OBJECTIVES: This study was designed to assess the change of heart rate variability (HRV) at resting, upright, and psychological stress in anxiety disorder patients. METHODS: HRV was measured at resting, upright, and psychological stress states in 60 anxiety disorder patients. We used visual analogue scale (VAS) score to assess tension and stress severity. Beck depression inventory (BDI) and state trait anxiety inventories I and II (STAI-I and II) were used to assess depression and anxiety severity. Differences between HRV indices were evaluated using paired t-tests. Gender difference analysis was accomplished with ANCOVA. RESULTS: SDNN (Standard deviation of normal RR intervals) and low frequency/high frequency (LF/HF) were significantly increased, while NN50, pNN50, and normalized HF (nHF) were significantly decreased in the upright position compared to resting state (p < 0.01). SDNN, root mean square of the differences of successive normal to normal intervals, and LF/HF were significantly increased, while nHF was significantly decreased in the psychological stress state compared to resting state (p < 0.01). SDNN, NN50, pNN50 were significantly lower in upright position compared to psychological stress and nVLF, nLF, nHF, and LF/HF showed no significant differences between them. CONCLUSION: The LF/HF ratio was significantly increased after both physical and psychological stress in anxiety disorder, but did not show a significant difference between these two stresses. Significant differences of SDNN, NN50, and pNN50 without any differences of nVLF, nLF, nHF, and LF/HF between two stresses might suggest that frequency domain analysis is more specific than time domain analysis.

PURPOSE: The Bard Bladder Tumor Antigen(BTA) test is a latex agglutination assay that qualitatively detects the presence of basement membrane degradation complexes in the urine when the bladder tumor cells invade and destruct an extracellular matrix, called basement membrane. We evaluated the clinical significance of BTA test in the diagnosis and follow-up of patients with bladder cancer by comparing it with bladder washing cytology. MATERIALS AND METHODS: The Bard BTA test was compaired to bladder washing cytology in 26 patients with bladder cancer(group l), 18 undergoing surveillance cystoscopy for previous bladder cancer(group ll), and 10 suffering from other urologic diseases except bladder cancer(group lll). RESULTS: Of the group l patients, 84.6% were correctly diagnosed with the Bard BTA test compared to 69.2% with bladder washing cytology, which is statistically significant(p < 0.05). There was no difference in sensitivity according to tumor grade and stage. There was a high positive rate in group ll and lll patients probably due to the degeneration of basement membrane by other conditions such as intravesical BCG or mitomycin instillation, infection, or prostate cancer. CONCLUSIONS: The Bard BTA test is a non-invasive, simple, rapid, inexpensive adjunct to cystoscopy, and superior to bladder washing cytology in sensitivity, but many false positive results were observed. Further clinical evaluation is warranted to determine whether the false positive results are true or the result of inadequate number of patients studied.

BACKGROUND: In general, the outcomes of arthroscopic repair for superior labrum anterior to posterior lesions (SLAP) are favorable, however, persistent pain and limitation of motion are not rare complications. One of the possible cause is a “knot-ache”. This study evaluated the results of reoperation of symptomatic recurrent SLAP lesions and asked whether the knot is associated with postoperative complications. METHODS: Between 2005 and 2015, a total of 11 patients who had undergone arthroscopic SLAP repair were reoperated for recurrent symptomatic SLAP lesion. By retrospective chart review, operative findings, the visual analogue scale for pain (pVAS), the range of motion (ROM), and functional scores were analyzed. RESULTS: The mean age of the study participants was 38.3 years, and the mean follow-up period was 42.5 months. In the primary operation, there were nine cases of repairs with conventional knot-tying anchors and three cases with knotless anchors. Impingement of the knots during abduction and external rotation of the shoulder was observed in the all cases with knot-tying anchors. The mean pVAS, ROM, and functional scores significantly improved with reoperation. At the final follow-up, the mean satisfaction VAS was 8.3. CONCLUSIONS: The knots of suture anchor maybe a possible etiology of the pain, which we termed a “knot-ache”. Considering that reoperation is performed due to pain after primary repair, the use of knotless suture anchor may have benefits of eliminating one of possible cause, “knot-ache”. Therefore, authors suggest the use of knotless anchors during reoperation for recurrent or recalcitrant pain after primary SLAP repair.

Urinary hippuric acid was analyzed by gas chromatography/mass spectrometry method. A simple and economical derivatization procedure using excessive methanol in acidic condition was adopted to esterify hippuric acid. Quantitative analysis was performed with two internal standards, heptadecanoic acid and hydrocinnamic acid, to evaluate the derivatization procedure as an analytical method. Using the standard addition method, linear and reproducible calibration curves were obtained for both internal standards. Calibration experiment showed that good quantitative result could also be obtained with the calibration curve obtained without urine matrix. Recovery rates for the urine samples were in the range of 95.6~111.4%. Using hydrocinnamic acid as internal standard, analysis time could be reduced.

