Histological analysis and etiology of a pathological iguanodontian femur from England.

Derived ornithopods, such as hadrosaurids, show a high occurrence of fossilized lesions and diseases. However, paleopathologies in iguanodontians seem to be less common, considering the rich fossil record of these taxa in Europe, in particular in Belgium, Britain and Spain. Here, we describe an iguanodontian femur discovered in England that exhibits a large overgrowth of its lateral aspect, not previously recognized in any other similar remains. The specimen was scanned with micro-computed tomography (microCT) and later sectioned in three sites of the overgrowth for histological analysis. The femur belongs to an early adult Iguanodontia indet., based on the presence of a woven parallel fibered complex in the outer cortex and three to four lines of arrested growth. Internal analysis of the dome-like overgrowth suggests it can be diagnosed as a fracture callus. The injury might have negatively impacted upon the animal's locomotion as the trauma had occurred in the region above the knee, a crucial spot for hindlimb musculature. Finally, a cancellous medullary bone-like tissue was recognized in the medullary cavity next to the pathological overgrowth. An attempt was made to determine the precise nature of this tissue, as medullary bone is linked with the ovulation period in (avian) dinosaurs, whereas other types of endosteal, medullary bone-like tissue have previously been recognized in pathological bones.

A depiction of poliomyelitis in a 17th -century Piedmontese fresco?

INTRODUCTION: A potential representation of poliomyelitis is investigated in an Italian artwork. MATERIALS AND METHODS: A 17th century Piedmontese fresco is analyzed by combining historico-medical, palaeopathological and clinical approaches. Alternative diagnoses are considered. RESULTS, DISCUSSION AND CONCLUSIONS: The man appearing in the fresco holding a crutch is characterized by an atrophic left leg reminiscent of poliomyelitic atrophic. Other congenital anomalies or cerebrovascular causes appear less likely. A reflection on the difficulty of retrospectively diagnosis poliomyelitis is offered.

Unilateral Facial Asymmetry in a 40 BCE Roman Carved Head.

ABSTRACT: We describe the peculiar facial morphology of a carved head dating to the end of the Roman Republican period (40 BCE) which displays evident unilateral asymmetry. A comprehensive discussion of the different etiologies is provided and a contextualization of this condition in the broader frame of Roman artistic verism is offered. This case study contributes to the knowledge of disease presentation in the ancient world, with a special focus on the anatomy of soft tissue pathology.

The Greek hero Achilles and his mysterious death: transdisciplinary analysis of the gouty hypothesis.

Achilles is a character of Greek mythology whose deeds are mainly told in the Iliad by Homer. Achilles distinguishes himself on the battlefield of Troy with his dexterity and strength, appearing invincible, yet he dies wounded by an arrow in his heel. How could an arrow shot to the heel kill anybody, no matter whether vulnerable or invulnerable? Many researchers have tried to give a medical explanation to this mythological conundrum starting from a literary interpretation of the Homeric text: poisoning, infection, allergy, haemophilia or thyroid storm. In a way, the oldest medical interpretation was suggested by Lucian of Samosata (ca. 120 to after 180 AD). In his parodic tragedy "Gout", he claimed that the warrior actually died of gout. In this article we consider the gouty hypothesis and analyse the clinical aspects that support it.

Paleopathological study of a podal osteochondroma from the prehistoric Hypogeum of Calaforno (Sicily).

In this article, we report a case of isolated podal osteochondroma from the prehistoric Hypogeum of Calaforno (Giarratana, Ragusa, Sicily). Although the phalanx exhibiting the benign tumoral mass comes from a context featuring several commingled remains, the very good state of preservation of this bone allowed us to perform a comprehensive study of the neoplasm by applying a multidisciplinary approach encompassing archeology, morphology, stereomicroscopy, and radiology. The results from this very ancient specimen have been assessed in the light of the available paleopathological literature and clinical implications currently encountered in modern patients.

Wax hearts: seeking the antiquity of cardiac pathology.

Wax models of normal and diseased organs were formerly essential medical teaching tools. The ceroplastic heart models from two 19th century pathology museums at the Universities of Florence (n = 8) and Coimbra (n = 10) were analysed. The Florentine collection comprised congenital malformations as well as infectious and inflammatory disorders. The Coimbra waxworks included congenital defects, cardiac hypertrophy and dilation, valvular pathology and cardiac adiposity. This study focuses on heart diseases and teaching resources in European university hospitals during the 19th century. It also highlights the importance of wax models in medical education both then and today, in an era of informatics and digital photography.

