Pulmonary alveolar microlithiasis. Report of a case 总被引:1,自引:0,他引:1
52.
39 consecutive cases of plantar ulcers with underlying chronic osteomyelitis admitted in the Sacred Heart Hospital during 1975/1976 were studied for the infecting organisms and their sensitivity to easily available antibiotics. Single organism was iasolated in only 10 cases, the infection in the rest being a mixed one. The commonest organisms were Staphylococcus, Streptococcus and Proteus mirabilis. In a few cases Pseudomonas and E-Coli were also isolated. Chloramphenicol was the most effective antibiotic in general and Streptomycin the least. 70% of the staphylococcus strains isolated were found to be resistant to Penicillin. Empirical use of antibiotics especially Penicillin and Streptomycin is hence deprecated. 相似文献

Familial lichen amyloidosis. Report of 19 cases in 4 generations of a Chinese family in Malaysia 总被引:1,自引:0,他引:1
Summary.— Nineteen members in 4 successive generations of one Chinese family in Malaysia were found to have classical lichen amyloidosis without systemic amyloid involvement. The disease was transmitted as an autosomal dominant trait with variable penetrance. Sex ratio was equal and the onset was around the age of puberty. The extent and severity of the lesions tended to increase with age. No patient subsequently developed the systemic form of amyloidosis. The present findings further strengthen the genetic theory of lichen amyloidosis. 相似文献

Does bioequivalence between modified cyclosporine formulations translate into equal outcomes? 总被引:2,自引:0,他引:2
Taber DJ Baillie GM Ashcraft EE Rogers J Lin A Afzal F Baliga P Rajagopalan PR Chavin KD 《Transplantation》2005,80(11):1633-1635
Neoral was replaced with a generic cyclosporine formulation on our hospital formulary. We compared outcomes for de novo kidney transplant recipients who either received Gengraf (n=88) or Neoral (n=100) in a single-center, retrospective review. As compared to patients who received Neoral, patients who received Gengraf were significantly more likely to have an acute rejection episode (39% vs. 25%, P=0.04), more likely to have a second rejection episode (13% vs. 4%; P=0.03), or to have received an antibody preparation to treat acute rejection (19% vs. 8%; P=0.02). Patients treated with Gengraf had a higher degree of intrapatient variability for cyclosporine trough concentrations as determined by %CV (P<0.05). The incidence of acute rejection at 6 months posttransplant was significantly higher in patients who received Gengraf compared to Neoral. A larger, prospective analysis is warranted to compare these formulations of cyclosporine in de novo kidney transplant recipients. 相似文献

Comparative study on density gradients and swim-up preparation techniques utilizing neat and cryopreserved spermatozoa 总被引:6,自引:0,他引:6
AIM: To 1) compare post-wash and post-thaw parameters of sperm processed with PureSperm density gradient technique and swim-up method; and 2) test the efficacy of two commonly available density gradient media PureSperm and ISolate. METHODS: This prospective study used semen specimens from 22 patients. Specimens from nine patients were processed by both PureSperm density gradient and swim-up method. These specimens were then cryopreserved. Thirteen specimens were processed by both PureSperm (40 % and 80 %) and Isolate (50 % and 90 %) double density gradient techniques. The two fractions processed by both PureSperm and swim-up were analyzed for post-wash sperm characteristics. Post-thaw analysis was done after 24 hours. Sperm fractions obtained after processing with PureSperm and ISolate were compared for post-wash sperm characteristics and ROS levels. Results: Specimens prepared with PureSperm had significantly higher median total motile sperm counts (TMSC) (32.2 x 10(6) vs. 17.6 x 10(6)), recovery rates (69.2 % vs. 50.0 %), and longevity at 4 hours (83.0 % vs. 55.0 %) compared to specimen prepared by swim-up. Post-thaw specimens also had a higher recovery and longevity at 4 hours with PureSperm as compared to the swim-up. Semen specimens processed by PureSperm had significantly higher total sperm count, TMSC, and percentage recovery rates (30.0 % vs. 19.7 %) than ISolate. CONCLUSION: Semen quality is better preserved in fresh and cryopreserved semen prepared with PureSperm density gradient compared to swim-up. A significant enrichment of sperm is observed with PureSperm compared to ISolate. Higher recovery rates of mature motile sperm obtained after PureSperm sperm preparation may be beneficial for successful ART. 相似文献

Identifying high-risk asymptomatic diabetic patients who are candidates for screening stress single-photon emission computed tomography imaging 总被引:6,自引:0,他引:6

