The objective of this study was to evaluate the possible role of transforming growth factor beta 1 (TGF-beta1) antibodies (ab) for the prevention of fibrotic effects of priapism in a rat model. In total, 30 adult Sprague-Dawley rats were divided into five groups. Priapism with 6 h (group 1), priapism with 6 h+ab (group 2), priapism with 24 h (group 3), priapism with 24 h+ab (group 4) and control (group 5). Priapism was induced with a vacuum erection device and a rubber band was placed at the base of the erect penis. At 1 h after the initiation of priapism, TGF-beta1 antibodies were given intracavernosaly. All rats underwent electrical stimulation of the cavernous nerve after 8 weeks. Intracavernous and systemic blood pressures were measured during the procedure. Rats in group 1 showed significantly higher (intracavernosal pressure (ICP) pressures to cavernous nerve stimulation and had higher ICP/BP ratios when compared to other groups. Similarly, histopathologic examination revealed less fibrosis in group 2, compared with the other groups. Consequently, TGF-beta1 antibodies antagonise the fibrotic effects of TGF-beta1, especially in cases with duration of priapism less than 6 h. 相似文献

Post-transfusion graft-versus-host disease (PT-GVHD) is seldom, but it has a high mortality rate, exceeding 90 percent. There is no standard treatment for PT-GVHD and irradiation of blood and its components before transfusion is broadly accepted for the prevention of PT-GVHD. In this report we present a case (a 17-year-old female) of PT GVHD, who died in spite of the use of all available therapeutic options. 相似文献

Turkey is located in a geographic area of the world where thalassemia syndromes and abnormal hemoglobins are common. In this study we aimed to evaluate the thalassemia syndromes and abnormal hemoglobins in patients from the Aegean region of Turkey. Among the patients admitted to our Pediatric Hematology or Hematology Clinic between January 1997-September 1999, hemoglobin electrophoresis of 3,228 cases investigated for anemia was done using high performance liquid chromatography. Beta thalassemia trait was diagnosed in 21.1%, beta thalassemia major in 0.2%, S-beta thalassemia in 0.37%, Hb D in 0.37%, Hb S trait in 0.32%, Hb E in 0.18%, Hb O-Arab in 0.12%, Hb G-Copenhagen in 0.09%, Hb D-Iran in 0.06%, Hb Lepore in 0.06%, Hb Hasharon in 0.03%. Our results demonstrate that people in the Aegean region of Turkey have a wide spectrum of thalassemia syndromes and abnormal hemoglobins. 相似文献

OBJECTIVE: To describe an atypical waveform, termed an abnormal positive potential (APP), on round window electrocochleograms (RW ECochG) of children and to relate its occurrence to clinical history. STUDY DESIGN: APPs were identified prospectively, and a retrospective analysis was made of these patients' clinical histories, audiograms, and auditory outcomes (hearing aid, cochlear implant, or nonauditory communication) SETTING: Tertiary referral teaching hospital, day surgery and clinics. PATIENTS: All 431 children <110 months of age suspected of a severe to profound hearing loss who underwent RW ECochG from January 1993 to August 1997. INTERVENTION: Diagnostic RW ECochG for auditory threshold estimation. MAIN OUTCOME MEASURE: The presence on the RW ECochG of the APP: an early positive potential in the absence of a compound action potential (CAP). RESULTS: An APP was observed in 34 children. The APP was most marked in response to clicks and 8-kHz tones. The APP click threshold averaged 70 dB hearing loss. The brainstem evoked potential of these children showed an absence of waves, or a broad positive wave with no subsequent waves. Twenty-nine of 30 behavioral audiograms obtained were indicative of severe to profound hearing loss. Auditory outcomes were available from 26 children; 45% of them derived no help from a hearing aid, and 8 children received a cochlear implant. Clinical factors frequently associated with APP were prematurity in combination with kemicterus or hypoxia. CONCLUSIONS: APP thresholds were lower than neural thresholds or behavioral thresholds. Children with APP need close follow-up, because half of those studied needed nonauditory strategies to develop effective communication. 相似文献

