Metaproteomic analysis of King Ghezo tomb wall (Abomey, Benin) confirms 19th century voodoo sacrifices.

The palace of King Ghezo in Abomey, capital of the ancient kingdom of Dahomey (present-day Benin), houses two sacred huts which are specific funerary structures. It is claimed that the binder in their walls is made of human blood. In the study presented here, we conceived an original strategy to analyze the proteins present on minute amounts of the cladding sampled from the inner facade of the cenotaph wall and establish their origin. The extracted proteins were proteolyzed and the resulting peptides were characterized by high-resolution tandem mass spectrometry. Over 6397 distinct molecular entities were identified using cascading searches. Starting from without a priori searches of an extended generic database, the peptide repertoire was narrowed down to the most representative organisms-identified by means of taxon-specific peptides. A wide diversity of bacteria, fungi, plants, and animals were detected through the available protein material. This inventory was used to archaeologically reconstruct the voodoo rituals of consecration and maintenance of vitality. Several indicators attested to the presence of traces of human and poultry blood in the material taken. This study shows the essential advantages of paleoproteomics and metaproteomics for the study of ancient residues from archaeological excavations or historical monuments.

Is tetrodotoxin intoxication the cause of "zombi voice" in Haiti?

OBJECTIVE: Zombification, a magical and religious process in Haiti, has been scientifically studied and remains relevant. Originating from the convergence of African, Caribbean, and Christian rites, it involves a comatose trance, transforming individuals into living dead through Voodoo practices. Haitian zombies consistently exhibit a preserved expression marked by a nasal voice, a result of nasalization-using nasal cavities as resonators during phonation. The aim of this study was to ascertain the mechanisms through which zombification could impact the voices of the subjects. METHODS: A comprehensive investigation was conducted using both primary and secondary sources. Primary sources involved direct or reported testimonies of individuals undergoing zombification, with audio or video recordings available from the collections of the Laboratory of Anthropology, Archaeology, and Biology (UVSQ/Paris-Saclay University), as well as on the internet. Secondary sources encompassed the entirety of existing literature regarding zombification in Haiti on one hand, alterations in the voices of subjects when mentioned on the other hand, and toxicological hypotheses or evidence available on PubMed/Medline and Google Scholar. RESULTS: Few post-zombification observations exist, but 20th-century studies clarified the physio pathological process, confirming its reality. Wade Davis demonstrated in 1983 that zombification results from poisoning, with effects ranging from reversible to fatal, implicating substances like tetrodotoxin and datura. Nasalization can be natural or pathological, affecting various phonemes. No mutilating acts or surgery have been reported related to Haitian zombification. CONCLUSION: The pharmacological characteristics of tetrodotoxin, coupled with testimonials, present a medical hypothesis elucidating the biological mechanism underlying nasalization in this context. Given that tetrodotoxin induces flaccid paralysis as a neurotropic poison, its neurological impact could account for soft palate paralysis or spasms. Additionally, the severe hypotension induced by tetrodotoxin may elucidate oral and pharyngeal necrosis.

Pregnancy in Times of War: What Are the Fallouts? A Review.

BACKGROUND: The beginning of the conflict in Ukraine has reminded Europeans of the many and diverse consequences of armed conflicts. Indeed, the ever more sophisticated conflicts have led to the diffusion of numerous chemicals whose consequences spread even after the end of the war. We present through this paper a review of the consequences of pregnancies from the major conflicts that took place since the end of World War II. SUMMARY: MEDLINE, Web of Science, and Embase were screened for articles linking perinatal death (PD) or birth defects (BD) to wartime. A total of 50 papers treating 8 countries and 4 major and medically documented conflicts were included in the final analysis. An increase in BD and PD during and after the end of the conflicts was reported through all the conflicts analyzed. KEY MESSAGE: While more data are needed to conclude, maternal-fetal medicine specialists ought to be wary when dealing with exposed populations.

Three-dimensional reconstruction of King Henri IV's paranasal sinuses and mastoid cells.