First-time complete visualization of a preserved meningeal artery in the mummy of Nakht-ta-Netjeret (ca. 950 BC).

The preservation of the meningeal artery in ancient mummified bodies, particularly in anthropogenic Egyptian mummies, is a highly controversial topic in neuroscience and anthropological research. A recent (2015) debate between Wade and Isidro, based on the interpretation of the meningeal grooves and cast in a skull from the necropolis of Kom al-Ahmar Sharuna (Egypt), highlighted both the necessity of having clear radiological descriptions of this anatomical structure and of assessing large collections of mummified crania. Here, we present for the first time an instance of extremely well-preserved middle meningeal artery in the mummy of the ancient Egyptian dignitary Nakht-ta-Netjeret (ca. 950 BC), still inside the meninx, using paleo-radiological techniques. We finally link this find with experimental data from the neurological literature on the methodology of excerebration implemented by ancient Egyptian embalmers.

Correction to: Did Antonio Vallisneri (1661-1730) really describe frontal sinus osteoma? Unexpected insights for paleo-neuroparasitology.

The third sentence from the beginning in our article.

The antiquity of hydrocephalus: the first full palaeo-neuropathological description.

The Pathology Museum of the University of Florence houses a rich collection of anatomical specimens and over a hundred waxworks portraying pathological conditions occurring in the nineteenth century, when the museum was established. Clinical and autopsy findings of these cases can still be retrieved from the original museum catalogue, offering a rare opportunity for retrospective palaeo-pathological diagnostics. We present a historical case of severe hydrocephalus backed by modern-day anthropological, radiological and molecular analyses conducted on the skeleton of an 18-month-old male infant deceased in 1831. Luigi Calamai (1796-1851), a wax craftsman of La Specola workshop in Florence, was commissioned to create a life-sized wax model of the child's head, neck and upper thorax. This artwork allows us to appreciate the cranial and facial alterations determined by 30 lb of cerebrospinal fluid (CSF) accumulated within the cerebral ventricular system. Based on the autopsy report, gross malformations of the neural tube, tumours and haemorrhage could be excluded. A molecular approach proved helpful in confirming sex. We present this case as the so-far most compelling case of hydrocephalus in palaeo-pathological research.

The Gladiator's Tears: Epiphora From Ancient Rome.

This article examines the clinical presentation of epiphora in Ancient Rome through the historico-medical analysis of the literary evidence provided by the verses by the poet Juvenal in his Satire VI. A gladiator's ophthalmological problem is interpreted as epiphora caused by traumatic injuries to the craniofacial region, compatible with those described in the palaeopathological literature. This analysis also focuses on the history of epiphora in antiquity and its treatment.

The earliest known case of frontal sinus osteoma in man.

Frontal sinus osteoma is a relatively common finding in the modern clinical setting. Although, its paleopathological record is not in dispute, its presence in Ancient Egypt has never been clarified. The aim of this article is to contribute to the debate. An Egyptian mummy head from the Musée d'Éthnographie de Neuchâtel (Switzerland) was studied radiologically and the obtained evidence was contextualized in the wider frame of multidisciplinary paleopathology. A 128-slice CT scanner was used for further investigation; datasets were processed with OsiriX-64 bit (version 5.8.5), and multiplanar (MPR) and volumetric reconstructions were performed. A small hyperdense and well-defined structure, most likely an osteoma, was identified in the right frontal sinus. Frontal sinus osteoma definitely existed in Ancient Egypt. Finally, this represents the oldest case in anatomically modern humans so far reported. Clin. Anat.32:105-109, 2019. © 2018 Wiley Periodicals, Inc.

Poland syndrome before Alfred Poland: the oldest medical description (Paris, France, 1803).

Here, we present a description of Poland syndrome from the second session of the Anatomical Society (Paris, France) on 11 December 1803 of congenital mammary absence and muscular atrophy on the right side. This case report predates the first official description of the disease published by Alfred Poland in Guy's Hospital Reports (London, 1841). Consequently, perhaps would it be necessary to do justice to its French discoverer, and to name from now on this nosological entity the "syndrome of Marandel"?

A Case of Sudden Death in Decameron IV.6: Aortic Dissection or Atrial Myxoma?

