PURPOSE: We report a case of unilateral, focal, pigmented paravenous retinochoroidal atrophy (PPRCA). CASE SUMMARY: A 46-year-old female visited our clinic in complaint of a vague problem with her right eye identified during a general medical examination. The visual acuity (without correction) of both eyes was 1.0. Slit-lamp examination of both eyes revealed no specific signs. Fundus examination of the right eye revealed focal, bony-spicule-shaped retinochoroidal atrophy with pigmentation along the course of the superior retinal vein. A fundus autofluorescence examination revealed principally hypofluorescence with some hyperfluorescence at the margin of the atrophic retinochoroidal lesion. Optical coherence tomography revealed mixed clumping and atrophy of the retinal pigment epithelium (RPE) layer and thinning of the choriocapillaris layer. Fluorescence angiography revealed a window defect and blockage at the site of the lesion (the fluorescent material did not enter the lesion). The site of the window defect was in correlation with the atrophic RPE region. The site of the blockage at lesion also matched with the site of the regional pigment clumping. No definite leakage was observed. CONCLUSIONS: To the best of our knowledge, this is the first case of unilateral focal PPRCA reported from Korea.

A previously healthy 44-year-old woman who was diagnosed as having dermatomyositis suddenly developed severe dyspnea while being in the state of improved condition of muscle weakness. Interstitial lung disease was found on high resolution computed tomography (HRCT). In spite of the treatment with the immune-modulating agent (high dose steroid, cyclophosphamide, immunoglubulin and cyclosporine), her condition deteriorated further and rapidly, leading to death. More intensive agent such as FK506 would be necessary in those cases of dermatomyositis-related interstitial lung disease that have poor prognostic factors.

The p53 gene, which resides on the short arm of chromosome 17, has been described as a tumor suppressor gene playing a role of G1 checkpoint monitering DNA damage, but mutation of this gene has been shown in numerous types of human cancers. The nm23-H1 gene encodes human NDP(nucleotide diphosphate) kinase. The expression of nm23-H1 gene was postulated to inversely correlate with metastatic potential of malignant tumors. We examined immunohistochemical expression in 30 cases of stomach cancers including 10 cases each of early gastric cancers(EGC), advanced gastric cancers without lymph node involvement, and advanced gastric cancers with lymph node involvement, which were stained with mouse monoclonal antibody of p53(PB53-12) and nm23-H1. Positive nuclear staining of p53 was frequently found in advanced gastric cancers with lymph node involvement (80%). The lymph node positive group showed high expression of p53(80%), and low expression of nm23-Hl(30%) than lymph node negative group. There was no significant correlation of p53 and nm23-H1 expression with tumor size, invasion depth, TNM stages, distant metastasis and histologic differentiation. Based on the present study, the expression of p53 and down regulation of nm23-H1 are thought to be correlated with tumor progression and lymph node involvement, and may be a useful prognostic factor in gastric cancers.

Leptin, which is a plasma protein produced by the obese gene, is expressed and secreted by adipocytes. The clearance of lepdn from the circulation is unknown. But, markedly elevated serum leptin concentrations have recently been reported in patients with chronic renal failure. The purpose of the present study was to investigate plasma leptin concentration of patients with chronic renal failure and evaluate the factors affecting plasma leptin levels. Plasma leptin, insulin, and body mass index were determined in 34 patients with chronic renal failure and 55 control subjects. The plasrna leptin concentrations were not significantly different between patients with chronic renal failure and control subjects (9.4+/-11.8 vs 4.9+/-4.2ng/ml, P>0.05). The serum leptin concentrations were not significantly higher in both male and female CRF patients compared with control subjects (3.96+/-5.72 vs 2.48+/-1.65, P=0.1947, 17.07+/-14.02 vs 7.49+/-4.63ng/ml, P=0.07, respectively). And, there was no significant correlation between serum creatinine and plasma leptin. However, there was significant correlation between plasma leptin concentration and insulin level (P<0.05). We fit a multiple linear regre- ssion analysis with plasma leptin level as the dependent variable in CRF. Sex (male vs female) (P< 0.001) and insulin (P=0.004) were independently associated with plasma leptin level in CRF. These results suggested that plasma leptin level was regulated or affected by multiple factors inclu- ding sex and insulin resistance. Additional study is required to evaluate relationship between plasma leptin and insulin resistance in chronic renal failure.

About 5% of burn patients come with other injuries. When patients with multiple rib fractures are put under general anesthesia, there is a higher rate of a variety of complications, such as hemothorax, pneumothorax, lung contusion, and etc. Also, symptoms of the complications are likely to get worse. Therefore, it is important to decide when it is appropriate to perform surgery. Our hospital delayed operation time on two burn patients who had multiple rib fractures and then performed surgery under general anesthesia, treating patients without any particular complications.

A few cases of laparoscopic surgery for urachal remnant in children has been reported in English literature. With recent developments in minimal invasive surgery, laparoscopic approach for urachal remnant in adulthood is recommended by some laparoscopic surgeons because of its technical feasibility and safety as well as cosmesis. Recently we experienced a case of complicated urachal remnant in a 14-month-old girl, who was managed by laparoscopic approach. At presentation, she complained of high fever and lower urinary tract symptoms. After 6 weeks of antibiotics therapy, laparoscopic surgery was performed transperitoneally via 3 ports. Our experience suggests that laparoscopic excision of urachal remnant can be performed easily and safely in children.

BACKGROUND AND OBJECTIVES: Chronic obstructive pulmonary disease (COPD) is known to induce chronic rhinosinusitis (CRS). Nasal polyp, which is frequently found in patients with CRS, seems to have close relationship with COPD, but little is known about its relationship with COPD. In this study, we investigated the relationship between COPD and nasal polyp in middle aged and elderly CRS patients. SUBJECTS AND METHOD: We analyzed the clinical data of 174 patients (age of over 50 years) with CRS. Patients were divided as COPD [forced expiratory volume (FEV1)/forced vital capacity (FVC)<70%, n=30] and non-COPD group (FEV1/FVC≥70%, n=144) according to the pulmonary function test results. Binary logistic regression analysis was used to describe the relationships between clinically relevant factors related to nasal polyp. RESULTS: On logistic regression analysis, no significant relationship was found between age [adjusted odds ratio (AOR): 1.058, 95% confidence interval for the difference (CI)=0.995-1.126, p=0.073], sex AOR: 0.897, 95% CI=0.366-2.415, p=0.897), smoking (AOR: 0.434, 95% CI=0.154-1.219, p=0.113) and obesity (underweight AOR: 3.833, 95% CI=0.781-18.808, p=0.098, overweight AOR: 5.169, 95% CI=0.996-26.814, p=0.051, obese AOR: 2.911, 95% CI=0.335-25.329, p=0.333) with polyp. However, there was a negative correlation between COPD history and nasal polyp with statistical significance (AOR: 0.288, 95% CI=0.102-0.809, p=0.018). CONCLUSION: Our findings suggest that patients with COPD are less likely to have nasal polyp than patients without COPD.
