OBJECTIVES: To reassess the long-term camouflage effects of resin infiltration (Icon, DMG, Hamburg, Germany) of white spot lesions (WSL) and sound adjacent enamel (SAE) achieved in a previous trial. The null hypothesis was tested that there were no significantly different CIE-L*a*b*-ΔE-values between WSL and SAE areas of assessment after at least 24 months (T24) compared to those at baseline (T0). MATERIALS AND METHODS: Of twenty subjects who received previous resin infiltration treatment of nteeth = 111 nonrestored, noncavitated postorthodontic WSL after multibracket treatment during a randomized controlled trial and were contacted 20 months after baseline, eight subjects (trial teeth nteeth = 40; m/f ratio 1/7; age range (mean; SD) 12-17 [15...

Gastric emptying rate in humans is subject to large individual variability, but previous research on the influence of genetics is scarce. Variation in the glucagon-like peptide-1 receptor (GLP1R) gene is a plausible candidate gene to partially explain the high variance. This study aimed to investigate the influence of genetic variation in the GLP1R gene on gastric emptying rate of a glucose solution in humans. Forty eight healthy Caucasian males took part in this investigation. Gastric emptying rate of a 6% glucose solution was assessed using the 13C breath test method and a venous blood sample was obtained from each participant...

Celiac trunk is the artery of foregut, arising from the abdominal aorta at the level of T12/L1 vertebral body. It extends approximately 1.5 to 2 cm horizontally forwards before dividing into three branches: left gastric, common hepatic, and splenic arteries. Out of the three ventral branches of abdominal aorta, celiac trunk is more prone to have variations. During routine dissection of abdomen for undergraduate students we found some rare variations in the branching pattern of the celiac trunk. Absence of celiac trunk with hepatomesenteric trunk, quadrifurcation with dorsal pancreatic artery arising from it, quadrifurcation with middle colic artery arising from it, left inferior phrenic artery arising from celiac trunk, highly tortuous splenic artery supplying distal 1/3rd of transverse colon and hepatosplenic trunk...

BACKGROUND: The optimal method for surgical treatment of early onset scoliosis is currently unknown. Although the aim of growth-friendly systems is to reduce the curve and maintain growth, there is no consensus on how to measure spinal growth during and after the treatment. Different measurements of different segments (T1-S1, T1-T12, instrumented length) are used for different time points to evaluate growth. The aim of this review is to assess what measurements are used and to compare the growth-friendly systems based on spinal growth during treatment...

BACKGROUND: Several preliminary analyses suggested an association between neprilysin levels and myocardial infarction. HYPOTHESIS: The objective was to assess whether Neprilysin (NEP) plasma levels following reperfusion might be a surrogate for infarct size (IS) or predict adverse outcomes in acute ST-segment elevation myocardial infarction (STEMI) patients. METHODS: We measured NEP levels in a prospective cohort of 203 patients with STEMI referred for primary percutaneous coronary intervention...

BACKGROUND: Knowledge of the ligamentum flavum anatomy is important for posterior spinal surgery. However, only a few studies have evaluated the relationship between the thoracic ligamentum flavum and its surrounding structures. This study aimed to clarify the anatomy of the thoracic ligamentum flavum. METHODS: The entire spines from 20 human embalmed cadavers were harvested in an en bloc fashion. All pedicles were vertically cut using a thread bone saw, and the ligamentum flavum from T1-T2 to T12-L1 was painted using a contrast agent containing an iron powder...

We aimed to examine whether ultrasound (US) is useful for evaluating spinal mobility and chest expansion in ankylosing spondylitis (AS) patients and determine a cutoff value to identify reduced sagittal lumbar mobility.Our cross-sectional study included 50 AS patients and 50 controls. Metric measurements and Bath AS indices were measured in AS patients. The distance between C6-C7, T11-T12, and L4-L5 vertebrae was measured, and the difference and percentage of difference between erect position and maximal cervical and lumbar flexion was calculated (T11-T12dif, T11-T12%, L4-L5dif, L4-L5%, T+L dif, T+L%)...

Introduction: Vertebroplasty (VP) is a well-known and effective therapeutic method for relieving the pain and improving the quality of life of patients with vertebral compression fractures. Major complications of VP are infrequent, occurring in no more than 1% of such procedures, whereas spinal subdural and epidural hematomas are extremely rare complications. Case Presentation: We present a unique case of a spinal subdural hematoma (sSDH) (from T4 to T12) occurring immediately after VP to treat a traumatic vertebral compression fracture, followed by a spinal epidural hematoma (SEH) (from T3 to T12) after the decompressive laminectomy, occurring in a 64-year-old patient...

Context: The location of the more superficial thoracic spinous processes is used to help osteopathic physicians locate the deeper and more difficult-to-palpate thoracic transverse processes. In 1979, Mitchell et al proposed the thoracic rule of threes to describe the relationship of the spinous processes to the transverse processes in the thoracic spine. This rule is currently taught at osteopathic medical schools. The rule of threes separates the thoracic vertebrae into 3 distinct groups, each with a different relationship between transverse processes and spinous processes...
