Malaria as a Papal Disease.

OBJECTIVES: In this study, we aimed to investigate the effects of malaria on the lives of Roman pontiffs. MATERIALS AND METHODS: The histories of all 264 popes from Saint Peter to John Paul II were extensively studied. RESULTS: Malaria affected the lives of Roman pontiffs. Between 999 AD and 1644 AD, 21 of 99 popes were affected by malaria (21.4%). The first affected was Gregory V and the last was Urban VII, the 138th and the 235th pope, respectively. There were 15 deaths (15.2%). Six pontiffs (6.1%) were infected but survived. Many cardinals and their assistants, especially those coming from northern countries, contracted malaria during conclaves, and many died. CONCLUSIONS: By about 450 BC, malaria had arrived in Rome. By the second century BC, malaria was endemic. It affected the lives of Roman people. To prevent infection, the popes adopted the custom of ancient affluent Romans who used to spend summer months in high plains far from Rome. The first to adopt the custom was Paul I in 767, who just moved his residence to Saint Paul, out of the walls. Sixtus V started the Congregation of Waters and Streets, which was routinely reinforced by his successors until 1860, when the Kingdom of Italy was born.

Acute Kidney Injury as a Leading Cause of Papal Deaths in the Years 1277 to 2005: A Review of 21 Cases.

OBJECTIVES: This study was devised to investigate papal deaths due to acute kidney injury, a topic for which scarce data exist. MATERIALS AND METHODS: We studied all popes between John XXI, who died in 1277 of crush syndrome, and John Paul II, who died of anuria and urinary sepsis in 2005. RESULTS: Between pontification years from 1277 to 2005, 21 of 78 popes (26.9%) died of acute kidney injury. Sepsis was identified as the leading cause of acute kidney injury and death in 20 of 21 popes (95.2%). Mean ± SE age at death of the 21 popes was 69.4 ± 2.26 years. Six popes (28.6%) died of stroke. CONCLUSIONS: Sepsis-associated acute kidney injury, a syndrome with a complex pathogenesis and poor prognosis, which is far from being fully understood, contributed to a high number of papal deaths.

High Prevalence of Kidney Stone Disease of Gouty Origin in Roman Pontiffs Reigning in the Years 537-2005.

OBJECTIVES: Many Roman pontiffs are known to have had kidney stone disease. However, no specific report has explored the prevalence of the various stones in popes, which is the purpose of this study. MATERIALS AND METHODS: We extensively studied the histories of all popes (n = 264) from Saint Peter to John Paul II (34-2005). RESULTS: Among 206 popes reigning from 537 to 2005, 26 popes (12.6%) had uric acid stones. In the same period, 11 of 206 popes (5.3%) had nongouty stones (mainly calcium stones). In total, 37 of 208 (17.8%) popes complained of kidney stone disease. The ratio of calcium stone formers to other stone formers (including uric acid) was 0.42. CONCLUSIONS: The data suggest a higher prevalence of uric acid stones, which is linked to higher consumption of meat and sodium chloride. However, the last pope with kidney stone disease died in 1914. Although renal stone disease disappeared from papal palaces, population studies now indicate an increase in uric acid levels in the general population. The data can be explained based on the "Theory of Epidemiological Transition," pointing to the importance of education in eradicating poor lifestyles.

The Dropsy of Popes (1555-1978): A Bad Prognostic Sign Foreboding of Death.

The purpose of this study is to explore the historical background of edema as a prognostic sign in popes, a special category of medical subjects whose health status was closely monitored and chronicled because of their unique important status in the events of their times. Nine out of 51 popes, who reigned in the years 1555-1978, died edematous at a mean age of 75.5 years of age. The cause of edema was: heart failure for John Paul I, liver disease, obstructive nephropathy associated with anemia for Paul IV, who also suffered from deep vein thrombosis, and malnutrition for Innocent XIII. Chronic kidney disease due to renal stones of gouty origin caused edema in Clement VIII, Clement X, Clement XI, and Benedict XIV. Obstructive nephropathy due to renal stones of non-gouty origin caused edema in Clement XIII, whereas toxic nephropathy due to the use of mercurials caused edema in Clement XIV. Innocent XI, Benedict XIV, and Clement XIV were bled before death because of impending pulmonary edema. It is not surprising that chronic kidney disease was a significant cause of edema in popes with chronic kidney disease which is associated with impaired sodium excretion. The edema was likely aggravated by the excessive dietary salt intake of the period when the importance of sodium chloride restriction was still not discovered and effective diuretic agents were not available.

