JOURNAL FREE ACCESSIn the palatine tonsils with focal infection (26 cases of articular rheumatism, 16 cases of nephritis, 8 cases of febricula) were observed remarkable pathohistological changes as follows. The forms and ramifications of the tonsillar crypts were exceedingly complicated. The epithelial layers were incrassated or papillary, while others were thin, partly broken or forming ulcers. In some locations they were reticulated owing to the infiltration of many round cells. Iii the tonsillar crypts many desquamated horny epithelial cells and their detritus accumulated, and lymphocytes and neutrophil leukocytes often mixed, forming plugs. Complicated ramifications and windings of the tonsillar crypts interrupted the discharge of the plugs. There were many cystic dilations or cysts were formed in the peripheral parts. Besides these actinomycotic granulas and colonies of bacteria were also found in large quantities, and crypts were also found which showed signs of acute or subacute inflammation. Cyst formation was discovered at high percentage as one of the pathological changes caused by inflammation. In the lymphatic tissue were also observed granuloma with giant cells and scars caused by the destruction of the cysts. In the areas besides the crypts, remarkable mesenchymal reaction was observed. Trabeculae and capsules were incrassated and scarred, new blood vessels had grown, there was remarkable growth of the connective tissue of the tunica externa of the blood vessels, the parenchyma of the tonsil was atrophic. Most of the secondary nodules of the lymphatic tissue were in the active or reactive stage, but some were of the disturbance type. Various changes were observed in the blood vascular system. The changes were mostly incrassation and hyaline degeneration of tunica interna, hyperplasia of tunica externa, fibrinoid swelling of the connective tissue of the arterioles, remarkable infiltration of the plasma cells and lymphocytes around the venules. In a few cases analogous changes to Aschoff'sView full abstractDownload PDF (24632K) -

JOURNAL FREE ACCESSUm das Gerausch in der Gummifabrik und die damit verbundene Berufsschwerhörigkeit zu untersuchen, wurde erst die eingehende Bestimmung des Fabrikgerausches von uns angestellt. Die erhaltenen Resultate sind wie folgt:
1. In den sämtlichen Werkstätten der Gummifabrlk wurde die Stärke des Geräusches bestimmt und das Geräusch zeigte im Anklebungswerk 80-85 Phon, im Vulkanisierungswerk etwa 90 Phon, im Verfeinerungswerk 95-100 Phon und im Schnurwerk 95-110 Phon.
2. Aus der Frequenzanalyse ergab sich, dass das Geräusch der Gummifabrik im Vergleich mit demselben der anderartigen Fabriken in unvergleichlich vielen Werkstätten aus Hochfrequenztünen besteht. Im Schnurwerk beträgt das Geräusch 3000-6000 cps und in mehr als der Hälfte der Werkstätten, wie im Walzwerk, Schneidungs-. Anklebungs-, Vulkanisierungs-und Metallbearbeitungswerlc u. a. ist das Hochfrequenzgeräusch festzustellen, insbesondere im Schnurluftschlauchwerk ist das Geräusch sogar auf 6000 cps gesteigert.
3. Die Stärke dieser Gerausche und die Verteilung ihrer Frequenz wurden nach der zeitlichen Verschiebung beobachtet, aber wegen der Kompliziertheiten der Geräuschquelle konnte man auffallende zeitliche Schwankungen bemerken.
4. Auf Grund dieser Geräuschbestimmungen wurden die Erlaubnisgrenze schädlicher Geräusche, die Schalldämpfungsvornahme, die Verwendung von Schutzmitteln gegen das Geräusch und ferner die fur einen längeren Zeitraum anhaltende Gesundheitsverwaltung für das Hörvermögen einer eingehenden Kritik unterzogen. Über die Frage der Berufsschwerhörigkeit wird in der nachfolgenden Arbeit gesagt.View full abstractDownload PDF (2243K) -

