Local Control and Cosmetic Outcome after Sector Resection with or without Radiation Therapy for Early Breast Cancer

Breast conserving surgery and radiation therapy (RT) can achieve a more favorable cosmetic outcome than mastectomy in patients with early breast cancer. However, it is widely recognized that RT is an impediment to improving the cosmetic outcome. Between 1985 and 1993, 113 patients were enrolled in a prospective randomized study to examine whether or not RT could be avoided following sector resection in patients with Stage I and II (UICC) invasive breast cancer. There was no significant difference in the 8 year local recurrence free survival rate between the RT and non-RT groups (92.3% versus 89.8% respectively). The characteristics of suitable patients would be negative nodes and microscopically negative resection margins. In conclusion, sector resection without RT is a reasonable option for some patients with early breast cancer.     

Prednisolone plus low-dose aspirin improves the implantation rate in women with autoimmune conditions who are undergoing in vitro fertilization

Objective: To evaluate the effect of prednisolone plus low-dose aspirin (PSL/LDA) in women with autoimmune conditions who were enrolled in an IVF-ET program.

Design: A retrospective clinical study.

Setting: In vitro fertilization unit, Niigata University Hospital, Niigata, Japan.

Patient(s): Three hundred seven women who underwent IVF-ET between January 1996 and December 1997.

Intervention(s): Prednisolone (10 mg/d) and aspirin (81 mg/d) were administered to the women with autoantibodies who chose to participate.

Main Outcome Measure(s): Pregnancy and implantation rates with IVF-ET.

Result(s): Women undergoing IVF who had positive antinuclear antibodies, with or without antiphospholipid antibodies, had significantly lower pregnancy and implantation rates than did women without autoantibodies (14.8% versus 21.7% and 6.8% versus 10.4%, respectively). The administration of PSL/LDA to women with antinuclear antibodies significantly improved the outcome of IVF-ET (40.6% pregnancy rate and 20.3% implantation rate).

Conclusion(s): A high proportion of women who are undergoing IVF-ET have autoantibodies, which are associated with poor IVF outcomes. The administration of PSL/LDA to these women may improve their implantation rate.     

Potential extraperitoneal space continuous with the peri-intestinal space: CT evidence and anatomical evaluation in patients with pneumatosis intestinalis without intestinal ischemia

Purpose  

Extraperitoneal spaces, such as the mesenteric space and the retroperitoneal space, can serve as areas that enable a reduction in the pressure exerted by extraperitoneal fluid collection and infiltrating diseases. In clinical practice, understanding the existence of these decompression spaces (or pathways) is very important for making accurate diagnoses. Here, we evaluated potential anatomical extraperitoneal spaces based on the extraluminal gas distribution in patients with pneumatosis intestinalis without intestinal ischemia.     

Heparin-induced thrombocytopenia with multiple organized thrombi accompanied by unusual cholesterin deposition: Autopsy case after long-term follow up

Heparin-induced thrombocytopenia (HIT) is characterized by a reduction in the platelet count and systemic thromboembolism during heparin therapy. Herein is reported a case of HIT with characteristic thrombus formation. A 68-year-old man who had been treated for hypertension for 27 years suffered a brain infarction and was treated with heparin. After this treatment, other new infarctions occurred in multiple organs. Because serum antibodies against heparin/PF4 complex were detected, he was diagnosed as having HIT, and warfarin and argatroban were administered instead of heparin. He died, however, 119 days after the first onset. At autopsy infarction due to organized thrombi with cholesterin deposition in multiple organs were found, similar to usual atherosclerotic emboli, but different to them with regard to clinical course and distribution of thrombi. This case in which organization and frequent cholesterin deposition were found in thromboembolized lesions of multiple organs after relatively long-term follow up, is unusual. The findings suggest that HIT accompanied by marked hypercholesterolemia of long duration contributes to a characteristic form of thromboembolism that needs careful management.     

Incidence of food residue interfering with postoperative endoscopic examination for gastric pull-up after esophagectomy

Background

In spite of appropriate preparation, food residue that interferes with endoscopic examination is occasionally observed in an operated stomach. The present study aimed to elucidate the incidence of such food residue and determine its risk factors in gastric pull-up after esophagectomy.

Methods

A total of 116 esophagectomized patients underwent the first postoperative endoscopy to survey their gastric pull-up with a median interval of 14 months (range 6–24) after the surgery. Fasting time was 13–16 h before the examination. The amount of food residue was retrospectively classified from Grade 0 (no food residue) to Grade 4 (a large amount of food residue) by two expert endoscopists.

Results

Among the 116 patients, 73 patients were classified as Grade 0, 23 patients as Grade 1, 10 patients as Grade 2, 9 patients as Grade 3, and 1 patient as Grade 4. Food residue (≥Grade 2) that interfered with the examination was observed in 20 patients (17.2 %). There was no significant association between the food residue and patient baseline characteristics.

Conclusion

The food residue interfering with postoperative endoscopic examination was observed in 17.2 % of all surveyed gastric pull-ups.

     

Non-invasive detection of coronary artery disease by body surface electrocardiographic mapping after dipyridamole infusion

Electrocardiographic changes after dipyridamole infusion (0.568 mg/kg/4 min) were studied in 41 patients with coronary artery disease and compared with those after submaximal treadmill exercise by use of the body surface mapping technique. Patients were divided into three groups; 19 patients without myocardial infarction (non-MI group), 14 with anterior infarction (ANT-MI) and eight with inferior infarction (INF-MI). Eighty-seven unipolar electrocardiograms (ECGs) distributed over the entire thoracic surface were simultaneously recorded. After dipyridamole, ischemic ST-segment depression (0.05 mV or more) was observed in 84% of the non-MI group, 29% of the ANT-MI group, 63% of the INF-MI group and 61% of the total population. Exercise-induced ST depression was observed in 84% of the non-MI group, 43% of the ANT-MI group, 38% of the INF-MI group and 61% of the total. For individual patients, there were no obvious differences between the body surface distribution of ST depression in both tests. The increase in pressure rate product after dipyridamole was significantly less than that during the treadmill exercise. The data suggest that the dipyridamole-induced myocardial ischemia is caused by the inhomogenous distribution of myocardial blood flow. We conclude that the dipyridamole ECG test is as useful as the exercise ECG test for the assessment of coronary artery disease.
