AIM: The application of cardiopulmonary bypass to atrial involvement represents an important advance that has improved the safety and technical efficacy of a difficult surgical undertaking. Our experiences of the management of extended thrombi into the right atrium in patients with retroperitoneal malignancy using a cardiopulmonary bypass were discussed. METHODS: Data were reviewed for five patients (two men and three women; mean age, 60.4 years; range, 49-79 years) with retroperitoneal tumors displaying intracardiac tumor extension. Tumors originated in the right kidney in four patients, and in left adrenal gland in one patient. Cardiopulmonary bypass was used in all cases. RESULTS: Mean total blood loss was 6059 mL. Mean operative time was 14.7 h. No intra- or postoperative complications due to surgical technique were encountered, and no significant bleeding occurred during incision of the inferior vena cava or after removal of tumor thrombus. The follow-up period ranged from 3 to 20 months with a mean of 12.6 months. Of the five patients, three died of metastatic diseases, one died of liver dysfunction and one remains disease free as of 18 months postoperatively. CONCLUSIONS: Our experience indicates that this procedure can be safely used for atrial involvement. Although superior long-term survival cannot be shown yet, favorable early results and a lack of perioperative complications were identified. 相似文献

BACKGROUND: The roles of several foods and beverages in the development of bladder cancer remain unclear. METHODS: We undertook a hospital-based case-control study at Aichi Cancer Center Hospital, Japan. Subjects included 124 men and women (bladder cancer cases) with newly diagnosed cancers of the renal pelvis (n = 5), ureter (n = 6) or bladder (n = 113) and 620 age- and sex-matched, cancer-free outpatients (controls) presenting at the hospital in the period from 1994 to 2000. Smoking-adjusted odds ratios (OR) were estimated to assess the strength of associations between self-reported intake of foods or drinks and bladder cancer risk, using conditional logistic models. RESULTS: We found a decreased risk in relation to frequent intake of green-yellow vegetables; the OR for the highest intake score compared with the lowest was 0.54 (95% confidence interval [CI] 0.29-0.99). The OR for carrot intake of >/=5 times/week compared with =1-3 times/month was 0.41 (95% CI 0.16-1.01) and a decreasing risk with increasing consumption of green vegetables was also detected (P for trend = 0.063). Inverse associations between black tea, eggs and meat and risk were also suggested, whereas moderate drinkers of green tea (5-9 cups/day) showed an elevated risk. Coffee and milk consumption did not appear to exert any influence. CONCLUSIONS: Those with an increased risk of bladder cancer, such as smokers, may benefit from increasing their consumption of green-yellow vegetables. 相似文献

We report on a successful treatment of hypoplastic bladder in a 5-month-old girl with single ectopic ureter in a solitary kidney. Side-to-side anastomosis was performed first between the urethral ectopic ureter and side wall of the bladder. Nine months later when the bladder capacity increased to 70 ml, ureterocystoneostomy was done through psoas hitch procedure. She retains urine of about 270 ml and evacuate completely at 14 years of age. 相似文献

We report the first case of malignant retroperitoneal tumor arising in a multicystic dysplastic kidney of an 8-year-old girl with Schinzel-Giedion syndrome. Although conservative treatment has been regarded as the standard management for asymptomatic multicystic dysplastic kidney, prophylactic surgical removal should be considered for selected children with potential risk of malignancy. 相似文献

Abstract A case is described of a patient with limb shaking in whom anticonvulsant therapy was effective for inhibiting attacks. A 70 year old female developed rhythmical involuntary limb shaking of the right upper and lower limb in April 1986. She was diagnosed as having transient ischemic attacks and was followed up under treatment with an antiplatelet drug. Subsequently, anticonvulsant therapy was also initiated on an outpatient basis. In August 1991, she was admitted with shaking of the right upper and lower limbs. Low molecular dextran was ineffective for inhibiting limb shaking attacks, but intravenous injection of diazepam was effective. Phenytoin and phenobarbital was used in combination. No limb shaking attacks occurred thereafter. The involuntary movement was the same as that observed at the onset of the disease. Though no changes were observed in the pattern of the involuntary movement, anticonvulsant therapy was effective in preventing and inhibiting attacks. This finding is inconsistent with previous reports. It is possible that epileptic factors are involved in the development of this condition. 相似文献

