PURPOSE: The aim of this article was to investigate the efficacy of ultrasonography-guided core needle biopsy and prognostic factor analysis of breast cancer to plan overall treatment strategy. PATIENTS AND METHODS: A consecutive series of nonpalpable and palpable breast cancers constituted our study group (n= 201 lesions; mean size, 20.4 mm) Mean number of core samples was 3.4. Malignant lesions diagnosed with core biopsy underwent therapeutic surgical excision. Core biopsy and surgical excisions were compared for histologic type, grade, estrogen receptors (ERs), progesterone receptors (PgRs), and c-erbB2 levels. Cutoff values for ER, PgR, and c-erbB2 affecting the management strategy were selected as 10%, 10%, and 50%, respectively. RESULTS: Eighty-five lesions (42.3%) were malignant in core biopsy (mean size, 18.4 mm). Among these, 11 were inoperable and 13 were surgically excised at other institutions. In 61 lesions, core and surgical excision specimens were evaluated in the same institution (mean tumor size, 18.6 mm; range 6-60 mm). Concordance between the 2 biopsy methods was 85.2% (52 of 61) for histologic type of tumor, 68.8% (33 of 48) for tumor grade, 90% (27 of 30) for ER, 86.7% (26 of 30) for PgR, and 79.3% (23 of 29) for c-erbB2 levels. Appropriate site selection for sampling was indicated to be of paramount importance, especially in determining reliable ER, PgR, and c-erbB2 levels. CONCLUSION: Core needle biopsy of breast cancer is equally effective compared with surgical biopsy and can be used in overall treatment planning. However, appropriate site selection for sampling should be guaranteed using ultrasonographic guidance. 相似文献

The occurrence of both primary gastric lymphoma and gastric adenocarcinoma in the same patient is a rare entity. The possible causative factors of synchronous or metachronous occurrence of both malignancies and varieties in the treatment modalities are reviewed according to published cases in English language medical literature. 相似文献

AIM: This study aimed to determine a marker that predicts delirium using preoperative oxidative processes in patients undergoing cardiopulmonary bypass surgery. METHOD: Twelve of the 50 patients included in the study showed signs of delirium during postoperative follow-up. The Delirium Rating Scale was used in patients with delirium according to DSM-IV-TR in the postoperative period. Venous blood samples were obtained from the patients the day before and the day after the surgery to determine plasma antioxidant enzyme levels. RESULTS: While there were no differences in preoperative superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and malondialdehyde (MDA) levels in both groups, catalase (CAT) levels were significantly lower in the delirium group. Postoperative SOD and MDA levels were also higher in the delirium group, while the GSH-Px levels were found to be lower when compared with those during the preoperative period. In the nondelirium group, the postoperative MDA and GSH-Px levels were found to be lower than preoperative levels, and postoperative SOD levels were found to be higher than preoperative levels. CAT levels were lower in the delirium group when the pre- and postoperative levels were compared in both groups. The postoperative levels of SOD, GSH-Px and CAT in the nondelirium group and MDA in the delirium group were significantly higher than preoperative levels. CONCLUSION: Patients with low preoperative CAT levels appeared to be more susceptible to delirium than patients with higher CAT levels. 相似文献

Massive hemorrhage is an unusual complication of tracheotomy, and the most common causes are injury to the anterior jugular veins and the thyroid isthmus, or unrecognized variations of the vascular structures, such as the arteria thyroidea ima. We present a case of high-running innominate artery that ascends until the third tracheal ring and courses horizontally anterior to the trachea in a patient with laryngeal carcinoma. If not noticed during tracheolaryngeal surgery, trauma to this vessel and subsequent hemorrhage may be fatal. In this report, the case is presented and the surgical significance of this anomaly is emphasized. 相似文献

The objective of this study is to determine the characteristics of and changes in the medicolegal childhood deaths that occurred in the provincial center of Adana, and to contribute to the establishment of a database for the development of national and international policies. The study is a retrospective research examining the 1,110 cases in the age group 0 to 18, which were specified as medicolegal deaths in the provincial center of Adana-Turkey between the years 2000-2004. The cases were examined according to age, sex, causes of deaths, the origins and scenes of occurrence. Among all the deaths, 523 cases (47.2%) were seen in the age group of 0-6 years. Accidents account for 900 cases (81.1%), and blunt traumas (594 cases) represent the most common cause of deaths. The share of traffic accidents in total blunt traumas was found to be 441 cases (74.2%). And 270 (24.3%) of all medicolegal deaths occurred as a result of household accidents. The present study has also indicated that the home and surroundings represent the highest-risk areas. As a conclusion, setting up childhood injury prevention committees and providing training programs for parents will be effective for the prevention of childhood injuries and deaths. 相似文献

X-linked hydrocephalus, HSAS (hydrocephalus due to stenosis of aqueduct of Sylvius), MASA (mental retardation, aphasia, shuffling gait, and adducted thumbs), and CRASH (corpus callosum hypoplasia, retardation, adducted thumbs, spastic paraplegia, and hydrocephalus) syndromes are allelic disorders. X-linked hydrocephalus and associated phenotypes are due to mutations in the L1CAM gene, which has been identified as a coding neural cell adhesion molecule. We report two cases of L1 spectrum disorders within the same family. The first case was diagnosed by ultrasonographic examination prenatally and the second case was diagnosed postnatally. Both patients and their mothers carry a novel mutation of the L1CAM gene. In this family, nine X-linked hydrocephalus and five female carriers were found in three generations, and molecular genetic analysis was performed to detect the asymptomatic carriers. 相似文献
