Abstract / Description
Osteoarthritis (OA) is one of the most common pathologies encountered in dry bone contexts. However, even with the wealth of publications on documenting the presence of OA from skeletons, these studies prove to be largely incomparable due to different scoring methodologies and procedures in calculating prevalence. The standardization of a new OA data collection procedure would mitigate variability in evaluating, scoring, and calculating the prevalence of OA, thus allowing accurate comparison...
Show moreOsteoarthritis (OA) is one of the most common pathologies encountered in dry bone contexts. However, even with the wealth of publications on documenting the presence of OA from skeletons, these studies prove to be largely incomparable due to different scoring methodologies and procedures in calculating prevalence. The standardization of a new OA data collection procedure would mitigate variability in evaluating, scoring, and calculating the prevalence of OA, thus allowing accurate comparison between studies. However, this level of data collection has often been described as unwieldy and lacking concordance. This research outlines a new methodology that utilizes Geographic Information Systems (GIS) to record OA characteristics, levels of expression, and spatial arrangement on the articular surfaces of the arm. The data was then processed using the analysis and visual rendering capabilities of GIS providing examples of OA patterning on the articular surface, within the joint, and within the individual. Using this method, large standardized OA datasets can be stored and the patterns within them modeled through the use of digitization, composite raster overlays, and modified binning techniques. The patterns recorded by this analysis can offer a more robust dataset on OA occurring within the arm that can provide the ability to explore OA progression and its relationship with biomechanical factors in larger datasets.

Abstract / Description
Osteoarthritis (OA) is a degenerative pathological condition of the appendicular joints which affects the cartilage and underlying bone. OA is relatively common in both the archaeological and clinical context, and a significant amount of research has been conducted on this osteological condition. The purpose of this thesis is to assess the incidence, demographic prevalence, and general severity of hip and knee OA in a Roman-Christian period (50 A.D (-) 450 A.D) population sample from the...
Show moreOsteoarthritis (OA) is a degenerative pathological condition of the appendicular joints which affects the cartilage and underlying bone. OA is relatively common in both the archaeological and clinical context, and a significant amount of research has been conducted on this osteological condition. The purpose of this thesis is to assess the incidence, demographic prevalence, and general severity of hip and knee OA in a Roman-Christian period (50 A.D (-) 450 A.D) population sample from the Dakhleh Oasis, Egypt. The bioarchaeological sample originates from the Kellis 2 cemetery which is associated with the ancient town of Kellis. The town of Kellis is believed to have been a prosperous economic hub in Egypt, located in the Western Sahara Desert approximately 250 kilometers west of the Nile. The skeletal samples (n=135, 83 females and 51 males) was visually assessed for the osteological characteristics of OA in the hips and the knees. Joint surfaces of the hip include the acetabulum and femoral head. Joint surfaces of the knee include lateral/medial tibio-femoral compartments and the patellofemoral compartment. The ages of the individuals assessed in this study range from 19-72 years, and have been divided into five age categories which were then cross-tabulated with sex and OA incidence in order to determine demographic prevalence of OA. Findings indicate that age is a significant etiological factor of OA prevalence for both males and females. Males are afflicted by the disease significantly more than females in the hips (F: [L] 3.6%, [R] 5.9% and M: [L] 13.7%,[R] 13.7%) and also slightly more affected in the knees(F: [L] 17.5%,[R] 18.3% and M: [L] 22.9%,[R]21.3%). The acetabulum tends to be more arthritic than the femoral head for both males and females. Femoral condyles tend to be more arthritic than tibial condyles for both males and females. The patello-femoral compartment tends to be the most arthritic part of the knee while the medial condyles of both tibiae exhibit virtually no OA (with the exception of one individual). The joint surface observed with the highest OA prevalence is the femoral surface of the patella (F: [L] 17.5%,[R] 15.9% and M: [L] 21.3%,[R] 21.3%). The highest prevalence of OA by joint complex is observed on the left knee in males (22.9%), and the lowest prevalence of OA is observed on the left hip of females (3.6%). Both hip and knee joints have higher prevalence of unilateral OA manifestation than bilateral. Isotopic and archaeological evidence indicates that the individuals at Kellis maintained an agricultural subsistence regime, and that the males within the population may have been highly mobile migrating to and from the Dakhleh Oasis. Subsistence agriculture has its necessary physical demands which may have been a contributory factor to OA rates. Males show higher OA rates than females throughout the joints of the legs. Sexual dimorphism of OA for the hips is suggestive of sexual divisions of labor. OA of the knees lacks sexual dimorphism therefore the knee joint complex of males and females were likely subjected to similar levels of mechanical loading. It can be concluded based on the OA data that males and females exhibit similar activity, or biomechanical stress levels in the knee joint complexes. Males exhibit significantly higher pathological manifestation of OA in the hip joint complexes, indicative of higher levels of mechanical loading in the hip joint complex which can theoretically be attributed to sexual divisions of labor or perhaps terrestrial mobility.

