BACKGROUND AND OBJECTIVE: The knowledge about the effects of the nebulized B2-agonist on serum potassium is limited. We aimed to assess the possible hypokalemia following nebulization of salbutamol. METHOD: Seven patients(mean age 60 +- 7.1years) with acute exacerbated asthma were treated with salbutamol nebulization(5mg nebulization at 1 hour interval, 3 times) without concomitant use of steroid or other bronchodilator such as theophylline. RESULTS: There was a significant increase in FEV1, from 46.41+-25.91% at baseline to 62.86+-22.38% at 3 hours after treatment. Serum potassium concentration was significantly decreased, from 3.93+-0.58mEq/L at baseline to 3.41+-0.62mEq/L and 3.46+-0.53mEq/L at 1 hour and 3 hours after third nebulization, repectively. There was a significant prolongation of the QTc interval in EKG from 454.36+-27.07msec at baseline to 479.41+-35.64msec and 505.09+-58. 69msec at 1 hour and 3 hours after third nebulization, respectively. Serum salbutamol concentration was 4.18+-3.39ng/ml at baseline, and increased to 7.69+-6.94ng/ml and 9.84+10.34ng/ ml at 1 hour and 3 hours after treatment, respectively. Magnitude of the hypokalemia and the degree of prolongation of the electrocardiographic QTc interval were significantly correlated with the level of serum salbutamol concenturation. CONCLUSION: The results suggest that cardiac complication could develop due to hypokalemia during repeated salbutamol nebulization. Caution should be done in monitoring of serum potassium concentration when using nebulized salbutamol repeatedly for the treatment of acute exacerbated bronchial asthma.

Thrombomodulin (TM) is thrombin receptor present on the luminal surface of endothelial cells. Because the thrombin-TM complex acts as an anticoagulant, the functional variants or deficiency of TM may lead to increment of thrombotic tendency. In this study, we screened the genetic variants of the TM gene in patients with myocardial infarction (MI) and analyzed the genotype to elucidate the effects of genetic variations of TM gene on the development of the MI. We screened a promoter region and coding sequence of the TM gene using single strand conformation polymorphism-heteroduplex analysis and identified three common genetic variants: those were TM G-33A, TM Ala455Val, and TM C1922T. The genotype frequencies were investigated in the patients with MI (n=234) and control subjects (n=291) by the method of allele-specific oligomer hybridization. The frequencies of mutant genotypes (TM -33A, TM 455Val, and TM 1922T) were higher in patient group compared to the control subjects in males while there were no significant differences in females. In the multiple logistic regression analysis, TM 455Val and TM 1922T alleles were independent risk factors for MI (OR[95% CI: 1.799[1.125-2.878] p=0.014 and 5.624[1.019-31.025], p=0.048, respectively) in males. However, the genetic variations were not independent risk factors for MI in females. There were significant linkage disequilibriums among three genetic variants. These linkage disequilibriums explain the similar effects of three genetic variants on the development of MI. To investigate the effect of the TM G-33A mutation on TM promoter activity, the two TM promoter constructs (pTM-355 and pTM-125, bearing TM -33G or TM -33A) containing of firefly luciferase gene were transfected into HepG2, BAE, and CHO cells. The promoter activities were higher in the promoter constructs with TM -33G compared to the constructs with TM -33A in pTM-355. These results suggest the possibility of the positive predisposing effect of TM -33A allele on MI in males. The functional study for TM Ala455Val and TM C1922T should be followed to elucidate the genotype effects of these mutations on the development of MI. In this study, we identified three genetic variants of TM gene and showed the significant associations between genetic variants and MI in males. These results proposed that TM gene is an attractive candidate for genetic risk factor for MI in Koreans.

In connective tissue diseases, autoantibodies cause pulmonary interstitial inflammation and fibrosis, and patients require treatment with an immunosuppressive agent such as a steroid. Dermatomyositis is an incurable, uncommon form of connective tissue disease that occasionally causes diffuse pulmonary inflammation leading to acute severe respiratory failure. In such cases, the prognosis is very poor despite treatment with high-dose steroid. In the present case, a 46-year-old man was admitted to our hospital with dyspnea. He was diagnosed with dermatomyositis combined with cryptogenic organizing pneumonia (COP) with respiratory failure and underwent treatment with steroid and an immunosuppressive agent, but the COP was not improved. However, the respiratory failure did improve after treatment with intravenous immunoglobulin, which therefore can be considered a treatment option in cases where steroids and immunosuppressive agents are ineffective.