Pius X (1835-1914): the last gouty pope.

Gout is a common, complex, systemic and well-studied form of chronic inflammatory arthritis in adults. It is due to the deposition of sodium monourate crystals in peripheral joints and periarticular tissues driven by hyperuricemia. Gout is the oldest recorded inflammatory arthritis to affect humankind, with roots stretching back to 2460 BC. It is known as "the rich man's disease", "the patrician malady", "a disease of plenty", "disease of kings", "disease of Western Society", and also "a life-style disease". Few studies have addressed the problem of gout among popes, affluent people who usually live longer than their contemporaries and are among the most scrutinized persons. Pius X (1835-1914) was the last pope with gout. Gout seems to have affected 26 out of 265 popes (9.81%) from Saint Peter to Benedict XVI (34-2013 AD). The first was Gregory I Magnus, who was pope in the years 590-604, the last was Pius X, who reigned from 1903 to 1914 at age 79. Their age at death was 71.7 ±9.2 years (Mean ± SD). All popes were elderly men, some had voracious appetites and/or were wine drinkers. Several were sedentary and obese, while others were sober eaters, who took long walks or went riding. Chiragra (arthritic pain in the hands), podagra (arthritic pain in the big toe) and renal stone disease were among the most frequent disturbances. The causes of death, due to CKD, strokes and infections are discussed along with the fact that gout disappeared from the Vatican Palace on August 22, 1914. However, in accordance with the Theory of Epidemiological Transition, gout seems likely to become a problem for the general population, increasingly adopting unhealthy lifestyle choices, in the absence of a correct education.

Regulation of urinary calcium excretion by vasopressin.

BACKGROUND: The antidiuretic hormone (ADH) or arginine vasopressin (AVP) regulates the body's water balance. Recently, modifications in AVP levels have been related to osteoporosis during ageing and microgravity/bed rest. Therefore the present study was devised to assess whether the absence of AVP, as in patients with central diabetes insipidus (CDI), modulates renal calcium excretion. METHODS: We retrospectively analysed data from 12 patients with CDI with measured 24-h urinary excretion levels of calcium. Data were available at the moment of the diagnosis when patients were drug-free and after therapy with dDAVP, an analog of AVP. Hypercalciuria was defined as 24-h urinary Ca2+ >275 mg/day in males and >250 mg/day in females and a urinary calcium (Ca):creatinine (Cr) ratio >0.20 mg/mg. RESULTS: Untreated CDI patients had a daily urinary Ca2+ excretion of 383 ± 47 mg/day and a urinary Ca:Cr ratio of 0.26 ± 0.38 mg/mg. The urine osmolarity significantly increased after the administration of dDAVP by 210% and the urinary flow decreased by 72%. Furthermore, the estimated glomerular filtration rate (eGFR) increased by 7%, which did not reach statistical significance. dDAVP treatment did not significantly modify the urinary Ca2+ concentration; however, the daily calcium excretion and the urinary Ca:Cr ratio were significantly decreased (160 ± 27 mg/day and 0.11 ± 0.02 mg/mg, respectively). CONCLUSIONS: Patients with CDI show hypercalciuria even though urine is more diluted than normal controls, and dDAVP reverses this effect. These data support the intriguing relationship between AVP and osteoporosis in ageing and microgravity/bed rest.

Legislative proposal in Italy to facilitate contacts between deceased organ donor families and transplant recipients.

Contacts between organ donors and recipients might be possible in the near future in Italy. As suggested by The Italian Committee of Bioethics "anonymity is requested by the Italian National Transplant Centre" before transplantation anonymity shall be strict in order to grant privacy, gratuity, justice, solidarity and benefits and avoids organ trafficking. Following a period that is ethically correct and justifiable, organ donor families and recipients can meet after signing a valid declaration of consent, expressed on a template valid for the whole country. A third party within the body of the National Health Systems shall control the validity of the consent. The opinion stresses that contacts are not a right but a possibility justifiable on ethical grounds if the procedure is followed appropriately. A legislative proposal has been presented before the Chamber of deputies incorporating all suggestions made by the National Committee of Bioethics. The agreement between parties might be signed a year after transplantation. This is a long enough period of time for the recipients to fully appreciate the benefits of the procedure and for the donor families to see the effects of their decision (the opinion and the Law proposal hit the Zeitgeist, and keep Italy in the regulation of European Union).

