We have expierenced a rare case of coloboma of the lower lid combined with epidermoid ine lusion cyst. We removed the epidermoid inclusion cyst and repaired the coloboma with ocr a new techniqe using a triangular flap and achieved satisfactory result. We reviewed the literatures and discused this rare case.

BACKGROUND: Cell lines can be established when the cells are clonally selected and propagated continuously in vitro culture system. Recently we established a B cell line (KEB1) from the bone marrow cells of the patient infected with Epstein-Barr virus (EBV). METHODS: The patient's initial platelet count was 1,000/microliter and peripheral blood smear showed atypical lymphocytes accounting 20% of the differentials of WBC. Antibodies to EBV and PCR for EBV were positive but heterophil antibody was negative. Mononuclear cells were obtained by Ficoll-paque separation and suspended in RPMI media with 10% FCS. After incubation in 37degrees C, 5% CO2 incubator, cells grew continuously and finally immortalized to B cell line. RESULTS: Cells showed abundant, clear basophilic cytoplasms and a few vacuoles. Cells had granular reaction in PAS stain and were positive to B cell antibodies. Immunohistochemical stain showed positive expression for EBV antibody. Electron microscopic finding of cultured cells showed several viral particles, and immunoelectron microscopic finding showed electron dense expression. Immunophenotyping of cultured cells was positive for B lymphoid lineage, and karyotypings had hypotetraploidy. Cells expressed MAGE and SSX gene. Cytotoxicity showed relative resistance to mistletoe and several chemotherapeutic agents compared to leukemic cell line. CONCLUSION: KEB1 cell line was established from the bone marrow cells of the patient with infectious mononucleosis. The characteristics of the cell lines including morphology, immunophenotype, karyotype, gene analysis (MAGE, SSX) and chemosensitivity were analyzed. There should be further studies of these cell lines including gene analysis, telomerase activity and cytokine production. This cell line might be helpful to establish another normal lymphocyte cell line and to predict the toxicity of chemotherapy.

OBJECTIVES:
Proteinuria is widely used to predict cardiovascular risk. However, there is insufficient evidence to predict how changes in proteinuria may affect the incidence of cardiovascular disease.
METHODS:
The study included 265,236 Korean adults who underwent health checkups in 2003-2004 and 2007-2008. They were categorized into 4 groups based on changes in proteinuria (negative: negative → negative; resolved: proteinuria ≥1+ → negative; incident: negative → proteinuria ≥1+; persistent: proteinuria ≥1+ → proteinuria ≥1+). We conducted 6 years of follow-up to identify the risks of developing ischemic heart disease (IHD), acute myocardial infarction (AMI), and angina pectoris according to changes in proteinuria. A multivariate Cox proportional-hazards model was used to calculate adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) for incident IHD, AMI, and angina pectoris.
RESULTS:
The IHD risk (expressed as HR [95% CI]) was the highest for persistent proteinuria, followed in descending order by incident and resolved proteinuria, compared with negative proteinuria (negative: reference, resolved: 1.211 [95% CI, 1.104 to 1.329], incident: 1.288 [95% CI, 1.184 to 1.400], and persistent: 1.578 [95% CI, 1.324 to 1.881]). The same pattern was associated with AMI (negative: reference, resolved: 1.401 [95% CI, 1.048 to 1.872], incident: 1.606 [95% CI, 1.268 to 2.035], and persistent: 2.069 [95% CI, 1.281 to 3.342]) and angina pectoris (negative: reference, resolved: 1.184 [95% CI, 1.065 to 1.316], incident: 1.275 [95% CI, 1.160 to 1.401], and persistent: 1.554 [95% CI, 1.272 to 1.899]).
CONCLUSIONS
Experiencing proteinuria increased the risks of IHD, AMI, and angina pectoris even after proteinuria resolved.

Objective:
Mood disorder and borderline personality pathology (BPP) are frequently comorbid and relate to childhood trauma. We investigated the relationship between childhood trauma and BPP features in mood disorder patients versus controls.
Methods:
A total of 488 mood disorder patients, particularly major depressive disorder (MDD), bipolar I disorder (BD I), and bipolar II disorder (BD II), and 734 controls were included. We examined between-group BPP-related differences and correlated between BPP and childhood trauma using the Childhood Trauma Questionnaire-Short Form (CTQ) and the Personality Assessment Inventory–Borderline Features Scale.
Results:
BD II patients showed significantly higher BPP. Emotional abuse and neglect were prominently associated with BPP, while affective instability and negative relationships exhibited a stronger association with childhood trauma. We also found a positive relationship between childhood trauma and BPP in MDD, BD I, and BD II patients.
Conclusion
The findings of the present study imply that BPP features are more likely to be found in patients with BD II than BD I or MDD. Mood disorder patients with severe childhood trauma may have higher BPP features. Thus, further study of the relationship between childhood trauma and BPP features could improve the therapeutic approaches and help understand patients with mood disorders.
