NOTE:  In 2014  Pavlos Plessas presented the compelling theory that Andreas Vesalius died in 1564 from scurvy on the island of Zakynthos. With his permission his original article entitled "Powerful indications that Vesalius died from scurvy" was published in this blog in 2016.

His theory was later challenged by Theo Dirix and Dr. Rudi Coninx in this same blog with the article "Did Andreas Vesalius really died from scurvy?". Pavlos Plessas' rebuttal to the latter article is published here from a letter to Theo Dirix.

Three years after my 2014 speech at the Vesalius Continuum meeting, where I suggested that scurvy appeared as the only possible explanation to Vesalius’ death, Dr. Rudi Coninx and Theo Dirix published a refutation. Theo is a dear friend and Dr. Coninx has dealt with scorbutic patients in Ethiopia. In addition, Theo is – along with another good friend, Pascale Pollier – the driving force behind the search for Vesalius’ remains. Arguments are always welcome, since they bring us closer to the truth, and are particularly important amongst people with common goals. Here is my reaction.

Quotes have been altered or truncated for brevity.

1. Vesalius must have eaten well in the Holy Land because he was a nobleman

The point I made was that at that time of year there was extreme scarcity of foods containing Vitamin C in that area, not that Vesalius was devoid of means or that he was not well looked after by the monks who hosted him.

2. Vesalius ate the food that protected monks from scurvy

3. Scurvy was not uncommon in the area but people were not dying in large numbers

If they had been suddenly forced to migrate en masse, through desert and sea for three months in Vesalius’ footsteps, there would have been a very large number of deaths.

4. Liver and kidneys are also sources of Vitamin C

True, but they are not prime cuts. How many times a month would a nobleman be offered offal? I would say probably none.

5. Forty days at sea is not long enough to develop scurvy. Symptoms appear after 3 months at least

This is true for a previously healthy-eating subject of a study. An 18th century British warship could easily have a dozen dead and another 50 sick in less than 2 months (2) . There are many factors such as activity, infections, temperature, stress, smoking and possibly others, like age, gender, weight and genetic make-up. The most important though is the amount of Vitamin C in the body when the period of deprivation starts. Some historians seem to believe that West European aristocrats would not have fared very well in this field because of their diet. There is an intriguing study by Susan Maclean Kybett that suggests Henry VIII of England, a contemporary of Vesalius, died from scurvy. And he was neither in the Middle East nor at sea. Vesalius had been travelling for seven months prior to his death. Of those, more than two he spent at sea and more than three in arid conditions during the summer. This is how and where he spent the last five months of his life. He could have been affected by scurvy and died even earlier than he did.

6. “Clinical description is typical for scurvy”. This is simply not true

What is not true is that I ever made the above statement. I am not a doctor and I did not make a diagnosis. I presented a theory based on historical research. What I said is that every single thing we know about this case, not only the few symptoms known to us, either points to scurvy or is compatible with scurvy. At the same time no other illness fits the picture. I also made two more observations. First that the sources, which do not name the disease – scurvy had no universally accepted name yet – and do not consciously describe its symptoms, do give a number of causes for it, all of which feature in a list of causes of scurvy in the treatise of Johannes Echtius. Second that the fact Echtius took the trouble to meet Georgius Boucherus – the man who travelled with Vesalius and paid for his burial – and hear for himself the details of what happened is probably not coincidental.

7. Vesalius would have recognized the symptoms of scurvy and described them

We have no description of the disease or its symptoms by Vesalius. There is no reason to believe that Vesalius would have described symptoms of scurvy but not of the plague or of cholera for example. All sources are unfortunately silent on the symptoms. His mental state and his sudden death were only mentioned because they were unusual and impressive events, and in the case of the former also as a factor that contributed to his illness. I am the one who considers them as symptoms of an illness.

The "Canal of Nuck" is the patent embryological remnant of the processus vaginalis in the female. The processus vaginalis is an extension of the peritoneum that forms to the side of the gubernaculum, a small fibrous cord that is attached to the lower pole of the gonad in the embryo. On the other end, the gubernaculum attaches to the inner aspect of the labioscrotal fold, an embryonic structure that will become the scrotum in the male and the labia majora in the female.

