Miliary osteoma cutis of the face is a form of primary osteoma cutis. We report a case of miliary osteoma cutis on the jaw of a 55-year-old female. She presented with several 2~3 mm sized, skin-colored firm papules over both lower jaws for 5 years. Skin biopsy was performed and the specimen showed numerous osteocytes and osteoblasts in the bony tissue which was located in the deep dermis.

PURPOSE: This study was performed to evaluate the impact of microvessel density (MVD), a reflection of tumor angiogenesis, and microvascular invasion (MVI) on the prognosis of patients with renal cell carcinoma (RCC). MATERIALS AND METHODS: Formalin-fixed, paraffin-embedded tissue sections of RCC from 81 patients who had undergone radical nephrectomy were stained immunohistochemically for CD34, which decorate endothelial cells, in order to assess MVD and MVI. The immunostaining results of MVD and MVI were compared with the clinicopathological variables. RESULTS: Twenty-two patients had either synchronous or metachronous metastases and fourteen patients died during the follow-up. MVD was significantly correlated with only metastasis (synchronous or metachronous; p=0.020). MVI was significantly correlated with tumor size (p=0.005), TNM stage (p<0.001), T stage (p<0.001), M stage (p=0.001), and metastasis (synchronous or metachronous; p=0.007). MVD was not significantly associated with MVI (p=0.232). The survival rate of patients with higher MVD or MVI-positive tumors was significantly lower than that of patients with lower MVD or MVI-negative tumors, respectively (p<0.0001, p=0.0002). Multivariate analyses indicated that tumor size, M stage and MVI were independent prognostic factors for cancer-specific survival. MVD was not an independent factor. CONCLUSIONS: MVD and MVI were associated with metastasis and a worse prognosis in RCC, which suggests that tumor angiogenesis and MVI may play an important role in the progression of RCC. MVI was an independent prognostic factor for cancer-specific survival.

Submucosal infiltration and the topical application of epinephrine as a vasoconstrictor produce excellent hemostasis during surgery. The hemodynamic effects of epinephrine have been documented in numerous studies. However, its metabolic effects (especially during surgery) have been seldom recognized clinically. We report two cases of significant metabolic effects (including lactic acidosis and hyperglycemia) as well as hemodynamic effects in healthy patients undergoing orthognathic surgery with general anesthesia. Epinephrine can induce glycolysis and pyruvate generation, which result in lactic acidosis, via β2-adrenergic receptors. Therefore, careful perioperative observation for changes in plasma lactate and glucose levels along with intensive monitoring of vital signs should be carried out when epinephrine is excessively used as a vasoconstrictor during surgery.

BACKGROUND: Endothelial dysfunction is suggested to be one of the pathogenesis of cerebral white matter lesion (cWML). Vascular endothelial growth factor (VEGF) plays a crucial role in angiogenesis and integrity of vascular endothelial cell, and altered expression of VEGF gene induces vascular diseases including cerebrovascular diseases. The objective of this study is to investigate whether single nucleotide polymorphism (SNP) of VEGF gene confers an increased risk of cWML. METHODS: Total 337 study subjects without history of stroke were included. The presence and severity of cWML were measured on fluid-attenuated inversion recovery image. Genotypes of VEGF -2578G>A, -1154G>A, -634G>C and +936C>T were analyzed. RESULTS: Among 337 study subjects, cWML was found in 208 patients (62%), and fifty-eight cases (17%) of them had overt cWML. In univariate analysis, age, female sex and plasma total homocysteine level (tHcyt) were higher in the mild and overt cWML group than no cWML group (p<0.05). The percentage of previous history of hypertension and the value of systolic blood pressure were higher in overt cWML group than no cWML group. In univariate and logistic regression analysis, none of four tested VEGF SNPs was significantly different between control group, mild and overt cWML groups. There was no difference between plasma tHcyt levels and each VEGF SNPs in control group and cWML groups. CONCLUSIONS: In this study, old age, female sex, hypertension and plasma tHcyt were associated with cWML. However, we failed to find an association between cWML and VEGF gene polymorphism, which may indicate that genetic polymorphism of VEGF does not play a direct role in the pathogenesis of cWML.

Systemic amyloidosis after gastric cancer surgery is a very rare phenomenon. Less than ten such cases have been reported in the international literature. Although systemic amyloidosis has been reported to be associated with lymphoma, multiple myeloma, and renal cell carcinoma, its association with gastric cancer remains unclear. We report a case of a 64-year-old male who developed systemic amyloidosis 24 months after a Billroth-I gastrectomy for gastric cancer, and provide a brief review of the literature.

The serotonin 6(5-HT6) receptor gene is a candidate gene for influencing the clinical response to treatment with antidepressants. The purpose of this study was to determine the relationship between the C267T polymorphism in the 5-HT6 receptor gene and the treatment response to citalopram in a Korean population with major depressive disorder(MDD). METHODS: Citalopram was administered for 8 weeks to the 90 patients who completed study. 21-item Hamilton depression rating scale(HAMD-21) was used as a outcome measure. RESULTS: We found that the genotype, allele, and allele-carrier distributions did not differ significantly between MDD patients and normal controls. A main effect of an interaction of genotype with time on the decrease in the HAMD-21 score during the 8 weeks study period was not found. ANOVA revealed no significant effects of the C825T polymorphism on the decrease in the HAMD-21 score at each time period. CONCLUSIONS: These results suggest that the C267T polymorphism in the 5-HT6 receptor gene is not associated with the treatment response to citalopram.
