Effect of cold-pressed Nigella sativa seed meal on dough quality and nutritional value of bread.

This study investigated the application of black cumin meal (BCM) obtained from cold-pressing Nigella sativa seeds in bread baking. The effect of BCM on bread rheological traits and its nutritional value were investigated. Zeleny sedimentation, falling number, Farinograph, and Extensograph values in flour mixed with BCM (2.5%, 5%, 7.5%, and 10%) were evaluated. In addition, mineral content, protein, fat, thymoquinone, and crude cellulose contents in bread were investigated. Zeleny sedimentation and falling number values decreased with the increase in BCM in the flour samples. The water absorption, development time, stability, and softening degree values of the dough measured in the Farinograph device did not show a statistically significant difference in the flour with the BCM mixture compared to the control sample. The energy value and extensibility determined in the Extensograph device decreased with the increase in the amount of BCM in the flour. The amount of protein and crude fiber in bread increased with the increase in the amount of BCM. It was noted that there were significant increases in Fe, Ca, Mg, K, and Zn levels with the increase in BCM. Meanwhile, thymoquinone was not found in the bread samples containing BCM. The results revealed that the nutritional values of BCM-mixed bread are rich in protein, minerals, and cellulose.

Morphometric evaluation of cerebellar lobules in individuals with unilateral vertebral artery hypoplasia.

PURPOSE: Vertebral arteries (VAs) provide blood circulation to the posterior fossa in general and are the main blood supply of the posterior fossa structures of the brain. Our aim in this study is to analyze the segmental volumetric values of cerebellar structures with the voxel-based volumetric analysis system in individuals with unilateral vertebral artery hypoplasia. METHODS: In this retrospective study, segmental volumetric values/percentile ratios of cerebellar lobules were calculated using 3D fast spoiled gradient recall acquisition in steady-state (3D T1 FSPGR) MRI sequence images of the brain in individuals with unilateral vertebral artery hypoplasia (VAH) and in those without bilateral VAH and any symptoms of vertebrobasilar insufficiency as the control group was evaluated in volBrain ( http://volbrain.upv.es/ ). RESULTS: The VAH group consisted of 50 (19 males/31 females) and the control group had 50 (21 males/29 females) individuals. The cerebellar lobule III, IV, VIIIA and X total volumes and the cerebellar lobule I-II, III, IV, VIIIA and X gray matter volumes were lower in the hypoplastic side than the non-hypoplastic cases and also than the contralateral side of the hypoplastic cases in the VAH group. In addition, it was found that that lobules IV and V had lower cortical thickness and lobules I-II had a higher coverage rate in the intracranial cavity in the hypoplastic side than the non-hypoplastic cases and also than the contralateral side of the hypoplastic cases (p < 0.05). CONCLUSION: In this study, it was found that cerebellar lobule III, IV, VIIIA, X total volumes and cerebellar lobule I-II, III, IV, VIIIA, X gray matter volumes in addition to lobule IV, V cortical thicknesses were low in individuals with unilateral VAH. Being aware of these variations and taking them into account during future volumetric studies on the cerebellum are very important.

The relationship between the flexor and extensor muscle areas and the presence and degree of intervertebral disc degeneration in the cervical region.

BACKGROUND: This study aimed to investigate the relationship between the presence and degree of cervical intervertebral disc degeneration (IVDD) and the cervical region muscle areas. METHODS: The magnetic resonance imaging (MRI) examination of the patients who were sent to our clinic for investigation of neck pain between 2019 and 2020 years were evaluated retrospectively. 143 Turkish women patients between 30 and 40 ages were examined in the study. The presence and degree of IVDD was evaluated for each patient. The areas of the cervical flexor and extensor paravertebral muscles were measured. RESULTS: No cervical disc degeneration was present in 44 (30.76%) patients (grade 1). The cervical intervertebral disc degeneration was grade 2 in 28 (19.58%), grade-3 in 41 (28.67%), and grade 4 in 30 (20.97%) patients. In early stage degeneration (grade 2), an increase was observed in the area of all cervical paravertebral flexor and extensor muscles examined. As the degree of degeneration increased (grades 3 and 4), a decrease was observed in the areas of all muscles. Statistical significance was found for musculus (m) sternocleidomastoideus, m. levator scapulae, m. splenius capitis, m. semispinalis capitis, and m. multifidus muscles (P = .009, r = -0.261; P = .014, r = -0.248; P = .008, r = -0.267; P = .002, r = -0.307; P = .028, r = -0.222, respectively). CONCLUSIONS: IVDD is common in middle-aged females with neck pain. An increase in muscles areas is observed in the early stages of cervical disc degeneration but progressive decrease develops in all cervical paraspinal muscles areas as the degree of disc degeneration increases.

