Case description: A patient with a Barrett oesophageal carcinoma and a resection of the oesophagus with gastric pull-up developed swallowing disorders 6 years and 2 months after the operation. Within 1 year and 7 months two recurrences of the tumor at the anastomosis were found and treated with combined chemoradiotherapy or chemotherapy respectively. 7 years and 9 months after the operation local tumor masses and destruction were present with no ability to orally drink or eat (full feeding by jejunal PEG tube): quality of life was poor, as saliva and mucus were very viscous (pulling filaments) and could not be swallowed and had to be spat out throughout the day and night resulting in short periods of sleep (awaking from the necessity to spit out). In total the situation was interpreted more as a problem related to a feeling of choking (with food or fluid) in the sense of a functional dysphagia rather than as a swallowing disorder from a structural stenosis.
At that time acetylcysteine (2 times 200 mg per day, given via the PEG tube) and irradiation with water-filtered infrared-A (wIRA), a special form of heat radiation, of the ventral part of the neck and the thorax were added to the therapy. Within 1 day with acetylcysteine saliva and mucus became less viscous. Within 2 days with wIRA (one day with 4 to 5 hours with irradiation with wIRA at home) salivation decreased markedly and quality of life clearly improved: For the first time the patient slept without interruption and without the need for sleep-inducing medication. After 5 days with wIRA the patient could eat his first soft dumpling although drinking of fluids was still not possible. After 2½ weeks with wIRA the patient could eat his first minced schnitzel (escalope).
Following the commencement of wIRA (with typically approximately 90–150 minutes irradiation with wIRA per day) the patient had 8 months with good quality of life with only small amounts of liquid saliva and mucus and without the necessity to spit out. During this period the patient was able to sleep during the night.
Discussion: The main physiological effects of water-filtered infrared-A (wIRA) are: wIRA increases tissue temperature, tissue oxygen partial pressure and tissue perfusion markedly.
The five main clinical effects of wIRA are: wIRA decreases pain, inflammation and exudation/hypersecretion, and promotes infection defense and regeneration, all in a cross-indication manner. Therefore there is a wide range of indications for wIRA.
The effects of wIRA are based on both its thermal effects (relying on transfer of heat energy) and thermic effects (temperature-dependent effects, occurring together with temperature changes) as well as on non-thermal and temperature-independent effects like direct effects on cells, cell structures or cell substances.
Conclusion: Besides in a variety of other indications for wIRA, in cases of swallowing disorders (functional dysphagia) and hypersalivation or hypersecretion of mucus the use of wIRA should be considered as part of the treatment regime for improving a patient’s quality of life.
Razina pročišćenosti alogenoga koštanog bloka = Variant purification of an allogeneic bone block
(2017)
Svrha: Ovaj kratak tekst izvještava o histološkoj analizi sastava komercijalno raspoloživih alogenih koštanih blokova Maxgraft®. Materijali i metode: Na temelju objavljenih histoloških metoda prazni uzorci alogenih koštanih blokova Maxgraft® dekalcificirani su, dehidrirani i uloženi u parafin prije histološkog i histokemijskog bojenja. Nakon toga na prerezima su se procjenjivala obilježja materijala, poput strukture koštanoga matriksa i druge komponente, uključujući kolagen ili stanice/stanične ostatke. Rezultati: Uočeno je da ovi koštani blokovi imaju trabekularnu strukturu s lamelarnom podorganizacijom. Dodatno su nađeni i stanični ostatci unutar lakuna osteocita i na vanjskim površinama trabekula zajedno s ostatcima intertrabekularnog masnog i vezivnog tkiva, te kolagene strukture, vezivno-tkivne stanice i stanični ostatci. Zaključak: U skladu s dosadašnjim istraživanjima, podatci iz ovoga teksta pokazuju da neke od certificiranih tehnika pročišćavanja ne omogućuju proizvodnju alogenog materijala bez organskih stanica i tkivnih komponenata.
Am Fachbereich Medizin und dem Klinikum der Johann Wolfgang-Goethe-Universität Frankfurt existierten bereits seit 2002 mehrere einzelne medizindidaktische Kurse. Diese Aktivitäten wurden 2011 strukturiert, ein umfassendes Kursangebot, das das breite Spektrum an Themen rund um die Lehre abdeckt, wurde aufgebaut und unter dem Dach der Frankfurter Arbeitsstelle für Medizindidaktik (FAM) am Fachbereich institutionalisiert. Folgende Faktoren waren für die erfolgreiche Umsetzung ausschlaggebend: vorhandene Programme in anderen Bundesländern (v.a. Baden-Württemberg, Nordrhein-Westfalen) mit entsprechenden Vorgaben, die Unterstützung der Studiendekane, die Verankerung der Teilnahme an medizindidaktischen Kursen in der Habilitationsordnung sowie eine kritische Masse von an der Lehre interessierten Mitarbeiterinnen und Mitarbeitern. Kernelemente des Angebots sind ein Basiskurs für alle neu eingestellten wissenschaftlichen Angestellten mit Lehrverpflichtung und ein modularer Aufbau des Programms, der individuellen Präferenzen bzw. Erfordernissen entgegen kommt. Gleichwohl die Teilnahme am Kursprogramm überwiegend verpflichtend erfolgt, zeigt sich eine hohe Zufriedenheit und ein nachhaltiger Wissenszuwachs bei den Kursteilnehmerinnen und Kursteilnehmern.
This project come out from our need to harness voices in Africa and Latin America, giving these voices an opportunity to converse, argue, synthesize, agree, and share ideas on the craft of writing, on life, on being and on thinking for the benefit of all. It was also an opportunity to create literary friendships and contacts between these two great regions. Generally, Latin America and Africa still have a lot of stories to share among themselves and with the rest of the world. There are still very strong untapped storytelling traditions in these continents. The stories in this volume are selected from an amazing range of entries to a call for contributions to an anthology on experimentation. It is hoped this robust selection will serve a wide variety of tastes in both Spanish and English, and that the book will open dialogue and the sharing of ideas between the two regions and the whole world. This is an invaluable contribution on many fronts.