Giovanni Boccaccio's Decameron contains a novella that details the sudden death of a young man called Gabriotto, including a portrayal of the discomfort that the protagonist experienced and a rudimentary autopsy performed by local physicians. The intriguing description of symptoms and pathologies has made it possible to read a 7-century-old case through the modern clinical lens. Thanks to the medical and philological analysis of the text-despite the vast difference between modern and medieval medicine-2 hypothetical diagnoses have emerged: either an aortic dissection or an atrial myxoma.

Untargeted metabolomics-like screening approach for chemical characterization and differentiation of canopic jar and mummy samples from Ancient Egypt using GC-high resolution MS.

In Ancient Egypt it was common practice to embalm corpses and specific internal organs to ensure eternal life. The exact nature of the employed embalming fluids, particularly for organ preservation within the canopic jars, is debated. Therefore, the aim of the current study, was to chemically characterize and differentiate canopic jars (n = 28) and mummies (n = 6) using gas chromatography - high resolution mass spectrometry (GC-HR MS) with a new untargeted metabolomics-like screening approach; as part of a larger minimal-invasive transdisciplinary study on Ancient Egyptian human tissues. Post-analytical data processing included deconvolution, screening against the NIST 14 spectral database as well as a high resolution metabolomics library, and positive peak evaluation. In the majority of samples the presence of a coniferous resin was indicated by the detection of longiborneol in combination with abietadiene acid derivatives and guajacol. Beeswax, proposedly used for symbolic reasons and/or as a binding agent, was detected in 10 samples. Previously not mentioned in the literature, but identified in the current sample set, were medical-related substances like aniseed constituents, salicylic acid, chamazulene and jacobine. By applying an untargeted metabolomics-like approach to archaeological samples for the first time, extensive statistical analysis was made possible (using both identified and non-identified features; adding up to 4381 features), which showed significant differences in the overall chemical composition of canopic jar and mummy samples using principle component analysis (PCA) and partial least square-discriminant analysis (PLS-DA). This emphasizes the necessity for more extensive canopic jar studies in the future in order to interpret findings correctly.

Gout in Duke Federico of Montefeltro (1422-1482): a new pearl of the Italian Renaissance.

The article examines the truthfulness of historical accounts claiming that Renaissance Duke Federico of Montefeltro (1422-1482) suffered from gout. By direct paleopathological assessment of the skeletal remains and by the philological investigation of historical and documental sources, primarily a 1461 handwritten letter by the Duke himself to his personal physician, a description of the symptoms and Renaissance therapy is offered and a final diagnosis of gout is formulated. The Duke's handwritten letter offers a rare testimony of ancient clinical self-diagnostics and Renaissance living-experience of gout. Moreover, the article also shows how an alliance between historical, documental and paleopathological methods can greatly increase the precision of retrospective diagnoses, thus helping to shed clearer light onto the antiquity and evolution of diseases.

Egyptian Canopic Jars at the Crossroad of Medicine and Archaeology: Overview of 100 Years of Research and Future Scientific Expectations.

Ancient Egyptian human remains have been of interest in the fields of both medical and Egyptological research for decades. However, canopic jar holders for internal organs (liver, lungs, stomach, intestines) of Egyptian mummies appear to be but a very occasional source of data for such investigations. The few medical approaches focusing on the content of these jars are summarized and listed according to pathogens and diseases to give a structured overview of this field of study. An extensive search of the literature has been conducted from different bibliographic databases with a total of n = 26 studies found. The majority of diseases found consisted of infectious diseases and internal medicine conditions such as schistosomiasis or emphysema. These are just 2 examples of many that, instead of primarily affecting bone, muscle or skin, specifically target internal organs. Hence, a better understanding of the evolution of diseases that still affect mankind could be gained. In conclusion, this reassessment shows that canopic jars represent a highly underestimated source for histological, radiological and ancient DNA examination of Ancient Egyptian remains and should, thus, be more and more brought back into the focus of retrospective medical research.

Did Antonio Vallisneri (1661-1730) really describe frontal sinus osteoma? Unexpected insights for paleo-neuroparasitology.

It has been believed for a long time that the Paduan scholar Antonio Vallisneri (1661-1730) described the second historical case of the frontal sinus osteoma in 1733. By historico-medically reexamining this case, we conclude that the brain concretions he described were not a case of frontal sinus osteoma, while they appear to have been pathological outcomes of neurocysticercosis, whose larval stages would only be described by Johann Goeze (1731-1793) later, in 1784. Thus, this case becomes relevant for the history of neuroparasitology.