PURPOSE: The preserved head of King Henri IV of France (life 1553-1610, reign 1589-1610) has survived to the present day thanks to high-quality embalming and favorable conservation conditions. The aim of this study was to examine Henry IV's upper resonant cavities and mastoids using an original and innovative forensic three-dimensional segmentation method. METHODS: The paranasal sinuses and mastoid cells of King Henri IV of France were studied by cross-referencing available biographical information with clinical and flexible endoscopic examination and computed tomography (CT-scan) imaging. The paranasal sinuses and mastoid cells were delineated and their volumes were assessed using ITK-SNAP 4.0 software (open-source). Graphical representations were created using Fusion 360® (Autodesk Inc., San Rafael, CA, USA) and MeshMixer® (Autodesk Inc., San Rafael, CA, USA). RESULTS: Paranasal sinus tomodensitometry revealed abnormalities in shape and number. Henri IV of France suffered from sinus aplasia. Neither the left sphenoid nor left frontal sinus contrasted sharply, and a remarkable pneumatization of the right clinoid processes extended throughout the height of the right pterygoid process. The total volumes of Henri IV's mastoid air-cells were estimated at 27 and 26 mL, respectively, for the right and left sides, exceeding the normal mean and the maximum of modern subjects by a wide margin. No sign of chronic ear or sinus condition was found. CONCLUSIONS: An innovative method has been developed in forensic medicine to establish hypotheses about the growth and respiratory conditions of the face.

Scurvy complicated with Capnocytophaga sputigena sepsis as a possible cause of death of king Saint-Louis of France (1270 AD).

The cause of death of Saint-Louis is not known, but recent findings indicated that he presented scurvy and inflammatory jaw disease, which has been associated with infection by oral commensals. Here, we have the exceptional opportunity to analyze the relics of the viscera of King Saint-Louis. A 4.3 g sample from the viscera relics of King Saint-Louis conserved in Versailles' cathedral was subjected to radiocarbon dating, electronic and optic microscopy, and elementary, palynological, molecular, proteomics and microbiological analyses including specific PCR and v3v4 16 S rRNA gene amplification prior to large-scale sequencing using an Illumina MiSeq instrument. The measured radiocarbon age was Cal 1290 CE-1400, which was compatible with that of the viscera of St Louis viscera, considering the addition of lime, incense and vegetables within the human organs. Elemental and palynological analyses confirmed a medieval embalming process. Proteomics analysis identified mainly human muscle and blood proteins. Specific PCR for plague, amoebiasis, shigellosis and typhoid fever was negative. C. sputigena was identified as the main pathogenic species representing 10.8 % of all microbial sequences. In contrast, C. sputigena was found in only 0.001 % of samples sequenced in our center, and the 23 positive human samples showed a dramatically lower abundance (0.02-2.6 %). In the literature, human infections with C. sputigena included odontitis, dental abscess, sinusitis, thoracic infections and bacteremia, particularly in immunocompromised patients with oral and dental diseases consistent with recent analysis of King Saint-Louis' jaw. C. sputigena, a commensal of the mouth that is potentially pathogenic and responsible for fatal bacteremia, may have been the cause of the king's death.

Henri IV of France's larynx 3D reconstitution.

OBJECTIVES: King Henri IV of France (reign from 1589 to 1610) was one of the most important kings of France. Embalmed and buried in Saint-Denis, his remains were beheaded in 1793. His head (including his larynx) survived in successive private collections until its definitive identification in 2010. The purpose of the study was to provide a morphologic study of the larynx with a 3D reconstitution. METHODS: A flexible endoscopy was performed via the mouth and via the trachea. Measures of the larynx (vocal folds lengths, thickness, width, larynx height) were collected from the CT-scan by a panel of experts blind each other. The segmentation of the laryngeal anatomical components (vocal folds, cartilages) was performed using 3DSlicer®. Mesh smoothing and 3D reconstitution were performed using Fusion 360®. Reconstitution was discussed between the experts. Decision was made by consensus after discussion. RESULTS: Cricoid, thyroid, arytenoid cartilages, vocal folds and hyoid bone were identified and a computed 3D reconstitution of the larynx was made. The laryngeal 3D model appeared morphologically similar to a living subject. Measures were similar but smaller than those of a modern subject. CONCLUSIONS: The 3D reconstitution of the larynx of Henri IV of France was conducted from the CT-scan of his mummified head. This work constitutes a first valuable morphologic analysis of a larynx from an embalmed individual. This anatomical work is the first step towards the reconstruction of the voice of this historical character, which we hope to concretize with computer modeling tools in a second step. LEVEL OF EVIDENCE: V based on experiential and non-research evidence.