Abstract / Description
The present research seeks to assesses the presence and prevalence of two distinct dental pathologies: linear enamel hypoplasia and caries in an ancient Maya juvenile subsample from Altun Ha, Belize spanning the Preclassic (ca. 600 B.C.) through the Terminal Classic (ca. 900 A.D.) periods. Teeth offer a remarkable wealth of information about the human experience in the past.

Show moreThe present research seeks to assesses the presence and prevalence of two distinct dental pathologies: linear enamel hypoplasia and caries in an ancient Maya juvenile subsample from Altun Ha, Belize spanning the Preclassic (ca. 600 B.C.) through the Terminal Classic (ca. 900 A.D.) periods. Teeth offer a remarkable wealth of information about the human experience in the past. Developmental and post-eruption pathology can provide insight into cultural and evolutionary processes by illuminating social and biological factors such as diet, weaning, illness, and overall health that manifest in observable changes to the composition of teeth. In addition, growth and developmental stages of juveniles provide an ideal framework in which to qualify paleopathological research. From a biological standpoint, high ante-mortem resistance to physiological stress and post-mortem preservation make teeth ideal for analyses of pathology in archaeological contexts. For the analysis of the Altun Ha juvenile subsample, a cohort approach is used in the presentation and discussion of results. Discrete pathologies are analyzed based on age cohorts, individual, tooth type, tooth surface location, and archaeological time period. The results indicate an increase in prevalence of pathology concurrent with increasing dental age as well as a predisposition to pathology among specific tooth types and locations on the crown surface and within the dental arcade as well as temporal shifts in pathology prevalence. These analyses demonstrate the importance of assessing juveniles within the archaeological record with emphasis on the transitory developmental stages experienced by children.

Abstract / Description
The present study evaluates two fetal individuals (B532 and B625) from the Kellis 2 cemetery (Roman period circa A.D. 50 – A.D. 450), Dakhleh Oasis, Egypt, that display skeletal anomalies that may explain their death. Both individuals exhibit bowing of the long bones in addition to other skeletal deformities unique to each individual.

Show moreThe present study evaluates two fetal individuals (B532 and B625) from the Kellis 2 cemetery (Roman period circa A.D. 50 – A.D. 450), Dakhleh Oasis, Egypt, that display skeletal anomalies that may explain their death. Both individuals exhibit bowing of the long bones in addition to other skeletal deformities unique to each individual. To assess these pathologies a differential diagnosis based on the congenital occurrence of long bone bowing is developed. Long bone bowing is selected because it is the more prevalent abnormality in the paleopathological literature and the other abnormalities are not as easily identifiable in the literature. For the purposes of this study, the differential diagnosis is defined as a process of comparing the characteristics of known diseases with those shared by an archaeological specimen, in the anticipation of diagnosing the possible condition. It is expected that the differential diagnosis will assist in providing a thorough assessment of each skeleton and yield a possible diagnosis for the condition(s). Macroscopic and radiographic analyses are used to document and examine the bone abnormalities for each individual and compare the results with the developed differential diagnosis. Results suggest that the bent long bones of B532 were caused by osteogenesis imperfecta whereas the cause of the bent long bones of B625 is not clear. Further analyses of B625, including the pathologic abnormalities of its skull, suggest that the neural tube defect iniencephaly with associated encephalocele was the likely cause of the observed skeletal abnormalities. The abnormalities of the long bones complicate estimations of the age-at-death of these two individuals, thus the pars basilaris bone was used to assess age estimation. A population sample of 37 Kellis 2 fetal individuals allowed for the development of linear regression formulae of the pars basilaris measurements for long bone length estimates and a comparison of which would provide the most accurate age estimate. Finally, the diagnoses of the fetal specimens are considered in relation to the cultural aspects and disease pattern of the Kellis 2 cemetery

