RESUMO

Tracheobronchopathia osteoplastica (TO) is a rare benign disease in which the anterior inner wall of the tracheobronchus changes because of abnormal chondrogenesis or ossification, while the posterior wall of the trachea is spared. The etiology is not clearly understood, but may relate with chronic infection, inflammation, and trauma. In some case studies, it has also been reported to be accompanied by other chronic diseases such as atrophic rhinitis and amyloidosis. However, Coexistence of TO and tuberculosis has rarely been reported, and has never been reported in Korea. Here, we report a case of a 70-year-old male patient who complained of hemoptysis and whose case was diagnosed as TO and pulmonary tuberculosis through bronchoscopy with bronchial washing and biopsy.

RESUMO

Infliximab is a chimeric IgG1 monoclonal antibody to tumor necrosis factor (TNF)-alpha used in the treatment of steroid refractory or dependent Crohn's disease (CD). Patients with active CD are more likely to experience stillbirth, preterm labor, or small for gestational aged babies. The safety of administering infliximab in pregnant patients is not well documented. A 25-year-old woman, who was diagnosed with small bowel CD three years ago, was admitted to our hospital due to the aggravation of abdominal pain. She had been treated with mesalazine, azathioprine and intermittent steroid for three years. After admission, she did not respond to steroid therapy, we decided to try infliximab. After the administration of infliximab, epigastric pain was relived and Crohn's disease activity index score decreased significantly. However after the fourth infusion of infliximab, the patient became aware that she was ten gestational weeks old pregnancy state After then, infliximab was stopped and maintained by mesalazine. The patient gave birth to a healthy baby via normal vaginal delivery without the recurrence of CD. This case suggests that infliximab administration is safe during the early period of pregnancy. Thus, we report this case with a review of literature.

RESUMO

Multiple endocrine neoplasia type 1 (MEN1) syndrome includes varying combinations of endocrine and non-endocrine tumors. There are also a considerable number of atypical MEN1 syndrome. In this case, a 68-yr-old woman was referred to the Department of Endocrinology for hypercalcemia. Five years ago, she had diagnosed as primary hyperaldosteronism and now newly diagnosed as parathyroid hyperplasia with laboratory and pathologic findings. Hurthle-cell thyroid cancer was also resected during the parathyroid exploration and small meningioma was found on brain MRI. Her general condition has markedly improved and her adrenal mass and meningioma are being closely observed now. We could find the loss of heterozygosity of the MEN1 locus in parathyroid glands, suggesting a MEN1-related tumor, but not a germline mutation. Considering a variety of phenotypic expression and a limitation of current molecular analysis, periodic follow up will be needed in patients with a MEN1-like phenotype.

RESUMO

Diabetic nephropathy (DN) is a progressive kidney disease that is caused by injury to kidney glomeruli. Podocytes are glomerular epithelial cells and play critical roles in the glomerular filtration barrier. Recent studies have shown the importance of regulating the podocyte actin cytoskeleton in early DN. The phosphoinositide 3-kinase (PI3K) inhibitor, wortmannin, simultaneously regulates Rac1 and Cdc42, which destabilize the podocyte actin cytoskeleton during early DN. In this study, in order to evaluate the reno-protective effects of wortmannin in early DN by regulating Rac1 and Cdc42, streptozotocin (STZ)-induced proteinuric renal disease (SPRD) rats were treated with wortmannin. The albuminuria value of the SPRD group was 3.55 +/- 0.56 mg/day, whereas wortmannin group was 1.77 +/- 0.48 mg/day. Also, the albumin to creatinine ratio (ACR) value of the SPRD group was 53.08 +/- 10.82 mg/g, whereas wortmannin group was 20.27 +/- 6.41 mg/g. Changes in the expression level of nephrin, podocin and Rac1/Cdc42, which is related to actin cytoskeleton in podocytes, by wortmannin administration were confirmed by Western blotting. The expression levels of nephrin (79.66 +/- 0.02), podocin (87.81 +/- 0.03) and Rac1/Cdc42 (86.12 +/- 0.02) in the wortmannin group were higher than the expression levels of nephrin (55.32 +/- 0.03), podocin (53.40 +/- 0.06) and Rac1/Cdc42 (54.05 +/- 0.04) in the SPRD group. In addition, expression and localization of nephrin, podocin and desmin were confirmed by immunofluorescence. In summary, we found for the first time that wortmannin has a reno-protective effect on SPRD rats during the early DN. The beneficial effects of wortmannin in SPRD rats indicate that this compound could be used to delay the progression of the disease during the early DN stage.

