Chronic interstitial nephritis: etiologic factors.

Whether chronic interstitial nephritis (pyelonephritis) mainly results from kidney infection is widely debated. We studies 101 patients with interstitial nephritis, selected from 320 patients with newly diagnosed chronic renal disease, for frequency of etiological factors. Eleven had no etiologic factor(s) identified; 89 had clearcut factor(s): anatomic abnormalities 31, analgesic abuse 20, hyperuricemia 11, nephrosclerosis 10, stones 9, sickle cell disease1, tuberculosis 1, multiple causes7. Bacterial infection (present in 27%) was found only with another preceding primary cause of renal damage. Analgesic abusers frequently denied drug ingestion; 15% had urinary tract infection and 20% classical papillary necrosis. Two had family histories of analgesic abuse with nephropathy. We conclude that interstitial nephritis is a common form of chronic renal disease, is seldom idiopathic, rarely results from bacterial infection alone in adults, and frequently results from analgesic abuse in the United States.

Cadmium nephropathy: monitoring for early evidence of renal dysfunction.

Prospective studies in humans comparing various tests of cadmium-induced nephropathy have not been reported. Consequently, it is not possible to ascertain which screening methods should be followed in order to detect early nephropathy at a reversible stage. To obtain such data, the authors studied 23 cadmium workers with periodic analyses of blood/urine cadmium levels, hair cadmium content, urinary cytologies, creatinine clearance and urinary levels of lysozyme, beta-2-microglobulins, immunoglobulins, and aminoacids. Blood/urine levels were useful only as indices of acute environmental exposure and not as predictors of total body content or possible nephropathy. Hair content was elevated in most workers. Urine cytology was not reliable. Until further data are available, it is suggested that all five measures of renal function be used in screening and follow-up of cadmium workers for preventing nephropathy.

Expression of inducible nitric oxide synthase in human lungs.

The aim of this study was to investigate the expression of inducible nitric oxide synthase (iNOS) in lungs of patients with or without adult respiratory distress syndrome (ARDS). We compared the expression of iNOS by immunohistochemical analysis and polymerase chain reaction in the human lungs collected during open-lung biopsy or at autopsy. The expression of iNOS mRNA was present in all lung samples; however, only 3 out of 11 lung samples showed weak staining for iNOS. Although the involvement of nitric oxide in animal models of ARDS is reported, production of nitric oxide in human lungs is still controversial. The data presented here suggest that human lungs express iNOS mRNA but that the production of iNOS protein may be tightly regulated and is expressed in pulmonary inflammation.

Cancer statistics, 2000.

The Surveillance Research Program of the American Cancer Society's Department of Epidemiology and Surveillance Research reports its annual compilation of estimated cancer incidence, mortality, and survival data for the United States in the year 2000. After 70 years of increases, the recorded number of total cancer deaths among men in the US declined for the first time from 1996 to 1997. This decrease in overall male mortality is the result of recent down-turns in lung and bronchus cancer deaths, prostate cancer deaths, and colon and rectum cancer deaths. Despite decreasing numbers of deaths from female breast cancer and colon and rectum cancer, mortality associated with lung and bronchus cancer among women continues to increase. Lung cancer is expected to account for 25% of all female cancer deaths in 2000. This report also includes a summary of global cancer mortality rates using data from the World Health Organization.

Cancer statistics, 2001.

Each year the American Cancer Society compiles estimates of the number of new cancer cases and deaths expected in the US in the current year and the most recent data on cancer incidence, mortality, and survival. An estimated 1,268,000 new cases of cancer will be diagnosed in the year 2001 and an estimated 553,400 Americans will die from cancer. Overall cancer incidence and death rates have continued to decrease in men and women since the early 1990s, and the decline in overall cancer mortality has been greater in recent years. Despite reductions in age-adjusted rates of cancer death, the total number of recorded cancer deaths in the US continues to increase, due to an aging and expanding population. Large disparities in cancer incidence and mortality across racial/ethnic groups continue. Black men and women experience higher incidence of cancer and poorer survival than white men and women. The disparity in survival reflects both diagnosis of cancer at later disease stages, and poorer survival within each stage of diagnosis.

Administering a healthy dose of security.

The article describes how a hospital located in a poor, crime-ridden section of a large city has made the most of in-house resources and public-private liaisons to improve security at its 113-acre campus. Details on the facility's double-pronged approach--tight internal security and strong external liaisons with businesses, law enforcement, and community groups--are provided.

Differences in histology between first and second primary lung cancer.

Data from the Surveillance, Epidemiology, and End Results (SEER) Program were used to compare the histological distribution of second lung cancer following an initial cancer of the lung, head and neck, and breast to primary lung carcinoma occurring as a first cancer. Following initial head and neck cancer or initial squamous cell carcinoma of the lung, the proportion of second primary lung cancer which was of squamous cell histology rose dramatically, while the proportion of pulmonary adenocarcinomas rose following initial adenocarcinoma of the lung. The histological distribution of lung cancer following an initial breast cancer in women was similar to the distribution of de novo lung cancer in women. These results persisted as the time interval between diagnosis of the two primaries was increased from 12 to 48 months. We conclude that the histology of a second primary lung cancer following an initial cancer of the lung or head and neck tends to repeat the histology of the initial cancer (field effect), and this observation is not likely to be due to misdiagnosis of a recurrence of the initial cancer.

Poor survival of treatment-related acute nonlymphocytic leukemia.

Population-based data on more than 1 million patients registered in the Surveillance, Epidemiology, and End-Results Program of the National Cancer Institute, 1973 to 1984, were analyzed to determine the survival of patients with de novo acute nonlymphocytic leukemia (ANLL) and following a first primary tumor treated (with chemotherapy and/or radiation therapy) or untreated. Cases that occurred within 12 months of the first malignant neoplasm were excluded. Survival was estimated using Cox proportional-hazards modeling, with age, sex, and specific type of ANLL as covariates. The 6271 patients with de novo ANLL had an estimated 12-month survival of 30%, while the 107 patients with treatment-related ANLL (radiation therapy, 60; chemotherapy, 29; both, 18) had an estimated 12-month survival of 10%. This is not due to lingering effects of the first tumor since ANLL following solid tumors not treated with chemotherapy or radiation therapy (118 cases) has similar survival (estimated 12-month survival, 36%) as de novo ANLL. We conclude that ANLL that occurs after chemotherapy or radiation therapy is biologically more aggressive and/or resistant to therapy than spontaneous ANLL. This provides a rationale for current studies on treatment-induced cellular changes and on more aggressive therapy for these patients.
