Galen's place in Avicenna's The Canon of Medicine: Respect, confirmation and criticism

The Role of Ancient Greek Physicians in the Development of Tracheostomy: Pioneering Airway Interventions and Early Thoracic Surgery

Tracheostomy, a critical airway intervention, has a long and complex history that dates back to antiquity. While the earliest references to the procedure appear in Egyptian and Indian medical texts, its development within ancient Greek medicine remains a subject of historical debate. This study explores the evolution of tracheostomy in ancient Greece, analyzing its theoretical foundations, historical accounts, and surgical advancements. Despite Hippocratic opposition, which largely discouraged invasive airway procedures due to the risk of fatal complications, later physicians such as Asclepiades, Aretaeus, and Antyllus made significant contributions to refining airway management techniques. The anatomical studies of Galen further advanced the understanding of respiratory physiology, including early concepts of artificial ventilation. Additionally, this study examines archaeological evidence, such as a marble relief discovered in Abdera, which may depict an early attempt at tracheostomy, providing valuable insight into the practical application of airway interventions in antiquity. By comparing ancient Greek surgical techniques with modern tracheostomy practices, this research highlights the continuity of medical knowledge and innovation. It underlines the role of ancient Greek physicians in shaping the principles of thoracic surgery, offering a broader understanding of how early medical practices have influenced contemporary airway management. The findings contribute to the historical perspective on tracheostomy, emphasizing the timeless pursuit of life-saving surgical advancements and the evolving relationship between theoretical medical knowledge and practical surgical application.

Effect of Dill (Anethum graveolens) Oil on Pruritus and Quality of Life of Hemodialysis Patients: A Randomized Double-Blind Three-Arm Controlled Trial

Introduction

Anethum graveolens (AG), commonly known as dill, is a plant from the Apiaceae family that has been traditionally used as a skin softener and purifying agent in Persian medicine. In a previous study conducted on male rats, dill was found to have anti-inflammatory effects. The current study aimed to examine the efficacy of topical application of Anethum graveolens oil on pruritus severity, skin dryness, sleep quality, and quality of life in patients undergoing hemodialysis.

Methods

In the current clinical trial, the participants were randomly assigned to one of these groups: topical AG preparation, sesame oil, or a control group receiving no treatment. The study was double-blind and placebo-controlled. The topical treatment was applied twice a day for one month to areas of the skin affected by pruritus. The outcome measures included the severity of skin dryness, the Pittsburgh Sleep Quality Index, Duo's Uremic Pruritus Severity Scale, and the Itchy QoL questionnaire.

Results

This study involved 106 hemodialysis patients, and after intervention for one month, the medication group had a significantly lower mean score of sleep quality (3.24 ± 2.41) than the placebo (4.54 ± 3.11) and control (5.05 ± 3.21) groups (P=0.032). The mean change in pruritus severity was significantly greater in the medication group (-17.28 ± 8.938) than the placebo (-5.91 ± 5.398) and control (-3.43 ± 3.228) groups (P < 0.001). Moreover, a significant difference was observed in the mean changes in quality of life between the medication, placebo, and control groups, with values of -14.88 ± 7.89, -5.34 ± 4.50, and -1.92 ± 2.86, respectively (P < 0.001). Furthermore, both the medication and placebo groups showed improvement in skin dryness compared to the control group having the values of -1.65 ± 0.91, -1.11 ± 0.79, and -0.38 ± 0.54, respectively (P < 0.001).

Conclusion

Topical Anethum graveolens preparation significantly improved the sleep quality and quality of life and reduced skin pruritus and dryness in hemodialysis patients. It could be considered as a simple therapeutic modality to control pruritus in hemodialysis patients. This trial is registered with IRCT2017022032671N1.

The Effect of Metabolic Persian Diet on Ovulation Induction in Infertile Women

Introduction

Infertility is an important issue with a high social and psychological burden. From the perspective of Persian Medicine (PM), uterine cold temperament is one of the important causes of female infertility.

