Recently, S-100 protein, one of the nervous-system-specific proteins, has been shown to be a useful marker for the epidermal Langerhans' cells. We investigated the localization of Langerhans' cells in human cholesteatoma specimens by means of an immunohistochemical method for detecting S-100 protein. A large number of Langerhans' cells containing S-100 protein immunoreactivity were found in the epithelium of the cholesteatoma and also in the subepithelial region. This immunoreactivity was detected both in the cytoplasm of the Langerhans' cells and their dendritic processes along their entire lengths. The number of S-100 positive Langerhans' cells in cholesteatoma associated with otorrhea increased significantly as compared with normal epithelium from the external auditory canal and tympanic membrane, while no increase in the number of S-100-positive cells was recognized in cholesteatoma without otorrhea. The S-100-positive dendritic cells in the cholesteatoma revealed longer and more complexly branched processes than those in normal tissues. These findings suggest that the Langerhans' cells within the cholesteatomatous lesion are responsible for generating and maintaining the chronic immunological reactions in this disease.","PeriodicalId":8300,"journal":{"name":"Archives of oto-rhino-laryngology","volume":"246 1","pages":"48-52"},"PeriodicalIF":0.0,"publicationDate":"1989-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/BF00454134","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13875374","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

After subjecting this bacterial strain to one animal passage, the bacteria were reisolated in nine of ten infected maxillary sinuses. All rabbits developed a unilateral purulent sinusitis, while a non-purulent sinusitis could be induced by occlusion only of the maxillary ostium. By using a non-diffusable tracer, microspheres labelled with Sn113, blood flow measurements were performed on these sinuses. These studies showed that the blood flow of the infected sinuses was significantly higher than on the control side. However, in chronic sinusitis (with a blocked ostium), the blood flow did not differ significantly from that on the control side. Biochemical studies in the animals with purulent sinusitis demonstrated that lactate concentration in the mucosa was significantly higher as compared to the control side. The glucose concentration was significantly lower in the mucosa of the infected side, as was the ATP content of the sinus mucosa in purulent sinusitis. These results indicate an increased glycolysis as well as a relative energy depletion in the sinus mucosa in purulent sinusitis, which could result in an impaired epithelial function.","PeriodicalId":8300,"journal":{"name":"Archives of oto-rhino-laryngology","volume":"246 5","pages":"315-7"},"PeriodicalIF":0.0,"publicationDate":"1989-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/BF00463583","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13732838","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Bearing this in mind, the most sensible solution appears to be the practice of a self-donor procedure with normovolemic hemodilution prior to elective surgery. However, even repeated bloodlettings do not modify the oxygen delivery to tissues since, with a reduction in the hemoglobin content of the circulating blood, there is a corresponding increase in oxygen availability. Since the reduction of circulating erythrocytes brings with it a reduction in blood viscosity, there is in turn an improvement in the microcirculation. The generally better tissue oxygenation, the reduction of the blood's viscosity and the increased circulatory perfusion all also favor a prophylaxis against deep vein thrombosis. We have currently performed 72 surgical procedures for head and neck neoplasms that were undertaken at the Clinical ENT Division of Treviso Hospital precisely with the normovolemic hemodilution described above. The self-donor transfusion technique was adopted with the help of the hospital's transfusion service. We have analyzed the data relative to this method and have found that the normovolemic hemodilution represents the treatment of choice in surgery-induced stress, particularly since this approach allows a better tissue oxygenation.","PeriodicalId":8300,"journal":{"name":"Archives of oto-rhino-laryngology","volume":"246 5","pages":"333-5"},"PeriodicalIF":0.0,"publicationDate":"1989-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/BF00463588","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13732841","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To enable these children to enjoy a relatively normal family environment despite a tracheotomy, it is desirable that they should be managed at home for at least part of the time. For the past 8 years we have routinely used soft polyvinyl chloride paediatric tracheotomy tubes (Shiley) in our patients. These tubes have proved to be relatively resistant to obstruction with secretions and are changed at 1- to 2-week intervals. They can be modified by making a series of three to four 2-mm through-and-through fenestrations around the shoulder in order to improve speech production and facilitate decannulation. Parents are tutored in tracheotomy care, which includes tube changing, humidification and suction. They are then permitted to take their child home from hospital when they are considered to be competent. Twenty-eight children (13 boys, 15 girls) with a mean age of 14.5 weeks (range 1-525 weeks) at the time of tracheotomy have been managed at home using this system. The median period of hospitalisation was 12 weeks (range 5-75 weeks), and the median duration of home management was 94 weeks (range 13-394 weeks). Sixteen patients have been successfully decannulated, 11 remain cannulated and 1 died at home from sudden infant death syndrome. Despite supportive measures, the majority of the children developed intermittent chest infections.(ABSTRACT TRUNCATED AT 250 WORDS)","PeriodicalId":8300,"journal":{"name":"Archives of oto-rhino-laryngology","volume":"246 5","pages":"345-8"},"PeriodicalIF":0.0,"publicationDate":"1989-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/BF00463591","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13733487","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The eye movements during these conditions were compared to the vestibulo-ocular reflex (VOR), to the cervico-ocular reaction (COR) and to the active COR (i.e., voluntary stabilization of the head in space while the trunk was moved sinusoidally). Each subject sat with eyes covered on a rotating chair. Sinusoidal movements having an amplitude of +/- 20 degrees and either 0.1 or 0.2 Hz were performed. Voluntary head movements and head movements with minimized cervical input showed no difference in the gain of the slow-phase velocity of the nystagmus, the saccadic activity (cumulated amplitude/time) and the maximum eye deviation. The distribution of saccades around the reversal of head movement in space represents the only significant difference between these conditions. While the saccades appear promptly after reversal during sinusoidal voluntary head movement, they appear during voluntary head movement with minimized cervical input just before the reversal of head movement in space. The direction of saccades always depends on the displacement of the head related to the trunk and is due to cervical input and/or central influences.","PeriodicalId":8300,"journal":{"name":"Archives of oto-rhino-laryngology","volume":"246 1","pages":"20-5"},"PeriodicalIF":0.0,"publicationDate":"1989-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/BF00454129","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"13875370","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
