Romberg syndrome is a rare disease and characterized by unilaeril atrophy of the skin, subcutaneous tissue and the underlying structure of half the face. The lesion does not usually cross the midline of the scalp. Roriberg syndrome is sometimes mildsnosed as linear scleroderma, although they differ widely in their clinical and histological apperance. A 13-year-old boy was present with a one year history of idefined atrophic patch on the left side of face and neck. We involved skin was not bound down to the underlying structure. The history revealed no prcvious trauma or disease, He had no abnormal neurologic finding. Computerized tomography demonstrated a diminished subcutaneouat volume and also decreased thickness of back muscle is the left side face from cheek to neck.

BACKGROUND: The aim of this study was to compare the cardiovascular changes followed by laryngoscopy with the McCoy laryngoscope blade with those followed by laryngoscopy with the Macintosh laryngoscope blade. METHODS: Forty eight patients were randomly divided into two groups. Following induction with fentanyl 2 mcg/kg and thiopental 5 mg/kg, and muscle relaxation with vecuronium 0.1 mg/kg, the vocal cords were visualized with either the McCoy or the Macintosh laryngoscope blade, then tracheal intubation was performed. Heart rate and arterial blood pressure were measured just before and after laryngoscopy, and 1, 3 and 5 min later. RESULTS: There was a significant increase in both heart rate and arterial blood pressure after tracheal intubation using the Macintosh laryngoscope. Also, use of the McCoy blade resulted in a significant increase in both heart rate and arterial blood pressure. CONCLUSIONS: There was no significant difference on arterial pressure and heart rate to laryngoscopy and tracheal intubation with either the McCoy blade or the Macintosh.

Candidiasis is the most common fungal infection complicating the course of patients with hematologic malignant neoplasms. Although widespread organ involvement is characteristic of disseminated candidiasis, reports of skin are rare. Reports describing typical clinical and histopathological finding of cutaneous lesions are very important since it may enable a diagnosis of disseminated candidiasis to be made and thus antifungal therapy can be initiated earlier. A 50-year-old housewife was admitted with a 5-month history of fatigue and easy bruising. She was diagnosed as ha.ving acute myelocytic leukemia and treatment was begun with daunorubicin and cytosin, arabinoside. Eight days after the start of chemotherapy, she developed a fever and generalized tender well demacated erythematous to purplish papulonodular eruption. A biopsy specimen from the skin lesion showed perivascular mononuclear cell infiltration and spore and pseudohypae v,rere found within the dermis and subcutis in PAS stain. Cultures of one skin biopsy specimen and one of four blood sarnples grew Candida tropicalis. The patient was treated with intravenous amphotericin B for disseminated candidiasis. On the tenth day of antifun gal therapy, she developed cardiopulmonary arrest and died.

Purpose: To assess the impact of toxoplasma immunoglobulin G (IgG) titers on the diagnosis of active ocular toxoplasmosis. Methods: We retrospectively analyzed the medical records of patients tested for toxoplasma IgG at our uveitis clinic. Active ocular toxoplasmosis was clinically diagnosed based on wide-angle fundus photography and disease progression. Patients with IgG titers ≥ 30 IU/mL were classified as seropositive-high titer, those with IgG titers of 1.6-30 IU/mL as seropositive-low titer, and the remaining patients as seronegative. We compared the proportion of active ocular toxoplasmosis among these groups. Additionally, we evaluated the sensitivity and specificity of each titer and attempted to determine an ideal reference titer for toxoplasma IgG in diagnosing active ocular toxoplasmosis. Results: Out of 824 patients, 86 (10.4%), 88 (10.7%), and 650 (78.9%) were categorized as seropositive-high titer, seropositivelow titer, and seronegative, respectively. Among these patients, 34 in the seropositive-high titer group and 2 in the seropositive- low titer group were clinically diagnosed with active ocular toxoplasmosis. The false-positive rate was significantly different between the groups, being 60.5% in the seropositive-high titer group and 97.7% in the seropositive-low titer group (p < 0.001). The receiver operating characteristic curve indicated that 37.70 IU/mL could be an ideal reference titer for diagnosing ocular toxoplasmosis. Conclusions The false-positive rate was notably lower (60.5%) in patients with IgG titers ≥ 30 IU/mL compared to those with titers of 1.6-30 IU/mL (97.7%). Therefore, not only the presence of IgG but also the level of titer appears to be important in diagnosing ocular toxoplasmosis.

PURPOSE: iNOS expression in vascular smooth muscle cells (VSMC) causes the development of septic shock, and multiple organ dysfunction syndrome (MODS). For the inhibition of iNOS expression, glucocorticoids are known to inhibit iNOS expression but immunosuppression decreases its clinical availability. Recently, aspirin was reported to inhibit iNOS expression, but the mechanism and effectiveness are still unclear. In this investigation, on aspirin, several non steroidal antiinflammatory drugs (NSAIDs) were applied to clarify the inhibitory mechanism of iNOS expression and NO production in lipopolysaccharide (LPS) treated VSMCs. METHOD: VSMCs were primarily cultured from rat aorta and confirmed by immunocytochemistry of anti-smooth muscle myosin antibody. LPS, an inducer of iNOS, and NSAIDs, such as aspirin, indomethacin, ketoprofen sodium salicylate and acetaminophen were used. The concentrations of nitrite in culture media following the addition of LPS with a 1-hour pretreatment of NSAIDs were measured by spectrophotometry with griess reaction. Western blot and RT-PCR for iNOS protein and iNOS mRNA, respectively, were performed. RESULT: Acetaminophen had no effect on the inhibition of nitrite production. NSAIDs, especially ketoprofen and sodium salicylate, showed a significant inhibitory effect on nitrite production. In their mechanism, all the NSAIDs in present study inhibited iNOS mRNA and protein expression. CONCLUSION: These results suggest that the inhibitory mechanism on iNOS expression of NSAIDs is due to the inhibition of iNOS mRNA expression and subsequent inhibition of iNOS protein expression.