Abstract / Description
Vitamin C deficiency, or scurvy, is a disease that can occur in humans at any age and has been seen throughout time. Scurvy affects the production of connective tissues, including collagen, which leads to the many symptoms of the disease, including fatigue, anemia, bleeding gums and lost teeth, skeletal changes, and even death. The Kellis 2 cemetery in the Dakhleh Oasis, Egypt, in use from approximately AD 50-360, contains the remains of many juveniles who exhibit skeletal indicators of...

Scurvy affects the production of connective tissues, including collagen, which leads to the many symptoms of the disease, including fatigue, anemia, bleeding gums and lost teeth, skeletal changes, and even death. The Kellis 2 cemetery in the Dakhleh Oasis, Egypt, in use from approximately AD 50-360, contains the remains of many juveniles who exhibit skeletal indicators of scurvy. Tissue samples from juveniles who did (n=31) and did not (n=117) exhibit skeletal indicators of scurvy were analyzed isotopically, with the sample including stable carbon (?13C) and nitrogen (?15N) isotope values of bone collagen (scurvy =11, non-scurvy =13), hair (scurvy=21, non-scurvy=112), nail (scurvy =10, non-scurvy =44), and skin (scurvy =19, non-scurvy =59). Intra-tissue comparisons were conducted to determine whether this disease affects ?13C and ?15N values sufficiently to distinguish these two groups from one another isotopically. Inter-tissue comparisons between bone collagen and hair were also conducted, with emphasis placed on inter-tissue spacing results and outliers. Mean ?13C and ?15N values for each hair segment were compared to look for early isotopic signals of scurvy. No statistically significant differences were found between any intra-tissue scurvy and non-scurvy cohorts and no obvious indications of the onset of scurvy were seen in the hair segment analyses. The inter-tissue spacing results, however, highlighted some interesting patterns in the bone collagen-to-hair values, especially in regards to the identified outliers that are discussed in more detail. While this study did not detect any significant differences between scurvy and non-scurvy cohorts or early isotopic signals of the disease in hair segments, the inter-tissue spacing results do point to changes between the cohorts that may be attributable to the physiological stress of scurvy and therefore warrants further investigation.

Show moreFor centuries, people have been fascinated with how the ancient Egyptians lived, and particularly how they died. Although Egyptologists in the past had a greater interest in the treasures that accompanied the dead, there has now been a shift in focus on the actual ancient Egyptians themselves and their ways of life. Recognizing the health and disease status of ancient Egyptians has become particularly important. The aim of this research project is to document the paleopathology of the individuals from the sites of Dayr al-Barshā and Sheikh Said encompassing the Old Kingdom (2686 – 2160 BC), the First Intermediate Period (2160 – 2055 BC), and the Middle Kingdom (2055-1650 BC) periods. The site of Dayr al-Barshā was most importantly the necropolis, or burial site, used by the inhabitants of the ancient city of Hermopolis Magna, and it was also a very prominent quarry site. Today, Dayr al-Barshā is a large scale archaeological site that has been divided into eleven zones. The results of this research reveal a documented list of paleopathologies that include traumatic conditions, congenital anomalies, joint diseases, infectious diseases, hematological disorders, dental pathology, neoplastic conditions, and various other conditions that ailed the people in their daily lives. Fractures and dental diseases are the paleopathologies that occurred most frequently. These pathologies provide important knowledge about the living conditions and occupations during the span of the Old Kingdom through the Middle Kingdom.
