The comparison of dual phase Tc-99m MIBI and Tc-99m MDP scintimammography in the evaluation of breast masses: Preliminary report 总被引:1,自引:1,他引:0

The aim of this prospective study was to determine the diagnostic value of Tc-99m MDP scintimammography (SMG) for the detection of breast cancer in patients with breast masses and to compare the results with Tc-99m MIBI scintimammography. Twenty patients, categorized as suspicious, positive or benign for breast cancer according to the mammographic findings were included in the study. Dual phase Tc-99m MIBI and Tc-99m MDP SMG were performed in the prone lateral position within 5 days of each other. Although early and late Tc-99m MIBI SMG showed equal (90.4%) sensitivity, the specificity of late Tc-99m MIBI (87.5%) was found superior to early (62.5%) imaging. The overall sensitivity and specificity of early Tc-99m MDP SMG were 71.4% and 62.5%, respectively. Although late Tc-99m MDP imaging showed 100% specificity, its sensitivity was only 23.8%. In the patients with palpable masses, both early Tc-99m MDP and Tc-99m MIBI showed equal sensitivity (100%), but the sensitivity of early Tc-99m MIBI (37.5%) was found slightly higher than Tc-99m MDP (25.0%) for nonpalpable breast lesions. The sensitivity of Tc-99m MIBI and Tc-99m MDP SMG in detecting metastatic axillary involvement was 66.6% and 50%, respectively. High sensitivity and specificity together with its low cost, easy availability and the possibility of detecting bone metastases seems to make Tc-99m MDP a contributive agent in the evaluation of breast lesions as an alternative to Tc-99m MIBI. 相似文献

Adult intussusception secondary to inflammatory polyp occurs rarely. Imaging of intussusception on ultrasound, CT and MRI
has been previously described. In this report we describe a case of an adult intussusception secondary to inflammatory fibroid
polyp. Both the lead point (inflammatory fibroid polyp) and intussusception were depicted on multiplanar MR images. Findings
on MRI were confirmed at surgery and histopathological examination.

We describe a 9-year-old child with a history of trichoptysis caused by intrapulmonary teratoma and we present the CT and MRI findings of the teratoma. A heterogeneous mass containing cystic and solid elements was detected on both CT and MRI scans. Histopathological examination confirmed the diagnosis of teratoma. Teratomas arising from lung parenchyma, as in this case, are extremely rare in childhood. In the thoracic region, the most common localization of teratomas is the anterior mediastinal compartment. We also discuss the CT and MRI findings and the differential diagnosis of teratomas. 相似文献

Rocuronium is a non-depolarizing neuromuscular blocking agent which is associated with injection pain and induces withdrawal movement of the injected hand or arm or generalized movements of the body after intravenous injection. The aim of this randomized study was to compare the efficacy of pretreatment with oral dexketoprofen trometamol (Arvelles®; Group A) with placebo (Group P) without tourniquet to prevent the withdrawal response caused by rocuronium injection. The study cohort comprised 150 American Society of Anaesthesiologists class I–III patients aged 18–75 years who were scheduled to undergo elective surgery with general anesthesia. The patients response to rocuronium was graded using a 4-point scale [0 = no response; 1 = movement/withdrawal at the wrist only, 2 = movement/withdrawal involving the arm only (elbow/shoulder); 3 = generalized response]. The overall incidence of withdrawal movement after rocuronium injection was significantly lower in Group A (30.1 %) than in Group P (64.6 %) (p < 0.001). The incidence of score 0 withdrawal movements was higher in Group A (69.9 %) than in Group P (35.4 %), that of score 1 withdrawal movements was similar between groups (Group A 21.9 %; Group B 26.1 %) (p = 0.560) and that of score 2 withdrawal movements was lower in Group A (8.2 %) than in Group P (38.5 %) (p < 0.001). There were no score 3 withdrawal movements in either group (p > 0.05). These results demonstrate that the preemptive administration of dexketoprofen trometamol can attenuate the degree of withdrawal movements caused by the pain of the rocuronium injection. 相似文献

BackgroundPsoriasis is a chronic skin disease that can have severe psychosocial effects. The aim of this study was to assess the perspectives of psoriasis patients regarding their illness.MethodsOne hundred and ten psoriasis patients in the 18–65 age group were included. Data were collected via a “face to face interview” method. The questionnaire included mainly three topics (socio-demographic characteristics of patients; self-evaluations of patients about their disease; knowledge and attitudes about psoriasis).ResultsThe majority of the patients stated that psoriasis as a socially troubling disease. Almost half of them believed that “stress and unhappiness” was a predisposing factor of their illness. Belief that the occurrence of the disease was due to a contagious infectious agent was the second most frequent factor that patients emphasized. “Signs and symptoms of psoriasis” was the most frequent difficulty patients faced because of psoriasis. Most of the patients who still have their parents, those who have a closest friend in life, and more than half of the patients who have their closest friend at work all stated that there was a change in social relations, mostly arising from their counterparts. More than half of the married patients stated that there was a change in social relations, mostly arising from their spouses.ConclusionPsoriasis is more than a cosmetic nuisance and can be associated with psychosocial effects that seriously affect patients’ lives and social relations. Increasing the patients’ knowledge of the disease could have a positive effect on the relations the psoriasis patients have within their social environment. 相似文献

This is the report of a 33-year-old female patient who was admitted to the Emergency Department with bilateral capitellum humerus fracture after a fall from a height. The patient was surgically treated with open reduction and internal fixation for both elbows, with 3 Kirschner wires on the right elbow and one mini-fragment screw on the left. Surgical intervention was carried out in emergency conditions. Following an early physical rehabilitation programme at the end of the 1st week, the roentgenograms in the 9th week showed acceptable bone union. However, in the 2nd year of follow-up the patient had consistent pain and 35 degrees of flexion loss in her right elbow due to degenerative change. The literature reveals only two reports of such cases. Thus, this rare case of bilateral capitellum humerus showed that early mobilisation after anatomic reduction and stable fixation with a mini-screw provided the optimal outcome. 相似文献

Colorectal carcinoma (CRC) is the third most common cancer, and approximately 35%-55% of patients with CRC will develop hepatic metastases during the course of their disease. Surgical resection represents the only chance of long-term survival. The goal of surgery should be to resect all metastases with negative histological margins while preserving sufficient functional hepatic parenchyma. Although resection remains the only chance of long-term survival, management strategies should be tailored for each case. For patients with extensive metastatic disease who would otherwise be unresectable, the combination of advances in medical therapy, such as systemic chemotherapy (CTX), and the improvement in surgical techniques for metastatic disease, have enhanced prognosis with prolongation of the median survival rate and cure. The use of portal vein embolization and preoperative CTX may also increase the number of patients suitable for surgical treatment. Despite current treatment options, many patients still experience a recurrence after hepatic resection. More active systemic CTX agents are being used increasingly as adjuvant therapy either before or after surgery. Local tumor ablative therapies, such as microwave coagulation therapy and radiofrequency ablation therapy, should be considered as an adjunct to hepatic resection, in which resection cannot deal with all of the tumor lesions. Formulation of an individualized plan, which combines surgery with systemic CTX, is a necessary task of the multidisciplinary team. The aim of this paper is to discuss different approaches for patients that are treated due to CRC liver metastasis. 相似文献