Relationship between cervical posterior subcutaneous fat tissue thickness and the presence and degree of cervical intervertebral disc degeneration.

OBJECTIVE: This study aimed to investigate the relationship between cervical region subcutaneous fat tissue thickness and the presence and level of cervical intervertebral disc degeneration (IVDD). METHODS: Magnetic resonance imaging examinations of patients referred to our clinic for the investigation of neck pain were evaluated retrospectively. A total of 300 women aged 30-40 years were included in the study. The presence and level of IVDD were evaluated for each patient. The cervical subcutaneous fat tissue thickness was also measured. RESULTS: IVDD was determined as Grade 1 for 88 patients (29.3%), Grade 2 for 56 patients (18.6%), Grade 3 for 82 patients (27.3%), Grade 4 for 60 patients (20%), and Grade 5 for 14 patients (4.6%). Subcutaneous fat tissue thickness was higher in patients with cervical disc degeneration (mean: 6.28 ± 0.19 mm) than in those without cervical disc degeneration (mean: 5.33 ± 0.18 mm) (P = .001). There was a positive correlation between the degree of cervical disc degeneration and subcutaneous fat tissue thickness ( = 0.001, r = 0.245). CONCLUSION: An increase in the cervical fat tissue thickness is a predisposing factor for the development of degeneration of the intervertebral disc. There is a close relationship between subcutaneous fat tissue thickness and the degree of degeneration.

Estimating the adequacy of the free quadriceps tendon autograft length using anthropometric measures in anterior cruciate ligament reconstruction.

OBJECTIVE: This prospective study aimed to predict the adequacy of free quadriceps tendon (QT) autograft length using simple anthropometric measures. MATERIALS AND METHODS: One hundred and eighty-four consecutive patients who underwent knee high-resolution MRI were enrolled in this study. The QT and native anterior cruciate ligament (ACL) length were measured using the oblique sagittal section. The adequate free QT length was calculated using the native ACL length and 30 mm for femoral and tibial tunnels in each patient. A QT shorter than the calculated length was considered inadequate. Age, sex, height, weight, body mass index, thigh circumference, and activity score were used to predict the adequacy of QT length with regression analysis. RESULTS: There were 92 men and 92 women with a mean age of 34.1 ± 8.0 years (range 18-45). The mean QT and ACL lengths were 69.0 ± 8.8 mm (range 48.1-90.3 mm) and 35.6 ± 2.5 mm (range 29.2-42.6 mm), respectively. The QT and the ACL lengths were longer in men (p < 0.001 for both). Twenty-three men and 39 women (total: 62, 33.7%) had inadequate QT length for a free QT autograft, and 6 patients (3 males, 3 females, 3.3%) had inadequate QT length with the bone block technique. There was a weak positive correlation between QT length and height (p < 0.001), weight (p < 0.001), and activity score (p = 0.007). Height was the only independent variable that predicted the QT length adequacy (r2 = 0.051, p = 0.009) but ROC analysis showed that height did not have an ability to detect a subject with an inadequate QT length (AUC: 0.384, 95% CI 0.300-0.468). CONCLUSIONS: Free QT autografts may be inadequate in one-third of the patients, while a QT autograft with a bone block is almost always sufficient. Inadequate free QT autograft is more common in women. Although QT length correlated with height, it cannot be used as an accurate diagnostic tool to identify patients with an inadequate QT autograft. Preoperative measurement of the ACL and QT lengths by MRI might be beneficial to decide whether QT is usable, especially when harvesting without a bone block. LEVEL OF EVIDENCE: Level II, diagnostic, prospective cohort study.

Comparison of the diagnostic efficacy and complications of transbronchial biopsy in elderly and young patients.