Comparison between men and women of volume regulating hormones and aquaporin-2 excretion following graded central hypovolemia.

Central hypovolemia induced by orthostatic loading causes reno-vascular changes that can lead to orthostatic intolerance. In this study, we investigated volume regulating hormonal responses and reno-vascular changes in male and female subjects as they underwent central hypovolemia, induced by graded lower body negative pressure (LBNP). Aquaporin-2 (AQP2) excretion was measured as a biomarker for the renal system response to vasopressin. 37 young healthy subjects (n = 19 males; n = 18 females) were subjected to graded LBNP until - 40 mmHg LBNP. Under resting conditions, males had significantly higher copeptin (a stable peptide derived from vasopressin) levels compared with females. Adrenocorticotropin (ACTH), adrenomedullin (ADM), vasopressin (AVP) and brain natriuretic peptide (BNP) were not affected by our experimental protocol. Nevertheless, an analysis of ADM and BNP with the data normalized as percentages of the baseline value data showed an increase from baseline to 10 min after recovery in the males in ADM and in the females in BNP. Analysis of BNP and ADM raises the possibility of a preferential adaptive vascular response to central hypovolemia in males as shown by the normalized increase in ADM, whereas females showed a preferential renal response as shown by the normalized increase in BNP. Furthermore, our results suggest that there might be a difference between men and women in the copeptin response to alterations in orthostatic loading, simulated either using LBNP or during posture changes.

Maximum Time-to-Rescue After the 1908 Messina-Reggio Calabria Earthquake was 20 Days: Hints for Disaster Planning?

Introduction Maximum time-to-rescue has been studied accurately for many earthquakes in the years 1985-2004. No study is available for historical quakes. Hypothesis/Problem This study aimed to evaluate long-term survivors (from the fifth day after the quake) of the Messina-Reggio Calabria earthquake (1908; Italy), which is considered, historically, to be the worst seismic event in Europe. METHODS: Accurate readings of 11 national newspapers from the fifth day after the quake looking for rescued persons and transferring, to an ad hoc form, all data relating to each rescued person. RESULTS: The maximum time-to rescue was 20 days. There were 225 survivors, among them 51 children (22.6 %). For 23 out 225 rescued persons, there was evidence of availability of foods and drinkable fluids while under the rubble. CONCLUSION: The maximum time-to-rescue under the debris following this historical earthquake far exceeds that of all other quakes that occurred in the years 1985-2004. The long survival under debris was probably due to the lack of an order to stop search and rescue. Recent strategies reducing the time for search and rescue carry the risk of missing survivors.

The priority of Antonino D'Antona in describing rhabdomyolysis with acute kidney injury, following the Messina earthquake (December 28, 1908). Commentary.

Following the Messina-Reggio Calabria earthquake (December 28, 1908) outstanding medical reports were published by Franz von Colmers (1875-1960), Antonino D'Antona (1842-1913), and Rocco Caminiti (1868-1940). The reports of D'Antona and Caminiti were heretofore neglected. Colmers, D'Antona and Caminiti described crush-syndrome. D'Antona who cured patients in shock also described two deaths due to uraemia. This gives him a priority in the description of crush syndrome with renal injury which has been traditionally attributed to Bywaters and Beall.

Antonino D'Antona (1842-1913) was the first in describing the crush syndrome with renal failure following the Messina earthquake of December 28, 1908.

There is confusion about the first description of the association between crush syndrome and renal failure. It has been traditionally attributed to Bywaters and Beall. The present study aims to analyze the problem by analyzing medical reports on the Messina-Reggio Calabria earth-quake of December 28, 1908 by using documents heretofore unknown. It demonstrates that first description of rabdomyolysis with renal failure is attributed to Antonino DAntona (1842- 1913). DAntona, professor of surgery at the University of Naples, coordinated the health net organized in Naples to assist persons wounded during the quake. Many of them in shock were transferred to Naples by ships. Franz von Colmers (1875-1960) was the chief surgeon of the German Mission of the Red Cross after the quake. Because his late arrival, he did not treat patients with shock. He described rabdomyolysis. The third medical report is that of Rocco Caminiti (1868-1946), collaborator of DAntona at the University of Naples, and chief of surgery at the Loreto Hospital. He directed a rescue group in Villa San Giovanni and Reggio Calabria. In 1910, he reported on rabdomyolysis in patients treated in the place of the disaster. Therefore the present study indicates that Antonino DAntona holds the priority for description of rabdomyolysis and kidney injury. There is no longer a place for the eponym Bywaters syndrome.

