[Color Doppler and ultrasound-guided prostate biopsy in the diagnosis of prostatic neoplasm].

The diagnosis of prostate neoplasm is still limited today by the variable power of prediction of the three main surveys used: prostate-specific antigen (PSA), digito rectal exploration (DRE) and ultrasound transrectal (TRUS). The study aimed to estimate the benefits and the diagnostic impact of the color Doppler ultrasonography on the diagnosis of prostate neoplasm through biopsies targeted on areas with abnormal flow. With this purpose, 222 biopsies performed on 71 patients between 1997 and 1999 were considered, which led to a diagnosis of neoplasm in 36 patients. Of the 84 biopsies that revealed prostate adenocarcinoma, 74 (64.3%) were correlated to hypoechoic lesions with abnormal flow signals while 41 (35.6%) showed a benign pathology (prostatitis or benign prostatic hyperplasia) (p < 0.0011). In five patients (13%) who did not present any evident lesions at a first transrectal ultrasound, the diagnosis of neoplasm was made only through biopsies targeted on areas with abnormal flow. Therefore, the color Doppler exam can be used during prostate ultrasonography either to consolidate the diagnosis or to give a useful target in case of isoechoic lesions.

Primary tracheal neoplasms: recognition, diagnosis and evaluation.

Primary neoplasms of the trachea are much less common than malignancies of the larynx and lungs. Tracheal neoplasms account for less than 0.1 percent of all neoplasms. Their importance lies in the fact that they may initially be misdiagnosed, resulting in a delay in diagnosis ranging from months to years. The most common benign tracheal neoplasms are hemangiomas, squamous papillomas and fibromas. The most common tracheal malignancy is squamous cell carcinoma. Symptoms of these lesions are usually related to airway obstruction and include wheezing, dyspnea and cough.

Cardiac neoplasms: current diagnosis, pathology, and therapy.

Cardiac neoplasms remain enigmatic because of their rarity and protean clinical manifestations. Although surgery for benign cardiac neoplasms seems straightforward, certain difficulties in diagnosis and extirpation often exist. Newer diagnostic modalities including intraoperative transesophageal echocardiography seem promising and may provide better planning for the surgeon. Moreover, cardiac transplantation has provided relief for some patients with irresectable benign neoplasms. As ventricular arrhythmias may emanate from benign tumors, electrophysiologically guided extirpation may provide helpful control. Malignant cardiac tumors remain the true challenge, whether primary or metastatic, as little surgical or medical progress has resulted. This review examines nearly all diagnostic, pathological, histologic, and therapeutic aspects of benign and malignant cardiac tumors. Moreover, the various surgical approaches necessary for removal of resectable neoplasms are detailed.

Immunohistochemistry in the diagnosis of neoplasms of the central nervous system.

The diagnosis and evaluation of neoplasms of the central nervous system frequently involves the use of immunohistochemical stains. This article reviews some of the more commonly used markers including glial fibrillary acidic protein, synaptophysin, neurofilament protein, S-100 protein, epithelial membrane antigen, and cytokeratin markers. The focus of the discussion is on the use of these markers including their utility in resolving differential diagnostic issues. We also review the use of p53 and a variety of cell proliferation markers including proliferating cell nuclear antigen, Ki-67, MIB-1 and their potential role as adjuncts in the grading of tumors and their potential role in predicting tumor behavior.

[The role of ocular symptoms in the diagnosis of neoplasms of the central nervous system].

Eighty four patients with a diagnosis of a neoplasm of the central nervous system were examined; full ophthalmological examination was performed in all of them. They showed pathological signs in the ocular adnexa, abnormal positioning and motility of the eyes, nystagmus, poor visual acuity, defects of the visual field, pathological changes in the anterior and posterior segment of the eye. In general--abnormal signs in the visual system were seen in 84.5 p.c. of cases comprising all of the children. In a part of cases ocular signs and symptoms were the only ones which drew attention from the side of the patient.

[Closed needle-biopsy in the diagnosis of neoplasms].

The AA. demonstrate with this communication the validity of the needle biopsie for the diagnosis of neoplasms. They had used it for the breast, thyroid, flg and some other superficial tumefactions. In the mass-screening for the feminine neoplasms the clinical examination and the needle biopsy are very good method for a careful diagnosis.