In the male, the processus vaginalis accompanies the gubernaculum and the testicle, on its descent towards the scrotum. In the female, the gonad (ovary) stays in the pelvis and the embryological remnants of the gubernaculum become the proper ovarian ligament (uteroovarian ligament) and the round ligament of the uterus which enters the inguinal canal, splits into multiple small fibers that disappear in the tissues of the labium majus.

In the male (and female) the walls of the processus vaginalis normally fuse, closing the communication between the scrotum (and the labia majora) and the main peritoneal cavity. If they remain open, the name is different, although the pathological consequences are similar (hernia, cysts or hydrocele). In the male, it is called a “patent processus vaginalis”, and in the female it is called the “Canal of Nuck”, which is found patent in 10-20% of the cases, although its presence does not per se imply the presence of pathology.

It was first described by Anton Nuck, a Dutch surgeon and anatomist (1650-1692) in his book "Adenographia & uteri anatome nova" published in 1722. In this book he questions why do some females present with inguinal hernias: "Haecce , praeter alias herniarium species , in utroque sexu obvias auditoribus meis anno fuperiori demonftrandi , difficile vifum fuit explicare , qui Hernia foeminarum inguinales orirentur?" Why when it is easy to see (the canal) in other species it is so difficult to explain to those listening why only some women have inguinal hernias?

In figure XL of the same book he proceeds to show the open processus vaginalis which was from then on known as the eponymic "Canal of Nuck"

Did Andreas Vesalius really die from scurvy on the island of Zakynthos in 1564?
Evidence does not support this theory.

NOTE:  The following article authored by Theo Dirix, and Dr. Rudi Coninx, is a rebuttal of Pavlos Plessas' theory that Andreas Vesalius indeed died from scurvy. The original article entitled "Powerful indications that Vesalius died from scurvy" by Pavlos Plessas was presented in a meeting at the island of Zakynthos in 2014.

...continued...

4. The sudden death

Vesalius did indeed die upon arrival in Zakynthos. And sudden death is indeed associated with scurvy.

We know this from two accounts. Both are second hand accounts:
The Italian Pietro Bizzari based his account on what he had been told by an anonymous Venetian goldsmith. The goldsmith claimed that he had happened upon the sick Vesalius by chance on a deserted beach and, in spite of the opposition he had faced from the Zakynthians, had tried to assist him in his final hours and had buried him with his own hands in a plot he had purchased for that purpose. This account suggests the Vesalius’ death was not sudden, but was prolonged process, lasting at least hours, if not days. None of the typical scurvy signs like the bleeding and joint pain, the foul mouth, are mentioned in the account.

The second written account has come to us via Johannes Metellus, the Latinised name of a Frenchman named Jean Matal. Metellus claims to have received this information from a German traveller from Nuremberg named Georg Boucher. Boucher travelled on the same ship with Vesalius to Zakynthos.

Dr. Rudi Coninx, and Theo Dirix, authors of this article

Metellus describes the symptoms of Vesalius’ illness and they do not match the description of a scorbutic patient. The disease described by Metellus includes symptoms of extreme fear and irrational behaviour, immediately prior to his illness. These are not well known scurvy symptoms, as sometimes is claimed.

Metellus attributes the illness that broke out on Vesalius’ ship, at least partly, to food and water shortages. He is clear though in that the deaths were caused by illness and not directly by starvation or dehydration. Not everyone of the ship was affected. Boucher, for example, does not appear to have fallen ill at any point, despite having had to share the same food as other passengers. The possibility of rotten food as a cause of death on the ship is plausible.