Aim

The aim of this study was to study the effect of PM or Iranian traditional medicine on improving ovulation and fertility.

Methods

From January 2017 to August 2017, sixty infertile women with eugonadotropic ovulation disorder were randomly divided into two groups. Both groups were treated with clomiphene citrate, except that the intervention group also received metabolic Persian diet (MPD). In each cycle, the dominant follicles and endometrium were investigated with ultrasound. At the end of the cycle, beta human chorionic gonadotropin (β-HCG) was evaluated and if positive, another ultrasound was performed two weeks later to confirm early pregnancy.

Results

The number of dominant follicles from the first to third cycle increased from 2.15 ± 1.14 to 2.28 ± 0.61 in the intervention group and decreased from 1.86 ± 0.79 to 1.30 ± 0.47 in the control group. The dominant follicle size changed from 16.00 ± 4.08 to 18.78 ± 2.78 and from 15.05 ± 3.11 to 15.80 ± 3.89 in the intervention and control groups, respectively. But endometrial thickness did not change significantly in the intervention group. Pregnancy results based on β-HCG and ultrasound findings were positive in 19 and 16 patients in the intervention group and in 10 and 7 patients in the control group, implying significantly higher numbers in the first group.

Conclusion

It seems that MPD may be effective in the success of ovulation induction.

"Islamic Medicine": A true discipline for the 21st century or quackery?

The purpose of this review is to consider the position of "Islamic Medicine" and whether it is a legitimate form of clinical care or quackery. The analysis is based on published work together with an identification of themes derived from testimonials on practitioners' websites, as well as a consideration of how such therapies are considered in medical search engines. "Islamic Medicine" covers Traditional or Yunani practice, Prophetic Medicine, Hijama and Ruqya. Their origins are discussed and, subsequently, current-day practice and its relationship to allopathic medicine. Reasons for antagonism to modern medicine are considered and the absence of a rational basis for many of the views expressed. In the case of Yunani medicine, its pre-Islamic origins are identified together with the impact of anti-colonialism and the potential role of clerics in wishing to distance medical care from Galenic concepts. In the case of Hijama, the absence of effective training and regulation and its promotion as a "lost sunna" are discussed alongside claims for miraculous cures. The movement of Ruqyah away from Qur'anic recitation in support of the sick towards a popularised approach to dealing with magic and possession is considered, together with consequential adverse publicity in the media. The consequences of a failure to adopt training practices for Yunani medicine, as recommended by the WHO, are identified. Accredited detailed courses monitored by external statutory regulatory agencies, based in institutions committed to providing the best healthcare, and supporting research would allow "Islamic Medicine" to become a significant role player in contemporary clinical practice and stop present-day quackery.

Cardiovascular and pulmonary interactions: why Galen's misconceptions proved clinically useful for 1,300 years

The new generations of physicians are, to a large extent, unaware of the complex philosophical and biological concepts that created the bases of modern medicine. Building on the Hellenistic tradition of the four humors and their qualities, Galen (AD 129 to c. 216) provided a persuasive scheme of the structure and function of the cardiorespiratory system, which lasted, without serious contest, for 1,300 yr. Galen combined teleological concepts with careful clinical observation to defend a coherent and integrated system in which the fire-heart-flaming at the center of the body-interacts with lungs' air-pneuma to create life. Remarkably, however, he achieved these goals, despite failing to grasp the concept of systemic and pulmonary blood circulations, understand the source and destiny of venous and arterial blood, recognize the lung as the organ responsible for gas exchange, comprehend the actual events taking place in the left ventricle, and identify the source of internal heat. In this article, we outline the alternative theories Galen put forward to explain these complex phenomena. We then discuss how the final consequences of Galen's flawed anatomical and physiological conceptions do not differ substantially from those obtained if one applies modern concepts. Recognition of this state of affairs may explain why the ancient practitioner could achieve relative success, without harming the patient, to understand and treat a multitude of symptoms and illnesses.
