A 58-yr-old male with a history of hepatitis C virus infection, presented with a 2-mo history of intractable left upper abdominal pain. He had fallen from a ladder 2 yr previously, landing on his left side. Abdominal computed tomography identified a large cystic mass in the spleen. The patient was brought to the operating room with a presumptive diagnosis of symptomatic, post-traumatic, false cyst of the spleen. Instead, at surgery, a splenic mass with dense adhesions to the diaphragm and stomach was found. On final histological analysis, it was diagnosed to be a large B-cell lymphoma. Despite its rarity, gastroenterologists and surgeons should be aware of large B-cell lymphoma when encountering cystic lesions of the spleen, because the management of benign cystic disease is usually nonsurgical. 相似文献

A case of minute squamous cell carcinoma arising in a congenital lung cyst is reported. Two aspects of this case were notable. First, we were able to make the diagnosis of squamous cell carcinoma by bronchial lavage at an early stage. Second, to our knowledge, this is the first case of probable de novo origin of squamous cell carcinoma in a congenital lung cyst. 相似文献

We have developed a photoacoustics-based imaging system, the dual-scan mammoscope (DSM), that combines optical contrasts with acoustic detection, to obtain the angiographic features in human breast. In this study, we investigated whether the system can differentiate malignant tumor and healthy breast. We have imaged 38 patients with various tumor types and compared results of tumor-bearing breast with healthy breast for each patient. We also compared the photoacoustic and ultrasound imaging results with clinical US. Vascular features in and around the tumor mass were visualized. We found that tumor-bearing breast contained vessels of larger caliber and exhibited stronger variations in the background signals than those in the contralateral healthy breasts. Preliminary data on photoacoustic and ultrasound images also indicate that the technique has potential in differentiating different tumor types. Overall, our results indicate that combining photoacoustic and ultrasound images can improve breast cancer screening. 相似文献

To estimate the carbohydrate‐to‐insulin ratio (CIR), a formula dividing a constant, usually 300–500, by the total daily dose (TDD) of insulin, is widely utilized. An appropriate CIR varies for each meal of the day, however. Here, we investigate diurnal variation of CIR in hospitalized Japanese type 1 diabetic patients treated with continuous subcutaneous insulin infusion. After optimization of the insulin dose, TDD and total basal insulin dose (TBD) were 34.9 ± 10.2 and 9.3 ± 2.8 units, respectively, with a percentage of TBD to TDD of 27.3 ± 6.0%. The products of CIR and TDD at breakfast, lunch and dinner were 311 ± 63, 530 ± 161, and 396 ± 63, respectively, suggesting that in the formula estimating CIR using TDD, the constant should vary for each meal of the day, and that 300, 500, and 400 are appropriate for breakfast, lunch, and dinner, respectively. 相似文献

The detection of gene mutation of epithelial growth factor receptor (EGFR) is important to predict the therapeutic effect of gefitinib. Recently, it was reported that examination of the activation of the downstream protein of EGFR is useful in the same way as the EGFR mutation. Therefore the purpose of the present paper was to determine whether activation of Akt and Erk, which are downstream proteins, and the EGFR gene mutation pattern was correlated. A total of 130 pulmonary adenocarcinomas were studied for the gene mutations of EGFR in exon 19 and 21, and the phosphorylation of Akt and Erk was investigated by immunostaining. The EGFR mutation was detected in 32%, the positivity of p-Akt was 51%, and the rate of p-Erk was 27%. The EGFR mutation-positive cases were the minority in p-Akt-negative cases, and the p-Akt expression was significantly associated with the mutation of EGFR (P=0.0014). In addition, there was a significant correlation between the L858R mutation and the expression of p-Akt (P=0.040). It is suggested that the activation of Akt is dependent on EGFR mutation pattern. 相似文献
