Plants in Menstrual Diseases: A Systematic Study from Italian Folk Medicine on Current Approaches.

Background: Plant-based remedies have been used since antiquity to treat menstrual-related diseases (MD). From the late nineteenth to the early to mid-twentieth century, Italian folk remedies to treat "women's diseases" were documented in a vast corpus of literature sources. Aim: The purpose of this paper is to bring to light the plant-based treatments utilized by Italian folk medicine to heal clinical manifestations of premenstrual syndrome (PMS), dysmenorrhea, amenorrhea and menstrual disorders in an attempt to discuss these remedies from a modern pharmacological point of view. Moreover, we compare the medical applications described by Hippocrates with those utilized by Italian folk medicine to check if they result from a sort of continuity of use by over two thousand years. Results: Out of the 54 plants employed in Italian folk medicine, 25 (46.3%) were already documented in the pharmacopoeia of the Corpus Hippocraticum for treating MD. Subsequently, a detailed search of scientific data banks such as Medline and Scopus was undertaken to uncover recent results concerning bioactivities of the plant extracts to treat MD. About 26% of the plants used by Italian folk medicine, nowadays, have undergone human trials to assess their actual efficacy. At the same time, about 41% of these herbal remedies come back to in different countries. Conclusions: Active principles extracted from plants used by Italian folk healers could be a promising source of knowledge and represent strength candidates for future drug discovery for the management of MD.

Characterization of the 2017 Summer Heat Waves and Their Effects on the Population of an Area of Southern Italy.

Knowledge of bioclimatic comfort is paramount for improving people's quality of life. To this purpose, several studies related to climatic comfort/discomfort have been recently published. These studies mainly focus on the analysis of temperature and relative humidity, i.e., the main variables influencing the environmental stress in the human body. In this context, the present work aims to analyze the number of visits to the hospital emergency department made by the inhabitants of the Crati River valley (Calabria region, southern Italy) during the heat waves that accompanied the African anticyclone in the summer of 2017. The analysis of the bioclimatic comfort was performed using the humidity index. Results showed that greater the index, the higher the number of accesses to the emergency department, in particular by the most vulnerable population groups, such as children and the elderly.

A review of the antimicrobial potential of herbal drugs used in popular Italian medicine (1850s-1950s) to treat bacterial skin diseases.

ETHNOPHARMACOLOGICAL RELEVANCE: Before the advent of modern antibiotics, microbial infections were treated with herbal medicine or cauterization. Literature from the latter half of the nineteenth to the early mid-twentieth century, when antibiotics became widely available, arguably holds the most progressive information about herbal remedies to treat bacterial skin diseases. The corpus of literature produced in Italy during that period is not easily accessible and mostly out of print. MATERIAL AND METHODS: Plant-based remedies utilized in popular Italian medicine to treat anthrax, boils, erysipelas, impetigo, pustules, and whitlow were sourced from literature indexed in and available through the National Library Service website of the Italian Libraries Network. The remedies are assessed for their antimicrobial potential based on a detailed search of the herbal drug species in scientific databases. RESULTS: A considerable part of the reviewed recipes included specific excipients (41 out of 139) and others were produced with fresh plant material (48 out of 139). Out of the 52 identified herbal drug species used in popular Italian medicine against dermatologic infections, extracts of 43 were shown to have moderate in vitro activity against Gram-positive and Gram-negative bacteria. CONCLUSION: The antibacterial activity of the extracts and pure compounds as reported in the reviewed literature is mostly based on in vitro assays and generally does not encourage follow up studies. The effectiveness of the reported recipes, which include fresh plant material and excipients can only be assessed through in vivo studies. Those remedies including herbal drugs with reported antimicrobial activity might have the potential as complementary therapies. The reviewed plant based antimicrobial recipes might serve as inspirations in the search for alternative topical antibacterial strategies and the search for their synergistic and potentiating ingredients.

Italian folk plant-based remedies to heal headache (XIX-XX century).

