    Pedanius Dioscorides was a Roman army surgeon in the first century A.D. His great work called De Materia Medica is widely accepted as the foremost pharmaceutical source of antiquity. Dioscorides was the originator of materia medica (pharmacology), and he took advantage of his extensive travels to study plants. Dioscorides was considered a major authority on simple drugs for sixteen centuries. De Materia Medica served as a corner stone for both western and eastern pharmaceutical and herbal writing, and was translated into Syriac, Arabic, and Persian, as well as Latin. The particular characteristic of medical therapy in the Medieval Period was the extensive employment of drugs of all kinds. For this reason, Dioscorides’ De Materia Medicawas not only studied closely, but it also became a text book that Turk-Islamic scientists frequently referred to in their writings.Pedanius Dioscórides fue médico cirujano en el ejército romano en el siglo I d.C. Su gran obra llamada De Materia Medica es conocida como la principal fuente de farmacopea de la antigüedad. Dioscórides fue el inventor de la materia medica, y aprovechó sus extensos viajes para dedicarse al estudio de las plantas. Dioscórides fue considerado una eminencia en el tema de las drogas de origen natural a lo largo de dieciséis siglos. De Materia Medica sirvió como piedra angular para los textos farmacéuticos y herbarios tanto en occidente como en oriente y fue traducida al siríaco, árabe y persa, además de al latín. La particular característica de la terapia médica en la época medieval fue el uso extensivo de todo tipo de drogas. Por esta razón, además de estudiarse minuciosamente, De Materia Medica de Dioscórides se convirtió también en un libro de texto al que frecuentemente hacían referencia los científicos turco-islámicos en sus escrituras

    Since the 1950s, oxidised regenerate cellulose (TABOTAMP ®) has been successfully applied for local haemostasis in intra- or postoperative bleeding complications. The scope of this medical product is large and it has found its place in oral and maxillofacial surgery. Although the application of TABOTAMP ® in medicine and dentistry is common, further complications next to the absence of the haemostatic effect may be encountered if used incorrectly. The aim of this article is an update on the proper use of TABOTAMP ®. Further, tips are provided for the indication-specific application of this useful agent in clinical practice

    Solcoseryl® is a protein-free haemodialysate, containing a broad spectrum of low molecular components of cellular mass and blood serum obtained from veal calves. Solcoseryl® improves the transport of oxygen and glucose to cells that are under hypoxic conditions. It increases the synthesis of intracellular ATP and contributes to an increase in the level of aerobic glycolysis and oxidative phosphorylation. It activates the reparative and regenerative processes in tissues by stimulating fibroblast proliferation and repair of the collagen vascular wall. The formulations of Solcoseryl® are infusion, injection, gel and ointment, and it is also available as a dental paste for inflammatory processes of the mouth cavity, gums and lips

    Is radical surgery of an inverted papilloma of the maxillary sinus obsolete? a case report

    Full text link
    Abstract Background Sinonasal inverted papilloma is a locally aggressive tumor arising from the Schneiderian membrane which lines the nasal cavity and paranasal sinuses. Aggressive surgical approaches, such as lateral rhinotomy, were used until recently for complete removal of the inverted papilloma. Currently, endoscopic resection is the gold standard in the treatment of inverted papilloma. However, there are situations that justify an open approach. For example there are studies that report a higher postoperative recurrence rate after endonasal endoscopic resection, particularly in the treatment of recurrent diseases. While endoscopic resection performed by an experienced surgeon is definitely a minimally invasive therapy, an open approach is not necessarily associated with functional and aesthetic disadvantages. This case report describes the treatment of inverted papilloma by an open approach. This has been described before but the new gold standard of endoscopic resection has to be taken into account before any treatment decision is made nowadays. Case presentation Contrast-enhanced magnetic resonance imaging of the head and neck area was indicated in a 72-year-old white German man who presented with suspected squamous cell carcinoma of his lower lip. Magnetic resonance imaging additionally revealed a 3×2 cm2 polycyclic arranged mucosal thickening with cystic and solid contrast affine shares at the antral laterocaudal area of his right maxillary sinus, extending from his right lateral nasal wall to his maxillary sinus floor. He received antral polypectomy with medial maxillectomy via a unilateral LeFort I osteotomy approach. His pterygoid plate was preserved. A histological examination demonstrated a tumor composed of hyperplastic squamous epithelium protruding into the stroma (surface epithelial cells grew downward into the underlying supportive tissue), thus producing a grossly convoluted cerebriform appearance. Two weeks later, the patient regained a well-formed maxilla without any restrictions. He has remained disease-free for 25 months following the surgery and surveillance was continued in our tumor clinic. Conclusions Endoscopic resection of an inverted papilloma continues to be the gold standard. However, some cases require a radical approach. This does not necessarily increase patient morbidity

    The Reconstruction of Nasal Septal Perforation with High Density Porous Polyethylene Covered with Fascia Lata: An Experimental Study on Rabbit Model

    ObjectivesEvaluation of a new material, high-density porous polyethylene (HDPP), which is covered with fascia lata, for experimental nasal septal perforation closure.MethodsTwenty New Zealand albino rabbits were included and divided into study and control groups. A lateral incision was made from the lateral aspect of the left nares to the incisura nasomaxillaris. After exposure of the cavum nasi, the nasal mucoperichondrium was elevated bilaterally. A full-thickness 0.5×0.5-cm perforation was created over the septum nasi with a No. 11 surgical blade. A fascia lata graft was used for the study group. The HDPP was covered with fascia lata and placed under the elevated mucosa. HDPP without a fascial covering was used in the control group. Four months after the procedure, magnetic resonance imaging was performed to evaluate resorption of the material. The animals were sacrificed, and the nasal septum was completely removed. Macroscopic and histopathological examinations were performed on the nasal septum.ResultsAll rabbits had survived after the 4-month period. Macroscopically, nine of 10 (90%) perforations were closed in the fascia lata-covered HDPP group. Histopathological examination of these nine rabbits revealed that the continuity of cartilage was disturbed in the perforation areas. Granulation tissue was inverted in areas in which the cartilage continuity was disturbed. The HDPP had remained intact at the edge of the perforation. In the HDPP group, six of 10 implants were still perforated (60%) and four (40%) were closed. The fascia lata-covered HDPP implant had a significantly higher perforation closure rate than that of the HDPP implant alone (P<0.05).ConclusionIn cases of septal perforation, it is better to cover the HDPP implant with fascia lata. This covered implant can be used for the repair of nasal septal perforations. HDPP implants are easy to work with and avoid the increased operative time and morbidity associated with harvesting autografts

    <p>Abstract</p> <p>Introduction</p> <p>Malignant melanoma is reported to metastasize to all organs of the human body. Although it is common for it to metastasize to the gastrointestinal tract, a melanoma located primarily in the gastric mucosa is an uncommon tumor. Gastrointestinal metastases are rarely diagnosed before death with radiological and endoscopic techniques.</p> <p>Case presentation</p> <p>In this case report the clinical course and treatment of a woman with melanoma of the stomach, without any other detectable primary lesion, is presented and discussed. A 55-year-old Turkish woman presented to our clinic with complaints of muscle pain and bone pain in the left side of her chest. During an upper gastrointestinal system endoscopy, dark cherry-colored, light elevated, round-shaped lesions were taken from her gastric fundus and from the first part of her duodenum. Biopsies from these samples were determined to be malignant melanoma by the pathologist.</p> <p>Conclusion</p> <p>Metastatic malignant melanoma cases should be examined through endoscopy for gastrointestinal metastases.</p
