The aim of the study was to assess the incidence, localization, depth, length of myocardial bridging (MB) with left anterior descending (LAD), systolic compression ratio, atherosclerotic plaque localization and degree of stenosis by 256-slice multi-detector computed tomography (MDCT).Computed tomography (CT) scans from a total of 3947 patients who underwent MDCT were reviewed retrospectively for LAD MB. A diastolic and systolic dataset with the best image quality was selected. Myocardial bridge was defined as a coronary artery with an intra-myocardial course. Myocardial bridging was divided into "deep" or "superficial". The length and depth of the bridging segment were calculated. For each bridging segment, the presence of atherosclerosis was saved in a 2-cm-long segment proximal to the entry of the bridging segment. The degree of stenosis made by atherosclerotic plaques was determined.LAD myocardial bridging was detected in 410 (10.4%) patients. Among these, 97 (23.7%) patients had a deep and 313 (76.3%) patients had a superficial course. The mean LAD MB length was 20.28 ±9.63 mm and the depth was 1.72 ±1.11 mm. The systolic and diastolic mean diameter difference was 0.193 mm and the average compression ratio was 9.44%. Atherosclerotic plaques were found in 167 (40.7%) of 410 LAD MB. Atherosclerotic plaques were found in 50.5% of deep MB and 37.7% of superficial MB.256-slice MDCT coronary angiography has a high sensitivity to show myocardial bridging in LAD localization, to determine length, depth, compression ratio, atherosclerotic plaque localization and degree of stenosis.
Abstract Objective Vast majority of laboratory errors occurs in preanalytical phase and in vitro hemolysis is the most common among preanalytical errors. Automated serum index measurement is being used in routine biochemical analysis in Antalya Public Health Care Laboratory, since June 2014. Our aim in this study is to reveal the impact of serum index usage on rejected samples and rejected test rates due to hemolysis. Materials and methods Hemolysis, icterus and lipemia (HIL) spectral interference reagent and program have been used in our laboratory since June 2014. In the current study, the number of samples and tests that were rejected due to hemolysis in June–August 2014 were compared with those rejected in the same period of 2013. Results In 2014, the sample rejection rate was 2.53% and the rejected test rate was 0.48%. In 2013, the sample rejection rate was 0.56% and the rejected test rate was 0.55%. When compared two periods, statistically significant increase in rejected sample number due to hemolysis in 2014 is result of, visually undetectable hemolyzed samples previously can be identified by HIL method (p<0.05). Conclusion Usage of hemolysis index program in automated systems for detecting hemolysis was evaluated as a method which is standardized, semi-quantitative, with high reproducibility and allows test based rejection.
Introduction Osteochondral defects (OCDs) of the talus are treated initially by arthroscopic bone marrow stimulation. For both large and secondary defects, current alternative treatment methods have disadvantages such as donor site morbidity or two-stage surgery. Demineralized bone matrix (DBM) was published for the treatment of OCDs of rabbit knees. Autologous platelet-rich plasma (PRP) may improve the treatment effect of DBM. We previously developed a goat model to investigate new treatment methods for OCDs of the talus. The aim of the current study was to test whether DBM leads to more bone regeneration than control OCDs, and whether PRP improves the effectiveness of DBM. Methods A standardized 6-mm OCD was created in 32 ankles of 16 adult Dutch milk goats. According to a randomized schedule, 8 goats were treated with commercially available DBM (Bonus DBM, Biomet BV, Dordrecht, the Netherlands) hydrated with normal saline, and 8 were treated with the same DBM but hydrated with autologous PRP (DBM+PRP). The contralateral ankles (left or right) were left untreated and served as a control. The goats were sacrificed after 24 weeks and the tali were excised. The articular talar surfaces were assessed macroscopically using the international cartilage repair society (ICRS) cartilage repair assessment, with a maximum score of 12. Histologic analysis was performed using 5-μm sections, and histomorphometric parameters (bone% and osteoid%) were quantified on representative areas of the surface, center, and peripheral areas of the OCDs. Furthermore, μCT-scans of the excised tali were obtained, quantifying the bone volume fraction, trabecular number, trabecular thickness, and trabecular spacing in both the complete OCDs and the central 3-mm cylinders. Results All goats recovered well and were able to bear full weight within 24 hours after surgery. The mean ICRS-score of the ankles treated with DBM was 8.0 ± 1.0, compared to a score of 8.4 ± 1.5 in the contralateral ankle (NS); those treated with DBM+PRP scored 6.9 ± 2.4, compared to 7.4 ± 2.0 in the contralateral ankle (NS). Histologic analysis showed four different patterns of healing, distributed evenly over the treatment and control groups: type 1 (n = 4), almost completely healed; type 2 (n = 11), restoration of the subchondral bone with a cystic lesion underneath; type 3 (n = 14), superficial defect with regeneration from the margins and bottom; type 4 (n = 3), no healing tendency. Histomorphometry and μCT revealed no statistically significant difference between treatment (DBM or DBM+PRP) and contralateral control or between both treatment groups in any of the parameters investigated. Conclusion No treatment effect of DBM was found compared to control defects, and the addition of PRP was not beneficial.