BACKGROUND: Headache has been recognized since antiquity. From the late nineteenth to the early to mid-twentieth century, Italian folk remedies to treat headache were documented in a vast corpus of literature sources. AIM: The purpose of this paper is to bring to light the plant-based treatments utilized by Italian folk medicine to heal headache in an attempt to discuss these remedies from a modern pharmacological point of view. Moreover, we compare the medical applications described by Hippocrates, Pliny the Elder, Dioscorides, Galen and Serenus Sammonicus with those utilized by Italian folk medicine to check if they result from a sort of continuity of use by over two thousand years. RESULTS: A detailed search of the scientific data banks such as Medline and Scopus was undertaken to uncover recent results concerning the anti-inflammatory, anti-nociceptive and analgesic activities of the plants. Fifty-eight (78.4%) plant-based remedies have shown in vivo, in vitro or in human trials a large spectrum of anti-inflammatory, anti-nociceptive and analgesic activities. Moreover, thirty-one of remedies (41.9%) were already included in the pharmacopoeia between the 5th century BC and the 2nd century AD. CONCLUSION: Italian folk medicine could be a promising source of knowledge and could provide evidences for active principles that have not as of yet been fully used for their potential.

Shared language, diverging genetic histories: high-resolution analysis of Y-chromosome variability in Calabrian and Sicilian Arbereshe.

The relationship between genetic and linguistic diversification in human populations has been often explored to interpret some specific issues in human history. The Albanian-speaking minorities of Sicily and Southern Italy (Arbereshe) constitute an important portion of the ethnolinguistic variability of Italy. Their linguistic isolation from neighboring Italian populations and their documented migration history, make such minorities particularly effective for investigating the interplay between cultural, geographic and historical factors. Nevertheless, the extent of Arbereshe genetic relationships with the Balkan homeland and the Italian recipient populations has been only partially investigated. In the present study we address the genetic history of Arbereshe people by combining highly resolved analyses of Y-chromosome lineages and extensive computer simulations. A large set of slow- and fast-evolving molecular markers was typed in different Arbereshe communities from Sicily and Southern Italy (Calabria), as well as in both the putative Balkan source and Italian sink populations. Our results revealed that the considered Arbereshe groups, despite speaking closely related languages and sharing common cultural features, actually experienced diverging genetic histories. The estimated proportions of genetic admixture confirm the tight relationship of Calabrian Arbereshe with modern Albanian populations, in accordance with linguistic hypotheses. On the other hand, population stratification and/or an increased permeability of linguistic and geographic barriers may be hypothesized for Sicilian groups, to account for their partial similarity with Greek populations and their higher levels of local admixture. These processes ultimately resulted in the differential acquisition or preservation of specific paternal lineages by the present-day Arbereshe communities.

From Disease to Holiness: Religious-based health remedies of Italian folk medicine (XIX-XX century).

BACKGROUND: The relationship between spirituality, religion and medicine has been recognized since antiquity. Despite large differences in their history, society, economy and cultures human communities shared a common belief that spirituality and religion played an important role in the healing of diseases. METHODS: The study of religious remedies used by Italian folk medicine in order to treat diseases was based on a review of literature sources compiled between the late nineteenth century and the early to mid twentieth century. RESULTS: This approach lead to the unearthing of heterogeneous healing methods that have been divided into different categories: Saints, Pilgrimages, Holy Water/Blessed Oil, Blessings, Religious Objects, Contact, Signs, Formulas and The Religious Calendar. Some of these practices, partly still performed in Italy, are a part of the landscape of the official Catholic Church, others come out of a process of syncretism between the Catholic Religion, the magic world and pre-Christian rituals. CONCLUSIONS: The vastus corpus of religious remedies, highlighted in the present work, shows the need for spirituality of the sick and represent a symbolic framework, that works as a filter, mediates, containing the pain that constantly fills everyone's lives in remote ages even in the third millennium. All of this confirms how important the health-workers know and interpret these existential needs from anthropological and psychological points of view.

Linguistic, geographic and genetic isolation: a collaborative study of Italian populations.