JOURNAL FREE ACCESSKürzlich hat sich Tympanoplastik auch in Japan in die Praxis eingeführt, wozu ist natürlich durchaus notwend ig, die Verhältnisse des Schalleitungskettenmechanismus von Ossiculum auditus kennen zu lernen. In diesem Sinne ist die von Zöllner eingeleitete Hörprufung durch die Schallsonde von grosser Bedeutung.
Durch eine eingehende Kritik über die Eignung verschiedener Sonde zur vorliegenden Hör-prüfung haben wir neue Apparate konstruiert und sie in einigen klinischen Fällen durchgeprüft. Dies soll hier kurz mitgeteilt werden.
1) Aus vergleichenden Untersuchungen von Metall und Nylonsonde erwies sich die letztere deswegen als ungeeignet, weil sich dabei der reine Ton unter 500 cps stark verbiegt. Also ist die Anwendung von Metallsonde vorzuziehen.
2) Unter Metallsonden ist es die gerade Schallsonde, welche den Originalton am genauesten leiten kann. Der Ton, welcher durch die bogenförmig oder knieartig gekrümmte Sonde geleitet wird, wird verbiegt.
3) Verwenden wir zur Sondenaudiometrie die von uns Konstruierten, die Schallsonde befestigenden Einrichtungen und das den Kopf fixierende Kissen, so ist die Hörprufung relativ leicht und exakt vorzunehmen, ohne zugleich die Versuchsperson bei der Prüfungszeit irgendeinen Schmerz empfinden zu lassen.
4) Bei der Sondenaudiometrie an normalen Menschen sind die Schwellenwerte des Hör-vermögens nach der Lage des Trommelfells in der Reihenfolge von Manubrium mallei, Nabelteil, Processus brevis mallei und hinterer Wand des äusseren Gehörganges vermindert.View full abstractDownload PDF (5769K) -

JOURNAL FREE ACCESSThe authors report here an outline about 3 cases of chronic otitis media with remarkable ossification of the tympanal mucous membrane. They confirmed that these ossicles were histologically the bony tissues irregularly and newly born.
They presumed from their clinical experiences that these ossifications first developed thinly capsule-like behind or at the back side of the body and the short foot of the incus, gradually spread toward the anterior part of the epitympanum and to the aditus ad antrum and lastly became to envelop entirely the body of the incus and the head of the malleus.
They also guessed that in that case adequate stimulation of mild chronic inflammation lasting for a long time was an essential factor.View full abstractDownload PDF (4919K) -

JOURNAL FREE ACCESSOctamin tablets containing paraverine hydrochloride, nicotinic acid, tioctic amide and other vitamins are designed to improve blood circulation and metabolism of the inner ear.
The authors have shown that of these ingredients papaverine hydrochloride has a remarkable efficacy of increasing blood flow in the inner ear. They administered this drug to the patients of Ménière's disease and other inner ear diseases, and perceived a remarkable healing efficacy for tinnitus in the patients of Ménière's disease as well as for vertigo.
They concluded that this drug ought to be tried in the treatment of inner ear diseases.View full abstractDownload PDF (2857K) -

JOURNAL FREE ACCESSA 51-year-old female with multiple myeloma and a 79-year-old female with heart-failure accidentally swallowed their incomplete dentures with two hooks respectively. Esophagoscopically these foreign bodies were found in the thoracic esophagus, but the endoscopical removal of these dentures had to be discontinued, as one of two hooks (in the 1st case) or the sharp protrusion of the dental plate (in the 2 nd case) were so tightly impacted at the cricopharyngeal pinchcock that the operator could not withdraw the foreign bodies further. Other reasons why the authors gave up the endoscopical removal of these foreign bodies were the emaciation of the patients, a fear of pathological fractures during the endoscopy (in the 1st case) and the cardiac diseases of the 2nd patient.
The removal of the foreign bodies in each case was successfully carries out by external esophagoscopy. On these occasions the operator removed the foreign bodies through the incision wound of the esophagus, bringing the foreign bodies up to the cricopharyngeal pinchcock by oral esophagoscopy.
This method of removal of foreign body in the esophagus is characterized by
1) preventing the infection of the neck wound,
2) shortening the duration of operation and
3) simple removal of such kind of foreign body.View full abstractDownload PDF (5546K) -