The behaviour changes described by Metellus are sometimes given as proof of scurvy, and reference is made to a 1971 study by Kinsman and Hood [16] which allegedly claims that personality changes are amongst the first symptoms of scurvy.
However, this study was done on only five volunteer prisoners. Not a big sample and certainly not a sample representative of a general population, especially when making conclusions about personality disorders which, moreover are based on answering a questionnaire, not based on observation. In addition, the quoted personality changes appear related to the body pool of ascorbic acid, but the peak appears on day 107. Certainly not an early symptom. And finally, the authors admit that these signs are not specific for vitamin C deficiency: “elevation of this triad is also found in prolonged semi starvation, and deficiencies of B-complex vitamins. These changes are characteristic of individuals who are physically ill, as the subjects were”. 

5. Burial on Zakynthos.

We know that Vesalius died in Zakynthos and was buried there as his tombstone has been described by several contemperous travellers. The German traveller Christoph Fürer Von Haimendorff visited the island in 1565, just a year after Vesalius’ death, and described Vesalius’ grave in the Franciscan monastery of Santa Maria delle Grazie. Von Haimendorff provided us with the details of the burial inscription. In 1586 the tombstone had disappeared, looted in the Turkish attack of 1571, according to Giovanni Zuallardo (Johannes Schwallart), a compatriot of Vesalius, who visited Zakynthos in 1586.

We conclude that the death from scurvy theory, while not entirely implausible, is not backed up by facts. The symptoms attributed to Andreas Vesalius prior to his death simply do not correspond to scurvy. While his altered mental state and his sudden death are compatible with scurvy, the absence of typical tell-tale signs of scurvy (gingival bleeding, joint pain, ecchymoses,) which were known at the time, would certainly have attracted the attention of Vesalius, one of the most prominent doctors of his era. The two remaining signs -altered mental state and his sudden death- are non-specific and are consistent with many other diseases. We therefore agree with the conclusion recently advanced by three eminent Vesalius experts (M. Biesbrouck, Th. Goddeeris and O. Steeno) that Vesalius died from exhaustion combined by illness [17].

In order to have a definite diagnosis, it will be important to locate the grave of Andreas Vesalius, find the remaining bones and test them for signs of scurvy. X-ray changes to the long bones are typical for scurvy [18] and even in adults one should be able to find signs of osteopenia, pathological fractures or others.

This would provide a definitive diagnosis of scurvy, even 500 years after the death of the great anatomist.

Did Andreas Vesalius really die from scurvy on the island of Zakynthos in 1564?
Evidence does not support this theory.

NOTE:  The following article authored by Theo Dirix, and Dr. Rudi Coninx, is a rebuttal of Pavlos Plessas' theory that Andreas Vesalius indeed died from scurvy. The original article entitled "Powerful indications that Vesalius died from scurvy" by Pavlos Plessas was presented in a meeting at the island of Zakynthos in 2014.

...continued...

We believe the arguments in favour of scurvy unfortunately are not sufficient to draw a conclusion. And for each of the argument in favour of the scurvy theory, there are strong counterarguments too.

We will examine the main arguments here

1. Travelers to the Holy Land did have not enough food to eat that contained vitamin C.

There is no evidence that Vesalius, a man of means with introduction letters from the King of Spain, was deprived of food during his travels in the Holy Land. He could certainly buy food, and probably stayed at monasteries, sharing the same food that protected the residing monks from developing scurvy. And while scurvy was not uncommon, residents did not die in large numbers because of lack of vitamin C. Dying from scurvy was, even then, was limited to a small segment of the population.

Minimal daily intake of vitamin C for an adult is 90 mg per day [aa]. Most of that intake comes from fruits and vegetables (oranges, grapefruits …) but liver and kidney are also sources of vitamin C. These are all foods that Vesalius would have consumed in Jerusalem.

Dr. Rudi Coninx, and Theo Dirix, authors of this article

The sea voyage is too short (40 days) to develop scurvy. It takes about three months (120 days) for scurvy to develop [8]. In one study it took healthy volunteers four months to develop signs of scurvy when fed a vitamin C deprived diet [9] although some showed signs at day 29. The first sign to appear was petechial haemorrhage. In 1939, Johan Crandon, a surgical resident at Boston City Hospital, experimented on himself by eating a diet totally devoid of vitamin C [x]. Fatigue developed after 3 to 4 months, and the pathognomonic hyperkeratotic papules appeared on day 134 and the perifollicular haemorrhages on the legs on day 162. Symptoms appear after 3 to 4 months only, and there is no evidence of this in any description of Vesalius symptoms.

