Upper lip reconstruction and aesthetic aspects in the female patient: our point of view
No full textBrief title: A brief description of our point of view about upper lip reconstruction supporting a quite simple and effective surgical option, which surgeons could consider whenever little neoformations must be removed from the lips, an aesthetically important anatomical region
The origins of the blood transfusion. European literature and italian debate on new innovations (1667-1668)
Full text linkThis paper deals with the literary debate on the first experiments regarding blood transfusion on human beings between 1667 and 1668 in Europe, with particular attention to the less-known experimental research, carried out in Italy. The authors examine the details of the experimental developments, focusing on the techniques and instruments used by physicians involved in this new surgical approach, with special attention to the Italian debate and experimentations. The article suggests that transfusion was considered a part of what we could call “emergency surgery”. In this framework, Italian transfusional pioneers played a central role in the improvement and transmission of a discipline that was still in its dawning throughout Europe. Moreover, the manuscript highlights the contribution of the “chirurgia infusoria” as an innovative therapeutic system for an immediate and rapid recovery. From this perspective, blood transfusion represents a surgical practice for reanimation and resuscitation. The objective of this work was to analyze the importance of foreign literature and the English and French disputes presented by Davia in Italy, which made them known. Despite foreign prohibition in Italy, experiments with animal-to-human transfusions continued after 1648. A papal bull excommunicating scientists for conducting such research has never been found
Reconstruction of posterior auricular ear surface defects: “Ear Keystone graft”
No full textMalignant cutaneous tumors are common on the external ear1 and reconstruction of posterior auricular surface's defects after surgical removal of cancer can be performed using different strategies. These techniques can be not easy or not really quick to perform, therefore we believe that it can be useful to propose another strategy to evaluate between the different reconstructive options in this anatomical region.
The Keystone Design Perforator Island Flap (KDPIF), a curvilinear shaped trapezoidal design flap described by Felix C Behan in 2003,2 is a solution to reconstruct soft tissue defects in head and neck, trunk, and extremities. Based on fasciocutaneous perforators, this flap offers both the robust vascularity of perforator flaps and the relative ease and speed of local tissue rearrangement.
In this regard we present our experience with the use of the KDPIF for the posterior surface of the auricle's reconstruction after removal of a skin epithelioma. This application of KDPIF has never been described in literature and it is a special feature due to the lack of perforating vessels that supply blood to the flap in this anatomical region
The medical historical cultural foundations of western nasal surgery from ancient greece to the middle ages
Full text linkThe manuscript aims to clarify the origins of Western rhinosurgery through the ancient texts of the greatest physicians of the past, up to the Byzantine Era, focusing on the "exchange of knowledge" between peoples. This excursus is carried out by quoting the texts of the greatest doctors of the past, such as Hippocrates, Galen and Celsus and by analysing the works of Byzantine authors such as Oribasius, Aetius, Antillus, which, more than others, represent the moment of fusion and interpenetration of Ancient Medical knowledge, paving the way for the Medieval Scholae Medicae in the West. The aim, therefore, is to fill that sort of "great gap" (from the foundation of Constantinople in the 4th century AD to the early Arab culture in the 11th century AD) due to the fact that figures such as Branca, Vianeo and, finally, Tagliacozzi, are considered direct actors of a recovery of the "ancient knowledge" of classic authors. This literature tends to less evaluate, instead, that important and huge cultural exchange -literally osmotic- in medical and surgical knowledge between peoples and civilizations, that find a trait d'union in the application of medical knowledge and surgical practical techniques matured in the Byzantine, Arab and Early Medieval period. In final analysis, through the History of Rhinosurgery, this paper aims to highlight how Western medical knowledge is made up of the ensemble of cultures which are apparently distant and different from each other, which merge themselves in a truly universal and transcultural knowledge: the Medical knowledge
Bifid median nerve and carpal tunnel syndrome. An uncommon anatomical variation
No full textDear sir, one of the most common entrapment neuropathy syndromes in clinical practice is "Entrapment of median nerve in carpal tunnel" also called "Carpal tunnel syndrome (CTS)" (Aydin et al., 2007; Huisstede et al., 2010). This syndrome is caused by entrapment of the median nerve in the wrist (Preston and Shapiro, 2005) when the pressure increases in the carpal tunnel. A high division of the median nerve proximal to the carpal tunnel, also known as a bifid median nerve, is a rare anatomic variation that may be associated with CTS and with persistent median vessels (Lanz, 1977). This anatomic variation has an incidence of 0,8% to 2,3% in patients with CTS. Lanz (1977) has characterized this anatomic condition of the median nerve in the carpal tunnel. These anatomic variants have been classified into four groups: - Group 0: extraligamentous thenar branch (standard anatomy); - Group 1: variations of the course of the thenar branch; - Group 2: accessory branches at the distal portion of the carpal tunnel; - Group 3: divided or duplicated median nerve inside the carpal tunnel; - Group 4: accessory branches proximal to the carpal tunnel. During dissection of the wrist performed for the treatment of a CTS under local anesthesia, we found an anatomical variation of the median nerve that was divided in two branches inside the carpal tunnel (Group 3 of Lanz Classification) and in which its radial branch passed through its own compartment. The two parts of the nerve seems to be unequal in size (Fig. 1). Moreover the nerve passed in carpal tunnel associated with a median artery, so we classified this variation in the group 3b of Lanz Classification (Fig. 2). The persistence of median artery coexisting with a bifid median nerve has been widely reported in surgical literature (Lanz, 1977; Barbe et al., 2005). Before surgical intervention clinical evaluation of patient and electrophysiological examination showed no differences compared to a non bifid median nerve entrapment syndrome. In conclusion the bifid median nerve may facilitate compression of median nerve in the carpal tunnel because of its increased cross sectional area even if it has no electrophysiological or clinical differential diagnosis in case of CTS. The aim of this letter is aware the physicians in order to borne in mind the possible presence of a median nerve variation during dissection of carpal tunnel in order to avoid the damage of this non common anatomical structures
