The patient was a 57-year-old female with the main complaint of left chest pain and gait disturbance. Multiple bone metastases were observed in the vertebral and pelvic bone. Pathological pressure fracture, stegnosis of the spinal canal and edematous changes in the spinal nerves, especially in the 4th and 5th thoracic vertebrae, were observed. The clinical pathological status was T4cN1M1b, OSS Stage IV. After 4 cycles of weekly doxorubicin (DXR) (20 mg/body)/docetaxel (TXT) (40 mg/body) therapy (day 1, day 8, day 15, 1-week recovery period) were given to the patient, CA15-3 had decreased from 1,200 U/ml to 28 U/ml. The histopathological effect was judged to be Grade 2. Thereafter, ICTP was increased to 12.7 ng/ml and after 2 cycles of the weekly DXR/TXT therapy (day 1, day 8, 2-week recovery period) had been added, the patient was able to walk. MRI of the thoracic vertebrae showed that the foci of bone metastasis had improved 9 months after the treatment with chemotherapeutics, and good PS was maintained. No serious adverse reactions were observed with the weekly DXR/TXT therapy. Therefore, weekly DXR/TXT therapy is considered to be effective in treating patients with bone metastasis. 相似文献

Background: Microvolt T‐wave alternans (TWA) has been proposed as a useful index to identify patients at risk of ventricular tachyarrhythmias. Recent studies have demonstrated that antiarrhythmic drugs, such as amiodarone and procainamide, decrease the prevalence of TWA. In this study, we tested whether TWA in patients on antiarrhythmic pharmacotherapy significantly predicts the recurrence of ventricular tachyarrhythmias in patients with dilated cardiomyopathy. Methods: To evaluate the ability to predict the recurrence of ventricular tachyarrhythmias, determinate TWA and left ventricular ejection fraction (LVEF) were prospectively assessed in 49 patients with ischemic or nonischemic dilated cardiomyopathy on antiarrhythmic pharmacotherapy for sustained ventricular tachycardia (VT) or ventricular fibrillation (VF). The pharmacotherapy consisted of class I (17 patients), III (29 patients), and IV (3 patients) antiarrhythmic drugs. The study endpoint was the first recurrence of sustained VT or VF on treatment during the follow‐up period. Results: TWA was positive on antiarrhythmic pharmacotherapy in 30 patients (61%). During a follow‐up of 13 ±; 11 months, the sustained VT or VF recurred in 21 of the 41 patients (51%) with available follow‐up data. The sensitivity of TWA and LVEF for predicting recurrence of ventricular tachyarrhythmias was 76 and 38%, specificity was 60 and 70%, positive predictive value was 67 and 57%, and negative predictive value was 71 and 52%. Kaplan‐Meier event‐free analysis revealed that TWA was a significant risk stratifier (P = 0.02), whereas LVEF was not. Conclusions: This prospective study suggests that TWA significantly predicts the recurrence of ventricular tachyarrhythmias, even on antiarrhythmic pharmacotherapy, in patients with dilated cardiomyopathy. TWA may also be a useful marker for evaluating the efficacy of antiarrhythmic drugs for ventricular tachyarrhythmias. A.N.E. 2001; 6(3):203–208 相似文献

The electron-microscopic features of a thyroid follicular adenoma with clear cell change is described. The tumor was 7 mm in size and located in the upper portion of the left lobe of the thyroid of a 29-year-old Japanese female. Its cut surface was pale brown in color and well demarcated. The lesion consisted of solid nests with pinpoint lumina. The cytoplasm of the tumor cells was completely clear, but slightly vesicular without oncocytic change. Electron-microscopic examination revealed that the cytoplasm of the tumor cells was filled with numerous empty vacuoles. The vacuoles consisted of dilated membranous structures, indicating that they had been formed from rough endoplasmic reticulum and Golgi apparatus. There was no accumulation of glycogen, mucin, or lipid. The dilated membranous structures in the cytoplasm may be related to the increased thyroglobulin synthesis by the tumor. 相似文献

We describe an 81-year-old Japanese woman who had a palm-sized, erythematous plaque with a nodular lesion on the lateral abdomen. The biopsy specimens taken from the erythematous plaque and reddish nodule show that bowenoid changes were present in the epidermis and epidermis to dermis, respectively. A sentinel lymph node biopsy (SNB) was performed with blue dye and radioisotope in her right groin region and two lymph nodes were found to be occupied by many atypical cells. The erythematous plaque with nodular lesion was completely removed with a 3-cm margin under general anesthesia, and complete regional lymph node dissection was also performed. In addition, high telomerase activity was seen in the erythema plaque while using a telomeric repeat amplification protocol assay. In conclusion, some instances of Bowen's disease might have high telomerase activity in the atypical cells and can progress to Bowen's carcinoma. The SNB was regarded as a useful method to detect early lymph node metastases in this case. 相似文献

