BACKGROUND: Although it is well known that bone mineral density (BMD) loss occurs after menopausal transition, there are only few previous studies that describe differences of BMD and biochemical bone markers in women of pre- and postmenopausal periods. The purpose of this study was to find factors that contribute to loss of BMD after menopause and to show changes of BMD and biochemical bone markers during pre- and postmenopausal periods by retrospective cohort study. METHODS: This retrospective cohort study was performed from Jan. 1995 to Jan. 2001 at a health promotion center. Twenty one healthy perimenopausal women were enrolled. BMD and biochemical bone markers were checked more than two times during the study period. Changes of BMD and biochemical bone markers between pre- and postmenopausal state were compared by paired t-test. Pearson correlation and multiple regression were performed to find the contributing factors to loss of BMD after menopause. RESULTS: Postmenopausal BMD (164.65 36.34 mg/cm3) was significantly decreased to 16.49 16.91 mg/cm3 (P<0.001) as compared with premenopausal BMD (181.14 40.81 mg/cm3). In biochemical bone markers only urine deoxypyridinoline had a significant difference (3.30 3.97 nMDP/mMcre, P<0.05) Only premenopausal BMD contributed to decreasing rate of BMD between the two states and the loss of BMD after menopause (P<0.05). CONCLUSION: In perimenopausal healthy women, postmenopausal BMD was significantly decreased as compared with premenopausal BMD. And only premenopausal BMD was shown to be a contributing factor to decreasing rate of BMD between the two states and the loss of BMD after menopause. It suggests that premenopausal BMD is important in predicting postmenopausal osteoporosis and efforts to prevent loss of BMD before menopause can prevent progress of postmenopausal osteoporosis.

BACKGROUND: Interleukin-17 (IL-17)-producing T helper (Th) 17 cells are considered as a new subset of cells critical to the development of rheumatoid arthritis (RA). We aimed to investigate the distribution of Th1 and Th17 cells and their association with disease activity, and determine the Th17-related cytokine levels in the peripheral blood of RA patients. METHODS: Peripheral blood mononuclear cells from 55 RA and 20 osteoarthritis (OA) patients were stimulated with mitogen, and the distributions of CD4+Interferon (INF)+IL-17- (Th1 cells) and CD4+INF-IL-17+ (Th17 cells) were examined by flow cytometry. Serum levels of IL-6, IL-17, IL-21, IL-23, and tumor necrosis factor (TNF)-alpha were measured by ELISA. Erythrocyte sedimentation rate (ESR) and C-reactive protein (CRP) were recorded. The 28-joint disease activity score (DAS28) was also assessed. RESULTS: The median percentage of Th17 cells was higher in RA patients than in OA patients (P=0.04), and in active than in inactive RA (P=0.03), whereas that of Th1 cells was similar in both groups. Similarly, the levels of IL-17, IL-21, and IL-23 were detected in a significantly higher proportion of RA patients than OA patients and the frequencies of detectable IL-6, IL-17, and IL-21 were higher in active RA than in inactive RA group. The percentage of Th17 cells positively correlated with the DAS28, ESR, and CRP levels. CONCLUSIONS: These observations suggest that Th17 cells and Th17-related cytokines play an important role in RA pathogenesis and that the level of Th17 cells in peripheral blood is associated with disease activity in RA.

Granulocytic sarcoma is a localized tumor composed of immature cells of the granulocytic series. Most granulocytic sarcomas occur in the course of acute leukemia and the blast crisis of chronic leukemia. Rarely, however, it may present before leukemia becomes clinically apparent. It may also occur in patients with myeloproliferative disorders. It has been reported that it occurs in 3% to 9% of patients with acute myelogenous leukemia (AML) and the incidence of granulocytic sarcoma is reported to be higher in patients with t (8;21). However, epidural granulocytic sarcoma associated with t (8;21) is very rare. In this report, we describe a patient with AML associated with t (8;21) in whom the cord compression occurred due to epidural granulocytic sarcoma. In addition, this case present infiltration of both pleura by blast cells. She was treated with local irradiation and chemotherapy successfully.

BACKGROUND AND OBJECTIVES: The prognostic impact of left axis deviation (LAD) on clinical outcomes in acute heart failure syndrome (AHFS) with left bundle branch block (LBBB) is unknown. The aim of this study was to determine the prognostic significance of axis deviation in acute heart failure patients with LBBB. METHODS: Between March 2011 and February 2014, 292 consecutive AHFS patients with LBBB were recruited from 10 tertiary university hospitals. They were divided into groups with no LAD (n=189) or with LAD (n=103) groups according to QRS axis < −30 degree. The primary outcome was all-cause mortality. RESULTS: The median follow-up duration was 24 months. On multivariate analysis, the rate of all-cause death did not significantly differ between the normal axis and LAD groups (39.7% vs. 46.6%, adjusted hazard ratio, 1.01; 95% confidence interval, 0.66, 1.53; p=0.97). However, on the multiple linear regression analysis to evaluate the predictors of the left ventricular ejection fraction (LVEF), presence of LAD significantly predicted a worse LVEF (adjusted beta, −3.25; 95% confidence interval, −5.82, −0.67; p=0.01). Right ventricle (RV) dilatation was defined as at least 2 of 3 electrocardiographic criteria (late R in lead aVR, low voltages in limb leads, and R/S ratio < 1 in lead V5) and was more frequent in the LAD group than in the normal axis group (p < 0.001). CONCLUSIONS: Among the AHFS with LBBB patients, LAD did not predict mortality, but it could be used as a significant predictor of worse LVEF and RV dilatation (Trial registry at KorAHF registry, ClinicalTrial.gov, NCT01389843).

BACKGROUND:
An implantable loop recorder (ILR) is an effective tool for diagnosing unexplained syncope (US). We examined the diagnostic utility of an ILR in detecting arrhythmic causes of US and determining which clinical factors are associated with pacemaker (PM) implantation.
METHODS:
This retrospective, multicenter, observational study was conducted from February 2006 to April 2018 at 11 hospitals in Korea. Eligible patients with recurrent US received an ILR to diagnose recurrent syncope and document arrhythmia.
RESULTS:
A total of 173 US patients (mean age, 67.6 ± 16.5 years; 107 men [61.8%]) who received an ILR after a negative conventional workup were enrolled. During a mean follow-up of 9.4 ± 11.1 months, 52 patients (30.1%) had recurrent syncope, and syncope-correlated arrhythmia was confirmed in 34 patients (19.7%). The ILR analysis showed sinus node dysfunction in 24 patients (70.6%), supraventricular tachyarrhythmia in 4 (11.8%), ventricular arrhythmia in 4 (11.8%), and sudden atrioventricular block in 2 (5.9%). Overall, ILR detected significant arrhythmia in 99 patients (57.2%) irrespective of syncope. Among patients with clinically relevant arrhythmia detected by ILR, PM implantation was performed in 60 (34.7%), an intra-cardiac defibrillator in 5 (2.9%), and catheter ablation in 4 (2.3%). In a Cox regression analysis, history of paroxysmal atrial fibrillation (PAF) (hazard ratio [HR], 2.34; 95% confidence interval [CI], 1.33–4.12; P < 0.01) and any bundle branch block (BBB) (HR, 2.52; 95% CI, 1.09–5.85; P = 0.03) were significantly associated with PM implantation.
CONCLUSION
ILR is useful for detecting syncope-correlated arrhythmia in patients with US. The risk of PM is high in US patients with a history of PAF and any BBB.