PURPOSE: Peroxisome proliferator-activated receptor gamma (PPARgamma) has become a potential target for the prevention and treatment of human cancers. PPARgamma ligands inhibit cell proliferation of estrogen receptoralpha(ERalpha)-positive breast cancer cells. However, it has recently been shown that ERalpha-negatively inhibits PPARgamma signaling in breast cancer cells, indicating that PPARgamma ligand may be more useful for treating ERalpha-negative breast cancer cells compared to ERalpha-positive breast cancer cells. In this study, we attempted to elucidate the role of PPARg in ERalpha-negative breast cancer cells. METHODS: The effect of PPARgamma ligand on the growth of MDA-MB-231 cells was measured by MTT assay and flow cytometric analysis. TUNEL staining and Hoechst 33342 fluorescent staining were used to observe the effects of PPARgamma ligand on cell apoptosis. The regulatory proteins of the cell cycle were measured by Western blot. RESULTS: The treatment of MDA-MB-231 human breast cancer cells with the PPARgamma ligand, trgoglitazone, was shown to induce inhibition of cell growth in a dose-dependent manner. Cell cycle analysis showed a G1 arrest in MDA-MB-231 cells exposed to troglitazone. The apoptotic effect by troglitazone demonstrated that apoptotic cells were elevated from 2.5-fold of the control level at 10 mM, to 3.1-fold at 50micrometer and to 3.5-fold at 75 mM of troglitazone. Moreover, troglitazone treatment dose-dependently caused a marked decrease in the pRb, cyclin D1, cyclin D2, cyclin D3, cdk2, Cdk4 and Cdk6 expressions and there was a significant increase in the p21 and p27 expressions. CONCLUSION: These results indicate that trgoglitazone induces cell-cycle G1 arrest and apoptosis in ERalpha-negative MDA-MB-231 breast cancer cells. Collectively, this paper shows that PPARgamma ligand is an important player as a member of the chemotherapeutic candidates for treating ERalpha-negative breast cancer.

OBJECTIVES: Many recent studies of relationship between geriatric depression and changes in brain have examined the structural abnormalities in hippocampus. Using MRI, the hippocampal volumes of patients with major depression were measured and compared with control subjects for research of above relationship. METHOD: Fourteen patients (early-onset five, late-onset nine) with major depressive disorder based on DSM-IV and fourteen age-matched normal controls are included. Applying semiautomated computer program to MRI, we measured and compared the hippocampal volumes in two groups. Moreover we identified the laterality and the correlation of the volumes with age of onset, duration of education, numbers of psychiatric admission, duration of illness, MMSE scores at admission, and severity of depression. RESULT: No significant difference was observed between the hippocampal volumes of patients with major depressive disorder and those of control subjects. A significant correlation in patients was observed between duration of illness and left hippocampal volume to cerebral volume ratio. In early-onset depressed patients, left hippocampal volume was larger than in late-onset depressed patients and the positive correlation was observed between MMSE scores at admission and left hippocampal volume to cerebral volume ratio. In late-onset depressed patients, there was the negative correlation between numbers of psychiatric admission and MMSE scores at admission as well as and between cerebral volume and age of onset. CONCLUSION: Our study indicated no change in the volume of hippocampus among geriatric major depressive patients. So we suggest that more extensive and systematic studies for structural abnormality of hippocampus will be required.

PURPOSE: The selection of systemic therapy for breast cancer is based on the expression pattern of biological prognostic markers. Neoadjuvant chemotherapy has been considered the standard care for locally advanced breast cancer. However, its effect on the expression of biological prognostic markers is controversial. The aim of this study was to determine whether neoadjuvant chemotherapy may alter these expression patterns in patients suffering with breast cancer. METHODS: We determined the protein expression levels of estrogen receptor (ER), progesterone receptor (PR), p53 and HER-2/neu in the preoperative core needle biopsies and the final surgical specimens from 15 patients who received neoadjuvant chemotherapy between January 2002 and June 2007. As a control group, we analyzed the samples from patients who did not receive neoadjuvant chemotherapy. RESULTS: The pathologic complete tumor response rate (pCR) of the neoadjuvant chemotherapy group was 6.7% (1/15). Of those patients who did not achieve a pCR (n=14), no significant differences in the biological prognostic markers expression were observed between the two groups. Alteration of the ER or PR status occurred in 42.8% (6/14) of the patients after neoadjuvant chemotherapy and in 14.3% (2/14) of the control patients, showing there was no significant difference between the two groups (P=0.210). The hormonal receptor status was changed in 3 cases (21.4%) after neoadjuvant chemotherapy. CONCLUSION: There were no significant differences for the changes in the expression of ER, PR, p53 and HER-2/neu from the preoperative core needle biopsy to the final surgical specimens between those patients who had received neoadjuvant chemotherapy and those patients who didn't. However, changes of the ER or PR status and the hormonal receptor status occurred in 42.8% and 21.4%, respectively, of the patients who underwent neoadjuvant chemotherapy. As these changes may impact treatment, we suggest that immunohistochemical assay is necessary before and after neoadjuvant chemotherapy in patients with breast cancer.
