Breast cancer is one of the most commonly seen malignant tumors in the female population, and it ranks the first in the incidence of malignancies among women. The skeleton is a common metastatic site for advanced breast cancer and is where spinal metastasis is most frequently seen. The incidence rate of spinal metastasis in descending order is as follows: thoracic vertebrae, lumbar vertebrae, sacrococcy-geal vertebrae and cervical vertebrae. Although osseous metastasis of breast cancer is very common, cases with metastasis to all vertebral bodies is currently very rare. The diagnostic method of osseous metastasis of breast cancer typically includes radiograph, CT and MRI. Ordinary radiograph has a high specificity but a low sensitivity, so total vertebral body metastases can only be detected when the extent of osteoclasia exceeds 50%. Some diagnostic shortcomings remain, although the sensitivity of CT and MRI has been greatly improved compared to the radiograph. At present, the most advanced synchronous PET-CT visualization can presumably raise the sensitivity and specificity in the diagnosis of breast cancer, based on the features of 18F-FDG imaging, and combined with morphologic change and precise localization. The following case report is in regard to a patient with total vertebral body metastasis from breast cancer detected by PET-CT.  相似文献

Objective: The aim of our study was to evaluate the efficacy of 89Sr combined with Technetium [^99Tc] Methylene- diphosphonate Injection (^99Tc-MDP) in the treatment of cancer pain in the advanced breast cancers with bone metastases. Methods: A total of 80 patients with various degrees of bone pain due to multiple metastases of breast cancer were treated with ^89Sr combined with ^99Tc-MDP. ^89Sr was given intravenously at 4mCi on day 1 during the 3-month schedule. After 7 days, ^99Tc-MDP was given at 22 rag/day on days 1-10 during the 1-month schedule, for 3 to 6 months. Results: The effective rate of relieving pain was 83.75%. The effective rate of curing bone metastases was 81.25%. So there was a significant improvement in the quality of life of the patients. Conclusion: ^89Sr combined with ^99Tc-MDP are effective in the treatment of cancer pain in the breast cancers with bone metastasis, and can obviously repair the bone destruction caused by metastases, thereby improving the quality of life in advanced breast cancer patients with bone metastases.  相似文献

AIM: To evaluate prognoses after cutaneous metastases, derived from pancreatic cancer. METHODS: We treated two patients with cutaneous metastases from pancreatic cancer. We reviewed 40 reported patients in addition to our cases and analyzed clinical features of cutaneous metastases from pancreatic cancer. RESULTS: The median survival time (MST) was 5 mo after diagnoses of cutaneous metastases. The cumulative 2-year survival rate was 3.5%. The most frequent site of cutaneous metastases was the umbilicus. The MST of patients who were treated with chemotherapy or chemoradiotherapy (CRT) was 6.5 mo, which was statistically longer in comparison to patients without treatment. Prognoses of cutaneous metastases are similar to other metastatic sites from pancreatic cancer. Receiving chemotherapy or CRT was the only prognostic factor of cutaneous metastases from pancreatic cancer.CONCLUSION: The prognoses of cutaneous metastases are similar to other metastatic pancreatic cancers. Receiving chemotherapy or CRT was the only prognostic factor of cutaneous metastases from pancreatic cancer.  相似文献

Objective To evaluate the efficacy in the patients with metastatic liver tumor treated with regional therapy of hepatic artery in Cox's regression multivariate analyses.Methods 115 patients with liver metastases were treated by regional therapy of hepatic artery in 274 times. Antitumor agents were selected according to the pathologic results of origin tumor,added embolization with lipiedol ultra-fluid(LUF) or/and gelatin sponge to the patients of hypervascular. Cox regression was used in proportional hazard analysis.Results Cox regression multivariable analyses showed that single lesion,without metastases to the other sites,lesion with hypervascularity, adjuvant chemotherapy after regional therapy of hepatic artery and origination of primary tumor significantly affected the survival time (P<0.05).Conclusion Those of above mentioned are main influence factors in the patients with liver metastases treated by regional therapy of hepatic artery.  相似文献

Glucagonomas are rare neuroendocrine tumors that arise from cells of the pancreatic islets. Most of them are malignant and usually present as metastatic disease. Sites most commonly involved in metastases are the liver and regional lymph nodes. Bone metastases are rare events and only a few cases have been reported in the literature. We present the case of a 53-year-old male with a medical history of recurrent non-functioning glucagonoma. He presented 17 years after the initial diagnosis with new blastic bone lesions involving the T1 vertebra and the sacrum. Diagnostic steps and medical management in metastatic glucagonoma are also reviewed.  相似文献

