Postphlebitic syndrome and general surgery: an epidemiologic investigation.

Of a random sample comprising 4581 subjects from The Copenhagen County, 3608 (79%) attended an interview and a general health examination. The subjects were defined as suffering from subjective postphlebitic syndrome if they claimed of lower extremity pain or cramps at rest and from objective postphlebitic syndrome if varicose veins, edema, lower extremity ulcers, or skin changes were present. By means of logistic regression analysis, subjective postphlebitic syndrome was found independently associated with previous thromboembolism, obesity, increasing age, female sex, hormonal therapy, varicose veins, and previous major abdominal surgery. Objective postphlebitic syndrome was associated with previous thromboembolism, obesity, former birthgiving, and high social status. The findings support the view that subclinical deep venous thrombosis in connection with previous surgery may give rise to symptoms in the lower extremities.

Iron stores in 1433, 30- to 60-year-old Danish males. Evaluation by serum ferritin and haemoglobin.

Iron status including S-ferritin and haemoglobin (Hb) was assessed in a population survey comprising 1433 Danish males in age cohorts of 30, 40, 50 and 60 years. There was no significant difference in S-ferritin levels between the age groups. In the entire series, median S-ferritin was 126 micrograms 1-1, 5-95% tile 31-378 micrograms 1-1, range 5-3600 micrograms 1-1; 1.2% had values less than 15 micrograms 1-1 (i.e. depleted iron stores), 3.7% values from 15-30 micrograms 1-1 (i.e. small iron stores), and 95.1% values greater than 30 micrograms 1-1 (i.e. replete iron stores); 73.8% had values from 61-300 micrograms 1-1, and 9.5% values greater than 300 micrograms 1-1. Blood donors had lower S-ferritin than non-donors and a higher frequency of depleted iron stores (p less than 0.0001). Hb values showed no age variation; median values was 155 g 1-1 (9.6 mmol 1-1), 5-95% tile 137-171 g 1-1 (8.5-10.6 mmol 1-1). Hb values less than 129 g 1-1 (8.0 mmol 1-1) were observed in 1.7%, and values less than 121 g 1-1 (7.5 mmol 1-1) in 0.8%. Males with S-ferritin less than 15 micrograms 1-1 (n = 17) had lower Hb, median 148 g 1-1 (9.2 mmol 1-1), than those with S-ferritin greater than or equal to 15 micrograms 1-1, median 155 g 1-1 (9.6 mmol 1-1) (p less than 0.05).(ABSTRACT TRUNCATED AT 250 WORDS)