RESUMO

Bilateral vocal cord paralysis may occur as a result of mechanical injury during neck surgery, nerve compression by endotracheal intubation or mass, trauma, and neuromuscular diseases. However, only a few cases of bilateral vocal cord paralysis have occurred following short-term endotracheal intubation. We report a case of bilateral vocal cord paralysis subsequent to extubation after endotracheal intubation and mechanical ventilation due to severe pneumonia for 2 days.

RESUMO

BACKGROUND: Left ventricular (LV) torsion plays an important role in both LV systolic and diastolic function. Notwithstanding the fact that speckle tracking imaging echocardiography (STI) is a validated method to measure LV torsion, few data regarding the clinical significance of LV torsional parameters using STI on exercise capacity during exercise echocardiography were reported. METHODS: Fifty four participants completed the supine bicycle cardiopulmonary exercise echocardiography under a symptom-limited protocol. LV torsion was defined as the net difference between LV peak apical rotation, and basal rotation divided by LV diastolic longitudinal length. LV basal, and apical short-axis rotations at each stage were analyzed by STI. RESULTS: LV torsion measurement was feasible in 43/54 (80%) at peak exercise. The LV torsions were increased during exercise, and even until the recovery. Peak twisting, and untwisting velocities were significantly increased during exercise, but were decreased at recovery. As expected, baseline torsion was positively correlated with LV ejection fraction and baseline apical peak untwisting velocity has correlation with E/E' (r=0.50, p<0.01 and r=0.30, p<0.05, respectively). Interestingly, apical peak twisting velocity at peak exercise was significantly correlated with maximal O2 consumption and VO2 interval change (r=0.50, p<0.01 and r=0.33, p<0.05, respectively). CONCLUSION: It was feasible to measure LV torsion by STI at every step during exercise echocardiography, although the feasibility was relatively low at peak exercise. LV torsional parameters during exercise showed significant relations with exercise capacity as well as LV systolic and diastolic functions.

RESUMO

A study of the volume and linear measurements of the breast to determine new nipple positions for 142 subjects was undertaken. Volume determination was done by using the Grossman-Roudner device. The size and shape of the female breast may differ significantly, and such size and linear measurements have to be measured accurately prior to breast aesthetic surgery. Statistical analysis of these results are closely related to physical constitution(height, weight, chest circumference). There have been increasing changes in linear measurement and decreasing changes in breast volume during the last 10 years, The results were as follows: 1) the mean distance from the midclavicular point to the nipple was 19.5cm, the distance from the sternal notch to the nipple was 19.4cm, the distance between nipples was 18.6cm, and the areolar diameter was 3.3cm, 2) the regression equation for the midclavicular point to the nipple was 7.236+ 0.00077x height(cm)+ 0.233 x weight(kg), for the sternal notch to the nipple was 8.845-0.0039 x height(cm)+ 0.214x weight(kg), for the distance between nipples was 11.192 - 0.0033xheight(cm)+ 0.151x weight(kg), and for the areolar diameter was 4.031+0.02xheight(cm)-0.048 x weight(kg),3) the mean value of breast volume of the left side was 209.6cc, and that of the right side was 211.8cc, 4) the regression equation for the mean breast volume was -137.673 + 6.668 x weight(kg), which was equal to -528.414 + 9.115x chest circumference under the axilla(cm) and -468.420 + 8.298 x chest circumference across the nipple (cm). In conclusion, these data could be useful for numerous aspects of breast surgery, including augmentation mammoplasty, mastopexy, reduction mammoplasty, and correction of asymmetrical breasts as the standard for Korean females, if we know the body constituents (weight, chest circumference) before surgery.

