This is called odontogenic maxillary sinusitis (OMS). Unilateral CMS is even believed to be induced by dental disease in approximately 75% of the cases. In bioarchaeology, odontogenic sinusitis has been somehow understudied, since very few archaeological studies on sinusitis have taken dental disease into consideration. Studying the impact of dental disease can give more contextualisation to previous studies on respiratory disease, including CMS. Both CMS and dental disease can be observable in archaeological context as various skeletal changes. This thesis research aims to test if the presence of CMS is related to the presence of dental disease within two post-medieval populations from Arnhem and Middenbeemster. The dental pathological conditions that are included here are periapical abscesses, periodontal disease, ante-mortem tooth loss and oroantral fistulae. First, the relation between CMS and dental disease has been investigated for the sample in its entirety, as well as on the intrasite level. After this, differences in the prevalence rates of OMS were investigated on the intersite level (i.e., between populations and between sex groups across populations). Chi squared tests and the Fisher’s Exact Test were used to test the hypotheses. The results show that there is no statistically significant correlation between the presence of chronic maxillary sinusitis and the presence of dental disease. Moreover, the differences in the prevalence rates of CMS did not hold any statistical significance either. It can be suggested that other factors, such as climate, smoking, or hazards as the result of urbanisation, have played a bigger role in the development of chronic maxillary sinusitis in the current sample. Although not significant, there was a stronger correlation between CMS and dental disease in the rural sample than in the urban sample. A stronger relationship was also observed in females than in males. Therefore, it might be suggested that dental disease played a more important role in the development of CMS among these subgroups. Furthermore, it is observed that OMS is slightly more prevalent in the urban population and has a slight female predominance.Show less

Prior to any comprehensive analysis, the reassociation of these remains is required. Over the past seven decades, numerous methodologies have emerged to address this challenge. However, each method exhibits limitations, prompting the necessity for the advancement of current techniques and the introduction of novel approaches. Among these evolving methods, the portable X-ray fluorescence technique stands out. Originally not designed for application on human remains, its appeal lies in its non-destructive nature and cost-effectiveness, drawing keen interest from osteoarchaeologists and forensic anthropologists. This study aims to evaluate the effectiveness of portable X-ray fluorescence in sorting commingled archaeological remains buried in the Netherlands. It involves the examination of 40 adults, 20 unearthed from Arnhem and 20 from Middenbeemster, dating back to the post-medieval period. The research initiates by investigating both intra-skeletal and inter-skeletal chemical variation, further exploring the potential factors contributing to these differences. Throughout the analysis, multiple sorting attempts are conducted to ensure a thorough exploration of the technique's capabilities. The results indicate statistically significant chemical variation within the same skeleton and among different individuals. In terms of intra-skeletal variation, from the 12 skeletal elements tested in each individual, only four pairs of bones (humerus–femur, rib–mandible, tibia–parietal, and tibia–rib) did not exhibit variation in the concentrations of chemical elements. With regard to inter-skeletal variation, 23 out of the 30 elements detected by the pXRF, and 14 out of the 15 ratios explored, demonstrated significant differences. Variation was also observed between males and females, as well as between sites. For the differences among the adult sub-groups that were noted, no generalizations can be made unless further research is conducted. Finally, the reassociation attempts reveal that the most successful sorting cases involved two individuals from different sites, utilizing principal components derived from ratios, while the tooth measurements were excluded. Key ratios influencing the sorting process included Mn/K, Mn/S, Mn/Fe, K/Fe, Sr/Ca, Ca/P, Pb/Ca, S/Sr, and Sr/Pb. While the method showed promise when a small number of individuals were involved, it lacked consistency. Therefore, it should be used in conjunction with other methods until further research is conducted.Show less