INTRODUCTION: Among bronchoscopic procedures, transbronchial biopsy (TBB) is considered a high-risk procedure. In this study, we aimed to investigate the indications, diagnostic efficacy and complications of TBB in the elderly, which is accepted as a sensitive group. MATERIALS AND METHODS: The study was designed as a multicenter retrospective observational study. Data of 4226 patients who underwent diagnostic bronchoscopy were scanned for this study. 791 patients who underwent transbronchial biopsy were included in this study. All patients were evaluated in terms of lung regions, diagnosis, and complications. RESULT: A total of 791 patients, 329 (41.6%) female patients, who underwent TBB were included in the study. Mean age of the patients was 54.54 ± 14.94 years. The most common indications were ILD (45.6%), malignancy (24.0%) and sarcoidosis (9.9%). Mean age of the elderly patients (n= 263) was 69.89 ± 4.83 years, and mean age of the young patients (n= 528) was 46.90 ± 11.28 years (p<0.001). In both age groups, the most common indication was ILD. Complications developed during and after the procedure in 51 of the young patients (9.7%) and in 21 of the elderly (8.0%) (p= 0.441). The most common complication was pneumothorax with 4.6% in the elderly, and pneumothorax with 5.9% in the young (p= 0.441). The most common diagnosis was malignancy (12.2%) in the elderly, as the most common diagnosis was malignancy (7.2%) in the young (p = 0.020). While anthracosis, ILD and organized pneumonia were the other common diagnoses in the elderly, sarcoidosis, anthracosis and organized pneumonia were the other common diagnoses in the young. The diagnosis of sarcoidosis was achieved more frequently in the young (6.6%) than in the elderly (0.8%) (p<0.001). CONCLUSIONS: Transbronchial biopsy can be performed safely in elderly patients, with similar diagnostic success and complication rates to younger patients.

The relationship between quadriceps fat pad syndrome and patellofemoral morphology: a case-control study.

BACKGROUND: The purpose of this prospective case-control study is to investigate the relationship between quadriceps fat pad syndrome (QFPS) and patellofemoral morphology. MATERIALS AND METHODS: Twenty-two patients with QFPS and 22 age- and gender-matched healthy volunteers were included. The diagnosis of QFPS was supported both clinically and radiologically. On magnetic resonance imaging (MRI), patellofemoral morphology was evaluated with 13 radiological measurements including trochlear sulcus angle, trochlear sulcus depth, trochlear facet asymmetry, trochlear condyle asymmetry, lateral trochlear inclination angle, patellar translation, tibial tubercle-trochlear groove (TT-TG) distance, Insall-Salvati ratio, patellotrochlear index, patellar tilt, the ratio between lateral and medial facet lengths, interfacet angle, and quadriceps tendon thickness. The mean of measurements was compared between groups using the Mann-Whitney U test. RESULTS: There were 22 patients (12 male, 10 female) with mean age of 30.81 ± 1.41 (range 19-38) years in group I and 22 patients (12 male, 10 female) with mean age of 31.13 ± 1.31 (range 19-39) years in group II. The mean age and the gender distribution were statistically similar between groups (p = 0.845, p = 1, respectively). All measured values except for patellar tilt (p = 0.038) and TT-TG distance (p = 0.004) were similar (p > 0.05 for the other variables). However, all of the measured variables were within the normal range. CONCLUSIONS: QFPS may not be associated with anatomical variations of the patellofemoral joint. Further studies are required to understand the etiology and risk factors. LEVEL OF EVIDENCE: Level III, prospective case-control study.

Recurrent stump appendicitis.

Acute appendicitis is one of the most common reasons for abdominal surgery. Stump appendicitis, one of the rare complications of appendicitis surgery, is an inflammation that develops in the remaining part of the appendix following surgery and occurs at a rate of 1/50.000 in cases with appendectomy. Although patients manifest the same findings as those with acute appendicitis on physical examination and laboratory tests, the history of previous appendectomy may cause delays in diagnosis.. Complications such as perforation and peritonitis can develop if an early diagnosis cannot be made. In this article, we present the first case of recurrent stump appendicitis reported in the literature as far as we are aware.

Retroperitoneal Teratoma with Secondary Infection.

Teratomas are germ cell tumors arising from the embryonic germ layers. Since they originate from the germ cells, they can be found in the gonadal, sacrococcygeal, mediastinal, intracranial, retroperitoneal, and cervical regions. In this case report, a 4-year boy, brought to the hospital due to abdominal pain and fever, was diagnosed as a large and infected peritoneal teratoma by contrast-enhanced abdominal computed tomography (CT) along with abdominal CT and operative findings.

