A Case Study And National Database Report Of Progressive Systemic Sclerosis And Associated Conditions, David Phillips, Barbara Phillips, David M. Mannino

David M. Mannino

We report the case of a 34-year-old white woman with a history of progressive systemic scleroderma (PSS) and diffuse alveolar hemorrhage (DAH) that may be either a rare complication of PSS or induced by D-penicillamine. The DAH progressed to hemoptysis and led to intubation for airway protection. The patient progressed to acute renal failure. Her chest x-ray revealed diffuse bilateral infiltrates. She developed pulmonary fibrosis with secondary pulmonary hypertension. She experienced a brief period of improvement of her respiratory status after steroid treatment. We also report a database of 21,442 decedents with PSS over a 15-year period from 1979 to …

Variability Of Target Volume Delineation In Cervical Esophageal Cancer, Patricia Tai, Jake Van Dyk, Edward Yu, Jerry Battista, Larry Stitt, Terry Coad

Edward Yu

PURPOSE: Three-dimensional (3D) conformal radiation therapy (CRT) assumes and requires the precise delineation of the target volume. To assess the consistency of target volume delineation by radiation oncologists, who treat esophageal cancers, we have performed a transCanada survey. MATERIALS AND METHODS: One of three case presentations, including CT scan images, of different stages of cervical esophageal cancer was randomly chosen and sent by mail. Respondents were asked to fill in questionnaires regarding treatment techniques and to outline boost target volumes for the primary tumor on CT scans, using ICRU-50 definitions. RESULTS: Of 58 radiation oncologists who agreed to participate, 48 …

Does Delay In Breast Irradiation Following Conservative Breast Surgery In Node-Negative Breast Cancer Patients Have An Impact On Risk Of Recurrence?, Olga Vujovic, Francisco Perera, A. Dar, Larry Stitt, Edward Yu, Sachi Voruganti, Pauline Truong

Edward Yu

PURPOSE: This retrospective review was conducted to determine if delay in the start of radiotherapy after definitive breast surgery had any detrimental effect on local recurrence or disease-free survival in node-negative breast cancer patients. METHODS AND MATERIALS: A total of 568 patients with T1-T2, N0 breast cancer were treated with breast-conserving surgery and breast irradiation, without adjuvant systemic therapy between January 1, 1985 and December 31, 1992, at the London Regional Cancer Centre. Adjuvant breast irradiation consisted either of 50 Gy in 25 fractions or 40 Gy in 15 or 16 fractions, followed by a boost of 10 Gy or …

Premature Mortality From Heart Diseases In Brazil. A Comparison With Other Countries[Portuguese], Paulo A. Lotufo Jan 1998

Premature Mortality From Heart Diseases In Brazil. A Comparison With Other Countries[Portuguese], Paulo A. Lotufo

Paulo A Lotufo

Chronic diseases have been the main cause of mortality in the Brazilian metropolitan areas since 1960. Circulatory diseases are the main causes of chronic diseases. The aim was to compare the heart disease related premature deaths in Brazil with other countries in 1984-87. Methods: We studied the deaths from the official mortality statistics from eight metropolitan areas with good assurance of information: Belém, Recife, Salvador, Belo Horizonte, Rio de Janeiro, São Paulo, Curitiba, Porto Alegre. Death causes analyzed were coronary heart disease (410-414); and heart diseases [ischemic heart disease (410-414) plus heart failure (428) plus, hypertension (401-404)]. The population was …

To study the most prescribed anti-hypertensive drugs, evaluating their agreement with established guidelines and drug cost. Methods - One hundred and forty one (101 women, mean age = 53.3 years) hypertensive patients who searched spontaneous attention were interviewed in a tertiary-care hospital. The inclusion criteria were previous diagnosis of hypertension and non cardiovascular complaints. Results - The majority of the 107 (75.9%) patients were on medical treatment. In those receiving monotherapy, thiazides were the most utilized drugs, followed by methyldopa, ACE inhibitors, calcium channel-blockers, a n d b e t a - b l o c k e r s …
