PURPOSE: To report a case of acquired lacrimal fistula caused by silicone tube remnant. CASE SUMMARY: A 56-years-old female who suffered from purulent discharge in inner skin of the right lower eyelid visited our clinic. Lacrimal fistula was found in the skin at the medial side of the right lower eyelid. The patient reported that she had a silicone tube intubation operation 3 years prior due to a nasolacrimal obstruction of right eye. On syringing test, saline solution and purulent discharge were drained from the fistula skin opening and there was no nasolacrimal obstruction. After admission, antibiotic treatment and potadine soaking dressing were performed to facilitate spontaneous closing of the lacrimal fistula. However, the lacrimal fistula relapsed and lacrimal fistulectomy and bicanalicular silicone tube intubation were performed. During surgery, silicone tube remnant material not totally extubated at the lacrimal sac was found which we removed. Postoperatively, systemic antibiotic therapy was administered and the chronic inflammation improved. CONCLUSIONS: We report a case of lacrimal fistula caused by silicone tube remnant in the lacrimal sac. Acquired lacrimal fistula caused by a silicone tube remnant can be treated by fistulectomy and silicone tube remnant removal.

We report a case of myelodysplastic syndrome (MDS) with unique histopathological findings in which numerous infiltrated neutrophils exhibited nuclear segmentation anomalies. In comparison with well-described neutrophilic dermatoses of myelodysplastic syndrome such as Sweets syndrome and pyoderma gangrenosum, this case took a rapid and aggressive clinical course. We suggest that a nuclear segmentation anomaly, pseudo Pelger-Hiiet anomaly, is likely to reflect acute transformation of MDS and can be a poor prognostic marker.

A clinical observation was performed on 2,122 cases of premature infants who were admitted to Ilsin Christian during the past 5 years from Jan. 1986 to Dec. 1990. The results were as follows; 1) The incidence of prematurity was 5.7%, overall mortality rate was 15.8%, and the sex ratio of male to female was 1.5:1. 2) Concomitant maternal diseases were premature rupture of membrane 457 cases (21.5%), preeclampsia & eclampsia 424 cases (19.9%), multiple pregnancy 250 cases (11.7%) etc, in the order of frequency. 3) Prematurity was most prevalent among multipara over 3. 4) Incidence of prematurity according to maternal age was frequent in woman more than 35 years old. 5) Mortality of prematurity was higher inversely propotional to birth weight & gestational age. 6) Main causes of death were IRDS 45 cases (43%), congenital anomaly 72 cases (21.6%), sepsis 31 cases (9.3%), and unknown 84 cases (25.0%). 7) Clinical problems were hyperbilirubinemia 38.9%, hypoglycemia 28.6%, IRDS 18%, sepsis & other infections 8.1% etc, in the order of frequency. 8) Most deaths were seen within first 24hr (74.5%).

The Bombyx mori decapentaplegic gene is one of the conserved genes in vertebrate and invertebrates. The TGF-beta superfamily contains conserved polypeptide growth factors that play important roles in different cellular processes such as proliferation, apoptosis, differentiation and cell-fate determination. The B. mori dpp gene shares genetic homology with hBMPs and Drosophila dpp. Until now, only few studies have been conducted to examine the functions of B. mori dpp; and hence, its function is not yet well understood. In this study, the baculovirus expression vector system (BEVS) was used for expression of the recombinant B. mori dpp protein and in which the recombinant baculovirus is recovered in the host Sf9 cells. The selected pure recombinant baculovirus containing B. mori dpp gene (rBV-egfp-Bm dpp) was used to increase the effective protein purification by using His-tag extraction strategy. After selection of recombinant baculovirus, recombinant B. mori dpp proteins were extracted from the re-infected cells with pure rBV-egfp-Bm dpp. Herein, we summarize the efficient expression and purification of B. mori dpp proteins from the insect cells using the BEVS. This recombinant protein could be suitable for functional test and various application studies.

BACKGROUND: The incidence of Cutaneous malignant tumors has increased recently and they have varied in their developing patterns according to social and environmental influences. However, we have little clinical data about the cutaneous malignant tumors in the Chonnam provinee. OBJECTIVE: Our purpose was to analyze the clinical characteristics of cutaneous malignant tumors observed in the Chonnam province and to compare them with the data previously reported in Korea. METHOD: We clinically analyzed 427 cases of cutaneous malignant tumors during a 10 year period betwecn January 1987 and Oetober 1996, at the Department of Dermatology, Chonnam Univemity Hospital in Kwangju. RESULTS: 1. The average armual incidence of cutaneous malignant tumors among the total number of outpatients was 1.00+/- 0.25%. The incidence tended to increase with time from 0.90+/-0.29% in the first 5 year-period to 1.15+/-0.09% in the late 5 year-period. The increasing rate was most pronmient in basal cell carcinoma. 2. The most common tumor in the 427 patients with malignant tumor was basal cell carcinoma (52.5%), followed by squamous cell carcinoma (19.9%), malignant melanoma (13.3%), metastatic carcinoma (3.7%), malignant lymphoma (2.3%). 3. The mean age of onset was 60.7+/-16.0 years old (male; 59.6+/-15.0, female; 61.9+/-17.1) in the in the group as a whole; 63.9 in BCC, 63.3 in SCC and 55.8 in malignant melanoma. The ratio of men to women was 1.14:l. 4. The most common site of a11 malignant tumors was the head and neck (64.6%), where 89.3% of BCC, 58.8% of SCC, and 15.8% of malignant melanoma developed. The next common site was the lower exlremities and feet (15.7%) followed by the trunk (7,7%), and upper extremities and hands (7.3%).

We report two cases of cellulitis on the saphenous venectomy scar which developed after a coronary artery bypass graft(CABG). A 68-year-old male and a 62-year-old female developed acute cellulitis in the saphenous vein donor extremity after CABG. The repeated bacterial cultures were negative in both cases. However, onychomycosis was confirmed in one patient. The intervals between CABG and the initial bout of cellulitis in the male and female patient were 10 and 22 months, respectively. Although the exact pathogenesis remains obscure, factors such as direct bacterial infection, hypersensitivity to streptococcal exotoxins, a local compromise of lymphatic and venous drainage, and fungal infection might have contributed to the development of cellulitis in these patients.

BACKGROUND/AIMS: The endoscopic mucosal resection has now been adopted for a useful modality in both curative therapy and accurate diagnosis of early gastric cancer. A retrospective study was done to evaluate the indication and the limitation of endoscopic mucosal resection of early gastric cancer. METHODS: We studied 20 cases of early gastric cancer treated by endoscopic mucosal resection in Chungnam National University Hospital from November, 1995 to July, 1997. RESULTS: 1) The size affected the curability: 83. 3% of lesions less than 2 cm and 50. 0% of those larger than 2 cm were resected completely. 2) The depth of cancer invasion affected the curability: 87. 5% of lesion confined to mucosa were resected completely, while all of submucosal cancers were resected incompletely. 3) Among fourteen cases resected completely, three cases of lesions larger than 2 cm were residual cancer and two of those less than 2 cm were recurred locally. CONCLUSIONS: To be a curative therapy by endoscopic mucosal resection of early gastric cancer, we think that careful selection of the lesion, that is lesion less than 2cm and confined to mucosa, is necessary
