Few cases of ichthyosis bullosa of Siemens(IBS) have been reported since 1939, as a distinct entity from bullous congenital ichthyosiform erythroderma(BCIE). IBS can be differentiated from BCIE by the absence of congenital erythroderma and a different distribution of involved skin area. It's characteristic features include blistering, superficial erosion or moulting of the outer skin. Histological features are tonofilaments aggregation confined to the granular and upper spinous layer of the epidermis. However, in BCIE these findings are present in the whole suprabasal compartment. The original reports of Siemens and cases from other authors showed an autosomal dominant inheritance. Our patient developed IBS sporadically without a familial background.

A clinical review of 212 cases of tuberculous cervical lymphadenitis during the past 6 years from January 1990 to December 1995 was made at the Department of General Surgery, Eul ji Medical College Hospital,Taejeon. The results are as follows: 1) The age of peak incidence was the 3rd decade (43.3%), and females predominated over males by 3.1 : 1. 2) The time interval from the onset of symptoms to the first visit was less than 3 months in 53.3% of the patients. 3) The location of lymphadenitis was the right neck in 59.9%, the left neck 38.7%, and bilateral in 1.4% of the patients. 4) Signs on the first visit were a mass, a cold abscess and/or a discharge. A palpable mass was the most frequent symptom (86.8%). 5) The incidence of associated pulmonary tuberculosis was 26.9%. 6) Seventy patients (33.0%) had a past history of tuberculosis. Among them, 55.7% had lymphadenitis, 28.6% pulmonary tuberculosis, and 15.7% medical problems at other sites. 7) Treatments of tuberculous cervical lymphadenitis were chemotherapy alone (68.4%) or surgical management combined with chemotherapy (31.6%). The surgical treatments included excision, incision and drainage, and neck dissection in 17.5%, 13.2%, and 0.9% of the patients, respectively. 8) The rate of recurrence was 3.1% (5 cases) for 160 cases, among them, 1.2% (2 cases) involved chemotherapy alone and 1.9% (3 cases) surgery with chemotherapy. The other 52 cases were lost from follow up.

Background: Epigenetic studies, particularly research on microRNA (miRNA), have flourished. The abnormal expression of miRNA contributes to the development of hematologic malignancies.miR-765 has been reported to inhibit cell proliferation by downregulating proteolipid protein 2 (PLP2), which causes apoptosis. We investigated miR-765 dysregulation in myelodysplastic syndromes (MDS). Methods: We compared the expression profiles of miR-765 in 65 patients with MDS and 11 controls.Cell proliferation and apoptosis assays were performed to determine the in vitro effects of miR-765 on leukemia cells transfected with the miR-765 mimic. Reverse transcription quantitative PCR (RT-qPCR) and western blotting were performed to examine the targets of miR-765. Results: We found that miR-765 levels were upregulated 10.2-fold in patients with MDS compared to controls. In refractory cytopenia with multilineage dysplasia, the percentage of patients with elevated miR-765 levels was significantly higher than in other forms of MDS.Experiments with leukemia cells revealed that transfection with a miR-765 mimic inhibited cell proliferation and induced apoptosis. RT-qPCR and western blotting demonstrated that the target of miR-765 was PLP2. Conclusion These findings imply that upregulation of miR-765 induces apoptosis via downregulation of PLP2 and may have a role in MDS pathogenesis.

PURPOSE: To describe plain radiographic and thin-section CT findings of hematogenous candida pneumonia in major burn patients. MATERIAL AND METHOD: We reviewed nine cases of hematogenous candida pneumonia in major burn patients who had positive blood culture for candida and findings of pneumonia on plain chest radiograph. On five of nine cases, thin-section CT was done. We evaluated retrospectively nine cases for onset, the pattern, distribution, and size of lesions on plain chest radiograph and thin-section CT. RESULTS: On plain chest radiograph, randomly distributed 2-10mm nodules were seen in six cases(66%) and randomly distributed 10-15mm consolidations in remaining three cases{33% ). Lesion occured in 11th to 75th post-burn day{average, 34th post-burn day). Other findings were cardiomegaly in three cases, atelectasis in three cases, and pulmonary edema in one case. Thin-section CT showed variable shaped subpleural nodules in all five cases. The size of nodules were 1-5mm in two cases(40%) and 5-10mm(60% ) in three cases. Feeding vessel signs were seen in two cases. Other findings were atelectasis in three cases, cardiomegaly in three cases, ground-glass opacity and interlobular septal thickenings by pulmonary edema in two cases. CONCLUSION: Plain chest radiographic findings of hematogenous candida pneumonia in major burn patients are randomly distributed nodules or consolidations of variable size. Thin-section CT findings are variable shaped subpleural nodules less than 1 cm.

