The First Description of Acute Compartment Syndrome, by Al-Zahrawi.

ABSTRACT: Acute compartment syndrome (ACS) is defined as increased pressure within a confined compartmental space, leading to a decline in the perfusion pressure of the tissue within that compartment. To date, the commonly held belief has been that ACS was first described by Richard von Volkmann in 1881. However, we propose that ACS was originally described by Abul Qasim Al-Zahrawi approximately 900 years earlier.

Poor outcome following percutaneous balloon mitral valvotomy in patients with atrial fibrillation.

Introduction: Atrial fibrillation (AF) is the most common arrhythmia in patients with mitral stenosis (MS) and it may increase complications and decreases success rates of percutaneous balloon mitral valvotomy (PBMV). This study aimed to investigate the short and long term results of PBMV in patients with AF compared to sinus rhythm (SR). Methods: In this cross sectional study, 1000 patients with MS who had undergone PBMV between 1999 and 2013 were enrolled including 585 and 415 patients with AF and SR respectively. Patients were followed for a mean of 7.27 ± 3.16 years. Clinical, echocardiographic and hemodynamic data were collected. Procedure success, in-hospital and long-term outcome were evaluated. Results: Patients with AF were older and had greater symptoms, mitral regurgitation, mitral echocardiographic score, and mitral pressure gradient before PBMV. PBMV success rate were significantly lower in AF group (P < 0.001). In-hospital complications, including severe mitral regurgitation, emergency mitral valve surgery, peripheral embolism and long-term complications, including mortality, re-valvotomy, mitral replacement surgery and peripheral embolism/stroke were significantly higher in patients with AF. Conclusion: AF leads to worse in-hospital and long-term outcome and lower PBMV success rate. Repeated assessment and early decision to PBMV in patients with MS to reduce AF and AF related complication seems necessary.

Emergence of whooping cough: notes from three early epidemics in Persia.

Whooping cough is a relatively new infectious disease afflicting human beings, compared with other infectious diseases, and is undergoing a resurgence despite decades of vaccination. The oldest known epidemic is thought to be the Paris outbreak of 1578. In this Historical Review, we describe three epidemics of whooping cough in Persia, which although arising roughly one century before the Paris outbreak, have not been examined in detail. A great amount of epidemiological detail was reported that not only distinguishes the various stages and complications of whooping cough, but also reveals unique immunological aspects of this disease. The first of these epidemics is the oldest recorded whooping cough epidemic. On the basis of epidemiological features, we propose that this whooping cough epidemic was the first to have taken place in Persia and might have been part of the first pandemic. This theory pushes back the date of first documented emergence of whooping cough by almost a century, which matches molecular data about its spread. Here, we discuss features of these early epidemics in relation to their initial emergence, potential origins, and spread to Europe.

Surgery for Gynecomastia in the Islamic Golden Age: Al-Tasrif of Al-Zahrawi (936-1013 AD).

The rise of European science during the Renaissance is greatly indebted to the flourishing of the sciences during the Islamic Golden Age. However, some believe that medieval Islamic physicians and in particular surgeons had been merely a medium for Greco-Roman ideas. Contrarily, in some medieval Islamic medical books, such as Al-Tasrif of Al-Zahrawi (936-1013), the surgical instructions represent a change in the usual techniques or are accompanied by a case history, implying that the procedure was actually undertaken. Along with the hundreds of chapters on different diseases and related medical and surgical treatments, Al-Tasrif includes a chapter on surgical techniques for gynecomastia. The present paper is a review of the description of the surgical management of gynecomastia by Al-Zahrawi as well as that of the ancient Greek, medieval, and modern medicine. Although Al-Zahrawi seemed to base his descriptions of surgery for gynecomastia upon those of Paulus of Aegina, his modification of the procedure and application of the medicinal substances might be indicative of Al-Zahrawi's own practice of the procedure. Al-Zahrawi's surgical procedures remained unchanged for many centuries thenceforward until the technological evolution in the recent centuries.
