Ancient and modern pathologies and therapies: St. Gallicanus Hospital in Rome between the 18th and 20th centuries.

St. Gallicanus Hospital in Rome, Italy, created by the will of Pope Benedict XIII (1649-1730) in 1725, was the first dermatologic hospital in the world. The strong bond between science and faith, humanitarian spirit and scientific research, and the profoundness and legacy of its entire history have all contributed to its legacy. We have traced its development by examining archival documents to understand the life of the institute and the diseases that were diagnosed and treated from the 18th century to the first half of the 20th century. Some of the main diseases were leprosy, mange, scabies, ringworm, and syphilis, which were widespread in Rome during the 18th and 19th centuries and were creating a mortal threat for much of the population. St. Gallicanus Hospital was dedicated to the diagnosis, treatment, and prevention of these diseases where possible. Special attention has been directed to syphilis and the use of penicillin therapy after its introduction in 1943, especially for curbing the extensive problems created by prostitution.

Human major infections: Tuberculosis, treponematoses, leprosy-A paleopathological perspective of their evolution.

The key to evolution is reproduction. Pathogens can either kill the human host or can invade the host without causing death, thus ensuring their own survival, reproduction and spread. Tuberculosis, treponematoses and leprosy are widespread chronic infectious diseases whereby the host is not immediately killed. These diseases are examples of the co-evolution of host and pathogen. They can be well studied as the paleopathological record is extensive, spanning over 200 human generations. The paleopathology of each disease has been well documented in the form of published synthetic analyses recording each known case and case frequencies in the samples they were derived from. Here the data from these synthetic analyses were re-analysed to show changes in the prevalence of each disease over time. A total of 69,379 skeletons are included in this study. There was ultimately a decline in the prevalence of each disease over time, this decline was statistically significant (Chi-squared, p<0.001). A trend may start with the increase in the disease's prevalence before the prevalence declines, in tuberculosis the decline is monotonic. Increase in skeletal changes resulting from the respective diseases appears in the initial period of host-disease contact, followed by a decline resulting from co-adaptation that is mutually beneficial for the disease (spread and maintenance of pathogen) and host (less pathological reactions to the infection). Eventually either the host may become immune or tolerant, or the pathogen tends to be commensalic rather than parasitic.

The first probable evidence of leprosy in a male individual (17th-19th century AD) unearthed in Northern Portugal (Travanca, Santa Maria da Feira).

OBJECTIVE: This study describes the first evidence of a probable paleopathological case of leprosy from northern Portugal. MATERIALS: An adult male, skeleton 403, exhumed from the Christian cemetery associated with the church dedicated to Saint Mamede (Travanca, Santa Maria da Feira), dated from the 17th-19th century AD. METHODS: Standard bioarchaeological methods were used for sex and age-at-death determinations, and leprosy-related bone lesions were identified through macroscopic analysis guided by paleopathological diagnostic criteria. RESULTS: The macroscopic observation revealed probable leprosy-related skeletal lesions, namely tenuous rhinomaxillary changes, bilateral proliferative periosteal reactions on the tibiae and fibulae, as well as concentric atrophy, acro-osteolysis and ankyloses of foot bones. CONCLUSIONS: Skeleton 403 represents a probable case of leprosy according to the nature and distribution pattern of bony lesions observed. SIGNIFICANCE: This finding fills an important gap in the history of leprosy in Portugal. Although historical sources show that the majority of leprosaria were located in the northern part of the country, suggesting that leprosy was more prevalent in this area of Portugal in the past, no paleopathological evidence of this disease was reported for this region to date. Furthermore, the inhumation of a leprosy sufferer in a 17th-19th century AD Christian parish cemetery is deeply imbued with social meaning. SUGGESTION FOR FUTURE RESEARCH: The future detailed study of the remaining skeletons unearthed from the cemetery of the Church of São Mamede will hopefully reveal further osteological evidence of leprosy in addition to the application of ancient DNA analysis to confirm the presence of the pathogen of this disease. Also, further documentary research is needed in order to expand appreciation of the epidemiological and social impact of leprosy in the 17th-19th century AD Portugal.

Learning from the past in the COVID-19 era: rediscovery of quarantine, previous pandemics, origin of hospitals and national healthcare systems, and ethics in medicine.

After the dramatic coronavirus outbreak at the end of 2019 in Wuhan, Hubei province, China, on 11 March 2020, a pandemic was declared by the WHO. Most countries worldwide imposed a quarantine or lockdown to their citizens, in an attempt to prevent uncontrolled infection from spreading. Historically, quarantine is the 40-day period of forced isolation to prevent the spread of an infectious disease. In this educational paper, a historical overview from the sacred temples of ancient Greece-the cradle of medicine-to modern hospitals, along with the conceive of healthcare systems, is provided. A few foods for thought as to the conflict between ethics in medicine and shortage of personnel and financial resources in the coronavirus disease 2019 era are offered as well.

Genoa and leprosy: from the Middle Ages to the present.

