We compared different nail types in the bone-implant complex (BIC) of four unreamed solid nails and a slotted, reamed nail to see if there are major differences in stiffness for axial load, bending and torsion. We simulated comminuted mid-shaft fractures by a 2 cm defect osteotomy in paired human cadaver femora. Each bone was tested intact in a Universal testing machine. The results were recorded, osteotomy and osteosynthesis were performed, and the BIC was tested. Relative stiffness was calculated for each individual bone. For P-values less than 0.01 ('least significance difference test') the difference between groups was considered to be significant. In torque testing the unslotted solid nails showed significantly more stiffness (0.6-1.8 Nm/degree) compared to the slotted nail (0.2 Nm/degree). Compared to intact bone (6.9 Nm/degree), both groups of nails were significantly less stiff (relative stiffness 2-20%). In axial load and bending testing, the large-diameter unreamed nail showed greater higher stiffness (32-68%). This study shows that stiffness of the BIC in interlocking femoral nails is more dependent on nail profile than on the press-fit of nails in the medullary canal. For torque stiffness the absence of a slot is of special importance. According to our study, all of the unslotted nails tested give adequate stability for fracture fixation.","PeriodicalId":17985,"journal":{"name":"Langenbecks Archiv fur Chirurgie","volume":"382 3","pages":"167-72"},"PeriodicalIF":0.0,"publicationDate":"1997-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20258615","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}

Therefore, preoperative localization of the tumor is essential.Methods: From April 1986 through April 1997, 137 patients with MTC were operated on at our clinic. In 22 patients with recurrent tumor which had not been radiologically localized, 28 selective venous catheterizations (SVC) with determination of calcitonin levels were carried out.Results: In 23 examinations a suspected tumor could be identified (nine cervical unilateral, seven mediastinal, four cervical unilateral and mediastinal, one cervical bilateral and mediastinal, one liver, one cervical unilateral and liver). In 18 cases surgery was performed for recurrence (nine cervical revisions, one mediastinal dissection, six cervicomediastinal dissections, two laparotomies). In 15 of 18 cases, tumor tissue was found in the previously suspected area. In ten cases serum calcitonin levels dropped postoperatively by 6%-75%. A normalization of the hormone level was achieved only once by yet another operation. During further follow-up, five of the reoperated patients died from their disease. The other 17 patients are being followed up, whereby calcitonin levels are elevated but there is no clinical or radiological evidence of tumor.Conclusions: Although in the patient cohort presented a normalization of serum calcitonin could be achieved only once, the authors consider SVC useful because it is the only means of localization of tumor tissue in cases of negative radiologic studies and therefore allows a planned approach to the operation procedure in these cases.","PeriodicalId":17985,"journal":{"name":"Langenbecks Archiv fur Chirurgie","volume":"382 6","pages":"295-301"},"PeriodicalIF":0.0,"publicationDate":"1997-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20421120","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 risk of severe mycosis increases after a major operation and when a patient is taking broad-spectrum antibiotics, is on total parenteral nutrition, is catheterized, and/or is immune-suppressed. In the past years the incidence of nosocomial fungal infections (usually Candida spp.) has risen significantly. Five percent of CAPD-related peritonitis is caused by fungi. In enteral anastomosis breakdown, invasive mycosis occurs more often, with an accompanying lethality of up to 80%. In severe pancreatitis, up to 5% of peripancreatic necrosis is infected with fungi. The clinical course of severe mycosis, like the septic syndrome, is associated with fungemia in up to 50% of cases. As most of the facultative pathogenic fungi are part of the physiological flora, it is difficult to interpret mycological cultures. In order to diagnose invasive fungal infections, histopathological techniques and serologic tests for antigens and antibodies are available. Three antifungal agents (amphotericin B, flucytosine, fluconazole) are available for intravenous administration. Amphotericin B is given at doses of up to 1 mg/kg per day, in liposomal galenism up to 3 mg/kg per day. Combining amphotericin B with flucytosine (150-200 mg/kg per day) a synergistic effect is reached. Fluconazole at a dosage of 200-800 mg per day represents an alternative with similar antifungal activity and lower side effects.","PeriodicalId":17985,"journal":{"name":"Langenbecks Archiv fur Chirurgie","volume":"382 4 Suppl 1","pages":"S5-8"},"PeriodicalIF":0.0,"publicationDate":"1997-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1007/pl00014644","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20267640","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}

Males showed a significant increase of mast cell densities after electrical stimulation (1.0 mA, 5 Hz, 5 ms, 12 min) in the lamina propria. Simultaneously, we observed a significant increase of tissue histamine levels (ANOVA: P < 0.05), whereas serum levels remained unchanged. However, even though females had significantly higher levels throughout compared to males (ANOVA: P < 0.05), they did not show any significant reaction to electrical stimulation. These in vivo data support morphological and in vitro data from other investigators, who hypothesized a functional interaction between mucosal mast cells and nerves. However, degranulation seems to be a poor in situ indicator for mast-cell stimulation, as mast-cell densities increased in males, while the percentage of degranulated cells remained the same in all groups (about 40%). Instead, electrical stimulation of the vagal nerve seems to trigger histamine synthesis, or simply stabilization of mast cells. Interestingly, this phenomenon seems to be sex-dependent, suggesting a regulatory role for sex hormones in this scenario.","PeriodicalId":17985,"journal":{"name":"Langenbecks Archiv fur Chirurgie","volume":"382 3","pages":"157-63"},"PeriodicalIF":0.0,"publicationDate":"1997-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"20258612","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}