It has also been argued that the trip through the Sinai desert must have contributed to the presumed low intake of vitamin C. 
Vesalius’s entire stay in the Holy Land, including the Sinai desert trip –presumably lasting a month and a half- did not last for more than 4 months: he arrived in Jerusalem in May 1564 and boarded ship in Alexandria in September 1564. We believe this is not long enough to deplete all vitamin C and cause symptoms, even adding a 40 day sea voyage. And it is unlikely that his stay in Jerusalem was entirely free of vitamin C, as he was a respected guest of high authorities. We know that there was “no hint of shortages before their departure from Egypt” [Plessas]

Most studies indicate the earliest detectable change occurs after 120 to 180 days [xx] although there are studies where early signs appear earlier [xxx]. But in this study, which was stopped after 3 months, no serious effects occurred.

3. “Clinical description is typical for scurvy”.

This is simply not true. The clinical description we have, from second hand accounts, are vague and non-specific. The clinical signs and symptoms of scurvy are well known and clearly described today [10]. The typical clinical signs for scurvy are absent from all accounts: gingival bleeding, an early and typical sign, or the “rotten mound” is never mentioned. Subcutaneous bleeding [11] – ecchymoses - or joint pains, leading to difficulties walking, are never mentioned. Gum bleeding are typical signs, and so are swollen and painful legs, also leading to difficulties in walking [12]. They are all absent from the accounts. Non-specific signs such as laziness are also typical, with muscle pain in the legs as an initial sign, but they always evolve into bleeding, gum problems, putrid smell and other signs that Vesalius would have described. As a doctor, Vesalius would have been well placed to recognize these signs and to describe them. None of them appear in any account.

Authors claiming typical signs were present make a lot of the so-called melancholy and refer to the writings of the 16th century expert Johannus Echthius who wrote a treatise about scurvy in Latin, as was customary in these days, in 1541, although it was only published after his death in 1556 [13] Despite being considered an expert on scurvy, Echtihius –and all “experts” of his day could recognize the disease – they knew little about the causes of scurvy, its link with vitamin C and the treatment. In fact Echthius and his 16th century colleagues were dead wrong about the causes of scurvy. Echthius obtained his knowledge entirely from studying Greek and Roman classics, Celsus, Galen and others, and came to the conclusion that scurvy was caused by a blocked spleen, leading to an excess of black bile. The treatment therefore consisted in hot and wet medicines like oil and vitriol. The only useful cure, citrus juice, was considered a “cold” medicine, therefore of no use [14]. Doctors at the time recommended avoiding fruits and vegetables in case of scurvy! Knowledge about the causes of scurvy would have to wait till the work of James Lind, an officer of the British Royal Navy who published his now famous treatise on scurvy in 1753 [15]

But Echthius did know how to recognize the symptoms of scurvy: stomachache, a complaint of the mouth, and sceletyrbe, a complaint of the legs. Vesalius showed none of these symptoms. 

In another argument in favour of the scurvy theory, it is claimed that extreme fear and irrational behaviour … are well known early symptoms [Plessas ]. This is not the case. Lind was correct when he observed that “a listlessness to action … a lazy inactive disposition” that degenerates in “a universal lassitude” [Hisrchman] are typical signs. This is also the observation of one of the authors (RC) having observed scurvy patients in Ethiopian prisons [xx]

Did Andreas Vesalius really die from scurvy on the island of Zakynthos in 1564?
Evidence does not support this theory.

NOTE:  The following article authored by Theo Dirix, and Dr. Rudi Coninx, is a rebuttal of Pavlos Plessas' theory that Andreas Vesalius indeed died from scurvy. The original article entitled "Powerful indications that Vesalius died from scurvy" by Pavlos Plessas was presented in a meeting at the island of Zakynthos in 2014.