Giant colonic lipoma causing intussusception: CT scan and clinical findings.

Colonic lipomas are uncommon and usually asymptomatic tumors. A 30-year-old woman with abdominal pain lasting 10 days was admitted to the surgical clinic. Her physical examination revealed sensitivity on the right upper quadrant and her bowel sounds were normal. A lesion and invagination findings in the colon were found in the ultrasound examination and CT was performed. CT scan revealed a lipoma and invagination in the colon and the patient has undergone surgery. Pathological diagnosis of the lesion was reported as submucosallipoma. In this case report, we present clinical and radiological findings of a submucosal colonic lipoma causing intussusception.

A promising tool for T-staging of lung cancer: Is convex probe endobronchial ultrasound superior to computed tomography in detecting invasion of mediastinal and hilar vessels?

BACKGROUND: In the present study, we aimed to compare performance of convex probe endobronchial ultrasound and computed tomography in detecting vascular invasion of mediastinal and hilar lesions. METHODS: Medical data of a total of 55 patients (47 males, 8 females; mean age 59.6±7.7 years; range, 29 to 76 years) who underwent convex probe endobronchial ultrasound for diagnosis and staging of lung cancer in a tertiary care hospital between May 2016 and December 2017 were retrospectively analyzed. The presence of vascular invasion was determined according to two main criteria: visualization of the tumor tissue within the vessel lumen and loss of vessel-tumor hyperechoic interface. All available contrast enhanced computed tomography images were retrospectively re-evaluated by a blinded radiologist. The intra-rater agreement between convex probe endobronchial ultrasound and computed tomography was analyzed. The sensitivity, specificity, positive and negative predictive values, and accuracy of both modalities were calculated. RESULTS: A total of 65 vessel-tumor interface areas of 55 patients were analyzed. Almost all mediastinal and hilar vascular structures including pulmonary arteries and veins, aorta, superior vena cava and its branches, and left atrium with pulmonary veno-atrial junctions could be easily assessed by convex probe endobronchial ultrasound. The intra-agreement of both modalities in detecting vascular invasion was k=0.268 (p=0.028). In nine patients with a surgical confirmation, the sensitivity, specificity, positive and negative predictive values, and accuracy values were 100%, 33.3%, 75.0%, 100%, and 77.7%, respectively for convex probe endobronchial ultrasound and 66.6%, 33.3%, 66.6%, 33.3%, and 55.5%, respectively for computed tomography. CONCLUSION: Convex probe endobronchial ultrasound can be used to detect vascular invasion alone or in conjunction with contrast-enhanced computed tomography. Hence, a T4 lesion would be better differentiated from T3 in clinical staging of lung cancer.

Can we use the contralateral glenoid cavity as a reference for the measurement of glenoid cavity bone loss in anterior shoulder instability?: a comparative analysis of 3D CT measurements in healthy subjects / ¿Podemos utilizar la cavidad glenoidea contralateral como referencia para la medición de la pérdida ósea de la cavidad glenoidea en la inestabilidad del hombro anterior?: un análisis comparativo de mediciones 3D TC en sujetos sanos

The purpose of this study was to compare the glenoid cavity measurements in healthy subjects. 100 adult subjects without shoulder pathology who had pulmonary computed tomography for any reason, were included in the study. Lung CT images were three-dimensionally rendered and glenoid cavity enface images were obtained. On these images, the glenoid cavity superior-inferior long axis and anterior-posterior equator, as well as the equatorial anterior and posterior radii, were measured. Dominant and nondominant glenoid cavity measurements were compared using the t-test in dependent groups. The long axis of the dominant glenoid cavity was 38.15 ± 3.5 mm, whereas it was 37.87 ± 3.3 mm on the non-dominant side (p = 0.068). The mean width of the glenoid cavity was 28.60 ± 3.3 mm in dominant glenoids cavities and 28.00 ± 2.9 mm in the non-dominant side (p = 0.0001). The equatorial anterior and posterior radii were significantly different between the two sides (p = 0.010, p = 0.001, respectively). The ratio of length to equator was different between the two sides (p = 0.012). The difference in equatorial lengths was 0.98 ± 0.8 mm (range, 0-4.2 mm). The mean difference between the long axis of the glenoid cavity was 1.2 ± 0.9 mm (range 0-4.6 mm). The equator on 69 individuals was larger on the dominant side. Glenoid cavity long axis was larger on the dominant side of 61 individuals. Glenoids cavities are not equal and not symmetrical to each other or influenced by hand dominancy. Measurements based on the assumption that both glenoids cavities are equal may be misleading.