OBJECTIVE: To compare the maturation of the auditory pathway, as shown by electrical brainstem auditory potentials (EABRs), in ears with and without prior auditory stimulation. MATERIAL AND METHODS: Electrophysiological data were collected prospectively from ears which had received cochlear implants. Implant-evoked (Imp)EABRs were recorded. Thirty children, implanted after January 2000, were selected according to a strict inclusion/exclusion protocol. All the children had received a 22-channel Nucleus cochlear implant (CI24 series). Intraoperatively, ImpEABRs were recorded using the Medelec Synergy Evoked Response system in conjunction with Nucleus Neural Response Telemetry software. The ImpEABR latencies of waves eII, eIII and eV and the morphology of wave eV were assessed. RESULTS: ImpEABRs alter during the first 12 months of life. The latency becomes shorter during this period and the morphology of wave eV alters from a broad shape to a more distinct waveform. This appears to occur independently, even in the absence of auditory stimulation. CONCLUSION: The development of electrical brainstem auditory potentials is not dependent on auditory stimulation. 相似文献

A 3 year-old girl presented with a 6- months history of facial swelling in the region of cheek. Physical examination revealed a firm, non-tender, non- erythematous, mobile, 3 × 3 cm mass in the right cheek. Fine needle aspiration biopsy of the mass demonstrated significiant mitotic activity, slight pleomorfism and atypical cells. A transoral incisional biopsy was also done for accurate diagnosis and the tumor was diagnosed as sialoblastoma. After performing superficial parotidectomy, the tumor was excised with large margins. No adjuvant treatment was given and no recurrence has been noted after 6 months. Despite the rareness of the disease, pathologists and otolaryngologists should always consider the possibility of sialoblastoma of salivary glands in childhood and it can be best described as locally agressive with malignant potential. 相似文献

Recent phase III trials have proven the fact that adding bevacizumab to irinotecan plus infusional 5-fluorouracil (5-FU)/leucovorin (LV) should be preferred as a first-line treatment for metastatic colorectal cancer (mCRC). But, since the data regarding bevacizumab administered together with capecitabin, an oral fluoropyrimidine, and irinotecan in patients with mCRC is limited, we aimed to analyse the efficacy and safety of bevacizumab with capecitabine plus irinotecan (BEV-CAPIRI) regimen in mCRC patients. Records of patients treated with BEV-CAPIRI regimen between January 2005 and March 2008 were reviewed. Efficacy data regarding response rates (RR) as well as safety data were collected. Progression free survival (PFS) and overall survival (OS) analyses were done by using the Kaplan–Meier method. A total number of 53 metastatic colorectal cancer patients were treated with BEV-CAPIRI regimen. The median age of this population was 57.3 ± 11.5 (range 29–78). The treatment was well tolerated. The RR was 43.3%, while 30.1% of the patients achieved stable disease (SD). Median PFS and OS were 12.6 ± 1.4 and 20.6 ± 1.7 months, respectively. However, median OS was 21.3 months for male and 14.6 months for female patients. In addition, median OS and PFS was 25.3 months and 16.2 months for the patients who received BEV-CAPIRI as first-line treatment, respectively, and for the other patients it was 15.2 months and 10.2 months, respectively. In conclusion, BEV-CAPIRI is an effective and well-tolerated alternative regimen for mCRC, leading to disease control in a vast majority of patients with mCRC. 相似文献

BACKGROUND: Topotecan has been emerged as a new promising anticancer drug for patients with ovarian cancer. METHODS: In this study, patients who were treated with topotecan were reviewed retrospectively. A total of 26 patients was included the study. All patients had received platinum-based regimens previously. Topotecan was administered a dose of 1.5 mg/m(2) intravenously 30 min daily for 5 days and repeated every 21 days. RESULTS: The response rates were 30% by CA-125 level and 29% in clinic evaluation. Median duration of response was 8 (3-15) months, median progression-free interval was 12 (4-30) months and median overall survival was 15 (4-36) months. Grade 3-4 neutropenia occurred in 58% of the patients (38% of the courses) and trombocytopenia in 29% of the patients (12% of the courses). Nonhematological toxicities were mild. There was no drug-related death. CONCLUSION: Topotecan is considered as a reasonable option for treatment of patients with platinum refractory recurrent ovarian cancer. 相似文献