RESUMO

Many fungi including Penicillium, Aspergillus, Gliocladium, and Thermoascus produce an epipolythiodioxopiperazine class of fungal metabolite, gliotoxin, which contirbutes the pathogenesis of fungal infection as an immunomodulator and cytotoxic agent. This study is designed to define the mechanism by which gliotoxin exerts the cytotoxic effect of gliotoxin on human promyelocytic leukemic cells, HL-60. Gliotoxin induces the apoptosis of HL-60 cells which is characterized by the ladder pattern fragmentation of DNA. Gliotoxin induces the activation of DEVD-specific cysteine protease in a time- and dose-dependent rnanner. It also increases the phosphotransferase activities of c-Jun N-terminal kinase1 (JNK1) and p38 in gliotoxin-treated HL-60 cells. Furthermore, gliotoxin decreases the activation of transcriptional activator, actiating protein (AP-1) and NF-kB. These results suggest that gliotoxin induces the apoptotic death of HL-60 cells via activation of DEVD- specific caspase as well as mitogen activated protein kinases (MAP kinases) including JNK1 and p38, and inhibition of transcriptional activators, AP-1 and NF-kB.

RESUMO

BACKGROUND: In patients with Turner syndrome, it is known that the presence of Y-specific sequence is correlated with the risk of gonadoblastoma development. Y-specific sequence are frequently present in marker chromsome which can not be easily identified by cytogenetic method, because it is very small in size and unstable during mitosis. So, in this study, karyotype of 30 patients with Turner syndrome analyzed by cytogenetic method and the presence of Y-specific sequence was identified by polymerase chain reaction (PCR). METHODS: Cytogenetic analysis was performed by Phytohemaggulutinin (PHA)-stimulated lymphocyte culture and G-banding by Wright stain without trypsin treatment. Four Y-specific sequences were amplified by PCR using specific primer for Sex determination on Y (SRY), Ameglonin like gene (AMGL), Y1.1-1.2 repeat sequence (Y1.1-1.2) and B fragment of DYZ1 (DYZ1-B). DNAs for PCR analysis were extracted from peripheral blood lymphocytes of preserved cell pellets which were harvested for cytogenetic analysis. RESULTS: Cytogenetic analysis revealed various karyotypes in Turner syndrome such as 45,X, 46,X,i(X)(q10), 46,X,del(X) including four cases of 46,X,+mar and three cases of 46,X,+r. It is could not identify Y-chromosome in this 30 patients with Turner syndrome. By PCR, three patients (10%) with Turner syndrome had at least one Y-specific sequence; one case of 45,X karyotype was amplified in SRY; one case of 45,X[9]/46,X,i(X)(q10)[1]/46,XX[10] was amplified in AMGL, Y1.1-1.2; one case of 46,X,i(X)(q10) was amplified in SRY, AMGL and Y1.1-1.2. None of case was amplified in DYZ1-B. CONCLUSIONS: PCR for amplification of Y-specific sequence was thought to be useful in detection of Y-chromosome, which might be helpful in early diagnosis of gonadoblastoma in patients with Turner syndrome.

RESUMO

BACKGROUND: Platelets can be stored for 3days at 22degrees C in conventional plastic bags plasticizer with di-(2-ethylhexyl)phthalate(DEHP). However, with such a short interval for storage, platelets could not be made easily available for thrombocytopenic patients. In vitro platelet function during 5 days of storage at 22degrees C was studied in a new plastic bag (second generation bag) which contained as plasticizer a tri (2-ethylhexyl)trimellitate and developed in Korea (Boin Medica Co.). METHODS: In vitro function (mean platelet volume, platelet distribution width, pH, platelet aggregation, platelet morphology and swirling phenomenon) was evaluated in 20 units of platelet concentrate at day 0, 2, 5 while mixing in 60 rpm platelet rotator at 22degrees C. RESULTS: At day 5, platelet count, mean platelet volume, platelet distribution width, pH, platelet aggregation, platelet morphology and swirling phenomenon were well maintained. pO2, pCO2 and HCO3- were 65.6mmHg, 43.4mmHg and 12.3mmol/L at day 5, respectively. CONCLUSION: The data indicate that the use of the new platelet storage container will permit satisfactory storage for at least 5 days at 22degrees C.