Noninvasive markers reflecting repolarization inhomogeneity have been proposed to be useful indices for identifying patients at risk of ventricular arrhythmias based on organic heart disease. In this study, we clarify whether or not repolarization inhomogeneity markers are useful in patients with idiopathic ventricular tachycardia (VT). We investigated T-wave alternans (TWA) and corrected QT-interval dispersion (QTD) in 84 consecutive patients with idiopathic VT, 90 patients with VT associated with organic heart disease (organic VT), and 87 normal individuals. VT was defined as tachycardia lasting > or =5 consecutive ventricular ectopic beats at a rate of > or =120 beats/min. TWA was positive in 20 of 84 patients (24%) with idiopathic VT, 59 of 90 patients (66%) with organic VT, and 16 of 87 normal individuals (18%). The alternans voltage was 2.6 +/- 3.1 micro V in idiopathic VT patients, 5.6 +/- 6.4 micro V in organic VT patients, and 2.9 +/- 5.7 micro V in normal individuals. QTD were 53 +/- 20 ms in idiopathic VT patients, 92 +/- 20 ms in organic VT patients, 46 +/- 18 ms in normal individuals, respectively. A positive TWA test result was seen more (P <.01) frequently, and QTD was longer (P <.01) in organic VT patients compared to normal individuals, whereas there was no difference between idiopathic VT patients and normal individuals. In addition, in patients with idiopathic VT, neither did any of these measurements differ between patients with sustained VT (lasting for > or =30 s) and those with nonsustained VT. Noninvasive markers of repolarization inhomogeneity, such as TWA and QTD, are not useful for identifying patients with idiopathic VT. Repolarization inhomogeneity may not affect to the pathogenesis of idiopathic VT. 相似文献

A curious retrograde conduction in connection with the coronary sinus (CS) musculature was observed in 2 patients. After the failed ablation procedure, the atrial electrogram during ventricular pacing presented double potentials, the first component of which was sharp and with an activation sequence that was the same before ablation (CS distal to proximal). The second component of the double potentials was dull and had a decremental property; its activation sequence was in reverse (proximal to distal). In both cases, the first component disappeared after successful ablation. These findings suggest that the first component was the CS electrogram conducted over the accessory pathway and the second component was the left atrial electrogram conducted through the inter-atrial septum. The separation of each electrogram is probably the result of a block between the accessory pathway connected to the CS musculature and the left atrium. These are unusual cases of an accessory pathway connected to the CS musculature, which separates the left atrial myocardium at the distal portion from the ostium. 相似文献

INTRODUCTIONGallstone ileus, a rare complication of cholelithiasis and cholecystitis, is a relatively rare cause of alimentary tract obstruction. It is usually associated with a cholecystoenteric fistula through which a gallstone has passed into the gastrointestinal tract. Cholecystoenteric fistula uncommonly closes spontaneously, the period between formation and closure having rarely been reported. In addition, endoscopic detection of cholecystoenteric fistulous closure has seldom been reported.PRESENTATION OF CASEWe report a 51-year-old Japanese man with gallstone ileus in whom spontaneous closure of a cholecystoduodenal fistula was observed by endoscopy 2 weeks after laparoscopy-assisted enterolithotomy.DISCUSSIONLaparoscopy-assisted enterolithotomy for gallstone ileus allows direct diagnosis of gallstone ileus and assessment of the status of adhesions affecting the biliary tract.CONCLUSIONEndoscopic confirmation of fistulous closure after laparoscopy-assisted enterolithotomy is a minimally invasive approach that may avert the need for biliary surgery. 相似文献

Mycobacterium tuberculosis infection in patients with autosomal dominant polycystic kidney disease (ADPKD) is rare, and its diagnosis and treatment are difficult because numerous cysts are exposed to infection and antibiotics do not easily penetrate infected cysts. Here, we report the case of a 43-year-old Japanese man with disseminated urogenital tuberculosis (TB) and ADPKD without human immunodeficiency virus (HIV) infection. Delayed diagnosis and ineffective anti-TB chemotherapy worsened his condition. Finally, he underwent bilateral nephrectomy but experienced postoperative complications. In conclusion, kidney TB should be recognized as a cause of renal infection in ADPKD, and surgical treatment should be instituted without delay. The importance of early diagnosis and treatment cannot be overemphasized to prevent kidney TB deterioration. 相似文献

Global accessibility to clean water has stressed the need to develop advanced technologies for the removal of toxic organic and inorganic pollutants and pathogens from wastewater to meet stringent discharge water quality limits. Conventionally, the high separation efficiencies, relative low costs, small footprint, and ease of operation associated with integrated photocatalytic-membrane (IPM) technologies are gaining an all-inclusive attention. Conversely, photocatalysis and membrane technologies face some degree of setbacks, which limit their worldwide application in wastewater settings for the treatment of emerging contaminants. Therefore, this review elucidated titanium dioxide (TiO2), based on its unique properties (low cost, non-toxicity, biocompatibility, and high chemical stability), to have great potential in engineering photocatalytic-based membranes for reclamation of wastewater for re-use. The environmental pathway of TiO2 nanoparticles, membranes and configuration types, modification process, characteristics, and applications of IPMs in water settings are discussed. Future research and prospects of magnetized TiO2-based membrane technology is highlighted as a viable water purification technology to mitigate fouling in the membrane process and photocatalyst recoverability. In addition, exploring life cycle assessment research would also aid in utilizing the concept and pressing for large-scale application of this technology. 相似文献