El propósito de este estudio fue comparar las mediciones de las cavidades glenoideas en sujetos sanos. Se incluyeron en el estudio 100 sujetos adultos sin patología de hombro que tenían tomografía computarizada pulmonar. Las imágenes de CT de pulmón se representaron tridimensionalmente y se obtuvieron imágenes de la faceta de la cavidad glenoidea. En estas imágenes, se midieron el eje largo glenoideo superior e inferior y el ecuador anteroposterior, así como los radios ecuatoriales anterior y posterior. Las mediciones de las cavidades glenoideas dominantes y no dominantes se compararon usando la prueba t en grupos dependientes. El eje largo de la cavidad glenoidea dominante fue 38,15 ± 3,5 mm, mientras que fue 37,87 ± 3,3 mm en el lado no dominante (p = 0,068). El ancho medio de la cavidad glenoidea fue de 28,60 ± 3,3 mm en las glenoides dominantes y de 28,00 ± 2,9 mm en el lado no dominante (p=0,0001). Los radios ecuatoriales anterior y posterior fueron significativamente diferentes entre los dos lados (p=0,010; p=0,001, respectivamente). La relación de longitud al ecuador fue diferente entre los dos lados (p=0,012). La diferencia en las longitudes ecuatoriales fue de 0,98 ± 0,8 mm (rango, 0-4,2 mm). La diferencia media entre el eje largo de la cavidad glenoidea fue de 1,2 ± 0,9 mm (rango 0-4,6 mm). El ecuador en 69 individuos era más grande en el lado dominante. En 61 individuos el eje largo de cavidad glenoidea fue más grande en el lado dominante. Las cavidad glenoideas no son iguales ni simétricas entre sí ni están influenciadas por la dominancia de la mano. Las mediciones basadas en la suposición de que ambas cavidades glenoideas son iguales pueden ser engañosas.

Assessment of osteoporosis using the FRAX method and the importance of vitamin D levels in COPD patients.

BACKGROUND: The aim of this paper was to evaluate the availability of FRAX for assessing osteoporosis risk, and to demonstrate the importance of vitamin D levels in COPD patients. METHODS: Fourty-six males who fulfilled the COPD diagnostic criteria defined by GOLD were included. Age, race, BMI, physical activity frequency, smoking and dietary habits, age at COPD diagnosis, disease duration, fractures history, and medications use were determined. Levels of 25(OH)D were detected. BMD was measured by DXA at lumbar spine, femoral neck, and entire femur, and classified according to ISCD. FRAX score was calculated. Control group was composed of 40 non-smoker individuals without previous history of pulmonary diseases. RESULTS: 25(OH)D levels were significantly different between patients and controls. In the COPD group, a statistically significant difference in vitamin D levels was detected among the A, B, C, and D grades, while no such significant differences in FRAX scores were detected. 25(OH)D levels were significantly low in COPD patients with disease exacerbations and hospitalizations in the previous one year. No correlation was detected between vitamin D levels and the FRAX score. A positive correlation was observed between vitamin D levels and T-score. FRAX scores were higher and vitamin D levels were lower in osteoporotic COPD patients than in non-osteoporotic COPD patients. CONCLUSION: Using FRAX for assessing osteoporosis in COPD can reduce fracture risk and allow adequate treatment. Since vitamin D levels are related to exacerbations and hospitalizations, vitamin D supplementation may be needed in COPD patients, especially in those with high FRAX scores.

Bilateral Transverse (Bowdler) Fibular Spurs with Hypophosphatasia in an Adolescent Girl

Hypophosphatasia is a clinically heterogeneous inheritable disorder characterized by defective bone mineralization and the deficiency of serum and tissue liver/bone/kidney alkaline phosphatase activities. Due to the mineralization defect of the bones, various skeletal findings can be radiologically observed in hypophosphatasia. Bowing and Bowdler spurs of long bones are the characteristic findings. The Bowdler spurs reported on in the previous pertinent literature were observed in the perinatal aged patients and these lesions have rarely involved adolescents. We herein report on a 14-year-old girl with fibular Bowdler spurs.