OBJECTIVE: 1) To compare prolactin responses to (and related clinical manifestations of) haloperidol, risperidone, and other atypical antipsychotics (clozapine, olanzapine, quetiapine, zotepine) with data from previous reports. 2) To investigate the association between changes in serum prolactin levels after the administration of antipsychotics and 44-bp insertion/deletion polymorphism in 5-HT transporter-linked polymorphic region (5-HTTLPR) in Korean schizophrenics. METHODS: The subjects were 136 patients diagnosed schizophrenic according to the DSM-IV criteria for schizophrenia who had taken antipsychotics for at least 3 months. The 136 patients consisted of the following 82 taking haloperidol (48 males and 34 females), 25 taking risperidone (14 males and 11 females), and 29 taking other atypical antipsychotics (18 males and 11 females). We measured serum prolactin concentrations by radioimmunoassay and investigated the clinical manifestations. We examined the genotype distribution and allele frequency of the 5-HTTLPR in all subjects by polymerase chain reaction of genomic DNA with primers flanking the promoter regions of the 5-HTT gene. Chi-square test, ANOVA and tukey test were used for statistical analysis with SAS 8.1 and p values of 0.05 or less were regarded as significant difference. RESULTS: Serum prolactin levels of patients taking haloperidol and risperidone were significantly higher than those taking other atypical antipsychotics (p<0.05). Females showed significantly higher prolactin levels than males (p<0.05). There was no significant difference in the genotype distribution and allele frequency of 5-HTTLPR among groups taking haloperidol, risperidone, and other atypicals. There was also no significant difference in genotype distribution and allele frequency of 5-HTTLPR between male and female schizophrenic patients. CONCLUSIONS: These results suggest that there was no association between serum prolactin levels after the administration of antipsychotics and 5-HTTLPR polymorphism in Korean schizophrenics.

Immunoglobulin G4-related disease (IgG4-RD) can involve any organ. The majority of reported cases involve IgG4-RD of the biliary tract or pancreas, while only two cases of pericarditis have been reported. A 58-year-old man visited the outpatient clinic of our institution with a seven-day history of progressive dyspnea. Based on his transthoracic echocardiogram and transesophageal echocardiogram, he was diagnosed with constrictive pericarditis. The histopathology of his pericardiectomy revealed the cause of constrictive pericarditis to be IgG4-RD. Prednisolone (40 mg) was initiated after the pericardiectomy. As the patient's symptoms resolved, he was discharged and followed-up on an outpatient basis. This is the first case report of constrictive pericarditis caused by IgG4-RD in Korea.

Purpose: Long-term culture- initiating cells(LTC-IC) are stem cells that have the capacities of long-term engraftment and helping to establish hematopoietic microenvironment. For evaluation of the LTC-IC, we measured the counts and function with multidimentional flowcytometry in long-term culture media. METHODS: Samples were obtained from umbilical cord blood, leukapheresis products and bone marrow(BM). LTC-IC were counted with flowcytometric analysis using anti- CD34, anti-CD38, and anti-HLA-DR antibodies at 0, 5, and 8 weeks. Cell adhesion molecule related with stem cell were evaluated with flowcytometric analysis also using anti-VCAM-1(CD106) and anti-VLA-4(CD49d) at 0 and 8 weeks. RESULTS: The proportion of CD34+/CD38- cell from fractionated mononuclear cells at 0 week were 0.46%, 0.044%, and 0.038% for BM, leukapheresis products, and umbilical cord blood respectively and then rapidly decreased at 5 weeks, but still persisted at 8 weeks in all three groups. The proportion of CD34+/HLA-DR- cells was the same tendency to CD34+/CD38-. VCAM+ expression rate from fractionated CD34+ cells at 0 and 8 weeks were 67.3% and 40.2% for BM and 64.1% 44.2% for umbilical cord blood but it was very low 31.2% and 5.1% for leukapheresis products. VLA-4+ expression rate for fractionated CD34+ cells at 0 and 8 weeks were similar tendency to VCAM+ cells. CONCLUSION: This study suggest that the count of LTC-IC decreased with time but still persisted until 8 weeks. Umbilical cord blood including BM help to establish the hematopoietic microenvironments.

The hospital standardized mortality ratio (HSMR) is a widely used generic measure for assessing quality of hospital care in many countries. However, the validity of HSMR as a quality indicator is still controversial. We critically reviewed characteristics of HSMR and suggested how to use HSMR as a quality indicator in the Korean setting. The association between HSMR and other quality measures of hospital care is inconclusive. In addition current HSMR model has shortcomings in risk adjustment because of the lack of clinical data, accuracy of disease coding, coding variation among hospitals, end-of-life care issues, and so on. Therefore, HSMR should be used as an indicator for improvement, not for judgement such as public reporting and pay-for-performance. More efforts will be needed to tackle practical and methodological weaknesses of HSMR in the Korean setting.
