneous fat simultaneously without vasculitis. 10. Special stainings(Brown-Brenn or Gram) were worthy to try, especially in the neutrophilic dominant cellulitis. 11. First-generation cephalosporin was chosen as primary antibiotics in 31 cases, and there was no difference in clinical course between its monotherapy and combined therapy. 12. Twenty percent of cases experienced recurrences. Lower extremity was most common site of recurrence(63.6%). CONCLUSION: Diabetes mellitus and tinea pedis were so closely bound up with cellulitis that control of those diseases is important in view of the clinical course of cellulitis. Special stainings(Brown-Brenn or Gram) were worthy to try, especially in the neutrophilic dominant cellulitis.

OBJECTIVE: Brachial plexus injury can produce a intractable chronic neuropathic pain. This study was undertaken to assess the long term outcome of microsurgical dorsal root entry zonotomy(MDT). METHODS: Between October 1997 and December 2002, 21 patients received MDT because of a intractable pain resulting from brachial plexus injury. Of these, 19 patients were followed for more than 2 years. Fourteen of 19 patients were male and patient ages ranged from 22 to 69 years. Mean pain duration was 36.8 months and all patients had severe pain of 9~10 visual analogue scale. To achieve complete destruction of abnormal dorsal horns, thermocoagulation of the posterolateral sulcus were performed and careful gluing was done to prevent postoperative adhesion and pain recurrence. RESULTS: Of the 19 patients, 15 patients had excellent (>75% reduction in pain) and good (51~75% pain relief) results in a average postoperative period of 4.1 years. One patient had a poor (less than 25% pain relief) result. Three patients were considered to have a fair result (26~50% pain relief). Postoperative complications were 2 transient ipsilateral ataxia and 1 CSF fistula that resolved without surgical revision. CONCLUSION: These results indicate that MDT provides excellent long-term pain relief in medically intractable chronic neuropathic pain following brachial plexus injury without significant complications.

STUDY DESIGN: The changes of the disc height in patients diagnosed with lumbar disc herniation who underwent a discectomy were subjected to a retrospective study. OBJECTIVES: The goal of this study was to find the relationship between the disc height and degenerative disc changes in patients diagnosed with lumbar disc herniation who underwent a discectomy. SUMMARY OF LITERATURE REVIEW: Disc height changes according to age, degenerative change and the amount of removed disc. MATERIALS AND METHODS: The patients in this study were those diagnosed with HNP who undergone a discectomy in our hospital. The fifty seven observed patients had a discectomy in our hospital between March, 2001 and March, 2003. Patients who had posterior fusion during surgery were excluded. There were 35 males and 22 females, with an average age of 35.9 yrs old (17-55) and a mean follow-up period of 2.7 yrs. The degrees of HNP and degenerative disc were examined with MRI and measured through the T2 MRI, respectively, before the operation. The disc heights were measured before and after surgery, and the anterior, posterior and middle disc heights were measured with a simple lumbar lateral X-ray. There were 6, 20, 25 and 6 cases of degeneration grades II, III, IV and V, respectively. There were also 27, 25 and 5 cases of protruded, extruded and sequestrated discs, respectively. RESULTS: When patients with a lumbar disc herniation underwent a discectomy, the changes of disc height in people of those with a postoperative degenerative disc change were notable, but there was no difference in disc height change with regard to the degree of HNP. CONCLUSION: In lumbar disc herniation patients after a discectomy, the changes of disc height decrease significantly in severe degenerative discs in the short term; therefore, further long term periods of study will be required.

OBJECTIVES: Immunologic studies have characterized the numbers and types of inflammatory cells in diseased inflammatory bowel disease (IBD) mucosa but have yielded conflicting results regarding intestinal lymphocytes activation in IBD. We investigated the levels of lymphocytes subsets, interleukin-2 receptor, transferrin receptor, and T cell receptors in mainly isolated lamina propria lymphocytes. Including intraepithelial lymphocytes of normal colonic mucosa or IBD (ulcerative colitis and Crohn's disease) mucosa to understand the pathogenesis of IBD. We have results from this study. RESULTS: 1) In comparing ulcerative colitis with control, IL-2R (p < 0.05), TR (p < 0.01), and CD3/HLA-DR (<0.05) showed a significant increase. 2) In comparing Crohn's disease with control, CD3 (P < 0.05), TCR alpha/beta (p < 0.01) and TCR gamma/delta (p < 0.05) showed a significant decrease. 3) In comparing Crohn's disease with ulcerative colitis, CD19 (p < 0.01), TR (p < 0.01), TCR alpha/beta (p < 0.01) and TCR gamma/delta (p < 0.05) showed a significant decrease. CONCLUSION: From these results, there are increased T cell markers, IL-2R, TR, and CD3/HLA-DR in UC, but differently, decreased CD3, TCR alpha/beta and TCR gamma/delta in CD compared with control. In addition, definitive differences in lymphocytes markers, CD19, TR, TCR alpha/beta and TCR gamma/delta, which are higher in UC than in CD, may elucidate the different immunopathogenesis between UC and CD.
