We estimated the usefulness of a mixture of N-butyl-2-cyanoacrylate (NBCA) with lipiodol for transcatheter arterial embolization (TAE) used to control massive bleeding from gastric or duodenal ulcer. Thirty patients who had gastric or duodenal ulcers and massive bleeding that was uncontrollable by endoscopic procedures were included in this study. All patients were subjected to TAE (without NBCA in 23 and with NBCA in seven patients). Coils and/or gelfoam were also used. The achievement of haemostasis, occurrence of rebleeding and the time taken for TAE were compared between patients who received TAE without and with NBCA. Eighteen of 23 patients (78.3%) who received TAE without NBCA and six of seven patients (85.7%) who underwent TAE with NBCA achieved complete haemostasis without rebleeding. The time for TAE was significantly shorter in patients who received NBCA compared with those who did not (P= 0.0095). TAE using NBCA or a combination of NBCA and coils achieved a rapid, complete embolization regardless of vascular distribution or arterial diameter. Thus NBCA is considered to be useful as a secondary embolization material in TAE that is urgently conducted to control massive bleeding from gastric or duodenal ulcers. 相似文献

The continuous intravenous administration of l-(2-tetrahydrofuryl)-5-fluorouracil(FT) to colorectal cancer patients was studied in regard tothe stability of FT in intravenous hyperalimentation (IVH) solutionsand tumor levels of 5-fluorouracil (5-FU). FT was very compatiblewith IVH solutions, because the decomposition of FT in IVH solutionwas very low, 3%. High levels of 5-FU, which is an active metaboliteof FT, were obtained in the tumors, averaging 0.369 mcg/g. Theratios of 5-FU levels in the tumor to those in serum and normaltissues were 13.6 and 3.7. respectively. The difference in 5-FUlevels between normal tissues and the tumors was statisticallysignificant (P<0.01). Therefore, continuous intravenous administrationof FT should be widely used to treat patients with colorectalcancer, as the method of administration of antitumor agents. 相似文献

For an accurate assessment of jaw movement, it is crucial to understand the comprehensive formation of the masticatory muscles with special reference to the relationship to the disc of the temporomandibular joint. Detailed dissection was performed on 26 head halves of 14 Japanese cadavers in order to obtain precise anatomical information of the positional relationships between the masticatory muscles and the branches of the mandibular nerve. After complete removal of the bony elements, the midmedial muscle bundle in all specimens and the discotemporal muscle bundle in 6 specimens, derivatives of the temporalis, which insert into the disc were observed. On the anterior area of the articular capsule and the disc of the temporomandibular joint, the upper head of the lateral pterygoid, the midmedial muscle bundle of temporalis and the discotemporal bundle of temporalis were attached mediolaterally, and in 3 specimens the posterosuperior margin of the zygomaticomandibularis was attached to the anterolateral area of the disc. It is suggested that these muscles and muscle bundles contribute to various mandibular movements. Although various patterns of the positional relationships between the muscles and muscle bundles and the their innervating nerves are observed in the present study, relative positional relationships of the muscles and muscle bundles and of nerves of the mandibular nerve are consistent. A possible scheme of the developmental formation of the masticatory muscles based on the findings of the positional relationships between the muscles and the nerves is presented. 相似文献

High-dose intravenous (IV) metoclopramide has shown efficacywith few side effects for the treatment of nausea and vomitingon the day of cisplatin administration. From November 1984 toJanuary 1986, two randomized trials in an antiemetic study wereconducted. In trial I, the antiemetic effect of a short courseof high-dose dexamethasone was compared with that of high-dosemetoclopramide in 29 patients with lung cancer receiving chemotherapycon taining cisplatin (80 mg/m2 IV) in a randomized controlledtrial. Dexamethasone was given IV at a dose of 16 mg 1/2 hrbefore and 8 mg, 1 1/2, 3 1/2 and 5 1/2 hr after cisplatin.Metoclopramide was given IV at a dose of 2 mg/kg, 1/2 hr beforeand 1 1/2, 3 1/2 and 5 1/2 hr after cisplatin. Major emeticcontrol (02 episodes of vomiting) during the 24 hr aftercisplatin administration was achieved in 55% (6/11) and 67%(12/18) of the patients receiving dexa methasone and metoclopramide,respectively, without serious toxicity. The dura tion of nauseaor anorexia was similar for the two treatment groups. In trial11, the combination of metoclopramide and dexamethasone wascompared with metoclopramide alone to assess the additive antiemeticeffect of the two drugs in 23 patients with lung cancer receivingcisplatin at a dose of 120 mg/m IV in a randomized cross-overstudy. A major antiemetic response was observed in 27% (3/11)and 92% (11/12) of the patients receiving metoclopramide aloneand metoclopramide plus dexamethasone, respectively (p <0.005). The duration of nausea and anorexia was similar forthe two treatment groups. Pa tients tended to prefer the combinationof metoclopramide and dexamethasone; however, the differencewas not statistically significant (p = 0.14) in the small numberof patients entered in this study. Despite excellent controlof acute chemotherapy-induced emesis, 45% of 52 patients experienceddelayed nausea and vomiting more than 24 hr after cisplatinadministration even among those who had had an excellent short-termresponse to the antiemetic agents. 相似文献