The vertebral pathological conditions that have been compared are vertebral osteoarthritis, osteophytes, intervertebral disc disease, Schmorl’s nodes and fusion. First, the prevalence of the vertebral pathological conditions have been compared between the Arnhem population and the three London populations. After that, the prevalence has been compared between the males and females within each population followed by a comparison of the prevalence across the age categories. The latter has been done for each population as well. Lastly, the male and female sample of the populations have been compared separately between the Arnhem population and the three London populations. To summarise, there does seem to be a relationship between vertebral pathology and social status in the Arnhem and London populations. Most vertebral pathological conditions are namely more prevalent in the low-status Arnhem population than in the higher status London populations. The prevalence of the vertebral pathological conditions in the lowstatus St. Arnhem population is similar to that of the low-status St. Bride’s Lower Churchyard population. Based on this, it can be inferred that the vertebral pathological conditions are more common in the lower status populations than in the higher status populations of this thesis. This could have been the result of the kind of labour these status groups were involved in. Furthermore, there does seem to be a difference in the prevalence of the vertebral pathological conditions between males and females; in three out of four populations (all except the St. Benet Sherehog population) males may have had harder working conditions than the females. When the prevalence in the male and female sample of the population were compared between Arnhem and the three London populations separately, a trend can be seen that may indicate that at least the males of the Arnhem population had harder working conditions than those in the other populations. The results have also shown that there are some biases. The first bias is that the statistically significant differences in the vertebral pathological conditions are more influenced by the male sample than by the female sample in all populations with Schmorl’s nodes likely being influenced by biological variation to some extent. Furthermore, the development of many of the vertebral pathological conditions are, at least to some extent, influenced by age in all populations.Show less

This condition is influenced by a combination of environmental and genetic factors, of which the most important for the context of this thesis are urbanization and air pollution, joined by overcrowding. Mastoiditis is closely associated with otitis media, as it often arises as a consequence of untreated otitis media. In the field of osteology, various diagnostic methods are used to identify otitis media, leading to a problem in comparison and verification of results obtained through different methods. So, what is the interrelationship of these methods? Do they produce similar results? The main aim of this thesis was to answer this question. To investigate the interrelationship of these diagnostic methods, a sample of 97 individuals from post-medieval Arnhem, the Netherlands, was analyzed. The methods selected for the analysis were chosen from diverse case-studies, with each method focusing on the analysis of a specific skeletal element. These elements included auditory ossicles, the temporal bone around the external auditory meatus, and the mastoid process. The method focusing on the mastoid process is utilized for diagnosing mastoiditis, rather than otitis media. In addition to the three primary methods, two other diagnostic approaches were included in the analysis. These methods involved the utilization of computed tomography (CT) scans to assess mastoid air cells pneumatization and endoscopic examination of the cochlear promontory. Dataset collected by Casna et al. (2023a) was used, as they were the ones utilizing these two methods. The findings of this study revealed relatively low concurrence rates among the three primary diagnostic methods, and even lower rates when all five methods were compared. The presence of such results called for an exploration of explanatory models that would aim to explain such low concurrence rates. Additionally, factors possibly influencing the results were also considered. This research underscores the need for developing a universal and standardized method for diagnosing otitis media. The lack of agreement among the diagnostic methods suggests not all of them are linked to the same underlying cause, therefore signifying the need for a better approach. While this research provided valuable insight into the interrelationship of some of the diagnostic methods, further research that would compare other methods that have not been compared here is necessary for better understanding of the complexity of situation surrounding otitis media diagnosis in osteoarchaeology.Show less

To be able to say something about care for these individuals I use historic literature, which functions as a historical framework, and I apply a bioarchaeological method known as the Index of Care, in which pathology found on skeletal remains form an important source of information. I will use pathology found on three skeletal individuals, from Arnhem, to say something about the living conditions of these people and what their quality of life might have looked like considering their disability. Based on the historic literature I provide the reader with an image of what care might have looked like for these individuals. And I research what this says about Arnhem’s population of the time and what their perspective was on their disabled and sick community. Arnhem would have different facilities in which people could be provided with care. Guesthouses played a major role in the caring for the city’s poor, sick and disabled community. In these guesthouses people could stay for a certain period of time up until a lifetime, depending on the guesthouses’ regulations. The church offered food, prayers and housing (also through guesthouses) to those in need as well. Additionally there were physicians and apothecaries that took care of the medical aspects of care for those who could afford it. However we must not forget that most of the disabled and sick individuals were most likely cared for by their relatives. The three individuals I analysed, must all have been cared for, for a longer period of time, most likely till their death. Based on these results and the historic framework, it is known that the lower class of Arnhem that was harshly disabled or sick would have been able to receive care if they needed to, and that this was provided by parties from different angles of society such as the church, the individual’s own social circle and the local guesthouses. This means that the early modern Arnhem cared for their disabled and sick population and that these people were seen as individuals that are entitled to housing, food a normal live and (medical)-care.Show less