Objective: To calculate the focus absorption dose of ^153Sm-EDTMP with the Monte Carlo (MC) EGS4 method for treatment of bone metastases from nasopharyngeal carcinoma or breast cancer, and investigate the relationship between the focus absorption dose and painkilling effect of ^153Sm-EDTMP. Methods: Four patients with multiple bone metastases from nasopharyngeal or breast carcinoma and suffered from grade IV bone pain were treated with radionuclide internal irradiation of ^153Sm-EDTMP. The absorption dose and dose distribution of bone metastases and other targeted organs were calculated with MC EGS4 program based on the time-order SPECT/CT scanning and the measurement of the radioactivity in the urine accumulation. The release of bone pain and the improvement of life quality were observed. Results: Bone pain of the patients was significantly alleviated to grade II for 3-4 weeks after internal ^153Sm-EDTMP irradiation. The 3-dimensional absorption dose distribution image of bone metastases and targeted organs showed that the dose distribution in bone metastases was not asymmetrical. After injection of 0.65 × 37 MBq/kg ^153Sm-EDTMP, the highest absorption dose in bone lesions was about 4.9-5.9 Gy, and the dose in the lesion margin was about 2.0 Gy. Using the highest dose as reference dose point, the relative absorption dose values of bone marrow, vertebra and sex organ near lesions were 0.48-1.1 Gy, 0.51-0.85 Gy, and 0.01-0.14 Gy, respectively. Conclusion: The absorption dose of bone metastases is significantly lower than treatment dose of 30 Gy after single irradiation of ^153Sm-EDTMP. The painkilling effect is limited and in accordance with clinical observation.  相似文献

Colorectal carcinoma is one of the most frequent cancers in Western societies with an incidence of around 700 per million people.About half of the patients develop metastases from the primary tumor and liver is the primary metastatic site.Improved survival rates after hepatectomy for metastatic colorectal cancer have been reported in the last few years and these may be the result of a variety of factors,such as advances in systemic chemotherapy,radiographic imaging techniques that permit more accurate determination of the extent and location of the metastatic burden,local ablation methods,and in surgical techniques of hepatic resection.These have led to a more aggressive approach towards liver metastatic disease,resulting in longer survival.The goal of this paper is to review the role of various forms of surgery in the treatment of hepatic metastases from colorectal cancer.  相似文献

Metastatic spread of cervical carcinoma occurs by local extension and lymphatic dissemination, yet distant metastases do occur in advanced stage. The common sites of distant metastases include liver, lung, and bone. However, brain metastases are uncommon. We had 11 patients with brain metastases from cervical carcinoma in recent decade and retrospectively reviewed these cases to study the mechanisms, diagnosis, treatment, and prognosis.