There have been more items related to Vesalius’ life that were wrongly transmitted through time, but recent investigations have put to rest a number of “disputed” facts that were erroneously reported and commonly accepted. They often made into the general history books or even into Wikipedia. The two most glaring ones were

1. That Andreas Vesalius had to leave the Imperial Court in Spain because the Inquisition was investigating him for allegedly doing an autopsy on a person that was not yet dead.

Dr. Rudi Coninx, and Theo Dirix, authors of this article

2. That Andreas Vesalius was shipwrecked, and presumably drowned

• Vesalius did not die shipwrecked, as it was still alleged by Wikipedia recently [4] (but now corrected. His ship arrived safely at the harbour of the island of Venetian owned island of Zante (now Zakinthos, Greece) and Andreas Vesalius went ashore there.

What do we know for sure about the last days of Andreas Vesalius? 

• We know that Andreas Vesalius undertook a pilgrimage to Jerusalem in early March 1564, arriving in Venice late April, and that he sailed from Venice via Cyprus to Jerusalem in early May. He only stayed for a short time in Jerusalem, probably one month. He then traveled from Jerusalem through the Sinai desert to Alexandria, Egypt and boarded a Venetian ship there in September 1564, heading for Venice. 

• We know that the return journey was eventful. The ship was initially driven off course and then stuck without winds for over forty days which lead to food and water shortages on the ship. Most passengers fell ill, and many died. Their bodies were thrown overboard. This caused great anxiety to Andreas Vesalius who feared being thrown overboard unceremoniously in case he died. Vesalius became ill himself and lay sick in the hold with nobody taking care of him. (Account of Reinert Soleander, quoted by Biesbrouk et al.) [5].

• We also know that he stepped off the ship on the Venetian island of Zante (now Zakynthos in Greece) on October 15, 1564, sick, weak and frail, that he slowly walked towards the gates of the city where he collapsed and fell dead.

These are the facts that can be attested, and are not in dispute. What remains disputed is: did this 50 year old man die from scurvy, as is alleged?

In this article we will look at the arguments advanced in favour of the scurvy theory and see if there is any evidence to support these arguments.

Most arguments in favour of the scurvy theory have been proposed by Mr. Pavlos Plessas at the 2014 Vesalius Continuum meeting in Zakynthos, Greece and posted online on his blog (and here) [5]:

• “Vesalius stayed for six months in an area where Vitamin C was not easily found.
• Vesalius’s travels and sightseeing during the summer months means that some of his body’s Vitamin C reserves were lost through perspiration.
• Over the duration of his pilgrimage this could have exceeded 20% of his initial reserves. He then stayed an additional forty days at sea becoming vitamin C deficient.
• He reports Vesalius as immobile, depressed, with phobic and paranoid behavior,
• These can have sudden death syndrome upon restart of physical activity, which would also explain Vesalius' sudden death at the doors of the port of Zakynthos [7]..

One of the current challenges in medical sciences is to achieve a common and universal language that allows establishing, promoting the understanding and communication between people of different cultures and nationalities.

The use of anatomical and radiological terms in the chest is not exempt from this theme. An adequate terminology allows describing findings and unifying concepts that facilitate communication, teaching, research, in brief, the transmission of knowledge.

From the radiological point of view, ignorance of appropriate terminology creates confusion and may eventually lead to inaccuracies and misdiagnoses. Therefore, reaching consensus in terminology is an attempt to minimize the effects of language vices, which are unfortunately passed on to future generations.

On the other hand, in recent years, technical advances in radiology have improved the capture, recording and storage of images, which in turn has involved the need for a new language to explain new concepts.

Thus, as in 1971 a proposal for initial terminology was made, which was consolidated in 1984 and 1996 with the publications of the Fleischner Society glossary for Chest X-rays and Tomographies respectively. In 2008 (Radiology 2008; 246: 697-722) this glossary is finally updated using new terms, modifying or eliminating some of those that have become obsolete and others in which their meaning has changed.