A dual chamber pacemaker having a fallback (FB) mode was utilized in nine patients with sick sinus syndrome (SSS) associated with transient supraventricular tachyarrhythmia (atrial fibrillation [Af] in three patients, atrial flutter [AF] in two, and paroxysmal atrial tachyarrhythmia [PAT] in four). Various degrees of abnormality of atrioventricular (AV) conduction were observed at the time of pacemaker implantation in five patients. In this pacemaker, a DDD mode was active during sinus rhythm, but the mode changed, through a given cycle of high rale tracking at an upper rate limit (VRL), to VDI only during intrinsic atrial rate increases that were either normally or abnormally above the URL. The VDI mode automatically returned to DDD when the atrial rate fell below the URL. At follow-up periods of 7–12 months, this pacemaker appeared to be especially effective in those SSS patients with transient Af or AF. In the SSS patients with PAT, however, the FB mode was not active because the PAT rhythm was conducted to the ventricle without block (1:1 conduction) and thus the given cycles of ventricular tracking at the URL did not occur. From the repetitive FB starting tests that were performed during an Af period in one patient with transient Af, a 2:1 point setting of a given URL plus 30–50 ppm was required to quickly start the FB algorithm. Moreover, an atrial sensitivity setting that was less than half of the P wave amplitude was desirable. These results suggest that, when properly set, the DDD plus FB mode is useful in a SSS patient with transient supraventricular tachyarrhythmia when a significant degree of AV block is present. 相似文献

To virologically assess the efficacy of interferon therapy in chronic hepatitis C, either 5 or 10 MU/day natural interferon-α (IFNα) was administered to 57 patients with chronic hepatitis C for 38 weeks. A complete and sustained response (CR-SR), as evidenced by the absence of serum hepatitis C virus (HCV)-RNA during the administration period and at 6 months after the final administration of IFNα and a normal GPT level at 6 months after final administration, occurred in 42.6% (23/54) of subjects. Liver tissue was histologically evaluated using the histological activity index (HAI) score before and after the administration period. In CR-SR cases, significant improvements (P <0.01) occurred in periportal necrosis, intralobular necrosis, portal inflammation and total score. A comparison, by HCV genotypes, revealed that CR-SR occurred in 60% (9/15) of subjects with type 2a and 30.3% (10/33) of subjects with type Ib. A comparison by virus concentration revealed that CR-SR occurred in 71.4% (15/21) of those subjects having a virus concentration of < 105 copies/mL, but in only 24.2% (8/33) of those having a virus concentration of > 105 copies/mL. Analysis by a multiple logistic model revealed a strong correlation between the therapeutic effect of interferon therapy and the pre-administration virus concentration (P=0.0061) and genotype (P=0.0015). These results suggest that the preadministration virus concentration and genotype are both key factors affecting the therapeutic effect of interferon therapy in chronic hepatitis C and that the therapeutic effect of interferon is satisfactorily high, irrespective of virus concentration, in subjects with type 2a HCV, but varies depending on virus concentration in subjects with type 1b. 相似文献

The subcutaneous implantable cardioverter‐defibrillator (S‐ICD) is a useful option for patients with a single ventricle (SV) in which transvenous leads are contraindicated because of intracardiac shunts. We report a case in which a right parasternal lead placement was indicated for an S‐ICD in a resuscitated patient with an SV. There were significant changes in the magnitude of R to T waves ratio in the right compared to the left parasternal lead position. Screening in the right parasternal position is effective for selecting appropriate patients with congenital heart disease for S‐ICD implantations. 相似文献

During the past 18 years, 141 patients with rectal carcinomaunderwent curative sphincter-saving procedures. Local recurrencesoccurred in 17 patients, a recurrence rate of 12%. No significantcorrelation between the recurrence rate and the site of tumoror nodal involvement was found. Laparotomies were performedin 14 of the 17 patients with local recurrence. Thirteen patientsunderwent abdominoperineal excision. In five of them, the recurrentgrowths were completely resected, and they were thought to havedeveloped at the previously established suture line, while inthe remaining eight cases the operation was considered palliative.As the result of pathological study of these resected specimens,it is possible to draw the following conclusions:
- The length of the distal margin of the normal bowel should bemore than 4 cm in locally advanced cases.
- In patients whosesecond operation was not curative the recurrencesdid not developin the rectal stump or in the levator muscle,but in the pelvicwall.
- Local recurrence after sphincter-saving procedures couldbeeffectively avoided by adequate clearance of the pararectalsoft tissues which could contain viable cancer cells, includingthe lymphatics and vessels as well as the lymph nodes.
- Aftera sphincter-saving operation, the patient must be examinedundera strict follow-up regimen, because curative resectionof localrecurrent tumors by abdominoperineal excision willbe made possibleby earlier detection of the recurrence.

We present a rare case of leiomyoma of the urinary bladder that was diagnosed during pregnancy. To our knowledge, this is the fourth case of its kind to be reported in the literature. Ultrasonography, magnetic resonance imaging and biopsy were useful for making an accurate diagnosis in this case. The diagnosis was confirmed by suprapubic transcutaneous needle biopsy. The tumor was resected approximately 3 years after diagnosis, during which period the patient delivered a normal baby by caesarian section. 相似文献