Serum anti-streptolysin-O antibody (ASO) and anti-streptococcal polysaccharide antibody (ASP) of IgA, IgG and IgM classes were measured using an enzyme-linked immunosorbent assay in 41 children with IgA nephropathy (Group A), 15 children with uncomplicated anaphylactoid purpura (Group B) and 13 children with purpura nephritis (Group C). The serum concentrations of the IgA, IgG and IgM classes were measured by single radial immunodiffusion. When compared with sex- and age-matched controls, the concentrations of serum IgA (but not of IgG or IgM) were significantly increased in the three groups studied. The titers of ASO of the IgA and IgM classes, and those of ASP of the IgA and IgG classes, were significantly increased in Group A. In Group B, only the ASP titers of the IgA class were significantly increased. No significant difference was noted in the titers of either ASO or ASP of any class in Group C. Thus, increased antibody response in IgA nephropathy is not restricted to IgA. Anaphylactoid purpura with or without renal disease appears to be different in its humoral anti-streptococcal response from IgA nephropathy. 相似文献

Summary. Chromosomal translocations involving band 3q27 are recently described common specific cytogenetic abnormalities in B-cell neoplasms, and the BCL-6 gene, identified on 3q27, was shown to be disrupted and over-expressed in lymphoma cells having these chromosomal translocations. In the present study we found rearrangements within the BCL-6 gene in seven out of 3 5 cases with B-cell non-Hodgkin's lymphoma (NHL). Further analysis revealed that three of these patients with BCL-6 abnormality had multiple rearranged bands hybridized with probes from a single restriction fragment within the major translocation cluster (MTC). suggesting that independent DNA rearrangements would occur on both alleles. Additionally, Southern blot analysis indicated that three patients carry deletions encompassing the area containing the first exon of the BCL-6 gene. Our results suggest that biallelic DNA rearrangements and deletions would occasionally occur in NHL patients with BCL-6 abnormality. 相似文献

PURPOSE: To determine whether additional, far lateral cores improve the diagnostic performance of transrectal sextant biopsy in men with large prostate glands. METHODS: Men with prostate volumes of 50 mL or greater in transrectal ultrasonography who were suspected of prostatic adenocarcinoma were prospectively enrolled. Biopsy criteria were defined as 2.0 ng/mL or greater of serum total prostate-specific antigen and/or abnormal findings on digital rectal examination. Four cores of far lateral biopsies were added to the standard sextant technique. RESULTS: Of 104 patients enrolled in the present study and undergoing biopsy, 14 (13.5%) were diagnosed as having prostate cancer and 27 (26.0%) were diagnosed as having prostatic intraepithelial neoplasia (PIN) or an atypical gland. There were no cases where cancer was only detected in the additional cores, whereas PIN/atypical gland was uniquely detected from the additional, far lateral sites in eight of the 27 patients who were diagnosed with this condition. CONCLUSIONS: Although the number of patients diagnosed as having PIN/atypical gland might increase with the addition of far lateral cores, this additional sampling does not improve cancer detection rates in men with large prostate glands. 相似文献

Performing vesicourethral anastomosis following retropubic radical prostatectomy may, under some anatomical conditions, be difficult. We describe the use of a new suturing semiautomatic device for deep surgical operations (Maniceps) to facilitate vesicourethral anastomosis. Maniceps is a pair of forceps both jaws of which have a groove at the tip. A 7 mm straight needle is set on the needle-holder jaw. By closing and reopening the forceps, the needle is moved onto the needle-receiver jaw. The use of Maniceps in vesicourethral anastomosis ensure the procedure is safe, easy and effective. 相似文献