During the Middle Ages, leprosy sufferers could not live in the city and were forced outside the walls. In the centuries, the Genoese area dedicated several hospitals to lepers, such as S. Lazzaro and Pammatone Hospital, a small leprosarium in the Tigullio area and San Martino Hospital from 1935. The first doctor who recognized to cure leprosy in Genoa was Goffredo, who later was also nominated rector of the community. In the early 1900's, Radaeli promoted the construction of a leprosarium behind the San Martino hospital. In 1936 Giuseppe Mariani was known for using the leprosarium to hide Italian Jews during deportation to the extermination camps. Later, Professor Aldo Baccaredda-Boy instituted the graduate school in "Leprosy and Tropical Dermatology", continued by professor Enrico Nunzi until 1990. The leprosarium was then transformed into the Department of Tropical Dermatology and finally into the Operative Unit of Social Dermatology, a national reference center.

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.

Mal de Meleda: A great imitator.

Mal de Meleda is an hereditary palmoplantar keratoderma named for the Mljet Island in Croatia. The lives of those affected by this disease represent a complex situation that encompasses members of a vulnerable group. They require enlightenment and should be approached with awareness, taking into account their overall psychophysical status and the environment of each patient. Those afflicted with Mal de Meleda not only have to deal with a difficult life due to their affliction, but they also must cope with the hardships of socialization while trying to realize a normal life within their island community. This is compounded by the frequent interviews and examinations of researchers interested in the various aspects of their illness. The subject of this contribution is not about the nature of this disease, rather about the traces it has left on the (sub)consciousness of the population. It is also concerned with exploring ways of how to access patients and understanding the depth of their vulnerability. We present some thoughts tied to the interpersonal experiences of researchers and patients afflicted with Mal de Meleda.

Tuberculosis and leprosy associated with historical human population movements in Europe and beyond - an overview based on mycobacterial ancient DNA.

Context: Tuberculosis and leprosy are readily recognised in human remains due to their typical palaeopathology. Both Mycobacterium tuberculosis (MTB) and Mycobacterium leprae (ML) are obligate pathogens and have been detected in ancient human populations. Objective: To demonstrate historical tuberculosis and leprosy cases in Europe and beyond using molecular methods, as human populations are associated with different mycobacterial genotypes. Methods: MTB and ML ancient DNA (aDNA) has been detected by DNA amplification using PCR, or by whole genome sequencing. Mycobacterial cell wall lipids also provide specific markers for identification. Results: In 18th century Hungary, the European indigenous MTB genotype 4 strains have been found. However, many individuals were co-infected with up to three MTB sub-genotypes. In 8th-14th century Europe significant differences in ML genotypes were found between northwest Europe compared with central, southern, or eastern Europe. In addition, several co-infections of MTB and ML were detected in historical samples. Conclusion: Both MTB and ML strain types differ between geographically separate populations. This is associated with ancient human migration after an evolutionary bottleneck and clonal expansion. The absence of indigenous leprosy in Europe today may be due to the greater mortality of tuberculosis in individuals who are co-infected with both organisms.

From isolation to prosperity: Rediscovering the Carville Leprosarium.

For centuries, patients afflicted with the peripheral nerve damaging disease, leprosy-sometimes referred to as Hansen's Disease-were excluded from society and harshly stigmatized. Such stigmatization often stemmed from the belief that the disease was a punishment by G-d for wrongdoing. Leprosy's origins remain rooted throughout various European countries; however, the disease established its presence in North America around the late 18th century. In particular, major port cities that experienced high volume trade, such as New Orleans, were most susceptible to infection. In response to the ensuing Louisiana leprosy endemic, various medical pioneers established the first hospital in America dedicated solely to the treatment of lepers, the Carville Leprosarium. The World Health Organization's treatment recommendation, multidrug therapy, is one of many lifesaving discoveries made at the facility located nearly 70 miles north of New Orleans. Since opening in 1894, the Carville Leprosarium has treated hundreds of Americans infected with Mycobacterium leprae, the disease-causing agent responsible for leprosy.

A synopsis of the history of Hansen's disease.

Leprosy is a contagious infectious disease caused by the bacillus Mycobacterium leprae. This microorganism was discovered by Dr. Gerhard Hansen, and the illness was then baptized as Hansen's disease. For a long time, Hansen's disease was thought to be hereditary-a curse or a punishment from God. The disease affects skin and nerves and can cause severe damage. Due to its destructive effects, leprosy has caused fear, segregation, and prejudice in all societies since Biblical times. Patients with Hansen's disease have not been treated humanely around the world throughout the ages. This article is a summary of curious and interesting facts about the history and cultural aspects of Hansen's disease, which has chastised humanity for centuries. These facts are about the discovery of the disease, its propagation, the evolution of treatments, and the prejudice of society towards patients.

The Medical Treatment of Vitiligo: An Historical Review.

Discolorations of the skin, such as vitiligo, were recognized thousands of years ago. White spots caused by vitiligo and other disorders have caused significant social opprobrium to those disfigured by these pigmentary disorders, throughout history and still in the present day. Treatments have been desperately sought with only partial success. Recent advances suggest that vitiligo and other pigmentary disorders might soon be curable.

Historical Overview of Leprosy Control in Cuba.

