BACKGROUND The ultimate therapy for acute cholecystitis is cholecystectomy. However, in critically ill elderly patients the mortality of emergency cholecystectomy may reach up to 30%. Open cholecystostomy performed under local anesthesia was considered to be the procedure of choice for treatment of acute cholecystitis in high-risk patients. In recent years,(More)
BACKGROUND Uniform and accurate reporting of surgical complications is the basis for quality control. We developed a computerized system for reporting and grading surgical complications in colorectal surgery. This study was conducted to evaluate this computerized reporting system. STUDY DESIGN A retrospective chart review was conducted of all surgical(More)
Cancer/Testis (CT) genes, normally expressed in germ line cells but also activated in a wide range of cancer types, often encode antigens that are immunogenic in cancer patients, and present potential for use as biomarkers and targets for immunotherapy. Using multiple in silico gene expression analysis technologies, including twice the number of expressed(More)
Identification of genes that are upregulated in tumors, and whose normal expression excludes adult somatic tissues but includes germline and/or embryonic tissues, has resulted in a rich variety of cancer antigens that are attractive targets for cancer vaccine and other therapeutic approaches. In the present study, we extended this approach to include genes(More)
We have performed cDNA microarray analyses to identify gene expression differences between highly invasive glioblastoma multiforme (GBM) and typically benign pilocytic astrocytomas (PA). Despite the significant clinical and pathological differences between the 2 tumor types, only 63 genes were found to exhibit 2-fold or greater overexpression in GBM as(More)
BACKGROUND This study was conducted to determine survival according to the expression of molecular markers in colorectal cancer (CRC) patients of various ethnic origins. METHODS Resection of primary tumor was conducted on 171 patients with CRC. Corresponding archived paraffin-embedded blocks were retrieved and tissue microarray (TMA) constructed.(More)
The potency of the immune response has still to be harnessed effectively to combat human cancers. However, the discovery of T-cell targets in melanomas and other tumors has raised the possibility that cancer vaccines can be used to induce a therapeutically effective immune response against cancer. The targets, cancer-testis (CT) antigens, are immunogenic(More)
BACKGROUND The clinical profile of breast cancer may vary among different ethnic groups living in the same country and therefore affect the yield of a breast cancer screening program. The present study attempts to better characterize the breast cancer clinical profile of Arab women compared with Jewish women in the greater Jerusalem area with a future aim(More)
Meningiomas are the most common primary intracranial tumors. Surgical resection remains the treatment of choice for these tumors. However, a significant number of tumors are not surgically accessible, recur, or become malignant, necessitating the repetition of surgery and sometimes radiation. Chemotherapy is rarely used and is generally not recognized as an(More)
OBJECTIVE Sporadic late-onset medullary carcinoma of the thyroid is quite rare. Usually, the patient presents with a thyroid mass or neck node metastasis along with high levels of calcitonin and preoperative fine needle aspiration biopsy suggestive of medullary carcinoma of the thyroid. The role of genetic testing in such individuals, along with testing of(More)