It produced two datasets with matching criteria obtained from the skeletal assemblages of the heavily researched rural site of Middenbeemster and the relatively new urban site of Arnhem. Historical literature is combined with osteoarthritis prevalence give a more clear and detailed image of past activity patterns. This literature has provided this research with the knowledge that Middenbeemster was a dairy farming community, while Arnhem was a city with a focus on the beer brewing industry. Different markers on the bones associated with osteoarthritis resulted in differences in osteoarthritis prevalence. This differences were not only investigated within the environments but also between the environments. In the urban environment a sexual division of labour was seen, while in the rural environment men and women performed similar strenuous activities. Besides this, it is evident that industrial city life was more strenuous on the bodies of individuals than farming life was during the post-medieval period in the Netherlands.Show less

Furthermore, it is one of the diseases used in examining activity patterns within populations. This research makes use of two population samples, one with low-status individuals from Arnhem, buried in a cemetery outside the St. Eusebius’ Church, and one with high-status individuals from Zwolle, buried within the Broerenkerk. The aim of the research is to see if there are any remarkable differences between the prevalence of OA in the low-status population and the high-status population. To answer this question, 37 individuals from Arnhem and 55 individuals from Zwolle were analyzed. Males, females and indeterminate sexes were included in the sample as well as individuals from the early young adult age group to the old adult age group. 34 joints of all individuals (seventeen left and seventeen right) were scored plus the vertebral column and ribs. The scores were given on the basis of specific scoring systems for each joint and were put in a table ending up with a final score for all individuals. From these scores, it is evident that the females in Zwolle have a higher prevalence of OA than the females in Arnhem, the males of both samples are equally distributed. Considering the age groups, the two youngest age groups have a higher prevalence in the sample of Arnhem and the two oldest age groups have a higher prevalence in the sample of Zwolle. Status-difference might be the cause for these differences. However, the professions during the post-medieval period were similar in both cities. Regarding the most affected joints in both samples, the low-status population has the highest prevalence of OA in the arms, while the high-status population has the highest prevalence of OA in the legs. This difference could be explained by considering activity induced OA versus weight induced OA. Concluding from this study, there are some differences between the two samples regarding sexes and age groups. However, the total prevalence of OA in the Arnhem sample is slightly lower (5%) than the prevalence of OA in the Zwolle sample. Therefore, it seems unlikely that there is a difference between the prevalence of OA in low-status and high-status populations. This is confirmed by statistical analyses.Show less

In skeletal collections, these forms of status are studied using non-specific stress indicators. This research focusses on one nutritional status. Pelvic inlet morphology is repeatedly suggested to be a good proxy for nutritional status, but this never has been systematically analysed. This thesis examines pelvic inlet morphology together with other indicators, namely cribra orbitalia and maximum femoral length for two samples of different socio-economic status. This to verify the usefulness of the shape of the pelvic inlet as a nutritional status indicator. This research shows that the relationships between the different indicators are not significant, that they differ between subsamples and that they do not all follow the expected pattern. The correlations between pelvic morphology and cribra orbitalia, and between pelvic morphology and maximal femoral length, suggest that if pelvic morphology is influenced by periods of stress, it results of different causes of stress or different periods of stress than the other indicators, since most correlations are quite low and some of them contradict each other within subsamples. Furthermore, sex is found to influence individual measurements of the pelvis, but it has no real effect on the pelvic inlet index. Lastly, the individuals from Arnhem seem to have a slightly lower nutritional status than those from Zwolle, but differences are not pronounced. Even though the results are not significant and confounding factors are numerous, this is the first study that explores pelvic measurements in relation to nutrition for the Northern Europe and the first to provide pelvic data for Dutch samples.Show less

This will be done through the study of three Dutch towns ('s-Hertogenbosch, Arnhem and Deventer). The questions addressed in this study concern their characteristics (such as vaulting types, visible chronology and city specific types) and their functions (such as fire-safe spaces and general functions of medieval districts). The conclusions will highlight which characteristics are distinguishable. Primarily, that the 15th century is the appropriate era for cellars and that there is a large local variation with city-specific cellars, which is particularly the case in Deventer. An overview of the dimensions of all the investigated cellars is given. Cellars were not only used as storage, but also as a workshop or living space. They might also be related to city fires and the demand for fire-safe areas. Finally, cellars can only contribute to a limited extent to the identification of the functions of urban districts.Show less