The animal and plant biodiversity of the Italian territory is known to be one of the richest in the Mediterranean basin and Europe as a whole, but does the genetic diversity of extant human populations show a comparable pattern? According to a number of studies, the genetic structure of Italian populations retains the signatures of complex peopling processes which took place from the Paleolithic to modern era. Although the observed patterns highlight a remarkable degree of genetic heterogeneity, they do not, however, take into account an important source of variation. In fact, Italy is home to numerous ethnolinguistic minorities which have yet to be studied systematically. Due to their difference in geographical origin and demographic history, such groups not only signal the cultural and social diversity of our country, but they are also potential contributors to its bio-anthropological heterogeneity. To fill this gap, research groups from four Italian Universities (Bologna, Cagliari, Pisa and Roma Sapienza) started a collaborative study in 2007, which was funded by the Italian Ministry of Education, University and Research and received partial support by the Istituto Italiano di Antropologia. In this paper, we present an account of the results obtained in the course of this initiative. Four case-studies relative to linguistic minorities from the Eastern Alps, Sardinia, Apennines and Southern Italy are first described and discussed, focusing on their micro-evolutionary and anthropological implications. Thereafter, we present the results of a systematic analysis of the relations between linguistic, geographic and genetic isolation. Integrating the data obtained in the course of the long-term study with literature and unpublished results on Italian populations, we show that a combination of linguistic and geographic factors is probably responsible for the presence of the most robust signatures of genetic isolation. Finally, we evaluate the magnitude of the diversity of Italian populations in the European context. The human genetic diversity of our country was found to be greater than observed throughout the continent at short (0-200 km) and intermediate (700-800km) distances, and accounted for most of the highest values of genetic distances observed at all geographic ranges. Interestingly, an important contribution to this pattern comes from the "linguistic islands"( e.g. German speaking groups of Sappada and Luserna from the Eastern Italian Alps), further proof of the importance of considering social and cultural factors when studying human genetic variation.

Treating epilepsy in Italy between XIX and XX century.

Epilepsy is a neurological disorder which has been recognized since antiquity. This paper evaluates the prophylactic and therapeutic remedies used by folk medicine to cure epilepsy in Italy. The data has been collected by reviewing written sources of physicians, ethnographers, folklorists between the late nineteenth and mid twentieth century. This approach leads to unearthing of 78 heterogeneous healing methods that have been divided into 16 (20%) magical, 20 (26%) religious and 42 (54%) natural remedies. The latter has been subdivided into 18 (43%) animal remedies, 17 (40%) plant remedies and 7 (17%) other remedies. Religious and magical remedies were used with the conviction that they would be able to provide recovery from epilepsy and to ward off evil spirits which had taken possession of the sick. Interestingly, the herbal remedies highlighted 12 (70%) plants that play or might play an important role with respect to the mechanisms that generate the epileptic seizures. This leads us to reconsider the historical significance of folk medicine, too often it is underestimated owing to its use of ineffective remedies, born of incompetence and superstition.

A brief history of syphilis by its synonyms.

The history of a disease can be described or revisited by different main roads analyzing archival documents or rich bibliography, or studying biographies of different renowned men. Other different main roads can be apparently less important, too. These can be described as studying different therapies, renowned affected men or synonyms for diseases. We choose this latter main road studying the syphilis disease by the historical course of its numerous different synonyms during five centuries.

Linking Italy and the Balkans. A Y-chromosome perspective from the Arbereshe of Calabria.

BACKGROUND: The Arbereshe are an Albanian-speaking ethno-linguistic minority who settled in Calabria (southern Italy) about five centuries ago. AIM: This study aims to clarify the genetic relationships between Italy and the Balkans through analysis of Y-chromosome variability in a peculiar case study, the Arbereshe. SUBJECT AND METHODS: Founder surnames were used as a means to identify a sample of individuals that might trace back to the Albanians at the time of their establishment in Italy. These results were compared with data of more than 1000 individuals from Italy and the Balkans. RESULTS: The distributions of haplogroups (defined using 31 UEPs) and haplotypes (12 STRs) show that the Italian and Balkan populations are clearly divergent from each other. Within this genetic landscape, the Arbereshe are characterized by two peculiarities: (a) they are a clear outlier in the Italian genetic background, showing a strong genetic affinity with southern Balkans populations; and (b) they retain a high degree of genetic diversity. CONCLUSION: These results support the hypothesis that the surname-chosen Arbereshe are representative of the Y-chromosome genetic variability of the Albanian founder population. Accordingly, the Arbereshe genetic structure can contribute to the interpretation of the recent biological history of the southern Balkans. Intra-haplogroup analyses suggest that this area may have experienced important changes in the last five centuries, resulting in a marked increase in the frequency of haplogroups I2a and J2.

