Did Ibn Zuhr (Avenzoar) Postulate Before Vesalius That Liquid Collects in Ventricles in the Hydrocephalus?

OBJECTIVE: This study aimed to present and evaluate the part of Avenzoar's Liber Teisir that pertains to hydrocephalus. Avenzoar was an Andalusian physician prominent in the history of medicine because of the broadness of his observations and original methods. His most important work is recognized to be the Al-Taysir fi al-Mudawat wa al-Tadbir (On Preventive Regimen and Treatment), and its Latin version, Alteisir scilicet regiminis et medelae, which was in use for centuries in Europe. METHODS: The Arabic (Rabat, Morocco, in 1991) and Latin (Venice, Italy, in 1530) versions of Avenzoar's work were perused, relevant sections were separately translated into English, and both translations were then compared. An English version was prepared and is given in our results. RESULTS: The location of liquid collection was described as the anterior ventricles of the brain and around the brain. CONCLUSIONS: Avenzoar might have noted one of the earliest records on the clinical state called idiopathic adult hydrocephalus and postulated liquid collection in the ventricles of the brain in hydrocephalus before Vesalius.

One of the Earliest Accounts of Head Wounds in Firdaws al-Hikma by al-Tabari from the 9th Century.

OBJECTIVE: To present the first Arabic text on suturing scalp wounds. METHODS: A related section entitled "On the wounds in the head" from the book Firdaws al-Hikma (Paradise of the Wisdom) written by al-Tabari in the 9th century was identified and analyzed. This work was one of the earliest medical compendiums in the Islamic world during the medieval period. A printed copy of Firdaws al-Hikma edited by Muhammad Zubayr al-Siddiqi was examined, and findings were compared with relevant knowledge in the literature. RESULTS: A notable part of this text is based on appropriate closure of scalp wounds using sutures. Before this work, only the well-known Indian medical book Susruta-Samhita had mentioned closure of scalp wounds using sutures. In his work, al-Tabari recommended using materials made of silk or linen for suturing. He additionally proposed some recipes that have a coating feature that prevents bleeding from the wound after it was closed properly. He also dealt with persistent swelling and provided formulas for solving the problem with special compositions. CONCLUSIONS: Firdaws al-Hikma is a noteworthy work in the history of medicine, and it includes a unique chapter on head wounds. To the best of our knowledge, this is the first mention of suturing scalp cuts in Arabic literature and the second reference in medical literature after the Indian work Susruta-Samhita.

Account of Haly Abbas regarding the management of hydrocephalus in children: a text from medieval times.

OBJECTIVE: To present the text on hydrocephalus from Haly Abbas's book Kitab al-Maliki / Liber Regius (The Royal Book), which was accepted as a classical textbook in the Eastern and Western worlds for a long time. METHODS: The Arabic (Süleymaniye Manuscript Library, Murad Molla Collection, Nr: 1482 and Bulak, 1294 /1877) and the Latin (Venice, 1492) versions of the related chapter was translated and compared to create an English text. Additionally, relevant literature was reviewed in detail. RESULTS: The text on hydrocephalus in Haly Abbas's The Royal Book virtually resembles Paul of Aegina's work. For hydrocephalic cases where the fluid collects between skin and pericranium, and pericranium and bone, Haly Abbas had made little change in surgical intervention; for the third type, skin incision, he preferred a T-type incision instead of an H-type. Like Paul of Aegina, Haly Abbas also did not advise any surgical intervention for the cases of hydrocephalus, where fluid accumulation is between bone and the dura mater. CONCLUSIONS: Haly Abbas's approach to hydrocephalus was as brave as that of his predecessors Antyllus, Oribasius, and Paulus, although the cases they dealt with were almost all cephalic hematomas. Although his chapter on the treatment of water accumulation in the head contains surgical interventions in extracranial hydrocephalic conditions, his account on hydrocephalus is extremely precise and gives adequate detail as in other chapters in his book.