Diuretic plants in the Bible: ethnobotanical aspects.

Besides its religious importance, the Bible, because of its ancient origin represents a relevant witness of the way of life of the people mentioned in it. The Holy Scripture is also the first text revealing the utility of plants for man, as natural sources of food, wood, fibers, oils and medicinal herbs. In the last 60 years, several distinguished botanists have attempted to identify the scientific names of the plants cited in the Bible. Nonetheless, these scholars have provided different lists of plants appearing in the Bible, none of which could be accepted as indisputable. The authors have combined their expertise to focus on the identification of the diuretic plants, through an historical analysis of the literature on this issue.

Jacques Loeb (1859-1924) and His Forgotten Contributions to Electrolyte and Acid-Base Physiology in The Organism as a Whole.

Jacques Loeb (1859-1924) was the founder of the Journal of General Physiology which he co-directed in association with W.J.V. Osterhout in the years 1918-1924. Having worked (1889-1891)at the Marine Zoological Station of Naples, newly founded by Anton Dohrn, he was imprinted for life. A strong investigator used to perform the experiments personally. Loeb was engaged lifelong in the explanation of life on physico-chemical basis. He touched various fields (being a creative scientist full of ideas), and centered on the exchanges of electrolytes, acids and bases between the body and sea water in fish. He identified two equations: {[K+]+[Na+]}: {[Ca++]+[Mg++]} (Loebs 1st equation) {[K+]+[Na+]}: {[H+]+[Ca++]+[Mg++]} (Loebs final equation) Even nowadays these equations may have applications in a wide list of electrolyte and acid-base disturbances. Unfortunately his heredity has been dissipated.

Disease of the kidney and of the urinary tract in De Medicina Methodica (Padua, 1611) of Prospero Alpini (1563-1616).

AIM: The study was devised to understand the contribution to nephrology ofDe Medicina Methodicaof Prospero Alpini published in 1511, at a time when the fame of the professor reached the azimuth. METHOD: We have analyzed the contents of chapters devoted to nephrology in that book of Prospero Alpini and the novelties of his message. RESULTS: Prospero Alpini (1563-1616) taught at the University of Padua (1594-1616), at the same time of Galileo Galilei, Santorio Santorio, and Girolamo Fabrizi dAcquapendente, when measurements (pulse, temperature, perspiration) were introduced into medicine. He was a travelling physician to whom we owe fundamental contributions to the use of urine to prognosticate life and death (De Praesagienda vita et morte aegrotantium libri septem, Venetiis, apud Haeredes Melchioris Sessae,1601). As prefect of the Botanical Garden - the first ever and a model in the world - he could turn the study of simples into cures(De Medicina Methodica Libri Tredecim. Patavi, apud Franciscum Bolzettam, 1611. Ex typographia Laurentij Pasquali, is anin foliovolume of XLVII + 424 pages, 54 lines per page), wherein Alpini aimed to rejuvenate antique medical Methodism. It is a testimony of the interest of medicine philosophers of the modern era for the corpuscular and atomic ideas (Nancy Siraisi). Methodists (2ndCentury BC) refused anatomy and physiology as unique guidelines to the interpretations of diseases and gave importance to the development of a pharmacological science and alternative medicine. The book begins with a 3 page letter to Francis Maria della Rovere Duke of Montefeltro, and a 2 page letter to the readers. We discuss the novelties of the chapters on renal colic (de dolorerenum), hematuria (de sanguinis profluvium), pyuria, anuria (de urina suppressa) and its cure, polyuria (de urina profluvio), renal abscesses, hydrops and its treatment by skin incisions. We also analyze the chapter on kidney and bladder stones (Book X, Chapter XVIII, pp. 354-356) - a masterpiece of scholarly teaching - encompassing localization of stones, their formation and shape, renal colic and its irradiation according to the site and gender, the best antalgic position to pass stones, the use of laxatives, cathartics, warm baths, the plants to be used, their preparation and quality, the waters to be drank and their quantity (up to 15 pounds a day), the removal of bladder stones without surgery (methods learned in Cairo and described in Aegyptyan Medicine), and lithotomy and its feasibility even in old people. CONCLUSION: De Medicina Methodicawas a modern monograph devoted to clinical medicine including urinary disease. The book reflected the polyhedral personality of the author, his experience as physician of the Republic of Venice at Cairo, and his capabilities as a director of the Botanical Garden of the University of Padua, a unique research centre in those times.
