<Emphasis Type="Italic">Demodex folliculorum</Emphasis> in patients with rheumatoid arthritis

The objective of this study was to investigate the incidence and density of Demodex folliculorum in the patients with rheumatoid arthritis (RA). Forty-one patients with RA and twenty-seven age and sex matched healthy controls were enrolled in this study. Disease Activity Score (DAS 28) was used for the assessment of disease activity. Out of 41 patients, 33 were females and 8 males. The mean disease duration was 10.9 ± 8.2 years. The mean DAS 28 was 3.8 ± 1.2. No statistically significant differences in the incidence and density of Demodex mites were found between patients with RA and controls. Although immunosuppression is thought to be a risk factor for the D. folliculorum infestation no such correlations could be found in the 41 immunosuppressed patients with RA, therefore, further studies with larger groups are needed.     

Chronic ovarian torsion after vaginal hysterectomy: a case with metastatic serous ovarian cancer

Ovarian torsion refers to partial or complete rotation of the ovary on its ligamentous support, often resulting in partial or complete obstruction of its blood supply. It is one of the most common gynecologic surgical emergencies and may affect females of all ages, but it is relatively rare in postmenopausal women. Chronic adnexal torsion with complete occlusion of the ovarian blood supply results in necrosis and loss of ovarian function. Clinical symptoms and signs are not specific and definitive diagnosis is often challenging. In this case report, we present a 65-year-old woman with chronic ovarian torsion that was detected 7 years after vaginal hysterectomy. Approximately 3% of postmenopausal cases with adnexal torsion are associated with malignancy. Ovarian torsion incidence is low in postmenopausal ovarian cancer due to the progression of accompanying inflammation, which causes immobility of the ovarian mass.     

The Impact of Mitral Stenosis on Left Atrial Function Assessed by Two‐Dimensional Speckle Tracking Echocardiography

Aims: The aim of this study is to investigate the effect of mitral stenosis (MS) on left atrial (LA) function using two‐dimensional speckle tracking echocardiography (2DSTE). Methods and Results: The study subjects consisted of 52 patients with asymptomatic MS and 52 control subjects. LA function was assessed using prototype speckle tracking software and manual tracking method. Maximal LA volume (LAVmax) and minimal LA volume (LAVmin) and LA volume before atrial contraction (LAVpre‐a) were measured. Using these volumes, LA reservoir, conduit and booster pump fuction parameters were calculated. Indexed LAVmax, LAVmin, and LAVpre‐a measurements via speckle tracking were highly correlated with manual tracing methods in both groups. Expansion index (67.8 ± 36.4 vs. 148.3 ± 44.2), diastolic emptying index (37.7 ± 12.9 vs. 58.0 ± 8.5), passive emptying (37.3 ± 14.1 vs. 70.4 ± 10.4) and passive emptying index (13.3 ± 6.3 vs. 41.3 ± 10.6) were decreased significantly in MS patients (P < 0.001). In contrast active emptying index (62.6 ± 4.1 vs. 29.5 ± 10.1) increased in MS group (P < 0.001) while active emptying (28.1 ± 13.0 vs. 28.3 ± 6.9) remained same among both groups. Conclusions: This is the first study relating LA volumes and function assessed by 2DSTE to MS. 2D speckle tracking analysis of LA volume is relatively easy and provides more detailed information regarding the changes in LA volumes during the cardiac cycle.
