Sebaceous adenoma is a rare solitary or multiple yellow, circumscribed neoplasm consisting of sharply demarcated, proliferating lobules or irregular size and shape that are composed of three cell bypes: basal cells, mature and transitional sebaceous cells. We reported a case of extremely rare sebaceous adenoma arising in caruncle of the left eye in a 78-year-old female. A polypoid tumor nodule, measuring 0.6x0.5 cm, was noticed 6 months before resection. It was grayish white with granular surface. There is no evidence of associated visceral neoplasm. Histopathologically, it revealed a lobulated tumor, composed of equal amount of highly differentiated sebaceous and intermediate transitional epithelium with minor participation of basaloid cells. This tumor is thought to be the neoplasm of the sebaceous gland normaly present in the caruncle of the eye rather than ectopic origin.

Subcutaneous granuloma annulare (SGA) is a rare, benign noninfectious histiocytic disease of unknown cause, characterized by necrobiosis of the connective tissue surrounded by infiltrates of histiocytes and lymphocytes. We report a case of SGA in a 49/12-year-old boy. The lesions were five nontender subcutaneous nodules in the parieto-occipital scalp, measuring 1.0 cm to 2.0 cm in diameter. Microscopical examination revealed variable stages of multiple necrobiotic areas, which showed central necrobiosis with palisading histiocytes, involving both the lower dermis and subcutaneous fatty tissue. Electron microscopic findings revealed many histiocytes in the necrobiotic areas with degenerating and necrotic collagen fibers as well as regenerating fibroblasts.

The clinical application of the three-dimensional radiographic technique had been limited to standard Broadbent-Bolton cephalometer with biplanar stereoradiography. We developed a new method for compensating the error of head position in ordinary non-biplanar cephalostat. It became to possible to use the three dimensional cephalogram commonly in clinical bases. 1. The method of methemetical compensation of head positioning error in non-biplanar condition was evaluated with dry skull. The error of the method of first and the second trial was 0.46+/-1.21, 0.33+/-0.90mm, which means the error of the head positioning correction in conventional cephalogram was within clinical acceptance. 2. The reproducibility of this system for clinical application was 0.54 mm (-2.99~2.26mm) which defines the absolute mean difference of the first and second trial. Compare to the The landmark identification error 1.2+/-1.6mm, the error of the measurement was within the range of landmark identification error. The result indicates the adequate clinical accuracy of the computation of three-dimensional coordinates by compensation of the error of the head position in ordinary non-biplanar cephalostat.

We experienced 3 cases of Candida esophagitis in infancy which were diagnosed by esophageal endoscopy. First case, 10 month-old boy with combined immune deficiency had suffered from oral thrush and poor feeding for more than 4 months. Esophageal endoscopy revealed multiple whitish creamy patches on the friable erythematous and necrotic mucosa of the esophagus. He was firstly treated with amphotericin-B but in vain. Then he was treated with fluconazole (5 mg/kg/day) and in a few days oral thrush nearly disappeared and endoscopy after 2 weeks revealed complete healing of the esophagitis. Second case, 6 month-old boy with some cellular immue defect also suffered from oral thrush, poor feeding and intermittent fever. He was treated with fluconazole and oral thrush was imporved. He was discharged without follow up endoscopy. Third case, 4 month-old girl with liver cirrhosis due to infantile cholestasis had Candida sepsis. Esophagitis was found incidentally during the endoscopic examination of esophageal varix. First 2 cases showed multiple small filling defects and decreased motility on esophagography. Candida antigen was not detected in the sera of all 3 cases of candidiasis. We conclude that Candidia esophagitis should be suspected when an infant has been suffering from long-term treatmet-resistant oral thrush and poor feeding and that esophageal endoscopy can be easily performed in infants also and useful in diagnosing esophagitis and assessing the outcome of treatment.