Zusammenfassung: An der Studie zur Wirksamkeit und Anwendungssicherheit von Ketoconazol nahmen 27 Männer im Alter von 20 bis 80 (Median: 57) Jahre, davon 18 mit Onychomykosen und 9 als KontroUen bei den Laborwertbestimmungen, teil. Während des ersten Behandlungsmonats erhielten je 9 Patienten 200 mg und 400 mg Ketoconazol täglich. Danach wurden beide Gruppen 6 Monate mit 200 mg/d weiterbehandelt. Die klinische Beurteilung sowie hämatologische, biochemische und Plasmaspiegeluntersu-chungen erfolgten mindestens monafich, mykologische Untersuchungen wurden vor Aufnahme und bei Beendigung der Therapie vorgenommen. Erne letzte klinische Unter-suchung erfolgte 1 Jahr nach Beginn der Studie. Nach 7 Monaten Behandlung wurden 23 von 30 Nägeln mit “gebessert” bis “stark gebessert” beurteilt, nach dem behandlungsfreien Intervall galt dies für 28 von 30 Nägeln. Die Plasmaspiegel waren mit 200 mg/d ausreichend und uber den Behandlungszeit-raum konstant. Dies spricht für gute orale Resorption und Abwesenheit von Enzyminduktion. Die Laborwerte zeigten im Vergleich zu den Kontrollen und den Werten vor Behandlung keine signifikanten Abweichungen, so daß myelo-, nephro- und hepatotoxische Wirkungen von 400 bzw. 200 mg/d ausgeschlossen werden können. Der Lipidhaushalt wurde nicht beeinfluat und es trat unter Therapie als Folge der Ketoconazolwirkung lediglich Lanosterin im Serum auf. Nach Beendigung der Therapie ging der Lanosteringehalt schnell zurück. Damit erweist sich Ketoconazol in den angewandten Dosen als ein gut verträgliches und zur Langzeitbehandlung von Onychomykosen geeignetes Antimykotikum. Summary: Twenty-seven males with a median age of 57 (range: 20 to 80) years took part in this study on the efficacy and safety of ketoconazole. Eighteen men suffered from onychomycosis; nine served as controls in the safety evaluation. During the first month of treatment, nine patients received 200 mg and the nine other 400 mg ketoconazole daily. Then the treatment was uniformly continued with 200 mg/d for 6 months. Clinical evaluation and haematological, biochemical and plasma level investigations were carried out at least at monthly intervals; mycological controls were performed at the start and end of therapy. A final clinical evaluation was carried out one year after the start of the study. After 7 months of treatment, moderate or definite clinical improvement was obtained in 23 out of 30 nails. After 5 more months without antimycotic treatment this was the case in 28 of 30 nails. Plasma levels obtained with 200 mg ketoconazole daily were adequate and constant during the entire treatment period. This indicates a good oral resorption as well as the absence of induction of hepatic enzymes. The laboratory values did not show significant deviations as compared with the controls or with the pretreatment values. This excludes myelo-, nephro- and hepatotoxic effects of 400 and 200 mg ketoconazole daily. The lipid metabolism was not influenced, the only difference was the occurrence of lanosterol in the serum, which is a result of the mechanism of action of ketoconazole. After the medication period the lanosterol levels subsided rapidly. In the applied doses ketoconazole is a well-tolerated and effective drug for the systemic long-term treatment of onychomycosis.  相似文献

The medically important dematiaceous fungi and their identification   总被引:5,自引:0,他引:5  
Dematiaceous fungi include a large group of organisms that are darkly pigmented (dark brown, olivaceous, or black). In most cases the pigment is melanin, and specifically, dihydroxynaphthalene melanin. The diseases produced include chromoblastomycosis, eumycotic mycetoma, and phaeohyphomycosis. Phaeohyphomycosis is a new classification for a diverse group of previously known entities grouped together on the basis of finding dematiaceous hyphal and/or yeast-like forms in tissue; tissue involvement may be superficial, cutaneous and corneal, subcutaneous, or systemic. Identification of these fungi is based mostly upon morphology. Important structures include annellides (Phaeoannellomyces, Exophiala), phialides (Phialophora, Wangiella), adelophialides (Phialemonium without collarettes, Lecythophora with collarettes), differentiation of conidiophores (Xylohypha versus Cladosporium) and conidial hilum, septation and germination (Bipolaris, Drechslera, Exserohilum). Useful laboratory tests include the 12% gelatin test (controversial), nitrate assimilation (W. dermatitidis is negative, most other species are positive), and determination of temperature maxima (especially 37 degrees C for E. jeanselmei, 40 degrees C for W. dermatitidis and B. spicifera, 42 degrees C for X. bantiana, and 45 degrees C for Dactylaria constricta var. gallopava and Scedosporium inflatum).  相似文献