Deep Paleoproteotyping and Microtomography Revealed No Heart Defect nor Traces of Embalming in the Cardiac Relics of Blessed Pauline Jaricot.

Scientific examination of the heart of Blessed Pauline Jaricot-a French missionary figure-was carried out in 2022. As tandem mass spectrometry proteotyping has proven to be valuable to obtain the broad taxonomic repertoire of a given sample without any a priori information, we aimed at exploring the conditions of preservation of the relics and possible conditions of death. Metaproteomics and high-resolution microtomography imaging approaches were combined. A dataset comprising 6731 high-resolution MS/MS spectra was acquired and 968 of these spectra could be assigned to specific peptidic biomolecules. Based on the taxonomical information encompassed by the identified peptide sequences, 5 phyla were identified amongst eukaryota (94% of the biomass): Ascomycota (55%), with the species Aspergillus versicolor, Trichophyton mentagrophytes and Aspergillus glaucus, corresponding to expected cadaverous fungal flora; Chordata (42%), represented by a unique species, Homo sapiens; Streptophyta (3%); and Arthropoda (traces). Bacteria (6% of the biomass) were poorly represented. No trace of embalming substance could be retrieved, nor any pathogens. Imaging evidenced no heart defect nor embalming traces. No evidence that was inconsistent with natural and spontaneous conservation could be retrieved. This study prefigures the power of modern molecular techniques such as paleoproteotyping coupled to microtomography to gain insight into historical relics.

The last jump: epidemiology of suicides at the Tour Eiffel (Paris) between 1950 and 1989.

The Eiffel Tower (Paris, France) has been attracting many candidates for suicide over the years. The aim of this study was to determine the patterns of people who committed suicide by jumping. Permission to access the unpublished records of the Paris Police Prefecture made it possible to compile press articles related to suicides from April 1950 to March 1989. 155 articles corresponding to 79 cases were kept for analysis. There were significantly more males (66%), as compared with an expected theoretical distribution of 1/2 for each sex (p = 0.002). Median age was 38.0 years old. Suicide peak was reached during the months of August and October (13% for each), while February was poor in suicides (3%). Tuesdays and Saturdays were the more impacted days. Hourly suicide rates were 8% (morning), 11% (noon), 7% (afternoon), and 5% (evening-night). Moon phases did not correlate with suicide occurrence. The main context described was that of a psychiatric pathology (49%). Death occurred in 92% of the reported cases. Sex ratio, ages, decrease during the cold season, no association with moon phases, and underlying psychiatric pathologies were consistent with trends for either all-cause suicides or suicide jumps from a platform. Conversely, unusual trough in suicides on Mondays and noon peak in suicide rate have been, respectively, attributed to small sample size and closure at night. As jumping corresponds to both ease and proximity, we believe the implementation of protective measures in the early 1960s succeeded in reducing the number of suicides overall.

Assessing signs of torture: A review of clinical forensic dermatology.

BACKGROUND: It is important for dermatologists and other physicians in refugee-receiving countries to acquire knowledge of forensic dermatology to identify lesions from torture. OBJECTIVE: Review forensic dermatology in cases of torture. RESULTS: In provision of medical assessment and care to refugees and migrants, chronic skin lesions will be the most readily identifiable signs of torture. Beatings are common, with blunt force trauma resulting in postinflammatory hyperpigmentation. Torture burns can be thermal, chemical, or electrothermal, causing distinct lesions determined by the method, duration, and intensity of exposure, and area of skin affected. Sharp instruments inflict a wide range of lesions arising from stabbing/perforation or cuts from knives. Wound healing without medical attention and in unsanitary conditions will affect the scarring process. Lesions from suspension and ligatures may occur alongside scars from other forms of torture. Differential diagnoses include self-inflicted wounds, ethnic scarification, and scars from traditional healing practices. CONCLUSION: Physicians who may encounter survivors of torture in community or specialist practice would benefit from basic training in forensic dermatology, whereas knowledge of common forms of torture and cultural practices in refugees' countries of origin is important when considering differential diagnoses of skin lesions.