BACKGROUND/AIMS: Nucleotide-binding oligomerization domain 1 (NOD1) is required for primary intestinal epithelial cells (IECs) to respond to natural mucopeptides secreted by gram-negative bacteria. Infection of human IECs with invasive bacteria up-regulates intercellular adhesion molecule-1 (ICAM-1) expression. However, the role of NOD family members in host defense has been largely unknown. The aim of this study was to determine whether there is a functional role for NOD1 in the up-regulation of ICAM-1 expression in invasive bacteria-infected IECs. METHODS: ICAM-1 mRNA expression was compared between controls, Caco-2 or HT29 cells transfected with an empty vector, and IECs stably transfected with a dominant-negative (DN) NOD1. Expression was compared using qualitative reverse transcription polymerase chain reaction (RT-PCR), real-time RT-PCR, and flow cytometry after infection with enteroinvasive Escherichia coli O29:NM or Shigella flexneri. Nuclear factor kB (NF-κB) activation was determined by electrophoretic mobility shift assays. RESULTS: DN NOD1 significantly inhibited the up-regulation of ICAM-1 expression in response to an enteroinvasive bacterial infection. The Caco-2 cells transfected with DN NOD1 manifested marked inhibition of NF-kB activation in response to E. coli O29:NM infection. CONCLUSIONS Signaling through NOD1 may play an essential role in neutrophil trafficking following infection with enteroinvasive bacteria.

Hepatitis B virus(HBV) infection has been suggested as the etiologic agent in membranoproliferative glomerulonephritis(MPGN), but the mechanism by which HBV infection leads to MPGN in human has not been established. To localize the HBV antigen and HBV-DNA in the kidney tissue, we examined paraffin sections of kidney biopsies which were positive for HBsAg by immunohistochemical study from 13 HBV carriers with MPGN (HBV-MPGN). Polymerase chain reaction(PCR) and in situ PCR(ISP) were used for the HBV DNA amplification and localization in kidney tissues. Primers used in PCR and ISP were from the S, C, and X HBV-DNA regions. Immunohistochemical study showed HBsAg deposits on the mesangium and glomerular capillaries. Arteriolar deposits were also occasionally observed. PCR for the S, C, and X regions were positive in 11 patients(85%), 11 patients(85%), and 9 patients (69%), respectively. The PCR findings were further confirmed by direct sequencing of PCR products and the amplification of HSP70 gene as a control. ISP showed the amplified HBV-DNA at the glomeruli and renal tubules. For S region, ISP was positive in 7 patients. For C and X regions, ISP was positive in 8 patients, respectively. 5 patients showed the positive signals for both the glomeruli and tubules, while 4 patients were positive at the tubules only. These 4 patients seemed to have the longer disease durations when compared to the other 5 patients (52.8 months vs. 11.8 months), but it was not statistically significant. In conclusion, the detection and the localization of HBV antigen and DNA in renal tissues indicate the presence of the complete virion in the kidney. These results suggest that HBV may infect the kidneys of HBV carriers with MPGN.

Complement-mediated neutrophil activation has been hypothesized to be an important mechanism of reperfusion injury. It has been proposed that C1 esterase inhibitor (C1 INH) may prevent the complement-dependent activation of polymorphonuclear leukocytes (PMNs) that occurs within postischemic myocardium. Therefore, The effect of C1 INH was examined in neutrophil dependent isolated perfused rat heart model of ischemia (I) (20 min) and reperfusion (R) (45 min). Administration of C1 INH (5 mg/Kg) to I/R hearts in the presence of PMNs (100 X 106) and homologous plasma improved coronary flow and preserved cardiac contractile function (p<0.001) in comparison to those I/R hearts receiving only vehicle. In addition, C1 INH significantly (p<0.001) reduced PMN accumulation in the ischemic myocardium as evidenced by an attenuation in myeloperoxidase activity. These findings demonstrate the C1 INH is a potent and effective cardioprotective agent inhibits leukocyte-endothelial interaction and preserves cardiac contractile function and coronary perfusion following myocardial ischemia and reperfusion.

In the field of the forensic medicine, deciding the cause of the injury is very important. Forensic doctors usually use their naked eyes, two dimensional photos, the characteristics and the distribution of the wounds for evaluating the cause of the injuries. After body release, forensic doctors not infrequently met the questions from the law enforcement whether the injuries were matched with the new facts or statements given through the progression of the investigation. In the face of answering this question, the information or evidence about the injury is insufficient. New technologies and instruments are being developed and will be helpful for getting the evidence from the human skin injuries. In this preliminary study, authors try to find the usefulness of appraisal techniques(3D scanner, trace evidence, TMDT, alternative light) that are already used for other purposes in forensic field. These techniques have their own merits for preserving the evidences from the injured skin. But further studies and systemic approaches are essential for more scientifically verified evaluation of the cause of the skin injury.
