Hippocratic concepts of acute and urgent respiratory diseases still relevant to contemporary medical thinking and practice: a scoping review.

BACKGROUND: The collected works of Hippocrates were searched for concepts on the diagnosis, prognosis, and treatment of acute and urgent respiratory diseases, with the objective to trace their origins in the Hippocratic Collection. METHODS: A scoping review was performed to map out key concepts of acute and severe respiratory diseases in the entire Hippocratic Collection. The digital library Thesaurus Lingua Graeca (TLG) was researched for references in the entire Hippocratic Collection regarding the epidemiology, pathophysiology, prognosis, diagnosis and treatment of acute respiratory diseases; then, the relevant texts were studied in their English translation by the Loeb Classical Library. RESULTS: Hippocratic physicians followed principles of treatment for pneumonia and pleurisy, still relevant, such as hydration, expectoration, analgesia and prompt mobilisation. Other approaches, including the inhalation of "vapours through tubes" in angina, can be considered as forerunners of modern medical practice. Thoracic empyema was diagnosed by shaking the patient and direct chest auscultation after "applying your ear to his sides". In case of an emergency from upper airway obstruction, urgent insertion of primitive airway equipment, such as a small pharyngeal tube, was applied. CONCLUSIONS: The main Hippocratic concepts on four still common acute and urgent respiratory diseases -pneumonia, pleurisy, thoracic empyema and upper airway obstruction- were identified and most of them were found to be in agreement with contemporary medical thinking and practice.

Tracheotomy: historical review.

The authors review the ancient history of tracheotomy and bring the subject up to date (2008) by including the modern history of this procedure. In the past 60 years, there have been many advances in the knowledge of respiratory function that have been utilized to expand applications of the tracheotomy procedure. Improvements in the care of tracheotomized patients and the application of modifications in the available variety of tubes and ancillary equipment and procedures have made this a much more effective and widely utilized way of caring for the pulmonary cripple as well as utilizing it in the classical fixed obstruction of the upper airway.

[The history of thymus surgery]. / Die Geschichte der Thymuschirurgie.

Thymus surgery was initially dominated by the erroneous interpretation of the organs' pathogenicity and associated thymus diseases. Misleadingly, the thymus gland was made responsible for dyspnoea in children and a transcervical ektropexia was performed in a child suffering from dyspnoea in 1896. After F. Sauerbruch's thymectomy in a patient with myasthenia gravis syndrome (MG), A. Blalock established thymectomy in the 1940s for the treatment of MG. At the same time, the drug treatment initiated by M.B. Walker increased in significance. Despite progress in surgical techniques and the molecular understanding of MG pathogenesis, randomized controlled trials, which would increase the evidence for surgical access and indications for surgery compared to immunosuppressive treatment in MG, are lacking.

Rings, slings, and other things: vascular compression of the infant trachea updated from the midcentury to the millennium--the legacy of Robert E. Gross, MD, and Edward B. D. Neuhauser, MD.

In the first half of the 20th century, pediatric chest imaging was limited mainly to the performance of conventional radiography, including barium esophagography and occasionally bronchography and angiography. Despite this limited imaging approach, by 1950 the diagnosis and treatment of vascular "rings" compressing infant airways had been accomplished with the pioneering efforts of Robert E. Gross, MD, in the field of surgery, and Edward B. D. Neuhauser, MD, in the field of radiology. The next two decades brought the recognition of pulmonary arterial "sling," or anomalous left pulmonary artery, in diagnosis and treatment. Recognition of still another vascular compressive syndrome in infants was identified as that due to the absence of the pulmonary valve. These "rings, slings, and other things" are now evaluated with magnetic resonance (MR) imaging, including MR angiography, and computed tomography (CT), including CT angiography, with the added use of three-dimensional reconstruction. These are the legacies of Drs Gross and Neuhauser.

Oropharyngeal and nasopharyngeal airways: I (1880-1995).

PURPOSE: During the past decade the laryngeal mask airway (LMA) has dominated literature about airways for use during general anaesthesia. The LMA addresses clearly defined clinical objectives. The purpose of this study is to determine whether those objectives were described collectively with reference to earlier airway designs. METHODS: The anaesthesia sections of Index Medicus 1880-1995 were read and publications in the English language about airways were obtained and analysed. Secondary information sources were references to causes of respiratory obstruction. This was supplemented by random reference to available textbooks. RESULTS: The multiple objectives, as least partially, satisfied by the LMA were not described collectively at the time of Hewitt's presentation of an oropharyngeal airway in 1908 and largely were neglected until the present time. CONCLUSION: The design of airways has been based on clinical circumstances and perceived requirements of the time. In contemporary anaesthetic practice, distinct clinical situations still occur and there is a role for different device designs. Currently for supraglottic airway management during general anaesthesia, four types of airway should be available: a Guedel airway, nasopharyngeal airway, a laryngeal mask airway, and an airway specifically designed to facilitate blind tracheal intubation.
