Ganglion cysts in the lateral portal region of the knee after arthroscopy: report of two cases

A ganglion cyst (GC) is a mucinous or gelatinous-filled benign tumor overlying a joint or tendon sheath, which commonly arises in the dorsal and volar wrist side but may occur anywhere in the body. Although cystic lesions around the knee are common, the occurrence of GCs are rare. Ganglia may arise from intra or extra-articular, soft tissue, intraosseous, or periosteal location. Symptoms may vary according to the size and location. After the more frequent performance of magnetic resonance imaging for the assessment of a knee joint, the number of incidental, asymptomatic lesions have been increasingly diagnosed. The etiology of GC remains unclear; however, trauma and a flaw in the joint tissues may explain its appearance. The authors report two cases of women aged 47 years and 37 years who presented pain and swelling in their left knees following arthroscopic partial medial meniscectomy. The former was surgically treated and had a favorable outcome, while the latter had conservative treatment and a gloomy outcom

Contrast Sensitivity in Microtropic and Anisometropic Eyes of Successfully Treated Amblyopes

Objectives: To assess and compare contrast sensitivity function in the previously amblyopic and non-amblyopic "normal" eyes of patients with microtropia and anisometropia who achieved 20/20 visual acuity after occlusion therapy. Materials and Methods: Contrast sensitivity was tested monocularly on both eyes of 34 successfully treated microtropic and 15 anisometropic subjects (visual acuity 20/20 in both eyes). Contrast sensitivity function was evaluated by CSV-1000E and age-matched nomograms were used (spatial frequencies of 3, 6, 12, and 18 cycles per degree [cpd]) for comparison. Results: The mean age of subjects was 11.2 +/- 1.3 years in the microtropic group, 9.8 +/- 1.7 years in the anisometropic group (7-12 years); the mean follow-up time was 16.4 +/- 3.2 months (12 to 92) in the microtropic group and 27.7 +/- 1.8 months (12-84) in the anisometropic group. Statistical comparison of the microtropic amblyopic eyes versus non-microtropic eyes showed significant differences at spatial frequencies of 3, 12 and 18 cpd (3 cpd, t= 2.8, p= 0.007; 6 cpd, t= 1.1 p= 0.261; 12 cpd, t= 2.2, p= 0.033; 18 cpd, t= 2.2, p= 0.030). When anisometropic eyes were compared with non-anisometropic eyes, there was a significant difference only at 12 cpd (t= 2.1 p= 0.049). The comparison of non-amblyopic eyes versus age-matched nomograms revealed no differences at any of the spatial frequencies (p> 0.05 for all). Conclusion: Contrast sensitivity was decreased in patients with amblyopia, especially in the microtropic group. The assessment of contrast sensitivity function may serve as a new parameter for termination of occlusion therapy

QT Dispersion Increases with Aging

Background: Age‐related changes in cardiovascular system are well‐known. Arrhythmias in elderly patients constitute most of the urgencies, consultations, or hospitalizations. QT dispersion (QTd) is a simple noninvasive arrhythmogenic marker to demonstrate the electrical instability of the heart. The aim of this study was to investigate how QTd changes with increasing age by calculating the QTd in the elderly and younger subjects. Methods: One hundred and forty‐six consecutive subjects (62 males and 84 females; age range: 18–82 years) were enrolled in the study. Sixty‐seven of the subjects were 65 years and over (mean age, 70 ± 4), 79 were younger than 65 (mean age, 37 ± 11). A 12‐lead ECG was recorded. The longest and the shortest QT intervals were measured manually on these ECG recordings. QTd was calculated from the formula, QTd = QTmax − QTmin. Results: Demographic features were similar between the two groups. QTd of the elderly group was found to be significantly higher than the younger group (35.6 ± 15.6 in elderly, 24.2 ± 12.4 in younger group, P < 0.001). A positive relationship was found between QTd and age (r = 0.415, P < 0.001). QTd was greater in female than in male (31.9 ± 16.7 ms vs 26.0 ± 11.3 ms, respectively, P = 0.018). Conclusions: Our study shows that QTd increases with advancing age. We think that long‐term follow‐up of these patients would be useful to show if there is any relationship between the clinical outcomes and the increase in QTd

Atrial Myocardial Deformation Properties Are Temporarily Reduced After Cardioversion For Atrial Fibrillation And Correlate Well With Left Atrial Appendage Function

Aim This study was conducted to evaluate whether left atrial strain and strain rate correlate well with transesophageal parameters of stunning after atrial fibrillation. Methods and results Twenty-two consecutive patients with chronic atrial fibrillation >= 3 months and < 1 year were enrolled in the study. Transthoracic (TTE) and transesophageal (TEE) echocardiography with color Doppler myocardial imaging were performed before, 1 day after and 10 days after successful cardioversion. Left atrial transthoracic strain (S) and strain rate (SR) from lateral, inferior and anterior atrial walls, left atrial appendage tissue velocities, strain and strain rate values were measured with offline analysis. Left atrial appendage emptying (LAAEV) and filling (LAAFV) velocities were obtained from transesophageal echocardiography. Left atrial transthoracic, and left atrial appendage strain and strain rates were significantly lower following 1 day after cardioversion (TTE S/SR, 5.0 +/- 2.8%/2.3 +/- 1.0; TEE (septal) S/SR, 7.6 +/- 3.6%/1.6 +/- 0.7). There was a good correlation between these parameters and LAAEV (LA systolic strain and LAAEV, r = 0.73, P = 0.007). Left atrial and LAA strain and strain rate values improved over time, and correlated well with LAAEV, measured 10 days after cardioversion. Conclusions Transthoracic atrial and TEE LAA strain and strain rate, which are quantitative measures of atrial function, are reduced after cardioversion, and recover subsequently. The good correlation between LAA function and TTE strain and strain rate suggests that TTE atrial parameters may help determine duration of anticoagulation.WoSScopu