Summary: Short-term experiments on excised skin (human, pig) gave the following results: 1. In the tissue activity test with direct inoculation (D-TAT) commercial preparations of the non-azole antimycotics ciclopiroxolamine, tolnaftate and naftifine, produced higher inhibitory activity against Trichophyton mentagrophytes (standard strain) in various levels of the horny layer than were produced by the azole antimycotics econazole, miconazole, clotrimazole, oxiconazole and bifonazole. Fast drying solutions of antimycotics invariably gave higher inhibitory activities than creams. In the ultrafiltration tissue activity test (UFT- TAT) against Candida albicans (2 strains), antimycotic agents ranked in order of effectiveness as follows: ciclopiroxolamine – most of the azole antimycotics – bifonazole and naftifine. 2. In tests of fungicidal activity against T. mentagrophytes (2 strains) and Microsporum gypseum (1 strain) the first step was to inoculate the skin surface. After the horny layer had been penetrated by fungal mycelia, antimycotic agents of documented fungicidal potency, chiefly in the form of creams, were applied to the skin surface and left to act for up to 18 hours. The horny layer and epidermis were then scraped off and the concentration of viable fungi was determined. Ciclopiroxolamine cream and lotion produced by far the greatest diminution in viable fungi; creams containing oxiconazole and naftifine were moderately effective and those containing tioconazole and bifonazole produced a relatively small decrease in viable fungi. To avoid erroneous results it is important to homogenize and dilute the skin scrapings; if this is not done certain antimycotics will give misleadingly high fungal killing rates. At this early stage the scatter of results is still wide and minor differences in efficacy cannot as yet be detected with certainty. 3. From the results of various comparative tests it is evident that pig skin can be used as a substitute for human skin in the tests listed under 1. and 2. above. This discovery may make a valuable contribution towards limiting the need for experiments on living animals and trials on human beings. Zusammenfassung: In Kurzzeitversuchen an exzidierter Haut (Mensch, Schwein) wurde gefunden: 1. Im Gewebeaktivitätstest mit direkter Inokulation (D-GAT) wurde mit Handelspräparaten der Nichtazol-Antimykotika Ciclopiroxolamin, Tolnaftat und Naftifin in verschiedenen Hornschichtniveaus eine höhere Hemmaktivität gegenüber Trichophyton mentagrophytes (Standard-Stamm) erzielt als mit solchen der Azol-Antimykotika Econazol, Miconazol, Clotrimazol, Oxiconazol und Bifonazol. Rasch trocknende Lösungen von Antimykotika ergaben durchweg höhere Hemmaktivitäten als Cremes. Im Ultrafiltrations-Gewebeaktivitätstest (UFT-GAT) gegenüber Candida albicans (2 Stämme) ergab sich nach erzielter Wirksamkeit die Rangfolge Ciclopiroxolamine – Mehrzahl der Azolantimykotika – Bifonazol und Naftifin. 2. In Fungizidie-Testen gegenüber T. mentagrophytes (2 Stämme) und Microsporum gypseum (1 Stamm) wurde zunächst die Hautoberfläche inokuliert. Nach Durchdringung der Hornschicht mit Pilzmyzelien wirkten auf die Hautoberfläche bis zu 18 Stunden lang überwiegend Cremes von als fungizid publizierten Antimykotika ein. Während sich in abgeschabter Hornschicht und Epidermis der so bearbeiteten Hautoberflächen mit Ciclopiroxolamin-Creme und -Lotion die weitaus höchste Verminderung lebensfähiger Keime ergab, bewirkten Cremes mit Oxiconazol und Naftifin eine mittlere und solche mit Tioconazol und Bifonazol eine relativ niedrige Keimeliminierung. Zur Vermeidung von fehlerhaften Ergebuissen mußten Homogenisierung und Verdünnung der Hautschabsel erfolgen, anderenfalls bei mehreren Antimykotika eine zu hohe Keimabtötung vorgetäuscht worden wäre. Wegen der vorerst noch hohen Streuung der Ergebnisse können kleinere Wirksamkeitsunterschiede noch nicht sicher erfaßt werden. 3. Nach dem Ergebnis verschiedener Vergleichstests kann in den Testen zu 1. und 2. Schweinehaut als Ersatz für Haut vom Menschen dienen und dürfte damit wesentlich zur Einschränkung von Versuchen am lebenden Tier und von Prüfungen am Menschen beitragen.  相似文献

Mycotic keratitis in Paraguay   总被引:7,自引:0,他引:7  
Patients with corneal ulcer, residing mainly in rural areas of Paraguay, were controlled for mycotic eye infections. In 26 cases out of 45 (58%) presence of filamentous fungi was observed (Fusarium sp. (11), Aspergillus sp. (5), Cladosporium sp. (3), Alternaria sp. (2), Acremonium sp. (1), Curvularia sp. (1), culture negative (3)). In 17 cases also pathogenic bacteria were present. Most of the patients were farmers and belonged to the low income class. These data indicate that mycotic keratitis may be a frequent cause for eye infections in developing countries.  相似文献