INTRODUCTION Leprosy, an infectious disease caused by Mycobacterium leprae, affects the nervous system, skin, internal organs, extremities and mucous membranes. Biological, social and environmental factors influence its occurrence and transmission. The first effective treatments appeared in 1930 with the development of dapsone, a sulfone. The main components of a control and elimination strategy are early case detection and timely administration of multidrug therapy. OBJECTIVES Review the history of leprosy control in Cuba, emphasizing particularly results of the National Leprosy Control Program, its modifications and influence on leprosy control. EVIDENCE ACQUISITION The historiological method was applied using document review, complemented by interviews with experts on leprosy and its control. Archived documents, medical records, disease prevalence censuses conducted since 1942, and incidence and prevalence statistics for 1960-2015 from the Ministry of Public Health's National Statistics Division were reviewed. Reports and scientific literature published on the Program and the history of leprosy in Cuba were also reviewed. DEVELOPMENT Leprosy has been documented in Cuba since 1613. In 1938, the Leprosy Foundation was created with ten dispensaries nationwide for diagnosis and treatment. The first National Leprosy Control Program was established in 1962, implemented in 1963 and revised five times. In 1972, leper colonies were closed and treatment became ambulatory. In 1977, rifampicin was introduced. In 1988, the Program instituted controlled, decentralized, community-based multidrug treatment and established the criteria for considering a patient cured. In 2003, it included actions aimed at early diagnosis and prophylactic treatment of contacts. Since 2008, it prioritizes actions directed toward the population at risk, maintaining five-year followup with dermatological and neurological examination. Primary health care carries out diagnostic and treatment activities. The lowest leprosy incidence of 1.6 per 100,000 population was achieved in 2006. Since 2002, prevalence has remained steady at 0.2 per 10,000 population. Leprosy ceased to be considered a public health problem in Cuba as of 1993. In 1990-2015, 1.6% of new leprosy patients were aged <15 years. At present, late diagnosis of cases exceeds 20%, which leads to a high percentage of grade 2 disability in such patients. Spontaneous physician visits by already symptomatic patients surpassed 70% of cases diagnosed in 2010-2015. CONCLUSIONS Actions undertaken after initial detection of leprosy in Cuba failed to control it. Effective control began in 1963, with the implementation of the National Leprosy Control Program, whose systematic actions have had an impact on trends in leprosy, reflected in WHO's 1993 declaration that leprosy was no longer a public health problem in Cuba.

Lepra: doença, isolamento e segregação no contexto colonial em Moçambique / Leprosy: disease, isolation, and segregation in colonial Mozambique

Resumo A partir de documentação produzida entre a primeira metade do século XIX e a primeira metade do século XX, prioritariamente relatórios médicos, o artigo aponta as concepções vigentes na comunidade médica colonial e entre as populações locais sobre a lepra, suas manifestações e seu enfrentamento. Enfoca as tensões quanto à prática de segregação dos leprosos e suas implicações sanitárias e sociais. Para compreender as raízes dos discursos e estratégias no meio médico português e colonial, recupera-se a trajetória das definições de isolamento, segregação, lepra e suas aplicações, ou ausência de referência, na literatura de missionários, cronistas e médicos em Angola e Moçambique a partir da segunda metade do século XVII.

Abstract Drawing on documents produced between the early nineteenth and mid-twentieth centuries, mainly medical reports, this paper indicates the prevailing conceptions in the colonial medical community and local populations about leprosy, its manifestations, and how to deal with it. It focuses on the tensions concerning the practice of segregating lepers and its social and sanitation implications. To comprehend the roots of the discourses and strategies in the Portuguese and colonial medical environment, the trajectory of the definitions of isolation, segregation, and leprosy are traced, as are their use in or absence from the writings of missionaries, chroniclers, and doctors in Angola and Mozambique as of the second half of the seventeenth century.

The Medicinal Usage and Restriction of Ginseng in Britain and America, 1660-1900.

This article demonstrates the medicinal usage of ginseng in the West from 1660 to 1914. Asian[Korea] ginseng was first introduced into England in the early 17th century, and North American ginseng was found in the early 18th century. Starting from the late 17th century doctors prescribed ginseng to cure many different kinds of ailments and disease such as: fatigue general lethargy, fever, torpidity, trembling in the joints, nervous disorder, laughing and crying hysteria, scurvy, spermatic vessel infection, jaundice, leprosy, dry gripes and constipation, strangury, yellow fever, dysentery, infertility and addictions of alcohol, opium and tobacco, etc. In the mid-18th century Materia Medica began to specify medicinal properties of ginseng and the patent medicines containing ginseng were widely circulated. However, starting in the late 18th century the medicinal properties of ginseng began to be disparaged and major pharmacopoeias removed ginseng from their contents. The reform of the pharmacopoeia, influenced by Linnaeus in botany and Lavoisier in chemistry, introduced nomenclature that emphasized identifying ingredients and active constituents. Western medicine at this period, however, failed to identify and to extract the active constituents of ginseng. Apart from the technical underdevelopment of the period, the medical discourses reveal that the so-called chemical experiment of ginseng were conducted with unqualified materials and without proper differentiation of various species of ginseng.