Although there are a limited number of studies investigating the changes in olfactory bulb volume (OBV) and olfactory sulcus depth (OSD) values in the acute and subacute periods after COVID-19 infection, there are no studies conducted in the chronic period.The aim of this study is to reveal the changes in OBV and OSD after COVID-19 in the chronic period.A total of 83 people were included in our study, including 42 normal healthy individuals (control group) and 41 patients with COVID-19 infection (10-12 months after infection).The COVID-19 group included 41 patients with the mean age 40.27 ± 14.5 years and the control group included 42 individuals with the mean age 40.27 ± 14.4. The mean OBV was 67.97 ± 14.27 mm3 in the COVID-19 group and 94.21 ± 7.56 mm3 in the control group. The mean OSD was 7.98 ± 0.37 mm in the COVID-19 group and 8.82 ± 0.74 mm in the control group. Left, right, and mean OBVs and OSD were significantly lower in patients with COVID- 19 than the control individuals (all p < .05).Our findings show that COVID-19 infection causes a significant decrease in the OBV and OSD measurements in the chronic period.

Superior oftalmik ven trombozu (SOVT) nadir görülen bir patoloji olup etyolojisinde hiperkoagülasyon durumları, enfeksiyöz hastalıklar (enfeksiyöz sinüzit, orbital selülit), enflamatuar hastalıklar (sistemik lupus eritematozus, Behçet sendromu, sarkoidoz vb), neoplazmlar (lösemi, lenfoma, menenjiom), travma ve karotis-kavernöz fistül gibi durumlar rol oynar. Bilateral eş zamanlı gelişen SOVT ise çok nadir görülen ve erken tanı konulup tedavi edilmesi gereken bir durumdur. Tanı ve etyolojik nedenin belirlenmesinde manyetik rezonans görüntüleme (MRG) ve manyetik rezonans anjiyografi (MRA) önemli radyolojik modalitelerdir. Biz bu makalede remisyonda Non Hodgkin Lenfoma (NHL) olgusunda her iki orbitada eş zamanlı gelişmiş subakut evre SOVT' nin MRG bulgularını sunuyoruz.
Aim: The aim of our study is to evaluate the iliotibial band thickness (ITBT) and volume (ITBV) according to age and gender with 3 T MRI in a healthy Turkish population.
Material and Method: In the current study, 150 patients who had knee MRI were retrospectively evaluated. They were divided into the following groups to examine the effects of age: group 1: 18–30 years old; group 2: 31–40 years old; group 3: 41–50 years old; and group 4: 51–60 years old. ITBV measurements were performed on axial T2-weighted knee MR images.
Results: The mean age was 42.2±29.6 (range 18-60) years. The mean ITBT was 1.76±0.22 mm and the mean ITBV was 20,24±1,44 mm3 in all patients. There was statistically significant difference in mean iliotibial band thickness and volume between genders (p=0.001; p=0.001). There were no statistically significant differences in mean iliotibial band thickness and volume values between the groups in the one-way ANOVA test (p >0.05).
Conclusion: Radiological studies on iliotibial band thickness and band area in healthy individuals are new in the literature. This study is the first radiological study in which the volume of the iliotibial band was measured in healthy individuals and was performed on a 3 tesla MR device. Also, it is the first study that is used artificial intelligence for iliotibial band evaluation and the technic is effective and more rapid according to our experience. ITBV and ITBT are statistically significantly higher in males than females. Most thick ITB was detected between the ages of 31-40. The values of our study, especially ITBT, differ from previous studies and the values are altered in a wide range. Therefore, standardization in the calculation is necessary. This topic is open to future research.
