Hyperostosis frontalis interna (HFI) presents irregular thickening of the frontal bone. Even though HFI is frequently seen during routine radiological imaging, it usually remains unrecorded owing to a common belief that it just represents an incidental finding or anatomical variant. Recent studies implied that HFI may be clinically relevant. Etiology of HFI is still debated, while presumptions are mainly based on altered sex steroids impact on skull bone growth. Some authors implied that frontal bone might be particularly affected by this condition due to specificity of its underlying dura. In this paper we present a 27-years old female patient with a treatment resistant headache. Head CT showed massive, irregular bony mass, with lobulated contours arising from the right frontal bone, but did not cross the fronto-parietal suture, spearing the superior sagittal sinus and skull midline. After surgery, histopathological analysis of the frontal bone sample in our patient showed thickening pattern similar to those described in micro-CT studies of HFI. Furthermore, in an attempt to test speculation of the possible role of estrogen in pathogenesis of HFI, we investigated the expression of α-estrogen receptors on dura of the frontal region. These analyses confirmed nuclear expression of estrogen on frontal region dural tissue, supporting previous speculation of the development mechanisms of HFI and contributing to a better understanding of this common condition of the frontal bone. Additionally, the presence of HFI may result in severe symptomatology, which could be misinterpreted and related to other disorders if HFI is not radiologicaly recognized and reported.Three female skeletons, dated back to the beginning of the 15th century were recovered during an archaeological excavation in the Guinigi Chapel in Lucca (Italy). Archaeological and historical sources indicated that the remains might be those of Paolo Guinigi's wives. At the beginning of the 15th century Paolo Guinigi ruled Lucca for nearly 30 years (1400-1429), providing a long period of wealth and peace to the city. In those years of power Paolo Guinigi married four women from different countries. This study is aimed at identifying the three skeletons of Paolo's wives found in the Guinigi Chapel. The three skeletons were identified using a multidisciplinary approach, by integrating historical, archaeological, anthropological, and isotopic data. The anthropological studies evidenced the biological profile of two adult women and of one adolescent female, in agreement with the historical descriptions of three of the four wives of Paolo Guinigi. The isotopic analysis supported the identification of each individual.The aim of the present study was to verify the lateral angle method for sex estimation by using computed micro-tomography. Two measurements of the anterior lateral angle of the internal acoustic meatus were assessed. The performed analysis revealed that the mean angle at the level of transverse crest of the fundus of the internal acoustic meatus in adults is significantly greater in females (45.58° vs. 39.68°; p less then 0.05). A 45° sectioning point was applied, and sex allocation using this measurement was correct in 81.81% of adult samples. In turn, when utilizing the measurement at the level of modiolus of the cochlea, we did not obtain a satisfactory result in sex classification (59.09%). In subadults (male and female samples), the anterior lateral angles were undifferentiated. https://www.selleckchem.com/products/lji308.html Thus, the conducted micro-CT analysis shows that the anterior lateral angle measurement method can be used as a preliminary indication of sex in adult individuals.Purpose. The importance of early diagnosis, bone-healthy lifestyle and medication is required for remaining fracture free. Dual-energy X-ray absorptiometry and ultrasound densitometry are widely used to screen osteoporosis and other bone structural diseases. Bioelectrical impedance analysis (BIA) devices can also estimate bone mineral content (BMC), but it has not been recommended for diagnostic purposes. The aim was to analyse whether low levels of the body composition' components and low bone mineral content can predict bone structural risk. Methods. Healthy pre- (n 235, 18-45 years) and postmenopausal women (n 137, 46-78 years) were enrolled to the analysis. BMC (kg) was estimated by InBody 720 analyser. Bone structure was measured by ultrasound DTU-One osteometer. Broadband ultrasound attenuation (BUA, dB/MHz), which estimates structural characteristics of trabecular bone, was used to assess bone structure. Body mass components were estimated by Drinkwater-Ross method. Results. Age changes of BMC, absolute and relative bone mass, muscle mass and bone structural parameters were analysed in women. BMC (r = 0.43, p less then 0.01), absolute muscle mass (r = 0.41, p less then 0.01) and absolute bone mass (r = 0.37, p less then 0.01) were highly correlated (Pearson correlation) with BUA in premenopausal women. In postmenopausal women weaker relationship was identified between BUA and its hypothetical predictive factors. Conclusion. BMC and other studied body mass components alone do not provide enough information to identify osteoporosis, but can complete and widen the screening methods for bone structural diseases. Bone mineral density of healthy premenopausal women with low BMC, low bone mass and/or low muscle mass values should be measured regularly.The association patterns between fetal biometry at the first, second and third trimester and neonatal size were analyzed using a dataset of 3814 singleton term birth taking place at the Viennese Danube hospital in Austria between 2005 and 2013. In this electronic medical record-based study, fetal biometry was estimated by the results of three ultrasound examinations carried out at the 11th/12th, 20th/21th and 32nd/33rdweek of gestation. In detail, crown-rump length, biparietal diameter, fronto-occipital diameter, head circumference, abdominal transverse diameter, abdominal anterior-posterior diameter, abdominal circumference, and femur length were determined. Birth weight, birth length and head circumference were measured within one hour after birth. Fetal head size, abdominal dimensions and femur length intercorrelated positively from the second trimester onwards and correlated significantly positively with neonatal size (r = 0.04 to 0.46). Despite these allometric associations between fetal and newborn parameters, principal component analyses showed that parameters indicating body fat/weight, head or brain size and skeletal growth load on separate components.