Clinical agreement with self-report of physical violence and torture in women seeking asylum in France.

Women are a particularly vulnerable group among persons seeking asylum but are still required to provide clinical evidence of acts of violence inflicted against them. In this study the authors describe patient histories, dermatological lesions and other injuries arising from physical violence and torture in female asylum-seekers attending a specialist outpatient service in France. Twenty-seven women were assessed during 2016-2018. Clinical corroboration of lesions with patients' self-reports was affirmative in >90% (25/27) of cases. Health care services in recipient countries must be configured and resourced to support women seeking asylum, and health care professionals must be receptive and sensitive to women's self-reported histories.

Toxicological analysis of a "poison vial" found in the remains of an SS soldier (Maltot, Normandy, France).

In Maltot (Normandy, France), one grave containing the remains of a German soldier, who died in 1944, was excavated amongst other graves and isolated elements. A dozen whole vials were unearthed, resulting in questions about their content. Various screenings were carried out on the contents of one single vial: HPLC-DAD and HR-LC-MS screening after 1/10 dilution in mobile phase, GC-MS and HS-GC-MS after 1/10 dilution in methanol, multi-element research by HR-ICP-MS after total mineralization, and cyanide analysis. Analyzed vial contained approximately 300 µL of a colorless, water-immiscible liquid with a characteristic solvent odor. HPLC-DAD, GC-MS, HR-LC-MS/MS, ICP-MS, and cyanide screenings were negative excluding the presence of cyanide, arsenic, barbiturates, amphetamines, or narcotics. HS-GC-MS analysis highlighted the presence of ethanol, chloroform, and diethyl ether at significant concentrations. Chloroform and diethyl ether were anesthetic products mainly reserved for urgent situations. We hypothesized that the soldier may have been a combat medic working on battlefields. as he was wounded, another possibility could be that he may have used the vials to relieve his pain; however, the immediate severity of the wounds drove us to assess the second hypothesis of delayed death as being less plausible. The high number of vials containing ethanol, chloroform, and diethyl ether, and the massive blood loss leading to quick death led us to support the combat medic or paramedic hypothesis.

Why paleomedicine is useful for medical education.

What is the place of medico-historical cases in the professional practice of the disciplinary field of medicine and biology? How can these patients from the past be used for teaching and continuing medical education? How to justify their place in biomedical publications? In this article, we explain all the legitimacy of paleomedicine, and the need to intensify such research in the form of a well-individualised branch of paleopathology and the history of medicine.

Saint Roch and Social Distancing During Pandemics: Lessons to be Remembered.

Surprisingly, Catholic hagiography can teach us a lot about medicine. As an example, we present here the history of Saint Roch who is considered, along with Saint Sebastian, one of the two main Saints who act as protectors against plagues and have often been invoked by Catholic people during the recent COVID-19 pandemic. Whereas Saint Sebastian is associated with plagues only symbolically, Catholic tradition considers Saint Roch to have had real contact with the bubonic plague. Indeed, during his pilgrimage to Rome, Saint Roch helped people suffering from the plague and was, subsequently, himself infected. He was then forced to retire in solitary confinement to avoid the plague's spread and followed scrupulously the necessary restrictive measures. Saint Roch's story provides useful lessons about the importance of social responsibility by respecting the restrictive rules during difficult times such as the COVID-19 epidemic.

The first description of cholesteatoma by Hippocrate.