Mycotic immunodiagnosis was performed in 186 hospitalized patients with different respiratory diseases, mostly considered as tuberculosis and others with a doubtful diagnosis. Crude histoplasmin, coccidioidin, paracoccidioidin, blastomycin, candidin, aspergillin, and sporotrichin, as well as purified polysaccharide-protein complexes (PPC) of Histoplasma capsulatum, Coccidioides immitis, and Paracoccidioides brasiliensis were used as antigens. Immune tests used included skin test (ST), gel immunodiffusion (ID), counterimmunoelectrophoresis (CIE), complement fixation (CF), and ELISA. A possible association with candidosis was observed in 17% of patients with tuberculosis and diabetes; one presumptive paracoccidioidomycosis, one confirmed aspergillosis, and six cases of active histoplasmosis were determined. Candidin ST showed 29% of positive reactions with an increased frequency in patients between 31 and 55 years of age. CF test showed the highest positivity percentages with crude antigens, specially for Candida antigen (26.3%) and histoplasmin (18.2%). Cross reactions were evident with crude antigens but decreased when PPC's were used in ELISA.  相似文献

Infection ability tests of four species of the Saprolegniales viz., Brevilegnia subclavata Couch, Geolegnia inflata Coker & Braxton, Protoachlya oryzae Khulbe and Scoliolegnia centrica Khulbe were made by artificial inoculation experiments. Except Geolegnia inflata, all the three species parasitized the test fishes (Carassius auratus L., Puntius conchonius Ham., P. ticto Ham. and Nemacheilus rupicola). Two chemicals, namely boric acid and potassium permanganate were effective at 0.1 to 0.15 M concentrations against parasitic watermolds.  相似文献

Summary. A total of 54 patients with culturally proven tropical dermatomycoses, comprising 23 with various types of dermatophytoses, one with foot infection due to Trichosporon beigelii and one with foot infection due to Geotrichum candidum , two with candidoses of the groin and 27 with pityriasis versicolor, were included in a clinical trial of efficacy of 1% isoconazole cream (TravogenR, Schering, Berlin, Germany). Five patients were not evaluable. A clinical and mycological cure was achieved in 29 cases in 3–4 weeks. In 15 (31%) of the remaining patients treatment was required for 5–6 weeks, while another three patients required treatment for 8 weeks. In two patients the disease proved to be resistant to treatment with the drug.
Zusammenfassung. Insgesamt 54 Patienten mit kulturell gesicherter Dermatomykose, (23 unterschiedliche Dermatophytosen, eine Trichosporon beigelii - und eine Geotrichum candidum -Fußinfektion, 2 Candidosen der Leistengegend und 27 Pityriasis versicolor) wurden in einer klinischen Wirksamkeits-studie mit 1% iger Isoconazol-Creme (TravogenR, Schering, Berlin, Deutschland) behandelt. Fünf Patienten waren nicht auswertbar. Eine klinische und mykologische Heilung wurde bei 47 von 49 Patienten (96%) erreicht. Bei 29 patienten (59%) wurde die Heilung bereits nach 3–4 Wochen Behandlung erreicht. Weitere 15 Patienten (31%) benötigten 5–6 Wochen und drei Patienten 8 Wochen Behandlungsdauer. Zwei Mykosesituationen erwiesen sich als therapieresistent.  相似文献

Zusammenfassung. Im Hinblick auf die Reproduzierbarkeit können zwischen dem Etest® und der NCCLS-Methode keine gravierenden Unterschiede festgestellt werden. Bei der Frage der klinischen Korrelation existieren bisher nur Einzelbeobachtungen. Die Korrelation der Teste untereinander ist als Erreger- und Testsubstanz-abhängig bekannt. Die einfachert Handhabbarkeit prädisponiert den Etest® für die Routine. Bevor der Etest® für die Empfindlichkeitsprüing von Hefen uneingeschränkt empfohlen werden kann, sind weitere Evaluierangen erforderlich. Auch für das NCCLS-Verfahren steht eine Validierung noch aus. Andere Verfahren werden sich an diesen beiden Testsystemen messen müssen.
Summary. The Etest® and the NCCLS method are not much differing in respect to their reproducibility. Only single observations exist on the clinical correlation of both tests. The correlation between both tests are known as being dependent on the yeast species and antifungals used. Due to the easy and simple handling the Etest® is attractive for routine laboratories. The Etest® has to be more evaluated before it can be generally recommended. The NCCLS method also is not validated until now. Different test methods should be compared thoroughly with the above mentioned standard.  相似文献