OBJECTIVES: The purpose of this study was to identify which asymptomatic diabetic patients are candidates for screening single-photon emission computed tomography (SPECT) imaging and to examine angiographic findings and mortality in patients according to SPECT imaging categories. BACKGROUND: Previously we reported a high percentage of abnormal and high-risk SPECT imaging scans in asymptomatic diabetic patients. METHODS: We examined the associations between several clinical and laboratory variables and a high-risk stress SPECT imaging scan in 1,427 asymptomatic diabetic patients without known coronary artery disease (CAD). Results of coronary angiography and long-term outcome were also analyzed. RESULTS: An abnormal stress SPECT imaging scan was present in 826 patients (58%) and a high-risk scan in 261 patients (18%). Multivariate analysis demonstrated that seven variables were independently associated with a high-risk scan (model chi-square=107, p <0.0001). The two most important variables were electrocardiogram (ECG) Q waves (adjusted chi-square=38.3, p <0.001) and peripheral arterial disease (PAD) (adjusted chi-square=13.9, p <0.001). Coronary angiography was performed in 127 (49%) high-risk SPECT imaging patients, 61% of whom had angiographic high-risk CAD. Annual mortality rates for patient subsets categorized by SPECT imaging scans were high-risk 5.9%, intermediate-risk 5.0%, and low-risk 3.6% (p <0.001 for differences between groups). CONCLUSIONS: High-risk findings on stress SPECT imaging were present in 18% of asymptomatic diabetic patients without known CAD. Patients with high-risk scans had a high prevalence of severe CAD and a high annual mortality rate. ECG Q waves and/or evidence of PAD identified the most suitable candidates for screening. 相似文献

AIM: The current study was undertaken to assess the effect of ethanol and thermally oxidized sunflower oil ingestion on liver phospholipid fatty acids and the protective role of Cuminum cyminum L. METHODS: Ethanol was administered at a level of 20% and thermally oxidized sunflower oil at a level of 15% for 45 days. C. cyminum was administered at a dosage of 250 mg/kg body weight for 45 days. We investigated the changes in the liver phospholipid fatty acid composition. RESULTS: Ethanol and thermally oxidized sunflower oil administration modifies the fatty acid composition and the analysis of fatty acids showed that there was a significant increase in the concentrations of 16:0, 16:1, 18:0, 18:1 and 18:2, whereas the concentration of 20:4 was significantly decreased. The concentrations of 16:0, 16:1, 18:0, 18:1 and 20:4 were near normal in cumin-treated rats. CONCLUSION: The present investigation shows that cumin prevents the changes in the composition of fatty acids, which were produced by ethanol and thermally oxidized oil. 相似文献

OBJECTIVE: To examine the outcome of assisted reproduction techniques (ART) using cryopreserved semen from patients with cancer. DESIGN: Prospective. SETTING: Therapeutic semen banking program at a tertiary healthcare center. PATIENT(S): Twenty-nine men with cancer who cryopreserved their sperm before treatment at our facility from 1982 to 2001 and withdrew their samples for assisted reproduction (IUI, IVF, or intracytoplasmic sperm injection [ICSI]). INTERVENTION(S): Sperm bank records were used to identify the patients. Information on fertility potential indices was obtained from medical records and through interviews. Of the 29 patients, 9 had testicular cancer, 12 had Hodgkin's disease, and 8 had other types of cancer. MAIN OUTCOME MEASURE(S): Pregnancy and live births. RESULT(S): A total of 87 ART cycles (42 IUI, 26 IVF, and 19 ICSI) was performed. Of those cycles, 18.3% resulted in pregnancy (7% IUI, 23% IVF, and 37% ICSI), and 75% of the pregnancies resulted in a live birth (100% IUI, 83% IVF, and 57% ICSI). There was no significant difference in the outcomes when the results were stratified by type of ART and malignancy. None of the 11 infants who were born had congenital anomalies. CONCLUSION(S): Our findings emphasize the need for physicians to discuss the issue of semen cryopreservation with all men of reproductive age who have cancer before antineoplastic therapy is started. 相似文献

We report the final results of the trial comparing the Amplatz thrombectomy device (ATD) with surgical thromboembolectomy (ST) to declot thrombosed dialysis access grafts (DAG). The study population consisted of 174 DAG, 109 of which were randomized to mechanical thrombectomy using the ATD and 65 of which were randomized to conventional surgical thromboembolectomy. Forty grafts were re-enrolled in the trial when they failed beyond the 90 days follow-up after the initial treatment. Thirty-one were re-enrolled for mechanical thrombectomy and nine were re-enrolled for surgical thrombectomy, resulting in a total of 140 ATD procedures and 74 surgical thromboembolectomy. Immediate thrombectomy success was defined as greater than 90% thrombus removal followed by the ability to dialyze after treatment, and analysis of long term success based on graft patency at 30 and 90 days, with successful dialysis. Immediate thrombectomy success with the ATD procedure was achieved in 79.2% and with ST in 73.4%. Patency of the graft, with successful dialysis, at 30 days with the ATD procedure was 79.2% and with ST was 73.4%. Patency of the graft, with successful dialysis, at 90 days with the ATD procedure was 75.2% and with ST was 67.8%. The data collected in this study provided a prospective comparison of mechanical thrombectomy with the ATD and ST performance in thrombosed DAG. The results of the performance of both methods were comparable. No statistically significant differences were seen.List of Investigators: Carol C.