PURPOSE: The results of all prostate biopsies may be positive and suggestive of adenocarcinoma in patients with prostate-specific antigen (PSA) values higher than 100 ng/ml. We considered that the prostate cancer in patients with high PSA might be advanced disease and therefore that the treatment strategy should not be changed according to pathological reports. Thus, we assessed the role of prostate biopsy when diagnosing prostate cancer in patients with extremely high PSA levels. MATERIALS AND METHODS: We reviewed the records of 1,150 cases undergoing prostate biopsies. Patients with urinary tract infection and acute urinary retention were excluded. According to the pre-biopsy PSA level, patients were divided into 6 groups (group A, 4 to 20 ng/ml; B, 20 to 40 ng/ml; C, 40 to 60 ng/ml; D, 60 to 80 ng/ml; E: 80 to 100 ng/ml; and F, above 100 ng/ml). RESULTS: The calculated positive predictive value (PPV) for prostate cancer was 22% in group A, 54% in group B, 73% in group C, 75% in group D, 89% in group E, and 100% in group F, respectively. Pathological diagnosis was adenocarcinoma in all patients in group F (n=56). Among them, 38 patients (67.9%) had lymph node metastasis or extra-prostatic disease or both and 43 patients (76.8%) had bony metastasis. In group F, all cases were advanced prostate cancer (stage III or IV). All of them received hormonal therapy following diagnosis. CONCLUSIONS: We suggest the possibility for biopsy-free diagnosis of prostate cancer in patients with extremely high levels of serum PSA and evidence of advanced disease in imaging studies, especially in older patients with comorbid medical problems.

Preoperative diagnosis of heterotopic pregnancy is difficult, especially when ectopic component is chronic and the precise effect of chronic tubal pregnancy on coexisting intra-uterine pregnancy or ongoing pregnancy rates is not known. We present the case of heterotopic pregnancy with a chronic tubal pregnancy incidentally diagnosed during term cesarean delivery in infertile woman conceived after ovulation induction using sequential clomiphene citrate and human menopausal gonadotropin, and timed coitus. Chronic tubal pregnancy might not affect the intrauterine gestation or the mother negatively in non-ruptured cases.

PURPOSE: To investigate the prevalence of amblyogenic risk factors in the primary family members (parents, siblings) of patients with exotropia. METHODS: The authors of the present study examined primary family members including parents and siblings of 58 exotropia patients in our clinic. Best corrected visual acuity, refractive error, and cover-uncover test were performed. A total of 49 normal children's family members (control group) were examined in a similar manner. The prevalence of significant ocular findings were determined and compared to the control group. RESULTS: In 58 eligible families (153 subjects except proband), 65.4% had significant ocular findings: In parents, anisometopia, astigmatism, hyperopia, and strabismus were found at a rate of 18.1%, 31.1%, 2.5%, and 11.2%, respectively. In siblings, anisometropia, astigmatism, hyperopia, and strabismus were found at a rate of 24.3%, 24.3%, 5.4%, and 18.9%, respectively. Compared to the control group, in parents of exotropia patients, anisometropia, astigmastim, and strabismus were observed at a higher rate. In siblings, anisometropia, and strabismus were observed at a higher rate. CONCLUSIONS: Primary family members of exotropia patients have a high prevalence of amblyogenic risk factors. The present study offers rationale for providing comprehensive eye exams for parents and children with a family history of exotropia.

A prospective study was initiated to compare maternal serum concentration of CA-125 during the first trimester of normal and abnormal pregnancies. Serum specimens were obtained from 87 women with a normal intrauterine pregnancy and 47 women with abnormal pregnancies which were ended in spontaneo abortion or pathologically confirmed to be missed abortion. In normal pregnancies, the mean serum CA-125 concentrations were increased significantly from amenorhea 6 weeks (139.838.7 IU/ml), and were higher statistically than the values tested in the same weeks of abnormal pregnancies. In abnormal pregnancies serum CA-125 concentations were relatively lower than those of normal pregnancies. But these differences were not statistically significant except the values tested in amenorhea 6weeks. So serum levels of CA-125 may not be proved useful in monitoring of early pregnancies outcome.
