Percutaneous Cryoablation for Renal Cell Carcinoma.

Renal cell carcinoma (RCC) is the most common type of kidney cancer in adults. Nephron sparing resection (partial nephrectomy) has been the "gold standard" for the treatment of resectable disease. With the widespread use of cross sectional imaging techniques, more cases of renal cell cancers are detected at an early stage, i.

Systematic review of the mechanisms driving effective blood flow during adult CPR.

Background: High quality chest compressions is the most significant factor related to improved short-term and long-term outcome in cardiac arrest. However, considerable controversy exists over the mechanisms involved in driving blood flow.

Objectives: The aim of this systematic review is to elucidate major mechanisms involved in effective compression-mediated blood flow during adult cardiopulmonary resuscitation (CPR).

The Greek version of the 9-item European Heart Failure Self-care Behaviour Scale: a multidimensional or a uni-dimensional scale?

Objectives: To evaluate the dimensionality of the Greek version of the European Heart Failure Self-care Behaviour Scale (Gr9-EHFScBS) in a Greek-Cypriot population.

Background: EHFScBS is a valid and reliable scale which is widely used for assessing heart failure (HF) patients' self-care behaviors.

Methods: EHFScBS was translated into Greek and was administered to 128 Greek-Cypriot HF patients.

Extramedullary hemopoiesis.

Various chronic hematologic disorders that lead to ineffective hemopoiesis or inadequate bone marrow function (ie, chronic hemolytic anemias, thalassemia, sickle cell anemia, myelofibrosis of many causes, lymphoma, and leukemia) can potentially precipitate extramarrow new blood element creation. Extramarrow soft tissue that produces blood elements is called extramedullary hemopoietic tissue and the process extramedullary hemopoiesis (EMH). Sites commonly involved by EMH include the liver, spleen, lymph nodes, and most commonly, paravertebral regions, although other sites can sometimes be involved.

Amyloidosis: review and imaging findings.

Amyloidosis is a collection of pathophysiologically related disease entities caused by the extracellular deposition of abnormal fibrillar proteins called amyloid. The accumulation of amyloid may be systemic, involving many organs, or localized manifesting as infiltration of individual organs, or in the form of a focal, tumorlike lesion. Amyloidosis may develop in the setting of underlying conditions, usually chronic inflammatory diseases, in which case it is termed secondary, or it may involve no underlying disease and thus be primary or idiopathic.

Efficacy and safety of percutaneous cryoablation for stage 1A/B renal cell carcinoma: results of a prospective, single-arm, 5-year study.

Purpose: Percutaneous cryoablation is gaining in popularity as a viable treatment option for renal cell carcinoma (RCC). We present the 5-year oncologic outcomes of a prospective trial.

Methods: Over a 5-year period, we treated 134 consecutive patients with biopsy-proven RCC with CT-guided percutaneous cryoablation.

Renal tumor ablation.

Percutaneous, image-guided ablation for renal cell carcinoma (RCC) is an important treatment option for many patients. With more than 60,000 new cases every year and nearly three-fourths of those presenting as stage 1A, minimally invasive, nephron-sparing therapies have become the standard of care. Stage 1 A (<4cm, organ confined) disease presents the best scenario for percutaneous ablation.

TVT and TVT-Obturator: comparison of two operative procedures.

Aim: To compare two anti-incontinence operations: the tension-free vaginal tape (TVT) and the TVT-Obturator for the first two 75-patient groups.

Methods: One surgeon operated on two patient groups with urodynamically proven urinary stress incontinence. The first 75-patient group in 1998 included the first TVT procedures performed according to Ulmsten [Ulmsten U, Henriksson L, Johnson P, Varhos G.

Avicins, a family of triterpenoid saponins from Acacia victoriae (Bentham), suppress H-ras mutations and aneuploidy in a murine skin carcinogenesis model.

We tested the ability of avicins, a family of triterpenoid saponins obtained from Acacia victoriae (Bentham) (Leguminosae: Mimosoideae), to inhibit chemically induced mouse skin carcinogenesis. Varying doses of avicins were applied to shaved dorsal skin of SENCAR mice 15 min before application of 100 nmol of 7,12-dimethylbenz[a]anthracene (DMBA) twice a week for 4 weeks (complete carcinogenesis model). The dorsal skin of a second group of mice was treated with one dose of 10 nmol of DMBA.

Validity of self-reported colorectal cancer screening behavior.

End points for trials promoting cancer screening are often based on self-reported screening behavior. This study was designed to evaluate and optimize the reliability of a computer-assisted telephone interview for collecting self-reported colorectal cancer screening behavior. Cases who had received a fecal occult blood test (FOBT), flexible sigmoidoscopy, and/or colonoscopy, and controls who had no record of colorectal screening were identified among 40-75-year-old members of the Denver Kaiser Permanente Health Care Program and were contacted by telephone.

Thrombolytic therapy of massive pulmonary embolism during prolonged cardiac arrest using recombinant tissue-type plasminogen activator.

Cardiac arrest caused by massive pulmonary embolism is highly refractory to conventional resuscitation. Emergency surgical embolectomy has been considered the only effective intervention. We present the case of a 33-year-old woman who suffered a massive pulmonary embolism with circulatory arrest refractory to one half hour of aggressive CPR.

Neoplasms occurring in aged Fischer rats, with special reference to testicular, uterine, and thyroid tumors.

Inbred Fischer rats were set aside as nonbreeders specifically to obtain tumors of endocrine organs and endocrine-responsive tissues that might be used in studies of hormone responsivity. The average age at death or autopsy was 675 days for 102 females, and 725 days for 92 males. The tumor data are recorded for those animals that were autopsied (91%).
