Two elderly women complaining of intermittent claudication complicated with persistent sciatic artery are herein reported.
A direct femoral arteriogram showed hypoplasty of the superficial femoral artery and an unnatural anatomical relationship
between the distal superficial femoral artery and the proximal popliteal artery, thus suggesting the presence of persistent
sciatic artery. The diagnosis of persistent sciatic artery was finally made based on the aortography findings including the
iliac arterial system and computed tomography (CT) scan. Magnetic resonance imaging (MRI) was helpful to demonstrate the entire
image of this anomaly in cases with non-thrombolized sciatic artery. These diagnostic methods were useful in designing the
optimal surgical strategy. The first case with a gluteal pulsating mass underwent exclusion of the persistent sciatic artery
including the aneurysm through a retroperitoneal approach with a combination of femorotibial bypass, while the second case
with thrombosed persistent sciatic artery only underwent femoropopliteal bypass. To recognize such a rare lesion, awareness
of the differential diagnosis is important, and to provide appropriate treatment, an accurate whole image including adequate
angiography, a CT scan, and magnetic resonance imaging is necessary. 相似文献

S-1 plus cisplatin combination chemotherapy in patients with advanced non-small cell lung cancer: a multi-institutional phase II trial. 总被引:3,自引:0,他引:3

PURPOSE: To evaluate the efficacy and toxicity of a novel combination chemotherapeutic regimen including cisplatin with an oral anticancer agent, S-1 that consisted of tegafur, 5-chloro-2, 4-dihydroxypyridine, and potassium oxonate, for non-small-cell lung cancer (NSCLC) patients. EXPERIMENTAL DESIGN: In this phase II trial, patients with locally advanced and metastatic NSCLC were treated with the oral administration of S-1 at 40 mg/m(2) twice a day for 21 consecutive days while cisplatin (60 mg/m(2)) was administered intravenously on day 8. This schedule was repeated every 5 weeks. RESULTS: Of 56 patients enrolled in the study, 55 patients were eligible and analyzed. The median number of cycles administered was 3 (range, 1-12 cycles). Among these 55 patients, one complete response and 25 partial responses were observed with an overall response rate of 47% (95% confidence interval, 34-61%). The median survival time was 11 months and the 1-year survival rate was 45%. Hematologic toxicities of grades 3 and 4 included neutropenia (29%) and anemia (22%). No grade 4 nonhematologic toxicity was observed. Grade 3 toxicity included anorexia (13%), vomiting (7%), or diarrhea (7%). CONCLUSIONS: S-1 plus cisplatin combination chemotherapy showed a promising effectiveness with acceptable toxicity rates in patients with advanced NSCLC. These results warrant further investigations of this regimen including a randomized controlled trial for its use as a first line treatment for NSCLC. 相似文献

Abstract – An 11‐year‐old male who injured his maxilla and right maxillary central incisor and lip during a fall was presented to our hospital. His lower lip and upper gingiva were lacerated with swelling and epistaxis, and he had a maxillary alveolar bone fracture and severe intrusion of the right maxillary central incisor, which had penetrated the floor of the nasal cavity with avulsion. Under local anesthesia, we repositioned the incisor and bone segment and fixed them with a titanium micromesh plate and self‐tapping screws and splints. The incisor was also treated by root canal 3 days after the operation and was restored with a crown. We performed root canal filling 1 month later. Five months later, the plate and screws were removed. In prognosis of our case, no symptoms of inflammatory root resorption or ankylosis have observed for more than 1 year and 6 months of follow up based on both clinical and radiographic findings. 相似文献

The aim of this study was to examine the effectiveness of covering wounds to the tongue with a polyglycolic acid (PGA) sheet and fibrin glue. Eighteen mature male Japanese white rabbits had a unilateral glossectomy involving an area 10mm×10mm×2mm. After glossectomy the tongues were covered with PGA sheets 8mm×8mm in size and fibrin glue (mucosal defect covered with fibrin glue and polyglycolic acid sheet=MCFP) 1 week after the operation (n=3), after 2 weeks (n=3), and after 4 weeks (n=3). In control groups, after 1, 2, and 4 weeks (n=3 in each group), the partially resected tongues were closed with absorbable sutures (polyglactin 910). One week (experimental and control groups 1), 2 weeks (experimental and control groups 2) and 4 weeks (experimental and control groups 3) after operation the tongues were harvested and stained for microscopic examination. Histological examination showed that the covered wound surface had not epithelialised and the basal layer had yet to form in experimental group 1, but had formed in experimental group 2. However, in control group 1, epithelialisation of the sutured wound had begun. Immunohistochemical examination showed that, in experimental group 1, the non-uniform epithelial layer of the covered wound surface expressed cytokeratin AE1/AE3, and the epithelial and connective tissue layers stained strongly for FGF-2. Similar results were obtained in experimental group 2, whereas in experimental group 3, FGF-2 was expressed only in the connective tissue layer, and epithelialisation was complete. However, in control group 1, AE1/AE3 was expressed in the epithelial layer, and FGF was expressed in the connective tissue layer beneath the basal layer. In control groups 2 and 3, AE1/AE3 and FGF-2 were expressed in patterns similar to those in experimental groups 2 and 3. We suggest that this method is useful and the operation is simple. However, further testing of the method is needed and it should be widely used clinically before it is recommended. 相似文献

ObjectivePostoperative radioactive iodine (RAI) adjuvant therapy improves the prognosis in patients with advanced papillary thyroid carcinoma (PTC), although the role of RAI adjuvant therapy remains unclear in intermediate-risk patients, as defined by the American Thyroid Association. The ATA cautiously recommended RAI adjuvant therapy in patients with T1–3N1b, but the Japanese Society of Thyroid Surgery suggests lobectomy without RAI adjuvant therapy in these patients. This study assessed the role and efficacy of RAI adjuvant therapy in patients with T1–3N1b PTC.MethodsA single-center retrospective observational study was performed. We included patients with T1–3N1bM0 PTC who underwent complete resection between January 2003 and December 2017. Patients with bilateral PTC were excluded. We compared recurrence rates after surgery with RAI adjuvant therapy and surgery alone.ResultsA total of 61 patients (male:female ratio, 18:43; mean age, 57.1 ± 16.7 years) were included, and the median follow-up period was 6.8 years. Of the included patients, 33 were treated with surgery with RAI adjuvant therapy and 28 were treated with surgery alone. The RAI treatment group that underwent surgery had larger tumors, more lymph node metastases, and were younger. There were no disease-specific deaths, and 10 patients experienced local recurrence. The recurrence rate was 24.2% in patients who underwent surgery with RAI adjuvant therapy and 7.1% in patients who underwent surgery alone. Compared to T1–2 stage patients, the T3 stage patients tended to have a higher recurrence rate (odds ratio, 2.38; 95% confidence interval, 0.51–10.7).ConclusionsThe recurrence rate was higher in patients who underwent surgery with RAI adjuvant therapy than in patients who underwent surgery alone. Patients in the former group had larger tumors and more lymph node metastases, and this difference in baseline characteristics could explain their higher recurrence rate. The recurrence rate was lower in patients with small tumors, and RAI adjuvant therapy would likely not play a major role in T1–2N1bM0 patients. 相似文献