INTRODUCTION: Although otolaryngology became a subspecialty only since the middle of the nineteenth century, many diseases of ENT system, their clinical symptoms, universality and potential seriousness have been described since over 3000 years ago. Texts of the medical school of Cos and its founder Hippocrates (460-370 BC) collected in the Corpus Hippocraticum also contain multiple case reports and treatments for ear diseases. The aim of this study is to analyse an extract of one of Hippocrates' treatise, which apparently describes the first case of cholesteotoma. MATERIAL AND METHODS: We analysed a case from Epidemic by Hippocrates (VII, V, 1-9) from its English translation. RESULTS: Analysis of the description of symptoms allows us to diagnose a complicated cholesteatoma with facial palsy and neuro-meningitis manifestation. CONCLUSION: The meticulously detailed observations of the corpus give us a precious insight into the early perception of diseases and their evolution. The study of its history is of high interest to the fields of medicine, especially otorhinolaryngology. It also highlights the diseases and the suffering the diseases have inflicted on mankind since antiquity.

Leprosy in skulls from the Paris Catacombs.

Background: The Paris Catacombs contain the remains of approximately 6 million people dating back to the 15th century, when leprosy was endemic in France.Aims: The aim of this palaeopathological study was to identify the presence of leprosy in skulls from the Paris Catacombs.Subjects and methods: Macroscopic examination of skulls in situ for bone changes secondary to oronasal soft tissue infection by leprosy. Skulls were categorised as having "probable" signs of leprosy if they had an enlarged nasal (pyriform) aperture, resorption of the anterior nasal spine, and resorption of the alveolar processes of maxilla, and as having "possible" signs of leprosy if they met one of these three criteria.Results: Skulls from 123 sections within the Catacombs (approximately 1500 remains in total) were triaged, with 367 skulls identified as suitable for examination. Of these, 74 had central facial bone alterations/abnormalities and underwent detailed examination, yielding 0.5% (2/367) classified as having probable, and 5.7% (21/367) possible signs of leprosy.Conclusions: The proportion of skulls with probable signs of leprosy gives an approximate estimate (0.5%) for the prevalence of this disease in the population of Paris (or districts of Paris) during the 15-18th centuries.

French-style genetics v. 2.0: The "e-CohortE" project.

In the digital age, a genetics cohort has become much more than a simple means of determining the cause of a disease. Two-sided markets, of which 23andMe, Ancestry DNA and MyHeritage are the best known, have showed this perfectly over the last few years: a cohort has become a means of producing massive amounts of data for medical, scientific and commercial exploitation, and for genetic use in particular. French law does not currently allow these foreign private companies to develop on French national territory and also forbids the creation of similar entities in France. However, at least in theory, this same law does not preclude the creation of new types of cohorts in France inspired by the success of two-sided markets but retaining features specific to the French healthcare management system. We propose an optimal solution for France, for genomic studies associated with multi-subject questionnaires, still purely theoretical for the moment: the development, with no need for any change in the law, of France's own version of "Genetics v.2.0": "e-CohortE."

A Crouzon syndrome from the Classic period of Maya civilization?

This article describes a retrospective diagnosis through an artistic representation of a pre-Columbian Central America bowl figuring a child with clinical characteristics of Crouzon syndrome. The report also highlights the importance of icono-diagnosis for a better description of the existing diseases into ancient societies.

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"?

Did Frédéric Chopin Die From Heart Failure?

On October 17, 1849, Poland's greatest composer, Frédéric Chopin (1810-1849) died aged 39. His cause of death remains unknown. An investigation of the documental sources was performed to reconstruct the medical history of the artist. Since his earliest years, his life had been dominated by poor health. Recurrent episodes of cough, fever, headaches, lymphadenopathy- a series of symptoms that may be attributed to viral respiratory infections- manifested in his teens. Later in life, he had chest pain, hemoptysis, hematemesis, neuralgia, and arthralgia. Exhaustion and breathlessness characterized all his adult life. Coughing, choking, and edema of the legs and ankles manifested four months before his death. Several hypotheses ranging from cystic fibrosis to alpha-1 anti-trypsin deficiency and pulmonary tuberculosis have been proposed to explain Chopin's lifelong illness. We suggest that Chopin had dilated cardiomyopathy with consequent heart failure and cirrhosis that caused his death.