Purpose: Here, we report a case of a fungal corneal ulcer caused by Talaromyces allahabadensis (T. allahabadensis).Case summary: A 69-year-old male was admitted to our hospital with pain and hyperemia in his left eye after 2 months of treatmentat a local clinic for herpetic keratitis. The patient had a previous history of trauma to his left eye caused by a persimmon treebranch. He had a peripheral epithelial defect, stromal infiltration, and severe corneal edema in his left eye. Gram staining, a KOHsmear, and a culture were performed using corneal specimens; the results were all negative. With the assumption of herpetickeratitis, antiviral and empirical antibiotic treatments were started. After 2 weeks, the stromal infiltrations on his left eye increased,so we again conducted staining and culture studies. T. allahabadensis was isolated from a specimen, so treatment wasstarted using antifungal agents, and a conjunctival flap graft was performed due to the risk of a corneal perforation. Conclusions A case of corneal ulcer caused by T. allahabadensis in a patient with posttraumatic herpetic keratitis was successfullytreated with antifungal agents and conjunctival flap surgery.

PURPOSE: To analyze the effect of the growth control on human breast cancer cells with genistein treatment and to investigate the mechanism of genistein-induced G2/M arrest in T47D and MDA-MB231 breast carcinoma cells by Cdc25C expression. METHODS: We analysed the proliferartion of the two cell lines by using MTT proliferation assay, flow cytometric analysis, real-time quantitative RT-PCR and western blotting and investigated the effect of genistein on cell survival, cellular toxicity, cell cycle progression-related genes and their mRNA and protein alterations. RESULTS: The DNA flow cytometric analysis of both cell lines treated with genistein showed a dose-dependent growth inhibition and accumulation in the G2/M phase of cell cycle. The expression of p21 mRNA and protein increased in both cell lines following genistein treatment but p27 expression was unchanged. Furthermore, decreased Cdc25C expression with decreased polo-like kinase (PLK) 1 expression and increased PLK3 expression were observed after genistein treatment. The decreased level of Cdc25C in the nucleus was associated with decreased phosphorylation of Cdc25C by PLK1. The expression of PLK3 was increased with a dose-dependent and a time-dependent manner and was associated with decreased Cdc25C expression. Check point kinase (CHK) 1 and CHK2 revealed different expression patterns each other. The CHK1 expression was independent of the presence of genestein. CHK2 expression increased in MDA-MB231 cells associated with decreased Cdc25C expression but not in T47D. CONCLUSION: These results suggest that genistein induces a G2/M arrest in human breast cancer cells, the mechanism of which is due, in part, to decreased in Cdc25C phosphatase by a regulatory effect of PLK1, PLK3, and CHK2 as well as increased expression of the cyclin dependent kinase inhibitor p21(WAF1/CIP1).

Purpose: We investigated the serial culture of multiuse eye drops applied by medical personnel by intentionally touching the tip of the bottle. Methods: Ten different unpreserved and preserved eye drops including eye drops for allergies, artificial tears, antibiotics, and corticosteroids were included. One bottle was stored at room temperature and the other bottle stored under refrigeration. The experimenter intentionally touched the tip of the bottle with a finger twice daily. The first culture test was performed 2 weeks after contamination and the culture were performed six times; 2 weeks apart. Results: Contamination was noted in three types of eye drops (artificial tears without preservatives, corticosteroids, and anti-allergic eye drops) under refrigerated conditions and four types of eye drops (artificial tears without preservatives, artificial tears with preservatives, corticosteroids, and anti-allergic eye drops) under room temperature conditions. The contamination in 13 eye drops was attributable to five microbial species: Staphylococcus epidermidis (m/c), Staphylococcus hominis, Rhodotorula sp., Corynebacterium sp., and Bacillus sp. Under refrigerated conditions, three eyedrop bottles were contaminated, with five positive cultures in 12 weeks. However, at room temperature, four eye drop bottles were contaminated with eight positive cultures. The culture results changed according to culture time. In some cases, the same result was obtained 2 weeks after the first positive culture but in other cases the result was negative or one of two strains disappeared. Conclusions Eye drops can be contaminated under both room temperature and refrigerated conditions. We should consider serial culture for eye drops because the culture results could be variable according to time.

Six cases of nasal septum perforation were found among welders during periodic physical checkup in 1997. Considering the size, shape and margin, the perforations were assumed to have been occurred several years before of which the diameter were 8~15 mm. To investigate the cause of perforation, we reviewed the past history of preemployment, the results of annual working environment survey and the material safety data sheets of welding rods and steels with which they have dealt, and analyzed the concentration of several metals of welding fume and the concentration of blood and urinary chromium. In the result, we presupposed that the nasal septum perforations of welders were due to chronic exposure to low level hexavalent chromium and/or nickel, and report these cases with literatures review.
