[Delay in the diagnosis of cancer].

OBJECTIVE: A reduction in the time used to be able to diagnose an illness influences not only the well being of the patient but also the quality of the medical care. In this work, we have studied the amount of time needed to diagnose cancer. MATERIAL AND METHOD: Descriptive methods have been used: average, median, mode and standard deviation in order to know how long it takes to diagnose and treat cancer. The data have been taken from a hospital register. RESULTS: The longest time elapsed between the periods appears to be the one between the first symptoms and the date the diagnosis is made, which has been calculated to be 96 days on average. The remaining time periods studied showed a time lapse of about 26 days on median. DISCUSSION: The median has been taken as the measurement chosen to assess these time periods, which have been notably reduced in the last decade. CONCLUSIONS: The performance of the primary care doctor is of great importance, as he is normally the one who is faced with the precocious symptoms, as well as with the risk factors that persist in the patients. This doctor is therefore the one who can initiate both the early diagnosis and the medical education of the patients.

[Leucocyte chemotaxis in patients treated with chronic haemodialysis (author's transl)].

Granulocytic and monocytic chemotaxis are studied by means of Boyden's modified method using as chemotactic agent human serum complement activated by Zymosan. The study has been made on healthy controls and a group of patients suffering from chronic renal failure treated with periodic haemodialysis. Observations were made before and after the dialysis session. In the patients with chronic renal failure is observed a decrease in leucocytic mobility of granulocytes and monocytes which give chemotactic granulocytic and monocytic indexes of 32.1 +/- 3.1 and 32.3 +/- 3.5 with relation to healthy controls with indexes of 46.7 +/- 8.4 and 37.0 +/- 4.3 and with significative differences between the measurements of p less than 0.001 and p less than 0.005 respectively. The parametres of polymorphonuclear and monocytic kinetics did not improve after the haemodialysis session. The possible mechanisms which produce such chemotactic leucocytic deficit in uraemics and the non-positive influence of the dialysis session on such deficit are hereby discussed.

[Aging of the population and incidence of primary acquired hemopathies in the Autonomous Community of Aragón].

BACKGROUND: Aging probably comprises one of the major factors contributing to the onset of acquired primary blood diseases (APBD's) most of which are of a chronic type. The purpose of this study is to analyze the rate of occurrence (RO) of HPA in a population of 522,621 inhabitants (Males: 252,721; Females: 269,900) showing a negative vegetative growth (-1.4/10(5) inhabitants/year), said occurrence being dealt with separately for the population under age 60 and the population over age 60. METHODS: In January-December, 1994, a estimate was made of the HPA rate of occurrence and rate of analyses among the patients from the area in question, dealing separately with those under age 60 and over age 60. The diagnostic criteria applied were Monoclonal Gammopathies of Undetermined Significance (MGUS's) in keeping with Kyle's criteria. Multiple Myeloma (MM) and Chronic Lymphatic Leukemia (CLL) in keeping with the Myeloma Task Force criteria. Non-Hodgkin's Lymphoma (NHL) and Hodgkin's Disease (HD) in keeping with the REAL classification, Myelodisplasic Syndromes (MS's) and Acute Leukemia (AL) in keeping with the FAB classification, Chronic Myeloproliferative Syndromes (CMS's) in keeping with the PVSG. For calculating the rates of occurrence, descriptive epidemiological methods were used. RESULTS: The highest rates of blood analyses as the result of suspected APH's fell within the over 60 age group (p < 0.0001). During the length of time analyzed, a total of 302 APH's (< 60/> or = years: 100/202, p < 0.0001) were diagnosis, being worthy of special mention: 84 MGUS's; 21 MM's; 57 NHL's; 26 CLL's; 33 CMS's; 11 AL's and 14 HD's. The spread by gender was: Males: 177; Females 125. Average age: 63.54 years (age range 19-92). The rates of occurrence (cases/10(5) inhabitants/year) were (< age 60/> or = age 60): overall: 31.31/178.86; MGUS: 7.37/52.87; MM: 1.84/13.21; NHL: 5.53/34.36; CLL: 1.53/18.50; MS: 0.62/27.31; CMS: 5.52/16.74; AL: 1.53/5.29; HD: 3.68/1.76. CONCLUSIONS: The highest rate of analyses as the result of suspected APH was found among those over 60 years of age. The overall occurrence of APH is significantly higher in those over age 60, as well as for each type of APH taken into account, except for AL and HD. The highest rate of occurrence is that of MGUS, NHL and MS's, especially in males.