Casimir Funk: his discovery of the vitamins and their deficiency disorders.

The history of the discovery of vitamins is the history of their deficiency disorders. Their discoverer was Casimir Funk, who is considered the 'father of vitamin therapy'. In his experimental research, Funk studied the interrelationships in the human body of those elements that Eijkman had demonstrated in animals, particularly in birds. In his experimental research, Funk identified the dietetic factors whose lack caused the 'deficiency disorders', as he called human beri-beri, scurvy, rickets and pellagra. In 1911, he designated these factors 'vitamins' ('vita' = life, and 'amine' = a nitrogenous substance essential for life); this name was accepted by the scientific community in 1912.

Folk medicine used to heal malaria in Calabria (southern Italy).

In Italy, malaria was an endemic disease that was eradicated by the mid-20th century. This paper evaluates the prophylactic and therapeutic remedies used by folk medicine to cure malaria in Calabria (southern Italy).The data has been collected by analysing works of physicians, ethnographers, folklorists and specialists of the study of Calabrian history between the end of the 19th century and the 20th century. The data collected have allowed us to describe the most common cures used by the Calabrian people to treat malaria and the most evident symptoms of this disease, such as intermittent fever, hepato-spleenomegaly, asthenia and dropsy. This approach uncovered a heterogeneous corpus of empirical, magical and religious remedies, which the authors have investigated as evidences of past "expert medicine" and to verify their real effectiveness in the treatment of malaria.

Paul Ehrlich: the Nobel Prize in physiology or medicine 1908.

We wish to commemorate Paul Ehrlich on the centennial of his being awarded the Nobel Prize in Physiology or Medicine in 1908. His studies are now considered as milestones in immunology: the morphology of leukocytes; his side-chain theory where he defined the cellular receptor for first time; and his clarification of the difference between serum therapy and chemotherapy. Ehrlich also invented the first chemotherapeutic drug: compound 606, or Salvarsan. We have used some original documents from the Royal Society of London, where Ehrlich was a fellow, and from Leipzig University, where he took a degree in medicine.

Ethnicity and biodemographic structure in the Arbëreshe of the province of Cosenza, southern Italy, in the XIX century.

Cultural and environmental factors interact in determining the genetic structure of human populations. Bio-demographic investigations of ethnic minorities are able to disentangle the influences that these two components have on the evolution of the genetic structure of a population. The ethnic minority of the Arbëreshe of the province of Cosenza (Calabria, southern Italy) is analyzed in this paper and its bio-demographic structure in the early 1800s is compared with that of neighboring Italian populations. The data derive from surnames recorded in the birth registers of the 19 Arbdreshe municipalities of the province of Cosenza and in 5 non-Arbëreshe municipalities of the same province. Isonymy and repeated pairs of surnames are used to analyze the bio-demographic structure of these populations, while analysis of isonymic relationships is used to investigate the variability between populations. Higher values of marital isonymy and subdivision into subpopulations characterize the Arbëreshe populations with respect to their non-Arbëreshe neighbors. However, the high range of variability of these parameters suggests a strong influence of geographic location on the marriage pattern of each community. At the same time, cultural differences linked to group identity had a strong impact in limiting marriage exchanges between the different ethnic groups living in the province of Cosenza in the early 1800s. In fact, the analysis of isonymic relationships demonstrates that geographic location shaped kinship patterns among the Arbereshe communities, but it also shows that the non-Arbëreshe neighbors formed a clearly separate reproductive cluster.
